1 yaz-ztest returns schema for MARCXML test records. SRU require that
2 recordSchema for records.
4 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
5 instead of non-surrogate diagnostic. This is a per-record failure.
7 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
8 may refer to multiple listeners now. Attribute listenref is a comma separated
11 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
12 option is given for GFS, the dirname of filename (for -f) is used
13 as prefix for options such as cql2rpn, ccl2rpn, etc.
15 Content-Type charset fixes YAZ-701 . Do not inspect charset in
16 Content-Type header for SOAP when decoding SRU. The payload (XML)
17 itself tells what encoding it is. In response, never supply encoding
18 in Content-Type. The response payload (XML) tells what it is (with no
19 encoding in XML it's UTF-8).
21 HTTP decoding: allow blanks in URL paths YAZ-700
25 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
26 and facets. Ensure recordData and recordSchema are always present in
27 record element, because they are required.
29 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
32 Simplify in a lot of places using odr_strdupn.
34 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
38 Increase various buffers in GFS's statserv_options_block
39 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
40 This change makes many type-casts redundant, and, thus simplifies code.
42 Remove last bits of WAIS support.
44 Remove member 'size' from Odr_oct.
46 Slim down the public part of 'struct odr'. Most elements are not part
47 of struct Odr_private.
49 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
50 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
51 In particular facets are supported in both client - and server side.
52 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
53 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
54 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
55 both request/response). This is what a search handler in the GFS
56 will see (regardless of whether operating in SRU mode or Z39.50).
58 Changes to the srw.h (SRU/Solr) definitions include:
59 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
60 (char*), which replace union query and query_type (int). This is because
61 SRU 2.0 supports a queryType parameter. This also means that, to carry
62 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
63 x-pquery=PQFstring (extention parameter). The extension parameter
65 - New element, packing, that has information about SRU
66 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
68 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
70 New element, packing, in Z_SRW_explainRequest.
72 New elements in Z_SRW_scanRequest, queryType and scanClause.
73 These replace query_type and scanClase untion. This is similar to what
78 GFS: log when closing down - at least SIGTERM YAZ-684
79 Also change formatting WRT PID logging a bit.
81 Improve display of MARC records with multi-byte subfield IDs YAZ-695
82 In some rare cases subfield identifiers are multi-byte characters.
83 This will try to deterime length of those and split accordingly.
84 This affects display in line mode as MARCXML/MarcXchange. The encoding
85 of ISO2709 is the same.
87 Change inp argument to const for yaz_read_UTF8_char.
89 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
91 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
93 Better check of marc leader info YAZ-691
94 Problem is that some systems generate MARCXML/MarcXchange with
95 funny headers. These will not work if encoded as ISO2709.
96 Some tests produce new output, due to updated warning messages
98 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
100 yaz-client: display MAB records YAZ-689.
101 Thanks for Heiko Jansen for this patch.
103 New utility z_get_HTTP_Response_server which allows both HTTP server name
104 and HTTP server URL to be given in response.
106 Debian: do not depend on obs tcl8.3.
108 Debian: do not depend on obs libicu36-dev.
110 --- 4.2.68 2013/09/23
112 GFS: pass additionalSearchInfo to search memeber search_input if
113 given. Otherwise pass otherInfo. Request for facets and other search
114 related things will be passed there in future versions of YAZ.
116 New ZOOM setting, authenticationMode, which allows authentication
117 paramters to be encoded in the URL rather than via HTTP Basic auth.
120 rpn2solr: fix nested AND/OR handling. YAZ-685
122 Add comparison routines for some Z-types, such as NamePlusRecord,
123 RPNQuery, Query, RecordComposition and OtherInformation.
125 --- 4.2.67 2013/09/19
127 Don't decode MAB as MARC. Just like we don't attempt to decode
128 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
130 CCL: allow quoted terms for date ranges. YAZ-681
132 Introduce ccl_parser_qual_search. This function makes old function
133 ccl_qual_search, from YAZ 2, available again.
135 Add yaz_facet_list_to_wrbuf. YAZ-683
137 --- 4.2.66 2013/09/11
139 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
140 schema was given for search. YAZ-675
142 Add Solr date range searches. YAZ-621
144 --- 4.2.65 2013/08/22
146 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
148 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
150 ISO2709/MARC parse most octet aligned records; not just those that
151 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
152 MARC parse more records instead of just dumping as is. YAZ-670
154 ZOOM: proper caching for variations of record schema. YAZ-671
156 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
158 --- 4.2.63 2013/07/17
162 --- 4.2.62 2013/07/11
164 New utility z_get_HTTP_Response_details - an extended version of
167 New utility yaz_url_get_error which returns error message of last
168 failed yaz_url_exec call.
170 yaz-url and url functions: allow max HTTP redirects to be controlled.
172 New functions yaz_file_glob2, yaz_xml_include_glob.
173 These functions takes a flags parameter, which, for now only controls
174 whether to fail inclusion of a non-existing file (without glob
175 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
177 --- 4.2.61 2013/06/20
179 For MARC XML parsing, allow record without leader. A fake/default leader
180 is inserted and a warning is tagged with the record.
182 ICU: fix leak in in icu_iter_get_org_info.
184 --- 4.2.60 2013/06/14
186 ICU: fix bug in icu_iter_get_org_info (un-init variable).
188 --- 4.2.59 2013/06/11
190 Implement z_HTTP_header_remove.
192 --- 4.2.58 2013/06/11
194 ICU: Disallow 0 ptrs for some ICU string utilities.
196 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
197 returns original tokens (before normalization).
199 CCL: avoid z39.58/regex truncation when not needed. Apply only the
200 conversion of those masks, when absolutely necessary.
202 CCL: configurable masking character - @mask. Default masking character
205 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
206 full response anyway, so a Transfer-Encoding header will obstruct the
209 --- 4.2.57 2013/05/15
211 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
212 picking a socket. Problem is that some systems has IPV6 support, but
213 we can't create sockets for them, so we pick AF_UNSPEC first.
215 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
216 use content_len to determine resulting Content-Length in HTTP response
217 and NOT Content-Length supplied in headers by user.
219 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
220 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
222 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
225 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
226 with big endian and unsigned char (by default).
228 --- 4.2.56 2013/04/26
230 Fix yaz-client connect (crash in 4.2.55).
232 --- 4.2.55 2013/04/26
234 Fix proxy/host problem for ZOOM that could occur if unix sockets
237 New Debian package libyaz4-dbg.
239 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
240 differently in tcpip_close.
242 --- 4.2.54 2013/04/17
244 Windows installer of YAZ includes YAZ4J as a component.
246 CQL: allow "extra terms" again, by default. Thus, the CQL parser
247 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
248 and earlier. CQL parser may operate in strict mode where queries
249 not conforming to the standard BNF are rejected (syntax error).
250 Whether the CQL parser operates in strict mode is controlled with
251 cql_parser_strict . Strict mode enabled with option -S for utilities
252 cql2pqf and cql2xcql .
254 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
256 --- 4.2.53 2013/04/10
258 New charset, MARC-8c, which is like MARC-8 but allows control characters
259 0x01 through 0x1F, except ESC to be passed through verbatim.
261 Fix a problem with duplicate sub field character in MARC output. Problem
262 happened only when output was MARC-8 encoded.
264 --- 4.2.52 2013/04/03
266 yaz-ztest: Use hash for fake hit count. Before, random number was used.
267 This is problematic for unit tests using yaz-ztest. This patch also makes
268 a hash for CQL queries. For RPN, any term with a leading digit will be
269 treated as pseudu hit count (to force any particular hit count by a client).
271 yaz-ztest: return unique MARC dummy records. Beyond record offset
272 24, the author surname is patched with offset to make all records
275 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
276 on system wide default (/proc/sys/net/ipv6/bindv6only).
277 @4 binds to IPV4 only. @6 binds to IPV6 only.
279 Update CQL API documentation a bit
281 CQL: don't accept extra terms for queries. Makes the CQL parser
282 stricly conformant to the standard.
284 --- 4.2.51 2013/02/12
286 GFS: scan handler gets extra_args from request and may return extra
287 response data . That's for SRU only.
289 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
291 --- 4.2.50 2013/01/30
293 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
295 OPACXML: sync spelling of availabilityDate in XML to that of Schema
296 opaxxml.xsd. The schema had the correct spelling of this member always.
297 The ASN.1 was mis-spelled and still is (API change) - we are
298 not changing this. However, the OPAC to XML conversion had yet
301 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
304 New function, z_ext_record_oid_nmem, which is similar to
305 z_ext_record_oid but takes NMEM rather than ODR
307 --- 4.2.49 2013/01/18
309 ICU: New conversion element 'join' which joins tokens into one
310 with a custom character given by rule attribute.
312 --- 4.2.48 2013/01/10
314 New GFS search member: present_number. This is a hint to the
315 search handler how many records are going to be fetched immediately
316 following search. There's no guarantee that it's going to be the case,
317 since it depends on hit count (for Z39.50 piggyback) and whether errors
320 Make a few functions static (private). The functions getbyte_stream,
321 ungetbyte_stream and yaz_gets are now private. They were never declared
324 yaz-marcdump: exit(5) for serious decoding errors
326 ISO2709 decoding: be more picky WRT header
328 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
329 was only used as to indicate that next-result-set-position should be
331 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
332 Based on patch from Ashley Sanders.
334 Make some functions static/private in PQF parsing. Those functions were
335 never declared in a public header and so should not be in use by
336 applications based on YAZ.
338 --- 4.2.47 2012/11/23
340 ZOOM: special options to control APDU logging.
341 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
342 logging of APDUs until "saveAPDU" option is set again. If logging is
343 already enabled the effect is that current APDU buffer is cleared.
344 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
345 logging (default behavior on new connection).
346 The APDUs sent/received can be obtained by using
347 Using ZOOM_connection_option_get(c, "APDU") or
348 ZOOM_connection_option_getl(c, "APDU", &l).
350 GFS: relay implementation_version from backend
351 From 3.0.40 and later, implementation_version from backend was
352 not used in init response at all.
354 --- 4.2.46 2012/11/15
356 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
357 mode at all. Probably never did.
359 Make a new version of ztest.pem that, at least, is not expired.
361 --- 4.2.45 2012/11/13
363 Fix description of CCL directive 'case'.
365 More tight checking of form arguments (yaz_uri_to_array). Makes
366 YAZ better at rejecting big and/or bad POSTs.
368 SRU decoding does not report more than up to 10 invalid arguments.
370 rpn2cql: less quotes in generated terms. Semantics unchanged, but
371 it's prettier this way.
373 --- 4.2.44 2012/10/25
375 New utility yaz_decode_init_diag. Defined in proto.h.
377 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
378 given for unix local socket.
379 The COMSTACK string for doing so is:
382 unix:/myfile:tcp:localhost:9999/mybase
383 unix:/myfile:localhost:9999/mybase
384 unix:/myfile:http://fakehost/mybase
386 debian: Use dpkg-buildflags in build process.
388 --- 4.2.43 2012/10/19
390 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
391 global's SRU service uses a recordPosition scheme starting from zero.
392 First record's position should be one
393 according to the standard.
395 --- 4.2.42 2012/10/18
397 Allow more namespaces for SRU. This is to allow, for example, an
398 incorrect namespace returned from server
399 http://services.igi-global.com/sru .
401 Minor fixes for compilation on Windows.
403 --- 4.2.41 2012/10/11
405 daemon: log total number of bad signals from child on stop so that it
406 is more easy to spot problems with child worker processes.
408 retrieval: empty backend name attribute omits element set
409 from being used in retrieval.
411 --- 4.2.40 2012/10/04
413 Implement Solr sort strategy "solr", similar to sru11 sorting.
414 This will implement the correct parameters on Solr requst to do
417 --- 4.2.39 2012/09/28
419 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
422 MARC: Extra/missing indicator handled for MARCXML.
423 The indicator length is given in header and is the same for the
424 whole record. If attributes ind1, ind2 are missing, then content
425 character defaults to blank. Extra indicator attributes (beyond)
426 indicator length are treated as an error.
428 Reformat: delete trailing whitespace
430 --- 4.2.38 2012/09/17
432 MARC: fix non-ASCII characters for leader. This is to ensure we can
433 generate XML in UTF-8.
435 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
436 in one node with structure word.
438 --- 4.2.37 2012/09/04
440 yaz-json-parse: JSON output may be pretty printed by using option
443 Increase default value of max message for Z39.50 Init for GFS, ZOOM
444 and yaz-client. Old value was 1 MB. New value is 64 MB.
446 --- 4.2.36 2012/08/22
448 yaz-client: don't display bogus records from SRU servers. Some SRU servers
449 return more records than given by *maximumRecords*. Skipping those in
452 record_render: simplify buffer return handling and fix at least one bad
453 memory reference, that broke the test_embed_record sometimes.
455 Allow http://user:pass@host notation for yaz_url_exec.
457 zoomsh: allow shell command to be executed. Via the system(3) call.
459 yaz_poll: Allow num_fds == 0
461 yaz-client: fix bad encoding of "itemorder item". The itemorder
462 item <no> - command forgot to use length of encoded Item Request
463 package. Error present since YAZ 3.
465 yaz-ztest: fix bad usage of session handle. Bug was introduced when
466 result sets were saved (271a9c83).
468 SRU recordPacking: guess record packing in response rather than looking
469 at the recordPacking element which, OF COURSE, changed semantics in SRU
472 Decode SRU 2.0 responses. The official namespace for responses, according
473 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
474 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
475 nature.com's server, however, usee namespace
476 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
477 we are now using a glob-expr to match up the namespace. ZOOM C and
478 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
479 I can not find a single real example showing the "real" namespace in
480 the documentation from OASIS. The namespace for requests is different
481 from responses, but this is not added to YAZ yet, when we don't encode
484 --- 4.2.35 2012/06/26
486 zoom/record_render: add support for Base64 decoding fo MARC records
487 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
488 which will decode base64 + ISO2709 marc-8 encoded material from text node
491 --- 4.2.34 2012/06/07
493 Add missing definitions ZOOM_resultset_get_facet_field_by_index
494 and ZOOM_resultset_facets_names.
496 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
499 Change APDU dump printing to avoid long leading blanks. For levels 16
500 or larger the level is shown and the indentation is truncated but
501 recursed with modula 8. This makes it still reasonable easy to read
502 - even for nested BER dumps.
504 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
505 return 0 (incomplete package) in case where the BER package was
506 considered too nested (return value of -2).
508 dumpber: lines of level 15 are not indented further. Two spaces per
509 indentation; indentation 15 or more is indented to a fixed indentation
510 and augmented with a level=<no> indication.
512 zoomsh: increase max size of command+args
514 GFS: No limit in RPN buf size in CQL to RPN conversion.
516 --- 4.2.33 2012/05/09
518 New function for daemon utility, yaz_daemon_stop .
520 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
522 --- 4.2.32 2012/04/25
524 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
525 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
527 --- 4.2.31 2012/04/23
529 YAZ daemon utility relays SIGUSR1 to child process.
531 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
532 would result in en empty database list - which in turn would result in
533 encoding failure for search.
535 Fix reading beyond string in yaz_sort_spec.
537 --- 4.2.30 2012/04/11
539 Add two new SRU diagnostics:
540 236: Access to specified database denied
541 1015: Init/AC: Maximum number of simultaneous sessions for Userid
543 Document the very useful ZOOM-C option "apdulog".
545 CQL to RPN: term may be passed through verbatim. This is enabled with
546 truncation.cql . The assumption being that the term is already CQL.
548 --- 4.2.29 2012/03/20
550 record_conv: leader spec may be given for marc element.
551 The leader spec is given as attribute leaderspec for element marc.
552 For example to convert a MARC21 record from MARC-8 to UTF-8:
553 <marc inputformat="marc" outputformat="marc"
554 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
556 record_conv: allow user-XSLT params. For example:
557 <xslt stylesheet="MARC21slim2DC.xsl">
558 <param name="myparameter" value="myvalue"/>
559 <param name="otherparameter" value="othervalue"/>
562 record_conv: fix error handling for missing marc charsets.
564 CQL: fix extra terms in wrong order.
566 --- 4.2.28 2012/03/06
568 record_conv: modify new API for conversion types. The conversion types
569 may be passed in new functions yaz_record_conv_configure_t and
570 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
572 Avoid mixed statement/variable declare; fixes compilation with Visual
575 --- 4.2.27 2012/02/28
577 Add non-standard SRU diagnostic: 235: "Database does not exist".
578 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
579 Update SRU to Bib-1 diagnostic maps accordingly.
581 CCL: add two new diagnostics for unsupported masking. The new
582 diagnostics are: "Embedded truncation not supported" and
583 "Single charcacter mask not supported".
585 --- 4.2.26 2012/02/23
587 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
589 --- 4.2.25 2012/01/11
591 Build YAZ for Ubuntu Oneiric.
593 CCL: allow parantheses for proximity operands. For example CCL query
594 (a) % (b) is now allowed.
596 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
597 marked dead, rather then being destroyed. If not, the session memory is
598 being free'd before the search/scan handler is finished. Also destroy
599 'request' memory in request_release rather than in various places,
600 which resulted in leaks from time to time.
602 --- 4.2.24 2011/12/21
604 cql_sortby_to_sortkeys: honor sort prefix.
606 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
607 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
608 The rpn2cql family of functions now always returns quoted CQL terms.
610 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
612 --- 4.2.23 2011/12/15
614 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
615 sequence is treated as one. For example, &&a=b&&&c& is identical to
618 --- 4.2.22 2011/12/05
620 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
621 APDUs for a connection to a WRBUF.
623 --- 4.2.21 2011/11/23
625 Fix cql_sortby_to_sortkeys. Completely broken before.
627 Make CCL's @truncation work again.
629 --- 4.2.20 2011/11/09
631 New ZOOM connection setting: tproxy. It's like proxy, but does not
632 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
633 to set resolved address + port for a connection outside ZOOM itself.
635 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
637 --- 4.2.19 2011/11/07
639 Fix uninitialized variable in Solr spell support (could cause SEGV
640 for SRU response decoding).
642 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
643 back-end's addinfo through into the ZOOM response addinfo.
645 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
646 they are separated by a colon and a space rather than simply
649 --- 4.2.18 2011/10/28
651 Add support for Solr spell-checking/suggestions through ZOOM.
652 If a Solr target has been configured correctly for spelling-checking
653 and suggestions, these will now be returned on the ResultSet option
654 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
656 --- 4.2.17 2011/09/28
658 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
659 with a flag whether to substitute escape sequences or not.
661 --- 4.2.16 2011/09/22
663 Fix nmem_strsplit_escape to substitute escape char properly.
665 New option for zoomsh -e , which makes it abort on first error and
666 return process exit code to indicate success/failure.
668 YAZ options utility supports special option -- which makes all it treat
669 all following arguments as non-options.
671 --- 4.2.15 2011/09/16
673 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
674 searched if absolute filename is given.
676 Fix conv_xslt() error-reporting when stylesheet is not found.
677 (The value of fullpath is meaningless in this situation.)
679 --- 4.2.14 2011/09/07
681 Fix problem in CQL sort node creation: un-initialized memory.
683 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
684 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
685 CQL sortby depending on whether Type-1 or CQL is actually sent to the
688 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
689 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
691 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
692 will make it possible to use both single-character mask (#) and wildcard (?)
693 in CCL . Throw diagnostic for left truncation because that is not supported
696 --- 4.2.13 2011/09/01
698 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
699 cases using escapes (\-sequences) and masking.
701 PQF parse fix: A trailing backslash followed by end-of-string (\0)
702 would result in a read one byte beyond string.
704 rpn2ccl may use Z39.50 masking for terms (t=z).
706 ICU check fix. Don't include library -lCrun on Solaris, unless present.
708 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
709 not --cppflags (which seeems like an error in icu-config).
711 --- 4.2.12 2011/08/27 RPM package only
713 cql2ccl: fix conversion of terms: operator characters were not
716 --- 4.2.11 2011/08/25 RPM package only
718 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
719 CCL parser will map both # and ? to their regular expression
720 quivalents (. and .*).
722 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
723 of reserved CQL characters.
725 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
726 is, so that they are passed through.
728 --- 4.2.10 2011/08/24
730 ZOOM SRU mode: more aggressive re-connect.
732 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
733 made available as a utility function, declared in <yaz/logrpn.h>
735 rpn2cql_structure() supports proximity nodes (except that the Type-1
736 proximity node's "exclusion" binary is ignored, as there is no way to
737 express that in CQL). Fixes bug #4564.
741 Fix SEGV that could occur if set command of zoomsh was given without
742 value (2nd argument).
744 Fix SEGV that could occur if unsupported transport was given for
745 COMSTACK - say https (when SSL was unavailable).
747 Build yaz-url on Windows too.
751 New utility to get web content. Header is url.h. A command line tool
752 yaz-url is part of the distribution and packages.
754 Fixes for SSL COMSTACK (when gnutls is in use).
756 New functions yaz_base64{encode,decode}. Header is base64.h.
760 ZOOM C includes HTTP response buffer as additional info if it fails
761 to decode the SRU response.
763 Make wrbuf_json_puts available.
767 zoom: throw diagnostic for invalid value for option "sru". Before a
768 bad SRU request was sent.
770 Adding new utility wrbuf_vp_puts.
772 Add cclxmlconfig.obj to win/makefile. It was missing completely.
776 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
777 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
778 redirect was used at the same time.
780 MARC line mode decoding: be less picky about length given - first
781 5 digits of header that is.
783 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
785 Changes to decoding of SRU records: a record with recordPacking=xml is
786 modified with a new root element <yaz_record> if the recordData contains
787 multiple children elements. This is to make the record XML parseable
790 RPN to Solr conversion: encode special characters.
792 Generic Frontend Server: fix uinitialized member, stepSize.
796 Fix a bug in SRU decoding of records.. The database records stored
797 had un-initialized memory, but it would only be seen with yaz_record_render
798 and type_spec="ext" .
800 Fix a bug in ccl_qual_dup introduced in 4.2.3.
804 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
808 Add new utilities to convert from CQL to CCL . These utilities have
809 prefix cql_to_ccl defined in cql.h.
811 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
812 lead to memory heap corruptions when ICU utilities were in use.
816 Make compilation work without Libxml2.
818 yaz-client: remove redundant blanks in display of searchResult-1 term
823 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
824 resulting CQL node (tree) in a new node CQL_NODE_SORT.
826 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
827 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
828 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
829 Note that the CQL sortby spec is only converted when the GFS is already
830 converting from CQL to RPN (cql2rpn element).
832 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
833 specify whether to collapse delimitors or not. The existing nmem_strsplit
834 do collapse (collapse parameter = 1).
836 Windows installer: For NSIS, set InstallDir depending on x86/x64.
838 Rename internal func yaz_use_attribute_create. While non-static, this
839 function is not declared in a public header.
843 Add -lCrun when linking with ICU on Solaris.
845 More quicks character set conversions for OPAC records.
849 fix problem with record_render: records were converted (character set
850 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
854 SRU: add methods for handling DADS SRU-proxy facets.
856 Separate OPAC record character set for ZOOM_record. yaz_record_render
857 allows a character set given as charset=from/opacfrom,to where 'from' is
858 the character set of a bibliographic record, 'opacfrom' is character set
859 of OPAC record and 'to' is the target character set.
863 yaz-client: show may XML format records. Command show followed by 'format'
864 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
867 src/stemmer.c: Avoid using unnamed union. It is not supported by some
870 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
873 Update yaz.spec to operate on both SLES11 / Centos 5.5.
875 RPM: Release includes 'indexdata' name. Use indexdata in release name so
876 this package can be distinguished from other vendors.
878 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
879 as determined by configure
881 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
883 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
884 returns no error and no record, the present request is considered
885 partial (only a subset of the records could be returned by backend), and
886 so it is appropriate to set Present Status to partial-4.
890 Move yaz-config man pages to section 1.
892 More documentation about Solr.
894 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
895 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
896 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
897 peers on some Linux systems. However, in general that does not work
898 so YAZ can not rely on that to work. Debian changed behavior in this
899 respect from Debian lenny to Debian squeeze (still testing as of Oct
901 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
903 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
907 Fix yaz-config output: echo_source not set correctly by configure.
911 Solr Web Service support for yaz-client and ZOOM.
913 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
915 --- 4.0.12 2010/08/17
917 Z39.50 facet support. Facet specifications are passed for search in
918 other-information with ASN.1 as defined in facet.asn and OID
919 .10.1000.81.5 . Facets are expressed as an Attribute list as known
920 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
921 3 is limit (number of entries to get in response). yaz-ztest returns
922 dummy facets if a client asks for them.
924 --- 4.0.11 2010/07/09
926 CCL fixes: bug 2895 and bug 3539.
928 GR1-display: add comma in display - was removed by mistake in
931 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
933 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
935 --- 4.0.10 2010/06/18
937 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
938 result set from a connection. The result set will be on its own
939 thereafter; no operations on it will perform retrievals from a target.
940 Only cached copies are returned.
942 ZOOM C:fix case for HTTP servers responding with Connection:close.
943 Ensure that if there is a current task it is resumed (like fetching
944 more records in a result set) . Bug #3484.
946 PQF parser: use odr_atoi for Odr_int (not atoi)
948 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
949 values that contain any non-digits are treated as string attributes
950 (previously decoding only checked for leading character ([0-9]). PQF
951 encoding: attribute string values are not surrounded by double-quotes.
955 New utility for managing threads - thread_create.h.
957 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
958 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
959 but YAZ' implementation do.
961 Fixes for yaz_cond-functions on Windows 7.
963 DLL export more symbols.
965 zoomsh: show record do NOT render opac.
967 Remove *.la files from Debian and RPM packages.
971 Debian package libyaz-dev depends on libgnutls-dev again (was
972 removed in YAZ 4.0.6, but due to Libtool it is still needed
973 even though yaz-config do not list libgnutls libs).
975 ZOOM: Use only one WRBUF for returning string results for
976 ZOOM_resultset. Reduces memory usage for ZOOM in general.
978 ZOOM: ZOOM_connection do not use a shared pointer to
979 ZOOM_resultset after ZOOM_resultset is destructed by
980 user. Reverts to YAZ 4.0.4 behavior.
984 record-conv: fix problem with at least one XSL conversion -
985 due to probably incorrect usage of XML XSL documents.
989 Fix yaz-config for static mode and the use of SSL (gnutls).
993 Forward decl timeval struct in mutex.h and gettimeofday.h.
995 yaz-config: fix 'static' mode linking.
999 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1000 are wrappers for pthreads or Windows. For Windows these are put in
1001 a separate DLL: yaz_cond4.
1003 libyaz.la (whole source) is compiled with thread. If thread support
1004 is enabled enabled, all source of YAZ is compiled with treading support.
1005 This allows core utilities such as yaz_log to use thread facilities.
1006 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1007 thread utilities. This commit moves mutex utilities (mutex.c) from
1008 libyaz_server.la to libyaz.la.
1010 yaz-json-parse displays leading text until error.
1012 --- 4.0.3 2010/04/09
1014 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1015 patch from Giannis Kosmas.
1017 SRU: no longer URL encode SRU database. The URL for an SRU server is
1018 a URL and such is alreeady encoded - at least when given with leading
1019 http:// or https://. This reverts behavior to YAZ 3.0.50.
1021 Support for new MARC XML notation TurboMARC which like MARCXML is a
1022 complete representation of MARC/ISO2709.. This one, however, is more
1023 compact and allows for faster processing with XSLT. TurboMARC can be
1024 used in the marcdisp.h API, from the yaz-marcdump utility and from
1027 yaz-ztest can be configured - via the database - to perform certain
1028 delays when it performs operations search, present and single record
1029 fetch. This allows testers to make yaz-ztest act as a real or even slow
1030 Z39.50 server. Refer to the yaz-ztest man pages for details.
1032 --- 4.0.2 2010/03/09
1034 wrbuf_destroy allows NULL WRBUF passed to it.
1036 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1038 Add ZOOM_connection_close.
1040 No fixed size buffers for ZOOM shell - bug #3257.
1042 tstodr: make it work on s390 platform.
1044 New icu iterator-functions. The new icu_iter-functions makes it possible
1045 to use ICU chains from many threads.
1047 yaz-client: better syntax check for show command.
1049 --- 4.0.1 2010/01/26
1051 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1054 New simple local-file XML include facility which allows file glob-patterns.
1055 Refer to yaz/xml_include.h.
1057 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1060 ZOOM_record_get supports new parameter "format" which makes it format XML
1063 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1064 JSONText in ECMA-262) is JSONValue, not JSONObject.
1066 --- 4.0.0 2010/01/20
1068 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1069 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1071 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1072 POSIX/Unix builds .so with major version 4.
1074 Remove old LOG_-defines from log.h. They have been obsolete and
1075 undefined by default for the last 5 years.
1077 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1079 GFS: Remove socket (int *fd) from search_rr handler. The socket
1080 descriptor ptr is a facility that allowed a search handler to supply
1081 a socket which would serve as a callback - when search was complete.
1082 This facility has now been in use for years.
1084 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1085 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1086 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1087 returns 'const char *' rather than 'char *. The returned string is
1088 read-only and should not be modified by applications. COMSTACK cs_close is
1089 now a void function - it no longer returns int. No applications check for
1090 the value and the implementations has always returned 0.
1092 ZOOM: use size_t for scan hit counts and str size. Functions
1093 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1094 occ (hit count) and len (string length) are now of type size_t pointer
1095 rather than int pointer. This is to be able to represent large hit counts
1096 and to also just to use the proper type for string length (strlen result).
1098 New JSON parser. Refer to include/yaz/json.h .
1100 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1101 Used to be int in some cases. Many wrbuf_-functions used to return an int
1102 indicating some length.. These return values were never used. And so they
1105 ODR: odr_malloc, odr_total now takes size_t for size.
1107 clone_z_type: fix leak; occurred for encoding failures.
1109 --- 3.0.52 2009/12/03
1111 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1112 bug was introduced in 3.0.51.
1114 --- 3.0.51 2009/12/02
1116 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1118 tcpip comstack: fix leak for getaddrinfo.
1120 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1121 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1122 Decoding of SRU "path" database is performed by private function
1123 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1124 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1126 yaz-client: honor base command for SRU. Change when database setting
1127 is applied for SRU and ensure it is kept when a connection is reset.
1128 Change also the way errors are displayed or SRU (decoding of packages).
1130 --- 3.0.50 2009/11/02
1132 Add support for extra request / response data for SRU codecs and GFS.
1133 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1134 for extra data response buffer and length. For the GFS, both request
1135 and response data (XML) is carried in extra_args and extra_response_data
1136 for the search handler. Patch by Ko van der Sloot.
1138 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1139 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1140 10010). This fixes bug #2113.
1142 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1143 cmdfile included a 'quit' command that would result in a memory violation.
1145 --- 3.0.49 2009/10/01
1147 Make a number of functions defined in xmlquery.c static. These have
1148 never been declared in a public header file (yaz/xmlquery.h) and was
1149 made public by mistake.
1151 Improve speed of character conversions (iconv utilities). This makes
1152 conversions from MARC-8 faster.
1154 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1155 unless type desired is "raw". This will prevent type "xml" from
1156 returning ISO2709 .. Which obviously can not be XML parsed.
1158 Fix memory leak in ZOOM that would occur if option apdulog was used
1159 on a re-used connection.
1161 Frontend server logs HTTP requests.
1163 Frontend server now sends Z39.50 close when it times out (sesssion has
1164 been idle for too long). Versions 2.0.30 and earlier also sent close.
1165 But due to a mistake this was disabled in all versions after that, i.e.
1166 the server would just close the socket immediately.
1168 yaz-client emits a better message when receiving an unrecognised
1169 userInformationField.
1171 Skip zero-length subfields when decoding ISO2709. This rare case happens
1172 if a record has two FS characters in a sequence. Without this patch
1173 there would be a reference beyond char array in using_code_len fragments
1176 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1178 --- 3.0.48 2009/08/28
1180 The show command offered by the zoomsh command now takes a 3d optional
1181 parameter type which is what is passed to ZOOM_record. If the type
1182 argument is omitted, "render" is used.
1184 RPN to CQL conv may use USE string attributes (bug #2978).
1186 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1188 --- 3.0.47 2009/07/08
1190 Function yaz_xml2query allows a diagnostic element in the PQF XML
1191 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1192 code and additional info respectively.
1194 The BER BOOLEAN is now the integral type Odr_bool which still happens
1195 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1196 typedef'd to Odr_int. This is still an integral 'int', but it may be
1197 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1198 ASN-1 compiler as well as programs has been updated to use the new types.
1200 --- 3.0.46 2009/06/08
1202 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1203 only the bibliographic record was rendered. For type=opac, an OPAC
1204 record is only returned if it is present.
1206 iconv: small fix for encoding of advancegreek.
1208 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1210 yaz-client: option auto_reconnect=on really reconnects.
1212 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1214 server: avoid null ptr ref for for yaz_poll errors.
1216 build: fix RPM build for RHEL 5.3.
1218 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1220 --- 3.0.45 2009/03/31
1222 Fixed bug #2709: TCP connect returns Invalid argument.
1224 Fixed compilation for mingw.
1226 Honor charset for raw records (ZOOM_record_get).
1228 Fixed use of errno for threaded mode that was seen on Solaris 10.
1230 Fixed argument passing with blanks in value for Windows Service.
1232 Disable YAZ' own log rotate by default (no 1 GB limit).
1233 The variable l_max_size which specifies the log file limit is set to 0
1234 (DISABLED): This is due to the fact that YAZ is most often deployed using
1235 logrotate. Also YAZ can not perform log rotate because of unsufficient
1236 permissions (setuid).
1238 --- 3.0.44 2009/02/17
1240 List supported encodings in man page for yaz-iconv.
1242 Fixed missing SSL libs for --libs output
1244 Re-established OID record syntax application-xml. Nobody should use it
1245 but we don't want to change soname because of this symbol being absent.
1247 --- 3.0.42 2009/02/02
1249 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1251 Added member named_result_sets for init handler struct for the GFS. This
1252 allows a server to disable named result sets.
1254 Removed OID record syntax application-xml.

1258 Fixed bug #1902: yaz-icu XML output.
1260 Make YAZ checks Emacs friendly.
1262 BITSTRING value shows value. Bug #2346.
1264 ISO2709 decoding: skip control characters from indicator data.
1266 Omit sort key by default in yaz-icu's output.
1268 Allow combined single char options (again) for YAZ' options function.
1270 Utility yaz-marcdump got option to display YAZ version (-V).
1272 Allow YAZ to use ICU 3.4.
1274 Added new ICU test case which illustrates removal of diacritics.
1276 --- 3.0.41 2008/12/29
1278 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1280 --- 3.0.40 2008/12/29
1282 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1285 Fixed bug #2352: yaz-marcdump crashes for certain record.
1287 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1289 Added support for Danmarc2 to UTF-8 conversion.
1291 Added support for ISO5426 to UTF-8 conversion.
1293 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1294 implementation version.
1296 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1298 --- 3.0.38 2008/11/10
1300 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1301 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1303 ZOOM C now interprets databaseName option for ZOOM connection as path
1306 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1308 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1310 Dummy Libxml2 types no longer defined in headers of YAZ'.
1312 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1315 --- 3.0.36 2008/09/26
1317 Various ODR chapter fixes.
1319 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1321 Added missing source for Windows compilation, mutex.c.
1323 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1325 For SRU connections in ZOOM all records up to "count" are now fetched.
1327 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1328 in Windows due to bad error handling for Libxml2.
1330 Added facility for sending arbitrary records (ASN.1 any) using
1331 ZOOM C's Extended service update. Patch by Sam Reynolds.
1333 New options for ZOOM C's connection, logapdu which makes ZOOM log
1336 --- 3.0.34 2008/06/18
1338 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1340 --- 3.0.32 2008/06/12
1342 Fixed memory violation that could occur when decoding UTF-8. This bug
1343 was only present in 3.0.30 of YAZ.
1345 --- 3.0.30 2008/06/06
1347 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1348 GNU TLS is used by default (if found).
1350 yaz-ztest returns OPAC records if a client asks for OPAC.
1352 Improved speed of MARC-8 encoding.
1354 Added support for lossy and loss-less MARC-8 encoding.
1356 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1358 Added new Windows Service wrapper (sc).
1360 yaz-client's itemorder command may now send a file.
1362 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1364 Added new function yaz_log_xml_errors.
1366 Allow (but warn) unknown XML attributes in MARCXML parsing.
1368 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1370 The UTF-8 to MARC-8 conversion now uses a different set of characters
1371 for Greek symbols. Bug #2120.
1373 --- 3.0.26 2008/02/21
1375 Added yaz_daemon (daemon.h).
1377 Fixed bug #2068: pkg-config trouble
1379 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1381 --- 3.0.24 2008/01/28
1383 Document --with-xml2 option.
1385 Added OPAC XML XSD (etc/opacxml.xsd).
1387 Allow glob mask for name attribute in retrieval element for the
1388 generic frontend server's retrieval facility.
1390 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1391 except POLLIN/POLLOUT.
1393 Fixed error handling in cs_listen. Bug #2037.
1395 --- 3.0.22 2008/01/20
1397 Fixed version in yaz/yaz-version.h.
1399 Fixed bug #2027: Crash when closing connection.
1401 Changed configure so that ICU support is only enabled if only ICU
1402 and Libxml2 is available (because the ICU chain is XML based).
1404 --- 3.0.20 2008/01/15
1406 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1407 is built. Only this DLL depends on the ICU runtime.
1409 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1410 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1412 Changed license of CCL module to 'Revised BSD'. After consultation with
1413 remaining members of the original EUROPAGATE consortium, we are re-issuing
1414 the CCL module without a separate license. The software was developed by
1415 Index Data as part of a research project. The special license was included
1416 to help feed usage information back to the project consortium to support
1417 project evaluation. At this time, the project consortium has long-since
1418 disbanded, and the majority of the original principals have retired. At the
1419 same time, we have significantly modified the software during the following
1420 years, to the point where very practically no original code remains. To
1421 simplify re-use of the software, we have contacted those members of the
1422 consortium who could be reached, and agreed to re-issue the module as a
1423 proper part of the YAZ package.
1425 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1427 CQL closer to being version 1.2 compliant. CQL also allows free-form
1428 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1431 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1432 bug could make Extended services handling crash in the ZOOM layer. This
1433 bug was only present in YAZ 3.0.18.
1435 --- 3.0.18 2007/12/19
1437 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1440 yaz-marcdump reads and writes collection wrapped records.
1442 Handle OPAC for record conversion module.
1444 Fixes for ICU wrapper.
1446 Allow ICU libs to be controlled with --with-icu .
1448 --- 3.0.16 2007/11/12
1450 Added yaz_poll which is a wrapper for select/poll. When poll is available
1451 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1452 sockets to be in use.
1454 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1455 functionality through an XML based configuration (ICU chain). This system
1456 is useful for search facilities such as Pazpar2 and Zebra that needs to
1457 perform tokenization of indexed material. The ICU code in a separate
1458 library libyaz3_icu.a.
1460 Added HTTP tunnel facility for COMSTACK, bug #1752.
1461 This is a facility that allows a Web proxy, such as squid, to tunnel
1462 Z39.50 traffic. This facility is "transparent" to must applications
1463 using YAZ. It's enabled by using pseudo transport connect: followed by
1464 the proxy address, followed by command, then follwed by he regular
1465 "virtual" addresss. For example,
1466 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1468 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1470 --- 3.0.14 2007/09/21
1472 Fixed bad memory reference in ZOOM_record - cuased by member not being
1473 initialized. This was a problem only in YAZ 3.0.12.
1475 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1476 fields were not removed.
1478 Changed the way C code is generated from codetables.xml. Made a MARC-8
1479 conversion trie for each characterSet section rather than codeTable.
1480 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1481 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1483 --- 3.0.12 2007/09/12
1485 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1486 from ZOOM_record_error).
1488 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1490 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1492 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1494 Better SRW-to-Bib-1 diagnostic mapping.
1496 ZOOM C and yaz-client announces SRU version 1.2 by default.
1498 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1501 Fixed in yaz_sru_decode to allow other version than 1.1.
1503 --- 3.0.10 2007/08/22
1505 Added support for SRU scan for ZOOM.
1507 Added support for the use of the older versions or Extended Service
1508 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1509 set to the version , 1=first, 2=second, 3=third. The third version is
1510 what ZOOM C has used so far. And that, obviously, is the default.
1512 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1513 therefore in Zebra and in SimpleServer-based applications). The new
1514 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1515 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1516 which is passed into the back-end search callback function.
1518 Added support for HTTP Basic authentication in clients: the SRU/W
1519 codec encodes the username/password elements of the PDU structure
1520 appropriately, and these may be set using the "user" and "password"
1521 options in ZOOM-C applications (the same options that are used for
1522 Z39.50 authentication).
1524 --- 3.0.8 2007/06/25
1526 Fixed bug #1208: SSL appears to be broken in ZOOM.
1528 Fixed bug #1206: Libxml2 include path weirdness.
1530 Added oid_name_to_dotstring.
1532 Allow elementSetName to be specified for ZOOM C record update.
1534 Allow waitAction to be specified for ZOOM C based for Extended Services.
1536 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1537 syntax OID. Bug introduced in YAZ 3 series.
1539 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1541 --- 3.0.6 2007/06/06
1543 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1544 directory. yaz-client now reads commands from file given by option -f
1545 if specified; then tries to read .yazclientrc in current directory.
1546 Failing that, it reads .yazclientrc from user's home directory.
1548 Added support for correlationInfo Note and ID for Record Update via
1551 Added yaz-client command querycharset which specifies character set for
1552 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1553 (termListAndStartPoint).
1555 Charset ISO5428:1984 is an alias for ISO5428-1984.
1557 Implemented a way to perform scan in a result set using Z39.50. This
1558 is achieved by attaching the result set name in the characterInfo
1559 (type InternationalString) of OtherInformation in the Scan Request PDU.
1560 The result set is identified in the otherinformation by the new OID:
1561 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1562 This allows for scan in result set and faceted search . Zebra did some
1563 of this in the APT term using attribute type 8 and value being result
1564 set. Using the OtherInformation approach for this is cleaner and easier
1565 to work with in proxies and the like. This facility can be used in
1566 yaz-client using new command setscan which takes a result set as first
1567 argument, start position (APT) as second.
1569 Changed decoding of SRU XML packed records to deal with servers that
1570 have recordData with XML data with multiple root nodes. Also make
1571 comparison for recordPacking case insensitive. Again, one server
1572 returns "XML" where others return "xml".
1574 For SRU responses allow Content-Type application/xml as well as text/xml.
1576 --- 3.0.4 2007/05/21
1578 Fixed bug in character set conversion of BER strings. Bug introduced
1581 --- 3.0.2 2007/05/08
1583 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1585 For OID class, use oid_class consistently.
1587 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1590 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1591 character set for bibliographic information interchange". By Giannis Kosmas.
1593 Added documentation on new OID API.
1595 --- 3.0.0 2007/05/02
1597 Changes to generic frontend server interface: added new member
1598 'query_charset' for bend_initrequest structure. A backend init handler
1599 should set this member to its native character set for query terms.
1600 When defined, the frontend server logic will announce this character set
1601 to a client if the negotiationModel bit is set by the client. All server
1602 implementors are encouraged to specify this. If a backend server does not
1603 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1605 Added CCL utility to remove terms (stop words) from resulting RPN
1606 tree. This is handled by functions with prefix ccl_stop_words_ .
1608 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1609 terms in RPN queries.
1611 Clean-up the CCL API. Moved some internal structures from ccl.h to
1612 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1613 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1614 This is replaced by ccl_parser_find_str which takes a string instead.
1616 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1617 libyaz.la is the core of YAZ except the generic frontend server and
1618 does not depend on POSIX threads anymore. libyaz_server.la is the
1619 generic frontend server facilities and uses POSIX thread functionality
1620 if available. The libyaz.la no longer depends on POSIX threads because
1621 the number of global structures is limited. NMEM no longer re-uses blocks
1622 between threads ; it simply free's memory immediately but allocates in
1623 "large" chunks as usual. We don't expect any performance penalties
1624 because of this. The yaz_log system is still using a global log_level so
1625 caution must be taken when modifying it with yaz_log_init_.. +
1626 yaz_log_mask_str. This, however, should not cause any trouble because
1627 these functions are called during initialization of application code
1628 anyway. `yaz-config --libs server` returns libs for server applications;
1629 `yaz-config --libs` returns libs for non-server applications.
1631 New OID database - with public definitions in oid_db.h. Removed old OID
1632 database including the head oid.h and definitions such as enum oid_value
1633 and struct oident. The new OID database uses the same string names as
1634 before but the 'protocol' is gone. There are now only two representations
1635 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1636 converts from string to OID; functions with prefix yaz_oid_to_string
1637 converts the other way.
1639 Change to emit_term() in CQL-to-PQF query translation: when a term has
1640 the /regexp relation modifier, do not process it for leading and
1641 trailing "^" and "*", which have quite different meanings in regular
1644 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1645 write handlers no longer carries a 'last' parameter. This will make
1646 yaz_iconv flush "less" characters. A flush is performed by call to
1647 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1649 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1650 removed, because function yaz_query_to_wrbuf does the same.
1652 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1653 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1655 Deprecated MARC utility functions removed.
1657 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1660 Branch split: YAZ_2_1_55_branch
1662 --- 2.1.54 2007/03/16
1664 Fix to ZOOM-C so that transparent reconnection is properly handled on
1665 connections that are in asynchronous mode.
1667 Fixed compilation on OpenBSD 4.0.
1669 Large strings in GRS-1 records are now properly displayed in yaz-client.
1671 Added character conversion support for "advancegreek"; based on patch from
1674 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1675 sequence is met. Before the error was not set so it would be unknown.
1677 Adjust yaz-marcdump MARC reader so that it skips until record separator
1680 --- 2.1.52 2007/03/07
1682 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1683 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1684 fd_set structure used as a bitmask for the FDs to be selected on.
1686 Using ACX_PTHREAD macro to check for POSIX threads.
1688 Fixed have-vsnprintf check.
1690 --- 2.1.50 2007/02/23
1692 Fixes for configure on BSD. Bug #900.
1694 Added snprintf/vsnprintf wrappers for systems that don't have
1695 limits (heavens forbid).
1697 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1698 created before all previous tasks were completed and removed from the
1699 task queue, the new task could be removed by a mistake.
1701 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1703 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1705 Fixed bug #832: Problem with MARC/charset in yaz-client.
1707 Fixed bug #668: save command line history for yaz-client.
1709 Fixed bug #830: pkg-config support.
1711 --- 2.1.48 2007/01/23
1713 Extended ZOOM result set options with two options that may be read by
1714 a client: resultSetStatus and presentStatus with values as specified for
1716 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1718 Fixed bug #827: Using SSL fails on Debian etch.
1720 Fixed bug #826: Weird looking chars for set of MARC records.
1722 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1723 that is treated as an ItemOrder with itemRequest being an XML document
1724 external. The value of "doc" is the content.
1726 Extended the GFS search facility. New member of bend_search_rr
1727 'estimated_hit_count' signals that hits is known to be an estmate
1728 (higher or lower than real hit count). New member 'partial_resultset'
1729 signals that the search was partial (hit count is lower or equal than
1730 real hit count). For Z39.50, the information is stored in resultSetStatus
1731 member of SearchResponse APDU. For SRU, the information is signalled
1732 via SRU diagnostic 59: "Result set created with valid partial results
1735 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1737 --- 2.1.46 2007/01/13
1739 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1741 Added ZOOM_connection_peek_event.
1743 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1744 the following new functions:
1745 ZOOM_event_nonblock, ZOOM_connection_process,
1746 ZOOM_connection_get_{socket,mask,timeout},
1747 ZOOM_connection_fire_event_{timeout,socket}.
1748 The existing blocking event handler, ZOOM_event, is a wrapper for the
1749 + blocking ZOOM_event_sys_{poll,select}.
1751 Implemented function ccl_xml_config which parses XML version of CCL
1752 configuration (bug #798).
1754 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1756 Added timings utility (yaz/timing.h)
1758 --- 2.1.44 2007/01/03
1760 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1763 Fixed bug #779: Rotation of apdu.log fails.
1765 Fixed for character set conversions:
1766 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1767 Honor G1 set in MARC-8 decoding.
1769 --- 2.1.42 2006/12/17
1771 Fixed bug #775: char conversion does not handle Alternative UTF-8
1774 Implemented function yaz_marc_read_line which parses MARC line format
1775 records. There is a wealth of formats out there. So far, this function
1776 reads line records produced by yaz_marc_write_line.
1778 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1779 more generic and easier to remember(!) options: -i format and -o format
1780 which specifies input format and output format respectively - where
1781 format is one of "marc", "marcxml", "line", "marcxchange".
1783 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1784 does not print anything except warnings for records.
1786 For yaz-marcdump, added support for MARC split into files (-s) with a given
1789 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1790 spec, at http://www.loc.gov/standards/sru/record-update/
1791 This has changed the binary layout of the following structs:
1792 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1793 bend_update_rr . Patch by Ko van der Sloot.
1795 Added GFS utility function bend_assoc_is_alive which returns 1 if
1796 association is still alive (client is connected); 0 otherwise (client
1797 closed connection). This allows busy servers to stop working for
1800 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1801 been a separate piece of software. This version of ziffy has been modified
1802 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1804 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1806 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1807 Client code may now interrogate options such as "init_opt_sort" to
1808 find out whether the server claims to support various options.
1810 --- 2.1.40 2006/11/27
1812 Added utilities yaz_{set,get}_esn to set/get element set name from
1815 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1816 of YAZ and has been so since YAZ 2.1.10.
1818 Implemented ZOOM_record_error which returns error information for
1819 record (surrogate diagnostic).
1821 --- 2.1.38 2006/10/31
1823 Updates for SRU Update by Ko van der Sloot:
1824 1. Changed name from "operation" to "action"
1825 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1826 versions in the code, marked as 'backward compatible'.
1827 3. Added diagnostics for SRU Update.
1829 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1831 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1833 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1835 For GFS, fixed problem with SRU diagnostic 'First record position out of
1836 range' being issued for 0 hits.
1838 zoomtst10 part of Windows Build.
1840 --- 2.1.36 2006/10/13
1842 Implemented yaz_filepath_comp which splits a path into file path
1843 components (required by Zebra 2.0.3+).
1845 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1846 BSD inspired license until now so this should not have any real impact on
1847 anybody. See http://www.opensource.org/licenses/bsd-license.php
1849 Fixed bug #687: Missing log lines.
1851 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1854 Fixed bug #689: SRU diagnostics to be added.
1856 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1857 whether a connection is idle (no more work do do).
1859 --- 2.1.34 2006/10/04
1861 Change type of optval from long to int for invocation of setsockopt with
1862 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1864 Added support for specifying the max log file size for the Generic
1865 Frontend Server. The size is given with option -r.
1867 --- 2.1.32 2006/09/21
1869 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1871 --- 2.1.30 2006/09/17
1873 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1876 Fixed bug in Generic Frontend Server that could cause a server to stop
1877 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1879 For the generic frontend server, the maximum record size is used as maximum
1880 size of incoming packages (SRU + Z39.50). The value until was previously
1881 only used in Z39.50 Init negotiation and, later, in a session controlled
1882 sizes of records returned. This is controlled using -k option. It can be
1883 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1885 --- 2.1.28 2006/09/04
1887 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1890 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1892 New option for yaz-marcdump -lpos=value which allows setting a portion
1893 of MARC header to a certain value.
1895 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1897 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1898 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1900 --- 2.1.26 2006/08/15
1902 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1905 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1907 --- 2.1.24 2006/08/08
1909 Fixed MARC ISO2709 encoding routines to deal with character set
1912 Minor changes to GFS logging. Database included in search request log
1915 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1916 cached/multiple records.
1918 Shared libraries are built by default on Unix+configure.
1920 Changed cql2pqf transformation to use a different evaluation order. The
1921 new order is: always, relation, structure, position, truncation, index
1922 and relationModifier. Old order was: always, relation, relationModifier,
1923 structure, index, position, truncation. Note that the the latter ones
1924 override former ones for identical attributes.. The new scheme means that
1925 it is possible to override any existing attribute with a relationModifier.
1926 And also that it is possible to override everything for the index rule
1927 (except the ones listed in relationModifier). No order is perfect but this
1928 one, we believe, covers more real cases.. The "always" should have been
1929 called "default", since the attributes there can be overridden with all
1932 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1933 compilation phase, but also for yaz-config --cflags output. This allows
1934 us to have public headers with Libxml2 stuff in them . It should also,
1935 eventually, make Libxml2 checks redundant in packages using YAZ, such
1938 --- 2.1.22 2006/06/15
1940 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1941 stored in uri, message and details.. Previously diagnostics were stored
1942 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1943 compatibility.. but he's probably the only one affected, so.
1945 Added support for CCL, compiled on the client side, in ZOOM-C. This
1946 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1947 input; the resulting query objects can be used for for searching with
1948 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1950 YAZ' configure searches for OpenSSL by default.
1952 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1953 SL_CTX_use_certificate_file. See
1954 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1955 for more info. Thanks to Ko van der Sloot.
1957 --- 2.1.20 2006/06/02
1959 Bug #600: SRU GET, POST support for yaz-client. Introduced
1960 command 'sru' which selects method SOAP/GET/POST.
1962 Allow missingValueAction to be specified for the sortspec string -
1963 function yaz_sort_spec. By default, the missing value action is null.
1964 Use ! to specify "abort". Use = followed by stringvalue to specify default
1967 Ensured that Present-handler (if defined) is called in GFS before any call to
1968 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1969 searchRetrieve requests.
1971 Documentation for YAZ is now based on the Docbook XML/XSLT using
1972 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1973 is no longer depending on jade/openjade or docbook-to-man scripts.
1974 PDF is no longer part of the distribution - but can optionally be
1975 made using DSSSL/jadetex or FOP.
1977 Added retrieval handling support in Generic Frontend Server to support
1978 conversion between MARC/XML as well as XSLTtransforms. See
1979 etc/yazgfs.xml for an example.
1981 Added Authentication support to Generic Frontend Server in SRU
1982 mode. Authentication using HTTP Basic is supported, as is the use
1983 of 'x-username' and 'x-password' parameters in the request itself.
1985 Added support for a new character set MARC8s identical to MARC8 except
1986 that it converts combined characters to single Unicode characters in the
1987 Latin-1 range (when possible).
1989 --- 2.1.18 2006/04/24
1991 ASN.1 compiler 0.4: generates brief Doxygen file header for
1992 generated .h/.c files.
1994 Utility yaz_iconv now supports conversion to MARC-8.
1996 New facilities for the MARC module. The reading - and writing of
1997 content are separate methods for the yaz_marc_t handle. The following
1998 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1999 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2000 format). Write functions have prefix yaz_marc_write_.. The existing
2001 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2002 available. Removed support for OAI-MARC and simplexml (not the
2003 simplexml from PHP5).
2005 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2006 to be returned for this connection.
2008 --- 2.1.16 2006/03/31
2010 Allow multiple languages and charsets to be specified with
2011 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2012 negcharset iso-8859-1,utf-8
2014 Translation of proximity nodes from CQL into PQF now works.
2016 Moved to automake 1.8, 1.9.
2018 Added function yaz_log_set_handler which allows a log handler to be
2019 installed. This handler will be called for all log messages. Output
2020 to file is also produced; but that can be disabled by passing NULL
2021 fname to yaz_log_init_file.
2023 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2025 For SRW (including GFS), accept application/soap+xml as content-type
2028 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2029 produces NO stylesheet reference even if a default stylesheet is specified
2032 --- 2.1.14 2006/03/14
2034 Updated Windows package to include yazd.dll + yazd.lib for the
2035 Development component.
2037 If the environment variable YAZ_LOG is set, then it is used as a
2038 string indicating the default level of logging to use if not
2039 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2040 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2041 used as before. So, for example, to omit warnings from YAZ logging,
2042 export YAZ_LOG=-warn
2044 cql_transform() now map structure and other attributes before indexes,
2045 so that index-specific structures and other attributes can override
2046 defaults. So now a combination of mapping specifications such as:
2048 index.dc.date = 1=date-modified 4=5
2049 does the right thing.
2051 cql_transform() now also respects the "always" mapping specification,
2052 which establishes an initial set of attributes to be used for all
2053 terms except where overridden by more specific attributes associated
2054 with the index, relation or modifier.
2056 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2057 which mode to use; one of "post", "get" or "soap" (SRW, default).
2059 Fixes for yaz_iconv routines: changed trie-based character set conversions
2060 to use only non-negative values for bit fields due to Sun's C compiler not
2061 supporting negative values.
2063 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2064 sequences where not read correctly. Fix by Rustam Usmanov.
2066 Updated win/makefile to use options, settings which makes things
2067 compile with VS C 2005.
2069 --- 2.1.12 2006/02/01
2071 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2073 In ZOOM socket code, use select instead of poll on MacOSX.
2075 ZOOM-C now support client-side compilation of CQL into RPN that is
2076 sent to the server, enabling CQL to be used against all Z39.50
2077 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2078 ZOOM_query object, and submit it using ZOOM_connection_search().
2079 The CQL-to-RPN translation uses a configuration file, the name of
2080 which must be specified in the Connection's "cqlfile" option.
2082 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2083 function, which takes as its start-term parameter a ZOOM_query object
2084 (which may have had either CQL or RPN set into it).
2087 --- 2.1.10 2005/11/29
2089 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2090 GFS to support this as well. Backend handler, bend_srw_update, does the
2091 update work. Code contributed by Ko van der Sloot.
2093 Allow retrieval of Search Result-1 information in ZOOM by the use of
2094 options that are attached to a result set. ZOOM documentation updated
2097 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2098 UTF-8 conversion. Patch by Raj Patel.
2100 Added option -m to GFS to control formatting of timestamps in log file.
2102 Added 'exit' as synonym for 'quit' in yaz-client
2104 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2105 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2106 for the new members. Patch by Ko van der Sloot.
2108 Added support for SRU POST. It is supported for content-type
2109 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2111 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2112 Instead make the library libyaz.la multi-threaded. Threading as a whole
2113 can still be disabled by configure option --disable-threads. Previosly,
2114 with older GLIBCs there were problems with MT libs under Apache. This
2115 has now been fixed a long time ago.
2117 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2120 CQL module modified to be case insensitive for relations/indexes/operations.
2122 Fixed bug in CQL transform code: incorrect value relationModifieder
2125 Added 'show all' command for yaz-client which retrieves all results
2128 Added new yaz-client, xmles, which takes a (private) OID and
2129 a document to be sent as an extended service request.
2131 Describe new yaz-client commands wait_response and set_auto_wait.
2133 Increase TCP/IP listener backlog from 3 (which I am guessing was
2134 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2135 that the socket will queue as many incoming connections as it's able
2136 to handle ongoing connections. In other words, it will never now
2137 refuse a connection that it would be able to handle merely because
2138 it's not got around to accepting() enough of the pending connections
2139 yet. This is the behaviour anyway under Linux, where the listen()
2140 argument is ignored; but not under BSD and on systems such as
2141 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2142 YAZ-based servers should now be uniform across operating systems in
2145 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2146 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2147 This allows yaz-marcdump to read large MARC batches (>2 GB).
2149 Modified all YAZ source files - except the source which is auto-generated
2150 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2153 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2154 corresponding to the existing *_setl() function. These allow option
2155 values containing arbitrary valuues.
2157 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2158 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2159 except that it returns an indicator of whether or not the sort
2160 criterion was accepted (0 for OK, -1 for invalid).
2162 --- 2.1.8 2005/06/07
2164 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2165 MARC output rather than returning "new" buffer.
2167 yaz-client warns about unknown init options.
2169 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2171 --- 2.1.6 2005/05/24
2173 Added support for SRW sort in Generic Frontend Server. Patch
2174 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2175 sortKeys - or NULL if none is provided.
2177 Fixed bug #307: It was impossible to specify indefinite/no timeout
2178 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2181 Added support for multiple languages and charsets to be specified in
2182 ZOOM. Each charset/language is separated by a blank. If negotiation is
2183 in effect in init-response, Option
2184 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2185 Code based on patch by Vasiliy Osadchuk.
2187 Fixed bug #306: infinite recursion that occurred when calling
2188 yaz_log_level_init as the first call (before other log level or
2191 Fixed bug in scan handling in front end server: if preferred-Position-In-
2192 Response was non-present, a NULL pointer referece was performed.
2194 --- 2.1.4 2005/04/26
2196 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2197 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2198 now defined for all those error codes. So instead of putting 109 in
2199 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2200 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2202 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2205 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2207 Program yaz-client now exits and produces an error message if multiple
2208 Z39.50 servers are specified on the command line (none or one allowed
2211 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2214 --- 2.1.2 2005/03/16
2216 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2218 Fixed bug #272: Preserve spacing for CCL terms.
2220 --- 2.1.0 2005/03/14
2222 Added support for virtual hosts and multiple backend servers for
2223 the YAZ frontend server. The configution is XML based and
2224 support specificition of CQL to RPN mappings and explain information.
2225 See section "Virtual Hosts" in the YAZ manual.
2227 Extended OPAC display utility. OPAC display utility renders
2228 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2229 to supplement yaz_marc_decode_wrbuf.
2231 Fixed a bug in MARC decoder that could caused it to crash for some
2232 invalid MARC records. More diagnostics and warnings where added in
2233 XML output (warnings, etc are stored in comments).
2235 --- 2.0.34 2005/02/08
2237 Fixes for UNIX domain sockets. Bug #261.
2239 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2241 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2242 Added yaz_marc_subfield_str which defines subfield lead string which is
2243 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2244 yaz_marc_endline_str which defines end of fields string used in
2245 YAZ_MARC_LINE format. Default string is newline.
2247 Experimental support for MarcXChange. This format can be produced
2248 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2249 http://www.bs.dk/standards/MarcXchange.xsd
2251 Added yaz-client commands scansize that sets maximum number of
2252 entries to be returned by scan.
2254 --- 2.0.32 2005/01/11
2256 Added support for SRW scan in yaz-client and Generic Frontend Server.
2258 * Added whereInList member to SRW Scan Term.
2260 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2262 Fixed NMEM system to return aligned blocks on the smallest boundaries
2263 that are suitably aligned for all possible types on the particular
2264 architecture YAZ is being built for.
2266 --- 2.0.30 2005/01/04
2268 Fixed numerious warnings that was issued with newer versions of GCC.
2270 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2271 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2274 Make YAZ Generic Frontend Server slightly faster.
2276 Enhance (and reduce) logging for Generic Frontend Server.
2278 Revert YAZ log system so that it flushes every write operation
2279 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2281 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2282 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2283 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2284 will effectively disable old definitions.
2286 --- 2.0.28 2004/11/09
2288 Added yaz_log_time_format which specifies log format using
2291 Added yaz_log_module_level which returns mask for a module. Value
2292 is non-zero mask a if module is enabled; zero if disabled.
2294 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2295 in include/yaz/cql.h.
2297 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2299 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2301 Fixed bug #172: RPM builds does not enable SSL.
2303 Doxyfile.in part of dist. Doxyfile generated by configure.
2305 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2306 are given and the corresponding component does not exist.
2308 Extend CCL documentation in YAZ reference. Describe r=r.
2310 --- 2.0.26 2004/10/01
2312 Fixed MARC->MARCXML conversion to properly deal with
2313 fields, subfields, indicators having non-ASCII characters.
2315 Fixed MARC->MARCXML conversion so that ASCII control characters
2316 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2319 Added YAZ GFS support for conversion from Z39.50 surrogate
2320 diagnostics to SRW surrogate diagnostics.
2322 Bug fix: YAZ GFS did not return schema in explainResponse.
2324 --- 2.0.25 2004/09/30
2326 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2327 now converts recordSchema to elementSetName as well as schema URI.
2329 Fixed bug in COMSTACK that prevented HTTP request packages from being
2332 --- 2.0.24 2004/09/29
2334 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2335 does not require white-space before and after the dash in a range, e.g.
2336 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2339 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2340 due to new GCC removing "redundant" code.
2342 Added yaz-client commands scanpos and scanstep that sets preferred
2343 position and step-size for scan.
2345 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2347 Added CCL utility ccl_qual_buf which parses one or more CCL
2348 spec lines in a buffer.
2350 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2351 of name and value - ignoring empty lines and comments.
2353 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2355 Added odr_get_element_path which returns current element path for an
2356 ODR handle. This utility is useful in error handling or user-defined
2359 Added ODR_PRINT utility odr_set_stream which is is a more generic
2360 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2361 to a write function and pointer to close function. The close function - if
2362 non-NULL - will be called during odr_destroy.
2364 Fixed bug in CCL parser where truncation char was not removed from
2365 right side when truncation=both was in effect.
2367 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2370 --- 2.0.23 2004/08/11
2372 Fix buffer overrun in CQL parser when dealing with proximity (%).
2374 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2375 to UTF-8/UCS conversion is now only based on codetables.xml.
2377 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2379 --- 2.0.22 2004/08/06
2381 Add support for more "commit changes" in ZOOM (uses Extended Services).
2383 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2386 Yet another small fix for configure of SSL.
2388 --- 2.0.21 2004/05/14
2390 Fix SSL libs for configure when --with-openssl=DIR is given.
2392 --- 2.0.20 2004/05/10
2394 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2396 SSL comstack now uses yaz.pem certificate file on server side
2397 by default. Certificate filename can be configured by calling
2398 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2400 Fix bug regarding multiple calls to ZOOM_connection_connect.
2402 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2404 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2405 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2407 ZOOM now allows inspection of X509 peer certificate for verification.
2408 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2410 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2411 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2412 as "modular" but it simplifies things.
2414 Added cs_get_peer_certificate to that returns peer X509 PEM.
2416 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2417 NULL if SSL is unavailable.

2428 This bug affects threaded version of GFS server.
2430 --- 2.0.18 2004/03/20
2432 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2435 Ensure zlib.dll is packed with Windows install.
2437 --- 2.0.17 2004/03/17
2439 Fix encoding of xsd:string to use text instead of CDATA.
2441 Fix endless loop in CQL parser with unbalanced ".
2443 Use a more compact way to store MARC-8 conversion tables.
2445 --- 2.0.16 2004/03/16 Debian only
2447 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2450 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2455 --- 2.0.15 2004/03/01
2457 Another fix for decoding of XML packed records.
2459 --- 2.0.14 2004/02/25
2461 Fixes for Chunked encoding. White space not ignored after length spec.
2463 Update NS and use default NS for SRW diagnostic elements.
2465 --- 2.0.13 2004/02/23
2467 Implement ZOOM_resultset_cache_reset which resets record cache.
2469 Implement ZOOM_resultset_sort which sorts a result set.
2471 Implement chunked HTTP transfer.
2473 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2475 --- 2.0.12 2004/02/16
2477 Added member 'schema' to bend_explain_rr structure so that backend
2478 can specify explain record identifier. Defaults to Zeerex 2.0.
2480 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2482 --- 2.0.11 2004/02/16
2484 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2487 Added init command for yaz-client which sends "extra" init request.
2489 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2490 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2492 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2494 Make ZOOM error code for "invalid query".
2496 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2498 --- 2.0.10 2004/02/05
2500 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2503 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2505 Added option -p <file> to make Generic Frontend Server to write PID file.
2507 Added option -D to put Generic Frontend Server in background on its own.
2509 Make ZOOM C recognize option "password". If unset, "pass" is used
2510 (for backwards compatibility).
2512 Fixed a bug in Generic Frontend Server that could make it crash if a
2513 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2516 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2517 Must be issued before open, in order to be in effect.
2519 --- 2.0.9-6 2004/01/12 Debian/Windows
2521 Make the SRU server more picky WRT unknown params, etc.
2523 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2525 New YAZ client command, options, that sets Z39.50 options.
2527 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2528 options from a string of tokens (one token for each option bit).
2530 Update SRW diagnostic code messages.
2532 --- 2.0.9-5 2004/01/07 Debian/Windows
2534 Handle user defined stylesheet for SRW/SRU.
2536 --- 2.0.9-4 2004/01/06 Debian/Windows
2538 Fix bug in decoding of Content-Length.
2540 --- 2.0.9-3 2004/01/06 Debian/Windows
2542 Fix a bug with decoding of XML packed records.
2544 --- 2.0.9-2 2004/01/05 Debian only
2546 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2548 Fix bug in SRW/SRU diagnostics decoding.
2550 --- 2.0.9 2004/01/05
2552 Fixed bug in Generic Frontend Server which could drop records exceeding
2553 preferred message size. Reported and fixed by Irina Dijour.
2555 Fixed calculation of package size for structured records in Generic
2556 Frontend Server. Reported and fixed by Irina Dijour.
2558 Fixed namespace for SRW/SRU diagnostics.
2560 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2562 --- 2.0.8 2003/12/22
2564 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2565 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2568 CQL changes to reflect recent changes to the specification:
2569 * Documentation talks about context sets instead of index sets.
2570 * Documentation talks about indexes instead of qualifiers.
2571 * The CQL-to-PQF transformer's configuration file now uses
2572 "index.set.name = <attributes>" instead of the old form
2573 "qualifier.set.name = <attributes>". (Both forms are still
2574 understood but the latter is deprecated.)
2575 * CQL terms with no explicit index specified are now interpreted as
2576 cql.serverChoice instead of srw.serverChoice (which of course
2577 behaves exactly the same.)
2579 --- 2.0.7 2003/12/16
2581 MARC conversion can now generate ISO2709 output in another
2582 character set. yaz-marcdump uses this facility if you invoke it
2585 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2586 functions from there can be used from C++.
2588 --- 2.0.6 2003/12/04
2590 Frontend server now transfers memory from decoded packages to stream
2593 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2594 references to show up.
2596 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2597 the ZOOM Abstract API. The older names for the same options are still
2598 also supported for the benefit of old applications.
2600 ZOOM-C supports "implementationId" and "implementationVersion" options
2601 to go along with "implementationName". These allow the user code to
2602 specify identification strings to be sent to servers.
2603 Add OID for the new ExtLite attribute set.
2605 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2606 as requested/supplid by Ere Maijala <ere@atp.fi>
2608 For generic frontend server, reverse the order of
2609 "toolkit-supplied / application-supplied" strings sent as implementationId,
2610 Name and Version. Also, remove the spaces around the slash. This brings
2611 the GFS in line with the behaviour of ZOOM-C on the client side.
2613 Add function ZOOM_scanset_display_term.
2615 yaz-client shows scan displayTerm if present.
2617 Utility yaz-iconv is now installed by default along with the man page
2620 Extend configure check for OpenSSL to use pkg-config where available (such
2623 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2624 server to specify uid/gid/mask for socket using the format
2625 unix:[user=uid,][group=gid,][umask=mask,]file=path
2626 If file= is omitted the existing format is assumed, e.g.
2628 in which case the mask is 0666 (rw for everybody).
2630 Major restructure of YAZ source. All source in libyaz is in src directory.
2631 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2632 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2634 Added man page for utility yaz-marcdump (used to be called marcdump).
2635 yaz-marcdump is installed by 'make install'.
2637 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2638 of incoming package failed.
2640 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2642 Change prototype of odr_perror: add const to message string.
2644 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2646 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2647 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2648 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2649 DNS lookup. There should not be any compatibility problems with this
2650 assuming that blocking=1 or 0 is used.
2652 Fix bad reference in UNIX comstack in function cs_addrstr.
2654 Fix for compilation on AIX.
2656 The generic front-end server (server/seshigh.c) now supports returning
2657 Init diagnostics to the client in User-information-field, in
2658 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2661 --- 2.0.4 2003/09/04
2663 Allow any CQL relation (not just all,any,exact,scr).
2665 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2666 that features the same UI.
2668 Implemented command update0 in YAZ client which is equivalent to
2669 update but uses old of Ext Update ASN.1.
2671 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2672 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2673 Previously no OID was used for this info.
2675 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2676 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2677 returns 'malformed search term' otherwise.
2679 SortResponse member resultCount now set to NULL in sort handler of
2682 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2685 Add three new utility functions for translating OIDs between various
2686 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2687 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2688 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2689 char *oid_to_dotstring(const int *oid, char *oidbuf);
2690 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2692 Reverted modifications for ES Update definition for z_IU0Update
2693 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2694 is back to YAZ 2.0.2.
2696 String value attributes for CCL parser.
2698 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2699 which their FirstSearch server returns in Init responses, sometimes
2700 carrying useful diagnostic information when Init fails. This has the
2701 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2702 "z39.50/oclcui.asn", where its definition is somewhat different from
2703 what OCLC document on their web-site, as required to interoperate with
2706 Support for anonymous authentication in yaz-client. Use the command
2709 * Fix the OID of the Index Data-local "admin" Extended Service from
2710 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2711 the 1000, which indicates a locally-defined OID, was a mistake.
2713 --- 2.0.3 2003/06/20
2715 Fix CCL directive @case handling so that it affects string match for
2716 both CCL keywords and qualifiers.
2718 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2719 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2720 Decoder has been updated with ASN.1 changes as listed in
2721 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2722 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2723 z_IUUpdate, remains unchanged.
2725 ZOOM_record_get may now return a record in a specific character set.
2726 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2727 "from" is the character set of record as returned by target. "to" is
2728 the character set to be returned. If omitted, "to" is UTF-8.
2730 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2732 New ODR utility, odr_getelement, which returns name of element for
2733 which encoding/decoding failed.
2735 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2736 in cases where a required element was omitted.
2738 Bug fix: some MARC8 sequences were not converted.
2740 New ZOOM option "step" which specifies number of records to be
2741 retrieved in one chunk. Used in conjunction with "start" and "count".
2743 SRW support for yaz-client. Use scheme http: to use it, e.g.
2746 yaz-client no longer does (un)intelligent character set conversions
2747 by default. Can be enabled with charset and marc_charset commands.
2749 xmalloc trace fix for 64-bit systems such as DEC alpha.
2751 Solaris 2.6 compile fix.
2753 New function, cql_strerror() translates SRW error codes, as returned
2754 by cql_transform_error(), into human-readable English strings. Used
2755 in yaz-client diagnostics when appropriate.
2757 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2758 converts it into a type-1 query which is sent to the server. This
2759 makes CQL available for use with all Z-servers, as opposed to the tiny
2760 minority that can handle CQL queries themselves.
2762 --- 2.0.2 2003/04/28
2764 New Debian package layout similar to the Redhat Package layout.
2766 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2767 and search result respectively.
2769 --- 2.0.1 2003/04/25
2771 Redhat package is now several packages: libyaz (runtime libraries),
2772 libyaz-devel (development and documentation, and yaz (utility programs).
2773 Package spec file by Morten Bogeskov.
2775 New member 'schema' in struct bend_fetch_rr which the name of requested
2776 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2777 handler MAY set this to reflect the schema of the returned record.
2779 New member 'display_term' in struct scan_entry. GFS now sets member entries
2780 and allocates scan entries to be filled by user scan handler. In previous
2781 version, entries member was allocated by the scan handler. That still works,
2782 but the GFS will ignore member display_term - assuming it was NOT set by
2783 the handler. The fact that the GFS now allocates the entries both allows
2784 for new members and makes a scan handler easier to write.
2786 Fix CQL lex buffer overflow.
2788 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2789 SRU default recordPacking is string.
2791 SRU protocol support for frontend server.
2793 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2795 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2797 Added scan for the ZOOM shell (zoomsh).
2801 * String Identifers for Schemas (Amendment 5).
2802 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2803 Old definition for schema
2804 Odr_oid *schema; /* OPT */
2809 Z_InternationalString *uri;
2810 #define Z_Schema_oid 1
2811 #define Z_Schema_uri 2
2814 * resultCount parameter to Sort Response (Amendment 1).
2815 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2817 Support for SRW 1.0 over HTTP. This is an optional feature and
2818 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2821 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2822 on the same port. SRW SearchRetrieveRequests are mapped
2823 to bend_init,bend_search,bend_fetch,bend_close.
2825 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2827 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2828 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2830 ZOOM connections are SRW based if schem http is used for hostname
2831 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2832 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2834 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2835 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2836 distance=n, order=true/false, relation=le, prox unit=word. If
2837 n is omitted, distance 1 is used.
2839 Fixed problem with C compiler include path in wrong order.
2841 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2842 on Solaris. Patch from Ko van der Sloot.
2844 New MARC decode API. All new functions operate on a yaz_marc_t
2845 handle. The most important new functions are: yaz_marc_create,
2846 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2847 decode and destroy respectively. Decoder can produce formats
2848 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2849 include/yaz/marcdisp.h.
2851 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2852 to UTF-8, UCS-32, wchar_t or Latin-1.
2854 * Prototypes for yaz_iconv_-functions moved to separate header
2855 include/yaz/yaz-iconv.h.
2857 Make a few private functions 'static' in unix.c. This prevents
2858 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2860 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2861 are set when Init Response is received.
2863 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2864 but returns diagnostic set as well.
2866 New function yaz_strerror which is a portable wrapper for
2867 strerror/strerror_r/GetLastMessage.
2869 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2870 is returned for MARC. If type is "oai", then OAI MARC is returned.
2872 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2875 --- 1.9.2 2002/11/26
2877 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2879 Fix bad race conditions on SIGTERM and terminate gracefully in
2882 Move retrieval (data1) module to Zebra since nobody seems to be
2885 Add GRS-1 render for ZOOM using same format as yaz-client.
2887 --- 1.9.1 2002/10/05
2889 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2891 Fix broken ESpec handling in data1 module.
2893 SGML reader parses comments and makes them part of the data1 tree.
2895 Added several type casts so that YAZ compiles as C++ code.
2897 ZOOM didn't handle PDU encoding failures properly.
2899 Added more Bib-1 diagnostics (approved extensions).
2901 GNU configure: better check for iconv.
2903 More portable use of accept, getpeername. Check for socklen_t. Use
2904 int/size_t if socklen_t is not defined.
2908 PQF parser rejects bad queries - including those with extra
2909 characters in them. PQF parser used to silently ignore that.
2910 Cleaner API for PQF added, which allows you to get detailed
2911 error information for bad queries (see yaz/pquery.h).
2913 Fixed bug in ZOOM_record_get for type "database".
2915 Implemented mini iconv library supporting conversions between
2916 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2918 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2920 --- 1.8.9 2002/08/20
2922 Fixed ZOOM C record cache so that preferredRecordSyntax and
2923 elementSetName is used to check for already fetched records.
2925 --- 1.8.8 2002/08/02
2927 Added three members in bend_initrequest structure to facilitate
2928 character set negotiation.
2930 Fixed a bug in frontend server that could cause indefinite
2931 loops under rare conditions.
2933 Revised character set utilities (charneg.h) so that encoding
2934 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2936 For PQF, directive @term <type> sets term type for Scan/Search.
2937 Here <type> is general, string, numeric, null. The term type
2938 is inherited - just like @attr.
2940 New call odr_set_charset that sets character set conversion for
2941 international-strings on a ODR stream. Prototype is:
2942 int odr_set_charset(ODR o, const char *to, const char *from);
2943 The InternationalString is still represented as C string in YAZ
2944 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2945 won't). On the protocol level, you can use any encoding.
2947 Support for UNIX sockets in ZOOM.
2949 Solaris recv sometimes returns errno == ENOENT. It is treated as
2950 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2952 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2953 both client and server. Code by Morten Bogeskov.
2955 --- 1.8.7 2002/05/22
2957 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2958 that they can be used directly from Visual Basic. You must recompile
2959 your windows APP if you're using ZOOM.
2961 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2962 Commands "lang" and "charset" sets language and character set respectively.
2963 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2964 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2966 Attributes from multiple CCL fields may be OR'ed rather than merged
2967 using directive "@field or". Fields are still merged by default -
2968 equivalent to "@field merge".
2970 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2973 Fixed bug in zget for parameter ExtendedServicesResponse.
2977 --- 1.8.6 2002/03/25
2979 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2981 Client displays USR.1:SearchResult-1 (hits per term).
2983 Additional Search Info for search in Generic Frontend Server.
2985 Fixed CCL parsing of "field=s".
2987 WIN32 installer - using the excellent NSIS software from nullsoft.
2989 Fixed CCL parsing of "field = - <number>".
2991 Added function yaz_marc_decode that decodes MARC for line mode
2992 display or XML (similar to that used by JZKit).
2994 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2995 Z39.50. But ISO/ILL was, however.
2997 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2998 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3000 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3001 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3003 --- 1.8.5 2002/02/03
3005 New YAZ client features: Command completion and new commands:
3006 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3007 Code provided by Jacob Poulsen.
3009 New call oid_trav, that visits all registered OIDs via callback.
3011 Function ZOOM_record_get now returns const char pointer rather than
3012 void pointer. It saves a lot of type casts.
3014 For YAZ client, command "auth" now allows you to set authentication
3015 in IdPass style. It is enabled when three tokens are given - order
3016 is user, group and password.
3018 Fix memory leaks in MARC record handling for ZOOM.
3020 New option for YAZ client, -k <kilobytes> that sets
3021 maximum record size. Similar to -k option for generic frontend
3022 server and yaz-ztest.
3024 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3026 Prefix query parser reports "fail" when bad attribute set is given.
3028 Fix in MARC decoder. Proximity logging. Fix for attribute set
3029 in scan handler for server. Patches by Shigeru Ishida.
3031 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3034 Configure option --with-openssl=<dir> now works when a directory is
3035 specified. Patch provided by Morten Bogeskov.
3037 New option for YAZ client, -u <auth>, that sets authentication.
3039 ZOOM fix: error information was sometimes "missing", since error
3040 was cleared/reset too when it shouldn't.
3042 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3044 --- 1.8.4 2002/01/04
3046 Scan for ZOOM API. New object ZOOM_scanset. New functions
3047 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3048 ZOOM_scanset_destroy.
3050 New ZOOM function, ZOOM_connection_last_event, that returns type
3051 of last event (such as "receive data", "send data", "apdu received",
3054 New ZOOM option, schema, that specifies schema for retrieval.
3056 New CCL feature. Qualifiers can be aliases for one or more
3057 other qualifiers (if more than one is given, OR is used).
3059 ZOOM uses named result sets if target supports it.
3061 Two new YAZ client commands: . (dot, which sources a script of YAZ
3062 client commands), and ! (to execute shell command.). Implemented
3065 Working on Debian packages.
3067 --- 1.8.3 2001/11/19
3069 YAZ client enables named result sets only if target supports it.
3071 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3073 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3074 with key="host" to get same result.
3076 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3077 Function Z3950_resultset_record(s) returns references to records
3078 "owned" by resultset. To become owner use Z3950_record_clone.
3080 Function z_ext_record handles Extended Services. Thanks to
3083 --- 1.8.2 2001/11/12
3085 CCL Parser fix: ignore token comma when dealing with and-lists.
3087 Documentation updates for COMSTACK.
3089 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3090 Changed prototype Z3950_records. For some functions, int parameters
3091 were changed to size_t.
3093 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3096 New MARC decode/display function, marc_display_exl, which properly rejects
3097 non-ISO2709 records. YAZ client uses it.
3099 --- 1.8.1 2001/10/29
3101 Fix bug: local attribute set wasn't set correctly in PQF strings.
3105 * Old Z39.50 codecs no longer supported.
3107 Added ZOOM C binding. See http://zoom.z3950.org/
3109 Renamed states for COMSTACKs to avoid confusion with events.
3111 Implemented cs_look and proper cs_rcvconnect.
3113 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3115 Configure detects POSIX threads on OpenBSD.
3117 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3118 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3120 When error is returned from present handler, non-surrogate diagnostic
3121 is returned in present response (and fetch handler is no longer called).
3123 * Minor adjustments to pquery parser (PQF). Token characters may be
3124 escaped by using backslash (C-style).
3126 PQF parser allows string attribute values to be specified. For @attr,
3127 non-numeric characters after the equal-sign are treated as strings
3128 (e.g. @attr 9=title).
3130 CCL trunction character may be defined (@truncation in file)
3132 * function zget_ExtendedServicesRequest sets waitAction to
3133 waitIfPossible (was wait).
3135 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3138 CCL operator names may be set in field definition files (CCL_bibset).
3139 See ccl/bib1 for an example.
3141 Fixes in ASN.1 compiler for C++ compatibility.
3143 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3144 and "op_or" to avoid conflict with C++.
3146 Fixed problem with GNU readline detection on Redhat 7.0.
3148 Added step-size for Scan backend handler.
3150 Fixed bug that made the frontend server crash when no attribute
3151 set was specified for scan.
3153 Front-end server automatically switches to original working directory
3154 when installed as an NT service. Previously -w had to be specified to
3157 Added extended attributes for retrieval module (data1), so that data1
3158 records carry d1_readXML/SGML attributes. d1_read also supports
3159 null-data rules ( <tag/>)
3161 On UNIX when POSIX threads are available, a separate library libyazthread
3162 is created. Programmers should link with that library and the yaz library
3163 when using threads. The reason for the split was that some applications
3164 on Linux, such as Apache, doesn't work well when using shared objects that
3167 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3168 (or any frontend server) in SSL mode by specifying ssl: followed by
3169 address. Only tested on UNIX.
3171 Added feature for CCL module. Virtual structure s=al or s=ol generates
3172 and-list and or-list respectively instead of phrase search.
3176 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3177 log_mask_str. This was done to avoid name conflicts with other libraries
3178 (such as other PHP extensions).
3180 Added raw OID member for preferred record syntax (request_format_raw)
3181 and returned record syntax (output_format_raw) for backend fetch method.
3183 Config file yaz-config now accepts options so that it returns specific
3184 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3186 Shared library support for UNIX using GNU libtool.
3188 * Modified backend interface. Request/Response struct's replaced by
3189 one read/write C struct. For example bend_fetchrequest and
3190 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3191 Every handler - even search has to be registered in bend_init
3192 handler. This means that the YAZ library no longer refers to
3193 external functions and it makes it possible to make the whole
3194 thing a single DLL/SO.
3196 Added Segment handler for backend server.
3198 Added Zmbol/Zebra administrative functions to YAZ client.
3200 Threaded frontend server on UNIX (when POSIX Threads are available).
3201 Starting the server with option -T enables multi-threading.
3205 Added configure option --enable-comp/disable-comp to control use
3206 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3207 located in sub directory asn.
3209 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3210 in ${exec_prefix}/bin along with the other programs yaz-client and
3213 GNU automake used to maintain makefiles.
3215 Added several OID's.
3217 Changed retrieval module so that we can load records with no abstract
3218 syntax defined. Tagpaths in these records are fully composed of string
3221 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3225 On UNIX, the generated makefile now supports a proper 'make install'.
3226 The prefix can be set via GNU configure to set the install location
3227 (default is /usr/local).
3229 * YAZ programs client and ztest were renamed to yaz-client and
3230 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3231 locations, such as /usr/bin,/usr/local/bin,etc.
3233 * YAZ Header files were moved from include to include/yaz. YAZ Header
3234 files are referred to as include <yaz/log.h> rather than <log.h>.
3235 The YAZ include path (-I ..) is therefore the same as before. Programmers
3236 should update their #include statements or use -Ipath/include/yaz
3237 instead. The main motivation for doing this change is that YAZ header files
3238 can be installed in "standard" locations /usr/include,/usr/local/include
3239 without introducing conflicts, since ALL YAZ header files are stored
3240 in subdirectory yaz (under /usr/include for example).
3242 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3243 rather than project/workspace files. We switched because project files
3244 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3247 Changed name of logging function, logf, to yaz_log, to prevent name
3248 clash with some math-log functions. The YAZ header log.h defines logf
3249 to yaz_log (#define) so there should be no incompatibilities by this
3252 Added bend_start/bend_stop handlers for server. These handler are
3253 called on start/stop of server. For windows they are called whenever
3254 a service is started/stopped.
3256 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3257 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3258 in util/yc.tcl. The auto-generated C code structures are, in a few
3259 cases, incompatible with the old decoders. There are differences in the
3260 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3261 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3262 The preprocessor variable ASN_COMPILED is defined when the compiled
3263 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3264 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3265 wish to use the old encoders/decoders you can specify --disable-yc
3268 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3269 version so that it supports both new - and old version of DB Update
3271 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3272 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3273 change. The name parameter can be set to 0 in which no name is specified
3274 for the construction. The macros odr_implicit and odr_explicit sets name
3275 parameter to zero for the construction involved. New macros
3276 odr_implicit_tag and odr_explicit_tag are similar to the others,
3277 except that a name parameter is added. For programmers' that don't use
3278 ODR they probably only need to change the call to z_APDU and z_External.
3280 Added access control facility by interfacing the TCP wrapper library.
3281 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3282 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3283 name of the daemon and enables the access control as specified in
3284 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3286 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3287 den Dool <H.M.vdnDool@kub.nl>.
3289 Added reference ID parameter to most functions in server API - refer
3290 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3292 Changed name of ccl library to libccl.a (was ccl.a).
3294 Fixed bug in decoder for Explain (Category TargetInfo).
3296 Added support for GNU readline in client. Thanks to Jacob Poulsen
3297 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3299 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3300 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3301 IMPLEMENTATION! This change was made to the development version before
3302 the ZIG decided to retract the amendment. If any users MUST be
3303 compatible with the original Update definition, PLEASE CONTACT US, and
3304 we will include a separate definition corresponding to the old Update
3305 ES. Note that because of the change to the ASN.1 of the
3306 TaskPackageRecordStructure we cannot define a single structure that
3307 will support both versions.
3309 * Added const modifier to buffer parameter for some ODR/BER encoding
3310 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3311 completeWAIS, odr_dumpBER.
3313 Fixed bug in client.c which caused a crash when a scanResponse didn't
3314 contain positionOfTerm.
3316 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3317 * will cause an error in a client if a non-YAZ target sends both a
3318 * list of Scan entries and non-surrogate diagnostics.
3320 Retrieval module enhancements. Tag sets may be typed in the reference
3321 to it. From the .abs-file the "tagset" directive takes a third optional
3322 integer type for the tag set referenced. From a .tag-file the "include"
3323 directive takes a third optional type as well. The old "type" directive
3324 in the tag set itself is still recognized but acts as the default type
3327 Backend interface change. Individual Scan terms returned from bend_scan
3328 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3329 in include/backend.h.
3331 Retrieval module enhancements. Multiple tag sets and attribute sets may
3332 be specified in abstract syntax specs. Revised the error/warning for
3333 logging messages reported by the retrieval module when reading the
3336 Object Identifier system (oid_..) changed. The API is backwards
3337 compatible but the oid-routines now allocates new OID's when needed.
3338 Raw OID's may be specified in oid_getvalbyname.
3340 YAZ now uses GNU configure to generate Makefile(s).
3342 * Minor changes in some of the member names of DeleteResultSetRequest and
3343 DeleteResultSetResponse. See include/proto.h.
3345 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3346 and added member 'languages' in TargetInfo (which was missing).
3348 Changed the way attribute sets are handled in the retrieval
3349 module. These are now cached, just like the abstract syntaxes
3352 Changed YAZ so that it links with compiled ASN.1.
3354 Added Explain-schema definitions and mapping routines. The following
3355 Explain categories have been implemented: AttributeDetails,
3356 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3358 Fixed minor bug in Windows version of Server Library.
3360 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3362 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3364 Added EXTERNAL: UNIverse Resource Report (non-standard).
3366 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3367 ENUMERATED and SET OF.
3369 * Added 'const' to some of the char pointer arguments for the
3370 functions, data1_read_node, data1_getelementbytagname,
3371 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3374 Fixed bug in data1_insert_taggeddata - the last_child member of
3375 parent wasn't initialised.
3377 * Changed data1_read_record and data1_read_node so that the supplied
3378 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3379 doesn't refer to any parts of the "SGML"-buffer.
3381 Fixed bug in server library (Windows version of statserv_remove).
3383 * Changed code so that it compiles as C++. The type definition
3384 of Odr_fun which is a member of Odr_arm was changed. The result is,
3385 that an explicit typecast is needed for the fun pointer when
3386 using Odr_arm - as in:
3387 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3389 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3391 Implemented the new structured date and time definition as approved
3392 by the ZIG. Added schemaId element to the specificTag in Espec-1
3393 (also approved at the last ZIG). Thanks to RVDM.
3395 Added some Object identifiers (RVDM).
3397 Changed the Update Extended Service (RVDM).
3399 Added command "refid" to client which specifies referenceId for
3400 the following requests.
3402 Implemented extended service handling for server. See ztest.c
3403 for an example as well as backend.h. New handlers are registerd
3404 in the Init handler.
3406 * Changed interface for sort in server.
3408 Added new members to statserv_options_block. It allows a server
3409 to read options from another source than just the command line. Thanks
3410 to Charles Woodfield.
3412 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3413 renamed to zboolean. Some C++ compilers complained about the name.
3415 Minor changes to gils.abs. Added index 's' (sort) on title
3416 and date/time-last-modified.
3418 --- 1.4pl2 1998/1/30
3420 Fixed bug in server library regarding inetd mode (-i). This bug
3421 was introduced by release 1.4.
3423 --- 1.4pl1 1998/1/29
3425 Added sort facility in client and backend server interface.
3427 Fixed problem with dependencies in Makefile(s).
3429 Fixed bugs for encoders/decoders of extended services and
3432 Implemented sub-tree feature for schemas. Sub-trees are
3433 referenced in *.abs-files. See explain.abs for an example
3434 of the use of this feature.
3436 Modified bib1.att; local attributes for ANY didn't include
3437 ANY itself (only affects use of the retrieval module).
3439 Fixed bug in plain SGML reader in function data1_read_node:
3440 tags with prefix "var" was incorrectly interpreted as variants.
3442 Added feature "sub-schemas" to enable references to - and definitions
3443 of - group of elements.
3445 * Removed member parent from type data1_element (in data1.h).
3447 Implemented function odr_nullval() that returns the value of
3450 * Removed member num_children from data1_node (in data1.h).
3452 Made NT service interface part of the server library. The
3453 function statserv_main uses the NT service when required and
3454 calls the statserv_start / statserv_close routines.
3456 Routine zget_SearchRequest and zget_PresentRequest fills
3457 resultSetName/Id member with "default" instead of "Default".
3459 Fixed memory leak in server. Request queue member wasn't freed.
3461 Fixed nmem_exit so that memory is freed.
3465 Revised the CCL parser utility to be thread safe.
3467 Added function, oid_ent_to_oid, to replace the function
3468 oid_getoidbyent, which is not thread safe.
3470 * Added nmem_init and nmem_exit to initialize and release
3471 NMEM resources. Function nmem_init should be called once in the
3472 initial thread before NMEM/ODR is used. statserv.c and client.c
3473 have been changed accordingly. The change was necessary to make
3474 NMEM thread safe. The NMEM memory pool is shared amongst threads
3475 in a process. Unix-based applications will still work fine without
3478 Added NT Services interface for the the Z39.50 (statserv) Server.
3479 Refer to the ztest.c source on the usage.
3481 Windows 95/NT port using MSVC5.0. Project files are included in the
3484 * Defined new 'global' handle for the retrieval (data1) system. The
3485 new handled, data1_handle, describes the state of the data1 system.
3486 This handle is passed as first argument to virtually all
3487 data1 related routines. The functions data1_create and data1_destroy
3488 creates and destroys a data1 handle respectively.
3490 Added ODR encode stream member to all backend request structures
3491 init, search, scan etc. This stream should be used to allocate all
3492 memory used for the response when thread safe operation is needed.
3494 Changed the comstack utility, cs_addstr, to be thread safe. The
3495 returned hostname string returned by the function is now part the
3498 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3499 function. The cs_straddr takes a COMSTACK handle as argument, so this
3500 function must be used after cs_create and before bind/connect.
3501 This function is thread safe.
3503 Moved test server to 'ztest' directory - generic server code still
3504 in 'server' directory.
3506 Made prefix query (pquery.c) utility thread safe.
3508 Added new function modifier YAZ_EXPORT to 'export' public DLL
3509 functions when using windows (see include/yconfig.h).
3511 Added definitions to the OID database (util/oid.c) (RVDM).
3513 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3515 Added call to ccl_rpn_delete in client program.
3517 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3518 release of RPN structure.
3520 Added support for C++, headers uses extern "C" for public definitions.
3521 With input from RVDM.
3523 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3524 Thanks to Ronald van der Meer (RVDM).
3526 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3528 Added support for private extensions to the OID database
3529 (oid_setprivateoids()). Thanks to RVDM.
3531 Added optional, physical ANY (key replication)
3533 Fixed null-reference problem in GRS-1 output filter.
3535 Proximity operator added to Prefix Query Format (PQF).
3537 In test client command "base" accepts multiple databases.
3539 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3543 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3545 Smallish bug-fixes in the new encoders/decoders (explain).
3547 Bug fixed in DeleteRequest.
3549 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3551 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3553 Added SOIF syntax (using private OID for now) to retrieval module and client.
3555 Added Update extended service.
3557 Added SearchResult-1 additional info structure.
3559 Added optional CCL (ISO8777) interpreter as separate module. Available
3562 --- 1.2 1996/6/10 (1st anniversary release)
3564 Added Summary record syntax. Lightly tested.
3566 Added OPAC record syntax. Untested.
3568 Added ResourceReport service encoders/decoders. Untested.
3570 Fixed bug in z_Unit - wrong tagging on unitSystem.
3572 Fixed bug in the DiagRecs decoder.
3574 Added options for max PDU size and session timeout to frontend-server.
3576 Added documentation of query-language parsers and other supporting utilities.
3578 [frontend-server] Added Attribute set to the bend_scanrequest API.
3580 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3581 surrogate diagnostics were generated.
3583 [retrieval] Allow multiple local values for attribute.
3585 [retrieval] Allow multiple attributes per element in .abs files. index type.
3587 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3589 --- 1.1pl2 1996/4/10
3591 Minor changes, mostly specific to Zebra's requirements (retrieval)
3595 Repaired bug in frontend server when running multiple listening
3596 endpoints in dynamic mode.
3598 z_External() now won't break if a known, ASN.1 value comes encapsulated
3599 in an octet-string. The value will pass through unmodified in an Odr_oct.
3601 Added a bit of code to the demo client to decode & display
3602 ASN.1-structured records represented in the octet-aligned branch of
3603 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3605 Added z_ext_getentbyref() to the ASN module. Doc updated.
3607 * Completed the SCAN definition in the ASN module. This may break SCAN
3608 code based on older YAZ-versions at compile-time. The fix is easy -
3611 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3612 under the SCAN definition. Remember to initialize this, server-people.
3614 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3615 that this does not extend to ODR and ASN.
3617 Comstack allows insertion of established socket (primarily for
3618 inetd-operation of servers). Doc updated.
3620 Front-end server can now start from the inetd in TCP mode. Doc
3623 --- 1.0pl4 1996/1/24
3627 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3628 the rank and record number.
3630 Adjustments to the frontend server.
3632 Fixed diagnostic BER dumper. It ignored the file argument.
3636 Various changes to retrieval module.
3638 Changed the union discriminators of the protocol files from enums to
3639 ints paired with #defines.
3641 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3644 *Changed operator in the RPN structure to 'roperator', again to avoid a
3647 Fixed problems in Explain decoders/encoders.
3649 --- 1.0pl2 1995/12/6
3651 Memory bug in log module fixed.
3653 --- 1.0pl1 1995/12/5
3655 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3657 Bug in Explain DatabaseInfo module fixed.
3659 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3663 The shift to v1.0 signals that we now consider the *core* functionality
3664 of YAZ reasonably stable (the core being more or less equivalent to
3665 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3666 tested (Explain not at all - though that will happen soonish).
3668 Minor changes to code to support Windows port.
3670 Various minor changes after we're getting to use GRS-1 & co. more.
3672 Added Espec-1 format.
3674 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3675 of the protocol and it cannot be selected when encoding (maps into 'string'
3676 when decoding). Needed to talk to some servers.
3678 Demo client can request simple element set names.
3680 Added Diagnostic Format encoders/decoders.
3682 Added simple Close handling to frontend server (no hooks for resource
3683 reporting yet), and demonstration client.
3685 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3687 --- 1.0b3 1995/08/24
3689 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3690 handled incorrectly when records were requested in the searchResponse. This
3691 will only affect you if you use the frontend-server.
3693 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3694 Test-client will ask for and print GRS1. Ztest will return dummy records
3697 Added Explain encoders/decoders to the service-level API. Untested.
3699 Added Extended Services: Item Order encoders and decoders to the Service-
3700 level API. Untested. We could use a recent copy of the pertinent bits
3701 of the ILL protocol to add those bits.
3703 Added diagnostic format 1 encoders/decoders to the service-level API.
3706 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3707 odr_cons.c, which causes a more correct output.
3709 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3710 was always set to 0 when no records were requested in the searchRequest.
3712 * Added better external-handling. This shouldn't harm old code that
3713 *encodes* externals. It can break code that looks for a
3714 'single-ASN1-type' representation, since those types that are known
3715 are now decoded immediately. Look at the SUTRS sample code in
3716 seshigh.c and client.c. Documentation updated.
3718 Handling of structured records in bend_fetchresponse. Length -1 marks
3719 structured record, type is deduced from format field.
3721 --- 1.0b2 1995/06/27
3722 Fairly quick maintenance release to add SUTRS support.
3724 Fixed handling of SUTRS records in the demonstration client.
3726 * Added format field to the bend_fetchrequest and bend_fetchresponce
3727 structures of the backend API (frontend server). When the record is
3728 returned, the value of the format field is mapped to an OID. The
3729 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3730 of the record. The special value VAL_NONE in the bend_request means
3731 that no specific format was requested by the client. Documentation
3732 updated accordingly. Test server (ztest) will return a fixed dummy
3733 SUTRS record if your client requests SUTRS.
3735 Documentation updated accordingly.
3737 You can now set external libraries and RANLIB support in the top-level
3741 First public release.
