3 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
6 Make cs_parse_host public.A
8 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
9 introduced in YAZ 5.0.6.
13 Fix buffer corruption for yaz-ztest record fetch.
17 Allow yaz-ztest to return user-defined records (one record per file).
18 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
20 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
21 Use the stream write instead of odr_printf which has a 4K tmp buffer.
23 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
27 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
28 can read and write this format. For record format JSON, yaz-ztest returns
31 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
32 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
36 Improve error reporting for ICU chains YAZ-707
37 Report config element+rule when ICU status is "failure".
39 ZOOM: stop fetching if present response has no records YAZ-710
40 Some targets return less records than their hit count would suggest.
41 This prevents ZOOM from continuing to fetch records if any present
42 response has 0 records in the response.
44 Ensure that GFS calls exit if any listener fails YAZ-710
45 Before, if XML config was in use, it would start the default
50 yaz-ztest: -V shows version (like yaz-client -V)
52 New iconv encoding: danmarc YAZ-692
54 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
56 daemon: only wait for immediate child rather than all children. YAZ-704
58 yaz-client: fix setting of SRU record schema. If scheme was unset, it
59 could lead to invalid memory reference.
63 yaz-ztest returns schema for MARCXML test records. SRU require that
64 recordSchema for records.
66 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
67 instead of non-surrogate diagnostic. This is a per-record failure.
69 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
70 may refer to multiple listeners now. Attribute listenref is a comma separated
73 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
74 option is given for GFS, the dirname of filename (for -f) is used
75 as prefix for options such as cql2rpn, ccl2rpn, etc.
77 Content-Type charset fixes YAZ-701 . Do not inspect charset in
78 Content-Type header for SOAP when decoding SRU. The payload (XML)
79 itself tells what encoding it is. In response, never supply encoding
80 in Content-Type. The response payload (XML) tells what it is (with no
81 encoding in XML it's UTF-8).
83 HTTP decoding: allow blanks in URL paths YAZ-700
87 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
88 and facets. Ensure recordData and recordSchema are always present in
89 record element, because they are required.
91 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
94 Simplify in a lot of places using odr_strdupn.
96 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
100 Increase various buffers in GFS's statserv_options_block
101 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
102 This change makes many type-casts redundant, and, thus simplifies code.
104 Remove last bits of WAIS support.
106 Remove member 'size' from Odr_oct.
108 Slim down the public part of 'struct odr'. Most elements are not part
109 of struct Odr_private.
111 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
112 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
113 In particular facets are supported in both client - and server side.
114 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
115 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
116 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
117 both request/response). This is what a search handler in the GFS
118 will see (regardless of whether operating in SRU mode or Z39.50).
120 Changes to the srw.h (SRU/Solr) definitions include:
121 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
122 (char*), which replace union query and query_type (int). This is because
123 SRU 2.0 supports a queryType parameter. This also means that, to carry
124 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
125 x-pquery=PQFstring (extention parameter). The extension parameter
127 - New element, packing, that has information about SRU
128 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
130 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
132 New element, packing, in Z_SRW_explainRequest.
134 New elements in Z_SRW_scanRequest, queryType and scanClause.
135 These replace query_type and scanClase untion. This is similar to what
138 --- 4.2.69 2013/10/01
140 GFS: log when closing down - at least SIGTERM YAZ-684
141 Also change formatting WRT PID logging a bit.
143 Improve display of MARC records with multi-byte subfield IDs YAZ-695
144 In some rare cases subfield identifiers are multi-byte characters.
145 This will try to deterime length of those and split accordingly.
146 This affects display in line mode as MARCXML/MarcXchange. The encoding
147 of ISO2709 is the same.
149 Change inp argument to const for yaz_read_UTF8_char.
151 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
153 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
155 Better check of marc leader info YAZ-691
156 Problem is that some systems generate MARCXML/MarcXchange with
157 funny headers. These will not work if encoded as ISO2709.
158 Some tests produce new output, due to updated warning messages
160 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
162 yaz-client: display MAB records YAZ-689.
163 Thanks for Heiko Jansen for this patch.
165 New utility z_get_HTTP_Response_server which allows both HTTP server name
166 and HTTP server URL to be given in response.
168 Debian: do not depend on obs tcl8.3.
170 Debian: do not depend on obs libicu36-dev.
172 --- 4.2.68 2013/09/23
174 GFS: pass additionalSearchInfo to search memeber search_input if
175 given. Otherwise pass otherInfo. Request for facets and other search
176 related things will be passed there in future versions of YAZ.
178 New ZOOM setting, authenticationMode, which allows authentication
179 paramters to be encoded in the URL rather than via HTTP Basic auth.
182 rpn2solr: fix nested AND/OR handling. YAZ-685
184 Add comparison routines for some Z-types, such as NamePlusRecord,
185 RPNQuery, Query, RecordComposition and OtherInformation.
187 --- 4.2.67 2013/09/19
189 Don't decode MAB as MARC. Just like we don't attempt to decode
190 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
192 CCL: allow quoted terms for date ranges. YAZ-681
194 Introduce ccl_parser_qual_search. This function makes old function
195 ccl_qual_search, from YAZ 2, available again.
197 Add yaz_facet_list_to_wrbuf. YAZ-683
199 --- 4.2.66 2013/09/11
201 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
202 schema was given for search. YAZ-675
204 Add Solr date range searches. YAZ-621
206 --- 4.2.65 2013/08/22
208 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
210 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
212 ISO2709/MARC parse most octet aligned records; not just those that
213 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
214 MARC parse more records instead of just dumping as is. YAZ-670
216 ZOOM: proper caching for variations of record schema. YAZ-671
218 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
220 --- 4.2.63 2013/07/17
224 --- 4.2.62 2013/07/11
226 New utility z_get_HTTP_Response_details - an extended version of
229 New utility yaz_url_get_error which returns error message of last
230 failed yaz_url_exec call.
232 yaz-url and url functions: allow max HTTP redirects to be controlled.
234 New functions yaz_file_glob2, yaz_xml_include_glob.
235 These functions takes a flags parameter, which, for now only controls
236 whether to fail inclusion of a non-existing file (without glob
237 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
239 --- 4.2.61 2013/06/20
241 For MARC XML parsing, allow record without leader. A fake/default leader
242 is inserted and a warning is tagged with the record.
244 ICU: fix leak in in icu_iter_get_org_info.
246 --- 4.2.60 2013/06/14
248 ICU: fix bug in icu_iter_get_org_info (un-init variable).
250 --- 4.2.59 2013/06/11
252 Implement z_HTTP_header_remove.
254 --- 4.2.58 2013/06/11
256 ICU: Disallow 0 ptrs for some ICU string utilities.
258 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
259 returns original tokens (before normalization).
261 CCL: avoid z39.58/regex truncation when not needed. Apply only the
262 conversion of those masks, when absolutely necessary.
264 CCL: configurable masking character - @mask. Default masking character
267 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
268 full response anyway, so a Transfer-Encoding header will obstruct the
271 --- 4.2.57 2013/05/15
273 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
274 picking a socket. Problem is that some systems has IPV6 support, but
275 we can't create sockets for them, so we pick AF_UNSPEC first.
277 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
278 use content_len to determine resulting Content-Length in HTTP response
279 and NOT Content-Length supplied in headers by user.
281 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
282 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
284 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
287 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
288 with big endian and unsigned char (by default).
290 --- 4.2.56 2013/04/26
292 Fix yaz-client connect (crash in 4.2.55).
294 --- 4.2.55 2013/04/26
296 Fix proxy/host problem for ZOOM that could occur if unix sockets
299 New Debian package libyaz4-dbg.
301 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
302 differently in tcpip_close.
304 --- 4.2.54 2013/04/17
306 Windows installer of YAZ includes YAZ4J as a component.
308 CQL: allow "extra terms" again, by default. Thus, the CQL parser
309 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
310 and earlier. CQL parser may operate in strict mode where queries
311 not conforming to the standard BNF are rejected (syntax error).
312 Whether the CQL parser operates in strict mode is controlled with
313 cql_parser_strict . Strict mode enabled with option -S for utilities
314 cql2pqf and cql2xcql .
316 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
318 --- 4.2.53 2013/04/10
320 New charset, MARC-8c, which is like MARC-8 but allows control characters
321 0x01 through 0x1F, except ESC to be passed through verbatim.
323 Fix a problem with duplicate sub field character in MARC output. Problem
324 happened only when output was MARC-8 encoded.
326 --- 4.2.52 2013/04/03
328 yaz-ztest: Use hash for fake hit count. Before, random number was used.
329 This is problematic for unit tests using yaz-ztest. This patch also makes
330 a hash for CQL queries. For RPN, any term with a leading digit will be
331 treated as pseudu hit count (to force any particular hit count by a client).
333 yaz-ztest: return unique MARC dummy records. Beyond record offset
334 24, the author surname is patched with offset to make all records
337 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
338 on system wide default (/proc/sys/net/ipv6/bindv6only).
339 @4 binds to IPV4 only. @6 binds to IPV6 only.
341 Update CQL API documentation a bit
343 CQL: don't accept extra terms for queries. Makes the CQL parser
344 stricly conformant to the standard.
346 --- 4.2.51 2013/02/12
348 GFS: scan handler gets extra_args from request and may return extra
349 response data . That's for SRU only.
351 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
353 --- 4.2.50 2013/01/30
355 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
357 OPACXML: sync spelling of availabilityDate in XML to that of Schema
358 opaxxml.xsd. The schema had the correct spelling of this member always.
359 The ASN.1 was mis-spelled and still is (API change) - we are
360 not changing this. However, the OPAC to XML conversion had yet
363 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
366 New function, z_ext_record_oid_nmem, which is similar to
367 z_ext_record_oid but takes NMEM rather than ODR
369 --- 4.2.49 2013/01/18
371 ICU: New conversion element 'join' which joins tokens into one
372 with a custom character given by rule attribute.
374 --- 4.2.48 2013/01/10
376 New GFS search member: present_number. This is a hint to the
377 search handler how many records are going to be fetched immediately
378 following search. There's no guarantee that it's going to be the case,
379 since it depends on hit count (for Z39.50 piggyback) and whether errors
382 Make a few functions static (private). The functions getbyte_stream,
383 ungetbyte_stream and yaz_gets are now private. They were never declared
386 yaz-marcdump: exit(5) for serious decoding errors
388 ISO2709 decoding: be more picky WRT header
390 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
391 was only used as to indicate that next-result-set-position should be
393 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
394 Based on patch from Ashley Sanders.
396 Make some functions static/private in PQF parsing. Those functions were
397 never declared in a public header and so should not be in use by
398 applications based on YAZ.
400 --- 4.2.47 2012/11/23
402 ZOOM: special options to control APDU logging.
403 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
404 logging of APDUs until "saveAPDU" option is set again. If logging is
405 already enabled the effect is that current APDU buffer is cleared.
406 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
407 logging (default behavior on new connection).
408 The APDUs sent/received can be obtained by using
409 Using ZOOM_connection_option_get(c, "APDU") or
410 ZOOM_connection_option_getl(c, "APDU", &l).
412 GFS: relay implementation_version from backend
413 From 3.0.40 and later, implementation_version from backend was
414 not used in init response at all.
416 --- 4.2.46 2012/11/15
418 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
419 mode at all. Probably never did.
421 Make a new version of ztest.pem that, at least, is not expired.
423 --- 4.2.45 2012/11/13
425 Fix description of CCL directive 'case'.
427 More tight checking of form arguments (yaz_uri_to_array). Makes
428 YAZ better at rejecting big and/or bad POSTs.
430 SRU decoding does not report more than up to 10 invalid arguments.
432 rpn2cql: less quotes in generated terms. Semantics unchanged, but
433 it's prettier this way.
435 --- 4.2.44 2012/10/25
437 New utility yaz_decode_init_diag. Defined in proto.h.
439 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
440 given for unix local socket.
441 The COMSTACK string for doing so is:
444 unix:/myfile:tcp:localhost:9999/mybase
445 unix:/myfile:localhost:9999/mybase
446 unix:/myfile:http://fakehost/mybase
448 debian: Use dpkg-buildflags in build process.
450 --- 4.2.43 2012/10/19
452 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
453 global's SRU service uses a recordPosition scheme starting from zero.
454 First record's position should be one
455 according to the standard.
457 --- 4.2.42 2012/10/18
459 Allow more namespaces for SRU. This is to allow, for example, an
460 incorrect namespace returned from server
461 http://services.igi-global.com/sru .
463 Minor fixes for compilation on Windows.
465 --- 4.2.41 2012/10/11
467 daemon: log total number of bad signals from child on stop so that it
468 is more easy to spot problems with child worker processes.
470 retrieval: empty backend name attribute omits element set
471 from being used in retrieval.
473 --- 4.2.40 2012/10/04
475 Implement Solr sort strategy "solr", similar to sru11 sorting.
476 This will implement the correct parameters on Solr requst to do
479 --- 4.2.39 2012/09/28
481 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
484 MARC: Extra/missing indicator handled for MARCXML.
485 The indicator length is given in header and is the same for the
486 whole record. If attributes ind1, ind2 are missing, then content
487 character defaults to blank. Extra indicator attributes (beyond)
488 indicator length are treated as an error.
490 Reformat: delete trailing whitespace
492 --- 4.2.38 2012/09/17
494 MARC: fix non-ASCII characters for leader. This is to ensure we can
495 generate XML in UTF-8.
497 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
498 in one node with structure word.
500 --- 4.2.37 2012/09/04
502 yaz-json-parse: JSON output may be pretty printed by using option
505 Increase default value of max message for Z39.50 Init for GFS, ZOOM
506 and yaz-client. Old value was 1 MB. New value is 64 MB.
508 --- 4.2.36 2012/08/22
510 yaz-client: don't display bogus records from SRU servers. Some SRU servers
511 return more records than given by *maximumRecords*. Skipping those in
514 record_render: simplify buffer return handling and fix at least one bad
515 memory reference, that broke the test_embed_record sometimes.
517 Allow http://user:pass@host notation for yaz_url_exec.
519 zoomsh: allow shell command to be executed. Via the system(3) call.
521 yaz_poll: Allow num_fds == 0
523 yaz-client: fix bad encoding of "itemorder item". The itemorder
524 item <no> - command forgot to use length of encoded Item Request
525 package. Error present since YAZ 3.
527 yaz-ztest: fix bad usage of session handle. Bug was introduced when
528 result sets were saved (271a9c83).
530 SRU recordPacking: guess record packing in response rather than looking
531 at the recordPacking element which, OF COURSE, changed semantics in SRU
534 Decode SRU 2.0 responses. The official namespace for responses, according
535 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
536 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
537 nature.com's server, however, usee namespace
538 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
539 we are now using a glob-expr to match up the namespace. ZOOM C and
540 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
541 I can not find a single real example showing the "real" namespace in
542 the documentation from OASIS. The namespace for requests is different
543 from responses, but this is not added to YAZ yet, when we don't encode
546 --- 4.2.35 2012/06/26
548 zoom/record_render: add support for Base64 decoding fo MARC records
549 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
550 which will decode base64 + ISO2709 marc-8 encoded material from text node
553 --- 4.2.34 2012/06/07
555 Add missing definitions ZOOM_resultset_get_facet_field_by_index
556 and ZOOM_resultset_facets_names.
558 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
561 Change APDU dump printing to avoid long leading blanks. For levels 16
562 or larger the level is shown and the indentation is truncated but
563 recursed with modula 8. This makes it still reasonable easy to read
564 - even for nested BER dumps.
566 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
567 return 0 (incomplete package) in case where the BER package was
568 considered too nested (return value of -2).
570 dumpber: lines of level 15 are not indented further. Two spaces per
571 indentation; indentation 15 or more is indented to a fixed indentation
572 and augmented with a level=<no> indication.
574 zoomsh: increase max size of command+args
576 GFS: No limit in RPN buf size in CQL to RPN conversion.
578 --- 4.2.33 2012/05/09
580 New function for daemon utility, yaz_daemon_stop .
582 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
584 --- 4.2.32 2012/04/25
586 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
587 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
589 --- 4.2.31 2012/04/23
591 YAZ daemon utility relays SIGUSR1 to child process.
593 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
594 would result in en empty database list - which in turn would result in
595 encoding failure for search.
597 Fix reading beyond string in yaz_sort_spec.
599 --- 4.2.30 2012/04/11
601 Add two new SRU diagnostics:
602 236: Access to specified database denied
603 1015: Init/AC: Maximum number of simultaneous sessions for Userid
605 Document the very useful ZOOM-C option "apdulog".
607 CQL to RPN: term may be passed through verbatim. This is enabled with
608 truncation.cql . The assumption being that the term is already CQL.
610 --- 4.2.29 2012/03/20
612 record_conv: leader spec may be given for marc element.
613 The leader spec is given as attribute leaderspec for element marc.
614 For example to convert a MARC21 record from MARC-8 to UTF-8:
615 <marc inputformat="marc" outputformat="marc"
616 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
618 record_conv: allow user-XSLT params. For example:
619 <xslt stylesheet="MARC21slim2DC.xsl">
620 <param name="myparameter" value="myvalue"/>
621 <param name="otherparameter" value="othervalue"/>
624 record_conv: fix error handling for missing marc charsets.
626 CQL: fix extra terms in wrong order.
628 --- 4.2.28 2012/03/06
630 record_conv: modify new API for conversion types. The conversion types
631 may be passed in new functions yaz_record_conv_configure_t and
632 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
634 Avoid mixed statement/variable declare; fixes compilation with Visual
637 --- 4.2.27 2012/02/28
639 Add non-standard SRU diagnostic: 235: "Database does not exist".
640 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
641 Update SRU to Bib-1 diagnostic maps accordingly.
643 CCL: add two new diagnostics for unsupported masking. The new
644 diagnostics are: "Embedded truncation not supported" and
645 "Single charcacter mask not supported".
647 --- 4.2.26 2012/02/23
649 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
651 --- 4.2.25 2012/01/11
653 Build YAZ for Ubuntu Oneiric.
655 CCL: allow parantheses for proximity operands. For example CCL query
656 (a) % (b) is now allowed.
658 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
659 marked dead, rather then being destroyed. If not, the session memory is
660 being free'd before the search/scan handler is finished. Also destroy
661 'request' memory in request_release rather than in various places,
662 which resulted in leaks from time to time.
664 --- 4.2.24 2011/12/21
666 cql_sortby_to_sortkeys: honor sort prefix.
668 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
669 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
670 The rpn2cql family of functions now always returns quoted CQL terms.
672 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
674 --- 4.2.23 2011/12/15
676 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
677 sequence is treated as one. For example, &&a=b&&&c& is identical to
680 --- 4.2.22 2011/12/05
682 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
683 APDUs for a connection to a WRBUF.
685 --- 4.2.21 2011/11/23
687 Fix cql_sortby_to_sortkeys. Completely broken before.
689 Make CCL's @truncation work again.
691 --- 4.2.20 2011/11/09
693 New ZOOM connection setting: tproxy. It's like proxy, but does not
694 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
695 to set resolved address + port for a connection outside ZOOM itself.
697 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
699 --- 4.2.19 2011/11/07
701 Fix uninitialized variable in Solr spell support (could cause SEGV
702 for SRU response decoding).
704 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
705 back-end's addinfo through into the ZOOM response addinfo.
707 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
708 they are separated by a colon and a space rather than simply
711 --- 4.2.18 2011/10/28
713 Add support for Solr spell-checking/suggestions through ZOOM.
714 If a Solr target has been configured correctly for spelling-checking
715 and suggestions, these will now be returned on the ResultSet option
716 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
718 --- 4.2.17 2011/09/28
720 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
721 with a flag whether to substitute escape sequences or not.
723 --- 4.2.16 2011/09/22
725 Fix nmem_strsplit_escape to substitute escape char properly.
727 New option for zoomsh -e , which makes it abort on first error and
728 return process exit code to indicate success/failure.
730 YAZ options utility supports special option -- which makes all it treat
731 all following arguments as non-options.
733 --- 4.2.15 2011/09/16
735 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
736 searched if absolute filename is given.
738 Fix conv_xslt() error-reporting when stylesheet is not found.
739 (The value of fullpath is meaningless in this situation.)
741 --- 4.2.14 2011/09/07
743 Fix problem in CQL sort node creation: un-initialized memory.
745 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
746 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
747 CQL sortby depending on whether Type-1 or CQL is actually sent to the
750 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
751 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
753 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
754 will make it possible to use both single-character mask (#) and wildcard (?)
755 in CCL . Throw diagnostic for left truncation because that is not supported
758 --- 4.2.13 2011/09/01
760 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
761 cases using escapes (\-sequences) and masking.
763 PQF parse fix: A trailing backslash followed by end-of-string (\0)
764 would result in a read one byte beyond string.
766 rpn2ccl may use Z39.50 masking for terms (t=z).
768 ICU check fix. Don't include library -lCrun on Solaris, unless present.
770 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
771 not --cppflags (which seeems like an error in icu-config).
773 --- 4.2.12 2011/08/27 RPM package only
775 cql2ccl: fix conversion of terms: operator characters were not
778 --- 4.2.11 2011/08/25 RPM package only
780 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
781 CCL parser will map both # and ? to their regular expression
782 quivalents (. and .*).
784 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
785 of reserved CQL characters.
787 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
788 is, so that they are passed through.
790 --- 4.2.10 2011/08/24
792 ZOOM SRU mode: more aggressive re-connect.
794 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
795 made available as a utility function, declared in <yaz/logrpn.h>
797 rpn2cql_structure() supports proximity nodes (except that the Type-1
798 proximity node's "exclusion" binary is ignored, as there is no way to
799 express that in CQL). Fixes bug #4564.
803 Fix SEGV that could occur if set command of zoomsh was given without
804 value (2nd argument).
806 Fix SEGV that could occur if unsupported transport was given for
807 COMSTACK - say https (when SSL was unavailable).
809 Build yaz-url on Windows too.
813 New utility to get web content. Header is url.h. A command line tool
814 yaz-url is part of the distribution and packages.
816 Fixes for SSL COMSTACK (when gnutls is in use).
818 New functions yaz_base64{encode,decode}. Header is base64.h.
822 ZOOM C includes HTTP response buffer as additional info if it fails
823 to decode the SRU response.
825 Make wrbuf_json_puts available.
829 zoom: throw diagnostic for invalid value for option "sru". Before a
830 bad SRU request was sent.
832 Adding new utility wrbuf_vp_puts.
834 Add cclxmlconfig.obj to win/makefile. It was missing completely.
838 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
839 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
840 redirect was used at the same time.
842 MARC line mode decoding: be less picky about length given - first
843 5 digits of header that is.
845 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
847 Changes to decoding of SRU records: a record with recordPacking=xml is
848 modified with a new root element <yaz_record> if the recordData contains
849 multiple children elements. This is to make the record XML parseable
852 RPN to Solr conversion: encode special characters.
854 Generic Frontend Server: fix uinitialized member, stepSize.
858 Fix a bug in SRU decoding of records.. The database records stored
859 had un-initialized memory, but it would only be seen with yaz_record_render
860 and type_spec="ext" .
862 Fix a bug in ccl_qual_dup introduced in 4.2.3.
866 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
870 Add new utilities to convert from CQL to CCL . These utilities have
871 prefix cql_to_ccl defined in cql.h.
873 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
874 lead to memory heap corruptions when ICU utilities were in use.
878 Make compilation work without Libxml2.
880 yaz-client: remove redundant blanks in display of searchResult-1 term
885 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
886 resulting CQL node (tree) in a new node CQL_NODE_SORT.
888 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
889 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
890 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
891 Note that the CQL sortby spec is only converted when the GFS is already
892 converting from CQL to RPN (cql2rpn element).
894 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
895 specify whether to collapse delimitors or not. The existing nmem_strsplit
896 do collapse (collapse parameter = 1).
898 Windows installer: For NSIS, set InstallDir depending on x86/x64.
900 Rename internal func yaz_use_attribute_create. While non-static, this
901 function is not declared in a public header.
905 Add -lCrun when linking with ICU on Solaris.
907 More quicks character set conversions for OPAC records.
911 fix problem with record_render: records were converted (character set
912 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
916 SRU: add methods for handling DADS SRU-proxy facets.
918 Separate OPAC record character set for ZOOM_record. yaz_record_render
919 allows a character set given as charset=from/opacfrom,to where 'from' is
920 the character set of a bibliographic record, 'opacfrom' is character set
921 of OPAC record and 'to' is the target character set.
925 yaz-client: show may XML format records. Command show followed by 'format'
926 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
929 src/stemmer.c: Avoid using unnamed union. It is not supported by some
932 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
935 Update yaz.spec to operate on both SLES11 / Centos 5.5.
937 RPM: Release includes 'indexdata' name. Use indexdata in release name so
938 this package can be distinguished from other vendors.
940 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
941 as determined by configure
943 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
945 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
946 returns no error and no record, the present request is considered
947 partial (only a subset of the records could be returned by backend), and
948 so it is appropriate to set Present Status to partial-4.
952 Move yaz-config man pages to section 1.
954 More documentation about Solr.
956 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
957 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
958 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
959 peers on some Linux systems. However, in general that does not work
960 so YAZ can not rely on that to work. Debian changed behavior in this
961 respect from Debian lenny to Debian squeeze (still testing as of Oct
963 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
965 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
969 Fix yaz-config output: echo_source not set correctly by configure.
973 Solr Web Service support for yaz-client and ZOOM.
975 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
977 --- 4.0.12 2010/08/17
979 Z39.50 facet support. Facet specifications are passed for search in
980 other-information with ASN.1 as defined in facet.asn and OID
981 .10.1000.81.5 . Facets are expressed as an Attribute list as known
982 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
983 3 is limit (number of entries to get in response). yaz-ztest returns
984 dummy facets if a client asks for them.
986 --- 4.0.11 2010/07/09
988 CCL fixes: bug 2895 and bug 3539.
990 GR1-display: add comma in display - was removed by mistake in
993 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
995 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
997 --- 4.0.10 2010/06/18
999 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1000 result set from a connection. The result set will be on its own
1001 thereafter; no operations on it will perform retrievals from a target.
1002 Only cached copies are returned.
1004 ZOOM C:fix case for HTTP servers responding with Connection:close.
1005 Ensure that if there is a current task it is resumed (like fetching
1006 more records in a result set) . Bug #3484.
1008 PQF parser: use odr_atoi for Odr_int (not atoi)
1010 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1011 values that contain any non-digits are treated as string attributes
1012 (previously decoding only checked for leading character ([0-9]). PQF
1013 encoding: attribute string values are not surrounded by double-quotes.
1015 --- 4.0.9 2010/05/21
1017 New utility for managing threads - thread_create.h.
1019 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1020 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1021 but YAZ' implementation do.
1023 Fixes for yaz_cond-functions on Windows 7.
1025 DLL export more symbols.
1027 zoomsh: show record do NOT render opac.
1029 Remove *.la files from Debian and RPM packages.
1031 --- 4.0.8 2010/05/11
1033 Debian package libyaz-dev depends on libgnutls-dev again (was
1034 removed in YAZ 4.0.6, but due to Libtool it is still needed
1035 even though yaz-config do not list libgnutls libs).
1037 ZOOM: Use only one WRBUF for returning string results for
1038 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1040 ZOOM: ZOOM_connection do not use a shared pointer to
1041 ZOOM_resultset after ZOOM_resultset is destructed by
1042 user. Reverts to YAZ 4.0.4 behavior.
1044 --- 4.0.7 2010/05/04
1046 record-conv: fix problem with at least one XSL conversion -
1047 due to probably incorrect usage of XML XSL documents.
1049 --- 4.0.6 2010/04/29
1051 Fix yaz-config for static mode and the use of SSL (gnutls).
1053 --- 4.0.5 2010/04/29
1055 Forward decl timeval struct in mutex.h and gettimeofday.h.
1057 yaz-config: fix 'static' mode linking.
1059 --- 4.0.4 2010/04/28
1061 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1062 are wrappers for pthreads or Windows. For Windows these are put in
1063 a separate DLL: yaz_cond4.
1065 libyaz.la (whole source) is compiled with thread. If thread support
1066 is enabled enabled, all source of YAZ is compiled with treading support.
1067 This allows core utilities such as yaz_log to use thread facilities.
1068 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1069 thread utilities. This commit moves mutex utilities (mutex.c) from
1070 libyaz_server.la to libyaz.la.
1072 yaz-json-parse displays leading text until error.
1074 --- 4.0.3 2010/04/09
1076 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1077 patch from Giannis Kosmas.
1079 SRU: no longer URL encode SRU database. The URL for an SRU server is
1080 a URL and such is alreeady encoded - at least when given with leading
1081 http:// or https://. This reverts behavior to YAZ 3.0.50.
1083 Support for new MARC XML notation TurboMARC which like MARCXML is a
1084 complete representation of MARC/ISO2709.. This one, however, is more
1085 compact and allows for faster processing with XSLT. TurboMARC can be
1086 used in the marcdisp.h API, from the yaz-marcdump utility and from
1089 yaz-ztest can be configured - via the database - to perform certain
1090 delays when it performs operations search, present and single record
1091 fetch. This allows testers to make yaz-ztest act as a real or even slow
1092 Z39.50 server. Refer to the yaz-ztest man pages for details.
1094 --- 4.0.2 2010/03/09
1096 wrbuf_destroy allows NULL WRBUF passed to it.
1098 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1100 Add ZOOM_connection_close.
1102 No fixed size buffers for ZOOM shell - bug #3257.
1104 tstodr: make it work on s390 platform.
1106 New icu iterator-functions. The new icu_iter-functions makes it possible
1107 to use ICU chains from many threads.
1109 yaz-client: better syntax check for show command.
1111 --- 4.0.1 2010/01/26
1113 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1116 New simple local-file XML include facility which allows file glob-patterns.
1117 Refer to yaz/xml_include.h.
1119 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1122 ZOOM_record_get supports new parameter "format" which makes it format XML
1125 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1126 JSONText in ECMA-262) is JSONValue, not JSONObject.
1128 --- 4.0.0 2010/01/20
1130 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1131 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1133 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1134 POSIX/Unix builds .so with major version 4.
1136 Remove old LOG_-defines from log.h. They have been obsolete and
1137 undefined by default for the last 5 years.
1139 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1141 GFS: Remove socket (int *fd) from search_rr handler. The socket
1142 descriptor ptr is a facility that allowed a search handler to supply
1143 a socket which would serve as a callback - when search was complete.
1144 This facility has now been in use for years.
1146 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1147 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1148 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1149 returns 'const char *' rather than 'char *. The returned string is
1150 read-only and should not be modified by applications. COMSTACK cs_close is
1151 now a void function - it no longer returns int. No applications check for
1152 the value and the implementations has always returned 0.
1154 ZOOM: use size_t for scan hit counts and str size. Functions
1155 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1156 occ (hit count) and len (string length) are now of type size_t pointer
1157 rather than int pointer. This is to be able to represent large hit counts
1158 and to also just to use the proper type for string length (strlen result).
1160 New JSON parser. Refer to include/yaz/json.h .
1162 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1163 Used to be int in some cases. Many wrbuf_-functions used to return an int
1164 indicating some length.. These return values were never used. And so they
1167 ODR: odr_malloc, odr_total now takes size_t for size.
1169 clone_z_type: fix leak; occurred for encoding failures.
1171 --- 3.0.52 2009/12/03
1173 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1174 bug was introduced in 3.0.51.
1176 --- 3.0.51 2009/12/02
1178 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1180 tcpip comstack: fix leak for getaddrinfo.
1182 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1183 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1184 Decoding of SRU "path" database is performed by private function
1185 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1186 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1188 yaz-client: honor base command for SRU. Change when database setting
1189 is applied for SRU and ensure it is kept when a connection is reset.
1190 Change also the way errors are displayed or SRU (decoding of packages).
1192 --- 3.0.50 2009/11/02
1194 Add support for extra request / response data for SRU codecs and GFS.
1195 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1196 for extra data response buffer and length. For the GFS, both request
1197 and response data (XML) is carried in extra_args and extra_response_data
1198 for the search handler. Patch by Ko van der Sloot.
1200 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1201 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1202 10010). This fixes bug #2113.
1204 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1205 cmdfile included a 'quit' command that would result in a memory violation.
1207 --- 3.0.49 2009/10/01
1209 Make a number of functions defined in xmlquery.c static. These have
1210 never been declared in a public header file (yaz/xmlquery.h) and was
1211 made public by mistake.
1213 Improve speed of character conversions (iconv utilities). This makes
1214 conversions from MARC-8 faster.
1216 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1217 unless type desired is "raw". This will prevent type "xml" from
1218 returning ISO2709 .. Which obviously can not be XML parsed.
1220 Fix memory leak in ZOOM that would occur if option apdulog was used
1221 on a re-used connection.
1223 Frontend server logs HTTP requests.
1225 Frontend server now sends Z39.50 close when it times out (sesssion has
1226 been idle for too long). Versions 2.0.30 and earlier also sent close.
1227 But due to a mistake this was disabled in all versions after that, i.e.
1228 the server would just close the socket immediately.
1230 yaz-client emits a better message when receiving an unrecognised
1231 userInformationField.
1233 Skip zero-length subfields when decoding ISO2709. This rare case happens
1234 if a record has two FS characters in a sequence. Without this patch
1235 there would be a reference beyond char array in using_code_len fragments
1238 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1240 --- 3.0.48 2009/08/28
1242 The show command offered by the zoomsh command now takes a 3d optional
1243 parameter type which is what is passed to ZOOM_record. If the type
1244 argument is omitted, "render" is used.
1246 RPN to CQL conv may use USE string attributes (bug #2978).
1248 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1250 --- 3.0.47 2009/07/08
1252 Function yaz_xml2query allows a diagnostic element in the PQF XML
1253 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1254 code and additional info respectively.
1256 The BER BOOLEAN is now the integral type Odr_bool which still happens
1257 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1258 typedef'd to Odr_int. This is still an integral 'int', but it may be
1259 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1260 ASN-1 compiler as well as programs has been updated to use the new types.
1262 --- 3.0.46 2009/06/08
1264 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1265 only the bibliographic record was rendered. For type=opac, an OPAC
1266 record is only returned if it is present.
1268 iconv: small fix for encoding of advancegreek.
1270 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1272 yaz-client: option auto_reconnect=on really reconnects.
1274 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1276 server: avoid null ptr ref for for yaz_poll errors.
1278 build: fix RPM build for RHEL 5.3.
1280 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1282 --- 3.0.45 2009/03/31
1284 Fixed bug #2709: TCP connect returns Invalid argument.
1286 Fixed compilation for mingw.
1288 Honor charset for raw records (ZOOM_record_get).
1290 Fixed use of errno for threaded mode that was seen on Solaris 10.
1292 Fixed argument passing with blanks in value for Windows Service.
1294 Disable YAZ' own log rotate by default (no 1 GB limit).
1295 The variable l_max_size which specifies the log file limit is set to 0
1296 (DISABLED): This is due to the fact that YAZ is most often deployed using
1297 logrotate. Also YAZ can not perform log rotate because of unsufficient
1298 permissions (setuid).
1300 --- 3.0.44 2009/02/17
1302 List supported encodings in man page for yaz-iconv.
1304 Fixed missing SSL libs for --libs output
1306 Re-established OID record syntax application-xml. Nobody should use it
1307 but we don't want to change soname because of this symbol being absent.
1309 --- 3.0.42 2009/02/02
1311 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1313 Added member named_result_sets for init handler struct for the GFS. This
1314 allows a server to disable named result sets.
1316 Removed OID record syntax application-xml.
1318 Added support for rule-based transliterator for ICU wrapper of YAZ.
1320 Fixed bug #1902: yaz-icu XML output.
1322 Make YAZ checks Emacs friendly.
1324 BITSTRING value shows value. Bug #2346.
1326 ISO2709 decoding: skip control characters from indicator data.
1328 Omit sort key by default in yaz-icu's output.
1330 Allow combined single char options (again) for YAZ' options function.
1332 Utility yaz-marcdump got option to display YAZ version (-V).
1334 Allow YAZ to use ICU 3.4.
1336 Added new ICU test case which illustrates removal of diacritics.
1338 --- 3.0.41 2008/12/29
1340 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1342 --- 3.0.40 2008/12/29
1344 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1347 Fixed bug #2352: yaz-marcdump crashes for certain record.
1349 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1351 Added support for Danmarc2 to UTF-8 conversion.
1353 Added support for ISO5426 to UTF-8 conversion.
1355 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1356 implementation version.
1358 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1360 --- 3.0.38 2008/11/10
1362 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1363 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1365 ZOOM C now interprets databaseName option for ZOOM connection as path
1368 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1370 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1372 Dummy Libxml2 types no longer defined in headers of YAZ'.
1374 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1377 --- 3.0.36 2008/09/26
1379 Various ODR chapter fixes.
1381 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1383 Added missing source for Windows compilation, mutex.c.
1385 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1387 For SRU connections in ZOOM all records up to "count" are now fetched.
1389 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1390 in Windows due to bad error handling for Libxml2.
1392 Added facility for sending arbitrary records (ASN.1 any) using
1393 ZOOM C's Extended service update. Patch by Sam Reynolds.
1395 New options for ZOOM C's connection, logapdu which makes ZOOM log
1398 --- 3.0.34 2008/06/18
1400 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1402 --- 3.0.32 2008/06/12
1404 Fixed memory violation that could occur when decoding UTF-8. This bug
1405 was only present in 3.0.30 of YAZ.
1407 --- 3.0.30 2008/06/06
1409 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1410 GNU TLS is used by default (if found).
1412 yaz-ztest returns OPAC records if a client asks for OPAC.
1414 Improved speed of MARC-8 encoding.
1416 Added support for lossy and loss-less MARC-8 encoding.
1418 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1420 Added new Windows Service wrapper (sc).
1422 yaz-client's itemorder command may now send a file.
1424 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1426 Added new function yaz_log_xml_errors.
1428 Allow (but warn) unknown XML attributes in MARCXML parsing.
1430 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1432 The UTF-8 to MARC-8 conversion now uses a different set of characters
1433 for Greek symbols. Bug #2120.
1435 --- 3.0.26 2008/02/21
1437 Added yaz_daemon (daemon.h).
1439 Fixed bug #2068: pkg-config trouble
1441 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1443 --- 3.0.24 2008/01/28
1445 Document --with-xml2 option.
1447 Added OPAC XML XSD (etc/opacxml.xsd).
1449 Allow glob mask for name attribute in retrieval element for the
1450 generic frontend server's retrieval facility.
1452 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1453 except POLLIN/POLLOUT.
1455 Fixed error handling in cs_listen. Bug #2037.
1457 --- 3.0.22 2008/01/20
1459 Fixed version in yaz/yaz-version.h.
1461 Fixed bug #2027: Crash when closing connection.
1463 Changed configure so that ICU support is only enabled if only ICU
1464 and Libxml2 is available (because the ICU chain is XML based).
1466 --- 3.0.20 2008/01/15
1468 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1469 is built. Only this DLL depends on the ICU runtime.
1471 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1472 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1474 Changed license of CCL module to 'Revised BSD'. After consultation with
1475 remaining members of the original EUROPAGATE consortium, we are re-issuing
1476 the CCL module without a separate license. The software was developed by
1477 Index Data as part of a research project. The special license was included
1478 to help feed usage information back to the project consortium to support
1479 project evaluation. At this time, the project consortium has long-since
1480 disbanded, and the majority of the original principals have retired. At the
1481 same time, we have significantly modified the software during the following
1482 years, to the point where very practically no original code remains. To
1483 simplify re-use of the software, we have contacted those members of the
1484 consortium who could be reached, and agreed to re-issue the module as a
1485 proper part of the YAZ package.
1487 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1489 CQL closer to being version 1.2 compliant. CQL also allows free-form
1490 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1493 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1494 bug could make Extended services handling crash in the ZOOM layer. This
1495 bug was only present in YAZ 3.0.18.
1497 --- 3.0.18 2007/12/19
1499 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1502 yaz-marcdump reads and writes collection wrapped records.
1504 Handle OPAC for record conversion module.
1506 Fixes for ICU wrapper.
1508 Allow ICU libs to be controlled with --with-icu .
1510 --- 3.0.16 2007/11/12
1512 Added yaz_poll which is a wrapper for select/poll. When poll is available
1513 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1514 sockets to be in use.
1516 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1517 functionality through an XML based configuration (ICU chain). This system
1518 is useful for search facilities such as Pazpar2 and Zebra that needs to
1519 perform tokenization of indexed material. The ICU code in a separate
1520 library libyaz3_icu.a.
1522 Added HTTP tunnel facility for COMSTACK, bug #1752.
1523 This is a facility that allows a Web proxy, such as squid, to tunnel
1524 Z39.50 traffic. This facility is "transparent" to must applications
1525 using YAZ. It's enabled by using pseudo transport connect: followed by
1526 the proxy address, followed by command, then follwed by he regular
1527 "virtual" addresss. For example,
1528 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1530 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1532 --- 3.0.14 2007/09/21
1534 Fixed bad memory reference in ZOOM_record - cuased by member not being
1535 initialized. This was a problem only in YAZ 3.0.12.
1537 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1538 fields were not removed.
1540 Changed the way C code is generated from codetables.xml. Made a MARC-8
1541 conversion trie for each characterSet section rather than codeTable.
1542 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1543 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1545 --- 3.0.12 2007/09/12
1547 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1548 from ZOOM_record_error).
1550 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1552 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1554 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1556 Better SRW-to-Bib-1 diagnostic mapping.
1558 ZOOM C and yaz-client announces SRU version 1.2 by default.
1560 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1563 Fixed in yaz_sru_decode to allow other version than 1.1.
1565 --- 3.0.10 2007/08/22
1567 Added support for SRU scan for ZOOM.
1569 Added support for the use of the older versions or Extended Service
1570 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1571 set to the version , 1=first, 2=second, 3=third. The third version is
1572 what ZOOM C has used so far. And that, obviously, is the default.
1574 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1575 therefore in Zebra and in SimpleServer-based applications). The new
1576 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1577 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1578 which is passed into the back-end search callback function.
1580 Added support for HTTP Basic authentication in clients: the SRU/W
1581 codec encodes the username/password elements of the PDU structure
1582 appropriately, and these may be set using the "user" and "password"
1583 options in ZOOM-C applications (the same options that are used for
1584 Z39.50 authentication).
1586 --- 3.0.8 2007/06/25
1588 Fixed bug #1208: SSL appears to be broken in ZOOM.
1590 Fixed bug #1206: Libxml2 include path weirdness.
1592 Added oid_name_to_dotstring.
1594 Allow elementSetName to be specified for ZOOM C record update.
1596 Allow waitAction to be specified for ZOOM C based for Extended Services.
1598 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1599 syntax OID. Bug introduced in YAZ 3 series.
1601 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1603 --- 3.0.6 2007/06/06
1605 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1606 directory. yaz-client now reads commands from file given by option -f
1607 if specified; then tries to read .yazclientrc in current directory.
1608 Failing that, it reads .yazclientrc from user's home directory.
1610 Added support for correlationInfo Note and ID for Record Update via
1613 Added yaz-client command querycharset which specifies character set for
1614 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1615 (termListAndStartPoint).
1617 Charset ISO5428:1984 is an alias for ISO5428-1984.
1619 Implemented a way to perform scan in a result set using Z39.50. This
1620 is achieved by attaching the result set name in the characterInfo
1621 (type InternationalString) of OtherInformation in the Scan Request PDU.
1622 The result set is identified in the otherinformation by the new OID:
1623 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1624 This allows for scan in result set and faceted search . Zebra did some
1625 of this in the APT term using attribute type 8 and value being result
1626 set. Using the OtherInformation approach for this is cleaner and easier
1627 to work with in proxies and the like. This facility can be used in
1628 yaz-client using new command setscan which takes a result set as first
1629 argument, start position (APT) as second.
1631 Changed decoding of SRU XML packed records to deal with servers that
1632 have recordData with XML data with multiple root nodes. Also make
1633 comparison for recordPacking case insensitive. Again, one server
1634 returns "XML" where others return "xml".
1636 For SRU responses allow Content-Type application/xml as well as text/xml.
1638 --- 3.0.4 2007/05/21
1640 Fixed bug in character set conversion of BER strings. Bug introduced
1643 --- 3.0.2 2007/05/08
1645 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1647 For OID class, use oid_class consistently.
1649 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1652 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1653 character set for bibliographic information interchange". By Giannis Kosmas.
1655 Added documentation on new OID API.
1657 --- 3.0.0 2007/05/02
1659 Changes to generic frontend server interface: added new member
1660 'query_charset' for bend_initrequest structure. A backend init handler
1661 should set this member to its native character set for query terms.
1662 When defined, the frontend server logic will announce this character set
1663 to a client if the negotiationModel bit is set by the client. All server
1664 implementors are encouraged to specify this. If a backend server does not
1665 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1667 Added CCL utility to remove terms (stop words) from resulting RPN
1668 tree. This is handled by functions with prefix ccl_stop_words_ .
1670 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1671 terms in RPN queries.
1673 Clean-up the CCL API. Moved some internal structures from ccl.h to
1674 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1675 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1676 This is replaced by ccl_parser_find_str which takes a string instead.
1678 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1679 libyaz.la is the core of YAZ except the generic frontend server and
1680 does not depend on POSIX threads anymore. libyaz_server.la is the
1681 generic frontend server facilities and uses POSIX thread functionality
1682 if available. The libyaz.la no longer depends on POSIX threads because
1683 the number of global structures is limited. NMEM no longer re-uses blocks
1684 between threads ; it simply free's memory immediately but allocates in
1685 "large" chunks as usual. We don't expect any performance penalties
1686 because of this. The yaz_log system is still using a global log_level so
1687 caution must be taken when modifying it with yaz_log_init_.. +
1688 yaz_log_mask_str. This, however, should not cause any trouble because
1689 these functions are called during initialization of application code
1690 anyway. `yaz-config --libs server` returns libs for server applications;
1691 `yaz-config --libs` returns libs for non-server applications.
1693 New OID database - with public definitions in oid_db.h. Removed old OID
1694 database including the head oid.h and definitions such as enum oid_value
1695 and struct oident. The new OID database uses the same string names as
1696 before but the 'protocol' is gone. There are now only two representations
1697 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1698 converts from string to OID; functions with prefix yaz_oid_to_string
1699 converts the other way.
1701 Change to emit_term() in CQL-to-PQF query translation: when a term has
1702 the /regexp relation modifier, do not process it for leading and
1703 trailing "^" and "*", which have quite different meanings in regular
1706 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1707 write handlers no longer carries a 'last' parameter. This will make
1708 yaz_iconv flush "less" characters. A flush is performed by call to
1709 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1711 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1712 removed, because function yaz_query_to_wrbuf does the same.
1714 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1715 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1717 Deprecated MARC utility functions removed.
1719 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1722 Branch split: YAZ_2_1_55_branch
1724 --- 2.1.54 2007/03/16
1726 Fix to ZOOM-C so that transparent reconnection is properly handled on
1727 connections that are in asynchronous mode.
1729 Fixed compilation on OpenBSD 4.0.
1731 Large strings in GRS-1 records are now properly displayed in yaz-client.
1733 Added character conversion support for "advancegreek"; based on patch from
1736 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1737 sequence is met. Before the error was not set so it would be unknown.
1739 Adjust yaz-marcdump MARC reader so that it skips until record separator
1742 --- 2.1.52 2007/03/07
1744 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1745 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1746 fd_set structure used as a bitmask for the FDs to be selected on.
1748 Using ACX_PTHREAD macro to check for POSIX threads.
1750 Fixed have-vsnprintf check.
1752 --- 2.1.50 2007/02/23
1754 Fixes for configure on BSD. Bug #900.
1756 Added snprintf/vsnprintf wrappers for systems that don't have
1757 limits (heavens forbid).
1759 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1760 created before all previous tasks were completed and removed from the
1761 task queue, the new task could be removed by a mistake.
1763 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1765 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1767 Fixed bug #832: Problem with MARC/charset in yaz-client.
1769 Fixed bug #668: save command line history for yaz-client.
1771 Fixed bug #830: pkg-config support.
1773 --- 2.1.48 2007/01/23
1775 Extended ZOOM result set options with two options that may be read by
1776 a client: resultSetStatus and presentStatus with values as specified for
1778 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1780 Fixed bug #827: Using SSL fails on Debian etch.
1782 Fixed bug #826: Weird looking chars for set of MARC records.
1784 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1785 that is treated as an ItemOrder with itemRequest being an XML document
1786 external. The value of "doc" is the content.
1788 Extended the GFS search facility. New member of bend_search_rr
1789 'estimated_hit_count' signals that hits is known to be an estmate
1790 (higher or lower than real hit count). New member 'partial_resultset'
1791 signals that the search was partial (hit count is lower or equal than
1792 real hit count). For Z39.50, the information is stored in resultSetStatus
1793 member of SearchResponse APDU. For SRU, the information is signalled
1794 via SRU diagnostic 59: "Result set created with valid partial results
1797 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1799 --- 2.1.46 2007/01/13
1801 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1803 Added ZOOM_connection_peek_event.
1805 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1806 the following new functions:
1807 ZOOM_event_nonblock, ZOOM_connection_process,
1808 ZOOM_connection_get_{socket,mask,timeout},
1809 ZOOM_connection_fire_event_{timeout,socket}.
1810 The existing blocking event handler, ZOOM_event, is a wrapper for the
1811 + blocking ZOOM_event_sys_{poll,select}.
1813 Implemented function ccl_xml_config which parses XML version of CCL
1814 configuration (bug #798).
1816 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1818 Added timings utility (yaz/timing.h)
1820 --- 2.1.44 2007/01/03
1822 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1825 Fixed bug #779: Rotation of apdu.log fails.
1827 Fixed for character set conversions:
1828 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1829 Honor G1 set in MARC-8 decoding.
1831 --- 2.1.42 2006/12/17
1833 Fixed bug #775: char conversion does not handle Alternative UTF-8
1836 Implemented function yaz_marc_read_line which parses MARC line format
1837 records. There is a wealth of formats out there. So far, this function
1838 reads line records produced by yaz_marc_write_line.
1840 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1841 more generic and easier to remember(!) options: -i format and -o format
1842 which specifies input format and output format respectively - where
1843 format is one of "marc", "marcxml", "line", "marcxchange".
1845 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1846 does not print anything except warnings for records.
1848 For yaz-marcdump, added support for MARC split into files (-s) with a given
1851 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1852 spec, at http://www.loc.gov/standards/sru/record-update/
1853 This has changed the binary layout of the following structs:
1854 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1855 bend_update_rr . Patch by Ko van der Sloot.
1857 Added GFS utility function bend_assoc_is_alive which returns 1 if
1858 association is still alive (client is connected); 0 otherwise (client
1859 closed connection). This allows busy servers to stop working for
1862 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1863 been a separate piece of software. This version of ziffy has been modified
1864 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1866 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1868 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1869 Client code may now interrogate options such as "init_opt_sort" to
1870 find out whether the server claims to support various options.
1872 --- 2.1.40 2006/11/27
1874 Added utilities yaz_{set,get}_esn to set/get element set name from
1877 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1878 of YAZ and has been so since YAZ 2.1.10.
1880 Implemented ZOOM_record_error which returns error information for
1881 record (surrogate diagnostic).
1883 --- 2.1.38 2006/10/31
1885 Updates for SRU Update by Ko van der Sloot:
1886 1. Changed name from "operation" to "action"
1887 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1888 versions in the code, marked as 'backward compatible'.
1889 3. Added diagnostics for SRU Update.
1891 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1893 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1895 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1897 For GFS, fixed problem with SRU diagnostic 'First record position out of
1898 range' being issued for 0 hits.
1900 zoomtst10 part of Windows Build.
1902 --- 2.1.36 2006/10/13
1904 Implemented yaz_filepath_comp which splits a path into file path
1905 components (required by Zebra 2.0.3+).
1907 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1908 BSD inspired license until now so this should not have any real impact on
1909 anybody. See http://www.opensource.org/licenses/bsd-license.php
1911 Fixed bug #687: Missing log lines.
1913 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1916 Fixed bug #689: SRU diagnostics to be added.
1918 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1919 whether a connection is idle (no more work do do).
1921 --- 2.1.34 2006/10/04
1923 Change type of optval from long to int for invocation of setsockopt with
1924 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1926 Added support for specifying the max log file size for the Generic
1927 Frontend Server. The size is given with option -r.
1929 --- 2.1.32 2006/09/21
1931 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1933 --- 2.1.30 2006/09/17
1935 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1938 Fixed bug in Generic Frontend Server that could cause a server to stop
1939 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1941 For the generic frontend server, the maximum record size is used as maximum
1942 size of incoming packages (SRU + Z39.50). The value until was previously
1943 only used in Z39.50 Init negotiation and, later, in a session controlled
1944 sizes of records returned. This is controlled using -k option. It can be
1945 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1947 --- 2.1.28 2006/09/04
1949 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1952 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1954 New option for yaz-marcdump -lpos=value which allows setting a portion
1955 of MARC header to a certain value.
1957 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1959 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1960 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1962 --- 2.1.26 2006/08/15
1964 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1967 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1969 --- 2.1.24 2006/08/08
1971 Fixed MARC ISO2709 encoding routines to deal with character set
1974 Minor changes to GFS logging. Database included in search request log
1977 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1978 cached/multiple records.
1980 Shared libraries are built by default on Unix+configure.
1982 Changed cql2pqf transformation to use a different evaluation order. The
1983 new order is: always, relation, structure, position, truncation, index
1984 and relationModifier. Old order was: always, relation, relationModifier,
1985 structure, index, position, truncation. Note that the the latter ones
1986 override former ones for identical attributes.. The new scheme means that
1987 it is possible to override any existing attribute with a relationModifier.
1988 And also that it is possible to override everything for the index rule
1989 (except the ones listed in relationModifier). No order is perfect but this
1990 one, we believe, covers more real cases.. The "always" should have been
1991 called "default", since the attributes there can be overridden with all
1994 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1995 compilation phase, but also for yaz-config --cflags output. This allows
1996 us to have public headers with Libxml2 stuff in them . It should also,
1997 eventually, make Libxml2 checks redundant in packages using YAZ, such
2000 --- 2.1.22 2006/06/15
2002 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2003 stored in uri, message and details.. Previously diagnostics were stored
2004 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2005 compatibility.. but he's probably the only one affected, so.
2007 Added support for CCL, compiled on the client side, in ZOOM-C. This
2008 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2009 input; the resulting query objects can be used for for searching with
2010 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2012 YAZ' configure searches for OpenSSL by default.
2014 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2015 SL_CTX_use_certificate_file. See
2016 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2017 for more info. Thanks to Ko van der Sloot.
2019 --- 2.1.20 2006/06/02
2021 Bug #600: SRU GET, POST support for yaz-client. Introduced
2022 command 'sru' which selects method SOAP/GET/POST.
2024 Allow missingValueAction to be specified for the sortspec string -
2025 function yaz_sort_spec. By default, the missing value action is null.
2026 Use ! to specify "abort". Use = followed by stringvalue to specify default
2029 Ensured that Present-handler (if defined) is called in GFS before any call to
2030 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2031 searchRetrieve requests.
2033 Documentation for YAZ is now based on the Docbook XML/XSLT using
2034 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2035 is no longer depending on jade/openjade or docbook-to-man scripts.
2036 PDF is no longer part of the distribution - but can optionally be
2037 made using DSSSL/jadetex or FOP.
2039 Added retrieval handling support in Generic Frontend Server to support
2040 conversion between MARC/XML as well as XSLTtransforms. See
2041 etc/yazgfs.xml for an example.
2043 Added Authentication support to Generic Frontend Server in SRU
2044 mode. Authentication using HTTP Basic is supported, as is the use
2045 of 'x-username' and 'x-password' parameters in the request itself.
2047 Added support for a new character set MARC8s identical to MARC8 except
2048 that it converts combined characters to single Unicode characters in the
2049 Latin-1 range (when possible).
2051 --- 2.1.18 2006/04/24
2053 ASN.1 compiler 0.4: generates brief Doxygen file header for
2054 generated .h/.c files.
2056 Utility yaz_iconv now supports conversion to MARC-8.
2058 New facilities for the MARC module. The reading - and writing of
2059 content are separate methods for the yaz_marc_t handle. The following
2060 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2061 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2062 format). Write functions have prefix yaz_marc_write_.. The existing
2063 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2064 available. Removed support for OAI-MARC and simplexml (not the
2065 simplexml from PHP5).
2067 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2068 to be returned for this connection.
2070 --- 2.1.16 2006/03/31
2072 Allow multiple languages and charsets to be specified with
2073 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2074 negcharset iso-8859-1,utf-8
2076 Translation of proximity nodes from CQL into PQF now works.
2078 Moved to automake 1.8, 1.9.
2080 Added function yaz_log_set_handler which allows a log handler to be
2081 installed. This handler will be called for all log messages. Output
2082 to file is also produced; but that can be disabled by passing NULL
2083 fname to yaz_log_init_file.
2085 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2087 For SRW (including GFS), accept application/soap+xml as content-type
2090 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2091 produces NO stylesheet reference even if a default stylesheet is specified
2094 --- 2.1.14 2006/03/14
2096 Updated Windows package to include yazd.dll + yazd.lib for the
2097 Development component.
2099 If the environment variable YAZ_LOG is set, then it is used as a
2100 string indicating the default level of logging to use if not
2101 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2102 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2103 used as before. So, for example, to omit warnings from YAZ logging,
2104 export YAZ_LOG=-warn
2106 cql_transform() now map structure and other attributes before indexes,
2107 so that index-specific structures and other attributes can override
2108 defaults. So now a combination of mapping specifications such as:
2110 index.dc.date = 1=date-modified 4=5
2111 does the right thing.
2113 cql_transform() now also respects the "always" mapping specification,
2114 which establishes an initial set of attributes to be used for all
2115 terms except where overridden by more specific attributes associated
2116 with the index, relation or modifier.
2118 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2119 which mode to use; one of "post", "get" or "soap" (SRW, default).
2121 Fixes for yaz_iconv routines: changed trie-based character set conversions
2122 to use only non-negative values for bit fields due to Sun's C compiler not
2123 supporting negative values.
2125 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2126 sequences where not read correctly. Fix by Rustam Usmanov.
2128 Updated win/makefile to use options, settings which makes things
2129 compile with VS C 2005.
2131 --- 2.1.12 2006/02/01
2133 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2135 In ZOOM socket code, use select instead of poll on MacOSX.
2137 ZOOM-C now support client-side compilation of CQL into RPN that is
2138 sent to the server, enabling CQL to be used against all Z39.50
2139 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2140 ZOOM_query object, and submit it using ZOOM_connection_search().
2141 The CQL-to-RPN translation uses a configuration file, the name of
2142 which must be specified in the Connection's "cqlfile" option.
2144 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2145 function, which takes as its start-term parameter a ZOOM_query object
2146 (which may have had either CQL or RPN set into it).
2149 --- 2.1.10 2005/11/29
2151 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2152 GFS to support this as well. Backend handler, bend_srw_update, does the
2153 update work. Code contributed by Ko van der Sloot.
2155 Allow retrieval of Search Result-1 information in ZOOM by the use of
2156 options that are attached to a result set. ZOOM documentation updated
2159 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2160 UTF-8 conversion. Patch by Raj Patel.
2162 Added option -m to GFS to control formatting of timestamps in log file.
2164 Added 'exit' as synonym for 'quit' in yaz-client
2166 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2167 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2168 for the new members. Patch by Ko van der Sloot.
2170 Added support for SRU POST. It is supported for content-type
2171 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2173 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2174 Instead make the library libyaz.la multi-threaded. Threading as a whole
2175 can still be disabled by configure option --disable-threads. Previosly,
2176 with older GLIBCs there were problems with MT libs under Apache. This
2177 has now been fixed a long time ago.
2179 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2182 CQL module modified to be case insensitive for relations/indexes/operations.
2184 Fixed bug in CQL transform code: incorrect value relationModifieder
2187 Added 'show all' command for yaz-client which retrieves all results
2190 Added new yaz-client, xmles, which takes a (private) OID and
2191 a document to be sent as an extended service request.
2193 Describe new yaz-client commands wait_response and set_auto_wait.
2195 Increase TCP/IP listener backlog from 3 (which I am guessing was
2196 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2197 that the socket will queue as many incoming connections as it's able
2198 to handle ongoing connections. In other words, it will never now
2199 refuse a connection that it would be able to handle merely because
2200 it's not got around to accepting() enough of the pending connections
2201 yet. This is the behaviour anyway under Linux, where the listen()
2202 argument is ignored; but not under BSD and on systems such as
2203 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2204 YAZ-based servers should now be uniform across operating systems in
2207 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2208 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2209 This allows yaz-marcdump to read large MARC batches (>2 GB).
2211 Modified all YAZ source files - except the source which is auto-generated
2212 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2215 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2216 corresponding to the existing *_setl() function. These allow option
2217 values containing arbitrary valuues.
2219 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2220 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2221 except that it returns an indicator of whether or not the sort
2222 criterion was accepted (0 for OK, -1 for invalid).
2224 --- 2.1.8 2005/06/07
2226 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2227 MARC output rather than returning "new" buffer.
2229 yaz-client warns about unknown init options.
2231 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2233 --- 2.1.6 2005/05/24
2235 Added support for SRW sort in Generic Frontend Server. Patch
2236 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2237 sortKeys - or NULL if none is provided.
2239 Fixed bug #307: It was impossible to specify indefinite/no timeout
2240 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2243 Added support for multiple languages and charsets to be specified in
2244 ZOOM. Each charset/language is separated by a blank. If negotiation is
2245 in effect in init-response, Option
2246 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2247 Code based on patch by Vasiliy Osadchuk.
2249 Fixed bug #306: infinite recursion that occurred when calling
2250 yaz_log_level_init as the first call (before other log level or
2253 Fixed bug in scan handling in front end server: if preferred-Position-In-
2254 Response was non-present, a NULL pointer referece was performed.
2256 --- 2.1.4 2005/04/26
2258 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2259 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2260 now defined for all those error codes. So instead of putting 109 in
2261 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2262 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2264 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2267 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2269 Program yaz-client now exits and produces an error message if multiple
2270 Z39.50 servers are specified on the command line (none or one allowed
2273 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2276 --- 2.1.2 2005/03/16
2278 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2280 Fixed bug #272: Preserve spacing for CCL terms.
2282 --- 2.1.0 2005/03/14
2284 Added support for virtual hosts and multiple backend servers for
2285 the YAZ frontend server. The configution is XML based and
2286 support specificition of CQL to RPN mappings and explain information.
2287 See section "Virtual Hosts" in the YAZ manual.
2289 Extended OPAC display utility. OPAC display utility renders
2290 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2291 to supplement yaz_marc_decode_wrbuf.
2293 Fixed a bug in MARC decoder that could caused it to crash for some
2294 invalid MARC records. More diagnostics and warnings where added in
2295 XML output (warnings, etc are stored in comments).
2297 --- 2.0.34 2005/02/08
2299 Fixes for UNIX domain sockets. Bug #261.
2301 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2303 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2304 Added yaz_marc_subfield_str which defines subfield lead string which is
2305 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2306 yaz_marc_endline_str which defines end of fields string used in
2307 YAZ_MARC_LINE format. Default string is newline.
2309 Experimental support for MarcXChange. This format can be produced
2310 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2311 http://www.bs.dk/standards/MarcXchange.xsd
2313 Added yaz-client commands scansize that sets maximum number of
2314 entries to be returned by scan.
2316 --- 2.0.32 2005/01/11
2318 Added support for SRW scan in yaz-client and Generic Frontend Server.
2320 * Added whereInList member to SRW Scan Term.
2322 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2324 Fixed NMEM system to return aligned blocks on the smallest boundaries
2325 that are suitably aligned for all possible types on the particular
2326 architecture YAZ is being built for.
2328 --- 2.0.30 2005/01/04
2330 Fixed numerious warnings that was issued with newer versions of GCC.
2332 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2333 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2336 Make YAZ Generic Frontend Server slightly faster.
2338 Enhance (and reduce) logging for Generic Frontend Server.
2340 Revert YAZ log system so that it flushes every write operation
2341 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2343 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2344 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2345 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2346 will effectively disable old definitions.
2348 --- 2.0.28 2004/11/09
2350 Added yaz_log_time_format which specifies log format using
2353 Added yaz_log_module_level which returns mask for a module. Value
2354 is non-zero mask a if module is enabled; zero if disabled.
2356 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2357 in include/yaz/cql.h.
2359 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2361 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2363 Fixed bug #172: RPM builds does not enable SSL.
2365 Doxyfile.in part of dist. Doxyfile generated by configure.
2367 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2368 are given and the corresponding component does not exist.
2370 Extend CCL documentation in YAZ reference. Describe r=r.
2372 --- 2.0.26 2004/10/01
2374 Fixed MARC->MARCXML conversion to properly deal with
2375 fields, subfields, indicators having non-ASCII characters.
2377 Fixed MARC->MARCXML conversion so that ASCII control characters
2378 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2381 Added YAZ GFS support for conversion from Z39.50 surrogate
2382 diagnostics to SRW surrogate diagnostics.
2384 Bug fix: YAZ GFS did not return schema in explainResponse.
2386 --- 2.0.25 2004/09/30
2388 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2389 now converts recordSchema to elementSetName as well as schema URI.
2391 Fixed bug in COMSTACK that prevented HTTP request packages from being
2394 --- 2.0.24 2004/09/29
2396 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2397 does not require white-space before and after the dash in a range, e.g.
2398 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2401 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2402 due to new GCC removing "redundant" code.
2404 Added yaz-client commands scanpos and scanstep that sets preferred
2405 position and step-size for scan.
2407 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2409 Added CCL utility ccl_qual_buf which parses one or more CCL
2410 spec lines in a buffer.
2412 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2413 of name and value - ignoring empty lines and comments.
2415 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2417 Added odr_get_element_path which returns current element path for an
2418 ODR handle. This utility is useful in error handling or user-defined
2421 Added ODR_PRINT utility odr_set_stream which is is a more generic
2422 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2423 to a write function and pointer to close function. The close function - if
2424 non-NULL - will be called during odr_destroy.
2426 Fixed bug in CCL parser where truncation char was not removed from
2427 right side when truncation=both was in effect.
2429 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2432 --- 2.0.23 2004/08/11
2434 Fix buffer overrun in CQL parser when dealing with proximity (%).
2436 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2437 to UTF-8/UCS conversion is now only based on codetables.xml.
2439 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2441 --- 2.0.22 2004/08/06
2443 Add support for more "commit changes" in ZOOM (uses Extended Services).
2445 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2448 Yet another small fix for configure of SSL.
2450 --- 2.0.21 2004/05/14
2452 Fix SSL libs for configure when --with-openssl=DIR is given.
2454 --- 2.0.20 2004/05/10
2456 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2458 SSL comstack now uses yaz.pem certificate file on server side
2459 by default. Certificate filename can be configured by calling
2460 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2462 Fix bug regarding multiple calls to ZOOM_connection_connect.
2464 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2466 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2467 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2469 ZOOM now allows inspection of X509 peer certificate for verification.
2470 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2472 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2473 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2474 as "modular" but it simplifies things.
2476 Added cs_get_peer_certificate to that returns peer X509 PEM.
2478 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2479 NULL if SSL is unavailable.
2481 Documentation about MARC decoding tools.
2483 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2485 --- 2.0.19 2004/03/30
2487 Rename CHANGELOG to NEWS to follow GNU style packing.
2489 Fix bug with missing initialization of member in init_diagnostics.
2490 This bug affects threaded version of GFS server.
2492 --- 2.0.18 2004/03/20
2494 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2497 Ensure zlib.dll is packed with Windows install.
2499 --- 2.0.17 2004/03/17
2501 Fix encoding of xsd:string to use text instead of CDATA.
2503 Fix endless loop in CQL parser with unbalanced ".
2505 Use a more compact way to store MARC-8 conversion tables.
2507 --- 2.0.16 2004/03/16 Debian only
2509 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2512 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2517 --- 2.0.15 2004/03/01
2519 Another fix for decoding of XML packed records.
2521 --- 2.0.14 2004/02/25
2523 Fixes for Chunked encoding. White space not ignored after length spec.
2525 Update NS and use default NS for SRW diagnostic elements.
2527 --- 2.0.13 2004/02/23
2529 Implement ZOOM_resultset_cache_reset which resets record cache.
2531 Implement ZOOM_resultset_sort which sorts a result set.
2533 Implement chunked HTTP transfer.
2535 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2537 --- 2.0.12 2004/02/16
2539 Added member 'schema' to bend_explain_rr structure so that backend
2540 can specify explain record identifier. Defaults to Zeerex 2.0.
2542 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2544 --- 2.0.11 2004/02/16
2546 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2549 Added init command for yaz-client which sends "extra" init request.
2551 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2552 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2554 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2556 Make ZOOM error code for "invalid query".
2558 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2560 --- 2.0.10 2004/02/05
2562 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2565 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2567 Added option -p <file> to make Generic Frontend Server to write PID file.
2569 Added option -D to put Generic Frontend Server in background on its own.
2571 Make ZOOM C recognize option "password". If unset, "pass" is used
2572 (for backwards compatibility).
2574 Fixed a bug in Generic Frontend Server that could make it crash if a
2575 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2578 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2579 Must be issued before open, in order to be in effect.
2581 --- 2.0.9-6 2004/01/12 Debian/Windows
2583 Make the SRU server more picky WRT unknown params, etc.
2585 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2587 New YAZ client command, options, that sets Z39.50 options.
2589 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2590 options from a string of tokens (one token for each option bit).
2592 Update SRW diagnostic code messages.
2594 --- 2.0.9-5 2004/01/07 Debian/Windows
2596 Handle user defined stylesheet for SRW/SRU.
2598 --- 2.0.9-4 2004/01/06 Debian/Windows
2600 Fix bug in decoding of Content-Length.
2602 --- 2.0.9-3 2004/01/06 Debian/Windows
2604 Fix a bug with decoding of XML packed records.
2606 --- 2.0.9-2 2004/01/05 Debian only
2608 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2610 Fix bug in SRW/SRU diagnostics decoding.
2612 --- 2.0.9 2004/01/05
2614 Fixed bug in Generic Frontend Server which could drop records exceeding
2615 preferred message size. Reported and fixed by Irina Dijour.
2617 Fixed calculation of package size for structured records in Generic
2618 Frontend Server. Reported and fixed by Irina Dijour.
2620 Fixed namespace for SRW/SRU diagnostics.
2622 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2624 --- 2.0.8 2003/12/22
2626 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2627 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2630 CQL changes to reflect recent changes to the specification:
2631 * Documentation talks about context sets instead of index sets.
2632 * Documentation talks about indexes instead of qualifiers.
2633 * The CQL-to-PQF transformer's configuration file now uses
2634 "index.set.name = <attributes>" instead of the old form
2635 "qualifier.set.name = <attributes>". (Both forms are still
2636 understood but the latter is deprecated.)
2637 * CQL terms with no explicit index specified are now interpreted as
2638 cql.serverChoice instead of srw.serverChoice (which of course
2639 behaves exactly the same.)
2641 --- 2.0.7 2003/12/16
2643 MARC conversion can now generate ISO2709 output in another
2644 character set. yaz-marcdump uses this facility if you invoke it
2647 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2648 functions from there can be used from C++.
2650 --- 2.0.6 2003/12/04
2652 Frontend server now transfers memory from decoded packages to stream
2655 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2656 references to show up.
2658 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2659 the ZOOM Abstract API. The older names for the same options are still
2660 also supported for the benefit of old applications.
2662 ZOOM-C supports "implementationId" and "implementationVersion" options
2663 to go along with "implementationName". These allow the user code to
2664 specify identification strings to be sent to servers.
2665 Add OID for the new ExtLite attribute set.
2667 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2668 as requested/supplid by Ere Maijala <ere@atp.fi>
2670 For generic frontend server, reverse the order of
2671 "toolkit-supplied / application-supplied" strings sent as implementationId,
2672 Name and Version. Also, remove the spaces around the slash. This brings
2673 the GFS in line with the behaviour of ZOOM-C on the client side.
2675 Add function ZOOM_scanset_display_term.
2677 yaz-client shows scan displayTerm if present.
2679 Utility yaz-iconv is now installed by default along with the man page
2682 Extend configure check for OpenSSL to use pkg-config where available (such
2685 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2686 server to specify uid/gid/mask for socket using the format
2687 unix:[user=uid,][group=gid,][umask=mask,]file=path
2688 If file= is omitted the existing format is assumed, e.g.
2690 in which case the mask is 0666 (rw for everybody).
2692 Major restructure of YAZ source. All source in libyaz is in src directory.
2693 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2694 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2696 Added man page for utility yaz-marcdump (used to be called marcdump).
2697 yaz-marcdump is installed by 'make install'.
2699 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2700 of incoming package failed.
2702 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2704 Change prototype of odr_perror: add const to message string.
2706 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2708 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2709 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2710 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2711 DNS lookup. There should not be any compatibility problems with this
2712 assuming that blocking=1 or 0 is used.
2714 Fix bad reference in UNIX comstack in function cs_addrstr.
2716 Fix for compilation on AIX.
2718 The generic front-end server (server/seshigh.c) now supports returning
2719 Init diagnostics to the client in User-information-field, in
2720 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2723 --- 2.0.4 2003/09/04
2725 Allow any CQL relation (not just all,any,exact,scr).
2727 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2728 that features the same UI.
2730 Implemented command update0 in YAZ client which is equivalent to
2731 update but uses old of Ext Update ASN.1.
2733 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2734 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2735 Previously no OID was used for this info.
2737 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2738 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2739 returns 'malformed search term' otherwise.
2741 SortResponse member resultCount now set to NULL in sort handler of
2744 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2747 Add three new utility functions for translating OIDs between various
2748 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2749 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2750 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2751 char *oid_to_dotstring(const int *oid, char *oidbuf);
2752 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2754 Reverted modifications for ES Update definition for z_IU0Update
2755 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2756 is back to YAZ 2.0.2.
2758 String value attributes for CCL parser.
2760 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2761 which their FirstSearch server returns in Init responses, sometimes
2762 carrying useful diagnostic information when Init fails. This has the
2763 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2764 "z39.50/oclcui.asn", where its definition is somewhat different from
2765 what OCLC document on their web-site, as required to interoperate with
2768 Support for anonymous authentication in yaz-client. Use the command
2771 * Fix the OID of the Index Data-local "admin" Extended Service from
2772 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2773 the 1000, which indicates a locally-defined OID, was a mistake.
2775 --- 2.0.3 2003/06/20
2777 Fix CCL directive @case handling so that it affects string match for
2778 both CCL keywords and qualifiers.
2780 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2781 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2782 Decoder has been updated with ASN.1 changes as listed in
2783 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2784 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2785 z_IUUpdate, remains unchanged.
2787 ZOOM_record_get may now return a record in a specific character set.
2788 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2789 "from" is the character set of record as returned by target. "to" is
2790 the character set to be returned. If omitted, "to" is UTF-8.
2792 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2794 New ODR utility, odr_getelement, which returns name of element for
2795 which encoding/decoding failed.
2797 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2798 in cases where a required element was omitted.
2800 Bug fix: some MARC8 sequences were not converted.
2802 New ZOOM option "step" which specifies number of records to be
2803 retrieved in one chunk. Used in conjunction with "start" and "count".
2805 SRW support for yaz-client. Use scheme http: to use it, e.g.
2808 yaz-client no longer does (un)intelligent character set conversions
2809 by default. Can be enabled with charset and marc_charset commands.
2811 xmalloc trace fix for 64-bit systems such as DEC alpha.
2813 Solaris 2.6 compile fix.
2815 New function, cql_strerror() translates SRW error codes, as returned
2816 by cql_transform_error(), into human-readable English strings. Used
2817 in yaz-client diagnostics when appropriate.
2819 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2820 converts it into a type-1 query which is sent to the server. This
2821 makes CQL available for use with all Z-servers, as opposed to the tiny
2822 minority that can handle CQL queries themselves.
2824 --- 2.0.2 2003/04/28
2826 New Debian package layout similar to the Redhat Package layout.
2828 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2829 and search result respectively.
2831 --- 2.0.1 2003/04/25
2833 Redhat package is now several packages: libyaz (runtime libraries),
2834 libyaz-devel (development and documentation, and yaz (utility programs).
2835 Package spec file by Morten Bogeskov.
2837 New member 'schema' in struct bend_fetch_rr which the name of requested
2838 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2839 handler MAY set this to reflect the schema of the returned record.
2841 New member 'display_term' in struct scan_entry. GFS now sets member entries
2842 and allocates scan entries to be filled by user scan handler. In previous
2843 version, entries member was allocated by the scan handler. That still works,
2844 but the GFS will ignore member display_term - assuming it was NOT set by
2845 the handler. The fact that the GFS now allocates the entries both allows
2846 for new members and makes a scan handler easier to write.
2848 Fix CQL lex buffer overflow.
2850 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2851 SRU default recordPacking is string.
2853 SRU protocol support for frontend server.
2855 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2857 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2859 Added scan for the ZOOM shell (zoomsh).
2863 * String Identifers for Schemas (Amendment 5).
2864 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2865 Old definition for schema
2866 Odr_oid *schema; /* OPT */
2871 Z_InternationalString *uri;
2872 #define Z_Schema_oid 1
2873 #define Z_Schema_uri 2
2876 * resultCount parameter to Sort Response (Amendment 1).
2877 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2879 Support for SRW 1.0 over HTTP. This is an optional feature and
2880 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2883 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2884 on the same port. SRW SearchRetrieveRequests are mapped
2885 to bend_init,bend_search,bend_fetch,bend_close.
2887 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2889 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2890 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2892 ZOOM connections are SRW based if schem http is used for hostname
2893 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2894 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2896 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2897 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2898 distance=n, order=true/false, relation=le, prox unit=word. If
2899 n is omitted, distance 1 is used.
2901 Fixed problem with C compiler include path in wrong order.
2903 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2904 on Solaris. Patch from Ko van der Sloot.
2906 New MARC decode API. All new functions operate on a yaz_marc_t
2907 handle. The most important new functions are: yaz_marc_create,
2908 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2909 decode and destroy respectively. Decoder can produce formats
2910 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2911 include/yaz/marcdisp.h.
2913 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2914 to UTF-8, UCS-32, wchar_t or Latin-1.
2916 * Prototypes for yaz_iconv_-functions moved to separate header
2917 include/yaz/yaz-iconv.h.
2919 Make a few private functions 'static' in unix.c. This prevents
2920 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2922 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2923 are set when Init Response is received.
2925 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2926 but returns diagnostic set as well.
2928 New function yaz_strerror which is a portable wrapper for
2929 strerror/strerror_r/GetLastMessage.
2931 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2932 is returned for MARC. If type is "oai", then OAI MARC is returned.
2934 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2937 --- 1.9.2 2002/11/26
2939 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2941 Fix bad race conditions on SIGTERM and terminate gracefully in
2944 Move retrieval (data1) module to Zebra since nobody seems to be
2947 Add GRS-1 render for ZOOM using same format as yaz-client.
2949 --- 1.9.1 2002/10/05
2951 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2953 Fix broken ESpec handling in data1 module.
2955 SGML reader parses comments and makes them part of the data1 tree.
2957 Added several type casts so that YAZ compiles as C++ code.
2959 ZOOM didn't handle PDU encoding failures properly.
2961 Added more Bib-1 diagnostics (approved extensions).
2963 GNU configure: better check for iconv.
2965 More portable use of accept, getpeername. Check for socklen_t. Use
2966 int/size_t if socklen_t is not defined.
2970 PQF parser rejects bad queries - including those with extra
2971 characters in them. PQF parser used to silently ignore that.
2972 Cleaner API for PQF added, which allows you to get detailed
2973 error information for bad queries (see yaz/pquery.h).
2975 Fixed bug in ZOOM_record_get for type "database".
2977 Implemented mini iconv library supporting conversions between
2978 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2980 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2982 --- 1.8.9 2002/08/20
2984 Fixed ZOOM C record cache so that preferredRecordSyntax and
2985 elementSetName is used to check for already fetched records.
2987 --- 1.8.8 2002/08/02
2989 Added three members in bend_initrequest structure to facilitate
2990 character set negotiation.
2992 Fixed a bug in frontend server that could cause indefinite
2993 loops under rare conditions.
2995 Revised character set utilities (charneg.h) so that encoding
2996 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2998 For PQF, directive @term <type> sets term type for Scan/Search.
2999 Here <type> is general, string, numeric, null. The term type
3000 is inherited - just like @attr.
3002 New call odr_set_charset that sets character set conversion for
3003 international-strings on a ODR stream. Prototype is:
3004 int odr_set_charset(ODR o, const char *to, const char *from);
3005 The InternationalString is still represented as C string in YAZ
3006 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3007 won't). On the protocol level, you can use any encoding.
3009 Support for UNIX sockets in ZOOM.
3011 Solaris recv sometimes returns errno == ENOENT. It is treated as
3012 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3014 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3015 both client and server. Code by Morten Bogeskov.
3017 --- 1.8.7 2002/05/22
3019 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3020 that they can be used directly from Visual Basic. You must recompile
3021 your windows APP if you're using ZOOM.
3023 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3024 Commands "lang" and "charset" sets language and character set respectively.
3025 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3026 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3028 Attributes from multiple CCL fields may be OR'ed rather than merged
3029 using directive "@field or". Fields are still merged by default -
3030 equivalent to "@field merge".
3032 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3035 Fixed bug in zget for parameter ExtendedServicesResponse.
3039 --- 1.8.6 2002/03/25
3041 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3043 Client displays USR.1:SearchResult-1 (hits per term).
3045 Additional Search Info for search in Generic Frontend Server.
3047 Fixed CCL parsing of "field=s".
3049 WIN32 installer - using the excellent NSIS software from nullsoft.
3051 Fixed CCL parsing of "field = - <number>".
3053 Added function yaz_marc_decode that decodes MARC for line mode
3054 display or XML (similar to that used by JZKit).
3056 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3057 Z39.50. But ISO/ILL was, however.
3059 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3060 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

3065 --- 1.8.5 2002/02/03
3067 New YAZ client features: Command completion and new commands:
3068 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3069 Code provided by Jacob Poulsen.
3071 New call oid_trav, that visits all registered OIDs via callback.
3073 Function ZOOM_record_get now returns const char pointer rather than
3074 void pointer. It saves a lot of type casts.
3076 For YAZ client, command "auth" now allows you to set authentication
3077 in IdPass style. It is enabled when three tokens are given - order
3078 is user, group and password.
3080 Fix memory leaks in MARC record handling for ZOOM.
3082 New option for YAZ client, -k <kilobytes> that sets
3083 maximum record size. Similar to -k option for generic frontend
3084 server and yaz-ztest.
3086 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3088 Prefix query parser reports "fail" when bad attribute set is given.
3090 Fix in MARC decoder. Proximity logging. Fix for attribute set
3091 in scan handler for server. Patches by Shigeru Ishida.
3093 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3096 Configure option --with-openssl=<dir> now works when a directory is
3097 specified. Patch provided by Morten Bogeskov.
3099 New option for YAZ client, -u <auth>, that sets authentication.
3101 ZOOM fix: error information was sometimes "missing", since error
3102 was cleared/reset too when it shouldn't.
3104 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3106 --- 1.8.4 2002/01/04
3108 Scan for ZOOM API. New object ZOOM_scanset. New functions
3109 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3110 ZOOM_scanset_destroy.
3112 New ZOOM function, ZOOM_connection_last_event, that returns type
3113 of last event (such as "receive data", "send data", "apdu received",
3116 New ZOOM option, schema, that specifies schema for retrieval.
3118 New CCL feature. Qualifiers can be aliases for one or more
3119 other qualifiers (if more than one is given, OR is used).
3121 ZOOM uses named result sets if target supports it.
3123 Two new YAZ client commands: . (dot, which sources a script of YAZ
3124 client commands), and ! (to execute shell command.). Implemented
3127 Working on Debian packages.
3129 --- 1.8.3 2001/11/19
3131 YAZ client enables named result sets only if target supports it.
3133 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3135 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3136 with key="host" to get same result.
3138 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3139 Function Z3950_resultset_record(s) returns references to records
3140 "owned" by resultset. To become owner use Z3950_record_clone.
3142 Function z_ext_record handles Extended Services. Thanks to
3145 --- 1.8.2 2001/11/12
3147 CCL Parser fix: ignore token comma when dealing with and-lists.
3149 Documentation updates for COMSTACK.
3151 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3152 Changed prototype Z3950_records. For some functions, int parameters
3153 were changed to size_t.
3155 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3158 New MARC decode/display function, marc_display_exl, which properly rejects
3159 non-ISO2709 records. YAZ client uses it.
3161 --- 1.8.1 2001/10/29
3163 Fix bug: local attribute set wasn't set correctly in PQF strings.
3167 * Old Z39.50 codecs no longer supported.
3169 Added ZOOM C binding. See http://zoom.z3950.org/
3171 Renamed states for COMSTACKs to avoid confusion with events.
3173 Implemented cs_look and proper cs_rcvconnect.
3175 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3177 Configure detects POSIX threads on OpenBSD.
3179 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3180 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3182 When error is returned from present handler, non-surrogate diagnostic
3183 is returned in present response (and fetch handler is no longer called).
3185 * Minor adjustments to pquery parser (PQF). Token characters may be
3186 escaped by using backslash (C-style).
3188 PQF parser allows string attribute values to be specified. For @attr,
3189 non-numeric characters after the equal-sign are treated as strings
3190 (e.g. @attr 9=title).
3192 CCL trunction character may be defined (@truncation in file)
3194 * function zget_ExtendedServicesRequest sets waitAction to
3195 waitIfPossible (was wait).
3197 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3200 CCL operator names may be set in field definition files (CCL_bibset).
3201 See ccl/bib1 for an example.
3203 Fixes in ASN.1 compiler for C++ compatibility.
3205 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3206 and "op_or" to avoid conflict with C++.
3208 Fixed problem with GNU readline detection on Redhat 7.0.
3210 Added step-size for Scan backend handler.
3212 Fixed bug that made the frontend server crash when no attribute
3213 set was specified for scan.
3215 Front-end server automatically switches to original working directory
3216 when installed as an NT service. Previously -w had to be specified to
3219 Added extended attributes for retrieval module (data1), so that data1
3220 records carry d1_readXML/SGML attributes. d1_read also supports
3221 null-data rules ( <tag/>)
3223 On UNIX when POSIX threads are available, a separate library libyazthread
3224 is created. Programmers should link with that library and the yaz library
3225 when using threads. The reason for the split was that some applications
3226 on Linux, such as Apache, doesn't work well when using shared objects that
3229 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3230 (or any frontend server) in SSL mode by specifying ssl: followed by
3231 address. Only tested on UNIX.
3233 Added feature for CCL module. Virtual structure s=al or s=ol generates
3234 and-list and or-list respectively instead of phrase search.
3238 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3239 log_mask_str. This was done to avoid name conflicts with other libraries
3240 (such as other PHP extensions).
3242 Added raw OID member for preferred record syntax (request_format_raw)
3243 and returned record syntax (output_format_raw) for backend fetch method.
3245 Config file yaz-config now accepts options so that it returns specific
3246 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3248 Shared library support for UNIX using GNU libtool.
3250 * Modified backend interface. Request/Response struct's replaced by
3251 one read/write C struct. For example bend_fetchrequest and
3252 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3253 Every handler - even search has to be registered in bend_init
3254 handler. This means that the YAZ library no longer refers to
3255 external functions and it makes it possible to make the whole
3256 thing a single DLL/SO.
3258 Added Segment handler for backend server.
3260 Added Zmbol/Zebra administrative functions to YAZ client.
3262 Threaded frontend server on UNIX (when POSIX Threads are available).
3263 Starting the server with option -T enables multi-threading.
3267 Added configure option --enable-comp/disable-comp to control use
3268 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3269 located in sub directory asn.
3271 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3272 in ${exec_prefix}/bin along with the other programs yaz-client and
3275 GNU automake used to maintain makefiles.
3277 Added several OID's.
3279 Changed retrieval module so that we can load records with no abstract
3280 syntax defined. Tagpaths in these records are fully composed of string
3283 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3287 On UNIX, the generated makefile now supports a proper 'make install'.
3288 The prefix can be set via GNU configure to set the install location
3289 (default is /usr/local).
3291 * YAZ programs client and ztest were renamed to yaz-client and
3292 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3293 locations, such as /usr/bin,/usr/local/bin,etc.
3295 * YAZ Header files were moved from include to include/yaz. YAZ Header
3296 files are referred to as include <yaz/log.h> rather than <log.h>.
3297 The YAZ include path (-I ..) is therefore the same as before. Programmers
3298 should update their #include statements or use -Ipath/include/yaz
3299 instead. The main motivation for doing this change is that YAZ header files
3300 can be installed in "standard" locations /usr/include,/usr/local/include
3301 without introducing conflicts, since ALL YAZ header files are stored
3302 in subdirectory yaz (under /usr/include for example).
3304 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3305 rather than project/workspace files. We switched because project files
3306 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3309 Changed name of logging function, logf, to yaz_log, to prevent name
3310 clash with some math-log functions. The YAZ header log.h defines logf
3311 to yaz_log (#define) so there should be no incompatibilities by this
3314 Added bend_start/bend_stop handlers for server. These handler are
3315 called on start/stop of server. For windows they are called whenever
3316 a service is started/stopped.
3318 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3319 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3320 in util/yc.tcl. The auto-generated C code structures are, in a few
3321 cases, incompatible with the old decoders. There are differences in the
3322 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3323 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3324 The preprocessor variable ASN_COMPILED is defined when the compiled
3325 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3326 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3327 wish to use the old encoders/decoders you can specify --disable-yc
3330 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3331 version so that it supports both new - and old version of DB Update
3333 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3334 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3335 change. The name parameter can be set to 0 in which no name is specified
3336 for the construction. The macros odr_implicit and odr_explicit sets name
3337 parameter to zero for the construction involved. New macros
3338 odr_implicit_tag and odr_explicit_tag are similar to the others,
3339 except that a name parameter is added. For programmers' that don't use
3340 ODR they probably only need to change the call to z_APDU and z_External.
3342 Added access control facility by interfacing the TCP wrapper library.
3343 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3344 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3345 name of the daemon and enables the access control as specified in
3346 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3348 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3349 den Dool <H.M.vdnDool@kub.nl>.
3351 Added reference ID parameter to most functions in server API - refer
3352 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3354 Changed name of ccl library to libccl.a (was ccl.a).
3356 Fixed bug in decoder for Explain (Category TargetInfo).
3358 Added support for GNU readline in client. Thanks to Jacob Poulsen
3359 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3361 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3362 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3363 IMPLEMENTATION! This change was made to the development version before
3364 the ZIG decided to retract the amendment. If any users MUST be
3365 compatible with the original Update definition, PLEASE CONTACT US, and
3366 we will include a separate definition corresponding to the old Update
3367 ES. Note that because of the change to the ASN.1 of the
3368 TaskPackageRecordStructure we cannot define a single structure that
3369 will support both versions.
3371 * Added const modifier to buffer parameter for some ODR/BER encoding
3372 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3373 completeWAIS, odr_dumpBER.
3375 Fixed bug in client.c which caused a crash when a scanResponse didn't
3376 contain positionOfTerm.
3378 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3379 * will cause an error in a client if a non-YAZ target sends both a
3380 * list of Scan entries and non-surrogate diagnostics.
3382 Retrieval module enhancements. Tag sets may be typed in the reference
3383 to it. From the .abs-file the "tagset" directive takes a third optional
3384 integer type for the tag set referenced. From a .tag-file the "include"
3385 directive takes a third optional type as well. The old "type" directive
3386 in the tag set itself is still recognized but acts as the default type
3389 Backend interface change. Individual Scan terms returned from bend_scan
3390 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3391 in include/backend.h.
3393 Retrieval module enhancements. Multiple tag sets and attribute sets may
3394 be specified in abstract syntax specs. Revised the error/warning for
3395 logging messages reported by the retrieval module when reading the
3398 Object Identifier system (oid_..) changed. The API is backwards
3399 compatible but the oid-routines now allocates new OID's when needed.
3400 Raw OID's may be specified in oid_getvalbyname.
3402 YAZ now uses GNU configure to generate Makefile(s).
3404 * Minor changes in some of the member names of DeleteResultSetRequest and
3405 DeleteResultSetResponse. See include/proto.h.
3407 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3408 and added member 'languages' in TargetInfo (which was missing).
3410 Changed the way attribute sets are handled in the retrieval
3411 module. These are now cached, just like the abstract syntaxes
3414 Changed YAZ so that it links with compiled ASN.1.
3416 Added Explain-schema definitions and mapping routines. The following
3417 Explain categories have been implemented: AttributeDetails,
3418 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3420 Fixed minor bug in Windows version of Server Library.
3422 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3424 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3426 Added EXTERNAL: UNIverse Resource Report (non-standard).
3428 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3429 ENUMERATED and SET OF.
3431 * Added 'const' to some of the char pointer arguments for the
3432 functions, data1_read_node, data1_getelementbytagname,
3433 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3436 Fixed bug in data1_insert_taggeddata - the last_child member of
3437 parent wasn't initialised.
3439 * Changed data1_read_record and data1_read_node so that the supplied
3440 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3441 doesn't refer to any parts of the "SGML"-buffer.
3443 Fixed bug in server library (Windows version of statserv_remove).
3445 * Changed code so that it compiles as C++. The type definition
3446 of Odr_fun which is a member of Odr_arm was changed. The result is,
3447 that an explicit typecast is needed for the fun pointer when
3448 using Odr_arm - as in:
3449 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3451 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3453 Implemented the new structured date and time definition as approved
3454 by the ZIG. Added schemaId element to the specificTag in Espec-1
3455 (also approved at the last ZIG). Thanks to RVDM.
3457 Added some Object identifiers (RVDM).
3459 Changed the Update Extended Service (RVDM).
3461 Added command "refid" to client which specifies referenceId for
3462 the following requests.
3464 Implemented extended service handling for server. See ztest.c
3465 for an example as well as backend.h. New handlers are registerd
3466 in the Init handler.
3468 * Changed interface for sort in server.
3470 Added new members to statserv_options_block. It allows a server
3471 to read options from another source than just the command line. Thanks
3472 to Charles Woodfield.
3474 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3475 renamed to zboolean. Some C++ compilers complained about the name.
3477 Minor changes to gils.abs. Added index 's' (sort) on title
3478 and date/time-last-modified.
3480 --- 1.4pl2 1998/1/30
3482 Fixed bug in server library regarding inetd mode (-i). This bug
3483 was introduced by release 1.4.
3485 --- 1.4pl1 1998/1/29
3487 Added sort facility in client and backend server interface.
3489 Fixed problem with dependencies in Makefile(s).
3491 Fixed bugs for encoders/decoders of extended services and
3494 Implemented sub-tree feature for schemas. Sub-trees are
3495 referenced in *.abs-files. See explain.abs for an example
3496 of the use of this feature.
3498 Modified bib1.att; local attributes for ANY didn't include
3499 ANY itself (only affects use of the retrieval module).
3501 Fixed bug in plain SGML reader in function data1_read_node:
3502 tags with prefix "var" was incorrectly interpreted as variants.
3504 Added feature "sub-schemas" to enable references to - and definitions
3505 of - group of elements.
3507 * Removed member parent from type data1_element (in data1.h).
3509 Implemented function odr_nullval() that returns the value of
3512 * Removed member num_children from data1_node (in data1.h).
3514 Made NT service interface part of the server library. The
3515 function statserv_main uses the NT service when required and
3516 calls the statserv_start / statserv_close routines.
3518 Routine zget_SearchRequest and zget_PresentRequest fills
3519 resultSetName/Id member with "default" instead of "Default".
3521 Fixed memory leak in server. Request queue member wasn't freed.
3523 Fixed nmem_exit so that memory is freed.
3527 Revised the CCL parser utility to be thread safe.
3529 Added function, oid_ent_to_oid, to replace the function
3530 oid_getoidbyent, which is not thread safe.
3532 * Added nmem_init and nmem_exit to initialize and release
3533 NMEM resources. Function nmem_init should be called once in the
3534 initial thread before NMEM/ODR is used. statserv.c and client.c
3535 have been changed accordingly. The change was necessary to make
3536 NMEM thread safe. The NMEM memory pool is shared amongst threads
3537 in a process. Unix-based applications will still work fine without
3540 Added NT Services interface for the the Z39.50 (statserv) Server.
3541 Refer to the ztest.c source on the usage.
3543 Windows 95/NT port using MSVC5.0. Project files are included in the
3546 * Defined new 'global' handle for the retrieval (data1) system. The
3547 new handled, data1_handle, describes the state of the data1 system.
3548 This handle is passed as first argument to virtually all
3549 data1 related routines. The functions data1_create and data1_destroy
3550 creates and destroys a data1 handle respectively.
3552 Added ODR encode stream member to all backend request structures
3553 init, search, scan etc. This stream should be used to allocate all
3554 memory used for the response when thread safe operation is needed.
3556 Changed the comstack utility, cs_addstr, to be thread safe. The
3557 returned hostname string returned by the function is now part the
3560 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3561 function. The cs_straddr takes a COMSTACK handle as argument, so this
3562 function must be used after cs_create and before bind/connect.
3563 This function is thread safe.
3565 Moved test server to 'ztest' directory - generic server code still
3566 in 'server' directory.
3568 Made prefix query (pquery.c) utility thread safe.
3570 Added new function modifier YAZ_EXPORT to 'export' public DLL
3571 functions when using windows (see include/yconfig.h).
3573 Added definitions to the OID database (util/oid.c) (RVDM).
3575 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3577 Added call to ccl_rpn_delete in client program.
3579 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3580 release of RPN structure.
3582 Added support for C++, headers uses extern "C" for public definitions.
3583 With input from RVDM.
3585 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3586 Thanks to Ronald van der Meer (RVDM).
3588 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3590 Added support for private extensions to the OID database
3591 (oid_setprivateoids()). Thanks to RVDM.
3593 Added optional, physical ANY (key replication)
3595 Fixed null-reference problem in GRS-1 output filter.
3597 Proximity operator added to Prefix Query Format (PQF).
3599 In test client command "base" accepts multiple databases.
3601 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3605 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3607 Smallish bug-fixes in the new encoders/decoders (explain).
3609 Bug fixed in DeleteRequest.
3611 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3613 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3615 Added SOIF syntax (using private OID for now) to retrieval module and client.
3617 Added Update extended service.
3619 Added SearchResult-1 additional info structure.
3621 Added optional CCL (ISO8777) interpreter as separate module. Available
3624 --- 1.2 1996/6/10 (1st anniversary release)
3626 Added Summary record syntax. Lightly tested.
3628 Added OPAC record syntax. Untested.
3630 Added ResourceReport service encoders/decoders. Untested.
3632 Fixed bug in z_Unit - wrong tagging on unitSystem.
3634 Fixed bug in the DiagRecs decoder.
3636 Added options for max PDU size and session timeout to frontend-server.
3638 Added documentation of query-language parsers and other supporting utilities.
3640 [frontend-server] Added Attribute set to the bend_scanrequest API.
3642 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3643 surrogate diagnostics were generated.
3645 [retrieval] Allow multiple local values for attribute.
3647 [retrieval] Allow multiple attributes per element in .abs files. index type.
3649 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3651 --- 1.1pl2 1996/4/10
3653 Minor changes, mostly specific to Zebra's requirements (retrieval)
3657 Repaired bug in frontend server when running multiple listening
3658 endpoints in dynamic mode.
3660 z_External() now won't break if a known, ASN.1 value comes encapsulated
3661 in an octet-string. The value will pass through unmodified in an Odr_oct.
3663 Added a bit of code to the demo client to decode & display
3664 ASN.1-structured records represented in the octet-aligned branch of
3665 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3667 Added z_ext_getentbyref() to the ASN module. Doc updated.
3669 * Completed the SCAN definition in the ASN module. This may break SCAN
3670 code based on older YAZ-versions at compile-time. The fix is easy -
3673 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3674 under the SCAN definition. Remember to initialize this, server-people.
3676 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3677 that this does not extend to ODR and ASN.
3679 Comstack allows insertion of established socket (primarily for
3680 inetd-operation of servers). Doc updated.
3682 Front-end server can now start from the inetd in TCP mode. Doc
3685 --- 1.0pl4 1996/1/24
3689 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3690 the rank and record number.
3692 Adjustments to the frontend server.
3694 Fixed diagnostic BER dumper. It ignored the file argument.
3698 Various changes to retrieval module.
3700 Changed the union discriminators of the protocol files from enums to
3701 ints paired with #defines.
3703 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3706 *Changed operator in the RPN structure to 'roperator', again to avoid a
3709 Fixed problems in Explain decoders/encoders.
3711 --- 1.0pl2 1995/12/6
3713 Memory bug in log module fixed.
3715 --- 1.0pl1 1995/12/5
3717 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3719 Bug in Explain DatabaseInfo module fixed.
3721 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3725 The shift to v1.0 signals that we now consider the *core* functionality
3726 of YAZ reasonably stable (the core being more or less equivalent to
3727 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3728 tested (Explain not at all - though that will happen soonish).
3730 Minor changes to code to support Windows port.
3732 Various minor changes after we're getting to use GRS-1 & co. more.
3734 Added Espec-1 format.
3736 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3737 of the protocol and it cannot be selected when encoding (maps into 'string'
3738 when decoding). Needed to talk to some servers.
3740 Demo client can request simple element set names.
3742 Added Diagnostic Format encoders/decoders.
3744 Added simple Close handling to frontend server (no hooks for resource
3745 reporting yet), and demonstration client.
3747 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3749 --- 1.0b3 1995/08/24
3751 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3752 handled incorrectly when records were requested in the searchResponse. This
3753 will only affect you if you use the frontend-server.
3755 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3756 Test-client will ask for and print GRS1. Ztest will return dummy records
3759 Added Explain encoders/decoders to the service-level API. Untested.
3761 Added Extended Services: Item Order encoders and decoders to the Service-
3762 level API. Untested. We could use a recent copy of the pertinent bits
3763 of the ILL protocol to add those bits.
3765 Added diagnostic format 1 encoders/decoders to the service-level API.
3768 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3769 odr_cons.c, which causes a more correct output.
3771 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3772 was always set to 0 when no records were requested in the searchRequest.
3774 * Added better external-handling. This shouldn't harm old code that
3775 *encodes* externals. It can break code that looks for a
3776 'single-ASN1-type' representation, since those types that are known
3777 are now decoded immediately. Look at the SUTRS sample code in
3778 seshigh.c and client.c. Documentation updated.
3780 Handling of structured records in bend_fetchresponse. Length -1 marks
3781 structured record, type is deduced from format field.
3783 --- 1.0b2 1995/06/27
3784 Fairly quick maintenance release to add SUTRS support.
3786 Fixed handling of SUTRS records in the demonstration client.
3788 * Added format field to the bend_fetchrequest and bend_fetchresponce
3789 structures of the backend API (frontend server). When the record is
3790 returned, the value of the format field is mapped to an OID. The
3791 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3792 of the record. The special value VAL_NONE in the bend_request means
3793 that no specific format was requested by the client. Documentation
3794 updated accordingly. Test server (ztest) will return a fixed dummy
3795 SUTRS record if your client requests SUTRS.
3797 Documentation updated accordingly.
3799 You can now set external libraries and RANLIB support in the top-level
3803 First public release.
