3 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
4 The standalone ZOOM sort was completely broken since 5.0.13.
6 ZOOM: generate event Connect rather than None for partial connect
7 (in fact getaddrinfo resolving).
9 ZOOM: only supply clientIP for InitRequest. Rather than for all
12 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
14 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
15 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
16 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
18 New "Facets" section in the documentation.
22 Call exsltRegisterAll in yaz_init_globals, so that all applications
23 using YAZ will have EXSLT things enabled.
25 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
27 Update various URLs to the re-organized SRU pages at LoC.
31 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
34 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
35 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
36 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
41 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
45 Fix gcrypt not properly initialized YAZ-740.
49 Describe memcached option for ZOOM.
51 ZOOM: throw present request out of range again YAZ-739
52 Was removed in YAZ 5.0.13.
56 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
57 with localtime_r when threads + fork is used (such as Metaproxy).
59 yaz-config: quote some RHS values (that might include blanks)
61 zoomsh: shows SearchResult-1
63 zoomsh: sortby command
65 zoomsh: use proper list of connections and result sets YAZ-725
67 Avoid yaz_log in sigterm handler for GFS YAZ-737
68 Logging is still performed, but outside sig handler.
70 New ZOOM C feature: result-set caching with memcached. Example:
71 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
73 Remove SSL via OpenSSL support YAZ-732
74 Also deprecate two functions from comstack that aren't working with
75 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
77 Revert "Bison: use %name-prefix directive rather than -p option"
81 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
83 SRU GET/Solr base URLs may hold additional ?args YAZ-729
84 ZOOM option extraArgs already does this, though. It seems useful
85 when dealing with Solr targets to limit by filter, eg.
86 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
88 Remove #fragment for HTTP request encoding YAZ-730
90 Doc: Update list of DLLs/LIBs
92 Doc: update href link to Unix utils and Git.
96 ZOOM: fix "lost connection" problem with servers that uses both squid
97 and another proxy behind it that returns Location headers with relative
100 zoomsh: do not use readline for stdin (no tty) YAZ-724
101 Just use fgets in that case. If the user hits Ctrl-D a new-line
104 zoomsh: empty command ignored YAZ-723
105 rather than performing exit of zoomsh.
107 yaz-url utility offers option -v to enable verbose mode.
109 yaz_url uses yaz_check_location and offers verbose mode.
111 Add new function yaz_check_location.
112 This function gets an absolute URI from Location (HTTP redirect).
114 cookie API: introduce yaz_cookies_reset
116 Update cql.y for newer bison YAZ-720
117 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
118 longer supported. Instead one must use %lex-param and %parse-param .
120 --- 5.0.10 2014/01/09
122 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
125 rpn2solr: support truncation left(2), left&right(3) YAZ-718
127 Mention SRU version 2.0 in yaz-client man page.
131 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
136 Make cs_parse_host public.A
138 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
139 introduced in YAZ 5.0.6.
143 Fix buffer corruption for yaz-ztest record fetch.
147 Allow yaz-ztest to return user-defined records (one record per file).
148 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
150 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
151 Use the stream write instead of odr_printf which has a 4K tmp buffer.
153 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
157 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
158 can read and write this format. For record format JSON, yaz-ztest returns
159 MARC-in-JSON records.
161 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
162 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
166 Improve error reporting for ICU chains YAZ-707
167 Report config element+rule when ICU status is "failure".
169 ZOOM: stop fetching if present response has no records YAZ-710
170 Some targets return less records than their hit count would suggest.
171 This prevents ZOOM from continuing to fetch records if any present
172 response has 0 records in the response.
174 Ensure that GFS calls exit if any listener fails YAZ-710
175 Before, if XML config was in use, it would start the default
180 yaz-ztest: -V shows version (like yaz-client -V)
182 New iconv encoding: danmarc YAZ-692
184 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
186 daemon: only wait for immediate child rather than all children. YAZ-704
188 yaz-client: fix setting of SRU record schema. If scheme was unset, it
189 could lead to invalid memory reference.
193 yaz-ztest returns schema for MARCXML test records. SRU require that
194 recordSchema for records.
196 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
197 instead of non-surrogate diagnostic. This is a per-record failure.
199 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
200 may refer to multiple listeners now. Attribute listenref is a comma separated
203 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
204 option is given for GFS, the dirname of filename (for -f) is used
205 as prefix for options such as cql2rpn, ccl2rpn, etc.
207 Content-Type charset fixes YAZ-701 . Do not inspect charset in
208 Content-Type header for SOAP when decoding SRU. The payload (XML)
209 itself tells what encoding it is. In response, never supply encoding
210 in Content-Type. The response payload (XML) tells what it is (with no
211 encoding in XML it's UTF-8).
213 HTTP decoding: allow blanks in URL paths YAZ-700
217 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
218 and facets. Ensure recordData and recordSchema are always present in
219 record element, because they are required.
221 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
224 Simplify in a lot of places using odr_strdupn.
226 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
230 Increase various buffers in GFS's statserv_options_block
231 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
232 This change makes many type-casts redundant, and, thus simplifies code.
234 Remove last bits of WAIS support.
236 Remove member 'size' from Odr_oct.
238 Slim down the public part of 'struct odr'. Most elements are not part
239 of struct Odr_private.
241 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
242 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
243 In particular facets are supported in both client - and server side.
244 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
245 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
246 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
247 both request/response). This is what a search handler in the GFS
248 will see (regardless of whether operating in SRU mode or Z39.50).
250 Changes to the srw.h (SRU/Solr) definitions include:
251 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
252 (char*), which replace union query and query_type (int). This is because
253 SRU 2.0 supports a queryType parameter. This also means that, to carry
254 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
255 x-pquery=PQFstring (extention parameter). The extension parameter
257 - New element, packing, that has information about SRU
258 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
260 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
262 New element, packing, in Z_SRW_explainRequest.
264 New elements in Z_SRW_scanRequest, queryType and scanClause.
265 These replace query_type and scanClase untion. This is similar to what
268 --- 4.2.69 2013/10/01
270 GFS: log when closing down - at least SIGTERM YAZ-684
271 Also change formatting WRT PID logging a bit.
273 Improve display of MARC records with multi-byte subfield IDs YAZ-695
274 In some rare cases subfield identifiers are multi-byte characters.
275 This will try to deterime length of those and split accordingly.
276 This affects display in line mode as MARCXML/MarcXchange. The encoding
277 of ISO2709 is the same.
279 Change inp argument to const for yaz_read_UTF8_char.
281 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
283 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
285 Better check of marc leader info YAZ-691
286 Problem is that some systems generate MARCXML/MarcXchange with
287 funny headers. These will not work if encoded as ISO2709.
288 Some tests produce new output, due to updated warning messages
290 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
292 yaz-client: display MAB records YAZ-689.
293 Thanks for Heiko Jansen for this patch.
295 New utility z_get_HTTP_Response_server which allows both HTTP server name
296 and HTTP server URL to be given in response.
298 Debian: do not depend on obs tcl8.3.
300 Debian: do not depend on obs libicu36-dev.
302 --- 4.2.68 2013/09/23
304 GFS: pass additionalSearchInfo to search memeber search_input if
305 given. Otherwise pass otherInfo. Request for facets and other search
306 related things will be passed there in future versions of YAZ.
308 New ZOOM setting, authenticationMode, which allows authentication
309 paramters to be encoded in the URL rather than via HTTP Basic auth.
312 rpn2solr: fix nested AND/OR handling. YAZ-685
314 Add comparison routines for some Z-types, such as NamePlusRecord,
315 RPNQuery, Query, RecordComposition and OtherInformation.
317 --- 4.2.67 2013/09/19
319 Don't decode MAB as MARC. Just like we don't attempt to decode
320 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
322 CCL: allow quoted terms for date ranges. YAZ-681
324 Introduce ccl_parser_qual_search. This function makes old function
325 ccl_qual_search, from YAZ 2, available again.
327 Add yaz_facet_list_to_wrbuf. YAZ-683
329 --- 4.2.66 2013/09/11
331 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
332 schema was given for search. YAZ-675
334 Add Solr date range searches. YAZ-621
336 --- 4.2.65 2013/08/22
338 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
340 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
342 ISO2709/MARC parse most octet aligned records; not just those that
343 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
344 MARC parse more records instead of just dumping as is. YAZ-670
346 ZOOM: proper caching for variations of record schema. YAZ-671
348 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
350 --- 4.2.63 2013/07/17
354 --- 4.2.62 2013/07/11
356 New utility z_get_HTTP_Response_details - an extended version of
359 New utility yaz_url_get_error which returns error message of last
360 failed yaz_url_exec call.
362 yaz-url and url functions: allow max HTTP redirects to be controlled.
364 New functions yaz_file_glob2, yaz_xml_include_glob.
365 These functions takes a flags parameter, which, for now only controls
366 whether to fail inclusion of a non-existing file (without glob
367 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
369 --- 4.2.61 2013/06/20
371 For MARC XML parsing, allow record without leader. A fake/default leader
372 is inserted and a warning is tagged with the record.
374 ICU: fix leak in in icu_iter_get_org_info.
376 --- 4.2.60 2013/06/14
378 ICU: fix bug in icu_iter_get_org_info (un-init variable).
380 --- 4.2.59 2013/06/11
382 Implement z_HTTP_header_remove.
384 --- 4.2.58 2013/06/11
386 ICU: Disallow 0 ptrs for some ICU string utilities.
388 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
389 returns original tokens (before normalization).
391 CCL: avoid z39.58/regex truncation when not needed. Apply only the
392 conversion of those masks, when absolutely necessary.
394 CCL: configurable masking character - @mask. Default masking character
397 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
398 full response anyway, so a Transfer-Encoding header will obstruct the
401 --- 4.2.57 2013/05/15
403 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
404 picking a socket. Problem is that some systems has IPV6 support, but
405 we can't create sockets for them, so we pick AF_UNSPEC first.
407 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
408 use content_len to determine resulting Content-Length in HTTP response
409 and NOT Content-Length supplied in headers by user.
411 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
412 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
414 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
417 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
418 with big endian and unsigned char (by default).
420 --- 4.2.56 2013/04/26
422 Fix yaz-client connect (crash in 4.2.55).
424 --- 4.2.55 2013/04/26
426 Fix proxy/host problem for ZOOM that could occur if unix sockets
429 New Debian package libyaz4-dbg.
431 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
432 differently in tcpip_close.
434 --- 4.2.54 2013/04/17
436 Windows installer of YAZ includes YAZ4J as a component.
438 CQL: allow "extra terms" again, by default. Thus, the CQL parser
439 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
440 and earlier. CQL parser may operate in strict mode where queries
441 not conforming to the standard BNF are rejected (syntax error).
442 Whether the CQL parser operates in strict mode is controlled with
443 cql_parser_strict . Strict mode enabled with option -S for utilities
444 cql2pqf and cql2xcql .
446 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
448 --- 4.2.53 2013/04/10
450 New charset, MARC-8c, which is like MARC-8 but allows control characters
451 0x01 through 0x1F, except ESC to be passed through verbatim.
453 Fix a problem with duplicate sub field character in MARC output. Problem
454 happened only when output was MARC-8 encoded.
456 --- 4.2.52 2013/04/03
458 yaz-ztest: Use hash for fake hit count. Before, random number was used.
459 This is problematic for unit tests using yaz-ztest. This patch also makes
460 a hash for CQL queries. For RPN, any term with a leading digit will be
461 treated as pseudu hit count (to force any particular hit count by a client).
463 yaz-ztest: return unique MARC dummy records. Beyond record offset
464 24, the author surname is patched with offset to make all records
467 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
468 on system wide default (/proc/sys/net/ipv6/bindv6only).
469 @4 binds to IPV4 only. @6 binds to IPV6 only.
471 Update CQL API documentation a bit
473 CQL: don't accept extra terms for queries. Makes the CQL parser
474 stricly conformant to the standard.
476 --- 4.2.51 2013/02/12
478 GFS: scan handler gets extra_args from request and may return extra
479 response data . That's for SRU only.
481 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
483 --- 4.2.50 2013/01/30
485 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
487 OPACXML: sync spelling of availabilityDate in XML to that of Schema
488 opaxxml.xsd. The schema had the correct spelling of this member always.
489 The ASN.1 was mis-spelled and still is (API change) - we are
490 not changing this. However, the OPAC to XML conversion had yet
493 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
496 New function, z_ext_record_oid_nmem, which is similar to
497 z_ext_record_oid but takes NMEM rather than ODR
499 --- 4.2.49 2013/01/18
501 ICU: New conversion element 'join' which joins tokens into one
502 with a custom character given by rule attribute.
504 --- 4.2.48 2013/01/10
506 New GFS search member: present_number. This is a hint to the
507 search handler how many records are going to be fetched immediately
508 following search. There's no guarantee that it's going to be the case,
509 since it depends on hit count (for Z39.50 piggyback) and whether errors
512 Make a few functions static (private). The functions getbyte_stream,
513 ungetbyte_stream and yaz_gets are now private. They were never declared
516 yaz-marcdump: exit(5) for serious decoding errors
518 ISO2709 decoding: be more picky WRT header
520 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
521 was only used as to indicate that next-result-set-position should be
523 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
524 Based on patch from Ashley Sanders.
526 Make some functions static/private in PQF parsing. Those functions were
527 never declared in a public header and so should not be in use by
528 applications based on YAZ.
530 --- 4.2.47 2012/11/23
532 ZOOM: special options to control APDU logging.
533 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
534 logging of APDUs until "saveAPDU" option is set again. If logging is
535 already enabled the effect is that current APDU buffer is cleared.
536 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
537 logging (default behavior on new connection).
538 The APDUs sent/received can be obtained by using
539 Using ZOOM_connection_option_get(c, "APDU") or
540 ZOOM_connection_option_getl(c, "APDU", &l).
542 GFS: relay implementation_version from backend
543 From 3.0.40 and later, implementation_version from backend was
544 not used in init response at all.
546 --- 4.2.46 2012/11/15
548 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
549 mode at all. Probably never did.
551 Make a new version of ztest.pem that, at least, is not expired.
553 --- 4.2.45 2012/11/13
555 Fix description of CCL directive 'case'.
557 More tight checking of form arguments (yaz_uri_to_array). Makes
558 YAZ better at rejecting big and/or bad POSTs.
560 SRU decoding does not report more than up to 10 invalid arguments.
562 rpn2cql: less quotes in generated terms. Semantics unchanged, but
563 it's prettier this way.
565 --- 4.2.44 2012/10/25
567 New utility yaz_decode_init_diag. Defined in proto.h.
569 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
570 given for unix local socket.
571 The COMSTACK string for doing so is:
574 unix:/myfile:tcp:localhost:9999/mybase
575 unix:/myfile:localhost:9999/mybase
576 unix:/myfile:http://fakehost/mybase
578 debian: Use dpkg-buildflags in build process.
580 --- 4.2.43 2012/10/19
582 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
583 global's SRU service uses a recordPosition scheme starting from zero.
584 First record's position should be one
585 according to the standard.
587 --- 4.2.42 2012/10/18
589 Allow more namespaces for SRU. This is to allow, for example, an
590 incorrect namespace returned from server
591 http://services.igi-global.com/sru .
593 Minor fixes for compilation on Windows.
595 --- 4.2.41 2012/10/11
597 daemon: log total number of bad signals from child on stop so that it
598 is more easy to spot problems with child worker processes.
600 retrieval: empty backend name attribute omits element set
601 from being used in retrieval.
603 --- 4.2.40 2012/10/04
605 Implement Solr sort strategy "solr", similar to sru11 sorting.
606 This will implement the correct parameters on Solr requst to do
609 --- 4.2.39 2012/09/28
611 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
614 MARC: Extra/missing indicator handled for MARCXML.
615 The indicator length is given in header and is the same for the
616 whole record. If attributes ind1, ind2 are missing, then content
617 character defaults to blank. Extra indicator attributes (beyond)
618 indicator length are treated as an error.
620 Reformat: delete trailing whitespace
622 --- 4.2.38 2012/09/17
624 MARC: fix non-ASCII characters for leader. This is to ensure we can
625 generate XML in UTF-8.
627 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
628 in one node with structure word.
630 --- 4.2.37 2012/09/04
632 yaz-json-parse: JSON output may be pretty printed by using option
635 Increase default value of max message for Z39.50 Init for GFS, ZOOM
636 and yaz-client. Old value was 1 MB. New value is 64 MB.
638 --- 4.2.36 2012/08/22
640 yaz-client: don't display bogus records from SRU servers. Some SRU servers
641 return more records than given by *maximumRecords*. Skipping those in
644 record_render: simplify buffer return handling and fix at least one bad
645 memory reference, that broke the test_embed_record sometimes.
647 Allow http://user:pass@host notation for yaz_url_exec.
649 zoomsh: allow shell command to be executed. Via the system(3) call.
651 yaz_poll: Allow num_fds == 0
653 yaz-client: fix bad encoding of "itemorder item". The itemorder
654 item <no> - command forgot to use length of encoded Item Request
655 package. Error present since YAZ 3.
657 yaz-ztest: fix bad usage of session handle. Bug was introduced when
658 result sets were saved (271a9c83).
660 SRU recordPacking: guess record packing in response rather than looking
661 at the recordPacking element which, OF COURSE, changed semantics in SRU
664 Decode SRU 2.0 responses. The official namespace for responses, according
665 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
666 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
667 nature.com's server, however, usee namespace
668 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
669 we are now using a glob-expr to match up the namespace. ZOOM C and
670 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
671 I can not find a single real example showing the "real" namespace in
672 the documentation from OASIS. The namespace for requests is different
673 from responses, but this is not added to YAZ yet, when we don't encode
676 --- 4.2.35 2012/06/26
678 zoom/record_render: add support for Base64 decoding fo MARC records
679 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
680 which will decode base64 + ISO2709 marc-8 encoded material from text node
683 --- 4.2.34 2012/06/07
685 Add missing definitions ZOOM_resultset_get_facet_field_by_index
686 and ZOOM_resultset_facets_names.
688 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
691 Change APDU dump printing to avoid long leading blanks. For levels 16
692 or larger the level is shown and the indentation is truncated but
693 recursed with modula 8. This makes it still reasonable easy to read
694 - even for nested BER dumps.
696 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
697 return 0 (incomplete package) in case where the BER package was
698 considered too nested (return value of -2).
700 dumpber: lines of level 15 are not indented further. Two spaces per
701 indentation; indentation 15 or more is indented to a fixed indentation
702 and augmented with a level=<no> indication.
704 zoomsh: increase max size of command+args
706 GFS: No limit in RPN buf size in CQL to RPN conversion.
708 --- 4.2.33 2012/05/09
710 New function for daemon utility, yaz_daemon_stop .
712 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
714 --- 4.2.32 2012/04/25
716 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
717 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
719 --- 4.2.31 2012/04/23
721 YAZ daemon utility relays SIGUSR1 to child process.
723 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
724 would result in en empty database list - which in turn would result in
725 encoding failure for search.
727 Fix reading beyond string in yaz_sort_spec.
729 --- 4.2.30 2012/04/11
731 Add two new SRU diagnostics:
732 236: Access to specified database denied
733 1015: Init/AC: Maximum number of simultaneous sessions for Userid
735 Document the very useful ZOOM-C option "apdulog".
737 CQL to RPN: term may be passed through verbatim. This is enabled with
738 truncation.cql . The assumption being that the term is already CQL.
740 --- 4.2.29 2012/03/20
742 record_conv: leader spec may be given for marc element.
743 The leader spec is given as attribute leaderspec for element marc.
744 For example to convert a MARC21 record from MARC-8 to UTF-8:
745 <marc inputformat="marc" outputformat="marc"
746 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
748 record_conv: allow user-XSLT params. For example:
749 <xslt stylesheet="MARC21slim2DC.xsl">
750 <param name="myparameter" value="myvalue"/>
751 <param name="otherparameter" value="othervalue"/>
754 record_conv: fix error handling for missing marc charsets.
756 CQL: fix extra terms in wrong order.
758 --- 4.2.28 2012/03/06
760 record_conv: modify new API for conversion types. The conversion types
761 may be passed in new functions yaz_record_conv_configure_t and
762 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
764 Avoid mixed statement/variable declare; fixes compilation with Visual
767 --- 4.2.27 2012/02/28
769 Add non-standard SRU diagnostic: 235: "Database does not exist".
770 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
771 Update SRU to Bib-1 diagnostic maps accordingly.
773 CCL: add two new diagnostics for unsupported masking. The new
774 diagnostics are: "Embedded truncation not supported" and
775 "Single charcacter mask not supported".
777 --- 4.2.26 2012/02/23
779 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
781 --- 4.2.25 2012/01/11
783 Build YAZ for Ubuntu Oneiric.
785 CCL: allow parantheses for proximity operands. For example CCL query
786 (a) % (b) is now allowed.
788 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
789 marked dead, rather then being destroyed. If not, the session memory is
790 being free'd before the search/scan handler is finished. Also destroy
791 'request' memory in request_release rather than in various places,
792 which resulted in leaks from time to time.
794 --- 4.2.24 2011/12/21
796 cql_sortby_to_sortkeys: honor sort prefix.
798 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
799 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
800 The rpn2cql family of functions now always returns quoted CQL terms.
802 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
804 --- 4.2.23 2011/12/15
806 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
807 sequence is treated as one. For example, &&a=b&&&c& is identical to
810 --- 4.2.22 2011/12/05
812 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
813 APDUs for a connection to a WRBUF.
815 --- 4.2.21 2011/11/23
817 Fix cql_sortby_to_sortkeys. Completely broken before.
819 Make CCL's @truncation work again.
821 --- 4.2.20 2011/11/09
823 New ZOOM connection setting: tproxy. It's like proxy, but does not
824 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
825 to set resolved address + port for a connection outside ZOOM itself.
827 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
829 --- 4.2.19 2011/11/07
831 Fix uninitialized variable in Solr spell support (could cause SEGV
832 for SRU response decoding).
834 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
835 back-end's addinfo through into the ZOOM response addinfo.
837 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
838 they are separated by a colon and a space rather than simply
841 --- 4.2.18 2011/10/28
843 Add support for Solr spell-checking/suggestions through ZOOM.
844 If a Solr target has been configured correctly for spelling-checking
845 and suggestions, these will now be returned on the ResultSet option
846 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
848 --- 4.2.17 2011/09/28
850 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
851 with a flag whether to substitute escape sequences or not.
853 --- 4.2.16 2011/09/22
855 Fix nmem_strsplit_escape to substitute escape char properly.
857 New option for zoomsh -e , which makes it abort on first error and
858 return process exit code to indicate success/failure.
860 YAZ options utility supports special option -- which makes all it treat
861 all following arguments as non-options.
863 --- 4.2.15 2011/09/16
865 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
866 searched if absolute filename is given.
868 Fix conv_xslt() error-reporting when stylesheet is not found.
869 (The value of fullpath is meaningless in this situation.)
871 --- 4.2.14 2011/09/07
873 Fix problem in CQL sort node creation: un-initialized memory.
875 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
876 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
877 CQL sortby depending on whether Type-1 or CQL is actually sent to the
880 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
881 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
883 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
884 will make it possible to use both single-character mask (#) and wildcard (?)
885 in CCL . Throw diagnostic for left truncation because that is not supported
888 --- 4.2.13 2011/09/01
890 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
891 cases using escapes (\-sequences) and masking.
893 PQF parse fix: A trailing backslash followed by end-of-string (\0)
894 would result in a read one byte beyond string.
896 rpn2ccl may use Z39.50 masking for terms (t=z).
898 ICU check fix. Don't include library -lCrun on Solaris, unless present.
900 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
901 not --cppflags (which seeems like an error in icu-config).
903 --- 4.2.12 2011/08/27 RPM package only
905 cql2ccl: fix conversion of terms: operator characters were not
908 --- 4.2.11 2011/08/25 RPM package only
910 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
911 CCL parser will map both # and ? to their regular expression
912 quivalents (. and .*).
914 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
915 of reserved CQL characters.
917 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
918 is, so that they are passed through.
920 --- 4.2.10 2011/08/24
922 ZOOM SRU mode: more aggressive re-connect.
924 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
925 made available as a utility function, declared in <yaz/logrpn.h>
927 rpn2cql_structure() supports proximity nodes (except that the Type-1
928 proximity node's "exclusion" binary is ignored, as there is no way to
929 express that in CQL). Fixes bug #4564.
933 Fix SEGV that could occur if set command of zoomsh was given without
934 value (2nd argument).
936 Fix SEGV that could occur if unsupported transport was given for
937 COMSTACK - say https (when SSL was unavailable).
939 Build yaz-url on Windows too.
943 New utility to get web content. Header is url.h. A command line tool
944 yaz-url is part of the distribution and packages.
946 Fixes for SSL COMSTACK (when gnutls is in use).
948 New functions yaz_base64{encode,decode}. Header is base64.h.
952 ZOOM C includes HTTP response buffer as additional info if it fails
953 to decode the SRU response.
955 Make wrbuf_json_puts available.
959 zoom: throw diagnostic for invalid value for option "sru". Before a
960 bad SRU request was sent.
962 Adding new utility wrbuf_vp_puts.
964 Add cclxmlconfig.obj to win/makefile. It was missing completely.
968 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
969 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
970 redirect was used at the same time.
972 MARC line mode decoding: be less picky about length given - first
973 5 digits of header that is.
975 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
977 Changes to decoding of SRU records: a record with recordPacking=xml is
978 modified with a new root element <yaz_record> if the recordData contains
979 multiple children elements. This is to make the record XML parseable
982 RPN to Solr conversion: encode special characters.
984 Generic Frontend Server: fix uinitialized member, stepSize.
988 Fix a bug in SRU decoding of records.. The database records stored
989 had un-initialized memory, but it would only be seen with yaz_record_render
990 and type_spec="ext" .
992 Fix a bug in ccl_qual_dup introduced in 4.2.3.
996 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1000 Add new utilities to convert from CQL to CCL . These utilities have
1001 prefix cql_to_ccl defined in cql.h.
1003 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1004 lead to memory heap corruptions when ICU utilities were in use.
1006 --- 4.2.1 2011/06/07
1008 Make compilation work without Libxml2.
1010 yaz-client: remove redundant blanks in display of searchResult-1 term
1013 --- 4.2.0 2011/05/18
1015 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1016 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1018 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1019 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1020 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1021 Note that the CQL sortby spec is only converted when the GFS is already
1022 converting from CQL to RPN (cql2rpn element).
1024 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1025 specify whether to collapse delimitors or not. The existing nmem_strsplit
1026 do collapse (collapse parameter = 1).
1028 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1030 Rename internal func yaz_use_attribute_create. While non-static, this
1031 function is not declared in a public header.
1033 --- 4.1.7 2011/03/15
1035 Add -lCrun when linking with ICU on Solaris.
1037 More quicks character set conversions for OPAC records.
1039 --- 4.1.6 2011/03/10
1041 fix problem with record_render: records were converted (character set
1042 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1044 --- 4.1.5 2011/03/08
1046 SRU: add methods for handling DADS SRU-proxy facets.
1048 Separate OPAC record character set for ZOOM_record. yaz_record_render
1049 allows a character set given as charset=from/opacfrom,to where 'from' is
1050 the character set of a bibliographic record, 'opacfrom' is character set
1051 of OPAC record and 'to' is the target character set.
1053 --- 4.1.4 2011/02/21
1055 yaz-client: show may XML format records. Command show followed by 'format'
1056 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1059 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1062 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1064 --- 4.1.3 2011/01/27
1065 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1067 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1068 this package can be distinguished from other vendors.
1070 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1071 as determined by configure
1073 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1075 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1076 returns no error and no record, the present request is considered
1077 partial (only a subset of the records could be returned by backend), and
1078 so it is appropriate to set Present Status to partial-4.
1080 --- 4.1.2 2010/11/02
1082 Move yaz-config man pages to section 1.
1084 More documentation about Solr.
1086 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1087 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1088 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1089 peers on some Linux systems. However, in general that does not work
1090 so YAZ can not rely on that to work. Debian changed behavior in this
1091 respect from Debian lenny to Debian squeeze (still testing as of Oct
1093 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1095 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1097 --- 4.1.1 2010/10/05
1099 Fix yaz-config output: echo_source not set correctly by configure.
1101 --- 4.1.0 2010/10/05
1103 Solr Web Service support for yaz-client and ZOOM.
1105 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1107 --- 4.0.12 2010/08/17
1109 Z39.50 facet support. Facet specifications are passed for search in
1110 other-information with ASN.1 as defined in facet.asn and OID
1111 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1112 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1113 3 is limit (number of entries to get in response). yaz-ztest returns
1114 dummy facets if a client asks for them.
1116 --- 4.0.11 2010/07/09
1118 CCL fixes: bug 2895 and bug 3539.
1120 GR1-display: add comma in display - was removed by mistake in
1123 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1125 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1127 --- 4.0.10 2010/06/18
1129 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1130 result set from a connection. The result set will be on its own
1131 thereafter; no operations on it will perform retrievals from a target.
1132 Only cached copies are returned.
1134 ZOOM C:fix case for HTTP servers responding with Connection:close.
1135 Ensure that if there is a current task it is resumed (like fetching
1136 more records in a result set) . Bug #3484.
1138 PQF parser: use odr_atoi for Odr_int (not atoi)
1140 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1141 values that contain any non-digits are treated as string attributes
1142 (previously decoding only checked for leading character ([0-9]). PQF
1143 encoding: attribute string values are not surrounded by double-quotes.
1145 --- 4.0.9 2010/05/21
1147 New utility for managing threads - thread_create.h.
1149 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1150 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1151 but YAZ' implementation do.
1153 Fixes for yaz_cond-functions on Windows 7.
1155 DLL export more symbols.
1157 zoomsh: show record do NOT render opac.
1159 Remove *.la files from Debian and RPM packages.
1161 --- 4.0.8 2010/05/11
1163 Debian package libyaz-dev depends on libgnutls-dev again (was
1164 removed in YAZ 4.0.6, but due to Libtool it is still needed
1165 even though yaz-config do not list libgnutls libs).
1167 ZOOM: Use only one WRBUF for returning string results for
1168 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1170 ZOOM: ZOOM_connection do not use a shared pointer to
1171 ZOOM_resultset after ZOOM_resultset is destructed by
1172 user. Reverts to YAZ 4.0.4 behavior.
1174 --- 4.0.7 2010/05/04
1176 record-conv: fix problem with at least one XSL conversion -
1177 due to probably incorrect usage of XML XSL documents.
1179 --- 4.0.6 2010/04/29
1181 Fix yaz-config for static mode and the use of SSL (gnutls).
1183 --- 4.0.5 2010/04/29
1185 Forward decl timeval struct in mutex.h and gettimeofday.h.
1187 yaz-config: fix 'static' mode linking.
1189 --- 4.0.4 2010/04/28
1191 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1192 are wrappers for pthreads or Windows. For Windows these are put in
1193 a separate DLL: yaz_cond4.
1195 libyaz.la (whole source) is compiled with thread. If thread support
1196 is enabled enabled, all source of YAZ is compiled with treading support.
1197 This allows core utilities such as yaz_log to use thread facilities.
1198 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1199 thread utilities. This commit moves mutex utilities (mutex.c) from
1200 libyaz_server.la to libyaz.la.
1202 yaz-json-parse displays leading text until error.
1204 --- 4.0.3 2010/04/09
1206 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1207 patch from Giannis Kosmas.
1209 SRU: no longer URL encode SRU database. The URL for an SRU server is
1210 a URL and such is alreeady encoded - at least when given with leading
1211 http:// or https://. This reverts behavior to YAZ 3.0.50.
1213 Support for new MARC XML notation TurboMARC which like MARCXML is a
1214 complete representation of MARC/ISO2709.. This one, however, is more
1215 compact and allows for faster processing with XSLT. TurboMARC can be
1216 used in the marcdisp.h API, from the yaz-marcdump utility and from
1219 yaz-ztest can be configured - via the database - to perform certain
1220 delays when it performs operations search, present and single record
1221 fetch. This allows testers to make yaz-ztest act as a real or even slow
1222 Z39.50 server. Refer to the yaz-ztest man pages for details.
1224 --- 4.0.2 2010/03/09
1226 wrbuf_destroy allows NULL WRBUF passed to it.
1228 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1230 Add ZOOM_connection_close.
1232 No fixed size buffers for ZOOM shell - bug #3257.
1234 tstodr: make it work on s390 platform.
1236 New icu iterator-functions. The new icu_iter-functions makes it possible
1237 to use ICU chains from many threads.
1239 yaz-client: better syntax check for show command.
1241 --- 4.0.1 2010/01/26
1243 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1246 New simple local-file XML include facility which allows file glob-patterns.
1247 Refer to yaz/xml_include.h.
1249 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1252 ZOOM_record_get supports new parameter "format" which makes it format XML
1255 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1256 JSONText in ECMA-262) is JSONValue, not JSONObject.
1258 --- 4.0.0 2010/01/20
1260 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1261 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1263 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1264 POSIX/Unix builds .so with major version 4.
1266 Remove old LOG_-defines from log.h. They have been obsolete and
1267 undefined by default for the last 5 years.
1269 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1271 GFS: Remove socket (int *fd) from search_rr handler. The socket
1272 descriptor ptr is a facility that allowed a search handler to supply
1273 a socket which would serve as a callback - when search was complete.
1274 This facility has now been in use for years.
1276 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1277 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1278 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1279 returns 'const char *' rather than 'char *. The returned string is
1280 read-only and should not be modified by applications. COMSTACK cs_close is
1281 now a void function - it no longer returns int. No applications check for
1282 the value and the implementations has always returned 0.
1284 ZOOM: use size_t for scan hit counts and str size. Functions
1285 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1286 occ (hit count) and len (string length) are now of type size_t pointer
1287 rather than int pointer. This is to be able to represent large hit counts
1288 and to also just to use the proper type for string length (strlen result).
1290 New JSON parser. Refer to include/yaz/json.h .
1292 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1293 Used to be int in some cases. Many wrbuf_-functions used to return an int
1294 indicating some length.. These return values were never used. And so they
1297 ODR: odr_malloc, odr_total now takes size_t for size.
1299 clone_z_type: fix leak; occurred for encoding failures.
1301 --- 3.0.52 2009/12/03
1303 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1304 bug was introduced in 3.0.51.
1306 --- 3.0.51 2009/12/02
1308 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1310 tcpip comstack: fix leak for getaddrinfo.
1312 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1313 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1314 Decoding of SRU "path" database is performed by private function
1315 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1316 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1318 yaz-client: honor base command for SRU. Change when database setting
1319 is applied for SRU and ensure it is kept when a connection is reset.
1320 Change also the way errors are displayed or SRU (decoding of packages).
1322 --- 3.0.50 2009/11/02
1324 Add support for extra request / response data for SRU codecs and GFS.
1325 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1326 for extra data response buffer and length. For the GFS, both request
1327 and response data (XML) is carried in extra_args and extra_response_data
1328 for the search handler. Patch by Ko van der Sloot.
1330 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1331 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1332 10010). This fixes bug #2113.
1334 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1335 cmdfile included a 'quit' command that would result in a memory violation.
1337 --- 3.0.49 2009/10/01
1339 Make a number of functions defined in xmlquery.c static. These have
1340 never been declared in a public header file (yaz/xmlquery.h) and was
1341 made public by mistake.
1343 Improve speed of character conversions (iconv utilities). This makes
1344 conversions from MARC-8 faster.
1346 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1347 unless type desired is "raw". This will prevent type "xml" from
1348 returning ISO2709 .. Which obviously can not be XML parsed.
1350 Fix memory leak in ZOOM that would occur if option apdulog was used
1351 on a re-used connection.
1353 Frontend server logs HTTP requests.
1355 Frontend server now sends Z39.50 close when it times out (sesssion has
1356 been idle for too long). Versions 2.0.30 and earlier also sent close.
1357 But due to a mistake this was disabled in all versions after that, i.e.
1358 the server would just close the socket immediately.
1360 yaz-client emits a better message when receiving an unrecognised
1361 userInformationField.
1363 Skip zero-length subfields when decoding ISO2709. This rare case happens
1364 if a record has two FS characters in a sequence. Without this patch
1365 there would be a reference beyond char array in using_code_len fragments
1368 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1370 --- 3.0.48 2009/08/28
1372 The show command offered by the zoomsh command now takes a 3d optional
1373 parameter type which is what is passed to ZOOM_record. If the type
1374 argument is omitted, "render" is used.
1376 RPN to CQL conv may use USE string attributes (bug #2978).
1378 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1380 --- 3.0.47 2009/07/08
1382 Function yaz_xml2query allows a diagnostic element in the PQF XML
1383 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1384 code and additional info respectively.
1386 The BER BOOLEAN is now the integral type Odr_bool which still happens
1387 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1388 typedef'd to Odr_int. This is still an integral 'int', but it may be
1389 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1390 ASN-1 compiler as well as programs has been updated to use the new types.
1392 --- 3.0.46 2009/06/08
1394 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1395 only the bibliographic record was rendered. For type=opac, an OPAC
1396 record is only returned if it is present.
1398 iconv: small fix for encoding of advancegreek.
1400 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1402 yaz-client: option auto_reconnect=on really reconnects.
1404 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1406 server: avoid null ptr ref for for yaz_poll errors.
1408 build: fix RPM build for RHEL 5.3.
1410 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1412 --- 3.0.45 2009/03/31
1414 Fixed bug #2709: TCP connect returns Invalid argument.
1416 Fixed compilation for mingw.
1418 Honor charset for raw records (ZOOM_record_get).
1420 Fixed use of errno for threaded mode that was seen on Solaris 10.
1422 Fixed argument passing with blanks in value for Windows Service.
1424 Disable YAZ' own log rotate by default (no 1 GB limit).
1425 The variable l_max_size which specifies the log file limit is set to 0
1426 (DISABLED): This is due to the fact that YAZ is most often deployed using
1427 logrotate. Also YAZ can not perform log rotate because of unsufficient
1428 permissions (setuid).
1430 --- 3.0.44 2009/02/17
1432 List supported encodings in man page for yaz-iconv.
1434 Fixed missing SSL libs for --libs output
1436 Re-established OID record syntax application-xml. Nobody should use it
1437 but we don't want to change soname because of this symbol being absent.
1439 --- 3.0.42 2009/02/02
1441 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1443 Added member named_result_sets for init handler struct for the GFS. This
1444 allows a server to disable named result sets.
1446 Removed OID record syntax application-xml.
1448 Added support for rule-based transliterator for ICU wrapper of YAZ.
1450 Fixed bug #1902: yaz-icu XML output.
1452 Make YAZ checks Emacs friendly.
1454 BITSTRING value shows value. Bug #2346.
1456 ISO2709 decoding: skip control characters from indicator data.
1458 Omit sort key by default in yaz-icu's output.
1460 Allow combined single char options (again) for YAZ' options function.
1462 Utility yaz-marcdump got option to display YAZ version (-V).
1464 Allow YAZ to use ICU 3.4.
1466 Added new ICU test case which illustrates removal of diacritics.
1468 --- 3.0.41 2008/12/29
1470 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1472 --- 3.0.40 2008/12/29
1474 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1477 Fixed bug #2352: yaz-marcdump crashes for certain record.
1479 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1481 Added support for Danmarc2 to UTF-8 conversion.
1483 Added support for ISO5426 to UTF-8 conversion.
1485 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1486 implementation version.
1488 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1490 --- 3.0.38 2008/11/10
1492 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1493 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1495 ZOOM C now interprets databaseName option for ZOOM connection as path
1498 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1500 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1502 Dummy Libxml2 types no longer defined in headers of YAZ'.
1504 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1507 --- 3.0.36 2008/09/26
1509 Various ODR chapter fixes.
1511 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1513 Added missing source for Windows compilation, mutex.c.
1515 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1517 For SRU connections in ZOOM all records up to "count" are now fetched.
1519 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1520 in Windows due to bad error handling for Libxml2.
1522 Added facility for sending arbitrary records (ASN.1 any) using
1523 ZOOM C's Extended service update. Patch by Sam Reynolds.
1525 New options for ZOOM C's connection, logapdu which makes ZOOM log
1528 --- 3.0.34 2008/06/18
1530 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1532 --- 3.0.32 2008/06/12
1534 Fixed memory violation that could occur when decoding UTF-8. This bug
1535 was only present in 3.0.30 of YAZ.
1537 --- 3.0.30 2008/06/06
1539 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1540 GNU TLS is used by default (if found).
1542 yaz-ztest returns OPAC records if a client asks for OPAC.
1544 Improved speed of MARC-8 encoding.
1546 Added support for lossy and loss-less MARC-8 encoding.
1548 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1550 Added new Windows Service wrapper (sc).
1552 yaz-client's itemorder command may now send a file.
1554 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1556 Added new function yaz_log_xml_errors.
1558 Allow (but warn) unknown XML attributes in MARCXML parsing.
1560 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1562 The UTF-8 to MARC-8 conversion now uses a different set of characters
1563 for Greek symbols. Bug #2120.
1565 --- 3.0.26 2008/02/21
1567 Added yaz_daemon (daemon.h).
1569 Fixed bug #2068: pkg-config trouble
1571 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1573 --- 3.0.24 2008/01/28
1575 Document --with-xml2 option.
1577 Added OPAC XML XSD (etc/opacxml.xsd).
1579 Allow glob mask for name attribute in retrieval element for the
1580 generic frontend server's retrieval facility.
1582 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1583 except POLLIN/POLLOUT.
1585 Fixed error handling in cs_listen. Bug #2037.
1587 --- 3.0.22 2008/01/20
1589 Fixed version in yaz/yaz-version.h.
1591 Fixed bug #2027: Crash when closing connection.
1593 Changed configure so that ICU support is only enabled if only ICU
1594 and Libxml2 is available (because the ICU chain is XML based).
1596 --- 3.0.20 2008/01/15
1598 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1599 is built. Only this DLL depends on the ICU runtime.
1601 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1602 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1604 Changed license of CCL module to 'Revised BSD'. After consultation with
1605 remaining members of the original EUROPAGATE consortium, we are re-issuing
1606 the CCL module without a separate license. The software was developed by
1607 Index Data as part of a research project. The special license was included
1608 to help feed usage information back to the project consortium to support
1609 project evaluation. At this time, the project consortium has long-since
1610 disbanded, and the majority of the original principals have retired. At the
1611 same time, we have significantly modified the software during the following
1612 years, to the point where very practically no original code remains. To
1613 simplify re-use of the software, we have contacted those members of the
1614 consortium who could be reached, and agreed to re-issue the module as a
1615 proper part of the YAZ package.
1617 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1619 CQL closer to being version 1.2 compliant. CQL also allows free-form
1620 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1623 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1624 bug could make Extended services handling crash in the ZOOM layer. This
1625 bug was only present in YAZ 3.0.18.
1627 --- 3.0.18 2007/12/19
1629 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1632 yaz-marcdump reads and writes collection wrapped records.
1634 Handle OPAC for record conversion module.
1636 Fixes for ICU wrapper.
1638 Allow ICU libs to be controlled with --with-icu .
1640 --- 3.0.16 2007/11/12
1642 Added yaz_poll which is a wrapper for select/poll. When poll is available
1643 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1644 sockets to be in use.
1646 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1647 functionality through an XML based configuration (ICU chain). This system
1648 is useful for search facilities such as Pazpar2 and Zebra that needs to
1649 perform tokenization of indexed material. The ICU code in a separate
1650 library libyaz3_icu.a.
1652 Added HTTP tunnel facility for COMSTACK, bug #1752.
1653 This is a facility that allows a Web proxy, such as squid, to tunnel
1654 Z39.50 traffic. This facility is "transparent" to must applications
1655 using YAZ. It's enabled by using pseudo transport connect: followed by
1656 the proxy address, followed by command, then follwed by he regular
1657 "virtual" addresss. For example,
1658 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1660 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1662 --- 3.0.14 2007/09/21
1664 Fixed bad memory reference in ZOOM_record - cuased by member not being
1665 initialized. This was a problem only in YAZ 3.0.12.
1667 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1668 fields were not removed.
1670 Changed the way C code is generated from codetables.xml. Made a MARC-8
1671 conversion trie for each characterSet section rather than codeTable.
1672 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1673 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1675 --- 3.0.12 2007/09/12
1677 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1678 from ZOOM_record_error).
1680 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1682 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1684 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1686 Better SRW-to-Bib-1 diagnostic mapping.
1688 ZOOM C and yaz-client announces SRU version 1.2 by default.
1690 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1693 Fixed in yaz_sru_decode to allow other version than 1.1.
1695 --- 3.0.10 2007/08/22
1697 Added support for SRU scan for ZOOM.
1699 Added support for the use of the older versions or Extended Service
1700 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1701 set to the version , 1=first, 2=second, 3=third. The third version is
1702 what ZOOM C has used so far. And that, obviously, is the default.
1704 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1705 therefore in Zebra and in SimpleServer-based applications). The new
1706 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1707 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1708 which is passed into the back-end search callback function.
1710 Added support for HTTP Basic authentication in clients: the SRU/W
1711 codec encodes the username/password elements of the PDU structure
1712 appropriately, and these may be set using the "user" and "password"
1713 options in ZOOM-C applications (the same options that are used for
1714 Z39.50 authentication).
1716 --- 3.0.8 2007/06/25
1718 Fixed bug #1208: SSL appears to be broken in ZOOM.
1720 Fixed bug #1206: Libxml2 include path weirdness.
1722 Added oid_name_to_dotstring.
1724 Allow elementSetName to be specified for ZOOM C record update.
1726 Allow waitAction to be specified for ZOOM C based for Extended Services.
1728 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1729 syntax OID. Bug introduced in YAZ 3 series.
1731 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1733 --- 3.0.6 2007/06/06
1735 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1736 directory. yaz-client now reads commands from file given by option -f
1737 if specified; then tries to read .yazclientrc in current directory.
1738 Failing that, it reads .yazclientrc from user's home directory.
1740 Added support for correlationInfo Note and ID for Record Update via
1743 Added yaz-client command querycharset which specifies character set for
1744 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1745 (termListAndStartPoint).
1747 Charset ISO5428:1984 is an alias for ISO5428-1984.
1749 Implemented a way to perform scan in a result set using Z39.50. This
1750 is achieved by attaching the result set name in the characterInfo
1751 (type InternationalString) of OtherInformation in the Scan Request PDU.
1752 The result set is identified in the otherinformation by the new OID:
1753 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1754 This allows for scan in result set and faceted search . Zebra did some
1755 of this in the APT term using attribute type 8 and value being result
1756 set. Using the OtherInformation approach for this is cleaner and easier
1757 to work with in proxies and the like. This facility can be used in
1758 yaz-client using new command setscan which takes a result set as first
1759 argument, start position (APT) as second.
1761 Changed decoding of SRU XML packed records to deal with servers that
1762 have recordData with XML data with multiple root nodes. Also make
1763 comparison for recordPacking case insensitive. Again, one server
1764 returns "XML" where others return "xml".
1766 For SRU responses allow Content-Type application/xml as well as text/xml.
1768 --- 3.0.4 2007/05/21
1770 Fixed bug in character set conversion of BER strings. Bug introduced
1773 --- 3.0.2 2007/05/08
1775 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1777 For OID class, use oid_class consistently.
1779 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1782 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1783 character set for bibliographic information interchange". By Giannis Kosmas.
1785 Added documentation on new OID API.
1787 --- 3.0.0 2007/05/02
1789 Changes to generic frontend server interface: added new member
1790 'query_charset' for bend_initrequest structure. A backend init handler
1791 should set this member to its native character set for query terms.
1792 When defined, the frontend server logic will announce this character set
1793 to a client if the negotiationModel bit is set by the client. All server
1794 implementors are encouraged to specify this. If a backend server does not
1795 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1797 Added CCL utility to remove terms (stop words) from resulting RPN
1798 tree. This is handled by functions with prefix ccl_stop_words_ .
1800 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1801 terms in RPN queries.
1803 Clean-up the CCL API. Moved some internal structures from ccl.h to
1804 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1805 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1806 This is replaced by ccl_parser_find_str which takes a string instead.
1808 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1809 libyaz.la is the core of YAZ except the generic frontend server and
1810 does not depend on POSIX threads anymore. libyaz_server.la is the
1811 generic frontend server facilities and uses POSIX thread functionality
1812 if available. The libyaz.la no longer depends on POSIX threads because
1813 the number of global structures is limited. NMEM no longer re-uses blocks
1814 between threads ; it simply free's memory immediately but allocates in
1815 "large" chunks as usual. We don't expect any performance penalties
1816 because of this. The yaz_log system is still using a global log_level so
1817 caution must be taken when modifying it with yaz_log_init_.. +
1818 yaz_log_mask_str. This, however, should not cause any trouble because
1819 these functions are called during initialization of application code
1820 anyway. `yaz-config --libs server` returns libs for server applications;
1821 `yaz-config --libs` returns libs for non-server applications.
1823 New OID database - with public definitions in oid_db.h. Removed old OID
1824 database including the head oid.h and definitions such as enum oid_value
1825 and struct oident. The new OID database uses the same string names as
1826 before but the 'protocol' is gone. There are now only two representations
1827 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1828 converts from string to OID; functions with prefix yaz_oid_to_string
1829 converts the other way.
1831 Change to emit_term() in CQL-to-PQF query translation: when a term has
1832 the /regexp relation modifier, do not process it for leading and
1833 trailing "^" and "*", which have quite different meanings in regular
1836 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1837 write handlers no longer carries a 'last' parameter. This will make
1838 yaz_iconv flush "less" characters. A flush is performed by call to
1839 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1841 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1842 removed, because function yaz_query_to_wrbuf does the same.
1844 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1845 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1847 Deprecated MARC utility functions removed.
1849 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1852 Branch split: YAZ_2_1_55_branch
1854 --- 2.1.54 2007/03/16
1856 Fix to ZOOM-C so that transparent reconnection is properly handled on
1857 connections that are in asynchronous mode.
1859 Fixed compilation on OpenBSD 4.0.
1861 Large strings in GRS-1 records are now properly displayed in yaz-client.
1863 Added character conversion support for "advancegreek"; based on patch from
1866 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1867 sequence is met. Before the error was not set so it would be unknown.
1869 Adjust yaz-marcdump MARC reader so that it skips until record separator
1872 --- 2.1.52 2007/03/07
1874 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1875 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1876 fd_set structure used as a bitmask for the FDs to be selected on.
1878 Using ACX_PTHREAD macro to check for POSIX threads.
1880 Fixed have-vsnprintf check.
1882 --- 2.1.50 2007/02/23
1884 Fixes for configure on BSD. Bug #900.
1886 Added snprintf/vsnprintf wrappers for systems that don't have
1887 limits (heavens forbid).
1889 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1890 created before all previous tasks were completed and removed from the
1891 task queue, the new task could be removed by a mistake.
1893 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1895 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1897 Fixed bug #832: Problem with MARC/charset in yaz-client.
1899 Fixed bug #668: save command line history for yaz-client.
1901 Fixed bug #830: pkg-config support.
1903 --- 2.1.48 2007/01/23
1905 Extended ZOOM result set options with two options that may be read by
1906 a client: resultSetStatus and presentStatus with values as specified for
1908 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1910 Fixed bug #827: Using SSL fails on Debian etch.
1912 Fixed bug #826: Weird looking chars for set of MARC records.
1914 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1915 that is treated as an ItemOrder with itemRequest being an XML document
1916 external. The value of "doc" is the content.
1918 Extended the GFS search facility. New member of bend_search_rr
1919 'estimated_hit_count' signals that hits is known to be an estmate
1920 (higher or lower than real hit count). New member 'partial_resultset'
1921 signals that the search was partial (hit count is lower or equal than
1922 real hit count). For Z39.50, the information is stored in resultSetStatus
1923 member of SearchResponse APDU. For SRU, the information is signalled
1924 via SRU diagnostic 59: "Result set created with valid partial results
1927 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1929 --- 2.1.46 2007/01/13
1931 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1933 Added ZOOM_connection_peek_event.
1935 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1936 the following new functions:
1937 ZOOM_event_nonblock, ZOOM_connection_process,
1938 ZOOM_connection_get_{socket,mask,timeout},
1939 ZOOM_connection_fire_event_{timeout,socket}.
1940 The existing blocking event handler, ZOOM_event, is a wrapper for the
1941 + blocking ZOOM_event_sys_{poll,select}.
1943 Implemented function ccl_xml_config which parses XML version of CCL
1944 configuration (bug #798).
1946 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1948 Added timings utility (yaz/timing.h)
1950 --- 2.1.44 2007/01/03
1952 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1955 Fixed bug #779: Rotation of apdu.log fails.
1957 Fixed for character set conversions:
1958 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1959 Honor G1 set in MARC-8 decoding.
1961 --- 2.1.42 2006/12/17
1963 Fixed bug #775: char conversion does not handle Alternative UTF-8
1966 Implemented function yaz_marc_read_line which parses MARC line format
1967 records. There is a wealth of formats out there. So far, this function
1968 reads line records produced by yaz_marc_write_line.
1970 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1971 more generic and easier to remember(!) options: -i format and -o format
1972 which specifies input format and output format respectively - where
1973 format is one of "marc", "marcxml", "line", "marcxchange".
1975 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1976 does not print anything except warnings for records.
1978 For yaz-marcdump, added support for MARC split into files (-s) with a given
1981 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1982 spec, at http://www.loc.gov/standards/sru/record-update/
1983 This has changed the binary layout of the following structs:
1984 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1985 bend_update_rr . Patch by Ko van der Sloot.
1987 Added GFS utility function bend_assoc_is_alive which returns 1 if
1988 association is still alive (client is connected); 0 otherwise (client
1989 closed connection). This allows busy servers to stop working for
1992 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1993 been a separate piece of software. This version of ziffy has been modified
1994 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1996 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1998 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1999 Client code may now interrogate options such as "init_opt_sort" to
2000 find out whether the server claims to support various options.
2002 --- 2.1.40 2006/11/27
2004 Added utilities yaz_{set,get}_esn to set/get element set name from
2007 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2008 of YAZ and has been so since YAZ 2.1.10.
2010 Implemented ZOOM_record_error which returns error information for
2011 record (surrogate diagnostic).
2013 --- 2.1.38 2006/10/31
2015 Updates for SRU Update by Ko van der Sloot:
2016 1. Changed name from "operation" to "action"
2017 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2018 versions in the code, marked as 'backward compatible'.
2019 3. Added diagnostics for SRU Update.
2021 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2023 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2025 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2027 For GFS, fixed problem with SRU diagnostic 'First record position out of
2028 range' being issued for 0 hits.
2030 zoomtst10 part of Windows Build.
2032 --- 2.1.36 2006/10/13
2034 Implemented yaz_filepath_comp which splits a path into file path
2035 components (required by Zebra 2.0.3+).
2037 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2038 BSD inspired license until now so this should not have any real impact on
2039 anybody. See http://www.opensource.org/licenses/bsd-license.php
2041 Fixed bug #687: Missing log lines.
2043 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2046 Fixed bug #689: SRU diagnostics to be added.
2048 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2049 whether a connection is idle (no more work do do).
2051 --- 2.1.34 2006/10/04
2053 Change type of optval from long to int for invocation of setsockopt with
2054 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2056 Added support for specifying the max log file size for the Generic
2057 Frontend Server. The size is given with option -r.
2059 --- 2.1.32 2006/09/21
2061 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2063 --- 2.1.30 2006/09/17
2065 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2068 Fixed bug in Generic Frontend Server that could cause a server to stop
2069 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2071 For the generic frontend server, the maximum record size is used as maximum
2072 size of incoming packages (SRU + Z39.50). The value until was previously
2073 only used in Z39.50 Init negotiation and, later, in a session controlled
2074 sizes of records returned. This is controlled using -k option. It can be
2075 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2077 --- 2.1.28 2006/09/04
2079 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2082 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2084 New option for yaz-marcdump -lpos=value which allows setting a portion
2085 of MARC header to a certain value.
2087 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2089 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2090 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2092 --- 2.1.26 2006/08/15
2094 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2097 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2099 --- 2.1.24 2006/08/08
2101 Fixed MARC ISO2709 encoding routines to deal with character set
2104 Minor changes to GFS logging. Database included in search request log
2107 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2108 cached/multiple records.
2110 Shared libraries are built by default on Unix+configure.
2112 Changed cql2pqf transformation to use a different evaluation order. The
2113 new order is: always, relation, structure, position, truncation, index
2114 and relationModifier. Old order was: always, relation, relationModifier,
2115 structure, index, position, truncation. Note that the the latter ones
2116 override former ones for identical attributes.. The new scheme means that
2117 it is possible to override any existing attribute with a relationModifier.
2118 And also that it is possible to override everything for the index rule
2119 (except the ones listed in relationModifier). No order is perfect but this
2120 one, we believe, covers more real cases.. The "always" should have been
2121 called "default", since the attributes there can be overridden with all
2124 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2125 compilation phase, but also for yaz-config --cflags output. This allows
2126 us to have public headers with Libxml2 stuff in them . It should also,
2127 eventually, make Libxml2 checks redundant in packages using YAZ, such
2130 --- 2.1.22 2006/06/15
2132 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2133 stored in uri, message and details.. Previously diagnostics were stored
2134 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2135 compatibility.. but he's probably the only one affected, so.
2137 Added support for CCL, compiled on the client side, in ZOOM-C. This
2138 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2139 input; the resulting query objects can be used for for searching with
2140 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2142 YAZ' configure searches for OpenSSL by default.
2144 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2145 SL_CTX_use_certificate_file. See
2146 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2147 for more info. Thanks to Ko van der Sloot.
2149 --- 2.1.20 2006/06/02
2151 Bug #600: SRU GET, POST support for yaz-client. Introduced
2152 command 'sru' which selects method SOAP/GET/POST.
2154 Allow missingValueAction to be specified for the sortspec string -
2155 function yaz_sort_spec. By default, the missing value action is null.
2156 Use ! to specify "abort". Use = followed by stringvalue to specify default
2159 Ensured that Present-handler (if defined) is called in GFS before any call to
2160 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2161 searchRetrieve requests.
2163 Documentation for YAZ is now based on the Docbook XML/XSLT using
2164 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2165 is no longer depending on jade/openjade or docbook-to-man scripts.
2166 PDF is no longer part of the distribution - but can optionally be
2167 made using DSSSL/jadetex or FOP.
2169 Added retrieval handling support in Generic Frontend Server to support
2170 conversion between MARC/XML as well as XSLTtransforms. See
2171 etc/yazgfs.xml for an example.
2173 Added Authentication support to Generic Frontend Server in SRU
2174 mode. Authentication using HTTP Basic is supported, as is the use
2175 of 'x-username' and 'x-password' parameters in the request itself.
2177 Added support for a new character set MARC8s identical to MARC8 except
2178 that it converts combined characters to single Unicode characters in the
2179 Latin-1 range (when possible).
2181 --- 2.1.18 2006/04/24
2183 ASN.1 compiler 0.4: generates brief Doxygen file header for
2184 generated .h/.c files.
2186 Utility yaz_iconv now supports conversion to MARC-8.
2188 New facilities for the MARC module. The reading - and writing of
2189 content are separate methods for the yaz_marc_t handle. The following
2190 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2191 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2192 format). Write functions have prefix yaz_marc_write_.. The existing
2193 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2194 available. Removed support for OAI-MARC and simplexml (not the
2195 simplexml from PHP5).
2197 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2198 to be returned for this connection.
2200 --- 2.1.16 2006/03/31
2202 Allow multiple languages and charsets to be specified with
2203 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2204 negcharset iso-8859-1,utf-8
2206 Translation of proximity nodes from CQL into PQF now works.
2208 Moved to automake 1.8, 1.9.
2210 Added function yaz_log_set_handler which allows a log handler to be
2211 installed. This handler will be called for all log messages. Output
2212 to file is also produced; but that can be disabled by passing NULL
2213 fname to yaz_log_init_file.
2215 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2217 For SRW (including GFS), accept application/soap+xml as content-type
2220 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2221 produces NO stylesheet reference even if a default stylesheet is specified
2224 --- 2.1.14 2006/03/14
2226 Updated Windows package to include yazd.dll + yazd.lib for the
2227 Development component.
2229 If the environment variable YAZ_LOG is set, then it is used as a
2230 string indicating the default level of logging to use if not
2231 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2232 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2233 used as before. So, for example, to omit warnings from YAZ logging,
2234 export YAZ_LOG=-warn
2236 cql_transform() now map structure and other attributes before indexes,
2237 so that index-specific structures and other attributes can override
2238 defaults. So now a combination of mapping specifications such as:
2240 index.dc.date = 1=date-modified 4=5
2241 does the right thing.
2243 cql_transform() now also respects the "always" mapping specification,
2244 which establishes an initial set of attributes to be used for all
2245 terms except where overridden by more specific attributes associated
2246 with the index, relation or modifier.
2248 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2249 which mode to use; one of "post", "get" or "soap" (SRW, default).
2251 Fixes for yaz_iconv routines: changed trie-based character set conversions
2252 to use only non-negative values for bit fields due to Sun's C compiler not
2253 supporting negative values.
2255 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2256 sequences where not read correctly. Fix by Rustam Usmanov.
2258 Updated win/makefile to use options, settings which makes things
2259 compile with VS C 2005.
2261 --- 2.1.12 2006/02/01
2263 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2265 In ZOOM socket code, use select instead of poll on MacOSX.
2267 ZOOM-C now support client-side compilation of CQL into RPN that is
2268 sent to the server, enabling CQL to be used against all Z39.50
2269 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2270 ZOOM_query object, and submit it using ZOOM_connection_search().
2271 The CQL-to-RPN translation uses a configuration file, the name of
2272 which must be specified in the Connection's "cqlfile" option.
2274 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2275 function, which takes as its start-term parameter a ZOOM_query object
2276 (which may have had either CQL or RPN set into it).
2279 --- 2.1.10 2005/11/29
2281 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2282 GFS to support this as well. Backend handler, bend_srw_update, does the
2283 update work. Code contributed by Ko van der Sloot.
2285 Allow retrieval of Search Result-1 information in ZOOM by the use of
2286 options that are attached to a result set. ZOOM documentation updated
2289 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2290 UTF-8 conversion. Patch by Raj Patel.
2292 Added option -m to GFS to control formatting of timestamps in log file.
2294 Added 'exit' as synonym for 'quit' in yaz-client
2296 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2297 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2298 for the new members. Patch by Ko van der Sloot.
2300 Added support for SRU POST. It is supported for content-type
2301 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2303 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2304 Instead make the library libyaz.la multi-threaded. Threading as a whole
2305 can still be disabled by configure option --disable-threads. Previosly,
2306 with older GLIBCs there were problems with MT libs under Apache. This
2307 has now been fixed a long time ago.
2309 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2312 CQL module modified to be case insensitive for relations/indexes/operations.
2314 Fixed bug in CQL transform code: incorrect value relationModifieder
2317 Added 'show all' command for yaz-client which retrieves all results
2320 Added new yaz-client, xmles, which takes a (private) OID and
2321 a document to be sent as an extended service request.
2323 Describe new yaz-client commands wait_response and set_auto_wait.
2325 Increase TCP/IP listener backlog from 3 (which I am guessing was
2326 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2327 that the socket will queue as many incoming connections as it's able
2328 to handle ongoing connections. In other words, it will never now
2329 refuse a connection that it would be able to handle merely because
2330 it's not got around to accepting() enough of the pending connections
2331 yet. This is the behaviour anyway under Linux, where the listen()
2332 argument is ignored; but not under BSD and on systems such as
2333 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2334 YAZ-based servers should now be uniform across operating systems in
2337 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2338 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2339 This allows yaz-marcdump to read large MARC batches (>2 GB).
2341 Modified all YAZ source files - except the source which is auto-generated
2342 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2345 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2346 corresponding to the existing *_setl() function. These allow option
2347 values containing arbitrary valuues.
2349 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2350 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2351 except that it returns an indicator of whether or not the sort
2352 criterion was accepted (0 for OK, -1 for invalid).
2354 --- 2.1.8 2005/06/07
2356 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2357 MARC output rather than returning "new" buffer.
2359 yaz-client warns about unknown init options.
2361 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2363 --- 2.1.6 2005/05/24
2365 Added support for SRW sort in Generic Frontend Server. Patch
2366 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2367 sortKeys - or NULL if none is provided.
2369 Fixed bug #307: It was impossible to specify indefinite/no timeout
2370 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2373 Added support for multiple languages and charsets to be specified in
2374 ZOOM. Each charset/language is separated by a blank. If negotiation is
2375 in effect in init-response, Option
2376 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2377 Code based on patch by Vasiliy Osadchuk.
2379 Fixed bug #306: infinite recursion that occurred when calling
2380 yaz_log_level_init as the first call (before other log level or
2383 Fixed bug in scan handling in front end server: if preferred-Position-In-
2384 Response was non-present, a NULL pointer referece was performed.
2386 --- 2.1.4 2005/04/26
2388 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2389 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2390 now defined for all those error codes. So instead of putting 109 in
2391 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2392 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2394 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2397 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2399 Program yaz-client now exits and produces an error message if multiple
2400 Z39.50 servers are specified on the command line (none or one allowed
2403 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2406 --- 2.1.2 2005/03/16
2408 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2410 Fixed bug #272: Preserve spacing for CCL terms.
2412 --- 2.1.0 2005/03/14
2414 Added support for virtual hosts and multiple backend servers for
2415 the YAZ frontend server. The configution is XML based and
2416 support specificition of CQL to RPN mappings and explain information.
2417 See section "Virtual Hosts" in the YAZ manual.
2419 Extended OPAC display utility. OPAC display utility renders
2420 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2421 to supplement yaz_marc_decode_wrbuf.
2423 Fixed a bug in MARC decoder that could caused it to crash for some
2424 invalid MARC records. More diagnostics and warnings where added in
2425 XML output (warnings, etc are stored in comments).
2427 --- 2.0.34 2005/02/08
2429 Fixes for UNIX domain sockets. Bug #261.
2431 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2433 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2434 Added yaz_marc_subfield_str which defines subfield lead string which is
2435 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2436 yaz_marc_endline_str which defines end of fields string used in
2437 YAZ_MARC_LINE format. Default string is newline.
2439 Experimental support for MarcXChange. This format can be produced
2440 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2441 http://www.bs.dk/standards/MarcXchange.xsd
2443 Added yaz-client commands scansize that sets maximum number of
2444 entries to be returned by scan.
2446 --- 2.0.32 2005/01/11
2448 Added support for SRW scan in yaz-client and Generic Frontend Server.
2450 * Added whereInList member to SRW Scan Term.
2452 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2454 Fixed NMEM system to return aligned blocks on the smallest boundaries
2455 that are suitably aligned for all possible types on the particular
2456 architecture YAZ is being built for.
2458 --- 2.0.30 2005/01/04
2460 Fixed numerious warnings that was issued with newer versions of GCC.
2462 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2463 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2466 Make YAZ Generic Frontend Server slightly faster.
2468 Enhance (and reduce) logging for Generic Frontend Server.
2470 Revert YAZ log system so that it flushes every write operation
2471 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2473 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2474 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2475 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2476 will effectively disable old definitions.
2478 --- 2.0.28 2004/11/09
2480 Added yaz_log_time_format which specifies log format using
2483 Added yaz_log_module_level which returns mask for a module. Value
2484 is non-zero mask a if module is enabled; zero if disabled.
2486 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2487 in include/yaz/cql.h.
2489 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2491 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2493 Fixed bug #172: RPM builds does not enable SSL.
2495 Doxyfile.in part of dist. Doxyfile generated by configure.
2497 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2498 are given and the corresponding component does not exist.
2500 Extend CCL documentation in YAZ reference. Describe r=r.
2502 --- 2.0.26 2004/10/01
2504 Fixed MARC->MARCXML conversion to properly deal with
2505 fields, subfields, indicators having non-ASCII characters.
2507 Fixed MARC->MARCXML conversion so that ASCII control characters
2508 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2511 Added YAZ GFS support for conversion from Z39.50 surrogate
2512 diagnostics to SRW surrogate diagnostics.
2514 Bug fix: YAZ GFS did not return schema in explainResponse.
2516 --- 2.0.25 2004/09/30
2518 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2519 now converts recordSchema to elementSetName as well as schema URI.
2521 Fixed bug in COMSTACK that prevented HTTP request packages from being
2524 --- 2.0.24 2004/09/29
2526 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2527 does not require white-space before and after the dash in a range, e.g.
2528 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2531 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2532 due to new GCC removing "redundant" code.
2534 Added yaz-client commands scanpos and scanstep that sets preferred
2535 position and step-size for scan.
2537 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2539 Added CCL utility ccl_qual_buf which parses one or more CCL
2540 spec lines in a buffer.
2542 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2543 of name and value - ignoring empty lines and comments.
2545 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2547 Added odr_get_element_path which returns current element path for an
2548 ODR handle. This utility is useful in error handling or user-defined
2551 Added ODR_PRINT utility odr_set_stream which is is a more generic
2552 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2553 to a write function and pointer to close function. The close function - if
2554 non-NULL - will be called during odr_destroy.
2556 Fixed bug in CCL parser where truncation char was not removed from
2557 right side when truncation=both was in effect.
2559 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2562 --- 2.0.23 2004/08/11
2564 Fix buffer overrun in CQL parser when dealing with proximity (%).
2566 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2567 to UTF-8/UCS conversion is now only based on codetables.xml.
2569 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2571 --- 2.0.22 2004/08/06
2573 Add support for more "commit changes" in ZOOM (uses Extended Services).
2575 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2578 Yet another small fix for configure of SSL.
2580 --- 2.0.21 2004/05/14
2582 Fix SSL libs for configure when --with-openssl=DIR is given.
2584 --- 2.0.20 2004/05/10
2586 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2588 SSL comstack now uses yaz.pem certificate file on server side
2589 by default. Certificate filename can be configured by calling
2590 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2592 Fix bug regarding multiple calls to ZOOM_connection_connect.
2594 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2596 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2597 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2599 ZOOM now allows inspection of X509 peer certificate for verification.
2600 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2602 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2603 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2604 as "modular" but it simplifies things.
2606 Added cs_get_peer_certificate to that returns peer X509 PEM.
2608 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2609 NULL if SSL is unavailable.
2611 Documentation about MARC decoding tools.
2613 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2615 --- 2.0.19 2004/03/30
2617 Rename CHANGELOG to NEWS to follow GNU style packing.
2619 Fix bug with missing initialization of member in init_diagnostics.
2620 This bug affects threaded version of GFS server.
2622 --- 2.0.18 2004/03/20
2624 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2627 Ensure zlib.dll is packed with Windows install.
2629 --- 2.0.17 2004/03/17
2631 Fix encoding of xsd:string to use text instead of CDATA.
2633 Fix endless loop in CQL parser with unbalanced ".
2635 Use a more compact way to store MARC-8 conversion tables.
2637 --- 2.0.16 2004/03/16 Debian only
2639 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2642 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2647 --- 2.0.15 2004/03/01
2649 Another fix for decoding of XML packed records.
2651 --- 2.0.14 2004/02/25
2653 Fixes for Chunked encoding. White space not ignored after length spec.
2655 Update NS and use default NS for SRW diagnostic elements.
2657 --- 2.0.13 2004/02/23
2659 Implement ZOOM_resultset_cache_reset which resets record cache.
2661 Implement ZOOM_resultset_sort which sorts a result set.
2663 Implement chunked HTTP transfer.
2665 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2667 --- 2.0.12 2004/02/16
2669 Added member 'schema' to bend_explain_rr structure so that backend
2670 can specify explain record identifier. Defaults to Zeerex 2.0.
2672 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2674 --- 2.0.11 2004/02/16
2676 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2679 Added init command for yaz-client which sends "extra" init request.
2681 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2682 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2684 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2686 Make ZOOM error code for "invalid query".
2688 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2690 --- 2.0.10 2004/02/05
2692 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2695 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2697 Added option -p <file> to make Generic Frontend Server to write PID file.
2699 Added option -D to put Generic Frontend Server in background on its own.
2701 Make ZOOM C recognize option "password". If unset, "pass" is used
2702 (for backwards compatibility).
2704 Fixed a bug in Generic Frontend Server that could make it crash if a
2705 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2708 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2709 Must be issued before open, in order to be in effect.
2711 --- 2.0.9-6 2004/01/12 Debian/Windows
2713 Make the SRU server more picky WRT unknown params, etc.
2715 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2717 New YAZ client command, options, that sets Z39.50 options.
2719 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2720 options from a string of tokens (one token for each option bit).
2722 Update SRW diagnostic code messages.
2724 --- 2.0.9-5 2004/01/07 Debian/Windows
2726 Handle user defined stylesheet for SRW/SRU.
2728 --- 2.0.9-4 2004/01/06 Debian/Windows
2730 Fix bug in decoding of Content-Length.
2732 --- 2.0.9-3 2004/01/06 Debian/Windows
2734 Fix a bug with decoding of XML packed records.
2736 --- 2.0.9-2 2004/01/05 Debian only
2738 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2740 Fix bug in SRW/SRU diagnostics decoding.
2742 --- 2.0.9 2004/01/05
2744 Fixed bug in Generic Frontend Server which could drop records exceeding
2745 preferred message size. Reported and fixed by Irina Dijour.
2747 Fixed calculation of package size for structured records in Generic
2748 Frontend Server. Reported and fixed by Irina Dijour.
2750 Fixed namespace for SRW/SRU diagnostics.
2752 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2754 --- 2.0.8 2003/12/22
2756 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2757 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2760 CQL changes to reflect recent changes to the specification:
2761 * Documentation talks about context sets instead of index sets.
2762 * Documentation talks about indexes instead of qualifiers.
2763 * The CQL-to-PQF transformer's configuration file now uses
2764 "index.set.name = <attributes>" instead of the old form
2765 "qualifier.set.name = <attributes>". (Both forms are still
2766 understood but the latter is deprecated.)
2767 * CQL terms with no explicit index specified are now interpreted as
2768 cql.serverChoice instead of srw.serverChoice (which of course
2769 behaves exactly the same.)
2771 --- 2.0.7 2003/12/16
2773 MARC conversion can now generate ISO2709 output in another
2774 character set. yaz-marcdump uses this facility if you invoke it
2777 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2778 functions from there can be used from C++.
2780 --- 2.0.6 2003/12/04
2782 Frontend server now transfers memory from decoded packages to stream
2785 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2786 references to show up.
2788 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2789 the ZOOM Abstract API. The older names for the same options are still
2790 also supported for the benefit of old applications.
2792 ZOOM-C supports "implementationId" and "implementationVersion" options
2793 to go along with "implementationName". These allow the user code to
2794 specify identification strings to be sent to servers.
2795 Add OID for the new ExtLite attribute set.
2797 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2798 as requested/supplid by Ere Maijala <ere@atp.fi>
2800 For generic frontend server, reverse the order of
2801 "toolkit-supplied / application-supplied" strings sent as implementationId,
2802 Name and Version. Also, remove the spaces around the slash. This brings
2803 the GFS in line with the behaviour of ZOOM-C on the client side.
2805 Add function ZOOM_scanset_display_term.
2807 yaz-client shows scan displayTerm if present.
2809 Utility yaz-iconv is now installed by default along with the man page
2812 Extend configure check for OpenSSL to use pkg-config where available (such
2815 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2816 server to specify uid/gid/mask for socket using the format
2817 unix:[user=uid,][group=gid,][umask=mask,]file=path
2818 If file= is omitted the existing format is assumed, e.g.
2820 in which case the mask is 0666 (rw for everybody).
2822 Major restructure of YAZ source. All source in libyaz is in src directory.
2823 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2824 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2826 Added man page for utility yaz-marcdump (used to be called marcdump).
2827 yaz-marcdump is installed by 'make install'.
2829 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2830 of incoming package failed.
2832 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2834 Change prototype of odr_perror: add const to message string.
2836 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2838 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2839 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2840 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2841 DNS lookup. There should not be any compatibility problems with this
2842 assuming that blocking=1 or 0 is used.
2844 Fix bad reference in UNIX comstack in function cs_addrstr.
2846 Fix for compilation on AIX.
2848 The generic front-end server (server/seshigh.c) now supports returning
2849 Init diagnostics to the client in User-information-field, in
2850 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2853 --- 2.0.4 2003/09/04
2855 Allow any CQL relation (not just all,any,exact,scr).
2857 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2858 that features the same UI.
2860 Implemented command update0 in YAZ client which is equivalent to
2861 update but uses old of Ext Update ASN.1.
2863 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2864 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2865 Previously no OID was used for this info.
2867 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2868 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2869 returns 'malformed search term' otherwise.
2871 SortResponse member resultCount now set to NULL in sort handler of
2874 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2877 Add three new utility functions for translating OIDs between various
2878 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2879 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2880 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2881 char *oid_to_dotstring(const int *oid, char *oidbuf);
2882 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2884 Reverted modifications for ES Update definition for z_IU0Update
2885 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2886 is back to YAZ 2.0.2.
2888 String value attributes for CCL parser.
2890 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2891 which their FirstSearch server returns in Init responses, sometimes
2892 carrying useful diagnostic information when Init fails. This has the
2893 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2894 "z39.50/oclcui.asn", where its definition is somewhat different from
2895 what OCLC document on their web-site, as required to interoperate with
2898 Support for anonymous authentication in yaz-client. Use the command
2901 * Fix the OID of the Index Data-local "admin" Extended Service from
2902 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2903 the 1000, which indicates a locally-defined OID, was a mistake.
2905 --- 2.0.3 2003/06/20
2907 Fix CCL directive @case handling so that it affects string match for
2908 both CCL keywords and qualifiers.
2910 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2911 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2912 Decoder has been updated with ASN.1 changes as listed in
2913 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2914 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2915 z_IUUpdate, remains unchanged.
2917 ZOOM_record_get may now return a record in a specific character set.
2918 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2919 "from" is the character set of record as returned by target. "to" is
2920 the character set to be returned. If omitted, "to" is UTF-8.
2922 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2924 New ODR utility, odr_getelement, which returns name of element for
2925 which encoding/decoding failed.
2927 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2928 in cases where a required element was omitted.
2930 Bug fix: some MARC8 sequences were not converted.
2932 New ZOOM option "step" which specifies number of records to be
2933 retrieved in one chunk. Used in conjunction with "start" and "count".
2935 SRW support for yaz-client. Use scheme http: to use it, e.g.
2938 yaz-client no longer does (un)intelligent character set conversions
2939 by default. Can be enabled with charset and marc_charset commands.
2941 xmalloc trace fix for 64-bit systems such as DEC alpha.
2943 Solaris 2.6 compile fix.
2945 New function, cql_strerror() translates SRW error codes, as returned
2946 by cql_transform_error(), into human-readable English strings. Used
2947 in yaz-client diagnostics when appropriate.
2949 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2950 converts it into a type-1 query which is sent to the server. This
2951 makes CQL available for use with all Z-servers, as opposed to the tiny
2952 minority that can handle CQL queries themselves.
2954 --- 2.0.2 2003/04/28
2956 New Debian package layout similar to the Redhat Package layout.
2958 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2959 and search result respectively.
2961 --- 2.0.1 2003/04/25
2963 Redhat package is now several packages: libyaz (runtime libraries),
2964 libyaz-devel (development and documentation, and yaz (utility programs).
2965 Package spec file by Morten Bogeskov.
2967 New member 'schema' in struct bend_fetch_rr which the name of requested
2968 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2969 handler MAY set this to reflect the schema of the returned record.
2971 New member 'display_term' in struct scan_entry. GFS now sets member entries
2972 and allocates scan entries to be filled by user scan handler. In previous
2973 version, entries member was allocated by the scan handler. That still works,
2974 but the GFS will ignore member display_term - assuming it was NOT set by
2975 the handler. The fact that the GFS now allocates the entries both allows
2976 for new members and makes a scan handler easier to write.
2978 Fix CQL lex buffer overflow.
2980 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2981 SRU default recordPacking is string.
2983 SRU protocol support for frontend server.
2985 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2987 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2989 Added scan for the ZOOM shell (zoomsh).
2993 * String Identifers for Schemas (Amendment 5).
2994 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2995 Old definition for schema
2996 Odr_oid *schema; /* OPT */
3001 Z_InternationalString *uri;
3002 #define Z_Schema_oid 1
3003 #define Z_Schema_uri 2
3006 * resultCount parameter to Sort Response (Amendment 1).
3007 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3009 Support for SRW 1.0 over HTTP. This is an optional feature and
3010 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3013 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3014 on the same port. SRW SearchRetrieveRequests are mapped
3015 to bend_init,bend_search,bend_fetch,bend_close.
3017 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3019 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3020 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3022 ZOOM connections are SRW based if schem http is used for hostname
3023 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3024 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3026 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3027 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3028 distance=n, order=true/false, relation=le, prox unit=word. If
3029 n is omitted, distance 1 is used.
3031 Fixed problem with C compiler include path in wrong order.
3033 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3034 on Solaris. Patch from Ko van der Sloot.
3036 New MARC decode API. All new functions operate on a yaz_marc_t
3037 handle. The most important new functions are: yaz_marc_create,
3038 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3039 decode and destroy respectively. Decoder can produce formats
3040 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3041 include/yaz/marcdisp.h.
3043 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3044 to UTF-8, UCS-32, wchar_t or Latin-1.
3046 * Prototypes for yaz_iconv_-functions moved to separate header
3047 include/yaz/yaz-iconv.h.
3049 Make a few private functions 'static' in unix.c. This prevents
3050 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3052 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3053 are set when Init Response is received.
3055 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3056 but returns diagnostic set as well.
3058 New function yaz_strerror which is a portable wrapper for
3059 strerror/strerror_r/GetLastMessage.
3061 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3062 is returned for MARC. If type is "oai", then OAI MARC is returned.
3064 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3067 --- 1.9.2 2002/11/26
3069 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3071 Fix bad race conditions on SIGTERM and terminate gracefully in
3074 Move retrieval (data1) module to Zebra since nobody seems to be
3077 Add GRS-1 render for ZOOM using same format as yaz-client.
3079 --- 1.9.1 2002/10/05
3081 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3083 Fix broken ESpec handling in data1 module.
3085 SGML reader parses comments and makes them part of the data1 tree.
3087 Added several type casts so that YAZ compiles as C++ code.
3089 ZOOM didn't handle PDU encoding failures properly.
3091 Added more Bib-1 diagnostics (approved extensions).
3093 GNU configure: better check for iconv.
3095 More portable use of accept, getpeername. Check for socklen_t. Use
3096 int/size_t if socklen_t is not defined.
3100 PQF parser rejects bad queries - including those with extra
3101 characters in them. PQF parser used to silently ignore that.
3102 Cleaner API for PQF added, which allows you to get detailed
3103 error information for bad queries (see yaz/pquery.h).
3105 Fixed bug in ZOOM_record_get for type "database".
3107 Implemented mini iconv library supporting conversions between
3108 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3110 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3112 --- 1.8.9 2002/08/20
3114 Fixed ZOOM C record cache so that preferredRecordSyntax and
3115 elementSetName is used to check for already fetched records.
3117 --- 1.8.8 2002/08/02
3119 Added three members in bend_initrequest structure to facilitate
3120 character set negotiation.
3122 Fixed a bug in frontend server that could cause indefinite
3123 loops under rare conditions.
3125 Revised character set utilities (charneg.h) so that encoding
3126 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3128 For PQF, directive @term <type> sets term type for Scan/Search.
3129 Here <type> is general, string, numeric, null. The term type
3130 is inherited - just like @attr.
3132 New call odr_set_charset that sets character set conversion for
3133 international-strings on a ODR stream. Prototype is:
3134 int odr_set_charset(ODR o, const char *to, const char *from);
3135 The InternationalString is still represented as C string in YAZ
3136 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3137 won't). On the protocol level, you can use any encoding.
3139 Support for UNIX sockets in ZOOM.
3141 Solaris recv sometimes returns errno == ENOENT. It is treated as
3142 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3144 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3145 both client and server. Code by Morten Bogeskov.
3147 --- 1.8.7 2002/05/22
3149 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3150 that they can be used directly from Visual Basic. You must recompile
3151 your windows APP if you're using ZOOM.
3153 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3154 Commands "lang" and "charset" sets language and character set respectively.
3155 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3156 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3158 Attributes from multiple CCL fields may be OR'ed rather than merged
3159 using directive "@field or". Fields are still merged by default -
3160 equivalent to "@field merge".
3162 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3165 Fixed bug in zget for parameter ExtendedServicesResponse.
3169 --- 1.8.6 2002/03/25
3171 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3173 Client displays USR.1:SearchResult-1 (hits per term).
3175 Additional Search Info for search in Generic Frontend Server.
3177 Fixed CCL parsing of "field=s".
3179 WIN32 installer - using the excellent NSIS software from nullsoft.
3181 Fixed CCL parsing of "field = - <number>".
3183 Added function yaz_marc_decode that decodes MARC for line mode
3184 display or XML (similar to that used by JZKit).
3186 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3187 Z39.50. But ISO/ILL was, however.
3189 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3190 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3192 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3193 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3195 --- 1.8.5 2002/02/03
3197 New YAZ client features: Command completion and new commands:
3198 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3199 Code provided by Jacob Poulsen.
3201 New call oid_trav, that visits all registered OIDs via callback.
3203 Function ZOOM_record_get now returns const char pointer rather than
3204 void pointer. It saves a lot of type casts.
3206 For YAZ client, command "auth" now allows you to set authentication
3207 in IdPass style. It is enabled when three tokens are given - order
3208 is user, group and password.
3210 Fix memory leaks in MARC record handling for ZOOM.
3212 New option for YAZ client, -k <kilobytes> that sets
3213 maximum record size. Similar to -k option for generic frontend
3214 server and yaz-ztest.
3216 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3218 Prefix query parser reports "fail" when bad attribute set is given.
3220 Fix in MARC decoder. Proximity logging. Fix for attribute set
3221 in scan handler for server. Patches by Shigeru Ishida.
3223 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3226 Configure option --with-openssl=<dir> now works when a directory is
3227 specified. Patch provided by Morten Bogeskov.
3229 New option for YAZ client, -u <auth>, that sets authentication.
3231 ZOOM fix: error information was sometimes "missing", since error
3232 was cleared/reset too when it shouldn't.
3234 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3236 --- 1.8.4 2002/01/04
3238 Scan for ZOOM API. New object ZOOM_scanset. New functions
3239 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3240 ZOOM_scanset_destroy.
3242 New ZOOM function, ZOOM_connection_last_event, that returns type
3243 of last event (such as "receive data", "send data", "apdu received",
3246 New ZOOM option, schema, that specifies schema for retrieval.
3248 New CCL feature. Qualifiers can be aliases for one or more
3249 other qualifiers (if more than one is given, OR is used).
3251 ZOOM uses named result sets if target supports it.
3253 Two new YAZ client commands: . (dot, which sources a script of YAZ
3254 client commands), and ! (to execute shell command.). Implemented
3257 Working on Debian packages.
3259 --- 1.8.3 2001/11/19
3261 YAZ client enables named result sets only if target supports it.
3263 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3265 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3266 with key="host" to get same result.
3268 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3269 Function Z3950_resultset_record(s) returns references to records
3270 "owned" by resultset. To become owner use Z3950_record_clone.
3272 Function z_ext_record handles Extended Services. Thanks to
3275 --- 1.8.2 2001/11/12
3277 CCL Parser fix: ignore token comma when dealing with and-lists.
3279 Documentation updates for COMSTACK.
3281 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3282 Changed prototype Z3950_records. For some functions, int parameters
3283 were changed to size_t.
3285 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3288 New MARC decode/display function, marc_display_exl, which properly rejects
3289 non-ISO2709 records. YAZ client uses it.
3291 --- 1.8.1 2001/10/29
3293 Fix bug: local attribute set wasn't set correctly in PQF strings.
3297 * Old Z39.50 codecs no longer supported.
3299 Added ZOOM C binding. See http://zoom.z3950.org/
3301 Renamed states for COMSTACKs to avoid confusion with events.
3303 Implemented cs_look and proper cs_rcvconnect.
3305 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3307 Configure detects POSIX threads on OpenBSD.
3309 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3310 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3312 When error is returned from present handler, non-surrogate diagnostic
3313 is returned in present response (and fetch handler is no longer called).
3315 * Minor adjustments to pquery parser (PQF). Token characters may be
3316 escaped by using backslash (C-style).
3318 PQF parser allows string attribute values to be specified. For @attr,
3319 non-numeric characters after the equal-sign are treated as strings
3320 (e.g. @attr 9=title).
3322 CCL trunction character may be defined (@truncation in file)
3324 * function zget_ExtendedServicesRequest sets waitAction to
3325 waitIfPossible (was wait).
3327 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3330 CCL operator names may be set in field definition files (CCL_bibset).
3331 See ccl/bib1 for an example.
3333 Fixes in ASN.1 compiler for C++ compatibility.
3335 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3336 and "op_or" to avoid conflict with C++.
3338 Fixed problem with GNU readline detection on Redhat 7.0.
3340 Added step-size for Scan backend handler.
3342 Fixed bug that made the frontend server crash when no attribute
3343 set was specified for scan.
3345 Front-end server automatically switches to original working directory
3346 when installed as an NT service. Previously -w had to be specified to
3349 Added extended attributes for retrieval module (data1), so that data1
3350 records carry d1_readXML/SGML attributes. d1_read also supports
3351 null-data rules ( <tag/>)
3353 On UNIX when POSIX threads are available, a separate library libyazthread
3354 is created. Programmers should link with that library and the yaz library
3355 when using threads. The reason for the split was that some applications
3356 on Linux, such as Apache, doesn't work well when using shared objects that
3359 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3360 (or any frontend server) in SSL mode by specifying ssl: followed by
3361 address. Only tested on UNIX.
3363 Added feature for CCL module. Virtual structure s=al or s=ol generates
3364 and-list and or-list respectively instead of phrase search.
3368 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3369 log_mask_str. This was done to avoid name conflicts with other libraries
3370 (such as other PHP extensions).
3372 Added raw OID member for preferred record syntax (request_format_raw)
3373 and returned record syntax (output_format_raw) for backend fetch method.
3375 Config file yaz-config now accepts options so that it returns specific
3376 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3378 Shared library support for UNIX using GNU libtool.
3380 * Modified backend interface. Request/Response struct's replaced by
3381 one read/write C struct. For example bend_fetchrequest and
3382 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3383 Every handler - even search has to be registered in bend_init
3384 handler. This means that the YAZ library no longer refers to
3385 external functions and it makes it possible to make the whole
3386 thing a single DLL/SO.
3388 Added Segment handler for backend server.
3390 Added Zmbol/Zebra administrative functions to YAZ client.
3392 Threaded frontend server on UNIX (when POSIX Threads are available).
3393 Starting the server with option -T enables multi-threading.
3397 Added configure option --enable-comp/disable-comp to control use
3398 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3399 located in sub directory asn.
3401 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3402 in ${exec_prefix}/bin along with the other programs yaz-client and
3405 GNU automake used to maintain makefiles.
3407 Added several OID's.
3409 Changed retrieval module so that we can load records with no abstract
3410 syntax defined. Tagpaths in these records are fully composed of string
3413 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3417 On UNIX, the generated makefile now supports a proper 'make install'.
3418 The prefix can be set via GNU configure to set the install location
3419 (default is /usr/local).
3421 * YAZ programs client and ztest were renamed to yaz-client and
3422 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3423 locations, such as /usr/bin,/usr/local/bin,etc.
3425 * YAZ Header files were moved from include to include/yaz. YAZ Header
3426 files are referred to as include <yaz/log.h> rather than <log.h>.
3427 The YAZ include path (-I ..) is therefore the same as before. Programmers
3428 should update their #include statements or use -Ipath/include/yaz
3429 instead. The main motivation for doing this change is that YAZ header files
3430 can be installed in "standard" locations /usr/include,/usr/local/include
3431 without introducing conflicts, since ALL YAZ header files are stored
3432 in subdirectory yaz (under /usr/include for example).
3434 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3435 rather than project/workspace files. We switched because project files
3436 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3439 Changed name of logging function, logf, to yaz_log, to prevent name
3440 clash with some math-log functions. The YAZ header log.h defines logf
3441 to yaz_log (#define) so there should be no incompatibilities by this
3444 Added bend_start/bend_stop handlers for server. These handler are
3445 called on start/stop of server. For windows they are called whenever
3446 a service is started/stopped.
3448 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3449 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3450 in util/yc.tcl. The auto-generated C code structures are, in a few
3451 cases, incompatible with the old decoders. There are differences in the
3452 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3453 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3454 The preprocessor variable ASN_COMPILED is defined when the compiled
3455 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3456 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3457 wish to use the old encoders/decoders you can specify --disable-yc
3460 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3461 version so that it supports both new - and old version of DB Update
3463 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3464 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3465 change. The name parameter can be set to 0 in which no name is specified
3466 for the construction. The macros odr_implicit and odr_explicit sets name
3467 parameter to zero for the construction involved. New macros
3468 odr_implicit_tag and odr_explicit_tag are similar to the others,
3469 except that a name parameter is added. For programmers' that don't use
3470 ODR they probably only need to change the call to z_APDU and z_External.
3472 Added access control facility by interfacing the TCP wrapper library.
3473 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3474 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3475 name of the daemon and enables the access control as specified in
3476 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3478 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3479 den Dool <H.M.vdnDool@kub.nl>.
3481 Added reference ID parameter to most functions in server API - refer
3482 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3484 Changed name of ccl library to libccl.a (was ccl.a).
3486 Fixed bug in decoder for Explain (Category TargetInfo).
3488 Added support for GNU readline in client. Thanks to Jacob Poulsen
3489 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3491 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3492 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3493 IMPLEMENTATION! This change was made to the development version before
3494 the ZIG decided to retract the amendment. If any users MUST be
3495 compatible with the original Update definition, PLEASE CONTACT US, and
3496 we will include a separate definition corresponding to the old Update
3497 ES. Note that because of the change to the ASN.1 of the
3498 TaskPackageRecordStructure we cannot define a single structure that
3499 will support both versions.
3501 * Added const modifier to buffer parameter for some ODR/BER encoding
3502 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3503 completeWAIS, odr_dumpBER.
3505 Fixed bug in client.c which caused a crash when a scanResponse didn't
3506 contain positionOfTerm.
3508 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3509 * will cause an error in a client if a non-YAZ target sends both a
3510 * list of Scan entries and non-surrogate diagnostics.
3512 Retrieval module enhancements. Tag sets may be typed in the reference
3513 to it. From the .abs-file the "tagset" directive takes a third optional
3514 integer type for the tag set referenced. From a .tag-file the "include"
3515 directive takes a third optional type as well. The old "type" directive
3516 in the tag set itself is still recognized but acts as the default type
3519 Backend interface change. Individual Scan terms returned from bend_scan
3520 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3521 in include/backend.h.
3523 Retrieval module enhancements. Multiple tag sets and attribute sets may
3524 be specified in abstract syntax specs. Revised the error/warning for
3525 logging messages reported by the retrieval module when reading the
3528 Object Identifier system (oid_..) changed. The API is backwards
3529 compatible but the oid-routines now allocates new OID's when needed.
3530 Raw OID's may be specified in oid_getvalbyname.
3532 YAZ now uses GNU configure to generate Makefile(s).
3534 * Minor changes in some of the member names of DeleteResultSetRequest and
3535 DeleteResultSetResponse. See include/proto.h.
3537 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3538 and added member 'languages' in TargetInfo (which was missing).
3540 Changed the way attribute sets are handled in the retrieval
3541 module. These are now cached, just like the abstract syntaxes
3544 Changed YAZ so that it links with compiled ASN.1.
3546 Added Explain-schema definitions and mapping routines. The following
3547 Explain categories have been implemented: AttributeDetails,
3548 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3550 Fixed minor bug in Windows version of Server Library.
3552 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3554 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3556 Added EXTERNAL: UNIverse Resource Report (non-standard).
3558 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3559 ENUMERATED and SET OF.
3561 * Added 'const' to some of the char pointer arguments for the
3562 functions, data1_read_node, data1_getelementbytagname,
3563 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3566 Fixed bug in data1_insert_taggeddata - the last_child member of
3567 parent wasn't initialised.
3569 * Changed data1_read_record and data1_read_node so that the supplied
3570 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3571 doesn't refer to any parts of the "SGML"-buffer.
3573 Fixed bug in server library (Windows version of statserv_remove).
3575 * Changed code so that it compiles as C++. The type definition
3576 of Odr_fun which is a member of Odr_arm was changed. The result is,
3577 that an explicit typecast is needed for the fun pointer when
3578 using Odr_arm - as in:
3579 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3581 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3583 Implemented the new structured date and time definition as approved
3584 by the ZIG. Added schemaId element to the specificTag in Espec-1
3585 (also approved at the last ZIG). Thanks to RVDM.
3587 Added some Object identifiers (RVDM).
3589 Changed the Update Extended Service (RVDM).
3591 Added command "refid" to client which specifies referenceId for
3592 the following requests.
3594 Implemented extended service handling for server. See ztest.c
3595 for an example as well as backend.h. New handlers are registerd
3596 in the Init handler.
3598 * Changed interface for sort in server.
3600 Added new members to statserv_options_block. It allows a server
3601 to read options from another source than just the command line. Thanks
3602 to Charles Woodfield.
3604 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3605 renamed to zboolean. Some C++ compilers complained about the name.
3607 Minor changes to gils.abs. Added index 's' (sort) on title
3608 and date/time-last-modified.
3610 --- 1.4pl2 1998/1/30
3612 Fixed bug in server library regarding inetd mode (-i). This bug
3613 was introduced by release 1.4.
3615 --- 1.4pl1 1998/1/29
3617 Added sort facility in client and backend server interface.
3619 Fixed problem with dependencies in Makefile(s).
3621 Fixed bugs for encoders/decoders of extended services and
3624 Implemented sub-tree feature for schemas. Sub-trees are
3625 referenced in *.abs-files. See explain.abs for an example
3626 of the use of this feature.
3628 Modified bib1.att; local attributes for ANY didn't include
3629 ANY itself (only affects use of the retrieval module).
3631 Fixed bug in plain SGML reader in function data1_read_node:
3632 tags with prefix "var" was incorrectly interpreted as variants.
3634 Added feature "sub-schemas" to enable references to - and definitions
3635 of - group of elements.
3637 * Removed member parent from type data1_element (in data1.h).
3639 Implemented function odr_nullval() that returns the value of
3642 * Removed member num_children from data1_node (in data1.h).
3644 Made NT service interface part of the server library. The
3645 function statserv_main uses the NT service when required and
3646 calls the statserv_start / statserv_close routines.
3648 Routine zget_SearchRequest and zget_PresentRequest fills
3649 resultSetName/Id member with "default" instead of "Default".
3651 Fixed memory leak in server. Request queue member wasn't freed.
3653 Fixed nmem_exit so that memory is freed.
3657 Revised the CCL parser utility to be thread safe.
3659 Added function, oid_ent_to_oid, to replace the function
3660 oid_getoidbyent, which is not thread safe.
3662 * Added nmem_init and nmem_exit to initialize and release
3663 NMEM resources. Function nmem_init should be called once in the
3664 initial thread before NMEM/ODR is used. statserv.c and client.c
3665 have been changed accordingly. The change was necessary to make
3666 NMEM thread safe. The NMEM memory pool is shared amongst threads
3667 in a process. Unix-based applications will still work fine without
3670 Added NT Services interface for the the Z39.50 (statserv) Server.
3671 Refer to the ztest.c source on the usage.
3673 Windows 95/NT port using MSVC5.0. Project files are included in the
3676 * Defined new 'global' handle for the retrieval (data1) system. The
3677 new handled, data1_handle, describes the state of the data1 system.
3678 This handle is passed as first argument to virtually all
3679 data1 related routines. The functions data1_create and data1_destroy
3680 creates and destroys a data1 handle respectively.
3682 Added ODR encode stream member to all backend request structures
3683 init, search, scan etc. This stream should be used to allocate all
3684 memory used for the response when thread safe operation is needed.
3686 Changed the comstack utility, cs_addstr, to be thread safe. The
3687 returned hostname string returned by the function is now part the
3690 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3691 function. The cs_straddr takes a COMSTACK handle as argument, so this
3692 function must be used after cs_create and before bind/connect.
3693 This function is thread safe.
3695 Moved test server to 'ztest' directory - generic server code still
3696 in 'server' directory.
3698 Made prefix query (pquery.c) utility thread safe.
3700 Added new function modifier YAZ_EXPORT to 'export' public DLL
3701 functions when using windows (see include/yconfig.h).
3703 Added definitions to the OID database (util/oid.c) (RVDM).
3705 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3707 Added call to ccl_rpn_delete in client program.
3709 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3710 release of RPN structure.
3712 Added support for C++, headers uses extern "C" for public definitions.
3713 With input from RVDM.
3715 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3716 Thanks to Ronald van der Meer (RVDM).
3718 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3720 Added support for private extensions to the OID database
3721 (oid_setprivateoids()). Thanks to RVDM.
3723 Added optional, physical ANY (key replication)
3725 Fixed null-reference problem in GRS-1 output filter.
3727 Proximity operator added to Prefix Query Format (PQF).
3729 In test client command "base" accepts multiple databases.
3731 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3735 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3737 Smallish bug-fixes in the new encoders/decoders (explain).
3739 Bug fixed in DeleteRequest.
3741 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3743 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3745 Added SOIF syntax (using private OID for now) to retrieval module and client.
3747 Added Update extended service.
3749 Added SearchResult-1 additional info structure.
3751 Added optional CCL (ISO8777) interpreter as separate module. Available
3754 --- 1.2 1996/6/10 (1st anniversary release)
3756 Added Summary record syntax. Lightly tested.
3758 Added OPAC record syntax. Untested.
3760 Added ResourceReport service encoders/decoders. Untested.
3762 Fixed bug in z_Unit - wrong tagging on unitSystem.
3764 Fixed bug in the DiagRecs decoder.
3766 Added options for max PDU size and session timeout to frontend-server.
3768 Added documentation of query-language parsers and other supporting utilities.
3770 [frontend-server] Added Attribute set to the bend_scanrequest API.
3772 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3773 surrogate diagnostics were generated.
3775 [retrieval] Allow multiple local values for attribute.
3777 [retrieval] Allow multiple attributes per element in .abs files. index type.
3779 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3781 --- 1.1pl2 1996/4/10
3783 Minor changes, mostly specific to Zebra's requirements (retrieval)
3787 Repaired bug in frontend server when running multiple listening
3788 endpoints in dynamic mode.
3790 z_External() now won't break if a known, ASN.1 value comes encapsulated
3791 in an octet-string. The value will pass through unmodified in an Odr_oct.
3793 Added a bit of code to the demo client to decode & display
3794 ASN.1-structured records represented in the octet-aligned branch of
3795 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3797 Added z_ext_getentbyref() to the ASN module. Doc updated.
3799 * Completed the SCAN definition in the ASN module. This may break SCAN
3800 code based on older YAZ-versions at compile-time. The fix is easy -
3803 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3804 under the SCAN definition. Remember to initialize this, server-people.
3806 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3807 that this does not extend to ODR and ASN.
3809 Comstack allows insertion of established socket (primarily for
3810 inetd-operation of servers). Doc updated.
3812 Front-end server can now start from the inetd in TCP mode. Doc
3815 --- 1.0pl4 1996/1/24
3819 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3820 the rank and record number.
3822 Adjustments to the frontend server.
3824 Fixed diagnostic BER dumper. It ignored the file argument.
3828 Various changes to retrieval module.
3830 Changed the union discriminators of the protocol files from enums to
3831 ints paired with #defines.
3833 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3836 *Changed operator in the RPN structure to 'roperator', again to avoid a
3839 Fixed problems in Explain decoders/encoders.
3841 --- 1.0pl2 1995/12/6
3843 Memory bug in log module fixed.
3845 --- 1.0pl1 1995/12/5
3847 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3849 Bug in Explain DatabaseInfo module fixed.
3851 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3855 The shift to v1.0 signals that we now consider the *core* functionality
3856 of YAZ reasonably stable (the core being more or less equivalent to
3857 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3858 tested (Explain not at all - though that will happen soonish).
3860 Minor changes to code to support Windows port.
3862 Various minor changes after we're getting to use GRS-1 & co. more.
3864 Added Espec-1 format.
3866 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3867 of the protocol and it cannot be selected when encoding (maps into 'string'
3868 when decoding). Needed to talk to some servers.
3870 Demo client can request simple element set names.
3872 Added Diagnostic Format encoders/decoders.
3874 Added simple Close handling to frontend server (no hooks for resource
3875 reporting yet), and demonstration client.
3877 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3879 --- 1.0b3 1995/08/24
3881 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3882 handled incorrectly when records were requested in the searchResponse. This
3883 will only affect you if you use the frontend-server.
3885 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3886 Test-client will ask for and print GRS1. Ztest will return dummy records
3889 Added Explain encoders/decoders to the service-level API. Untested.
3891 Added Extended Services: Item Order encoders and decoders to the Service-
3892 level API. Untested. We could use a recent copy of the pertinent bits
3893 of the ILL protocol to add those bits.
3895 Added diagnostic format 1 encoders/decoders to the service-level API.
3898 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3899 odr_cons.c, which causes a more correct output.
3901 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3902 was always set to 0 when no records were requested in the searchRequest.
3904 * Added better external-handling. This shouldn't harm old code that
3905 *encodes* externals. It can break code that looks for a
3906 'single-ASN1-type' representation, since those types that are known
3907 are now decoded immediately. Look at the SUTRS sample code in
3908 seshigh.c and client.c. Documentation updated.
3910 Handling of structured records in bend_fetchresponse. Length -1 marks
3911 structured record, type is deduced from format field.
3913 --- 1.0b2 1995/06/27
3914 Fairly quick maintenance release to add SUTRS support.
3916 Fixed handling of SUTRS records in the demonstration client.
3918 * Added format field to the bend_fetchrequest and bend_fetchresponce
3919 structures of the backend API (frontend server). When the record is
3920 returned, the value of the format field is mapped to an OID. The
3921 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3922 of the record. The special value VAL_NONE in the bend_request means
3923 that no specific format was requested by the client. Documentation
3924 updated accordingly. Test server (ztest) will return a fixed dummy
3925 SUTRS record if your client requests SUTRS.
3927 Documentation updated accordingly.
3929 You can now set external libraries and RANLIB support in the top-level
3933 First public release.
