3 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
5 SRU GET/Solr base URLs may hold additional ?args YAZ-729
6 ZOOM option extraArgs already does this, though. It seems useful
7 when dealing with Solr targets to limit by filter, eg.
8 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
10 Remove #fragment for HTTP request encoding YAZ-730
12 Doc: Update list of DLLs/LIBs
14 Doc: update href link to Unix utils and Git.
18 ZOOM: fix "lost connection" problem with servers that uses both squid
19 and another proxy behind it that returns Location headers with relative
22 zoomsh: do not use readline for stdin (no tty) YAZ-724
23 Just use fgets in that case. If the user hits Ctrl-D a new-line
26 zoomsh: empty command ignored YAZ-723
27 rather than performing exit of zoomsh.
29 yaz-url utility offers option -v to enable verbose mode.
31 yaz_url uses yaz_check_location and offers verbose mode.
33 Add new function yaz_check_location.
34 This function gets an absolute URI from Location (HTTP redirect).
36 cookie API: introduce yaz_cookies_reset
38 Update cql.y for newer bison YAZ-720
39 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
40 longer supported. Instead one must use %lex-param and %parse-param .
44 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
47 rpn2solr: support truncation left(2), left&right(3) YAZ-718
49 Mention SRU version 2.0 in yaz-client man page.
53 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
58 Make cs_parse_host public.A
60 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
61 introduced in YAZ 5.0.6.
65 Fix buffer corruption for yaz-ztest record fetch.
69 Allow yaz-ztest to return user-defined records (one record per file).
70 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
72 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
73 Use the stream write instead of odr_printf which has a 4K tmp buffer.
75 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
79 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
80 can read and write this format. For record format JSON, yaz-ztest returns
83 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
84 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
88 Improve error reporting for ICU chains YAZ-707
89 Report config element+rule when ICU status is "failure".
91 ZOOM: stop fetching if present response has no records YAZ-710
92 Some targets return less records than their hit count would suggest.
93 This prevents ZOOM from continuing to fetch records if any present
94 response has 0 records in the response.
96 Ensure that GFS calls exit if any listener fails YAZ-710
97 Before, if XML config was in use, it would start the default
102 yaz-ztest: -V shows version (like yaz-client -V)
104 New iconv encoding: danmarc YAZ-692
106 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
108 daemon: only wait for immediate child rather than all children. YAZ-704
110 yaz-client: fix setting of SRU record schema. If scheme was unset, it
111 could lead to invalid memory reference.
115 yaz-ztest returns schema for MARCXML test records. SRU require that
116 recordSchema for records.
118 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
119 instead of non-surrogate diagnostic. This is a per-record failure.
121 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
122 may refer to multiple listeners now. Attribute listenref is a comma separated
125 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
126 option is given for GFS, the dirname of filename (for -f) is used
127 as prefix for options such as cql2rpn, ccl2rpn, etc.
129 Content-Type charset fixes YAZ-701 . Do not inspect charset in
130 Content-Type header for SOAP when decoding SRU. The payload (XML)
131 itself tells what encoding it is. In response, never supply encoding
132 in Content-Type. The response payload (XML) tells what it is (with no
133 encoding in XML it's UTF-8).
135 HTTP decoding: allow blanks in URL paths YAZ-700
139 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
140 and facets. Ensure recordData and recordSchema are always present in
141 record element, because they are required.
143 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
146 Simplify in a lot of places using odr_strdupn.
148 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
152 Increase various buffers in GFS's statserv_options_block
153 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
154 This change makes many type-casts redundant, and, thus simplifies code.
156 Remove last bits of WAIS support.
158 Remove member 'size' from Odr_oct.
160 Slim down the public part of 'struct odr'. Most elements are not part
161 of struct Odr_private.
163 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
164 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
165 In particular facets are supported in both client - and server side.
166 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
167 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
168 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
169 both request/response). This is what a search handler in the GFS
170 will see (regardless of whether operating in SRU mode or Z39.50).
172 Changes to the srw.h (SRU/Solr) definitions include:
173 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
174 (char*), which replace union query and query_type (int). This is because
175 SRU 2.0 supports a queryType parameter. This also means that, to carry
176 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
177 x-pquery=PQFstring (extention parameter). The extension parameter
179 - New element, packing, that has information about SRU
180 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
182 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
184 New element, packing, in Z_SRW_explainRequest.
186 New elements in Z_SRW_scanRequest, queryType and scanClause.
187 These replace query_type and scanClase untion. This is similar to what
190 --- 4.2.69 2013/10/01
192 GFS: log when closing down - at least SIGTERM YAZ-684
193 Also change formatting WRT PID logging a bit.
195 Improve display of MARC records with multi-byte subfield IDs YAZ-695
196 In some rare cases subfield identifiers are multi-byte characters.
197 This will try to deterime length of those and split accordingly.
198 This affects display in line mode as MARCXML/MarcXchange. The encoding
199 of ISO2709 is the same.
201 Change inp argument to const for yaz_read_UTF8_char.
203 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
205 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
207 Better check of marc leader info YAZ-691
208 Problem is that some systems generate MARCXML/MarcXchange with
209 funny headers. These will not work if encoded as ISO2709.
210 Some tests produce new output, due to updated warning messages
212 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
214 yaz-client: display MAB records YAZ-689.
215 Thanks for Heiko Jansen for this patch.
217 New utility z_get_HTTP_Response_server which allows both HTTP server name
218 and HTTP server URL to be given in response.
220 Debian: do not depend on obs tcl8.3.
222 Debian: do not depend on obs libicu36-dev.
224 --- 4.2.68 2013/09/23
226 GFS: pass additionalSearchInfo to search memeber search_input if
227 given. Otherwise pass otherInfo. Request for facets and other search
228 related things will be passed there in future versions of YAZ.
230 New ZOOM setting, authenticationMode, which allows authentication
231 paramters to be encoded in the URL rather than via HTTP Basic auth.
234 rpn2solr: fix nested AND/OR handling. YAZ-685
236 Add comparison routines for some Z-types, such as NamePlusRecord,
237 RPNQuery, Query, RecordComposition and OtherInformation.
239 --- 4.2.67 2013/09/19
241 Don't decode MAB as MARC. Just like we don't attempt to decode
242 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
244 CCL: allow quoted terms for date ranges. YAZ-681
246 Introduce ccl_parser_qual_search. This function makes old function
247 ccl_qual_search, from YAZ 2, available again.
249 Add yaz_facet_list_to_wrbuf. YAZ-683
251 --- 4.2.66 2013/09/11
253 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
254 schema was given for search. YAZ-675
256 Add Solr date range searches. YAZ-621
258 --- 4.2.65 2013/08/22
260 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
262 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
264 ISO2709/MARC parse most octet aligned records; not just those that
265 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
266 MARC parse more records instead of just dumping as is. YAZ-670
268 ZOOM: proper caching for variations of record schema. YAZ-671
270 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
272 --- 4.2.63 2013/07/17
276 --- 4.2.62 2013/07/11
278 New utility z_get_HTTP_Response_details - an extended version of
281 New utility yaz_url_get_error which returns error message of last
282 failed yaz_url_exec call.
284 yaz-url and url functions: allow max HTTP redirects to be controlled.
286 New functions yaz_file_glob2, yaz_xml_include_glob.
287 These functions takes a flags parameter, which, for now only controls
288 whether to fail inclusion of a non-existing file (without glob
289 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
291 --- 4.2.61 2013/06/20
293 For MARC XML parsing, allow record without leader. A fake/default leader
294 is inserted and a warning is tagged with the record.
296 ICU: fix leak in in icu_iter_get_org_info.
298 --- 4.2.60 2013/06/14
300 ICU: fix bug in icu_iter_get_org_info (un-init variable).
302 --- 4.2.59 2013/06/11
304 Implement z_HTTP_header_remove.
306 --- 4.2.58 2013/06/11
308 ICU: Disallow 0 ptrs for some ICU string utilities.
310 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
311 returns original tokens (before normalization).
313 CCL: avoid z39.58/regex truncation when not needed. Apply only the
314 conversion of those masks, when absolutely necessary.
316 CCL: configurable masking character - @mask. Default masking character
319 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
320 full response anyway, so a Transfer-Encoding header will obstruct the
323 --- 4.2.57 2013/05/15
325 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
326 picking a socket. Problem is that some systems has IPV6 support, but
327 we can't create sockets for them, so we pick AF_UNSPEC first.
329 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
330 use content_len to determine resulting Content-Length in HTTP response
331 and NOT Content-Length supplied in headers by user.
333 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
334 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
336 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
339 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
340 with big endian and unsigned char (by default).
342 --- 4.2.56 2013/04/26
344 Fix yaz-client connect (crash in 4.2.55).
346 --- 4.2.55 2013/04/26
348 Fix proxy/host problem for ZOOM that could occur if unix sockets
351 New Debian package libyaz4-dbg.
353 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
354 differently in tcpip_close.
356 --- 4.2.54 2013/04/17
358 Windows installer of YAZ includes YAZ4J as a component.
360 CQL: allow "extra terms" again, by default. Thus, the CQL parser
361 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
362 and earlier. CQL parser may operate in strict mode where queries
363 not conforming to the standard BNF are rejected (syntax error).
364 Whether the CQL parser operates in strict mode is controlled with
365 cql_parser_strict . Strict mode enabled with option -S for utilities
366 cql2pqf and cql2xcql .
368 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
370 --- 4.2.53 2013/04/10
372 New charset, MARC-8c, which is like MARC-8 but allows control characters
373 0x01 through 0x1F, except ESC to be passed through verbatim.
375 Fix a problem with duplicate sub field character in MARC output. Problem
376 happened only when output was MARC-8 encoded.
378 --- 4.2.52 2013/04/03
380 yaz-ztest: Use hash for fake hit count. Before, random number was used.
381 This is problematic for unit tests using yaz-ztest. This patch also makes
382 a hash for CQL queries. For RPN, any term with a leading digit will be
383 treated as pseudu hit count (to force any particular hit count by a client).
385 yaz-ztest: return unique MARC dummy records. Beyond record offset
386 24, the author surname is patched with offset to make all records
389 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
390 on system wide default (/proc/sys/net/ipv6/bindv6only).
391 @4 binds to IPV4 only. @6 binds to IPV6 only.
393 Update CQL API documentation a bit
395 CQL: don't accept extra terms for queries. Makes the CQL parser
396 stricly conformant to the standard.
398 --- 4.2.51 2013/02/12
400 GFS: scan handler gets extra_args from request and may return extra
401 response data . That's for SRU only.
403 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
405 --- 4.2.50 2013/01/30
407 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
409 OPACXML: sync spelling of availabilityDate in XML to that of Schema
410 opaxxml.xsd. The schema had the correct spelling of this member always.
411 The ASN.1 was mis-spelled and still is (API change) - we are
412 not changing this. However, the OPAC to XML conversion had yet
415 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
418 New function, z_ext_record_oid_nmem, which is similar to
419 z_ext_record_oid but takes NMEM rather than ODR
421 --- 4.2.49 2013/01/18
423 ICU: New conversion element 'join' which joins tokens into one
424 with a custom character given by rule attribute.
426 --- 4.2.48 2013/01/10
428 New GFS search member: present_number. This is a hint to the
429 search handler how many records are going to be fetched immediately
430 following search. There's no guarantee that it's going to be the case,
431 since it depends on hit count (for Z39.50 piggyback) and whether errors
434 Make a few functions static (private). The functions getbyte_stream,
435 ungetbyte_stream and yaz_gets are now private. They were never declared
438 yaz-marcdump: exit(5) for serious decoding errors
440 ISO2709 decoding: be more picky WRT header
442 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
443 was only used as to indicate that next-result-set-position should be
445 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
446 Based on patch from Ashley Sanders.
448 Make some functions static/private in PQF parsing. Those functions were
449 never declared in a public header and so should not be in use by
450 applications based on YAZ.
452 --- 4.2.47 2012/11/23
454 ZOOM: special options to control APDU logging.
455 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
456 logging of APDUs until "saveAPDU" option is set again. If logging is
457 already enabled the effect is that current APDU buffer is cleared.
458 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
459 logging (default behavior on new connection).
460 The APDUs sent/received can be obtained by using
461 Using ZOOM_connection_option_get(c, "APDU") or
462 ZOOM_connection_option_getl(c, "APDU", &l).
464 GFS: relay implementation_version from backend
465 From 3.0.40 and later, implementation_version from backend was
466 not used in init response at all.
468 --- 4.2.46 2012/11/15
470 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
471 mode at all. Probably never did.
473 Make a new version of ztest.pem that, at least, is not expired.
475 --- 4.2.45 2012/11/13
477 Fix description of CCL directive 'case'.
479 More tight checking of form arguments (yaz_uri_to_array). Makes
480 YAZ better at rejecting big and/or bad POSTs.
482 SRU decoding does not report more than up to 10 invalid arguments.
484 rpn2cql: less quotes in generated terms. Semantics unchanged, but
485 it's prettier this way.
487 --- 4.2.44 2012/10/25
489 New utility yaz_decode_init_diag. Defined in proto.h.
491 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
492 given for unix local socket.
493 The COMSTACK string for doing so is:
496 unix:/myfile:tcp:localhost:9999/mybase
497 unix:/myfile:localhost:9999/mybase
498 unix:/myfile:http://fakehost/mybase
500 debian: Use dpkg-buildflags in build process.
502 --- 4.2.43 2012/10/19
504 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
505 global's SRU service uses a recordPosition scheme starting from zero.
506 First record's position should be one
507 according to the standard.
509 --- 4.2.42 2012/10/18
511 Allow more namespaces for SRU. This is to allow, for example, an
512 incorrect namespace returned from server
513 http://services.igi-global.com/sru .
515 Minor fixes for compilation on Windows.
517 --- 4.2.41 2012/10/11
519 daemon: log total number of bad signals from child on stop so that it
520 is more easy to spot problems with child worker processes.
522 retrieval: empty backend name attribute omits element set
523 from being used in retrieval.
525 --- 4.2.40 2012/10/04
527 Implement Solr sort strategy "solr", similar to sru11 sorting.
528 This will implement the correct parameters on Solr requst to do
531 --- 4.2.39 2012/09/28
533 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
536 MARC: Extra/missing indicator handled for MARCXML.
537 The indicator length is given in header and is the same for the
538 whole record. If attributes ind1, ind2 are missing, then content
539 character defaults to blank. Extra indicator attributes (beyond)
540 indicator length are treated as an error.
542 Reformat: delete trailing whitespace
544 --- 4.2.38 2012/09/17
546 MARC: fix non-ASCII characters for leader. This is to ensure we can
547 generate XML in UTF-8.
549 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
550 in one node with structure word.
552 --- 4.2.37 2012/09/04
554 yaz-json-parse: JSON output may be pretty printed by using option
557 Increase default value of max message for Z39.50 Init for GFS, ZOOM
558 and yaz-client. Old value was 1 MB. New value is 64 MB.
560 --- 4.2.36 2012/08/22
562 yaz-client: don't display bogus records from SRU servers. Some SRU servers
563 return more records than given by *maximumRecords*. Skipping those in
566 record_render: simplify buffer return handling and fix at least one bad
567 memory reference, that broke the test_embed_record sometimes.
569 Allow http://user:pass@host notation for yaz_url_exec.
571 zoomsh: allow shell command to be executed. Via the system(3) call.
573 yaz_poll: Allow num_fds == 0
575 yaz-client: fix bad encoding of "itemorder item". The itemorder
576 item <no> - command forgot to use length of encoded Item Request
577 package. Error present since YAZ 3.
579 yaz-ztest: fix bad usage of session handle. Bug was introduced when
580 result sets were saved (271a9c83).
582 SRU recordPacking: guess record packing in response rather than looking
583 at the recordPacking element which, OF COURSE, changed semantics in SRU
586 Decode SRU 2.0 responses. The official namespace for responses, according
587 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
588 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
589 nature.com's server, however, usee namespace
590 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
591 we are now using a glob-expr to match up the namespace. ZOOM C and
592 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
593 I can not find a single real example showing the "real" namespace in
594 the documentation from OASIS. The namespace for requests is different
595 from responses, but this is not added to YAZ yet, when we don't encode
598 --- 4.2.35 2012/06/26
600 zoom/record_render: add support for Base64 decoding fo MARC records
601 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
602 which will decode base64 + ISO2709 marc-8 encoded material from text node
605 --- 4.2.34 2012/06/07
607 Add missing definitions ZOOM_resultset_get_facet_field_by_index
608 and ZOOM_resultset_facets_names.
610 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
613 Change APDU dump printing to avoid long leading blanks. For levels 16
614 or larger the level is shown and the indentation is truncated but
615 recursed with modula 8. This makes it still reasonable easy to read
616 - even for nested BER dumps.
618 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
619 return 0 (incomplete package) in case where the BER package was
620 considered too nested (return value of -2).
622 dumpber: lines of level 15 are not indented further. Two spaces per
623 indentation; indentation 15 or more is indented to a fixed indentation
624 and augmented with a level=<no> indication.
626 zoomsh: increase max size of command+args
628 GFS: No limit in RPN buf size in CQL to RPN conversion.
630 --- 4.2.33 2012/05/09
632 New function for daemon utility, yaz_daemon_stop .
634 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
636 --- 4.2.32 2012/04/25
638 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
639 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
641 --- 4.2.31 2012/04/23
643 YAZ daemon utility relays SIGUSR1 to child process.
645 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
646 would result in en empty database list - which in turn would result in
647 encoding failure for search.
649 Fix reading beyond string in yaz_sort_spec.
651 --- 4.2.30 2012/04/11
653 Add two new SRU diagnostics:
654 236: Access to specified database denied
655 1015: Init/AC: Maximum number of simultaneous sessions for Userid
657 Document the very useful ZOOM-C option "apdulog".
659 CQL to RPN: term may be passed through verbatim. This is enabled with
660 truncation.cql . The assumption being that the term is already CQL.
662 --- 4.2.29 2012/03/20
664 record_conv: leader spec may be given for marc element.
665 The leader spec is given as attribute leaderspec for element marc.
666 For example to convert a MARC21 record from MARC-8 to UTF-8:
667 <marc inputformat="marc" outputformat="marc"
668 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
670 record_conv: allow user-XSLT params. For example:
671 <xslt stylesheet="MARC21slim2DC.xsl">
672 <param name="myparameter" value="myvalue"/>
673 <param name="otherparameter" value="othervalue"/>
676 record_conv: fix error handling for missing marc charsets.
678 CQL: fix extra terms in wrong order.
680 --- 4.2.28 2012/03/06
682 record_conv: modify new API for conversion types. The conversion types
683 may be passed in new functions yaz_record_conv_configure_t and
684 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
686 Avoid mixed statement/variable declare; fixes compilation with Visual
689 --- 4.2.27 2012/02/28
691 Add non-standard SRU diagnostic: 235: "Database does not exist".
692 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
693 Update SRU to Bib-1 diagnostic maps accordingly.
695 CCL: add two new diagnostics for unsupported masking. The new
696 diagnostics are: "Embedded truncation not supported" and
697 "Single charcacter mask not supported".
699 --- 4.2.26 2012/02/23
701 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
703 --- 4.2.25 2012/01/11
705 Build YAZ for Ubuntu Oneiric.
707 CCL: allow parantheses for proximity operands. For example CCL query
708 (a) % (b) is now allowed.
710 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
711 marked dead, rather then being destroyed. If not, the session memory is
712 being free'd before the search/scan handler is finished. Also destroy
713 'request' memory in request_release rather than in various places,
714 which resulted in leaks from time to time.
716 --- 4.2.24 2011/12/21
718 cql_sortby_to_sortkeys: honor sort prefix.
720 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
721 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
722 The rpn2cql family of functions now always returns quoted CQL terms.
724 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
726 --- 4.2.23 2011/12/15
728 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
729 sequence is treated as one. For example, &&a=b&&&c& is identical to
732 --- 4.2.22 2011/12/05
734 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
735 APDUs for a connection to a WRBUF.
737 --- 4.2.21 2011/11/23
739 Fix cql_sortby_to_sortkeys. Completely broken before.
741 Make CCL's @truncation work again.
743 --- 4.2.20 2011/11/09
745 New ZOOM connection setting: tproxy. It's like proxy, but does not
746 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
747 to set resolved address + port for a connection outside ZOOM itself.
749 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
751 --- 4.2.19 2011/11/07
753 Fix uninitialized variable in Solr spell support (could cause SEGV
754 for SRU response decoding).
756 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
757 back-end's addinfo through into the ZOOM response addinfo.
759 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
760 they are separated by a colon and a space rather than simply
763 --- 4.2.18 2011/10/28
765 Add support for Solr spell-checking/suggestions through ZOOM.
766 If a Solr target has been configured correctly for spelling-checking
767 and suggestions, these will now be returned on the ResultSet option
768 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
770 --- 4.2.17 2011/09/28
772 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
773 with a flag whether to substitute escape sequences or not.
775 --- 4.2.16 2011/09/22
777 Fix nmem_strsplit_escape to substitute escape char properly.
779 New option for zoomsh -e , which makes it abort on first error and
780 return process exit code to indicate success/failure.
782 YAZ options utility supports special option -- which makes all it treat
783 all following arguments as non-options.
785 --- 4.2.15 2011/09/16
787 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
788 searched if absolute filename is given.
790 Fix conv_xslt() error-reporting when stylesheet is not found.
791 (The value of fullpath is meaningless in this situation.)
793 --- 4.2.14 2011/09/07
795 Fix problem in CQL sort node creation: un-initialized memory.
797 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
798 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
799 CQL sortby depending on whether Type-1 or CQL is actually sent to the
802 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
803 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
805 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
806 will make it possible to use both single-character mask (#) and wildcard (?)
807 in CCL . Throw diagnostic for left truncation because that is not supported
810 --- 4.2.13 2011/09/01
812 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
813 cases using escapes (\-sequences) and masking.
815 PQF parse fix: A trailing backslash followed by end-of-string (\0)
816 would result in a read one byte beyond string.
818 rpn2ccl may use Z39.50 masking for terms (t=z).
820 ICU check fix. Don't include library -lCrun on Solaris, unless present.
822 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
823 not --cppflags (which seeems like an error in icu-config).
825 --- 4.2.12 2011/08/27 RPM package only
827 cql2ccl: fix conversion of terms: operator characters were not
830 --- 4.2.11 2011/08/25 RPM package only
832 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
833 CCL parser will map both # and ? to their regular expression
834 quivalents (. and .*).
836 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
837 of reserved CQL characters.
839 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
840 is, so that they are passed through.
842 --- 4.2.10 2011/08/24
844 ZOOM SRU mode: more aggressive re-connect.
846 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
847 made available as a utility function, declared in <yaz/logrpn.h>
849 rpn2cql_structure() supports proximity nodes (except that the Type-1
850 proximity node's "exclusion" binary is ignored, as there is no way to
851 express that in CQL). Fixes bug #4564.
855 Fix SEGV that could occur if set command of zoomsh was given without
856 value (2nd argument).
858 Fix SEGV that could occur if unsupported transport was given for
859 COMSTACK - say https (when SSL was unavailable).
861 Build yaz-url on Windows too.
865 New utility to get web content. Header is url.h. A command line tool
866 yaz-url is part of the distribution and packages.
868 Fixes for SSL COMSTACK (when gnutls is in use).
870 New functions yaz_base64{encode,decode}. Header is base64.h.
874 ZOOM C includes HTTP response buffer as additional info if it fails
875 to decode the SRU response.
877 Make wrbuf_json_puts available.
881 zoom: throw diagnostic for invalid value for option "sru". Before a
882 bad SRU request was sent.
884 Adding new utility wrbuf_vp_puts.
886 Add cclxmlconfig.obj to win/makefile. It was missing completely.
890 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
891 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
892 redirect was used at the same time.
894 MARC line mode decoding: be less picky about length given - first
895 5 digits of header that is.
897 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
899 Changes to decoding of SRU records: a record with recordPacking=xml is
900 modified with a new root element <yaz_record> if the recordData contains
901 multiple children elements. This is to make the record XML parseable
904 RPN to Solr conversion: encode special characters.
906 Generic Frontend Server: fix uinitialized member, stepSize.
910 Fix a bug in SRU decoding of records.. The database records stored
911 had un-initialized memory, but it would only be seen with yaz_record_render
912 and type_spec="ext" .
914 Fix a bug in ccl_qual_dup introduced in 4.2.3.
918 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
922 Add new utilities to convert from CQL to CCL . These utilities have
923 prefix cql_to_ccl defined in cql.h.
925 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
926 lead to memory heap corruptions when ICU utilities were in use.
930 Make compilation work without Libxml2.
932 yaz-client: remove redundant blanks in display of searchResult-1 term
937 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
938 resulting CQL node (tree) in a new node CQL_NODE_SORT.
940 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
941 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
942 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
943 Note that the CQL sortby spec is only converted when the GFS is already
944 converting from CQL to RPN (cql2rpn element).
946 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
947 specify whether to collapse delimitors or not. The existing nmem_strsplit
948 do collapse (collapse parameter = 1).
950 Windows installer: For NSIS, set InstallDir depending on x86/x64.
952 Rename internal func yaz_use_attribute_create. While non-static, this
953 function is not declared in a public header.
957 Add -lCrun when linking with ICU on Solaris.
959 More quicks character set conversions for OPAC records.
963 fix problem with record_render: records were converted (character set
964 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
968 SRU: add methods for handling DADS SRU-proxy facets.
970 Separate OPAC record character set for ZOOM_record. yaz_record_render
971 allows a character set given as charset=from/opacfrom,to where 'from' is
972 the character set of a bibliographic record, 'opacfrom' is character set
973 of OPAC record and 'to' is the target character set.
977 yaz-client: show may XML format records. Command show followed by 'format'
978 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
981 src/stemmer.c: Avoid using unnamed union. It is not supported by some
984 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
987 Update yaz.spec to operate on both SLES11 / Centos 5.5.
989 RPM: Release includes 'indexdata' name. Use indexdata in release name so
990 this package can be distinguished from other vendors.
992 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
993 as determined by configure
995 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
997 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
998 returns no error and no record, the present request is considered
999 partial (only a subset of the records could be returned by backend), and
1000 so it is appropriate to set Present Status to partial-4.
1002 --- 4.1.2 2010/11/02
1004 Move yaz-config man pages to section 1.
1006 More documentation about Solr.
1008 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1009 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1010 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1011 peers on some Linux systems. However, in general that does not work
1012 so YAZ can not rely on that to work. Debian changed behavior in this
1013 respect from Debian lenny to Debian squeeze (still testing as of Oct
1015 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1017 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1019 --- 4.1.1 2010/10/05
1021 Fix yaz-config output: echo_source not set correctly by configure.
1023 --- 4.1.0 2010/10/05
1025 Solr Web Service support for yaz-client and ZOOM.
1027 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1029 --- 4.0.12 2010/08/17
1031 Z39.50 facet support. Facet specifications are passed for search in
1032 other-information with ASN.1 as defined in facet.asn and OID
1033 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1034 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1035 3 is limit (number of entries to get in response). yaz-ztest returns
1036 dummy facets if a client asks for them.
1038 --- 4.0.11 2010/07/09
1040 CCL fixes: bug 2895 and bug 3539.
1042 GR1-display: add comma in display - was removed by mistake in
1045 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1047 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1049 --- 4.0.10 2010/06/18
1051 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1052 result set from a connection. The result set will be on its own
1053 thereafter; no operations on it will perform retrievals from a target.
1054 Only cached copies are returned.
1056 ZOOM C:fix case for HTTP servers responding with Connection:close.
1057 Ensure that if there is a current task it is resumed (like fetching
1058 more records in a result set) . Bug #3484.
1060 PQF parser: use odr_atoi for Odr_int (not atoi)
1062 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1063 values that contain any non-digits are treated as string attributes
1064 (previously decoding only checked for leading character ([0-9]). PQF
1065 encoding: attribute string values are not surrounded by double-quotes.
1067 --- 4.0.9 2010/05/21
1069 New utility for managing threads - thread_create.h.
1071 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1072 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1073 but YAZ' implementation do.
1075 Fixes for yaz_cond-functions on Windows 7.
1077 DLL export more symbols.
1079 zoomsh: show record do NOT render opac.
1081 Remove *.la files from Debian and RPM packages.
1083 --- 4.0.8 2010/05/11
1085 Debian package libyaz-dev depends on libgnutls-dev again (was
1086 removed in YAZ 4.0.6, but due to Libtool it is still needed
1087 even though yaz-config do not list libgnutls libs).
1089 ZOOM: Use only one WRBUF for returning string results for
1090 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1092 ZOOM: ZOOM_connection do not use a shared pointer to
1093 ZOOM_resultset after ZOOM_resultset is destructed by
1094 user. Reverts to YAZ 4.0.4 behavior.
1096 --- 4.0.7 2010/05/04
1098 record-conv: fix problem with at least one XSL conversion -
1099 due to probably incorrect usage of XML XSL documents.
1101 --- 4.0.6 2010/04/29
1103 Fix yaz-config for static mode and the use of SSL (gnutls).
1105 --- 4.0.5 2010/04/29
1107 Forward decl timeval struct in mutex.h and gettimeofday.h.
1109 yaz-config: fix 'static' mode linking.
1111 --- 4.0.4 2010/04/28
1113 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1114 are wrappers for pthreads or Windows. For Windows these are put in
1115 a separate DLL: yaz_cond4.
1117 libyaz.la (whole source) is compiled with thread. If thread support
1118 is enabled enabled, all source of YAZ is compiled with treading support.
1119 This allows core utilities such as yaz_log to use thread facilities.
1120 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1121 thread utilities. This commit moves mutex utilities (mutex.c) from
1122 libyaz_server.la to libyaz.la.
1124 yaz-json-parse displays leading text until error.
1126 --- 4.0.3 2010/04/09
1128 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1129 patch from Giannis Kosmas.
1131 SRU: no longer URL encode SRU database. The URL for an SRU server is
1132 a URL and such is alreeady encoded - at least when given with leading
1133 http:// or https://. This reverts behavior to YAZ 3.0.50.
1135 Support for new MARC XML notation TurboMARC which like MARCXML is a
1136 complete representation of MARC/ISO2709.. This one, however, is more
1137 compact and allows for faster processing with XSLT. TurboMARC can be
1138 used in the marcdisp.h API, from the yaz-marcdump utility and from
1141 yaz-ztest can be configured - via the database - to perform certain
1142 delays when it performs operations search, present and single record
1143 fetch. This allows testers to make yaz-ztest act as a real or even slow
1144 Z39.50 server. Refer to the yaz-ztest man pages for details.
1146 --- 4.0.2 2010/03/09
1148 wrbuf_destroy allows NULL WRBUF passed to it.
1150 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1152 Add ZOOM_connection_close.
1154 No fixed size buffers for ZOOM shell - bug #3257.
1156 tstodr: make it work on s390 platform.
1158 New icu iterator-functions. The new icu_iter-functions makes it possible
1159 to use ICU chains from many threads.
1161 yaz-client: better syntax check for show command.
1163 --- 4.0.1 2010/01/26
1165 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1168 New simple local-file XML include facility which allows file glob-patterns.
1169 Refer to yaz/xml_include.h.
1171 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1174 ZOOM_record_get supports new parameter "format" which makes it format XML
1177 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1178 JSONText in ECMA-262) is JSONValue, not JSONObject.
1180 --- 4.0.0 2010/01/20
1182 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1183 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1185 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1186 POSIX/Unix builds .so with major version 4.
1188 Remove old LOG_-defines from log.h. They have been obsolete and
1189 undefined by default for the last 5 years.
1191 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1193 GFS: Remove socket (int *fd) from search_rr handler. The socket
1194 descriptor ptr is a facility that allowed a search handler to supply
1195 a socket which would serve as a callback - when search was complete.
1196 This facility has now been in use for years.
1198 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1199 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1200 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1201 returns 'const char *' rather than 'char *. The returned string is
1202 read-only and should not be modified by applications. COMSTACK cs_close is
1203 now a void function - it no longer returns int. No applications check for
1204 the value and the implementations has always returned 0.
1206 ZOOM: use size_t for scan hit counts and str size. Functions
1207 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1208 occ (hit count) and len (string length) are now of type size_t pointer
1209 rather than int pointer. This is to be able to represent large hit counts
1210 and to also just to use the proper type for string length (strlen result).
1212 New JSON parser. Refer to include/yaz/json.h .
1214 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1215 Used to be int in some cases. Many wrbuf_-functions used to return an int
1216 indicating some length.. These return values were never used. And so they
1219 ODR: odr_malloc, odr_total now takes size_t for size.
1221 clone_z_type: fix leak; occurred for encoding failures.
1223 --- 3.0.52 2009/12/03
1225 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1226 bug was introduced in 3.0.51.
1228 --- 3.0.51 2009/12/02
1230 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1232 tcpip comstack: fix leak for getaddrinfo.
1234 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1235 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1236 Decoding of SRU "path" database is performed by private function
1237 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1238 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1240 yaz-client: honor base command for SRU. Change when database setting
1241 is applied for SRU and ensure it is kept when a connection is reset.
1242 Change also the way errors are displayed or SRU (decoding of packages).
1244 --- 3.0.50 2009/11/02
1246 Add support for extra request / response data for SRU codecs and GFS.
1247 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1248 for extra data response buffer and length. For the GFS, both request
1249 and response data (XML) is carried in extra_args and extra_response_data
1250 for the search handler. Patch by Ko van der Sloot.
1252 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1253 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1254 10010). This fixes bug #2113.
1256 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1257 cmdfile included a 'quit' command that would result in a memory violation.
1259 --- 3.0.49 2009/10/01
1261 Make a number of functions defined in xmlquery.c static. These have
1262 never been declared in a public header file (yaz/xmlquery.h) and was
1263 made public by mistake.
1265 Improve speed of character conversions (iconv utilities). This makes
1266 conversions from MARC-8 faster.
1268 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1269 unless type desired is "raw". This will prevent type "xml" from
1270 returning ISO2709 .. Which obviously can not be XML parsed.
1272 Fix memory leak in ZOOM that would occur if option apdulog was used
1273 on a re-used connection.
1275 Frontend server logs HTTP requests.
1277 Frontend server now sends Z39.50 close when it times out (sesssion has
1278 been idle for too long). Versions 2.0.30 and earlier also sent close.
1279 But due to a mistake this was disabled in all versions after that, i.e.
1280 the server would just close the socket immediately.
1282 yaz-client emits a better message when receiving an unrecognised
1283 userInformationField.
1285 Skip zero-length subfields when decoding ISO2709. This rare case happens
1286 if a record has two FS characters in a sequence. Without this patch
1287 there would be a reference beyond char array in using_code_len fragments
1290 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1292 --- 3.0.48 2009/08/28
1294 The show command offered by the zoomsh command now takes a 3d optional
1295 parameter type which is what is passed to ZOOM_record. If the type
1296 argument is omitted, "render" is used.
1298 RPN to CQL conv may use USE string attributes (bug #2978).
1300 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1302 --- 3.0.47 2009/07/08
1304 Function yaz_xml2query allows a diagnostic element in the PQF XML
1305 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1306 code and additional info respectively.
1308 The BER BOOLEAN is now the integral type Odr_bool which still happens
1309 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1310 typedef'd to Odr_int. This is still an integral 'int', but it may be
1311 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1312 ASN-1 compiler as well as programs has been updated to use the new types.
1314 --- 3.0.46 2009/06/08
1316 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1317 only the bibliographic record was rendered. For type=opac, an OPAC
1318 record is only returned if it is present.
1320 iconv: small fix for encoding of advancegreek.
1322 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1324 yaz-client: option auto_reconnect=on really reconnects.
1326 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1328 server: avoid null ptr ref for for yaz_poll errors.
1330 build: fix RPM build for RHEL 5.3.
1332 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1334 --- 3.0.45 2009/03/31
1336 Fixed bug #2709: TCP connect returns Invalid argument.
1338 Fixed compilation for mingw.
1340 Honor charset for raw records (ZOOM_record_get).
1342 Fixed use of errno for threaded mode that was seen on Solaris 10.
1344 Fixed argument passing with blanks in value for Windows Service.
1346 Disable YAZ' own log rotate by default (no 1 GB limit).
1347 The variable l_max_size which specifies the log file limit is set to 0
1348 (DISABLED): This is due to the fact that YAZ is most often deployed using
1349 logrotate. Also YAZ can not perform log rotate because of unsufficient
1350 permissions (setuid).
1352 --- 3.0.44 2009/02/17
1354 List supported encodings in man page for yaz-iconv.
1356 Fixed missing SSL libs for --libs output
1358 Re-established OID record syntax application-xml. Nobody should use it
1359 but we don't want to change soname because of this symbol being absent.
1361 --- 3.0.42 2009/02/02
1363 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1365 Added member named_result_sets for init handler struct for the GFS. This
1366 allows a server to disable named result sets.
1368 Removed OID record syntax application-xml.
1370 Added support for rule-based transliterator for ICU wrapper of YAZ.
1372 Fixed bug #1902: yaz-icu XML output.
1374 Make YAZ checks Emacs friendly.
1376 BITSTRING value shows value. Bug #2346.
1378 ISO2709 decoding: skip control characters from indicator data.
1380 Omit sort key by default in yaz-icu's output.
1382 Allow combined single char options (again) for YAZ' options function.
1384 Utility yaz-marcdump got option to display YAZ version (-V).
1386 Allow YAZ to use ICU 3.4.
1388 Added new ICU test case which illustrates removal of diacritics.
1390 --- 3.0.41 2008/12/29
1392 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1394 --- 3.0.40 2008/12/29
1396 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1399 Fixed bug #2352: yaz-marcdump crashes for certain record.
1401 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1403 Added support for Danmarc2 to UTF-8 conversion.
1405 Added support for ISO5426 to UTF-8 conversion.
1407 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1408 implementation version.
1410 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1412 --- 3.0.38 2008/11/10
1414 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1415 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1417 ZOOM C now interprets databaseName option for ZOOM connection as path
1420 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1422 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1424 Dummy Libxml2 types no longer defined in headers of YAZ'.
1426 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1429 --- 3.0.36 2008/09/26
1431 Various ODR chapter fixes.
1433 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1435 Added missing source for Windows compilation, mutex.c.
1437 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1439 For SRU connections in ZOOM all records up to "count" are now fetched.
1441 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1442 in Windows due to bad error handling for Libxml2.
1444 Added facility for sending arbitrary records (ASN.1 any) using
1445 ZOOM C's Extended service update. Patch by Sam Reynolds.
1447 New options for ZOOM C's connection, logapdu which makes ZOOM log
1450 --- 3.0.34 2008/06/18
1452 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1454 --- 3.0.32 2008/06/12
1456 Fixed memory violation that could occur when decoding UTF-8. This bug
1457 was only present in 3.0.30 of YAZ.
1459 --- 3.0.30 2008/06/06
1461 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1462 GNU TLS is used by default (if found).
1464 yaz-ztest returns OPAC records if a client asks for OPAC.
1466 Improved speed of MARC-8 encoding.
1468 Added support for lossy and loss-less MARC-8 encoding.
1470 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1472 Added new Windows Service wrapper (sc).
1474 yaz-client's itemorder command may now send a file.
1476 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1478 Added new function yaz_log_xml_errors.
1480 Allow (but warn) unknown XML attributes in MARCXML parsing.
1482 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1484 The UTF-8 to MARC-8 conversion now uses a different set of characters
1485 for Greek symbols. Bug #2120.
1487 --- 3.0.26 2008/02/21
1489 Added yaz_daemon (daemon.h).
1491 Fixed bug #2068: pkg-config trouble
1493 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1495 --- 3.0.24 2008/01/28
1497 Document --with-xml2 option.
1499 Added OPAC XML XSD (etc/opacxml.xsd).
1501 Allow glob mask for name attribute in retrieval element for the
1502 generic frontend server's retrieval facility.
1504 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1505 except POLLIN/POLLOUT.
1507 Fixed error handling in cs_listen. Bug #2037.
1509 --- 3.0.22 2008/01/20
1511 Fixed version in yaz/yaz-version.h.
1513 Fixed bug #2027: Crash when closing connection.
1515 Changed configure so that ICU support is only enabled if only ICU
1516 and Libxml2 is available (because the ICU chain is XML based).
1518 --- 3.0.20 2008/01/15
1520 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1521 is built. Only this DLL depends on the ICU runtime.
1523 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1524 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1526 Changed license of CCL module to 'Revised BSD'. After consultation with
1527 remaining members of the original EUROPAGATE consortium, we are re-issuing
1528 the CCL module without a separate license. The software was developed by
1529 Index Data as part of a research project. The special license was included
1530 to help feed usage information back to the project consortium to support
1531 project evaluation. At this time, the project consortium has long-since
1532 disbanded, and the majority of the original principals have retired. At the
1533 same time, we have significantly modified the software during the following
1534 years, to the point where very practically no original code remains. To
1535 simplify re-use of the software, we have contacted those members of the
1536 consortium who could be reached, and agreed to re-issue the module as a
1537 proper part of the YAZ package.
1539 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1541 CQL closer to being version 1.2 compliant. CQL also allows free-form
1542 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1545 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1546 bug could make Extended services handling crash in the ZOOM layer. This
1547 bug was only present in YAZ 3.0.18.
1549 --- 3.0.18 2007/12/19
1551 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1554 yaz-marcdump reads and writes collection wrapped records.
1556 Handle OPAC for record conversion module.
1558 Fixes for ICU wrapper.
1560 Allow ICU libs to be controlled with --with-icu .
1562 --- 3.0.16 2007/11/12
1564 Added yaz_poll which is a wrapper for select/poll. When poll is available
1565 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1566 sockets to be in use.
1568 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1569 functionality through an XML based configuration (ICU chain). This system
1570 is useful for search facilities such as Pazpar2 and Zebra that needs to
1571 perform tokenization of indexed material. The ICU code in a separate
1572 library libyaz3_icu.a.
1574 Added HTTP tunnel facility for COMSTACK, bug #1752.
1575 This is a facility that allows a Web proxy, such as squid, to tunnel
1576 Z39.50 traffic. This facility is "transparent" to must applications
1577 using YAZ. It's enabled by using pseudo transport connect: followed by
1578 the proxy address, followed by command, then follwed by he regular
1579 "virtual" addresss. For example,
1580 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1582 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1584 --- 3.0.14 2007/09/21
1586 Fixed bad memory reference in ZOOM_record - cuased by member not being
1587 initialized. This was a problem only in YAZ 3.0.12.
1589 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1590 fields were not removed.
1592 Changed the way C code is generated from codetables.xml. Made a MARC-8
1593 conversion trie for each characterSet section rather than codeTable.
1594 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1595 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1597 --- 3.0.12 2007/09/12
1599 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1600 from ZOOM_record_error).
1602 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1604 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1606 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1608 Better SRW-to-Bib-1 diagnostic mapping.
1610 ZOOM C and yaz-client announces SRU version 1.2 by default.
1612 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1615 Fixed in yaz_sru_decode to allow other version than 1.1.
1617 --- 3.0.10 2007/08/22
1619 Added support for SRU scan for ZOOM.
1621 Added support for the use of the older versions or Extended Service
1622 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1623 set to the version , 1=first, 2=second, 3=third. The third version is
1624 what ZOOM C has used so far. And that, obviously, is the default.
1626 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1627 therefore in Zebra and in SimpleServer-based applications). The new
1628 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1629 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1630 which is passed into the back-end search callback function.
1632 Added support for HTTP Basic authentication in clients: the SRU/W
1633 codec encodes the username/password elements of the PDU structure
1634 appropriately, and these may be set using the "user" and "password"
1635 options in ZOOM-C applications (the same options that are used for
1636 Z39.50 authentication).
1638 --- 3.0.8 2007/06/25
1640 Fixed bug #1208: SSL appears to be broken in ZOOM.
1642 Fixed bug #1206: Libxml2 include path weirdness.
1644 Added oid_name_to_dotstring.
1646 Allow elementSetName to be specified for ZOOM C record update.
1648 Allow waitAction to be specified for ZOOM C based for Extended Services.
1650 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1651 syntax OID. Bug introduced in YAZ 3 series.
1653 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1655 --- 3.0.6 2007/06/06
1657 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1658 directory. yaz-client now reads commands from file given by option -f
1659 if specified; then tries to read .yazclientrc in current directory.
1660 Failing that, it reads .yazclientrc from user's home directory.
1662 Added support for correlationInfo Note and ID for Record Update via
1665 Added yaz-client command querycharset which specifies character set for
1666 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1667 (termListAndStartPoint).
1669 Charset ISO5428:1984 is an alias for ISO5428-1984.
1671 Implemented a way to perform scan in a result set using Z39.50. This
1672 is achieved by attaching the result set name in the characterInfo
1673 (type InternationalString) of OtherInformation in the Scan Request PDU.
1674 The result set is identified in the otherinformation by the new OID:
1675 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1676 This allows for scan in result set and faceted search . Zebra did some
1677 of this in the APT term using attribute type 8 and value being result
1678 set. Using the OtherInformation approach for this is cleaner and easier
1679 to work with in proxies and the like. This facility can be used in
1680 yaz-client using new command setscan which takes a result set as first
1681 argument, start position (APT) as second.
1683 Changed decoding of SRU XML packed records to deal with servers that
1684 have recordData with XML data with multiple root nodes. Also make
1685 comparison for recordPacking case insensitive. Again, one server
1686 returns "XML" where others return "xml".
1688 For SRU responses allow Content-Type application/xml as well as text/xml.
1690 --- 3.0.4 2007/05/21
1692 Fixed bug in character set conversion of BER strings. Bug introduced
1695 --- 3.0.2 2007/05/08
1697 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1699 For OID class, use oid_class consistently.
1701 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1704 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1705 character set for bibliographic information interchange". By Giannis Kosmas.
1707 Added documentation on new OID API.
1709 --- 3.0.0 2007/05/02
1711 Changes to generic frontend server interface: added new member
1712 'query_charset' for bend_initrequest structure. A backend init handler
1713 should set this member to its native character set for query terms.
1714 When defined, the frontend server logic will announce this character set
1715 to a client if the negotiationModel bit is set by the client. All server
1716 implementors are encouraged to specify this. If a backend server does not
1717 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1719 Added CCL utility to remove terms (stop words) from resulting RPN
1720 tree. This is handled by functions with prefix ccl_stop_words_ .
1722 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1723 terms in RPN queries.
1725 Clean-up the CCL API. Moved some internal structures from ccl.h to
1726 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1727 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1728 This is replaced by ccl_parser_find_str which takes a string instead.
1730 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1731 libyaz.la is the core of YAZ except the generic frontend server and
1732 does not depend on POSIX threads anymore. libyaz_server.la is the
1733 generic frontend server facilities and uses POSIX thread functionality
1734 if available. The libyaz.la no longer depends on POSIX threads because
1735 the number of global structures is limited. NMEM no longer re-uses blocks
1736 between threads ; it simply free's memory immediately but allocates in
1737 "large" chunks as usual. We don't expect any performance penalties
1738 because of this. The yaz_log system is still using a global log_level so
1739 caution must be taken when modifying it with yaz_log_init_.. +
1740 yaz_log_mask_str. This, however, should not cause any trouble because
1741 these functions are called during initialization of application code
1742 anyway. `yaz-config --libs server` returns libs for server applications;
1743 `yaz-config --libs` returns libs for non-server applications.
1745 New OID database - with public definitions in oid_db.h. Removed old OID
1746 database including the head oid.h and definitions such as enum oid_value
1747 and struct oident. The new OID database uses the same string names as
1748 before but the 'protocol' is gone. There are now only two representations
1749 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1750 converts from string to OID; functions with prefix yaz_oid_to_string
1751 converts the other way.
1753 Change to emit_term() in CQL-to-PQF query translation: when a term has
1754 the /regexp relation modifier, do not process it for leading and
1755 trailing "^" and "*", which have quite different meanings in regular
1758 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1759 write handlers no longer carries a 'last' parameter. This will make
1760 yaz_iconv flush "less" characters. A flush is performed by call to
1761 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1763 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1764 removed, because function yaz_query_to_wrbuf does the same.
1766 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1767 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1769 Deprecated MARC utility functions removed.
1771 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1774 Branch split: YAZ_2_1_55_branch
1776 --- 2.1.54 2007/03/16
1778 Fix to ZOOM-C so that transparent reconnection is properly handled on
1779 connections that are in asynchronous mode.
1781 Fixed compilation on OpenBSD 4.0.
1783 Large strings in GRS-1 records are now properly displayed in yaz-client.
1785 Added character conversion support for "advancegreek"; based on patch from
1788 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1789 sequence is met. Before the error was not set so it would be unknown.
1791 Adjust yaz-marcdump MARC reader so that it skips until record separator
1794 --- 2.1.52 2007/03/07
1796 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1797 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1798 fd_set structure used as a bitmask for the FDs to be selected on.
1800 Using ACX_PTHREAD macro to check for POSIX threads.
1802 Fixed have-vsnprintf check.
1804 --- 2.1.50 2007/02/23
1806 Fixes for configure on BSD. Bug #900.
1808 Added snprintf/vsnprintf wrappers for systems that don't have
1809 limits (heavens forbid).
1811 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1812 created before all previous tasks were completed and removed from the
1813 task queue, the new task could be removed by a mistake.
1815 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1817 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1819 Fixed bug #832: Problem with MARC/charset in yaz-client.
1821 Fixed bug #668: save command line history for yaz-client.
1823 Fixed bug #830: pkg-config support.
1825 --- 2.1.48 2007/01/23
1827 Extended ZOOM result set options with two options that may be read by
1828 a client: resultSetStatus and presentStatus with values as specified for
1830 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1832 Fixed bug #827: Using SSL fails on Debian etch.
1834 Fixed bug #826: Weird looking chars for set of MARC records.
1836 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1837 that is treated as an ItemOrder with itemRequest being an XML document
1838 external. The value of "doc" is the content.
1840 Extended the GFS search facility. New member of bend_search_rr
1841 'estimated_hit_count' signals that hits is known to be an estmate
1842 (higher or lower than real hit count). New member 'partial_resultset'
1843 signals that the search was partial (hit count is lower or equal than
1844 real hit count). For Z39.50, the information is stored in resultSetStatus
1845 member of SearchResponse APDU. For SRU, the information is signalled
1846 via SRU diagnostic 59: "Result set created with valid partial results
1849 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1851 --- 2.1.46 2007/01/13
1853 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1855 Added ZOOM_connection_peek_event.
1857 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1858 the following new functions:
1859 ZOOM_event_nonblock, ZOOM_connection_process,
1860 ZOOM_connection_get_{socket,mask,timeout},
1861 ZOOM_connection_fire_event_{timeout,socket}.
1862 The existing blocking event handler, ZOOM_event, is a wrapper for the
1863 + blocking ZOOM_event_sys_{poll,select}.
1865 Implemented function ccl_xml_config which parses XML version of CCL
1866 configuration (bug #798).
1868 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1870 Added timings utility (yaz/timing.h)
1872 --- 2.1.44 2007/01/03
1874 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1877 Fixed bug #779: Rotation of apdu.log fails.
1879 Fixed for character set conversions:
1880 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1881 Honor G1 set in MARC-8 decoding.
1883 --- 2.1.42 2006/12/17
1885 Fixed bug #775: char conversion does not handle Alternative UTF-8
1888 Implemented function yaz_marc_read_line which parses MARC line format
1889 records. There is a wealth of formats out there. So far, this function
1890 reads line records produced by yaz_marc_write_line.
1892 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1893 more generic and easier to remember(!) options: -i format and -o format
1894 which specifies input format and output format respectively - where
1895 format is one of "marc", "marcxml", "line", "marcxchange".
1897 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1898 does not print anything except warnings for records.
1900 For yaz-marcdump, added support for MARC split into files (-s) with a given
1903 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1904 spec, at http://www.loc.gov/standards/sru/record-update/
1905 This has changed the binary layout of the following structs:
1906 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1907 bend_update_rr . Patch by Ko van der Sloot.
1909 Added GFS utility function bend_assoc_is_alive which returns 1 if
1910 association is still alive (client is connected); 0 otherwise (client
1911 closed connection). This allows busy servers to stop working for
1914 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1915 been a separate piece of software. This version of ziffy has been modified
1916 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1918 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1920 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1921 Client code may now interrogate options such as "init_opt_sort" to
1922 find out whether the server claims to support various options.
1924 --- 2.1.40 2006/11/27
1926 Added utilities yaz_{set,get}_esn to set/get element set name from
1929 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1930 of YAZ and has been so since YAZ 2.1.10.
1932 Implemented ZOOM_record_error which returns error information for
1933 record (surrogate diagnostic).
1935 --- 2.1.38 2006/10/31
1937 Updates for SRU Update by Ko van der Sloot:
1938 1. Changed name from "operation" to "action"
1939 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1940 versions in the code, marked as 'backward compatible'.
1941 3. Added diagnostics for SRU Update.
1943 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1945 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1947 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1949 For GFS, fixed problem with SRU diagnostic 'First record position out of
1950 range' being issued for 0 hits.
1952 zoomtst10 part of Windows Build.
1954 --- 2.1.36 2006/10/13
1956 Implemented yaz_filepath_comp which splits a path into file path
1957 components (required by Zebra 2.0.3+).
1959 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1960 BSD inspired license until now so this should not have any real impact on
1961 anybody. See http://www.opensource.org/licenses/bsd-license.php
1963 Fixed bug #687: Missing log lines.
1965 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1968 Fixed bug #689: SRU diagnostics to be added.
1970 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1971 whether a connection is idle (no more work do do).
1973 --- 2.1.34 2006/10/04
1975 Change type of optval from long to int for invocation of setsockopt with
1976 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1978 Added support for specifying the max log file size for the Generic
1979 Frontend Server. The size is given with option -r.
1981 --- 2.1.32 2006/09/21
1983 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1985 --- 2.1.30 2006/09/17
1987 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1990 Fixed bug in Generic Frontend Server that could cause a server to stop
1991 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1993 For the generic frontend server, the maximum record size is used as maximum
1994 size of incoming packages (SRU + Z39.50). The value until was previously
1995 only used in Z39.50 Init negotiation and, later, in a session controlled
1996 sizes of records returned. This is controlled using -k option. It can be
1997 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1999 --- 2.1.28 2006/09/04
2001 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2004 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2006 New option for yaz-marcdump -lpos=value which allows setting a portion
2007 of MARC header to a certain value.
2009 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2011 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2012 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2014 --- 2.1.26 2006/08/15
2016 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2019 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2021 --- 2.1.24 2006/08/08
2023 Fixed MARC ISO2709 encoding routines to deal with character set
2026 Minor changes to GFS logging. Database included in search request log
2029 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2030 cached/multiple records.
2032 Shared libraries are built by default on Unix+configure.
2034 Changed cql2pqf transformation to use a different evaluation order. The
2035 new order is: always, relation, structure, position, truncation, index
2036 and relationModifier. Old order was: always, relation, relationModifier,
2037 structure, index, position, truncation. Note that the the latter ones
2038 override former ones for identical attributes.. The new scheme means that
2039 it is possible to override any existing attribute with a relationModifier.
2040 And also that it is possible to override everything for the index rule
2041 (except the ones listed in relationModifier). No order is perfect but this
2042 one, we believe, covers more real cases.. The "always" should have been
2043 called "default", since the attributes there can be overridden with all
2046 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2047 compilation phase, but also for yaz-config --cflags output. This allows
2048 us to have public headers with Libxml2 stuff in them . It should also,
2049 eventually, make Libxml2 checks redundant in packages using YAZ, such
2052 --- 2.1.22 2006/06/15
2054 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2055 stored in uri, message and details.. Previously diagnostics were stored
2056 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2057 compatibility.. but he's probably the only one affected, so.
2059 Added support for CCL, compiled on the client side, in ZOOM-C. This
2060 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2061 input; the resulting query objects can be used for for searching with
2062 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2064 YAZ' configure searches for OpenSSL by default.
2066 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2067 SL_CTX_use_certificate_file. See
2068 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2069 for more info. Thanks to Ko van der Sloot.
2071 --- 2.1.20 2006/06/02
2073 Bug #600: SRU GET, POST support for yaz-client. Introduced
2074 command 'sru' which selects method SOAP/GET/POST.
2076 Allow missingValueAction to be specified for the sortspec string -
2077 function yaz_sort_spec. By default, the missing value action is null.
2078 Use ! to specify "abort". Use = followed by stringvalue to specify default
2081 Ensured that Present-handler (if defined) is called in GFS before any call to
2082 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2083 searchRetrieve requests.
2085 Documentation for YAZ is now based on the Docbook XML/XSLT using
2086 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2087 is no longer depending on jade/openjade or docbook-to-man scripts.
2088 PDF is no longer part of the distribution - but can optionally be
2089 made using DSSSL/jadetex or FOP.
2091 Added retrieval handling support in Generic Frontend Server to support
2092 conversion between MARC/XML as well as XSLTtransforms. See
2093 etc/yazgfs.xml for an example.
2095 Added Authentication support to Generic Frontend Server in SRU
2096 mode. Authentication using HTTP Basic is supported, as is the use
2097 of 'x-username' and 'x-password' parameters in the request itself.
2099 Added support for a new character set MARC8s identical to MARC8 except
2100 that it converts combined characters to single Unicode characters in the
2101 Latin-1 range (when possible).
2103 --- 2.1.18 2006/04/24
2105 ASN.1 compiler 0.4: generates brief Doxygen file header for
2106 generated .h/.c files.
2108 Utility yaz_iconv now supports conversion to MARC-8.
2110 New facilities for the MARC module. The reading - and writing of
2111 content are separate methods for the yaz_marc_t handle. The following
2112 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2113 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2114 format). Write functions have prefix yaz_marc_write_.. The existing
2115 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2116 available. Removed support for OAI-MARC and simplexml (not the
2117 simplexml from PHP5).
2119 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2120 to be returned for this connection.
2122 --- 2.1.16 2006/03/31
2124 Allow multiple languages and charsets to be specified with
2125 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2126 negcharset iso-8859-1,utf-8
2128 Translation of proximity nodes from CQL into PQF now works.
2130 Moved to automake 1.8, 1.9.
2132 Added function yaz_log_set_handler which allows a log handler to be
2133 installed. This handler will be called for all log messages. Output
2134 to file is also produced; but that can be disabled by passing NULL
2135 fname to yaz_log_init_file.
2137 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2139 For SRW (including GFS), accept application/soap+xml as content-type
2142 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2143 produces NO stylesheet reference even if a default stylesheet is specified
2146 --- 2.1.14 2006/03/14
2148 Updated Windows package to include yazd.dll + yazd.lib for the
2149 Development component.
2151 If the environment variable YAZ_LOG is set, then it is used as a
2152 string indicating the default level of logging to use if not
2153 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2154 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2155 used as before. So, for example, to omit warnings from YAZ logging,
2156 export YAZ_LOG=-warn
2158 cql_transform() now map structure and other attributes before indexes,
2159 so that index-specific structures and other attributes can override
2160 defaults. So now a combination of mapping specifications such as:
2162 index.dc.date = 1=date-modified 4=5
2163 does the right thing.
2165 cql_transform() now also respects the "always" mapping specification,
2166 which establishes an initial set of attributes to be used for all
2167 terms except where overridden by more specific attributes associated
2168 with the index, relation or modifier.
2170 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2171 which mode to use; one of "post", "get" or "soap" (SRW, default).
2173 Fixes for yaz_iconv routines: changed trie-based character set conversions
2174 to use only non-negative values for bit fields due to Sun's C compiler not
2175 supporting negative values.
2177 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2178 sequences where not read correctly. Fix by Rustam Usmanov.
2180 Updated win/makefile to use options, settings which makes things
2181 compile with VS C 2005.
2183 --- 2.1.12 2006/02/01
2185 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2187 In ZOOM socket code, use select instead of poll on MacOSX.
2189 ZOOM-C now support client-side compilation of CQL into RPN that is
2190 sent to the server, enabling CQL to be used against all Z39.50
2191 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2192 ZOOM_query object, and submit it using ZOOM_connection_search().
2193 The CQL-to-RPN translation uses a configuration file, the name of
2194 which must be specified in the Connection's "cqlfile" option.
2196 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2197 function, which takes as its start-term parameter a ZOOM_query object
2198 (which may have had either CQL or RPN set into it).
2201 --- 2.1.10 2005/11/29
2203 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2204 GFS to support this as well. Backend handler, bend_srw_update, does the
2205 update work. Code contributed by Ko van der Sloot.
2207 Allow retrieval of Search Result-1 information in ZOOM by the use of
2208 options that are attached to a result set. ZOOM documentation updated
2211 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2212 UTF-8 conversion. Patch by Raj Patel.
2214 Added option -m to GFS to control formatting of timestamps in log file.
2216 Added 'exit' as synonym for 'quit' in yaz-client
2218 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2219 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2220 for the new members. Patch by Ko van der Sloot.
2222 Added support for SRU POST. It is supported for content-type
2223 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2225 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2226 Instead make the library libyaz.la multi-threaded. Threading as a whole
2227 can still be disabled by configure option --disable-threads. Previosly,
2228 with older GLIBCs there were problems with MT libs under Apache. This
2229 has now been fixed a long time ago.
2231 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2234 CQL module modified to be case insensitive for relations/indexes/operations.
2236 Fixed bug in CQL transform code: incorrect value relationModifieder
2239 Added 'show all' command for yaz-client which retrieves all results
2242 Added new yaz-client, xmles, which takes a (private) OID and
2243 a document to be sent as an extended service request.
2245 Describe new yaz-client commands wait_response and set_auto_wait.
2247 Increase TCP/IP listener backlog from 3 (which I am guessing was
2248 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2249 that the socket will queue as many incoming connections as it's able
2250 to handle ongoing connections. In other words, it will never now
2251 refuse a connection that it would be able to handle merely because
2252 it's not got around to accepting() enough of the pending connections
2253 yet. This is the behaviour anyway under Linux, where the listen()
2254 argument is ignored; but not under BSD and on systems such as
2255 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2256 YAZ-based servers should now be uniform across operating systems in
2259 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2260 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2261 This allows yaz-marcdump to read large MARC batches (>2 GB).
2263 Modified all YAZ source files - except the source which is auto-generated
2264 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2267 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2268 corresponding to the existing *_setl() function. These allow option
2269 values containing arbitrary valuues.
2271 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2272 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2273 except that it returns an indicator of whether or not the sort
2274 criterion was accepted (0 for OK, -1 for invalid).
2276 --- 2.1.8 2005/06/07
2278 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2279 MARC output rather than returning "new" buffer.
2281 yaz-client warns about unknown init options.
2283 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2285 --- 2.1.6 2005/05/24
2287 Added support for SRW sort in Generic Frontend Server. Patch
2288 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2289 sortKeys - or NULL if none is provided.
2291 Fixed bug #307: It was impossible to specify indefinite/no timeout
2292 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2295 Added support for multiple languages and charsets to be specified in
2296 ZOOM. Each charset/language is separated by a blank. If negotiation is
2297 in effect in init-response, Option
2298 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2299 Code based on patch by Vasiliy Osadchuk.
2301 Fixed bug #306: infinite recursion that occurred when calling
2302 yaz_log_level_init as the first call (before other log level or
2305 Fixed bug in scan handling in front end server: if preferred-Position-In-
2306 Response was non-present, a NULL pointer referece was performed.
2308 --- 2.1.4 2005/04/26
2310 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2311 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2312 now defined for all those error codes. So instead of putting 109 in
2313 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2314 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2316 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2319 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2321 Program yaz-client now exits and produces an error message if multiple
2322 Z39.50 servers are specified on the command line (none or one allowed
2325 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2328 --- 2.1.2 2005/03/16
2330 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2332 Fixed bug #272: Preserve spacing for CCL terms.
2334 --- 2.1.0 2005/03/14
2336 Added support for virtual hosts and multiple backend servers for
2337 the YAZ frontend server. The configution is XML based and
2338 support specificition of CQL to RPN mappings and explain information.
2339 See section "Virtual Hosts" in the YAZ manual.
2341 Extended OPAC display utility. OPAC display utility renders
2342 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2343 to supplement yaz_marc_decode_wrbuf.
2345 Fixed a bug in MARC decoder that could caused it to crash for some
2346 invalid MARC records. More diagnostics and warnings where added in
2347 XML output (warnings, etc are stored in comments).
2349 --- 2.0.34 2005/02/08
2351 Fixes for UNIX domain sockets. Bug #261.
2353 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2355 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2356 Added yaz_marc_subfield_str which defines subfield lead string which is
2357 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2358 yaz_marc_endline_str which defines end of fields string used in
2359 YAZ_MARC_LINE format. Default string is newline.
2361 Experimental support for MarcXChange. This format can be produced
2362 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2363 http://www.bs.dk/standards/MarcXchange.xsd
2365 Added yaz-client commands scansize that sets maximum number of
2366 entries to be returned by scan.
2368 --- 2.0.32 2005/01/11
2370 Added support for SRW scan in yaz-client and Generic Frontend Server.
2372 * Added whereInList member to SRW Scan Term.
2374 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2376 Fixed NMEM system to return aligned blocks on the smallest boundaries
2377 that are suitably aligned for all possible types on the particular
2378 architecture YAZ is being built for.
2380 --- 2.0.30 2005/01/04
2382 Fixed numerious warnings that was issued with newer versions of GCC.
2384 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2385 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2388 Make YAZ Generic Frontend Server slightly faster.
2390 Enhance (and reduce) logging for Generic Frontend Server.
2392 Revert YAZ log system so that it flushes every write operation
2393 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2395 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2396 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2397 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2398 will effectively disable old definitions.
2400 --- 2.0.28 2004/11/09
2402 Added yaz_log_time_format which specifies log format using
2405 Added yaz_log_module_level which returns mask for a module. Value
2406 is non-zero mask a if module is enabled; zero if disabled.
2408 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2409 in include/yaz/cql.h.
2411 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2413 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2415 Fixed bug #172: RPM builds does not enable SSL.
2417 Doxyfile.in part of dist. Doxyfile generated by configure.
2419 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2420 are given and the corresponding component does not exist.
2422 Extend CCL documentation in YAZ reference. Describe r=r.
2424 --- 2.0.26 2004/10/01
2426 Fixed MARC->MARCXML conversion to properly deal with
2427 fields, subfields, indicators having non-ASCII characters.
2429 Fixed MARC->MARCXML conversion so that ASCII control characters
2430 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2433 Added YAZ GFS support for conversion from Z39.50 surrogate
2434 diagnostics to SRW surrogate diagnostics.
2436 Bug fix: YAZ GFS did not return schema in explainResponse.
2438 --- 2.0.25 2004/09/30
2440 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2441 now converts recordSchema to elementSetName as well as schema URI.
2443 Fixed bug in COMSTACK that prevented HTTP request packages from being
2446 --- 2.0.24 2004/09/29
2448 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2449 does not require white-space before and after the dash in a range, e.g.
2450 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2453 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2454 due to new GCC removing "redundant" code.
2456 Added yaz-client commands scanpos and scanstep that sets preferred
2457 position and step-size for scan.
2459 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2461 Added CCL utility ccl_qual_buf which parses one or more CCL
2462 spec lines in a buffer.
2464 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2465 of name and value - ignoring empty lines and comments.
2467 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2469 Added odr_get_element_path which returns current element path for an
2470 ODR handle. This utility is useful in error handling or user-defined
2473 Added ODR_PRINT utility odr_set_stream which is is a more generic
2474 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2475 to a write function and pointer to close function. The close function - if
2476 non-NULL - will be called during odr_destroy.
2478 Fixed bug in CCL parser where truncation char was not removed from
2479 right side when truncation=both was in effect.
2481 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2484 --- 2.0.23 2004/08/11
2486 Fix buffer overrun in CQL parser when dealing with proximity (%).
2488 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2489 to UTF-8/UCS conversion is now only based on codetables.xml.
2491 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2493 --- 2.0.22 2004/08/06
2495 Add support for more "commit changes" in ZOOM (uses Extended Services).
2497 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2500 Yet another small fix for configure of SSL.
2502 --- 2.0.21 2004/05/14
2504 Fix SSL libs for configure when --with-openssl=DIR is given.
2506 --- 2.0.20 2004/05/10
2508 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2510 SSL comstack now uses yaz.pem certificate file on server side
2511 by default. Certificate filename can be configured by calling
2512 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2514 Fix bug regarding multiple calls to ZOOM_connection_connect.
2516 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2518 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2519 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2521 ZOOM now allows inspection of X509 peer certificate for verification.
2522 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2524 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2525 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2526 as "modular" but it simplifies things.
2528 Added cs_get_peer_certificate to that returns peer X509 PEM.
2530 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2531 NULL if SSL is unavailable.
2533 Documentation about MARC decoding tools.
2535 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2537 --- 2.0.19 2004/03/30
2539 Rename CHANGELOG to NEWS to follow GNU style packing.
2541 Fix bug with missing initialization of member in init_diagnostics.
2542 This bug affects threaded version of GFS server.
2544 --- 2.0.18 2004/03/20
2546 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2549 Ensure zlib.dll is packed with Windows install.
2551 --- 2.0.17 2004/03/17
2553 Fix encoding of xsd:string to use text instead of CDATA.
2555 Fix endless loop in CQL parser with unbalanced ".
2557 Use a more compact way to store MARC-8 conversion tables.
2559 --- 2.0.16 2004/03/16 Debian only
2561 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2564 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2569 --- 2.0.15 2004/03/01
2571 Another fix for decoding of XML packed records.
2573 --- 2.0.14 2004/02/25
2575 Fixes for Chunked encoding. White space not ignored after length spec.
2577 Update NS and use default NS for SRW diagnostic elements.
2579 --- 2.0.13 2004/02/23
2581 Implement ZOOM_resultset_cache_reset which resets record cache.
2583 Implement ZOOM_resultset_sort which sorts a result set.
2585 Implement chunked HTTP transfer.
2587 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2589 --- 2.0.12 2004/02/16
2591 Added member 'schema' to bend_explain_rr structure so that backend
2592 can specify explain record identifier. Defaults to Zeerex 2.0.
2594 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2596 --- 2.0.11 2004/02/16
2598 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2601 Added init command for yaz-client which sends "extra" init request.
2603 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2604 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2606 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2608 Make ZOOM error code for "invalid query".
2610 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2612 --- 2.0.10 2004/02/05
2614 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2617 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2619 Added option -p <file> to make Generic Frontend Server to write PID file.
2621 Added option -D to put Generic Frontend Server in background on its own.
2623 Make ZOOM C recognize option "password". If unset, "pass" is used
2624 (for backwards compatibility).
2626 Fixed a bug in Generic Frontend Server that could make it crash if a
2627 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2630 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2631 Must be issued before open, in order to be in effect.
2633 --- 2.0.9-6 2004/01/12 Debian/Windows
2635 Make the SRU server more picky WRT unknown params, etc.
2637 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2639 New YAZ client command, options, that sets Z39.50 options.
2641 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2642 options from a string of tokens (one token for each option bit).
2644 Update SRW diagnostic code messages.
2646 --- 2.0.9-5 2004/01/07 Debian/Windows
2648 Handle user defined stylesheet for SRW/SRU.
2650 --- 2.0.9-4 2004/01/06 Debian/Windows
2652 Fix bug in decoding of Content-Length.
2654 --- 2.0.9-3 2004/01/06 Debian/Windows
2656 Fix a bug with decoding of XML packed records.
2658 --- 2.0.9-2 2004/01/05 Debian only
2660 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2662 Fix bug in SRW/SRU diagnostics decoding.
2664 --- 2.0.9 2004/01/05
2666 Fixed bug in Generic Frontend Server which could drop records exceeding
2667 preferred message size. Reported and fixed by Irina Dijour.
2669 Fixed calculation of package size for structured records in Generic
2670 Frontend Server. Reported and fixed by Irina Dijour.
2672 Fixed namespace for SRW/SRU diagnostics.
2674 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2676 --- 2.0.8 2003/12/22
2678 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2679 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2682 CQL changes to reflect recent changes to the specification:
2683 * Documentation talks about context sets instead of index sets.
2684 * Documentation talks about indexes instead of qualifiers.
2685 * The CQL-to-PQF transformer's configuration file now uses
2686 "index.set.name = <attributes>" instead of the old form
2687 "qualifier.set.name = <attributes>". (Both forms are still
2688 understood but the latter is deprecated.)
2689 * CQL terms with no explicit index specified are now interpreted as
2690 cql.serverChoice instead of srw.serverChoice (which of course
2691 behaves exactly the same.)
2693 --- 2.0.7 2003/12/16
2695 MARC conversion can now generate ISO2709 output in another
2696 character set. yaz-marcdump uses this facility if you invoke it
2699 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2700 functions from there can be used from C++.
2702 --- 2.0.6 2003/12/04
2704 Frontend server now transfers memory from decoded packages to stream
2707 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2708 references to show up.
2710 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2711 the ZOOM Abstract API. The older names for the same options are still
2712 also supported for the benefit of old applications.
2714 ZOOM-C supports "implementationId" and "implementationVersion" options
2715 to go along with "implementationName". These allow the user code to
2716 specify identification strings to be sent to servers.
2717 Add OID for the new ExtLite attribute set.
2719 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2720 as requested/supplid by Ere Maijala <ere@atp.fi>
2722 For generic frontend server, reverse the order of
2723 "toolkit-supplied / application-supplied" strings sent as implementationId,
2724 Name and Version. Also, remove the spaces around the slash. This brings
2725 the GFS in line with the behaviour of ZOOM-C on the client side.
2727 Add function ZOOM_scanset_display_term.
2729 yaz-client shows scan displayTerm if present.
2731 Utility yaz-iconv is now installed by default along with the man page
2734 Extend configure check for OpenSSL to use pkg-config where available (such
2737 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2738 server to specify uid/gid/mask for socket using the format
2739 unix:[user=uid,][group=gid,][umask=mask,]file=path
2740 If file= is omitted the existing format is assumed, e.g.
2742 in which case the mask is 0666 (rw for everybody).
2744 Major restructure of YAZ source. All source in libyaz is in src directory.
2745 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2746 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2748 Added man page for utility yaz-marcdump (used to be called marcdump).
2749 yaz-marcdump is installed by 'make install'.
2751 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2752 of incoming package failed.
2754 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2756 Change prototype of odr_perror: add const to message string.
2758 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2760 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2761 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2762 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2763 DNS lookup. There should not be any compatibility problems with this
2764 assuming that blocking=1 or 0 is used.
2766 Fix bad reference in UNIX comstack in function cs_addrstr.
2768 Fix for compilation on AIX.
2770 The generic front-end server (server/seshigh.c) now supports returning
2771 Init diagnostics to the client in User-information-field, in
2772 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2775 --- 2.0.4 2003/09/04
2777 Allow any CQL relation (not just all,any,exact,scr).
2779 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2780 that features the same UI.
2782 Implemented command update0 in YAZ client which is equivalent to
2783 update but uses old of Ext Update ASN.1.
2785 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2786 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2787 Previously no OID was used for this info.
2789 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2790 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2791 returns 'malformed search term' otherwise.
2793 SortResponse member resultCount now set to NULL in sort handler of
2796 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2799 Add three new utility functions for translating OIDs between various
2800 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2801 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2802 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2803 char *oid_to_dotstring(const int *oid, char *oidbuf);
2804 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2806 Reverted modifications for ES Update definition for z_IU0Update
2807 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2808 is back to YAZ 2.0.2.
2810 String value attributes for CCL parser.
2812 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2813 which their FirstSearch server returns in Init responses, sometimes
2814 carrying useful diagnostic information when Init fails. This has the
2815 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2816 "z39.50/oclcui.asn", where its definition is somewhat different from
2817 what OCLC document on their web-site, as required to interoperate with
2820 Support for anonymous authentication in yaz-client. Use the command
2823 * Fix the OID of the Index Data-local "admin" Extended Service from
2824 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2825 the 1000, which indicates a locally-defined OID, was a mistake.
2827 --- 2.0.3 2003/06/20
2829 Fix CCL directive @case handling so that it affects string match for
2830 both CCL keywords and qualifiers.
2832 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2833 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2834 Decoder has been updated with ASN.1 changes as listed in
2835 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2836 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2837 z_IUUpdate, remains unchanged.
2839 ZOOM_record_get may now return a record in a specific character set.
2840 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2841 "from" is the character set of record as returned by target. "to" is
2842 the character set to be returned. If omitted, "to" is UTF-8.
2844 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2846 New ODR utility, odr_getelement, which returns name of element for
2847 which encoding/decoding failed.
2849 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2850 in cases where a required element was omitted.
2852 Bug fix: some MARC8 sequences were not converted.
2854 New ZOOM option "step" which specifies number of records to be
2855 retrieved in one chunk. Used in conjunction with "start" and "count".
2857 SRW support for yaz-client. Use scheme http: to use it, e.g.
2860 yaz-client no longer does (un)intelligent character set conversions
2861 by default. Can be enabled with charset and marc_charset commands.
2863 xmalloc trace fix for 64-bit systems such as DEC alpha.
2865 Solaris 2.6 compile fix.
2867 New function, cql_strerror() translates SRW error codes, as returned
2868 by cql_transform_error(), into human-readable English strings. Used
2869 in yaz-client diagnostics when appropriate.
2871 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2872 converts it into a type-1 query which is sent to the server. This
2873 makes CQL available for use with all Z-servers, as opposed to the tiny
2874 minority that can handle CQL queries themselves.
2876 --- 2.0.2 2003/04/28
2878 New Debian package layout similar to the Redhat Package layout.
2880 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2881 and search result respectively.
2883 --- 2.0.1 2003/04/25
2885 Redhat package is now several packages: libyaz (runtime libraries),
2886 libyaz-devel (development and documentation, and yaz (utility programs).
2887 Package spec file by Morten Bogeskov.
2889 New member 'schema' in struct bend_fetch_rr which the name of requested
2890 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2891 handler MAY set this to reflect the schema of the returned record.
2893 New member 'display_term' in struct scan_entry. GFS now sets member entries
2894 and allocates scan entries to be filled by user scan handler. In previous
2895 version, entries member was allocated by the scan handler. That still works,
2896 but the GFS will ignore member display_term - assuming it was NOT set by
2897 the handler. The fact that the GFS now allocates the entries both allows
2898 for new members and makes a scan handler easier to write.
2900 Fix CQL lex buffer overflow.
2902 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2903 SRU default recordPacking is string.
2905 SRU protocol support for frontend server.
2907 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2909 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2911 Added scan for the ZOOM shell (zoomsh).
2915 * String Identifers for Schemas (Amendment 5).
2916 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2917 Old definition for schema
2918 Odr_oid *schema; /* OPT */
2923 Z_InternationalString *uri;
2924 #define Z_Schema_oid 1
2925 #define Z_Schema_uri 2
2928 * resultCount parameter to Sort Response (Amendment 1).
2929 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2931 Support for SRW 1.0 over HTTP. This is an optional feature and
2932 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2935 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2936 on the same port. SRW SearchRetrieveRequests are mapped
2937 to bend_init,bend_search,bend_fetch,bend_close.
2939 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2941 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2942 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2944 ZOOM connections are SRW based if schem http is used for hostname
2945 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2946 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2948 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2949 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2950 distance=n, order=true/false, relation=le, prox unit=word. If
2951 n is omitted, distance 1 is used.
2953 Fixed problem with C compiler include path in wrong order.
2955 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2956 on Solaris. Patch from Ko van der Sloot.
2958 New MARC decode API. All new functions operate on a yaz_marc_t
2959 handle. The most important new functions are: yaz_marc_create,
2960 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2961 decode and destroy respectively. Decoder can produce formats
2962 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2963 include/yaz/marcdisp.h.
2965 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2966 to UTF-8, UCS-32, wchar_t or Latin-1.
2968 * Prototypes for yaz_iconv_-functions moved to separate header
2969 include/yaz/yaz-iconv.h.
2971 Make a few private functions 'static' in unix.c. This prevents
2972 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2974 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2975 are set when Init Response is received.
2977 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2978 but returns diagnostic set as well.
2980 New function yaz_strerror which is a portable wrapper for
2981 strerror/strerror_r/GetLastMessage.
2983 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2984 is returned for MARC. If type is "oai", then OAI MARC is returned.
2986 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2989 --- 1.9.2 2002/11/26
2991 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2993 Fix bad race conditions on SIGTERM and terminate gracefully in
2996 Move retrieval (data1) module to Zebra since nobody seems to be
2999 Add GRS-1 render for ZOOM using same format as yaz-client.
3001 --- 1.9.1 2002/10/05
3003 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3005 Fix broken ESpec handling in data1 module.
3007 SGML reader parses comments and makes them part of the data1 tree.
3009 Added several type casts so that YAZ compiles as C++ code.
3011 ZOOM didn't handle PDU encoding failures properly.
3013 Added more Bib-1 diagnostics (approved extensions).
3015 GNU configure: better check for iconv.
3017 More portable use of accept, getpeername. Check for socklen_t. Use
3018 int/size_t if socklen_t is not defined.
3022 PQF parser rejects bad queries - including those with extra
3023 characters in them. PQF parser used to silently ignore that.
3024 Cleaner API for PQF added, which allows you to get detailed
3025 error information for bad queries (see yaz/pquery.h).
3027 Fixed bug in ZOOM_record_get for type "database".
3029 Implemented mini iconv library supporting conversions between
3030 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3032 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3034 --- 1.8.9 2002/08/20
3036 Fixed ZOOM C record cache so that preferredRecordSyntax and
3037 elementSetName is used to check for already fetched records.
3039 --- 1.8.8 2002/08/02
3041 Added three members in bend_initrequest structure to facilitate
3042 character set negotiation.
3044 Fixed a bug in frontend server that could cause indefinite
3045 loops under rare conditions.
3047 Revised character set utilities (charneg.h) so that encoding
3048 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3050 For PQF, directive @term <type> sets term type for Scan/Search.
3051 Here <type> is general, string, numeric, null. The term type
3052 is inherited - just like @attr.
3054 New call odr_set_charset that sets character set conversion for
3055 international-strings on a ODR stream. Prototype is:
3056 int odr_set_charset(ODR o, const char *to, const char *from);
3057 The InternationalString is still represented as C string in YAZ
3058 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3059 won't). On the protocol level, you can use any encoding.
3061 Support for UNIX sockets in ZOOM.
3063 Solaris recv sometimes returns errno == ENOENT. It is treated as
3064 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3066 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3067 both client and server. Code by Morten Bogeskov.
3069 --- 1.8.7 2002/05/22
3071 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3072 that they can be used directly from Visual Basic. You must recompile
3073 your windows APP if you're using ZOOM.
3075 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3076 Commands "lang" and "charset" sets language and character set respectively.
3077 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3078 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3080 Attributes from multiple CCL fields may be OR'ed rather than merged
3081 using directive "@field or". Fields are still merged by default -
3082 equivalent to "@field merge".
3084 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3087 Fixed bug in zget for parameter ExtendedServicesResponse.
3091 --- 1.8.6 2002/03/25
3093 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3095 Client displays USR.1:SearchResult-1 (hits per term).
3097 Additional Search Info for search in Generic Frontend Server.
3099 Fixed CCL parsing of "field=s".
3101 WIN32 installer - using the excellent NSIS software from nullsoft.
3103 Fixed CCL parsing of "field = - <number>".
3105 Added function yaz_marc_decode that decodes MARC for line mode
3106 display or XML (similar to that used by JZKit).
3108 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3109 Z39.50. But ISO/ILL was, however.
3111 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3112 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3114 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3115 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3117 --- 1.8.5 2002/02/03
3119 New YAZ client features: Command completion and new commands:
3120 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3121 Code provided by Jacob Poulsen.
3123 New call oid_trav, that visits all registered OIDs via callback.
3125 Function ZOOM_record_get now returns const char pointer rather than
3126 void pointer. It saves a lot of type casts.
3128 For YAZ client, command "auth" now allows you to set authentication
3129 in IdPass style. It is enabled when three tokens are given - order
3130 is user, group and password.
3132 Fix memory leaks in MARC record handling for ZOOM.
3134 New option for YAZ client, -k <kilobytes> that sets
3135 maximum record size. Similar to -k option for generic frontend
3136 server and yaz-ztest.
3138 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3140 Prefix query parser reports "fail" when bad attribute set is given.
3142 Fix in MARC decoder. Proximity logging. Fix for attribute set
3143 in scan handler for server. Patches by Shigeru Ishida.
3145 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3148 Configure option --with-openssl=<dir> now works when a directory is
3149 specified. Patch provided by Morten Bogeskov.
3151 New option for YAZ client, -u <auth>, that sets authentication.
3153 ZOOM fix: error information was sometimes "missing", since error
3154 was cleared/reset too when it shouldn't.
3156 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3158 --- 1.8.4 2002/01/04
3160 Scan for ZOOM API. New object ZOOM_scanset. New functions
3161 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3162 ZOOM_scanset_destroy.
3164 New ZOOM function, ZOOM_connection_last_event, that returns type
3165 of last event (such as "receive data", "send data", "apdu received",
3168 New ZOOM option, schema, that specifies schema for retrieval.
3170 New CCL feature. Qualifiers can be aliases for one or more
3171 other qualifiers (if more than one is given, OR is used).
3173 ZOOM uses named result sets if target supports it.
3175 Two new YAZ client commands: . (dot, which sources a script of YAZ
3176 client commands), and ! (to execute shell command.). Implemented
3179 Working on Debian packages.
3181 --- 1.8.3 2001/11/19
3183 YAZ client enables named result sets only if target supports it.
3185 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3187 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3188 with key="host" to get same result.
3190 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3191 Function Z3950_resultset_record(s) returns references to records
3192 "owned" by resultset. To become owner use Z3950_record_clone.
3194 Function z_ext_record handles Extended Services. Thanks to
3197 --- 1.8.2 2001/11/12
3199 CCL Parser fix: ignore token comma when dealing with and-lists.
3201 Documentation updates for COMSTACK.
3203 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3204 Changed prototype Z3950_records. For some functions, int parameters
3205 were changed to size_t.
3207 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3210 New MARC decode/display function, marc_display_exl, which properly rejects
3211 non-ISO2709 records. YAZ client uses it.
3213 --- 1.8.1 2001/10/29
3215 Fix bug: local attribute set wasn't set correctly in PQF strings.
3219 * Old Z39.50 codecs no longer supported.
3221 Added ZOOM C binding. See http://zoom.z3950.org/
3223 Renamed states for COMSTACKs to avoid confusion with events.
3225 Implemented cs_look and proper cs_rcvconnect.
3227 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3229 Configure detects POSIX threads on OpenBSD.
3231 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3232 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3234 When error is returned from present handler, non-surrogate diagnostic
3235 is returned in present response (and fetch handler is no longer called).
3237 * Minor adjustments to pquery parser (PQF). Token characters may be
3238 escaped by using backslash (C-style).
3240 PQF parser allows string attribute values to be specified. For @attr,
3241 non-numeric characters after the equal-sign are treated as strings
3242 (e.g. @attr 9=title).
3244 CCL trunction character may be defined (@truncation in file)
3246 * function zget_ExtendedServicesRequest sets waitAction to
3247 waitIfPossible (was wait).
3249 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3252 CCL operator names may be set in field definition files (CCL_bibset).
3253 See ccl/bib1 for an example.
3255 Fixes in ASN.1 compiler for C++ compatibility.
3257 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3258 and "op_or" to avoid conflict with C++.
3260 Fixed problem with GNU readline detection on Redhat 7.0.
3262 Added step-size for Scan backend handler.
3264 Fixed bug that made the frontend server crash when no attribute
3265 set was specified for scan.
3267 Front-end server automatically switches to original working directory
3268 when installed as an NT service. Previously -w had to be specified to
3271 Added extended attributes for retrieval module (data1), so that data1
3272 records carry d1_readXML/SGML attributes. d1_read also supports
3273 null-data rules ( <tag/>)
3275 On UNIX when POSIX threads are available, a separate library libyazthread
3276 is created. Programmers should link with that library and the yaz library
3277 when using threads. The reason for the split was that some applications
3278 on Linux, such as Apache, doesn't work well when using shared objects that
3281 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3282 (or any frontend server) in SSL mode by specifying ssl: followed by
3283 address. Only tested on UNIX.
3285 Added feature for CCL module. Virtual structure s=al or s=ol generates
3286 and-list and or-list respectively instead of phrase search.
3290 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3291 log_mask_str. This was done to avoid name conflicts with other libraries
3292 (such as other PHP extensions).
3294 Added raw OID member for preferred record syntax (request_format_raw)
3295 and returned record syntax (output_format_raw) for backend fetch method.
3297 Config file yaz-config now accepts options so that it returns specific
3298 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3300 Shared library support for UNIX using GNU libtool.
3302 * Modified backend interface. Request/Response struct's replaced by
3303 one read/write C struct. For example bend_fetchrequest and
3304 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3305 Every handler - even search has to be registered in bend_init
3306 handler. This means that the YAZ library no longer refers to
3307 external functions and it makes it possible to make the whole
3308 thing a single DLL/SO.
3310 Added Segment handler for backend server.
3312 Added Zmbol/Zebra administrative functions to YAZ client.
3314 Threaded frontend server on UNIX (when POSIX Threads are available).
3315 Starting the server with option -T enables multi-threading.
3319 Added configure option --enable-comp/disable-comp to control use
3320 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3321 located in sub directory asn.
3323 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3324 in ${exec_prefix}/bin along with the other programs yaz-client and
3327 GNU automake used to maintain makefiles.
3329 Added several OID's.
3331 Changed retrieval module so that we can load records with no abstract
3332 syntax defined. Tagpaths in these records are fully composed of string
3335 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3339 On UNIX, the generated makefile now supports a proper 'make install'.
3340 The prefix can be set via GNU configure to set the install location
3341 (default is /usr/local).
3343 * YAZ programs client and ztest were renamed to yaz-client and
3344 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3345 locations, such as /usr/bin,/usr/local/bin,etc.
3347 * YAZ Header files were moved from include to include/yaz. YAZ Header
3348 files are referred to as include <yaz/log.h> rather than <log.h>.
3349 The YAZ include path (-I ..) is therefore the same as before. Programmers
3350 should update their #include statements or use -Ipath/include/yaz
3351 instead. The main motivation for doing this change is that YAZ header files
3352 can be installed in "standard" locations /usr/include,/usr/local/include
3353 without introducing conflicts, since ALL YAZ header files are stored
3354 in subdirectory yaz (under /usr/include for example).
3356 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3357 rather than project/workspace files. We switched because project files
3358 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3361 Changed name of logging function, logf, to yaz_log, to prevent name
3362 clash with some math-log functions. The YAZ header log.h defines logf
3363 to yaz_log (#define) so there should be no incompatibilities by this
3366 Added bend_start/bend_stop handlers for server. These handler are
3367 called on start/stop of server. For windows they are called whenever
3368 a service is started/stopped.
3370 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3371 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3372 in util/yc.tcl. The auto-generated C code structures are, in a few
3373 cases, incompatible with the old decoders. There are differences in the
3374 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3375 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3376 The preprocessor variable ASN_COMPILED is defined when the compiled
3377 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3378 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3379 wish to use the old encoders/decoders you can specify --disable-yc
3382 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3383 version so that it supports both new - and old version of DB Update
3385 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3386 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3387 change. The name parameter can be set to 0 in which no name is specified
3388 for the construction. The macros odr_implicit and odr_explicit sets name
3389 parameter to zero for the construction involved. New macros
3390 odr_implicit_tag and odr_explicit_tag are similar to the others,
3391 except that a name parameter is added. For programmers' that don't use
3392 ODR they probably only need to change the call to z_APDU and z_External.
3394 Added access control facility by interfacing the TCP wrapper library.
3395 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3396 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3397 name of the daemon and enables the access control as specified in
3398 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3400 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3401 den Dool <H.M.vdnDool@kub.nl>.
3403 Added reference ID parameter to most functions in server API - refer
3404 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3406 Changed name of ccl library to libccl.a (was ccl.a).
3408 Fixed bug in decoder for Explain (Category TargetInfo).
3410 Added support for GNU readline in client. Thanks to Jacob Poulsen
3411 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3413 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3414 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3415 IMPLEMENTATION! This change was made to the development version before
3416 the ZIG decided to retract the amendment. If any users MUST be
3417 compatible with the original Update definition, PLEASE CONTACT US, and
3418 we will include a separate definition corresponding to the old Update
3419 ES. Note that because of the change to the ASN.1 of the
3420 TaskPackageRecordStructure we cannot define a single structure that
3421 will support both versions.
3423 * Added const modifier to buffer parameter for some ODR/BER encoding
3424 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3425 completeWAIS, odr_dumpBER.
3427 Fixed bug in client.c which caused a crash when a scanResponse didn't
3428 contain positionOfTerm.
3430 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3431 * will cause an error in a client if a non-YAZ target sends both a
3432 * list of Scan entries and non-surrogate diagnostics.
3434 Retrieval module enhancements. Tag sets may be typed in the reference
3435 to it. From the .abs-file the "tagset" directive takes a third optional
3436 integer type for the tag set referenced. From a .tag-file the "include"
3437 directive takes a third optional type as well. The old "type" directive
3438 in the tag set itself is still recognized but acts as the default type
3441 Backend interface change. Individual Scan terms returned from bend_scan
3442 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3443 in include/backend.h.
3445 Retrieval module enhancements. Multiple tag sets and attribute sets may
3446 be specified in abstract syntax specs. Revised the error/warning for
3447 logging messages reported by the retrieval module when reading the
3450 Object Identifier system (oid_..) changed. The API is backwards
3451 compatible but the oid-routines now allocates new OID's when needed.
3452 Raw OID's may be specified in oid_getvalbyname.
3454 YAZ now uses GNU configure to generate Makefile(s).
3456 * Minor changes in some of the member names of DeleteResultSetRequest and
3457 DeleteResultSetResponse. See include/proto.h.
3459 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3460 and added member 'languages' in TargetInfo (which was missing).
3462 Changed the way attribute sets are handled in the retrieval
3463 module. These are now cached, just like the abstract syntaxes
3466 Changed YAZ so that it links with compiled ASN.1.
3468 Added Explain-schema definitions and mapping routines. The following
3469 Explain categories have been implemented: AttributeDetails,
3470 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3472 Fixed minor bug in Windows version of Server Library.
3474 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3476 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3478 Added EXTERNAL: UNIverse Resource Report (non-standard).
3480 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3481 ENUMERATED and SET OF.
3483 * Added 'const' to some of the char pointer arguments for the
3484 functions, data1_read_node, data1_getelementbytagname,
3485 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3488 Fixed bug in data1_insert_taggeddata - the last_child member of
3489 parent wasn't initialised.
3491 * Changed data1_read_record and data1_read_node so that the supplied
3492 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3493 doesn't refer to any parts of the "SGML"-buffer.
3495 Fixed bug in server library (Windows version of statserv_remove).
3497 * Changed code so that it compiles as C++. The type definition
3498 of Odr_fun which is a member of Odr_arm was changed. The result is,
3499 that an explicit typecast is needed for the fun pointer when
3500 using Odr_arm - as in:
3501 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3503 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3505 Implemented the new structured date and time definition as approved
3506 by the ZIG. Added schemaId element to the specificTag in Espec-1
3507 (also approved at the last ZIG). Thanks to RVDM.
3509 Added some Object identifiers (RVDM).
3511 Changed the Update Extended Service (RVDM).
3513 Added command "refid" to client which specifies referenceId for
3514 the following requests.
3516 Implemented extended service handling for server. See ztest.c
3517 for an example as well as backend.h. New handlers are registerd
3518 in the Init handler.
3520 * Changed interface for sort in server.
3522 Added new members to statserv_options_block. It allows a server
3523 to read options from another source than just the command line. Thanks
3524 to Charles Woodfield.
3526 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3527 renamed to zboolean. Some C++ compilers complained about the name.
3529 Minor changes to gils.abs. Added index 's' (sort) on title
3530 and date/time-last-modified.
3532 --- 1.4pl2 1998/1/30
3534 Fixed bug in server library regarding inetd mode (-i). This bug
3535 was introduced by release 1.4.
3537 --- 1.4pl1 1998/1/29
3539 Added sort facility in client and backend server interface.
3541 Fixed problem with dependencies in Makefile(s).
3543 Fixed bugs for encoders/decoders of extended services and
3546 Implemented sub-tree feature for schemas. Sub-trees are
3547 referenced in *.abs-files. See explain.abs for an example
3548 of the use of this feature.
3550 Modified bib1.att; local attributes for ANY didn't include
3551 ANY itself (only affects use of the retrieval module).
3553 Fixed bug in plain SGML reader in function data1_read_node:
3554 tags with prefix "var" was incorrectly interpreted as variants.
3556 Added feature "sub-schemas" to enable references to - and definitions
3557 of - group of elements.
3559 * Removed member parent from type data1_element (in data1.h).
3561 Implemented function odr_nullval() that returns the value of
3564 * Removed member num_children from data1_node (in data1.h).
3566 Made NT service interface part of the server library. The
3567 function statserv_main uses the NT service when required and
3568 calls the statserv_start / statserv_close routines.
3570 Routine zget_SearchRequest and zget_PresentRequest fills
3571 resultSetName/Id member with "default" instead of "Default".
3573 Fixed memory leak in server. Request queue member wasn't freed.
3575 Fixed nmem_exit so that memory is freed.
3579 Revised the CCL parser utility to be thread safe.
3581 Added function, oid_ent_to_oid, to replace the function
3582 oid_getoidbyent, which is not thread safe.
3584 * Added nmem_init and nmem_exit to initialize and release
3585 NMEM resources. Function nmem_init should be called once in the
3586 initial thread before NMEM/ODR is used. statserv.c and client.c
3587 have been changed accordingly. The change was necessary to make
3588 NMEM thread safe. The NMEM memory pool is shared amongst threads
3589 in a process. Unix-based applications will still work fine without
3592 Added NT Services interface for the the Z39.50 (statserv) Server.
3593 Refer to the ztest.c source on the usage.
3595 Windows 95/NT port using MSVC5.0. Project files are included in the
3598 * Defined new 'global' handle for the retrieval (data1) system. The
3599 new handled, data1_handle, describes the state of the data1 system.
3600 This handle is passed as first argument to virtually all
3601 data1 related routines. The functions data1_create and data1_destroy
3602 creates and destroys a data1 handle respectively.
3604 Added ODR encode stream member to all backend request structures
3605 init, search, scan etc. This stream should be used to allocate all
3606 memory used for the response when thread safe operation is needed.
3608 Changed the comstack utility, cs_addstr, to be thread safe. The
3609 returned hostname string returned by the function is now part the
3612 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3613 function. The cs_straddr takes a COMSTACK handle as argument, so this
3614 function must be used after cs_create and before bind/connect.
3615 This function is thread safe.
3617 Moved test server to 'ztest' directory - generic server code still
3618 in 'server' directory.
3620 Made prefix query (pquery.c) utility thread safe.
3622 Added new function modifier YAZ_EXPORT to 'export' public DLL
3623 functions when using windows (see include/yconfig.h).
3625 Added definitions to the OID database (util/oid.c) (RVDM).
3627 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3629 Added call to ccl_rpn_delete in client program.
3631 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3632 release of RPN structure.
3634 Added support for C++, headers uses extern "C" for public definitions.
3635 With input from RVDM.
3637 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3638 Thanks to Ronald van der Meer (RVDM).
3640 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3642 Added support for private extensions to the OID database
3643 (oid_setprivateoids()). Thanks to RVDM.
3645 Added optional, physical ANY (key replication)
3647 Fixed null-reference problem in GRS-1 output filter.
3649 Proximity operator added to Prefix Query Format (PQF).
3651 In test client command "base" accepts multiple databases.
3653 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3657 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3659 Smallish bug-fixes in the new encoders/decoders (explain).
3661 Bug fixed in DeleteRequest.
3663 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3665 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3667 Added SOIF syntax (using private OID for now) to retrieval module and client.
3669 Added Update extended service.
3671 Added SearchResult-1 additional info structure.
3673 Added optional CCL (ISO8777) interpreter as separate module. Available
3676 --- 1.2 1996/6/10 (1st anniversary release)
3678 Added Summary record syntax. Lightly tested.
3680 Added OPAC record syntax. Untested.
3682 Added ResourceReport service encoders/decoders. Untested.
3684 Fixed bug in z_Unit - wrong tagging on unitSystem.
3686 Fixed bug in the DiagRecs decoder.
3688 Added options for max PDU size and session timeout to frontend-server.
3690 Added documentation of query-language parsers and other supporting utilities.
3692 [frontend-server] Added Attribute set to the bend_scanrequest API.
3694 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3695 surrogate diagnostics were generated.
3697 [retrieval] Allow multiple local values for attribute.
3699 [retrieval] Allow multiple attributes per element in .abs files. index type.
3701 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3703 --- 1.1pl2 1996/4/10
3705 Minor changes, mostly specific to Zebra's requirements (retrieval)
3709 Repaired bug in frontend server when running multiple listening
3710 endpoints in dynamic mode.
3712 z_External() now won't break if a known, ASN.1 value comes encapsulated
3713 in an octet-string. The value will pass through unmodified in an Odr_oct.
3715 Added a bit of code to the demo client to decode & display
3716 ASN.1-structured records represented in the octet-aligned branch of
3717 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3719 Added z_ext_getentbyref() to the ASN module. Doc updated.
3721 * Completed the SCAN definition in the ASN module. This may break SCAN
3722 code based on older YAZ-versions at compile-time. The fix is easy -
3725 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3726 under the SCAN definition. Remember to initialize this, server-people.
3728 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3729 that this does not extend to ODR and ASN.
3731 Comstack allows insertion of established socket (primarily for
3732 inetd-operation of servers). Doc updated.
3734 Front-end server can now start from the inetd in TCP mode. Doc
3737 --- 1.0pl4 1996/1/24
3741 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3742 the rank and record number.
3744 Adjustments to the frontend server.
3746 Fixed diagnostic BER dumper. It ignored the file argument.
3750 Various changes to retrieval module.
3752 Changed the union discriminators of the protocol files from enums to
3753 ints paired with #defines.
3755 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3758 *Changed operator in the RPN structure to 'roperator', again to avoid a
3761 Fixed problems in Explain decoders/encoders.
3763 --- 1.0pl2 1995/12/6
3765 Memory bug in log module fixed.
3767 --- 1.0pl1 1995/12/5
3769 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3771 Bug in Explain DatabaseInfo module fixed.
3773 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3777 The shift to v1.0 signals that we now consider the *core* functionality
3778 of YAZ reasonably stable (the core being more or less equivalent to
3779 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3780 tested (Explain not at all - though that will happen soonish).
3782 Minor changes to code to support Windows port.
3784 Various minor changes after we're getting to use GRS-1 & co. more.
3786 Added Espec-1 format.
3788 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3789 of the protocol and it cannot be selected when encoding (maps into 'string'
3790 when decoding). Needed to talk to some servers.
3792 Demo client can request simple element set names.
3794 Added Diagnostic Format encoders/decoders.
3796 Added simple Close handling to frontend server (no hooks for resource
3797 reporting yet), and demonstration client.
3799 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3801 --- 1.0b3 1995/08/24
3803 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3804 handled incorrectly when records were requested in the searchResponse. This
3805 will only affect you if you use the frontend-server.
3807 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3808 Test-client will ask for and print GRS1. Ztest will return dummy records
3811 Added Explain encoders/decoders to the service-level API. Untested.
3813 Added Extended Services: Item Order encoders and decoders to the Service-
3814 level API. Untested. We could use a recent copy of the pertinent bits
3815 of the ILL protocol to add those bits.
3817 Added diagnostic format 1 encoders/decoders to the service-level API.
3820 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3821 odr_cons.c, which causes a more correct output.
3823 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3824 was always set to 0 when no records were requested in the searchRequest.
3826 * Added better external-handling. This shouldn't harm old code that
3827 *encodes* externals. It can break code that looks for a
3828 'single-ASN1-type' representation, since those types that are known
3829 are now decoded immediately. Look at the SUTRS sample code in
3830 seshigh.c and client.c. Documentation updated.
3832 Handling of structured records in bend_fetchresponse. Length -1 marks
3833 structured record, type is deduced from format field.
3835 --- 1.0b2 1995/06/27
3836 Fairly quick maintenance release to add SUTRS support.
3838 Fixed handling of SUTRS records in the demonstration client.
3840 * Added format field to the bend_fetchrequest and bend_fetchresponce
3841 structures of the backend API (frontend server). When the record is
3842 returned, the value of the format field is mapped to an OID. The
3843 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3844 of the record. The special value VAL_NONE in the bend_request means
3845 that no specific format was requested by the client. Documentation
3846 updated accordingly. Test server (ztest) will return a fixed dummy
3847 SUTRS record if your client requests SUTRS.
3849 Documentation updated accordingly.
3851 You can now set external libraries and RANLIB support in the top-level
3855 First public release.
