3 wrbuf_cstr: fix off by one error.
5 wrbuf_buf: make it always return non-NULL
6 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
10 cql_transform: Use WRBUF for addinfo member
11 rather than a xmalloc'ed one. The primary reason for this is make the
12 system slightly less vulnerable to threading issues. YAZ-756
14 Fix assert in ZOOM when http connect fails YAZ-757
18 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
20 wrbuf_cstr: make it thread safe YAZ-753
22 yaz_log_init_file may take fd=<no> to open log file at the FD given.
26 Offer new utility function zget_AttributeList_use_string.
28 New conversion step, solrmarc, for record conversion module.
32 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
33 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
38 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
39 The standalone ZOOM sort was completely broken since 5.0.13.
41 ZOOM: generate event Connect rather than None for partial connect
42 (in fact getaddrinfo resolving).
44 ZOOM: only supply clientIP for InitRequest. Rather than for all
47 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
49 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
50 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
51 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
53 New "Facets" section in the documentation.
57 Call exsltRegisterAll in yaz_init_globals, so that all applications
58 using YAZ will have EXSLT things enabled.
60 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
62 Update various URLs to the re-organized SRU pages at LoC.
66 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
69 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
70 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
71 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
76 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
80 Fix gcrypt not properly initialized YAZ-740.
84 Describe memcached option for ZOOM.
86 ZOOM: throw present request out of range again YAZ-739
87 Was removed in YAZ 5.0.13.
91 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
92 with localtime_r when threads + fork is used (such as Metaproxy).
94 yaz-config: quote some RHS values (that might include blanks)
96 zoomsh: shows SearchResult-1
98 zoomsh: sortby command
100 zoomsh: use proper list of connections and result sets YAZ-725
102 Avoid yaz_log in sigterm handler for GFS YAZ-737
103 Logging is still performed, but outside sig handler.
105 New ZOOM C feature: result-set caching with memcached. Example:
106 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
108 Remove SSL via OpenSSL support YAZ-732
109 Also deprecate two functions from comstack that aren't working with
110 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
112 Revert "Bison: use %name-prefix directive rather than -p option"
114 --- 5.0.12 2014/01/22
116 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
118 SRU GET/Solr base URLs may hold additional ?args YAZ-729
119 ZOOM option extraArgs already does this, though. It seems useful
120 when dealing with Solr targets to limit by filter, eg.
121 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
123 Remove #fragment for HTTP request encoding YAZ-730
125 Doc: Update list of DLLs/LIBs
127 Doc: update href link to Unix utils and Git.
129 --- 5.0.11 2014/01/15
131 ZOOM: fix "lost connection" problem with servers that uses both squid
132 and another proxy behind it that returns Location headers with relative
135 zoomsh: do not use readline for stdin (no tty) YAZ-724
136 Just use fgets in that case. If the user hits Ctrl-D a new-line
139 zoomsh: empty command ignored YAZ-723
140 rather than performing exit of zoomsh.
142 yaz-url utility offers option -v to enable verbose mode.
144 yaz_url uses yaz_check_location and offers verbose mode.
146 Add new function yaz_check_location.
147 This function gets an absolute URI from Location (HTTP redirect).
149 cookie API: introduce yaz_cookies_reset
151 Update cql.y for newer bison YAZ-720
152 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
153 longer supported. Instead one must use %lex-param and %parse-param .
155 --- 5.0.10 2014/01/09
157 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
160 rpn2solr: support truncation left(2), left&right(3) YAZ-718
162 Mention SRU version 2.0 in yaz-client man page.
166 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
171 Make cs_parse_host public.A
173 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
174 introduced in YAZ 5.0.6.
178 Fix buffer corruption for yaz-ztest record fetch.
182 Allow yaz-ztest to return user-defined records (one record per file).
183 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
185 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
186 Use the stream write instead of odr_printf which has a 4K tmp buffer.
188 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
192 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
193 can read and write this format. For record format JSON, yaz-ztest returns
194 MARC-in-JSON records.
196 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
197 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
201 Improve error reporting for ICU chains YAZ-707
202 Report config element+rule when ICU status is "failure".
204 ZOOM: stop fetching if present response has no records YAZ-710
205 Some targets return less records than their hit count would suggest.
206 This prevents ZOOM from continuing to fetch records if any present
207 response has 0 records in the response.
209 Ensure that GFS calls exit if any listener fails YAZ-710
210 Before, if XML config was in use, it would start the default
215 yaz-ztest: -V shows version (like yaz-client -V)
217 New iconv encoding: danmarc YAZ-692
219 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
221 daemon: only wait for immediate child rather than all children. YAZ-704
223 yaz-client: fix setting of SRU record schema. If scheme was unset, it
224 could lead to invalid memory reference.
228 yaz-ztest returns schema for MARCXML test records. SRU require that
229 recordSchema for records.
231 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
232 instead of non-surrogate diagnostic. This is a per-record failure.
234 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
235 may refer to multiple listeners now. Attribute listenref is a comma separated
238 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
239 option is given for GFS, the dirname of filename (for -f) is used
240 as prefix for options such as cql2rpn, ccl2rpn, etc.
242 Content-Type charset fixes YAZ-701 . Do not inspect charset in
243 Content-Type header for SOAP when decoding SRU. The payload (XML)
244 itself tells what encoding it is. In response, never supply encoding
245 in Content-Type. The response payload (XML) tells what it is (with no
246 encoding in XML it's UTF-8).
248 HTTP decoding: allow blanks in URL paths YAZ-700
252 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
253 and facets. Ensure recordData and recordSchema are always present in
254 record element, because they are required.
256 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
259 Simplify in a lot of places using odr_strdupn.
261 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
265 Increase various buffers in GFS's statserv_options_block
266 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
267 This change makes many type-casts redundant, and, thus simplifies code.
269 Remove last bits of WAIS support.
271 Remove member 'size' from Odr_oct.
273 Slim down the public part of 'struct odr'. Most elements are not part
274 of struct Odr_private.
276 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
277 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
278 In particular facets are supported in both client - and server side.
279 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
280 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
281 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
282 both request/response). This is what a search handler in the GFS
283 will see (regardless of whether operating in SRU mode or Z39.50).
285 Changes to the srw.h (SRU/Solr) definitions include:
286 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
287 (char*), which replace union query and query_type (int). This is because
288 SRU 2.0 supports a queryType parameter. This also means that, to carry
289 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
290 x-pquery=PQFstring (extention parameter). The extension parameter
292 - New element, packing, that has information about SRU
293 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
295 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
297 New element, packing, in Z_SRW_explainRequest.
299 New elements in Z_SRW_scanRequest, queryType and scanClause.
300 These replace query_type and scanClase untion. This is similar to what
303 --- 4.2.69 2013/10/01
305 GFS: log when closing down - at least SIGTERM YAZ-684
306 Also change formatting WRT PID logging a bit.
308 Improve display of MARC records with multi-byte subfield IDs YAZ-695
309 In some rare cases subfield identifiers are multi-byte characters.
310 This will try to deterime length of those and split accordingly.
311 This affects display in line mode as MARCXML/MarcXchange. The encoding
312 of ISO2709 is the same.
314 Change inp argument to const for yaz_read_UTF8_char.
316 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
318 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
320 Better check of marc leader info YAZ-691
321 Problem is that some systems generate MARCXML/MarcXchange with
322 funny headers. These will not work if encoded as ISO2709.
323 Some tests produce new output, due to updated warning messages
325 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
327 yaz-client: display MAB records YAZ-689.
328 Thanks for Heiko Jansen for this patch.
330 New utility z_get_HTTP_Response_server which allows both HTTP server name
331 and HTTP server URL to be given in response.
333 Debian: do not depend on obs tcl8.3.
335 Debian: do not depend on obs libicu36-dev.
337 --- 4.2.68 2013/09/23
339 GFS: pass additionalSearchInfo to search memeber search_input if
340 given. Otherwise pass otherInfo. Request for facets and other search
341 related things will be passed there in future versions of YAZ.
343 New ZOOM setting, authenticationMode, which allows authentication
344 paramters to be encoded in the URL rather than via HTTP Basic auth.
347 rpn2solr: fix nested AND/OR handling. YAZ-685
349 Add comparison routines for some Z-types, such as NamePlusRecord,
350 RPNQuery, Query, RecordComposition and OtherInformation.
352 --- 4.2.67 2013/09/19
354 Don't decode MAB as MARC. Just like we don't attempt to decode
355 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
357 CCL: allow quoted terms for date ranges. YAZ-681
359 Introduce ccl_parser_qual_search. This function makes old function
360 ccl_qual_search, from YAZ 2, available again.
362 Add yaz_facet_list_to_wrbuf. YAZ-683
364 --- 4.2.66 2013/09/11
366 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
367 schema was given for search. YAZ-675
369 Add Solr date range searches. YAZ-621
371 --- 4.2.65 2013/08/22
373 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
375 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
377 ISO2709/MARC parse most octet aligned records; not just those that
378 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
379 MARC parse more records instead of just dumping as is. YAZ-670
381 ZOOM: proper caching for variations of record schema. YAZ-671
383 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
385 --- 4.2.63 2013/07/17
389 --- 4.2.62 2013/07/11
391 New utility z_get_HTTP_Response_details - an extended version of
394 New utility yaz_url_get_error which returns error message of last
395 failed yaz_url_exec call.
397 yaz-url and url functions: allow max HTTP redirects to be controlled.
399 New functions yaz_file_glob2, yaz_xml_include_glob.
400 These functions takes a flags parameter, which, for now only controls
401 whether to fail inclusion of a non-existing file (without glob
402 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
404 --- 4.2.61 2013/06/20
406 For MARC XML parsing, allow record without leader. A fake/default leader
407 is inserted and a warning is tagged with the record.
409 ICU: fix leak in in icu_iter_get_org_info.
411 --- 4.2.60 2013/06/14
413 ICU: fix bug in icu_iter_get_org_info (un-init variable).
415 --- 4.2.59 2013/06/11
417 Implement z_HTTP_header_remove.
419 --- 4.2.58 2013/06/11
421 ICU: Disallow 0 ptrs for some ICU string utilities.
423 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
424 returns original tokens (before normalization).
426 CCL: avoid z39.58/regex truncation when not needed. Apply only the
427 conversion of those masks, when absolutely necessary.
429 CCL: configurable masking character - @mask. Default masking character
432 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
433 full response anyway, so a Transfer-Encoding header will obstruct the
436 --- 4.2.57 2013/05/15
438 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
439 picking a socket. Problem is that some systems has IPV6 support, but
440 we can't create sockets for them, so we pick AF_UNSPEC first.
442 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
443 use content_len to determine resulting Content-Length in HTTP response
444 and NOT Content-Length supplied in headers by user.
446 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
447 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
449 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
452 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
453 with big endian and unsigned char (by default).
455 --- 4.2.56 2013/04/26
457 Fix yaz-client connect (crash in 4.2.55).
459 --- 4.2.55 2013/04/26
461 Fix proxy/host problem for ZOOM that could occur if unix sockets
464 New Debian package libyaz4-dbg.
466 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
467 differently in tcpip_close.
469 --- 4.2.54 2013/04/17
471 Windows installer of YAZ includes YAZ4J as a component.
473 CQL: allow "extra terms" again, by default. Thus, the CQL parser
474 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
475 and earlier. CQL parser may operate in strict mode where queries
476 not conforming to the standard BNF are rejected (syntax error).
477 Whether the CQL parser operates in strict mode is controlled with
478 cql_parser_strict . Strict mode enabled with option -S for utilities
479 cql2pqf and cql2xcql .
481 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
483 --- 4.2.53 2013/04/10
485 New charset, MARC-8c, which is like MARC-8 but allows control characters
486 0x01 through 0x1F, except ESC to be passed through verbatim.
488 Fix a problem with duplicate sub field character in MARC output. Problem
489 happened only when output was MARC-8 encoded.
491 --- 4.2.52 2013/04/03
493 yaz-ztest: Use hash for fake hit count. Before, random number was used.
494 This is problematic for unit tests using yaz-ztest. This patch also makes
495 a hash for CQL queries. For RPN, any term with a leading digit will be
496 treated as pseudu hit count (to force any particular hit count by a client).
498 yaz-ztest: return unique MARC dummy records. Beyond record offset
499 24, the author surname is patched with offset to make all records
502 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
503 on system wide default (/proc/sys/net/ipv6/bindv6only).
504 @4 binds to IPV4 only. @6 binds to IPV6 only.
506 Update CQL API documentation a bit
508 CQL: don't accept extra terms for queries. Makes the CQL parser
509 stricly conformant to the standard.
511 --- 4.2.51 2013/02/12
513 GFS: scan handler gets extra_args from request and may return extra
514 response data . That's for SRU only.
516 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
518 --- 4.2.50 2013/01/30
520 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
522 OPACXML: sync spelling of availabilityDate in XML to that of Schema
523 opaxxml.xsd. The schema had the correct spelling of this member always.
524 The ASN.1 was mis-spelled and still is (API change) - we are
525 not changing this. However, the OPAC to XML conversion had yet
528 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
531 New function, z_ext_record_oid_nmem, which is similar to
532 z_ext_record_oid but takes NMEM rather than ODR
534 --- 4.2.49 2013/01/18
536 ICU: New conversion element 'join' which joins tokens into one
537 with a custom character given by rule attribute.
539 --- 4.2.48 2013/01/10
541 New GFS search member: present_number. This is a hint to the
542 search handler how many records are going to be fetched immediately
543 following search. There's no guarantee that it's going to be the case,
544 since it depends on hit count (for Z39.50 piggyback) and whether errors
547 Make a few functions static (private). The functions getbyte_stream,
548 ungetbyte_stream and yaz_gets are now private. They were never declared
551 yaz-marcdump: exit(5) for serious decoding errors
553 ISO2709 decoding: be more picky WRT header
555 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
556 was only used as to indicate that next-result-set-position should be
558 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
559 Based on patch from Ashley Sanders.
561 Make some functions static/private in PQF parsing. Those functions were
562 never declared in a public header and so should not be in use by
563 applications based on YAZ.
565 --- 4.2.47 2012/11/23
567 ZOOM: special options to control APDU logging.
568 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
569 logging of APDUs until "saveAPDU" option is set again. If logging is
570 already enabled the effect is that current APDU buffer is cleared.
571 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
572 logging (default behavior on new connection).
573 The APDUs sent/received can be obtained by using
574 Using ZOOM_connection_option_get(c, "APDU") or
575 ZOOM_connection_option_getl(c, "APDU", &l).
577 GFS: relay implementation_version from backend
578 From 3.0.40 and later, implementation_version from backend was
579 not used in init response at all.
581 --- 4.2.46 2012/11/15
583 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
584 mode at all. Probably never did.
586 Make a new version of ztest.pem that, at least, is not expired.
588 --- 4.2.45 2012/11/13
590 Fix description of CCL directive 'case'.
592 More tight checking of form arguments (yaz_uri_to_array). Makes
593 YAZ better at rejecting big and/or bad POSTs.
595 SRU decoding does not report more than up to 10 invalid arguments.
597 rpn2cql: less quotes in generated terms. Semantics unchanged, but
598 it's prettier this way.
600 --- 4.2.44 2012/10/25
602 New utility yaz_decode_init_diag. Defined in proto.h.
604 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
605 given for unix local socket.
606 The COMSTACK string for doing so is:
609 unix:/myfile:tcp:localhost:9999/mybase
610 unix:/myfile:localhost:9999/mybase
611 unix:/myfile:http://fakehost/mybase
613 debian: Use dpkg-buildflags in build process.
615 --- 4.2.43 2012/10/19
617 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
618 global's SRU service uses a recordPosition scheme starting from zero.
619 First record's position should be one
620 according to the standard.
622 --- 4.2.42 2012/10/18
624 Allow more namespaces for SRU. This is to allow, for example, an
625 incorrect namespace returned from server
626 http://services.igi-global.com/sru .
628 Minor fixes for compilation on Windows.
630 --- 4.2.41 2012/10/11
632 daemon: log total number of bad signals from child on stop so that it
633 is more easy to spot problems with child worker processes.
635 retrieval: empty backend name attribute omits element set
636 from being used in retrieval.
638 --- 4.2.40 2012/10/04
640 Implement Solr sort strategy "solr", similar to sru11 sorting.
641 This will implement the correct parameters on Solr requst to do
644 --- 4.2.39 2012/09/28
646 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
649 MARC: Extra/missing indicator handled for MARCXML.
650 The indicator length is given in header and is the same for the
651 whole record. If attributes ind1, ind2 are missing, then content
652 character defaults to blank. Extra indicator attributes (beyond)
653 indicator length are treated as an error.
655 Reformat: delete trailing whitespace
657 --- 4.2.38 2012/09/17
659 MARC: fix non-ASCII characters for leader. This is to ensure we can
660 generate XML in UTF-8.
662 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
663 in one node with structure word.
665 --- 4.2.37 2012/09/04
667 yaz-json-parse: JSON output may be pretty printed by using option
670 Increase default value of max message for Z39.50 Init for GFS, ZOOM
671 and yaz-client. Old value was 1 MB. New value is 64 MB.
673 --- 4.2.36 2012/08/22
675 yaz-client: don't display bogus records from SRU servers. Some SRU servers
676 return more records than given by *maximumRecords*. Skipping those in
679 record_render: simplify buffer return handling and fix at least one bad
680 memory reference, that broke the test_embed_record sometimes.
682 Allow http://user:pass@host notation for yaz_url_exec.
684 zoomsh: allow shell command to be executed. Via the system(3) call.
686 yaz_poll: Allow num_fds == 0
688 yaz-client: fix bad encoding of "itemorder item". The itemorder
689 item <no> - command forgot to use length of encoded Item Request
690 package. Error present since YAZ 3.
692 yaz-ztest: fix bad usage of session handle. Bug was introduced when
693 result sets were saved (271a9c83).
695 SRU recordPacking: guess record packing in response rather than looking
696 at the recordPacking element which, OF COURSE, changed semantics in SRU
699 Decode SRU 2.0 responses. The official namespace for responses, according
700 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
701 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
702 nature.com's server, however, usee namespace
703 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
704 we are now using a glob-expr to match up the namespace. ZOOM C and
705 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
706 I can not find a single real example showing the "real" namespace in
707 the documentation from OASIS. The namespace for requests is different
708 from responses, but this is not added to YAZ yet, when we don't encode
711 --- 4.2.35 2012/06/26
713 zoom/record_render: add support for Base64 decoding fo MARC records
714 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
715 which will decode base64 + ISO2709 marc-8 encoded material from text node
718 --- 4.2.34 2012/06/07
720 Add missing definitions ZOOM_resultset_get_facet_field_by_index
721 and ZOOM_resultset_facets_names.
723 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
726 Change APDU dump printing to avoid long leading blanks. For levels 16
727 or larger the level is shown and the indentation is truncated but
728 recursed with modula 8. This makes it still reasonable easy to read
729 - even for nested BER dumps.
731 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
732 return 0 (incomplete package) in case where the BER package was
733 considered too nested (return value of -2).
735 dumpber: lines of level 15 are not indented further. Two spaces per
736 indentation; indentation 15 or more is indented to a fixed indentation
737 and augmented with a level=<no> indication.
739 zoomsh: increase max size of command+args
741 GFS: No limit in RPN buf size in CQL to RPN conversion.
743 --- 4.2.33 2012/05/09
745 New function for daemon utility, yaz_daemon_stop .
747 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
749 --- 4.2.32 2012/04/25
751 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
752 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
754 --- 4.2.31 2012/04/23
756 YAZ daemon utility relays SIGUSR1 to child process.
758 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
759 would result in en empty database list - which in turn would result in
760 encoding failure for search.
762 Fix reading beyond string in yaz_sort_spec.
764 --- 4.2.30 2012/04/11
766 Add two new SRU diagnostics:
767 236: Access to specified database denied
768 1015: Init/AC: Maximum number of simultaneous sessions for Userid
770 Document the very useful ZOOM-C option "apdulog".
772 CQL to RPN: term may be passed through verbatim. This is enabled with
773 truncation.cql . The assumption being that the term is already CQL.
775 --- 4.2.29 2012/03/20
777 record_conv: leader spec may be given for marc element.
778 The leader spec is given as attribute leaderspec for element marc.
779 For example to convert a MARC21 record from MARC-8 to UTF-8:
780 <marc inputformat="marc" outputformat="marc"
781 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
783 record_conv: allow user-XSLT params. For example:
784 <xslt stylesheet="MARC21slim2DC.xsl">
785 <param name="myparameter" value="myvalue"/>
786 <param name="otherparameter" value="othervalue"/>
789 record_conv: fix error handling for missing marc charsets.
791 CQL: fix extra terms in wrong order.
793 --- 4.2.28 2012/03/06
795 record_conv: modify new API for conversion types. The conversion types
796 may be passed in new functions yaz_record_conv_configure_t and
797 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
799 Avoid mixed statement/variable declare; fixes compilation with Visual
802 --- 4.2.27 2012/02/28
804 Add non-standard SRU diagnostic: 235: "Database does not exist".
805 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
806 Update SRU to Bib-1 diagnostic maps accordingly.
808 CCL: add two new diagnostics for unsupported masking. The new
809 diagnostics are: "Embedded truncation not supported" and
810 "Single charcacter mask not supported".
812 --- 4.2.26 2012/02/23
814 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
816 --- 4.2.25 2012/01/11
818 Build YAZ for Ubuntu Oneiric.
820 CCL: allow parantheses for proximity operands. For example CCL query
821 (a) % (b) is now allowed.
823 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
824 marked dead, rather then being destroyed. If not, the session memory is
825 being free'd before the search/scan handler is finished. Also destroy
826 'request' memory in request_release rather than in various places,
827 which resulted in leaks from time to time.
829 --- 4.2.24 2011/12/21
831 cql_sortby_to_sortkeys: honor sort prefix.
833 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
834 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
835 The rpn2cql family of functions now always returns quoted CQL terms.
837 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
839 --- 4.2.23 2011/12/15
841 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
842 sequence is treated as one. For example, &&a=b&&&c& is identical to
845 --- 4.2.22 2011/12/05
847 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
848 APDUs for a connection to a WRBUF.
850 --- 4.2.21 2011/11/23
852 Fix cql_sortby_to_sortkeys. Completely broken before.
854 Make CCL's @truncation work again.
856 --- 4.2.20 2011/11/09
858 New ZOOM connection setting: tproxy. It's like proxy, but does not
859 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
860 to set resolved address + port for a connection outside ZOOM itself.
862 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
864 --- 4.2.19 2011/11/07
866 Fix uninitialized variable in Solr spell support (could cause SEGV
867 for SRU response decoding).
869 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
870 back-end's addinfo through into the ZOOM response addinfo.
872 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
873 they are separated by a colon and a space rather than simply
876 --- 4.2.18 2011/10/28
878 Add support for Solr spell-checking/suggestions through ZOOM.
879 If a Solr target has been configured correctly for spelling-checking
880 and suggestions, these will now be returned on the ResultSet option
881 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
883 --- 4.2.17 2011/09/28
885 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
886 with a flag whether to substitute escape sequences or not.
888 --- 4.2.16 2011/09/22
890 Fix nmem_strsplit_escape to substitute escape char properly.
892 New option for zoomsh -e , which makes it abort on first error and
893 return process exit code to indicate success/failure.
895 YAZ options utility supports special option -- which makes all it treat
896 all following arguments as non-options.
898 --- 4.2.15 2011/09/16
900 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
901 searched if absolute filename is given.
903 Fix conv_xslt() error-reporting when stylesheet is not found.
904 (The value of fullpath is meaningless in this situation.)
906 --- 4.2.14 2011/09/07
908 Fix problem in CQL sort node creation: un-initialized memory.
910 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
911 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
912 CQL sortby depending on whether Type-1 or CQL is actually sent to the
915 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
916 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
918 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
919 will make it possible to use both single-character mask (#) and wildcard (?)
920 in CCL . Throw diagnostic for left truncation because that is not supported
923 --- 4.2.13 2011/09/01
925 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
926 cases using escapes (\-sequences) and masking.
928 PQF parse fix: A trailing backslash followed by end-of-string (\0)
929 would result in a read one byte beyond string.
931 rpn2ccl may use Z39.50 masking for terms (t=z).
933 ICU check fix. Don't include library -lCrun on Solaris, unless present.
935 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
936 not --cppflags (which seeems like an error in icu-config).
938 --- 4.2.12 2011/08/27 RPM package only
940 cql2ccl: fix conversion of terms: operator characters were not
943 --- 4.2.11 2011/08/25 RPM package only
945 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
946 CCL parser will map both # and ? to their regular expression
947 quivalents (. and .*).
949 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
950 of reserved CQL characters.
952 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
953 is, so that they are passed through.
955 --- 4.2.10 2011/08/24
957 ZOOM SRU mode: more aggressive re-connect.
959 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
960 made available as a utility function, declared in <yaz/logrpn.h>
962 rpn2cql_structure() supports proximity nodes (except that the Type-1
963 proximity node's "exclusion" binary is ignored, as there is no way to
964 express that in CQL). Fixes bug #4564.
968 Fix SEGV that could occur if set command of zoomsh was given without
969 value (2nd argument).
971 Fix SEGV that could occur if unsupported transport was given for
972 COMSTACK - say https (when SSL was unavailable).
974 Build yaz-url on Windows too.
978 New utility to get web content. Header is url.h. A command line tool
979 yaz-url is part of the distribution and packages.
981 Fixes for SSL COMSTACK (when gnutls is in use).
983 New functions yaz_base64{encode,decode}. Header is base64.h.
987 ZOOM C includes HTTP response buffer as additional info if it fails
988 to decode the SRU response.
990 Make wrbuf_json_puts available.
994 zoom: throw diagnostic for invalid value for option "sru". Before a
995 bad SRU request was sent.
997 Adding new utility wrbuf_vp_puts.
999 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1001 --- 4.2.5 2011/07/21
1003 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1004 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1005 redirect was used at the same time.
1007 MARC line mode decoding: be less picky about length given - first
1008 5 digits of header that is.
1010 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1012 Changes to decoding of SRU records: a record with recordPacking=xml is
1013 modified with a new root element <yaz_record> if the recordData contains
1014 multiple children elements. This is to make the record XML parseable
1017 RPN to Solr conversion: encode special characters.
1019 Generic Frontend Server: fix uinitialized member, stepSize.
1021 --- 4.2.4 2011/06/21
1023 Fix a bug in SRU decoding of records.. The database records stored
1024 had un-initialized memory, but it would only be seen with yaz_record_render
1025 and type_spec="ext" .
1027 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1029 --- 4.2.3 2011/06/17
1031 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1033 --- 4.2.2 2011/06/10
1035 Add new utilities to convert from CQL to CCL . These utilities have
1036 prefix cql_to_ccl defined in cql.h.
1038 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1039 lead to memory heap corruptions when ICU utilities were in use.
1041 --- 4.2.1 2011/06/07
1043 Make compilation work without Libxml2.
1045 yaz-client: remove redundant blanks in display of searchResult-1 term
1048 --- 4.2.0 2011/05/18
1050 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1051 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1053 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1054 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1055 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1056 Note that the CQL sortby spec is only converted when the GFS is already
1057 converting from CQL to RPN (cql2rpn element).
1059 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1060 specify whether to collapse delimitors or not. The existing nmem_strsplit
1061 do collapse (collapse parameter = 1).
1063 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1065 Rename internal func yaz_use_attribute_create. While non-static, this
1066 function is not declared in a public header.
1068 --- 4.1.7 2011/03/15
1070 Add -lCrun when linking with ICU on Solaris.
1072 More quicks character set conversions for OPAC records.
1074 --- 4.1.6 2011/03/10
1076 fix problem with record_render: records were converted (character set
1077 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1079 --- 4.1.5 2011/03/08
1081 SRU: add methods for handling DADS SRU-proxy facets.
1083 Separate OPAC record character set for ZOOM_record. yaz_record_render
1084 allows a character set given as charset=from/opacfrom,to where 'from' is
1085 the character set of a bibliographic record, 'opacfrom' is character set
1086 of OPAC record and 'to' is the target character set.
1088 --- 4.1.4 2011/02/21
1090 yaz-client: show may XML format records. Command show followed by 'format'
1091 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1094 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1097 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1099 --- 4.1.3 2011/01/27
1100 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1102 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1103 this package can be distinguished from other vendors.
1105 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1106 as determined by configure
1108 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1110 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1111 returns no error and no record, the present request is considered
1112 partial (only a subset of the records could be returned by backend), and
1113 so it is appropriate to set Present Status to partial-4.
1115 --- 4.1.2 2010/11/02
1117 Move yaz-config man pages to section 1.
1119 More documentation about Solr.
1121 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1122 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1123 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1124 peers on some Linux systems. However, in general that does not work
1125 so YAZ can not rely on that to work. Debian changed behavior in this
1126 respect from Debian lenny to Debian squeeze (still testing as of Oct
1128 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1130 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1132 --- 4.1.1 2010/10/05
1134 Fix yaz-config output: echo_source not set correctly by configure.
1136 --- 4.1.0 2010/10/05
1138 Solr Web Service support for yaz-client and ZOOM.
1140 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1142 --- 4.0.12 2010/08/17
1144 Z39.50 facet support. Facet specifications are passed for search in
1145 other-information with ASN.1 as defined in facet.asn and OID
1146 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1147 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1148 3 is limit (number of entries to get in response). yaz-ztest returns
1149 dummy facets if a client asks for them.
1151 --- 4.0.11 2010/07/09
1153 CCL fixes: bug 2895 and bug 3539.
1155 GR1-display: add comma in display - was removed by mistake in
1158 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1160 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1162 --- 4.0.10 2010/06/18
1164 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1165 result set from a connection. The result set will be on its own
1166 thereafter; no operations on it will perform retrievals from a target.
1167 Only cached copies are returned.
1169 ZOOM C:fix case for HTTP servers responding with Connection:close.
1170 Ensure that if there is a current task it is resumed (like fetching
1171 more records in a result set) . Bug #3484.
1173 PQF parser: use odr_atoi for Odr_int (not atoi)
1175 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1176 values that contain any non-digits are treated as string attributes
1177 (previously decoding only checked for leading character ([0-9]). PQF
1178 encoding: attribute string values are not surrounded by double-quotes.
1180 --- 4.0.9 2010/05/21
1182 New utility for managing threads - thread_create.h.
1184 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1185 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1186 but YAZ' implementation do.
1188 Fixes for yaz_cond-functions on Windows 7.
1190 DLL export more symbols.
1192 zoomsh: show record do NOT render opac.
1194 Remove *.la files from Debian and RPM packages.
1196 --- 4.0.8 2010/05/11
1198 Debian package libyaz-dev depends on libgnutls-dev again (was
1199 removed in YAZ 4.0.6, but due to Libtool it is still needed
1200 even though yaz-config do not list libgnutls libs).
1202 ZOOM: Use only one WRBUF for returning string results for
1203 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1205 ZOOM: ZOOM_connection do not use a shared pointer to
1206 ZOOM_resultset after ZOOM_resultset is destructed by
1207 user. Reverts to YAZ 4.0.4 behavior.
1209 --- 4.0.7 2010/05/04
1211 record-conv: fix problem with at least one XSL conversion -
1212 due to probably incorrect usage of XML XSL documents.
1214 --- 4.0.6 2010/04/29
1216 Fix yaz-config for static mode and the use of SSL (gnutls).
1218 --- 4.0.5 2010/04/29
1220 Forward decl timeval struct in mutex.h and gettimeofday.h.
1222 yaz-config: fix 'static' mode linking.
1224 --- 4.0.4 2010/04/28
1226 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1227 are wrappers for pthreads or Windows. For Windows these are put in
1228 a separate DLL: yaz_cond4.
1230 libyaz.la (whole source) is compiled with thread. If thread support
1231 is enabled enabled, all source of YAZ is compiled with treading support.
1232 This allows core utilities such as yaz_log to use thread facilities.
1233 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1234 thread utilities. This commit moves mutex utilities (mutex.c) from
1235 libyaz_server.la to libyaz.la.
1237 yaz-json-parse displays leading text until error.
1239 --- 4.0.3 2010/04/09
1241 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1242 patch from Giannis Kosmas.
1244 SRU: no longer URL encode SRU database. The URL for an SRU server is
1245 a URL and such is alreeady encoded - at least when given with leading
1246 http:// or https://. This reverts behavior to YAZ 3.0.50.
1248 Support for new MARC XML notation TurboMARC which like MARCXML is a
1249 complete representation of MARC/ISO2709.. This one, however, is more
1250 compact and allows for faster processing with XSLT. TurboMARC can be
1251 used in the marcdisp.h API, from the yaz-marcdump utility and from
1254 yaz-ztest can be configured - via the database - to perform certain
1255 delays when it performs operations search, present and single record
1256 fetch. This allows testers to make yaz-ztest act as a real or even slow
1257 Z39.50 server. Refer to the yaz-ztest man pages for details.
1259 --- 4.0.2 2010/03/09
1261 wrbuf_destroy allows NULL WRBUF passed to it.
1263 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1265 Add ZOOM_connection_close.
1267 No fixed size buffers for ZOOM shell - bug #3257.
1269 tstodr: make it work on s390 platform.
1271 New icu iterator-functions. The new icu_iter-functions makes it possible
1272 to use ICU chains from many threads.
1274 yaz-client: better syntax check for show command.
1276 --- 4.0.1 2010/01/26
1278 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1281 New simple local-file XML include facility which allows file glob-patterns.
1282 Refer to yaz/xml_include.h.
1284 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1287 ZOOM_record_get supports new parameter "format" which makes it format XML
1290 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1291 JSONText in ECMA-262) is JSONValue, not JSONObject.
1293 --- 4.0.0 2010/01/20
1295 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1296 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1298 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1299 POSIX/Unix builds .so with major version 4.
1301 Remove old LOG_-defines from log.h. They have been obsolete and
1302 undefined by default for the last 5 years.
1304 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1306 GFS: Remove socket (int *fd) from search_rr handler. The socket
1307 descriptor ptr is a facility that allowed a search handler to supply
1308 a socket which would serve as a callback - when search was complete.
1309 This facility has now been in use for years.
1311 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1312 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1313 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1314 returns 'const char *' rather than 'char *. The returned string is
1315 read-only and should not be modified by applications. COMSTACK cs_close is
1316 now a void function - it no longer returns int. No applications check for
1317 the value and the implementations has always returned 0.
1319 ZOOM: use size_t for scan hit counts and str size. Functions
1320 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1321 occ (hit count) and len (string length) are now of type size_t pointer
1322 rather than int pointer. This is to be able to represent large hit counts
1323 and to also just to use the proper type for string length (strlen result).
1325 New JSON parser. Refer to include/yaz/json.h .
1327 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1328 Used to be int in some cases. Many wrbuf_-functions used to return an int
1329 indicating some length.. These return values were never used. And so they
1332 ODR: odr_malloc, odr_total now takes size_t for size.
1334 clone_z_type: fix leak; occurred for encoding failures.
1336 --- 3.0.52 2009/12/03
1338 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1339 bug was introduced in 3.0.51.
1341 --- 3.0.51 2009/12/02
1343 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1345 tcpip comstack: fix leak for getaddrinfo.
1347 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1348 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1349 Decoding of SRU "path" database is performed by private function
1350 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1351 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1353 yaz-client: honor base command for SRU. Change when database setting
1354 is applied for SRU and ensure it is kept when a connection is reset.
1355 Change also the way errors are displayed or SRU (decoding of packages).
1357 --- 3.0.50 2009/11/02
1359 Add support for extra request / response data for SRU codecs and GFS.
1360 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1361 for extra data response buffer and length. For the GFS, both request
1362 and response data (XML) is carried in extra_args and extra_response_data
1363 for the search handler. Patch by Ko van der Sloot.
1365 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1366 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1367 10010). This fixes bug #2113.
1369 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1370 cmdfile included a 'quit' command that would result in a memory violation.
1372 --- 3.0.49 2009/10/01
1374 Make a number of functions defined in xmlquery.c static. These have
1375 never been declared in a public header file (yaz/xmlquery.h) and was
1376 made public by mistake.
1378 Improve speed of character conversions (iconv utilities). This makes
1379 conversions from MARC-8 faster.
1381 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1382 unless type desired is "raw". This will prevent type "xml" from
1383 returning ISO2709 .. Which obviously can not be XML parsed.
1385 Fix memory leak in ZOOM that would occur if option apdulog was used
1386 on a re-used connection.
1388 Frontend server logs HTTP requests.
1390 Frontend server now sends Z39.50 close when it times out (sesssion has
1391 been idle for too long). Versions 2.0.30 and earlier also sent close.
1392 But due to a mistake this was disabled in all versions after that, i.e.
1393 the server would just close the socket immediately.
1395 yaz-client emits a better message when receiving an unrecognised
1396 userInformationField.
1398 Skip zero-length subfields when decoding ISO2709. This rare case happens
1399 if a record has two FS characters in a sequence. Without this patch
1400 there would be a reference beyond char array in using_code_len fragments
1403 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1405 --- 3.0.48 2009/08/28
1407 The show command offered by the zoomsh command now takes a 3d optional
1408 parameter type which is what is passed to ZOOM_record. If the type
1409 argument is omitted, "render" is used.
1411 RPN to CQL conv may use USE string attributes (bug #2978).
1413 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1415 --- 3.0.47 2009/07/08
1417 Function yaz_xml2query allows a diagnostic element in the PQF XML
1418 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1419 code and additional info respectively.
1421 The BER BOOLEAN is now the integral type Odr_bool which still happens
1422 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1423 typedef'd to Odr_int. This is still an integral 'int', but it may be
1424 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1425 ASN-1 compiler as well as programs has been updated to use the new types.
1427 --- 3.0.46 2009/06/08
1429 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1430 only the bibliographic record was rendered. For type=opac, an OPAC
1431 record is only returned if it is present.
1433 iconv: small fix for encoding of advancegreek.
1435 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1437 yaz-client: option auto_reconnect=on really reconnects.
1439 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1441 server: avoid null ptr ref for for yaz_poll errors.
1443 build: fix RPM build for RHEL 5.3.
1445 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1447 --- 3.0.45 2009/03/31
1449 Fixed bug #2709: TCP connect returns Invalid argument.
1451 Fixed compilation for mingw.
1453 Honor charset for raw records (ZOOM_record_get).
1455 Fixed use of errno for threaded mode that was seen on Solaris 10.
1457 Fixed argument passing with blanks in value for Windows Service.
1459 Disable YAZ' own log rotate by default (no 1 GB limit).
1460 The variable l_max_size which specifies the log file limit is set to 0
1461 (DISABLED): This is due to the fact that YAZ is most often deployed using
1462 logrotate. Also YAZ can not perform log rotate because of unsufficient
1463 permissions (setuid).
1465 --- 3.0.44 2009/02/17
1467 List supported encodings in man page for yaz-iconv.
1469 Fixed missing SSL libs for --libs output
1471 Re-established OID record syntax application-xml. Nobody should use it
1472 but we don't want to change soname because of this symbol being absent.
1474 --- 3.0.42 2009/02/02
1476 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1478 Added member named_result_sets for init handler struct for the GFS. This
1479 allows a server to disable named result sets.
1481 Removed OID record syntax application-xml.
1483 Added support for rule-based transliterator for ICU wrapper of YAZ.
1485 Fixed bug #1902: yaz-icu XML output.
1487 Make YAZ checks Emacs friendly.
1489 BITSTRING value shows value. Bug #2346.
1491 ISO2709 decoding: skip control characters from indicator data.
1493 Omit sort key by default in yaz-icu's output.
1495 Allow combined single char options (again) for YAZ' options function.
1497 Utility yaz-marcdump got option to display YAZ version (-V).
1499 Allow YAZ to use ICU 3.4.
1501 Added new ICU test case which illustrates removal of diacritics.
1503 --- 3.0.41 2008/12/29
1505 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1507 --- 3.0.40 2008/12/29
1509 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1512 Fixed bug #2352: yaz-marcdump crashes for certain record.
1514 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1516 Added support for Danmarc2 to UTF-8 conversion.
1518 Added support for ISO5426 to UTF-8 conversion.
1520 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1521 implementation version.
1523 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1525 --- 3.0.38 2008/11/10
1527 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1528 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1530 ZOOM C now interprets databaseName option for ZOOM connection as path
1533 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1535 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1537 Dummy Libxml2 types no longer defined in headers of YAZ'.
1539 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1542 --- 3.0.36 2008/09/26
1544 Various ODR chapter fixes.
1546 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1548 Added missing source for Windows compilation, mutex.c.
1550 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1552 For SRU connections in ZOOM all records up to "count" are now fetched.
1554 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1555 in Windows due to bad error handling for Libxml2.
1557 Added facility for sending arbitrary records (ASN.1 any) using
1558 ZOOM C's Extended service update. Patch by Sam Reynolds.
1560 New options for ZOOM C's connection, logapdu which makes ZOOM log
1563 --- 3.0.34 2008/06/18
1565 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1567 --- 3.0.32 2008/06/12
1569 Fixed memory violation that could occur when decoding UTF-8. This bug
1570 was only present in 3.0.30 of YAZ.
1572 --- 3.0.30 2008/06/06
1574 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1575 GNU TLS is used by default (if found).
1577 yaz-ztest returns OPAC records if a client asks for OPAC.
1579 Improved speed of MARC-8 encoding.
1581 Added support for lossy and loss-less MARC-8 encoding.
1583 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1585 Added new Windows Service wrapper (sc).
1587 yaz-client's itemorder command may now send a file.
1589 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1591 Added new function yaz_log_xml_errors.
1593 Allow (but warn) unknown XML attributes in MARCXML parsing.
1595 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1597 The UTF-8 to MARC-8 conversion now uses a different set of characters
1598 for Greek symbols. Bug #2120.
1600 --- 3.0.26 2008/02/21
1602 Added yaz_daemon (daemon.h).
1604 Fixed bug #2068: pkg-config trouble
1606 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1608 --- 3.0.24 2008/01/28
1610 Document --with-xml2 option.
1612 Added OPAC XML XSD (etc/opacxml.xsd).
1614 Allow glob mask for name attribute in retrieval element for the
1615 generic frontend server's retrieval facility.
1617 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1618 except POLLIN/POLLOUT.
1620 Fixed error handling in cs_listen. Bug #2037.
1622 --- 3.0.22 2008/01/20
1624 Fixed version in yaz/yaz-version.h.
1626 Fixed bug #2027: Crash when closing connection.
1628 Changed configure so that ICU support is only enabled if only ICU
1629 and Libxml2 is available (because the ICU chain is XML based).
1631 --- 3.0.20 2008/01/15
1633 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1634 is built. Only this DLL depends on the ICU runtime.
1636 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1637 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1639 Changed license of CCL module to 'Revised BSD'. After consultation with
1640 remaining members of the original EUROPAGATE consortium, we are re-issuing
1641 the CCL module without a separate license. The software was developed by
1642 Index Data as part of a research project. The special license was included
1643 to help feed usage information back to the project consortium to support
1644 project evaluation. At this time, the project consortium has long-since
1645 disbanded, and the majority of the original principals have retired. At the
1646 same time, we have significantly modified the software during the following
1647 years, to the point where very practically no original code remains. To
1648 simplify re-use of the software, we have contacted those members of the
1649 consortium who could be reached, and agreed to re-issue the module as a
1650 proper part of the YAZ package.
1652 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1654 CQL closer to being version 1.2 compliant. CQL also allows free-form
1655 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1658 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1659 bug could make Extended services handling crash in the ZOOM layer. This
1660 bug was only present in YAZ 3.0.18.
1662 --- 3.0.18 2007/12/19
1664 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1667 yaz-marcdump reads and writes collection wrapped records.
1669 Handle OPAC for record conversion module.
1671 Fixes for ICU wrapper.
1673 Allow ICU libs to be controlled with --with-icu .
1675 --- 3.0.16 2007/11/12
1677 Added yaz_poll which is a wrapper for select/poll. When poll is available
1678 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1679 sockets to be in use.
1681 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1682 functionality through an XML based configuration (ICU chain). This system
1683 is useful for search facilities such as Pazpar2 and Zebra that needs to
1684 perform tokenization of indexed material. The ICU code in a separate
1685 library libyaz3_icu.a.
1687 Added HTTP tunnel facility for COMSTACK, bug #1752.
1688 This is a facility that allows a Web proxy, such as squid, to tunnel
1689 Z39.50 traffic. This facility is "transparent" to must applications
1690 using YAZ. It's enabled by using pseudo transport connect: followed by
1691 the proxy address, followed by command, then follwed by he regular
1692 "virtual" addresss. For example,
1693 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1695 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1697 --- 3.0.14 2007/09/21
1699 Fixed bad memory reference in ZOOM_record - cuased by member not being
1700 initialized. This was a problem only in YAZ 3.0.12.
1702 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1703 fields were not removed.
1705 Changed the way C code is generated from codetables.xml. Made a MARC-8
1706 conversion trie for each characterSet section rather than codeTable.
1707 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1708 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1710 --- 3.0.12 2007/09/12
1712 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1713 from ZOOM_record_error).
1715 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1717 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1719 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1721 Better SRW-to-Bib-1 diagnostic mapping.
1723 ZOOM C and yaz-client announces SRU version 1.2 by default.
1725 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1728 Fixed in yaz_sru_decode to allow other version than 1.1.
1730 --- 3.0.10 2007/08/22
1732 Added support for SRU scan for ZOOM.
1734 Added support for the use of the older versions or Extended Service
1735 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1736 set to the version , 1=first, 2=second, 3=third. The third version is
1737 what ZOOM C has used so far. And that, obviously, is the default.
1739 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1740 therefore in Zebra and in SimpleServer-based applications). The new
1741 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1742 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1743 which is passed into the back-end search callback function.
1745 Added support for HTTP Basic authentication in clients: the SRU/W
1746 codec encodes the username/password elements of the PDU structure
1747 appropriately, and these may be set using the "user" and "password"
1748 options in ZOOM-C applications (the same options that are used for
1749 Z39.50 authentication).
1751 --- 3.0.8 2007/06/25
1753 Fixed bug #1208: SSL appears to be broken in ZOOM.
1755 Fixed bug #1206: Libxml2 include path weirdness.
1757 Added oid_name_to_dotstring.
1759 Allow elementSetName to be specified for ZOOM C record update.
1761 Allow waitAction to be specified for ZOOM C based for Extended Services.
1763 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1764 syntax OID. Bug introduced in YAZ 3 series.
1766 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1768 --- 3.0.6 2007/06/06
1770 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1771 directory. yaz-client now reads commands from file given by option -f
1772 if specified; then tries to read .yazclientrc in current directory.
1773 Failing that, it reads .yazclientrc from user's home directory.
1775 Added support for correlationInfo Note and ID for Record Update via
1778 Added yaz-client command querycharset which specifies character set for
1779 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1780 (termListAndStartPoint).
1782 Charset ISO5428:1984 is an alias for ISO5428-1984.
1784 Implemented a way to perform scan in a result set using Z39.50. This
1785 is achieved by attaching the result set name in the characterInfo
1786 (type InternationalString) of OtherInformation in the Scan Request PDU.
1787 The result set is identified in the otherinformation by the new OID:
1788 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1789 This allows for scan in result set and faceted search . Zebra did some
1790 of this in the APT term using attribute type 8 and value being result
1791 set. Using the OtherInformation approach for this is cleaner and easier
1792 to work with in proxies and the like. This facility can be used in
1793 yaz-client using new command setscan which takes a result set as first
1794 argument, start position (APT) as second.
1796 Changed decoding of SRU XML packed records to deal with servers that
1797 have recordData with XML data with multiple root nodes. Also make
1798 comparison for recordPacking case insensitive. Again, one server
1799 returns "XML" where others return "xml".
1801 For SRU responses allow Content-Type application/xml as well as text/xml.
1803 --- 3.0.4 2007/05/21
1805 Fixed bug in character set conversion of BER strings. Bug introduced
1808 --- 3.0.2 2007/05/08
1810 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1812 For OID class, use oid_class consistently.
1814 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1817 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1818 character set for bibliographic information interchange". By Giannis Kosmas.
1820 Added documentation on new OID API.
1822 --- 3.0.0 2007/05/02
1824 Changes to generic frontend server interface: added new member
1825 'query_charset' for bend_initrequest structure. A backend init handler
1826 should set this member to its native character set for query terms.
1827 When defined, the frontend server logic will announce this character set
1828 to a client if the negotiationModel bit is set by the client. All server
1829 implementors are encouraged to specify this. If a backend server does not
1830 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1832 Added CCL utility to remove terms (stop words) from resulting RPN
1833 tree. This is handled by functions with prefix ccl_stop_words_ .
1835 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1836 terms in RPN queries.
1838 Clean-up the CCL API. Moved some internal structures from ccl.h to
1839 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1840 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1841 This is replaced by ccl_parser_find_str which takes a string instead.
1843 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1844 libyaz.la is the core of YAZ except the generic frontend server and
1845 does not depend on POSIX threads anymore. libyaz_server.la is the
1846 generic frontend server facilities and uses POSIX thread functionality
1847 if available. The libyaz.la no longer depends on POSIX threads because
1848 the number of global structures is limited. NMEM no longer re-uses blocks
1849 between threads ; it simply free's memory immediately but allocates in
1850 "large" chunks as usual. We don't expect any performance penalties
1851 because of this. The yaz_log system is still using a global log_level so
1852 caution must be taken when modifying it with yaz_log_init_.. +
1853 yaz_log_mask_str. This, however, should not cause any trouble because
1854 these functions are called during initialization of application code
1855 anyway. `yaz-config --libs server` returns libs for server applications;
1856 `yaz-config --libs` returns libs for non-server applications.
1858 New OID database - with public definitions in oid_db.h. Removed old OID
1859 database including the head oid.h and definitions such as enum oid_value
1860 and struct oident. The new OID database uses the same string names as
1861 before but the 'protocol' is gone. There are now only two representations
1862 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1863 converts from string to OID; functions with prefix yaz_oid_to_string
1864 converts the other way.
1866 Change to emit_term() in CQL-to-PQF query translation: when a term has
1867 the /regexp relation modifier, do not process it for leading and
1868 trailing "^" and "*", which have quite different meanings in regular
1871 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1872 write handlers no longer carries a 'last' parameter. This will make
1873 yaz_iconv flush "less" characters. A flush is performed by call to
1874 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1876 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1877 removed, because function yaz_query_to_wrbuf does the same.
1879 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1880 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1882 Deprecated MARC utility functions removed.
1884 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1887 Branch split: YAZ_2_1_55_branch
1889 --- 2.1.54 2007/03/16
1891 Fix to ZOOM-C so that transparent reconnection is properly handled on
1892 connections that are in asynchronous mode.
1894 Fixed compilation on OpenBSD 4.0.
1896 Large strings in GRS-1 records are now properly displayed in yaz-client.
1898 Added character conversion support for "advancegreek"; based on patch from
1901 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1902 sequence is met. Before the error was not set so it would be unknown.
1904 Adjust yaz-marcdump MARC reader so that it skips until record separator
1907 --- 2.1.52 2007/03/07
1909 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1910 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1911 fd_set structure used as a bitmask for the FDs to be selected on.
1913 Using ACX_PTHREAD macro to check for POSIX threads.
1915 Fixed have-vsnprintf check.
1917 --- 2.1.50 2007/02/23
1919 Fixes for configure on BSD. Bug #900.
1921 Added snprintf/vsnprintf wrappers for systems that don't have
1922 limits (heavens forbid).
1924 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1925 created before all previous tasks were completed and removed from the
1926 task queue, the new task could be removed by a mistake.
1928 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1930 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1932 Fixed bug #832: Problem with MARC/charset in yaz-client.
1934 Fixed bug #668: save command line history for yaz-client.
1936 Fixed bug #830: pkg-config support.
1938 --- 2.1.48 2007/01/23
1940 Extended ZOOM result set options with two options that may be read by
1941 a client: resultSetStatus and presentStatus with values as specified for
1943 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1945 Fixed bug #827: Using SSL fails on Debian etch.
1947 Fixed bug #826: Weird looking chars for set of MARC records.
1949 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1950 that is treated as an ItemOrder with itemRequest being an XML document
1951 external. The value of "doc" is the content.
1953 Extended the GFS search facility. New member of bend_search_rr
1954 'estimated_hit_count' signals that hits is known to be an estmate
1955 (higher or lower than real hit count). New member 'partial_resultset'
1956 signals that the search was partial (hit count is lower or equal than
1957 real hit count). For Z39.50, the information is stored in resultSetStatus
1958 member of SearchResponse APDU. For SRU, the information is signalled
1959 via SRU diagnostic 59: "Result set created with valid partial results
1962 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1964 --- 2.1.46 2007/01/13
1966 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1968 Added ZOOM_connection_peek_event.
1970 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1971 the following new functions:
1972 ZOOM_event_nonblock, ZOOM_connection_process,
1973 ZOOM_connection_get_{socket,mask,timeout},
1974 ZOOM_connection_fire_event_{timeout,socket}.
1975 The existing blocking event handler, ZOOM_event, is a wrapper for the
1976 + blocking ZOOM_event_sys_{poll,select}.
1978 Implemented function ccl_xml_config which parses XML version of CCL
1979 configuration (bug #798).
1981 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1983 Added timings utility (yaz/timing.h)
1985 --- 2.1.44 2007/01/03
1987 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1990 Fixed bug #779: Rotation of apdu.log fails.
1992 Fixed for character set conversions:
1993 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1994 Honor G1 set in MARC-8 decoding.
1996 --- 2.1.42 2006/12/17
1998 Fixed bug #775: char conversion does not handle Alternative UTF-8
2001 Implemented function yaz_marc_read_line which parses MARC line format
2002 records. There is a wealth of formats out there. So far, this function
2003 reads line records produced by yaz_marc_write_line.
2005 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2006 more generic and easier to remember(!) options: -i format and -o format
2007 which specifies input format and output format respectively - where
2008 format is one of "marc", "marcxml", "line", "marcxchange".
2010 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2011 does not print anything except warnings for records.
2013 For yaz-marcdump, added support for MARC split into files (-s) with a given
2016 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2017 spec, at http://www.loc.gov/standards/sru/record-update/
2018 This has changed the binary layout of the following structs:
2019 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2020 bend_update_rr . Patch by Ko van der Sloot.
2022 Added GFS utility function bend_assoc_is_alive which returns 1 if
2023 association is still alive (client is connected); 0 otherwise (client
2024 closed connection). This allows busy servers to stop working for
2027 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2028 been a separate piece of software. This version of ziffy has been modified
2029 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2031 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2033 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2034 Client code may now interrogate options such as "init_opt_sort" to
2035 find out whether the server claims to support various options.
2037 --- 2.1.40 2006/11/27
2039 Added utilities yaz_{set,get}_esn to set/get element set name from
2042 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2043 of YAZ and has been so since YAZ 2.1.10.
2045 Implemented ZOOM_record_error which returns error information for
2046 record (surrogate diagnostic).
2048 --- 2.1.38 2006/10/31
2050 Updates for SRU Update by Ko van der Sloot:
2051 1. Changed name from "operation" to "action"
2052 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2053 versions in the code, marked as 'backward compatible'.
2054 3. Added diagnostics for SRU Update.
2056 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2058 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2060 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2062 For GFS, fixed problem with SRU diagnostic 'First record position out of
2063 range' being issued for 0 hits.
2065 zoomtst10 part of Windows Build.
2067 --- 2.1.36 2006/10/13
2069 Implemented yaz_filepath_comp which splits a path into file path
2070 components (required by Zebra 2.0.3+).
2072 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2073 BSD inspired license until now so this should not have any real impact on
2074 anybody. See http://www.opensource.org/licenses/bsd-license.php
2076 Fixed bug #687: Missing log lines.
2078 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2081 Fixed bug #689: SRU diagnostics to be added.
2083 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2084 whether a connection is idle (no more work do do).
2086 --- 2.1.34 2006/10/04
2088 Change type of optval from long to int for invocation of setsockopt with
2089 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2091 Added support for specifying the max log file size for the Generic
2092 Frontend Server. The size is given with option -r.
2094 --- 2.1.32 2006/09/21
2096 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2098 --- 2.1.30 2006/09/17
2100 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2103 Fixed bug in Generic Frontend Server that could cause a server to stop
2104 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2106 For the generic frontend server, the maximum record size is used as maximum
2107 size of incoming packages (SRU + Z39.50). The value until was previously
2108 only used in Z39.50 Init negotiation and, later, in a session controlled
2109 sizes of records returned. This is controlled using -k option. It can be
2110 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2112 --- 2.1.28 2006/09/04
2114 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2117 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2119 New option for yaz-marcdump -lpos=value which allows setting a portion
2120 of MARC header to a certain value.
2122 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2124 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2125 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2127 --- 2.1.26 2006/08/15
2129 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2132 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2134 --- 2.1.24 2006/08/08
2136 Fixed MARC ISO2709 encoding routines to deal with character set
2139 Minor changes to GFS logging. Database included in search request log
2142 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2143 cached/multiple records.
2145 Shared libraries are built by default on Unix+configure.
2147 Changed cql2pqf transformation to use a different evaluation order. The
2148 new order is: always, relation, structure, position, truncation, index
2149 and relationModifier. Old order was: always, relation, relationModifier,
2150 structure, index, position, truncation. Note that the the latter ones
2151 override former ones for identical attributes.. The new scheme means that
2152 it is possible to override any existing attribute with a relationModifier.
2153 And also that it is possible to override everything for the index rule
2154 (except the ones listed in relationModifier). No order is perfect but this
2155 one, we believe, covers more real cases.. The "always" should have been
2156 called "default", since the attributes there can be overridden with all
2159 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2160 compilation phase, but also for yaz-config --cflags output. This allows
2161 us to have public headers with Libxml2 stuff in them . It should also,
2162 eventually, make Libxml2 checks redundant in packages using YAZ, such
2165 --- 2.1.22 2006/06/15
2167 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2168 stored in uri, message and details.. Previously diagnostics were stored
2169 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2170 compatibility.. but he's probably the only one affected, so.
2172 Added support for CCL, compiled on the client side, in ZOOM-C. This
2173 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2174 input; the resulting query objects can be used for for searching with
2175 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2177 YAZ' configure searches for OpenSSL by default.
2179 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2180 SL_CTX_use_certificate_file. See
2181 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2182 for more info. Thanks to Ko van der Sloot.
2184 --- 2.1.20 2006/06/02
2186 Bug #600: SRU GET, POST support for yaz-client. Introduced
2187 command 'sru' which selects method SOAP/GET/POST.
2189 Allow missingValueAction to be specified for the sortspec string -
2190 function yaz_sort_spec. By default, the missing value action is null.
2191 Use ! to specify "abort". Use = followed by stringvalue to specify default
2194 Ensured that Present-handler (if defined) is called in GFS before any call to
2195 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2196 searchRetrieve requests.
2198 Documentation for YAZ is now based on the Docbook XML/XSLT using
2199 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2200 is no longer depending on jade/openjade or docbook-to-man scripts.
2201 PDF is no longer part of the distribution - but can optionally be
2202 made using DSSSL/jadetex or FOP.
2204 Added retrieval handling support in Generic Frontend Server to support
2205 conversion between MARC/XML as well as XSLTtransforms. See
2206 etc/yazgfs.xml for an example.
2208 Added Authentication support to Generic Frontend Server in SRU
2209 mode. Authentication using HTTP Basic is supported, as is the use
2210 of 'x-username' and 'x-password' parameters in the request itself.
2212 Added support for a new character set MARC8s identical to MARC8 except
2213 that it converts combined characters to single Unicode characters in the
2214 Latin-1 range (when possible).
2216 --- 2.1.18 2006/04/24
2218 ASN.1 compiler 0.4: generates brief Doxygen file header for
2219 generated .h/.c files.
2221 Utility yaz_iconv now supports conversion to MARC-8.
2223 New facilities for the MARC module. The reading - and writing of
2224 content are separate methods for the yaz_marc_t handle. The following
2225 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2226 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2227 format). Write functions have prefix yaz_marc_write_.. The existing
2228 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2229 available. Removed support for OAI-MARC and simplexml (not the
2230 simplexml from PHP5).
2232 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2233 to be returned for this connection.
2235 --- 2.1.16 2006/03/31
2237 Allow multiple languages and charsets to be specified with
2238 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2239 negcharset iso-8859-1,utf-8
2241 Translation of proximity nodes from CQL into PQF now works.
2243 Moved to automake 1.8, 1.9.
2245 Added function yaz_log_set_handler which allows a log handler to be
2246 installed. This handler will be called for all log messages. Output
2247 to file is also produced; but that can be disabled by passing NULL
2248 fname to yaz_log_init_file.
2250 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2252 For SRW (including GFS), accept application/soap+xml as content-type
2255 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2256 produces NO stylesheet reference even if a default stylesheet is specified
2259 --- 2.1.14 2006/03/14
2261 Updated Windows package to include yazd.dll + yazd.lib for the
2262 Development component.
2264 If the environment variable YAZ_LOG is set, then it is used as a
2265 string indicating the default level of logging to use if not
2266 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2267 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2268 used as before. So, for example, to omit warnings from YAZ logging,
2269 export YAZ_LOG=-warn
2271 cql_transform() now map structure and other attributes before indexes,
2272 so that index-specific structures and other attributes can override
2273 defaults. So now a combination of mapping specifications such as:
2275 index.dc.date = 1=date-modified 4=5
2276 does the right thing.
2278 cql_transform() now also respects the "always" mapping specification,
2279 which establishes an initial set of attributes to be used for all
2280 terms except where overridden by more specific attributes associated
2281 with the index, relation or modifier.
2283 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2284 which mode to use; one of "post", "get" or "soap" (SRW, default).
2286 Fixes for yaz_iconv routines: changed trie-based character set conversions
2287 to use only non-negative values for bit fields due to Sun's C compiler not
2288 supporting negative values.
2290 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2291 sequences where not read correctly. Fix by Rustam Usmanov.
2293 Updated win/makefile to use options, settings which makes things
2294 compile with VS C 2005.
2296 --- 2.1.12 2006/02/01
2298 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2300 In ZOOM socket code, use select instead of poll on MacOSX.
2302 ZOOM-C now support client-side compilation of CQL into RPN that is
2303 sent to the server, enabling CQL to be used against all Z39.50
2304 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2305 ZOOM_query object, and submit it using ZOOM_connection_search().
2306 The CQL-to-RPN translation uses a configuration file, the name of
2307 which must be specified in the Connection's "cqlfile" option.
2309 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2310 function, which takes as its start-term parameter a ZOOM_query object
2311 (which may have had either CQL or RPN set into it).
2314 --- 2.1.10 2005/11/29
2316 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2317 GFS to support this as well. Backend handler, bend_srw_update, does the
2318 update work. Code contributed by Ko van der Sloot.
2320 Allow retrieval of Search Result-1 information in ZOOM by the use of
2321 options that are attached to a result set. ZOOM documentation updated
2324 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2325 UTF-8 conversion. Patch by Raj Patel.
2327 Added option -m to GFS to control formatting of timestamps in log file.
2329 Added 'exit' as synonym for 'quit' in yaz-client
2331 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2332 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2333 for the new members. Patch by Ko van der Sloot.
2335 Added support for SRU POST. It is supported for content-type
2336 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2338 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2339 Instead make the library libyaz.la multi-threaded. Threading as a whole
2340 can still be disabled by configure option --disable-threads. Previosly,
2341 with older GLIBCs there were problems with MT libs under Apache. This
2342 has now been fixed a long time ago.
2344 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2347 CQL module modified to be case insensitive for relations/indexes/operations.
2349 Fixed bug in CQL transform code: incorrect value relationModifieder
2352 Added 'show all' command for yaz-client which retrieves all results
2355 Added new yaz-client, xmles, which takes a (private) OID and
2356 a document to be sent as an extended service request.
2358 Describe new yaz-client commands wait_response and set_auto_wait.
2360 Increase TCP/IP listener backlog from 3 (which I am guessing was
2361 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2362 that the socket will queue as many incoming connections as it's able
2363 to handle ongoing connections. In other words, it will never now
2364 refuse a connection that it would be able to handle merely because
2365 it's not got around to accepting() enough of the pending connections
2366 yet. This is the behaviour anyway under Linux, where the listen()
2367 argument is ignored; but not under BSD and on systems such as
2368 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2369 YAZ-based servers should now be uniform across operating systems in
2372 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2373 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2374 This allows yaz-marcdump to read large MARC batches (>2 GB).
2376 Modified all YAZ source files - except the source which is auto-generated
2377 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2380 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2381 corresponding to the existing *_setl() function. These allow option
2382 values containing arbitrary valuues.
2384 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2385 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2386 except that it returns an indicator of whether or not the sort
2387 criterion was accepted (0 for OK, -1 for invalid).
2389 --- 2.1.8 2005/06/07
2391 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2392 MARC output rather than returning "new" buffer.
2394 yaz-client warns about unknown init options.
2396 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2398 --- 2.1.6 2005/05/24
2400 Added support for SRW sort in Generic Frontend Server. Patch
2401 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2402 sortKeys - or NULL if none is provided.
2404 Fixed bug #307: It was impossible to specify indefinite/no timeout
2405 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2408 Added support for multiple languages and charsets to be specified in
2409 ZOOM. Each charset/language is separated by a blank. If negotiation is
2410 in effect in init-response, Option
2411 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2412 Code based on patch by Vasiliy Osadchuk.
2414 Fixed bug #306: infinite recursion that occurred when calling
2415 yaz_log_level_init as the first call (before other log level or
2418 Fixed bug in scan handling in front end server: if preferred-Position-In-
2419 Response was non-present, a NULL pointer referece was performed.
2421 --- 2.1.4 2005/04/26
2423 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2424 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2425 now defined for all those error codes. So instead of putting 109 in
2426 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2427 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2429 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2432 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2434 Program yaz-client now exits and produces an error message if multiple
2435 Z39.50 servers are specified on the command line (none or one allowed
2438 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2441 --- 2.1.2 2005/03/16
2443 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2445 Fixed bug #272: Preserve spacing for CCL terms.
2447 --- 2.1.0 2005/03/14
2449 Added support for virtual hosts and multiple backend servers for
2450 the YAZ frontend server. The configution is XML based and
2451 support specificition of CQL to RPN mappings and explain information.
2452 See section "Virtual Hosts" in the YAZ manual.
2454 Extended OPAC display utility. OPAC display utility renders
2455 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2456 to supplement yaz_marc_decode_wrbuf.
2458 Fixed a bug in MARC decoder that could caused it to crash for some
2459 invalid MARC records. More diagnostics and warnings where added in
2460 XML output (warnings, etc are stored in comments).
2462 --- 2.0.34 2005/02/08
2464 Fixes for UNIX domain sockets. Bug #261.
2466 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2468 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2469 Added yaz_marc_subfield_str which defines subfield lead string which is
2470 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2471 yaz_marc_endline_str which defines end of fields string used in
2472 YAZ_MARC_LINE format. Default string is newline.
2474 Experimental support for MarcXChange. This format can be produced
2475 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2476 http://www.bs.dk/standards/MarcXchange.xsd
2478 Added yaz-client commands scansize that sets maximum number of
2479 entries to be returned by scan.
2481 --- 2.0.32 2005/01/11
2483 Added support for SRW scan in yaz-client and Generic Frontend Server.
2485 * Added whereInList member to SRW Scan Term.
2487 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2489 Fixed NMEM system to return aligned blocks on the smallest boundaries
2490 that are suitably aligned for all possible types on the particular
2491 architecture YAZ is being built for.
2493 --- 2.0.30 2005/01/04
2495 Fixed numerious warnings that was issued with newer versions of GCC.
2497 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2498 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2501 Make YAZ Generic Frontend Server slightly faster.
2503 Enhance (and reduce) logging for Generic Frontend Server.
2505 Revert YAZ log system so that it flushes every write operation
2506 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2508 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2509 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2510 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2511 will effectively disable old definitions.
2513 --- 2.0.28 2004/11/09
2515 Added yaz_log_time_format which specifies log format using
2518 Added yaz_log_module_level which returns mask for a module. Value
2519 is non-zero mask a if module is enabled; zero if disabled.
2521 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2522 in include/yaz/cql.h.
2524 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2526 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2528 Fixed bug #172: RPM builds does not enable SSL.
2530 Doxyfile.in part of dist. Doxyfile generated by configure.
2532 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2533 are given and the corresponding component does not exist.
2535 Extend CCL documentation in YAZ reference. Describe r=r.
2537 --- 2.0.26 2004/10/01
2539 Fixed MARC->MARCXML conversion to properly deal with
2540 fields, subfields, indicators having non-ASCII characters.
2542 Fixed MARC->MARCXML conversion so that ASCII control characters
2543 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2546 Added YAZ GFS support for conversion from Z39.50 surrogate
2547 diagnostics to SRW surrogate diagnostics.
2549 Bug fix: YAZ GFS did not return schema in explainResponse.
2551 --- 2.0.25 2004/09/30
2553 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2554 now converts recordSchema to elementSetName as well as schema URI.
2556 Fixed bug in COMSTACK that prevented HTTP request packages from being
2559 --- 2.0.24 2004/09/29
2561 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2562 does not require white-space before and after the dash in a range, e.g.
2563 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2566 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2567 due to new GCC removing "redundant" code.
2569 Added yaz-client commands scanpos and scanstep that sets preferred
2570 position and step-size for scan.
2572 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2574 Added CCL utility ccl_qual_buf which parses one or more CCL
2575 spec lines in a buffer.
2577 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2578 of name and value - ignoring empty lines and comments.
2580 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2582 Added odr_get_element_path which returns current element path for an
2583 ODR handle. This utility is useful in error handling or user-defined
2586 Added ODR_PRINT utility odr_set_stream which is is a more generic
2587 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2588 to a write function and pointer to close function. The close function - if
2589 non-NULL - will be called during odr_destroy.
2591 Fixed bug in CCL parser where truncation char was not removed from
2592 right side when truncation=both was in effect.
2594 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2597 --- 2.0.23 2004/08/11
2599 Fix buffer overrun in CQL parser when dealing with proximity (%).
2601 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2602 to UTF-8/UCS conversion is now only based on codetables.xml.
2604 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2606 --- 2.0.22 2004/08/06
2608 Add support for more "commit changes" in ZOOM (uses Extended Services).
2610 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2613 Yet another small fix for configure of SSL.
2615 --- 2.0.21 2004/05/14
2617 Fix SSL libs for configure when --with-openssl=DIR is given.
2619 --- 2.0.20 2004/05/10
2621 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2623 SSL comstack now uses yaz.pem certificate file on server side
2624 by default. Certificate filename can be configured by calling
2625 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2627 Fix bug regarding multiple calls to ZOOM_connection_connect.
2629 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2631 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2632 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2634 ZOOM now allows inspection of X509 peer certificate for verification.
2635 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2637 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2638 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2639 as "modular" but it simplifies things.
2641 Added cs_get_peer_certificate to that returns peer X509 PEM.
2643 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2644 NULL if SSL is unavailable.
2646 Documentation about MARC decoding tools.
2648 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2650 --- 2.0.19 2004/03/30
2652 Rename CHANGELOG to NEWS to follow GNU style packing.
2654 Fix bug with missing initialization of member in init_diagnostics.
2655 This bug affects threaded version of GFS server.
2657 --- 2.0.18 2004/03/20
2659 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2662 Ensure zlib.dll is packed with Windows install.
2664 --- 2.0.17 2004/03/17
2666 Fix encoding of xsd:string to use text instead of CDATA.
2668 Fix endless loop in CQL parser with unbalanced ".
2670 Use a more compact way to store MARC-8 conversion tables.
2672 --- 2.0.16 2004/03/16 Debian only
2674 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2677 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2682 --- 2.0.15 2004/03/01
2684 Another fix for decoding of XML packed records.
2686 --- 2.0.14 2004/02/25
2688 Fixes for Chunked encoding. White space not ignored after length spec.
2690 Update NS and use default NS for SRW diagnostic elements.
2692 --- 2.0.13 2004/02/23
2694 Implement ZOOM_resultset_cache_reset which resets record cache.
2696 Implement ZOOM_resultset_sort which sorts a result set.
2698 Implement chunked HTTP transfer.
2700 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2702 --- 2.0.12 2004/02/16
2704 Added member 'schema' to bend_explain_rr structure so that backend
2705 can specify explain record identifier. Defaults to Zeerex 2.0.
2707 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2709 --- 2.0.11 2004/02/16
2711 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2714 Added init command for yaz-client which sends "extra" init request.
2716 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2717 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2719 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2721 Make ZOOM error code for "invalid query".
2723 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2725 --- 2.0.10 2004/02/05
2727 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2730 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2732 Added option -p <file> to make Generic Frontend Server to write PID file.
2734 Added option -D to put Generic Frontend Server in background on its own.
2736 Make ZOOM C recognize option "password". If unset, "pass" is used
2737 (for backwards compatibility).
2739 Fixed a bug in Generic Frontend Server that could make it crash if a
2740 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2743 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2744 Must be issued before open, in order to be in effect.
2746 --- 2.0.9-6 2004/01/12 Debian/Windows
2748 Make the SRU server more picky WRT unknown params, etc.
2750 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2752 New YAZ client command, options, that sets Z39.50 options.
2754 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2755 options from a string of tokens (one token for each option bit).
2757 Update SRW diagnostic code messages.
2759 --- 2.0.9-5 2004/01/07 Debian/Windows
2761 Handle user defined stylesheet for SRW/SRU.
2763 --- 2.0.9-4 2004/01/06 Debian/Windows
2765 Fix bug in decoding of Content-Length.
2767 --- 2.0.9-3 2004/01/06 Debian/Windows
2769 Fix a bug with decoding of XML packed records.
2771 --- 2.0.9-2 2004/01/05 Debian only
2773 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2775 Fix bug in SRW/SRU diagnostics decoding.
2777 --- 2.0.9 2004/01/05
2779 Fixed bug in Generic Frontend Server which could drop records exceeding
2780 preferred message size. Reported and fixed by Irina Dijour.
2782 Fixed calculation of package size for structured records in Generic
2783 Frontend Server. Reported and fixed by Irina Dijour.
2785 Fixed namespace for SRW/SRU diagnostics.
2787 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2789 --- 2.0.8 2003/12/22
2791 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2792 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2795 CQL changes to reflect recent changes to the specification:
2796 * Documentation talks about context sets instead of index sets.
2797 * Documentation talks about indexes instead of qualifiers.
2798 * The CQL-to-PQF transformer's configuration file now uses
2799 "index.set.name = <attributes>" instead of the old form
2800 "qualifier.set.name = <attributes>". (Both forms are still
2801 understood but the latter is deprecated.)
2802 * CQL terms with no explicit index specified are now interpreted as
2803 cql.serverChoice instead of srw.serverChoice (which of course
2804 behaves exactly the same.)
2806 --- 2.0.7 2003/12/16
2808 MARC conversion can now generate ISO2709 output in another
2809 character set. yaz-marcdump uses this facility if you invoke it
2812 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2813 functions from there can be used from C++.
2815 --- 2.0.6 2003/12/04
2817 Frontend server now transfers memory from decoded packages to stream
2820 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2821 references to show up.
2823 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2824 the ZOOM Abstract API. The older names for the same options are still
2825 also supported for the benefit of old applications.
2827 ZOOM-C supports "implementationId" and "implementationVersion" options
2828 to go along with "implementationName". These allow the user code to
2829 specify identification strings to be sent to servers.
2830 Add OID for the new ExtLite attribute set.
2832 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2833 as requested/supplid by Ere Maijala <ere@atp.fi>
2835 For generic frontend server, reverse the order of
2836 "toolkit-supplied / application-supplied" strings sent as implementationId,
2837 Name and Version. Also, remove the spaces around the slash. This brings
2838 the GFS in line with the behaviour of ZOOM-C on the client side.
2840 Add function ZOOM_scanset_display_term.
2842 yaz-client shows scan displayTerm if present.
2844 Utility yaz-iconv is now installed by default along with the man page
2847 Extend configure check for OpenSSL to use pkg-config where available (such
2850 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2851 server to specify uid/gid/mask for socket using the format
2852 unix:[user=uid,][group=gid,][umask=mask,]file=path
2853 If file= is omitted the existing format is assumed, e.g.
2855 in which case the mask is 0666 (rw for everybody).
2857 Major restructure of YAZ source. All source in libyaz is in src directory.
2858 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2859 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2861 Added man page for utility yaz-marcdump (used to be called marcdump).
2862 yaz-marcdump is installed by 'make install'.
2864 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2865 of incoming package failed.
2867 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2869 Change prototype of odr_perror: add const to message string.
2871 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2873 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2874 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2875 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2876 DNS lookup. There should not be any compatibility problems with this
2877 assuming that blocking=1 or 0 is used.
2879 Fix bad reference in UNIX comstack in function cs_addrstr.
2881 Fix for compilation on AIX.
2883 The generic front-end server (server/seshigh.c) now supports returning
2884 Init diagnostics to the client in User-information-field, in
2885 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2888 --- 2.0.4 2003/09/04
2890 Allow any CQL relation (not just all,any,exact,scr).
2892 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2893 that features the same UI.
2895 Implemented command update0 in YAZ client which is equivalent to
2896 update but uses old of Ext Update ASN.1.
2898 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2899 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2900 Previously no OID was used for this info.
2902 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2903 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2904 returns 'malformed search term' otherwise.
2906 SortResponse member resultCount now set to NULL in sort handler of
2909 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2912 Add three new utility functions for translating OIDs between various
2913 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2914 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2915 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2916 char *oid_to_dotstring(const int *oid, char *oidbuf);
2917 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2919 Reverted modifications for ES Update definition for z_IU0Update
2920 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2921 is back to YAZ 2.0.2.
2923 String value attributes for CCL parser.
2925 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2926 which their FirstSearch server returns in Init responses, sometimes
2927 carrying useful diagnostic information when Init fails. This has the
2928 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2929 "z39.50/oclcui.asn", where its definition is somewhat different from
2930 what OCLC document on their web-site, as required to interoperate with
2933 Support for anonymous authentication in yaz-client. Use the command
2936 * Fix the OID of the Index Data-local "admin" Extended Service from
2937 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2938 the 1000, which indicates a locally-defined OID, was a mistake.
2940 --- 2.0.3 2003/06/20
2942 Fix CCL directive @case handling so that it affects string match for
2943 both CCL keywords and qualifiers.
2945 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2946 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2947 Decoder has been updated with ASN.1 changes as listed in
2948 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2949 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2950 z_IUUpdate, remains unchanged.
2952 ZOOM_record_get may now return a record in a specific character set.
2953 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2954 "from" is the character set of record as returned by target. "to" is
2955 the character set to be returned. If omitted, "to" is UTF-8.
2957 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2959 New ODR utility, odr_getelement, which returns name of element for
2960 which encoding/decoding failed.
2962 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2963 in cases where a required element was omitted.
2965 Bug fix: some MARC8 sequences were not converted.
2967 New ZOOM option "step" which specifies number of records to be
2968 retrieved in one chunk. Used in conjunction with "start" and "count".
2970 SRW support for yaz-client. Use scheme http: to use it, e.g.
2973 yaz-client no longer does (un)intelligent character set conversions
2974 by default. Can be enabled with charset and marc_charset commands.
2976 xmalloc trace fix for 64-bit systems such as DEC alpha.
2978 Solaris 2.6 compile fix.
2980 New function, cql_strerror() translates SRW error codes, as returned
2981 by cql_transform_error(), into human-readable English strings. Used
2982 in yaz-client diagnostics when appropriate.
2984 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2985 converts it into a type-1 query which is sent to the server. This
2986 makes CQL available for use with all Z-servers, as opposed to the tiny
2987 minority that can handle CQL queries themselves.
2989 --- 2.0.2 2003/04/28
2991 New Debian package layout similar to the Redhat Package layout.
2993 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2994 and search result respectively.
2996 --- 2.0.1 2003/04/25
2998 Redhat package is now several packages: libyaz (runtime libraries),
2999 libyaz-devel (development and documentation, and yaz (utility programs).
3000 Package spec file by Morten Bogeskov.
3002 New member 'schema' in struct bend_fetch_rr which the name of requested
3003 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3004 handler MAY set this to reflect the schema of the returned record.
3006 New member 'display_term' in struct scan_entry. GFS now sets member entries
3007 and allocates scan entries to be filled by user scan handler. In previous
3008 version, entries member was allocated by the scan handler. That still works,
3009 but the GFS will ignore member display_term - assuming it was NOT set by
3010 the handler. The fact that the GFS now allocates the entries both allows
3011 for new members and makes a scan handler easier to write.
3013 Fix CQL lex buffer overflow.
3015 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3016 SRU default recordPacking is string.
3018 SRU protocol support for frontend server.
3020 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3022 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3024 Added scan for the ZOOM shell (zoomsh).
3028 * String Identifers for Schemas (Amendment 5).
3029 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3030 Old definition for schema
3031 Odr_oid *schema; /* OPT */
3036 Z_InternationalString *uri;
3037 #define Z_Schema_oid 1
3038 #define Z_Schema_uri 2
3041 * resultCount parameter to Sort Response (Amendment 1).
3042 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3044 Support for SRW 1.0 over HTTP. This is an optional feature and
3045 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3048 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3049 on the same port. SRW SearchRetrieveRequests are mapped
3050 to bend_init,bend_search,bend_fetch,bend_close.
3052 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3054 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3055 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3057 ZOOM connections are SRW based if schem http is used for hostname
3058 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3059 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3061 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3062 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3063 distance=n, order=true/false, relation=le, prox unit=word. If
3064 n is omitted, distance 1 is used.
3066 Fixed problem with C compiler include path in wrong order.
3068 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3069 on Solaris. Patch from Ko van der Sloot.
3071 New MARC decode API. All new functions operate on a yaz_marc_t
3072 handle. The most important new functions are: yaz_marc_create,
3073 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3074 decode and destroy respectively. Decoder can produce formats
3075 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3076 include/yaz/marcdisp.h.
3078 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3079 to UTF-8, UCS-32, wchar_t or Latin-1.
3081 * Prototypes for yaz_iconv_-functions moved to separate header
3082 include/yaz/yaz-iconv.h.
3084 Make a few private functions 'static' in unix.c. This prevents
3085 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3087 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3088 are set when Init Response is received.
3090 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3091 but returns diagnostic set as well.
3093 New function yaz_strerror which is a portable wrapper for
3094 strerror/strerror_r/GetLastMessage.
3096 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3097 is returned for MARC. If type is "oai", then OAI MARC is returned.
3099 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3102 --- 1.9.2 2002/11/26
3104 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3106 Fix bad race conditions on SIGTERM and terminate gracefully in
3109 Move retrieval (data1) module to Zebra since nobody seems to be
3112 Add GRS-1 render for ZOOM using same format as yaz-client.
3114 --- 1.9.1 2002/10/05
3116 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3118 Fix broken ESpec handling in data1 module.
3120 SGML reader parses comments and makes them part of the data1 tree.
3122 Added several type casts so that YAZ compiles as C++ code.
3124 ZOOM didn't handle PDU encoding failures properly.
3126 Added more Bib-1 diagnostics (approved extensions).
3128 GNU configure: better check for iconv.
3130 More portable use of accept, getpeername. Check for socklen_t. Use
3131 int/size_t if socklen_t is not defined.
3135 PQF parser rejects bad queries - including those with extra
3136 characters in them. PQF parser used to silently ignore that.
3137 Cleaner API for PQF added, which allows you to get detailed
3138 error information for bad queries (see yaz/pquery.h).
3140 Fixed bug in ZOOM_record_get for type "database".
3142 Implemented mini iconv library supporting conversions between
3143 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3145 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3147 --- 1.8.9 2002/08/20
3149 Fixed ZOOM C record cache so that preferredRecordSyntax and
3150 elementSetName is used to check for already fetched records.
3152 --- 1.8.8 2002/08/02
3154 Added three members in bend_initrequest structure to facilitate
3155 character set negotiation.
3157 Fixed a bug in frontend server that could cause indefinite
3158 loops under rare conditions.
3160 Revised character set utilities (charneg.h) so that encoding
3161 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3163 For PQF, directive @term <type> sets term type for Scan/Search.
3164 Here <type> is general, string, numeric, null. The term type
3165 is inherited - just like @attr.
3167 New call odr_set_charset that sets character set conversion for
3168 international-strings on a ODR stream. Prototype is:
3169 int odr_set_charset(ODR o, const char *to, const char *from);
3170 The InternationalString is still represented as C string in YAZ
3171 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3172 won't). On the protocol level, you can use any encoding.
3174 Support for UNIX sockets in ZOOM.
3176 Solaris recv sometimes returns errno == ENOENT. It is treated as
3177 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3179 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3180 both client and server. Code by Morten Bogeskov.
3182 --- 1.8.7 2002/05/22
3184 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3185 that they can be used directly from Visual Basic. You must recompile
3186 your windows APP if you're using ZOOM.
3188 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3189 Commands "lang" and "charset" sets language and character set respectively.
3190 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3191 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3193 Attributes from multiple CCL fields may be OR'ed rather than merged
3194 using directive "@field or". Fields are still merged by default -
3195 equivalent to "@field merge".
3197 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3200 Fixed bug in zget for parameter ExtendedServicesResponse.
3204 --- 1.8.6 2002/03/25
3206 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3208 Client displays USR.1:SearchResult-1 (hits per term).
3210 Additional Search Info for search in Generic Frontend Server.
3212 Fixed CCL parsing of "field=s".
3214 WIN32 installer - using the excellent NSIS software from nullsoft.
3216 Fixed CCL parsing of "field = - <number>".
3218 Added function yaz_marc_decode that decodes MARC for line mode
3219 display or XML (similar to that used by JZKit).
3221 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3222 Z39.50. But ISO/ILL was, however.
3224 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3225 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3227 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3228 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3230 --- 1.8.5 2002/02/03
3232 New YAZ client features: Command completion and new commands:
3233 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3234 Code provided by Jacob Poulsen.
3236 New call oid_trav, that visits all registered OIDs via callback.
3238 Function ZOOM_record_get now returns const char pointer rather than
3239 void pointer. It saves a lot of type casts.
3241 For YAZ client, command "auth" now allows you to set authentication
3242 in IdPass style. It is enabled when three tokens are given - order
3243 is user, group and password.
3245 Fix memory leaks in MARC record handling for ZOOM.
3247 New option for YAZ client, -k <kilobytes> that sets
3248 maximum record size. Similar to -k option for generic frontend
3249 server and yaz-ztest.
3251 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3253 Prefix query parser reports "fail" when bad attribute set is given.
3255 Fix in MARC decoder. Proximity logging. Fix for attribute set
3256 in scan handler for server. Patches by Shigeru Ishida.
3258 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3261 Configure option --with-openssl=<dir> now works when a directory is
3262 specified. Patch provided by Morten Bogeskov.
3264 New option for YAZ client, -u <auth>, that sets authentication.
3266 ZOOM fix: error information was sometimes "missing", since error
3267 was cleared/reset too when it shouldn't.
3269 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3271 --- 1.8.4 2002/01/04
3273 Scan for ZOOM API. New object ZOOM_scanset. New functions
3274 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3275 ZOOM_scanset_destroy.
3277 New ZOOM function, ZOOM_connection_last_event, that returns type
3278 of last event (such as "receive data", "send data", "apdu received",
3281 New ZOOM option, schema, that specifies schema for retrieval.
3283 New CCL feature. Qualifiers can be aliases for one or more
3284 other qualifiers (if more than one is given, OR is used).
3286 ZOOM uses named result sets if target supports it.
3288 Two new YAZ client commands: . (dot, which sources a script of YAZ
3289 client commands), and ! (to execute shell command.). Implemented
3292 Working on Debian packages.
3294 --- 1.8.3 2001/11/19
3296 YAZ client enables named result sets only if target supports it.
3298 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3300 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3301 with key="host" to get same result.
3303 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3304 Function Z3950_resultset_record(s) returns references to records
3305 "owned" by resultset. To become owner use Z3950_record_clone.
3307 Function z_ext_record handles Extended Services. Thanks to
3310 --- 1.8.2 2001/11/12
3312 CCL Parser fix: ignore token comma when dealing with and-lists.
3314 Documentation updates for COMSTACK.
3316 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3317 Changed prototype Z3950_records. For some functions, int parameters
3318 were changed to size_t.
3320 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3323 New MARC decode/display function, marc_display_exl, which properly rejects
3324 non-ISO2709 records. YAZ client uses it.
3326 --- 1.8.1 2001/10/29
3328 Fix bug: local attribute set wasn't set correctly in PQF strings.
3332 * Old Z39.50 codecs no longer supported.
3334 Added ZOOM C binding. See http://zoom.z3950.org/
3336 Renamed states for COMSTACKs to avoid confusion with events.
3338 Implemented cs_look and proper cs_rcvconnect.
3340 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3342 Configure detects POSIX threads on OpenBSD.
3344 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3345 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3347 When error is returned from present handler, non-surrogate diagnostic
3348 is returned in present response (and fetch handler is no longer called).
3350 * Minor adjustments to pquery parser (PQF). Token characters may be
3351 escaped by using backslash (C-style).
3353 PQF parser allows string attribute values to be specified. For @attr,
3354 non-numeric characters after the equal-sign are treated as strings
3355 (e.g. @attr 9=title).
3357 CCL trunction character may be defined (@truncation in file)
3359 * function zget_ExtendedServicesRequest sets waitAction to
3360 waitIfPossible (was wait).
3362 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3365 CCL operator names may be set in field definition files (CCL_bibset).
3366 See ccl/bib1 for an example.
3368 Fixes in ASN.1 compiler for C++ compatibility.
3370 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3371 and "op_or" to avoid conflict with C++.
3373 Fixed problem with GNU readline detection on Redhat 7.0.
3375 Added step-size for Scan backend handler.
3377 Fixed bug that made the frontend server crash when no attribute
3378 set was specified for scan.
3380 Front-end server automatically switches to original working directory
3381 when installed as an NT service. Previously -w had to be specified to
3384 Added extended attributes for retrieval module (data1), so that data1
3385 records carry d1_readXML/SGML attributes. d1_read also supports
3386 null-data rules ( <tag/>)
3388 On UNIX when POSIX threads are available, a separate library libyazthread
3389 is created. Programmers should link with that library and the yaz library
3390 when using threads. The reason for the split was that some applications
3391 on Linux, such as Apache, doesn't work well when using shared objects that
3394 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3395 (or any frontend server) in SSL mode by specifying ssl: followed by
3396 address. Only tested on UNIX.
3398 Added feature for CCL module. Virtual structure s=al or s=ol generates
3399 and-list and or-list respectively instead of phrase search.
3403 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3404 log_mask_str. This was done to avoid name conflicts with other libraries
3405 (such as other PHP extensions).
3407 Added raw OID member for preferred record syntax (request_format_raw)
3408 and returned record syntax (output_format_raw) for backend fetch method.
3410 Config file yaz-config now accepts options so that it returns specific
3411 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3413 Shared library support for UNIX using GNU libtool.
3415 * Modified backend interface. Request/Response struct's replaced by
3416 one read/write C struct. For example bend_fetchrequest and
3417 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3418 Every handler - even search has to be registered in bend_init
3419 handler. This means that the YAZ library no longer refers to
3420 external functions and it makes it possible to make the whole
3421 thing a single DLL/SO.
3423 Added Segment handler for backend server.
3425 Added Zmbol/Zebra administrative functions to YAZ client.
3427 Threaded frontend server on UNIX (when POSIX Threads are available).
3428 Starting the server with option -T enables multi-threading.
3432 Added configure option --enable-comp/disable-comp to control use
3433 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3434 located in sub directory asn.
3436 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3437 in ${exec_prefix}/bin along with the other programs yaz-client and
3440 GNU automake used to maintain makefiles.
3442 Added several OID's.
3444 Changed retrieval module so that we can load records with no abstract
3445 syntax defined. Tagpaths in these records are fully composed of string
3448 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3452 On UNIX, the generated makefile now supports a proper 'make install'.
3453 The prefix can be set via GNU configure to set the install location
3454 (default is /usr/local).
3456 * YAZ programs client and ztest were renamed to yaz-client and
3457 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3458 locations, such as /usr/bin,/usr/local/bin,etc.
3460 * YAZ Header files were moved from include to include/yaz. YAZ Header
3461 files are referred to as include <yaz/log.h> rather than <log.h>.
3462 The YAZ include path (-I ..) is therefore the same as before. Programmers
3463 should update their #include statements or use -Ipath/include/yaz
3464 instead. The main motivation for doing this change is that YAZ header files
3465 can be installed in "standard" locations /usr/include,/usr/local/include
3466 without introducing conflicts, since ALL YAZ header files are stored
3467 in subdirectory yaz (under /usr/include for example).
3469 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3470 rather than project/workspace files. We switched because project files
3471 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3474 Changed name of logging function, logf, to yaz_log, to prevent name
3475 clash with some math-log functions. The YAZ header log.h defines logf
3476 to yaz_log (#define) so there should be no incompatibilities by this
3479 Added bend_start/bend_stop handlers for server. These handler are
3480 called on start/stop of server. For windows they are called whenever
3481 a service is started/stopped.
3483 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3484 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3485 in util/yc.tcl. The auto-generated C code structures are, in a few
3486 cases, incompatible with the old decoders. There are differences in the
3487 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3488 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3489 The preprocessor variable ASN_COMPILED is defined when the compiled
3490 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3491 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3492 wish to use the old encoders/decoders you can specify --disable-yc
3495 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3496 version so that it supports both new - and old version of DB Update
3498 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3499 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3500 change. The name parameter can be set to 0 in which no name is specified
3501 for the construction. The macros odr_implicit and odr_explicit sets name
3502 parameter to zero for the construction involved. New macros
3503 odr_implicit_tag and odr_explicit_tag are similar to the others,
3504 except that a name parameter is added. For programmers' that don't use
3505 ODR they probably only need to change the call to z_APDU and z_External.
3507 Added access control facility by interfacing the TCP wrapper library.
3508 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3509 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3510 name of the daemon and enables the access control as specified in
3511 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3513 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3514 den Dool <H.M.vdnDool@kub.nl>.
3516 Added reference ID parameter to most functions in server API - refer
3517 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3519 Changed name of ccl library to libccl.a (was ccl.a).
3521 Fixed bug in decoder for Explain (Category TargetInfo).
3523 Added support for GNU readline in client. Thanks to Jacob Poulsen
3524 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3526 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3527 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3528 IMPLEMENTATION! This change was made to the development version before
3529 the ZIG decided to retract the amendment. If any users MUST be
3530 compatible with the original Update definition, PLEASE CONTACT US, and
3531 we will include a separate definition corresponding to the old Update
3532 ES. Note that because of the change to the ASN.1 of the
3533 TaskPackageRecordStructure we cannot define a single structure that
3534 will support both versions.
3536 * Added const modifier to buffer parameter for some ODR/BER encoding
3537 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3538 completeWAIS, odr_dumpBER.
3540 Fixed bug in client.c which caused a crash when a scanResponse didn't
3541 contain positionOfTerm.
3543 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3544 * will cause an error in a client if a non-YAZ target sends both a
3545 * list of Scan entries and non-surrogate diagnostics.
3547 Retrieval module enhancements. Tag sets may be typed in the reference
3548 to it. From the .abs-file the "tagset" directive takes a third optional
3549 integer type for the tag set referenced. From a .tag-file the "include"
3550 directive takes a third optional type as well. The old "type" directive
3551 in the tag set itself is still recognized but acts as the default type
3554 Backend interface change. Individual Scan terms returned from bend_scan
3555 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3556 in include/backend.h.
3558 Retrieval module enhancements. Multiple tag sets and attribute sets may
3559 be specified in abstract syntax specs. Revised the error/warning for
3560 logging messages reported by the retrieval module when reading the
3563 Object Identifier system (oid_..) changed. The API is backwards
3564 compatible but the oid-routines now allocates new OID's when needed.
3565 Raw OID's may be specified in oid_getvalbyname.
3567 YAZ now uses GNU configure to generate Makefile(s).
3569 * Minor changes in some of the member names of DeleteResultSetRequest and
3570 DeleteResultSetResponse. See include/proto.h.
3572 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3573 and added member 'languages' in TargetInfo (which was missing).
3575 Changed the way attribute sets are handled in the retrieval
3576 module. These are now cached, just like the abstract syntaxes
3579 Changed YAZ so that it links with compiled ASN.1.
3581 Added Explain-schema definitions and mapping routines. The following
3582 Explain categories have been implemented: AttributeDetails,
3583 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3585 Fixed minor bug in Windows version of Server Library.
3587 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3589 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3591 Added EXTERNAL: UNIverse Resource Report (non-standard).
3593 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3594 ENUMERATED and SET OF.
3596 * Added 'const' to some of the char pointer arguments for the
3597 functions, data1_read_node, data1_getelementbytagname,
3598 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3601 Fixed bug in data1_insert_taggeddata - the last_child member of
3602 parent wasn't initialised.
3604 * Changed data1_read_record and data1_read_node so that the supplied
3605 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3606 doesn't refer to any parts of the "SGML"-buffer.
3608 Fixed bug in server library (Windows version of statserv_remove).
3610 * Changed code so that it compiles as C++. The type definition
3611 of Odr_fun which is a member of Odr_arm was changed. The result is,
3612 that an explicit typecast is needed for the fun pointer when
3613 using Odr_arm - as in:
3614 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3616 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3618 Implemented the new structured date and time definition as approved
3619 by the ZIG. Added schemaId element to the specificTag in Espec-1
3620 (also approved at the last ZIG). Thanks to RVDM.
3622 Added some Object identifiers (RVDM).
3624 Changed the Update Extended Service (RVDM).
3626 Added command "refid" to client which specifies referenceId for
3627 the following requests.
3629 Implemented extended service handling for server. See ztest.c
3630 for an example as well as backend.h. New handlers are registerd
3631 in the Init handler.
3633 * Changed interface for sort in server.
3635 Added new members to statserv_options_block. It allows a server
3636 to read options from another source than just the command line. Thanks
3637 to Charles Woodfield.
3639 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3640 renamed to zboolean. Some C++ compilers complained about the name.
3642 Minor changes to gils.abs. Added index 's' (sort) on title
3643 and date/time-last-modified.
3645 --- 1.4pl2 1998/1/30
3647 Fixed bug in server library regarding inetd mode (-i). This bug
3648 was introduced by release 1.4.
3650 --- 1.4pl1 1998/1/29
3652 Added sort facility in client and backend server interface.
3654 Fixed problem with dependencies in Makefile(s).
3656 Fixed bugs for encoders/decoders of extended services and
3659 Implemented sub-tree feature for schemas. Sub-trees are
3660 referenced in *.abs-files. See explain.abs for an example
3661 of the use of this feature.
3663 Modified bib1.att; local attributes for ANY didn't include
3664 ANY itself (only affects use of the retrieval module).
3666 Fixed bug in plain SGML reader in function data1_read_node:
3667 tags with prefix "var" was incorrectly interpreted as variants.
3669 Added feature "sub-schemas" to enable references to - and definitions
3670 of - group of elements.
3672 * Removed member parent from type data1_element (in data1.h).
3674 Implemented function odr_nullval() that returns the value of
3677 * Removed member num_children from data1_node (in data1.h).
3679 Made NT service interface part of the server library. The
3680 function statserv_main uses the NT service when required and
3681 calls the statserv_start / statserv_close routines.
3683 Routine zget_SearchRequest and zget_PresentRequest fills
3684 resultSetName/Id member with "default" instead of "Default".
3686 Fixed memory leak in server. Request queue member wasn't freed.
3688 Fixed nmem_exit so that memory is freed.
3692 Revised the CCL parser utility to be thread safe.
3694 Added function, oid_ent_to_oid, to replace the function
3695 oid_getoidbyent, which is not thread safe.
3697 * Added nmem_init and nmem_exit to initialize and release
3698 NMEM resources. Function nmem_init should be called once in the
3699 initial thread before NMEM/ODR is used. statserv.c and client.c
3700 have been changed accordingly. The change was necessary to make
3701 NMEM thread safe. The NMEM memory pool is shared amongst threads
3702 in a process. Unix-based applications will still work fine without
3705 Added NT Services interface for the the Z39.50 (statserv) Server.
3706 Refer to the ztest.c source on the usage.
3708 Windows 95/NT port using MSVC5.0. Project files are included in the
3711 * Defined new 'global' handle for the retrieval (data1) system. The
3712 new handled, data1_handle, describes the state of the data1 system.
3713 This handle is passed as first argument to virtually all
3714 data1 related routines. The functions data1_create and data1_destroy
3715 creates and destroys a data1 handle respectively.
3717 Added ODR encode stream member to all backend request structures
3718 init, search, scan etc. This stream should be used to allocate all
3719 memory used for the response when thread safe operation is needed.
3721 Changed the comstack utility, cs_addstr, to be thread safe. The
3722 returned hostname string returned by the function is now part the
3725 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3726 function. The cs_straddr takes a COMSTACK handle as argument, so this
3727 function must be used after cs_create and before bind/connect.
3728 This function is thread safe.
3730 Moved test server to 'ztest' directory - generic server code still
3731 in 'server' directory.
3733 Made prefix query (pquery.c) utility thread safe.
3735 Added new function modifier YAZ_EXPORT to 'export' public DLL
3736 functions when using windows (see include/yconfig.h).
3738 Added definitions to the OID database (util/oid.c) (RVDM).
3740 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3742 Added call to ccl_rpn_delete in client program.
3744 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3745 release of RPN structure.
3747 Added support for C++, headers uses extern "C" for public definitions.
3748 With input from RVDM.
3750 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3751 Thanks to Ronald van der Meer (RVDM).
3753 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3755 Added support for private extensions to the OID database
3756 (oid_setprivateoids()). Thanks to RVDM.
3758 Added optional, physical ANY (key replication)
3760 Fixed null-reference problem in GRS-1 output filter.
3762 Proximity operator added to Prefix Query Format (PQF).
3764 In test client command "base" accepts multiple databases.
3766 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3770 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3772 Smallish bug-fixes in the new encoders/decoders (explain).
3774 Bug fixed in DeleteRequest.
3776 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3778 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3780 Added SOIF syntax (using private OID for now) to retrieval module and client.
3782 Added Update extended service.
3784 Added SearchResult-1 additional info structure.
3786 Added optional CCL (ISO8777) interpreter as separate module. Available
3789 --- 1.2 1996/6/10 (1st anniversary release)
3791 Added Summary record syntax. Lightly tested.
3793 Added OPAC record syntax. Untested.
3795 Added ResourceReport service encoders/decoders. Untested.
3797 Fixed bug in z_Unit - wrong tagging on unitSystem.
3799 Fixed bug in the DiagRecs decoder.
3801 Added options for max PDU size and session timeout to frontend-server.
3803 Added documentation of query-language parsers and other supporting utilities.
3805 [frontend-server] Added Attribute set to the bend_scanrequest API.
3807 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3808 surrogate diagnostics were generated.
3810 [retrieval] Allow multiple local values for attribute.
3812 [retrieval] Allow multiple attributes per element in .abs files. index type.
3814 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3816 --- 1.1pl2 1996/4/10
3818 Minor changes, mostly specific to Zebra's requirements (retrieval)
3822 Repaired bug in frontend server when running multiple listening
3823 endpoints in dynamic mode.
3825 z_External() now won't break if a known, ASN.1 value comes encapsulated
3826 in an octet-string. The value will pass through unmodified in an Odr_oct.
3828 Added a bit of code to the demo client to decode & display
3829 ASN.1-structured records represented in the octet-aligned branch of
3830 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3832 Added z_ext_getentbyref() to the ASN module. Doc updated.
3834 * Completed the SCAN definition in the ASN module. This may break SCAN
3835 code based on older YAZ-versions at compile-time. The fix is easy -
3838 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3839 under the SCAN definition. Remember to initialize this, server-people.
3841 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3842 that this does not extend to ODR and ASN.
3844 Comstack allows insertion of established socket (primarily for
3845 inetd-operation of servers). Doc updated.
3847 Front-end server can now start from the inetd in TCP mode. Doc
3850 --- 1.0pl4 1996/1/24
3854 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3855 the rank and record number.
3857 Adjustments to the frontend server.
3859 Fixed diagnostic BER dumper. It ignored the file argument.
3863 Various changes to retrieval module.
3865 Changed the union discriminators of the protocol files from enums to
3866 ints paired with #defines.
3868 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3871 *Changed operator in the RPN structure to 'roperator', again to avoid a
3874 Fixed problems in Explain decoders/encoders.
3876 --- 1.0pl2 1995/12/6
3878 Memory bug in log module fixed.
3880 --- 1.0pl1 1995/12/5
3882 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3884 Bug in Explain DatabaseInfo module fixed.
3886 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3890 The shift to v1.0 signals that we now consider the *core* functionality
3891 of YAZ reasonably stable (the core being more or less equivalent to
3892 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3893 tested (Explain not at all - though that will happen soonish).
3895 Minor changes to code to support Windows port.
3897 Various minor changes after we're getting to use GRS-1 & co. more.
3899 Added Espec-1 format.
3901 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3902 of the protocol and it cannot be selected when encoding (maps into 'string'
3903 when decoding). Needed to talk to some servers.
3905 Demo client can request simple element set names.
3907 Added Diagnostic Format encoders/decoders.
3909 Added simple Close handling to frontend server (no hooks for resource
3910 reporting yet), and demonstration client.
3912 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3914 --- 1.0b3 1995/08/24
3916 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3917 handled incorrectly when records were requested in the searchResponse. This
3918 will only affect you if you use the frontend-server.
3920 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3921 Test-client will ask for and print GRS1. Ztest will return dummy records
3924 Added Explain encoders/decoders to the service-level API. Untested.
3926 Added Extended Services: Item Order encoders and decoders to the Service-
3927 level API. Untested. We could use a recent copy of the pertinent bits
3928 of the ILL protocol to add those bits.
3930 Added diagnostic format 1 encoders/decoders to the service-level API.
3933 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3934 odr_cons.c, which causes a more correct output.
3936 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3937 was always set to 0 when no records were requested in the searchRequest.
3939 * Added better external-handling. This shouldn't harm old code that
3940 *encodes* externals. It can break code that looks for a
3941 'single-ASN1-type' representation, since those types that are known
3942 are now decoded immediately. Look at the SUTRS sample code in
3943 seshigh.c and client.c. Documentation updated.
3945 Handling of structured records in bend_fetchresponse. Length -1 marks
3946 structured record, type is deduced from format field.
3948 --- 1.0b2 1995/06/27
3949 Fairly quick maintenance release to add SUTRS support.
3951 Fixed handling of SUTRS records in the demonstration client.
3953 * Added format field to the bend_fetchrequest and bend_fetchresponce
3954 structures of the backend API (frontend server). When the record is
3955 returned, the value of the format field is mapped to an OID. The
3956 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3957 of the record. The special value VAL_NONE in the bend_request means
3958 that no specific format was requested by the client. Documentation
3959 updated accordingly. Test server (ztest) will return a fixed dummy
3960 SUTRS record if your client requests SUTRS.
3962 Documentation updated accordingly.
3964 You can now set external libraries and RANLIB support in the top-level
3968 First public release.
