3 Document zoom extraArgs YAZ-817
5 Fix ZOOM: crash extended services diagnostics YAZ-846
6 The immediate fix is to prevent ZOOM_set_dset_error from removing
7 current task from connection. This, however, has been assumed in a
8 number of places so this fix is rather large unfortunately.
12 Make yaz_log_reopen async-signal YAZ-845
13 Fixes potential dead-lock issue with YAZ_DAEMON_LOG_REOPEN flags for
18 CCL: new feature s=spl (split-list) that splits terms in a search into
19 sub-phrases of all sizes (from 1 up to the number of terms) with order
20 preserved. For 3 terms the CCL search
23 @or @or @or @and @and a b c @and "a b" c @and a "b c" "a b c"
25 Solr: don't set defType=lucene in URLs if extraArgs already defines it.
29 Add lock/unlock for YAZ log writes YAZ-843
33 Fix incorrect parsing of URLs @:9999/somebase&url=http://some.host YAZ-842
37 yaz-client: deal with excess bytes HTTPS case YAZ-833
39 ZOOM C: deal with excess bytes HTTPS case YAZ-833
41 Allow Windows installer for PATH to be updated YAZ-841
43 Add Ubuntu Vivid 15.04 to list of Deb's to built
47 Allow Content-Type application/sru+xml YAZ-840
49 New yaz_xml_get_prop utility YAZ-839
51 Fix zebrasrv [warn] ir_session (exception) YAZ-838
53 Document itemorder-setname and list all ILL options
57 Extend get_org_info (snippets) to return original string YAZ-836
58 Two new functions have appeared: icu_chain_get_org_info2 and
59 icu_iter_get_org_info2 with a 4th parameter being a pointer
60 to the original string.
62 Fix tcpip.c compilation failure on VC9 YAZ-835
64 Fix icu_iter_get_norm returns invalid size for some input YAZ-834
65 The icu_iter_get_org_info returns information based on string
66 as it appears on tokenize step.
70 Deal with excess bytes in HTTP response for keepalive YAZ-830
72 Refactor ssl_put and tcpip_put to one function YAZ-832
74 Refactor ssl_get and tcpip_get to one function YAZ-831
76 Fix SEGV yaz-client for HTTP decoding error YAZ-829
78 Fix buffer overflow in cmd_elements in yaz-client YAZ-828
82 Fix test_sru.sh fails in pazpar2 YAZ-826
83 Unfortunately a regression occurred with YAZ 5.10.0 that would make
84 Pazpar2 fail for HTTP connections.
88 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
89 Introduce cs_create_host2 which returns if connection should be
90 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
91 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
93 Fix http proxy fails with yaz-client YAZ-824
97 Fix 0 ptr reference for OPAC records from XML YAZ-822
101 Extend yaz daemon facility to assist int log rotation YAZ-818 YAZ-819
105 record conv: 'select' return org record if no x-path match YAZ-814
107 retrieval: pick matched element-set rule YAZ-813
109 Fix crash in record conv rule 'select' YAZ-812
113 record_conv: selection by X-Path YAZ-811
114 That's a new step in record conversion system (<select path=".."/>)
116 Document record render parameters for ZOOM - including base64
120 Fix application/x-www-form-urlencoded + empty YAZ-810
121 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
122 and empty content was supplied.
124 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
126 Fail hard if Bison is not found and is needed YAZ-808
130 Enable YAZ backtrace for programs YAZ-802
132 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
133 Libxml2 2.9.2, Libxslt 1.1.28.
135 Fix daemon: parent process stops before child YAZ-806
136 Try to fix the situation where parent process stops before
137 child has acknowledged it .. SIGUSR2 back!
139 daemon: log message when keepalive stops.
143 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
144 would make yaz-marcdump crash when from-character set was issued.
148 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
149 New function yaz_enable_panic_backtrace which enables backtrace
150 handler for current process. The handler will call backtrace always,
151 then gdb to provide as much detail as possible.
155 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
156 and ZOOM record render will inspect leader 9 and switch to UTF-8
157 (Unicode) if that holds 'a'. This changes behavior, but is considered
158 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
160 Fix cs_put may reconnect if send fails. YAZ-798
164 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
168 Extended comstack with outgoing IP YAZ-795.
169 For cs_create_host + cs_create_host_proxy the vhost may be followed
170 by a outgoing host/IP. Separator is blank.
174 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
175 linker error with yazpp on Windows.
179 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
181 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792
183 0 ptr reference in handling Solr response with error YAZ-791
185 Fix annoying warning about wrbuf_putc on newer GCC YAZ-789
187 Fix documentation about --installa option YAZ-788
191 daemon: properly report when receiving SIGUSR2 from child YAZ-785
195 xmalloc: throw assert for clearly invalid calls to malloc and
196 improve diagnostics YAZ-783 YAZ-784
200 Stop building debs for Ubuntu raring, quantal, oneiric.
202 CCL YAZ-781: for multiple use attributes in a specification the
203 generated RPN will perform @or on each term.
204 For spec: term u=31 u=1016
205 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
207 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
209 CCL YAZ-779: combo qualifier should allow for forward references
211 Fix buildconf.sh, automake too old on centos5 YAZ-778
212 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
213 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
214 accepts it without a warning.
218 GFS: client_query_charset conversion YAZ-777
219 This is a feature for Z39.50 clients that sends queries that are not
220 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
221 encoding given to UTF-8.
223 Echoed SRU arguments support YAZ-776
224 This is achieved with new function yaz_srw_get_pdu_e.
226 ZOOM: expire times set for redis/memcached YAZ-772
227 For both redis and memcached option --expire=seconds sets expire
228 time for a result-set/search. Default time is 600 seconds (10 minutes).
232 No [rest of output is omitted] limit for yaz_log YAZ-774
234 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
236 For ICU testing, pass -o to yaz-icu. This will test the
237 icu_iter_get_org_info function.
239 Fix null ptr reference for freeReplyObject YAZ-773
243 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
245 RPM: do not build with libmemcached support. The libmemcached library
246 on CentOS 5/6 does not work reliably for us (redis to the rescue).
248 configure: only allow libmemcached version 0.40 or later. That's the version
249 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
250 that's not an option, consider redis.
254 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
256 Fix zoom+memcached: present request out of range YAZ-767
260 CCL: add new qualifier r=omiteq which will omit relation=equals
261 for ordered relations. This should be used in combination with either
264 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
266 Solr: simplify yaz_solr_decode_response
268 Solr: use different local var for string manipulation
270 Solr: Get rid of hardcoded limit of extra_args
272 Solr: encode lucene query type YAZ-736
273 Make sure the queries are treated as traditional "lucene", because that's
276 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
280 Build packages for Ubuntu Trusty Tahr 14.04 LTS
282 wrbuf_cstr: fix off by one error.
284 wrbuf_buf: make it always return non-NULL
285 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
289 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
291 zoomsh: offer option -a apdulog
292 As we're used to from yaz-client and GFS based servers.
294 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
295 existing setting apdulog takes effect.
297 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
302 Add re-entrant CQL/Solr/RPN query conversion functions.
303 The re-entrant functions are: cql_transform_r,
304 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
305 These have same functionality as cql_transform,
306 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
307 return the additional infomration as WRBUF to make them re-entrant.
309 Remove CQL to Solr conversion and base solr_transform_t on
310 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
311 data structure as cql_transform_t.
313 cql2pqf utility allows RPN to Solr conversion
315 Fix assert in ZOOM when http connect fails YAZ-757
317 --- 5.0.22 2014/04/09
319 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
321 wrbuf_cstr: make it thread safe YAZ-753
323 yaz_log_init_file may take fd=<no> to open log file at the FD given.
325 --- 5.0.21 2014/03/21
327 Offer new utility function zget_AttributeList_use_string.
329 New conversion step, solrmarc, for record conversion module.
331 --- 5.0.20 2014/03/13
333 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
334 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
337 --- 5.0.19 2014/03/10
339 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
340 The standalone ZOOM sort was completely broken since 5.0.13.
342 ZOOM: generate event Connect rather than None for partial connect
343 (in fact getaddrinfo resolving).
345 ZOOM: only supply clientIP for InitRequest. Rather than for all
348 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
350 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
351 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
352 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
354 New "Facets" section in the documentation.
356 --- 5.0.18 2014/02/27
358 Call exsltRegisterAll in yaz_init_globals, so that all applications
359 using YAZ will have EXSLT things enabled.
361 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
363 Update various URLs to the re-organized SRU pages at LoC.
365 --- 5.0.17 2014/02/26
367 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
368 introduced in 5.0.12.
370 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
371 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
372 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
375 --- 5.0.16 2014/02/25
377 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
379 --- 5.0.15 2014/02/24
381 Fix gcrypt not properly initialized YAZ-740.
383 --- 5.0.14 2014/02/19
385 Describe memcached option for ZOOM.
387 ZOOM: throw present request out of range again YAZ-739
388 Was removed in YAZ 5.0.13.
390 --- 5.0.13 2014/02/18
392 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
393 with localtime_r when threads + fork is used (such as Metaproxy).
395 yaz-config: quote some RHS values (that might include blanks)
397 zoomsh: shows SearchResult-1
399 zoomsh: sortby command
401 zoomsh: use proper list of connections and result sets YAZ-725
403 Avoid yaz_log in sigterm handler for GFS YAZ-737
404 Logging is still performed, but outside sig handler.
406 New ZOOM C feature: result-set caching with memcached. Example:
407 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
409 Remove SSL via OpenSSL support YAZ-732
410 Also deprecate two functions from comstack that aren't working with
411 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
413 Revert "Bison: use %name-prefix directive rather than -p option"
415 --- 5.0.12 2014/01/22
417 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
419 SRU GET/Solr base URLs may hold additional ?args YAZ-729
420 ZOOM option extraArgs already does this, though. It seems useful
421 when dealing with Solr targets to limit by filter, eg.
422 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
424 Remove #fragment for HTTP request encoding YAZ-730
426 Doc: Update list of DLLs/LIBs
428 Doc: update href link to Unix utils and Git.
430 --- 5.0.11 2014/01/15
432 ZOOM: fix "lost connection" problem with servers that uses both squid
433 and another proxy behind it that returns Location headers with relative
436 zoomsh: do not use readline for stdin (no tty) YAZ-724
437 Just use fgets in that case. If the user hits Ctrl-D a new-line
440 zoomsh: empty command ignored YAZ-723
441 rather than performing exit of zoomsh.
443 yaz-url utility offers option -v to enable verbose mode.
445 yaz_url uses yaz_check_location and offers verbose mode.
447 Add new function yaz_check_location.
448 This function gets an absolute URI from Location (HTTP redirect).
450 cookie API: introduce yaz_cookies_reset
452 Update cql.y for newer bison YAZ-720
453 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
454 longer supported. Instead one must use %lex-param and %parse-param .
456 --- 5.0.10 2014/01/09
458 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
461 rpn2solr: support truncation left(2), left&right(3) YAZ-718
463 Mention SRU version 2.0 in yaz-client man page.
467 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
472 Make cs_parse_host public.A
474 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
475 introduced in YAZ 5.0.6.
479 Fix buffer corruption for yaz-ztest record fetch.
483 Allow yaz-ztest to return user-defined records (one record per file).
484 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
486 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
487 Use the stream write instead of odr_printf which has a 4K tmp buffer.
489 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
493 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
494 can read and write this format. For record format JSON, yaz-ztest returns
495 MARC-in-JSON records.
497 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
498 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
502 Improve error reporting for ICU chains YAZ-707
503 Report config element+rule when ICU status is "failure".
505 ZOOM: stop fetching if present response has no records YAZ-710
506 Some targets return less records than their hit count would suggest.
507 This prevents ZOOM from continuing to fetch records if any present
508 response has 0 records in the response.
510 Ensure that GFS calls exit if any listener fails YAZ-710
511 Before, if XML config was in use, it would start the default
516 yaz-ztest: -V shows version (like yaz-client -V)
518 New iconv encoding: danmarc YAZ-692
520 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
522 daemon: only wait for immediate child rather than all children. YAZ-704
524 yaz-client: fix setting of SRU record schema. If scheme was unset, it
525 could lead to invalid memory reference.
529 yaz-ztest returns schema for MARCXML test records. SRU require that
530 recordSchema for records.
532 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
533 instead of non-surrogate diagnostic. This is a per-record failure.
535 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
536 may refer to multiple listeners now. Attribute listenref is a comma separated
539 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
540 option is given for GFS, the dirname of filename (for -f) is used
541 as prefix for options such as cql2rpn, ccl2rpn, etc.
543 Content-Type charset fixes YAZ-701 . Do not inspect charset in
544 Content-Type header for SOAP when decoding SRU. The payload (XML)
545 itself tells what encoding it is. In response, never supply encoding
546 in Content-Type. The response payload (XML) tells what it is (with no
547 encoding in XML it's UTF-8).
549 HTTP decoding: allow blanks in URL paths YAZ-700
553 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
554 and facets. Ensure recordData and recordSchema are always present in
555 record element, because they are required.
557 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
560 Simplify in a lot of places using odr_strdupn.
562 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
566 Increase various buffers in GFS's statserv_options_block
567 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
568 This change makes many type-casts redundant, and, thus simplifies code.
570 Remove last bits of WAIS support.
572 Remove member 'size' from Odr_oct.
574 Slim down the public part of 'struct odr'. Most elements are not part
575 of struct Odr_private.
577 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
578 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
579 In particular facets are supported in both client - and server side.
580 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
581 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
582 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
583 both request/response). This is what a search handler in the GFS
584 will see (regardless of whether operating in SRU mode or Z39.50).
586 Changes to the srw.h (SRU/Solr) definitions include:
587 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
588 (char*), which replace union query and query_type (int). This is because
589 SRU 2.0 supports a queryType parameter. This also means that, to carry
590 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
591 x-pquery=PQFstring (extention parameter). The extension parameter
593 - New element, packing, that has information about SRU
594 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
596 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
598 New element, packing, in Z_SRW_explainRequest.
600 New elements in Z_SRW_scanRequest, queryType and scanClause.
601 These replace query_type and scanClase untion. This is similar to what
604 --- 4.2.69 2013/10/01
606 GFS: log when closing down - at least SIGTERM YAZ-684
607 Also change formatting WRT PID logging a bit.
609 Improve display of MARC records with multi-byte subfield IDs YAZ-695
610 In some rare cases subfield identifiers are multi-byte characters.
611 This will try to deterime length of those and split accordingly.
612 This affects display in line mode as MARCXML/MarcXchange. The encoding
613 of ISO2709 is the same.
615 Change inp argument to const for yaz_read_UTF8_char.
617 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
619 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
621 Better check of marc leader info YAZ-691
622 Problem is that some systems generate MARCXML/MarcXchange with
623 funny headers. These will not work if encoded as ISO2709.
624 Some tests produce new output, due to updated warning messages
626 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
628 yaz-client: display MAB records YAZ-689.
629 Thanks for Heiko Jansen for this patch.
631 New utility z_get_HTTP_Response_server which allows both HTTP server name
632 and HTTP server URL to be given in response.
634 Debian: do not depend on obs tcl8.3.
636 Debian: do not depend on obs libicu36-dev.
638 --- 4.2.68 2013/09/23
640 GFS: pass additionalSearchInfo to search memeber search_input if
641 given. Otherwise pass otherInfo. Request for facets and other search
642 related things will be passed there in future versions of YAZ.
644 New ZOOM setting, authenticationMode, which allows authentication
645 paramters to be encoded in the URL rather than via HTTP Basic auth.
648 rpn2solr: fix nested AND/OR handling. YAZ-685
650 Add comparison routines for some Z-types, such as NamePlusRecord,
651 RPNQuery, Query, RecordComposition and OtherInformation.
653 --- 4.2.67 2013/09/19
655 Don't decode MAB as MARC. Just like we don't attempt to decode
656 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
658 CCL: allow quoted terms for date ranges. YAZ-681
660 Introduce ccl_parser_qual_search. This function makes old function
661 ccl_qual_search, from YAZ 2, available again.
663 Add yaz_facet_list_to_wrbuf. YAZ-683
665 --- 4.2.66 2013/09/11
667 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
668 schema was given for search. YAZ-675
670 Add Solr date range searches. YAZ-621
672 --- 4.2.65 2013/08/22
674 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
676 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
678 ISO2709/MARC parse most octet aligned records; not just those that
679 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
680 MARC parse more records instead of just dumping as is. YAZ-670
682 ZOOM: proper caching for variations of record schema. YAZ-671
684 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
686 --- 4.2.63 2013/07/17
690 --- 4.2.62 2013/07/11
692 New utility z_get_HTTP_Response_details - an extended version of
695 New utility yaz_url_get_error which returns error message of last
696 failed yaz_url_exec call.
698 yaz-url and url functions: allow max HTTP redirects to be controlled.
700 New functions yaz_file_glob2, yaz_xml_include_glob.
701 These functions takes a flags parameter, which, for now only controls
702 whether to fail inclusion of a non-existing file (without glob
703 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
705 --- 4.2.61 2013/06/20
707 For MARC XML parsing, allow record without leader. A fake/default leader
708 is inserted and a warning is tagged with the record.
710 ICU: fix leak in in icu_iter_get_org_info.
712 --- 4.2.60 2013/06/14
714 ICU: fix bug in icu_iter_get_org_info (un-init variable).
716 --- 4.2.59 2013/06/11
718 Implement z_HTTP_header_remove.
720 --- 4.2.58 2013/06/11
722 ICU: Disallow 0 ptrs for some ICU string utilities.
724 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
725 returns original tokens (before normalization).
727 CCL: avoid z39.58/regex truncation when not needed. Apply only the
728 conversion of those masks, when absolutely necessary.
730 CCL: configurable masking character - @mask. Default masking character
733 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
734 full response anyway, so a Transfer-Encoding header will obstruct the
737 --- 4.2.57 2013/05/15
739 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
740 picking a socket. Problem is that some systems has IPV6 support, but
741 we can't create sockets for them, so we pick AF_UNSPEC first.
743 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
744 use content_len to determine resulting Content-Length in HTTP response
745 and NOT Content-Length supplied in headers by user.
747 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
748 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
750 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
753 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
754 with big endian and unsigned char (by default).
756 --- 4.2.56 2013/04/26
758 Fix yaz-client connect (crash in 4.2.55).
760 --- 4.2.55 2013/04/26
762 Fix proxy/host problem for ZOOM that could occur if unix sockets
765 New Debian package libyaz4-dbg.
767 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
768 differently in tcpip_close.
770 --- 4.2.54 2013/04/17
772 Windows installer of YAZ includes YAZ4J as a component.
774 CQL: allow "extra terms" again, by default. Thus, the CQL parser
775 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
776 and earlier. CQL parser may operate in strict mode where queries
777 not conforming to the standard BNF are rejected (syntax error).
778 Whether the CQL parser operates in strict mode is controlled with
779 cql_parser_strict . Strict mode enabled with option -S for utilities
780 cql2pqf and cql2xcql .
782 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
784 --- 4.2.53 2013/04/10
786 New charset, MARC-8c, which is like MARC-8 but allows control characters
787 0x01 through 0x1F, except ESC to be passed through verbatim.
789 Fix a problem with duplicate sub field character in MARC output. Problem
790 happened only when output was MARC-8 encoded.
792 --- 4.2.52 2013/04/03
794 yaz-ztest: Use hash for fake hit count. Before, random number was used.
795 This is problematic for unit tests using yaz-ztest. This patch also makes
796 a hash for CQL queries. For RPN, any term with a leading digit will be
797 treated as pseudu hit count (to force any particular hit count by a client).
799 yaz-ztest: return unique MARC dummy records. Beyond record offset
800 24, the author surname is patched with offset to make all records
803 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
804 on system wide default (/proc/sys/net/ipv6/bindv6only).
805 @4 binds to IPV4 only. @6 binds to IPV6 only.
807 Update CQL API documentation a bit
809 CQL: don't accept extra terms for queries. Makes the CQL parser
810 stricly conformant to the standard.
812 --- 4.2.51 2013/02/12
814 GFS: scan handler gets extra_args from request and may return extra
815 response data . That's for SRU only.
817 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
819 --- 4.2.50 2013/01/30
821 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
823 OPACXML: sync spelling of availabilityDate in XML to that of Schema
824 opaxxml.xsd. The schema had the correct spelling of this member always.
825 The ASN.1 was mis-spelled and still is (API change) - we are
826 not changing this. However, the OPAC to XML conversion had yet
829 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
832 New function, z_ext_record_oid_nmem, which is similar to
833 z_ext_record_oid but takes NMEM rather than ODR
835 --- 4.2.49 2013/01/18
837 ICU: New conversion element 'join' which joins tokens into one
838 with a custom character given by rule attribute.
840 --- 4.2.48 2013/01/10
842 New GFS search member: present_number. This is a hint to the
843 search handler how many records are going to be fetched immediately
844 following search. There's no guarantee that it's going to be the case,
845 since it depends on hit count (for Z39.50 piggyback) and whether errors
848 Make a few functions static (private). The functions getbyte_stream,
849 ungetbyte_stream and yaz_gets are now private. They were never declared
852 yaz-marcdump: exit(5) for serious decoding errors
854 ISO2709 decoding: be more picky WRT header
856 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
857 was only used as to indicate that next-result-set-position should be
859 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
860 Based on patch from Ashley Sanders.
862 Make some functions static/private in PQF parsing. Those functions were
863 never declared in a public header and so should not be in use by
864 applications based on YAZ.
866 --- 4.2.47 2012/11/23
868 ZOOM: special options to control APDU logging.
869 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
870 logging of APDUs until "saveAPDU" option is set again. If logging is
871 already enabled the effect is that current APDU buffer is cleared.
872 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
873 logging (default behavior on new connection).
874 The APDUs sent/received can be obtained by using
875 Using ZOOM_connection_option_get(c, "APDU") or
876 ZOOM_connection_option_getl(c, "APDU", &l).
878 GFS: relay implementation_version from backend
879 From 3.0.40 and later, implementation_version from backend was
880 not used in init response at all.
882 --- 4.2.46 2012/11/15
884 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
885 mode at all. Probably never did.
887 Make a new version of ztest.pem that, at least, is not expired.
889 --- 4.2.45 2012/11/13
891 Fix description of CCL directive 'case'.
893 More tight checking of form arguments (yaz_uri_to_array). Makes
894 YAZ better at rejecting big and/or bad POSTs.
896 SRU decoding does not report more than up to 10 invalid arguments.
898 rpn2cql: less quotes in generated terms. Semantics unchanged, but
899 it's prettier this way.
901 --- 4.2.44 2012/10/25
903 New utility yaz_decode_init_diag. Defined in proto.h.
905 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
906 given for unix local socket.
907 The COMSTACK string for doing so is:
910 unix:/myfile:tcp:localhost:9999/mybase
911 unix:/myfile:localhost:9999/mybase
912 unix:/myfile:http://fakehost/mybase
914 debian: Use dpkg-buildflags in build process.
916 --- 4.2.43 2012/10/19
918 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
919 global's SRU service uses a recordPosition scheme starting from zero.
920 First record's position should be one
921 according to the standard.
923 --- 4.2.42 2012/10/18
925 Allow more namespaces for SRU. This is to allow, for example, an
926 incorrect namespace returned from server
927 http://services.igi-global.com/sru .
929 Minor fixes for compilation on Windows.
931 --- 4.2.41 2012/10/11
933 daemon: log total number of bad signals from child on stop so that it
934 is more easy to spot problems with child worker processes.
936 retrieval: empty backend name attribute omits element set
937 from being used in retrieval.
939 --- 4.2.40 2012/10/04
941 Implement Solr sort strategy "solr", similar to sru11 sorting.
942 This will implement the correct parameters on Solr requst to do
945 --- 4.2.39 2012/09/28
947 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
950 MARC: Extra/missing indicator handled for MARCXML.
951 The indicator length is given in header and is the same for the
952 whole record. If attributes ind1, ind2 are missing, then content
953 character defaults to blank. Extra indicator attributes (beyond)
954 indicator length are treated as an error.
956 Reformat: delete trailing whitespace
958 --- 4.2.38 2012/09/17
960 MARC: fix non-ASCII characters for leader. This is to ensure we can
961 generate XML in UTF-8.
963 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
964 in one node with structure word.
966 --- 4.2.37 2012/09/04
968 yaz-json-parse: JSON output may be pretty printed by using option
971 Increase default value of max message for Z39.50 Init for GFS, ZOOM
972 and yaz-client. Old value was 1 MB. New value is 64 MB.
974 --- 4.2.36 2012/08/22
976 yaz-client: don't display bogus records from SRU servers. Some SRU servers
977 return more records than given by *maximumRecords*. Skipping those in
980 record_render: simplify buffer return handling and fix at least one bad
981 memory reference, that broke the test_embed_record sometimes.
983 Allow http://user:pass@host notation for yaz_url_exec.
985 zoomsh: allow shell command to be executed. Via the system(3) call.
987 yaz_poll: Allow num_fds == 0
989 yaz-client: fix bad encoding of "itemorder item". The itemorder
990 item <no> - command forgot to use length of encoded Item Request
991 package. Error present since YAZ 3.
993 yaz-ztest: fix bad usage of session handle. Bug was introduced when
994 result sets were saved (271a9c83).
996 SRU recordPacking: guess record packing in response rather than looking
997 at the recordPacking element which, OF COURSE, changed semantics in SRU
1000 Decode SRU 2.0 responses. The official namespace for responses, according
1001 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
1002 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
1003 nature.com's server, however, usee namespace
1004 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
1005 we are now using a glob-expr to match up the namespace. ZOOM C and
1006 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
1007 I can not find a single real example showing the "real" namespace in
1008 the documentation from OASIS. The namespace for requests is different
1009 from responses, but this is not added to YAZ yet, when we don't encode
1012 --- 4.2.35 2012/06/26
1014 zoom/record_render: add support for Base64 decoding fo MARC records
1015 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
1016 which will decode base64 + ISO2709 marc-8 encoded material from text node
1019 --- 4.2.34 2012/06/07
1021 Add missing definitions ZOOM_resultset_get_facet_field_by_index
1022 and ZOOM_resultset_facets_names.
1024 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
1027 Change APDU dump printing to avoid long leading blanks. For levels 16
1028 or larger the level is shown and the indentation is truncated but
1029 recursed with modula 8. This makes it still reasonable easy to read
1030 - even for nested BER dumps.
1032 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
1033 return 0 (incomplete package) in case where the BER package was
1034 considered too nested (return value of -2).
1036 dumpber: lines of level 15 are not indented further. Two spaces per
1037 indentation; indentation 15 or more is indented to a fixed indentation
1038 and augmented with a level=<no> indication.
1040 zoomsh: increase max size of command+args
1042 GFS: No limit in RPN buf size in CQL to RPN conversion.
1044 --- 4.2.33 2012/05/09
1046 New function for daemon utility, yaz_daemon_stop .
1048 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
1050 --- 4.2.32 2012/04/25
1052 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
1053 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1055 --- 4.2.31 2012/04/23
1057 YAZ daemon utility relays SIGUSR1 to child process.
1059 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1060 would result in en empty database list - which in turn would result in
1061 encoding failure for search.
1063 Fix reading beyond string in yaz_sort_spec.
1065 --- 4.2.30 2012/04/11
1067 Add two new SRU diagnostics:
1068 236: Access to specified database denied
1069 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1071 Document the very useful ZOOM-C option "apdulog".
1073 CQL to RPN: term may be passed through verbatim. This is enabled with
1074 truncation.cql . The assumption being that the term is already CQL.
1076 --- 4.2.29 2012/03/20
1078 record_conv: leader spec may be given for marc element.
1079 The leader spec is given as attribute leaderspec for element marc.
1080 For example to convert a MARC21 record from MARC-8 to UTF-8:
1081 <marc inputformat="marc" outputformat="marc"
1082 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1084 record_conv: allow user-XSLT params. For example:
1085 <xslt stylesheet="MARC21slim2DC.xsl">
1086 <param name="myparameter" value="myvalue"/>
1087 <param name="otherparameter" value="othervalue"/>
1090 record_conv: fix error handling for missing marc charsets.
1092 CQL: fix extra terms in wrong order.
1094 --- 4.2.28 2012/03/06
1096 record_conv: modify new API for conversion types. The conversion types
1097 may be passed in new functions yaz_record_conv_configure_t and
1098 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1100 Avoid mixed statement/variable declare; fixes compilation with Visual
1103 --- 4.2.27 2012/02/28
1105 Add non-standard SRU diagnostic: 235: "Database does not exist".
1106 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1107 Update SRU to Bib-1 diagnostic maps accordingly.
1109 CCL: add two new diagnostics for unsupported masking. The new
1110 diagnostics are: "Embedded truncation not supported" and
1111 "Single charcacter mask not supported".
1113 --- 4.2.26 2012/02/23
1115 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1117 --- 4.2.25 2012/01/11
1119 Build YAZ for Ubuntu Oneiric.
1121 CCL: allow parantheses for proximity operands. For example CCL query
1122 (a) % (b) is now allowed.
1124 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1125 marked dead, rather then being destroyed. If not, the session memory is
1126 being free'd before the search/scan handler is finished. Also destroy
1127 'request' memory in request_release rather than in various places,
1128 which resulted in leaks from time to time.
1130 --- 4.2.24 2011/12/21
1132 cql_sortby_to_sortkeys: honor sort prefix.
1134 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1135 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1136 The rpn2cql family of functions now always returns quoted CQL terms.
1138 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1140 --- 4.2.23 2011/12/15
1142 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1143 sequence is treated as one. For example, &&a=b&&&c& is identical to
1146 --- 4.2.22 2011/12/05
1148 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1149 APDUs for a connection to a WRBUF.
1151 --- 4.2.21 2011/11/23
1153 Fix cql_sortby_to_sortkeys. Completely broken before.
1155 Make CCL's @truncation work again.
1157 --- 4.2.20 2011/11/09
1159 New ZOOM connection setting: tproxy. It's like proxy, but does not
1160 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1161 to set resolved address + port for a connection outside ZOOM itself.
1163 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1165 --- 4.2.19 2011/11/07
1167 Fix uninitialized variable in Solr spell support (could cause SEGV
1168 for SRU response decoding).
1170 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1171 back-end's addinfo through into the ZOOM response addinfo.
1173 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1174 they are separated by a colon and a space rather than simply
1177 --- 4.2.18 2011/10/28
1179 Add support for Solr spell-checking/suggestions through ZOOM.
1180 If a Solr target has been configured correctly for spelling-checking
1181 and suggestions, these will now be returned on the ResultSet option
1182 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1184 --- 4.2.17 2011/09/28
1186 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1187 with a flag whether to substitute escape sequences or not.
1189 --- 4.2.16 2011/09/22
1191 Fix nmem_strsplit_escape to substitute escape char properly.
1193 New option for zoomsh -e , which makes it abort on first error and
1194 return process exit code to indicate success/failure.
1196 YAZ options utility supports special option -- which makes all it treat
1197 all following arguments as non-options.
1199 --- 4.2.15 2011/09/16
1201 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1202 searched if absolute filename is given.
1204 Fix conv_xslt() error-reporting when stylesheet is not found.
1205 (The value of fullpath is meaningless in this situation.)
1207 --- 4.2.14 2011/09/07
1209 Fix problem in CQL sort node creation: un-initialized memory.
1211 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1212 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1213 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1216 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1217 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1219 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1220 will make it possible to use both single-character mask (#) and wildcard (?)
1221 in CCL . Throw diagnostic for left truncation because that is not supported
1224 --- 4.2.13 2011/09/01
1226 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1227 cases using escapes (\-sequences) and masking.
1229 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1230 would result in a read one byte beyond string.
1232 rpn2ccl may use Z39.50 masking for terms (t=z).
1234 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1236 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1237 not --cppflags (which seeems like an error in icu-config).
1239 --- 4.2.12 2011/08/27 RPM package only
1241 cql2ccl: fix conversion of terms: operator characters were not
1244 --- 4.2.11 2011/08/25 RPM package only
1246 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1247 CCL parser will map both # and ? to their regular expression
1248 quivalents (. and .*).
1250 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1251 of reserved CQL characters.
1253 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1254 is, so that they are passed through.
1256 --- 4.2.10 2011/08/24
1258 ZOOM SRU mode: more aggressive re-connect.
1260 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1261 made available as a utility function, declared in <yaz/logrpn.h>
1263 rpn2cql_structure() supports proximity nodes (except that the Type-1
1264 proximity node's "exclusion" binary is ignored, as there is no way to
1265 express that in CQL). Fixes bug #4564.
1267 --- 4.2.9 2011/08/18
1269 Fix SEGV that could occur if set command of zoomsh was given without
1270 value (2nd argument).
1272 Fix SEGV that could occur if unsupported transport was given for
1273 COMSTACK - say https (when SSL was unavailable).
1275 Build yaz-url on Windows too.
1277 --- 4.2.8 2011/08/11
1279 New utility to get web content. Header is url.h. A command line tool
1280 yaz-url is part of the distribution and packages.
1282 Fixes for SSL COMSTACK (when gnutls is in use).
1284 New functions yaz_base64{encode,decode}. Header is base64.h.
1286 --- 4.2.7 2011/08/03
1288 ZOOM C includes HTTP response buffer as additional info if it fails
1289 to decode the SRU response.
1291 Make wrbuf_json_puts available.
1293 --- 4.2.6 2011/07/28
1295 zoom: throw diagnostic for invalid value for option "sru". Before a
1296 bad SRU request was sent.
1298 Adding new utility wrbuf_vp_puts.
1300 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1302 --- 4.2.5 2011/07/21
1304 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1305 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1306 redirect was used at the same time.
1308 MARC line mode decoding: be less picky about length given - first
1309 5 digits of header that is.
1311 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1313 Changes to decoding of SRU records: a record with recordPacking=xml is
1314 modified with a new root element <yaz_record> if the recordData contains
1315 multiple children elements. This is to make the record XML parseable
1318 RPN to Solr conversion: encode special characters.
1320 Generic Frontend Server: fix uinitialized member, stepSize.
1322 --- 4.2.4 2011/06/21
1324 Fix a bug in SRU decoding of records.. The database records stored
1325 had un-initialized memory, but it would only be seen with yaz_record_render
1326 and type_spec="ext" .
1328 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1330 --- 4.2.3 2011/06/17
1332 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1334 --- 4.2.2 2011/06/10
1336 Add new utilities to convert from CQL to CCL . These utilities have
1337 prefix cql_to_ccl defined in cql.h.
1339 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1340 lead to memory heap corruptions when ICU utilities were in use.
1342 --- 4.2.1 2011/06/07
1344 Make compilation work without Libxml2.
1346 yaz-client: remove redundant blanks in display of searchResult-1 term
1349 --- 4.2.0 2011/05/18
1351 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1352 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1354 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1355 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1356 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1357 Note that the CQL sortby spec is only converted when the GFS is already
1358 converting from CQL to RPN (cql2rpn element).
1360 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1361 specify whether to collapse delimitors or not. The existing nmem_strsplit
1362 do collapse (collapse parameter = 1).
1364 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1366 Rename internal func yaz_use_attribute_create. While non-static, this
1367 function is not declared in a public header.
1369 --- 4.1.7 2011/03/15
1371 Add -lCrun when linking with ICU on Solaris.
1373 More quicks character set conversions for OPAC records.
1375 --- 4.1.6 2011/03/10
1377 fix problem with record_render: records were converted (character set
1378 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1380 --- 4.1.5 2011/03/08
1382 SRU: add methods for handling DADS SRU-proxy facets.
1384 Separate OPAC record character set for ZOOM_record. yaz_record_render
1385 allows a character set given as charset=from/opacfrom,to where 'from' is
1386 the character set of a bibliographic record, 'opacfrom' is character set
1387 of OPAC record and 'to' is the target character set.
1389 --- 4.1.4 2011/02/21
1391 yaz-client: show may XML format records. Command show followed by 'format'
1392 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1395 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1398 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1400 --- 4.1.3 2011/01/27
1401 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1403 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1404 this package can be distinguished from other vendors.
1406 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1407 as determined by configure
1409 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1411 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1412 returns no error and no record, the present request is considered
1413 partial (only a subset of the records could be returned by backend), and
1414 so it is appropriate to set Present Status to partial-4.
1416 --- 4.1.2 2010/11/02
1418 Move yaz-config man pages to section 1.
1420 More documentation about Solr.
1422 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1423 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1424 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1425 peers on some Linux systems. However, in general that does not work
1426 so YAZ can not rely on that to work. Debian changed behavior in this
1427 respect from Debian lenny to Debian squeeze (still testing as of Oct
1429 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1431 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1433 --- 4.1.1 2010/10/05
1435 Fix yaz-config output: echo_source not set correctly by configure.
1437 --- 4.1.0 2010/10/05
1439 Solr Web Service support for yaz-client and ZOOM.
1441 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1443 --- 4.0.12 2010/08/17
1445 Z39.50 facet support. Facet specifications are passed for search in
1446 other-information with ASN.1 as defined in facet.asn and OID
1447 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1448 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1449 3 is limit (number of entries to get in response). yaz-ztest returns
1450 dummy facets if a client asks for them.
1452 --- 4.0.11 2010/07/09
1454 CCL fixes: bug 2895 and bug 3539.
1456 GR1-display: add comma in display - was removed by mistake in
1459 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1461 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1463 --- 4.0.10 2010/06/18
1465 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1466 result set from a connection. The result set will be on its own
1467 thereafter; no operations on it will perform retrievals from a target.
1468 Only cached copies are returned.
1470 ZOOM C:fix case for HTTP servers responding with Connection:close.
1471 Ensure that if there is a current task it is resumed (like fetching
1472 more records in a result set) . Bug #3484.
1474 PQF parser: use odr_atoi for Odr_int (not atoi)
1476 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1477 values that contain any non-digits are treated as string attributes
1478 (previously decoding only checked for leading character ([0-9]). PQF
1479 encoding: attribute string values are not surrounded by double-quotes.
1481 --- 4.0.9 2010/05/21
1483 New utility for managing threads - thread_create.h.
1485 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1486 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1487 but YAZ' implementation do.
1489 Fixes for yaz_cond-functions on Windows 7.
1491 DLL export more symbols.
1493 zoomsh: show record do NOT render opac.
1495 Remove *.la files from Debian and RPM packages.
1497 --- 4.0.8 2010/05/11
1499 Debian package libyaz-dev depends on libgnutls-dev again (was
1500 removed in YAZ 4.0.6, but due to Libtool it is still needed
1501 even though yaz-config do not list libgnutls libs).
1503 ZOOM: Use only one WRBUF for returning string results for
1504 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1506 ZOOM: ZOOM_connection do not use a shared pointer to
1507 ZOOM_resultset after ZOOM_resultset is destructed by
1508 user. Reverts to YAZ 4.0.4 behavior.
1510 --- 4.0.7 2010/05/04
1512 record-conv: fix problem with at least one XSL conversion -
1513 due to probably incorrect usage of XML XSL documents.
1515 --- 4.0.6 2010/04/29
1517 Fix yaz-config for static mode and the use of SSL (gnutls).
1519 --- 4.0.5 2010/04/29
1521 Forward decl timeval struct in mutex.h and gettimeofday.h.
1523 yaz-config: fix 'static' mode linking.
1525 --- 4.0.4 2010/04/28
1527 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1528 are wrappers for pthreads or Windows. For Windows these are put in
1529 a separate DLL: yaz_cond4.
1531 libyaz.la (whole source) is compiled with thread. If thread support
1532 is enabled enabled, all source of YAZ is compiled with treading support.
1533 This allows core utilities such as yaz_log to use thread facilities.
1534 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1535 thread utilities. This commit moves mutex utilities (mutex.c) from
1536 libyaz_server.la to libyaz.la.
1538 yaz-json-parse displays leading text until error.
1540 --- 4.0.3 2010/04/09
1542 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1543 patch from Giannis Kosmas.
1545 SRU: no longer URL encode SRU database. The URL for an SRU server is
1546 a URL and such is alreeady encoded - at least when given with leading
1547 http:// or https://. This reverts behavior to YAZ 3.0.50.
1549 Support for new MARC XML notation TurboMARC which like MARCXML is a
1550 complete representation of MARC/ISO2709.. This one, however, is more
1551 compact and allows for faster processing with XSLT. TurboMARC can be
1552 used in the marcdisp.h API, from the yaz-marcdump utility and from
1555 yaz-ztest can be configured - via the database - to perform certain
1556 delays when it performs operations search, present and single record
1557 fetch. This allows testers to make yaz-ztest act as a real or even slow
1558 Z39.50 server. Refer to the yaz-ztest man pages for details.
1560 --- 4.0.2 2010/03/09
1562 wrbuf_destroy allows NULL WRBUF passed to it.
1564 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1566 Add ZOOM_connection_close.
1568 No fixed size buffers for ZOOM shell - bug #3257.
1570 tstodr: make it work on s390 platform.
1572 New icu iterator-functions. The new icu_iter-functions makes it possible
1573 to use ICU chains from many threads.
1575 yaz-client: better syntax check for show command.
1577 --- 4.0.1 2010/01/26
1579 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1582 New simple local-file XML include facility which allows file glob-patterns.
1583 Refer to yaz/xml_include.h.
1585 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1588 ZOOM_record_get supports new parameter "format" which makes it format XML
1591 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1592 JSONText in ECMA-262) is JSONValue, not JSONObject.
1594 --- 4.0.0 2010/01/20
1596 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1597 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1599 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1600 POSIX/Unix builds .so with major version 4.
1602 Remove old LOG_-defines from log.h. They have been obsolete and
1603 undefined by default for the last 5 years.
1605 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1607 GFS: Remove socket (int *fd) from search_rr handler. The socket
1608 descriptor ptr is a facility that allowed a search handler to supply
1609 a socket which would serve as a callback - when search was complete.
1610 This facility has now been in use for years.
1612 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1613 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1614 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1615 returns 'const char *' rather than 'char *. The returned string is
1616 read-only and should not be modified by applications. COMSTACK cs_close is
1617 now a void function - it no longer returns int. No applications check for
1618 the value and the implementations has always returned 0.
1620 ZOOM: use size_t for scan hit counts and str size. Functions
1621 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1622 occ (hit count) and len (string length) are now of type size_t pointer
1623 rather than int pointer. This is to be able to represent large hit counts
1624 and to also just to use the proper type for string length (strlen result).
1626 New JSON parser. Refer to include/yaz/json.h .
1628 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1629 Used to be int in some cases. Many wrbuf_-functions used to return an int
1630 indicating some length.. These return values were never used. And so they
1633 ODR: odr_malloc, odr_total now takes size_t for size.
1635 clone_z_type: fix leak; occurred for encoding failures.
1637 --- 3.0.52 2009/12/03
1639 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1640 bug was introduced in 3.0.51.
1642 --- 3.0.51 2009/12/02
1644 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1646 tcpip comstack: fix leak for getaddrinfo.
1648 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1649 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1650 Decoding of SRU "path" database is performed by private function
1651 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1652 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1654 yaz-client: honor base command for SRU. Change when database setting
1655 is applied for SRU and ensure it is kept when a connection is reset.
1656 Change also the way errors are displayed or SRU (decoding of packages).
1658 --- 3.0.50 2009/11/02
1660 Add support for extra request / response data for SRU codecs and GFS.
1661 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1662 for extra data response buffer and length. For the GFS, both request
1663 and response data (XML) is carried in extra_args and extra_response_data
1664 for the search handler. Patch by Ko van der Sloot.
1666 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1667 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1668 10010). This fixes bug #2113.
1670 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1671 cmdfile included a 'quit' command that would result in a memory violation.
1673 --- 3.0.49 2009/10/01
1675 Make a number of functions defined in xmlquery.c static. These have
1676 never been declared in a public header file (yaz/xmlquery.h) and was
1677 made public by mistake.
1679 Improve speed of character conversions (iconv utilities). This makes
1680 conversions from MARC-8 faster.
1682 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1683 unless type desired is "raw". This will prevent type "xml" from
1684 returning ISO2709 .. Which obviously can not be XML parsed.
1686 Fix memory leak in ZOOM that would occur if option apdulog was used
1687 on a re-used connection.
1689 Frontend server logs HTTP requests.
1691 Frontend server now sends Z39.50 close when it times out (sesssion has
1692 been idle for too long). Versions 2.0.30 and earlier also sent close.
1693 But due to a mistake this was disabled in all versions after that, i.e.
1694 the server would just close the socket immediately.
1696 yaz-client emits a better message when receiving an unrecognised
1697 userInformationField.
1699 Skip zero-length subfields when decoding ISO2709. This rare case happens
1700 if a record has two FS characters in a sequence. Without this patch
1701 there would be a reference beyond char array in using_code_len fragments
1704 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1706 --- 3.0.48 2009/08/28
1708 The show command offered by the zoomsh command now takes a 3d optional
1709 parameter type which is what is passed to ZOOM_record. If the type
1710 argument is omitted, "render" is used.
1712 RPN to CQL conv may use USE string attributes (bug #2978).
1714 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1716 --- 3.0.47 2009/07/08
1718 Function yaz_xml2query allows a diagnostic element in the PQF XML
1719 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1720 code and additional info respectively.
1722 The BER BOOLEAN is now the integral type Odr_bool which still happens
1723 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1724 typedef'd to Odr_int. This is still an integral 'int', but it may be
1725 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1726 ASN-1 compiler as well as programs has been updated to use the new types.
1728 --- 3.0.46 2009/06/08
1730 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1731 only the bibliographic record was rendered. For type=opac, an OPAC
1732 record is only returned if it is present.
1734 iconv: small fix for encoding of advancegreek.
1736 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1738 yaz-client: option auto_reconnect=on really reconnects.
1740 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1742 server: avoid null ptr ref for for yaz_poll errors.
1744 build: fix RPM build for RHEL 5.3.
1746 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1748 --- 3.0.45 2009/03/31
1750 Fixed bug #2709: TCP connect returns Invalid argument.
1752 Fixed compilation for mingw.
1754 Honor charset for raw records (ZOOM_record_get).
1756 Fixed use of errno for threaded mode that was seen on Solaris 10.
1758 Fixed argument passing with blanks in value for Windows Service.
1760 Disable YAZ' own log rotate by default (no 1 GB limit).
1761 The variable l_max_size which specifies the log file limit is set to 0
1762 (DISABLED): This is due to the fact that YAZ is most often deployed using
1763 logrotate. Also YAZ can not perform log rotate because of unsufficient
1764 permissions (setuid).
1766 --- 3.0.44 2009/02/17
1768 List supported encodings in man page for yaz-iconv.
1770 Fixed missing SSL libs for --libs output
1772 Re-established OID record syntax application-xml. Nobody should use it
1773 but we don't want to change soname because of this symbol being absent.
1775 --- 3.0.42 2009/02/02
1777 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1779 Added member named_result_sets for init handler struct for the GFS. This
1780 allows a server to disable named result sets.
1782 Removed OID record syntax application-xml.
1784 Added support for rule-based transliterator for ICU wrapper of YAZ.
1786 Fixed bug #1902: yaz-icu XML output.
1788 Make YAZ checks Emacs friendly.
1790 BITSTRING value shows value. Bug #2346.
1792 ISO2709 decoding: skip control characters from indicator data.
1794 Omit sort key by default in yaz-icu's output.
1796 Allow combined single char options (again) for YAZ' options function.
1798 Utility yaz-marcdump got option to display YAZ version (-V).
1800 Allow YAZ to use ICU 3.4.
1802 Added new ICU test case which illustrates removal of diacritics.
1804 --- 3.0.41 2008/12/29
1806 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1808 --- 3.0.40 2008/12/29
1810 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1813 Fixed bug #2352: yaz-marcdump crashes for certain record.
1815 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1817 Added support for Danmarc2 to UTF-8 conversion.
1819 Added support for ISO5426 to UTF-8 conversion.
1821 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1822 implementation version.
1824 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1826 --- 3.0.38 2008/11/10
1828 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1829 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1831 ZOOM C now interprets databaseName option for ZOOM connection as path
1834 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1836 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1838 Dummy Libxml2 types no longer defined in headers of YAZ'.
1840 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1843 --- 3.0.36 2008/09/26
1845 Various ODR chapter fixes.
1847 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1849 Added missing source for Windows compilation, mutex.c.
1851 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1853 For SRU connections in ZOOM all records up to "count" are now fetched.
1855 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1856 in Windows due to bad error handling for Libxml2.
1858 Added facility for sending arbitrary records (ASN.1 any) using
1859 ZOOM C's Extended service update. Patch by Sam Reynolds.
1861 New options for ZOOM C's connection, logapdu which makes ZOOM log
1864 --- 3.0.34 2008/06/18
1866 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1868 --- 3.0.32 2008/06/12
1870 Fixed memory violation that could occur when decoding UTF-8. This bug
1871 was only present in 3.0.30 of YAZ.
1873 --- 3.0.30 2008/06/06
1875 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1876 GNU TLS is used by default (if found).
1878 yaz-ztest returns OPAC records if a client asks for OPAC.
1880 Improved speed of MARC-8 encoding.
1882 Added support for lossy and loss-less MARC-8 encoding.
1884 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1886 Added new Windows Service wrapper (sc).
1888 yaz-client's itemorder command may now send a file.
1890 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1892 Added new function yaz_log_xml_errors.
1894 Allow (but warn) unknown XML attributes in MARCXML parsing.
1896 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1898 The UTF-8 to MARC-8 conversion now uses a different set of characters
1899 for Greek symbols. Bug #2120.
1901 --- 3.0.26 2008/02/21
1903 Added yaz_daemon (daemon.h).
1905 Fixed bug #2068: pkg-config trouble
1907 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1909 --- 3.0.24 2008/01/28
1911 Document --with-xml2 option.
1913 Added OPAC XML XSD (etc/opacxml.xsd).
1915 Allow glob mask for name attribute in retrieval element for the
1916 generic frontend server's retrieval facility.
1918 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1919 except POLLIN/POLLOUT.
1921 Fixed error handling in cs_listen. Bug #2037.
1923 --- 3.0.22 2008/01/20
1925 Fixed version in yaz/yaz-version.h.
1927 Fixed bug #2027: Crash when closing connection.
1929 Changed configure so that ICU support is only enabled if only ICU
1930 and Libxml2 is available (because the ICU chain is XML based).
1932 --- 3.0.20 2008/01/15
1934 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1935 is built. Only this DLL depends on the ICU runtime.
1937 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1938 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1940 Changed license of CCL module to 'Revised BSD'. After consultation with
1941 remaining members of the original EUROPAGATE consortium, we are re-issuing
1942 the CCL module without a separate license. The software was developed by
1943 Index Data as part of a research project. The special license was included
1944 to help feed usage information back to the project consortium to support
1945 project evaluation. At this time, the project consortium has long-since
1946 disbanded, and the majority of the original principals have retired. At the
1947 same time, we have significantly modified the software during the following
1948 years, to the point where very practically no original code remains. To
1949 simplify re-use of the software, we have contacted those members of the
1950 consortium who could be reached, and agreed to re-issue the module as a
1951 proper part of the YAZ package.
1953 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1955 CQL closer to being version 1.2 compliant. CQL also allows free-form
1956 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1959 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1960 bug could make Extended services handling crash in the ZOOM layer. This
1961 bug was only present in YAZ 3.0.18.
1963 --- 3.0.18 2007/12/19
1965 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1968 yaz-marcdump reads and writes collection wrapped records.
1970 Handle OPAC for record conversion module.
1972 Fixes for ICU wrapper.
1974 Allow ICU libs to be controlled with --with-icu .
1976 --- 3.0.16 2007/11/12
1978 Added yaz_poll which is a wrapper for select/poll. When poll is available
1979 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1980 sockets to be in use.
1982 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1983 functionality through an XML based configuration (ICU chain). This system
1984 is useful for search facilities such as Pazpar2 and Zebra that needs to
1985 perform tokenization of indexed material. The ICU code in a separate
1986 library libyaz3_icu.a.
1988 Added HTTP tunnel facility for COMSTACK, bug #1752.
1989 This is a facility that allows a Web proxy, such as squid, to tunnel
1990 Z39.50 traffic. This facility is "transparent" to must applications
1991 using YAZ. It's enabled by using pseudo transport connect: followed by
1992 the proxy address, followed by command, then follwed by he regular
1993 "virtual" addresss. For example,
1994 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1996 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1998 --- 3.0.14 2007/09/21
2000 Fixed bad memory reference in ZOOM_record - cuased by member not being
2001 initialized. This was a problem only in YAZ 3.0.12.
2003 Fixed bug in conversion from MARC to XML: Non-XML characters in control
2004 fields were not removed.
2006 Changed the way C code is generated from codetables.xml. Made a MARC-8
2007 conversion trie for each characterSet section rather than codeTable.
2008 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
2009 of codetables.xml from Larry Dixson, LOC. Bug #1464.
2011 --- 3.0.12 2007/09/12
2013 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
2014 from ZOOM_record_error).
2016 ZOOM C function ZOOM_record_get returns record schema for type="schema".
2018 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
2020 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
2022 Better SRW-to-Bib-1 diagnostic mapping.
2024 ZOOM C and yaz-client announces SRU version 1.2 by default.
2026 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
2029 Fixed in yaz_sru_decode to allow other version than 1.1.
2031 --- 3.0.10 2007/08/22
2033 Added support for SRU scan for ZOOM.
2035 Added support for the use of the older versions or Extended Service
2036 Update in ZOOM. To faciliate this, an option "updateVersion" may be
2037 set to the version , 1=first, 2=second, 3=third. The third version is
2038 what ZOOM C has used so far. And that, obviously, is the default.
2040 Added support for CCL queries in Z39.50 queries sent to the GFS (and
2041 therefore in Zebra and in SimpleServer-based applications). The new
2042 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
2043 qualifier file used to transform incoming CCL queries into Type-1 RPN,
2044 which is passed into the back-end search callback function.
2046 Added support for HTTP Basic authentication in clients: the SRU/W
2047 codec encodes the username/password elements of the PDU structure
2048 appropriately, and these may be set using the "user" and "password"
2049 options in ZOOM-C applications (the same options that are used for
2050 Z39.50 authentication).
2052 --- 3.0.8 2007/06/25
2054 Fixed bug #1208: SSL appears to be broken in ZOOM.
2056 Fixed bug #1206: Libxml2 include path weirdness.
2058 Added oid_name_to_dotstring.
2060 Allow elementSetName to be specified for ZOOM C record update.
2062 Allow waitAction to be specified for ZOOM C based for Extended Services.
2064 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2065 syntax OID. Bug introduced in YAZ 3 series.
2067 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2069 --- 3.0.6 2007/06/06
2071 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2072 directory. yaz-client now reads commands from file given by option -f
2073 if specified; then tries to read .yazclientrc in current directory.
2074 Failing that, it reads .yazclientrc from user's home directory.
2076 Added support for correlationInfo Note and ID for Record Update via
2079 Added yaz-client command querycharset which specifies character set for
2080 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2081 (termListAndStartPoint).
2083 Charset ISO5428:1984 is an alias for ISO5428-1984.
2085 Implemented a way to perform scan in a result set using Z39.50. This
2086 is achieved by attaching the result set name in the characterInfo
2087 (type InternationalString) of OtherInformation in the Scan Request PDU.
2088 The result set is identified in the otherinformation by the new OID:
2089 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2090 This allows for scan in result set and faceted search . Zebra did some
2091 of this in the APT term using attribute type 8 and value being result
2092 set. Using the OtherInformation approach for this is cleaner and easier
2093 to work with in proxies and the like. This facility can be used in
2094 yaz-client using new command setscan which takes a result set as first
2095 argument, start position (APT) as second.
2097 Changed decoding of SRU XML packed records to deal with servers that
2098 have recordData with XML data with multiple root nodes. Also make
2099 comparison for recordPacking case insensitive. Again, one server
2100 returns "XML" where others return "xml".
2102 For SRU responses allow Content-Type application/xml as well as text/xml.
2104 --- 3.0.4 2007/05/21
2106 Fixed bug in character set conversion of BER strings. Bug introduced
2109 --- 3.0.2 2007/05/08
2111 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2113 For OID class, use oid_class consistently.
2115 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2118 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2119 character set for bibliographic information interchange". By Giannis Kosmas.
2121 Added documentation on new OID API.
2123 --- 3.0.0 2007/05/02
2125 Changes to generic frontend server interface: added new member
2126 'query_charset' for bend_initrequest structure. A backend init handler
2127 should set this member to its native character set for query terms.
2128 When defined, the frontend server logic will announce this character set
2129 to a client if the negotiationModel bit is set by the client. All server
2130 implementors are encouraged to specify this. If a backend server does not
2131 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2133 Added CCL utility to remove terms (stop words) from resulting RPN
2134 tree. This is handled by functions with prefix ccl_stop_words_ .
2136 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2137 terms in RPN queries.
2139 Clean-up the CCL API. Moved some internal structures from ccl.h to
2140 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2141 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2142 This is replaced by ccl_parser_find_str which takes a string instead.
2144 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2145 libyaz.la is the core of YAZ except the generic frontend server and
2146 does not depend on POSIX threads anymore. libyaz_server.la is the
2147 generic frontend server facilities and uses POSIX thread functionality
2148 if available. The libyaz.la no longer depends on POSIX threads because
2149 the number of global structures is limited. NMEM no longer re-uses blocks
2150 between threads ; it simply free's memory immediately but allocates in
2151 "large" chunks as usual. We don't expect any performance penalties
2152 because of this. The yaz_log system is still using a global log_level so
2153 caution must be taken when modifying it with yaz_log_init_.. +
2154 yaz_log_mask_str. This, however, should not cause any trouble because
2155 these functions are called during initialization of application code
2156 anyway. `yaz-config --libs server` returns libs for server applications;
2157 `yaz-config --libs` returns libs for non-server applications.
2159 New OID database - with public definitions in oid_db.h. Removed old OID
2160 database including the head oid.h and definitions such as enum oid_value
2161 and struct oident. The new OID database uses the same string names as
2162 before but the 'protocol' is gone. There are now only two representations
2163 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2164 converts from string to OID; functions with prefix yaz_oid_to_string
2165 converts the other way.
2167 Change to emit_term() in CQL-to-PQF query translation: when a term has
2168 the /regexp relation modifier, do not process it for leading and
2169 trailing "^" and "*", which have quite different meanings in regular
2172 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2173 write handlers no longer carries a 'last' parameter. This will make
2174 yaz_iconv flush "less" characters. A flush is performed by call to
2175 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2177 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2178 removed, because function yaz_query_to_wrbuf does the same.
2180 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2181 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2183 Deprecated MARC utility functions removed.
2185 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2188 Branch split: YAZ_2_1_55_branch
2190 --- 2.1.54 2007/03/16
2192 Fix to ZOOM-C so that transparent reconnection is properly handled on
2193 connections that are in asynchronous mode.
2195 Fixed compilation on OpenBSD 4.0.
2197 Large strings in GRS-1 records are now properly displayed in yaz-client.
2199 Added character conversion support for "advancegreek"; based on patch from
2202 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2203 sequence is met. Before the error was not set so it would be unknown.
2205 Adjust yaz-marcdump MARC reader so that it skips until record separator
2208 --- 2.1.52 2007/03/07
2210 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2211 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2212 fd_set structure used as a bitmask for the FDs to be selected on.
2214 Using ACX_PTHREAD macro to check for POSIX threads.
2216 Fixed have-vsnprintf check.
2218 --- 2.1.50 2007/02/23
2220 Fixes for configure on BSD. Bug #900.
2222 Added snprintf/vsnprintf wrappers for systems that don't have
2223 limits (heavens forbid).
2225 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2226 created before all previous tasks were completed and removed from the
2227 task queue, the new task could be removed by a mistake.
2229 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2231 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2233 Fixed bug #832: Problem with MARC/charset in yaz-client.
2235 Fixed bug #668: save command line history for yaz-client.
2237 Fixed bug #830: pkg-config support.
2239 --- 2.1.48 2007/01/23
2241 Extended ZOOM result set options with two options that may be read by
2242 a client: resultSetStatus and presentStatus with values as specified for
2244 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2246 Fixed bug #827: Using SSL fails on Debian etch.
2248 Fixed bug #826: Weird looking chars for set of MARC records.
2250 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2251 that is treated as an ItemOrder with itemRequest being an XML document
2252 external. The value of "doc" is the content.
2254 Extended the GFS search facility. New member of bend_search_rr
2255 'estimated_hit_count' signals that hits is known to be an estmate
2256 (higher or lower than real hit count). New member 'partial_resultset'
2257 signals that the search was partial (hit count is lower or equal than
2258 real hit count). For Z39.50, the information is stored in resultSetStatus
2259 member of SearchResponse APDU. For SRU, the information is signalled
2260 via SRU diagnostic 59: "Result set created with valid partial results
2263 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2265 --- 2.1.46 2007/01/13
2267 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2269 Added ZOOM_connection_peek_event.
2271 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2272 the following new functions:
2273 ZOOM_event_nonblock, ZOOM_connection_process,
2274 ZOOM_connection_get_{socket,mask,timeout},
2275 ZOOM_connection_fire_event_{timeout,socket}.
2276 The existing blocking event handler, ZOOM_event, is a wrapper for the
2277 + blocking ZOOM_event_sys_{poll,select}.
2279 Implemented function ccl_xml_config which parses XML version of CCL
2280 configuration (bug #798).
2282 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2284 Added timings utility (yaz/timing.h)
2286 --- 2.1.44 2007/01/03
2288 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2291 Fixed bug #779: Rotation of apdu.log fails.
2293 Fixed for character set conversions:
2294 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2295 Honor G1 set in MARC-8 decoding.
2297 --- 2.1.42 2006/12/17
2299 Fixed bug #775: char conversion does not handle Alternative UTF-8
2302 Implemented function yaz_marc_read_line which parses MARC line format
2303 records. There is a wealth of formats out there. So far, this function
2304 reads line records produced by yaz_marc_write_line.
2306 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2307 more generic and easier to remember(!) options: -i format and -o format
2308 which specifies input format and output format respectively - where
2309 format is one of "marc", "marcxml", "line", "marcxchange".
2311 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2312 does not print anything except warnings for records.
2314 For yaz-marcdump, added support for MARC split into files (-s) with a given
2317 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2318 spec, at http://www.loc.gov/standards/sru/record-update/
2319 This has changed the binary layout of the following structs:
2320 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2321 bend_update_rr . Patch by Ko van der Sloot.
2323 Added GFS utility function bend_assoc_is_alive which returns 1 if
2324 association is still alive (client is connected); 0 otherwise (client
2325 closed connection). This allows busy servers to stop working for
2328 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2329 been a separate piece of software. This version of ziffy has been modified
2330 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2332 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2334 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2335 Client code may now interrogate options such as "init_opt_sort" to
2336 find out whether the server claims to support various options.
2338 --- 2.1.40 2006/11/27
2340 Added utilities yaz_{set,get}_esn to set/get element set name from
2343 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2344 of YAZ and has been so since YAZ 2.1.10.
2346 Implemented ZOOM_record_error which returns error information for
2347 record (surrogate diagnostic).
2349 --- 2.1.38 2006/10/31
2351 Updates for SRU Update by Ko van der Sloot:
2352 1. Changed name from "operation" to "action"
2353 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2354 versions in the code, marked as 'backward compatible'.
2355 3. Added diagnostics for SRU Update.
2357 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2359 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2361 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2363 For GFS, fixed problem with SRU diagnostic 'First record position out of
2364 range' being issued for 0 hits.
2366 zoomtst10 part of Windows Build.
2368 --- 2.1.36 2006/10/13
2370 Implemented yaz_filepath_comp which splits a path into file path
2371 components (required by Zebra 2.0.3+).
2373 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2374 BSD inspired license until now so this should not have any real impact on
2375 anybody. See http://www.opensource.org/licenses/bsd-license.php
2377 Fixed bug #687: Missing log lines.
2379 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2382 Fixed bug #689: SRU diagnostics to be added.
2384 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2385 whether a connection is idle (no more work do do).
2387 --- 2.1.34 2006/10/04
2389 Change type of optval from long to int for invocation of setsockopt with
2390 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2392 Added support for specifying the max log file size for the Generic
2393 Frontend Server. The size is given with option -r.
2395 --- 2.1.32 2006/09/21
2397 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2399 --- 2.1.30 2006/09/17
2401 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2404 Fixed bug in Generic Frontend Server that could cause a server to stop
2405 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2407 For the generic frontend server, the maximum record size is used as maximum
2408 size of incoming packages (SRU + Z39.50). The value until was previously
2409 only used in Z39.50 Init negotiation and, later, in a session controlled
2410 sizes of records returned. This is controlled using -k option. It can be
2411 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2413 --- 2.1.28 2006/09/04
2415 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2418 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2420 New option for yaz-marcdump -lpos=value which allows setting a portion
2421 of MARC header to a certain value.
2423 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2425 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2426 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2428 --- 2.1.26 2006/08/15
2430 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2433 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2435 --- 2.1.24 2006/08/08
2437 Fixed MARC ISO2709 encoding routines to deal with character set
2440 Minor changes to GFS logging. Database included in search request log
2443 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2444 cached/multiple records.
2446 Shared libraries are built by default on Unix+configure.
2448 Changed cql2pqf transformation to use a different evaluation order. The
2449 new order is: always, relation, structure, position, truncation, index
2450 and relationModifier. Old order was: always, relation, relationModifier,
2451 structure, index, position, truncation. Note that the the latter ones
2452 override former ones for identical attributes.. The new scheme means that
2453 it is possible to override any existing attribute with a relationModifier.
2454 And also that it is possible to override everything for the index rule
2455 (except the ones listed in relationModifier). No order is perfect but this
2456 one, we believe, covers more real cases.. The "always" should have been
2457 called "default", since the attributes there can be overridden with all
2460 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2461 compilation phase, but also for yaz-config --cflags output. This allows
2462 us to have public headers with Libxml2 stuff in them . It should also,
2463 eventually, make Libxml2 checks redundant in packages using YAZ, such
2466 --- 2.1.22 2006/06/15
2468 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2469 stored in uri, message and details.. Previously diagnostics were stored
2470 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2471 compatibility.. but he's probably the only one affected, so.
2473 Added support for CCL, compiled on the client side, in ZOOM-C. This
2474 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2475 input; the resulting query objects can be used for for searching with
2476 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2478 YAZ' configure searches for OpenSSL by default.
2480 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2481 SL_CTX_use_certificate_file. See
2482 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2483 for more info. Thanks to Ko van der Sloot.
2485 --- 2.1.20 2006/06/02
2487 Bug #600: SRU GET, POST support for yaz-client. Introduced
2488 command 'sru' which selects method SOAP/GET/POST.
2490 Allow missingValueAction to be specified for the sortspec string -
2491 function yaz_sort_spec. By default, the missing value action is null.
2492 Use ! to specify "abort". Use = followed by stringvalue to specify default
2495 Ensured that Present-handler (if defined) is called in GFS before any call to
2496 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2497 searchRetrieve requests.
2499 Documentation for YAZ is now based on the Docbook XML/XSLT using
2500 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2501 is no longer depending on jade/openjade or docbook-to-man scripts.
2502 PDF is no longer part of the distribution - but can optionally be
2503 made using DSSSL/jadetex or FOP.
2505 Added retrieval handling support in Generic Frontend Server to support
2506 conversion between MARC/XML as well as XSLTtransforms. See
2507 etc/yazgfs.xml for an example.
2509 Added Authentication support to Generic Frontend Server in SRU
2510 mode. Authentication using HTTP Basic is supported, as is the use
2511 of 'x-username' and 'x-password' parameters in the request itself.
2513 Added support for a new character set MARC8s identical to MARC8 except
2514 that it converts combined characters to single Unicode characters in the
2515 Latin-1 range (when possible).
2517 --- 2.1.18 2006/04/24
2519 ASN.1 compiler 0.4: generates brief Doxygen file header for
2520 generated .h/.c files.
2522 Utility yaz_iconv now supports conversion to MARC-8.
2524 New facilities for the MARC module. The reading - and writing of
2525 content are separate methods for the yaz_marc_t handle. The following
2526 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2527 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2528 format). Write functions have prefix yaz_marc_write_.. The existing
2529 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2530 available. Removed support for OAI-MARC and simplexml (not the
2531 simplexml from PHP5).
2533 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2534 to be returned for this connection.
2536 --- 2.1.16 2006/03/31
2538 Allow multiple languages and charsets to be specified with
2539 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2540 negcharset iso-8859-1,utf-8
2542 Translation of proximity nodes from CQL into PQF now works.
2544 Moved to automake 1.8, 1.9.
2546 Added function yaz_log_set_handler which allows a log handler to be
2547 installed. This handler will be called for all log messages. Output
2548 to file is also produced; but that can be disabled by passing NULL
2549 fname to yaz_log_init_file.
2551 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2553 For SRW (including GFS), accept application/soap+xml as content-type
2556 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2557 produces NO stylesheet reference even if a default stylesheet is specified
2560 --- 2.1.14 2006/03/14
2562 Updated Windows package to include yazd.dll + yazd.lib for the
2563 Development component.
2565 If the environment variable YAZ_LOG is set, then it is used as a
2566 string indicating the default level of logging to use if not
2567 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2568 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2569 used as before. So, for example, to omit warnings from YAZ logging,
2570 export YAZ_LOG=-warn
2572 cql_transform() now map structure and other attributes before indexes,
2573 so that index-specific structures and other attributes can override
2574 defaults. So now a combination of mapping specifications such as:
2576 index.dc.date = 1=date-modified 4=5
2577 does the right thing.
2579 cql_transform() now also respects the "always" mapping specification,
2580 which establishes an initial set of attributes to be used for all
2581 terms except where overridden by more specific attributes associated
2582 with the index, relation or modifier.
2584 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2585 which mode to use; one of "post", "get" or "soap" (SRW, default).
2587 Fixes for yaz_iconv routines: changed trie-based character set conversions
2588 to use only non-negative values for bit fields due to Sun's C compiler not
2589 supporting negative values.
2591 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2592 sequences where not read correctly. Fix by Rustam Usmanov.
2594 Updated win/makefile to use options, settings which makes things
2595 compile with VS C 2005.
2597 --- 2.1.12 2006/02/01
2599 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2601 In ZOOM socket code, use select instead of poll on MacOSX.
2603 ZOOM-C now support client-side compilation of CQL into RPN that is
2604 sent to the server, enabling CQL to be used against all Z39.50
2605 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2606 ZOOM_query object, and submit it using ZOOM_connection_search().
2607 The CQL-to-RPN translation uses a configuration file, the name of
2608 which must be specified in the Connection's "cqlfile" option.
2610 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2611 function, which takes as its start-term parameter a ZOOM_query object
2612 (which may have had either CQL or RPN set into it).
2615 --- 2.1.10 2005/11/29
2617 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2618 GFS to support this as well. Backend handler, bend_srw_update, does the
2619 update work. Code contributed by Ko van der Sloot.
2621 Allow retrieval of Search Result-1 information in ZOOM by the use of
2622 options that are attached to a result set. ZOOM documentation updated
2625 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2626 UTF-8 conversion. Patch by Raj Patel.
2628 Added option -m to GFS to control formatting of timestamps in log file.
2630 Added 'exit' as synonym for 'quit' in yaz-client
2632 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2633 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2634 for the new members. Patch by Ko van der Sloot.
2636 Added support for SRU POST. It is supported for content-type
2637 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2639 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2640 Instead make the library libyaz.la multi-threaded. Threading as a whole
2641 can still be disabled by configure option --disable-threads. Previosly,
2642 with older GLIBCs there were problems with MT libs under Apache. This
2643 has now been fixed a long time ago.
2645 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2648 CQL module modified to be case insensitive for relations/indexes/operations.
2650 Fixed bug in CQL transform code: incorrect value relationModifieder
2653 Added 'show all' command for yaz-client which retrieves all results
2656 Added new yaz-client, xmles, which takes a (private) OID and
2657 a document to be sent as an extended service request.
2659 Describe new yaz-client commands wait_response and set_auto_wait.
2661 Increase TCP/IP listener backlog from 3 (which I am guessing was
2662 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2663 that the socket will queue as many incoming connections as it's able
2664 to handle ongoing connections. In other words, it will never now
2665 refuse a connection that it would be able to handle merely because
2666 it's not got around to accepting() enough of the pending connections
2667 yet. This is the behaviour anyway under Linux, where the listen()
2668 argument is ignored; but not under BSD and on systems such as
2669 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2670 YAZ-based servers should now be uniform across operating systems in
2673 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2674 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2675 This allows yaz-marcdump to read large MARC batches (>2 GB).
2677 Modified all YAZ source files - except the source which is auto-generated
2678 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2681 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2682 corresponding to the existing *_setl() function. These allow option
2683 values containing arbitrary valuues.
2685 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2686 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2687 except that it returns an indicator of whether or not the sort
2688 criterion was accepted (0 for OK, -1 for invalid).
2690 --- 2.1.8 2005/06/07
2692 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2693 MARC output rather than returning "new" buffer.
2695 yaz-client warns about unknown init options.
2697 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2699 --- 2.1.6 2005/05/24
2701 Added support for SRW sort in Generic Frontend Server. Patch
2702 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2703 sortKeys - or NULL if none is provided.
2705 Fixed bug #307: It was impossible to specify indefinite/no timeout
2706 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2709 Added support for multiple languages and charsets to be specified in
2710 ZOOM. Each charset/language is separated by a blank. If negotiation is
2711 in effect in init-response, Option
2712 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2713 Code based on patch by Vasiliy Osadchuk.
2715 Fixed bug #306: infinite recursion that occurred when calling
2716 yaz_log_level_init as the first call (before other log level or
2719 Fixed bug in scan handling in front end server: if preferred-Position-In-
2720 Response was non-present, a NULL pointer referece was performed.
2722 --- 2.1.4 2005/04/26
2724 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2725 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2726 now defined for all those error codes. So instead of putting 109 in
2727 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2728 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2730 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2733 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2735 Program yaz-client now exits and produces an error message if multiple
2736 Z39.50 servers are specified on the command line (none or one allowed
2739 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2742 --- 2.1.2 2005/03/16
2744 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2746 Fixed bug #272: Preserve spacing for CCL terms.
2748 --- 2.1.0 2005/03/14
2750 Added support for virtual hosts and multiple backend servers for
2751 the YAZ frontend server. The configution is XML based and
2752 support specificition of CQL to RPN mappings and explain information.
2753 See section "Virtual Hosts" in the YAZ manual.
2755 Extended OPAC display utility. OPAC display utility renders
2756 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2757 to supplement yaz_marc_decode_wrbuf.
2759 Fixed a bug in MARC decoder that could caused it to crash for some
2760 invalid MARC records. More diagnostics and warnings where added in
2761 XML output (warnings, etc are stored in comments).
2763 --- 2.0.34 2005/02/08
2765 Fixes for UNIX domain sockets. Bug #261.
2767 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2769 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2770 Added yaz_marc_subfield_str which defines subfield lead string which is
2771 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2772 yaz_marc_endline_str which defines end of fields string used in
2773 YAZ_MARC_LINE format. Default string is newline.
2775 Experimental support for MarcXChange. This format can be produced
2776 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2777 http://www.bs.dk/standards/MarcXchange.xsd
2779 Added yaz-client commands scansize that sets maximum number of
2780 entries to be returned by scan.
2782 --- 2.0.32 2005/01/11
2784 Added support for SRW scan in yaz-client and Generic Frontend Server.
2786 * Added whereInList member to SRW Scan Term.
2788 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2790 Fixed NMEM system to return aligned blocks on the smallest boundaries
2791 that are suitably aligned for all possible types on the particular
2792 architecture YAZ is being built for.
2794 --- 2.0.30 2005/01/04
2796 Fixed numerious warnings that was issued with newer versions of GCC.
2798 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2799 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2802 Make YAZ Generic Frontend Server slightly faster.
2804 Enhance (and reduce) logging for Generic Frontend Server.
2806 Revert YAZ log system so that it flushes every write operation
2807 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2809 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2810 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2811 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2812 will effectively disable old definitions.
2814 --- 2.0.28 2004/11/09
2816 Added yaz_log_time_format which specifies log format using
2819 Added yaz_log_module_level which returns mask for a module. Value
2820 is non-zero mask a if module is enabled; zero if disabled.
2822 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2823 in include/yaz/cql.h.
2825 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2827 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2829 Fixed bug #172: RPM builds does not enable SSL.
2831 Doxyfile.in part of dist. Doxyfile generated by configure.
2833 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2834 are given and the corresponding component does not exist.
2836 Extend CCL documentation in YAZ reference. Describe r=r.
2838 --- 2.0.26 2004/10/01
2840 Fixed MARC->MARCXML conversion to properly deal with
2841 fields, subfields, indicators having non-ASCII characters.
2843 Fixed MARC->MARCXML conversion so that ASCII control characters
2844 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2847 Added YAZ GFS support for conversion from Z39.50 surrogate
2848 diagnostics to SRW surrogate diagnostics.
2850 Bug fix: YAZ GFS did not return schema in explainResponse.
2852 --- 2.0.25 2004/09/30
2854 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2855 now converts recordSchema to elementSetName as well as schema URI.
2857 Fixed bug in COMSTACK that prevented HTTP request packages from being
2860 --- 2.0.24 2004/09/29
2862 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2863 does not require white-space before and after the dash in a range, e.g.
2864 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2867 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2868 due to new GCC removing "redundant" code.
2870 Added yaz-client commands scanpos and scanstep that sets preferred
2871 position and step-size for scan.
2873 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2875 Added CCL utility ccl_qual_buf which parses one or more CCL
2876 spec lines in a buffer.
2878 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2879 of name and value - ignoring empty lines and comments.
2881 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2883 Added odr_get_element_path which returns current element path for an
2884 ODR handle. This utility is useful in error handling or user-defined
2887 Added ODR_PRINT utility odr_set_stream which is is a more generic
2888 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2889 to a write function and pointer to close function. The close function - if
2890 non-NULL - will be called during odr_destroy.
2892 Fixed bug in CCL parser where truncation char was not removed from
2893 right side when truncation=both was in effect.
2895 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2898 --- 2.0.23 2004/08/11
2900 Fix buffer overrun in CQL parser when dealing with proximity (%).
2902 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2903 to UTF-8/UCS conversion is now only based on codetables.xml.
2905 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2907 --- 2.0.22 2004/08/06
2909 Add support for more "commit changes" in ZOOM (uses Extended Services).
2911 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2914 Yet another small fix for configure of SSL.
2916 --- 2.0.21 2004/05/14
2918 Fix SSL libs for configure when --with-openssl=DIR is given.
2920 --- 2.0.20 2004/05/10
2922 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2924 SSL comstack now uses yaz.pem certificate file on server side
2925 by default. Certificate filename can be configured by calling
2926 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2928 Fix bug regarding multiple calls to ZOOM_connection_connect.
2930 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2932 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2933 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2935 ZOOM now allows inspection of X509 peer certificate for verification.
2936 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2938 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2939 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2940 as "modular" but it simplifies things.
2942 Added cs_get_peer_certificate to that returns peer X509 PEM.
2944 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2945 NULL if SSL is unavailable.
2947 Documentation about MARC decoding tools.
2949 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2951 --- 2.0.19 2004/03/30
2953 Rename CHANGELOG to NEWS to follow GNU style packing.
2955 Fix bug with missing initialization of member in init_diagnostics.
2956 This bug affects threaded version of GFS server.
2958 --- 2.0.18 2004/03/20
2960 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2963 Ensure zlib.dll is packed with Windows install.
2965 --- 2.0.17 2004/03/17
2967 Fix encoding of xsd:string to use text instead of CDATA.
2969 Fix endless loop in CQL parser with unbalanced ".
2971 Use a more compact way to store MARC-8 conversion tables.
2973 --- 2.0.16 2004/03/16 Debian only
2975 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2978 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2983 --- 2.0.15 2004/03/01
2985 Another fix for decoding of XML packed records.
2987 --- 2.0.14 2004/02/25
2989 Fixes for Chunked encoding. White space not ignored after length spec.
2991 Update NS and use default NS for SRW diagnostic elements.
2993 --- 2.0.13 2004/02/23
2995 Implement ZOOM_resultset_cache_reset which resets record cache.
2997 Implement ZOOM_resultset_sort which sorts a result set.
2999 Implement chunked HTTP transfer.
3001 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
3003 --- 2.0.12 2004/02/16
3005 Added member 'schema' to bend_explain_rr structure so that backend
3006 can specify explain record identifier. Defaults to Zeerex 2.0.
3008 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
3010 --- 2.0.11 2004/02/16
3012 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
3015 Added init command for yaz-client which sends "extra" init request.
3017 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
3018 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
3020 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
3022 Make ZOOM error code for "invalid query".
3024 Fixed compilation for SSL which wasn't properly enabled for all platforms.
3026 --- 2.0.10 2004/02/05
3028 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
3031 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
3033 Added option -p <file> to make Generic Frontend Server to write PID file.
3035 Added option -D to put Generic Frontend Server in background on its own.
3037 Make ZOOM C recognize option "password". If unset, "pass" is used
3038 (for backwards compatibility).
3040 Fixed a bug in Generic Frontend Server that could make it crash if a
3041 client sets characterSetNegotation bit, but didn't pass negotiation stuff
3044 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
3045 Must be issued before open, in order to be in effect.
3047 --- 2.0.9-6 2004/01/12 Debian/Windows
3049 Make the SRU server more picky WRT unknown params, etc.
3051 Bug fix: ZOOM scan response didn't return displayTerm - when present.
3053 New YAZ client command, options, that sets Z39.50 options.
3055 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3056 options from a string of tokens (one token for each option bit).
3058 Update SRW diagnostic code messages.
3060 --- 2.0.9-5 2004/01/07 Debian/Windows
3062 Handle user defined stylesheet for SRW/SRU.
3064 --- 2.0.9-4 2004/01/06 Debian/Windows
3066 Fix bug in decoding of Content-Length.
3068 --- 2.0.9-3 2004/01/06 Debian/Windows
3070 Fix a bug with decoding of XML packed records.
3072 --- 2.0.9-2 2004/01/05 Debian only
3074 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3076 Fix bug in SRW/SRU diagnostics decoding.
3078 --- 2.0.9 2004/01/05
3080 Fixed bug in Generic Frontend Server which could drop records exceeding
3081 preferred message size. Reported and fixed by Irina Dijour.
3083 Fixed calculation of package size for structured records in Generic
3084 Frontend Server. Reported and fixed by Irina Dijour.
3086 Fixed namespace for SRW/SRU diagnostics.
3088 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3090 --- 2.0.8 2003/12/22
3092 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3093 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3096 CQL changes to reflect recent changes to the specification:
3097 * Documentation talks about context sets instead of index sets.
3098 * Documentation talks about indexes instead of qualifiers.
3099 * The CQL-to-PQF transformer's configuration file now uses
3100 "index.set.name = <attributes>" instead of the old form
3101 "qualifier.set.name = <attributes>". (Both forms are still
3102 understood but the latter is deprecated.)
3103 * CQL terms with no explicit index specified are now interpreted as
3104 cql.serverChoice instead of srw.serverChoice (which of course
3105 behaves exactly the same.)
3107 --- 2.0.7 2003/12/16
3109 MARC conversion can now generate ISO2709 output in another
3110 character set. yaz-marcdump uses this facility if you invoke it
3113 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3114 functions from there can be used from C++.
3116 --- 2.0.6 2003/12/04
3118 Frontend server now transfers memory from decoded packages to stream
3121 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3122 references to show up.
3124 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3125 the ZOOM Abstract API. The older names for the same options are still
3126 also supported for the benefit of old applications.
3128 ZOOM-C supports "implementationId" and "implementationVersion" options
3129 to go along with "implementationName". These allow the user code to
3130 specify identification strings to be sent to servers.
3131 Add OID for the new ExtLite attribute set.
3133 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3134 as requested/supplid by Ere Maijala <ere@atp.fi>
3136 For generic frontend server, reverse the order of
3137 "toolkit-supplied / application-supplied" strings sent as implementationId,
3138 Name and Version. Also, remove the spaces around the slash. This brings
3139 the GFS in line with the behaviour of ZOOM-C on the client side.
3141 Add function ZOOM_scanset_display_term.
3143 yaz-client shows scan displayTerm if present.
3145 Utility yaz-iconv is now installed by default along with the man page
3148 Extend configure check for OpenSSL to use pkg-config where available (such
3151 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3152 server to specify uid/gid/mask for socket using the format
3153 unix:[user=uid,][group=gid,][umask=mask,]file=path
3154 If file= is omitted the existing format is assumed, e.g.
3156 in which case the mask is 0666 (rw for everybody).
3158 Major restructure of YAZ source. All source in libyaz is in src directory.
3159 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3160 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3162 Added man page for utility yaz-marcdump (used to be called marcdump).
3163 yaz-marcdump is installed by 'make install'.
3165 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3166 of incoming package failed.
3168 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3170 Change prototype of odr_perror: add const to message string.
3172 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3174 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3175 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3176 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3177 DNS lookup. There should not be any compatibility problems with this
3178 assuming that blocking=1 or 0 is used.
3180 Fix bad reference in UNIX comstack in function cs_addrstr.
3182 Fix for compilation on AIX.
3184 The generic front-end server (server/seshigh.c) now supports returning
3185 Init diagnostics to the client in User-information-field, in
3186 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3189 --- 2.0.4 2003/09/04
3191 Allow any CQL relation (not just all,any,exact,scr).
3193 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3194 that features the same UI.
3196 Implemented command update0 in YAZ client which is equivalent to
3197 update but uses old of Ext Update ASN.1.
3199 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3200 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3201 Previously no OID was used for this info.
3203 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3204 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3205 returns 'malformed search term' otherwise.
3207 SortResponse member resultCount now set to NULL in sort handler of
3210 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3213 Add three new utility functions for translating OIDs between various
3214 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3215 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3216 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3217 char *oid_to_dotstring(const int *oid, char *oidbuf);
3218 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3220 Reverted modifications for ES Update definition for z_IU0Update
3221 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3222 is back to YAZ 2.0.2.
3224 String value attributes for CCL parser.
3226 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3227 which their FirstSearch server returns in Init responses, sometimes
3228 carrying useful diagnostic information when Init fails. This has the
3229 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3230 "z39.50/oclcui.asn", where its definition is somewhat different from
3231 what OCLC document on their web-site, as required to interoperate with
3234 Support for anonymous authentication in yaz-client. Use the command
3237 * Fix the OID of the Index Data-local "admin" Extended Service from
3238 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3239 the 1000, which indicates a locally-defined OID, was a mistake.
3241 --- 2.0.3 2003/06/20
3243 Fix CCL directive @case handling so that it affects string match for
3244 both CCL keywords and qualifiers.
3246 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3247 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3248 Decoder has been updated with ASN.1 changes as listed in
3249 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3250 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3251 z_IUUpdate, remains unchanged.
3253 ZOOM_record_get may now return a record in a specific character set.
3254 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3255 "from" is the character set of record as returned by target. "to" is
3256 the character set to be returned. If omitted, "to" is UTF-8.
3258 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3260 New ODR utility, odr_getelement, which returns name of element for
3261 which encoding/decoding failed.
3263 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3264 in cases where a required element was omitted.
3266 Bug fix: some MARC8 sequences were not converted.
3268 New ZOOM option "step" which specifies number of records to be
3269 retrieved in one chunk. Used in conjunction with "start" and "count".
3271 SRW support for yaz-client. Use scheme http: to use it, e.g.
3274 yaz-client no longer does (un)intelligent character set conversions
3275 by default. Can be enabled with charset and marc_charset commands.
3277 xmalloc trace fix for 64-bit systems such as DEC alpha.
3279 Solaris 2.6 compile fix.
3281 New function, cql_strerror() translates SRW error codes, as returned
3282 by cql_transform_error(), into human-readable English strings. Used
3283 in yaz-client diagnostics when appropriate.
3285 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3286 converts it into a type-1 query which is sent to the server. This
3287 makes CQL available for use with all Z-servers, as opposed to the tiny
3288 minority that can handle CQL queries themselves.
3290 --- 2.0.2 2003/04/28
3292 New Debian package layout similar to the Redhat Package layout.
3294 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3295 and search result respectively.
3297 --- 2.0.1 2003/04/25
3299 Redhat package is now several packages: libyaz (runtime libraries),
3300 libyaz-devel (development and documentation, and yaz (utility programs).
3301 Package spec file by Morten Bogeskov.
3303 New member 'schema' in struct bend_fetch_rr which the name of requested
3304 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3305 handler MAY set this to reflect the schema of the returned record.
3307 New member 'display_term' in struct scan_entry. GFS now sets member entries
3308 and allocates scan entries to be filled by user scan handler. In previous
3309 version, entries member was allocated by the scan handler. That still works,
3310 but the GFS will ignore member display_term - assuming it was NOT set by
3311 the handler. The fact that the GFS now allocates the entries both allows
3312 for new members and makes a scan handler easier to write.
3314 Fix CQL lex buffer overflow.
3316 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3317 SRU default recordPacking is string.
3319 SRU protocol support for frontend server.
3321 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3323 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3325 Added scan for the ZOOM shell (zoomsh).
3329 * String Identifers for Schemas (Amendment 5).
3330 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3331 Old definition for schema
3332 Odr_oid *schema; /* OPT */
3337 Z_InternationalString *uri;
3338 #define Z_Schema_oid 1
3339 #define Z_Schema_uri 2
3342 * resultCount parameter to Sort Response (Amendment 1).
3343 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3345 Support for SRW 1.0 over HTTP. This is an optional feature and
3346 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3349 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3350 on the same port. SRW SearchRetrieveRequests are mapped
3351 to bend_init,bend_search,bend_fetch,bend_close.
3353 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3355 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3356 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3358 ZOOM connections are SRW based if schem http is used for hostname
3359 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3360 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3362 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3363 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3364 distance=n, order=true/false, relation=le, prox unit=word. If
3365 n is omitted, distance 1 is used.
3367 Fixed problem with C compiler include path in wrong order.
3369 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3370 on Solaris. Patch from Ko van der Sloot.
3372 New MARC decode API. All new functions operate on a yaz_marc_t
3373 handle. The most important new functions are: yaz_marc_create,
3374 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3375 decode and destroy respectively. Decoder can produce formats
3376 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3377 include/yaz/marcdisp.h.
3379 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3380 to UTF-8, UCS-32, wchar_t or Latin-1.
3382 * Prototypes for yaz_iconv_-functions moved to separate header
3383 include/yaz/yaz-iconv.h.
3385 Make a few private functions 'static' in unix.c. This prevents
3386 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3388 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3389 are set when Init Response is received.
3391 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3392 but returns diagnostic set as well.
3394 New function yaz_strerror which is a portable wrapper for
3395 strerror/strerror_r/GetLastMessage.
3397 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3398 is returned for MARC. If type is "oai", then OAI MARC is returned.
3400 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3403 --- 1.9.2 2002/11/26
3405 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3407 Fix bad race conditions on SIGTERM and terminate gracefully in
3410 Move retrieval (data1) module to Zebra since nobody seems to be
3413 Add GRS-1 render for ZOOM using same format as yaz-client.
3415 --- 1.9.1 2002/10/05
3417 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3419 Fix broken ESpec handling in data1 module.
3421 SGML reader parses comments and makes them part of the data1 tree.
3423 Added several type casts so that YAZ compiles as C++ code.
3425 ZOOM didn't handle PDU encoding failures properly.
3427 Added more Bib-1 diagnostics (approved extensions).
3429 GNU configure: better check for iconv.
3431 More portable use of accept, getpeername. Check for socklen_t. Use
3432 int/size_t if socklen_t is not defined.
3436 PQF parser rejects bad queries - including those with extra
3437 characters in them. PQF parser used to silently ignore that.
3438 Cleaner API for PQF added, which allows you to get detailed
3439 error information for bad queries (see yaz/pquery.h).
3441 Fixed bug in ZOOM_record_get for type "database".
3443 Implemented mini iconv library supporting conversions between
3444 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3446 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3448 --- 1.8.9 2002/08/20
3450 Fixed ZOOM C record cache so that preferredRecordSyntax and
3451 elementSetName is used to check for already fetched records.
3453 --- 1.8.8 2002/08/02
3455 Added three members in bend_initrequest structure to facilitate
3456 character set negotiation.
3458 Fixed a bug in frontend server that could cause indefinite
3459 loops under rare conditions.
3461 Revised character set utilities (charneg.h) so that encoding
3462 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3464 For PQF, directive @term <type> sets term type for Scan/Search.
3465 Here <type> is general, string, numeric, null. The term type
3466 is inherited - just like @attr.
3468 New call odr_set_charset that sets character set conversion for
3469 international-strings on a ODR stream. Prototype is:
3470 int odr_set_charset(ODR o, const char *to, const char *from);
3471 The InternationalString is still represented as C string in YAZ
3472 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3473 won't). On the protocol level, you can use any encoding.
3475 Support for UNIX sockets in ZOOM.
3477 Solaris recv sometimes returns errno == ENOENT. It is treated as
3478 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3480 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3481 both client and server. Code by Morten Bogeskov.
3483 --- 1.8.7 2002/05/22
3485 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3486 that they can be used directly from Visual Basic. You must recompile
3487 your windows APP if you're using ZOOM.
3489 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3490 Commands "lang" and "charset" sets language and character set respectively.
3491 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3492 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3494 Attributes from multiple CCL fields may be OR'ed rather than merged
3495 using directive "@field or". Fields are still merged by default -
3496 equivalent to "@field merge".
3498 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3501 Fixed bug in zget for parameter ExtendedServicesResponse.
3505 --- 1.8.6 2002/03/25
3507 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3509 Client displays USR.1:SearchResult-1 (hits per term).
3511 Additional Search Info for search in Generic Frontend Server.
3513 Fixed CCL parsing of "field=s".
3515 WIN32 installer - using the excellent NSIS software from nullsoft.
3517 Fixed CCL parsing of "field = - <number>".
3519 Added function yaz_marc_decode that decodes MARC for line mode
3520 display or XML (similar to that used by JZKit).
3522 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3523 Z39.50. But ISO/ILL was, however.
3525 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3526 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3528 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3529 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3531 --- 1.8.5 2002/02/03
3533 New YAZ client features: Command completion and new commands:
3534 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3535 Code provided by Jacob Poulsen.
3537 New call oid_trav, that visits all registered OIDs via callback.
3539 Function ZOOM_record_get now returns const char pointer rather than
3540 void pointer. It saves a lot of type casts.
3542 For YAZ client, command "auth" now allows you to set authentication
3543 in IdPass style. It is enabled when three tokens are given - order
3544 is user, group and password.
3546 Fix memory leaks in MARC record handling for ZOOM.
3548 New option for YAZ client, -k <kilobytes> that sets
3549 maximum record size. Similar to -k option for generic frontend
3550 server and yaz-ztest.
3552 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3554 Prefix query parser reports "fail" when bad attribute set is given.
3556 Fix in MARC decoder. Proximity logging. Fix for attribute set
3557 in scan handler for server. Patches by Shigeru Ishida.
3559 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3562 Configure option --with-openssl=<dir> now works when a directory is
3563 specified. Patch provided by Morten Bogeskov.
3565 New option for YAZ client, -u <auth>, that sets authentication.
3567 ZOOM fix: error information was sometimes "missing", since error
3568 was cleared/reset too when it shouldn't.
3570 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3572 --- 1.8.4 2002/01/04
3574 Scan for ZOOM API. New object ZOOM_scanset. New functions
3575 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3576 ZOOM_scanset_destroy.
3578 New ZOOM function, ZOOM_connection_last_event, that returns type
3579 of last event (such as "receive data", "send data", "apdu received",
3582 New ZOOM option, schema, that specifies schema for retrieval.
3584 New CCL feature. Qualifiers can be aliases for one or more
3585 other qualifiers (if more than one is given, OR is used).
3587 ZOOM uses named result sets if target supports it.
3589 Two new YAZ client commands: . (dot, which sources a script of YAZ
3590 client commands), and ! (to execute shell command.). Implemented
3593 Working on Debian packages.
3595 --- 1.8.3 2001/11/19
3597 YAZ client enables named result sets only if target supports it.
3599 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3601 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3602 with key="host" to get same result.
3604 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3605 Function Z3950_resultset_record(s) returns references to records
3606 "owned" by resultset. To become owner use Z3950_record_clone.
3608 Function z_ext_record handles Extended Services. Thanks to
3611 --- 1.8.2 2001/11/12
3613 CCL Parser fix: ignore token comma when dealing with and-lists.
3615 Documentation updates for COMSTACK.
3617 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3618 Changed prototype Z3950_records. For some functions, int parameters
3619 were changed to size_t.
3621 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3624 New MARC decode/display function, marc_display_exl, which properly rejects
3625 non-ISO2709 records. YAZ client uses it.
3627 --- 1.8.1 2001/10/29
3629 Fix bug: local attribute set wasn't set correctly in PQF strings.
3633 * Old Z39.50 codecs no longer supported.
3635 Added ZOOM C binding. See http://zoom.z3950.org/
3637 Renamed states for COMSTACKs to avoid confusion with events.
3639 Implemented cs_look and proper cs_rcvconnect.
3641 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3643 Configure detects POSIX threads on OpenBSD.
3645 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3646 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3648 When error is returned from present handler, non-surrogate diagnostic
3649 is returned in present response (and fetch handler is no longer called).
3651 * Minor adjustments to pquery parser (PQF). Token characters may be
3652 escaped by using backslash (C-style).
3654 PQF parser allows string attribute values to be specified. For @attr,
3655 non-numeric characters after the equal-sign are treated as strings
3656 (e.g. @attr 9=title).
3658 CCL trunction character may be defined (@truncation in file)
3660 * function zget_ExtendedServicesRequest sets waitAction to
3661 waitIfPossible (was wait).
3663 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3666 CCL operator names may be set in field definition files (CCL_bibset).
3667 See ccl/bib1 for an example.
3669 Fixes in ASN.1 compiler for C++ compatibility.
3671 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3672 and "op_or" to avoid conflict with C++.
3674 Fixed problem with GNU readline detection on Redhat 7.0.
3676 Added step-size for Scan backend handler.
3678 Fixed bug that made the frontend server crash when no attribute
3679 set was specified for scan.
3681 Front-end server automatically switches to original working directory
3682 when installed as an NT service. Previously -w had to be specified to
3685 Added extended attributes for retrieval module (data1), so that data1
3686 records carry d1_readXML/SGML attributes. d1_read also supports
3687 null-data rules ( <tag/>)
3689 On UNIX when POSIX threads are available, a separate library libyazthread
3690 is created. Programmers should link with that library and the yaz library
3691 when using threads. The reason for the split was that some applications
3692 on Linux, such as Apache, doesn't work well when using shared objects that
3695 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3696 (or any frontend server) in SSL mode by specifying ssl: followed by
3697 address. Only tested on UNIX.
3699 Added feature for CCL module. Virtual structure s=al or s=ol generates
3700 and-list and or-list respectively instead of phrase search.
3704 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3705 log_mask_str. This was done to avoid name conflicts with other libraries
3706 (such as other PHP extensions).
3708 Added raw OID member for preferred record syntax (request_format_raw)
3709 and returned record syntax (output_format_raw) for backend fetch method.
3711 Config file yaz-config now accepts options so that it returns specific
3712 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3714 Shared library support for UNIX using GNU libtool.
3716 * Modified backend interface. Request/Response struct's replaced by
3717 one read/write C struct. For example bend_fetchrequest and
3718 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3719 Every handler - even search has to be registered in bend_init
3720 handler. This means that the YAZ library no longer refers to
3721 external functions and it makes it possible to make the whole
3722 thing a single DLL/SO.
3724 Added Segment handler for backend server.
3726 Added Zmbol/Zebra administrative functions to YAZ client.
3728 Threaded frontend server on UNIX (when POSIX Threads are available).
3729 Starting the server with option -T enables multi-threading.
3733 Added configure option --enable-comp/disable-comp to control use
3734 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3735 located in sub directory asn.
3737 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3738 in ${exec_prefix}/bin along with the other programs yaz-client and
3741 GNU automake used to maintain makefiles.
3743 Added several OID's.
3745 Changed retrieval module so that we can load records with no abstract
3746 syntax defined. Tagpaths in these records are fully composed of string
3749 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3753 On UNIX, the generated makefile now supports a proper 'make install'.
3754 The prefix can be set via GNU configure to set the install location
3755 (default is /usr/local).
3757 * YAZ programs client and ztest were renamed to yaz-client and
3758 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3759 locations, such as /usr/bin,/usr/local/bin,etc.
3761 * YAZ Header files were moved from include to include/yaz. YAZ Header
3762 files are referred to as include <yaz/log.h> rather than <log.h>.
3763 The YAZ include path (-I ..) is therefore the same as before. Programmers
3764 should update their #include statements or use -Ipath/include/yaz
3765 instead. The main motivation for doing this change is that YAZ header files
3766 can be installed in "standard" locations /usr/include,/usr/local/include
3767 without introducing conflicts, since ALL YAZ header files are stored
3768 in subdirectory yaz (under /usr/include for example).
3770 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3771 rather than project/workspace files. We switched because project files
3772 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3775 Changed name of logging function, logf, to yaz_log, to prevent name
3776 clash with some math-log functions. The YAZ header log.h defines logf
3777 to yaz_log (#define) so there should be no incompatibilities by this
3780 Added bend_start/bend_stop handlers for server. These handler are
3781 called on start/stop of server. For windows they are called whenever
3782 a service is started/stopped.
3784 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3785 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3786 in util/yc.tcl. The auto-generated C code structures are, in a few
3787 cases, incompatible with the old decoders. There are differences in the
3788 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3789 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3790 The preprocessor variable ASN_COMPILED is defined when the compiled
3791 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3792 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3793 wish to use the old encoders/decoders you can specify --disable-yc
3796 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3797 version so that it supports both new - and old version of DB Update
3799 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3800 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3801 change. The name parameter can be set to 0 in which no name is specified
3802 for the construction. The macros odr_implicit and odr_explicit sets name
3803 parameter to zero for the construction involved. New macros
3804 odr_implicit_tag and odr_explicit_tag are similar to the others,
3805 except that a name parameter is added. For programmers' that don't use
3806 ODR they probably only need to change the call to z_APDU and z_External.
3808 Added access control facility by interfacing the TCP wrapper library.
3809 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3810 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3811 name of the daemon and enables the access control as specified in
3812 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3814 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3815 den Dool <H.M.vdnDool@kub.nl>.
3817 Added reference ID parameter to most functions in server API - refer
3818 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3820 Changed name of ccl library to libccl.a (was ccl.a).
3822 Fixed bug in decoder for Explain (Category TargetInfo).
3824 Added support for GNU readline in client. Thanks to Jacob Poulsen
3825 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3827 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3828 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3829 IMPLEMENTATION! This change was made to the development version before
3830 the ZIG decided to retract the amendment. If any users MUST be
3831 compatible with the original Update definition, PLEASE CONTACT US, and
3832 we will include a separate definition corresponding to the old Update
3833 ES. Note that because of the change to the ASN.1 of the
3834 TaskPackageRecordStructure we cannot define a single structure that
3835 will support both versions.
3837 * Added const modifier to buffer parameter for some ODR/BER encoding
3838 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3839 completeWAIS, odr_dumpBER.
3841 Fixed bug in client.c which caused a crash when a scanResponse didn't
3842 contain positionOfTerm.
3844 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3845 * will cause an error in a client if a non-YAZ target sends both a
3846 * list of Scan entries and non-surrogate diagnostics.
3848 Retrieval module enhancements. Tag sets may be typed in the reference
3849 to it. From the .abs-file the "tagset" directive takes a third optional
3850 integer type for the tag set referenced. From a .tag-file the "include"
3851 directive takes a third optional type as well. The old "type" directive
3852 in the tag set itself is still recognized but acts as the default type
3855 Backend interface change. Individual Scan terms returned from bend_scan
3856 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3857 in include/backend.h.
3859 Retrieval module enhancements. Multiple tag sets and attribute sets may
3860 be specified in abstract syntax specs. Revised the error/warning for
3861 logging messages reported by the retrieval module when reading the
3864 Object Identifier system (oid_..) changed. The API is backwards
3865 compatible but the oid-routines now allocates new OID's when needed.
3866 Raw OID's may be specified in oid_getvalbyname.
3868 YAZ now uses GNU configure to generate Makefile(s).
3870 * Minor changes in some of the member names of DeleteResultSetRequest and
3871 DeleteResultSetResponse. See include/proto.h.
3873 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3874 and added member 'languages' in TargetInfo (which was missing).
3876 Changed the way attribute sets are handled in the retrieval
3877 module. These are now cached, just like the abstract syntaxes
3880 Changed YAZ so that it links with compiled ASN.1.
3882 Added Explain-schema definitions and mapping routines. The following
3883 Explain categories have been implemented: AttributeDetails,
3884 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3886 Fixed minor bug in Windows version of Server Library.
3888 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3890 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3892 Added EXTERNAL: UNIverse Resource Report (non-standard).
3894 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3895 ENUMERATED and SET OF.
3897 * Added 'const' to some of the char pointer arguments for the
3898 functions, data1_read_node, data1_getelementbytagname,
3899 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3902 Fixed bug in data1_insert_taggeddata - the last_child member of
3903 parent wasn't initialised.
3905 * Changed data1_read_record and data1_read_node so that the supplied
3906 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3907 doesn't refer to any parts of the "SGML"-buffer.
3909 Fixed bug in server library (Windows version of statserv_remove).
3911 * Changed code so that it compiles as C++. The type definition
3912 of Odr_fun which is a member of Odr_arm was changed. The result is,
3913 that an explicit typecast is needed for the fun pointer when
3914 using Odr_arm - as in:
3915 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3917 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3919 Implemented the new structured date and time definition as approved
3920 by the ZIG. Added schemaId element to the specificTag in Espec-1
3921 (also approved at the last ZIG). Thanks to RVDM.
3923 Added some Object identifiers (RVDM).
3925 Changed the Update Extended Service (RVDM).
3927 Added command "refid" to client which specifies referenceId for
3928 the following requests.
3930 Implemented extended service handling for server. See ztest.c
3931 for an example as well as backend.h. New handlers are registerd
3932 in the Init handler.
3934 * Changed interface for sort in server.
3936 Added new members to statserv_options_block. It allows a server
3937 to read options from another source than just the command line. Thanks
3938 to Charles Woodfield.
3940 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3941 renamed to zboolean. Some C++ compilers complained about the name.
3943 Minor changes to gils.abs. Added index 's' (sort) on title
3944 and date/time-last-modified.
3946 --- 1.4pl2 1998/1/30
3948 Fixed bug in server library regarding inetd mode (-i). This bug
3949 was introduced by release 1.4.
3951 --- 1.4pl1 1998/1/29
3953 Added sort facility in client and backend server interface.
3955 Fixed problem with dependencies in Makefile(s).
3957 Fixed bugs for encoders/decoders of extended services and
3960 Implemented sub-tree feature for schemas. Sub-trees are
3961 referenced in *.abs-files. See explain.abs for an example
3962 of the use of this feature.
3964 Modified bib1.att; local attributes for ANY didn't include
3965 ANY itself (only affects use of the retrieval module).
3967 Fixed bug in plain SGML reader in function data1_read_node:
3968 tags with prefix "var" was incorrectly interpreted as variants.
3970 Added feature "sub-schemas" to enable references to - and definitions
3971 of - group of elements.
3973 * Removed member parent from type data1_element (in data1.h).
3975 Implemented function odr_nullval() that returns the value of
3978 * Removed member num_children from data1_node (in data1.h).
3980 Made NT service interface part of the server library. The
3981 function statserv_main uses the NT service when required and
3982 calls the statserv_start / statserv_close routines.
3984 Routine zget_SearchRequest and zget_PresentRequest fills
3985 resultSetName/Id member with "default" instead of "Default".
3987 Fixed memory leak in server. Request queue member wasn't freed.
3989 Fixed nmem_exit so that memory is freed.
3993 Revised the CCL parser utility to be thread safe.
3995 Added function, oid_ent_to_oid, to replace the function
3996 oid_getoidbyent, which is not thread safe.
3998 * Added nmem_init and nmem_exit to initialize and release
3999 NMEM resources. Function nmem_init should be called once in the
4000 initial thread before NMEM/ODR is used. statserv.c and client.c
4001 have been changed accordingly. The change was necessary to make
4002 NMEM thread safe. The NMEM memory pool is shared amongst threads
4003 in a process. Unix-based applications will still work fine without
4006 Added NT Services interface for the the Z39.50 (statserv) Server.
4007 Refer to the ztest.c source on the usage.
4009 Windows 95/NT port using MSVC5.0. Project files are included in the
4012 * Defined new 'global' handle for the retrieval (data1) system. The
4013 new handled, data1_handle, describes the state of the data1 system.
4014 This handle is passed as first argument to virtually all
4015 data1 related routines. The functions data1_create and data1_destroy
4016 creates and destroys a data1 handle respectively.
4018 Added ODR encode stream member to all backend request structures
4019 init, search, scan etc. This stream should be used to allocate all
4020 memory used for the response when thread safe operation is needed.
4022 Changed the comstack utility, cs_addstr, to be thread safe. The
4023 returned hostname string returned by the function is now part the
4026 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
4027 function. The cs_straddr takes a COMSTACK handle as argument, so this
4028 function must be used after cs_create and before bind/connect.
4029 This function is thread safe.
4031 Moved test server to 'ztest' directory - generic server code still
4032 in 'server' directory.
4034 Made prefix query (pquery.c) utility thread safe.
4036 Added new function modifier YAZ_EXPORT to 'export' public DLL
4037 functions when using windows (see include/yconfig.h).
4039 Added definitions to the OID database (util/oid.c) (RVDM).
4041 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
4043 Added call to ccl_rpn_delete in client program.
4045 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
4046 release of RPN structure.
4048 Added support for C++, headers uses extern "C" for public definitions.
4049 With input from RVDM.
4051 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
4052 Thanks to Ronald van der Meer (RVDM).
4054 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4056 Added support for private extensions to the OID database
4057 (oid_setprivateoids()). Thanks to RVDM.
4059 Added optional, physical ANY (key replication)
4061 Fixed null-reference problem in GRS-1 output filter.
4063 Proximity operator added to Prefix Query Format (PQF).
4065 In test client command "base" accepts multiple databases.
4067 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4071 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4073 Smallish bug-fixes in the new encoders/decoders (explain).
4075 Bug fixed in DeleteRequest.
4077 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4079 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4081 Added SOIF syntax (using private OID for now) to retrieval module and client.
4083 Added Update extended service.
4085 Added SearchResult-1 additional info structure.
4087 Added optional CCL (ISO8777) interpreter as separate module. Available
4090 --- 1.2 1996/6/10 (1st anniversary release)
4092 Added Summary record syntax. Lightly tested.
4094 Added OPAC record syntax. Untested.
4096 Added ResourceReport service encoders/decoders. Untested.
4098 Fixed bug in z_Unit - wrong tagging on unitSystem.
4100 Fixed bug in the DiagRecs decoder.
4102 Added options for max PDU size and session timeout to frontend-server.
4104 Added documentation of query-language parsers and other supporting utilities.
4106 [frontend-server] Added Attribute set to the bend_scanrequest API.
4108 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4109 surrogate diagnostics were generated.
4111 [retrieval] Allow multiple local values for attribute.
4113 [retrieval] Allow multiple attributes per element in .abs files. index type.
4115 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4117 --- 1.1pl2 1996/4/10
4119 Minor changes, mostly specific to Zebra's requirements (retrieval)
4123 Repaired bug in frontend server when running multiple listening
4124 endpoints in dynamic mode.
4126 z_External() now won't break if a known, ASN.1 value comes encapsulated
4127 in an octet-string. The value will pass through unmodified in an Odr_oct.
4129 Added a bit of code to the demo client to decode & display
4130 ASN.1-structured records represented in the octet-aligned branch of
4131 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4133 Added z_ext_getentbyref() to the ASN module. Doc updated.
4135 * Completed the SCAN definition in the ASN module. This may break SCAN
4136 code based on older YAZ-versions at compile-time. The fix is easy -
4139 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4140 under the SCAN definition. Remember to initialize this, server-people.
4142 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4143 that this does not extend to ODR and ASN.
4145 Comstack allows insertion of established socket (primarily for
4146 inetd-operation of servers). Doc updated.
4148 Front-end server can now start from the inetd in TCP mode. Doc
4151 --- 1.0pl4 1996/1/24
4155 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4156 the rank and record number.
4158 Adjustments to the frontend server.
4160 Fixed diagnostic BER dumper. It ignored the file argument.
4164 Various changes to retrieval module.
4166 Changed the union discriminators of the protocol files from enums to
4167 ints paired with #defines.
4169 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4172 *Changed operator in the RPN structure to 'roperator', again to avoid a
4175 Fixed problems in Explain decoders/encoders.
4177 --- 1.0pl2 1995/12/6
4179 Memory bug in log module fixed.
4181 --- 1.0pl1 1995/12/5
4183 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4185 Bug in Explain DatabaseInfo module fixed.
4187 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4191 The shift to v1.0 signals that we now consider the *core* functionality
4192 of YAZ reasonably stable (the core being more or less equivalent to
4193 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4194 tested (Explain not at all - though that will happen soonish).
4196 Minor changes to code to support Windows port.
4198 Various minor changes after we're getting to use GRS-1 & co. more.
4200 Added Espec-1 format.
4202 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4203 of the protocol and it cannot be selected when encoding (maps into 'string'
4204 when decoding). Needed to talk to some servers.
4206 Demo client can request simple element set names.
4208 Added Diagnostic Format encoders/decoders.
4210 Added simple Close handling to frontend server (no hooks for resource
4211 reporting yet), and demonstration client.
4213 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4215 --- 1.0b3 1995/08/24
4217 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4218 handled incorrectly when records were requested in the searchResponse. This
4219 will only affect you if you use the frontend-server.
4221 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4222 Test-client will ask for and print GRS1. Ztest will return dummy records
4225 Added Explain encoders/decoders to the service-level API. Untested.
4227 Added Extended Services: Item Order encoders and decoders to the Service-
4228 level API. Untested. We could use a recent copy of the pertinent bits
4229 of the ILL protocol to add those bits.
4231 Added diagnostic format 1 encoders/decoders to the service-level API.
4234 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4235 odr_cons.c, which causes a more correct output.
4237 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4238 was always set to 0 when no records were requested in the searchRequest.
4240 * Added better external-handling. This shouldn't harm old code that
4241 *encodes* externals. It can break code that looks for a
4242 'single-ASN1-type' representation, since those types that are known
4243 are now decoded immediately. Look at the SUTRS sample code in
4244 seshigh.c and client.c. Documentation updated.
4246 Handling of structured records in bend_fetchresponse. Length -1 marks
4247 structured record, type is deduced from format field.
4249 --- 1.0b2 1995/06/27
4250 Fairly quick maintenance release to add SUTRS support.
4252 Fixed handling of SUTRS records in the demonstration client.
4254 * Added format field to the bend_fetchrequest and bend_fetchresponce
4255 structures of the backend API (frontend server). When the record is
4256 returned, the value of the format field is mapped to an OID. The
4257 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4258 of the record. The special value VAL_NONE in the bend_request means
4259 that no specific format was requested by the client. Documentation
4260 updated accordingly. Test server (ztest) will return a fixed dummy
4261 SUTRS record if your client requests SUTRS.
4263 Documentation updated accordingly.
4265 You can now set external libraries and RANLIB support in the top-level
4269 First public release.
