3 Make yaz_log_reopen async-signal YAZ-845
4 Fixes potential dead-lock issue with YAZ_DAEMON_LOG_REOPEN flags for
9 CCL: new feature s=spl (split-list) that splits terms in a search into
10 sub-phrases of all sizes (from 1 up to the number of terms) with order
11 preserved. For 3 terms the CCL search
14 @or @or @or @and @and a b c @and "a b" c @and a "b c" "a b c"
16 Solr: don't set defType=lucene in URLs if extraArgs already defines it.
20 Add lock/unlock for YAZ log writes YAZ-843
24 Fix incorrect parsing of URLs @:9999/somebase&url=http://some.host YAZ-842
28 yaz-client: deal with excess bytes HTTPS case YAZ-833
30 ZOOM C: deal with excess bytes HTTPS case YAZ-833

42 Fix zebrasrv [warn] ir_session (exception) YAZ-838
44 Document itemorder-setname and list all ILL options
48 Extend get_org_info (snippets) to return original string YAZ-836
49 Two new functions have appeared: icu_chain_get_org_info2 and
50 icu_iter_get_org_info2 with a 4th parameter being a pointer
51 to the original string.
53 Fix tcpip.c compilation failure on VC9 YAZ-835
55 Fix icu_iter_get_norm returns invalid size for some input YAZ-834
56 The icu_iter_get_org_info returns information based on string
57 as it appears on tokenize step.
61 Deal with excess bytes in HTTP response for keepalive YAZ-830
63 Refactor ssl_put and tcpip_put to one function YAZ-832
65 Refactor ssl_get and tcpip_get to one function YAZ-831
67 Fix SEGV yaz-client for HTTP decoding error YAZ-829
69 Fix buffer overflow in cmd_elements in yaz-client YAZ-828
73 Fix test_sru.sh fails in pazpar2 YAZ-826
74 Unfortunately a regression occurred with YAZ 5.10.0 that would make
75 Pazpar2 fail for HTTP connections.
79 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
80 Introduce cs_create_host2 which returns if connection should be
81 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
82 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
84 Fix http proxy fails with yaz-client YAZ-824
88 Fix 0 ptr reference for OPAC records from XML YAZ-822
92 Extend yaz daemon facility to assist int log rotation YAZ-818 YAZ-819
96 record conv: 'select' return org record if no x-path match YAZ-814
98 retrieval: pick matched element-set rule YAZ-813
100 Fix crash in record conv rule 'select' YAZ-812
104 record_conv: selection by X-Path YAZ-811
105 That's a new step in record conversion system (<select path=".."/>)
107 Document record render parameters for ZOOM - including base64
111 Fix application/x-www-form-urlencoded + empty YAZ-810
112 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
113 and empty content was supplied.
115 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
117 Fail hard if Bison is not found and is needed YAZ-808
121 Enable YAZ backtrace for programs YAZ-802
123 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
124 Libxml2 2.9.2, Libxslt 1.1.28.
126 Fix daemon: parent process stops before child YAZ-806
127 Try to fix the situation where parent process stops before
128 child has acknowledged it .. SIGUSR2 back!
130 daemon: log message when keepalive stops.
134 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
135 would make yaz-marcdump crash when from-character set was issued.
139 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
140 New function yaz_enable_panic_backtrace which enables backtrace
141 handler for current process. The handler will call backtrace always,
142 then gdb to provide as much detail as possible.
146 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
147 and ZOOM record render will inspect leader 9 and switch to UTF-8
148 (Unicode) if that holds 'a'. This changes behavior, but is considered
149 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
151 Fix cs_put may reconnect if send fails. YAZ-798
155 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
159 Extended comstack with outgoing IP YAZ-795.
160 For cs_create_host + cs_create_host_proxy the vhost may be followed
161 by a outgoing host/IP. Separator is blank.
165 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
166 linker error with yazpp on Windows.
170 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
172 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792

176 Fix annoying warning about wrbuf_putc on newer GCC YAZ-789
178 Fix documentation about --installa option YAZ-788
182 daemon: properly report when receiving SIGUSR2 from child YAZ-785
186 xmalloc: throw assert for clearly invalid calls to malloc and
187 improve diagnostics YAZ-783 YAZ-784
191 Stop building debs for Ubuntu raring, quantal, oneiric.
193 CCL YAZ-781: for multiple use attributes in a specification the
194 generated RPN will perform @or on each term.
195 For spec: term u=31 u=1016
196 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
198 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
200 CCL YAZ-779: combo qualifier should allow for forward references
202 Fix buildconf.sh, automake too old on centos5 YAZ-778
203 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
204 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
205 accepts it without a warning.
209 GFS: client_query_charset conversion YAZ-777
210 This is a feature for Z39.50 clients that sends queries that are not
211 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
212 encoding given to UTF-8.
214 Echoed SRU arguments support YAZ-776
215 This is achieved with new function yaz_srw_get_pdu_e.
217 ZOOM: expire times set for redis/memcached YAZ-772
218 For both redis and memcached option --expire=seconds sets expire
219 time for a result-set/search. Default time is 600 seconds (10 minutes).
223 No [rest of output is omitted] limit for yaz_log YAZ-774
225 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
227 For ICU testing, pass -o to yaz-icu. This will test the
228 icu_iter_get_org_info function.
230 Fix null ptr reference for freeReplyObject YAZ-773
234 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
236 RPM: do not build with libmemcached support. The libmemcached library
237 on CentOS 5/6 does not work reliably for us (redis to the rescue).
239 configure: only allow libmemcached version 0.40 or later. That's the version
240 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
241 that's not an option, consider redis.
245 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
247 Fix zoom+memcached: present request out of range YAZ-767
251 CCL: add new qualifier r=omiteq which will omit relation=equals
252 for ordered relations. This should be used in combination with either
255 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
257 Solr: simplify yaz_solr_decode_response
259 Solr: use different local var for string manipulation
261 Solr: Get rid of hardcoded limit of extra_args
263 Solr: encode lucene query type YAZ-736
264 Make sure the queries are treated as traditional "lucene", because that's
267 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
271 Build packages for Ubuntu Trusty Tahr 14.04 LTS
273 wrbuf_cstr: fix off by one error.
275 wrbuf_buf: make it always return non-NULL
276 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
280 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
282 zoomsh: offer option -a apdulog
283 As we're used to from yaz-client and GFS based servers.
285 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
286 existing setting apdulog takes effect.
288 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
293 Add re-entrant CQL/Solr/RPN query conversion functions.
294 The re-entrant functions are: cql_transform_r,
295 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
296 These have same functionality as cql_transform,
297 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
298 return the additional infomration as WRBUF to make them re-entrant.
300 Remove CQL to Solr conversion and base solr_transform_t on
301 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
302 data structure as cql_transform_t.
304 cql2pqf utility allows RPN to Solr conversion
306 Fix assert in ZOOM when http connect fails YAZ-757
308 --- 5.0.22 2014/04/09
310 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
312 wrbuf_cstr: make it thread safe YAZ-753
314 yaz_log_init_file may take fd=<no> to open log file at the FD given.
316 --- 5.0.21 2014/03/21
318 Offer new utility function zget_AttributeList_use_string.
320 New conversion step, solrmarc, for record conversion module.
322 --- 5.0.20 2014/03/13
324 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
325 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
328 --- 5.0.19 2014/03/10
330 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
331 The standalone ZOOM sort was completely broken since 5.0.13.
333 ZOOM: generate event Connect rather than None for partial connect
334 (in fact getaddrinfo resolving).
336 ZOOM: only supply clientIP for InitRequest. Rather than for all
339 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
341 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
342 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
343 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
345 New "Facets" section in the documentation.
347 --- 5.0.18 2014/02/27
349 Call exsltRegisterAll in yaz_init_globals, so that all applications
350 using YAZ will have EXSLT things enabled.
352 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
354 Update various URLs to the re-organized SRU pages at LoC.
356 --- 5.0.17 2014/02/26
358 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
359 introduced in 5.0.12.
361 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
362 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
363 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
366 --- 5.0.16 2014/02/25
368 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
370 --- 5.0.15 2014/02/24
372 Fix gcrypt not properly initialized YAZ-740.
374 --- 5.0.14 2014/02/19
376 Describe memcached option for ZOOM.
378 ZOOM: throw present request out of range again YAZ-739
379 Was removed in YAZ 5.0.13.
381 --- 5.0.13 2014/02/18
383 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
384 with localtime_r when threads + fork is used (such as Metaproxy).
386 yaz-config: quote some RHS values (that might include blanks)
388 zoomsh: shows SearchResult-1
390 zoomsh: sortby command
392 zoomsh: use proper list of connections and result sets YAZ-725
394 Avoid yaz_log in sigterm handler for GFS YAZ-737
395 Logging is still performed, but outside sig handler.
397 New ZOOM C feature: result-set caching with memcached. Example:
398 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
400 Remove SSL via OpenSSL support YAZ-732
401 Also deprecate two functions from comstack that aren't working with
402 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
404 Revert "Bison: use %name-prefix directive rather than -p option"
406 --- 5.0.12 2014/01/22
408 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
410 SRU GET/Solr base URLs may hold additional ?args YAZ-729
411 ZOOM option extraArgs already does this, though. It seems useful
412 when dealing with Solr targets to limit by filter, eg.
413 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
415 Remove #fragment for HTTP request encoding YAZ-730
417 Doc: Update list of DLLs/LIBs
419 Doc: update href link to Unix utils and Git.
421 --- 5.0.11 2014/01/15
423 ZOOM: fix "lost connection" problem with servers that uses both squid
424 and another proxy behind it that returns Location headers with relative
427 zoomsh: do not use readline for stdin (no tty) YAZ-724
428 Just use fgets in that case. If the user hits Ctrl-D a new-line
431 zoomsh: empty command ignored YAZ-723
432 rather than performing exit of zoomsh.
434 yaz-url utility offers option -v to enable verbose mode.
436 yaz_url uses yaz_check_location and offers verbose mode.
438 Add new function yaz_check_location.
439 This function gets an absolute URI from Location (HTTP redirect).
441 cookie API: introduce yaz_cookies_reset
443 Update cql.y for newer bison YAZ-720
444 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
445 longer supported. Instead one must use %lex-param and %parse-param .
447 --- 5.0.10 2014/01/09
449 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
452 rpn2solr: support truncation left(2), left&right(3) YAZ-718
454 Mention SRU version 2.0 in yaz-client man page.
458 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
463 Make cs_parse_host public.A
465 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
466 introduced in YAZ 5.0.6.
470 Fix buffer corruption for yaz-ztest record fetch.
474 Allow yaz-ztest to return user-defined records (one record per file).
475 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
477 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
478 Use the stream write instead of odr_printf which has a 4K tmp buffer.
480 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
484 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
485 can read and write this format. For record format JSON, yaz-ztest returns
486 MARC-in-JSON records.
488 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
489 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
493 Improve error reporting for ICU chains YAZ-707
494 Report config element+rule when ICU status is "failure".
496 ZOOM: stop fetching if present response has no records YAZ-710
497 Some targets return less records than their hit count would suggest.
498 This prevents ZOOM from continuing to fetch records if any present
499 response has 0 records in the response.
501 Ensure that GFS calls exit if any listener fails YAZ-710
502 Before, if XML config was in use, it would start the default
507 yaz-ztest: -V shows version (like yaz-client -V)
509 New iconv encoding: danmarc YAZ-692
511 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
513 daemon: only wait for immediate child rather than all children. YAZ-704
515 yaz-client: fix setting of SRU record schema. If scheme was unset, it
516 could lead to invalid memory reference.
520 yaz-ztest returns schema for MARCXML test records. SRU require that
521 recordSchema for records.
523 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
524 instead of non-surrogate diagnostic. This is a per-record failure.
526 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
527 may refer to multiple listeners now. Attribute listenref is a comma separated
530 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
531 option is given for GFS, the dirname of filename (for -f) is used
532 as prefix for options such as cql2rpn, ccl2rpn, etc.
534 Content-Type charset fixes YAZ-701 . Do not inspect charset in
535 Content-Type header for SOAP when decoding SRU. The payload (XML)
536 itself tells what encoding it is. In response, never supply encoding
537 in Content-Type. The response payload (XML) tells what it is (with no
538 encoding in XML it's UTF-8).
540 HTTP decoding: allow blanks in URL paths YAZ-700
544 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
545 and facets. Ensure recordData and recordSchema are always present in
546 record element, because they are required.
548 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
551 Simplify in a lot of places using odr_strdupn.
553 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
557 Increase various buffers in GFS's statserv_options_block
558 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
559 This change makes many type-casts redundant, and, thus simplifies code.
561 Remove last bits of WAIS support.
563 Remove member 'size' from Odr_oct.
565 Slim down the public part of 'struct odr'. Most elements are not part
566 of struct Odr_private.
568 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
569 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
570 In particular facets are supported in both client - and server side.
571 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
572 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
573 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
574 both request/response). This is what a search handler in the GFS
575 will see (regardless of whether operating in SRU mode or Z39.50).
577 Changes to the srw.h (SRU/Solr) definitions include:
578 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
579 (char*), which replace union query and query_type (int). This is because
580 SRU 2.0 supports a queryType parameter. This also means that, to carry
581 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
582 x-pquery=PQFstring (extention parameter). The extension parameter
584 - New element, packing, that has information about SRU
585 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
587 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
589 New element, packing, in Z_SRW_explainRequest.
591 New elements in Z_SRW_scanRequest, queryType and scanClause.
592 These replace query_type and scanClase untion. This is similar to what
595 --- 4.2.69 2013/10/01
597 GFS: log when closing down - at least SIGTERM YAZ-684
598 Also change formatting WRT PID logging a bit.
600 Improve display of MARC records with multi-byte subfield IDs YAZ-695
601 In some rare cases subfield identifiers are multi-byte characters.
602 This will try to deterime length of those and split accordingly.
603 This affects display in line mode as MARCXML/MarcXchange. The encoding
604 of ISO2709 is the same.
606 Change inp argument to const for yaz_read_UTF8_char.
608 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
610 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
612 Better check of marc leader info YAZ-691
613 Problem is that some systems generate MARCXML/MarcXchange with
614 funny headers. These will not work if encoded as ISO2709.
615 Some tests produce new output, due to updated warning messages
617 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
619 yaz-client: display MAB records YAZ-689.
620 Thanks for Heiko Jansen for this patch.
622 New utility z_get_HTTP_Response_server which allows both HTTP server name
623 and HTTP server URL to be given in response.
625 Debian: do not depend on obs tcl8.3.
627 Debian: do not depend on obs libicu36-dev.
629 --- 4.2.68 2013/09/23
631 GFS: pass additionalSearchInfo to search memeber search_input if
632 given. Otherwise pass otherInfo. Request for facets and other search
633 related things will be passed there in future versions of YAZ.
635 New ZOOM setting, authenticationMode, which allows authentication
636 paramters to be encoded in the URL rather than via HTTP Basic auth.
639 rpn2solr: fix nested AND/OR handling. YAZ-685
641 Add comparison routines for some Z-types, such as NamePlusRecord,
642 RPNQuery, Query, RecordComposition and OtherInformation.
644 --- 4.2.67 2013/09/19
646 Don't decode MAB as MARC. Just like we don't attempt to decode
647 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
649 CCL: allow quoted terms for date ranges. YAZ-681
651 Introduce ccl_parser_qual_search. This function makes old function
652 ccl_qual_search, from YAZ 2, available again.
654 Add yaz_facet_list_to_wrbuf. YAZ-683
656 --- 4.2.66 2013/09/11
658 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
659 schema was given for search. YAZ-675
661 Add Solr date range searches. YAZ-621
663 --- 4.2.65 2013/08/22
665 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
667 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
669 ISO2709/MARC parse most octet aligned records; not just those that
670 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
671 MARC parse more records instead of just dumping as is. YAZ-670
673 ZOOM: proper caching for variations of record schema. YAZ-671
675 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
677 --- 4.2.63 2013/07/17
681 --- 4.2.62 2013/07/11
683 New utility z_get_HTTP_Response_details - an extended version of
686 New utility yaz_url_get_error which returns error message of last
687 failed yaz_url_exec call.
689 yaz-url and url functions: allow max HTTP redirects to be controlled.
691 New functions yaz_file_glob2, yaz_xml_include_glob.
692 These functions takes a flags parameter, which, for now only controls
693 whether to fail inclusion of a non-existing file (without glob
694 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
696 --- 4.2.61 2013/06/20
698 For MARC XML parsing, allow record without leader. A fake/default leader
699 is inserted and a warning is tagged with the record.
701 ICU: fix leak in in icu_iter_get_org_info.
703 --- 4.2.60 2013/06/14
705 ICU: fix bug in icu_iter_get_org_info (un-init variable).
707 --- 4.2.59 2013/06/11
709 Implement z_HTTP_header_remove.
711 --- 4.2.58 2013/06/11
713 ICU: Disallow 0 ptrs for some ICU string utilities.
715 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
716 returns original tokens (before normalization).
718 CCL: avoid z39.58/regex truncation when not needed. Apply only the
719 conversion of those masks, when absolutely necessary.
721 CCL: configurable masking character - @mask. Default masking character
724 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
725 full response anyway, so a Transfer-Encoding header will obstruct the
728 --- 4.2.57 2013/05/15
730 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
731 picking a socket. Problem is that some systems has IPV6 support, but
732 we can't create sockets for them, so we pick AF_UNSPEC first.
734 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
735 use content_len to determine resulting Content-Length in HTTP response
736 and NOT Content-Length supplied in headers by user.
738 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
739 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
741 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
744 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
745 with big endian and unsigned char (by default).
747 --- 4.2.56 2013/04/26
749 Fix yaz-client connect (crash in 4.2.55).
751 --- 4.2.55 2013/04/26
753 Fix proxy/host problem for ZOOM that could occur if unix sockets
756 New Debian package libyaz4-dbg.
758 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
759 differently in tcpip_close.
761 --- 4.2.54 2013/04/17
763 Windows installer of YAZ includes YAZ4J as a component.
765 CQL: allow "extra terms" again, by default. Thus, the CQL parser
766 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
767 and earlier. CQL parser may operate in strict mode where queries
768 not conforming to the standard BNF are rejected (syntax error).
769 Whether the CQL parser operates in strict mode is controlled with
770 cql_parser_strict . Strict mode enabled with option -S for utilities
771 cql2pqf and cql2xcql .
773 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
775 --- 4.2.53 2013/04/10
777 New charset, MARC-8c, which is like MARC-8 but allows control characters
778 0x01 through 0x1F, except ESC to be passed through verbatim.
780 Fix a problem with duplicate sub field character in MARC output. Problem
781 happened only when output was MARC-8 encoded.
783 --- 4.2.52 2013/04/03
785 yaz-ztest: Use hash for fake hit count. Before, random number was used.
786 This is problematic for unit tests using yaz-ztest. This patch also makes
787 a hash for CQL queries. For RPN, any term with a leading digit will be
788 treated as pseudu hit count (to force any particular hit count by a client).
790 yaz-ztest: return unique MARC dummy records. Beyond record offset
791 24, the author surname is patched with offset to make all records
794 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
795 on system wide default (/proc/sys/net/ipv6/bindv6only).
796 @4 binds to IPV4 only. @6 binds to IPV6 only.
798 Update CQL API documentation a bit
800 CQL: don't accept extra terms for queries. Makes the CQL parser
801 stricly conformant to the standard.
803 --- 4.2.51 2013/02/12
805 GFS: scan handler gets extra_args from request and may return extra
806 response data . That's for SRU only.
808 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
810 --- 4.2.50 2013/01/30
812 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
814 OPACXML: sync spelling of availabilityDate in XML to that of Schema
815 opaxxml.xsd. The schema had the correct spelling of this member always.
816 The ASN.1 was mis-spelled and still is (API change) - we are
817 not changing this. However, the OPAC to XML conversion had yet
820 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
823 New function, z_ext_record_oid_nmem, which is similar to
824 z_ext_record_oid but takes NMEM rather than ODR
826 --- 4.2.49 2013/01/18
828 ICU: New conversion element 'join' which joins tokens into one
829 with a custom character given by rule attribute.
831 --- 4.2.48 2013/01/10
833 New GFS search member: present_number. This is a hint to the
834 search handler how many records are going to be fetched immediately
835 following search. There's no guarantee that it's going to be the case,
836 since it depends on hit count (for Z39.50 piggyback) and whether errors
839 Make a few functions static (private). The functions getbyte_stream,
840 ungetbyte_stream and yaz_gets are now private. They were never declared
843 yaz-marcdump: exit(5) for serious decoding errors
845 ISO2709 decoding: be more picky WRT header
847 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
848 was only used as to indicate that next-result-set-position should be
850 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
851 Based on patch from Ashley Sanders.
853 Make some functions static/private in PQF parsing. Those functions were
854 never declared in a public header and so should not be in use by
855 applications based on YAZ.
857 --- 4.2.47 2012/11/23
859 ZOOM: special options to control APDU logging.
860 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
861 logging of APDUs until "saveAPDU" option is set again. If logging is
862 already enabled the effect is that current APDU buffer is cleared.
863 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
864 logging (default behavior on new connection).
865 The APDUs sent/received can be obtained by using
866 Using ZOOM_connection_option_get(c, "APDU") or
867 ZOOM_connection_option_getl(c, "APDU", &l).
869 GFS: relay implementation_version from backend
870 From 3.0.40 and later, implementation_version from backend was
871 not used in init response at all.
873 --- 4.2.46 2012/11/15
875 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
876 mode at all. Probably never did.
878 Make a new version of ztest.pem that, at least, is not expired.
880 --- 4.2.45 2012/11/13
882 Fix description of CCL directive 'case'.
884 More tight checking of form arguments (yaz_uri_to_array). Makes
885 YAZ better at rejecting big and/or bad POSTs.
887 SRU decoding does not report more than up to 10 invalid arguments.
889 rpn2cql: less quotes in generated terms. Semantics unchanged, but
890 it's prettier this way.
892 --- 4.2.44 2012/10/25
894 New utility yaz_decode_init_diag. Defined in proto.h.
896 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
897 given for unix local socket.
898 The COMSTACK string for doing so is:
901 unix:/myfile:tcp:localhost:9999/mybase
902 unix:/myfile:localhost:9999/mybase
903 unix:/myfile:http://fakehost/mybase
905 debian: Use dpkg-buildflags in build process.
907 --- 4.2.43 2012/10/19
909 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
910 global's SRU service uses a recordPosition scheme starting from zero.
911 First record's position should be one
912 according to the standard.
914 --- 4.2.42 2012/10/18
916 Allow more namespaces for SRU. This is to allow, for example, an
917 incorrect namespace returned from server
918 http://services.igi-global.com/sru .
920 Minor fixes for compilation on Windows.
922 --- 4.2.41 2012/10/11
924 daemon: log total number of bad signals from child on stop so that it
925 is more easy to spot problems with child worker processes.
927 retrieval: empty backend name attribute omits element set
928 from being used in retrieval.
930 --- 4.2.40 2012/10/04
932 Implement Solr sort strategy "solr", similar to sru11 sorting.
933 This will implement the correct parameters on Solr requst to do
936 --- 4.2.39 2012/09/28
938 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
941 MARC: Extra/missing indicator handled for MARCXML.
942 The indicator length is given in header and is the same for the
943 whole record. If attributes ind1, ind2 are missing, then content
944 character defaults to blank. Extra indicator attributes (beyond)
945 indicator length are treated as an error.
947 Reformat: delete trailing whitespace
949 --- 4.2.38 2012/09/17
951 MARC: fix non-ASCII characters for leader. This is to ensure we can
952 generate XML in UTF-8.
954 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
955 in one node with structure word.
957 --- 4.2.37 2012/09/04
959 yaz-json-parse: JSON output may be pretty printed by using option
962 Increase default value of max message for Z39.50 Init for GFS, ZOOM
963 and yaz-client. Old value was 1 MB. New value is 64 MB.
965 --- 4.2.36 2012/08/22
967 yaz-client: don't display bogus records from SRU servers. Some SRU servers
968 return more records than given by *maximumRecords*. Skipping those in
971 record_render: simplify buffer return handling and fix at least one bad
972 memory reference, that broke the test_embed_record sometimes.
974 Allow http://user:pass@host notation for yaz_url_exec.
976 zoomsh: allow shell command to be executed. Via the system(3) call.
978 yaz_poll: Allow num_fds == 0
980 yaz-client: fix bad encoding of "itemorder item". The itemorder
981 item <no> - command forgot to use length of encoded Item Request
982 package. Error present since YAZ 3.
984 yaz-ztest: fix bad usage of session handle. Bug was introduced when
985 result sets were saved (271a9c83).
987 SRU recordPacking: guess record packing in response rather than looking
988 at the recordPacking element which, OF COURSE, changed semantics in SRU
991 Decode SRU 2.0 responses. The official namespace for responses, according
992 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
993 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
994 nature.com's server, however, usee namespace
995 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
996 we are now using a glob-expr to match up the namespace. ZOOM C and
997 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
998 I can not find a single real example showing the "real" namespace in
999 the documentation from OASIS. The namespace for requests is different
1000 from responses, but this is not added to YAZ yet, when we don't encode
1003 --- 4.2.35 2012/06/26
1005 zoom/record_render: add support for Base64 decoding fo MARC records
1006 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
1007 which will decode base64 + ISO2709 marc-8 encoded material from text node
1010 --- 4.2.34 2012/06/07
1012 Add missing definitions ZOOM_resultset_get_facet_field_by_index
1013 and ZOOM_resultset_facets_names.
1015 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
1018 Change APDU dump printing to avoid long leading blanks. For levels 16
1019 or larger the level is shown and the indentation is truncated but
1020 recursed with modula 8. This makes it still reasonable easy to read
1021 - even for nested BER dumps.
1023 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
1024 return 0 (incomplete package) in case where the BER package was
1025 considered too nested (return value of -2).
1027 dumpber: lines of level 15 are not indented further. Two spaces per
1028 indentation; indentation 15 or more is indented to a fixed indentation
1029 and augmented with a level=<no> indication.
1031 zoomsh: increase max size of command+args
1033 GFS: No limit in RPN buf size in CQL to RPN conversion.
1035 --- 4.2.33 2012/05/09
1037 New function for daemon utility, yaz_daemon_stop .
1039 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
1041 --- 4.2.32 2012/04/25
1043 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
1044 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1046 --- 4.2.31 2012/04/23
1048 YAZ daemon utility relays SIGUSR1 to child process.
1050 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1051 would result in en empty database list - which in turn would result in
1052 encoding failure for search.
1054 Fix reading beyond string in yaz_sort_spec.
1056 --- 4.2.30 2012/04/11
1058 Add two new SRU diagnostics:
1059 236: Access to specified database denied
1060 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1062 Document the very useful ZOOM-C option "apdulog".
1064 CQL to RPN: term may be passed through verbatim. This is enabled with
1065 truncation.cql . The assumption being that the term is already CQL.
1067 --- 4.2.29 2012/03/20
1069 record_conv: leader spec may be given for marc element.
1070 The leader spec is given as attribute leaderspec for element marc.
1071 For example to convert a MARC21 record from MARC-8 to UTF-8:
1072 <marc inputformat="marc" outputformat="marc"
1073 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1075 record_conv: allow user-XSLT params. For example:
1076 <xslt stylesheet="MARC21slim2DC.xsl">
1077 <param name="myparameter" value="myvalue"/>
1078 <param name="otherparameter" value="othervalue"/>
1081 record_conv: fix error handling for missing marc charsets.
1083 CQL: fix extra terms in wrong order.
1085 --- 4.2.28 2012/03/06
1087 record_conv: modify new API for conversion types. The conversion types
1088 may be passed in new functions yaz_record_conv_configure_t and
1089 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1091 Avoid mixed statement/variable declare; fixes compilation with Visual
1094 --- 4.2.27 2012/02/28
1096 Add non-standard SRU diagnostic: 235: "Database does not exist".
1097 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1098 Update SRU to Bib-1 diagnostic maps accordingly.
1100 CCL: add two new diagnostics for unsupported masking. The new
1101 diagnostics are: "Embedded truncation not supported" and
1102 "Single charcacter mask not supported".
1104 --- 4.2.26 2012/02/23
1106 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1108 --- 4.2.25 2012/01/11
1110 Build YAZ for Ubuntu Oneiric.
1112 CCL: allow parantheses for proximity operands. For example CCL query
1113 (a) % (b) is now allowed.
1115 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1116 marked dead, rather then being destroyed. If not, the session memory is
1117 being free'd before the search/scan handler is finished. Also destroy
1118 'request' memory in request_release rather than in various places,
1119 which resulted in leaks from time to time.
1121 --- 4.2.24 2011/12/21
1123 cql_sortby_to_sortkeys: honor sort prefix.
1125 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1126 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1127 The rpn2cql family of functions now always returns quoted CQL terms.
1129 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1131 --- 4.2.23 2011/12/15
1133 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1134 sequence is treated as one. For example, &&a=b&&&c& is identical to
1137 --- 4.2.22 2011/12/05
1139 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1140 APDUs for a connection to a WRBUF.
1142 --- 4.2.21 2011/11/23
1144 Fix cql_sortby_to_sortkeys. Completely broken before.
1146 Make CCL's @truncation work again.
1148 --- 4.2.20 2011/11/09
1150 New ZOOM connection setting: tproxy. It's like proxy, but does not
1151 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1152 to set resolved address + port for a connection outside ZOOM itself.
1154 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1156 --- 4.2.19 2011/11/07
1158 Fix uninitialized variable in Solr spell support (could cause SEGV
1159 for SRU response decoding).
1161 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1162 back-end's addinfo through into the ZOOM response addinfo.
1164 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1165 they are separated by a colon and a space rather than simply
1168 --- 4.2.18 2011/10/28
1170 Add support for Solr spell-checking/suggestions through ZOOM.
1171 If a Solr target has been configured correctly for spelling-checking
1172 and suggestions, these will now be returned on the ResultSet option
1173 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1175 --- 4.2.17 2011/09/28
1177 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1178 with a flag whether to substitute escape sequences or not.
1180 --- 4.2.16 2011/09/22
1182 Fix nmem_strsplit_escape to substitute escape char properly.
1184 New option for zoomsh -e , which makes it abort on first error and
1185 return process exit code to indicate success/failure.
1187 YAZ options utility supports special option -- which makes all it treat
1188 all following arguments as non-options.
1190 --- 4.2.15 2011/09/16
1192 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1193 searched if absolute filename is given.
1195 Fix conv_xslt() error-reporting when stylesheet is not found.
1196 (The value of fullpath is meaningless in this situation.)
1198 --- 4.2.14 2011/09/07
1200 Fix problem in CQL sort node creation: un-initialized memory.
1202 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1203 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1204 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1207 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1208 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1210 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1211 will make it possible to use both single-character mask (#) and wildcard (?)
1212 in CCL . Throw diagnostic for left truncation because that is not supported
1215 --- 4.2.13 2011/09/01
1217 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1218 cases using escapes (\-sequences) and masking.
1220 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1221 would result in a read one byte beyond string.
1223 rpn2ccl may use Z39.50 masking for terms (t=z).
1225 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1227 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1228 not --cppflags (which seeems like an error in icu-config).
1230 --- 4.2.12 2011/08/27 RPM package only
1232 cql2ccl: fix conversion of terms: operator characters were not
1235 --- 4.2.11 2011/08/25 RPM package only
1237 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1238 CCL parser will map both # and ? to their regular expression
1239 quivalents (. and .*).
1241 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1242 of reserved CQL characters.
1244 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1245 is, so that they are passed through.
1247 --- 4.2.10 2011/08/24
1249 ZOOM SRU mode: more aggressive re-connect.
1251 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1252 made available as a utility function, declared in <yaz/logrpn.h>
1254 rpn2cql_structure() supports proximity nodes (except that the Type-1
1255 proximity node's "exclusion" binary is ignored, as there is no way to
1256 express that in CQL). Fixes bug #4564.
1258 --- 4.2.9 2011/08/18
1260 Fix SEGV that could occur if set command of zoomsh was given without
1261 value (2nd argument).
1263 Fix SEGV that could occur if unsupported transport was given for
1264 COMSTACK - say https (when SSL was unavailable).
1266 Build yaz-url on Windows too.
1268 --- 4.2.8 2011/08/11
1270 New utility to get web content. Header is url.h. A command line tool
1271 yaz-url is part of the distribution and packages.
1273 Fixes for SSL COMSTACK (when gnutls is in use).
1275 New functions yaz_base64{encode,decode}. Header is base64.h.
1277 --- 4.2.7 2011/08/03
1279 ZOOM C includes HTTP response buffer as additional info if it fails
1280 to decode the SRU response.
1282 Make wrbuf_json_puts available.
1284 --- 4.2.6 2011/07/28
1286 zoom: throw diagnostic for invalid value for option "sru". Before a
1287 bad SRU request was sent.
1289 Adding new utility wrbuf_vp_puts.
1291 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1293 --- 4.2.5 2011/07/21
1295 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1296 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1297 redirect was used at the same time.
1299 MARC line mode decoding: be less picky about length given - first
1300 5 digits of header that is.
1302 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1304 Changes to decoding of SRU records: a record with recordPacking=xml is
1305 modified with a new root element <yaz_record> if the recordData contains
1306 multiple children elements. This is to make the record XML parseable
1309 RPN to Solr conversion: encode special characters.
1311 Generic Frontend Server: fix uinitialized member, stepSize.
1313 --- 4.2.4 2011/06/21
1315 Fix a bug in SRU decoding of records.. The database records stored
1316 had un-initialized memory, but it would only be seen with yaz_record_render
1317 and type_spec="ext" .
1319 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1321 --- 4.2.3 2011/06/17
1323 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1325 --- 4.2.2 2011/06/10
1327 Add new utilities to convert from CQL to CCL . These utilities have
1328 prefix cql_to_ccl defined in cql.h.
1330 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1331 lead to memory heap corruptions when ICU utilities were in use.
1333 --- 4.2.1 2011/06/07
1335 Make compilation work without Libxml2.
1337 yaz-client: remove redundant blanks in display of searchResult-1 term
1340 --- 4.2.0 2011/05/18
1342 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1343 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1345 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1346 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1347 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1348 Note that the CQL sortby spec is only converted when the GFS is already
1349 converting from CQL to RPN (cql2rpn element).
1351 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1352 specify whether to collapse delimitors or not. The existing nmem_strsplit
1353 do collapse (collapse parameter = 1).
1355 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1357 Rename internal func yaz_use_attribute_create. While non-static, this
1358 function is not declared in a public header.
1360 --- 4.1.7 2011/03/15
1362 Add -lCrun when linking with ICU on Solaris.
1364 More quicks character set conversions for OPAC records.
1366 --- 4.1.6 2011/03/10
1368 fix problem with record_render: records were converted (character set
1369 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1371 --- 4.1.5 2011/03/08
1373 SRU: add methods for handling DADS SRU-proxy facets.
1375 Separate OPAC record character set for ZOOM_record. yaz_record_render
1376 allows a character set given as charset=from/opacfrom,to where 'from' is
1377 the character set of a bibliographic record, 'opacfrom' is character set
1378 of OPAC record and 'to' is the target character set.
1380 --- 4.1.4 2011/02/21
1382 yaz-client: show may XML format records. Command show followed by 'format'
1383 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1386 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1389 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1391 --- 4.1.3 2011/01/27
1392 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1394 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1395 this package can be distinguished from other vendors.
1397 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1398 as determined by configure
1400 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1402 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1403 returns no error and no record, the present request is considered
1404 partial (only a subset of the records could be returned by backend), and
1405 so it is appropriate to set Present Status to partial-4.
1407 --- 4.1.2 2010/11/02
1409 Move yaz-config man pages to section 1.
1411 More documentation about Solr.
1413 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1414 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1415 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1416 peers on some Linux systems. However, in general that does not work
1417 so YAZ can not rely on that to work. Debian changed behavior in this
1418 respect from Debian lenny to Debian squeeze (still testing as of Oct
1420 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1422 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1424 --- 4.1.1 2010/10/05
1426 Fix yaz-config output: echo_source not set correctly by configure.
1428 --- 4.1.0 2010/10/05
1430 Solr Web Service support for yaz-client and ZOOM.
1432 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1434 --- 4.0.12 2010/08/17
1436 Z39.50 facet support. Facet specifications are passed for search in
1437 other-information with ASN.1 as defined in facet.asn and OID
1438 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1439 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1440 3 is limit (number of entries to get in response). yaz-ztest returns
1441 dummy facets if a client asks for them.
1443 --- 4.0.11 2010/07/09
1445 CCL fixes: bug 2895 and bug 3539.
1447 GR1-display: add comma in display - was removed by mistake in
1450 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1452 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1454 --- 4.0.10 2010/06/18
1456 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1457 result set from a connection. The result set will be on its own
1458 thereafter; no operations on it will perform retrievals from a target.
1459 Only cached copies are returned.
1461 ZOOM C:fix case for HTTP servers responding with Connection:close.
1462 Ensure that if there is a current task it is resumed (like fetching
1463 more records in a result set) . Bug #3484.
1465 PQF parser: use odr_atoi for Odr_int (not atoi)
1467 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1468 values that contain any non-digits are treated as string attributes
1469 (previously decoding only checked for leading character ([0-9]). PQF
1470 encoding: attribute string values are not surrounded by double-quotes.
1472 --- 4.0.9 2010/05/21
1474 New utility for managing threads - thread_create.h.
1476 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1477 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1478 but YAZ' implementation do.
1480 Fixes for yaz_cond-functions on Windows 7.
1482 DLL export more symbols.
1484 zoomsh: show record do NOT render opac.
1486 Remove *.la files from Debian and RPM packages.
1488 --- 4.0.8 2010/05/11
1490 Debian package libyaz-dev depends on libgnutls-dev again (was
1491 removed in YAZ 4.0.6, but due to Libtool it is still needed
1492 even though yaz-config do not list libgnutls libs).
1494 ZOOM: Use only one WRBUF for returning string results for
1495 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1497 ZOOM: ZOOM_connection do not use a shared pointer to
1498 ZOOM_resultset after ZOOM_resultset is destructed by
1499 user. Reverts to YAZ 4.0.4 behavior.
1501 --- 4.0.7 2010/05/04
1503 record-conv: fix problem with at least one XSL conversion -
1504 due to probably incorrect usage of XML XSL documents.
1506 --- 4.0.6 2010/04/29
1508 Fix yaz-config for static mode and the use of SSL (gnutls).
1510 --- 4.0.5 2010/04/29
1512 Forward decl timeval struct in mutex.h and gettimeofday.h.
1514 yaz-config: fix 'static' mode linking.
1516 --- 4.0.4 2010/04/28
1518 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1519 are wrappers for pthreads or Windows. For Windows these are put in
1520 a separate DLL: yaz_cond4.
1522 libyaz.la (whole source) is compiled with thread. If thread support
1523 is enabled enabled, all source of YAZ is compiled with treading support.
1524 This allows core utilities such as yaz_log to use thread facilities.
1525 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1526 thread utilities. This commit moves mutex utilities (mutex.c) from
1527 libyaz_server.la to libyaz.la.
1529 yaz-json-parse displays leading text until error.
1531 --- 4.0.3 2010/04/09
1533 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1534 patch from Giannis Kosmas.
1536 SRU: no longer URL encode SRU database. The URL for an SRU server is
1537 a URL and such is alreeady encoded - at least when given with leading
1538 http:// or https://. This reverts behavior to YAZ 3.0.50.
1540 Support for new MARC XML notation TurboMARC which like MARCXML is a
1541 complete representation of MARC/ISO2709.. This one, however, is more
1542 compact and allows for faster processing with XSLT. TurboMARC can be
1543 used in the marcdisp.h API, from the yaz-marcdump utility and from
1546 yaz-ztest can be configured - via the database - to perform certain
1547 delays when it performs operations search, present and single record
1548 fetch. This allows testers to make yaz-ztest act as a real or even slow
1549 Z39.50 server. Refer to the yaz-ztest man pages for details.
1551 --- 4.0.2 2010/03/09
1553 wrbuf_destroy allows NULL WRBUF passed to it.
1555 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1557 Add ZOOM_connection_close.
1559 No fixed size buffers for ZOOM shell - bug #3257.
1561 tstodr: make it work on s390 platform.
1563 New icu iterator-functions. The new icu_iter-functions makes it possible
1564 to use ICU chains from many threads.
1566 yaz-client: better syntax check for show command.
1568 --- 4.0.1 2010/01/26
1570 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1573 New simple local-file XML include facility which allows file glob-patterns.
1574 Refer to yaz/xml_include.h.
1576 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1579 ZOOM_record_get supports new parameter "format" which makes it format XML
1582 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1583 JSONText in ECMA-262) is JSONValue, not JSONObject.
1585 --- 4.0.0 2010/01/20
1587 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1588 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1590 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1591 POSIX/Unix builds .so with major version 4.
1593 Remove old LOG_-defines from log.h. They have been obsolete and
1594 undefined by default for the last 5 years.
1596 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1598 GFS: Remove socket (int *fd) from search_rr handler. The socket
1599 descriptor ptr is a facility that allowed a search handler to supply
1600 a socket which would serve as a callback - when search was complete.
1601 This facility has now been in use for years.
1603 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1604 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1605 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1606 returns 'const char *' rather than 'char *. The returned string is
1607 read-only and should not be modified by applications. COMSTACK cs_close is
1608 now a void function - it no longer returns int. No applications check for
1609 the value and the implementations has always returned 0.
1611 ZOOM: use size_t for scan hit counts and str size. Functions
1612 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1613 occ (hit count) and len (string length) are now of type size_t pointer
1614 rather than int pointer. This is to be able to represent large hit counts
1615 and to also just to use the proper type for string length (strlen result).
1617 New JSON parser. Refer to include/yaz/json.h .
1619 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1620 Used to be int in some cases. Many wrbuf_-functions used to return an int
1621 indicating some length.. These return values were never used. And so they
1624 ODR: odr_malloc, odr_total now takes size_t for size.
1626 clone_z_type: fix leak; occurred for encoding failures.
1628 --- 3.0.52 2009/12/03
1630 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1631 bug was introduced in 3.0.51.
1633 --- 3.0.51 2009/12/02
1635 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1637 tcpip comstack: fix leak for getaddrinfo.
1639 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1640 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1641 Decoding of SRU "path" database is performed by private function
1642 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1643 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1645 yaz-client: honor base command for SRU. Change when database setting
1646 is applied for SRU and ensure it is kept when a connection is reset.
1647 Change also the way errors are displayed or SRU (decoding of packages).
1649 --- 3.0.50 2009/11/02
1651 Add support for extra request / response data for SRU codecs and GFS.
1652 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1653 for extra data response buffer and length. For the GFS, both request
1654 and response data (XML) is carried in extra_args and extra_response_data
1655 for the search handler. Patch by Ko van der Sloot.
1657 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1658 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1659 10010). This fixes bug #2113.
1661 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1662 cmdfile included a 'quit' command that would result in a memory violation.
1664 --- 3.0.49 2009/10/01
1666 Make a number of functions defined in xmlquery.c static. These have
1667 never been declared in a public header file (yaz/xmlquery.h) and was
1668 made public by mistake.
1670 Improve speed of character conversions (iconv utilities). This makes
1671 conversions from MARC-8 faster.
1673 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1674 unless type desired is "raw". This will prevent type "xml" from
1675 returning ISO2709 .. Which obviously can not be XML parsed.
1677 Fix memory leak in ZOOM that would occur if option apdulog was used
1678 on a re-used connection.
1680 Frontend server logs HTTP requests.
1682 Frontend server now sends Z39.50 close when it times out (sesssion has
1683 been idle for too long). Versions 2.0.30 and earlier also sent close.
1684 But due to a mistake this was disabled in all versions after that, i.e.
1685 the server would just close the socket immediately.
1687 yaz-client emits a better message when receiving an unrecognised
1688 userInformationField.
1690 Skip zero-length subfields when decoding ISO2709. This rare case happens
1691 if a record has two FS characters in a sequence. Without this patch
1692 there would be a reference beyond char array in using_code_len fragments
1695 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1697 --- 3.0.48 2009/08/28
1699 The show command offered by the zoomsh command now takes a 3d optional
1700 parameter type which is what is passed to ZOOM_record. If the type
1701 argument is omitted, "render" is used.
1703 RPN to CQL conv may use USE string attributes (bug #2978).
1705 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1707 --- 3.0.47 2009/07/08
1709 Function yaz_xml2query allows a diagnostic element in the PQF XML
1710 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1711 code and additional info respectively.
1713 The BER BOOLEAN is now the integral type Odr_bool which still happens
1714 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1715 typedef'd to Odr_int. This is still an integral 'int', but it may be
1716 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1717 ASN-1 compiler as well as programs has been updated to use the new types.
1719 --- 3.0.46 2009/06/08
1721 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1722 only the bibliographic record was rendered. For type=opac, an OPAC
1723 record is only returned if it is present.
1725 iconv: small fix for encoding of advancegreek.
1727 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1729 yaz-client: option auto_reconnect=on really reconnects.
1731 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1733 server: avoid null ptr ref for for yaz_poll errors.
1735 build: fix RPM build for RHEL 5.3.
1737 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1739 --- 3.0.45 2009/03/31
1741 Fixed bug #2709: TCP connect returns Invalid argument.
1743 Fixed compilation for mingw.
1745 Honor charset for raw records (ZOOM_record_get).
1747 Fixed use of errno for threaded mode that was seen on Solaris 10.
1749 Fixed argument passing with blanks in value for Windows Service.
1751 Disable YAZ' own log rotate by default (no 1 GB limit).
1752 The variable l_max_size which specifies the log file limit is set to 0
1753 (DISABLED): This is due to the fact that YAZ is most often deployed using
1754 logrotate. Also YAZ can not perform log rotate because of unsufficient
1755 permissions (setuid).
1757 --- 3.0.44 2009/02/17
1759 List supported encodings in man page for yaz-iconv.
1761 Fixed missing SSL libs for --libs output
1763 Re-established OID record syntax application-xml. Nobody should use it
1764 but we don't want to change soname because of this symbol being absent.
1766 --- 3.0.42 2009/02/02
1768 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1770 Added member named_result_sets for init handler struct for the GFS. This
1771 allows a server to disable named result sets.
1773 Removed OID record syntax application-xml.
1775 Added support for rule-based transliterator for ICU wrapper of YAZ.
1777 Fixed bug #1902: yaz-icu XML output.
1779 Make YAZ checks Emacs friendly.
1781 BITSTRING value shows value. Bug #2346.
1783 ISO2709 decoding: skip control characters from indicator data.
1785 Omit sort key by default in yaz-icu's output.
1787 Allow combined single char options (again) for YAZ' options function.
1789 Utility yaz-marcdump got option to display YAZ version (-V).
1791 Allow YAZ to use ICU 3.4.
1793 Added new ICU test case which illustrates removal of diacritics.
1795 --- 3.0.41 2008/12/29
1797 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1799 --- 3.0.40 2008/12/29
1801 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1804 Fixed bug #2352: yaz-marcdump crashes for certain record.
1806 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1808 Added support for Danmarc2 to UTF-8 conversion.
1810 Added support for ISO5426 to UTF-8 conversion.
1812 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1813 implementation version.
1815 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1817 --- 3.0.38 2008/11/10
1819 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1820 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1822 ZOOM C now interprets databaseName option for ZOOM connection as path
1825 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1827 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1829 Dummy Libxml2 types no longer defined in headers of YAZ'.
1831 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1834 --- 3.0.36 2008/09/26
1836 Various ODR chapter fixes.
1838 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1840 Added missing source for Windows compilation, mutex.c.
1842 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1844 For SRU connections in ZOOM all records up to "count" are now fetched.
1846 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1847 in Windows due to bad error handling for Libxml2.
1849 Added facility for sending arbitrary records (ASN.1 any) using
1850 ZOOM C's Extended service update. Patch by Sam Reynolds.
1852 New options for ZOOM C's connection, logapdu which makes ZOOM log
1855 --- 3.0.34 2008/06/18
1857 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1859 --- 3.0.32 2008/06/12
1861 Fixed memory violation that could occur when decoding UTF-8. This bug
1862 was only present in 3.0.30 of YAZ.
1864 --- 3.0.30 2008/06/06
1866 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1867 GNU TLS is used by default (if found).
1869 yaz-ztest returns OPAC records if a client asks for OPAC.
1871 Improved speed of MARC-8 encoding.
1873 Added support for lossy and loss-less MARC-8 encoding.
1875 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1877 Added new Windows Service wrapper (sc).
1879 yaz-client's itemorder command may now send a file.
1881 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1883 Added new function yaz_log_xml_errors.
1885 Allow (but warn) unknown XML attributes in MARCXML parsing.
1887 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1889 The UTF-8 to MARC-8 conversion now uses a different set of characters
1890 for Greek symbols. Bug #2120.
1892 --- 3.0.26 2008/02/21
1894 Added yaz_daemon (daemon.h).
1896 Fixed bug #2068: pkg-config trouble
1898 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1900 --- 3.0.24 2008/01/28
1902 Document --with-xml2 option.
1904 Added OPAC XML XSD (etc/opacxml.xsd).
1906 Allow glob mask for name attribute in retrieval element for the
1907 generic frontend server's retrieval facility.
1909 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1910 except POLLIN/POLLOUT.
1912 Fixed error handling in cs_listen. Bug #2037.
1914 --- 3.0.22 2008/01/20
1916 Fixed version in yaz/yaz-version.h.
1918 Fixed bug #2027: Crash when closing connection.
1920 Changed configure so that ICU support is only enabled if only ICU
1921 and Libxml2 is available (because the ICU chain is XML based).
1923 --- 3.0.20 2008/01/15
1925 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1926 is built. Only this DLL depends on the ICU runtime.
1928 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1929 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1931 Changed license of CCL module to 'Revised BSD'. After consultation with
1932 remaining members of the original EUROPAGATE consortium, we are re-issuing
1933 the CCL module without a separate license. The software was developed by
1934 Index Data as part of a research project. The special license was included
1935 to help feed usage information back to the project consortium to support
1936 project evaluation. At this time, the project consortium has long-since
1937 disbanded, and the majority of the original principals have retired. At the
1938 same time, we have significantly modified the software during the following
1939 years, to the point where very practically no original code remains. To
1940 simplify re-use of the software, we have contacted those members of the
1941 consortium who could be reached, and agreed to re-issue the module as a
1942 proper part of the YAZ package.
1944 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1946 CQL closer to being version 1.2 compliant. CQL also allows free-form
1947 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1950 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1951 bug could make Extended services handling crash in the ZOOM layer. This
1952 bug was only present in YAZ 3.0.18.
1954 --- 3.0.18 2007/12/19
1956 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1959 yaz-marcdump reads and writes collection wrapped records.
1961 Handle OPAC for record conversion module.
1963 Fixes for ICU wrapper.
1965 Allow ICU libs to be controlled with --with-icu .
1967 --- 3.0.16 2007/11/12
1969 Added yaz_poll which is a wrapper for select/poll. When poll is available
1970 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1971 sockets to be in use.
1973 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1974 functionality through an XML based configuration (ICU chain). This system
1975 is useful for search facilities such as Pazpar2 and Zebra that needs to
1976 perform tokenization of indexed material. The ICU code in a separate
1977 library libyaz3_icu.a.
1979 Added HTTP tunnel facility for COMSTACK, bug #1752.
1980 This is a facility that allows a Web proxy, such as squid, to tunnel
1981 Z39.50 traffic. This facility is "transparent" to must applications
1982 using YAZ. It's enabled by using pseudo transport connect: followed by
1983 the proxy address, followed by command, then follwed by he regular
1984 "virtual" addresss. For example,
1985 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1987 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1989 --- 3.0.14 2007/09/21
1991 Fixed bad memory reference in ZOOM_record - cuased by member not being
1992 initialized. This was a problem only in YAZ 3.0.12.
1994 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1995 fields were not removed.
1997 Changed the way C code is generated from codetables.xml. Made a MARC-8
1998 conversion trie for each characterSet section rather than codeTable.
1999 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
2000 of codetables.xml from Larry Dixson, LOC. Bug #1464.
2002 --- 3.0.12 2007/09/12
2004 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
2005 from ZOOM_record_error).
2007 ZOOM C function ZOOM_record_get returns record schema for type="schema".
2009 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
2011 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
2013 Better SRW-to-Bib-1 diagnostic mapping.
2015 ZOOM C and yaz-client announces SRU version 1.2 by default.
2017 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
2020 Fixed in yaz_sru_decode to allow other version than 1.1.
2022 --- 3.0.10 2007/08/22
2024 Added support for SRU scan for ZOOM.
2026 Added support for the use of the older versions or Extended Service
2027 Update in ZOOM. To faciliate this, an option "updateVersion" may be
2028 set to the version , 1=first, 2=second, 3=third. The third version is
2029 what ZOOM C has used so far. And that, obviously, is the default.
2031 Added support for CCL queries in Z39.50 queries sent to the GFS (and
2032 therefore in Zebra and in SimpleServer-based applications). The new
2033 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
2034 qualifier file used to transform incoming CCL queries into Type-1 RPN,
2035 which is passed into the back-end search callback function.
2037 Added support for HTTP Basic authentication in clients: the SRU/W
2038 codec encodes the username/password elements of the PDU structure
2039 appropriately, and these may be set using the "user" and "password"
2040 options in ZOOM-C applications (the same options that are used for
2041 Z39.50 authentication).
2043 --- 3.0.8 2007/06/25
2045 Fixed bug #1208: SSL appears to be broken in ZOOM.
2047 Fixed bug #1206: Libxml2 include path weirdness.
2049 Added oid_name_to_dotstring.
2051 Allow elementSetName to be specified for ZOOM C record update.
2053 Allow waitAction to be specified for ZOOM C based for Extended Services.
2055 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2056 syntax OID. Bug introduced in YAZ 3 series.
2058 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2060 --- 3.0.6 2007/06/06
2062 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2063 directory. yaz-client now reads commands from file given by option -f
2064 if specified; then tries to read .yazclientrc in current directory.
2065 Failing that, it reads .yazclientrc from user's home directory.
2067 Added support for correlationInfo Note and ID for Record Update via
2070 Added yaz-client command querycharset which specifies character set for
2071 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2072 (termListAndStartPoint).
2074 Charset ISO5428:1984 is an alias for ISO5428-1984.
2076 Implemented a way to perform scan in a result set using Z39.50. This
2077 is achieved by attaching the result set name in the characterInfo
2078 (type InternationalString) of OtherInformation in the Scan Request PDU.
2079 The result set is identified in the otherinformation by the new OID:
2080 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2081 This allows for scan in result set and faceted search . Zebra did some
2082 of this in the APT term using attribute type 8 and value being result
2083 set. Using the OtherInformation approach for this is cleaner and easier
2084 to work with in proxies and the like. This facility can be used in
2085 yaz-client using new command setscan which takes a result set as first
2086 argument, start position (APT) as second.
2088 Changed decoding of SRU XML packed records to deal with servers that
2089 have recordData with XML data with multiple root nodes. Also make
2090 comparison for recordPacking case insensitive. Again, one server
2091 returns "XML" where others return "xml".
2093 For SRU responses allow Content-Type application/xml as well as text/xml.
2095 --- 3.0.4 2007/05/21
2097 Fixed bug in character set conversion of BER strings. Bug introduced
2100 --- 3.0.2 2007/05/08
2102 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2104 For OID class, use oid_class consistently.
2106 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2109 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2110 character set for bibliographic information interchange". By Giannis Kosmas.
2112 Added documentation on new OID API.
2114 --- 3.0.0 2007/05/02
2116 Changes to generic frontend server interface: added new member
2117 'query_charset' for bend_initrequest structure. A backend init handler
2118 should set this member to its native character set for query terms.
2119 When defined, the frontend server logic will announce this character set
2120 to a client if the negotiationModel bit is set by the client. All server
2121 implementors are encouraged to specify this. If a backend server does not
2122 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2124 Added CCL utility to remove terms (stop words) from resulting RPN
2125 tree. This is handled by functions with prefix ccl_stop_words_ .
2127 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2128 terms in RPN queries.
2130 Clean-up the CCL API. Moved some internal structures from ccl.h to
2131 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2132 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2133 This is replaced by ccl_parser_find_str which takes a string instead.
2135 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2136 libyaz.la is the core of YAZ except the generic frontend server and
2137 does not depend on POSIX threads anymore. libyaz_server.la is the
2138 generic frontend server facilities and uses POSIX thread functionality
2139 if available. The libyaz.la no longer depends on POSIX threads because
2140 the number of global structures is limited. NMEM no longer re-uses blocks
2141 between threads ; it simply free's memory immediately but allocates in
2142 "large" chunks as usual. We don't expect any performance penalties
2143 because of this. The yaz_log system is still using a global log_level so
2144 caution must be taken when modifying it with yaz_log_init_.. +
2145 yaz_log_mask_str. This, however, should not cause any trouble because
2146 these functions are called during initialization of application code
2147 anyway. `yaz-config --libs server` returns libs for server applications;
2148 `yaz-config --libs` returns libs for non-server applications.
2150 New OID database - with public definitions in oid_db.h. Removed old OID
2151 database including the head oid.h and definitions such as enum oid_value
2152 and struct oident. The new OID database uses the same string names as
2153 before but the 'protocol' is gone. There are now only two representations
2154 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2155 converts from string to OID; functions with prefix yaz_oid_to_string
2156 converts the other way.
2158 Change to emit_term() in CQL-to-PQF query translation: when a term has
2159 the /regexp relation modifier, do not process it for leading and
2160 trailing "^" and "*", which have quite different meanings in regular
2163 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2164 write handlers no longer carries a 'last' parameter. This will make
2165 yaz_iconv flush "less" characters. A flush is performed by call to
2166 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2168 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2169 removed, because function yaz_query_to_wrbuf does the same.
2171 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2172 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2174 Deprecated MARC utility functions removed.
2176 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2179 Branch split: YAZ_2_1_55_branch
2181 --- 2.1.54 2007/03/16
2183 Fix to ZOOM-C so that transparent reconnection is properly handled on
2184 connections that are in asynchronous mode.
2186 Fixed compilation on OpenBSD 4.0.
2188 Large strings in GRS-1 records are now properly displayed in yaz-client.
2190 Added character conversion support for "advancegreek"; based on patch from
2193 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2194 sequence is met. Before the error was not set so it would be unknown.
2196 Adjust yaz-marcdump MARC reader so that it skips until record separator
2199 --- 2.1.52 2007/03/07
2201 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2202 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2203 fd_set structure used as a bitmask for the FDs to be selected on.
2205 Using ACX_PTHREAD macro to check for POSIX threads.
2207 Fixed have-vsnprintf check.
2209 --- 2.1.50 2007/02/23
2211 Fixes for configure on BSD. Bug #900.
2213 Added snprintf/vsnprintf wrappers for systems that don't have
2214 limits (heavens forbid).
2216 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2217 created before all previous tasks were completed and removed from the
2218 task queue, the new task could be removed by a mistake.
2220 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2222 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2224 Fixed bug #832: Problem with MARC/charset in yaz-client.
2226 Fixed bug #668: save command line history for yaz-client.
2228 Fixed bug #830: pkg-config support.
2230 --- 2.1.48 2007/01/23
2232 Extended ZOOM result set options with two options that may be read by
2233 a client: resultSetStatus and presentStatus with values as specified for
2235 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2237 Fixed bug #827: Using SSL fails on Debian etch.
2239 Fixed bug #826: Weird looking chars for set of MARC records.
2241 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2242 that is treated as an ItemOrder with itemRequest being an XML document
2243 external. The value of "doc" is the content.
2245 Extended the GFS search facility. New member of bend_search_rr
2246 'estimated_hit_count' signals that hits is known to be an estmate
2247 (higher or lower than real hit count). New member 'partial_resultset'
2248 signals that the search was partial (hit count is lower or equal than
2249 real hit count). For Z39.50, the information is stored in resultSetStatus
2250 member of SearchResponse APDU. For SRU, the information is signalled
2251 via SRU diagnostic 59: "Result set created with valid partial results
2254 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2256 --- 2.1.46 2007/01/13
2258 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2260 Added ZOOM_connection_peek_event.
2262 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2263 the following new functions:
2264 ZOOM_event_nonblock, ZOOM_connection_process,
2265 ZOOM_connection_get_{socket,mask,timeout},
2266 ZOOM_connection_fire_event_{timeout,socket}.
2267 The existing blocking event handler, ZOOM_event, is a wrapper for the
2268 + blocking ZOOM_event_sys_{poll,select}.
2270 Implemented function ccl_xml_config which parses XML version of CCL
2271 configuration (bug #798).
2273 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2275 Added timings utility (yaz/timing.h)
2277 --- 2.1.44 2007/01/03
2279 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2282 Fixed bug #779: Rotation of apdu.log fails.
2284 Fixed for character set conversions:
2285 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2286 Honor G1 set in MARC-8 decoding.
2288 --- 2.1.42 2006/12/17
2290 Fixed bug #775: char conversion does not handle Alternative UTF-8
2293 Implemented function yaz_marc_read_line which parses MARC line format
2294 records. There is a wealth of formats out there. So far, this function
2295 reads line records produced by yaz_marc_write_line.
2297 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2298 more generic and easier to remember(!) options: -i format and -o format
2299 which specifies input format and output format respectively - where
2300 format is one of "marc", "marcxml", "line", "marcxchange".
2302 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2303 does not print anything except warnings for records.
2305 For yaz-marcdump, added support for MARC split into files (-s) with a given
2308 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2309 spec, at http://www.loc.gov/standards/sru/record-update/
2310 This has changed the binary layout of the following structs:
2311 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2312 bend_update_rr . Patch by Ko van der Sloot.
2314 Added GFS utility function bend_assoc_is_alive which returns 1 if
2315 association is still alive (client is connected); 0 otherwise (client
2316 closed connection). This allows busy servers to stop working for
2319 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2320 been a separate piece of software. This version of ziffy has been modified
2321 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2323 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2325 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2326 Client code may now interrogate options such as "init_opt_sort" to
2327 find out whether the server claims to support various options.
2329 --- 2.1.40 2006/11/27
2331 Added utilities yaz_{set,get}_esn to set/get element set name from
2334 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2335 of YAZ and has been so since YAZ 2.1.10.
2337 Implemented ZOOM_record_error which returns error information for
2338 record (surrogate diagnostic).
2340 --- 2.1.38 2006/10/31
2342 Updates for SRU Update by Ko van der Sloot:
2343 1. Changed name from "operation" to "action"
2344 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2345 versions in the code, marked as 'backward compatible'.
2346 3. Added diagnostics for SRU Update.
2348 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2350 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2352 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2354 For GFS, fixed problem with SRU diagnostic 'First record position out of
2355 range' being issued for 0 hits.
2357 zoomtst10 part of Windows Build.
2359 --- 2.1.36 2006/10/13
2361 Implemented yaz_filepath_comp which splits a path into file path
2362 components (required by Zebra 2.0.3+).
2364 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2365 BSD inspired license until now so this should not have any real impact on
2366 anybody. See http://www.opensource.org/licenses/bsd-license.php
2368 Fixed bug #687: Missing log lines.
2370 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2373 Fixed bug #689: SRU diagnostics to be added.
2375 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2376 whether a connection is idle (no more work do do).
2378 --- 2.1.34 2006/10/04
2380 Change type of optval from long to int for invocation of setsockopt with
2381 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2383 Added support for specifying the max log file size for the Generic
2384 Frontend Server. The size is given with option -r.
2386 --- 2.1.32 2006/09/21
2388 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2390 --- 2.1.30 2006/09/17
2392 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2395 Fixed bug in Generic Frontend Server that could cause a server to stop
2396 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2398 For the generic frontend server, the maximum record size is used as maximum
2399 size of incoming packages (SRU + Z39.50). The value until was previously
2400 only used in Z39.50 Init negotiation and, later, in a session controlled
2401 sizes of records returned. This is controlled using -k option. It can be
2402 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2404 --- 2.1.28 2006/09/04
2406 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2409 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2411 New option for yaz-marcdump -lpos=value which allows setting a portion
2412 of MARC header to a certain value.
2414 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2416 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2417 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2419 --- 2.1.26 2006/08/15
2421 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2424 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2426 --- 2.1.24 2006/08/08
2428 Fixed MARC ISO2709 encoding routines to deal with character set
2431 Minor changes to GFS logging. Database included in search request log
2434 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2435 cached/multiple records.
2437 Shared libraries are built by default on Unix+configure.
2439 Changed cql2pqf transformation to use a different evaluation order. The
2440 new order is: always, relation, structure, position, truncation, index
2441 and relationModifier. Old order was: always, relation, relationModifier,
2442 structure, index, position, truncation. Note that the the latter ones
2443 override former ones for identical attributes.. The new scheme means that
2444 it is possible to override any existing attribute with a relationModifier.
2445 And also that it is possible to override everything for the index rule
2446 (except the ones listed in relationModifier). No order is perfect but this
2447 one, we believe, covers more real cases.. The "always" should have been
2448 called "default", since the attributes there can be overridden with all
2451 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2452 compilation phase, but also for yaz-config --cflags output. This allows
2453 us to have public headers with Libxml2 stuff in them . It should also,
2454 eventually, make Libxml2 checks redundant in packages using YAZ, such
2457 --- 2.1.22 2006/06/15
2459 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2460 stored in uri, message and details.. Previously diagnostics were stored
2461 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2462 compatibility.. but he's probably the only one affected, so.
2464 Added support for CCL, compiled on the client side, in ZOOM-C. This
2465 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2466 input; the resulting query objects can be used for for searching with
2467 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2469 YAZ' configure searches for OpenSSL by default.
2471 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2472 SL_CTX_use_certificate_file. See
2473 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2474 for more info. Thanks to Ko van der Sloot.
2476 --- 2.1.20 2006/06/02
2478 Bug #600: SRU GET, POST support for yaz-client. Introduced
2479 command 'sru' which selects method SOAP/GET/POST.
2481 Allow missingValueAction to be specified for the sortspec string -
2482 function yaz_sort_spec. By default, the missing value action is null.
2483 Use ! to specify "abort". Use = followed by stringvalue to specify default
2486 Ensured that Present-handler (if defined) is called in GFS before any call to
2487 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2488 searchRetrieve requests.
2490 Documentation for YAZ is now based on the Docbook XML/XSLT using
2491 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2492 is no longer depending on jade/openjade or docbook-to-man scripts.
2493 PDF is no longer part of the distribution - but can optionally be
2494 made using DSSSL/jadetex or FOP.
2496 Added retrieval handling support in Generic Frontend Server to support
2497 conversion between MARC/XML as well as XSLTtransforms. See
2498 etc/yazgfs.xml for an example.
2500 Added Authentication support to Generic Frontend Server in SRU
2501 mode. Authentication using HTTP Basic is supported, as is the use
2502 of 'x-username' and 'x-password' parameters in the request itself.
2504 Added support for a new character set MARC8s identical to MARC8 except
2505 that it converts combined characters to single Unicode characters in the
2506 Latin-1 range (when possible).
2508 --- 2.1.18 2006/04/24
2510 ASN.1 compiler 0.4: generates brief Doxygen file header for
2511 generated .h/.c files.
2513 Utility yaz_iconv now supports conversion to MARC-8.
2515 New facilities for the MARC module. The reading - and writing of
2516 content are separate methods for the yaz_marc_t handle. The following
2517 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2518 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2519 format). Write functions have prefix yaz_marc_write_.. The existing
2520 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2521 available. Removed support for OAI-MARC and simplexml (not the
2522 simplexml from PHP5).
2524 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2525 to be returned for this connection.
2527 --- 2.1.16 2006/03/31
2529 Allow multiple languages and charsets to be specified with
2530 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2531 negcharset iso-8859-1,utf-8
2533 Translation of proximity nodes from CQL into PQF now works.
2535 Moved to automake 1.8, 1.9.
2537 Added function yaz_log_set_handler which allows a log handler to be
2538 installed. This handler will be called for all log messages. Output
2539 to file is also produced; but that can be disabled by passing NULL
2540 fname to yaz_log_init_file.
2542 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2544 For SRW (including GFS), accept application/soap+xml as content-type
2547 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2548 produces NO stylesheet reference even if a default stylesheet is specified
2551 --- 2.1.14 2006/03/14
2553 Updated Windows package to include yazd.dll + yazd.lib for the
2554 Development component.
2556 If the environment variable YAZ_LOG is set, then it is used as a
2557 string indicating the default level of logging to use if not
2558 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2559 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2560 used as before. So, for example, to omit warnings from YAZ logging,
2561 export YAZ_LOG=-warn
2563 cql_transform() now map structure and other attributes before indexes,
2564 so that index-specific structures and other attributes can override
2565 defaults. So now a combination of mapping specifications such as:
2567 index.dc.date = 1=date-modified 4=5
2568 does the right thing.
2570 cql_transform() now also respects the "always" mapping specification,
2571 which establishes an initial set of attributes to be used for all
2572 terms except where overridden by more specific attributes associated
2573 with the index, relation or modifier.
2575 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2576 which mode to use; one of "post", "get" or "soap" (SRW, default).
2578 Fixes for yaz_iconv routines: changed trie-based character set conversions
2579 to use only non-negative values for bit fields due to Sun's C compiler not
2580 supporting negative values.
2582 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2583 sequences where not read correctly. Fix by Rustam Usmanov.
2585 Updated win/makefile to use options, settings which makes things
2586 compile with VS C 2005.
2588 --- 2.1.12 2006/02/01
2590 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2592 In ZOOM socket code, use select instead of poll on MacOSX.
2594 ZOOM-C now support client-side compilation of CQL into RPN that is
2595 sent to the server, enabling CQL to be used against all Z39.50
2596 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2597 ZOOM_query object, and submit it using ZOOM_connection_search().
2598 The CQL-to-RPN translation uses a configuration file, the name of
2599 which must be specified in the Connection's "cqlfile" option.
2601 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2602 function, which takes as its start-term parameter a ZOOM_query object
2603 (which may have had either CQL or RPN set into it).
2606 --- 2.1.10 2005/11/29
2608 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2609 GFS to support this as well. Backend handler, bend_srw_update, does the
2610 update work. Code contributed by Ko van der Sloot.
2612 Allow retrieval of Search Result-1 information in ZOOM by the use of
2613 options that are attached to a result set. ZOOM documentation updated
2616 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2617 UTF-8 conversion. Patch by Raj Patel.
2619 Added option -m to GFS to control formatting of timestamps in log file.
2621 Added 'exit' as synonym for 'quit' in yaz-client
2623 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2624 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2625 for the new members. Patch by Ko van der Sloot.
2627 Added support for SRU POST. It is supported for content-type
2628 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2630 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2631 Instead make the library libyaz.la multi-threaded. Threading as a whole
2632 can still be disabled by configure option --disable-threads. Previosly,
2633 with older GLIBCs there were problems with MT libs under Apache. This
2634 has now been fixed a long time ago.
2636 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2639 CQL module modified to be case insensitive for relations/indexes/operations.
2641 Fixed bug in CQL transform code: incorrect value relationModifieder
2644 Added 'show all' command for yaz-client which retrieves all results
2647 Added new yaz-client, xmles, which takes a (private) OID and
2648 a document to be sent as an extended service request.
2650 Describe new yaz-client commands wait_response and set_auto_wait.
2652 Increase TCP/IP listener backlog from 3 (which I am guessing was
2653 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2654 that the socket will queue as many incoming connections as it's able
2655 to handle ongoing connections. In other words, it will never now
2656 refuse a connection that it would be able to handle merely because
2657 it's not got around to accepting() enough of the pending connections
2658 yet. This is the behaviour anyway under Linux, where the listen()
2659 argument is ignored; but not under BSD and on systems such as
2660 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2661 YAZ-based servers should now be uniform across operating systems in
2664 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2665 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2666 This allows yaz-marcdump to read large MARC batches (>2 GB).
2668 Modified all YAZ source files - except the source which is auto-generated
2669 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2672 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2673 corresponding to the existing *_setl() function. These allow option
2674 values containing arbitrary valuues.
2676 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2677 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2678 except that it returns an indicator of whether or not the sort
2679 criterion was accepted (0 for OK, -1 for invalid).
2681 --- 2.1.8 2005/06/07
2683 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2684 MARC output rather than returning "new" buffer.
2686 yaz-client warns about unknown init options.
2688 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2690 --- 2.1.6 2005/05/24
2692 Added support for SRW sort in Generic Frontend Server. Patch
2693 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2694 sortKeys - or NULL if none is provided.
2696 Fixed bug #307: It was impossible to specify indefinite/no timeout
2697 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2700 Added support for multiple languages and charsets to be specified in
2701 ZOOM. Each charset/language is separated by a blank. If negotiation is
2702 in effect in init-response, Option
2703 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2704 Code based on patch by Vasiliy Osadchuk.
2706 Fixed bug #306: infinite recursion that occurred when calling
2707 yaz_log_level_init as the first call (before other log level or
2710 Fixed bug in scan handling in front end server: if preferred-Position-In-
2711 Response was non-present, a NULL pointer referece was performed.
2713 --- 2.1.4 2005/04/26
2715 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2716 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2717 now defined for all those error codes. So instead of putting 109 in
2718 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2719 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2721 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2724 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2726 Program yaz-client now exits and produces an error message if multiple
2727 Z39.50 servers are specified on the command line (none or one allowed
2730 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2733 --- 2.1.2 2005/03/16
2735 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2737 Fixed bug #272: Preserve spacing for CCL terms.
2739 --- 2.1.0 2005/03/14
2741 Added support for virtual hosts and multiple backend servers for
2742 the YAZ frontend server. The configution is XML based and
2743 support specificition of CQL to RPN mappings and explain information.
2744 See section "Virtual Hosts" in the YAZ manual.
2746 Extended OPAC display utility. OPAC display utility renders
2747 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2748 to supplement yaz_marc_decode_wrbuf.
2750 Fixed a bug in MARC decoder that could caused it to crash for some
2751 invalid MARC records. More diagnostics and warnings where added in
2752 XML output (warnings, etc are stored in comments).
2754 --- 2.0.34 2005/02/08
2756 Fixes for UNIX domain sockets. Bug #261.
2758 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2760 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2761 Added yaz_marc_subfield_str which defines subfield lead string which is
2762 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2763 yaz_marc_endline_str which defines end of fields string used in
2764 YAZ_MARC_LINE format. Default string is newline.
2766 Experimental support for MarcXChange. This format can be produced
2767 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2768 http://www.bs.dk/standards/MarcXchange.xsd
2770 Added yaz-client commands scansize that sets maximum number of
2771 entries to be returned by scan.
2773 --- 2.0.32 2005/01/11
2775 Added support for SRW scan in yaz-client and Generic Frontend Server.
2777 * Added whereInList member to SRW Scan Term.
2779 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2781 Fixed NMEM system to return aligned blocks on the smallest boundaries
2782 that are suitably aligned for all possible types on the particular
2783 architecture YAZ is being built for.
2785 --- 2.0.30 2005/01/04
2787 Fixed numerious warnings that was issued with newer versions of GCC.
2789 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2790 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2793 Make YAZ Generic Frontend Server slightly faster.
2795 Enhance (and reduce) logging for Generic Frontend Server.
2797 Revert YAZ log system so that it flushes every write operation
2798 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2800 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2801 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2802 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2803 will effectively disable old definitions.
2805 --- 2.0.28 2004/11/09
2807 Added yaz_log_time_format which specifies log format using
2810 Added yaz_log_module_level which returns mask for a module. Value
2811 is non-zero mask a if module is enabled; zero if disabled.
2813 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2814 in include/yaz/cql.h.
2816 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2818 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2820 Fixed bug #172: RPM builds does not enable SSL.
2822 Doxyfile.in part of dist. Doxyfile generated by configure.
2824 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2825 are given and the corresponding component does not exist.
2827 Extend CCL documentation in YAZ reference. Describe r=r.
2829 --- 2.0.26 2004/10/01
2831 Fixed MARC->MARCXML conversion to properly deal with
2832 fields, subfields, indicators having non-ASCII characters.
2834 Fixed MARC->MARCXML conversion so that ASCII control characters
2835 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2838 Added YAZ GFS support for conversion from Z39.50 surrogate
2839 diagnostics to SRW surrogate diagnostics.
2841 Bug fix: YAZ GFS did not return schema in explainResponse.
2843 --- 2.0.25 2004/09/30
2845 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2846 now converts recordSchema to elementSetName as well as schema URI.
2848 Fixed bug in COMSTACK that prevented HTTP request packages from being
2851 --- 2.0.24 2004/09/29
2853 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2854 does not require white-space before and after the dash in a range, e.g.
2855 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2858 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2859 due to new GCC removing "redundant" code.
2861 Added yaz-client commands scanpos and scanstep that sets preferred
2862 position and step-size for scan.
2864 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2866 Added CCL utility ccl_qual_buf which parses one or more CCL
2867 spec lines in a buffer.
2869 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2870 of name and value - ignoring empty lines and comments.
2872 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2874 Added odr_get_element_path which returns current element path for an
2875 ODR handle. This utility is useful in error handling or user-defined
2878 Added ODR_PRINT utility odr_set_stream which is is a more generic
2879 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2880 to a write function and pointer to close function. The close function - if
2881 non-NULL - will be called during odr_destroy.
2883 Fixed bug in CCL parser where truncation char was not removed from
2884 right side when truncation=both was in effect.
2886 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2889 --- 2.0.23 2004/08/11
2891 Fix buffer overrun in CQL parser when dealing with proximity (%).
2893 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2894 to UTF-8/UCS conversion is now only based on codetables.xml.
2896 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2898 --- 2.0.22 2004/08/06
2900 Add support for more "commit changes" in ZOOM (uses Extended Services).
2902 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2905 Yet another small fix for configure of SSL.
2907 --- 2.0.21 2004/05/14
2909 Fix SSL libs for configure when --with-openssl=DIR is given.
2911 --- 2.0.20 2004/05/10
2913 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2915 SSL comstack now uses yaz.pem certificate file on server side
2916 by default. Certificate filename can be configured by calling
2917 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2919 Fix bug regarding multiple calls to ZOOM_connection_connect.
2921 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2923 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2924 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2926 ZOOM now allows inspection of X509 peer certificate for verification.
2927 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2929 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2930 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2931 as "modular" but it simplifies things.
2933 Added cs_get_peer_certificate to that returns peer X509 PEM.
2935 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2936 NULL if SSL is unavailable.
2938 Documentation about MARC decoding tools.
2940 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2942 --- 2.0.19 2004/03/30
2944 Rename CHANGELOG to NEWS to follow GNU style packing.
2946 Fix bug with missing initialization of member in init_diagnostics.
2947 This bug affects threaded version of GFS server.
2949 --- 2.0.18 2004/03/20
2951 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2954 Ensure zlib.dll is packed with Windows install.
2956 --- 2.0.17 2004/03/17
2958 Fix encoding of xsd:string to use text instead of CDATA.
2960 Fix endless loop in CQL parser with unbalanced ".
2962 Use a more compact way to store MARC-8 conversion tables.
2964 --- 2.0.16 2004/03/16 Debian only
2966 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2969 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2974 --- 2.0.15 2004/03/01
2976 Another fix for decoding of XML packed records.
2978 --- 2.0.14 2004/02/25
2980 Fixes for Chunked encoding. White space not ignored after length spec.
2982 Update NS and use default NS for SRW diagnostic elements.
2984 --- 2.0.13 2004/02/23
2986 Implement ZOOM_resultset_cache_reset which resets record cache.
2988 Implement ZOOM_resultset_sort which sorts a result set.
2990 Implement chunked HTTP transfer.
2992 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2994 --- 2.0.12 2004/02/16
2996 Added member 'schema' to bend_explain_rr structure so that backend
2997 can specify explain record identifier. Defaults to Zeerex 2.0.
2999 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
3001 --- 2.0.11 2004/02/16
3003 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
3006 Added init command for yaz-client which sends "extra" init request.
3008 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
3009 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
3011 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
3013 Make ZOOM error code for "invalid query".
3015 Fixed compilation for SSL which wasn't properly enabled for all platforms.
3017 --- 2.0.10 2004/02/05
3019 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
3022 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
3024 Added option -p <file> to make Generic Frontend Server to write PID file.
3026 Added option -D to put Generic Frontend Server in background on its own.
3028 Make ZOOM C recognize option "password". If unset, "pass" is used
3029 (for backwards compatibility).
3031 Fixed a bug in Generic Frontend Server that could make it crash if a
3032 client sets characterSetNegotation bit, but didn't pass negotiation stuff
3035 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
3036 Must be issued before open, in order to be in effect.
3038 --- 2.0.9-6 2004/01/12 Debian/Windows
3040 Make the SRU server more picky WRT unknown params, etc.
3042 Bug fix: ZOOM scan response didn't return displayTerm - when present.
3044 New YAZ client command, options, that sets Z39.50 options.
3046 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3047 options from a string of tokens (one token for each option bit).
3049 Update SRW diagnostic code messages.
3051 --- 2.0.9-5 2004/01/07 Debian/Windows
3053 Handle user defined stylesheet for SRW/SRU.
3055 --- 2.0.9-4 2004/01/06 Debian/Windows
3057 Fix bug in decoding of Content-Length.
3059 --- 2.0.9-3 2004/01/06 Debian/Windows
3061 Fix a bug with decoding of XML packed records.
3063 --- 2.0.9-2 2004/01/05 Debian only
3065 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3067 Fix bug in SRW/SRU diagnostics decoding.
3069 --- 2.0.9 2004/01/05
3071 Fixed bug in Generic Frontend Server which could drop records exceeding
3072 preferred message size. Reported and fixed by Irina Dijour.
3074 Fixed calculation of package size for structured records in Generic
3075 Frontend Server. Reported and fixed by Irina Dijour.
3077 Fixed namespace for SRW/SRU diagnostics.
3079 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3081 --- 2.0.8 2003/12/22
3083 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3084 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3087 CQL changes to reflect recent changes to the specification:
3088 * Documentation talks about context sets instead of index sets.
3089 * Documentation talks about indexes instead of qualifiers.
3090 * The CQL-to-PQF transformer's configuration file now uses
3091 "index.set.name = <attributes>" instead of the old form
3092 "qualifier.set.name = <attributes>". (Both forms are still
3093 understood but the latter is deprecated.)
3094 * CQL terms with no explicit index specified are now interpreted as
3095 cql.serverChoice instead of srw.serverChoice (which of course
3096 behaves exactly the same.)
3098 --- 2.0.7 2003/12/16
3100 MARC conversion can now generate ISO2709 output in another
3101 character set. yaz-marcdump uses this facility if you invoke it
3104 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3105 functions from there can be used from C++.
3107 --- 2.0.6 2003/12/04
3109 Frontend server now transfers memory from decoded packages to stream
3112 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3113 references to show up.
3115 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3116 the ZOOM Abstract API. The older names for the same options are still
3117 also supported for the benefit of old applications.
3119 ZOOM-C supports "implementationId" and "implementationVersion" options
3120 to go along with "implementationName". These allow the user code to
3121 specify identification strings to be sent to servers.
3122 Add OID for the new ExtLite attribute set.
3124 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3125 as requested/supplid by Ere Maijala <ere@atp.fi>
3127 For generic frontend server, reverse the order of
3128 "toolkit-supplied / application-supplied" strings sent as implementationId,
3129 Name and Version. Also, remove the spaces around the slash. This brings
3130 the GFS in line with the behaviour of ZOOM-C on the client side.
3132 Add function ZOOM_scanset_display_term.
3134 yaz-client shows scan displayTerm if present.
3136 Utility yaz-iconv is now installed by default along with the man page
3139 Extend configure check for OpenSSL to use pkg-config where available (such
3142 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3143 server to specify uid/gid/mask for socket using the format
3144 unix:[user=uid,][group=gid,][umask=mask,]file=path
3145 If file= is omitted the existing format is assumed, e.g.
3147 in which case the mask is 0666 (rw for everybody).
3149 Major restructure of YAZ source. All source in libyaz is in src directory.
3150 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3151 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3153 Added man page for utility yaz-marcdump (used to be called marcdump).
3154 yaz-marcdump is installed by 'make install'.
3156 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3157 of incoming package failed.
3159 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3161 Change prototype of odr_perror: add const to message string.
3163 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3165 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3166 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3167 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3168 DNS lookup. There should not be any compatibility problems with this
3169 assuming that blocking=1 or 0 is used.
3171 Fix bad reference in UNIX comstack in function cs_addrstr.
3173 Fix for compilation on AIX.
3175 The generic front-end server (server/seshigh.c) now supports returning
3176 Init diagnostics to the client in User-information-field, in
3177 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3180 --- 2.0.4 2003/09/04
3182 Allow any CQL relation (not just all,any,exact,scr).
3184 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3185 that features the same UI.
3187 Implemented command update0 in YAZ client which is equivalent to
3188 update but uses old of Ext Update ASN.1.
3190 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3191 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3192 Previously no OID was used for this info.
3194 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3195 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3196 returns 'malformed search term' otherwise.
3198 SortResponse member resultCount now set to NULL in sort handler of
3201 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3204 Add three new utility functions for translating OIDs between various
3205 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3206 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3207 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3208 char *oid_to_dotstring(const int *oid, char *oidbuf);
3209 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3211 Reverted modifications for ES Update definition for z_IU0Update
3212 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3213 is back to YAZ 2.0.2.
3215 String value attributes for CCL parser.
3217 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3218 which their FirstSearch server returns in Init responses, sometimes
3219 carrying useful diagnostic information when Init fails. This has the
3220 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3221 "z39.50/oclcui.asn", where its definition is somewhat different from
3222 what OCLC document on their web-site, as required to interoperate with
3225 Support for anonymous authentication in yaz-client. Use the command
3228 * Fix the OID of the Index Data-local "admin" Extended Service from
3229 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3230 the 1000, which indicates a locally-defined OID, was a mistake.
3232 --- 2.0.3 2003/06/20
3234 Fix CCL directive @case handling so that it affects string match for
3235 both CCL keywords and qualifiers.
3237 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3238 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3239 Decoder has been updated with ASN.1 changes as listed in
3240 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3241 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3242 z_IUUpdate, remains unchanged.
3244 ZOOM_record_get may now return a record in a specific character set.
3245 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3246 "from" is the character set of record as returned by target. "to" is
3247 the character set to be returned. If omitted, "to" is UTF-8.
3249 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3251 New ODR utility, odr_getelement, which returns name of element for
3252 which encoding/decoding failed.
3254 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3255 in cases where a required element was omitted.
3257 Bug fix: some MARC8 sequences were not converted.
3259 New ZOOM option "step" which specifies number of records to be
3260 retrieved in one chunk. Used in conjunction with "start" and "count".
3262 SRW support for yaz-client. Use scheme http: to use it, e.g.
3265 yaz-client no longer does (un)intelligent character set conversions
3266 by default. Can be enabled with charset and marc_charset commands.
3268 xmalloc trace fix for 64-bit systems such as DEC alpha.
3270 Solaris 2.6 compile fix.
3272 New function, cql_strerror() translates SRW error codes, as returned
3273 by cql_transform_error(), into human-readable English strings. Used
3274 in yaz-client diagnostics when appropriate.
3276 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3277 converts it into a type-1 query which is sent to the server. This
3278 makes CQL available for use with all Z-servers, as opposed to the tiny
3279 minority that can handle CQL queries themselves.
3281 --- 2.0.2 2003/04/28
3283 New Debian package layout similar to the Redhat Package layout.
3285 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3286 and search result respectively.
3288 --- 2.0.1 2003/04/25
3290 Redhat package is now several packages: libyaz (runtime libraries),
3291 libyaz-devel (development and documentation, and yaz (utility programs).
3292 Package spec file by Morten Bogeskov.
3294 New member 'schema' in struct bend_fetch_rr which the name of requested
3295 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3296 handler MAY set this to reflect the schema of the returned record.
3298 New member 'display_term' in struct scan_entry. GFS now sets member entries
3299 and allocates scan entries to be filled by user scan handler. In previous
3300 version, entries member was allocated by the scan handler. That still works,
3301 but the GFS will ignore member display_term - assuming it was NOT set by
3302 the handler. The fact that the GFS now allocates the entries both allows
3303 for new members and makes a scan handler easier to write.
3305 Fix CQL lex buffer overflow.
3307 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3308 SRU default recordPacking is string.
3310 SRU protocol support for frontend server.
3312 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3314 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3316 Added scan for the ZOOM shell (zoomsh).
3320 * String Identifers for Schemas (Amendment 5).
3321 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3322 Old definition for schema
3323 Odr_oid *schema; /* OPT */
3328 Z_InternationalString *uri;
3329 #define Z_Schema_oid 1
3330 #define Z_Schema_uri 2
3333 * resultCount parameter to Sort Response (Amendment 1).
3334 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3336 Support for SRW 1.0 over HTTP. This is an optional feature and
3337 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3340 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3341 on the same port. SRW SearchRetrieveRequests are mapped
3342 to bend_init,bend_search,bend_fetch,bend_close.
3344 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3346 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3347 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3349 ZOOM connections are SRW based if schem http is used for hostname
3350 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3351 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3353 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3354 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3355 distance=n, order=true/false, relation=le, prox unit=word. If
3356 n is omitted, distance 1 is used.
3358 Fixed problem with C compiler include path in wrong order.
3360 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3361 on Solaris. Patch from Ko van der Sloot.
3363 New MARC decode API. All new functions operate on a yaz_marc_t
3364 handle. The most important new functions are: yaz_marc_create,
3365 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3366 decode and destroy respectively. Decoder can produce formats
3367 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3368 include/yaz/marcdisp.h.
3370 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3371 to UTF-8, UCS-32, wchar_t or Latin-1.
3373 * Prototypes for yaz_iconv_-functions moved to separate header
3374 include/yaz/yaz-iconv.h.
3376 Make a few private functions 'static' in unix.c. This prevents
3377 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3379 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3380 are set when Init Response is received.
3382 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3383 but returns diagnostic set as well.
3385 New function yaz_strerror which is a portable wrapper for
3386 strerror/strerror_r/GetLastMessage.
3388 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3389 is returned for MARC. If type is "oai", then OAI MARC is returned.
3391 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3394 --- 1.9.2 2002/11/26
3396 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3398 Fix bad race conditions on SIGTERM and terminate gracefully in
3401 Move retrieval (data1) module to Zebra since nobody seems to be
3404 Add GRS-1 render for ZOOM using same format as yaz-client.
3406 --- 1.9.1 2002/10/05
3408 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3410 Fix broken ESpec handling in data1 module.
3412 SGML reader parses comments and makes them part of the data1 tree.
3414 Added several type casts so that YAZ compiles as C++ code.
3416 ZOOM didn't handle PDU encoding failures properly.
3418 Added more Bib-1 diagnostics (approved extensions).
3420 GNU configure: better check for iconv.
3422 More portable use of accept, getpeername. Check for socklen_t. Use
3423 int/size_t if socklen_t is not defined.
3427 PQF parser rejects bad queries - including those with extra
3428 characters in them. PQF parser used to silently ignore that.
3429 Cleaner API for PQF added, which allows you to get detailed
3430 error information for bad queries (see yaz/pquery.h).
3432 Fixed bug in ZOOM_record_get for type "database".
3434 Implemented mini iconv library supporting conversions between
3435 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3437 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3439 --- 1.8.9 2002/08/20
3441 Fixed ZOOM C record cache so that preferredRecordSyntax and
3442 elementSetName is used to check for already fetched records.
3444 --- 1.8.8 2002/08/02
3446 Added three members in bend_initrequest structure to facilitate
3447 character set negotiation.
3449 Fixed a bug in frontend server that could cause indefinite
3450 loops under rare conditions.
3452 Revised character set utilities (charneg.h) so that encoding
3453 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3455 For PQF, directive @term <type> sets term type for Scan/Search.
3456 Here <type> is general, string, numeric, null. The term type
3457 is inherited - just like @attr.
3459 New call odr_set_charset that sets character set conversion for
3460 international-strings on a ODR stream. Prototype is:
3461 int odr_set_charset(ODR o, const char *to, const char *from);
3462 The InternationalString is still represented as C string in YAZ
3463 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3464 won't). On the protocol level, you can use any encoding.
3466 Support for UNIX sockets in ZOOM.
3468 Solaris recv sometimes returns errno == ENOENT. It is treated as
3469 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3471 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3472 both client and server. Code by Morten Bogeskov.
3474 --- 1.8.7 2002/05/22
3476 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3477 that they can be used directly from Visual Basic. You must recompile
3478 your windows APP if you're using ZOOM.
3480 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3481 Commands "lang" and "charset" sets language and character set respectively.
3482 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3483 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3485 Attributes from multiple CCL fields may be OR'ed rather than merged
3486 using directive "@field or". Fields are still merged by default -
3487 equivalent to "@field merge".
3489 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3492 Fixed bug in zget for parameter ExtendedServicesResponse.
3496 --- 1.8.6 2002/03/25
3498 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3500 Client displays USR.1:SearchResult-1 (hits per term).
3502 Additional Search Info for search in Generic Frontend Server.
3504 Fixed CCL parsing of "field=s".
3506 WIN32 installer - using the excellent NSIS software from nullsoft.
3508 Fixed CCL parsing of "field = - <number>".
3510 Added function yaz_marc_decode that decodes MARC for line mode
3511 display or XML (similar to that used by JZKit).
3513 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3514 Z39.50. But ISO/ILL was, however.
3516 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3517 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3519 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3520 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3522 --- 1.8.5 2002/02/03
3524 New YAZ client features: Command completion and new commands:
3525 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3526 Code provided by Jacob Poulsen.
3528 New call oid_trav, that visits all registered OIDs via callback.
3530 Function ZOOM_record_get now returns const char pointer rather than
3531 void pointer. It saves a lot of type casts.
3533 For YAZ client, command "auth" now allows you to set authentication
3534 in IdPass style. It is enabled when three tokens are given - order
3535 is user, group and password.
3537 Fix memory leaks in MARC record handling for ZOOM.
3539 New option for YAZ client, -k <kilobytes> that sets
3540 maximum record size. Similar to -k option for generic frontend
3541 server and yaz-ztest.
3543 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3545 Prefix query parser reports "fail" when bad attribute set is given.
3547 Fix in MARC decoder. Proximity logging. Fix for attribute set
3548 in scan handler for server. Patches by Shigeru Ishida.
3550 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3553 Configure option --with-openssl=<dir> now works when a directory is
3554 specified. Patch provided by Morten Bogeskov.
3556 New option for YAZ client, -u <auth>, that sets authentication.
3558 ZOOM fix: error information was sometimes "missing", since error
3559 was cleared/reset too when it shouldn't.
3561 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3563 --- 1.8.4 2002/01/04
3565 Scan for ZOOM API. New object ZOOM_scanset. New functions
3566 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3567 ZOOM_scanset_destroy.
3569 New ZOOM function, ZOOM_connection_last_event, that returns type
3570 of last event (such as "receive data", "send data", "apdu received",
3573 New ZOOM option, schema, that specifies schema for retrieval.
3575 New CCL feature. Qualifiers can be aliases for one or more
3576 other qualifiers (if more than one is given, OR is used).
3578 ZOOM uses named result sets if target supports it.
3580 Two new YAZ client commands: . (dot, which sources a script of YAZ
3581 client commands), and ! (to execute shell command.). Implemented
3584 Working on Debian packages.
3586 --- 1.8.3 2001/11/19
3588 YAZ client enables named result sets only if target supports it.
3590 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3592 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3593 with key="host" to get same result.
3595 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3596 Function Z3950_resultset_record(s) returns references to records
3597 "owned" by resultset. To become owner use Z3950_record_clone.
3599 Function z_ext_record handles Extended Services. Thanks to
3602 --- 1.8.2 2001/11/12
3604 CCL Parser fix: ignore token comma when dealing with and-lists.
3606 Documentation updates for COMSTACK.
3608 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3609 Changed prototype Z3950_records. For some functions, int parameters
3610 were changed to size_t.
3612 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3615 New MARC decode/display function, marc_display_exl, which properly rejects
3616 non-ISO2709 records. YAZ client uses it.
3618 --- 1.8.1 2001/10/29
3620 Fix bug: local attribute set wasn't set correctly in PQF strings.
3624 * Old Z39.50 codecs no longer supported.
3626 Added ZOOM C binding. See http://zoom.z3950.org/
3628 Renamed states for COMSTACKs to avoid confusion with events.
3630 Implemented cs_look and proper cs_rcvconnect.
3632 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3634 Configure detects POSIX threads on OpenBSD.
3636 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3637 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3639 When error is returned from present handler, non-surrogate diagnostic
3640 is returned in present response (and fetch handler is no longer called).
3642 * Minor adjustments to pquery parser (PQF). Token characters may be
3643 escaped by using backslash (C-style).
3645 PQF parser allows string attribute values to be specified. For @attr,
3646 non-numeric characters after the equal-sign are treated as strings
3647 (e.g. @attr 9=title).
3649 CCL trunction character may be defined (@truncation in file)
3651 * function zget_ExtendedServicesRequest sets waitAction to
3652 waitIfPossible (was wait).
3654 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3657 CCL operator names may be set in field definition files (CCL_bibset).
3658 See ccl/bib1 for an example.
3660 Fixes in ASN.1 compiler for C++ compatibility.
3662 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3663 and "op_or" to avoid conflict with C++.
3665 Fixed problem with GNU readline detection on Redhat 7.0.
3667 Added step-size for Scan backend handler.
3669 Fixed bug that made the frontend server crash when no attribute
3670 set was specified for scan.
3672 Front-end server automatically switches to original working directory
3673 when installed as an NT service. Previously -w had to be specified to
3676 Added extended attributes for retrieval module (data1), so that data1
3677 records carry d1_readXML/SGML attributes. d1_read also supports
3678 null-data rules ( <tag/>)
3680 On UNIX when POSIX threads are available, a separate library libyazthread
3681 is created. Programmers should link with that library and the yaz library
3682 when using threads. The reason for the split was that some applications
3683 on Linux, such as Apache, doesn't work well when using shared objects that
3686 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3687 (or any frontend server) in SSL mode by specifying ssl: followed by
3688 address. Only tested on UNIX.
3690 Added feature for CCL module. Virtual structure s=al or s=ol generates
3691 and-list and or-list respectively instead of phrase search.
3695 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3696 log_mask_str. This was done to avoid name conflicts with other libraries
3697 (such as other PHP extensions).
3699 Added raw OID member for preferred record syntax (request_format_raw)
3700 and returned record syntax (output_format_raw) for backend fetch method.
3702 Config file yaz-config now accepts options so that it returns specific
3703 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3705 Shared library support for UNIX using GNU libtool.
3707 * Modified backend interface. Request/Response struct's replaced by
3708 one read/write C struct. For example bend_fetchrequest and
3709 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3710 Every handler - even search has to be registered in bend_init
3711 handler. This means that the YAZ library no longer refers to
3712 external functions and it makes it possible to make the whole
3713 thing a single DLL/SO.
3715 Added Segment handler for backend server.
3717 Added Zmbol/Zebra administrative functions to YAZ client.
3719 Threaded frontend server on UNIX (when POSIX Threads are available).
3720 Starting the server with option -T enables multi-threading.
3724 Added configure option --enable-comp/disable-comp to control use
3725 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3726 located in sub directory asn.
3728 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3729 in ${exec_prefix}/bin along with the other programs yaz-client and
3732 GNU automake used to maintain makefiles.
3734 Added several OID's.
3736 Changed retrieval module so that we can load records with no abstract
3737 syntax defined. Tagpaths in these records are fully composed of string
3740 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3744 On UNIX, the generated makefile now supports a proper 'make install'.
3745 The prefix can be set via GNU configure to set the install location
3746 (default is /usr/local).
3748 * YAZ programs client and ztest were renamed to yaz-client and
3749 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3750 locations, such as /usr/bin,/usr/local/bin,etc.
3752 * YAZ Header files were moved from include to include/yaz. YAZ Header
3753 files are referred to as include <yaz/log.h> rather than <log.h>.
3754 The YAZ include path (-I ..) is therefore the same as before. Programmers
3755 should update their #include statements or use -Ipath/include/yaz
3756 instead. The main motivation for doing this change is that YAZ header files
3757 can be installed in "standard" locations /usr/include,/usr/local/include
3758 without introducing conflicts, since ALL YAZ header files are stored
3759 in subdirectory yaz (under /usr/include for example).
3761 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3762 rather than project/workspace files. We switched because project files
3763 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3766 Changed name of logging function, logf, to yaz_log, to prevent name
3767 clash with some math-log functions. The YAZ header log.h defines logf
3768 to yaz_log (#define) so there should be no incompatibilities by this
3771 Added bend_start/bend_stop handlers for server. These handler are
3772 called on start/stop of server. For windows they are called whenever
3773 a service is started/stopped.
3775 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3776 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3777 in util/yc.tcl. The auto-generated C code structures are, in a few
3778 cases, incompatible with the old decoders. There are differences in the
3779 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3780 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3781 The preprocessor variable ASN_COMPILED is defined when the compiled
3782 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3783 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3784 wish to use the old encoders/decoders you can specify --disable-yc
3787 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3788 version so that it supports both new - and old version of DB Update
3790 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3791 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3792 change. The name parameter can be set to 0 in which no name is specified
3793 for the construction. The macros odr_implicit and odr_explicit sets name
3794 parameter to zero for the construction involved. New macros
3795 odr_implicit_tag and odr_explicit_tag are similar to the others,
3796 except that a name parameter is added. For programmers' that don't use
3797 ODR they probably only need to change the call to z_APDU and z_External.
3799 Added access control facility by interfacing the TCP wrapper library.
3800 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3801 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3802 name of the daemon and enables the access control as specified in
3803 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3805 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3806 den Dool <H.M.vdnDool@kub.nl>.
3808 Added reference ID parameter to most functions in server API - refer
3809 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3811 Changed name of ccl library to libccl.a (was ccl.a).
3813 Fixed bug in decoder for Explain (Category TargetInfo).
3815 Added support for GNU readline in client. Thanks to Jacob Poulsen
3816 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3818 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3819 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3820 IMPLEMENTATION! This change was made to the development version before
3821 the ZIG decided to retract the amendment. If any users MUST be
3822 compatible with the original Update definition, PLEASE CONTACT US, and
3823 we will include a separate definition corresponding to the old Update
3824 ES. Note that because of the change to the ASN.1 of the
3825 TaskPackageRecordStructure we cannot define a single structure that
3826 will support both versions.
3828 * Added const modifier to buffer parameter for some ODR/BER encoding
3829 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3830 completeWAIS, odr_dumpBER.
3832 Fixed bug in client.c which caused a crash when a scanResponse didn't
3833 contain positionOfTerm.
3835 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3836 * will cause an error in a client if a non-YAZ target sends both a
3837 * list of Scan entries and non-surrogate diagnostics.
3839 Retrieval module enhancements. Tag sets may be typed in the reference
3840 to it. From the .abs-file the "tagset" directive takes a third optional
3841 integer type for the tag set referenced. From a .tag-file the "include"
3842 directive takes a third optional type as well. The old "type" directive
3843 in the tag set itself is still recognized but acts as the default type
3846 Backend interface change. Individual Scan terms returned from bend_scan
3847 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3848 in include/backend.h.
3850 Retrieval module enhancements. Multiple tag sets and attribute sets may
3851 be specified in abstract syntax specs. Revised the error/warning for
3852 logging messages reported by the retrieval module when reading the
3855 Object Identifier system (oid_..) changed. The API is backwards
3856 compatible but the oid-routines now allocates new OID's when needed.
3857 Raw OID's may be specified in oid_getvalbyname.
3859 YAZ now uses GNU configure to generate Makefile(s).
3861 * Minor changes in some of the member names of DeleteResultSetRequest and
3862 DeleteResultSetResponse. See include/proto.h.
3864 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3865 and added member 'languages' in TargetInfo (which was missing).
3867 Changed the way attribute sets are handled in the retrieval
3868 module. These are now cached, just like the abstract syntaxes
3871 Changed YAZ so that it links with compiled ASN.1.
3873 Added Explain-schema definitions and mapping routines. The following
3874 Explain categories have been implemented: AttributeDetails,
3875 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3877 Fixed minor bug in Windows version of Server Library.
3879 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3881 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3883 Added EXTERNAL: UNIverse Resource Report (non-standard).
3885 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3886 ENUMERATED and SET OF.
3888 * Added 'const' to some of the char pointer arguments for the
3889 functions, data1_read_node, data1_getelementbytagname,
3890 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3893 Fixed bug in data1_insert_taggeddata - the last_child member of
3894 parent wasn't initialised.
3896 * Changed data1_read_record and data1_read_node so that the supplied
3897 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3898 doesn't refer to any parts of the "SGML"-buffer.
3900 Fixed bug in server library (Windows version of statserv_remove).
3902 * Changed code so that it compiles as C++. The type definition
3903 of Odr_fun which is a member of Odr_arm was changed. The result is,
3904 that an explicit typecast is needed for the fun pointer when
3905 using Odr_arm - as in:
3906 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3908 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3910 Implemented the new structured date and time definition as approved
3911 by the ZIG. Added schemaId element to the specificTag in Espec-1
3912 (also approved at the last ZIG). Thanks to RVDM.
3914 Added some Object identifiers (RVDM).
3916 Changed the Update Extended Service (RVDM).
3918 Added command "refid" to client which specifies referenceId for
3919 the following requests.
3921 Implemented extended service handling for server. See ztest.c
3922 for an example as well as backend.h. New handlers are registerd
3923 in the Init handler.
3925 * Changed interface for sort in server.
3927 Added new members to statserv_options_block. It allows a server
3928 to read options from another source than just the command line. Thanks
3929 to Charles Woodfield.
3931 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3932 renamed to zboolean. Some C++ compilers complained about the name.
3934 Minor changes to gils.abs. Added index 's' (sort) on title
3935 and date/time-last-modified.
3937 --- 1.4pl2 1998/1/30
3939 Fixed bug in server library regarding inetd mode (-i). This bug
3940 was introduced by release 1.4.
3942 --- 1.4pl1 1998/1/29
3944 Added sort facility in client and backend server interface.
3946 Fixed problem with dependencies in Makefile(s).
3948 Fixed bugs for encoders/decoders of extended services and
3951 Implemented sub-tree feature for schemas. Sub-trees are
3952 referenced in *.abs-files. See explain.abs for an example
3953 of the use of this feature.
3955 Modified bib1.att; local attributes for ANY didn't include
3956 ANY itself (only affects use of the retrieval module).
3958 Fixed bug in plain SGML reader in function data1_read_node:
3959 tags with prefix "var" was incorrectly interpreted as variants.
3961 Added feature "sub-schemas" to enable references to - and definitions
3962 of - group of elements.
3964 * Removed member parent from type data1_element (in data1.h).
3966 Implemented function odr_nullval() that returns the value of
3969 * Removed member num_children from data1_node (in data1.h).
3971 Made NT service interface part of the server library. The
3972 function statserv_main uses the NT service when required and
3973 calls the statserv_start / statserv_close routines.
3975 Routine zget_SearchRequest and zget_PresentRequest fills
3976 resultSetName/Id member with "default" instead of "Default".
3978 Fixed memory leak in server. Request queue member wasn't freed.
3980 Fixed nmem_exit so that memory is freed.
3984 Revised the CCL parser utility to be thread safe.
3986 Added function, oid_ent_to_oid, to replace the function
3987 oid_getoidbyent, which is not thread safe.
3989 * Added nmem_init and nmem_exit to initialize and release
3990 NMEM resources. Function nmem_init should be called once in the
3991 initial thread before NMEM/ODR is used. statserv.c and client.c
3992 have been changed accordingly. The change was necessary to make
3993 NMEM thread safe. The NMEM memory pool is shared amongst threads
3994 in a process. Unix-based applications will still work fine without
3997 Added NT Services interface for the the Z39.50 (statserv) Server.
3998 Refer to the ztest.c source on the usage.
4000 Windows 95/NT port using MSVC5.0. Project files are included in the
4003 * Defined new 'global' handle for the retrieval (data1) system. The
4004 new handled, data1_handle, describes the state of the data1 system.
4005 This handle is passed as first argument to virtually all
4006 data1 related routines. The functions data1_create and data1_destroy
4007 creates and destroys a data1 handle respectively.
4009 Added ODR encode stream member to all backend request structures
4010 init, search, scan etc. This stream should be used to allocate all
4011 memory used for the response when thread safe operation is needed.
4013 Changed the comstack utility, cs_addstr, to be thread safe. The
4014 returned hostname string returned by the function is now part the
4017 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
4018 function. The cs_straddr takes a COMSTACK handle as argument, so this
4019 function must be used after cs_create and before bind/connect.
4020 This function is thread safe.
4022 Moved test server to 'ztest' directory - generic server code still
4023 in 'server' directory.
4025 Made prefix query (pquery.c) utility thread safe.
4027 Added new function modifier YAZ_EXPORT to 'export' public DLL
4028 functions when using windows (see include/yconfig.h).
4030 Added definitions to the OID database (util/oid.c) (RVDM).
4032 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
4034 Added call to ccl_rpn_delete in client program.
4036 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
4037 release of RPN structure.
4039 Added support for C++, headers uses extern "C" for public definitions.
4040 With input from RVDM.
4042 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
4043 Thanks to Ronald van der Meer (RVDM).
4045 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4047 Added support for private extensions to the OID database
4048 (oid_setprivateoids()). Thanks to RVDM.
4050 Added optional, physical ANY (key replication)
4052 Fixed null-reference problem in GRS-1 output filter.
4054 Proximity operator added to Prefix Query Format (PQF).
4056 In test client command "base" accepts multiple databases.
4058 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4062 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4064 Smallish bug-fixes in the new encoders/decoders (explain).
4066 Bug fixed in DeleteRequest.
4068 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4070 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4072 Added SOIF syntax (using private OID for now) to retrieval module and client.
4074 Added Update extended service.
4076 Added SearchResult-1 additional info structure.
4078 Added optional CCL (ISO8777) interpreter as separate module. Available
4081 --- 1.2 1996/6/10 (1st anniversary release)
4083 Added Summary record syntax. Lightly tested.
4085 Added OPAC record syntax. Untested.
4087 Added ResourceReport service encoders/decoders. Untested.
4089 Fixed bug in z_Unit - wrong tagging on unitSystem.
4091 Fixed bug in the DiagRecs decoder.
4093 Added options for max PDU size and session timeout to frontend-server.
4095 Added documentation of query-language parsers and other supporting utilities.
4097 [frontend-server] Added Attribute set to the bend_scanrequest API.
4099 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4100 surrogate diagnostics were generated.
4102 [retrieval] Allow multiple local values for attribute.
4104 [retrieval] Allow multiple attributes per element in .abs files. index type.
4106 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4108 --- 1.1pl2 1996/4/10
4110 Minor changes, mostly specific to Zebra's requirements (retrieval)
4114 Repaired bug in frontend server when running multiple listening
4115 endpoints in dynamic mode.
4117 z_External() now won't break if a known, ASN.1 value comes encapsulated
4118 in an octet-string. The value will pass through unmodified in an Odr_oct.
4120 Added a bit of code to the demo client to decode & display
4121 ASN.1-structured records represented in the octet-aligned branch of
4122 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4124 Added z_ext_getentbyref() to the ASN module. Doc updated.
4126 * Completed the SCAN definition in the ASN module. This may break SCAN
4127 code based on older YAZ-versions at compile-time. The fix is easy -
4130 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4131 under the SCAN definition. Remember to initialize this, server-people.
4133 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4134 that this does not extend to ODR and ASN.
4136 Comstack allows insertion of established socket (primarily for
4137 inetd-operation of servers). Doc updated.
4139 Front-end server can now start from the inetd in TCP mode. Doc
4142 --- 1.0pl4 1996/1/24
4146 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4147 the rank and record number.
4149 Adjustments to the frontend server.
4151 Fixed diagnostic BER dumper. It ignored the file argument.
4155 Various changes to retrieval module.
4157 Changed the union discriminators of the protocol files from enums to
4158 ints paired with #defines.
4160 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4163 *Changed operator in the RPN structure to 'roperator', again to avoid a
4166 Fixed problems in Explain decoders/encoders.
4168 --- 1.0pl2 1995/12/6
4170 Memory bug in log module fixed.
4172 --- 1.0pl1 1995/12/5
4174 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4176 Bug in Explain DatabaseInfo module fixed.
4178 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4182 The shift to v1.0 signals that we now consider the *core* functionality
4183 of YAZ reasonably stable (the core being more or less equivalent to
4184 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4185 tested (Explain not at all - though that will happen soonish).
4187 Minor changes to code to support Windows port.
4189 Various minor changes after we're getting to use GRS-1 & co. more.
4191 Added Espec-1 format.
4193 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4194 of the protocol and it cannot be selected when encoding (maps into 'string'
4195 when decoding). Needed to talk to some servers.
4197 Demo client can request simple element set names.
4199 Added Diagnostic Format encoders/decoders.
4201 Added simple Close handling to frontend server (no hooks for resource
4202 reporting yet), and demonstration client.
4204 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4206 --- 1.0b3 1995/08/24
4208 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4209 handled incorrectly when records were requested in the searchResponse. This
4210 will only affect you if you use the frontend-server.
4212 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4213 Test-client will ask for and print GRS1. Ztest will return dummy records
4216 Added Explain encoders/decoders to the service-level API. Untested.
4218 Added Extended Services: Item Order encoders and decoders to the Service-
4219 level API. Untested. We could use a recent copy of the pertinent bits
4220 of the ILL protocol to add those bits.
4222 Added diagnostic format 1 encoders/decoders to the service-level API.
4225 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4226 odr_cons.c, which causes a more correct output.
4228 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4229 was always set to 0 when no records were requested in the searchRequest.
4231 * Added better external-handling. This shouldn't harm old code that
4232 *encodes* externals. It can break code that looks for a
4233 'single-ASN1-type' representation, since those types that are known
4234 are now decoded immediately. Look at the SUTRS sample code in
4235 seshigh.c and client.c. Documentation updated.
4237 Handling of structured records in bend_fetchresponse. Length -1 marks
4238 structured record, type is deduced from format field.
4240 --- 1.0b2 1995/06/27
4241 Fairly quick maintenance release to add SUTRS support.
4243 Fixed handling of SUTRS records in the demonstration client.
4245 * Added format field to the bend_fetchrequest and bend_fetchresponce
4246 structures of the backend API (frontend server). When the record is
4247 returned, the value of the format field is mapped to an OID. The
4248 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4249 of the record. The special value VAL_NONE in the bend_request means
4250 that no specific format was requested by the client. Documentation
4251 updated accordingly. Test server (ztest) will return a fixed dummy
4252 SUTRS record if your client requests SUTRS.
4254 Documentation updated accordingly.
4256 You can now set external libraries and RANLIB support in the top-level
4260 First public release.
