3 Improve error reporting for ICU chains YAZ-707
4 Report config element+rule when ICU status is "failure".
6 ZOOM: stop fetching if present response has no records YAZ-710
7 Some targets return less records than their hit count would suggest.
8 This prevents ZOOM from continuing to fetch records if any present
9 response has 0 records in the response.
11 Ensure that GFS calls exit if any listener fails YAZ-710
12 Before, if XML config was in use, it would start the default
17 yaz-ztest: -V shows version (like yaz-client -V)
19 New iconv encoding: danmarc YAZ-692
21 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
23 daemon: only wait for immediate child rather than all children. YAZ-704
25 yaz-client: fix setting of SRU record schema. If scheme was unset, it
26 could lead to invalid memory reference.
30 yaz-ztest returns schema for MARCXML test records. SRU require that
31 recordSchema for records.
33 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
34 instead of non-surrogate diagnostic. This is a per-record failure.
36 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
37 may refer to multiple listeners now. Attribute listenref is a comma separated
40 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
41 option is given for GFS, the dirname of filename (for -f) is used
42 as prefix for options such as cql2rpn, ccl2rpn, etc.
44 Content-Type charset fixes YAZ-701 . Do not inspect charset in
45 Content-Type header for SOAP when decoding SRU. The payload (XML)
46 itself tells what encoding it is. In response, never supply encoding
47 in Content-Type. The response payload (XML) tells what it is (with no
48 encoding in XML it's UTF-8).
50 HTTP decoding: allow blanks in URL paths YAZ-700
54 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
55 and facets. Ensure recordData and recordSchema are always present in
56 record element, because they are required.
58 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
61 Simplify in a lot of places using odr_strdupn.
63 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
67 Increase various buffers in GFS's statserv_options_block
68 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
69 This change makes many type-casts redundant, and, thus simplifies code.
71 Remove last bits of WAIS support.
73 Remove member 'size' from Odr_oct.
75 Slim down the public part of 'struct odr'. Most elements are not part
76 of struct Odr_private.
78 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
79 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
80 In particular facets are supported in both client - and server side.
81 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
82 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
83 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
84 both request/response). This is what a search handler in the GFS
85 will see (regardless of whether operating in SRU mode or Z39.50).
87 Changes to the srw.h (SRU/Solr) definitions include:
88 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
89 (char*), which replace union query and query_type (int). This is because
90 SRU 2.0 supports a queryType parameter. This also means that, to carry
91 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
92 x-pquery=PQFstring (extention parameter). The extension parameter
94 - New element, packing, that has information about SRU
95 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
97 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
99 New element, packing, in Z_SRW_explainRequest.
101 New elements in Z_SRW_scanRequest, queryType and scanClause.
102 These replace query_type and scanClase untion. This is similar to what
105 --- 4.2.69 2013/10/01
107 GFS: log when closing down - at least SIGTERM YAZ-684
108 Also change formatting WRT PID logging a bit.
110 Improve display of MARC records with multi-byte subfield IDs YAZ-695
111 In some rare cases subfield identifiers are multi-byte characters.
112 This will try to deterime length of those and split accordingly.
113 This affects display in line mode as MARCXML/MarcXchange. The encoding
114 of ISO2709 is the same.
116 Change inp argument to const for yaz_read_UTF8_char.
118 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
120 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
122 Better check of marc leader info YAZ-691
123 Problem is that some systems generate MARCXML/MarcXchange with
124 funny headers. These will not work if encoded as ISO2709.
125 Some tests produce new output, due to updated warning messages
127 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
129 yaz-client: display MAB records YAZ-689.
130 Thanks for Heiko Jansen for this patch.
132 New utility z_get_HTTP_Response_server which allows both HTTP server name
133 and HTTP server URL to be given in response.
135 Debian: do not depend on obs tcl8.3.
137 Debian: do not depend on obs libicu36-dev.
139 --- 4.2.68 2013/09/23
141 GFS: pass additionalSearchInfo to search memeber search_input if
142 given. Otherwise pass otherInfo. Request for facets and other search
143 related things will be passed there in future versions of YAZ.
145 New ZOOM setting, authenticationMode, which allows authentication
146 paramters to be encoded in the URL rather than via HTTP Basic auth.
149 rpn2solr: fix nested AND/OR handling. YAZ-685
151 Add comparison routines for some Z-types, such as NamePlusRecord,
152 RPNQuery, Query, RecordComposition and OtherInformation.
154 --- 4.2.67 2013/09/19
156 Don't decode MAB as MARC. Just like we don't attempt to decode
157 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
159 CCL: allow quoted terms for date ranges. YAZ-681
161 Introduce ccl_parser_qual_search. This function makes old function
162 ccl_qual_search, from YAZ 2, available again.
164 Add yaz_facet_list_to_wrbuf. YAZ-683
166 --- 4.2.66 2013/09/11
168 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
169 schema was given for search. YAZ-675
171 Add Solr date range searches. YAZ-621
173 --- 4.2.65 2013/08/22
175 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
177 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
179 ISO2709/MARC parse most octet aligned records; not just those that
180 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
181 MARC parse more records instead of just dumping as is. YAZ-670
183 ZOOM: proper caching for variations of record schema. YAZ-671
185 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
187 --- 4.2.63 2013/07/17
191 --- 4.2.62 2013/07/11
193 New utility z_get_HTTP_Response_details - an extended version of
196 New utility yaz_url_get_error which returns error message of last
197 failed yaz_url_exec call.
199 yaz-url and url functions: allow max HTTP redirects to be controlled.
201 New functions yaz_file_glob2, yaz_xml_include_glob.
202 These functions takes a flags parameter, which, for now only controls
203 whether to fail inclusion of a non-existing file (without glob
204 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
206 --- 4.2.61 2013/06/20
208 For MARC XML parsing, allow record without leader. A fake/default leader
209 is inserted and a warning is tagged with the record.
211 ICU: fix leak in in icu_iter_get_org_info.
213 --- 4.2.60 2013/06/14
215 ICU: fix bug in icu_iter_get_org_info (un-init variable).
217 --- 4.2.59 2013/06/11
219 Implement z_HTTP_header_remove.
221 --- 4.2.58 2013/06/11
223 ICU: Disallow 0 ptrs for some ICU string utilities.
225 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
226 returns original tokens (before normalization).
228 CCL: avoid z39.58/regex truncation when not needed. Apply only the
229 conversion of those masks, when absolutely necessary.
231 CCL: configurable masking character - @mask. Default masking character
234 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
235 full response anyway, so a Transfer-Encoding header will obstruct the
238 --- 4.2.57 2013/05/15
240 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
241 picking a socket. Problem is that some systems has IPV6 support, but
242 we can't create sockets for them, so we pick AF_UNSPEC first.
244 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
245 use content_len to determine resulting Content-Length in HTTP response
246 and NOT Content-Length supplied in headers by user.
248 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
249 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
251 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
254 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
255 with big endian and unsigned char (by default).
257 --- 4.2.56 2013/04/26
259 Fix yaz-client connect (crash in 4.2.55).
261 --- 4.2.55 2013/04/26
263 Fix proxy/host problem for ZOOM that could occur if unix sockets
266 New Debian package libyaz4-dbg.
268 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
269 differently in tcpip_close.
271 --- 4.2.54 2013/04/17
273 Windows installer of YAZ includes YAZ4J as a component.
275 CQL: allow "extra terms" again, by default. Thus, the CQL parser
276 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
277 and earlier. CQL parser may operate in strict mode where queries
278 not conforming to the standard BNF are rejected (syntax error).
279 Whether the CQL parser operates in strict mode is controlled with
280 cql_parser_strict . Strict mode enabled with option -S for utilities
281 cql2pqf and cql2xcql .
283 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
285 --- 4.2.53 2013/04/10
287 New charset, MARC-8c, which is like MARC-8 but allows control characters
288 0x01 through 0x1F, except ESC to be passed through verbatim.
290 Fix a problem with duplicate sub field character in MARC output. Problem
291 happened only when output was MARC-8 encoded.
293 --- 4.2.52 2013/04/03
295 yaz-ztest: Use hash for fake hit count. Before, random number was used.
296 This is problematic for unit tests using yaz-ztest. This patch also makes
297 a hash for CQL queries. For RPN, any term with a leading digit will be
298 treated as pseudu hit count (to force any particular hit count by a client).
300 yaz-ztest: return unique MARC dummy records. Beyond record offset
301 24, the author surname is patched with offset to make all records
304 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
305 on system wide default (/proc/sys/net/ipv6/bindv6only).
306 @4 binds to IPV4 only. @6 binds to IPV6 only.
308 Update CQL API documentation a bit
310 CQL: don't accept extra terms for queries. Makes the CQL parser
311 stricly conformant to the standard.
313 --- 4.2.51 2013/02/12
315 GFS: scan handler gets extra_args from request and may return extra
316 response data . That's for SRU only.
318 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
320 --- 4.2.50 2013/01/30
322 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
324 OPACXML: sync spelling of availabilityDate in XML to that of Schema
325 opaxxml.xsd. The schema had the correct spelling of this member always.
326 The ASN.1 was mis-spelled and still is (API change) - we are
327 not changing this. However, the OPAC to XML conversion had yet
330 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
333 New function, z_ext_record_oid_nmem, which is similar to
334 z_ext_record_oid but takes NMEM rather than ODR
336 --- 4.2.49 2013/01/18
338 ICU: New conversion element 'join' which joins tokens into one
339 with a custom character given by rule attribute.
341 --- 4.2.48 2013/01/10
343 New GFS search member: present_number. This is a hint to the
344 search handler how many records are going to be fetched immediately
345 following search. There's no guarantee that it's going to be the case,
346 since it depends on hit count (for Z39.50 piggyback) and whether errors
349 Make a few functions static (private). The functions getbyte_stream,
350 ungetbyte_stream and yaz_gets are now private. They were never declared
353 yaz-marcdump: exit(5) for serious decoding errors
355 ISO2709 decoding: be more picky WRT header
357 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
358 was only used as to indicate that next-result-set-position should be
360 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
361 Based on patch from Ashley Sanders.
363 Make some functions static/private in PQF parsing. Those functions were
364 never declared in a public header and so should not be in use by
365 applications based on YAZ.
367 --- 4.2.47 2012/11/23
369 ZOOM: special options to control APDU logging.
370 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
371 logging of APDUs until "saveAPDU" option is set again. If logging is
372 already enabled the effect is that current APDU buffer is cleared.
373 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
374 logging (default behavior on new connection).
375 The APDUs sent/received can be obtained by using
376 Using ZOOM_connection_option_get(c, "APDU") or
377 ZOOM_connection_option_getl(c, "APDU", &l).
379 GFS: relay implementation_version from backend
380 From 3.0.40 and later, implementation_version from backend was
381 not used in init response at all.
383 --- 4.2.46 2012/11/15
385 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
386 mode at all. Probably never did.
388 Make a new version of ztest.pem that, at least, is not expired.
390 --- 4.2.45 2012/11/13
392 Fix description of CCL directive 'case'.
394 More tight checking of form arguments (yaz_uri_to_array). Makes
395 YAZ better at rejecting big and/or bad POSTs.
397 SRU decoding does not report more than up to 10 invalid arguments.
399 rpn2cql: less quotes in generated terms. Semantics unchanged, but
400 it's prettier this way.
402 --- 4.2.44 2012/10/25
404 New utility yaz_decode_init_diag. Defined in proto.h.
406 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
407 given for unix local socket.
408 The COMSTACK string for doing so is:
411 unix:/myfile:tcp:localhost:9999/mybase
412 unix:/myfile:localhost:9999/mybase
413 unix:/myfile:http://fakehost/mybase
415 debian: Use dpkg-buildflags in build process.
417 --- 4.2.43 2012/10/19
419 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
420 global's SRU service uses a recordPosition scheme starting from zero.
421 First record's position should be one
422 according to the standard.
424 --- 4.2.42 2012/10/18
426 Allow more namespaces for SRU. This is to allow, for example, an
427 incorrect namespace returned from server
428 http://services.igi-global.com/sru .
430 Minor fixes for compilation on Windows.
432 --- 4.2.41 2012/10/11
434 daemon: log total number of bad signals from child on stop so that it
435 is more easy to spot problems with child worker processes.
437 retrieval: empty backend name attribute omits element set
438 from being used in retrieval.
440 --- 4.2.40 2012/10/04
442 Implement Solr sort strategy "solr", similar to sru11 sorting.
443 This will implement the correct parameters on Solr requst to do
446 --- 4.2.39 2012/09/28
448 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
451 MARC: Extra/missing indicator handled for MARCXML.
452 The indicator length is given in header and is the same for the
453 whole record. If attributes ind1, ind2 are missing, then content
454 character defaults to blank. Extra indicator attributes (beyond)
455 indicator length are treated as an error.
457 Reformat: delete trailing whitespace
459 --- 4.2.38 2012/09/17
461 MARC: fix non-ASCII characters for leader. This is to ensure we can
462 generate XML in UTF-8.
464 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
465 in one node with structure word.
467 --- 4.2.37 2012/09/04
469 yaz-json-parse: JSON output may be pretty printed by using option
472 Increase default value of max message for Z39.50 Init for GFS, ZOOM
473 and yaz-client. Old value was 1 MB. New value is 64 MB.
475 --- 4.2.36 2012/08/22
477 yaz-client: don't display bogus records from SRU servers. Some SRU servers
478 return more records than given by *maximumRecords*. Skipping those in
481 record_render: simplify buffer return handling and fix at least one bad
482 memory reference, that broke the test_embed_record sometimes.
484 Allow http://user:pass@host notation for yaz_url_exec.
486 zoomsh: allow shell command to be executed. Via the system(3) call.
488 yaz_poll: Allow num_fds == 0
490 yaz-client: fix bad encoding of "itemorder item". The itemorder
491 item <no> - command forgot to use length of encoded Item Request
492 package. Error present since YAZ 3.
494 yaz-ztest: fix bad usage of session handle. Bug was introduced when
495 result sets were saved (271a9c83).
497 SRU recordPacking: guess record packing in response rather than looking
498 at the recordPacking element which, OF COURSE, changed semantics in SRU
501 Decode SRU 2.0 responses. The official namespace for responses, according
502 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
503 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
504 nature.com's server, however, usee namespace
505 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
506 we are now using a glob-expr to match up the namespace. ZOOM C and
507 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
508 I can not find a single real example showing the "real" namespace in
509 the documentation from OASIS. The namespace for requests is different
510 from responses, but this is not added to YAZ yet, when we don't encode
513 --- 4.2.35 2012/06/26
515 zoom/record_render: add support for Base64 decoding fo MARC records
516 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
517 which will decode base64 + ISO2709 marc-8 encoded material from text node
520 --- 4.2.34 2012/06/07
522 Add missing definitions ZOOM_resultset_get_facet_field_by_index
523 and ZOOM_resultset_facets_names.
525 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
528 Change APDU dump printing to avoid long leading blanks. For levels 16
529 or larger the level is shown and the indentation is truncated but
530 recursed with modula 8. This makes it still reasonable easy to read
531 - even for nested BER dumps.
533 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
534 return 0 (incomplete package) in case where the BER package was
535 considered too nested (return value of -2).
537 dumpber: lines of level 15 are not indented further. Two spaces per
538 indentation; indentation 15 or more is indented to a fixed indentation
539 and augmented with a level=<no> indication.
541 zoomsh: increase max size of command+args
543 GFS: No limit in RPN buf size in CQL to RPN conversion.
545 --- 4.2.33 2012/05/09
547 New function for daemon utility, yaz_daemon_stop .
549 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
551 --- 4.2.32 2012/04/25
553 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
554 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
556 --- 4.2.31 2012/04/23
558 YAZ daemon utility relays SIGUSR1 to child process.
560 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
561 would result in en empty database list - which in turn would result in
562 encoding failure for search.
564 Fix reading beyond string in yaz_sort_spec.
566 --- 4.2.30 2012/04/11
568 Add two new SRU diagnostics:
569 236: Access to specified database denied
570 1015: Init/AC: Maximum number of simultaneous sessions for Userid
572 Document the very useful ZOOM-C option "apdulog".
574 CQL to RPN: term may be passed through verbatim. This is enabled with
575 truncation.cql . The assumption being that the term is already CQL.
577 --- 4.2.29 2012/03/20
579 record_conv: leader spec may be given for marc element.
580 The leader spec is given as attribute leaderspec for element marc.
581 For example to convert a MARC21 record from MARC-8 to UTF-8:
582 <marc inputformat="marc" outputformat="marc"
583 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
585 record_conv: allow user-XSLT params. For example:
586 <xslt stylesheet="MARC21slim2DC.xsl">
587 <param name="myparameter" value="myvalue"/>
588 <param name="otherparameter" value="othervalue"/>
591 record_conv: fix error handling for missing marc charsets.
593 CQL: fix extra terms in wrong order.
595 --- 4.2.28 2012/03/06
597 record_conv: modify new API for conversion types. The conversion types
598 may be passed in new functions yaz_record_conv_configure_t and
599 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
601 Avoid mixed statement/variable declare; fixes compilation with Visual
604 --- 4.2.27 2012/02/28
606 Add non-standard SRU diagnostic: 235: "Database does not exist".
607 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
608 Update SRU to Bib-1 diagnostic maps accordingly.
610 CCL: add two new diagnostics for unsupported masking. The new
611 diagnostics are: "Embedded truncation not supported" and
612 "Single charcacter mask not supported".
614 --- 4.2.26 2012/02/23
616 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
618 --- 4.2.25 2012/01/11
620 Build YAZ for Ubuntu Oneiric.
622 CCL: allow parantheses for proximity operands. For example CCL query
623 (a) % (b) is now allowed.
625 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
626 marked dead, rather then being destroyed. If not, the session memory is
627 being free'd before the search/scan handler is finished. Also destroy
628 'request' memory in request_release rather than in various places,
629 which resulted in leaks from time to time.
631 --- 4.2.24 2011/12/21
633 cql_sortby_to_sortkeys: honor sort prefix.
635 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
636 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
637 The rpn2cql family of functions now always returns quoted CQL terms.
639 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
641 --- 4.2.23 2011/12/15
643 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
644 sequence is treated as one. For example, &&a=b&&&c& is identical to
647 --- 4.2.22 2011/12/05
649 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
650 APDUs for a connection to a WRBUF.
652 --- 4.2.21 2011/11/23
654 Fix cql_sortby_to_sortkeys. Completely broken before.
656 Make CCL's @truncation work again.
658 --- 4.2.20 2011/11/09
660 New ZOOM connection setting: tproxy. It's like proxy, but does not
661 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
662 to set resolved address + port for a connection outside ZOOM itself.
664 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
666 --- 4.2.19 2011/11/07
668 Fix uninitialized variable in Solr spell support (could cause SEGV
669 for SRU response decoding).
671 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
672 back-end's addinfo through into the ZOOM response addinfo.
674 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
675 they are separated by a colon and a space rather than simply
678 --- 4.2.18 2011/10/28
680 Add support for Solr spell-checking/suggestions through ZOOM.
681 If a Solr target has been configured correctly for spelling-checking
682 and suggestions, these will now be returned on the ResultSet option
683 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
685 --- 4.2.17 2011/09/28
687 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
688 with a flag whether to substitute escape sequences or not.
690 --- 4.2.16 2011/09/22
692 Fix nmem_strsplit_escape to substitute escape char properly.
694 New option for zoomsh -e , which makes it abort on first error and
695 return process exit code to indicate success/failure.
697 YAZ options utility supports special option -- which makes all it treat
698 all following arguments as non-options.
700 --- 4.2.15 2011/09/16
702 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
703 searched if absolute filename is given.
705 Fix conv_xslt() error-reporting when stylesheet is not found.
706 (The value of fullpath is meaningless in this situation.)
708 --- 4.2.14 2011/09/07
710 Fix problem in CQL sort node creation: un-initialized memory.
712 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
713 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
714 CQL sortby depending on whether Type-1 or CQL is actually sent to the
717 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
718 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
720 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
721 will make it possible to use both single-character mask (#) and wildcard (?)
722 in CCL . Throw diagnostic for left truncation because that is not supported
725 --- 4.2.13 2011/09/01
727 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
728 cases using escapes (\-sequences) and masking.
730 PQF parse fix: A trailing backslash followed by end-of-string (\0)
731 would result in a read one byte beyond string.
733 rpn2ccl may use Z39.50 masking for terms (t=z).
735 ICU check fix. Don't include library -lCrun on Solaris, unless present.
737 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
738 not --cppflags (which seeems like an error in icu-config).
740 --- 4.2.12 2011/08/27 RPM package only
742 cql2ccl: fix conversion of terms: operator characters were not
745 --- 4.2.11 2011/08/25 RPM package only
747 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
748 CCL parser will map both # and ? to their regular expression
749 quivalents (. and .*).
751 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
752 of reserved CQL characters.
754 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
755 is, so that they are passed through.
757 --- 4.2.10 2011/08/24
759 ZOOM SRU mode: more aggressive re-connect.
761 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
762 made available as a utility function, declared in <yaz/logrpn.h>
764 rpn2cql_structure() supports proximity nodes (except that the Type-1
765 proximity node's "exclusion" binary is ignored, as there is no way to
766 express that in CQL). Fixes bug #4564.
770 Fix SEGV that could occur if set command of zoomsh was given without
771 value (2nd argument).
773 Fix SEGV that could occur if unsupported transport was given for
774 COMSTACK - say https (when SSL was unavailable).
776 Build yaz-url on Windows too.
780 New utility to get web content. Header is url.h. A command line tool
781 yaz-url is part of the distribution and packages.
783 Fixes for SSL COMSTACK (when gnutls is in use).
785 New functions yaz_base64{encode,decode}. Header is base64.h.
789 ZOOM C includes HTTP response buffer as additional info if it fails
790 to decode the SRU response.
792 Make wrbuf_json_puts available.
796 zoom: throw diagnostic for invalid value for option "sru". Before a
797 bad SRU request was sent.
799 Adding new utility wrbuf_vp_puts.
801 Add cclxmlconfig.obj to win/makefile. It was missing completely.
805 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
806 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
807 redirect was used at the same time.
809 MARC line mode decoding: be less picky about length given - first
810 5 digits of header that is.
812 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
814 Changes to decoding of SRU records: a record with recordPacking=xml is
815 modified with a new root element <yaz_record> if the recordData contains
816 multiple children elements. This is to make the record XML parseable
819 RPN to Solr conversion: encode special characters.
821 Generic Frontend Server: fix uinitialized member, stepSize.
825 Fix a bug in SRU decoding of records.. The database records stored
826 had un-initialized memory, but it would only be seen with yaz_record_render
827 and type_spec="ext" .
829 Fix a bug in ccl_qual_dup introduced in 4.2.3.
833 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
837 Add new utilities to convert from CQL to CCL . These utilities have
838 prefix cql_to_ccl defined in cql.h.
840 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
841 lead to memory heap corruptions when ICU utilities were in use.
845 Make compilation work without Libxml2.
847 yaz-client: remove redundant blanks in display of searchResult-1 term
852 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
853 resulting CQL node (tree) in a new node CQL_NODE_SORT.
855 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
856 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
857 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
858 Note that the CQL sortby spec is only converted when the GFS is already
859 converting from CQL to RPN (cql2rpn element).
861 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
862 specify whether to collapse delimitors or not. The existing nmem_strsplit
863 do collapse (collapse parameter = 1).
865 Windows installer: For NSIS, set InstallDir depending on x86/x64.
867 Rename internal func yaz_use_attribute_create. While non-static, this
868 function is not declared in a public header.
872 Add -lCrun when linking with ICU on Solaris.
874 More quicks character set conversions for OPAC records.
878 fix problem with record_render: records were converted (character set
879 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
883 SRU: add methods for handling DADS SRU-proxy facets.
885 Separate OPAC record character set for ZOOM_record. yaz_record_render
886 allows a character set given as charset=from/opacfrom,to where 'from' is
887 the character set of a bibliographic record, 'opacfrom' is character set
888 of OPAC record and 'to' is the target character set.
892 yaz-client: show may XML format records. Command show followed by 'format'
893 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
896 src/stemmer.c: Avoid using unnamed union. It is not supported by some
899 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
902 Update yaz.spec to operate on both SLES11 / Centos 5.5.
904 RPM: Release includes 'indexdata' name. Use indexdata in release name so
905 this package can be distinguished from other vendors.
907 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
908 as determined by configure
910 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
912 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
913 returns no error and no record, the present request is considered
914 partial (only a subset of the records could be returned by backend), and
915 so it is appropriate to set Present Status to partial-4.
919 Move yaz-config man pages to section 1.
921 More documentation about Solr.
923 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
924 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
925 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
926 peers on some Linux systems. However, in general that does not work
927 so YAZ can not rely on that to work. Debian changed behavior in this
928 respect from Debian lenny to Debian squeeze (still testing as of Oct
930 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
932 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
936 Fix yaz-config output: echo_source not set correctly by configure.
940 Solr Web Service support for yaz-client and ZOOM.
942 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
944 --- 4.0.12 2010/08/17
946 Z39.50 facet support. Facet specifications are passed for search in
947 other-information with ASN.1 as defined in facet.asn and OID
948 .10.1000.81.5 . Facets are expressed as an Attribute list as known
949 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
950 3 is limit (number of entries to get in response). yaz-ztest returns
951 dummy facets if a client asks for them.
953 --- 4.0.11 2010/07/09
955 CCL fixes: bug 2895 and bug 3539.
957 GR1-display: add comma in display - was removed by mistake in
960 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
962 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
964 --- 4.0.10 2010/06/18
966 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
967 result set from a connection. The result set will be on its own
968 thereafter; no operations on it will perform retrievals from a target.
969 Only cached copies are returned.
971 ZOOM C:fix case for HTTP servers responding with Connection:close.
972 Ensure that if there is a current task it is resumed (like fetching
973 more records in a result set) . Bug #3484.
975 PQF parser: use odr_atoi for Odr_int (not atoi)
977 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
978 values that contain any non-digits are treated as string attributes
979 (previously decoding only checked for leading character ([0-9]). PQF
980 encoding: attribute string values are not surrounded by double-quotes.
984 New utility for managing threads - thread_create.h.
986 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
987 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
988 but YAZ' implementation do.
990 Fixes for yaz_cond-functions on Windows 7.
992 DLL export more symbols.
994 zoomsh: show record do NOT render opac.
996 Remove *.la files from Debian and RPM packages.
1000 Debian package libyaz-dev depends on libgnutls-dev again (was
1001 removed in YAZ 4.0.6, but due to Libtool it is still needed
1002 even though yaz-config do not list libgnutls libs).
1004 ZOOM: Use only one WRBUF for returning string results for
1005 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1007 ZOOM: ZOOM_connection do not use a shared pointer to
1008 ZOOM_resultset after ZOOM_resultset is destructed by
1009 user. Reverts to YAZ 4.0.4 behavior.
1011 --- 4.0.7 2010/05/04
1013 record-conv: fix problem with at least one XSL conversion -
1014 due to probably incorrect usage of XML XSL documents.
1016 --- 4.0.6 2010/04/29
1018 Fix yaz-config for static mode and the use of SSL (gnutls).
1020 --- 4.0.5 2010/04/29
1022 Forward decl timeval struct in mutex.h and gettimeofday.h.
1024 yaz-config: fix 'static' mode linking.
1026 --- 4.0.4 2010/04/28
1028 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1029 are wrappers for pthreads or Windows. For Windows these are put in
1030 a separate DLL: yaz_cond4.
1032 libyaz.la (whole source) is compiled with thread. If thread support
1033 is enabled enabled, all source of YAZ is compiled with treading support.
1034 This allows core utilities such as yaz_log to use thread facilities.
1035 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1036 thread utilities. This commit moves mutex utilities (mutex.c) from
1037 libyaz_server.la to libyaz.la.
1039 yaz-json-parse displays leading text until error.
1041 --- 4.0.3 2010/04/09
1043 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1044 patch from Giannis Kosmas.
1046 SRU: no longer URL encode SRU database. The URL for an SRU server is
1047 a URL and such is alreeady encoded - at least when given with leading
1048 http:// or https://. This reverts behavior to YAZ 3.0.50.
1050 Support for new MARC XML notation TurboMARC which like MARCXML is a
1051 complete representation of MARC/ISO2709.. This one, however, is more
1052 compact and allows for faster processing with XSLT. TurboMARC can be
1053 used in the marcdisp.h API, from the yaz-marcdump utility and from
1056 yaz-ztest can be configured - via the database - to perform certain
1057 delays when it performs operations search, present and single record
1058 fetch. This allows testers to make yaz-ztest act as a real or even slow
1059 Z39.50 server. Refer to the yaz-ztest man pages for details.
1061 --- 4.0.2 2010/03/09
1063 wrbuf_destroy allows NULL WRBUF passed to it.
1065 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1067 Add ZOOM_connection_close.
1069 No fixed size buffers for ZOOM shell - bug #3257.
1071 tstodr: make it work on s390 platform.
1073 New icu iterator-functions. The new icu_iter-functions makes it possible
1074 to use ICU chains from many threads.
1076 yaz-client: better syntax check for show command.
1078 --- 4.0.1 2010/01/26
1080 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1083 New simple local-file XML include facility which allows file glob-patterns.
1084 Refer to yaz/xml_include.h.
1086 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1089 ZOOM_record_get supports new parameter "format" which makes it format XML
1092 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1093 JSONText in ECMA-262) is JSONValue, not JSONObject.
1095 --- 4.0.0 2010/01/20
1097 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1098 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1100 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1101 POSIX/Unix builds .so with major version 4.
1103 Remove old LOG_-defines from log.h. They have been obsolete and
1104 undefined by default for the last 5 years.
1106 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1108 GFS: Remove socket (int *fd) from search_rr handler. The socket
1109 descriptor ptr is a facility that allowed a search handler to supply
1110 a socket which would serve as a callback - when search was complete.
1111 This facility has now been in use for years.
1113 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1114 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1115 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1116 returns 'const char *' rather than 'char *. The returned string is
1117 read-only and should not be modified by applications. COMSTACK cs_close is
1118 now a void function - it no longer returns int. No applications check for
1119 the value and the implementations has always returned 0.
1121 ZOOM: use size_t for scan hit counts and str size. Functions
1122 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1123 occ (hit count) and len (string length) are now of type size_t pointer
1124 rather than int pointer. This is to be able to represent large hit counts
1125 and to also just to use the proper type for string length (strlen result).
1127 New JSON parser. Refer to include/yaz/json.h .
1129 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1130 Used to be int in some cases. Many wrbuf_-functions used to return an int
1131 indicating some length.. These return values were never used. And so they
1134 ODR: odr_malloc, odr_total now takes size_t for size.
1136 clone_z_type: fix leak; occurred for encoding failures.
1138 --- 3.0.52 2009/12/03
1140 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1141 bug was introduced in 3.0.51.
1143 --- 3.0.51 2009/12/02
1145 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1147 tcpip comstack: fix leak for getaddrinfo.
1149 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1150 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1151 Decoding of SRU "path" database is performed by private function
1152 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1153 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1155 yaz-client: honor base command for SRU. Change when database setting
1156 is applied for SRU and ensure it is kept when a connection is reset.
1157 Change also the way errors are displayed or SRU (decoding of packages).
1159 --- 3.0.50 2009/11/02
1161 Add support for extra request / response data for SRU codecs and GFS.
1162 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1163 for extra data response buffer and length. For the GFS, both request
1164 and response data (XML) is carried in extra_args and extra_response_data
1165 for the search handler. Patch by Ko van der Sloot.
1167 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1168 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1169 10010). This fixes bug #2113.
1171 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1172 cmdfile included a 'quit' command that would result in a memory violation.
1174 --- 3.0.49 2009/10/01
1176 Make a number of functions defined in xmlquery.c static. These have
1177 never been declared in a public header file (yaz/xmlquery.h) and was
1178 made public by mistake.
1180 Improve speed of character conversions (iconv utilities). This makes
1181 conversions from MARC-8 faster.
1183 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1184 unless type desired is "raw". This will prevent type "xml" from
1185 returning ISO2709 .. Which obviously can not be XML parsed.
1187 Fix memory leak in ZOOM that would occur if option apdulog was used
1188 on a re-used connection.
1190 Frontend server logs HTTP requests.
1192 Frontend server now sends Z39.50 close when it times out (sesssion has
1193 been idle for too long). Versions 2.0.30 and earlier also sent close.
1194 But due to a mistake this was disabled in all versions after that, i.e.
1195 the server would just close the socket immediately.
1197 yaz-client emits a better message when receiving an unrecognised
1198 userInformationField.
1200 Skip zero-length subfields when decoding ISO2709. This rare case happens
1201 if a record has two FS characters in a sequence. Without this patch
1202 there would be a reference beyond char array in using_code_len fragments
1205 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1207 --- 3.0.48 2009/08/28
1209 The show command offered by the zoomsh command now takes a 3d optional
1210 parameter type which is what is passed to ZOOM_record. If the type
1211 argument is omitted, "render" is used.
1213 RPN to CQL conv may use USE string attributes (bug #2978).
1215 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1217 --- 3.0.47 2009/07/08
1219 Function yaz_xml2query allows a diagnostic element in the PQF XML
1220 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1221 code and additional info respectively.
1223 The BER BOOLEAN is now the integral type Odr_bool which still happens
1224 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1225 typedef'd to Odr_int. This is still an integral 'int', but it may be
1226 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1227 ASN-1 compiler as well as programs has been updated to use the new types.
1229 --- 3.0.46 2009/06/08
1231 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1232 only the bibliographic record was rendered. For type=opac, an OPAC
1233 record is only returned if it is present.
1235 iconv: small fix for encoding of advancegreek.
1237 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1239 yaz-client: option auto_reconnect=on really reconnects.
1241 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1243 server: avoid null ptr ref for for yaz_poll errors.
1245 build: fix RPM build for RHEL 5.3.
1247 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1249 --- 3.0.45 2009/03/31
1251 Fixed bug #2709: TCP connect returns Invalid argument.
1253 Fixed compilation for mingw.
1255 Honor charset for raw records (ZOOM_record_get).
1257 Fixed use of errno for threaded mode that was seen on Solaris 10.
1259 Fixed argument passing with blanks in value for Windows Service.
1261 Disable YAZ' own log rotate by default (no 1 GB limit).
1262 The variable l_max_size which specifies the log file limit is set to 0
1263 (DISABLED): This is due to the fact that YAZ is most often deployed using
1264 logrotate. Also YAZ can not perform log rotate because of unsufficient
1265 permissions (setuid).
1267 --- 3.0.44 2009/02/17
1269 List supported encodings in man page for yaz-iconv.
1271 Fixed missing SSL libs for --libs output
1273 Re-established OID record syntax application-xml. Nobody should use it
1274 but we don't want to change soname because of this symbol being absent.
1276 --- 3.0.42 2009/02/02
1278 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1280 Added member named_result_sets for init handler struct for the GFS. This
1281 allows a server to disable named result sets.
1283 Removed OID record syntax application-xml.
1285 Added support for rule-based transliterator for ICU wrapper of YAZ.
1287 Fixed bug #1902: yaz-icu XML output.
1289 Make YAZ checks Emacs friendly.
1291 BITSTRING value shows value. Bug #2346.
1293 ISO2709 decoding: skip control characters from indicator data.
1295 Omit sort key by default in yaz-icu's output.
1297 Allow combined single char options (again) for YAZ' options function.
1299 Utility yaz-marcdump got option to display YAZ version (-V).
1301 Allow YAZ to use ICU 3.4.
1303 Added new ICU test case which illustrates removal of diacritics.
1305 --- 3.0.41 2008/12/29
1307 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1309 --- 3.0.40 2008/12/29
1311 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1314 Fixed bug #2352: yaz-marcdump crashes for certain record.
1316 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1318 Added support for Danmarc2 to UTF-8 conversion.
1320 Added support for ISO5426 to UTF-8 conversion.
1322 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1323 implementation version.
1325 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1327 --- 3.0.38 2008/11/10
1329 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1330 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1332 ZOOM C now interprets databaseName option for ZOOM connection as path
1335 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1337 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1339 Dummy Libxml2 types no longer defined in headers of YAZ'.
1341 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1344 --- 3.0.36 2008/09/26
1346 Various ODR chapter fixes.
1348 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1350 Added missing source for Windows compilation, mutex.c.
1352 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1354 For SRU connections in ZOOM all records up to "count" are now fetched.
1356 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1357 in Windows due to bad error handling for Libxml2.
1359 Added facility for sending arbitrary records (ASN.1 any) using
1360 ZOOM C's Extended service update. Patch by Sam Reynolds.
1362 New options for ZOOM C's connection, logapdu which makes ZOOM log
1365 --- 3.0.34 2008/06/18
1367 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1369 --- 3.0.32 2008/06/12
1371 Fixed memory violation that could occur when decoding UTF-8. This bug
1372 was only present in 3.0.30 of YAZ.
1374 --- 3.0.30 2008/06/06
1376 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1377 GNU TLS is used by default (if found).
1379 yaz-ztest returns OPAC records if a client asks for OPAC.
1381 Improved speed of MARC-8 encoding.
1383 Added support for lossy and loss-less MARC-8 encoding.
1385 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1387 Added new Windows Service wrapper (sc).
1389 yaz-client's itemorder command may now send a file.
1391 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1393 Added new function yaz_log_xml_errors.
1395 Allow (but warn) unknown XML attributes in MARCXML parsing.
1397 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1399 The UTF-8 to MARC-8 conversion now uses a different set of characters
1400 for Greek symbols. Bug #2120.
1402 --- 3.0.26 2008/02/21
1404 Added yaz_daemon (daemon.h).
1406 Fixed bug #2068: pkg-config trouble
1408 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1410 --- 3.0.24 2008/01/28
1412 Document --with-xml2 option.
1414 Added OPAC XML XSD (etc/opacxml.xsd).
1416 Allow glob mask for name attribute in retrieval element for the
1417 generic frontend server's retrieval facility.
1419 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1420 except POLLIN/POLLOUT.
1422 Fixed error handling in cs_listen. Bug #2037.
1424 --- 3.0.22 2008/01/20
1426 Fixed version in yaz/yaz-version.h.
1428 Fixed bug #2027: Crash when closing connection.
1430 Changed configure so that ICU support is only enabled if only ICU
1431 and Libxml2 is available (because the ICU chain is XML based).
1433 --- 3.0.20 2008/01/15
1435 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1436 is built. Only this DLL depends on the ICU runtime.
1438 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1439 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1441 Changed license of CCL module to 'Revised BSD'. After consultation with
1442 remaining members of the original EUROPAGATE consortium, we are re-issuing
1443 the CCL module without a separate license. The software was developed by
1444 Index Data as part of a research project. The special license was included
1445 to help feed usage information back to the project consortium to support
1446 project evaluation. At this time, the project consortium has long-since
1447 disbanded, and the majority of the original principals have retired. At the
1448 same time, we have significantly modified the software during the following
1449 years, to the point where very practically no original code remains. To
1450 simplify re-use of the software, we have contacted those members of the
1451 consortium who could be reached, and agreed to re-issue the module as a
1452 proper part of the YAZ package.
1454 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1456 CQL closer to being version 1.2 compliant. CQL also allows free-form
1457 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1460 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1461 bug could make Extended services handling crash in the ZOOM layer. This
1462 bug was only present in YAZ 3.0.18.
1464 --- 3.0.18 2007/12/19
1466 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1469 yaz-marcdump reads and writes collection wrapped records.
1471 Handle OPAC for record conversion module.
1473 Fixes for ICU wrapper.
1475 Allow ICU libs to be controlled with --with-icu .
1477 --- 3.0.16 2007/11/12
1479 Added yaz_poll which is a wrapper for select/poll. When poll is available
1480 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1481 sockets to be in use.
1483 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1484 functionality through an XML based configuration (ICU chain). This system
1485 is useful for search facilities such as Pazpar2 and Zebra that needs to
1486 perform tokenization of indexed material. The ICU code in a separate
1487 library libyaz3_icu.a.
1489 Added HTTP tunnel facility for COMSTACK, bug #1752.
1490 This is a facility that allows a Web proxy, such as squid, to tunnel
1491 Z39.50 traffic. This facility is "transparent" to must applications
1492 using YAZ. It's enabled by using pseudo transport connect: followed by
1493 the proxy address, followed by command, then follwed by he regular
1494 "virtual" addresss. For example,
1495 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1497 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1499 --- 3.0.14 2007/09/21
1501 Fixed bad memory reference in ZOOM_record - cuased by member not being
1502 initialized. This was a problem only in YAZ 3.0.12.
1504 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1505 fields were not removed.
1507 Changed the way C code is generated from codetables.xml. Made a MARC-8
1508 conversion trie for each characterSet section rather than codeTable.
1509 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1510 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1512 --- 3.0.12 2007/09/12
1514 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1515 from ZOOM_record_error).
1517 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1519 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1521 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1523 Better SRW-to-Bib-1 diagnostic mapping.
1525 ZOOM C and yaz-client announces SRU version 1.2 by default.
1527 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1530 Fixed in yaz_sru_decode to allow other version than 1.1.
1532 --- 3.0.10 2007/08/22
1534 Added support for SRU scan for ZOOM.
1536 Added support for the use of the older versions or Extended Service
1537 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1538 set to the version , 1=first, 2=second, 3=third. The third version is
1539 what ZOOM C has used so far. And that, obviously, is the default.
1541 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1542 therefore in Zebra and in SimpleServer-based applications). The new
1543 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1544 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1545 which is passed into the back-end search callback function.
1547 Added support for HTTP Basic authentication in clients: the SRU/W
1548 codec encodes the username/password elements of the PDU structure
1549 appropriately, and these may be set using the "user" and "password"
1550 options in ZOOM-C applications (the same options that are used for
1551 Z39.50 authentication).
1553 --- 3.0.8 2007/06/25
1555 Fixed bug #1208: SSL appears to be broken in ZOOM.
1557 Fixed bug #1206: Libxml2 include path weirdness.
1559 Added oid_name_to_dotstring.
1561 Allow elementSetName to be specified for ZOOM C record update.
1563 Allow waitAction to be specified for ZOOM C based for Extended Services.
1565 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1566 syntax OID. Bug introduced in YAZ 3 series.
1568 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1570 --- 3.0.6 2007/06/06
1572 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1573 directory. yaz-client now reads commands from file given by option -f
1574 if specified; then tries to read .yazclientrc in current directory.
1575 Failing that, it reads .yazclientrc from user's home directory.
1577 Added support for correlationInfo Note and ID for Record Update via
1580 Added yaz-client command querycharset which specifies character set for
1581 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1582 (termListAndStartPoint).
1584 Charset ISO5428:1984 is an alias for ISO5428-1984.
1586 Implemented a way to perform scan in a result set using Z39.50. This
1587 is achieved by attaching the result set name in the characterInfo
1588 (type InternationalString) of OtherInformation in the Scan Request PDU.
1589 The result set is identified in the otherinformation by the new OID:
1590 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1591 This allows for scan in result set and faceted search . Zebra did some
1592 of this in the APT term using attribute type 8 and value being result
1593 set. Using the OtherInformation approach for this is cleaner and easier
1594 to work with in proxies and the like. This facility can be used in
1595 yaz-client using new command setscan which takes a result set as first
1596 argument, start position (APT) as second.
1598 Changed decoding of SRU XML packed records to deal with servers that
1599 have recordData with XML data with multiple root nodes. Also make
1600 comparison for recordPacking case insensitive. Again, one server
1601 returns "XML" where others return "xml".
1603 For SRU responses allow Content-Type application/xml as well as text/xml.
1605 --- 3.0.4 2007/05/21
1607 Fixed bug in character set conversion of BER strings. Bug introduced
1610 --- 3.0.2 2007/05/08
1612 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1614 For OID class, use oid_class consistently.
1616 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1619 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1620 character set for bibliographic information interchange". By Giannis Kosmas.
1622 Added documentation on new OID API.
1624 --- 3.0.0 2007/05/02
1626 Changes to generic frontend server interface: added new member
1627 'query_charset' for bend_initrequest structure. A backend init handler
1628 should set this member to its native character set for query terms.
1629 When defined, the frontend server logic will announce this character set
1630 to a client if the negotiationModel bit is set by the client. All server
1631 implementors are encouraged to specify this. If a backend server does not
1632 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1634 Added CCL utility to remove terms (stop words) from resulting RPN
1635 tree. This is handled by functions with prefix ccl_stop_words_ .
1637 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1638 terms in RPN queries.
1640 Clean-up the CCL API. Moved some internal structures from ccl.h to
1641 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1642 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1643 This is replaced by ccl_parser_find_str which takes a string instead.
1645 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1646 libyaz.la is the core of YAZ except the generic frontend server and
1647 does not depend on POSIX threads anymore. libyaz_server.la is the
1648 generic frontend server facilities and uses POSIX thread functionality
1649 if available. The libyaz.la no longer depends on POSIX threads because
1650 the number of global structures is limited. NMEM no longer re-uses blocks
1651 between threads ; it simply free's memory immediately but allocates in
1652 "large" chunks as usual. We don't expect any performance penalties
1653 because of this. The yaz_log system is still using a global log_level so
1654 caution must be taken when modifying it with yaz_log_init_.. +
1655 yaz_log_mask_str. This, however, should not cause any trouble because
1656 these functions are called during initialization of application code
1657 anyway. `yaz-config --libs server` returns libs for server applications;
1658 `yaz-config --libs` returns libs for non-server applications.
1660 New OID database - with public definitions in oid_db.h. Removed old OID
1661 database including the head oid.h and definitions such as enum oid_value
1662 and struct oident. The new OID database uses the same string names as
1663 before but the 'protocol' is gone. There are now only two representations
1664 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1665 converts from string to OID; functions with prefix yaz_oid_to_string
1666 converts the other way.
1668 Change to emit_term() in CQL-to-PQF query translation: when a term has
1669 the /regexp relation modifier, do not process it for leading and
1670 trailing "^" and "*", which have quite different meanings in regular
1673 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1674 write handlers no longer carries a 'last' parameter. This will make
1675 yaz_iconv flush "less" characters. A flush is performed by call to
1676 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1678 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1679 removed, because function yaz_query_to_wrbuf does the same.
1681 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1682 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1684 Deprecated MARC utility functions removed.
1686 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1689 Branch split: YAZ_2_1_55_branch
1691 --- 2.1.54 2007/03/16
1693 Fix to ZOOM-C so that transparent reconnection is properly handled on
1694 connections that are in asynchronous mode.
1696 Fixed compilation on OpenBSD 4.0.
1698 Large strings in GRS-1 records are now properly displayed in yaz-client.
1700 Added character conversion support for "advancegreek"; based on patch from
1703 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1704 sequence is met. Before the error was not set so it would be unknown.
1706 Adjust yaz-marcdump MARC reader so that it skips until record separator
1709 --- 2.1.52 2007/03/07
1711 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1712 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1713 fd_set structure used as a bitmask for the FDs to be selected on.
1715 Using ACX_PTHREAD macro to check for POSIX threads.
1717 Fixed have-vsnprintf check.
1719 --- 2.1.50 2007/02/23
1721 Fixes for configure on BSD. Bug #900.
1723 Added snprintf/vsnprintf wrappers for systems that don't have
1724 limits (heavens forbid).
1726 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1727 created before all previous tasks were completed and removed from the
1728 task queue, the new task could be removed by a mistake.
1730 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1732 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1734 Fixed bug #832: Problem with MARC/charset in yaz-client.
1736 Fixed bug #668: save command line history for yaz-client.
1738 Fixed bug #830: pkg-config support.
1740 --- 2.1.48 2007/01/23
1742 Extended ZOOM result set options with two options that may be read by
1743 a client: resultSetStatus and presentStatus with values as specified for
1745 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1747 Fixed bug #827: Using SSL fails on Debian etch.
1749 Fixed bug #826: Weird looking chars for set of MARC records.
1751 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1752 that is treated as an ItemOrder with itemRequest being an XML document
1753 external. The value of "doc" is the content.
1755 Extended the GFS search facility. New member of bend_search_rr
1756 'estimated_hit_count' signals that hits is known to be an estmate
1757 (higher or lower than real hit count). New member 'partial_resultset'
1758 signals that the search was partial (hit count is lower or equal than
1759 real hit count). For Z39.50, the information is stored in resultSetStatus
1760 member of SearchResponse APDU. For SRU, the information is signalled
1761 via SRU diagnostic 59: "Result set created with valid partial results
1764 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1766 --- 2.1.46 2007/01/13
1768 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1770 Added ZOOM_connection_peek_event.
1772 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1773 the following new functions:
1774 ZOOM_event_nonblock, ZOOM_connection_process,
1775 ZOOM_connection_get_{socket,mask,timeout},
1776 ZOOM_connection_fire_event_{timeout,socket}.
1777 The existing blocking event handler, ZOOM_event, is a wrapper for the
1778 + blocking ZOOM_event_sys_{poll,select}.
1780 Implemented function ccl_xml_config which parses XML version of CCL
1781 configuration (bug #798).
1783 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1785 Added timings utility (yaz/timing.h)
1787 --- 2.1.44 2007/01/03
1789 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1792 Fixed bug #779: Rotation of apdu.log fails.
1794 Fixed for character set conversions:
1795 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1796 Honor G1 set in MARC-8 decoding.
1798 --- 2.1.42 2006/12/17
1800 Fixed bug #775: char conversion does not handle Alternative UTF-8
1803 Implemented function yaz_marc_read_line which parses MARC line format
1804 records. There is a wealth of formats out there. So far, this function
1805 reads line records produced by yaz_marc_write_line.
1807 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1808 more generic and easier to remember(!) options: -i format and -o format
1809 which specifies input format and output format respectively - where
1810 format is one of "marc", "marcxml", "line", "marcxchange".
1812 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1813 does not print anything except warnings for records.
1815 For yaz-marcdump, added support for MARC split into files (-s) with a given
1818 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1819 spec, at http://www.loc.gov/standards/sru/record-update/
1820 This has changed the binary layout of the following structs:
1821 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1822 bend_update_rr . Patch by Ko van der Sloot.
1824 Added GFS utility function bend_assoc_is_alive which returns 1 if
1825 association is still alive (client is connected); 0 otherwise (client
1826 closed connection). This allows busy servers to stop working for
1829 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1830 been a separate piece of software. This version of ziffy has been modified
1831 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1833 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1835 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1836 Client code may now interrogate options such as "init_opt_sort" to
1837 find out whether the server claims to support various options.
1839 --- 2.1.40 2006/11/27
1841 Added utilities yaz_{set,get}_esn to set/get element set name from
1844 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1845 of YAZ and has been so since YAZ 2.1.10.
1847 Implemented ZOOM_record_error which returns error information for
1848 record (surrogate diagnostic).
1850 --- 2.1.38 2006/10/31
1852 Updates for SRU Update by Ko van der Sloot:
1853 1. Changed name from "operation" to "action"
1854 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1855 versions in the code, marked as 'backward compatible'.
1856 3. Added diagnostics for SRU Update.
1858 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1860 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1862 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1864 For GFS, fixed problem with SRU diagnostic 'First record position out of
1865 range' being issued for 0 hits.
1867 zoomtst10 part of Windows Build.
1869 --- 2.1.36 2006/10/13
1871 Implemented yaz_filepath_comp which splits a path into file path
1872 components (required by Zebra 2.0.3+).
1874 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1875 BSD inspired license until now so this should not have any real impact on
1876 anybody. See http://www.opensource.org/licenses/bsd-license.php
1878 Fixed bug #687: Missing log lines.
1880 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1883 Fixed bug #689: SRU diagnostics to be added.
1885 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1886 whether a connection is idle (no more work do do).
1888 --- 2.1.34 2006/10/04
1890 Change type of optval from long to int for invocation of setsockopt with
1891 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1893 Added support for specifying the max log file size for the Generic
1894 Frontend Server. The size is given with option -r.
1896 --- 2.1.32 2006/09/21
1898 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1900 --- 2.1.30 2006/09/17
1902 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1905 Fixed bug in Generic Frontend Server that could cause a server to stop
1906 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1908 For the generic frontend server, the maximum record size is used as maximum
1909 size of incoming packages (SRU + Z39.50). The value until was previously
1910 only used in Z39.50 Init negotiation and, later, in a session controlled
1911 sizes of records returned. This is controlled using -k option. It can be
1912 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1914 --- 2.1.28 2006/09/04
1916 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1919 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1921 New option for yaz-marcdump -lpos=value which allows setting a portion
1922 of MARC header to a certain value.
1924 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1926 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1927 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1929 --- 2.1.26 2006/08/15
1931 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1934 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1936 --- 2.1.24 2006/08/08
1938 Fixed MARC ISO2709 encoding routines to deal with character set
1941 Minor changes to GFS logging. Database included in search request log
1944 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1945 cached/multiple records.
1947 Shared libraries are built by default on Unix+configure.
1949 Changed cql2pqf transformation to use a different evaluation order. The
1950 new order is: always, relation, structure, position, truncation, index
1951 and relationModifier. Old order was: always, relation, relationModifier,
1952 structure, index, position, truncation. Note that the the latter ones
1953 override former ones for identical attributes.. The new scheme means that
1954 it is possible to override any existing attribute with a relationModifier.
1955 And also that it is possible to override everything for the index rule
1956 (except the ones listed in relationModifier). No order is perfect but this
1957 one, we believe, covers more real cases.. The "always" should have been
1958 called "default", since the attributes there can be overridden with all
1961 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1962 compilation phase, but also for yaz-config --cflags output. This allows
1963 us to have public headers with Libxml2 stuff in them . It should also,
1964 eventually, make Libxml2 checks redundant in packages using YAZ, such
1967 --- 2.1.22 2006/06/15
1969 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1970 stored in uri, message and details.. Previously diagnostics were stored
1971 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1972 compatibility.. but he's probably the only one affected, so.
1974 Added support for CCL, compiled on the client side, in ZOOM-C. This
1975 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1976 input; the resulting query objects can be used for for searching with
1977 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1979 YAZ' configure searches for OpenSSL by default.
1981 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1982 SL_CTX_use_certificate_file. See
1983 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1984 for more info. Thanks to Ko van der Sloot.
1986 --- 2.1.20 2006/06/02
1988 Bug #600: SRU GET, POST support for yaz-client. Introduced
1989 command 'sru' which selects method SOAP/GET/POST.
1991 Allow missingValueAction to be specified for the sortspec string -
1992 function yaz_sort_spec. By default, the missing value action is null.
1993 Use ! to specify "abort". Use = followed by stringvalue to specify default
1996 Ensured that Present-handler (if defined) is called in GFS before any call to
1997 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1998 searchRetrieve requests.
2000 Documentation for YAZ is now based on the Docbook XML/XSLT using
2001 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2002 is no longer depending on jade/openjade or docbook-to-man scripts.
2003 PDF is no longer part of the distribution - but can optionally be
2004 made using DSSSL/jadetex or FOP.
2006 Added retrieval handling support in Generic Frontend Server to support
2007 conversion between MARC/XML as well as XSLTtransforms. See
2008 etc/yazgfs.xml for an example.
2010 Added Authentication support to Generic Frontend Server in SRU
2011 mode. Authentication using HTTP Basic is supported, as is the use
2012 of 'x-username' and 'x-password' parameters in the request itself.
2014 Added support for a new character set MARC8s identical to MARC8 except
2015 that it converts combined characters to single Unicode characters in the
2016 Latin-1 range (when possible).
2018 --- 2.1.18 2006/04/24
2020 ASN.1 compiler 0.4: generates brief Doxygen file header for
2021 generated .h/.c files.
2023 Utility yaz_iconv now supports conversion to MARC-8.
2025 New facilities for the MARC module. The reading - and writing of
2026 content are separate methods for the yaz_marc_t handle. The following
2027 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2028 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2029 format). Write functions have prefix yaz_marc_write_.. The existing
2030 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2031 available. Removed support for OAI-MARC and simplexml (not the
2032 simplexml from PHP5).
2034 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2035 to be returned for this connection.
2037 --- 2.1.16 2006/03/31
2039 Allow multiple languages and charsets to be specified with
2040 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2041 negcharset iso-8859-1,utf-8
2043 Translation of proximity nodes from CQL into PQF now works.
2045 Moved to automake 1.8, 1.9.
2047 Added function yaz_log_set_handler which allows a log handler to be
2048 installed. This handler will be called for all log messages. Output
2049 to file is also produced; but that can be disabled by passing NULL
2050 fname to yaz_log_init_file.
2052 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2054 For SRW (including GFS), accept application/soap+xml as content-type
2057 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2058 produces NO stylesheet reference even if a default stylesheet is specified
2061 --- 2.1.14 2006/03/14
2063 Updated Windows package to include yazd.dll + yazd.lib for the
2064 Development component.
2066 If the environment variable YAZ_LOG is set, then it is used as a
2067 string indicating the default level of logging to use if not
2068 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2069 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2070 used as before. So, for example, to omit warnings from YAZ logging,
2071 export YAZ_LOG=-warn
2073 cql_transform() now map structure and other attributes before indexes,
2074 so that index-specific structures and other attributes can override
2075 defaults. So now a combination of mapping specifications such as:
2077 index.dc.date = 1=date-modified 4=5
2078 does the right thing.
2080 cql_transform() now also respects the "always" mapping specification,
2081 which establishes an initial set of attributes to be used for all
2082 terms except where overridden by more specific attributes associated
2083 with the index, relation or modifier.
2085 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2086 which mode to use; one of "post", "get" or "soap" (SRW, default).
2088 Fixes for yaz_iconv routines: changed trie-based character set conversions
2089 to use only non-negative values for bit fields due to Sun's C compiler not
2090 supporting negative values.
2092 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2093 sequences where not read correctly. Fix by Rustam Usmanov.
2095 Updated win/makefile to use options, settings which makes things
2096 compile with VS C 2005.
2098 --- 2.1.12 2006/02/01
2100 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2102 In ZOOM socket code, use select instead of poll on MacOSX.
2104 ZOOM-C now support client-side compilation of CQL into RPN that is
2105 sent to the server, enabling CQL to be used against all Z39.50
2106 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2107 ZOOM_query object, and submit it using ZOOM_connection_search().
2108 The CQL-to-RPN translation uses a configuration file, the name of
2109 which must be specified in the Connection's "cqlfile" option.
2111 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2112 function, which takes as its start-term parameter a ZOOM_query object
2113 (which may have had either CQL or RPN set into it).
2116 --- 2.1.10 2005/11/29
2118 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2119 GFS to support this as well. Backend handler, bend_srw_update, does the
2120 update work. Code contributed by Ko van der Sloot.
2122 Allow retrieval of Search Result-1 information in ZOOM by the use of
2123 options that are attached to a result set. ZOOM documentation updated
2126 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2127 UTF-8 conversion. Patch by Raj Patel.
2129 Added option -m to GFS to control formatting of timestamps in log file.
2131 Added 'exit' as synonym for 'quit' in yaz-client
2133 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2134 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2135 for the new members. Patch by Ko van der Sloot.
2137 Added support for SRU POST. It is supported for content-type
2138 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2140 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2141 Instead make the library libyaz.la multi-threaded. Threading as a whole
2142 can still be disabled by configure option --disable-threads. Previosly,
2143 with older GLIBCs there were problems with MT libs under Apache. This
2144 has now been fixed a long time ago.
2146 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2149 CQL module modified to be case insensitive for relations/indexes/operations.
2151 Fixed bug in CQL transform code: incorrect value relationModifieder
2154 Added 'show all' command for yaz-client which retrieves all results
2157 Added new yaz-client, xmles, which takes a (private) OID and
2158 a document to be sent as an extended service request.
2160 Describe new yaz-client commands wait_response and set_auto_wait.
2162 Increase TCP/IP listener backlog from 3 (which I am guessing was
2163 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2164 that the socket will queue as many incoming connections as it's able
2165 to handle ongoing connections. In other words, it will never now
2166 refuse a connection that it would be able to handle merely because
2167 it's not got around to accepting() enough of the pending connections
2168 yet. This is the behaviour anyway under Linux, where the listen()
2169 argument is ignored; but not under BSD and on systems such as
2170 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2171 YAZ-based servers should now be uniform across operating systems in
2174 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2175 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2176 This allows yaz-marcdump to read large MARC batches (>2 GB).
2178 Modified all YAZ source files - except the source which is auto-generated
2179 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2182 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2183 corresponding to the existing *_setl() function. These allow option
2184 values containing arbitrary valuues.
2186 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2187 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2188 except that it returns an indicator of whether or not the sort
2189 criterion was accepted (0 for OK, -1 for invalid).
2191 --- 2.1.8 2005/06/07
2193 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2194 MARC output rather than returning "new" buffer.
2196 yaz-client warns about unknown init options.
2198 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2200 --- 2.1.6 2005/05/24
2202 Added support for SRW sort in Generic Frontend Server. Patch
2203 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2204 sortKeys - or NULL if none is provided.
2206 Fixed bug #307: It was impossible to specify indefinite/no timeout
2207 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2210 Added support for multiple languages and charsets to be specified in
2211 ZOOM. Each charset/language is separated by a blank. If negotiation is
2212 in effect in init-response, Option
2213 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2214 Code based on patch by Vasiliy Osadchuk.
2216 Fixed bug #306: infinite recursion that occurred when calling
2217 yaz_log_level_init as the first call (before other log level or
2220 Fixed bug in scan handling in front end server: if preferred-Position-In-
2221 Response was non-present, a NULL pointer referece was performed.
2223 --- 2.1.4 2005/04/26
2225 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2226 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2227 now defined for all those error codes. So instead of putting 109 in
2228 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2229 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2231 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2234 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2236 Program yaz-client now exits and produces an error message if multiple
2237 Z39.50 servers are specified on the command line (none or one allowed
2240 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2243 --- 2.1.2 2005/03/16
2245 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2247 Fixed bug #272: Preserve spacing for CCL terms.
2249 --- 2.1.0 2005/03/14
2251 Added support for virtual hosts and multiple backend servers for
2252 the YAZ frontend server. The configution is XML based and
2253 support specificition of CQL to RPN mappings and explain information.
2254 See section "Virtual Hosts" in the YAZ manual.
2256 Extended OPAC display utility. OPAC display utility renders
2257 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2258 to supplement yaz_marc_decode_wrbuf.
2260 Fixed a bug in MARC decoder that could caused it to crash for some
2261 invalid MARC records. More diagnostics and warnings where added in
2262 XML output (warnings, etc are stored in comments).
2264 --- 2.0.34 2005/02/08
2266 Fixes for UNIX domain sockets. Bug #261.
2268 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2270 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2271 Added yaz_marc_subfield_str which defines subfield lead string which is
2272 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2273 yaz_marc_endline_str which defines end of fields string used in
2274 YAZ_MARC_LINE format. Default string is newline.
2276 Experimental support for MarcXChange. This format can be produced
2277 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2278 http://www.bs.dk/standards/MarcXchange.xsd
2280 Added yaz-client commands scansize that sets maximum number of
2281 entries to be returned by scan.
2283 --- 2.0.32 2005/01/11
2285 Added support for SRW scan in yaz-client and Generic Frontend Server.
2287 * Added whereInList member to SRW Scan Term.
2289 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2291 Fixed NMEM system to return aligned blocks on the smallest boundaries
2292 that are suitably aligned for all possible types on the particular
2293 architecture YAZ is being built for.
2295 --- 2.0.30 2005/01/04
2297 Fixed numerious warnings that was issued with newer versions of GCC.
2299 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2300 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2303 Make YAZ Generic Frontend Server slightly faster.
2305 Enhance (and reduce) logging for Generic Frontend Server.
2307 Revert YAZ log system so that it flushes every write operation
2308 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2310 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2311 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2312 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2313 will effectively disable old definitions.
2315 --- 2.0.28 2004/11/09
2317 Added yaz_log_time_format which specifies log format using
2320 Added yaz_log_module_level which returns mask for a module. Value
2321 is non-zero mask a if module is enabled; zero if disabled.
2323 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2324 in include/yaz/cql.h.
2326 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2328 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2330 Fixed bug #172: RPM builds does not enable SSL.
2332 Doxyfile.in part of dist. Doxyfile generated by configure.
2334 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2335 are given and the corresponding component does not exist.
2337 Extend CCL documentation in YAZ reference. Describe r=r.
2339 --- 2.0.26 2004/10/01
2341 Fixed MARC->MARCXML conversion to properly deal with
2342 fields, subfields, indicators having non-ASCII characters.
2344 Fixed MARC->MARCXML conversion so that ASCII control characters
2345 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2348 Added YAZ GFS support for conversion from Z39.50 surrogate
2349 diagnostics to SRW surrogate diagnostics.
2351 Bug fix: YAZ GFS did not return schema in explainResponse.
2353 --- 2.0.25 2004/09/30
2355 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2356 now converts recordSchema to elementSetName as well as schema URI.
2358 Fixed bug in COMSTACK that prevented HTTP request packages from being
2361 --- 2.0.24 2004/09/29
2363 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2364 does not require white-space before and after the dash in a range, e.g.
2365 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2368 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2369 due to new GCC removing "redundant" code.
2371 Added yaz-client commands scanpos and scanstep that sets preferred
2372 position and step-size for scan.
2374 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2376 Added CCL utility ccl_qual_buf which parses one or more CCL
2377 spec lines in a buffer.
2379 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2380 of name and value - ignoring empty lines and comments.
2382 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2384 Added odr_get_element_path which returns current element path for an
2385 ODR handle. This utility is useful in error handling or user-defined
2388 Added ODR_PRINT utility odr_set_stream which is is a more generic
2389 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2390 to a write function and pointer to close function. The close function - if
2391 non-NULL - will be called during odr_destroy.
2393 Fixed bug in CCL parser where truncation char was not removed from
2394 right side when truncation=both was in effect.
2396 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2399 --- 2.0.23 2004/08/11
2401 Fix buffer overrun in CQL parser when dealing with proximity (%).
2403 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2404 to UTF-8/UCS conversion is now only based on codetables.xml.
2406 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2408 --- 2.0.22 2004/08/06
2410 Add support for more "commit changes" in ZOOM (uses Extended Services).
2412 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2415 Yet another small fix for configure of SSL.
2417 --- 2.0.21 2004/05/14
2419 Fix SSL libs for configure when --with-openssl=DIR is given.
2421 --- 2.0.20 2004/05/10
2423 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2425 SSL comstack now uses yaz.pem certificate file on server side
2426 by default. Certificate filename can be configured by calling
2427 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2429 Fix bug regarding multiple calls to ZOOM_connection_connect.
2431 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2433 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2434 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2436 ZOOM now allows inspection of X509 peer certificate for verification.
2437 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2439 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2440 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2441 as "modular" but it simplifies things.
2443 Added cs_get_peer_certificate to that returns peer X509 PEM.
2445 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2446 NULL if SSL is unavailable.
2448 Documentation about MARC decoding tools.
2450 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2452 --- 2.0.19 2004/03/30
2454 Rename CHANGELOG to NEWS to follow GNU style packing.
2456 Fix bug with missing initialization of member in init_diagnostics.
2457 This bug affects threaded version of GFS server.
2459 --- 2.0.18 2004/03/20
2461 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2464 Ensure zlib.dll is packed with Windows install.
2466 --- 2.0.17 2004/03/17
2468 Fix encoding of xsd:string to use text instead of CDATA.
2470 Fix endless loop in CQL parser with unbalanced ".
2472 Use a more compact way to store MARC-8 conversion tables.
2474 --- 2.0.16 2004/03/16 Debian only
2476 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2479 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2484 --- 2.0.15 2004/03/01
2486 Another fix for decoding of XML packed records.
2488 --- 2.0.14 2004/02/25
2490 Fixes for Chunked encoding. White space not ignored after length spec.
2492 Update NS and use default NS for SRW diagnostic elements.
2494 --- 2.0.13 2004/02/23
2496 Implement ZOOM_resultset_cache_reset which resets record cache.
2498 Implement ZOOM_resultset_sort which sorts a result set.
2500 Implement chunked HTTP transfer.
2502 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2504 --- 2.0.12 2004/02/16
2506 Added member 'schema' to bend_explain_rr structure so that backend
2507 can specify explain record identifier. Defaults to Zeerex 2.0.
2509 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2511 --- 2.0.11 2004/02/16
2513 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2516 Added init command for yaz-client which sends "extra" init request.
2518 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2519 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2521 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2523 Make ZOOM error code for "invalid query".
2525 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2527 --- 2.0.10 2004/02/05
2529 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2532 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2534 Added option -p <file> to make Generic Frontend Server to write PID file.
2536 Added option -D to put Generic Frontend Server in background on its own.
2538 Make ZOOM C recognize option "password". If unset, "pass" is used
2539 (for backwards compatibility).
2541 Fixed a bug in Generic Frontend Server that could make it crash if a
2542 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2545 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2546 Must be issued before open, in order to be in effect.
2548 --- 2.0.9-6 2004/01/12 Debian/Windows
2550 Make the SRU server more picky WRT unknown params, etc.
2552 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2554 New YAZ client command, options, that sets Z39.50 options.
2556 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2557 options from a string of tokens (one token for each option bit).
2559 Update SRW diagnostic code messages.
2561 --- 2.0.9-5 2004/01/07 Debian/Windows
2563 Handle user defined stylesheet for SRW/SRU.
2565 --- 2.0.9-4 2004/01/06 Debian/Windows
2567 Fix bug in decoding of Content-Length.
2569 --- 2.0.9-3 2004/01/06 Debian/Windows
2571 Fix a bug with decoding of XML packed records.
2573 --- 2.0.9-2 2004/01/05 Debian only
2575 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2577 Fix bug in SRW/SRU diagnostics decoding.
2579 --- 2.0.9 2004/01/05
2581 Fixed bug in Generic Frontend Server which could drop records exceeding
2582 preferred message size. Reported and fixed by Irina Dijour.
2584 Fixed calculation of package size for structured records in Generic
2585 Frontend Server. Reported and fixed by Irina Dijour.
2587 Fixed namespace for SRW/SRU diagnostics.
2589 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2591 --- 2.0.8 2003/12/22
2593 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2594 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2597 CQL changes to reflect recent changes to the specification:
2598 * Documentation talks about context sets instead of index sets.
2599 * Documentation talks about indexes instead of qualifiers.
2600 * The CQL-to-PQF transformer's configuration file now uses
2601 "index.set.name = <attributes>" instead of the old form
2602 "qualifier.set.name = <attributes>". (Both forms are still
2603 understood but the latter is deprecated.)
2604 * CQL terms with no explicit index specified are now interpreted as
2605 cql.serverChoice instead of srw.serverChoice (which of course
2606 behaves exactly the same.)
2608 --- 2.0.7 2003/12/16
2610 MARC conversion can now generate ISO2709 output in another
2611 character set. yaz-marcdump uses this facility if you invoke it
2614 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2615 functions from there can be used from C++.
2617 --- 2.0.6 2003/12/04
2619 Frontend server now transfers memory from decoded packages to stream
2622 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2623 references to show up.
2625 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2626 the ZOOM Abstract API. The older names for the same options are still
2627 also supported for the benefit of old applications.
2629 ZOOM-C supports "implementationId" and "implementationVersion" options
2630 to go along with "implementationName". These allow the user code to
2631 specify identification strings to be sent to servers.
2632 Add OID for the new ExtLite attribute set.
2634 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2635 as requested/supplid by Ere Maijala <ere@atp.fi>
2637 For generic frontend server, reverse the order of
2638 "toolkit-supplied / application-supplied" strings sent as implementationId,
2639 Name and Version. Also, remove the spaces around the slash. This brings
2640 the GFS in line with the behaviour of ZOOM-C on the client side.
2642 Add function ZOOM_scanset_display_term.
2644 yaz-client shows scan displayTerm if present.
2646 Utility yaz-iconv is now installed by default along with the man page
2649 Extend configure check for OpenSSL to use pkg-config where available (such
2652 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2653 server to specify uid/gid/mask for socket using the format
2654 unix:[user=uid,][group=gid,][umask=mask,]file=path
2655 If file= is omitted the existing format is assumed, e.g.
2657 in which case the mask is 0666 (rw for everybody).
2659 Major restructure of YAZ source. All source in libyaz is in src directory.
2660 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2661 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2663 Added man page for utility yaz-marcdump (used to be called marcdump).
2664 yaz-marcdump is installed by 'make install'.
2666 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2667 of incoming package failed.
2669 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2671 Change prototype of odr_perror: add const to message string.
2673 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2675 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2676 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2677 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2678 DNS lookup. There should not be any compatibility problems with this
2679 assuming that blocking=1 or 0 is used.
2681 Fix bad reference in UNIX comstack in function cs_addrstr.
2683 Fix for compilation on AIX.
2685 The generic front-end server (server/seshigh.c) now supports returning
2686 Init diagnostics to the client in User-information-field, in
2687 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2690 --- 2.0.4 2003/09/04
2692 Allow any CQL relation (not just all,any,exact,scr).
2694 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2695 that features the same UI.
2697 Implemented command update0 in YAZ client which is equivalent to
2698 update but uses old of Ext Update ASN.1.
2700 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2701 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2702 Previously no OID was used for this info.
2704 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2705 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2706 returns 'malformed search term' otherwise.
2708 SortResponse member resultCount now set to NULL in sort handler of
2711 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2714 Add three new utility functions for translating OIDs between various
2715 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2716 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2717 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2718 char *oid_to_dotstring(const int *oid, char *oidbuf);
2719 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2721 Reverted modifications for ES Update definition for z_IU0Update
2722 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2723 is back to YAZ 2.0.2.
2725 String value attributes for CCL parser.
2727 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2728 which their FirstSearch server returns in Init responses, sometimes
2729 carrying useful diagnostic information when Init fails. This has the
2730 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2731 "z39.50/oclcui.asn", where its definition is somewhat different from
2732 what OCLC document on their web-site, as required to interoperate with
2735 Support for anonymous authentication in yaz-client. Use the command
2738 * Fix the OID of the Index Data-local "admin" Extended Service from
2739 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2740 the 1000, which indicates a locally-defined OID, was a mistake.
2742 --- 2.0.3 2003/06/20
2744 Fix CCL directive @case handling so that it affects string match for
2745 both CCL keywords and qualifiers.
2747 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2748 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2749 Decoder has been updated with ASN.1 changes as listed in
2750 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2751 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2752 z_IUUpdate, remains unchanged.
2754 ZOOM_record_get may now return a record in a specific character set.
2755 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2756 "from" is the character set of record as returned by target. "to" is
2757 the character set to be returned. If omitted, "to" is UTF-8.
2759 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2761 New ODR utility, odr_getelement, which returns name of element for
2762 which encoding/decoding failed.
2764 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2765 in cases where a required element was omitted.
2767 Bug fix: some MARC8 sequences were not converted.
2769 New ZOOM option "step" which specifies number of records to be
2770 retrieved in one chunk. Used in conjunction with "start" and "count".
2772 SRW support for yaz-client. Use scheme http: to use it, e.g.
2775 yaz-client no longer does (un)intelligent character set conversions
2776 by default. Can be enabled with charset and marc_charset commands.
2778 xmalloc trace fix for 64-bit systems such as DEC alpha.
2780 Solaris 2.6 compile fix.
2782 New function, cql_strerror() translates SRW error codes, as returned
2783 by cql_transform_error(), into human-readable English strings. Used
2784 in yaz-client diagnostics when appropriate.
2786 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2787 converts it into a type-1 query which is sent to the server. This
2788 makes CQL available for use with all Z-servers, as opposed to the tiny
2789 minority that can handle CQL queries themselves.
2791 --- 2.0.2 2003/04/28
2793 New Debian package layout similar to the Redhat Package layout.
2795 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2796 and search result respectively.
2798 --- 2.0.1 2003/04/25
2800 Redhat package is now several packages: libyaz (runtime libraries),
2801 libyaz-devel (development and documentation, and yaz (utility programs).
2802 Package spec file by Morten Bogeskov.
2804 New member 'schema' in struct bend_fetch_rr which the name of requested
2805 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2806 handler MAY set this to reflect the schema of the returned record.
2808 New member 'display_term' in struct scan_entry. GFS now sets member entries
2809 and allocates scan entries to be filled by user scan handler. In previous
2810 version, entries member was allocated by the scan handler. That still works,
2811 but the GFS will ignore member display_term - assuming it was NOT set by
2812 the handler. The fact that the GFS now allocates the entries both allows
2813 for new members and makes a scan handler easier to write.
2815 Fix CQL lex buffer overflow.
2817 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2818 SRU default recordPacking is string.
2820 SRU protocol support for frontend server.
2822 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2824 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2826 Added scan for the ZOOM shell (zoomsh).
2830 * String Identifers for Schemas (Amendment 5).
2831 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2832 Old definition for schema
2833 Odr_oid *schema; /* OPT */
2838 Z_InternationalString *uri;
2839 #define Z_Schema_oid 1
2840 #define Z_Schema_uri 2
2843 * resultCount parameter to Sort Response (Amendment 1).
2844 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2846 Support for SRW 1.0 over HTTP. This is an optional feature and
2847 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2850 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2851 on the same port. SRW SearchRetrieveRequests are mapped
2852 to bend_init,bend_search,bend_fetch,bend_close.
2854 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2856 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2857 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2859 ZOOM connections are SRW based if schem http is used for hostname
2860 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2861 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2863 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2864 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2865 distance=n, order=true/false, relation=le, prox unit=word. If
2866 n is omitted, distance 1 is used.
2868 Fixed problem with C compiler include path in wrong order.
2870 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2871 on Solaris. Patch from Ko van der Sloot.
2873 New MARC decode API. All new functions operate on a yaz_marc_t
2874 handle. The most important new functions are: yaz_marc_create,
2875 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2876 decode and destroy respectively. Decoder can produce formats
2877 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2878 include/yaz/marcdisp.h.
2880 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2881 to UTF-8, UCS-32, wchar_t or Latin-1.
2883 * Prototypes for yaz_iconv_-functions moved to separate header
2884 include/yaz/yaz-iconv.h.
2886 Make a few private functions 'static' in unix.c. This prevents
2887 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2889 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2890 are set when Init Response is received.
2892 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2893 but returns diagnostic set as well.
2895 New function yaz_strerror which is a portable wrapper for
2896 strerror/strerror_r/GetLastMessage.
2898 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2899 is returned for MARC. If type is "oai", then OAI MARC is returned.
2901 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2904 --- 1.9.2 2002/11/26
2906 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2908 Fix bad race conditions on SIGTERM and terminate gracefully in
2911 Move retrieval (data1) module to Zebra since nobody seems to be
2914 Add GRS-1 render for ZOOM using same format as yaz-client.
2916 --- 1.9.1 2002/10/05
2918 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2920 Fix broken ESpec handling in data1 module.
2922 SGML reader parses comments and makes them part of the data1 tree.
2924 Added several type casts so that YAZ compiles as C++ code.
2926 ZOOM didn't handle PDU encoding failures properly.
2928 Added more Bib-1 diagnostics (approved extensions).
2930 GNU configure: better check for iconv.
2932 More portable use of accept, getpeername. Check for socklen_t. Use
2933 int/size_t if socklen_t is not defined.
2937 PQF parser rejects bad queries - including those with extra
2938 characters in them. PQF parser used to silently ignore that.
2939 Cleaner API for PQF added, which allows you to get detailed
2940 error information for bad queries (see yaz/pquery.h).
2942 Fixed bug in ZOOM_record_get for type "database".
2944 Implemented mini iconv library supporting conversions between
2945 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2947 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2949 --- 1.8.9 2002/08/20
2951 Fixed ZOOM C record cache so that preferredRecordSyntax and
2952 elementSetName is used to check for already fetched records.
2954 --- 1.8.8 2002/08/02
2956 Added three members in bend_initrequest structure to facilitate
2957 character set negotiation.
2959 Fixed a bug in frontend server that could cause indefinite
2960 loops under rare conditions.
2962 Revised character set utilities (charneg.h) so that encoding
2963 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2965 For PQF, directive @term <type> sets term type for Scan/Search.
2966 Here <type> is general, string, numeric, null. The term type
2967 is inherited - just like @attr.
2969 New call odr_set_charset that sets character set conversion for
2970 international-strings on a ODR stream. Prototype is:
2971 int odr_set_charset(ODR o, const char *to, const char *from);
2972 The InternationalString is still represented as C string in YAZ
2973 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2974 won't). On the protocol level, you can use any encoding.
2976 Support for UNIX sockets in ZOOM.
2978 Solaris recv sometimes returns errno == ENOENT. It is treated as
2979 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2981 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2982 both client and server. Code by Morten Bogeskov.
2984 --- 1.8.7 2002/05/22
2986 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2987 that they can be used directly from Visual Basic. You must recompile
2988 your windows APP if you're using ZOOM.
2990 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2991 Commands "lang" and "charset" sets language and character set respectively.
2992 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2993 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2995 Attributes from multiple CCL fields may be OR'ed rather than merged
2996 using directive "@field or". Fields are still merged by default -
2997 equivalent to "@field merge".
2999 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3002 Fixed bug in zget for parameter ExtendedServicesResponse.
3006 --- 1.8.6 2002/03/25
3008 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3010 Client displays USR.1:SearchResult-1 (hits per term).
3012 Additional Search Info for search in Generic Frontend Server.
3014 Fixed CCL parsing of "field=s".
3016 WIN32 installer - using the excellent NSIS software from nullsoft.
3018 Fixed CCL parsing of "field = - <number>".
3020 Added function yaz_marc_decode that decodes MARC for line mode
3021 display or XML (similar to that used by JZKit).
3023 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3024 Z39.50. But ISO/ILL was, however.
3026 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3027 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

3032 --- 1.8.5 2002/02/03
3034 New YAZ client features: Command completion and new commands:
3035 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3036 Code provided by Jacob Poulsen.
3038 New call oid_trav, that visits all registered OIDs via callback.
3040 Function ZOOM_record_get now returns const char pointer rather than
3041 void pointer. It saves a lot of type casts.
3043 For YAZ client, command "auth" now allows you to set authentication
3044 in IdPass style. It is enabled when three tokens are given - order
3045 is user, group and password.
3047 Fix memory leaks in MARC record handling for ZOOM.
3049 New option for YAZ client, -k <kilobytes> that sets
3050 maximum record size. Similar to -k option for generic frontend
3051 server and yaz-ztest.
3053 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3055 Prefix query parser reports "fail" when bad attribute set is given.
3057 Fix in MARC decoder. Proximity logging. Fix for attribute set
3058 in scan handler for server. Patches by Shigeru Ishida.
3060 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3063 Configure option --with-openssl=<dir> now works when a directory is
3064 specified. Patch provided by Morten Bogeskov.
3066 New option for YAZ client, -u <auth>, that sets authentication.
3068 ZOOM fix: error information was sometimes "missing", since error
3069 was cleared/reset too when it shouldn't.
3071 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3073 --- 1.8.4 2002/01/04
3075 Scan for ZOOM API. New object ZOOM_scanset. New functions
3076 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3077 ZOOM_scanset_destroy.
3079 New ZOOM function, ZOOM_connection_last_event, that returns type
3080 of last event (such as "receive data", "send data", "apdu received",
3083 New ZOOM option, schema, that specifies schema for retrieval.
3085 New CCL feature. Qualifiers can be aliases for one or more
3086 other qualifiers (if more than one is given, OR is used).
3088 ZOOM uses named result sets if target supports it.
3090 Two new YAZ client commands: . (dot, which sources a script of YAZ
3091 client commands), and ! (to execute shell command.). Implemented
3094 Working on Debian packages.
3096 --- 1.8.3 2001/11/19
3098 YAZ client enables named result sets only if target supports it.
3100 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3102 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3103 with key="host" to get same result.
3105 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3106 Function Z3950_resultset_record(s) returns references to records
3107 "owned" by resultset. To become owner use Z3950_record_clone.
3109 Function z_ext_record handles Extended Services. Thanks to
3112 --- 1.8.2 2001/11/12
3114 CCL Parser fix: ignore token comma when dealing with and-lists.
3116 Documentation updates for COMSTACK.
3118 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3119 Changed prototype Z3950_records. For some functions, int parameters
3120 were changed to size_t.
3122 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3125 New MARC decode/display function, marc_display_exl, which properly rejects
3126 non-ISO2709 records. YAZ client uses it.
3128 --- 1.8.1 2001/10/29
3130 Fix bug: local attribute set wasn't set correctly in PQF strings.
3134 * Old Z39.50 codecs no longer supported.
3136 Added ZOOM C binding. See http://zoom.z3950.org/
3138 Renamed states for COMSTACKs to avoid confusion with events.
3140 Implemented cs_look and proper cs_rcvconnect.
3142 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3144 Configure detects POSIX threads on OpenBSD.
3146 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3147 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3149 When error is returned from present handler, non-surrogate diagnostic
3150 is returned in present response (and fetch handler is no longer called).
3152 * Minor adjustments to pquery parser (PQF). Token characters may be
3153 escaped by using backslash (C-style).
3155 PQF parser allows string attribute values to be specified. For @attr,
3156 non-numeric characters after the equal-sign are treated as strings
3157 (e.g. @attr 9=title).
3159 CCL trunction character may be defined (@truncation in file)
3161 * function zget_ExtendedServicesRequest sets waitAction to
3162 waitIfPossible (was wait).
3164 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3167 CCL operator names may be set in field definition files (CCL_bibset).
3168 See ccl/bib1 for an example.
3170 Fixes in ASN.1 compiler for C++ compatibility.
3172 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3173 and "op_or" to avoid conflict with C++.
3175 Fixed problem with GNU readline detection on Redhat 7.0.
3177 Added step-size for Scan backend handler.
3179 Fixed bug that made the frontend server crash when no attribute
3180 set was specified for scan.
3182 Front-end server automatically switches to original working directory
3183 when installed as an NT service. Previously -w had to be specified to
3186 Added extended attributes for retrieval module (data1), so that data1
3187 records carry d1_readXML/SGML attributes. d1_read also supports
3188 null-data rules ( <tag/>)
3190 On UNIX when POSIX threads are available, a separate library libyazthread
3191 is created. Programmers should link with that library and the yaz library
3192 when using threads. The reason for the split was that some applications
3193 on Linux, such as Apache, doesn't work well when using shared objects that
3196 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3197 (or any frontend server) in SSL mode by specifying ssl: followed by
3198 address. Only tested on UNIX.
3200 Added feature for CCL module. Virtual structure s=al or s=ol generates
3201 and-list and or-list respectively instead of phrase search.
3205 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3206 log_mask_str. This was done to avoid name conflicts with other libraries
3207 (such as other PHP extensions).
3209 Added raw OID member for preferred record syntax (request_format_raw)
3210 and returned record syntax (output_format_raw) for backend fetch method.
3212 Config file yaz-config now accepts options so that it returns specific
3213 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3215 Shared library support for UNIX using GNU libtool.
3217 * Modified backend interface. Request/Response struct's replaced by
3218 one read/write C struct. For example bend_fetchrequest and
3219 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3220 Every handler - even search has to be registered in bend_init
3221 handler. This means that the YAZ library no longer refers to
3222 external functions and it makes it possible to make the whole
3223 thing a single DLL/SO.
3225 Added Segment handler for backend server.
3227 Added Zmbol/Zebra administrative functions to YAZ client.
3229 Threaded frontend server on UNIX (when POSIX Threads are available).
3230 Starting the server with option -T enables multi-threading.
3234 Added configure option --enable-comp/disable-comp to control use
3235 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3236 located in sub directory asn.
3238 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3239 in ${exec_prefix}/bin along with the other programs yaz-client and
3242 GNU automake used to maintain makefiles.
3244 Added several OID's.
3246 Changed retrieval module so that we can load records with no abstract
3247 syntax defined. Tagpaths in these records are fully composed of string
3250 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3254 On UNIX, the generated makefile now supports a proper 'make install'.
3255 The prefix can be set via GNU configure to set the install location
3256 (default is /usr/local).
3258 * YAZ programs client and ztest were renamed to yaz-client and
3259 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3260 locations, such as /usr/bin,/usr/local/bin,etc.
3262 * YAZ Header files were moved from include to include/yaz. YAZ Header
3263 files are referred to as include <yaz/log.h> rather than <log.h>.
3264 The YAZ include path (-I ..) is therefore the same as before. Programmers
3265 should update their #include statements or use -Ipath/include/yaz
3266 instead. The main motivation for doing this change is that YAZ header files
3267 can be installed in "standard" locations /usr/include,/usr/local/include
3268 without introducing conflicts, since ALL YAZ header files are stored
3269 in subdirectory yaz (under /usr/include for example).
3271 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3272 rather than project/workspace files. We switched because project files
3273 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3276 Changed name of logging function, logf, to yaz_log, to prevent name
3277 clash with some math-log functions. The YAZ header log.h defines logf
3278 to yaz_log (#define) so there should be no incompatibilities by this
3281 Added bend_start/bend_stop handlers for server. These handler are
3282 called on start/stop of server. For windows they are called whenever
3283 a service is started/stopped.
3285 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3286 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3287 in util/yc.tcl. The auto-generated C code structures are, in a few
3288 cases, incompatible with the old decoders. There are differences in the
3289 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3290 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3291 The preprocessor variable ASN_COMPILED is defined when the compiled
3292 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3293 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3294 wish to use the old encoders/decoders you can specify --disable-yc
3297 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3298 version so that it supports both new - and old version of DB Update
3300 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3301 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3302 change. The name parameter can be set to 0 in which no name is specified
3303 for the construction. The macros odr_implicit and odr_explicit sets name
3304 parameter to zero for the construction involved. New macros
3305 odr_implicit_tag and odr_explicit_tag are similar to the others,
3306 except that a name parameter is added. For programmers' that don't use
3307 ODR they probably only need to change the call to z_APDU and z_External.
3309 Added access control facility by interfacing the TCP wrapper library.
3310 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3311 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3312 name of the daemon and enables the access control as specified in
3313 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3315 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3316 den Dool <H.M.vdnDool@kub.nl>.
3318 Added reference ID parameter to most functions in server API - refer
3319 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3321 Changed name of ccl library to libccl.a (was ccl.a).
3323 Fixed bug in decoder for Explain (Category TargetInfo).
3325 Added support for GNU readline in client. Thanks to Jacob Poulsen
3326 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3328 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3329 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3330 IMPLEMENTATION! This change was made to the development version before
3331 the ZIG decided to retract the amendment. If any users MUST be
3332 compatible with the original Update definition, PLEASE CONTACT US, and
3333 we will include a separate definition corresponding to the old Update
3334 ES. Note that because of the change to the ASN.1 of the
3335 TaskPackageRecordStructure we cannot define a single structure that
3336 will support both versions.
3338 * Added const modifier to buffer parameter for some ODR/BER encoding
3339 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3340 completeWAIS, odr_dumpBER.
3342 Fixed bug in client.c which caused a crash when a scanResponse didn't
3343 contain positionOfTerm.
3345 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3346 * will cause an error in a client if a non-YAZ target sends both a
3347 * list of Scan entries and non-surrogate diagnostics.
3349 Retrieval module enhancements. Tag sets may be typed in the reference
3350 to it. From the .abs-file the "tagset" directive takes a third optional
3351 integer type for the tag set referenced. From a .tag-file the "include"
3352 directive takes a third optional type as well. The old "type" directive
3353 in the tag set itself is still recognized but acts as the default type
3356 Backend interface change. Individual Scan terms returned from bend_scan
3357 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3358 in include/backend.h.
3360 Retrieval module enhancements. Multiple tag sets and attribute sets may
3361 be specified in abstract syntax specs. Revised the error/warning for
3362 logging messages reported by the retrieval module when reading the
3365 Object Identifier system (oid_..) changed. The API is backwards
3366 compatible but the oid-routines now allocates new OID's when needed.
3367 Raw OID's may be specified in oid_getvalbyname.
3369 YAZ now uses GNU configure to generate Makefile(s).
3371 * Minor changes in some of the member names of DeleteResultSetRequest and
3372 DeleteResultSetResponse. See include/proto.h.
3374 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3375 and added member 'languages' in TargetInfo (which was missing).
3377 Changed the way attribute sets are handled in the retrieval
3378 module. These are now cached, just like the abstract syntaxes
3381 Changed YAZ so that it links with compiled ASN.1.
3383 Added Explain-schema definitions and mapping routines. The following
3384 Explain categories have been implemented: AttributeDetails,
3385 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3387 Fixed minor bug in Windows version of Server Library.
3389 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3391 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3393 Added EXTERNAL: UNIverse Resource Report (non-standard).
3395 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3396 ENUMERATED and SET OF.
3398 * Added 'const' to some of the char pointer arguments for the
3399 functions, data1_read_node, data1_getelementbytagname,
3400 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3403 Fixed bug in data1_insert_taggeddata - the last_child member of
3404 parent wasn't initialised.
3406 * Changed data1_read_record and data1_read_node so that the supplied
3407 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3408 doesn't refer to any parts of the "SGML"-buffer.
3410 Fixed bug in server library (Windows version of statserv_remove).
3412 * Changed code so that it compiles as C++. The type definition
3413 of Odr_fun which is a member of Odr_arm was changed. The result is,
3414 that an explicit typecast is needed for the fun pointer when
3415 using Odr_arm - as in:
3416 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3418 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3420 Implemented the new structured date and time definition as approved
3421 by the ZIG. Added schemaId element to the specificTag in Espec-1
3422 (also approved at the last ZIG). Thanks to RVDM.
3424 Added some Object identifiers (RVDM).
3426 Changed the Update Extended Service (RVDM).
3428 Added command "refid" to client which specifies referenceId for
3429 the following requests.
3431 Implemented extended service handling for server. See ztest.c
3432 for an example as well as backend.h. New handlers are registerd
3433 in the Init handler.
3435 * Changed interface for sort in server.
3437 Added new members to statserv_options_block. It allows a server
3438 to read options from another source than just the command line. Thanks
3439 to Charles Woodfield.
3441 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3442 renamed to zboolean. Some C++ compilers complained about the name.
3444 Minor changes to gils.abs. Added index 's' (sort) on title
3445 and date/time-last-modified.
3447 --- 1.4pl2 1998/1/30
3449 Fixed bug in server library regarding inetd mode (-i). This bug
3450 was introduced by release 1.4.
3452 --- 1.4pl1 1998/1/29
3454 Added sort facility in client and backend server interface.
3456 Fixed problem with dependencies in Makefile(s).
3458 Fixed bugs for encoders/decoders of extended services and
3461 Implemented sub-tree feature for schemas. Sub-trees are
3462 referenced in *.abs-files. See explain.abs for an example
3463 of the use of this feature.
3465 Modified bib1.att; local attributes for ANY didn't include
3466 ANY itself (only affects use of the retrieval module).
3468 Fixed bug in plain SGML reader in function data1_read_node:
3469 tags with prefix "var" was incorrectly interpreted as variants.
3471 Added feature "sub-schemas" to enable references to - and definitions
3472 of - group of elements.
3474 * Removed member parent from type data1_element (in data1.h).
3476 Implemented function odr_nullval() that returns the value of
3479 * Removed member num_children from data1_node (in data1.h).
3481 Made NT service interface part of the server library. The
3482 function statserv_main uses the NT service when required and
3483 calls the statserv_start / statserv_close routines.
3485 Routine zget_SearchRequest and zget_PresentRequest fills
3486 resultSetName/Id member with "default" instead of "Default".
3488 Fixed memory leak in server. Request queue member wasn't freed.
3490 Fixed nmem_exit so that memory is freed.
3494 Revised the CCL parser utility to be thread safe.
3496 Added function, oid_ent_to_oid, to replace the function
3497 oid_getoidbyent, which is not thread safe.
3499 * Added nmem_init and nmem_exit to initialize and release
3500 NMEM resources. Function nmem_init should be called once in the
3501 initial thread before NMEM/ODR is used. statserv.c and client.c
3502 have been changed accordingly. The change was necessary to make
3503 NMEM thread safe. The NMEM memory pool is shared amongst threads
3504 in a process. Unix-based applications will still work fine without
3507 Added NT Services interface for the the Z39.50 (statserv) Server.
3508 Refer to the ztest.c source on the usage.
3510 Windows 95/NT port using MSVC5.0. Project files are included in the
3513 * Defined new 'global' handle for the retrieval (data1) system. The
3514 new handled, data1_handle, describes the state of the data1 system.
3515 This handle is passed as first argument to virtually all
3516 data1 related routines. The functions data1_create and data1_destroy
3517 creates and destroys a data1 handle respectively.
3519 Added ODR encode stream member to all backend request structures
3520 init, search, scan etc. This stream should be used to allocate all
3521 memory used for the response when thread safe operation is needed.
3523 Changed the comstack utility, cs_addstr, to be thread safe. The
3524 returned hostname string returned by the function is now part the
3527 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3528 function. The cs_straddr takes a COMSTACK handle as argument, so this
3529 function must be used after cs_create and before bind/connect.
3530 This function is thread safe.
3532 Moved test server to 'ztest' directory - generic server code still
3533 in 'server' directory.
3535 Made prefix query (pquery.c) utility thread safe.
3537 Added new function modifier YAZ_EXPORT to 'export' public DLL
3538 functions when using windows (see include/yconfig.h).
3540 Added definitions to the OID database (util/oid.c) (RVDM).
3542 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3544 Added call to ccl_rpn_delete in client program.
3546 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3547 release of RPN structure.
3549 Added support for C++, headers uses extern "C" for public definitions.
3550 With input from RVDM.
3552 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3553 Thanks to Ronald van der Meer (RVDM).
3555 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3557 Added support for private extensions to the OID database
3558 (oid_setprivateoids()). Thanks to RVDM.
3560 Added optional, physical ANY (key replication)
3562 Fixed null-reference problem in GRS-1 output filter.
3564 Proximity operator added to Prefix Query Format (PQF).
3566 In test client command "base" accepts multiple databases.
3568 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3572 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3574 Smallish bug-fixes in the new encoders/decoders (explain).
3576 Bug fixed in DeleteRequest.
3578 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3580 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3582 Added SOIF syntax (using private OID for now) to retrieval module and client.
3584 Added Update extended service.
3586 Added SearchResult-1 additional info structure.
3588 Added optional CCL (ISO8777) interpreter as separate module. Available
3591 --- 1.2 1996/6/10 (1st anniversary release)
3593 Added Summary record syntax. Lightly tested.
3595 Added OPAC record syntax. Untested.
3597 Added ResourceReport service encoders/decoders. Untested.
3599 Fixed bug in z_Unit - wrong tagging on unitSystem.
3601 Fixed bug in the DiagRecs decoder.
3603 Added options for max PDU size and session timeout to frontend-server.
3605 Added documentation of query-language parsers and other supporting utilities.
3607 [frontend-server] Added Attribute set to the bend_scanrequest API.
3609 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3610 surrogate diagnostics were generated.
3612 [retrieval] Allow multiple local values for attribute.
3614 [retrieval] Allow multiple attributes per element in .abs files. index type.
3616 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3618 --- 1.1pl2 1996/4/10
3620 Minor changes, mostly specific to Zebra's requirements (retrieval)
3624 Repaired bug in frontend server when running multiple listening
3625 endpoints in dynamic mode.
3627 z_External() now won't break if a known, ASN.1 value comes encapsulated
3628 in an octet-string. The value will pass through unmodified in an Odr_oct.
3630 Added a bit of code to the demo client to decode & display
3631 ASN.1-structured records represented in the octet-aligned branch of
3632 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3634 Added z_ext_getentbyref() to the ASN module. Doc updated.
3636 * Completed the SCAN definition in the ASN module. This may break SCAN
3637 code based on older YAZ-versions at compile-time. The fix is easy -
3640 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3641 under the SCAN definition. Remember to initialize this, server-people.
3643 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3644 that this does not extend to ODR and ASN.
3646 Comstack allows insertion of established socket (primarily for
3647 inetd-operation of servers). Doc updated.
3649 Front-end server can now start from the inetd in TCP mode. Doc
3652 --- 1.0pl4 1996/1/24
3656 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3657 the rank and record number.
3659 Adjustments to the frontend server.
3661 Fixed diagnostic BER dumper. It ignored the file argument.
3665 Various changes to retrieval module.
3667 Changed the union discriminators of the protocol files from enums to
3668 ints paired with #defines.
3670 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3673 *Changed operator in the RPN structure to 'roperator', again to avoid a
3676 Fixed problems in Explain decoders/encoders.
3678 --- 1.0pl2 1995/12/6
3680 Memory bug in log module fixed.
3682 --- 1.0pl1 1995/12/5
3684 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3686 Bug in Explain DatabaseInfo module fixed.
3688 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3692 The shift to v1.0 signals that we now consider the *core* functionality
3693 of YAZ reasonably stable (the core being more or less equivalent to
3694 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3695 tested (Explain not at all - though that will happen soonish).
3697 Minor changes to code to support Windows port.
3699 Various minor changes after we're getting to use GRS-1 & co. more.
3701 Added Espec-1 format.
3703 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3704 of the protocol and it cannot be selected when encoding (maps into 'string'
3705 when decoding). Needed to talk to some servers.
3707 Demo client can request simple element set names.
3709 Added Diagnostic Format encoders/decoders.
3711 Added simple Close handling to frontend server (no hooks for resource
3712 reporting yet), and demonstration client.
3714 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3716 --- 1.0b3 1995/08/24
3718 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3719 handled incorrectly when records were requested in the searchResponse. This
3720 will only affect you if you use the frontend-server.
3722 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3723 Test-client will ask for and print GRS1. Ztest will return dummy records
3726 Added Explain encoders/decoders to the service-level API. Untested.
3728 Added Extended Services: Item Order encoders and decoders to the Service-
3729 level API. Untested. We could use a recent copy of the pertinent bits
3730 of the ILL protocol to add those bits.
3732 Added diagnostic format 1 encoders/decoders to the service-level API.
3735 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3736 odr_cons.c, which causes a more correct output.
3738 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3739 was always set to 0 when no records were requested in the searchRequest.
3741 * Added better external-handling. This shouldn't harm old code that
3742 *encodes* externals. It can break code that looks for a
3743 'single-ASN1-type' representation, since those types that are known
3744 are now decoded immediately. Look at the SUTRS sample code in
3745 seshigh.c and client.c. Documentation updated.
3747 Handling of structured records in bend_fetchresponse. Length -1 marks
3748 structured record, type is deduced from format field.
3750 --- 1.0b2 1995/06/27
3751 Fairly quick maintenance release to add SUTRS support.
3753 Fixed handling of SUTRS records in the demonstration client.
3755 * Added format field to the bend_fetchrequest and bend_fetchresponce
3756 structures of the backend API (frontend server). When the record is
3757 returned, the value of the format field is mapped to an OID. The
3758 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3759 of the record. The special value VAL_NONE in the bend_request means
3760 that no specific format was requested by the client. Documentation
3761 updated accordingly. Test server (ztest) will return a fixed dummy
3762 SUTRS record if your client requests SUTRS.
3764 Documentation updated accordingly.
3766 You can now set external libraries and RANLIB support in the top-level
3770 First public release.
