3 Build packages for Ubuntu Trusty Tahr 14.04 LTS
5 wrbuf_cstr: fix off by one error.
7 wrbuf_buf: make it always return non-NULL
8 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
12 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
14 zoomsh: offer option -a apdulog
15 As we're used to from yaz-client and GFS based servers.
17 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
18 existing setting apdulog takes effect.
20 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
25 Add re-entrant CQL/Solr/RPN query conversion functions.
26 The re-entrant functions are: cql_transform_r,
27 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
28 These have same functionality as cql_transform,
29 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
30 return the additional infomration as WRBUF to make them re-entrant.
32 Remove CQL to Solr conversion and base solr_transform_t on
33 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
34 data structure as cql_transform_t.
36 cql2pqf utility allows RPN to Solr conversion
38 Fix assert in ZOOM when http connect fails YAZ-757
42 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
44 wrbuf_cstr: make it thread safe YAZ-753
46 yaz_log_init_file may take fd=<no> to open log file at the FD given.
50 Offer new utility function zget_AttributeList_use_string.
52 New conversion step, solrmarc, for record conversion module.
56 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
57 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
62 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
63 The standalone ZOOM sort was completely broken since 5.0.13.
65 ZOOM: generate event Connect rather than None for partial connect
66 (in fact getaddrinfo resolving).
68 ZOOM: only supply clientIP for InitRequest. Rather than for all
71 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
73 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
74 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
75 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
77 New "Facets" section in the documentation.
81 Call exsltRegisterAll in yaz_init_globals, so that all applications
82 using YAZ will have EXSLT things enabled.
84 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
86 Update various URLs to the re-organized SRU pages at LoC.
90 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
93 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
94 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
95 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
100 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
102 --- 5.0.15 2014/02/24
104 Fix gcrypt not properly initialized YAZ-740.
106 --- 5.0.14 2014/02/19
108 Describe memcached option for ZOOM.
110 ZOOM: throw present request out of range again YAZ-739
111 Was removed in YAZ 5.0.13.
113 --- 5.0.13 2014/02/18
115 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
116 with localtime_r when threads + fork is used (such as Metaproxy).
118 yaz-config: quote some RHS values (that might include blanks)
120 zoomsh: shows SearchResult-1
122 zoomsh: sortby command
124 zoomsh: use proper list of connections and result sets YAZ-725
126 Avoid yaz_log in sigterm handler for GFS YAZ-737
127 Logging is still performed, but outside sig handler.
129 New ZOOM C feature: result-set caching with memcached. Example:
130 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
132 Remove SSL via OpenSSL support YAZ-732
133 Also deprecate two functions from comstack that aren't working with
134 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
136 Revert "Bison: use %name-prefix directive rather than -p option"
138 --- 5.0.12 2014/01/22
140 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
142 SRU GET/Solr base URLs may hold additional ?args YAZ-729
143 ZOOM option extraArgs already does this, though. It seems useful
144 when dealing with Solr targets to limit by filter, eg.
145 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
147 Remove #fragment for HTTP request encoding YAZ-730
149 Doc: Update list of DLLs/LIBs
151 Doc: update href link to Unix utils and Git.
153 --- 5.0.11 2014/01/15
155 ZOOM: fix "lost connection" problem with servers that uses both squid
156 and another proxy behind it that returns Location headers with relative
159 zoomsh: do not use readline for stdin (no tty) YAZ-724
160 Just use fgets in that case. If the user hits Ctrl-D a new-line
163 zoomsh: empty command ignored YAZ-723
164 rather than performing exit of zoomsh.
166 yaz-url utility offers option -v to enable verbose mode.
168 yaz_url uses yaz_check_location and offers verbose mode.
170 Add new function yaz_check_location.
171 This function gets an absolute URI from Location (HTTP redirect).
173 cookie API: introduce yaz_cookies_reset
175 Update cql.y for newer bison YAZ-720
176 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
177 longer supported. Instead one must use %lex-param and %parse-param .
179 --- 5.0.10 2014/01/09
181 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
184 rpn2solr: support truncation left(2), left&right(3) YAZ-718
186 Mention SRU version 2.0 in yaz-client man page.
190 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
195 Make cs_parse_host public.A
197 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
198 introduced in YAZ 5.0.6.
202 Fix buffer corruption for yaz-ztest record fetch.
206 Allow yaz-ztest to return user-defined records (one record per file).
207 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
209 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
210 Use the stream write instead of odr_printf which has a 4K tmp buffer.
212 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
216 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
217 can read and write this format. For record format JSON, yaz-ztest returns
218 MARC-in-JSON records.
220 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
221 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
225 Improve error reporting for ICU chains YAZ-707
226 Report config element+rule when ICU status is "failure".
228 ZOOM: stop fetching if present response has no records YAZ-710
229 Some targets return less records than their hit count would suggest.
230 This prevents ZOOM from continuing to fetch records if any present
231 response has 0 records in the response.
233 Ensure that GFS calls exit if any listener fails YAZ-710
234 Before, if XML config was in use, it would start the default
239 yaz-ztest: -V shows version (like yaz-client -V)
241 New iconv encoding: danmarc YAZ-692
243 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
245 daemon: only wait for immediate child rather than all children. YAZ-704
247 yaz-client: fix setting of SRU record schema. If scheme was unset, it
248 could lead to invalid memory reference.
252 yaz-ztest returns schema for MARCXML test records. SRU require that
253 recordSchema for records.
255 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
256 instead of non-surrogate diagnostic. This is a per-record failure.
258 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
259 may refer to multiple listeners now. Attribute listenref is a comma separated
262 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
263 option is given for GFS, the dirname of filename (for -f) is used
264 as prefix for options such as cql2rpn, ccl2rpn, etc.
266 Content-Type charset fixes YAZ-701 . Do not inspect charset in
267 Content-Type header for SOAP when decoding SRU. The payload (XML)
268 itself tells what encoding it is. In response, never supply encoding
269 in Content-Type. The response payload (XML) tells what it is (with no
270 encoding in XML it's UTF-8).
272 HTTP decoding: allow blanks in URL paths YAZ-700
276 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
277 and facets. Ensure recordData and recordSchema are always present in
278 record element, because they are required.
280 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
283 Simplify in a lot of places using odr_strdupn.
285 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
289 Increase various buffers in GFS's statserv_options_block
290 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
291 This change makes many type-casts redundant, and, thus simplifies code.
293 Remove last bits of WAIS support.
295 Remove member 'size' from Odr_oct.
297 Slim down the public part of 'struct odr'. Most elements are not part
298 of struct Odr_private.
300 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
301 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
302 In particular facets are supported in both client - and server side.
303 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
304 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
305 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
306 both request/response). This is what a search handler in the GFS
307 will see (regardless of whether operating in SRU mode or Z39.50).
309 Changes to the srw.h (SRU/Solr) definitions include:
310 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
311 (char*), which replace union query and query_type (int). This is because
312 SRU 2.0 supports a queryType parameter. This also means that, to carry
313 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
314 x-pquery=PQFstring (extention parameter). The extension parameter
316 - New element, packing, that has information about SRU
317 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
319 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
321 New element, packing, in Z_SRW_explainRequest.
323 New elements in Z_SRW_scanRequest, queryType and scanClause.
324 These replace query_type and scanClase untion. This is similar to what
327 --- 4.2.69 2013/10/01
329 GFS: log when closing down - at least SIGTERM YAZ-684
330 Also change formatting WRT PID logging a bit.
332 Improve display of MARC records with multi-byte subfield IDs YAZ-695
333 In some rare cases subfield identifiers are multi-byte characters.
334 This will try to deterime length of those and split accordingly.
335 This affects display in line mode as MARCXML/MarcXchange. The encoding
336 of ISO2709 is the same.
338 Change inp argument to const for yaz_read_UTF8_char.
340 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
342 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
344 Better check of marc leader info YAZ-691
345 Problem is that some systems generate MARCXML/MarcXchange with
346 funny headers. These will not work if encoded as ISO2709.
347 Some tests produce new output, due to updated warning messages
349 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
351 yaz-client: display MAB records YAZ-689.
352 Thanks for Heiko Jansen for this patch.
354 New utility z_get_HTTP_Response_server which allows both HTTP server name
355 and HTTP server URL to be given in response.
357 Debian: do not depend on obs tcl8.3.
359 Debian: do not depend on obs libicu36-dev.
361 --- 4.2.68 2013/09/23
363 GFS: pass additionalSearchInfo to search memeber search_input if
364 given. Otherwise pass otherInfo. Request for facets and other search
365 related things will be passed there in future versions of YAZ.
367 New ZOOM setting, authenticationMode, which allows authentication
368 paramters to be encoded in the URL rather than via HTTP Basic auth.
371 rpn2solr: fix nested AND/OR handling. YAZ-685
373 Add comparison routines for some Z-types, such as NamePlusRecord,
374 RPNQuery, Query, RecordComposition and OtherInformation.
376 --- 4.2.67 2013/09/19
378 Don't decode MAB as MARC. Just like we don't attempt to decode
379 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
381 CCL: allow quoted terms for date ranges. YAZ-681
383 Introduce ccl_parser_qual_search. This function makes old function
384 ccl_qual_search, from YAZ 2, available again.
386 Add yaz_facet_list_to_wrbuf. YAZ-683
388 --- 4.2.66 2013/09/11
390 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
391 schema was given for search. YAZ-675
393 Add Solr date range searches. YAZ-621
395 --- 4.2.65 2013/08/22
397 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
399 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
401 ISO2709/MARC parse most octet aligned records; not just those that
402 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
403 MARC parse more records instead of just dumping as is. YAZ-670
405 ZOOM: proper caching for variations of record schema. YAZ-671
407 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
409 --- 4.2.63 2013/07/17
413 --- 4.2.62 2013/07/11
415 New utility z_get_HTTP_Response_details - an extended version of
418 New utility yaz_url_get_error which returns error message of last
419 failed yaz_url_exec call.
421 yaz-url and url functions: allow max HTTP redirects to be controlled.
423 New functions yaz_file_glob2, yaz_xml_include_glob.
424 These functions takes a flags parameter, which, for now only controls
425 whether to fail inclusion of a non-existing file (without glob
426 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
428 --- 4.2.61 2013/06/20
430 For MARC XML parsing, allow record without leader. A fake/default leader
431 is inserted and a warning is tagged with the record.
433 ICU: fix leak in in icu_iter_get_org_info.
435 --- 4.2.60 2013/06/14
437 ICU: fix bug in icu_iter_get_org_info (un-init variable).
439 --- 4.2.59 2013/06/11
441 Implement z_HTTP_header_remove.
443 --- 4.2.58 2013/06/11
445 ICU: Disallow 0 ptrs for some ICU string utilities.
447 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
448 returns original tokens (before normalization).
450 CCL: avoid z39.58/regex truncation when not needed. Apply only the
451 conversion of those masks, when absolutely necessary.
453 CCL: configurable masking character - @mask. Default masking character
456 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
457 full response anyway, so a Transfer-Encoding header will obstruct the
460 --- 4.2.57 2013/05/15
462 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
463 picking a socket. Problem is that some systems has IPV6 support, but
464 we can't create sockets for them, so we pick AF_UNSPEC first.
466 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
467 use content_len to determine resulting Content-Length in HTTP response
468 and NOT Content-Length supplied in headers by user.
470 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
471 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
473 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
476 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
477 with big endian and unsigned char (by default).
479 --- 4.2.56 2013/04/26
481 Fix yaz-client connect (crash in 4.2.55).
483 --- 4.2.55 2013/04/26
485 Fix proxy/host problem for ZOOM that could occur if unix sockets
488 New Debian package libyaz4-dbg.
490 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
491 differently in tcpip_close.
493 --- 4.2.54 2013/04/17
495 Windows installer of YAZ includes YAZ4J as a component.
497 CQL: allow "extra terms" again, by default. Thus, the CQL parser
498 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
499 and earlier. CQL parser may operate in strict mode where queries
500 not conforming to the standard BNF are rejected (syntax error).
501 Whether the CQL parser operates in strict mode is controlled with
502 cql_parser_strict . Strict mode enabled with option -S for utilities
503 cql2pqf and cql2xcql .
505 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
507 --- 4.2.53 2013/04/10
509 New charset, MARC-8c, which is like MARC-8 but allows control characters
510 0x01 through 0x1F, except ESC to be passed through verbatim.
512 Fix a problem with duplicate sub field character in MARC output. Problem
513 happened only when output was MARC-8 encoded.
515 --- 4.2.52 2013/04/03
517 yaz-ztest: Use hash for fake hit count. Before, random number was used.
518 This is problematic for unit tests using yaz-ztest. This patch also makes
519 a hash for CQL queries. For RPN, any term with a leading digit will be
520 treated as pseudu hit count (to force any particular hit count by a client).
522 yaz-ztest: return unique MARC dummy records. Beyond record offset
523 24, the author surname is patched with offset to make all records
526 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
527 on system wide default (/proc/sys/net/ipv6/bindv6only).
528 @4 binds to IPV4 only. @6 binds to IPV6 only.
530 Update CQL API documentation a bit
532 CQL: don't accept extra terms for queries. Makes the CQL parser
533 stricly conformant to the standard.
535 --- 4.2.51 2013/02/12
537 GFS: scan handler gets extra_args from request and may return extra
538 response data . That's for SRU only.
540 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
542 --- 4.2.50 2013/01/30
544 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
546 OPACXML: sync spelling of availabilityDate in XML to that of Schema
547 opaxxml.xsd. The schema had the correct spelling of this member always.
548 The ASN.1 was mis-spelled and still is (API change) - we are
549 not changing this. However, the OPAC to XML conversion had yet
552 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
555 New function, z_ext_record_oid_nmem, which is similar to
556 z_ext_record_oid but takes NMEM rather than ODR
558 --- 4.2.49 2013/01/18
560 ICU: New conversion element 'join' which joins tokens into one
561 with a custom character given by rule attribute.
563 --- 4.2.48 2013/01/10
565 New GFS search member: present_number. This is a hint to the
566 search handler how many records are going to be fetched immediately
567 following search. There's no guarantee that it's going to be the case,
568 since it depends on hit count (for Z39.50 piggyback) and whether errors
571 Make a few functions static (private). The functions getbyte_stream,
572 ungetbyte_stream and yaz_gets are now private. They were never declared
575 yaz-marcdump: exit(5) for serious decoding errors
577 ISO2709 decoding: be more picky WRT header
579 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
580 was only used as to indicate that next-result-set-position should be
582 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
583 Based on patch from Ashley Sanders.
585 Make some functions static/private in PQF parsing. Those functions were
586 never declared in a public header and so should not be in use by
587 applications based on YAZ.
589 --- 4.2.47 2012/11/23
591 ZOOM: special options to control APDU logging.
592 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
593 logging of APDUs until "saveAPDU" option is set again. If logging is
594 already enabled the effect is that current APDU buffer is cleared.
595 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
596 logging (default behavior on new connection).
597 The APDUs sent/received can be obtained by using
598 Using ZOOM_connection_option_get(c, "APDU") or
599 ZOOM_connection_option_getl(c, "APDU", &l).
601 GFS: relay implementation_version from backend
602 From 3.0.40 and later, implementation_version from backend was
603 not used in init response at all.
605 --- 4.2.46 2012/11/15
607 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
608 mode at all. Probably never did.
610 Make a new version of ztest.pem that, at least, is not expired.
612 --- 4.2.45 2012/11/13
614 Fix description of CCL directive 'case'.
616 More tight checking of form arguments (yaz_uri_to_array). Makes
617 YAZ better at rejecting big and/or bad POSTs.
619 SRU decoding does not report more than up to 10 invalid arguments.
621 rpn2cql: less quotes in generated terms. Semantics unchanged, but
622 it's prettier this way.
624 --- 4.2.44 2012/10/25
626 New utility yaz_decode_init_diag. Defined in proto.h.
628 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
629 given for unix local socket.
630 The COMSTACK string for doing so is:
633 unix:/myfile:tcp:localhost:9999/mybase
634 unix:/myfile:localhost:9999/mybase
635 unix:/myfile:http://fakehost/mybase
637 debian: Use dpkg-buildflags in build process.
639 --- 4.2.43 2012/10/19
641 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
642 global's SRU service uses a recordPosition scheme starting from zero.
643 First record's position should be one
644 according to the standard.
646 --- 4.2.42 2012/10/18
648 Allow more namespaces for SRU. This is to allow, for example, an
649 incorrect namespace returned from server
650 http://services.igi-global.com/sru .
652 Minor fixes for compilation on Windows.
654 --- 4.2.41 2012/10/11
656 daemon: log total number of bad signals from child on stop so that it
657 is more easy to spot problems with child worker processes.
659 retrieval: empty backend name attribute omits element set
660 from being used in retrieval.
662 --- 4.2.40 2012/10/04
664 Implement Solr sort strategy "solr", similar to sru11 sorting.
665 This will implement the correct parameters on Solr requst to do
668 --- 4.2.39 2012/09/28
670 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
673 MARC: Extra/missing indicator handled for MARCXML.
674 The indicator length is given in header and is the same for the
675 whole record. If attributes ind1, ind2 are missing, then content
676 character defaults to blank. Extra indicator attributes (beyond)
677 indicator length are treated as an error.
679 Reformat: delete trailing whitespace
681 --- 4.2.38 2012/09/17
683 MARC: fix non-ASCII characters for leader. This is to ensure we can
684 generate XML in UTF-8.
686 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
687 in one node with structure word.
689 --- 4.2.37 2012/09/04
691 yaz-json-parse: JSON output may be pretty printed by using option
694 Increase default value of max message for Z39.50 Init for GFS, ZOOM
695 and yaz-client. Old value was 1 MB. New value is 64 MB.
697 --- 4.2.36 2012/08/22
699 yaz-client: don't display bogus records from SRU servers. Some SRU servers
700 return more records than given by *maximumRecords*. Skipping those in
703 record_render: simplify buffer return handling and fix at least one bad
704 memory reference, that broke the test_embed_record sometimes.
706 Allow http://user:pass@host notation for yaz_url_exec.
708 zoomsh: allow shell command to be executed. Via the system(3) call.
710 yaz_poll: Allow num_fds == 0
712 yaz-client: fix bad encoding of "itemorder item". The itemorder
713 item <no> - command forgot to use length of encoded Item Request
714 package. Error present since YAZ 3.
716 yaz-ztest: fix bad usage of session handle. Bug was introduced when
717 result sets were saved (271a9c83).
719 SRU recordPacking: guess record packing in response rather than looking
720 at the recordPacking element which, OF COURSE, changed semantics in SRU
723 Decode SRU 2.0 responses. The official namespace for responses, according
724 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
725 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
726 nature.com's server, however, usee namespace
727 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
728 we are now using a glob-expr to match up the namespace. ZOOM C and
729 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
730 I can not find a single real example showing the "real" namespace in
731 the documentation from OASIS. The namespace for requests is different
732 from responses, but this is not added to YAZ yet, when we don't encode
735 --- 4.2.35 2012/06/26
737 zoom/record_render: add support for Base64 decoding fo MARC records
738 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
739 which will decode base64 + ISO2709 marc-8 encoded material from text node
742 --- 4.2.34 2012/06/07
744 Add missing definitions ZOOM_resultset_get_facet_field_by_index
745 and ZOOM_resultset_facets_names.
747 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
750 Change APDU dump printing to avoid long leading blanks. For levels 16
751 or larger the level is shown and the indentation is truncated but
752 recursed with modula 8. This makes it still reasonable easy to read
753 - even for nested BER dumps.
755 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
756 return 0 (incomplete package) in case where the BER package was
757 considered too nested (return value of -2).
759 dumpber: lines of level 15 are not indented further. Two spaces per
760 indentation; indentation 15 or more is indented to a fixed indentation
761 and augmented with a level=<no> indication.
763 zoomsh: increase max size of command+args
765 GFS: No limit in RPN buf size in CQL to RPN conversion.
767 --- 4.2.33 2012/05/09
769 New function for daemon utility, yaz_daemon_stop .
771 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
773 --- 4.2.32 2012/04/25
775 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
776 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
778 --- 4.2.31 2012/04/23
780 YAZ daemon utility relays SIGUSR1 to child process.
782 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
783 would result in en empty database list - which in turn would result in
784 encoding failure for search.
786 Fix reading beyond string in yaz_sort_spec.
788 --- 4.2.30 2012/04/11
790 Add two new SRU diagnostics:
791 236: Access to specified database denied
792 1015: Init/AC: Maximum number of simultaneous sessions for Userid
794 Document the very useful ZOOM-C option "apdulog".
796 CQL to RPN: term may be passed through verbatim. This is enabled with
797 truncation.cql . The assumption being that the term is already CQL.
799 --- 4.2.29 2012/03/20
801 record_conv: leader spec may be given for marc element.
802 The leader spec is given as attribute leaderspec for element marc.
803 For example to convert a MARC21 record from MARC-8 to UTF-8:
804 <marc inputformat="marc" outputformat="marc"
805 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
807 record_conv: allow user-XSLT params. For example:
808 <xslt stylesheet="MARC21slim2DC.xsl">
809 <param name="myparameter" value="myvalue"/>
810 <param name="otherparameter" value="othervalue"/>
813 record_conv: fix error handling for missing marc charsets.
815 CQL: fix extra terms in wrong order.
817 --- 4.2.28 2012/03/06
819 record_conv: modify new API for conversion types. The conversion types
820 may be passed in new functions yaz_record_conv_configure_t and
821 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
823 Avoid mixed statement/variable declare; fixes compilation with Visual
826 --- 4.2.27 2012/02/28
828 Add non-standard SRU diagnostic: 235: "Database does not exist".
829 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
830 Update SRU to Bib-1 diagnostic maps accordingly.
832 CCL: add two new diagnostics for unsupported masking. The new
833 diagnostics are: "Embedded truncation not supported" and
834 "Single charcacter mask not supported".
836 --- 4.2.26 2012/02/23
838 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
840 --- 4.2.25 2012/01/11
842 Build YAZ for Ubuntu Oneiric.
844 CCL: allow parantheses for proximity operands. For example CCL query
845 (a) % (b) is now allowed.
847 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
848 marked dead, rather then being destroyed. If not, the session memory is
849 being free'd before the search/scan handler is finished. Also destroy
850 'request' memory in request_release rather than in various places,
851 which resulted in leaks from time to time.
853 --- 4.2.24 2011/12/21
855 cql_sortby_to_sortkeys: honor sort prefix.
857 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
858 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
859 The rpn2cql family of functions now always returns quoted CQL terms.
861 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
863 --- 4.2.23 2011/12/15
865 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
866 sequence is treated as one. For example, &&a=b&&&c& is identical to
869 --- 4.2.22 2011/12/05
871 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
872 APDUs for a connection to a WRBUF.
874 --- 4.2.21 2011/11/23
876 Fix cql_sortby_to_sortkeys. Completely broken before.
878 Make CCL's @truncation work again.
880 --- 4.2.20 2011/11/09
882 New ZOOM connection setting: tproxy. It's like proxy, but does not
883 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
884 to set resolved address + port for a connection outside ZOOM itself.
886 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
888 --- 4.2.19 2011/11/07
890 Fix uninitialized variable in Solr spell support (could cause SEGV
891 for SRU response decoding).
893 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
894 back-end's addinfo through into the ZOOM response addinfo.
896 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
897 they are separated by a colon and a space rather than simply
900 --- 4.2.18 2011/10/28
902 Add support for Solr spell-checking/suggestions through ZOOM.
903 If a Solr target has been configured correctly for spelling-checking
904 and suggestions, these will now be returned on the ResultSet option
905 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
907 --- 4.2.17 2011/09/28
909 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
910 with a flag whether to substitute escape sequences or not.
912 --- 4.2.16 2011/09/22
914 Fix nmem_strsplit_escape to substitute escape char properly.
916 New option for zoomsh -e , which makes it abort on first error and
917 return process exit code to indicate success/failure.
919 YAZ options utility supports special option -- which makes all it treat
920 all following arguments as non-options.
922 --- 4.2.15 2011/09/16
924 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
925 searched if absolute filename is given.
927 Fix conv_xslt() error-reporting when stylesheet is not found.
928 (The value of fullpath is meaningless in this situation.)
930 --- 4.2.14 2011/09/07
932 Fix problem in CQL sort node creation: un-initialized memory.
934 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
935 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
936 CQL sortby depending on whether Type-1 or CQL is actually sent to the
939 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
940 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
942 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
943 will make it possible to use both single-character mask (#) and wildcard (?)
944 in CCL . Throw diagnostic for left truncation because that is not supported
947 --- 4.2.13 2011/09/01
949 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
950 cases using escapes (\-sequences) and masking.
952 PQF parse fix: A trailing backslash followed by end-of-string (\0)
953 would result in a read one byte beyond string.
955 rpn2ccl may use Z39.50 masking for terms (t=z).
957 ICU check fix. Don't include library -lCrun on Solaris, unless present.
959 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
960 not --cppflags (which seeems like an error in icu-config).
962 --- 4.2.12 2011/08/27 RPM package only
964 cql2ccl: fix conversion of terms: operator characters were not
967 --- 4.2.11 2011/08/25 RPM package only
969 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
970 CCL parser will map both # and ? to their regular expression
971 quivalents (. and .*).
973 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
974 of reserved CQL characters.
976 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
977 is, so that they are passed through.
979 --- 4.2.10 2011/08/24
981 ZOOM SRU mode: more aggressive re-connect.
983 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
984 made available as a utility function, declared in <yaz/logrpn.h>
986 rpn2cql_structure() supports proximity nodes (except that the Type-1
987 proximity node's "exclusion" binary is ignored, as there is no way to
988 express that in CQL). Fixes bug #4564.
992 Fix SEGV that could occur if set command of zoomsh was given without
993 value (2nd argument).
995 Fix SEGV that could occur if unsupported transport was given for
996 COMSTACK - say https (when SSL was unavailable).
998 Build yaz-url on Windows too.
1000 --- 4.2.8 2011/08/11
1002 New utility to get web content. Header is url.h. A command line tool
1003 yaz-url is part of the distribution and packages.
1005 Fixes for SSL COMSTACK (when gnutls is in use).
1007 New functions yaz_base64{encode,decode}. Header is base64.h.
1009 --- 4.2.7 2011/08/03
1011 ZOOM C includes HTTP response buffer as additional info if it fails
1012 to decode the SRU response.
1014 Make wrbuf_json_puts available.
1016 --- 4.2.6 2011/07/28
1018 zoom: throw diagnostic for invalid value for option "sru". Before a
1019 bad SRU request was sent.
1021 Adding new utility wrbuf_vp_puts.
1023 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1025 --- 4.2.5 2011/07/21
1027 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1028 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1029 redirect was used at the same time.
1031 MARC line mode decoding: be less picky about length given - first
1032 5 digits of header that is.
1034 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1036 Changes to decoding of SRU records: a record with recordPacking=xml is
1037 modified with a new root element <yaz_record> if the recordData contains
1038 multiple children elements. This is to make the record XML parseable
1041 RPN to Solr conversion: encode special characters.
1043 Generic Frontend Server: fix uinitialized member, stepSize.
1045 --- 4.2.4 2011/06/21
1047 Fix a bug in SRU decoding of records.. The database records stored
1048 had un-initialized memory, but it would only be seen with yaz_record_render
1049 and type_spec="ext" .
1051 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1053 --- 4.2.3 2011/06/17
1055 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1057 --- 4.2.2 2011/06/10
1059 Add new utilities to convert from CQL to CCL . These utilities have
1060 prefix cql_to_ccl defined in cql.h.
1062 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1063 lead to memory heap corruptions when ICU utilities were in use.
1065 --- 4.2.1 2011/06/07
1067 Make compilation work without Libxml2.
1069 yaz-client: remove redundant blanks in display of searchResult-1 term
1072 --- 4.2.0 2011/05/18
1074 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1075 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1077 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1078 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1079 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1080 Note that the CQL sortby spec is only converted when the GFS is already
1081 converting from CQL to RPN (cql2rpn element).
1083 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1084 specify whether to collapse delimitors or not. The existing nmem_strsplit
1085 do collapse (collapse parameter = 1).
1087 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1089 Rename internal func yaz_use_attribute_create. While non-static, this
1090 function is not declared in a public header.
1092 --- 4.1.7 2011/03/15
1094 Add -lCrun when linking with ICU on Solaris.
1096 More quicks character set conversions for OPAC records.
1098 --- 4.1.6 2011/03/10
1100 fix problem with record_render: records were converted (character set
1101 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1103 --- 4.1.5 2011/03/08
1105 SRU: add methods for handling DADS SRU-proxy facets.
1107 Separate OPAC record character set for ZOOM_record. yaz_record_render
1108 allows a character set given as charset=from/opacfrom,to where 'from' is
1109 the character set of a bibliographic record, 'opacfrom' is character set
1110 of OPAC record and 'to' is the target character set.
1112 --- 4.1.4 2011/02/21
1114 yaz-client: show may XML format records. Command show followed by 'format'
1115 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1118 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1121 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1123 --- 4.1.3 2011/01/27
1124 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1126 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1127 this package can be distinguished from other vendors.
1129 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1130 as determined by configure
1132 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1134 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1135 returns no error and no record, the present request is considered
1136 partial (only a subset of the records could be returned by backend), and
1137 so it is appropriate to set Present Status to partial-4.
1139 --- 4.1.2 2010/11/02
1141 Move yaz-config man pages to section 1.
1143 More documentation about Solr.
1145 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1146 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1147 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1148 peers on some Linux systems. However, in general that does not work
1149 so YAZ can not rely on that to work. Debian changed behavior in this
1150 respect from Debian lenny to Debian squeeze (still testing as of Oct
1152 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1154 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1156 --- 4.1.1 2010/10/05
1158 Fix yaz-config output: echo_source not set correctly by configure.
1160 --- 4.1.0 2010/10/05
1162 Solr Web Service support for yaz-client and ZOOM.
1164 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1166 --- 4.0.12 2010/08/17
1168 Z39.50 facet support. Facet specifications are passed for search in
1169 other-information with ASN.1 as defined in facet.asn and OID
1170 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1171 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1172 3 is limit (number of entries to get in response). yaz-ztest returns
1173 dummy facets if a client asks for them.
1175 --- 4.0.11 2010/07/09
1177 CCL fixes: bug 2895 and bug 3539.
1179 GR1-display: add comma in display - was removed by mistake in
1182 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1184 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1186 --- 4.0.10 2010/06/18
1188 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1189 result set from a connection. The result set will be on its own
1190 thereafter; no operations on it will perform retrievals from a target.
1191 Only cached copies are returned.
1193 ZOOM C:fix case for HTTP servers responding with Connection:close.
1194 Ensure that if there is a current task it is resumed (like fetching
1195 more records in a result set) . Bug #3484.
1197 PQF parser: use odr_atoi for Odr_int (not atoi)
1199 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1200 values that contain any non-digits are treated as string attributes
1201 (previously decoding only checked for leading character ([0-9]). PQF
1202 encoding: attribute string values are not surrounded by double-quotes.
1204 --- 4.0.9 2010/05/21
1206 New utility for managing threads - thread_create.h.
1208 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1209 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1210 but YAZ' implementation do.
1212 Fixes for yaz_cond-functions on Windows 7.
1214 DLL export more symbols.
1216 zoomsh: show record do NOT render opac.
1218 Remove *.la files from Debian and RPM packages.
1220 --- 4.0.8 2010/05/11
1222 Debian package libyaz-dev depends on libgnutls-dev again (was
1223 removed in YAZ 4.0.6, but due to Libtool it is still needed
1224 even though yaz-config do not list libgnutls libs).
1226 ZOOM: Use only one WRBUF for returning string results for
1227 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1229 ZOOM: ZOOM_connection do not use a shared pointer to
1230 ZOOM_resultset after ZOOM_resultset is destructed by
1231 user. Reverts to YAZ 4.0.4 behavior.
1233 --- 4.0.7 2010/05/04
1235 record-conv: fix problem with at least one XSL conversion -
1236 due to probably incorrect usage of XML XSL documents.
1238 --- 4.0.6 2010/04/29
1240 Fix yaz-config for static mode and the use of SSL (gnutls).
1242 --- 4.0.5 2010/04/29
1244 Forward decl timeval struct in mutex.h and gettimeofday.h.
1246 yaz-config: fix 'static' mode linking.
1248 --- 4.0.4 2010/04/28
1250 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1251 are wrappers for pthreads or Windows. For Windows these are put in
1252 a separate DLL: yaz_cond4.
1254 libyaz.la (whole source) is compiled with thread. If thread support
1255 is enabled enabled, all source of YAZ is compiled with treading support.
1256 This allows core utilities such as yaz_log to use thread facilities.
1257 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1258 thread utilities. This commit moves mutex utilities (mutex.c) from
1259 libyaz_server.la to libyaz.la.
1261 yaz-json-parse displays leading text until error.
1263 --- 4.0.3 2010/04/09
1265 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1266 patch from Giannis Kosmas.
1268 SRU: no longer URL encode SRU database. The URL for an SRU server is
1269 a URL and such is alreeady encoded - at least when given with leading
1270 http:// or https://. This reverts behavior to YAZ 3.0.50.
1272 Support for new MARC XML notation TurboMARC which like MARCXML is a
1273 complete representation of MARC/ISO2709.. This one, however, is more
1274 compact and allows for faster processing with XSLT. TurboMARC can be
1275 used in the marcdisp.h API, from the yaz-marcdump utility and from
1278 yaz-ztest can be configured - via the database - to perform certain
1279 delays when it performs operations search, present and single record
1280 fetch. This allows testers to make yaz-ztest act as a real or even slow
1281 Z39.50 server. Refer to the yaz-ztest man pages for details.
1283 --- 4.0.2 2010/03/09
1285 wrbuf_destroy allows NULL WRBUF passed to it.
1287 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1289 Add ZOOM_connection_close.
1291 No fixed size buffers for ZOOM shell - bug #3257.
1293 tstodr: make it work on s390 platform.
1295 New icu iterator-functions. The new icu_iter-functions makes it possible
1296 to use ICU chains from many threads.
1298 yaz-client: better syntax check for show command.
1300 --- 4.0.1 2010/01/26
1302 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1305 New simple local-file XML include facility which allows file glob-patterns.
1306 Refer to yaz/xml_include.h.
1308 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1311 ZOOM_record_get supports new parameter "format" which makes it format XML
1314 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1315 JSONText in ECMA-262) is JSONValue, not JSONObject.
1317 --- 4.0.0 2010/01/20
1319 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1320 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1322 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1323 POSIX/Unix builds .so with major version 4.
1325 Remove old LOG_-defines from log.h. They have been obsolete and
1326 undefined by default for the last 5 years.
1328 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1330 GFS: Remove socket (int *fd) from search_rr handler. The socket
1331 descriptor ptr is a facility that allowed a search handler to supply
1332 a socket which would serve as a callback - when search was complete.
1333 This facility has now been in use for years.
1335 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1336 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1337 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1338 returns 'const char *' rather than 'char *. The returned string is
1339 read-only and should not be modified by applications. COMSTACK cs_close is
1340 now a void function - it no longer returns int. No applications check for
1341 the value and the implementations has always returned 0.
1343 ZOOM: use size_t for scan hit counts and str size. Functions
1344 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1345 occ (hit count) and len (string length) are now of type size_t pointer
1346 rather than int pointer. This is to be able to represent large hit counts
1347 and to also just to use the proper type for string length (strlen result).
1349 New JSON parser. Refer to include/yaz/json.h .
1351 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1352 Used to be int in some cases. Many wrbuf_-functions used to return an int
1353 indicating some length.. These return values were never used. And so they
1356 ODR: odr_malloc, odr_total now takes size_t for size.
1358 clone_z_type: fix leak; occurred for encoding failures.
1360 --- 3.0.52 2009/12/03
1362 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1363 bug was introduced in 3.0.51.
1365 --- 3.0.51 2009/12/02
1367 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1369 tcpip comstack: fix leak for getaddrinfo.
1371 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1372 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1373 Decoding of SRU "path" database is performed by private function
1374 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1375 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1377 yaz-client: honor base command for SRU. Change when database setting
1378 is applied for SRU and ensure it is kept when a connection is reset.
1379 Change also the way errors are displayed or SRU (decoding of packages).
1381 --- 3.0.50 2009/11/02
1383 Add support for extra request / response data for SRU codecs and GFS.
1384 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1385 for extra data response buffer and length. For the GFS, both request
1386 and response data (XML) is carried in extra_args and extra_response_data
1387 for the search handler. Patch by Ko van der Sloot.
1389 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1390 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1391 10010). This fixes bug #2113.
1393 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1394 cmdfile included a 'quit' command that would result in a memory violation.
1396 --- 3.0.49 2009/10/01
1398 Make a number of functions defined in xmlquery.c static. These have
1399 never been declared in a public header file (yaz/xmlquery.h) and was
1400 made public by mistake.
1402 Improve speed of character conversions (iconv utilities). This makes
1403 conversions from MARC-8 faster.
1405 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1406 unless type desired is "raw". This will prevent type "xml" from
1407 returning ISO2709 .. Which obviously can not be XML parsed.
1409 Fix memory leak in ZOOM that would occur if option apdulog was used
1410 on a re-used connection.
1412 Frontend server logs HTTP requests.
1414 Frontend server now sends Z39.50 close when it times out (sesssion has
1415 been idle for too long). Versions 2.0.30 and earlier also sent close.
1416 But due to a mistake this was disabled in all versions after that, i.e.
1417 the server would just close the socket immediately.
1419 yaz-client emits a better message when receiving an unrecognised
1420 userInformationField.
1422 Skip zero-length subfields when decoding ISO2709. This rare case happens
1423 if a record has two FS characters in a sequence. Without this patch
1424 there would be a reference beyond char array in using_code_len fragments
1427 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1429 --- 3.0.48 2009/08/28
1431 The show command offered by the zoomsh command now takes a 3d optional
1432 parameter type which is what is passed to ZOOM_record. If the type
1433 argument is omitted, "render" is used.
1435 RPN to CQL conv may use USE string attributes (bug #2978).
1437 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1439 --- 3.0.47 2009/07/08
1441 Function yaz_xml2query allows a diagnostic element in the PQF XML
1442 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1443 code and additional info respectively.
1445 The BER BOOLEAN is now the integral type Odr_bool which still happens
1446 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1447 typedef'd to Odr_int. This is still an integral 'int', but it may be
1448 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1449 ASN-1 compiler as well as programs has been updated to use the new types.
1451 --- 3.0.46 2009/06/08
1453 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1454 only the bibliographic record was rendered. For type=opac, an OPAC
1455 record is only returned if it is present.
1457 iconv: small fix for encoding of advancegreek.
1459 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1461 yaz-client: option auto_reconnect=on really reconnects.
1463 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1465 server: avoid null ptr ref for for yaz_poll errors.
1467 build: fix RPM build for RHEL 5.3.
1469 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1471 --- 3.0.45 2009/03/31
1473 Fixed bug #2709: TCP connect returns Invalid argument.
1475 Fixed compilation for mingw.
1477 Honor charset for raw records (ZOOM_record_get).
1479 Fixed use of errno for threaded mode that was seen on Solaris 10.
1481 Fixed argument passing with blanks in value for Windows Service.
1483 Disable YAZ' own log rotate by default (no 1 GB limit).
1484 The variable l_max_size which specifies the log file limit is set to 0
1485 (DISABLED): This is due to the fact that YAZ is most often deployed using
1486 logrotate. Also YAZ can not perform log rotate because of unsufficient
1487 permissions (setuid).
1489 --- 3.0.44 2009/02/17
1491 List supported encodings in man page for yaz-iconv.
1493 Fixed missing SSL libs for --libs output
1495 Re-established OID record syntax application-xml. Nobody should use it
1496 but we don't want to change soname because of this symbol being absent.
1498 --- 3.0.42 2009/02/02
1500 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1502 Added member named_result_sets for init handler struct for the GFS. This
1503 allows a server to disable named result sets.
1505 Removed OID record syntax application-xml.
1507 Added support for rule-based transliterator for ICU wrapper of YAZ.
1509 Fixed bug #1902: yaz-icu XML output.
1511 Make YAZ checks Emacs friendly.
1513 BITSTRING value shows value. Bug #2346.
1515 ISO2709 decoding: skip control characters from indicator data.
1517 Omit sort key by default in yaz-icu's output.
1519 Allow combined single char options (again) for YAZ' options function.
1521 Utility yaz-marcdump got option to display YAZ version (-V).
1523 Allow YAZ to use ICU 3.4.
1525 Added new ICU test case which illustrates removal of diacritics.
1527 --- 3.0.41 2008/12/29
1529 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1531 --- 3.0.40 2008/12/29
1533 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1536 Fixed bug #2352: yaz-marcdump crashes for certain record.
1538 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1540 Added support for Danmarc2 to UTF-8 conversion.
1542 Added support for ISO5426 to UTF-8 conversion.
1544 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1545 implementation version.
1547 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1549 --- 3.0.38 2008/11/10
1551 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1552 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1554 ZOOM C now interprets databaseName option for ZOOM connection as path
1557 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1559 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1561 Dummy Libxml2 types no longer defined in headers of YAZ'.
1563 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1566 --- 3.0.36 2008/09/26
1568 Various ODR chapter fixes.
1570 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1572 Added missing source for Windows compilation, mutex.c.
1574 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1576 For SRU connections in ZOOM all records up to "count" are now fetched.
1578 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1579 in Windows due to bad error handling for Libxml2.
1581 Added facility for sending arbitrary records (ASN.1 any) using
1582 ZOOM C's Extended service update. Patch by Sam Reynolds.
1584 New options for ZOOM C's connection, logapdu which makes ZOOM log
1587 --- 3.0.34 2008/06/18
1589 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1591 --- 3.0.32 2008/06/12
1593 Fixed memory violation that could occur when decoding UTF-8. This bug
1594 was only present in 3.0.30 of YAZ.
1596 --- 3.0.30 2008/06/06
1598 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1599 GNU TLS is used by default (if found).
1601 yaz-ztest returns OPAC records if a client asks for OPAC.
1603 Improved speed of MARC-8 encoding.
1605 Added support for lossy and loss-less MARC-8 encoding.
1607 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1609 Added new Windows Service wrapper (sc).
1611 yaz-client's itemorder command may now send a file.
1613 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1615 Added new function yaz_log_xml_errors.
1617 Allow (but warn) unknown XML attributes in MARCXML parsing.
1619 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1621 The UTF-8 to MARC-8 conversion now uses a different set of characters
1622 for Greek symbols. Bug #2120.
1624 --- 3.0.26 2008/02/21
1626 Added yaz_daemon (daemon.h).
1628 Fixed bug #2068: pkg-config trouble
1630 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1632 --- 3.0.24 2008/01/28
1634 Document --with-xml2 option.
1636 Added OPAC XML XSD (etc/opacxml.xsd).
1638 Allow glob mask for name attribute in retrieval element for the
1639 generic frontend server's retrieval facility.
1641 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1642 except POLLIN/POLLOUT.
1644 Fixed error handling in cs_listen. Bug #2037.
1646 --- 3.0.22 2008/01/20
1648 Fixed version in yaz/yaz-version.h.
1650 Fixed bug #2027: Crash when closing connection.
1652 Changed configure so that ICU support is only enabled if only ICU
1653 and Libxml2 is available (because the ICU chain is XML based).
1655 --- 3.0.20 2008/01/15
1657 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1658 is built. Only this DLL depends on the ICU runtime.
1660 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1661 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1663 Changed license of CCL module to 'Revised BSD'. After consultation with
1664 remaining members of the original EUROPAGATE consortium, we are re-issuing
1665 the CCL module without a separate license. The software was developed by
1666 Index Data as part of a research project. The special license was included
1667 to help feed usage information back to the project consortium to support
1668 project evaluation. At this time, the project consortium has long-since
1669 disbanded, and the majority of the original principals have retired. At the
1670 same time, we have significantly modified the software during the following
1671 years, to the point where very practically no original code remains. To
1672 simplify re-use of the software, we have contacted those members of the
1673 consortium who could be reached, and agreed to re-issue the module as a
1674 proper part of the YAZ package.
1676 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1678 CQL closer to being version 1.2 compliant. CQL also allows free-form
1679 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1682 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1683 bug could make Extended services handling crash in the ZOOM layer. This
1684 bug was only present in YAZ 3.0.18.
1686 --- 3.0.18 2007/12/19
1688 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1691 yaz-marcdump reads and writes collection wrapped records.
1693 Handle OPAC for record conversion module.
1695 Fixes for ICU wrapper.
1697 Allow ICU libs to be controlled with --with-icu .
1699 --- 3.0.16 2007/11/12
1701 Added yaz_poll which is a wrapper for select/poll. When poll is available
1702 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1703 sockets to be in use.
1705 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1706 functionality through an XML based configuration (ICU chain). This system
1707 is useful for search facilities such as Pazpar2 and Zebra that needs to
1708 perform tokenization of indexed material. The ICU code in a separate
1709 library libyaz3_icu.a.
1711 Added HTTP tunnel facility for COMSTACK, bug #1752.
1712 This is a facility that allows a Web proxy, such as squid, to tunnel
1713 Z39.50 traffic. This facility is "transparent" to must applications
1714 using YAZ. It's enabled by using pseudo transport connect: followed by
1715 the proxy address, followed by command, then follwed by he regular
1716 "virtual" addresss. For example,
1717 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1719 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1721 --- 3.0.14 2007/09/21
1723 Fixed bad memory reference in ZOOM_record - cuased by member not being
1724 initialized. This was a problem only in YAZ 3.0.12.
1726 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1727 fields were not removed.
1729 Changed the way C code is generated from codetables.xml. Made a MARC-8
1730 conversion trie for each characterSet section rather than codeTable.
1731 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1732 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1734 --- 3.0.12 2007/09/12
1736 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1737 from ZOOM_record_error).
1739 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1741 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1743 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1745 Better SRW-to-Bib-1 diagnostic mapping.
1747 ZOOM C and yaz-client announces SRU version 1.2 by default.
1749 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1752 Fixed in yaz_sru_decode to allow other version than 1.1.
1754 --- 3.0.10 2007/08/22
1756 Added support for SRU scan for ZOOM.
1758 Added support for the use of the older versions or Extended Service
1759 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1760 set to the version , 1=first, 2=second, 3=third. The third version is
1761 what ZOOM C has used so far. And that, obviously, is the default.
1763 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1764 therefore in Zebra and in SimpleServer-based applications). The new
1765 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1766 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1767 which is passed into the back-end search callback function.
1769 Added support for HTTP Basic authentication in clients: the SRU/W
1770 codec encodes the username/password elements of the PDU structure
1771 appropriately, and these may be set using the "user" and "password"
1772 options in ZOOM-C applications (the same options that are used for
1773 Z39.50 authentication).
1775 --- 3.0.8 2007/06/25
1777 Fixed bug #1208: SSL appears to be broken in ZOOM.
1779 Fixed bug #1206: Libxml2 include path weirdness.
1781 Added oid_name_to_dotstring.
1783 Allow elementSetName to be specified for ZOOM C record update.
1785 Allow waitAction to be specified for ZOOM C based for Extended Services.
1787 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1788 syntax OID. Bug introduced in YAZ 3 series.
1790 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1792 --- 3.0.6 2007/06/06
1794 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1795 directory. yaz-client now reads commands from file given by option -f
1796 if specified; then tries to read .yazclientrc in current directory.
1797 Failing that, it reads .yazclientrc from user's home directory.
1799 Added support for correlationInfo Note and ID for Record Update via
1802 Added yaz-client command querycharset which specifies character set for
1803 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1804 (termListAndStartPoint).
1806 Charset ISO5428:1984 is an alias for ISO5428-1984.
1808 Implemented a way to perform scan in a result set using Z39.50. This
1809 is achieved by attaching the result set name in the characterInfo
1810 (type InternationalString) of OtherInformation in the Scan Request PDU.
1811 The result set is identified in the otherinformation by the new OID:
1812 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1813 This allows for scan in result set and faceted search . Zebra did some
1814 of this in the APT term using attribute type 8 and value being result
1815 set. Using the OtherInformation approach for this is cleaner and easier
1816 to work with in proxies and the like. This facility can be used in
1817 yaz-client using new command setscan which takes a result set as first
1818 argument, start position (APT) as second.
1820 Changed decoding of SRU XML packed records to deal with servers that
1821 have recordData with XML data with multiple root nodes. Also make
1822 comparison for recordPacking case insensitive. Again, one server
1823 returns "XML" where others return "xml".
1825 For SRU responses allow Content-Type application/xml as well as text/xml.
1827 --- 3.0.4 2007/05/21
1829 Fixed bug in character set conversion of BER strings. Bug introduced
1832 --- 3.0.2 2007/05/08
1834 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1836 For OID class, use oid_class consistently.
1838 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1841 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1842 character set for bibliographic information interchange". By Giannis Kosmas.
1844 Added documentation on new OID API.
1846 --- 3.0.0 2007/05/02
1848 Changes to generic frontend server interface: added new member
1849 'query_charset' for bend_initrequest structure. A backend init handler
1850 should set this member to its native character set for query terms.
1851 When defined, the frontend server logic will announce this character set
1852 to a client if the negotiationModel bit is set by the client. All server
1853 implementors are encouraged to specify this. If a backend server does not
1854 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1856 Added CCL utility to remove terms (stop words) from resulting RPN
1857 tree. This is handled by functions with prefix ccl_stop_words_ .
1859 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1860 terms in RPN queries.
1862 Clean-up the CCL API. Moved some internal structures from ccl.h to
1863 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1864 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1865 This is replaced by ccl_parser_find_str which takes a string instead.
1867 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1868 libyaz.la is the core of YAZ except the generic frontend server and
1869 does not depend on POSIX threads anymore. libyaz_server.la is the
1870 generic frontend server facilities and uses POSIX thread functionality
1871 if available. The libyaz.la no longer depends on POSIX threads because
1872 the number of global structures is limited. NMEM no longer re-uses blocks
1873 between threads ; it simply free's memory immediately but allocates in
1874 "large" chunks as usual. We don't expect any performance penalties
1875 because of this. The yaz_log system is still using a global log_level so
1876 caution must be taken when modifying it with yaz_log_init_.. +
1877 yaz_log_mask_str. This, however, should not cause any trouble because
1878 these functions are called during initialization of application code
1879 anyway. `yaz-config --libs server` returns libs for server applications;
1880 `yaz-config --libs` returns libs for non-server applications.
1882 New OID database - with public definitions in oid_db.h. Removed old OID
1883 database including the head oid.h and definitions such as enum oid_value
1884 and struct oident. The new OID database uses the same string names as
1885 before but the 'protocol' is gone. There are now only two representations
1886 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1887 converts from string to OID; functions with prefix yaz_oid_to_string
1888 converts the other way.
1890 Change to emit_term() in CQL-to-PQF query translation: when a term has
1891 the /regexp relation modifier, do not process it for leading and
1892 trailing "^" and "*", which have quite different meanings in regular
1895 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1896 write handlers no longer carries a 'last' parameter. This will make
1897 yaz_iconv flush "less" characters. A flush is performed by call to
1898 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1900 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1901 removed, because function yaz_query_to_wrbuf does the same.
1903 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1904 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1906 Deprecated MARC utility functions removed.
1908 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1911 Branch split: YAZ_2_1_55_branch
1913 --- 2.1.54 2007/03/16
1915 Fix to ZOOM-C so that transparent reconnection is properly handled on
1916 connections that are in asynchronous mode.
1918 Fixed compilation on OpenBSD 4.0.
1920 Large strings in GRS-1 records are now properly displayed in yaz-client.
1922 Added character conversion support for "advancegreek"; based on patch from
1925 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1926 sequence is met. Before the error was not set so it would be unknown.
1928 Adjust yaz-marcdump MARC reader so that it skips until record separator
1931 --- 2.1.52 2007/03/07
1933 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1934 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1935 fd_set structure used as a bitmask for the FDs to be selected on.
1937 Using ACX_PTHREAD macro to check for POSIX threads.
1939 Fixed have-vsnprintf check.
1941 --- 2.1.50 2007/02/23
1943 Fixes for configure on BSD. Bug #900.
1945 Added snprintf/vsnprintf wrappers for systems that don't have
1946 limits (heavens forbid).
1948 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1949 created before all previous tasks were completed and removed from the
1950 task queue, the new task could be removed by a mistake.
1952 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1954 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1956 Fixed bug #832: Problem with MARC/charset in yaz-client.
1958 Fixed bug #668: save command line history for yaz-client.
1960 Fixed bug #830: pkg-config support.
1962 --- 2.1.48 2007/01/23
1964 Extended ZOOM result set options with two options that may be read by
1965 a client: resultSetStatus and presentStatus with values as specified for
1967 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1969 Fixed bug #827: Using SSL fails on Debian etch.
1971 Fixed bug #826: Weird looking chars for set of MARC records.
1973 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1974 that is treated as an ItemOrder with itemRequest being an XML document
1975 external. The value of "doc" is the content.
1977 Extended the GFS search facility. New member of bend_search_rr
1978 'estimated_hit_count' signals that hits is known to be an estmate
1979 (higher or lower than real hit count). New member 'partial_resultset'
1980 signals that the search was partial (hit count is lower or equal than
1981 real hit count). For Z39.50, the information is stored in resultSetStatus
1982 member of SearchResponse APDU. For SRU, the information is signalled
1983 via SRU diagnostic 59: "Result set created with valid partial results
1986 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1988 --- 2.1.46 2007/01/13
1990 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1992 Added ZOOM_connection_peek_event.
1994 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1995 the following new functions:
1996 ZOOM_event_nonblock, ZOOM_connection_process,
1997 ZOOM_connection_get_{socket,mask,timeout},
1998 ZOOM_connection_fire_event_{timeout,socket}.
1999 The existing blocking event handler, ZOOM_event, is a wrapper for the
2000 + blocking ZOOM_event_sys_{poll,select}.
2002 Implemented function ccl_xml_config which parses XML version of CCL
2003 configuration (bug #798).
2005 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2007 Added timings utility (yaz/timing.h)
2009 --- 2.1.44 2007/01/03
2011 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2014 Fixed bug #779: Rotation of apdu.log fails.
2016 Fixed for character set conversions:
2017 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2018 Honor G1 set in MARC-8 decoding.
2020 --- 2.1.42 2006/12/17
2022 Fixed bug #775: char conversion does not handle Alternative UTF-8
2025 Implemented function yaz_marc_read_line which parses MARC line format
2026 records. There is a wealth of formats out there. So far, this function
2027 reads line records produced by yaz_marc_write_line.
2029 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2030 more generic and easier to remember(!) options: -i format and -o format
2031 which specifies input format and output format respectively - where
2032 format is one of "marc", "marcxml", "line", "marcxchange".
2034 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2035 does not print anything except warnings for records.
2037 For yaz-marcdump, added support for MARC split into files (-s) with a given
2040 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2041 spec, at http://www.loc.gov/standards/sru/record-update/
2042 This has changed the binary layout of the following structs:
2043 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2044 bend_update_rr . Patch by Ko van der Sloot.
2046 Added GFS utility function bend_assoc_is_alive which returns 1 if
2047 association is still alive (client is connected); 0 otherwise (client
2048 closed connection). This allows busy servers to stop working for
2051 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2052 been a separate piece of software. This version of ziffy has been modified
2053 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2055 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2057 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2058 Client code may now interrogate options such as "init_opt_sort" to
2059 find out whether the server claims to support various options.
2061 --- 2.1.40 2006/11/27
2063 Added utilities yaz_{set,get}_esn to set/get element set name from
2066 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2067 of YAZ and has been so since YAZ 2.1.10.
2069 Implemented ZOOM_record_error which returns error information for
2070 record (surrogate diagnostic).
2072 --- 2.1.38 2006/10/31
2074 Updates for SRU Update by Ko van der Sloot:
2075 1. Changed name from "operation" to "action"
2076 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2077 versions in the code, marked as 'backward compatible'.
2078 3. Added diagnostics for SRU Update.
2080 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2082 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2084 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2086 For GFS, fixed problem with SRU diagnostic 'First record position out of
2087 range' being issued for 0 hits.
2089 zoomtst10 part of Windows Build.
2091 --- 2.1.36 2006/10/13
2093 Implemented yaz_filepath_comp which splits a path into file path
2094 components (required by Zebra 2.0.3+).
2096 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2097 BSD inspired license until now so this should not have any real impact on
2098 anybody. See http://www.opensource.org/licenses/bsd-license.php
2100 Fixed bug #687: Missing log lines.
2102 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2105 Fixed bug #689: SRU diagnostics to be added.
2107 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2108 whether a connection is idle (no more work do do).
2110 --- 2.1.34 2006/10/04
2112 Change type of optval from long to int for invocation of setsockopt with
2113 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2115 Added support for specifying the max log file size for the Generic
2116 Frontend Server. The size is given with option -r.
2118 --- 2.1.32 2006/09/21
2120 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2122 --- 2.1.30 2006/09/17
2124 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2127 Fixed bug in Generic Frontend Server that could cause a server to stop
2128 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2130 For the generic frontend server, the maximum record size is used as maximum
2131 size of incoming packages (SRU + Z39.50). The value until was previously
2132 only used in Z39.50 Init negotiation and, later, in a session controlled
2133 sizes of records returned. This is controlled using -k option. It can be
2134 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2136 --- 2.1.28 2006/09/04
2138 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2141 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2143 New option for yaz-marcdump -lpos=value which allows setting a portion
2144 of MARC header to a certain value.
2146 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2148 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2149 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2151 --- 2.1.26 2006/08/15
2153 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2156 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2158 --- 2.1.24 2006/08/08
2160 Fixed MARC ISO2709 encoding routines to deal with character set
2163 Minor changes to GFS logging. Database included in search request log
2166 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2167 cached/multiple records.
2169 Shared libraries are built by default on Unix+configure.
2171 Changed cql2pqf transformation to use a different evaluation order. The
2172 new order is: always, relation, structure, position, truncation, index
2173 and relationModifier. Old order was: always, relation, relationModifier,
2174 structure, index, position, truncation. Note that the the latter ones
2175 override former ones for identical attributes.. The new scheme means that
2176 it is possible to override any existing attribute with a relationModifier.
2177 And also that it is possible to override everything for the index rule
2178 (except the ones listed in relationModifier). No order is perfect but this
2179 one, we believe, covers more real cases.. The "always" should have been
2180 called "default", since the attributes there can be overridden with all
2183 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2184 compilation phase, but also for yaz-config --cflags output. This allows
2185 us to have public headers with Libxml2 stuff in them . It should also,
2186 eventually, make Libxml2 checks redundant in packages using YAZ, such
2189 --- 2.1.22 2006/06/15
2191 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2192 stored in uri, message and details.. Previously diagnostics were stored
2193 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2194 compatibility.. but he's probably the only one affected, so.
2196 Added support for CCL, compiled on the client side, in ZOOM-C. This
2197 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2198 input; the resulting query objects can be used for for searching with
2199 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2201 YAZ' configure searches for OpenSSL by default.
2203 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2204 SL_CTX_use_certificate_file. See
2205 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2206 for more info. Thanks to Ko van der Sloot.
2208 --- 2.1.20 2006/06/02
2210 Bug #600: SRU GET, POST support for yaz-client. Introduced
2211 command 'sru' which selects method SOAP/GET/POST.
2213 Allow missingValueAction to be specified for the sortspec string -
2214 function yaz_sort_spec. By default, the missing value action is null.
2215 Use ! to specify "abort". Use = followed by stringvalue to specify default
2218 Ensured that Present-handler (if defined) is called in GFS before any call to
2219 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2220 searchRetrieve requests.
2222 Documentation for YAZ is now based on the Docbook XML/XSLT using
2223 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2224 is no longer depending on jade/openjade or docbook-to-man scripts.
2225 PDF is no longer part of the distribution - but can optionally be
2226 made using DSSSL/jadetex or FOP.
2228 Added retrieval handling support in Generic Frontend Server to support
2229 conversion between MARC/XML as well as XSLTtransforms. See
2230 etc/yazgfs.xml for an example.
2232 Added Authentication support to Generic Frontend Server in SRU
2233 mode. Authentication using HTTP Basic is supported, as is the use
2234 of 'x-username' and 'x-password' parameters in the request itself.
2236 Added support for a new character set MARC8s identical to MARC8 except
2237 that it converts combined characters to single Unicode characters in the
2238 Latin-1 range (when possible).
2240 --- 2.1.18 2006/04/24
2242 ASN.1 compiler 0.4: generates brief Doxygen file header for
2243 generated .h/.c files.
2245 Utility yaz_iconv now supports conversion to MARC-8.
2247 New facilities for the MARC module. The reading - and writing of
2248 content are separate methods for the yaz_marc_t handle. The following
2249 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2250 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2251 format). Write functions have prefix yaz_marc_write_.. The existing
2252 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2253 available. Removed support for OAI-MARC and simplexml (not the
2254 simplexml from PHP5).
2256 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2257 to be returned for this connection.
2259 --- 2.1.16 2006/03/31
2261 Allow multiple languages and charsets to be specified with
2262 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2263 negcharset iso-8859-1,utf-8
2265 Translation of proximity nodes from CQL into PQF now works.
2267 Moved to automake 1.8, 1.9.
2269 Added function yaz_log_set_handler which allows a log handler to be
2270 installed. This handler will be called for all log messages. Output
2271 to file is also produced; but that can be disabled by passing NULL
2272 fname to yaz_log_init_file.
2274 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2276 For SRW (including GFS), accept application/soap+xml as content-type
2279 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2280 produces NO stylesheet reference even if a default stylesheet is specified
2283 --- 2.1.14 2006/03/14
2285 Updated Windows package to include yazd.dll + yazd.lib for the
2286 Development component.
2288 If the environment variable YAZ_LOG is set, then it is used as a
2289 string indicating the default level of logging to use if not
2290 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2291 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2292 used as before. So, for example, to omit warnings from YAZ logging,
2293 export YAZ_LOG=-warn
2295 cql_transform() now map structure and other attributes before indexes,
2296 so that index-specific structures and other attributes can override
2297 defaults. So now a combination of mapping specifications such as:
2299 index.dc.date = 1=date-modified 4=5
2300 does the right thing.
2302 cql_transform() now also respects the "always" mapping specification,
2303 which establishes an initial set of attributes to be used for all
2304 terms except where overridden by more specific attributes associated
2305 with the index, relation or modifier.
2307 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2308 which mode to use; one of "post", "get" or "soap" (SRW, default).
2310 Fixes for yaz_iconv routines: changed trie-based character set conversions
2311 to use only non-negative values for bit fields due to Sun's C compiler not
2312 supporting negative values.
2314 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2315 sequences where not read correctly. Fix by Rustam Usmanov.
2317 Updated win/makefile to use options, settings which makes things
2318 compile with VS C 2005.
2320 --- 2.1.12 2006/02/01
2322 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2324 In ZOOM socket code, use select instead of poll on MacOSX.
2326 ZOOM-C now support client-side compilation of CQL into RPN that is
2327 sent to the server, enabling CQL to be used against all Z39.50
2328 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2329 ZOOM_query object, and submit it using ZOOM_connection_search().
2330 The CQL-to-RPN translation uses a configuration file, the name of
2331 which must be specified in the Connection's "cqlfile" option.
2333 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2334 function, which takes as its start-term parameter a ZOOM_query object
2335 (which may have had either CQL or RPN set into it).
2338 --- 2.1.10 2005/11/29
2340 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2341 GFS to support this as well. Backend handler, bend_srw_update, does the
2342 update work. Code contributed by Ko van der Sloot.
2344 Allow retrieval of Search Result-1 information in ZOOM by the use of
2345 options that are attached to a result set. ZOOM documentation updated
2348 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2349 UTF-8 conversion. Patch by Raj Patel.
2351 Added option -m to GFS to control formatting of timestamps in log file.
2353 Added 'exit' as synonym for 'quit' in yaz-client
2355 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2356 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2357 for the new members. Patch by Ko van der Sloot.
2359 Added support for SRU POST. It is supported for content-type
2360 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2362 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2363 Instead make the library libyaz.la multi-threaded. Threading as a whole
2364 can still be disabled by configure option --disable-threads. Previosly,
2365 with older GLIBCs there were problems with MT libs under Apache. This
2366 has now been fixed a long time ago.
2368 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2371 CQL module modified to be case insensitive for relations/indexes/operations.
2373 Fixed bug in CQL transform code: incorrect value relationModifieder
2376 Added 'show all' command for yaz-client which retrieves all results
2379 Added new yaz-client, xmles, which takes a (private) OID and
2380 a document to be sent as an extended service request.
2382 Describe new yaz-client commands wait_response and set_auto_wait.
2384 Increase TCP/IP listener backlog from 3 (which I am guessing was
2385 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2386 that the socket will queue as many incoming connections as it's able
2387 to handle ongoing connections. In other words, it will never now
2388 refuse a connection that it would be able to handle merely because
2389 it's not got around to accepting() enough of the pending connections
2390 yet. This is the behaviour anyway under Linux, where the listen()
2391 argument is ignored; but not under BSD and on systems such as
2392 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2393 YAZ-based servers should now be uniform across operating systems in
2396 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2397 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2398 This allows yaz-marcdump to read large MARC batches (>2 GB).
2400 Modified all YAZ source files - except the source which is auto-generated
2401 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2404 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2405 corresponding to the existing *_setl() function. These allow option
2406 values containing arbitrary valuues.
2408 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2409 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2410 except that it returns an indicator of whether or not the sort
2411 criterion was accepted (0 for OK, -1 for invalid).
2413 --- 2.1.8 2005/06/07
2415 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2416 MARC output rather than returning "new" buffer.
2418 yaz-client warns about unknown init options.
2420 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2422 --- 2.1.6 2005/05/24
2424 Added support for SRW sort in Generic Frontend Server. Patch
2425 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2426 sortKeys - or NULL if none is provided.
2428 Fixed bug #307: It was impossible to specify indefinite/no timeout
2429 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2432 Added support for multiple languages and charsets to be specified in
2433 ZOOM. Each charset/language is separated by a blank. If negotiation is
2434 in effect in init-response, Option
2435 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2436 Code based on patch by Vasiliy Osadchuk.
2438 Fixed bug #306: infinite recursion that occurred when calling
2439 yaz_log_level_init as the first call (before other log level or
2442 Fixed bug in scan handling in front end server: if preferred-Position-In-
2443 Response was non-present, a NULL pointer referece was performed.
2445 --- 2.1.4 2005/04/26
2447 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2448 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2449 now defined for all those error codes. So instead of putting 109 in
2450 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2451 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2453 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2456 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2458 Program yaz-client now exits and produces an error message if multiple
2459 Z39.50 servers are specified on the command line (none or one allowed
2462 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2465 --- 2.1.2 2005/03/16
2467 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2469 Fixed bug #272: Preserve spacing for CCL terms.
2471 --- 2.1.0 2005/03/14
2473 Added support for virtual hosts and multiple backend servers for
2474 the YAZ frontend server. The configution is XML based and
2475 support specificition of CQL to RPN mappings and explain information.
2476 See section "Virtual Hosts" in the YAZ manual.
2478 Extended OPAC display utility. OPAC display utility renders
2479 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2480 to supplement yaz_marc_decode_wrbuf.
2482 Fixed a bug in MARC decoder that could caused it to crash for some
2483 invalid MARC records. More diagnostics and warnings where added in
2484 XML output (warnings, etc are stored in comments).
2486 --- 2.0.34 2005/02/08
2488 Fixes for UNIX domain sockets. Bug #261.
2490 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2492 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2493 Added yaz_marc_subfield_str which defines subfield lead string which is
2494 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2495 yaz_marc_endline_str which defines end of fields string used in
2496 YAZ_MARC_LINE format. Default string is newline.
2498 Experimental support for MarcXChange. This format can be produced
2499 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2500 http://www.bs.dk/standards/MarcXchange.xsd
2502 Added yaz-client commands scansize that sets maximum number of
2503 entries to be returned by scan.
2505 --- 2.0.32 2005/01/11
2507 Added support for SRW scan in yaz-client and Generic Frontend Server.
2509 * Added whereInList member to SRW Scan Term.
2511 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2513 Fixed NMEM system to return aligned blocks on the smallest boundaries
2514 that are suitably aligned for all possible types on the particular
2515 architecture YAZ is being built for.
2517 --- 2.0.30 2005/01/04
2519 Fixed numerious warnings that was issued with newer versions of GCC.
2521 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2522 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2525 Make YAZ Generic Frontend Server slightly faster.
2527 Enhance (and reduce) logging for Generic Frontend Server.
2529 Revert YAZ log system so that it flushes every write operation
2530 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2532 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2533 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2534 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2535 will effectively disable old definitions.
2537 --- 2.0.28 2004/11/09
2539 Added yaz_log_time_format which specifies log format using
2542 Added yaz_log_module_level which returns mask for a module. Value
2543 is non-zero mask a if module is enabled; zero if disabled.
2545 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2546 in include/yaz/cql.h.
2548 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2550 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2552 Fixed bug #172: RPM builds does not enable SSL.
2554 Doxyfile.in part of dist. Doxyfile generated by configure.
2556 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2557 are given and the corresponding component does not exist.
2559 Extend CCL documentation in YAZ reference. Describe r=r.
2561 --- 2.0.26 2004/10/01
2563 Fixed MARC->MARCXML conversion to properly deal with
2564 fields, subfields, indicators having non-ASCII characters.
2566 Fixed MARC->MARCXML conversion so that ASCII control characters
2567 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2570 Added YAZ GFS support for conversion from Z39.50 surrogate
2571 diagnostics to SRW surrogate diagnostics.
2573 Bug fix: YAZ GFS did not return schema in explainResponse.
2575 --- 2.0.25 2004/09/30
2577 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2578 now converts recordSchema to elementSetName as well as schema URI.
2580 Fixed bug in COMSTACK that prevented HTTP request packages from being
2583 --- 2.0.24 2004/09/29
2585 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2586 does not require white-space before and after the dash in a range, e.g.
2587 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2590 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2591 due to new GCC removing "redundant" code.
2593 Added yaz-client commands scanpos and scanstep that sets preferred
2594 position and step-size for scan.
2596 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2598 Added CCL utility ccl_qual_buf which parses one or more CCL
2599 spec lines in a buffer.
2601 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2602 of name and value - ignoring empty lines and comments.
2604 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2606 Added odr_get_element_path which returns current element path for an
2607 ODR handle. This utility is useful in error handling or user-defined
2610 Added ODR_PRINT utility odr_set_stream which is is a more generic
2611 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2612 to a write function and pointer to close function. The close function - if
2613 non-NULL - will be called during odr_destroy.
2615 Fixed bug in CCL parser where truncation char was not removed from
2616 right side when truncation=both was in effect.
2618 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2621 --- 2.0.23 2004/08/11
2623 Fix buffer overrun in CQL parser when dealing with proximity (%).
2625 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2626 to UTF-8/UCS conversion is now only based on codetables.xml.
2628 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2630 --- 2.0.22 2004/08/06
2632 Add support for more "commit changes" in ZOOM (uses Extended Services).
2634 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2637 Yet another small fix for configure of SSL.
2639 --- 2.0.21 2004/05/14
2641 Fix SSL libs for configure when --with-openssl=DIR is given.
2643 --- 2.0.20 2004/05/10
2645 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2647 SSL comstack now uses yaz.pem certificate file on server side
2648 by default. Certificate filename can be configured by calling
2649 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2651 Fix bug regarding multiple calls to ZOOM_connection_connect.
2653 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2655 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2656 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2658 ZOOM now allows inspection of X509 peer certificate for verification.
2659 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2661 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2662 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2663 as "modular" but it simplifies things.
2665 Added cs_get_peer_certificate to that returns peer X509 PEM.
2667 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2668 NULL if SSL is unavailable.
2670 Documentation about MARC decoding tools.
2672 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2674 --- 2.0.19 2004/03/30
2676 Rename CHANGELOG to NEWS to follow GNU style packing.
2678 Fix bug with missing initialization of member in init_diagnostics.
2679 This bug affects threaded version of GFS server.
2681 --- 2.0.18 2004/03/20
2683 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2686 Ensure zlib.dll is packed with Windows install.
2688 --- 2.0.17 2004/03/17
2690 Fix encoding of xsd:string to use text instead of CDATA.
2692 Fix endless loop in CQL parser with unbalanced ".
2694 Use a more compact way to store MARC-8 conversion tables.
2696 --- 2.0.16 2004/03/16 Debian only
2698 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2701 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2706 --- 2.0.15 2004/03/01
2708 Another fix for decoding of XML packed records.
2710 --- 2.0.14 2004/02/25
2712 Fixes for Chunked encoding. White space not ignored after length spec.
2714 Update NS and use default NS for SRW diagnostic elements.
2716 --- 2.0.13 2004/02/23
2718 Implement ZOOM_resultset_cache_reset which resets record cache.
2720 Implement ZOOM_resultset_sort which sorts a result set.
2722 Implement chunked HTTP transfer.
2724 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2726 --- 2.0.12 2004/02/16
2728 Added member 'schema' to bend_explain_rr structure so that backend
2729 can specify explain record identifier. Defaults to Zeerex 2.0.
2731 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2733 --- 2.0.11 2004/02/16
2735 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2738 Added init command for yaz-client which sends "extra" init request.
2740 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2741 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2743 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2745 Make ZOOM error code for "invalid query".
2747 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2749 --- 2.0.10 2004/02/05
2751 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2754 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2756 Added option -p <file> to make Generic Frontend Server to write PID file.
2758 Added option -D to put Generic Frontend Server in background on its own.
2760 Make ZOOM C recognize option "password". If unset, "pass" is used
2761 (for backwards compatibility).
2763 Fixed a bug in Generic Frontend Server that could make it crash if a
2764 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2767 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2768 Must be issued before open, in order to be in effect.
2770 --- 2.0.9-6 2004/01/12 Debian/Windows
2772 Make the SRU server more picky WRT unknown params, etc.
2774 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2776 New YAZ client command, options, that sets Z39.50 options.
2778 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2779 options from a string of tokens (one token for each option bit).
2781 Update SRW diagnostic code messages.
2783 --- 2.0.9-5 2004/01/07 Debian/Windows
2785 Handle user defined stylesheet for SRW/SRU.
2787 --- 2.0.9-4 2004/01/06 Debian/Windows
2789 Fix bug in decoding of Content-Length.
2791 --- 2.0.9-3 2004/01/06 Debian/Windows
2793 Fix a bug with decoding of XML packed records.
2795 --- 2.0.9-2 2004/01/05 Debian only
2797 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2799 Fix bug in SRW/SRU diagnostics decoding.
2801 --- 2.0.9 2004/01/05
2803 Fixed bug in Generic Frontend Server which could drop records exceeding
2804 preferred message size. Reported and fixed by Irina Dijour.
2806 Fixed calculation of package size for structured records in Generic
2807 Frontend Server. Reported and fixed by Irina Dijour.
2809 Fixed namespace for SRW/SRU diagnostics.
2811 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2813 --- 2.0.8 2003/12/22
2815 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2816 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2819 CQL changes to reflect recent changes to the specification:
2820 * Documentation talks about context sets instead of index sets.
2821 * Documentation talks about indexes instead of qualifiers.
2822 * The CQL-to-PQF transformer's configuration file now uses
2823 "index.set.name = <attributes>" instead of the old form
2824 "qualifier.set.name = <attributes>". (Both forms are still
2825 understood but the latter is deprecated.)
2826 * CQL terms with no explicit index specified are now interpreted as
2827 cql.serverChoice instead of srw.serverChoice (which of course
2828 behaves exactly the same.)
2830 --- 2.0.7 2003/12/16
2832 MARC conversion can now generate ISO2709 output in another
2833 character set. yaz-marcdump uses this facility if you invoke it
2836 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2837 functions from there can be used from C++.
2839 --- 2.0.6 2003/12/04
2841 Frontend server now transfers memory from decoded packages to stream
2844 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2845 references to show up.
2847 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2848 the ZOOM Abstract API. The older names for the same options are still
2849 also supported for the benefit of old applications.
2851 ZOOM-C supports "implementationId" and "implementationVersion" options
2852 to go along with "implementationName". These allow the user code to
2853 specify identification strings to be sent to servers.
2854 Add OID for the new ExtLite attribute set.
2856 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2857 as requested/supplid by Ere Maijala <ere@atp.fi>
2859 For generic frontend server, reverse the order of
2860 "toolkit-supplied / application-supplied" strings sent as implementationId,
2861 Name and Version. Also, remove the spaces around the slash. This brings
2862 the GFS in line with the behaviour of ZOOM-C on the client side.
2864 Add function ZOOM_scanset_display_term.
2866 yaz-client shows scan displayTerm if present.
2868 Utility yaz-iconv is now installed by default along with the man page
2871 Extend configure check for OpenSSL to use pkg-config where available (such
2874 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2875 server to specify uid/gid/mask for socket using the format
2876 unix:[user=uid,][group=gid,][umask=mask,]file=path
2877 If file= is omitted the existing format is assumed, e.g.
2879 in which case the mask is 0666 (rw for everybody).
2881 Major restructure of YAZ source. All source in libyaz is in src directory.
2882 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2883 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2885 Added man page for utility yaz-marcdump (used to be called marcdump).
2886 yaz-marcdump is installed by 'make install'.
2888 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2889 of incoming package failed.
2891 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2893 Change prototype of odr_perror: add const to message string.
2895 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2897 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2898 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2899 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2900 DNS lookup. There should not be any compatibility problems with this
2901 assuming that blocking=1 or 0 is used.
2903 Fix bad reference in UNIX comstack in function cs_addrstr.
2905 Fix for compilation on AIX.
2907 The generic front-end server (server/seshigh.c) now supports returning
2908 Init diagnostics to the client in User-information-field, in
2909 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2912 --- 2.0.4 2003/09/04
2914 Allow any CQL relation (not just all,any,exact,scr).
2916 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2917 that features the same UI.
2919 Implemented command update0 in YAZ client which is equivalent to
2920 update but uses old of Ext Update ASN.1.
2922 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2923 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2924 Previously no OID was used for this info.
2926 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2927 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2928 returns 'malformed search term' otherwise.
2930 SortResponse member resultCount now set to NULL in sort handler of
2933 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2936 Add three new utility functions for translating OIDs between various
2937 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2938 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2939 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2940 char *oid_to_dotstring(const int *oid, char *oidbuf);
2941 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2943 Reverted modifications for ES Update definition for z_IU0Update
2944 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2945 is back to YAZ 2.0.2.
2947 String value attributes for CCL parser.
2949 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2950 which their FirstSearch server returns in Init responses, sometimes
2951 carrying useful diagnostic information when Init fails. This has the
2952 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2953 "z39.50/oclcui.asn", where its definition is somewhat different from
2954 what OCLC document on their web-site, as required to interoperate with
2957 Support for anonymous authentication in yaz-client. Use the command
2960 * Fix the OID of the Index Data-local "admin" Extended Service from
2961 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2962 the 1000, which indicates a locally-defined OID, was a mistake.
2964 --- 2.0.3 2003/06/20
2966 Fix CCL directive @case handling so that it affects string match for
2967 both CCL keywords and qualifiers.
2969 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2970 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2971 Decoder has been updated with ASN.1 changes as listed in
2972 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2973 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2974 z_IUUpdate, remains unchanged.
2976 ZOOM_record_get may now return a record in a specific character set.
2977 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2978 "from" is the character set of record as returned by target. "to" is
2979 the character set to be returned. If omitted, "to" is UTF-8.
2981 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2983 New ODR utility, odr_getelement, which returns name of element for
2984 which encoding/decoding failed.
2986 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2987 in cases where a required element was omitted.
2989 Bug fix: some MARC8 sequences were not converted.
2991 New ZOOM option "step" which specifies number of records to be
2992 retrieved in one chunk. Used in conjunction with "start" and "count".
2994 SRW support for yaz-client. Use scheme http: to use it, e.g.
2997 yaz-client no longer does (un)intelligent character set conversions
2998 by default. Can be enabled with charset and marc_charset commands.
3000 xmalloc trace fix for 64-bit systems such as DEC alpha.
3002 Solaris 2.6 compile fix.
3004 New function, cql_strerror() translates SRW error codes, as returned
3005 by cql_transform_error(), into human-readable English strings. Used
3006 in yaz-client diagnostics when appropriate.
3008 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3009 converts it into a type-1 query which is sent to the server. This
3010 makes CQL available for use with all Z-servers, as opposed to the tiny
3011 minority that can handle CQL queries themselves.
3013 --- 2.0.2 2003/04/28
3015 New Debian package layout similar to the Redhat Package layout.
3017 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3018 and search result respectively.
3020 --- 2.0.1 2003/04/25
3022 Redhat package is now several packages: libyaz (runtime libraries),
3023 libyaz-devel (development and documentation, and yaz (utility programs).
3024 Package spec file by Morten Bogeskov.
3026 New member 'schema' in struct bend_fetch_rr which the name of requested
3027 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3028 handler MAY set this to reflect the schema of the returned record.
3030 New member 'display_term' in struct scan_entry. GFS now sets member entries
3031 and allocates scan entries to be filled by user scan handler. In previous
3032 version, entries member was allocated by the scan handler. That still works,
3033 but the GFS will ignore member display_term - assuming it was NOT set by
3034 the handler. The fact that the GFS now allocates the entries both allows
3035 for new members and makes a scan handler easier to write.
3037 Fix CQL lex buffer overflow.
3039 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3040 SRU default recordPacking is string.
3042 SRU protocol support for frontend server.
3044 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3046 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3048 Added scan for the ZOOM shell (zoomsh).
3052 * String Identifers for Schemas (Amendment 5).
3053 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3054 Old definition for schema
3055 Odr_oid *schema; /* OPT */
3060 Z_InternationalString *uri;
3061 #define Z_Schema_oid 1
3062 #define Z_Schema_uri 2
3065 * resultCount parameter to Sort Response (Amendment 1).
3066 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3068 Support for SRW 1.0 over HTTP. This is an optional feature and
3069 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3072 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3073 on the same port. SRW SearchRetrieveRequests are mapped
3074 to bend_init,bend_search,bend_fetch,bend_close.
3076 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3078 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3079 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3081 ZOOM connections are SRW based if schem http is used for hostname
3082 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3083 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3085 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3086 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3087 distance=n, order=true/false, relation=le, prox unit=word. If
3088 n is omitted, distance 1 is used.
3090 Fixed problem with C compiler include path in wrong order.
3092 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3093 on Solaris. Patch from Ko van der Sloot.
3095 New MARC decode API. All new functions operate on a yaz_marc_t
3096 handle. The most important new functions are: yaz_marc_create,
3097 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3098 decode and destroy respectively. Decoder can produce formats
3099 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3100 include/yaz/marcdisp.h.
3102 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3103 to UTF-8, UCS-32, wchar_t or Latin-1.
3105 * Prototypes for yaz_iconv_-functions moved to separate header
3106 include/yaz/yaz-iconv.h.
3108 Make a few private functions 'static' in unix.c. This prevents
3109 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3111 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3112 are set when Init Response is received.
3114 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3115 but returns diagnostic set as well.
3117 New function yaz_strerror which is a portable wrapper for
3118 strerror/strerror_r/GetLastMessage.
3120 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3121 is returned for MARC. If type is "oai", then OAI MARC is returned.
3123 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3126 --- 1.9.2 2002/11/26
3128 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3130 Fix bad race conditions on SIGTERM and terminate gracefully in
3133 Move retrieval (data1) module to Zebra since nobody seems to be
3136 Add GRS-1 render for ZOOM using same format as yaz-client.
3138 --- 1.9.1 2002/10/05
3140 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3142 Fix broken ESpec handling in data1 module.
3144 SGML reader parses comments and makes them part of the data1 tree.
3146 Added several type casts so that YAZ compiles as C++ code.
3148 ZOOM didn't handle PDU encoding failures properly.
3150 Added more Bib-1 diagnostics (approved extensions).
3152 GNU configure: better check for iconv.
3154 More portable use of accept, getpeername. Check for socklen_t. Use
3155 int/size_t if socklen_t is not defined.
3159 PQF parser rejects bad queries - including those with extra
3160 characters in them. PQF parser used to silently ignore that.
3161 Cleaner API for PQF added, which allows you to get detailed
3162 error information for bad queries (see yaz/pquery.h).
3164 Fixed bug in ZOOM_record_get for type "database".
3166 Implemented mini iconv library supporting conversions between
3167 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3169 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3171 --- 1.8.9 2002/08/20
3173 Fixed ZOOM C record cache so that preferredRecordSyntax and
3174 elementSetName is used to check for already fetched records.
3176 --- 1.8.8 2002/08/02
3178 Added three members in bend_initrequest structure to facilitate
3179 character set negotiation.
3181 Fixed a bug in frontend server that could cause indefinite
3182 loops under rare conditions.
3184 Revised character set utilities (charneg.h) so that encoding
3185 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3187 For PQF, directive @term <type> sets term type for Scan/Search.
3188 Here <type> is general, string, numeric, null. The term type
3189 is inherited - just like @attr.
3191 New call odr_set_charset that sets character set conversion for
3192 international-strings on a ODR stream. Prototype is:
3193 int odr_set_charset(ODR o, const char *to, const char *from);
3194 The InternationalString is still represented as C string in YAZ
3195 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3196 won't). On the protocol level, you can use any encoding.
3198 Support for UNIX sockets in ZOOM.
3200 Solaris recv sometimes returns errno == ENOENT. It is treated as
3201 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3203 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3204 both client and server. Code by Morten Bogeskov.
3206 --- 1.8.7 2002/05/22
3208 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3209 that they can be used directly from Visual Basic. You must recompile
3210 your windows APP if you're using ZOOM.
3212 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3213 Commands "lang" and "charset" sets language and character set respectively.
3214 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3215 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3217 Attributes from multiple CCL fields may be OR'ed rather than merged
3218 using directive "@field or". Fields are still merged by default -
3219 equivalent to "@field merge".
3221 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3224 Fixed bug in zget for parameter ExtendedServicesResponse.
3228 --- 1.8.6 2002/03/25
3230 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3232 Client displays USR.1:SearchResult-1 (hits per term).
3234 Additional Search Info for search in Generic Frontend Server.
3236 Fixed CCL parsing of "field=s".
3238 WIN32 installer - using the excellent NSIS software from nullsoft.
3240 Fixed CCL parsing of "field = - <number>".
3242 Added function yaz_marc_decode that decodes MARC for line mode
3243 display or XML (similar to that used by JZKit).
3245 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3246 Z39.50. But ISO/ILL was, however.
3248 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3249 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

3252 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3254 --- 1.8.5 2002/02/03
3256 New YAZ client features: Command completion and new commands:
3257 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3258 Code provided by Jacob Poulsen.
3260 New call oid_trav, that visits all registered OIDs via callback.
3262 Function ZOOM_record_get now returns const char pointer rather than
3263 void pointer. It saves a lot of type casts.
3265 For YAZ client, command "auth" now allows you to set authentication
3266 in IdPass style. It is enabled when three tokens are given - order
3267 is user, group and password.
3269 Fix memory leaks in MARC record handling for ZOOM.
3271 New option for YAZ client, -k <kilobytes> that sets
3272 maximum record size. Similar to -k option for generic frontend
3273 server and yaz-ztest.
3275 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3277 Prefix query parser reports "fail" when bad attribute set is given.
3279 Fix in MARC decoder. Proximity logging. Fix for attribute set
3280 in scan handler for server. Patches by Shigeru Ishida.
3282 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3285 Configure option --with-openssl=<dir> now works when a directory is
3286 specified. Patch provided by Morten Bogeskov.
3288 New option for YAZ client, -u <auth>, that sets authentication.
3290 ZOOM fix: error information was sometimes "missing", since error
3291 was cleared/reset too when it shouldn't.
3293 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3295 --- 1.8.4 2002/01/04
3297 Scan for ZOOM API. New object ZOOM_scanset. New functions
3298 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3299 ZOOM_scanset_destroy.
3301 New ZOOM function, ZOOM_connection_last_event, that returns type
3302 of last event (such as "receive data", "send data", "apdu received",
3305 New ZOOM option, schema, that specifies schema for retrieval.
3307 New CCL feature. Qualifiers can be aliases for one or more
3308 other qualifiers (if more than one is given, OR is used).
3310 ZOOM uses named result sets if target supports it.
3312 Two new YAZ client commands: . (dot, which sources a script of YAZ
3313 client commands), and ! (to execute shell command.). Implemented
3316 Working on Debian packages.
3318 --- 1.8.3 2001/11/19
3320 YAZ client enables named result sets only if target supports it.
3322 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3324 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3325 with key="host" to get same result.
3327 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3328 Function Z3950_resultset_record(s) returns references to records
3329 "owned" by resultset. To become owner use Z3950_record_clone.
3331 Function z_ext_record handles Extended Services. Thanks to
3334 --- 1.8.2 2001/11/12
3336 CCL Parser fix: ignore token comma when dealing with and-lists.
3338 Documentation updates for COMSTACK.
3340 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3341 Changed prototype Z3950_records. For some functions, int parameters
3342 were changed to size_t.
3344 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3347 New MARC decode/display function, marc_display_exl, which properly rejects
3348 non-ISO2709 records. YAZ client uses it.
3350 --- 1.8.1 2001/10/29
3352 Fix bug: local attribute set wasn't set correctly in PQF strings.
3356 * Old Z39.50 codecs no longer supported.
3358 Added ZOOM C binding. See http://zoom.z3950.org/
3360 Renamed states for COMSTACKs to avoid confusion with events.
3362 Implemented cs_look and proper cs_rcvconnect.
3364 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3366 Configure detects POSIX threads on OpenBSD.
3368 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3369 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3371 When error is returned from present handler, non-surrogate diagnostic
3372 is returned in present response (and fetch handler is no longer called).
3374 * Minor adjustments to pquery parser (PQF). Token characters may be
3375 escaped by using backslash (C-style).
3377 PQF parser allows string attribute values to be specified. For @attr,
3378 non-numeric characters after the equal-sign are treated as strings
3379 (e.g. @attr 9=title).
3381 CCL trunction character may be defined (@truncation in file)
3383 * function zget_ExtendedServicesRequest sets waitAction to
3384 waitIfPossible (was wait).
3386 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3389 CCL operator names may be set in field definition files (CCL_bibset).
3390 See ccl/bib1 for an example.
3392 Fixes in ASN.1 compiler for C++ compatibility.
3394 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3395 and "op_or" to avoid conflict with C++.
3397 Fixed problem with GNU readline detection on Redhat 7.0.
3399 Added step-size for Scan backend handler.
3401 Fixed bug that made the frontend server crash when no attribute
3402 set was specified for scan.
3404 Front-end server automatically switches to original working directory
3405 when installed as an NT service. Previously -w had to be specified to
3408 Added extended attributes for retrieval module (data1), so that data1
3409 records carry d1_readXML/SGML attributes. d1_read also supports
3410 null-data rules ( <tag/>)
3412 On UNIX when POSIX threads are available, a separate library libyazthread
3413 is created. Programmers should link with that library and the yaz library
3414 when using threads. The reason for the split was that some applications
3415 on Linux, such as Apache, doesn't work well when using shared objects that
3418 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3419 (or any frontend server) in SSL mode by specifying ssl: followed by
3420 address. Only tested on UNIX.
3422 Added feature for CCL module. Virtual structure s=al or s=ol generates
3423 and-list and or-list respectively instead of phrase search.
3427 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3428 log_mask_str. This was done to avoid name conflicts with other libraries
3429 (such as other PHP extensions).
3431 Added raw OID member for preferred record syntax (request_format_raw)
3432 and returned record syntax (output_format_raw) for backend fetch method.
3434 Config file yaz-config now accepts options so that it returns specific
3435 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3437 Shared library support for UNIX using GNU libtool.
3439 * Modified backend interface. Request/Response struct's replaced by
3440 one read/write C struct. For example bend_fetchrequest and
3441 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3442 Every handler - even search has to be registered in bend_init
3443 handler. This means that the YAZ library no longer refers to
3444 external functions and it makes it possible to make the whole
3445 thing a single DLL/SO.
3447 Added Segment handler for backend server.
3449 Added Zmbol/Zebra administrative functions to YAZ client.
3451 Threaded frontend server on UNIX (when POSIX Threads are available).
3452 Starting the server with option -T enables multi-threading.
3456 Added configure option --enable-comp/disable-comp to control use
3457 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3458 located in sub directory asn.
3460 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3461 in ${exec_prefix}/bin along with the other programs yaz-client and
3464 GNU automake used to maintain makefiles.
3466 Added several OID's.
3468 Changed retrieval module so that we can load records with no abstract
3469 syntax defined. Tagpaths in these records are fully composed of string
3472 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3476 On UNIX, the generated makefile now supports a proper 'make install'.
3477 The prefix can be set via GNU configure to set the install location
3478 (default is /usr/local).
3480 * YAZ programs client and ztest were renamed to yaz-client and
3481 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3482 locations, such as /usr/bin,/usr/local/bin,etc.
3484 * YAZ Header files were moved from include to include/yaz. YAZ Header
3485 files are referred to as include <yaz/log.h> rather than <log.h>.
3486 The YAZ include path (-I ..) is therefore the same as before. Programmers
3487 should update their #include statements or use -Ipath/include/yaz
3488 instead. The main motivation for doing this change is that YAZ header files
3489 can be installed in "standard" locations /usr/include,/usr/local/include
3490 without introducing conflicts, since ALL YAZ header files are stored
3491 in subdirectory yaz (under /usr/include for example).
3493 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3494 rather than project/workspace files. We switched because project files
3495 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3498 Changed name of logging function, logf, to yaz_log, to prevent name
3499 clash with some math-log functions. The YAZ header log.h defines logf
3500 to yaz_log (#define) so there should be no incompatibilities by this
3503 Added bend_start/bend_stop handlers for server. These handler are
3504 called on start/stop of server. For windows they are called whenever
3505 a service is started/stopped.
3507 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3508 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3509 in util/yc.tcl. The auto-generated C code structures are, in a few
3510 cases, incompatible with the old decoders. There are differences in the
3511 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3512 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3513 The preprocessor variable ASN_COMPILED is defined when the compiled
3514 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3515 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3516 wish to use the old encoders/decoders you can specify --disable-yc
3519 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3520 version so that it supports both new - and old version of DB Update
3522 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3523 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3524 change. The name parameter can be set to 0 in which no name is specified
3525 for the construction. The macros odr_implicit and odr_explicit sets name
3526 parameter to zero for the construction involved. New macros
3527 odr_implicit_tag and odr_explicit_tag are similar to the others,
3528 except that a name parameter is added. For programmers' that don't use
3529 ODR they probably only need to change the call to z_APDU and z_External.
3531 Added access control facility by interfacing the TCP wrapper library.
3532 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3533 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3534 name of the daemon and enables the access control as specified in
3535 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3537 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3538 den Dool <H.M.vdnDool@kub.nl>.
3540 Added reference ID parameter to most functions in server API - refer
3541 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3543 Changed name of ccl library to libccl.a (was ccl.a).
3545 Fixed bug in decoder for Explain (Category TargetInfo).
3547 Added support for GNU readline in client. Thanks to Jacob Poulsen
3548 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3550 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3551 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3552 IMPLEMENTATION! This change was made to the development version before
3553 the ZIG decided to retract the amendment. If any users MUST be
3554 compatible with the original Update definition, PLEASE CONTACT US, and
3555 we will include a separate definition corresponding to the old Update
3556 ES. Note that because of the change to the ASN.1 of the
3557 TaskPackageRecordStructure we cannot define a single structure that
3558 will support both versions.
3560 * Added const modifier to buffer parameter for some ODR/BER encoding
3561 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3562 completeWAIS, odr_dumpBER.
3564 Fixed bug in client.c which caused a crash when a scanResponse didn't
3565 contain positionOfTerm.
3567 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3568 * will cause an error in a client if a non-YAZ target sends both a
3569 * list of Scan entries and non-surrogate diagnostics.
3571 Retrieval module enhancements. Tag sets may be typed in the reference
3572 to it. From the .abs-file the "tagset" directive takes a third optional
3573 integer type for the tag set referenced. From a .tag-file the "include"
3574 directive takes a third optional type as well. The old "type" directive
3575 in the tag set itself is still recognized but acts as the default type
3578 Backend interface change. Individual Scan terms returned from bend_scan
3579 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3580 in include/backend.h.
3582 Retrieval module enhancements. Multiple tag sets and attribute sets may
3583 be specified in abstract syntax specs. Revised the error/warning for
3584 logging messages reported by the retrieval module when reading the
3587 Object Identifier system (oid_..) changed. The API is backwards
3588 compatible but the oid-routines now allocates new OID's when needed.
3589 Raw OID's may be specified in oid_getvalbyname.
3591 YAZ now uses GNU configure to generate Makefile(s).
3593 * Minor changes in some of the member names of DeleteResultSetRequest and
3594 DeleteResultSetResponse. See include/proto.h.
3596 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3597 and added member 'languages' in TargetInfo (which was missing).
3599 Changed the way attribute sets are handled in the retrieval
3600 module. These are now cached, just like the abstract syntaxes
3603 Changed YAZ so that it links with compiled ASN.1.
3605 Added Explain-schema definitions and mapping routines. The following
3606 Explain categories have been implemented: AttributeDetails,
3607 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3609 Fixed minor bug in Windows version of Server Library.
3611 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3613 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3615 Added EXTERNAL: UNIverse Resource Report (non-standard).
3617 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3618 ENUMERATED and SET OF.
3620 * Added 'const' to some of the char pointer arguments for the
3621 functions, data1_read_node, data1_getelementbytagname,
3622 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3625 Fixed bug in data1_insert_taggeddata - the last_child member of
3626 parent wasn't initialised.
3628 * Changed data1_read_record and data1_read_node so that the supplied
3629 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3630 doesn't refer to any parts of the "SGML"-buffer.
3632 Fixed bug in server library (Windows version of statserv_remove).
3634 * Changed code so that it compiles as C++. The type definition
3635 of Odr_fun which is a member of Odr_arm was changed. The result is,
3636 that an explicit typecast is needed for the fun pointer when
3637 using Odr_arm - as in:
3638 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3640 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3642 Implemented the new structured date and time definition as approved
3643 by the ZIG. Added schemaId element to the specificTag in Espec-1
3644 (also approved at the last ZIG). Thanks to RVDM.
3646 Added some Object identifiers (RVDM).
3648 Changed the Update Extended Service (RVDM).
3650 Added command "refid" to client which specifies referenceId for
3651 the following requests.
3653 Implemented extended service handling for server. See ztest.c
3654 for an example as well as backend.h. New handlers are registerd
3655 in the Init handler.
3657 * Changed interface for sort in server.
3659 Added new members to statserv_options_block. It allows a server
3660 to read options from another source than just the command line. Thanks
3661 to Charles Woodfield.
3663 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3664 renamed to zboolean. Some C++ compilers complained about the name.
3666 Minor changes to gils.abs. Added index 's' (sort) on title
3667 and date/time-last-modified.
3669 --- 1.4pl2 1998/1/30
3671 Fixed bug in server library regarding inetd mode (-i). This bug
3672 was introduced by release 1.4.
3674 --- 1.4pl1 1998/1/29
3676 Added sort facility in client and backend server interface.
3678 Fixed problem with dependencies in Makefile(s).
3680 Fixed bugs for encoders/decoders of extended services and
3683 Implemented sub-tree feature for schemas. Sub-trees are
3684 referenced in *.abs-files. See explain.abs for an example
3685 of the use of this feature.
3687 Modified bib1.att; local attributes for ANY didn't include
3688 ANY itself (only affects use of the retrieval module).
3690 Fixed bug in plain SGML reader in function data1_read_node:
3691 tags with prefix "var" was incorrectly interpreted as variants.
3693 Added feature "sub-schemas" to enable references to - and definitions
3694 of - group of elements.
3696 * Removed member parent from type data1_element (in data1.h).
3698 Implemented function odr_nullval() that returns the value of
3701 * Removed member num_children from data1_node (in data1.h).
3703 Made NT service interface part of the server library. The
3704 function statserv_main uses the NT service when required and
3705 calls the statserv_start / statserv_close routines.
3707 Routine zget_SearchRequest and zget_PresentRequest fills
3708 resultSetName/Id member with "default" instead of "Default".
3710 Fixed memory leak in server. Request queue member wasn't freed.
3712 Fixed nmem_exit so that memory is freed.
3716 Revised the CCL parser utility to be thread safe.
3718 Added function, oid_ent_to_oid, to replace the function
3719 oid_getoidbyent, which is not thread safe.
3721 * Added nmem_init and nmem_exit to initialize and release
3722 NMEM resources. Function nmem_init should be called once in the
3723 initial thread before NMEM/ODR is used. statserv.c and client.c
3724 have been changed accordingly. The change was necessary to make
3725 NMEM thread safe. The NMEM memory pool is shared amongst threads
3726 in a process. Unix-based applications will still work fine without
3729 Added NT Services interface for the the Z39.50 (statserv) Server.
3730 Refer to the ztest.c source on the usage.
3732 Windows 95/NT port using MSVC5.0. Project files are included in the
3735 * Defined new 'global' handle for the retrieval (data1) system. The
3736 new handled, data1_handle, describes the state of the data1 system.
3737 This handle is passed as first argument to virtually all
3738 data1 related routines. The functions data1_create and data1_destroy
3739 creates and destroys a data1 handle respectively.
3741 Added ODR encode stream member to all backend request structures
3742 init, search, scan etc. This stream should be used to allocate all
3743 memory used for the response when thread safe operation is needed.
3745 Changed the comstack utility, cs_addstr, to be thread safe. The
3746 returned hostname string returned by the function is now part the
3749 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3750 function. The cs_straddr takes a COMSTACK handle as argument, so this
3751 function must be used after cs_create and before bind/connect.
3752 This function is thread safe.
3754 Moved test server to 'ztest' directory - generic server code still
3755 in 'server' directory.
3757 Made prefix query (pquery.c) utility thread safe.
3759 Added new function modifier YAZ_EXPORT to 'export' public DLL
3760 functions when using windows (see include/yconfig.h).
3762 Added definitions to the OID database (util/oid.c) (RVDM).
3764 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3766 Added call to ccl_rpn_delete in client program.
3768 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3769 release of RPN structure.
3771 Added support for C++, headers uses extern "C" for public definitions.
3772 With input from RVDM.
3774 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3775 Thanks to Ronald van der Meer (RVDM).
3777 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3779 Added support for private extensions to the OID database
3780 (oid_setprivateoids()). Thanks to RVDM.
3782 Added optional, physical ANY (key replication)
3784 Fixed null-reference problem in GRS-1 output filter.
3786 Proximity operator added to Prefix Query Format (PQF).
3788 In test client command "base" accepts multiple databases.
3790 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3794 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3796 Smallish bug-fixes in the new encoders/decoders (explain).
3798 Bug fixed in DeleteRequest.
3800 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3802 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3804 Added SOIF syntax (using private OID for now) to retrieval module and client.
3806 Added Update extended service.
3808 Added SearchResult-1 additional info structure.
3810 Added optional CCL (ISO8777) interpreter as separate module. Available
3813 --- 1.2 1996/6/10 (1st anniversary release)
3815 Added Summary record syntax. Lightly tested.
3817 Added OPAC record syntax. Untested.
3819 Added ResourceReport service encoders/decoders. Untested.
3821 Fixed bug in z_Unit - wrong tagging on unitSystem.
3823 Fixed bug in the DiagRecs decoder.
3825 Added options for max PDU size and session timeout to frontend-server.
3827 Added documentation of query-language parsers and other supporting utilities.
3829 [frontend-server] Added Attribute set to the bend_scanrequest API.
3831 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3832 surrogate diagnostics were generated.
3834 [retrieval] Allow multiple local values for attribute.
3836 [retrieval] Allow multiple attributes per element in .abs files. index type.
3838 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3840 --- 1.1pl2 1996/4/10
3842 Minor changes, mostly specific to Zebra's requirements (retrieval)
3846 Repaired bug in frontend server when running multiple listening
3847 endpoints in dynamic mode.
3849 z_External() now won't break if a known, ASN.1 value comes encapsulated
3850 in an octet-string. The value will pass through unmodified in an Odr_oct.
3852 Added a bit of code to the demo client to decode & display
3853 ASN.1-structured records represented in the octet-aligned branch of
3854 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3856 Added z_ext_getentbyref() to the ASN module. Doc updated.
3858 * Completed the SCAN definition in the ASN module. This may break SCAN
3859 code based on older YAZ-versions at compile-time. The fix is easy -
3862 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3863 under the SCAN definition. Remember to initialize this, server-people.
3865 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3866 that this does not extend to ODR and ASN.
3868 Comstack allows insertion of established socket (primarily for
3869 inetd-operation of servers). Doc updated.
3871 Front-end server can now start from the inetd in TCP mode. Doc
3874 --- 1.0pl4 1996/1/24
3878 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3879 the rank and record number.
3881 Adjustments to the frontend server.
3883 Fixed diagnostic BER dumper. It ignored the file argument.
3887 Various changes to retrieval module.
3889 Changed the union discriminators of the protocol files from enums to
3890 ints paired with #defines.
3892 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3895 *Changed operator in the RPN structure to 'roperator', again to avoid a
3898 Fixed problems in Explain decoders/encoders.
3900 --- 1.0pl2 1995/12/6
3902 Memory bug in log module fixed.
3904 --- 1.0pl1 1995/12/5
3906 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3908 Bug in Explain DatabaseInfo module fixed.
3910 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3914 The shift to v1.0 signals that we now consider the *core* functionality
3915 of YAZ reasonably stable (the core being more or less equivalent to
3916 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3917 tested (Explain not at all - though that will happen soonish).
3919 Minor changes to code to support Windows port.
3921 Various minor changes after we're getting to use GRS-1 & co. more.
3923 Added Espec-1 format.
3925 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3926 of the protocol and it cannot be selected when encoding (maps into 'string'
3927 when decoding). Needed to talk to some servers.
3929 Demo client can request simple element set names.
3931 Added Diagnostic Format encoders/decoders.
3933 Added simple Close handling to frontend server (no hooks for resource
3934 reporting yet), and demonstration client.
3936 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3938 --- 1.0b3 1995/08/24
3940 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3941 handled incorrectly when records were requested in the searchResponse. This
3942 will only affect you if you use the frontend-server.
3944 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3945 Test-client will ask for and print GRS1. Ztest will return dummy records
3948 Added Explain encoders/decoders to the service-level API. Untested.
3950 Added Extended Services: Item Order encoders and decoders to the Service-
3951 level API. Untested. We could use a recent copy of the pertinent bits
3952 of the ILL protocol to add those bits.
3954 Added diagnostic format 1 encoders/decoders to the service-level API.
3957 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3958 odr_cons.c, which causes a more correct output.
3960 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3961 was always set to 0 when no records were requested in the searchRequest.
3963 * Added better external-handling. This shouldn't harm old code that
3964 *encodes* externals. It can break code that looks for a
3965 'single-ASN1-type' representation, since those types that are known
3966 are now decoded immediately. Look at the SUTRS sample code in
3967 seshigh.c and client.c. Documentation updated.
3969 Handling of structured records in bend_fetchresponse. Length -1 marks
3970 structured record, type is deduced from format field.
3972 --- 1.0b2 1995/06/27
3973 Fairly quick maintenance release to add SUTRS support.
3975 Fixed handling of SUTRS records in the demonstration client.
3977 * Added format field to the bend_fetchrequest and bend_fetchresponce
3978 structures of the backend API (frontend server). When the record is
3979 returned, the value of the format field is mapped to an OID. The
3980 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3981 of the record. The special value VAL_NONE in the bend_request means
3982 that no specific format was requested by the client. Documentation
3983 updated accordingly. Test server (ztest) will return a fixed dummy
3984 SUTRS record if your client requests SUTRS.
3986 Documentation updated accordingly.
3988 You can now set external libraries and RANLIB support in the top-level
3992 First public release.
