1 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
2 This change makes many type-casts redundant, and, thus simplifies code.
4 Remove member 'size' from Odr_oct.
6 Slim down the public part of 'struct odr'. Most elements are not part
9 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
10 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
11 In particular facets are supported in both client - and server side.
12 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
13 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
14 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
15 both request/response). This is what a search handler in the GFS
16 will see (regardless of whether operating in SRU mode or Z39.50).
18 Changes to the srw.h (SRU/Solr) definitions include:
19 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
20 (char*), which replace union query and query_type (int). This is because
21 SRU 2.0 supports a queryType parameter. This also means that, to carry
22 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
23 x-pquery=PQFstring (extention parameter). The extension parameter
25 - New element, packing, that has information about SRU
26 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
28 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
30 New element, packing, in Z_SRW_explainRequest.
32 New elements in Z_SRW_scanRequest, queryType and scanClause.
33 These replace query_type and scanClase untion. This is similar to what
38 GFS: log when closing down - at least SIGTERM YAZ-684
39 Also change formatting WRT PID logging a bit.
41 Improve display of MARC records with multi-byte subfield IDs YAZ-695
42 In some rare cases subfield identifiers are multi-byte characters.
43 This will try to deterime length of those and split accordingly.
44 This affects display in line mode as MARCXML/MarcXchange. The encoding
45 of ISO2709 is the same.
47 Change inp argument to const for yaz_read_UTF8_char.
49 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
51 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
53 Better check of marc leader info YAZ-691
54 Problem is that some systems generate MARCXML/MarcXchange with
55 funny headers. These will not work if encoded as ISO2709.
56 Some tests produce new output, due to updated warning messages
58 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
60 yaz-client: display MAB records YAZ-689.
61 Thanks for Heiko Jansen for this patch.
63 New utility z_get_HTTP_Response_server which allows both HTTP server name
64 and HTTP server URL to be given in response.
66 Debian: do not depend on obs tcl8.3.
68 Debian: do not depend on obs libicu36-dev.
72 GFS: pass additionalSearchInfo to search memeber search_input if
73 given. Otherwise pass otherInfo. Request for facets and other search
74 related things will be passed there in future versions of YAZ.
76 New ZOOM setting, authenticationMode, which allows authentication
77 paramters to be encoded in the URL rather than via HTTP Basic auth.
80 rpn2solr: fix nested AND/OR handling. YAZ-685
82 Add comparison routines for some Z-types, such as NamePlusRecord,
83 RPNQuery, Query, RecordComposition and OtherInformation.
87 Don't decode MAB as MARC. Just like we don't attempt to decode
88 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
90 CCL: allow quoted terms for date ranges. YAZ-681
92 Introduce ccl_parser_qual_search. This function makes old function
93 ccl_qual_search, from YAZ 2, available again.
95 Add yaz_facet_list_to_wrbuf. YAZ-683
99 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
100 schema was given for search. YAZ-675
102 Add Solr date range searches. YAZ-621
104 --- 4.2.65 2013/08/22
106 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
108 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
110 ISO2709/MARC parse most octet aligned records; not just those that
111 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
112 MARC parse more records instead of just dumping as is. YAZ-670
114 ZOOM: proper caching for variations of record schema. YAZ-671
116 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
118 --- 4.2.63 2013/07/17
122 --- 4.2.62 2013/07/11
124 New utility z_get_HTTP_Response_details - an extended version of
127 New utility yaz_url_get_error which returns error message of last
128 failed yaz_url_exec call.
130 yaz-url and url functions: allow max HTTP redirects to be controlled.
132 New functions yaz_file_glob2, yaz_xml_include_glob.
133 These functions takes a flags parameter, which, for now only controls
134 whether to fail inclusion of a non-existing file (without glob
135 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
137 --- 4.2.61 2013/06/20
139 For MARC XML parsing, allow record without leader. A fake/default leader
140 is inserted and a warning is tagged with the record.
142 ICU: fix leak in in icu_iter_get_org_info.
144 --- 4.2.60 2013/06/14
146 ICU: fix bug in icu_iter_get_org_info (un-init variable).
148 --- 4.2.59 2013/06/11
150 Implement z_HTTP_header_remove.
152 --- 4.2.58 2013/06/11
154 ICU: Disallow 0 ptrs for some ICU string utilities.
156 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
157 returns original tokens (before normalization).
159 CCL: avoid z39.58/regex truncation when not needed. Apply only the
160 conversion of those masks, when absolutely necessary.
162 CCL: configurable masking character - @mask. Default masking character
165 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
166 full response anyway, so a Transfer-Encoding header will obstruct the
169 --- 4.2.57 2013/05/15
171 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
172 picking a socket. Problem is that some systems has IPV6 support, but
173 we can't create sockets for them, so we pick AF_UNSPEC first.
175 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
176 use content_len to determine resulting Content-Length in HTTP response
177 and NOT Content-Length supplied in headers by user.
179 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
180 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
182 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
185 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
186 with big endian and unsigned char (by default).
188 --- 4.2.56 2013/04/26
190 Fix yaz-client connect (crash in 4.2.55).
192 --- 4.2.55 2013/04/26
194 Fix proxy/host problem for ZOOM that could occur if unix sockets
197 New Debian package libyaz4-dbg.
199 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
200 differently in tcpip_close.
202 --- 4.2.54 2013/04/17
204 Windows installer of YAZ includes YAZ4J as a component.
206 CQL: allow "extra terms" again, by default. Thus, the CQL parser
207 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
208 and earlier. CQL parser may operate in strict mode where queries
209 not conforming to the standard BNF are rejected (syntax error).
210 Whether the CQL parser operates in strict mode is controlled with
211 cql_parser_strict . Strict mode enabled with option -S for utilities
212 cql2pqf and cql2xcql .
214 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
216 --- 4.2.53 2013/04/10
218 New charset, MARC-8c, which is like MARC-8 but allows control characters
219 0x01 through 0x1F, except ESC to be passed through verbatim.
221 Fix a problem with duplicate sub field character in MARC output. Problem
222 happened only when output was MARC-8 encoded.
224 --- 4.2.52 2013/04/03
226 yaz-ztest: Use hash for fake hit count. Before, random number was used.
227 This is problematic for unit tests using yaz-ztest. This patch also makes
228 a hash for CQL queries. For RPN, any term with a leading digit will be
229 treated as pseudu hit count (to force any particular hit count by a client).
231 yaz-ztest: return unique MARC dummy records. Beyond record offset
232 24, the author surname is patched with offset to make all records
235 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
236 on system wide default (/proc/sys/net/ipv6/bindv6only).
237 @4 binds to IPV4 only. @6 binds to IPV6 only.
239 Update CQL API documentation a bit
241 CQL: don't accept extra terms for queries. Makes the CQL parser
242 stricly conformant to the standard.
244 --- 4.2.51 2013/02/12
246 GFS: scan handler gets extra_args from request and may return extra
247 response data . That's for SRU only.
249 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
251 --- 4.2.50 2013/01/30
253 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
255 OPACXML: sync spelling of availabilityDate in XML to that of Schema
256 opaxxml.xsd. The schema had the correct spelling of this member always.
257 The ASN.1 was mis-spelled and still is (API change) - we are
258 not changing this. However, the OPAC to XML conversion had yet
261 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
264 New function, z_ext_record_oid_nmem, which is similar to
265 z_ext_record_oid but takes NMEM rather than ODR
267 --- 4.2.49 2013/01/18
269 ICU: New conversion element 'join' which joins tokens into one
270 with a custom character given by rule attribute.
272 --- 4.2.48 2013/01/10
274 New GFS search member: present_number. This is a hint to the
275 search handler how many records are going to be fetched immediately
276 following search. There's no guarantee that it's going to be the case,
277 since it depends on hit count (for Z39.50 piggyback) and whether errors
280 Make a few functions static (private). The functions getbyte_stream,
281 ungetbyte_stream and yaz_gets are now private. They were never declared
284 yaz-marcdump: exit(5) for serious decoding errors
286 ISO2709 decoding: be more picky WRT header
288 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
289 was only used as to indicate that next-result-set-position should be
291 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
292 Based on patch from Ashley Sanders.
294 Make some functions static/private in PQF parsing. Those functions were
295 never declared in a public header and so should not be in use by
296 applications based on YAZ.
298 --- 4.2.47 2012/11/23
300 ZOOM: special options to control APDU logging.
301 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
302 logging of APDUs until "saveAPDU" option is set again. If logging is
303 already enabled the effect is that current APDU buffer is cleared.
304 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
305 logging (default behavior on new connection).
306 The APDUs sent/received can be obtained by using
307 Using ZOOM_connection_option_get(c, "APDU") or
308 ZOOM_connection_option_getl(c, "APDU", &l).
310 GFS: relay implementation_version from backend
311 From 3.0.40 and later, implementation_version from backend was
312 not used in init response at all.
314 --- 4.2.46 2012/11/15
316 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
317 mode at all. Probably never did.
319 Make a new version of ztest.pem that, at least, is not expired.
321 --- 4.2.45 2012/11/13
323 Fix description of CCL directive 'case'.
325 More tight checking of form arguments (yaz_uri_to_array). Makes
326 YAZ better at rejecting big and/or bad POSTs.
328 SRU decoding does not report more than up to 10 invalid arguments.
330 rpn2cql: less quotes in generated terms. Semantics unchanged, but
331 it's prettier this way.
333 --- 4.2.44 2012/10/25
335 New utility yaz_decode_init_diag. Defined in proto.h.
337 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
338 given for unix local socket.
339 The COMSTACK string for doing so is:
342 unix:/myfile:tcp:localhost:9999/mybase
343 unix:/myfile:localhost:9999/mybase
344 unix:/myfile:http://fakehost/mybase
346 debian: Use dpkg-buildflags in build process.
348 --- 4.2.43 2012/10/19
350 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
351 global's SRU service uses a recordPosition scheme starting from zero.
352 First record's position should be one
353 according to the standard.
355 --- 4.2.42 2012/10/18
357 Allow more namespaces for SRU. This is to allow, for example, an
358 incorrect namespace returned from server
359 http://services.igi-global.com/sru .
361 Minor fixes for compilation on Windows.
363 --- 4.2.41 2012/10/11
365 daemon: log total number of bad signals from child on stop so that it
366 is more easy to spot problems with child worker processes.
368 retrieval: empty backend name attribute omits element set
369 from being used in retrieval.
371 --- 4.2.40 2012/10/04
373 Implement Solr sort strategy "solr", similar to sru11 sorting.
374 This will implement the correct parameters on Solr requst to do
377 --- 4.2.39 2012/09/28
379 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
382 MARC: Extra/missing indicator handled for MARCXML.
383 The indicator length is given in header and is the same for the
384 whole record. If attributes ind1, ind2 are missing, then content
385 character defaults to blank. Extra indicator attributes (beyond)
386 indicator length are treated as an error.
388 Reformat: delete trailing whitespace
390 --- 4.2.38 2012/09/17
392 MARC: fix non-ASCII characters for leader. This is to ensure we can
393 generate XML in UTF-8.
395 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
396 in one node with structure word.
398 --- 4.2.37 2012/09/04
400 yaz-json-parse: JSON output may be pretty printed by using option
403 Increase default value of max message for Z39.50 Init for GFS, ZOOM
404 and yaz-client. Old value was 1 MB. New value is 64 MB.
406 --- 4.2.36 2012/08/22
408 yaz-client: don't display bogus records from SRU servers. Some SRU servers
409 return more records than given by *maximumRecords*. Skipping those in
412 record_render: simplify buffer return handling and fix at least one bad
413 memory reference, that broke the test_embed_record sometimes.
415 Allow http://user:pass@host notation for yaz_url_exec.
417 zoomsh: allow shell command to be executed. Via the system(3) call.
419 yaz_poll: Allow num_fds == 0
421 yaz-client: fix bad encoding of "itemorder item". The itemorder
422 item <no> - command forgot to use length of encoded Item Request
423 package. Error present since YAZ 3.
425 yaz-ztest: fix bad usage of session handle. Bug was introduced when
426 result sets were saved (271a9c83).
428 SRU recordPacking: guess record packing in response rather than looking
429 at the recordPacking element which, OF COURSE, changed semantics in SRU
432 Decode SRU 2.0 responses. The official namespace for responses, according
433 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
434 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
435 nature.com's server, however, usee namespace
436 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
437 we are now using a glob-expr to match up the namespace. ZOOM C and
438 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
439 I can not find a single real example showing the "real" namespace in
440 the documentation from OASIS. The namespace for requests is different
441 from responses, but this is not added to YAZ yet, when we don't encode
444 --- 4.2.35 2012/06/26
446 zoom/record_render: add support for Base64 decoding fo MARC records
447 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
448 which will decode base64 + ISO2709 marc-8 encoded material from text node
451 --- 4.2.34 2012/06/07
453 Add missing definitions ZOOM_resultset_get_facet_field_by_index
454 and ZOOM_resultset_facets_names.
456 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
459 Change APDU dump printing to avoid long leading blanks. For levels 16
460 or larger the level is shown and the indentation is truncated but
461 recursed with modula 8. This makes it still reasonable easy to read
462 - even for nested BER dumps.
464 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
465 return 0 (incomplete package) in case where the BER package was
466 considered too nested (return value of -2).
468 dumpber: lines of level 15 are not indented further. Two spaces per
469 indentation; indentation 15 or more is indented to a fixed indentation
470 and augmented with a level=<no> indication.
472 zoomsh: increase max size of command+args
474 GFS: No limit in RPN buf size in CQL to RPN conversion.
476 --- 4.2.33 2012/05/09
478 New function for daemon utility, yaz_daemon_stop .
480 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
482 --- 4.2.32 2012/04/25
484 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
485 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
487 --- 4.2.31 2012/04/23
489 YAZ daemon utility relays SIGUSR1 to child process.
491 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
492 would result in en empty database list - which in turn would result in
493 encoding failure for search.
495 Fix reading beyond string in yaz_sort_spec.
497 --- 4.2.30 2012/04/11
499 Add two new SRU diagnostics:
500 236: Access to specified database denied
501 1015: Init/AC: Maximum number of simultaneous sessions for Userid
503 Document the very useful ZOOM-C option "apdulog".
505 CQL to RPN: term may be passed through verbatim. This is enabled with
506 truncation.cql . The assumption being that the term is already CQL.
508 --- 4.2.29 2012/03/20
510 record_conv: leader spec may be given for marc element.
511 The leader spec is given as attribute leaderspec for element marc.
512 For example to convert a MARC21 record from MARC-8 to UTF-8:
513 <marc inputformat="marc" outputformat="marc"
514 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
516 record_conv: allow user-XSLT params. For example:
517 <xslt stylesheet="MARC21slim2DC.xsl">
518 <param name="myparameter" value="myvalue"/>
519 <param name="otherparameter" value="othervalue"/>
522 record_conv: fix error handling for missing marc charsets.
524 CQL: fix extra terms in wrong order.
526 --- 4.2.28 2012/03/06
528 record_conv: modify new API for conversion types. The conversion types
529 may be passed in new functions yaz_record_conv_configure_t and
530 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
532 Avoid mixed statement/variable declare; fixes compilation with Visual
535 --- 4.2.27 2012/02/28
537 Add non-standard SRU diagnostic: 235: "Database does not exist".
538 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
539 Update SRU to Bib-1 diagnostic maps accordingly.
541 CCL: add two new diagnostics for unsupported masking. The new
542 diagnostics are: "Embedded truncation not supported" and
543 "Single charcacter mask not supported".
545 --- 4.2.26 2012/02/23
547 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
549 --- 4.2.25 2012/01/11
551 Build YAZ for Ubuntu Oneiric.
553 CCL: allow parantheses for proximity operands. For example CCL query
554 (a) % (b) is now allowed.
556 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
557 marked dead, rather then being destroyed. If not, the session memory is
558 being free'd before the search/scan handler is finished. Also destroy
559 'request' memory in request_release rather than in various places,
560 which resulted in leaks from time to time.
562 --- 4.2.24 2011/12/21
564 cql_sortby_to_sortkeys: honor sort prefix.
566 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
567 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
568 The rpn2cql family of functions now always returns quoted CQL terms.
570 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
572 --- 4.2.23 2011/12/15
574 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
575 sequence is treated as one. For example, &&a=b&&&c& is identical to
578 --- 4.2.22 2011/12/05
580 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
581 APDUs for a connection to a WRBUF.
583 --- 4.2.21 2011/11/23
585 Fix cql_sortby_to_sortkeys. Completely broken before.
587 Make CCL's @truncation work again.
589 --- 4.2.20 2011/11/09
591 New ZOOM connection setting: tproxy. It's like proxy, but does not
592 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
593 to set resolved address + port for a connection outside ZOOM itself.
595 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
597 --- 4.2.19 2011/11/07
599 Fix uninitialized variable in Solr spell support (could cause SEGV
600 for SRU response decoding).
602 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
603 back-end's addinfo through into the ZOOM response addinfo.
605 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
606 they are separated by a colon and a space rather than simply
609 --- 4.2.18 2011/10/28
611 Add support for Solr spell-checking/suggestions through ZOOM.
612 If a Solr target has been configured correctly for spelling-checking
613 and suggestions, these will now be returned on the ResultSet option
614 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
616 --- 4.2.17 2011/09/28
618 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
619 with a flag whether to substitute escape sequences or not.
621 --- 4.2.16 2011/09/22
623 Fix nmem_strsplit_escape to substitute escape char properly.
625 New option for zoomsh -e , which makes it abort on first error and
626 return process exit code to indicate success/failure.
628 YAZ options utility supports special option -- which makes all it treat
629 all following arguments as non-options.
631 --- 4.2.15 2011/09/16
633 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
634 searched if absolute filename is given.
636 Fix conv_xslt() error-reporting when stylesheet is not found.
637 (The value of fullpath is meaningless in this situation.)
639 --- 4.2.14 2011/09/07
641 Fix problem in CQL sort node creation: un-initialized memory.
643 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
644 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
645 CQL sortby depending on whether Type-1 or CQL is actually sent to the
648 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
649 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
651 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
652 will make it possible to use both single-character mask (#) and wildcard (?)
653 in CCL . Throw diagnostic for left truncation because that is not supported
656 --- 4.2.13 2011/09/01
658 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
659 cases using escapes (\-sequences) and masking.
661 PQF parse fix: A trailing backslash followed by end-of-string (\0)
662 would result in a read one byte beyond string.
664 rpn2ccl may use Z39.50 masking for terms (t=z).
666 ICU check fix. Don't include library -lCrun on Solaris, unless present.
668 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
669 not --cppflags (which seeems like an error in icu-config).
671 --- 4.2.12 2011/08/27 RPM package only
673 cql2ccl: fix conversion of terms: operator characters were not
676 --- 4.2.11 2011/08/25 RPM package only
678 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
679 CCL parser will map both # and ? to their regular expression
680 quivalents (. and .*).
682 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
683 of reserved CQL characters.
685 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
686 is, so that they are passed through.
688 --- 4.2.10 2011/08/24
690 ZOOM SRU mode: more aggressive re-connect.
692 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
693 made available as a utility function, declared in <yaz/logrpn.h>
695 rpn2cql_structure() supports proximity nodes (except that the Type-1
696 proximity node's "exclusion" binary is ignored, as there is no way to
697 express that in CQL). Fixes bug #4564.
701 Fix SEGV that could occur if set command of zoomsh was given without
702 value (2nd argument).
704 Fix SEGV that could occur if unsupported transport was given for
705 COMSTACK - say https (when SSL was unavailable).
707 Build yaz-url on Windows too.
711 New utility to get web content. Header is url.h. A command line tool
712 yaz-url is part of the distribution and packages.
714 Fixes for SSL COMSTACK (when gnutls is in use).
716 New functions yaz_base64{encode,decode}. Header is base64.h.
720 ZOOM C includes HTTP response buffer as additional info if it fails
721 to decode the SRU response.
723 Make wrbuf_json_puts available.
727 zoom: throw diagnostic for invalid value for option "sru". Before a
728 bad SRU request was sent.
730 Adding new utility wrbuf_vp_puts.
732 Add cclxmlconfig.obj to win/makefile. It was missing completely.
736 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
737 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
738 redirect was used at the same time.
740 MARC line mode decoding: be less picky about length given - first
741 5 digits of header that is.
743 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
745 Changes to decoding of SRU records: a record with recordPacking=xml is
746 modified with a new root element <yaz_record> if the recordData contains
747 multiple children elements. This is to make the record XML parseable
750 RPN to Solr conversion: encode special characters.
752 Generic Frontend Server: fix uinitialized member, stepSize.
756 Fix a bug in SRU decoding of records.. The database records stored
757 had un-initialized memory, but it would only be seen with yaz_record_render
758 and type_spec="ext" .
760 Fix a bug in ccl_qual_dup introduced in 4.2.3.
764 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
768 Add new utilities to convert from CQL to CCL . These utilities have
769 prefix cql_to_ccl defined in cql.h.
771 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
772 lead to memory heap corruptions when ICU utilities were in use.
776 Make compilation work without Libxml2.
778 yaz-client: remove redundant blanks in display of searchResult-1 term
783 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
784 resulting CQL node (tree) in a new node CQL_NODE_SORT.
786 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
787 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
788 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
789 Note that the CQL sortby spec is only converted when the GFS is already
790 converting from CQL to RPN (cql2rpn element).
792 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
793 specify whether to collapse delimitors or not. The existing nmem_strsplit
794 do collapse (collapse parameter = 1).
796 Windows installer: For NSIS, set InstallDir depending on x86/x64.
798 Rename internal func yaz_use_attribute_create. While non-static, this
799 function is not declared in a public header.
803 Add -lCrun when linking with ICU on Solaris.
805 More quicks character set conversions for OPAC records.
809 fix problem with record_render: records were converted (character set
810 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
814 SRU: add methods for handling DADS SRU-proxy facets.
816 Separate OPAC record character set for ZOOM_record. yaz_record_render
817 allows a character set given as charset=from/opacfrom,to where 'from' is
818 the character set of a bibliographic record, 'opacfrom' is character set
819 of OPAC record and 'to' is the target character set.
823 yaz-client: show may XML format records. Command show followed by 'format'
824 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
827 src/stemmer.c: Avoid using unnamed union. It is not supported by some
830 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
833 Update yaz.spec to operate on both SLES11 / Centos 5.5.
835 RPM: Release includes 'indexdata' name. Use indexdata in release name so
836 this package can be distinguished from other vendors.
838 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
839 as determined by configure
841 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
843 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
844 returns no error and no record, the present request is considered
845 partial (only a subset of the records could be returned by backend), and
846 so it is appropriate to set Present Status to partial-4.
850 Move yaz-config man pages to section 1.
852 More documentation about Solr.
854 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
855 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
856 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
857 peers on some Linux systems. However, in general that does not work
858 so YAZ can not rely on that to work. Debian changed behavior in this
859 respect from Debian lenny to Debian squeeze (still testing as of Oct
861 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
863 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
867 Fix yaz-config output: echo_source not set correctly by configure.
871 Solr Web Service support for yaz-client and ZOOM.
873 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
875 --- 4.0.12 2010/08/17
877 Z39.50 facet support. Facet specifications are passed for search in
878 other-information with ASN.1 as defined in facet.asn and OID
879 .10.1000.81.5 . Facets are expressed as an Attribute list as known
880 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
881 3 is limit (number of entries to get in response). yaz-ztest returns
882 dummy facets if a client asks for them.
884 --- 4.0.11 2010/07/09
886 CCL fixes: bug 2895 and bug 3539.
888 GR1-display: add comma in display - was removed by mistake in
891 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
893 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
895 --- 4.0.10 2010/06/18
897 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
898 result set from a connection. The result set will be on its own
899 thereafter; no operations on it will perform retrievals from a target.
900 Only cached copies are returned.
902 ZOOM C:fix case for HTTP servers responding with Connection:close.
903 Ensure that if there is a current task it is resumed (like fetching
904 more records in a result set) . Bug #3484.
906 PQF parser: use odr_atoi for Odr_int (not atoi)
908 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
909 values that contain any non-digits are treated as string attributes
910 (previously decoding only checked for leading character ([0-9]). PQF
911 encoding: attribute string values are not surrounded by double-quotes.
915 New utility for managing threads - thread_create.h.
917 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
918 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
919 but YAZ' implementation do.
921 Fixes for yaz_cond-functions on Windows 7.
923 DLL export more symbols.
925 zoomsh: show record do NOT render opac.
927 Remove *.la files from Debian and RPM packages.
931 Debian package libyaz-dev depends on libgnutls-dev again (was
932 removed in YAZ 4.0.6, but due to Libtool it is still needed
933 even though yaz-config do not list libgnutls libs).
935 ZOOM: Use only one WRBUF for returning string results for
936 ZOOM_resultset. Reduces memory usage for ZOOM in general.
938 ZOOM: ZOOM_connection do not use a shared pointer to
939 ZOOM_resultset after ZOOM_resultset is destructed by
940 user. Reverts to YAZ 4.0.4 behavior.
944 record-conv: fix problem with at least one XSL conversion -
945 due to probably incorrect usage of XML XSL documents.
949 Fix yaz-config for static mode and the use of SSL (gnutls).
953 Forward decl timeval struct in mutex.h and gettimeofday.h.
955 yaz-config: fix 'static' mode linking.
959 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
960 are wrappers for pthreads or Windows. For Windows these are put in
961 a separate DLL: yaz_cond4.
963 libyaz.la (whole source) is compiled with thread. If thread support
964 is enabled enabled, all source of YAZ is compiled with treading support.
965 This allows core utilities such as yaz_log to use thread facilities.
966 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
967 thread utilities. This commit moves mutex utilities (mutex.c) from
968 libyaz_server.la to libyaz.la.
970 yaz-json-parse displays leading text until error.
974 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
975 patch from Giannis Kosmas.
977 SRU: no longer URL encode SRU database. The URL for an SRU server is
978 a URL and such is alreeady encoded - at least when given with leading
979 http:// or https://. This reverts behavior to YAZ 3.0.50.
981 Support for new MARC XML notation TurboMARC which like MARCXML is a
982 complete representation of MARC/ISO2709.. This one, however, is more
983 compact and allows for faster processing with XSLT. TurboMARC can be
984 used in the marcdisp.h API, from the yaz-marcdump utility and from
987 yaz-ztest can be configured - via the database - to perform certain
988 delays when it performs operations search, present and single record
989 fetch. This allows testers to make yaz-ztest act as a real or even slow
990 Z39.50 server. Refer to the yaz-ztest man pages for details.
994 wrbuf_destroy allows NULL WRBUF passed to it.
996 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
998 Add ZOOM_connection_close.
1000 No fixed size buffers for ZOOM shell - bug #3257.
1002 tstodr: make it work on s390 platform.
1004 New icu iterator-functions. The new icu_iter-functions makes it possible
1005 to use ICU chains from many threads.
1007 yaz-client: better syntax check for show command.
1009 --- 4.0.1 2010/01/26
1011 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1014 New simple local-file XML include facility which allows file glob-patterns.
1015 Refer to yaz/xml_include.h.
1017 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1020 ZOOM_record_get supports new parameter "format" which makes it format XML
1023 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1024 JSONText in ECMA-262) is JSONValue, not JSONObject.
1026 --- 4.0.0 2010/01/20
1028 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1029 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1031 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1032 POSIX/Unix builds .so with major version 4.
1034 Remove old LOG_-defines from log.h. They have been obsolete and
1035 undefined by default for the last 5 years.
1037 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1039 GFS: Remove socket (int *fd) from search_rr handler. The socket
1040 descriptor ptr is a facility that allowed a search handler to supply
1041 a socket which would serve as a callback - when search was complete.
1042 This facility has now been in use for years.
1044 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1045 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1046 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1047 returns 'const char *' rather than 'char *. The returned string is
1048 read-only and should not be modified by applications. COMSTACK cs_close is
1049 now a void function - it no longer returns int. No applications check for
1050 the value and the implementations has always returned 0.
1052 ZOOM: use size_t for scan hit counts and str size. Functions
1053 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1054 occ (hit count) and len (string length) are now of type size_t pointer
1055 rather than int pointer. This is to be able to represent large hit counts
1056 and to also just to use the proper type for string length (strlen result).
1058 New JSON parser. Refer to include/yaz/json.h .
1060 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1061 Used to be int in some cases. Many wrbuf_-functions used to return an int
1062 indicating some length.. These return values were never used. And so they
1065 ODR: odr_malloc, odr_total now takes size_t for size.
1067 clone_z_type: fix leak; occurred for encoding failures.
1069 --- 3.0.52 2009/12/03
1071 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1072 bug was introduced in 3.0.51.
1074 --- 3.0.51 2009/12/02
1076 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1078 tcpip comstack: fix leak for getaddrinfo.
1080 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1081 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1082 Decoding of SRU "path" database is performed by private function
1083 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1084 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1086 yaz-client: honor base command for SRU. Change when database setting
1087 is applied for SRU and ensure it is kept when a connection is reset.
1088 Change also the way errors are displayed or SRU (decoding of packages).
1090 --- 3.0.50 2009/11/02
1092 Add support for extra request / response data for SRU codecs and GFS.
1093 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1094 for extra data response buffer and length. For the GFS, both request
1095 and response data (XML) is carried in extra_args and extra_response_data
1096 for the search handler. Patch by Ko van der Sloot.
1098 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1099 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1100 10010). This fixes bug #2113.
1102 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1103 cmdfile included a 'quit' command that would result in a memory violation.
1105 --- 3.0.49 2009/10/01
1107 Make a number of functions defined in xmlquery.c static. These have
1108 never been declared in a public header file (yaz/xmlquery.h) and was
1109 made public by mistake.
1111 Improve speed of character conversions (iconv utilities). This makes
1112 conversions from MARC-8 faster.
1114 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1115 unless type desired is "raw". This will prevent type "xml" from
1116 returning ISO2709 .. Which obviously can not be XML parsed.
1118 Fix memory leak in ZOOM that would occur if option apdulog was used
1119 on a re-used connection.
1121 Frontend server logs HTTP requests.
1123 Frontend server now sends Z39.50 close when it times out (sesssion has
1124 been idle for too long). Versions 2.0.30 and earlier also sent close.
1125 But due to a mistake this was disabled in all versions after that, i.e.
1126 the server would just close the socket immediately.
1128 yaz-client emits a better message when receiving an unrecognised
1129 userInformationField.
1131 Skip zero-length subfields when decoding ISO2709. This rare case happens
1132 if a record has two FS characters in a sequence. Without this patch
1133 there would be a reference beyond char array in using_code_len fragments
1136 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1138 --- 3.0.48 2009/08/28
1140 The show command offered by the zoomsh command now takes a 3d optional
1141 parameter type which is what is passed to ZOOM_record. If the type
1142 argument is omitted, "render" is used.
1144 RPN to CQL conv may use USE string attributes (bug #2978).
1146 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1148 --- 3.0.47 2009/07/08
1150 Function yaz_xml2query allows a diagnostic element in the PQF XML
1151 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1152 code and additional info respectively.
1154 The BER BOOLEAN is now the integral type Odr_bool which still happens
1155 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1156 typedef'd to Odr_int. This is still an integral 'int', but it may be
1157 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1158 ASN-1 compiler as well as programs has been updated to use the new types.
1160 --- 3.0.46 2009/06/08
1162 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1163 only the bibliographic record was rendered. For type=opac, an OPAC
1164 record is only returned if it is present.
1166 iconv: small fix for encoding of advancegreek.
1168 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1170 yaz-client: option auto_reconnect=on really reconnects.
1172 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1174 server: avoid null ptr ref for for yaz_poll errors.
1176 build: fix RPM build for RHEL 5.3.
1178 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1180 --- 3.0.45 2009/03/31
1182 Fixed bug #2709: TCP connect returns Invalid argument.
1184 Fixed compilation for mingw.
1186 Honor charset for raw records (ZOOM_record_get).
1188 Fixed use of errno for threaded mode that was seen on Solaris 10.
1190 Fixed argument passing with blanks in value for Windows Service.
1192 Disable YAZ' own log rotate by default (no 1 GB limit).
1193 The variable l_max_size which specifies the log file limit is set to 0
1194 (DISABLED): This is due to the fact that YAZ is most often deployed using
1195 logrotate. Also YAZ can not perform log rotate because of unsufficient
1196 permissions (setuid).
1198 --- 3.0.44 2009/02/17
1200 List supported encodings in man page for yaz-iconv.
1202 Fixed missing SSL libs for --libs output
1204 Re-established OID record syntax application-xml. Nobody should use it
1205 but we don't want to change soname because of this symbol being absent.
1207 --- 3.0.42 2009/02/02
1209 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1211 Added member named_result_sets for init handler struct for the GFS. This
1212 allows a server to disable named result sets.
1214 Removed OID record syntax application-xml.
1216 Added support for rule-based transliterator for ICU wrapper of YAZ.
1218 Fixed bug #1902: yaz-icu XML output.
1220 Make YAZ checks Emacs friendly.
1222 BITSTRING value shows value. Bug #2346.
1224 ISO2709 decoding: skip control characters from indicator data.
1226 Omit sort key by default in yaz-icu's output.
1228 Allow combined single char options (again) for YAZ' options function.
1230 Utility yaz-marcdump got option to display YAZ version (-V).
1232 Allow YAZ to use ICU 3.4.
1234 Added new ICU test case which illustrates removal of diacritics.
1236 --- 3.0.41 2008/12/29
1238 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1240 --- 3.0.40 2008/12/29
1242 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1245 Fixed bug #2352: yaz-marcdump crashes for certain record.
1247 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1249 Added support for Danmarc2 to UTF-8 conversion.
1251 Added support for ISO5426 to UTF-8 conversion.
1253 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1254 implementation version.
1256 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1258 --- 3.0.38 2008/11/10
1260 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1261 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1263 ZOOM C now interprets databaseName option for ZOOM connection as path
1266 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1268 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1270 Dummy Libxml2 types no longer defined in headers of YAZ'.
1272 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1275 --- 3.0.36 2008/09/26
1277 Various ODR chapter fixes.
1279 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1281 Added missing source for Windows compilation, mutex.c.
1283 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1285 For SRU connections in ZOOM all records up to "count" are now fetched.
1287 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1288 in Windows due to bad error handling for Libxml2.
1290 Added facility for sending arbitrary records (ASN.1 any) using
1291 ZOOM C's Extended service update. Patch by Sam Reynolds.
1293 New options for ZOOM C's connection, logapdu which makes ZOOM log
1296 --- 3.0.34 2008/06/18
1298 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1300 --- 3.0.32 2008/06/12
1302 Fixed memory violation that could occur when decoding UTF-8. This bug
1303 was only present in 3.0.30 of YAZ.
1305 --- 3.0.30 2008/06/06
1307 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1308 GNU TLS is used by default (if found).
1310 yaz-ztest returns OPAC records if a client asks for OPAC.
1312 Improved speed of MARC-8 encoding.
1314 Added support for lossy and loss-less MARC-8 encoding.
1316 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1318 Added new Windows Service wrapper (sc).
1320 yaz-client's itemorder command may now send a file.
1322 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1324 Added new function yaz_log_xml_errors.
1326 Allow (but warn) unknown XML attributes in MARCXML parsing.
1328 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1330 The UTF-8 to MARC-8 conversion now uses a different set of characters
1331 for Greek symbols. Bug #2120.
1333 --- 3.0.26 2008/02/21
1335 Added yaz_daemon (daemon.h).
1337 Fixed bug #2068: pkg-config trouble
1339 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1341 --- 3.0.24 2008/01/28
1343 Document --with-xml2 option.
1345 Added OPAC XML XSD (etc/opacxml.xsd).
1347 Allow glob mask for name attribute in retrieval element for the
1348 generic frontend server's retrieval facility.
1350 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1351 except POLLIN/POLLOUT.
1353 Fixed error handling in cs_listen. Bug #2037.
1355 --- 3.0.22 2008/01/20
1357 Fixed version in yaz/yaz-version.h.
1359 Fixed bug #2027: Crash when closing connection.
1361 Changed configure so that ICU support is only enabled if only ICU
1362 and Libxml2 is available (because the ICU chain is XML based).
1364 --- 3.0.20 2008/01/15
1366 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1367 is built. Only this DLL depends on the ICU runtime.
1369 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1370 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1372 Changed license of CCL module to 'Revised BSD'. After consultation with
1373 remaining members of the original EUROPAGATE consortium, we are re-issuing
1374 the CCL module without a separate license. The software was developed by
1375 Index Data as part of a research project. The special license was included
1376 to help feed usage information back to the project consortium to support
1377 project evaluation. At this time, the project consortium has long-since
1378 disbanded, and the majority of the original principals have retired. At the
1379 same time, we have significantly modified the software during the following
1380 years, to the point where very practically no original code remains. To
1381 simplify re-use of the software, we have contacted those members of the
1382 consortium who could be reached, and agreed to re-issue the module as a
1383 proper part of the YAZ package.
1385 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1387 CQL closer to being version 1.2 compliant. CQL also allows free-form
1388 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1391 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1392 bug could make Extended services handling crash in the ZOOM layer. This
1393 bug was only present in YAZ 3.0.18.
1395 --- 3.0.18 2007/12/19
1397 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1400 yaz-marcdump reads and writes collection wrapped records.
1402 Handle OPAC for record conversion module.
1404 Fixes for ICU wrapper.
1406 Allow ICU libs to be controlled with --with-icu .
1408 --- 3.0.16 2007/11/12
1410 Added yaz_poll which is a wrapper for select/poll. When poll is available
1411 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1412 sockets to be in use.
1414 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1415 functionality through an XML based configuration (ICU chain). This system
1416 is useful for search facilities such as Pazpar2 and Zebra that needs to
1417 perform tokenization of indexed material. The ICU code in a separate
1418 library libyaz3_icu.a.
1420 Added HTTP tunnel facility for COMSTACK, bug #1752.
1421 This is a facility that allows a Web proxy, such as squid, to tunnel
1422 Z39.50 traffic. This facility is "transparent" to must applications
1423 using YAZ. It's enabled by using pseudo transport connect: followed by
1424 the proxy address, followed by command, then follwed by he regular
1425 "virtual" addresss. For example,
1426 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1428 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1430 --- 3.0.14 2007/09/21
1432 Fixed bad memory reference in ZOOM_record - cuased by member not being
1433 initialized. This was a problem only in YAZ 3.0.12.
1435 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1436 fields were not removed.
1438 Changed the way C code is generated from codetables.xml. Made a MARC-8
1439 conversion trie for each characterSet section rather than codeTable.
1440 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1441 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1443 --- 3.0.12 2007/09/12
1445 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1446 from ZOOM_record_error).
1448 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1450 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1452 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1454 Better SRW-to-Bib-1 diagnostic mapping.
1456 ZOOM C and yaz-client announces SRU version 1.2 by default.
1458 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1461 Fixed in yaz_sru_decode to allow other version than 1.1.
1463 --- 3.0.10 2007/08/22
1465 Added support for SRU scan for ZOOM.
1467 Added support for the use of the older versions or Extended Service
1468 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1469 set to the version , 1=first, 2=second, 3=third. The third version is
1470 what ZOOM C has used so far. And that, obviously, is the default.
1472 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1473 therefore in Zebra and in SimpleServer-based applications). The new
1474 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1475 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1476 which is passed into the back-end search callback function.
1478 Added support for HTTP Basic authentication in clients: the SRU/W
1479 codec encodes the username/password elements of the PDU structure
1480 appropriately, and these may be set using the "user" and "password"
1481 options in ZOOM-C applications (the same options that are used for
1482 Z39.50 authentication).
1484 --- 3.0.8 2007/06/25
1486 Fixed bug #1208: SSL appears to be broken in ZOOM.
1488 Fixed bug #1206: Libxml2 include path weirdness.
1490 Added oid_name_to_dotstring.
1492 Allow elementSetName to be specified for ZOOM C record update.
1494 Allow waitAction to be specified for ZOOM C based for Extended Services.
1496 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1497 syntax OID. Bug introduced in YAZ 3 series.
1499 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1501 --- 3.0.6 2007/06/06
1503 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1504 directory. yaz-client now reads commands from file given by option -f
1505 if specified; then tries to read .yazclientrc in current directory.
1506 Failing that, it reads .yazclientrc from user's home directory.
1508 Added support for correlationInfo Note and ID for Record Update via
1511 Added yaz-client command querycharset which specifies character set for
1512 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1513 (termListAndStartPoint).
1515 Charset ISO5428:1984 is an alias for ISO5428-1984.
1517 Implemented a way to perform scan in a result set using Z39.50. This
1518 is achieved by attaching the result set name in the characterInfo
1519 (type InternationalString) of OtherInformation in the Scan Request PDU.
1520 The result set is identified in the otherinformation by the new OID:
1521 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1522 This allows for scan in result set and faceted search . Zebra did some
1523 of this in the APT term using attribute type 8 and value being result
1524 set. Using the OtherInformation approach for this is cleaner and easier
1525 to work with in proxies and the like. This facility can be used in
1526 yaz-client using new command setscan which takes a result set as first
1527 argument, start position (APT) as second.
1529 Changed decoding of SRU XML packed records to deal with servers that
1530 have recordData with XML data with multiple root nodes. Also make
1531 comparison for recordPacking case insensitive. Again, one server
1532 returns "XML" where others return "xml".
1534 For SRU responses allow Content-Type application/xml as well as text/xml.
1536 --- 3.0.4 2007/05/21
1538 Fixed bug in character set conversion of BER strings. Bug introduced
1541 --- 3.0.2 2007/05/08
1543 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1545 For OID class, use oid_class consistently.
1547 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1550 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1551 character set for bibliographic information interchange". By Giannis Kosmas.
1553 Added documentation on new OID API.
1555 --- 3.0.0 2007/05/02
1557 Changes to generic frontend server interface: added new member
1558 'query_charset' for bend_initrequest structure. A backend init handler
1559 should set this member to its native character set for query terms.
1560 When defined, the frontend server logic will announce this character set
1561 to a client if the negotiationModel bit is set by the client. All server
1562 implementors are encouraged to specify this. If a backend server does not
1563 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1565 Added CCL utility to remove terms (stop words) from resulting RPN
1566 tree. This is handled by functions with prefix ccl_stop_words_ .
1568 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1569 terms in RPN queries.
1571 Clean-up the CCL API. Moved some internal structures from ccl.h to
1572 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1573 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1574 This is replaced by ccl_parser_find_str which takes a string instead.
1576 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1577 libyaz.la is the core of YAZ except the generic frontend server and
1578 does not depend on POSIX threads anymore. libyaz_server.la is the
1579 generic frontend server facilities and uses POSIX thread functionality
1580 if available. The libyaz.la no longer depends on POSIX threads because
1581 the number of global structures is limited. NMEM no longer re-uses blocks
1582 between threads ; it simply free's memory immediately but allocates in
1583 "large" chunks as usual. We don't expect any performance penalties
1584 because of this. The yaz_log system is still using a global log_level so
1585 caution must be taken when modifying it with yaz_log_init_.. +
1586 yaz_log_mask_str. This, however, should not cause any trouble because
1587 these functions are called during initialization of application code
1588 anyway. `yaz-config --libs server` returns libs for server applications;
1589 `yaz-config --libs` returns libs for non-server applications.
1591 New OID database - with public definitions in oid_db.h. Removed old OID
1592 database including the head oid.h and definitions such as enum oid_value
1593 and struct oident. The new OID database uses the same string names as
1594 before but the 'protocol' is gone. There are now only two representations
1595 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1596 converts from string to OID; functions with prefix yaz_oid_to_string
1597 converts the other way.
1599 Change to emit_term() in CQL-to-PQF query translation: when a term has
1600 the /regexp relation modifier, do not process it for leading and
1601 trailing "^" and "*", which have quite different meanings in regular
1604 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1605 write handlers no longer carries a 'last' parameter. This will make
1606 yaz_iconv flush "less" characters. A flush is performed by call to
1607 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1609 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1610 removed, because function yaz_query_to_wrbuf does the same.
1612 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1613 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1615 Deprecated MARC utility functions removed.
1617 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1620 Branch split: YAZ_2_1_55_branch
1622 --- 2.1.54 2007/03/16
1624 Fix to ZOOM-C so that transparent reconnection is properly handled on
1625 connections that are in asynchronous mode.
1627 Fixed compilation on OpenBSD 4.0.
1629 Large strings in GRS-1 records are now properly displayed in yaz-client.
1631 Added character conversion support for "advancegreek"; based on patch from
1634 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1635 sequence is met. Before the error was not set so it would be unknown.
1637 Adjust yaz-marcdump MARC reader so that it skips until record separator
1640 --- 2.1.52 2007/03/07
1642 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1643 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1644 fd_set structure used as a bitmask for the FDs to be selected on.
1646 Using ACX_PTHREAD macro to check for POSIX threads.
1648 Fixed have-vsnprintf check.
1650 --- 2.1.50 2007/02/23
1652 Fixes for configure on BSD. Bug #900.
1654 Added snprintf/vsnprintf wrappers for systems that don't have
1655 limits (heavens forbid).
1657 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1658 created before all previous tasks were completed and removed from the
1659 task queue, the new task could be removed by a mistake.
1661 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1663 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1665 Fixed bug #832: Problem with MARC/charset in yaz-client.
1667 Fixed bug #668: save command line history for yaz-client.
1669 Fixed bug #830: pkg-config support.
1671 --- 2.1.48 2007/01/23
1673 Extended ZOOM result set options with two options that may be read by
1674 a client: resultSetStatus and presentStatus with values as specified for
1676 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1678 Fixed bug #827: Using SSL fails on Debian etch.
1680 Fixed bug #826: Weird looking chars for set of MARC records.
1682 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1683 that is treated as an ItemOrder with itemRequest being an XML document
1684 external. The value of "doc" is the content.
1686 Extended the GFS search facility. New member of bend_search_rr
1687 'estimated_hit_count' signals that hits is known to be an estmate
1688 (higher or lower than real hit count). New member 'partial_resultset'
1689 signals that the search was partial (hit count is lower or equal than
1690 real hit count). For Z39.50, the information is stored in resultSetStatus
1691 member of SearchResponse APDU. For SRU, the information is signalled
1692 via SRU diagnostic 59: "Result set created with valid partial results
1695 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1697 --- 2.1.46 2007/01/13
1699 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1701 Added ZOOM_connection_peek_event.
1703 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1704 the following new functions:
1705 ZOOM_event_nonblock, ZOOM_connection_process,
1706 ZOOM_connection_get_{socket,mask,timeout},
1707 ZOOM_connection_fire_event_{timeout,socket}.
1708 The existing blocking event handler, ZOOM_event, is a wrapper for the
1709 + blocking ZOOM_event_sys_{poll,select}.
1711 Implemented function ccl_xml_config which parses XML version of CCL
1712 configuration (bug #798).
1714 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1716 Added timings utility (yaz/timing.h)
1718 --- 2.1.44 2007/01/03
1720 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1723 Fixed bug #779: Rotation of apdu.log fails.
1725 Fixed for character set conversions:
1726 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1727 Honor G1 set in MARC-8 decoding.
1729 --- 2.1.42 2006/12/17
1731 Fixed bug #775: char conversion does not handle Alternative UTF-8
1734 Implemented function yaz_marc_read_line which parses MARC line format
1735 records. There is a wealth of formats out there. So far, this function
1736 reads line records produced by yaz_marc_write_line.
1738 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1739 more generic and easier to remember(!) options: -i format and -o format
1740 which specifies input format and output format respectively - where
1741 format is one of "marc", "marcxml", "line", "marcxchange".
1743 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1744 does not print anything except warnings for records.
1746 For yaz-marcdump, added support for MARC split into files (-s) with a given
1749 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1750 spec, at http://www.loc.gov/standards/sru/record-update/
1751 This has changed the binary layout of the following structs:
1752 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1753 bend_update_rr . Patch by Ko van der Sloot.
1755 Added GFS utility function bend_assoc_is_alive which returns 1 if
1756 association is still alive (client is connected); 0 otherwise (client
1757 closed connection). This allows busy servers to stop working for
1760 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1761 been a separate piece of software. This version of ziffy has been modified
1762 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1764 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1766 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1767 Client code may now interrogate options such as "init_opt_sort" to
1768 find out whether the server claims to support various options.
1770 --- 2.1.40 2006/11/27
1772 Added utilities yaz_{set,get}_esn to set/get element set name from
1775 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1776 of YAZ and has been so since YAZ 2.1.10.
1778 Implemented ZOOM_record_error which returns error information for
1779 record (surrogate diagnostic).
1781 --- 2.1.38 2006/10/31
1783 Updates for SRU Update by Ko van der Sloot:
1784 1. Changed name from "operation" to "action"
1785 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1786 versions in the code, marked as 'backward compatible'.
1787 3. Added diagnostics for SRU Update.
1789 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1791 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1793 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1795 For GFS, fixed problem with SRU diagnostic 'First record position out of
1796 range' being issued for 0 hits.
1798 zoomtst10 part of Windows Build.
1800 --- 2.1.36 2006/10/13
1802 Implemented yaz_filepath_comp which splits a path into file path
1803 components (required by Zebra 2.0.3+).
1805 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1806 BSD inspired license until now so this should not have any real impact on
1807 anybody. See http://www.opensource.org/licenses/bsd-license.php
1809 Fixed bug #687: Missing log lines.
1811 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1814 Fixed bug #689: SRU diagnostics to be added.
1816 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1817 whether a connection is idle (no more work do do).
1819 --- 2.1.34 2006/10/04
1821 Change type of optval from long to int for invocation of setsockopt with
1822 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1824 Added support for specifying the max log file size for the Generic
1825 Frontend Server. The size is given with option -r.
1827 --- 2.1.32 2006/09/21
1829 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1831 --- 2.1.30 2006/09/17
1833 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1836 Fixed bug in Generic Frontend Server that could cause a server to stop
1837 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1839 For the generic frontend server, the maximum record size is used as maximum
1840 size of incoming packages (SRU + Z39.50). The value until was previously
1841 only used in Z39.50 Init negotiation and, later, in a session controlled
1842 sizes of records returned. This is controlled using -k option. It can be
1843 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1845 --- 2.1.28 2006/09/04
1847 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1850 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1852 New option for yaz-marcdump -lpos=value which allows setting a portion
1853 of MARC header to a certain value.
1855 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1857 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1858 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1860 --- 2.1.26 2006/08/15
1862 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1865 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1867 --- 2.1.24 2006/08/08
1869 Fixed MARC ISO2709 encoding routines to deal with character set
1872 Minor changes to GFS logging. Database included in search request log
1875 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1876 cached/multiple records.
1878 Shared libraries are built by default on Unix+configure.
1880 Changed cql2pqf transformation to use a different evaluation order. The
1881 new order is: always, relation, structure, position, truncation, index
1882 and relationModifier. Old order was: always, relation, relationModifier,
1883 structure, index, position, truncation. Note that the the latter ones
1884 override former ones for identical attributes.. The new scheme means that
1885 it is possible to override any existing attribute with a relationModifier.
1886 And also that it is possible to override everything for the index rule
1887 (except the ones listed in relationModifier). No order is perfect but this
1888 one, we believe, covers more real cases.. The "always" should have been
1889 called "default", since the attributes there can be overridden with all
1892 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1893 compilation phase, but also for yaz-config --cflags output. This allows
1894 us to have public headers with Libxml2 stuff in them . It should also,
1895 eventually, make Libxml2 checks redundant in packages using YAZ, such
1898 --- 2.1.22 2006/06/15
1900 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1901 stored in uri, message and details.. Previously diagnostics were stored
1902 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1903 compatibility.. but he's probably the only one affected, so.
1905 Added support for CCL, compiled on the client side, in ZOOM-C. This
1906 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1907 input; the resulting query objects can be used for for searching with
1908 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1910 YAZ' configure searches for OpenSSL by default.
1912 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1913 SL_CTX_use_certificate_file. See
1914 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1915 for more info. Thanks to Ko van der Sloot.
1917 --- 2.1.20 2006/06/02
1919 Bug #600: SRU GET, POST support for yaz-client. Introduced
1920 command 'sru' which selects method SOAP/GET/POST.
1922 Allow missingValueAction to be specified for the sortspec string -
1923 function yaz_sort_spec. By default, the missing value action is null.
1924 Use ! to specify "abort". Use = followed by stringvalue to specify default
1927 Ensured that Present-handler (if defined) is called in GFS before any call to
1928 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1929 searchRetrieve requests.
1931 Documentation for YAZ is now based on the Docbook XML/XSLT using
1932 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1933 is no longer depending on jade/openjade or docbook-to-man scripts.
1934 PDF is no longer part of the distribution - but can optionally be
1935 made using DSSSL/jadetex or FOP.
1937 Added retrieval handling support in Generic Frontend Server to support
1938 conversion between MARC/XML as well as XSLTtransforms. See
1939 etc/yazgfs.xml for an example.
1941 Added Authentication support to Generic Frontend Server in SRU
1942 mode. Authentication using HTTP Basic is supported, as is the use
1943 of 'x-username' and 'x-password' parameters in the request itself.
1945 Added support for a new character set MARC8s identical to MARC8 except
1946 that it converts combined characters to single Unicode characters in the
1947 Latin-1 range (when possible).
1949 --- 2.1.18 2006/04/24
1951 ASN.1 compiler 0.4: generates brief Doxygen file header for
1952 generated .h/.c files.
1954 Utility yaz_iconv now supports conversion to MARC-8.
1956 New facilities for the MARC module. The reading - and writing of
1957 content are separate methods for the yaz_marc_t handle. The following
1958 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1959 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1960 format). Write functions have prefix yaz_marc_write_.. The existing
1961 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1962 available. Removed support for OAI-MARC and simplexml (not the
1963 simplexml from PHP5).
1965 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1966 to be returned for this connection.
1968 --- 2.1.16 2006/03/31
1970 Allow multiple languages and charsets to be specified with
1971 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1972 negcharset iso-8859-1,utf-8
1974 Translation of proximity nodes from CQL into PQF now works.
1976 Moved to automake 1.8, 1.9.
1978 Added function yaz_log_set_handler which allows a log handler to be
1979 installed. This handler will be called for all log messages. Output
1980 to file is also produced; but that can be disabled by passing NULL
1981 fname to yaz_log_init_file.
1983 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1985 For SRW (including GFS), accept application/soap+xml as content-type
1988 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1989 produces NO stylesheet reference even if a default stylesheet is specified
1992 --- 2.1.14 2006/03/14
1994 Updated Windows package to include yazd.dll + yazd.lib for the
1995 Development component.
1997 If the environment variable YAZ_LOG is set, then it is used as a
1998 string indicating the default level of logging to use if not
1999 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2000 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2001 used as before. So, for example, to omit warnings from YAZ logging,
2002 export YAZ_LOG=-warn
2004 cql_transform() now map structure and other attributes before indexes,
2005 so that index-specific structures and other attributes can override
2006 defaults. So now a combination of mapping specifications such as:
2008 index.dc.date = 1=date-modified 4=5
2009 does the right thing.
2011 cql_transform() now also respects the "always" mapping specification,
2012 which establishes an initial set of attributes to be used for all
2013 terms except where overridden by more specific attributes associated
2014 with the index, relation or modifier.
2016 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2017 which mode to use; one of "post", "get" or "soap" (SRW, default).
2019 Fixes for yaz_iconv routines: changed trie-based character set conversions
2020 to use only non-negative values for bit fields due to Sun's C compiler not
2021 supporting negative values.
2023 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2024 sequences where not read correctly. Fix by Rustam Usmanov.
2026 Updated win/makefile to use options, settings which makes things
2027 compile with VS C 2005.
2029 --- 2.1.12 2006/02/01
2031 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2033 In ZOOM socket code, use select instead of poll on MacOSX.
2035 ZOOM-C now support client-side compilation of CQL into RPN that is
2036 sent to the server, enabling CQL to be used against all Z39.50
2037 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2038 ZOOM_query object, and submit it using ZOOM_connection_search().
2039 The CQL-to-RPN translation uses a configuration file, the name of
2040 which must be specified in the Connection's "cqlfile" option.
2042 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2043 function, which takes as its start-term parameter a ZOOM_query object
2044 (which may have had either CQL or RPN set into it).
2047 --- 2.1.10 2005/11/29
2049 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2050 GFS to support this as well. Backend handler, bend_srw_update, does the
2051 update work. Code contributed by Ko van der Sloot.
2053 Allow retrieval of Search Result-1 information in ZOOM by the use of
2054 options that are attached to a result set. ZOOM documentation updated
2057 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2058 UTF-8 conversion. Patch by Raj Patel.
2060 Added option -m to GFS to control formatting of timestamps in log file.
2062 Added 'exit' as synonym for 'quit' in yaz-client
2064 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2065 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2066 for the new members. Patch by Ko van der Sloot.
2068 Added support for SRU POST. It is supported for content-type
2069 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2071 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2072 Instead make the library libyaz.la multi-threaded. Threading as a whole
2073 can still be disabled by configure option --disable-threads. Previosly,
2074 with older GLIBCs there were problems with MT libs under Apache. This
2075 has now been fixed a long time ago.
2077 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2080 CQL module modified to be case insensitive for relations/indexes/operations.
2082 Fixed bug in CQL transform code: incorrect value relationModifieder
2085 Added 'show all' command for yaz-client which retrieves all results
2088 Added new yaz-client, xmles, which takes a (private) OID and
2089 a document to be sent as an extended service request.
2091 Describe new yaz-client commands wait_response and set_auto_wait.
2093 Increase TCP/IP listener backlog from 3 (which I am guessing was
2094 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2095 that the socket will queue as many incoming connections as it's able
2096 to handle ongoing connections. In other words, it will never now
2097 refuse a connection that it would be able to handle merely because
2098 it's not got around to accepting() enough of the pending connections
2099 yet. This is the behaviour anyway under Linux, where the listen()
2100 argument is ignored; but not under BSD and on systems such as
2101 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2102 YAZ-based servers should now be uniform across operating systems in
2105 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2106 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2107 This allows yaz-marcdump to read large MARC batches (>2 GB).
2109 Modified all YAZ source files - except the source which is auto-generated
2110 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2113 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2114 corresponding to the existing *_setl() function. These allow option
2115 values containing arbitrary valuues.
2117 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2118 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2119 except that it returns an indicator of whether or not the sort
2120 criterion was accepted (0 for OK, -1 for invalid).
2122 --- 2.1.8 2005/06/07
2124 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2125 MARC output rather than returning "new" buffer.
2127 yaz-client warns about unknown init options.
2129 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2131 --- 2.1.6 2005/05/24
2133 Added support for SRW sort in Generic Frontend Server. Patch
2134 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2135 sortKeys - or NULL if none is provided.
2137 Fixed bug #307: It was impossible to specify indefinite/no timeout
2138 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2141 Added support for multiple languages and charsets to be specified in
2142 ZOOM. Each charset/language is separated by a blank. If negotiation is
2143 in effect in init-response, Option
2144 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2145 Code based on patch by Vasiliy Osadchuk.
2147 Fixed bug #306: infinite recursion that occurred when calling
2148 yaz_log_level_init as the first call (before other log level or
2151 Fixed bug in scan handling in front end server: if preferred-Position-In-
2152 Response was non-present, a NULL pointer referece was performed.
2154 --- 2.1.4 2005/04/26
2156 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2157 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2158 now defined for all those error codes. So instead of putting 109 in
2159 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2160 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2162 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2165 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2167 Program yaz-client now exits and produces an error message if multiple
2168 Z39.50 servers are specified on the command line (none or one allowed
2171 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2174 --- 2.1.2 2005/03/16
2176 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2178 Fixed bug #272: Preserve spacing for CCL terms.
2180 --- 2.1.0 2005/03/14
2182 Added support for virtual hosts and multiple backend servers for
2183 the YAZ frontend server. The configution is XML based and
2184 support specificition of CQL to RPN mappings and explain information.
2185 See section "Virtual Hosts" in the YAZ manual.
2187 Extended OPAC display utility. OPAC display utility renders
2188 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2189 to supplement yaz_marc_decode_wrbuf.
2191 Fixed a bug in MARC decoder that could caused it to crash for some
2192 invalid MARC records. More diagnostics and warnings where added in
2193 XML output (warnings, etc are stored in comments).
2195 --- 2.0.34 2005/02/08
2197 Fixes for UNIX domain sockets. Bug #261.
2199 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2201 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2202 Added yaz_marc_subfield_str which defines subfield lead string which is
2203 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2204 yaz_marc_endline_str which defines end of fields string used in
2205 YAZ_MARC_LINE format. Default string is newline.
2207 Experimental support for MarcXChange. This format can be produced
2208 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2209 http://www.bs.dk/standards/MarcXchange.xsd
2211 Added yaz-client commands scansize that sets maximum number of
2212 entries to be returned by scan.
2214 --- 2.0.32 2005/01/11
2216 Added support for SRW scan in yaz-client and Generic Frontend Server.
2218 * Added whereInList member to SRW Scan Term.
2220 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2222 Fixed NMEM system to return aligned blocks on the smallest boundaries
2223 that are suitably aligned for all possible types on the particular
2224 architecture YAZ is being built for.
2226 --- 2.0.30 2005/01/04
2228 Fixed numerious warnings that was issued with newer versions of GCC.
2230 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2231 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2234 Make YAZ Generic Frontend Server slightly faster.
2236 Enhance (and reduce) logging for Generic Frontend Server.
2238 Revert YAZ log system so that it flushes every write operation
2239 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2241 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2242 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2243 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2244 will effectively disable old definitions.
2246 --- 2.0.28 2004/11/09
2248 Added yaz_log_time_format which specifies log format using
2251 Added yaz_log_module_level which returns mask for a module. Value
2252 is non-zero mask a if module is enabled; zero if disabled.
2254 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2255 in include/yaz/cql.h.
2257 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2259 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2261 Fixed bug #172: RPM builds does not enable SSL.
2263 Doxyfile.in part of dist. Doxyfile generated by configure.
2265 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2266 are given and the corresponding component does not exist.
2268 Extend CCL documentation in YAZ reference. Describe r=r.
2270 --- 2.0.26 2004/10/01
2272 Fixed MARC->MARCXML conversion to properly deal with
2273 fields, subfields, indicators having non-ASCII characters.
2275 Fixed MARC->MARCXML conversion so that ASCII control characters
2276 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2279 Added YAZ GFS support for conversion from Z39.50 surrogate
2280 diagnostics to SRW surrogate diagnostics.
2282 Bug fix: YAZ GFS did not return schema in explainResponse.
2284 --- 2.0.25 2004/09/30
2286 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2287 now converts recordSchema to elementSetName as well as schema URI.
2289 Fixed bug in COMSTACK that prevented HTTP request packages from being
2292 --- 2.0.24 2004/09/29
2294 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2295 does not require white-space before and after the dash in a range, e.g.
2296 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2299 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2300 due to new GCC removing "redundant" code.
2302 Added yaz-client commands scanpos and scanstep that sets preferred
2303 position and step-size for scan.
2305 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2307 Added CCL utility ccl_qual_buf which parses one or more CCL
2308 spec lines in a buffer.
2310 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2311 of name and value - ignoring empty lines and comments.
2313 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2315 Added odr_get_element_path which returns current element path for an
2316 ODR handle. This utility is useful in error handling or user-defined
2319 Added ODR_PRINT utility odr_set_stream which is is a more generic
2320 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2321 to a write function and pointer to close function. The close function - if
2322 non-NULL - will be called during odr_destroy.
2324 Fixed bug in CCL parser where truncation char was not removed from
2325 right side when truncation=both was in effect.
2327 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2330 --- 2.0.23 2004/08/11
2332 Fix buffer overrun in CQL parser when dealing with proximity (%).
2334 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2335 to UTF-8/UCS conversion is now only based on codetables.xml.
2337 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2339 --- 2.0.22 2004/08/06
2341 Add support for more "commit changes" in ZOOM (uses Extended Services).
2343 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2346 Yet another small fix for configure of SSL.
2348 --- 2.0.21 2004/05/14
2350 Fix SSL libs for configure when --with-openssl=DIR is given.
2352 --- 2.0.20 2004/05/10
2354 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2356 SSL comstack now uses yaz.pem certificate file on server side
2357 by default. Certificate filename can be configured by calling
2358 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2360 Fix bug regarding multiple calls to ZOOM_connection_connect.
2362 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2364 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2365 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2367 ZOOM now allows inspection of X509 peer certificate for verification.
2368 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2370 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2371 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2372 as "modular" but it simplifies things.
2374 Added cs_get_peer_certificate to that returns peer X509 PEM.
2376 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2377 NULL if SSL is unavailable.
2379 Documentation about MARC decoding tools.
2381 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2383 --- 2.0.19 2004/03/30
2385 Rename CHANGELOG to NEWS to follow GNU style packing.
2387 Fix bug with missing initialization of member in init_diagnostics.
2388 This bug affects threaded version of GFS server.
2390 --- 2.0.18 2004/03/20
2392 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2395 Ensure zlib.dll is packed with Windows install.
2397 --- 2.0.17 2004/03/17
2399 Fix encoding of xsd:string to use text instead of CDATA.
2401 Fix endless loop in CQL parser with unbalanced ".
2403 Use a more compact way to store MARC-8 conversion tables.
2405 --- 2.0.16 2004/03/16 Debian only
2407 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2410 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2415 --- 2.0.15 2004/03/01
2417 Another fix for decoding of XML packed records.
2419 --- 2.0.14 2004/02/25
2421 Fixes for Chunked encoding. White space not ignored after length spec.
2423 Update NS and use default NS for SRW diagnostic elements.
2425 --- 2.0.13 2004/02/23
2427 Implement ZOOM_resultset_cache_reset which resets record cache.
2429 Implement ZOOM_resultset_sort which sorts a result set.
2431 Implement chunked HTTP transfer.
2433 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2435 --- 2.0.12 2004/02/16
2437 Added member 'schema' to bend_explain_rr structure so that backend
2438 can specify explain record identifier. Defaults to Zeerex 2.0.
2440 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2442 --- 2.0.11 2004/02/16
2444 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2447 Added init command for yaz-client which sends "extra" init request.
2449 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2450 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2452 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2454 Make ZOOM error code for "invalid query".
2456 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2458 --- 2.0.10 2004/02/05
2460 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2463 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2465 Added option -p <file> to make Generic Frontend Server to write PID file.
2467 Added option -D to put Generic Frontend Server in background on its own.
2469 Make ZOOM C recognize option "password". If unset, "pass" is used
2470 (for backwards compatibility).
2472 Fixed a bug in Generic Frontend Server that could make it crash if a
2473 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2476 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2477 Must be issued before open, in order to be in effect.
2479 --- 2.0.9-6 2004/01/12 Debian/Windows
2481 Make the SRU server more picky WRT unknown params, etc.
2483 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2485 New YAZ client command, options, that sets Z39.50 options.
2487 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2488 options from a string of tokens (one token for each option bit).
2490 Update SRW diagnostic code messages.
2492 --- 2.0.9-5 2004/01/07 Debian/Windows
2494 Handle user defined stylesheet for SRW/SRU.
2496 --- 2.0.9-4 2004/01/06 Debian/Windows
2498 Fix bug in decoding of Content-Length.
2500 --- 2.0.9-3 2004/01/06 Debian/Windows
2502 Fix a bug with decoding of XML packed records.
2504 --- 2.0.9-2 2004/01/05 Debian only
2506 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2508 Fix bug in SRW/SRU diagnostics decoding.
2510 --- 2.0.9 2004/01/05
2512 Fixed bug in Generic Frontend Server which could drop records exceeding
2513 preferred message size. Reported and fixed by Irina Dijour.
2515 Fixed calculation of package size for structured records in Generic
2516 Frontend Server. Reported and fixed by Irina Dijour.
2518 Fixed namespace for SRW/SRU diagnostics.
2520 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2522 --- 2.0.8 2003/12/22
2524 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2525 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2528 CQL changes to reflect recent changes to the specification:
2529 * Documentation talks about context sets instead of index sets.
2530 * Documentation talks about indexes instead of qualifiers.
2531 * The CQL-to-PQF transformer's configuration file now uses
2532 "index.set.name = <attributes>" instead of the old form
2533 "qualifier.set.name = <attributes>". (Both forms are still
2534 understood but the latter is deprecated.)
2535 * CQL terms with no explicit index specified are now interpreted as
2536 cql.serverChoice instead of srw.serverChoice (which of course
2537 behaves exactly the same.)
2539 --- 2.0.7 2003/12/16
2541 MARC conversion can now generate ISO2709 output in another
2542 character set. yaz-marcdump uses this facility if you invoke it
2545 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2546 functions from there can be used from C++.
2548 --- 2.0.6 2003/12/04
2550 Frontend server now transfers memory from decoded packages to stream
2553 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2554 references to show up.
2556 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2557 the ZOOM Abstract API. The older names for the same options are still
2558 also supported for the benefit of old applications.
2560 ZOOM-C supports "implementationId" and "implementationVersion" options
2561 to go along with "implementationName". These allow the user code to
2562 specify identification strings to be sent to servers.
2563 Add OID for the new ExtLite attribute set.
2565 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2566 as requested/supplid by Ere Maijala <ere@atp.fi>
2568 For generic frontend server, reverse the order of
2569 "toolkit-supplied / application-supplied" strings sent as implementationId,
2570 Name and Version. Also, remove the spaces around the slash. This brings
2571 the GFS in line with the behaviour of ZOOM-C on the client side.
2573 Add function ZOOM_scanset_display_term.
2575 yaz-client shows scan displayTerm if present.
2577 Utility yaz-iconv is now installed by default along with the man page
2580 Extend configure check for OpenSSL to use pkg-config where available (such
2583 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2584 server to specify uid/gid/mask for socket using the format
2585 unix:[user=uid,][group=gid,][umask=mask,]file=path
2586 If file= is omitted the existing format is assumed, e.g.
2588 in which case the mask is 0666 (rw for everybody).
2590 Major restructure of YAZ source. All source in libyaz is in src directory.
2591 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2592 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2594 Added man page for utility yaz-marcdump (used to be called marcdump).
2595 yaz-marcdump is installed by 'make install'.
2597 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2598 of incoming package failed.
2600 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2602 Change prototype of odr_perror: add const to message string.
2604 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2606 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2607 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2608 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2609 DNS lookup. There should not be any compatibility problems with this
2610 assuming that blocking=1 or 0 is used.
2612 Fix bad reference in UNIX comstack in function cs_addrstr.
2614 Fix for compilation on AIX.
2616 The generic front-end server (server/seshigh.c) now supports returning
2617 Init diagnostics to the client in User-information-field, in
2618 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2621 --- 2.0.4 2003/09/04
2623 Allow any CQL relation (not just all,any,exact,scr).
2625 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2626 that features the same UI.
2628 Implemented command update0 in YAZ client which is equivalent to
2629 update but uses old of Ext Update ASN.1.
2631 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2632 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2633 Previously no OID was used for this info.
2635 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2636 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2637 returns 'malformed search term' otherwise.
2639 SortResponse member resultCount now set to NULL in sort handler of
2642 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2645 Add three new utility functions for translating OIDs between various
2646 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2647 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2648 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2649 char *oid_to_dotstring(const int *oid, char *oidbuf);
2650 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2652 Reverted modifications for ES Update definition for z_IU0Update
2653 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2654 is back to YAZ 2.0.2.
2656 String value attributes for CCL parser.
2658 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2659 which their FirstSearch server returns in Init responses, sometimes
2660 carrying useful diagnostic information when Init fails. This has the
2661 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2662 "z39.50/oclcui.asn", where its definition is somewhat different from
2663 what OCLC document on their web-site, as required to interoperate with
2666 Support for anonymous authentication in yaz-client. Use the command
2669 * Fix the OID of the Index Data-local "admin" Extended Service from
2670 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2671 the 1000, which indicates a locally-defined OID, was a mistake.
2673 --- 2.0.3 2003/06/20
2675 Fix CCL directive @case handling so that it affects string match for
2676 both CCL keywords and qualifiers.
2678 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2679 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2680 Decoder has been updated with ASN.1 changes as listed in
2681 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2682 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2683 z_IUUpdate, remains unchanged.
2685 ZOOM_record_get may now return a record in a specific character set.
2686 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2687 "from" is the character set of record as returned by target. "to" is
2688 the character set to be returned. If omitted, "to" is UTF-8.
2690 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2692 New ODR utility, odr_getelement, which returns name of element for
2693 which encoding/decoding failed.
2695 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2696 in cases where a required element was omitted.
2698 Bug fix: some MARC8 sequences were not converted.
2700 New ZOOM option "step" which specifies number of records to be
2701 retrieved in one chunk. Used in conjunction with "start" and "count".
2703 SRW support for yaz-client. Use scheme http: to use it, e.g.
2706 yaz-client no longer does (un)intelligent character set conversions
2707 by default. Can be enabled with charset and marc_charset commands.
2709 xmalloc trace fix for 64-bit systems such as DEC alpha.
2711 Solaris 2.6 compile fix.
2713 New function, cql_strerror() translates SRW error codes, as returned
2714 by cql_transform_error(), into human-readable English strings. Used
2715 in yaz-client diagnostics when appropriate.
2717 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2718 converts it into a type-1 query which is sent to the server. This
2719 makes CQL available for use with all Z-servers, as opposed to the tiny
2720 minority that can handle CQL queries themselves.
2722 --- 2.0.2 2003/04/28
2724 New Debian package layout similar to the Redhat Package layout.
2726 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2727 and search result respectively.
2729 --- 2.0.1 2003/04/25
2731 Redhat package is now several packages: libyaz (runtime libraries),
2732 libyaz-devel (development and documentation, and yaz (utility programs).
2733 Package spec file by Morten Bogeskov.
2735 New member 'schema' in struct bend_fetch_rr which the name of requested
2736 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2737 handler MAY set this to reflect the schema of the returned record.
2739 New member 'display_term' in struct scan_entry. GFS now sets member entries
2740 and allocates scan entries to be filled by user scan handler. In previous
2741 version, entries member was allocated by the scan handler. That still works,
2742 but the GFS will ignore member display_term - assuming it was NOT set by
2743 the handler. The fact that the GFS now allocates the entries both allows
2744 for new members and makes a scan handler easier to write.
2746 Fix CQL lex buffer overflow.
2748 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2749 SRU default recordPacking is string.
2751 SRU protocol support for frontend server.
2753 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2755 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2757 Added scan for the ZOOM shell (zoomsh).
2761 * String Identifers for Schemas (Amendment 5).
2762 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2763 Old definition for schema
2764 Odr_oid *schema; /* OPT */
2769 Z_InternationalString *uri;
2770 #define Z_Schema_oid 1
2771 #define Z_Schema_uri 2
2774 * resultCount parameter to Sort Response (Amendment 1).
2775 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2777 Support for SRW 1.0 over HTTP. This is an optional feature and
2778 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2781 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2782 on the same port. SRW SearchRetrieveRequests are mapped
2783 to bend_init,bend_search,bend_fetch,bend_close.
2785 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2787 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2788 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2790 ZOOM connections are SRW based if schem http is used for hostname
2791 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2792 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2794 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2795 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2796 distance=n, order=true/false, relation=le, prox unit=word. If
2797 n is omitted, distance 1 is used.
2799 Fixed problem with C compiler include path in wrong order.
2801 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2802 on Solaris. Patch from Ko van der Sloot.
2804 New MARC decode API. All new functions operate on a yaz_marc_t
2805 handle. The most important new functions are: yaz_marc_create,
2806 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2807 decode and destroy respectively. Decoder can produce formats
2808 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2809 include/yaz/marcdisp.h.
2811 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2812 to UTF-8, UCS-32, wchar_t or Latin-1.
2814 * Prototypes for yaz_iconv_-functions moved to separate header
2815 include/yaz/yaz-iconv.h.
2817 Make a few private functions 'static' in unix.c. This prevents
2818 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2820 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2821 are set when Init Response is received.
2823 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2824 but returns diagnostic set as well.
2826 New function yaz_strerror which is a portable wrapper for
2827 strerror/strerror_r/GetLastMessage.
2829 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2830 is returned for MARC. If type is "oai", then OAI MARC is returned.
2832 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2835 --- 1.9.2 2002/11/26
2837 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2839 Fix bad race conditions on SIGTERM and terminate gracefully in
2842 Move retrieval (data1) module to Zebra since nobody seems to be
2845 Add GRS-1 render for ZOOM using same format as yaz-client.
2847 --- 1.9.1 2002/10/05
2849 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2851 Fix broken ESpec handling in data1 module.
2853 SGML reader parses comments and makes them part of the data1 tree.
2855 Added several type casts so that YAZ compiles as C++ code.
2857 ZOOM didn't handle PDU encoding failures properly.
2859 Added more Bib-1 diagnostics (approved extensions).
2861 GNU configure: better check for iconv.
2863 More portable use of accept, getpeername. Check for socklen_t. Use
2864 int/size_t if socklen_t is not defined.
2868 PQF parser rejects bad queries - including those with extra
2869 characters in them. PQF parser used to silently ignore that.
2870 Cleaner API for PQF added, which allows you to get detailed
2871 error information for bad queries (see yaz/pquery.h).
2873 Fixed bug in ZOOM_record_get for type "database".
2875 Implemented mini iconv library supporting conversions between
2876 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2878 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2880 --- 1.8.9 2002/08/20
2882 Fixed ZOOM C record cache so that preferredRecordSyntax and
2883 elementSetName is used to check for already fetched records.
2885 --- 1.8.8 2002/08/02
2887 Added three members in bend_initrequest structure to facilitate
2888 character set negotiation.
2890 Fixed a bug in frontend server that could cause indefinite
2891 loops under rare conditions.
2893 Revised character set utilities (charneg.h) so that encoding
2894 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2896 For PQF, directive @term <type> sets term type for Scan/Search.
2897 Here <type> is general, string, numeric, null. The term type
2898 is inherited - just like @attr.
2900 New call odr_set_charset that sets character set conversion for
2901 international-strings on a ODR stream. Prototype is:
2902 int odr_set_charset(ODR o, const char *to, const char *from);
2903 The InternationalString is still represented as C string in YAZ
2904 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2905 won't). On the protocol level, you can use any encoding.
2907 Support for UNIX sockets in ZOOM.
2909 Solaris recv sometimes returns errno == ENOENT. It is treated as
2910 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2912 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2913 both client and server. Code by Morten Bogeskov.
2915 --- 1.8.7 2002/05/22
2917 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2918 that they can be used directly from Visual Basic. You must recompile
2919 your windows APP if you're using ZOOM.
2921 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2922 Commands "lang" and "charset" sets language and character set respectively.
2923 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2924 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2926 Attributes from multiple CCL fields may be OR'ed rather than merged
2927 using directive "@field or". Fields are still merged by default -
2928 equivalent to "@field merge".
2930 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2933 Fixed bug in zget for parameter ExtendedServicesResponse.
2937 --- 1.8.6 2002/03/25
2939 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2941 Client displays USR.1:SearchResult-1 (hits per term).
2943 Additional Search Info for search in Generic Frontend Server.
2945 Fixed CCL parsing of "field=s".
2947 WIN32 installer - using the excellent NSIS software from nullsoft.
2949 Fixed CCL parsing of "field = - <number>".
2951 Added function yaz_marc_decode that decodes MARC for line mode
2952 display or XML (similar to that used by JZKit).
2954 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2955 Z39.50. But ISO/ILL was, however.
2957 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2958 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2960 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2961 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2963 --- 1.8.5 2002/02/03
2965 New YAZ client features: Command completion and new commands:
2966 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2967 Code provided by Jacob Poulsen.
2969 New call oid_trav, that visits all registered OIDs via callback.
2971 Function ZOOM_record_get now returns const char pointer rather than
2972 void pointer. It saves a lot of type casts.
2974 For YAZ client, command "auth" now allows you to set authentication
2975 in IdPass style. It is enabled when three tokens are given - order
2976 is user, group and password.
2978 Fix memory leaks in MARC record handling for ZOOM.
2980 New option for YAZ client, -k <kilobytes> that sets
2981 maximum record size. Similar to -k option for generic frontend
2982 server and yaz-ztest.
2984 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2986 Prefix query parser reports "fail" when bad attribute set is given.
2988 Fix in MARC decoder. Proximity logging. Fix for attribute set
2989 in scan handler for server. Patches by Shigeru Ishida.
2991 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2994 Configure option --with-openssl=<dir> now works when a directory is
2995 specified. Patch provided by Morten Bogeskov.
2997 New option for YAZ client, -u <auth>, that sets authentication.
2999 ZOOM fix: error information was sometimes "missing", since error
3000 was cleared/reset too when it shouldn't.
3002 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3004 --- 1.8.4 2002/01/04
3006 Scan for ZOOM API. New object ZOOM_scanset. New functions
3007 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3008 ZOOM_scanset_destroy.
3010 New ZOOM function, ZOOM_connection_last_event, that returns type
3011 of last event (such as "receive data", "send data", "apdu received",
3014 New ZOOM option, schema, that specifies schema for retrieval.
3016 New CCL feature. Qualifiers can be aliases for one or more
3017 other qualifiers (if more than one is given, OR is used).
3019 ZOOM uses named result sets if target supports it.
3021 Two new YAZ client commands: . (dot, which sources a script of YAZ
3022 client commands), and ! (to execute shell command.). Implemented
3025 Working on Debian packages.
3027 --- 1.8.3 2001/11/19
3029 YAZ client enables named result sets only if target supports it.
3031 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3033 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3034 with key="host" to get same result.
3036 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3037 Function Z3950_resultset_record(s) returns references to records
3038 "owned" by resultset. To become owner use Z3950_record_clone.
3040 Function z_ext_record handles Extended Services. Thanks to
3043 --- 1.8.2 2001/11/12
3045 CCL Parser fix: ignore token comma when dealing with and-lists.
3047 Documentation updates for COMSTACK.
3049 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3050 Changed prototype Z3950_records. For some functions, int parameters
3051 were changed to size_t.
3053 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3056 New MARC decode/display function, marc_display_exl, which properly rejects
3057 non-ISO2709 records. YAZ client uses it.
3059 --- 1.8.1 2001/10/29
3061 Fix bug: local attribute set wasn't set correctly in PQF strings.
3065 * Old Z39.50 codecs no longer supported.
3067 Added ZOOM C binding. See http://zoom.z3950.org/
3069 Renamed states for COMSTACKs to avoid confusion with events.
3071 Implemented cs_look and proper cs_rcvconnect.
3073 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3075 Configure detects POSIX threads on OpenBSD.
3077 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3078 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3080 When error is returned from present handler, non-surrogate diagnostic
3081 is returned in present response (and fetch handler is no longer called).
3083 * Minor adjustments to pquery parser (PQF). Token characters may be
3084 escaped by using backslash (C-style).
3086 PQF parser allows string attribute values to be specified. For @attr,
3087 non-numeric characters after the equal-sign are treated as strings
3088 (e.g. @attr 9=title).
3090 CCL trunction character may be defined (@truncation in file)
3092 * function zget_ExtendedServicesRequest sets waitAction to
3093 waitIfPossible (was wait).
3095 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3098 CCL operator names may be set in field definition files (CCL_bibset).
3099 See ccl/bib1 for an example.
3101 Fixes in ASN.1 compiler for C++ compatibility.
3103 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3104 and "op_or" to avoid conflict with C++.
3106 Fixed problem with GNU readline detection on Redhat 7.0.
3108 Added step-size for Scan backend handler.
3110 Fixed bug that made the frontend server crash when no attribute
3111 set was specified for scan.
3113 Front-end server automatically switches to original working directory
3114 when installed as an NT service. Previously -w had to be specified to
3117 Added extended attributes for retrieval module (data1), so that data1
3118 records carry d1_readXML/SGML attributes. d1_read also supports
3119 null-data rules ( <tag/>)
3121 On UNIX when POSIX threads are available, a separate library libyazthread
3122 is created. Programmers should link with that library and the yaz library
3123 when using threads. The reason for the split was that some applications
3124 on Linux, such as Apache, doesn't work well when using shared objects that
3127 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3128 (or any frontend server) in SSL mode by specifying ssl: followed by
3129 address. Only tested on UNIX.
3131 Added feature for CCL module. Virtual structure s=al or s=ol generates
3132 and-list and or-list respectively instead of phrase search.
3136 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3137 log_mask_str. This was done to avoid name conflicts with other libraries
3138 (such as other PHP extensions).
3140 Added raw OID member for preferred record syntax (request_format_raw)
3141 and returned record syntax (output_format_raw) for backend fetch method.
3143 Config file yaz-config now accepts options so that it returns specific
3144 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3146 Shared library support for UNIX using GNU libtool.
3148 * Modified backend interface. Request/Response struct's replaced by
3149 one read/write C struct. For example bend_fetchrequest and
3150 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3151 Every handler - even search has to be registered in bend_init
3152 handler. This means that the YAZ library no longer refers to
3153 external functions and it makes it possible to make the whole
3154 thing a single DLL/SO.
3156 Added Segment handler for backend server.
3158 Added Zmbol/Zebra administrative functions to YAZ client.
3160 Threaded frontend server on UNIX (when POSIX Threads are available).
3161 Starting the server with option -T enables multi-threading.
3165 Added configure option --enable-comp/disable-comp to control use
3166 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3167 located in sub directory asn.
3169 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3170 in ${exec_prefix}/bin along with the other programs yaz-client and
3173 GNU automake used to maintain makefiles.
3175 Added several OID's.
3177 Changed retrieval module so that we can load records with no abstract
3178 syntax defined. Tagpaths in these records are fully composed of string
3181 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3185 On UNIX, the generated makefile now supports a proper 'make install'.
3186 The prefix can be set via GNU configure to set the install location
3187 (default is /usr/local).
3189 * YAZ programs client and ztest were renamed to yaz-client and
3190 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3191 locations, such as /usr/bin,/usr/local/bin,etc.
3193 * YAZ Header files were moved from include to include/yaz. YAZ Header
3194 files are referred to as include <yaz/log.h> rather than <log.h>.
3195 The YAZ include path (-I ..) is therefore the same as before. Programmers
3196 should update their #include statements or use -Ipath/include/yaz
3197 instead. The main motivation for doing this change is that YAZ header files
3198 can be installed in "standard" locations /usr/include,/usr/local/include
3199 without introducing conflicts, since ALL YAZ header files are stored
3200 in subdirectory yaz (under /usr/include for example).
3202 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3203 rather than project/workspace files. We switched because project files
3204 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3207 Changed name of logging function, logf, to yaz_log, to prevent name
3208 clash with some math-log functions. The YAZ header log.h defines logf
3209 to yaz_log (#define) so there should be no incompatibilities by this
3212 Added bend_start/bend_stop handlers for server. These handler are
3213 called on start/stop of server. For windows they are called whenever
3214 a service is started/stopped.
3216 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3217 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3218 in util/yc.tcl. The auto-generated C code structures are, in a few
3219 cases, incompatible with the old decoders. There are differences in the
3220 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3221 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3222 The preprocessor variable ASN_COMPILED is defined when the compiled
3223 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3224 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3225 wish to use the old encoders/decoders you can specify --disable-yc
3228 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3229 version so that it supports both new - and old version of DB Update
3231 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3232 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3233 change. The name parameter can be set to 0 in which no name is specified
3234 for the construction. The macros odr_implicit and odr_explicit sets name
3235 parameter to zero for the construction involved. New macros
3236 odr_implicit_tag and odr_explicit_tag are similar to the others,
3237 except that a name parameter is added. For programmers' that don't use
3238 ODR they probably only need to change the call to z_APDU and z_External.
3240 Added access control facility by interfacing the TCP wrapper library.
3241 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3242 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3243 name of the daemon and enables the access control as specified in
3244 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3246 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3247 den Dool <H.M.vdnDool@kub.nl>.
3249 Added reference ID parameter to most functions in server API - refer
3250 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3252 Changed name of ccl library to libccl.a (was ccl.a).
3254 Fixed bug in decoder for Explain (Category TargetInfo).
3256 Added support for GNU readline in client. Thanks to Jacob Poulsen
3257 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3259 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3260 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3261 IMPLEMENTATION! This change was made to the development version before
3262 the ZIG decided to retract the amendment. If any users MUST be
3263 compatible with the original Update definition, PLEASE CONTACT US, and
3264 we will include a separate definition corresponding to the old Update
3265 ES. Note that because of the change to the ASN.1 of the
3266 TaskPackageRecordStructure we cannot define a single structure that
3267 will support both versions.
3269 * Added const modifier to buffer parameter for some ODR/BER encoding
3270 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3271 completeWAIS, odr_dumpBER.
3273 Fixed bug in client.c which caused a crash when a scanResponse didn't
3274 contain positionOfTerm.
3276 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3277 * will cause an error in a client if a non-YAZ target sends both a
3278 * list of Scan entries and non-surrogate diagnostics.
3280 Retrieval module enhancements. Tag sets may be typed in the reference
3281 to it. From the .abs-file the "tagset" directive takes a third optional
3282 integer type for the tag set referenced. From a .tag-file the "include"
3283 directive takes a third optional type as well. The old "type" directive
3284 in the tag set itself is still recognized but acts as the default type
3287 Backend interface change. Individual Scan terms returned from bend_scan
3288 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3289 in include/backend.h.
3291 Retrieval module enhancements. Multiple tag sets and attribute sets may
3292 be specified in abstract syntax specs. Revised the error/warning for
3293 logging messages reported by the retrieval module when reading the
3296 Object Identifier system (oid_..) changed. The API is backwards
3297 compatible but the oid-routines now allocates new OID's when needed.
3298 Raw OID's may be specified in oid_getvalbyname.
3300 YAZ now uses GNU configure to generate Makefile(s).
3302 * Minor changes in some of the member names of DeleteResultSetRequest and
3303 DeleteResultSetResponse. See include/proto.h.
3305 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3306 and added member 'languages' in TargetInfo (which was missing).
3308 Changed the way attribute sets are handled in the retrieval
3309 module. These are now cached, just like the abstract syntaxes
3312 Changed YAZ so that it links with compiled ASN.1.
3314 Added Explain-schema definitions and mapping routines. The following
3315 Explain categories have been implemented: AttributeDetails,
3316 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3318 Fixed minor bug in Windows version of Server Library.
3320 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3322 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3324 Added EXTERNAL: UNIverse Resource Report (non-standard).
3326 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3327 ENUMERATED and SET OF.
3329 * Added 'const' to some of the char pointer arguments for the
3330 functions, data1_read_node, data1_getelementbytagname,
3331 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3334 Fixed bug in data1_insert_taggeddata - the last_child member of
3335 parent wasn't initialised.
3337 * Changed data1_read_record and data1_read_node so that the supplied
3338 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3339 doesn't refer to any parts of the "SGML"-buffer.
3341 Fixed bug in server library (Windows version of statserv_remove).
3343 * Changed code so that it compiles as C++. The type definition
3344 of Odr_fun which is a member of Odr_arm was changed. The result is,
3345 that an explicit typecast is needed for the fun pointer when
3346 using Odr_arm - as in:
3347 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3349 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3351 Implemented the new structured date and time definition as approved
3352 by the ZIG. Added schemaId element to the specificTag in Espec-1
3353 (also approved at the last ZIG). Thanks to RVDM.
3355 Added some Object identifiers (RVDM).
3357 Changed the Update Extended Service (RVDM).
3359 Added command "refid" to client which specifies referenceId for
3360 the following requests.
3362 Implemented extended service handling for server. See ztest.c
3363 for an example as well as backend.h. New handlers are registerd
3364 in the Init handler.
3366 * Changed interface for sort in server.
3368 Added new members to statserv_options_block. It allows a server
3369 to read options from another source than just the command line. Thanks
3370 to Charles Woodfield.
3372 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3373 renamed to zboolean. Some C++ compilers complained about the name.
3375 Minor changes to gils.abs. Added index 's' (sort) on title
3376 and date/time-last-modified.
3378 --- 1.4pl2 1998/1/30
3380 Fixed bug in server library regarding inetd mode (-i). This bug
3381 was introduced by release 1.4.
3383 --- 1.4pl1 1998/1/29
3385 Added sort facility in client and backend server interface.
3387 Fixed problem with dependencies in Makefile(s).
3389 Fixed bugs for encoders/decoders of extended services and
3392 Implemented sub-tree feature for schemas. Sub-trees are
3393 referenced in *.abs-files. See explain.abs for an example
3394 of the use of this feature.
3396 Modified bib1.att; local attributes for ANY didn't include
3397 ANY itself (only affects use of the retrieval module).
3399 Fixed bug in plain SGML reader in function data1_read_node:
3400 tags with prefix "var" was incorrectly interpreted as variants.
3402 Added feature "sub-schemas" to enable references to - and definitions
3403 of - group of elements.
3405 * Removed member parent from type data1_element (in data1.h).
3407 Implemented function odr_nullval() that returns the value of
3410 * Removed member num_children from data1_node (in data1.h).
3412 Made NT service interface part of the server library. The
3413 function statserv_main uses the NT service when required and
3414 calls the statserv_start / statserv_close routines.
3416 Routine zget_SearchRequest and zget_PresentRequest fills
3417 resultSetName/Id member with "default" instead of "Default".
3419 Fixed memory leak in server. Request queue member wasn't freed.
3421 Fixed nmem_exit so that memory is freed.
3425 Revised the CCL parser utility to be thread safe.
3427 Added function, oid_ent_to_oid, to replace the function
3428 oid_getoidbyent, which is not thread safe.
3430 * Added nmem_init and nmem_exit to initialize and release
3431 NMEM resources. Function nmem_init should be called once in the
3432 initial thread before NMEM/ODR is used. statserv.c and client.c
3433 have been changed accordingly. The change was necessary to make
3434 NMEM thread safe. The NMEM memory pool is shared amongst threads
3435 in a process. Unix-based applications will still work fine without
3438 Added NT Services interface for the the Z39.50 (statserv) Server.
3439 Refer to the ztest.c source on the usage.
3441 Windows 95/NT port using MSVC5.0. Project files are included in the
3444 * Defined new 'global' handle for the retrieval (data1) system. The
3445 new handled, data1_handle, describes the state of the data1 system.
3446 This handle is passed as first argument to virtually all
3447 data1 related routines. The functions data1_create and data1_destroy
3448 creates and destroys a data1 handle respectively.
3450 Added ODR encode stream member to all backend request structures
3451 init, search, scan etc. This stream should be used to allocate all
3452 memory used for the response when thread safe operation is needed.
3454 Changed the comstack utility, cs_addstr, to be thread safe. The
3455 returned hostname string returned by the function is now part the
3458 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3459 function. The cs_straddr takes a COMSTACK handle as argument, so this
3460 function must be used after cs_create and before bind/connect.
3461 This function is thread safe.
3463 Moved test server to 'ztest' directory - generic server code still
3464 in 'server' directory.
3466 Made prefix query (pquery.c) utility thread safe.
3468 Added new function modifier YAZ_EXPORT to 'export' public DLL
3469 functions when using windows (see include/yconfig.h).
3471 Added definitions to the OID database (util/oid.c) (RVDM).
3473 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3475 Added call to ccl_rpn_delete in client program.
3477 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3478 release of RPN structure.
3480 Added support for C++, headers uses extern "C" for public definitions.
3481 With input from RVDM.
3483 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3484 Thanks to Ronald van der Meer (RVDM).
3486 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3488 Added support for private extensions to the OID database
3489 (oid_setprivateoids()). Thanks to RVDM.
3491 Added optional, physical ANY (key replication)
3493 Fixed null-reference problem in GRS-1 output filter.
3495 Proximity operator added to Prefix Query Format (PQF).
3497 In test client command "base" accepts multiple databases.
3499 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3503 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3505 Smallish bug-fixes in the new encoders/decoders (explain).
3507 Bug fixed in DeleteRequest.
3509 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3511 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3513 Added SOIF syntax (using private OID for now) to retrieval module and client.
3515 Added Update extended service.
3517 Added SearchResult-1 additional info structure.
3519 Added optional CCL (ISO8777) interpreter as separate module. Available
3522 --- 1.2 1996/6/10 (1st anniversary release)
3524 Added Summary record syntax. Lightly tested.
3526 Added OPAC record syntax. Untested.
3528 Added ResourceReport service encoders/decoders. Untested.
3530 Fixed bug in z_Unit - wrong tagging on unitSystem.
3532 Fixed bug in the DiagRecs decoder.
3534 Added options for max PDU size and session timeout to frontend-server.
3536 Added documentation of query-language parsers and other supporting utilities.
3538 [frontend-server] Added Attribute set to the bend_scanrequest API.
3540 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3541 surrogate diagnostics were generated.
3543 [retrieval] Allow multiple local values for attribute.
3545 [retrieval] Allow multiple attributes per element in .abs files. index type.
3547 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3549 --- 1.1pl2 1996/4/10
3551 Minor changes, mostly specific to Zebra's requirements (retrieval)
3555 Repaired bug in frontend server when running multiple listening
3556 endpoints in dynamic mode.
3558 z_External() now won't break if a known, ASN.1 value comes encapsulated
3559 in an octet-string. The value will pass through unmodified in an Odr_oct.
3561 Added a bit of code to the demo client to decode & display
3562 ASN.1-structured records represented in the octet-aligned branch of
3563 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3565 Added z_ext_getentbyref() to the ASN module. Doc updated.
3567 * Completed the SCAN definition in the ASN module. This may break SCAN
3568 code based on older YAZ-versions at compile-time. The fix is easy -
3571 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3572 under the SCAN definition. Remember to initialize this, server-people.
3574 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3575 that this does not extend to ODR and ASN.
3577 Comstack allows insertion of established socket (primarily for
3578 inetd-operation of servers). Doc updated.
3580 Front-end server can now start from the inetd in TCP mode. Doc
3583 --- 1.0pl4 1996/1/24
3587 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3588 the rank and record number.
3590 Adjustments to the frontend server.
3592 Fixed diagnostic BER dumper. It ignored the file argument.
3596 Various changes to retrieval module.
3598 Changed the union discriminators of the protocol files from enums to
3599 ints paired with #defines.
3601 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3604 *Changed operator in the RPN structure to 'roperator', again to avoid a
3607 Fixed problems in Explain decoders/encoders.
3609 --- 1.0pl2 1995/12/6
3611 Memory bug in log module fixed.
3613 --- 1.0pl1 1995/12/5
3615 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3617 Bug in Explain DatabaseInfo module fixed.
3619 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3623 The shift to v1.0 signals that we now consider the *core* functionality
3624 of YAZ reasonably stable (the core being more or less equivalent to
3625 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3626 tested (Explain not at all - though that will happen soonish).
3628 Minor changes to code to support Windows port.
3630 Various minor changes after we're getting to use GRS-1 & co. more.
3632 Added Espec-1 format.
3634 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3635 of the protocol and it cannot be selected when encoding (maps into 'string'
3636 when decoding). Needed to talk to some servers.
3638 Demo client can request simple element set names.
3640 Added Diagnostic Format encoders/decoders.
3642 Added simple Close handling to frontend server (no hooks for resource
3643 reporting yet), and demonstration client.
3645 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3647 --- 1.0b3 1995/08/24
3649 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3650 handled incorrectly when records were requested in the searchResponse. This
3651 will only affect you if you use the frontend-server.
3653 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3654 Test-client will ask for and print GRS1. Ztest will return dummy records
3657 Added Explain encoders/decoders to the service-level API. Untested.
3659 Added Extended Services: Item Order encoders and decoders to the Service-
3660 level API. Untested. We could use a recent copy of the pertinent bits
3661 of the ILL protocol to add those bits.
3663 Added diagnostic format 1 encoders/decoders to the service-level API.
3666 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3667 odr_cons.c, which causes a more correct output.
3669 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3670 was always set to 0 when no records were requested in the searchRequest.
3672 * Added better external-handling. This shouldn't harm old code that
3673 *encodes* externals. It can break code that looks for a
3674 'single-ASN1-type' representation, since those types that are known
3675 are now decoded immediately. Look at the SUTRS sample code in
3676 seshigh.c and client.c. Documentation updated.
3678 Handling of structured records in bend_fetchresponse. Length -1 marks
3679 structured record, type is deduced from format field.
3681 --- 1.0b2 1995/06/27
3682 Fairly quick maintenance release to add SUTRS support.
3684 Fixed handling of SUTRS records in the demonstration client.
3686 * Added format field to the bend_fetchrequest and bend_fetchresponce
3687 structures of the backend API (frontend server). When the record is
3688 returned, the value of the format field is mapped to an OID. The
3689 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3690 of the record. The special value VAL_NONE in the bend_request means
3691 that no specific format was requested by the client. Documentation
3692 updated accordingly. Test server (ztest) will return a fixed dummy
3693 SUTRS record if your client requests SUTRS.
3695 Documentation updated accordingly.
3697 You can now set external libraries and RANLIB support in the top-level
3701 First public release.
