3 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
5 zoomsh: offer option -a apdulog
6 As we're used to from yaz-client and GFS based servers.
8 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
9 existing setting apdulog takes effect.
11 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
16 Add re-entrant CQL/Solr/RPN query conversion functions.
17 The re-entrant functions are: cql_transform_r,
18 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
19 These have same functionality as cql_transform,
20 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
21 return the additional infomration as WRBUF to make them re-entrant.
23 Remove CQL to Solr conversion and base solr_transform_t on
24 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
25 data structure as cql_transform_t.
27 cql2pqf utility allows RPN to Solr conversion
29 Fix assert in ZOOM when http connect fails YAZ-757
33 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
35 wrbuf_cstr: make it thread safe YAZ-753
37 yaz_log_init_file may take fd=<no> to open log file at the FD given.
41 Offer new utility function zget_AttributeList_use_string.
43 New conversion step, solrmarc, for record conversion module.
47 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
48 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
53 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
54 The standalone ZOOM sort was completely broken since 5.0.13.
56 ZOOM: generate event Connect rather than None for partial connect
57 (in fact getaddrinfo resolving).
59 ZOOM: only supply clientIP for InitRequest. Rather than for all
62 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
64 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
65 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
66 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
68 New "Facets" section in the documentation.
72 Call exsltRegisterAll in yaz_init_globals, so that all applications
73 using YAZ will have EXSLT things enabled.
75 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
77 Update various URLs to the re-organized SRU pages at LoC.
81 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
84 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
85 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
86 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
91 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
95 Fix gcrypt not properly initialized YAZ-740.
99 Describe memcached option for ZOOM.
101 ZOOM: throw present request out of range again YAZ-739
102 Was removed in YAZ 5.0.13.
104 --- 5.0.13 2014/02/18
106 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
107 with localtime_r when threads + fork is used (such as Metaproxy).
109 yaz-config: quote some RHS values (that might include blanks)
111 zoomsh: shows SearchResult-1
113 zoomsh: sortby command
115 zoomsh: use proper list of connections and result sets YAZ-725
117 Avoid yaz_log in sigterm handler for GFS YAZ-737
118 Logging is still performed, but outside sig handler.
120 New ZOOM C feature: result-set caching with memcached. Example:
121 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
123 Remove SSL via OpenSSL support YAZ-732
124 Also deprecate two functions from comstack that aren't working with
125 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
127 Revert "Bison: use %name-prefix directive rather than -p option"
129 --- 5.0.12 2014/01/22
131 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
133 SRU GET/Solr base URLs may hold additional ?args YAZ-729
134 ZOOM option extraArgs already does this, though. It seems useful
135 when dealing with Solr targets to limit by filter, eg.
136 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
138 Remove #fragment for HTTP request encoding YAZ-730
140 Doc: Update list of DLLs/LIBs
142 Doc: update href link to Unix utils and Git.
144 --- 5.0.11 2014/01/15
146 ZOOM: fix "lost connection" problem with servers that uses both squid
147 and another proxy behind it that returns Location headers with relative
150 zoomsh: do not use readline for stdin (no tty) YAZ-724
151 Just use fgets in that case. If the user hits Ctrl-D a new-line
154 zoomsh: empty command ignored YAZ-723
155 rather than performing exit of zoomsh.
157 yaz-url utility offers option -v to enable verbose mode.
159 yaz_url uses yaz_check_location and offers verbose mode.
161 Add new function yaz_check_location.
162 This function gets an absolute URI from Location (HTTP redirect).
164 cookie API: introduce yaz_cookies_reset
166 Update cql.y for newer bison YAZ-720
167 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
168 longer supported. Instead one must use %lex-param and %parse-param .
170 --- 5.0.10 2014/01/09
172 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
175 rpn2solr: support truncation left(2), left&right(3) YAZ-718
177 Mention SRU version 2.0 in yaz-client man page.
181 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
186 Make cs_parse_host public.A
188 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
189 introduced in YAZ 5.0.6.
193 Fix buffer corruption for yaz-ztest record fetch.
197 Allow yaz-ztest to return user-defined records (one record per file).
198 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
200 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
201 Use the stream write instead of odr_printf which has a 4K tmp buffer.
203 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
207 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
208 can read and write this format. For record format JSON, yaz-ztest returns
209 MARC-in-JSON records.
211 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
212 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
216 Improve error reporting for ICU chains YAZ-707
217 Report config element+rule when ICU status is "failure".
219 ZOOM: stop fetching if present response has no records YAZ-710
220 Some targets return less records than their hit count would suggest.
221 This prevents ZOOM from continuing to fetch records if any present
222 response has 0 records in the response.
224 Ensure that GFS calls exit if any listener fails YAZ-710
225 Before, if XML config was in use, it would start the default
230 yaz-ztest: -V shows version (like yaz-client -V)
232 New iconv encoding: danmarc YAZ-692
234 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
236 daemon: only wait for immediate child rather than all children. YAZ-704
238 yaz-client: fix setting of SRU record schema. If scheme was unset, it
239 could lead to invalid memory reference.
243 yaz-ztest returns schema for MARCXML test records. SRU require that
244 recordSchema for records.
246 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
247 instead of non-surrogate diagnostic. This is a per-record failure.
249 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
250 may refer to multiple listeners now. Attribute listenref is a comma separated
253 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
254 option is given for GFS, the dirname of filename (for -f) is used
255 as prefix for options such as cql2rpn, ccl2rpn, etc.
257 Content-Type charset fixes YAZ-701 . Do not inspect charset in
258 Content-Type header for SOAP when decoding SRU. The payload (XML)
259 itself tells what encoding it is. In response, never supply encoding
260 in Content-Type. The response payload (XML) tells what it is (with no
261 encoding in XML it's UTF-8).
263 HTTP decoding: allow blanks in URL paths YAZ-700
267 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
268 and facets. Ensure recordData and recordSchema are always present in
269 record element, because they are required.
271 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
274 Simplify in a lot of places using odr_strdupn.
276 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
280 Increase various buffers in GFS's statserv_options_block
281 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
282 This change makes many type-casts redundant, and, thus simplifies code.
284 Remove last bits of WAIS support.
286 Remove member 'size' from Odr_oct.
288 Slim down the public part of 'struct odr'. Most elements are not part
289 of struct Odr_private.
291 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
292 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
293 In particular facets are supported in both client - and server side.
294 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
295 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
296 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
297 both request/response). This is what a search handler in the GFS
298 will see (regardless of whether operating in SRU mode or Z39.50).
300 Changes to the srw.h (SRU/Solr) definitions include:
301 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
302 (char*), which replace union query and query_type (int). This is because
303 SRU 2.0 supports a queryType parameter. This also means that, to carry
304 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
305 x-pquery=PQFstring (extention parameter). The extension parameter
307 - New element, packing, that has information about SRU
308 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
310 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
312 New element, packing, in Z_SRW_explainRequest.
314 New elements in Z_SRW_scanRequest, queryType and scanClause.
315 These replace query_type and scanClase untion. This is similar to what
318 --- 4.2.69 2013/10/01
320 GFS: log when closing down - at least SIGTERM YAZ-684
321 Also change formatting WRT PID logging a bit.
323 Improve display of MARC records with multi-byte subfield IDs YAZ-695
324 In some rare cases subfield identifiers are multi-byte characters.
325 This will try to deterime length of those and split accordingly.
326 This affects display in line mode as MARCXML/MarcXchange. The encoding
327 of ISO2709 is the same.
329 Change inp argument to const for yaz_read_UTF8_char.
331 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
333 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
335 Better check of marc leader info YAZ-691
336 Problem is that some systems generate MARCXML/MarcXchange with
337 funny headers. These will not work if encoded as ISO2709.
338 Some tests produce new output, due to updated warning messages
340 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
342 yaz-client: display MAB records YAZ-689.
343 Thanks for Heiko Jansen for this patch.
345 New utility z_get_HTTP_Response_server which allows both HTTP server name
346 and HTTP server URL to be given in response.
348 Debian: do not depend on obs tcl8.3.
350 Debian: do not depend on obs libicu36-dev.
352 --- 4.2.68 2013/09/23
354 GFS: pass additionalSearchInfo to search memeber search_input if
355 given. Otherwise pass otherInfo. Request for facets and other search
356 related things will be passed there in future versions of YAZ.
358 New ZOOM setting, authenticationMode, which allows authentication
359 paramters to be encoded in the URL rather than via HTTP Basic auth.
362 rpn2solr: fix nested AND/OR handling. YAZ-685
364 Add comparison routines for some Z-types, such as NamePlusRecord,
365 RPNQuery, Query, RecordComposition and OtherInformation.
367 --- 4.2.67 2013/09/19
369 Don't decode MAB as MARC. Just like we don't attempt to decode
370 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
372 CCL: allow quoted terms for date ranges. YAZ-681
374 Introduce ccl_parser_qual_search. This function makes old function
375 ccl_qual_search, from YAZ 2, available again.
377 Add yaz_facet_list_to_wrbuf. YAZ-683
379 --- 4.2.66 2013/09/11
381 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
382 schema was given for search. YAZ-675
384 Add Solr date range searches. YAZ-621
386 --- 4.2.65 2013/08/22
388 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
390 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
392 ISO2709/MARC parse most octet aligned records; not just those that
393 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
394 MARC parse more records instead of just dumping as is. YAZ-670
396 ZOOM: proper caching for variations of record schema. YAZ-671
398 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
400 --- 4.2.63 2013/07/17
404 --- 4.2.62 2013/07/11
406 New utility z_get_HTTP_Response_details - an extended version of
409 New utility yaz_url_get_error which returns error message of last
410 failed yaz_url_exec call.
412 yaz-url and url functions: allow max HTTP redirects to be controlled.
414 New functions yaz_file_glob2, yaz_xml_include_glob.
415 These functions takes a flags parameter, which, for now only controls
416 whether to fail inclusion of a non-existing file (without glob
417 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
419 --- 4.2.61 2013/06/20
421 For MARC XML parsing, allow record without leader. A fake/default leader
422 is inserted and a warning is tagged with the record.
424 ICU: fix leak in in icu_iter_get_org_info.
426 --- 4.2.60 2013/06/14
428 ICU: fix bug in icu_iter_get_org_info (un-init variable).
430 --- 4.2.59 2013/06/11
432 Implement z_HTTP_header_remove.
434 --- 4.2.58 2013/06/11
436 ICU: Disallow 0 ptrs for some ICU string utilities.
438 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
439 returns original tokens (before normalization).
441 CCL: avoid z39.58/regex truncation when not needed. Apply only the
442 conversion of those masks, when absolutely necessary.
444 CCL: configurable masking character - @mask. Default masking character
447 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
448 full response anyway, so a Transfer-Encoding header will obstruct the
451 --- 4.2.57 2013/05/15
453 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
454 picking a socket. Problem is that some systems has IPV6 support, but
455 we can't create sockets for them, so we pick AF_UNSPEC first.
457 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
458 use content_len to determine resulting Content-Length in HTTP response
459 and NOT Content-Length supplied in headers by user.
461 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
462 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
464 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
467 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
468 with big endian and unsigned char (by default).
470 --- 4.2.56 2013/04/26
472 Fix yaz-client connect (crash in 4.2.55).
474 --- 4.2.55 2013/04/26
476 Fix proxy/host problem for ZOOM that could occur if unix sockets
479 New Debian package libyaz4-dbg.
481 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
482 differently in tcpip_close.
484 --- 4.2.54 2013/04/17
486 Windows installer of YAZ includes YAZ4J as a component.
488 CQL: allow "extra terms" again, by default. Thus, the CQL parser
489 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
490 and earlier. CQL parser may operate in strict mode where queries
491 not conforming to the standard BNF are rejected (syntax error).
492 Whether the CQL parser operates in strict mode is controlled with
493 cql_parser_strict . Strict mode enabled with option -S for utilities
494 cql2pqf and cql2xcql .
496 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
498 --- 4.2.53 2013/04/10
500 New charset, MARC-8c, which is like MARC-8 but allows control characters
501 0x01 through 0x1F, except ESC to be passed through verbatim.
503 Fix a problem with duplicate sub field character in MARC output. Problem
504 happened only when output was MARC-8 encoded.
506 --- 4.2.52 2013/04/03
508 yaz-ztest: Use hash for fake hit count. Before, random number was used.
509 This is problematic for unit tests using yaz-ztest. This patch also makes
510 a hash for CQL queries. For RPN, any term with a leading digit will be
511 treated as pseudu hit count (to force any particular hit count by a client).
513 yaz-ztest: return unique MARC dummy records. Beyond record offset
514 24, the author surname is patched with offset to make all records
517 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
518 on system wide default (/proc/sys/net/ipv6/bindv6only).
519 @4 binds to IPV4 only. @6 binds to IPV6 only.
521 Update CQL API documentation a bit
523 CQL: don't accept extra terms for queries. Makes the CQL parser
524 stricly conformant to the standard.
526 --- 4.2.51 2013/02/12
528 GFS: scan handler gets extra_args from request and may return extra
529 response data . That's for SRU only.
531 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
533 --- 4.2.50 2013/01/30
535 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
537 OPACXML: sync spelling of availabilityDate in XML to that of Schema
538 opaxxml.xsd. The schema had the correct spelling of this member always.
539 The ASN.1 was mis-spelled and still is (API change) - we are
540 not changing this. However, the OPAC to XML conversion had yet
543 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
546 New function, z_ext_record_oid_nmem, which is similar to
547 z_ext_record_oid but takes NMEM rather than ODR
549 --- 4.2.49 2013/01/18
551 ICU: New conversion element 'join' which joins tokens into one
552 with a custom character given by rule attribute.
554 --- 4.2.48 2013/01/10
556 New GFS search member: present_number. This is a hint to the
557 search handler how many records are going to be fetched immediately
558 following search. There's no guarantee that it's going to be the case,
559 since it depends on hit count (for Z39.50 piggyback) and whether errors
562 Make a few functions static (private). The functions getbyte_stream,
563 ungetbyte_stream and yaz_gets are now private. They were never declared
566 yaz-marcdump: exit(5) for serious decoding errors
568 ISO2709 decoding: be more picky WRT header
570 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
571 was only used as to indicate that next-result-set-position should be
573 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
574 Based on patch from Ashley Sanders.
576 Make some functions static/private in PQF parsing. Those functions were
577 never declared in a public header and so should not be in use by
578 applications based on YAZ.
580 --- 4.2.47 2012/11/23
582 ZOOM: special options to control APDU logging.
583 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
584 logging of APDUs until "saveAPDU" option is set again. If logging is
585 already enabled the effect is that current APDU buffer is cleared.
586 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
587 logging (default behavior on new connection).
588 The APDUs sent/received can be obtained by using
589 Using ZOOM_connection_option_get(c, "APDU") or
590 ZOOM_connection_option_getl(c, "APDU", &l).
592 GFS: relay implementation_version from backend
593 From 3.0.40 and later, implementation_version from backend was
594 not used in init response at all.
596 --- 4.2.46 2012/11/15
598 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
599 mode at all. Probably never did.
601 Make a new version of ztest.pem that, at least, is not expired.
603 --- 4.2.45 2012/11/13
605 Fix description of CCL directive 'case'.
607 More tight checking of form arguments (yaz_uri_to_array). Makes
608 YAZ better at rejecting big and/or bad POSTs.
610 SRU decoding does not report more than up to 10 invalid arguments.
612 rpn2cql: less quotes in generated terms. Semantics unchanged, but
613 it's prettier this way.
615 --- 4.2.44 2012/10/25
617 New utility yaz_decode_init_diag. Defined in proto.h.
619 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
620 given for unix local socket.
621 The COMSTACK string for doing so is:
624 unix:/myfile:tcp:localhost:9999/mybase
625 unix:/myfile:localhost:9999/mybase
626 unix:/myfile:http://fakehost/mybase
628 debian: Use dpkg-buildflags in build process.
630 --- 4.2.43 2012/10/19
632 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
633 global's SRU service uses a recordPosition scheme starting from zero.
634 First record's position should be one
635 according to the standard.
637 --- 4.2.42 2012/10/18
639 Allow more namespaces for SRU. This is to allow, for example, an
640 incorrect namespace returned from server
641 http://services.igi-global.com/sru .
643 Minor fixes for compilation on Windows.
645 --- 4.2.41 2012/10/11
647 daemon: log total number of bad signals from child on stop so that it
648 is more easy to spot problems with child worker processes.
650 retrieval: empty backend name attribute omits element set
651 from being used in retrieval.
653 --- 4.2.40 2012/10/04
655 Implement Solr sort strategy "solr", similar to sru11 sorting.
656 This will implement the correct parameters on Solr requst to do
659 --- 4.2.39 2012/09/28
661 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
664 MARC: Extra/missing indicator handled for MARCXML.
665 The indicator length is given in header and is the same for the
666 whole record. If attributes ind1, ind2 are missing, then content
667 character defaults to blank. Extra indicator attributes (beyond)
668 indicator length are treated as an error.
670 Reformat: delete trailing whitespace
672 --- 4.2.38 2012/09/17
674 MARC: fix non-ASCII characters for leader. This is to ensure we can
675 generate XML in UTF-8.
677 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
678 in one node with structure word.
680 --- 4.2.37 2012/09/04
682 yaz-json-parse: JSON output may be pretty printed by using option
685 Increase default value of max message for Z39.50 Init for GFS, ZOOM
686 and yaz-client. Old value was 1 MB. New value is 64 MB.
688 --- 4.2.36 2012/08/22
690 yaz-client: don't display bogus records from SRU servers. Some SRU servers
691 return more records than given by *maximumRecords*. Skipping those in
694 record_render: simplify buffer return handling and fix at least one bad
695 memory reference, that broke the test_embed_record sometimes.
697 Allow http://user:pass@host notation for yaz_url_exec.
699 zoomsh: allow shell command to be executed. Via the system(3) call.
701 yaz_poll: Allow num_fds == 0
703 yaz-client: fix bad encoding of "itemorder item". The itemorder
704 item <no> - command forgot to use length of encoded Item Request
705 package. Error present since YAZ 3.
707 yaz-ztest: fix bad usage of session handle. Bug was introduced when
708 result sets were saved (271a9c83).
710 SRU recordPacking: guess record packing in response rather than looking
711 at the recordPacking element which, OF COURSE, changed semantics in SRU
714 Decode SRU 2.0 responses. The official namespace for responses, according
715 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
716 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
717 nature.com's server, however, usee namespace
718 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
719 we are now using a glob-expr to match up the namespace. ZOOM C and
720 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
721 I can not find a single real example showing the "real" namespace in
722 the documentation from OASIS. The namespace for requests is different
723 from responses, but this is not added to YAZ yet, when we don't encode
726 --- 4.2.35 2012/06/26
728 zoom/record_render: add support for Base64 decoding fo MARC records
729 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
730 which will decode base64 + ISO2709 marc-8 encoded material from text node
733 --- 4.2.34 2012/06/07
735 Add missing definitions ZOOM_resultset_get_facet_field_by_index
736 and ZOOM_resultset_facets_names.
738 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
741 Change APDU dump printing to avoid long leading blanks. For levels 16
742 or larger the level is shown and the indentation is truncated but
743 recursed with modula 8. This makes it still reasonable easy to read
744 - even for nested BER dumps.
746 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
747 return 0 (incomplete package) in case where the BER package was
748 considered too nested (return value of -2).
750 dumpber: lines of level 15 are not indented further. Two spaces per
751 indentation; indentation 15 or more is indented to a fixed indentation
752 and augmented with a level=<no> indication.
754 zoomsh: increase max size of command+args
756 GFS: No limit in RPN buf size in CQL to RPN conversion.
758 --- 4.2.33 2012/05/09
760 New function for daemon utility, yaz_daemon_stop .
762 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
764 --- 4.2.32 2012/04/25
766 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
767 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
769 --- 4.2.31 2012/04/23
771 YAZ daemon utility relays SIGUSR1 to child process.
773 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
774 would result in en empty database list - which in turn would result in
775 encoding failure for search.
777 Fix reading beyond string in yaz_sort_spec.
779 --- 4.2.30 2012/04/11
781 Add two new SRU diagnostics:
782 236: Access to specified database denied
783 1015: Init/AC: Maximum number of simultaneous sessions for Userid
785 Document the very useful ZOOM-C option "apdulog".
787 CQL to RPN: term may be passed through verbatim. This is enabled with
788 truncation.cql . The assumption being that the term is already CQL.
790 --- 4.2.29 2012/03/20
792 record_conv: leader spec may be given for marc element.
793 The leader spec is given as attribute leaderspec for element marc.
794 For example to convert a MARC21 record from MARC-8 to UTF-8:
795 <marc inputformat="marc" outputformat="marc"
796 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
798 record_conv: allow user-XSLT params. For example:
799 <xslt stylesheet="MARC21slim2DC.xsl">
800 <param name="myparameter" value="myvalue"/>
801 <param name="otherparameter" value="othervalue"/>
804 record_conv: fix error handling for missing marc charsets.
806 CQL: fix extra terms in wrong order.
808 --- 4.2.28 2012/03/06
810 record_conv: modify new API for conversion types. The conversion types
811 may be passed in new functions yaz_record_conv_configure_t and
812 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
814 Avoid mixed statement/variable declare; fixes compilation with Visual
817 --- 4.2.27 2012/02/28
819 Add non-standard SRU diagnostic: 235: "Database does not exist".
820 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
821 Update SRU to Bib-1 diagnostic maps accordingly.
823 CCL: add two new diagnostics for unsupported masking. The new
824 diagnostics are: "Embedded truncation not supported" and
825 "Single charcacter mask not supported".
827 --- 4.2.26 2012/02/23
829 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
831 --- 4.2.25 2012/01/11
833 Build YAZ for Ubuntu Oneiric.
835 CCL: allow parantheses for proximity operands. For example CCL query
836 (a) % (b) is now allowed.
838 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
839 marked dead, rather then being destroyed. If not, the session memory is
840 being free'd before the search/scan handler is finished. Also destroy
841 'request' memory in request_release rather than in various places,
842 which resulted in leaks from time to time.
844 --- 4.2.24 2011/12/21
846 cql_sortby_to_sortkeys: honor sort prefix.
848 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
849 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
850 The rpn2cql family of functions now always returns quoted CQL terms.
852 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
854 --- 4.2.23 2011/12/15
856 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
857 sequence is treated as one. For example, &&a=b&&&c& is identical to
860 --- 4.2.22 2011/12/05
862 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
863 APDUs for a connection to a WRBUF.
865 --- 4.2.21 2011/11/23
867 Fix cql_sortby_to_sortkeys. Completely broken before.
869 Make CCL's @truncation work again.
871 --- 4.2.20 2011/11/09
873 New ZOOM connection setting: tproxy. It's like proxy, but does not
874 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
875 to set resolved address + port for a connection outside ZOOM itself.
877 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
879 --- 4.2.19 2011/11/07
881 Fix uninitialized variable in Solr spell support (could cause SEGV
882 for SRU response decoding).
884 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
885 back-end's addinfo through into the ZOOM response addinfo.
887 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
888 they are separated by a colon and a space rather than simply
891 --- 4.2.18 2011/10/28
893 Add support for Solr spell-checking/suggestions through ZOOM.
894 If a Solr target has been configured correctly for spelling-checking
895 and suggestions, these will now be returned on the ResultSet option
896 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
898 --- 4.2.17 2011/09/28
900 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
901 with a flag whether to substitute escape sequences or not.
903 --- 4.2.16 2011/09/22
905 Fix nmem_strsplit_escape to substitute escape char properly.
907 New option for zoomsh -e , which makes it abort on first error and
908 return process exit code to indicate success/failure.
910 YAZ options utility supports special option -- which makes all it treat
911 all following arguments as non-options.
913 --- 4.2.15 2011/09/16
915 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
916 searched if absolute filename is given.
918 Fix conv_xslt() error-reporting when stylesheet is not found.
919 (The value of fullpath is meaningless in this situation.)
921 --- 4.2.14 2011/09/07
923 Fix problem in CQL sort node creation: un-initialized memory.
925 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
926 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
927 CQL sortby depending on whether Type-1 or CQL is actually sent to the
930 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
931 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
933 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
934 will make it possible to use both single-character mask (#) and wildcard (?)
935 in CCL . Throw diagnostic for left truncation because that is not supported
938 --- 4.2.13 2011/09/01
940 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
941 cases using escapes (\-sequences) and masking.
943 PQF parse fix: A trailing backslash followed by end-of-string (\0)
944 would result in a read one byte beyond string.
946 rpn2ccl may use Z39.50 masking for terms (t=z).
948 ICU check fix. Don't include library -lCrun on Solaris, unless present.
950 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
951 not --cppflags (which seeems like an error in icu-config).
953 --- 4.2.12 2011/08/27 RPM package only
955 cql2ccl: fix conversion of terms: operator characters were not
958 --- 4.2.11 2011/08/25 RPM package only
960 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
961 CCL parser will map both # and ? to their regular expression
962 quivalents (. and .*).
964 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
965 of reserved CQL characters.
967 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
968 is, so that they are passed through.
970 --- 4.2.10 2011/08/24
972 ZOOM SRU mode: more aggressive re-connect.
974 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
975 made available as a utility function, declared in <yaz/logrpn.h>
977 rpn2cql_structure() supports proximity nodes (except that the Type-1
978 proximity node's "exclusion" binary is ignored, as there is no way to
979 express that in CQL). Fixes bug #4564.
983 Fix SEGV that could occur if set command of zoomsh was given without
984 value (2nd argument).
986 Fix SEGV that could occur if unsupported transport was given for
987 COMSTACK - say https (when SSL was unavailable).
989 Build yaz-url on Windows too.
993 New utility to get web content. Header is url.h. A command line tool
994 yaz-url is part of the distribution and packages.
996 Fixes for SSL COMSTACK (when gnutls is in use).
998 New functions yaz_base64{encode,decode}. Header is base64.h.
1000 --- 4.2.7 2011/08/03
1002 ZOOM C includes HTTP response buffer as additional info if it fails
1003 to decode the SRU response.
1005 Make wrbuf_json_puts available.
1007 --- 4.2.6 2011/07/28
1009 zoom: throw diagnostic for invalid value for option "sru". Before a
1010 bad SRU request was sent.
1012 Adding new utility wrbuf_vp_puts.
1014 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1016 --- 4.2.5 2011/07/21
1018 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1019 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1020 redirect was used at the same time.
1022 MARC line mode decoding: be less picky about length given - first
1023 5 digits of header that is.
1025 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1027 Changes to decoding of SRU records: a record with recordPacking=xml is
1028 modified with a new root element <yaz_record> if the recordData contains
1029 multiple children elements. This is to make the record XML parseable
1032 RPN to Solr conversion: encode special characters.
1034 Generic Frontend Server: fix uinitialized member, stepSize.
1036 --- 4.2.4 2011/06/21
1038 Fix a bug in SRU decoding of records.. The database records stored
1039 had un-initialized memory, but it would only be seen with yaz_record_render
1040 and type_spec="ext" .
1042 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1044 --- 4.2.3 2011/06/17
1046 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1048 --- 4.2.2 2011/06/10
1050 Add new utilities to convert from CQL to CCL . These utilities have
1051 prefix cql_to_ccl defined in cql.h.
1053 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1054 lead to memory heap corruptions when ICU utilities were in use.
1056 --- 4.2.1 2011/06/07
1058 Make compilation work without Libxml2.
1060 yaz-client: remove redundant blanks in display of searchResult-1 term
1063 --- 4.2.0 2011/05/18
1065 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1066 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1068 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1069 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1070 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1071 Note that the CQL sortby spec is only converted when the GFS is already
1072 converting from CQL to RPN (cql2rpn element).
1074 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1075 specify whether to collapse delimitors or not. The existing nmem_strsplit
1076 do collapse (collapse parameter = 1).
1078 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1080 Rename internal func yaz_use_attribute_create. While non-static, this
1081 function is not declared in a public header.
1083 --- 4.1.7 2011/03/15
1085 Add -lCrun when linking with ICU on Solaris.
1087 More quicks character set conversions for OPAC records.
1089 --- 4.1.6 2011/03/10
1091 fix problem with record_render: records were converted (character set
1092 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1094 --- 4.1.5 2011/03/08
1096 SRU: add methods for handling DADS SRU-proxy facets.
1098 Separate OPAC record character set for ZOOM_record. yaz_record_render
1099 allows a character set given as charset=from/opacfrom,to where 'from' is
1100 the character set of a bibliographic record, 'opacfrom' is character set
1101 of OPAC record and 'to' is the target character set.
1103 --- 4.1.4 2011/02/21
1105 yaz-client: show may XML format records. Command show followed by 'format'
1106 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1109 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1112 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1114 --- 4.1.3 2011/01/27
1115 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1117 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1118 this package can be distinguished from other vendors.
1120 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1121 as determined by configure
1123 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1125 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1126 returns no error and no record, the present request is considered
1127 partial (only a subset of the records could be returned by backend), and
1128 so it is appropriate to set Present Status to partial-4.
1130 --- 4.1.2 2010/11/02
1132 Move yaz-config man pages to section 1.
1134 More documentation about Solr.
1136 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1137 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1138 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1139 peers on some Linux systems. However, in general that does not work
1140 so YAZ can not rely on that to work. Debian changed behavior in this
1141 respect from Debian lenny to Debian squeeze (still testing as of Oct
1143 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1145 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1147 --- 4.1.1 2010/10/05
1149 Fix yaz-config output: echo_source not set correctly by configure.
1151 --- 4.1.0 2010/10/05
1153 Solr Web Service support for yaz-client and ZOOM.
1155 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1157 --- 4.0.12 2010/08/17
1159 Z39.50 facet support. Facet specifications are passed for search in
1160 other-information with ASN.1 as defined in facet.asn and OID
1161 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1162 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1163 3 is limit (number of entries to get in response). yaz-ztest returns
1164 dummy facets if a client asks for them.
1166 --- 4.0.11 2010/07/09
1168 CCL fixes: bug 2895 and bug 3539.
1170 GR1-display: add comma in display - was removed by mistake in
1173 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1175 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1177 --- 4.0.10 2010/06/18
1179 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1180 result set from a connection. The result set will be on its own
1181 thereafter; no operations on it will perform retrievals from a target.
1182 Only cached copies are returned.
1184 ZOOM C:fix case for HTTP servers responding with Connection:close.
1185 Ensure that if there is a current task it is resumed (like fetching
1186 more records in a result set) . Bug #3484.
1188 PQF parser: use odr_atoi for Odr_int (not atoi)
1190 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1191 values that contain any non-digits are treated as string attributes
1192 (previously decoding only checked for leading character ([0-9]). PQF
1193 encoding: attribute string values are not surrounded by double-quotes.
1195 --- 4.0.9 2010/05/21
1197 New utility for managing threads - thread_create.h.
1199 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1200 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1201 but YAZ' implementation do.
1203 Fixes for yaz_cond-functions on Windows 7.
1205 DLL export more symbols.
1207 zoomsh: show record do NOT render opac.
1209 Remove *.la files from Debian and RPM packages.
1211 --- 4.0.8 2010/05/11
1213 Debian package libyaz-dev depends on libgnutls-dev again (was
1214 removed in YAZ 4.0.6, but due to Libtool it is still needed
1215 even though yaz-config do not list libgnutls libs).
1217 ZOOM: Use only one WRBUF for returning string results for
1218 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1220 ZOOM: ZOOM_connection do not use a shared pointer to
1221 ZOOM_resultset after ZOOM_resultset is destructed by
1222 user. Reverts to YAZ 4.0.4 behavior.
1224 --- 4.0.7 2010/05/04
1226 record-conv: fix problem with at least one XSL conversion -
1227 due to probably incorrect usage of XML XSL documents.
1229 --- 4.0.6 2010/04/29
1231 Fix yaz-config for static mode and the use of SSL (gnutls).
1233 --- 4.0.5 2010/04/29
1235 Forward decl timeval struct in mutex.h and gettimeofday.h.
1237 yaz-config: fix 'static' mode linking.
1239 --- 4.0.4 2010/04/28
1241 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1242 are wrappers for pthreads or Windows. For Windows these are put in
1243 a separate DLL: yaz_cond4.
1245 libyaz.la (whole source) is compiled with thread. If thread support
1246 is enabled enabled, all source of YAZ is compiled with treading support.
1247 This allows core utilities such as yaz_log to use thread facilities.
1248 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1249 thread utilities. This commit moves mutex utilities (mutex.c) from
1250 libyaz_server.la to libyaz.la.
1252 yaz-json-parse displays leading text until error.
1254 --- 4.0.3 2010/04/09
1256 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1257 patch from Giannis Kosmas.
1259 SRU: no longer URL encode SRU database. The URL for an SRU server is
1260 a URL and such is alreeady encoded - at least when given with leading
1261 http:// or https://. This reverts behavior to YAZ 3.0.50.
1263 Support for new MARC XML notation TurboMARC which like MARCXML is a
1264 complete representation of MARC/ISO2709.. This one, however, is more
1265 compact and allows for faster processing with XSLT. TurboMARC can be
1266 used in the marcdisp.h API, from the yaz-marcdump utility and from
1269 yaz-ztest can be configured - via the database - to perform certain
1270 delays when it performs operations search, present and single record
1271 fetch. This allows testers to make yaz-ztest act as a real or even slow
1272 Z39.50 server. Refer to the yaz-ztest man pages for details.
1274 --- 4.0.2 2010/03/09
1276 wrbuf_destroy allows NULL WRBUF passed to it.
1278 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1280 Add ZOOM_connection_close.
1282 No fixed size buffers for ZOOM shell - bug #3257.
1284 tstodr: make it work on s390 platform.
1286 New icu iterator-functions. The new icu_iter-functions makes it possible
1287 to use ICU chains from many threads.
1289 yaz-client: better syntax check for show command.
1291 --- 4.0.1 2010/01/26
1293 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1296 New simple local-file XML include facility which allows file glob-patterns.
1297 Refer to yaz/xml_include.h.
1299 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1302 ZOOM_record_get supports new parameter "format" which makes it format XML
1305 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1306 JSONText in ECMA-262) is JSONValue, not JSONObject.
1308 --- 4.0.0 2010/01/20
1310 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1311 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1313 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1314 POSIX/Unix builds .so with major version 4.
1316 Remove old LOG_-defines from log.h. They have been obsolete and
1317 undefined by default for the last 5 years.
1319 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1321 GFS: Remove socket (int *fd) from search_rr handler. The socket
1322 descriptor ptr is a facility that allowed a search handler to supply
1323 a socket which would serve as a callback - when search was complete.
1324 This facility has now been in use for years.
1326 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1327 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1328 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1329 returns 'const char *' rather than 'char *. The returned string is
1330 read-only and should not be modified by applications. COMSTACK cs_close is
1331 now a void function - it no longer returns int. No applications check for
1332 the value and the implementations has always returned 0.
1334 ZOOM: use size_t for scan hit counts and str size. Functions
1335 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1336 occ (hit count) and len (string length) are now of type size_t pointer
1337 rather than int pointer. This is to be able to represent large hit counts
1338 and to also just to use the proper type for string length (strlen result).
1340 New JSON parser. Refer to include/yaz/json.h .
1342 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1343 Used to be int in some cases. Many wrbuf_-functions used to return an int
1344 indicating some length.. These return values were never used. And so they
1347 ODR: odr_malloc, odr_total now takes size_t for size.
1349 clone_z_type: fix leak; occurred for encoding failures.
1351 --- 3.0.52 2009/12/03
1353 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1354 bug was introduced in 3.0.51.
1356 --- 3.0.51 2009/12/02
1358 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1360 tcpip comstack: fix leak for getaddrinfo.
1362 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1363 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1364 Decoding of SRU "path" database is performed by private function
1365 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1366 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1368 yaz-client: honor base command for SRU. Change when database setting
1369 is applied for SRU and ensure it is kept when a connection is reset.
1370 Change also the way errors are displayed or SRU (decoding of packages).
1372 --- 3.0.50 2009/11/02
1374 Add support for extra request / response data for SRU codecs and GFS.
1375 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1376 for extra data response buffer and length. For the GFS, both request
1377 and response data (XML) is carried in extra_args and extra_response_data
1378 for the search handler. Patch by Ko van der Sloot.
1380 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1381 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1382 10010). This fixes bug #2113.
1384 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1385 cmdfile included a 'quit' command that would result in a memory violation.
1387 --- 3.0.49 2009/10/01
1389 Make a number of functions defined in xmlquery.c static. These have
1390 never been declared in a public header file (yaz/xmlquery.h) and was
1391 made public by mistake.
1393 Improve speed of character conversions (iconv utilities). This makes
1394 conversions from MARC-8 faster.
1396 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1397 unless type desired is "raw". This will prevent type "xml" from
1398 returning ISO2709 .. Which obviously can not be XML parsed.
1400 Fix memory leak in ZOOM that would occur if option apdulog was used
1401 on a re-used connection.
1403 Frontend server logs HTTP requests.
1405 Frontend server now sends Z39.50 close when it times out (sesssion has
1406 been idle for too long). Versions 2.0.30 and earlier also sent close.
1407 But due to a mistake this was disabled in all versions after that, i.e.
1408 the server would just close the socket immediately.
1410 yaz-client emits a better message when receiving an unrecognised
1411 userInformationField.
1413 Skip zero-length subfields when decoding ISO2709. This rare case happens
1414 if a record has two FS characters in a sequence. Without this patch
1415 there would be a reference beyond char array in using_code_len fragments
1418 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1420 --- 3.0.48 2009/08/28
1422 The show command offered by the zoomsh command now takes a 3d optional
1423 parameter type which is what is passed to ZOOM_record. If the type
1424 argument is omitted, "render" is used.
1426 RPN to CQL conv may use USE string attributes (bug #2978).
1428 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1430 --- 3.0.47 2009/07/08
1432 Function yaz_xml2query allows a diagnostic element in the PQF XML
1433 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1434 code and additional info respectively.
1436 The BER BOOLEAN is now the integral type Odr_bool which still happens
1437 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1438 typedef'd to Odr_int. This is still an integral 'int', but it may be
1439 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1440 ASN-1 compiler as well as programs has been updated to use the new types.
1442 --- 3.0.46 2009/06/08
1444 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1445 only the bibliographic record was rendered. For type=opac, an OPAC
1446 record is only returned if it is present.
1448 iconv: small fix for encoding of advancegreek.
1450 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1452 yaz-client: option auto_reconnect=on really reconnects.
1454 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1456 server: avoid null ptr ref for for yaz_poll errors.
1458 build: fix RPM build for RHEL 5.3.
1460 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1462 --- 3.0.45 2009/03/31
1464 Fixed bug #2709: TCP connect returns Invalid argument.
1466 Fixed compilation for mingw.
1468 Honor charset for raw records (ZOOM_record_get).
1470 Fixed use of errno for threaded mode that was seen on Solaris 10.
1472 Fixed argument passing with blanks in value for Windows Service.
1474 Disable YAZ' own log rotate by default (no 1 GB limit).
1475 The variable l_max_size which specifies the log file limit is set to 0
1476 (DISABLED): This is due to the fact that YAZ is most often deployed using
1477 logrotate. Also YAZ can not perform log rotate because of unsufficient
1478 permissions (setuid).
1480 --- 3.0.44 2009/02/17
1482 List supported encodings in man page for yaz-iconv.
1484 Fixed missing SSL libs for --libs output
1486 Re-established OID record syntax application-xml. Nobody should use it
1487 but we don't want to change soname because of this symbol being absent.
1489 --- 3.0.42 2009/02/02
1491 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1493 Added member named_result_sets for init handler struct for the GFS. This
1494 allows a server to disable named result sets.
1496 Removed OID record syntax application-xml.
1498 Added support for rule-based transliterator for ICU wrapper of YAZ.
1500 Fixed bug #1902: yaz-icu XML output.
1502 Make YAZ checks Emacs friendly.
1504 BITSTRING value shows value. Bug #2346.
1506 ISO2709 decoding: skip control characters from indicator data.
1508 Omit sort key by default in yaz-icu's output.
1510 Allow combined single char options (again) for YAZ' options function.
1512 Utility yaz-marcdump got option to display YAZ version (-V).
1514 Allow YAZ to use ICU 3.4.
1516 Added new ICU test case which illustrates removal of diacritics.
1518 --- 3.0.41 2008/12/29
1520 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1522 --- 3.0.40 2008/12/29
1524 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1527 Fixed bug #2352: yaz-marcdump crashes for certain record.
1529 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1531 Added support for Danmarc2 to UTF-8 conversion.
1533 Added support for ISO5426 to UTF-8 conversion.
1535 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1536 implementation version.
1538 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1540 --- 3.0.38 2008/11/10
1542 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1543 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1545 ZOOM C now interprets databaseName option for ZOOM connection as path
1548 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1550 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1552 Dummy Libxml2 types no longer defined in headers of YAZ'.
1554 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1557 --- 3.0.36 2008/09/26
1559 Various ODR chapter fixes.
1561 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1563 Added missing source for Windows compilation, mutex.c.
1565 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1567 For SRU connections in ZOOM all records up to "count" are now fetched.
1569 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1570 in Windows due to bad error handling for Libxml2.
1572 Added facility for sending arbitrary records (ASN.1 any) using
1573 ZOOM C's Extended service update. Patch by Sam Reynolds.
1575 New options for ZOOM C's connection, logapdu which makes ZOOM log
1578 --- 3.0.34 2008/06/18
1580 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1582 --- 3.0.32 2008/06/12
1584 Fixed memory violation that could occur when decoding UTF-8. This bug
1585 was only present in 3.0.30 of YAZ.
1587 --- 3.0.30 2008/06/06
1589 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1590 GNU TLS is used by default (if found).
1592 yaz-ztest returns OPAC records if a client asks for OPAC.
1594 Improved speed of MARC-8 encoding.
1596 Added support for lossy and loss-less MARC-8 encoding.
1598 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1600 Added new Windows Service wrapper (sc).
1602 yaz-client's itemorder command may now send a file.
1604 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1606 Added new function yaz_log_xml_errors.
1608 Allow (but warn) unknown XML attributes in MARCXML parsing.
1610 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1612 The UTF-8 to MARC-8 conversion now uses a different set of characters
1613 for Greek symbols. Bug #2120.
1615 --- 3.0.26 2008/02/21
1617 Added yaz_daemon (daemon.h).
1619 Fixed bug #2068: pkg-config trouble
1621 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1623 --- 3.0.24 2008/01/28
1625 Document --with-xml2 option.
1627 Added OPAC XML XSD (etc/opacxml.xsd).
1629 Allow glob mask for name attribute in retrieval element for the
1630 generic frontend server's retrieval facility.
1632 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1633 except POLLIN/POLLOUT.
1635 Fixed error handling in cs_listen. Bug #2037.
1637 --- 3.0.22 2008/01/20
1639 Fixed version in yaz/yaz-version.h.
1641 Fixed bug #2027: Crash when closing connection.
1643 Changed configure so that ICU support is only enabled if only ICU
1644 and Libxml2 is available (because the ICU chain is XML based).
1646 --- 3.0.20 2008/01/15
1648 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1649 is built. Only this DLL depends on the ICU runtime.
1651 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1652 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1654 Changed license of CCL module to 'Revised BSD'. After consultation with
1655 remaining members of the original EUROPAGATE consortium, we are re-issuing
1656 the CCL module without a separate license. The software was developed by
1657 Index Data as part of a research project. The special license was included
1658 to help feed usage information back to the project consortium to support
1659 project evaluation. At this time, the project consortium has long-since
1660 disbanded, and the majority of the original principals have retired. At the
1661 same time, we have significantly modified the software during the following
1662 years, to the point where very practically no original code remains. To
1663 simplify re-use of the software, we have contacted those members of the
1664 consortium who could be reached, and agreed to re-issue the module as a
1665 proper part of the YAZ package.
1667 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1669 CQL closer to being version 1.2 compliant. CQL also allows free-form
1670 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1673 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1674 bug could make Extended services handling crash in the ZOOM layer. This
1675 bug was only present in YAZ 3.0.18.
1677 --- 3.0.18 2007/12/19
1679 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1682 yaz-marcdump reads and writes collection wrapped records.
1684 Handle OPAC for record conversion module.
1686 Fixes for ICU wrapper.
1688 Allow ICU libs to be controlled with --with-icu .
1690 --- 3.0.16 2007/11/12
1692 Added yaz_poll which is a wrapper for select/poll. When poll is available
1693 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1694 sockets to be in use.
1696 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1697 functionality through an XML based configuration (ICU chain). This system
1698 is useful for search facilities such as Pazpar2 and Zebra that needs to
1699 perform tokenization of indexed material. The ICU code in a separate
1700 library libyaz3_icu.a.
1702 Added HTTP tunnel facility for COMSTACK, bug #1752.
1703 This is a facility that allows a Web proxy, such as squid, to tunnel
1704 Z39.50 traffic. This facility is "transparent" to must applications
1705 using YAZ. It's enabled by using pseudo transport connect: followed by
1706 the proxy address, followed by command, then follwed by he regular
1707 "virtual" addresss. For example,
1708 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1710 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1712 --- 3.0.14 2007/09/21
1714 Fixed bad memory reference in ZOOM_record - cuased by member not being
1715 initialized. This was a problem only in YAZ 3.0.12.
1717 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1718 fields were not removed.
1720 Changed the way C code is generated from codetables.xml. Made a MARC-8
1721 conversion trie for each characterSet section rather than codeTable.
1722 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1723 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1725 --- 3.0.12 2007/09/12
1727 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1728 from ZOOM_record_error).
1730 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1732 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1734 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1736 Better SRW-to-Bib-1 diagnostic mapping.
1738 ZOOM C and yaz-client announces SRU version 1.2 by default.
1740 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1743 Fixed in yaz_sru_decode to allow other version than 1.1.
1745 --- 3.0.10 2007/08/22
1747 Added support for SRU scan for ZOOM.
1749 Added support for the use of the older versions or Extended Service
1750 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1751 set to the version , 1=first, 2=second, 3=third. The third version is
1752 what ZOOM C has used so far. And that, obviously, is the default.
1754 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1755 therefore in Zebra and in SimpleServer-based applications). The new
1756 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1757 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1758 which is passed into the back-end search callback function.
1760 Added support for HTTP Basic authentication in clients: the SRU/W
1761 codec encodes the username/password elements of the PDU structure
1762 appropriately, and these may be set using the "user" and "password"
1763 options in ZOOM-C applications (the same options that are used for
1764 Z39.50 authentication).
1766 --- 3.0.8 2007/06/25
1768 Fixed bug #1208: SSL appears to be broken in ZOOM.
1770 Fixed bug #1206: Libxml2 include path weirdness.
1772 Added oid_name_to_dotstring.
1774 Allow elementSetName to be specified for ZOOM C record update.
1776 Allow waitAction to be specified for ZOOM C based for Extended Services.
1778 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1779 syntax OID. Bug introduced in YAZ 3 series.
1781 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1783 --- 3.0.6 2007/06/06
1785 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1786 directory. yaz-client now reads commands from file given by option -f
1787 if specified; then tries to read .yazclientrc in current directory.
1788 Failing that, it reads .yazclientrc from user's home directory.
1790 Added support for correlationInfo Note and ID for Record Update via
1793 Added yaz-client command querycharset which specifies character set for
1794 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1795 (termListAndStartPoint).
1797 Charset ISO5428:1984 is an alias for ISO5428-1984.
1799 Implemented a way to perform scan in a result set using Z39.50. This
1800 is achieved by attaching the result set name in the characterInfo
1801 (type InternationalString) of OtherInformation in the Scan Request PDU.
1802 The result set is identified in the otherinformation by the new OID:
1803 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1804 This allows for scan in result set and faceted search . Zebra did some
1805 of this in the APT term using attribute type 8 and value being result
1806 set. Using the OtherInformation approach for this is cleaner and easier
1807 to work with in proxies and the like. This facility can be used in
1808 yaz-client using new command setscan which takes a result set as first
1809 argument, start position (APT) as second.
1811 Changed decoding of SRU XML packed records to deal with servers that
1812 have recordData with XML data with multiple root nodes. Also make
1813 comparison for recordPacking case insensitive. Again, one server
1814 returns "XML" where others return "xml".
1816 For SRU responses allow Content-Type application/xml as well as text/xml.
1818 --- 3.0.4 2007/05/21
1820 Fixed bug in character set conversion of BER strings. Bug introduced
1823 --- 3.0.2 2007/05/08
1825 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1827 For OID class, use oid_class consistently.
1829 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1832 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1833 character set for bibliographic information interchange". By Giannis Kosmas.
1835 Added documentation on new OID API.
1837 --- 3.0.0 2007/05/02
1839 Changes to generic frontend server interface: added new member
1840 'query_charset' for bend_initrequest structure. A backend init handler
1841 should set this member to its native character set for query terms.
1842 When defined, the frontend server logic will announce this character set
1843 to a client if the negotiationModel bit is set by the client. All server
1844 implementors are encouraged to specify this. If a backend server does not
1845 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1847 Added CCL utility to remove terms (stop words) from resulting RPN
1848 tree. This is handled by functions with prefix ccl_stop_words_ .
1850 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1851 terms in RPN queries.
1853 Clean-up the CCL API. Moved some internal structures from ccl.h to
1854 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1855 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1856 This is replaced by ccl_parser_find_str which takes a string instead.
1858 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1859 libyaz.la is the core of YAZ except the generic frontend server and
1860 does not depend on POSIX threads anymore. libyaz_server.la is the
1861 generic frontend server facilities and uses POSIX thread functionality
1862 if available. The libyaz.la no longer depends on POSIX threads because
1863 the number of global structures is limited. NMEM no longer re-uses blocks
1864 between threads ; it simply free's memory immediately but allocates in
1865 "large" chunks as usual. We don't expect any performance penalties
1866 because of this. The yaz_log system is still using a global log_level so
1867 caution must be taken when modifying it with yaz_log_init_.. +
1868 yaz_log_mask_str. This, however, should not cause any trouble because
1869 these functions are called during initialization of application code
1870 anyway. `yaz-config --libs server` returns libs for server applications;
1871 `yaz-config --libs` returns libs for non-server applications.
1873 New OID database - with public definitions in oid_db.h. Removed old OID
1874 database including the head oid.h and definitions such as enum oid_value
1875 and struct oident. The new OID database uses the same string names as
1876 before but the 'protocol' is gone. There are now only two representations
1877 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1878 converts from string to OID; functions with prefix yaz_oid_to_string
1879 converts the other way.
1881 Change to emit_term() in CQL-to-PQF query translation: when a term has
1882 the /regexp relation modifier, do not process it for leading and
1883 trailing "^" and "*", which have quite different meanings in regular
1886 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1887 write handlers no longer carries a 'last' parameter. This will make
1888 yaz_iconv flush "less" characters. A flush is performed by call to
1889 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1891 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1892 removed, because function yaz_query_to_wrbuf does the same.
1894 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1895 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1897 Deprecated MARC utility functions removed.
1899 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1902 Branch split: YAZ_2_1_55_branch
1904 --- 2.1.54 2007/03/16
1906 Fix to ZOOM-C so that transparent reconnection is properly handled on
1907 connections that are in asynchronous mode.
1909 Fixed compilation on OpenBSD 4.0.
1911 Large strings in GRS-1 records are now properly displayed in yaz-client.
1913 Added character conversion support for "advancegreek"; based on patch from
1916 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1917 sequence is met. Before the error was not set so it would be unknown.
1919 Adjust yaz-marcdump MARC reader so that it skips until record separator
1922 --- 2.1.52 2007/03/07
1924 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1925 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1926 fd_set structure used as a bitmask for the FDs to be selected on.
1928 Using ACX_PTHREAD macro to check for POSIX threads.
1930 Fixed have-vsnprintf check.
1932 --- 2.1.50 2007/02/23
1934 Fixes for configure on BSD. Bug #900.
1936 Added snprintf/vsnprintf wrappers for systems that don't have
1937 limits (heavens forbid).
1939 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1940 created before all previous tasks were completed and removed from the
1941 task queue, the new task could be removed by a mistake.
1943 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1945 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1947 Fixed bug #832: Problem with MARC/charset in yaz-client.
1949 Fixed bug #668: save command line history for yaz-client.
1951 Fixed bug #830: pkg-config support.
1953 --- 2.1.48 2007/01/23
1955 Extended ZOOM result set options with two options that may be read by
1956 a client: resultSetStatus and presentStatus with values as specified for
1958 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1960 Fixed bug #827: Using SSL fails on Debian etch.
1962 Fixed bug #826: Weird looking chars for set of MARC records.
1964 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1965 that is treated as an ItemOrder with itemRequest being an XML document
1966 external. The value of "doc" is the content.
1968 Extended the GFS search facility. New member of bend_search_rr
1969 'estimated_hit_count' signals that hits is known to be an estmate
1970 (higher or lower than real hit count). New member 'partial_resultset'
1971 signals that the search was partial (hit count is lower or equal than
1972 real hit count). For Z39.50, the information is stored in resultSetStatus
1973 member of SearchResponse APDU. For SRU, the information is signalled
1974 via SRU diagnostic 59: "Result set created with valid partial results
1977 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1979 --- 2.1.46 2007/01/13
1981 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1983 Added ZOOM_connection_peek_event.
1985 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1986 the following new functions:
1987 ZOOM_event_nonblock, ZOOM_connection_process,
1988 ZOOM_connection_get_{socket,mask,timeout},
1989 ZOOM_connection_fire_event_{timeout,socket}.
1990 The existing blocking event handler, ZOOM_event, is a wrapper for the
1991 + blocking ZOOM_event_sys_{poll,select}.
1993 Implemented function ccl_xml_config which parses XML version of CCL
1994 configuration (bug #798).
1996 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1998 Added timings utility (yaz/timing.h)
2000 --- 2.1.44 2007/01/03
2002 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2005 Fixed bug #779: Rotation of apdu.log fails.
2007 Fixed for character set conversions:
2008 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2009 Honor G1 set in MARC-8 decoding.
2011 --- 2.1.42 2006/12/17
2013 Fixed bug #775: char conversion does not handle Alternative UTF-8
2016 Implemented function yaz_marc_read_line which parses MARC line format
2017 records. There is a wealth of formats out there. So far, this function
2018 reads line records produced by yaz_marc_write_line.
2020 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2021 more generic and easier to remember(!) options: -i format and -o format
2022 which specifies input format and output format respectively - where
2023 format is one of "marc", "marcxml", "line", "marcxchange".
2025 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2026 does not print anything except warnings for records.
2028 For yaz-marcdump, added support for MARC split into files (-s) with a given
2031 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2032 spec, at http://www.loc.gov/standards/sru/record-update/
2033 This has changed the binary layout of the following structs:
2034 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2035 bend_update_rr . Patch by Ko van der Sloot.
2037 Added GFS utility function bend_assoc_is_alive which returns 1 if
2038 association is still alive (client is connected); 0 otherwise (client
2039 closed connection). This allows busy servers to stop working for
2042 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2043 been a separate piece of software. This version of ziffy has been modified
2044 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2046 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2048 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2049 Client code may now interrogate options such as "init_opt_sort" to
2050 find out whether the server claims to support various options.
2052 --- 2.1.40 2006/11/27
2054 Added utilities yaz_{set,get}_esn to set/get element set name from
2057 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2058 of YAZ and has been so since YAZ 2.1.10.
2060 Implemented ZOOM_record_error which returns error information for
2061 record (surrogate diagnostic).
2063 --- 2.1.38 2006/10/31
2065 Updates for SRU Update by Ko van der Sloot:
2066 1. Changed name from "operation" to "action"
2067 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2068 versions in the code, marked as 'backward compatible'.
2069 3. Added diagnostics for SRU Update.
2071 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2073 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2075 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2077 For GFS, fixed problem with SRU diagnostic 'First record position out of
2078 range' being issued for 0 hits.
2080 zoomtst10 part of Windows Build.
2082 --- 2.1.36 2006/10/13
2084 Implemented yaz_filepath_comp which splits a path into file path
2085 components (required by Zebra 2.0.3+).
2087 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2088 BSD inspired license until now so this should not have any real impact on
2089 anybody. See http://www.opensource.org/licenses/bsd-license.php
2091 Fixed bug #687: Missing log lines.
2093 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2096 Fixed bug #689: SRU diagnostics to be added.
2098 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2099 whether a connection is idle (no more work do do).
2101 --- 2.1.34 2006/10/04
2103 Change type of optval from long to int for invocation of setsockopt with
2104 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2106 Added support for specifying the max log file size for the Generic
2107 Frontend Server. The size is given with option -r.
2109 --- 2.1.32 2006/09/21
2111 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2113 --- 2.1.30 2006/09/17
2115 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2118 Fixed bug in Generic Frontend Server that could cause a server to stop
2119 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2121 For the generic frontend server, the maximum record size is used as maximum
2122 size of incoming packages (SRU + Z39.50). The value until was previously
2123 only used in Z39.50 Init negotiation and, later, in a session controlled
2124 sizes of records returned. This is controlled using -k option. It can be
2125 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2127 --- 2.1.28 2006/09/04
2129 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2132 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2134 New option for yaz-marcdump -lpos=value which allows setting a portion
2135 of MARC header to a certain value.
2137 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2139 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2140 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2142 --- 2.1.26 2006/08/15
2144 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2147 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2149 --- 2.1.24 2006/08/08
2151 Fixed MARC ISO2709 encoding routines to deal with character set
2154 Minor changes to GFS logging. Database included in search request log
2157 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2158 cached/multiple records.
2160 Shared libraries are built by default on Unix+configure.
2162 Changed cql2pqf transformation to use a different evaluation order. The
2163 new order is: always, relation, structure, position, truncation, index
2164 and relationModifier. Old order was: always, relation, relationModifier,
2165 structure, index, position, truncation. Note that the the latter ones
2166 override former ones for identical attributes.. The new scheme means that
2167 it is possible to override any existing attribute with a relationModifier.
2168 And also that it is possible to override everything for the index rule
2169 (except the ones listed in relationModifier). No order is perfect but this
2170 one, we believe, covers more real cases.. The "always" should have been
2171 called "default", since the attributes there can be overridden with all
2174 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2175 compilation phase, but also for yaz-config --cflags output. This allows
2176 us to have public headers with Libxml2 stuff in them . It should also,
2177 eventually, make Libxml2 checks redundant in packages using YAZ, such
2180 --- 2.1.22 2006/06/15
2182 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2183 stored in uri, message and details.. Previously diagnostics were stored
2184 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2185 compatibility.. but he's probably the only one affected, so.
2187 Added support for CCL, compiled on the client side, in ZOOM-C. This
2188 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2189 input; the resulting query objects can be used for for searching with
2190 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2192 YAZ' configure searches for OpenSSL by default.
2194 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2195 SL_CTX_use_certificate_file. See
2196 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2197 for more info. Thanks to Ko van der Sloot.
2199 --- 2.1.20 2006/06/02
2201 Bug #600: SRU GET, POST support for yaz-client. Introduced
2202 command 'sru' which selects method SOAP/GET/POST.
2204 Allow missingValueAction to be specified for the sortspec string -
2205 function yaz_sort_spec. By default, the missing value action is null.
2206 Use ! to specify "abort". Use = followed by stringvalue to specify default
2209 Ensured that Present-handler (if defined) is called in GFS before any call to
2210 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2211 searchRetrieve requests.
2213 Documentation for YAZ is now based on the Docbook XML/XSLT using
2214 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2215 is no longer depending on jade/openjade or docbook-to-man scripts.
2216 PDF is no longer part of the distribution - but can optionally be
2217 made using DSSSL/jadetex or FOP.
2219 Added retrieval handling support in Generic Frontend Server to support
2220 conversion between MARC/XML as well as XSLTtransforms. See
2221 etc/yazgfs.xml for an example.
2223 Added Authentication support to Generic Frontend Server in SRU
2224 mode. Authentication using HTTP Basic is supported, as is the use
2225 of 'x-username' and 'x-password' parameters in the request itself.
2227 Added support for a new character set MARC8s identical to MARC8 except
2228 that it converts combined characters to single Unicode characters in the
2229 Latin-1 range (when possible).
2231 --- 2.1.18 2006/04/24
2233 ASN.1 compiler 0.4: generates brief Doxygen file header for
2234 generated .h/.c files.
2236 Utility yaz_iconv now supports conversion to MARC-8.
2238 New facilities for the MARC module. The reading - and writing of
2239 content are separate methods for the yaz_marc_t handle. The following
2240 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2241 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2242 format). Write functions have prefix yaz_marc_write_.. The existing
2243 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2244 available. Removed support for OAI-MARC and simplexml (not the
2245 simplexml from PHP5).
2247 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2248 to be returned for this connection.
2250 --- 2.1.16 2006/03/31
2252 Allow multiple languages and charsets to be specified with
2253 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2254 negcharset iso-8859-1,utf-8
2256 Translation of proximity nodes from CQL into PQF now works.
2258 Moved to automake 1.8, 1.9.
2260 Added function yaz_log_set_handler which allows a log handler to be
2261 installed. This handler will be called for all log messages. Output
2262 to file is also produced; but that can be disabled by passing NULL
2263 fname to yaz_log_init_file.
2265 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2267 For SRW (including GFS), accept application/soap+xml as content-type
2270 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2271 produces NO stylesheet reference even if a default stylesheet is specified
2274 --- 2.1.14 2006/03/14
2276 Updated Windows package to include yazd.dll + yazd.lib for the
2277 Development component.
2279 If the environment variable YAZ_LOG is set, then it is used as a
2280 string indicating the default level of logging to use if not
2281 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2282 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2283 used as before. So, for example, to omit warnings from YAZ logging,
2284 export YAZ_LOG=-warn
2286 cql_transform() now map structure and other attributes before indexes,
2287 so that index-specific structures and other attributes can override
2288 defaults. So now a combination of mapping specifications such as:
2290 index.dc.date = 1=date-modified 4=5
2291 does the right thing.
2293 cql_transform() now also respects the "always" mapping specification,
2294 which establishes an initial set of attributes to be used for all
2295 terms except where overridden by more specific attributes associated
2296 with the index, relation or modifier.
2298 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2299 which mode to use; one of "post", "get" or "soap" (SRW, default).
2301 Fixes for yaz_iconv routines: changed trie-based character set conversions
2302 to use only non-negative values for bit fields due to Sun's C compiler not
2303 supporting negative values.
2305 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2306 sequences where not read correctly. Fix by Rustam Usmanov.
2308 Updated win/makefile to use options, settings which makes things
2309 compile with VS C 2005.
2311 --- 2.1.12 2006/02/01
2313 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2315 In ZOOM socket code, use select instead of poll on MacOSX.
2317 ZOOM-C now support client-side compilation of CQL into RPN that is
2318 sent to the server, enabling CQL to be used against all Z39.50
2319 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2320 ZOOM_query object, and submit it using ZOOM_connection_search().
2321 The CQL-to-RPN translation uses a configuration file, the name of
2322 which must be specified in the Connection's "cqlfile" option.
2324 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2325 function, which takes as its start-term parameter a ZOOM_query object
2326 (which may have had either CQL or RPN set into it).
2329 --- 2.1.10 2005/11/29
2331 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2332 GFS to support this as well. Backend handler, bend_srw_update, does the
2333 update work. Code contributed by Ko van der Sloot.
2335 Allow retrieval of Search Result-1 information in ZOOM by the use of
2336 options that are attached to a result set. ZOOM documentation updated
2339 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2340 UTF-8 conversion. Patch by Raj Patel.
2342 Added option -m to GFS to control formatting of timestamps in log file.
2344 Added 'exit' as synonym for 'quit' in yaz-client
2346 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2347 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2348 for the new members. Patch by Ko van der Sloot.
2350 Added support for SRU POST. It is supported for content-type
2351 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2353 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2354 Instead make the library libyaz.la multi-threaded. Threading as a whole
2355 can still be disabled by configure option --disable-threads. Previosly,
2356 with older GLIBCs there were problems with MT libs under Apache. This
2357 has now been fixed a long time ago.
2359 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2362 CQL module modified to be case insensitive for relations/indexes/operations.
2364 Fixed bug in CQL transform code: incorrect value relationModifieder
2367 Added 'show all' command for yaz-client which retrieves all results
2370 Added new yaz-client, xmles, which takes a (private) OID and
2371 a document to be sent as an extended service request.
2373 Describe new yaz-client commands wait_response and set_auto_wait.
2375 Increase TCP/IP listener backlog from 3 (which I am guessing was
2376 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2377 that the socket will queue as many incoming connections as it's able
2378 to handle ongoing connections. In other words, it will never now
2379 refuse a connection that it would be able to handle merely because
2380 it's not got around to accepting() enough of the pending connections
2381 yet. This is the behaviour anyway under Linux, where the listen()
2382 argument is ignored; but not under BSD and on systems such as
2383 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2384 YAZ-based servers should now be uniform across operating systems in
2387 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2388 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2389 This allows yaz-marcdump to read large MARC batches (>2 GB).
2391 Modified all YAZ source files - except the source which is auto-generated
2392 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2395 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2396 corresponding to the existing *_setl() function. These allow option
2397 values containing arbitrary valuues.
2399 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2400 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2401 except that it returns an indicator of whether or not the sort
2402 criterion was accepted (0 for OK, -1 for invalid).
2404 --- 2.1.8 2005/06/07
2406 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2407 MARC output rather than returning "new" buffer.
2409 yaz-client warns about unknown init options.
2411 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2413 --- 2.1.6 2005/05/24
2415 Added support for SRW sort in Generic Frontend Server. Patch
2416 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2417 sortKeys - or NULL if none is provided.
2419 Fixed bug #307: It was impossible to specify indefinite/no timeout
2420 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2423 Added support for multiple languages and charsets to be specified in
2424 ZOOM. Each charset/language is separated by a blank. If negotiation is
2425 in effect in init-response, Option
2426 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2427 Code based on patch by Vasiliy Osadchuk.
2429 Fixed bug #306: infinite recursion that occurred when calling
2430 yaz_log_level_init as the first call (before other log level or
2433 Fixed bug in scan handling in front end server: if preferred-Position-In-
2434 Response was non-present, a NULL pointer referece was performed.
2436 --- 2.1.4 2005/04/26
2438 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2439 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2440 now defined for all those error codes. So instead of putting 109 in
2441 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2442 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2444 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2447 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2449 Program yaz-client now exits and produces an error message if multiple
2450 Z39.50 servers are specified on the command line (none or one allowed
2453 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2456 --- 2.1.2 2005/03/16
2458 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2460 Fixed bug #272: Preserve spacing for CCL terms.
2462 --- 2.1.0 2005/03/14
2464 Added support for virtual hosts and multiple backend servers for
2465 the YAZ frontend server. The configution is XML based and
2466 support specificition of CQL to RPN mappings and explain information.
2467 See section "Virtual Hosts" in the YAZ manual.
2469 Extended OPAC display utility. OPAC display utility renders
2470 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2471 to supplement yaz_marc_decode_wrbuf.
2473 Fixed a bug in MARC decoder that could caused it to crash for some
2474 invalid MARC records. More diagnostics and warnings where added in
2475 XML output (warnings, etc are stored in comments).
2477 --- 2.0.34 2005/02/08
2479 Fixes for UNIX domain sockets. Bug #261.
2481 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2483 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2484 Added yaz_marc_subfield_str which defines subfield lead string which is
2485 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2486 yaz_marc_endline_str which defines end of fields string used in
2487 YAZ_MARC_LINE format. Default string is newline.
2489 Experimental support for MarcXChange. This format can be produced
2490 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2491 http://www.bs.dk/standards/MarcXchange.xsd
2493 Added yaz-client commands scansize that sets maximum number of
2494 entries to be returned by scan.
2496 --- 2.0.32 2005/01/11
2498 Added support for SRW scan in yaz-client and Generic Frontend Server.
2500 * Added whereInList member to SRW Scan Term.
2502 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2504 Fixed NMEM system to return aligned blocks on the smallest boundaries
2505 that are suitably aligned for all possible types on the particular
2506 architecture YAZ is being built for.
2508 --- 2.0.30 2005/01/04
2510 Fixed numerious warnings that was issued with newer versions of GCC.
2512 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2513 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2516 Make YAZ Generic Frontend Server slightly faster.
2518 Enhance (and reduce) logging for Generic Frontend Server.
2520 Revert YAZ log system so that it flushes every write operation
2521 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2523 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2524 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2525 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2526 will effectively disable old definitions.
2528 --- 2.0.28 2004/11/09
2530 Added yaz_log_time_format which specifies log format using
2533 Added yaz_log_module_level which returns mask for a module. Value
2534 is non-zero mask a if module is enabled; zero if disabled.
2536 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2537 in include/yaz/cql.h.
2539 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2541 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2543 Fixed bug #172: RPM builds does not enable SSL.
2545 Doxyfile.in part of dist. Doxyfile generated by configure.
2547 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2548 are given and the corresponding component does not exist.
2550 Extend CCL documentation in YAZ reference. Describe r=r.
2552 --- 2.0.26 2004/10/01
2554 Fixed MARC->MARCXML conversion to properly deal with
2555 fields, subfields, indicators having non-ASCII characters.
2557 Fixed MARC->MARCXML conversion so that ASCII control characters
2558 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2561 Added YAZ GFS support for conversion from Z39.50 surrogate
2562 diagnostics to SRW surrogate diagnostics.
2564 Bug fix: YAZ GFS did not return schema in explainResponse.
2566 --- 2.0.25 2004/09/30
2568 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2569 now converts recordSchema to elementSetName as well as schema URI.
2571 Fixed bug in COMSTACK that prevented HTTP request packages from being
2574 --- 2.0.24 2004/09/29
2576 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2577 does not require white-space before and after the dash in a range, e.g.
2578 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2581 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2582 due to new GCC removing "redundant" code.
2584 Added yaz-client commands scanpos and scanstep that sets preferred
2585 position and step-size for scan.
2587 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2589 Added CCL utility ccl_qual_buf which parses one or more CCL
2590 spec lines in a buffer.
2592 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2593 of name and value - ignoring empty lines and comments.
2595 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2597 Added odr_get_element_path which returns current element path for an
2598 ODR handle. This utility is useful in error handling or user-defined
2601 Added ODR_PRINT utility odr_set_stream which is is a more generic
2602 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2603 to a write function and pointer to close function. The close function - if
2604 non-NULL - will be called during odr_destroy.
2606 Fixed bug in CCL parser where truncation char was not removed from
2607 right side when truncation=both was in effect.
2609 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2612 --- 2.0.23 2004/08/11
2614 Fix buffer overrun in CQL parser when dealing with proximity (%).
2616 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2617 to UTF-8/UCS conversion is now only based on codetables.xml.
2619 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2621 --- 2.0.22 2004/08/06
2623 Add support for more "commit changes" in ZOOM (uses Extended Services).
2625 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2628 Yet another small fix for configure of SSL.
2630 --- 2.0.21 2004/05/14
2632 Fix SSL libs for configure when --with-openssl=DIR is given.
2634 --- 2.0.20 2004/05/10
2636 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2638 SSL comstack now uses yaz.pem certificate file on server side
2639 by default. Certificate filename can be configured by calling
2640 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2642 Fix bug regarding multiple calls to ZOOM_connection_connect.
2644 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2646 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2647 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2649 ZOOM now allows inspection of X509 peer certificate for verification.
2650 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2652 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2653 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2654 as "modular" but it simplifies things.
2656 Added cs_get_peer_certificate to that returns peer X509 PEM.
2658 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2659 NULL if SSL is unavailable.
2661 Documentation about MARC decoding tools.
2663 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2665 --- 2.0.19 2004/03/30
2667 Rename CHANGELOG to NEWS to follow GNU style packing.
2669 Fix bug with missing initialization of member in init_diagnostics.
2670 This bug affects threaded version of GFS server.
2672 --- 2.0.18 2004/03/20
2674 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2677 Ensure zlib.dll is packed with Windows install.
2679 --- 2.0.17 2004/03/17
2681 Fix encoding of xsd:string to use text instead of CDATA.
2683 Fix endless loop in CQL parser with unbalanced ".
2685 Use a more compact way to store MARC-8 conversion tables.
2687 --- 2.0.16 2004/03/16 Debian only
2689 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2692 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2697 --- 2.0.15 2004/03/01
2699 Another fix for decoding of XML packed records.
2701 --- 2.0.14 2004/02/25
2703 Fixes for Chunked encoding. White space not ignored after length spec.
2705 Update NS and use default NS for SRW diagnostic elements.
2707 --- 2.0.13 2004/02/23
2709 Implement ZOOM_resultset_cache_reset which resets record cache.
2711 Implement ZOOM_resultset_sort which sorts a result set.
2713 Implement chunked HTTP transfer.
2715 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2717 --- 2.0.12 2004/02/16
2719 Added member 'schema' to bend_explain_rr structure so that backend
2720 can specify explain record identifier. Defaults to Zeerex 2.0.
2722 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2724 --- 2.0.11 2004/02/16
2726 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2729 Added init command for yaz-client which sends "extra" init request.
2731 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2732 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2734 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2736 Make ZOOM error code for "invalid query".
2738 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2740 --- 2.0.10 2004/02/05
2742 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2745 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2747 Added option -p <file> to make Generic Frontend Server to write PID file.
2749 Added option -D to put Generic Frontend Server in background on its own.
2751 Make ZOOM C recognize option "password". If unset, "pass" is used
2752 (for backwards compatibility).
2754 Fixed a bug in Generic Frontend Server that could make it crash if a
2755 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2758 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2759 Must be issued before open, in order to be in effect.
2761 --- 2.0.9-6 2004/01/12 Debian/Windows
2763 Make the SRU server more picky WRT unknown params, etc.
2765 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2767 New YAZ client command, options, that sets Z39.50 options.
2769 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2770 options from a string of tokens (one token for each option bit).
2772 Update SRW diagnostic code messages.
2774 --- 2.0.9-5 2004/01/07 Debian/Windows
2776 Handle user defined stylesheet for SRW/SRU.
2778 --- 2.0.9-4 2004/01/06 Debian/Windows
2780 Fix bug in decoding of Content-Length.
2782 --- 2.0.9-3 2004/01/06 Debian/Windows
2784 Fix a bug with decoding of XML packed records.
2786 --- 2.0.9-2 2004/01/05 Debian only
2788 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2790 Fix bug in SRW/SRU diagnostics decoding.
2792 --- 2.0.9 2004/01/05
2794 Fixed bug in Generic Frontend Server which could drop records exceeding
2795 preferred message size. Reported and fixed by Irina Dijour.
2797 Fixed calculation of package size for structured records in Generic
2798 Frontend Server. Reported and fixed by Irina Dijour.
2800 Fixed namespace for SRW/SRU diagnostics.
2802 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2804 --- 2.0.8 2003/12/22
2806 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2807 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2810 CQL changes to reflect recent changes to the specification:
2811 * Documentation talks about context sets instead of index sets.
2812 * Documentation talks about indexes instead of qualifiers.
2813 * The CQL-to-PQF transformer's configuration file now uses
2814 "index.set.name = <attributes>" instead of the old form
2815 "qualifier.set.name = <attributes>". (Both forms are still
2816 understood but the latter is deprecated.)
2817 * CQL terms with no explicit index specified are now interpreted as
2818 cql.serverChoice instead of srw.serverChoice (which of course
2819 behaves exactly the same.)
2821 --- 2.0.7 2003/12/16
2823 MARC conversion can now generate ISO2709 output in another
2824 character set. yaz-marcdump uses this facility if you invoke it
2827 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2828 functions from there can be used from C++.
2830 --- 2.0.6 2003/12/04
2832 Frontend server now transfers memory from decoded packages to stream
2835 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2836 references to show up.
2838 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2839 the ZOOM Abstract API. The older names for the same options are still
2840 also supported for the benefit of old applications.
2842 ZOOM-C supports "implementationId" and "implementationVersion" options
2843 to go along with "implementationName". These allow the user code to
2844 specify identification strings to be sent to servers.
2845 Add OID for the new ExtLite attribute set.
2847 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2848 as requested/supplid by Ere Maijala <ere@atp.fi>
2850 For generic frontend server, reverse the order of
2851 "toolkit-supplied / application-supplied" strings sent as implementationId,
2852 Name and Version. Also, remove the spaces around the slash. This brings
2853 the GFS in line with the behaviour of ZOOM-C on the client side.
2855 Add function ZOOM_scanset_display_term.
2857 yaz-client shows scan displayTerm if present.
2859 Utility yaz-iconv is now installed by default along with the man page
2862 Extend configure check for OpenSSL to use pkg-config where available (such
2865 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2866 server to specify uid/gid/mask for socket using the format
2867 unix:[user=uid,][group=gid,][umask=mask,]file=path
2868 If file= is omitted the existing format is assumed, e.g.
2870 in which case the mask is 0666 (rw for everybody).
2872 Major restructure of YAZ source. All source in libyaz is in src directory.
2873 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2874 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2876 Added man page for utility yaz-marcdump (used to be called marcdump).
2877 yaz-marcdump is installed by 'make install'.
2879 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2880 of incoming package failed.
2882 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2884 Change prototype of odr_perror: add const to message string.
2886 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2888 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2889 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2890 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2891 DNS lookup. There should not be any compatibility problems with this
2892 assuming that blocking=1 or 0 is used.
2894 Fix bad reference in UNIX comstack in function cs_addrstr.
2896 Fix for compilation on AIX.
2898 The generic front-end server (server/seshigh.c) now supports returning
2899 Init diagnostics to the client in User-information-field, in
2900 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2903 --- 2.0.4 2003/09/04
2905 Allow any CQL relation (not just all,any,exact,scr).
2907 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2908 that features the same UI.
2910 Implemented command update0 in YAZ client which is equivalent to
2911 update but uses old of Ext Update ASN.1.
2913 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2914 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2915 Previously no OID was used for this info.
2917 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2918 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2919 returns 'malformed search term' otherwise.
2921 SortResponse member resultCount now set to NULL in sort handler of
2924 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2927 Add three new utility functions for translating OIDs between various
2928 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2929 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2930 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2931 char *oid_to_dotstring(const int *oid, char *oidbuf);
2932 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2934 Reverted modifications for ES Update definition for z_IU0Update
2935 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2936 is back to YAZ 2.0.2.
2938 String value attributes for CCL parser.
2940 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2941 which their FirstSearch server returns in Init responses, sometimes
2942 carrying useful diagnostic information when Init fails. This has the
2943 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2944 "z39.50/oclcui.asn", where its definition is somewhat different from
2945 what OCLC document on their web-site, as required to interoperate with
2948 Support for anonymous authentication in yaz-client. Use the command
2951 * Fix the OID of the Index Data-local "admin" Extended Service from
2952 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2953 the 1000, which indicates a locally-defined OID, was a mistake.
2955 --- 2.0.3 2003/06/20
2957 Fix CCL directive @case handling so that it affects string match for
2958 both CCL keywords and qualifiers.
2960 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2961 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2962 Decoder has been updated with ASN.1 changes as listed in
2963 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2964 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2965 z_IUUpdate, remains unchanged.
2967 ZOOM_record_get may now return a record in a specific character set.
2968 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2969 "from" is the character set of record as returned by target. "to" is
2970 the character set to be returned. If omitted, "to" is UTF-8.
2972 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2974 New ODR utility, odr_getelement, which returns name of element for
2975 which encoding/decoding failed.
2977 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2978 in cases where a required element was omitted.
2980 Bug fix: some MARC8 sequences were not converted.
2982 New ZOOM option "step" which specifies number of records to be
2983 retrieved in one chunk. Used in conjunction with "start" and "count".
2985 SRW support for yaz-client. Use scheme http: to use it, e.g.
2988 yaz-client no longer does (un)intelligent character set conversions
2989 by default. Can be enabled with charset and marc_charset commands.
2991 xmalloc trace fix for 64-bit systems such as DEC alpha.
2993 Solaris 2.6 compile fix.
2995 New function, cql_strerror() translates SRW error codes, as returned
2996 by cql_transform_error(), into human-readable English strings. Used
2997 in yaz-client diagnostics when appropriate.
2999 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3000 converts it into a type-1 query which is sent to the server. This
3001 makes CQL available for use with all Z-servers, as opposed to the tiny
3002 minority that can handle CQL queries themselves.
3004 --- 2.0.2 2003/04/28
3006 New Debian package layout similar to the Redhat Package layout.
3008 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3009 and search result respectively.
3011 --- 2.0.1 2003/04/25
3013 Redhat package is now several packages: libyaz (runtime libraries),
3014 libyaz-devel (development and documentation, and yaz (utility programs).
3015 Package spec file by Morten Bogeskov.
3017 New member 'schema' in struct bend_fetch_rr which the name of requested
3018 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3019 handler MAY set this to reflect the schema of the returned record.
3021 New member 'display_term' in struct scan_entry. GFS now sets member entries
3022 and allocates scan entries to be filled by user scan handler. In previous
3023 version, entries member was allocated by the scan handler. That still works,
3024 but the GFS will ignore member display_term - assuming it was NOT set by
3025 the handler. The fact that the GFS now allocates the entries both allows
3026 for new members and makes a scan handler easier to write.
3028 Fix CQL lex buffer overflow.
3030 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3031 SRU default recordPacking is string.
3033 SRU protocol support for frontend server.
3035 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3037 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3039 Added scan for the ZOOM shell (zoomsh).
3043 * String Identifers for Schemas (Amendment 5).
3044 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3045 Old definition for schema
3046 Odr_oid *schema; /* OPT */
3051 Z_InternationalString *uri;
3052 #define Z_Schema_oid 1
3053 #define Z_Schema_uri 2
3056 * resultCount parameter to Sort Response (Amendment 1).
3057 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3059 Support for SRW 1.0 over HTTP. This is an optional feature and
3060 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3063 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3064 on the same port. SRW SearchRetrieveRequests are mapped
3065 to bend_init,bend_search,bend_fetch,bend_close.
3067 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3069 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3070 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3072 ZOOM connections are SRW based if schem http is used for hostname
3073 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3074 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3076 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3077 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3078 distance=n, order=true/false, relation=le, prox unit=word. If
3079 n is omitted, distance 1 is used.
3081 Fixed problem with C compiler include path in wrong order.
3083 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3084 on Solaris. Patch from Ko van der Sloot.
3086 New MARC decode API. All new functions operate on a yaz_marc_t
3087 handle. The most important new functions are: yaz_marc_create,
3088 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3089 decode and destroy respectively. Decoder can produce formats
3090 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3091 include/yaz/marcdisp.h.
3093 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3094 to UTF-8, UCS-32, wchar_t or Latin-1.
3096 * Prototypes for yaz_iconv_-functions moved to separate header
3097 include/yaz/yaz-iconv.h.
3099 Make a few private functions 'static' in unix.c. This prevents
3100 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3102 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3103 are set when Init Response is received.
3105 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3106 but returns diagnostic set as well.
3108 New function yaz_strerror which is a portable wrapper for
3109 strerror/strerror_r/GetLastMessage.
3111 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3112 is returned for MARC. If type is "oai", then OAI MARC is returned.
3114 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3117 --- 1.9.2 2002/11/26
3119 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3121 Fix bad race conditions on SIGTERM and terminate gracefully in
3124 Move retrieval (data1) module to Zebra since nobody seems to be
3127 Add GRS-1 render for ZOOM using same format as yaz-client.
3129 --- 1.9.1 2002/10/05
3131 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3133 Fix broken ESpec handling in data1 module.
3135 SGML reader parses comments and makes them part of the data1 tree.
3137 Added several type casts so that YAZ compiles as C++ code.
3139 ZOOM didn't handle PDU encoding failures properly.
3141 Added more Bib-1 diagnostics (approved extensions).
3143 GNU configure: better check for iconv.
3145 More portable use of accept, getpeername. Check for socklen_t. Use
3146 int/size_t if socklen_t is not defined.
3150 PQF parser rejects bad queries - including those with extra
3151 characters in them. PQF parser used to silently ignore that.
3152 Cleaner API for PQF added, which allows you to get detailed
3153 error information for bad queries (see yaz/pquery.h).
3155 Fixed bug in ZOOM_record_get for type "database".
3157 Implemented mini iconv library supporting conversions between
3158 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3160 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3162 --- 1.8.9 2002/08/20
3164 Fixed ZOOM C record cache so that preferredRecordSyntax and
3165 elementSetName is used to check for already fetched records.
3167 --- 1.8.8 2002/08/02
3169 Added three members in bend_initrequest structure to facilitate
3170 character set negotiation.
3172 Fixed a bug in frontend server that could cause indefinite
3173 loops under rare conditions.
3175 Revised character set utilities (charneg.h) so that encoding
3176 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3178 For PQF, directive @term <type> sets term type for Scan/Search.
3179 Here <type> is general, string, numeric, null. The term type
3180 is inherited - just like @attr.
3182 New call odr_set_charset that sets character set conversion for
3183 international-strings on a ODR stream. Prototype is:
3184 int odr_set_charset(ODR o, const char *to, const char *from);
3185 The InternationalString is still represented as C string in YAZ
3186 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3187 won't). On the protocol level, you can use any encoding.
3189 Support for UNIX sockets in ZOOM.
3191 Solaris recv sometimes returns errno == ENOENT. It is treated as
3192 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3194 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3195 both client and server. Code by Morten Bogeskov.
3197 --- 1.8.7 2002/05/22
3199 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3200 that they can be used directly from Visual Basic. You must recompile
3201 your windows APP if you're using ZOOM.
3203 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3204 Commands "lang" and "charset" sets language and character set respectively.
3205 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3206 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3208 Attributes from multiple CCL fields may be OR'ed rather than merged
3209 using directive "@field or". Fields are still merged by default -
3210 equivalent to "@field merge".
3212 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3215 Fixed bug in zget for parameter ExtendedServicesResponse.
3219 --- 1.8.6 2002/03/25
3221 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3223 Client displays USR.1:SearchResult-1 (hits per term).
3225 Additional Search Info for search in Generic Frontend Server.
3227 Fixed CCL parsing of "field=s".
3229 WIN32 installer - using the excellent NSIS software from nullsoft.
3231 Fixed CCL parsing of "field = - <number>".
3233 Added function yaz_marc_decode that decodes MARC for line mode
3234 display or XML (similar to that used by JZKit).
3236 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3237 Z39.50. But ISO/ILL was, however.
3239 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3240 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3242 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3243 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3245 --- 1.8.5 2002/02/03
3247 New YAZ client features: Command completion and new commands:
3248 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3249 Code provided by Jacob Poulsen.
3251 New call oid_trav, that visits all registered OIDs via callback.
3253 Function ZOOM_record_get now returns const char pointer rather than
3254 void pointer. It saves a lot of type casts.
3256 For YAZ client, command "auth" now allows you to set authentication
3257 in IdPass style. It is enabled when three tokens are given - order
3258 is user, group and password.
3260 Fix memory leaks in MARC record handling for ZOOM.
3262 New option for YAZ client, -k <kilobytes> that sets
3263 maximum record size. Similar to -k option for generic frontend
3264 server and yaz-ztest.
3266 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3268 Prefix query parser reports "fail" when bad attribute set is given.
3270 Fix in MARC decoder. Proximity logging. Fix for attribute set
3271 in scan handler for server. Patches by Shigeru Ishida.
3273 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3276 Configure option --with-openssl=<dir> now works when a directory is
3277 specified. Patch provided by Morten Bogeskov.
3279 New option for YAZ client, -u <auth>, that sets authentication.
3281 ZOOM fix: error information was sometimes "missing", since error
3282 was cleared/reset too when it shouldn't.
3284 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3286 --- 1.8.4 2002/01/04
3288 Scan for ZOOM API. New object ZOOM_scanset. New functions
3289 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3290 ZOOM_scanset_destroy.
3292 New ZOOM function, ZOOM_connection_last_event, that returns type
3293 of last event (such as "receive data", "send data", "apdu received",
3296 New ZOOM option, schema, that specifies schema for retrieval.
3298 New CCL feature. Qualifiers can be aliases for one or more
3299 other qualifiers (if more than one is given, OR is used).
3301 ZOOM uses named result sets if target supports it.
3303 Two new YAZ client commands: . (dot, which sources a script of YAZ
3304 client commands), and ! (to execute shell command.). Implemented
3307 Working on Debian packages.
3309 --- 1.8.3 2001/11/19
3311 YAZ client enables named result sets only if target supports it.
3313 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3315 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3316 with key="host" to get same result.
3318 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3319 Function Z3950_resultset_record(s) returns references to records
3320 "owned" by resultset. To become owner use Z3950_record_clone.
3322 Function z_ext_record handles Extended Services. Thanks to
3325 --- 1.8.2 2001/11/12
3327 CCL Parser fix: ignore token comma when dealing with and-lists.
3329 Documentation updates for COMSTACK.
3331 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3332 Changed prototype Z3950_records. For some functions, int parameters
3333 were changed to size_t.
3335 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3338 New MARC decode/display function, marc_display_exl, which properly rejects
3339 non-ISO2709 records. YAZ client uses it.
3341 --- 1.8.1 2001/10/29
3343 Fix bug: local attribute set wasn't set correctly in PQF strings.
3347 * Old Z39.50 codecs no longer supported.
3349 Added ZOOM C binding. See http://zoom.z3950.org/
3351 Renamed states for COMSTACKs to avoid confusion with events.
3353 Implemented cs_look and proper cs_rcvconnect.
3355 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3357 Configure detects POSIX threads on OpenBSD.
3359 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3360 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3362 When error is returned from present handler, non-surrogate diagnostic
3363 is returned in present response (and fetch handler is no longer called).
3365 * Minor adjustments to pquery parser (PQF). Token characters may be
3366 escaped by using backslash (C-style).
3368 PQF parser allows string attribute values to be specified. For @attr,
3369 non-numeric characters after the equal-sign are treated as strings
3370 (e.g. @attr 9=title).
3372 CCL trunction character may be defined (@truncation in file)
3374 * function zget_ExtendedServicesRequest sets waitAction to
3375 waitIfPossible (was wait).
3377 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3380 CCL operator names may be set in field definition files (CCL_bibset).
3381 See ccl/bib1 for an example.
3383 Fixes in ASN.1 compiler for C++ compatibility.
3385 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3386 and "op_or" to avoid conflict with C++.
3388 Fixed problem with GNU readline detection on Redhat 7.0.
3390 Added step-size for Scan backend handler.
3392 Fixed bug that made the frontend server crash when no attribute
3393 set was specified for scan.
3395 Front-end server automatically switches to original working directory
3396 when installed as an NT service. Previously -w had to be specified to
3399 Added extended attributes for retrieval module (data1), so that data1
3400 records carry d1_readXML/SGML attributes. d1_read also supports
3401 null-data rules ( <tag/>)
3403 On UNIX when POSIX threads are available, a separate library libyazthread
3404 is created. Programmers should link with that library and the yaz library
3405 when using threads. The reason for the split was that some applications
3406 on Linux, such as Apache, doesn't work well when using shared objects that
3409 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3410 (or any frontend server) in SSL mode by specifying ssl: followed by
3411 address. Only tested on UNIX.
3413 Added feature for CCL module. Virtual structure s=al or s=ol generates
3414 and-list and or-list respectively instead of phrase search.
3418 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3419 log_mask_str. This was done to avoid name conflicts with other libraries
3420 (such as other PHP extensions).
3422 Added raw OID member for preferred record syntax (request_format_raw)
3423 and returned record syntax (output_format_raw) for backend fetch method.
3425 Config file yaz-config now accepts options so that it returns specific
3426 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3428 Shared library support for UNIX using GNU libtool.
3430 * Modified backend interface. Request/Response struct's replaced by
3431 one read/write C struct. For example bend_fetchrequest and
3432 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3433 Every handler - even search has to be registered in bend_init
3434 handler. This means that the YAZ library no longer refers to
3435 external functions and it makes it possible to make the whole
3436 thing a single DLL/SO.
3438 Added Segment handler for backend server.
3440 Added Zmbol/Zebra administrative functions to YAZ client.
3442 Threaded frontend server on UNIX (when POSIX Threads are available).
3443 Starting the server with option -T enables multi-threading.
3447 Added configure option --enable-comp/disable-comp to control use
3448 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3449 located in sub directory asn.
3451 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3452 in ${exec_prefix}/bin along with the other programs yaz-client and
3455 GNU automake used to maintain makefiles.
3457 Added several OID's.
3459 Changed retrieval module so that we can load records with no abstract
3460 syntax defined. Tagpaths in these records are fully composed of string
3463 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3467 On UNIX, the generated makefile now supports a proper 'make install'.
3468 The prefix can be set via GNU configure to set the install location
3469 (default is /usr/local).
3471 * YAZ programs client and ztest were renamed to yaz-client and
3472 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3473 locations, such as /usr/bin,/usr/local/bin,etc.
3475 * YAZ Header files were moved from include to include/yaz. YAZ Header
3476 files are referred to as include <yaz/log.h> rather than <log.h>.
3477 The YAZ include path (-I ..) is therefore the same as before. Programmers
3478 should update their #include statements or use -Ipath/include/yaz
3479 instead. The main motivation for doing this change is that YAZ header files
3480 can be installed in "standard" locations /usr/include,/usr/local/include
3481 without introducing conflicts, since ALL YAZ header files are stored
3482 in subdirectory yaz (under /usr/include for example).
3484 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3485 rather than project/workspace files. We switched because project files
3486 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3489 Changed name of logging function, logf, to yaz_log, to prevent name
3490 clash with some math-log functions. The YAZ header log.h defines logf
3491 to yaz_log (#define) so there should be no incompatibilities by this
3494 Added bend_start/bend_stop handlers for server. These handler are
3495 called on start/stop of server. For windows they are called whenever
3496 a service is started/stopped.
3498 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3499 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3500 in util/yc.tcl. The auto-generated C code structures are, in a few
3501 cases, incompatible with the old decoders. There are differences in the
3502 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3503 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3504 The preprocessor variable ASN_COMPILED is defined when the compiled
3505 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3506 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3507 wish to use the old encoders/decoders you can specify --disable-yc
3510 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3511 version so that it supports both new - and old version of DB Update
3513 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3514 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3515 change. The name parameter can be set to 0 in which no name is specified
3516 for the construction. The macros odr_implicit and odr_explicit sets name
3517 parameter to zero for the construction involved. New macros
3518 odr_implicit_tag and odr_explicit_tag are similar to the others,
3519 except that a name parameter is added. For programmers' that don't use
3520 ODR they probably only need to change the call to z_APDU and z_External.
3522 Added access control facility by interfacing the TCP wrapper library.
3523 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3524 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3525 name of the daemon and enables the access control as specified in
3526 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3528 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3529 den Dool <H.M.vdnDool@kub.nl>.
3531 Added reference ID parameter to most functions in server API - refer
3532 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3534 Changed name of ccl library to libccl.a (was ccl.a).
3536 Fixed bug in decoder for Explain (Category TargetInfo).
3538 Added support for GNU readline in client. Thanks to Jacob Poulsen
3539 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3541 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3542 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3543 IMPLEMENTATION! This change was made to the development version before
3544 the ZIG decided to retract the amendment. If any users MUST be
3545 compatible with the original Update definition, PLEASE CONTACT US, and
3546 we will include a separate definition corresponding to the old Update
3547 ES. Note that because of the change to the ASN.1 of the
3548 TaskPackageRecordStructure we cannot define a single structure that
3549 will support both versions.
3551 * Added const modifier to buffer parameter for some ODR/BER encoding
3552 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3553 completeWAIS, odr_dumpBER.
3555 Fixed bug in client.c which caused a crash when a scanResponse didn't
3556 contain positionOfTerm.
3558 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3559 * will cause an error in a client if a non-YAZ target sends both a
3560 * list of Scan entries and non-surrogate diagnostics.
3562 Retrieval module enhancements. Tag sets may be typed in the reference
3563 to it. From the .abs-file the "tagset" directive takes a third optional
3564 integer type for the tag set referenced. From a .tag-file the "include"
3565 directive takes a third optional type as well. The old "type" directive
3566 in the tag set itself is still recognized but acts as the default type
3569 Backend interface change. Individual Scan terms returned from bend_scan
3570 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3571 in include/backend.h.
3573 Retrieval module enhancements. Multiple tag sets and attribute sets may
3574 be specified in abstract syntax specs. Revised the error/warning for
3575 logging messages reported by the retrieval module when reading the
3578 Object Identifier system (oid_..) changed. The API is backwards
3579 compatible but the oid-routines now allocates new OID's when needed.
3580 Raw OID's may be specified in oid_getvalbyname.
3582 YAZ now uses GNU configure to generate Makefile(s).
3584 * Minor changes in some of the member names of DeleteResultSetRequest and
3585 DeleteResultSetResponse. See include/proto.h.
3587 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3588 and added member 'languages' in TargetInfo (which was missing).
3590 Changed the way attribute sets are handled in the retrieval
3591 module. These are now cached, just like the abstract syntaxes
3594 Changed YAZ so that it links with compiled ASN.1.
3596 Added Explain-schema definitions and mapping routines. The following
3597 Explain categories have been implemented: AttributeDetails,
3598 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3600 Fixed minor bug in Windows version of Server Library.
3602 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3604 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3606 Added EXTERNAL: UNIverse Resource Report (non-standard).
3608 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3609 ENUMERATED and SET OF.
3611 * Added 'const' to some of the char pointer arguments for the
3612 functions, data1_read_node, data1_getelementbytagname,
3613 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3616 Fixed bug in data1_insert_taggeddata - the last_child member of
3617 parent wasn't initialised.
3619 * Changed data1_read_record and data1_read_node so that the supplied
3620 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3621 doesn't refer to any parts of the "SGML"-buffer.
3623 Fixed bug in server library (Windows version of statserv_remove).
3625 * Changed code so that it compiles as C++. The type definition
3626 of Odr_fun which is a member of Odr_arm was changed. The result is,
3627 that an explicit typecast is needed for the fun pointer when
3628 using Odr_arm - as in:
3629 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3631 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3633 Implemented the new structured date and time definition as approved
3634 by the ZIG. Added schemaId element to the specificTag in Espec-1
3635 (also approved at the last ZIG). Thanks to RVDM.
3637 Added some Object identifiers (RVDM).
3639 Changed the Update Extended Service (RVDM).
3641 Added command "refid" to client which specifies referenceId for
3642 the following requests.
3644 Implemented extended service handling for server. See ztest.c
3645 for an example as well as backend.h. New handlers are registerd
3646 in the Init handler.
3648 * Changed interface for sort in server.
3650 Added new members to statserv_options_block. It allows a server
3651 to read options from another source than just the command line. Thanks
3652 to Charles Woodfield.
3654 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3655 renamed to zboolean. Some C++ compilers complained about the name.
3657 Minor changes to gils.abs. Added index 's' (sort) on title
3658 and date/time-last-modified.
3660 --- 1.4pl2 1998/1/30
3662 Fixed bug in server library regarding inetd mode (-i). This bug
3663 was introduced by release 1.4.
3665 --- 1.4pl1 1998/1/29
3667 Added sort facility in client and backend server interface.
3669 Fixed problem with dependencies in Makefile(s).
3671 Fixed bugs for encoders/decoders of extended services and
3674 Implemented sub-tree feature for schemas. Sub-trees are
3675 referenced in *.abs-files. See explain.abs for an example
3676 of the use of this feature.
3678 Modified bib1.att; local attributes for ANY didn't include
3679 ANY itself (only affects use of the retrieval module).
3681 Fixed bug in plain SGML reader in function data1_read_node:
3682 tags with prefix "var" was incorrectly interpreted as variants.
3684 Added feature "sub-schemas" to enable references to - and definitions
3685 of - group of elements.
3687 * Removed member parent from type data1_element (in data1.h).
3689 Implemented function odr_nullval() that returns the value of
3692 * Removed member num_children from data1_node (in data1.h).
3694 Made NT service interface part of the server library. The
3695 function statserv_main uses the NT service when required and
3696 calls the statserv_start / statserv_close routines.
3698 Routine zget_SearchRequest and zget_PresentRequest fills
3699 resultSetName/Id member with "default" instead of "Default".
3701 Fixed memory leak in server. Request queue member wasn't freed.
3703 Fixed nmem_exit so that memory is freed.
3707 Revised the CCL parser utility to be thread safe.
3709 Added function, oid_ent_to_oid, to replace the function
3710 oid_getoidbyent, which is not thread safe.
3712 * Added nmem_init and nmem_exit to initialize and release
3713 NMEM resources. Function nmem_init should be called once in the
3714 initial thread before NMEM/ODR is used. statserv.c and client.c
3715 have been changed accordingly. The change was necessary to make
3716 NMEM thread safe. The NMEM memory pool is shared amongst threads
3717 in a process. Unix-based applications will still work fine without
3720 Added NT Services interface for the the Z39.50 (statserv) Server.
3721 Refer to the ztest.c source on the usage.
3723 Windows 95/NT port using MSVC5.0. Project files are included in the
3726 * Defined new 'global' handle for the retrieval (data1) system. The
3727 new handled, data1_handle, describes the state of the data1 system.
3728 This handle is passed as first argument to virtually all
3729 data1 related routines. The functions data1_create and data1_destroy
3730 creates and destroys a data1 handle respectively.
3732 Added ODR encode stream member to all backend request structures
3733 init, search, scan etc. This stream should be used to allocate all
3734 memory used for the response when thread safe operation is needed.
3736 Changed the comstack utility, cs_addstr, to be thread safe. The
3737 returned hostname string returned by the function is now part the
3740 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3741 function. The cs_straddr takes a COMSTACK handle as argument, so this
3742 function must be used after cs_create and before bind/connect.
3743 This function is thread safe.
3745 Moved test server to 'ztest' directory - generic server code still
3746 in 'server' directory.
3748 Made prefix query (pquery.c) utility thread safe.
3750 Added new function modifier YAZ_EXPORT to 'export' public DLL
3751 functions when using windows (see include/yconfig.h).
3753 Added definitions to the OID database (util/oid.c) (RVDM).
3755 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3757 Added call to ccl_rpn_delete in client program.
3759 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3760 release of RPN structure.
3762 Added support for C++, headers uses extern "C" for public definitions.
3763 With input from RVDM.
3765 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3766 Thanks to Ronald van der Meer (RVDM).
3768 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3770 Added support for private extensions to the OID database
3771 (oid_setprivateoids()). Thanks to RVDM.
3773 Added optional, physical ANY (key replication)
3775 Fixed null-reference problem in GRS-1 output filter.
3777 Proximity operator added to Prefix Query Format (PQF).
3779 In test client command "base" accepts multiple databases.
3781 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3785 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3787 Smallish bug-fixes in the new encoders/decoders (explain).
3789 Bug fixed in DeleteRequest.
3791 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3793 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3795 Added SOIF syntax (using private OID for now) to retrieval module and client.
3797 Added Update extended service.
3799 Added SearchResult-1 additional info structure.
3801 Added optional CCL (ISO8777) interpreter as separate module. Available
3804 --- 1.2 1996/6/10 (1st anniversary release)
3806 Added Summary record syntax. Lightly tested.
3808 Added OPAC record syntax. Untested.
3810 Added ResourceReport service encoders/decoders. Untested.
3812 Fixed bug in z_Unit - wrong tagging on unitSystem.
3814 Fixed bug in the DiagRecs decoder.
3816 Added options for max PDU size and session timeout to frontend-server.
3818 Added documentation of query-language parsers and other supporting utilities.
3820 [frontend-server] Added Attribute set to the bend_scanrequest API.
3822 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3823 surrogate diagnostics were generated.
3825 [retrieval] Allow multiple local values for attribute.
3827 [retrieval] Allow multiple attributes per element in .abs files. index type.
3829 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3831 --- 1.1pl2 1996/4/10
3833 Minor changes, mostly specific to Zebra's requirements (retrieval)
3837 Repaired bug in frontend server when running multiple listening
3838 endpoints in dynamic mode.
3840 z_External() now won't break if a known, ASN.1 value comes encapsulated
3841 in an octet-string. The value will pass through unmodified in an Odr_oct.
3843 Added a bit of code to the demo client to decode & display
3844 ASN.1-structured records represented in the octet-aligned branch of
3845 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3847 Added z_ext_getentbyref() to the ASN module. Doc updated.
3849 * Completed the SCAN definition in the ASN module. This may break SCAN
3850 code based on older YAZ-versions at compile-time. The fix is easy -
3853 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3854 under the SCAN definition. Remember to initialize this, server-people.
3856 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3857 that this does not extend to ODR and ASN.
3859 Comstack allows insertion of established socket (primarily for
3860 inetd-operation of servers). Doc updated.
3862 Front-end server can now start from the inetd in TCP mode. Doc
3865 --- 1.0pl4 1996/1/24
3869 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3870 the rank and record number.
3872 Adjustments to the frontend server.
3874 Fixed diagnostic BER dumper. It ignored the file argument.
3878 Various changes to retrieval module.
3880 Changed the union discriminators of the protocol files from enums to
3881 ints paired with #defines.
3883 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3886 *Changed operator in the RPN structure to 'roperator', again to avoid a
3889 Fixed problems in Explain decoders/encoders.
3891 --- 1.0pl2 1995/12/6
3893 Memory bug in log module fixed.
3895 --- 1.0pl1 1995/12/5
3897 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3899 Bug in Explain DatabaseInfo module fixed.
3901 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3905 The shift to v1.0 signals that we now consider the *core* functionality
3906 of YAZ reasonably stable (the core being more or less equivalent to
3907 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3908 tested (Explain not at all - though that will happen soonish).
3910 Minor changes to code to support Windows port.
3912 Various minor changes after we're getting to use GRS-1 & co. more.
3914 Added Espec-1 format.
3916 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3917 of the protocol and it cannot be selected when encoding (maps into 'string'
3918 when decoding). Needed to talk to some servers.
3920 Demo client can request simple element set names.
3922 Added Diagnostic Format encoders/decoders.
3924 Added simple Close handling to frontend server (no hooks for resource
3925 reporting yet), and demonstration client.
3927 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3929 --- 1.0b3 1995/08/24
3931 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3932 handled incorrectly when records were requested in the searchResponse. This
3933 will only affect you if you use the frontend-server.
3935 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3936 Test-client will ask for and print GRS1. Ztest will return dummy records
3939 Added Explain encoders/decoders to the service-level API. Untested.
3941 Added Extended Services: Item Order encoders and decoders to the Service-
3942 level API. Untested. We could use a recent copy of the pertinent bits
3943 of the ILL protocol to add those bits.
3945 Added diagnostic format 1 encoders/decoders to the service-level API.
3948 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3949 odr_cons.c, which causes a more correct output.
3951 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3952 was always set to 0 when no records were requested in the searchRequest.
3954 * Added better external-handling. This shouldn't harm old code that
3955 *encodes* externals. It can break code that looks for a
3956 'single-ASN1-type' representation, since those types that are known
3957 are now decoded immediately. Look at the SUTRS sample code in
3958 seshigh.c and client.c. Documentation updated.
3960 Handling of structured records in bend_fetchresponse. Length -1 marks
3961 structured record, type is deduced from format field.
3963 --- 1.0b2 1995/06/27
3964 Fairly quick maintenance release to add SUTRS support.
3966 Fixed handling of SUTRS records in the demonstration client.
3968 * Added format field to the bend_fetchrequest and bend_fetchresponce
3969 structures of the backend API (frontend server). When the record is
3970 returned, the value of the format field is mapped to an OID. The
3971 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3972 of the record. The special value VAL_NONE in the bend_request means
3973 that no specific format was requested by the client. Documentation
3974 updated accordingly. Test server (ztest) will return a fixed dummy
3975 SUTRS record if your client requests SUTRS.
3977 Documentation updated accordingly.
3979 You can now set external libraries and RANLIB support in the top-level
3983 First public release.
