3 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
4 Introduce cs_create_host2 which returns if connection should be
5 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
6 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
8 Fix http proxy fails with yaz-client YAZ-824
12 Fix 0 ptr reference for OPAC records from XML YAZ-822
16 Extend yaz daemon facility to assist int log rotation YAZ-818 YAZ-819
20 record conv: 'select' return org record if no x-path match YAZ-814
22 retrieval: pick matched element-set rule YAZ-813
24 Fix crash in record conv rule 'select' YAZ-812
28 record_conv: selection by X-Path YAZ-811
29 That's a new step in record conversion system (<select path=".."/>)
31 Document record render parameters for ZOOM - including base64
35 Fix application/x-www-form-urlencoded + empty YAZ-810
36 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
37 and empty content was supplied.
39 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
41 Fail hard if Bison is not found and is needed YAZ-808
45 Enable YAZ backtrace for programs YAZ-802
47 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
48 Libxml2 2.9.2, Libxslt 1.1.28.
50 Fix daemon: parent process stops before child YAZ-806
51 Try to fix the situation where parent process stops before
52 child has acknowledged it .. SIGUSR2 back!
54 daemon: log message when keepalive stops.
58 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
59 would make yaz-marcdump crash when from-character set was issued.
63 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
64 New function yaz_enable_panic_backtrace which enables backtrace
65 handler for current process. The handler will call backtrace always,
66 then gdb to provide as much detail as possible.
70 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
71 and ZOOM record render will inspect leader 9 and switch to UTF-8
72 (Unicode) if that holds 'a'. This changes behavior, but is considered
73 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
75 Fix cs_put may reconnect if send fails. YAZ-798
79 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
83 Extended comstack with outgoing IP YAZ-795.
84 For cs_create_host + cs_create_host_proxy the vhost may be followed
85 by a outgoing host/IP. Separator is blank.
89 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
90 linker error with yazpp on Windows.
94 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
96 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792
98 0 ptr reference in handling Solr response with error YAZ-791
100 Fix annoying warning about wrbuf_putc on newer GCC YAZ-789
102 Fix documentation about --installa option YAZ-788
106 daemon: properly report when receiving SIGUSR2 from child YAZ-785
110 xmalloc: throw assert for clearly invalid calls to malloc and
111 improve diagnostics YAZ-783 YAZ-784
115 Stop building debs for Ubuntu raring, quantal, oneiric.
117 CCL YAZ-781: for multiple use attributes in a specification the
118 generated RPN will perform @or on each term.
119 For spec: term u=31 u=1016
120 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
122 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
124 CCL YAZ-779: combo qualifier should allow for forward references
126 Fix buildconf.sh, automake too old on centos5 YAZ-778
127 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
128 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
129 accepts it without a warning.
133 GFS: client_query_charset conversion YAZ-777
134 This is a feature for Z39.50 clients that sends queries that are not
135 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
136 encoding given to UTF-8.
138 Echoed SRU arguments support YAZ-776
139 This is achieved with new function yaz_srw_get_pdu_e.
141 ZOOM: expire times set for redis/memcached YAZ-772
142 For both redis and memcached option --expire=seconds sets expire
143 time for a result-set/search. Default time is 600 seconds (10 minutes).
147 No [rest of output is omitted] limit for yaz_log YAZ-774
149 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
151 For ICU testing, pass -o to yaz-icu. This will test the
152 icu_iter_get_org_info function.
154 Fix null ptr reference for freeReplyObject YAZ-773
158 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
160 RPM: do not build with libmemcached support. The libmemcached library
161 on CentOS 5/6 does not work reliably for us (redis to the rescue).
163 configure: only allow libmemcached version 0.40 or later. That's the version
164 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
165 that's not an option, consider redis.
169 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
171 Fix zoom+memcached: present request out of range YAZ-767
175 CCL: add new qualifier r=omiteq which will omit relation=equals
176 for ordered relations. This should be used in combination with either
179 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
181 Solr: simplify yaz_solr_decode_response
183 Solr: use different local var for string manipulation
185 Solr: Get rid of hardcoded limit of extra_args
187 Solr: encode lucene query type YAZ-736
188 Make sure the queries are treated as traditional "lucene", because that's
191 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
195 Build packages for Ubuntu Trusty Tahr 14.04 LTS
197 wrbuf_cstr: fix off by one error.
199 wrbuf_buf: make it always return non-NULL
200 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
204 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
206 zoomsh: offer option -a apdulog
207 As we're used to from yaz-client and GFS based servers.
209 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
210 existing setting apdulog takes effect.
212 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
217 Add re-entrant CQL/Solr/RPN query conversion functions.
218 The re-entrant functions are: cql_transform_r,
219 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
220 These have same functionality as cql_transform,
221 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
222 return the additional infomration as WRBUF to make them re-entrant.
224 Remove CQL to Solr conversion and base solr_transform_t on
225 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
226 data structure as cql_transform_t.
228 cql2pqf utility allows RPN to Solr conversion
230 Fix assert in ZOOM when http connect fails YAZ-757
232 --- 5.0.22 2014/04/09
234 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
236 wrbuf_cstr: make it thread safe YAZ-753
238 yaz_log_init_file may take fd=<no> to open log file at the FD given.
240 --- 5.0.21 2014/03/21
242 Offer new utility function zget_AttributeList_use_string.
244 New conversion step, solrmarc, for record conversion module.
246 --- 5.0.20 2014/03/13
248 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
249 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
252 --- 5.0.19 2014/03/10
254 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
255 The standalone ZOOM sort was completely broken since 5.0.13.
257 ZOOM: generate event Connect rather than None for partial connect
258 (in fact getaddrinfo resolving).
260 ZOOM: only supply clientIP for InitRequest. Rather than for all
263 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
265 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
266 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
267 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
269 New "Facets" section in the documentation.
271 --- 5.0.18 2014/02/27
273 Call exsltRegisterAll in yaz_init_globals, so that all applications
274 using YAZ will have EXSLT things enabled.
276 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
278 Update various URLs to the re-organized SRU pages at LoC.
280 --- 5.0.17 2014/02/26
282 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
283 introduced in 5.0.12.
285 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
286 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
287 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
290 --- 5.0.16 2014/02/25
292 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
294 --- 5.0.15 2014/02/24
296 Fix gcrypt not properly initialized YAZ-740.
298 --- 5.0.14 2014/02/19
300 Describe memcached option for ZOOM.
302 ZOOM: throw present request out of range again YAZ-739
303 Was removed in YAZ 5.0.13.
305 --- 5.0.13 2014/02/18
307 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
308 with localtime_r when threads + fork is used (such as Metaproxy).
310 yaz-config: quote some RHS values (that might include blanks)
312 zoomsh: shows SearchResult-1
314 zoomsh: sortby command
316 zoomsh: use proper list of connections and result sets YAZ-725
318 Avoid yaz_log in sigterm handler for GFS YAZ-737
319 Logging is still performed, but outside sig handler.
321 New ZOOM C feature: result-set caching with memcached. Example:
322 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
324 Remove SSL via OpenSSL support YAZ-732
325 Also deprecate two functions from comstack that aren't working with
326 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
328 Revert "Bison: use %name-prefix directive rather than -p option"
330 --- 5.0.12 2014/01/22
332 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
334 SRU GET/Solr base URLs may hold additional ?args YAZ-729
335 ZOOM option extraArgs already does this, though. It seems useful
336 when dealing with Solr targets to limit by filter, eg.
337 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
339 Remove #fragment for HTTP request encoding YAZ-730
341 Doc: Update list of DLLs/LIBs
343 Doc: update href link to Unix utils and Git.
345 --- 5.0.11 2014/01/15
347 ZOOM: fix "lost connection" problem with servers that uses both squid
348 and another proxy behind it that returns Location headers with relative
351 zoomsh: do not use readline for stdin (no tty) YAZ-724
352 Just use fgets in that case. If the user hits Ctrl-D a new-line
355 zoomsh: empty command ignored YAZ-723
356 rather than performing exit of zoomsh.
358 yaz-url utility offers option -v to enable verbose mode.
360 yaz_url uses yaz_check_location and offers verbose mode.
362 Add new function yaz_check_location.
363 This function gets an absolute URI from Location (HTTP redirect).
365 cookie API: introduce yaz_cookies_reset
367 Update cql.y for newer bison YAZ-720
368 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
369 longer supported. Instead one must use %lex-param and %parse-param .
371 --- 5.0.10 2014/01/09
373 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
376 rpn2solr: support truncation left(2), left&right(3) YAZ-718
378 Mention SRU version 2.0 in yaz-client man page.
382 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
387 Make cs_parse_host public.A
389 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
390 introduced in YAZ 5.0.6.
394 Fix buffer corruption for yaz-ztest record fetch.
398 Allow yaz-ztest to return user-defined records (one record per file).
399 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
401 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
402 Use the stream write instead of odr_printf which has a 4K tmp buffer.
404 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
408 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
409 can read and write this format. For record format JSON, yaz-ztest returns
410 MARC-in-JSON records.
412 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
413 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
417 Improve error reporting for ICU chains YAZ-707
418 Report config element+rule when ICU status is "failure".
420 ZOOM: stop fetching if present response has no records YAZ-710
421 Some targets return less records than their hit count would suggest.
422 This prevents ZOOM from continuing to fetch records if any present
423 response has 0 records in the response.
425 Ensure that GFS calls exit if any listener fails YAZ-710
426 Before, if XML config was in use, it would start the default
431 yaz-ztest: -V shows version (like yaz-client -V)
433 New iconv encoding: danmarc YAZ-692
435 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
437 daemon: only wait for immediate child rather than all children. YAZ-704
439 yaz-client: fix setting of SRU record schema. If scheme was unset, it
440 could lead to invalid memory reference.
444 yaz-ztest returns schema for MARCXML test records. SRU require that
445 recordSchema for records.
447 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
448 instead of non-surrogate diagnostic. This is a per-record failure.
450 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
451 may refer to multiple listeners now. Attribute listenref is a comma separated
454 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
455 option is given for GFS, the dirname of filename (for -f) is used
456 as prefix for options such as cql2rpn, ccl2rpn, etc.
458 Content-Type charset fixes YAZ-701 . Do not inspect charset in
459 Content-Type header for SOAP when decoding SRU. The payload (XML)
460 itself tells what encoding it is. In response, never supply encoding
461 in Content-Type. The response payload (XML) tells what it is (with no
462 encoding in XML it's UTF-8).
464 HTTP decoding: allow blanks in URL paths YAZ-700
468 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
469 and facets. Ensure recordData and recordSchema are always present in
470 record element, because they are required.
472 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
475 Simplify in a lot of places using odr_strdupn.
477 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
481 Increase various buffers in GFS's statserv_options_block
482 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
483 This change makes many type-casts redundant, and, thus simplifies code.
485 Remove last bits of WAIS support.
487 Remove member 'size' from Odr_oct.
489 Slim down the public part of 'struct odr'. Most elements are not part
490 of struct Odr_private.
492 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
493 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
494 In particular facets are supported in both client - and server side.
495 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
496 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
497 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
498 both request/response). This is what a search handler in the GFS
499 will see (regardless of whether operating in SRU mode or Z39.50).
501 Changes to the srw.h (SRU/Solr) definitions include:
502 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
503 (char*), which replace union query and query_type (int). This is because
504 SRU 2.0 supports a queryType parameter. This also means that, to carry
505 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
506 x-pquery=PQFstring (extention parameter). The extension parameter
508 - New element, packing, that has information about SRU
509 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
511 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
513 New element, packing, in Z_SRW_explainRequest.
515 New elements in Z_SRW_scanRequest, queryType and scanClause.
516 These replace query_type and scanClase untion. This is similar to what
519 --- 4.2.69 2013/10/01
521 GFS: log when closing down - at least SIGTERM YAZ-684
522 Also change formatting WRT PID logging a bit.
524 Improve display of MARC records with multi-byte subfield IDs YAZ-695
525 In some rare cases subfield identifiers are multi-byte characters.
526 This will try to deterime length of those and split accordingly.
527 This affects display in line mode as MARCXML/MarcXchange. The encoding
528 of ISO2709 is the same.
530 Change inp argument to const for yaz_read_UTF8_char.
532 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
534 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
536 Better check of marc leader info YAZ-691
537 Problem is that some systems generate MARCXML/MarcXchange with
538 funny headers. These will not work if encoded as ISO2709.
539 Some tests produce new output, due to updated warning messages
541 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
543 yaz-client: display MAB records YAZ-689.
544 Thanks for Heiko Jansen for this patch.
546 New utility z_get_HTTP_Response_server which allows both HTTP server name
547 and HTTP server URL to be given in response.
549 Debian: do not depend on obs tcl8.3.
551 Debian: do not depend on obs libicu36-dev.
553 --- 4.2.68 2013/09/23
555 GFS: pass additionalSearchInfo to search memeber search_input if
556 given. Otherwise pass otherInfo. Request for facets and other search
557 related things will be passed there in future versions of YAZ.
559 New ZOOM setting, authenticationMode, which allows authentication
560 paramters to be encoded in the URL rather than via HTTP Basic auth.
563 rpn2solr: fix nested AND/OR handling. YAZ-685
565 Add comparison routines for some Z-types, such as NamePlusRecord,
566 RPNQuery, Query, RecordComposition and OtherInformation.
568 --- 4.2.67 2013/09/19
570 Don't decode MAB as MARC. Just like we don't attempt to decode
571 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
573 CCL: allow quoted terms for date ranges. YAZ-681
575 Introduce ccl_parser_qual_search. This function makes old function
576 ccl_qual_search, from YAZ 2, available again.
578 Add yaz_facet_list_to_wrbuf. YAZ-683
580 --- 4.2.66 2013/09/11
582 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
583 schema was given for search. YAZ-675
585 Add Solr date range searches. YAZ-621
587 --- 4.2.65 2013/08/22
589 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
591 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
593 ISO2709/MARC parse most octet aligned records; not just those that
594 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
595 MARC parse more records instead of just dumping as is. YAZ-670
597 ZOOM: proper caching for variations of record schema. YAZ-671
599 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
601 --- 4.2.63 2013/07/17
605 --- 4.2.62 2013/07/11
607 New utility z_get_HTTP_Response_details - an extended version of
610 New utility yaz_url_get_error which returns error message of last
611 failed yaz_url_exec call.
613 yaz-url and url functions: allow max HTTP redirects to be controlled.
615 New functions yaz_file_glob2, yaz_xml_include_glob.
616 These functions takes a flags parameter, which, for now only controls
617 whether to fail inclusion of a non-existing file (without glob
618 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
620 --- 4.2.61 2013/06/20
622 For MARC XML parsing, allow record without leader. A fake/default leader
623 is inserted and a warning is tagged with the record.
625 ICU: fix leak in in icu_iter_get_org_info.
627 --- 4.2.60 2013/06/14
629 ICU: fix bug in icu_iter_get_org_info (un-init variable).
631 --- 4.2.59 2013/06/11
633 Implement z_HTTP_header_remove.
635 --- 4.2.58 2013/06/11
637 ICU: Disallow 0 ptrs for some ICU string utilities.
639 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
640 returns original tokens (before normalization).
642 CCL: avoid z39.58/regex truncation when not needed. Apply only the
643 conversion of those masks, when absolutely necessary.
645 CCL: configurable masking character - @mask. Default masking character
648 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
649 full response anyway, so a Transfer-Encoding header will obstruct the
652 --- 4.2.57 2013/05/15
654 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
655 picking a socket. Problem is that some systems has IPV6 support, but
656 we can't create sockets for them, so we pick AF_UNSPEC first.
658 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
659 use content_len to determine resulting Content-Length in HTTP response
660 and NOT Content-Length supplied in headers by user.
662 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
663 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
665 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
668 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
669 with big endian and unsigned char (by default).
671 --- 4.2.56 2013/04/26
673 Fix yaz-client connect (crash in 4.2.55).
675 --- 4.2.55 2013/04/26
677 Fix proxy/host problem for ZOOM that could occur if unix sockets
680 New Debian package libyaz4-dbg.
682 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
683 differently in tcpip_close.
685 --- 4.2.54 2013/04/17
687 Windows installer of YAZ includes YAZ4J as a component.
689 CQL: allow "extra terms" again, by default. Thus, the CQL parser
690 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
691 and earlier. CQL parser may operate in strict mode where queries
692 not conforming to the standard BNF are rejected (syntax error).
693 Whether the CQL parser operates in strict mode is controlled with
694 cql_parser_strict . Strict mode enabled with option -S for utilities
695 cql2pqf and cql2xcql .
697 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
699 --- 4.2.53 2013/04/10
701 New charset, MARC-8c, which is like MARC-8 but allows control characters
702 0x01 through 0x1F, except ESC to be passed through verbatim.
704 Fix a problem with duplicate sub field character in MARC output. Problem
705 happened only when output was MARC-8 encoded.
707 --- 4.2.52 2013/04/03
709 yaz-ztest: Use hash for fake hit count. Before, random number was used.
710 This is problematic for unit tests using yaz-ztest. This patch also makes
711 a hash for CQL queries. For RPN, any term with a leading digit will be
712 treated as pseudu hit count (to force any particular hit count by a client).
714 yaz-ztest: return unique MARC dummy records. Beyond record offset
715 24, the author surname is patched with offset to make all records
718 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
719 on system wide default (/proc/sys/net/ipv6/bindv6only).
720 @4 binds to IPV4 only. @6 binds to IPV6 only.
722 Update CQL API documentation a bit
724 CQL: don't accept extra terms for queries. Makes the CQL parser
725 stricly conformant to the standard.
727 --- 4.2.51 2013/02/12
729 GFS: scan handler gets extra_args from request and may return extra
730 response data . That's for SRU only.
732 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
734 --- 4.2.50 2013/01/30
736 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
738 OPACXML: sync spelling of availabilityDate in XML to that of Schema
739 opaxxml.xsd. The schema had the correct spelling of this member always.
740 The ASN.1 was mis-spelled and still is (API change) - we are
741 not changing this. However, the OPAC to XML conversion had yet
744 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
747 New function, z_ext_record_oid_nmem, which is similar to
748 z_ext_record_oid but takes NMEM rather than ODR
750 --- 4.2.49 2013/01/18
752 ICU: New conversion element 'join' which joins tokens into one
753 with a custom character given by rule attribute.
755 --- 4.2.48 2013/01/10
757 New GFS search member: present_number. This is a hint to the
758 search handler how many records are going to be fetched immediately
759 following search. There's no guarantee that it's going to be the case,
760 since it depends on hit count (for Z39.50 piggyback) and whether errors
763 Make a few functions static (private). The functions getbyte_stream,
764 ungetbyte_stream and yaz_gets are now private. They were never declared
767 yaz-marcdump: exit(5) for serious decoding errors
769 ISO2709 decoding: be more picky WRT header
771 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
772 was only used as to indicate that next-result-set-position should be
774 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
775 Based on patch from Ashley Sanders.
777 Make some functions static/private in PQF parsing. Those functions were
778 never declared in a public header and so should not be in use by
779 applications based on YAZ.
781 --- 4.2.47 2012/11/23
783 ZOOM: special options to control APDU logging.
784 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
785 logging of APDUs until "saveAPDU" option is set again. If logging is
786 already enabled the effect is that current APDU buffer is cleared.
787 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
788 logging (default behavior on new connection).
789 The APDUs sent/received can be obtained by using
790 Using ZOOM_connection_option_get(c, "APDU") or
791 ZOOM_connection_option_getl(c, "APDU", &l).
793 GFS: relay implementation_version from backend
794 From 3.0.40 and later, implementation_version from backend was
795 not used in init response at all.
797 --- 4.2.46 2012/11/15
799 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
800 mode at all. Probably never did.
802 Make a new version of ztest.pem that, at least, is not expired.
804 --- 4.2.45 2012/11/13
806 Fix description of CCL directive 'case'.
808 More tight checking of form arguments (yaz_uri_to_array). Makes
809 YAZ better at rejecting big and/or bad POSTs.
811 SRU decoding does not report more than up to 10 invalid arguments.
813 rpn2cql: less quotes in generated terms. Semantics unchanged, but
814 it's prettier this way.
816 --- 4.2.44 2012/10/25
818 New utility yaz_decode_init_diag. Defined in proto.h.
820 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
821 given for unix local socket.
822 The COMSTACK string for doing so is:
825 unix:/myfile:tcp:localhost:9999/mybase
826 unix:/myfile:localhost:9999/mybase
827 unix:/myfile:http://fakehost/mybase
829 debian: Use dpkg-buildflags in build process.
831 --- 4.2.43 2012/10/19
833 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
834 global's SRU service uses a recordPosition scheme starting from zero.
835 First record's position should be one
836 according to the standard.
838 --- 4.2.42 2012/10/18
840 Allow more namespaces for SRU. This is to allow, for example, an
841 incorrect namespace returned from server
842 http://services.igi-global.com/sru .
844 Minor fixes for compilation on Windows.
846 --- 4.2.41 2012/10/11
848 daemon: log total number of bad signals from child on stop so that it
849 is more easy to spot problems with child worker processes.
851 retrieval: empty backend name attribute omits element set
852 from being used in retrieval.
854 --- 4.2.40 2012/10/04
856 Implement Solr sort strategy "solr", similar to sru11 sorting.
857 This will implement the correct parameters on Solr requst to do
860 --- 4.2.39 2012/09/28
862 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
865 MARC: Extra/missing indicator handled for MARCXML.
866 The indicator length is given in header and is the same for the
867 whole record. If attributes ind1, ind2 are missing, then content
868 character defaults to blank. Extra indicator attributes (beyond)
869 indicator length are treated as an error.
871 Reformat: delete trailing whitespace
873 --- 4.2.38 2012/09/17
875 MARC: fix non-ASCII characters for leader. This is to ensure we can
876 generate XML in UTF-8.
878 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
879 in one node with structure word.
881 --- 4.2.37 2012/09/04
883 yaz-json-parse: JSON output may be pretty printed by using option
886 Increase default value of max message for Z39.50 Init for GFS, ZOOM
887 and yaz-client. Old value was 1 MB. New value is 64 MB.
889 --- 4.2.36 2012/08/22
891 yaz-client: don't display bogus records from SRU servers. Some SRU servers
892 return more records than given by *maximumRecords*. Skipping those in
895 record_render: simplify buffer return handling and fix at least one bad
896 memory reference, that broke the test_embed_record sometimes.
898 Allow http://user:pass@host notation for yaz_url_exec.
900 zoomsh: allow shell command to be executed. Via the system(3) call.
902 yaz_poll: Allow num_fds == 0
904 yaz-client: fix bad encoding of "itemorder item". The itemorder
905 item <no> - command forgot to use length of encoded Item Request
906 package. Error present since YAZ 3.
908 yaz-ztest: fix bad usage of session handle. Bug was introduced when
909 result sets were saved (271a9c83).
911 SRU recordPacking: guess record packing in response rather than looking
912 at the recordPacking element which, OF COURSE, changed semantics in SRU
915 Decode SRU 2.0 responses. The official namespace for responses, according
916 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
917 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
918 nature.com's server, however, usee namespace
919 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
920 we are now using a glob-expr to match up the namespace. ZOOM C and
921 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
922 I can not find a single real example showing the "real" namespace in
923 the documentation from OASIS. The namespace for requests is different
924 from responses, but this is not added to YAZ yet, when we don't encode
927 --- 4.2.35 2012/06/26
929 zoom/record_render: add support for Base64 decoding fo MARC records
930 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
931 which will decode base64 + ISO2709 marc-8 encoded material from text node
934 --- 4.2.34 2012/06/07
936 Add missing definitions ZOOM_resultset_get_facet_field_by_index
937 and ZOOM_resultset_facets_names.
939 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
942 Change APDU dump printing to avoid long leading blanks. For levels 16
943 or larger the level is shown and the indentation is truncated but
944 recursed with modula 8. This makes it still reasonable easy to read
945 - even for nested BER dumps.
947 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
948 return 0 (incomplete package) in case where the BER package was
949 considered too nested (return value of -2).
951 dumpber: lines of level 15 are not indented further. Two spaces per
952 indentation; indentation 15 or more is indented to a fixed indentation
953 and augmented with a level=<no> indication.
955 zoomsh: increase max size of command+args
957 GFS: No limit in RPN buf size in CQL to RPN conversion.
959 --- 4.2.33 2012/05/09
961 New function for daemon utility, yaz_daemon_stop .
963 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
965 --- 4.2.32 2012/04/25
967 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
968 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
970 --- 4.2.31 2012/04/23
972 YAZ daemon utility relays SIGUSR1 to child process.
974 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
975 would result in en empty database list - which in turn would result in
976 encoding failure for search.
978 Fix reading beyond string in yaz_sort_spec.
980 --- 4.2.30 2012/04/11
982 Add two new SRU diagnostics:
983 236: Access to specified database denied
984 1015: Init/AC: Maximum number of simultaneous sessions for Userid
986 Document the very useful ZOOM-C option "apdulog".
988 CQL to RPN: term may be passed through verbatim. This is enabled with
989 truncation.cql . The assumption being that the term is already CQL.
991 --- 4.2.29 2012/03/20
993 record_conv: leader spec may be given for marc element.
994 The leader spec is given as attribute leaderspec for element marc.
995 For example to convert a MARC21 record from MARC-8 to UTF-8:
996 <marc inputformat="marc" outputformat="marc"
997 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
999 record_conv: allow user-XSLT params. For example:
1000 <xslt stylesheet="MARC21slim2DC.xsl">
1001 <param name="myparameter" value="myvalue"/>
1002 <param name="otherparameter" value="othervalue"/>
1005 record_conv: fix error handling for missing marc charsets.
1007 CQL: fix extra terms in wrong order.
1009 --- 4.2.28 2012/03/06
1011 record_conv: modify new API for conversion types. The conversion types
1012 may be passed in new functions yaz_record_conv_configure_t and
1013 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1015 Avoid mixed statement/variable declare; fixes compilation with Visual
1018 --- 4.2.27 2012/02/28
1020 Add non-standard SRU diagnostic: 235: "Database does not exist".
1021 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1022 Update SRU to Bib-1 diagnostic maps accordingly.
1024 CCL: add two new diagnostics for unsupported masking. The new
1025 diagnostics are: "Embedded truncation not supported" and
1026 "Single charcacter mask not supported".
1028 --- 4.2.26 2012/02/23
1030 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1032 --- 4.2.25 2012/01/11
1034 Build YAZ for Ubuntu Oneiric.
1036 CCL: allow parantheses for proximity operands. For example CCL query
1037 (a) % (b) is now allowed.
1039 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1040 marked dead, rather then being destroyed. If not, the session memory is
1041 being free'd before the search/scan handler is finished. Also destroy
1042 'request' memory in request_release rather than in various places,
1043 which resulted in leaks from time to time.
1045 --- 4.2.24 2011/12/21
1047 cql_sortby_to_sortkeys: honor sort prefix.
1049 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1050 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1051 The rpn2cql family of functions now always returns quoted CQL terms.
1053 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1055 --- 4.2.23 2011/12/15
1057 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1058 sequence is treated as one. For example, &&a=b&&&c& is identical to
1061 --- 4.2.22 2011/12/05
1063 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1064 APDUs for a connection to a WRBUF.
1066 --- 4.2.21 2011/11/23
1068 Fix cql_sortby_to_sortkeys. Completely broken before.
1070 Make CCL's @truncation work again.
1072 --- 4.2.20 2011/11/09
1074 New ZOOM connection setting: tproxy. It's like proxy, but does not
1075 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1076 to set resolved address + port for a connection outside ZOOM itself.
1078 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1080 --- 4.2.19 2011/11/07
1082 Fix uninitialized variable in Solr spell support (could cause SEGV
1083 for SRU response decoding).
1085 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1086 back-end's addinfo through into the ZOOM response addinfo.
1088 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1089 they are separated by a colon and a space rather than simply
1092 --- 4.2.18 2011/10/28
1094 Add support for Solr spell-checking/suggestions through ZOOM.
1095 If a Solr target has been configured correctly for spelling-checking
1096 and suggestions, these will now be returned on the ResultSet option
1097 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1099 --- 4.2.17 2011/09/28
1101 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1102 with a flag whether to substitute escape sequences or not.
1104 --- 4.2.16 2011/09/22
1106 Fix nmem_strsplit_escape to substitute escape char properly.
1108 New option for zoomsh -e , which makes it abort on first error and
1109 return process exit code to indicate success/failure.
1111 YAZ options utility supports special option -- which makes all it treat
1112 all following arguments as non-options.
1114 --- 4.2.15 2011/09/16
1116 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1117 searched if absolute filename is given.
1119 Fix conv_xslt() error-reporting when stylesheet is not found.
1120 (The value of fullpath is meaningless in this situation.)
1122 --- 4.2.14 2011/09/07
1124 Fix problem in CQL sort node creation: un-initialized memory.
1126 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1127 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1128 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1131 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1132 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1134 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1135 will make it possible to use both single-character mask (#) and wildcard (?)
1136 in CCL . Throw diagnostic for left truncation because that is not supported
1139 --- 4.2.13 2011/09/01
1141 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1142 cases using escapes (\-sequences) and masking.
1144 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1145 would result in a read one byte beyond string.
1147 rpn2ccl may use Z39.50 masking for terms (t=z).
1149 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1151 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1152 not --cppflags (which seeems like an error in icu-config).
1154 --- 4.2.12 2011/08/27 RPM package only
1156 cql2ccl: fix conversion of terms: operator characters were not
1159 --- 4.2.11 2011/08/25 RPM package only
1161 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1162 CCL parser will map both # and ? to their regular expression
1163 quivalents (. and .*).
1165 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1166 of reserved CQL characters.
1168 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1169 is, so that they are passed through.
1171 --- 4.2.10 2011/08/24
1173 ZOOM SRU mode: more aggressive re-connect.
1175 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1176 made available as a utility function, declared in <yaz/logrpn.h>
1178 rpn2cql_structure() supports proximity nodes (except that the Type-1
1179 proximity node's "exclusion" binary is ignored, as there is no way to
1180 express that in CQL). Fixes bug #4564.
1182 --- 4.2.9 2011/08/18
1184 Fix SEGV that could occur if set command of zoomsh was given without
1185 value (2nd argument).
1187 Fix SEGV that could occur if unsupported transport was given for
1188 COMSTACK - say https (when SSL was unavailable).
1190 Build yaz-url on Windows too.
1192 --- 4.2.8 2011/08/11
1194 New utility to get web content. Header is url.h. A command line tool
1195 yaz-url is part of the distribution and packages.
1197 Fixes for SSL COMSTACK (when gnutls is in use).
1199 New functions yaz_base64{encode,decode}. Header is base64.h.
1201 --- 4.2.7 2011/08/03
1203 ZOOM C includes HTTP response buffer as additional info if it fails
1204 to decode the SRU response.
1206 Make wrbuf_json_puts available.
1208 --- 4.2.6 2011/07/28
1210 zoom: throw diagnostic for invalid value for option "sru". Before a
1211 bad SRU request was sent.
1213 Adding new utility wrbuf_vp_puts.
1215 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1217 --- 4.2.5 2011/07/21
1219 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1220 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1221 redirect was used at the same time.
1223 MARC line mode decoding: be less picky about length given - first
1224 5 digits of header that is.
1226 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1228 Changes to decoding of SRU records: a record with recordPacking=xml is
1229 modified with a new root element <yaz_record> if the recordData contains
1230 multiple children elements. This is to make the record XML parseable
1233 RPN to Solr conversion: encode special characters.
1235 Generic Frontend Server: fix uinitialized member, stepSize.
1237 --- 4.2.4 2011/06/21
1239 Fix a bug in SRU decoding of records.. The database records stored
1240 had un-initialized memory, but it would only be seen with yaz_record_render
1241 and type_spec="ext" .
1243 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1245 --- 4.2.3 2011/06/17
1247 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1249 --- 4.2.2 2011/06/10
1251 Add new utilities to convert from CQL to CCL . These utilities have
1252 prefix cql_to_ccl defined in cql.h.
1254 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1255 lead to memory heap corruptions when ICU utilities were in use.
1257 --- 4.2.1 2011/06/07
1259 Make compilation work without Libxml2.
1261 yaz-client: remove redundant blanks in display of searchResult-1 term
1264 --- 4.2.0 2011/05/18
1266 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1267 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1269 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1270 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1271 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1272 Note that the CQL sortby spec is only converted when the GFS is already
1273 converting from CQL to RPN (cql2rpn element).
1275 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1276 specify whether to collapse delimitors or not. The existing nmem_strsplit
1277 do collapse (collapse parameter = 1).
1279 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1281 Rename internal func yaz_use_attribute_create. While non-static, this
1282 function is not declared in a public header.
1284 --- 4.1.7 2011/03/15
1286 Add -lCrun when linking with ICU on Solaris.
1288 More quicks character set conversions for OPAC records.
1290 --- 4.1.6 2011/03/10
1292 fix problem with record_render: records were converted (character set
1293 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1295 --- 4.1.5 2011/03/08
1297 SRU: add methods for handling DADS SRU-proxy facets.
1299 Separate OPAC record character set for ZOOM_record. yaz_record_render
1300 allows a character set given as charset=from/opacfrom,to where 'from' is
1301 the character set of a bibliographic record, 'opacfrom' is character set
1302 of OPAC record and 'to' is the target character set.
1304 --- 4.1.4 2011/02/21
1306 yaz-client: show may XML format records. Command show followed by 'format'
1307 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1310 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1313 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1315 --- 4.1.3 2011/01/27
1316 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1318 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1319 this package can be distinguished from other vendors.
1321 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1322 as determined by configure
1324 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1326 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1327 returns no error and no record, the present request is considered
1328 partial (only a subset of the records could be returned by backend), and
1329 so it is appropriate to set Present Status to partial-4.
1331 --- 4.1.2 2010/11/02
1333 Move yaz-config man pages to section 1.
1335 More documentation about Solr.
1337 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1338 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1339 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1340 peers on some Linux systems. However, in general that does not work
1341 so YAZ can not rely on that to work. Debian changed behavior in this
1342 respect from Debian lenny to Debian squeeze (still testing as of Oct
1344 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1346 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1348 --- 4.1.1 2010/10/05
1350 Fix yaz-config output: echo_source not set correctly by configure.
1352 --- 4.1.0 2010/10/05
1354 Solr Web Service support for yaz-client and ZOOM.
1356 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1358 --- 4.0.12 2010/08/17
1360 Z39.50 facet support. Facet specifications are passed for search in
1361 other-information with ASN.1 as defined in facet.asn and OID
1362 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1363 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1364 3 is limit (number of entries to get in response). yaz-ztest returns
1365 dummy facets if a client asks for them.
1367 --- 4.0.11 2010/07/09
1369 CCL fixes: bug 2895 and bug 3539.
1371 GR1-display: add comma in display - was removed by mistake in
1374 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1376 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1378 --- 4.0.10 2010/06/18
1380 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1381 result set from a connection. The result set will be on its own
1382 thereafter; no operations on it will perform retrievals from a target.
1383 Only cached copies are returned.
1385 ZOOM C:fix case for HTTP servers responding with Connection:close.
1386 Ensure that if there is a current task it is resumed (like fetching
1387 more records in a result set) . Bug #3484.
1389 PQF parser: use odr_atoi for Odr_int (not atoi)
1391 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1392 values that contain any non-digits are treated as string attributes
1393 (previously decoding only checked for leading character ([0-9]). PQF
1394 encoding: attribute string values are not surrounded by double-quotes.
1396 --- 4.0.9 2010/05/21
1398 New utility for managing threads - thread_create.h.
1400 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1401 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1402 but YAZ' implementation do.
1404 Fixes for yaz_cond-functions on Windows 7.
1406 DLL export more symbols.
1408 zoomsh: show record do NOT render opac.
1410 Remove *.la files from Debian and RPM packages.
1412 --- 4.0.8 2010/05/11
1414 Debian package libyaz-dev depends on libgnutls-dev again (was
1415 removed in YAZ 4.0.6, but due to Libtool it is still needed
1416 even though yaz-config do not list libgnutls libs).
1418 ZOOM: Use only one WRBUF for returning string results for
1419 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1421 ZOOM: ZOOM_connection do not use a shared pointer to
1422 ZOOM_resultset after ZOOM_resultset is destructed by
1423 user. Reverts to YAZ 4.0.4 behavior.
1425 --- 4.0.7 2010/05/04
1427 record-conv: fix problem with at least one XSL conversion -
1428 due to probably incorrect usage of XML XSL documents.
1430 --- 4.0.6 2010/04/29
1432 Fix yaz-config for static mode and the use of SSL (gnutls).
1434 --- 4.0.5 2010/04/29
1436 Forward decl timeval struct in mutex.h and gettimeofday.h.
1438 yaz-config: fix 'static' mode linking.
1440 --- 4.0.4 2010/04/28
1442 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1443 are wrappers for pthreads or Windows. For Windows these are put in
1444 a separate DLL: yaz_cond4.
1446 libyaz.la (whole source) is compiled with thread. If thread support
1447 is enabled enabled, all source of YAZ is compiled with treading support.
1448 This allows core utilities such as yaz_log to use thread facilities.
1449 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1450 thread utilities. This commit moves mutex utilities (mutex.c) from
1451 libyaz_server.la to libyaz.la.
1453 yaz-json-parse displays leading text until error.
1455 --- 4.0.3 2010/04/09
1457 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1458 patch from Giannis Kosmas.
1460 SRU: no longer URL encode SRU database. The URL for an SRU server is
1461 a URL and such is alreeady encoded - at least when given with leading
1462 http:// or https://. This reverts behavior to YAZ 3.0.50.
1464 Support for new MARC XML notation TurboMARC which like MARCXML is a
1465 complete representation of MARC/ISO2709.. This one, however, is more
1466 compact and allows for faster processing with XSLT. TurboMARC can be
1467 used in the marcdisp.h API, from the yaz-marcdump utility and from
1470 yaz-ztest can be configured - via the database - to perform certain
1471 delays when it performs operations search, present and single record
1472 fetch. This allows testers to make yaz-ztest act as a real or even slow
1473 Z39.50 server. Refer to the yaz-ztest man pages for details.
1475 --- 4.0.2 2010/03/09
1477 wrbuf_destroy allows NULL WRBUF passed to it.
1479 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1481 Add ZOOM_connection_close.
1483 No fixed size buffers for ZOOM shell - bug #3257.
1485 tstodr: make it work on s390 platform.
1487 New icu iterator-functions. The new icu_iter-functions makes it possible
1488 to use ICU chains from many threads.
1490 yaz-client: better syntax check for show command.
1492 --- 4.0.1 2010/01/26
1494 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1497 New simple local-file XML include facility which allows file glob-patterns.
1498 Refer to yaz/xml_include.h.
1500 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1503 ZOOM_record_get supports new parameter "format" which makes it format XML
1506 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1507 JSONText in ECMA-262) is JSONValue, not JSONObject.
1509 --- 4.0.0 2010/01/20
1511 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1512 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1514 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1515 POSIX/Unix builds .so with major version 4.
1517 Remove old LOG_-defines from log.h. They have been obsolete and
1518 undefined by default for the last 5 years.
1520 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1522 GFS: Remove socket (int *fd) from search_rr handler. The socket
1523 descriptor ptr is a facility that allowed a search handler to supply
1524 a socket which would serve as a callback - when search was complete.
1525 This facility has now been in use for years.
1527 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1528 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1529 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1530 returns 'const char *' rather than 'char *. The returned string is
1531 read-only and should not be modified by applications. COMSTACK cs_close is
1532 now a void function - it no longer returns int. No applications check for
1533 the value and the implementations has always returned 0.
1535 ZOOM: use size_t for scan hit counts and str size. Functions
1536 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1537 occ (hit count) and len (string length) are now of type size_t pointer
1538 rather than int pointer. This is to be able to represent large hit counts
1539 and to also just to use the proper type for string length (strlen result).
1541 New JSON parser. Refer to include/yaz/json.h .
1543 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1544 Used to be int in some cases. Many wrbuf_-functions used to return an int
1545 indicating some length.. These return values were never used. And so they
1548 ODR: odr_malloc, odr_total now takes size_t for size.
1550 clone_z_type: fix leak; occurred for encoding failures.
1552 --- 3.0.52 2009/12/03
1554 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1555 bug was introduced in 3.0.51.
1557 --- 3.0.51 2009/12/02
1559 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1561 tcpip comstack: fix leak for getaddrinfo.
1563 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1564 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1565 Decoding of SRU "path" database is performed by private function
1566 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1567 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1569 yaz-client: honor base command for SRU. Change when database setting
1570 is applied for SRU and ensure it is kept when a connection is reset.
1571 Change also the way errors are displayed or SRU (decoding of packages).
1573 --- 3.0.50 2009/11/02
1575 Add support for extra request / response data for SRU codecs and GFS.
1576 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1577 for extra data response buffer and length. For the GFS, both request
1578 and response data (XML) is carried in extra_args and extra_response_data
1579 for the search handler. Patch by Ko van der Sloot.
1581 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1582 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1583 10010). This fixes bug #2113.
1585 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1586 cmdfile included a 'quit' command that would result in a memory violation.
1588 --- 3.0.49 2009/10/01
1590 Make a number of functions defined in xmlquery.c static. These have
1591 never been declared in a public header file (yaz/xmlquery.h) and was
1592 made public by mistake.
1594 Improve speed of character conversions (iconv utilities). This makes
1595 conversions from MARC-8 faster.
1597 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1598 unless type desired is "raw". This will prevent type "xml" from
1599 returning ISO2709 .. Which obviously can not be XML parsed.
1601 Fix memory leak in ZOOM that would occur if option apdulog was used
1602 on a re-used connection.
1604 Frontend server logs HTTP requests.
1606 Frontend server now sends Z39.50 close when it times out (sesssion has
1607 been idle for too long). Versions 2.0.30 and earlier also sent close.
1608 But due to a mistake this was disabled in all versions after that, i.e.
1609 the server would just close the socket immediately.
1611 yaz-client emits a better message when receiving an unrecognised
1612 userInformationField.
1614 Skip zero-length subfields when decoding ISO2709. This rare case happens
1615 if a record has two FS characters in a sequence. Without this patch
1616 there would be a reference beyond char array in using_code_len fragments
1619 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1621 --- 3.0.48 2009/08/28
1623 The show command offered by the zoomsh command now takes a 3d optional
1624 parameter type which is what is passed to ZOOM_record. If the type
1625 argument is omitted, "render" is used.
1627 RPN to CQL conv may use USE string attributes (bug #2978).
1629 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1631 --- 3.0.47 2009/07/08
1633 Function yaz_xml2query allows a diagnostic element in the PQF XML
1634 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1635 code and additional info respectively.
1637 The BER BOOLEAN is now the integral type Odr_bool which still happens
1638 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1639 typedef'd to Odr_int. This is still an integral 'int', but it may be
1640 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1641 ASN-1 compiler as well as programs has been updated to use the new types.
1643 --- 3.0.46 2009/06/08
1645 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1646 only the bibliographic record was rendered. For type=opac, an OPAC
1647 record is only returned if it is present.
1649 iconv: small fix for encoding of advancegreek.
1651 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1653 yaz-client: option auto_reconnect=on really reconnects.
1655 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1657 server: avoid null ptr ref for for yaz_poll errors.
1659 build: fix RPM build for RHEL 5.3.
1661 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1663 --- 3.0.45 2009/03/31
1665 Fixed bug #2709: TCP connect returns Invalid argument.
1667 Fixed compilation for mingw.
1669 Honor charset for raw records (ZOOM_record_get).
1671 Fixed use of errno for threaded mode that was seen on Solaris 10.
1673 Fixed argument passing with blanks in value for Windows Service.
1675 Disable YAZ' own log rotate by default (no 1 GB limit).
1676 The variable l_max_size which specifies the log file limit is set to 0
1677 (DISABLED): This is due to the fact that YAZ is most often deployed using
1678 logrotate. Also YAZ can not perform log rotate because of unsufficient
1679 permissions (setuid).
1681 --- 3.0.44 2009/02/17
1683 List supported encodings in man page for yaz-iconv.
1685 Fixed missing SSL libs for --libs output
1687 Re-established OID record syntax application-xml. Nobody should use it
1688 but we don't want to change soname because of this symbol being absent.
1690 --- 3.0.42 2009/02/02
1692 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1694 Added member named_result_sets for init handler struct for the GFS. This
1695 allows a server to disable named result sets.
1697 Removed OID record syntax application-xml.
1699 Added support for rule-based transliterator for ICU wrapper of YAZ.
1701 Fixed bug #1902: yaz-icu XML output.
1703 Make YAZ checks Emacs friendly.
1705 BITSTRING value shows value. Bug #2346.
1707 ISO2709 decoding: skip control characters from indicator data.
1709 Omit sort key by default in yaz-icu's output.
1711 Allow combined single char options (again) for YAZ' options function.
1713 Utility yaz-marcdump got option to display YAZ version (-V).
1715 Allow YAZ to use ICU 3.4.
1717 Added new ICU test case which illustrates removal of diacritics.
1719 --- 3.0.41 2008/12/29
1721 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1723 --- 3.0.40 2008/12/29
1725 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1728 Fixed bug #2352: yaz-marcdump crashes for certain record.
1730 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1732 Added support for Danmarc2 to UTF-8 conversion.
1734 Added support for ISO5426 to UTF-8 conversion.
1736 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1737 implementation version.
1739 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1741 --- 3.0.38 2008/11/10
1743 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1744 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1746 ZOOM C now interprets databaseName option for ZOOM connection as path
1749 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1751 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1753 Dummy Libxml2 types no longer defined in headers of YAZ'.
1755 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1758 --- 3.0.36 2008/09/26
1760 Various ODR chapter fixes.
1762 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1764 Added missing source for Windows compilation, mutex.c.
1766 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1768 For SRU connections in ZOOM all records up to "count" are now fetched.
1770 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1771 in Windows due to bad error handling for Libxml2.
1773 Added facility for sending arbitrary records (ASN.1 any) using
1774 ZOOM C's Extended service update. Patch by Sam Reynolds.
1776 New options for ZOOM C's connection, logapdu which makes ZOOM log
1779 --- 3.0.34 2008/06/18
1781 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1783 --- 3.0.32 2008/06/12
1785 Fixed memory violation that could occur when decoding UTF-8. This bug
1786 was only present in 3.0.30 of YAZ.
1788 --- 3.0.30 2008/06/06
1790 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1791 GNU TLS is used by default (if found).
1793 yaz-ztest returns OPAC records if a client asks for OPAC.
1795 Improved speed of MARC-8 encoding.
1797 Added support for lossy and loss-less MARC-8 encoding.
1799 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1801 Added new Windows Service wrapper (sc).
1803 yaz-client's itemorder command may now send a file.
1805 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1807 Added new function yaz_log_xml_errors.
1809 Allow (but warn) unknown XML attributes in MARCXML parsing.
1811 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1813 The UTF-8 to MARC-8 conversion now uses a different set of characters
1814 for Greek symbols. Bug #2120.
1816 --- 3.0.26 2008/02/21
1818 Added yaz_daemon (daemon.h).
1820 Fixed bug #2068: pkg-config trouble
1822 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1824 --- 3.0.24 2008/01/28
1826 Document --with-xml2 option.
1828 Added OPAC XML XSD (etc/opacxml.xsd).
1830 Allow glob mask for name attribute in retrieval element for the
1831 generic frontend server's retrieval facility.
1833 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1834 except POLLIN/POLLOUT.
1836 Fixed error handling in cs_listen. Bug #2037.
1838 --- 3.0.22 2008/01/20
1840 Fixed version in yaz/yaz-version.h.
1842 Fixed bug #2027: Crash when closing connection.
1844 Changed configure so that ICU support is only enabled if only ICU
1845 and Libxml2 is available (because the ICU chain is XML based).
1847 --- 3.0.20 2008/01/15
1849 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1850 is built. Only this DLL depends on the ICU runtime.
1852 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1853 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1855 Changed license of CCL module to 'Revised BSD'. After consultation with
1856 remaining members of the original EUROPAGATE consortium, we are re-issuing
1857 the CCL module without a separate license. The software was developed by
1858 Index Data as part of a research project. The special license was included
1859 to help feed usage information back to the project consortium to support
1860 project evaluation. At this time, the project consortium has long-since
1861 disbanded, and the majority of the original principals have retired. At the
1862 same time, we have significantly modified the software during the following
1863 years, to the point where very practically no original code remains. To
1864 simplify re-use of the software, we have contacted those members of the
1865 consortium who could be reached, and agreed to re-issue the module as a
1866 proper part of the YAZ package.
1868 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1870 CQL closer to being version 1.2 compliant. CQL also allows free-form
1871 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1874 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1875 bug could make Extended services handling crash in the ZOOM layer. This
1876 bug was only present in YAZ 3.0.18.
1878 --- 3.0.18 2007/12/19
1880 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1883 yaz-marcdump reads and writes collection wrapped records.
1885 Handle OPAC for record conversion module.
1887 Fixes for ICU wrapper.
1889 Allow ICU libs to be controlled with --with-icu .
1891 --- 3.0.16 2007/11/12
1893 Added yaz_poll which is a wrapper for select/poll. When poll is available
1894 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1895 sockets to be in use.
1897 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1898 functionality through an XML based configuration (ICU chain). This system
1899 is useful for search facilities such as Pazpar2 and Zebra that needs to
1900 perform tokenization of indexed material. The ICU code in a separate
1901 library libyaz3_icu.a.
1903 Added HTTP tunnel facility for COMSTACK, bug #1752.
1904 This is a facility that allows a Web proxy, such as squid, to tunnel
1905 Z39.50 traffic. This facility is "transparent" to must applications
1906 using YAZ. It's enabled by using pseudo transport connect: followed by
1907 the proxy address, followed by command, then follwed by he regular
1908 "virtual" addresss. For example,
1909 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1911 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1913 --- 3.0.14 2007/09/21
1915 Fixed bad memory reference in ZOOM_record - cuased by member not being
1916 initialized. This was a problem only in YAZ 3.0.12.
1918 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1919 fields were not removed.
1921 Changed the way C code is generated from codetables.xml. Made a MARC-8
1922 conversion trie for each characterSet section rather than codeTable.
1923 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1924 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1926 --- 3.0.12 2007/09/12
1928 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1929 from ZOOM_record_error).
1931 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1933 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1935 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1937 Better SRW-to-Bib-1 diagnostic mapping.
1939 ZOOM C and yaz-client announces SRU version 1.2 by default.
1941 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1944 Fixed in yaz_sru_decode to allow other version than 1.1.
1946 --- 3.0.10 2007/08/22
1948 Added support for SRU scan for ZOOM.
1950 Added support for the use of the older versions or Extended Service
1951 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1952 set to the version , 1=first, 2=second, 3=third. The third version is
1953 what ZOOM C has used so far. And that, obviously, is the default.
1955 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1956 therefore in Zebra and in SimpleServer-based applications). The new
1957 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1958 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1959 which is passed into the back-end search callback function.
1961 Added support for HTTP Basic authentication in clients: the SRU/W
1962 codec encodes the username/password elements of the PDU structure
1963 appropriately, and these may be set using the "user" and "password"
1964 options in ZOOM-C applications (the same options that are used for
1965 Z39.50 authentication).
1967 --- 3.0.8 2007/06/25
1969 Fixed bug #1208: SSL appears to be broken in ZOOM.
1971 Fixed bug #1206: Libxml2 include path weirdness.
1973 Added oid_name_to_dotstring.
1975 Allow elementSetName to be specified for ZOOM C record update.
1977 Allow waitAction to be specified for ZOOM C based for Extended Services.
1979 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1980 syntax OID. Bug introduced in YAZ 3 series.
1982 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1984 --- 3.0.6 2007/06/06
1986 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1987 directory. yaz-client now reads commands from file given by option -f
1988 if specified; then tries to read .yazclientrc in current directory.
1989 Failing that, it reads .yazclientrc from user's home directory.
1991 Added support for correlationInfo Note and ID for Record Update via
1994 Added yaz-client command querycharset which specifies character set for
1995 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1996 (termListAndStartPoint).
1998 Charset ISO5428:1984 is an alias for ISO5428-1984.
2000 Implemented a way to perform scan in a result set using Z39.50. This
2001 is achieved by attaching the result set name in the characterInfo
2002 (type InternationalString) of OtherInformation in the Scan Request PDU.
2003 The result set is identified in the otherinformation by the new OID:
2004 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2005 This allows for scan in result set and faceted search . Zebra did some
2006 of this in the APT term using attribute type 8 and value being result
2007 set. Using the OtherInformation approach for this is cleaner and easier
2008 to work with in proxies and the like. This facility can be used in
2009 yaz-client using new command setscan which takes a result set as first
2010 argument, start position (APT) as second.
2012 Changed decoding of SRU XML packed records to deal with servers that
2013 have recordData with XML data with multiple root nodes. Also make
2014 comparison for recordPacking case insensitive. Again, one server
2015 returns "XML" where others return "xml".
2017 For SRU responses allow Content-Type application/xml as well as text/xml.
2019 --- 3.0.4 2007/05/21
2021 Fixed bug in character set conversion of BER strings. Bug introduced
2024 --- 3.0.2 2007/05/08
2026 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2028 For OID class, use oid_class consistently.
2030 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2033 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2034 character set for bibliographic information interchange". By Giannis Kosmas.
2036 Added documentation on new OID API.
2038 --- 3.0.0 2007/05/02
2040 Changes to generic frontend server interface: added new member
2041 'query_charset' for bend_initrequest structure. A backend init handler
2042 should set this member to its native character set for query terms.
2043 When defined, the frontend server logic will announce this character set
2044 to a client if the negotiationModel bit is set by the client. All server
2045 implementors are encouraged to specify this. If a backend server does not
2046 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2048 Added CCL utility to remove terms (stop words) from resulting RPN
2049 tree. This is handled by functions with prefix ccl_stop_words_ .
2051 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2052 terms in RPN queries.
2054 Clean-up the CCL API. Moved some internal structures from ccl.h to
2055 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2056 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2057 This is replaced by ccl_parser_find_str which takes a string instead.
2059 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2060 libyaz.la is the core of YAZ except the generic frontend server and
2061 does not depend on POSIX threads anymore. libyaz_server.la is the
2062 generic frontend server facilities and uses POSIX thread functionality
2063 if available. The libyaz.la no longer depends on POSIX threads because
2064 the number of global structures is limited. NMEM no longer re-uses blocks
2065 between threads ; it simply free's memory immediately but allocates in
2066 "large" chunks as usual. We don't expect any performance penalties
2067 because of this. The yaz_log system is still using a global log_level so
2068 caution must be taken when modifying it with yaz_log_init_.. +
2069 yaz_log_mask_str. This, however, should not cause any trouble because
2070 these functions are called during initialization of application code
2071 anyway. `yaz-config --libs server` returns libs for server applications;
2072 `yaz-config --libs` returns libs for non-server applications.
2074 New OID database - with public definitions in oid_db.h. Removed old OID
2075 database including the head oid.h and definitions such as enum oid_value
2076 and struct oident. The new OID database uses the same string names as
2077 before but the 'protocol' is gone. There are now only two representations
2078 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2079 converts from string to OID; functions with prefix yaz_oid_to_string
2080 converts the other way.
2082 Change to emit_term() in CQL-to-PQF query translation: when a term has
2083 the /regexp relation modifier, do not process it for leading and
2084 trailing "^" and "*", which have quite different meanings in regular
2087 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2088 write handlers no longer carries a 'last' parameter. This will make
2089 yaz_iconv flush "less" characters. A flush is performed by call to
2090 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2092 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2093 removed, because function yaz_query_to_wrbuf does the same.
2095 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2096 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2098 Deprecated MARC utility functions removed.
2100 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2103 Branch split: YAZ_2_1_55_branch
2105 --- 2.1.54 2007/03/16
2107 Fix to ZOOM-C so that transparent reconnection is properly handled on
2108 connections that are in asynchronous mode.
2110 Fixed compilation on OpenBSD 4.0.
2112 Large strings in GRS-1 records are now properly displayed in yaz-client.
2114 Added character conversion support for "advancegreek"; based on patch from
2117 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2118 sequence is met. Before the error was not set so it would be unknown.
2120 Adjust yaz-marcdump MARC reader so that it skips until record separator
2123 --- 2.1.52 2007/03/07
2125 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2126 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2127 fd_set structure used as a bitmask for the FDs to be selected on.
2129 Using ACX_PTHREAD macro to check for POSIX threads.
2131 Fixed have-vsnprintf check.
2133 --- 2.1.50 2007/02/23
2135 Fixes for configure on BSD. Bug #900.
2137 Added snprintf/vsnprintf wrappers for systems that don't have
2138 limits (heavens forbid).
2140 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2141 created before all previous tasks were completed and removed from the
2142 task queue, the new task could be removed by a mistake.
2144 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2146 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2148 Fixed bug #832: Problem with MARC/charset in yaz-client.
2150 Fixed bug #668: save command line history for yaz-client.
2152 Fixed bug #830: pkg-config support.
2154 --- 2.1.48 2007/01/23
2156 Extended ZOOM result set options with two options that may be read by
2157 a client: resultSetStatus and presentStatus with values as specified for
2159 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2161 Fixed bug #827: Using SSL fails on Debian etch.
2163 Fixed bug #826: Weird looking chars for set of MARC records.
2165 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2166 that is treated as an ItemOrder with itemRequest being an XML document
2167 external. The value of "doc" is the content.
2169 Extended the GFS search facility. New member of bend_search_rr
2170 'estimated_hit_count' signals that hits is known to be an estmate
2171 (higher or lower than real hit count). New member 'partial_resultset'
2172 signals that the search was partial (hit count is lower or equal than
2173 real hit count). For Z39.50, the information is stored in resultSetStatus
2174 member of SearchResponse APDU. For SRU, the information is signalled
2175 via SRU diagnostic 59: "Result set created with valid partial results
2178 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2180 --- 2.1.46 2007/01/13
2182 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2184 Added ZOOM_connection_peek_event.
2186 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2187 the following new functions:
2188 ZOOM_event_nonblock, ZOOM_connection_process,
2189 ZOOM_connection_get_{socket,mask,timeout},
2190 ZOOM_connection_fire_event_{timeout,socket}.
2191 The existing blocking event handler, ZOOM_event, is a wrapper for the
2192 + blocking ZOOM_event_sys_{poll,select}.
2194 Implemented function ccl_xml_config which parses XML version of CCL
2195 configuration (bug #798).
2197 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2199 Added timings utility (yaz/timing.h)
2201 --- 2.1.44 2007/01/03
2203 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2206 Fixed bug #779: Rotation of apdu.log fails.
2208 Fixed for character set conversions:
2209 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2210 Honor G1 set in MARC-8 decoding.
2212 --- 2.1.42 2006/12/17
2214 Fixed bug #775: char conversion does not handle Alternative UTF-8
2217 Implemented function yaz_marc_read_line which parses MARC line format
2218 records. There is a wealth of formats out there. So far, this function
2219 reads line records produced by yaz_marc_write_line.
2221 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2222 more generic and easier to remember(!) options: -i format and -o format
2223 which specifies input format and output format respectively - where
2224 format is one of "marc", "marcxml", "line", "marcxchange".
2226 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2227 does not print anything except warnings for records.
2229 For yaz-marcdump, added support for MARC split into files (-s) with a given
2232 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2233 spec, at http://www.loc.gov/standards/sru/record-update/
2234 This has changed the binary layout of the following structs:
2235 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2236 bend_update_rr . Patch by Ko van der Sloot.
2238 Added GFS utility function bend_assoc_is_alive which returns 1 if
2239 association is still alive (client is connected); 0 otherwise (client
2240 closed connection). This allows busy servers to stop working for
2243 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2244 been a separate piece of software. This version of ziffy has been modified
2245 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2247 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2249 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2250 Client code may now interrogate options such as "init_opt_sort" to
2251 find out whether the server claims to support various options.
2253 --- 2.1.40 2006/11/27
2255 Added utilities yaz_{set,get}_esn to set/get element set name from
2258 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2259 of YAZ and has been so since YAZ 2.1.10.
2261 Implemented ZOOM_record_error which returns error information for
2262 record (surrogate diagnostic).
2264 --- 2.1.38 2006/10/31
2266 Updates for SRU Update by Ko van der Sloot:
2267 1. Changed name from "operation" to "action"
2268 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2269 versions in the code, marked as 'backward compatible'.
2270 3. Added diagnostics for SRU Update.
2272 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2274 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2276 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2278 For GFS, fixed problem with SRU diagnostic 'First record position out of
2279 range' being issued for 0 hits.
2281 zoomtst10 part of Windows Build.
2283 --- 2.1.36 2006/10/13
2285 Implemented yaz_filepath_comp which splits a path into file path
2286 components (required by Zebra 2.0.3+).
2288 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2289 BSD inspired license until now so this should not have any real impact on
2290 anybody. See http://www.opensource.org/licenses/bsd-license.php
2292 Fixed bug #687: Missing log lines.
2294 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2297 Fixed bug #689: SRU diagnostics to be added.
2299 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2300 whether a connection is idle (no more work do do).
2302 --- 2.1.34 2006/10/04
2304 Change type of optval from long to int for invocation of setsockopt with
2305 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2307 Added support for specifying the max log file size for the Generic
2308 Frontend Server. The size is given with option -r.
2310 --- 2.1.32 2006/09/21
2312 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2314 --- 2.1.30 2006/09/17
2316 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2319 Fixed bug in Generic Frontend Server that could cause a server to stop
2320 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2322 For the generic frontend server, the maximum record size is used as maximum
2323 size of incoming packages (SRU + Z39.50). The value until was previously
2324 only used in Z39.50 Init negotiation and, later, in a session controlled
2325 sizes of records returned. This is controlled using -k option. It can be
2326 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2328 --- 2.1.28 2006/09/04
2330 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2333 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2335 New option for yaz-marcdump -lpos=value which allows setting a portion
2336 of MARC header to a certain value.
2338 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2340 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2341 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2343 --- 2.1.26 2006/08/15
2345 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2348 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2350 --- 2.1.24 2006/08/08
2352 Fixed MARC ISO2709 encoding routines to deal with character set
2355 Minor changes to GFS logging. Database included in search request log
2358 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2359 cached/multiple records.
2361 Shared libraries are built by default on Unix+configure.
2363 Changed cql2pqf transformation to use a different evaluation order. The
2364 new order is: always, relation, structure, position, truncation, index
2365 and relationModifier. Old order was: always, relation, relationModifier,
2366 structure, index, position, truncation. Note that the the latter ones
2367 override former ones for identical attributes.. The new scheme means that
2368 it is possible to override any existing attribute with a relationModifier.
2369 And also that it is possible to override everything for the index rule
2370 (except the ones listed in relationModifier). No order is perfect but this
2371 one, we believe, covers more real cases.. The "always" should have been
2372 called "default", since the attributes there can be overridden with all
2375 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2376 compilation phase, but also for yaz-config --cflags output. This allows
2377 us to have public headers with Libxml2 stuff in them . It should also,
2378 eventually, make Libxml2 checks redundant in packages using YAZ, such
2381 --- 2.1.22 2006/06/15
2383 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2384 stored in uri, message and details.. Previously diagnostics were stored
2385 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2386 compatibility.. but he's probably the only one affected, so.
2388 Added support for CCL, compiled on the client side, in ZOOM-C. This
2389 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2390 input; the resulting query objects can be used for for searching with
2391 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2393 YAZ' configure searches for OpenSSL by default.
2395 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2396 SL_CTX_use_certificate_file. See
2397 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2398 for more info. Thanks to Ko van der Sloot.
2400 --- 2.1.20 2006/06/02
2402 Bug #600: SRU GET, POST support for yaz-client. Introduced
2403 command 'sru' which selects method SOAP/GET/POST.
2405 Allow missingValueAction to be specified for the sortspec string -
2406 function yaz_sort_spec. By default, the missing value action is null.
2407 Use ! to specify "abort". Use = followed by stringvalue to specify default
2410 Ensured that Present-handler (if defined) is called in GFS before any call to
2411 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2412 searchRetrieve requests.
2414 Documentation for YAZ is now based on the Docbook XML/XSLT using
2415 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2416 is no longer depending on jade/openjade or docbook-to-man scripts.
2417 PDF is no longer part of the distribution - but can optionally be
2418 made using DSSSL/jadetex or FOP.
2420 Added retrieval handling support in Generic Frontend Server to support
2421 conversion between MARC/XML as well as XSLTtransforms. See
2422 etc/yazgfs.xml for an example.
2424 Added Authentication support to Generic Frontend Server in SRU
2425 mode. Authentication using HTTP Basic is supported, as is the use
2426 of 'x-username' and 'x-password' parameters in the request itself.
2428 Added support for a new character set MARC8s identical to MARC8 except
2429 that it converts combined characters to single Unicode characters in the
2430 Latin-1 range (when possible).
2432 --- 2.1.18 2006/04/24
2434 ASN.1 compiler 0.4: generates brief Doxygen file header for
2435 generated .h/.c files.
2437 Utility yaz_iconv now supports conversion to MARC-8.
2439 New facilities for the MARC module. The reading - and writing of
2440 content are separate methods for the yaz_marc_t handle. The following
2441 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2442 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2443 format). Write functions have prefix yaz_marc_write_.. The existing
2444 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2445 available. Removed support for OAI-MARC and simplexml (not the
2446 simplexml from PHP5).
2448 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2449 to be returned for this connection.
2451 --- 2.1.16 2006/03/31
2453 Allow multiple languages and charsets to be specified with
2454 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2455 negcharset iso-8859-1,utf-8
2457 Translation of proximity nodes from CQL into PQF now works.
2459 Moved to automake 1.8, 1.9.
2461 Added function yaz_log_set_handler which allows a log handler to be
2462 installed. This handler will be called for all log messages. Output
2463 to file is also produced; but that can be disabled by passing NULL
2464 fname to yaz_log_init_file.
2466 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2468 For SRW (including GFS), accept application/soap+xml as content-type
2471 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2472 produces NO stylesheet reference even if a default stylesheet is specified
2475 --- 2.1.14 2006/03/14
2477 Updated Windows package to include yazd.dll + yazd.lib for the
2478 Development component.
2480 If the environment variable YAZ_LOG is set, then it is used as a
2481 string indicating the default level of logging to use if not
2482 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2483 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2484 used as before. So, for example, to omit warnings from YAZ logging,
2485 export YAZ_LOG=-warn
2487 cql_transform() now map structure and other attributes before indexes,
2488 so that index-specific structures and other attributes can override
2489 defaults. So now a combination of mapping specifications such as:
2491 index.dc.date = 1=date-modified 4=5
2492 does the right thing.
2494 cql_transform() now also respects the "always" mapping specification,
2495 which establishes an initial set of attributes to be used for all
2496 terms except where overridden by more specific attributes associated
2497 with the index, relation or modifier.
2499 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2500 which mode to use; one of "post", "get" or "soap" (SRW, default).
2502 Fixes for yaz_iconv routines: changed trie-based character set conversions
2503 to use only non-negative values for bit fields due to Sun's C compiler not
2504 supporting negative values.
2506 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2507 sequences where not read correctly. Fix by Rustam Usmanov.
2509 Updated win/makefile to use options, settings which makes things
2510 compile with VS C 2005.
2512 --- 2.1.12 2006/02/01
2514 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2516 In ZOOM socket code, use select instead of poll on MacOSX.
2518 ZOOM-C now support client-side compilation of CQL into RPN that is
2519 sent to the server, enabling CQL to be used against all Z39.50
2520 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2521 ZOOM_query object, and submit it using ZOOM_connection_search().
2522 The CQL-to-RPN translation uses a configuration file, the name of
2523 which must be specified in the Connection's "cqlfile" option.
2525 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2526 function, which takes as its start-term parameter a ZOOM_query object
2527 (which may have had either CQL or RPN set into it).
2530 --- 2.1.10 2005/11/29
2532 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2533 GFS to support this as well. Backend handler, bend_srw_update, does the
2534 update work. Code contributed by Ko van der Sloot.
2536 Allow retrieval of Search Result-1 information in ZOOM by the use of
2537 options that are attached to a result set. ZOOM documentation updated
2540 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2541 UTF-8 conversion. Patch by Raj Patel.
2543 Added option -m to GFS to control formatting of timestamps in log file.
2545 Added 'exit' as synonym for 'quit' in yaz-client
2547 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2548 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2549 for the new members. Patch by Ko van der Sloot.
2551 Added support for SRU POST. It is supported for content-type
2552 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2554 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2555 Instead make the library libyaz.la multi-threaded. Threading as a whole
2556 can still be disabled by configure option --disable-threads. Previosly,
2557 with older GLIBCs there were problems with MT libs under Apache. This
2558 has now been fixed a long time ago.
2560 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2563 CQL module modified to be case insensitive for relations/indexes/operations.
2565 Fixed bug in CQL transform code: incorrect value relationModifieder
2568 Added 'show all' command for yaz-client which retrieves all results
2571 Added new yaz-client, xmles, which takes a (private) OID and
2572 a document to be sent as an extended service request.
2574 Describe new yaz-client commands wait_response and set_auto_wait.
2576 Increase TCP/IP listener backlog from 3 (which I am guessing was
2577 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2578 that the socket will queue as many incoming connections as it's able
2579 to handle ongoing connections. In other words, it will never now
2580 refuse a connection that it would be able to handle merely because
2581 it's not got around to accepting() enough of the pending connections
2582 yet. This is the behaviour anyway under Linux, where the listen()
2583 argument is ignored; but not under BSD and on systems such as
2584 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2585 YAZ-based servers should now be uniform across operating systems in
2588 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2589 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2590 This allows yaz-marcdump to read large MARC batches (>2 GB).
2592 Modified all YAZ source files - except the source which is auto-generated
2593 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2596 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2597 corresponding to the existing *_setl() function. These allow option
2598 values containing arbitrary valuues.
2600 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2601 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2602 except that it returns an indicator of whether or not the sort
2603 criterion was accepted (0 for OK, -1 for invalid).
2605 --- 2.1.8 2005/06/07
2607 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2608 MARC output rather than returning "new" buffer.
2610 yaz-client warns about unknown init options.
2612 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2614 --- 2.1.6 2005/05/24
2616 Added support for SRW sort in Generic Frontend Server. Patch
2617 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2618 sortKeys - or NULL if none is provided.
2620 Fixed bug #307: It was impossible to specify indefinite/no timeout
2621 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2624 Added support for multiple languages and charsets to be specified in
2625 ZOOM. Each charset/language is separated by a blank. If negotiation is
2626 in effect in init-response, Option
2627 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2628 Code based on patch by Vasiliy Osadchuk.
2630 Fixed bug #306: infinite recursion that occurred when calling
2631 yaz_log_level_init as the first call (before other log level or
2634 Fixed bug in scan handling in front end server: if preferred-Position-In-
2635 Response was non-present, a NULL pointer referece was performed.
2637 --- 2.1.4 2005/04/26
2639 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2640 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2641 now defined for all those error codes. So instead of putting 109 in
2642 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2643 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2645 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2648 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2650 Program yaz-client now exits and produces an error message if multiple
2651 Z39.50 servers are specified on the command line (none or one allowed
2654 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2657 --- 2.1.2 2005/03/16
2659 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2661 Fixed bug #272: Preserve spacing for CCL terms.
2663 --- 2.1.0 2005/03/14
2665 Added support for virtual hosts and multiple backend servers for
2666 the YAZ frontend server. The configution is XML based and
2667 support specificition of CQL to RPN mappings and explain information.
2668 See section "Virtual Hosts" in the YAZ manual.
2670 Extended OPAC display utility. OPAC display utility renders
2671 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2672 to supplement yaz_marc_decode_wrbuf.
2674 Fixed a bug in MARC decoder that could caused it to crash for some
2675 invalid MARC records. More diagnostics and warnings where added in
2676 XML output (warnings, etc are stored in comments).
2678 --- 2.0.34 2005/02/08
2680 Fixes for UNIX domain sockets. Bug #261.
2682 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2684 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2685 Added yaz_marc_subfield_str which defines subfield lead string which is
2686 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2687 yaz_marc_endline_str which defines end of fields string used in
2688 YAZ_MARC_LINE format. Default string is newline.
2690 Experimental support for MarcXChange. This format can be produced
2691 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2692 http://www.bs.dk/standards/MarcXchange.xsd
2694 Added yaz-client commands scansize that sets maximum number of
2695 entries to be returned by scan.
2697 --- 2.0.32 2005/01/11
2699 Added support for SRW scan in yaz-client and Generic Frontend Server.
2701 * Added whereInList member to SRW Scan Term.
2703 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2705 Fixed NMEM system to return aligned blocks on the smallest boundaries
2706 that are suitably aligned for all possible types on the particular
2707 architecture YAZ is being built for.
2709 --- 2.0.30 2005/01/04
2711 Fixed numerious warnings that was issued with newer versions of GCC.
2713 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2714 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2717 Make YAZ Generic Frontend Server slightly faster.
2719 Enhance (and reduce) logging for Generic Frontend Server.
2721 Revert YAZ log system so that it flushes every write operation
2722 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2724 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2725 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2726 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2727 will effectively disable old definitions.
2729 --- 2.0.28 2004/11/09
2731 Added yaz_log_time_format which specifies log format using
2734 Added yaz_log_module_level which returns mask for a module. Value
2735 is non-zero mask a if module is enabled; zero if disabled.
2737 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2738 in include/yaz/cql.h.
2740 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2742 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2744 Fixed bug #172: RPM builds does not enable SSL.
2746 Doxyfile.in part of dist. Doxyfile generated by configure.
2748 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2749 are given and the corresponding component does not exist.
2751 Extend CCL documentation in YAZ reference. Describe r=r.
2753 --- 2.0.26 2004/10/01
2755 Fixed MARC->MARCXML conversion to properly deal with
2756 fields, subfields, indicators having non-ASCII characters.
2758 Fixed MARC->MARCXML conversion so that ASCII control characters
2759 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2762 Added YAZ GFS support for conversion from Z39.50 surrogate
2763 diagnostics to SRW surrogate diagnostics.
2765 Bug fix: YAZ GFS did not return schema in explainResponse.
2767 --- 2.0.25 2004/09/30
2769 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2770 now converts recordSchema to elementSetName as well as schema URI.
2772 Fixed bug in COMSTACK that prevented HTTP request packages from being
2775 --- 2.0.24 2004/09/29
2777 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2778 does not require white-space before and after the dash in a range, e.g.
2779 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2782 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2783 due to new GCC removing "redundant" code.
2785 Added yaz-client commands scanpos and scanstep that sets preferred
2786 position and step-size for scan.
2788 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2790 Added CCL utility ccl_qual_buf which parses one or more CCL
2791 spec lines in a buffer.
2793 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2794 of name and value - ignoring empty lines and comments.
2796 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2798 Added odr_get_element_path which returns current element path for an
2799 ODR handle. This utility is useful in error handling or user-defined
2802 Added ODR_PRINT utility odr_set_stream which is is a more generic
2803 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2804 to a write function and pointer to close function. The close function - if
2805 non-NULL - will be called during odr_destroy.
2807 Fixed bug in CCL parser where truncation char was not removed from
2808 right side when truncation=both was in effect.
2810 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2813 --- 2.0.23 2004/08/11
2815 Fix buffer overrun in CQL parser when dealing with proximity (%).
2817 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2818 to UTF-8/UCS conversion is now only based on codetables.xml.
2820 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2822 --- 2.0.22 2004/08/06
2824 Add support for more "commit changes" in ZOOM (uses Extended Services).
2826 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2829 Yet another small fix for configure of SSL.
2831 --- 2.0.21 2004/05/14
2833 Fix SSL libs for configure when --with-openssl=DIR is given.
2835 --- 2.0.20 2004/05/10
2837 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2839 SSL comstack now uses yaz.pem certificate file on server side
2840 by default. Certificate filename can be configured by calling
2841 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2843 Fix bug regarding multiple calls to ZOOM_connection_connect.
2845 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2847 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2848 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2850 ZOOM now allows inspection of X509 peer certificate for verification.
2851 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2853 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2854 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2855 as "modular" but it simplifies things.
2857 Added cs_get_peer_certificate to that returns peer X509 PEM.
2859 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2860 NULL if SSL is unavailable.
2862 Documentation about MARC decoding tools.
2864 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2866 --- 2.0.19 2004/03/30
2868 Rename CHANGELOG to NEWS to follow GNU style packing.
2870 Fix bug with missing initialization of member in init_diagnostics.
2871 This bug affects threaded version of GFS server.
2873 --- 2.0.18 2004/03/20
2875 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2878 Ensure zlib.dll is packed with Windows install.
2880 --- 2.0.17 2004/03/17
2882 Fix encoding of xsd:string to use text instead of CDATA.
2884 Fix endless loop in CQL parser with unbalanced ".
2886 Use a more compact way to store MARC-8 conversion tables.
2888 --- 2.0.16 2004/03/16 Debian only
2890 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2893 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2898 --- 2.0.15 2004/03/01
2900 Another fix for decoding of XML packed records.
2902 --- 2.0.14 2004/02/25
2904 Fixes for Chunked encoding. White space not ignored after length spec.
2906 Update NS and use default NS for SRW diagnostic elements.
2908 --- 2.0.13 2004/02/23
2910 Implement ZOOM_resultset_cache_reset which resets record cache.
2912 Implement ZOOM_resultset_sort which sorts a result set.
2914 Implement chunked HTTP transfer.
2916 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2918 --- 2.0.12 2004/02/16
2920 Added member 'schema' to bend_explain_rr structure so that backend
2921 can specify explain record identifier. Defaults to Zeerex 2.0.
2923 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2925 --- 2.0.11 2004/02/16
2927 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2930 Added init command for yaz-client which sends "extra" init request.
2932 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2933 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2935 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2937 Make ZOOM error code for "invalid query".
2939 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2941 --- 2.0.10 2004/02/05
2943 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2946 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2948 Added option -p <file> to make Generic Frontend Server to write PID file.
2950 Added option -D to put Generic Frontend Server in background on its own.
2952 Make ZOOM C recognize option "password". If unset, "pass" is used
2953 (for backwards compatibility).
2955 Fixed a bug in Generic Frontend Server that could make it crash if a
2956 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2959 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2960 Must be issued before open, in order to be in effect.
2962 --- 2.0.9-6 2004/01/12 Debian/Windows
2964 Make the SRU server more picky WRT unknown params, etc.
2966 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2968 New YAZ client command, options, that sets Z39.50 options.
2970 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2971 options from a string of tokens (one token for each option bit).
2973 Update SRW diagnostic code messages.
2975 --- 2.0.9-5 2004/01/07 Debian/Windows
2977 Handle user defined stylesheet for SRW/SRU.
2979 --- 2.0.9-4 2004/01/06 Debian/Windows
2981 Fix bug in decoding of Content-Length.
2983 --- 2.0.9-3 2004/01/06 Debian/Windows
2985 Fix a bug with decoding of XML packed records.
2987 --- 2.0.9-2 2004/01/05 Debian only
2989 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2991 Fix bug in SRW/SRU diagnostics decoding.
2993 --- 2.0.9 2004/01/05
2995 Fixed bug in Generic Frontend Server which could drop records exceeding
2996 preferred message size. Reported and fixed by Irina Dijour.
2998 Fixed calculation of package size for structured records in Generic
2999 Frontend Server. Reported and fixed by Irina Dijour.
3001 Fixed namespace for SRW/SRU diagnostics.
3003 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3005 --- 2.0.8 2003/12/22
3007 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3008 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3011 CQL changes to reflect recent changes to the specification:
3012 * Documentation talks about context sets instead of index sets.
3013 * Documentation talks about indexes instead of qualifiers.
3014 * The CQL-to-PQF transformer's configuration file now uses
3015 "index.set.name = <attributes>" instead of the old form
3016 "qualifier.set.name = <attributes>". (Both forms are still
3017 understood but the latter is deprecated.)
3018 * CQL terms with no explicit index specified are now interpreted as
3019 cql.serverChoice instead of srw.serverChoice (which of course
3020 behaves exactly the same.)
3022 --- 2.0.7 2003/12/16
3024 MARC conversion can now generate ISO2709 output in another
3025 character set. yaz-marcdump uses this facility if you invoke it
3028 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3029 functions from there can be used from C++.
3031 --- 2.0.6 2003/12/04
3033 Frontend server now transfers memory from decoded packages to stream
3036 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3037 references to show up.
3039 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3040 the ZOOM Abstract API. The older names for the same options are still
3041 also supported for the benefit of old applications.
3043 ZOOM-C supports "implementationId" and "implementationVersion" options
3044 to go along with "implementationName". These allow the user code to
3045 specify identification strings to be sent to servers.
3046 Add OID for the new ExtLite attribute set.
3048 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,

3051 For generic frontend server, reverse the order of
3052 "toolkit-supplied / application-supplied" strings sent as implementationId,
3053 Name and Version. Also, remove the spaces around the slash. This brings
3054 the GFS in line with the behaviour of ZOOM-C on the client side.
3056 Add function ZOOM_scanset_display_term.
3058 yaz-client shows scan displayTerm if present.
3060 Utility yaz-iconv is now installed by default along with the man page
3063 Extend configure check for OpenSSL to use pkg-config where available (such
3066 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3067 server to specify uid/gid/mask for socket using the format
3068 unix:[user=uid,][group=gid,][umask=mask,]file=path
3069 If file= is omitted the existing format is assumed, e.g.
3071 in which case the mask is 0666 (rw for everybody).
3073 Major restructure of YAZ source. All source in libyaz is in src directory.
3074 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3075 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3077 Added man page for utility yaz-marcdump (used to be called marcdump).
3078 yaz-marcdump is installed by 'make install'.
3080 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3081 of incoming package failed.
3083 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3085 Change prototype of odr_perror: add const to message string.
3087 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3089 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3090 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3091 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3092 DNS lookup. There should not be any compatibility problems with this
3093 assuming that blocking=1 or 0 is used.
3095 Fix bad reference in UNIX comstack in function cs_addrstr.
3097 Fix for compilation on AIX.
3099 The generic front-end server (server/seshigh.c) now supports returning
3100 Init diagnostics to the client in User-information-field, in
3101 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3104 --- 2.0.4 2003/09/04
3106 Allow any CQL relation (not just all,any,exact,scr).
3108 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3109 that features the same UI.
3111 Implemented command update0 in YAZ client which is equivalent to
3112 update but uses old of Ext Update ASN.1.
3114 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3115 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3116 Previously no OID was used for this info.
3118 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3119 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3120 returns 'malformed search term' otherwise.
3122 SortResponse member resultCount now set to NULL in sort handler of
3125 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3128 Add three new utility functions for translating OIDs between various
3129 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3130 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3131 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3132 char *oid_to_dotstring(const int *oid, char *oidbuf);
3133 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3135 Reverted modifications for ES Update definition for z_IU0Update
3136 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3137 is back to YAZ 2.0.2.
3139 String value attributes for CCL parser.
3141 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3142 which their FirstSearch server returns in Init responses, sometimes
3143 carrying useful diagnostic information when Init fails. This has the
3144 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3145 "z39.50/oclcui.asn", where its definition is somewhat different from
3146 what OCLC document on their web-site, as required to interoperate with
3149 Support for anonymous authentication in yaz-client. Use the command
3152 * Fix the OID of the Index Data-local "admin" Extended Service from
3153 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3154 the 1000, which indicates a locally-defined OID, was a mistake.
3156 --- 2.0.3 2003/06/20
3158 Fix CCL directive @case handling so that it affects string match for
3159 both CCL keywords and qualifiers.
3161 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3162 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3163 Decoder has been updated with ASN.1 changes as listed in
3164 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3165 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3166 z_IUUpdate, remains unchanged.
3168 ZOOM_record_get may now return a record in a specific character set.
3169 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3170 "from" is the character set of record as returned by target. "to" is
3171 the character set to be returned. If omitted, "to" is UTF-8.
3173 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3175 New ODR utility, odr_getelement, which returns name of element for
3176 which encoding/decoding failed.
3178 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3179 in cases where a required element was omitted.
3181 Bug fix: some MARC8 sequences were not converted.
3183 New ZOOM option "step" which specifies number of records to be
3184 retrieved in one chunk. Used in conjunction with "start" and "count".
3186 SRW support for yaz-client. Use scheme http: to use it, e.g.
3189 yaz-client no longer does (un)intelligent character set conversions
3190 by default. Can be enabled with charset and marc_charset commands.
3192 xmalloc trace fix for 64-bit systems such as DEC alpha.
3194 Solaris 2.6 compile fix.
3196 New function, cql_strerror() translates SRW error codes, as returned
3197 by cql_transform_error(), into human-readable English strings. Used
3198 in yaz-client diagnostics when appropriate.
3200 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3201 converts it into a type-1 query which is sent to the server. This
3202 makes CQL available for use with all Z-servers, as opposed to the tiny
3203 minority that can handle CQL queries themselves.
3205 --- 2.0.2 2003/04/28
3207 New Debian package layout similar to the Redhat Package layout.
3209 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3210 and search result respectively.
3212 --- 2.0.1 2003/04/25
3214 Redhat package is now several packages: libyaz (runtime libraries),
3215 libyaz-devel (development and documentation, and yaz (utility programs).
3216 Package spec file by Morten Bogeskov.
3218 New member 'schema' in struct bend_fetch_rr which the name of requested
3219 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3220 handler MAY set this to reflect the schema of the returned record.
3222 New member 'display_term' in struct scan_entry. GFS now sets member entries
3223 and allocates scan entries to be filled by user scan handler. In previous
3224 version, entries member was allocated by the scan handler. That still works,
3225 but the GFS will ignore member display_term - assuming it was NOT set by
3226 the handler. The fact that the GFS now allocates the entries both allows
3227 for new members and makes a scan handler easier to write.
3229 Fix CQL lex buffer overflow.
3231 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3232 SRU default recordPacking is string.
3234 SRU protocol support for frontend server.
3236 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3238 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3240 Added scan for the ZOOM shell (zoomsh).
3244 * String Identifers for Schemas (Amendment 5).
3245 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3246 Old definition for schema
3247 Odr_oid *schema; /* OPT */
3252 Z_InternationalString *uri;
3253 #define Z_Schema_oid 1
3254 #define Z_Schema_uri 2
3257 * resultCount parameter to Sort Response (Amendment 1).
3258 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3260 Support for SRW 1.0 over HTTP. This is an optional feature and
3261 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3264 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3265 on the same port. SRW SearchRetrieveRequests are mapped
3266 to bend_init,bend_search,bend_fetch,bend_close.
3268 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3270 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3271 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3273 ZOOM connections are SRW based if schem http is used for hostname
3274 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3275 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3277 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3278 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3279 distance=n, order=true/false, relation=le, prox unit=word. If
3280 n is omitted, distance 1 is used.
3282 Fixed problem with C compiler include path in wrong order.
3284 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3285 on Solaris. Patch from Ko van der Sloot.
3287 New MARC decode API. All new functions operate on a yaz_marc_t
3288 handle. The most important new functions are: yaz_marc_create,
3289 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3290 decode and destroy respectively. Decoder can produce formats
3291 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3292 include/yaz/marcdisp.h.
3294 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3295 to UTF-8, UCS-32, wchar_t or Latin-1.
3297 * Prototypes for yaz_iconv_-functions moved to separate header
3298 include/yaz/yaz-iconv.h.
3300 Make a few private functions 'static' in unix.c. This prevents
3301 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3303 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3304 are set when Init Response is received.
3306 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3307 but returns diagnostic set as well.
3309 New function yaz_strerror which is a portable wrapper for
3310 strerror/strerror_r/GetLastMessage.
3312 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3313 is returned for MARC. If type is "oai", then OAI MARC is returned.
3315 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3318 --- 1.9.2 2002/11/26
3320 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3322 Fix bad race conditions on SIGTERM and terminate gracefully in
3325 Move retrieval (data1) module to Zebra since nobody seems to be
3328 Add GRS-1 render for ZOOM using same format as yaz-client.
3330 --- 1.9.1 2002/10/05
3332 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3334 Fix broken ESpec handling in data1 module.
3336 SGML reader parses comments and makes them part of the data1 tree.
3338 Added several type casts so that YAZ compiles as C++ code.
3340 ZOOM didn't handle PDU encoding failures properly.
3342 Added more Bib-1 diagnostics (approved extensions).
3344 GNU configure: better check for iconv.
3346 More portable use of accept, getpeername. Check for socklen_t. Use
3347 int/size_t if socklen_t is not defined.
3351 PQF parser rejects bad queries - including those with extra
3352 characters in them. PQF parser used to silently ignore that.
3353 Cleaner API for PQF added, which allows you to get detailed
3354 error information for bad queries (see yaz/pquery.h).
3356 Fixed bug in ZOOM_record_get for type "database".
3358 Implemented mini iconv library supporting conversions between
3359 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3361 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3363 --- 1.8.9 2002/08/20
3365 Fixed ZOOM C record cache so that preferredRecordSyntax and
3366 elementSetName is used to check for already fetched records.
3368 --- 1.8.8 2002/08/02
3370 Added three members in bend_initrequest structure to facilitate
3371 character set negotiation.
3373 Fixed a bug in frontend server that could cause indefinite
3374 loops under rare conditions.
3376 Revised character set utilities (charneg.h) so that encoding
3377 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3379 For PQF, directive @term <type> sets term type for Scan/Search.
3380 Here <type> is general, string, numeric, null. The term type
3381 is inherited - just like @attr.
3383 New call odr_set_charset that sets character set conversion for
3384 international-strings on a ODR stream. Prototype is:
3385 int odr_set_charset(ODR o, const char *to, const char *from);
3386 The InternationalString is still represented as C string in YAZ
3387 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3388 won't). On the protocol level, you can use any encoding.
3390 Support for UNIX sockets in ZOOM.
3392 Solaris recv sometimes returns errno == ENOENT. It is treated as
3393 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3395 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3396 both client and server. Code by Morten Bogeskov.
3398 --- 1.8.7 2002/05/22
3400 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3401 that they can be used directly from Visual Basic. You must recompile
3402 your windows APP if you're using ZOOM.
3404 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3405 Commands "lang" and "charset" sets language and character set respectively.
3406 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3407 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3409 Attributes from multiple CCL fields may be OR'ed rather than merged
3410 using directive "@field or". Fields are still merged by default -
3411 equivalent to "@field merge".
3413 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3416 Fixed bug in zget for parameter ExtendedServicesResponse.
3420 --- 1.8.6 2002/03/25
3422 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3424 Client displays USR.1:SearchResult-1 (hits per term).
3426 Additional Search Info for search in Generic Frontend Server.
3428 Fixed CCL parsing of "field=s".
3430 WIN32 installer - using the excellent NSIS software from nullsoft.
3432 Fixed CCL parsing of "field = - <number>".
3434 Added function yaz_marc_decode that decodes MARC for line mode
3435 display or XML (similar to that used by JZKit).
3437 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3438 Z39.50. But ISO/ILL was, however.
3440 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3441 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3443 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3444 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3446 --- 1.8.5 2002/02/03
3448 New YAZ client features: Command completion and new commands:
3449 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3450 Code provided by Jacob Poulsen.
3452 New call oid_trav, that visits all registered OIDs via callback.
3454 Function ZOOM_record_get now returns const char pointer rather than
3455 void pointer. It saves a lot of type casts.
3457 For YAZ client, command "auth" now allows you to set authentication
3458 in IdPass style. It is enabled when three tokens are given - order
3459 is user, group and password.
3461 Fix memory leaks in MARC record handling for ZOOM.
3463 New option for YAZ client, -k <kilobytes> that sets
3464 maximum record size. Similar to -k option for generic frontend
3465 server and yaz-ztest.
3467 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3469 Prefix query parser reports "fail" when bad attribute set is given.
3471 Fix in MARC decoder. Proximity logging. Fix for attribute set
3472 in scan handler for server. Patches by Shigeru Ishida.
3474 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3477 Configure option --with-openssl=<dir> now works when a directory is
3478 specified. Patch provided by Morten Bogeskov.
3480 New option for YAZ client, -u <auth>, that sets authentication.
3482 ZOOM fix: error information was sometimes "missing", since error
3483 was cleared/reset too when it shouldn't.
3485 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3487 --- 1.8.4 2002/01/04
3489 Scan for ZOOM API. New object ZOOM_scanset. New functions
3490 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3491 ZOOM_scanset_destroy.
3493 New ZOOM function, ZOOM_connection_last_event, that returns type
3494 of last event (such as "receive data", "send data", "apdu received",
3497 New ZOOM option, schema, that specifies schema for retrieval.
3499 New CCL feature. Qualifiers can be aliases for one or more
3500 other qualifiers (if more than one is given, OR is used).
3502 ZOOM uses named result sets if target supports it.
3504 Two new YAZ client commands: . (dot, which sources a script of YAZ
3505 client commands), and ! (to execute shell command.). Implemented
3508 Working on Debian packages.
3510 --- 1.8.3 2001/11/19
3512 YAZ client enables named result sets only if target supports it.
3514 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3516 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3517 with key="host" to get same result.
3519 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3520 Function Z3950_resultset_record(s) returns references to records
3521 "owned" by resultset. To become owner use Z3950_record_clone.
3523 Function z_ext_record handles Extended Services. Thanks to
3526 --- 1.8.2 2001/11/12
3528 CCL Parser fix: ignore token comma when dealing with and-lists.
3530 Documentation updates for COMSTACK.
3532 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3533 Changed prototype Z3950_records. For some functions, int parameters
3534 were changed to size_t.
3536 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3539 New MARC decode/display function, marc_display_exl, which properly rejects
3540 non-ISO2709 records. YAZ client uses it.
3542 --- 1.8.1 2001/10/29
3544 Fix bug: local attribute set wasn't set correctly in PQF strings.
3548 * Old Z39.50 codecs no longer supported.
3550 Added ZOOM C binding. See http://zoom.z3950.org/
3552 Renamed states for COMSTACKs to avoid confusion with events.
3554 Implemented cs_look and proper cs_rcvconnect.
3556 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3558 Configure detects POSIX threads on OpenBSD.
3560 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3561 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3563 When error is returned from present handler, non-surrogate diagnostic
3564 is returned in present response (and fetch handler is no longer called).
3566 * Minor adjustments to pquery parser (PQF). Token characters may be
3567 escaped by using backslash (C-style).
3569 PQF parser allows string attribute values to be specified. For @attr,
3570 non-numeric characters after the equal-sign are treated as strings
3571 (e.g. @attr 9=title).
3573 CCL trunction character may be defined (@truncation in file)
3575 * function zget_ExtendedServicesRequest sets waitAction to
3576 waitIfPossible (was wait).
3578 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3581 CCL operator names may be set in field definition files (CCL_bibset).
3582 See ccl/bib1 for an example.
3584 Fixes in ASN.1 compiler for C++ compatibility.
3586 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3587 and "op_or" to avoid conflict with C++.
3589 Fixed problem with GNU readline detection on Redhat 7.0.
3591 Added step-size for Scan backend handler.
3593 Fixed bug that made the frontend server crash when no attribute
3594 set was specified for scan.
3596 Front-end server automatically switches to original working directory
3597 when installed as an NT service. Previously -w had to be specified to
3600 Added extended attributes for retrieval module (data1), so that data1
3601 records carry d1_readXML/SGML attributes. d1_read also supports
3602 null-data rules ( <tag/>)
3604 On UNIX when POSIX threads are available, a separate library libyazthread
3605 is created. Programmers should link with that library and the yaz library
3606 when using threads. The reason for the split was that some applications
3607 on Linux, such as Apache, doesn't work well when using shared objects that
3610 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3611 (or any frontend server) in SSL mode by specifying ssl: followed by
3612 address. Only tested on UNIX.
3614 Added feature for CCL module. Virtual structure s=al or s=ol generates
3615 and-list and or-list respectively instead of phrase search.
3619 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3620 log_mask_str. This was done to avoid name conflicts with other libraries
3621 (such as other PHP extensions).
3623 Added raw OID member for preferred record syntax (request_format_raw)
3624 and returned record syntax (output_format_raw) for backend fetch method.
3626 Config file yaz-config now accepts options so that it returns specific
3627 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3629 Shared library support for UNIX using GNU libtool.
3631 * Modified backend interface. Request/Response struct's replaced by
3632 one read/write C struct. For example bend_fetchrequest and
3633 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3634 Every handler - even search has to be registered in bend_init
3635 handler. This means that the YAZ library no longer refers to
3636 external functions and it makes it possible to make the whole
3637 thing a single DLL/SO.
3639 Added Segment handler for backend server.
3641 Added Zmbol/Zebra administrative functions to YAZ client.
3643 Threaded frontend server on UNIX (when POSIX Threads are available).
3644 Starting the server with option -T enables multi-threading.
3648 Added configure option --enable-comp/disable-comp to control use
3649 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3650 located in sub directory asn.
3652 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3653 in ${exec_prefix}/bin along with the other programs yaz-client and
3656 GNU automake used to maintain makefiles.
3658 Added several OID's.
3660 Changed retrieval module so that we can load records with no abstract
3661 syntax defined. Tagpaths in these records are fully composed of string
3664 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3668 On UNIX, the generated makefile now supports a proper 'make install'.
3669 The prefix can be set via GNU configure to set the install location
3670 (default is /usr/local).
3672 * YAZ programs client and ztest were renamed to yaz-client and
3673 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3674 locations, such as /usr/bin,/usr/local/bin,etc.
3676 * YAZ Header files were moved from include to include/yaz. YAZ Header
3677 files are referred to as include <yaz/log.h> rather than <log.h>.
3678 The YAZ include path (-I ..) is therefore the same as before. Programmers
3679 should update their #include statements or use -Ipath/include/yaz
3680 instead. The main motivation for doing this change is that YAZ header files
3681 can be installed in "standard" locations /usr/include,/usr/local/include
3682 without introducing conflicts, since ALL YAZ header files are stored
3683 in subdirectory yaz (under /usr/include for example).
3685 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3686 rather than project/workspace files. We switched because project files
3687 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3690 Changed name of logging function, logf, to yaz_log, to prevent name
3691 clash with some math-log functions. The YAZ header log.h defines logf
3692 to yaz_log (#define) so there should be no incompatibilities by this
3695 Added bend_start/bend_stop handlers for server. These handler are
3696 called on start/stop of server. For windows they are called whenever
3697 a service is started/stopped.
3699 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3700 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3701 in util/yc.tcl. The auto-generated C code structures are, in a few
3702 cases, incompatible with the old decoders. There are differences in the
3703 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3704 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3705 The preprocessor variable ASN_COMPILED is defined when the compiled
3706 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3707 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3708 wish to use the old encoders/decoders you can specify --disable-yc
3711 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3712 version so that it supports both new - and old version of DB Update
3714 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3715 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3716 change. The name parameter can be set to 0 in which no name is specified
3717 for the construction. The macros odr_implicit and odr_explicit sets name
3718 parameter to zero for the construction involved. New macros
3719 odr_implicit_tag and odr_explicit_tag are similar to the others,
3720 except that a name parameter is added. For programmers' that don't use
3721 ODR they probably only need to change the call to z_APDU and z_External.
3723 Added access control facility by interfacing the TCP wrapper library.
3724 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3725 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3726 name of the daemon and enables the access control as specified in
3727 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3729 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3730 den Dool <H.M.vdnDool@kub.nl>.
3732 Added reference ID parameter to most functions in server API - refer
3733 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3735 Changed name of ccl library to libccl.a (was ccl.a).
3737 Fixed bug in decoder for Explain (Category TargetInfo).
3739 Added support for GNU readline in client. Thanks to Jacob Poulsen
3740 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3742 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3743 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3744 IMPLEMENTATION! This change was made to the development version before
3745 the ZIG decided to retract the amendment. If any users MUST be
3746 compatible with the original Update definition, PLEASE CONTACT US, and
3747 we will include a separate definition corresponding to the old Update
3748 ES. Note that because of the change to the ASN.1 of the
3749 TaskPackageRecordStructure we cannot define a single structure that
3750 will support both versions.
3752 * Added const modifier to buffer parameter for some ODR/BER encoding
3753 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3754 completeWAIS, odr_dumpBER.
3756 Fixed bug in client.c which caused a crash when a scanResponse didn't
3757 contain positionOfTerm.
3759 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3760 * will cause an error in a client if a non-YAZ target sends both a
3761 * list of Scan entries and non-surrogate diagnostics.
3763 Retrieval module enhancements. Tag sets may be typed in the reference
3764 to it. From the .abs-file the "tagset" directive takes a third optional
3765 integer type for the tag set referenced. From a .tag-file the "include"
3766 directive takes a third optional type as well. The old "type" directive
3767 in the tag set itself is still recognized but acts as the default type
3770 Backend interface change. Individual Scan terms returned from bend_scan
3771 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3772 in include/backend.h.
3774 Retrieval module enhancements. Multiple tag sets and attribute sets may
3775 be specified in abstract syntax specs. Revised the error/warning for
3776 logging messages reported by the retrieval module when reading the
3779 Object Identifier system (oid_..) changed. The API is backwards
3780 compatible but the oid-routines now allocates new OID's when needed.
3781 Raw OID's may be specified in oid_getvalbyname.
3783 YAZ now uses GNU configure to generate Makefile(s).
3785 * Minor changes in some of the member names of DeleteResultSetRequest and
3786 DeleteResultSetResponse. See include/proto.h.
3788 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3789 and added member 'languages' in TargetInfo (which was missing).
3791 Changed the way attribute sets are handled in the retrieval
3792 module. These are now cached, just like the abstract syntaxes
3795 Changed YAZ so that it links with compiled ASN.1.
3797 Added Explain-schema definitions and mapping routines. The following
3798 Explain categories have been implemented: AttributeDetails,
3799 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3801 Fixed minor bug in Windows version of Server Library.
3803 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3805 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3807 Added EXTERNAL: UNIverse Resource Report (non-standard).
3809 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3810 ENUMERATED and SET OF.
3812 * Added 'const' to some of the char pointer arguments for the
3813 functions, data1_read_node, data1_getelementbytagname,
3814 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3817 Fixed bug in data1_insert_taggeddata - the last_child member of
3818 parent wasn't initialised.
3820 * Changed data1_read_record and data1_read_node so that the supplied
3821 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3822 doesn't refer to any parts of the "SGML"-buffer.
3824 Fixed bug in server library (Windows version of statserv_remove).
3826 * Changed code so that it compiles as C++. The type definition
3827 of Odr_fun which is a member of Odr_arm was changed. The result is,
3828 that an explicit typecast is needed for the fun pointer when
3829 using Odr_arm - as in:
3830 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3832 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3834 Implemented the new structured date and time definition as approved
3835 by the ZIG. Added schemaId element to the specificTag in Espec-1
3836 (also approved at the last ZIG). Thanks to RVDM.
3838 Added some Object identifiers (RVDM).
3840 Changed the Update Extended Service (RVDM).
3842 Added command "refid" to client which specifies referenceId for
3843 the following requests.
3845 Implemented extended service handling for server. See ztest.c
3846 for an example as well as backend.h. New handlers are registerd
3847 in the Init handler.
3849 * Changed interface for sort in server.
3851 Added new members to statserv_options_block. It allows a server
3852 to read options from another source than just the command line. Thanks
3853 to Charles Woodfield.
3855 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3856 renamed to zboolean. Some C++ compilers complained about the name.
3858 Minor changes to gils.abs. Added index 's' (sort) on title
3859 and date/time-last-modified.
3861 --- 1.4pl2 1998/1/30
3863 Fixed bug in server library regarding inetd mode (-i). This bug
3864 was introduced by release 1.4.
3866 --- 1.4pl1 1998/1/29
3868 Added sort facility in client and backend server interface.
3870 Fixed problem with dependencies in Makefile(s).
3872 Fixed bugs for encoders/decoders of extended services and
3875 Implemented sub-tree feature for schemas. Sub-trees are
3876 referenced in *.abs-files. See explain.abs for an example
3877 of the use of this feature.
3879 Modified bib1.att; local attributes for ANY didn't include
3880 ANY itself (only affects use of the retrieval module).
3882 Fixed bug in plain SGML reader in function data1_read_node:
3883 tags with prefix "var" was incorrectly interpreted as variants.
3885 Added feature "sub-schemas" to enable references to - and definitions
3886 of - group of elements.
3888 * Removed member parent from type data1_element (in data1.h).
3890 Implemented function odr_nullval() that returns the value of
3893 * Removed member num_children from data1_node (in data1.h).
3895 Made NT service interface part of the server library. The
3896 function statserv_main uses the NT service when required and
3897 calls the statserv_start / statserv_close routines.
3899 Routine zget_SearchRequest and zget_PresentRequest fills
3900 resultSetName/Id member with "default" instead of "Default".
3902 Fixed memory leak in server. Request queue member wasn't freed.
3904 Fixed nmem_exit so that memory is freed.
3908 Revised the CCL parser utility to be thread safe.
3910 Added function, oid_ent_to_oid, to replace the function
3911 oid_getoidbyent, which is not thread safe.
3913 * Added nmem_init and nmem_exit to initialize and release
3914 NMEM resources. Function nmem_init should be called once in the
3915 initial thread before NMEM/ODR is used. statserv.c and client.c
3916 have been changed accordingly. The change was necessary to make
3917 NMEM thread safe. The NMEM memory pool is shared amongst threads
3918 in a process. Unix-based applications will still work fine without
3921 Added NT Services interface for the the Z39.50 (statserv) Server.
3922 Refer to the ztest.c source on the usage.
3924 Windows 95/NT port using MSVC5.0. Project files are included in the
3927 * Defined new 'global' handle for the retrieval (data1) system. The
3928 new handled, data1_handle, describes the state of the data1 system.
3929 This handle is passed as first argument to virtually all
3930 data1 related routines. The functions data1_create and data1_destroy
3931 creates and destroys a data1 handle respectively.
3933 Added ODR encode stream member to all backend request structures
3934 init, search, scan etc. This stream should be used to allocate all
3935 memory used for the response when thread safe operation is needed.
3937 Changed the comstack utility, cs_addstr, to be thread safe. The
3938 returned hostname string returned by the function is now part the
3941 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3942 function. The cs_straddr takes a COMSTACK handle as argument, so this
3943 function must be used after cs_create and before bind/connect.
3944 This function is thread safe.
3946 Moved test server to 'ztest' directory - generic server code still
3947 in 'server' directory.
3949 Made prefix query (pquery.c) utility thread safe.
3951 Added new function modifier YAZ_EXPORT to 'export' public DLL
3952 functions when using windows (see include/yconfig.h).
3954 Added definitions to the OID database (util/oid.c) (RVDM).
3956 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3958 Added call to ccl_rpn_delete in client program.
3960 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3961 release of RPN structure.
3963 Added support for C++, headers uses extern "C" for public definitions.
3964 With input from RVDM.
3966 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3967 Thanks to Ronald van der Meer (RVDM).
3969 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3971 Added support for private extensions to the OID database
3972 (oid_setprivateoids()). Thanks to RVDM.
3974 Added optional, physical ANY (key replication)
3976 Fixed null-reference problem in GRS-1 output filter.
3978 Proximity operator added to Prefix Query Format (PQF).
3980 In test client command "base" accepts multiple databases.
3982 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3986 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3988 Smallish bug-fixes in the new encoders/decoders (explain).
3990 Bug fixed in DeleteRequest.
3992 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3994 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3996 Added SOIF syntax (using private OID for now) to retrieval module and client.
3998 Added Update extended service.
4000 Added SearchResult-1 additional info structure.
4002 Added optional CCL (ISO8777) interpreter as separate module. Available
4005 --- 1.2 1996/6/10 (1st anniversary release)
4007 Added Summary record syntax. Lightly tested.
4009 Added OPAC record syntax. Untested.
4011 Added ResourceReport service encoders/decoders. Untested.
4013 Fixed bug in z_Unit - wrong tagging on unitSystem.
4015 Fixed bug in the DiagRecs decoder.
4017 Added options for max PDU size and session timeout to frontend-server.
4019 Added documentation of query-language parsers and other supporting utilities.
4021 [frontend-server] Added Attribute set to the bend_scanrequest API.
4023 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4024 surrogate diagnostics were generated.
4026 [retrieval] Allow multiple local values for attribute.
4028 [retrieval] Allow multiple attributes per element in .abs files. index type.
4030 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4032 --- 1.1pl2 1996/4/10
4034 Minor changes, mostly specific to Zebra's requirements (retrieval)
4038 Repaired bug in frontend server when running multiple listening
4039 endpoints in dynamic mode.
4041 z_External() now won't break if a known, ASN.1 value comes encapsulated
4042 in an octet-string. The value will pass through unmodified in an Odr_oct.
4044 Added a bit of code to the demo client to decode & display
4045 ASN.1-structured records represented in the octet-aligned branch of
4046 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4048 Added z_ext_getentbyref() to the ASN module. Doc updated.
4050 * Completed the SCAN definition in the ASN module. This may break SCAN
4051 code based on older YAZ-versions at compile-time. The fix is easy -
4054 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4055 under the SCAN definition. Remember to initialize this, server-people.
4057 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4058 that this does not extend to ODR and ASN.
4060 Comstack allows insertion of established socket (primarily for
4061 inetd-operation of servers). Doc updated.
4063 Front-end server can now start from the inetd in TCP mode. Doc
4066 --- 1.0pl4 1996/1/24
4070 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4071 the rank and record number.
4073 Adjustments to the frontend server.
4075 Fixed diagnostic BER dumper. It ignored the file argument.
4079 Various changes to retrieval module.
4081 Changed the union discriminators of the protocol files from enums to
4082 ints paired with #defines.
4084 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4087 *Changed operator in the RPN structure to 'roperator', again to avoid a
4090 Fixed problems in Explain decoders/encoders.
4092 --- 1.0pl2 1995/12/6
4094 Memory bug in log module fixed.
4096 --- 1.0pl1 1995/12/5
4098 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4100 Bug in Explain DatabaseInfo module fixed.
4102 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4106 The shift to v1.0 signals that we now consider the *core* functionality
4107 of YAZ reasonably stable (the core being more or less equivalent to
4108 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4109 tested (Explain not at all - though that will happen soonish).
4111 Minor changes to code to support Windows port.
4113 Various minor changes after we're getting to use GRS-1 & co. more.
4115 Added Espec-1 format.
4117 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4118 of the protocol and it cannot be selected when encoding (maps into 'string'
4119 when decoding). Needed to talk to some servers.
4121 Demo client can request simple element set names.
4123 Added Diagnostic Format encoders/decoders.
4125 Added simple Close handling to frontend server (no hooks for resource
4126 reporting yet), and demonstration client.
4128 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4130 --- 1.0b3 1995/08/24
4132 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4133 handled incorrectly when records were requested in the searchResponse. This
4134 will only affect you if you use the frontend-server.
4136 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4137 Test-client will ask for and print GRS1. Ztest will return dummy records
4140 Added Explain encoders/decoders to the service-level API. Untested.
4142 Added Extended Services: Item Order encoders and decoders to the Service-
4143 level API. Untested. We could use a recent copy of the pertinent bits
4144 of the ILL protocol to add those bits.
4146 Added diagnostic format 1 encoders/decoders to the service-level API.
4149 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4150 odr_cons.c, which causes a more correct output.
4152 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4153 was always set to 0 when no records were requested in the searchRequest.
4155 * Added better external-handling. This shouldn't harm old code that
4156 *encodes* externals. It can break code that looks for a
4157 'single-ASN1-type' representation, since those types that are known
4158 are now decoded immediately. Look at the SUTRS sample code in
4159 seshigh.c and client.c. Documentation updated.
4161 Handling of structured records in bend_fetchresponse. Length -1 marks
4162 structured record, type is deduced from format field.
4164 --- 1.0b2 1995/06/27
4165 Fairly quick maintenance release to add SUTRS support.
4167 Fixed handling of SUTRS records in the demonstration client.
4169 * Added format field to the bend_fetchrequest and bend_fetchresponce
4170 structures of the backend API (frontend server). When the record is
4171 returned, the value of the format field is mapped to an OID. The
4172 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4173 of the record. The special value VAL_NONE in the bend_request means
4174 that no specific format was requested by the client. Documentation
4175 updated accordingly. Test server (ztest) will return a fixed dummy
4176 SUTRS record if your client requests SUTRS.
4178 Documentation updated accordingly.
4180 You can now set external libraries and RANLIB support in the top-level
4184 First public release.
