3 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
6 rpn2solr: support truncation left(2), left&right(3) YAZ-718
8 Mention SRU version 2.0 in yaz-client man page.
12 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
17 Make cs_parse_host public.A
19 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
20 introduced in YAZ 5.0.6.
24 Fix buffer corruption for yaz-ztest record fetch.
28 Allow yaz-ztest to return user-defined records (one record per file).
29 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
31 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
32 Use the stream write instead of odr_printf which has a 4K tmp buffer.
34 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
38 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
39 can read and write this format. For record format JSON, yaz-ztest returns
42 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
43 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
47 Improve error reporting for ICU chains YAZ-707
48 Report config element+rule when ICU status is "failure".
50 ZOOM: stop fetching if present response has no records YAZ-710
51 Some targets return less records than their hit count would suggest.
52 This prevents ZOOM from continuing to fetch records if any present
53 response has 0 records in the response.
55 Ensure that GFS calls exit if any listener fails YAZ-710
56 Before, if XML config was in use, it would start the default
61 yaz-ztest: -V shows version (like yaz-client -V)
63 New iconv encoding: danmarc YAZ-692
65 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
67 daemon: only wait for immediate child rather than all children. YAZ-704
69 yaz-client: fix setting of SRU record schema. If scheme was unset, it
70 could lead to invalid memory reference.
74 yaz-ztest returns schema for MARCXML test records. SRU require that
75 recordSchema for records.
77 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
78 instead of non-surrogate diagnostic. This is a per-record failure.
80 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
81 may refer to multiple listeners now. Attribute listenref is a comma separated
84 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
85 option is given for GFS, the dirname of filename (for -f) is used
86 as prefix for options such as cql2rpn, ccl2rpn, etc.
88 Content-Type charset fixes YAZ-701 . Do not inspect charset in
89 Content-Type header for SOAP when decoding SRU. The payload (XML)
90 itself tells what encoding it is. In response, never supply encoding
91 in Content-Type. The response payload (XML) tells what it is (with no
92 encoding in XML it's UTF-8).
94 HTTP decoding: allow blanks in URL paths YAZ-700
98 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
99 and facets. Ensure recordData and recordSchema are always present in
100 record element, because they are required.
102 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
105 Simplify in a lot of places using odr_strdupn.
107 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
111 Increase various buffers in GFS's statserv_options_block
112 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
113 This change makes many type-casts redundant, and, thus simplifies code.
115 Remove last bits of WAIS support.
117 Remove member 'size' from Odr_oct.
119 Slim down the public part of 'struct odr'. Most elements are not part
120 of struct Odr_private.
122 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
123 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
124 In particular facets are supported in both client - and server side.
125 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
126 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
127 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
128 both request/response). This is what a search handler in the GFS
129 will see (regardless of whether operating in SRU mode or Z39.50).
131 Changes to the srw.h (SRU/Solr) definitions include:
132 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
133 (char*), which replace union query and query_type (int). This is because
134 SRU 2.0 supports a queryType parameter. This also means that, to carry
135 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
136 x-pquery=PQFstring (extention parameter). The extension parameter
138 - New element, packing, that has information about SRU
139 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
141 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
143 New element, packing, in Z_SRW_explainRequest.
145 New elements in Z_SRW_scanRequest, queryType and scanClause.
146 These replace query_type and scanClase untion. This is similar to what
149 --- 4.2.69 2013/10/01
151 GFS: log when closing down - at least SIGTERM YAZ-684
152 Also change formatting WRT PID logging a bit.
154 Improve display of MARC records with multi-byte subfield IDs YAZ-695
155 In some rare cases subfield identifiers are multi-byte characters.
156 This will try to deterime length of those and split accordingly.
157 This affects display in line mode as MARCXML/MarcXchange. The encoding
158 of ISO2709 is the same.
160 Change inp argument to const for yaz_read_UTF8_char.
162 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
164 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
166 Better check of marc leader info YAZ-691
167 Problem is that some systems generate MARCXML/MarcXchange with
168 funny headers. These will not work if encoded as ISO2709.
169 Some tests produce new output, due to updated warning messages
171 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
173 yaz-client: display MAB records YAZ-689.
174 Thanks for Heiko Jansen for this patch.
176 New utility z_get_HTTP_Response_server which allows both HTTP server name
177 and HTTP server URL to be given in response.
179 Debian: do not depend on obs tcl8.3.
181 Debian: do not depend on obs libicu36-dev.
183 --- 4.2.68 2013/09/23
185 GFS: pass additionalSearchInfo to search memeber search_input if
186 given. Otherwise pass otherInfo. Request for facets and other search
187 related things will be passed there in future versions of YAZ.
189 New ZOOM setting, authenticationMode, which allows authentication
190 paramters to be encoded in the URL rather than via HTTP Basic auth.
193 rpn2solr: fix nested AND/OR handling. YAZ-685
195 Add comparison routines for some Z-types, such as NamePlusRecord,
196 RPNQuery, Query, RecordComposition and OtherInformation.
198 --- 4.2.67 2013/09/19
200 Don't decode MAB as MARC. Just like we don't attempt to decode
201 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
203 CCL: allow quoted terms for date ranges. YAZ-681
205 Introduce ccl_parser_qual_search. This function makes old function
206 ccl_qual_search, from YAZ 2, available again.
208 Add yaz_facet_list_to_wrbuf. YAZ-683
210 --- 4.2.66 2013/09/11
212 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
213 schema was given for search. YAZ-675
215 Add Solr date range searches. YAZ-621
217 --- 4.2.65 2013/08/22
219 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
221 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
223 ISO2709/MARC parse most octet aligned records; not just those that
224 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
225 MARC parse more records instead of just dumping as is. YAZ-670
227 ZOOM: proper caching for variations of record schema. YAZ-671
229 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
231 --- 4.2.63 2013/07/17
235 --- 4.2.62 2013/07/11
237 New utility z_get_HTTP_Response_details - an extended version of
240 New utility yaz_url_get_error which returns error message of last
241 failed yaz_url_exec call.
243 yaz-url and url functions: allow max HTTP redirects to be controlled.
245 New functions yaz_file_glob2, yaz_xml_include_glob.
246 These functions takes a flags parameter, which, for now only controls
247 whether to fail inclusion of a non-existing file (without glob
248 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
250 --- 4.2.61 2013/06/20
252 For MARC XML parsing, allow record without leader. A fake/default leader
253 is inserted and a warning is tagged with the record.
255 ICU: fix leak in in icu_iter_get_org_info.
257 --- 4.2.60 2013/06/14
259 ICU: fix bug in icu_iter_get_org_info (un-init variable).
261 --- 4.2.59 2013/06/11
263 Implement z_HTTP_header_remove.
265 --- 4.2.58 2013/06/11
267 ICU: Disallow 0 ptrs for some ICU string utilities.
269 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
270 returns original tokens (before normalization).
272 CCL: avoid z39.58/regex truncation when not needed. Apply only the
273 conversion of those masks, when absolutely necessary.
275 CCL: configurable masking character - @mask. Default masking character
278 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
279 full response anyway, so a Transfer-Encoding header will obstruct the
282 --- 4.2.57 2013/05/15
284 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
285 picking a socket. Problem is that some systems has IPV6 support, but
286 we can't create sockets for them, so we pick AF_UNSPEC first.
288 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
289 use content_len to determine resulting Content-Length in HTTP response
290 and NOT Content-Length supplied in headers by user.
292 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
293 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
295 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
298 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
299 with big endian and unsigned char (by default).
301 --- 4.2.56 2013/04/26
303 Fix yaz-client connect (crash in 4.2.55).
305 --- 4.2.55 2013/04/26
307 Fix proxy/host problem for ZOOM that could occur if unix sockets
310 New Debian package libyaz4-dbg.
312 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
313 differently in tcpip_close.
315 --- 4.2.54 2013/04/17
317 Windows installer of YAZ includes YAZ4J as a component.
319 CQL: allow "extra terms" again, by default. Thus, the CQL parser
320 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
321 and earlier. CQL parser may operate in strict mode where queries
322 not conforming to the standard BNF are rejected (syntax error).
323 Whether the CQL parser operates in strict mode is controlled with
324 cql_parser_strict . Strict mode enabled with option -S for utilities
325 cql2pqf and cql2xcql .
327 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
329 --- 4.2.53 2013/04/10
331 New charset, MARC-8c, which is like MARC-8 but allows control characters
332 0x01 through 0x1F, except ESC to be passed through verbatim.
334 Fix a problem with duplicate sub field character in MARC output. Problem
335 happened only when output was MARC-8 encoded.
337 --- 4.2.52 2013/04/03
339 yaz-ztest: Use hash for fake hit count. Before, random number was used.
340 This is problematic for unit tests using yaz-ztest. This patch also makes
341 a hash for CQL queries. For RPN, any term with a leading digit will be
342 treated as pseudu hit count (to force any particular hit count by a client).
344 yaz-ztest: return unique MARC dummy records. Beyond record offset
345 24, the author surname is patched with offset to make all records
348 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
349 on system wide default (/proc/sys/net/ipv6/bindv6only).
350 @4 binds to IPV4 only. @6 binds to IPV6 only.
352 Update CQL API documentation a bit
354 CQL: don't accept extra terms for queries. Makes the CQL parser
355 stricly conformant to the standard.
357 --- 4.2.51 2013/02/12
359 GFS: scan handler gets extra_args from request and may return extra
360 response data . That's for SRU only.
362 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
364 --- 4.2.50 2013/01/30
366 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
368 OPACXML: sync spelling of availabilityDate in XML to that of Schema
369 opaxxml.xsd. The schema had the correct spelling of this member always.
370 The ASN.1 was mis-spelled and still is (API change) - we are
371 not changing this. However, the OPAC to XML conversion had yet
374 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
377 New function, z_ext_record_oid_nmem, which is similar to
378 z_ext_record_oid but takes NMEM rather than ODR
380 --- 4.2.49 2013/01/18
382 ICU: New conversion element 'join' which joins tokens into one
383 with a custom character given by rule attribute.
385 --- 4.2.48 2013/01/10
387 New GFS search member: present_number. This is a hint to the
388 search handler how many records are going to be fetched immediately
389 following search. There's no guarantee that it's going to be the case,
390 since it depends on hit count (for Z39.50 piggyback) and whether errors
393 Make a few functions static (private). The functions getbyte_stream,
394 ungetbyte_stream and yaz_gets are now private. They were never declared
397 yaz-marcdump: exit(5) for serious decoding errors
399 ISO2709 decoding: be more picky WRT header
401 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
402 was only used as to indicate that next-result-set-position should be
404 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
405 Based on patch from Ashley Sanders.
407 Make some functions static/private in PQF parsing. Those functions were
408 never declared in a public header and so should not be in use by
409 applications based on YAZ.
411 --- 4.2.47 2012/11/23
413 ZOOM: special options to control APDU logging.
414 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
415 logging of APDUs until "saveAPDU" option is set again. If logging is
416 already enabled the effect is that current APDU buffer is cleared.
417 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
418 logging (default behavior on new connection).
419 The APDUs sent/received can be obtained by using
420 Using ZOOM_connection_option_get(c, "APDU") or
421 ZOOM_connection_option_getl(c, "APDU", &l).
423 GFS: relay implementation_version from backend
424 From 3.0.40 and later, implementation_version from backend was
425 not used in init response at all.
427 --- 4.2.46 2012/11/15
429 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
430 mode at all. Probably never did.
432 Make a new version of ztest.pem that, at least, is not expired.
434 --- 4.2.45 2012/11/13
436 Fix description of CCL directive 'case'.
438 More tight checking of form arguments (yaz_uri_to_array). Makes
439 YAZ better at rejecting big and/or bad POSTs.
441 SRU decoding does not report more than up to 10 invalid arguments.
443 rpn2cql: less quotes in generated terms. Semantics unchanged, but
444 it's prettier this way.
446 --- 4.2.44 2012/10/25
448 New utility yaz_decode_init_diag. Defined in proto.h.
450 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
451 given for unix local socket.
452 The COMSTACK string for doing so is:
455 unix:/myfile:tcp:localhost:9999/mybase
456 unix:/myfile:localhost:9999/mybase
457 unix:/myfile:http://fakehost/mybase
459 debian: Use dpkg-buildflags in build process.
461 --- 4.2.43 2012/10/19
463 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
464 global's SRU service uses a recordPosition scheme starting from zero.
465 First record's position should be one
466 according to the standard.
468 --- 4.2.42 2012/10/18
470 Allow more namespaces for SRU. This is to allow, for example, an
471 incorrect namespace returned from server
472 http://services.igi-global.com/sru .
474 Minor fixes for compilation on Windows.
476 --- 4.2.41 2012/10/11
478 daemon: log total number of bad signals from child on stop so that it
479 is more easy to spot problems with child worker processes.
481 retrieval: empty backend name attribute omits element set
482 from being used in retrieval.
484 --- 4.2.40 2012/10/04
486 Implement Solr sort strategy "solr", similar to sru11 sorting.
487 This will implement the correct parameters on Solr requst to do
490 --- 4.2.39 2012/09/28
492 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
495 MARC: Extra/missing indicator handled for MARCXML.
496 The indicator length is given in header and is the same for the
497 whole record. If attributes ind1, ind2 are missing, then content
498 character defaults to blank. Extra indicator attributes (beyond)
499 indicator length are treated as an error.
501 Reformat: delete trailing whitespace
503 --- 4.2.38 2012/09/17
505 MARC: fix non-ASCII characters for leader. This is to ensure we can
506 generate XML in UTF-8.
508 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
509 in one node with structure word.
511 --- 4.2.37 2012/09/04
513 yaz-json-parse: JSON output may be pretty printed by using option
516 Increase default value of max message for Z39.50 Init for GFS, ZOOM
517 and yaz-client. Old value was 1 MB. New value is 64 MB.
519 --- 4.2.36 2012/08/22
521 yaz-client: don't display bogus records from SRU servers. Some SRU servers
522 return more records than given by *maximumRecords*. Skipping those in
525 record_render: simplify buffer return handling and fix at least one bad
526 memory reference, that broke the test_embed_record sometimes.
528 Allow http://user:pass@host notation for yaz_url_exec.
530 zoomsh: allow shell command to be executed. Via the system(3) call.
532 yaz_poll: Allow num_fds == 0
534 yaz-client: fix bad encoding of "itemorder item". The itemorder
535 item <no> - command forgot to use length of encoded Item Request
536 package. Error present since YAZ 3.
538 yaz-ztest: fix bad usage of session handle. Bug was introduced when
539 result sets were saved (271a9c83).
541 SRU recordPacking: guess record packing in response rather than looking
542 at the recordPacking element which, OF COURSE, changed semantics in SRU
545 Decode SRU 2.0 responses. The official namespace for responses, according
546 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
547 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
548 nature.com's server, however, usee namespace
549 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
550 we are now using a glob-expr to match up the namespace. ZOOM C and
551 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
552 I can not find a single real example showing the "real" namespace in
553 the documentation from OASIS. The namespace for requests is different
554 from responses, but this is not added to YAZ yet, when we don't encode
557 --- 4.2.35 2012/06/26
559 zoom/record_render: add support for Base64 decoding fo MARC records
560 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
561 which will decode base64 + ISO2709 marc-8 encoded material from text node
564 --- 4.2.34 2012/06/07
566 Add missing definitions ZOOM_resultset_get_facet_field_by_index
567 and ZOOM_resultset_facets_names.
569 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
572 Change APDU dump printing to avoid long leading blanks. For levels 16
573 or larger the level is shown and the indentation is truncated but
574 recursed with modula 8. This makes it still reasonable easy to read
575 - even for nested BER dumps.
577 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
578 return 0 (incomplete package) in case where the BER package was
579 considered too nested (return value of -2).
581 dumpber: lines of level 15 are not indented further. Two spaces per
582 indentation; indentation 15 or more is indented to a fixed indentation
583 and augmented with a level=<no> indication.
585 zoomsh: increase max size of command+args
587 GFS: No limit in RPN buf size in CQL to RPN conversion.
589 --- 4.2.33 2012/05/09
591 New function for daemon utility, yaz_daemon_stop .
593 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
595 --- 4.2.32 2012/04/25
597 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
598 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
600 --- 4.2.31 2012/04/23
602 YAZ daemon utility relays SIGUSR1 to child process.
604 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
605 would result in en empty database list - which in turn would result in
606 encoding failure for search.
608 Fix reading beyond string in yaz_sort_spec.
610 --- 4.2.30 2012/04/11
612 Add two new SRU diagnostics:
613 236: Access to specified database denied
614 1015: Init/AC: Maximum number of simultaneous sessions for Userid
616 Document the very useful ZOOM-C option "apdulog".
618 CQL to RPN: term may be passed through verbatim. This is enabled with
619 truncation.cql . The assumption being that the term is already CQL.
621 --- 4.2.29 2012/03/20
623 record_conv: leader spec may be given for marc element.
624 The leader spec is given as attribute leaderspec for element marc.
625 For example to convert a MARC21 record from MARC-8 to UTF-8:
626 <marc inputformat="marc" outputformat="marc"
627 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
629 record_conv: allow user-XSLT params. For example:
630 <xslt stylesheet="MARC21slim2DC.xsl">
631 <param name="myparameter" value="myvalue"/>
632 <param name="otherparameter" value="othervalue"/>
635 record_conv: fix error handling for missing marc charsets.
637 CQL: fix extra terms in wrong order.
639 --- 4.2.28 2012/03/06
641 record_conv: modify new API for conversion types. The conversion types
642 may be passed in new functions yaz_record_conv_configure_t and
643 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
645 Avoid mixed statement/variable declare; fixes compilation with Visual
648 --- 4.2.27 2012/02/28
650 Add non-standard SRU diagnostic: 235: "Database does not exist".
651 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
652 Update SRU to Bib-1 diagnostic maps accordingly.
654 CCL: add two new diagnostics for unsupported masking. The new
655 diagnostics are: "Embedded truncation not supported" and
656 "Single charcacter mask not supported".
658 --- 4.2.26 2012/02/23
660 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
662 --- 4.2.25 2012/01/11
664 Build YAZ for Ubuntu Oneiric.
666 CCL: allow parantheses for proximity operands. For example CCL query
667 (a) % (b) is now allowed.
669 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
670 marked dead, rather then being destroyed. If not, the session memory is
671 being free'd before the search/scan handler is finished. Also destroy
672 'request' memory in request_release rather than in various places,
673 which resulted in leaks from time to time.
675 --- 4.2.24 2011/12/21
677 cql_sortby_to_sortkeys: honor sort prefix.
679 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
680 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
681 The rpn2cql family of functions now always returns quoted CQL terms.
683 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
685 --- 4.2.23 2011/12/15
687 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
688 sequence is treated as one. For example, &&a=b&&&c& is identical to
691 --- 4.2.22 2011/12/05
693 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
694 APDUs for a connection to a WRBUF.
696 --- 4.2.21 2011/11/23
698 Fix cql_sortby_to_sortkeys. Completely broken before.
700 Make CCL's @truncation work again.
702 --- 4.2.20 2011/11/09
704 New ZOOM connection setting: tproxy. It's like proxy, but does not
705 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
706 to set resolved address + port for a connection outside ZOOM itself.
708 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
710 --- 4.2.19 2011/11/07
712 Fix uninitialized variable in Solr spell support (could cause SEGV
713 for SRU response decoding).
715 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
716 back-end's addinfo through into the ZOOM response addinfo.
718 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
719 they are separated by a colon and a space rather than simply
722 --- 4.2.18 2011/10/28
724 Add support for Solr spell-checking/suggestions through ZOOM.
725 If a Solr target has been configured correctly for spelling-checking
726 and suggestions, these will now be returned on the ResultSet option
727 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
729 --- 4.2.17 2011/09/28
731 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
732 with a flag whether to substitute escape sequences or not.
734 --- 4.2.16 2011/09/22
736 Fix nmem_strsplit_escape to substitute escape char properly.
738 New option for zoomsh -e , which makes it abort on first error and
739 return process exit code to indicate success/failure.
741 YAZ options utility supports special option -- which makes all it treat
742 all following arguments as non-options.
744 --- 4.2.15 2011/09/16
746 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
747 searched if absolute filename is given.
749 Fix conv_xslt() error-reporting when stylesheet is not found.
750 (The value of fullpath is meaningless in this situation.)
752 --- 4.2.14 2011/09/07
754 Fix problem in CQL sort node creation: un-initialized memory.
756 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
757 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
758 CQL sortby depending on whether Type-1 or CQL is actually sent to the
761 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
762 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
764 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
765 will make it possible to use both single-character mask (#) and wildcard (?)
766 in CCL . Throw diagnostic for left truncation because that is not supported
769 --- 4.2.13 2011/09/01
771 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
772 cases using escapes (\-sequences) and masking.
774 PQF parse fix: A trailing backslash followed by end-of-string (\0)
775 would result in a read one byte beyond string.
777 rpn2ccl may use Z39.50 masking for terms (t=z).
779 ICU check fix. Don't include library -lCrun on Solaris, unless present.
781 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
782 not --cppflags (which seeems like an error in icu-config).
784 --- 4.2.12 2011/08/27 RPM package only
786 cql2ccl: fix conversion of terms: operator characters were not
789 --- 4.2.11 2011/08/25 RPM package only
791 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
792 CCL parser will map both # and ? to their regular expression
793 quivalents (. and .*).
795 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
796 of reserved CQL characters.
798 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
799 is, so that they are passed through.
801 --- 4.2.10 2011/08/24
803 ZOOM SRU mode: more aggressive re-connect.
805 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
806 made available as a utility function, declared in <yaz/logrpn.h>
808 rpn2cql_structure() supports proximity nodes (except that the Type-1
809 proximity node's "exclusion" binary is ignored, as there is no way to
810 express that in CQL). Fixes bug #4564.
814 Fix SEGV that could occur if set command of zoomsh was given without
815 value (2nd argument).
817 Fix SEGV that could occur if unsupported transport was given for
818 COMSTACK - say https (when SSL was unavailable).
820 Build yaz-url on Windows too.
824 New utility to get web content. Header is url.h. A command line tool
825 yaz-url is part of the distribution and packages.
827 Fixes for SSL COMSTACK (when gnutls is in use).
829 New functions yaz_base64{encode,decode}. Header is base64.h.
833 ZOOM C includes HTTP response buffer as additional info if it fails
834 to decode the SRU response.
836 Make wrbuf_json_puts available.
840 zoom: throw diagnostic for invalid value for option "sru". Before a
841 bad SRU request was sent.
843 Adding new utility wrbuf_vp_puts.
845 Add cclxmlconfig.obj to win/makefile. It was missing completely.
849 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
850 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
851 redirect was used at the same time.
853 MARC line mode decoding: be less picky about length given - first
854 5 digits of header that is.
856 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
858 Changes to decoding of SRU records: a record with recordPacking=xml is
859 modified with a new root element <yaz_record> if the recordData contains
860 multiple children elements. This is to make the record XML parseable
863 RPN to Solr conversion: encode special characters.
865 Generic Frontend Server: fix uinitialized member, stepSize.
869 Fix a bug in SRU decoding of records.. The database records stored
870 had un-initialized memory, but it would only be seen with yaz_record_render
871 and type_spec="ext" .
873 Fix a bug in ccl_qual_dup introduced in 4.2.3.
877 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
881 Add new utilities to convert from CQL to CCL . These utilities have
882 prefix cql_to_ccl defined in cql.h.
884 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
885 lead to memory heap corruptions when ICU utilities were in use.
889 Make compilation work without Libxml2.
891 yaz-client: remove redundant blanks in display of searchResult-1 term
896 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
897 resulting CQL node (tree) in a new node CQL_NODE_SORT.
899 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
900 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
901 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
902 Note that the CQL sortby spec is only converted when the GFS is already
903 converting from CQL to RPN (cql2rpn element).
905 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
906 specify whether to collapse delimitors or not. The existing nmem_strsplit
907 do collapse (collapse parameter = 1).
909 Windows installer: For NSIS, set InstallDir depending on x86/x64.
911 Rename internal func yaz_use_attribute_create. While non-static, this
912 function is not declared in a public header.
916 Add -lCrun when linking with ICU on Solaris.
918 More quicks character set conversions for OPAC records.
922 fix problem with record_render: records were converted (character set
923 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
927 SRU: add methods for handling DADS SRU-proxy facets.
929 Separate OPAC record character set for ZOOM_record. yaz_record_render
930 allows a character set given as charset=from/opacfrom,to where 'from' is
931 the character set of a bibliographic record, 'opacfrom' is character set
932 of OPAC record and 'to' is the target character set.
936 yaz-client: show may XML format records. Command show followed by 'format'
937 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
940 src/stemmer.c: Avoid using unnamed union. It is not supported by some
943 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
946 Update yaz.spec to operate on both SLES11 / Centos 5.5.
948 RPM: Release includes 'indexdata' name. Use indexdata in release name so
949 this package can be distinguished from other vendors.
951 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
952 as determined by configure
954 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
956 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
957 returns no error and no record, the present request is considered
958 partial (only a subset of the records could be returned by backend), and
959 so it is appropriate to set Present Status to partial-4.
963 Move yaz-config man pages to section 1.
965 More documentation about Solr.
967 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
968 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
969 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
970 peers on some Linux systems. However, in general that does not work
971 so YAZ can not rely on that to work. Debian changed behavior in this
972 respect from Debian lenny to Debian squeeze (still testing as of Oct
974 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
976 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
980 Fix yaz-config output: echo_source not set correctly by configure.
984 Solr Web Service support for yaz-client and ZOOM.
986 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
988 --- 4.0.12 2010/08/17
990 Z39.50 facet support. Facet specifications are passed for search in
991 other-information with ASN.1 as defined in facet.asn and OID
992 .10.1000.81.5 . Facets are expressed as an Attribute list as known
993 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
994 3 is limit (number of entries to get in response). yaz-ztest returns
995 dummy facets if a client asks for them.
997 --- 4.0.11 2010/07/09
999 CCL fixes: bug 2895 and bug 3539.
1001 GR1-display: add comma in display - was removed by mistake in
1004 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1006 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1008 --- 4.0.10 2010/06/18
1010 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1011 result set from a connection. The result set will be on its own
1012 thereafter; no operations on it will perform retrievals from a target.
1013 Only cached copies are returned.
1015 ZOOM C:fix case for HTTP servers responding with Connection:close.
1016 Ensure that if there is a current task it is resumed (like fetching
1017 more records in a result set) . Bug #3484.
1019 PQF parser: use odr_atoi for Odr_int (not atoi)
1021 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1022 values that contain any non-digits are treated as string attributes
1023 (previously decoding only checked for leading character ([0-9]). PQF
1024 encoding: attribute string values are not surrounded by double-quotes.
1026 --- 4.0.9 2010/05/21
1028 New utility for managing threads - thread_create.h.
1030 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1031 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1032 but YAZ' implementation do.
1034 Fixes for yaz_cond-functions on Windows 7.
1036 DLL export more symbols.
1038 zoomsh: show record do NOT render opac.
1040 Remove *.la files from Debian and RPM packages.
1042 --- 4.0.8 2010/05/11
1044 Debian package libyaz-dev depends on libgnutls-dev again (was
1045 removed in YAZ 4.0.6, but due to Libtool it is still needed
1046 even though yaz-config do not list libgnutls libs).
1048 ZOOM: Use only one WRBUF for returning string results for
1049 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1051 ZOOM: ZOOM_connection do not use a shared pointer to
1052 ZOOM_resultset after ZOOM_resultset is destructed by
1053 user. Reverts to YAZ 4.0.4 behavior.
1055 --- 4.0.7 2010/05/04
1057 record-conv: fix problem with at least one XSL conversion -
1058 due to probably incorrect usage of XML XSL documents.
1060 --- 4.0.6 2010/04/29
1062 Fix yaz-config for static mode and the use of SSL (gnutls).
1064 --- 4.0.5 2010/04/29
1066 Forward decl timeval struct in mutex.h and gettimeofday.h.
1068 yaz-config: fix 'static' mode linking.
1070 --- 4.0.4 2010/04/28
1072 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1073 are wrappers for pthreads or Windows. For Windows these are put in
1074 a separate DLL: yaz_cond4.
1076 libyaz.la (whole source) is compiled with thread. If thread support
1077 is enabled enabled, all source of YAZ is compiled with treading support.
1078 This allows core utilities such as yaz_log to use thread facilities.
1079 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1080 thread utilities. This commit moves mutex utilities (mutex.c) from
1081 libyaz_server.la to libyaz.la.
1083 yaz-json-parse displays leading text until error.
1085 --- 4.0.3 2010/04/09
1087 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1088 patch from Giannis Kosmas.
1090 SRU: no longer URL encode SRU database. The URL for an SRU server is
1091 a URL and such is alreeady encoded - at least when given with leading
1092 http:// or https://. This reverts behavior to YAZ 3.0.50.
1094 Support for new MARC XML notation TurboMARC which like MARCXML is a
1095 complete representation of MARC/ISO2709.. This one, however, is more
1096 compact and allows for faster processing with XSLT. TurboMARC can be
1097 used in the marcdisp.h API, from the yaz-marcdump utility and from
1100 yaz-ztest can be configured - via the database - to perform certain
1101 delays when it performs operations search, present and single record
1102 fetch. This allows testers to make yaz-ztest act as a real or even slow
1103 Z39.50 server. Refer to the yaz-ztest man pages for details.
1105 --- 4.0.2 2010/03/09
1107 wrbuf_destroy allows NULL WRBUF passed to it.
1109 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1111 Add ZOOM_connection_close.
1113 No fixed size buffers for ZOOM shell - bug #3257.
1115 tstodr: make it work on s390 platform.
1117 New icu iterator-functions. The new icu_iter-functions makes it possible
1118 to use ICU chains from many threads.
1120 yaz-client: better syntax check for show command.
1122 --- 4.0.1 2010/01/26
1124 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1127 New simple local-file XML include facility which allows file glob-patterns.
1128 Refer to yaz/xml_include.h.
1130 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1133 ZOOM_record_get supports new parameter "format" which makes it format XML
1136 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1137 JSONText in ECMA-262) is JSONValue, not JSONObject.
1139 --- 4.0.0 2010/01/20
1141 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1142 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1144 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1145 POSIX/Unix builds .so with major version 4.
1147 Remove old LOG_-defines from log.h. They have been obsolete and
1148 undefined by default for the last 5 years.
1150 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1152 GFS: Remove socket (int *fd) from search_rr handler. The socket
1153 descriptor ptr is a facility that allowed a search handler to supply
1154 a socket which would serve as a callback - when search was complete.
1155 This facility has now been in use for years.
1157 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1158 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1159 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1160 returns 'const char *' rather than 'char *. The returned string is
1161 read-only and should not be modified by applications. COMSTACK cs_close is
1162 now a void function - it no longer returns int. No applications check for
1163 the value and the implementations has always returned 0.
1165 ZOOM: use size_t for scan hit counts and str size. Functions
1166 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1167 occ (hit count) and len (string length) are now of type size_t pointer
1168 rather than int pointer. This is to be able to represent large hit counts
1169 and to also just to use the proper type for string length (strlen result).
1171 New JSON parser. Refer to include/yaz/json.h .
1173 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1174 Used to be int in some cases. Many wrbuf_-functions used to return an int
1175 indicating some length.. These return values were never used. And so they
1178 ODR: odr_malloc, odr_total now takes size_t for size.
1180 clone_z_type: fix leak; occurred for encoding failures.
1182 --- 3.0.52 2009/12/03
1184 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1185 bug was introduced in 3.0.51.
1187 --- 3.0.51 2009/12/02
1189 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1191 tcpip comstack: fix leak for getaddrinfo.
1193 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1194 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1195 Decoding of SRU "path" database is performed by private function
1196 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1197 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1199 yaz-client: honor base command for SRU. Change when database setting
1200 is applied for SRU and ensure it is kept when a connection is reset.
1201 Change also the way errors are displayed or SRU (decoding of packages).
1203 --- 3.0.50 2009/11/02
1205 Add support for extra request / response data for SRU codecs and GFS.
1206 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1207 for extra data response buffer and length. For the GFS, both request
1208 and response data (XML) is carried in extra_args and extra_response_data
1209 for the search handler. Patch by Ko van der Sloot.
1211 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1212 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1213 10010). This fixes bug #2113.
1215 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1216 cmdfile included a 'quit' command that would result in a memory violation.
1218 --- 3.0.49 2009/10/01
1220 Make a number of functions defined in xmlquery.c static. These have
1221 never been declared in a public header file (yaz/xmlquery.h) and was
1222 made public by mistake.
1224 Improve speed of character conversions (iconv utilities). This makes
1225 conversions from MARC-8 faster.
1227 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1228 unless type desired is "raw". This will prevent type "xml" from
1229 returning ISO2709 .. Which obviously can not be XML parsed.
1231 Fix memory leak in ZOOM that would occur if option apdulog was used
1232 on a re-used connection.
1234 Frontend server logs HTTP requests.
1236 Frontend server now sends Z39.50 close when it times out (sesssion has
1237 been idle for too long). Versions 2.0.30 and earlier also sent close.
1238 But due to a mistake this was disabled in all versions after that, i.e.
1239 the server would just close the socket immediately.
1241 yaz-client emits a better message when receiving an unrecognised
1242 userInformationField.
1244 Skip zero-length subfields when decoding ISO2709. This rare case happens
1245 if a record has two FS characters in a sequence. Without this patch
1246 there would be a reference beyond char array in using_code_len fragments
1249 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1251 --- 3.0.48 2009/08/28
1253 The show command offered by the zoomsh command now takes a 3d optional
1254 parameter type which is what is passed to ZOOM_record. If the type
1255 argument is omitted, "render" is used.
1257 RPN to CQL conv may use USE string attributes (bug #2978).
1259 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1261 --- 3.0.47 2009/07/08
1263 Function yaz_xml2query allows a diagnostic element in the PQF XML
1264 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1265 code and additional info respectively.
1267 The BER BOOLEAN is now the integral type Odr_bool which still happens
1268 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1269 typedef'd to Odr_int. This is still an integral 'int', but it may be
1270 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1271 ASN-1 compiler as well as programs has been updated to use the new types.
1273 --- 3.0.46 2009/06/08
1275 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1276 only the bibliographic record was rendered. For type=opac, an OPAC
1277 record is only returned if it is present.
1279 iconv: small fix for encoding of advancegreek.
1281 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1283 yaz-client: option auto_reconnect=on really reconnects.
1285 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1287 server: avoid null ptr ref for for yaz_poll errors.
1289 build: fix RPM build for RHEL 5.3.
1291 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1293 --- 3.0.45 2009/03/31
1295 Fixed bug #2709: TCP connect returns Invalid argument.
1297 Fixed compilation for mingw.
1299 Honor charset for raw records (ZOOM_record_get).
1301 Fixed use of errno for threaded mode that was seen on Solaris 10.
1303 Fixed argument passing with blanks in value for Windows Service.
1305 Disable YAZ' own log rotate by default (no 1 GB limit).
1306 The variable l_max_size which specifies the log file limit is set to 0
1307 (DISABLED): This is due to the fact that YAZ is most often deployed using
1308 logrotate. Also YAZ can not perform log rotate because of unsufficient
1309 permissions (setuid).
1311 --- 3.0.44 2009/02/17
1313 List supported encodings in man page for yaz-iconv.
1315 Fixed missing SSL libs for --libs output
1317 Re-established OID record syntax application-xml. Nobody should use it
1318 but we don't want to change soname because of this symbol being absent.
1320 --- 3.0.42 2009/02/02
1322 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1324 Added member named_result_sets for init handler struct for the GFS. This
1325 allows a server to disable named result sets.
1327 Removed OID record syntax application-xml.
1329 Added support for rule-based transliterator for ICU wrapper of YAZ.
1331 Fixed bug #1902: yaz-icu XML output.
1333 Make YAZ checks Emacs friendly.
1335 BITSTRING value shows value. Bug #2346.
1337 ISO2709 decoding: skip control characters from indicator data.
1339 Omit sort key by default in yaz-icu's output.
1341 Allow combined single char options (again) for YAZ' options function.
1343 Utility yaz-marcdump got option to display YAZ version (-V).
1345 Allow YAZ to use ICU 3.4.
1347 Added new ICU test case which illustrates removal of diacritics.
1349 --- 3.0.41 2008/12/29
1351 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1353 --- 3.0.40 2008/12/29
1355 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1358 Fixed bug #2352: yaz-marcdump crashes for certain record.
1360 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1362 Added support for Danmarc2 to UTF-8 conversion.
1364 Added support for ISO5426 to UTF-8 conversion.
1366 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1367 implementation version.
1369 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1371 --- 3.0.38 2008/11/10
1373 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1374 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1376 ZOOM C now interprets databaseName option for ZOOM connection as path
1379 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1381 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1383 Dummy Libxml2 types no longer defined in headers of YAZ'.
1385 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1388 --- 3.0.36 2008/09/26
1390 Various ODR chapter fixes.
1392 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1394 Added missing source for Windows compilation, mutex.c.
1396 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1398 For SRU connections in ZOOM all records up to "count" are now fetched.
1400 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1401 in Windows due to bad error handling for Libxml2.
1403 Added facility for sending arbitrary records (ASN.1 any) using
1404 ZOOM C's Extended service update. Patch by Sam Reynolds.
1406 New options for ZOOM C's connection, logapdu which makes ZOOM log
1409 --- 3.0.34 2008/06/18
1411 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1413 --- 3.0.32 2008/06/12
1415 Fixed memory violation that could occur when decoding UTF-8. This bug
1416 was only present in 3.0.30 of YAZ.
1418 --- 3.0.30 2008/06/06
1420 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1421 GNU TLS is used by default (if found).
1423 yaz-ztest returns OPAC records if a client asks for OPAC.
1425 Improved speed of MARC-8 encoding.
1427 Added support for lossy and loss-less MARC-8 encoding.
1429 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1431 Added new Windows Service wrapper (sc).
1433 yaz-client's itemorder command may now send a file.
1435 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1437 Added new function yaz_log_xml_errors.
1439 Allow (but warn) unknown XML attributes in MARCXML parsing.
1441 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1443 The UTF-8 to MARC-8 conversion now uses a different set of characters
1444 for Greek symbols. Bug #2120.
1446 --- 3.0.26 2008/02/21
1448 Added yaz_daemon (daemon.h).
1450 Fixed bug #2068: pkg-config trouble
1452 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1454 --- 3.0.24 2008/01/28
1456 Document --with-xml2 option.
1458 Added OPAC XML XSD (etc/opacxml.xsd).
1460 Allow glob mask for name attribute in retrieval element for the
1461 generic frontend server's retrieval facility.
1463 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1464 except POLLIN/POLLOUT.
1466 Fixed error handling in cs_listen. Bug #2037.
1468 --- 3.0.22 2008/01/20
1470 Fixed version in yaz/yaz-version.h.
1472 Fixed bug #2027: Crash when closing connection.
1474 Changed configure so that ICU support is only enabled if only ICU
1475 and Libxml2 is available (because the ICU chain is XML based).
1477 --- 3.0.20 2008/01/15
1479 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1480 is built. Only this DLL depends on the ICU runtime.
1482 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1483 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1485 Changed license of CCL module to 'Revised BSD'. After consultation with
1486 remaining members of the original EUROPAGATE consortium, we are re-issuing
1487 the CCL module without a separate license. The software was developed by
1488 Index Data as part of a research project. The special license was included
1489 to help feed usage information back to the project consortium to support
1490 project evaluation. At this time, the project consortium has long-since
1491 disbanded, and the majority of the original principals have retired. At the
1492 same time, we have significantly modified the software during the following
1493 years, to the point where very practically no original code remains. To
1494 simplify re-use of the software, we have contacted those members of the
1495 consortium who could be reached, and agreed to re-issue the module as a
1496 proper part of the YAZ package.
1498 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1500 CQL closer to being version 1.2 compliant. CQL also allows free-form
1501 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1504 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1505 bug could make Extended services handling crash in the ZOOM layer. This
1506 bug was only present in YAZ 3.0.18.
1508 --- 3.0.18 2007/12/19
1510 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1513 yaz-marcdump reads and writes collection wrapped records.
1515 Handle OPAC for record conversion module.
1517 Fixes for ICU wrapper.
1519 Allow ICU libs to be controlled with --with-icu .
1521 --- 3.0.16 2007/11/12
1523 Added yaz_poll which is a wrapper for select/poll. When poll is available
1524 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1525 sockets to be in use.
1527 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1528 functionality through an XML based configuration (ICU chain). This system
1529 is useful for search facilities such as Pazpar2 and Zebra that needs to
1530 perform tokenization of indexed material. The ICU code in a separate
1531 library libyaz3_icu.a.
1533 Added HTTP tunnel facility for COMSTACK, bug #1752.
1534 This is a facility that allows a Web proxy, such as squid, to tunnel
1535 Z39.50 traffic. This facility is "transparent" to must applications
1536 using YAZ. It's enabled by using pseudo transport connect: followed by
1537 the proxy address, followed by command, then follwed by he regular
1538 "virtual" addresss. For example,
1539 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1541 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1543 --- 3.0.14 2007/09/21
1545 Fixed bad memory reference in ZOOM_record - cuased by member not being
1546 initialized. This was a problem only in YAZ 3.0.12.
1548 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1549 fields were not removed.
1551 Changed the way C code is generated from codetables.xml. Made a MARC-8
1552 conversion trie for each characterSet section rather than codeTable.
1553 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1554 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1556 --- 3.0.12 2007/09/12
1558 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1559 from ZOOM_record_error).
1561 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1563 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1565 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1567 Better SRW-to-Bib-1 diagnostic mapping.
1569 ZOOM C and yaz-client announces SRU version 1.2 by default.
1571 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1574 Fixed in yaz_sru_decode to allow other version than 1.1.
1576 --- 3.0.10 2007/08/22
1578 Added support for SRU scan for ZOOM.
1580 Added support for the use of the older versions or Extended Service
1581 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1582 set to the version , 1=first, 2=second, 3=third. The third version is
1583 what ZOOM C has used so far. And that, obviously, is the default.
1585 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1586 therefore in Zebra and in SimpleServer-based applications). The new
1587 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1588 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1589 which is passed into the back-end search callback function.
1591 Added support for HTTP Basic authentication in clients: the SRU/W
1592 codec encodes the username/password elements of the PDU structure
1593 appropriately, and these may be set using the "user" and "password"
1594 options in ZOOM-C applications (the same options that are used for
1595 Z39.50 authentication).
1597 --- 3.0.8 2007/06/25
1599 Fixed bug #1208: SSL appears to be broken in ZOOM.
1601 Fixed bug #1206: Libxml2 include path weirdness.
1603 Added oid_name_to_dotstring.
1605 Allow elementSetName to be specified for ZOOM C record update.
1607 Allow waitAction to be specified for ZOOM C based for Extended Services.
1609 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1610 syntax OID. Bug introduced in YAZ 3 series.
1612 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1614 --- 3.0.6 2007/06/06
1616 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1617 directory. yaz-client now reads commands from file given by option -f
1618 if specified; then tries to read .yazclientrc in current directory.
1619 Failing that, it reads .yazclientrc from user's home directory.
1621 Added support for correlationInfo Note and ID for Record Update via
1624 Added yaz-client command querycharset which specifies character set for
1625 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1626 (termListAndStartPoint).
1628 Charset ISO5428:1984 is an alias for ISO5428-1984.
1630 Implemented a way to perform scan in a result set using Z39.50. This
1631 is achieved by attaching the result set name in the characterInfo
1632 (type InternationalString) of OtherInformation in the Scan Request PDU.
1633 The result set is identified in the otherinformation by the new OID:
1634 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1635 This allows for scan in result set and faceted search . Zebra did some
1636 of this in the APT term using attribute type 8 and value being result
1637 set. Using the OtherInformation approach for this is cleaner and easier
1638 to work with in proxies and the like. This facility can be used in
1639 yaz-client using new command setscan which takes a result set as first
1640 argument, start position (APT) as second.
1642 Changed decoding of SRU XML packed records to deal with servers that
1643 have recordData with XML data with multiple root nodes. Also make
1644 comparison for recordPacking case insensitive. Again, one server
1645 returns "XML" where others return "xml".
1647 For SRU responses allow Content-Type application/xml as well as text/xml.
1649 --- 3.0.4 2007/05/21
1651 Fixed bug in character set conversion of BER strings. Bug introduced
1654 --- 3.0.2 2007/05/08
1656 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1658 For OID class, use oid_class consistently.
1660 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1663 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1664 character set for bibliographic information interchange". By Giannis Kosmas.
1666 Added documentation on new OID API.
1668 --- 3.0.0 2007/05/02
1670 Changes to generic frontend server interface: added new member
1671 'query_charset' for bend_initrequest structure. A backend init handler
1672 should set this member to its native character set for query terms.
1673 When defined, the frontend server logic will announce this character set
1674 to a client if the negotiationModel bit is set by the client. All server
1675 implementors are encouraged to specify this. If a backend server does not
1676 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1678 Added CCL utility to remove terms (stop words) from resulting RPN
1679 tree. This is handled by functions with prefix ccl_stop_words_ .
1681 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1682 terms in RPN queries.
1684 Clean-up the CCL API. Moved some internal structures from ccl.h to
1685 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1686 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1687 This is replaced by ccl_parser_find_str which takes a string instead.
1689 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1690 libyaz.la is the core of YAZ except the generic frontend server and
1691 does not depend on POSIX threads anymore. libyaz_server.la is the
1692 generic frontend server facilities and uses POSIX thread functionality
1693 if available. The libyaz.la no longer depends on POSIX threads because
1694 the number of global structures is limited. NMEM no longer re-uses blocks
1695 between threads ; it simply free's memory immediately but allocates in
1696 "large" chunks as usual. We don't expect any performance penalties
1697 because of this. The yaz_log system is still using a global log_level so
1698 caution must be taken when modifying it with yaz_log_init_.. +
1699 yaz_log_mask_str. This, however, should not cause any trouble because
1700 these functions are called during initialization of application code
1701 anyway. `yaz-config --libs server` returns libs for server applications;
1702 `yaz-config --libs` returns libs for non-server applications.
1704 New OID database - with public definitions in oid_db.h. Removed old OID
1705 database including the head oid.h and definitions such as enum oid_value
1706 and struct oident. The new OID database uses the same string names as
1707 before but the 'protocol' is gone. There are now only two representations
1708 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1709 converts from string to OID; functions with prefix yaz_oid_to_string
1710 converts the other way.
1712 Change to emit_term() in CQL-to-PQF query translation: when a term has
1713 the /regexp relation modifier, do not process it for leading and
1714 trailing "^" and "*", which have quite different meanings in regular
1717 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1718 write handlers no longer carries a 'last' parameter. This will make
1719 yaz_iconv flush "less" characters. A flush is performed by call to
1720 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1722 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1723 removed, because function yaz_query_to_wrbuf does the same.
1725 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1726 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1728 Deprecated MARC utility functions removed.
1730 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1733 Branch split: YAZ_2_1_55_branch
1735 --- 2.1.54 2007/03/16
1737 Fix to ZOOM-C so that transparent reconnection is properly handled on
1738 connections that are in asynchronous mode.
1740 Fixed compilation on OpenBSD 4.0.
1742 Large strings in GRS-1 records are now properly displayed in yaz-client.
1744 Added character conversion support for "advancegreek"; based on patch from
1747 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1748 sequence is met. Before the error was not set so it would be unknown.
1750 Adjust yaz-marcdump MARC reader so that it skips until record separator
1753 --- 2.1.52 2007/03/07
1755 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1756 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1757 fd_set structure used as a bitmask for the FDs to be selected on.
1759 Using ACX_PTHREAD macro to check for POSIX threads.
1761 Fixed have-vsnprintf check.
1763 --- 2.1.50 2007/02/23
1765 Fixes for configure on BSD. Bug #900.
1767 Added snprintf/vsnprintf wrappers for systems that don't have
1768 limits (heavens forbid).
1770 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1771 created before all previous tasks were completed and removed from the
1772 task queue, the new task could be removed by a mistake.
1774 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1776 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1778 Fixed bug #832: Problem with MARC/charset in yaz-client.
1780 Fixed bug #668: save command line history for yaz-client.
1782 Fixed bug #830: pkg-config support.
1784 --- 2.1.48 2007/01/23
1786 Extended ZOOM result set options with two options that may be read by
1787 a client: resultSetStatus and presentStatus with values as specified for
1789 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1791 Fixed bug #827: Using SSL fails on Debian etch.
1793 Fixed bug #826: Weird looking chars for set of MARC records.
1795 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1796 that is treated as an ItemOrder with itemRequest being an XML document
1797 external. The value of "doc" is the content.
1799 Extended the GFS search facility. New member of bend_search_rr
1800 'estimated_hit_count' signals that hits is known to be an estmate
1801 (higher or lower than real hit count). New member 'partial_resultset'
1802 signals that the search was partial (hit count is lower or equal than
1803 real hit count). For Z39.50, the information is stored in resultSetStatus
1804 member of SearchResponse APDU. For SRU, the information is signalled
1805 via SRU diagnostic 59: "Result set created with valid partial results
1808 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1810 --- 2.1.46 2007/01/13
1812 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1814 Added ZOOM_connection_peek_event.
1816 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1817 the following new functions:
1818 ZOOM_event_nonblock, ZOOM_connection_process,
1819 ZOOM_connection_get_{socket,mask,timeout},
1820 ZOOM_connection_fire_event_{timeout,socket}.
1821 The existing blocking event handler, ZOOM_event, is a wrapper for the
1822 + blocking ZOOM_event_sys_{poll,select}.
1824 Implemented function ccl_xml_config which parses XML version of CCL
1825 configuration (bug #798).
1827 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1829 Added timings utility (yaz/timing.h)
1831 --- 2.1.44 2007/01/03
1833 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1836 Fixed bug #779: Rotation of apdu.log fails.
1838 Fixed for character set conversions:
1839 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1840 Honor G1 set in MARC-8 decoding.
1842 --- 2.1.42 2006/12/17
1844 Fixed bug #775: char conversion does not handle Alternative UTF-8
1847 Implemented function yaz_marc_read_line which parses MARC line format
1848 records. There is a wealth of formats out there. So far, this function
1849 reads line records produced by yaz_marc_write_line.
1851 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1852 more generic and easier to remember(!) options: -i format and -o format
1853 which specifies input format and output format respectively - where
1854 format is one of "marc", "marcxml", "line", "marcxchange".
1856 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1857 does not print anything except warnings for records.
1859 For yaz-marcdump, added support for MARC split into files (-s) with a given
1862 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1863 spec, at http://www.loc.gov/standards/sru/record-update/
1864 This has changed the binary layout of the following structs:
1865 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1866 bend_update_rr . Patch by Ko van der Sloot.
1868 Added GFS utility function bend_assoc_is_alive which returns 1 if
1869 association is still alive (client is connected); 0 otherwise (client
1870 closed connection). This allows busy servers to stop working for
1873 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1874 been a separate piece of software. This version of ziffy has been modified
1875 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1877 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1879 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1880 Client code may now interrogate options such as "init_opt_sort" to
1881 find out whether the server claims to support various options.
1883 --- 2.1.40 2006/11/27
1885 Added utilities yaz_{set,get}_esn to set/get element set name from
1888 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1889 of YAZ and has been so since YAZ 2.1.10.
1891 Implemented ZOOM_record_error which returns error information for
1892 record (surrogate diagnostic).
1894 --- 2.1.38 2006/10/31
1896 Updates for SRU Update by Ko van der Sloot:
1897 1. Changed name from "operation" to "action"
1898 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1899 versions in the code, marked as 'backward compatible'.
1900 3. Added diagnostics for SRU Update.
1902 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1904 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1906 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1908 For GFS, fixed problem with SRU diagnostic 'First record position out of
1909 range' being issued for 0 hits.
1911 zoomtst10 part of Windows Build.
1913 --- 2.1.36 2006/10/13
1915 Implemented yaz_filepath_comp which splits a path into file path
1916 components (required by Zebra 2.0.3+).
1918 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1919 BSD inspired license until now so this should not have any real impact on
1920 anybody. See http://www.opensource.org/licenses/bsd-license.php
1922 Fixed bug #687: Missing log lines.
1924 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1927 Fixed bug #689: SRU diagnostics to be added.
1929 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1930 whether a connection is idle (no more work do do).
1932 --- 2.1.34 2006/10/04
1934 Change type of optval from long to int for invocation of setsockopt with
1935 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1937 Added support for specifying the max log file size for the Generic
1938 Frontend Server. The size is given with option -r.
1940 --- 2.1.32 2006/09/21
1942 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1944 --- 2.1.30 2006/09/17
1946 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1949 Fixed bug in Generic Frontend Server that could cause a server to stop
1950 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1952 For the generic frontend server, the maximum record size is used as maximum
1953 size of incoming packages (SRU + Z39.50). The value until was previously
1954 only used in Z39.50 Init negotiation and, later, in a session controlled
1955 sizes of records returned. This is controlled using -k option. It can be
1956 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1958 --- 2.1.28 2006/09/04
1960 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1963 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1965 New option for yaz-marcdump -lpos=value which allows setting a portion
1966 of MARC header to a certain value.
1968 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1970 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1971 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1973 --- 2.1.26 2006/08/15
1975 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1978 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1980 --- 2.1.24 2006/08/08
1982 Fixed MARC ISO2709 encoding routines to deal with character set
1985 Minor changes to GFS logging. Database included in search request log
1988 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1989 cached/multiple records.
1991 Shared libraries are built by default on Unix+configure.
1993 Changed cql2pqf transformation to use a different evaluation order. The
1994 new order is: always, relation, structure, position, truncation, index
1995 and relationModifier. Old order was: always, relation, relationModifier,
1996 structure, index, position, truncation. Note that the the latter ones
1997 override former ones for identical attributes.. The new scheme means that
1998 it is possible to override any existing attribute with a relationModifier.
1999 And also that it is possible to override everything for the index rule
2000 (except the ones listed in relationModifier). No order is perfect but this
2001 one, we believe, covers more real cases.. The "always" should have been
2002 called "default", since the attributes there can be overridden with all
2005 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2006 compilation phase, but also for yaz-config --cflags output. This allows
2007 us to have public headers with Libxml2 stuff in them . It should also,
2008 eventually, make Libxml2 checks redundant in packages using YAZ, such
2011 --- 2.1.22 2006/06/15
2013 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2014 stored in uri, message and details.. Previously diagnostics were stored
2015 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2016 compatibility.. but he's probably the only one affected, so.
2018 Added support for CCL, compiled on the client side, in ZOOM-C. This
2019 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2020 input; the resulting query objects can be used for for searching with
2021 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2023 YAZ' configure searches for OpenSSL by default.
2025 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2026 SL_CTX_use_certificate_file. See
2027 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2028 for more info. Thanks to Ko van der Sloot.
2030 --- 2.1.20 2006/06/02
2032 Bug #600: SRU GET, POST support for yaz-client. Introduced
2033 command 'sru' which selects method SOAP/GET/POST.
2035 Allow missingValueAction to be specified for the sortspec string -
2036 function yaz_sort_spec. By default, the missing value action is null.
2037 Use ! to specify "abort". Use = followed by stringvalue to specify default
2040 Ensured that Present-handler (if defined) is called in GFS before any call to
2041 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2042 searchRetrieve requests.
2044 Documentation for YAZ is now based on the Docbook XML/XSLT using
2045 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2046 is no longer depending on jade/openjade or docbook-to-man scripts.
2047 PDF is no longer part of the distribution - but can optionally be
2048 made using DSSSL/jadetex or FOP.
2050 Added retrieval handling support in Generic Frontend Server to support
2051 conversion between MARC/XML as well as XSLTtransforms. See
2052 etc/yazgfs.xml for an example.
2054 Added Authentication support to Generic Frontend Server in SRU
2055 mode. Authentication using HTTP Basic is supported, as is the use
2056 of 'x-username' and 'x-password' parameters in the request itself.
2058 Added support for a new character set MARC8s identical to MARC8 except
2059 that it converts combined characters to single Unicode characters in the
2060 Latin-1 range (when possible).
2062 --- 2.1.18 2006/04/24
2064 ASN.1 compiler 0.4: generates brief Doxygen file header for
2065 generated .h/.c files.
2067 Utility yaz_iconv now supports conversion to MARC-8.
2069 New facilities for the MARC module. The reading - and writing of
2070 content are separate methods for the yaz_marc_t handle. The following
2071 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2072 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2073 format). Write functions have prefix yaz_marc_write_.. The existing
2074 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2075 available. Removed support for OAI-MARC and simplexml (not the
2076 simplexml from PHP5).
2078 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2079 to be returned for this connection.
2081 --- 2.1.16 2006/03/31
2083 Allow multiple languages and charsets to be specified with
2084 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2085 negcharset iso-8859-1,utf-8
2087 Translation of proximity nodes from CQL into PQF now works.
2089 Moved to automake 1.8, 1.9.
2091 Added function yaz_log_set_handler which allows a log handler to be
2092 installed. This handler will be called for all log messages. Output
2093 to file is also produced; but that can be disabled by passing NULL
2094 fname to yaz_log_init_file.
2096 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2098 For SRW (including GFS), accept application/soap+xml as content-type
2101 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2102 produces NO stylesheet reference even if a default stylesheet is specified
2105 --- 2.1.14 2006/03/14
2107 Updated Windows package to include yazd.dll + yazd.lib for the
2108 Development component.
2110 If the environment variable YAZ_LOG is set, then it is used as a
2111 string indicating the default level of logging to use if not
2112 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2113 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2114 used as before. So, for example, to omit warnings from YAZ logging,
2115 export YAZ_LOG=-warn
2117 cql_transform() now map structure and other attributes before indexes,
2118 so that index-specific structures and other attributes can override
2119 defaults. So now a combination of mapping specifications such as:
2121 index.dc.date = 1=date-modified 4=5
2122 does the right thing.
2124 cql_transform() now also respects the "always" mapping specification,
2125 which establishes an initial set of attributes to be used for all
2126 terms except where overridden by more specific attributes associated
2127 with the index, relation or modifier.
2129 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2130 which mode to use; one of "post", "get" or "soap" (SRW, default).
2132 Fixes for yaz_iconv routines: changed trie-based character set conversions
2133 to use only non-negative values for bit fields due to Sun's C compiler not
2134 supporting negative values.
2136 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2137 sequences where not read correctly. Fix by Rustam Usmanov.
2139 Updated win/makefile to use options, settings which makes things
2140 compile with VS C 2005.
2142 --- 2.1.12 2006/02/01
2144 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2146 In ZOOM socket code, use select instead of poll on MacOSX.
2148 ZOOM-C now support client-side compilation of CQL into RPN that is
2149 sent to the server, enabling CQL to be used against all Z39.50
2150 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2151 ZOOM_query object, and submit it using ZOOM_connection_search().
2152 The CQL-to-RPN translation uses a configuration file, the name of
2153 which must be specified in the Connection's "cqlfile" option.
2155 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2156 function, which takes as its start-term parameter a ZOOM_query object
2157 (which may have had either CQL or RPN set into it).
2160 --- 2.1.10 2005/11/29
2162 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2163 GFS to support this as well. Backend handler, bend_srw_update, does the
2164 update work. Code contributed by Ko van der Sloot.
2166 Allow retrieval of Search Result-1 information in ZOOM by the use of
2167 options that are attached to a result set. ZOOM documentation updated
2170 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2171 UTF-8 conversion. Patch by Raj Patel.
2173 Added option -m to GFS to control formatting of timestamps in log file.
2175 Added 'exit' as synonym for 'quit' in yaz-client
2177 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2178 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2179 for the new members. Patch by Ko van der Sloot.
2181 Added support for SRU POST. It is supported for content-type
2182 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2184 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2185 Instead make the library libyaz.la multi-threaded. Threading as a whole
2186 can still be disabled by configure option --disable-threads. Previosly,
2187 with older GLIBCs there were problems with MT libs under Apache. This
2188 has now been fixed a long time ago.
2190 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2193 CQL module modified to be case insensitive for relations/indexes/operations.
2195 Fixed bug in CQL transform code: incorrect value relationModifieder
2198 Added 'show all' command for yaz-client which retrieves all results
2201 Added new yaz-client, xmles, which takes a (private) OID and
2202 a document to be sent as an extended service request.
2204 Describe new yaz-client commands wait_response and set_auto_wait.
2206 Increase TCP/IP listener backlog from 3 (which I am guessing was
2207 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2208 that the socket will queue as many incoming connections as it's able
2209 to handle ongoing connections. In other words, it will never now
2210 refuse a connection that it would be able to handle merely because
2211 it's not got around to accepting() enough of the pending connections
2212 yet. This is the behaviour anyway under Linux, where the listen()
2213 argument is ignored; but not under BSD and on systems such as
2214 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2215 YAZ-based servers should now be uniform across operating systems in
2218 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2219 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2220 This allows yaz-marcdump to read large MARC batches (>2 GB).
2222 Modified all YAZ source files - except the source which is auto-generated
2223 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2226 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2227 corresponding to the existing *_setl() function. These allow option
2228 values containing arbitrary valuues.
2230 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2231 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2232 except that it returns an indicator of whether or not the sort
2233 criterion was accepted (0 for OK, -1 for invalid).
2235 --- 2.1.8 2005/06/07
2237 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2238 MARC output rather than returning "new" buffer.
2240 yaz-client warns about unknown init options.
2242 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2244 --- 2.1.6 2005/05/24
2246 Added support for SRW sort in Generic Frontend Server. Patch
2247 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2248 sortKeys - or NULL if none is provided.
2250 Fixed bug #307: It was impossible to specify indefinite/no timeout
2251 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2254 Added support for multiple languages and charsets to be specified in
2255 ZOOM. Each charset/language is separated by a blank. If negotiation is
2256 in effect in init-response, Option
2257 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2258 Code based on patch by Vasiliy Osadchuk.
2260 Fixed bug #306: infinite recursion that occurred when calling
2261 yaz_log_level_init as the first call (before other log level or
2264 Fixed bug in scan handling in front end server: if preferred-Position-In-
2265 Response was non-present, a NULL pointer referece was performed.
2267 --- 2.1.4 2005/04/26
2269 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2270 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2271 now defined for all those error codes. So instead of putting 109 in
2272 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2273 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2275 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2278 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2280 Program yaz-client now exits and produces an error message if multiple
2281 Z39.50 servers are specified on the command line (none or one allowed
2284 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2287 --- 2.1.2 2005/03/16
2289 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2291 Fixed bug #272: Preserve spacing for CCL terms.
2293 --- 2.1.0 2005/03/14
2295 Added support for virtual hosts and multiple backend servers for
2296 the YAZ frontend server. The configution is XML based and
2297 support specificition of CQL to RPN mappings and explain information.
2298 See section "Virtual Hosts" in the YAZ manual.
2300 Extended OPAC display utility. OPAC display utility renders
2301 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2302 to supplement yaz_marc_decode_wrbuf.
2304 Fixed a bug in MARC decoder that could caused it to crash for some
2305 invalid MARC records. More diagnostics and warnings where added in
2306 XML output (warnings, etc are stored in comments).
2308 --- 2.0.34 2005/02/08
2310 Fixes for UNIX domain sockets. Bug #261.
2312 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2314 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2315 Added yaz_marc_subfield_str which defines subfield lead string which is
2316 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2317 yaz_marc_endline_str which defines end of fields string used in
2318 YAZ_MARC_LINE format. Default string is newline.
2320 Experimental support for MarcXChange. This format can be produced
2321 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2322 http://www.bs.dk/standards/MarcXchange.xsd
2324 Added yaz-client commands scansize that sets maximum number of
2325 entries to be returned by scan.
2327 --- 2.0.32 2005/01/11
2329 Added support for SRW scan in yaz-client and Generic Frontend Server.
2331 * Added whereInList member to SRW Scan Term.
2333 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2335 Fixed NMEM system to return aligned blocks on the smallest boundaries
2336 that are suitably aligned for all possible types on the particular
2337 architecture YAZ is being built for.
2339 --- 2.0.30 2005/01/04
2341 Fixed numerious warnings that was issued with newer versions of GCC.
2343 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2344 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2347 Make YAZ Generic Frontend Server slightly faster.
2349 Enhance (and reduce) logging for Generic Frontend Server.
2351 Revert YAZ log system so that it flushes every write operation
2352 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2354 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2355 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2356 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2357 will effectively disable old definitions.
2359 --- 2.0.28 2004/11/09
2361 Added yaz_log_time_format which specifies log format using
2364 Added yaz_log_module_level which returns mask for a module. Value
2365 is non-zero mask a if module is enabled; zero if disabled.
2367 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2368 in include/yaz/cql.h.
2370 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2372 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2374 Fixed bug #172: RPM builds does not enable SSL.
2376 Doxyfile.in part of dist. Doxyfile generated by configure.
2378 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2379 are given and the corresponding component does not exist.
2381 Extend CCL documentation in YAZ reference. Describe r=r.
2383 --- 2.0.26 2004/10/01
2385 Fixed MARC->MARCXML conversion to properly deal with
2386 fields, subfields, indicators having non-ASCII characters.
2388 Fixed MARC->MARCXML conversion so that ASCII control characters
2389 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2392 Added YAZ GFS support for conversion from Z39.50 surrogate
2393 diagnostics to SRW surrogate diagnostics.
2395 Bug fix: YAZ GFS did not return schema in explainResponse.
2397 --- 2.0.25 2004/09/30
2399 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2400 now converts recordSchema to elementSetName as well as schema URI.
2402 Fixed bug in COMSTACK that prevented HTTP request packages from being
2405 --- 2.0.24 2004/09/29
2407 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2408 does not require white-space before and after the dash in a range, e.g.
2409 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2412 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2413 due to new GCC removing "redundant" code.
2415 Added yaz-client commands scanpos and scanstep that sets preferred
2416 position and step-size for scan.
2418 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2420 Added CCL utility ccl_qual_buf which parses one or more CCL
2421 spec lines in a buffer.
2423 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2424 of name and value - ignoring empty lines and comments.
2426 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2428 Added odr_get_element_path which returns current element path for an
2429 ODR handle. This utility is useful in error handling or user-defined
2432 Added ODR_PRINT utility odr_set_stream which is is a more generic
2433 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2434 to a write function and pointer to close function. The close function - if
2435 non-NULL - will be called during odr_destroy.
2437 Fixed bug in CCL parser where truncation char was not removed from
2438 right side when truncation=both was in effect.
2440 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2443 --- 2.0.23 2004/08/11
2445 Fix buffer overrun in CQL parser when dealing with proximity (%).
2447 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2448 to UTF-8/UCS conversion is now only based on codetables.xml.
2450 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2452 --- 2.0.22 2004/08/06
2454 Add support for more "commit changes" in ZOOM (uses Extended Services).
2456 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2459 Yet another small fix for configure of SSL.
2461 --- 2.0.21 2004/05/14
2463 Fix SSL libs for configure when --with-openssl=DIR is given.
2465 --- 2.0.20 2004/05/10
2467 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2469 SSL comstack now uses yaz.pem certificate file on server side
2470 by default. Certificate filename can be configured by calling
2471 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2473 Fix bug regarding multiple calls to ZOOM_connection_connect.
2475 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2477 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2478 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2480 ZOOM now allows inspection of X509 peer certificate for verification.
2481 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2483 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2484 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2485 as "modular" but it simplifies things.
2487 Added cs_get_peer_certificate to that returns peer X509 PEM.
2489 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2490 NULL if SSL is unavailable.
2492 Documentation about MARC decoding tools.
2494 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2496 --- 2.0.19 2004/03/30
2498 Rename CHANGELOG to NEWS to follow GNU style packing.
2500 Fix bug with missing initialization of member in init_diagnostics.
2501 This bug affects threaded version of GFS server.
2503 --- 2.0.18 2004/03/20
2505 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2508 Ensure zlib.dll is packed with Windows install.
2510 --- 2.0.17 2004/03/17
2512 Fix encoding of xsd:string to use text instead of CDATA.
2514 Fix endless loop in CQL parser with unbalanced ".
2516 Use a more compact way to store MARC-8 conversion tables.
2518 --- 2.0.16 2004/03/16 Debian only
2520 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2523 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2528 --- 2.0.15 2004/03/01
2530 Another fix for decoding of XML packed records.
2532 --- 2.0.14 2004/02/25
2534 Fixes for Chunked encoding. White space not ignored after length spec.
2536 Update NS and use default NS for SRW diagnostic elements.
2538 --- 2.0.13 2004/02/23
2540 Implement ZOOM_resultset_cache_reset which resets record cache.
2542 Implement ZOOM_resultset_sort which sorts a result set.
2544 Implement chunked HTTP transfer.
2546 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2548 --- 2.0.12 2004/02/16
2550 Added member 'schema' to bend_explain_rr structure so that backend
2551 can specify explain record identifier. Defaults to Zeerex 2.0.
2553 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2555 --- 2.0.11 2004/02/16
2557 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2560 Added init command for yaz-client which sends "extra" init request.
2562 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2563 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2565 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2567 Make ZOOM error code for "invalid query".
2569 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2571 --- 2.0.10 2004/02/05
2573 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2576 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2578 Added option -p <file> to make Generic Frontend Server to write PID file.
2580 Added option -D to put Generic Frontend Server in background on its own.
2582 Make ZOOM C recognize option "password". If unset, "pass" is used
2583 (for backwards compatibility).
2585 Fixed a bug in Generic Frontend Server that could make it crash if a
2586 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2589 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2590 Must be issued before open, in order to be in effect.
2592 --- 2.0.9-6 2004/01/12 Debian/Windows
2594 Make the SRU server more picky WRT unknown params, etc.
2596 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2598 New YAZ client command, options, that sets Z39.50 options.
2600 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2601 options from a string of tokens (one token for each option bit).
2603 Update SRW diagnostic code messages.
2605 --- 2.0.9-5 2004/01/07 Debian/Windows
2607 Handle user defined stylesheet for SRW/SRU.
2609 --- 2.0.9-4 2004/01/06 Debian/Windows
2611 Fix bug in decoding of Content-Length.
2613 --- 2.0.9-3 2004/01/06 Debian/Windows
2615 Fix a bug with decoding of XML packed records.
2617 --- 2.0.9-2 2004/01/05 Debian only
2619 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2621 Fix bug in SRW/SRU diagnostics decoding.
2623 --- 2.0.9 2004/01/05
2625 Fixed bug in Generic Frontend Server which could drop records exceeding
2626 preferred message size. Reported and fixed by Irina Dijour.
2628 Fixed calculation of package size for structured records in Generic
2629 Frontend Server. Reported and fixed by Irina Dijour.
2631 Fixed namespace for SRW/SRU diagnostics.
2633 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2635 --- 2.0.8 2003/12/22
2637 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2638 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2641 CQL changes to reflect recent changes to the specification:
2642 * Documentation talks about context sets instead of index sets.
2643 * Documentation talks about indexes instead of qualifiers.
2644 * The CQL-to-PQF transformer's configuration file now uses
2645 "index.set.name = <attributes>" instead of the old form
2646 "qualifier.set.name = <attributes>". (Both forms are still
2647 understood but the latter is deprecated.)
2648 * CQL terms with no explicit index specified are now interpreted as
2649 cql.serverChoice instead of srw.serverChoice (which of course
2650 behaves exactly the same.)
2652 --- 2.0.7 2003/12/16
2654 MARC conversion can now generate ISO2709 output in another
2655 character set. yaz-marcdump uses this facility if you invoke it
2658 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2659 functions from there can be used from C++.
2661 --- 2.0.6 2003/12/04
2663 Frontend server now transfers memory from decoded packages to stream
2666 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2667 references to show up.
2669 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2670 the ZOOM Abstract API. The older names for the same options are still
2671 also supported for the benefit of old applications.
2673 ZOOM-C supports "implementationId" and "implementationVersion" options
2674 to go along with "implementationName". These allow the user code to
2675 specify identification strings to be sent to servers.
2676 Add OID for the new ExtLite attribute set.
2678 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2679 as requested/supplid by Ere Maijala <ere@atp.fi>
2681 For generic frontend server, reverse the order of
2682 "toolkit-supplied / application-supplied" strings sent as implementationId,
2683 Name and Version. Also, remove the spaces around the slash. This brings
2684 the GFS in line with the behaviour of ZOOM-C on the client side.
2686 Add function ZOOM_scanset_display_term.
2688 yaz-client shows scan displayTerm if present.
2690 Utility yaz-iconv is now installed by default along with the man page
2693 Extend configure check for OpenSSL to use pkg-config where available (such
2696 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2697 server to specify uid/gid/mask for socket using the format
2698 unix:[user=uid,][group=gid,][umask=mask,]file=path
2699 If file= is omitted the existing format is assumed, e.g.
2701 in which case the mask is 0666 (rw for everybody).
2703 Major restructure of YAZ source. All source in libyaz is in src directory.
2704 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2705 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2707 Added man page for utility yaz-marcdump (used to be called marcdump).
2708 yaz-marcdump is installed by 'make install'.
2710 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2711 of incoming package failed.
2713 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2715 Change prototype of odr_perror: add const to message string.
2717 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2719 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2720 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2721 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2722 DNS lookup. There should not be any compatibility problems with this
2723 assuming that blocking=1 or 0 is used.
2725 Fix bad reference in UNIX comstack in function cs_addrstr.
2727 Fix for compilation on AIX.
2729 The generic front-end server (server/seshigh.c) now supports returning
2730 Init diagnostics to the client in User-information-field, in
2731 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2734 --- 2.0.4 2003/09/04
2736 Allow any CQL relation (not just all,any,exact,scr).
2738 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2739 that features the same UI.
2741 Implemented command update0 in YAZ client which is equivalent to
2742 update but uses old of Ext Update ASN.1.
2744 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2745 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2746 Previously no OID was used for this info.
2748 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2749 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2750 returns 'malformed search term' otherwise.
2752 SortResponse member resultCount now set to NULL in sort handler of
2755 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2758 Add three new utility functions for translating OIDs between various
2759 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2760 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2761 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2762 char *oid_to_dotstring(const int *oid, char *oidbuf);
2763 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2765 Reverted modifications for ES Update definition for z_IU0Update
2766 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2767 is back to YAZ 2.0.2.
2769 String value attributes for CCL parser.
2771 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2772 which their FirstSearch server returns in Init responses, sometimes
2773 carrying useful diagnostic information when Init fails. This has the
2774 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2775 "z39.50/oclcui.asn", where its definition is somewhat different from
2776 what OCLC document on their web-site, as required to interoperate with
2779 Support for anonymous authentication in yaz-client. Use the command
2782 * Fix the OID of the Index Data-local "admin" Extended Service from
2783 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2784 the 1000, which indicates a locally-defined OID, was a mistake.
2786 --- 2.0.3 2003/06/20
2788 Fix CCL directive @case handling so that it affects string match for
2789 both CCL keywords and qualifiers.
2791 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2792 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2793 Decoder has been updated with ASN.1 changes as listed in
2794 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2795 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2796 z_IUUpdate, remains unchanged.
2798 ZOOM_record_get may now return a record in a specific character set.
2799 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2800 "from" is the character set of record as returned by target. "to" is
2801 the character set to be returned. If omitted, "to" is UTF-8.
2803 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2805 New ODR utility, odr_getelement, which returns name of element for
2806 which encoding/decoding failed.
2808 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2809 in cases where a required element was omitted.
2811 Bug fix: some MARC8 sequences were not converted.
2813 New ZOOM option "step" which specifies number of records to be
2814 retrieved in one chunk. Used in conjunction with "start" and "count".
2816 SRW support for yaz-client. Use scheme http: to use it, e.g.
2819 yaz-client no longer does (un)intelligent character set conversions
2820 by default. Can be enabled with charset and marc_charset commands.
2822 xmalloc trace fix for 64-bit systems such as DEC alpha.
2824 Solaris 2.6 compile fix.
2826 New function, cql_strerror() translates SRW error codes, as returned
2827 by cql_transform_error(), into human-readable English strings. Used
2828 in yaz-client diagnostics when appropriate.
2830 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2831 converts it into a type-1 query which is sent to the server. This
2832 makes CQL available for use with all Z-servers, as opposed to the tiny
2833 minority that can handle CQL queries themselves.
2835 --- 2.0.2 2003/04/28
2837 New Debian package layout similar to the Redhat Package layout.
2839 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2840 and search result respectively.
2842 --- 2.0.1 2003/04/25
2844 Redhat package is now several packages: libyaz (runtime libraries),
2845 libyaz-devel (development and documentation, and yaz (utility programs).
2846 Package spec file by Morten Bogeskov.
2848 New member 'schema' in struct bend_fetch_rr which the name of requested
2849 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2850 handler MAY set this to reflect the schema of the returned record.
2852 New member 'display_term' in struct scan_entry. GFS now sets member entries
2853 and allocates scan entries to be filled by user scan handler. In previous
2854 version, entries member was allocated by the scan handler. That still works,
2855 but the GFS will ignore member display_term - assuming it was NOT set by
2856 the handler. The fact that the GFS now allocates the entries both allows
2857 for new members and makes a scan handler easier to write.
2859 Fix CQL lex buffer overflow.
2861 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2862 SRU default recordPacking is string.
2864 SRU protocol support for frontend server.
2866 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2868 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2870 Added scan for the ZOOM shell (zoomsh).
2874 * String Identifers for Schemas (Amendment 5).
2875 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2876 Old definition for schema
2877 Odr_oid *schema; /* OPT */
2882 Z_InternationalString *uri;
2883 #define Z_Schema_oid 1
2884 #define Z_Schema_uri 2
2887 * resultCount parameter to Sort Response (Amendment 1).
2888 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2890 Support for SRW 1.0 over HTTP. This is an optional feature and
2891 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2894 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2895 on the same port. SRW SearchRetrieveRequests are mapped
2896 to bend_init,bend_search,bend_fetch,bend_close.
2898 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2900 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2901 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2903 ZOOM connections are SRW based if schem http is used for hostname
2904 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2905 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2907 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2908 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2909 distance=n, order=true/false, relation=le, prox unit=word. If
2910 n is omitted, distance 1 is used.
2912 Fixed problem with C compiler include path in wrong order.
2914 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2915 on Solaris. Patch from Ko van der Sloot.
2917 New MARC decode API. All new functions operate on a yaz_marc_t
2918 handle. The most important new functions are: yaz_marc_create,
2919 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2920 decode and destroy respectively. Decoder can produce formats
2921 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2922 include/yaz/marcdisp.h.
2924 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2925 to UTF-8, UCS-32, wchar_t or Latin-1.
2927 * Prototypes for yaz_iconv_-functions moved to separate header
2928 include/yaz/yaz-iconv.h.
2930 Make a few private functions 'static' in unix.c. This prevents
2931 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2933 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2934 are set when Init Response is received.
2936 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2937 but returns diagnostic set as well.
2939 New function yaz_strerror which is a portable wrapper for
2940 strerror/strerror_r/GetLastMessage.
2942 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2943 is returned for MARC. If type is "oai", then OAI MARC is returned.
2945 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2948 --- 1.9.2 2002/11/26
2950 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2952 Fix bad race conditions on SIGTERM and terminate gracefully in
2955 Move retrieval (data1) module to Zebra since nobody seems to be
2958 Add GRS-1 render for ZOOM using same format as yaz-client.
2960 --- 1.9.1 2002/10/05
2962 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2964 Fix broken ESpec handling in data1 module.
2966 SGML reader parses comments and makes them part of the data1 tree.
2968 Added several type casts so that YAZ compiles as C++ code.
2970 ZOOM didn't handle PDU encoding failures properly.
2972 Added more Bib-1 diagnostics (approved extensions).
2974 GNU configure: better check for iconv.
2976 More portable use of accept, getpeername. Check for socklen_t. Use
2977 int/size_t if socklen_t is not defined.
2981 PQF parser rejects bad queries - including those with extra
2982 characters in them. PQF parser used to silently ignore that.
2983 Cleaner API for PQF added, which allows you to get detailed
2984 error information for bad queries (see yaz/pquery.h).
2986 Fixed bug in ZOOM_record_get for type "database".
2988 Implemented mini iconv library supporting conversions between
2989 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2991 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2993 --- 1.8.9 2002/08/20
2995 Fixed ZOOM C record cache so that preferredRecordSyntax and
2996 elementSetName is used to check for already fetched records.
2998 --- 1.8.8 2002/08/02
3000 Added three members in bend_initrequest structure to facilitate
3001 character set negotiation.
3003 Fixed a bug in frontend server that could cause indefinite
3004 loops under rare conditions.
3006 Revised character set utilities (charneg.h) so that encoding
3007 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3009 For PQF, directive @term <type> sets term type for Scan/Search.
3010 Here <type> is general, string, numeric, null. The term type
3011 is inherited - just like @attr.
3013 New call odr_set_charset that sets character set conversion for
3014 international-strings on a ODR stream. Prototype is:
3015 int odr_set_charset(ODR o, const char *to, const char *from);
3016 The InternationalString is still represented as C string in YAZ
3017 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3018 won't). On the protocol level, you can use any encoding.
3020 Support for UNIX sockets in ZOOM.
3022 Solaris recv sometimes returns errno == ENOENT. It is treated as
3023 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3025 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3026 both client and server. Code by Morten Bogeskov.
3028 --- 1.8.7 2002/05/22
3030 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3031 that they can be used directly from Visual Basic. You must recompile
3032 your windows APP if you're using ZOOM.
3034 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3035 Commands "lang" and "charset" sets language and character set respectively.
3036 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3037 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3039 Attributes from multiple CCL fields may be OR'ed rather than merged
3040 using directive "@field or". Fields are still merged by default -
3041 equivalent to "@field merge".
3043 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3046 Fixed bug in zget for parameter ExtendedServicesResponse.
3050 --- 1.8.6 2002/03/25
3052 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3054 Client displays USR.1:SearchResult-1 (hits per term).
3056 Additional Search Info for search in Generic Frontend Server.
3058 Fixed CCL parsing of "field=s".
3060 WIN32 installer - using the excellent NSIS software from nullsoft.
3062 Fixed CCL parsing of "field = - <number>".
3064 Added function yaz_marc_decode that decodes MARC for line mode
3065 display or XML (similar to that used by JZKit).
3067 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3068 Z39.50. But ISO/ILL was, however.
3070 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3071 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

3076 --- 1.8.5 2002/02/03
3078 New YAZ client features: Command completion and new commands:
3079 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3080 Code provided by Jacob Poulsen.
3082 New call oid_trav, that visits all registered OIDs via callback.
3084 Function ZOOM_record_get now returns const char pointer rather than
3085 void pointer. It saves a lot of type casts.
3087 For YAZ client, command "auth" now allows you to set authentication
3088 in IdPass style. It is enabled when three tokens are given - order
3089 is user, group and password.
3091 Fix memory leaks in MARC record handling for ZOOM.
3093 New option for YAZ client, -k <kilobytes> that sets
3094 maximum record size. Similar to -k option for generic frontend
3095 server and yaz-ztest.
3097 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3099 Prefix query parser reports "fail" when bad attribute set is given.
3101 Fix in MARC decoder. Proximity logging. Fix for attribute set
3102 in scan handler for server. Patches by Shigeru Ishida.
3104 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3107 Configure option --with-openssl=<dir> now works when a directory is
3108 specified. Patch provided by Morten Bogeskov.
3110 New option for YAZ client, -u <auth>, that sets authentication.
3112 ZOOM fix: error information was sometimes "missing", since error
3113 was cleared/reset too when it shouldn't.
3115 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3117 --- 1.8.4 2002/01/04
3119 Scan for ZOOM API. New object ZOOM_scanset. New functions
3120 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3121 ZOOM_scanset_destroy.
3123 New ZOOM function, ZOOM_connection_last_event, that returns type
3124 of last event (such as "receive data", "send data", "apdu received",
3127 New ZOOM option, schema, that specifies schema for retrieval.
3129 New CCL feature. Qualifiers can be aliases for one or more
3130 other qualifiers (if more than one is given, OR is used).
3132 ZOOM uses named result sets if target supports it.
3134 Two new YAZ client commands: . (dot, which sources a script of YAZ
3135 client commands), and ! (to execute shell command.). Implemented
3138 Working on Debian packages.
3140 --- 1.8.3 2001/11/19
3142 YAZ client enables named result sets only if target supports it.
3144 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3146 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3147 with key="host" to get same result.
3149 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3150 Function Z3950_resultset_record(s) returns references to records
3151 "owned" by resultset. To become owner use Z3950_record_clone.
3153 Function z_ext_record handles Extended Services. Thanks to
3156 --- 1.8.2 2001/11/12
3158 CCL Parser fix: ignore token comma when dealing with and-lists.
3160 Documentation updates for COMSTACK.
3162 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3163 Changed prototype Z3950_records. For some functions, int parameters
3164 were changed to size_t.
3166 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3169 New MARC decode/display function, marc_display_exl, which properly rejects
3170 non-ISO2709 records. YAZ client uses it.
3172 --- 1.8.1 2001/10/29
3174 Fix bug: local attribute set wasn't set correctly in PQF strings.
3178 * Old Z39.50 codecs no longer supported.
3180 Added ZOOM C binding. See http://zoom.z3950.org/
3182 Renamed states for COMSTACKs to avoid confusion with events.
3184 Implemented cs_look and proper cs_rcvconnect.
3186 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3188 Configure detects POSIX threads on OpenBSD.
3190 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3191 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3193 When error is returned from present handler, non-surrogate diagnostic
3194 is returned in present response (and fetch handler is no longer called).
3196 * Minor adjustments to pquery parser (PQF). Token characters may be
3197 escaped by using backslash (C-style).
3199 PQF parser allows string attribute values to be specified. For @attr,
3200 non-numeric characters after the equal-sign are treated as strings
3201 (e.g. @attr 9=title).
3203 CCL trunction character may be defined (@truncation in file)
3205 * function zget_ExtendedServicesRequest sets waitAction to
3206 waitIfPossible (was wait).
3208 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3211 CCL operator names may be set in field definition files (CCL_bibset).
3212 See ccl/bib1 for an example.
3214 Fixes in ASN.1 compiler for C++ compatibility.
3216 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3217 and "op_or" to avoid conflict with C++.
3219 Fixed problem with GNU readline detection on Redhat 7.0.
3221 Added step-size for Scan backend handler.
3223 Fixed bug that made the frontend server crash when no attribute
3224 set was specified for scan.
3226 Front-end server automatically switches to original working directory
3227 when installed as an NT service. Previously -w had to be specified to
3230 Added extended attributes for retrieval module (data1), so that data1
3231 records carry d1_readXML/SGML attributes. d1_read also supports
3232 null-data rules ( <tag/>)
3234 On UNIX when POSIX threads are available, a separate library libyazthread
3235 is created. Programmers should link with that library and the yaz library
3236 when using threads. The reason for the split was that some applications
3237 on Linux, such as Apache, doesn't work well when using shared objects that
3240 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3241 (or any frontend server) in SSL mode by specifying ssl: followed by
3242 address. Only tested on UNIX.
3244 Added feature for CCL module. Virtual structure s=al or s=ol generates
3245 and-list and or-list respectively instead of phrase search.
3249 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3250 log_mask_str. This was done to avoid name conflicts with other libraries
3251 (such as other PHP extensions).
3253 Added raw OID member for preferred record syntax (request_format_raw)
3254 and returned record syntax (output_format_raw) for backend fetch method.
3256 Config file yaz-config now accepts options so that it returns specific
3257 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3259 Shared library support for UNIX using GNU libtool.
3261 * Modified backend interface. Request/Response struct's replaced by
3262 one read/write C struct. For example bend_fetchrequest and
3263 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3264 Every handler - even search has to be registered in bend_init
3265 handler. This means that the YAZ library no longer refers to
3266 external functions and it makes it possible to make the whole
3267 thing a single DLL/SO.
3269 Added Segment handler for backend server.
3271 Added Zmbol/Zebra administrative functions to YAZ client.
3273 Threaded frontend server on UNIX (when POSIX Threads are available).
3274 Starting the server with option -T enables multi-threading.
3278 Added configure option --enable-comp/disable-comp to control use
3279 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3280 located in sub directory asn.
3282 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3283 in ${exec_prefix}/bin along with the other programs yaz-client and
3286 GNU automake used to maintain makefiles.
3288 Added several OID's.
3290 Changed retrieval module so that we can load records with no abstract
3291 syntax defined. Tagpaths in these records are fully composed of string
3294 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3298 On UNIX, the generated makefile now supports a proper 'make install'.
3299 The prefix can be set via GNU configure to set the install location
3300 (default is /usr/local).
3302 * YAZ programs client and ztest were renamed to yaz-client and
3303 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3304 locations, such as /usr/bin,/usr/local/bin,etc.
3306 * YAZ Header files were moved from include to include/yaz. YAZ Header
3307 files are referred to as include <yaz/log.h> rather than <log.h>.
3308 The YAZ include path (-I ..) is therefore the same as before. Programmers
3309 should update their #include statements or use -Ipath/include/yaz
3310 instead. The main motivation for doing this change is that YAZ header files
3311 can be installed in "standard" locations /usr/include,/usr/local/include
3312 without introducing conflicts, since ALL YAZ header files are stored
3313 in subdirectory yaz (under /usr/include for example).
3315 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3316 rather than project/workspace files. We switched because project files
3317 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3320 Changed name of logging function, logf, to yaz_log, to prevent name
3321 clash with some math-log functions. The YAZ header log.h defines logf
3322 to yaz_log (#define) so there should be no incompatibilities by this
3325 Added bend_start/bend_stop handlers for server. These handler are
3326 called on start/stop of server. For windows they are called whenever
3327 a service is started/stopped.
3329 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3330 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3331 in util/yc.tcl. The auto-generated C code structures are, in a few
3332 cases, incompatible with the old decoders. There are differences in the
3333 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3334 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3335 The preprocessor variable ASN_COMPILED is defined when the compiled
3336 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3337 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3338 wish to use the old encoders/decoders you can specify --disable-yc
3341 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3342 version so that it supports both new - and old version of DB Update
3344 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3345 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3346 change. The name parameter can be set to 0 in which no name is specified
3347 for the construction. The macros odr_implicit and odr_explicit sets name
3348 parameter to zero for the construction involved. New macros
3349 odr_implicit_tag and odr_explicit_tag are similar to the others,
3350 except that a name parameter is added. For programmers' that don't use
3351 ODR they probably only need to change the call to z_APDU and z_External.
3353 Added access control facility by interfacing the TCP wrapper library.
3354 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3355 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3356 name of the daemon and enables the access control as specified in
3357 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3359 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3360 den Dool <H.M.vdnDool@kub.nl>.
3362 Added reference ID parameter to most functions in server API - refer
3363 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3365 Changed name of ccl library to libccl.a (was ccl.a).
3367 Fixed bug in decoder for Explain (Category TargetInfo).
3369 Added support for GNU readline in client. Thanks to Jacob Poulsen
3370 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3372 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3373 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3374 IMPLEMENTATION! This change was made to the development version before
3375 the ZIG decided to retract the amendment. If any users MUST be
3376 compatible with the original Update definition, PLEASE CONTACT US, and
3377 we will include a separate definition corresponding to the old Update
3378 ES. Note that because of the change to the ASN.1 of the
3379 TaskPackageRecordStructure we cannot define a single structure that
3380 will support both versions.
3382 * Added const modifier to buffer parameter for some ODR/BER encoding
3383 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3384 completeWAIS, odr_dumpBER.
3386 Fixed bug in client.c which caused a crash when a scanResponse didn't
3387 contain positionOfTerm.
3389 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3390 * will cause an error in a client if a non-YAZ target sends both a
3391 * list of Scan entries and non-surrogate diagnostics.
3393 Retrieval module enhancements. Tag sets may be typed in the reference
3394 to it. From the .abs-file the "tagset" directive takes a third optional
3395 integer type for the tag set referenced. From a .tag-file the "include"
3396 directive takes a third optional type as well. The old "type" directive
3397 in the tag set itself is still recognized but acts as the default type
3400 Backend interface change. Individual Scan terms returned from bend_scan
3401 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3402 in include/backend.h.
3404 Retrieval module enhancements. Multiple tag sets and attribute sets may
3405 be specified in abstract syntax specs. Revised the error/warning for
3406 logging messages reported by the retrieval module when reading the
3409 Object Identifier system (oid_..) changed. The API is backwards
3410 compatible but the oid-routines now allocates new OID's when needed.
3411 Raw OID's may be specified in oid_getvalbyname.
3413 YAZ now uses GNU configure to generate Makefile(s).
3415 * Minor changes in some of the member names of DeleteResultSetRequest and
3416 DeleteResultSetResponse. See include/proto.h.
3418 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3419 and added member 'languages' in TargetInfo (which was missing).
3421 Changed the way attribute sets are handled in the retrieval
3422 module. These are now cached, just like the abstract syntaxes
3425 Changed YAZ so that it links with compiled ASN.1.
3427 Added Explain-schema definitions and mapping routines. The following
3428 Explain categories have been implemented: AttributeDetails,
3429 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3431 Fixed minor bug in Windows version of Server Library.
3433 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3435 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3437 Added EXTERNAL: UNIverse Resource Report (non-standard).
3439 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3440 ENUMERATED and SET OF.
3442 * Added 'const' to some of the char pointer arguments for the
3443 functions, data1_read_node, data1_getelementbytagname,
3444 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3447 Fixed bug in data1_insert_taggeddata - the last_child member of
3448 parent wasn't initialised.
3450 * Changed data1_read_record and data1_read_node so that the supplied
3451 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3452 doesn't refer to any parts of the "SGML"-buffer.
3454 Fixed bug in server library (Windows version of statserv_remove).
3456 * Changed code so that it compiles as C++. The type definition
3457 of Odr_fun which is a member of Odr_arm was changed. The result is,
3458 that an explicit typecast is needed for the fun pointer when
3459 using Odr_arm - as in:
3460 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3462 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3464 Implemented the new structured date and time definition as approved
3465 by the ZIG. Added schemaId element to the specificTag in Espec-1
3466 (also approved at the last ZIG). Thanks to RVDM.
3468 Added some Object identifiers (RVDM).
3470 Changed the Update Extended Service (RVDM).
3472 Added command "refid" to client which specifies referenceId for
3473 the following requests.
3475 Implemented extended service handling for server. See ztest.c
3476 for an example as well as backend.h. New handlers are registerd
3477 in the Init handler.
3479 * Changed interface for sort in server.
3481 Added new members to statserv_options_block. It allows a server
3482 to read options from another source than just the command line. Thanks
3483 to Charles Woodfield.
3485 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3486 renamed to zboolean. Some C++ compilers complained about the name.
3488 Minor changes to gils.abs. Added index 's' (sort) on title
3489 and date/time-last-modified.
3491 --- 1.4pl2 1998/1/30
3493 Fixed bug in server library regarding inetd mode (-i). This bug
3494 was introduced by release 1.4.
3496 --- 1.4pl1 1998/1/29
3498 Added sort facility in client and backend server interface.
3500 Fixed problem with dependencies in Makefile(s).
3502 Fixed bugs for encoders/decoders of extended services and
3505 Implemented sub-tree feature for schemas. Sub-trees are
3506 referenced in *.abs-files. See explain.abs for an example
3507 of the use of this feature.
3509 Modified bib1.att; local attributes for ANY didn't include
3510 ANY itself (only affects use of the retrieval module).
3512 Fixed bug in plain SGML reader in function data1_read_node:
3513 tags with prefix "var" was incorrectly interpreted as variants.
3515 Added feature "sub-schemas" to enable references to - and definitions
3516 of - group of elements.
3518 * Removed member parent from type data1_element (in data1.h).
3520 Implemented function odr_nullval() that returns the value of
3523 * Removed member num_children from data1_node (in data1.h).
3525 Made NT service interface part of the server library. The
3526 function statserv_main uses the NT service when required and
3527 calls the statserv_start / statserv_close routines.
3529 Routine zget_SearchRequest and zget_PresentRequest fills
3530 resultSetName/Id member with "default" instead of "Default".
3532 Fixed memory leak in server. Request queue member wasn't freed.
3534 Fixed nmem_exit so that memory is freed.
3538 Revised the CCL parser utility to be thread safe.
3540 Added function, oid_ent_to_oid, to replace the function
3541 oid_getoidbyent, which is not thread safe.
3543 * Added nmem_init and nmem_exit to initialize and release
3544 NMEM resources. Function nmem_init should be called once in the
3545 initial thread before NMEM/ODR is used. statserv.c and client.c
3546 have been changed accordingly. The change was necessary to make
3547 NMEM thread safe. The NMEM memory pool is shared amongst threads
3548 in a process. Unix-based applications will still work fine without
3551 Added NT Services interface for the the Z39.50 (statserv) Server.
3552 Refer to the ztest.c source on the usage.
3554 Windows 95/NT port using MSVC5.0. Project files are included in the
3557 * Defined new 'global' handle for the retrieval (data1) system. The
3558 new handled, data1_handle, describes the state of the data1 system.
3559 This handle is passed as first argument to virtually all
3560 data1 related routines. The functions data1_create and data1_destroy
3561 creates and destroys a data1 handle respectively.
3563 Added ODR encode stream member to all backend request structures
3564 init, search, scan etc. This stream should be used to allocate all
3565 memory used for the response when thread safe operation is needed.
3567 Changed the comstack utility, cs_addstr, to be thread safe. The
3568 returned hostname string returned by the function is now part the
3571 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3572 function. The cs_straddr takes a COMSTACK handle as argument, so this
3573 function must be used after cs_create and before bind/connect.
3574 This function is thread safe.
3576 Moved test server to 'ztest' directory - generic server code still
3577 in 'server' directory.
3579 Made prefix query (pquery.c) utility thread safe.
3581 Added new function modifier YAZ_EXPORT to 'export' public DLL
3582 functions when using windows (see include/yconfig.h).
3584 Added definitions to the OID database (util/oid.c) (RVDM).
3586 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3588 Added call to ccl_rpn_delete in client program.
3590 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3591 release of RPN structure.
3593 Added support for C++, headers uses extern "C" for public definitions.
3594 With input from RVDM.
3596 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3597 Thanks to Ronald van der Meer (RVDM).
3599 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3601 Added support for private extensions to the OID database
3602 (oid_setprivateoids()). Thanks to RVDM.
3604 Added optional, physical ANY (key replication)
3606 Fixed null-reference problem in GRS-1 output filter.
3608 Proximity operator added to Prefix Query Format (PQF).
3610 In test client command "base" accepts multiple databases.
3612 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3616 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3618 Smallish bug-fixes in the new encoders/decoders (explain).
3620 Bug fixed in DeleteRequest.
3622 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3624 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3626 Added SOIF syntax (using private OID for now) to retrieval module and client.
3628 Added Update extended service.
3630 Added SearchResult-1 additional info structure.
3632 Added optional CCL (ISO8777) interpreter as separate module. Available
3635 --- 1.2 1996/6/10 (1st anniversary release)
3637 Added Summary record syntax. Lightly tested.
3639 Added OPAC record syntax. Untested.
3641 Added ResourceReport service encoders/decoders. Untested.
3643 Fixed bug in z_Unit - wrong tagging on unitSystem.
3645 Fixed bug in the DiagRecs decoder.
3647 Added options for max PDU size and session timeout to frontend-server.
3649 Added documentation of query-language parsers and other supporting utilities.
3651 [frontend-server] Added Attribute set to the bend_scanrequest API.
3653 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3654 surrogate diagnostics were generated.
3656 [retrieval] Allow multiple local values for attribute.
3658 [retrieval] Allow multiple attributes per element in .abs files. index type.
3660 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3662 --- 1.1pl2 1996/4/10
3664 Minor changes, mostly specific to Zebra's requirements (retrieval)
3668 Repaired bug in frontend server when running multiple listening
3669 endpoints in dynamic mode.
3671 z_External() now won't break if a known, ASN.1 value comes encapsulated
3672 in an octet-string. The value will pass through unmodified in an Odr_oct.
3674 Added a bit of code to the demo client to decode & display
3675 ASN.1-structured records represented in the octet-aligned branch of
3676 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3678 Added z_ext_getentbyref() to the ASN module. Doc updated.
3680 * Completed the SCAN definition in the ASN module. This may break SCAN
3681 code based on older YAZ-versions at compile-time. The fix is easy -
3684 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3685 under the SCAN definition. Remember to initialize this, server-people.
3687 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3688 that this does not extend to ODR and ASN.
3690 Comstack allows insertion of established socket (primarily for
3691 inetd-operation of servers). Doc updated.
3693 Front-end server can now start from the inetd in TCP mode. Doc
3696 --- 1.0pl4 1996/1/24
3700 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3701 the rank and record number.
3703 Adjustments to the frontend server.
3705 Fixed diagnostic BER dumper. It ignored the file argument.
3709 Various changes to retrieval module.
3711 Changed the union discriminators of the protocol files from enums to
3712 ints paired with #defines.
3714 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3717 *Changed operator in the RPN structure to 'roperator', again to avoid a
3720 Fixed problems in Explain decoders/encoders.
3722 --- 1.0pl2 1995/12/6
3724 Memory bug in log module fixed.
3726 --- 1.0pl1 1995/12/5
3728 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3730 Bug in Explain DatabaseInfo module fixed.
3732 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3736 The shift to v1.0 signals that we now consider the *core* functionality
3737 of YAZ reasonably stable (the core being more or less equivalent to
3738 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3739 tested (Explain not at all - though that will happen soonish).
3741 Minor changes to code to support Windows port.
3743 Various minor changes after we're getting to use GRS-1 & co. more.
3745 Added Espec-1 format.
3747 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3748 of the protocol and it cannot be selected when encoding (maps into 'string'
3749 when decoding). Needed to talk to some servers.
3751 Demo client can request simple element set names.
3753 Added Diagnostic Format encoders/decoders.
3755 Added simple Close handling to frontend server (no hooks for resource
3756 reporting yet), and demonstration client.
3758 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3760 --- 1.0b3 1995/08/24
3762 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3763 handled incorrectly when records were requested in the searchResponse. This
3764 will only affect you if you use the frontend-server.
3766 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3767 Test-client will ask for and print GRS1. Ztest will return dummy records
3770 Added Explain encoders/decoders to the service-level API. Untested.
3772 Added Extended Services: Item Order encoders and decoders to the Service-
3773 level API. Untested. We could use a recent copy of the pertinent bits
3774 of the ILL protocol to add those bits.
3776 Added diagnostic format 1 encoders/decoders to the service-level API.
3779 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3780 odr_cons.c, which causes a more correct output.
3782 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3783 was always set to 0 when no records were requested in the searchRequest.
3785 * Added better external-handling. This shouldn't harm old code that
3786 *encodes* externals. It can break code that looks for a
3787 'single-ASN1-type' representation, since those types that are known
3788 are now decoded immediately. Look at the SUTRS sample code in
3789 seshigh.c and client.c. Documentation updated.
3791 Handling of structured records in bend_fetchresponse. Length -1 marks
3792 structured record, type is deduced from format field.
3794 --- 1.0b2 1995/06/27
3795 Fairly quick maintenance release to add SUTRS support.
3797 Fixed handling of SUTRS records in the demonstration client.
3799 * Added format field to the bend_fetchrequest and bend_fetchresponce
3800 structures of the backend API (frontend server). When the record is
3801 returned, the value of the format field is mapped to an OID. The
3802 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3803 of the record. The special value VAL_NONE in the bend_request means
3804 that no specific format was requested by the client. Documentation
3805 updated accordingly. Test server (ztest) will return a fixed dummy
3806 SUTRS record if your client requests SUTRS.
3808 Documentation updated accordingly.
3810 You can now set external libraries and RANLIB support in the top-level
3814 First public release.
