3 Bundle sha1 rather than use libgcrypt/nettle. This means that
4 configure no longer accepts --with-gcrypt and --with-nettle.

27 ZOOM C: tweak when connection failed is returned
28 For cases with multiple socket addresses for some hostname, eg
29 localhost IPV4+IPV6, the code now properly returns "connection
30 failed" rather than "connection lost".

92 Document zoom extraArgs YAZ-817
94 Fix ZOOM: crash extended services diagnostics YAZ-846
95 The immediate fix is to prevent ZOOM_set_dset_error from removing
96 current task from connection. This, however, has been assumed in a
97 number of places so this fix is rather large unfortunately.

172 Unfortunately a regression occurred with YAZ 5.10.0 that would make
173 Pazpar2 fail for HTTP connections.
175 --- 5.10.0 2015/03/03
177 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
178 Introduce cs_create_host2 which returns if connection should be
179 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
180 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).

225 Try to fix the situation where parent process stops before
226 child has acknowledged it .. SIGUSR2 back!
228 daemon: log message when keepalive stops.
232 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
233 would make yaz-marcdump crash when from-character set was issued.
237 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
238 New function yaz_enable_panic_backtrace which enables backtrace
239 handler for current process. The handler will call backtrace always,
240 then gdb to provide as much detail as possible.
244 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
245 and ZOOM record render will inspect leader 9 and switch to UTF-8
246 (Unicode) if that holds 'a'. This changes behavior, but is considered
247 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800

291 CCL YAZ-781: for multiple use attributes in a specification the
292 generated RPN will perform @or on each term.
293 For spec: term u=31 u=1016
294 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
296 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
298 CCL YAZ-779: combo qualifier should allow for forward references
300 Fix buildconf.sh, automake too old on centos5 YAZ-778
301 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
302 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
303 accepts it without a warning.
307 GFS: client_query_charset conversion YAZ-777
308 This is a feature for Z39.50 clients that sends queries that are not
309 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
310 encoding given to UTF-8.
312 Echoed SRU arguments support YAZ-776
313 This is achieved with new function yaz_srw_get_pdu_e.
315 ZOOM: expire times set for redis/memcached YAZ-772
316 For both redis and memcached option --expire=seconds sets expire
317 time for a result-set/search. Default time is 600 seconds (10 minutes).
321 No [rest of output is omitted] limit for yaz_log YAZ-774
323 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
325 For ICU testing, pass -o to yaz-icu. This will test the
326 icu_iter_get_org_info function.
328 Fix null ptr reference for freeReplyObject YAZ-773
332 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
334 RPM: do not build with libmemcached support. The libmemcached library
335 on CentOS 5/6 does not work reliably for us (redis to the rescue).
337 configure: only allow libmemcached version 0.40 or later. That's the version
338 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
339 that's not an option, consider redis.
343 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
345 Fix zoom+memcached: present request out of range YAZ-767
349 CCL: add new qualifier r=omiteq which will omit relation=equals
350 for ordered relations. This should be used in combination with either
353 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
355 Solr: simplify yaz_solr_decode_response
357 Solr: use different local var for string manipulation

374 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
378 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
380 zoomsh: offer option -a apdulog
381 As we're used to from yaz-client and GFS based servers.
383 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
384 existing setting apdulog takes effect.
386 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
391 Add re-entrant CQL/Solr/RPN query conversion functions.
392 The re-entrant functions are: cql_transform_r,
393 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
394 These have same functionality as cql_transform,
395 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
396 return the additional infomration as WRBUF to make them re-entrant.
398 Remove CQL to Solr conversion and base solr_transform_t on
399 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
400 data structure as cql_transform_t.
402 cql2pqf utility allows RPN to Solr conversion
404 Fix assert in ZOOM when http connect fails YAZ-757
406 --- 5.0.22 2014/04/09

410 wrbuf_cstr: make it thread safe YAZ-753
412 yaz_log_init_file may take fd=<no> to open log file at the FD given.
414 --- 5.0.21 2014/03/21
416 Offer new utility function zget_AttributeList_use_string.
418 New conversion step, solrmarc, for record conversion module.
420 --- 5.0.20 2014/03/13
422 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
423 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
426 --- 5.0.19 2014/03/10
428 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
429 The standalone ZOOM sort was completely broken since 5.0.13.
431 ZOOM: generate event Connect rather than None for partial connect
432 (in fact getaddrinfo resolving).
434 ZOOM: only supply clientIP for InitRequest. Rather than for all
437 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
439 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
440 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
441 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
443 New "Facets" section in the documentation.
445 --- 5.0.18 2014/02/27
447 Call exsltRegisterAll in yaz_init_globals, so that all applications
448 using YAZ will have EXSLT things enabled.
450 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
452 Update various URLs to the re-organized SRU pages at LoC.
454 --- 5.0.17 2014/02/26
456 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
457 introduced in 5.0.12.
459 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
460 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
461 Do not call yaz_init_globals from log_mask_str_x. Problem introduce

470 Fix gcrypt not properly initialized YAZ-740.
472 --- 5.0.14 2014/02/19
474 Describe memcached option for ZOOM.
476 ZOOM: throw present request out of range again YAZ-739
477 Was removed in YAZ 5.0.13.
479 --- 5.0.13 2014/02/18
481 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
482 with localtime_r when threads + fork is used (such as Metaproxy).
484 yaz-config: quote some RHS values (that might include blanks)
486 zoomsh: shows SearchResult-1
488 zoomsh: sortby command
490 zoomsh: use proper list of connections and result sets YAZ-725
492 Avoid yaz_log in sigterm handler for GFS YAZ-737
493 Logging is still performed, but outside sig handler.
495 New ZOOM C feature: result-set caching with memcached. Example:
496 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
498 Remove SSL via OpenSSL support YAZ-732
499 Also deprecate two functions from comstack that aren't working with
500 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
502 Revert "Bison: use %name-prefix directive rather than -p option"
504 --- 5.0.12 2014/01/22
506 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
508 SRU GET/Solr base URLs may hold additional ?args YAZ-729
509 ZOOM option extraArgs already does this, though. It seems useful
510 when dealing with Solr targets to limit by filter, eg.
511 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
513 Remove #fragment for HTTP request encoding YAZ-730
515 Doc: Update list of DLLs/LIBs
517 Doc: update href link to Unix utils and Git.

521 ZOOM: fix "lost connection" problem with servers that uses both squid
522 and another proxy behind it that returns Location headers with relative
525 zoomsh: do not use readline for stdin (no tty) YAZ-724
526 Just use fgets in that case. If the user hits Ctrl-D a new-line
529 zoomsh: empty command ignored YAZ-723
530 rather than performing exit of zoomsh.
532 yaz-url utility offers option -v to enable verbose mode.
534 yaz_url uses yaz_check_location and offers verbose mode.
536 Add new function yaz_check_location.
537 This function gets an absolute URI from Location (HTTP redirect).
539 cookie API: introduce yaz_cookies_reset
541 Update cql.y for newer bison YAZ-720
542 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
543 longer supported. Instead one must use %lex-param and %parse-param .
545 --- 5.0.10 2014/01/09
547 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
550 rpn2solr: support truncation left(2), left&right(3) YAZ-718
552 Mention SRU version 2.0 in yaz-client man page.
556 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
561 Make cs_parse_host public.A
563 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
564 introduced in YAZ 5.0.6.
568 Fix buffer corruption for yaz-ztest record fetch.
572 Allow yaz-ztest to return user-defined records (one record per file).
573 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
575 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
576 Use the stream write instead of odr_printf which has a 4K tmp buffer.
578 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
582 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
583 can read and write this format. For record format JSON, yaz-ztest returns
584 MARC-in-JSON records.
586 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
587 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
591 Improve error reporting for ICU chains YAZ-707
592 Report config element+rule when ICU status is "failure".
594 ZOOM: stop fetching if present response has no records YAZ-710
595 Some targets return less records than their hit count would suggest.
596 This prevents ZOOM from continuing to fetch records if any present
597 response has 0 records in the response.
599 Ensure that GFS calls exit if any listener fails YAZ-710
600 Before, if XML config was in use, it would start the default
605 yaz-ztest: -V shows version (like yaz-client -V)
607 New iconv encoding: danmarc YAZ-692
609 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
611 daemon: only wait for immediate child rather than all children. YAZ-704
613 yaz-client: fix setting of SRU record schema. If scheme was unset, it
614 could lead to invalid memory reference.
618 yaz-ztest returns schema for MARCXML test records. SRU require that
619 recordSchema for records.
621 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
622 instead of non-surrogate diagnostic. This is a per-record failure.
624 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
625 may refer to multiple listeners now. Attribute listenref is a comma separated
628 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
629 option is given for GFS, the dirname of filename (for -f) is used
630 as prefix for options such as cql2rpn, ccl2rpn, etc.
632 Content-Type charset fixes YAZ-701 . Do not inspect charset in
633 Content-Type header for SOAP when decoding SRU. The payload (XML)
634 itself tells what encoding it is. In response, never supply encoding
635 in Content-Type. The response payload (XML) tells what it is (with no
636 encoding in XML it's UTF-8).
638 HTTP decoding: allow blanks in URL paths YAZ-700
642 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
643 and facets. Ensure recordData and recordSchema are always present in
644 record element, because they are required.
646 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
649 Simplify in a lot of places using odr_strdupn.
651 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
655 Increase various buffers in GFS's statserv_options_block
656 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
657 This change makes many type-casts redundant, and, thus simplifies code.
659 Remove last bits of WAIS support.
661 Remove member 'size' from Odr_oct.
663 Slim down the public part of 'struct odr'. Most elements are not part
664 of struct Odr_private.
666 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
667 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
668 In particular facets are supported in both client - and server side.
669 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
670 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
671 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
672 both request/response). This is what a search handler in the GFS
673 will see (regardless of whether operating in SRU mode or Z39.50).
675 Changes to the srw.h (SRU/Solr) definitions include:
676 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
677 (char*), which replace union query and query_type (int). This is because
678 SRU 2.0 supports a queryType parameter. This also means that, to carry
679 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
680 x-pquery=PQFstring (extention parameter). The extension parameter
682 - New element, packing, that has information about SRU
683 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
685 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
687 New element, packing, in Z_SRW_explainRequest.
689 New elements in Z_SRW_scanRequest, queryType and scanClause.
690 These replace query_type and scanClase untion. This is similar to what
693 --- 4.2.69 2013/10/01
695 GFS: log when closing down - at least SIGTERM YAZ-684
696 Also change formatting WRT PID logging a bit.
698 Improve display of MARC records with multi-byte subfield IDs YAZ-695
699 In some rare cases subfield identifiers are multi-byte characters.
700 This will try to deterime length of those and split accordingly.
701 This affects display in line mode as MARCXML/MarcXchange. The encoding
702 of ISO2709 is the same.
704 Change inp argument to const for yaz_read_UTF8_char.
706 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
708 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
710 Better check of marc leader info YAZ-691
711 Problem is that some systems generate MARCXML/MarcXchange with
712 funny headers. These will not work if encoded as ISO2709.
713 Some tests produce new output, due to updated warning messages
715 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
717 yaz-client: display MAB records YAZ-689.
718 Thanks for Heiko Jansen for this patch.
720 New utility z_get_HTTP_Response_server which allows both HTTP server name
721 and HTTP server URL to be given in response.
723 Debian: do not depend on obs tcl8.3.
725 Debian: do not depend on obs libicu36-dev.
727 --- 4.2.68 2013/09/23
729 GFS: pass additionalSearchInfo to search memeber search_input if
730 given. Otherwise pass otherInfo. Request for facets and other search
731 related things will be passed there in future versions of YAZ.
733 New ZOOM setting, authenticationMode, which allows authentication
734 paramters to be encoded in the URL rather than via HTTP Basic auth.
737 rpn2solr: fix nested AND/OR handling. YAZ-685
739 Add comparison routines for some Z-types, such as NamePlusRecord,
740 RPNQuery, Query, RecordComposition and OtherInformation.
742 --- 4.2.67 2013/09/19
744 Don't decode MAB as MARC. Just like we don't attempt to decode
745 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
747 CCL: allow quoted terms for date ranges. YAZ-681
749 Introduce ccl_parser_qual_search. This function makes old function
750 ccl_qual_search, from YAZ 2, available again.
752 Add yaz_facet_list_to_wrbuf. YAZ-683
754 --- 4.2.66 2013/09/11
756 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
757 schema was given for search. YAZ-675
759 Add Solr date range searches. YAZ-621
761 --- 4.2.65 2013/08/22
763 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
765 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
767 ISO2709/MARC parse most octet aligned records; not just those that
768 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
769 MARC parse more records instead of just dumping as is. YAZ-670
771 ZOOM: proper caching for variations of record schema. YAZ-671
773 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
775 --- 4.2.63 2013/07/17
779 --- 4.2.62 2013/07/11
781 New utility z_get_HTTP_Response_details - an extended version of
784 New utility yaz_url_get_error which returns error message of last
785 failed yaz_url_exec call.
787 yaz-url and url functions: allow max HTTP redirects to be controlled.
789 New functions yaz_file_glob2, yaz_xml_include_glob.
790 These functions takes a flags parameter, which, for now only controls
791 whether to fail inclusion of a non-existing file (without glob
792 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
794 --- 4.2.61 2013/06/20
796 For MARC XML parsing, allow record without leader. A fake/default leader
797 is inserted and a warning is tagged with the record.
799 ICU: fix leak in in icu_iter_get_org_info.
801 --- 4.2.60 2013/06/14
803 ICU: fix bug in icu_iter_get_org_info (un-init variable).
805 --- 4.2.59 2013/06/11
807 Implement z_HTTP_header_remove.
809 --- 4.2.58 2013/06/11
811 ICU: Disallow 0 ptrs for some ICU string utilities.
813 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
814 returns original tokens (before normalization).
816 CCL: avoid z39.58/regex truncation when not needed. Apply only the
817 conversion of those masks, when absolutely necessary.
819 CCL: configurable masking character - @mask. Default masking character
822 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
823 full response anyway, so a Transfer-Encoding header will obstruct the
826 --- 4.2.57 2013/05/15
828 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
829 picking a socket. Problem is that some systems has IPV6 support, but
830 we can't create sockets for them, so we pick AF_UNSPEC first.
832 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
833 use content_len to determine resulting Content-Length in HTTP response
834 and NOT Content-Length supplied in headers by user.
836 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
837 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
839 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
842 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
843 with big endian and unsigned char (by default).
845 --- 4.2.56 2013/04/26
847 Fix yaz-client connect (crash in 4.2.55).
849 --- 4.2.55 2013/04/26
851 Fix proxy/host problem for ZOOM that could occur if unix sockets
854 New Debian package libyaz4-dbg.
856 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
857 differently in tcpip_close.
859 --- 4.2.54 2013/04/17
861 Windows installer of YAZ includes YAZ4J as a component.
863 CQL: allow "extra terms" again, by default. Thus, the CQL parser
864 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
865 and earlier. CQL parser may operate in strict mode where queries
866 not conforming to the standard BNF are rejected (syntax error).
867 Whether the CQL parser operates in strict mode is controlled with
868 cql_parser_strict . Strict mode enabled with option -S for utilities
869 cql2pqf and cql2xcql .
871 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
873 --- 4.2.53 2013/04/10
875 New charset, MARC-8c, which is like MARC-8 but allows control characters
876 0x01 through 0x1F, except ESC to be passed through verbatim.
878 Fix a problem with duplicate sub field character in MARC output. Problem
879 happened only when output was MARC-8 encoded.
881 --- 4.2.52 2013/04/03
883 yaz-ztest: Use hash for fake hit count. Before, random number was used.
884 This is problematic for unit tests using yaz-ztest. This patch also makes
885 a hash for CQL queries. For RPN, any term with a leading digit will be
886 treated as pseudu hit count (to force any particular hit count by a client).
888 yaz-ztest: return unique MARC dummy records. Beyond record offset
889 24, the author surname is patched with offset to make all records
892 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
893 on system wide default (/proc/sys/net/ipv6/bindv6only).
894 @4 binds to IPV4 only. @6 binds to IPV6 only.
896 Update CQL API documentation a bit
898 CQL: don't accept extra terms for queries. Makes the CQL parser
899 stricly conformant to the standard.
901 --- 4.2.51 2013/02/12
903 GFS: scan handler gets extra_args from request and may return extra
904 response data . That's for SRU only.
906 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
908 --- 4.2.50 2013/01/30
910 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
912 OPACXML: sync spelling of availabilityDate in XML to that of Schema
913 opaxxml.xsd. The schema had the correct spelling of this member always.
914 The ASN.1 was mis-spelled and still is (API change) - we are
915 not changing this. However, the OPAC to XML conversion had yet
918 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
921 New function, z_ext_record_oid_nmem, which is similar to
922 z_ext_record_oid but takes NMEM rather than ODR
924 --- 4.2.49 2013/01/18
926 ICU: New conversion element 'join' which joins tokens into one
927 with a custom character given by rule attribute.
929 --- 4.2.48 2013/01/10
931 New GFS search member: present_number. This is a hint to the
932 search handler how many records are going to be fetched immediately
933 following search. There's no guarantee that it's going to be the case,
934 since it depends on hit count (for Z39.50 piggyback) and whether errors
937 Make a few functions static (private). The functions getbyte_stream,
938 ungetbyte_stream and yaz_gets are now private. They were never declared
941 yaz-marcdump: exit(5) for serious decoding errors
943 ISO2709 decoding: be more picky WRT header
945 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
946 was only used as to indicate that next-result-set-position should be
948 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
949 Based on patch from Ashley Sanders.
951 Make some functions static/private in PQF parsing. Those functions were
952 never declared in a public header and so should not be in use by
953 applications based on YAZ.
955 --- 4.2.47 2012/11/23
957 ZOOM: special options to control APDU logging.
958 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
959 logging of APDUs until "saveAPDU" option is set again. If logging is
960 already enabled the effect is that current APDU buffer is cleared.
961 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
962 logging (default behavior on new connection).
963 The APDUs sent/received can be obtained by using
964 Using ZOOM_connection_option_get(c, "APDU") or
965 ZOOM_connection_option_getl(c, "APDU", &l).
967 GFS: relay implementation_version from backend
968 From 3.0.40 and later, implementation_version from backend was
969 not used in init response at all.
971 --- 4.2.46 2012/11/15
973 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
974 mode at all. Probably never did.
976 Make a new version of ztest.pem that, at least, is not expired.
978 --- 4.2.45 2012/11/13
980 Fix description of CCL directive 'case'.
982 More tight checking of form arguments (yaz_uri_to_array). Makes
983 YAZ better at rejecting big and/or bad POSTs.
985 SRU decoding does not report more than up to 10 invalid arguments.
987 rpn2cql: less quotes in generated terms. Semantics unchanged, but
988 it's prettier this way.
990 --- 4.2.44 2012/10/25
992 New utility yaz_decode_init_diag. Defined in proto.h.
994 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
995 given for unix local socket.
996 The COMSTACK string for doing so is:
999 unix:/myfile:tcp:localhost:9999/mybase
1000 unix:/myfile:localhost:9999/mybase
1001 unix:/myfile:http://fakehost/mybase
1003 debian: Use dpkg-buildflags in build process.
1005 --- 4.2.43 2012/10/19
1007 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
1008 global's SRU service uses a recordPosition scheme starting from zero.
1009 First record's position should be one
1010 according to the standard.
1012 --- 4.2.42 2012/10/18
1014 Allow more namespaces for SRU. This is to allow, for example, an
1015 incorrect namespace returned from server
1016 http://services.igi-global.com/sru .
1018 Minor fixes for compilation on Windows.
1020 --- 4.2.41 2012/10/11
1022 daemon: log total number of bad signals from child on stop so that it
1023 is more easy to spot problems with child worker processes.
1025 retrieval: empty backend name attribute omits element set
1026 from being used in retrieval.
1028 --- 4.2.40 2012/10/04
1030 Implement Solr sort strategy "solr", similar to sru11 sorting.
1031 This will implement the correct parameters on Solr requst to do
1034 --- 4.2.39 2012/09/28
1036 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
1039 MARC: Extra/missing indicator handled for MARCXML.
1040 The indicator length is given in header and is the same for the
1041 whole record. If attributes ind1, ind2 are missing, then content
1042 character defaults to blank. Extra indicator attributes (beyond)
1043 indicator length are treated as an error.
1045 Reformat: delete trailing whitespace
1047 --- 4.2.38 2012/09/17
1049 MARC: fix non-ASCII characters for leader. This is to ensure we can
1050 generate XML in UTF-8.
1052 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
1053 in one node with structure word.
1055 --- 4.2.37 2012/09/04
1057 yaz-json-parse: JSON output may be pretty printed by using option
1060 Increase default value of max message for Z39.50 Init for GFS, ZOOM
1061 and yaz-client. Old value was 1 MB. New value is 64 MB.
1063 --- 4.2.36 2012/08/22
1065 yaz-client: don't display bogus records from SRU servers. Some SRU servers
1066 return more records than given by *maximumRecords*. Skipping those in
1069 record_render: simplify buffer return handling and fix at least one bad
1070 memory reference, that broke the test_embed_record sometimes.
1072 Allow http://user:pass@host notation for yaz_url_exec.
1074 zoomsh: allow shell command to be executed. Via the system(3) call.
1076 yaz_poll: Allow num_fds == 0
1078 yaz-client: fix bad encoding of "itemorder item". The itemorder
1079 item <no> - command forgot to use length of encoded Item Request
1080 package. Error present since YAZ 3.
1082 yaz-ztest: fix bad usage of session handle. Bug was introduced when
1083 result sets were saved (271a9c83).
1085 SRU recordPacking: guess record packing in response rather than looking
1086 at the recordPacking element which, OF COURSE, changed semantics in SRU
1089 Decode SRU 2.0 responses. The official namespace for responses, according
1090 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
1091 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
1092 nature.com's server, however, usee namespace
1093 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
1094 we are now using a glob-expr to match up the namespace. ZOOM C and
1095 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
1096 I can not find a single real example showing the "real" namespace in
1097 the documentation from OASIS. The namespace for requests is different
1098 from responses, but this is not added to YAZ yet, when we don't encode
1101 --- 4.2.35 2012/06/26
1103 zoom/record_render: add support for Base64 decoding fo MARC records
1104 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
1105 which will decode base64 + ISO2709 marc-8 encoded material from text node
1108 --- 4.2.34 2012/06/07
1110 Add missing definitions ZOOM_resultset_get_facet_field_by_index
1111 and ZOOM_resultset_facets_names.
1113 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
1116 Change APDU dump printing to avoid long leading blanks. For levels 16
1117 or larger the level is shown and the indentation is truncated but
1118 recursed with modula 8. This makes it still reasonable easy to read
1119 - even for nested BER dumps.
1121 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
1122 return 0 (incomplete package) in case where the BER package was
1123 considered too nested (return value of -2).
1125 dumpber: lines of level 15 are not indented further. Two spaces per
1126 indentation; indentation 15 or more is indented to a fixed indentation
1127 and augmented with a level=<no> indication.
1129 zoomsh: increase max size of command+args
1131 GFS: No limit in RPN buf size in CQL to RPN conversion.
1133 --- 4.2.33 2012/05/09
1135 New function for daemon utility, yaz_daemon_stop .
1137 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
1139 --- 4.2.32 2012/04/25
1141 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
1142 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1144 --- 4.2.31 2012/04/23
1146 YAZ daemon utility relays SIGUSR1 to child process.
1148 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1149 would result in en empty database list - which in turn would result in
1150 encoding failure for search.
1152 Fix reading beyond string in yaz_sort_spec.
1154 --- 4.2.30 2012/04/11
1156 Add two new SRU diagnostics:
1157 236: Access to specified database denied
1158 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1160 Document the very useful ZOOM-C option "apdulog".
1162 CQL to RPN: term may be passed through verbatim. This is enabled with
1163 truncation.cql . The assumption being that the term is already CQL.
1165 --- 4.2.29 2012/03/20
1167 record_conv: leader spec may be given for marc element.
1168 The leader spec is given as attribute leaderspec for element marc.
1169 For example to convert a MARC21 record from MARC-8 to UTF-8:
1170 <marc inputformat="marc" outputformat="marc"
1171 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1173 record_conv: allow user-XSLT params. For example:
1174 <xslt stylesheet="MARC21slim2DC.xsl">
1175 <param name="myparameter" value="myvalue"/>
1176 <param name="otherparameter" value="othervalue"/>
1179 record_conv: fix error handling for missing marc charsets.
1181 CQL: fix extra terms in wrong order.
1183 --- 4.2.28 2012/03/06
1185 record_conv: modify new API for conversion types. The conversion types
1186 may be passed in new functions yaz_record_conv_configure_t and
1187 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1189 Avoid mixed statement/variable declare; fixes compilation with Visual
1192 --- 4.2.27 2012/02/28
1194 Add non-standard SRU diagnostic: 235: "Database does not exist".
1195 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1196 Update SRU to Bib-1 diagnostic maps accordingly.
1198 CCL: add two new diagnostics for unsupported masking. The new
1199 diagnostics are: "Embedded truncation not supported" and
1200 "Single charcacter mask not supported".
1202 --- 4.2.26 2012/02/23
1204 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1206 --- 4.2.25 2012/01/11
1208 Build YAZ for Ubuntu Oneiric.
1210 CCL: allow parantheses for proximity operands. For example CCL query
1211 (a) % (b) is now allowed.
1213 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1214 marked dead, rather then being destroyed. If not, the session memory is
1215 being free'd before the search/scan handler is finished. Also destroy
1216 'request' memory in request_release rather than in various places,
1217 which resulted in leaks from time to time.
1219 --- 4.2.24 2011/12/21
1221 cql_sortby_to_sortkeys: honor sort prefix.
1223 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1224 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1225 The rpn2cql family of functions now always returns quoted CQL terms.
1227 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1229 --- 4.2.23 2011/12/15
1231 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1232 sequence is treated as one. For example, &&a=b&&&c& is identical to
1235 --- 4.2.22 2011/12/05
1237 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1238 APDUs for a connection to a WRBUF.
1240 --- 4.2.21 2011/11/23
1242 Fix cql_sortby_to_sortkeys. Completely broken before.
1244 Make CCL's @truncation work again.
1246 --- 4.2.20 2011/11/09
1248 New ZOOM connection setting: tproxy. It's like proxy, but does not
1249 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1250 to set resolved address + port for a connection outside ZOOM itself.
1252 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1254 --- 4.2.19 2011/11/07
1256 Fix uninitialized variable in Solr spell support (could cause SEGV
1257 for SRU response decoding).
1259 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1260 back-end's addinfo through into the ZOOM response addinfo.
1262 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1263 they are separated by a colon and a space rather than simply
1266 --- 4.2.18 2011/10/28
1268 Add support for Solr spell-checking/suggestions through ZOOM.
1269 If a Solr target has been configured correctly for spelling-checking
1270 and suggestions, these will now be returned on the ResultSet option
1271 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1273 --- 4.2.17 2011/09/28
1275 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1276 with a flag whether to substitute escape sequences or not.
1278 --- 4.2.16 2011/09/22
1280 Fix nmem_strsplit_escape to substitute escape char properly.
1282 New option for zoomsh -e , which makes it abort on first error and
1283 return process exit code to indicate success/failure.
1285 YAZ options utility supports special option -- which makes all it treat
1286 all following arguments as non-options.
1288 --- 4.2.15 2011/09/16
1290 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1291 searched if absolute filename is given.
1293 Fix conv_xslt() error-reporting when stylesheet is not found.
1294 (The value of fullpath is meaningless in this situation.)
1296 --- 4.2.14 2011/09/07
1298 Fix problem in CQL sort node creation: un-initialized memory.
1300 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1301 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1302 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1305 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1306 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1308 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1309 will make it possible to use both single-character mask (#) and wildcard (?)
1310 in CCL . Throw diagnostic for left truncation because that is not supported
1313 --- 4.2.13 2011/09/01
1315 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1316 cases using escapes (\-sequences) and masking.
1318 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1319 would result in a read one byte beyond string.
1321 rpn2ccl may use Z39.50 masking for terms (t=z).
1323 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1325 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1326 not --cppflags (which seeems like an error in icu-config).
1328 --- 4.2.12 2011/08/27 RPM package only
1330 cql2ccl: fix conversion of terms: operator characters were not
1333 --- 4.2.11 2011/08/25 RPM package only
1335 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1336 CCL parser will map both # and ? to their regular expression
1337 quivalents (. and .*).
1339 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1340 of reserved CQL characters.
1342 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1343 is, so that they are passed through.
1345 --- 4.2.10 2011/08/24
1347 ZOOM SRU mode: more aggressive re-connect.
1349 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1350 made available as a utility function, declared in <yaz/logrpn.h>
1352 rpn2cql_structure() supports proximity nodes (except that the Type-1
1353 proximity node's "exclusion" binary is ignored, as there is no way to
1354 express that in CQL). Fixes bug #4564.
1356 --- 4.2.9 2011/08/18
1358 Fix SEGV that could occur if set command of zoomsh was given without
1359 value (2nd argument).
1361 Fix SEGV that could occur if unsupported transport was given for
1362 COMSTACK - say https (when SSL was unavailable).
1364 Build yaz-url on Windows too.
1366 --- 4.2.8 2011/08/11
1368 New utility to get web content. Header is url.h. A command line tool
1369 yaz-url is part of the distribution and packages.
1371 Fixes for SSL COMSTACK (when gnutls is in use).
1373 New functions yaz_base64{encode,decode}. Header is base64.h.
1375 --- 4.2.7 2011/08/03
1377 ZOOM C includes HTTP response buffer as additional info if it fails
1378 to decode the SRU response.
1380 Make wrbuf_json_puts available.
1382 --- 4.2.6 2011/07/28
1384 zoom: throw diagnostic for invalid value for option "sru". Before a
1385 bad SRU request was sent.
1387 Adding new utility wrbuf_vp_puts.
1389 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1391 --- 4.2.5 2011/07/21
1393 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1394 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1395 redirect was used at the same time.
1397 MARC line mode decoding: be less picky about length given - first
1398 5 digits of header that is.
1400 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1402 Changes to decoding of SRU records: a record with recordPacking=xml is
1403 modified with a new root element <yaz_record> if the recordData contains
1404 multiple children elements. This is to make the record XML parseable
1407 RPN to Solr conversion: encode special characters.
1409 Generic Frontend Server: fix uinitialized member, stepSize.
1411 --- 4.2.4 2011/06/21
1413 Fix a bug in SRU decoding of records.. The database records stored
1414 had un-initialized memory, but it would only be seen with yaz_record_render
1415 and type_spec="ext" .
1417 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1419 --- 4.2.3 2011/06/17
1421 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1423 --- 4.2.2 2011/06/10
1425 Add new utilities to convert from CQL to CCL . These utilities have
1426 prefix cql_to_ccl defined in cql.h.
1428 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1429 lead to memory heap corruptions when ICU utilities were in use.
1431 --- 4.2.1 2011/06/07
1433 Make compilation work without Libxml2.
1435 yaz-client: remove redundant blanks in display of searchResult-1 term
1438 --- 4.2.0 2011/05/18
1440 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1441 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1443 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1444 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1445 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1446 Note that the CQL sortby spec is only converted when the GFS is already
1447 converting from CQL to RPN (cql2rpn element).
1449 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1450 specify whether to collapse delimitors or not. The existing nmem_strsplit
1451 do collapse (collapse parameter = 1).
1453 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1455 Rename internal func yaz_use_attribute_create. While non-static, this
1456 function is not declared in a public header.
1458 --- 4.1.7 2011/03/15
1460 Add -lCrun when linking with ICU on Solaris.
1462 More quicks character set conversions for OPAC records.
1464 --- 4.1.6 2011/03/10
1466 fix problem with record_render: records were converted (character set
1467 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1469 --- 4.1.5 2011/03/08
1471 SRU: add methods for handling DADS SRU-proxy facets.
1473 Separate OPAC record character set for ZOOM_record. yaz_record_render
1474 allows a character set given as charset=from/opacfrom,to where 'from' is
1475 the character set of a bibliographic record, 'opacfrom' is character set
1476 of OPAC record and 'to' is the target character set.
1478 --- 4.1.4 2011/02/21
1480 yaz-client: show may XML format records. Command show followed by 'format'
1481 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1484 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1487 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1489 --- 4.1.3 2011/01/27
1490 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1492 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1493 this package can be distinguished from other vendors.
1495 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1496 as determined by configure
1498 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1500 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1501 returns no error and no record, the present request is considered
1502 partial (only a subset of the records could be returned by backend), and
1503 so it is appropriate to set Present Status to partial-4.
1505 --- 4.1.2 2010/11/02
1507 Move yaz-config man pages to section 1.
1509 More documentation about Solr.
1511 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1512 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1513 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1514 peers on some Linux systems. However, in general that does not work
1515 so YAZ can not rely on that to work. Debian changed behavior in this
1516 respect from Debian lenny to Debian squeeze (still testing as of Oct
1518 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1520 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1522 --- 4.1.1 2010/10/05
1524 Fix yaz-config output: echo_source not set correctly by configure.
1526 --- 4.1.0 2010/10/05
1528 Solr Web Service support for yaz-client and ZOOM.
1530 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1532 --- 4.0.12 2010/08/17
1534 Z39.50 facet support. Facet specifications are passed for search in
1535 other-information with ASN.1 as defined in facet.asn and OID
1536 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1537 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1538 3 is limit (number of entries to get in response). yaz-ztest returns
1539 dummy facets if a client asks for them.
1541 --- 4.0.11 2010/07/09
1543 CCL fixes: bug 2895 and bug 3539.
1545 GR1-display: add comma in display - was removed by mistake in
1548 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1550 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1552 --- 4.0.10 2010/06/18
1554 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1555 result set from a connection. The result set will be on its own
1556 thereafter; no operations on it will perform retrievals from a target.
1557 Only cached copies are returned.
1559 ZOOM C:fix case for HTTP servers responding with Connection:close.
1560 Ensure that if there is a current task it is resumed (like fetching
1561 more records in a result set) . Bug #3484.
1563 PQF parser: use odr_atoi for Odr_int (not atoi)
1565 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1566 values that contain any non-digits are treated as string attributes
1567 (previously decoding only checked for leading character ([0-9]). PQF
1568 encoding: attribute string values are not surrounded by double-quotes.
1570 --- 4.0.9 2010/05/21
1572 New utility for managing threads - thread_create.h.
1574 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1575 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1576 but YAZ' implementation do.
1578 Fixes for yaz_cond-functions on Windows 7.
1580 DLL export more symbols.
1582 zoomsh: show record do NOT render opac.
1584 Remove *.la files from Debian and RPM packages.
1586 --- 4.0.8 2010/05/11
1588 Debian package libyaz-dev depends on libgnutls-dev again (was
1589 removed in YAZ 4.0.6, but due to Libtool it is still needed
1590 even though yaz-config do not list libgnutls libs).
1592 ZOOM: Use only one WRBUF for returning string results for
1593 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1595 ZOOM: ZOOM_connection do not use a shared pointer to
1596 ZOOM_resultset after ZOOM_resultset is destructed by
1597 user. Reverts to YAZ 4.0.4 behavior.
1599 --- 4.0.7 2010/05/04
1601 record-conv: fix problem with at least one XSL conversion -
1602 due to probably incorrect usage of XML XSL documents.
1604 --- 4.0.6 2010/04/29
1606 Fix yaz-config for static mode and the use of SSL (gnutls).
1608 --- 4.0.5 2010/04/29
1610 Forward decl timeval struct in mutex.h and gettimeofday.h.
1612 yaz-config: fix 'static' mode linking.
1614 --- 4.0.4 2010/04/28
1616 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1617 are wrappers for pthreads or Windows. For Windows these are put in
1618 a separate DLL: yaz_cond4.
1620 libyaz.la (whole source) is compiled with thread. If thread support
1621 is enabled enabled, all source of YAZ is compiled with treading support.
1622 This allows core utilities such as yaz_log to use thread facilities.
1623 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1624 thread utilities. This commit moves mutex utilities (mutex.c) from
1625 libyaz_server.la to libyaz.la.
1627 yaz-json-parse displays leading text until error.
1629 --- 4.0.3 2010/04/09
1631 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1632 patch from Giannis Kosmas.
1634 SRU: no longer URL encode SRU database. The URL for an SRU server is
1635 a URL and such is alreeady encoded - at least when given with leading
1636 http:// or https://. This reverts behavior to YAZ 3.0.50.
1638 Support for new MARC XML notation TurboMARC which like MARCXML is a
1639 complete representation of MARC/ISO2709.. This one, however, is more
1640 compact and allows for faster processing with XSLT. TurboMARC can be
1641 used in the marcdisp.h API, from the yaz-marcdump utility and from
1644 yaz-ztest can be configured - via the database - to perform certain
1645 delays when it performs operations search, present and single record
1646 fetch. This allows testers to make yaz-ztest act as a real or even slow
1647 Z39.50 server. Refer to the yaz-ztest man pages for details.
1649 --- 4.0.2 2010/03/09
1651 wrbuf_destroy allows NULL WRBUF passed to it.
1653 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1655 Add ZOOM_connection_close.
1657 No fixed size buffers for ZOOM shell - bug #3257.
1659 tstodr: make it work on s390 platform.
1661 New icu iterator-functions. The new icu_iter-functions makes it possible
1662 to use ICU chains from many threads.
1664 yaz-client: better syntax check for show command.
1666 --- 4.0.1 2010/01/26
1668 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1671 New simple local-file XML include facility which allows file glob-patterns.
1672 Refer to yaz/xml_include.h.
1674 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1677 ZOOM_record_get supports new parameter "format" which makes it format XML
1680 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1681 JSONText in ECMA-262) is JSONValue, not JSONObject.
1683 --- 4.0.0 2010/01/20
1685 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1686 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1688 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1689 POSIX/Unix builds .so with major version 4.
1691 Remove old LOG_-defines from log.h. They have been obsolete and
1692 undefined by default for the last 5 years.
1694 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1696 GFS: Remove socket (int *fd) from search_rr handler. The socket
1697 descriptor ptr is a facility that allowed a search handler to supply
1698 a socket which would serve as a callback - when search was complete.
1699 This facility has now been in use for years.
1701 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1702 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1703 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1704 returns 'const char *' rather than 'char *. The returned string is
1705 read-only and should not be modified by applications. COMSTACK cs_close is
1706 now a void function - it no longer returns int. No applications check for
1707 the value and the implementations has always returned 0.
1709 ZOOM: use size_t for scan hit counts and str size. Functions
1710 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1711 occ (hit count) and len (string length) are now of type size_t pointer
1712 rather than int pointer. This is to be able to represent large hit counts
1713 and to also just to use the proper type for string length (strlen result).
1715 New JSON parser. Refer to include/yaz/json.h .
1717 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1718 Used to be int in some cases. Many wrbuf_-functions used to return an int
1719 indicating some length.. These return values were never used. And so they
1722 ODR: odr_malloc, odr_total now takes size_t for size.
1724 clone_z_type: fix leak; occurred for encoding failures.
1726 --- 3.0.52 2009/12/03
1728 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1729 bug was introduced in 3.0.51.
1731 --- 3.0.51 2009/12/02
1733 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1735 tcpip comstack: fix leak for getaddrinfo.
1737 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1738 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1739 Decoding of SRU "path" database is performed by private function
1740 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1741 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1743 yaz-client: honor base command for SRU. Change when database setting
1744 is applied for SRU and ensure it is kept when a connection is reset.
1745 Change also the way errors are displayed or SRU (decoding of packages).
1747 --- 3.0.50 2009/11/02
1749 Add support for extra request / response data for SRU codecs and GFS.
1750 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1751 for extra data response buffer and length. For the GFS, both request
1752 and response data (XML) is carried in extra_args and extra_response_data
1753 for the search handler. Patch by Ko van der Sloot.
1755 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1756 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1757 10010). This fixes bug #2113.
1759 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1760 cmdfile included a 'quit' command that would result in a memory violation.
1762 --- 3.0.49 2009/10/01
1764 Make a number of functions defined in xmlquery.c static. These have
1765 never been declared in a public header file (yaz/xmlquery.h) and was
1766 made public by mistake.
1768 Improve speed of character conversions (iconv utilities). This makes
1769 conversions from MARC-8 faster.
1771 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1772 unless type desired is "raw". This will prevent type "xml" from
1773 returning ISO2709 .. Which obviously can not be XML parsed.
1775 Fix memory leak in ZOOM that would occur if option apdulog was used
1776 on a re-used connection.
1778 Frontend server logs HTTP requests.
1780 Frontend server now sends Z39.50 close when it times out (sesssion has
1781 been idle for too long). Versions 2.0.30 and earlier also sent close.
1782 But due to a mistake this was disabled in all versions after that, i.e.
1783 the server would just close the socket immediately.
1785 yaz-client emits a better message when receiving an unrecognised
1786 userInformationField.
1788 Skip zero-length subfields when decoding ISO2709. This rare case happens
1789 if a record has two FS characters in a sequence. Without this patch
1790 there would be a reference beyond char array in using_code_len fragments
1793 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1795 --- 3.0.48 2009/08/28
1797 The show command offered by the zoomsh command now takes a 3d optional
1798 parameter type which is what is passed to ZOOM_record. If the type
1799 argument is omitted, "render" is used.
1801 RPN to CQL conv may use USE string attributes (bug #2978).
1803 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1805 --- 3.0.47 2009/07/08
1807 Function yaz_xml2query allows a diagnostic element in the PQF XML
1808 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1809 code and additional info respectively.
1811 The BER BOOLEAN is now the integral type Odr_bool which still happens
1812 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1813 typedef'd to Odr_int. This is still an integral 'int', but it may be
1814 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1815 ASN-1 compiler as well as programs has been updated to use the new types.
1817 --- 3.0.46 2009/06/08
1819 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1820 only the bibliographic record was rendered. For type=opac, an OPAC
1821 record is only returned if it is present.
1823 iconv: small fix for encoding of advancegreek.
1825 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1827 yaz-client: option auto_reconnect=on really reconnects.
1829 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1831 server: avoid null ptr ref for for yaz_poll errors.
1833 build: fix RPM build for RHEL 5.3.
1835 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1837 --- 3.0.45 2009/03/31
1839 Fixed bug #2709: TCP connect returns Invalid argument.
1841 Fixed compilation for mingw.
1843 Honor charset for raw records (ZOOM_record_get).
1845 Fixed use of errno for threaded mode that was seen on Solaris 10.
1847 Fixed argument passing with blanks in value for Windows Service.
1849 Disable YAZ' own log rotate by default (no 1 GB limit).
1850 The variable l_max_size which specifies the log file limit is set to 0
1851 (DISABLED): This is due to the fact that YAZ is most often deployed using
1852 logrotate. Also YAZ can not perform log rotate because of unsufficient
1853 permissions (setuid).
1855 --- 3.0.44 2009/02/17
1857 List supported encodings in man page for yaz-iconv.
1859 Fixed missing SSL libs for --libs output
1861 Re-established OID record syntax application-xml. Nobody should use it
1862 but we don't want to change soname because of this symbol being absent.
1864 --- 3.0.42 2009/02/02
1866 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1868 Added member named_result_sets for init handler struct for the GFS. This
1869 allows a server to disable named result sets.
1871 Removed OID record syntax application-xml.
1873 Added support for rule-based transliterator for ICU wrapper of YAZ.
1875 Fixed bug #1902: yaz-icu XML output.
1877 Make YAZ checks Emacs friendly.
1879 BITSTRING value shows value. Bug #2346.
1881 ISO2709 decoding: skip control characters from indicator data.
1883 Omit sort key by default in yaz-icu's output.
1885 Allow combined single char options (again) for YAZ' options function.
1887 Utility yaz-marcdump got option to display YAZ version (-V).
1889 Allow YAZ to use ICU 3.4.
1891 Added new ICU test case which illustrates removal of diacritics.
1893 --- 3.0.41 2008/12/29
1895 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1897 --- 3.0.40 2008/12/29
1899 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1902 Fixed bug #2352: yaz-marcdump crashes for certain record.
1904 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1906 Added support for Danmarc2 to UTF-8 conversion.
1908 Added support for ISO5426 to UTF-8 conversion.
1910 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1911 implementation version.
1913 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1915 --- 3.0.38 2008/11/10
1917 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1918 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1920 ZOOM C now interprets databaseName option for ZOOM connection as path
1923 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1925 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1927 Dummy Libxml2 types no longer defined in headers of YAZ'.
1929 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1932 --- 3.0.36 2008/09/26
1934 Various ODR chapter fixes.
1936 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1938 Added missing source for Windows compilation, mutex.c.
1940 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1942 For SRU connections in ZOOM all records up to "count" are now fetched.
1944 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1945 in Windows due to bad error handling for Libxml2.
1947 Added facility for sending arbitrary records (ASN.1 any) using
1948 ZOOM C's Extended service update. Patch by Sam Reynolds.
1950 New options for ZOOM C's connection, logapdu which makes ZOOM log
1953 --- 3.0.34 2008/06/18
1955 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1957 --- 3.0.32 2008/06/12
1959 Fixed memory violation that could occur when decoding UTF-8. This bug
1960 was only present in 3.0.30 of YAZ.
1962 --- 3.0.30 2008/06/06
1964 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1965 GNU TLS is used by default (if found).
1967 yaz-ztest returns OPAC records if a client asks for OPAC.
1969 Improved speed of MARC-8 encoding.
1971 Added support for lossy and loss-less MARC-8 encoding.
1973 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1975 Added new Windows Service wrapper (sc).
1977 yaz-client's itemorder command may now send a file.
1979 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1981 Added new function yaz_log_xml_errors.
1983 Allow (but warn) unknown XML attributes in MARCXML parsing.
1985 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1987 The UTF-8 to MARC-8 conversion now uses a different set of characters
1988 for Greek symbols. Bug #2120.
1990 --- 3.0.26 2008/02/21
1992 Added yaz_daemon (daemon.h).
1994 Fixed bug #2068: pkg-config trouble
1996 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1998 --- 3.0.24 2008/01/28
2000 Document --with-xml2 option.
2002 Added OPAC XML XSD (etc/opacxml.xsd).
2004 Allow glob mask for name attribute in retrieval element for the
2005 generic frontend server's retrieval facility.
2007 Changed yaz_poll_poll to return yaz_poll_except for all returned events
2008 except POLLIN/POLLOUT.
2010 Fixed error handling in cs_listen. Bug #2037.
2012 --- 3.0.22 2008/01/20
2014 Fixed version in yaz/yaz-version.h.
2016 Fixed bug #2027: Crash when closing connection.
2018 Changed configure so that ICU support is only enabled if only ICU
2019 and Libxml2 is available (because the ICU chain is XML based).
2021 --- 3.0.20 2008/01/15
2023 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
2024 is built. Only this DLL depends on the ICU runtime.
2026 yaz-ziffy is no longer part of YAZ. It is distributed separately by
2027 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
2029 Changed license of CCL module to 'Revised BSD'. After consultation with
2030 remaining members of the original EUROPAGATE consortium, we are re-issuing
2031 the CCL module without a separate license. The software was developed by
2032 Index Data as part of a research project. The special license was included
2033 to help feed usage information back to the project consortium to support
2034 project evaluation. At this time, the project consortium has long-since
2035 disbanded, and the majority of the original principals have retired. At the
2036 same time, we have significantly modified the software during the following
2037 years, to the point where very practically no original code remains. To
2038 simplify re-use of the software, we have contacted those members of the
2039 consortium who could be reached, and agreed to re-issue the module as a
2040 proper part of the YAZ package.
2042 Tcl scripts uses /usr/bin/tclsh as preferred shell.
2044 CQL closer to being version 1.2 compliant. CQL also allows free-form
2045 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
2048 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
2049 bug could make Extended services handling crash in the ZOOM layer. This
2050 bug was only present in YAZ 3.0.18.
2052 --- 3.0.18 2007/12/19
2054 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
2057 yaz-marcdump reads and writes collection wrapped records.
2059 Handle OPAC for record conversion module.
2061 Fixes for ICU wrapper.
2063 Allow ICU libs to be controlled with --with-icu .
2065 --- 3.0.16 2007/11/12
2067 Added yaz_poll which is a wrapper for select/poll. When poll is available
2068 and non-buggy, it is used, by yaz_poll . This allows more than 1024
2069 sockets to be in use.
2071 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
2072 functionality through an XML based configuration (ICU chain). This system
2073 is useful for search facilities such as Pazpar2 and Zebra that needs to
2074 perform tokenization of indexed material. The ICU code in a separate
2075 library libyaz3_icu.a.
2077 Added HTTP tunnel facility for COMSTACK, bug #1752.
2078 This is a facility that allows a Web proxy, such as squid, to tunnel
2079 Z39.50 traffic. This facility is "transparent" to must applications
2080 using YAZ. It's enabled by using pseudo transport connect: followed by
2081 the proxy address, followed by command, then follwed by he regular
2082 "virtual" addresss. For example,
2083 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
2085 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
2087 --- 3.0.14 2007/09/21
2089 Fixed bad memory reference in ZOOM_record - cuased by member not being
2090 initialized. This was a problem only in YAZ 3.0.12.
2092 Fixed bug in conversion from MARC to XML: Non-XML characters in control
2093 fields were not removed.
2095 Changed the way C code is generated from codetables.xml. Made a MARC-8
2096 conversion trie for each characterSet section rather than codeTable.
2097 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
2098 of codetables.xml from Larry Dixson, LOC. Bug #1464.
2100 --- 3.0.12 2007/09/12
2102 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
2103 from ZOOM_record_error).
2105 ZOOM C function ZOOM_record_get returns record schema for type="schema".
2107 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
2109 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
2111 Better SRW-to-Bib-1 diagnostic mapping.
2113 ZOOM C and yaz-client announces SRU version 1.2 by default.
2115 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
2118 Fixed in yaz_sru_decode to allow other version than 1.1.
2120 --- 3.0.10 2007/08/22
2122 Added support for SRU scan for ZOOM.
2124 Added support for the use of the older versions or Extended Service
2125 Update in ZOOM. To faciliate this, an option "updateVersion" may be
2126 set to the version , 1=first, 2=second, 3=third. The third version is
2127 what ZOOM C has used so far. And that, obviously, is the default.
2129 Added support for CCL queries in Z39.50 queries sent to the GFS (and
2130 therefore in Zebra and in SimpleServer-based applications). The new
2131 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
2132 qualifier file used to transform incoming CCL queries into Type-1 RPN,
2133 which is passed into the back-end search callback function.
2135 Added support for HTTP Basic authentication in clients: the SRU/W
2136 codec encodes the username/password elements of the PDU structure
2137 appropriately, and these may be set using the "user" and "password"
2138 options in ZOOM-C applications (the same options that are used for
2139 Z39.50 authentication).
2141 --- 3.0.8 2007/06/25
2143 Fixed bug #1208: SSL appears to be broken in ZOOM.
2145 Fixed bug #1206: Libxml2 include path weirdness.
2147 Added oid_name_to_dotstring.
2149 Allow elementSetName to be specified for ZOOM C record update.
2151 Allow waitAction to be specified for ZOOM C based for Extended Services.
2153 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2154 syntax OID. Bug introduced in YAZ 3 series.
2156 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2158 --- 3.0.6 2007/06/06
2160 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2161 directory. yaz-client now reads commands from file given by option -f
2162 if specified; then tries to read .yazclientrc in current directory.
2163 Failing that, it reads .yazclientrc from user's home directory.
2165 Added support for correlationInfo Note and ID for Record Update via
2168 Added yaz-client command querycharset which specifies character set for
2169 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2170 (termListAndStartPoint).
2172 Charset ISO5428:1984 is an alias for ISO5428-1984.
2174 Implemented a way to perform scan in a result set using Z39.50. This
2175 is achieved by attaching the result set name in the characterInfo
2176 (type InternationalString) of OtherInformation in the Scan Request PDU.
2177 The result set is identified in the otherinformation by the new OID:
2178 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2179 This allows for scan in result set and faceted search . Zebra did some
2180 of this in the APT term using attribute type 8 and value being result
2181 set. Using the OtherInformation approach for this is cleaner and easier
2182 to work with in proxies and the like. This facility can be used in
2183 yaz-client using new command setscan which takes a result set as first
2184 argument, start position (APT) as second.
2186 Changed decoding of SRU XML packed records to deal with servers that
2187 have recordData with XML data with multiple root nodes. Also make
2188 comparison for recordPacking case insensitive. Again, one server
2189 returns "XML" where others return "xml".
2191 For SRU responses allow Content-Type application/xml as well as text/xml.
2193 --- 3.0.4 2007/05/21
2195 Fixed bug in character set conversion of BER strings. Bug introduced
2198 --- 3.0.2 2007/05/08
2200 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2202 For OID class, use oid_class consistently.
2204 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2207 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2208 character set for bibliographic information interchange". By Giannis Kosmas.
2210 Added documentation on new OID API.
2212 --- 3.0.0 2007/05/02
2214 Changes to generic frontend server interface: added new member
2215 'query_charset' for bend_initrequest structure. A backend init handler
2216 should set this member to its native character set for query terms.
2217 When defined, the frontend server logic will announce this character set
2218 to a client if the negotiationModel bit is set by the client. All server
2219 implementors are encouraged to specify this. If a backend server does not
2220 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2222 Added CCL utility to remove terms (stop words) from resulting RPN
2223 tree. This is handled by functions with prefix ccl_stop_words_ .
2225 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2226 terms in RPN queries.
2228 Clean-up the CCL API. Moved some internal structures from ccl.h to
2229 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2230 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2231 This is replaced by ccl_parser_find_str which takes a string instead.
2233 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2234 libyaz.la is the core of YAZ except the generic frontend server and
2235 does not depend on POSIX threads anymore. libyaz_server.la is the
2236 generic frontend server facilities and uses POSIX thread functionality
2237 if available. The libyaz.la no longer depends on POSIX threads because
2238 the number of global structures is limited. NMEM no longer re-uses blocks
2239 between threads ; it simply free's memory immediately but allocates in
2240 "large" chunks as usual. We don't expect any performance penalties
2241 because of this. The yaz_log system is still using a global log_level so
2242 caution must be taken when modifying it with yaz_log_init_.. +
2243 yaz_log_mask_str. This, however, should not cause any trouble because
2244 these functions are called during initialization of application code
2245 anyway. `yaz-config --libs server` returns libs for server applications;
2246 `yaz-config --libs` returns libs for non-server applications.
2248 New OID database - with public definitions in oid_db.h. Removed old OID
2249 database including the head oid.h and definitions such as enum oid_value
2250 and struct oident. The new OID database uses the same string names as
2251 before but the 'protocol' is gone. There are now only two representations
2252 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2253 converts from string to OID; functions with prefix yaz_oid_to_string
2254 converts the other way.
2256 Change to emit_term() in CQL-to-PQF query translation: when a term has
2257 the /regexp relation modifier, do not process it for leading and
2258 trailing "^" and "*", which have quite different meanings in regular
2261 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2262 write handlers no longer carries a 'last' parameter. This will make
2263 yaz_iconv flush "less" characters. A flush is performed by call to
2264 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2266 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2267 removed, because function yaz_query_to_wrbuf does the same.
2269 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2270 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2272 Deprecated MARC utility functions removed.
2274 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2277 Branch split: YAZ_2_1_55_branch
2279 --- 2.1.54 2007/03/16
2281 Fix to ZOOM-C so that transparent reconnection is properly handled on
2282 connections that are in asynchronous mode.
2284 Fixed compilation on OpenBSD 4.0.
2286 Large strings in GRS-1 records are now properly displayed in yaz-client.
2288 Added character conversion support for "advancegreek"; based on patch from
2291 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2292 sequence is met. Before the error was not set so it would be unknown.
2294 Adjust yaz-marcdump MARC reader so that it skips until record separator
2297 --- 2.1.52 2007/03/07
2299 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2300 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2301 fd_set structure used as a bitmask for the FDs to be selected on.
2303 Using ACX_PTHREAD macro to check for POSIX threads.
2305 Fixed have-vsnprintf check.
2307 --- 2.1.50 2007/02/23
2309 Fixes for configure on BSD. Bug #900.
2311 Added snprintf/vsnprintf wrappers for systems that don't have
2312 limits (heavens forbid).
2314 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2315 created before all previous tasks were completed and removed from the
2316 task queue, the new task could be removed by a mistake.
2318 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2320 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2322 Fixed bug #832: Problem with MARC/charset in yaz-client.
2324 Fixed bug #668: save command line history for yaz-client.
2326 Fixed bug #830: pkg-config support.
2328 --- 2.1.48 2007/01/23
2330 Extended ZOOM result set options with two options that may be read by
2331 a client: resultSetStatus and presentStatus with values as specified for
2333 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2335 Fixed bug #827: Using SSL fails on Debian etch.
2337 Fixed bug #826: Weird looking chars for set of MARC records.
2339 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2340 that is treated as an ItemOrder with itemRequest being an XML document
2341 external. The value of "doc" is the content.
2343 Extended the GFS search facility. New member of bend_search_rr
2344 'estimated_hit_count' signals that hits is known to be an estmate
2345 (higher or lower than real hit count). New member 'partial_resultset'
2346 signals that the search was partial (hit count is lower or equal than
2347 real hit count). For Z39.50, the information is stored in resultSetStatus
2348 member of SearchResponse APDU. For SRU, the information is signalled
2349 via SRU diagnostic 59: "Result set created with valid partial results
2352 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2354 --- 2.1.46 2007/01/13
2356 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2358 Added ZOOM_connection_peek_event.
2360 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2361 the following new functions:
2362 ZOOM_event_nonblock, ZOOM_connection_process,
2363 ZOOM_connection_get_{socket,mask,timeout},
2364 ZOOM_connection_fire_event_{timeout,socket}.
2365 The existing blocking event handler, ZOOM_event, is a wrapper for the
2366 + blocking ZOOM_event_sys_{poll,select}.
2368 Implemented function ccl_xml_config which parses XML version of CCL
2369 configuration (bug #798).
2371 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2373 Added timings utility (yaz/timing.h)
2375 --- 2.1.44 2007/01/03
2377 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2380 Fixed bug #779: Rotation of apdu.log fails.
2382 Fixed for character set conversions:
2383 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2384 Honor G1 set in MARC-8 decoding.
2386 --- 2.1.42 2006/12/17
2388 Fixed bug #775: char conversion does not handle Alternative UTF-8
2391 Implemented function yaz_marc_read_line which parses MARC line format
2392 records. There is a wealth of formats out there. So far, this function
2393 reads line records produced by yaz_marc_write_line.
2395 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2396 more generic and easier to remember(!) options: -i format and -o format
2397 which specifies input format and output format respectively - where
2398 format is one of "marc", "marcxml", "line", "marcxchange".
2400 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2401 does not print anything except warnings for records.
2403 For yaz-marcdump, added support for MARC split into files (-s) with a given
2406 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2407 spec, at http://www.loc.gov/standards/sru/record-update/
2408 This has changed the binary layout of the following structs:
2409 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2410 bend_update_rr . Patch by Ko van der Sloot.
2412 Added GFS utility function bend_assoc_is_alive which returns 1 if
2413 association is still alive (client is connected); 0 otherwise (client
2414 closed connection). This allows busy servers to stop working for
2417 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2418 been a separate piece of software. This version of ziffy has been modified
2419 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2421 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2423 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2424 Client code may now interrogate options such as "init_opt_sort" to
2425 find out whether the server claims to support various options.
2427 --- 2.1.40 2006/11/27
2429 Added utilities yaz_{set,get}_esn to set/get element set name from
2432 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2433 of YAZ and has been so since YAZ 2.1.10.
2435 Implemented ZOOM_record_error which returns error information for
2436 record (surrogate diagnostic).
2438 --- 2.1.38 2006/10/31
2440 Updates for SRU Update by Ko van der Sloot:
2441 1. Changed name from "operation" to "action"
2442 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2443 versions in the code, marked as 'backward compatible'.
2444 3. Added diagnostics for SRU Update.
2446 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2448 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2450 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2452 For GFS, fixed problem with SRU diagnostic 'First record position out of
2453 range' being issued for 0 hits.
2455 zoomtst10 part of Windows Build.
2457 --- 2.1.36 2006/10/13
2459 Implemented yaz_filepath_comp which splits a path into file path
2460 components (required by Zebra 2.0.3+).
2462 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2463 BSD inspired license until now so this should not have any real impact on
2464 anybody. See http://www.opensource.org/licenses/bsd-license.php
2466 Fixed bug #687: Missing log lines.
2468 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2471 Fixed bug #689: SRU diagnostics to be added.
2473 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2474 whether a connection is idle (no more work do do).
2476 --- 2.1.34 2006/10/04
2478 Change type of optval from long to int for invocation of setsockopt with
2479 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2481 Added support for specifying the max log file size for the Generic
2482 Frontend Server. The size is given with option -r.
2484 --- 2.1.32 2006/09/21
2486 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2488 --- 2.1.30 2006/09/17
2490 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2493 Fixed bug in Generic Frontend Server that could cause a server to stop
2494 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2496 For the generic frontend server, the maximum record size is used as maximum
2497 size of incoming packages (SRU + Z39.50). The value until was previously
2498 only used in Z39.50 Init negotiation and, later, in a session controlled
2499 sizes of records returned. This is controlled using -k option. It can be
2500 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2502 --- 2.1.28 2006/09/04
2504 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2507 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2509 New option for yaz-marcdump -lpos=value which allows setting a portion
2510 of MARC header to a certain value.
2512 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2514 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2515 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2517 --- 2.1.26 2006/08/15
2519 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2522 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2524 --- 2.1.24 2006/08/08
2526 Fixed MARC ISO2709 encoding routines to deal with character set
2529 Minor changes to GFS logging. Database included in search request log
2532 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2533 cached/multiple records.
2535 Shared libraries are built by default on Unix+configure.
2537 Changed cql2pqf transformation to use a different evaluation order. The
2538 new order is: always, relation, structure, position, truncation, index
2539 and relationModifier. Old order was: always, relation, relationModifier,
2540 structure, index, position, truncation. Note that the the latter ones
2541 override former ones for identical attributes.. The new scheme means that
2542 it is possible to override any existing attribute with a relationModifier.
2543 And also that it is possible to override everything for the index rule
2544 (except the ones listed in relationModifier). No order is perfect but this
2545 one, we believe, covers more real cases.. The "always" should have been
2546 called "default", since the attributes there can be overridden with all
2549 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2550 compilation phase, but also for yaz-config --cflags output. This allows
2551 us to have public headers with Libxml2 stuff in them . It should also,
2552 eventually, make Libxml2 checks redundant in packages using YAZ, such
2555 --- 2.1.22 2006/06/15
2557 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2558 stored in uri, message and details.. Previously diagnostics were stored
2559 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2560 compatibility.. but he's probably the only one affected, so.
2562 Added support for CCL, compiled on the client side, in ZOOM-C. This
2563 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2564 input; the resulting query objects can be used for for searching with
2565 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2567 YAZ' configure searches for OpenSSL by default.
2569 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2570 SL_CTX_use_certificate_file. See
2571 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2572 for more info. Thanks to Ko van der Sloot.
2574 --- 2.1.20 2006/06/02
2576 Bug #600: SRU GET, POST support for yaz-client. Introduced
2577 command 'sru' which selects method SOAP/GET/POST.
2579 Allow missingValueAction to be specified for the sortspec string -
2580 function yaz_sort_spec. By default, the missing value action is null.
2581 Use ! to specify "abort". Use = followed by stringvalue to specify default
2584 Ensured that Present-handler (if defined) is called in GFS before any call to
2585 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2586 searchRetrieve requests.
2588 Documentation for YAZ is now based on the Docbook XML/XSLT using
2589 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2590 is no longer depending on jade/openjade or docbook-to-man scripts.
2591 PDF is no longer part of the distribution - but can optionally be
2592 made using DSSSL/jadetex or FOP.
2594 Added retrieval handling support in Generic Frontend Server to support
2595 conversion between MARC/XML as well as XSLTtransforms. See
2596 etc/yazgfs.xml for an example.
2598 Added Authentication support to Generic Frontend Server in SRU
2599 mode. Authentication using HTTP Basic is supported, as is the use
2600 of 'x-username' and 'x-password' parameters in the request itself.
2602 Added support for a new character set MARC8s identical to MARC8 except
2603 that it converts combined characters to single Unicode characters in the
2604 Latin-1 range (when possible).
2606 --- 2.1.18 2006/04/24
2608 ASN.1 compiler 0.4: generates brief Doxygen file header for
2609 generated .h/.c files.
2611 Utility yaz_iconv now supports conversion to MARC-8.
2613 New facilities for the MARC module. The reading - and writing of
2614 content are separate methods for the yaz_marc_t handle. The following
2615 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2616 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2617 format). Write functions have prefix yaz_marc_write_.. The existing
2618 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2619 available. Removed support for OAI-MARC and simplexml (not the
2620 simplexml from PHP5).
2622 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2623 to be returned for this connection.
2625 --- 2.1.16 2006/03/31
2627 Allow multiple languages and charsets to be specified with
2628 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2629 negcharset iso-8859-1,utf-8
2631 Translation of proximity nodes from CQL into PQF now works.
2633 Moved to automake 1.8, 1.9.
2635 Added function yaz_log_set_handler which allows a log handler to be
2636 installed. This handler will be called for all log messages. Output
2637 to file is also produced; but that can be disabled by passing NULL
2638 fname to yaz_log_init_file.
2640 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2642 For SRW (including GFS), accept application/soap+xml as content-type
2645 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2646 produces NO stylesheet reference even if a default stylesheet is specified
2649 --- 2.1.14 2006/03/14
2651 Updated Windows package to include yazd.dll + yazd.lib for the
2652 Development component.
2654 If the environment variable YAZ_LOG is set, then it is used as a
2655 string indicating the default level of logging to use if not
2656 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2657 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2658 used as before. So, for example, to omit warnings from YAZ logging,
2659 export YAZ_LOG=-warn
2661 cql_transform() now map structure and other attributes before indexes,
2662 so that index-specific structures and other attributes can override
2663 defaults. So now a combination of mapping specifications such as:
2665 index.dc.date = 1=date-modified 4=5
2666 does the right thing.
2668 cql_transform() now also respects the "always" mapping specification,
2669 which establishes an initial set of attributes to be used for all
2670 terms except where overridden by more specific attributes associated
2671 with the index, relation or modifier.
2673 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2674 which mode to use; one of "post", "get" or "soap" (SRW, default).
2676 Fixes for yaz_iconv routines: changed trie-based character set conversions
2677 to use only non-negative values for bit fields due to Sun's C compiler not
2678 supporting negative values.
2680 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2681 sequences where not read correctly. Fix by Rustam Usmanov.
2683 Updated win/makefile to use options, settings which makes things
2684 compile with VS C 2005.
2686 --- 2.1.12 2006/02/01
2688 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2690 In ZOOM socket code, use select instead of poll on MacOSX.
2692 ZOOM-C now support client-side compilation of CQL into RPN that is
2693 sent to the server, enabling CQL to be used against all Z39.50
2694 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2695 ZOOM_query object, and submit it using ZOOM_connection_search().
2696 The CQL-to-RPN translation uses a configuration file, the name of
2697 which must be specified in the Connection's "cqlfile" option.
2699 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2700 function, which takes as its start-term parameter a ZOOM_query object
2701 (which may have had either CQL or RPN set into it).
2704 --- 2.1.10 2005/11/29
2706 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2707 GFS to support this as well. Backend handler, bend_srw_update, does the
2708 update work. Code contributed by Ko van der Sloot.
2710 Allow retrieval of Search Result-1 information in ZOOM by the use of
2711 options that are attached to a result set. ZOOM documentation updated
2714 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2715 UTF-8 conversion. Patch by Raj Patel.
2717 Added option -m to GFS to control formatting of timestamps in log file.
2719 Added 'exit' as synonym for 'quit' in yaz-client
2721 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2722 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2723 for the new members. Patch by Ko van der Sloot.
2725 Added support for SRU POST. It is supported for content-type
2726 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2728 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2729 Instead make the library libyaz.la multi-threaded. Threading as a whole
2730 can still be disabled by configure option --disable-threads. Previosly,
2731 with older GLIBCs there were problems with MT libs under Apache. This
2732 has now been fixed a long time ago.
2734 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2737 CQL module modified to be case insensitive for relations/indexes/operations.
2739 Fixed bug in CQL transform code: incorrect value relationModifieder
2742 Added 'show all' command for yaz-client which retrieves all results
2745 Added new yaz-client, xmles, which takes a (private) OID and
2746 a document to be sent as an extended service request.
2748 Describe new yaz-client commands wait_response and set_auto_wait.
2750 Increase TCP/IP listener backlog from 3 (which I am guessing was
2751 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2752 that the socket will queue as many incoming connections as it's able
2753 to handle ongoing connections. In other words, it will never now
2754 refuse a connection that it would be able to handle merely because
2755 it's not got around to accepting() enough of the pending connections
2756 yet. This is the behaviour anyway under Linux, where the listen()
2757 argument is ignored; but not under BSD and on systems such as
2758 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2759 YAZ-based servers should now be uniform across operating systems in
2762 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2763 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2764 This allows yaz-marcdump to read large MARC batches (>2 GB).
2766 Modified all YAZ source files - except the source which is auto-generated
2767 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2770 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2771 corresponding to the existing *_setl() function. These allow option
2772 values containing arbitrary valuues.
2774 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2775 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2776 except that it returns an indicator of whether or not the sort
2777 criterion was accepted (0 for OK, -1 for invalid).
2779 --- 2.1.8 2005/06/07
2781 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2782 MARC output rather than returning "new" buffer.
2784 yaz-client warns about unknown init options.
2786 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2788 --- 2.1.6 2005/05/24
2790 Added support for SRW sort in Generic Frontend Server. Patch
2791 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2792 sortKeys - or NULL if none is provided.
2794 Fixed bug #307: It was impossible to specify indefinite/no timeout
2795 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2798 Added support for multiple languages and charsets to be specified in
2799 ZOOM. Each charset/language is separated by a blank. If negotiation is
2800 in effect in init-response, Option
2801 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2802 Code based on patch by Vasiliy Osadchuk.
2804 Fixed bug #306: infinite recursion that occurred when calling
2805 yaz_log_level_init as the first call (before other log level or
2808 Fixed bug in scan handling in front end server: if preferred-Position-In-
2809 Response was non-present, a NULL pointer referece was performed.
2811 --- 2.1.4 2005/04/26
2813 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2814 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2815 now defined for all those error codes. So instead of putting 109 in
2816 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2817 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2819 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2822 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2824 Program yaz-client now exits and produces an error message if multiple
2825 Z39.50 servers are specified on the command line (none or one allowed
2828 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2831 --- 2.1.2 2005/03/16
2833 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2835 Fixed bug #272: Preserve spacing for CCL terms.
2837 --- 2.1.0 2005/03/14
2839 Added support for virtual hosts and multiple backend servers for
2840 the YAZ frontend server. The configution is XML based and
2841 support specificition of CQL to RPN mappings and explain information.
2842 See section "Virtual Hosts" in the YAZ manual.
2844 Extended OPAC display utility. OPAC display utility renders
2845 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2846 to supplement yaz_marc_decode_wrbuf.
2848 Fixed a bug in MARC decoder that could caused it to crash for some
2849 invalid MARC records. More diagnostics and warnings where added in
2850 XML output (warnings, etc are stored in comments).
2852 --- 2.0.34 2005/02/08
2854 Fixes for UNIX domain sockets. Bug #261.
2856 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2858 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2859 Added yaz_marc_subfield_str which defines subfield lead string which is
2860 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2861 yaz_marc_endline_str which defines end of fields string used in
2862 YAZ_MARC_LINE format. Default string is newline.
2864 Experimental support for MarcXChange. This format can be produced
2865 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2866 http://www.bs.dk/standards/MarcXchange.xsd
2868 Added yaz-client commands scansize that sets maximum number of
2869 entries to be returned by scan.
2871 --- 2.0.32 2005/01/11
2873 Added support for SRW scan in yaz-client and Generic Frontend Server.
2875 * Added whereInList member to SRW Scan Term.
2877 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2879 Fixed NMEM system to return aligned blocks on the smallest boundaries
2880 that are suitably aligned for all possible types on the particular
2881 architecture YAZ is being built for.
2883 --- 2.0.30 2005/01/04
2885 Fixed numerious warnings that was issued with newer versions of GCC.
2887 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2888 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2891 Make YAZ Generic Frontend Server slightly faster.
2893 Enhance (and reduce) logging for Generic Frontend Server.
2895 Revert YAZ log system so that it flushes every write operation
2896 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2898 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2899 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2900 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2901 will effectively disable old definitions.
2903 --- 2.0.28 2004/11/09
2905 Added yaz_log_time_format which specifies log format using
2908 Added yaz_log_module_level which returns mask for a module. Value
2909 is non-zero mask a if module is enabled; zero if disabled.
2911 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2912 in include/yaz/cql.h.
2914 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2916 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2918 Fixed bug #172: RPM builds does not enable SSL.
2920 Doxyfile.in part of dist. Doxyfile generated by configure.
2922 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2923 are given and the corresponding component does not exist.
2925 Extend CCL documentation in YAZ reference. Describe r=r.
2927 --- 2.0.26 2004/10/01
2929 Fixed MARC->MARCXML conversion to properly deal with
2930 fields, subfields, indicators having non-ASCII characters.
2932 Fixed MARC->MARCXML conversion so that ASCII control characters
2933 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2936 Added YAZ GFS support for conversion from Z39.50 surrogate
2937 diagnostics to SRW surrogate diagnostics.
2939 Bug fix: YAZ GFS did not return schema in explainResponse.
2941 --- 2.0.25 2004/09/30
2943 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2944 now converts recordSchema to elementSetName as well as schema URI.
2946 Fixed bug in COMSTACK that prevented HTTP request packages from being
2949 --- 2.0.24 2004/09/29
2951 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2952 does not require white-space before and after the dash in a range, e.g.
2953 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2956 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2957 due to new GCC removing "redundant" code.
2959 Added yaz-client commands scanpos and scanstep that sets preferred
2960 position and step-size for scan.
2962 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2964 Added CCL utility ccl_qual_buf which parses one or more CCL
2965 spec lines in a buffer.
2967 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2968 of name and value - ignoring empty lines and comments.
2970 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2972 Added odr_get_element_path which returns current element path for an
2973 ODR handle. This utility is useful in error handling or user-defined
2976 Added ODR_PRINT utility odr_set_stream which is is a more generic
2977 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2978 to a write function and pointer to close function. The close function - if
2979 non-NULL - will be called during odr_destroy.
2981 Fixed bug in CCL parser where truncation char was not removed from
2982 right side when truncation=both was in effect.
2984 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2987 --- 2.0.23 2004/08/11
2989 Fix buffer overrun in CQL parser when dealing with proximity (%).
2991 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2992 to UTF-8/UCS conversion is now only based on codetables.xml.
2994 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2996 --- 2.0.22 2004/08/06
2998 Add support for more "commit changes" in ZOOM (uses Extended Services).
3000 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
3003 Yet another small fix for configure of SSL.
3005 --- 2.0.21 2004/05/14
3007 Fix SSL libs for configure when --with-openssl=DIR is given.
3009 --- 2.0.20 2004/05/10
3011 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
3013 SSL comstack now uses yaz.pem certificate file on server side
3014 by default. Certificate filename can be configured by calling
3015 comstack function cs_set_ssl_certificate_file before cs_bind is used.
3017 Fix bug regarding multiple calls to ZOOM_connection_connect.
3019 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
3021 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
3022 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
3024 ZOOM now allows inspection of X509 peer certificate for verification.
3025 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
3027 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
3028 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
3029 as "modular" but it simplifies things.
3031 Added cs_get_peer_certificate to that returns peer X509 PEM.
3033 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
3034 NULL if SSL is unavailable.
3036 Documentation about MARC decoding tools.
3038 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
3040 --- 2.0.19 2004/03/30
3042 Rename CHANGELOG to NEWS to follow GNU style packing.
3044 Fix bug with missing initialization of member in init_diagnostics.
3045 This bug affects threaded version of GFS server.
3047 --- 2.0.18 2004/03/20
3049 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
3052 Ensure zlib.dll is packed with Windows install.
3054 --- 2.0.17 2004/03/17
3056 Fix encoding of xsd:string to use text instead of CDATA.
3058 Fix endless loop in CQL parser with unbalanced ".
3060 Use a more compact way to store MARC-8 conversion tables.
3062 --- 2.0.16 2004/03/16 Debian only
3064 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
3067 Update CQL parser to use new CQL 1.1 modifiers for booleans and
3072 --- 2.0.15 2004/03/01
3074 Another fix for decoding of XML packed records.
3076 --- 2.0.14 2004/02/25
3078 Fixes for Chunked encoding. White space not ignored after length spec.
3080 Update NS and use default NS for SRW diagnostic elements.
3082 --- 2.0.13 2004/02/23
3084 Implement ZOOM_resultset_cache_reset which resets record cache.
3086 Implement ZOOM_resultset_sort which sorts a result set.
3088 Implement chunked HTTP transfer.
3090 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
3092 --- 2.0.12 2004/02/16
3094 Added member 'schema' to bend_explain_rr structure so that backend
3095 can specify explain record identifier. Defaults to Zeerex 2.0.
3097 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
3099 --- 2.0.11 2004/02/16
3101 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
3104 Added init command for yaz-client which sends "extra" init request.
3106 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
3107 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
3109 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
3111 Make ZOOM error code for "invalid query".
3113 Fixed compilation for SSL which wasn't properly enabled for all platforms.
3115 --- 2.0.10 2004/02/05
3117 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
3120 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
3122 Added option -p <file> to make Generic Frontend Server to write PID file.
3124 Added option -D to put Generic Frontend Server in background on its own.
3126 Make ZOOM C recognize option "password". If unset, "pass" is used
3127 (for backwards compatibility).
3129 Fixed a bug in Generic Frontend Server that could make it crash if a
3130 client sets characterSetNegotation bit, but didn't pass negotiation stuff
3133 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
3134 Must be issued before open, in order to be in effect.
3136 --- 2.0.9-6 2004/01/12 Debian/Windows
3138 Make the SRU server more picky WRT unknown params, etc.
3140 Bug fix: ZOOM scan response didn't return displayTerm - when present.
3142 New YAZ client command, options, that sets Z39.50 options.
3144 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3145 options from a string of tokens (one token for each option bit).
3147 Update SRW diagnostic code messages.
3149 --- 2.0.9-5 2004/01/07 Debian/Windows
3151 Handle user defined stylesheet for SRW/SRU.
3153 --- 2.0.9-4 2004/01/06 Debian/Windows
3155 Fix bug in decoding of Content-Length.
3157 --- 2.0.9-3 2004/01/06 Debian/Windows
3159 Fix a bug with decoding of XML packed records.
3161 --- 2.0.9-2 2004/01/05 Debian only
3163 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3165 Fix bug in SRW/SRU diagnostics decoding.
3167 --- 2.0.9 2004/01/05
3169 Fixed bug in Generic Frontend Server which could drop records exceeding
3170 preferred message size. Reported and fixed by Irina Dijour.
3172 Fixed calculation of package size for structured records in Generic
3173 Frontend Server. Reported and fixed by Irina Dijour.
3175 Fixed namespace for SRW/SRU diagnostics.
3177 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3179 --- 2.0.8 2003/12/22
3181 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3182 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3185 CQL changes to reflect recent changes to the specification:
3186 * Documentation talks about context sets instead of index sets.
3187 * Documentation talks about indexes instead of qualifiers.
3188 * The CQL-to-PQF transformer's configuration file now uses
3189 "index.set.name = <attributes>" instead of the old form
3190 "qualifier.set.name = <attributes>". (Both forms are still
3191 understood but the latter is deprecated.)
3192 * CQL terms with no explicit index specified are now interpreted as
3193 cql.serverChoice instead of srw.serverChoice (which of course
3194 behaves exactly the same.)
3196 --- 2.0.7 2003/12/16
3198 MARC conversion can now generate ISO2709 output in another
3199 character set. yaz-marcdump uses this facility if you invoke it
3202 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3203 functions from there can be used from C++.
3205 --- 2.0.6 2003/12/04
3207 Frontend server now transfers memory from decoded packages to stream
3210 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3211 references to show up.
3213 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3214 the ZOOM Abstract API. The older names for the same options are still
3215 also supported for the benefit of old applications.
3217 ZOOM-C supports "implementationId" and "implementationVersion" options
3218 to go along with "implementationName". These allow the user code to
3219 specify identification strings to be sent to servers.
3220 Add OID for the new ExtLite attribute set.
3222 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3223 as requested/supplid by Ere Maijala <ere@atp.fi>
3225 For generic frontend server, reverse the order of
3226 "toolkit-supplied / application-supplied" strings sent as implementationId,
3227 Name and Version. Also, remove the spaces around the slash. This brings
3228 the GFS in line with the behaviour of ZOOM-C on the client side.
3230 Add function ZOOM_scanset_display_term.
3232 yaz-client shows scan displayTerm if present.
3234 Utility yaz-iconv is now installed by default along with the man page
3237 Extend configure check for OpenSSL to use pkg-config where available (such
3240 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3241 server to specify uid/gid/mask for socket using the format
3242 unix:[user=uid,][group=gid,][umask=mask,]file=path
3243 If file= is omitted the existing format is assumed, e.g.
3245 in which case the mask is 0666 (rw for everybody).
3247 Major restructure of YAZ source. All source in libyaz is in src directory.
3248 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3249 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3251 Added man page for utility yaz-marcdump (used to be called marcdump).
3252 yaz-marcdump is installed by 'make install'.
3254 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3255 of incoming package failed.
3257 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3259 Change prototype of odr_perror: add const to message string.
3261 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3263 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3264 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3265 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3266 DNS lookup. There should not be any compatibility problems with this
3267 assuming that blocking=1 or 0 is used.
3269 Fix bad reference in UNIX comstack in function cs_addrstr.
3271 Fix for compilation on AIX.
3273 The generic front-end server (server/seshigh.c) now supports returning
3274 Init diagnostics to the client in User-information-field, in
3275 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3278 --- 2.0.4 2003/09/04
3280 Allow any CQL relation (not just all,any,exact,scr).
3282 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3283 that features the same UI.
3285 Implemented command update0 in YAZ client which is equivalent to
3286 update but uses old of Ext Update ASN.1.
3288 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3289 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3290 Previously no OID was used for this info.
3292 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3293 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3294 returns 'malformed search term' otherwise.
3296 SortResponse member resultCount now set to NULL in sort handler of
3299 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3302 Add three new utility functions for translating OIDs between various
3303 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3304 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3305 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3306 char *oid_to_dotstring(const int *oid, char *oidbuf);
3307 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3309 Reverted modifications for ES Update definition for z_IU0Update
3310 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3311 is back to YAZ 2.0.2.
3313 String value attributes for CCL parser.
3315 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3316 which their FirstSearch server returns in Init responses, sometimes
3317 carrying useful diagnostic information when Init fails. This has the
3318 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3319 "z39.50/oclcui.asn", where its definition is somewhat different from
3320 what OCLC document on their web-site, as required to interoperate with
3323 Support for anonymous authentication in yaz-client. Use the command
3326 * Fix the OID of the Index Data-local "admin" Extended Service from
3327 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3328 the 1000, which indicates a locally-defined OID, was a mistake.
3330 --- 2.0.3 2003/06/20
3332 Fix CCL directive @case handling so that it affects string match for
3333 both CCL keywords and qualifiers.
3335 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3336 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3337 Decoder has been updated with ASN.1 changes as listed in
3338 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3339 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3340 z_IUUpdate, remains unchanged.
3342 ZOOM_record_get may now return a record in a specific character set.
3343 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3344 "from" is the character set of record as returned by target. "to" is
3345 the character set to be returned. If omitted, "to" is UTF-8.
3347 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3349 New ODR utility, odr_getelement, which returns name of element for
3350 which encoding/decoding failed.
3352 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3353 in cases where a required element was omitted.
3355 Bug fix: some MARC8 sequences were not converted.
3357 New ZOOM option "step" which specifies number of records to be
3358 retrieved in one chunk. Used in conjunction with "start" and "count".
3360 SRW support for yaz-client. Use scheme http: to use it, e.g.
3363 yaz-client no longer does (un)intelligent character set conversions
3364 by default. Can be enabled with charset and marc_charset commands.
3366 xmalloc trace fix for 64-bit systems such as DEC alpha.
3368 Solaris 2.6 compile fix.
3370 New function, cql_strerror() translates SRW error codes, as returned
3371 by cql_transform_error(), into human-readable English strings. Used
3372 in yaz-client diagnostics when appropriate.
3374 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3375 converts it into a type-1 query which is sent to the server. This
3376 makes CQL available for use with all Z-servers, as opposed to the tiny
3377 minority that can handle CQL queries themselves.
3379 --- 2.0.2 2003/04/28
3381 New Debian package layout similar to the Redhat Package layout.
3383 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3384 and search result respectively.
3386 --- 2.0.1 2003/04/25
3388 Redhat package is now several packages: libyaz (runtime libraries),
3389 libyaz-devel (development and documentation, and yaz (utility programs).
3390 Package spec file by Morten Bogeskov.
3392 New member 'schema' in struct bend_fetch_rr which the name of requested
3393 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3394 handler MAY set this to reflect the schema of the returned record.
3396 New member 'display_term' in struct scan_entry. GFS now sets member entries
3397 and allocates scan entries to be filled by user scan handler. In previous
3398 version, entries member was allocated by the scan handler. That still works,
3399 but the GFS will ignore member display_term - assuming it was NOT set by
3400 the handler. The fact that the GFS now allocates the entries both allows
3401 for new members and makes a scan handler easier to write.
3403 Fix CQL lex buffer overflow.
3405 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3406 SRU default recordPacking is string.
3408 SRU protocol support for frontend server.
3410 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3412 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3414 Added scan for the ZOOM shell (zoomsh).
3418 * String Identifers for Schemas (Amendment 5).
3419 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3420 Old definition for schema
3421 Odr_oid *schema; /* OPT */
3426 Z_InternationalString *uri;
3427 #define Z_Schema_oid 1
3428 #define Z_Schema_uri 2
3431 * resultCount parameter to Sort Response (Amendment 1).
3432 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3434 Support for SRW 1.0 over HTTP. This is an optional feature and
3435 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3438 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3439 on the same port. SRW SearchRetrieveRequests are mapped
3440 to bend_init,bend_search,bend_fetch,bend_close.
3442 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3444 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3445 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3447 ZOOM connections are SRW based if schem http is used for hostname
3448 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3449 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3451 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3452 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3453 distance=n, order=true/false, relation=le, prox unit=word. If
3454 n is omitted, distance 1 is used.
3456 Fixed problem with C compiler include path in wrong order.
3458 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3459 on Solaris. Patch from Ko van der Sloot.
3461 New MARC decode API. All new functions operate on a yaz_marc_t
3462 handle. The most important new functions are: yaz_marc_create,
3463 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3464 decode and destroy respectively. Decoder can produce formats
3465 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3466 include/yaz/marcdisp.h.
3468 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3469 to UTF-8, UCS-32, wchar_t or Latin-1.
3471 * Prototypes for yaz_iconv_-functions moved to separate header
3472 include/yaz/yaz-iconv.h.
3474 Make a few private functions 'static' in unix.c. This prevents
3475 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3477 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3478 are set when Init Response is received.
3480 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3481 but returns diagnostic set as well.
3483 New function yaz_strerror which is a portable wrapper for
3484 strerror/strerror_r/GetLastMessage.
3486 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3487 is returned for MARC. If type is "oai", then OAI MARC is returned.
3489 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3492 --- 1.9.2 2002/11/26
3494 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3496 Fix bad race conditions on SIGTERM and terminate gracefully in
3499 Move retrieval (data1) module to Zebra since nobody seems to be
3502 Add GRS-1 render for ZOOM using same format as yaz-client.
3504 --- 1.9.1 2002/10/05
3506 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3508 Fix broken ESpec handling in data1 module.
3510 SGML reader parses comments and makes them part of the data1 tree.
3512 Added several type casts so that YAZ compiles as C++ code.
3514 ZOOM didn't handle PDU encoding failures properly.
3516 Added more Bib-1 diagnostics (approved extensions).
3518 GNU configure: better check for iconv.
3520 More portable use of accept, getpeername. Check for socklen_t. Use
3521 int/size_t if socklen_t is not defined.
3525 PQF parser rejects bad queries - including those with extra
3526 characters in them. PQF parser used to silently ignore that.
3527 Cleaner API for PQF added, which allows you to get detailed
3528 error information for bad queries (see yaz/pquery.h).
3530 Fixed bug in ZOOM_record_get for type "database".
3532 Implemented mini iconv library supporting conversions between
3533 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3535 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3537 --- 1.8.9 2002/08/20
3539 Fixed ZOOM C record cache so that preferredRecordSyntax and
3540 elementSetName is used to check for already fetched records.
3542 --- 1.8.8 2002/08/02
3544 Added three members in bend_initrequest structure to facilitate
3545 character set negotiation.
3547 Fixed a bug in frontend server that could cause indefinite
3548 loops under rare conditions.
3550 Revised character set utilities (charneg.h) so that encoding
3551 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3553 For PQF, directive @term <type> sets term type for Scan/Search.
3554 Here <type> is general, string, numeric, null. The term type
3555 is inherited - just like @attr.
3557 New call odr_set_charset that sets character set conversion for
3558 international-strings on a ODR stream. Prototype is:
3559 int odr_set_charset(ODR o, const char *to, const char *from);
3560 The InternationalString is still represented as C string in YAZ
3561 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3562 won't). On the protocol level, you can use any encoding.
3564 Support for UNIX sockets in ZOOM.
3566 Solaris recv sometimes returns errno == ENOENT. It is treated as
3567 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3569 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3570 both client and server. Code by Morten Bogeskov.
3572 --- 1.8.7 2002/05/22
3574 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3575 that they can be used directly from Visual Basic. You must recompile
3576 your windows APP if you're using ZOOM.
3578 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3579 Commands "lang" and "charset" sets language and character set respectively.
3580 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3581 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3583 Attributes from multiple CCL fields may be OR'ed rather than merged
3584 using directive "@field or". Fields are still merged by default -
3585 equivalent to "@field merge".
3587 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3590 Fixed bug in zget for parameter ExtendedServicesResponse.
3594 --- 1.8.6 2002/03/25
3596 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3598 Client displays USR.1:SearchResult-1 (hits per term).
3600 Additional Search Info for search in Generic Frontend Server.
3602 Fixed CCL parsing of "field=s".
3604 WIN32 installer - using the excellent NSIS software from nullsoft.
3606 Fixed CCL parsing of "field = - <number>".
3608 Added function yaz_marc_decode that decodes MARC for line mode
3609 display or XML (similar to that used by JZKit).
3611 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3612 Z39.50. But ISO/ILL was, however.
3614 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3615 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3617 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3618 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3620 --- 1.8.5 2002/02/03
3622 New YAZ client features: Command completion and new commands:
3623 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3624 Code provided by Jacob Poulsen.
3626 New call oid_trav, that visits all registered OIDs via callback.
3628 Function ZOOM_record_get now returns const char pointer rather than
3629 void pointer. It saves a lot of type casts.
3631 For YAZ client, command "auth" now allows you to set authentication
3632 in IdPass style. It is enabled when three tokens are given - order
3633 is user, group and password.
3635 Fix memory leaks in MARC record handling for ZOOM.
3637 New option for YAZ client, -k <kilobytes> that sets
3638 maximum record size. Similar to -k option for generic frontend
3639 server and yaz-ztest.
3641 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3643 Prefix query parser reports "fail" when bad attribute set is given.
3645 Fix in MARC decoder. Proximity logging. Fix for attribute set
3646 in scan handler for server. Patches by Shigeru Ishida.
3648 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3651 Configure option --with-openssl=<dir> now works when a directory is
3652 specified. Patch provided by Morten Bogeskov.
3654 New option for YAZ client, -u <auth>, that sets authentication.
3656 ZOOM fix: error information was sometimes "missing", since error
3657 was cleared/reset too when it shouldn't.
3659 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3661 --- 1.8.4 2002/01/04
3663 Scan for ZOOM API. New object ZOOM_scanset. New functions
3664 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3665 ZOOM_scanset_destroy.
3667 New ZOOM function, ZOOM_connection_last_event, that returns type
3668 of last event (such as "receive data", "send data", "apdu received",
3671 New ZOOM option, schema, that specifies schema for retrieval.
3673 New CCL feature. Qualifiers can be aliases for one or more
3674 other qualifiers (if more than one is given, OR is used).
3676 ZOOM uses named result sets if target supports it.
3678 Two new YAZ client commands: . (dot, which sources a script of YAZ
3679 client commands), and ! (to execute shell command.). Implemented
3682 Working on Debian packages.
3684 --- 1.8.3 2001/11/19
3686 YAZ client enables named result sets only if target supports it.
3688 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3690 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3691 with key="host" to get same result.
3693 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3694 Function Z3950_resultset_record(s) returns references to records
3695 "owned" by resultset. To become owner use Z3950_record_clone.
3697 Function z_ext_record handles Extended Services. Thanks to
3700 --- 1.8.2 2001/11/12
3702 CCL Parser fix: ignore token comma when dealing with and-lists.
3704 Documentation updates for COMSTACK.
3706 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3707 Changed prototype Z3950_records. For some functions, int parameters
3708 were changed to size_t.
3710 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3713 New MARC decode/display function, marc_display_exl, which properly rejects
3714 non-ISO2709 records. YAZ client uses it.
3716 --- 1.8.1 2001/10/29
3718 Fix bug: local attribute set wasn't set correctly in PQF strings.
3722 * Old Z39.50 codecs no longer supported.
3724 Added ZOOM C binding. See http://zoom.z3950.org/
3726 Renamed states for COMSTACKs to avoid confusion with events.
3728 Implemented cs_look and proper cs_rcvconnect.
3730 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3732 Configure detects POSIX threads on OpenBSD.
3734 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3735 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3737 When error is returned from present handler, non-surrogate diagnostic
3738 is returned in present response (and fetch handler is no longer called).
3740 * Minor adjustments to pquery parser (PQF). Token characters may be
3741 escaped by using backslash (C-style).
3743 PQF parser allows string attribute values to be specified. For @attr,
3744 non-numeric characters after the equal-sign are treated as strings
3745 (e.g. @attr 9=title).
3747 CCL trunction character may be defined (@truncation in file)
3749 * function zget_ExtendedServicesRequest sets waitAction to
3750 waitIfPossible (was wait).
3752 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3755 CCL operator names may be set in field definition files (CCL_bibset).
3756 See ccl/bib1 for an example.
3758 Fixes in ASN.1 compiler for C++ compatibility.
3760 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3761 and "op_or" to avoid conflict with C++.
3763 Fixed problem with GNU readline detection on Redhat 7.0.
3765 Added step-size for Scan backend handler.
3767 Fixed bug that made the frontend server crash when no attribute
3768 set was specified for scan.
3770 Front-end server automatically switches to original working directory
3771 when installed as an NT service. Previously -w had to be specified to
3774 Added extended attributes for retrieval module (data1), so that data1
3775 records carry d1_readXML/SGML attributes. d1_read also supports
3776 null-data rules ( <tag/>)
3778 On UNIX when POSIX threads are available, a separate library libyazthread
3779 is created. Programmers should link with that library and the yaz library
3780 when using threads. The reason for the split was that some applications
3781 on Linux, such as Apache, doesn't work well when using shared objects that
3784 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3785 (or any frontend server) in SSL mode by specifying ssl: followed by
3786 address. Only tested on UNIX.
3788 Added feature for CCL module. Virtual structure s=al or s=ol generates
3789 and-list and or-list respectively instead of phrase search.
3793 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3794 log_mask_str. This was done to avoid name conflicts with other libraries
3795 (such as other PHP extensions).
3797 Added raw OID member for preferred record syntax (request_format_raw)
3798 and returned record syntax (output_format_raw) for backend fetch method.
3800 Config file yaz-config now accepts options so that it returns specific
3801 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3803 Shared library support for UNIX using GNU libtool.
3805 * Modified backend interface. Request/Response struct's replaced by
3806 one read/write C struct. For example bend_fetchrequest and
3807 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3808 Every handler - even search has to be registered in bend_init
3809 handler. This means that the YAZ library no longer refers to
3810 external functions and it makes it possible to make the whole
3811 thing a single DLL/SO.
3813 Added Segment handler for backend server.
3815 Added Zmbol/Zebra administrative functions to YAZ client.
3817 Threaded frontend server on UNIX (when POSIX Threads are available).
3818 Starting the server with option -T enables multi-threading.
3822 Added configure option --enable-comp/disable-comp to control use
3823 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3824 located in sub directory asn.
3826 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3827 in ${exec_prefix}/bin along with the other programs yaz-client and
3830 GNU automake used to maintain makefiles.
3832 Added several OID's.
3834 Changed retrieval module so that we can load records with no abstract
3835 syntax defined. Tagpaths in these records are fully composed of string
3838 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3842 On UNIX, the generated makefile now supports a proper 'make install'.
3843 The prefix can be set via GNU configure to set the install location
3844 (default is /usr/local).
3846 * YAZ programs client and ztest were renamed to yaz-client and
3847 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3848 locations, such as /usr/bin,/usr/local/bin,etc.
3850 * YAZ Header files were moved from include to include/yaz. YAZ Header
3851 files are referred to as include <yaz/log.h> rather than <log.h>.
3852 The YAZ include path (-I ..) is therefore the same as before. Programmers
3853 should update their #include statements or use -Ipath/include/yaz
3854 instead. The main motivation for doing this change is that YAZ header files
3855 can be installed in "standard" locations /usr/include,/usr/local/include
3856 without introducing conflicts, since ALL YAZ header files are stored
3857 in subdirectory yaz (under /usr/include for example).
3859 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3860 rather than project/workspace files. We switched because project files
3861 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3864 Changed name of logging function, logf, to yaz_log, to prevent name
3865 clash with some math-log functions. The YAZ header log.h defines logf
3866 to yaz_log (#define) so there should be no incompatibilities by this
3869 Added bend_start/bend_stop handlers for server. These handler are
3870 called on start/stop of server. For windows they are called whenever
3871 a service is started/stopped.
3873 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3874 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3875 in util/yc.tcl. The auto-generated C code structures are, in a few
3876 cases, incompatible with the old decoders. There are differences in the
3877 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3878 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3879 The preprocessor variable ASN_COMPILED is defined when the compiled
3880 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3881 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3882 wish to use the old encoders/decoders you can specify --disable-yc
3885 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3886 version so that it supports both new - and old version of DB Update
3888 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3889 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3890 change. The name parameter can be set to 0 in which no name is specified
3891 for the construction. The macros odr_implicit and odr_explicit sets name
3892 parameter to zero for the construction involved. New macros
3893 odr_implicit_tag and odr_explicit_tag are similar to the others,
3894 except that a name parameter is added. For programmers' that don't use
3895 ODR they probably only need to change the call to z_APDU and z_External.
3897 Added access control facility by interfacing the TCP wrapper library.
3898 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3899 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3900 name of the daemon and enables the access control as specified in
3901 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3903 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3904 den Dool <H.M.vdnDool@kub.nl>.
3906 Added reference ID parameter to most functions in server API - refer
3907 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3909 Changed name of ccl library to libccl.a (was ccl.a).
3911 Fixed bug in decoder for Explain (Category TargetInfo).
3913 Added support for GNU readline in client. Thanks to Jacob Poulsen
3914 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3916 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3917 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3918 IMPLEMENTATION! This change was made to the development version before
3919 the ZIG decided to retract the amendment. If any users MUST be
3920 compatible with the original Update definition, PLEASE CONTACT US, and
3921 we will include a separate definition corresponding to the old Update
3922 ES. Note that because of the change to the ASN.1 of the
3923 TaskPackageRecordStructure we cannot define a single structure that
3924 will support both versions.
3926 * Added const modifier to buffer parameter for some ODR/BER encoding
3927 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3928 completeWAIS, odr_dumpBER.
3930 Fixed bug in client.c which caused a crash when a scanResponse didn't
3931 contain positionOfTerm.
3933 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3934 * will cause an error in a client if a non-YAZ target sends both a
3935 * list of Scan entries and non-surrogate diagnostics.
3937 Retrieval module enhancements. Tag sets may be typed in the reference
3938 to it. From the .abs-file the "tagset" directive takes a third optional
3939 integer type for the tag set referenced. From a .tag-file the "include"
3940 directive takes a third optional type as well. The old "type" directive
3941 in the tag set itself is still recognized but acts as the default type
3944 Backend interface change. Individual Scan terms returned from bend_scan
3945 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3946 in include/backend.h.
3948 Retrieval module enhancements. Multiple tag sets and attribute sets may
3949 be specified in abstract syntax specs. Revised the error/warning for
3950 logging messages reported by the retrieval module when reading the
3953 Object Identifier system (oid_..) changed. The API is backwards
3954 compatible but the oid-routines now allocates new OID's when needed.
3955 Raw OID's may be specified in oid_getvalbyname.
3957 YAZ now uses GNU configure to generate Makefile(s).
3959 * Minor changes in some of the member names of DeleteResultSetRequest and
3960 DeleteResultSetResponse. See include/proto.h.
3962 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3963 and added member 'languages' in TargetInfo (which was missing).
3965 Changed the way attribute sets are handled in the retrieval
3966 module. These are now cached, just like the abstract syntaxes
3969 Changed YAZ so that it links with compiled ASN.1.
3971 Added Explain-schema definitions and mapping routines. The following
3972 Explain categories have been implemented: AttributeDetails,
3973 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3975 Fixed minor bug in Windows version of Server Library.
3977 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3979 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3981 Added EXTERNAL: UNIverse Resource Report (non-standard).
3983 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3984 ENUMERATED and SET OF.
3986 * Added 'const' to some of the char pointer arguments for the
3987 functions, data1_read_node, data1_getelementbytagname,
3988 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3991 Fixed bug in data1_insert_taggeddata - the last_child member of
3992 parent wasn't initialised.
3994 * Changed data1_read_record and data1_read_node so that the supplied
3995 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3996 doesn't refer to any parts of the "SGML"-buffer.
3998 Fixed bug in server library (Windows version of statserv_remove).
4000 * Changed code so that it compiles as C++. The type definition
4001 of Odr_fun which is a member of Odr_arm was changed. The result is,
4002 that an explicit typecast is needed for the fun pointer when
4003 using Odr_arm - as in:
4004 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
4006 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
4008 Implemented the new structured date and time definition as approved
4009 by the ZIG. Added schemaId element to the specificTag in Espec-1
4010 (also approved at the last ZIG). Thanks to RVDM.
4012 Added some Object identifiers (RVDM).
4014 Changed the Update Extended Service (RVDM).
4016 Added command "refid" to client which specifies referenceId for
4017 the following requests.
4019 Implemented extended service handling for server. See ztest.c
4020 for an example as well as backend.h. New handlers are registerd
4021 in the Init handler.
4023 * Changed interface for sort in server.
4025 Added new members to statserv_options_block. It allows a server
4026 to read options from another source than just the command line. Thanks
4027 to Charles Woodfield.
4029 * Changed definition of Z_Triple in file prt-grs.h - member boolean
4030 renamed to zboolean. Some C++ compilers complained about the name.
4032 Minor changes to gils.abs. Added index 's' (sort) on title
4033 and date/time-last-modified.
4035 --- 1.4pl2 1998/1/30
4037 Fixed bug in server library regarding inetd mode (-i). This bug
4038 was introduced by release 1.4.
4040 --- 1.4pl1 1998/1/29
4042 Added sort facility in client and backend server interface.
4044 Fixed problem with dependencies in Makefile(s).
4046 Fixed bugs for encoders/decoders of extended services and
4049 Implemented sub-tree feature for schemas. Sub-trees are
4050 referenced in *.abs-files. See explain.abs for an example
4051 of the use of this feature.
4053 Modified bib1.att; local attributes for ANY didn't include
4054 ANY itself (only affects use of the retrieval module).
4056 Fixed bug in plain SGML reader in function data1_read_node:
4057 tags with prefix "var" was incorrectly interpreted as variants.
4059 Added feature "sub-schemas" to enable references to - and definitions
4060 of - group of elements.
4062 * Removed member parent from type data1_element (in data1.h).
4064 Implemented function odr_nullval() that returns the value of
4067 * Removed member num_children from data1_node (in data1.h).
4069 Made NT service interface part of the server library. The
4070 function statserv_main uses the NT service when required and
4071 calls the statserv_start / statserv_close routines.
4073 Routine zget_SearchRequest and zget_PresentRequest fills
4074 resultSetName/Id member with "default" instead of "Default".
4076 Fixed memory leak in server. Request queue member wasn't freed.
4078 Fixed nmem_exit so that memory is freed.
4082 Revised the CCL parser utility to be thread safe.
4084 Added function, oid_ent_to_oid, to replace the function
4085 oid_getoidbyent, which is not thread safe.
4087 * Added nmem_init and nmem_exit to initialize and release
4088 NMEM resources. Function nmem_init should be called once in the
4089 initial thread before NMEM/ODR is used. statserv.c and client.c
4090 have been changed accordingly. The change was necessary to make
4091 NMEM thread safe. The NMEM memory pool is shared amongst threads
4092 in a process. Unix-based applications will still work fine without
4095 Added NT Services interface for the the Z39.50 (statserv) Server.
4096 Refer to the ztest.c source on the usage.
4098 Windows 95/NT port using MSVC5.0. Project files are included in the
4101 * Defined new 'global' handle for the retrieval (data1) system. The
4102 new handled, data1_handle, describes the state of the data1 system.
4103 This handle is passed as first argument to virtually all
4104 data1 related routines. The functions data1_create and data1_destroy
4105 creates and destroys a data1 handle respectively.
4107 Added ODR encode stream member to all backend request structures
4108 init, search, scan etc. This stream should be used to allocate all
4109 memory used for the response when thread safe operation is needed.
4111 Changed the comstack utility, cs_addstr, to be thread safe. The
4112 returned hostname string returned by the function is now part the
4115 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
4116 function. The cs_straddr takes a COMSTACK handle as argument, so this
4117 function must be used after cs_create and before bind/connect.
4118 This function is thread safe.
4120 Moved test server to 'ztest' directory - generic server code still
4121 in 'server' directory.
4123 Made prefix query (pquery.c) utility thread safe.
4125 Added new function modifier YAZ_EXPORT to 'export' public DLL
4126 functions when using windows (see include/yconfig.h).
4128 Added definitions to the OID database (util/oid.c) (RVDM).
4130 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
4132 Added call to ccl_rpn_delete in client program.
4134 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
4135 release of RPN structure.
4137 Added support for C++, headers uses extern "C" for public definitions.
4138 With input from RVDM.
4140 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
4141 Thanks to Ronald van der Meer (RVDM).
4143 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4145 Added support for private extensions to the OID database
4146 (oid_setprivateoids()). Thanks to RVDM.
4148 Added optional, physical ANY (key replication)
4150 Fixed null-reference problem in GRS-1 output filter.
4152 Proximity operator added to Prefix Query Format (PQF).
4154 In test client command "base" accepts multiple databases.
4156 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4160 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4162 Smallish bug-fixes in the new encoders/decoders (explain).
4164 Bug fixed in DeleteRequest.
4166 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4168 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4170 Added SOIF syntax (using private OID for now) to retrieval module and client.
4172 Added Update extended service.
4174 Added SearchResult-1 additional info structure.
4176 Added optional CCL (ISO8777) interpreter as separate module. Available
4179 --- 1.2 1996/6/10 (1st anniversary release)
4181 Added Summary record syntax. Lightly tested.
4183 Added OPAC record syntax. Untested.
4185 Added ResourceReport service encoders/decoders. Untested.
4187 Fixed bug in z_Unit - wrong tagging on unitSystem.
4189 Fixed bug in the DiagRecs decoder.
4191 Added options for max PDU size and session timeout to frontend-server.
4193 Added documentation of query-language parsers and other supporting utilities.
4195 [frontend-server] Added Attribute set to the bend_scanrequest API.
4197 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4198 surrogate diagnostics were generated.
4200 [retrieval] Allow multiple local values for attribute.
4202 [retrieval] Allow multiple attributes per element in .abs files. index type.
4204 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4206 --- 1.1pl2 1996/4/10
4208 Minor changes, mostly specific to Zebra's requirements (retrieval)
4212 Repaired bug in frontend server when running multiple listening
4213 endpoints in dynamic mode.
4215 z_External() now won't break if a known, ASN.1 value comes encapsulated
4216 in an octet-string. The value will pass through unmodified in an Odr_oct.
4218 Added a bit of code to the demo client to decode & display
4219 ASN.1-structured records represented in the octet-aligned branch of
4220 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4222 Added z_ext_getentbyref() to the ASN module. Doc updated.
4224 * Completed the SCAN definition in the ASN module. This may break SCAN
4225 code based on older YAZ-versions at compile-time. The fix is easy -
4228 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4229 under the SCAN definition. Remember to initialize this, server-people.
4231 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4232 that this does not extend to ODR and ASN.
4234 Comstack allows insertion of established socket (primarily for
4235 inetd-operation of servers). Doc updated.
4237 Front-end server can now start from the inetd in TCP mode. Doc
4240 --- 1.0pl4 1996/1/24
4244 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4245 the rank and record number.
4247 Adjustments to the frontend server.
4249 Fixed diagnostic BER dumper. It ignored the file argument.
4253 Various changes to retrieval module.
4255 Changed the union discriminators of the protocol files from enums to
4256 ints paired with #defines.
4258 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4261 *Changed operator in the RPN structure to 'roperator', again to avoid a
4264 Fixed problems in Explain decoders/encoders.
4266 --- 1.0pl2 1995/12/6
4268 Memory bug in log module fixed.
4270 --- 1.0pl1 1995/12/5
4272 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4274 Bug in Explain DatabaseInfo module fixed.
4276 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4280 The shift to v1.0 signals that we now consider the *core* functionality
4281 of YAZ reasonably stable (the core being more or less equivalent to
4282 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4283 tested (Explain not at all - though that will happen soonish).
4285 Minor changes to code to support Windows port.
4287 Various minor changes after we're getting to use GRS-1 & co. more.
4289 Added Espec-1 format.
4291 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4292 of the protocol and it cannot be selected when encoding (maps into 'string'
4293 when decoding). Needed to talk to some servers.
4295 Demo client can request simple element set names.
4297 Added Diagnostic Format encoders/decoders.
4299 Added simple Close handling to frontend server (no hooks for resource
4300 reporting yet), and demonstration client.
4302 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4304 --- 1.0b3 1995/08/24
4306 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4307 handled incorrectly when records were requested in the searchResponse. This
4308 will only affect you if you use the frontend-server.
4310 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4311 Test-client will ask for and print GRS1. Ztest will return dummy records
4314 Added Explain encoders/decoders to the service-level API. Untested.
4316 Added Extended Services: Item Order encoders and decoders to the Service-
4317 level API. Untested. We could use a recent copy of the pertinent bits
4318 of the ILL protocol to add those bits.
4320 Added diagnostic format 1 encoders/decoders to the service-level API.
4323 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4324 odr_cons.c, which causes a more correct output.
4326 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4327 was always set to 0 when no records were requested in the searchRequest.
4329 * Added better external-handling. This shouldn't harm old code that
4330 *encodes* externals. It can break code that looks for a
4331 'single-ASN1-type' representation, since those types that are known
4332 are now decoded immediately. Look at the SUTRS sample code in
4333 seshigh.c and client.c. Documentation updated.
4335 Handling of structured records in bend_fetchresponse. Length -1 marks
4336 structured record, type is deduced from format field.
4338 --- 1.0b2 1995/06/27
4339 Fairly quick maintenance release to add SUTRS support.
4341 Fixed handling of SUTRS records in the demonstration client.
4343 * Added format field to the bend_fetchrequest and bend_fetchresponce
4344 structures of the backend API (frontend server). When the record is
4345 returned, the value of the format field is mapped to an OID. The
4346 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4347 of the record. The special value VAL_NONE in the bend_request means
4348 that no specific format was requested by the client. Documentation
4349 updated accordingly. Test server (ztest) will return a fixed dummy
4350 SUTRS record if your client requests SUTRS.
4352 Documentation updated accordingly.
4354 You can now set external libraries and RANLIB support in the top-level
4358 First public release.
