3 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
4 and facets. Ensure recordData and recordSchema are always present in
5 record element, because they are required.
7 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
10 Simplify in a lot of places using odr_strdupn.
12 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
16 Increase various buffers in GFS's statserv_options_block
17 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
18 This change makes many type-casts redundant, and, thus simplifies code.
20 Remove last bits of WAIS support.
22 Remove member 'size' from Odr_oct.
24 Slim down the public part of 'struct odr'. Most elements are not part
25 of struct Odr_private.
27 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
28 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
29 In particular facets are supported in both client - and server side.
30 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
31 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
32 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
33 both request/response). This is what a search handler in the GFS
34 will see (regardless of whether operating in SRU mode or Z39.50).
36 Changes to the srw.h (SRU/Solr) definitions include:
37 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
38 (char*), which replace union query and query_type (int). This is because
39 SRU 2.0 supports a queryType parameter. This also means that, to carry
40 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
41 x-pquery=PQFstring (extention parameter). The extension parameter
43 - New element, packing, that has information about SRU
44 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
46 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
48 New element, packing, in Z_SRW_explainRequest.
50 New elements in Z_SRW_scanRequest, queryType and scanClause.
51 These replace query_type and scanClase untion. This is similar to what
56 GFS: log when closing down - at least SIGTERM YAZ-684
57 Also change formatting WRT PID logging a bit.
59 Improve display of MARC records with multi-byte subfield IDs YAZ-695
60 In some rare cases subfield identifiers are multi-byte characters.
61 This will try to deterime length of those and split accordingly.
62 This affects display in line mode as MARCXML/MarcXchange. The encoding
63 of ISO2709 is the same.
65 Change inp argument to const for yaz_read_UTF8_char.
67 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
69 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
71 Better check of marc leader info YAZ-691
72 Problem is that some systems generate MARCXML/MarcXchange with
73 funny headers. These will not work if encoded as ISO2709.
74 Some tests produce new output, due to updated warning messages
76 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
78 yaz-client: display MAB records YAZ-689.
79 Thanks for Heiko Jansen for this patch.
81 New utility z_get_HTTP_Response_server which allows both HTTP server name
82 and HTTP server URL to be given in response.
84 Debian: do not depend on obs tcl8.3.
86 Debian: do not depend on obs libicu36-dev.
90 GFS: pass additionalSearchInfo to search memeber search_input if
91 given. Otherwise pass otherInfo. Request for facets and other search
92 related things will be passed there in future versions of YAZ.
94 New ZOOM setting, authenticationMode, which allows authentication
95 paramters to be encoded in the URL rather than via HTTP Basic auth.
98 rpn2solr: fix nested AND/OR handling. YAZ-685
100 Add comparison routines for some Z-types, such as NamePlusRecord,
101 RPNQuery, Query, RecordComposition and OtherInformation.
103 --- 4.2.67 2013/09/19
105 Don't decode MAB as MARC. Just like we don't attempt to decode
106 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
108 CCL: allow quoted terms for date ranges. YAZ-681
110 Introduce ccl_parser_qual_search. This function makes old function
111 ccl_qual_search, from YAZ 2, available again.
113 Add yaz_facet_list_to_wrbuf. YAZ-683
115 --- 4.2.66 2013/09/11
117 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
118 schema was given for search. YAZ-675
120 Add Solr date range searches. YAZ-621
122 --- 4.2.65 2013/08/22
124 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
126 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
128 ISO2709/MARC parse most octet aligned records; not just those that
129 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
130 MARC parse more records instead of just dumping as is. YAZ-670
132 ZOOM: proper caching for variations of record schema. YAZ-671
134 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
136 --- 4.2.63 2013/07/17
140 --- 4.2.62 2013/07/11
142 New utility z_get_HTTP_Response_details - an extended version of
145 New utility yaz_url_get_error which returns error message of last
146 failed yaz_url_exec call.
148 yaz-url and url functions: allow max HTTP redirects to be controlled.
150 New functions yaz_file_glob2, yaz_xml_include_glob.
151 These functions takes a flags parameter, which, for now only controls
152 whether to fail inclusion of a non-existing file (without glob
153 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
155 --- 4.2.61 2013/06/20
157 For MARC XML parsing, allow record without leader. A fake/default leader
158 is inserted and a warning is tagged with the record.
160 ICU: fix leak in in icu_iter_get_org_info.
162 --- 4.2.60 2013/06/14
164 ICU: fix bug in icu_iter_get_org_info (un-init variable).
166 --- 4.2.59 2013/06/11
168 Implement z_HTTP_header_remove.
170 --- 4.2.58 2013/06/11
172 ICU: Disallow 0 ptrs for some ICU string utilities.
174 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
175 returns original tokens (before normalization).
177 CCL: avoid z39.58/regex truncation when not needed. Apply only the
178 conversion of those masks, when absolutely necessary.
180 CCL: configurable masking character - @mask. Default masking character
183 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
184 full response anyway, so a Transfer-Encoding header will obstruct the
187 --- 4.2.57 2013/05/15
189 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
190 picking a socket. Problem is that some systems has IPV6 support, but
191 we can't create sockets for them, so we pick AF_UNSPEC first.
193 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
194 use content_len to determine resulting Content-Length in HTTP response
195 and NOT Content-Length supplied in headers by user.
197 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
198 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
200 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
203 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
204 with big endian and unsigned char (by default).
206 --- 4.2.56 2013/04/26
208 Fix yaz-client connect (crash in 4.2.55).
210 --- 4.2.55 2013/04/26
212 Fix proxy/host problem for ZOOM that could occur if unix sockets
215 New Debian package libyaz4-dbg.
217 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
218 differently in tcpip_close.
220 --- 4.2.54 2013/04/17
222 Windows installer of YAZ includes YAZ4J as a component.
224 CQL: allow "extra terms" again, by default. Thus, the CQL parser
225 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
226 and earlier. CQL parser may operate in strict mode where queries
227 not conforming to the standard BNF are rejected (syntax error).
228 Whether the CQL parser operates in strict mode is controlled with
229 cql_parser_strict . Strict mode enabled with option -S for utilities
230 cql2pqf and cql2xcql .
232 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
234 --- 4.2.53 2013/04/10
236 New charset, MARC-8c, which is like MARC-8 but allows control characters
237 0x01 through 0x1F, except ESC to be passed through verbatim.
239 Fix a problem with duplicate sub field character in MARC output. Problem
240 happened only when output was MARC-8 encoded.
242 --- 4.2.52 2013/04/03
244 yaz-ztest: Use hash for fake hit count. Before, random number was used.
245 This is problematic for unit tests using yaz-ztest. This patch also makes
246 a hash for CQL queries. For RPN, any term with a leading digit will be
247 treated as pseudu hit count (to force any particular hit count by a client).
249 yaz-ztest: return unique MARC dummy records. Beyond record offset
250 24, the author surname is patched with offset to make all records
253 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
254 on system wide default (/proc/sys/net/ipv6/bindv6only).
255 @4 binds to IPV4 only. @6 binds to IPV6 only.
257 Update CQL API documentation a bit
259 CQL: don't accept extra terms for queries. Makes the CQL parser
260 stricly conformant to the standard.
262 --- 4.2.51 2013/02/12
264 GFS: scan handler gets extra_args from request and may return extra
265 response data . That's for SRU only.
267 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
269 --- 4.2.50 2013/01/30
271 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
273 OPACXML: sync spelling of availabilityDate in XML to that of Schema
274 opaxxml.xsd. The schema had the correct spelling of this member always.
275 The ASN.1 was mis-spelled and still is (API change) - we are
276 not changing this. However, the OPAC to XML conversion had yet
279 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
282 New function, z_ext_record_oid_nmem, which is similar to
283 z_ext_record_oid but takes NMEM rather than ODR
285 --- 4.2.49 2013/01/18
287 ICU: New conversion element 'join' which joins tokens into one
288 with a custom character given by rule attribute.
290 --- 4.2.48 2013/01/10
292 New GFS search member: present_number. This is a hint to the
293 search handler how many records are going to be fetched immediately
294 following search. There's no guarantee that it's going to be the case,
295 since it depends on hit count (for Z39.50 piggyback) and whether errors
298 Make a few functions static (private). The functions getbyte_stream,
299 ungetbyte_stream and yaz_gets are now private. They were never declared
302 yaz-marcdump: exit(5) for serious decoding errors
304 ISO2709 decoding: be more picky WRT header
306 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
307 was only used as to indicate that next-result-set-position should be
309 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
310 Based on patch from Ashley Sanders.
312 Make some functions static/private in PQF parsing. Those functions were
313 never declared in a public header and so should not be in use by
314 applications based on YAZ.
316 --- 4.2.47 2012/11/23
318 ZOOM: special options to control APDU logging.
319 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
320 logging of APDUs until "saveAPDU" option is set again. If logging is
321 already enabled the effect is that current APDU buffer is cleared.
322 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
323 logging (default behavior on new connection).
324 The APDUs sent/received can be obtained by using
325 Using ZOOM_connection_option_get(c, "APDU") or
326 ZOOM_connection_option_getl(c, "APDU", &l).
328 GFS: relay implementation_version from backend
329 From 3.0.40 and later, implementation_version from backend was
330 not used in init response at all.
332 --- 4.2.46 2012/11/15
334 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
335 mode at all. Probably never did.
337 Make a new version of ztest.pem that, at least, is not expired.
339 --- 4.2.45 2012/11/13
341 Fix description of CCL directive 'case'.
343 More tight checking of form arguments (yaz_uri_to_array). Makes
344 YAZ better at rejecting big and/or bad POSTs.
346 SRU decoding does not report more than up to 10 invalid arguments.
348 rpn2cql: less quotes in generated terms. Semantics unchanged, but
349 it's prettier this way.
351 --- 4.2.44 2012/10/25
353 New utility yaz_decode_init_diag. Defined in proto.h.
355 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
356 given for unix local socket.
357 The COMSTACK string for doing so is:
360 unix:/myfile:tcp:localhost:9999/mybase
361 unix:/myfile:localhost:9999/mybase
362 unix:/myfile:http://fakehost/mybase
364 debian: Use dpkg-buildflags in build process.
366 --- 4.2.43 2012/10/19
368 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
369 global's SRU service uses a recordPosition scheme starting from zero.
370 First record's position should be one
371 according to the standard.
373 --- 4.2.42 2012/10/18
375 Allow more namespaces for SRU. This is to allow, for example, an
376 incorrect namespace returned from server
377 http://services.igi-global.com/sru .
379 Minor fixes for compilation on Windows.
381 --- 4.2.41 2012/10/11
383 daemon: log total number of bad signals from child on stop so that it
384 is more easy to spot problems with child worker processes.
386 retrieval: empty backend name attribute omits element set
387 from being used in retrieval.
389 --- 4.2.40 2012/10/04
391 Implement Solr sort strategy "solr", similar to sru11 sorting.
392 This will implement the correct parameters on Solr requst to do
395 --- 4.2.39 2012/09/28
397 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
400 MARC: Extra/missing indicator handled for MARCXML.
401 The indicator length is given in header and is the same for the
402 whole record. If attributes ind1, ind2 are missing, then content
403 character defaults to blank. Extra indicator attributes (beyond)
404 indicator length are treated as an error.
406 Reformat: delete trailing whitespace
408 --- 4.2.38 2012/09/17
410 MARC: fix non-ASCII characters for leader. This is to ensure we can
411 generate XML in UTF-8.
413 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
414 in one node with structure word.
416 --- 4.2.37 2012/09/04
418 yaz-json-parse: JSON output may be pretty printed by using option
421 Increase default value of max message for Z39.50 Init for GFS, ZOOM
422 and yaz-client. Old value was 1 MB. New value is 64 MB.
424 --- 4.2.36 2012/08/22
426 yaz-client: don't display bogus records from SRU servers. Some SRU servers
427 return more records than given by *maximumRecords*. Skipping those in
430 record_render: simplify buffer return handling and fix at least one bad
431 memory reference, that broke the test_embed_record sometimes.
433 Allow http://user:pass@host notation for yaz_url_exec.
435 zoomsh: allow shell command to be executed. Via the system(3) call.
437 yaz_poll: Allow num_fds == 0
439 yaz-client: fix bad encoding of "itemorder item". The itemorder
440 item <no> - command forgot to use length of encoded Item Request
441 package. Error present since YAZ 3.
443 yaz-ztest: fix bad usage of session handle. Bug was introduced when
444 result sets were saved (271a9c83).
446 SRU recordPacking: guess record packing in response rather than looking
447 at the recordPacking element which, OF COURSE, changed semantics in SRU
450 Decode SRU 2.0 responses. The official namespace for responses, according
451 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
452 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
453 nature.com's server, however, usee namespace
454 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
455 we are now using a glob-expr to match up the namespace. ZOOM C and
456 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
457 I can not find a single real example showing the "real" namespace in
458 the documentation from OASIS. The namespace for requests is different
459 from responses, but this is not added to YAZ yet, when we don't encode
462 --- 4.2.35 2012/06/26
464 zoom/record_render: add support for Base64 decoding fo MARC records
465 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
466 which will decode base64 + ISO2709 marc-8 encoded material from text node
469 --- 4.2.34 2012/06/07
471 Add missing definitions ZOOM_resultset_get_facet_field_by_index
472 and ZOOM_resultset_facets_names.
474 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
477 Change APDU dump printing to avoid long leading blanks. For levels 16
478 or larger the level is shown and the indentation is truncated but
479 recursed with modula 8. This makes it still reasonable easy to read
480 - even for nested BER dumps.
482 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
483 return 0 (incomplete package) in case where the BER package was
484 considered too nested (return value of -2).
486 dumpber: lines of level 15 are not indented further. Two spaces per
487 indentation; indentation 15 or more is indented to a fixed indentation
488 and augmented with a level=<no> indication.
490 zoomsh: increase max size of command+args
492 GFS: No limit in RPN buf size in CQL to RPN conversion.
494 --- 4.2.33 2012/05/09
496 New function for daemon utility, yaz_daemon_stop .
498 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
500 --- 4.2.32 2012/04/25
502 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
503 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
505 --- 4.2.31 2012/04/23
507 YAZ daemon utility relays SIGUSR1 to child process.
509 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
510 would result in en empty database list - which in turn would result in
511 encoding failure for search.
513 Fix reading beyond string in yaz_sort_spec.
515 --- 4.2.30 2012/04/11
517 Add two new SRU diagnostics:
518 236: Access to specified database denied
519 1015: Init/AC: Maximum number of simultaneous sessions for Userid
521 Document the very useful ZOOM-C option "apdulog".
523 CQL to RPN: term may be passed through verbatim. This is enabled with
524 truncation.cql . The assumption being that the term is already CQL.
526 --- 4.2.29 2012/03/20
528 record_conv: leader spec may be given for marc element.
529 The leader spec is given as attribute leaderspec for element marc.
530 For example to convert a MARC21 record from MARC-8 to UTF-8:
531 <marc inputformat="marc" outputformat="marc"
532 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
534 record_conv: allow user-XSLT params. For example:
535 <xslt stylesheet="MARC21slim2DC.xsl">
536 <param name="myparameter" value="myvalue"/>
537 <param name="otherparameter" value="othervalue"/>
540 record_conv: fix error handling for missing marc charsets.
542 CQL: fix extra terms in wrong order.
544 --- 4.2.28 2012/03/06
546 record_conv: modify new API for conversion types. The conversion types
547 may be passed in new functions yaz_record_conv_configure_t and
548 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
550 Avoid mixed statement/variable declare; fixes compilation with Visual
553 --- 4.2.27 2012/02/28
555 Add non-standard SRU diagnostic: 235: "Database does not exist".
556 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
557 Update SRU to Bib-1 diagnostic maps accordingly.
559 CCL: add two new diagnostics for unsupported masking. The new
560 diagnostics are: "Embedded truncation not supported" and
561 "Single charcacter mask not supported".
563 --- 4.2.26 2012/02/23
565 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
567 --- 4.2.25 2012/01/11
569 Build YAZ for Ubuntu Oneiric.
571 CCL: allow parantheses for proximity operands. For example CCL query
572 (a) % (b) is now allowed.
574 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
575 marked dead, rather then being destroyed. If not, the session memory is
576 being free'd before the search/scan handler is finished. Also destroy
577 'request' memory in request_release rather than in various places,
578 which resulted in leaks from time to time.
580 --- 4.2.24 2011/12/21
582 cql_sortby_to_sortkeys: honor sort prefix.
584 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
585 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
586 The rpn2cql family of functions now always returns quoted CQL terms.
588 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
590 --- 4.2.23 2011/12/15
592 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
593 sequence is treated as one. For example, &&a=b&&&c& is identical to
596 --- 4.2.22 2011/12/05
598 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
599 APDUs for a connection to a WRBUF.
601 --- 4.2.21 2011/11/23
603 Fix cql_sortby_to_sortkeys. Completely broken before.
605 Make CCL's @truncation work again.
607 --- 4.2.20 2011/11/09
609 New ZOOM connection setting: tproxy. It's like proxy, but does not
610 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
611 to set resolved address + port for a connection outside ZOOM itself.
613 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
615 --- 4.2.19 2011/11/07
617 Fix uninitialized variable in Solr spell support (could cause SEGV
618 for SRU response decoding).
620 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
621 back-end's addinfo through into the ZOOM response addinfo.
623 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
624 they are separated by a colon and a space rather than simply
627 --- 4.2.18 2011/10/28
629 Add support for Solr spell-checking/suggestions through ZOOM.
630 If a Solr target has been configured correctly for spelling-checking
631 and suggestions, these will now be returned on the ResultSet option
632 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
634 --- 4.2.17 2011/09/28
636 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
637 with a flag whether to substitute escape sequences or not.
639 --- 4.2.16 2011/09/22
641 Fix nmem_strsplit_escape to substitute escape char properly.
643 New option for zoomsh -e , which makes it abort on first error and
644 return process exit code to indicate success/failure.
646 YAZ options utility supports special option -- which makes all it treat
647 all following arguments as non-options.
649 --- 4.2.15 2011/09/16
651 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
652 searched if absolute filename is given.
654 Fix conv_xslt() error-reporting when stylesheet is not found.
655 (The value of fullpath is meaningless in this situation.)
657 --- 4.2.14 2011/09/07
659 Fix problem in CQL sort node creation: un-initialized memory.
661 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
662 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
663 CQL sortby depending on whether Type-1 or CQL is actually sent to the
666 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
667 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
669 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
670 will make it possible to use both single-character mask (#) and wildcard (?)
671 in CCL . Throw diagnostic for left truncation because that is not supported
674 --- 4.2.13 2011/09/01
676 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
677 cases using escapes (\-sequences) and masking.
679 PQF parse fix: A trailing backslash followed by end-of-string (\0)
680 would result in a read one byte beyond string.
682 rpn2ccl may use Z39.50 masking for terms (t=z).
684 ICU check fix. Don't include library -lCrun on Solaris, unless present.
686 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
687 not --cppflags (which seeems like an error in icu-config).
689 --- 4.2.12 2011/08/27 RPM package only
691 cql2ccl: fix conversion of terms: operator characters were not
694 --- 4.2.11 2011/08/25 RPM package only
696 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
697 CCL parser will map both # and ? to their regular expression
698 quivalents (. and .*).
700 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
701 of reserved CQL characters.
703 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
704 is, so that they are passed through.
706 --- 4.2.10 2011/08/24
708 ZOOM SRU mode: more aggressive re-connect.
710 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
711 made available as a utility function, declared in <yaz/logrpn.h>
713 rpn2cql_structure() supports proximity nodes (except that the Type-1
714 proximity node's "exclusion" binary is ignored, as there is no way to
715 express that in CQL). Fixes bug #4564.
719 Fix SEGV that could occur if set command of zoomsh was given without
720 value (2nd argument).
722 Fix SEGV that could occur if unsupported transport was given for
723 COMSTACK - say https (when SSL was unavailable).
725 Build yaz-url on Windows too.
729 New utility to get web content. Header is url.h. A command line tool
730 yaz-url is part of the distribution and packages.
732 Fixes for SSL COMSTACK (when gnutls is in use).
734 New functions yaz_base64{encode,decode}. Header is base64.h.
738 ZOOM C includes HTTP response buffer as additional info if it fails
739 to decode the SRU response.
741 Make wrbuf_json_puts available.
745 zoom: throw diagnostic for invalid value for option "sru". Before a
746 bad SRU request was sent.
748 Adding new utility wrbuf_vp_puts.
750 Add cclxmlconfig.obj to win/makefile. It was missing completely.
754 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
755 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
756 redirect was used at the same time.
758 MARC line mode decoding: be less picky about length given - first
759 5 digits of header that is.
761 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
763 Changes to decoding of SRU records: a record with recordPacking=xml is
764 modified with a new root element <yaz_record> if the recordData contains
765 multiple children elements. This is to make the record XML parseable
768 RPN to Solr conversion: encode special characters.
770 Generic Frontend Server: fix uinitialized member, stepSize.
774 Fix a bug in SRU decoding of records.. The database records stored
775 had un-initialized memory, but it would only be seen with yaz_record_render
776 and type_spec="ext" .
778 Fix a bug in ccl_qual_dup introduced in 4.2.3.
782 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
786 Add new utilities to convert from CQL to CCL . These utilities have
787 prefix cql_to_ccl defined in cql.h.
789 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
790 lead to memory heap corruptions when ICU utilities were in use.
794 Make compilation work without Libxml2.
796 yaz-client: remove redundant blanks in display of searchResult-1 term
801 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
802 resulting CQL node (tree) in a new node CQL_NODE_SORT.
804 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
805 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
806 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
807 Note that the CQL sortby spec is only converted when the GFS is already
808 converting from CQL to RPN (cql2rpn element).
810 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
811 specify whether to collapse delimitors or not. The existing nmem_strsplit
812 do collapse (collapse parameter = 1).
814 Windows installer: For NSIS, set InstallDir depending on x86/x64.
816 Rename internal func yaz_use_attribute_create. While non-static, this
817 function is not declared in a public header.
821 Add -lCrun when linking with ICU on Solaris.
823 More quicks character set conversions for OPAC records.
827 fix problem with record_render: records were converted (character set
828 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
832 SRU: add methods for handling DADS SRU-proxy facets.
834 Separate OPAC record character set for ZOOM_record. yaz_record_render
835 allows a character set given as charset=from/opacfrom,to where 'from' is
836 the character set of a bibliographic record, 'opacfrom' is character set
837 of OPAC record and 'to' is the target character set.
841 yaz-client: show may XML format records. Command show followed by 'format'
842 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
845 src/stemmer.c: Avoid using unnamed union. It is not supported by some
848 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
851 Update yaz.spec to operate on both SLES11 / Centos 5.5.
853 RPM: Release includes 'indexdata' name. Use indexdata in release name so
854 this package can be distinguished from other vendors.
856 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
857 as determined by configure
859 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
861 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
862 returns no error and no record, the present request is considered
863 partial (only a subset of the records could be returned by backend), and
864 so it is appropriate to set Present Status to partial-4.
868 Move yaz-config man pages to section 1.
870 More documentation about Solr.
872 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
873 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
874 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
875 peers on some Linux systems. However, in general that does not work
876 so YAZ can not rely on that to work. Debian changed behavior in this
877 respect from Debian lenny to Debian squeeze (still testing as of Oct
879 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
881 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
885 Fix yaz-config output: echo_source not set correctly by configure.
889 Solr Web Service support for yaz-client and ZOOM.
891 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
893 --- 4.0.12 2010/08/17
895 Z39.50 facet support. Facet specifications are passed for search in
896 other-information with ASN.1 as defined in facet.asn and OID
897 .10.1000.81.5 . Facets are expressed as an Attribute list as known
898 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
899 3 is limit (number of entries to get in response). yaz-ztest returns
900 dummy facets if a client asks for them.
902 --- 4.0.11 2010/07/09
904 CCL fixes: bug 2895 and bug 3539.
906 GR1-display: add comma in display - was removed by mistake in
909 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
911 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
913 --- 4.0.10 2010/06/18
915 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
916 result set from a connection. The result set will be on its own
917 thereafter; no operations on it will perform retrievals from a target.
918 Only cached copies are returned.
920 ZOOM C:fix case for HTTP servers responding with Connection:close.
921 Ensure that if there is a current task it is resumed (like fetching
922 more records in a result set) . Bug #3484.
924 PQF parser: use odr_atoi for Odr_int (not atoi)
926 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
927 values that contain any non-digits are treated as string attributes
928 (previously decoding only checked for leading character ([0-9]). PQF
929 encoding: attribute string values are not surrounded by double-quotes.
933 New utility for managing threads - thread_create.h.
935 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
936 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
937 but YAZ' implementation do.
939 Fixes for yaz_cond-functions on Windows 7.
941 DLL export more symbols.
943 zoomsh: show record do NOT render opac.
945 Remove *.la files from Debian and RPM packages.
949 Debian package libyaz-dev depends on libgnutls-dev again (was
950 removed in YAZ 4.0.6, but due to Libtool it is still needed
951 even though yaz-config do not list libgnutls libs).
953 ZOOM: Use only one WRBUF for returning string results for
954 ZOOM_resultset. Reduces memory usage for ZOOM in general.
956 ZOOM: ZOOM_connection do not use a shared pointer to
957 ZOOM_resultset after ZOOM_resultset is destructed by
958 user. Reverts to YAZ 4.0.4 behavior.
962 record-conv: fix problem with at least one XSL conversion -
963 due to probably incorrect usage of XML XSL documents.
967 Fix yaz-config for static mode and the use of SSL (gnutls).
971 Forward decl timeval struct in mutex.h and gettimeofday.h.
973 yaz-config: fix 'static' mode linking.
977 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
978 are wrappers for pthreads or Windows. For Windows these are put in
979 a separate DLL: yaz_cond4.
981 libyaz.la (whole source) is compiled with thread. If thread support
982 is enabled enabled, all source of YAZ is compiled with treading support.
983 This allows core utilities such as yaz_log to use thread facilities.
984 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
985 thread utilities. This commit moves mutex utilities (mutex.c) from
986 libyaz_server.la to libyaz.la.
988 yaz-json-parse displays leading text until error.
992 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
993 patch from Giannis Kosmas.
995 SRU: no longer URL encode SRU database. The URL for an SRU server is
996 a URL and such is alreeady encoded - at least when given with leading
997 http:// or https://. This reverts behavior to YAZ 3.0.50.
999 Support for new MARC XML notation TurboMARC which like MARCXML is a
1000 complete representation of MARC/ISO2709.. This one, however, is more
1001 compact and allows for faster processing with XSLT. TurboMARC can be
1002 used in the marcdisp.h API, from the yaz-marcdump utility and from
1005 yaz-ztest can be configured - via the database - to perform certain
1006 delays when it performs operations search, present and single record
1007 fetch. This allows testers to make yaz-ztest act as a real or even slow
1008 Z39.50 server. Refer to the yaz-ztest man pages for details.
1010 --- 4.0.2 2010/03/09
1012 wrbuf_destroy allows NULL WRBUF passed to it.
1014 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1016 Add ZOOM_connection_close.
1018 No fixed size buffers for ZOOM shell - bug #3257.
1020 tstodr: make it work on s390 platform.
1022 New icu iterator-functions. The new icu_iter-functions makes it possible
1023 to use ICU chains from many threads.
1025 yaz-client: better syntax check for show command.
1027 --- 4.0.1 2010/01/26
1029 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1032 New simple local-file XML include facility which allows file glob-patterns.
1033 Refer to yaz/xml_include.h.
1035 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1038 ZOOM_record_get supports new parameter "format" which makes it format XML
1041 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1042 JSONText in ECMA-262) is JSONValue, not JSONObject.
1044 --- 4.0.0 2010/01/20
1046 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1047 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1049 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1050 POSIX/Unix builds .so with major version 4.
1052 Remove old LOG_-defines from log.h. They have been obsolete and
1053 undefined by default for the last 5 years.
1055 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1057 GFS: Remove socket (int *fd) from search_rr handler. The socket
1058 descriptor ptr is a facility that allowed a search handler to supply
1059 a socket which would serve as a callback - when search was complete.
1060 This facility has now been in use for years.
1062 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1063 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1064 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1065 returns 'const char *' rather than 'char *. The returned string is
1066 read-only and should not be modified by applications. COMSTACK cs_close is
1067 now a void function - it no longer returns int. No applications check for
1068 the value and the implementations has always returned 0.
1070 ZOOM: use size_t for scan hit counts and str size. Functions
1071 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1072 occ (hit count) and len (string length) are now of type size_t pointer
1073 rather than int pointer. This is to be able to represent large hit counts
1074 and to also just to use the proper type for string length (strlen result).
1076 New JSON parser. Refer to include/yaz/json.h .
1078 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1079 Used to be int in some cases. Many wrbuf_-functions used to return an int
1080 indicating some length.. These return values were never used. And so they
1083 ODR: odr_malloc, odr_total now takes size_t for size.
1085 clone_z_type: fix leak; occurred for encoding failures.
1087 --- 3.0.52 2009/12/03
1089 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1090 bug was introduced in 3.0.51.
1092 --- 3.0.51 2009/12/02
1094 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1096 tcpip comstack: fix leak for getaddrinfo.
1098 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1099 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1100 Decoding of SRU "path" database is performed by private function
1101 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1102 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1104 yaz-client: honor base command for SRU. Change when database setting
1105 is applied for SRU and ensure it is kept when a connection is reset.
1106 Change also the way errors are displayed or SRU (decoding of packages).
1108 --- 3.0.50 2009/11/02
1110 Add support for extra request / response data for SRU codecs and GFS.
1111 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1112 for extra data response buffer and length. For the GFS, both request
1113 and response data (XML) is carried in extra_args and extra_response_data
1114 for the search handler. Patch by Ko van der Sloot.
1116 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1117 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1118 10010). This fixes bug #2113.
1120 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1121 cmdfile included a 'quit' command that would result in a memory violation.
1123 --- 3.0.49 2009/10/01
1125 Make a number of functions defined in xmlquery.c static. These have
1126 never been declared in a public header file (yaz/xmlquery.h) and was
1127 made public by mistake.
1129 Improve speed of character conversions (iconv utilities). This makes
1130 conversions from MARC-8 faster.
1132 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1133 unless type desired is "raw". This will prevent type "xml" from
1134 returning ISO2709 .. Which obviously can not be XML parsed.
1136 Fix memory leak in ZOOM that would occur if option apdulog was used
1137 on a re-used connection.
1139 Frontend server logs HTTP requests.
1141 Frontend server now sends Z39.50 close when it times out (sesssion has
1142 been idle for too long). Versions 2.0.30 and earlier also sent close.
1143 But due to a mistake this was disabled in all versions after that, i.e.
1144 the server would just close the socket immediately.
1146 yaz-client emits a better message when receiving an unrecognised
1147 userInformationField.
1149 Skip zero-length subfields when decoding ISO2709. This rare case happens
1150 if a record has two FS characters in a sequence. Without this patch
1151 there would be a reference beyond char array in using_code_len fragments
1154 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1156 --- 3.0.48 2009/08/28
1158 The show command offered by the zoomsh command now takes a 3d optional
1159 parameter type which is what is passed to ZOOM_record. If the type
1160 argument is omitted, "render" is used.
1162 RPN to CQL conv may use USE string attributes (bug #2978).
1164 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1166 --- 3.0.47 2009/07/08
1168 Function yaz_xml2query allows a diagnostic element in the PQF XML
1169 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1170 code and additional info respectively.
1172 The BER BOOLEAN is now the integral type Odr_bool which still happens
1173 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1174 typedef'd to Odr_int. This is still an integral 'int', but it may be
1175 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1176 ASN-1 compiler as well as programs has been updated to use the new types.
1178 --- 3.0.46 2009/06/08
1180 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1181 only the bibliographic record was rendered. For type=opac, an OPAC
1182 record is only returned if it is present.
1184 iconv: small fix for encoding of advancegreek.
1186 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1188 yaz-client: option auto_reconnect=on really reconnects.
1190 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1192 server: avoid null ptr ref for for yaz_poll errors.
1194 build: fix RPM build for RHEL 5.3.
1196 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1198 --- 3.0.45 2009/03/31
1200 Fixed bug #2709: TCP connect returns Invalid argument.
1202 Fixed compilation for mingw.
1204 Honor charset for raw records (ZOOM_record_get).
1206 Fixed use of errno for threaded mode that was seen on Solaris 10.
1208 Fixed argument passing with blanks in value for Windows Service.
1210 Disable YAZ' own log rotate by default (no 1 GB limit).
1211 The variable l_max_size which specifies the log file limit is set to 0
1212 (DISABLED): This is due to the fact that YAZ is most often deployed using
1213 logrotate. Also YAZ can not perform log rotate because of unsufficient
1214 permissions (setuid).
1216 --- 3.0.44 2009/02/17
1218 List supported encodings in man page for yaz-iconv.
1220 Fixed missing SSL libs for --libs output
1222 Re-established OID record syntax application-xml. Nobody should use it
1223 but we don't want to change soname because of this symbol being absent.
1225 --- 3.0.42 2009/02/02
1227 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1229 Added member named_result_sets for init handler struct for the GFS. This
1230 allows a server to disable named result sets.
1232 Removed OID record syntax application-xml.
1234 Added support for rule-based transliterator for ICU wrapper of YAZ.
1236 Fixed bug #1902: yaz-icu XML output.
1238 Make YAZ checks Emacs friendly.
1240 BITSTRING value shows value. Bug #2346.
1242 ISO2709 decoding: skip control characters from indicator data.
1244 Omit sort key by default in yaz-icu's output.
1246 Allow combined single char options (again) for YAZ' options function.
1248 Utility yaz-marcdump got option to display YAZ version (-V).
1250 Allow YAZ to use ICU 3.4.
1252 Added new ICU test case which illustrates removal of diacritics.
1254 --- 3.0.41 2008/12/29
1256 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1258 --- 3.0.40 2008/12/29
1260 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1263 Fixed bug #2352: yaz-marcdump crashes for certain record.
1265 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1267 Added support for Danmarc2 to UTF-8 conversion.
1269 Added support for ISO5426 to UTF-8 conversion.
1271 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1272 implementation version.
1274 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1276 --- 3.0.38 2008/11/10
1278 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1279 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1281 ZOOM C now interprets databaseName option for ZOOM connection as path
1284 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1286 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1288 Dummy Libxml2 types no longer defined in headers of YAZ'.
1290 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1293 --- 3.0.36 2008/09/26
1295 Various ODR chapter fixes.
1297 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1299 Added missing source for Windows compilation, mutex.c.
1301 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1303 For SRU connections in ZOOM all records up to "count" are now fetched.
1305 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1306 in Windows due to bad error handling for Libxml2.
1308 Added facility for sending arbitrary records (ASN.1 any) using
1309 ZOOM C's Extended service update. Patch by Sam Reynolds.
1311 New options for ZOOM C's connection, logapdu which makes ZOOM log
1314 --- 3.0.34 2008/06/18
1316 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1318 --- 3.0.32 2008/06/12
1320 Fixed memory violation that could occur when decoding UTF-8. This bug
1321 was only present in 3.0.30 of YAZ.
1323 --- 3.0.30 2008/06/06
1325 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1326 GNU TLS is used by default (if found).
1328 yaz-ztest returns OPAC records if a client asks for OPAC.
1330 Improved speed of MARC-8 encoding.
1332 Added support for lossy and loss-less MARC-8 encoding.
1334 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1336 Added new Windows Service wrapper (sc).
1338 yaz-client's itemorder command may now send a file.
1340 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1342 Added new function yaz_log_xml_errors.
1344 Allow (but warn) unknown XML attributes in MARCXML parsing.
1346 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1348 The UTF-8 to MARC-8 conversion now uses a different set of characters
1349 for Greek symbols. Bug #2120.
1351 --- 3.0.26 2008/02/21
1353 Added yaz_daemon (daemon.h).
1355 Fixed bug #2068: pkg-config trouble
1357 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1359 --- 3.0.24 2008/01/28
1361 Document --with-xml2 option.
1363 Added OPAC XML XSD (etc/opacxml.xsd).
1365 Allow glob mask for name attribute in retrieval element for the
1366 generic frontend server's retrieval facility.
1368 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1369 except POLLIN/POLLOUT.
1371 Fixed error handling in cs_listen. Bug #2037.
1373 --- 3.0.22 2008/01/20
1375 Fixed version in yaz/yaz-version.h.
1377 Fixed bug #2027: Crash when closing connection.
1379 Changed configure so that ICU support is only enabled if only ICU
1380 and Libxml2 is available (because the ICU chain is XML based).
1382 --- 3.0.20 2008/01/15
1384 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1385 is built. Only this DLL depends on the ICU runtime.
1387 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1388 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1390 Changed license of CCL module to 'Revised BSD'. After consultation with
1391 remaining members of the original EUROPAGATE consortium, we are re-issuing
1392 the CCL module without a separate license. The software was developed by
1393 Index Data as part of a research project. The special license was included
1394 to help feed usage information back to the project consortium to support
1395 project evaluation. At this time, the project consortium has long-since
1396 disbanded, and the majority of the original principals have retired. At the
1397 same time, we have significantly modified the software during the following
1398 years, to the point where very practically no original code remains. To
1399 simplify re-use of the software, we have contacted those members of the
1400 consortium who could be reached, and agreed to re-issue the module as a
1401 proper part of the YAZ package.
1403 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1405 CQL closer to being version 1.2 compliant. CQL also allows free-form
1406 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1409 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1410 bug could make Extended services handling crash in the ZOOM layer. This
1411 bug was only present in YAZ 3.0.18.
1413 --- 3.0.18 2007/12/19
1415 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1418 yaz-marcdump reads and writes collection wrapped records.
1420 Handle OPAC for record conversion module.
1422 Fixes for ICU wrapper.
1424 Allow ICU libs to be controlled with --with-icu .
1426 --- 3.0.16 2007/11/12
1428 Added yaz_poll which is a wrapper for select/poll. When poll is available
1429 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1430 sockets to be in use.
1432 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1433 functionality through an XML based configuration (ICU chain). This system
1434 is useful for search facilities such as Pazpar2 and Zebra that needs to
1435 perform tokenization of indexed material. The ICU code in a separate
1436 library libyaz3_icu.a.
1438 Added HTTP tunnel facility for COMSTACK, bug #1752.
1439 This is a facility that allows a Web proxy, such as squid, to tunnel
1440 Z39.50 traffic. This facility is "transparent" to must applications
1441 using YAZ. It's enabled by using pseudo transport connect: followed by
1442 the proxy address, followed by command, then follwed by he regular
1443 "virtual" addresss. For example,
1444 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1446 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1448 --- 3.0.14 2007/09/21
1450 Fixed bad memory reference in ZOOM_record - cuased by member not being
1451 initialized. This was a problem only in YAZ 3.0.12.
1453 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1454 fields were not removed.
1456 Changed the way C code is generated from codetables.xml. Made a MARC-8
1457 conversion trie for each characterSet section rather than codeTable.
1458 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1459 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1461 --- 3.0.12 2007/09/12
1463 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1464 from ZOOM_record_error).
1466 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1468 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1470 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1472 Better SRW-to-Bib-1 diagnostic mapping.
1474 ZOOM C and yaz-client announces SRU version 1.2 by default.
1476 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1479 Fixed in yaz_sru_decode to allow other version than 1.1.
1481 --- 3.0.10 2007/08/22
1483 Added support for SRU scan for ZOOM.
1485 Added support for the use of the older versions or Extended Service
1486 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1487 set to the version , 1=first, 2=second, 3=third. The third version is
1488 what ZOOM C has used so far. And that, obviously, is the default.
1490 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1491 therefore in Zebra and in SimpleServer-based applications). The new
1492 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1493 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1494 which is passed into the back-end search callback function.
1496 Added support for HTTP Basic authentication in clients: the SRU/W
1497 codec encodes the username/password elements of the PDU structure
1498 appropriately, and these may be set using the "user" and "password"
1499 options in ZOOM-C applications (the same options that are used for
1500 Z39.50 authentication).
1502 --- 3.0.8 2007/06/25
1504 Fixed bug #1208: SSL appears to be broken in ZOOM.
1506 Fixed bug #1206: Libxml2 include path weirdness.
1508 Added oid_name_to_dotstring.
1510 Allow elementSetName to be specified for ZOOM C record update.
1512 Allow waitAction to be specified for ZOOM C based for Extended Services.
1514 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1515 syntax OID. Bug introduced in YAZ 3 series.
1517 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1519 --- 3.0.6 2007/06/06
1521 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1522 directory. yaz-client now reads commands from file given by option -f
1523 if specified; then tries to read .yazclientrc in current directory.
1524 Failing that, it reads .yazclientrc from user's home directory.
1526 Added support for correlationInfo Note and ID for Record Update via
1529 Added yaz-client command querycharset which specifies character set for
1530 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1531 (termListAndStartPoint).
1533 Charset ISO5428:1984 is an alias for ISO5428-1984.
1535 Implemented a way to perform scan in a result set using Z39.50. This
1536 is achieved by attaching the result set name in the characterInfo
1537 (type InternationalString) of OtherInformation in the Scan Request PDU.
1538 The result set is identified in the otherinformation by the new OID:
1539 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1540 This allows for scan in result set and faceted search . Zebra did some
1541 of this in the APT term using attribute type 8 and value being result
1542 set. Using the OtherInformation approach for this is cleaner and easier
1543 to work with in proxies and the like. This facility can be used in
1544 yaz-client using new command setscan which takes a result set as first
1545 argument, start position (APT) as second.
1547 Changed decoding of SRU XML packed records to deal with servers that
1548 have recordData with XML data with multiple root nodes. Also make
1549 comparison for recordPacking case insensitive. Again, one server
1550 returns "XML" where others return "xml".
1552 For SRU responses allow Content-Type application/xml as well as text/xml.
1554 --- 3.0.4 2007/05/21
1556 Fixed bug in character set conversion of BER strings. Bug introduced
1559 --- 3.0.2 2007/05/08
1561 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1563 For OID class, use oid_class consistently.
1565 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1568 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1569 character set for bibliographic information interchange". By Giannis Kosmas.
1571 Added documentation on new OID API.
1573 --- 3.0.0 2007/05/02
1575 Changes to generic frontend server interface: added new member
1576 'query_charset' for bend_initrequest structure. A backend init handler
1577 should set this member to its native character set for query terms.
1578 When defined, the frontend server logic will announce this character set
1579 to a client if the negotiationModel bit is set by the client. All server
1580 implementors are encouraged to specify this. If a backend server does not
1581 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1583 Added CCL utility to remove terms (stop words) from resulting RPN
1584 tree. This is handled by functions with prefix ccl_stop_words_ .
1586 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1587 terms in RPN queries.
1589 Clean-up the CCL API. Moved some internal structures from ccl.h to
1590 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1591 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1592 This is replaced by ccl_parser_find_str which takes a string instead.
1594 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1595 libyaz.la is the core of YAZ except the generic frontend server and
1596 does not depend on POSIX threads anymore. libyaz_server.la is the
1597 generic frontend server facilities and uses POSIX thread functionality
1598 if available. The libyaz.la no longer depends on POSIX threads because
1599 the number of global structures is limited. NMEM no longer re-uses blocks
1600 between threads ; it simply free's memory immediately but allocates in
1601 "large" chunks as usual. We don't expect any performance penalties
1602 because of this. The yaz_log system is still using a global log_level so
1603 caution must be taken when modifying it with yaz_log_init_.. +
1604 yaz_log_mask_str. This, however, should not cause any trouble because
1605 these functions are called during initialization of application code
1606 anyway. `yaz-config --libs server` returns libs for server applications;
1607 `yaz-config --libs` returns libs for non-server applications.
1609 New OID database - with public definitions in oid_db.h. Removed old OID
1610 database including the head oid.h and definitions such as enum oid_value
1611 and struct oident. The new OID database uses the same string names as
1612 before but the 'protocol' is gone. There are now only two representations
1613 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1614 converts from string to OID; functions with prefix yaz_oid_to_string
1615 converts the other way.
1617 Change to emit_term() in CQL-to-PQF query translation: when a term has
1618 the /regexp relation modifier, do not process it for leading and
1619 trailing "^" and "*", which have quite different meanings in regular
1622 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1623 write handlers no longer carries a 'last' parameter. This will make
1624 yaz_iconv flush "less" characters. A flush is performed by call to
1625 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1627 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1628 removed, because function yaz_query_to_wrbuf does the same.
1630 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1631 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1633 Deprecated MARC utility functions removed.
1635 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1638 Branch split: YAZ_2_1_55_branch
1640 --- 2.1.54 2007/03/16
1642 Fix to ZOOM-C so that transparent reconnection is properly handled on
1643 connections that are in asynchronous mode.
1645 Fixed compilation on OpenBSD 4.0.
1647 Large strings in GRS-1 records are now properly displayed in yaz-client.
1649 Added character conversion support for "advancegreek"; based on patch from
1652 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1653 sequence is met. Before the error was not set so it would be unknown.
1655 Adjust yaz-marcdump MARC reader so that it skips until record separator
1658 --- 2.1.52 2007/03/07
1660 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1661 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1662 fd_set structure used as a bitmask for the FDs to be selected on.
1664 Using ACX_PTHREAD macro to check for POSIX threads.
1666 Fixed have-vsnprintf check.
1668 --- 2.1.50 2007/02/23
1670 Fixes for configure on BSD. Bug #900.
1672 Added snprintf/vsnprintf wrappers for systems that don't have
1673 limits (heavens forbid).
1675 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1676 created before all previous tasks were completed and removed from the
1677 task queue, the new task could be removed by a mistake.
1679 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1681 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1683 Fixed bug #832: Problem with MARC/charset in yaz-client.
1685 Fixed bug #668: save command line history for yaz-client.
1687 Fixed bug #830: pkg-config support.
1689 --- 2.1.48 2007/01/23
1691 Extended ZOOM result set options with two options that may be read by
1692 a client: resultSetStatus and presentStatus with values as specified for
1694 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1696 Fixed bug #827: Using SSL fails on Debian etch.
1698 Fixed bug #826: Weird looking chars for set of MARC records.
1700 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1701 that is treated as an ItemOrder with itemRequest being an XML document
1702 external. The value of "doc" is the content.
1704 Extended the GFS search facility. New member of bend_search_rr
1705 'estimated_hit_count' signals that hits is known to be an estmate
1706 (higher or lower than real hit count). New member 'partial_resultset'
1707 signals that the search was partial (hit count is lower or equal than
1708 real hit count). For Z39.50, the information is stored in resultSetStatus
1709 member of SearchResponse APDU. For SRU, the information is signalled
1710 via SRU diagnostic 59: "Result set created with valid partial results
1713 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1715 --- 2.1.46 2007/01/13
1717 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1719 Added ZOOM_connection_peek_event.
1721 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1722 the following new functions:
1723 ZOOM_event_nonblock, ZOOM_connection_process,
1724 ZOOM_connection_get_{socket,mask,timeout},
1725 ZOOM_connection_fire_event_{timeout,socket}.
1726 The existing blocking event handler, ZOOM_event, is a wrapper for the
1727 + blocking ZOOM_event_sys_{poll,select}.
1729 Implemented function ccl_xml_config which parses XML version of CCL
1730 configuration (bug #798).
1732 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1734 Added timings utility (yaz/timing.h)
1736 --- 2.1.44 2007/01/03
1738 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1741 Fixed bug #779: Rotation of apdu.log fails.
1743 Fixed for character set conversions:
1744 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1745 Honor G1 set in MARC-8 decoding.
1747 --- 2.1.42 2006/12/17
1749 Fixed bug #775: char conversion does not handle Alternative UTF-8
1752 Implemented function yaz_marc_read_line which parses MARC line format
1753 records. There is a wealth of formats out there. So far, this function
1754 reads line records produced by yaz_marc_write_line.
1756 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1757 more generic and easier to remember(!) options: -i format and -o format
1758 which specifies input format and output format respectively - where
1759 format is one of "marc", "marcxml", "line", "marcxchange".
1761 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1762 does not print anything except warnings for records.
1764 For yaz-marcdump, added support for MARC split into files (-s) with a given
1767 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1768 spec, at http://www.loc.gov/standards/sru/record-update/
1769 This has changed the binary layout of the following structs:
1770 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1771 bend_update_rr . Patch by Ko van der Sloot.
1773 Added GFS utility function bend_assoc_is_alive which returns 1 if
1774 association is still alive (client is connected); 0 otherwise (client
1775 closed connection). This allows busy servers to stop working for
1778 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1779 been a separate piece of software. This version of ziffy has been modified
1780 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1782 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1784 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1785 Client code may now interrogate options such as "init_opt_sort" to
1786 find out whether the server claims to support various options.
1788 --- 2.1.40 2006/11/27
1790 Added utilities yaz_{set,get}_esn to set/get element set name from
1793 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1794 of YAZ and has been so since YAZ 2.1.10.
1796 Implemented ZOOM_record_error which returns error information for
1797 record (surrogate diagnostic).
1799 --- 2.1.38 2006/10/31
1801 Updates for SRU Update by Ko van der Sloot:
1802 1. Changed name from "operation" to "action"
1803 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1804 versions in the code, marked as 'backward compatible'.
1805 3. Added diagnostics for SRU Update.
1807 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1809 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1811 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1813 For GFS, fixed problem with SRU diagnostic 'First record position out of
1814 range' being issued for 0 hits.
1816 zoomtst10 part of Windows Build.
1818 --- 2.1.36 2006/10/13
1820 Implemented yaz_filepath_comp which splits a path into file path
1821 components (required by Zebra 2.0.3+).
1823 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1824 BSD inspired license until now so this should not have any real impact on
1825 anybody. See http://www.opensource.org/licenses/bsd-license.php
1827 Fixed bug #687: Missing log lines.
1829 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1832 Fixed bug #689: SRU diagnostics to be added.
1834 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1835 whether a connection is idle (no more work do do).
1837 --- 2.1.34 2006/10/04
1839 Change type of optval from long to int for invocation of setsockopt with
1840 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1842 Added support for specifying the max log file size for the Generic
1843 Frontend Server. The size is given with option -r.
1845 --- 2.1.32 2006/09/21
1847 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1849 --- 2.1.30 2006/09/17
1851 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1854 Fixed bug in Generic Frontend Server that could cause a server to stop
1855 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1857 For the generic frontend server, the maximum record size is used as maximum
1858 size of incoming packages (SRU + Z39.50). The value until was previously
1859 only used in Z39.50 Init negotiation and, later, in a session controlled
1860 sizes of records returned. This is controlled using -k option. It can be
1861 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1863 --- 2.1.28 2006/09/04
1865 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1868 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1870 New option for yaz-marcdump -lpos=value which allows setting a portion
1871 of MARC header to a certain value.
1873 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1875 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1876 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1878 --- 2.1.26 2006/08/15
1880 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1883 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1885 --- 2.1.24 2006/08/08
1887 Fixed MARC ISO2709 encoding routines to deal with character set
1890 Minor changes to GFS logging. Database included in search request log
1893 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1894 cached/multiple records.
1896 Shared libraries are built by default on Unix+configure.
1898 Changed cql2pqf transformation to use a different evaluation order. The
1899 new order is: always, relation, structure, position, truncation, index
1900 and relationModifier. Old order was: always, relation, relationModifier,
1901 structure, index, position, truncation. Note that the the latter ones
1902 override former ones for identical attributes.. The new scheme means that
1903 it is possible to override any existing attribute with a relationModifier.
1904 And also that it is possible to override everything for the index rule
1905 (except the ones listed in relationModifier). No order is perfect but this
1906 one, we believe, covers more real cases.. The "always" should have been
1907 called "default", since the attributes there can be overridden with all
1910 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1911 compilation phase, but also for yaz-config --cflags output. This allows
1912 us to have public headers with Libxml2 stuff in them . It should also,
1913 eventually, make Libxml2 checks redundant in packages using YAZ, such
1916 --- 2.1.22 2006/06/15
1918 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1919 stored in uri, message and details.. Previously diagnostics were stored
1920 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1921 compatibility.. but he's probably the only one affected, so.
1923 Added support for CCL, compiled on the client side, in ZOOM-C. This
1924 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1925 input; the resulting query objects can be used for for searching with
1926 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1928 YAZ' configure searches for OpenSSL by default.
1930 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1931 SL_CTX_use_certificate_file. See
1932 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1933 for more info. Thanks to Ko van der Sloot.
1935 --- 2.1.20 2006/06/02
1937 Bug #600: SRU GET, POST support for yaz-client. Introduced
1938 command 'sru' which selects method SOAP/GET/POST.
1940 Allow missingValueAction to be specified for the sortspec string -
1941 function yaz_sort_spec. By default, the missing value action is null.
1942 Use ! to specify "abort". Use = followed by stringvalue to specify default
1945 Ensured that Present-handler (if defined) is called in GFS before any call to
1946 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1947 searchRetrieve requests.
1949 Documentation for YAZ is now based on the Docbook XML/XSLT using
1950 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1951 is no longer depending on jade/openjade or docbook-to-man scripts.
1952 PDF is no longer part of the distribution - but can optionally be
1953 made using DSSSL/jadetex or FOP.
1955 Added retrieval handling support in Generic Frontend Server to support
1956 conversion between MARC/XML as well as XSLTtransforms. See
1957 etc/yazgfs.xml for an example.
1959 Added Authentication support to Generic Frontend Server in SRU
1960 mode. Authentication using HTTP Basic is supported, as is the use
1961 of 'x-username' and 'x-password' parameters in the request itself.
1963 Added support for a new character set MARC8s identical to MARC8 except
1964 that it converts combined characters to single Unicode characters in the
1965 Latin-1 range (when possible).
1967 --- 2.1.18 2006/04/24
1969 ASN.1 compiler 0.4: generates brief Doxygen file header for
1970 generated .h/.c files.
1972 Utility yaz_iconv now supports conversion to MARC-8.
1974 New facilities for the MARC module. The reading - and writing of
1975 content are separate methods for the yaz_marc_t handle. The following
1976 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1977 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1978 format). Write functions have prefix yaz_marc_write_.. The existing
1979 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1980 available. Removed support for OAI-MARC and simplexml (not the
1981 simplexml from PHP5).
1983 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1984 to be returned for this connection.
1986 --- 2.1.16 2006/03/31
1988 Allow multiple languages and charsets to be specified with
1989 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1990 negcharset iso-8859-1,utf-8
1992 Translation of proximity nodes from CQL into PQF now works.
1994 Moved to automake 1.8, 1.9.
1996 Added function yaz_log_set_handler which allows a log handler to be
1997 installed. This handler will be called for all log messages. Output
1998 to file is also produced; but that can be disabled by passing NULL
1999 fname to yaz_log_init_file.
2001 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2003 For SRW (including GFS), accept application/soap+xml as content-type
2006 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2007 produces NO stylesheet reference even if a default stylesheet is specified
2010 --- 2.1.14 2006/03/14
2012 Updated Windows package to include yazd.dll + yazd.lib for the
2013 Development component.
2015 If the environment variable YAZ_LOG is set, then it is used as a
2016 string indicating the default level of logging to use if not
2017 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2018 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2019 used as before. So, for example, to omit warnings from YAZ logging,
2020 export YAZ_LOG=-warn
2022 cql_transform() now map structure and other attributes before indexes,
2023 so that index-specific structures and other attributes can override
2024 defaults. So now a combination of mapping specifications such as:
2026 index.dc.date = 1=date-modified 4=5
2027 does the right thing.
2029 cql_transform() now also respects the "always" mapping specification,
2030 which establishes an initial set of attributes to be used for all
2031 terms except where overridden by more specific attributes associated
2032 with the index, relation or modifier.
2034 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2035 which mode to use; one of "post", "get" or "soap" (SRW, default).
2037 Fixes for yaz_iconv routines: changed trie-based character set conversions
2038 to use only non-negative values for bit fields due to Sun's C compiler not
2039 supporting negative values.
2041 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2042 sequences where not read correctly. Fix by Rustam Usmanov.
2044 Updated win/makefile to use options, settings which makes things
2045 compile with VS C 2005.
2047 --- 2.1.12 2006/02/01
2049 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2051 In ZOOM socket code, use select instead of poll on MacOSX.
2053 ZOOM-C now support client-side compilation of CQL into RPN that is
2054 sent to the server, enabling CQL to be used against all Z39.50
2055 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2056 ZOOM_query object, and submit it using ZOOM_connection_search().
2057 The CQL-to-RPN translation uses a configuration file, the name of
2058 which must be specified in the Connection's "cqlfile" option.
2060 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2061 function, which takes as its start-term parameter a ZOOM_query object
2062 (which may have had either CQL or RPN set into it).
2065 --- 2.1.10 2005/11/29
2067 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2068 GFS to support this as well. Backend handler, bend_srw_update, does the
2069 update work. Code contributed by Ko van der Sloot.
2071 Allow retrieval of Search Result-1 information in ZOOM by the use of
2072 options that are attached to a result set. ZOOM documentation updated
2075 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2076 UTF-8 conversion. Patch by Raj Patel.
2078 Added option -m to GFS to control formatting of timestamps in log file.
2080 Added 'exit' as synonym for 'quit' in yaz-client
2082 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2083 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2084 for the new members. Patch by Ko van der Sloot.
2086 Added support for SRU POST. It is supported for content-type
2087 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2089 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2090 Instead make the library libyaz.la multi-threaded. Threading as a whole
2091 can still be disabled by configure option --disable-threads. Previosly,
2092 with older GLIBCs there were problems with MT libs under Apache. This
2093 has now been fixed a long time ago.
2095 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2098 CQL module modified to be case insensitive for relations/indexes/operations.
2100 Fixed bug in CQL transform code: incorrect value relationModifieder
2103 Added 'show all' command for yaz-client which retrieves all results
2106 Added new yaz-client, xmles, which takes a (private) OID and
2107 a document to be sent as an extended service request.
2109 Describe new yaz-client commands wait_response and set_auto_wait.
2111 Increase TCP/IP listener backlog from 3 (which I am guessing was
2112 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2113 that the socket will queue as many incoming connections as it's able
2114 to handle ongoing connections. In other words, it will never now
2115 refuse a connection that it would be able to handle merely because
2116 it's not got around to accepting() enough of the pending connections
2117 yet. This is the behaviour anyway under Linux, where the listen()
2118 argument is ignored; but not under BSD and on systems such as
2119 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2120 YAZ-based servers should now be uniform across operating systems in
2123 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2124 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2125 This allows yaz-marcdump to read large MARC batches (>2 GB).
2127 Modified all YAZ source files - except the source which is auto-generated
2128 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2131 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2132 corresponding to the existing *_setl() function. These allow option
2133 values containing arbitrary valuues.
2135 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2136 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2137 except that it returns an indicator of whether or not the sort
2138 criterion was accepted (0 for OK, -1 for invalid).
2140 --- 2.1.8 2005/06/07
2142 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2143 MARC output rather than returning "new" buffer.
2145 yaz-client warns about unknown init options.
2147 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2149 --- 2.1.6 2005/05/24
2151 Added support for SRW sort in Generic Frontend Server. Patch
2152 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2153 sortKeys - or NULL if none is provided.
2155 Fixed bug #307: It was impossible to specify indefinite/no timeout
2156 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2159 Added support for multiple languages and charsets to be specified in
2160 ZOOM. Each charset/language is separated by a blank. If negotiation is
2161 in effect in init-response, Option
2162 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2163 Code based on patch by Vasiliy Osadchuk.
2165 Fixed bug #306: infinite recursion that occurred when calling
2166 yaz_log_level_init as the first call (before other log level or
2169 Fixed bug in scan handling in front end server: if preferred-Position-In-
2170 Response was non-present, a NULL pointer referece was performed.
2172 --- 2.1.4 2005/04/26
2174 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2175 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2176 now defined for all those error codes. So instead of putting 109 in
2177 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2178 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2180 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2183 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2185 Program yaz-client now exits and produces an error message if multiple
2186 Z39.50 servers are specified on the command line (none or one allowed
2189 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2192 --- 2.1.2 2005/03/16
2194 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2196 Fixed bug #272: Preserve spacing for CCL terms.
2198 --- 2.1.0 2005/03/14
2200 Added support for virtual hosts and multiple backend servers for
2201 the YAZ frontend server. The configution is XML based and
2202 support specificition of CQL to RPN mappings and explain information.
2203 See section "Virtual Hosts" in the YAZ manual.
2205 Extended OPAC display utility. OPAC display utility renders
2206 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2207 to supplement yaz_marc_decode_wrbuf.
2209 Fixed a bug in MARC decoder that could caused it to crash for some
2210 invalid MARC records. More diagnostics and warnings where added in
2211 XML output (warnings, etc are stored in comments).
2213 --- 2.0.34 2005/02/08
2215 Fixes for UNIX domain sockets. Bug #261.
2217 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2219 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2220 Added yaz_marc_subfield_str which defines subfield lead string which is
2221 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2222 yaz_marc_endline_str which defines end of fields string used in
2223 YAZ_MARC_LINE format. Default string is newline.
2225 Experimental support for MarcXChange. This format can be produced
2226 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2227 http://www.bs.dk/standards/MarcXchange.xsd
2229 Added yaz-client commands scansize that sets maximum number of
2230 entries to be returned by scan.
2232 --- 2.0.32 2005/01/11
2234 Added support for SRW scan in yaz-client and Generic Frontend Server.
2236 * Added whereInList member to SRW Scan Term.
2238 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2240 Fixed NMEM system to return aligned blocks on the smallest boundaries
2241 that are suitably aligned for all possible types on the particular
2242 architecture YAZ is being built for.
2244 --- 2.0.30 2005/01/04
2246 Fixed numerious warnings that was issued with newer versions of GCC.
2248 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2249 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2252 Make YAZ Generic Frontend Server slightly faster.
2254 Enhance (and reduce) logging for Generic Frontend Server.
2256 Revert YAZ log system so that it flushes every write operation
2257 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2259 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2260 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2261 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2262 will effectively disable old definitions.
2264 --- 2.0.28 2004/11/09
2266 Added yaz_log_time_format which specifies log format using
2269 Added yaz_log_module_level which returns mask for a module. Value
2270 is non-zero mask a if module is enabled; zero if disabled.
2272 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2273 in include/yaz/cql.h.
2275 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2277 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2279 Fixed bug #172: RPM builds does not enable SSL.
2281 Doxyfile.in part of dist. Doxyfile generated by configure.
2283 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2284 are given and the corresponding component does not exist.
2286 Extend CCL documentation in YAZ reference. Describe r=r.
2288 --- 2.0.26 2004/10/01
2290 Fixed MARC->MARCXML conversion to properly deal with
2291 fields, subfields, indicators having non-ASCII characters.
2293 Fixed MARC->MARCXML conversion so that ASCII control characters
2294 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2297 Added YAZ GFS support for conversion from Z39.50 surrogate
2298 diagnostics to SRW surrogate diagnostics.
2300 Bug fix: YAZ GFS did not return schema in explainResponse.
2302 --- 2.0.25 2004/09/30
2304 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2305 now converts recordSchema to elementSetName as well as schema URI.
2307 Fixed bug in COMSTACK that prevented HTTP request packages from being
2310 --- 2.0.24 2004/09/29
2312 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2313 does not require white-space before and after the dash in a range, e.g.
2314 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2317 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2318 due to new GCC removing "redundant" code.
2320 Added yaz-client commands scanpos and scanstep that sets preferred
2321 position and step-size for scan.
2323 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2325 Added CCL utility ccl_qual_buf which parses one or more CCL
2326 spec lines in a buffer.
2328 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2329 of name and value - ignoring empty lines and comments.
2331 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2333 Added odr_get_element_path which returns current element path for an
2334 ODR handle. This utility is useful in error handling or user-defined
2337 Added ODR_PRINT utility odr_set_stream which is is a more generic
2338 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2339 to a write function and pointer to close function. The close function - if
2340 non-NULL - will be called during odr_destroy.
2342 Fixed bug in CCL parser where truncation char was not removed from
2343 right side when truncation=both was in effect.
2345 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2348 --- 2.0.23 2004/08/11
2350 Fix buffer overrun in CQL parser when dealing with proximity (%).
2352 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2353 to UTF-8/UCS conversion is now only based on codetables.xml.
2355 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2357 --- 2.0.22 2004/08/06
2359 Add support for more "commit changes" in ZOOM (uses Extended Services).
2361 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2364 Yet another small fix for configure of SSL.
2366 --- 2.0.21 2004/05/14
2368 Fix SSL libs for configure when --with-openssl=DIR is given.
2370 --- 2.0.20 2004/05/10
2372 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2374 SSL comstack now uses yaz.pem certificate file on server side
2375 by default. Certificate filename can be configured by calling
2376 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2378 Fix bug regarding multiple calls to ZOOM_connection_connect.
2380 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2382 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2383 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2385 ZOOM now allows inspection of X509 peer certificate for verification.
2386 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2388 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2389 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2390 as "modular" but it simplifies things.
2392 Added cs_get_peer_certificate to that returns peer X509 PEM.
2394 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2395 NULL if SSL is unavailable.
2397 Documentation about MARC decoding tools.
2399 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2401 --- 2.0.19 2004/03/30
2403 Rename CHANGELOG to NEWS to follow GNU style packing.
2405 Fix bug with missing initialization of member in init_diagnostics.
2406 This bug affects threaded version of GFS server.
2408 --- 2.0.18 2004/03/20
2410 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2413 Ensure zlib.dll is packed with Windows install.
2415 --- 2.0.17 2004/03/17
2417 Fix encoding of xsd:string to use text instead of CDATA.
2419 Fix endless loop in CQL parser with unbalanced ".
2421 Use a more compact way to store MARC-8 conversion tables.
2423 --- 2.0.16 2004/03/16 Debian only
2425 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2428 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2433 --- 2.0.15 2004/03/01
2435 Another fix for decoding of XML packed records.
2437 --- 2.0.14 2004/02/25
2439 Fixes for Chunked encoding. White space not ignored after length spec.
2441 Update NS and use default NS for SRW diagnostic elements.
2443 --- 2.0.13 2004/02/23
2445 Implement ZOOM_resultset_cache_reset which resets record cache.
2447 Implement ZOOM_resultset_sort which sorts a result set.
2449 Implement chunked HTTP transfer.
2451 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2453 --- 2.0.12 2004/02/16
2455 Added member 'schema' to bend_explain_rr structure so that backend
2456 can specify explain record identifier. Defaults to Zeerex 2.0.
2458 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2460 --- 2.0.11 2004/02/16
2462 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2465 Added init command for yaz-client which sends "extra" init request.
2467 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2468 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2470 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2472 Make ZOOM error code for "invalid query".
2474 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2476 --- 2.0.10 2004/02/05
2478 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2481 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2483 Added option -p <file> to make Generic Frontend Server to write PID file.
2485 Added option -D to put Generic Frontend Server in background on its own.
2487 Make ZOOM C recognize option "password". If unset, "pass" is used
2488 (for backwards compatibility).
2490 Fixed a bug in Generic Frontend Server that could make it crash if a
2491 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2494 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2495 Must be issued before open, in order to be in effect.
2497 --- 2.0.9-6 2004/01/12 Debian/Windows
2499 Make the SRU server more picky WRT unknown params, etc.
2501 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2503 New YAZ client command, options, that sets Z39.50 options.
2505 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2506 options from a string of tokens (one token for each option bit).
2508 Update SRW diagnostic code messages.
2510 --- 2.0.9-5 2004/01/07 Debian/Windows
2512 Handle user defined stylesheet for SRW/SRU.
2514 --- 2.0.9-4 2004/01/06 Debian/Windows
2516 Fix bug in decoding of Content-Length.
2518 --- 2.0.9-3 2004/01/06 Debian/Windows
2520 Fix a bug with decoding of XML packed records.
2522 --- 2.0.9-2 2004/01/05 Debian only
2524 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2526 Fix bug in SRW/SRU diagnostics decoding.
2528 --- 2.0.9 2004/01/05
2530 Fixed bug in Generic Frontend Server which could drop records exceeding
2531 preferred message size. Reported and fixed by Irina Dijour.
2533 Fixed calculation of package size for structured records in Generic
2534 Frontend Server. Reported and fixed by Irina Dijour.
2536 Fixed namespace for SRW/SRU diagnostics.
2538 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2540 --- 2.0.8 2003/12/22
2542 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2543 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2546 CQL changes to reflect recent changes to the specification:
2547 * Documentation talks about context sets instead of index sets.
2548 * Documentation talks about indexes instead of qualifiers.
2549 * The CQL-to-PQF transformer's configuration file now uses
2550 "index.set.name = <attributes>" instead of the old form
2551 "qualifier.set.name = <attributes>". (Both forms are still
2552 understood but the latter is deprecated.)
2553 * CQL terms with no explicit index specified are now interpreted as
2554 cql.serverChoice instead of srw.serverChoice (which of course
2555 behaves exactly the same.)
2557 --- 2.0.7 2003/12/16
2559 MARC conversion can now generate ISO2709 output in another
2560 character set. yaz-marcdump uses this facility if you invoke it
2563 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2564 functions from there can be used from C++.
2566 --- 2.0.6 2003/12/04
2568 Frontend server now transfers memory from decoded packages to stream
2571 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2572 references to show up.
2574 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2575 the ZOOM Abstract API. The older names for the same options are still
2576 also supported for the benefit of old applications.
2578 ZOOM-C supports "implementationId" and "implementationVersion" options
2579 to go along with "implementationName". These allow the user code to
2580 specify identification strings to be sent to servers.
2581 Add OID for the new ExtLite attribute set.
2583 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2584 as requested/supplid by Ere Maijala <ere@atp.fi>
2586 For generic frontend server, reverse the order of
2587 "toolkit-supplied / application-supplied" strings sent as implementationId,
2588 Name and Version. Also, remove the spaces around the slash. This brings
2589 the GFS in line with the behaviour of ZOOM-C on the client side.
2591 Add function ZOOM_scanset_display_term.
2593 yaz-client shows scan displayTerm if present.
2595 Utility yaz-iconv is now installed by default along with the man page
2598 Extend configure check for OpenSSL to use pkg-config where available (such
2601 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2602 server to specify uid/gid/mask for socket using the format
2603 unix:[user=uid,][group=gid,][umask=mask,]file=path
2604 If file= is omitted the existing format is assumed, e.g.
2606 in which case the mask is 0666 (rw for everybody).
2608 Major restructure of YAZ source. All source in libyaz is in src directory.
2609 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2610 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2612 Added man page for utility yaz-marcdump (used to be called marcdump).
2613 yaz-marcdump is installed by 'make install'.
2615 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2616 of incoming package failed.
2618 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2620 Change prototype of odr_perror: add const to message string.
2622 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2624 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2625 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2626 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2627 DNS lookup. There should not be any compatibility problems with this
2628 assuming that blocking=1 or 0 is used.
2630 Fix bad reference in UNIX comstack in function cs_addrstr.
2632 Fix for compilation on AIX.
2634 The generic front-end server (server/seshigh.c) now supports returning
2635 Init diagnostics to the client in User-information-field, in
2636 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2639 --- 2.0.4 2003/09/04
2641 Allow any CQL relation (not just all,any,exact,scr).
2643 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2644 that features the same UI.
2646 Implemented command update0 in YAZ client which is equivalent to
2647 update but uses old of Ext Update ASN.1.
2649 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2650 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2651 Previously no OID was used for this info.
2653 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2654 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2655 returns 'malformed search term' otherwise.
2657 SortResponse member resultCount now set to NULL in sort handler of
2660 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2663 Add three new utility functions for translating OIDs between various
2664 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2665 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2666 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2667 char *oid_to_dotstring(const int *oid, char *oidbuf);
2668 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2670 Reverted modifications for ES Update definition for z_IU0Update
2671 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2672 is back to YAZ 2.0.2.
2674 String value attributes for CCL parser.
2676 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2677 which their FirstSearch server returns in Init responses, sometimes
2678 carrying useful diagnostic information when Init fails. This has the
2679 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2680 "z39.50/oclcui.asn", where its definition is somewhat different from
2681 what OCLC document on their web-site, as required to interoperate with
2684 Support for anonymous authentication in yaz-client. Use the command
2687 * Fix the OID of the Index Data-local "admin" Extended Service from
2688 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2689 the 1000, which indicates a locally-defined OID, was a mistake.
2691 --- 2.0.3 2003/06/20
2693 Fix CCL directive @case handling so that it affects string match for
2694 both CCL keywords and qualifiers.
2696 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2697 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2698 Decoder has been updated with ASN.1 changes as listed in
2699 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2700 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2701 z_IUUpdate, remains unchanged.
2703 ZOOM_record_get may now return a record in a specific character set.
2704 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2705 "from" is the character set of record as returned by target. "to" is
2706 the character set to be returned. If omitted, "to" is UTF-8.
2708 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2710 New ODR utility, odr_getelement, which returns name of element for
2711 which encoding/decoding failed.
2713 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2714 in cases where a required element was omitted.
2716 Bug fix: some MARC8 sequences were not converted.
2718 New ZOOM option "step" which specifies number of records to be
2719 retrieved in one chunk. Used in conjunction with "start" and "count".
2721 SRW support for yaz-client. Use scheme http: to use it, e.g.
2724 yaz-client no longer does (un)intelligent character set conversions
2725 by default. Can be enabled with charset and marc_charset commands.
2727 xmalloc trace fix for 64-bit systems such as DEC alpha.
2729 Solaris 2.6 compile fix.
2731 New function, cql_strerror() translates SRW error codes, as returned
2732 by cql_transform_error(), into human-readable English strings. Used
2733 in yaz-client diagnostics when appropriate.
2735 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2736 converts it into a type-1 query which is sent to the server. This
2737 makes CQL available for use with all Z-servers, as opposed to the tiny
2738 minority that can handle CQL queries themselves.
2740 --- 2.0.2 2003/04/28
2742 New Debian package layout similar to the Redhat Package layout.
2744 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2745 and search result respectively.
2747 --- 2.0.1 2003/04/25
2749 Redhat package is now several packages: libyaz (runtime libraries),
2750 libyaz-devel (development and documentation, and yaz (utility programs).
2751 Package spec file by Morten Bogeskov.
2753 New member 'schema' in struct bend_fetch_rr which the name of requested
2754 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2755 handler MAY set this to reflect the schema of the returned record.
2757 New member 'display_term' in struct scan_entry. GFS now sets member entries
2758 and allocates scan entries to be filled by user scan handler. In previous
2759 version, entries member was allocated by the scan handler. That still works,
2760 but the GFS will ignore member display_term - assuming it was NOT set by
2761 the handler. The fact that the GFS now allocates the entries both allows
2762 for new members and makes a scan handler easier to write.
2764 Fix CQL lex buffer overflow.
2766 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2767 SRU default recordPacking is string.
2769 SRU protocol support for frontend server.
2771 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2773 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2775 Added scan for the ZOOM shell (zoomsh).
2779 * String Identifers for Schemas (Amendment 5).
2780 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2781 Old definition for schema
2782 Odr_oid *schema; /* OPT */
2787 Z_InternationalString *uri;
2788 #define Z_Schema_oid 1
2789 #define Z_Schema_uri 2
2792 * resultCount parameter to Sort Response (Amendment 1).
2793 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2795 Support for SRW 1.0 over HTTP. This is an optional feature and
2796 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2799 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2800 on the same port. SRW SearchRetrieveRequests are mapped
2801 to bend_init,bend_search,bend_fetch,bend_close.
2803 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2805 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2806 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2808 ZOOM connections are SRW based if schem http is used for hostname
2809 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2810 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2812 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2813 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2814 distance=n, order=true/false, relation=le, prox unit=word. If
2815 n is omitted, distance 1 is used.
2817 Fixed problem with C compiler include path in wrong order.
2819 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2820 on Solaris. Patch from Ko van der Sloot.
2822 New MARC decode API. All new functions operate on a yaz_marc_t
2823 handle. The most important new functions are: yaz_marc_create,
2824 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2825 decode and destroy respectively. Decoder can produce formats
2826 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2827 include/yaz/marcdisp.h.
2829 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2830 to UTF-8, UCS-32, wchar_t or Latin-1.
2832 * Prototypes for yaz_iconv_-functions moved to separate header
2833 include/yaz/yaz-iconv.h.
2835 Make a few private functions 'static' in unix.c. This prevents
2836 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2838 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2839 are set when Init Response is received.
2841 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2842 but returns diagnostic set as well.
2844 New function yaz_strerror which is a portable wrapper for
2845 strerror/strerror_r/GetLastMessage.
2847 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2848 is returned for MARC. If type is "oai", then OAI MARC is returned.
2850 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2853 --- 1.9.2 2002/11/26
2855 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2857 Fix bad race conditions on SIGTERM and terminate gracefully in
2860 Move retrieval (data1) module to Zebra since nobody seems to be
2863 Add GRS-1 render for ZOOM using same format as yaz-client.
2865 --- 1.9.1 2002/10/05
2867 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2869 Fix broken ESpec handling in data1 module.
2871 SGML reader parses comments and makes them part of the data1 tree.
2873 Added several type casts so that YAZ compiles as C++ code.
2875 ZOOM didn't handle PDU encoding failures properly.
2877 Added more Bib-1 diagnostics (approved extensions).
2879 GNU configure: better check for iconv.
2881 More portable use of accept, getpeername. Check for socklen_t. Use
2882 int/size_t if socklen_t is not defined.
2886 PQF parser rejects bad queries - including those with extra
2887 characters in them. PQF parser used to silently ignore that.
2888 Cleaner API for PQF added, which allows you to get detailed
2889 error information for bad queries (see yaz/pquery.h).
2891 Fixed bug in ZOOM_record_get for type "database".
2893 Implemented mini iconv library supporting conversions between
2894 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2896 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2898 --- 1.8.9 2002/08/20
2900 Fixed ZOOM C record cache so that preferredRecordSyntax and
2901 elementSetName is used to check for already fetched records.
2903 --- 1.8.8 2002/08/02
2905 Added three members in bend_initrequest structure to facilitate
2906 character set negotiation.
2908 Fixed a bug in frontend server that could cause indefinite
2909 loops under rare conditions.
2911 Revised character set utilities (charneg.h) so that encoding
2912 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2914 For PQF, directive @term <type> sets term type for Scan/Search.
2915 Here <type> is general, string, numeric, null. The term type
2916 is inherited - just like @attr.
2918 New call odr_set_charset that sets character set conversion for
2919 international-strings on a ODR stream. Prototype is:
2920 int odr_set_charset(ODR o, const char *to, const char *from);
2921 The InternationalString is still represented as C string in YAZ
2922 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2923 won't). On the protocol level, you can use any encoding.
2925 Support for UNIX sockets in ZOOM.
2927 Solaris recv sometimes returns errno == ENOENT. It is treated as
2928 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2930 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2931 both client and server. Code by Morten Bogeskov.
2933 --- 1.8.7 2002/05/22
2935 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2936 that they can be used directly from Visual Basic. You must recompile
2937 your windows APP if you're using ZOOM.
2939 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2940 Commands "lang" and "charset" sets language and character set respectively.
2941 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2942 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2944 Attributes from multiple CCL fields may be OR'ed rather than merged
2945 using directive "@field or". Fields are still merged by default -
2946 equivalent to "@field merge".
2948 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2951 Fixed bug in zget for parameter ExtendedServicesResponse.
2955 --- 1.8.6 2002/03/25
2957 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2959 Client displays USR.1:SearchResult-1 (hits per term).
2961 Additional Search Info for search in Generic Frontend Server.
2963 Fixed CCL parsing of "field=s".
2965 WIN32 installer - using the excellent NSIS software from nullsoft.
2967 Fixed CCL parsing of "field = - <number>".
2969 Added function yaz_marc_decode that decodes MARC for line mode
2970 display or XML (similar to that used by JZKit).
2972 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2973 Z39.50. But ISO/ILL was, however.
2975 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2976 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2978 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2979 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2981 --- 1.8.5 2002/02/03
2983 New YAZ client features: Command completion and new commands:
2984 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2985 Code provided by Jacob Poulsen.
2987 New call oid_trav, that visits all registered OIDs via callback.
2989 Function ZOOM_record_get now returns const char pointer rather than
2990 void pointer. It saves a lot of type casts.
2992 For YAZ client, command "auth" now allows you to set authentication
2993 in IdPass style. It is enabled when three tokens are given - order
2994 is user, group and password.
2996 Fix memory leaks in MARC record handling for ZOOM.
2998 New option for YAZ client, -k <kilobytes> that sets
2999 maximum record size. Similar to -k option for generic frontend
3000 server and yaz-ztest.
3002 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3004 Prefix query parser reports "fail" when bad attribute set is given.
3006 Fix in MARC decoder. Proximity logging. Fix for attribute set
3007 in scan handler for server. Patches by Shigeru Ishida.
3009 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3012 Configure option --with-openssl=<dir> now works when a directory is
3013 specified. Patch provided by Morten Bogeskov.
3015 New option for YAZ client, -u <auth>, that sets authentication.
3017 ZOOM fix: error information was sometimes "missing", since error
3018 was cleared/reset too when it shouldn't.
3020 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3022 --- 1.8.4 2002/01/04
3024 Scan for ZOOM API. New object ZOOM_scanset. New functions
3025 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3026 ZOOM_scanset_destroy.
3028 New ZOOM function, ZOOM_connection_last_event, that returns type
3029 of last event (such as "receive data", "send data", "apdu received",
3032 New ZOOM option, schema, that specifies schema for retrieval.
3034 New CCL feature. Qualifiers can be aliases for one or more
3035 other qualifiers (if more than one is given, OR is used).
3037 ZOOM uses named result sets if target supports it.
3039 Two new YAZ client commands: . (dot, which sources a script of YAZ
3040 client commands), and ! (to execute shell command.). Implemented
3043 Working on Debian packages.
3045 --- 1.8.3 2001/11/19
3047 YAZ client enables named result sets only if target supports it.
3049 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3051 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3052 with key="host" to get same result.
3054 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3055 Function Z3950_resultset_record(s) returns references to records
3056 "owned" by resultset. To become owner use Z3950_record_clone.
3058 Function z_ext_record handles Extended Services. Thanks to
3061 --- 1.8.2 2001/11/12
3063 CCL Parser fix: ignore token comma when dealing with and-lists.
3065 Documentation updates for COMSTACK.
3067 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3068 Changed prototype Z3950_records. For some functions, int parameters
3069 were changed to size_t.
3071 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3074 New MARC decode/display function, marc_display_exl, which properly rejects
3075 non-ISO2709 records. YAZ client uses it.
3077 --- 1.8.1 2001/10/29
3079 Fix bug: local attribute set wasn't set correctly in PQF strings.
3083 * Old Z39.50 codecs no longer supported.
3085 Added ZOOM C binding. See http://zoom.z3950.org/
3087 Renamed states for COMSTACKs to avoid confusion with events.
3089 Implemented cs_look and proper cs_rcvconnect.
3091 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3093 Configure detects POSIX threads on OpenBSD.
3095 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3096 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3098 When error is returned from present handler, non-surrogate diagnostic
3099 is returned in present response (and fetch handler is no longer called).
3101 * Minor adjustments to pquery parser (PQF). Token characters may be
3102 escaped by using backslash (C-style).
3104 PQF parser allows string attribute values to be specified. For @attr,
3105 non-numeric characters after the equal-sign are treated as strings
3106 (e.g. @attr 9=title).
3108 CCL trunction character may be defined (@truncation in file)
3110 * function zget_ExtendedServicesRequest sets waitAction to
3111 waitIfPossible (was wait).
3113 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3116 CCL operator names may be set in field definition files (CCL_bibset).
3117 See ccl/bib1 for an example.
3119 Fixes in ASN.1 compiler for C++ compatibility.
3121 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3122 and "op_or" to avoid conflict with C++.
3124 Fixed problem with GNU readline detection on Redhat 7.0.
3126 Added step-size for Scan backend handler.
3128 Fixed bug that made the frontend server crash when no attribute
3129 set was specified for scan.
3131 Front-end server automatically switches to original working directory
3132 when installed as an NT service. Previously -w had to be specified to
3135 Added extended attributes for retrieval module (data1), so that data1
3136 records carry d1_readXML/SGML attributes. d1_read also supports
3137 null-data rules ( <tag/>)
3139 On UNIX when POSIX threads are available, a separate library libyazthread
3140 is created. Programmers should link with that library and the yaz library
3141 when using threads. The reason for the split was that some applications
3142 on Linux, such as Apache, doesn't work well when using shared objects that
3145 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3146 (or any frontend server) in SSL mode by specifying ssl: followed by
3147 address. Only tested on UNIX.
3149 Added feature for CCL module. Virtual structure s=al or s=ol generates
3150 and-list and or-list respectively instead of phrase search.
3154 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3155 log_mask_str. This was done to avoid name conflicts with other libraries
3156 (such as other PHP extensions).
3158 Added raw OID member for preferred record syntax (request_format_raw)
3159 and returned record syntax (output_format_raw) for backend fetch method.
3161 Config file yaz-config now accepts options so that it returns specific
3162 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3164 Shared library support for UNIX using GNU libtool.
3166 * Modified backend interface. Request/Response struct's replaced by
3167 one read/write C struct. For example bend_fetchrequest and
3168 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3169 Every handler - even search has to be registered in bend_init
3170 handler. This means that the YAZ library no longer refers to
3171 external functions and it makes it possible to make the whole
3172 thing a single DLL/SO.
3174 Added Segment handler for backend server.
3176 Added Zmbol/Zebra administrative functions to YAZ client.
3178 Threaded frontend server on UNIX (when POSIX Threads are available).
3179 Starting the server with option -T enables multi-threading.
3183 Added configure option --enable-comp/disable-comp to control use
3184 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3185 located in sub directory asn.
3187 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3188 in ${exec_prefix}/bin along with the other programs yaz-client and
3191 GNU automake used to maintain makefiles.
3193 Added several OID's.
3195 Changed retrieval module so that we can load records with no abstract
3196 syntax defined. Tagpaths in these records are fully composed of string
3199 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3203 On UNIX, the generated makefile now supports a proper 'make install'.
3204 The prefix can be set via GNU configure to set the install location
3205 (default is /usr/local).
3207 * YAZ programs client and ztest were renamed to yaz-client and
3208 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3209 locations, such as /usr/bin,/usr/local/bin,etc.
3211 * YAZ Header files were moved from include to include/yaz. YAZ Header
3212 files are referred to as include <yaz/log.h> rather than <log.h>.
3213 The YAZ include path (-I ..) is therefore the same as before. Programmers
3214 should update their #include statements or use -Ipath/include/yaz
3215 instead. The main motivation for doing this change is that YAZ header files
3216 can be installed in "standard" locations /usr/include,/usr/local/include
3217 without introducing conflicts, since ALL YAZ header files are stored
3218 in subdirectory yaz (under /usr/include for example).
3220 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3221 rather than project/workspace files. We switched because project files
3222 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3225 Changed name of logging function, logf, to yaz_log, to prevent name
3226 clash with some math-log functions. The YAZ header log.h defines logf
3227 to yaz_log (#define) so there should be no incompatibilities by this
3230 Added bend_start/bend_stop handlers for server. These handler are
3231 called on start/stop of server. For windows they are called whenever
3232 a service is started/stopped.
3234 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3235 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3236 in util/yc.tcl. The auto-generated C code structures are, in a few
3237 cases, incompatible with the old decoders. There are differences in the
3238 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3239 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3240 The preprocessor variable ASN_COMPILED is defined when the compiled
3241 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3242 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3243 wish to use the old encoders/decoders you can specify --disable-yc
3246 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3247 version so that it supports both new - and old version of DB Update
3249 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3250 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3251 change. The name parameter can be set to 0 in which no name is specified
3252 for the construction. The macros odr_implicit and odr_explicit sets name
3253 parameter to zero for the construction involved. New macros
3254 odr_implicit_tag and odr_explicit_tag are similar to the others,
3255 except that a name parameter is added. For programmers' that don't use
3256 ODR they probably only need to change the call to z_APDU and z_External.
3258 Added access control facility by interfacing the TCP wrapper library.
3259 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3260 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3261 name of the daemon and enables the access control as specified in
3262 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3264 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3265 den Dool <H.M.vdnDool@kub.nl>.
3267 Added reference ID parameter to most functions in server API - refer
3268 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3270 Changed name of ccl library to libccl.a (was ccl.a).
3272 Fixed bug in decoder for Explain (Category TargetInfo).
3274 Added support for GNU readline in client. Thanks to Jacob Poulsen
3275 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3277 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3278 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3279 IMPLEMENTATION! This change was made to the development version before
3280 the ZIG decided to retract the amendment. If any users MUST be
3281 compatible with the original Update definition, PLEASE CONTACT US, and
3282 we will include a separate definition corresponding to the old Update
3283 ES. Note that because of the change to the ASN.1 of the
3284 TaskPackageRecordStructure we cannot define a single structure that
3285 will support both versions.
3287 * Added const modifier to buffer parameter for some ODR/BER encoding
3288 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3289 completeWAIS, odr_dumpBER.
3291 Fixed bug in client.c which caused a crash when a scanResponse didn't
3292 contain positionOfTerm.
3294 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3295 * will cause an error in a client if a non-YAZ target sends both a
3296 * list of Scan entries and non-surrogate diagnostics.
3298 Retrieval module enhancements. Tag sets may be typed in the reference
3299 to it. From the .abs-file the "tagset" directive takes a third optional
3300 integer type for the tag set referenced. From a .tag-file the "include"
3301 directive takes a third optional type as well. The old "type" directive
3302 in the tag set itself is still recognized but acts as the default type
3305 Backend interface change. Individual Scan terms returned from bend_scan
3306 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3307 in include/backend.h.
3309 Retrieval module enhancements. Multiple tag sets and attribute sets may
3310 be specified in abstract syntax specs. Revised the error/warning for
3311 logging messages reported by the retrieval module when reading the
3314 Object Identifier system (oid_..) changed. The API is backwards
3315 compatible but the oid-routines now allocates new OID's when needed.
3316 Raw OID's may be specified in oid_getvalbyname.
3318 YAZ now uses GNU configure to generate Makefile(s).
3320 * Minor changes in some of the member names of DeleteResultSetRequest and
3321 DeleteResultSetResponse. See include/proto.h.
3323 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3324 and added member 'languages' in TargetInfo (which was missing).
3326 Changed the way attribute sets are handled in the retrieval
3327 module. These are now cached, just like the abstract syntaxes
3330 Changed YAZ so that it links with compiled ASN.1.
3332 Added Explain-schema definitions and mapping routines. The following
3333 Explain categories have been implemented: AttributeDetails,
3334 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3336 Fixed minor bug in Windows version of Server Library.
3338 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3340 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3342 Added EXTERNAL: UNIverse Resource Report (non-standard).
3344 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3345 ENUMERATED and SET OF.
3347 * Added 'const' to some of the char pointer arguments for the
3348 functions, data1_read_node, data1_getelementbytagname,
3349 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3352 Fixed bug in data1_insert_taggeddata - the last_child member of
3353 parent wasn't initialised.
3355 * Changed data1_read_record and data1_read_node so that the supplied
3356 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3357 doesn't refer to any parts of the "SGML"-buffer.
3359 Fixed bug in server library (Windows version of statserv_remove).
3361 * Changed code so that it compiles as C++. The type definition
3362 of Odr_fun which is a member of Odr_arm was changed. The result is,
3363 that an explicit typecast is needed for the fun pointer when
3364 using Odr_arm - as in:
3365 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3367 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3369 Implemented the new structured date and time definition as approved
3370 by the ZIG. Added schemaId element to the specificTag in Espec-1
3371 (also approved at the last ZIG). Thanks to RVDM.
3373 Added some Object identifiers (RVDM).
3375 Changed the Update Extended Service (RVDM).
3377 Added command "refid" to client which specifies referenceId for
3378 the following requests.
3380 Implemented extended service handling for server. See ztest.c
3381 for an example as well as backend.h. New handlers are registerd
3382 in the Init handler.
3384 * Changed interface for sort in server.
3386 Added new members to statserv_options_block. It allows a server
3387 to read options from another source than just the command line. Thanks
3388 to Charles Woodfield.
3390 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3391 renamed to zboolean. Some C++ compilers complained about the name.
3393 Minor changes to gils.abs. Added index 's' (sort) on title
3394 and date/time-last-modified.
3396 --- 1.4pl2 1998/1/30
3398 Fixed bug in server library regarding inetd mode (-i). This bug
3399 was introduced by release 1.4.
3401 --- 1.4pl1 1998/1/29
3403 Added sort facility in client and backend server interface.
3405 Fixed problem with dependencies in Makefile(s).
3407 Fixed bugs for encoders/decoders of extended services and
3410 Implemented sub-tree feature for schemas. Sub-trees are
3411 referenced in *.abs-files. See explain.abs for an example
3412 of the use of this feature.
3414 Modified bib1.att; local attributes for ANY didn't include
3415 ANY itself (only affects use of the retrieval module).
3417 Fixed bug in plain SGML reader in function data1_read_node:
3418 tags with prefix "var" was incorrectly interpreted as variants.
3420 Added feature "sub-schemas" to enable references to - and definitions
3421 of - group of elements.
3423 * Removed member parent from type data1_element (in data1.h).
3425 Implemented function odr_nullval() that returns the value of
3428 * Removed member num_children from data1_node (in data1.h).
3430 Made NT service interface part of the server library. The
3431 function statserv_main uses the NT service when required and
3432 calls the statserv_start / statserv_close routines.
3434 Routine zget_SearchRequest and zget_PresentRequest fills
3435 resultSetName/Id member with "default" instead of "Default".
3437 Fixed memory leak in server. Request queue member wasn't freed.
3439 Fixed nmem_exit so that memory is freed.
3443 Revised the CCL parser utility to be thread safe.
3445 Added function, oid_ent_to_oid, to replace the function
3446 oid_getoidbyent, which is not thread safe.
3448 * Added nmem_init and nmem_exit to initialize and release
3449 NMEM resources. Function nmem_init should be called once in the
3450 initial thread before NMEM/ODR is used. statserv.c and client.c
3451 have been changed accordingly. The change was necessary to make
3452 NMEM thread safe. The NMEM memory pool is shared amongst threads
3453 in a process. Unix-based applications will still work fine without
3456 Added NT Services interface for the the Z39.50 (statserv) Server.
3457 Refer to the ztest.c source on the usage.
3459 Windows 95/NT port using MSVC5.0. Project files are included in the
3462 * Defined new 'global' handle for the retrieval (data1) system. The
3463 new handled, data1_handle, describes the state of the data1 system.
3464 This handle is passed as first argument to virtually all
3465 data1 related routines. The functions data1_create and data1_destroy
3466 creates and destroys a data1 handle respectively.
3468 Added ODR encode stream member to all backend request structures
3469 init, search, scan etc. This stream should be used to allocate all
3470 memory used for the response when thread safe operation is needed.
3472 Changed the comstack utility, cs_addstr, to be thread safe. The
3473 returned hostname string returned by the function is now part the
3476 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3477 function. The cs_straddr takes a COMSTACK handle as argument, so this
3478 function must be used after cs_create and before bind/connect.
3479 This function is thread safe.
3481 Moved test server to 'ztest' directory - generic server code still
3482 in 'server' directory.
3484 Made prefix query (pquery.c) utility thread safe.
3486 Added new function modifier YAZ_EXPORT to 'export' public DLL
3487 functions when using windows (see include/yconfig.h).
3489 Added definitions to the OID database (util/oid.c) (RVDM).
3491 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3493 Added call to ccl_rpn_delete in client program.
3495 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3496 release of RPN structure.
3498 Added support for C++, headers uses extern "C" for public definitions.
3499 With input from RVDM.
3501 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3502 Thanks to Ronald van der Meer (RVDM).
3504 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3506 Added support for private extensions to the OID database
3507 (oid_setprivateoids()). Thanks to RVDM.
3509 Added optional, physical ANY (key replication)
3511 Fixed null-reference problem in GRS-1 output filter.
3513 Proximity operator added to Prefix Query Format (PQF).
3515 In test client command "base" accepts multiple databases.
3517 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3521 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3523 Smallish bug-fixes in the new encoders/decoders (explain).
3525 Bug fixed in DeleteRequest.
3527 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3529 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3531 Added SOIF syntax (using private OID for now) to retrieval module and client.
3533 Added Update extended service.
3535 Added SearchResult-1 additional info structure.
3537 Added optional CCL (ISO8777) interpreter as separate module. Available
3540 --- 1.2 1996/6/10 (1st anniversary release)
3542 Added Summary record syntax. Lightly tested.
3544 Added OPAC record syntax. Untested.
3546 Added ResourceReport service encoders/decoders. Untested.
3548 Fixed bug in z_Unit - wrong tagging on unitSystem.
3550 Fixed bug in the DiagRecs decoder.
3552 Added options for max PDU size and session timeout to frontend-server.
3554 Added documentation of query-language parsers and other supporting utilities.
3556 [frontend-server] Added Attribute set to the bend_scanrequest API.
3558 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3559 surrogate diagnostics were generated.
3561 [retrieval] Allow multiple local values for attribute.
3563 [retrieval] Allow multiple attributes per element in .abs files. index type.
3565 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3567 --- 1.1pl2 1996/4/10
3569 Minor changes, mostly specific to Zebra's requirements (retrieval)
3573 Repaired bug in frontend server when running multiple listening
3574 endpoints in dynamic mode.
3576 z_External() now won't break if a known, ASN.1 value comes encapsulated
3577 in an octet-string. The value will pass through unmodified in an Odr_oct.
3579 Added a bit of code to the demo client to decode & display
3580 ASN.1-structured records represented in the octet-aligned branch of
3581 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3583 Added z_ext_getentbyref() to the ASN module. Doc updated.
3585 * Completed the SCAN definition in the ASN module. This may break SCAN
3586 code based on older YAZ-versions at compile-time. The fix is easy -
3589 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3590 under the SCAN definition. Remember to initialize this, server-people.
3592 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3593 that this does not extend to ODR and ASN.
3595 Comstack allows insertion of established socket (primarily for
3596 inetd-operation of servers). Doc updated.
3598 Front-end server can now start from the inetd in TCP mode. Doc
3601 --- 1.0pl4 1996/1/24
3605 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3606 the rank and record number.
3608 Adjustments to the frontend server.
3610 Fixed diagnostic BER dumper. It ignored the file argument.
3614 Various changes to retrieval module.
3616 Changed the union discriminators of the protocol files from enums to
3617 ints paired with #defines.
3619 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3622 *Changed operator in the RPN structure to 'roperator', again to avoid a
3625 Fixed problems in Explain decoders/encoders.
3627 --- 1.0pl2 1995/12/6
3629 Memory bug in log module fixed.
3631 --- 1.0pl1 1995/12/5
3633 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3635 Bug in Explain DatabaseInfo module fixed.
3637 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3641 The shift to v1.0 signals that we now consider the *core* functionality
3642 of YAZ reasonably stable (the core being more or less equivalent to
3643 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3644 tested (Explain not at all - though that will happen soonish).
3646 Minor changes to code to support Windows port.
3648 Various minor changes after we're getting to use GRS-1 & co. more.
3650 Added Espec-1 format.
3652 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3653 of the protocol and it cannot be selected when encoding (maps into 'string'
3654 when decoding). Needed to talk to some servers.
3656 Demo client can request simple element set names.
3658 Added Diagnostic Format encoders/decoders.
3660 Added simple Close handling to frontend server (no hooks for resource
3661 reporting yet), and demonstration client.
3663 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3665 --- 1.0b3 1995/08/24
3667 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3668 handled incorrectly when records were requested in the searchResponse. This
3669 will only affect you if you use the frontend-server.
3671 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3672 Test-client will ask for and print GRS1. Ztest will return dummy records
3675 Added Explain encoders/decoders to the service-level API. Untested.
3677 Added Extended Services: Item Order encoders and decoders to the Service-
3678 level API. Untested. We could use a recent copy of the pertinent bits
3679 of the ILL protocol to add those bits.
3681 Added diagnostic format 1 encoders/decoders to the service-level API.
3684 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3685 odr_cons.c, which causes a more correct output.
3687 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3688 was always set to 0 when no records were requested in the searchRequest.
3690 * Added better external-handling. This shouldn't harm old code that
3691 *encodes* externals. It can break code that looks for a
3692 'single-ASN1-type' representation, since those types that are known
3693 are now decoded immediately. Look at the SUTRS sample code in
3694 seshigh.c and client.c. Documentation updated.
3696 Handling of structured records in bend_fetchresponse. Length -1 marks
3697 structured record, type is deduced from format field.
3699 --- 1.0b2 1995/06/27
3700 Fairly quick maintenance release to add SUTRS support.
3702 Fixed handling of SUTRS records in the demonstration client.
3704 * Added format field to the bend_fetchrequest and bend_fetchresponce
3705 structures of the backend API (frontend server). When the record is
3706 returned, the value of the format field is mapped to an OID. The
3707 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3708 of the record. The special value VAL_NONE in the bend_request means
3709 that no specific format was requested by the client. Documentation
3710 updated accordingly. Test server (ztest) will return a fixed dummy
3711 SUTRS record if your client requests SUTRS.
3713 Documentation updated accordingly.
3715 You can now set external libraries and RANLIB support in the top-level
3719 First public release.
