3 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
7 Build YAZ for Ubuntu Oneiric.
9 CCL: allow parantheses for proximity operands. For example CCL query
10 (a) % (b) is now allowed.
12 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
13 marked dead, rather then being destroyed. If not, the session memory is
14 being free'd before the search/scan handler is finished. Also destroy
15 'request' memory in request_release rather than in various places,
16 which resulted in leaks from time to time.
20 cql_sortby_to_sortkeys: honor sort prefix.
22 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
23 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
24 The rpn2cql family of functions now always returns quoted CQL terms.
26 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
30 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
31 sequence is treated as one. For example, &&a=b&&&c& is identical to
36 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
37 APDUs for a connection to a WRBUF.
41 Fix cql_sortby_to_sortkeys. Completely broken before.
43 Make CCL's @truncation work again.
47 New ZOOM connection setting: tproxy. It's like proxy, but does not
48 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
49 to set resolved address + port for a connection outside ZOOM itself.
51 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
55 Fix uninitialized variable in Solr spell support (could cause SEGV
56 for SRU response decoding).
58 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
59 back-end's addinfo through into the ZOOM response addinfo.
61 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
62 they are separated by a colon and a space rather than simply
67 Add support for Solr spell-checking/suggestions through ZOOM.
68 If a Solr target has been configured correctly for spelling-checking
69 and suggestions, these will now be returned on the ResultSet option
70 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
74 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
75 with a flag whether to substitute escape sequences or not.
79 Fix nmem_strsplit_escape to substitute escape char properly.
81 New option for zoomsh -e , which makes it abort on first error and
82 return process exit code to indicate success/failure.
84 YAZ options utility supports special option -- which makes all it treat
85 all following arguments as non-options.
89 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
90 searched if absolute filename is given.
92 Fix conv_xslt() error-reporting when stylesheet is not found.
93 (The value of fullpath is meaningless in this situation.)
97 Fix problem in CQL sort node creation: un-initialized memory.
99 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
100 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
101 CQL sortby depending on whether Type-1 or CQL is actually sent to the
104 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
105 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
107 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
108 will make it possible to use both single-character mask (#) and wildcard (?)
109 in CCL . Throw diagnostic for left truncation because that is not supported
112 --- 4.2.13 2011/09/01
114 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
115 cases using escapes (\-sequences) and masking.
117 PQF parse fix: A trailing backslash followed by end-of-string (\0)
118 would result in a read one byte beyond string.
120 rpn2ccl may use Z39.50 masking for terms (t=z).
122 ICU check fix. Don't include library -lCrun on Solaris, unless present.
124 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
125 not --cppflags (which seeems like an error in icu-config).
127 --- 4.2.12 2011/08/27 RPM package only
129 cql2ccl: fix conversion of terms: operator characters were not
132 --- 4.2.11 2011/08/25 RPM package only
134 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
135 CCL parser will map both # and ? to their regular expression
136 quivalents (. and .*).
138 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
139 of reserved CQL characters.
141 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
142 is, so that they are passed through.
144 --- 4.2.10 2011/08/24
146 ZOOM SRU mode: more aggressive re-connect.
148 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
149 made available as a utility function, declared in <yaz/logrpn.h>
151 rpn2cql_structure() supports proximity nodes (except that the Type-1
152 proximity node's "exclusion" binary is ignored, as there is no way to
153 express that in CQL). Fixes bug #4564.
157 Fix SEGV that could occur if set command of zoomsh was given without
158 value (2nd argument).
160 Fix SEGV that could occur if unsupported transport was given for
161 COMSTACK - say https (when SSL was unavailable).
163 Build yaz-url on Windows too.
167 New utility to get web content. Header is url.h. A command line tool
168 yaz-url is part of the distribution and packages.
170 Fixes for SSL COMSTACK (when gnutls is in use).
172 New functions yaz_base64{encode,decode}. Header is base64.h.
176 ZOOM C includes HTTP response buffer as additional info if it fails
177 to decode the SRU response.
179 Make wrbuf_json_puts available.
183 zoom: throw diagnostic for invalid value for option "sru". Before a
184 bad SRU request was sent.
186 Adding new utility wrbuf_vp_puts.
188 Add cclxmlconfig.obj to win/makefile. It was missing completely.
192 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
193 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
194 redirect was used at the same time.
196 MARC line mode decoding: be less picky about length given - first
197 5 digits of header that is.
199 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
201 Changes to decoding of SRU records: a record with recordPacking=xml is
202 modified with a new root element <yaz_record> if the recordData contains
203 multiple children elements. This is to make the record XML parseable
206 RPN to SOLR conversion: encode special characters.
208 Generic Frontend Server: fix uinitialized member, stepSize.
212 Fix a bug in SRU decoding of records.. The database records stored
213 had un-initialized memory, but it would only be seen with yaz_record_render
214 and type_spec="ext" .
216 Fix a bug in ccl_qual_dup introduced in 4.2.3.
220 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
224 Add new utilities to convert from CQL to CCL . These utilities have
225 prefix cql_to_ccl defined in cql.h.
227 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
228 lead to memory heap corruptions when ICU utilities were in use.
232 Make compilation work without Libxml2.
234 yaz-client: remove redundant blanks in display of searchResult-1 term
239 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
240 resulting CQL node (tree) in a new node CQL_NODE_SORT.
242 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
243 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
244 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
245 Note that the CQL sortby spec is only converted when the GFS is already
246 converting from CQL to RPN (cql2rpn element).
248 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
249 specify whether to collapse delimitors or not. The existing nmem_strsplit
250 do collapse (collapse parameter = 1).
252 Windows installer: For NSIS, set InstallDir depending on x86/x64.
254 Rename internal func yaz_use_attribute_create. While non-static, this
255 function is not declared in a public header.
259 Add -lCrun when linking with ICU on Solaris.
261 More quicks character set conversions for OPAC records.
265 fix problem with record_render: records were converted (character set
266 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
270 SRU: add methods for handling DADS SRU-proxy facets.
272 Separate OPAC record character set for ZOOM_record. yaz_record_render
273 allows a character set given as charset=from/opacfrom,to where 'from' is
274 the character set of a bibliographic record, 'opacfrom' is character set
275 of OPAC record and 'to' is the target character set.
279 yaz-client: show may XML format records. Command show followed by 'format'
280 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
283 src/stemmer.c: Avoid using unnamed union. It is not supported by some
286 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
289 Update yaz.spec to operate on both SLES11 / Centos 5.5.
291 RPM: Release includes 'indexdata' name. Use indexdata in release name so
292 this package can be distinguished from other vendors.
294 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
295 as determined by configure
297 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
299 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
300 returns no error and no record, the present request is considered
301 partial (only a subset of the records could be returned by backend), and
302 so it is appropriate to set Present Status to partial-4.
306 Move yaz-config man pages to section 1.
308 More documentation about SOLR.
310 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
311 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
312 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
313 peers on some Linux systems. However, in general that does not work
314 so YAZ can not rely on that to work. Debian changed behavior in this
315 respect from Debian lenny to Debian squeeze (still testing as of Oct
317 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
319 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
323 Fix yaz-config output: echo_source not set correctly by configure.
327 SOLR WebService support for yaz-client and ZOOM.
329 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
331 --- 4.0.12 2010/08/17
333 Z39.50 facet support. Facet specifications are passed for search in
334 other-information with ASN.1 as defined in facet.asn and OID
335 .10.1000.81.5 . Facets are expressed as an Attribute list as known
336 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
337 3 is limit (number of entries to get in response). yaz-ztest returns
338 dummy facets if a client asks for them.
340 --- 4.0.11 2010/07/09
342 CCL fixes: bug 2895 and bug 3539.
344 GR1-display: add comma in display - was removed by mistake in
347 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
349 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
351 --- 4.0.10 2010/06/18
353 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
354 result set from a connection. The result set will be on its own
355 thereafter; no operations on it will perform retrievals from a target.
356 Only cached copies are returned.
358 ZOOM C:fix case for HTTP servers responding with Connection:close.
359 Ensure that if there is a current task it is resumed (like fetching
360 more records in a result set) . Bug #3484.
362 PQF parser: use odr_atoi for Odr_int (not atoi)
364 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
365 values that contain any non-digits are treated as string attributes
366 (previously decoding only checked for leading character ([0-9]). PQF
367 encoding: attribute string values are not surrounded by double-quotes.
371 New utility for managing threads - thread_create.h.
373 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
374 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
375 but YAZ' implementation do.
377 Fixes for yaz_cond-functions on Windows 7.
379 DLL export more symbols.
381 zoomsh: show record do NOT render opac.
383 Remove *.la files from Debian and RPM packages.
387 Debian package libyaz-dev depends on libgnutls-dev again (was
388 removed in YAZ 4.0.6, but due to Libtool it is still needed
389 even though yaz-config do not list libgnutls libs).
391 ZOOM: Use only one WRBUF for returning string results for
392 ZOOM_resultset. Reduces memory usage for ZOOM in general.
394 ZOOM: ZOOM_connection do not use a shared pointer to
395 ZOOM_resultset after ZOOM_resultset is destructed by
396 user. Reverts to YAZ 4.0.4 behavior.
400 record-conv: fix problem with at least one XSL conversion -
401 due to probably incorrect usage of XML XSL documents.
405 Fix yaz-config for static mode and the use of SSL (gnutls).
409 Forward decl timeval struct in mutex.h and gettimeofday.h.
411 yaz-config: fix 'static' mode linking.
415 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
416 are wrappers for pthreads or Windows. For Windows these are put in
417 a separate DLL: yaz_cond4.
419 libyaz.la (whole source) is compiled with thread. If thread support
420 is enabled enabled, all source of YAZ is compiled with treading support.
421 This allows core utilities such as yaz_log to use thread facilities.
422 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
423 thread utilities. This commit moves mutex utilities (mutex.c) from
424 libyaz_server.la to libyaz.la.
426 yaz-json-parse displays leading text until error.
430 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
431 patch from Giannis Kosmas.
433 SRU: no longer URL encode SRU database. The URL for an SRU server is
434 a URL and such is alreeady encoded - at least when given with leading
435 http:// or https://. This reverts behavior to YAZ 3.0.50.
437 Support for new MARC XML notation TurboMARC which like MARCXML is a
438 complete representation of MARC/ISO2709.. This one, however, is more
439 compact and allows for faster processing with XSLT. TurboMARC can be
440 used in the marcdisp.h API, from the yaz-marcdump utility and from
443 yaz-ztest can be configured - via the database - to perform certain
444 delays when it performs operations search, present and single record
445 fetch. This allows testers to make yaz-ztest act as a real or even slow
446 Z39.50 server. Refer to the yaz-ztest man pages for details.
450 wrbuf_destroy allows NULL WRBUF passed to it.
452 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
454 Add ZOOM_connection_close.
456 No fixed size buffers for ZOOM shell - bug #3257.
458 tstodr: make it work on s390 platform.
460 New icu iterator-functions. The new icu_iter-functions makes it possible
461 to use ICU chains from many threads.
463 yaz-client: better syntax check for show command.
467 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
470 New simple local-file XML include facility which allows file glob-patterns.
471 Refer to yaz/xml_include.h.
473 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
476 ZOOM_record_get supports new parameter "format" which makes it format XML
479 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
480 JSONText in ECMA-262) is JSONValue, not JSONObject.
484 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
485 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
487 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
488 POSIX/Unix builds .so with major version 4.
490 Remove old LOG_-defines from log.h. They have been obsolete and
491 undefined by default for the last 5 years.
493 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
495 GFS: Remove socket (int *fd) from search_rr handler. The socket
496 descriptor ptr is a facility that allowed a search handler to supply
497 a socket which would serve as a callback - when search was complete.
498 This facility has now been in use for years.
500 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
501 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
502 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
503 returns 'const char *' rather than 'char *. The returned string is
504 read-only and should not be modified by applications. COMSTACK cs_close is
505 now a void function - it no longer returns int. No applications check for
506 the value and the implementations has always returned 0.
508 ZOOM: use size_t for scan hit counts and str size. Functions
509 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
510 occ (hit count) and len (string length) are now of type size_t pointer
511 rather than int pointer. This is to be able to represent large hit counts
512 and to also just to use the proper type for string length (strlen result).
514 New JSON parser. Refer to include/yaz/json.h .
516 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
517 Used to be int in some cases. Many wrbuf_-functions used to return an int
518 indicating some length.. These return values were never used. And so they
521 ODR: odr_malloc, odr_total now takes size_t for size.
523 clone_z_type: fix leak; occurred for encoding failures.
525 --- 3.0.52 2009/12/03
527 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
528 bug was introduced in 3.0.51.
530 --- 3.0.51 2009/12/02
532 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
534 tcpip comstack: fix leak for getaddrinfo.
536 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
537 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
538 Decoding of SRU "path" database is performed by private function
539 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
540 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
542 yaz-client: honor base command for SRU. Change when database setting
543 is applied for SRU and ensure it is kept when a connection is reset.
544 Change also the way errors are displayed or SRU (decoding of packages).
546 --- 3.0.50 2009/11/02
548 Add support for extra request / response data for SRU codecs and GFS.
549 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
550 for extra data response buffer and length. For the GFS, both request
551 and response data (XML) is carried in extra_args and extra_response_data
552 for the search handler. Patch by Ko van der Sloot.
554 ZOOM: For queries that cannot be converted to the specified rpnCharset,
555 ZOOM now returns a diagnostic on the client-side ('invalid query' /
556 10010). This fixes bug #2113.
558 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
559 cmdfile included a 'quit' command that would result in a memory violation.
561 --- 3.0.49 2009/10/01
563 Make a number of functions defined in xmlquery.c static. These have
564 never been declared in a public header file (yaz/xmlquery.h) and was
565 made public by mistake.
567 Improve speed of character conversions (iconv utilities). This makes
568 conversions from MARC-8 faster.
570 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
571 unless type desired is "raw". This will prevent type "xml" from
572 returning ISO2709 .. Which obviously can not be XML parsed.
574 Fix memory leak in ZOOM that would occur if option apdulog was used
575 on a re-used connection.
577 Frontend server logs HTTP requests.
579 Frontend server now sends Z39.50 close when it times out (sesssion has
580 been idle for too long). Versions 2.0.30 and earlier also sent close.
581 But due to a mistake this was disabled in all versions after that, i.e.
582 the server would just close the socket immediately.
584 yaz-client emits a better message when receiving an unrecognised
585 userInformationField.
587 Skip zero-length subfields when decoding ISO2709. This rare case happens
588 if a record has two FS characters in a sequence. Without this patch
589 there would be a reference beyond char array in using_code_len fragments
592 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
594 --- 3.0.48 2009/08/28
596 The show command offered by the zoomsh command now takes a 3d optional
597 parameter type which is what is passed to ZOOM_record. If the type
598 argument is omitted, "render" is used.
600 RPN to CQL conv may use USE string attributes (bug #2978).
602 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
604 --- 3.0.47 2009/07/08
606 Function yaz_xml2query allows a diagnostic element in the PQF XML
607 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
608 code and additional info respectively.
610 The BER BOOLEAN is now the integral type Odr_bool which still happens
611 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
612 typedef'd to Odr_int. This is still an integral 'int', but it may be
613 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
614 ASN-1 compiler as well as programs has been updated to use the new types.
616 --- 3.0.46 2009/06/08
618 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
619 only the bibliographic record was rendered. For type=opac, an OPAC
620 record is only returned if it is present.
622 iconv: small fix for encoding of advancegreek.
624 yaz-client: avoid double display of SRU/SRW records (bug #2798).
626 yaz-client: option auto_reconnect=on really reconnects.
628 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
630 server: avoid null ptr ref for for yaz_poll errors.
632 build: fix RPM build for RHEL 5.3.
634 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
636 --- 3.0.45 2009/03/31
638 Fixed bug #2709: TCP connect returns Invalid argument.
640 Fixed compilation for mingw.
642 Honor charset for raw records (ZOOM_record_get).
644 Fixed use of errno for threaded mode that was seen on Solaris 10.
646 Fixed argument passing with blanks in value for Windows Service.
648 Disable YAZ' own log rotate by default (no 1 GB limit).
649 The variable l_max_size which specifies the log file limit is set to 0
650 (DISABLED): This is due to the fact that YAZ is most often deployed using
651 logrotate. Also YAZ can not perform log rotate because of unsufficient
652 permissions (setuid).
654 --- 3.0.44 2009/02/17
656 List supported encodings in man page for yaz-iconv.
658 Fixed missing SSL libs for --libs output
660 Re-established OID record syntax application-xml. Nobody should use it
661 but we don't want to change soname because of this symbol being absent.
663 --- 3.0.42 2009/02/02
665 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
667 Added member named_result_sets for init handler struct for the GFS. This
668 allows a server to disable named result sets.
670 Removed OID record syntax application-xml.
672 Added support for rule-based transliterator for ICU wrapper of YAZ.
674 Fixed bug #1902: yaz-icu XML output.
676 Make YAZ checks Emacs friendly.
678 BITSTRING value shows value. Bug #2346.
680 ISO2709 decoding: skip control characters from indicator data.
682 Omit sort key by default in yaz-icu's output.
684 Allow combined single char options (again) for YAZ' options function.
686 Utility yaz-marcdump got option to display YAZ version (-V).
688 Allow YAZ to use ICU 3.4.
690 Added new ICU test case which illustrates removal of diacritics.
692 --- 3.0.41 2008/12/29
694 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
696 --- 3.0.40 2008/12/29
698 For configure, using option --without-xml2 also disables Libxslt/Libexslt
701 Fixed bug #2352: yaz-marcdump crashes for certain record.
703 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
705 Added support for Danmarc2 to UTF-8 conversion.
707 Added support for ISO5426 to UTF-8 conversion.
709 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
710 implementation version.
712 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
714 --- 3.0.38 2008/11/10
716 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
717 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
719 ZOOM C now interprets databaseName option for ZOOM connection as path
722 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
724 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
726 Dummy Libxml2 types no longer defined in headers of YAZ'.
728 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
731 --- 3.0.36 2008/09/26
733 Various ODR chapter fixes.
735 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
737 Added missing source for Windows compilation, mutex.c.
739 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
741 For SRU connections in ZOOM all records up to "count" are now fetched.
743 Fixed crash in generic frontend server (and yaz-ztest) which occurred
744 in Windows due to bad error handling for Libxml2.
746 Added facility for sending arbitrary records (ASN.1 any) using
747 ZOOM C's Extended service update. Patch by Sam Reynolds.
749 New options for ZOOM C's connection, logapdu which makes ZOOM log
752 --- 3.0.34 2008/06/18
754 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
756 --- 3.0.32 2008/06/12
758 Fixed memory violation that could occur when decoding UTF-8. This bug
759 was only present in 3.0.30 of YAZ.
761 --- 3.0.30 2008/06/06
763 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
764 GNU TLS is used by default (if found).
766 yaz-ztest returns OPAC records if a client asks for OPAC.
768 Improved speed of MARC-8 encoding.
770 Added support for lossy and loss-less MARC-8 encoding.
772 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
774 Added new Windows Service wrapper (sc).
776 yaz-client's itemorder command may now send a file.
778 Fixed yaz-marcdump to allow the use of NS prefix for record element.
780 Added new function yaz_log_xml_errors.
782 Allow (but warn) unknown XML attributes in MARCXML parsing.
784 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
786 The UTF-8 to MARC-8 conversion now uses a different set of characters
787 for Greek symbols. Bug #2120.
789 --- 3.0.26 2008/02/21
791 Added yaz_daemon (daemon.h).
793 Fixed bug #2068: pkg-config trouble
795 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
797 --- 3.0.24 2008/01/28
799 Document --with-xml2 option.
801 Added OPAC XML XSD (etc/opacxml.xsd).
803 Allow glob mask for name attribute in retrieval element for the
804 generic frontend server's retrieval facility.
806 Changed yaz_poll_poll to return yaz_poll_except for all returned events
807 except POLLIN/POLLOUT.
809 Fixed error handling in cs_listen. Bug #2037.
811 --- 3.0.22 2008/01/20
813 Fixed version in yaz/yaz-version.h.
815 Fixed bug #2027: Crash when closing connection.
817 Changed configure so that ICU support is only enabled if only ICU
818 and Libxml2 is available (because the ICU chain is XML based).
820 --- 3.0.20 2008/01/15
822 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
823 is built. Only this DLL depends on the ICU runtime.
825 yaz-ziffy is no longer part of YAZ. It is distributed separately by
826 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
828 Changed license of CCL module to 'Revised BSD'. After consultation with
829 remaining members of the original EUROPAGATE consortium, we are re-issuing
830 the CCL module without a separate license. The software was developed by
831 Index Data as part of a research project. The special license was included
832 to help feed usage information back to the project consortium to support
833 project evaluation. At this time, the project consortium has long-since
834 disbanded, and the majority of the original principals have retired. At the
835 same time, we have significantly modified the software during the following
836 years, to the point where very practically no original code remains. To
837 simplify re-use of the software, we have contacted those members of the
838 consortium who could be reached, and agreed to re-issue the module as a
839 proper part of the YAZ package.
841 Tcl scripts uses /usr/bin/tclsh as preferred shell.
843 CQL closer to being version 1.2 compliant. CQL also allows free-form
844 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
847 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
848 bug could make Extended services handling crash in the ZOOM layer. This
849 bug was only present in YAZ 3.0.18.
851 --- 3.0.18 2007/12/19
853 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
856 yaz-marcdump reads and writes collection wrapped records.
858 Handle OPAC for record conversion module.
860 Fixes for ICU wrapper.
862 Allow ICU libs to be controlled with --with-icu .
864 --- 3.0.16 2007/11/12
866 Added yaz_poll which is a wrapper for select/poll. When poll is available
867 and non-buggy, it is used, by yaz_poll . This allows more than 1024
868 sockets to be in use.
870 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
871 functionality through an XML based configuration (ICU chain). This system
872 is useful for search facilities such as Pazpar2 and Zebra that needs to
873 perform tokenization of indexed material. The ICU code in a separate
874 library libyaz3_icu.a.
876 Added HTTP tunnel facility for COMSTACK, bug #1752.
877 This is a facility that allows a Web proxy, such as squid, to tunnel
878 Z39.50 traffic. This facility is "transparent" to must applications
879 using YAZ. It's enabled by using pseudo transport connect: followed by
880 the proxy address, followed by command, then follwed by he regular
881 "virtual" addresss. For example,
882 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
884 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
886 --- 3.0.14 2007/09/21
888 Fixed bad memory reference in ZOOM_record - cuased by member not being
889 initialized. This was a problem only in YAZ 3.0.12.
891 Fixed bug in conversion from MARC to XML: Non-XML characters in control
892 fields were not removed.
894 Changed the way C code is generated from codetables.xml. Made a MARC-8
895 conversion trie for each characterSet section rather than codeTable.
896 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
897 of codetables.xml from Larry Dixson, LOC. Bug #1464.
899 --- 3.0.12 2007/09/12
901 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
902 from ZOOM_record_error).
904 ZOOM C function ZOOM_record_get returns record schema for type="schema".
906 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
908 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
910 Better SRW-to-Bib-1 diagnostic mapping.
912 ZOOM C and yaz-client announces SRU version 1.2 by default.
914 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
917 Fixed in yaz_sru_decode to allow other version than 1.1.
919 --- 3.0.10 2007/08/22
921 Added support for SRU scan for ZOOM.
923 Added support for the use of the older versions or Extended Service
924 Update in ZOOM. To faciliate this, an option "updateVersion" may be
925 set to the version , 1=first, 2=second, 3=third. The third version is
926 what ZOOM C has used so far. And that, obviously, is the default.
928 Added support for CCL queries in Z39.50 queries sent to the GFS (and
929 therefore in Zebra and in SimpleServer-based applications). The new
930 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
931 qualifier file used to transform incoming CCL queries into Type-1 RPN,
932 which is passed into the back-end search callback function.
934 Added support for HTTP Basic authentication in clients: the SRU/W
935 codec encodes the username/password elements of the PDU structure
936 appropriately, and these may be set using the "user" and "password"
937 options in ZOOM-C applications (the same options that are used for
938 Z39.50 authentication).
942 Fixed bug #1208: SSL appears to be broken in ZOOM.
944 Fixed bug #1206: Libxml2 include path weirdness.
946 Added oid_name_to_dotstring.
948 Allow elementSetName to be specified for ZOOM C record update.
950 Allow waitAction to be specified for ZOOM C based for Extended Services.
952 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
953 syntax OID. Bug introduced in YAZ 3 series.
955 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
959 Fixed bug #1157: yaz-client does not read .yazclientrc from current
960 directory. yaz-client now reads commands from file given by option -f
961 if specified; then tries to read .yazclientrc in current directory.
962 Failing that, it reads .yazclientrc from user's home directory.
964 Added support for correlationInfo Note and ID for Record Update via
967 Added yaz-client command querycharset which specifies character set for
968 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
969 (termListAndStartPoint).
971 Charset ISO5428:1984 is an alias for ISO5428-1984.
973 Implemented a way to perform scan in a result set using Z39.50. This
974 is achieved by attaching the result set name in the characterInfo
975 (type InternationalString) of OtherInformation in the Scan Request PDU.
976 The result set is identified in the otherinformation by the new OID:
977 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
978 This allows for scan in result set and faceted search . Zebra did some
979 of this in the APT term using attribute type 8 and value being result
980 set. Using the OtherInformation approach for this is cleaner and easier
981 to work with in proxies and the like. This facility can be used in
982 yaz-client using new command setscan which takes a result set as first
983 argument, start position (APT) as second.
985 Changed decoding of SRU XML packed records to deal with servers that
986 have recordData with XML data with multiple root nodes. Also make
987 comparison for recordPacking case insensitive. Again, one server
988 returns "XML" where others return "xml".
990 For SRU responses allow Content-Type application/xml as well as text/xml.
994 Fixed bug in character set conversion of BER strings. Bug introduced
999 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1001 For OID class, use oid_class consistently.
1003 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1006 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1007 character set for bibliographic information interchange". By Giannis Kosmas.
1009 Added documentation on new OID API.
1011 --- 3.0.0 2007/05/02
1013 Changes to generic frontend server interface: added new member
1014 'query_charset' for bend_initrequest structure. A backend init handler
1015 should set this member to its native character set for query terms.
1016 When defined, the frontend server logic will announce this character set
1017 to a client if the negotiationModel bit is set by the client. All server
1018 implementors are encouraged to specify this. If a backend server does not
1019 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1021 Added CCL utility to remove terms (stop words) from resulting RPN
1022 tree. This is handled by functions with prefix ccl_stop_words_ .
1024 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1025 terms in RPN queries.
1027 Clean-up the CCL API. Moved some internal structures from ccl.h to
1028 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1029 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1030 This is replaced by ccl_parser_find_str which takes a string instead.
1032 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1033 libyaz.la is the core of YAZ except the generic frontend server and
1034 does not depend on POSIX threads anymore. libyaz_server.la is the
1035 generic frontend server facilities and uses POSIX thread functionality
1036 if available. The libyaz.la no longer depends on POSIX threads because
1037 the number of global structures is limited. NMEM no longer re-uses blocks
1038 between threads ; it simply free's memory immediately but allocates in
1039 "large" chunks as usual. We don't expect any performance penalties
1040 because of this. The yaz_log system is still using a global log_level so
1041 caution must be taken when modifying it with yaz_log_init_.. +
1042 yaz_log_mask_str. This, however, should not cause any trouble because
1043 these functions are called during initialization of application code
1044 anyway. `yaz-config --libs server` returns libs for server applications;
1045 `yaz-config --libs` returns libs for non-server applications.
1047 New OID database - with public definitions in oid_db.h. Removed old OID
1048 database including the head oid.h and definitions such as enum oid_value
1049 and struct oident. The new OID database uses the same string names as
1050 before but the 'protocol' is gone. There are now only two representations
1051 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1052 converts from string to OID; functions with prefix yaz_oid_to_string
1053 converts the other way.
1055 Change to emit_term() in CQL-to-PQF query translation: when a term has
1056 the /regexp relation modifier, do not process it for leading and
1057 trailing "^" and "*", which have quite different meanings in regular
1060 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1061 write handlers no longer carries a 'last' parameter. This will make
1062 yaz_iconv flush "less" characters. A flush is performed by call to
1063 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1065 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1066 removed, because function yaz_query_to_wrbuf does the same.
1068 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1069 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1071 Deprecated MARC utility functions removed.
1073 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1076 Branch split: YAZ_2_1_55_branch
1078 --- 2.1.54 2007/03/16
1080 Fix to ZOOM-C so that transparent reconnection is properly handled on
1081 connections that are in asynchronous mode.
1083 Fixed compilation on OpenBSD 4.0.
1085 Large strings in GRS-1 records are now properly displayed in yaz-client.
1087 Added character conversion support for "advancegreek"; based on patch from
1090 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1091 sequence is met. Before the error was not set so it would be unknown.
1093 Adjust yaz-marcdump MARC reader so that it skips until record separator
1096 --- 2.1.52 2007/03/07
1098 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1099 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1100 fd_set structure used as a bitmask for the FDs to be selected on.
1102 Using ACX_PTHREAD macro to check for POSIX threads.
1104 Fixed have-vsnprintf check.
1106 --- 2.1.50 2007/02/23
1108 Fixes for configure on BSD. Bug #900.
1110 Added snprintf/vsnprintf wrappers for systems that don't have
1111 limits (heavens forbid).
1113 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1114 created before all previous tasks were completed and removed from the
1115 task queue, the new task could be removed by a mistake.
1117 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1119 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1121 Fixed bug #832: Problem with MARC/charset in yaz-client.
1123 Fixed bug #668: save command line history for yaz-client.
1125 Fixed bug #830: pkg-config support.
1127 --- 2.1.48 2007/01/23
1129 Extended ZOOM result set options with two options that may be read by
1130 a client: resultSetStatus and presentStatus with values as specified for
1132 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1134 Fixed bug #827: Using SSL fails on Debian etch.
1136 Fixed bug #826: Weird looking chars for set of MARC records.
1138 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1139 that is treated as an ItemOrder with itemRequest being an XML document
1140 external. The value of "doc" is the content.
1142 Extended the GFS search facility. New member of bend_search_rr
1143 'estimated_hit_count' signals that hits is known to be an estmate
1144 (higher or lower than real hit count). New member 'partial_resultset'
1145 signals that the search was partial (hit count is lower or equal than
1146 real hit count). For Z39.50, the information is stored in resultSetStatus
1147 member of SearchResponse APDU. For SRU, the information is signalled
1148 via SRU diagnostic 59: "Result set created with valid partial results
1151 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1153 --- 2.1.46 2007/01/13
1155 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1157 Added ZOOM_connection_peek_event.
1159 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1160 the following new functions:
1161 ZOOM_event_nonblock, ZOOM_connection_process,
1162 ZOOM_connection_get_{socket,mask,timeout},
1163 ZOOM_connection_fire_event_{timeout,socket}.
1164 The existing blocking event handler, ZOOM_event, is a wrapper for the
1165 + blocking ZOOM_event_sys_{poll,select}.
1167 Implemented function ccl_xml_config which parses XML version of CCL
1168 configuration (bug #798).
1170 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1172 Added timings utility (yaz/timing.h)
1174 --- 2.1.44 2007/01/03
1176 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1179 Fixed bug #779: Rotation of apdu.log fails.
1181 Fixed for character set conversions:
1182 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1183 Honor G1 set in MARC-8 decoding.
1185 --- 2.1.42 2006/12/17
1187 Fixed bug #775: char conversion does not handle Alternative UTF-8
1190 Implemented function yaz_marc_read_line which parses MARC line format
1191 records. There is a wealth of formats out there. So far, this function
1192 reads line records produced by yaz_marc_write_line.
1194 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1195 more generic and easier to remember(!) options: -i format and -o format
1196 which specifies input format and output format respectively - where
1197 format is one of "marc", "marcxml", "line", "marcxchange".
1199 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1200 does not print anything except warnings for records.
1202 For yaz-marcdump, added support for MARC split into files (-s) with a given
1205 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1206 spec, at http://www.loc.gov/standards/sru/record-update/
1207 This has changed the binary layout of the following structs:
1208 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1209 bend_update_rr . Patch by Ko van der Sloot.
1211 Added GFS utility function bend_assoc_is_alive which returns 1 if
1212 association is still alive (client is connected); 0 otherwise (client
1213 closed connection). This allows busy servers to stop working for
1216 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1217 been a separate piece of software. This version of ziffy has been modified
1218 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1220 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1222 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1223 Client code may now interrogate options such as "init_opt_sort" to
1224 find out whether the server claims to support various options.
1226 --- 2.1.40 2006/11/27
1228 Added utilities yaz_{set,get}_esn to set/get element set name from
1231 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1232 of YAZ and has been so since YAZ 2.1.10.
1234 Implemented ZOOM_record_error which returns error information for
1235 record (surrogate diagnostic).
1237 --- 2.1.38 2006/10/31
1239 Updates for SRU Update by Ko van der Sloot:
1240 1. Changed name from "operation" to "action"
1241 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1242 versions in the code, marked as 'backward compatible'.
1243 3. Added diagnostics for SRU Update.
1245 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1247 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1249 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1251 For GFS, fixed problem with SRU diagnostic 'First record position out of
1252 range' being issued for 0 hits.
1254 zoomtst10 part of Windows Build.
1256 --- 2.1.36 2006/10/13
1258 Implemented yaz_filepath_comp which splits a path into file path
1259 components (required by Zebra 2.0.3+).
1261 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1262 BSD inspired license until now so this should not have any real impact on
1263 anybody. See http://www.opensource.org/licenses/bsd-license.php
1265 Fixed bug #687: Missing log lines.
1267 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1270 Fixed bug #689: SRU diagnostics to be added.
1272 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1273 whether a connection is idle (no more work do do).
1275 --- 2.1.34 2006/10/04
1277 Change type of optval from long to int for invocation of setsockopt with
1278 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1280 Added support for specifying the max log file size for the Generic
1281 Frontend Server. The size is given with option -r.
1283 --- 2.1.32 2006/09/21
1285 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1287 --- 2.1.30 2006/09/17
1289 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1292 Fixed bug in Generic Frontend Server that could cause a server to stop
1293 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1295 For the generic frontend server, the maximum record size is used as maximum
1296 size of incoming packages (SRU + Z39.50). The value until was previously
1297 only used in Z39.50 Init negotiation and, later, in a session controlled
1298 sizes of records returned. This is controlled using -k option. It can be
1299 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1301 --- 2.1.28 2006/09/04
1303 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1306 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1308 New option for yaz-marcdump -lpos=value which allows setting a portion
1309 of MARC header to a certain value.
1311 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1313 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1314 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1316 --- 2.1.26 2006/08/15
1318 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1321 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1323 --- 2.1.24 2006/08/08
1325 Fixed MARC ISO2709 encoding routines to deal with character set
1328 Minor changes to GFS logging. Database included in search request log
1331 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1332 cached/multiple records.
1334 Shared libraries are built by default on Unix+configure.
1336 Changed cql2pqf transformation to use a different evaluation order. The
1337 new order is: always, relation, structure, position, truncation, index
1338 and relationModifier. Old order was: always, relation, relationModifier,
1339 structure, index, position, truncation. Note that the the latter ones
1340 override former ones for identical attributes.. The new scheme means that
1341 it is possible to override any existing attribute with a relationModifier.
1342 And also that it is possible to override everything for the index rule
1343 (except the ones listed in relationModifier). No order is perfect but this
1344 one, we believe, covers more real cases.. The "always" should have been
1345 called "default", since the attributes there can be overridden with all
1348 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1349 compilation phase, but also for yaz-config --cflags output. This allows
1350 us to have public headers with Libxml2 stuff in them . It should also,
1351 eventually, make Libxml2 checks redundant in packages using YAZ, such
1354 --- 2.1.22 2006/06/15
1356 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1357 stored in uri, message and details.. Previously diagnostics were stored
1358 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1359 compatibility.. but he's probably the only one affected, so.
1361 Added support for CCL, compiled on the client side, in ZOOM-C. This
1362 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1363 input; the resulting query objects can be used for for searching with
1364 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1366 YAZ' configure searches for OpenSSL by default.
1368 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1369 SL_CTX_use_certificate_file. See
1370 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1371 for more info. Thanks to Ko van der Sloot.
1373 --- 2.1.20 2006/06/02
1375 Bug #600: SRU GET, POST support for yaz-client. Introduced
1376 command 'sru' which selects method SOAP/GET/POST.
1378 Allow missingValueAction to be specified for the sortspec string -
1379 function yaz_sort_spec. By default, the missing value action is null.
1380 Use ! to specify "abort". Use = followed by stringvalue to specify default
1383 Ensured that Present-handler (if defined) is called in GFS before any call to
1384 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1385 searchRetrieve requests.
1387 Documentation for YAZ is now based on the Docbook XML/XSLT using
1388 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1389 is no longer depending on jade/openjade or docbook-to-man scripts.
1390 PDF is no longer part of the distribution - but can optionally be
1391 made using DSSSL/jadetex or FOP.
1393 Added retrieval handling support in Generic Frontend Server to support
1394 conversion between MARC/XML as well as XSLTtransforms. See
1395 etc/yazgfs.xml for an example.
1397 Added Authentication support to Generic Frontend Server in SRU
1398 mode. Authentication using HTTP Basic is supported, as is the use
1399 of 'x-username' and 'x-password' parameters in the request itself.
1401 Added support for a new character set MARC8s identical to MARC8 except
1402 that it converts combined characters to single Unicode characters in the
1403 Latin-1 range (when possible).
1405 --- 2.1.18 2006/04/24
1407 ASN.1 compiler 0.4: generates brief Doxygen file header for
1408 generated .h/.c files.
1410 Utility yaz_iconv now supports conversion to MARC-8.
1412 New facilities for the MARC module. The reading - and writing of
1413 content are separate methods for the yaz_marc_t handle. The following
1414 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1415 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1416 format). Write functions have prefix yaz_marc_write_.. The existing
1417 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1418 available. Removed support for OAI-MARC and simplexml (not the
1419 simplexml from PHP5).
1421 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1422 to be returned for this connection.
1424 --- 2.1.16 2006/03/31
1426 Allow multiple languages and charsets to be specified with
1427 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1428 negcharset iso-8859-1,utf-8
1430 Translation of proximity nodes from CQL into PQF now works.
1432 Moved to automake 1.8, 1.9.
1434 Added function yaz_log_set_handler which allows a log handler to be
1435 installed. This handler will be called for all log messages. Output
1436 to file is also produced; but that can be disabled by passing NULL
1437 fname to yaz_log_init_file.
1439 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1441 For SRW (including GFS), accept application/soap+xml as content-type
1444 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1445 produces NO stylesheet reference even if a default stylesheet is specified
1448 --- 2.1.14 2006/03/14
1450 Updated Windows package to include yazd.dll + yazd.lib for the
1451 Development component.
1453 If the environment variable YAZ_LOG is set, then it is used as a
1454 string indicating the default level of logging to use if not
1455 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1456 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1457 used as before. So, for example, to omit warnings from YAZ logging,
1458 export YAZ_LOG=-warn
1460 cql_transform() now map structure and other attributes before indexes,
1461 so that index-specific structures and other attributes can override
1462 defaults. So now a combination of mapping specifications such as:
1464 index.dc.date = 1=date-modified 4=5
1465 does the right thing.
1467 cql_transform() now also respects the "always" mapping specification,
1468 which establishes an initial set of attributes to be used for all
1469 terms except where overridden by more specific attributes associated
1470 with the index, relation or modifier.
1472 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1473 which mode to use; one of "post", "get" or "soap" (SRW, default).
1475 Fixes for yaz_iconv routines: changed trie-based character set conversions
1476 to use only non-negative values for bit fields due to Sun's C compiler not
1477 supporting negative values.
1479 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1480 sequences where not read correctly. Fix by Rustam Usmanov.
1482 Updated win/makefile to use options, settings which makes things
1483 compile with VS C 2005.
1485 --- 2.1.12 2006/02/01
1487 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1489 In ZOOM socket code, use select instead of poll on MacOSX.
1491 ZOOM-C now support client-side compilation of CQL into RPN that is
1492 sent to the server, enabling CQL to be used against all Z39.50
1493 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1494 ZOOM_query object, and submit it using ZOOM_connection_search().
1495 The CQL-to-RPN translation uses a configuration file, the name of
1496 which must be specified in the Connection's "cqlfile" option.
1498 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1499 function, which takes as its start-term parameter a ZOOM_query object
1500 (which may have had either CQL or RPN set into it).
1503 --- 2.1.10 2005/11/29
1505 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1506 GFS to support this as well. Backend handler, bend_srw_update, does the
1507 update work. Code contributed by Ko van der Sloot.
1509 Allow retrieval of Search Result-1 information in ZOOM by the use of
1510 options that are attached to a result set. ZOOM documentation updated
1513 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1514 UTF-8 conversion. Patch by Raj Patel.
1516 Added option -m to GFS to control formatting of timestamps in log file.
1518 Added 'exit' as synonym for 'quit' in yaz-client
1520 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1521 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1522 for the new members. Patch by Ko van der Sloot.
1524 Added support for SRU POST. It is supported for content-type
1525 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1527 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1528 Instead make the library libyaz.la multi-threaded. Threading as a whole
1529 can still be disabled by configure option --disable-threads. Previosly,
1530 with older GLIBCs there were problems with MT libs under Apache. This
1531 has now been fixed a long time ago.
1533 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1536 CQL module modified to be case insensitive for relations/indexes/operations.
1538 Fixed bug in CQL transform code: incorrect value relationModifieder
1541 Added 'show all' command for yaz-client which retrieves all results
1544 Added new yaz-client, xmles, which takes a (private) OID and
1545 a document to be sent as an extended service request.
1547 Describe new yaz-client commands wait_response and set_auto_wait.
1549 Increase TCP/IP listener backlog from 3 (which I am guessing was
1550 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1551 that the socket will queue as many incoming connections as it's able
1552 to handle ongoing connections. In other words, it will never now
1553 refuse a connection that it would be able to handle merely because
1554 it's not got around to accepting() enough of the pending connections
1555 yet. This is the behaviour anyway under Linux, where the listen()
1556 argument is ignored; but not under BSD and on systems such as
1557 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1558 YAZ-based servers should now be uniform across operating systems in
1561 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1562 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1563 This allows yaz-marcdump to read large MARC batches (>2 GB).
1565 Modified all YAZ source files - except the source which is auto-generated
1566 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1569 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1570 corresponding to the existing *_setl() function. These allow option
1571 values containing arbitrary valuues.
1573 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1574 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1575 except that it returns an indicator of whether or not the sort
1576 criterion was accepted (0 for OK, -1 for invalid).
1578 --- 2.1.8 2005/06/07
1580 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1581 MARC output rather than returning "new" buffer.
1583 yaz-client warns about unknown init options.
1585 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1587 --- 2.1.6 2005/05/24
1589 Added support for SRW sort in Generic Frontend Server. Patch
1590 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1591 sortKeys - or NULL if none is provided.
1593 Fixed bug #307: It was impossible to specify indefinite/no timeout
1594 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1597 Added support for multiple languages and charsets to be specified in
1598 ZOOM. Each charset/language is separated by a blank. If negotiation is
1599 in effect in init-response, Option
1600 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1601 Code based on patch by Vasiliy Osadchuk.
1603 Fixed bug #306: infinite recursion that occurred when calling
1604 yaz_log_level_init as the first call (before other log level or
1607 Fixed bug in scan handling in front end server: if preferred-Position-In-
1608 Response was non-present, a NULL pointer referece was performed.
1610 --- 2.1.4 2005/04/26
1612 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1613 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1614 now defined for all those error codes. So instead of putting 109 in
1615 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1616 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1618 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1621 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1623 Program yaz-client now exits and produces an error message if multiple
1624 Z39.50 servers are specified on the command line (none or one allowed
1627 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1630 --- 2.1.2 2005/03/16
1632 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1634 Fixed bug #272: Preserve spacing for CCL terms.
1636 --- 2.1.0 2005/03/14
1638 Added support for virtual hosts and multiple backend servers for
1639 the YAZ frontend server. The configution is XML based and
1640 support specificition of CQL to RPN mappings and explain information.
1641 See section "Virtual Hosts" in the YAZ manual.
1643 Extended OPAC display utility. OPAC display utility renders
1644 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1645 to supplement yaz_marc_decode_wrbuf.
1647 Fixed a bug in MARC decoder that could caused it to crash for some
1648 invalid MARC records. More diagnostics and warnings where added in
1649 XML output (warnings, etc are stored in comments).
1651 --- 2.0.34 2005/02/08
1653 Fixes for UNIX domain sockets. Bug #261.
1655 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1657 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1658 Added yaz_marc_subfield_str which defines subfield lead string which is
1659 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1660 yaz_marc_endline_str which defines end of fields string used in
1661 YAZ_MARC_LINE format. Default string is newline.
1663 Experimental support for MarcXChange. This format can be produced
1664 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1665 http://www.bs.dk/standards/MarcXchange.xsd
1667 Added yaz-client commands scansize that sets maximum number of
1668 entries to be returned by scan.
1670 --- 2.0.32 2005/01/11
1672 Added support for SRW scan in yaz-client and Generic Frontend Server.
1674 * Added whereInList member to SRW Scan Term.
1676 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1678 Fixed NMEM system to return aligned blocks on the smallest boundaries
1679 that are suitably aligned for all possible types on the particular
1680 architecture YAZ is being built for.
1682 --- 2.0.30 2005/01/04
1684 Fixed numerious warnings that was issued with newer versions of GCC.
1686 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1687 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1690 Make YAZ Generic Frontend Server slightly faster.
1692 Enhance (and reduce) logging for Generic Frontend Server.
1694 Revert YAZ log system so that it flushes every write operation
1695 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1697 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1698 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1699 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1700 will effectively disable old definitions.
1702 --- 2.0.28 2004/11/09
1704 Added yaz_log_time_format which specifies log format using
1707 Added yaz_log_module_level which returns mask for a module. Value
1708 is non-zero mask a if module is enabled; zero if disabled.
1710 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1711 in include/yaz/cql.h.
1713 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1715 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1717 Fixed bug #172: RPM builds does not enable SSL.
1719 Doxyfile.in part of dist. Doxyfile generated by configure.
1721 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1722 are given and the corresponding component does not exist.
1724 Extend CCL documentation in YAZ reference. Describe r=r.
1726 --- 2.0.26 2004/10/01
1728 Fixed MARC->MARCXML conversion to properly deal with
1729 fields, subfields, indicators having non-ASCII characters.
1731 Fixed MARC->MARCXML conversion so that ASCII control characters
1732 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1735 Added YAZ GFS support for conversion from Z39.50 surrogate
1736 diagnostics to SRW surrogate diagnostics.
1738 Bug fix: YAZ GFS did not return schema in explainResponse.
1740 --- 2.0.25 2004/09/30
1742 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1743 now converts recordSchema to elementSetName as well as schema URI.
1745 Fixed bug in COMSTACK that prevented HTTP request packages from being
1748 --- 2.0.24 2004/09/29
1750 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1751 does not require white-space before and after the dash in a range, e.g.
1752 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1755 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1756 due to new GCC removing "redundant" code.
1758 Added yaz-client commands scanpos and scanstep that sets preferred
1759 position and step-size for scan.
1761 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1763 Added CCL utility ccl_qual_buf which parses one or more CCL
1764 spec lines in a buffer.
1766 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1767 of name and value - ignoring empty lines and comments.
1769 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1771 Added odr_get_element_path which returns current element path for an
1772 ODR handle. This utility is useful in error handling or user-defined
1775 Added ODR_PRINT utility odr_set_stream which is is a more generic
1776 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1777 to a write function and pointer to close function. The close function - if
1778 non-NULL - will be called during odr_destroy.
1780 Fixed bug in CCL parser where truncation char was not removed from
1781 right side when truncation=both was in effect.
1783 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1786 --- 2.0.23 2004/08/11
1788 Fix buffer overrun in CQL parser when dealing with proximity (%).
1790 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1791 to UTF-8/UCS conversion is now only based on codetables.xml.
1793 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1795 --- 2.0.22 2004/08/06
1797 Add support for more "commit changes" in ZOOM (uses Extended Services).
1799 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1802 Yet another small fix for configure of SSL.
1804 --- 2.0.21 2004/05/14
1806 Fix SSL libs for configure when --with-openssl=DIR is given.
1808 --- 2.0.20 2004/05/10
1810 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1812 SSL comstack now uses yaz.pem certificate file on server side
1813 by default. Certificate filename can be configured by calling
1814 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1816 Fix bug regarding multiple calls to ZOOM_connection_connect.
1818 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1820 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1821 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1823 ZOOM now allows inspection of X509 peer certificate for verification.
1824 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1826 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1827 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1828 as "modular" but it simplifies things.
1830 Added cs_get_peer_certificate to that returns peer X509 PEM.
1832 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1833 NULL if SSL is unavailable.
1835 Documentation about MARC decoding tools.
1837 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1839 --- 2.0.19 2004/03/30
1841 Rename CHANGELOG to NEWS to follow GNU style packing.
1843 Fix bug with missing initialization of member in init_diagnostics.
1844 This bug affects threaded version of GFS server.
1846 --- 2.0.18 2004/03/20
1848 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1851 Ensure zlib.dll is packed with Windows install.
1853 --- 2.0.17 2004/03/17
1855 Fix encoding of xsd:string to use text instead of CDATA.
1857 Fix endless loop in CQL parser with unbalanced ".
1859 Use a more compact way to store MARC-8 conversion tables.
1861 --- 2.0.16 2004/03/16 Debian only
1863 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1866 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1871 --- 2.0.15 2004/03/01
1873 Another fix for decoding of XML packed records.
1875 --- 2.0.14 2004/02/25
1877 Fixes for Chunked encoding. White space not ignored after length spec.
1879 Update NS and use default NS for SRW diagnostic elements.
1881 --- 2.0.13 2004/02/23
1883 Implement ZOOM_resultset_cache_reset which resets record cache.
1885 Implement ZOOM_resultset_sort which sorts a result set.
1887 Implement chunked HTTP transfer.
1889 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1891 --- 2.0.12 2004/02/16
1893 Added member 'schema' to bend_explain_rr structure so that backend
1894 can specify explain record identifier. Defaults to Zeerex 2.0.
1896 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1898 --- 2.0.11 2004/02/16
1900 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1903 Added init command for yaz-client which sends "extra" init request.
1905 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1906 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1908 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1910 Make ZOOM error code for "invalid query".
1912 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1914 --- 2.0.10 2004/02/05
1916 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1919 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1921 Added option -p <file> to make Generic Frontend Server to write PID file.
1923 Added option -D to put Generic Frontend Server in background on its own.
1925 Make ZOOM C recognize option "password". If unset, "pass" is used
1926 (for backwards compatibility).
1928 Fixed a bug in Generic Frontend Server that could make it crash if a
1929 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1932 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1933 Must be issued before open, in order to be in effect.
1935 --- 2.0.9-6 2004/01/12 Debian/Windows
1937 Make the SRU server more picky WRT unknown params, etc.
1939 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1941 New YAZ client command, options, that sets Z39.50 options.
1943 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1944 options from a string of tokens (one token for each option bit).
1946 Update SRW diagnostic code messages.
1948 --- 2.0.9-5 2004/01/07 Debian/Windows
1950 Handle user defined stylesheet for SRW/SRU.
1952 --- 2.0.9-4 2004/01/06 Debian/Windows
1954 Fix bug in decoding of Content-Length.
1956 --- 2.0.9-3 2004/01/06 Debian/Windows
1958 Fix a bug with decoding of XML packed records.
1960 --- 2.0.9-2 2004/01/05 Debian only
1962 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1964 Fix bug in SRW/SRU diagnostics decoding.
1966 --- 2.0.9 2004/01/05
1968 Fixed bug in Generic Frontend Server which could drop records exceeding
1969 preferred message size. Reported and fixed by Irina Dijour.
1971 Fixed calculation of package size for structured records in Generic
1972 Frontend Server. Reported and fixed by Irina Dijour.
1974 Fixed namespace for SRW/SRU diagnostics.
1976 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1978 --- 2.0.8 2003/12/22
1980 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1981 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1984 CQL changes to reflect recent changes to the specification:
1985 * Documentation talks about context sets instead of index sets.
1986 * Documentation talks about indexes instead of qualifiers.
1987 * The CQL-to-PQF transformer's configuration file now uses
1988 "index.set.name = <attributes>" instead of the old form
1989 "qualifier.set.name = <attributes>". (Both forms are still
1990 understood but the latter is deprecated.)
1991 * CQL terms with no explicit index specified are now interpreted as
1992 cql.serverChoice instead of srw.serverChoice (which of course
1993 behaves exactly the same.)
1995 --- 2.0.7 2003/12/16
1997 MARC conversion can now generate ISO2709 output in another
1998 character set. yaz-marcdump uses this facility if you invoke it
2001 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2002 functions from there can be used from C++.
2004 --- 2.0.6 2003/12/04
2006 Frontend server now transfers memory from decoded packages to stream
2009 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2010 references to show up.
2012 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2013 the ZOOM Abstract API. The older names for the same options are still
2014 also supported for the benefit of old applications.
2016 ZOOM-C supports "implementationId" and "implementationVersion" options
2017 to go along with "implementationName". These allow the user code to
2018 specify identification strings to be sent to servers.
2019 Add OID for the new ExtLite attribute set.
2021 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2022 as requested/supplid by Ere Maijala <ere@atp.fi>
2024 For generic frontend server, reverse the order of
2025 "toolkit-supplied / application-supplied" strings sent as implementationId,
2026 Name and Version. Also, remove the spaces around the slash. This brings
2027 the GFS in line with the behaviour of ZOOM-C on the client side.
2029 Add function ZOOM_scanset_display_term.
2031 yaz-client shows scan displayTerm if present.
2033 Utility yaz-iconv is now installed by default along with the man page
2036 Extend configure check for OpenSSL to use pkg-config where available (such
2039 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2040 server to specify uid/gid/mask for socket using the format
2041 unix:[user=uid,][group=gid,][umask=mask,]file=path
2042 If file= is omitted the existing format is assumed, e.g.
2044 in which case the mask is 0666 (rw for everybody).
2046 Major restructure of YAZ source. All source in libyaz is in src directory.
2047 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2048 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2050 Added man page for utility yaz-marcdump (used to be called marcdump).
2051 yaz-marcdump is installed by 'make install'.
2053 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2054 of incoming package failed.
2056 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2058 Change prototype of odr_perror: add const to message string.
2060 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2062 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2063 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2064 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2065 DNS lookup. There should not be any compatibility problems with this
2066 assuming that blocking=1 or 0 is used.
2068 Fix bad reference in UNIX comstack in function cs_addrstr.
2070 Fix for compilation on AIX.
2072 The generic front-end server (server/seshigh.c) now supports returning
2073 Init diagnostics to the client in User-information-field, in
2074 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2077 --- 2.0.4 2003/09/04
2079 Allow any CQL relation (not just all,any,exact,scr).
2081 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2082 that features the same UI.
2084 Implemented command update0 in YAZ client which is equivalent to
2085 update but uses old of Ext Update ASN.1.
2087 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2088 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2089 Previously no OID was used for this info.
2091 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2092 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2093 returns 'malformed search term' otherwise.
2095 SortResponse member resultCount now set to NULL in sort handler of
2098 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2101 Add three new utility functions for translating OIDs between various
2102 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2103 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2104 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2105 char *oid_to_dotstring(const int *oid, char *oidbuf);
2106 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2108 Reverted modifications for ES Update definition for z_IU0Update
2109 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2110 is back to YAZ 2.0.2.
2112 String value attributes for CCL parser.
2114 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2115 which their FirstSearch server returns in Init responses, sometimes
2116 carrying useful diagnostic information when Init fails. This has the
2117 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2118 "z39.50/oclcui.asn", where its definition is somewhat different from
2119 what OCLC document on their web-site, as required to interoperate with
2122 Support for anonymous authentication in yaz-client. Use the command
2125 * Fix the OID of the Index Data-local "admin" Extended Service from
2126 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2127 the 1000, which indicates a locally-defined OID, was a mistake.
2129 --- 2.0.3 2003/06/20
2131 Fix CCL directive @case handling so that it affects string match for
2132 both CCL keywords and qualifiers.
2134 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2135 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2136 Decoder has been updated with ASN.1 changes as listed in
2137 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2138 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2139 z_IUUpdate, remains unchanged.
2141 ZOOM_record_get may now return a record in a specific character set.
2142 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2143 "from" is the character set of record as returned by target. "to" is
2144 the character set to be returned. If omitted, "to" is UTF-8.
2146 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2148 New ODR utility, odr_getelement, which returns name of element for
2149 which encoding/decoding failed.
2151 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2152 in cases where a required element was omitted.
2154 Bug fix: some MARC8 sequences were not converted.
2156 New ZOOM option "step" which specifies number of records to be
2157 retrieved in one chunk. Used in conjunction with "start" and "count".
2159 SRW support for yaz-client. Use scheme http: to use it, e.g.
2162 yaz-client no longer does (un)intelligent character set conversions
2163 by default. Can be enabled with charset and marc_charset commands.
2165 xmalloc trace fix for 64-bit systems such as DEC alpha.
2167 Solaris 2.6 compile fix.
2169 New function, cql_strerror() translates SRW error codes, as returned
2170 by cql_transform_error(), into human-readable English strings. Used
2171 in yaz-client diagnostics when appropriate.
2173 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2174 converts it into a type-1 query which is sent to the server. This
2175 makes CQL available for use with all Z-servers, as opposed to the tiny
2176 minority that can handle CQL queries themselves.
2178 --- 2.0.2 2003/04/28
2180 New Debian package layout similar to the Redhat Package layout.
2182 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2183 and search result respectively.
2185 --- 2.0.1 2003/04/25
2187 Redhat package is now several packages: libyaz (runtime libraries),
2188 libyaz-devel (development and documentation, and yaz (utility programs).
2189 Package spec file by Morten Bogeskov.
2191 New member 'schema' in struct bend_fetch_rr which the name of requested
2192 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2193 handler MAY set this to reflect the schema of the returned record.
2195 New member 'display_term' in struct scan_entry. GFS now sets member entries
2196 and allocates scan entries to be filled by user scan handler. In previous
2197 version, entries member was allocated by the scan handler. That still works,
2198 but the GFS will ignore member display_term - assuming it was NOT set by
2199 the handler. The fact that the GFS now allocates the entries both allows
2200 for new members and makes a scan handler easier to write.
2202 Fix CQL lex buffer overflow.
2204 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2205 SRU default recordPacking is string.
2207 SRU protocol support for frontend server.
2209 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2211 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2213 Added scan for the ZOOM shell (zoomsh).
2217 * String Identifers for Schemas (Amendment 5).
2218 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2219 Old definition for schema
2220 Odr_oid *schema; /* OPT */
2225 Z_InternationalString *uri;
2226 #define Z_Schema_oid 1
2227 #define Z_Schema_uri 2
2230 * resultCount parameter to Sort Response (Amendment 1).
2231 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2233 Support for SRW 1.0 over HTTP. This is an optional feature and
2234 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2237 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2238 on the same port. SRW SearchRetrieveRequests are mapped
2239 to bend_init,bend_search,bend_fetch,bend_close.
2241 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2243 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2244 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2246 ZOOM connections are SRW based if schem http is used for hostname
2247 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2248 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2250 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2251 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2252 distance=n, order=true/false, relation=le, prox unit=word. If
2253 n is omitted, distance 1 is used.
2255 Fixed problem with C compiler include path in wrong order.
2257 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2258 on Solaris. Patch from Ko van der Sloot.
2260 New MARC decode API. All new functions operate on a yaz_marc_t
2261 handle. The most important new functions are: yaz_marc_create,
2262 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2263 decode and destroy respectively. Decoder can produce formats
2264 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2265 include/yaz/marcdisp.h.
2267 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2268 to UTF-8, UCS-32, wchar_t or Latin-1.
2270 * Prototypes for yaz_iconv_-functions moved to separate header
2271 include/yaz/yaz-iconv.h.
2273 Make a few private functions 'static' in unix.c. This prevents
2274 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2276 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2277 are set when Init Response is received.
2279 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2280 but returns diagnostic set as well.
2282 New function yaz_strerror which is a portable wrapper for
2283 strerror/strerror_r/GetLastMessage.
2285 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2286 is returned for MARC. If type is "oai", then OAI MARC is returned.
2288 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2291 --- 1.9.2 2002/11/26
2293 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2295 Fix bad race conditions on SIGTERM and terminate gracefully in
2298 Move retrieval (data1) module to Zebra since nobody seems to be
2301 Add GRS-1 render for ZOOM using same format as yaz-client.
2303 --- 1.9.1 2002/10/05
2305 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2307 Fix broken ESpec handling in data1 module.
2309 SGML reader parses comments and makes them part of the data1 tree.
2311 Added several type casts so that YAZ compiles as C++ code.
2313 ZOOM didn't handle PDU encoding failures properly.
2315 Added more Bib-1 diagnostics (approved extensions).
2317 GNU configure: better check for iconv.
2319 More portable use of accept, getpeername. Check for socklen_t. Use
2320 int/size_t if socklen_t is not defined.
2324 PQF parser rejects bad queries - including those with extra
2325 characters in them. PQF parser used to silently ignore that.
2326 Cleaner API for PQF added, which allows you to get detailed
2327 error information for bad queries (see yaz/pquery.h).
2329 Fixed bug in ZOOM_record_get for type "database".
2331 Implemented mini iconv library supporting conversions between
2332 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2334 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2336 --- 1.8.9 2002/08/20
2338 Fixed ZOOM C record cache so that preferredRecordSyntax and
2339 elementSetName is used to check for already fetched records.
2341 --- 1.8.8 2002/08/02
2343 Added three members in bend_initrequest structure to facilitate
2344 character set negotiation.
2346 Fixed a bug in frontend server that could cause indefinite
2347 loops under rare conditions.
2349 Revised character set utilities (charneg.h) so that encoding
2350 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2352 For PQF, directive @term <type> sets term type for Scan/Search.
2353 Here <type> is general, string, numeric, null. The term type
2354 is inherited - just like @attr.
2356 New call odr_set_charset that sets character set conversion for
2357 international-strings on a ODR stream. Prototype is:
2358 int odr_set_charset(ODR o, const char *to, const char *from);
2359 The InternationalString is still represented as C string in YAZ
2360 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2361 won't). On the protocol level, you can use any encoding.
2363 Support for UNIX sockets in ZOOM.
2365 Solaris recv sometimes returns errno == ENOENT. It is treated as
2366 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2368 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2369 both client and server. Code by Morten Bogeskov.
2371 --- 1.8.7 2002/05/22
2373 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2374 that they can be used directly from Visual Basic. You must recompile
2375 your windows APP if you're using ZOOM.
2377 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2378 Commands "lang" and "charset" sets language and character set respectively.
2379 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2380 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2382 Attributes from multiple CCL fields may be OR'ed rather than merged
2383 using directive "@field or". Fields are still merged by default -
2384 equivalent to "@field merge".
2386 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2389 Fixed bug in zget for parameter ExtendedServicesResponse.
2393 --- 1.8.6 2002/03/25
2395 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2397 Client displays USR.1:SearchResult-1 (hits per term).
2399 Additional Search Info for search in Generic Frontend Server.
2401 Fixed CCL parsing of "field=s".
2403 WIN32 installer - using the excellent NSIS software from nullsoft.
2405 Fixed CCL parsing of "field = - <number>".
2407 Added function yaz_marc_decode that decodes MARC for line mode
2408 display or XML (similar to that used by JZKit).
2410 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2411 Z39.50. But ISO/ILL was, however.
2413 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2414 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2416 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2417 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2419 --- 1.8.5 2002/02/03
2421 New YAZ client features: Command completion and new commands:
2422 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2423 Code provided by Jacob Poulsen.
2425 New call oid_trav, that visits all registered OIDs via callback.
2427 Function ZOOM_record_get now returns const char pointer rather than
2428 void pointer. It saves a lot of type casts.
2430 For YAZ client, command "auth" now allows you to set authentication
2431 in IdPass style. It is enabled when three tokens are given - order
2432 is user, group and password.
2434 Fix memory leaks in MARC record handling for ZOOM.
2436 New option for YAZ client, -k <kilobytes> that sets
2437 maximum record size. Similar to -k option for generic frontend
2438 server and yaz-ztest.
2440 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2442 Prefix query parser reports "fail" when bad attribute set is given.
2444 Fix in MARC decoder. Proximity logging. Fix for attribute set
2445 in scan handler for server. Patches by Shigeru Ishida.
2447 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2450 Configure option --with-openssl=<dir> now works when a directory is
2451 specified. Patch provided by Morten Bogeskov.
2453 New option for YAZ client, -u <auth>, that sets authentication.
2455 ZOOM fix: error information was sometimes "missing", since error
2456 was cleared/reset too when it shouldn't.
2458 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2460 --- 1.8.4 2002/01/04
2462 Scan for ZOOM API. New object ZOOM_scanset. New functions
2463 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2464 ZOOM_scanset_destroy.
2466 New ZOOM function, ZOOM_connection_last_event, that returns type
2467 of last event (such as "receive data", "send data", "apdu received",
2470 New ZOOM option, schema, that specifies schema for retrieval.
2472 New CCL feature. Qualifiers can be aliases for one or more
2473 other qualifiers (if more than one is given, OR is used).
2475 ZOOM uses named result sets if target supports it.
2477 Two new YAZ client commands: . (dot, which sources a script of YAZ
2478 client commands), and ! (to execute shell command.). Implemented
2481 Working on Debian packages.
2483 --- 1.8.3 2001/11/19
2485 YAZ client enables named result sets only if target supports it.
2487 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2489 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2490 with key="host" to get same result.
2492 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2493 Function Z3950_resultset_record(s) returns references to records
2494 "owned" by resultset. To become owner use Z3950_record_clone.
2496 Function z_ext_record handles Extended Services. Thanks to
2499 --- 1.8.2 2001/11/12
2501 CCL Parser fix: ignore token comma when dealing with and-lists.
2503 Documentation updates for COMSTACK.
2505 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2506 Changed prototype Z3950_records. For some functions, int parameters
2507 were changed to size_t.
2509 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2512 New MARC decode/display function, marc_display_exl, which properly rejects
2513 non-ISO2709 records. YAZ client uses it.
2515 --- 1.8.1 2001/10/29
2517 Fix bug: local attribute set wasn't set correctly in PQF strings.
2521 * Old Z39.50 codecs no longer supported.
2523 Added ZOOM C binding. See http://zoom.z3950.org/
2525 Renamed states for COMSTACKs to avoid confusion with events.
2527 Implemented cs_look and proper cs_rcvconnect.
2529 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2531 Configure detects POSIX threads on OpenBSD.
2533 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2534 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2536 When error is returned from present handler, non-surrogate diagnostic
2537 is returned in present response (and fetch handler is no longer called).
2539 * Minor adjustments to pquery parser (PQF). Token characters may be
2540 escaped by using backslash (C-style).
2542 PQF parser allows string attribute values to be specified. For @attr,
2543 non-numeric characters after the equal-sign are treated as strings
2544 (e.g. @attr 9=title).
2546 CCL trunction character may be defined (@truncation in file)
2548 * function zget_ExtendedServicesRequest sets waitAction to
2549 waitIfPossible (was wait).
2551 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2554 CCL operator names may be set in field definition files (CCL_bibset).
2555 See ccl/bib1 for an example.
2557 Fixes in ASN.1 compiler for C++ compatibility.
2559 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2560 and "op_or" to avoid conflict with C++.
2562 Fixed problem with GNU readline detection on Redhat 7.0.
2564 Added step-size for Scan backend handler.
2566 Fixed bug that made the frontend server crash when no attribute
2567 set was specified for scan.
2569 Front-end server automatically switches to original working directory
2570 when installed as an NT service. Previously -w had to be specified to
2573 Added extended attributes for retrieval module (data1), so that data1
2574 records carry d1_readXML/SGML attributes. d1_read also supports
2575 null-data rules ( <tag/>)
2577 On UNIX when POSIX threads are available, a separate library libyazthread
2578 is created. Programmers should link with that library and the yaz library
2579 when using threads. The reason for the split was that some applications
2580 on Linux, such as Apache, doesn't work well when using shared objects that
2583 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2584 (or any frontend server) in SSL mode by specifying ssl: followed by
2585 address. Only tested on UNIX.
2587 Added feature for CCL module. Virtual structure s=al or s=ol generates
2588 and-list and or-list respectively instead of phrase search.
2592 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2593 log_mask_str. This was done to avoid name conflicts with other libraries
2594 (such as other PHP extensions).
2596 Added raw OID member for preferred record syntax (request_format_raw)
2597 and returned record syntax (output_format_raw) for backend fetch method.
2599 Config file yaz-config now accepts options so that it returns specific
2600 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2602 Shared library support for UNIX using GNU libtool.
2604 * Modified backend interface. Request/Response struct's replaced by
2605 one read/write C struct. For example bend_fetchrequest and
2606 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2607 Every handler - even search has to be registered in bend_init
2608 handler. This means that the YAZ library no longer refers to
2609 external functions and it makes it possible to make the whole
2610 thing a single DLL/SO.
2612 Added Segment handler for backend server.
2614 Added Zmbol/Zebra administrative functions to YAZ client.
2616 Threaded frontend server on UNIX (when POSIX Threads are available).
2617 Starting the server with option -T enables multi-threading.
2621 Added configure option --enable-comp/disable-comp to control use
2622 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2623 located in sub directory asn.
2625 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2626 in ${exec_prefix}/bin along with the other programs yaz-client and
2629 GNU automake used to maintain makefiles.
2631 Added several OID's.
2633 Changed retrieval module so that we can load records with no abstract
2634 syntax defined. Tagpaths in these records are fully composed of string
2637 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2641 On UNIX, the generated makefile now supports a proper 'make install'.
2642 The prefix can be set via GNU configure to set the install location
2643 (default is /usr/local).
2645 * YAZ programs client and ztest were renamed to yaz-client and
2646 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2647 locations, such as /usr/bin,/usr/local/bin,etc.
2649 * YAZ Header files were moved from include to include/yaz. YAZ Header
2650 files are referred to as include <yaz/log.h> rather than <log.h>.
2651 The YAZ include path (-I ..) is therefore the same as before. Programmers
2652 should update their #include statements or use -Ipath/include/yaz
2653 instead. The main motivation for doing this change is that YAZ header files
2654 can be installed in "standard" locations /usr/include,/usr/local/include
2655 without introducing conflicts, since ALL YAZ header files are stored
2656 in subdirectory yaz (under /usr/include for example).
2658 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2659 rather than project/workspace files. We switched because project files
2660 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2663 Changed name of logging function, logf, to yaz_log, to prevent name
2664 clash with some math-log functions. The YAZ header log.h defines logf
2665 to yaz_log (#define) so there should be no incompatibilities by this
2668 Added bend_start/bend_stop handlers for server. These handler are
2669 called on start/stop of server. For windows they are called whenever
2670 a service is started/stopped.
2672 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2673 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2674 in util/yc.tcl. The auto-generated C code structures are, in a few
2675 cases, incompatible with the old decoders. There are differences in the
2676 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2677 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2678 The preprocessor variable ASN_COMPILED is defined when the compiled
2679 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2680 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2681 wish to use the old encoders/decoders you can specify --disable-yc
2684 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2685 version so that it supports both new - and old version of DB Update
2687 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2688 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2689 change. The name parameter can be set to 0 in which no name is specified
2690 for the construction. The macros odr_implicit and odr_explicit sets name
2691 parameter to zero for the construction involved. New macros
2692 odr_implicit_tag and odr_explicit_tag are similar to the others,
2693 except that a name parameter is added. For programmers' that don't use
2694 ODR they probably only need to change the call to z_APDU and z_External.
2696 Added access control facility by interfacing the TCP wrapper library.
2697 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2698 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2699 name of the daemon and enables the access control as specified in
2700 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2702 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2703 den Dool <H.M.vdnDool@kub.nl>.
2705 Added reference ID parameter to most functions in server API - refer
2706 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2708 Changed name of ccl library to libccl.a (was ccl.a).
2710 Fixed bug in decoder for Explain (Category TargetInfo).
2712 Added support for GNU readline in client. Thanks to Jacob Poulsen
2713 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2715 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2716 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2717 IMPLEMENTATION! This change was made to the development version before
2718 the ZIG decided to retract the amendment. If any users MUST be
2719 compatible with the original Update definition, PLEASE CONTACT US, and
2720 we will include a separate definition corresponding to the old Update
2721 ES. Note that because of the change to the ASN.1 of the
2722 TaskPackageRecordStructure we cannot define a single structure that
2723 will support both versions.
2725 * Added const modifier to buffer parameter for some ODR/BER encoding
2726 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2727 completeWAIS, odr_dumpBER.
2729 Fixed bug in client.c which caused a crash when a scanResponse didn't
2730 contain positionOfTerm.
2732 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2733 * will cause an error in a client if a non-YAZ target sends both a
2734 * list of Scan entries and non-surrogate diagnostics.
2736 Retrieval module enhancements. Tag sets may be typed in the reference
2737 to it. From the .abs-file the "tagset" directive takes a third optional
2738 integer type for the tag set referenced. From a .tag-file the "include"
2739 directive takes a third optional type as well. The old "type" directive
2740 in the tag set itself is still recognized but acts as the default type
2743 Backend interface change. Individual Scan terms returned from bend_scan
2744 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2745 in include/backend.h.
2747 Retrieval module enhancements. Multiple tag sets and attribute sets may
2748 be specified in abstract syntax specs. Revised the error/warning for
2749 logging messages reported by the retrieval module when reading the
2752 Object Identifier system (oid_..) changed. The API is backwards
2753 compatible but the oid-routines now allocates new OID's when needed.
2754 Raw OID's may be specified in oid_getvalbyname.
2756 YAZ now uses GNU configure to generate Makefile(s).
2758 * Minor changes in some of the member names of DeleteResultSetRequest and
2759 DeleteResultSetResponse. See include/proto.h.
2761 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2762 and added member 'languages' in TargetInfo (which was missing).
2764 Changed the way attribute sets are handled in the retrieval
2765 module. These are now cached, just like the abstract syntaxes
2768 Changed YAZ so that it links with compiled ASN.1.
2770 Added Explain-schema definitions and mapping routines. The following
2771 Explain categories have been implemented: AttributeDetails,
2772 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2774 Fixed minor bug in Windows version of Server Library.
2776 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2778 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2780 Added EXTERNAL: UNIverse Resource Report (non-standard).
2782 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2783 ENUMERATED and SET OF.
2785 * Added 'const' to some of the char pointer arguments for the
2786 functions, data1_read_node, data1_getelementbytagname,
2787 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2790 Fixed bug in data1_insert_taggeddata - the last_child member of
2791 parent wasn't initialised.
2793 * Changed data1_read_record and data1_read_node so that the supplied
2794 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2795 doesn't refer to any parts of the "SGML"-buffer.
2797 Fixed bug in server library (Windows version of statserv_remove).
2799 * Changed code so that it compiles as C++. The type definition
2800 of Odr_fun which is a member of Odr_arm was changed. The result is,
2801 that an explicit typecast is needed for the fun pointer when
2802 using Odr_arm - as in:
2803 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2805 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2807 Implemented the new structured date and time definition as approved
2808 by the ZIG. Added schemaId element to the specificTag in Espec-1
2809 (also approved at the last ZIG). Thanks to RVDM.
2811 Added some Object identifiers (RVDM).
2813 Changed the Update Extended Service (RVDM).
2815 Added command "refid" to client which specifies referenceId for
2816 the following requests.
2818 Implemented extended service handling for server. See ztest.c
2819 for an example as well as backend.h. New handlers are registerd
2820 in the Init handler.
2822 * Changed interface for sort in server.
2824 Added new members to statserv_options_block. It allows a server
2825 to read options from another source than just the command line. Thanks
2826 to Charles Woodfield.
2828 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2829 renamed to zboolean. Some C++ compilers complained about the name.
2831 Minor changes to gils.abs. Added index 's' (sort) on title
2832 and date/time-last-modified.
2834 --- 1.4pl2 1998/1/30
2836 Fixed bug in server library regarding inetd mode (-i). This bug
2837 was introduced by release 1.4.
2839 --- 1.4pl1 1998/1/29
2841 Added sort facility in client and backend server interface.
2843 Fixed problem with dependencies in Makefile(s).
2845 Fixed bugs for encoders/decoders of extended services and
2848 Implemented sub-tree feature for schemas. Sub-trees are
2849 referenced in *.abs-files. See explain.abs for an example
2850 of the use of this feature.
2852 Modified bib1.att; local attributes for ANY didn't include
2853 ANY itself (only affects use of the retrieval module).
2855 Fixed bug in plain SGML reader in function data1_read_node:
2856 tags with prefix "var" was incorrectly interpreted as variants.
2858 Added feature "sub-schemas" to enable references to - and definitions
2859 of - group of elements.
2861 * Removed member parent from type data1_element (in data1.h).
2863 Implemented function odr_nullval() that returns the value of
2866 * Removed member num_children from data1_node (in data1.h).
2868 Made NT service interface part of the server library. The
2869 function statserv_main uses the NT service when required and
2870 calls the statserv_start / statserv_close routines.
2872 Routine zget_SearchRequest and zget_PresentRequest fills
2873 resultSetName/Id member with "default" instead of "Default".
2875 Fixed memory leak in server. Request queue member wasn't freed.
2877 Fixed nmem_exit so that memory is freed.
2881 Revised the CCL parser utility to be thread safe.
2883 Added function, oid_ent_to_oid, to replace the function
2884 oid_getoidbyent, which is not thread safe.
2886 * Added nmem_init and nmem_exit to initialize and release
2887 NMEM resources. Function nmem_init should be called once in the
2888 initial thread before NMEM/ODR is used. statserv.c and client.c
2889 have been changed accordingly. The change was necessary to make
2890 NMEM thread safe. The NMEM memory pool is shared amongst threads
2891 in a process. Unix-based applications will still work fine without
2894 Added NT Services interface for the the Z39.50 (statserv) Server.
2895 Refer to the ztest.c source on the usage.
2897 Windows 95/NT port using MSVC5.0. Project files are included in the
2900 * Defined new 'global' handle for the retrieval (data1) system. The
2901 new handled, data1_handle, describes the state of the data1 system.
2902 This handle is passed as first argument to virtually all
2903 data1 related routines. The functions data1_create and data1_destroy
2904 creates and destroys a data1 handle respectively.
2906 Added ODR encode stream member to all backend request structures
2907 init, search, scan etc. This stream should be used to allocate all
2908 memory used for the response when thread safe operation is needed.
2910 Changed the comstack utility, cs_addstr, to be thread safe. The
2911 returned hostname string returned by the function is now part the
2914 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2915 function. The cs_straddr takes a COMSTACK handle as argument, so this
2916 function must be used after cs_create and before bind/connect.
2917 This function is thread safe.
2919 Moved test server to 'ztest' directory - generic server code still
2920 in 'server' directory.
2922 Made prefix query (pquery.c) utility thread safe.
2924 Added new function modifier YAZ_EXPORT to 'export' public DLL
2925 functions when using windows (see include/yconfig.h).
2927 Added definitions to the OID database (util/oid.c) (RVDM).
2929 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2931 Added call to ccl_rpn_delete in client program.
2933 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2934 release of RPN structure.
2936 Added support for C++, headers uses extern "C" for public definitions.
2937 With input from RVDM.
2939 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2940 Thanks to Ronald van der Meer (RVDM).
2942 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2944 Added support for private extensions to the OID database
2945 (oid_setprivateoids()). Thanks to RVDM.
2947 Added optional, physical ANY (key replication)
2949 Fixed null-reference problem in GRS-1 output filter.
2951 Proximity operator added to Prefix Query Format (PQF).
2953 In test client command "base" accepts multiple databases.
2955 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2959 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2961 Smallish bug-fixes in the new encoders/decoders (explain).
2963 Bug fixed in DeleteRequest.
2965 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2967 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2969 Added SOIF syntax (using private OID for now) to retrieval module and client.
2971 Added Update extended service.
2973 Added SearchResult-1 additional info structure.
2975 Added optional CCL (ISO8777) interpreter as separate module. Available
2978 --- 1.2 1996/6/10 (1st anniversary release)
2980 Added Summary record syntax. Lightly tested.
2982 Added OPAC record syntax. Untested.
2984 Added ResourceReport service encoders/decoders. Untested.
2986 Fixed bug in z_Unit - wrong tagging on unitSystem.
2988 Fixed bug in the DiagRecs decoder.
2990 Added options for max PDU size and session timeout to frontend-server.
2992 Added documentation of query-language parsers and other supporting utilities.
2994 [frontend-server] Added Attribute set to the bend_scanrequest API.
2996 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2997 surrogate diagnostics were generated.
2999 [retrieval] Allow multiple local values for attribute.
3001 [retrieval] Allow multiple attributes per element in .abs files. index type.
3003 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3005 --- 1.1pl2 1996/4/10
3007 Minor changes, mostly specific to Zebra's requirements (retrieval)
3011 Repaired bug in frontend server when running multiple listening
3012 endpoints in dynamic mode.
3014 z_External() now won't break if a known, ASN.1 value comes encapsulated
3015 in an octet-string. The value will pass through unmodified in an Odr_oct.
3017 Added a bit of code to the demo client to decode & display
3018 ASN.1-structured records represented in the octet-aligned branch of
3019 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3021 Added z_ext_getentbyref() to the ASN module. Doc updated.
3023 * Completed the SCAN definition in the ASN module. This may break SCAN
3024 code based on older YAZ-versions at compile-time. The fix is easy -
3027 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3028 under the SCAN definition. Remember to initialize this, server-people.
3030 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3031 that this does not extend to ODR and ASN.
3033 Comstack allows insertion of established socket (primarily for
3034 inetd-operation of servers). Doc updated.
3036 Front-end server can now start from the inetd in TCP mode. Doc
3039 --- 1.0pl4 1996/1/24
3043 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3044 the rank and record number.
3046 Adjustments to the frontend server.
3048 Fixed diagnostic BER dumper. It ignored the file argument.
3052 Various changes to retrieval module.
3054 Changed the union discriminators of the protocol files from enums to
3055 ints paired with #defines.
3057 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3060 *Changed operator in the RPN structure to 'roperator', again to avoid a
3063 Fixed problems in Explain decoders/encoders.
3065 --- 1.0pl2 1995/12/6
3067 Memory bug in log module fixed.
3069 --- 1.0pl1 1995/12/5
3071 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3073 Bug in Explain DatabaseInfo module fixed.
3075 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3079 The shift to v1.0 signals that we now consider the *core* functionality
3080 of YAZ reasonably stable (the core being more or less equivalent to
3081 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3082 tested (Explain not at all - though that will happen soonish).
3084 Minor changes to code to support Windows port.
3086 Various minor changes after we're getting to use GRS-1 & co. more.
3088 Added Espec-1 format.
3090 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3091 of the protocol and it cannot be selected when encoding (maps into 'string'
3092 when decoding). Needed to talk to some servers.
3094 Demo client can request simple element set names.
3096 Added Diagnostic Format encoders/decoders.
3098 Added simple Close handling to frontend server (no hooks for resource
3099 reporting yet), and demonstration client.
3101 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3103 --- 1.0b3 1995/08/24
3105 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3106 handled incorrectly when records were requested in the searchResponse. This
3107 will only affect you if you use the frontend-server.
3109 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3110 Test-client will ask for and print GRS1. Ztest will return dummy records
3113 Added Explain encoders/decoders to the service-level API. Untested.
3115 Added Extended Services: Item Order encoders and decoders to the Service-
3116 level API. Untested. We could use a recent copy of the pertinent bits
3117 of the ILL protocol to add those bits.
3119 Added diagnostic format 1 encoders/decoders to the service-level API.
3122 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3123 odr_cons.c, which causes a more correct output.
3125 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3126 was always set to 0 when no records were requested in the searchRequest.
3128 * Added better external-handling. This shouldn't harm old code that
3129 *encodes* externals. It can break code that looks for a
3130 'single-ASN1-type' representation, since those types that are known
3131 are now decoded immediately. Look at the SUTRS sample code in
3132 seshigh.c and client.c. Documentation updated.
3134 Handling of structured records in bend_fetchresponse. Length -1 marks
3135 structured record, type is deduced from format field.
3137 --- 1.0b2 1995/06/27
3138 Fairly quick maintenance release to add SUTRS support.
3140 Fixed handling of SUTRS records in the demonstration client.
3142 * Added format field to the bend_fetchrequest and bend_fetchresponce
3143 structures of the backend API (frontend server). When the record is
3144 returned, the value of the format field is mapped to an OID. The
3145 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3146 of the record. The special value VAL_NONE in the bend_request means
3147 that no specific format was requested by the client. Documentation
3148 updated accordingly. Test server (ztest) will return a fixed dummy
3149 SUTRS record if your client requests SUTRS.
3151 Documentation updated accordingly.
3153 You can now set external libraries and RANLIB support in the top-level
3157 First public release.
