3 Call exsltRegisterAll in yaz_init_globals, so that all applications
4 using YAZ will have EXSLT things enabled.
6 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
8 Update various URLs to the re-organized SRU pages at LoC.
12 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
15 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
16 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
17 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
22 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
26 Fix gcrypt not properly initialized YAZ-740.
30 Describe memcached option for ZOOM.
32 ZOOM: throw present request out of range again YAZ-739
33 Was removed in YAZ 5.0.13.
37 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
38 with localtime_r when threads + fork is used (such as Metaproxy).
40 yaz-config: quote some RHS values (that might include blanks)
42 zoomsh: shows SearchResult-1
44 zoomsh: sortby command
46 zoomsh: use proper list of connections and result sets YAZ-725
48 Avoid yaz_log in sigterm handler for GFS YAZ-737
49 Logging is still performed, but outside sig handler.
51 New ZOOM C feature: result-set caching with memcached. Example:
52 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
54 Remove SSL via OpenSSL support YAZ-732
55 Also deprecate two functions from comstack that aren't working with
56 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
58 Revert "Bison: use %name-prefix directive rather than -p option"
62 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
64 SRU GET/Solr base URLs may hold additional ?args YAZ-729
65 ZOOM option extraArgs already does this, though. It seems useful
66 when dealing with Solr targets to limit by filter, eg.
67 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
69 Remove #fragment for HTTP request encoding YAZ-730
71 Doc: Update list of DLLs/LIBs
73 Doc: update href link to Unix utils and Git.
77 ZOOM: fix "lost connection" problem with servers that uses both squid
78 and another proxy behind it that returns Location headers with relative
81 zoomsh: do not use readline for stdin (no tty) YAZ-724
82 Just use fgets in that case. If the user hits Ctrl-D a new-line
85 zoomsh: empty command ignored YAZ-723
86 rather than performing exit of zoomsh.
88 yaz-url utility offers option -v to enable verbose mode.
90 yaz_url uses yaz_check_location and offers verbose mode.
92 Add new function yaz_check_location.
93 This function gets an absolute URI from Location (HTTP redirect).
95 cookie API: introduce yaz_cookies_reset
97 Update cql.y for newer bison YAZ-720
98 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
99 longer supported. Instead one must use %lex-param and %parse-param .
101 --- 5.0.10 2014/01/09
103 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
106 rpn2solr: support truncation left(2), left&right(3) YAZ-718
108 Mention SRU version 2.0 in yaz-client man page.
112 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
117 Make cs_parse_host public.A
119 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
120 introduced in YAZ 5.0.6.
124 Fix buffer corruption for yaz-ztest record fetch.
128 Allow yaz-ztest to return user-defined records (one record per file).
129 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
131 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
132 Use the stream write instead of odr_printf which has a 4K tmp buffer.
134 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
138 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
139 can read and write this format. For record format JSON, yaz-ztest returns
140 MARC-in-JSON records.
142 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
143 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
147 Improve error reporting for ICU chains YAZ-707
148 Report config element+rule when ICU status is "failure".
150 ZOOM: stop fetching if present response has no records YAZ-710
151 Some targets return less records than their hit count would suggest.
152 This prevents ZOOM from continuing to fetch records if any present
153 response has 0 records in the response.
155 Ensure that GFS calls exit if any listener fails YAZ-710
156 Before, if XML config was in use, it would start the default
161 yaz-ztest: -V shows version (like yaz-client -V)
163 New iconv encoding: danmarc YAZ-692
165 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
167 daemon: only wait for immediate child rather than all children. YAZ-704
169 yaz-client: fix setting of SRU record schema. If scheme was unset, it
170 could lead to invalid memory reference.
174 yaz-ztest returns schema for MARCXML test records. SRU require that
175 recordSchema for records.
177 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
178 instead of non-surrogate diagnostic. This is a per-record failure.
180 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
181 may refer to multiple listeners now. Attribute listenref is a comma separated
184 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
185 option is given for GFS, the dirname of filename (for -f) is used
186 as prefix for options such as cql2rpn, ccl2rpn, etc.
188 Content-Type charset fixes YAZ-701 . Do not inspect charset in
189 Content-Type header for SOAP when decoding SRU. The payload (XML)
190 itself tells what encoding it is. In response, never supply encoding
191 in Content-Type. The response payload (XML) tells what it is (with no
192 encoding in XML it's UTF-8).
194 HTTP decoding: allow blanks in URL paths YAZ-700
198 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
199 and facets. Ensure recordData and recordSchema are always present in
200 record element, because they are required.
202 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
205 Simplify in a lot of places using odr_strdupn.
207 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
211 Increase various buffers in GFS's statserv_options_block
212 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
213 This change makes many type-casts redundant, and, thus simplifies code.
215 Remove last bits of WAIS support.
217 Remove member 'size' from Odr_oct.
219 Slim down the public part of 'struct odr'. Most elements are not part
220 of struct Odr_private.
222 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
223 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
224 In particular facets are supported in both client - and server side.
225 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
226 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
227 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
228 both request/response). This is what a search handler in the GFS
229 will see (regardless of whether operating in SRU mode or Z39.50).
231 Changes to the srw.h (SRU/Solr) definitions include:
232 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
233 (char*), which replace union query and query_type (int). This is because
234 SRU 2.0 supports a queryType parameter. This also means that, to carry
235 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
236 x-pquery=PQFstring (extention parameter). The extension parameter
238 - New element, packing, that has information about SRU
239 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
241 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
243 New element, packing, in Z_SRW_explainRequest.
245 New elements in Z_SRW_scanRequest, queryType and scanClause.
246 These replace query_type and scanClase untion. This is similar to what
249 --- 4.2.69 2013/10/01
251 GFS: log when closing down - at least SIGTERM YAZ-684
252 Also change formatting WRT PID logging a bit.
254 Improve display of MARC records with multi-byte subfield IDs YAZ-695
255 In some rare cases subfield identifiers are multi-byte characters.
256 This will try to deterime length of those and split accordingly.
257 This affects display in line mode as MARCXML/MarcXchange. The encoding
258 of ISO2709 is the same.
260 Change inp argument to const for yaz_read_UTF8_char.
262 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
264 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
266 Better check of marc leader info YAZ-691
267 Problem is that some systems generate MARCXML/MarcXchange with
268 funny headers. These will not work if encoded as ISO2709.
269 Some tests produce new output, due to updated warning messages
271 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
273 yaz-client: display MAB records YAZ-689.
274 Thanks for Heiko Jansen for this patch.
276 New utility z_get_HTTP_Response_server which allows both HTTP server name
277 and HTTP server URL to be given in response.
279 Debian: do not depend on obs tcl8.3.
281 Debian: do not depend on obs libicu36-dev.
283 --- 4.2.68 2013/09/23
285 GFS: pass additionalSearchInfo to search memeber search_input if
286 given. Otherwise pass otherInfo. Request for facets and other search
287 related things will be passed there in future versions of YAZ.
289 New ZOOM setting, authenticationMode, which allows authentication
290 paramters to be encoded in the URL rather than via HTTP Basic auth.
293 rpn2solr: fix nested AND/OR handling. YAZ-685
295 Add comparison routines for some Z-types, such as NamePlusRecord,
296 RPNQuery, Query, RecordComposition and OtherInformation.
298 --- 4.2.67 2013/09/19
300 Don't decode MAB as MARC. Just like we don't attempt to decode
301 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
303 CCL: allow quoted terms for date ranges. YAZ-681
305 Introduce ccl_parser_qual_search. This function makes old function
306 ccl_qual_search, from YAZ 2, available again.
308 Add yaz_facet_list_to_wrbuf. YAZ-683
310 --- 4.2.66 2013/09/11
312 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
313 schema was given for search. YAZ-675
315 Add Solr date range searches. YAZ-621
317 --- 4.2.65 2013/08/22
319 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
321 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
323 ISO2709/MARC parse most octet aligned records; not just those that
324 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
325 MARC parse more records instead of just dumping as is. YAZ-670
327 ZOOM: proper caching for variations of record schema. YAZ-671
329 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
331 --- 4.2.63 2013/07/17
335 --- 4.2.62 2013/07/11
337 New utility z_get_HTTP_Response_details - an extended version of
340 New utility yaz_url_get_error which returns error message of last
341 failed yaz_url_exec call.
343 yaz-url and url functions: allow max HTTP redirects to be controlled.
345 New functions yaz_file_glob2, yaz_xml_include_glob.
346 These functions takes a flags parameter, which, for now only controls
347 whether to fail inclusion of a non-existing file (without glob
348 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
350 --- 4.2.61 2013/06/20
352 For MARC XML parsing, allow record without leader. A fake/default leader
353 is inserted and a warning is tagged with the record.
355 ICU: fix leak in in icu_iter_get_org_info.
357 --- 4.2.60 2013/06/14
359 ICU: fix bug in icu_iter_get_org_info (un-init variable).
361 --- 4.2.59 2013/06/11
363 Implement z_HTTP_header_remove.
365 --- 4.2.58 2013/06/11
367 ICU: Disallow 0 ptrs for some ICU string utilities.
369 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
370 returns original tokens (before normalization).
372 CCL: avoid z39.58/regex truncation when not needed. Apply only the
373 conversion of those masks, when absolutely necessary.
375 CCL: configurable masking character - @mask. Default masking character
378 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
379 full response anyway, so a Transfer-Encoding header will obstruct the
382 --- 4.2.57 2013/05/15
384 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
385 picking a socket. Problem is that some systems has IPV6 support, but
386 we can't create sockets for them, so we pick AF_UNSPEC first.
388 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
389 use content_len to determine resulting Content-Length in HTTP response
390 and NOT Content-Length supplied in headers by user.
392 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
393 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
395 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
398 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
399 with big endian and unsigned char (by default).
401 --- 4.2.56 2013/04/26
403 Fix yaz-client connect (crash in 4.2.55).
405 --- 4.2.55 2013/04/26
407 Fix proxy/host problem for ZOOM that could occur if unix sockets
410 New Debian package libyaz4-dbg.
412 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
413 differently in tcpip_close.
415 --- 4.2.54 2013/04/17
417 Windows installer of YAZ includes YAZ4J as a component.
419 CQL: allow "extra terms" again, by default. Thus, the CQL parser
420 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
421 and earlier. CQL parser may operate in strict mode where queries
422 not conforming to the standard BNF are rejected (syntax error).
423 Whether the CQL parser operates in strict mode is controlled with
424 cql_parser_strict . Strict mode enabled with option -S for utilities
425 cql2pqf and cql2xcql .
427 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
429 --- 4.2.53 2013/04/10
431 New charset, MARC-8c, which is like MARC-8 but allows control characters
432 0x01 through 0x1F, except ESC to be passed through verbatim.
434 Fix a problem with duplicate sub field character in MARC output. Problem
435 happened only when output was MARC-8 encoded.
437 --- 4.2.52 2013/04/03
439 yaz-ztest: Use hash for fake hit count. Before, random number was used.
440 This is problematic for unit tests using yaz-ztest. This patch also makes
441 a hash for CQL queries. For RPN, any term with a leading digit will be
442 treated as pseudu hit count (to force any particular hit count by a client).
444 yaz-ztest: return unique MARC dummy records. Beyond record offset
445 24, the author surname is patched with offset to make all records
448 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
449 on system wide default (/proc/sys/net/ipv6/bindv6only).
450 @4 binds to IPV4 only. @6 binds to IPV6 only.
452 Update CQL API documentation a bit
454 CQL: don't accept extra terms for queries. Makes the CQL parser
455 stricly conformant to the standard.
457 --- 4.2.51 2013/02/12
459 GFS: scan handler gets extra_args from request and may return extra
460 response data . That's for SRU only.
462 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
464 --- 4.2.50 2013/01/30
466 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
468 OPACXML: sync spelling of availabilityDate in XML to that of Schema
469 opaxxml.xsd. The schema had the correct spelling of this member always.
470 The ASN.1 was mis-spelled and still is (API change) - we are
471 not changing this. However, the OPAC to XML conversion had yet
474 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
477 New function, z_ext_record_oid_nmem, which is similar to
478 z_ext_record_oid but takes NMEM rather than ODR
480 --- 4.2.49 2013/01/18
482 ICU: New conversion element 'join' which joins tokens into one
483 with a custom character given by rule attribute.
485 --- 4.2.48 2013/01/10
487 New GFS search member: present_number. This is a hint to the
488 search handler how many records are going to be fetched immediately
489 following search. There's no guarantee that it's going to be the case,
490 since it depends on hit count (for Z39.50 piggyback) and whether errors
493 Make a few functions static (private). The functions getbyte_stream,
494 ungetbyte_stream and yaz_gets are now private. They were never declared
497 yaz-marcdump: exit(5) for serious decoding errors
499 ISO2709 decoding: be more picky WRT header
501 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
502 was only used as to indicate that next-result-set-position should be
504 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
505 Based on patch from Ashley Sanders.
507 Make some functions static/private in PQF parsing. Those functions were
508 never declared in a public header and so should not be in use by
509 applications based on YAZ.
511 --- 4.2.47 2012/11/23
513 ZOOM: special options to control APDU logging.
514 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
515 logging of APDUs until "saveAPDU" option is set again. If logging is
516 already enabled the effect is that current APDU buffer is cleared.
517 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
518 logging (default behavior on new connection).
519 The APDUs sent/received can be obtained by using
520 Using ZOOM_connection_option_get(c, "APDU") or
521 ZOOM_connection_option_getl(c, "APDU", &l).
523 GFS: relay implementation_version from backend
524 From 3.0.40 and later, implementation_version from backend was
525 not used in init response at all.
527 --- 4.2.46 2012/11/15
529 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
530 mode at all. Probably never did.
532 Make a new version of ztest.pem that, at least, is not expired.
534 --- 4.2.45 2012/11/13
536 Fix description of CCL directive 'case'.
538 More tight checking of form arguments (yaz_uri_to_array). Makes
539 YAZ better at rejecting big and/or bad POSTs.
541 SRU decoding does not report more than up to 10 invalid arguments.
543 rpn2cql: less quotes in generated terms. Semantics unchanged, but
544 it's prettier this way.
546 --- 4.2.44 2012/10/25
548 New utility yaz_decode_init_diag. Defined in proto.h.
550 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
551 given for unix local socket.
552 The COMSTACK string for doing so is:
555 unix:/myfile:tcp:localhost:9999/mybase
556 unix:/myfile:localhost:9999/mybase
557 unix:/myfile:http://fakehost/mybase
559 debian: Use dpkg-buildflags in build process.
561 --- 4.2.43 2012/10/19
563 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
564 global's SRU service uses a recordPosition scheme starting from zero.
565 First record's position should be one
566 according to the standard.
568 --- 4.2.42 2012/10/18
570 Allow more namespaces for SRU. This is to allow, for example, an
571 incorrect namespace returned from server
572 http://services.igi-global.com/sru .
574 Minor fixes for compilation on Windows.
576 --- 4.2.41 2012/10/11
578 daemon: log total number of bad signals from child on stop so that it
579 is more easy to spot problems with child worker processes.
581 retrieval: empty backend name attribute omits element set
582 from being used in retrieval.
584 --- 4.2.40 2012/10/04
586 Implement Solr sort strategy "solr", similar to sru11 sorting.
587 This will implement the correct parameters on Solr requst to do
590 --- 4.2.39 2012/09/28
592 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
595 MARC: Extra/missing indicator handled for MARCXML.
596 The indicator length is given in header and is the same for the
597 whole record. If attributes ind1, ind2 are missing, then content
598 character defaults to blank. Extra indicator attributes (beyond)
599 indicator length are treated as an error.
601 Reformat: delete trailing whitespace
603 --- 4.2.38 2012/09/17
605 MARC: fix non-ASCII characters for leader. This is to ensure we can
606 generate XML in UTF-8.
608 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
609 in one node with structure word.
611 --- 4.2.37 2012/09/04
613 yaz-json-parse: JSON output may be pretty printed by using option
616 Increase default value of max message for Z39.50 Init for GFS, ZOOM
617 and yaz-client. Old value was 1 MB. New value is 64 MB.
619 --- 4.2.36 2012/08/22
621 yaz-client: don't display bogus records from SRU servers. Some SRU servers
622 return more records than given by *maximumRecords*. Skipping those in
625 record_render: simplify buffer return handling and fix at least one bad
626 memory reference, that broke the test_embed_record sometimes.
628 Allow http://user:pass@host notation for yaz_url_exec.
630 zoomsh: allow shell command to be executed. Via the system(3) call.
632 yaz_poll: Allow num_fds == 0
634 yaz-client: fix bad encoding of "itemorder item". The itemorder
635 item <no> - command forgot to use length of encoded Item Request
636 package. Error present since YAZ 3.
638 yaz-ztest: fix bad usage of session handle. Bug was introduced when
639 result sets were saved (271a9c83).
641 SRU recordPacking: guess record packing in response rather than looking
642 at the recordPacking element which, OF COURSE, changed semantics in SRU
645 Decode SRU 2.0 responses. The official namespace for responses, according
646 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
647 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
648 nature.com's server, however, usee namespace
649 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
650 we are now using a glob-expr to match up the namespace. ZOOM C and
651 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
652 I can not find a single real example showing the "real" namespace in
653 the documentation from OASIS. The namespace for requests is different
654 from responses, but this is not added to YAZ yet, when we don't encode
657 --- 4.2.35 2012/06/26
659 zoom/record_render: add support for Base64 decoding fo MARC records
660 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
661 which will decode base64 + ISO2709 marc-8 encoded material from text node
664 --- 4.2.34 2012/06/07
666 Add missing definitions ZOOM_resultset_get_facet_field_by_index
667 and ZOOM_resultset_facets_names.
669 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
672 Change APDU dump printing to avoid long leading blanks. For levels 16
673 or larger the level is shown and the indentation is truncated but
674 recursed with modula 8. This makes it still reasonable easy to read
675 - even for nested BER dumps.
677 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
678 return 0 (incomplete package) in case where the BER package was
679 considered too nested (return value of -2).
681 dumpber: lines of level 15 are not indented further. Two spaces per
682 indentation; indentation 15 or more is indented to a fixed indentation
683 and augmented with a level=<no> indication.
685 zoomsh: increase max size of command+args
687 GFS: No limit in RPN buf size in CQL to RPN conversion.
689 --- 4.2.33 2012/05/09
691 New function for daemon utility, yaz_daemon_stop .
693 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
695 --- 4.2.32 2012/04/25
697 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
698 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
700 --- 4.2.31 2012/04/23
702 YAZ daemon utility relays SIGUSR1 to child process.
704 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
705 would result in en empty database list - which in turn would result in
706 encoding failure for search.
708 Fix reading beyond string in yaz_sort_spec.
710 --- 4.2.30 2012/04/11
712 Add two new SRU diagnostics:
713 236: Access to specified database denied
714 1015: Init/AC: Maximum number of simultaneous sessions for Userid
716 Document the very useful ZOOM-C option "apdulog".
718 CQL to RPN: term may be passed through verbatim. This is enabled with
719 truncation.cql . The assumption being that the term is already CQL.
721 --- 4.2.29 2012/03/20
723 record_conv: leader spec may be given for marc element.
724 The leader spec is given as attribute leaderspec for element marc.
725 For example to convert a MARC21 record from MARC-8 to UTF-8:
726 <marc inputformat="marc" outputformat="marc"
727 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
729 record_conv: allow user-XSLT params. For example:
730 <xslt stylesheet="MARC21slim2DC.xsl">
731 <param name="myparameter" value="myvalue"/>
732 <param name="otherparameter" value="othervalue"/>
735 record_conv: fix error handling for missing marc charsets.
737 CQL: fix extra terms in wrong order.
739 --- 4.2.28 2012/03/06
741 record_conv: modify new API for conversion types. The conversion types
742 may be passed in new functions yaz_record_conv_configure_t and
743 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
745 Avoid mixed statement/variable declare; fixes compilation with Visual
748 --- 4.2.27 2012/02/28
750 Add non-standard SRU diagnostic: 235: "Database does not exist".
751 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
752 Update SRU to Bib-1 diagnostic maps accordingly.
754 CCL: add two new diagnostics for unsupported masking. The new
755 diagnostics are: "Embedded truncation not supported" and
756 "Single charcacter mask not supported".
758 --- 4.2.26 2012/02/23
760 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
762 --- 4.2.25 2012/01/11
764 Build YAZ for Ubuntu Oneiric.
766 CCL: allow parantheses for proximity operands. For example CCL query
767 (a) % (b) is now allowed.
769 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
770 marked dead, rather then being destroyed. If not, the session memory is
771 being free'd before the search/scan handler is finished. Also destroy
772 'request' memory in request_release rather than in various places,
773 which resulted in leaks from time to time.
775 --- 4.2.24 2011/12/21
777 cql_sortby_to_sortkeys: honor sort prefix.
779 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
780 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
781 The rpn2cql family of functions now always returns quoted CQL terms.
783 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
785 --- 4.2.23 2011/12/15
787 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
788 sequence is treated as one. For example, &&a=b&&&c& is identical to
791 --- 4.2.22 2011/12/05
793 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
794 APDUs for a connection to a WRBUF.
796 --- 4.2.21 2011/11/23
798 Fix cql_sortby_to_sortkeys. Completely broken before.
800 Make CCL's @truncation work again.
802 --- 4.2.20 2011/11/09
804 New ZOOM connection setting: tproxy. It's like proxy, but does not
805 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
806 to set resolved address + port for a connection outside ZOOM itself.
808 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
810 --- 4.2.19 2011/11/07
812 Fix uninitialized variable in Solr spell support (could cause SEGV
813 for SRU response decoding).
815 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
816 back-end's addinfo through into the ZOOM response addinfo.
818 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
819 they are separated by a colon and a space rather than simply
822 --- 4.2.18 2011/10/28
824 Add support for Solr spell-checking/suggestions through ZOOM.
825 If a Solr target has been configured correctly for spelling-checking
826 and suggestions, these will now be returned on the ResultSet option
827 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
829 --- 4.2.17 2011/09/28
831 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
832 with a flag whether to substitute escape sequences or not.
834 --- 4.2.16 2011/09/22
836 Fix nmem_strsplit_escape to substitute escape char properly.
838 New option for zoomsh -e , which makes it abort on first error and
839 return process exit code to indicate success/failure.
841 YAZ options utility supports special option -- which makes all it treat
842 all following arguments as non-options.
844 --- 4.2.15 2011/09/16
846 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
847 searched if absolute filename is given.
849 Fix conv_xslt() error-reporting when stylesheet is not found.
850 (The value of fullpath is meaningless in this situation.)
852 --- 4.2.14 2011/09/07
854 Fix problem in CQL sort node creation: un-initialized memory.
856 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
857 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
858 CQL sortby depending on whether Type-1 or CQL is actually sent to the
861 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
862 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
864 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
865 will make it possible to use both single-character mask (#) and wildcard (?)
866 in CCL . Throw diagnostic for left truncation because that is not supported
869 --- 4.2.13 2011/09/01
871 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
872 cases using escapes (\-sequences) and masking.
874 PQF parse fix: A trailing backslash followed by end-of-string (\0)
875 would result in a read one byte beyond string.
877 rpn2ccl may use Z39.50 masking for terms (t=z).
879 ICU check fix. Don't include library -lCrun on Solaris, unless present.
881 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
882 not --cppflags (which seeems like an error in icu-config).
884 --- 4.2.12 2011/08/27 RPM package only
886 cql2ccl: fix conversion of terms: operator characters were not
889 --- 4.2.11 2011/08/25 RPM package only
891 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
892 CCL parser will map both # and ? to their regular expression
893 quivalents (. and .*).
895 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
896 of reserved CQL characters.
898 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
899 is, so that they are passed through.
901 --- 4.2.10 2011/08/24
903 ZOOM SRU mode: more aggressive re-connect.
905 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
906 made available as a utility function, declared in <yaz/logrpn.h>
908 rpn2cql_structure() supports proximity nodes (except that the Type-1
909 proximity node's "exclusion" binary is ignored, as there is no way to
910 express that in CQL). Fixes bug #4564.
914 Fix SEGV that could occur if set command of zoomsh was given without
915 value (2nd argument).
917 Fix SEGV that could occur if unsupported transport was given for
918 COMSTACK - say https (when SSL was unavailable).
920 Build yaz-url on Windows too.
924 New utility to get web content. Header is url.h. A command line tool
925 yaz-url is part of the distribution and packages.
927 Fixes for SSL COMSTACK (when gnutls is in use).
929 New functions yaz_base64{encode,decode}. Header is base64.h.
933 ZOOM C includes HTTP response buffer as additional info if it fails
934 to decode the SRU response.
936 Make wrbuf_json_puts available.
940 zoom: throw diagnostic for invalid value for option "sru". Before a
941 bad SRU request was sent.
943 Adding new utility wrbuf_vp_puts.
945 Add cclxmlconfig.obj to win/makefile. It was missing completely.
949 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
950 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
951 redirect was used at the same time.
953 MARC line mode decoding: be less picky about length given - first
954 5 digits of header that is.
956 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
958 Changes to decoding of SRU records: a record with recordPacking=xml is
959 modified with a new root element <yaz_record> if the recordData contains
960 multiple children elements. This is to make the record XML parseable
963 RPN to Solr conversion: encode special characters.
965 Generic Frontend Server: fix uinitialized member, stepSize.
969 Fix a bug in SRU decoding of records.. The database records stored
970 had un-initialized memory, but it would only be seen with yaz_record_render
971 and type_spec="ext" .
973 Fix a bug in ccl_qual_dup introduced in 4.2.3.
977 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
981 Add new utilities to convert from CQL to CCL . These utilities have
982 prefix cql_to_ccl defined in cql.h.
984 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
985 lead to memory heap corruptions when ICU utilities were in use.
989 Make compilation work without Libxml2.
991 yaz-client: remove redundant blanks in display of searchResult-1 term
996 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
997 resulting CQL node (tree) in a new node CQL_NODE_SORT.
999 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1000 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1001 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1002 Note that the CQL sortby spec is only converted when the GFS is already
1003 converting from CQL to RPN (cql2rpn element).
1005 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1006 specify whether to collapse delimitors or not. The existing nmem_strsplit
1007 do collapse (collapse parameter = 1).
1009 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1011 Rename internal func yaz_use_attribute_create. While non-static, this
1012 function is not declared in a public header.
1014 --- 4.1.7 2011/03/15
1016 Add -lCrun when linking with ICU on Solaris.
1018 More quicks character set conversions for OPAC records.
1020 --- 4.1.6 2011/03/10
1022 fix problem with record_render: records were converted (character set
1023 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1025 --- 4.1.5 2011/03/08
1027 SRU: add methods for handling DADS SRU-proxy facets.
1029 Separate OPAC record character set for ZOOM_record. yaz_record_render
1030 allows a character set given as charset=from/opacfrom,to where 'from' is
1031 the character set of a bibliographic record, 'opacfrom' is character set
1032 of OPAC record and 'to' is the target character set.
1034 --- 4.1.4 2011/02/21
1036 yaz-client: show may XML format records. Command show followed by 'format'
1037 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1040 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1043 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1045 --- 4.1.3 2011/01/27
1046 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1048 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1049 this package can be distinguished from other vendors.
1051 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1052 as determined by configure
1054 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1056 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1057 returns no error and no record, the present request is considered
1058 partial (only a subset of the records could be returned by backend), and
1059 so it is appropriate to set Present Status to partial-4.
1061 --- 4.1.2 2010/11/02
1063 Move yaz-config man pages to section 1.
1065 More documentation about Solr.
1067 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1068 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1069 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1070 peers on some Linux systems. However, in general that does not work
1071 so YAZ can not rely on that to work. Debian changed behavior in this
1072 respect from Debian lenny to Debian squeeze (still testing as of Oct
1074 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1076 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1078 --- 4.1.1 2010/10/05
1080 Fix yaz-config output: echo_source not set correctly by configure.
1082 --- 4.1.0 2010/10/05
1084 Solr Web Service support for yaz-client and ZOOM.
1086 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1088 --- 4.0.12 2010/08/17
1090 Z39.50 facet support. Facet specifications are passed for search in
1091 other-information with ASN.1 as defined in facet.asn and OID
1092 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1093 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1094 3 is limit (number of entries to get in response). yaz-ztest returns
1095 dummy facets if a client asks for them.
1097 --- 4.0.11 2010/07/09
1099 CCL fixes: bug 2895 and bug 3539.
1101 GR1-display: add comma in display - was removed by mistake in
1104 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1106 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1108 --- 4.0.10 2010/06/18
1110 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1111 result set from a connection. The result set will be on its own
1112 thereafter; no operations on it will perform retrievals from a target.
1113 Only cached copies are returned.
1115 ZOOM C:fix case for HTTP servers responding with Connection:close.
1116 Ensure that if there is a current task it is resumed (like fetching
1117 more records in a result set) . Bug #3484.
1119 PQF parser: use odr_atoi for Odr_int (not atoi)
1121 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1122 values that contain any non-digits are treated as string attributes
1123 (previously decoding only checked for leading character ([0-9]). PQF
1124 encoding: attribute string values are not surrounded by double-quotes.
1126 --- 4.0.9 2010/05/21
1128 New utility for managing threads - thread_create.h.
1130 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1131 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1132 but YAZ' implementation do.
1134 Fixes for yaz_cond-functions on Windows 7.
1136 DLL export more symbols.
1138 zoomsh: show record do NOT render opac.
1140 Remove *.la files from Debian and RPM packages.
1142 --- 4.0.8 2010/05/11
1144 Debian package libyaz-dev depends on libgnutls-dev again (was
1145 removed in YAZ 4.0.6, but due to Libtool it is still needed
1146 even though yaz-config do not list libgnutls libs).
1148 ZOOM: Use only one WRBUF for returning string results for
1149 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1151 ZOOM: ZOOM_connection do not use a shared pointer to
1152 ZOOM_resultset after ZOOM_resultset is destructed by
1153 user. Reverts to YAZ 4.0.4 behavior.
1155 --- 4.0.7 2010/05/04
1157 record-conv: fix problem with at least one XSL conversion -
1158 due to probably incorrect usage of XML XSL documents.
1160 --- 4.0.6 2010/04/29
1162 Fix yaz-config for static mode and the use of SSL (gnutls).
1164 --- 4.0.5 2010/04/29
1166 Forward decl timeval struct in mutex.h and gettimeofday.h.
1168 yaz-config: fix 'static' mode linking.
1170 --- 4.0.4 2010/04/28
1172 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1173 are wrappers for pthreads or Windows. For Windows these are put in
1174 a separate DLL: yaz_cond4.
1176 libyaz.la (whole source) is compiled with thread. If thread support
1177 is enabled enabled, all source of YAZ is compiled with treading support.
1178 This allows core utilities such as yaz_log to use thread facilities.
1179 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1180 thread utilities. This commit moves mutex utilities (mutex.c) from
1181 libyaz_server.la to libyaz.la.
1183 yaz-json-parse displays leading text until error.
1185 --- 4.0.3 2010/04/09
1187 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1188 patch from Giannis Kosmas.
1190 SRU: no longer URL encode SRU database. The URL for an SRU server is
1191 a URL and such is alreeady encoded - at least when given with leading
1192 http:// or https://. This reverts behavior to YAZ 3.0.50.
1194 Support for new MARC XML notation TurboMARC which like MARCXML is a
1195 complete representation of MARC/ISO2709.. This one, however, is more
1196 compact and allows for faster processing with XSLT. TurboMARC can be
1197 used in the marcdisp.h API, from the yaz-marcdump utility and from
1200 yaz-ztest can be configured - via the database - to perform certain
1201 delays when it performs operations search, present and single record
1202 fetch. This allows testers to make yaz-ztest act as a real or even slow
1203 Z39.50 server. Refer to the yaz-ztest man pages for details.
1205 --- 4.0.2 2010/03/09
1207 wrbuf_destroy allows NULL WRBUF passed to it.
1209 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1211 Add ZOOM_connection_close.
1213 No fixed size buffers for ZOOM shell - bug #3257.
1215 tstodr: make it work on s390 platform.
1217 New icu iterator-functions. The new icu_iter-functions makes it possible
1218 to use ICU chains from many threads.
1220 yaz-client: better syntax check for show command.
1222 --- 4.0.1 2010/01/26
1224 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1227 New simple local-file XML include facility which allows file glob-patterns.
1228 Refer to yaz/xml_include.h.
1230 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1233 ZOOM_record_get supports new parameter "format" which makes it format XML
1236 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1237 JSONText in ECMA-262) is JSONValue, not JSONObject.
1239 --- 4.0.0 2010/01/20
1241 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1242 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1244 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1245 POSIX/Unix builds .so with major version 4.
1247 Remove old LOG_-defines from log.h. They have been obsolete and
1248 undefined by default for the last 5 years.
1250 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1252 GFS: Remove socket (int *fd) from search_rr handler. The socket
1253 descriptor ptr is a facility that allowed a search handler to supply
1254 a socket which would serve as a callback - when search was complete.
1255 This facility has now been in use for years.
1257 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1258 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1259 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1260 returns 'const char *' rather than 'char *. The returned string is
1261 read-only and should not be modified by applications. COMSTACK cs_close is
1262 now a void function - it no longer returns int. No applications check for
1263 the value and the implementations has always returned 0.
1265 ZOOM: use size_t for scan hit counts and str size. Functions
1266 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1267 occ (hit count) and len (string length) are now of type size_t pointer
1268 rather than int pointer. This is to be able to represent large hit counts
1269 and to also just to use the proper type for string length (strlen result).
1271 New JSON parser. Refer to include/yaz/json.h .
1273 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1274 Used to be int in some cases. Many wrbuf_-functions used to return an int
1275 indicating some length.. These return values were never used. And so they
1278 ODR: odr_malloc, odr_total now takes size_t for size.
1280 clone_z_type: fix leak; occurred for encoding failures.
1282 --- 3.0.52 2009/12/03
1284 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1285 bug was introduced in 3.0.51.
1287 --- 3.0.51 2009/12/02
1289 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1291 tcpip comstack: fix leak for getaddrinfo.
1293 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1294 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1295 Decoding of SRU "path" database is performed by private function
1296 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1297 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1299 yaz-client: honor base command for SRU. Change when database setting
1300 is applied for SRU and ensure it is kept when a connection is reset.
1301 Change also the way errors are displayed or SRU (decoding of packages).
1303 --- 3.0.50 2009/11/02
1305 Add support for extra request / response data for SRU codecs and GFS.
1306 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1307 for extra data response buffer and length. For the GFS, both request
1308 and response data (XML) is carried in extra_args and extra_response_data
1309 for the search handler. Patch by Ko van der Sloot.
1311 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1312 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1313 10010). This fixes bug #2113.
1315 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1316 cmdfile included a 'quit' command that would result in a memory violation.
1318 --- 3.0.49 2009/10/01
1320 Make a number of functions defined in xmlquery.c static. These have
1321 never been declared in a public header file (yaz/xmlquery.h) and was
1322 made public by mistake.
1324 Improve speed of character conversions (iconv utilities). This makes
1325 conversions from MARC-8 faster.
1327 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1328 unless type desired is "raw". This will prevent type "xml" from
1329 returning ISO2709 .. Which obviously can not be XML parsed.
1331 Fix memory leak in ZOOM that would occur if option apdulog was used
1332 on a re-used connection.
1334 Frontend server logs HTTP requests.
1336 Frontend server now sends Z39.50 close when it times out (sesssion has
1337 been idle for too long). Versions 2.0.30 and earlier also sent close.
1338 But due to a mistake this was disabled in all versions after that, i.e.
1339 the server would just close the socket immediately.
1341 yaz-client emits a better message when receiving an unrecognised
1342 userInformationField.
1344 Skip zero-length subfields when decoding ISO2709. This rare case happens
1345 if a record has two FS characters in a sequence. Without this patch
1346 there would be a reference beyond char array in using_code_len fragments
1349 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1351 --- 3.0.48 2009/08/28
1353 The show command offered by the zoomsh command now takes a 3d optional
1354 parameter type which is what is passed to ZOOM_record. If the type
1355 argument is omitted, "render" is used.
1357 RPN to CQL conv may use USE string attributes (bug #2978).
1359 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1361 --- 3.0.47 2009/07/08
1363 Function yaz_xml2query allows a diagnostic element in the PQF XML
1364 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1365 code and additional info respectively.
1367 The BER BOOLEAN is now the integral type Odr_bool which still happens
1368 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1369 typedef'd to Odr_int. This is still an integral 'int', but it may be
1370 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1371 ASN-1 compiler as well as programs has been updated to use the new types.
1373 --- 3.0.46 2009/06/08
1375 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1376 only the bibliographic record was rendered. For type=opac, an OPAC
1377 record is only returned if it is present.
1379 iconv: small fix for encoding of advancegreek.
1381 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1383 yaz-client: option auto_reconnect=on really reconnects.
1385 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1387 server: avoid null ptr ref for for yaz_poll errors.
1389 build: fix RPM build for RHEL 5.3.
1391 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1393 --- 3.0.45 2009/03/31
1395 Fixed bug #2709: TCP connect returns Invalid argument.
1397 Fixed compilation for mingw.
1399 Honor charset for raw records (ZOOM_record_get).
1401 Fixed use of errno for threaded mode that was seen on Solaris 10.
1403 Fixed argument passing with blanks in value for Windows Service.
1405 Disable YAZ' own log rotate by default (no 1 GB limit).
1406 The variable l_max_size which specifies the log file limit is set to 0
1407 (DISABLED): This is due to the fact that YAZ is most often deployed using
1408 logrotate. Also YAZ can not perform log rotate because of unsufficient
1409 permissions (setuid).
1411 --- 3.0.44 2009/02/17
1413 List supported encodings in man page for yaz-iconv.
1415 Fixed missing SSL libs for --libs output
1417 Re-established OID record syntax application-xml. Nobody should use it
1418 but we don't want to change soname because of this symbol being absent.
1420 --- 3.0.42 2009/02/02
1422 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1424 Added member named_result_sets for init handler struct for the GFS. This
1425 allows a server to disable named result sets.
1427 Removed OID record syntax application-xml.
1429 Added support for rule-based transliterator for ICU wrapper of YAZ.
1431 Fixed bug #1902: yaz-icu XML output.
1433 Make YAZ checks Emacs friendly.
1435 BITSTRING value shows value. Bug #2346.
1437 ISO2709 decoding: skip control characters from indicator data.
1439 Omit sort key by default in yaz-icu's output.
1441 Allow combined single char options (again) for YAZ' options function.
1443 Utility yaz-marcdump got option to display YAZ version (-V).
1445 Allow YAZ to use ICU 3.4.
1447 Added new ICU test case which illustrates removal of diacritics.
1449 --- 3.0.41 2008/12/29
1451 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1453 --- 3.0.40 2008/12/29
1455 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1458 Fixed bug #2352: yaz-marcdump crashes for certain record.
1460 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1462 Added support for Danmarc2 to UTF-8 conversion.
1464 Added support for ISO5426 to UTF-8 conversion.
1466 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1467 implementation version.
1469 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1471 --- 3.0.38 2008/11/10
1473 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1474 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1476 ZOOM C now interprets databaseName option for ZOOM connection as path
1479 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1481 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1483 Dummy Libxml2 types no longer defined in headers of YAZ'.
1485 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1488 --- 3.0.36 2008/09/26
1490 Various ODR chapter fixes.
1492 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1494 Added missing source for Windows compilation, mutex.c.
1496 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1498 For SRU connections in ZOOM all records up to "count" are now fetched.
1500 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1501 in Windows due to bad error handling for Libxml2.
1503 Added facility for sending arbitrary records (ASN.1 any) using
1504 ZOOM C's Extended service update. Patch by Sam Reynolds.
1506 New options for ZOOM C's connection, logapdu which makes ZOOM log
1509 --- 3.0.34 2008/06/18
1511 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1513 --- 3.0.32 2008/06/12
1515 Fixed memory violation that could occur when decoding UTF-8. This bug
1516 was only present in 3.0.30 of YAZ.
1518 --- 3.0.30 2008/06/06
1520 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1521 GNU TLS is used by default (if found).
1523 yaz-ztest returns OPAC records if a client asks for OPAC.
1525 Improved speed of MARC-8 encoding.
1527 Added support for lossy and loss-less MARC-8 encoding.
1529 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1531 Added new Windows Service wrapper (sc).
1533 yaz-client's itemorder command may now send a file.
1535 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1537 Added new function yaz_log_xml_errors.
1539 Allow (but warn) unknown XML attributes in MARCXML parsing.
1541 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1543 The UTF-8 to MARC-8 conversion now uses a different set of characters
1544 for Greek symbols. Bug #2120.
1546 --- 3.0.26 2008/02/21
1548 Added yaz_daemon (daemon.h).
1550 Fixed bug #2068: pkg-config trouble
1552 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1554 --- 3.0.24 2008/01/28
1556 Document --with-xml2 option.
1558 Added OPAC XML XSD (etc/opacxml.xsd).
1560 Allow glob mask for name attribute in retrieval element for the
1561 generic frontend server's retrieval facility.
1563 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1564 except POLLIN/POLLOUT.
1566 Fixed error handling in cs_listen. Bug #2037.
1568 --- 3.0.22 2008/01/20
1570 Fixed version in yaz/yaz-version.h.
1572 Fixed bug #2027: Crash when closing connection.
1574 Changed configure so that ICU support is only enabled if only ICU
1575 and Libxml2 is available (because the ICU chain is XML based).
1577 --- 3.0.20 2008/01/15
1579 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1580 is built. Only this DLL depends on the ICU runtime.
1582 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1583 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1585 Changed license of CCL module to 'Revised BSD'. After consultation with
1586 remaining members of the original EUROPAGATE consortium, we are re-issuing
1587 the CCL module without a separate license. The software was developed by
1588 Index Data as part of a research project. The special license was included
1589 to help feed usage information back to the project consortium to support
1590 project evaluation. At this time, the project consortium has long-since
1591 disbanded, and the majority of the original principals have retired. At the
1592 same time, we have significantly modified the software during the following
1593 years, to the point where very practically no original code remains. To
1594 simplify re-use of the software, we have contacted those members of the
1595 consortium who could be reached, and agreed to re-issue the module as a
1596 proper part of the YAZ package.
1598 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1600 CQL closer to being version 1.2 compliant. CQL also allows free-form
1601 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1604 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1605 bug could make Extended services handling crash in the ZOOM layer. This
1606 bug was only present in YAZ 3.0.18.
1608 --- 3.0.18 2007/12/19
1610 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1613 yaz-marcdump reads and writes collection wrapped records.
1615 Handle OPAC for record conversion module.
1617 Fixes for ICU wrapper.
1619 Allow ICU libs to be controlled with --with-icu .
1621 --- 3.0.16 2007/11/12
1623 Added yaz_poll which is a wrapper for select/poll. When poll is available
1624 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1625 sockets to be in use.
1627 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1628 functionality through an XML based configuration (ICU chain). This system
1629 is useful for search facilities such as Pazpar2 and Zebra that needs to
1630 perform tokenization of indexed material. The ICU code in a separate
1631 library libyaz3_icu.a.
1633 Added HTTP tunnel facility for COMSTACK, bug #1752.
1634 This is a facility that allows a Web proxy, such as squid, to tunnel
1635 Z39.50 traffic. This facility is "transparent" to must applications
1636 using YAZ. It's enabled by using pseudo transport connect: followed by
1637 the proxy address, followed by command, then follwed by he regular
1638 "virtual" addresss. For example,
1639 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1641 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1643 --- 3.0.14 2007/09/21
1645 Fixed bad memory reference in ZOOM_record - cuased by member not being
1646 initialized. This was a problem only in YAZ 3.0.12.
1648 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1649 fields were not removed.
1651 Changed the way C code is generated from codetables.xml. Made a MARC-8
1652 conversion trie for each characterSet section rather than codeTable.
1653 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1654 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1656 --- 3.0.12 2007/09/12
1658 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1659 from ZOOM_record_error).
1661 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1663 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1665 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1667 Better SRW-to-Bib-1 diagnostic mapping.
1669 ZOOM C and yaz-client announces SRU version 1.2 by default.
1671 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1674 Fixed in yaz_sru_decode to allow other version than 1.1.
1676 --- 3.0.10 2007/08/22
1678 Added support for SRU scan for ZOOM.
1680 Added support for the use of the older versions or Extended Service
1681 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1682 set to the version , 1=first, 2=second, 3=third. The third version is
1683 what ZOOM C has used so far. And that, obviously, is the default.
1685 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1686 therefore in Zebra and in SimpleServer-based applications). The new
1687 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1688 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1689 which is passed into the back-end search callback function.
1691 Added support for HTTP Basic authentication in clients: the SRU/W
1692 codec encodes the username/password elements of the PDU structure
1693 appropriately, and these may be set using the "user" and "password"
1694 options in ZOOM-C applications (the same options that are used for
1695 Z39.50 authentication).
1697 --- 3.0.8 2007/06/25
1699 Fixed bug #1208: SSL appears to be broken in ZOOM.
1701 Fixed bug #1206: Libxml2 include path weirdness.
1703 Added oid_name_to_dotstring.
1705 Allow elementSetName to be specified for ZOOM C record update.
1707 Allow waitAction to be specified for ZOOM C based for Extended Services.
1709 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1710 syntax OID. Bug introduced in YAZ 3 series.
1712 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1714 --- 3.0.6 2007/06/06
1716 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1717 directory. yaz-client now reads commands from file given by option -f
1718 if specified; then tries to read .yazclientrc in current directory.
1719 Failing that, it reads .yazclientrc from user's home directory.
1721 Added support for correlationInfo Note and ID for Record Update via
1724 Added yaz-client command querycharset which specifies character set for
1725 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1726 (termListAndStartPoint).
1728 Charset ISO5428:1984 is an alias for ISO5428-1984.
1730 Implemented a way to perform scan in a result set using Z39.50. This
1731 is achieved by attaching the result set name in the characterInfo
1732 (type InternationalString) of OtherInformation in the Scan Request PDU.
1733 The result set is identified in the otherinformation by the new OID:
1734 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1735 This allows for scan in result set and faceted search . Zebra did some
1736 of this in the APT term using attribute type 8 and value being result
1737 set. Using the OtherInformation approach for this is cleaner and easier
1738 to work with in proxies and the like. This facility can be used in
1739 yaz-client using new command setscan which takes a result set as first
1740 argument, start position (APT) as second.
1742 Changed decoding of SRU XML packed records to deal with servers that
1743 have recordData with XML data with multiple root nodes. Also make
1744 comparison for recordPacking case insensitive. Again, one server
1745 returns "XML" where others return "xml".
1747 For SRU responses allow Content-Type application/xml as well as text/xml.
1749 --- 3.0.4 2007/05/21
1751 Fixed bug in character set conversion of BER strings. Bug introduced
1754 --- 3.0.2 2007/05/08
1756 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1758 For OID class, use oid_class consistently.
1760 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1763 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1764 character set for bibliographic information interchange". By Giannis Kosmas.
1766 Added documentation on new OID API.
1768 --- 3.0.0 2007/05/02
1770 Changes to generic frontend server interface: added new member
1771 'query_charset' for bend_initrequest structure. A backend init handler
1772 should set this member to its native character set for query terms.
1773 When defined, the frontend server logic will announce this character set
1774 to a client if the negotiationModel bit is set by the client. All server
1775 implementors are encouraged to specify this. If a backend server does not
1776 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1778 Added CCL utility to remove terms (stop words) from resulting RPN
1779 tree. This is handled by functions with prefix ccl_stop_words_ .
1781 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1782 terms in RPN queries.
1784 Clean-up the CCL API. Moved some internal structures from ccl.h to
1785 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1786 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1787 This is replaced by ccl_parser_find_str which takes a string instead.
1789 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1790 libyaz.la is the core of YAZ except the generic frontend server and
1791 does not depend on POSIX threads anymore. libyaz_server.la is the
1792 generic frontend server facilities and uses POSIX thread functionality
1793 if available. The libyaz.la no longer depends on POSIX threads because
1794 the number of global structures is limited. NMEM no longer re-uses blocks
1795 between threads ; it simply free's memory immediately but allocates in
1796 "large" chunks as usual. We don't expect any performance penalties
1797 because of this. The yaz_log system is still using a global log_level so
1798 caution must be taken when modifying it with yaz_log_init_.. +
1799 yaz_log_mask_str. This, however, should not cause any trouble because
1800 these functions are called during initialization of application code
1801 anyway. `yaz-config --libs server` returns libs for server applications;
1802 `yaz-config --libs` returns libs for non-server applications.
1804 New OID database - with public definitions in oid_db.h. Removed old OID
1805 database including the head oid.h and definitions such as enum oid_value
1806 and struct oident. The new OID database uses the same string names as
1807 before but the 'protocol' is gone. There are now only two representations
1808 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1809 converts from string to OID; functions with prefix yaz_oid_to_string
1810 converts the other way.
1812 Change to emit_term() in CQL-to-PQF query translation: when a term has
1813 the /regexp relation modifier, do not process it for leading and
1814 trailing "^" and "*", which have quite different meanings in regular
1817 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1818 write handlers no longer carries a 'last' parameter. This will make
1819 yaz_iconv flush "less" characters. A flush is performed by call to
1820 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1822 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1823 removed, because function yaz_query_to_wrbuf does the same.
1825 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1826 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1828 Deprecated MARC utility functions removed.
1830 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1833 Branch split: YAZ_2_1_55_branch
1835 --- 2.1.54 2007/03/16
1837 Fix to ZOOM-C so that transparent reconnection is properly handled on
1838 connections that are in asynchronous mode.
1840 Fixed compilation on OpenBSD 4.0.
1842 Large strings in GRS-1 records are now properly displayed in yaz-client.
1844 Added character conversion support for "advancegreek"; based on patch from
1847 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1848 sequence is met. Before the error was not set so it would be unknown.
1850 Adjust yaz-marcdump MARC reader so that it skips until record separator
1853 --- 2.1.52 2007/03/07
1855 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1856 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1857 fd_set structure used as a bitmask for the FDs to be selected on.
1859 Using ACX_PTHREAD macro to check for POSIX threads.
1861 Fixed have-vsnprintf check.
1863 --- 2.1.50 2007/02/23
1865 Fixes for configure on BSD. Bug #900.
1867 Added snprintf/vsnprintf wrappers for systems that don't have
1868 limits (heavens forbid).
1870 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1871 created before all previous tasks were completed and removed from the
1872 task queue, the new task could be removed by a mistake.
1874 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1876 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1878 Fixed bug #832: Problem with MARC/charset in yaz-client.
1880 Fixed bug #668: save command line history for yaz-client.
1882 Fixed bug #830: pkg-config support.
1884 --- 2.1.48 2007/01/23
1886 Extended ZOOM result set options with two options that may be read by
1887 a client: resultSetStatus and presentStatus with values as specified for
1889 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1891 Fixed bug #827: Using SSL fails on Debian etch.
1893 Fixed bug #826: Weird looking chars for set of MARC records.
1895 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1896 that is treated as an ItemOrder with itemRequest being an XML document
1897 external. The value of "doc" is the content.
1899 Extended the GFS search facility. New member of bend_search_rr
1900 'estimated_hit_count' signals that hits is known to be an estmate
1901 (higher or lower than real hit count). New member 'partial_resultset'
1902 signals that the search was partial (hit count is lower or equal than
1903 real hit count). For Z39.50, the information is stored in resultSetStatus
1904 member of SearchResponse APDU. For SRU, the information is signalled
1905 via SRU diagnostic 59: "Result set created with valid partial results
1908 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1910 --- 2.1.46 2007/01/13
1912 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1914 Added ZOOM_connection_peek_event.
1916 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1917 the following new functions:
1918 ZOOM_event_nonblock, ZOOM_connection_process,
1919 ZOOM_connection_get_{socket,mask,timeout},
1920 ZOOM_connection_fire_event_{timeout,socket}.
1921 The existing blocking event handler, ZOOM_event, is a wrapper for the
1922 + blocking ZOOM_event_sys_{poll,select}.
1924 Implemented function ccl_xml_config which parses XML version of CCL
1925 configuration (bug #798).
1927 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1929 Added timings utility (yaz/timing.h)
1931 --- 2.1.44 2007/01/03
1933 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1936 Fixed bug #779: Rotation of apdu.log fails.
1938 Fixed for character set conversions:
1939 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1940 Honor G1 set in MARC-8 decoding.
1942 --- 2.1.42 2006/12/17
1944 Fixed bug #775: char conversion does not handle Alternative UTF-8
1947 Implemented function yaz_marc_read_line which parses MARC line format
1948 records. There is a wealth of formats out there. So far, this function
1949 reads line records produced by yaz_marc_write_line.
1951 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1952 more generic and easier to remember(!) options: -i format and -o format
1953 which specifies input format and output format respectively - where
1954 format is one of "marc", "marcxml", "line", "marcxchange".
1956 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1957 does not print anything except warnings for records.
1959 For yaz-marcdump, added support for MARC split into files (-s) with a given
1962 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1963 spec, at http://www.loc.gov/standards/sru/record-update/
1964 This has changed the binary layout of the following structs:
1965 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1966 bend_update_rr . Patch by Ko van der Sloot.
1968 Added GFS utility function bend_assoc_is_alive which returns 1 if
1969 association is still alive (client is connected); 0 otherwise (client
1970 closed connection). This allows busy servers to stop working for
1973 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1974 been a separate piece of software. This version of ziffy has been modified
1975 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1977 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1979 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1980 Client code may now interrogate options such as "init_opt_sort" to
1981 find out whether the server claims to support various options.
1983 --- 2.1.40 2006/11/27
1985 Added utilities yaz_{set,get}_esn to set/get element set name from
1988 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1989 of YAZ and has been so since YAZ 2.1.10.
1991 Implemented ZOOM_record_error which returns error information for
1992 record (surrogate diagnostic).
1994 --- 2.1.38 2006/10/31
1996 Updates for SRU Update by Ko van der Sloot:
1997 1. Changed name from "operation" to "action"
1998 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1999 versions in the code, marked as 'backward compatible'.
2000 3. Added diagnostics for SRU Update.
2002 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2004 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2006 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2008 For GFS, fixed problem with SRU diagnostic 'First record position out of
2009 range' being issued for 0 hits.
2011 zoomtst10 part of Windows Build.
2013 --- 2.1.36 2006/10/13
2015 Implemented yaz_filepath_comp which splits a path into file path
2016 components (required by Zebra 2.0.3+).
2018 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2019 BSD inspired license until now so this should not have any real impact on
2020 anybody. See http://www.opensource.org/licenses/bsd-license.php
2022 Fixed bug #687: Missing log lines.
2024 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2027 Fixed bug #689: SRU diagnostics to be added.
2029 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2030 whether a connection is idle (no more work do do).
2032 --- 2.1.34 2006/10/04
2034 Change type of optval from long to int for invocation of setsockopt with
2035 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2037 Added support for specifying the max log file size for the Generic
2038 Frontend Server. The size is given with option -r.
2040 --- 2.1.32 2006/09/21
2042 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2044 --- 2.1.30 2006/09/17
2046 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2049 Fixed bug in Generic Frontend Server that could cause a server to stop
2050 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2052 For the generic frontend server, the maximum record size is used as maximum
2053 size of incoming packages (SRU + Z39.50). The value until was previously
2054 only used in Z39.50 Init negotiation and, later, in a session controlled
2055 sizes of records returned. This is controlled using -k option. It can be
2056 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2058 --- 2.1.28 2006/09/04
2060 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2063 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2065 New option for yaz-marcdump -lpos=value which allows setting a portion
2066 of MARC header to a certain value.
2068 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2070 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2071 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2073 --- 2.1.26 2006/08/15
2075 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2078 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2080 --- 2.1.24 2006/08/08
2082 Fixed MARC ISO2709 encoding routines to deal with character set
2085 Minor changes to GFS logging. Database included in search request log
2088 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2089 cached/multiple records.
2091 Shared libraries are built by default on Unix+configure.
2093 Changed cql2pqf transformation to use a different evaluation order. The
2094 new order is: always, relation, structure, position, truncation, index
2095 and relationModifier. Old order was: always, relation, relationModifier,
2096 structure, index, position, truncation. Note that the the latter ones
2097 override former ones for identical attributes.. The new scheme means that
2098 it is possible to override any existing attribute with a relationModifier.
2099 And also that it is possible to override everything for the index rule
2100 (except the ones listed in relationModifier). No order is perfect but this
2101 one, we believe, covers more real cases.. The "always" should have been
2102 called "default", since the attributes there can be overridden with all
2105 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2106 compilation phase, but also for yaz-config --cflags output. This allows
2107 us to have public headers with Libxml2 stuff in them . It should also,
2108 eventually, make Libxml2 checks redundant in packages using YAZ, such
2111 --- 2.1.22 2006/06/15
2113 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2114 stored in uri, message and details.. Previously diagnostics were stored
2115 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2116 compatibility.. but he's probably the only one affected, so.
2118 Added support for CCL, compiled on the client side, in ZOOM-C. This
2119 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2120 input; the resulting query objects can be used for for searching with
2121 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2123 YAZ' configure searches for OpenSSL by default.
2125 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2126 SL_CTX_use_certificate_file. See
2127 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2128 for more info. Thanks to Ko van der Sloot.
2130 --- 2.1.20 2006/06/02
2132 Bug #600: SRU GET, POST support for yaz-client. Introduced
2133 command 'sru' which selects method SOAP/GET/POST.
2135 Allow missingValueAction to be specified for the sortspec string -
2136 function yaz_sort_spec. By default, the missing value action is null.
2137 Use ! to specify "abort". Use = followed by stringvalue to specify default
2140 Ensured that Present-handler (if defined) is called in GFS before any call to
2141 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2142 searchRetrieve requests.
2144 Documentation for YAZ is now based on the Docbook XML/XSLT using
2145 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2146 is no longer depending on jade/openjade or docbook-to-man scripts.
2147 PDF is no longer part of the distribution - but can optionally be
2148 made using DSSSL/jadetex or FOP.
2150 Added retrieval handling support in Generic Frontend Server to support
2151 conversion between MARC/XML as well as XSLTtransforms. See
2152 etc/yazgfs.xml for an example.
2154 Added Authentication support to Generic Frontend Server in SRU
2155 mode. Authentication using HTTP Basic is supported, as is the use
2156 of 'x-username' and 'x-password' parameters in the request itself.
2158 Added support for a new character set MARC8s identical to MARC8 except
2159 that it converts combined characters to single Unicode characters in the
2160 Latin-1 range (when possible).
2162 --- 2.1.18 2006/04/24
2164 ASN.1 compiler 0.4: generates brief Doxygen file header for
2165 generated .h/.c files.
2167 Utility yaz_iconv now supports conversion to MARC-8.
2169 New facilities for the MARC module. The reading - and writing of
2170 content are separate methods for the yaz_marc_t handle. The following
2171 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2172 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2173 format). Write functions have prefix yaz_marc_write_.. The existing
2174 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2175 available. Removed support for OAI-MARC and simplexml (not the
2176 simplexml from PHP5).
2178 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2179 to be returned for this connection.
2181 --- 2.1.16 2006/03/31
2183 Allow multiple languages and charsets to be specified with
2184 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2185 negcharset iso-8859-1,utf-8
2187 Translation of proximity nodes from CQL into PQF now works.
2189 Moved to automake 1.8, 1.9.
2191 Added function yaz_log_set_handler which allows a log handler to be
2192 installed. This handler will be called for all log messages. Output
2193 to file is also produced; but that can be disabled by passing NULL
2194 fname to yaz_log_init_file.
2196 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2198 For SRW (including GFS), accept application/soap+xml as content-type
2201 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2202 produces NO stylesheet reference even if a default stylesheet is specified
2205 --- 2.1.14 2006/03/14
2207 Updated Windows package to include yazd.dll + yazd.lib for the
2208 Development component.
2210 If the environment variable YAZ_LOG is set, then it is used as a
2211 string indicating the default level of logging to use if not
2212 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2213 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2214 used as before. So, for example, to omit warnings from YAZ logging,
2215 export YAZ_LOG=-warn
2217 cql_transform() now map structure and other attributes before indexes,
2218 so that index-specific structures and other attributes can override
2219 defaults. So now a combination of mapping specifications such as:
2221 index.dc.date = 1=date-modified 4=5
2222 does the right thing.
2224 cql_transform() now also respects the "always" mapping specification,
2225 which establishes an initial set of attributes to be used for all
2226 terms except where overridden by more specific attributes associated
2227 with the index, relation or modifier.
2229 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2230 which mode to use; one of "post", "get" or "soap" (SRW, default).
2232 Fixes for yaz_iconv routines: changed trie-based character set conversions
2233 to use only non-negative values for bit fields due to Sun's C compiler not
2234 supporting negative values.
2236 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2237 sequences where not read correctly. Fix by Rustam Usmanov.
2239 Updated win/makefile to use options, settings which makes things
2240 compile with VS C 2005.
2242 --- 2.1.12 2006/02/01
2244 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2246 In ZOOM socket code, use select instead of poll on MacOSX.
2248 ZOOM-C now support client-side compilation of CQL into RPN that is
2249 sent to the server, enabling CQL to be used against all Z39.50
2250 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2251 ZOOM_query object, and submit it using ZOOM_connection_search().
2252 The CQL-to-RPN translation uses a configuration file, the name of
2253 which must be specified in the Connection's "cqlfile" option.
2255 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2256 function, which takes as its start-term parameter a ZOOM_query object
2257 (which may have had either CQL or RPN set into it).
2260 --- 2.1.10 2005/11/29
2262 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2263 GFS to support this as well. Backend handler, bend_srw_update, does the
2264 update work. Code contributed by Ko van der Sloot.
2266 Allow retrieval of Search Result-1 information in ZOOM by the use of
2267 options that are attached to a result set. ZOOM documentation updated
2270 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2271 UTF-8 conversion. Patch by Raj Patel.
2273 Added option -m to GFS to control formatting of timestamps in log file.
2275 Added 'exit' as synonym for 'quit' in yaz-client
2277 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2278 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2279 for the new members. Patch by Ko van der Sloot.
2281 Added support for SRU POST. It is supported for content-type
2282 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2284 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2285 Instead make the library libyaz.la multi-threaded. Threading as a whole
2286 can still be disabled by configure option --disable-threads. Previosly,
2287 with older GLIBCs there were problems with MT libs under Apache. This
2288 has now been fixed a long time ago.
2290 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2293 CQL module modified to be case insensitive for relations/indexes/operations.
2295 Fixed bug in CQL transform code: incorrect value relationModifieder
2298 Added 'show all' command for yaz-client which retrieves all results
2301 Added new yaz-client, xmles, which takes a (private) OID and
2302 a document to be sent as an extended service request.
2304 Describe new yaz-client commands wait_response and set_auto_wait.
2306 Increase TCP/IP listener backlog from 3 (which I am guessing was
2307 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2308 that the socket will queue as many incoming connections as it's able
2309 to handle ongoing connections. In other words, it will never now
2310 refuse a connection that it would be able to handle merely because
2311 it's not got around to accepting() enough of the pending connections
2312 yet. This is the behaviour anyway under Linux, where the listen()
2313 argument is ignored; but not under BSD and on systems such as
2314 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2315 YAZ-based servers should now be uniform across operating systems in
2318 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2319 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2320 This allows yaz-marcdump to read large MARC batches (>2 GB).
2322 Modified all YAZ source files - except the source which is auto-generated
2323 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2326 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2327 corresponding to the existing *_setl() function. These allow option
2328 values containing arbitrary valuues.
2330 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2331 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2332 except that it returns an indicator of whether or not the sort
2333 criterion was accepted (0 for OK, -1 for invalid).
2335 --- 2.1.8 2005/06/07
2337 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2338 MARC output rather than returning "new" buffer.
2340 yaz-client warns about unknown init options.
2342 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2344 --- 2.1.6 2005/05/24
2346 Added support for SRW sort in Generic Frontend Server. Patch
2347 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2348 sortKeys - or NULL if none is provided.
2350 Fixed bug #307: It was impossible to specify indefinite/no timeout
2351 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2354 Added support for multiple languages and charsets to be specified in
2355 ZOOM. Each charset/language is separated by a blank. If negotiation is
2356 in effect in init-response, Option
2357 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2358 Code based on patch by Vasiliy Osadchuk.
2360 Fixed bug #306: infinite recursion that occurred when calling
2361 yaz_log_level_init as the first call (before other log level or
2364 Fixed bug in scan handling in front end server: if preferred-Position-In-
2365 Response was non-present, a NULL pointer referece was performed.
2367 --- 2.1.4 2005/04/26
2369 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2370 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2371 now defined for all those error codes. So instead of putting 109 in
2372 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2373 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2375 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2378 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2380 Program yaz-client now exits and produces an error message if multiple
2381 Z39.50 servers are specified on the command line (none or one allowed
2384 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2387 --- 2.1.2 2005/03/16
2389 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2391 Fixed bug #272: Preserve spacing for CCL terms.
2393 --- 2.1.0 2005/03/14
2395 Added support for virtual hosts and multiple backend servers for
2396 the YAZ frontend server. The configution is XML based and
2397 support specificition of CQL to RPN mappings and explain information.
2398 See section "Virtual Hosts" in the YAZ manual.
2400 Extended OPAC display utility. OPAC display utility renders
2401 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2402 to supplement yaz_marc_decode_wrbuf.
2404 Fixed a bug in MARC decoder that could caused it to crash for some
2405 invalid MARC records. More diagnostics and warnings where added in
2406 XML output (warnings, etc are stored in comments).
2408 --- 2.0.34 2005/02/08
2410 Fixes for UNIX domain sockets. Bug #261.
2412 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2414 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2415 Added yaz_marc_subfield_str which defines subfield lead string which is
2416 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2417 yaz_marc_endline_str which defines end of fields string used in
2418 YAZ_MARC_LINE format. Default string is newline.
2420 Experimental support for MarcXChange. This format can be produced
2421 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2422 http://www.bs.dk/standards/MarcXchange.xsd
2424 Added yaz-client commands scansize that sets maximum number of
2425 entries to be returned by scan.
2427 --- 2.0.32 2005/01/11
2429 Added support for SRW scan in yaz-client and Generic Frontend Server.
2431 * Added whereInList member to SRW Scan Term.
2433 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2435 Fixed NMEM system to return aligned blocks on the smallest boundaries
2436 that are suitably aligned for all possible types on the particular
2437 architecture YAZ is being built for.
2439 --- 2.0.30 2005/01/04
2441 Fixed numerious warnings that was issued with newer versions of GCC.
2443 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2444 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2447 Make YAZ Generic Frontend Server slightly faster.
2449 Enhance (and reduce) logging for Generic Frontend Server.
2451 Revert YAZ log system so that it flushes every write operation
2452 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2454 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2455 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2456 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2457 will effectively disable old definitions.
2459 --- 2.0.28 2004/11/09
2461 Added yaz_log_time_format which specifies log format using
2464 Added yaz_log_module_level which returns mask for a module. Value
2465 is non-zero mask a if module is enabled; zero if disabled.
2467 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2468 in include/yaz/cql.h.
2470 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2472 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2474 Fixed bug #172: RPM builds does not enable SSL.
2476 Doxyfile.in part of dist. Doxyfile generated by configure.
2478 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2479 are given and the corresponding component does not exist.
2481 Extend CCL documentation in YAZ reference. Describe r=r.
2483 --- 2.0.26 2004/10/01
2485 Fixed MARC->MARCXML conversion to properly deal with
2486 fields, subfields, indicators having non-ASCII characters.
2488 Fixed MARC->MARCXML conversion so that ASCII control characters
2489 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2492 Added YAZ GFS support for conversion from Z39.50 surrogate
2493 diagnostics to SRW surrogate diagnostics.
2495 Bug fix: YAZ GFS did not return schema in explainResponse.
2497 --- 2.0.25 2004/09/30
2499 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2500 now converts recordSchema to elementSetName as well as schema URI.
2502 Fixed bug in COMSTACK that prevented HTTP request packages from being
2505 --- 2.0.24 2004/09/29
2507 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2508 does not require white-space before and after the dash in a range, e.g.
2509 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2512 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2513 due to new GCC removing "redundant" code.
2515 Added yaz-client commands scanpos and scanstep that sets preferred
2516 position and step-size for scan.
2518 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2520 Added CCL utility ccl_qual_buf which parses one or more CCL
2521 spec lines in a buffer.
2523 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2524 of name and value - ignoring empty lines and comments.
2526 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2528 Added odr_get_element_path which returns current element path for an
2529 ODR handle. This utility is useful in error handling or user-defined
2532 Added ODR_PRINT utility odr_set_stream which is is a more generic
2533 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2534 to a write function and pointer to close function. The close function - if
2535 non-NULL - will be called during odr_destroy.
2537 Fixed bug in CCL parser where truncation char was not removed from
2538 right side when truncation=both was in effect.
2540 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2543 --- 2.0.23 2004/08/11
2545 Fix buffer overrun in CQL parser when dealing with proximity (%).
2547 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2548 to UTF-8/UCS conversion is now only based on codetables.xml.
2550 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2552 --- 2.0.22 2004/08/06
2554 Add support for more "commit changes" in ZOOM (uses Extended Services).
2556 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2559 Yet another small fix for configure of SSL.
2561 --- 2.0.21 2004/05/14
2563 Fix SSL libs for configure when --with-openssl=DIR is given.
2565 --- 2.0.20 2004/05/10
2567 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2569 SSL comstack now uses yaz.pem certificate file on server side
2570 by default. Certificate filename can be configured by calling
2571 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2573 Fix bug regarding multiple calls to ZOOM_connection_connect.
2575 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2577 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2578 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2580 ZOOM now allows inspection of X509 peer certificate for verification.
2581 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2583 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2584 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2585 as "modular" but it simplifies things.
2587 Added cs_get_peer_certificate to that returns peer X509 PEM.
2589 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2590 NULL if SSL is unavailable.
2592 Documentation about MARC decoding tools.
2594 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2596 --- 2.0.19 2004/03/30
2598 Rename CHANGELOG to NEWS to follow GNU style packing.
2600 Fix bug with missing initialization of member in init_diagnostics.
2601 This bug affects threaded version of GFS server.
2603 --- 2.0.18 2004/03/20
2605 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2608 Ensure zlib.dll is packed with Windows install.
2610 --- 2.0.17 2004/03/17
2612 Fix encoding of xsd:string to use text instead of CDATA.
2614 Fix endless loop in CQL parser with unbalanced ".
2616 Use a more compact way to store MARC-8 conversion tables.
2618 --- 2.0.16 2004/03/16 Debian only
2620 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2623 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2628 --- 2.0.15 2004/03/01
2630 Another fix for decoding of XML packed records.
2632 --- 2.0.14 2004/02/25
2634 Fixes for Chunked encoding. White space not ignored after length spec.
2636 Update NS and use default NS for SRW diagnostic elements.
2638 --- 2.0.13 2004/02/23
2640 Implement ZOOM_resultset_cache_reset which resets record cache.
2642 Implement ZOOM_resultset_sort which sorts a result set.
2644 Implement chunked HTTP transfer.
2646 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2648 --- 2.0.12 2004/02/16
2650 Added member 'schema' to bend_explain_rr structure so that backend
2651 can specify explain record identifier. Defaults to Zeerex 2.0.
2653 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2655 --- 2.0.11 2004/02/16
2657 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2660 Added init command for yaz-client which sends "extra" init request.
2662 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2663 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2665 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2667 Make ZOOM error code for "invalid query".
2669 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2671 --- 2.0.10 2004/02/05
2673 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2676 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2678 Added option -p <file> to make Generic Frontend Server to write PID file.
2680 Added option -D to put Generic Frontend Server in background on its own.
2682 Make ZOOM C recognize option "password". If unset, "pass" is used
2683 (for backwards compatibility).
2685 Fixed a bug in Generic Frontend Server that could make it crash if a
2686 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2689 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2690 Must be issued before open, in order to be in effect.
2692 --- 2.0.9-6 2004/01/12 Debian/Windows
2694 Make the SRU server more picky WRT unknown params, etc.
2696 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2698 New YAZ client command, options, that sets Z39.50 options.
2700 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2701 options from a string of tokens (one token for each option bit).
2703 Update SRW diagnostic code messages.
2705 --- 2.0.9-5 2004/01/07 Debian/Windows
2707 Handle user defined stylesheet for SRW/SRU.
2709 --- 2.0.9-4 2004/01/06 Debian/Windows
2711 Fix bug in decoding of Content-Length.
2713 --- 2.0.9-3 2004/01/06 Debian/Windows
2715 Fix a bug with decoding of XML packed records.
2717 --- 2.0.9-2 2004/01/05 Debian only
2719 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2721 Fix bug in SRW/SRU diagnostics decoding.
2723 --- 2.0.9 2004/01/05
2725 Fixed bug in Generic Frontend Server which could drop records exceeding
2726 preferred message size. Reported and fixed by Irina Dijour.
2728 Fixed calculation of package size for structured records in Generic
2729 Frontend Server. Reported and fixed by Irina Dijour.
2731 Fixed namespace for SRW/SRU diagnostics.
2733 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2735 --- 2.0.8 2003/12/22
2737 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2738 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2741 CQL changes to reflect recent changes to the specification:
2742 * Documentation talks about context sets instead of index sets.
2743 * Documentation talks about indexes instead of qualifiers.
2744 * The CQL-to-PQF transformer's configuration file now uses
2745 "index.set.name = <attributes>" instead of the old form
2746 "qualifier.set.name = <attributes>". (Both forms are still
2747 understood but the latter is deprecated.)
2748 * CQL terms with no explicit index specified are now interpreted as
2749 cql.serverChoice instead of srw.serverChoice (which of course
2750 behaves exactly the same.)
2752 --- 2.0.7 2003/12/16
2754 MARC conversion can now generate ISO2709 output in another
2755 character set. yaz-marcdump uses this facility if you invoke it
2758 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2759 functions from there can be used from C++.
2761 --- 2.0.6 2003/12/04
2763 Frontend server now transfers memory from decoded packages to stream
2766 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2767 references to show up.
2769 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2770 the ZOOM Abstract API. The older names for the same options are still
2771 also supported for the benefit of old applications.
2773 ZOOM-C supports "implementationId" and "implementationVersion" options
2774 to go along with "implementationName". These allow the user code to
2775 specify identification strings to be sent to servers.
2776 Add OID for the new ExtLite attribute set.
2778 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2779 as requested/supplid by Ere Maijala <ere@atp.fi>
2781 For generic frontend server, reverse the order of
2782 "toolkit-supplied / application-supplied" strings sent as implementationId,
2783 Name and Version. Also, remove the spaces around the slash. This brings
2784 the GFS in line with the behaviour of ZOOM-C on the client side.
2786 Add function ZOOM_scanset_display_term.
2788 yaz-client shows scan displayTerm if present.
2790 Utility yaz-iconv is now installed by default along with the man page
2793 Extend configure check for OpenSSL to use pkg-config where available (such
2796 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2797 server to specify uid/gid/mask for socket using the format
2798 unix:[user=uid,][group=gid,][umask=mask,]file=path
2799 If file= is omitted the existing format is assumed, e.g.
2801 in which case the mask is 0666 (rw for everybody).
2803 Major restructure of YAZ source. All source in libyaz is in src directory.
2804 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2805 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2807 Added man page for utility yaz-marcdump (used to be called marcdump).
2808 yaz-marcdump is installed by 'make install'.
2810 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2811 of incoming package failed.
2813 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2815 Change prototype of odr_perror: add const to message string.
2817 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2819 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2820 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2821 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2822 DNS lookup. There should not be any compatibility problems with this
2823 assuming that blocking=1 or 0 is used.
2825 Fix bad reference in UNIX comstack in function cs_addrstr.
2827 Fix for compilation on AIX.
2829 The generic front-end server (server/seshigh.c) now supports returning
2830 Init diagnostics to the client in User-information-field, in
2831 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2834 --- 2.0.4 2003/09/04
2836 Allow any CQL relation (not just all,any,exact,scr).
2838 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2839 that features the same UI.
2841 Implemented command update0 in YAZ client which is equivalent to
2842 update but uses old of Ext Update ASN.1.
2844 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2845 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2846 Previously no OID was used for this info.
2848 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2849 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2850 returns 'malformed search term' otherwise.
2852 SortResponse member resultCount now set to NULL in sort handler of
2855 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2858 Add three new utility functions for translating OIDs between various
2859 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2860 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2861 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2862 char *oid_to_dotstring(const int *oid, char *oidbuf);
2863 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2865 Reverted modifications for ES Update definition for z_IU0Update
2866 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2867 is back to YAZ 2.0.2.
2869 String value attributes for CCL parser.
2871 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2872 which their FirstSearch server returns in Init responses, sometimes
2873 carrying useful diagnostic information when Init fails. This has the
2874 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2875 "z39.50/oclcui.asn", where its definition is somewhat different from
2876 what OCLC document on their web-site, as required to interoperate with
2879 Support for anonymous authentication in yaz-client. Use the command
2882 * Fix the OID of the Index Data-local "admin" Extended Service from
2883 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2884 the 1000, which indicates a locally-defined OID, was a mistake.
2886 --- 2.0.3 2003/06/20
2888 Fix CCL directive @case handling so that it affects string match for
2889 both CCL keywords and qualifiers.
2891 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2892 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2893 Decoder has been updated with ASN.1 changes as listed in
2894 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2895 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2896 z_IUUpdate, remains unchanged.
2898 ZOOM_record_get may now return a record in a specific character set.
2899 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2900 "from" is the character set of record as returned by target. "to" is
2901 the character set to be returned. If omitted, "to" is UTF-8.
2903 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2905 New ODR utility, odr_getelement, which returns name of element for
2906 which encoding/decoding failed.
2908 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2909 in cases where a required element was omitted.
2911 Bug fix: some MARC8 sequences were not converted.
2913 New ZOOM option "step" which specifies number of records to be
2914 retrieved in one chunk. Used in conjunction with "start" and "count".
2916 SRW support for yaz-client. Use scheme http: to use it, e.g.
2919 yaz-client no longer does (un)intelligent character set conversions
2920 by default. Can be enabled with charset and marc_charset commands.
2922 xmalloc trace fix for 64-bit systems such as DEC alpha.
2924 Solaris 2.6 compile fix.
2926 New function, cql_strerror() translates SRW error codes, as returned
2927 by cql_transform_error(), into human-readable English strings. Used
2928 in yaz-client diagnostics when appropriate.
2930 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2931 converts it into a type-1 query which is sent to the server. This
2932 makes CQL available for use with all Z-servers, as opposed to the tiny
2933 minority that can handle CQL queries themselves.
2935 --- 2.0.2 2003/04/28
2937 New Debian package layout similar to the Redhat Package layout.
2939 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2940 and search result respectively.
2942 --- 2.0.1 2003/04/25
2944 Redhat package is now several packages: libyaz (runtime libraries),
2945 libyaz-devel (development and documentation, and yaz (utility programs).
2946 Package spec file by Morten Bogeskov.
2948 New member 'schema' in struct bend_fetch_rr which the name of requested
2949 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2950 handler MAY set this to reflect the schema of the returned record.
2952 New member 'display_term' in struct scan_entry. GFS now sets member entries
2953 and allocates scan entries to be filled by user scan handler. In previous
2954 version, entries member was allocated by the scan handler. That still works,
2955 but the GFS will ignore member display_term - assuming it was NOT set by
2956 the handler. The fact that the GFS now allocates the entries both allows
2957 for new members and makes a scan handler easier to write.
2959 Fix CQL lex buffer overflow.
2961 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2962 SRU default recordPacking is string.
2964 SRU protocol support for frontend server.
2966 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2968 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2970 Added scan for the ZOOM shell (zoomsh).
2974 * String Identifers for Schemas (Amendment 5).
2975 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2976 Old definition for schema
2977 Odr_oid *schema; /* OPT */
2982 Z_InternationalString *uri;
2983 #define Z_Schema_oid 1
2984 #define Z_Schema_uri 2
2987 * resultCount parameter to Sort Response (Amendment 1).
2988 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2990 Support for SRW 1.0 over HTTP. This is an optional feature and
2991 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2994 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2995 on the same port. SRW SearchRetrieveRequests are mapped
2996 to bend_init,bend_search,bend_fetch,bend_close.
2998 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3000 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3001 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3003 ZOOM connections are SRW based if schem http is used for hostname
3004 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3005 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3007 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3008 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3009 distance=n, order=true/false, relation=le, prox unit=word. If
3010 n is omitted, distance 1 is used.
3012 Fixed problem with C compiler include path in wrong order.
3014 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3015 on Solaris. Patch from Ko van der Sloot.
3017 New MARC decode API. All new functions operate on a yaz_marc_t
3018 handle. The most important new functions are: yaz_marc_create,
3019 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3020 decode and destroy respectively. Decoder can produce formats
3021 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3022 include/yaz/marcdisp.h.
3024 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3025 to UTF-8, UCS-32, wchar_t or Latin-1.
3027 * Prototypes for yaz_iconv_-functions moved to separate header
3028 include/yaz/yaz-iconv.h.
3030 Make a few private functions 'static' in unix.c. This prevents
3031 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3033 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3034 are set when Init Response is received.
3036 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3037 but returns diagnostic set as well.
3039 New function yaz_strerror which is a portable wrapper for
3040 strerror/strerror_r/GetLastMessage.
3042 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3043 is returned for MARC. If type is "oai", then OAI MARC is returned.
3045 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3048 --- 1.9.2 2002/11/26
3050 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3052 Fix bad race conditions on SIGTERM and terminate gracefully in
3055 Move retrieval (data1) module to Zebra since nobody seems to be
3058 Add GRS-1 render for ZOOM using same format as yaz-client.
3060 --- 1.9.1 2002/10/05
3062 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3064 Fix broken ESpec handling in data1 module.
3066 SGML reader parses comments and makes them part of the data1 tree.
3068 Added several type casts so that YAZ compiles as C++ code.
3070 ZOOM didn't handle PDU encoding failures properly.
3072 Added more Bib-1 diagnostics (approved extensions).
3074 GNU configure: better check for iconv.
3076 More portable use of accept, getpeername. Check for socklen_t. Use
3077 int/size_t if socklen_t is not defined.
3081 PQF parser rejects bad queries - including those with extra
3082 characters in them. PQF parser used to silently ignore that.
3083 Cleaner API for PQF added, which allows you to get detailed
3084 error information for bad queries (see yaz/pquery.h).
3086 Fixed bug in ZOOM_record_get for type "database".
3088 Implemented mini iconv library supporting conversions between
3089 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3091 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3093 --- 1.8.9 2002/08/20
3095 Fixed ZOOM C record cache so that preferredRecordSyntax and
3096 elementSetName is used to check for already fetched records.
3098 --- 1.8.8 2002/08/02
3100 Added three members in bend_initrequest structure to facilitate
3101 character set negotiation.
3103 Fixed a bug in frontend server that could cause indefinite
3104 loops under rare conditions.
3106 Revised character set utilities (charneg.h) so that encoding
3107 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3109 For PQF, directive @term <type> sets term type for Scan/Search.
3110 Here <type> is general, string, numeric, null. The term type
3111 is inherited - just like @attr.
3113 New call odr_set_charset that sets character set conversion for
3114 international-strings on a ODR stream. Prototype is:
3115 int odr_set_charset(ODR o, const char *to, const char *from);
3116 The InternationalString is still represented as C string in YAZ
3117 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3118 won't). On the protocol level, you can use any encoding.
3120 Support for UNIX sockets in ZOOM.
3122 Solaris recv sometimes returns errno == ENOENT. It is treated as
3123 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3125 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3126 both client and server. Code by Morten Bogeskov.
3128 --- 1.8.7 2002/05/22
3130 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3131 that they can be used directly from Visual Basic. You must recompile
3132 your windows APP if you're using ZOOM.
3134 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3135 Commands "lang" and "charset" sets language and character set respectively.
3136 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3137 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3139 Attributes from multiple CCL fields may be OR'ed rather than merged
3140 using directive "@field or". Fields are still merged by default -
3141 equivalent to "@field merge".
3143 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3146 Fixed bug in zget for parameter ExtendedServicesResponse.
3150 --- 1.8.6 2002/03/25
3152 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3154 Client displays USR.1:SearchResult-1 (hits per term).
3156 Additional Search Info for search in Generic Frontend Server.
3158 Fixed CCL parsing of "field=s".
3160 WIN32 installer - using the excellent NSIS software from nullsoft.
3162 Fixed CCL parsing of "field = - <number>".
3164 Added function yaz_marc_decode that decodes MARC for line mode
3165 display or XML (similar to that used by JZKit).
3167 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3168 Z39.50. But ISO/ILL was, however.
3170 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3171 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3173 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3174 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3176 --- 1.8.5 2002/02/03
3178 New YAZ client features: Command completion and new commands:
3179 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3180 Code provided by Jacob Poulsen.
3182 New call oid_trav, that visits all registered OIDs via callback.
3184 Function ZOOM_record_get now returns const char pointer rather than
3185 void pointer. It saves a lot of type casts.
3187 For YAZ client, command "auth" now allows you to set authentication
3188 in IdPass style. It is enabled when three tokens are given - order
3189 is user, group and password.
3191 Fix memory leaks in MARC record handling for ZOOM.
3193 New option for YAZ client, -k <kilobytes> that sets
3194 maximum record size. Similar to -k option for generic frontend
3195 server and yaz-ztest.
3197 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3199 Prefix query parser reports "fail" when bad attribute set is given.
3201 Fix in MARC decoder. Proximity logging. Fix for attribute set
3202 in scan handler for server. Patches by Shigeru Ishida.
3204 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3207 Configure option --with-openssl=<dir> now works when a directory is
3208 specified. Patch provided by Morten Bogeskov.
3210 New option for YAZ client, -u <auth>, that sets authentication.
3212 ZOOM fix: error information was sometimes "missing", since error
3213 was cleared/reset too when it shouldn't.
3215 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3217 --- 1.8.4 2002/01/04
3219 Scan for ZOOM API. New object ZOOM_scanset. New functions
3220 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3221 ZOOM_scanset_destroy.
3223 New ZOOM function, ZOOM_connection_last_event, that returns type
3224 of last event (such as "receive data", "send data", "apdu received",
3227 New ZOOM option, schema, that specifies schema for retrieval.
3229 New CCL feature. Qualifiers can be aliases for one or more
3230 other qualifiers (if more than one is given, OR is used).
3232 ZOOM uses named result sets if target supports it.
3234 Two new YAZ client commands: . (dot, which sources a script of YAZ
3235 client commands), and ! (to execute shell command.). Implemented
3238 Working on Debian packages.
3240 --- 1.8.3 2001/11/19
3242 YAZ client enables named result sets only if target supports it.
3244 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3246 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3247 with key="host" to get same result.
3249 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3250 Function Z3950_resultset_record(s) returns references to records
3251 "owned" by resultset. To become owner use Z3950_record_clone.
3253 Function z_ext_record handles Extended Services. Thanks to
3256 --- 1.8.2 2001/11/12
3258 CCL Parser fix: ignore token comma when dealing with and-lists.
3260 Documentation updates for COMSTACK.
3262 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3263 Changed prototype Z3950_records. For some functions, int parameters
3264 were changed to size_t.
3266 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3269 New MARC decode/display function, marc_display_exl, which properly rejects
3270 non-ISO2709 records. YAZ client uses it.
3272 --- 1.8.1 2001/10/29
3274 Fix bug: local attribute set wasn't set correctly in PQF strings.
3278 * Old Z39.50 codecs no longer supported.
3280 Added ZOOM C binding. See http://zoom.z3950.org/
3282 Renamed states for COMSTACKs to avoid confusion with events.
3284 Implemented cs_look and proper cs_rcvconnect.
3286 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3288 Configure detects POSIX threads on OpenBSD.
3290 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3291 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3293 When error is returned from present handler, non-surrogate diagnostic
3294 is returned in present response (and fetch handler is no longer called).
3296 * Minor adjustments to pquery parser (PQF). Token characters may be
3297 escaped by using backslash (C-style).
3299 PQF parser allows string attribute values to be specified. For @attr,
3300 non-numeric characters after the equal-sign are treated as strings
3301 (e.g. @attr 9=title).
3303 CCL trunction character may be defined (@truncation in file)
3305 * function zget_ExtendedServicesRequest sets waitAction to
3306 waitIfPossible (was wait).
3308 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3311 CCL operator names may be set in field definition files (CCL_bibset).
3312 See ccl/bib1 for an example.
3314 Fixes in ASN.1 compiler for C++ compatibility.
3316 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3317 and "op_or" to avoid conflict with C++.
3319 Fixed problem with GNU readline detection on Redhat 7.0.
3321 Added step-size for Scan backend handler.
3323 Fixed bug that made the frontend server crash when no attribute
3324 set was specified for scan.
3326 Front-end server automatically switches to original working directory
3327 when installed as an NT service. Previously -w had to be specified to
3330 Added extended attributes for retrieval module (data1), so that data1
3331 records carry d1_readXML/SGML attributes. d1_read also supports
3332 null-data rules ( <tag/>)
3334 On UNIX when POSIX threads are available, a separate library libyazthread
3335 is created. Programmers should link with that library and the yaz library
3336 when using threads. The reason for the split was that some applications
3337 on Linux, such as Apache, doesn't work well when using shared objects that
3340 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3341 (or any frontend server) in SSL mode by specifying ssl: followed by
3342 address. Only tested on UNIX.
3344 Added feature for CCL module. Virtual structure s=al or s=ol generates
3345 and-list and or-list respectively instead of phrase search.
3349 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3350 log_mask_str. This was done to avoid name conflicts with other libraries
3351 (such as other PHP extensions).
3353 Added raw OID member for preferred record syntax (request_format_raw)
3354 and returned record syntax (output_format_raw) for backend fetch method.
3356 Config file yaz-config now accepts options so that it returns specific
3357 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3359 Shared library support for UNIX using GNU libtool.
3361 * Modified backend interface. Request/Response struct's replaced by
3362 one read/write C struct. For example bend_fetchrequest and
3363 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3364 Every handler - even search has to be registered in bend_init
3365 handler. This means that the YAZ library no longer refers to
3366 external functions and it makes it possible to make the whole
3367 thing a single DLL/SO.
3369 Added Segment handler for backend server.
3371 Added Zmbol/Zebra administrative functions to YAZ client.
3373 Threaded frontend server on UNIX (when POSIX Threads are available).
3374 Starting the server with option -T enables multi-threading.
3378 Added configure option --enable-comp/disable-comp to control use
3379 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3380 located in sub directory asn.
3382 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3383 in ${exec_prefix}/bin along with the other programs yaz-client and
3386 GNU automake used to maintain makefiles.
3388 Added several OID's.
3390 Changed retrieval module so that we can load records with no abstract
3391 syntax defined. Tagpaths in these records are fully composed of string
3394 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3398 On UNIX, the generated makefile now supports a proper 'make install'.
3399 The prefix can be set via GNU configure to set the install location
3400 (default is /usr/local).
3402 * YAZ programs client and ztest were renamed to yaz-client and
3403 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3404 locations, such as /usr/bin,/usr/local/bin,etc.
3406 * YAZ Header files were moved from include to include/yaz. YAZ Header
3407 files are referred to as include <yaz/log.h> rather than <log.h>.
3408 The YAZ include path (-I ..) is therefore the same as before. Programmers
3409 should update their #include statements or use -Ipath/include/yaz
3410 instead. The main motivation for doing this change is that YAZ header files
3411 can be installed in "standard" locations /usr/include,/usr/local/include
3412 without introducing conflicts, since ALL YAZ header files are stored
3413 in subdirectory yaz (under /usr/include for example).
3415 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3416 rather than project/workspace files. We switched because project files
3417 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3420 Changed name of logging function, logf, to yaz_log, to prevent name
3421 clash with some math-log functions. The YAZ header log.h defines logf
3422 to yaz_log (#define) so there should be no incompatibilities by this
3425 Added bend_start/bend_stop handlers for server. These handler are
3426 called on start/stop of server. For windows they are called whenever
3427 a service is started/stopped.
3429 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3430 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3431 in util/yc.tcl. The auto-generated C code structures are, in a few
3432 cases, incompatible with the old decoders. There are differences in the
3433 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3434 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3435 The preprocessor variable ASN_COMPILED is defined when the compiled
3436 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3437 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3438 wish to use the old encoders/decoders you can specify --disable-yc
3441 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3442 version so that it supports both new - and old version of DB Update
3444 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3445 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3446 change. The name parameter can be set to 0 in which no name is specified
3447 for the construction. The macros odr_implicit and odr_explicit sets name
3448 parameter to zero for the construction involved. New macros
3449 odr_implicit_tag and odr_explicit_tag are similar to the others,
3450 except that a name parameter is added. For programmers' that don't use
3451 ODR they probably only need to change the call to z_APDU and z_External.
3453 Added access control facility by interfacing the TCP wrapper library.
3454 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3455 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3456 name of the daemon and enables the access control as specified in
3457 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3459 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3460 den Dool <H.M.vdnDool@kub.nl>.
3462 Added reference ID parameter to most functions in server API - refer
3463 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3465 Changed name of ccl library to libccl.a (was ccl.a).
3467 Fixed bug in decoder for Explain (Category TargetInfo).
3469 Added support for GNU readline in client. Thanks to Jacob Poulsen
3470 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3472 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3473 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3474 IMPLEMENTATION! This change was made to the development version before
3475 the ZIG decided to retract the amendment. If any users MUST be
3476 compatible with the original Update definition, PLEASE CONTACT US, and
3477 we will include a separate definition corresponding to the old Update
3478 ES. Note that because of the change to the ASN.1 of the
3479 TaskPackageRecordStructure we cannot define a single structure that
3480 will support both versions.
3482 * Added const modifier to buffer parameter for some ODR/BER encoding
3483 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3484 completeWAIS, odr_dumpBER.
3486 Fixed bug in client.c which caused a crash when a scanResponse didn't
3487 contain positionOfTerm.
3489 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3490 * will cause an error in a client if a non-YAZ target sends both a
3491 * list of Scan entries and non-surrogate diagnostics.
3493 Retrieval module enhancements. Tag sets may be typed in the reference
3494 to it. From the .abs-file the "tagset" directive takes a third optional
3495 integer type for the tag set referenced. From a .tag-file the "include"
3496 directive takes a third optional type as well. The old "type" directive
3497 in the tag set itself is still recognized but acts as the default type
3500 Backend interface change. Individual Scan terms returned from bend_scan
3501 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3502 in include/backend.h.
3504 Retrieval module enhancements. Multiple tag sets and attribute sets may
3505 be specified in abstract syntax specs. Revised the error/warning for
3506 logging messages reported by the retrieval module when reading the
3509 Object Identifier system (oid_..) changed. The API is backwards
3510 compatible but the oid-routines now allocates new OID's when needed.
3511 Raw OID's may be specified in oid_getvalbyname.
3513 YAZ now uses GNU configure to generate Makefile(s).
3515 * Minor changes in some of the member names of DeleteResultSetRequest and
3516 DeleteResultSetResponse. See include/proto.h.
3518 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3519 and added member 'languages' in TargetInfo (which was missing).
3521 Changed the way attribute sets are handled in the retrieval
3522 module. These are now cached, just like the abstract syntaxes
3525 Changed YAZ so that it links with compiled ASN.1.
3527 Added Explain-schema definitions and mapping routines. The following
3528 Explain categories have been implemented: AttributeDetails,
3529 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3531 Fixed minor bug in Windows version of Server Library.
3533 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3535 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3537 Added EXTERNAL: UNIverse Resource Report (non-standard).
3539 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3540 ENUMERATED and SET OF.
3542 * Added 'const' to some of the char pointer arguments for the
3543 functions, data1_read_node, data1_getelementbytagname,
3544 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3547 Fixed bug in data1_insert_taggeddata - the last_child member of
3548 parent wasn't initialised.
3550 * Changed data1_read_record and data1_read_node so that the supplied
3551 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3552 doesn't refer to any parts of the "SGML"-buffer.
3554 Fixed bug in server library (Windows version of statserv_remove).
3556 * Changed code so that it compiles as C++. The type definition
3557 of Odr_fun which is a member of Odr_arm was changed. The result is,
3558 that an explicit typecast is needed for the fun pointer when
3559 using Odr_arm - as in:
3560 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3562 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3564 Implemented the new structured date and time definition as approved
3565 by the ZIG. Added schemaId element to the specificTag in Espec-1
3566 (also approved at the last ZIG). Thanks to RVDM.
3568 Added some Object identifiers (RVDM).
3570 Changed the Update Extended Service (RVDM).
3572 Added command "refid" to client which specifies referenceId for
3573 the following requests.
3575 Implemented extended service handling for server. See ztest.c
3576 for an example as well as backend.h. New handlers are registerd
3577 in the Init handler.
3579 * Changed interface for sort in server.
3581 Added new members to statserv_options_block. It allows a server
3582 to read options from another source than just the command line. Thanks
3583 to Charles Woodfield.
3585 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3586 renamed to zboolean. Some C++ compilers complained about the name.
3588 Minor changes to gils.abs. Added index 's' (sort) on title
3589 and date/time-last-modified.
3591 --- 1.4pl2 1998/1/30
3593 Fixed bug in server library regarding inetd mode (-i). This bug
3594 was introduced by release 1.4.
3596 --- 1.4pl1 1998/1/29
3598 Added sort facility in client and backend server interface.
3600 Fixed problem with dependencies in Makefile(s).
3602 Fixed bugs for encoders/decoders of extended services and
3605 Implemented sub-tree feature for schemas. Sub-trees are
3606 referenced in *.abs-files. See explain.abs for an example
3607 of the use of this feature.
3609 Modified bib1.att; local attributes for ANY didn't include
3610 ANY itself (only affects use of the retrieval module).
3612 Fixed bug in plain SGML reader in function data1_read_node:
3613 tags with prefix "var" was incorrectly interpreted as variants.
3615 Added feature "sub-schemas" to enable references to - and definitions
3616 of - group of elements.
3618 * Removed member parent from type data1_element (in data1.h).
3620 Implemented function odr_nullval() that returns the value of
3623 * Removed member num_children from data1_node (in data1.h).
3625 Made NT service interface part of the server library. The
3626 function statserv_main uses the NT service when required and
3627 calls the statserv_start / statserv_close routines.
3629 Routine zget_SearchRequest and zget_PresentRequest fills
3630 resultSetName/Id member with "default" instead of "Default".
3632 Fixed memory leak in server. Request queue member wasn't freed.
3634 Fixed nmem_exit so that memory is freed.
3638 Revised the CCL parser utility to be thread safe.
3640 Added function, oid_ent_to_oid, to replace the function
3641 oid_getoidbyent, which is not thread safe.
3643 * Added nmem_init and nmem_exit to initialize and release
3644 NMEM resources. Function nmem_init should be called once in the
3645 initial thread before NMEM/ODR is used. statserv.c and client.c
3646 have been changed accordingly. The change was necessary to make
3647 NMEM thread safe. The NMEM memory pool is shared amongst threads
3648 in a process. Unix-based applications will still work fine without
3651 Added NT Services interface for the the Z39.50 (statserv) Server.
3652 Refer to the ztest.c source on the usage.
3654 Windows 95/NT port using MSVC5.0. Project files are included in the
3657 * Defined new 'global' handle for the retrieval (data1) system. The
3658 new handled, data1_handle, describes the state of the data1 system.
3659 This handle is passed as first argument to virtually all
3660 data1 related routines. The functions data1_create and data1_destroy
3661 creates and destroys a data1 handle respectively.
3663 Added ODR encode stream member to all backend request structures
3664 init, search, scan etc. This stream should be used to allocate all
3665 memory used for the response when thread safe operation is needed.
3667 Changed the comstack utility, cs_addstr, to be thread safe. The
3668 returned hostname string returned by the function is now part the
3671 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3672 function. The cs_straddr takes a COMSTACK handle as argument, so this
3673 function must be used after cs_create and before bind/connect.
3674 This function is thread safe.
3676 Moved test server to 'ztest' directory - generic server code still
3677 in 'server' directory.
3679 Made prefix query (pquery.c) utility thread safe.
3681 Added new function modifier YAZ_EXPORT to 'export' public DLL
3682 functions when using windows (see include/yconfig.h).
3684 Added definitions to the OID database (util/oid.c) (RVDM).
3686 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3688 Added call to ccl_rpn_delete in client program.
3690 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3691 release of RPN structure.
3693 Added support for C++, headers uses extern "C" for public definitions.
3694 With input from RVDM.
3696 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3697 Thanks to Ronald van der Meer (RVDM).
3699 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3701 Added support for private extensions to the OID database
3702 (oid_setprivateoids()). Thanks to RVDM.
3704 Added optional, physical ANY (key replication)
3706 Fixed null-reference problem in GRS-1 output filter.
3708 Proximity operator added to Prefix Query Format (PQF).
3710 In test client command "base" accepts multiple databases.
3712 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3716 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3718 Smallish bug-fixes in the new encoders/decoders (explain).
3720 Bug fixed in DeleteRequest.
3722 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3724 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3726 Added SOIF syntax (using private OID for now) to retrieval module and client.
3728 Added Update extended service.
3730 Added SearchResult-1 additional info structure.
3732 Added optional CCL (ISO8777) interpreter as separate module. Available
3735 --- 1.2 1996/6/10 (1st anniversary release)
3737 Added Summary record syntax. Lightly tested.
3739 Added OPAC record syntax. Untested.
3741 Added ResourceReport service encoders/decoders. Untested.
3743 Fixed bug in z_Unit - wrong tagging on unitSystem.
3745 Fixed bug in the DiagRecs decoder.
3747 Added options for max PDU size and session timeout to frontend-server.
3749 Added documentation of query-language parsers and other supporting utilities.
3751 [frontend-server] Added Attribute set to the bend_scanrequest API.
3753 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3754 surrogate diagnostics were generated.
3756 [retrieval] Allow multiple local values for attribute.
3758 [retrieval] Allow multiple attributes per element in .abs files. index type.
3760 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3762 --- 1.1pl2 1996/4/10
3764 Minor changes, mostly specific to Zebra's requirements (retrieval)
3768 Repaired bug in frontend server when running multiple listening
3769 endpoints in dynamic mode.
3771 z_External() now won't break if a known, ASN.1 value comes encapsulated
3772 in an octet-string. The value will pass through unmodified in an Odr_oct.
3774 Added a bit of code to the demo client to decode & display
3775 ASN.1-structured records represented in the octet-aligned branch of
3776 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3778 Added z_ext_getentbyref() to the ASN module. Doc updated.
3780 * Completed the SCAN definition in the ASN module. This may break SCAN
3781 code based on older YAZ-versions at compile-time. The fix is easy -
3784 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3785 under the SCAN definition. Remember to initialize this, server-people.
3787 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3788 that this does not extend to ODR and ASN.
3790 Comstack allows insertion of established socket (primarily for
3791 inetd-operation of servers). Doc updated.
3793 Front-end server can now start from the inetd in TCP mode. Doc
3796 --- 1.0pl4 1996/1/24
3800 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3801 the rank and record number.
3803 Adjustments to the frontend server.
3805 Fixed diagnostic BER dumper. It ignored the file argument.
3809 Various changes to retrieval module.
3811 Changed the union discriminators of the protocol files from enums to
3812 ints paired with #defines.
3814 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3817 *Changed operator in the RPN structure to 'roperator', again to avoid a
3820 Fixed problems in Explain decoders/encoders.
3822 --- 1.0pl2 1995/12/6
3824 Memory bug in log module fixed.
3826 --- 1.0pl1 1995/12/5
3828 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3830 Bug in Explain DatabaseInfo module fixed.
3832 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3836 The shift to v1.0 signals that we now consider the *core* functionality
3837 of YAZ reasonably stable (the core being more or less equivalent to
3838 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3839 tested (Explain not at all - though that will happen soonish).
3841 Minor changes to code to support Windows port.
3843 Various minor changes after we're getting to use GRS-1 & co. more.
3845 Added Espec-1 format.
3847 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3848 of the protocol and it cannot be selected when encoding (maps into 'string'
3849 when decoding). Needed to talk to some servers.
3851 Demo client can request simple element set names.
3853 Added Diagnostic Format encoders/decoders.
3855 Added simple Close handling to frontend server (no hooks for resource
3856 reporting yet), and demonstration client.
3858 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3860 --- 1.0b3 1995/08/24
3862 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3863 handled incorrectly when records were requested in the searchResponse. This
3864 will only affect you if you use the frontend-server.
3866 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3867 Test-client will ask for and print GRS1. Ztest will return dummy records
3870 Added Explain encoders/decoders to the service-level API. Untested.
3872 Added Extended Services: Item Order encoders and decoders to the Service-
3873 level API. Untested. We could use a recent copy of the pertinent bits
3874 of the ILL protocol to add those bits.
3876 Added diagnostic format 1 encoders/decoders to the service-level API.
3879 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3880 odr_cons.c, which causes a more correct output.
3882 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3883 was always set to 0 when no records were requested in the searchRequest.
3885 * Added better external-handling. This shouldn't harm old code that
3886 *encodes* externals. It can break code that looks for a
3887 'single-ASN1-type' representation, since those types that are known
3888 are now decoded immediately. Look at the SUTRS sample code in
3889 seshigh.c and client.c. Documentation updated.
3891 Handling of structured records in bend_fetchresponse. Length -1 marks
3892 structured record, type is deduced from format field.
3894 --- 1.0b2 1995/06/27
3895 Fairly quick maintenance release to add SUTRS support.
3897 Fixed handling of SUTRS records in the demonstration client.
3899 * Added format field to the bend_fetchrequest and bend_fetchresponce
3900 structures of the backend API (frontend server). When the record is
3901 returned, the value of the format field is mapped to an OID. The
3902 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3903 of the record. The special value VAL_NONE in the bend_request means
3904 that no specific format was requested by the client. Documentation
3905 updated accordingly. Test server (ztest) will return a fixed dummy
3906 SUTRS record if your client requests SUTRS.
3908 Documentation updated accordingly.
3910 You can now set external libraries and RANLIB support in the top-level
3914 First public release.
