3 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
4 with localtime_r when threads + fork is used (such as Metaproxy).
6 yaz-config: quote some RHS values (that might include blanks)
8 zoomsh: shows SearchResult-1
10 zoomsh: sortby command
12 zoomsh: use proper list of connections and result sets YAZ-725
14 Avoid yaz_log in sigterm handler for GFS YAZ-737
15 Logging is still performed, but outside sig handler.
17 New ZOOM C feature: result-set caching with memcached. Example:
18 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
20 Remove SSL via OpenSSL support YAZ-732
21 Also deprecate two functions from comstack that aren't working with
22 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
24 Revert "Bison: use %name-prefix directive rather than -p option"
28 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
30 SRU GET/Solr base URLs may hold additional ?args YAZ-729
31 ZOOM option extraArgs already does this, though. It seems useful
32 when dealing with Solr targets to limit by filter, eg.
33 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
35 Remove #fragment for HTTP request encoding YAZ-730
37 Doc: Update list of DLLs/LIBs
39 Doc: update href link to Unix utils and Git.
43 ZOOM: fix "lost connection" problem with servers that uses both squid
44 and another proxy behind it that returns Location headers with relative
47 zoomsh: do not use readline for stdin (no tty) YAZ-724
48 Just use fgets in that case. If the user hits Ctrl-D a new-line
51 zoomsh: empty command ignored YAZ-723
52 rather than performing exit of zoomsh.
54 yaz-url utility offers option -v to enable verbose mode.
56 yaz_url uses yaz_check_location and offers verbose mode.
58 Add new function yaz_check_location.
59 This function gets an absolute URI from Location (HTTP redirect).
61 cookie API: introduce yaz_cookies_reset
63 Update cql.y for newer bison YAZ-720
64 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
65 longer supported. Instead one must use %lex-param and %parse-param .
69 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
72 rpn2solr: support truncation left(2), left&right(3) YAZ-718
74 Mention SRU version 2.0 in yaz-client man page.
78 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
83 Make cs_parse_host public.A
85 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
86 introduced in YAZ 5.0.6.
90 Fix buffer corruption for yaz-ztest record fetch.
94 Allow yaz-ztest to return user-defined records (one record per file).
95 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
97 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
98 Use the stream write instead of odr_printf which has a 4K tmp buffer.
100 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
104 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
105 can read and write this format. For record format JSON, yaz-ztest returns
106 MARC-in-JSON records.
108 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
109 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
113 Improve error reporting for ICU chains YAZ-707
114 Report config element+rule when ICU status is "failure".
116 ZOOM: stop fetching if present response has no records YAZ-710
117 Some targets return less records than their hit count would suggest.
118 This prevents ZOOM from continuing to fetch records if any present
119 response has 0 records in the response.
121 Ensure that GFS calls exit if any listener fails YAZ-710
122 Before, if XML config was in use, it would start the default
127 yaz-ztest: -V shows version (like yaz-client -V)
129 New iconv encoding: danmarc YAZ-692
131 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
133 daemon: only wait for immediate child rather than all children. YAZ-704
135 yaz-client: fix setting of SRU record schema. If scheme was unset, it
136 could lead to invalid memory reference.
140 yaz-ztest returns schema for MARCXML test records. SRU require that
141 recordSchema for records.
143 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
144 instead of non-surrogate diagnostic. This is a per-record failure.
146 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
147 may refer to multiple listeners now. Attribute listenref is a comma separated
150 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
151 option is given for GFS, the dirname of filename (for -f) is used
152 as prefix for options such as cql2rpn, ccl2rpn, etc.
154 Content-Type charset fixes YAZ-701 . Do not inspect charset in
155 Content-Type header for SOAP when decoding SRU. The payload (XML)
156 itself tells what encoding it is. In response, never supply encoding
157 in Content-Type. The response payload (XML) tells what it is (with no
158 encoding in XML it's UTF-8).
160 HTTP decoding: allow blanks in URL paths YAZ-700
164 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
165 and facets. Ensure recordData and recordSchema are always present in
166 record element, because they are required.
168 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
171 Simplify in a lot of places using odr_strdupn.
173 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
177 Increase various buffers in GFS's statserv_options_block
178 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
179 This change makes many type-casts redundant, and, thus simplifies code.
181 Remove last bits of WAIS support.
183 Remove member 'size' from Odr_oct.
185 Slim down the public part of 'struct odr'. Most elements are not part
186 of struct Odr_private.
188 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
189 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
190 In particular facets are supported in both client - and server side.
191 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
192 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
193 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
194 both request/response). This is what a search handler in the GFS
195 will see (regardless of whether operating in SRU mode or Z39.50).
197 Changes to the srw.h (SRU/Solr) definitions include:
198 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
199 (char*), which replace union query and query_type (int). This is because
200 SRU 2.0 supports a queryType parameter. This also means that, to carry
201 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
202 x-pquery=PQFstring (extention parameter). The extension parameter
204 - New element, packing, that has information about SRU
205 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
207 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
209 New element, packing, in Z_SRW_explainRequest.
211 New elements in Z_SRW_scanRequest, queryType and scanClause.
212 These replace query_type and scanClase untion. This is similar to what
215 --- 4.2.69 2013/10/01
217 GFS: log when closing down - at least SIGTERM YAZ-684
218 Also change formatting WRT PID logging a bit.
220 Improve display of MARC records with multi-byte subfield IDs YAZ-695
221 In some rare cases subfield identifiers are multi-byte characters.
222 This will try to deterime length of those and split accordingly.
223 This affects display in line mode as MARCXML/MarcXchange. The encoding
224 of ISO2709 is the same.
226 Change inp argument to const for yaz_read_UTF8_char.
228 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
230 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
232 Better check of marc leader info YAZ-691
233 Problem is that some systems generate MARCXML/MarcXchange with
234 funny headers. These will not work if encoded as ISO2709.
235 Some tests produce new output, due to updated warning messages
237 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
239 yaz-client: display MAB records YAZ-689.
240 Thanks for Heiko Jansen for this patch.
242 New utility z_get_HTTP_Response_server which allows both HTTP server name
243 and HTTP server URL to be given in response.
245 Debian: do not depend on obs tcl8.3.
247 Debian: do not depend on obs libicu36-dev.
249 --- 4.2.68 2013/09/23
251 GFS: pass additionalSearchInfo to search memeber search_input if
252 given. Otherwise pass otherInfo. Request for facets and other search
253 related things will be passed there in future versions of YAZ.
255 New ZOOM setting, authenticationMode, which allows authentication
256 paramters to be encoded in the URL rather than via HTTP Basic auth.
259 rpn2solr: fix nested AND/OR handling. YAZ-685
261 Add comparison routines for some Z-types, such as NamePlusRecord,
262 RPNQuery, Query, RecordComposition and OtherInformation.
264 --- 4.2.67 2013/09/19
266 Don't decode MAB as MARC. Just like we don't attempt to decode
267 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
269 CCL: allow quoted terms for date ranges. YAZ-681
271 Introduce ccl_parser_qual_search. This function makes old function
272 ccl_qual_search, from YAZ 2, available again.
274 Add yaz_facet_list_to_wrbuf. YAZ-683
276 --- 4.2.66 2013/09/11
278 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
279 schema was given for search. YAZ-675
281 Add Solr date range searches. YAZ-621
283 --- 4.2.65 2013/08/22
285 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
287 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
289 ISO2709/MARC parse most octet aligned records; not just those that
290 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
291 MARC parse more records instead of just dumping as is. YAZ-670
293 ZOOM: proper caching for variations of record schema. YAZ-671
295 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
297 --- 4.2.63 2013/07/17
301 --- 4.2.62 2013/07/11
303 New utility z_get_HTTP_Response_details - an extended version of
306 New utility yaz_url_get_error which returns error message of last
307 failed yaz_url_exec call.
309 yaz-url and url functions: allow max HTTP redirects to be controlled.
311 New functions yaz_file_glob2, yaz_xml_include_glob.
312 These functions takes a flags parameter, which, for now only controls
313 whether to fail inclusion of a non-existing file (without glob
314 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
316 --- 4.2.61 2013/06/20
318 For MARC XML parsing, allow record without leader. A fake/default leader
319 is inserted and a warning is tagged with the record.
321 ICU: fix leak in in icu_iter_get_org_info.
323 --- 4.2.60 2013/06/14
325 ICU: fix bug in icu_iter_get_org_info (un-init variable).
327 --- 4.2.59 2013/06/11
329 Implement z_HTTP_header_remove.
331 --- 4.2.58 2013/06/11
333 ICU: Disallow 0 ptrs for some ICU string utilities.
335 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
336 returns original tokens (before normalization).
338 CCL: avoid z39.58/regex truncation when not needed. Apply only the
339 conversion of those masks, when absolutely necessary.
341 CCL: configurable masking character - @mask. Default masking character
344 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
345 full response anyway, so a Transfer-Encoding header will obstruct the
348 --- 4.2.57 2013/05/15
350 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
351 picking a socket. Problem is that some systems has IPV6 support, but
352 we can't create sockets for them, so we pick AF_UNSPEC first.
354 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
355 use content_len to determine resulting Content-Length in HTTP response
356 and NOT Content-Length supplied in headers by user.
358 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
359 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
361 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
364 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
365 with big endian and unsigned char (by default).
367 --- 4.2.56 2013/04/26
369 Fix yaz-client connect (crash in 4.2.55).
371 --- 4.2.55 2013/04/26
373 Fix proxy/host problem for ZOOM that could occur if unix sockets
376 New Debian package libyaz4-dbg.
378 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
379 differently in tcpip_close.
381 --- 4.2.54 2013/04/17
383 Windows installer of YAZ includes YAZ4J as a component.
385 CQL: allow "extra terms" again, by default. Thus, the CQL parser
386 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
387 and earlier. CQL parser may operate in strict mode where queries
388 not conforming to the standard BNF are rejected (syntax error).
389 Whether the CQL parser operates in strict mode is controlled with
390 cql_parser_strict . Strict mode enabled with option -S for utilities
391 cql2pqf and cql2xcql .
393 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
395 --- 4.2.53 2013/04/10
397 New charset, MARC-8c, which is like MARC-8 but allows control characters
398 0x01 through 0x1F, except ESC to be passed through verbatim.
400 Fix a problem with duplicate sub field character in MARC output. Problem
401 happened only when output was MARC-8 encoded.
403 --- 4.2.52 2013/04/03
405 yaz-ztest: Use hash for fake hit count. Before, random number was used.
406 This is problematic for unit tests using yaz-ztest. This patch also makes
407 a hash for CQL queries. For RPN, any term with a leading digit will be
408 treated as pseudu hit count (to force any particular hit count by a client).
410 yaz-ztest: return unique MARC dummy records. Beyond record offset
411 24, the author surname is patched with offset to make all records
414 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
415 on system wide default (/proc/sys/net/ipv6/bindv6only).
416 @4 binds to IPV4 only. @6 binds to IPV6 only.
418 Update CQL API documentation a bit
420 CQL: don't accept extra terms for queries. Makes the CQL parser
421 stricly conformant to the standard.
423 --- 4.2.51 2013/02/12
425 GFS: scan handler gets extra_args from request and may return extra
426 response data . That's for SRU only.
428 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
430 --- 4.2.50 2013/01/30
432 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
434 OPACXML: sync spelling of availabilityDate in XML to that of Schema
435 opaxxml.xsd. The schema had the correct spelling of this member always.
436 The ASN.1 was mis-spelled and still is (API change) - we are
437 not changing this. However, the OPAC to XML conversion had yet
440 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
443 New function, z_ext_record_oid_nmem, which is similar to
444 z_ext_record_oid but takes NMEM rather than ODR
446 --- 4.2.49 2013/01/18
448 ICU: New conversion element 'join' which joins tokens into one
449 with a custom character given by rule attribute.
451 --- 4.2.48 2013/01/10
453 New GFS search member: present_number. This is a hint to the
454 search handler how many records are going to be fetched immediately
455 following search. There's no guarantee that it's going to be the case,
456 since it depends on hit count (for Z39.50 piggyback) and whether errors
459 Make a few functions static (private). The functions getbyte_stream,
460 ungetbyte_stream and yaz_gets are now private. They were never declared
463 yaz-marcdump: exit(5) for serious decoding errors
465 ISO2709 decoding: be more picky WRT header
467 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
468 was only used as to indicate that next-result-set-position should be
470 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
471 Based on patch from Ashley Sanders.
473 Make some functions static/private in PQF parsing. Those functions were
474 never declared in a public header and so should not be in use by
475 applications based on YAZ.
477 --- 4.2.47 2012/11/23
479 ZOOM: special options to control APDU logging.
480 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
481 logging of APDUs until "saveAPDU" option is set again. If logging is
482 already enabled the effect is that current APDU buffer is cleared.
483 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
484 logging (default behavior on new connection).
485 The APDUs sent/received can be obtained by using
486 Using ZOOM_connection_option_get(c, "APDU") or
487 ZOOM_connection_option_getl(c, "APDU", &l).
489 GFS: relay implementation_version from backend
490 From 3.0.40 and later, implementation_version from backend was
491 not used in init response at all.
493 --- 4.2.46 2012/11/15
495 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
496 mode at all. Probably never did.
498 Make a new version of ztest.pem that, at least, is not expired.
500 --- 4.2.45 2012/11/13
502 Fix description of CCL directive 'case'.
504 More tight checking of form arguments (yaz_uri_to_array). Makes
505 YAZ better at rejecting big and/or bad POSTs.
507 SRU decoding does not report more than up to 10 invalid arguments.
509 rpn2cql: less quotes in generated terms. Semantics unchanged, but
510 it's prettier this way.
512 --- 4.2.44 2012/10/25
514 New utility yaz_decode_init_diag. Defined in proto.h.
516 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
517 given for unix local socket.
518 The COMSTACK string for doing so is:
521 unix:/myfile:tcp:localhost:9999/mybase
522 unix:/myfile:localhost:9999/mybase
523 unix:/myfile:http://fakehost/mybase
525 debian: Use dpkg-buildflags in build process.
527 --- 4.2.43 2012/10/19
529 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
530 global's SRU service uses a recordPosition scheme starting from zero.
531 First record's position should be one
532 according to the standard.
534 --- 4.2.42 2012/10/18
536 Allow more namespaces for SRU. This is to allow, for example, an
537 incorrect namespace returned from server
538 http://services.igi-global.com/sru .
540 Minor fixes for compilation on Windows.
542 --- 4.2.41 2012/10/11
544 daemon: log total number of bad signals from child on stop so that it
545 is more easy to spot problems with child worker processes.
547 retrieval: empty backend name attribute omits element set
548 from being used in retrieval.
550 --- 4.2.40 2012/10/04
552 Implement Solr sort strategy "solr", similar to sru11 sorting.
553 This will implement the correct parameters on Solr requst to do
556 --- 4.2.39 2012/09/28
558 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
561 MARC: Extra/missing indicator handled for MARCXML.
562 The indicator length is given in header and is the same for the
563 whole record. If attributes ind1, ind2 are missing, then content
564 character defaults to blank. Extra indicator attributes (beyond)
565 indicator length are treated as an error.
567 Reformat: delete trailing whitespace
569 --- 4.2.38 2012/09/17
571 MARC: fix non-ASCII characters for leader. This is to ensure we can
572 generate XML in UTF-8.
574 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
575 in one node with structure word.
577 --- 4.2.37 2012/09/04
579 yaz-json-parse: JSON output may be pretty printed by using option
582 Increase default value of max message for Z39.50 Init for GFS, ZOOM
583 and yaz-client. Old value was 1 MB. New value is 64 MB.
585 --- 4.2.36 2012/08/22
587 yaz-client: don't display bogus records from SRU servers. Some SRU servers
588 return more records than given by *maximumRecords*. Skipping those in
591 record_render: simplify buffer return handling and fix at least one bad
592 memory reference, that broke the test_embed_record sometimes.
594 Allow http://user:pass@host notation for yaz_url_exec.
596 zoomsh: allow shell command to be executed. Via the system(3) call.
598 yaz_poll: Allow num_fds == 0
600 yaz-client: fix bad encoding of "itemorder item". The itemorder
601 item <no> - command forgot to use length of encoded Item Request
602 package. Error present since YAZ 3.
604 yaz-ztest: fix bad usage of session handle. Bug was introduced when
605 result sets were saved (271a9c83).
607 SRU recordPacking: guess record packing in response rather than looking
608 at the recordPacking element which, OF COURSE, changed semantics in SRU
611 Decode SRU 2.0 responses. The official namespace for responses, according
612 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
613 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
614 nature.com's server, however, usee namespace
615 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
616 we are now using a glob-expr to match up the namespace. ZOOM C and
617 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
618 I can not find a single real example showing the "real" namespace in
619 the documentation from OASIS. The namespace for requests is different
620 from responses, but this is not added to YAZ yet, when we don't encode
623 --- 4.2.35 2012/06/26
625 zoom/record_render: add support for Base64 decoding fo MARC records
626 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
627 which will decode base64 + ISO2709 marc-8 encoded material from text node
630 --- 4.2.34 2012/06/07
632 Add missing definitions ZOOM_resultset_get_facet_field_by_index
633 and ZOOM_resultset_facets_names.
635 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
638 Change APDU dump printing to avoid long leading blanks. For levels 16
639 or larger the level is shown and the indentation is truncated but
640 recursed with modula 8. This makes it still reasonable easy to read
641 - even for nested BER dumps.
643 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
644 return 0 (incomplete package) in case where the BER package was
645 considered too nested (return value of -2).
647 dumpber: lines of level 15 are not indented further. Two spaces per
648 indentation; indentation 15 or more is indented to a fixed indentation
649 and augmented with a level=<no> indication.
651 zoomsh: increase max size of command+args
653 GFS: No limit in RPN buf size in CQL to RPN conversion.
655 --- 4.2.33 2012/05/09
657 New function for daemon utility, yaz_daemon_stop .
659 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
661 --- 4.2.32 2012/04/25
663 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
664 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
666 --- 4.2.31 2012/04/23
668 YAZ daemon utility relays SIGUSR1 to child process.
670 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
671 would result in en empty database list - which in turn would result in
672 encoding failure for search.
674 Fix reading beyond string in yaz_sort_spec.
676 --- 4.2.30 2012/04/11
678 Add two new SRU diagnostics:
679 236: Access to specified database denied
680 1015: Init/AC: Maximum number of simultaneous sessions for Userid
682 Document the very useful ZOOM-C option "apdulog".
684 CQL to RPN: term may be passed through verbatim. This is enabled with
685 truncation.cql . The assumption being that the term is already CQL.
687 --- 4.2.29 2012/03/20
689 record_conv: leader spec may be given for marc element.
690 The leader spec is given as attribute leaderspec for element marc.
691 For example to convert a MARC21 record from MARC-8 to UTF-8:
692 <marc inputformat="marc" outputformat="marc"
693 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
695 record_conv: allow user-XSLT params. For example:
696 <xslt stylesheet="MARC21slim2DC.xsl">
697 <param name="myparameter" value="myvalue"/>
698 <param name="otherparameter" value="othervalue"/>
701 record_conv: fix error handling for missing marc charsets.
703 CQL: fix extra terms in wrong order.
705 --- 4.2.28 2012/03/06
707 record_conv: modify new API for conversion types. The conversion types
708 may be passed in new functions yaz_record_conv_configure_t and
709 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
711 Avoid mixed statement/variable declare; fixes compilation with Visual
714 --- 4.2.27 2012/02/28
716 Add non-standard SRU diagnostic: 235: "Database does not exist".
717 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
718 Update SRU to Bib-1 diagnostic maps accordingly.
720 CCL: add two new diagnostics for unsupported masking. The new
721 diagnostics are: "Embedded truncation not supported" and
722 "Single charcacter mask not supported".
724 --- 4.2.26 2012/02/23
726 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
728 --- 4.2.25 2012/01/11
730 Build YAZ for Ubuntu Oneiric.
732 CCL: allow parantheses for proximity operands. For example CCL query
733 (a) % (b) is now allowed.
735 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
736 marked dead, rather then being destroyed. If not, the session memory is
737 being free'd before the search/scan handler is finished. Also destroy
738 'request' memory in request_release rather than in various places,
739 which resulted in leaks from time to time.
741 --- 4.2.24 2011/12/21
743 cql_sortby_to_sortkeys: honor sort prefix.
745 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
746 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
747 The rpn2cql family of functions now always returns quoted CQL terms.
749 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
751 --- 4.2.23 2011/12/15
753 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
754 sequence is treated as one. For example, &&a=b&&&c& is identical to
757 --- 4.2.22 2011/12/05
759 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
760 APDUs for a connection to a WRBUF.
762 --- 4.2.21 2011/11/23
764 Fix cql_sortby_to_sortkeys. Completely broken before.
766 Make CCL's @truncation work again.
768 --- 4.2.20 2011/11/09
770 New ZOOM connection setting: tproxy. It's like proxy, but does not
771 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
772 to set resolved address + port for a connection outside ZOOM itself.
774 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
776 --- 4.2.19 2011/11/07
778 Fix uninitialized variable in Solr spell support (could cause SEGV
779 for SRU response decoding).
781 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
782 back-end's addinfo through into the ZOOM response addinfo.
784 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
785 they are separated by a colon and a space rather than simply
788 --- 4.2.18 2011/10/28
790 Add support for Solr spell-checking/suggestions through ZOOM.
791 If a Solr target has been configured correctly for spelling-checking
792 and suggestions, these will now be returned on the ResultSet option
793 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
795 --- 4.2.17 2011/09/28
797 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
798 with a flag whether to substitute escape sequences or not.
800 --- 4.2.16 2011/09/22
802 Fix nmem_strsplit_escape to substitute escape char properly.
804 New option for zoomsh -e , which makes it abort on first error and
805 return process exit code to indicate success/failure.
807 YAZ options utility supports special option -- which makes all it treat
808 all following arguments as non-options.
810 --- 4.2.15 2011/09/16
812 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
813 searched if absolute filename is given.
815 Fix conv_xslt() error-reporting when stylesheet is not found.
816 (The value of fullpath is meaningless in this situation.)
818 --- 4.2.14 2011/09/07
820 Fix problem in CQL sort node creation: un-initialized memory.
822 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
823 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
824 CQL sortby depending on whether Type-1 or CQL is actually sent to the
827 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
828 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
830 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
831 will make it possible to use both single-character mask (#) and wildcard (?)
832 in CCL . Throw diagnostic for left truncation because that is not supported
835 --- 4.2.13 2011/09/01
837 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
838 cases using escapes (\-sequences) and masking.
840 PQF parse fix: A trailing backslash followed by end-of-string (\0)
841 would result in a read one byte beyond string.
843 rpn2ccl may use Z39.50 masking for terms (t=z).
845 ICU check fix. Don't include library -lCrun on Solaris, unless present.
847 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
848 not --cppflags (which seeems like an error in icu-config).
850 --- 4.2.12 2011/08/27 RPM package only
852 cql2ccl: fix conversion of terms: operator characters were not
855 --- 4.2.11 2011/08/25 RPM package only
857 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
858 CCL parser will map both # and ? to their regular expression
859 quivalents (. and .*).
861 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
862 of reserved CQL characters.
864 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
865 is, so that they are passed through.
867 --- 4.2.10 2011/08/24
869 ZOOM SRU mode: more aggressive re-connect.
871 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
872 made available as a utility function, declared in <yaz/logrpn.h>
874 rpn2cql_structure() supports proximity nodes (except that the Type-1
875 proximity node's "exclusion" binary is ignored, as there is no way to
876 express that in CQL). Fixes bug #4564.
880 Fix SEGV that could occur if set command of zoomsh was given without
881 value (2nd argument).
883 Fix SEGV that could occur if unsupported transport was given for
884 COMSTACK - say https (when SSL was unavailable).
886 Build yaz-url on Windows too.
890 New utility to get web content. Header is url.h. A command line tool
891 yaz-url is part of the distribution and packages.
893 Fixes for SSL COMSTACK (when gnutls is in use).
895 New functions yaz_base64{encode,decode}. Header is base64.h.
899 ZOOM C includes HTTP response buffer as additional info if it fails
900 to decode the SRU response.
902 Make wrbuf_json_puts available.
906 zoom: throw diagnostic for invalid value for option "sru". Before a
907 bad SRU request was sent.
909 Adding new utility wrbuf_vp_puts.
911 Add cclxmlconfig.obj to win/makefile. It was missing completely.
915 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
916 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
917 redirect was used at the same time.
919 MARC line mode decoding: be less picky about length given - first
920 5 digits of header that is.
922 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
924 Changes to decoding of SRU records: a record with recordPacking=xml is
925 modified with a new root element <yaz_record> if the recordData contains
926 multiple children elements. This is to make the record XML parseable
929 RPN to Solr conversion: encode special characters.
931 Generic Frontend Server: fix uinitialized member, stepSize.
935 Fix a bug in SRU decoding of records.. The database records stored
936 had un-initialized memory, but it would only be seen with yaz_record_render
937 and type_spec="ext" .
939 Fix a bug in ccl_qual_dup introduced in 4.2.3.
943 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
947 Add new utilities to convert from CQL to CCL . These utilities have
948 prefix cql_to_ccl defined in cql.h.
950 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
951 lead to memory heap corruptions when ICU utilities were in use.
955 Make compilation work without Libxml2.
957 yaz-client: remove redundant blanks in display of searchResult-1 term
962 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
963 resulting CQL node (tree) in a new node CQL_NODE_SORT.
965 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
966 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
967 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
968 Note that the CQL sortby spec is only converted when the GFS is already
969 converting from CQL to RPN (cql2rpn element).
971 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
972 specify whether to collapse delimitors or not. The existing nmem_strsplit
973 do collapse (collapse parameter = 1).
975 Windows installer: For NSIS, set InstallDir depending on x86/x64.
977 Rename internal func yaz_use_attribute_create. While non-static, this
978 function is not declared in a public header.
982 Add -lCrun when linking with ICU on Solaris.
984 More quicks character set conversions for OPAC records.
988 fix problem with record_render: records were converted (character set
989 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
993 SRU: add methods for handling DADS SRU-proxy facets.
995 Separate OPAC record character set for ZOOM_record. yaz_record_render
996 allows a character set given as charset=from/opacfrom,to where 'from' is
997 the character set of a bibliographic record, 'opacfrom' is character set
998 of OPAC record and 'to' is the target character set.
1000 --- 4.1.4 2011/02/21
1002 yaz-client: show may XML format records. Command show followed by 'format'
1003 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1006 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1009 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1011 --- 4.1.3 2011/01/27
1012 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1014 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1015 this package can be distinguished from other vendors.
1017 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1018 as determined by configure
1020 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1022 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1023 returns no error and no record, the present request is considered
1024 partial (only a subset of the records could be returned by backend), and
1025 so it is appropriate to set Present Status to partial-4.
1027 --- 4.1.2 2010/11/02
1029 Move yaz-config man pages to section 1.
1031 More documentation about Solr.
1033 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1034 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1035 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1036 peers on some Linux systems. However, in general that does not work
1037 so YAZ can not rely on that to work. Debian changed behavior in this
1038 respect from Debian lenny to Debian squeeze (still testing as of Oct
1040 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1042 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1044 --- 4.1.1 2010/10/05
1046 Fix yaz-config output: echo_source not set correctly by configure.
1048 --- 4.1.0 2010/10/05
1050 Solr Web Service support for yaz-client and ZOOM.
1052 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1054 --- 4.0.12 2010/08/17
1056 Z39.50 facet support. Facet specifications are passed for search in
1057 other-information with ASN.1 as defined in facet.asn and OID
1058 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1059 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1060 3 is limit (number of entries to get in response). yaz-ztest returns
1061 dummy facets if a client asks for them.
1063 --- 4.0.11 2010/07/09
1065 CCL fixes: bug 2895 and bug 3539.
1067 GR1-display: add comma in display - was removed by mistake in
1070 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1072 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1074 --- 4.0.10 2010/06/18
1076 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1077 result set from a connection. The result set will be on its own
1078 thereafter; no operations on it will perform retrievals from a target.
1079 Only cached copies are returned.
1081 ZOOM C:fix case for HTTP servers responding with Connection:close.
1082 Ensure that if there is a current task it is resumed (like fetching
1083 more records in a result set) . Bug #3484.
1085 PQF parser: use odr_atoi for Odr_int (not atoi)
1087 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1088 values that contain any non-digits are treated as string attributes
1089 (previously decoding only checked for leading character ([0-9]). PQF
1090 encoding: attribute string values are not surrounded by double-quotes.
1092 --- 4.0.9 2010/05/21
1094 New utility for managing threads - thread_create.h.
1096 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1097 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1098 but YAZ' implementation do.
1100 Fixes for yaz_cond-functions on Windows 7.
1102 DLL export more symbols.
1104 zoomsh: show record do NOT render opac.
1106 Remove *.la files from Debian and RPM packages.
1108 --- 4.0.8 2010/05/11
1110 Debian package libyaz-dev depends on libgnutls-dev again (was
1111 removed in YAZ 4.0.6, but due to Libtool it is still needed
1112 even though yaz-config do not list libgnutls libs).
1114 ZOOM: Use only one WRBUF for returning string results for
1115 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1117 ZOOM: ZOOM_connection do not use a shared pointer to
1118 ZOOM_resultset after ZOOM_resultset is destructed by
1119 user. Reverts to YAZ 4.0.4 behavior.
1121 --- 4.0.7 2010/05/04
1123 record-conv: fix problem with at least one XSL conversion -
1124 due to probably incorrect usage of XML XSL documents.
1126 --- 4.0.6 2010/04/29
1128 Fix yaz-config for static mode and the use of SSL (gnutls).
1130 --- 4.0.5 2010/04/29
1132 Forward decl timeval struct in mutex.h and gettimeofday.h.
1134 yaz-config: fix 'static' mode linking.
1136 --- 4.0.4 2010/04/28
1138 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1139 are wrappers for pthreads or Windows. For Windows these are put in
1140 a separate DLL: yaz_cond4.
1142 libyaz.la (whole source) is compiled with thread. If thread support
1143 is enabled enabled, all source of YAZ is compiled with treading support.
1144 This allows core utilities such as yaz_log to use thread facilities.
1145 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1146 thread utilities. This commit moves mutex utilities (mutex.c) from
1147 libyaz_server.la to libyaz.la.
1149 yaz-json-parse displays leading text until error.
1151 --- 4.0.3 2010/04/09
1153 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1154 patch from Giannis Kosmas.
1156 SRU: no longer URL encode SRU database. The URL for an SRU server is
1157 a URL and such is alreeady encoded - at least when given with leading
1158 http:// or https://. This reverts behavior to YAZ 3.0.50.
1160 Support for new MARC XML notation TurboMARC which like MARCXML is a
1161 complete representation of MARC/ISO2709.. This one, however, is more
1162 compact and allows for faster processing with XSLT. TurboMARC can be
1163 used in the marcdisp.h API, from the yaz-marcdump utility and from
1166 yaz-ztest can be configured - via the database - to perform certain
1167 delays when it performs operations search, present and single record
1168 fetch. This allows testers to make yaz-ztest act as a real or even slow
1169 Z39.50 server. Refer to the yaz-ztest man pages for details.
1171 --- 4.0.2 2010/03/09
1173 wrbuf_destroy allows NULL WRBUF passed to it.
1175 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1177 Add ZOOM_connection_close.
1179 No fixed size buffers for ZOOM shell - bug #3257.
1181 tstodr: make it work on s390 platform.
1183 New icu iterator-functions. The new icu_iter-functions makes it possible
1184 to use ICU chains from many threads.
1186 yaz-client: better syntax check for show command.
1188 --- 4.0.1 2010/01/26
1190 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1193 New simple local-file XML include facility which allows file glob-patterns.
1194 Refer to yaz/xml_include.h.
1196 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1199 ZOOM_record_get supports new parameter "format" which makes it format XML
1202 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1203 JSONText in ECMA-262) is JSONValue, not JSONObject.
1205 --- 4.0.0 2010/01/20
1207 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1208 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1210 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1211 POSIX/Unix builds .so with major version 4.
1213 Remove old LOG_-defines from log.h. They have been obsolete and
1214 undefined by default for the last 5 years.
1216 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1218 GFS: Remove socket (int *fd) from search_rr handler. The socket
1219 descriptor ptr is a facility that allowed a search handler to supply
1220 a socket which would serve as a callback - when search was complete.
1221 This facility has now been in use for years.
1223 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1224 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1225 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1226 returns 'const char *' rather than 'char *. The returned string is
1227 read-only and should not be modified by applications. COMSTACK cs_close is
1228 now a void function - it no longer returns int. No applications check for
1229 the value and the implementations has always returned 0.
1231 ZOOM: use size_t for scan hit counts and str size. Functions
1232 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1233 occ (hit count) and len (string length) are now of type size_t pointer
1234 rather than int pointer. This is to be able to represent large hit counts
1235 and to also just to use the proper type for string length (strlen result).
1237 New JSON parser. Refer to include/yaz/json.h .
1239 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1240 Used to be int in some cases. Many wrbuf_-functions used to return an int
1241 indicating some length.. These return values were never used. And so they
1244 ODR: odr_malloc, odr_total now takes size_t for size.
1246 clone_z_type: fix leak; occurred for encoding failures.
1248 --- 3.0.52 2009/12/03
1250 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1251 bug was introduced in 3.0.51.
1253 --- 3.0.51 2009/12/02
1255 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1257 tcpip comstack: fix leak for getaddrinfo.
1259 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1260 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1261 Decoding of SRU "path" database is performed by private function
1262 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1263 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1265 yaz-client: honor base command for SRU. Change when database setting
1266 is applied for SRU and ensure it is kept when a connection is reset.
1267 Change also the way errors are displayed or SRU (decoding of packages).
1269 --- 3.0.50 2009/11/02
1271 Add support for extra request / response data for SRU codecs and GFS.
1272 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1273 for extra data response buffer and length. For the GFS, both request
1274 and response data (XML) is carried in extra_args and extra_response_data
1275 for the search handler. Patch by Ko van der Sloot.
1277 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1278 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1279 10010). This fixes bug #2113.
1281 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1282 cmdfile included a 'quit' command that would result in a memory violation.
1284 --- 3.0.49 2009/10/01
1286 Make a number of functions defined in xmlquery.c static. These have
1287 never been declared in a public header file (yaz/xmlquery.h) and was
1288 made public by mistake.
1290 Improve speed of character conversions (iconv utilities). This makes
1291 conversions from MARC-8 faster.
1293 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1294 unless type desired is "raw". This will prevent type "xml" from
1295 returning ISO2709 .. Which obviously can not be XML parsed.
1297 Fix memory leak in ZOOM that would occur if option apdulog was used
1298 on a re-used connection.
1300 Frontend server logs HTTP requests.
1302 Frontend server now sends Z39.50 close when it times out (sesssion has
1303 been idle for too long). Versions 2.0.30 and earlier also sent close.
1304 But due to a mistake this was disabled in all versions after that, i.e.
1305 the server would just close the socket immediately.
1307 yaz-client emits a better message when receiving an unrecognised
1308 userInformationField.
1310 Skip zero-length subfields when decoding ISO2709. This rare case happens
1311 if a record has two FS characters in a sequence. Without this patch
1312 there would be a reference beyond char array in using_code_len fragments
1315 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1317 --- 3.0.48 2009/08/28
1319 The show command offered by the zoomsh command now takes a 3d optional
1320 parameter type which is what is passed to ZOOM_record. If the type
1321 argument is omitted, "render" is used.
1323 RPN to CQL conv may use USE string attributes (bug #2978).
1325 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1327 --- 3.0.47 2009/07/08
1329 Function yaz_xml2query allows a diagnostic element in the PQF XML
1330 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1331 code and additional info respectively.
1333 The BER BOOLEAN is now the integral type Odr_bool which still happens
1334 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1335 typedef'd to Odr_int. This is still an integral 'int', but it may be
1336 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1337 ASN-1 compiler as well as programs has been updated to use the new types.
1339 --- 3.0.46 2009/06/08
1341 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1342 only the bibliographic record was rendered. For type=opac, an OPAC
1343 record is only returned if it is present.
1345 iconv: small fix for encoding of advancegreek.
1347 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1349 yaz-client: option auto_reconnect=on really reconnects.
1351 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1353 server: avoid null ptr ref for for yaz_poll errors.
1355 build: fix RPM build for RHEL 5.3.
1357 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1359 --- 3.0.45 2009/03/31
1361 Fixed bug #2709: TCP connect returns Invalid argument.
1363 Fixed compilation for mingw.
1365 Honor charset for raw records (ZOOM_record_get).
1367 Fixed use of errno for threaded mode that was seen on Solaris 10.
1369 Fixed argument passing with blanks in value for Windows Service.
1371 Disable YAZ' own log rotate by default (no 1 GB limit).
1372 The variable l_max_size which specifies the log file limit is set to 0
1373 (DISABLED): This is due to the fact that YAZ is most often deployed using
1374 logrotate. Also YAZ can not perform log rotate because of unsufficient
1375 permissions (setuid).
1377 --- 3.0.44 2009/02/17
1379 List supported encodings in man page for yaz-iconv.
1381 Fixed missing SSL libs for --libs output
1383 Re-established OID record syntax application-xml. Nobody should use it
1384 but we don't want to change soname because of this symbol being absent.
1386 --- 3.0.42 2009/02/02
1388 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1390 Added member named_result_sets for init handler struct for the GFS. This
1391 allows a server to disable named result sets.
1393 Removed OID record syntax application-xml.
1395 Added support for rule-based transliterator for ICU wrapper of YAZ.
1397 Fixed bug #1902: yaz-icu XML output.
1399 Make YAZ checks Emacs friendly.
1401 BITSTRING value shows value. Bug #2346.
1403 ISO2709 decoding: skip control characters from indicator data.
1405 Omit sort key by default in yaz-icu's output.
1407 Allow combined single char options (again) for YAZ' options function.
1409 Utility yaz-marcdump got option to display YAZ version (-V).
1411 Allow YAZ to use ICU 3.4.
1413 Added new ICU test case which illustrates removal of diacritics.
1415 --- 3.0.41 2008/12/29
1417 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1419 --- 3.0.40 2008/12/29
1421 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1424 Fixed bug #2352: yaz-marcdump crashes for certain record.
1426 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1428 Added support for Danmarc2 to UTF-8 conversion.
1430 Added support for ISO5426 to UTF-8 conversion.
1432 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1433 implementation version.
1435 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1437 --- 3.0.38 2008/11/10
1439 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1440 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1442 ZOOM C now interprets databaseName option for ZOOM connection as path
1445 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1447 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1449 Dummy Libxml2 types no longer defined in headers of YAZ'.
1451 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1454 --- 3.0.36 2008/09/26
1456 Various ODR chapter fixes.
1458 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1460 Added missing source for Windows compilation, mutex.c.
1462 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1464 For SRU connections in ZOOM all records up to "count" are now fetched.
1466 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1467 in Windows due to bad error handling for Libxml2.
1469 Added facility for sending arbitrary records (ASN.1 any) using
1470 ZOOM C's Extended service update. Patch by Sam Reynolds.
1472 New options for ZOOM C's connection, logapdu which makes ZOOM log
1475 --- 3.0.34 2008/06/18
1477 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1479 --- 3.0.32 2008/06/12
1481 Fixed memory violation that could occur when decoding UTF-8. This bug
1482 was only present in 3.0.30 of YAZ.
1484 --- 3.0.30 2008/06/06
1486 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1487 GNU TLS is used by default (if found).
1489 yaz-ztest returns OPAC records if a client asks for OPAC.
1491 Improved speed of MARC-8 encoding.
1493 Added support for lossy and loss-less MARC-8 encoding.
1495 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1497 Added new Windows Service wrapper (sc).
1499 yaz-client's itemorder command may now send a file.
1501 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1503 Added new function yaz_log_xml_errors.
1505 Allow (but warn) unknown XML attributes in MARCXML parsing.
1507 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1509 The UTF-8 to MARC-8 conversion now uses a different set of characters
1510 for Greek symbols. Bug #2120.
1512 --- 3.0.26 2008/02/21
1514 Added yaz_daemon (daemon.h).
1516 Fixed bug #2068: pkg-config trouble
1518 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1520 --- 3.0.24 2008/01/28
1522 Document --with-xml2 option.
1524 Added OPAC XML XSD (etc/opacxml.xsd).
1526 Allow glob mask for name attribute in retrieval element for the
1527 generic frontend server's retrieval facility.
1529 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1530 except POLLIN/POLLOUT.
1532 Fixed error handling in cs_listen. Bug #2037.
1534 --- 3.0.22 2008/01/20
1536 Fixed version in yaz/yaz-version.h.
1538 Fixed bug #2027: Crash when closing connection.
1540 Changed configure so that ICU support is only enabled if only ICU
1541 and Libxml2 is available (because the ICU chain is XML based).
1543 --- 3.0.20 2008/01/15
1545 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1546 is built. Only this DLL depends on the ICU runtime.
1548 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1549 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1551 Changed license of CCL module to 'Revised BSD'. After consultation with
1552 remaining members of the original EUROPAGATE consortium, we are re-issuing
1553 the CCL module without a separate license. The software was developed by
1554 Index Data as part of a research project. The special license was included
1555 to help feed usage information back to the project consortium to support
1556 project evaluation. At this time, the project consortium has long-since
1557 disbanded, and the majority of the original principals have retired. At the
1558 same time, we have significantly modified the software during the following
1559 years, to the point where very practically no original code remains. To
1560 simplify re-use of the software, we have contacted those members of the
1561 consortium who could be reached, and agreed to re-issue the module as a
1562 proper part of the YAZ package.
1564 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1566 CQL closer to being version 1.2 compliant. CQL also allows free-form
1567 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1570 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1571 bug could make Extended services handling crash in the ZOOM layer. This
1572 bug was only present in YAZ 3.0.18.
1574 --- 3.0.18 2007/12/19
1576 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1579 yaz-marcdump reads and writes collection wrapped records.
1581 Handle OPAC for record conversion module.
1583 Fixes for ICU wrapper.
1585 Allow ICU libs to be controlled with --with-icu .
1587 --- 3.0.16 2007/11/12
1589 Added yaz_poll which is a wrapper for select/poll. When poll is available
1590 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1591 sockets to be in use.
1593 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1594 functionality through an XML based configuration (ICU chain). This system
1595 is useful for search facilities such as Pazpar2 and Zebra that needs to
1596 perform tokenization of indexed material. The ICU code in a separate
1597 library libyaz3_icu.a.
1599 Added HTTP tunnel facility for COMSTACK, bug #1752.
1600 This is a facility that allows a Web proxy, such as squid, to tunnel
1601 Z39.50 traffic. This facility is "transparent" to must applications
1602 using YAZ. It's enabled by using pseudo transport connect: followed by
1603 the proxy address, followed by command, then follwed by he regular
1604 "virtual" addresss. For example,
1605 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1607 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1609 --- 3.0.14 2007/09/21
1611 Fixed bad memory reference in ZOOM_record - cuased by member not being
1612 initialized. This was a problem only in YAZ 3.0.12.
1614 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1615 fields were not removed.
1617 Changed the way C code is generated from codetables.xml. Made a MARC-8
1618 conversion trie for each characterSet section rather than codeTable.
1619 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1620 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1622 --- 3.0.12 2007/09/12
1624 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1625 from ZOOM_record_error).
1627 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1629 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1631 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1633 Better SRW-to-Bib-1 diagnostic mapping.
1635 ZOOM C and yaz-client announces SRU version 1.2 by default.
1637 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1640 Fixed in yaz_sru_decode to allow other version than 1.1.
1642 --- 3.0.10 2007/08/22
1644 Added support for SRU scan for ZOOM.
1646 Added support for the use of the older versions or Extended Service
1647 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1648 set to the version , 1=first, 2=second, 3=third. The third version is
1649 what ZOOM C has used so far. And that, obviously, is the default.
1651 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1652 therefore in Zebra and in SimpleServer-based applications). The new
1653 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1654 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1655 which is passed into the back-end search callback function.
1657 Added support for HTTP Basic authentication in clients: the SRU/W
1658 codec encodes the username/password elements of the PDU structure
1659 appropriately, and these may be set using the "user" and "password"
1660 options in ZOOM-C applications (the same options that are used for
1661 Z39.50 authentication).
1663 --- 3.0.8 2007/06/25
1665 Fixed bug #1208: SSL appears to be broken in ZOOM.
1667 Fixed bug #1206: Libxml2 include path weirdness.
1669 Added oid_name_to_dotstring.
1671 Allow elementSetName to be specified for ZOOM C record update.
1673 Allow waitAction to be specified for ZOOM C based for Extended Services.
1675 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1676 syntax OID. Bug introduced in YAZ 3 series.
1678 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1680 --- 3.0.6 2007/06/06
1682 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1683 directory. yaz-client now reads commands from file given by option -f
1684 if specified; then tries to read .yazclientrc in current directory.
1685 Failing that, it reads .yazclientrc from user's home directory.
1687 Added support for correlationInfo Note and ID for Record Update via
1690 Added yaz-client command querycharset which specifies character set for
1691 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1692 (termListAndStartPoint).
1694 Charset ISO5428:1984 is an alias for ISO5428-1984.
1696 Implemented a way to perform scan in a result set using Z39.50. This
1697 is achieved by attaching the result set name in the characterInfo
1698 (type InternationalString) of OtherInformation in the Scan Request PDU.
1699 The result set is identified in the otherinformation by the new OID:
1700 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1701 This allows for scan in result set and faceted search . Zebra did some
1702 of this in the APT term using attribute type 8 and value being result
1703 set. Using the OtherInformation approach for this is cleaner and easier
1704 to work with in proxies and the like. This facility can be used in
1705 yaz-client using new command setscan which takes a result set as first
1706 argument, start position (APT) as second.
1708 Changed decoding of SRU XML packed records to deal with servers that
1709 have recordData with XML data with multiple root nodes. Also make
1710 comparison for recordPacking case insensitive. Again, one server
1711 returns "XML" where others return "xml".
1713 For SRU responses allow Content-Type application/xml as well as text/xml.
1715 --- 3.0.4 2007/05/21
1717 Fixed bug in character set conversion of BER strings. Bug introduced
1720 --- 3.0.2 2007/05/08
1722 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1724 For OID class, use oid_class consistently.
1726 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1729 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1730 character set for bibliographic information interchange". By Giannis Kosmas.
1732 Added documentation on new OID API.
1734 --- 3.0.0 2007/05/02
1736 Changes to generic frontend server interface: added new member
1737 'query_charset' for bend_initrequest structure. A backend init handler
1738 should set this member to its native character set for query terms.
1739 When defined, the frontend server logic will announce this character set
1740 to a client if the negotiationModel bit is set by the client. All server
1741 implementors are encouraged to specify this. If a backend server does not
1742 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1744 Added CCL utility to remove terms (stop words) from resulting RPN
1745 tree. This is handled by functions with prefix ccl_stop_words_ .
1747 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1748 terms in RPN queries.
1750 Clean-up the CCL API. Moved some internal structures from ccl.h to
1751 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1752 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1753 This is replaced by ccl_parser_find_str which takes a string instead.
1755 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1756 libyaz.la is the core of YAZ except the generic frontend server and
1757 does not depend on POSIX threads anymore. libyaz_server.la is the
1758 generic frontend server facilities and uses POSIX thread functionality
1759 if available. The libyaz.la no longer depends on POSIX threads because
1760 the number of global structures is limited. NMEM no longer re-uses blocks
1761 between threads ; it simply free's memory immediately but allocates in
1762 "large" chunks as usual. We don't expect any performance penalties
1763 because of this. The yaz_log system is still using a global log_level so
1764 caution must be taken when modifying it with yaz_log_init_.. +
1765 yaz_log_mask_str. This, however, should not cause any trouble because
1766 these functions are called during initialization of application code
1767 anyway. `yaz-config --libs server` returns libs for server applications;
1768 `yaz-config --libs` returns libs for non-server applications.
1770 New OID database - with public definitions in oid_db.h. Removed old OID
1771 database including the head oid.h and definitions such as enum oid_value
1772 and struct oident. The new OID database uses the same string names as
1773 before but the 'protocol' is gone. There are now only two representations
1774 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1775 converts from string to OID; functions with prefix yaz_oid_to_string
1776 converts the other way.
1778 Change to emit_term() in CQL-to-PQF query translation: when a term has
1779 the /regexp relation modifier, do not process it for leading and
1780 trailing "^" and "*", which have quite different meanings in regular
1783 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1784 write handlers no longer carries a 'last' parameter. This will make
1785 yaz_iconv flush "less" characters. A flush is performed by call to
1786 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1788 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1789 removed, because function yaz_query_to_wrbuf does the same.
1791 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1792 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1794 Deprecated MARC utility functions removed.
1796 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1799 Branch split: YAZ_2_1_55_branch
1801 --- 2.1.54 2007/03/16
1803 Fix to ZOOM-C so that transparent reconnection is properly handled on
1804 connections that are in asynchronous mode.
1806 Fixed compilation on OpenBSD 4.0.
1808 Large strings in GRS-1 records are now properly displayed in yaz-client.
1810 Added character conversion support for "advancegreek"; based on patch from
1813 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1814 sequence is met. Before the error was not set so it would be unknown.
1816 Adjust yaz-marcdump MARC reader so that it skips until record separator
1819 --- 2.1.52 2007/03/07
1821 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1822 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1823 fd_set structure used as a bitmask for the FDs to be selected on.
1825 Using ACX_PTHREAD macro to check for POSIX threads.
1827 Fixed have-vsnprintf check.
1829 --- 2.1.50 2007/02/23
1831 Fixes for configure on BSD. Bug #900.
1833 Added snprintf/vsnprintf wrappers for systems that don't have
1834 limits (heavens forbid).
1836 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1837 created before all previous tasks were completed and removed from the
1838 task queue, the new task could be removed by a mistake.
1840 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1842 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1844 Fixed bug #832: Problem with MARC/charset in yaz-client.
1846 Fixed bug #668: save command line history for yaz-client.
1848 Fixed bug #830: pkg-config support.
1850 --- 2.1.48 2007/01/23
1852 Extended ZOOM result set options with two options that may be read by
1853 a client: resultSetStatus and presentStatus with values as specified for
1855 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1857 Fixed bug #827: Using SSL fails on Debian etch.
1859 Fixed bug #826: Weird looking chars for set of MARC records.
1861 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1862 that is treated as an ItemOrder with itemRequest being an XML document
1863 external. The value of "doc" is the content.
1865 Extended the GFS search facility. New member of bend_search_rr
1866 'estimated_hit_count' signals that hits is known to be an estmate
1867 (higher or lower than real hit count). New member 'partial_resultset'
1868 signals that the search was partial (hit count is lower or equal than
1869 real hit count). For Z39.50, the information is stored in resultSetStatus
1870 member of SearchResponse APDU. For SRU, the information is signalled
1871 via SRU diagnostic 59: "Result set created with valid partial results
1874 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1876 --- 2.1.46 2007/01/13
1878 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1880 Added ZOOM_connection_peek_event.
1882 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1883 the following new functions:
1884 ZOOM_event_nonblock, ZOOM_connection_process,
1885 ZOOM_connection_get_{socket,mask,timeout},
1886 ZOOM_connection_fire_event_{timeout,socket}.
1887 The existing blocking event handler, ZOOM_event, is a wrapper for the
1888 + blocking ZOOM_event_sys_{poll,select}.
1890 Implemented function ccl_xml_config which parses XML version of CCL
1891 configuration (bug #798).
1893 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1895 Added timings utility (yaz/timing.h)
1897 --- 2.1.44 2007/01/03
1899 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1902 Fixed bug #779: Rotation of apdu.log fails.
1904 Fixed for character set conversions:
1905 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1906 Honor G1 set in MARC-8 decoding.
1908 --- 2.1.42 2006/12/17
1910 Fixed bug #775: char conversion does not handle Alternative UTF-8
1913 Implemented function yaz_marc_read_line which parses MARC line format
1914 records. There is a wealth of formats out there. So far, this function
1915 reads line records produced by yaz_marc_write_line.
1917 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1918 more generic and easier to remember(!) options: -i format and -o format
1919 which specifies input format and output format respectively - where
1920 format is one of "marc", "marcxml", "line", "marcxchange".
1922 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1923 does not print anything except warnings for records.
1925 For yaz-marcdump, added support for MARC split into files (-s) with a given
1928 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1929 spec, at http://www.loc.gov/standards/sru/record-update/
1930 This has changed the binary layout of the following structs:
1931 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1932 bend_update_rr . Patch by Ko van der Sloot.
1934 Added GFS utility function bend_assoc_is_alive which returns 1 if
1935 association is still alive (client is connected); 0 otherwise (client
1936 closed connection). This allows busy servers to stop working for
1939 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1940 been a separate piece of software. This version of ziffy has been modified
1941 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1943 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1945 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1946 Client code may now interrogate options such as "init_opt_sort" to
1947 find out whether the server claims to support various options.
1949 --- 2.1.40 2006/11/27
1951 Added utilities yaz_{set,get}_esn to set/get element set name from
1954 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1955 of YAZ and has been so since YAZ 2.1.10.
1957 Implemented ZOOM_record_error which returns error information for
1958 record (surrogate diagnostic).
1960 --- 2.1.38 2006/10/31
1962 Updates for SRU Update by Ko van der Sloot:
1963 1. Changed name from "operation" to "action"
1964 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1965 versions in the code, marked as 'backward compatible'.
1966 3. Added diagnostics for SRU Update.
1968 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1970 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1972 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1974 For GFS, fixed problem with SRU diagnostic 'First record position out of
1975 range' being issued for 0 hits.
1977 zoomtst10 part of Windows Build.
1979 --- 2.1.36 2006/10/13
1981 Implemented yaz_filepath_comp which splits a path into file path
1982 components (required by Zebra 2.0.3+).
1984 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1985 BSD inspired license until now so this should not have any real impact on
1986 anybody. See http://www.opensource.org/licenses/bsd-license.php
1988 Fixed bug #687: Missing log lines.
1990 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1993 Fixed bug #689: SRU diagnostics to be added.
1995 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1996 whether a connection is idle (no more work do do).
1998 --- 2.1.34 2006/10/04
2000 Change type of optval from long to int for invocation of setsockopt with
2001 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2003 Added support for specifying the max log file size for the Generic
2004 Frontend Server. The size is given with option -r.
2006 --- 2.1.32 2006/09/21
2008 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2010 --- 2.1.30 2006/09/17
2012 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2015 Fixed bug in Generic Frontend Server that could cause a server to stop
2016 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2018 For the generic frontend server, the maximum record size is used as maximum
2019 size of incoming packages (SRU + Z39.50). The value until was previously
2020 only used in Z39.50 Init negotiation and, later, in a session controlled
2021 sizes of records returned. This is controlled using -k option. It can be
2022 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2024 --- 2.1.28 2006/09/04
2026 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2029 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2031 New option for yaz-marcdump -lpos=value which allows setting a portion
2032 of MARC header to a certain value.
2034 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2036 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2037 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2039 --- 2.1.26 2006/08/15
2041 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2044 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2046 --- 2.1.24 2006/08/08
2048 Fixed MARC ISO2709 encoding routines to deal with character set
2051 Minor changes to GFS logging. Database included in search request log
2054 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2055 cached/multiple records.
2057 Shared libraries are built by default on Unix+configure.
2059 Changed cql2pqf transformation to use a different evaluation order. The
2060 new order is: always, relation, structure, position, truncation, index
2061 and relationModifier. Old order was: always, relation, relationModifier,
2062 structure, index, position, truncation. Note that the the latter ones
2063 override former ones for identical attributes.. The new scheme means that
2064 it is possible to override any existing attribute with a relationModifier.
2065 And also that it is possible to override everything for the index rule
2066 (except the ones listed in relationModifier). No order is perfect but this
2067 one, we believe, covers more real cases.. The "always" should have been
2068 called "default", since the attributes there can be overridden with all
2071 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2072 compilation phase, but also for yaz-config --cflags output. This allows
2073 us to have public headers with Libxml2 stuff in them . It should also,
2074 eventually, make Libxml2 checks redundant in packages using YAZ, such
2077 --- 2.1.22 2006/06/15
2079 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2080 stored in uri, message and details.. Previously diagnostics were stored
2081 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2082 compatibility.. but he's probably the only one affected, so.
2084 Added support for CCL, compiled on the client side, in ZOOM-C. This
2085 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2086 input; the resulting query objects can be used for for searching with
2087 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2089 YAZ' configure searches for OpenSSL by default.
2091 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2092 SL_CTX_use_certificate_file. See
2093 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2094 for more info. Thanks to Ko van der Sloot.
2096 --- 2.1.20 2006/06/02
2098 Bug #600: SRU GET, POST support for yaz-client. Introduced
2099 command 'sru' which selects method SOAP/GET/POST.
2101 Allow missingValueAction to be specified for the sortspec string -
2102 function yaz_sort_spec. By default, the missing value action is null.
2103 Use ! to specify "abort". Use = followed by stringvalue to specify default
2106 Ensured that Present-handler (if defined) is called in GFS before any call to
2107 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2108 searchRetrieve requests.
2110 Documentation for YAZ is now based on the Docbook XML/XSLT using
2111 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2112 is no longer depending on jade/openjade or docbook-to-man scripts.
2113 PDF is no longer part of the distribution - but can optionally be
2114 made using DSSSL/jadetex or FOP.
2116 Added retrieval handling support in Generic Frontend Server to support
2117 conversion between MARC/XML as well as XSLTtransforms. See
2118 etc/yazgfs.xml for an example.
2120 Added Authentication support to Generic Frontend Server in SRU
2121 mode. Authentication using HTTP Basic is supported, as is the use
2122 of 'x-username' and 'x-password' parameters in the request itself.
2124 Added support for a new character set MARC8s identical to MARC8 except
2125 that it converts combined characters to single Unicode characters in the
2126 Latin-1 range (when possible).
2128 --- 2.1.18 2006/04/24
2130 ASN.1 compiler 0.4: generates brief Doxygen file header for
2131 generated .h/.c files.
2133 Utility yaz_iconv now supports conversion to MARC-8.
2135 New facilities for the MARC module. The reading - and writing of
2136 content are separate methods for the yaz_marc_t handle. The following
2137 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2138 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2139 format). Write functions have prefix yaz_marc_write_.. The existing
2140 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2141 available. Removed support for OAI-MARC and simplexml (not the
2142 simplexml from PHP5).
2144 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2145 to be returned for this connection.
2147 --- 2.1.16 2006/03/31
2149 Allow multiple languages and charsets to be specified with
2150 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2151 negcharset iso-8859-1,utf-8
2153 Translation of proximity nodes from CQL into PQF now works.
2155 Moved to automake 1.8, 1.9.
2157 Added function yaz_log_set_handler which allows a log handler to be
2158 installed. This handler will be called for all log messages. Output
2159 to file is also produced; but that can be disabled by passing NULL
2160 fname to yaz_log_init_file.
2162 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2164 For SRW (including GFS), accept application/soap+xml as content-type
2167 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2168 produces NO stylesheet reference even if a default stylesheet is specified
2171 --- 2.1.14 2006/03/14
2173 Updated Windows package to include yazd.dll + yazd.lib for the
2174 Development component.
2176 If the environment variable YAZ_LOG is set, then it is used as a
2177 string indicating the default level of logging to use if not
2178 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2179 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2180 used as before. So, for example, to omit warnings from YAZ logging,
2181 export YAZ_LOG=-warn
2183 cql_transform() now map structure and other attributes before indexes,
2184 so that index-specific structures and other attributes can override
2185 defaults. So now a combination of mapping specifications such as:
2187 index.dc.date = 1=date-modified 4=5
2188 does the right thing.
2190 cql_transform() now also respects the "always" mapping specification,
2191 which establishes an initial set of attributes to be used for all
2192 terms except where overridden by more specific attributes associated
2193 with the index, relation or modifier.
2195 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2196 which mode to use; one of "post", "get" or "soap" (SRW, default).
2198 Fixes for yaz_iconv routines: changed trie-based character set conversions
2199 to use only non-negative values for bit fields due to Sun's C compiler not
2200 supporting negative values.
2202 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2203 sequences where not read correctly. Fix by Rustam Usmanov.
2205 Updated win/makefile to use options, settings which makes things
2206 compile with VS C 2005.
2208 --- 2.1.12 2006/02/01
2210 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2212 In ZOOM socket code, use select instead of poll on MacOSX.
2214 ZOOM-C now support client-side compilation of CQL into RPN that is
2215 sent to the server, enabling CQL to be used against all Z39.50
2216 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2217 ZOOM_query object, and submit it using ZOOM_connection_search().
2218 The CQL-to-RPN translation uses a configuration file, the name of
2219 which must be specified in the Connection's "cqlfile" option.
2221 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2222 function, which takes as its start-term parameter a ZOOM_query object
2223 (which may have had either CQL or RPN set into it).
2226 --- 2.1.10 2005/11/29
2228 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2229 GFS to support this as well. Backend handler, bend_srw_update, does the
2230 update work. Code contributed by Ko van der Sloot.
2232 Allow retrieval of Search Result-1 information in ZOOM by the use of
2233 options that are attached to a result set. ZOOM documentation updated
2236 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2237 UTF-8 conversion. Patch by Raj Patel.
2239 Added option -m to GFS to control formatting of timestamps in log file.
2241 Added 'exit' as synonym for 'quit' in yaz-client
2243 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2244 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2245 for the new members. Patch by Ko van der Sloot.
2247 Added support for SRU POST. It is supported for content-type
2248 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2250 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2251 Instead make the library libyaz.la multi-threaded. Threading as a whole
2252 can still be disabled by configure option --disable-threads. Previosly,
2253 with older GLIBCs there were problems with MT libs under Apache. This
2254 has now been fixed a long time ago.
2256 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2259 CQL module modified to be case insensitive for relations/indexes/operations.
2261 Fixed bug in CQL transform code: incorrect value relationModifieder
2264 Added 'show all' command for yaz-client which retrieves all results
2267 Added new yaz-client, xmles, which takes a (private) OID and
2268 a document to be sent as an extended service request.
2270 Describe new yaz-client commands wait_response and set_auto_wait.
2272 Increase TCP/IP listener backlog from 3 (which I am guessing was
2273 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2274 that the socket will queue as many incoming connections as it's able
2275 to handle ongoing connections. In other words, it will never now
2276 refuse a connection that it would be able to handle merely because
2277 it's not got around to accepting() enough of the pending connections
2278 yet. This is the behaviour anyway under Linux, where the listen()
2279 argument is ignored; but not under BSD and on systems such as
2280 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2281 YAZ-based servers should now be uniform across operating systems in
2284 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2285 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2286 This allows yaz-marcdump to read large MARC batches (>2 GB).
2288 Modified all YAZ source files - except the source which is auto-generated
2289 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2292 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2293 corresponding to the existing *_setl() function. These allow option
2294 values containing arbitrary valuues.
2296 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2297 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2298 except that it returns an indicator of whether or not the sort
2299 criterion was accepted (0 for OK, -1 for invalid).
2301 --- 2.1.8 2005/06/07
2303 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2304 MARC output rather than returning "new" buffer.
2306 yaz-client warns about unknown init options.
2308 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2310 --- 2.1.6 2005/05/24
2312 Added support for SRW sort in Generic Frontend Server. Patch
2313 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2314 sortKeys - or NULL if none is provided.
2316 Fixed bug #307: It was impossible to specify indefinite/no timeout
2317 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2320 Added support for multiple languages and charsets to be specified in
2321 ZOOM. Each charset/language is separated by a blank. If negotiation is
2322 in effect in init-response, Option
2323 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2324 Code based on patch by Vasiliy Osadchuk.
2326 Fixed bug #306: infinite recursion that occurred when calling
2327 yaz_log_level_init as the first call (before other log level or
2330 Fixed bug in scan handling in front end server: if preferred-Position-In-
2331 Response was non-present, a NULL pointer referece was performed.
2333 --- 2.1.4 2005/04/26
2335 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2336 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2337 now defined for all those error codes. So instead of putting 109 in
2338 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2339 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2341 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2344 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2346 Program yaz-client now exits and produces an error message if multiple
2347 Z39.50 servers are specified on the command line (none or one allowed
2350 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2353 --- 2.1.2 2005/03/16
2355 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2357 Fixed bug #272: Preserve spacing for CCL terms.
2359 --- 2.1.0 2005/03/14
2361 Added support for virtual hosts and multiple backend servers for
2362 the YAZ frontend server. The configution is XML based and
2363 support specificition of CQL to RPN mappings and explain information.
2364 See section "Virtual Hosts" in the YAZ manual.
2366 Extended OPAC display utility. OPAC display utility renders
2367 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2368 to supplement yaz_marc_decode_wrbuf.
2370 Fixed a bug in MARC decoder that could caused it to crash for some
2371 invalid MARC records. More diagnostics and warnings where added in
2372 XML output (warnings, etc are stored in comments).
2374 --- 2.0.34 2005/02/08
2376 Fixes for UNIX domain sockets. Bug #261.
2378 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2380 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2381 Added yaz_marc_subfield_str which defines subfield lead string which is
2382 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2383 yaz_marc_endline_str which defines end of fields string used in
2384 YAZ_MARC_LINE format. Default string is newline.
2386 Experimental support for MarcXChange. This format can be produced
2387 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2388 http://www.bs.dk/standards/MarcXchange.xsd
2390 Added yaz-client commands scansize that sets maximum number of
2391 entries to be returned by scan.
2393 --- 2.0.32 2005/01/11
2395 Added support for SRW scan in yaz-client and Generic Frontend Server.
2397 * Added whereInList member to SRW Scan Term.
2399 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2401 Fixed NMEM system to return aligned blocks on the smallest boundaries
2402 that are suitably aligned for all possible types on the particular
2403 architecture YAZ is being built for.
2405 --- 2.0.30 2005/01/04
2407 Fixed numerious warnings that was issued with newer versions of GCC.
2409 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2410 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2413 Make YAZ Generic Frontend Server slightly faster.
2415 Enhance (and reduce) logging for Generic Frontend Server.
2417 Revert YAZ log system so that it flushes every write operation
2418 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2420 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2421 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2422 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2423 will effectively disable old definitions.
2425 --- 2.0.28 2004/11/09
2427 Added yaz_log_time_format which specifies log format using
2430 Added yaz_log_module_level which returns mask for a module. Value
2431 is non-zero mask a if module is enabled; zero if disabled.
2433 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2434 in include/yaz/cql.h.
2436 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2438 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2440 Fixed bug #172: RPM builds does not enable SSL.
2442 Doxyfile.in part of dist. Doxyfile generated by configure.
2444 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2445 are given and the corresponding component does not exist.
2447 Extend CCL documentation in YAZ reference. Describe r=r.
2449 --- 2.0.26 2004/10/01
2451 Fixed MARC->MARCXML conversion to properly deal with
2452 fields, subfields, indicators having non-ASCII characters.
2454 Fixed MARC->MARCXML conversion so that ASCII control characters
2455 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2458 Added YAZ GFS support for conversion from Z39.50 surrogate
2459 diagnostics to SRW surrogate diagnostics.
2461 Bug fix: YAZ GFS did not return schema in explainResponse.
2463 --- 2.0.25 2004/09/30
2465 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2466 now converts recordSchema to elementSetName as well as schema URI.
2468 Fixed bug in COMSTACK that prevented HTTP request packages from being
2471 --- 2.0.24 2004/09/29
2473 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2474 does not require white-space before and after the dash in a range, e.g.
2475 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2478 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2479 due to new GCC removing "redundant" code.
2481 Added yaz-client commands scanpos and scanstep that sets preferred
2482 position and step-size for scan.
2484 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2486 Added CCL utility ccl_qual_buf which parses one or more CCL
2487 spec lines in a buffer.
2489 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2490 of name and value - ignoring empty lines and comments.
2492 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2494 Added odr_get_element_path which returns current element path for an
2495 ODR handle. This utility is useful in error handling or user-defined
2498 Added ODR_PRINT utility odr_set_stream which is is a more generic
2499 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2500 to a write function and pointer to close function. The close function - if
2501 non-NULL - will be called during odr_destroy.
2503 Fixed bug in CCL parser where truncation char was not removed from
2504 right side when truncation=both was in effect.
2506 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2509 --- 2.0.23 2004/08/11
2511 Fix buffer overrun in CQL parser when dealing with proximity (%).
2513 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2514 to UTF-8/UCS conversion is now only based on codetables.xml.
2516 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2518 --- 2.0.22 2004/08/06
2520 Add support for more "commit changes" in ZOOM (uses Extended Services).
2522 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2525 Yet another small fix for configure of SSL.
2527 --- 2.0.21 2004/05/14
2529 Fix SSL libs for configure when --with-openssl=DIR is given.
2531 --- 2.0.20 2004/05/10
2533 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2535 SSL comstack now uses yaz.pem certificate file on server side
2536 by default. Certificate filename can be configured by calling
2537 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2539 Fix bug regarding multiple calls to ZOOM_connection_connect.
2541 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2543 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2544 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2546 ZOOM now allows inspection of X509 peer certificate for verification.
2547 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2549 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2550 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2551 as "modular" but it simplifies things.
2553 Added cs_get_peer_certificate to that returns peer X509 PEM.
2555 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2556 NULL if SSL is unavailable.
2558 Documentation about MARC decoding tools.
2560 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2562 --- 2.0.19 2004/03/30
2564 Rename CHANGELOG to NEWS to follow GNU style packing.
2566 Fix bug with missing initialization of member in init_diagnostics.
2567 This bug affects threaded version of GFS server.
2569 --- 2.0.18 2004/03/20
2571 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2574 Ensure zlib.dll is packed with Windows install.
2576 --- 2.0.17 2004/03/17
2578 Fix encoding of xsd:string to use text instead of CDATA.
2580 Fix endless loop in CQL parser with unbalanced ".
2582 Use a more compact way to store MARC-8 conversion tables.
2584 --- 2.0.16 2004/03/16 Debian only
2586 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2589 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2594 --- 2.0.15 2004/03/01
2596 Another fix for decoding of XML packed records.
2598 --- 2.0.14 2004/02/25
2600 Fixes for Chunked encoding. White space not ignored after length spec.
2602 Update NS and use default NS for SRW diagnostic elements.
2604 --- 2.0.13 2004/02/23
2606 Implement ZOOM_resultset_cache_reset which resets record cache.
2608 Implement ZOOM_resultset_sort which sorts a result set.
2610 Implement chunked HTTP transfer.
2612 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2614 --- 2.0.12 2004/02/16
2616 Added member 'schema' to bend_explain_rr structure so that backend
2617 can specify explain record identifier. Defaults to Zeerex 2.0.
2619 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2621 --- 2.0.11 2004/02/16
2623 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2626 Added init command for yaz-client which sends "extra" init request.
2628 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2629 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2631 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2633 Make ZOOM error code for "invalid query".
2635 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2637 --- 2.0.10 2004/02/05
2639 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2642 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2644 Added option -p <file> to make Generic Frontend Server to write PID file.
2646 Added option -D to put Generic Frontend Server in background on its own.
2648 Make ZOOM C recognize option "password". If unset, "pass" is used
2649 (for backwards compatibility).
2651 Fixed a bug in Generic Frontend Server that could make it crash if a
2652 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2655 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2656 Must be issued before open, in order to be in effect.
2658 --- 2.0.9-6 2004/01/12 Debian/Windows
2660 Make the SRU server more picky WRT unknown params, etc.
2662 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2664 New YAZ client command, options, that sets Z39.50 options.
2666 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2667 options from a string of tokens (one token for each option bit).
2669 Update SRW diagnostic code messages.
2671 --- 2.0.9-5 2004/01/07 Debian/Windows
2673 Handle user defined stylesheet for SRW/SRU.
2675 --- 2.0.9-4 2004/01/06 Debian/Windows
2677 Fix bug in decoding of Content-Length.
2679 --- 2.0.9-3 2004/01/06 Debian/Windows
2681 Fix a bug with decoding of XML packed records.
2683 --- 2.0.9-2 2004/01/05 Debian only
2685 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2687 Fix bug in SRW/SRU diagnostics decoding.
2689 --- 2.0.9 2004/01/05
2691 Fixed bug in Generic Frontend Server which could drop records exceeding
2692 preferred message size. Reported and fixed by Irina Dijour.
2694 Fixed calculation of package size for structured records in Generic
2695 Frontend Server. Reported and fixed by Irina Dijour.
2697 Fixed namespace for SRW/SRU diagnostics.
2699 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2701 --- 2.0.8 2003/12/22
2703 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2704 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2707 CQL changes to reflect recent changes to the specification:
2708 * Documentation talks about context sets instead of index sets.
2709 * Documentation talks about indexes instead of qualifiers.
2710 * The CQL-to-PQF transformer's configuration file now uses
2711 "index.set.name = <attributes>" instead of the old form
2712 "qualifier.set.name = <attributes>". (Both forms are still
2713 understood but the latter is deprecated.)
2714 * CQL terms with no explicit index specified are now interpreted as
2715 cql.serverChoice instead of srw.serverChoice (which of course
2716 behaves exactly the same.)
2718 --- 2.0.7 2003/12/16
2720 MARC conversion can now generate ISO2709 output in another
2721 character set. yaz-marcdump uses this facility if you invoke it
2724 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2725 functions from there can be used from C++.
2727 --- 2.0.6 2003/12/04
2729 Frontend server now transfers memory from decoded packages to stream
2732 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2733 references to show up.
2735 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2736 the ZOOM Abstract API. The older names for the same options are still
2737 also supported for the benefit of old applications.
2739 ZOOM-C supports "implementationId" and "implementationVersion" options
2740 to go along with "implementationName". These allow the user code to
2741 specify identification strings to be sent to servers.
2742 Add OID for the new ExtLite attribute set.
2744 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2745 as requested/supplid by Ere Maijala <ere@atp.fi>
2747 For generic frontend server, reverse the order of
2748 "toolkit-supplied / application-supplied" strings sent as implementationId,
2749 Name and Version. Also, remove the spaces around the slash. This brings
2750 the GFS in line with the behaviour of ZOOM-C on the client side.
2752 Add function ZOOM_scanset_display_term.
2754 yaz-client shows scan displayTerm if present.
2756 Utility yaz-iconv is now installed by default along with the man page
2759 Extend configure check for OpenSSL to use pkg-config where available (such
2762 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2763 server to specify uid/gid/mask for socket using the format
2764 unix:[user=uid,][group=gid,][umask=mask,]file=path
2765 If file= is omitted the existing format is assumed, e.g.
2767 in which case the mask is 0666 (rw for everybody).
2769 Major restructure of YAZ source. All source in libyaz is in src directory.
2770 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2771 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2773 Added man page for utility yaz-marcdump (used to be called marcdump).
2774 yaz-marcdump is installed by 'make install'.
2776 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2777 of incoming package failed.
2779 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2781 Change prototype of odr_perror: add const to message string.
2783 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2785 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2786 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2787 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2788 DNS lookup. There should not be any compatibility problems with this
2789 assuming that blocking=1 or 0 is used.
2791 Fix bad reference in UNIX comstack in function cs_addrstr.
2793 Fix for compilation on AIX.
2795 The generic front-end server (server/seshigh.c) now supports returning
2796 Init diagnostics to the client in User-information-field, in
2797 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2800 --- 2.0.4 2003/09/04
2802 Allow any CQL relation (not just all,any,exact,scr).
2804 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2805 that features the same UI.
2807 Implemented command update0 in YAZ client which is equivalent to
2808 update but uses old of Ext Update ASN.1.
2810 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2811 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2812 Previously no OID was used for this info.
2814 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2815 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2816 returns 'malformed search term' otherwise.
2818 SortResponse member resultCount now set to NULL in sort handler of
2821 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2824 Add three new utility functions for translating OIDs between various
2825 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2826 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2827 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2828 char *oid_to_dotstring(const int *oid, char *oidbuf);
2829 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2831 Reverted modifications for ES Update definition for z_IU0Update
2832 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2833 is back to YAZ 2.0.2.
2835 String value attributes for CCL parser.
2837 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2838 which their FirstSearch server returns in Init responses, sometimes
2839 carrying useful diagnostic information when Init fails. This has the
2840 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2841 "z39.50/oclcui.asn", where its definition is somewhat different from
2842 what OCLC document on their web-site, as required to interoperate with
2845 Support for anonymous authentication in yaz-client. Use the command
2848 * Fix the OID of the Index Data-local "admin" Extended Service from
2849 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2850 the 1000, which indicates a locally-defined OID, was a mistake.
2852 --- 2.0.3 2003/06/20
2854 Fix CCL directive @case handling so that it affects string match for
2855 both CCL keywords and qualifiers.
2857 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2858 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2859 Decoder has been updated with ASN.1 changes as listed in
2860 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2861 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2862 z_IUUpdate, remains unchanged.
2864 ZOOM_record_get may now return a record in a specific character set.
2865 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2866 "from" is the character set of record as returned by target. "to" is
2867 the character set to be returned. If omitted, "to" is UTF-8.
2869 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2871 New ODR utility, odr_getelement, which returns name of element for
2872 which encoding/decoding failed.
2874 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2875 in cases where a required element was omitted.
2877 Bug fix: some MARC8 sequences were not converted.
2879 New ZOOM option "step" which specifies number of records to be
2880 retrieved in one chunk. Used in conjunction with "start" and "count".
2882 SRW support for yaz-client. Use scheme http: to use it, e.g.
2885 yaz-client no longer does (un)intelligent character set conversions
2886 by default. Can be enabled with charset and marc_charset commands.
2888 xmalloc trace fix for 64-bit systems such as DEC alpha.
2890 Solaris 2.6 compile fix.
2892 New function, cql_strerror() translates SRW error codes, as returned
2893 by cql_transform_error(), into human-readable English strings. Used
2894 in yaz-client diagnostics when appropriate.
2896 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2897 converts it into a type-1 query which is sent to the server. This
2898 makes CQL available for use with all Z-servers, as opposed to the tiny
2899 minority that can handle CQL queries themselves.
2901 --- 2.0.2 2003/04/28
2903 New Debian package layout similar to the Redhat Package layout.
2905 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2906 and search result respectively.
2908 --- 2.0.1 2003/04/25
2910 Redhat package is now several packages: libyaz (runtime libraries),
2911 libyaz-devel (development and documentation, and yaz (utility programs).
2912 Package spec file by Morten Bogeskov.
2914 New member 'schema' in struct bend_fetch_rr which the name of requested
2915 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2916 handler MAY set this to reflect the schema of the returned record.
2918 New member 'display_term' in struct scan_entry. GFS now sets member entries
2919 and allocates scan entries to be filled by user scan handler. In previous
2920 version, entries member was allocated by the scan handler. That still works,
2921 but the GFS will ignore member display_term - assuming it was NOT set by
2922 the handler. The fact that the GFS now allocates the entries both allows
2923 for new members and makes a scan handler easier to write.
2925 Fix CQL lex buffer overflow.
2927 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2928 SRU default recordPacking is string.
2930 SRU protocol support for frontend server.
2932 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2934 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2936 Added scan for the ZOOM shell (zoomsh).
2940 * String Identifers for Schemas (Amendment 5).
2941 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2942 Old definition for schema
2943 Odr_oid *schema; /* OPT */
2948 Z_InternationalString *uri;
2949 #define Z_Schema_oid 1
2950 #define Z_Schema_uri 2
2953 * resultCount parameter to Sort Response (Amendment 1).
2954 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2956 Support for SRW 1.0 over HTTP. This is an optional feature and
2957 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2960 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2961 on the same port. SRW SearchRetrieveRequests are mapped
2962 to bend_init,bend_search,bend_fetch,bend_close.
2964 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2966 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2967 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2969 ZOOM connections are SRW based if schem http is used for hostname
2970 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2971 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2973 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2974 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2975 distance=n, order=true/false, relation=le, prox unit=word. If
2976 n is omitted, distance 1 is used.
2978 Fixed problem with C compiler include path in wrong order.
2980 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2981 on Solaris. Patch from Ko van der Sloot.
2983 New MARC decode API. All new functions operate on a yaz_marc_t
2984 handle. The most important new functions are: yaz_marc_create,
2985 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2986 decode and destroy respectively. Decoder can produce formats
2987 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2988 include/yaz/marcdisp.h.
2990 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2991 to UTF-8, UCS-32, wchar_t or Latin-1.
2993 * Prototypes for yaz_iconv_-functions moved to separate header
2994 include/yaz/yaz-iconv.h.
2996 Make a few private functions 'static' in unix.c. This prevents
2997 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2999 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3000 are set when Init Response is received.
3002 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3003 but returns diagnostic set as well.
3005 New function yaz_strerror which is a portable wrapper for
3006 strerror/strerror_r/GetLastMessage.
3008 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3009 is returned for MARC. If type is "oai", then OAI MARC is returned.
3011 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3014 --- 1.9.2 2002/11/26
3016 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3018 Fix bad race conditions on SIGTERM and terminate gracefully in
3021 Move retrieval (data1) module to Zebra since nobody seems to be
3024 Add GRS-1 render for ZOOM using same format as yaz-client.
3026 --- 1.9.1 2002/10/05
3028 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3030 Fix broken ESpec handling in data1 module.
3032 SGML reader parses comments and makes them part of the data1 tree.
3034 Added several type casts so that YAZ compiles as C++ code.
3036 ZOOM didn't handle PDU encoding failures properly.
3038 Added more Bib-1 diagnostics (approved extensions).
3040 GNU configure: better check for iconv.
3042 More portable use of accept, getpeername. Check for socklen_t. Use
3043 int/size_t if socklen_t is not defined.
3047 PQF parser rejects bad queries - including those with extra
3048 characters in them. PQF parser used to silently ignore that.
3049 Cleaner API for PQF added, which allows you to get detailed
3050 error information for bad queries (see yaz/pquery.h).
3052 Fixed bug in ZOOM_record_get for type "database".
3054 Implemented mini iconv library supporting conversions between
3055 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3057 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3059 --- 1.8.9 2002/08/20
3061 Fixed ZOOM C record cache so that preferredRecordSyntax and
3062 elementSetName is used to check for already fetched records.
3064 --- 1.8.8 2002/08/02
3066 Added three members in bend_initrequest structure to facilitate
3067 character set negotiation.
3069 Fixed a bug in frontend server that could cause indefinite
3070 loops under rare conditions.
3072 Revised character set utilities (charneg.h) so that encoding
3073 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3075 For PQF, directive @term <type> sets term type for Scan/Search.
3076 Here <type> is general, string, numeric, null. The term type
3077 is inherited - just like @attr.
3079 New call odr_set_charset that sets character set conversion for
3080 international-strings on a ODR stream. Prototype is:
3081 int odr_set_charset(ODR o, const char *to, const char *from);
3082 The InternationalString is still represented as C string in YAZ
3083 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3084 won't). On the protocol level, you can use any encoding.
3086 Support for UNIX sockets in ZOOM.
3088 Solaris recv sometimes returns errno == ENOENT. It is treated as
3089 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3091 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3092 both client and server. Code by Morten Bogeskov.
3094 --- 1.8.7 2002/05/22
3096 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3097 that they can be used directly from Visual Basic. You must recompile
3098 your windows APP if you're using ZOOM.
3100 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3101 Commands "lang" and "charset" sets language and character set respectively.
3102 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3103 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3105 Attributes from multiple CCL fields may be OR'ed rather than merged
3106 using directive "@field or". Fields are still merged by default -
3107 equivalent to "@field merge".
3109 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3112 Fixed bug in zget for parameter ExtendedServicesResponse.
3116 --- 1.8.6 2002/03/25
3118 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3120 Client displays USR.1:SearchResult-1 (hits per term).
3122 Additional Search Info for search in Generic Frontend Server.
3124 Fixed CCL parsing of "field=s".
3126 WIN32 installer - using the excellent NSIS software from nullsoft.
3128 Fixed CCL parsing of "field = - <number>".
3130 Added function yaz_marc_decode that decodes MARC for line mode
3131 display or XML (similar to that used by JZKit).
3133 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3134 Z39.50. But ISO/ILL was, however.
3136 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3137 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

3140 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3142 --- 1.8.5 2002/02/03
3144 New YAZ client features: Command completion and new commands:
3145 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3146 Code provided by Jacob Poulsen.
3148 New call oid_trav, that visits all registered OIDs via callback.
3150 Function ZOOM_record_get now returns const char pointer rather than
3151 void pointer. It saves a lot of type casts.
3153 For YAZ client, command "auth" now allows you to set authentication
3154 in IdPass style. It is enabled when three tokens are given - order
3155 is user, group and password.
3157 Fix memory leaks in MARC record handling for ZOOM.
3159 New option for YAZ client, -k <kilobytes> that sets
3160 maximum record size. Similar to -k option for generic frontend
3161 server and yaz-ztest.
3163 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3165 Prefix query parser reports "fail" when bad attribute set is given.
3167 Fix in MARC decoder. Proximity logging. Fix for attribute set
3168 in scan handler for server. Patches by Shigeru Ishida.
3170 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3173 Configure option --with-openssl=<dir> now works when a directory is
3174 specified. Patch provided by Morten Bogeskov.
3176 New option for YAZ client, -u <auth>, that sets authentication.
3178 ZOOM fix: error information was sometimes "missing", since error
3179 was cleared/reset too when it shouldn't.
3181 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3183 --- 1.8.4 2002/01/04
3185 Scan for ZOOM API. New object ZOOM_scanset. New functions
3186 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3187 ZOOM_scanset_destroy.
3189 New ZOOM function, ZOOM_connection_last_event, that returns type
3190 of last event (such as "receive data", "send data", "apdu received",
3193 New ZOOM option, schema, that specifies schema for retrieval.
3195 New CCL feature. Qualifiers can be aliases for one or more
3196 other qualifiers (if more than one is given, OR is used).
3198 ZOOM uses named result sets if target supports it.
3200 Two new YAZ client commands: . (dot, which sources a script of YAZ
3201 client commands), and ! (to execute shell command.). Implemented
3204 Working on Debian packages.
3206 --- 1.8.3 2001/11/19
3208 YAZ client enables named result sets only if target supports it.
3210 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3212 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3213 with key="host" to get same result.
3215 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3216 Function Z3950_resultset_record(s) returns references to records
3217 "owned" by resultset. To become owner use Z3950_record_clone.
3219 Function z_ext_record handles Extended Services. Thanks to
3222 --- 1.8.2 2001/11/12
3224 CCL Parser fix: ignore token comma when dealing with and-lists.
3226 Documentation updates for COMSTACK.
3228 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3229 Changed prototype Z3950_records. For some functions, int parameters
3230 were changed to size_t.
3232 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3235 New MARC decode/display function, marc_display_exl, which properly rejects
3236 non-ISO2709 records. YAZ client uses it.
3238 --- 1.8.1 2001/10/29
3240 Fix bug: local attribute set wasn't set correctly in PQF strings.
3244 * Old Z39.50 codecs no longer supported.
3246 Added ZOOM C binding. See http://zoom.z3950.org/
3248 Renamed states for COMSTACKs to avoid confusion with events.
3250 Implemented cs_look and proper cs_rcvconnect.
3252 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3254 Configure detects POSIX threads on OpenBSD.
3256 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3257 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3259 When error is returned from present handler, non-surrogate diagnostic
3260 is returned in present response (and fetch handler is no longer called).
3262 * Minor adjustments to pquery parser (PQF). Token characters may be
3263 escaped by using backslash (C-style).
3265 PQF parser allows string attribute values to be specified. For @attr,
3266 non-numeric characters after the equal-sign are treated as strings
3267 (e.g. @attr 9=title).
3269 CCL trunction character may be defined (@truncation in file)
3271 * function zget_ExtendedServicesRequest sets waitAction to
3272 waitIfPossible (was wait).
3274 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3277 CCL operator names may be set in field definition files (CCL_bibset).
3278 See ccl/bib1 for an example.
3280 Fixes in ASN.1 compiler for C++ compatibility.
3282 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3283 and "op_or" to avoid conflict with C++.
3285 Fixed problem with GNU readline detection on Redhat 7.0.
3287 Added step-size for Scan backend handler.
3289 Fixed bug that made the frontend server crash when no attribute
3290 set was specified for scan.
3292 Front-end server automatically switches to original working directory
3293 when installed as an NT service. Previously -w had to be specified to
3296 Added extended attributes for retrieval module (data1), so that data1
3297 records carry d1_readXML/SGML attributes. d1_read also supports
3298 null-data rules ( <tag/>)
3300 On UNIX when POSIX threads are available, a separate library libyazthread
3301 is created. Programmers should link with that library and the yaz library
3302 when using threads. The reason for the split was that some applications
3303 on Linux, such as Apache, doesn't work well when using shared objects that
3306 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3307 (or any frontend server) in SSL mode by specifying ssl: followed by
3308 address. Only tested on UNIX.
3310 Added feature for CCL module. Virtual structure s=al or s=ol generates
3311 and-list and or-list respectively instead of phrase search.
3315 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3316 log_mask_str. This was done to avoid name conflicts with other libraries
3317 (such as other PHP extensions).
3319 Added raw OID member for preferred record syntax (request_format_raw)
3320 and returned record syntax (output_format_raw) for backend fetch method.
3322 Config file yaz-config now accepts options so that it returns specific
3323 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3325 Shared library support for UNIX using GNU libtool.
3327 * Modified backend interface. Request/Response struct's replaced by
3328 one read/write C struct. For example bend_fetchrequest and
3329 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3330 Every handler - even search has to be registered in bend_init
3331 handler. This means that the YAZ library no longer refers to
3332 external functions and it makes it possible to make the whole
3333 thing a single DLL/SO.
3335 Added Segment handler for backend server.
3337 Added Zmbol/Zebra administrative functions to YAZ client.
3339 Threaded frontend server on UNIX (when POSIX Threads are available).
3340 Starting the server with option -T enables multi-threading.
3344 Added configure option --enable-comp/disable-comp to control use
3345 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3346 located in sub directory asn.
3348 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3349 in ${exec_prefix}/bin along with the other programs yaz-client and
3352 GNU automake used to maintain makefiles.
3354 Added several OID's.
3356 Changed retrieval module so that we can load records with no abstract
3357 syntax defined. Tagpaths in these records are fully composed of string
3360 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3364 On UNIX, the generated makefile now supports a proper 'make install'.
3365 The prefix can be set via GNU configure to set the install location
3366 (default is /usr/local).
3368 * YAZ programs client and ztest were renamed to yaz-client and
3369 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3370 locations, such as /usr/bin,/usr/local/bin,etc.
3372 * YAZ Header files were moved from include to include/yaz. YAZ Header
3373 files are referred to as include <yaz/log.h> rather than <log.h>.
3374 The YAZ include path (-I ..) is therefore the same as before. Programmers
3375 should update their #include statements or use -Ipath/include/yaz
3376 instead. The main motivation for doing this change is that YAZ header files
3377 can be installed in "standard" locations /usr/include,/usr/local/include
3378 without introducing conflicts, since ALL YAZ header files are stored
3379 in subdirectory yaz (under /usr/include for example).
3381 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3382 rather than project/workspace files. We switched because project files
3383 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3386 Changed name of logging function, logf, to yaz_log, to prevent name
3387 clash with some math-log functions. The YAZ header log.h defines logf
3388 to yaz_log (#define) so there should be no incompatibilities by this
3391 Added bend_start/bend_stop handlers for server. These handler are
3392 called on start/stop of server. For windows they are called whenever
3393 a service is started/stopped.
3395 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3396 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3397 in util/yc.tcl. The auto-generated C code structures are, in a few
3398 cases, incompatible with the old decoders. There are differences in the
3399 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3400 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3401 The preprocessor variable ASN_COMPILED is defined when the compiled
3402 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3403 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3404 wish to use the old encoders/decoders you can specify --disable-yc
3407 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3408 version so that it supports both new - and old version of DB Update
3410 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3411 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3412 change. The name parameter can be set to 0 in which no name is specified
3413 for the construction. The macros odr_implicit and odr_explicit sets name
3414 parameter to zero for the construction involved. New macros
3415 odr_implicit_tag and odr_explicit_tag are similar to the others,
3416 except that a name parameter is added. For programmers' that don't use
3417 ODR they probably only need to change the call to z_APDU and z_External.
3419 Added access control facility by interfacing the TCP wrapper library.
3420 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3421 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3422 name of the daemon and enables the access control as specified in
3423 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3425 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3426 den Dool <H.M.vdnDool@kub.nl>.
3428 Added reference ID parameter to most functions in server API - refer
3429 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3431 Changed name of ccl library to libccl.a (was ccl.a).
3433 Fixed bug in decoder for Explain (Category TargetInfo).
3435 Added support for GNU readline in client. Thanks to Jacob Poulsen
3436 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3438 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3439 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3440 IMPLEMENTATION! This change was made to the development version before
3441 the ZIG decided to retract the amendment. If any users MUST be
3442 compatible with the original Update definition, PLEASE CONTACT US, and
3443 we will include a separate definition corresponding to the old Update
3444 ES. Note that because of the change to the ASN.1 of the
3445 TaskPackageRecordStructure we cannot define a single structure that
3446 will support both versions.
3448 * Added const modifier to buffer parameter for some ODR/BER encoding
3449 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3450 completeWAIS, odr_dumpBER.
3452 Fixed bug in client.c which caused a crash when a scanResponse didn't
3453 contain positionOfTerm.
3455 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3456 * will cause an error in a client if a non-YAZ target sends both a
3457 * list of Scan entries and non-surrogate diagnostics.
3459 Retrieval module enhancements. Tag sets may be typed in the reference
3460 to it. From the .abs-file the "tagset" directive takes a third optional
3461 integer type for the tag set referenced. From a .tag-file the "include"
3462 directive takes a third optional type as well. The old "type" directive
3463 in the tag set itself is still recognized but acts as the default type
3466 Backend interface change. Individual Scan terms returned from bend_scan
3467 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3468 in include/backend.h.
3470 Retrieval module enhancements. Multiple tag sets and attribute sets may
3471 be specified in abstract syntax specs. Revised the error/warning for
3472 logging messages reported by the retrieval module when reading the
3475 Object Identifier system (oid_..) changed. The API is backwards
3476 compatible but the oid-routines now allocates new OID's when needed.
3477 Raw OID's may be specified in oid_getvalbyname.
3479 YAZ now uses GNU configure to generate Makefile(s).
3481 * Minor changes in some of the member names of DeleteResultSetRequest and
3482 DeleteResultSetResponse. See include/proto.h.
3484 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3485 and added member 'languages' in TargetInfo (which was missing).
3487 Changed the way attribute sets are handled in the retrieval
3488 module. These are now cached, just like the abstract syntaxes
3491 Changed YAZ so that it links with compiled ASN.1.
3493 Added Explain-schema definitions and mapping routines. The following
3494 Explain categories have been implemented: AttributeDetails,
3495 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3497 Fixed minor bug in Windows version of Server Library.
3499 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3501 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3503 Added EXTERNAL: UNIverse Resource Report (non-standard).
3505 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3506 ENUMERATED and SET OF.
3508 * Added 'const' to some of the char pointer arguments for the
3509 functions, data1_read_node, data1_getelementbytagname,
3510 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3513 Fixed bug in data1_insert_taggeddata - the last_child member of
3514 parent wasn't initialised.
3516 * Changed data1_read_record and data1_read_node so that the supplied
3517 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3518 doesn't refer to any parts of the "SGML"-buffer.
3520 Fixed bug in server library (Windows version of statserv_remove).
3522 * Changed code so that it compiles as C++. The type definition
3523 of Odr_fun which is a member of Odr_arm was changed. The result is,
3524 that an explicit typecast is needed for the fun pointer when
3525 using Odr_arm - as in:
3526 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3528 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3530 Implemented the new structured date and time definition as approved
3531 by the ZIG. Added schemaId element to the specificTag in Espec-1
3532 (also approved at the last ZIG). Thanks to RVDM.
3534 Added some Object identifiers (RVDM).
3536 Changed the Update Extended Service (RVDM).
3538 Added command "refid" to client which specifies referenceId for
3539 the following requests.
3541 Implemented extended service handling for server. See ztest.c
3542 for an example as well as backend.h. New handlers are registerd
3543 in the Init handler.
3545 * Changed interface for sort in server.
3547 Added new members to statserv_options_block. It allows a server
3548 to read options from another source than just the command line. Thanks
3549 to Charles Woodfield.
3551 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3552 renamed to zboolean. Some C++ compilers complained about the name.
3554 Minor changes to gils.abs. Added index 's' (sort) on title
3555 and date/time-last-modified.
3557 --- 1.4pl2 1998/1/30
3559 Fixed bug in server library regarding inetd mode (-i). This bug
3560 was introduced by release 1.4.
3562 --- 1.4pl1 1998/1/29
3564 Added sort facility in client and backend server interface.
3566 Fixed problem with dependencies in Makefile(s).
3568 Fixed bugs for encoders/decoders of extended services and
3571 Implemented sub-tree feature for schemas. Sub-trees are
3572 referenced in *.abs-files. See explain.abs for an example
3573 of the use of this feature.
3575 Modified bib1.att; local attributes for ANY didn't include
3576 ANY itself (only affects use of the retrieval module).
3578 Fixed bug in plain SGML reader in function data1_read_node:
3579 tags with prefix "var" was incorrectly interpreted as variants.
3581 Added feature "sub-schemas" to enable references to - and definitions
3582 of - group of elements.
3584 * Removed member parent from type data1_element (in data1.h).
3586 Implemented function odr_nullval() that returns the value of
3589 * Removed member num_children from data1_node (in data1.h).
3591 Made NT service interface part of the server library. The
3592 function statserv_main uses the NT service when required and
3593 calls the statserv_start / statserv_close routines.
3595 Routine zget_SearchRequest and zget_PresentRequest fills
3596 resultSetName/Id member with "default" instead of "Default".
3598 Fixed memory leak in server. Request queue member wasn't freed.
3600 Fixed nmem_exit so that memory is freed.
3604 Revised the CCL parser utility to be thread safe.
3606 Added function, oid_ent_to_oid, to replace the function
3607 oid_getoidbyent, which is not thread safe.
3609 * Added nmem_init and nmem_exit to initialize and release
3610 NMEM resources. Function nmem_init should be called once in the
3611 initial thread before NMEM/ODR is used. statserv.c and client.c
3612 have been changed accordingly. The change was necessary to make
3613 NMEM thread safe. The NMEM memory pool is shared amongst threads
3614 in a process. Unix-based applications will still work fine without
3617 Added NT Services interface for the the Z39.50 (statserv) Server.
3618 Refer to the ztest.c source on the usage.
3620 Windows 95/NT port using MSVC5.0. Project files are included in the
3623 * Defined new 'global' handle for the retrieval (data1) system. The
3624 new handled, data1_handle, describes the state of the data1 system.
3625 This handle is passed as first argument to virtually all
3626 data1 related routines. The functions data1_create and data1_destroy
3627 creates and destroys a data1 handle respectively.
3629 Added ODR encode stream member to all backend request structures
3630 init, search, scan etc. This stream should be used to allocate all
3631 memory used for the response when thread safe operation is needed.
3633 Changed the comstack utility, cs_addstr, to be thread safe. The
3634 returned hostname string returned by the function is now part the
3637 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3638 function. The cs_straddr takes a COMSTACK handle as argument, so this
3639 function must be used after cs_create and before bind/connect.
3640 This function is thread safe.
3642 Moved test server to 'ztest' directory - generic server code still
3643 in 'server' directory.
3645 Made prefix query (pquery.c) utility thread safe.
3647 Added new function modifier YAZ_EXPORT to 'export' public DLL
3648 functions when using windows (see include/yconfig.h).
3650 Added definitions to the OID database (util/oid.c) (RVDM).
3652 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3654 Added call to ccl_rpn_delete in client program.
3656 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3657 release of RPN structure.
3659 Added support for C++, headers uses extern "C" for public definitions.
3660 With input from RVDM.
3662 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3663 Thanks to Ronald van der Meer (RVDM).
3665 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3667 Added support for private extensions to the OID database
3668 (oid_setprivateoids()). Thanks to RVDM.
3670 Added optional, physical ANY (key replication)
3672 Fixed null-reference problem in GRS-1 output filter.
3674 Proximity operator added to Prefix Query Format (PQF).
3676 In test client command "base" accepts multiple databases.
3678 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3682 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3684 Smallish bug-fixes in the new encoders/decoders (explain).
3686 Bug fixed in DeleteRequest.
3688 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3690 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3692 Added SOIF syntax (using private OID for now) to retrieval module and client.
3694 Added Update extended service.
3696 Added SearchResult-1 additional info structure.
3698 Added optional CCL (ISO8777) interpreter as separate module. Available
3701 --- 1.2 1996/6/10 (1st anniversary release)
3703 Added Summary record syntax. Lightly tested.
3705 Added OPAC record syntax. Untested.
3707 Added ResourceReport service encoders/decoders. Untested.
3709 Fixed bug in z_Unit - wrong tagging on unitSystem.
3711 Fixed bug in the DiagRecs decoder.
3713 Added options for max PDU size and session timeout to frontend-server.
3715 Added documentation of query-language parsers and other supporting utilities.
3717 [frontend-server] Added Attribute set to the bend_scanrequest API.
3719 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3720 surrogate diagnostics were generated.
3722 [retrieval] Allow multiple local values for attribute.
3724 [retrieval] Allow multiple attributes per element in .abs files. index type.
3726 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3728 --- 1.1pl2 1996/4/10
3730 Minor changes, mostly specific to Zebra's requirements (retrieval)
3734 Repaired bug in frontend server when running multiple listening
3735 endpoints in dynamic mode.
3737 z_External() now won't break if a known, ASN.1 value comes encapsulated
3738 in an octet-string. The value will pass through unmodified in an Odr_oct.
3740 Added a bit of code to the demo client to decode & display
3741 ASN.1-structured records represented in the octet-aligned branch of
3742 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3744 Added z_ext_getentbyref() to the ASN module. Doc updated.
3746 * Completed the SCAN definition in the ASN module. This may break SCAN
3747 code based on older YAZ-versions at compile-time. The fix is easy -
3750 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3751 under the SCAN definition. Remember to initialize this, server-people.
3753 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3754 that this does not extend to ODR and ASN.
3756 Comstack allows insertion of established socket (primarily for
3757 inetd-operation of servers). Doc updated.
3759 Front-end server can now start from the inetd in TCP mode. Doc
3762 --- 1.0pl4 1996/1/24
3766 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3767 the rank and record number.
3769 Adjustments to the frontend server.
3771 Fixed diagnostic BER dumper. It ignored the file argument.
3775 Various changes to retrieval module.
3777 Changed the union discriminators of the protocol files from enums to
3778 ints paired with #defines.
3780 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3783 *Changed operator in the RPN structure to 'roperator', again to avoid a
3786 Fixed problems in Explain decoders/encoders.
3788 --- 1.0pl2 1995/12/6
3790 Memory bug in log module fixed.
3792 --- 1.0pl1 1995/12/5
3794 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3796 Bug in Explain DatabaseInfo module fixed.
3798 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3802 The shift to v1.0 signals that we now consider the *core* functionality
3803 of YAZ reasonably stable (the core being more or less equivalent to
3804 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3805 tested (Explain not at all - though that will happen soonish).
3807 Minor changes to code to support Windows port.
3809 Various minor changes after we're getting to use GRS-1 & co. more.
3811 Added Espec-1 format.
3813 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3814 of the protocol and it cannot be selected when encoding (maps into 'string'
3815 when decoding). Needed to talk to some servers.
3817 Demo client can request simple element set names.
3819 Added Diagnostic Format encoders/decoders.
3821 Added simple Close handling to frontend server (no hooks for resource
3822 reporting yet), and demonstration client.
3824 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3826 --- 1.0b3 1995/08/24
3828 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3829 handled incorrectly when records were requested in the searchResponse. This
3830 will only affect you if you use the frontend-server.
3832 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3833 Test-client will ask for and print GRS1. Ztest will return dummy records
3836 Added Explain encoders/decoders to the service-level API. Untested.
3838 Added Extended Services: Item Order encoders and decoders to the Service-
3839 level API. Untested. We could use a recent copy of the pertinent bits
3840 of the ILL protocol to add those bits.
3842 Added diagnostic format 1 encoders/decoders to the service-level API.
3845 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3846 odr_cons.c, which causes a more correct output.
3848 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3849 was always set to 0 when no records were requested in the searchRequest.
3851 * Added better external-handling. This shouldn't harm old code that
3852 *encodes* externals. It can break code that looks for a
3853 'single-ASN1-type' representation, since those types that are known
3854 are now decoded immediately. Look at the SUTRS sample code in
3855 seshigh.c and client.c. Documentation updated.
3857 Handling of structured records in bend_fetchresponse. Length -1 marks
3858 structured record, type is deduced from format field.
3860 --- 1.0b2 1995/06/27
3861 Fairly quick maintenance release to add SUTRS support.
3863 Fixed handling of SUTRS records in the demonstration client.
3865 * Added format field to the bend_fetchrequest and bend_fetchresponce
3866 structures of the backend API (frontend server). When the record is
3867 returned, the value of the format field is mapped to an OID. The
3868 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3869 of the record. The special value VAL_NONE in the bend_request means
3870 that no specific format was requested by the client. Documentation
3871 updated accordingly. Test server (ztest) will return a fixed dummy
3872 SUTRS record if your client requests SUTRS.
3874 Documentation updated accordingly.
3876 You can now set external libraries and RANLIB support in the top-level
3880 First public release.
