24 Stop building debs for Ubuntu raring, quantal, oneiric.
26 CCL YAZ-781: for multiple use attributes in a specification the
27 generated RPN will perform @or on each term.
28 For spec: term u=31 u=1016
29 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
31 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
33 CCL YAZ-779: combo qualifier should allow for forward references
35 Fix buildconf.sh, automake too old on centos5 YAZ-778
36 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
37 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
38 accepts it without a warning.
42 GFS: client_query_charset conversion YAZ-777
43 This is a feature for Z39.50 clients that sends queries that are not
44 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
45 encoding given to UTF-8.
47 Echoed SRU arguments support YAZ-776
48 This is achieved with new function yaz_srw_get_pdu_e.
50 ZOOM: expire times set for redis/memcached YAZ-772
51 For both redis and memcached option --expire=seconds sets expire
52 time for a result-set/search. Default time is 600 seconds (10 minutes).
56 No [rest of output is omitted] limit for yaz_log YAZ-774
58 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
60 For ICU testing, pass -o to yaz-icu. This will test the
61 icu_iter_get_org_info function.
63 Fix null ptr reference for freeReplyObject YAZ-773
67 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
69 RPM: do not build with libmemcached support. The libmemcached library
70 on CentOS 5/6 does not work reliably for us (redis to the rescue).
72 configure: only allow libmemcached version 0.40 or later. That's the version
73 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
74 that's not an option, consider redis.
78 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
80 Fix zoom+memcached: present request out of range YAZ-767
84 CCL: add new qualifier r=omiteq which will omit relation=equals
85 for ordered relations. This should be used in combination with either
88 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
90 Solr: simplify yaz_solr_decode_response
92 Solr: use different local var for string manipulation
94 Solr: Get rid of hardcoded limit of extra_args
96 Solr: encode lucene query type YAZ-736
97 Make sure the queries are treated as traditional "lucene", because that's

104 Build packages for Ubuntu Trusty Tahr 14.04 LTS
106 wrbuf_cstr: fix off by one error.
108 wrbuf_buf: make it always return non-NULL
109 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
113 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
115 zoomsh: offer option -a apdulog
116 As we're used to from yaz-client and GFS based servers.
118 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
119 existing setting apdulog takes effect.
121 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
126 Add re-entrant CQL/Solr/RPN query conversion functions.
127 The re-entrant functions are: cql_transform_r,
128 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
129 These have same functionality as cql_transform,
130 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
131 return the additional infomration as WRBUF to make them re-entrant.
133 Remove CQL to Solr conversion and base solr_transform_t on
134 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
135 data structure as cql_transform_t.
137 cql2pqf utility allows RPN to Solr conversion
139 Fix assert in ZOOM when http connect fails YAZ-757
141 --- 5.0.22 2014/04/09
143 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
145 wrbuf_cstr: make it thread safe YAZ-753
147 yaz_log_init_file may take fd=<no> to open log file at the FD given.
149 --- 5.0.21 2014/03/21
151 Offer new utility function zget_AttributeList_use_string.
153 New conversion step, solrmarc, for record conversion module.
155 --- 5.0.20 2014/03/13
157 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
158 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
161 --- 5.0.19 2014/03/10
163 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
164 The standalone ZOOM sort was completely broken since 5.0.13.
166 ZOOM: generate event Connect rather than None for partial connect
167 (in fact getaddrinfo resolving).
169 ZOOM: only supply clientIP for InitRequest. Rather than for all
172 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
174 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
175 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
176 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
178 New "Facets" section in the documentation.
180 --- 5.0.18 2014/02/27
182 Call exsltRegisterAll in yaz_init_globals, so that all applications
183 using YAZ will have EXSLT things enabled.
185 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
187 Update various URLs to the re-organized SRU pages at LoC.
189 --- 5.0.17 2014/02/26
191 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
192 introduced in 5.0.12.
194 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
195 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
196 Do not call yaz_init_globals from log_mask_str_x. Problem introduce

205 Fix gcrypt not properly initialized YAZ-740.
207 --- 5.0.14 2014/02/19
209 Describe memcached option for ZOOM.
211 ZOOM: throw present request out of range again YAZ-739
212 Was removed in YAZ 5.0.13.
214 --- 5.0.13 2014/02/18
216 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
217 with localtime_r when threads + fork is used (such as Metaproxy).
219 yaz-config: quote some RHS values (that might include blanks)
221 zoomsh: shows SearchResult-1
223 zoomsh: sortby command
225 zoomsh: use proper list of connections and result sets YAZ-725
227 Avoid yaz_log in sigterm handler for GFS YAZ-737
228 Logging is still performed, but outside sig handler.
230 New ZOOM C feature: result-set caching with memcached. Example:
231 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
233 Remove SSL via OpenSSL support YAZ-732
234 Also deprecate two functions from comstack that aren't working with
235 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
237 Revert "Bison: use %name-prefix directive rather than -p option"
239 --- 5.0.12 2014/01/22
241 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
243 SRU GET/Solr base URLs may hold additional ?args YAZ-729
244 ZOOM option extraArgs already does this, though. It seems useful
245 when dealing with Solr targets to limit by filter, eg.
246 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
248 Remove #fragment for HTTP request encoding YAZ-730
250 Doc: Update list of DLLs/LIBs
252 Doc: update href link to Unix utils and Git.
254 --- 5.0.11 2014/01/15
256 ZOOM: fix "lost connection" problem with servers that uses both squid
257 and another proxy behind it that returns Location headers with relative
260 zoomsh: do not use readline for stdin (no tty) YAZ-724
261 Just use fgets in that case. If the user hits Ctrl-D a new-line
264 zoomsh: empty command ignored YAZ-723
265 rather than performing exit of zoomsh.
267 yaz-url utility offers option -v to enable verbose mode.
269 yaz_url uses yaz_check_location and offers verbose mode.
271 Add new function yaz_check_location.
272 This function gets an absolute URI from Location (HTTP redirect).
274 cookie API: introduce yaz_cookies_reset
276 Update cql.y for newer bison YAZ-720
277 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
278 longer supported. Instead one must use %lex-param and %parse-param .
280 --- 5.0.10 2014/01/09
282 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
285 rpn2solr: support truncation left(2), left&right(3) YAZ-718
287 Mention SRU version 2.0 in yaz-client man page.
291 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
296 Make cs_parse_host public.A
298 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
299 introduced in YAZ 5.0.6.
303 Fix buffer corruption for yaz-ztest record fetch.
307 Allow yaz-ztest to return user-defined records (one record per file).
308 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
310 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
311 Use the stream write instead of odr_printf which has a 4K tmp buffer.
313 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
317 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
318 can read and write this format. For record format JSON, yaz-ztest returns
319 MARC-in-JSON records.
321 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
322 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
326 Improve error reporting for ICU chains YAZ-707
327 Report config element+rule when ICU status is "failure".
329 ZOOM: stop fetching if present response has no records YAZ-710
330 Some targets return less records than their hit count would suggest.
331 This prevents ZOOM from continuing to fetch records if any present
332 response has 0 records in the response.
334 Ensure that GFS calls exit if any listener fails YAZ-710
335 Before, if XML config was in use, it would start the default
340 yaz-ztest: -V shows version (like yaz-client -V)
342 New iconv encoding: danmarc YAZ-692
344 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
346 daemon: only wait for immediate child rather than all children. YAZ-704
348 yaz-client: fix setting of SRU record schema. If scheme was unset, it
349 could lead to invalid memory reference.
353 yaz-ztest returns schema for MARCXML test records. SRU require that
354 recordSchema for records.
356 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
357 instead of non-surrogate diagnostic. This is a per-record failure.
359 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
360 may refer to multiple listeners now. Attribute listenref is a comma separated
363 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
364 option is given for GFS, the dirname of filename (for -f) is used
365 as prefix for options such as cql2rpn, ccl2rpn, etc.
367 Content-Type charset fixes YAZ-701 . Do not inspect charset in
368 Content-Type header for SOAP when decoding SRU. The payload (XML)
369 itself tells what encoding it is. In response, never supply encoding
370 in Content-Type. The response payload (XML) tells what it is (with no
371 encoding in XML it's UTF-8).
373 HTTP decoding: allow blanks in URL paths YAZ-700
377 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
378 and facets. Ensure recordData and recordSchema are always present in
379 record element, because they are required.
381 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
384 Simplify in a lot of places using odr_strdupn.
386 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
390 Increase various buffers in GFS's statserv_options_block
391 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
392 This change makes many type-casts redundant, and, thus simplifies code.
394 Remove last bits of WAIS support.
396 Remove member 'size' from Odr_oct.
398 Slim down the public part of 'struct odr'. Most elements are not part
399 of struct Odr_private.
401 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
402 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
403 In particular facets are supported in both client - and server side.
404 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
405 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
406 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
407 both request/response). This is what a search handler in the GFS
408 will see (regardless of whether operating in SRU mode or Z39.50).
410 Changes to the srw.h (SRU/Solr) definitions include:
411 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
412 (char*), which replace union query and query_type (int). This is because
413 SRU 2.0 supports a queryType parameter. This also means that, to carry
414 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
415 x-pquery=PQFstring (extention parameter). The extension parameter
417 - New element, packing, that has information about SRU
418 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
420 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
422 New element, packing, in Z_SRW_explainRequest.
424 New elements in Z_SRW_scanRequest, queryType and scanClause.
425 These replace query_type and scanClase untion. This is similar to what
428 --- 4.2.69 2013/10/01
430 GFS: log when closing down - at least SIGTERM YAZ-684
431 Also change formatting WRT PID logging a bit.
433 Improve display of MARC records with multi-byte subfield IDs YAZ-695
434 In some rare cases subfield identifiers are multi-byte characters.
435 This will try to deterime length of those and split accordingly.
436 This affects display in line mode as MARCXML/MarcXchange. The encoding
437 of ISO2709 is the same.
439 Change inp argument to const for yaz_read_UTF8_char.
441 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
443 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
445 Better check of marc leader info YAZ-691
446 Problem is that some systems generate MARCXML/MarcXchange with
447 funny headers. These will not work if encoded as ISO2709.
448 Some tests produce new output, due to updated warning messages
450 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
452 yaz-client: display MAB records YAZ-689.
453 Thanks for Heiko Jansen for this patch.
455 New utility z_get_HTTP_Response_server which allows both HTTP server name
456 and HTTP server URL to be given in response.
458 Debian: do not depend on obs tcl8.3.
460 Debian: do not depend on obs libicu36-dev.
462 --- 4.2.68 2013/09/23
464 GFS: pass additionalSearchInfo to search memeber search_input if
465 given. Otherwise pass otherInfo. Request for facets and other search
466 related things will be passed there in future versions of YAZ.
468 New ZOOM setting, authenticationMode, which allows authentication
469 paramters to be encoded in the URL rather than via HTTP Basic auth.
472 rpn2solr: fix nested AND/OR handling. YAZ-685
474 Add comparison routines for some Z-types, such as NamePlusRecord,
475 RPNQuery, Query, RecordComposition and OtherInformation.
477 --- 4.2.67 2013/09/19
479 Don't decode MAB as MARC. Just like we don't attempt to decode
480 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
482 CCL: allow quoted terms for date ranges. YAZ-681
484 Introduce ccl_parser_qual_search. This function makes old function
485 ccl_qual_search, from YAZ 2, available again.
487 Add yaz_facet_list_to_wrbuf. YAZ-683
489 --- 4.2.66 2013/09/11
491 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
492 schema was given for search. YAZ-675
494 Add Solr date range searches. YAZ-621
496 --- 4.2.65 2013/08/22
498 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
500 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
502 ISO2709/MARC parse most octet aligned records; not just those that
503 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
504 MARC parse more records instead of just dumping as is. YAZ-670
506 ZOOM: proper caching for variations of record schema. YAZ-671
508 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
510 --- 4.2.63 2013/07/17
514 --- 4.2.62 2013/07/11
516 New utility z_get_HTTP_Response_details - an extended version of
519 New utility yaz_url_get_error which returns error message of last
520 failed yaz_url_exec call.
522 yaz-url and url functions: allow max HTTP redirects to be controlled.
524 New functions yaz_file_glob2, yaz_xml_include_glob.
525 These functions takes a flags parameter, which, for now only controls
526 whether to fail inclusion of a non-existing file (without glob
527 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
529 --- 4.2.61 2013/06/20
531 For MARC XML parsing, allow record without leader. A fake/default leader
532 is inserted and a warning is tagged with the record.
534 ICU: fix leak in in icu_iter_get_org_info.
536 --- 4.2.60 2013/06/14
538 ICU: fix bug in icu_iter_get_org_info (un-init variable).
540 --- 4.2.59 2013/06/11
542 Implement z_HTTP_header_remove.
544 --- 4.2.58 2013/06/11
546 ICU: Disallow 0 ptrs for some ICU string utilities.
548 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
549 returns original tokens (before normalization).
551 CCL: avoid z39.58/regex truncation when not needed. Apply only the
552 conversion of those masks, when absolutely necessary.
554 CCL: configurable masking character - @mask. Default masking character
557 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
558 full response anyway, so a Transfer-Encoding header will obstruct the
561 --- 4.2.57 2013/05/15
563 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
564 picking a socket. Problem is that some systems has IPV6 support, but
565 we can't create sockets for them, so we pick AF_UNSPEC first.
567 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
568 use content_len to determine resulting Content-Length in HTTP response
569 and NOT Content-Length supplied in headers by user.
571 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
572 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
574 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
577 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
578 with big endian and unsigned char (by default).
580 --- 4.2.56 2013/04/26
582 Fix yaz-client connect (crash in 4.2.55).
584 --- 4.2.55 2013/04/26
586 Fix proxy/host problem for ZOOM that could occur if unix sockets
589 New Debian package libyaz4-dbg.
591 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
592 differently in tcpip_close.
594 --- 4.2.54 2013/04/17
596 Windows installer of YAZ includes YAZ4J as a component.
598 CQL: allow "extra terms" again, by default. Thus, the CQL parser
599 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
600 and earlier. CQL parser may operate in strict mode where queries
601 not conforming to the standard BNF are rejected (syntax error).
602 Whether the CQL parser operates in strict mode is controlled with
603 cql_parser_strict . Strict mode enabled with option -S for utilities
604 cql2pqf and cql2xcql .
606 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
608 --- 4.2.53 2013/04/10
610 New charset, MARC-8c, which is like MARC-8 but allows control characters
611 0x01 through 0x1F, except ESC to be passed through verbatim.
613 Fix a problem with duplicate sub field character in MARC output. Problem
614 happened only when output was MARC-8 encoded.
616 --- 4.2.52 2013/04/03
618 yaz-ztest: Use hash for fake hit count. Before, random number was used.
619 This is problematic for unit tests using yaz-ztest. This patch also makes
620 a hash for CQL queries. For RPN, any term with a leading digit will be
621 treated as pseudu hit count (to force any particular hit count by a client).
623 yaz-ztest: return unique MARC dummy records. Beyond record offset
624 24, the author surname is patched with offset to make all records
627 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
628 on system wide default (/proc/sys/net/ipv6/bindv6only).
629 @4 binds to IPV4 only. @6 binds to IPV6 only.
631 Update CQL API documentation a bit
633 CQL: don't accept extra terms for queries. Makes the CQL parser
634 stricly conformant to the standard.
636 --- 4.2.51 2013/02/12
638 GFS: scan handler gets extra_args from request and may return extra
639 response data . That's for SRU only.
641 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
643 --- 4.2.50 2013/01/30
645 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
647 OPACXML: sync spelling of availabilityDate in XML to that of Schema
648 opaxxml.xsd. The schema had the correct spelling of this member always.
649 The ASN.1 was mis-spelled and still is (API change) - we are
650 not changing this. However, the OPAC to XML conversion had yet
653 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
656 New function, z_ext_record_oid_nmem, which is similar to
657 z_ext_record_oid but takes NMEM rather than ODR
659 --- 4.2.49 2013/01/18
661 ICU: New conversion element 'join' which joins tokens into one
662 with a custom character given by rule attribute.
664 --- 4.2.48 2013/01/10
666 New GFS search member: present_number. This is a hint to the
667 search handler how many records are going to be fetched immediately
668 following search. There's no guarantee that it's going to be the case,
669 since it depends on hit count (for Z39.50 piggyback) and whether errors
672 Make a few functions static (private). The functions getbyte_stream,
673 ungetbyte_stream and yaz_gets are now private. They were never declared
676 yaz-marcdump: exit(5) for serious decoding errors
678 ISO2709 decoding: be more picky WRT header
680 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
681 was only used as to indicate that next-result-set-position should be
683 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
684 Based on patch from Ashley Sanders.
686 Make some functions static/private in PQF parsing. Those functions were
687 never declared in a public header and so should not be in use by
688 applications based on YAZ.
690 --- 4.2.47 2012/11/23
692 ZOOM: special options to control APDU logging.
693 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
694 logging of APDUs until "saveAPDU" option is set again. If logging is
695 already enabled the effect is that current APDU buffer is cleared.
696 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
697 logging (default behavior on new connection).
698 The APDUs sent/received can be obtained by using
699 Using ZOOM_connection_option_get(c, "APDU") or
700 ZOOM_connection_option_getl(c, "APDU", &l).
702 GFS: relay implementation_version from backend
703 From 3.0.40 and later, implementation_version from backend was
704 not used in init response at all.
706 --- 4.2.46 2012/11/15
708 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
709 mode at all. Probably never did.
711 Make a new version of ztest.pem that, at least, is not expired.
713 --- 4.2.45 2012/11/13
715 Fix description of CCL directive 'case'.
717 More tight checking of form arguments (yaz_uri_to_array). Makes
718 YAZ better at rejecting big and/or bad POSTs.
720 SRU decoding does not report more than up to 10 invalid arguments.
722 rpn2cql: less quotes in generated terms. Semantics unchanged, but
723 it's prettier this way.
725 --- 4.2.44 2012/10/25
727 New utility yaz_decode_init_diag. Defined in proto.h.
729 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
730 given for unix local socket.
731 The COMSTACK string for doing so is:
734 unix:/myfile:tcp:localhost:9999/mybase
735 unix:/myfile:localhost:9999/mybase
736 unix:/myfile:http://fakehost/mybase
738 debian: Use dpkg-buildflags in build process.
740 --- 4.2.43 2012/10/19
742 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
743 global's SRU service uses a recordPosition scheme starting from zero.
744 First record's position should be one
745 according to the standard.
747 --- 4.2.42 2012/10/18
749 Allow more namespaces for SRU. This is to allow, for example, an
750 incorrect namespace returned from server
751 http://services.igi-global.com/sru .
753 Minor fixes for compilation on Windows.
755 --- 4.2.41 2012/10/11
757 daemon: log total number of bad signals from child on stop so that it
758 is more easy to spot problems with child worker processes.
760 retrieval: empty backend name attribute omits element set
761 from being used in retrieval.
763 --- 4.2.40 2012/10/04
765 Implement Solr sort strategy "solr", similar to sru11 sorting.
766 This will implement the correct parameters on Solr requst to do
769 --- 4.2.39 2012/09/28
771 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
774 MARC: Extra/missing indicator handled for MARCXML.
775 The indicator length is given in header and is the same for the
776 whole record. If attributes ind1, ind2 are missing, then content
777 character defaults to blank. Extra indicator attributes (beyond)
778 indicator length are treated as an error.
780 Reformat: delete trailing whitespace
782 --- 4.2.38 2012/09/17
784 MARC: fix non-ASCII characters for leader. This is to ensure we can
785 generate XML in UTF-8.
787 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
788 in one node with structure word.
790 --- 4.2.37 2012/09/04
792 yaz-json-parse: JSON output may be pretty printed by using option
795 Increase default value of max message for Z39.50 Init for GFS, ZOOM
796 and yaz-client. Old value was 1 MB. New value is 64 MB.
798 --- 4.2.36 2012/08/22
800 yaz-client: don't display bogus records from SRU servers. Some SRU servers
801 return more records than given by *maximumRecords*. Skipping those in
804 record_render: simplify buffer return handling and fix at least one bad
805 memory reference, that broke the test_embed_record sometimes.
807 Allow http://user:pass@host notation for yaz_url_exec.
809 zoomsh: allow shell command to be executed. Via the system(3) call.
811 yaz_poll: Allow num_fds == 0
813 yaz-client: fix bad encoding of "itemorder item". The itemorder
814 item <no> - command forgot to use length of encoded Item Request
815 package. Error present since YAZ 3.
817 yaz-ztest: fix bad usage of session handle. Bug was introduced when
818 result sets were saved (271a9c83).
820 SRU recordPacking: guess record packing in response rather than looking
821 at the recordPacking element which, OF COURSE, changed semantics in SRU
824 Decode SRU 2.0 responses. The official namespace for responses, according
825 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
826 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
827 nature.com's server, however, usee namespace
828 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
829 we are now using a glob-expr to match up the namespace. ZOOM C and
830 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
831 I can not find a single real example showing the "real" namespace in
832 the documentation from OASIS. The namespace for requests is different
833 from responses, but this is not added to YAZ yet, when we don't encode
836 --- 4.2.35 2012/06/26
838 zoom/record_render: add support for Base64 decoding fo MARC records
839 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
840 which will decode base64 + ISO2709 marc-8 encoded material from text node
843 --- 4.2.34 2012/06/07
845 Add missing definitions ZOOM_resultset_get_facet_field_by_index
846 and ZOOM_resultset_facets_names.
848 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
851 Change APDU dump printing to avoid long leading blanks. For levels 16
852 or larger the level is shown and the indentation is truncated but
853 recursed with modula 8. This makes it still reasonable easy to read
854 - even for nested BER dumps.
856 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
857 return 0 (incomplete package) in case where the BER package was
858 considered too nested (return value of -2).
860 dumpber: lines of level 15 are not indented further. Two spaces per
861 indentation; indentation 15 or more is indented to a fixed indentation
862 and augmented with a level=<no> indication.
864 zoomsh: increase max size of command+args
866 GFS: No limit in RPN buf size in CQL to RPN conversion.
868 --- 4.2.33 2012/05/09
870 New function for daemon utility, yaz_daemon_stop .
872 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
874 --- 4.2.32 2012/04/25
876 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
877 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
879 --- 4.2.31 2012/04/23
881 YAZ daemon utility relays SIGUSR1 to child process.
883 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
884 would result in en empty database list - which in turn would result in
885 encoding failure for search.
887 Fix reading beyond string in yaz_sort_spec.
889 --- 4.2.30 2012/04/11
891 Add two new SRU diagnostics:
892 236: Access to specified database denied
893 1015: Init/AC: Maximum number of simultaneous sessions for Userid
895 Document the very useful ZOOM-C option "apdulog".
897 CQL to RPN: term may be passed through verbatim. This is enabled with
898 truncation.cql . The assumption being that the term is already CQL.
900 --- 4.2.29 2012/03/20
902 record_conv: leader spec may be given for marc element.
903 The leader spec is given as attribute leaderspec for element marc.
904 For example to convert a MARC21 record from MARC-8 to UTF-8:
905 <marc inputformat="marc" outputformat="marc"
906 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
908 record_conv: allow user-XSLT params. For example:
909 <xslt stylesheet="MARC21slim2DC.xsl">
910 <param name="myparameter" value="myvalue"/>
911 <param name="otherparameter" value="othervalue"/>
914 record_conv: fix error handling for missing marc charsets.
916 CQL: fix extra terms in wrong order.
918 --- 4.2.28 2012/03/06
920 record_conv: modify new API for conversion types. The conversion types
921 may be passed in new functions yaz_record_conv_configure_t and
922 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
924 Avoid mixed statement/variable declare; fixes compilation with Visual
927 --- 4.2.27 2012/02/28
929 Add non-standard SRU diagnostic: 235: "Database does not exist".
930 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
931 Update SRU to Bib-1 diagnostic maps accordingly.
933 CCL: add two new diagnostics for unsupported masking. The new
934 diagnostics are: "Embedded truncation not supported" and
935 "Single charcacter mask not supported".
937 --- 4.2.26 2012/02/23
939 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
941 --- 4.2.25 2012/01/11
943 Build YAZ for Ubuntu Oneiric.
945 CCL: allow parantheses for proximity operands. For example CCL query
946 (a) % (b) is now allowed.
948 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
949 marked dead, rather then being destroyed. If not, the session memory is
950 being free'd before the search/scan handler is finished. Also destroy
951 'request' memory in request_release rather than in various places,
952 which resulted in leaks from time to time.
954 --- 4.2.24 2011/12/21
956 cql_sortby_to_sortkeys: honor sort prefix.
958 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
959 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
960 The rpn2cql family of functions now always returns quoted CQL terms.
962 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
964 --- 4.2.23 2011/12/15
966 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
967 sequence is treated as one. For example, &&a=b&&&c& is identical to
970 --- 4.2.22 2011/12/05
972 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
973 APDUs for a connection to a WRBUF.
975 --- 4.2.21 2011/11/23
977 Fix cql_sortby_to_sortkeys. Completely broken before.
979 Make CCL's @truncation work again.
981 --- 4.2.20 2011/11/09
983 New ZOOM connection setting: tproxy. It's like proxy, but does not
984 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
985 to set resolved address + port for a connection outside ZOOM itself.
987 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
989 --- 4.2.19 2011/11/07
991 Fix uninitialized variable in Solr spell support (could cause SEGV
992 for SRU response decoding).
994 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
995 back-end's addinfo through into the ZOOM response addinfo.
997 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
998 they are separated by a colon and a space rather than simply
1001 --- 4.2.18 2011/10/28
1003 Add support for Solr spell-checking/suggestions through ZOOM.
1004 If a Solr target has been configured correctly for spelling-checking
1005 and suggestions, these will now be returned on the ResultSet option
1006 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1008 --- 4.2.17 2011/09/28
1010 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1011 with a flag whether to substitute escape sequences or not.
1013 --- 4.2.16 2011/09/22
1015 Fix nmem_strsplit_escape to substitute escape char properly.
1017 New option for zoomsh -e , which makes it abort on first error and
1018 return process exit code to indicate success/failure.
1020 YAZ options utility supports special option -- which makes all it treat
1021 all following arguments as non-options.
1023 --- 4.2.15 2011/09/16
1025 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1026 searched if absolute filename is given.
1028 Fix conv_xslt() error-reporting when stylesheet is not found.
1029 (The value of fullpath is meaningless in this situation.)
1031 --- 4.2.14 2011/09/07
1033 Fix problem in CQL sort node creation: un-initialized memory.
1035 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1036 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1037 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1040 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1041 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1043 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1044 will make it possible to use both single-character mask (#) and wildcard (?)
1045 in CCL . Throw diagnostic for left truncation because that is not supported
1048 --- 4.2.13 2011/09/01
1050 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1051 cases using escapes (\-sequences) and masking.
1053 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1054 would result in a read one byte beyond string.
1056 rpn2ccl may use Z39.50 masking for terms (t=z).
1058 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1060 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1061 not --cppflags (which seeems like an error in icu-config).
1063 --- 4.2.12 2011/08/27 RPM package only
1065 cql2ccl: fix conversion of terms: operator characters were not
1068 --- 4.2.11 2011/08/25 RPM package only
1070 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1071 CCL parser will map both # and ? to their regular expression
1072 quivalents (. and .*).
1074 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1075 of reserved CQL characters.
1077 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1078 is, so that they are passed through.
1080 --- 4.2.10 2011/08/24
1082 ZOOM SRU mode: more aggressive re-connect.
1084 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1085 made available as a utility function, declared in <yaz/logrpn.h>
1087 rpn2cql_structure() supports proximity nodes (except that the Type-1
1088 proximity node's "exclusion" binary is ignored, as there is no way to
1089 express that in CQL). Fixes bug #4564.
1091 --- 4.2.9 2011/08/18
1093 Fix SEGV that could occur if set command of zoomsh was given without
1094 value (2nd argument).
1096 Fix SEGV that could occur if unsupported transport was given for
1097 COMSTACK - say https (when SSL was unavailable).
1099 Build yaz-url on Windows too.
1101 --- 4.2.8 2011/08/11
1103 New utility to get web content. Header is url.h. A command line tool
1104 yaz-url is part of the distribution and packages.
1106 Fixes for SSL COMSTACK (when gnutls is in use).
1108 New functions yaz_base64{encode,decode}. Header is base64.h.
1110 --- 4.2.7 2011/08/03
1112 ZOOM C includes HTTP response buffer as additional info if it fails
1113 to decode the SRU response.
1115 Make wrbuf_json_puts available.
1117 --- 4.2.6 2011/07/28
1119 zoom: throw diagnostic for invalid value for option "sru". Before a
1120 bad SRU request was sent.
1122 Adding new utility wrbuf_vp_puts.
1124 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1126 --- 4.2.5 2011/07/21
1128 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1129 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1130 redirect was used at the same time.
1132 MARC line mode decoding: be less picky about length given - first
1133 5 digits of header that is.
1135 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1137 Changes to decoding of SRU records: a record with recordPacking=xml is
1138 modified with a new root element <yaz_record> if the recordData contains
1139 multiple children elements. This is to make the record XML parseable
1142 RPN to Solr conversion: encode special characters.
1144 Generic Frontend Server: fix uinitialized member, stepSize.
1146 --- 4.2.4 2011/06/21
1148 Fix a bug in SRU decoding of records.. The database records stored
1149 had un-initialized memory, but it would only be seen with yaz_record_render
1150 and type_spec="ext" .
1152 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1154 --- 4.2.3 2011/06/17
1156 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1158 --- 4.2.2 2011/06/10
1160 Add new utilities to convert from CQL to CCL . These utilities have
1161 prefix cql_to_ccl defined in cql.h.
1163 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1164 lead to memory heap corruptions when ICU utilities were in use.
1166 --- 4.2.1 2011/06/07
1168 Make compilation work without Libxml2.
1170 yaz-client: remove redundant blanks in display of searchResult-1 term
1173 --- 4.2.0 2011/05/18
1175 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1176 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1178 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1179 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1180 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1181 Note that the CQL sortby spec is only converted when the GFS is already
1182 converting from CQL to RPN (cql2rpn element).
1184 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1185 specify whether to collapse delimitors or not. The existing nmem_strsplit
1186 do collapse (collapse parameter = 1).
1188 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1190 Rename internal func yaz_use_attribute_create. While non-static, this
1191 function is not declared in a public header.
1193 --- 4.1.7 2011/03/15
1195 Add -lCrun when linking with ICU on Solaris.
1197 More quicks character set conversions for OPAC records.
1199 --- 4.1.6 2011/03/10
1201 fix problem with record_render: records were converted (character set
1202 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1204 --- 4.1.5 2011/03/08
1206 SRU: add methods for handling DADS SRU-proxy facets.
1208 Separate OPAC record character set for ZOOM_record. yaz_record_render
1209 allows a character set given as charset=from/opacfrom,to where 'from' is
1210 the character set of a bibliographic record, 'opacfrom' is character set
1211 of OPAC record and 'to' is the target character set.
1213 --- 4.1.4 2011/02/21
1215 yaz-client: show may XML format records. Command show followed by 'format'
1216 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1219 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1222 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1224 --- 4.1.3 2011/01/27
1225 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1227 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1228 this package can be distinguished from other vendors.
1230 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1231 as determined by configure
1233 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1235 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1236 returns no error and no record, the present request is considered
1237 partial (only a subset of the records could be returned by backend), and
1238 so it is appropriate to set Present Status to partial-4.
1240 --- 4.1.2 2010/11/02
1242 Move yaz-config man pages to section 1.
1244 More documentation about Solr.
1246 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1247 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1248 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1249 peers on some Linux systems. However, in general that does not work
1250 so YAZ can not rely on that to work. Debian changed behavior in this
1251 respect from Debian lenny to Debian squeeze (still testing as of Oct
1253 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1255 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1257 --- 4.1.1 2010/10/05
1259 Fix yaz-config output: echo_source not set correctly by configure.
1261 --- 4.1.0 2010/10/05
1263 Solr Web Service support for yaz-client and ZOOM.
1265 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1267 --- 4.0.12 2010/08/17
1269 Z39.50 facet support. Facet specifications are passed for search in
1270 other-information with ASN.1 as defined in facet.asn and OID
1271 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1272 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1273 3 is limit (number of entries to get in response). yaz-ztest returns
1274 dummy facets if a client asks for them.
1276 --- 4.0.11 2010/07/09
1278 CCL fixes: bug 2895 and bug 3539.
1280 GR1-display: add comma in display - was removed by mistake in
1283 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1285 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1287 --- 4.0.10 2010/06/18
1289 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1290 result set from a connection. The result set will be on its own
1291 thereafter; no operations on it will perform retrievals from a target.
1292 Only cached copies are returned.
1294 ZOOM C:fix case for HTTP servers responding with Connection:close.
1295 Ensure that if there is a current task it is resumed (like fetching
1296 more records in a result set) . Bug #3484.
1298 PQF parser: use odr_atoi for Odr_int (not atoi)
1300 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1301 values that contain any non-digits are treated as string attributes
1302 (previously decoding only checked for leading character ([0-9]). PQF
1303 encoding: attribute string values are not surrounded by double-quotes.
1305 --- 4.0.9 2010/05/21
1307 New utility for managing threads - thread_create.h.
1309 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1310 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1311 but YAZ' implementation do.
1313 Fixes for yaz_cond-functions on Windows 7.
1315 DLL export more symbols.
1317 zoomsh: show record do NOT render opac.
1319 Remove *.la files from Debian and RPM packages.
1321 --- 4.0.8 2010/05/11
1323 Debian package libyaz-dev depends on libgnutls-dev again (was
1324 removed in YAZ 4.0.6, but due to Libtool it is still needed
1325 even though yaz-config do not list libgnutls libs).
1327 ZOOM: Use only one WRBUF for returning string results for
1328 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1330 ZOOM: ZOOM_connection do not use a shared pointer to
1331 ZOOM_resultset after ZOOM_resultset is destructed by
1332 user. Reverts to YAZ 4.0.4 behavior.
1334 --- 4.0.7 2010/05/04
1336 record-conv: fix problem with at least one XSL conversion -
1337 due to probably incorrect usage of XML XSL documents.
1339 --- 4.0.6 2010/04/29
1341 Fix yaz-config for static mode and the use of SSL (gnutls).
1343 --- 4.0.5 2010/04/29
1345 Forward decl timeval struct in mutex.h and gettimeofday.h.
1347 yaz-config: fix 'static' mode linking.
1349 --- 4.0.4 2010/04/28
1351 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1352 are wrappers for pthreads or Windows. For Windows these are put in
1353 a separate DLL: yaz_cond4.
1355 libyaz.la (whole source) is compiled with thread. If thread support
1356 is enabled enabled, all source of YAZ is compiled with treading support.
1357 This allows core utilities such as yaz_log to use thread facilities.
1358 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1359 thread utilities. This commit moves mutex utilities (mutex.c) from
1360 libyaz_server.la to libyaz.la.
1362 yaz-json-parse displays leading text until error.
1364 --- 4.0.3 2010/04/09
1366 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1367 patch from Giannis Kosmas.
1369 SRU: no longer URL encode SRU database. The URL for an SRU server is
1370 a URL and such is alreeady encoded - at least when given with leading
1371 http:// or https://. This reverts behavior to YAZ 3.0.50.
1373 Support for new MARC XML notation TurboMARC which like MARCXML is a
1374 complete representation of MARC/ISO2709.. This one, however, is more
1375 compact and allows for faster processing with XSLT. TurboMARC can be
1376 used in the marcdisp.h API, from the yaz-marcdump utility and from
1379 yaz-ztest can be configured - via the database - to perform certain
1380 delays when it performs operations search, present and single record
1381 fetch. This allows testers to make yaz-ztest act as a real or even slow
1382 Z39.50 server. Refer to the yaz-ztest man pages for details.
1384 --- 4.0.2 2010/03/09
1386 wrbuf_destroy allows NULL WRBUF passed to it.
1388 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1390 Add ZOOM_connection_close.
1392 No fixed size buffers for ZOOM shell - bug #3257.
1394 tstodr: make it work on s390 platform.
1396 New icu iterator-functions. The new icu_iter-functions makes it possible
1397 to use ICU chains from many threads.
1399 yaz-client: better syntax check for show command.
1401 --- 4.0.1 2010/01/26
1403 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1406 New simple local-file XML include facility which allows file glob-patterns.
1407 Refer to yaz/xml_include.h.
1409 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1412 ZOOM_record_get supports new parameter "format" which makes it format XML
1415 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1416 JSONText in ECMA-262) is JSONValue, not JSONObject.
1418 --- 4.0.0 2010/01/20
1420 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1421 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1423 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1424 POSIX/Unix builds .so with major version 4.
1426 Remove old LOG_-defines from log.h. They have been obsolete and
1427 undefined by default for the last 5 years.
1429 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1431 GFS: Remove socket (int *fd) from search_rr handler. The socket
1432 descriptor ptr is a facility that allowed a search handler to supply
1433 a socket which would serve as a callback - when search was complete.
1434 This facility has now been in use for years.
1436 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1437 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1438 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1439 returns 'const char *' rather than 'char *. The returned string is
1440 read-only and should not be modified by applications. COMSTACK cs_close is
1441 now a void function - it no longer returns int. No applications check for
1442 the value and the implementations has always returned 0.
1444 ZOOM: use size_t for scan hit counts and str size. Functions
1445 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1446 occ (hit count) and len (string length) are now of type size_t pointer
1447 rather than int pointer. This is to be able to represent large hit counts
1448 and to also just to use the proper type for string length (strlen result).
1450 New JSON parser. Refer to include/yaz/json.h .
1452 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1453 Used to be int in some cases. Many wrbuf_-functions used to return an int
1454 indicating some length.. These return values were never used. And so they
1457 ODR: odr_malloc, odr_total now takes size_t for size.
1459 clone_z_type: fix leak; occurred for encoding failures.
1461 --- 3.0.52 2009/12/03
1463 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1464 bug was introduced in 3.0.51.
1466 --- 3.0.51 2009/12/02
1468 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1470 tcpip comstack: fix leak for getaddrinfo.
1472 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1473 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1474 Decoding of SRU "path" database is performed by private function
1475 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1476 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1478 yaz-client: honor base command for SRU. Change when database setting
1479 is applied for SRU and ensure it is kept when a connection is reset.
1480 Change also the way errors are displayed or SRU (decoding of packages).
1482 --- 3.0.50 2009/11/02
1484 Add support for extra request / response data for SRU codecs and GFS.
1485 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1486 for extra data response buffer and length. For the GFS, both request
1487 and response data (XML) is carried in extra_args and extra_response_data
1488 for the search handler. Patch by Ko van der Sloot.
1490 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1491 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1492 10010). This fixes bug #2113.
1494 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1495 cmdfile included a 'quit' command that would result in a memory violation.
1497 --- 3.0.49 2009/10/01
1499 Make a number of functions defined in xmlquery.c static. These have
1500 never been declared in a public header file (yaz/xmlquery.h) and was
1501 made public by mistake.
1503 Improve speed of character conversions (iconv utilities). This makes
1504 conversions from MARC-8 faster.
1506 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1507 unless type desired is "raw". This will prevent type "xml" from
1508 returning ISO2709 .. Which obviously can not be XML parsed.
1510 Fix memory leak in ZOOM that would occur if option apdulog was used
1511 on a re-used connection.
1513 Frontend server logs HTTP requests.
1515 Frontend server now sends Z39.50 close when it times out (sesssion has
1516 been idle for too long). Versions 2.0.30 and earlier also sent close.
1517 But due to a mistake this was disabled in all versions after that, i.e.
1518 the server would just close the socket immediately.
1520 yaz-client emits a better message when receiving an unrecognised
1521 userInformationField.
1523 Skip zero-length subfields when decoding ISO2709. This rare case happens
1524 if a record has two FS characters in a sequence. Without this patch
1525 there would be a reference beyond char array in using_code_len fragments
1528 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1530 --- 3.0.48 2009/08/28
1532 The show command offered by the zoomsh command now takes a 3d optional
1533 parameter type which is what is passed to ZOOM_record. If the type
1534 argument is omitted, "render" is used.
1536 RPN to CQL conv may use USE string attributes (bug #2978).
1538 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1540 --- 3.0.47 2009/07/08
1542 Function yaz_xml2query allows a diagnostic element in the PQF XML
1543 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1544 code and additional info respectively.
1546 The BER BOOLEAN is now the integral type Odr_bool which still happens
1547 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1548 typedef'd to Odr_int. This is still an integral 'int', but it may be
1549 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1550 ASN-1 compiler as well as programs has been updated to use the new types.
1552 --- 3.0.46 2009/06/08
1554 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1555 only the bibliographic record was rendered. For type=opac, an OPAC
1556 record is only returned if it is present.
1558 iconv: small fix for encoding of advancegreek.
1560 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1562 yaz-client: option auto_reconnect=on really reconnects.
1564 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1566 server: avoid null ptr ref for for yaz_poll errors.
1568 build: fix RPM build for RHEL 5.3.
1570 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1572 --- 3.0.45 2009/03/31
1574 Fixed bug #2709: TCP connect returns Invalid argument.
1576 Fixed compilation for mingw.
1578 Honor charset for raw records (ZOOM_record_get).
1580 Fixed use of errno for threaded mode that was seen on Solaris 10.
1582 Fixed argument passing with blanks in value for Windows Service.
1584 Disable YAZ' own log rotate by default (no 1 GB limit).
1585 The variable l_max_size which specifies the log file limit is set to 0
1586 (DISABLED): This is due to the fact that YAZ is most often deployed using
1587 logrotate. Also YAZ can not perform log rotate because of unsufficient
1588 permissions (setuid).
1590 --- 3.0.44 2009/02/17
1592 List supported encodings in man page for yaz-iconv.
1594 Fixed missing SSL libs for --libs output
1596 Re-established OID record syntax application-xml. Nobody should use it
1597 but we don't want to change soname because of this symbol being absent.
1599 --- 3.0.42 2009/02/02
1601 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1603 Added member named_result_sets for init handler struct for the GFS. This
1604 allows a server to disable named result sets.
1606 Removed OID record syntax application-xml.
1608 Added support for rule-based transliterator for ICU wrapper of YAZ.
1610 Fixed bug #1902: yaz-icu XML output.
1612 Make YAZ checks Emacs friendly.
1614 BITSTRING value shows value. Bug #2346.
1616 ISO2709 decoding: skip control characters from indicator data.
1618 Omit sort key by default in yaz-icu's output.
1620 Allow combined single char options (again) for YAZ' options function.
1622 Utility yaz-marcdump got option to display YAZ version (-V).
1624 Allow YAZ to use ICU 3.4.
1626 Added new ICU test case which illustrates removal of diacritics.
1628 --- 3.0.41 2008/12/29
1630 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1632 --- 3.0.40 2008/12/29
1634 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1637 Fixed bug #2352: yaz-marcdump crashes for certain record.
1639 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1641 Added support for Danmarc2 to UTF-8 conversion.
1643 Added support for ISO5426 to UTF-8 conversion.
1645 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1646 implementation version.
1648 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1650 --- 3.0.38 2008/11/10
1652 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1653 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1655 ZOOM C now interprets databaseName option for ZOOM connection as path
1658 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1660 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1662 Dummy Libxml2 types no longer defined in headers of YAZ'.
1664 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1667 --- 3.0.36 2008/09/26
1669 Various ODR chapter fixes.
1671 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1673 Added missing source for Windows compilation, mutex.c.
1675 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1677 For SRU connections in ZOOM all records up to "count" are now fetched.
1679 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1680 in Windows due to bad error handling for Libxml2.
1682 Added facility for sending arbitrary records (ASN.1 any) using
1683 ZOOM C's Extended service update. Patch by Sam Reynolds.
1685 New options for ZOOM C's connection, logapdu which makes ZOOM log
1688 --- 3.0.34 2008/06/18
1690 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1692 --- 3.0.32 2008/06/12
1694 Fixed memory violation that could occur when decoding UTF-8. This bug
1695 was only present in 3.0.30 of YAZ.
1697 --- 3.0.30 2008/06/06
1699 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1700 GNU TLS is used by default (if found).
1702 yaz-ztest returns OPAC records if a client asks for OPAC.
1704 Improved speed of MARC-8 encoding.
1706 Added support for lossy and loss-less MARC-8 encoding.
1708 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1710 Added new Windows Service wrapper (sc).
1712 yaz-client's itemorder command may now send a file.
1714 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1716 Added new function yaz_log_xml_errors.
1718 Allow (but warn) unknown XML attributes in MARCXML parsing.
1720 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1722 The UTF-8 to MARC-8 conversion now uses a different set of characters
1723 for Greek symbols. Bug #2120.
1725 --- 3.0.26 2008/02/21
1727 Added yaz_daemon (daemon.h).
1729 Fixed bug #2068: pkg-config trouble
1731 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1733 --- 3.0.24 2008/01/28
1735 Document --with-xml2 option.
1737 Added OPAC XML XSD (etc/opacxml.xsd).
1739 Allow glob mask for name attribute in retrieval element for the
1740 generic frontend server's retrieval facility.
1742 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1743 except POLLIN/POLLOUT.
1745 Fixed error handling in cs_listen. Bug #2037.
1747 --- 3.0.22 2008/01/20
1749 Fixed version in yaz/yaz-version.h.
1751 Fixed bug #2027: Crash when closing connection.
1753 Changed configure so that ICU support is only enabled if only ICU
1754 and Libxml2 is available (because the ICU chain is XML based).
1756 --- 3.0.20 2008/01/15
1758 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1759 is built. Only this DLL depends on the ICU runtime.
1761 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1762 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1764 Changed license of CCL module to 'Revised BSD'. After consultation with
1765 remaining members of the original EUROPAGATE consortium, we are re-issuing
1766 the CCL module without a separate license. The software was developed by
1767 Index Data as part of a research project. The special license was included
1768 to help feed usage information back to the project consortium to support
1769 project evaluation. At this time, the project consortium has long-since
1770 disbanded, and the majority of the original principals have retired. At the
1771 same time, we have significantly modified the software during the following
1772 years, to the point where very practically no original code remains. To
1773 simplify re-use of the software, we have contacted those members of the
1774 consortium who could be reached, and agreed to re-issue the module as a
1775 proper part of the YAZ package.
1777 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1779 CQL closer to being version 1.2 compliant. CQL also allows free-form
1780 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1783 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1784 bug could make Extended services handling crash in the ZOOM layer. This
1785 bug was only present in YAZ 3.0.18.
1787 --- 3.0.18 2007/12/19
1789 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1792 yaz-marcdump reads and writes collection wrapped records.
1794 Handle OPAC for record conversion module.
1796 Fixes for ICU wrapper.
1798 Allow ICU libs to be controlled with --with-icu .
1800 --- 3.0.16 2007/11/12
1802 Added yaz_poll which is a wrapper for select/poll. When poll is available
1803 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1804 sockets to be in use.
1806 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1807 functionality through an XML based configuration (ICU chain). This system
1808 is useful for search facilities such as Pazpar2 and Zebra that needs to
1809 perform tokenization of indexed material. The ICU code in a separate
1810 library libyaz3_icu.a.
1812 Added HTTP tunnel facility for COMSTACK, bug #1752.
1813 This is a facility that allows a Web proxy, such as squid, to tunnel
1814 Z39.50 traffic. This facility is "transparent" to must applications
1815 using YAZ. It's enabled by using pseudo transport connect: followed by
1816 the proxy address, followed by command, then follwed by he regular
1817 "virtual" addresss. For example,
1818 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1820 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1822 --- 3.0.14 2007/09/21
1824 Fixed bad memory reference in ZOOM_record - cuased by member not being
1825 initialized. This was a problem only in YAZ 3.0.12.
1827 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1828 fields were not removed.
1830 Changed the way C code is generated from codetables.xml. Made a MARC-8
1831 conversion trie for each characterSet section rather than codeTable.
1832 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1833 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1835 --- 3.0.12 2007/09/12
1837 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1838 from ZOOM_record_error).
1840 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1842 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1844 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1846 Better SRW-to-Bib-1 diagnostic mapping.
1848 ZOOM C and yaz-client announces SRU version 1.2 by default.
1850 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1853 Fixed in yaz_sru_decode to allow other version than 1.1.
1855 --- 3.0.10 2007/08/22
1857 Added support for SRU scan for ZOOM.
1859 Added support for the use of the older versions or Extended Service
1860 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1861 set to the version , 1=first, 2=second, 3=third. The third version is
1862 what ZOOM C has used so far. And that, obviously, is the default.
1864 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1865 therefore in Zebra and in SimpleServer-based applications). The new
1866 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1867 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1868 which is passed into the back-end search callback function.
1870 Added support for HTTP Basic authentication in clients: the SRU/W
1871 codec encodes the username/password elements of the PDU structure
1872 appropriately, and these may be set using the "user" and "password"
1873 options in ZOOM-C applications (the same options that are used for
1874 Z39.50 authentication).
1876 --- 3.0.8 2007/06/25
1878 Fixed bug #1208: SSL appears to be broken in ZOOM.
1880 Fixed bug #1206: Libxml2 include path weirdness.
1882 Added oid_name_to_dotstring.
1884 Allow elementSetName to be specified for ZOOM C record update.
1886 Allow waitAction to be specified for ZOOM C based for Extended Services.
1888 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1889 syntax OID. Bug introduced in YAZ 3 series.
1891 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1893 --- 3.0.6 2007/06/06
1895 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1896 directory. yaz-client now reads commands from file given by option -f
1897 if specified; then tries to read .yazclientrc in current directory.
1898 Failing that, it reads .yazclientrc from user's home directory.
1900 Added support for correlationInfo Note and ID for Record Update via
1903 Added yaz-client command querycharset which specifies character set for
1904 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1905 (termListAndStartPoint).
1907 Charset ISO5428:1984 is an alias for ISO5428-1984.
1909 Implemented a way to perform scan in a result set using Z39.50. This
1910 is achieved by attaching the result set name in the characterInfo
1911 (type InternationalString) of OtherInformation in the Scan Request PDU.
1912 The result set is identified in the otherinformation by the new OID:
1913 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1914 This allows for scan in result set and faceted search . Zebra did some
1915 of this in the APT term using attribute type 8 and value being result
1916 set. Using the OtherInformation approach for this is cleaner and easier
1917 to work with in proxies and the like. This facility can be used in
1918 yaz-client using new command setscan which takes a result set as first
1919 argument, start position (APT) as second.
1921 Changed decoding of SRU XML packed records to deal with servers that
1922 have recordData with XML data with multiple root nodes. Also make
1923 comparison for recordPacking case insensitive. Again, one server
1924 returns "XML" where others return "xml".
1926 For SRU responses allow Content-Type application/xml as well as text/xml.
1928 --- 3.0.4 2007/05/21
1930 Fixed bug in character set conversion of BER strings. Bug introduced
1933 --- 3.0.2 2007/05/08
1935 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1937 For OID class, use oid_class consistently.
1939 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1942 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1943 character set for bibliographic information interchange". By Giannis Kosmas.
1945 Added documentation on new OID API.
1947 --- 3.0.0 2007/05/02
1949 Changes to generic frontend server interface: added new member
1950 'query_charset' for bend_initrequest structure. A backend init handler
1951 should set this member to its native character set for query terms.
1952 When defined, the frontend server logic will announce this character set
1953 to a client if the negotiationModel bit is set by the client. All server
1954 implementors are encouraged to specify this. If a backend server does not
1955 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1957 Added CCL utility to remove terms (stop words) from resulting RPN
1958 tree. This is handled by functions with prefix ccl_stop_words_ .
1960 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1961 terms in RPN queries.
1963 Clean-up the CCL API. Moved some internal structures from ccl.h to
1964 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1965 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1966 This is replaced by ccl_parser_find_str which takes a string instead.
1968 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1969 libyaz.la is the core of YAZ except the generic frontend server and
1970 does not depend on POSIX threads anymore. libyaz_server.la is the
1971 generic frontend server facilities and uses POSIX thread functionality
1972 if available. The libyaz.la no longer depends on POSIX threads because
1973 the number of global structures is limited. NMEM no longer re-uses blocks
1974 between threads ; it simply free's memory immediately but allocates in
1975 "large" chunks as usual. We don't expect any performance penalties
1976 because of this. The yaz_log system is still using a global log_level so
1977 caution must be taken when modifying it with yaz_log_init_.. +
1978 yaz_log_mask_str. This, however, should not cause any trouble because
1979 these functions are called during initialization of application code
1980 anyway. `yaz-config --libs server` returns libs for server applications;
1981 `yaz-config --libs` returns libs for non-server applications.
1983 New OID database - with public definitions in oid_db.h. Removed old OID
1984 database including the head oid.h and definitions such as enum oid_value
1985 and struct oident. The new OID database uses the same string names as
1986 before but the 'protocol' is gone. There are now only two representations
1987 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1988 converts from string to OID; functions with prefix yaz_oid_to_string
1989 converts the other way.
1991 Change to emit_term() in CQL-to-PQF query translation: when a term has
1992 the /regexp relation modifier, do not process it for leading and
1993 trailing "^" and "*", which have quite different meanings in regular
1996 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1997 write handlers no longer carries a 'last' parameter. This will make
1998 yaz_iconv flush "less" characters. A flush is performed by call to
1999 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2001 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2002 removed, because function yaz_query_to_wrbuf does the same.
2004 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2005 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2007 Deprecated MARC utility functions removed.
2009 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2012 Branch split: YAZ_2_1_55_branch
2014 --- 2.1.54 2007/03/16
2016 Fix to ZOOM-C so that transparent reconnection is properly handled on
2017 connections that are in asynchronous mode.
2019 Fixed compilation on OpenBSD 4.0.
2021 Large strings in GRS-1 records are now properly displayed in yaz-client.
2023 Added character conversion support for "advancegreek"; based on patch from
2026 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2027 sequence is met. Before the error was not set so it would be unknown.
2029 Adjust yaz-marcdump MARC reader so that it skips until record separator
2032 --- 2.1.52 2007/03/07
2034 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2035 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2036 fd_set structure used as a bitmask for the FDs to be selected on.
2038 Using ACX_PTHREAD macro to check for POSIX threads.
2040 Fixed have-vsnprintf check.
2042 --- 2.1.50 2007/02/23
2044 Fixes for configure on BSD. Bug #900.
2046 Added snprintf/vsnprintf wrappers for systems that don't have
2047 limits (heavens forbid).
2049 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2050 created before all previous tasks were completed and removed from the
2051 task queue, the new task could be removed by a mistake.
2053 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2055 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2057 Fixed bug #832: Problem with MARC/charset in yaz-client.
2059 Fixed bug #668: save command line history for yaz-client.
2061 Fixed bug #830: pkg-config support.
2063 --- 2.1.48 2007/01/23
2065 Extended ZOOM result set options with two options that may be read by
2066 a client: resultSetStatus and presentStatus with values as specified for
2068 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2070 Fixed bug #827: Using SSL fails on Debian etch.
2072 Fixed bug #826: Weird looking chars for set of MARC records.
2074 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2075 that is treated as an ItemOrder with itemRequest being an XML document
2076 external. The value of "doc" is the content.
2078 Extended the GFS search facility. New member of bend_search_rr
2079 'estimated_hit_count' signals that hits is known to be an estmate
2080 (higher or lower than real hit count). New member 'partial_resultset'
2081 signals that the search was partial (hit count is lower or equal than
2082 real hit count). For Z39.50, the information is stored in resultSetStatus
2083 member of SearchResponse APDU. For SRU, the information is signalled
2084 via SRU diagnostic 59: "Result set created with valid partial results
2087 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2089 --- 2.1.46 2007/01/13
2091 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2093 Added ZOOM_connection_peek_event.
2095 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2096 the following new functions:
2097 ZOOM_event_nonblock, ZOOM_connection_process,
2098 ZOOM_connection_get_{socket,mask,timeout},
2099 ZOOM_connection_fire_event_{timeout,socket}.
2100 The existing blocking event handler, ZOOM_event, is a wrapper for the
2101 + blocking ZOOM_event_sys_{poll,select}.
2103 Implemented function ccl_xml_config which parses XML version of CCL
2104 configuration (bug #798).
2106 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2108 Added timings utility (yaz/timing.h)
2110 --- 2.1.44 2007/01/03
2112 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2115 Fixed bug #779: Rotation of apdu.log fails.
2117 Fixed for character set conversions:
2118 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2119 Honor G1 set in MARC-8 decoding.
2121 --- 2.1.42 2006/12/17
2123 Fixed bug #775: char conversion does not handle Alternative UTF-8
2126 Implemented function yaz_marc_read_line which parses MARC line format
2127 records. There is a wealth of formats out there. So far, this function
2128 reads line records produced by yaz_marc_write_line.
2130 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2131 more generic and easier to remember(!) options: -i format and -o format
2132 which specifies input format and output format respectively - where
2133 format is one of "marc", "marcxml", "line", "marcxchange".
2135 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2136 does not print anything except warnings for records.
2138 For yaz-marcdump, added support for MARC split into files (-s) with a given
2141 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2142 spec, at http://www.loc.gov/standards/sru/record-update/
2143 This has changed the binary layout of the following structs:
2144 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2145 bend_update_rr . Patch by Ko van der Sloot.
2147 Added GFS utility function bend_assoc_is_alive which returns 1 if
2148 association is still alive (client is connected); 0 otherwise (client
2149 closed connection). This allows busy servers to stop working for
2152 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2153 been a separate piece of software. This version of ziffy has been modified
2154 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2156 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2158 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2159 Client code may now interrogate options such as "init_opt_sort" to
2160 find out whether the server claims to support various options.
2162 --- 2.1.40 2006/11/27
2164 Added utilities yaz_{set,get}_esn to set/get element set name from
2167 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2168 of YAZ and has been so since YAZ 2.1.10.
2170 Implemented ZOOM_record_error which returns error information for
2171 record (surrogate diagnostic).
2173 --- 2.1.38 2006/10/31
2175 Updates for SRU Update by Ko van der Sloot:
2176 1. Changed name from "operation" to "action"
2177 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2178 versions in the code, marked as 'backward compatible'.
2179 3. Added diagnostics for SRU Update.
2181 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2183 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2185 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2187 For GFS, fixed problem with SRU diagnostic 'First record position out of
2188 range' being issued for 0 hits.
2190 zoomtst10 part of Windows Build.
2192 --- 2.1.36 2006/10/13
2194 Implemented yaz_filepath_comp which splits a path into file path
2195 components (required by Zebra 2.0.3+).
2197 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2198 BSD inspired license until now so this should not have any real impact on
2199 anybody. See http://www.opensource.org/licenses/bsd-license.php
2201 Fixed bug #687: Missing log lines.
2203 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2206 Fixed bug #689: SRU diagnostics to be added.
2208 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2209 whether a connection is idle (no more work do do).
2211 --- 2.1.34 2006/10/04
2213 Change type of optval from long to int for invocation of setsockopt with
2214 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2216 Added support for specifying the max log file size for the Generic
2217 Frontend Server. The size is given with option -r.
2219 --- 2.1.32 2006/09/21
2221 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2223 --- 2.1.30 2006/09/17
2225 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2228 Fixed bug in Generic Frontend Server that could cause a server to stop
2229 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2231 For the generic frontend server, the maximum record size is used as maximum
2232 size of incoming packages (SRU + Z39.50). The value until was previously
2233 only used in Z39.50 Init negotiation and, later, in a session controlled
2234 sizes of records returned. This is controlled using -k option. It can be
2235 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2237 --- 2.1.28 2006/09/04
2239 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2242 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2244 New option for yaz-marcdump -lpos=value which allows setting a portion
2245 of MARC header to a certain value.
2247 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2249 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2250 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2252 --- 2.1.26 2006/08/15
2254 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2257 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2259 --- 2.1.24 2006/08/08
2261 Fixed MARC ISO2709 encoding routines to deal with character set
2264 Minor changes to GFS logging. Database included in search request log
2267 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2268 cached/multiple records.
2270 Shared libraries are built by default on Unix+configure.
2272 Changed cql2pqf transformation to use a different evaluation order. The
2273 new order is: always, relation, structure, position, truncation, index
2274 and relationModifier. Old order was: always, relation, relationModifier,
2275 structure, index, position, truncation. Note that the the latter ones
2276 override former ones for identical attributes.. The new scheme means that
2277 it is possible to override any existing attribute with a relationModifier.
2278 And also that it is possible to override everything for the index rule
2279 (except the ones listed in relationModifier). No order is perfect but this
2280 one, we believe, covers more real cases.. The "always" should have been
2281 called "default", since the attributes there can be overridden with all
2284 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2285 compilation phase, but also for yaz-config --cflags output. This allows
2286 us to have public headers with Libxml2 stuff in them . It should also,
2287 eventually, make Libxml2 checks redundant in packages using YAZ, such
2290 --- 2.1.22 2006/06/15
2292 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2293 stored in uri, message and details.. Previously diagnostics were stored
2294 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2295 compatibility.. but he's probably the only one affected, so.
2297 Added support for CCL, compiled on the client side, in ZOOM-C. This
2298 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2299 input; the resulting query objects can be used for for searching with
2300 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2302 YAZ' configure searches for OpenSSL by default.
2304 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2305 SL_CTX_use_certificate_file. See
2306 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2307 for more info. Thanks to Ko van der Sloot.
2309 --- 2.1.20 2006/06/02
2311 Bug #600: SRU GET, POST support for yaz-client. Introduced
2312 command 'sru' which selects method SOAP/GET/POST.
2314 Allow missingValueAction to be specified for the sortspec string -
2315 function yaz_sort_spec. By default, the missing value action is null.
2316 Use ! to specify "abort". Use = followed by stringvalue to specify default
2319 Ensured that Present-handler (if defined) is called in GFS before any call to
2320 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2321 searchRetrieve requests.
2323 Documentation for YAZ is now based on the Docbook XML/XSLT using
2324 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2325 is no longer depending on jade/openjade or docbook-to-man scripts.
2326 PDF is no longer part of the distribution - but can optionally be
2327 made using DSSSL/jadetex or FOP.
2329 Added retrieval handling support in Generic Frontend Server to support
2330 conversion between MARC/XML as well as XSLTtransforms. See
2331 etc/yazgfs.xml for an example.
2333 Added Authentication support to Generic Frontend Server in SRU
2334 mode. Authentication using HTTP Basic is supported, as is the use
2335 of 'x-username' and 'x-password' parameters in the request itself.
2337 Added support for a new character set MARC8s identical to MARC8 except
2338 that it converts combined characters to single Unicode characters in the
2339 Latin-1 range (when possible).
2341 --- 2.1.18 2006/04/24
2343 ASN.1 compiler 0.4: generates brief Doxygen file header for
2344 generated .h/.c files.
2346 Utility yaz_iconv now supports conversion to MARC-8.
2348 New facilities for the MARC module. The reading - and writing of
2349 content are separate methods for the yaz_marc_t handle. The following
2350 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2351 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2352 format). Write functions have prefix yaz_marc_write_.. The existing
2353 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2354 available. Removed support for OAI-MARC and simplexml (not the
2355 simplexml from PHP5).
2357 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2358 to be returned for this connection.
2360 --- 2.1.16 2006/03/31
2362 Allow multiple languages and charsets to be specified with
2363 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2364 negcharset iso-8859-1,utf-8
2366 Translation of proximity nodes from CQL into PQF now works.
2368 Moved to automake 1.8, 1.9.
2370 Added function yaz_log_set_handler which allows a log handler to be
2371 installed. This handler will be called for all log messages. Output
2372 to file is also produced; but that can be disabled by passing NULL
2373 fname to yaz_log_init_file.
2375 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2377 For SRW (including GFS), accept application/soap+xml as content-type
2380 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2381 produces NO stylesheet reference even if a default stylesheet is specified
2384 --- 2.1.14 2006/03/14
2386 Updated Windows package to include yazd.dll + yazd.lib for the
2387 Development component.
2389 If the environment variable YAZ_LOG is set, then it is used as a
2390 string indicating the default level of logging to use if not
2391 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2392 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2393 used as before. So, for example, to omit warnings from YAZ logging,
2394 export YAZ_LOG=-warn
2396 cql_transform() now map structure and other attributes before indexes,
2397 so that index-specific structures and other attributes can override
2398 defaults. So now a combination of mapping specifications such as:
2400 index.dc.date = 1=date-modified 4=5
2401 does the right thing.
2403 cql_transform() now also respects the "always" mapping specification,
2404 which establishes an initial set of attributes to be used for all
2405 terms except where overridden by more specific attributes associated
2406 with the index, relation or modifier.
2408 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2409 which mode to use; one of "post", "get" or "soap" (SRW, default).
2411 Fixes for yaz_iconv routines: changed trie-based character set conversions
2412 to use only non-negative values for bit fields due to Sun's C compiler not
2413 supporting negative values.
2415 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2416 sequences where not read correctly. Fix by Rustam Usmanov.
2418 Updated win/makefile to use options, settings which makes things
2419 compile with VS C 2005.
2421 --- 2.1.12 2006/02/01
2423 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2425 In ZOOM socket code, use select instead of poll on MacOSX.
2427 ZOOM-C now support client-side compilation of CQL into RPN that is
2428 sent to the server, enabling CQL to be used against all Z39.50
2429 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2430 ZOOM_query object, and submit it using ZOOM_connection_search().
2431 The CQL-to-RPN translation uses a configuration file, the name of
2432 which must be specified in the Connection's "cqlfile" option.
2434 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2435 function, which takes as its start-term parameter a ZOOM_query object
2436 (which may have had either CQL or RPN set into it).
2439 --- 2.1.10 2005/11/29
2441 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2442 GFS to support this as well. Backend handler, bend_srw_update, does the
2443 update work. Code contributed by Ko van der Sloot.
2445 Allow retrieval of Search Result-1 information in ZOOM by the use of
2446 options that are attached to a result set. ZOOM documentation updated
2449 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2450 UTF-8 conversion. Patch by Raj Patel.
2452 Added option -m to GFS to control formatting of timestamps in log file.
2454 Added 'exit' as synonym for 'quit' in yaz-client
2456 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2457 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2458 for the new members. Patch by Ko van der Sloot.
2460 Added support for SRU POST. It is supported for content-type
2461 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2463 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2464 Instead make the library libyaz.la multi-threaded. Threading as a whole
2465 can still be disabled by configure option --disable-threads. Previosly,
2466 with older GLIBCs there were problems with MT libs under Apache. This
2467 has now been fixed a long time ago.
2469 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2472 CQL module modified to be case insensitive for relations/indexes/operations.
2474 Fixed bug in CQL transform code: incorrect value relationModifieder
2477 Added 'show all' command for yaz-client which retrieves all results
2480 Added new yaz-client, xmles, which takes a (private) OID and
2481 a document to be sent as an extended service request.
2483 Describe new yaz-client commands wait_response and set_auto_wait.
2485 Increase TCP/IP listener backlog from 3 (which I am guessing was
2486 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2487 that the socket will queue as many incoming connections as it's able
2488 to handle ongoing connections. In other words, it will never now
2489 refuse a connection that it would be able to handle merely because
2490 it's not got around to accepting() enough of the pending connections
2491 yet. This is the behaviour anyway under Linux, where the listen()
2492 argument is ignored; but not under BSD and on systems such as
2493 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2494 YAZ-based servers should now be uniform across operating systems in
2497 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2498 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2499 This allows yaz-marcdump to read large MARC batches (>2 GB).
2501 Modified all YAZ source files - except the source which is auto-generated
2502 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2505 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2506 corresponding to the existing *_setl() function. These allow option
2507 values containing arbitrary valuues.
2509 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2510 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2511 except that it returns an indicator of whether or not the sort
2512 criterion was accepted (0 for OK, -1 for invalid).
2514 --- 2.1.8 2005/06/07
2516 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2517 MARC output rather than returning "new" buffer.
2519 yaz-client warns about unknown init options.
2521 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2523 --- 2.1.6 2005/05/24
2525 Added support for SRW sort in Generic Frontend Server. Patch
2526 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2527 sortKeys - or NULL if none is provided.
2529 Fixed bug #307: It was impossible to specify indefinite/no timeout
2530 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2533 Added support for multiple languages and charsets to be specified in
2534 ZOOM. Each charset/language is separated by a blank. If negotiation is
2535 in effect in init-response, Option
2536 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2537 Code based on patch by Vasiliy Osadchuk.
2539 Fixed bug #306: infinite recursion that occurred when calling
2540 yaz_log_level_init as the first call (before other log level or
2543 Fixed bug in scan handling in front end server: if preferred-Position-In-
2544 Response was non-present, a NULL pointer referece was performed.
2546 --- 2.1.4 2005/04/26
2548 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2549 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2550 now defined for all those error codes. So instead of putting 109 in
2551 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2552 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2554 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2557 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2559 Program yaz-client now exits and produces an error message if multiple
2560 Z39.50 servers are specified on the command line (none or one allowed
2563 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2566 --- 2.1.2 2005/03/16
2568 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2570 Fixed bug #272: Preserve spacing for CCL terms.
2572 --- 2.1.0 2005/03/14
2574 Added support for virtual hosts and multiple backend servers for
2575 the YAZ frontend server. The configution is XML based and
2576 support specificition of CQL to RPN mappings and explain information.
2577 See section "Virtual Hosts" in the YAZ manual.
2579 Extended OPAC display utility. OPAC display utility renders
2580 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2581 to supplement yaz_marc_decode_wrbuf.
2583 Fixed a bug in MARC decoder that could caused it to crash for some
2584 invalid MARC records. More diagnostics and warnings where added in
2585 XML output (warnings, etc are stored in comments).
2587 --- 2.0.34 2005/02/08
2589 Fixes for UNIX domain sockets. Bug #261.
2591 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2593 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2594 Added yaz_marc_subfield_str which defines subfield lead string which is
2595 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2596 yaz_marc_endline_str which defines end of fields string used in
2597 YAZ_MARC_LINE format. Default string is newline.
2599 Experimental support for MarcXChange. This format can be produced
2600 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2601 http://www.bs.dk/standards/MarcXchange.xsd
2603 Added yaz-client commands scansize that sets maximum number of
2604 entries to be returned by scan.
2606 --- 2.0.32 2005/01/11
2608 Added support for SRW scan in yaz-client and Generic Frontend Server.
2610 * Added whereInList member to SRW Scan Term.
2612 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2614 Fixed NMEM system to return aligned blocks on the smallest boundaries
2615 that are suitably aligned for all possible types on the particular
2616 architecture YAZ is being built for.
2618 --- 2.0.30 2005/01/04
2620 Fixed numerious warnings that was issued with newer versions of GCC.
2622 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2623 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2626 Make YAZ Generic Frontend Server slightly faster.
2628 Enhance (and reduce) logging for Generic Frontend Server.
2630 Revert YAZ log system so that it flushes every write operation
2631 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2633 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2634 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2635 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2636 will effectively disable old definitions.
2638 --- 2.0.28 2004/11/09
2640 Added yaz_log_time_format which specifies log format using
2643 Added yaz_log_module_level which returns mask for a module. Value
2644 is non-zero mask a if module is enabled; zero if disabled.
2646 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2647 in include/yaz/cql.h.
2649 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2651 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2653 Fixed bug #172: RPM builds does not enable SSL.
2655 Doxyfile.in part of dist. Doxyfile generated by configure.
2657 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2658 are given and the corresponding component does not exist.
2660 Extend CCL documentation in YAZ reference. Describe r=r.
2662 --- 2.0.26 2004/10/01
2664 Fixed MARC->MARCXML conversion to properly deal with
2665 fields, subfields, indicators having non-ASCII characters.
2667 Fixed MARC->MARCXML conversion so that ASCII control characters
2668 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2671 Added YAZ GFS support for conversion from Z39.50 surrogate
2672 diagnostics to SRW surrogate diagnostics.
2674 Bug fix: YAZ GFS did not return schema in explainResponse.
2676 --- 2.0.25 2004/09/30
2678 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2679 now converts recordSchema to elementSetName as well as schema URI.
2681 Fixed bug in COMSTACK that prevented HTTP request packages from being
2684 --- 2.0.24 2004/09/29
2686 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2687 does not require white-space before and after the dash in a range, e.g.
2688 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2691 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2692 due to new GCC removing "redundant" code.
2694 Added yaz-client commands scanpos and scanstep that sets preferred
2695 position and step-size for scan.
2697 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2699 Added CCL utility ccl_qual_buf which parses one or more CCL
2700 spec lines in a buffer.
2702 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2703 of name and value - ignoring empty lines and comments.
2705 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2707 Added odr_get_element_path which returns current element path for an
2708 ODR handle. This utility is useful in error handling or user-defined
2711 Added ODR_PRINT utility odr_set_stream which is is a more generic
2712 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2713 to a write function and pointer to close function. The close function - if
2714 non-NULL - will be called during odr_destroy.
2716 Fixed bug in CCL parser where truncation char was not removed from
2717 right side when truncation=both was in effect.
2719 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2722 --- 2.0.23 2004/08/11
2724 Fix buffer overrun in CQL parser when dealing with proximity (%).
2726 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2727 to UTF-8/UCS conversion is now only based on codetables.xml.
2729 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2731 --- 2.0.22 2004/08/06
2733 Add support for more "commit changes" in ZOOM (uses Extended Services).
2735 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2738 Yet another small fix for configure of SSL.
2740 --- 2.0.21 2004/05/14
2742 Fix SSL libs for configure when --with-openssl=DIR is given.
2744 --- 2.0.20 2004/05/10
2746 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2748 SSL comstack now uses yaz.pem certificate file on server side
2749 by default. Certificate filename can be configured by calling
2750 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2752 Fix bug regarding multiple calls to ZOOM_connection_connect.
2754 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2756 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2757 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2759 ZOOM now allows inspection of X509 peer certificate for verification.
2760 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2762 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2763 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2764 as "modular" but it simplifies things.
2766 Added cs_get_peer_certificate to that returns peer X509 PEM.
2768 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2769 NULL if SSL is unavailable.
2771 Documentation about MARC decoding tools.
2773 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2775 --- 2.0.19 2004/03/30
2777 Rename CHANGELOG to NEWS to follow GNU style packing.
2779 Fix bug with missing initialization of member in init_diagnostics.
2780 This bug affects threaded version of GFS server.
2782 --- 2.0.18 2004/03/20
2784 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2787 Ensure zlib.dll is packed with Windows install.
2789 --- 2.0.17 2004/03/17
2791 Fix encoding of xsd:string to use text instead of CDATA.
2793 Fix endless loop in CQL parser with unbalanced ".
2795 Use a more compact way to store MARC-8 conversion tables.
2797 --- 2.0.16 2004/03/16 Debian only
2799 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2802 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2807 --- 2.0.15 2004/03/01
2809 Another fix for decoding of XML packed records.
2811 --- 2.0.14 2004/02/25
2813 Fixes for Chunked encoding. White space not ignored after length spec.
2815 Update NS and use default NS for SRW diagnostic elements.
2817 --- 2.0.13 2004/02/23
2819 Implement ZOOM_resultset_cache_reset which resets record cache.
2821 Implement ZOOM_resultset_sort which sorts a result set.
2823 Implement chunked HTTP transfer.
2825 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2827 --- 2.0.12 2004/02/16
2829 Added member 'schema' to bend_explain_rr structure so that backend
2830 can specify explain record identifier. Defaults to Zeerex 2.0.
2832 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2834 --- 2.0.11 2004/02/16
2836 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2839 Added init command for yaz-client which sends "extra" init request.
2841 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2842 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2844 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2846 Make ZOOM error code for "invalid query".
2848 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2850 --- 2.0.10 2004/02/05
2852 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2855 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2857 Added option -p <file> to make Generic Frontend Server to write PID file.
2859 Added option -D to put Generic Frontend Server in background on its own.
2861 Make ZOOM C recognize option "password". If unset, "pass" is used
2862 (for backwards compatibility).
2864 Fixed a bug in Generic Frontend Server that could make it crash if a
2865 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2868 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2869 Must be issued before open, in order to be in effect.
2871 --- 2.0.9-6 2004/01/12 Debian/Windows
2873 Make the SRU server more picky WRT unknown params, etc.
2875 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2877 New YAZ client command, options, that sets Z39.50 options.
2879 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2880 options from a string of tokens (one token for each option bit).
2882 Update SRW diagnostic code messages.
2884 --- 2.0.9-5 2004/01/07 Debian/Windows
2886 Handle user defined stylesheet for SRW/SRU.
2888 --- 2.0.9-4 2004/01/06 Debian/Windows
2890 Fix bug in decoding of Content-Length.
2892 --- 2.0.9-3 2004/01/06 Debian/Windows
2894 Fix a bug with decoding of XML packed records.
2896 --- 2.0.9-2 2004/01/05 Debian only
2898 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2900 Fix bug in SRW/SRU diagnostics decoding.
2902 --- 2.0.9 2004/01/05
2904 Fixed bug in Generic Frontend Server which could drop records exceeding
2905 preferred message size. Reported and fixed by Irina Dijour.
2907 Fixed calculation of package size for structured records in Generic
2908 Frontend Server. Reported and fixed by Irina Dijour.
2910 Fixed namespace for SRW/SRU diagnostics.
2912 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2914 --- 2.0.8 2003/12/22
2916 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2917 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2920 CQL changes to reflect recent changes to the specification:
2921 * Documentation talks about context sets instead of index sets.
2922 * Documentation talks about indexes instead of qualifiers.
2923 * The CQL-to-PQF transformer's configuration file now uses
2924 "index.set.name = <attributes>" instead of the old form
2925 "qualifier.set.name = <attributes>". (Both forms are still
2926 understood but the latter is deprecated.)
2927 * CQL terms with no explicit index specified are now interpreted as
2928 cql.serverChoice instead of srw.serverChoice (which of course
2929 behaves exactly the same.)
2931 --- 2.0.7 2003/12/16
2933 MARC conversion can now generate ISO2709 output in another
2934 character set. yaz-marcdump uses this facility if you invoke it
2937 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2938 functions from there can be used from C++.
2940 --- 2.0.6 2003/12/04
2942 Frontend server now transfers memory from decoded packages to stream
2945 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2946 references to show up.
2948 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2949 the ZOOM Abstract API. The older names for the same options are still
2950 also supported for the benefit of old applications.
2952 ZOOM-C supports "implementationId" and "implementationVersion" options
2953 to go along with "implementationName". These allow the user code to
2954 specify identification strings to be sent to servers.
2955 Add OID for the new ExtLite attribute set.
2957 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2958 as requested/supplid by Ere Maijala <ere@atp.fi>
2960 For generic frontend server, reverse the order of
2961 "toolkit-supplied / application-supplied" strings sent as implementationId,
2962 Name and Version. Also, remove the spaces around the slash. This brings
2963 the GFS in line with the behaviour of ZOOM-C on the client side.
2965 Add function ZOOM_scanset_display_term.
2967 yaz-client shows scan displayTerm if present.
2969 Utility yaz-iconv is now installed by default along with the man page
2972 Extend configure check for OpenSSL to use pkg-config where available (such
2975 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2976 server to specify uid/gid/mask for socket using the format
2977 unix:[user=uid,][group=gid,][umask=mask,]file=path
2978 If file= is omitted the existing format is assumed, e.g.
2980 in which case the mask is 0666 (rw for everybody).
2982 Major restructure of YAZ source. All source in libyaz is in src directory.
2983 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2984 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2986 Added man page for utility yaz-marcdump (used to be called marcdump).
2987 yaz-marcdump is installed by 'make install'.
2989 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2990 of incoming package failed.
2992 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2994 Change prototype of odr_perror: add const to message string.
2996 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2998 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2999 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3000 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3001 DNS lookup. There should not be any compatibility problems with this
3002 assuming that blocking=1 or 0 is used.
3004 Fix bad reference in UNIX comstack in function cs_addrstr.
3006 Fix for compilation on AIX.
3008 The generic front-end server (server/seshigh.c) now supports returning
3009 Init diagnostics to the client in User-information-field, in
3010 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3013 --- 2.0.4 2003/09/04
3015 Allow any CQL relation (not just all,any,exact,scr).
3017 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3018 that features the same UI.
3020 Implemented command update0 in YAZ client which is equivalent to
3021 update but uses old of Ext Update ASN.1.
3023 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3024 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3025 Previously no OID was used for this info.
3027 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3028 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3029 returns 'malformed search term' otherwise.
3031 SortResponse member resultCount now set to NULL in sort handler of
3034 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3037 Add three new utility functions for translating OIDs between various
3038 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3039 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3040 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3041 char *oid_to_dotstring(const int *oid, char *oidbuf);
3042 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3044 Reverted modifications for ES Update definition for z_IU0Update
3045 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3046 is back to YAZ 2.0.2.
3048 String value attributes for CCL parser.
3050 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3051 which their FirstSearch server returns in Init responses, sometimes
3052 carrying useful diagnostic information when Init fails. This has the
3053 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3054 "z39.50/oclcui.asn", where its definition is somewhat different from
3055 what OCLC document on their web-site, as required to interoperate with
3058 Support for anonymous authentication in yaz-client. Use the command
3061 * Fix the OID of the Index Data-local "admin" Extended Service from
3062 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3063 the 1000, which indicates a locally-defined OID, was a mistake.
3065 --- 2.0.3 2003/06/20
3067 Fix CCL directive @case handling so that it affects string match for
3068 both CCL keywords and qualifiers.
3070 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3071 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3072 Decoder has been updated with ASN.1 changes as listed in
3073 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3074 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3075 z_IUUpdate, remains unchanged.
3077 ZOOM_record_get may now return a record in a specific character set.
3078 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3079 "from" is the character set of record as returned by target. "to" is
3080 the character set to be returned. If omitted, "to" is UTF-8.
3082 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3084 New ODR utility, odr_getelement, which returns name of element for
3085 which encoding/decoding failed.
3087 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3088 in cases where a required element was omitted.
3090 Bug fix: some MARC8 sequences were not converted.
3092 New ZOOM option "step" which specifies number of records to be
3093 retrieved in one chunk. Used in conjunction with "start" and "count".
3095 SRW support for yaz-client. Use scheme http: to use it, e.g.
3098 yaz-client no longer does (un)intelligent character set conversions
3099 by default. Can be enabled with charset and marc_charset commands.
3101 xmalloc trace fix for 64-bit systems such as DEC alpha.
3103 Solaris 2.6 compile fix.
3105 New function, cql_strerror() translates SRW error codes, as returned
3106 by cql_transform_error(), into human-readable English strings. Used
3107 in yaz-client diagnostics when appropriate.
3109 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3110 converts it into a type-1 query which is sent to the server. This
3111 makes CQL available for use with all Z-servers, as opposed to the tiny
3112 minority that can handle CQL queries themselves.
3114 --- 2.0.2 2003/04/28
3116 New Debian package layout similar to the Redhat Package layout.
3118 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3119 and search result respectively.
3121 --- 2.0.1 2003/04/25
3123 Redhat package is now several packages: libyaz (runtime libraries),
3124 libyaz-devel (development and documentation, and yaz (utility programs).
3125 Package spec file by Morten Bogeskov.
3127 New member 'schema' in struct bend_fetch_rr which the name of requested
3128 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3129 handler MAY set this to reflect the schema of the returned record.
3131 New member 'display_term' in struct scan_entry. GFS now sets member entries
3132 and allocates scan entries to be filled by user scan handler. In previous
3133 version, entries member was allocated by the scan handler. That still works,
3134 but the GFS will ignore member display_term - assuming it was NOT set by
3135 the handler. The fact that the GFS now allocates the entries both allows
3136 for new members and makes a scan handler easier to write.
3138 Fix CQL lex buffer overflow.
3140 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3141 SRU default recordPacking is string.
3143 SRU protocol support for frontend server.
3145 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3147 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3149 Added scan for the ZOOM shell (zoomsh).
3153 * String Identifers for Schemas (Amendment 5).
3154 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3155 Old definition for schema
3156 Odr_oid *schema; /* OPT */
3161 Z_InternationalString *uri;
3162 #define Z_Schema_oid 1
3163 #define Z_Schema_uri 2
3166 * resultCount parameter to Sort Response (Amendment 1).
3167 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3169 Support for SRW 1.0 over HTTP. This is an optional feature and
3170 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3173 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3174 on the same port. SRW SearchRetrieveRequests are mapped
3175 to bend_init,bend_search,bend_fetch,bend_close.
3177 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3179 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3180 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3182 ZOOM connections are SRW based if schem http is used for hostname
3183 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3184 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3186 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3187 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3188 distance=n, order=true/false, relation=le, prox unit=word. If
3189 n is omitted, distance 1 is used.
3191 Fixed problem with C compiler include path in wrong order.
3193 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3194 on Solaris. Patch from Ko van der Sloot.
3196 New MARC decode API. All new functions operate on a yaz_marc_t
3197 handle. The most important new functions are: yaz_marc_create,
3198 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3199 decode and destroy respectively. Decoder can produce formats
3200 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3201 include/yaz/marcdisp.h.
3203 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3204 to UTF-8, UCS-32, wchar_t or Latin-1.
3206 * Prototypes for yaz_iconv_-functions moved to separate header
3207 include/yaz/yaz-iconv.h.
3209 Make a few private functions 'static' in unix.c. This prevents
3210 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3212 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3213 are set when Init Response is received.
3215 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3216 but returns diagnostic set as well.
3218 New function yaz_strerror which is a portable wrapper for
3219 strerror/strerror_r/GetLastMessage.
3221 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3222 is returned for MARC. If type is "oai", then OAI MARC is returned.
3224 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3227 --- 1.9.2 2002/11/26
3229 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3231 Fix bad race conditions on SIGTERM and terminate gracefully in
3234 Move retrieval (data1) module to Zebra since nobody seems to be
3237 Add GRS-1 render for ZOOM using same format as yaz-client.
3239 --- 1.9.1 2002/10/05
3241 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3243 Fix broken ESpec handling in data1 module.
3245 SGML reader parses comments and makes them part of the data1 tree.
3247 Added several type casts so that YAZ compiles as C++ code.
3249 ZOOM didn't handle PDU encoding failures properly.
3251 Added more Bib-1 diagnostics (approved extensions).
3253 GNU configure: better check for iconv.
3255 More portable use of accept, getpeername. Check for socklen_t. Use
3256 int/size_t if socklen_t is not defined.
3260 PQF parser rejects bad queries - including those with extra
3261 characters in them. PQF parser used to silently ignore that.
3262 Cleaner API for PQF added, which allows you to get detailed
3263 error information for bad queries (see yaz/pquery.h).
3265 Fixed bug in ZOOM_record_get for type "database".
3267 Implemented mini iconv library supporting conversions between
3268 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3270 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3272 --- 1.8.9 2002/08/20
3274 Fixed ZOOM C record cache so that preferredRecordSyntax and
3275 elementSetName is used to check for already fetched records.
3277 --- 1.8.8 2002/08/02
3279 Added three members in bend_initrequest structure to facilitate
3280 character set negotiation.
3282 Fixed a bug in frontend server that could cause indefinite
3283 loops under rare conditions.
3285 Revised character set utilities (charneg.h) so that encoding
3286 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3288 For PQF, directive @term <type> sets term type for Scan/Search.
3289 Here <type> is general, string, numeric, null. The term type
3290 is inherited - just like @attr.
3292 New call odr_set_charset that sets character set conversion for
3293 international-strings on a ODR stream. Prototype is:
3294 int odr_set_charset(ODR o, const char *to, const char *from);
3295 The InternationalString is still represented as C string in YAZ
3296 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3297 won't). On the protocol level, you can use any encoding.
3299 Support for UNIX sockets in ZOOM.
3301 Solaris recv sometimes returns errno == ENOENT. It is treated as
3302 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3304 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3305 both client and server. Code by Morten Bogeskov.
3307 --- 1.8.7 2002/05/22
3309 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3310 that they can be used directly from Visual Basic. You must recompile
3311 your windows APP if you're using ZOOM.
3313 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3314 Commands "lang" and "charset" sets language and character set respectively.
3315 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3316 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3318 Attributes from multiple CCL fields may be OR'ed rather than merged
3319 using directive "@field or". Fields are still merged by default -
3320 equivalent to "@field merge".
3322 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3325 Fixed bug in zget for parameter ExtendedServicesResponse.
3329 --- 1.8.6 2002/03/25
3331 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3333 Client displays USR.1:SearchResult-1 (hits per term).
3335 Additional Search Info for search in Generic Frontend Server.
3337 Fixed CCL parsing of "field=s".
3339 WIN32 installer - using the excellent NSIS software from nullsoft.
3341 Fixed CCL parsing of "field = - <number>".
3343 Added function yaz_marc_decode that decodes MARC for line mode
3344 display or XML (similar to that used by JZKit).
3346 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3347 Z39.50. But ISO/ILL was, however.
3349 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3350 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3352 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3353 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3355 --- 1.8.5 2002/02/03
3357 New YAZ client features: Command completion and new commands:
3358 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3359 Code provided by Jacob Poulsen.
3361 New call oid_trav, that visits all registered OIDs via callback.
3363 Function ZOOM_record_get now returns const char pointer rather than
3364 void pointer. It saves a lot of type casts.
3366 For YAZ client, command "auth" now allows you to set authentication
3367 in IdPass style. It is enabled when three tokens are given - order
3368 is user, group and password.
3370 Fix memory leaks in MARC record handling for ZOOM.
3372 New option for YAZ client, -k <kilobytes> that sets
3373 maximum record size. Similar to -k option for generic frontend
3374 server and yaz-ztest.
3376 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3378 Prefix query parser reports "fail" when bad attribute set is given.
3380 Fix in MARC decoder. Proximity logging. Fix for attribute set
3381 in scan handler for server. Patches by Shigeru Ishida.
3383 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3386 Configure option --with-openssl=<dir> now works when a directory is
3387 specified. Patch provided by Morten Bogeskov.
3389 New option for YAZ client, -u <auth>, that sets authentication.
3391 ZOOM fix: error information was sometimes "missing", since error
3392 was cleared/reset too when it shouldn't.
3394 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3396 --- 1.8.4 2002/01/04
3398 Scan for ZOOM API. New object ZOOM_scanset. New functions
3399 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3400 ZOOM_scanset_destroy.
3402 New ZOOM function, ZOOM_connection_last_event, that returns type
3403 of last event (such as "receive data", "send data", "apdu received",
3406 New ZOOM option, schema, that specifies schema for retrieval.
3408 New CCL feature. Qualifiers can be aliases for one or more
3409 other qualifiers (if more than one is given, OR is used).
3411 ZOOM uses named result sets if target supports it.
3413 Two new YAZ client commands: . (dot, which sources a script of YAZ
3414 client commands), and ! (to execute shell command.). Implemented
3417 Working on Debian packages.
3419 --- 1.8.3 2001/11/19
3421 YAZ client enables named result sets only if target supports it.
3423 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3425 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3426 with key="host" to get same result.
3428 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3429 Function Z3950_resultset_record(s) returns references to records
3430 "owned" by resultset. To become owner use Z3950_record_clone.
3432 Function z_ext_record handles Extended Services. Thanks to
3435 --- 1.8.2 2001/11/12
3437 CCL Parser fix: ignore token comma when dealing with and-lists.
3439 Documentation updates for COMSTACK.
3441 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3442 Changed prototype Z3950_records. For some functions, int parameters
3443 were changed to size_t.
3445 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3448 New MARC decode/display function, marc_display_exl, which properly rejects
3449 non-ISO2709 records. YAZ client uses it.
3451 --- 1.8.1 2001/10/29
3453 Fix bug: local attribute set wasn't set correctly in PQF strings.
3457 * Old Z39.50 codecs no longer supported.
3459 Added ZOOM C binding. See http://zoom.z3950.org/
3461 Renamed states for COMSTACKs to avoid confusion with events.
3463 Implemented cs_look and proper cs_rcvconnect.
3465 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3467 Configure detects POSIX threads on OpenBSD.
3469 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3470 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3472 When error is returned from present handler, non-surrogate diagnostic
3473 is returned in present response (and fetch handler is no longer called).
3475 * Minor adjustments to pquery parser (PQF). Token characters may be
3476 escaped by using backslash (C-style).
3478 PQF parser allows string attribute values to be specified. For @attr,
3479 non-numeric characters after the equal-sign are treated as strings
3480 (e.g. @attr 9=title).
3482 CCL trunction character may be defined (@truncation in file)
3484 * function zget_ExtendedServicesRequest sets waitAction to
3485 waitIfPossible (was wait).
3487 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3490 CCL operator names may be set in field definition files (CCL_bibset).
3491 See ccl/bib1 for an example.
3493 Fixes in ASN.1 compiler for C++ compatibility.
3495 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3496 and "op_or" to avoid conflict with C++.
3498 Fixed problem with GNU readline detection on Redhat 7.0.
3500 Added step-size for Scan backend handler.
3502 Fixed bug that made the frontend server crash when no attribute
3503 set was specified for scan.
3505 Front-end server automatically switches to original working directory
3506 when installed as an NT service. Previously -w had to be specified to
3509 Added extended attributes for retrieval module (data1), so that data1
3510 records carry d1_readXML/SGML attributes. d1_read also supports
3511 null-data rules ( <tag/>)
3513 On UNIX when POSIX threads are available, a separate library libyazthread
3514 is created. Programmers should link with that library and the yaz library
3515 when using threads. The reason for the split was that some applications
3516 on Linux, such as Apache, doesn't work well when using shared objects that
3519 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3520 (or any frontend server) in SSL mode by specifying ssl: followed by
3521 address. Only tested on UNIX.
3523 Added feature for CCL module. Virtual structure s=al or s=ol generates
3524 and-list and or-list respectively instead of phrase search.
3528 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3529 log_mask_str. This was done to avoid name conflicts with other libraries
3530 (such as other PHP extensions).
3532 Added raw OID member for preferred record syntax (request_format_raw)
3533 and returned record syntax (output_format_raw) for backend fetch method.
3535 Config file yaz-config now accepts options so that it returns specific
3536 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3538 Shared library support for UNIX using GNU libtool.
3540 * Modified backend interface. Request/Response struct's replaced by
3541 one read/write C struct. For example bend_fetchrequest and
3542 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3543 Every handler - even search has to be registered in bend_init
3544 handler. This means that the YAZ library no longer refers to
3545 external functions and it makes it possible to make the whole
3546 thing a single DLL/SO.
3548 Added Segment handler for backend server.
3550 Added Zmbol/Zebra administrative functions to YAZ client.
3552 Threaded frontend server on UNIX (when POSIX Threads are available).
3553 Starting the server with option -T enables multi-threading.
3557 Added configure option --enable-comp/disable-comp to control use
3558 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3559 located in sub directory asn.
3561 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3562 in ${exec_prefix}/bin along with the other programs yaz-client and
3565 GNU automake used to maintain makefiles.
3567 Added several OID's.
3569 Changed retrieval module so that we can load records with no abstract
3570 syntax defined. Tagpaths in these records are fully composed of string
3573 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3577 On UNIX, the generated makefile now supports a proper 'make install'.
3578 The prefix can be set via GNU configure to set the install location
3579 (default is /usr/local).
3581 * YAZ programs client and ztest were renamed to yaz-client and
3582 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3583 locations, such as /usr/bin,/usr/local/bin,etc.
3585 * YAZ Header files were moved from include to include/yaz. YAZ Header
3586 files are referred to as include <yaz/log.h> rather than <log.h>.
3587 The YAZ include path (-I ..) is therefore the same as before. Programmers
3588 should update their #include statements or use -Ipath/include/yaz
3589 instead. The main motivation for doing this change is that YAZ header files
3590 can be installed in "standard" locations /usr/include,/usr/local/include
3591 without introducing conflicts, since ALL YAZ header files are stored
3592 in subdirectory yaz (under /usr/include for example).
3594 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3595 rather than project/workspace files. We switched because project files
3596 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3599 Changed name of logging function, logf, to yaz_log, to prevent name
3600 clash with some math-log functions. The YAZ header log.h defines logf
3601 to yaz_log (#define) so there should be no incompatibilities by this
3604 Added bend_start/bend_stop handlers for server. These handler are
3605 called on start/stop of server. For windows they are called whenever
3606 a service is started/stopped.
3608 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3609 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3610 in util/yc.tcl. The auto-generated C code structures are, in a few
3611 cases, incompatible with the old decoders. There are differences in the
3612 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3613 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3614 The preprocessor variable ASN_COMPILED is defined when the compiled
3615 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3616 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3617 wish to use the old encoders/decoders you can specify --disable-yc
3620 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3621 version so that it supports both new - and old version of DB Update
3623 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3624 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3625 change. The name parameter can be set to 0 in which no name is specified
3626 for the construction. The macros odr_implicit and odr_explicit sets name
3627 parameter to zero for the construction involved. New macros
3628 odr_implicit_tag and odr_explicit_tag are similar to the others,
3629 except that a name parameter is added. For programmers' that don't use
3630 ODR they probably only need to change the call to z_APDU and z_External.
3632 Added access control facility by interfacing the TCP wrapper library.
3633 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3634 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3635 name of the daemon and enables the access control as specified in
3636 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3638 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3639 den Dool <H.M.vdnDool@kub.nl>.
3641 Added reference ID parameter to most functions in server API - refer
3642 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3644 Changed name of ccl library to libccl.a (was ccl.a).
3646 Fixed bug in decoder for Explain (Category TargetInfo).
3648 Added support for GNU readline in client. Thanks to Jacob Poulsen
3649 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3651 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3652 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3653 IMPLEMENTATION! This change was made to the development version before
3654 the ZIG decided to retract the amendment. If any users MUST be
3655 compatible with the original Update definition, PLEASE CONTACT US, and
3656 we will include a separate definition corresponding to the old Update
3657 ES. Note that because of the change to the ASN.1 of the
3658 TaskPackageRecordStructure we cannot define a single structure that
3659 will support both versions.
3661 * Added const modifier to buffer parameter for some ODR/BER encoding
3662 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3663 completeWAIS, odr_dumpBER.
3665 Fixed bug in client.c which caused a crash when a scanResponse didn't
3666 contain positionOfTerm.
3668 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3669 * will cause an error in a client if a non-YAZ target sends both a
3670 * list of Scan entries and non-surrogate diagnostics.
3672 Retrieval module enhancements. Tag sets may be typed in the reference
3673 to it. From the .abs-file the "tagset" directive takes a third optional
3674 integer type for the tag set referenced. From a .tag-file the "include"
3675 directive takes a third optional type as well. The old "type" directive
3676 in the tag set itself is still recognized but acts as the default type
3679 Backend interface change. Individual Scan terms returned from bend_scan
3680 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3681 in include/backend.h.
3683 Retrieval module enhancements. Multiple tag sets and attribute sets may
3684 be specified in abstract syntax specs. Revised the error/warning for
3685 logging messages reported by the retrieval module when reading the
3688 Object Identifier system (oid_..) changed. The API is backwards
3689 compatible but the oid-routines now allocates new OID's when needed.
3690 Raw OID's may be specified in oid_getvalbyname.
3692 YAZ now uses GNU configure to generate Makefile(s).
3694 * Minor changes in some of the member names of DeleteResultSetRequest and
3695 DeleteResultSetResponse. See include/proto.h.
3697 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3698 and added member 'languages' in TargetInfo (which was missing).
3700 Changed the way attribute sets are handled in the retrieval
3701 module. These are now cached, just like the abstract syntaxes
3704 Changed YAZ so that it links with compiled ASN.1.
3706 Added Explain-schema definitions and mapping routines. The following
3707 Explain categories have been implemented: AttributeDetails,
3708 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3710 Fixed minor bug in Windows version of Server Library.
3712 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3714 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3716 Added EXTERNAL: UNIverse Resource Report (non-standard).
3718 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3719 ENUMERATED and SET OF.
3721 * Added 'const' to some of the char pointer arguments for the
3722 functions, data1_read_node, data1_getelementbytagname,
3723 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3726 Fixed bug in data1_insert_taggeddata - the last_child member of
3727 parent wasn't initialised.
3729 * Changed data1_read_record and data1_read_node so that the supplied
3730 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3731 doesn't refer to any parts of the "SGML"-buffer.
3733 Fixed bug in server library (Windows version of statserv_remove).
3735 * Changed code so that it compiles as C++. The type definition
3736 of Odr_fun which is a member of Odr_arm was changed. The result is,
3737 that an explicit typecast is needed for the fun pointer when
3738 using Odr_arm - as in:
3739 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3741 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3743 Implemented the new structured date and time definition as approved
3744 by the ZIG. Added schemaId element to the specificTag in Espec-1
3745 (also approved at the last ZIG). Thanks to RVDM.
3747 Added some Object identifiers (RVDM).
3749 Changed the Update Extended Service (RVDM).
3751 Added command "refid" to client which specifies referenceId for
3752 the following requests.
3754 Implemented extended service handling for server. See ztest.c
3755 for an example as well as backend.h. New handlers are registerd
3756 in the Init handler.
3758 * Changed interface for sort in server.
3760 Added new members to statserv_options_block. It allows a server
3761 to read options from another source than just the command line. Thanks
3762 to Charles Woodfield.
3764 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3765 renamed to zboolean. Some C++ compilers complained about the name.
3767 Minor changes to gils.abs. Added index 's' (sort) on title
3768 and date/time-last-modified.
3770 --- 1.4pl2 1998/1/30
3772 Fixed bug in server library regarding inetd mode (-i). This bug
3773 was introduced by release 1.4.
3775 --- 1.4pl1 1998/1/29
3777 Added sort facility in client and backend server interface.
3779 Fixed problem with dependencies in Makefile(s).
3781 Fixed bugs for encoders/decoders of extended services and
3784 Implemented sub-tree feature for schemas. Sub-trees are
3785 referenced in *.abs-files. See explain.abs for an example
3786 of the use of this feature.
3788 Modified bib1.att; local attributes for ANY didn't include
3789 ANY itself (only affects use of the retrieval module).
3791 Fixed bug in plain SGML reader in function data1_read_node:
3792 tags with prefix "var" was incorrectly interpreted as variants.
3794 Added feature "sub-schemas" to enable references to - and definitions
3795 of - group of elements.
3797 * Removed member parent from type data1_element (in data1.h).
3799 Implemented function odr_nullval() that returns the value of
3802 * Removed member num_children from data1_node (in data1.h).
3804 Made NT service interface part of the server library. The
3805 function statserv_main uses the NT service when required and
3806 calls the statserv_start / statserv_close routines.
3808 Routine zget_SearchRequest and zget_PresentRequest fills
3809 resultSetName/Id member with "default" instead of "Default".
3811 Fixed memory leak in server. Request queue member wasn't freed.
3813 Fixed nmem_exit so that memory is freed.
3817 Revised the CCL parser utility to be thread safe.
3819 Added function, oid_ent_to_oid, to replace the function
3820 oid_getoidbyent, which is not thread safe.
3822 * Added nmem_init and nmem_exit to initialize and release
3823 NMEM resources. Function nmem_init should be called once in the
3824 initial thread before NMEM/ODR is used. statserv.c and client.c
3825 have been changed accordingly. The change was necessary to make
3826 NMEM thread safe. The NMEM memory pool is shared amongst threads
3827 in a process. Unix-based applications will still work fine without
3830 Added NT Services interface for the the Z39.50 (statserv) Server.
3831 Refer to the ztest.c source on the usage.
3833 Windows 95/NT port using MSVC5.0. Project files are included in the
3836 * Defined new 'global' handle for the retrieval (data1) system. The
3837 new handled, data1_handle, describes the state of the data1 system.
3838 This handle is passed as first argument to virtually all
3839 data1 related routines. The functions data1_create and data1_destroy
3840 creates and destroys a data1 handle respectively.
3842 Added ODR encode stream member to all backend request structures
3843 init, search, scan etc. This stream should be used to allocate all
3844 memory used for the response when thread safe operation is needed.
3846 Changed the comstack utility, cs_addstr, to be thread safe. The
3847 returned hostname string returned by the function is now part the
3850 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3851 function. The cs_straddr takes a COMSTACK handle as argument, so this
3852 function must be used after cs_create and before bind/connect.
3853 This function is thread safe.
3855 Moved test server to 'ztest' directory - generic server code still
3856 in 'server' directory.
3858 Made prefix query (pquery.c) utility thread safe.
3860 Added new function modifier YAZ_EXPORT to 'export' public DLL
3861 functions when using windows (see include/yconfig.h).
3863 Added definitions to the OID database (util/oid.c) (RVDM).
3865 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3867 Added call to ccl_rpn_delete in client program.
3869 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3870 release of RPN structure.
3872 Added support for C++, headers uses extern "C" for public definitions.
3873 With input from RVDM.
3875 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3876 Thanks to Ronald van der Meer (RVDM).
3878 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3880 Added support for private extensions to the OID database
3881 (oid_setprivateoids()). Thanks to RVDM.
3883 Added optional, physical ANY (key replication)
3885 Fixed null-reference problem in GRS-1 output filter.
3887 Proximity operator added to Prefix Query Format (PQF).
3889 In test client command "base" accepts multiple databases.
3891 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3895 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3897 Smallish bug-fixes in the new encoders/decoders (explain).
3899 Bug fixed in DeleteRequest.
3901 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3903 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3905 Added SOIF syntax (using private OID for now) to retrieval module and client.
3907 Added Update extended service.
3909 Added SearchResult-1 additional info structure.
3911 Added optional CCL (ISO8777) interpreter as separate module. Available
3914 --- 1.2 1996/6/10 (1st anniversary release)
3916 Added Summary record syntax. Lightly tested.
3918 Added OPAC record syntax. Untested.
3920 Added ResourceReport service encoders/decoders. Untested.
3922 Fixed bug in z_Unit - wrong tagging on unitSystem.
3924 Fixed bug in the DiagRecs decoder.
3926 Added options for max PDU size and session timeout to frontend-server.
3928 Added documentation of query-language parsers and other supporting utilities.
3930 [frontend-server] Added Attribute set to the bend_scanrequest API.
3932 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3933 surrogate diagnostics were generated.
3935 [retrieval] Allow multiple local values for attribute.
3937 [retrieval] Allow multiple attributes per element in .abs files. index type.
3939 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3941 --- 1.1pl2 1996/4/10
3943 Minor changes, mostly specific to Zebra's requirements (retrieval)
3947 Repaired bug in frontend server when running multiple listening
3948 endpoints in dynamic mode.
3950 z_External() now won't break if a known, ASN.1 value comes encapsulated
3951 in an octet-string. The value will pass through unmodified in an Odr_oct.
3953 Added a bit of code to the demo client to decode & display
3954 ASN.1-structured records represented in the octet-aligned branch of
3955 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3957 Added z_ext_getentbyref() to the ASN module. Doc updated.
3959 * Completed the SCAN definition in the ASN module. This may break SCAN
3960 code based on older YAZ-versions at compile-time. The fix is easy -
3963 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3964 under the SCAN definition. Remember to initialize this, server-people.
3966 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3967 that this does not extend to ODR and ASN.
3969 Comstack allows insertion of established socket (primarily for
3970 inetd-operation of servers). Doc updated.
3972 Front-end server can now start from the inetd in TCP mode. Doc
3975 --- 1.0pl4 1996/1/24
3979 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3980 the rank and record number.
3982 Adjustments to the frontend server.
3984 Fixed diagnostic BER dumper. It ignored the file argument.
3988 Various changes to retrieval module.
3990 Changed the union discriminators of the protocol files from enums to
3991 ints paired with #defines.
3993 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3996 *Changed operator in the RPN structure to 'roperator', again to avoid a
3999 Fixed problems in Explain decoders/encoders.
4001 --- 1.0pl2 1995/12/6
4003 Memory bug in log module fixed.
4005 --- 1.0pl1 1995/12/5
4007 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4009 Bug in Explain DatabaseInfo module fixed.
4011 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4015 The shift to v1.0 signals that we now consider the *core* functionality
4016 of YAZ reasonably stable (the core being more or less equivalent to
4017 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4018 tested (Explain not at all - though that will happen soonish).
4020 Minor changes to code to support Windows port.
4022 Various minor changes after we're getting to use GRS-1 & co. more.
4024 Added Espec-1 format.
4026 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4027 of the protocol and it cannot be selected when encoding (maps into 'string'
4028 when decoding). Needed to talk to some servers.
4030 Demo client can request simple element set names.
4032 Added Diagnostic Format encoders/decoders.
4034 Added simple Close handling to frontend server (no hooks for resource
4035 reporting yet), and demonstration client.
4037 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4039 --- 1.0b3 1995/08/24
4041 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4042 handled incorrectly when records were requested in the searchResponse. This
4043 will only affect you if you use the frontend-server.
4045 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4046 Test-client will ask for and print GRS1. Ztest will return dummy records
4049 Added Explain encoders/decoders to the service-level API. Untested.
4051 Added Extended Services: Item Order encoders and decoders to the Service-
4052 level API. Untested. We could use a recent copy of the pertinent bits
4053 of the ILL protocol to add those bits.
4055 Added diagnostic format 1 encoders/decoders to the service-level API.
4058 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4059 odr_cons.c, which causes a more correct output.
4061 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4062 was always set to 0 when no records were requested in the searchRequest.
4064 * Added better external-handling. This shouldn't harm old code that
4065 *encodes* externals. It can break code that looks for a
4066 'single-ASN1-type' representation, since those types that are known
4067 are now decoded immediately. Look at the SUTRS sample code in
4068 seshigh.c and client.c. Documentation updated.
4070 Handling of structured records in bend_fetchresponse. Length -1 marks
4071 structured record, type is deduced from format field.
4073 --- 1.0b2 1995/06/27
4074 Fairly quick maintenance release to add SUTRS support.
4076 Fixed handling of SUTRS records in the demonstration client.
4078 * Added format field to the bend_fetchrequest and bend_fetchresponce
4079 structures of the backend API (frontend server). When the record is
4080 returned, the value of the format field is mapped to an OID. The
4081 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4082 of the record. The special value VAL_NONE in the bend_request means
4083 that no specific format was requested by the client. Documentation
4084 updated accordingly. Test server (ztest) will return a fixed dummy
4085 SUTRS record if your client requests SUTRS.
4087 Documentation updated accordingly.
4089 You can now set external libraries and RANLIB support in the top-level
4093 First public release.
