1 New ZOOM C feature: result-set caching. For this to work, YAZ uses
2 libmemcached to interface with memcached. Quick way to get started:
4 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
8 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
10 SRU GET/Solr base URLs may hold additional ?args YAZ-729
11 ZOOM option extraArgs already does this, though. It seems useful
12 when dealing with Solr targets to limit by filter, eg.
13 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
15 Remove #fragment for HTTP request encoding YAZ-730
17 Doc: Update list of DLLs/LIBs
19 Doc: update href link to Unix utils and Git.
23 ZOOM: fix "lost connection" problem with servers that uses both squid
24 and another proxy behind it that returns Location headers with relative
27 zoomsh: do not use readline for stdin (no tty) YAZ-724
28 Just use fgets in that case. If the user hits Ctrl-D a new-line
31 zoomsh: empty command ignored YAZ-723
32 rather than performing exit of zoomsh.
34 yaz-url utility offers option -v to enable verbose mode.
36 yaz_url uses yaz_check_location and offers verbose mode.
38 Add new function yaz_check_location.
39 This function gets an absolute URI from Location (HTTP redirect).
41 cookie API: introduce yaz_cookies_reset
43 Update cql.y for newer bison YAZ-720
44 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
45 longer supported. Instead one must use %lex-param and %parse-param .
49 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
52 rpn2solr: support truncation left(2), left&right(3) YAZ-718
54 Mention SRU version 2.0 in yaz-client man page.
58 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
63 Make cs_parse_host public.A
65 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
66 introduced in YAZ 5.0.6.
70 Fix buffer corruption for yaz-ztest record fetch.
74 Allow yaz-ztest to return user-defined records (one record per file).
75 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
77 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
78 Use the stream write instead of odr_printf which has a 4K tmp buffer.
80 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
84 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
85 can read and write this format. For record format JSON, yaz-ztest returns
88 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
89 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
93 Improve error reporting for ICU chains YAZ-707
94 Report config element+rule when ICU status is "failure".
96 ZOOM: stop fetching if present response has no records YAZ-710
97 Some targets return less records than their hit count would suggest.
98 This prevents ZOOM from continuing to fetch records if any present
99 response has 0 records in the response.
101 Ensure that GFS calls exit if any listener fails YAZ-710
102 Before, if XML config was in use, it would start the default
107 yaz-ztest: -V shows version (like yaz-client -V)
109 New iconv encoding: danmarc YAZ-692
111 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
113 daemon: only wait for immediate child rather than all children. YAZ-704
115 yaz-client: fix setting of SRU record schema. If scheme was unset, it
116 could lead to invalid memory reference.
120 yaz-ztest returns schema for MARCXML test records. SRU require that
121 recordSchema for records.
123 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
124 instead of non-surrogate diagnostic. This is a per-record failure.
126 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
127 may refer to multiple listeners now. Attribute listenref is a comma separated
130 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
131 option is given for GFS, the dirname of filename (for -f) is used
132 as prefix for options such as cql2rpn, ccl2rpn, etc.
134 Content-Type charset fixes YAZ-701 . Do not inspect charset in
135 Content-Type header for SOAP when decoding SRU. The payload (XML)
136 itself tells what encoding it is. In response, never supply encoding
137 in Content-Type. The response payload (XML) tells what it is (with no
138 encoding in XML it's UTF-8).
140 HTTP decoding: allow blanks in URL paths YAZ-700
144 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
145 and facets. Ensure recordData and recordSchema are always present in
146 record element, because they are required.
148 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
151 Simplify in a lot of places using odr_strdupn.
153 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
157 Increase various buffers in GFS's statserv_options_block
158 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
159 This change makes many type-casts redundant, and, thus simplifies code.
161 Remove last bits of WAIS support.
163 Remove member 'size' from Odr_oct.
165 Slim down the public part of 'struct odr'. Most elements are not part
166 of struct Odr_private.
168 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
169 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
170 In particular facets are supported in both client - and server side.
171 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
172 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
173 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
174 both request/response). This is what a search handler in the GFS
175 will see (regardless of whether operating in SRU mode or Z39.50).
177 Changes to the srw.h (SRU/Solr) definitions include:
178 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
179 (char*), which replace union query and query_type (int). This is because
180 SRU 2.0 supports a queryType parameter. This also means that, to carry
181 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
182 x-pquery=PQFstring (extention parameter). The extension parameter
184 - New element, packing, that has information about SRU
185 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
187 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
189 New element, packing, in Z_SRW_explainRequest.
191 New elements in Z_SRW_scanRequest, queryType and scanClause.
192 These replace query_type and scanClase untion. This is similar to what
195 --- 4.2.69 2013/10/01
197 GFS: log when closing down - at least SIGTERM YAZ-684
198 Also change formatting WRT PID logging a bit.
200 Improve display of MARC records with multi-byte subfield IDs YAZ-695
201 In some rare cases subfield identifiers are multi-byte characters.
202 This will try to deterime length of those and split accordingly.
203 This affects display in line mode as MARCXML/MarcXchange. The encoding
204 of ISO2709 is the same.
206 Change inp argument to const for yaz_read_UTF8_char.
208 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
210 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
212 Better check of marc leader info YAZ-691
213 Problem is that some systems generate MARCXML/MarcXchange with
214 funny headers. These will not work if encoded as ISO2709.
215 Some tests produce new output, due to updated warning messages
217 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
219 yaz-client: display MAB records YAZ-689.
220 Thanks for Heiko Jansen for this patch.
222 New utility z_get_HTTP_Response_server which allows both HTTP server name
223 and HTTP server URL to be given in response.
225 Debian: do not depend on obs tcl8.3.
227 Debian: do not depend on obs libicu36-dev.
229 --- 4.2.68 2013/09/23
231 GFS: pass additionalSearchInfo to search memeber search_input if
232 given. Otherwise pass otherInfo. Request for facets and other search
233 related things will be passed there in future versions of YAZ.
235 New ZOOM setting, authenticationMode, which allows authentication
236 paramters to be encoded in the URL rather than via HTTP Basic auth.
239 rpn2solr: fix nested AND/OR handling. YAZ-685
241 Add comparison routines for some Z-types, such as NamePlusRecord,
242 RPNQuery, Query, RecordComposition and OtherInformation.
244 --- 4.2.67 2013/09/19
246 Don't decode MAB as MARC. Just like we don't attempt to decode
247 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
249 CCL: allow quoted terms for date ranges. YAZ-681
251 Introduce ccl_parser_qual_search. This function makes old function
252 ccl_qual_search, from YAZ 2, available again.
254 Add yaz_facet_list_to_wrbuf. YAZ-683
256 --- 4.2.66 2013/09/11
258 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
259 schema was given for search. YAZ-675
261 Add Solr date range searches. YAZ-621
263 --- 4.2.65 2013/08/22
265 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
267 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
269 ISO2709/MARC parse most octet aligned records; not just those that
270 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
271 MARC parse more records instead of just dumping as is. YAZ-670
273 ZOOM: proper caching for variations of record schema. YAZ-671
275 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
277 --- 4.2.63 2013/07/17
281 --- 4.2.62 2013/07/11
283 New utility z_get_HTTP_Response_details - an extended version of
286 New utility yaz_url_get_error which returns error message of last
287 failed yaz_url_exec call.
289 yaz-url and url functions: allow max HTTP redirects to be controlled.
291 New functions yaz_file_glob2, yaz_xml_include_glob.
292 These functions takes a flags parameter, which, for now only controls
293 whether to fail inclusion of a non-existing file (without glob
294 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
296 --- 4.2.61 2013/06/20
298 For MARC XML parsing, allow record without leader. A fake/default leader
299 is inserted and a warning is tagged with the record.
301 ICU: fix leak in in icu_iter_get_org_info.
303 --- 4.2.60 2013/06/14
305 ICU: fix bug in icu_iter_get_org_info (un-init variable).
307 --- 4.2.59 2013/06/11
309 Implement z_HTTP_header_remove.
311 --- 4.2.58 2013/06/11
313 ICU: Disallow 0 ptrs for some ICU string utilities.
315 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
316 returns original tokens (before normalization).
318 CCL: avoid z39.58/regex truncation when not needed. Apply only the
319 conversion of those masks, when absolutely necessary.
321 CCL: configurable masking character - @mask. Default masking character
324 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
325 full response anyway, so a Transfer-Encoding header will obstruct the
328 --- 4.2.57 2013/05/15
330 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
331 picking a socket. Problem is that some systems has IPV6 support, but
332 we can't create sockets for them, so we pick AF_UNSPEC first.
334 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
335 use content_len to determine resulting Content-Length in HTTP response
336 and NOT Content-Length supplied in headers by user.
338 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
339 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
341 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
344 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
345 with big endian and unsigned char (by default).
347 --- 4.2.56 2013/04/26
349 Fix yaz-client connect (crash in 4.2.55).
351 --- 4.2.55 2013/04/26
353 Fix proxy/host problem for ZOOM that could occur if unix sockets
356 New Debian package libyaz4-dbg.
358 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
359 differently in tcpip_close.
361 --- 4.2.54 2013/04/17
363 Windows installer of YAZ includes YAZ4J as a component.
365 CQL: allow "extra terms" again, by default. Thus, the CQL parser
366 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
367 and earlier. CQL parser may operate in strict mode where queries
368 not conforming to the standard BNF are rejected (syntax error).
369 Whether the CQL parser operates in strict mode is controlled with
370 cql_parser_strict . Strict mode enabled with option -S for utilities
371 cql2pqf and cql2xcql .
373 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
375 --- 4.2.53 2013/04/10
377 New charset, MARC-8c, which is like MARC-8 but allows control characters
378 0x01 through 0x1F, except ESC to be passed through verbatim.
380 Fix a problem with duplicate sub field character in MARC output. Problem
381 happened only when output was MARC-8 encoded.
383 --- 4.2.52 2013/04/03
385 yaz-ztest: Use hash for fake hit count. Before, random number was used.
386 This is problematic for unit tests using yaz-ztest. This patch also makes
387 a hash for CQL queries. For RPN, any term with a leading digit will be
388 treated as pseudu hit count (to force any particular hit count by a client).
390 yaz-ztest: return unique MARC dummy records. Beyond record offset
391 24, the author surname is patched with offset to make all records
394 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
395 on system wide default (/proc/sys/net/ipv6/bindv6only).
396 @4 binds to IPV4 only. @6 binds to IPV6 only.
398 Update CQL API documentation a bit
400 CQL: don't accept extra terms for queries. Makes the CQL parser
401 stricly conformant to the standard.
403 --- 4.2.51 2013/02/12
405 GFS: scan handler gets extra_args from request and may return extra
406 response data . That's for SRU only.
408 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
410 --- 4.2.50 2013/01/30
412 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
414 OPACXML: sync spelling of availabilityDate in XML to that of Schema
415 opaxxml.xsd. The schema had the correct spelling of this member always.
416 The ASN.1 was mis-spelled and still is (API change) - we are
417 not changing this. However, the OPAC to XML conversion had yet
420 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
423 New function, z_ext_record_oid_nmem, which is similar to
424 z_ext_record_oid but takes NMEM rather than ODR
426 --- 4.2.49 2013/01/18
428 ICU: New conversion element 'join' which joins tokens into one
429 with a custom character given by rule attribute.
431 --- 4.2.48 2013/01/10
433 New GFS search member: present_number. This is a hint to the
434 search handler how many records are going to be fetched immediately
435 following search. There's no guarantee that it's going to be the case,
436 since it depends on hit count (for Z39.50 piggyback) and whether errors
439 Make a few functions static (private). The functions getbyte_stream,
440 ungetbyte_stream and yaz_gets are now private. They were never declared
443 yaz-marcdump: exit(5) for serious decoding errors
445 ISO2709 decoding: be more picky WRT header
447 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
448 was only used as to indicate that next-result-set-position should be
450 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
451 Based on patch from Ashley Sanders.
453 Make some functions static/private in PQF parsing. Those functions were
454 never declared in a public header and so should not be in use by
455 applications based on YAZ.
457 --- 4.2.47 2012/11/23
459 ZOOM: special options to control APDU logging.
460 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
461 logging of APDUs until "saveAPDU" option is set again. If logging is
462 already enabled the effect is that current APDU buffer is cleared.
463 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
464 logging (default behavior on new connection).
465 The APDUs sent/received can be obtained by using
466 Using ZOOM_connection_option_get(c, "APDU") or
467 ZOOM_connection_option_getl(c, "APDU", &l).
469 GFS: relay implementation_version from backend
470 From 3.0.40 and later, implementation_version from backend was
471 not used in init response at all.
473 --- 4.2.46 2012/11/15
475 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
476 mode at all. Probably never did.
478 Make a new version of ztest.pem that, at least, is not expired.
480 --- 4.2.45 2012/11/13
482 Fix description of CCL directive 'case'.
484 More tight checking of form arguments (yaz_uri_to_array). Makes
485 YAZ better at rejecting big and/or bad POSTs.
487 SRU decoding does not report more than up to 10 invalid arguments.
489 rpn2cql: less quotes in generated terms. Semantics unchanged, but
490 it's prettier this way.
492 --- 4.2.44 2012/10/25
494 New utility yaz_decode_init_diag. Defined in proto.h.
496 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
497 given for unix local socket.
498 The COMSTACK string for doing so is:
501 unix:/myfile:tcp:localhost:9999/mybase
502 unix:/myfile:localhost:9999/mybase
503 unix:/myfile:http://fakehost/mybase
505 debian: Use dpkg-buildflags in build process.
507 --- 4.2.43 2012/10/19
509 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
510 global's SRU service uses a recordPosition scheme starting from zero.
511 First record's position should be one
512 according to the standard.
514 --- 4.2.42 2012/10/18
516 Allow more namespaces for SRU. This is to allow, for example, an
517 incorrect namespace returned from server
518 http://services.igi-global.com/sru .
520 Minor fixes for compilation on Windows.
522 --- 4.2.41 2012/10/11
524 daemon: log total number of bad signals from child on stop so that it
525 is more easy to spot problems with child worker processes.
527 retrieval: empty backend name attribute omits element set
528 from being used in retrieval.
530 --- 4.2.40 2012/10/04
532 Implement Solr sort strategy "solr", similar to sru11 sorting.
533 This will implement the correct parameters on Solr requst to do
536 --- 4.2.39 2012/09/28
538 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
541 MARC: Extra/missing indicator handled for MARCXML.
542 The indicator length is given in header and is the same for the
543 whole record. If attributes ind1, ind2 are missing, then content
544 character defaults to blank. Extra indicator attributes (beyond)
545 indicator length are treated as an error.
547 Reformat: delete trailing whitespace
549 --- 4.2.38 2012/09/17
551 MARC: fix non-ASCII characters for leader. This is to ensure we can
552 generate XML in UTF-8.
554 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
555 in one node with structure word.
557 --- 4.2.37 2012/09/04
559 yaz-json-parse: JSON output may be pretty printed by using option
562 Increase default value of max message for Z39.50 Init for GFS, ZOOM
563 and yaz-client. Old value was 1 MB. New value is 64 MB.
565 --- 4.2.36 2012/08/22
567 yaz-client: don't display bogus records from SRU servers. Some SRU servers
568 return more records than given by *maximumRecords*. Skipping those in
571 record_render: simplify buffer return handling and fix at least one bad
572 memory reference, that broke the test_embed_record sometimes.
574 Allow http://user:pass@host notation for yaz_url_exec.
576 zoomsh: allow shell command to be executed. Via the system(3) call.
578 yaz_poll: Allow num_fds == 0
580 yaz-client: fix bad encoding of "itemorder item". The itemorder
581 item <no> - command forgot to use length of encoded Item Request
582 package. Error present since YAZ 3.
584 yaz-ztest: fix bad usage of session handle. Bug was introduced when
585 result sets were saved (271a9c83).
587 SRU recordPacking: guess record packing in response rather than looking
588 at the recordPacking element which, OF COURSE, changed semantics in SRU
591 Decode SRU 2.0 responses. The official namespace for responses, according
592 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
593 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
594 nature.com's server, however, usee namespace
595 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
596 we are now using a glob-expr to match up the namespace. ZOOM C and
597 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
598 I can not find a single real example showing the "real" namespace in
599 the documentation from OASIS. The namespace for requests is different
600 from responses, but this is not added to YAZ yet, when we don't encode
603 --- 4.2.35 2012/06/26
605 zoom/record_render: add support for Base64 decoding fo MARC records
606 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
607 which will decode base64 + ISO2709 marc-8 encoded material from text node
610 --- 4.2.34 2012/06/07
612 Add missing definitions ZOOM_resultset_get_facet_field_by_index
613 and ZOOM_resultset_facets_names.
615 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
618 Change APDU dump printing to avoid long leading blanks. For levels 16
619 or larger the level is shown and the indentation is truncated but
620 recursed with modula 8. This makes it still reasonable easy to read
621 - even for nested BER dumps.
623 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
624 return 0 (incomplete package) in case where the BER package was
625 considered too nested (return value of -2).
627 dumpber: lines of level 15 are not indented further. Two spaces per
628 indentation; indentation 15 or more is indented to a fixed indentation
629 and augmented with a level=<no> indication.
631 zoomsh: increase max size of command+args
633 GFS: No limit in RPN buf size in CQL to RPN conversion.
635 --- 4.2.33 2012/05/09
637 New function for daemon utility, yaz_daemon_stop .
639 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
641 --- 4.2.32 2012/04/25
643 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
644 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
646 --- 4.2.31 2012/04/23
648 YAZ daemon utility relays SIGUSR1 to child process.
650 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
651 would result in en empty database list - which in turn would result in
652 encoding failure for search.
654 Fix reading beyond string in yaz_sort_spec.
656 --- 4.2.30 2012/04/11
658 Add two new SRU diagnostics:
659 236: Access to specified database denied
660 1015: Init/AC: Maximum number of simultaneous sessions for Userid
662 Document the very useful ZOOM-C option "apdulog".
664 CQL to RPN: term may be passed through verbatim. This is enabled with
665 truncation.cql . The assumption being that the term is already CQL.
667 --- 4.2.29 2012/03/20
669 record_conv: leader spec may be given for marc element.
670 The leader spec is given as attribute leaderspec for element marc.
671 For example to convert a MARC21 record from MARC-8 to UTF-8:
672 <marc inputformat="marc" outputformat="marc"
673 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
675 record_conv: allow user-XSLT params. For example:
676 <xslt stylesheet="MARC21slim2DC.xsl">
677 <param name="myparameter" value="myvalue"/>
678 <param name="otherparameter" value="othervalue"/>
681 record_conv: fix error handling for missing marc charsets.
683 CQL: fix extra terms in wrong order.
685 --- 4.2.28 2012/03/06
687 record_conv: modify new API for conversion types. The conversion types
688 may be passed in new functions yaz_record_conv_configure_t and
689 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
691 Avoid mixed statement/variable declare; fixes compilation with Visual
694 --- 4.2.27 2012/02/28
696 Add non-standard SRU diagnostic: 235: "Database does not exist".
697 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
698 Update SRU to Bib-1 diagnostic maps accordingly.
700 CCL: add two new diagnostics for unsupported masking. The new
701 diagnostics are: "Embedded truncation not supported" and
702 "Single charcacter mask not supported".
704 --- 4.2.26 2012/02/23
706 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
708 --- 4.2.25 2012/01/11
710 Build YAZ for Ubuntu Oneiric.
712 CCL: allow parantheses for proximity operands. For example CCL query
713 (a) % (b) is now allowed.
715 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
716 marked dead, rather then being destroyed. If not, the session memory is
717 being free'd before the search/scan handler is finished. Also destroy
718 'request' memory in request_release rather than in various places,
719 which resulted in leaks from time to time.
721 --- 4.2.24 2011/12/21
723 cql_sortby_to_sortkeys: honor sort prefix.
725 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
726 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
727 The rpn2cql family of functions now always returns quoted CQL terms.
729 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
731 --- 4.2.23 2011/12/15
733 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
734 sequence is treated as one. For example, &&a=b&&&c& is identical to
737 --- 4.2.22 2011/12/05
739 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
740 APDUs for a connection to a WRBUF.
742 --- 4.2.21 2011/11/23
744 Fix cql_sortby_to_sortkeys. Completely broken before.
746 Make CCL's @truncation work again.
748 --- 4.2.20 2011/11/09
750 New ZOOM connection setting: tproxy. It's like proxy, but does not
751 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
752 to set resolved address + port for a connection outside ZOOM itself.
754 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
756 --- 4.2.19 2011/11/07
758 Fix uninitialized variable in Solr spell support (could cause SEGV
759 for SRU response decoding).
761 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
762 back-end's addinfo through into the ZOOM response addinfo.
764 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
765 they are separated by a colon and a space rather than simply
768 --- 4.2.18 2011/10/28
770 Add support for Solr spell-checking/suggestions through ZOOM.
771 If a Solr target has been configured correctly for spelling-checking
772 and suggestions, these will now be returned on the ResultSet option
773 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
775 --- 4.2.17 2011/09/28
777 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
778 with a flag whether to substitute escape sequences or not.
780 --- 4.2.16 2011/09/22
782 Fix nmem_strsplit_escape to substitute escape char properly.
784 New option for zoomsh -e , which makes it abort on first error and
785 return process exit code to indicate success/failure.
787 YAZ options utility supports special option -- which makes all it treat
788 all following arguments as non-options.
790 --- 4.2.15 2011/09/16
792 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
793 searched if absolute filename is given.
795 Fix conv_xslt() error-reporting when stylesheet is not found.
796 (The value of fullpath is meaningless in this situation.)
798 --- 4.2.14 2011/09/07
800 Fix problem in CQL sort node creation: un-initialized memory.
802 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
803 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
804 CQL sortby depending on whether Type-1 or CQL is actually sent to the
807 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
808 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
810 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
811 will make it possible to use both single-character mask (#) and wildcard (?)
812 in CCL . Throw diagnostic for left truncation because that is not supported
815 --- 4.2.13 2011/09/01
817 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
818 cases using escapes (\-sequences) and masking.
820 PQF parse fix: A trailing backslash followed by end-of-string (\0)
821 would result in a read one byte beyond string.
823 rpn2ccl may use Z39.50 masking for terms (t=z).
825 ICU check fix. Don't include library -lCrun on Solaris, unless present.
827 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
828 not --cppflags (which seeems like an error in icu-config).
830 --- 4.2.12 2011/08/27 RPM package only
832 cql2ccl: fix conversion of terms: operator characters were not
835 --- 4.2.11 2011/08/25 RPM package only
837 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
838 CCL parser will map both # and ? to their regular expression
839 quivalents (. and .*).
841 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
842 of reserved CQL characters.
844 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
845 is, so that they are passed through.
847 --- 4.2.10 2011/08/24
849 ZOOM SRU mode: more aggressive re-connect.
851 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
852 made available as a utility function, declared in <yaz/logrpn.h>
854 rpn2cql_structure() supports proximity nodes (except that the Type-1
855 proximity node's "exclusion" binary is ignored, as there is no way to
856 express that in CQL). Fixes bug #4564.
860 Fix SEGV that could occur if set command of zoomsh was given without
861 value (2nd argument).
863 Fix SEGV that could occur if unsupported transport was given for
864 COMSTACK - say https (when SSL was unavailable).
866 Build yaz-url on Windows too.
870 New utility to get web content. Header is url.h. A command line tool
871 yaz-url is part of the distribution and packages.
873 Fixes for SSL COMSTACK (when gnutls is in use).
875 New functions yaz_base64{encode,decode}. Header is base64.h.
879 ZOOM C includes HTTP response buffer as additional info if it fails
880 to decode the SRU response.
882 Make wrbuf_json_puts available.
886 zoom: throw diagnostic for invalid value for option "sru". Before a
887 bad SRU request was sent.
889 Adding new utility wrbuf_vp_puts.
891 Add cclxmlconfig.obj to win/makefile. It was missing completely.
895 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
896 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
897 redirect was used at the same time.
899 MARC line mode decoding: be less picky about length given - first
900 5 digits of header that is.
902 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
904 Changes to decoding of SRU records: a record with recordPacking=xml is
905 modified with a new root element <yaz_record> if the recordData contains
906 multiple children elements. This is to make the record XML parseable
909 RPN to Solr conversion: encode special characters.
911 Generic Frontend Server: fix uinitialized member, stepSize.
915 Fix a bug in SRU decoding of records.. The database records stored
916 had un-initialized memory, but it would only be seen with yaz_record_render
917 and type_spec="ext" .
919 Fix a bug in ccl_qual_dup introduced in 4.2.3.
923 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
927 Add new utilities to convert from CQL to CCL . These utilities have
928 prefix cql_to_ccl defined in cql.h.
930 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
931 lead to memory heap corruptions when ICU utilities were in use.
935 Make compilation work without Libxml2.
937 yaz-client: remove redundant blanks in display of searchResult-1 term
942 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
943 resulting CQL node (tree) in a new node CQL_NODE_SORT.
945 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
946 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
947 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
948 Note that the CQL sortby spec is only converted when the GFS is already
949 converting from CQL to RPN (cql2rpn element).
951 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
952 specify whether to collapse delimitors or not. The existing nmem_strsplit
953 do collapse (collapse parameter = 1).
955 Windows installer: For NSIS, set InstallDir depending on x86/x64.
957 Rename internal func yaz_use_attribute_create. While non-static, this
958 function is not declared in a public header.
962 Add -lCrun when linking with ICU on Solaris.
964 More quicks character set conversions for OPAC records.
968 fix problem with record_render: records were converted (character set
969 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
973 SRU: add methods for handling DADS SRU-proxy facets.
975 Separate OPAC record character set for ZOOM_record. yaz_record_render
976 allows a character set given as charset=from/opacfrom,to where 'from' is
977 the character set of a bibliographic record, 'opacfrom' is character set
978 of OPAC record and 'to' is the target character set.
982 yaz-client: show may XML format records. Command show followed by 'format'
983 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
986 src/stemmer.c: Avoid using unnamed union. It is not supported by some
989 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
992 Update yaz.spec to operate on both SLES11 / Centos 5.5.
994 RPM: Release includes 'indexdata' name. Use indexdata in release name so
995 this package can be distinguished from other vendors.
997 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
998 as determined by configure
1000 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1002 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1003 returns no error and no record, the present request is considered
1004 partial (only a subset of the records could be returned by backend), and
1005 so it is appropriate to set Present Status to partial-4.
1007 --- 4.1.2 2010/11/02
1009 Move yaz-config man pages to section 1.
1011 More documentation about Solr.
1013 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1014 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1015 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1016 peers on some Linux systems. However, in general that does not work
1017 so YAZ can not rely on that to work. Debian changed behavior in this
1018 respect from Debian lenny to Debian squeeze (still testing as of Oct
1020 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1022 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1024 --- 4.1.1 2010/10/05
1026 Fix yaz-config output: echo_source not set correctly by configure.
1028 --- 4.1.0 2010/10/05
1030 Solr Web Service support for yaz-client and ZOOM.
1032 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1034 --- 4.0.12 2010/08/17
1036 Z39.50 facet support. Facet specifications are passed for search in
1037 other-information with ASN.1 as defined in facet.asn and OID
1038 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1039 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1040 3 is limit (number of entries to get in response). yaz-ztest returns
1041 dummy facets if a client asks for them.
1043 --- 4.0.11 2010/07/09
1045 CCL fixes: bug 2895 and bug 3539.
1047 GR1-display: add comma in display - was removed by mistake in
1050 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1052 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1054 --- 4.0.10 2010/06/18
1056 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1057 result set from a connection. The result set will be on its own
1058 thereafter; no operations on it will perform retrievals from a target.
1059 Only cached copies are returned.
1061 ZOOM C:fix case for HTTP servers responding with Connection:close.
1062 Ensure that if there is a current task it is resumed (like fetching
1063 more records in a result set) . Bug #3484.
1065 PQF parser: use odr_atoi for Odr_int (not atoi)
1067 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1068 values that contain any non-digits are treated as string attributes
1069 (previously decoding only checked for leading character ([0-9]). PQF
1070 encoding: attribute string values are not surrounded by double-quotes.
1072 --- 4.0.9 2010/05/21
1074 New utility for managing threads - thread_create.h.
1076 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1077 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1078 but YAZ' implementation do.
1080 Fixes for yaz_cond-functions on Windows 7.
1082 DLL export more symbols.
1084 zoomsh: show record do NOT render opac.
1086 Remove *.la files from Debian and RPM packages.
1088 --- 4.0.8 2010/05/11
1090 Debian package libyaz-dev depends on libgnutls-dev again (was
1091 removed in YAZ 4.0.6, but due to Libtool it is still needed
1092 even though yaz-config do not list libgnutls libs).
1094 ZOOM: Use only one WRBUF for returning string results for
1095 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1097 ZOOM: ZOOM_connection do not use a shared pointer to
1098 ZOOM_resultset after ZOOM_resultset is destructed by
1099 user. Reverts to YAZ 4.0.4 behavior.
1101 --- 4.0.7 2010/05/04
1103 record-conv: fix problem with at least one XSL conversion -
1104 due to probably incorrect usage of XML XSL documents.
1106 --- 4.0.6 2010/04/29
1108 Fix yaz-config for static mode and the use of SSL (gnutls).
1110 --- 4.0.5 2010/04/29
1112 Forward decl timeval struct in mutex.h and gettimeofday.h.
1114 yaz-config: fix 'static' mode linking.
1116 --- 4.0.4 2010/04/28
1118 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1119 are wrappers for pthreads or Windows. For Windows these are put in
1120 a separate DLL: yaz_cond4.
1122 libyaz.la (whole source) is compiled with thread. If thread support
1123 is enabled enabled, all source of YAZ is compiled with treading support.
1124 This allows core utilities such as yaz_log to use thread facilities.
1125 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1126 thread utilities. This commit moves mutex utilities (mutex.c) from
1127 libyaz_server.la to libyaz.la.
1129 yaz-json-parse displays leading text until error.
1131 --- 4.0.3 2010/04/09
1133 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1134 patch from Giannis Kosmas.
1136 SRU: no longer URL encode SRU database. The URL for an SRU server is
1137 a URL and such is alreeady encoded - at least when given with leading
1138 http:// or https://. This reverts behavior to YAZ 3.0.50.
1140 Support for new MARC XML notation TurboMARC which like MARCXML is a
1141 complete representation of MARC/ISO2709.. This one, however, is more
1142 compact and allows for faster processing with XSLT. TurboMARC can be
1143 used in the marcdisp.h API, from the yaz-marcdump utility and from
1146 yaz-ztest can be configured - via the database - to perform certain
1147 delays when it performs operations search, present and single record
1148 fetch. This allows testers to make yaz-ztest act as a real or even slow
1149 Z39.50 server. Refer to the yaz-ztest man pages for details.
1151 --- 4.0.2 2010/03/09
1153 wrbuf_destroy allows NULL WRBUF passed to it.
1155 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1157 Add ZOOM_connection_close.
1159 No fixed size buffers for ZOOM shell - bug #3257.
1161 tstodr: make it work on s390 platform.
1163 New icu iterator-functions. The new icu_iter-functions makes it possible
1164 to use ICU chains from many threads.
1166 yaz-client: better syntax check for show command.
1168 --- 4.0.1 2010/01/26
1170 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1173 New simple local-file XML include facility which allows file glob-patterns.
1174 Refer to yaz/xml_include.h.
1176 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1179 ZOOM_record_get supports new parameter "format" which makes it format XML
1182 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1183 JSONText in ECMA-262) is JSONValue, not JSONObject.
1185 --- 4.0.0 2010/01/20
1187 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1188 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1190 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1191 POSIX/Unix builds .so with major version 4.
1193 Remove old LOG_-defines from log.h. They have been obsolete and
1194 undefined by default for the last 5 years.
1196 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1198 GFS: Remove socket (int *fd) from search_rr handler. The socket
1199 descriptor ptr is a facility that allowed a search handler to supply
1200 a socket which would serve as a callback - when search was complete.
1201 This facility has now been in use for years.
1203 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1204 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1205 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1206 returns 'const char *' rather than 'char *. The returned string is
1207 read-only and should not be modified by applications. COMSTACK cs_close is
1208 now a void function - it no longer returns int. No applications check for
1209 the value and the implementations has always returned 0.
1211 ZOOM: use size_t for scan hit counts and str size. Functions
1212 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1213 occ (hit count) and len (string length) are now of type size_t pointer
1214 rather than int pointer. This is to be able to represent large hit counts
1215 and to also just to use the proper type for string length (strlen result).
1217 New JSON parser. Refer to include/yaz/json.h .
1219 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1220 Used to be int in some cases. Many wrbuf_-functions used to return an int
1221 indicating some length.. These return values were never used. And so they
1224 ODR: odr_malloc, odr_total now takes size_t for size.
1226 clone_z_type: fix leak; occurred for encoding failures.
1228 --- 3.0.52 2009/12/03
1230 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1231 bug was introduced in 3.0.51.
1233 --- 3.0.51 2009/12/02
1235 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1237 tcpip comstack: fix leak for getaddrinfo.
1239 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1240 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1241 Decoding of SRU "path" database is performed by private function
1242 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1243 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1245 yaz-client: honor base command for SRU. Change when database setting
1246 is applied for SRU and ensure it is kept when a connection is reset.
1247 Change also the way errors are displayed or SRU (decoding of packages).
1249 --- 3.0.50 2009/11/02
1251 Add support for extra request / response data for SRU codecs and GFS.
1252 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1253 for extra data response buffer and length. For the GFS, both request
1254 and response data (XML) is carried in extra_args and extra_response_data
1255 for the search handler. Patch by Ko van der Sloot.
1257 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1258 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1259 10010). This fixes bug #2113.
1261 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1262 cmdfile included a 'quit' command that would result in a memory violation.
1264 --- 3.0.49 2009/10/01
1266 Make a number of functions defined in xmlquery.c static. These have
1267 never been declared in a public header file (yaz/xmlquery.h) and was
1268 made public by mistake.
1270 Improve speed of character conversions (iconv utilities). This makes
1271 conversions from MARC-8 faster.
1273 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1274 unless type desired is "raw". This will prevent type "xml" from
1275 returning ISO2709 .. Which obviously can not be XML parsed.
1277 Fix memory leak in ZOOM that would occur if option apdulog was used
1278 on a re-used connection.
1280 Frontend server logs HTTP requests.
1282 Frontend server now sends Z39.50 close when it times out (sesssion has
1283 been idle for too long). Versions 2.0.30 and earlier also sent close.
1284 But due to a mistake this was disabled in all versions after that, i.e.
1285 the server would just close the socket immediately.
1287 yaz-client emits a better message when receiving an unrecognised
1288 userInformationField.
1290 Skip zero-length subfields when decoding ISO2709. This rare case happens
1291 if a record has two FS characters in a sequence. Without this patch
1292 there would be a reference beyond char array in using_code_len fragments
1295 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1297 --- 3.0.48 2009/08/28
1299 The show command offered by the zoomsh command now takes a 3d optional
1300 parameter type which is what is passed to ZOOM_record. If the type
1301 argument is omitted, "render" is used.
1303 RPN to CQL conv may use USE string attributes (bug #2978).
1305 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1307 --- 3.0.47 2009/07/08
1309 Function yaz_xml2query allows a diagnostic element in the PQF XML
1310 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1311 code and additional info respectively.
1313 The BER BOOLEAN is now the integral type Odr_bool which still happens
1314 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1315 typedef'd to Odr_int. This is still an integral 'int', but it may be
1316 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1317 ASN-1 compiler as well as programs has been updated to use the new types.
1319 --- 3.0.46 2009/06/08
1321 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1322 only the bibliographic record was rendered. For type=opac, an OPAC
1323 record is only returned if it is present.
1325 iconv: small fix for encoding of advancegreek.
1327 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1329 yaz-client: option auto_reconnect=on really reconnects.
1331 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1333 server: avoid null ptr ref for for yaz_poll errors.
1335 build: fix RPM build for RHEL 5.3.
1337 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1339 --- 3.0.45 2009/03/31
1341 Fixed bug #2709: TCP connect returns Invalid argument.
1343 Fixed compilation for mingw.
1345 Honor charset for raw records (ZOOM_record_get).
1347 Fixed use of errno for threaded mode that was seen on Solaris 10.
1349 Fixed argument passing with blanks in value for Windows Service.
1351 Disable YAZ' own log rotate by default (no 1 GB limit).
1352 The variable l_max_size which specifies the log file limit is set to 0
1353 (DISABLED): This is due to the fact that YAZ is most often deployed using
1354 logrotate. Also YAZ can not perform log rotate because of unsufficient
1355 permissions (setuid).
1357 --- 3.0.44 2009/02/17
1359 List supported encodings in man page for yaz-iconv.
1361 Fixed missing SSL libs for --libs output
1363 Re-established OID record syntax application-xml. Nobody should use it
1364 but we don't want to change soname because of this symbol being absent.
1366 --- 3.0.42 2009/02/02
1368 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1370 Added member named_result_sets for init handler struct for the GFS. This
1371 allows a server to disable named result sets.
1373 Removed OID record syntax application-xml.
1375 Added support for rule-based transliterator for ICU wrapper of YAZ.
1377 Fixed bug #1902: yaz-icu XML output.
1379 Make YAZ checks Emacs friendly.
1381 BITSTRING value shows value. Bug #2346.
1383 ISO2709 decoding: skip control characters from indicator data.
1385 Omit sort key by default in yaz-icu's output.
1387 Allow combined single char options (again) for YAZ' options function.
1389 Utility yaz-marcdump got option to display YAZ version (-V).
1391 Allow YAZ to use ICU 3.4.
1393 Added new ICU test case which illustrates removal of diacritics.
1395 --- 3.0.41 2008/12/29
1397 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1399 --- 3.0.40 2008/12/29
1401 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1404 Fixed bug #2352: yaz-marcdump crashes for certain record.
1406 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1408 Added support for Danmarc2 to UTF-8 conversion.
1410 Added support for ISO5426 to UTF-8 conversion.
1412 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1413 implementation version.
1415 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1417 --- 3.0.38 2008/11/10
1419 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1420 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1422 ZOOM C now interprets databaseName option for ZOOM connection as path
1425 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1427 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1429 Dummy Libxml2 types no longer defined in headers of YAZ'.
1431 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1434 --- 3.0.36 2008/09/26
1436 Various ODR chapter fixes.
1438 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1440 Added missing source for Windows compilation, mutex.c.
1442 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1444 For SRU connections in ZOOM all records up to "count" are now fetched.
1446 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1447 in Windows due to bad error handling for Libxml2.
1449 Added facility for sending arbitrary records (ASN.1 any) using
1450 ZOOM C's Extended service update. Patch by Sam Reynolds.
1452 New options for ZOOM C's connection, logapdu which makes ZOOM log
1455 --- 3.0.34 2008/06/18
1457 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1459 --- 3.0.32 2008/06/12
1461 Fixed memory violation that could occur when decoding UTF-8. This bug
1462 was only present in 3.0.30 of YAZ.
1464 --- 3.0.30 2008/06/06
1466 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1467 GNU TLS is used by default (if found).
1469 yaz-ztest returns OPAC records if a client asks for OPAC.
1471 Improved speed of MARC-8 encoding.
1473 Added support for lossy and loss-less MARC-8 encoding.
1475 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1477 Added new Windows Service wrapper (sc).
1479 yaz-client's itemorder command may now send a file.
1481 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1483 Added new function yaz_log_xml_errors.
1485 Allow (but warn) unknown XML attributes in MARCXML parsing.
1487 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1489 The UTF-8 to MARC-8 conversion now uses a different set of characters
1490 for Greek symbols. Bug #2120.
1492 --- 3.0.26 2008/02/21
1494 Added yaz_daemon (daemon.h).
1496 Fixed bug #2068: pkg-config trouble
1498 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1500 --- 3.0.24 2008/01/28
1502 Document --with-xml2 option.
1504 Added OPAC XML XSD (etc/opacxml.xsd).
1506 Allow glob mask for name attribute in retrieval element for the
1507 generic frontend server's retrieval facility.
1509 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1510 except POLLIN/POLLOUT.
1512 Fixed error handling in cs_listen. Bug #2037.
1514 --- 3.0.22 2008/01/20
1516 Fixed version in yaz/yaz-version.h.
1518 Fixed bug #2027: Crash when closing connection.
1520 Changed configure so that ICU support is only enabled if only ICU
1521 and Libxml2 is available (because the ICU chain is XML based).
1523 --- 3.0.20 2008/01/15
1525 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1526 is built. Only this DLL depends on the ICU runtime.
1528 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1529 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1531 Changed license of CCL module to 'Revised BSD'. After consultation with
1532 remaining members of the original EUROPAGATE consortium, we are re-issuing
1533 the CCL module without a separate license. The software was developed by
1534 Index Data as part of a research project. The special license was included
1535 to help feed usage information back to the project consortium to support
1536 project evaluation. At this time, the project consortium has long-since
1537 disbanded, and the majority of the original principals have retired. At the
1538 same time, we have significantly modified the software during the following
1539 years, to the point where very practically no original code remains. To
1540 simplify re-use of the software, we have contacted those members of the
1541 consortium who could be reached, and agreed to re-issue the module as a
1542 proper part of the YAZ package.
1544 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1546 CQL closer to being version 1.2 compliant. CQL also allows free-form
1547 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1550 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1551 bug could make Extended services handling crash in the ZOOM layer. This
1552 bug was only present in YAZ 3.0.18.
1554 --- 3.0.18 2007/12/19
1556 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1559 yaz-marcdump reads and writes collection wrapped records.
1561 Handle OPAC for record conversion module.
1563 Fixes for ICU wrapper.
1565 Allow ICU libs to be controlled with --with-icu .
1567 --- 3.0.16 2007/11/12
1569 Added yaz_poll which is a wrapper for select/poll. When poll is available
1570 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1571 sockets to be in use.
1573 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1574 functionality through an XML based configuration (ICU chain). This system
1575 is useful for search facilities such as Pazpar2 and Zebra that needs to
1576 perform tokenization of indexed material. The ICU code in a separate
1577 library libyaz3_icu.a.
1579 Added HTTP tunnel facility for COMSTACK, bug #1752.
1580 This is a facility that allows a Web proxy, such as squid, to tunnel
1581 Z39.50 traffic. This facility is "transparent" to must applications
1582 using YAZ. It's enabled by using pseudo transport connect: followed by
1583 the proxy address, followed by command, then follwed by he regular
1584 "virtual" addresss. For example,
1585 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1587 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1589 --- 3.0.14 2007/09/21
1591 Fixed bad memory reference in ZOOM_record - cuased by member not being
1592 initialized. This was a problem only in YAZ 3.0.12.
1594 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1595 fields were not removed.
1597 Changed the way C code is generated from codetables.xml. Made a MARC-8
1598 conversion trie for each characterSet section rather than codeTable.
1599 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1600 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1602 --- 3.0.12 2007/09/12
1604 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1605 from ZOOM_record_error).
1607 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1609 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1611 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1613 Better SRW-to-Bib-1 diagnostic mapping.
1615 ZOOM C and yaz-client announces SRU version 1.2 by default.
1617 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1620 Fixed in yaz_sru_decode to allow other version than 1.1.
1622 --- 3.0.10 2007/08/22
1624 Added support for SRU scan for ZOOM.
1626 Added support for the use of the older versions or Extended Service
1627 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1628 set to the version , 1=first, 2=second, 3=third. The third version is
1629 what ZOOM C has used so far. And that, obviously, is the default.
1631 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1632 therefore in Zebra and in SimpleServer-based applications). The new
1633 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1634 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1635 which is passed into the back-end search callback function.
1637 Added support for HTTP Basic authentication in clients: the SRU/W
1638 codec encodes the username/password elements of the PDU structure
1639 appropriately, and these may be set using the "user" and "password"
1640 options in ZOOM-C applications (the same options that are used for
1641 Z39.50 authentication).
1643 --- 3.0.8 2007/06/25
1645 Fixed bug #1208: SSL appears to be broken in ZOOM.
1647 Fixed bug #1206: Libxml2 include path weirdness.
1649 Added oid_name_to_dotstring.
1651 Allow elementSetName to be specified for ZOOM C record update.
1653 Allow waitAction to be specified for ZOOM C based for Extended Services.
1655 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1656 syntax OID. Bug introduced in YAZ 3 series.
1658 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1660 --- 3.0.6 2007/06/06
1662 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1663 directory. yaz-client now reads commands from file given by option -f
1664 if specified; then tries to read .yazclientrc in current directory.
1665 Failing that, it reads .yazclientrc from user's home directory.
1667 Added support for correlationInfo Note and ID for Record Update via
1670 Added yaz-client command querycharset which specifies character set for
1671 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1672 (termListAndStartPoint).
1674 Charset ISO5428:1984 is an alias for ISO5428-1984.
1676 Implemented a way to perform scan in a result set using Z39.50. This
1677 is achieved by attaching the result set name in the characterInfo
1678 (type InternationalString) of OtherInformation in the Scan Request PDU.
1679 The result set is identified in the otherinformation by the new OID:
1680 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1681 This allows for scan in result set and faceted search . Zebra did some
1682 of this in the APT term using attribute type 8 and value being result
1683 set. Using the OtherInformation approach for this is cleaner and easier
1684 to work with in proxies and the like. This facility can be used in
1685 yaz-client using new command setscan which takes a result set as first
1686 argument, start position (APT) as second.
1688 Changed decoding of SRU XML packed records to deal with servers that
1689 have recordData with XML data with multiple root nodes. Also make
1690 comparison for recordPacking case insensitive. Again, one server
1691 returns "XML" where others return "xml".
1693 For SRU responses allow Content-Type application/xml as well as text/xml.
1695 --- 3.0.4 2007/05/21
1697 Fixed bug in character set conversion of BER strings. Bug introduced
1700 --- 3.0.2 2007/05/08
1702 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1704 For OID class, use oid_class consistently.
1706 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1709 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1710 character set for bibliographic information interchange". By Giannis Kosmas.
1712 Added documentation on new OID API.
1714 --- 3.0.0 2007/05/02
1716 Changes to generic frontend server interface: added new member
1717 'query_charset' for bend_initrequest structure. A backend init handler
1718 should set this member to its native character set for query terms.
1719 When defined, the frontend server logic will announce this character set
1720 to a client if the negotiationModel bit is set by the client. All server
1721 implementors are encouraged to specify this. If a backend server does not
1722 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1724 Added CCL utility to remove terms (stop words) from resulting RPN
1725 tree. This is handled by functions with prefix ccl_stop_words_ .
1727 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1728 terms in RPN queries.
1730 Clean-up the CCL API. Moved some internal structures from ccl.h to
1731 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1732 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1733 This is replaced by ccl_parser_find_str which takes a string instead.
1735 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1736 libyaz.la is the core of YAZ except the generic frontend server and
1737 does not depend on POSIX threads anymore. libyaz_server.la is the
1738 generic frontend server facilities and uses POSIX thread functionality
1739 if available. The libyaz.la no longer depends on POSIX threads because
1740 the number of global structures is limited. NMEM no longer re-uses blocks
1741 between threads ; it simply free's memory immediately but allocates in
1742 "large" chunks as usual. We don't expect any performance penalties
1743 because of this. The yaz_log system is still using a global log_level so
1744 caution must be taken when modifying it with yaz_log_init_.. +
1745 yaz_log_mask_str. This, however, should not cause any trouble because
1746 these functions are called during initialization of application code
1747 anyway. `yaz-config --libs server` returns libs for server applications;
1748 `yaz-config --libs` returns libs for non-server applications.
1750 New OID database - with public definitions in oid_db.h. Removed old OID
1751 database including the head oid.h and definitions such as enum oid_value
1752 and struct oident. The new OID database uses the same string names as
1753 before but the 'protocol' is gone. There are now only two representations
1754 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1755 converts from string to OID; functions with prefix yaz_oid_to_string
1756 converts the other way.
1758 Change to emit_term() in CQL-to-PQF query translation: when a term has
1759 the /regexp relation modifier, do not process it for leading and
1760 trailing "^" and "*", which have quite different meanings in regular
1763 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1764 write handlers no longer carries a 'last' parameter. This will make
1765 yaz_iconv flush "less" characters. A flush is performed by call to
1766 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1768 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1769 removed, because function yaz_query_to_wrbuf does the same.
1771 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1772 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1774 Deprecated MARC utility functions removed.
1776 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1779 Branch split: YAZ_2_1_55_branch
1781 --- 2.1.54 2007/03/16
1783 Fix to ZOOM-C so that transparent reconnection is properly handled on
1784 connections that are in asynchronous mode.
1786 Fixed compilation on OpenBSD 4.0.
1788 Large strings in GRS-1 records are now properly displayed in yaz-client.
1790 Added character conversion support for "advancegreek"; based on patch from
1793 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1794 sequence is met. Before the error was not set so it would be unknown.
1796 Adjust yaz-marcdump MARC reader so that it skips until record separator
1799 --- 2.1.52 2007/03/07
1801 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1802 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1803 fd_set structure used as a bitmask for the FDs to be selected on.
1805 Using ACX_PTHREAD macro to check for POSIX threads.
1807 Fixed have-vsnprintf check.
1809 --- 2.1.50 2007/02/23
1811 Fixes for configure on BSD. Bug #900.
1813 Added snprintf/vsnprintf wrappers for systems that don't have
1814 limits (heavens forbid).
1816 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1817 created before all previous tasks were completed and removed from the
1818 task queue, the new task could be removed by a mistake.
1820 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1822 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1824 Fixed bug #832: Problem with MARC/charset in yaz-client.
1826 Fixed bug #668: save command line history for yaz-client.
1828 Fixed bug #830: pkg-config support.
1830 --- 2.1.48 2007/01/23
1832 Extended ZOOM result set options with two options that may be read by
1833 a client: resultSetStatus and presentStatus with values as specified for
1835 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1837 Fixed bug #827: Using SSL fails on Debian etch.
1839 Fixed bug #826: Weird looking chars for set of MARC records.
1841 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1842 that is treated as an ItemOrder with itemRequest being an XML document
1843 external. The value of "doc" is the content.
1845 Extended the GFS search facility. New member of bend_search_rr
1846 'estimated_hit_count' signals that hits is known to be an estmate
1847 (higher or lower than real hit count). New member 'partial_resultset'
1848 signals that the search was partial (hit count is lower or equal than
1849 real hit count). For Z39.50, the information is stored in resultSetStatus
1850 member of SearchResponse APDU. For SRU, the information is signalled
1851 via SRU diagnostic 59: "Result set created with valid partial results
1854 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1856 --- 2.1.46 2007/01/13
1858 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1860 Added ZOOM_connection_peek_event.
1862 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1863 the following new functions:
1864 ZOOM_event_nonblock, ZOOM_connection_process,
1865 ZOOM_connection_get_{socket,mask,timeout},
1866 ZOOM_connection_fire_event_{timeout,socket}.
1867 The existing blocking event handler, ZOOM_event, is a wrapper for the
1868 + blocking ZOOM_event_sys_{poll,select}.
1870 Implemented function ccl_xml_config which parses XML version of CCL
1871 configuration (bug #798).
1873 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1875 Added timings utility (yaz/timing.h)
1877 --- 2.1.44 2007/01/03
1879 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1882 Fixed bug #779: Rotation of apdu.log fails.
1884 Fixed for character set conversions:
1885 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1886 Honor G1 set in MARC-8 decoding.
1888 --- 2.1.42 2006/12/17
1890 Fixed bug #775: char conversion does not handle Alternative UTF-8
1893 Implemented function yaz_marc_read_line which parses MARC line format
1894 records. There is a wealth of formats out there. So far, this function
1895 reads line records produced by yaz_marc_write_line.
1897 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1898 more generic and easier to remember(!) options: -i format and -o format
1899 which specifies input format and output format respectively - where
1900 format is one of "marc", "marcxml", "line", "marcxchange".
1902 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1903 does not print anything except warnings for records.
1905 For yaz-marcdump, added support for MARC split into files (-s) with a given
1908 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1909 spec, at http://www.loc.gov/standards/sru/record-update/
1910 This has changed the binary layout of the following structs:
1911 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1912 bend_update_rr . Patch by Ko van der Sloot.
1914 Added GFS utility function bend_assoc_is_alive which returns 1 if
1915 association is still alive (client is connected); 0 otherwise (client
1916 closed connection). This allows busy servers to stop working for
1919 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1920 been a separate piece of software. This version of ziffy has been modified
1921 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1923 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1925 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1926 Client code may now interrogate options such as "init_opt_sort" to
1927 find out whether the server claims to support various options.
1929 --- 2.1.40 2006/11/27
1931 Added utilities yaz_{set,get}_esn to set/get element set name from
1934 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1935 of YAZ and has been so since YAZ 2.1.10.
1937 Implemented ZOOM_record_error which returns error information for
1938 record (surrogate diagnostic).
1940 --- 2.1.38 2006/10/31
1942 Updates for SRU Update by Ko van der Sloot:
1943 1. Changed name from "operation" to "action"
1944 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1945 versions in the code, marked as 'backward compatible'.
1946 3. Added diagnostics for SRU Update.
1948 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1950 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1952 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1954 For GFS, fixed problem with SRU diagnostic 'First record position out of
1955 range' being issued for 0 hits.
1957 zoomtst10 part of Windows Build.
1959 --- 2.1.36 2006/10/13
1961 Implemented yaz_filepath_comp which splits a path into file path
1962 components (required by Zebra 2.0.3+).
1964 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1965 BSD inspired license until now so this should not have any real impact on
1966 anybody. See http://www.opensource.org/licenses/bsd-license.php
1968 Fixed bug #687: Missing log lines.
1970 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1973 Fixed bug #689: SRU diagnostics to be added.
1975 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1976 whether a connection is idle (no more work do do).
1978 --- 2.1.34 2006/10/04
1980 Change type of optval from long to int for invocation of setsockopt with
1981 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1983 Added support for specifying the max log file size for the Generic
1984 Frontend Server. The size is given with option -r.
1986 --- 2.1.32 2006/09/21
1988 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1990 --- 2.1.30 2006/09/17
1992 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1995 Fixed bug in Generic Frontend Server that could cause a server to stop
1996 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1998 For the generic frontend server, the maximum record size is used as maximum
1999 size of incoming packages (SRU + Z39.50). The value until was previously
2000 only used in Z39.50 Init negotiation and, later, in a session controlled
2001 sizes of records returned. This is controlled using -k option. It can be
2002 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2004 --- 2.1.28 2006/09/04
2006 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2009 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2011 New option for yaz-marcdump -lpos=value which allows setting a portion
2012 of MARC header to a certain value.
2014 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2016 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2017 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2019 --- 2.1.26 2006/08/15
2021 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2024 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2026 --- 2.1.24 2006/08/08
2028 Fixed MARC ISO2709 encoding routines to deal with character set
2031 Minor changes to GFS logging. Database included in search request log
2034 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2035 cached/multiple records.
2037 Shared libraries are built by default on Unix+configure.
2039 Changed cql2pqf transformation to use a different evaluation order. The
2040 new order is: always, relation, structure, position, truncation, index
2041 and relationModifier. Old order was: always, relation, relationModifier,
2042 structure, index, position, truncation. Note that the the latter ones
2043 override former ones for identical attributes.. The new scheme means that
2044 it is possible to override any existing attribute with a relationModifier.
2045 And also that it is possible to override everything for the index rule
2046 (except the ones listed in relationModifier). No order is perfect but this
2047 one, we believe, covers more real cases.. The "always" should have been
2048 called "default", since the attributes there can be overridden with all
2051 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2052 compilation phase, but also for yaz-config --cflags output. This allows
2053 us to have public headers with Libxml2 stuff in them . It should also,
2054 eventually, make Libxml2 checks redundant in packages using YAZ, such
2057 --- 2.1.22 2006/06/15
2059 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2060 stored in uri, message and details.. Previously diagnostics were stored
2061 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2062 compatibility.. but he's probably the only one affected, so.
2064 Added support for CCL, compiled on the client side, in ZOOM-C. This
2065 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2066 input; the resulting query objects can be used for for searching with
2067 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2069 YAZ' configure searches for OpenSSL by default.
2071 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2072 SL_CTX_use_certificate_file. See
2073 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2074 for more info. Thanks to Ko van der Sloot.
2076 --- 2.1.20 2006/06/02
2078 Bug #600: SRU GET, POST support for yaz-client. Introduced
2079 command 'sru' which selects method SOAP/GET/POST.
2081 Allow missingValueAction to be specified for the sortspec string -
2082 function yaz_sort_spec. By default, the missing value action is null.
2083 Use ! to specify "abort". Use = followed by stringvalue to specify default
2086 Ensured that Present-handler (if defined) is called in GFS before any call to
2087 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2088 searchRetrieve requests.
2090 Documentation for YAZ is now based on the Docbook XML/XSLT using
2091 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2092 is no longer depending on jade/openjade or docbook-to-man scripts.
2093 PDF is no longer part of the distribution - but can optionally be
2094 made using DSSSL/jadetex or FOP.
2096 Added retrieval handling support in Generic Frontend Server to support
2097 conversion between MARC/XML as well as XSLTtransforms. See
2098 etc/yazgfs.xml for an example.
2100 Added Authentication support to Generic Frontend Server in SRU
2101 mode. Authentication using HTTP Basic is supported, as is the use
2102 of 'x-username' and 'x-password' parameters in the request itself.
2104 Added support for a new character set MARC8s identical to MARC8 except
2105 that it converts combined characters to single Unicode characters in the
2106 Latin-1 range (when possible).
2108 --- 2.1.18 2006/04/24
2110 ASN.1 compiler 0.4: generates brief Doxygen file header for
2111 generated .h/.c files.
2113 Utility yaz_iconv now supports conversion to MARC-8.
2115 New facilities for the MARC module. The reading - and writing of
2116 content are separate methods for the yaz_marc_t handle. The following
2117 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2118 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2119 format). Write functions have prefix yaz_marc_write_.. The existing
2120 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2121 available. Removed support for OAI-MARC and simplexml (not the
2122 simplexml from PHP5).
2124 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2125 to be returned for this connection.
2127 --- 2.1.16 2006/03/31
2129 Allow multiple languages and charsets to be specified with
2130 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2131 negcharset iso-8859-1,utf-8
2133 Translation of proximity nodes from CQL into PQF now works.
2135 Moved to automake 1.8, 1.9.
2137 Added function yaz_log_set_handler which allows a log handler to be
2138 installed. This handler will be called for all log messages. Output
2139 to file is also produced; but that can be disabled by passing NULL
2140 fname to yaz_log_init_file.
2142 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2144 For SRW (including GFS), accept application/soap+xml as content-type
2147 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2148 produces NO stylesheet reference even if a default stylesheet is specified
2151 --- 2.1.14 2006/03/14
2153 Updated Windows package to include yazd.dll + yazd.lib for the
2154 Development component.
2156 If the environment variable YAZ_LOG is set, then it is used as a
2157 string indicating the default level of logging to use if not
2158 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2159 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2160 used as before. So, for example, to omit warnings from YAZ logging,
2161 export YAZ_LOG=-warn
2163 cql_transform() now map structure and other attributes before indexes,
2164 so that index-specific structures and other attributes can override
2165 defaults. So now a combination of mapping specifications such as:
2167 index.dc.date = 1=date-modified 4=5
2168 does the right thing.
2170 cql_transform() now also respects the "always" mapping specification,
2171 which establishes an initial set of attributes to be used for all
2172 terms except where overridden by more specific attributes associated
2173 with the index, relation or modifier.
2175 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2176 which mode to use; one of "post", "get" or "soap" (SRW, default).
2178 Fixes for yaz_iconv routines: changed trie-based character set conversions
2179 to use only non-negative values for bit fields due to Sun's C compiler not
2180 supporting negative values.
2182 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2183 sequences where not read correctly. Fix by Rustam Usmanov.
2185 Updated win/makefile to use options, settings which makes things
2186 compile with VS C 2005.
2188 --- 2.1.12 2006/02/01
2190 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2192 In ZOOM socket code, use select instead of poll on MacOSX.
2194 ZOOM-C now support client-side compilation of CQL into RPN that is
2195 sent to the server, enabling CQL to be used against all Z39.50
2196 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2197 ZOOM_query object, and submit it using ZOOM_connection_search().
2198 The CQL-to-RPN translation uses a configuration file, the name of
2199 which must be specified in the Connection's "cqlfile" option.
2201 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2202 function, which takes as its start-term parameter a ZOOM_query object
2203 (which may have had either CQL or RPN set into it).
2206 --- 2.1.10 2005/11/29
2208 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2209 GFS to support this as well. Backend handler, bend_srw_update, does the
2210 update work. Code contributed by Ko van der Sloot.
2212 Allow retrieval of Search Result-1 information in ZOOM by the use of
2213 options that are attached to a result set. ZOOM documentation updated
2216 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2217 UTF-8 conversion. Patch by Raj Patel.
2219 Added option -m to GFS to control formatting of timestamps in log file.
2221 Added 'exit' as synonym for 'quit' in yaz-client
2223 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2224 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2225 for the new members. Patch by Ko van der Sloot.
2227 Added support for SRU POST. It is supported for content-type
2228 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2230 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2231 Instead make the library libyaz.la multi-threaded. Threading as a whole
2232 can still be disabled by configure option --disable-threads. Previosly,
2233 with older GLIBCs there were problems with MT libs under Apache. This
2234 has now been fixed a long time ago.
2236 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2239 CQL module modified to be case insensitive for relations/indexes/operations.
2241 Fixed bug in CQL transform code: incorrect value relationModifieder
2244 Added 'show all' command for yaz-client which retrieves all results
2247 Added new yaz-client, xmles, which takes a (private) OID and
2248 a document to be sent as an extended service request.
2250 Describe new yaz-client commands wait_response and set_auto_wait.
2252 Increase TCP/IP listener backlog from 3 (which I am guessing was
2253 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2254 that the socket will queue as many incoming connections as it's able
2255 to handle ongoing connections. In other words, it will never now
2256 refuse a connection that it would be able to handle merely because
2257 it's not got around to accepting() enough of the pending connections
2258 yet. This is the behaviour anyway under Linux, where the listen()
2259 argument is ignored; but not under BSD and on systems such as
2260 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2261 YAZ-based servers should now be uniform across operating systems in
2264 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2265 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2266 This allows yaz-marcdump to read large MARC batches (>2 GB).
2268 Modified all YAZ source files - except the source which is auto-generated
2269 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2272 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2273 corresponding to the existing *_setl() function. These allow option
2274 values containing arbitrary valuues.
2276 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2277 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2278 except that it returns an indicator of whether or not the sort
2279 criterion was accepted (0 for OK, -1 for invalid).
2281 --- 2.1.8 2005/06/07
2283 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2284 MARC output rather than returning "new" buffer.
2286 yaz-client warns about unknown init options.
2288 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2290 --- 2.1.6 2005/05/24
2292 Added support for SRW sort in Generic Frontend Server. Patch
2293 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2294 sortKeys - or NULL if none is provided.
2296 Fixed bug #307: It was impossible to specify indefinite/no timeout
2297 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2300 Added support for multiple languages and charsets to be specified in
2301 ZOOM. Each charset/language is separated by a blank. If negotiation is
2302 in effect in init-response, Option
2303 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2304 Code based on patch by Vasiliy Osadchuk.
2306 Fixed bug #306: infinite recursion that occurred when calling
2307 yaz_log_level_init as the first call (before other log level or
2310 Fixed bug in scan handling in front end server: if preferred-Position-In-
2311 Response was non-present, a NULL pointer referece was performed.
2313 --- 2.1.4 2005/04/26
2315 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2316 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2317 now defined for all those error codes. So instead of putting 109 in
2318 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2319 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2321 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2324 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2326 Program yaz-client now exits and produces an error message if multiple
2327 Z39.50 servers are specified on the command line (none or one allowed
2330 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2333 --- 2.1.2 2005/03/16
2335 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2337 Fixed bug #272: Preserve spacing for CCL terms.
2339 --- 2.1.0 2005/03/14
2341 Added support for virtual hosts and multiple backend servers for
2342 the YAZ frontend server. The configution is XML based and
2343 support specificition of CQL to RPN mappings and explain information.
2344 See section "Virtual Hosts" in the YAZ manual.
2346 Extended OPAC display utility. OPAC display utility renders
2347 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2348 to supplement yaz_marc_decode_wrbuf.
2350 Fixed a bug in MARC decoder that could caused it to crash for some
2351 invalid MARC records. More diagnostics and warnings where added in
2352 XML output (warnings, etc are stored in comments).
2354 --- 2.0.34 2005/02/08
2356 Fixes for UNIX domain sockets. Bug #261.
2358 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2360 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2361 Added yaz_marc_subfield_str which defines subfield lead string which is
2362 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2363 yaz_marc_endline_str which defines end of fields string used in
2364 YAZ_MARC_LINE format. Default string is newline.
2366 Experimental support for MarcXChange. This format can be produced
2367 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2368 http://www.bs.dk/standards/MarcXchange.xsd
2370 Added yaz-client commands scansize that sets maximum number of
2371 entries to be returned by scan.
2373 --- 2.0.32 2005/01/11
2375 Added support for SRW scan in yaz-client and Generic Frontend Server.
2377 * Added whereInList member to SRW Scan Term.
2379 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2381 Fixed NMEM system to return aligned blocks on the smallest boundaries
2382 that are suitably aligned for all possible types on the particular
2383 architecture YAZ is being built for.
2385 --- 2.0.30 2005/01/04
2387 Fixed numerious warnings that was issued with newer versions of GCC.
2389 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2390 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2393 Make YAZ Generic Frontend Server slightly faster.
2395 Enhance (and reduce) logging for Generic Frontend Server.
2397 Revert YAZ log system so that it flushes every write operation
2398 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2400 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2401 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2402 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2403 will effectively disable old definitions.
2405 --- 2.0.28 2004/11/09
2407 Added yaz_log_time_format which specifies log format using
2410 Added yaz_log_module_level which returns mask for a module. Value
2411 is non-zero mask a if module is enabled; zero if disabled.
2413 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2414 in include/yaz/cql.h.
2416 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2418 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2420 Fixed bug #172: RPM builds does not enable SSL.
2422 Doxyfile.in part of dist. Doxyfile generated by configure.
2424 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2425 are given and the corresponding component does not exist.
2427 Extend CCL documentation in YAZ reference. Describe r=r.
2429 --- 2.0.26 2004/10/01
2431 Fixed MARC->MARCXML conversion to properly deal with
2432 fields, subfields, indicators having non-ASCII characters.
2434 Fixed MARC->MARCXML conversion so that ASCII control characters
2435 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2438 Added YAZ GFS support for conversion from Z39.50 surrogate
2439 diagnostics to SRW surrogate diagnostics.
2441 Bug fix: YAZ GFS did not return schema in explainResponse.
2443 --- 2.0.25 2004/09/30
2445 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2446 now converts recordSchema to elementSetName as well as schema URI.
2448 Fixed bug in COMSTACK that prevented HTTP request packages from being
2451 --- 2.0.24 2004/09/29
2453 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2454 does not require white-space before and after the dash in a range, e.g.
2455 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2458 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2459 due to new GCC removing "redundant" code.
2461 Added yaz-client commands scanpos and scanstep that sets preferred
2462 position and step-size for scan.
2464 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2466 Added CCL utility ccl_qual_buf which parses one or more CCL
2467 spec lines in a buffer.
2469 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2470 of name and value - ignoring empty lines and comments.
2472 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2474 Added odr_get_element_path which returns current element path for an
2475 ODR handle. This utility is useful in error handling or user-defined
2478 Added ODR_PRINT utility odr_set_stream which is is a more generic
2479 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2480 to a write function and pointer to close function. The close function - if
2481 non-NULL - will be called during odr_destroy.
2483 Fixed bug in CCL parser where truncation char was not removed from
2484 right side when truncation=both was in effect.
2486 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2489 --- 2.0.23 2004/08/11
2491 Fix buffer overrun in CQL parser when dealing with proximity (%).
2493 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2494 to UTF-8/UCS conversion is now only based on codetables.xml.
2496 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2498 --- 2.0.22 2004/08/06
2500 Add support for more "commit changes" in ZOOM (uses Extended Services).
2502 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2505 Yet another small fix for configure of SSL.
2507 --- 2.0.21 2004/05/14
2509 Fix SSL libs for configure when --with-openssl=DIR is given.
2511 --- 2.0.20 2004/05/10
2513 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2515 SSL comstack now uses yaz.pem certificate file on server side
2516 by default. Certificate filename can be configured by calling
2517 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2519 Fix bug regarding multiple calls to ZOOM_connection_connect.
2521 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2523 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2524 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2526 ZOOM now allows inspection of X509 peer certificate for verification.
2527 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2529 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2530 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2531 as "modular" but it simplifies things.
2533 Added cs_get_peer_certificate to that returns peer X509 PEM.
2535 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2536 NULL if SSL is unavailable.
2538 Documentation about MARC decoding tools.
2540 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2542 --- 2.0.19 2004/03/30
2544 Rename CHANGELOG to NEWS to follow GNU style packing.
2546 Fix bug with missing initialization of member in init_diagnostics.
2547 This bug affects threaded version of GFS server.
2549 --- 2.0.18 2004/03/20
2551 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2554 Ensure zlib.dll is packed with Windows install.
2556 --- 2.0.17 2004/03/17
2558 Fix encoding of xsd:string to use text instead of CDATA.
2560 Fix endless loop in CQL parser with unbalanced ".
2562 Use a more compact way to store MARC-8 conversion tables.
2564 --- 2.0.16 2004/03/16 Debian only
2566 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2569 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2574 --- 2.0.15 2004/03/01
2576 Another fix for decoding of XML packed records.
2578 --- 2.0.14 2004/02/25
2580 Fixes for Chunked encoding. White space not ignored after length spec.
2582 Update NS and use default NS for SRW diagnostic elements.
2584 --- 2.0.13 2004/02/23
2586 Implement ZOOM_resultset_cache_reset which resets record cache.
2588 Implement ZOOM_resultset_sort which sorts a result set.
2590 Implement chunked HTTP transfer.
2592 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2594 --- 2.0.12 2004/02/16
2596 Added member 'schema' to bend_explain_rr structure so that backend
2597 can specify explain record identifier. Defaults to Zeerex 2.0.
2599 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2601 --- 2.0.11 2004/02/16
2603 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2606 Added init command for yaz-client which sends "extra" init request.
2608 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2609 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2611 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2613 Make ZOOM error code for "invalid query".
2615 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2617 --- 2.0.10 2004/02/05
2619 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2622 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2624 Added option -p <file> to make Generic Frontend Server to write PID file.
2626 Added option -D to put Generic Frontend Server in background on its own.
2628 Make ZOOM C recognize option "password". If unset, "pass" is used
2629 (for backwards compatibility).
2631 Fixed a bug in Generic Frontend Server that could make it crash if a
2632 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2635 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2636 Must be issued before open, in order to be in effect.
2638 --- 2.0.9-6 2004/01/12 Debian/Windows
2640 Make the SRU server more picky WRT unknown params, etc.
2642 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2644 New YAZ client command, options, that sets Z39.50 options.
2646 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2647 options from a string of tokens (one token for each option bit).
2649 Update SRW diagnostic code messages.
2651 --- 2.0.9-5 2004/01/07 Debian/Windows
2653 Handle user defined stylesheet for SRW/SRU.
2655 --- 2.0.9-4 2004/01/06 Debian/Windows
2657 Fix bug in decoding of Content-Length.
2659 --- 2.0.9-3 2004/01/06 Debian/Windows
2661 Fix a bug with decoding of XML packed records.
2663 --- 2.0.9-2 2004/01/05 Debian only
2665 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2667 Fix bug in SRW/SRU diagnostics decoding.
2669 --- 2.0.9 2004/01/05
2671 Fixed bug in Generic Frontend Server which could drop records exceeding
2672 preferred message size. Reported and fixed by Irina Dijour.
2674 Fixed calculation of package size for structured records in Generic
2675 Frontend Server. Reported and fixed by Irina Dijour.
2677 Fixed namespace for SRW/SRU diagnostics.
2679 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2681 --- 2.0.8 2003/12/22
2683 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2684 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2687 CQL changes to reflect recent changes to the specification:
2688 * Documentation talks about context sets instead of index sets.
2689 * Documentation talks about indexes instead of qualifiers.
2690 * The CQL-to-PQF transformer's configuration file now uses
2691 "index.set.name = <attributes>" instead of the old form
2692 "qualifier.set.name = <attributes>". (Both forms are still
2693 understood but the latter is deprecated.)
2694 * CQL terms with no explicit index specified are now interpreted as
2695 cql.serverChoice instead of srw.serverChoice (which of course
2696 behaves exactly the same.)
2698 --- 2.0.7 2003/12/16
2700 MARC conversion can now generate ISO2709 output in another
2701 character set. yaz-marcdump uses this facility if you invoke it
2704 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2705 functions from there can be used from C++.
2707 --- 2.0.6 2003/12/04
2709 Frontend server now transfers memory from decoded packages to stream
2712 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2713 references to show up.
2715 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2716 the ZOOM Abstract API. The older names for the same options are still
2717 also supported for the benefit of old applications.
2719 ZOOM-C supports "implementationId" and "implementationVersion" options
2720 to go along with "implementationName". These allow the user code to
2721 specify identification strings to be sent to servers.
2722 Add OID for the new ExtLite attribute set.
2724 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2725 as requested/supplid by Ere Maijala <ere@atp.fi>
2727 For generic frontend server, reverse the order of
2728 "toolkit-supplied / application-supplied" strings sent as implementationId,
2729 Name and Version. Also, remove the spaces around the slash. This brings
2730 the GFS in line with the behaviour of ZOOM-C on the client side.
2732 Add function ZOOM_scanset_display_term.
2734 yaz-client shows scan displayTerm if present.
2736 Utility yaz-iconv is now installed by default along with the man page
2739 Extend configure check for OpenSSL to use pkg-config where available (such
2742 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2743 server to specify uid/gid/mask for socket using the format
2744 unix:[user=uid,][group=gid,][umask=mask,]file=path
2745 If file= is omitted the existing format is assumed, e.g.
2747 in which case the mask is 0666 (rw for everybody).
2749 Major restructure of YAZ source. All source in libyaz is in src directory.
2750 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2751 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2753 Added man page for utility yaz-marcdump (used to be called marcdump).
2754 yaz-marcdump is installed by 'make install'.
2756 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2757 of incoming package failed.
2759 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2761 Change prototype of odr_perror: add const to message string.
2763 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2765 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2766 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2767 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2768 DNS lookup. There should not be any compatibility problems with this
2769 assuming that blocking=1 or 0 is used.
2771 Fix bad reference in UNIX comstack in function cs_addrstr.
2773 Fix for compilation on AIX.
2775 The generic front-end server (server/seshigh.c) now supports returning
2776 Init diagnostics to the client in User-information-field, in
2777 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2780 --- 2.0.4 2003/09/04
2782 Allow any CQL relation (not just all,any,exact,scr).
2784 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2785 that features the same UI.
2787 Implemented command update0 in YAZ client which is equivalent to
2788 update but uses old of Ext Update ASN.1.
2790 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2791 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2792 Previously no OID was used for this info.
2794 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2795 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2796 returns 'malformed search term' otherwise.
2798 SortResponse member resultCount now set to NULL in sort handler of
2801 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2804 Add three new utility functions for translating OIDs between various
2805 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2806 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2807 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2808 char *oid_to_dotstring(const int *oid, char *oidbuf);
2809 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2811 Reverted modifications for ES Update definition for z_IU0Update
2812 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2813 is back to YAZ 2.0.2.
2815 String value attributes for CCL parser.
2817 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2818 which their FirstSearch server returns in Init responses, sometimes
2819 carrying useful diagnostic information when Init fails. This has the
2820 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2821 "z39.50/oclcui.asn", where its definition is somewhat different from
2822 what OCLC document on their web-site, as required to interoperate with
2825 Support for anonymous authentication in yaz-client. Use the command
2828 * Fix the OID of the Index Data-local "admin" Extended Service from
2829 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2830 the 1000, which indicates a locally-defined OID, was a mistake.
2832 --- 2.0.3 2003/06/20
2834 Fix CCL directive @case handling so that it affects string match for
2835 both CCL keywords and qualifiers.
2837 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2838 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2839 Decoder has been updated with ASN.1 changes as listed in
2840 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2841 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2842 z_IUUpdate, remains unchanged.
2844 ZOOM_record_get may now return a record in a specific character set.
2845 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2846 "from" is the character set of record as returned by target. "to" is
2847 the character set to be returned. If omitted, "to" is UTF-8.
2849 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2851 New ODR utility, odr_getelement, which returns name of element for
2852 which encoding/decoding failed.
2854 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2855 in cases where a required element was omitted.
2857 Bug fix: some MARC8 sequences were not converted.
2859 New ZOOM option "step" which specifies number of records to be
2860 retrieved in one chunk. Used in conjunction with "start" and "count".
2862 SRW support for yaz-client. Use scheme http: to use it, e.g.
2865 yaz-client no longer does (un)intelligent character set conversions
2866 by default. Can be enabled with charset and marc_charset commands.
2868 xmalloc trace fix for 64-bit systems such as DEC alpha.
2870 Solaris 2.6 compile fix.
2872 New function, cql_strerror() translates SRW error codes, as returned
2873 by cql_transform_error(), into human-readable English strings. Used
2874 in yaz-client diagnostics when appropriate.
2876 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2877 converts it into a type-1 query which is sent to the server. This
2878 makes CQL available for use with all Z-servers, as opposed to the tiny
2879 minority that can handle CQL queries themselves.
2881 --- 2.0.2 2003/04/28
2883 New Debian package layout similar to the Redhat Package layout.
2885 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2886 and search result respectively.
2888 --- 2.0.1 2003/04/25
2890 Redhat package is now several packages: libyaz (runtime libraries),
2891 libyaz-devel (development and documentation, and yaz (utility programs).
2892 Package spec file by Morten Bogeskov.
2894 New member 'schema' in struct bend_fetch_rr which the name of requested
2895 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2896 handler MAY set this to reflect the schema of the returned record.
2898 New member 'display_term' in struct scan_entry. GFS now sets member entries
2899 and allocates scan entries to be filled by user scan handler. In previous
2900 version, entries member was allocated by the scan handler. That still works,
2901 but the GFS will ignore member display_term - assuming it was NOT set by
2902 the handler. The fact that the GFS now allocates the entries both allows
2903 for new members and makes a scan handler easier to write.
2905 Fix CQL lex buffer overflow.
2907 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2908 SRU default recordPacking is string.
2910 SRU protocol support for frontend server.
2912 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2914 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2916 Added scan for the ZOOM shell (zoomsh).
2920 * String Identifers for Schemas (Amendment 5).
2921 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2922 Old definition for schema
2923 Odr_oid *schema; /* OPT */
2928 Z_InternationalString *uri;
2929 #define Z_Schema_oid 1
2930 #define Z_Schema_uri 2
2933 * resultCount parameter to Sort Response (Amendment 1).
2934 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2936 Support for SRW 1.0 over HTTP. This is an optional feature and
2937 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2940 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2941 on the same port. SRW SearchRetrieveRequests are mapped
2942 to bend_init,bend_search,bend_fetch,bend_close.
2944 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2946 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2947 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2949 ZOOM connections are SRW based if schem http is used for hostname
2950 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2951 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2953 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2954 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2955 distance=n, order=true/false, relation=le, prox unit=word. If
2956 n is omitted, distance 1 is used.
2958 Fixed problem with C compiler include path in wrong order.
2960 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2961 on Solaris. Patch from Ko van der Sloot.
2963 New MARC decode API. All new functions operate on a yaz_marc_t
2964 handle. The most important new functions are: yaz_marc_create,
2965 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2966 decode and destroy respectively. Decoder can produce formats
2967 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2968 include/yaz/marcdisp.h.
2970 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2971 to UTF-8, UCS-32, wchar_t or Latin-1.
2973 * Prototypes for yaz_iconv_-functions moved to separate header
2974 include/yaz/yaz-iconv.h.
2976 Make a few private functions 'static' in unix.c. This prevents
2977 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2979 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2980 are set when Init Response is received.
2982 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2983 but returns diagnostic set as well.
2985 New function yaz_strerror which is a portable wrapper for
2986 strerror/strerror_r/GetLastMessage.
2988 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2989 is returned for MARC. If type is "oai", then OAI MARC is returned.
2991 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2994 --- 1.9.2 2002/11/26
2996 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2998 Fix bad race conditions on SIGTERM and terminate gracefully in
3001 Move retrieval (data1) module to Zebra since nobody seems to be
3004 Add GRS-1 render for ZOOM using same format as yaz-client.
3006 --- 1.9.1 2002/10/05
3008 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3010 Fix broken ESpec handling in data1 module.
3012 SGML reader parses comments and makes them part of the data1 tree.
3014 Added several type casts so that YAZ compiles as C++ code.
3016 ZOOM didn't handle PDU encoding failures properly.
3018 Added more Bib-1 diagnostics (approved extensions).
3020 GNU configure: better check for iconv.
3022 More portable use of accept, getpeername. Check for socklen_t. Use
3023 int/size_t if socklen_t is not defined.
3027 PQF parser rejects bad queries - including those with extra
3028 characters in them. PQF parser used to silently ignore that.
3029 Cleaner API for PQF added, which allows you to get detailed
3030 error information for bad queries (see yaz/pquery.h).
3032 Fixed bug in ZOOM_record_get for type "database".
3034 Implemented mini iconv library supporting conversions between
3035 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3037 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3039 --- 1.8.9 2002/08/20
3041 Fixed ZOOM C record cache so that preferredRecordSyntax and
3042 elementSetName is used to check for already fetched records.
3044 --- 1.8.8 2002/08/02
3046 Added three members in bend_initrequest structure to facilitate
3047 character set negotiation.
3049 Fixed a bug in frontend server that could cause indefinite
3050 loops under rare conditions.
3052 Revised character set utilities (charneg.h) so that encoding
3053 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3055 For PQF, directive @term <type> sets term type for Scan/Search.
3056 Here <type> is general, string, numeric, null. The term type
3057 is inherited - just like @attr.
3059 New call odr_set_charset that sets character set conversion for
3060 international-strings on a ODR stream. Prototype is:
3061 int odr_set_charset(ODR o, const char *to, const char *from);
3062 The InternationalString is still represented as C string in YAZ
3063 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3064 won't). On the protocol level, you can use any encoding.
3066 Support for UNIX sockets in ZOOM.
3068 Solaris recv sometimes returns errno == ENOENT. It is treated as
3069 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3071 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3072 both client and server. Code by Morten Bogeskov.
3074 --- 1.8.7 2002/05/22
3076 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3077 that they can be used directly from Visual Basic. You must recompile
3078 your windows APP if you're using ZOOM.
3080 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3081 Commands "lang" and "charset" sets language and character set respectively.
3082 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3083 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3085 Attributes from multiple CCL fields may be OR'ed rather than merged
3086 using directive "@field or". Fields are still merged by default -
3087 equivalent to "@field merge".
3089 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3092 Fixed bug in zget for parameter ExtendedServicesResponse.
3096 --- 1.8.6 2002/03/25
3098 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3100 Client displays USR.1:SearchResult-1 (hits per term).
3102 Additional Search Info for search in Generic Frontend Server.
3104 Fixed CCL parsing of "field=s".
3106 WIN32 installer - using the excellent NSIS software from nullsoft.
3108 Fixed CCL parsing of "field = - <number>".
3110 Added function yaz_marc_decode that decodes MARC for line mode
3111 display or XML (similar to that used by JZKit).
3113 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3114 Z39.50. But ISO/ILL was, however.
3116 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3117 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3119 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3120 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3122 --- 1.8.5 2002/02/03
3124 New YAZ client features: Command completion and new commands:
3125 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3126 Code provided by Jacob Poulsen.
3128 New call oid_trav, that visits all registered OIDs via callback.
3130 Function ZOOM_record_get now returns const char pointer rather than
3131 void pointer. It saves a lot of type casts.
3133 For YAZ client, command "auth" now allows you to set authentication
3134 in IdPass style. It is enabled when three tokens are given - order
3135 is user, group and password.
3137 Fix memory leaks in MARC record handling for ZOOM.
3139 New option for YAZ client, -k <kilobytes> that sets
3140 maximum record size. Similar to -k option for generic frontend
3141 server and yaz-ztest.
3143 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3145 Prefix query parser reports "fail" when bad attribute set is given.
3147 Fix in MARC decoder. Proximity logging. Fix for attribute set
3148 in scan handler for server. Patches by Shigeru Ishida.
3150 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3153 Configure option --with-openssl=<dir> now works when a directory is
3154 specified. Patch provided by Morten Bogeskov.
3156 New option for YAZ client, -u <auth>, that sets authentication.
3158 ZOOM fix: error information was sometimes "missing", since error
3159 was cleared/reset too when it shouldn't.
3161 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3163 --- 1.8.4 2002/01/04
3165 Scan for ZOOM API. New object ZOOM_scanset. New functions
3166 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3167 ZOOM_scanset_destroy.
3169 New ZOOM function, ZOOM_connection_last_event, that returns type
3170 of last event (such as "receive data", "send data", "apdu received",
3173 New ZOOM option, schema, that specifies schema for retrieval.
3175 New CCL feature. Qualifiers can be aliases for one or more
3176 other qualifiers (if more than one is given, OR is used).
3178 ZOOM uses named result sets if target supports it.
3180 Two new YAZ client commands: . (dot, which sources a script of YAZ
3181 client commands), and ! (to execute shell command.). Implemented
3184 Working on Debian packages.
3186 --- 1.8.3 2001/11/19
3188 YAZ client enables named result sets only if target supports it.
3190 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3192 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3193 with key="host" to get same result.
3195 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3196 Function Z3950_resultset_record(s) returns references to records
3197 "owned" by resultset. To become owner use Z3950_record_clone.
3199 Function z_ext_record handles Extended Services. Thanks to
3202 --- 1.8.2 2001/11/12
3204 CCL Parser fix: ignore token comma when dealing with and-lists.
3206 Documentation updates for COMSTACK.
3208 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3209 Changed prototype Z3950_records. For some functions, int parameters
3210 were changed to size_t.
3212 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3215 New MARC decode/display function, marc_display_exl, which properly rejects
3216 non-ISO2709 records. YAZ client uses it.
3218 --- 1.8.1 2001/10/29
3220 Fix bug: local attribute set wasn't set correctly in PQF strings.
3224 * Old Z39.50 codecs no longer supported.
3226 Added ZOOM C binding. See http://zoom.z3950.org/
3228 Renamed states for COMSTACKs to avoid confusion with events.
3230 Implemented cs_look and proper cs_rcvconnect.
3232 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3234 Configure detects POSIX threads on OpenBSD.
3236 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3237 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3239 When error is returned from present handler, non-surrogate diagnostic
3240 is returned in present response (and fetch handler is no longer called).
3242 * Minor adjustments to pquery parser (PQF). Token characters may be
3243 escaped by using backslash (C-style).
3245 PQF parser allows string attribute values to be specified. For @attr,
3246 non-numeric characters after the equal-sign are treated as strings
3247 (e.g. @attr 9=title).
3249 CCL trunction character may be defined (@truncation in file)
3251 * function zget_ExtendedServicesRequest sets waitAction to
3252 waitIfPossible (was wait).
3254 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3257 CCL operator names may be set in field definition files (CCL_bibset).
3258 See ccl/bib1 for an example.
3260 Fixes in ASN.1 compiler for C++ compatibility.
3262 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3263 and "op_or" to avoid conflict with C++.
3265 Fixed problem with GNU readline detection on Redhat 7.0.
3267 Added step-size for Scan backend handler.
3269 Fixed bug that made the frontend server crash when no attribute
3270 set was specified for scan.
3272 Front-end server automatically switches to original working directory
3273 when installed as an NT service. Previously -w had to be specified to
3276 Added extended attributes for retrieval module (data1), so that data1
3277 records carry d1_readXML/SGML attributes. d1_read also supports
3278 null-data rules ( <tag/>)
3280 On UNIX when POSIX threads are available, a separate library libyazthread
3281 is created. Programmers should link with that library and the yaz library
3282 when using threads. The reason for the split was that some applications
3283 on Linux, such as Apache, doesn't work well when using shared objects that
3286 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3287 (or any frontend server) in SSL mode by specifying ssl: followed by
3288 address. Only tested on UNIX.
3290 Added feature for CCL module. Virtual structure s=al or s=ol generates
3291 and-list and or-list respectively instead of phrase search.
3295 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3296 log_mask_str. This was done to avoid name conflicts with other libraries
3297 (such as other PHP extensions).
3299 Added raw OID member for preferred record syntax (request_format_raw)
3300 and returned record syntax (output_format_raw) for backend fetch method.
3302 Config file yaz-config now accepts options so that it returns specific
3303 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3305 Shared library support for UNIX using GNU libtool.
3307 * Modified backend interface. Request/Response struct's replaced by
3308 one read/write C struct. For example bend_fetchrequest and
3309 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3310 Every handler - even search has to be registered in bend_init
3311 handler. This means that the YAZ library no longer refers to
3312 external functions and it makes it possible to make the whole
3313 thing a single DLL/SO.
3315 Added Segment handler for backend server.
3317 Added Zmbol/Zebra administrative functions to YAZ client.
3319 Threaded frontend server on UNIX (when POSIX Threads are available).
3320 Starting the server with option -T enables multi-threading.
3324 Added configure option --enable-comp/disable-comp to control use
3325 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3326 located in sub directory asn.
3328 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3329 in ${exec_prefix}/bin along with the other programs yaz-client and
3332 GNU automake used to maintain makefiles.
3334 Added several OID's.
3336 Changed retrieval module so that we can load records with no abstract
3337 syntax defined. Tagpaths in these records are fully composed of string
3340 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3344 On UNIX, the generated makefile now supports a proper 'make install'.
3345 The prefix can be set via GNU configure to set the install location
3346 (default is /usr/local).
3348 * YAZ programs client and ztest were renamed to yaz-client and
3349 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3350 locations, such as /usr/bin,/usr/local/bin,etc.
3352 * YAZ Header files were moved from include to include/yaz. YAZ Header
3353 files are referred to as include <yaz/log.h> rather than <log.h>.
3354 The YAZ include path (-I ..) is therefore the same as before. Programmers
3355 should update their #include statements or use -Ipath/include/yaz
3356 instead. The main motivation for doing this change is that YAZ header files
3357 can be installed in "standard" locations /usr/include,/usr/local/include
3358 without introducing conflicts, since ALL YAZ header files are stored
3359 in subdirectory yaz (under /usr/include for example).
3361 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3362 rather than project/workspace files. We switched because project files
3363 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3366 Changed name of logging function, logf, to yaz_log, to prevent name
3367 clash with some math-log functions. The YAZ header log.h defines logf
3368 to yaz_log (#define) so there should be no incompatibilities by this
3371 Added bend_start/bend_stop handlers for server. These handler are
3372 called on start/stop of server. For windows they are called whenever
3373 a service is started/stopped.
3375 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3376 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3377 in util/yc.tcl. The auto-generated C code structures are, in a few
3378 cases, incompatible with the old decoders. There are differences in the
3379 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3380 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3381 The preprocessor variable ASN_COMPILED is defined when the compiled
3382 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3383 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3384 wish to use the old encoders/decoders you can specify --disable-yc
3387 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3388 version so that it supports both new - and old version of DB Update
3390 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3391 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3392 change. The name parameter can be set to 0 in which no name is specified
3393 for the construction. The macros odr_implicit and odr_explicit sets name
3394 parameter to zero for the construction involved. New macros
3395 odr_implicit_tag and odr_explicit_tag are similar to the others,
3396 except that a name parameter is added. For programmers' that don't use
3397 ODR they probably only need to change the call to z_APDU and z_External.
3399 Added access control facility by interfacing the TCP wrapper library.
3400 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3401 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3402 name of the daemon and enables the access control as specified in
3403 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3405 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3406 den Dool <H.M.vdnDool@kub.nl>.
3408 Added reference ID parameter to most functions in server API - refer
3409 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3411 Changed name of ccl library to libccl.a (was ccl.a).
3413 Fixed bug in decoder for Explain (Category TargetInfo).
3415 Added support for GNU readline in client. Thanks to Jacob Poulsen
3416 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3418 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3419 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3420 IMPLEMENTATION! This change was made to the development version before
3421 the ZIG decided to retract the amendment. If any users MUST be
3422 compatible with the original Update definition, PLEASE CONTACT US, and
3423 we will include a separate definition corresponding to the old Update
3424 ES. Note that because of the change to the ASN.1 of the
3425 TaskPackageRecordStructure we cannot define a single structure that
3426 will support both versions.
3428 * Added const modifier to buffer parameter for some ODR/BER encoding
3429 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3430 completeWAIS, odr_dumpBER.
3432 Fixed bug in client.c which caused a crash when a scanResponse didn't
3433 contain positionOfTerm.
3435 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3436 * will cause an error in a client if a non-YAZ target sends both a
3437 * list of Scan entries and non-surrogate diagnostics.
3439 Retrieval module enhancements. Tag sets may be typed in the reference
3440 to it. From the .abs-file the "tagset" directive takes a third optional
3441 integer type for the tag set referenced. From a .tag-file the "include"
3442 directive takes a third optional type as well. The old "type" directive
3443 in the tag set itself is still recognized but acts as the default type
3446 Backend interface change. Individual Scan terms returned from bend_scan
3447 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3448 in include/backend.h.
3450 Retrieval module enhancements. Multiple tag sets and attribute sets may
3451 be specified in abstract syntax specs. Revised the error/warning for
3452 logging messages reported by the retrieval module when reading the
3455 Object Identifier system (oid_..) changed. The API is backwards
3456 compatible but the oid-routines now allocates new OID's when needed.
3457 Raw OID's may be specified in oid_getvalbyname.
3459 YAZ now uses GNU configure to generate Makefile(s).
3461 * Minor changes in some of the member names of DeleteResultSetRequest and
3462 DeleteResultSetResponse. See include/proto.h.
3464 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3465 and added member 'languages' in TargetInfo (which was missing).
3467 Changed the way attribute sets are handled in the retrieval
3468 module. These are now cached, just like the abstract syntaxes
3471 Changed YAZ so that it links with compiled ASN.1.
3473 Added Explain-schema definitions and mapping routines. The following
3474 Explain categories have been implemented: AttributeDetails,
3475 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3477 Fixed minor bug in Windows version of Server Library.
3479 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3481 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3483 Added EXTERNAL: UNIverse Resource Report (non-standard).
3485 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3486 ENUMERATED and SET OF.
3488 * Added 'const' to some of the char pointer arguments for the
3489 functions, data1_read_node, data1_getelementbytagname,
3490 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3493 Fixed bug in data1_insert_taggeddata - the last_child member of
3494 parent wasn't initialised.
3496 * Changed data1_read_record and data1_read_node so that the supplied
3497 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3498 doesn't refer to any parts of the "SGML"-buffer.
3500 Fixed bug in server library (Windows version of statserv_remove).
3502 * Changed code so that it compiles as C++. The type definition
3503 of Odr_fun which is a member of Odr_arm was changed. The result is,
3504 that an explicit typecast is needed for the fun pointer when
3505 using Odr_arm - as in:
3506 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3508 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3510 Implemented the new structured date and time definition as approved
3511 by the ZIG. Added schemaId element to the specificTag in Espec-1
3512 (also approved at the last ZIG). Thanks to RVDM.
3514 Added some Object identifiers (RVDM).
3516 Changed the Update Extended Service (RVDM).
3518 Added command "refid" to client which specifies referenceId for
3519 the following requests.
3521 Implemented extended service handling for server. See ztest.c
3522 for an example as well as backend.h. New handlers are registerd
3523 in the Init handler.
3525 * Changed interface for sort in server.
3527 Added new members to statserv_options_block. It allows a server
3528 to read options from another source than just the command line. Thanks
3529 to Charles Woodfield.
3531 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3532 renamed to zboolean. Some C++ compilers complained about the name.
3534 Minor changes to gils.abs. Added index 's' (sort) on title
3535 and date/time-last-modified.
3537 --- 1.4pl2 1998/1/30
3539 Fixed bug in server library regarding inetd mode (-i). This bug
3540 was introduced by release 1.4.
3542 --- 1.4pl1 1998/1/29
3544 Added sort facility in client and backend server interface.
3546 Fixed problem with dependencies in Makefile(s).
3548 Fixed bugs for encoders/decoders of extended services and
3551 Implemented sub-tree feature for schemas. Sub-trees are
3552 referenced in *.abs-files. See explain.abs for an example
3553 of the use of this feature.
3555 Modified bib1.att; local attributes for ANY didn't include
3556 ANY itself (only affects use of the retrieval module).
3558 Fixed bug in plain SGML reader in function data1_read_node:
3559 tags with prefix "var" was incorrectly interpreted as variants.
3561 Added feature "sub-schemas" to enable references to - and definitions
3562 of - group of elements.
3564 * Removed member parent from type data1_element (in data1.h).
3566 Implemented function odr_nullval() that returns the value of
3569 * Removed member num_children from data1_node (in data1.h).
3571 Made NT service interface part of the server library. The
3572 function statserv_main uses the NT service when required and
3573 calls the statserv_start / statserv_close routines.
3575 Routine zget_SearchRequest and zget_PresentRequest fills
3576 resultSetName/Id member with "default" instead of "Default".
3578 Fixed memory leak in server. Request queue member wasn't freed.
3580 Fixed nmem_exit so that memory is freed.
3584 Revised the CCL parser utility to be thread safe.
3586 Added function, oid_ent_to_oid, to replace the function
3587 oid_getoidbyent, which is not thread safe.
3589 * Added nmem_init and nmem_exit to initialize and release
3590 NMEM resources. Function nmem_init should be called once in the
3591 initial thread before NMEM/ODR is used. statserv.c and client.c
3592 have been changed accordingly. The change was necessary to make
3593 NMEM thread safe. The NMEM memory pool is shared amongst threads
3594 in a process. Unix-based applications will still work fine without
3597 Added NT Services interface for the the Z39.50 (statserv) Server.
3598 Refer to the ztest.c source on the usage.
3600 Windows 95/NT port using MSVC5.0. Project files are included in the
3603 * Defined new 'global' handle for the retrieval (data1) system. The
3604 new handled, data1_handle, describes the state of the data1 system.
3605 This handle is passed as first argument to virtually all
3606 data1 related routines. The functions data1_create and data1_destroy
3607 creates and destroys a data1 handle respectively.
3609 Added ODR encode stream member to all backend request structures
3610 init, search, scan etc. This stream should be used to allocate all
3611 memory used for the response when thread safe operation is needed.
3613 Changed the comstack utility, cs_addstr, to be thread safe. The
3614 returned hostname string returned by the function is now part the
3617 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3618 function. The cs_straddr takes a COMSTACK handle as argument, so this
3619 function must be used after cs_create and before bind/connect.
3620 This function is thread safe.
3622 Moved test server to 'ztest' directory - generic server code still
3623 in 'server' directory.
3625 Made prefix query (pquery.c) utility thread safe.
3627 Added new function modifier YAZ_EXPORT to 'export' public DLL
3628 functions when using windows (see include/yconfig.h).
3630 Added definitions to the OID database (util/oid.c) (RVDM).
3632 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3634 Added call to ccl_rpn_delete in client program.
3636 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3637 release of RPN structure.
3639 Added support for C++, headers uses extern "C" for public definitions.
3640 With input from RVDM.
3642 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3643 Thanks to Ronald van der Meer (RVDM).
3645 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3647 Added support for private extensions to the OID database
3648 (oid_setprivateoids()). Thanks to RVDM.
3650 Added optional, physical ANY (key replication)
3652 Fixed null-reference problem in GRS-1 output filter.
3654 Proximity operator added to Prefix Query Format (PQF).
3656 In test client command "base" accepts multiple databases.
3658 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3662 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3664 Smallish bug-fixes in the new encoders/decoders (explain).
3666 Bug fixed in DeleteRequest.
3668 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3670 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3672 Added SOIF syntax (using private OID for now) to retrieval module and client.
3674 Added Update extended service.
3676 Added SearchResult-1 additional info structure.
3678 Added optional CCL (ISO8777) interpreter as separate module. Available
3681 --- 1.2 1996/6/10 (1st anniversary release)
3683 Added Summary record syntax. Lightly tested.
3685 Added OPAC record syntax. Untested.
3687 Added ResourceReport service encoders/decoders. Untested.
3689 Fixed bug in z_Unit - wrong tagging on unitSystem.
3691 Fixed bug in the DiagRecs decoder.
3693 Added options for max PDU size and session timeout to frontend-server.
3695 Added documentation of query-language parsers and other supporting utilities.
3697 [frontend-server] Added Attribute set to the bend_scanrequest API.
3699 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3700 surrogate diagnostics were generated.
3702 [retrieval] Allow multiple local values for attribute.
3704 [retrieval] Allow multiple attributes per element in .abs files. index type.
3706 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3708 --- 1.1pl2 1996/4/10
3710 Minor changes, mostly specific to Zebra's requirements (retrieval)
3714 Repaired bug in frontend server when running multiple listening
3715 endpoints in dynamic mode.
3717 z_External() now won't break if a known, ASN.1 value comes encapsulated
3718 in an octet-string. The value will pass through unmodified in an Odr_oct.
3720 Added a bit of code to the demo client to decode & display
3721 ASN.1-structured records represented in the octet-aligned branch of
3722 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3724 Added z_ext_getentbyref() to the ASN module. Doc updated.
3726 * Completed the SCAN definition in the ASN module. This may break SCAN
3727 code based on older YAZ-versions at compile-time. The fix is easy -
3730 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3731 under the SCAN definition. Remember to initialize this, server-people.
3733 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3734 that this does not extend to ODR and ASN.
3736 Comstack allows insertion of established socket (primarily for
3737 inetd-operation of servers). Doc updated.
3739 Front-end server can now start from the inetd in TCP mode. Doc
3742 --- 1.0pl4 1996/1/24
3746 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3747 the rank and record number.
3749 Adjustments to the frontend server.
3751 Fixed diagnostic BER dumper. It ignored the file argument.
3755 Various changes to retrieval module.
3757 Changed the union discriminators of the protocol files from enums to
3758 ints paired with #defines.
3760 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3763 *Changed operator in the RPN structure to 'roperator', again to avoid a
3766 Fixed problems in Explain decoders/encoders.
3768 --- 1.0pl2 1995/12/6
3770 Memory bug in log module fixed.
3772 --- 1.0pl1 1995/12/5
3774 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3776 Bug in Explain DatabaseInfo module fixed.
3778 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3782 The shift to v1.0 signals that we now consider the *core* functionality
3783 of YAZ reasonably stable (the core being more or less equivalent to
3784 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3785 tested (Explain not at all - though that will happen soonish).
3787 Minor changes to code to support Windows port.
3789 Various minor changes after we're getting to use GRS-1 & co. more.
3791 Added Espec-1 format.
3793 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3794 of the protocol and it cannot be selected when encoding (maps into 'string'
3795 when decoding). Needed to talk to some servers.
3797 Demo client can request simple element set names.
3799 Added Diagnostic Format encoders/decoders.
3801 Added simple Close handling to frontend server (no hooks for resource
3802 reporting yet), and demonstration client.
3804 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3806 --- 1.0b3 1995/08/24
3808 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3809 handled incorrectly when records were requested in the searchResponse. This
3810 will only affect you if you use the frontend-server.
3812 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3813 Test-client will ask for and print GRS1. Ztest will return dummy records
3816 Added Explain encoders/decoders to the service-level API. Untested.
3818 Added Extended Services: Item Order encoders and decoders to the Service-
3819 level API. Untested. We could use a recent copy of the pertinent bits
3820 of the ILL protocol to add those bits.
3822 Added diagnostic format 1 encoders/decoders to the service-level API.
3825 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3826 odr_cons.c, which causes a more correct output.
3828 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3829 was always set to 0 when no records were requested in the searchRequest.
3831 * Added better external-handling. This shouldn't harm old code that
3832 *encodes* externals. It can break code that looks for a
3833 'single-ASN1-type' representation, since those types that are known
3834 are now decoded immediately. Look at the SUTRS sample code in
3835 seshigh.c and client.c. Documentation updated.
3837 Handling of structured records in bend_fetchresponse. Length -1 marks
3838 structured record, type is deduced from format field.
3840 --- 1.0b2 1995/06/27
3841 Fairly quick maintenance release to add SUTRS support.
3843 Fixed handling of SUTRS records in the demonstration client.
3845 * Added format field to the bend_fetchrequest and bend_fetchresponce
3846 structures of the backend API (frontend server). When the record is
3847 returned, the value of the format field is mapped to an OID. The
3848 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3849 of the record. The special value VAL_NONE in the bend_request means
3850 that no specific format was requested by the client. Documentation
3851 updated accordingly. Test server (ztest) will return a fixed dummy
3852 SUTRS record if your client requests SUTRS.
3854 Documentation updated accordingly.
3856 You can now set external libraries and RANLIB support in the top-level
3860 First public release.
