3 Increase various buffers in GFS's statserv_options_block
4 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
5 This change makes many type-casts redundant, and, thus simplifies code.
7 Remove last bits of WAIS support.
9 Remove member 'size' from Odr_oct.
11 Slim down the public part of 'struct odr'. Most elements are not part
12 of struct Odr_private.
14 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
15 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
16 In particular facets are supported in both client - and server side.
17 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
18 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
19 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
20 both request/response). This is what a search handler in the GFS
21 will see (regardless of whether operating in SRU mode or Z39.50).
23 Changes to the srw.h (SRU/Solr) definitions include:
24 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
25 (char*), which replace union query and query_type (int). This is because
26 SRU 2.0 supports a queryType parameter. This also means that, to carry
27 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
28 x-pquery=PQFstring (extention parameter). The extension parameter
30 - New element, packing, that has information about SRU
31 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
33 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
35 New element, packing, in Z_SRW_explainRequest.
37 New elements in Z_SRW_scanRequest, queryType and scanClause.
38 These replace query_type and scanClase untion. This is similar to what
43 GFS: log when closing down - at least SIGTERM YAZ-684
44 Also change formatting WRT PID logging a bit.
46 Improve display of MARC records with multi-byte subfield IDs YAZ-695
47 In some rare cases subfield identifiers are multi-byte characters.
48 This will try to deterime length of those and split accordingly.
49 This affects display in line mode as MARCXML/MarcXchange. The encoding
50 of ISO2709 is the same.
52 Change inp argument to const for yaz_read_UTF8_char.
54 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
56 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
58 Better check of marc leader info YAZ-691
59 Problem is that some systems generate MARCXML/MarcXchange with
60 funny headers. These will not work if encoded as ISO2709.
61 Some tests produce new output, due to updated warning messages
63 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
65 yaz-client: display MAB records YAZ-689.
66 Thanks for Heiko Jansen for this patch.
68 New utility z_get_HTTP_Response_server which allows both HTTP server name
69 and HTTP server URL to be given in response.
71 Debian: do not depend on obs tcl8.3.
73 Debian: do not depend on obs libicu36-dev.
77 GFS: pass additionalSearchInfo to search memeber search_input if
78 given. Otherwise pass otherInfo. Request for facets and other search
79 related things will be passed there in future versions of YAZ.
81 New ZOOM setting, authenticationMode, which allows authentication
82 paramters to be encoded in the URL rather than via HTTP Basic auth.
85 rpn2solr: fix nested AND/OR handling. YAZ-685
87 Add comparison routines for some Z-types, such as NamePlusRecord,
88 RPNQuery, Query, RecordComposition and OtherInformation.
92 Don't decode MAB as MARC. Just like we don't attempt to decode
93 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
95 CCL: allow quoted terms for date ranges. YAZ-681
97 Introduce ccl_parser_qual_search. This function makes old function
98 ccl_qual_search, from YAZ 2, available again.
100 Add yaz_facet_list_to_wrbuf. YAZ-683
102 --- 4.2.66 2013/09/11
104 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
105 schema was given for search. YAZ-675
107 Add Solr date range searches. YAZ-621
109 --- 4.2.65 2013/08/22
111 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
113 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
115 ISO2709/MARC parse most octet aligned records; not just those that
116 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
117 MARC parse more records instead of just dumping as is. YAZ-670
119 ZOOM: proper caching for variations of record schema. YAZ-671
121 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
123 --- 4.2.63 2013/07/17
127 --- 4.2.62 2013/07/11
129 New utility z_get_HTTP_Response_details - an extended version of
132 New utility yaz_url_get_error which returns error message of last
133 failed yaz_url_exec call.
135 yaz-url and url functions: allow max HTTP redirects to be controlled.
137 New functions yaz_file_glob2, yaz_xml_include_glob.
138 These functions takes a flags parameter, which, for now only controls
139 whether to fail inclusion of a non-existing file (without glob
140 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
142 --- 4.2.61 2013/06/20
144 For MARC XML parsing, allow record without leader. A fake/default leader
145 is inserted and a warning is tagged with the record.
147 ICU: fix leak in in icu_iter_get_org_info.
149 --- 4.2.60 2013/06/14
151 ICU: fix bug in icu_iter_get_org_info (un-init variable).
153 --- 4.2.59 2013/06/11
155 Implement z_HTTP_header_remove.
157 --- 4.2.58 2013/06/11
159 ICU: Disallow 0 ptrs for some ICU string utilities.
161 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
162 returns original tokens (before normalization).
164 CCL: avoid z39.58/regex truncation when not needed. Apply only the
165 conversion of those masks, when absolutely necessary.
167 CCL: configurable masking character - @mask. Default masking character
170 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
171 full response anyway, so a Transfer-Encoding header will obstruct the
174 --- 4.2.57 2013/05/15
176 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
177 picking a socket. Problem is that some systems has IPV6 support, but
178 we can't create sockets for them, so we pick AF_UNSPEC first.
180 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
181 use content_len to determine resulting Content-Length in HTTP response
182 and NOT Content-Length supplied in headers by user.
184 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
185 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
187 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
190 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
191 with big endian and unsigned char (by default).
193 --- 4.2.56 2013/04/26
195 Fix yaz-client connect (crash in 4.2.55).
197 --- 4.2.55 2013/04/26
199 Fix proxy/host problem for ZOOM that could occur if unix sockets
202 New Debian package libyaz4-dbg.
204 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
205 differently in tcpip_close.
207 --- 4.2.54 2013/04/17
209 Windows installer of YAZ includes YAZ4J as a component.
211 CQL: allow "extra terms" again, by default. Thus, the CQL parser
212 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
213 and earlier. CQL parser may operate in strict mode where queries
214 not conforming to the standard BNF are rejected (syntax error).
215 Whether the CQL parser operates in strict mode is controlled with
216 cql_parser_strict . Strict mode enabled with option -S for utilities
217 cql2pqf and cql2xcql .
219 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
221 --- 4.2.53 2013/04/10
223 New charset, MARC-8c, which is like MARC-8 but allows control characters
224 0x01 through 0x1F, except ESC to be passed through verbatim.
226 Fix a problem with duplicate sub field character in MARC output. Problem
227 happened only when output was MARC-8 encoded.
229 --- 4.2.52 2013/04/03
231 yaz-ztest: Use hash for fake hit count. Before, random number was used.
232 This is problematic for unit tests using yaz-ztest. This patch also makes
233 a hash for CQL queries. For RPN, any term with a leading digit will be
234 treated as pseudu hit count (to force any particular hit count by a client).
236 yaz-ztest: return unique MARC dummy records. Beyond record offset
237 24, the author surname is patched with offset to make all records
240 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
241 on system wide default (/proc/sys/net/ipv6/bindv6only).
242 @4 binds to IPV4 only. @6 binds to IPV6 only.
244 Update CQL API documentation a bit
246 CQL: don't accept extra terms for queries. Makes the CQL parser
247 stricly conformant to the standard.
249 --- 4.2.51 2013/02/12
251 GFS: scan handler gets extra_args from request and may return extra
252 response data . That's for SRU only.
254 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
256 --- 4.2.50 2013/01/30
258 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
260 OPACXML: sync spelling of availabilityDate in XML to that of Schema
261 opaxxml.xsd. The schema had the correct spelling of this member always.
262 The ASN.1 was mis-spelled and still is (API change) - we are
263 not changing this. However, the OPAC to XML conversion had yet
266 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
269 New function, z_ext_record_oid_nmem, which is similar to
270 z_ext_record_oid but takes NMEM rather than ODR
272 --- 4.2.49 2013/01/18
274 ICU: New conversion element 'join' which joins tokens into one
275 with a custom character given by rule attribute.
277 --- 4.2.48 2013/01/10
279 New GFS search member: present_number. This is a hint to the
280 search handler how many records are going to be fetched immediately
281 following search. There's no guarantee that it's going to be the case,
282 since it depends on hit count (for Z39.50 piggyback) and whether errors
285 Make a few functions static (private). The functions getbyte_stream,
286 ungetbyte_stream and yaz_gets are now private. They were never declared
289 yaz-marcdump: exit(5) for serious decoding errors
291 ISO2709 decoding: be more picky WRT header
293 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
294 was only used as to indicate that next-result-set-position should be
296 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
297 Based on patch from Ashley Sanders.
299 Make some functions static/private in PQF parsing. Those functions were
300 never declared in a public header and so should not be in use by
301 applications based on YAZ.
303 --- 4.2.47 2012/11/23
305 ZOOM: special options to control APDU logging.
306 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
307 logging of APDUs until "saveAPDU" option is set again. If logging is
308 already enabled the effect is that current APDU buffer is cleared.
309 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
310 logging (default behavior on new connection).
311 The APDUs sent/received can be obtained by using
312 Using ZOOM_connection_option_get(c, "APDU") or
313 ZOOM_connection_option_getl(c, "APDU", &l).
315 GFS: relay implementation_version from backend
316 From 3.0.40 and later, implementation_version from backend was
317 not used in init response at all.
319 --- 4.2.46 2012/11/15
321 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
322 mode at all. Probably never did.
324 Make a new version of ztest.pem that, at least, is not expired.
326 --- 4.2.45 2012/11/13
328 Fix description of CCL directive 'case'.
330 More tight checking of form arguments (yaz_uri_to_array). Makes
331 YAZ better at rejecting big and/or bad POSTs.
333 SRU decoding does not report more than up to 10 invalid arguments.
335 rpn2cql: less quotes in generated terms. Semantics unchanged, but
336 it's prettier this way.
338 --- 4.2.44 2012/10/25
340 New utility yaz_decode_init_diag. Defined in proto.h.
342 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
343 given for unix local socket.
344 The COMSTACK string for doing so is:
347 unix:/myfile:tcp:localhost:9999/mybase
348 unix:/myfile:localhost:9999/mybase
349 unix:/myfile:http://fakehost/mybase
351 debian: Use dpkg-buildflags in build process.
353 --- 4.2.43 2012/10/19
355 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
356 global's SRU service uses a recordPosition scheme starting from zero.
357 First record's position should be one
358 according to the standard.
360 --- 4.2.42 2012/10/18
362 Allow more namespaces for SRU. This is to allow, for example, an
363 incorrect namespace returned from server
364 http://services.igi-global.com/sru .
366 Minor fixes for compilation on Windows.
368 --- 4.2.41 2012/10/11
370 daemon: log total number of bad signals from child on stop so that it
371 is more easy to spot problems with child worker processes.
373 retrieval: empty backend name attribute omits element set
374 from being used in retrieval.
376 --- 4.2.40 2012/10/04
378 Implement Solr sort strategy "solr", similar to sru11 sorting.
379 This will implement the correct parameters on Solr requst to do
382 --- 4.2.39 2012/09/28
384 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
387 MARC: Extra/missing indicator handled for MARCXML.
388 The indicator length is given in header and is the same for the
389 whole record. If attributes ind1, ind2 are missing, then content
390 character defaults to blank. Extra indicator attributes (beyond)
391 indicator length are treated as an error.
393 Reformat: delete trailing whitespace
395 --- 4.2.38 2012/09/17
397 MARC: fix non-ASCII characters for leader. This is to ensure we can
398 generate XML in UTF-8.
400 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
401 in one node with structure word.
403 --- 4.2.37 2012/09/04
405 yaz-json-parse: JSON output may be pretty printed by using option
408 Increase default value of max message for Z39.50 Init for GFS, ZOOM
409 and yaz-client. Old value was 1 MB. New value is 64 MB.
411 --- 4.2.36 2012/08/22
413 yaz-client: don't display bogus records from SRU servers. Some SRU servers
414 return more records than given by *maximumRecords*. Skipping those in
417 record_render: simplify buffer return handling and fix at least one bad
418 memory reference, that broke the test_embed_record sometimes.
420 Allow http://user:pass@host notation for yaz_url_exec.
422 zoomsh: allow shell command to be executed. Via the system(3) call.
424 yaz_poll: Allow num_fds == 0
426 yaz-client: fix bad encoding of "itemorder item". The itemorder
427 item <no> - command forgot to use length of encoded Item Request
428 package. Error present since YAZ 3.
430 yaz-ztest: fix bad usage of session handle. Bug was introduced when
431 result sets were saved (271a9c83).
433 SRU recordPacking: guess record packing in response rather than looking
434 at the recordPacking element which, OF COURSE, changed semantics in SRU
437 Decode SRU 2.0 responses. The official namespace for responses, according
438 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
439 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
440 nature.com's server, however, usee namespace
441 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
442 we are now using a glob-expr to match up the namespace. ZOOM C and
443 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
444 I can not find a single real example showing the "real" namespace in
445 the documentation from OASIS. The namespace for requests is different
446 from responses, but this is not added to YAZ yet, when we don't encode
449 --- 4.2.35 2012/06/26
451 zoom/record_render: add support for Base64 decoding fo MARC records
452 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
453 which will decode base64 + ISO2709 marc-8 encoded material from text node
456 --- 4.2.34 2012/06/07
458 Add missing definitions ZOOM_resultset_get_facet_field_by_index
459 and ZOOM_resultset_facets_names.
461 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
464 Change APDU dump printing to avoid long leading blanks. For levels 16
465 or larger the level is shown and the indentation is truncated but
466 recursed with modula 8. This makes it still reasonable easy to read
467 - even for nested BER dumps.
469 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
470 return 0 (incomplete package) in case where the BER package was
471 considered too nested (return value of -2).
473 dumpber: lines of level 15 are not indented further. Two spaces per
474 indentation; indentation 15 or more is indented to a fixed indentation
475 and augmented with a level=<no> indication.
477 zoomsh: increase max size of command+args
479 GFS: No limit in RPN buf size in CQL to RPN conversion.
481 --- 4.2.33 2012/05/09
483 New function for daemon utility, yaz_daemon_stop .
485 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
487 --- 4.2.32 2012/04/25
489 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
490 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
492 --- 4.2.31 2012/04/23
494 YAZ daemon utility relays SIGUSR1 to child process.
496 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
497 would result in en empty database list - which in turn would result in
498 encoding failure for search.
500 Fix reading beyond string in yaz_sort_spec.
502 --- 4.2.30 2012/04/11
504 Add two new SRU diagnostics:
505 236: Access to specified database denied
506 1015: Init/AC: Maximum number of simultaneous sessions for Userid
508 Document the very useful ZOOM-C option "apdulog".
510 CQL to RPN: term may be passed through verbatim. This is enabled with
511 truncation.cql . The assumption being that the term is already CQL.
513 --- 4.2.29 2012/03/20
515 record_conv: leader spec may be given for marc element.
516 The leader spec is given as attribute leaderspec for element marc.
517 For example to convert a MARC21 record from MARC-8 to UTF-8:
518 <marc inputformat="marc" outputformat="marc"
519 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
521 record_conv: allow user-XSLT params. For example:
522 <xslt stylesheet="MARC21slim2DC.xsl">
523 <param name="myparameter" value="myvalue"/>
524 <param name="otherparameter" value="othervalue"/>
527 record_conv: fix error handling for missing marc charsets.
529 CQL: fix extra terms in wrong order.
531 --- 4.2.28 2012/03/06
533 record_conv: modify new API for conversion types. The conversion types
534 may be passed in new functions yaz_record_conv_configure_t and
535 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
537 Avoid mixed statement/variable declare; fixes compilation with Visual
540 --- 4.2.27 2012/02/28
542 Add non-standard SRU diagnostic: 235: "Database does not exist".
543 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
544 Update SRU to Bib-1 diagnostic maps accordingly.
546 CCL: add two new diagnostics for unsupported masking. The new
547 diagnostics are: "Embedded truncation not supported" and
548 "Single charcacter mask not supported".
550 --- 4.2.26 2012/02/23
552 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
554 --- 4.2.25 2012/01/11
556 Build YAZ for Ubuntu Oneiric.
558 CCL: allow parantheses for proximity operands. For example CCL query
559 (a) % (b) is now allowed.
561 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
562 marked dead, rather then being destroyed. If not, the session memory is
563 being free'd before the search/scan handler is finished. Also destroy
564 'request' memory in request_release rather than in various places,
565 which resulted in leaks from time to time.
567 --- 4.2.24 2011/12/21
569 cql_sortby_to_sortkeys: honor sort prefix.
571 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
572 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
573 The rpn2cql family of functions now always returns quoted CQL terms.
575 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
577 --- 4.2.23 2011/12/15
579 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
580 sequence is treated as one. For example, &&a=b&&&c& is identical to
583 --- 4.2.22 2011/12/05
585 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
586 APDUs for a connection to a WRBUF.
588 --- 4.2.21 2011/11/23
590 Fix cql_sortby_to_sortkeys. Completely broken before.
592 Make CCL's @truncation work again.
594 --- 4.2.20 2011/11/09
596 New ZOOM connection setting: tproxy. It's like proxy, but does not
597 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
598 to set resolved address + port for a connection outside ZOOM itself.
600 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
602 --- 4.2.19 2011/11/07
604 Fix uninitialized variable in Solr spell support (could cause SEGV
605 for SRU response decoding).
607 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
608 back-end's addinfo through into the ZOOM response addinfo.
610 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
611 they are separated by a colon and a space rather than simply
614 --- 4.2.18 2011/10/28
616 Add support for Solr spell-checking/suggestions through ZOOM.
617 If a Solr target has been configured correctly for spelling-checking
618 and suggestions, these will now be returned on the ResultSet option
619 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
621 --- 4.2.17 2011/09/28
623 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
624 with a flag whether to substitute escape sequences or not.
626 --- 4.2.16 2011/09/22
628 Fix nmem_strsplit_escape to substitute escape char properly.
630 New option for zoomsh -e , which makes it abort on first error and
631 return process exit code to indicate success/failure.
633 YAZ options utility supports special option -- which makes all it treat
634 all following arguments as non-options.
636 --- 4.2.15 2011/09/16
638 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
639 searched if absolute filename is given.
641 Fix conv_xslt() error-reporting when stylesheet is not found.
642 (The value of fullpath is meaningless in this situation.)
644 --- 4.2.14 2011/09/07
646 Fix problem in CQL sort node creation: un-initialized memory.
648 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
649 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
650 CQL sortby depending on whether Type-1 or CQL is actually sent to the
653 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
654 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
656 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
657 will make it possible to use both single-character mask (#) and wildcard (?)
658 in CCL . Throw diagnostic for left truncation because that is not supported
661 --- 4.2.13 2011/09/01
663 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
664 cases using escapes (\-sequences) and masking.
666 PQF parse fix: A trailing backslash followed by end-of-string (\0)
667 would result in a read one byte beyond string.
669 rpn2ccl may use Z39.50 masking for terms (t=z).
671 ICU check fix. Don't include library -lCrun on Solaris, unless present.
673 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
674 not --cppflags (which seeems like an error in icu-config).
676 --- 4.2.12 2011/08/27 RPM package only
678 cql2ccl: fix conversion of terms: operator characters were not
681 --- 4.2.11 2011/08/25 RPM package only
683 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
684 CCL parser will map both # and ? to their regular expression
685 quivalents (. and .*).
687 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
688 of reserved CQL characters.
690 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
691 is, so that they are passed through.
693 --- 4.2.10 2011/08/24
695 ZOOM SRU mode: more aggressive re-connect.
697 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
698 made available as a utility function, declared in <yaz/logrpn.h>
700 rpn2cql_structure() supports proximity nodes (except that the Type-1
701 proximity node's "exclusion" binary is ignored, as there is no way to
702 express that in CQL). Fixes bug #4564.
706 Fix SEGV that could occur if set command of zoomsh was given without
707 value (2nd argument).
709 Fix SEGV that could occur if unsupported transport was given for
710 COMSTACK - say https (when SSL was unavailable).
712 Build yaz-url on Windows too.
716 New utility to get web content. Header is url.h. A command line tool
717 yaz-url is part of the distribution and packages.
719 Fixes for SSL COMSTACK (when gnutls is in use).
721 New functions yaz_base64{encode,decode}. Header is base64.h.
725 ZOOM C includes HTTP response buffer as additional info if it fails
726 to decode the SRU response.
728 Make wrbuf_json_puts available.
732 zoom: throw diagnostic for invalid value for option "sru". Before a
733 bad SRU request was sent.
735 Adding new utility wrbuf_vp_puts.
737 Add cclxmlconfig.obj to win/makefile. It was missing completely.
741 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
742 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
743 redirect was used at the same time.
745 MARC line mode decoding: be less picky about length given - first
746 5 digits of header that is.
748 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
750 Changes to decoding of SRU records: a record with recordPacking=xml is
751 modified with a new root element <yaz_record> if the recordData contains
752 multiple children elements. This is to make the record XML parseable
755 RPN to Solr conversion: encode special characters.
757 Generic Frontend Server: fix uinitialized member, stepSize.
761 Fix a bug in SRU decoding of records.. The database records stored
762 had un-initialized memory, but it would only be seen with yaz_record_render
763 and type_spec="ext" .
765 Fix a bug in ccl_qual_dup introduced in 4.2.3.
769 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
773 Add new utilities to convert from CQL to CCL . These utilities have
774 prefix cql_to_ccl defined in cql.h.
776 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
777 lead to memory heap corruptions when ICU utilities were in use.
781 Make compilation work without Libxml2.
783 yaz-client: remove redundant blanks in display of searchResult-1 term
788 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
789 resulting CQL node (tree) in a new node CQL_NODE_SORT.
791 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
792 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
793 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
794 Note that the CQL sortby spec is only converted when the GFS is already
795 converting from CQL to RPN (cql2rpn element).
797 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
798 specify whether to collapse delimitors or not. The existing nmem_strsplit
799 do collapse (collapse parameter = 1).
801 Windows installer: For NSIS, set InstallDir depending on x86/x64.
803 Rename internal func yaz_use_attribute_create. While non-static, this
804 function is not declared in a public header.
808 Add -lCrun when linking with ICU on Solaris.
810 More quicks character set conversions for OPAC records.
814 fix problem with record_render: records were converted (character set
815 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
819 SRU: add methods for handling DADS SRU-proxy facets.
821 Separate OPAC record character set for ZOOM_record. yaz_record_render
822 allows a character set given as charset=from/opacfrom,to where 'from' is
823 the character set of a bibliographic record, 'opacfrom' is character set
824 of OPAC record and 'to' is the target character set.
828 yaz-client: show may XML format records. Command show followed by 'format'
829 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
832 src/stemmer.c: Avoid using unnamed union. It is not supported by some
835 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
838 Update yaz.spec to operate on both SLES11 / Centos 5.5.
840 RPM: Release includes 'indexdata' name. Use indexdata in release name so
841 this package can be distinguished from other vendors.
843 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
844 as determined by configure
846 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
848 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
849 returns no error and no record, the present request is considered
850 partial (only a subset of the records could be returned by backend), and
851 so it is appropriate to set Present Status to partial-4.
855 Move yaz-config man pages to section 1.
857 More documentation about Solr.
859 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
860 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
861 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
862 peers on some Linux systems. However, in general that does not work
863 so YAZ can not rely on that to work. Debian changed behavior in this
864 respect from Debian lenny to Debian squeeze (still testing as of Oct
866 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
868 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
872 Fix yaz-config output: echo_source not set correctly by configure.
876 Solr Web Service support for yaz-client and ZOOM.
878 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
880 --- 4.0.12 2010/08/17
882 Z39.50 facet support. Facet specifications are passed for search in
883 other-information with ASN.1 as defined in facet.asn and OID
884 .10.1000.81.5 . Facets are expressed as an Attribute list as known
885 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
886 3 is limit (number of entries to get in response). yaz-ztest returns
887 dummy facets if a client asks for them.
889 --- 4.0.11 2010/07/09
891 CCL fixes: bug 2895 and bug 3539.
893 GR1-display: add comma in display - was removed by mistake in
896 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
898 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
900 --- 4.0.10 2010/06/18
902 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
903 result set from a connection. The result set will be on its own
904 thereafter; no operations on it will perform retrievals from a target.
905 Only cached copies are returned.
907 ZOOM C:fix case for HTTP servers responding with Connection:close.
908 Ensure that if there is a current task it is resumed (like fetching
909 more records in a result set) . Bug #3484.
911 PQF parser: use odr_atoi for Odr_int (not atoi)
913 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
914 values that contain any non-digits are treated as string attributes
915 (previously decoding only checked for leading character ([0-9]). PQF
916 encoding: attribute string values are not surrounded by double-quotes.
920 New utility for managing threads - thread_create.h.
922 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
923 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
924 but YAZ' implementation do.
926 Fixes for yaz_cond-functions on Windows 7.
928 DLL export more symbols.
930 zoomsh: show record do NOT render opac.
932 Remove *.la files from Debian and RPM packages.
936 Debian package libyaz-dev depends on libgnutls-dev again (was
937 removed in YAZ 4.0.6, but due to Libtool it is still needed
938 even though yaz-config do not list libgnutls libs).
940 ZOOM: Use only one WRBUF for returning string results for
941 ZOOM_resultset. Reduces memory usage for ZOOM in general.
943 ZOOM: ZOOM_connection do not use a shared pointer to
944 ZOOM_resultset after ZOOM_resultset is destructed by
945 user. Reverts to YAZ 4.0.4 behavior.
949 record-conv: fix problem with at least one XSL conversion -
950 due to probably incorrect usage of XML XSL documents.
954 Fix yaz-config for static mode and the use of SSL (gnutls).
958 Forward decl timeval struct in mutex.h and gettimeofday.h.
960 yaz-config: fix 'static' mode linking.
964 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
965 are wrappers for pthreads or Windows. For Windows these are put in
966 a separate DLL: yaz_cond4.
968 libyaz.la (whole source) is compiled with thread. If thread support
969 is enabled enabled, all source of YAZ is compiled with treading support.
970 This allows core utilities such as yaz_log to use thread facilities.
971 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
972 thread utilities. This commit moves mutex utilities (mutex.c) from
973 libyaz_server.la to libyaz.la.
975 yaz-json-parse displays leading text until error.
979 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
980 patch from Giannis Kosmas.
982 SRU: no longer URL encode SRU database. The URL for an SRU server is
983 a URL and such is alreeady encoded - at least when given with leading
984 http:// or https://. This reverts behavior to YAZ 3.0.50.
986 Support for new MARC XML notation TurboMARC which like MARCXML is a
987 complete representation of MARC/ISO2709.. This one, however, is more
988 compact and allows for faster processing with XSLT. TurboMARC can be
989 used in the marcdisp.h API, from the yaz-marcdump utility and from
992 yaz-ztest can be configured - via the database - to perform certain
993 delays when it performs operations search, present and single record
994 fetch. This allows testers to make yaz-ztest act as a real or even slow
995 Z39.50 server. Refer to the yaz-ztest man pages for details.
999 wrbuf_destroy allows NULL WRBUF passed to it.
1001 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1003 Add ZOOM_connection_close.
1005 No fixed size buffers for ZOOM shell - bug #3257.
1007 tstodr: make it work on s390 platform.
1009 New icu iterator-functions. The new icu_iter-functions makes it possible
1010 to use ICU chains from many threads.
1012 yaz-client: better syntax check for show command.
1014 --- 4.0.1 2010/01/26
1016 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1019 New simple local-file XML include facility which allows file glob-patterns.
1020 Refer to yaz/xml_include.h.
1022 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1025 ZOOM_record_get supports new parameter "format" which makes it format XML
1028 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1029 JSONText in ECMA-262) is JSONValue, not JSONObject.
1031 --- 4.0.0 2010/01/20
1033 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1034 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1036 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1037 POSIX/Unix builds .so with major version 4.
1039 Remove old LOG_-defines from log.h. They have been obsolete and
1040 undefined by default for the last 5 years.
1042 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1044 GFS: Remove socket (int *fd) from search_rr handler. The socket
1045 descriptor ptr is a facility that allowed a search handler to supply
1046 a socket which would serve as a callback - when search was complete.
1047 This facility has now been in use for years.
1049 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1050 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1051 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1052 returns 'const char *' rather than 'char *. The returned string is
1053 read-only and should not be modified by applications. COMSTACK cs_close is
1054 now a void function - it no longer returns int. No applications check for
1055 the value and the implementations has always returned 0.
1057 ZOOM: use size_t for scan hit counts and str size. Functions
1058 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1059 occ (hit count) and len (string length) are now of type size_t pointer
1060 rather than int pointer. This is to be able to represent large hit counts
1061 and to also just to use the proper type for string length (strlen result).
1063 New JSON parser. Refer to include/yaz/json.h .
1065 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1066 Used to be int in some cases. Many wrbuf_-functions used to return an int
1067 indicating some length.. These return values were never used. And so they
1070 ODR: odr_malloc, odr_total now takes size_t for size.
1072 clone_z_type: fix leak; occurred for encoding failures.
1074 --- 3.0.52 2009/12/03
1076 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1077 bug was introduced in 3.0.51.
1079 --- 3.0.51 2009/12/02
1081 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1083 tcpip comstack: fix leak for getaddrinfo.
1085 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1086 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1087 Decoding of SRU "path" database is performed by private function
1088 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1089 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1091 yaz-client: honor base command for SRU. Change when database setting
1092 is applied for SRU and ensure it is kept when a connection is reset.
1093 Change also the way errors are displayed or SRU (decoding of packages).
1095 --- 3.0.50 2009/11/02
1097 Add support for extra request / response data for SRU codecs and GFS.
1098 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1099 for extra data response buffer and length. For the GFS, both request
1100 and response data (XML) is carried in extra_args and extra_response_data
1101 for the search handler. Patch by Ko van der Sloot.
1103 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1104 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1105 10010). This fixes bug #2113.
1107 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1108 cmdfile included a 'quit' command that would result in a memory violation.
1110 --- 3.0.49 2009/10/01
1112 Make a number of functions defined in xmlquery.c static. These have
1113 never been declared in a public header file (yaz/xmlquery.h) and was
1114 made public by mistake.
1116 Improve speed of character conversions (iconv utilities). This makes
1117 conversions from MARC-8 faster.
1119 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1120 unless type desired is "raw". This will prevent type "xml" from
1121 returning ISO2709 .. Which obviously can not be XML parsed.
1123 Fix memory leak in ZOOM that would occur if option apdulog was used
1124 on a re-used connection.
1126 Frontend server logs HTTP requests.
1128 Frontend server now sends Z39.50 close when it times out (sesssion has
1129 been idle for too long). Versions 2.0.30 and earlier also sent close.
1130 But due to a mistake this was disabled in all versions after that, i.e.
1131 the server would just close the socket immediately.
1133 yaz-client emits a better message when receiving an unrecognised
1134 userInformationField.
1136 Skip zero-length subfields when decoding ISO2709. This rare case happens
1137 if a record has two FS characters in a sequence. Without this patch
1138 there would be a reference beyond char array in using_code_len fragments
1141 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1143 --- 3.0.48 2009/08/28
1145 The show command offered by the zoomsh command now takes a 3d optional
1146 parameter type which is what is passed to ZOOM_record. If the type
1147 argument is omitted, "render" is used.
1149 RPN to CQL conv may use USE string attributes (bug #2978).
1151 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1153 --- 3.0.47 2009/07/08
1155 Function yaz_xml2query allows a diagnostic element in the PQF XML
1156 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1157 code and additional info respectively.
1159 The BER BOOLEAN is now the integral type Odr_bool which still happens
1160 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1161 typedef'd to Odr_int. This is still an integral 'int', but it may be
1162 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1163 ASN-1 compiler as well as programs has been updated to use the new types.
1165 --- 3.0.46 2009/06/08
1167 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1168 only the bibliographic record was rendered. For type=opac, an OPAC
1169 record is only returned if it is present.
1171 iconv: small fix for encoding of advancegreek.
1173 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1175 yaz-client: option auto_reconnect=on really reconnects.
1177 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1179 server: avoid null ptr ref for for yaz_poll errors.
1181 build: fix RPM build for RHEL 5.3.
1183 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1185 --- 3.0.45 2009/03/31
1187 Fixed bug #2709: TCP connect returns Invalid argument.
1189 Fixed compilation for mingw.
1191 Honor charset for raw records (ZOOM_record_get).
1193 Fixed use of errno for threaded mode that was seen on Solaris 10.
1195 Fixed argument passing with blanks in value for Windows Service.
1197 Disable YAZ' own log rotate by default (no 1 GB limit).
1198 The variable l_max_size which specifies the log file limit is set to 0
1199 (DISABLED): This is due to the fact that YAZ is most often deployed using
1200 logrotate. Also YAZ can not perform log rotate because of unsufficient
1201 permissions (setuid).
1203 --- 3.0.44 2009/02/17
1205 List supported encodings in man page for yaz-iconv.
1207 Fixed missing SSL libs for --libs output
1209 Re-established OID record syntax application-xml. Nobody should use it
1210 but we don't want to change soname because of this symbol being absent.
1212 --- 3.0.42 2009/02/02
1214 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1216 Added member named_result_sets for init handler struct for the GFS. This
1217 allows a server to disable named result sets.
1219 Removed OID record syntax application-xml.
1221 Added support for rule-based transliterator for ICU wrapper of YAZ.
1223 Fixed bug #1902: yaz-icu XML output.
1225 Make YAZ checks Emacs friendly.
1227 BITSTRING value shows value. Bug #2346.
1229 ISO2709 decoding: skip control characters from indicator data.
1231 Omit sort key by default in yaz-icu's output.
1233 Allow combined single char options (again) for YAZ' options function.
1235 Utility yaz-marcdump got option to display YAZ version (-V).
1237 Allow YAZ to use ICU 3.4.
1239 Added new ICU test case which illustrates removal of diacritics.
1241 --- 3.0.41 2008/12/29
1243 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1245 --- 3.0.40 2008/12/29
1247 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1250 Fixed bug #2352: yaz-marcdump crashes for certain record.
1252 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1254 Added support for Danmarc2 to UTF-8 conversion.
1256 Added support for ISO5426 to UTF-8 conversion.
1258 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1259 implementation version.
1261 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1263 --- 3.0.38 2008/11/10
1265 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1266 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1268 ZOOM C now interprets databaseName option for ZOOM connection as path
1271 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1273 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1275 Dummy Libxml2 types no longer defined in headers of YAZ'.
1277 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1280 --- 3.0.36 2008/09/26
1282 Various ODR chapter fixes.
1284 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1286 Added missing source for Windows compilation, mutex.c.
1288 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1290 For SRU connections in ZOOM all records up to "count" are now fetched.
1292 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1293 in Windows due to bad error handling for Libxml2.
1295 Added facility for sending arbitrary records (ASN.1 any) using
1296 ZOOM C's Extended service update. Patch by Sam Reynolds.
1298 New options for ZOOM C's connection, logapdu which makes ZOOM log
1301 --- 3.0.34 2008/06/18
1303 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1305 --- 3.0.32 2008/06/12
1307 Fixed memory violation that could occur when decoding UTF-8. This bug
1308 was only present in 3.0.30 of YAZ.
1310 --- 3.0.30 2008/06/06
1312 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1313 GNU TLS is used by default (if found).
1315 yaz-ztest returns OPAC records if a client asks for OPAC.
1317 Improved speed of MARC-8 encoding.
1319 Added support for lossy and loss-less MARC-8 encoding.
1321 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1323 Added new Windows Service wrapper (sc).
1325 yaz-client's itemorder command may now send a file.
1327 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1329 Added new function yaz_log_xml_errors.
1331 Allow (but warn) unknown XML attributes in MARCXML parsing.
1333 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1335 The UTF-8 to MARC-8 conversion now uses a different set of characters
1336 for Greek symbols. Bug #2120.
1338 --- 3.0.26 2008/02/21
1340 Added yaz_daemon (daemon.h).
1342 Fixed bug #2068: pkg-config trouble
1344 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1346 --- 3.0.24 2008/01/28
1348 Document --with-xml2 option.
1350 Added OPAC XML XSD (etc/opacxml.xsd).
1352 Allow glob mask for name attribute in retrieval element for the
1353 generic frontend server's retrieval facility.
1355 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1356 except POLLIN/POLLOUT.
1358 Fixed error handling in cs_listen. Bug #2037.
1360 --- 3.0.22 2008/01/20
1362 Fixed version in yaz/yaz-version.h.
1364 Fixed bug #2027: Crash when closing connection.
1366 Changed configure so that ICU support is only enabled if only ICU
1367 and Libxml2 is available (because the ICU chain is XML based).
1369 --- 3.0.20 2008/01/15
1371 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1372 is built. Only this DLL depends on the ICU runtime.
1374 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1375 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1377 Changed license of CCL module to 'Revised BSD'. After consultation with
1378 remaining members of the original EUROPAGATE consortium, we are re-issuing
1379 the CCL module without a separate license. The software was developed by
1380 Index Data as part of a research project. The special license was included
1381 to help feed usage information back to the project consortium to support
1382 project evaluation. At this time, the project consortium has long-since
1383 disbanded, and the majority of the original principals have retired. At the
1384 same time, we have significantly modified the software during the following
1385 years, to the point where very practically no original code remains. To
1386 simplify re-use of the software, we have contacted those members of the
1387 consortium who could be reached, and agreed to re-issue the module as a
1388 proper part of the YAZ package.
1390 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1392 CQL closer to being version 1.2 compliant. CQL also allows free-form
1393 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1396 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1397 bug could make Extended services handling crash in the ZOOM layer. This
1398 bug was only present in YAZ 3.0.18.
1400 --- 3.0.18 2007/12/19
1402 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1405 yaz-marcdump reads and writes collection wrapped records.
1407 Handle OPAC for record conversion module.
1409 Fixes for ICU wrapper.
1411 Allow ICU libs to be controlled with --with-icu .
1413 --- 3.0.16 2007/11/12
1415 Added yaz_poll which is a wrapper for select/poll. When poll is available
1416 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1417 sockets to be in use.
1419 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1420 functionality through an XML based configuration (ICU chain). This system
1421 is useful for search facilities such as Pazpar2 and Zebra that needs to
1422 perform tokenization of indexed material. The ICU code in a separate
1423 library libyaz3_icu.a.
1425 Added HTTP tunnel facility for COMSTACK, bug #1752.
1426 This is a facility that allows a Web proxy, such as squid, to tunnel
1427 Z39.50 traffic. This facility is "transparent" to must applications
1428 using YAZ. It's enabled by using pseudo transport connect: followed by
1429 the proxy address, followed by command, then follwed by he regular
1430 "virtual" addresss. For example,
1431 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1433 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1435 --- 3.0.14 2007/09/21
1437 Fixed bad memory reference in ZOOM_record - cuased by member not being
1438 initialized. This was a problem only in YAZ 3.0.12.
1440 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1441 fields were not removed.
1443 Changed the way C code is generated from codetables.xml. Made a MARC-8
1444 conversion trie for each characterSet section rather than codeTable.
1445 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1446 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1448 --- 3.0.12 2007/09/12
1450 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1451 from ZOOM_record_error).
1453 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1455 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1457 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1459 Better SRW-to-Bib-1 diagnostic mapping.
1461 ZOOM C and yaz-client announces SRU version 1.2 by default.
1463 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1466 Fixed in yaz_sru_decode to allow other version than 1.1.
1468 --- 3.0.10 2007/08/22
1470 Added support for SRU scan for ZOOM.
1472 Added support for the use of the older versions or Extended Service
1473 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1474 set to the version , 1=first, 2=second, 3=third. The third version is
1475 what ZOOM C has used so far. And that, obviously, is the default.
1477 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1478 therefore in Zebra and in SimpleServer-based applications). The new
1479 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1480 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1481 which is passed into the back-end search callback function.
1483 Added support for HTTP Basic authentication in clients: the SRU/W
1484 codec encodes the username/password elements of the PDU structure
1485 appropriately, and these may be set using the "user" and "password"
1486 options in ZOOM-C applications (the same options that are used for
1487 Z39.50 authentication).
1489 --- 3.0.8 2007/06/25
1491 Fixed bug #1208: SSL appears to be broken in ZOOM.
1493 Fixed bug #1206: Libxml2 include path weirdness.
1495 Added oid_name_to_dotstring.
1497 Allow elementSetName to be specified for ZOOM C record update.
1499 Allow waitAction to be specified for ZOOM C based for Extended Services.
1501 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1502 syntax OID. Bug introduced in YAZ 3 series.
1504 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1506 --- 3.0.6 2007/06/06
1508 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1509 directory. yaz-client now reads commands from file given by option -f
1510 if specified; then tries to read .yazclientrc in current directory.
1511 Failing that, it reads .yazclientrc from user's home directory.
1513 Added support for correlationInfo Note and ID for Record Update via
1516 Added yaz-client command querycharset which specifies character set for
1517 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1518 (termListAndStartPoint).
1520 Charset ISO5428:1984 is an alias for ISO5428-1984.
1522 Implemented a way to perform scan in a result set using Z39.50. This
1523 is achieved by attaching the result set name in the characterInfo
1524 (type InternationalString) of OtherInformation in the Scan Request PDU.
1525 The result set is identified in the otherinformation by the new OID:
1526 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1527 This allows for scan in result set and faceted search . Zebra did some
1528 of this in the APT term using attribute type 8 and value being result
1529 set. Using the OtherInformation approach for this is cleaner and easier
1530 to work with in proxies and the like. This facility can be used in
1531 yaz-client using new command setscan which takes a result set as first
1532 argument, start position (APT) as second.
1534 Changed decoding of SRU XML packed records to deal with servers that
1535 have recordData with XML data with multiple root nodes. Also make
1536 comparison for recordPacking case insensitive. Again, one server
1537 returns "XML" where others return "xml".
1539 For SRU responses allow Content-Type application/xml as well as text/xml.
1541 --- 3.0.4 2007/05/21
1543 Fixed bug in character set conversion of BER strings. Bug introduced
1546 --- 3.0.2 2007/05/08
1548 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1550 For OID class, use oid_class consistently.
1552 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1555 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1556 character set for bibliographic information interchange". By Giannis Kosmas.
1558 Added documentation on new OID API.
1560 --- 3.0.0 2007/05/02
1562 Changes to generic frontend server interface: added new member
1563 'query_charset' for bend_initrequest structure. A backend init handler
1564 should set this member to its native character set for query terms.
1565 When defined, the frontend server logic will announce this character set
1566 to a client if the negotiationModel bit is set by the client. All server
1567 implementors are encouraged to specify this. If a backend server does not
1568 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1570 Added CCL utility to remove terms (stop words) from resulting RPN
1571 tree. This is handled by functions with prefix ccl_stop_words_ .
1573 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1574 terms in RPN queries.
1576 Clean-up the CCL API. Moved some internal structures from ccl.h to
1577 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1578 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1579 This is replaced by ccl_parser_find_str which takes a string instead.
1581 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1582 libyaz.la is the core of YAZ except the generic frontend server and
1583 does not depend on POSIX threads anymore. libyaz_server.la is the
1584 generic frontend server facilities and uses POSIX thread functionality
1585 if available. The libyaz.la no longer depends on POSIX threads because
1586 the number of global structures is limited. NMEM no longer re-uses blocks
1587 between threads ; it simply free's memory immediately but allocates in
1588 "large" chunks as usual. We don't expect any performance penalties
1589 because of this. The yaz_log system is still using a global log_level so
1590 caution must be taken when modifying it with yaz_log_init_.. +
1591 yaz_log_mask_str. This, however, should not cause any trouble because
1592 these functions are called during initialization of application code
1593 anyway. `yaz-config --libs server` returns libs for server applications;
1594 `yaz-config --libs` returns libs for non-server applications.
1596 New OID database - with public definitions in oid_db.h. Removed old OID
1597 database including the head oid.h and definitions such as enum oid_value
1598 and struct oident. The new OID database uses the same string names as
1599 before but the 'protocol' is gone. There are now only two representations
1600 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1601 converts from string to OID; functions with prefix yaz_oid_to_string
1602 converts the other way.
1604 Change to emit_term() in CQL-to-PQF query translation: when a term has
1605 the /regexp relation modifier, do not process it for leading and
1606 trailing "^" and "*", which have quite different meanings in regular
1609 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1610 write handlers no longer carries a 'last' parameter. This will make
1611 yaz_iconv flush "less" characters. A flush is performed by call to
1612 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1614 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1615 removed, because function yaz_query_to_wrbuf does the same.
1617 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1618 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1620 Deprecated MARC utility functions removed.
1622 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1625 Branch split: YAZ_2_1_55_branch
1627 --- 2.1.54 2007/03/16
1629 Fix to ZOOM-C so that transparent reconnection is properly handled on
1630 connections that are in asynchronous mode.
1632 Fixed compilation on OpenBSD 4.0.
1634 Large strings in GRS-1 records are now properly displayed in yaz-client.
1636 Added character conversion support for "advancegreek"; based on patch from
1639 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1640 sequence is met. Before the error was not set so it would be unknown.
1642 Adjust yaz-marcdump MARC reader so that it skips until record separator
1645 --- 2.1.52 2007/03/07
1647 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1648 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1649 fd_set structure used as a bitmask for the FDs to be selected on.
1651 Using ACX_PTHREAD macro to check for POSIX threads.
1653 Fixed have-vsnprintf check.
1655 --- 2.1.50 2007/02/23
1657 Fixes for configure on BSD. Bug #900.
1659 Added snprintf/vsnprintf wrappers for systems that don't have
1660 limits (heavens forbid).
1662 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1663 created before all previous tasks were completed and removed from the
1664 task queue, the new task could be removed by a mistake.
1666 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1668 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1670 Fixed bug #832: Problem with MARC/charset in yaz-client.
1672 Fixed bug #668: save command line history for yaz-client.
1674 Fixed bug #830: pkg-config support.
1676 --- 2.1.48 2007/01/23
1678 Extended ZOOM result set options with two options that may be read by
1679 a client: resultSetStatus and presentStatus with values as specified for
1681 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1683 Fixed bug #827: Using SSL fails on Debian etch.
1685 Fixed bug #826: Weird looking chars for set of MARC records.
1687 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1688 that is treated as an ItemOrder with itemRequest being an XML document
1689 external. The value of "doc" is the content.
1691 Extended the GFS search facility. New member of bend_search_rr
1692 'estimated_hit_count' signals that hits is known to be an estmate
1693 (higher or lower than real hit count). New member 'partial_resultset'
1694 signals that the search was partial (hit count is lower or equal than
1695 real hit count). For Z39.50, the information is stored in resultSetStatus
1696 member of SearchResponse APDU. For SRU, the information is signalled
1697 via SRU diagnostic 59: "Result set created with valid partial results
1700 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1702 --- 2.1.46 2007/01/13
1704 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1706 Added ZOOM_connection_peek_event.
1708 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1709 the following new functions:
1710 ZOOM_event_nonblock, ZOOM_connection_process,
1711 ZOOM_connection_get_{socket,mask,timeout},
1712 ZOOM_connection_fire_event_{timeout,socket}.
1713 The existing blocking event handler, ZOOM_event, is a wrapper for the
1714 + blocking ZOOM_event_sys_{poll,select}.
1716 Implemented function ccl_xml_config which parses XML version of CCL
1717 configuration (bug #798).
1719 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1721 Added timings utility (yaz/timing.h)
1723 --- 2.1.44 2007/01/03
1725 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1728 Fixed bug #779: Rotation of apdu.log fails.
1730 Fixed for character set conversions:
1731 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1732 Honor G1 set in MARC-8 decoding.
1734 --- 2.1.42 2006/12/17
1736 Fixed bug #775: char conversion does not handle Alternative UTF-8
1739 Implemented function yaz_marc_read_line which parses MARC line format
1740 records. There is a wealth of formats out there. So far, this function
1741 reads line records produced by yaz_marc_write_line.
1743 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1744 more generic and easier to remember(!) options: -i format and -o format
1745 which specifies input format and output format respectively - where
1746 format is one of "marc", "marcxml", "line", "marcxchange".
1748 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1749 does not print anything except warnings for records.
1751 For yaz-marcdump, added support for MARC split into files (-s) with a given
1754 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1755 spec, at http://www.loc.gov/standards/sru/record-update/
1756 This has changed the binary layout of the following structs:
1757 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1758 bend_update_rr . Patch by Ko van der Sloot.
1760 Added GFS utility function bend_assoc_is_alive which returns 1 if
1761 association is still alive (client is connected); 0 otherwise (client
1762 closed connection). This allows busy servers to stop working for
1765 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1766 been a separate piece of software. This version of ziffy has been modified
1767 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1769 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1771 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1772 Client code may now interrogate options such as "init_opt_sort" to
1773 find out whether the server claims to support various options.
1775 --- 2.1.40 2006/11/27
1777 Added utilities yaz_{set,get}_esn to set/get element set name from
1780 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1781 of YAZ and has been so since YAZ 2.1.10.
1783 Implemented ZOOM_record_error which returns error information for
1784 record (surrogate diagnostic).
1786 --- 2.1.38 2006/10/31
1788 Updates for SRU Update by Ko van der Sloot:
1789 1. Changed name from "operation" to "action"
1790 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1791 versions in the code, marked as 'backward compatible'.
1792 3. Added diagnostics for SRU Update.
1794 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1796 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1798 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1800 For GFS, fixed problem with SRU diagnostic 'First record position out of
1801 range' being issued for 0 hits.
1803 zoomtst10 part of Windows Build.
1805 --- 2.1.36 2006/10/13
1807 Implemented yaz_filepath_comp which splits a path into file path
1808 components (required by Zebra 2.0.3+).
1810 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1811 BSD inspired license until now so this should not have any real impact on
1812 anybody. See http://www.opensource.org/licenses/bsd-license.php
1814 Fixed bug #687: Missing log lines.
1816 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1819 Fixed bug #689: SRU diagnostics to be added.
1821 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1822 whether a connection is idle (no more work do do).
1824 --- 2.1.34 2006/10/04
1826 Change type of optval from long to int for invocation of setsockopt with
1827 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1829 Added support for specifying the max log file size for the Generic
1830 Frontend Server. The size is given with option -r.
1832 --- 2.1.32 2006/09/21
1834 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1836 --- 2.1.30 2006/09/17
1838 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1841 Fixed bug in Generic Frontend Server that could cause a server to stop
1842 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1844 For the generic frontend server, the maximum record size is used as maximum
1845 size of incoming packages (SRU + Z39.50). The value until was previously
1846 only used in Z39.50 Init negotiation and, later, in a session controlled
1847 sizes of records returned. This is controlled using -k option. It can be
1848 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1850 --- 2.1.28 2006/09/04
1852 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1855 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1857 New option for yaz-marcdump -lpos=value which allows setting a portion
1858 of MARC header to a certain value.
1860 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1862 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1863 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1865 --- 2.1.26 2006/08/15
1867 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1870 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1872 --- 2.1.24 2006/08/08
1874 Fixed MARC ISO2709 encoding routines to deal with character set
1877 Minor changes to GFS logging. Database included in search request log
1880 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1881 cached/multiple records.
1883 Shared libraries are built by default on Unix+configure.
1885 Changed cql2pqf transformation to use a different evaluation order. The
1886 new order is: always, relation, structure, position, truncation, index
1887 and relationModifier. Old order was: always, relation, relationModifier,
1888 structure, index, position, truncation. Note that the the latter ones
1889 override former ones for identical attributes.. The new scheme means that
1890 it is possible to override any existing attribute with a relationModifier.
1891 And also that it is possible to override everything for the index rule
1892 (except the ones listed in relationModifier). No order is perfect but this
1893 one, we believe, covers more real cases.. The "always" should have been
1894 called "default", since the attributes there can be overridden with all
1897 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1898 compilation phase, but also for yaz-config --cflags output. This allows
1899 us to have public headers with Libxml2 stuff in them . It should also,
1900 eventually, make Libxml2 checks redundant in packages using YAZ, such
1903 --- 2.1.22 2006/06/15
1905 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1906 stored in uri, message and details.. Previously diagnostics were stored
1907 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1908 compatibility.. but he's probably the only one affected, so.
1910 Added support for CCL, compiled on the client side, in ZOOM-C. This
1911 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1912 input; the resulting query objects can be used for for searching with
1913 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1915 YAZ' configure searches for OpenSSL by default.
1917 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1918 SL_CTX_use_certificate_file. See
1919 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1920 for more info. Thanks to Ko van der Sloot.
1922 --- 2.1.20 2006/06/02
1924 Bug #600: SRU GET, POST support for yaz-client. Introduced
1925 command 'sru' which selects method SOAP/GET/POST.
1927 Allow missingValueAction to be specified for the sortspec string -
1928 function yaz_sort_spec. By default, the missing value action is null.
1929 Use ! to specify "abort". Use = followed by stringvalue to specify default
1932 Ensured that Present-handler (if defined) is called in GFS before any call to
1933 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1934 searchRetrieve requests.
1936 Documentation for YAZ is now based on the Docbook XML/XSLT using
1937 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1938 is no longer depending on jade/openjade or docbook-to-man scripts.
1939 PDF is no longer part of the distribution - but can optionally be
1940 made using DSSSL/jadetex or FOP.
1942 Added retrieval handling support in Generic Frontend Server to support
1943 conversion between MARC/XML as well as XSLTtransforms. See
1944 etc/yazgfs.xml for an example.
1946 Added Authentication support to Generic Frontend Server in SRU
1947 mode. Authentication using HTTP Basic is supported, as is the use
1948 of 'x-username' and 'x-password' parameters in the request itself.
1950 Added support for a new character set MARC8s identical to MARC8 except
1951 that it converts combined characters to single Unicode characters in the
1952 Latin-1 range (when possible).
1954 --- 2.1.18 2006/04/24
1956 ASN.1 compiler 0.4: generates brief Doxygen file header for
1957 generated .h/.c files.
1959 Utility yaz_iconv now supports conversion to MARC-8.
1961 New facilities for the MARC module. The reading - and writing of
1962 content are separate methods for the yaz_marc_t handle. The following
1963 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1964 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1965 format). Write functions have prefix yaz_marc_write_.. The existing
1966 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1967 available. Removed support for OAI-MARC and simplexml (not the
1968 simplexml from PHP5).
1970 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1971 to be returned for this connection.
1973 --- 2.1.16 2006/03/31
1975 Allow multiple languages and charsets to be specified with
1976 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1977 negcharset iso-8859-1,utf-8
1979 Translation of proximity nodes from CQL into PQF now works.
1981 Moved to automake 1.8, 1.9.
1983 Added function yaz_log_set_handler which allows a log handler to be
1984 installed. This handler will be called for all log messages. Output
1985 to file is also produced; but that can be disabled by passing NULL
1986 fname to yaz_log_init_file.
1988 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1990 For SRW (including GFS), accept application/soap+xml as content-type
1993 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1994 produces NO stylesheet reference even if a default stylesheet is specified
1997 --- 2.1.14 2006/03/14
1999 Updated Windows package to include yazd.dll + yazd.lib for the
2000 Development component.
2002 If the environment variable YAZ_LOG is set, then it is used as a
2003 string indicating the default level of logging to use if not
2004 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2005 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2006 used as before. So, for example, to omit warnings from YAZ logging,
2007 export YAZ_LOG=-warn
2009 cql_transform() now map structure and other attributes before indexes,
2010 so that index-specific structures and other attributes can override
2011 defaults. So now a combination of mapping specifications such as:
2013 index.dc.date = 1=date-modified 4=5
2014 does the right thing.
2016 cql_transform() now also respects the "always" mapping specification,
2017 which establishes an initial set of attributes to be used for all
2018 terms except where overridden by more specific attributes associated
2019 with the index, relation or modifier.
2021 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2022 which mode to use; one of "post", "get" or "soap" (SRW, default).
2024 Fixes for yaz_iconv routines: changed trie-based character set conversions
2025 to use only non-negative values for bit fields due to Sun's C compiler not
2026 supporting negative values.
2028 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2029 sequences where not read correctly. Fix by Rustam Usmanov.
2031 Updated win/makefile to use options, settings which makes things
2032 compile with VS C 2005.
2034 --- 2.1.12 2006/02/01
2036 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2038 In ZOOM socket code, use select instead of poll on MacOSX.
2040 ZOOM-C now support client-side compilation of CQL into RPN that is
2041 sent to the server, enabling CQL to be used against all Z39.50
2042 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2043 ZOOM_query object, and submit it using ZOOM_connection_search().
2044 The CQL-to-RPN translation uses a configuration file, the name of
2045 which must be specified in the Connection's "cqlfile" option.
2047 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2048 function, which takes as its start-term parameter a ZOOM_query object
2049 (which may have had either CQL or RPN set into it).
2052 --- 2.1.10 2005/11/29
2054 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2055 GFS to support this as well. Backend handler, bend_srw_update, does the
2056 update work. Code contributed by Ko van der Sloot.
2058 Allow retrieval of Search Result-1 information in ZOOM by the use of
2059 options that are attached to a result set. ZOOM documentation updated
2062 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2063 UTF-8 conversion. Patch by Raj Patel.
2065 Added option -m to GFS to control formatting of timestamps in log file.
2067 Added 'exit' as synonym for 'quit' in yaz-client
2069 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2070 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2071 for the new members. Patch by Ko van der Sloot.
2073 Added support for SRU POST. It is supported for content-type
2074 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2076 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2077 Instead make the library libyaz.la multi-threaded. Threading as a whole
2078 can still be disabled by configure option --disable-threads. Previosly,
2079 with older GLIBCs there were problems with MT libs under Apache. This
2080 has now been fixed a long time ago.
2082 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2085 CQL module modified to be case insensitive for relations/indexes/operations.
2087 Fixed bug in CQL transform code: incorrect value relationModifieder
2090 Added 'show all' command for yaz-client which retrieves all results
2093 Added new yaz-client, xmles, which takes a (private) OID and
2094 a document to be sent as an extended service request.
2096 Describe new yaz-client commands wait_response and set_auto_wait.
2098 Increase TCP/IP listener backlog from 3 (which I am guessing was
2099 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2100 that the socket will queue as many incoming connections as it's able
2101 to handle ongoing connections. In other words, it will never now
2102 refuse a connection that it would be able to handle merely because
2103 it's not got around to accepting() enough of the pending connections
2104 yet. This is the behaviour anyway under Linux, where the listen()
2105 argument is ignored; but not under BSD and on systems such as
2106 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2107 YAZ-based servers should now be uniform across operating systems in
2110 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2111 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2112 This allows yaz-marcdump to read large MARC batches (>2 GB).
2114 Modified all YAZ source files - except the source which is auto-generated
2115 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2118 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2119 corresponding to the existing *_setl() function. These allow option
2120 values containing arbitrary valuues.
2122 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2123 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2124 except that it returns an indicator of whether or not the sort
2125 criterion was accepted (0 for OK, -1 for invalid).
2127 --- 2.1.8 2005/06/07
2129 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2130 MARC output rather than returning "new" buffer.
2132 yaz-client warns about unknown init options.
2134 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2136 --- 2.1.6 2005/05/24
2138 Added support for SRW sort in Generic Frontend Server. Patch
2139 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2140 sortKeys - or NULL if none is provided.
2142 Fixed bug #307: It was impossible to specify indefinite/no timeout
2143 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2146 Added support for multiple languages and charsets to be specified in
2147 ZOOM. Each charset/language is separated by a blank. If negotiation is
2148 in effect in init-response, Option
2149 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2150 Code based on patch by Vasiliy Osadchuk.
2152 Fixed bug #306: infinite recursion that occurred when calling
2153 yaz_log_level_init as the first call (before other log level or
2156 Fixed bug in scan handling in front end server: if preferred-Position-In-
2157 Response was non-present, a NULL pointer referece was performed.
2159 --- 2.1.4 2005/04/26
2161 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2162 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2163 now defined for all those error codes. So instead of putting 109 in
2164 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2165 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2167 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2170 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2172 Program yaz-client now exits and produces an error message if multiple
2173 Z39.50 servers are specified on the command line (none or one allowed
2176 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2179 --- 2.1.2 2005/03/16
2181 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2183 Fixed bug #272: Preserve spacing for CCL terms.
2185 --- 2.1.0 2005/03/14
2187 Added support for virtual hosts and multiple backend servers for
2188 the YAZ frontend server. The configution is XML based and
2189 support specificition of CQL to RPN mappings and explain information.
2190 See section "Virtual Hosts" in the YAZ manual.
2192 Extended OPAC display utility. OPAC display utility renders
2193 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2194 to supplement yaz_marc_decode_wrbuf.
2196 Fixed a bug in MARC decoder that could caused it to crash for some
2197 invalid MARC records. More diagnostics and warnings where added in
2198 XML output (warnings, etc are stored in comments).
2200 --- 2.0.34 2005/02/08
2202 Fixes for UNIX domain sockets. Bug #261.
2204 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2206 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2207 Added yaz_marc_subfield_str which defines subfield lead string which is
2208 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2209 yaz_marc_endline_str which defines end of fields string used in
2210 YAZ_MARC_LINE format. Default string is newline.
2212 Experimental support for MarcXChange. This format can be produced
2213 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2214 http://www.bs.dk/standards/MarcXchange.xsd
2216 Added yaz-client commands scansize that sets maximum number of
2217 entries to be returned by scan.
2219 --- 2.0.32 2005/01/11
2221 Added support for SRW scan in yaz-client and Generic Frontend Server.
2223 * Added whereInList member to SRW Scan Term.
2225 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2227 Fixed NMEM system to return aligned blocks on the smallest boundaries
2228 that are suitably aligned for all possible types on the particular
2229 architecture YAZ is being built for.
2231 --- 2.0.30 2005/01/04
2233 Fixed numerious warnings that was issued with newer versions of GCC.
2235 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2236 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2239 Make YAZ Generic Frontend Server slightly faster.
2241 Enhance (and reduce) logging for Generic Frontend Server.
2243 Revert YAZ log system so that it flushes every write operation
2244 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2246 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2247 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2248 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2249 will effectively disable old definitions.
2251 --- 2.0.28 2004/11/09
2253 Added yaz_log_time_format which specifies log format using
2256 Added yaz_log_module_level which returns mask for a module. Value
2257 is non-zero mask a if module is enabled; zero if disabled.
2259 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2260 in include/yaz/cql.h.
2262 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2264 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2266 Fixed bug #172: RPM builds does not enable SSL.
2268 Doxyfile.in part of dist. Doxyfile generated by configure.
2270 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2271 are given and the corresponding component does not exist.
2273 Extend CCL documentation in YAZ reference. Describe r=r.
2275 --- 2.0.26 2004/10/01
2277 Fixed MARC->MARCXML conversion to properly deal with
2278 fields, subfields, indicators having non-ASCII characters.
2280 Fixed MARC->MARCXML conversion so that ASCII control characters
2281 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2284 Added YAZ GFS support for conversion from Z39.50 surrogate
2285 diagnostics to SRW surrogate diagnostics.
2287 Bug fix: YAZ GFS did not return schema in explainResponse.
2289 --- 2.0.25 2004/09/30
2291 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2292 now converts recordSchema to elementSetName as well as schema URI.
2294 Fixed bug in COMSTACK that prevented HTTP request packages from being
2297 --- 2.0.24 2004/09/29
2299 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2300 does not require white-space before and after the dash in a range, e.g.
2301 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2304 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2305 due to new GCC removing "redundant" code.
2307 Added yaz-client commands scanpos and scanstep that sets preferred
2308 position and step-size for scan.
2310 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2312 Added CCL utility ccl_qual_buf which parses one or more CCL
2313 spec lines in a buffer.
2315 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2316 of name and value - ignoring empty lines and comments.
2318 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2320 Added odr_get_element_path which returns current element path for an
2321 ODR handle. This utility is useful in error handling or user-defined
2324 Added ODR_PRINT utility odr_set_stream which is is a more generic
2325 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2326 to a write function and pointer to close function. The close function - if
2327 non-NULL - will be called during odr_destroy.
2329 Fixed bug in CCL parser where truncation char was not removed from
2330 right side when truncation=both was in effect.
2332 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2335 --- 2.0.23 2004/08/11
2337 Fix buffer overrun in CQL parser when dealing with proximity (%).
2339 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2340 to UTF-8/UCS conversion is now only based on codetables.xml.
2342 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2344 --- 2.0.22 2004/08/06
2346 Add support for more "commit changes" in ZOOM (uses Extended Services).
2348 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2351 Yet another small fix for configure of SSL.
2353 --- 2.0.21 2004/05/14
2355 Fix SSL libs for configure when --with-openssl=DIR is given.
2357 --- 2.0.20 2004/05/10
2359 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2361 SSL comstack now uses yaz.pem certificate file on server side
2362 by default. Certificate filename can be configured by calling
2363 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2365 Fix bug regarding multiple calls to ZOOM_connection_connect.
2367 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2369 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2370 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2372 ZOOM now allows inspection of X509 peer certificate for verification.
2373 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2375 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2376 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2377 as "modular" but it simplifies things.
2379 Added cs_get_peer_certificate to that returns peer X509 PEM.
2381 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2382 NULL if SSL is unavailable.
2384 Documentation about MARC decoding tools.
2386 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2388 --- 2.0.19 2004/03/30
2390 Rename CHANGELOG to NEWS to follow GNU style packing.
2392 Fix bug with missing initialization of member in init_diagnostics.
2393 This bug affects threaded version of GFS server.
2395 --- 2.0.18 2004/03/20
2397 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2400 Ensure zlib.dll is packed with Windows install.
2402 --- 2.0.17 2004/03/17
2404 Fix encoding of xsd:string to use text instead of CDATA.
2406 Fix endless loop in CQL parser with unbalanced ".
2408 Use a more compact way to store MARC-8 conversion tables.
2410 --- 2.0.16 2004/03/16 Debian only
2412 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2415 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2420 --- 2.0.15 2004/03/01
2422 Another fix for decoding of XML packed records.
2424 --- 2.0.14 2004/02/25
2426 Fixes for Chunked encoding. White space not ignored after length spec.
2428 Update NS and use default NS for SRW diagnostic elements.
2430 --- 2.0.13 2004/02/23
2432 Implement ZOOM_resultset_cache_reset which resets record cache.
2434 Implement ZOOM_resultset_sort which sorts a result set.
2436 Implement chunked HTTP transfer.
2438 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2440 --- 2.0.12 2004/02/16
2442 Added member 'schema' to bend_explain_rr structure so that backend
2443 can specify explain record identifier. Defaults to Zeerex 2.0.
2445 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2447 --- 2.0.11 2004/02/16
2449 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2452 Added init command for yaz-client which sends "extra" init request.
2454 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2455 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2457 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2459 Make ZOOM error code for "invalid query".
2461 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2463 --- 2.0.10 2004/02/05
2465 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2468 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2470 Added option -p <file> to make Generic Frontend Server to write PID file.
2472 Added option -D to put Generic Frontend Server in background on its own.
2474 Make ZOOM C recognize option "password". If unset, "pass" is used
2475 (for backwards compatibility).
2477 Fixed a bug in Generic Frontend Server that could make it crash if a
2478 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2481 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2482 Must be issued before open, in order to be in effect.
2484 --- 2.0.9-6 2004/01/12 Debian/Windows
2486 Make the SRU server more picky WRT unknown params, etc.
2488 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2490 New YAZ client command, options, that sets Z39.50 options.
2492 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2493 options from a string of tokens (one token for each option bit).
2495 Update SRW diagnostic code messages.
2497 --- 2.0.9-5 2004/01/07 Debian/Windows
2499 Handle user defined stylesheet for SRW/SRU.
2501 --- 2.0.9-4 2004/01/06 Debian/Windows
2503 Fix bug in decoding of Content-Length.
2505 --- 2.0.9-3 2004/01/06 Debian/Windows
2507 Fix a bug with decoding of XML packed records.
2509 --- 2.0.9-2 2004/01/05 Debian only
2511 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2513 Fix bug in SRW/SRU diagnostics decoding.
2515 --- 2.0.9 2004/01/05
2517 Fixed bug in Generic Frontend Server which could drop records exceeding
2518 preferred message size. Reported and fixed by Irina Dijour.
2520 Fixed calculation of package size for structured records in Generic
2521 Frontend Server. Reported and fixed by Irina Dijour.
2523 Fixed namespace for SRW/SRU diagnostics.
2525 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2527 --- 2.0.8 2003/12/22
2529 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2530 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2533 CQL changes to reflect recent changes to the specification:
2534 * Documentation talks about context sets instead of index sets.
2535 * Documentation talks about indexes instead of qualifiers.
2536 * The CQL-to-PQF transformer's configuration file now uses
2537 "index.set.name = <attributes>" instead of the old form
2538 "qualifier.set.name = <attributes>". (Both forms are still
2539 understood but the latter is deprecated.)
2540 * CQL terms with no explicit index specified are now interpreted as
2541 cql.serverChoice instead of srw.serverChoice (which of course
2542 behaves exactly the same.)
2544 --- 2.0.7 2003/12/16
2546 MARC conversion can now generate ISO2709 output in another
2547 character set. yaz-marcdump uses this facility if you invoke it
2550 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2551 functions from there can be used from C++.
2553 --- 2.0.6 2003/12/04
2555 Frontend server now transfers memory from decoded packages to stream
2558 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2559 references to show up.
2561 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2562 the ZOOM Abstract API. The older names for the same options are still
2563 also supported for the benefit of old applications.
2565 ZOOM-C supports "implementationId" and "implementationVersion" options
2566 to go along with "implementationName". These allow the user code to
2567 specify identification strings to be sent to servers.
2568 Add OID for the new ExtLite attribute set.
2570 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2571 as requested/supplid by Ere Maijala <ere@atp.fi>
2573 For generic frontend server, reverse the order of
2574 "toolkit-supplied / application-supplied" strings sent as implementationId,
2575 Name and Version. Also, remove the spaces around the slash. This brings
2576 the GFS in line with the behaviour of ZOOM-C on the client side.
2578 Add function ZOOM_scanset_display_term.
2580 yaz-client shows scan displayTerm if present.
2582 Utility yaz-iconv is now installed by default along with the man page
2585 Extend configure check for OpenSSL to use pkg-config where available (such
2588 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2589 server to specify uid/gid/mask for socket using the format
2590 unix:[user=uid,][group=gid,][umask=mask,]file=path
2591 If file= is omitted the existing format is assumed, e.g.
2593 in which case the mask is 0666 (rw for everybody).
2595 Major restructure of YAZ source. All source in libyaz is in src directory.
2596 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2597 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2599 Added man page for utility yaz-marcdump (used to be called marcdump).
2600 yaz-marcdump is installed by 'make install'.
2602 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2603 of incoming package failed.
2605 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2607 Change prototype of odr_perror: add const to message string.
2609 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2611 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2612 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2613 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2614 DNS lookup. There should not be any compatibility problems with this
2615 assuming that blocking=1 or 0 is used.
2617 Fix bad reference in UNIX comstack in function cs_addrstr.
2619 Fix for compilation on AIX.
2621 The generic front-end server (server/seshigh.c) now supports returning
2622 Init diagnostics to the client in User-information-field, in
2623 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2626 --- 2.0.4 2003/09/04
2628 Allow any CQL relation (not just all,any,exact,scr).
2630 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2631 that features the same UI.
2633 Implemented command update0 in YAZ client which is equivalent to
2634 update but uses old of Ext Update ASN.1.
2636 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2637 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2638 Previously no OID was used for this info.
2640 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2641 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2642 returns 'malformed search term' otherwise.
2644 SortResponse member resultCount now set to NULL in sort handler of
2647 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2650 Add three new utility functions for translating OIDs between various
2651 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2652 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2653 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2654 char *oid_to_dotstring(const int *oid, char *oidbuf);
2655 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2657 Reverted modifications for ES Update definition for z_IU0Update
2658 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2659 is back to YAZ 2.0.2.
2661 String value attributes for CCL parser.
2663 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2664 which their FirstSearch server returns in Init responses, sometimes
2665 carrying useful diagnostic information when Init fails. This has the
2666 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2667 "z39.50/oclcui.asn", where its definition is somewhat different from
2668 what OCLC document on their web-site, as required to interoperate with
2671 Support for anonymous authentication in yaz-client. Use the command
2674 * Fix the OID of the Index Data-local "admin" Extended Service from
2675 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2676 the 1000, which indicates a locally-defined OID, was a mistake.
2678 --- 2.0.3 2003/06/20
2680 Fix CCL directive @case handling so that it affects string match for
2681 both CCL keywords and qualifiers.
2683 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2684 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2685 Decoder has been updated with ASN.1 changes as listed in
2686 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2687 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2688 z_IUUpdate, remains unchanged.
2690 ZOOM_record_get may now return a record in a specific character set.
2691 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2692 "from" is the character set of record as returned by target. "to" is
2693 the character set to be returned. If omitted, "to" is UTF-8.
2695 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2697 New ODR utility, odr_getelement, which returns name of element for
2698 which encoding/decoding failed.
2700 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2701 in cases where a required element was omitted.
2703 Bug fix: some MARC8 sequences were not converted.
2705 New ZOOM option "step" which specifies number of records to be
2706 retrieved in one chunk. Used in conjunction with "start" and "count".
2708 SRW support for yaz-client. Use scheme http: to use it, e.g.
2711 yaz-client no longer does (un)intelligent character set conversions
2712 by default. Can be enabled with charset and marc_charset commands.
2714 xmalloc trace fix for 64-bit systems such as DEC alpha.
2716 Solaris 2.6 compile fix.
2718 New function, cql_strerror() translates SRW error codes, as returned
2719 by cql_transform_error(), into human-readable English strings. Used
2720 in yaz-client diagnostics when appropriate.
2722 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2723 converts it into a type-1 query which is sent to the server. This
2724 makes CQL available for use with all Z-servers, as opposed to the tiny
2725 minority that can handle CQL queries themselves.
2727 --- 2.0.2 2003/04/28
2729 New Debian package layout similar to the Redhat Package layout.
2731 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2732 and search result respectively.
2734 --- 2.0.1 2003/04/25
2736 Redhat package is now several packages: libyaz (runtime libraries),
2737 libyaz-devel (development and documentation, and yaz (utility programs).
2738 Package spec file by Morten Bogeskov.
2740 New member 'schema' in struct bend_fetch_rr which the name of requested
2741 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2742 handler MAY set this to reflect the schema of the returned record.
2744 New member 'display_term' in struct scan_entry. GFS now sets member entries
2745 and allocates scan entries to be filled by user scan handler. In previous
2746 version, entries member was allocated by the scan handler. That still works,
2747 but the GFS will ignore member display_term - assuming it was NOT set by
2748 the handler. The fact that the GFS now allocates the entries both allows
2749 for new members and makes a scan handler easier to write.
2751 Fix CQL lex buffer overflow.
2753 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2754 SRU default recordPacking is string.
2756 SRU protocol support for frontend server.
2758 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2760 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2762 Added scan for the ZOOM shell (zoomsh).
2766 * String Identifers for Schemas (Amendment 5).
2767 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2768 Old definition for schema
2769 Odr_oid *schema; /* OPT */
2774 Z_InternationalString *uri;
2775 #define Z_Schema_oid 1
2776 #define Z_Schema_uri 2
2779 * resultCount parameter to Sort Response (Amendment 1).
2780 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2782 Support for SRW 1.0 over HTTP. This is an optional feature and
2783 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2786 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2787 on the same port. SRW SearchRetrieveRequests are mapped
2788 to bend_init,bend_search,bend_fetch,bend_close.
2790 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2792 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2793 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2795 ZOOM connections are SRW based if schem http is used for hostname
2796 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2797 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2799 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2800 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2801 distance=n, order=true/false, relation=le, prox unit=word. If
2802 n is omitted, distance 1 is used.
2804 Fixed problem with C compiler include path in wrong order.
2806 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2807 on Solaris. Patch from Ko van der Sloot.
2809 New MARC decode API. All new functions operate on a yaz_marc_t
2810 handle. The most important new functions are: yaz_marc_create,
2811 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2812 decode and destroy respectively. Decoder can produce formats
2813 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2814 include/yaz/marcdisp.h.
2816 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2817 to UTF-8, UCS-32, wchar_t or Latin-1.
2819 * Prototypes for yaz_iconv_-functions moved to separate header
2820 include/yaz/yaz-iconv.h.
2822 Make a few private functions 'static' in unix.c. This prevents
2823 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2825 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2826 are set when Init Response is received.
2828 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2829 but returns diagnostic set as well.
2831 New function yaz_strerror which is a portable wrapper for
2832 strerror/strerror_r/GetLastMessage.
2834 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2835 is returned for MARC. If type is "oai", then OAI MARC is returned.
2837 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2840 --- 1.9.2 2002/11/26
2842 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2844 Fix bad race conditions on SIGTERM and terminate gracefully in
2847 Move retrieval (data1) module to Zebra since nobody seems to be
2850 Add GRS-1 render for ZOOM using same format as yaz-client.
2852 --- 1.9.1 2002/10/05
2854 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2856 Fix broken ESpec handling in data1 module.
2858 SGML reader parses comments and makes them part of the data1 tree.
2860 Added several type casts so that YAZ compiles as C++ code.
2862 ZOOM didn't handle PDU encoding failures properly.
2864 Added more Bib-1 diagnostics (approved extensions).
2866 GNU configure: better check for iconv.
2868 More portable use of accept, getpeername. Check for socklen_t. Use
2869 int/size_t if socklen_t is not defined.
2873 PQF parser rejects bad queries - including those with extra
2874 characters in them. PQF parser used to silently ignore that.
2875 Cleaner API for PQF added, which allows you to get detailed
2876 error information for bad queries (see yaz/pquery.h).
2878 Fixed bug in ZOOM_record_get for type "database".
2880 Implemented mini iconv library supporting conversions between
2881 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2883 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2885 --- 1.8.9 2002/08/20
2887 Fixed ZOOM C record cache so that preferredRecordSyntax and
2888 elementSetName is used to check for already fetched records.
2890 --- 1.8.8 2002/08/02
2892 Added three members in bend_initrequest structure to facilitate
2893 character set negotiation.
2895 Fixed a bug in frontend server that could cause indefinite
2896 loops under rare conditions.
2898 Revised character set utilities (charneg.h) so that encoding
2899 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2901 For PQF, directive @term <type> sets term type for Scan/Search.
2902 Here <type> is general, string, numeric, null. The term type
2903 is inherited - just like @attr.
2905 New call odr_set_charset that sets character set conversion for
2906 international-strings on a ODR stream. Prototype is:
2907 int odr_set_charset(ODR o, const char *to, const char *from);
2908 The InternationalString is still represented as C string in YAZ
2909 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2910 won't). On the protocol level, you can use any encoding.
2912 Support for UNIX sockets in ZOOM.
2914 Solaris recv sometimes returns errno == ENOENT. It is treated as
2915 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2917 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2918 both client and server. Code by Morten Bogeskov.
2920 --- 1.8.7 2002/05/22
2922 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2923 that they can be used directly from Visual Basic. You must recompile
2924 your windows APP if you're using ZOOM.
2926 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2927 Commands "lang" and "charset" sets language and character set respectively.
2928 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2929 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2931 Attributes from multiple CCL fields may be OR'ed rather than merged
2932 using directive "@field or". Fields are still merged by default -
2933 equivalent to "@field merge".
2935 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2938 Fixed bug in zget for parameter ExtendedServicesResponse.
2942 --- 1.8.6 2002/03/25
2944 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2946 Client displays USR.1:SearchResult-1 (hits per term).
2948 Additional Search Info for search in Generic Frontend Server.
2950 Fixed CCL parsing of "field=s".
2952 WIN32 installer - using the excellent NSIS software from nullsoft.
2954 Fixed CCL parsing of "field = - <number>".
2956 Added function yaz_marc_decode that decodes MARC for line mode
2957 display or XML (similar to that used by JZKit).
2959 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2960 Z39.50. But ISO/ILL was, however.
2962 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2963 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2965 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2966 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2968 --- 1.8.5 2002/02/03
2970 New YAZ client features: Command completion and new commands:
2971 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2972 Code provided by Jacob Poulsen.
2974 New call oid_trav, that visits all registered OIDs via callback.
2976 Function ZOOM_record_get now returns const char pointer rather than
2977 void pointer. It saves a lot of type casts.
2979 For YAZ client, command "auth" now allows you to set authentication
2980 in IdPass style. It is enabled when three tokens are given - order
2981 is user, group and password.
2983 Fix memory leaks in MARC record handling for ZOOM.
2985 New option for YAZ client, -k <kilobytes> that sets
2986 maximum record size. Similar to -k option for generic frontend
2987 server and yaz-ztest.
2989 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2991 Prefix query parser reports "fail" when bad attribute set is given.
2993 Fix in MARC decoder. Proximity logging. Fix for attribute set
2994 in scan handler for server. Patches by Shigeru Ishida.
2996 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2999 Configure option --with-openssl=<dir> now works when a directory is
3000 specified. Patch provided by Morten Bogeskov.
3002 New option for YAZ client, -u <auth>, that sets authentication.
3004 ZOOM fix: error information was sometimes "missing", since error
3005 was cleared/reset too when it shouldn't.
3007 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3009 --- 1.8.4 2002/01/04
3011 Scan for ZOOM API. New object ZOOM_scanset. New functions
3012 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3013 ZOOM_scanset_destroy.
3015 New ZOOM function, ZOOM_connection_last_event, that returns type
3016 of last event (such as "receive data", "send data", "apdu received",
3019 New ZOOM option, schema, that specifies schema for retrieval.
3021 New CCL feature. Qualifiers can be aliases for one or more
3022 other qualifiers (if more than one is given, OR is used).
3024 ZOOM uses named result sets if target supports it.
3026 Two new YAZ client commands: . (dot, which sources a script of YAZ
3027 client commands), and ! (to execute shell command.). Implemented
3030 Working on Debian packages.
3032 --- 1.8.3 2001/11/19
3034 YAZ client enables named result sets only if target supports it.
3036 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3038 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3039 with key="host" to get same result.
3041 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3042 Function Z3950_resultset_record(s) returns references to records
3043 "owned" by resultset. To become owner use Z3950_record_clone.
3045 Function z_ext_record handles Extended Services. Thanks to
3048 --- 1.8.2 2001/11/12
3050 CCL Parser fix: ignore token comma when dealing with and-lists.
3052 Documentation updates for COMSTACK.
3054 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3055 Changed prototype Z3950_records. For some functions, int parameters
3056 were changed to size_t.
3058 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3061 New MARC decode/display function, marc_display_exl, which properly rejects
3062 non-ISO2709 records. YAZ client uses it.
3064 --- 1.8.1 2001/10/29
3066 Fix bug: local attribute set wasn't set correctly in PQF strings.
3070 * Old Z39.50 codecs no longer supported.
3072 Added ZOOM C binding. See http://zoom.z3950.org/
3074 Renamed states for COMSTACKs to avoid confusion with events.
3076 Implemented cs_look and proper cs_rcvconnect.
3078 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3080 Configure detects POSIX threads on OpenBSD.
3082 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3083 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3085 When error is returned from present handler, non-surrogate diagnostic
3086 is returned in present response (and fetch handler is no longer called).
3088 * Minor adjustments to pquery parser (PQF). Token characters may be
3089 escaped by using backslash (C-style).
3091 PQF parser allows string attribute values to be specified. For @attr,
3092 non-numeric characters after the equal-sign are treated as strings
3093 (e.g. @attr 9=title).
3095 CCL trunction character may be defined (@truncation in file)
3097 * function zget_ExtendedServicesRequest sets waitAction to
3098 waitIfPossible (was wait).
3100 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3103 CCL operator names may be set in field definition files (CCL_bibset).
3104 See ccl/bib1 for an example.
3106 Fixes in ASN.1 compiler for C++ compatibility.
3108 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3109 and "op_or" to avoid conflict with C++.
3111 Fixed problem with GNU readline detection on Redhat 7.0.
3113 Added step-size for Scan backend handler.
3115 Fixed bug that made the frontend server crash when no attribute
3116 set was specified for scan.
3118 Front-end server automatically switches to original working directory
3119 when installed as an NT service. Previously -w had to be specified to
3122 Added extended attributes for retrieval module (data1), so that data1
3123 records carry d1_readXML/SGML attributes. d1_read also supports
3124 null-data rules ( <tag/>)
3126 On UNIX when POSIX threads are available, a separate library libyazthread
3127 is created. Programmers should link with that library and the yaz library
3128 when using threads. The reason for the split was that some applications
3129 on Linux, such as Apache, doesn't work well when using shared objects that
3132 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3133 (or any frontend server) in SSL mode by specifying ssl: followed by
3134 address. Only tested on UNIX.
3136 Added feature for CCL module. Virtual structure s=al or s=ol generates
3137 and-list and or-list respectively instead of phrase search.
3141 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3142 log_mask_str. This was done to avoid name conflicts with other libraries
3143 (such as other PHP extensions).
3145 Added raw OID member for preferred record syntax (request_format_raw)
3146 and returned record syntax (output_format_raw) for backend fetch method.
3148 Config file yaz-config now accepts options so that it returns specific
3149 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3151 Shared library support for UNIX using GNU libtool.
3153 * Modified backend interface. Request/Response struct's replaced by
3154 one read/write C struct. For example bend_fetchrequest and
3155 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3156 Every handler - even search has to be registered in bend_init
3157 handler. This means that the YAZ library no longer refers to
3158 external functions and it makes it possible to make the whole
3159 thing a single DLL/SO.
3161 Added Segment handler for backend server.
3163 Added Zmbol/Zebra administrative functions to YAZ client.
3165 Threaded frontend server on UNIX (when POSIX Threads are available).
3166 Starting the server with option -T enables multi-threading.
3170 Added configure option --enable-comp/disable-comp to control use
3171 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3172 located in sub directory asn.
3174 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3175 in ${exec_prefix}/bin along with the other programs yaz-client and
3178 GNU automake used to maintain makefiles.
3180 Added several OID's.
3182 Changed retrieval module so that we can load records with no abstract
3183 syntax defined. Tagpaths in these records are fully composed of string
3186 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3190 On UNIX, the generated makefile now supports a proper 'make install'.
3191 The prefix can be set via GNU configure to set the install location
3192 (default is /usr/local).
3194 * YAZ programs client and ztest were renamed to yaz-client and
3195 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3196 locations, such as /usr/bin,/usr/local/bin,etc.
3198 * YAZ Header files were moved from include to include/yaz. YAZ Header
3199 files are referred to as include <yaz/log.h> rather than <log.h>.
3200 The YAZ include path (-I ..) is therefore the same as before. Programmers
3201 should update their #include statements or use -Ipath/include/yaz
3202 instead. The main motivation for doing this change is that YAZ header files
3203 can be installed in "standard" locations /usr/include,/usr/local/include
3204 without introducing conflicts, since ALL YAZ header files are stored
3205 in subdirectory yaz (under /usr/include for example).
3207 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3208 rather than project/workspace files. We switched because project files
3209 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3212 Changed name of logging function, logf, to yaz_log, to prevent name
3213 clash with some math-log functions. The YAZ header log.h defines logf
3214 to yaz_log (#define) so there should be no incompatibilities by this
3217 Added bend_start/bend_stop handlers for server. These handler are
3218 called on start/stop of server. For windows they are called whenever
3219 a service is started/stopped.
3221 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3222 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3223 in util/yc.tcl. The auto-generated C code structures are, in a few
3224 cases, incompatible with the old decoders. There are differences in the
3225 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3226 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3227 The preprocessor variable ASN_COMPILED is defined when the compiled
3228 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3229 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3230 wish to use the old encoders/decoders you can specify --disable-yc
3233 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3234 version so that it supports both new - and old version of DB Update
3236 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3237 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3238 change. The name parameter can be set to 0 in which no name is specified
3239 for the construction. The macros odr_implicit and odr_explicit sets name
3240 parameter to zero for the construction involved. New macros
3241 odr_implicit_tag and odr_explicit_tag are similar to the others,
3242 except that a name parameter is added. For programmers' that don't use
3243 ODR they probably only need to change the call to z_APDU and z_External.
3245 Added access control facility by interfacing the TCP wrapper library.
3246 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3247 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3248 name of the daemon and enables the access control as specified in
3249 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3251 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3252 den Dool <H.M.vdnDool@kub.nl>.
3254 Added reference ID parameter to most functions in server API - refer
3255 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3257 Changed name of ccl library to libccl.a (was ccl.a).
3259 Fixed bug in decoder for Explain (Category TargetInfo).
3261 Added support for GNU readline in client. Thanks to Jacob Poulsen
3262 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3264 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3265 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3266 IMPLEMENTATION! This change was made to the development version before
3267 the ZIG decided to retract the amendment. If any users MUST be
3268 compatible with the original Update definition, PLEASE CONTACT US, and
3269 we will include a separate definition corresponding to the old Update
3270 ES. Note that because of the change to the ASN.1 of the
3271 TaskPackageRecordStructure we cannot define a single structure that
3272 will support both versions.
3274 * Added const modifier to buffer parameter for some ODR/BER encoding
3275 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3276 completeWAIS, odr_dumpBER.
3278 Fixed bug in client.c which caused a crash when a scanResponse didn't
3279 contain positionOfTerm.
3281 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3282 * will cause an error in a client if a non-YAZ target sends both a
3283 * list of Scan entries and non-surrogate diagnostics.
3285 Retrieval module enhancements. Tag sets may be typed in the reference
3286 to it. From the .abs-file the "tagset" directive takes a third optional
3287 integer type for the tag set referenced. From a .tag-file the "include"
3288 directive takes a third optional type as well. The old "type" directive
3289 in the tag set itself is still recognized but acts as the default type
3292 Backend interface change. Individual Scan terms returned from bend_scan
3293 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3294 in include/backend.h.
3296 Retrieval module enhancements. Multiple tag sets and attribute sets may
3297 be specified in abstract syntax specs. Revised the error/warning for
3298 logging messages reported by the retrieval module when reading the
3301 Object Identifier system (oid_..) changed. The API is backwards
3302 compatible but the oid-routines now allocates new OID's when needed.
3303 Raw OID's may be specified in oid_getvalbyname.
3305 YAZ now uses GNU configure to generate Makefile(s).
3307 * Minor changes in some of the member names of DeleteResultSetRequest and
3308 DeleteResultSetResponse. See include/proto.h.
3310 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3311 and added member 'languages' in TargetInfo (which was missing).
3313 Changed the way attribute sets are handled in the retrieval
3314 module. These are now cached, just like the abstract syntaxes
3317 Changed YAZ so that it links with compiled ASN.1.
3319 Added Explain-schema definitions and mapping routines. The following
3320 Explain categories have been implemented: AttributeDetails,
3321 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3323 Fixed minor bug in Windows version of Server Library.
3325 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3327 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3329 Added EXTERNAL: UNIverse Resource Report (non-standard).
3331 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3332 ENUMERATED and SET OF.
3334 * Added 'const' to some of the char pointer arguments for the
3335 functions, data1_read_node, data1_getelementbytagname,
3336 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3339 Fixed bug in data1_insert_taggeddata - the last_child member of
3340 parent wasn't initialised.
3342 * Changed data1_read_record and data1_read_node so that the supplied
3343 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3344 doesn't refer to any parts of the "SGML"-buffer.
3346 Fixed bug in server library (Windows version of statserv_remove).
3348 * Changed code so that it compiles as C++. The type definition
3349 of Odr_fun which is a member of Odr_arm was changed. The result is,
3350 that an explicit typecast is needed for the fun pointer when
3351 using Odr_arm - as in:
3352 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3354 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3356 Implemented the new structured date and time definition as approved
3357 by the ZIG. Added schemaId element to the specificTag in Espec-1
3358 (also approved at the last ZIG). Thanks to RVDM.
3360 Added some Object identifiers (RVDM).
3362 Changed the Update Extended Service (RVDM).
3364 Added command "refid" to client which specifies referenceId for
3365 the following requests.
3367 Implemented extended service handling for server. See ztest.c
3368 for an example as well as backend.h. New handlers are registerd
3369 in the Init handler.
3371 * Changed interface for sort in server.
3373 Added new members to statserv_options_block. It allows a server
3374 to read options from another source than just the command line. Thanks
3375 to Charles Woodfield.
3377 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3378 renamed to zboolean. Some C++ compilers complained about the name.
3380 Minor changes to gils.abs. Added index 's' (sort) on title
3381 and date/time-last-modified.
3383 --- 1.4pl2 1998/1/30
3385 Fixed bug in server library regarding inetd mode (-i). This bug
3386 was introduced by release 1.4.
3388 --- 1.4pl1 1998/1/29
3390 Added sort facility in client and backend server interface.
3392 Fixed problem with dependencies in Makefile(s).
3394 Fixed bugs for encoders/decoders of extended services and
3397 Implemented sub-tree feature for schemas. Sub-trees are
3398 referenced in *.abs-files. See explain.abs for an example
3399 of the use of this feature.
3401 Modified bib1.att; local attributes for ANY didn't include
3402 ANY itself (only affects use of the retrieval module).
3404 Fixed bug in plain SGML reader in function data1_read_node:
3405 tags with prefix "var" was incorrectly interpreted as variants.
3407 Added feature "sub-schemas" to enable references to - and definitions
3408 of - group of elements.
3410 * Removed member parent from type data1_element (in data1.h).
3412 Implemented function odr_nullval() that returns the value of
3415 * Removed member num_children from data1_node (in data1.h).
3417 Made NT service interface part of the server library. The
3418 function statserv_main uses the NT service when required and
3419 calls the statserv_start / statserv_close routines.
3421 Routine zget_SearchRequest and zget_PresentRequest fills
3422 resultSetName/Id member with "default" instead of "Default".
3424 Fixed memory leak in server. Request queue member wasn't freed.
3426 Fixed nmem_exit so that memory is freed.
3430 Revised the CCL parser utility to be thread safe.
3432 Added function, oid_ent_to_oid, to replace the function
3433 oid_getoidbyent, which is not thread safe.
3435 * Added nmem_init and nmem_exit to initialize and release
3436 NMEM resources. Function nmem_init should be called once in the
3437 initial thread before NMEM/ODR is used. statserv.c and client.c
3438 have been changed accordingly. The change was necessary to make
3439 NMEM thread safe. The NMEM memory pool is shared amongst threads
3440 in a process. Unix-based applications will still work fine without
3443 Added NT Services interface for the the Z39.50 (statserv) Server.
3444 Refer to the ztest.c source on the usage.
3446 Windows 95/NT port using MSVC5.0. Project files are included in the
3449 * Defined new 'global' handle for the retrieval (data1) system. The
3450 new handled, data1_handle, describes the state of the data1 system.
3451 This handle is passed as first argument to virtually all
3452 data1 related routines. The functions data1_create and data1_destroy
3453 creates and destroys a data1 handle respectively.
3455 Added ODR encode stream member to all backend request structures
3456 init, search, scan etc. This stream should be used to allocate all
3457 memory used for the response when thread safe operation is needed.
3459 Changed the comstack utility, cs_addstr, to be thread safe. The
3460 returned hostname string returned by the function is now part the
3463 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3464 function. The cs_straddr takes a COMSTACK handle as argument, so this
3465 function must be used after cs_create and before bind/connect.
3466 This function is thread safe.
3468 Moved test server to 'ztest' directory - generic server code still
3469 in 'server' directory.
3471 Made prefix query (pquery.c) utility thread safe.
3473 Added new function modifier YAZ_EXPORT to 'export' public DLL
3474 functions when using windows (see include/yconfig.h).
3476 Added definitions to the OID database (util/oid.c) (RVDM).
3478 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3480 Added call to ccl_rpn_delete in client program.
3482 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3483 release of RPN structure.
3485 Added support for C++, headers uses extern "C" for public definitions.
3486 With input from RVDM.
3488 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3489 Thanks to Ronald van der Meer (RVDM).
3491 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3493 Added support for private extensions to the OID database
3494 (oid_setprivateoids()). Thanks to RVDM.
3496 Added optional, physical ANY (key replication)
3498 Fixed null-reference problem in GRS-1 output filter.
3500 Proximity operator added to Prefix Query Format (PQF).
3502 In test client command "base" accepts multiple databases.
3504 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3508 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3510 Smallish bug-fixes in the new encoders/decoders (explain).
3512 Bug fixed in DeleteRequest.
3514 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3516 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3518 Added SOIF syntax (using private OID for now) to retrieval module and client.
3520 Added Update extended service.
3522 Added SearchResult-1 additional info structure.
3524 Added optional CCL (ISO8777) interpreter as separate module. Available
3527 --- 1.2 1996/6/10 (1st anniversary release)
3529 Added Summary record syntax. Lightly tested.
3531 Added OPAC record syntax. Untested.
3533 Added ResourceReport service encoders/decoders. Untested.
3535 Fixed bug in z_Unit - wrong tagging on unitSystem.
3537 Fixed bug in the DiagRecs decoder.
3539 Added options for max PDU size and session timeout to frontend-server.
3541 Added documentation of query-language parsers and other supporting utilities.
3543 [frontend-server] Added Attribute set to the bend_scanrequest API.
3545 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3546 surrogate diagnostics were generated.
3548 [retrieval] Allow multiple local values for attribute.
3550 [retrieval] Allow multiple attributes per element in .abs files. index type.
3552 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3554 --- 1.1pl2 1996/4/10
3556 Minor changes, mostly specific to Zebra's requirements (retrieval)
3560 Repaired bug in frontend server when running multiple listening
3561 endpoints in dynamic mode.
3563 z_External() now won't break if a known, ASN.1 value comes encapsulated
3564 in an octet-string. The value will pass through unmodified in an Odr_oct.
3566 Added a bit of code to the demo client to decode & display
3567 ASN.1-structured records represented in the octet-aligned branch of
3568 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3570 Added z_ext_getentbyref() to the ASN module. Doc updated.
3572 * Completed the SCAN definition in the ASN module. This may break SCAN
3573 code based on older YAZ-versions at compile-time. The fix is easy -
3576 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3577 under the SCAN definition. Remember to initialize this, server-people.
3579 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3580 that this does not extend to ODR and ASN.
3582 Comstack allows insertion of established socket (primarily for
3583 inetd-operation of servers). Doc updated.
3585 Front-end server can now start from the inetd in TCP mode. Doc
3588 --- 1.0pl4 1996/1/24
3592 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3593 the rank and record number.
3595 Adjustments to the frontend server.
3597 Fixed diagnostic BER dumper. It ignored the file argument.
3601 Various changes to retrieval module.
3603 Changed the union discriminators of the protocol files from enums to
3604 ints paired with #defines.
3606 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3609 *Changed operator in the RPN structure to 'roperator', again to avoid a
3612 Fixed problems in Explain decoders/encoders.
3614 --- 1.0pl2 1995/12/6
3616 Memory bug in log module fixed.
3618 --- 1.0pl1 1995/12/5
3620 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3622 Bug in Explain DatabaseInfo module fixed.
3624 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3628 The shift to v1.0 signals that we now consider the *core* functionality
3629 of YAZ reasonably stable (the core being more or less equivalent to
3630 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3631 tested (Explain not at all - though that will happen soonish).
3633 Minor changes to code to support Windows port.
3635 Various minor changes after we're getting to use GRS-1 & co. more.
3637 Added Espec-1 format.
3639 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3640 of the protocol and it cannot be selected when encoding (maps into 'string'
3641 when decoding). Needed to talk to some servers.
3643 Demo client can request simple element set names.
3645 Added Diagnostic Format encoders/decoders.
3647 Added simple Close handling to frontend server (no hooks for resource
3648 reporting yet), and demonstration client.
3650 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3652 --- 1.0b3 1995/08/24
3654 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3655 handled incorrectly when records were requested in the searchResponse. This
3656 will only affect you if you use the frontend-server.
3658 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3659 Test-client will ask for and print GRS1. Ztest will return dummy records
3662 Added Explain encoders/decoders to the service-level API. Untested.
3664 Added Extended Services: Item Order encoders and decoders to the Service-
3665 level API. Untested. We could use a recent copy of the pertinent bits
3666 of the ILL protocol to add those bits.
3668 Added diagnostic format 1 encoders/decoders to the service-level API.
3671 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3672 odr_cons.c, which causes a more correct output.
3674 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3675 was always set to 0 when no records were requested in the searchRequest.
3677 * Added better external-handling. This shouldn't harm old code that
3678 *encodes* externals. It can break code that looks for a
3679 'single-ASN1-type' representation, since those types that are known
3680 are now decoded immediately. Look at the SUTRS sample code in
3681 seshigh.c and client.c. Documentation updated.
3683 Handling of structured records in bend_fetchresponse. Length -1 marks
3684 structured record, type is deduced from format field.
3686 --- 1.0b2 1995/06/27
3687 Fairly quick maintenance release to add SUTRS support.
3689 Fixed handling of SUTRS records in the demonstration client.
3691 * Added format field to the bend_fetchrequest and bend_fetchresponce
3692 structures of the backend API (frontend server). When the record is
3693 returned, the value of the format field is mapped to an OID. The
3694 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3695 of the record. The special value VAL_NONE in the bend_request means
3696 that no specific format was requested by the client. Documentation
3697 updated accordingly. Test server (ztest) will return a fixed dummy
3698 SUTRS record if your client requests SUTRS.
3700 Documentation updated accordingly.
3702 You can now set external libraries and RANLIB support in the top-level
3706 First public release.
