3 yaz-ztest: -V shows version (like yaz-client -V)
5 New iconv encoding: danmarc YAZ-692
7 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
9 daemon: only wait for immediate child rather than all children. YAZ-704
11 yaz-client: fix setting of SRU record schema. If scheme was unset, it
12 could lead to invalid memory reference.
16 yaz-ztest returns schema for MARCXML test records. SRU require that
17 recordSchema for records.
19 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
20 instead of non-surrogate diagnostic. This is a per-record failure.
22 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
23 may refer to multiple listeners now. Attribute listenref is a comma separated
26 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
27 option is given for GFS, the dirname of filename (for -f) is used
28 as prefix for options such as cql2rpn, ccl2rpn, etc.
30 Content-Type charset fixes YAZ-701 . Do not inspect charset in
31 Content-Type header for SOAP when decoding SRU. The payload (XML)
32 itself tells what encoding it is. In response, never supply encoding
33 in Content-Type. The response payload (XML) tells what it is (with no
34 encoding in XML it's UTF-8).
36 HTTP decoding: allow blanks in URL paths YAZ-700
40 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
41 and facets. Ensure recordData and recordSchema are always present in
42 record element, because they are required.
44 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
47 Simplify in a lot of places using odr_strdupn.
49 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
53 Increase various buffers in GFS's statserv_options_block
54 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
55 This change makes many type-casts redundant, and, thus simplifies code.
57 Remove last bits of WAIS support.
59 Remove member 'size' from Odr_oct.
61 Slim down the public part of 'struct odr'. Most elements are not part
62 of struct Odr_private.
64 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
65 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
66 In particular facets are supported in both client - and server side.
67 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
68 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
69 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
70 both request/response). This is what a search handler in the GFS
71 will see (regardless of whether operating in SRU mode or Z39.50).
73 Changes to the srw.h (SRU/Solr) definitions include:
74 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
75 (char*), which replace union query and query_type (int). This is because
76 SRU 2.0 supports a queryType parameter. This also means that, to carry
77 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
78 x-pquery=PQFstring (extention parameter). The extension parameter
80 - New element, packing, that has information about SRU
81 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
83 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
85 New element, packing, in Z_SRW_explainRequest.
87 New elements in Z_SRW_scanRequest, queryType and scanClause.
88 These replace query_type and scanClase untion. This is similar to what
93 GFS: log when closing down - at least SIGTERM YAZ-684
94 Also change formatting WRT PID logging a bit.
96 Improve display of MARC records with multi-byte subfield IDs YAZ-695
97 In some rare cases subfield identifiers are multi-byte characters.
98 This will try to deterime length of those and split accordingly.
99 This affects display in line mode as MARCXML/MarcXchange. The encoding
100 of ISO2709 is the same.
102 Change inp argument to const for yaz_read_UTF8_char.
104 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
106 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
108 Better check of marc leader info YAZ-691
109 Problem is that some systems generate MARCXML/MarcXchange with
110 funny headers. These will not work if encoded as ISO2709.
111 Some tests produce new output, due to updated warning messages
113 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
115 yaz-client: display MAB records YAZ-689.
116 Thanks for Heiko Jansen for this patch.
118 New utility z_get_HTTP_Response_server which allows both HTTP server name
119 and HTTP server URL to be given in response.
121 Debian: do not depend on obs tcl8.3.
123 Debian: do not depend on obs libicu36-dev.
125 --- 4.2.68 2013/09/23
127 GFS: pass additionalSearchInfo to search memeber search_input if
128 given. Otherwise pass otherInfo. Request for facets and other search
129 related things will be passed there in future versions of YAZ.
131 New ZOOM setting, authenticationMode, which allows authentication
132 paramters to be encoded in the URL rather than via HTTP Basic auth.
135 rpn2solr: fix nested AND/OR handling. YAZ-685
137 Add comparison routines for some Z-types, such as NamePlusRecord,
138 RPNQuery, Query, RecordComposition and OtherInformation.
140 --- 4.2.67 2013/09/19
142 Don't decode MAB as MARC. Just like we don't attempt to decode
143 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
145 CCL: allow quoted terms for date ranges. YAZ-681
147 Introduce ccl_parser_qual_search. This function makes old function
148 ccl_qual_search, from YAZ 2, available again.
150 Add yaz_facet_list_to_wrbuf. YAZ-683
152 --- 4.2.66 2013/09/11
154 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
155 schema was given for search. YAZ-675
157 Add Solr date range searches. YAZ-621
159 --- 4.2.65 2013/08/22
161 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
163 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
165 ISO2709/MARC parse most octet aligned records; not just those that
166 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
167 MARC parse more records instead of just dumping as is. YAZ-670
169 ZOOM: proper caching for variations of record schema. YAZ-671
171 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
173 --- 4.2.63 2013/07/17
177 --- 4.2.62 2013/07/11
179 New utility z_get_HTTP_Response_details - an extended version of
182 New utility yaz_url_get_error which returns error message of last
183 failed yaz_url_exec call.
185 yaz-url and url functions: allow max HTTP redirects to be controlled.
187 New functions yaz_file_glob2, yaz_xml_include_glob.
188 These functions takes a flags parameter, which, for now only controls
189 whether to fail inclusion of a non-existing file (without glob
190 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
192 --- 4.2.61 2013/06/20
194 For MARC XML parsing, allow record without leader. A fake/default leader
195 is inserted and a warning is tagged with the record.
197 ICU: fix leak in in icu_iter_get_org_info.
199 --- 4.2.60 2013/06/14
201 ICU: fix bug in icu_iter_get_org_info (un-init variable).
203 --- 4.2.59 2013/06/11
205 Implement z_HTTP_header_remove.
207 --- 4.2.58 2013/06/11
209 ICU: Disallow 0 ptrs for some ICU string utilities.
211 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
212 returns original tokens (before normalization).
214 CCL: avoid z39.58/regex truncation when not needed. Apply only the
215 conversion of those masks, when absolutely necessary.
217 CCL: configurable masking character - @mask. Default masking character
220 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
221 full response anyway, so a Transfer-Encoding header will obstruct the
224 --- 4.2.57 2013/05/15
226 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
227 picking a socket. Problem is that some systems has IPV6 support, but
228 we can't create sockets for them, so we pick AF_UNSPEC first.
230 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
231 use content_len to determine resulting Content-Length in HTTP response
232 and NOT Content-Length supplied in headers by user.
234 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
235 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
237 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
240 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
241 with big endian and unsigned char (by default).
243 --- 4.2.56 2013/04/26
245 Fix yaz-client connect (crash in 4.2.55).
247 --- 4.2.55 2013/04/26
249 Fix proxy/host problem for ZOOM that could occur if unix sockets
252 New Debian package libyaz4-dbg.
254 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
255 differently in tcpip_close.
257 --- 4.2.54 2013/04/17
259 Windows installer of YAZ includes YAZ4J as a component.
261 CQL: allow "extra terms" again, by default. Thus, the CQL parser
262 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
263 and earlier. CQL parser may operate in strict mode where queries
264 not conforming to the standard BNF are rejected (syntax error).
265 Whether the CQL parser operates in strict mode is controlled with
266 cql_parser_strict . Strict mode enabled with option -S for utilities
267 cql2pqf and cql2xcql .
269 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
271 --- 4.2.53 2013/04/10
273 New charset, MARC-8c, which is like MARC-8 but allows control characters
274 0x01 through 0x1F, except ESC to be passed through verbatim.
276 Fix a problem with duplicate sub field character in MARC output. Problem
277 happened only when output was MARC-8 encoded.
279 --- 4.2.52 2013/04/03
281 yaz-ztest: Use hash for fake hit count. Before, random number was used.
282 This is problematic for unit tests using yaz-ztest. This patch also makes
283 a hash for CQL queries. For RPN, any term with a leading digit will be
284 treated as pseudu hit count (to force any particular hit count by a client).
286 yaz-ztest: return unique MARC dummy records. Beyond record offset
287 24, the author surname is patched with offset to make all records
290 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
291 on system wide default (/proc/sys/net/ipv6/bindv6only).
292 @4 binds to IPV4 only. @6 binds to IPV6 only.
294 Update CQL API documentation a bit
296 CQL: don't accept extra terms for queries. Makes the CQL parser
297 stricly conformant to the standard.
299 --- 4.2.51 2013/02/12
301 GFS: scan handler gets extra_args from request and may return extra
302 response data . That's for SRU only.
304 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
306 --- 4.2.50 2013/01/30
308 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
310 OPACXML: sync spelling of availabilityDate in XML to that of Schema
311 opaxxml.xsd. The schema had the correct spelling of this member always.
312 The ASN.1 was mis-spelled and still is (API change) - we are
313 not changing this. However, the OPAC to XML conversion had yet
316 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
319 New function, z_ext_record_oid_nmem, which is similar to
320 z_ext_record_oid but takes NMEM rather than ODR
322 --- 4.2.49 2013/01/18
324 ICU: New conversion element 'join' which joins tokens into one
325 with a custom character given by rule attribute.
327 --- 4.2.48 2013/01/10
329 New GFS search member: present_number. This is a hint to the
330 search handler how many records are going to be fetched immediately
331 following search. There's no guarantee that it's going to be the case,
332 since it depends on hit count (for Z39.50 piggyback) and whether errors
335 Make a few functions static (private). The functions getbyte_stream,
336 ungetbyte_stream and yaz_gets are now private. They were never declared
339 yaz-marcdump: exit(5) for serious decoding errors
341 ISO2709 decoding: be more picky WRT header
343 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
344 was only used as to indicate that next-result-set-position should be
346 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
347 Based on patch from Ashley Sanders.
349 Make some functions static/private in PQF parsing. Those functions were
350 never declared in a public header and so should not be in use by
351 applications based on YAZ.
353 --- 4.2.47 2012/11/23
355 ZOOM: special options to control APDU logging.
356 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
357 logging of APDUs until "saveAPDU" option is set again. If logging is
358 already enabled the effect is that current APDU buffer is cleared.
359 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
360 logging (default behavior on new connection).
361 The APDUs sent/received can be obtained by using
362 Using ZOOM_connection_option_get(c, "APDU") or
363 ZOOM_connection_option_getl(c, "APDU", &l).
365 GFS: relay implementation_version from backend
366 From 3.0.40 and later, implementation_version from backend was
367 not used in init response at all.
369 --- 4.2.46 2012/11/15
371 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
372 mode at all. Probably never did.
374 Make a new version of ztest.pem that, at least, is not expired.
376 --- 4.2.45 2012/11/13
378 Fix description of CCL directive 'case'.
380 More tight checking of form arguments (yaz_uri_to_array). Makes
381 YAZ better at rejecting big and/or bad POSTs.
383 SRU decoding does not report more than up to 10 invalid arguments.
385 rpn2cql: less quotes in generated terms. Semantics unchanged, but
386 it's prettier this way.
388 --- 4.2.44 2012/10/25
390 New utility yaz_decode_init_diag. Defined in proto.h.
392 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
393 given for unix local socket.
394 The COMSTACK string for doing so is:
397 unix:/myfile:tcp:localhost:9999/mybase
398 unix:/myfile:localhost:9999/mybase
399 unix:/myfile:http://fakehost/mybase
401 debian: Use dpkg-buildflags in build process.
403 --- 4.2.43 2012/10/19
405 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
406 global's SRU service uses a recordPosition scheme starting from zero.
407 First record's position should be one
408 according to the standard.
410 --- 4.2.42 2012/10/18
412 Allow more namespaces for SRU. This is to allow, for example, an
413 incorrect namespace returned from server
414 http://services.igi-global.com/sru .
416 Minor fixes for compilation on Windows.
418 --- 4.2.41 2012/10/11
420 daemon: log total number of bad signals from child on stop so that it
421 is more easy to spot problems with child worker processes.
423 retrieval: empty backend name attribute omits element set
424 from being used in retrieval.
426 --- 4.2.40 2012/10/04
428 Implement Solr sort strategy "solr", similar to sru11 sorting.
429 This will implement the correct parameters on Solr requst to do
432 --- 4.2.39 2012/09/28
434 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
437 MARC: Extra/missing indicator handled for MARCXML.
438 The indicator length is given in header and is the same for the
439 whole record. If attributes ind1, ind2 are missing, then content
440 character defaults to blank. Extra indicator attributes (beyond)
441 indicator length are treated as an error.
443 Reformat: delete trailing whitespace
445 --- 4.2.38 2012/09/17
447 MARC: fix non-ASCII characters for leader. This is to ensure we can
448 generate XML in UTF-8.
450 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
451 in one node with structure word.
453 --- 4.2.37 2012/09/04
455 yaz-json-parse: JSON output may be pretty printed by using option
458 Increase default value of max message for Z39.50 Init for GFS, ZOOM
459 and yaz-client. Old value was 1 MB. New value is 64 MB.
461 --- 4.2.36 2012/08/22
463 yaz-client: don't display bogus records from SRU servers. Some SRU servers
464 return more records than given by *maximumRecords*. Skipping those in
467 record_render: simplify buffer return handling and fix at least one bad
468 memory reference, that broke the test_embed_record sometimes.
470 Allow http://user:pass@host notation for yaz_url_exec.
472 zoomsh: allow shell command to be executed. Via the system(3) call.
474 yaz_poll: Allow num_fds == 0
476 yaz-client: fix bad encoding of "itemorder item". The itemorder
477 item <no> - command forgot to use length of encoded Item Request
478 package. Error present since YAZ 3.
480 yaz-ztest: fix bad usage of session handle. Bug was introduced when
481 result sets were saved (271a9c83).
483 SRU recordPacking: guess record packing in response rather than looking
484 at the recordPacking element which, OF COURSE, changed semantics in SRU
487 Decode SRU 2.0 responses. The official namespace for responses, according
488 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
489 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
490 nature.com's server, however, usee namespace
491 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
492 we are now using a glob-expr to match up the namespace. ZOOM C and
493 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
494 I can not find a single real example showing the "real" namespace in
495 the documentation from OASIS. The namespace for requests is different
496 from responses, but this is not added to YAZ yet, when we don't encode
499 --- 4.2.35 2012/06/26
501 zoom/record_render: add support for Base64 decoding fo MARC records
502 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
503 which will decode base64 + ISO2709 marc-8 encoded material from text node
506 --- 4.2.34 2012/06/07
508 Add missing definitions ZOOM_resultset_get_facet_field_by_index
509 and ZOOM_resultset_facets_names.
511 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
514 Change APDU dump printing to avoid long leading blanks. For levels 16
515 or larger the level is shown and the indentation is truncated but
516 recursed with modula 8. This makes it still reasonable easy to read
517 - even for nested BER dumps.
519 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
520 return 0 (incomplete package) in case where the BER package was
521 considered too nested (return value of -2).
523 dumpber: lines of level 15 are not indented further. Two spaces per
524 indentation; indentation 15 or more is indented to a fixed indentation
525 and augmented with a level=<no> indication.
527 zoomsh: increase max size of command+args
529 GFS: No limit in RPN buf size in CQL to RPN conversion.
531 --- 4.2.33 2012/05/09
533 New function for daemon utility, yaz_daemon_stop .
535 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
537 --- 4.2.32 2012/04/25
539 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
540 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
542 --- 4.2.31 2012/04/23
544 YAZ daemon utility relays SIGUSR1 to child process.
546 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
547 would result in en empty database list - which in turn would result in
548 encoding failure for search.
550 Fix reading beyond string in yaz_sort_spec.
552 --- 4.2.30 2012/04/11
554 Add two new SRU diagnostics:
555 236: Access to specified database denied
556 1015: Init/AC: Maximum number of simultaneous sessions for Userid
558 Document the very useful ZOOM-C option "apdulog".
560 CQL to RPN: term may be passed through verbatim. This is enabled with
561 truncation.cql . The assumption being that the term is already CQL.
563 --- 4.2.29 2012/03/20
565 record_conv: leader spec may be given for marc element.
566 The leader spec is given as attribute leaderspec for element marc.
567 For example to convert a MARC21 record from MARC-8 to UTF-8:
568 <marc inputformat="marc" outputformat="marc"
569 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
571 record_conv: allow user-XSLT params. For example:
572 <xslt stylesheet="MARC21slim2DC.xsl">
573 <param name="myparameter" value="myvalue"/>
574 <param name="otherparameter" value="othervalue"/>
577 record_conv: fix error handling for missing marc charsets.
579 CQL: fix extra terms in wrong order.
581 --- 4.2.28 2012/03/06
583 record_conv: modify new API for conversion types. The conversion types
584 may be passed in new functions yaz_record_conv_configure_t and
585 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
587 Avoid mixed statement/variable declare; fixes compilation with Visual
590 --- 4.2.27 2012/02/28
592 Add non-standard SRU diagnostic: 235: "Database does not exist".
593 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
594 Update SRU to Bib-1 diagnostic maps accordingly.
596 CCL: add two new diagnostics for unsupported masking. The new
597 diagnostics are: "Embedded truncation not supported" and
598 "Single charcacter mask not supported".
600 --- 4.2.26 2012/02/23
602 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
604 --- 4.2.25 2012/01/11
606 Build YAZ for Ubuntu Oneiric.
608 CCL: allow parantheses for proximity operands. For example CCL query
609 (a) % (b) is now allowed.
611 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
612 marked dead, rather then being destroyed. If not, the session memory is
613 being free'd before the search/scan handler is finished. Also destroy
614 'request' memory in request_release rather than in various places,
615 which resulted in leaks from time to time.
617 --- 4.2.24 2011/12/21
619 cql_sortby_to_sortkeys: honor sort prefix.
621 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
622 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
623 The rpn2cql family of functions now always returns quoted CQL terms.
625 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
627 --- 4.2.23 2011/12/15
629 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
630 sequence is treated as one. For example, &&a=b&&&c& is identical to
633 --- 4.2.22 2011/12/05
635 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
636 APDUs for a connection to a WRBUF.
638 --- 4.2.21 2011/11/23
640 Fix cql_sortby_to_sortkeys. Completely broken before.
642 Make CCL's @truncation work again.
644 --- 4.2.20 2011/11/09
646 New ZOOM connection setting: tproxy. It's like proxy, but does not
647 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
648 to set resolved address + port for a connection outside ZOOM itself.
650 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
652 --- 4.2.19 2011/11/07
654 Fix uninitialized variable in Solr spell support (could cause SEGV
655 for SRU response decoding).
657 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
658 back-end's addinfo through into the ZOOM response addinfo.
660 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
661 they are separated by a colon and a space rather than simply
664 --- 4.2.18 2011/10/28
666 Add support for Solr spell-checking/suggestions through ZOOM.
667 If a Solr target has been configured correctly for spelling-checking
668 and suggestions, these will now be returned on the ResultSet option
669 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
671 --- 4.2.17 2011/09/28
673 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
674 with a flag whether to substitute escape sequences or not.
676 --- 4.2.16 2011/09/22
678 Fix nmem_strsplit_escape to substitute escape char properly.
680 New option for zoomsh -e , which makes it abort on first error and
681 return process exit code to indicate success/failure.
683 YAZ options utility supports special option -- which makes all it treat
684 all following arguments as non-options.
686 --- 4.2.15 2011/09/16
688 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
689 searched if absolute filename is given.
691 Fix conv_xslt() error-reporting when stylesheet is not found.
692 (The value of fullpath is meaningless in this situation.)
694 --- 4.2.14 2011/09/07
696 Fix problem in CQL sort node creation: un-initialized memory.
698 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
699 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
700 CQL sortby depending on whether Type-1 or CQL is actually sent to the
703 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
704 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
706 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
707 will make it possible to use both single-character mask (#) and wildcard (?)
708 in CCL . Throw diagnostic for left truncation because that is not supported
711 --- 4.2.13 2011/09/01
713 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
714 cases using escapes (\-sequences) and masking.
716 PQF parse fix: A trailing backslash followed by end-of-string (\0)
717 would result in a read one byte beyond string.
719 rpn2ccl may use Z39.50 masking for terms (t=z).
721 ICU check fix. Don't include library -lCrun on Solaris, unless present.
723 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
724 not --cppflags (which seeems like an error in icu-config).
726 --- 4.2.12 2011/08/27 RPM package only
728 cql2ccl: fix conversion of terms: operator characters were not
731 --- 4.2.11 2011/08/25 RPM package only
733 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
734 CCL parser will map both # and ? to their regular expression
735 quivalents (. and .*).
737 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
738 of reserved CQL characters.
740 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
741 is, so that they are passed through.
743 --- 4.2.10 2011/08/24
745 ZOOM SRU mode: more aggressive re-connect.
747 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
748 made available as a utility function, declared in <yaz/logrpn.h>
750 rpn2cql_structure() supports proximity nodes (except that the Type-1
751 proximity node's "exclusion" binary is ignored, as there is no way to
752 express that in CQL). Fixes bug #4564.
756 Fix SEGV that could occur if set command of zoomsh was given without
757 value (2nd argument).
759 Fix SEGV that could occur if unsupported transport was given for
760 COMSTACK - say https (when SSL was unavailable).
762 Build yaz-url on Windows too.
766 New utility to get web content. Header is url.h. A command line tool
767 yaz-url is part of the distribution and packages.
769 Fixes for SSL COMSTACK (when gnutls is in use).
771 New functions yaz_base64{encode,decode}. Header is base64.h.
775 ZOOM C includes HTTP response buffer as additional info if it fails
776 to decode the SRU response.
778 Make wrbuf_json_puts available.
782 zoom: throw diagnostic for invalid value for option "sru". Before a
783 bad SRU request was sent.
785 Adding new utility wrbuf_vp_puts.
787 Add cclxmlconfig.obj to win/makefile. It was missing completely.
791 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
792 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
793 redirect was used at the same time.
795 MARC line mode decoding: be less picky about length given - first
796 5 digits of header that is.
798 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
800 Changes to decoding of SRU records: a record with recordPacking=xml is
801 modified with a new root element <yaz_record> if the recordData contains
802 multiple children elements. This is to make the record XML parseable
805 RPN to Solr conversion: encode special characters.
807 Generic Frontend Server: fix uinitialized member, stepSize.
811 Fix a bug in SRU decoding of records.. The database records stored
812 had un-initialized memory, but it would only be seen with yaz_record_render
813 and type_spec="ext" .
815 Fix a bug in ccl_qual_dup introduced in 4.2.3.
819 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
823 Add new utilities to convert from CQL to CCL . These utilities have
824 prefix cql_to_ccl defined in cql.h.
826 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
827 lead to memory heap corruptions when ICU utilities were in use.
831 Make compilation work without Libxml2.
833 yaz-client: remove redundant blanks in display of searchResult-1 term
838 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
839 resulting CQL node (tree) in a new node CQL_NODE_SORT.
841 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
842 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
843 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
844 Note that the CQL sortby spec is only converted when the GFS is already
845 converting from CQL to RPN (cql2rpn element).
847 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
848 specify whether to collapse delimitors or not. The existing nmem_strsplit
849 do collapse (collapse parameter = 1).
851 Windows installer: For NSIS, set InstallDir depending on x86/x64.
853 Rename internal func yaz_use_attribute_create. While non-static, this
854 function is not declared in a public header.
858 Add -lCrun when linking with ICU on Solaris.
860 More quicks character set conversions for OPAC records.
864 fix problem with record_render: records were converted (character set
865 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
869 SRU: add methods for handling DADS SRU-proxy facets.
871 Separate OPAC record character set for ZOOM_record. yaz_record_render
872 allows a character set given as charset=from/opacfrom,to where 'from' is
873 the character set of a bibliographic record, 'opacfrom' is character set
874 of OPAC record and 'to' is the target character set.
878 yaz-client: show may XML format records. Command show followed by 'format'
879 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
882 src/stemmer.c: Avoid using unnamed union. It is not supported by some
885 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
888 Update yaz.spec to operate on both SLES11 / Centos 5.5.
890 RPM: Release includes 'indexdata' name. Use indexdata in release name so
891 this package can be distinguished from other vendors.
893 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
894 as determined by configure
896 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
898 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
899 returns no error and no record, the present request is considered
900 partial (only a subset of the records could be returned by backend), and
901 so it is appropriate to set Present Status to partial-4.
905 Move yaz-config man pages to section 1.
907 More documentation about Solr.
909 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
910 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
911 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
912 peers on some Linux systems. However, in general that does not work
913 so YAZ can not rely on that to work. Debian changed behavior in this
914 respect from Debian lenny to Debian squeeze (still testing as of Oct
916 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
918 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
922 Fix yaz-config output: echo_source not set correctly by configure.
926 Solr Web Service support for yaz-client and ZOOM.
928 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
930 --- 4.0.12 2010/08/17
932 Z39.50 facet support. Facet specifications are passed for search in
933 other-information with ASN.1 as defined in facet.asn and OID
934 .10.1000.81.5 . Facets are expressed as an Attribute list as known
935 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
936 3 is limit (number of entries to get in response). yaz-ztest returns
937 dummy facets if a client asks for them.
939 --- 4.0.11 2010/07/09
941 CCL fixes: bug 2895 and bug 3539.
943 GR1-display: add comma in display - was removed by mistake in
946 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
948 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
950 --- 4.0.10 2010/06/18
952 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
953 result set from a connection. The result set will be on its own
954 thereafter; no operations on it will perform retrievals from a target.
955 Only cached copies are returned.
957 ZOOM C:fix case for HTTP servers responding with Connection:close.
958 Ensure that if there is a current task it is resumed (like fetching
959 more records in a result set) . Bug #3484.
961 PQF parser: use odr_atoi for Odr_int (not atoi)
963 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
964 values that contain any non-digits are treated as string attributes
965 (previously decoding only checked for leading character ([0-9]). PQF
966 encoding: attribute string values are not surrounded by double-quotes.
970 New utility for managing threads - thread_create.h.
972 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
973 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
974 but YAZ' implementation do.
976 Fixes for yaz_cond-functions on Windows 7.
978 DLL export more symbols.
980 zoomsh: show record do NOT render opac.
982 Remove *.la files from Debian and RPM packages.
986 Debian package libyaz-dev depends on libgnutls-dev again (was
987 removed in YAZ 4.0.6, but due to Libtool it is still needed
988 even though yaz-config do not list libgnutls libs).
990 ZOOM: Use only one WRBUF for returning string results for
991 ZOOM_resultset. Reduces memory usage for ZOOM in general.
993 ZOOM: ZOOM_connection do not use a shared pointer to
994 ZOOM_resultset after ZOOM_resultset is destructed by
995 user. Reverts to YAZ 4.0.4 behavior.
999 record-conv: fix problem with at least one XSL conversion -
1000 due to probably incorrect usage of XML XSL documents.
1002 --- 4.0.6 2010/04/29
1004 Fix yaz-config for static mode and the use of SSL (gnutls).
1006 --- 4.0.5 2010/04/29
1008 Forward decl timeval struct in mutex.h and gettimeofday.h.
1010 yaz-config: fix 'static' mode linking.
1012 --- 4.0.4 2010/04/28
1014 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1015 are wrappers for pthreads or Windows. For Windows these are put in
1016 a separate DLL: yaz_cond4.
1018 libyaz.la (whole source) is compiled with thread. If thread support
1019 is enabled enabled, all source of YAZ is compiled with treading support.
1020 This allows core utilities such as yaz_log to use thread facilities.
1021 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1022 thread utilities. This commit moves mutex utilities (mutex.c) from
1023 libyaz_server.la to libyaz.la.
1025 yaz-json-parse displays leading text until error.
1027 --- 4.0.3 2010/04/09
1029 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1030 patch from Giannis Kosmas.
1032 SRU: no longer URL encode SRU database. The URL for an SRU server is
1033 a URL and such is alreeady encoded - at least when given with leading
1034 http:// or https://. This reverts behavior to YAZ 3.0.50.
1036 Support for new MARC XML notation TurboMARC which like MARCXML is a
1037 complete representation of MARC/ISO2709.. This one, however, is more
1038 compact and allows for faster processing with XSLT. TurboMARC can be
1039 used in the marcdisp.h API, from the yaz-marcdump utility and from
1042 yaz-ztest can be configured - via the database - to perform certain
1043 delays when it performs operations search, present and single record
1044 fetch. This allows testers to make yaz-ztest act as a real or even slow
1045 Z39.50 server. Refer to the yaz-ztest man pages for details.
1047 --- 4.0.2 2010/03/09
1049 wrbuf_destroy allows NULL WRBUF passed to it.
1051 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1053 Add ZOOM_connection_close.
1055 No fixed size buffers for ZOOM shell - bug #3257.
1057 tstodr: make it work on s390 platform.
1059 New icu iterator-functions. The new icu_iter-functions makes it possible
1060 to use ICU chains from many threads.
1062 yaz-client: better syntax check for show command.
1064 --- 4.0.1 2010/01/26
1066 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1069 New simple local-file XML include facility which allows file glob-patterns.
1070 Refer to yaz/xml_include.h.
1072 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1075 ZOOM_record_get supports new parameter "format" which makes it format XML
1078 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1079 JSONText in ECMA-262) is JSONValue, not JSONObject.
1081 --- 4.0.0 2010/01/20
1083 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1084 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1086 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1087 POSIX/Unix builds .so with major version 4.
1089 Remove old LOG_-defines from log.h. They have been obsolete and
1090 undefined by default for the last 5 years.
1092 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1094 GFS: Remove socket (int *fd) from search_rr handler. The socket
1095 descriptor ptr is a facility that allowed a search handler to supply
1096 a socket which would serve as a callback - when search was complete.
1097 This facility has now been in use for years.
1099 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1100 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1101 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1102 returns 'const char *' rather than 'char *. The returned string is
1103 read-only and should not be modified by applications. COMSTACK cs_close is
1104 now a void function - it no longer returns int. No applications check for
1105 the value and the implementations has always returned 0.
1107 ZOOM: use size_t for scan hit counts and str size. Functions
1108 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1109 occ (hit count) and len (string length) are now of type size_t pointer
1110 rather than int pointer. This is to be able to represent large hit counts
1111 and to also just to use the proper type for string length (strlen result).
1113 New JSON parser. Refer to include/yaz/json.h .
1115 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1116 Used to be int in some cases. Many wrbuf_-functions used to return an int
1117 indicating some length.. These return values were never used. And so they
1120 ODR: odr_malloc, odr_total now takes size_t for size.
1122 clone_z_type: fix leak; occurred for encoding failures.
1124 --- 3.0.52 2009/12/03
1126 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1127 bug was introduced in 3.0.51.
1129 --- 3.0.51 2009/12/02
1131 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1133 tcpip comstack: fix leak for getaddrinfo.
1135 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1136 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1137 Decoding of SRU "path" database is performed by private function
1138 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1139 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1141 yaz-client: honor base command for SRU. Change when database setting
1142 is applied for SRU and ensure it is kept when a connection is reset.
1143 Change also the way errors are displayed or SRU (decoding of packages).
1145 --- 3.0.50 2009/11/02
1147 Add support for extra request / response data for SRU codecs and GFS.
1148 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1149 for extra data response buffer and length. For the GFS, both request
1150 and response data (XML) is carried in extra_args and extra_response_data
1151 for the search handler. Patch by Ko van der Sloot.
1153 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1154 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1155 10010). This fixes bug #2113.
1157 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1158 cmdfile included a 'quit' command that would result in a memory violation.
1160 --- 3.0.49 2009/10/01
1162 Make a number of functions defined in xmlquery.c static. These have
1163 never been declared in a public header file (yaz/xmlquery.h) and was
1164 made public by mistake.
1166 Improve speed of character conversions (iconv utilities). This makes
1167 conversions from MARC-8 faster.
1169 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1170 unless type desired is "raw". This will prevent type "xml" from
1171 returning ISO2709 .. Which obviously can not be XML parsed.
1173 Fix memory leak in ZOOM that would occur if option apdulog was used
1174 on a re-used connection.
1176 Frontend server logs HTTP requests.
1178 Frontend server now sends Z39.50 close when it times out (sesssion has
1179 been idle for too long). Versions 2.0.30 and earlier also sent close.
1180 But due to a mistake this was disabled in all versions after that, i.e.
1181 the server would just close the socket immediately.
1183 yaz-client emits a better message when receiving an unrecognised
1184 userInformationField.
1186 Skip zero-length subfields when decoding ISO2709. This rare case happens
1187 if a record has two FS characters in a sequence. Without this patch
1188 there would be a reference beyond char array in using_code_len fragments
1191 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1193 --- 3.0.48 2009/08/28
1195 The show command offered by the zoomsh command now takes a 3d optional
1196 parameter type which is what is passed to ZOOM_record. If the type
1197 argument is omitted, "render" is used.
1199 RPN to CQL conv may use USE string attributes (bug #2978).
1201 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1203 --- 3.0.47 2009/07/08
1205 Function yaz_xml2query allows a diagnostic element in the PQF XML
1206 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1207 code and additional info respectively.
1209 The BER BOOLEAN is now the integral type Odr_bool which still happens
1210 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1211 typedef'd to Odr_int. This is still an integral 'int', but it may be
1212 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1213 ASN-1 compiler as well as programs has been updated to use the new types.
1215 --- 3.0.46 2009/06/08
1217 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1218 only the bibliographic record was rendered. For type=opac, an OPAC
1219 record is only returned if it is present.
1221 iconv: small fix for encoding of advancegreek.
1223 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1225 yaz-client: option auto_reconnect=on really reconnects.
1227 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1229 server: avoid null ptr ref for for yaz_poll errors.
1231 build: fix RPM build for RHEL 5.3.
1233 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1235 --- 3.0.45 2009/03/31
1237 Fixed bug #2709: TCP connect returns Invalid argument.
1239 Fixed compilation for mingw.
1241 Honor charset for raw records (ZOOM_record_get).
1243 Fixed use of errno for threaded mode that was seen on Solaris 10.
1245 Fixed argument passing with blanks in value for Windows Service.
1247 Disable YAZ' own log rotate by default (no 1 GB limit).
1248 The variable l_max_size which specifies the log file limit is set to 0
1249 (DISABLED): This is due to the fact that YAZ is most often deployed using
1250 logrotate. Also YAZ can not perform log rotate because of unsufficient
1251 permissions (setuid).
1253 --- 3.0.44 2009/02/17
1255 List supported encodings in man page for yaz-iconv.
1257 Fixed missing SSL libs for --libs output
1259 Re-established OID record syntax application-xml. Nobody should use it
1260 but we don't want to change soname because of this symbol being absent.
1262 --- 3.0.42 2009/02/02
1264 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1266 Added member named_result_sets for init handler struct for the GFS. This
1267 allows a server to disable named result sets.
1269 Removed OID record syntax application-xml.
1271 Added support for rule-based transliterator for ICU wrapper of YAZ.
1273 Fixed bug #1902: yaz-icu XML output.
1275 Make YAZ checks Emacs friendly.
1277 BITSTRING value shows value. Bug #2346.
1279 ISO2709 decoding: skip control characters from indicator data.
1281 Omit sort key by default in yaz-icu's output.
1283 Allow combined single char options (again) for YAZ' options function.
1285 Utility yaz-marcdump got option to display YAZ version (-V).
1287 Allow YAZ to use ICU 3.4.
1289 Added new ICU test case which illustrates removal of diacritics.
1291 --- 3.0.41 2008/12/29
1293 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1295 --- 3.0.40 2008/12/29
1297 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1300 Fixed bug #2352: yaz-marcdump crashes for certain record.
1302 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1304 Added support for Danmarc2 to UTF-8 conversion.
1306 Added support for ISO5426 to UTF-8 conversion.
1308 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1309 implementation version.
1311 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1313 --- 3.0.38 2008/11/10
1315 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1316 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1318 ZOOM C now interprets databaseName option for ZOOM connection as path
1321 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1323 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1325 Dummy Libxml2 types no longer defined in headers of YAZ'.
1327 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1330 --- 3.0.36 2008/09/26
1332 Various ODR chapter fixes.
1334 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1336 Added missing source for Windows compilation, mutex.c.
1338 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1340 For SRU connections in ZOOM all records up to "count" are now fetched.
1342 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1343 in Windows due to bad error handling for Libxml2.
1345 Added facility for sending arbitrary records (ASN.1 any) using
1346 ZOOM C's Extended service update. Patch by Sam Reynolds.
1348 New options for ZOOM C's connection, logapdu which makes ZOOM log
1351 --- 3.0.34 2008/06/18
1353 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1355 --- 3.0.32 2008/06/12
1357 Fixed memory violation that could occur when decoding UTF-8. This bug
1358 was only present in 3.0.30 of YAZ.
1360 --- 3.0.30 2008/06/06
1362 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1363 GNU TLS is used by default (if found).
1365 yaz-ztest returns OPAC records if a client asks for OPAC.
1367 Improved speed of MARC-8 encoding.
1369 Added support for lossy and loss-less MARC-8 encoding.
1371 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1373 Added new Windows Service wrapper (sc).
1375 yaz-client's itemorder command may now send a file.
1377 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1379 Added new function yaz_log_xml_errors.
1381 Allow (but warn) unknown XML attributes in MARCXML parsing.
1383 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1385 The UTF-8 to MARC-8 conversion now uses a different set of characters
1386 for Greek symbols. Bug #2120.
1388 --- 3.0.26 2008/02/21
1390 Added yaz_daemon (daemon.h).
1392 Fixed bug #2068: pkg-config trouble
1394 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1396 --- 3.0.24 2008/01/28
1398 Document --with-xml2 option.
1400 Added OPAC XML XSD (etc/opacxml.xsd).
1402 Allow glob mask for name attribute in retrieval element for the
1403 generic frontend server's retrieval facility.
1405 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1406 except POLLIN/POLLOUT.
1408 Fixed error handling in cs_listen. Bug #2037.
1410 --- 3.0.22 2008/01/20
1412 Fixed version in yaz/yaz-version.h.
1414 Fixed bug #2027: Crash when closing connection.
1416 Changed configure so that ICU support is only enabled if only ICU
1417 and Libxml2 is available (because the ICU chain is XML based).
1419 --- 3.0.20 2008/01/15
1421 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1422 is built. Only this DLL depends on the ICU runtime.
1424 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1425 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1427 Changed license of CCL module to 'Revised BSD'. After consultation with
1428 remaining members of the original EUROPAGATE consortium, we are re-issuing
1429 the CCL module without a separate license. The software was developed by
1430 Index Data as part of a research project. The special license was included
1431 to help feed usage information back to the project consortium to support
1432 project evaluation. At this time, the project consortium has long-since
1433 disbanded, and the majority of the original principals have retired. At the
1434 same time, we have significantly modified the software during the following
1435 years, to the point where very practically no original code remains. To
1436 simplify re-use of the software, we have contacted those members of the
1437 consortium who could be reached, and agreed to re-issue the module as a
1438 proper part of the YAZ package.
1440 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1442 CQL closer to being version 1.2 compliant. CQL also allows free-form
1443 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1446 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1447 bug could make Extended services handling crash in the ZOOM layer. This
1448 bug was only present in YAZ 3.0.18.
1450 --- 3.0.18 2007/12/19
1452 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1455 yaz-marcdump reads and writes collection wrapped records.
1457 Handle OPAC for record conversion module.
1459 Fixes for ICU wrapper.
1461 Allow ICU libs to be controlled with --with-icu .
1463 --- 3.0.16 2007/11/12
1465 Added yaz_poll which is a wrapper for select/poll. When poll is available
1466 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1467 sockets to be in use.
1469 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1470 functionality through an XML based configuration (ICU chain). This system
1471 is useful for search facilities such as Pazpar2 and Zebra that needs to
1472 perform tokenization of indexed material. The ICU code in a separate
1473 library libyaz3_icu.a.
1475 Added HTTP tunnel facility for COMSTACK, bug #1752.
1476 This is a facility that allows a Web proxy, such as squid, to tunnel
1477 Z39.50 traffic. This facility is "transparent" to must applications
1478 using YAZ. It's enabled by using pseudo transport connect: followed by
1479 the proxy address, followed by command, then follwed by he regular
1480 "virtual" addresss. For example,
1481 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1483 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1485 --- 3.0.14 2007/09/21
1487 Fixed bad memory reference in ZOOM_record - cuased by member not being
1488 initialized. This was a problem only in YAZ 3.0.12.
1490 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1491 fields were not removed.
1493 Changed the way C code is generated from codetables.xml. Made a MARC-8
1494 conversion trie for each characterSet section rather than codeTable.
1495 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1496 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1498 --- 3.0.12 2007/09/12
1500 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1501 from ZOOM_record_error).
1503 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1505 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1507 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1509 Better SRW-to-Bib-1 diagnostic mapping.
1511 ZOOM C and yaz-client announces SRU version 1.2 by default.
1513 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1516 Fixed in yaz_sru_decode to allow other version than 1.1.
1518 --- 3.0.10 2007/08/22
1520 Added support for SRU scan for ZOOM.
1522 Added support for the use of the older versions or Extended Service
1523 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1524 set to the version , 1=first, 2=second, 3=third. The third version is
1525 what ZOOM C has used so far. And that, obviously, is the default.
1527 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1528 therefore in Zebra and in SimpleServer-based applications). The new
1529 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1530 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1531 which is passed into the back-end search callback function.
1533 Added support for HTTP Basic authentication in clients: the SRU/W
1534 codec encodes the username/password elements of the PDU structure
1535 appropriately, and these may be set using the "user" and "password"
1536 options in ZOOM-C applications (the same options that are used for
1537 Z39.50 authentication).
1539 --- 3.0.8 2007/06/25
1541 Fixed bug #1208: SSL appears to be broken in ZOOM.
1543 Fixed bug #1206: Libxml2 include path weirdness.
1545 Added oid_name_to_dotstring.
1547 Allow elementSetName to be specified for ZOOM C record update.
1549 Allow waitAction to be specified for ZOOM C based for Extended Services.
1551 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1552 syntax OID. Bug introduced in YAZ 3 series.
1554 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1556 --- 3.0.6 2007/06/06
1558 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1559 directory. yaz-client now reads commands from file given by option -f
1560 if specified; then tries to read .yazclientrc in current directory.
1561 Failing that, it reads .yazclientrc from user's home directory.
1563 Added support for correlationInfo Note and ID for Record Update via
1566 Added yaz-client command querycharset which specifies character set for
1567 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1568 (termListAndStartPoint).
1570 Charset ISO5428:1984 is an alias for ISO5428-1984.
1572 Implemented a way to perform scan in a result set using Z39.50. This
1573 is achieved by attaching the result set name in the characterInfo
1574 (type InternationalString) of OtherInformation in the Scan Request PDU.
1575 The result set is identified in the otherinformation by the new OID:
1576 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1577 This allows for scan in result set and faceted search . Zebra did some
1578 of this in the APT term using attribute type 8 and value being result
1579 set. Using the OtherInformation approach for this is cleaner and easier
1580 to work with in proxies and the like. This facility can be used in
1581 yaz-client using new command setscan which takes a result set as first
1582 argument, start position (APT) as second.
1584 Changed decoding of SRU XML packed records to deal with servers that
1585 have recordData with XML data with multiple root nodes. Also make
1586 comparison for recordPacking case insensitive. Again, one server
1587 returns "XML" where others return "xml".
1589 For SRU responses allow Content-Type application/xml as well as text/xml.
1591 --- 3.0.4 2007/05/21
1593 Fixed bug in character set conversion of BER strings. Bug introduced
1596 --- 3.0.2 2007/05/08
1598 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1600 For OID class, use oid_class consistently.
1602 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1605 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1606 character set for bibliographic information interchange". By Giannis Kosmas.
1608 Added documentation on new OID API.
1610 --- 3.0.0 2007/05/02
1612 Changes to generic frontend server interface: added new member
1613 'query_charset' for bend_initrequest structure. A backend init handler
1614 should set this member to its native character set for query terms.
1615 When defined, the frontend server logic will announce this character set
1616 to a client if the negotiationModel bit is set by the client. All server
1617 implementors are encouraged to specify this. If a backend server does not
1618 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1620 Added CCL utility to remove terms (stop words) from resulting RPN
1621 tree. This is handled by functions with prefix ccl_stop_words_ .
1623 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1624 terms in RPN queries.
1626 Clean-up the CCL API. Moved some internal structures from ccl.h to
1627 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1628 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1629 This is replaced by ccl_parser_find_str which takes a string instead.
1631 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1632 libyaz.la is the core of YAZ except the generic frontend server and
1633 does not depend on POSIX threads anymore. libyaz_server.la is the
1634 generic frontend server facilities and uses POSIX thread functionality
1635 if available. The libyaz.la no longer depends on POSIX threads because
1636 the number of global structures is limited. NMEM no longer re-uses blocks
1637 between threads ; it simply free's memory immediately but allocates in
1638 "large" chunks as usual. We don't expect any performance penalties
1639 because of this. The yaz_log system is still using a global log_level so
1640 caution must be taken when modifying it with yaz_log_init_.. +
1641 yaz_log_mask_str. This, however, should not cause any trouble because
1642 these functions are called during initialization of application code
1643 anyway. `yaz-config --libs server` returns libs for server applications;
1644 `yaz-config --libs` returns libs for non-server applications.
1646 New OID database - with public definitions in oid_db.h. Removed old OID
1647 database including the head oid.h and definitions such as enum oid_value
1648 and struct oident. The new OID database uses the same string names as
1649 before but the 'protocol' is gone. There are now only two representations
1650 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1651 converts from string to OID; functions with prefix yaz_oid_to_string
1652 converts the other way.
1654 Change to emit_term() in CQL-to-PQF query translation: when a term has
1655 the /regexp relation modifier, do not process it for leading and
1656 trailing "^" and "*", which have quite different meanings in regular
1659 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1660 write handlers no longer carries a 'last' parameter. This will make
1661 yaz_iconv flush "less" characters. A flush is performed by call to
1662 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1664 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1665 removed, because function yaz_query_to_wrbuf does the same.
1667 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1668 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1670 Deprecated MARC utility functions removed.
1672 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1675 Branch split: YAZ_2_1_55_branch
1677 --- 2.1.54 2007/03/16
1679 Fix to ZOOM-C so that transparent reconnection is properly handled on
1680 connections that are in asynchronous mode.
1682 Fixed compilation on OpenBSD 4.0.
1684 Large strings in GRS-1 records are now properly displayed in yaz-client.
1686 Added character conversion support for "advancegreek"; based on patch from
1689 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1690 sequence is met. Before the error was not set so it would be unknown.
1692 Adjust yaz-marcdump MARC reader so that it skips until record separator
1695 --- 2.1.52 2007/03/07
1697 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1698 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1699 fd_set structure used as a bitmask for the FDs to be selected on.
1701 Using ACX_PTHREAD macro to check for POSIX threads.
1703 Fixed have-vsnprintf check.
1705 --- 2.1.50 2007/02/23
1707 Fixes for configure on BSD. Bug #900.
1709 Added snprintf/vsnprintf wrappers for systems that don't have
1710 limits (heavens forbid).
1712 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1713 created before all previous tasks were completed and removed from the
1714 task queue, the new task could be removed by a mistake.
1716 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1718 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1720 Fixed bug #832: Problem with MARC/charset in yaz-client.
1722 Fixed bug #668: save command line history for yaz-client.
1724 Fixed bug #830: pkg-config support.
1726 --- 2.1.48 2007/01/23
1728 Extended ZOOM result set options with two options that may be read by
1729 a client: resultSetStatus and presentStatus with values as specified for
1731 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1733 Fixed bug #827: Using SSL fails on Debian etch.
1735 Fixed bug #826: Weird looking chars for set of MARC records.
1737 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1738 that is treated as an ItemOrder with itemRequest being an XML document
1739 external. The value of "doc" is the content.
1741 Extended the GFS search facility. New member of bend_search_rr
1742 'estimated_hit_count' signals that hits is known to be an estmate
1743 (higher or lower than real hit count). New member 'partial_resultset'
1744 signals that the search was partial (hit count is lower or equal than
1745 real hit count). For Z39.50, the information is stored in resultSetStatus
1746 member of SearchResponse APDU. For SRU, the information is signalled
1747 via SRU diagnostic 59: "Result set created with valid partial results
1750 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1752 --- 2.1.46 2007/01/13
1754 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1756 Added ZOOM_connection_peek_event.
1758 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1759 the following new functions:
1760 ZOOM_event_nonblock, ZOOM_connection_process,
1761 ZOOM_connection_get_{socket,mask,timeout},
1762 ZOOM_connection_fire_event_{timeout,socket}.
1763 The existing blocking event handler, ZOOM_event, is a wrapper for the
1764 + blocking ZOOM_event_sys_{poll,select}.
1766 Implemented function ccl_xml_config which parses XML version of CCL
1767 configuration (bug #798).
1769 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1771 Added timings utility (yaz/timing.h)
1773 --- 2.1.44 2007/01/03
1775 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1778 Fixed bug #779: Rotation of apdu.log fails.
1780 Fixed for character set conversions:
1781 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1782 Honor G1 set in MARC-8 decoding.
1784 --- 2.1.42 2006/12/17
1786 Fixed bug #775: char conversion does not handle Alternative UTF-8
1789 Implemented function yaz_marc_read_line which parses MARC line format
1790 records. There is a wealth of formats out there. So far, this function
1791 reads line records produced by yaz_marc_write_line.
1793 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1794 more generic and easier to remember(!) options: -i format and -o format
1795 which specifies input format and output format respectively - where
1796 format is one of "marc", "marcxml", "line", "marcxchange".
1798 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1799 does not print anything except warnings for records.
1801 For yaz-marcdump, added support for MARC split into files (-s) with a given
1804 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1805 spec, at http://www.loc.gov/standards/sru/record-update/
1806 This has changed the binary layout of the following structs:
1807 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1808 bend_update_rr . Patch by Ko van der Sloot.
1810 Added GFS utility function bend_assoc_is_alive which returns 1 if
1811 association is still alive (client is connected); 0 otherwise (client
1812 closed connection). This allows busy servers to stop working for
1815 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1816 been a separate piece of software. This version of ziffy has been modified
1817 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1819 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1821 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1822 Client code may now interrogate options such as "init_opt_sort" to
1823 find out whether the server claims to support various options.
1825 --- 2.1.40 2006/11/27
1827 Added utilities yaz_{set,get}_esn to set/get element set name from
1830 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1831 of YAZ and has been so since YAZ 2.1.10.
1833 Implemented ZOOM_record_error which returns error information for
1834 record (surrogate diagnostic).
1836 --- 2.1.38 2006/10/31
1838 Updates for SRU Update by Ko van der Sloot:
1839 1. Changed name from "operation" to "action"
1840 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1841 versions in the code, marked as 'backward compatible'.
1842 3. Added diagnostics for SRU Update.
1844 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1846 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1848 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1850 For GFS, fixed problem with SRU diagnostic 'First record position out of
1851 range' being issued for 0 hits.
1853 zoomtst10 part of Windows Build.
1855 --- 2.1.36 2006/10/13
1857 Implemented yaz_filepath_comp which splits a path into file path
1858 components (required by Zebra 2.0.3+).
1860 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1861 BSD inspired license until now so this should not have any real impact on
1862 anybody. See http://www.opensource.org/licenses/bsd-license.php
1864 Fixed bug #687: Missing log lines.
1866 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1869 Fixed bug #689: SRU diagnostics to be added.
1871 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1872 whether a connection is idle (no more work do do).
1874 --- 2.1.34 2006/10/04
1876 Change type of optval from long to int for invocation of setsockopt with
1877 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1879 Added support for specifying the max log file size for the Generic
1880 Frontend Server. The size is given with option -r.
1882 --- 2.1.32 2006/09/21
1884 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1886 --- 2.1.30 2006/09/17
1888 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1891 Fixed bug in Generic Frontend Server that could cause a server to stop
1892 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1894 For the generic frontend server, the maximum record size is used as maximum
1895 size of incoming packages (SRU + Z39.50). The value until was previously
1896 only used in Z39.50 Init negotiation and, later, in a session controlled
1897 sizes of records returned. This is controlled using -k option. It can be
1898 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1900 --- 2.1.28 2006/09/04
1902 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1905 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1907 New option for yaz-marcdump -lpos=value which allows setting a portion
1908 of MARC header to a certain value.
1910 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1912 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1913 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1915 --- 2.1.26 2006/08/15
1917 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1920 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1922 --- 2.1.24 2006/08/08
1924 Fixed MARC ISO2709 encoding routines to deal with character set
1927 Minor changes to GFS logging. Database included in search request log
1930 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1931 cached/multiple records.
1933 Shared libraries are built by default on Unix+configure.
1935 Changed cql2pqf transformation to use a different evaluation order. The
1936 new order is: always, relation, structure, position, truncation, index
1937 and relationModifier. Old order was: always, relation, relationModifier,
1938 structure, index, position, truncation. Note that the the latter ones
1939 override former ones for identical attributes.. The new scheme means that
1940 it is possible to override any existing attribute with a relationModifier.
1941 And also that it is possible to override everything for the index rule
1942 (except the ones listed in relationModifier). No order is perfect but this
1943 one, we believe, covers more real cases.. The "always" should have been
1944 called "default", since the attributes there can be overridden with all
1947 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1948 compilation phase, but also for yaz-config --cflags output. This allows
1949 us to have public headers with Libxml2 stuff in them . It should also,
1950 eventually, make Libxml2 checks redundant in packages using YAZ, such
1953 --- 2.1.22 2006/06/15
1955 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1956 stored in uri, message and details.. Previously diagnostics were stored
1957 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1958 compatibility.. but he's probably the only one affected, so.
1960 Added support for CCL, compiled on the client side, in ZOOM-C. This
1961 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1962 input; the resulting query objects can be used for for searching with
1963 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1965 YAZ' configure searches for OpenSSL by default.
1967 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1968 SL_CTX_use_certificate_file. See
1969 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1970 for more info. Thanks to Ko van der Sloot.
1972 --- 2.1.20 2006/06/02
1974 Bug #600: SRU GET, POST support for yaz-client. Introduced
1975 command 'sru' which selects method SOAP/GET/POST.
1977 Allow missingValueAction to be specified for the sortspec string -
1978 function yaz_sort_spec. By default, the missing value action is null.
1979 Use ! to specify "abort". Use = followed by stringvalue to specify default
1982 Ensured that Present-handler (if defined) is called in GFS before any call to
1983 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1984 searchRetrieve requests.
1986 Documentation for YAZ is now based on the Docbook XML/XSLT using
1987 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1988 is no longer depending on jade/openjade or docbook-to-man scripts.
1989 PDF is no longer part of the distribution - but can optionally be
1990 made using DSSSL/jadetex or FOP.
1992 Added retrieval handling support in Generic Frontend Server to support
1993 conversion between MARC/XML as well as XSLTtransforms. See
1994 etc/yazgfs.xml for an example.
1996 Added Authentication support to Generic Frontend Server in SRU
1997 mode. Authentication using HTTP Basic is supported, as is the use
1998 of 'x-username' and 'x-password' parameters in the request itself.
2000 Added support for a new character set MARC8s identical to MARC8 except
2001 that it converts combined characters to single Unicode characters in the
2002 Latin-1 range (when possible).
2004 --- 2.1.18 2006/04/24
2006 ASN.1 compiler 0.4: generates brief Doxygen file header for
2007 generated .h/.c files.
2009 Utility yaz_iconv now supports conversion to MARC-8.
2011 New facilities for the MARC module. The reading - and writing of
2012 content are separate methods for the yaz_marc_t handle. The following
2013 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2014 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2015 format). Write functions have prefix yaz_marc_write_.. The existing
2016 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2017 available. Removed support for OAI-MARC and simplexml (not the
2018 simplexml from PHP5).
2020 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2021 to be returned for this connection.
2023 --- 2.1.16 2006/03/31
2025 Allow multiple languages and charsets to be specified with
2026 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2027 negcharset iso-8859-1,utf-8
2029 Translation of proximity nodes from CQL into PQF now works.
2031 Moved to automake 1.8, 1.9.
2033 Added function yaz_log_set_handler which allows a log handler to be
2034 installed. This handler will be called for all log messages. Output
2035 to file is also produced; but that can be disabled by passing NULL
2036 fname to yaz_log_init_file.
2038 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2040 For SRW (including GFS), accept application/soap+xml as content-type
2043 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2044 produces NO stylesheet reference even if a default stylesheet is specified
2047 --- 2.1.14 2006/03/14
2049 Updated Windows package to include yazd.dll + yazd.lib for the
2050 Development component.
2052 If the environment variable YAZ_LOG is set, then it is used as a
2053 string indicating the default level of logging to use if not
2054 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2055 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2056 used as before. So, for example, to omit warnings from YAZ logging,
2057 export YAZ_LOG=-warn
2059 cql_transform() now map structure and other attributes before indexes,
2060 so that index-specific structures and other attributes can override
2061 defaults. So now a combination of mapping specifications such as:
2063 index.dc.date = 1=date-modified 4=5
2064 does the right thing.
2066 cql_transform() now also respects the "always" mapping specification,
2067 which establishes an initial set of attributes to be used for all
2068 terms except where overridden by more specific attributes associated
2069 with the index, relation or modifier.
2071 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2072 which mode to use; one of "post", "get" or "soap" (SRW, default).
2074 Fixes for yaz_iconv routines: changed trie-based character set conversions
2075 to use only non-negative values for bit fields due to Sun's C compiler not
2076 supporting negative values.
2078 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2079 sequences where not read correctly. Fix by Rustam Usmanov.
2081 Updated win/makefile to use options, settings which makes things
2082 compile with VS C 2005.
2084 --- 2.1.12 2006/02/01
2086 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2088 In ZOOM socket code, use select instead of poll on MacOSX.
2090 ZOOM-C now support client-side compilation of CQL into RPN that is
2091 sent to the server, enabling CQL to be used against all Z39.50
2092 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2093 ZOOM_query object, and submit it using ZOOM_connection_search().
2094 The CQL-to-RPN translation uses a configuration file, the name of
2095 which must be specified in the Connection's "cqlfile" option.
2097 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2098 function, which takes as its start-term parameter a ZOOM_query object
2099 (which may have had either CQL or RPN set into it).
2102 --- 2.1.10 2005/11/29
2104 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2105 GFS to support this as well. Backend handler, bend_srw_update, does the
2106 update work. Code contributed by Ko van der Sloot.
2108 Allow retrieval of Search Result-1 information in ZOOM by the use of
2109 options that are attached to a result set. ZOOM documentation updated
2112 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2113 UTF-8 conversion. Patch by Raj Patel.
2115 Added option -m to GFS to control formatting of timestamps in log file.
2117 Added 'exit' as synonym for 'quit' in yaz-client
2119 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2120 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2121 for the new members. Patch by Ko van der Sloot.
2123 Added support for SRU POST. It is supported for content-type
2124 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2126 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2127 Instead make the library libyaz.la multi-threaded. Threading as a whole
2128 can still be disabled by configure option --disable-threads. Previosly,
2129 with older GLIBCs there were problems with MT libs under Apache. This
2130 has now been fixed a long time ago.
2132 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2135 CQL module modified to be case insensitive for relations/indexes/operations.
2137 Fixed bug in CQL transform code: incorrect value relationModifieder
2140 Added 'show all' command for yaz-client which retrieves all results
2143 Added new yaz-client, xmles, which takes a (private) OID and
2144 a document to be sent as an extended service request.
2146 Describe new yaz-client commands wait_response and set_auto_wait.
2148 Increase TCP/IP listener backlog from 3 (which I am guessing was
2149 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2150 that the socket will queue as many incoming connections as it's able
2151 to handle ongoing connections. In other words, it will never now
2152 refuse a connection that it would be able to handle merely because
2153 it's not got around to accepting() enough of the pending connections
2154 yet. This is the behaviour anyway under Linux, where the listen()
2155 argument is ignored; but not under BSD and on systems such as
2156 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2157 YAZ-based servers should now be uniform across operating systems in
2160 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2161 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2162 This allows yaz-marcdump to read large MARC batches (>2 GB).
2164 Modified all YAZ source files - except the source which is auto-generated
2165 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2168 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2169 corresponding to the existing *_setl() function. These allow option
2170 values containing arbitrary valuues.
2172 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2173 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2174 except that it returns an indicator of whether or not the sort
2175 criterion was accepted (0 for OK, -1 for invalid).
2177 --- 2.1.8 2005/06/07
2179 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2180 MARC output rather than returning "new" buffer.
2182 yaz-client warns about unknown init options.
2184 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2186 --- 2.1.6 2005/05/24
2188 Added support for SRW sort in Generic Frontend Server. Patch
2189 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2190 sortKeys - or NULL if none is provided.
2192 Fixed bug #307: It was impossible to specify indefinite/no timeout
2193 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2196 Added support for multiple languages and charsets to be specified in
2197 ZOOM. Each charset/language is separated by a blank. If negotiation is
2198 in effect in init-response, Option
2199 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2200 Code based on patch by Vasiliy Osadchuk.
2202 Fixed bug #306: infinite recursion that occurred when calling
2203 yaz_log_level_init as the first call (before other log level or
2206 Fixed bug in scan handling in front end server: if preferred-Position-In-
2207 Response was non-present, a NULL pointer referece was performed.
2209 --- 2.1.4 2005/04/26
2211 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2212 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2213 now defined for all those error codes. So instead of putting 109 in
2214 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2215 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2217 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2220 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2222 Program yaz-client now exits and produces an error message if multiple
2223 Z39.50 servers are specified on the command line (none or one allowed
2226 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2229 --- 2.1.2 2005/03/16
2231 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2233 Fixed bug #272: Preserve spacing for CCL terms.
2235 --- 2.1.0 2005/03/14
2237 Added support for virtual hosts and multiple backend servers for
2238 the YAZ frontend server. The configution is XML based and
2239 support specificition of CQL to RPN mappings and explain information.
2240 See section "Virtual Hosts" in the YAZ manual.
2242 Extended OPAC display utility. OPAC display utility renders
2243 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2244 to supplement yaz_marc_decode_wrbuf.
2246 Fixed a bug in MARC decoder that could caused it to crash for some
2247 invalid MARC records. More diagnostics and warnings where added in
2248 XML output (warnings, etc are stored in comments).
2250 --- 2.0.34 2005/02/08
2252 Fixes for UNIX domain sockets. Bug #261.
2254 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2256 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2257 Added yaz_marc_subfield_str which defines subfield lead string which is
2258 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2259 yaz_marc_endline_str which defines end of fields string used in
2260 YAZ_MARC_LINE format. Default string is newline.
2262 Experimental support for MarcXChange. This format can be produced
2263 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2264 http://www.bs.dk/standards/MarcXchange.xsd
2266 Added yaz-client commands scansize that sets maximum number of
2267 entries to be returned by scan.
2269 --- 2.0.32 2005/01/11
2271 Added support for SRW scan in yaz-client and Generic Frontend Server.
2273 * Added whereInList member to SRW Scan Term.
2275 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2277 Fixed NMEM system to return aligned blocks on the smallest boundaries
2278 that are suitably aligned for all possible types on the particular
2279 architecture YAZ is being built for.
2281 --- 2.0.30 2005/01/04
2283 Fixed numerious warnings that was issued with newer versions of GCC.
2285 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2286 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2289 Make YAZ Generic Frontend Server slightly faster.
2291 Enhance (and reduce) logging for Generic Frontend Server.
2293 Revert YAZ log system so that it flushes every write operation
2294 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2296 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2297 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2298 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2299 will effectively disable old definitions.
2301 --- 2.0.28 2004/11/09
2303 Added yaz_log_time_format which specifies log format using
2306 Added yaz_log_module_level which returns mask for a module. Value
2307 is non-zero mask a if module is enabled; zero if disabled.
2309 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2310 in include/yaz/cql.h.
2312 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2314 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2316 Fixed bug #172: RPM builds does not enable SSL.
2318 Doxyfile.in part of dist. Doxyfile generated by configure.
2320 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2321 are given and the corresponding component does not exist.
2323 Extend CCL documentation in YAZ reference. Describe r=r.
2325 --- 2.0.26 2004/10/01
2327 Fixed MARC->MARCXML conversion to properly deal with
2328 fields, subfields, indicators having non-ASCII characters.
2330 Fixed MARC->MARCXML conversion so that ASCII control characters
2331 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2334 Added YAZ GFS support for conversion from Z39.50 surrogate
2335 diagnostics to SRW surrogate diagnostics.
2337 Bug fix: YAZ GFS did not return schema in explainResponse.
2339 --- 2.0.25 2004/09/30
2341 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2342 now converts recordSchema to elementSetName as well as schema URI.
2344 Fixed bug in COMSTACK that prevented HTTP request packages from being
2347 --- 2.0.24 2004/09/29
2349 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2350 does not require white-space before and after the dash in a range, e.g.
2351 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2354 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2355 due to new GCC removing "redundant" code.
2357 Added yaz-client commands scanpos and scanstep that sets preferred
2358 position and step-size for scan.
2360 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2362 Added CCL utility ccl_qual_buf which parses one or more CCL
2363 spec lines in a buffer.
2365 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2366 of name and value - ignoring empty lines and comments.
2368 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2370 Added odr_get_element_path which returns current element path for an
2371 ODR handle. This utility is useful in error handling or user-defined
2374 Added ODR_PRINT utility odr_set_stream which is is a more generic
2375 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2376 to a write function and pointer to close function. The close function - if
2377 non-NULL - will be called during odr_destroy.
2379 Fixed bug in CCL parser where truncation char was not removed from
2380 right side when truncation=both was in effect.
2382 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2385 --- 2.0.23 2004/08/11
2387 Fix buffer overrun in CQL parser when dealing with proximity (%).
2389 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2390 to UTF-8/UCS conversion is now only based on codetables.xml.
2392 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2394 --- 2.0.22 2004/08/06
2396 Add support for more "commit changes" in ZOOM (uses Extended Services).
2398 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2401 Yet another small fix for configure of SSL.
2403 --- 2.0.21 2004/05/14
2405 Fix SSL libs for configure when --with-openssl=DIR is given.
2407 --- 2.0.20 2004/05/10
2409 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2411 SSL comstack now uses yaz.pem certificate file on server side
2412 by default. Certificate filename can be configured by calling
2413 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2415 Fix bug regarding multiple calls to ZOOM_connection_connect.
2417 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2419 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2420 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2422 ZOOM now allows inspection of X509 peer certificate for verification.
2423 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2425 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2426 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2427 as "modular" but it simplifies things.
2429 Added cs_get_peer_certificate to that returns peer X509 PEM.
2431 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2432 NULL if SSL is unavailable.
2434 Documentation about MARC decoding tools.
2436 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2438 --- 2.0.19 2004/03/30
2440 Rename CHANGELOG to NEWS to follow GNU style packing.
2442 Fix bug with missing initialization of member in init_diagnostics.
2443 This bug affects threaded version of GFS server.
2445 --- 2.0.18 2004/03/20
2447 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2450 Ensure zlib.dll is packed with Windows install.
2452 --- 2.0.17 2004/03/17
2454 Fix encoding of xsd:string to use text instead of CDATA.
2456 Fix endless loop in CQL parser with unbalanced ".
2458 Use a more compact way to store MARC-8 conversion tables.
2460 --- 2.0.16 2004/03/16 Debian only
2462 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2465 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2470 --- 2.0.15 2004/03/01
2472 Another fix for decoding of XML packed records.
2474 --- 2.0.14 2004/02/25
2476 Fixes for Chunked encoding. White space not ignored after length spec.
2478 Update NS and use default NS for SRW diagnostic elements.
2480 --- 2.0.13 2004/02/23
2482 Implement ZOOM_resultset_cache_reset which resets record cache.
2484 Implement ZOOM_resultset_sort which sorts a result set.
2486 Implement chunked HTTP transfer.
2488 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2490 --- 2.0.12 2004/02/16
2492 Added member 'schema' to bend_explain_rr structure so that backend
2493 can specify explain record identifier. Defaults to Zeerex 2.0.
2495 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2497 --- 2.0.11 2004/02/16
2499 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2502 Added init command for yaz-client which sends "extra" init request.
2504 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2505 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2507 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2509 Make ZOOM error code for "invalid query".
2511 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2513 --- 2.0.10 2004/02/05
2515 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2518 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2520 Added option -p <file> to make Generic Frontend Server to write PID file.
2522 Added option -D to put Generic Frontend Server in background on its own.
2524 Make ZOOM C recognize option "password". If unset, "pass" is used
2525 (for backwards compatibility).
2527 Fixed a bug in Generic Frontend Server that could make it crash if a
2528 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2531 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2532 Must be issued before open, in order to be in effect.
2534 --- 2.0.9-6 2004/01/12 Debian/Windows
2536 Make the SRU server more picky WRT unknown params, etc.
2538 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2540 New YAZ client command, options, that sets Z39.50 options.
2542 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2543 options from a string of tokens (one token for each option bit).
2545 Update SRW diagnostic code messages.
2547 --- 2.0.9-5 2004/01/07 Debian/Windows
2549 Handle user defined stylesheet for SRW/SRU.
2551 --- 2.0.9-4 2004/01/06 Debian/Windows
2553 Fix bug in decoding of Content-Length.
2555 --- 2.0.9-3 2004/01/06 Debian/Windows
2557 Fix a bug with decoding of XML packed records.
2559 --- 2.0.9-2 2004/01/05 Debian only
2561 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2563 Fix bug in SRW/SRU diagnostics decoding.
2565 --- 2.0.9 2004/01/05
2567 Fixed bug in Generic Frontend Server which could drop records exceeding
2568 preferred message size. Reported and fixed by Irina Dijour.
2570 Fixed calculation of package size for structured records in Generic
2571 Frontend Server. Reported and fixed by Irina Dijour.
2573 Fixed namespace for SRW/SRU diagnostics.
2575 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2577 --- 2.0.8 2003/12/22
2579 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2580 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2583 CQL changes to reflect recent changes to the specification:
2584 * Documentation talks about context sets instead of index sets.
2585 * Documentation talks about indexes instead of qualifiers.
2586 * The CQL-to-PQF transformer's configuration file now uses
2587 "index.set.name = <attributes>" instead of the old form
2588 "qualifier.set.name = <attributes>". (Both forms are still
2589 understood but the latter is deprecated.)
2590 * CQL terms with no explicit index specified are now interpreted as
2591 cql.serverChoice instead of srw.serverChoice (which of course
2592 behaves exactly the same.)
2594 --- 2.0.7 2003/12/16
2596 MARC conversion can now generate ISO2709 output in another
2597 character set. yaz-marcdump uses this facility if you invoke it
2600 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2601 functions from there can be used from C++.
2603 --- 2.0.6 2003/12/04
2605 Frontend server now transfers memory from decoded packages to stream
2608 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2609 references to show up.
2611 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2612 the ZOOM Abstract API. The older names for the same options are still
2613 also supported for the benefit of old applications.
2615 ZOOM-C supports "implementationId" and "implementationVersion" options
2616 to go along with "implementationName". These allow the user code to
2617 specify identification strings to be sent to servers.
2618 Add OID for the new ExtLite attribute set.
2620 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2621 as requested/supplid by Ere Maijala <ere@atp.fi>
2623 For generic frontend server, reverse the order of
2624 "toolkit-supplied / application-supplied" strings sent as implementationId,
2625 Name and Version. Also, remove the spaces around the slash. This brings
2626 the GFS in line with the behaviour of ZOOM-C on the client side.
2628 Add function ZOOM_scanset_display_term.
2630 yaz-client shows scan displayTerm if present.
2632 Utility yaz-iconv is now installed by default along with the man page
2635 Extend configure check for OpenSSL to use pkg-config where available (such
2638 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2639 server to specify uid/gid/mask for socket using the format
2640 unix:[user=uid,][group=gid,][umask=mask,]file=path
2641 If file= is omitted the existing format is assumed, e.g.
2643 in which case the mask is 0666 (rw for everybody).
2645 Major restructure of YAZ source. All source in libyaz is in src directory.
2646 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2647 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2649 Added man page for utility yaz-marcdump (used to be called marcdump).
2650 yaz-marcdump is installed by 'make install'.
2652 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2653 of incoming package failed.
2655 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2657 Change prototype of odr_perror: add const to message string.
2659 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2661 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2662 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2663 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2664 DNS lookup. There should not be any compatibility problems with this
2665 assuming that blocking=1 or 0 is used.
2667 Fix bad reference in UNIX comstack in function cs_addrstr.
2669 Fix for compilation on AIX.
2671 The generic front-end server (server/seshigh.c) now supports returning
2672 Init diagnostics to the client in User-information-field, in
2673 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2676 --- 2.0.4 2003/09/04
2678 Allow any CQL relation (not just all,any,exact,scr).
2680 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2681 that features the same UI.
2683 Implemented command update0 in YAZ client which is equivalent to
2684 update but uses old of Ext Update ASN.1.
2686 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2687 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2688 Previously no OID was used for this info.
2690 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2691 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2692 returns 'malformed search term' otherwise.
2694 SortResponse member resultCount now set to NULL in sort handler of
2697 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2700 Add three new utility functions for translating OIDs between various
2701 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2702 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2703 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2704 char *oid_to_dotstring(const int *oid, char *oidbuf);
2705 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2707 Reverted modifications for ES Update definition for z_IU0Update
2708 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2709 is back to YAZ 2.0.2.
2711 String value attributes for CCL parser.
2713 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2714 which their FirstSearch server returns in Init responses, sometimes
2715 carrying useful diagnostic information when Init fails. This has the
2716 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2717 "z39.50/oclcui.asn", where its definition is somewhat different from
2718 what OCLC document on their web-site, as required to interoperate with
2721 Support for anonymous authentication in yaz-client. Use the command
2724 * Fix the OID of the Index Data-local "admin" Extended Service from
2725 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2726 the 1000, which indicates a locally-defined OID, was a mistake.
2728 --- 2.0.3 2003/06/20
2730 Fix CCL directive @case handling so that it affects string match for
2731 both CCL keywords and qualifiers.
2733 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2734 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2735 Decoder has been updated with ASN.1 changes as listed in
2736 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2737 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2738 z_IUUpdate, remains unchanged.
2740 ZOOM_record_get may now return a record in a specific character set.
2741 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2742 "from" is the character set of record as returned by target. "to" is
2743 the character set to be returned. If omitted, "to" is UTF-8.
2745 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2747 New ODR utility, odr_getelement, which returns name of element for
2748 which encoding/decoding failed.
2750 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2751 in cases where a required element was omitted.
2753 Bug fix: some MARC8 sequences were not converted.
2755 New ZOOM option "step" which specifies number of records to be
2756 retrieved in one chunk. Used in conjunction with "start" and "count".
2758 SRW support for yaz-client. Use scheme http: to use it, e.g.
2761 yaz-client no longer does (un)intelligent character set conversions
2762 by default. Can be enabled with charset and marc_charset commands.
2764 xmalloc trace fix for 64-bit systems such as DEC alpha.
2766 Solaris 2.6 compile fix.
2768 New function, cql_strerror() translates SRW error codes, as returned
2769 by cql_transform_error(), into human-readable English strings. Used
2770 in yaz-client diagnostics when appropriate.
2772 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2773 converts it into a type-1 query which is sent to the server. This
2774 makes CQL available for use with all Z-servers, as opposed to the tiny
2775 minority that can handle CQL queries themselves.
2777 --- 2.0.2 2003/04/28
2779 New Debian package layout similar to the Redhat Package layout.
2781 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2782 and search result respectively.
2784 --- 2.0.1 2003/04/25
2786 Redhat package is now several packages: libyaz (runtime libraries),
2787 libyaz-devel (development and documentation, and yaz (utility programs).
2788 Package spec file by Morten Bogeskov.
2790 New member 'schema' in struct bend_fetch_rr which the name of requested
2791 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2792 handler MAY set this to reflect the schema of the returned record.
2794 New member 'display_term' in struct scan_entry. GFS now sets member entries
2795 and allocates scan entries to be filled by user scan handler. In previous
2796 version, entries member was allocated by the scan handler. That still works,
2797 but the GFS will ignore member display_term - assuming it was NOT set by
2798 the handler. The fact that the GFS now allocates the entries both allows
2799 for new members and makes a scan handler easier to write.
2801 Fix CQL lex buffer overflow.
2803 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2804 SRU default recordPacking is string.
2806 SRU protocol support for frontend server.
2808 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2810 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2812 Added scan for the ZOOM shell (zoomsh).
2816 * String Identifers for Schemas (Amendment 5).
2817 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2818 Old definition for schema
2819 Odr_oid *schema; /* OPT */
2824 Z_InternationalString *uri;
2825 #define Z_Schema_oid 1
2826 #define Z_Schema_uri 2
2829 * resultCount parameter to Sort Response (Amendment 1).
2830 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2832 Support for SRW 1.0 over HTTP. This is an optional feature and
2833 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2836 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2837 on the same port. SRW SearchRetrieveRequests are mapped
2838 to bend_init,bend_search,bend_fetch,bend_close.
2840 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2842 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2843 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2845 ZOOM connections are SRW based if schem http is used for hostname
2846 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2847 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2849 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2850 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2851 distance=n, order=true/false, relation=le, prox unit=word. If
2852 n is omitted, distance 1 is used.
2854 Fixed problem with C compiler include path in wrong order.
2856 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2857 on Solaris. Patch from Ko van der Sloot.
2859 New MARC decode API. All new functions operate on a yaz_marc_t
2860 handle. The most important new functions are: yaz_marc_create,
2861 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2862 decode and destroy respectively. Decoder can produce formats
2863 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2864 include/yaz/marcdisp.h.
2866 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2867 to UTF-8, UCS-32, wchar_t or Latin-1.
2869 * Prototypes for yaz_iconv_-functions moved to separate header
2870 include/yaz/yaz-iconv.h.
2872 Make a few private functions 'static' in unix.c. This prevents
2873 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2875 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2876 are set when Init Response is received.
2878 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2879 but returns diagnostic set as well.
2881 New function yaz_strerror which is a portable wrapper for
2882 strerror/strerror_r/GetLastMessage.
2884 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2885 is returned for MARC. If type is "oai", then OAI MARC is returned.
2887 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2890 --- 1.9.2 2002/11/26
2892 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2894 Fix bad race conditions on SIGTERM and terminate gracefully in
2897 Move retrieval (data1) module to Zebra since nobody seems to be
2900 Add GRS-1 render for ZOOM using same format as yaz-client.
2902 --- 1.9.1 2002/10/05
2904 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2906 Fix broken ESpec handling in data1 module.
2908 SGML reader parses comments and makes them part of the data1 tree.
2910 Added several type casts so that YAZ compiles as C++ code.
2912 ZOOM didn't handle PDU encoding failures properly.
2914 Added more Bib-1 diagnostics (approved extensions).
2916 GNU configure: better check for iconv.
2918 More portable use of accept, getpeername. Check for socklen_t. Use
2919 int/size_t if socklen_t is not defined.
2923 PQF parser rejects bad queries - including those with extra
2924 characters in them. PQF parser used to silently ignore that.
2925 Cleaner API for PQF added, which allows you to get detailed
2926 error information for bad queries (see yaz/pquery.h).
2928 Fixed bug in ZOOM_record_get for type "database".
2930 Implemented mini iconv library supporting conversions between
2931 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2933 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2935 --- 1.8.9 2002/08/20
2937 Fixed ZOOM C record cache so that preferredRecordSyntax and
2938 elementSetName is used to check for already fetched records.
2940 --- 1.8.8 2002/08/02
2942 Added three members in bend_initrequest structure to facilitate
2943 character set negotiation.
2945 Fixed a bug in frontend server that could cause indefinite
2946 loops under rare conditions.
2948 Revised character set utilities (charneg.h) so that encoding
2949 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2951 For PQF, directive @term <type> sets term type for Scan/Search.
2952 Here <type> is general, string, numeric, null. The term type
2953 is inherited - just like @attr.
2955 New call odr_set_charset that sets character set conversion for
2956 international-strings on a ODR stream. Prototype is:
2957 int odr_set_charset(ODR o, const char *to, const char *from);
2958 The InternationalString is still represented as C string in YAZ
2959 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2960 won't). On the protocol level, you can use any encoding.
2962 Support for UNIX sockets in ZOOM.
2964 Solaris recv sometimes returns errno == ENOENT. It is treated as
2965 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2967 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2968 both client and server. Code by Morten Bogeskov.
2970 --- 1.8.7 2002/05/22
2972 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2973 that they can be used directly from Visual Basic. You must recompile
2974 your windows APP if you're using ZOOM.
2976 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2977 Commands "lang" and "charset" sets language and character set respectively.
2978 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2979 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2981 Attributes from multiple CCL fields may be OR'ed rather than merged
2982 using directive "@field or". Fields are still merged by default -
2983 equivalent to "@field merge".
2985 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2988 Fixed bug in zget for parameter ExtendedServicesResponse.
2992 --- 1.8.6 2002/03/25
2994 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2996 Client displays USR.1:SearchResult-1 (hits per term).
2998 Additional Search Info for search in Generic Frontend Server.
3000 Fixed CCL parsing of "field=s".
3002 WIN32 installer - using the excellent NSIS software from nullsoft.
3004 Fixed CCL parsing of "field = - <number>".
3006 Added function yaz_marc_decode that decodes MARC for line mode
3007 display or XML (similar to that used by JZKit).
3009 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3010 Z39.50. But ISO/ILL was, however.
3012 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3013 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3015 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3016 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3018 --- 1.8.5 2002/02/03
3020 New YAZ client features: Command completion and new commands:
3021 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3022 Code provided by Jacob Poulsen.
3024 New call oid_trav, that visits all registered OIDs via callback.
3026 Function ZOOM_record_get now returns const char pointer rather than
3027 void pointer. It saves a lot of type casts.
3029 For YAZ client, command "auth" now allows you to set authentication
3030 in IdPass style. It is enabled when three tokens are given - order
3031 is user, group and password.
3033 Fix memory leaks in MARC record handling for ZOOM.
3035 New option for YAZ client, -k <kilobytes> that sets
3036 maximum record size. Similar to -k option for generic frontend
3037 server and yaz-ztest.
3039 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3041 Prefix query parser reports "fail" when bad attribute set is given.
3043 Fix in MARC decoder. Proximity logging. Fix for attribute set
3044 in scan handler for server. Patches by Shigeru Ishida.
3046 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3049 Configure option --with-openssl=<dir> now works when a directory is
3050 specified. Patch provided by Morten Bogeskov.
3052 New option for YAZ client, -u <auth>, that sets authentication.
3054 ZOOM fix: error information was sometimes "missing", since error
3055 was cleared/reset too when it shouldn't.
3057 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3059 --- 1.8.4 2002/01/04
3061 Scan for ZOOM API. New object ZOOM_scanset. New functions
3062 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3063 ZOOM_scanset_destroy.
3065 New ZOOM function, ZOOM_connection_last_event, that returns type
3066 of last event (such as "receive data", "send data", "apdu received",
3069 New ZOOM option, schema, that specifies schema for retrieval.
3071 New CCL feature. Qualifiers can be aliases for one or more
3072 other qualifiers (if more than one is given, OR is used).
3074 ZOOM uses named result sets if target supports it.
3076 Two new YAZ client commands: . (dot, which sources a script of YAZ
3077 client commands), and ! (to execute shell command.). Implemented
3080 Working on Debian packages.
3082 --- 1.8.3 2001/11/19
3084 YAZ client enables named result sets only if target supports it.
3086 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3088 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3089 with key="host" to get same result.
3091 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3092 Function Z3950_resultset_record(s) returns references to records
3093 "owned" by resultset. To become owner use Z3950_record_clone.
3095 Function z_ext_record handles Extended Services. Thanks to
3098 --- 1.8.2 2001/11/12
3100 CCL Parser fix: ignore token comma when dealing with and-lists.
3102 Documentation updates for COMSTACK.
3104 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3105 Changed prototype Z3950_records. For some functions, int parameters
3106 were changed to size_t.
3108 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3111 New MARC decode/display function, marc_display_exl, which properly rejects
3112 non-ISO2709 records. YAZ client uses it.
3114 --- 1.8.1 2001/10/29
3116 Fix bug: local attribute set wasn't set correctly in PQF strings.
3120 * Old Z39.50 codecs no longer supported.
3122 Added ZOOM C binding. See http://zoom.z3950.org/
3124 Renamed states for COMSTACKs to avoid confusion with events.
3126 Implemented cs_look and proper cs_rcvconnect.
3128 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3130 Configure detects POSIX threads on OpenBSD.
3132 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3133 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3135 When error is returned from present handler, non-surrogate diagnostic
3136 is returned in present response (and fetch handler is no longer called).
3138 * Minor adjustments to pquery parser (PQF). Token characters may be
3139 escaped by using backslash (C-style).
3141 PQF parser allows string attribute values to be specified. For @attr,
3142 non-numeric characters after the equal-sign are treated as strings
3143 (e.g. @attr 9=title).
3145 CCL trunction character may be defined (@truncation in file)
3147 * function zget_ExtendedServicesRequest sets waitAction to
3148 waitIfPossible (was wait).
3150 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3153 CCL operator names may be set in field definition files (CCL_bibset).
3154 See ccl/bib1 for an example.
3156 Fixes in ASN.1 compiler for C++ compatibility.
3158 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3159 and "op_or" to avoid conflict with C++.
3161 Fixed problem with GNU readline detection on Redhat 7.0.
3163 Added step-size for Scan backend handler.
3165 Fixed bug that made the frontend server crash when no attribute
3166 set was specified for scan.
3168 Front-end server automatically switches to original working directory
3169 when installed as an NT service. Previously -w had to be specified to
3172 Added extended attributes for retrieval module (data1), so that data1
3173 records carry d1_readXML/SGML attributes. d1_read also supports
3174 null-data rules ( <tag/>)
3176 On UNIX when POSIX threads are available, a separate library libyazthread
3177 is created. Programmers should link with that library and the yaz library
3178 when using threads. The reason for the split was that some applications
3179 on Linux, such as Apache, doesn't work well when using shared objects that
3182 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3183 (or any frontend server) in SSL mode by specifying ssl: followed by
3184 address. Only tested on UNIX.
3186 Added feature for CCL module. Virtual structure s=al or s=ol generates
3187 and-list and or-list respectively instead of phrase search.
3191 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3192 log_mask_str. This was done to avoid name conflicts with other libraries
3193 (such as other PHP extensions).
3195 Added raw OID member for preferred record syntax (request_format_raw)
3196 and returned record syntax (output_format_raw) for backend fetch method.
3198 Config file yaz-config now accepts options so that it returns specific
3199 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3201 Shared library support for UNIX using GNU libtool.
3203 * Modified backend interface. Request/Response struct's replaced by
3204 one read/write C struct. For example bend_fetchrequest and
3205 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3206 Every handler - even search has to be registered in bend_init
3207 handler. This means that the YAZ library no longer refers to
3208 external functions and it makes it possible to make the whole
3209 thing a single DLL/SO.
3211 Added Segment handler for backend server.
3213 Added Zmbol/Zebra administrative functions to YAZ client.
3215 Threaded frontend server on UNIX (when POSIX Threads are available).
3216 Starting the server with option -T enables multi-threading.
3220 Added configure option --enable-comp/disable-comp to control use
3221 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3222 located in sub directory asn.
3224 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3225 in ${exec_prefix}/bin along with the other programs yaz-client and
3228 GNU automake used to maintain makefiles.
3230 Added several OID's.
3232 Changed retrieval module so that we can load records with no abstract
3233 syntax defined. Tagpaths in these records are fully composed of string
3236 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3240 On UNIX, the generated makefile now supports a proper 'make install'.
3241 The prefix can be set via GNU configure to set the install location
3242 (default is /usr/local).
3244 * YAZ programs client and ztest were renamed to yaz-client and
3245 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3246 locations, such as /usr/bin,/usr/local/bin,etc.
3248 * YAZ Header files were moved from include to include/yaz. YAZ Header
3249 files are referred to as include <yaz/log.h> rather than <log.h>.
3250 The YAZ include path (-I ..) is therefore the same as before. Programmers
3251 should update their #include statements or use -Ipath/include/yaz
3252 instead. The main motivation for doing this change is that YAZ header files
3253 can be installed in "standard" locations /usr/include,/usr/local/include
3254 without introducing conflicts, since ALL YAZ header files are stored
3255 in subdirectory yaz (under /usr/include for example).
3257 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3258 rather than project/workspace files. We switched because project files
3259 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3262 Changed name of logging function, logf, to yaz_log, to prevent name
3263 clash with some math-log functions. The YAZ header log.h defines logf
3264 to yaz_log (#define) so there should be no incompatibilities by this
3267 Added bend_start/bend_stop handlers for server. These handler are
3268 called on start/stop of server. For windows they are called whenever
3269 a service is started/stopped.
3271 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3272 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3273 in util/yc.tcl. The auto-generated C code structures are, in a few
3274 cases, incompatible with the old decoders. There are differences in the
3275 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3276 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3277 The preprocessor variable ASN_COMPILED is defined when the compiled
3278 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3279 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3280 wish to use the old encoders/decoders you can specify --disable-yc
3283 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3284 version so that it supports both new - and old version of DB Update
3286 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3287 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3288 change. The name parameter can be set to 0 in which no name is specified
3289 for the construction. The macros odr_implicit and odr_explicit sets name
3290 parameter to zero for the construction involved. New macros
3291 odr_implicit_tag and odr_explicit_tag are similar to the others,
3292 except that a name parameter is added. For programmers' that don't use
3293 ODR they probably only need to change the call to z_APDU and z_External.
3295 Added access control facility by interfacing the TCP wrapper library.
3296 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3297 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3298 name of the daemon and enables the access control as specified in
3299 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3301 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3302 den Dool <H.M.vdnDool@kub.nl>.
3304 Added reference ID parameter to most functions in server API - refer
3305 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3307 Changed name of ccl library to libccl.a (was ccl.a).
3309 Fixed bug in decoder for Explain (Category TargetInfo).
3311 Added support for GNU readline in client. Thanks to Jacob Poulsen
3312 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3314 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3315 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3316 IMPLEMENTATION! This change was made to the development version before
3317 the ZIG decided to retract the amendment. If any users MUST be
3318 compatible with the original Update definition, PLEASE CONTACT US, and
3319 we will include a separate definition corresponding to the old Update
3320 ES. Note that because of the change to the ASN.1 of the
3321 TaskPackageRecordStructure we cannot define a single structure that
3322 will support both versions.
3324 * Added const modifier to buffer parameter for some ODR/BER encoding
3325 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3326 completeWAIS, odr_dumpBER.
3328 Fixed bug in client.c which caused a crash when a scanResponse didn't
3329 contain positionOfTerm.
3331 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3332 * will cause an error in a client if a non-YAZ target sends both a
3333 * list of Scan entries and non-surrogate diagnostics.
3335 Retrieval module enhancements. Tag sets may be typed in the reference
3336 to it. From the .abs-file the "tagset" directive takes a third optional
3337 integer type for the tag set referenced. From a .tag-file the "include"
3338 directive takes a third optional type as well. The old "type" directive
3339 in the tag set itself is still recognized but acts as the default type
3342 Backend interface change. Individual Scan terms returned from bend_scan
3343 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3344 in include/backend.h.
3346 Retrieval module enhancements. Multiple tag sets and attribute sets may
3347 be specified in abstract syntax specs. Revised the error/warning for
3348 logging messages reported by the retrieval module when reading the
3351 Object Identifier system (oid_..) changed. The API is backwards
3352 compatible but the oid-routines now allocates new OID's when needed.
3353 Raw OID's may be specified in oid_getvalbyname.
3355 YAZ now uses GNU configure to generate Makefile(s).
3357 * Minor changes in some of the member names of DeleteResultSetRequest and
3358 DeleteResultSetResponse. See include/proto.h.
3360 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3361 and added member 'languages' in TargetInfo (which was missing).
3363 Changed the way attribute sets are handled in the retrieval
3364 module. These are now cached, just like the abstract syntaxes
3367 Changed YAZ so that it links with compiled ASN.1.
3369 Added Explain-schema definitions and mapping routines. The following
3370 Explain categories have been implemented: AttributeDetails,
3371 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3373 Fixed minor bug in Windows version of Server Library.
3375 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3377 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3379 Added EXTERNAL: UNIverse Resource Report (non-standard).
3381 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3382 ENUMERATED and SET OF.
3384 * Added 'const' to some of the char pointer arguments for the
3385 functions, data1_read_node, data1_getelementbytagname,
3386 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3389 Fixed bug in data1_insert_taggeddata - the last_child member of
3390 parent wasn't initialised.
3392 * Changed data1_read_record and data1_read_node so that the supplied
3393 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3394 doesn't refer to any parts of the "SGML"-buffer.
3396 Fixed bug in server library (Windows version of statserv_remove).
3398 * Changed code so that it compiles as C++. The type definition
3399 of Odr_fun which is a member of Odr_arm was changed. The result is,
3400 that an explicit typecast is needed for the fun pointer when
3401 using Odr_arm - as in:
3402 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3404 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3406 Implemented the new structured date and time definition as approved
3407 by the ZIG. Added schemaId element to the specificTag in Espec-1
3408 (also approved at the last ZIG). Thanks to RVDM.
3410 Added some Object identifiers (RVDM).
3412 Changed the Update Extended Service (RVDM).
3414 Added command "refid" to client which specifies referenceId for
3415 the following requests.
3417 Implemented extended service handling for server. See ztest.c
3418 for an example as well as backend.h. New handlers are registerd
3419 in the Init handler.
3421 * Changed interface for sort in server.
3423 Added new members to statserv_options_block. It allows a server
3424 to read options from another source than just the command line. Thanks
3425 to Charles Woodfield.
3427 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3428 renamed to zboolean. Some C++ compilers complained about the name.
3430 Minor changes to gils.abs. Added index 's' (sort) on title
3431 and date/time-last-modified.
3433 --- 1.4pl2 1998/1/30
3435 Fixed bug in server library regarding inetd mode (-i). This bug
3436 was introduced by release 1.4.
3438 --- 1.4pl1 1998/1/29
3440 Added sort facility in client and backend server interface.
3442 Fixed problem with dependencies in Makefile(s).
3444 Fixed bugs for encoders/decoders of extended services and
3447 Implemented sub-tree feature for schemas. Sub-trees are
3448 referenced in *.abs-files. See explain.abs for an example
3449 of the use of this feature.
3451 Modified bib1.att; local attributes for ANY didn't include
3452 ANY itself (only affects use of the retrieval module).
3454 Fixed bug in plain SGML reader in function data1_read_node:
3455 tags with prefix "var" was incorrectly interpreted as variants.
3457 Added feature "sub-schemas" to enable references to - and definitions
3458 of - group of elements.
3460 * Removed member parent from type data1_element (in data1.h).
3462 Implemented function odr_nullval() that returns the value of
3465 * Removed member num_children from data1_node (in data1.h).
3467 Made NT service interface part of the server library. The
3468 function statserv_main uses the NT service when required and
3469 calls the statserv_start / statserv_close routines.
3471 Routine zget_SearchRequest and zget_PresentRequest fills
3472 resultSetName/Id member with "default" instead of "Default".
3474 Fixed memory leak in server. Request queue member wasn't freed.
3476 Fixed nmem_exit so that memory is freed.
3480 Revised the CCL parser utility to be thread safe.
3482 Added function, oid_ent_to_oid, to replace the function
3483 oid_getoidbyent, which is not thread safe.
3485 * Added nmem_init and nmem_exit to initialize and release
3486 NMEM resources. Function nmem_init should be called once in the
3487 initial thread before NMEM/ODR is used. statserv.c and client.c
3488 have been changed accordingly. The change was necessary to make
3489 NMEM thread safe. The NMEM memory pool is shared amongst threads
3490 in a process. Unix-based applications will still work fine without
3493 Added NT Services interface for the the Z39.50 (statserv) Server.
3494 Refer to the ztest.c source on the usage.
3496 Windows 95/NT port using MSVC5.0. Project files are included in the
3499 * Defined new 'global' handle for the retrieval (data1) system. The
3500 new handled, data1_handle, describes the state of the data1 system.
3501 This handle is passed as first argument to virtually all
3502 data1 related routines. The functions data1_create and data1_destroy
3503 creates and destroys a data1 handle respectively.
3505 Added ODR encode stream member to all backend request structures
3506 init, search, scan etc. This stream should be used to allocate all
3507 memory used for the response when thread safe operation is needed.
3509 Changed the comstack utility, cs_addstr, to be thread safe. The
3510 returned hostname string returned by the function is now part the
3513 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3514 function. The cs_straddr takes a COMSTACK handle as argument, so this
3515 function must be used after cs_create and before bind/connect.
3516 This function is thread safe.
3518 Moved test server to 'ztest' directory - generic server code still
3519 in 'server' directory.
3521 Made prefix query (pquery.c) utility thread safe.
3523 Added new function modifier YAZ_EXPORT to 'export' public DLL
3524 functions when using windows (see include/yconfig.h).
3526 Added definitions to the OID database (util/oid.c) (RVDM).
3528 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3530 Added call to ccl_rpn_delete in client program.
3532 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3533 release of RPN structure.
3535 Added support for C++, headers uses extern "C" for public definitions.
3536 With input from RVDM.
3538 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3539 Thanks to Ronald van der Meer (RVDM).
3541 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3543 Added support for private extensions to the OID database
3544 (oid_setprivateoids()). Thanks to RVDM.
3546 Added optional, physical ANY (key replication)
3548 Fixed null-reference problem in GRS-1 output filter.
3550 Proximity operator added to Prefix Query Format (PQF).
3552 In test client command "base" accepts multiple databases.
3554 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3558 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3560 Smallish bug-fixes in the new encoders/decoders (explain).
3562 Bug fixed in DeleteRequest.
3564 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3566 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3568 Added SOIF syntax (using private OID for now) to retrieval module and client.
3570 Added Update extended service.
3572 Added SearchResult-1 additional info structure.
3574 Added optional CCL (ISO8777) interpreter as separate module. Available
3577 --- 1.2 1996/6/10 (1st anniversary release)
3579 Added Summary record syntax. Lightly tested.
3581 Added OPAC record syntax. Untested.
3583 Added ResourceReport service encoders/decoders. Untested.
3585 Fixed bug in z_Unit - wrong tagging on unitSystem.
3587 Fixed bug in the DiagRecs decoder.
3589 Added options for max PDU size and session timeout to frontend-server.
3591 Added documentation of query-language parsers and other supporting utilities.
3593 [frontend-server] Added Attribute set to the bend_scanrequest API.
3595 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3596 surrogate diagnostics were generated.
3598 [retrieval] Allow multiple local values for attribute.
3600 [retrieval] Allow multiple attributes per element in .abs files. index type.
3602 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3604 --- 1.1pl2 1996/4/10
3606 Minor changes, mostly specific to Zebra's requirements (retrieval)
3610 Repaired bug in frontend server when running multiple listening
3611 endpoints in dynamic mode.
3613 z_External() now won't break if a known, ASN.1 value comes encapsulated
3614 in an octet-string. The value will pass through unmodified in an Odr_oct.
3616 Added a bit of code to the demo client to decode & display
3617 ASN.1-structured records represented in the octet-aligned branch of
3618 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3620 Added z_ext_getentbyref() to the ASN module. Doc updated.
3622 * Completed the SCAN definition in the ASN module. This may break SCAN
3623 code based on older YAZ-versions at compile-time. The fix is easy -
3626 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3627 under the SCAN definition. Remember to initialize this, server-people.
3629 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3630 that this does not extend to ODR and ASN.
3632 Comstack allows insertion of established socket (primarily for
3633 inetd-operation of servers). Doc updated.
3635 Front-end server can now start from the inetd in TCP mode. Doc
3638 --- 1.0pl4 1996/1/24
3642 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3643 the rank and record number.
3645 Adjustments to the frontend server.
3647 Fixed diagnostic BER dumper. It ignored the file argument.
3651 Various changes to retrieval module.
3653 Changed the union discriminators of the protocol files from enums to
3654 ints paired with #defines.
3656 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3659 *Changed operator in the RPN structure to 'roperator', again to avoid a
3662 Fixed problems in Explain decoders/encoders.
3664 --- 1.0pl2 1995/12/6
3666 Memory bug in log module fixed.
3668 --- 1.0pl1 1995/12/5
3670 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3672 Bug in Explain DatabaseInfo module fixed.
3674 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3678 The shift to v1.0 signals that we now consider the *core* functionality
3679 of YAZ reasonably stable (the core being more or less equivalent to
3680 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3681 tested (Explain not at all - though that will happen soonish).
3683 Minor changes to code to support Windows port.
3685 Various minor changes after we're getting to use GRS-1 & co. more.
3687 Added Espec-1 format.
3689 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3690 of the protocol and it cannot be selected when encoding (maps into 'string'
3691 when decoding). Needed to talk to some servers.
3693 Demo client can request simple element set names.
3695 Added Diagnostic Format encoders/decoders.
3697 Added simple Close handling to frontend server (no hooks for resource
3698 reporting yet), and demonstration client.
3700 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3702 --- 1.0b3 1995/08/24
3704 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3705 handled incorrectly when records were requested in the searchResponse. This
3706 will only affect you if you use the frontend-server.
3708 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3709 Test-client will ask for and print GRS1. Ztest will return dummy records
3712 Added Explain encoders/decoders to the service-level API. Untested.
3714 Added Extended Services: Item Order encoders and decoders to the Service-
3715 level API. Untested. We could use a recent copy of the pertinent bits
3716 of the ILL protocol to add those bits.
3718 Added diagnostic format 1 encoders/decoders to the service-level API.
3721 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3722 odr_cons.c, which causes a more correct output.
3724 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3725 was always set to 0 when no records were requested in the searchRequest.
3727 * Added better external-handling. This shouldn't harm old code that
3728 *encodes* externals. It can break code that looks for a
3729 'single-ASN1-type' representation, since those types that are known
3730 are now decoded immediately. Look at the SUTRS sample code in
3731 seshigh.c and client.c. Documentation updated.
3733 Handling of structured records in bend_fetchresponse. Length -1 marks
3734 structured record, type is deduced from format field.
3736 --- 1.0b2 1995/06/27
3737 Fairly quick maintenance release to add SUTRS support.
3739 Fixed handling of SUTRS records in the demonstration client.
3741 * Added format field to the bend_fetchrequest and bend_fetchresponce
3742 structures of the backend API (frontend server). When the record is
3743 returned, the value of the format field is mapped to an OID. The
3744 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3745 of the record. The special value VAL_NONE in the bend_request means
3746 that no specific format was requested by the client. Documentation
3747 updated accordingly. Test server (ztest) will return a fixed dummy
3748 SUTRS record if your client requests SUTRS.
3750 Documentation updated accordingly.
3752 You can now set external libraries and RANLIB support in the top-level
3756 First public release.
