5 ZOOM C: tweak when connection failed is returned
6 For cases with multiple socket addresses for some hostname, eg
7 localhost IPV4+IPV6, the code now properly returns "connection
8 failed" rather than "connection lost".

72 Fix ZOOM: crash extended services diagnostics YAZ-846
73 The immediate fix is to prevent ZOOM_set_dset_error from removing
74 current task from connection. This, however, has been assumed in a
75 number of places so this fix is rather large unfortunately.

155 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
156 Introduce cs_create_host2 which returns if connection should be
157 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
158 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).

203 Try to fix the situation where parent process stops before
204 child has acknowledged it .. SIGUSR2 back!
206 daemon: log message when keepalive stops.
210 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
211 would make yaz-marcdump crash when from-character set was issued.
215 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
216 New function yaz_enable_panic_backtrace which enables backtrace
217 handler for current process. The handler will call backtrace always,
218 then gdb to provide as much detail as possible.
222 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
223 and ZOOM record render will inspect leader 9 and switch to UTF-8
224 (Unicode) if that holds 'a'. This changes behavior, but is considered
225 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800

272 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
274 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
276 CCL YAZ-779: combo qualifier should allow for forward references
278 Fix buildconf.sh, automake too old on centos5 YAZ-778
279 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
280 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
281 accepts it without a warning.
285 GFS: client_query_charset conversion YAZ-777
286 This is a feature for Z39.50 clients that sends queries that are not
287 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
288 encoding given to UTF-8.
290 Echoed SRU arguments support YAZ-776
291 This is achieved with new function yaz_srw_get_pdu_e.
293 ZOOM: expire times set for redis/memcached YAZ-772
294 For both redis and memcached option --expire=seconds sets expire
295 time for a result-set/search. Default time is 600 seconds (10 minutes).
299 No [rest of output is omitted] limit for yaz_log YAZ-774
301 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
303 For ICU testing, pass -o to yaz-icu. This will test the
304 icu_iter_get_org_info function.
306 Fix null ptr reference for freeReplyObject YAZ-773
310 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
312 RPM: do not build with libmemcached support. The libmemcached library
313 on CentOS 5/6 does not work reliably for us (redis to the rescue).
315 configure: only allow libmemcached version 0.40 or later. That's the version
316 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
317 that's not an option, consider redis.
321 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
323 Fix zoom+memcached: present request out of range YAZ-767
327 CCL: add new qualifier r=omiteq which will omit relation=equals
328 for ordered relations. This should be used in combination with either
331 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
333 Solr: simplify yaz_solr_decode_response
335 Solr: use different local var for string manipulation

351 wrbuf_buf: make it always return non-NULL
352 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
356 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
358 zoomsh: offer option -a apdulog
359 As we're used to from yaz-client and GFS based servers.
361 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
362 existing setting apdulog takes effect.
364 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
369 Add re-entrant CQL/Solr/RPN query conversion functions.
370 The re-entrant functions are: cql_transform_r,
371 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
372 These have same functionality as cql_transform,
373 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
374 return the additional infomration as WRBUF to make them re-entrant.
376 Remove CQL to Solr conversion and base solr_transform_t on
377 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
378 data structure as cql_transform_t.
380 cql2pqf utility allows RPN to Solr conversion

390 yaz_log_init_file may take fd=<no> to open log file at the FD given.
392 --- 5.0.21 2014/03/21
394 Offer new utility function zget_AttributeList_use_string.
396 New conversion step, solrmarc, for record conversion module.

404 --- 5.0.19 2014/03/10
406 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
407 The standalone ZOOM sort was completely broken since 5.0.13.
409 ZOOM: generate event Connect rather than None for partial connect
410 (in fact getaddrinfo resolving).
412 ZOOM: only supply clientIP for InitRequest. Rather than for all
415 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
417 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
418 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
419 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
421 New "Facets" section in the documentation.
423 --- 5.0.18 2014/02/27
425 Call exsltRegisterAll in yaz_init_globals, so that all applications
426 using YAZ will have EXSLT things enabled.
428 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
430 Update various URLs to the re-organized SRU pages at LoC.

434 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
435 introduced in 5.0.12.
437 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
438 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
439 Do not call yaz_init_globals from log_mask_str_x. Problem introduce

448 Fix gcrypt not properly initialized YAZ-740.
450 --- 5.0.14 2014/02/19
452 Describe memcached option for ZOOM.
454 ZOOM: throw present request out of range again YAZ-739
455 Was removed in YAZ 5.0.13.
457 --- 5.0.13 2014/02/18
459 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
460 with localtime_r when threads + fork is used (such as Metaproxy).
462 yaz-config: quote some RHS values (that might include blanks)
464 zoomsh: shows SearchResult-1
466 zoomsh: sortby command
468 zoomsh: use proper list of connections and result sets YAZ-725
470 Avoid yaz_log in sigterm handler for GFS YAZ-737
471 Logging is still performed, but outside sig handler.
473 New ZOOM C feature: result-set caching with memcached. Example:
474 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
476 Remove SSL via OpenSSL support YAZ-732
477 Also deprecate two functions from comstack that aren't working with
478 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
480 Revert "Bison: use %name-prefix directive rather than -p option"
482 --- 5.0.12 2014/01/22
484 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
486 SRU GET/Solr base URLs may hold additional ?args YAZ-729
487 ZOOM option extraArgs already does this, though. It seems useful
488 when dealing with Solr targets to limit by filter, eg.
489 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
491 Remove #fragment for HTTP request encoding YAZ-730
493 Doc: Update list of DLLs/LIBs
495 Doc: update href link to Unix utils and Git.

499 ZOOM: fix "lost connection" problem with servers that uses both squid
500 and another proxy behind it that returns Location headers with relative
503 zoomsh: do not use readline for stdin (no tty) YAZ-724
504 Just use fgets in that case. If the user hits Ctrl-D a new-line
507 zoomsh: empty command ignored YAZ-723
508 rather than performing exit of zoomsh.
510 yaz-url utility offers option -v to enable verbose mode.
512 yaz_url uses yaz_check_location and offers verbose mode.
514 Add new function yaz_check_location.
515 This function gets an absolute URI from Location (HTTP redirect).
517 cookie API: introduce yaz_cookies_reset
519 Update cql.y for newer bison YAZ-720
520 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
521 longer supported. Instead one must use %lex-param and %parse-param .
523 --- 5.0.10 2014/01/09
525 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
528 rpn2solr: support truncation left(2), left&right(3) YAZ-718
530 Mention SRU version 2.0 in yaz-client man page.
534 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
539 Make cs_parse_host public.A
541 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
542 introduced in YAZ 5.0.6.
546 Fix buffer corruption for yaz-ztest record fetch.
550 Allow yaz-ztest to return user-defined records (one record per file).
551 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
553 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
554 Use the stream write instead of odr_printf which has a 4K tmp buffer.
556 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
560 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
561 can read and write this format. For record format JSON, yaz-ztest returns
562 MARC-in-JSON records.
564 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
565 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
569 Improve error reporting for ICU chains YAZ-707
570 Report config element+rule when ICU status is "failure".
572 ZOOM: stop fetching if present response has no records YAZ-710
573 Some targets return less records than their hit count would suggest.
574 This prevents ZOOM from continuing to fetch records if any present
575 response has 0 records in the response.
577 Ensure that GFS calls exit if any listener fails YAZ-710
578 Before, if XML config was in use, it would start the default
583 yaz-ztest: -V shows version (like yaz-client -V)
585 New iconv encoding: danmarc YAZ-692
587 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
589 daemon: only wait for immediate child rather than all children. YAZ-704
591 yaz-client: fix setting of SRU record schema. If scheme was unset, it
592 could lead to invalid memory reference.
596 yaz-ztest returns schema for MARCXML test records. SRU require that
597 recordSchema for records.
599 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
600 instead of non-surrogate diagnostic. This is a per-record failure.
602 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
603 may refer to multiple listeners now. Attribute listenref is a comma separated
606 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
607 option is given for GFS, the dirname of filename (for -f) is used
608 as prefix for options such as cql2rpn, ccl2rpn, etc.
610 Content-Type charset fixes YAZ-701 . Do not inspect charset in
611 Content-Type header for SOAP when decoding SRU. The payload (XML)
612 itself tells what encoding it is. In response, never supply encoding
613 in Content-Type. The response payload (XML) tells what it is (with no
614 encoding in XML it's UTF-8).
616 HTTP decoding: allow blanks in URL paths YAZ-700
620 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
621 and facets. Ensure recordData and recordSchema are always present in
622 record element, because they are required.
624 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
627 Simplify in a lot of places using odr_strdupn.
629 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
633 Increase various buffers in GFS's statserv_options_block
634 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
635 This change makes many type-casts redundant, and, thus simplifies code.
637 Remove last bits of WAIS support.
639 Remove member 'size' from Odr_oct.
641 Slim down the public part of 'struct odr'. Most elements are not part
642 of struct Odr_private.
644 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
645 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
646 In particular facets are supported in both client - and server side.
647 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
648 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
649 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
650 both request/response). This is what a search handler in the GFS
651 will see (regardless of whether operating in SRU mode or Z39.50).
653 Changes to the srw.h (SRU/Solr) definitions include:
654 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
655 (char*), which replace union query and query_type (int). This is because
656 SRU 2.0 supports a queryType parameter. This also means that, to carry
657 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
658 x-pquery=PQFstring (extention parameter). The extension parameter
660 - New element, packing, that has information about SRU
661 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
663 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
665 New element, packing, in Z_SRW_explainRequest.
667 New elements in Z_SRW_scanRequest, queryType and scanClause.
668 These replace query_type and scanClase untion. This is similar to what
671 --- 4.2.69 2013/10/01
673 GFS: log when closing down - at least SIGTERM YAZ-684
674 Also change formatting WRT PID logging a bit.
676 Improve display of MARC records with multi-byte subfield IDs YAZ-695
677 In some rare cases subfield identifiers are multi-byte characters.
678 This will try to deterime length of those and split accordingly.
679 This affects display in line mode as MARCXML/MarcXchange. The encoding
680 of ISO2709 is the same.
682 Change inp argument to const for yaz_read_UTF8_char.
684 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
686 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
688 Better check of marc leader info YAZ-691
689 Problem is that some systems generate MARCXML/MarcXchange with
690 funny headers. These will not work if encoded as ISO2709.
691 Some tests produce new output, due to updated warning messages
693 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
695 yaz-client: display MAB records YAZ-689.
696 Thanks for Heiko Jansen for this patch.
698 New utility z_get_HTTP_Response_server which allows both HTTP server name
699 and HTTP server URL to be given in response.
701 Debian: do not depend on obs tcl8.3.
703 Debian: do not depend on obs libicu36-dev.
705 --- 4.2.68 2013/09/23
707 GFS: pass additionalSearchInfo to search memeber search_input if
708 given. Otherwise pass otherInfo. Request for facets and other search
709 related things will be passed there in future versions of YAZ.
711 New ZOOM setting, authenticationMode, which allows authentication
712 paramters to be encoded in the URL rather than via HTTP Basic auth.
715 rpn2solr: fix nested AND/OR handling. YAZ-685
717 Add comparison routines for some Z-types, such as NamePlusRecord,
718 RPNQuery, Query, RecordComposition and OtherInformation.
720 --- 4.2.67 2013/09/19
722 Don't decode MAB as MARC. Just like we don't attempt to decode
723 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
725 CCL: allow quoted terms for date ranges. YAZ-681
727 Introduce ccl_parser_qual_search. This function makes old function
728 ccl_qual_search, from YAZ 2, available again.
730 Add yaz_facet_list_to_wrbuf. YAZ-683
732 --- 4.2.66 2013/09/11
734 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
735 schema was given for search. YAZ-675
737 Add Solr date range searches. YAZ-621
739 --- 4.2.65 2013/08/22
741 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
743 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
745 ISO2709/MARC parse most octet aligned records; not just those that
746 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
747 MARC parse more records instead of just dumping as is. YAZ-670
749 ZOOM: proper caching for variations of record schema. YAZ-671
751 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
753 --- 4.2.63 2013/07/17
757 --- 4.2.62 2013/07/11
759 New utility z_get_HTTP_Response_details - an extended version of
762 New utility yaz_url_get_error which returns error message of last
763 failed yaz_url_exec call.
765 yaz-url and url functions: allow max HTTP redirects to be controlled.
767 New functions yaz_file_glob2, yaz_xml_include_glob.
768 These functions takes a flags parameter, which, for now only controls
769 whether to fail inclusion of a non-existing file (without glob
770 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
772 --- 4.2.61 2013/06/20
774 For MARC XML parsing, allow record without leader. A fake/default leader
775 is inserted and a warning is tagged with the record.
777 ICU: fix leak in in icu_iter_get_org_info.
779 --- 4.2.60 2013/06/14
781 ICU: fix bug in icu_iter_get_org_info (un-init variable).
783 --- 4.2.59 2013/06/11
785 Implement z_HTTP_header_remove.
787 --- 4.2.58 2013/06/11
789 ICU: Disallow 0 ptrs for some ICU string utilities.
791 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
792 returns original tokens (before normalization).
794 CCL: avoid z39.58/regex truncation when not needed. Apply only the
795 conversion of those masks, when absolutely necessary.
797 CCL: configurable masking character - @mask. Default masking character
800 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
801 full response anyway, so a Transfer-Encoding header will obstruct the
804 --- 4.2.57 2013/05/15
806 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
807 picking a socket. Problem is that some systems has IPV6 support, but
808 we can't create sockets for them, so we pick AF_UNSPEC first.
810 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
811 use content_len to determine resulting Content-Length in HTTP response
812 and NOT Content-Length supplied in headers by user.
814 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
815 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
817 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
820 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
821 with big endian and unsigned char (by default).
823 --- 4.2.56 2013/04/26
825 Fix yaz-client connect (crash in 4.2.55).
827 --- 4.2.55 2013/04/26
829 Fix proxy/host problem for ZOOM that could occur if unix sockets
832 New Debian package libyaz4-dbg.
834 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
835 differently in tcpip_close.
837 --- 4.2.54 2013/04/17
839 Windows installer of YAZ includes YAZ4J as a component.
841 CQL: allow "extra terms" again, by default. Thus, the CQL parser
842 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
843 and earlier. CQL parser may operate in strict mode where queries
844 not conforming to the standard BNF are rejected (syntax error).
845 Whether the CQL parser operates in strict mode is controlled with
846 cql_parser_strict . Strict mode enabled with option -S for utilities
847 cql2pqf and cql2xcql .
849 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
851 --- 4.2.53 2013/04/10
853 New charset, MARC-8c, which is like MARC-8 but allows control characters
854 0x01 through 0x1F, except ESC to be passed through verbatim.
856 Fix a problem with duplicate sub field character in MARC output. Problem
857 happened only when output was MARC-8 encoded.
859 --- 4.2.52 2013/04/03
861 yaz-ztest: Use hash for fake hit count. Before, random number was used.
862 This is problematic for unit tests using yaz-ztest. This patch also makes
863 a hash for CQL queries. For RPN, any term with a leading digit will be
864 treated as pseudu hit count (to force any particular hit count by a client).
866 yaz-ztest: return unique MARC dummy records. Beyond record offset
867 24, the author surname is patched with offset to make all records
870 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
871 on system wide default (/proc/sys/net/ipv6/bindv6only).
872 @4 binds to IPV4 only. @6 binds to IPV6 only.
874 Update CQL API documentation a bit
876 CQL: don't accept extra terms for queries. Makes the CQL parser
877 stricly conformant to the standard.
879 --- 4.2.51 2013/02/12
881 GFS: scan handler gets extra_args from request and may return extra
882 response data . That's for SRU only.
884 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
886 --- 4.2.50 2013/01/30
888 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
890 OPACXML: sync spelling of availabilityDate in XML to that of Schema
891 opaxxml.xsd. The schema had the correct spelling of this member always.
892 The ASN.1 was mis-spelled and still is (API change) - we are
893 not changing this. However, the OPAC to XML conversion had yet
896 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
899 New function, z_ext_record_oid_nmem, which is similar to
900 z_ext_record_oid but takes NMEM rather than ODR
902 --- 4.2.49 2013/01/18
904 ICU: New conversion element 'join' which joins tokens into one
905 with a custom character given by rule attribute.
907 --- 4.2.48 2013/01/10
909 New GFS search member: present_number. This is a hint to the
910 search handler how many records are going to be fetched immediately
911 following search. There's no guarantee that it's going to be the case,
912 since it depends on hit count (for Z39.50 piggyback) and whether errors
915 Make a few functions static (private). The functions getbyte_stream,
916 ungetbyte_stream and yaz_gets are now private. They were never declared
919 yaz-marcdump: exit(5) for serious decoding errors
921 ISO2709 decoding: be more picky WRT header
923 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
924 was only used as to indicate that next-result-set-position should be
926 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
927 Based on patch from Ashley Sanders.
929 Make some functions static/private in PQF parsing. Those functions were
930 never declared in a public header and so should not be in use by
931 applications based on YAZ.
933 --- 4.2.47 2012/11/23
935 ZOOM: special options to control APDU logging.
936 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
937 logging of APDUs until "saveAPDU" option is set again. If logging is
938 already enabled the effect is that current APDU buffer is cleared.
939 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
940 logging (default behavior on new connection).
941 The APDUs sent/received can be obtained by using
942 Using ZOOM_connection_option_get(c, "APDU") or
943 ZOOM_connection_option_getl(c, "APDU", &l).
945 GFS: relay implementation_version from backend
946 From 3.0.40 and later, implementation_version from backend was
947 not used in init response at all.
949 --- 4.2.46 2012/11/15
951 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
952 mode at all. Probably never did.
954 Make a new version of ztest.pem that, at least, is not expired.
956 --- 4.2.45 2012/11/13
958 Fix description of CCL directive 'case'.
960 More tight checking of form arguments (yaz_uri_to_array). Makes
961 YAZ better at rejecting big and/or bad POSTs.
963 SRU decoding does not report more than up to 10 invalid arguments.
965 rpn2cql: less quotes in generated terms. Semantics unchanged, but
966 it's prettier this way.
968 --- 4.2.44 2012/10/25
970 New utility yaz_decode_init_diag. Defined in proto.h.
972 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
973 given for unix local socket.
974 The COMSTACK string for doing so is:
977 unix:/myfile:tcp:localhost:9999/mybase
978 unix:/myfile:localhost:9999/mybase
979 unix:/myfile:http://fakehost/mybase
981 debian: Use dpkg-buildflags in build process.
983 --- 4.2.43 2012/10/19
985 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
986 global's SRU service uses a recordPosition scheme starting from zero.
987 First record's position should be one
988 according to the standard.
990 --- 4.2.42 2012/10/18
992 Allow more namespaces for SRU. This is to allow, for example, an
993 incorrect namespace returned from server
994 http://services.igi-global.com/sru .
996 Minor fixes for compilation on Windows.
998 --- 4.2.41 2012/10/11
1000 daemon: log total number of bad signals from child on stop so that it
1001 is more easy to spot problems with child worker processes.
1003 retrieval: empty backend name attribute omits element set
1004 from being used in retrieval.
1006 --- 4.2.40 2012/10/04
1008 Implement Solr sort strategy "solr", similar to sru11 sorting.
1009 This will implement the correct parameters on Solr requst to do
1012 --- 4.2.39 2012/09/28
1014 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
1017 MARC: Extra/missing indicator handled for MARCXML.
1018 The indicator length is given in header and is the same for the
1019 whole record. If attributes ind1, ind2 are missing, then content
1020 character defaults to blank. Extra indicator attributes (beyond)
1021 indicator length are treated as an error.
1023 Reformat: delete trailing whitespace
1025 --- 4.2.38 2012/09/17
1027 MARC: fix non-ASCII characters for leader. This is to ensure we can
1028 generate XML in UTF-8.
1030 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
1031 in one node with structure word.
1033 --- 4.2.37 2012/09/04
1035 yaz-json-parse: JSON output may be pretty printed by using option
1038 Increase default value of max message for Z39.50 Init for GFS, ZOOM
1039 and yaz-client. Old value was 1 MB. New value is 64 MB.
1041 --- 4.2.36 2012/08/22
1043 yaz-client: don't display bogus records from SRU servers. Some SRU servers
1044 return more records than given by *maximumRecords*. Skipping those in
1047 record_render: simplify buffer return handling and fix at least one bad
1048 memory reference, that broke the test_embed_record sometimes.
1050 Allow http://user:pass@host notation for yaz_url_exec.
1052 zoomsh: allow shell command to be executed. Via the system(3) call.
1054 yaz_poll: Allow num_fds == 0
1056 yaz-client: fix bad encoding of "itemorder item". The itemorder
1057 item <no> - command forgot to use length of encoded Item Request
1058 package. Error present since YAZ 3.
1060 yaz-ztest: fix bad usage of session handle. Bug was introduced when
1061 result sets were saved (271a9c83).
1063 SRU recordPacking: guess record packing in response rather than looking
1064 at the recordPacking element which, OF COURSE, changed semantics in SRU
1067 Decode SRU 2.0 responses. The official namespace for responses, according
1068 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
1069 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
1070 nature.com's server, however, usee namespace
1071 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
1072 we are now using a glob-expr to match up the namespace. ZOOM C and
1073 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
1074 I can not find a single real example showing the "real" namespace in
1075 the documentation from OASIS. The namespace for requests is different
1076 from responses, but this is not added to YAZ yet, when we don't encode
1079 --- 4.2.35 2012/06/26
1081 zoom/record_render: add support for Base64 decoding fo MARC records
1082 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
1083 which will decode base64 + ISO2709 marc-8 encoded material from text node
1086 --- 4.2.34 2012/06/07
1088 Add missing definitions ZOOM_resultset_get_facet_field_by_index
1089 and ZOOM_resultset_facets_names.
1091 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
1094 Change APDU dump printing to avoid long leading blanks. For levels 16
1095 or larger the level is shown and the indentation is truncated but
1096 recursed with modula 8. This makes it still reasonable easy to read
1097 - even for nested BER dumps.
1099 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
1100 return 0 (incomplete package) in case where the BER package was
1101 considered too nested (return value of -2).
1103 dumpber: lines of level 15 are not indented further. Two spaces per
1104 indentation; indentation 15 or more is indented to a fixed indentation
1105 and augmented with a level=<no> indication.
1107 zoomsh: increase max size of command+args
1109 GFS: No limit in RPN buf size in CQL to RPN conversion.
1111 --- 4.2.33 2012/05/09
1113 New function for daemon utility, yaz_daemon_stop .
1115 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
1117 --- 4.2.32 2012/04/25
1119 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
1120 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1122 --- 4.2.31 2012/04/23
1124 YAZ daemon utility relays SIGUSR1 to child process.
1126 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1127 would result in en empty database list - which in turn would result in
1128 encoding failure for search.
1130 Fix reading beyond string in yaz_sort_spec.
1132 --- 4.2.30 2012/04/11
1134 Add two new SRU diagnostics:
1135 236: Access to specified database denied
1136 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1138 Document the very useful ZOOM-C option "apdulog".
1140 CQL to RPN: term may be passed through verbatim. This is enabled with
1141 truncation.cql . The assumption being that the term is already CQL.
1143 --- 4.2.29 2012/03/20
1145 record_conv: leader spec may be given for marc element.
1146 The leader spec is given as attribute leaderspec for element marc.
1147 For example to convert a MARC21 record from MARC-8 to UTF-8:
1148 <marc inputformat="marc" outputformat="marc"
1149 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1151 record_conv: allow user-XSLT params. For example:
1152 <xslt stylesheet="MARC21slim2DC.xsl">
1153 <param name="myparameter" value="myvalue"/>
1154 <param name="otherparameter" value="othervalue"/>
1157 record_conv: fix error handling for missing marc charsets.
1159 CQL: fix extra terms in wrong order.
1161 --- 4.2.28 2012/03/06
1163 record_conv: modify new API for conversion types. The conversion types
1164 may be passed in new functions yaz_record_conv_configure_t and
1165 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1167 Avoid mixed statement/variable declare; fixes compilation with Visual
1170 --- 4.2.27 2012/02/28
1172 Add non-standard SRU diagnostic: 235: "Database does not exist".
1173 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1174 Update SRU to Bib-1 diagnostic maps accordingly.
1176 CCL: add two new diagnostics for unsupported masking. The new
1177 diagnostics are: "Embedded truncation not supported" and
1178 "Single charcacter mask not supported".
1180 --- 4.2.26 2012/02/23
1182 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1184 --- 4.2.25 2012/01/11
1186 Build YAZ for Ubuntu Oneiric.
1188 CCL: allow parantheses for proximity operands. For example CCL query
1189 (a) % (b) is now allowed.
1191 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1192 marked dead, rather then being destroyed. If not, the session memory is
1193 being free'd before the search/scan handler is finished. Also destroy
1194 'request' memory in request_release rather than in various places,
1195 which resulted in leaks from time to time.
1197 --- 4.2.24 2011/12/21
1199 cql_sortby_to_sortkeys: honor sort prefix.
1201 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1202 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1203 The rpn2cql family of functions now always returns quoted CQL terms.
1205 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1207 --- 4.2.23 2011/12/15
1209 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1210 sequence is treated as one. For example, &&a=b&&&c& is identical to
1213 --- 4.2.22 2011/12/05
1215 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1216 APDUs for a connection to a WRBUF.
1218 --- 4.2.21 2011/11/23
1220 Fix cql_sortby_to_sortkeys. Completely broken before.
1222 Make CCL's @truncation work again.
1224 --- 4.2.20 2011/11/09
1226 New ZOOM connection setting: tproxy. It's like proxy, but does not
1227 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1228 to set resolved address + port for a connection outside ZOOM itself.
1230 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1232 --- 4.2.19 2011/11/07
1234 Fix uninitialized variable in Solr spell support (could cause SEGV
1235 for SRU response decoding).
1237 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1238 back-end's addinfo through into the ZOOM response addinfo.
1240 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1241 they are separated by a colon and a space rather than simply
1244 --- 4.2.18 2011/10/28
1246 Add support for Solr spell-checking/suggestions through ZOOM.
1247 If a Solr target has been configured correctly for spelling-checking
1248 and suggestions, these will now be returned on the ResultSet option
1249 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1251 --- 4.2.17 2011/09/28
1253 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1254 with a flag whether to substitute escape sequences or not.
1256 --- 4.2.16 2011/09/22
1258 Fix nmem_strsplit_escape to substitute escape char properly.
1260 New option for zoomsh -e , which makes it abort on first error and
1261 return process exit code to indicate success/failure.
1263 YAZ options utility supports special option -- which makes all it treat
1264 all following arguments as non-options.
1266 --- 4.2.15 2011/09/16
1268 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1269 searched if absolute filename is given.
1271 Fix conv_xslt() error-reporting when stylesheet is not found.
1272 (The value of fullpath is meaningless in this situation.)
1274 --- 4.2.14 2011/09/07
1276 Fix problem in CQL sort node creation: un-initialized memory.
1278 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1279 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1280 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1283 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1284 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1286 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1287 will make it possible to use both single-character mask (#) and wildcard (?)
1288 in CCL . Throw diagnostic for left truncation because that is not supported
1291 --- 4.2.13 2011/09/01
1293 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1294 cases using escapes (\-sequences) and masking.
1296 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1297 would result in a read one byte beyond string.
1299 rpn2ccl may use Z39.50 masking for terms (t=z).
1301 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1303 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1304 not --cppflags (which seeems like an error in icu-config).
1306 --- 4.2.12 2011/08/27 RPM package only
1308 cql2ccl: fix conversion of terms: operator characters were not
1311 --- 4.2.11 2011/08/25 RPM package only
1313 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1314 CCL parser will map both # and ? to their regular expression
1315 quivalents (. and .*).
1317 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1318 of reserved CQL characters.
1320 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1321 is, so that they are passed through.
1323 --- 4.2.10 2011/08/24
1325 ZOOM SRU mode: more aggressive re-connect.
1327 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1328 made available as a utility function, declared in <yaz/logrpn.h>
1330 rpn2cql_structure() supports proximity nodes (except that the Type-1
1331 proximity node's "exclusion" binary is ignored, as there is no way to
1332 express that in CQL). Fixes bug #4564.
1334 --- 4.2.9 2011/08/18
1336 Fix SEGV that could occur if set command of zoomsh was given without
1337 value (2nd argument).
1339 Fix SEGV that could occur if unsupported transport was given for
1340 COMSTACK - say https (when SSL was unavailable).
1342 Build yaz-url on Windows too.
1344 --- 4.2.8 2011/08/11
1346 New utility to get web content. Header is url.h. A command line tool
1347 yaz-url is part of the distribution and packages.
1349 Fixes for SSL COMSTACK (when gnutls is in use).
1351 New functions yaz_base64{encode,decode}. Header is base64.h.
1353 --- 4.2.7 2011/08/03
1355 ZOOM C includes HTTP response buffer as additional info if it fails
1356 to decode the SRU response.
1358 Make wrbuf_json_puts available.
1360 --- 4.2.6 2011/07/28
1362 zoom: throw diagnostic for invalid value for option "sru". Before a
1363 bad SRU request was sent.
1365 Adding new utility wrbuf_vp_puts.
1367 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1369 --- 4.2.5 2011/07/21
1371 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1372 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1373 redirect was used at the same time.
1375 MARC line mode decoding: be less picky about length given - first
1376 5 digits of header that is.
1378 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1380 Changes to decoding of SRU records: a record with recordPacking=xml is
1381 modified with a new root element <yaz_record> if the recordData contains
1382 multiple children elements. This is to make the record XML parseable
1385 RPN to Solr conversion: encode special characters.
1387 Generic Frontend Server: fix uinitialized member, stepSize.
1389 --- 4.2.4 2011/06/21
1391 Fix a bug in SRU decoding of records.. The database records stored
1392 had un-initialized memory, but it would only be seen with yaz_record_render
1393 and type_spec="ext" .
1395 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1397 --- 4.2.3 2011/06/17
1399 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1401 --- 4.2.2 2011/06/10
1403 Add new utilities to convert from CQL to CCL . These utilities have
1404 prefix cql_to_ccl defined in cql.h.
1406 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1407 lead to memory heap corruptions when ICU utilities were in use.
1409 --- 4.2.1 2011/06/07
1411 Make compilation work without Libxml2.
1413 yaz-client: remove redundant blanks in display of searchResult-1 term
1416 --- 4.2.0 2011/05/18
1418 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1419 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1421 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1422 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1423 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1424 Note that the CQL sortby spec is only converted when the GFS is already
1425 converting from CQL to RPN (cql2rpn element).
1427 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1428 specify whether to collapse delimitors or not. The existing nmem_strsplit
1429 do collapse (collapse parameter = 1).
1431 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1433 Rename internal func yaz_use_attribute_create. While non-static, this
1434 function is not declared in a public header.
1436 --- 4.1.7 2011/03/15
1438 Add -lCrun when linking with ICU on Solaris.
1440 More quicks character set conversions for OPAC records.
1442 --- 4.1.6 2011/03/10
1444 fix problem with record_render: records were converted (character set
1445 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1447 --- 4.1.5 2011/03/08
1449 SRU: add methods for handling DADS SRU-proxy facets.
1451 Separate OPAC record character set for ZOOM_record. yaz_record_render
1452 allows a character set given as charset=from/opacfrom,to where 'from' is
1453 the character set of a bibliographic record, 'opacfrom' is character set
1454 of OPAC record and 'to' is the target character set.
1456 --- 4.1.4 2011/02/21
1458 yaz-client: show may XML format records. Command show followed by 'format'
1459 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1462 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1465 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1467 --- 4.1.3 2011/01/27
1468 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1470 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1471 this package can be distinguished from other vendors.
1473 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1474 as determined by configure
1476 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1478 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1479 returns no error and no record, the present request is considered
1480 partial (only a subset of the records could be returned by backend), and
1481 so it is appropriate to set Present Status to partial-4.
1483 --- 4.1.2 2010/11/02
1485 Move yaz-config man pages to section 1.
1487 More documentation about Solr.
1489 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1490 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1491 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1492 peers on some Linux systems. However, in general that does not work
1493 so YAZ can not rely on that to work. Debian changed behavior in this
1494 respect from Debian lenny to Debian squeeze (still testing as of Oct
1496 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1498 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1500 --- 4.1.1 2010/10/05
1502 Fix yaz-config output: echo_source not set correctly by configure.
1504 --- 4.1.0 2010/10/05
1506 Solr Web Service support for yaz-client and ZOOM.
1508 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1510 --- 4.0.12 2010/08/17
1512 Z39.50 facet support. Facet specifications are passed for search in
1513 other-information with ASN.1 as defined in facet.asn and OID
1514 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1515 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1516 3 is limit (number of entries to get in response). yaz-ztest returns
1517 dummy facets if a client asks for them.
1519 --- 4.0.11 2010/07/09
1521 CCL fixes: bug 2895 and bug 3539.
1523 GR1-display: add comma in display - was removed by mistake in
1526 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1528 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1530 --- 4.0.10 2010/06/18
1532 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1533 result set from a connection. The result set will be on its own
1534 thereafter; no operations on it will perform retrievals from a target.
1535 Only cached copies are returned.
1537 ZOOM C:fix case for HTTP servers responding with Connection:close.
1538 Ensure that if there is a current task it is resumed (like fetching
1539 more records in a result set) . Bug #3484.
1541 PQF parser: use odr_atoi for Odr_int (not atoi)
1543 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1544 values that contain any non-digits are treated as string attributes
1545 (previously decoding only checked for leading character ([0-9]). PQF
1546 encoding: attribute string values are not surrounded by double-quotes.
1548 --- 4.0.9 2010/05/21
1550 New utility for managing threads - thread_create.h.
1552 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1553 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1554 but YAZ' implementation do.
1556 Fixes for yaz_cond-functions on Windows 7.
1558 DLL export more symbols.
1560 zoomsh: show record do NOT render opac.
1562 Remove *.la files from Debian and RPM packages.
1564 --- 4.0.8 2010/05/11
1566 Debian package libyaz-dev depends on libgnutls-dev again (was
1567 removed in YAZ 4.0.6, but due to Libtool it is still needed
1568 even though yaz-config do not list libgnutls libs).
1570 ZOOM: Use only one WRBUF for returning string results for
1571 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1573 ZOOM: ZOOM_connection do not use a shared pointer to
1574 ZOOM_resultset after ZOOM_resultset is destructed by
1575 user. Reverts to YAZ 4.0.4 behavior.
1577 --- 4.0.7 2010/05/04
1579 record-conv: fix problem with at least one XSL conversion -
1580 due to probably incorrect usage of XML XSL documents.
1582 --- 4.0.6 2010/04/29
1584 Fix yaz-config for static mode and the use of SSL (gnutls).
1586 --- 4.0.5 2010/04/29
1588 Forward decl timeval struct in mutex.h and gettimeofday.h.
1590 yaz-config: fix 'static' mode linking.
1592 --- 4.0.4 2010/04/28
1594 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1595 are wrappers for pthreads or Windows. For Windows these are put in
1596 a separate DLL: yaz_cond4.
1598 libyaz.la (whole source) is compiled with thread. If thread support
1599 is enabled enabled, all source of YAZ is compiled with treading support.
1600 This allows core utilities such as yaz_log to use thread facilities.
1601 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1602 thread utilities. This commit moves mutex utilities (mutex.c) from
1603 libyaz_server.la to libyaz.la.
1605 yaz-json-parse displays leading text until error.
1607 --- 4.0.3 2010/04/09
1609 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1610 patch from Giannis Kosmas.
1612 SRU: no longer URL encode SRU database. The URL for an SRU server is
1613 a URL and such is alreeady encoded - at least when given with leading
1614 http:// or https://. This reverts behavior to YAZ 3.0.50.
1616 Support for new MARC XML notation TurboMARC which like MARCXML is a
1617 complete representation of MARC/ISO2709.. This one, however, is more
1618 compact and allows for faster processing with XSLT. TurboMARC can be
1619 used in the marcdisp.h API, from the yaz-marcdump utility and from
1622 yaz-ztest can be configured - via the database - to perform certain
1623 delays when it performs operations search, present and single record
1624 fetch. This allows testers to make yaz-ztest act as a real or even slow
1625 Z39.50 server. Refer to the yaz-ztest man pages for details.
1627 --- 4.0.2 2010/03/09
1629 wrbuf_destroy allows NULL WRBUF passed to it.
1631 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1633 Add ZOOM_connection_close.
1635 No fixed size buffers for ZOOM shell - bug #3257.
1637 tstodr: make it work on s390 platform.
1639 New icu iterator-functions. The new icu_iter-functions makes it possible
1640 to use ICU chains from many threads.
1642 yaz-client: better syntax check for show command.
1644 --- 4.0.1 2010/01/26
1646 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1649 New simple local-file XML include facility which allows file glob-patterns.
1650 Refer to yaz/xml_include.h.
1652 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1655 ZOOM_record_get supports new parameter "format" which makes it format XML
1658 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1659 JSONText in ECMA-262) is JSONValue, not JSONObject.
1661 --- 4.0.0 2010/01/20
1663 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1664 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1666 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1667 POSIX/Unix builds .so with major version 4.
1669 Remove old LOG_-defines from log.h. They have been obsolete and
1670 undefined by default for the last 5 years.
1672 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1674 GFS: Remove socket (int *fd) from search_rr handler. The socket
1675 descriptor ptr is a facility that allowed a search handler to supply
1676 a socket which would serve as a callback - when search was complete.
1677 This facility has now been in use for years.
1679 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1680 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1681 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1682 returns 'const char *' rather than 'char *. The returned string is
1683 read-only and should not be modified by applications. COMSTACK cs_close is
1684 now a void function - it no longer returns int. No applications check for
1685 the value and the implementations has always returned 0.
1687 ZOOM: use size_t for scan hit counts and str size. Functions
1688 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1689 occ (hit count) and len (string length) are now of type size_t pointer
1690 rather than int pointer. This is to be able to represent large hit counts
1691 and to also just to use the proper type for string length (strlen result).
1693 New JSON parser. Refer to include/yaz/json.h .
1695 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1696 Used to be int in some cases. Many wrbuf_-functions used to return an int
1697 indicating some length.. These return values were never used. And so they
1700 ODR: odr_malloc, odr_total now takes size_t for size.
1702 clone_z_type: fix leak; occurred for encoding failures.
1704 --- 3.0.52 2009/12/03
1706 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1707 bug was introduced in 3.0.51.
1709 --- 3.0.51 2009/12/02
1711 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1713 tcpip comstack: fix leak for getaddrinfo.
1715 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1716 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1717 Decoding of SRU "path" database is performed by private function
1718 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1719 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1721 yaz-client: honor base command for SRU. Change when database setting
1722 is applied for SRU and ensure it is kept when a connection is reset.
1723 Change also the way errors are displayed or SRU (decoding of packages).
1725 --- 3.0.50 2009/11/02
1727 Add support for extra request / response data for SRU codecs and GFS.
1728 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1729 for extra data response buffer and length. For the GFS, both request
1730 and response data (XML) is carried in extra_args and extra_response_data
1731 for the search handler. Patch by Ko van der Sloot.
1733 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1734 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1735 10010). This fixes bug #2113.
1737 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1738 cmdfile included a 'quit' command that would result in a memory violation.
1740 --- 3.0.49 2009/10/01
1742 Make a number of functions defined in xmlquery.c static. These have
1743 never been declared in a public header file (yaz/xmlquery.h) and was
1744 made public by mistake.
1746 Improve speed of character conversions (iconv utilities). This makes
1747 conversions from MARC-8 faster.
1749 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1750 unless type desired is "raw". This will prevent type "xml" from
1751 returning ISO2709 .. Which obviously can not be XML parsed.
1753 Fix memory leak in ZOOM that would occur if option apdulog was used
1754 on a re-used connection.
1756 Frontend server logs HTTP requests.
1758 Frontend server now sends Z39.50 close when it times out (sesssion has
1759 been idle for too long). Versions 2.0.30 and earlier also sent close.
1760 But due to a mistake this was disabled in all versions after that, i.e.
1761 the server would just close the socket immediately.
1763 yaz-client emits a better message when receiving an unrecognised
1764 userInformationField.
1766 Skip zero-length subfields when decoding ISO2709. This rare case happens
1767 if a record has two FS characters in a sequence. Without this patch
1768 there would be a reference beyond char array in using_code_len fragments
1771 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1773 --- 3.0.48 2009/08/28
1775 The show command offered by the zoomsh command now takes a 3d optional
1776 parameter type which is what is passed to ZOOM_record. If the type
1777 argument is omitted, "render" is used.
1779 RPN to CQL conv may use USE string attributes (bug #2978).
1781 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1783 --- 3.0.47 2009/07/08
1785 Function yaz_xml2query allows a diagnostic element in the PQF XML
1786 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1787 code and additional info respectively.
1789 The BER BOOLEAN is now the integral type Odr_bool which still happens
1790 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1791 typedef'd to Odr_int. This is still an integral 'int', but it may be
1792 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1793 ASN-1 compiler as well as programs has been updated to use the new types.
1795 --- 3.0.46 2009/06/08
1797 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1798 only the bibliographic record was rendered. For type=opac, an OPAC
1799 record is only returned if it is present.
1801 iconv: small fix for encoding of advancegreek.
1803 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1805 yaz-client: option auto_reconnect=on really reconnects.
1807 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1809 server: avoid null ptr ref for for yaz_poll errors.
1811 build: fix RPM build for RHEL 5.3.
1813 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1815 --- 3.0.45 2009/03/31
1817 Fixed bug #2709: TCP connect returns Invalid argument.
1819 Fixed compilation for mingw.
1821 Honor charset for raw records (ZOOM_record_get).
1823 Fixed use of errno for threaded mode that was seen on Solaris 10.
1825 Fixed argument passing with blanks in value for Windows Service.
1827 Disable YAZ' own log rotate by default (no 1 GB limit).
1828 The variable l_max_size which specifies the log file limit is set to 0
1829 (DISABLED): This is due to the fact that YAZ is most often deployed using
1830 logrotate. Also YAZ can not perform log rotate because of unsufficient
1831 permissions (setuid).
1833 --- 3.0.44 2009/02/17
1835 List supported encodings in man page for yaz-iconv.
1837 Fixed missing SSL libs for --libs output
1839 Re-established OID record syntax application-xml. Nobody should use it
1840 but we don't want to change soname because of this symbol being absent.
1842 --- 3.0.42 2009/02/02
1844 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1846 Added member named_result_sets for init handler struct for the GFS. This
1847 allows a server to disable named result sets.
1849 Removed OID record syntax application-xml.
1851 Added support for rule-based transliterator for ICU wrapper of YAZ.
1853 Fixed bug #1902: yaz-icu XML output.
1855 Make YAZ checks Emacs friendly.
1857 BITSTRING value shows value. Bug #2346.
1859 ISO2709 decoding: skip control characters from indicator data.
1861 Omit sort key by default in yaz-icu's output.
1863 Allow combined single char options (again) for YAZ' options function.
1865 Utility yaz-marcdump got option to display YAZ version (-V).
1867 Allow YAZ to use ICU 3.4.
1869 Added new ICU test case which illustrates removal of diacritics.
1871 --- 3.0.41 2008/12/29
1873 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1875 --- 3.0.40 2008/12/29
1877 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1880 Fixed bug #2352: yaz-marcdump crashes for certain record.
1882 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1884 Added support for Danmarc2 to UTF-8 conversion.
1886 Added support for ISO5426 to UTF-8 conversion.
1888 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1889 implementation version.
1891 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1893 --- 3.0.38 2008/11/10
1895 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1896 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1898 ZOOM C now interprets databaseName option for ZOOM connection as path
1901 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1903 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1905 Dummy Libxml2 types no longer defined in headers of YAZ'.
1907 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1910 --- 3.0.36 2008/09/26
1912 Various ODR chapter fixes.
1914 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1916 Added missing source for Windows compilation, mutex.c.
1918 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1920 For SRU connections in ZOOM all records up to "count" are now fetched.
1922 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1923 in Windows due to bad error handling for Libxml2.
1925 Added facility for sending arbitrary records (ASN.1 any) using
1926 ZOOM C's Extended service update. Patch by Sam Reynolds.
1928 New options for ZOOM C's connection, logapdu which makes ZOOM log
1931 --- 3.0.34 2008/06/18
1933 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1935 --- 3.0.32 2008/06/12
1937 Fixed memory violation that could occur when decoding UTF-8. This bug
1938 was only present in 3.0.30 of YAZ.
1940 --- 3.0.30 2008/06/06
1942 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1943 GNU TLS is used by default (if found).
1945 yaz-ztest returns OPAC records if a client asks for OPAC.
1947 Improved speed of MARC-8 encoding.
1949 Added support for lossy and loss-less MARC-8 encoding.
1951 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1953 Added new Windows Service wrapper (sc).
1955 yaz-client's itemorder command may now send a file.
1957 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1959 Added new function yaz_log_xml_errors.
1961 Allow (but warn) unknown XML attributes in MARCXML parsing.
1963 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1965 The UTF-8 to MARC-8 conversion now uses a different set of characters
1966 for Greek symbols. Bug #2120.
1968 --- 3.0.26 2008/02/21
1970 Added yaz_daemon (daemon.h).
1972 Fixed bug #2068: pkg-config trouble
1974 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1976 --- 3.0.24 2008/01/28
1978 Document --with-xml2 option.
1980 Added OPAC XML XSD (etc/opacxml.xsd).
1982 Allow glob mask for name attribute in retrieval element for the
1983 generic frontend server's retrieval facility.
1985 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1986 except POLLIN/POLLOUT.
1988 Fixed error handling in cs_listen. Bug #2037.
1990 --- 3.0.22 2008/01/20
1992 Fixed version in yaz/yaz-version.h.
1994 Fixed bug #2027: Crash when closing connection.
1996 Changed configure so that ICU support is only enabled if only ICU
1997 and Libxml2 is available (because the ICU chain is XML based).
1999 --- 3.0.20 2008/01/15
2001 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
2002 is built. Only this DLL depends on the ICU runtime.
2004 yaz-ziffy is no longer part of YAZ. It is distributed separately by
2005 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
2007 Changed license of CCL module to 'Revised BSD'. After consultation with
2008 remaining members of the original EUROPAGATE consortium, we are re-issuing
2009 the CCL module without a separate license. The software was developed by
2010 Index Data as part of a research project. The special license was included
2011 to help feed usage information back to the project consortium to support
2012 project evaluation. At this time, the project consortium has long-since
2013 disbanded, and the majority of the original principals have retired. At the
2014 same time, we have significantly modified the software during the following
2015 years, to the point where very practically no original code remains. To
2016 simplify re-use of the software, we have contacted those members of the
2017 consortium who could be reached, and agreed to re-issue the module as a
2018 proper part of the YAZ package.
2020 Tcl scripts uses /usr/bin/tclsh as preferred shell.
2022 CQL closer to being version 1.2 compliant. CQL also allows free-form
2023 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
2026 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
2027 bug could make Extended services handling crash in the ZOOM layer. This
2028 bug was only present in YAZ 3.0.18.
2030 --- 3.0.18 2007/12/19
2032 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
2035 yaz-marcdump reads and writes collection wrapped records.
2037 Handle OPAC for record conversion module.
2039 Fixes for ICU wrapper.
2041 Allow ICU libs to be controlled with --with-icu .
2043 --- 3.0.16 2007/11/12
2045 Added yaz_poll which is a wrapper for select/poll. When poll is available
2046 and non-buggy, it is used, by yaz_poll . This allows more than 1024
2047 sockets to be in use.
2049 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
2050 functionality through an XML based configuration (ICU chain). This system
2051 is useful for search facilities such as Pazpar2 and Zebra that needs to
2052 perform tokenization of indexed material. The ICU code in a separate
2053 library libyaz3_icu.a.
2055 Added HTTP tunnel facility for COMSTACK, bug #1752.
2056 This is a facility that allows a Web proxy, such as squid, to tunnel
2057 Z39.50 traffic. This facility is "transparent" to must applications
2058 using YAZ. It's enabled by using pseudo transport connect: followed by
2059 the proxy address, followed by command, then follwed by he regular
2060 "virtual" addresss. For example,
2061 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
2063 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
2065 --- 3.0.14 2007/09/21
2067 Fixed bad memory reference in ZOOM_record - cuased by member not being
2068 initialized. This was a problem only in YAZ 3.0.12.
2070 Fixed bug in conversion from MARC to XML: Non-XML characters in control
2071 fields were not removed.
2073 Changed the way C code is generated from codetables.xml. Made a MARC-8
2074 conversion trie for each characterSet section rather than codeTable.
2075 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
2076 of codetables.xml from Larry Dixson, LOC. Bug #1464.
2078 --- 3.0.12 2007/09/12
2080 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
2081 from ZOOM_record_error).
2083 ZOOM C function ZOOM_record_get returns record schema for type="schema".
2085 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
2087 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
2089 Better SRW-to-Bib-1 diagnostic mapping.
2091 ZOOM C and yaz-client announces SRU version 1.2 by default.
2093 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
2096 Fixed in yaz_sru_decode to allow other version than 1.1.
2098 --- 3.0.10 2007/08/22
2100 Added support for SRU scan for ZOOM.
2102 Added support for the use of the older versions or Extended Service
2103 Update in ZOOM. To faciliate this, an option "updateVersion" may be
2104 set to the version , 1=first, 2=second, 3=third. The third version is
2105 what ZOOM C has used so far. And that, obviously, is the default.
2107 Added support for CCL queries in Z39.50 queries sent to the GFS (and
2108 therefore in Zebra and in SimpleServer-based applications). The new
2109 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
2110 qualifier file used to transform incoming CCL queries into Type-1 RPN,
2111 which is passed into the back-end search callback function.
2113 Added support for HTTP Basic authentication in clients: the SRU/W
2114 codec encodes the username/password elements of the PDU structure
2115 appropriately, and these may be set using the "user" and "password"
2116 options in ZOOM-C applications (the same options that are used for
2117 Z39.50 authentication).
2119 --- 3.0.8 2007/06/25
2121 Fixed bug #1208: SSL appears to be broken in ZOOM.
2123 Fixed bug #1206: Libxml2 include path weirdness.
2125 Added oid_name_to_dotstring.
2127 Allow elementSetName to be specified for ZOOM C record update.
2129 Allow waitAction to be specified for ZOOM C based for Extended Services.
2131 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2132 syntax OID. Bug introduced in YAZ 3 series.
2134 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2136 --- 3.0.6 2007/06/06
2138 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2139 directory. yaz-client now reads commands from file given by option -f
2140 if specified; then tries to read .yazclientrc in current directory.
2141 Failing that, it reads .yazclientrc from user's home directory.
2143 Added support for correlationInfo Note and ID for Record Update via
2146 Added yaz-client command querycharset which specifies character set for
2147 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2148 (termListAndStartPoint).
2150 Charset ISO5428:1984 is an alias for ISO5428-1984.
2152 Implemented a way to perform scan in a result set using Z39.50. This
2153 is achieved by attaching the result set name in the characterInfo
2154 (type InternationalString) of OtherInformation in the Scan Request PDU.
2155 The result set is identified in the otherinformation by the new OID:
2156 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2157 This allows for scan in result set and faceted search . Zebra did some
2158 of this in the APT term using attribute type 8 and value being result
2159 set. Using the OtherInformation approach for this is cleaner and easier
2160 to work with in proxies and the like. This facility can be used in
2161 yaz-client using new command setscan which takes a result set as first
2162 argument, start position (APT) as second.
2164 Changed decoding of SRU XML packed records to deal with servers that
2165 have recordData with XML data with multiple root nodes. Also make
2166 comparison for recordPacking case insensitive. Again, one server
2167 returns "XML" where others return "xml".
2169 For SRU responses allow Content-Type application/xml as well as text/xml.
2171 --- 3.0.4 2007/05/21
2173 Fixed bug in character set conversion of BER strings. Bug introduced
2176 --- 3.0.2 2007/05/08
2178 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2180 For OID class, use oid_class consistently.
2182 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2185 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2186 character set for bibliographic information interchange". By Giannis Kosmas.
2188 Added documentation on new OID API.
2190 --- 3.0.0 2007/05/02
2192 Changes to generic frontend server interface: added new member
2193 'query_charset' for bend_initrequest structure. A backend init handler
2194 should set this member to its native character set for query terms.
2195 When defined, the frontend server logic will announce this character set
2196 to a client if the negotiationModel bit is set by the client. All server
2197 implementors are encouraged to specify this. If a backend server does not
2198 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2200 Added CCL utility to remove terms (stop words) from resulting RPN
2201 tree. This is handled by functions with prefix ccl_stop_words_ .
2203 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2204 terms in RPN queries.
2206 Clean-up the CCL API. Moved some internal structures from ccl.h to
2207 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2208 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2209 This is replaced by ccl_parser_find_str which takes a string instead.
2211 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2212 libyaz.la is the core of YAZ except the generic frontend server and
2213 does not depend on POSIX threads anymore. libyaz_server.la is the
2214 generic frontend server facilities and uses POSIX thread functionality
2215 if available. The libyaz.la no longer depends on POSIX threads because
2216 the number of global structures is limited. NMEM no longer re-uses blocks
2217 between threads ; it simply free's memory immediately but allocates in
2218 "large" chunks as usual. We don't expect any performance penalties
2219 because of this. The yaz_log system is still using a global log_level so
2220 caution must be taken when modifying it with yaz_log_init_.. +
2221 yaz_log_mask_str. This, however, should not cause any trouble because
2222 these functions are called during initialization of application code
2223 anyway. `yaz-config --libs server` returns libs for server applications;
2224 `yaz-config --libs` returns libs for non-server applications.
2226 New OID database - with public definitions in oid_db.h. Removed old OID
2227 database including the head oid.h and definitions such as enum oid_value
2228 and struct oident. The new OID database uses the same string names as
2229 before but the 'protocol' is gone. There are now only two representations
2230 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2231 converts from string to OID; functions with prefix yaz_oid_to_string
2232 converts the other way.
2234 Change to emit_term() in CQL-to-PQF query translation: when a term has
2235 the /regexp relation modifier, do not process it for leading and
2236 trailing "^" and "*", which have quite different meanings in regular
2239 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2240 write handlers no longer carries a 'last' parameter. This will make
2241 yaz_iconv flush "less" characters. A flush is performed by call to
2242 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2244 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2245 removed, because function yaz_query_to_wrbuf does the same.
2247 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2248 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2250 Deprecated MARC utility functions removed.
2252 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2255 Branch split: YAZ_2_1_55_branch
2257 --- 2.1.54 2007/03/16
2259 Fix to ZOOM-C so that transparent reconnection is properly handled on
2260 connections that are in asynchronous mode.
2262 Fixed compilation on OpenBSD 4.0.
2264 Large strings in GRS-1 records are now properly displayed in yaz-client.
2266 Added character conversion support for "advancegreek"; based on patch from
2269 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2270 sequence is met. Before the error was not set so it would be unknown.
2272 Adjust yaz-marcdump MARC reader so that it skips until record separator
2275 --- 2.1.52 2007/03/07
2277 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2278 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2279 fd_set structure used as a bitmask for the FDs to be selected on.
2281 Using ACX_PTHREAD macro to check for POSIX threads.
2283 Fixed have-vsnprintf check.
2285 --- 2.1.50 2007/02/23
2287 Fixes for configure on BSD. Bug #900.
2289 Added snprintf/vsnprintf wrappers for systems that don't have
2290 limits (heavens forbid).
2292 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2293 created before all previous tasks were completed and removed from the
2294 task queue, the new task could be removed by a mistake.
2296 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2298 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2300 Fixed bug #832: Problem with MARC/charset in yaz-client.
2302 Fixed bug #668: save command line history for yaz-client.
2304 Fixed bug #830: pkg-config support.
2306 --- 2.1.48 2007/01/23
2308 Extended ZOOM result set options with two options that may be read by
2309 a client: resultSetStatus and presentStatus with values as specified for
2311 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2313 Fixed bug #827: Using SSL fails on Debian etch.
2315 Fixed bug #826: Weird looking chars for set of MARC records.
2317 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2318 that is treated as an ItemOrder with itemRequest being an XML document
2319 external. The value of "doc" is the content.
2321 Extended the GFS search facility. New member of bend_search_rr
2322 'estimated_hit_count' signals that hits is known to be an estmate
2323 (higher or lower than real hit count). New member 'partial_resultset'
2324 signals that the search was partial (hit count is lower or equal than
2325 real hit count). For Z39.50, the information is stored in resultSetStatus
2326 member of SearchResponse APDU. For SRU, the information is signalled
2327 via SRU diagnostic 59: "Result set created with valid partial results
2330 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2332 --- 2.1.46 2007/01/13
2334 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2336 Added ZOOM_connection_peek_event.
2338 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2339 the following new functions:
2340 ZOOM_event_nonblock, ZOOM_connection_process,
2341 ZOOM_connection_get_{socket,mask,timeout},
2342 ZOOM_connection_fire_event_{timeout,socket}.
2343 The existing blocking event handler, ZOOM_event, is a wrapper for the
2344 + blocking ZOOM_event_sys_{poll,select}.
2346 Implemented function ccl_xml_config which parses XML version of CCL
2347 configuration (bug #798).
2349 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2351 Added timings utility (yaz/timing.h)
2353 --- 2.1.44 2007/01/03
2355 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2358 Fixed bug #779: Rotation of apdu.log fails.
2360 Fixed for character set conversions:
2361 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2362 Honor G1 set in MARC-8 decoding.
2364 --- 2.1.42 2006/12/17
2366 Fixed bug #775: char conversion does not handle Alternative UTF-8
2369 Implemented function yaz_marc_read_line which parses MARC line format
2370 records. There is a wealth of formats out there. So far, this function
2371 reads line records produced by yaz_marc_write_line.
2373 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2374 more generic and easier to remember(!) options: -i format and -o format
2375 which specifies input format and output format respectively - where
2376 format is one of "marc", "marcxml", "line", "marcxchange".
2378 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2379 does not print anything except warnings for records.
2381 For yaz-marcdump, added support for MARC split into files (-s) with a given
2384 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2385 spec, at http://www.loc.gov/standards/sru/record-update/
2386 This has changed the binary layout of the following structs:
2387 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2388 bend_update_rr . Patch by Ko van der Sloot.
2390 Added GFS utility function bend_assoc_is_alive which returns 1 if
2391 association is still alive (client is connected); 0 otherwise (client
2392 closed connection). This allows busy servers to stop working for
2395 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2396 been a separate piece of software. This version of ziffy has been modified
2397 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2399 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2401 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2402 Client code may now interrogate options such as "init_opt_sort" to
2403 find out whether the server claims to support various options.
2405 --- 2.1.40 2006/11/27
2407 Added utilities yaz_{set,get}_esn to set/get element set name from
2410 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2411 of YAZ and has been so since YAZ 2.1.10.
2413 Implemented ZOOM_record_error which returns error information for
2414 record (surrogate diagnostic).
2416 --- 2.1.38 2006/10/31
2418 Updates for SRU Update by Ko van der Sloot:
2419 1. Changed name from "operation" to "action"
2420 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2421 versions in the code, marked as 'backward compatible'.
2422 3. Added diagnostics for SRU Update.
2424 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2426 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2428 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2430 For GFS, fixed problem with SRU diagnostic 'First record position out of
2431 range' being issued for 0 hits.
2433 zoomtst10 part of Windows Build.
2435 --- 2.1.36 2006/10/13
2437 Implemented yaz_filepath_comp which splits a path into file path
2438 components (required by Zebra 2.0.3+).
2440 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2441 BSD inspired license until now so this should not have any real impact on
2442 anybody. See http://www.opensource.org/licenses/bsd-license.php
2444 Fixed bug #687: Missing log lines.
2446 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2449 Fixed bug #689: SRU diagnostics to be added.
2451 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2452 whether a connection is idle (no more work do do).
2454 --- 2.1.34 2006/10/04
2456 Change type of optval from long to int for invocation of setsockopt with
2457 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2459 Added support for specifying the max log file size for the Generic
2460 Frontend Server. The size is given with option -r.
2462 --- 2.1.32 2006/09/21
2464 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2466 --- 2.1.30 2006/09/17
2468 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2471 Fixed bug in Generic Frontend Server that could cause a server to stop
2472 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2474 For the generic frontend server, the maximum record size is used as maximum
2475 size of incoming packages (SRU + Z39.50). The value until was previously
2476 only used in Z39.50 Init negotiation and, later, in a session controlled
2477 sizes of records returned. This is controlled using -k option. It can be
2478 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2480 --- 2.1.28 2006/09/04
2482 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2485 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2487 New option for yaz-marcdump -lpos=value which allows setting a portion
2488 of MARC header to a certain value.
2490 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2492 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2493 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2495 --- 2.1.26 2006/08/15
2497 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2500 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2502 --- 2.1.24 2006/08/08
2504 Fixed MARC ISO2709 encoding routines to deal with character set
2507 Minor changes to GFS logging. Database included in search request log
2510 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2511 cached/multiple records.
2513 Shared libraries are built by default on Unix+configure.
2515 Changed cql2pqf transformation to use a different evaluation order. The
2516 new order is: always, relation, structure, position, truncation, index
2517 and relationModifier. Old order was: always, relation, relationModifier,
2518 structure, index, position, truncation. Note that the the latter ones
2519 override former ones for identical attributes.. The new scheme means that
2520 it is possible to override any existing attribute with a relationModifier.
2521 And also that it is possible to override everything for the index rule
2522 (except the ones listed in relationModifier). No order is perfect but this
2523 one, we believe, covers more real cases.. The "always" should have been
2524 called "default", since the attributes there can be overridden with all
2527 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2528 compilation phase, but also for yaz-config --cflags output. This allows
2529 us to have public headers with Libxml2 stuff in them . It should also,
2530 eventually, make Libxml2 checks redundant in packages using YAZ, such
2533 --- 2.1.22 2006/06/15
2535 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2536 stored in uri, message and details.. Previously diagnostics were stored
2537 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2538 compatibility.. but he's probably the only one affected, so.
2540 Added support for CCL, compiled on the client side, in ZOOM-C. This
2541 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2542 input; the resulting query objects can be used for for searching with
2543 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2545 YAZ' configure searches for OpenSSL by default.
2547 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2548 SL_CTX_use_certificate_file. See
2549 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2550 for more info. Thanks to Ko van der Sloot.
2552 --- 2.1.20 2006/06/02
2554 Bug #600: SRU GET, POST support for yaz-client. Introduced
2555 command 'sru' which selects method SOAP/GET/POST.
2557 Allow missingValueAction to be specified for the sortspec string -
2558 function yaz_sort_spec. By default, the missing value action is null.
2559 Use ! to specify "abort". Use = followed by stringvalue to specify default
2562 Ensured that Present-handler (if defined) is called in GFS before any call to
2563 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2564 searchRetrieve requests.
2566 Documentation for YAZ is now based on the Docbook XML/XSLT using
2567 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2568 is no longer depending on jade/openjade or docbook-to-man scripts.
2569 PDF is no longer part of the distribution - but can optionally be
2570 made using DSSSL/jadetex or FOP.
2572 Added retrieval handling support in Generic Frontend Server to support
2573 conversion between MARC/XML as well as XSLTtransforms. See
2574 etc/yazgfs.xml for an example.
2576 Added Authentication support to Generic Frontend Server in SRU
2577 mode. Authentication using HTTP Basic is supported, as is the use
2578 of 'x-username' and 'x-password' parameters in the request itself.
2580 Added support for a new character set MARC8s identical to MARC8 except
2581 that it converts combined characters to single Unicode characters in the
2582 Latin-1 range (when possible).
2584 --- 2.1.18 2006/04/24
2586 ASN.1 compiler 0.4: generates brief Doxygen file header for
2587 generated .h/.c files.
2589 Utility yaz_iconv now supports conversion to MARC-8.
2591 New facilities for the MARC module. The reading - and writing of
2592 content are separate methods for the yaz_marc_t handle. The following
2593 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2594 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2595 format). Write functions have prefix yaz_marc_write_.. The existing
2596 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2597 available. Removed support for OAI-MARC and simplexml (not the
2598 simplexml from PHP5).
2600 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2601 to be returned for this connection.
2603 --- 2.1.16 2006/03/31
2605 Allow multiple languages and charsets to be specified with
2606 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2607 negcharset iso-8859-1,utf-8
2609 Translation of proximity nodes from CQL into PQF now works.
2611 Moved to automake 1.8, 1.9.
2613 Added function yaz_log_set_handler which allows a log handler to be
2614 installed. This handler will be called for all log messages. Output
2615 to file is also produced; but that can be disabled by passing NULL
2616 fname to yaz_log_init_file.
2618 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2620 For SRW (including GFS), accept application/soap+xml as content-type
2623 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2624 produces NO stylesheet reference even if a default stylesheet is specified
2627 --- 2.1.14 2006/03/14
2629 Updated Windows package to include yazd.dll + yazd.lib for the
2630 Development component.
2632 If the environment variable YAZ_LOG is set, then it is used as a
2633 string indicating the default level of logging to use if not
2634 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2635 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2636 used as before. So, for example, to omit warnings from YAZ logging,
2637 export YAZ_LOG=-warn
2639 cql_transform() now map structure and other attributes before indexes,
2640 so that index-specific structures and other attributes can override
2641 defaults. So now a combination of mapping specifications such as:
2643 index.dc.date = 1=date-modified 4=5
2644 does the right thing.
2646 cql_transform() now also respects the "always" mapping specification,
2647 which establishes an initial set of attributes to be used for all
2648 terms except where overridden by more specific attributes associated
2649 with the index, relation or modifier.
2651 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2652 which mode to use; one of "post", "get" or "soap" (SRW, default).
2654 Fixes for yaz_iconv routines: changed trie-based character set conversions
2655 to use only non-negative values for bit fields due to Sun's C compiler not
2656 supporting negative values.
2658 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2659 sequences where not read correctly. Fix by Rustam Usmanov.
2661 Updated win/makefile to use options, settings which makes things
2662 compile with VS C 2005.
2664 --- 2.1.12 2006/02/01
2666 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2668 In ZOOM socket code, use select instead of poll on MacOSX.
2670 ZOOM-C now support client-side compilation of CQL into RPN that is
2671 sent to the server, enabling CQL to be used against all Z39.50
2672 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2673 ZOOM_query object, and submit it using ZOOM_connection_search().
2674 The CQL-to-RPN translation uses a configuration file, the name of
2675 which must be specified in the Connection's "cqlfile" option.
2677 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2678 function, which takes as its start-term parameter a ZOOM_query object
2679 (which may have had either CQL or RPN set into it).
2682 --- 2.1.10 2005/11/29
2684 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2685 GFS to support this as well. Backend handler, bend_srw_update, does the
2686 update work. Code contributed by Ko van der Sloot.
2688 Allow retrieval of Search Result-1 information in ZOOM by the use of
2689 options that are attached to a result set. ZOOM documentation updated
2692 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2693 UTF-8 conversion. Patch by Raj Patel.
2695 Added option -m to GFS to control formatting of timestamps in log file.
2697 Added 'exit' as synonym for 'quit' in yaz-client
2699 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2700 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2701 for the new members. Patch by Ko van der Sloot.
2703 Added support for SRU POST. It is supported for content-type
2704 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2706 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2707 Instead make the library libyaz.la multi-threaded. Threading as a whole
2708 can still be disabled by configure option --disable-threads. Previosly,
2709 with older GLIBCs there were problems with MT libs under Apache. This
2710 has now been fixed a long time ago.
2712 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2715 CQL module modified to be case insensitive for relations/indexes/operations.
2717 Fixed bug in CQL transform code: incorrect value relationModifieder
2720 Added 'show all' command for yaz-client which retrieves all results
2723 Added new yaz-client, xmles, which takes a (private) OID and
2724 a document to be sent as an extended service request.
2726 Describe new yaz-client commands wait_response and set_auto_wait.
2728 Increase TCP/IP listener backlog from 3 (which I am guessing was
2729 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2730 that the socket will queue as many incoming connections as it's able
2731 to handle ongoing connections. In other words, it will never now
2732 refuse a connection that it would be able to handle merely because
2733 it's not got around to accepting() enough of the pending connections
2734 yet. This is the behaviour anyway under Linux, where the listen()
2735 argument is ignored; but not under BSD and on systems such as
2736 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2737 YAZ-based servers should now be uniform across operating systems in
2740 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2741 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2742 This allows yaz-marcdump to read large MARC batches (>2 GB).
2744 Modified all YAZ source files - except the source which is auto-generated
2745 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2748 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2749 corresponding to the existing *_setl() function. These allow option
2750 values containing arbitrary valuues.
2752 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2753 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2754 except that it returns an indicator of whether or not the sort
2755 criterion was accepted (0 for OK, -1 for invalid).
2757 --- 2.1.8 2005/06/07
2759 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2760 MARC output rather than returning "new" buffer.
2762 yaz-client warns about unknown init options.
2764 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2766 --- 2.1.6 2005/05/24
2768 Added support for SRW sort in Generic Frontend Server. Patch
2769 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2770 sortKeys - or NULL if none is provided.
2772 Fixed bug #307: It was impossible to specify indefinite/no timeout
2773 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2776 Added support for multiple languages and charsets to be specified in
2777 ZOOM. Each charset/language is separated by a blank. If negotiation is
2778 in effect in init-response, Option
2779 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2780 Code based on patch by Vasiliy Osadchuk.
2782 Fixed bug #306: infinite recursion that occurred when calling
2783 yaz_log_level_init as the first call (before other log level or
2786 Fixed bug in scan handling in front end server: if preferred-Position-In-
2787 Response was non-present, a NULL pointer referece was performed.
2789 --- 2.1.4 2005/04/26
2791 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2792 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2793 now defined for all those error codes. So instead of putting 109 in
2794 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2795 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2797 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2800 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2802 Program yaz-client now exits and produces an error message if multiple
2803 Z39.50 servers are specified on the command line (none or one allowed
2806 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2809 --- 2.1.2 2005/03/16
2811 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2813 Fixed bug #272: Preserve spacing for CCL terms.
2815 --- 2.1.0 2005/03/14
2817 Added support for virtual hosts and multiple backend servers for
2818 the YAZ frontend server. The configution is XML based and
2819 support specificition of CQL to RPN mappings and explain information.
2820 See section "Virtual Hosts" in the YAZ manual.
2822 Extended OPAC display utility. OPAC display utility renders
2823 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2824 to supplement yaz_marc_decode_wrbuf.
2826 Fixed a bug in MARC decoder that could caused it to crash for some
2827 invalid MARC records. More diagnostics and warnings where added in
2828 XML output (warnings, etc are stored in comments).
2830 --- 2.0.34 2005/02/08
2832 Fixes for UNIX domain sockets. Bug #261.
2834 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2836 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2837 Added yaz_marc_subfield_str which defines subfield lead string which is
2838 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2839 yaz_marc_endline_str which defines end of fields string used in
2840 YAZ_MARC_LINE format. Default string is newline.
2842 Experimental support for MarcXChange. This format can be produced
2843 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2844 http://www.bs.dk/standards/MarcXchange.xsd
2846 Added yaz-client commands scansize that sets maximum number of
2847 entries to be returned by scan.
2849 --- 2.0.32 2005/01/11
2851 Added support for SRW scan in yaz-client and Generic Frontend Server.
2853 * Added whereInList member to SRW Scan Term.
2855 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2857 Fixed NMEM system to return aligned blocks on the smallest boundaries
2858 that are suitably aligned for all possible types on the particular
2859 architecture YAZ is being built for.
2861 --- 2.0.30 2005/01/04
2863 Fixed numerious warnings that was issued with newer versions of GCC.
2865 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2866 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2869 Make YAZ Generic Frontend Server slightly faster.
2871 Enhance (and reduce) logging for Generic Frontend Server.
2873 Revert YAZ log system so that it flushes every write operation
2874 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2876 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2877 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2878 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2879 will effectively disable old definitions.
2881 --- 2.0.28 2004/11/09
2883 Added yaz_log_time_format which specifies log format using
2886 Added yaz_log_module_level which returns mask for a module. Value
2887 is non-zero mask a if module is enabled; zero if disabled.
2889 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2890 in include/yaz/cql.h.
2892 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2894 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2896 Fixed bug #172: RPM builds does not enable SSL.
2898 Doxyfile.in part of dist. Doxyfile generated by configure.
2900 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2901 are given and the corresponding component does not exist.
2903 Extend CCL documentation in YAZ reference. Describe r=r.
2905 --- 2.0.26 2004/10/01
2907 Fixed MARC->MARCXML conversion to properly deal with
2908 fields, subfields, indicators having non-ASCII characters.
2910 Fixed MARC->MARCXML conversion so that ASCII control characters
2911 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2914 Added YAZ GFS support for conversion from Z39.50 surrogate
2915 diagnostics to SRW surrogate diagnostics.
2917 Bug fix: YAZ GFS did not return schema in explainResponse.
2919 --- 2.0.25 2004/09/30
2921 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2922 now converts recordSchema to elementSetName as well as schema URI.
2924 Fixed bug in COMSTACK that prevented HTTP request packages from being
2927 --- 2.0.24 2004/09/29
2929 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2930 does not require white-space before and after the dash in a range, e.g.
2931 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2934 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2935 due to new GCC removing "redundant" code.
2937 Added yaz-client commands scanpos and scanstep that sets preferred
2938 position and step-size for scan.
2940 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2942 Added CCL utility ccl_qual_buf which parses one or more CCL
2943 spec lines in a buffer.
2945 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2946 of name and value - ignoring empty lines and comments.
2948 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2950 Added odr_get_element_path which returns current element path for an
2951 ODR handle. This utility is useful in error handling or user-defined
2954 Added ODR_PRINT utility odr_set_stream which is is a more generic
2955 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2956 to a write function and pointer to close function. The close function - if
2957 non-NULL - will be called during odr_destroy.
2959 Fixed bug in CCL parser where truncation char was not removed from
2960 right side when truncation=both was in effect.
2962 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2965 --- 2.0.23 2004/08/11
2967 Fix buffer overrun in CQL parser when dealing with proximity (%).
2969 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2970 to UTF-8/UCS conversion is now only based on codetables.xml.
2972 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2974 --- 2.0.22 2004/08/06
2976 Add support for more "commit changes" in ZOOM (uses Extended Services).
2978 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2981 Yet another small fix for configure of SSL.
2983 --- 2.0.21 2004/05/14
2985 Fix SSL libs for configure when --with-openssl=DIR is given.
2987 --- 2.0.20 2004/05/10
2989 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2991 SSL comstack now uses yaz.pem certificate file on server side
2992 by default. Certificate filename can be configured by calling
2993 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2995 Fix bug regarding multiple calls to ZOOM_connection_connect.
2997 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2999 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
3000 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
3002 ZOOM now allows inspection of X509 peer certificate for verification.
3003 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
3005 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
3006 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
3007 as "modular" but it simplifies things.
3009 Added cs_get_peer_certificate to that returns peer X509 PEM.
3011 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
3012 NULL if SSL is unavailable.
3014 Documentation about MARC decoding tools.
3016 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
3018 --- 2.0.19 2004/03/30
3020 Rename CHANGELOG to NEWS to follow GNU style packing.
3022 Fix bug with missing initialization of member in init_diagnostics.
3023 This bug affects threaded version of GFS server.
3025 --- 2.0.18 2004/03/20
3027 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
3030 Ensure zlib.dll is packed with Windows install.
3032 --- 2.0.17 2004/03/17
3034 Fix encoding of xsd:string to use text instead of CDATA.
3036 Fix endless loop in CQL parser with unbalanced ".
3038 Use a more compact way to store MARC-8 conversion tables.
3040 --- 2.0.16 2004/03/16 Debian only
3042 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
3045 Update CQL parser to use new CQL 1.1 modifiers for booleans and
3050 --- 2.0.15 2004/03/01
3052 Another fix for decoding of XML packed records.
3054 --- 2.0.14 2004/02/25
3056 Fixes for Chunked encoding. White space not ignored after length spec.
3058 Update NS and use default NS for SRW diagnostic elements.
3060 --- 2.0.13 2004/02/23
3062 Implement ZOOM_resultset_cache_reset which resets record cache.
3064 Implement ZOOM_resultset_sort which sorts a result set.
3066 Implement chunked HTTP transfer.
3068 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
3070 --- 2.0.12 2004/02/16
3072 Added member 'schema' to bend_explain_rr structure so that backend
3073 can specify explain record identifier. Defaults to Zeerex 2.0.
3075 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
3077 --- 2.0.11 2004/02/16
3079 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
3082 Added init command for yaz-client which sends "extra" init request.
3084 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
3085 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
3087 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
3089 Make ZOOM error code for "invalid query".
3091 Fixed compilation for SSL which wasn't properly enabled for all platforms.
3093 --- 2.0.10 2004/02/05
3095 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
3098 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
3100 Added option -p <file> to make Generic Frontend Server to write PID file.
3102 Added option -D to put Generic Frontend Server in background on its own.
3104 Make ZOOM C recognize option "password". If unset, "pass" is used
3105 (for backwards compatibility).
3107 Fixed a bug in Generic Frontend Server that could make it crash if a
3108 client sets characterSetNegotation bit, but didn't pass negotiation stuff
3111 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
3112 Must be issued before open, in order to be in effect.
3114 --- 2.0.9-6 2004/01/12 Debian/Windows
3116 Make the SRU server more picky WRT unknown params, etc.
3118 Bug fix: ZOOM scan response didn't return displayTerm - when present.
3120 New YAZ client command, options, that sets Z39.50 options.
3122 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3123 options from a string of tokens (one token for each option bit).
3125 Update SRW diagnostic code messages.
3127 --- 2.0.9-5 2004/01/07 Debian/Windows
3129 Handle user defined stylesheet for SRW/SRU.
3131 --- 2.0.9-4 2004/01/06 Debian/Windows
3133 Fix bug in decoding of Content-Length.
3135 --- 2.0.9-3 2004/01/06 Debian/Windows
3137 Fix a bug with decoding of XML packed records.
3139 --- 2.0.9-2 2004/01/05 Debian only
3141 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3143 Fix bug in SRW/SRU diagnostics decoding.
3145 --- 2.0.9 2004/01/05
3147 Fixed bug in Generic Frontend Server which could drop records exceeding
3148 preferred message size. Reported and fixed by Irina Dijour.
3150 Fixed calculation of package size for structured records in Generic
3151 Frontend Server. Reported and fixed by Irina Dijour.
3153 Fixed namespace for SRW/SRU diagnostics.
3155 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3157 --- 2.0.8 2003/12/22
3159 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3160 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3163 CQL changes to reflect recent changes to the specification:
3164 * Documentation talks about context sets instead of index sets.
3165 * Documentation talks about indexes instead of qualifiers.
3166 * The CQL-to-PQF transformer's configuration file now uses
3167 "index.set.name = <attributes>" instead of the old form
3168 "qualifier.set.name = <attributes>". (Both forms are still
3169 understood but the latter is deprecated.)
3170 * CQL terms with no explicit index specified are now interpreted as
3171 cql.serverChoice instead of srw.serverChoice (which of course
3172 behaves exactly the same.)
3174 --- 2.0.7 2003/12/16
3176 MARC conversion can now generate ISO2709 output in another
3177 character set. yaz-marcdump uses this facility if you invoke it
3180 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3181 functions from there can be used from C++.
3183 --- 2.0.6 2003/12/04
3185 Frontend server now transfers memory from decoded packages to stream
3188 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3189 references to show up.
3191 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3192 the ZOOM Abstract API. The older names for the same options are still
3193 also supported for the benefit of old applications.
3195 ZOOM-C supports "implementationId" and "implementationVersion" options
3196 to go along with "implementationName". These allow the user code to
3197 specify identification strings to be sent to servers.
3198 Add OID for the new ExtLite attribute set.
3200 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3201 as requested/supplid by Ere Maijala <ere@atp.fi>
3203 For generic frontend server, reverse the order of
3204 "toolkit-supplied / application-supplied" strings sent as implementationId,
3205 Name and Version. Also, remove the spaces around the slash. This brings
3206 the GFS in line with the behaviour of ZOOM-C on the client side.
3208 Add function ZOOM_scanset_display_term.
3210 yaz-client shows scan displayTerm if present.
3212 Utility yaz-iconv is now installed by default along with the man page
3215 Extend configure check for OpenSSL to use pkg-config where available (such
3218 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3219 server to specify uid/gid/mask for socket using the format
3220 unix:[user=uid,][group=gid,][umask=mask,]file=path
3221 If file= is omitted the existing format is assumed, e.g.
3223 in which case the mask is 0666 (rw for everybody).
3225 Major restructure of YAZ source. All source in libyaz is in src directory.
3226 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3227 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3229 Added man page for utility yaz-marcdump (used to be called marcdump).
3230 yaz-marcdump is installed by 'make install'.
3232 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3233 of incoming package failed.
3235 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3237 Change prototype of odr_perror: add const to message string.
3239 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3241 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3242 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3243 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3244 DNS lookup. There should not be any compatibility problems with this
3245 assuming that blocking=1 or 0 is used.
3247 Fix bad reference in UNIX comstack in function cs_addrstr.
3249 Fix for compilation on AIX.
3251 The generic front-end server (server/seshigh.c) now supports returning
3252 Init diagnostics to the client in User-information-field, in
3253 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3256 --- 2.0.4 2003/09/04
3258 Allow any CQL relation (not just all,any,exact,scr).
3260 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3261 that features the same UI.
3263 Implemented command update0 in YAZ client which is equivalent to
3264 update but uses old of Ext Update ASN.1.
3266 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3267 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3268 Previously no OID was used for this info.
3270 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3271 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3272 returns 'malformed search term' otherwise.
3274 SortResponse member resultCount now set to NULL in sort handler of
3277 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3280 Add three new utility functions for translating OIDs between various
3281 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3282 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3283 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3284 char *oid_to_dotstring(const int *oid, char *oidbuf);
3285 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3287 Reverted modifications for ES Update definition for z_IU0Update
3288 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3289 is back to YAZ 2.0.2.
3291 String value attributes for CCL parser.
3293 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3294 which their FirstSearch server returns in Init responses, sometimes
3295 carrying useful diagnostic information when Init fails. This has the
3296 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3297 "z39.50/oclcui.asn", where its definition is somewhat different from
3298 what OCLC document on their web-site, as required to interoperate with
3301 Support for anonymous authentication in yaz-client. Use the command
3304 * Fix the OID of the Index Data-local "admin" Extended Service from
3305 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3306 the 1000, which indicates a locally-defined OID, was a mistake.
3308 --- 2.0.3 2003/06/20
3310 Fix CCL directive @case handling so that it affects string match for
3311 both CCL keywords and qualifiers.
3313 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3314 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3315 Decoder has been updated with ASN.1 changes as listed in
3316 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3317 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3318 z_IUUpdate, remains unchanged.
3320 ZOOM_record_get may now return a record in a specific character set.
3321 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3322 "from" is the character set of record as returned by target. "to" is
3323 the character set to be returned. If omitted, "to" is UTF-8.
3325 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3327 New ODR utility, odr_getelement, which returns name of element for
3328 which encoding/decoding failed.
3330 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3331 in cases where a required element was omitted.
3333 Bug fix: some MARC8 sequences were not converted.
3335 New ZOOM option "step" which specifies number of records to be
3336 retrieved in one chunk. Used in conjunction with "start" and "count".
3338 SRW support for yaz-client. Use scheme http: to use it, e.g.
3341 yaz-client no longer does (un)intelligent character set conversions
3342 by default. Can be enabled with charset and marc_charset commands.
3344 xmalloc trace fix for 64-bit systems such as DEC alpha.
3346 Solaris 2.6 compile fix.
3348 New function, cql_strerror() translates SRW error codes, as returned
3349 by cql_transform_error(), into human-readable English strings. Used
3350 in yaz-client diagnostics when appropriate.
3352 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3353 converts it into a type-1 query which is sent to the server. This
3354 makes CQL available for use with all Z-servers, as opposed to the tiny
3355 minority that can handle CQL queries themselves.
3357 --- 2.0.2 2003/04/28
3359 New Debian package layout similar to the Redhat Package layout.
3361 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3362 and search result respectively.
3364 --- 2.0.1 2003/04/25
3366 Redhat package is now several packages: libyaz (runtime libraries),
3367 libyaz-devel (development and documentation, and yaz (utility programs).
3368 Package spec file by Morten Bogeskov.
3370 New member 'schema' in struct bend_fetch_rr which the name of requested
3371 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3372 handler MAY set this to reflect the schema of the returned record.
3374 New member 'display_term' in struct scan_entry. GFS now sets member entries
3375 and allocates scan entries to be filled by user scan handler. In previous
3376 version, entries member was allocated by the scan handler. That still works,
3377 but the GFS will ignore member display_term - assuming it was NOT set by
3378 the handler. The fact that the GFS now allocates the entries both allows
3379 for new members and makes a scan handler easier to write.
3381 Fix CQL lex buffer overflow.
3383 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3384 SRU default recordPacking is string.
3386 SRU protocol support for frontend server.
3388 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3390 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3392 Added scan for the ZOOM shell (zoomsh).
3396 * String Identifers for Schemas (Amendment 5).
3397 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3398 Old definition for schema
3399 Odr_oid *schema; /* OPT */
3404 Z_InternationalString *uri;
3405 #define Z_Schema_oid 1
3406 #define Z_Schema_uri 2
3409 * resultCount parameter to Sort Response (Amendment 1).
3410 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3412 Support for SRW 1.0 over HTTP. This is an optional feature and
3413 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3416 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3417 on the same port. SRW SearchRetrieveRequests are mapped
3418 to bend_init,bend_search,bend_fetch,bend_close.
3420 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3422 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3423 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3425 ZOOM connections are SRW based if schem http is used for hostname
3426 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3427 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3429 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3430 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3431 distance=n, order=true/false, relation=le, prox unit=word. If
3432 n is omitted, distance 1 is used.
3434 Fixed problem with C compiler include path in wrong order.
3436 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3437 on Solaris. Patch from Ko van der Sloot.
3439 New MARC decode API. All new functions operate on a yaz_marc_t
3440 handle. The most important new functions are: yaz_marc_create,
3441 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3442 decode and destroy respectively. Decoder can produce formats
3443 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3444 include/yaz/marcdisp.h.
3446 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3447 to UTF-8, UCS-32, wchar_t or Latin-1.
3449 * Prototypes for yaz_iconv_-functions moved to separate header
3450 include/yaz/yaz-iconv.h.
3452 Make a few private functions 'static' in unix.c. This prevents
3453 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3455 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3456 are set when Init Response is received.
3458 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3459 but returns diagnostic set as well.
3461 New function yaz_strerror which is a portable wrapper for
3462 strerror/strerror_r/GetLastMessage.
3464 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3465 is returned for MARC. If type is "oai", then OAI MARC is returned.
3467 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3470 --- 1.9.2 2002/11/26
3472 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3474 Fix bad race conditions on SIGTERM and terminate gracefully in
3477 Move retrieval (data1) module to Zebra since nobody seems to be
3480 Add GRS-1 render for ZOOM using same format as yaz-client.
3482 --- 1.9.1 2002/10/05
3484 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3486 Fix broken ESpec handling in data1 module.
3488 SGML reader parses comments and makes them part of the data1 tree.
3490 Added several type casts so that YAZ compiles as C++ code.
3492 ZOOM didn't handle PDU encoding failures properly.
3494 Added more Bib-1 diagnostics (approved extensions).
3496 GNU configure: better check for iconv.
3498 More portable use of accept, getpeername. Check for socklen_t. Use
3499 int/size_t if socklen_t is not defined.
3503 PQF parser rejects bad queries - including those with extra
3504 characters in them. PQF parser used to silently ignore that.
3505 Cleaner API for PQF added, which allows you to get detailed
3506 error information for bad queries (see yaz/pquery.h).
3508 Fixed bug in ZOOM_record_get for type "database".
3510 Implemented mini iconv library supporting conversions between
3511 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3513 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3515 --- 1.8.9 2002/08/20
3517 Fixed ZOOM C record cache so that preferredRecordSyntax and
3518 elementSetName is used to check for already fetched records.
3520 --- 1.8.8 2002/08/02
3522 Added three members in bend_initrequest structure to facilitate
3523 character set negotiation.
3525 Fixed a bug in frontend server that could cause indefinite
3526 loops under rare conditions.
3528 Revised character set utilities (charneg.h) so that encoding
3529 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3531 For PQF, directive @term <type> sets term type for Scan/Search.
3532 Here <type> is general, string, numeric, null. The term type
3533 is inherited - just like @attr.
3535 New call odr_set_charset that sets character set conversion for
3536 international-strings on a ODR stream. Prototype is:
3537 int odr_set_charset(ODR o, const char *to, const char *from);
3538 The InternationalString is still represented as C string in YAZ
3539 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3540 won't). On the protocol level, you can use any encoding.
3542 Support for UNIX sockets in ZOOM.
3544 Solaris recv sometimes returns errno == ENOENT. It is treated as
3545 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3547 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3548 both client and server. Code by Morten Bogeskov.
3550 --- 1.8.7 2002/05/22
3552 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3553 that they can be used directly from Visual Basic. You must recompile
3554 your windows APP if you're using ZOOM.
3556 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3557 Commands "lang" and "charset" sets language and character set respectively.
3558 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3559 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3561 Attributes from multiple CCL fields may be OR'ed rather than merged
3562 using directive "@field or". Fields are still merged by default -
3563 equivalent to "@field merge".
3565 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3568 Fixed bug in zget for parameter ExtendedServicesResponse.
3572 --- 1.8.6 2002/03/25
3574 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3576 Client displays USR.1:SearchResult-1 (hits per term).
3578 Additional Search Info for search in Generic Frontend Server.
3580 Fixed CCL parsing of "field=s".
3582 WIN32 installer - using the excellent NSIS software from nullsoft.
3584 Fixed CCL parsing of "field = - <number>".
3586 Added function yaz_marc_decode that decodes MARC for line mode
3587 display or XML (similar to that used by JZKit).
3589 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3590 Z39.50. But ISO/ILL was, however.
3592 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3593 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3595 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3596 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3598 --- 1.8.5 2002/02/03
3600 New YAZ client features: Command completion and new commands:
3601 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3602 Code provided by Jacob Poulsen.
3604 New call oid_trav, that visits all registered OIDs via callback.
3606 Function ZOOM_record_get now returns const char pointer rather than
3607 void pointer. It saves a lot of type casts.
3609 For YAZ client, command "auth" now allows you to set authentication
3610 in IdPass style. It is enabled when three tokens are given - order
3611 is user, group and password.
3613 Fix memory leaks in MARC record handling for ZOOM.
3615 New option for YAZ client, -k <kilobytes> that sets
3616 maximum record size. Similar to -k option for generic frontend
3617 server and yaz-ztest.
3619 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3621 Prefix query parser reports "fail" when bad attribute set is given.
3623 Fix in MARC decoder. Proximity logging. Fix for attribute set
3624 in scan handler for server. Patches by Shigeru Ishida.
3626 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3629 Configure option --with-openssl=<dir> now works when a directory is
3630 specified. Patch provided by Morten Bogeskov.
3632 New option for YAZ client, -u <auth>, that sets authentication.
3634 ZOOM fix: error information was sometimes "missing", since error
3635 was cleared/reset too when it shouldn't.
3637 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3639 --- 1.8.4 2002/01/04
3641 Scan for ZOOM API. New object ZOOM_scanset. New functions
3642 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3643 ZOOM_scanset_destroy.
3645 New ZOOM function, ZOOM_connection_last_event, that returns type
3646 of last event (such as "receive data", "send data", "apdu received",
3649 New ZOOM option, schema, that specifies schema for retrieval.
3651 New CCL feature. Qualifiers can be aliases for one or more
3652 other qualifiers (if more than one is given, OR is used).
3654 ZOOM uses named result sets if target supports it.
3656 Two new YAZ client commands: . (dot, which sources a script of YAZ
3657 client commands), and ! (to execute shell command.). Implemented
3660 Working on Debian packages.
3662 --- 1.8.3 2001/11/19
3664 YAZ client enables named result sets only if target supports it.
3666 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3668 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3669 with key="host" to get same result.
3671 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3672 Function Z3950_resultset_record(s) returns references to records
3673 "owned" by resultset. To become owner use Z3950_record_clone.
3675 Function z_ext_record handles Extended Services. Thanks to
3678 --- 1.8.2 2001/11/12
3680 CCL Parser fix: ignore token comma when dealing with and-lists.
3682 Documentation updates for COMSTACK.
3684 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3685 Changed prototype Z3950_records. For some functions, int parameters
3686 were changed to size_t.
3688 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3691 New MARC decode/display function, marc_display_exl, which properly rejects
3692 non-ISO2709 records. YAZ client uses it.
3694 --- 1.8.1 2001/10/29
3696 Fix bug: local attribute set wasn't set correctly in PQF strings.
3700 * Old Z39.50 codecs no longer supported.
3702 Added ZOOM C binding. See http://zoom.z3950.org/
3704 Renamed states for COMSTACKs to avoid confusion with events.
3706 Implemented cs_look and proper cs_rcvconnect.
3708 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3710 Configure detects POSIX threads on OpenBSD.
3712 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3713 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3715 When error is returned from present handler, non-surrogate diagnostic
3716 is returned in present response (and fetch handler is no longer called).
3718 * Minor adjustments to pquery parser (PQF). Token characters may be
3719 escaped by using backslash (C-style).
3721 PQF parser allows string attribute values to be specified. For @attr,
3722 non-numeric characters after the equal-sign are treated as strings
3723 (e.g. @attr 9=title).
3725 CCL trunction character may be defined (@truncation in file)
3727 * function zget_ExtendedServicesRequest sets waitAction to
3728 waitIfPossible (was wait).
3730 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3733 CCL operator names may be set in field definition files (CCL_bibset).
3734 See ccl/bib1 for an example.
3736 Fixes in ASN.1 compiler for C++ compatibility.
3738 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3739 and "op_or" to avoid conflict with C++.
3741 Fixed problem with GNU readline detection on Redhat 7.0.
3743 Added step-size for Scan backend handler.
3745 Fixed bug that made the frontend server crash when no attribute
3746 set was specified for scan.
3748 Front-end server automatically switches to original working directory
3749 when installed as an NT service. Previously -w had to be specified to
3752 Added extended attributes for retrieval module (data1), so that data1
3753 records carry d1_readXML/SGML attributes. d1_read also supports
3754 null-data rules ( <tag/>)
3756 On UNIX when POSIX threads are available, a separate library libyazthread
3757 is created. Programmers should link with that library and the yaz library
3758 when using threads. The reason for the split was that some applications
3759 on Linux, such as Apache, doesn't work well when using shared objects that
3762 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3763 (or any frontend server) in SSL mode by specifying ssl: followed by
3764 address. Only tested on UNIX.
3766 Added feature for CCL module. Virtual structure s=al or s=ol generates
3767 and-list and or-list respectively instead of phrase search.
3771 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3772 log_mask_str. This was done to avoid name conflicts with other libraries
3773 (such as other PHP extensions).
3775 Added raw OID member for preferred record syntax (request_format_raw)
3776 and returned record syntax (output_format_raw) for backend fetch method.
3778 Config file yaz-config now accepts options so that it returns specific
3779 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3781 Shared library support for UNIX using GNU libtool.
3783 * Modified backend interface. Request/Response struct's replaced by
3784 one read/write C struct. For example bend_fetchrequest and
3785 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3786 Every handler - even search has to be registered in bend_init
3787 handler. This means that the YAZ library no longer refers to
3788 external functions and it makes it possible to make the whole
3789 thing a single DLL/SO.
3791 Added Segment handler for backend server.
3793 Added Zmbol/Zebra administrative functions to YAZ client.
3795 Threaded frontend server on UNIX (when POSIX Threads are available).
3796 Starting the server with option -T enables multi-threading.
3800 Added configure option --enable-comp/disable-comp to control use
3801 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3802 located in sub directory asn.
3804 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3805 in ${exec_prefix}/bin along with the other programs yaz-client and
3808 GNU automake used to maintain makefiles.
3810 Added several OID's.
3812 Changed retrieval module so that we can load records with no abstract
3813 syntax defined. Tagpaths in these records are fully composed of string
3816 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3820 On UNIX, the generated makefile now supports a proper 'make install'.
3821 The prefix can be set via GNU configure to set the install location
3822 (default is /usr/local).
3824 * YAZ programs client and ztest were renamed to yaz-client and
3825 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3826 locations, such as /usr/bin,/usr/local/bin,etc.
3828 * YAZ Header files were moved from include to include/yaz. YAZ Header
3829 files are referred to as include <yaz/log.h> rather than <log.h>.
3830 The YAZ include path (-I ..) is therefore the same as before. Programmers
3831 should update their #include statements or use -Ipath/include/yaz
3832 instead. The main motivation for doing this change is that YAZ header files
3833 can be installed in "standard" locations /usr/include,/usr/local/include
3834 without introducing conflicts, since ALL YAZ header files are stored
3835 in subdirectory yaz (under /usr/include for example).
3837 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3838 rather than project/workspace files. We switched because project files
3839 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3842 Changed name of logging function, logf, to yaz_log, to prevent name
3843 clash with some math-log functions. The YAZ header log.h defines logf
3844 to yaz_log (#define) so there should be no incompatibilities by this
3847 Added bend_start/bend_stop handlers for server. These handler are
3848 called on start/stop of server. For windows they are called whenever
3849 a service is started/stopped.
3851 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3852 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3853 in util/yc.tcl. The auto-generated C code structures are, in a few
3854 cases, incompatible with the old decoders. There are differences in the
3855 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3856 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3857 The preprocessor variable ASN_COMPILED is defined when the compiled
3858 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3859 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3860 wish to use the old encoders/decoders you can specify --disable-yc
3863 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3864 version so that it supports both new - and old version of DB Update
3866 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3867 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3868 change. The name parameter can be set to 0 in which no name is specified
3869 for the construction. The macros odr_implicit and odr_explicit sets name
3870 parameter to zero for the construction involved. New macros
3871 odr_implicit_tag and odr_explicit_tag are similar to the others,
3872 except that a name parameter is added. For programmers' that don't use
3873 ODR they probably only need to change the call to z_APDU and z_External.
3875 Added access control facility by interfacing the TCP wrapper library.
3876 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3877 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3878 name of the daemon and enables the access control as specified in
3879 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3881 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3882 den Dool <H.M.vdnDool@kub.nl>.
3884 Added reference ID parameter to most functions in server API - refer
3885 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3887 Changed name of ccl library to libccl.a (was ccl.a).
3889 Fixed bug in decoder for Explain (Category TargetInfo).
3891 Added support for GNU readline in client. Thanks to Jacob Poulsen
3892 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3894 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3895 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3896 IMPLEMENTATION! This change was made to the development version before
3897 the ZIG decided to retract the amendment. If any users MUST be
3898 compatible with the original Update definition, PLEASE CONTACT US, and
3899 we will include a separate definition corresponding to the old Update
3900 ES. Note that because of the change to the ASN.1 of the
3901 TaskPackageRecordStructure we cannot define a single structure that
3902 will support both versions.
3904 * Added const modifier to buffer parameter for some ODR/BER encoding
3905 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3906 completeWAIS, odr_dumpBER.
3908 Fixed bug in client.c which caused a crash when a scanResponse didn't
3909 contain positionOfTerm.
3911 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3912 * will cause an error in a client if a non-YAZ target sends both a
3913 * list of Scan entries and non-surrogate diagnostics.
3915 Retrieval module enhancements. Tag sets may be typed in the reference
3916 to it. From the .abs-file the "tagset" directive takes a third optional
3917 integer type for the tag set referenced. From a .tag-file the "include"
3918 directive takes a third optional type as well. The old "type" directive
3919 in the tag set itself is still recognized but acts as the default type
3922 Backend interface change. Individual Scan terms returned from bend_scan
3923 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3924 in include/backend.h.
3926 Retrieval module enhancements. Multiple tag sets and attribute sets may
3927 be specified in abstract syntax specs. Revised the error/warning for
3928 logging messages reported by the retrieval module when reading the
3931 Object Identifier system (oid_..) changed. The API is backwards
3932 compatible but the oid-routines now allocates new OID's when needed.
3933 Raw OID's may be specified in oid_getvalbyname.
3935 YAZ now uses GNU configure to generate Makefile(s).
3937 * Minor changes in some of the member names of DeleteResultSetRequest and
3938 DeleteResultSetResponse. See include/proto.h.
3940 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3941 and added member 'languages' in TargetInfo (which was missing).
3943 Changed the way attribute sets are handled in the retrieval
3944 module. These are now cached, just like the abstract syntaxes
3947 Changed YAZ so that it links with compiled ASN.1.
3949 Added Explain-schema definitions and mapping routines. The following
3950 Explain categories have been implemented: AttributeDetails,
3951 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3953 Fixed minor bug in Windows version of Server Library.
3955 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3957 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3959 Added EXTERNAL: UNIverse Resource Report (non-standard).
3961 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3962 ENUMERATED and SET OF.
3964 * Added 'const' to some of the char pointer arguments for the
3965 functions, data1_read_node, data1_getelementbytagname,
3966 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3969 Fixed bug in data1_insert_taggeddata - the last_child member of
3970 parent wasn't initialised.
3972 * Changed data1_read_record and data1_read_node so that the supplied
3973 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3974 doesn't refer to any parts of the "SGML"-buffer.
3976 Fixed bug in server library (Windows version of statserv_remove).
3978 * Changed code so that it compiles as C++. The type definition
3979 of Odr_fun which is a member of Odr_arm was changed. The result is,
3980 that an explicit typecast is needed for the fun pointer when
3981 using Odr_arm - as in:
3982 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3984 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3986 Implemented the new structured date and time definition as approved
3987 by the ZIG. Added schemaId element to the specificTag in Espec-1
3988 (also approved at the last ZIG). Thanks to RVDM.
3990 Added some Object identifiers (RVDM).
3992 Changed the Update Extended Service (RVDM).
3994 Added command "refid" to client which specifies referenceId for
3995 the following requests.
3997 Implemented extended service handling for server. See ztest.c
3998 for an example as well as backend.h. New handlers are registerd
3999 in the Init handler.
4001 * Changed interface for sort in server.
4003 Added new members to statserv_options_block. It allows a server
4004 to read options from another source than just the command line. Thanks
4005 to Charles Woodfield.
4007 * Changed definition of Z_Triple in file prt-grs.h - member boolean
4008 renamed to zboolean. Some C++ compilers complained about the name.
4010 Minor changes to gils.abs. Added index 's' (sort) on title
4011 and date/time-last-modified.
4013 --- 1.4pl2 1998/1/30
4015 Fixed bug in server library regarding inetd mode (-i). This bug
4016 was introduced by release 1.4.
4018 --- 1.4pl1 1998/1/29
4020 Added sort facility in client and backend server interface.
4022 Fixed problem with dependencies in Makefile(s).
4024 Fixed bugs for encoders/decoders of extended services and
4027 Implemented sub-tree feature for schemas. Sub-trees are
4028 referenced in *.abs-files. See explain.abs for an example
4029 of the use of this feature.
4031 Modified bib1.att; local attributes for ANY didn't include
4032 ANY itself (only affects use of the retrieval module).
4034 Fixed bug in plain SGML reader in function data1_read_node:
4035 tags with prefix "var" was incorrectly interpreted as variants.
4037 Added feature "sub-schemas" to enable references to - and definitions
4038 of - group of elements.
4040 * Removed member parent from type data1_element (in data1.h).
4042 Implemented function odr_nullval() that returns the value of
4045 * Removed member num_children from data1_node (in data1.h).
4047 Made NT service interface part of the server library. The
4048 function statserv_main uses the NT service when required and
4049 calls the statserv_start / statserv_close routines.
4051 Routine zget_SearchRequest and zget_PresentRequest fills
4052 resultSetName/Id member with "default" instead of "Default".
4054 Fixed memory leak in server. Request queue member wasn't freed.
4056 Fixed nmem_exit so that memory is freed.
4060 Revised the CCL parser utility to be thread safe.
4062 Added function, oid_ent_to_oid, to replace the function
4063 oid_getoidbyent, which is not thread safe.
4065 * Added nmem_init and nmem_exit to initialize and release
4066 NMEM resources. Function nmem_init should be called once in the
4067 initial thread before NMEM/ODR is used. statserv.c and client.c
4068 have been changed accordingly. The change was necessary to make
4069 NMEM thread safe. The NMEM memory pool is shared amongst threads
4070 in a process. Unix-based applications will still work fine without
4073 Added NT Services interface for the the Z39.50 (statserv) Server.
4074 Refer to the ztest.c source on the usage.
4076 Windows 95/NT port using MSVC5.0. Project files are included in the
4079 * Defined new 'global' handle for the retrieval (data1) system. The
4080 new handled, data1_handle, describes the state of the data1 system.
4081 This handle is passed as first argument to virtually all
4082 data1 related routines. The functions data1_create and data1_destroy
4083 creates and destroys a data1 handle respectively.
4085 Added ODR encode stream member to all backend request structures
4086 init, search, scan etc. This stream should be used to allocate all
4087 memory used for the response when thread safe operation is needed.
4089 Changed the comstack utility, cs_addstr, to be thread safe. The
4090 returned hostname string returned by the function is now part the
4093 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
4094 function. The cs_straddr takes a COMSTACK handle as argument, so this
4095 function must be used after cs_create and before bind/connect.
4096 This function is thread safe.
4098 Moved test server to 'ztest' directory - generic server code still
4099 in 'server' directory.
4101 Made prefix query (pquery.c) utility thread safe.
4103 Added new function modifier YAZ_EXPORT to 'export' public DLL
4104 functions when using windows (see include/yconfig.h).
4106 Added definitions to the OID database (util/oid.c) (RVDM).
4108 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
4110 Added call to ccl_rpn_delete in client program.
4112 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
4113 release of RPN structure.
4115 Added support for C++, headers uses extern "C" for public definitions.
4116 With input from RVDM.
4118 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
4119 Thanks to Ronald van der Meer (RVDM).
4121 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4123 Added support for private extensions to the OID database
4124 (oid_setprivateoids()). Thanks to RVDM.
4126 Added optional, physical ANY (key replication)
4128 Fixed null-reference problem in GRS-1 output filter.
4130 Proximity operator added to Prefix Query Format (PQF).
4132 In test client command "base" accepts multiple databases.
4134 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4138 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4140 Smallish bug-fixes in the new encoders/decoders (explain).
4142 Bug fixed in DeleteRequest.
4144 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4146 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4148 Added SOIF syntax (using private OID for now) to retrieval module and client.
4150 Added Update extended service.
4152 Added SearchResult-1 additional info structure.
4154 Added optional CCL (ISO8777) interpreter as separate module. Available
4157 --- 1.2 1996/6/10 (1st anniversary release)
4159 Added Summary record syntax. Lightly tested.
4161 Added OPAC record syntax. Untested.
4163 Added ResourceReport service encoders/decoders. Untested.
4165 Fixed bug in z_Unit - wrong tagging on unitSystem.
4167 Fixed bug in the DiagRecs decoder.
4169 Added options for max PDU size and session timeout to frontend-server.
4171 Added documentation of query-language parsers and other supporting utilities.
4173 [frontend-server] Added Attribute set to the bend_scanrequest API.
4175 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4176 surrogate diagnostics were generated.
4178 [retrieval] Allow multiple local values for attribute.
4180 [retrieval] Allow multiple attributes per element in .abs files. index type.
4182 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4184 --- 1.1pl2 1996/4/10
4186 Minor changes, mostly specific to Zebra's requirements (retrieval)
4190 Repaired bug in frontend server when running multiple listening
4191 endpoints in dynamic mode.
4193 z_External() now won't break if a known, ASN.1 value comes encapsulated
4194 in an octet-string. The value will pass through unmodified in an Odr_oct.
4196 Added a bit of code to the demo client to decode & display
4197 ASN.1-structured records represented in the octet-aligned branch of
4198 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4200 Added z_ext_getentbyref() to the ASN module. Doc updated.
4202 * Completed the SCAN definition in the ASN module. This may break SCAN
4203 code based on older YAZ-versions at compile-time. The fix is easy -
4206 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4207 under the SCAN definition. Remember to initialize this, server-people.
4209 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4210 that this does not extend to ODR and ASN.
4212 Comstack allows insertion of established socket (primarily for
4213 inetd-operation of servers). Doc updated.
4215 Front-end server can now start from the inetd in TCP mode. Doc
4218 --- 1.0pl4 1996/1/24
4222 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4223 the rank and record number.
4225 Adjustments to the frontend server.
4227 Fixed diagnostic BER dumper. It ignored the file argument.
4231 Various changes to retrieval module.
4233 Changed the union discriminators of the protocol files from enums to
4234 ints paired with #defines.
4236 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4239 *Changed operator in the RPN structure to 'roperator', again to avoid a
4242 Fixed problems in Explain decoders/encoders.
4244 --- 1.0pl2 1995/12/6
4246 Memory bug in log module fixed.
4248 --- 1.0pl1 1995/12/5
4250 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4252 Bug in Explain DatabaseInfo module fixed.
4254 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4258 The shift to v1.0 signals that we now consider the *core* functionality
4259 of YAZ reasonably stable (the core being more or less equivalent to
4260 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4261 tested (Explain not at all - though that will happen soonish).
4263 Minor changes to code to support Windows port.
4265 Various minor changes after we're getting to use GRS-1 & co. more.
4267 Added Espec-1 format.
4269 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4270 of the protocol and it cannot be selected when encoding (maps into 'string'
4271 when decoding). Needed to talk to some servers.
4273 Demo client can request simple element set names.
4275 Added Diagnostic Format encoders/decoders.
4277 Added simple Close handling to frontend server (no hooks for resource
4278 reporting yet), and demonstration client.
4280 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4282 --- 1.0b3 1995/08/24
4284 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4285 handled incorrectly when records were requested in the searchResponse. This
4286 will only affect you if you use the frontend-server.
4288 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4289 Test-client will ask for and print GRS1. Ztest will return dummy records
4292 Added Explain encoders/decoders to the service-level API. Untested.
4294 Added Extended Services: Item Order encoders and decoders to the Service-
4295 level API. Untested. We could use a recent copy of the pertinent bits
4296 of the ILL protocol to add those bits.
4298 Added diagnostic format 1 encoders/decoders to the service-level API.
4301 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4302 odr_cons.c, which causes a more correct output.
4304 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4305 was always set to 0 when no records were requested in the searchRequest.
4307 * Added better external-handling. This shouldn't harm old code that
4308 *encodes* externals. It can break code that looks for a
4309 'single-ASN1-type' representation, since those types that are known
4310 are now decoded immediately. Look at the SUTRS sample code in
4311 seshigh.c and client.c. Documentation updated.
4313 Handling of structured records in bend_fetchresponse. Length -1 marks
4314 structured record, type is deduced from format field.
4316 --- 1.0b2 1995/06/27
4317 Fairly quick maintenance release to add SUTRS support.
4319 Fixed handling of SUTRS records in the demonstration client.
4321 * Added format field to the bend_fetchrequest and bend_fetchresponce
4322 structures of the backend API (frontend server). When the record is
4323 returned, the value of the format field is mapped to an OID. The
4324 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4325 of the record. The special value VAL_NONE in the bend_request means
4326 that no specific format was requested by the client. Documentation
4327 updated accordingly. Test server (ztest) will return a fixed dummy
4328 SUTRS record if your client requests SUTRS.
4330 Documentation updated accordingly.
4332 You can now set external libraries and RANLIB support in the top-level
4336 First public release.
