3 Build YAZ for Ubuntu Oneiric.
5 CCL: allow parantheses for proximity operands. For example CCL query
6 (a) % (b) is now allowed.
8 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
9 marked dead, rather then being destroyed. If not, the session memory is
10 being free'd before the search/scan handler is finished. Also destroy
11 'request' memory in request_release rather than in various places,
12 which resulted in leaks from time to time.
16 cql_sortby_to_sortkeys: honor sort prefix.
18 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
19 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
20 The rpn2cql family of functions now always returns quoted CQL terms.
22 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
26 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
27 sequence is treated as one. For example, &&a=b&&&c& is identical to
32 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
33 APDUs for a connection to a WRBUF.
37 Fix cql_sortby_to_sortkeys. Completely broken before.
39 Make CCL's @truncation work again.
43 New ZOOM connection setting: tproxy. It's like proxy, but does not
44 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
45 to set resolved address + port for a connection outside ZOOM itself.
47 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
51 Fix uninitialized variable in Solr spell support (could cause SEGV
52 for SRU response decoding).
54 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
55 back-end's addinfo through into the ZOOM response addinfo.
57 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
58 they are separated by a colon and a space rather than simply
63 Add support for Solr spell-checking/suggestions through ZOOM.
64 If a Solr target has been configured correctly for spelling-checking
65 and suggestions, these will now be returned on the ResultSet option
66 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
70 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
71 with a flag whether to substitute escape sequences or not.
75 Fix nmem_strsplit_escape to substitute escape char properly.
77 New option for zoomsh -e , which makes it abort on first error and
78 return process exit code to indicate success/failure.
80 YAZ options utility supports special option -- which makes all it treat
81 all following arguments as non-options.
85 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
86 searched if absolute filename is given.
88 Fix conv_xslt() error-reporting when stylesheet is not found.
89 (The value of fullpath is meaningless in this situation.)
93 Fix problem in CQL sort node creation: un-initialized memory.
95 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
96 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
97 CQL sortby depending on whether Type-1 or CQL is actually sent to the
100 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
101 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
103 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
104 will make it possible to use both single-character mask (#) and wildcard (?)
105 in CCL . Throw diagnostic for left truncation because that is not supported
108 --- 4.2.13 2011/09/01
110 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
111 cases using escapes (\-sequences) and masking.
113 PQF parse fix: A trailing backslash followed by end-of-string (\0)
114 would result in a read one byte beyond string.
116 rpn2ccl may use Z39.50 masking for terms (t=z).
118 ICU check fix. Don't include library -lCrun on Solaris, unless present.
120 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
121 not --cppflags (which seeems like an error in icu-config).
123 --- 4.2.12 2011/08/27 RPM package only
125 cql2ccl: fix conversion of terms: operator characters were not
128 --- 4.2.11 2011/08/25 RPM package only
130 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
131 CCL parser will map both # and ? to their regular expression
132 quivalents (. and .*).
134 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
135 of reserved CQL characters.
137 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
138 is, so that they are passed through.
140 --- 4.2.10 2011/08/24
142 ZOOM SRU mode: more aggressive re-connect.
144 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
145 made available as a utility function, declared in <yaz/logrpn.h>
147 rpn2cql_structure() supports proximity nodes (except that the Type-1
148 proximity node's "exclusion" binary is ignored, as there is no way to
149 express that in CQL). Fixes bug #4564.
153 Fix SEGV that could occur if set command of zoomsh was given without
154 value (2nd argument).
156 Fix SEGV that could occur if unsupported transport was given for
157 COMSTACK - say https (when SSL was unavailable).
159 Build yaz-url on Windows too.
163 New utility to get web content. Header is url.h. A command line tool
164 yaz-url is part of the distribution and packages.
166 Fixes for SSL COMSTACK (when gnutls is in use).
168 New functions yaz_base64{encode,decode}. Header is base64.h.
172 ZOOM C includes HTTP response buffer as additional info if it fails
173 to decode the SRU response.
175 Make wrbuf_json_puts available.
179 zoom: throw diagnostic for invalid value for option "sru". Before a
180 bad SRU request was sent.
182 Adding new utility wrbuf_vp_puts.
184 Add cclxmlconfig.obj to win/makefile. It was missing completely.
188 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
189 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
190 redirect was used at the same time.
192 MARC line mode decoding: be less picky about length given - first
193 5 digits of header that is.
195 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
197 Changes to decoding of SRU records: a record with recordPacking=xml is
198 modified with a new root element <yaz_record> if the recordData contains
199 multiple children elements. This is to make the record XML parseable
202 RPN to SOLR conversion: encode special characters.
204 Generic Frontend Server: fix uinitialized member, stepSize.
208 Fix a bug in SRU decoding of records.. The database records stored
209 had un-initialized memory, but it would only be seen with yaz_record_render
210 and type_spec="ext" .
212 Fix a bug in ccl_qual_dup introduced in 4.2.3.
216 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
220 Add new utilities to convert from CQL to CCL . These utilities have
221 prefix cql_to_ccl defined in cql.h.
223 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
224 lead to memory heap corruptions when ICU utilities were in use.
228 Make compilation work without Libxml2.
230 yaz-client: remove redundant blanks in display of searchResult-1 term
235 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
236 resulting CQL node (tree) in a new node CQL_NODE_SORT.
238 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
239 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
240 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
241 Note that the CQL sortby spec is only converted when the GFS is already
242 converting from CQL to RPN (cql2rpn element).
244 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
245 specify whether to collapse delimitors or not. The existing nmem_strsplit
246 do collapse (collapse parameter = 1).
248 Windows installer: For NSIS, set InstallDir depending on x86/x64.
250 Rename internal func yaz_use_attribute_create. While non-static, this
251 function is not declared in a public header.
255 Add -lCrun when linking with ICU on Solaris.
257 More quicks character set conversions for OPAC records.
261 fix problem with record_render: records were converted (character set
262 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
266 SRU: add methods for handling DADS SRU-proxy facets.
268 Separate OPAC record character set for ZOOM_record. yaz_record_render
269 allows a character set given as charset=from/opacfrom,to where 'from' is
270 the character set of a bibliographic record, 'opacfrom' is character set
271 of OPAC record and 'to' is the target character set.
275 yaz-client: show may XML format records. Command show followed by 'format'
276 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
279 src/stemmer.c: Avoid using unnamed union. It is not supported by some
282 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
285 Update yaz.spec to operate on both SLES11 / Centos 5.5.
287 RPM: Release includes 'indexdata' name. Use indexdata in release name so
288 this package can be distinguished from other vendors.
290 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
291 as determined by configure
293 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
295 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
296 returns no error and no record, the present request is considered
297 partial (only a subset of the records could be returned by backend), and
298 so it is appropriate to set Present Status to partial-4.
302 Move yaz-config man pages to section 1.
304 More documentation about SOLR.
306 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
307 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
308 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
309 peers on some Linux systems. However, in general that does not work
310 so YAZ can not rely on that to work. Debian changed behavior in this
311 respect from Debian lenny to Debian squeeze (still testing as of Oct
313 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
315 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
319 Fix yaz-config output: echo_source not set correctly by configure.
323 SOLR WebService support for yaz-client and ZOOM.
325 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
327 --- 4.0.12 2010/08/17
329 Z39.50 facet support. Facet specifications are passed for search in
330 other-information with ASN.1 as defined in facet.asn and OID
331 .10.1000.81.5 . Facets are expressed as an Attribute list as known
332 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
333 3 is limit (number of entries to get in response). yaz-ztest returns
334 dummy facets if a client asks for them.
336 --- 4.0.11 2010/07/09
338 CCL fixes: bug 2895 and bug 3539.
340 GR1-display: add comma in display - was removed by mistake in
343 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
345 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
347 --- 4.0.10 2010/06/18
349 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
350 result set from a connection. The result set will be on its own
351 thereafter; no operations on it will perform retrievals from a target.
352 Only cached copies are returned.
354 ZOOM C:fix case for HTTP servers responding with Connection:close.
355 Ensure that if there is a current task it is resumed (like fetching
356 more records in a result set) . Bug #3484.
358 PQF parser: use odr_atoi for Odr_int (not atoi)
360 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
361 values that contain any non-digits are treated as string attributes
362 (previously decoding only checked for leading character ([0-9]). PQF
363 encoding: attribute string values are not surrounded by double-quotes.
367 New utility for managing threads - thread_create.h.
369 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
370 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
371 but YAZ' implementation do.
373 Fixes for yaz_cond-functions on Windows 7.
375 DLL export more symbols.
377 zoomsh: show record do NOT render opac.
379 Remove *.la files from Debian and RPM packages.
383 Debian package libyaz-dev depends on libgnutls-dev again (was
384 removed in YAZ 4.0.6, but due to Libtool it is still needed
385 even though yaz-config do not list libgnutls libs).
387 ZOOM: Use only one WRBUF for returning string results for
388 ZOOM_resultset. Reduces memory usage for ZOOM in general.
390 ZOOM: ZOOM_connection do not use a shared pointer to
391 ZOOM_resultset after ZOOM_resultset is destructed by
392 user. Reverts to YAZ 4.0.4 behavior.
396 record-conv: fix problem with at least one XSL conversion -
397 due to probably incorrect usage of XML XSL documents.
401 Fix yaz-config for static mode and the use of SSL (gnutls).
405 Forward decl timeval struct in mutex.h and gettimeofday.h.
407 yaz-config: fix 'static' mode linking.
411 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
412 are wrappers for pthreads or Windows. For Windows these are put in
413 a separate DLL: yaz_cond4.
415 libyaz.la (whole source) is compiled with thread. If thread support
416 is enabled enabled, all source of YAZ is compiled with treading support.
417 This allows core utilities such as yaz_log to use thread facilities.
418 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
419 thread utilities. This commit moves mutex utilities (mutex.c) from
420 libyaz_server.la to libyaz.la.
422 yaz-json-parse displays leading text until error.
426 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
427 patch from Giannis Kosmas.
429 SRU: no longer URL encode SRU database. The URL for an SRU server is
430 a URL and such is alreeady encoded - at least when given with leading
431 http:// or https://. This reverts behavior to YAZ 3.0.50.
433 Support for new MARC XML notation TurboMARC which like MARCXML is a
434 complete representation of MARC/ISO2709.. This one, however, is more
435 compact and allows for faster processing with XSLT. TurboMARC can be
436 used in the marcdisp.h API, from the yaz-marcdump utility and from
439 yaz-ztest can be configured - via the database - to perform certain
440 delays when it performs operations search, present and single record
441 fetch. This allows testers to make yaz-ztest act as a real or even slow
442 Z39.50 server. Refer to the yaz-ztest man pages for details.
446 wrbuf_destroy allows NULL WRBUF passed to it.
448 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
450 Add ZOOM_connection_close.
452 No fixed size buffers for ZOOM shell - bug #3257.
454 tstodr: make it work on s390 platform.
456 New icu iterator-functions. The new icu_iter-functions makes it possible
457 to use ICU chains from many threads.
459 yaz-client: better syntax check for show command.
463 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
466 New simple local-file XML include facility which allows file glob-patterns.
467 Refer to yaz/xml_include.h.
469 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
472 ZOOM_record_get supports new parameter "format" which makes it format XML
475 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
476 JSONText in ECMA-262) is JSONValue, not JSONObject.
480 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
481 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
483 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
484 POSIX/Unix builds .so with major version 4.
486 Remove old LOG_-defines from log.h. They have been obsolete and
487 undefined by default for the last 5 years.
489 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
491 GFS: Remove socket (int *fd) from search_rr handler. The socket
492 descriptor ptr is a facility that allowed a search handler to supply
493 a socket which would serve as a callback - when search was complete.
494 This facility has now been in use for years.
496 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
497 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
498 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
499 returns 'const char *' rather than 'char *. The returned string is
500 read-only and should not be modified by applications. COMSTACK cs_close is
501 now a void function - it no longer returns int. No applications check for
502 the value and the implementations has always returned 0.
504 ZOOM: use size_t for scan hit counts and str size. Functions
505 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
506 occ (hit count) and len (string length) are now of type size_t pointer
507 rather than int pointer. This is to be able to represent large hit counts
508 and to also just to use the proper type for string length (strlen result).
510 New JSON parser. Refer to include/yaz/json.h .
512 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
513 Used to be int in some cases. Many wrbuf_-functions used to return an int
514 indicating some length.. These return values were never used. And so they
517 ODR: odr_malloc, odr_total now takes size_t for size.
519 clone_z_type: fix leak; occurred for encoding failures.
521 --- 3.0.52 2009/12/03
523 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
524 bug was introduced in 3.0.51.
526 --- 3.0.51 2009/12/02
528 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
530 tcpip comstack: fix leak for getaddrinfo.
532 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
533 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
534 Decoding of SRU "path" database is performed by private function
535 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
536 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
538 yaz-client: honor base command for SRU. Change when database setting
539 is applied for SRU and ensure it is kept when a connection is reset.
540 Change also the way errors are displayed or SRU (decoding of packages).
542 --- 3.0.50 2009/11/02
544 Add support for extra request / response data for SRU codecs and GFS.
545 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
546 for extra data response buffer and length. For the GFS, both request
547 and response data (XML) is carried in extra_args and extra_response_data
548 for the search handler. Patch by Ko van der Sloot.
550 ZOOM: For queries that cannot be converted to the specified rpnCharset,
551 ZOOM now returns a diagnostic on the client-side ('invalid query' /
552 10010). This fixes bug #2113.
554 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
555 cmdfile included a 'quit' command that would result in a memory violation.
557 --- 3.0.49 2009/10/01
559 Make a number of functions defined in xmlquery.c static. These have
560 never been declared in a public header file (yaz/xmlquery.h) and was
561 made public by mistake.
563 Improve speed of character conversions (iconv utilities). This makes
564 conversions from MARC-8 faster.
566 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
567 unless type desired is "raw". This will prevent type "xml" from
568 returning ISO2709 .. Which obviously can not be XML parsed.
570 Fix memory leak in ZOOM that would occur if option apdulog was used
571 on a re-used connection.
573 Frontend server logs HTTP requests.
575 Frontend server now sends Z39.50 close when it times out (sesssion has
576 been idle for too long). Versions 2.0.30 and earlier also sent close.
577 But due to a mistake this was disabled in all versions after that, i.e.
578 the server would just close the socket immediately.
580 yaz-client emits a better message when receiving an unrecognised
581 userInformationField.
583 Skip zero-length subfields when decoding ISO2709. This rare case happens
584 if a record has two FS characters in a sequence. Without this patch
585 there would be a reference beyond char array in using_code_len fragments
588 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
590 --- 3.0.48 2009/08/28
592 The show command offered by the zoomsh command now takes a 3d optional
593 parameter type which is what is passed to ZOOM_record. If the type
594 argument is omitted, "render" is used.
596 RPN to CQL conv may use USE string attributes (bug #2978).
598 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
600 --- 3.0.47 2009/07/08
602 Function yaz_xml2query allows a diagnostic element in the PQF XML
603 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
604 code and additional info respectively.
606 The BER BOOLEAN is now the integral type Odr_bool which still happens
607 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
608 typedef'd to Odr_int. This is still an integral 'int', but it may be
609 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
610 ASN-1 compiler as well as programs has been updated to use the new types.
612 --- 3.0.46 2009/06/08
614 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
615 only the bibliographic record was rendered. For type=opac, an OPAC
616 record is only returned if it is present.
618 iconv: small fix for encoding of advancegreek.
620 yaz-client: avoid double display of SRU/SRW records (bug #2798).
622 yaz-client: option auto_reconnect=on really reconnects.
624 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
626 server: avoid null ptr ref for for yaz_poll errors.
628 build: fix RPM build for RHEL 5.3.
630 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
632 --- 3.0.45 2009/03/31
634 Fixed bug #2709: TCP connect returns Invalid argument.
636 Fixed compilation for mingw.
638 Honor charset for raw records (ZOOM_record_get).
640 Fixed use of errno for threaded mode that was seen on Solaris 10.
642 Fixed argument passing with blanks in value for Windows Service.
644 Disable YAZ' own log rotate by default (no 1 GB limit).
645 The variable l_max_size which specifies the log file limit is set to 0
646 (DISABLED): This is due to the fact that YAZ is most often deployed using
647 logrotate. Also YAZ can not perform log rotate because of unsufficient
648 permissions (setuid).
650 --- 3.0.44 2009/02/17
652 List supported encodings in man page for yaz-iconv.
654 Fixed missing SSL libs for --libs output
656 Re-established OID record syntax application-xml. Nobody should use it
657 but we don't want to change soname because of this symbol being absent.
659 --- 3.0.42 2009/02/02
661 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
663 Added member named_result_sets for init handler struct for the GFS. This
664 allows a server to disable named result sets.
666 Removed OID record syntax application-xml.
668 Added support for rule-based transliterator for ICU wrapper of YAZ.
670 Fixed bug #1902: yaz-icu XML output.
672 Make YAZ checks Emacs friendly.
674 BITSTRING value shows value. Bug #2346.
676 ISO2709 decoding: skip control characters from indicator data.
678 Omit sort key by default in yaz-icu's output.
680 Allow combined single char options (again) for YAZ' options function.
682 Utility yaz-marcdump got option to display YAZ version (-V).
684 Allow YAZ to use ICU 3.4.
686 Added new ICU test case which illustrates removal of diacritics.
688 --- 3.0.41 2008/12/29
690 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
692 --- 3.0.40 2008/12/29
694 For configure, using option --without-xml2 also disables Libxslt/Libexslt
697 Fixed bug #2352: yaz-marcdump crashes for certain record.
699 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
701 Added support for Danmarc2 to UTF-8 conversion.
703 Added support for ISO5426 to UTF-8 conversion.
705 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
706 implementation version.
708 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
710 --- 3.0.38 2008/11/10
712 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
713 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
715 ZOOM C now interprets databaseName option for ZOOM connection as path
718 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
720 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
722 Dummy Libxml2 types no longer defined in headers of YAZ'.
724 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
727 --- 3.0.36 2008/09/26
729 Various ODR chapter fixes.
731 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
733 Added missing source for Windows compilation, mutex.c.
735 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
737 For SRU connections in ZOOM all records up to "count" are now fetched.
739 Fixed crash in generic frontend server (and yaz-ztest) which occurred
740 in Windows due to bad error handling for Libxml2.
742 Added facility for sending arbitrary records (ASN.1 any) using
743 ZOOM C's Extended service update. Patch by Sam Reynolds.
745 New options for ZOOM C's connection, logapdu which makes ZOOM log
748 --- 3.0.34 2008/06/18
750 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
752 --- 3.0.32 2008/06/12
754 Fixed memory violation that could occur when decoding UTF-8. This bug
755 was only present in 3.0.30 of YAZ.
757 --- 3.0.30 2008/06/06
759 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
760 GNU TLS is used by default (if found).
762 yaz-ztest returns OPAC records if a client asks for OPAC.
764 Improved speed of MARC-8 encoding.
766 Added support for lossy and loss-less MARC-8 encoding.
768 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
770 Added new Windows Service wrapper (sc).
772 yaz-client's itemorder command may now send a file.
774 Fixed yaz-marcdump to allow the use of NS prefix for record element.
776 Added new function yaz_log_xml_errors.
778 Allow (but warn) unknown XML attributes in MARCXML parsing.
780 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
782 The UTF-8 to MARC-8 conversion now uses a different set of characters
783 for Greek symbols. Bug #2120.
785 --- 3.0.26 2008/02/21
787 Added yaz_daemon (daemon.h).
789 Fixed bug #2068: pkg-config trouble
791 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
793 --- 3.0.24 2008/01/28
795 Document --with-xml2 option.
797 Added OPAC XML XSD (etc/opacxml.xsd).
799 Allow glob mask for name attribute in retrieval element for the
800 generic frontend server's retrieval facility.
802 Changed yaz_poll_poll to return yaz_poll_except for all returned events
803 except POLLIN/POLLOUT.
805 Fixed error handling in cs_listen. Bug #2037.
807 --- 3.0.22 2008/01/20
809 Fixed version in yaz/yaz-version.h.
811 Fixed bug #2027: Crash when closing connection.
813 Changed configure so that ICU support is only enabled if only ICU
814 and Libxml2 is available (because the ICU chain is XML based).
816 --- 3.0.20 2008/01/15
818 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
819 is built. Only this DLL depends on the ICU runtime.
821 yaz-ziffy is no longer part of YAZ. It is distributed separately by
822 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
824 Changed license of CCL module to 'Revised BSD'. After consultation with
825 remaining members of the original EUROPAGATE consortium, we are re-issuing
826 the CCL module without a separate license. The software was developed by
827 Index Data as part of a research project. The special license was included
828 to help feed usage information back to the project consortium to support
829 project evaluation. At this time, the project consortium has long-since
830 disbanded, and the majority of the original principals have retired. At the
831 same time, we have significantly modified the software during the following
832 years, to the point where very practically no original code remains. To
833 simplify re-use of the software, we have contacted those members of the
834 consortium who could be reached, and agreed to re-issue the module as a
835 proper part of the YAZ package.
837 Tcl scripts uses /usr/bin/tclsh as preferred shell.
839 CQL closer to being version 1.2 compliant. CQL also allows free-form
840 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
843 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
844 bug could make Extended services handling crash in the ZOOM layer. This
845 bug was only present in YAZ 3.0.18.
847 --- 3.0.18 2007/12/19
849 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
852 yaz-marcdump reads and writes collection wrapped records.
854 Handle OPAC for record conversion module.
856 Fixes for ICU wrapper.
858 Allow ICU libs to be controlled with --with-icu .
860 --- 3.0.16 2007/11/12
862 Added yaz_poll which is a wrapper for select/poll. When poll is available
863 and non-buggy, it is used, by yaz_poll . This allows more than 1024
864 sockets to be in use.
866 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
867 functionality through an XML based configuration (ICU chain). This system
868 is useful for search facilities such as Pazpar2 and Zebra that needs to
869 perform tokenization of indexed material. The ICU code in a separate
870 library libyaz3_icu.a.
872 Added HTTP tunnel facility for COMSTACK, bug #1752.
873 This is a facility that allows a Web proxy, such as squid, to tunnel
874 Z39.50 traffic. This facility is "transparent" to must applications
875 using YAZ. It's enabled by using pseudo transport connect: followed by
876 the proxy address, followed by command, then follwed by he regular
877 "virtual" addresss. For example,
878 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
880 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
882 --- 3.0.14 2007/09/21
884 Fixed bad memory reference in ZOOM_record - cuased by member not being
885 initialized. This was a problem only in YAZ 3.0.12.
887 Fixed bug in conversion from MARC to XML: Non-XML characters in control
888 fields were not removed.
890 Changed the way C code is generated from codetables.xml. Made a MARC-8
891 conversion trie for each characterSet section rather than codeTable.
892 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
893 of codetables.xml from Larry Dixson, LOC. Bug #1464.
895 --- 3.0.12 2007/09/12
897 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
898 from ZOOM_record_error).
900 ZOOM C function ZOOM_record_get returns record schema for type="schema".
902 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
904 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
906 Better SRW-to-Bib-1 diagnostic mapping.
908 ZOOM C and yaz-client announces SRU version 1.2 by default.
910 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
913 Fixed in yaz_sru_decode to allow other version than 1.1.
915 --- 3.0.10 2007/08/22
917 Added support for SRU scan for ZOOM.
919 Added support for the use of the older versions or Extended Service
920 Update in ZOOM. To faciliate this, an option "updateVersion" may be
921 set to the version , 1=first, 2=second, 3=third. The third version is
922 what ZOOM C has used so far. And that, obviously, is the default.
924 Added support for CCL queries in Z39.50 queries sent to the GFS (and
925 therefore in Zebra and in SimpleServer-based applications). The new
926 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
927 qualifier file used to transform incoming CCL queries into Type-1 RPN,
928 which is passed into the back-end search callback function.
930 Added support for HTTP Basic authentication in clients: the SRU/W
931 codec encodes the username/password elements of the PDU structure
932 appropriately, and these may be set using the "user" and "password"
933 options in ZOOM-C applications (the same options that are used for
934 Z39.50 authentication).
938 Fixed bug #1208: SSL appears to be broken in ZOOM.
940 Fixed bug #1206: Libxml2 include path weirdness.
942 Added oid_name_to_dotstring.
944 Allow elementSetName to be specified for ZOOM C record update.
946 Allow waitAction to be specified for ZOOM C based for Extended Services.
948 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
949 syntax OID. Bug introduced in YAZ 3 series.
951 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
955 Fixed bug #1157: yaz-client does not read .yazclientrc from current
956 directory. yaz-client now reads commands from file given by option -f
957 if specified; then tries to read .yazclientrc in current directory.
958 Failing that, it reads .yazclientrc from user's home directory.
960 Added support for correlationInfo Note and ID for Record Update via
963 Added yaz-client command querycharset which specifies character set for
964 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
965 (termListAndStartPoint).
967 Charset ISO5428:1984 is an alias for ISO5428-1984.
969 Implemented a way to perform scan in a result set using Z39.50. This
970 is achieved by attaching the result set name in the characterInfo
971 (type InternationalString) of OtherInformation in the Scan Request PDU.
972 The result set is identified in the otherinformation by the new OID:
973 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
974 This allows for scan in result set and faceted search . Zebra did some
975 of this in the APT term using attribute type 8 and value being result
976 set. Using the OtherInformation approach for this is cleaner and easier
977 to work with in proxies and the like. This facility can be used in
978 yaz-client using new command setscan which takes a result set as first
979 argument, start position (APT) as second.
981 Changed decoding of SRU XML packed records to deal with servers that
982 have recordData with XML data with multiple root nodes. Also make
983 comparison for recordPacking case insensitive. Again, one server
984 returns "XML" where others return "xml".
986 For SRU responses allow Content-Type application/xml as well as text/xml.
990 Fixed bug in character set conversion of BER strings. Bug introduced
995 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
997 For OID class, use oid_class consistently.
999 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1002 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1003 character set for bibliographic information interchange". By Giannis Kosmas.
1005 Added documentation on new OID API.
1007 --- 3.0.0 2007/05/02
1009 Changes to generic frontend server interface: added new member
1010 'query_charset' for bend_initrequest structure. A backend init handler
1011 should set this member to its native character set for query terms.
1012 When defined, the frontend server logic will announce this character set
1013 to a client if the negotiationModel bit is set by the client. All server
1014 implementors are encouraged to specify this. If a backend server does not
1015 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1017 Added CCL utility to remove terms (stop words) from resulting RPN
1018 tree. This is handled by functions with prefix ccl_stop_words_ .
1020 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1021 terms in RPN queries.
1023 Clean-up the CCL API. Moved some internal structures from ccl.h to
1024 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1025 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1026 This is replaced by ccl_parser_find_str which takes a string instead.
1028 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1029 libyaz.la is the core of YAZ except the generic frontend server and
1030 does not depend on POSIX threads anymore. libyaz_server.la is the
1031 generic frontend server facilities and uses POSIX thread functionality
1032 if available. The libyaz.la no longer depends on POSIX threads because
1033 the number of global structures is limited. NMEM no longer re-uses blocks
1034 between threads ; it simply free's memory immediately but allocates in
1035 "large" chunks as usual. We don't expect any performance penalties
1036 because of this. The yaz_log system is still using a global log_level so
1037 caution must be taken when modifying it with yaz_log_init_.. +
1038 yaz_log_mask_str. This, however, should not cause any trouble because
1039 these functions are called during initialization of application code
1040 anyway. `yaz-config --libs server` returns libs for server applications;
1041 `yaz-config --libs` returns libs for non-server applications.
1043 New OID database - with public definitions in oid_db.h. Removed old OID
1044 database including the head oid.h and definitions such as enum oid_value
1045 and struct oident. The new OID database uses the same string names as
1046 before but the 'protocol' is gone. There are now only two representations
1047 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1048 converts from string to OID; functions with prefix yaz_oid_to_string
1049 converts the other way.
1051 Change to emit_term() in CQL-to-PQF query translation: when a term has
1052 the /regexp relation modifier, do not process it for leading and
1053 trailing "^" and "*", which have quite different meanings in regular
1056 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1057 write handlers no longer carries a 'last' parameter. This will make
1058 yaz_iconv flush "less" characters. A flush is performed by call to
1059 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1061 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1062 removed, because function yaz_query_to_wrbuf does the same.
1064 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1065 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1067 Deprecated MARC utility functions removed.
1069 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1072 Branch split: YAZ_2_1_55_branch
1074 --- 2.1.54 2007/03/16
1076 Fix to ZOOM-C so that transparent reconnection is properly handled on
1077 connections that are in asynchronous mode.
1079 Fixed compilation on OpenBSD 4.0.
1081 Large strings in GRS-1 records are now properly displayed in yaz-client.
1083 Added character conversion support for "advancegreek"; based on patch from
1086 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1087 sequence is met. Before the error was not set so it would be unknown.
1089 Adjust yaz-marcdump MARC reader so that it skips until record separator
1092 --- 2.1.52 2007/03/07
1094 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1095 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1096 fd_set structure used as a bitmask for the FDs to be selected on.
1098 Using ACX_PTHREAD macro to check for POSIX threads.
1100 Fixed have-vsnprintf check.
1102 --- 2.1.50 2007/02/23
1104 Fixes for configure on BSD. Bug #900.
1106 Added snprintf/vsnprintf wrappers for systems that don't have
1107 limits (heavens forbid).
1109 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1110 created before all previous tasks were completed and removed from the
1111 task queue, the new task could be removed by a mistake.
1113 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1115 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1117 Fixed bug #832: Problem with MARC/charset in yaz-client.
1119 Fixed bug #668: save command line history for yaz-client.
1121 Fixed bug #830: pkg-config support.
1123 --- 2.1.48 2007/01/23
1125 Extended ZOOM result set options with two options that may be read by
1126 a client: resultSetStatus and presentStatus with values as specified for
1128 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1130 Fixed bug #827: Using SSL fails on Debian etch.
1132 Fixed bug #826: Weird looking chars for set of MARC records.
1134 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1135 that is treated as an ItemOrder with itemRequest being an XML document
1136 external. The value of "doc" is the content.
1138 Extended the GFS search facility. New member of bend_search_rr
1139 'estimated_hit_count' signals that hits is known to be an estmate
1140 (higher or lower than real hit count). New member 'partial_resultset'
1141 signals that the search was partial (hit count is lower or equal than
1142 real hit count). For Z39.50, the information is stored in resultSetStatus
1143 member of SearchResponse APDU. For SRU, the information is signalled
1144 via SRU diagnostic 59: "Result set created with valid partial results
1147 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1149 --- 2.1.46 2007/01/13
1151 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1153 Added ZOOM_connection_peek_event.
1155 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1156 the following new functions:
1157 ZOOM_event_nonblock, ZOOM_connection_process,
1158 ZOOM_connection_get_{socket,mask,timeout},
1159 ZOOM_connection_fire_event_{timeout,socket}.
1160 The existing blocking event handler, ZOOM_event, is a wrapper for the
1161 + blocking ZOOM_event_sys_{poll,select}.
1163 Implemented function ccl_xml_config which parses XML version of CCL
1164 configuration (bug #798).
1166 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1168 Added timings utility (yaz/timing.h)
1170 --- 2.1.44 2007/01/03
1172 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1175 Fixed bug #779: Rotation of apdu.log fails.
1177 Fixed for character set conversions:
1178 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1179 Honor G1 set in MARC-8 decoding.
1181 --- 2.1.42 2006/12/17
1183 Fixed bug #775: char conversion does not handle Alternative UTF-8
1186 Implemented function yaz_marc_read_line which parses MARC line format
1187 records. There is a wealth of formats out there. So far, this function
1188 reads line records produced by yaz_marc_write_line.
1190 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1191 more generic and easier to remember(!) options: -i format and -o format
1192 which specifies input format and output format respectively - where
1193 format is one of "marc", "marcxml", "line", "marcxchange".
1195 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1196 does not print anything except warnings for records.
1198 For yaz-marcdump, added support for MARC split into files (-s) with a given
1201 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1202 spec, at http://www.loc.gov/standards/sru/record-update/
1203 This has changed the binary layout of the following structs:
1204 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1205 bend_update_rr . Patch by Ko van der Sloot.
1207 Added GFS utility function bend_assoc_is_alive which returns 1 if
1208 association is still alive (client is connected); 0 otherwise (client
1209 closed connection). This allows busy servers to stop working for
1212 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1213 been a separate piece of software. This version of ziffy has been modified
1214 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1216 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1218 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1219 Client code may now interrogate options such as "init_opt_sort" to
1220 find out whether the server claims to support various options.
1222 --- 2.1.40 2006/11/27
1224 Added utilities yaz_{set,get}_esn to set/get element set name from
1227 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1228 of YAZ and has been so since YAZ 2.1.10.
1230 Implemented ZOOM_record_error which returns error information for
1231 record (surrogate diagnostic).
1233 --- 2.1.38 2006/10/31
1235 Updates for SRU Update by Ko van der Sloot:
1236 1. Changed name from "operation" to "action"
1237 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1238 versions in the code, marked as 'backward compatible'.
1239 3. Added diagnostics for SRU Update.
1241 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1243 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1245 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1247 For GFS, fixed problem with SRU diagnostic 'First record position out of
1248 range' being issued for 0 hits.
1250 zoomtst10 part of Windows Build.
1252 --- 2.1.36 2006/10/13
1254 Implemented yaz_filepath_comp which splits a path into file path
1255 components (required by Zebra 2.0.3+).
1257 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1258 BSD inspired license until now so this should not have any real impact on
1259 anybody. See http://www.opensource.org/licenses/bsd-license.php
1261 Fixed bug #687: Missing log lines.
1263 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1266 Fixed bug #689: SRU diagnostics to be added.
1268 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1269 whether a connection is idle (no more work do do).
1271 --- 2.1.34 2006/10/04
1273 Change type of optval from long to int for invocation of setsockopt with
1274 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1276 Added support for specifying the max log file size for the Generic
1277 Frontend Server. The size is given with option -r.
1279 --- 2.1.32 2006/09/21
1281 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1283 --- 2.1.30 2006/09/17
1285 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1288 Fixed bug in Generic Frontend Server that could cause a server to stop
1289 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1291 For the generic frontend server, the maximum record size is used as maximum
1292 size of incoming packages (SRU + Z39.50). The value until was previously
1293 only used in Z39.50 Init negotiation and, later, in a session controlled
1294 sizes of records returned. This is controlled using -k option. It can be
1295 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1297 --- 2.1.28 2006/09/04
1299 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1302 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1304 New option for yaz-marcdump -lpos=value which allows setting a portion
1305 of MARC header to a certain value.
1307 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1309 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1310 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1312 --- 2.1.26 2006/08/15
1314 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1317 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1319 --- 2.1.24 2006/08/08
1321 Fixed MARC ISO2709 encoding routines to deal with character set
1324 Minor changes to GFS logging. Database included in search request log
1327 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1328 cached/multiple records.
1330 Shared libraries are built by default on Unix+configure.
1332 Changed cql2pqf transformation to use a different evaluation order. The
1333 new order is: always, relation, structure, position, truncation, index
1334 and relationModifier. Old order was: always, relation, relationModifier,
1335 structure, index, position, truncation. Note that the the latter ones
1336 override former ones for identical attributes.. The new scheme means that
1337 it is possible to override any existing attribute with a relationModifier.
1338 And also that it is possible to override everything for the index rule
1339 (except the ones listed in relationModifier). No order is perfect but this
1340 one, we believe, covers more real cases.. The "always" should have been
1341 called "default", since the attributes there can be overridden with all
1344 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1345 compilation phase, but also for yaz-config --cflags output. This allows
1346 us to have public headers with Libxml2 stuff in them . It should also,
1347 eventually, make Libxml2 checks redundant in packages using YAZ, such
1350 --- 2.1.22 2006/06/15
1352 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1353 stored in uri, message and details.. Previously diagnostics were stored
1354 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1355 compatibility.. but he's probably the only one affected, so.
1357 Added support for CCL, compiled on the client side, in ZOOM-C. This
1358 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1359 input; the resulting query objects can be used for for searching with
1360 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1362 YAZ' configure searches for OpenSSL by default.
1364 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1365 SL_CTX_use_certificate_file. See
1366 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1367 for more info. Thanks to Ko van der Sloot.
1369 --- 2.1.20 2006/06/02
1371 Bug #600: SRU GET, POST support for yaz-client. Introduced
1372 command 'sru' which selects method SOAP/GET/POST.
1374 Allow missingValueAction to be specified for the sortspec string -
1375 function yaz_sort_spec. By default, the missing value action is null.
1376 Use ! to specify "abort". Use = followed by stringvalue to specify default
1379 Ensured that Present-handler (if defined) is called in GFS before any call to
1380 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1381 searchRetrieve requests.
1383 Documentation for YAZ is now based on the Docbook XML/XSLT using
1384 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1385 is no longer depending on jade/openjade or docbook-to-man scripts.
1386 PDF is no longer part of the distribution - but can optionally be
1387 made using DSSSL/jadetex or FOP.
1389 Added retrieval handling support in Generic Frontend Server to support
1390 conversion between MARC/XML as well as XSLTtransforms. See
1391 etc/yazgfs.xml for an example.
1393 Added Authentication support to Generic Frontend Server in SRU
1394 mode. Authentication using HTTP Basic is supported, as is the use
1395 of 'x-username' and 'x-password' parameters in the request itself.
1397 Added support for a new character set MARC8s identical to MARC8 except
1398 that it converts combined characters to single Unicode characters in the
1399 Latin-1 range (when possible).
1401 --- 2.1.18 2006/04/24
1403 ASN.1 compiler 0.4: generates brief Doxygen file header for
1404 generated .h/.c files.
1406 Utility yaz_iconv now supports conversion to MARC-8.
1408 New facilities for the MARC module. The reading - and writing of
1409 content are separate methods for the yaz_marc_t handle. The following
1410 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1411 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1412 format). Write functions have prefix yaz_marc_write_.. The existing
1413 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1414 available. Removed support for OAI-MARC and simplexml (not the
1415 simplexml from PHP5).
1417 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1418 to be returned for this connection.
1420 --- 2.1.16 2006/03/31
1422 Allow multiple languages and charsets to be specified with
1423 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1424 negcharset iso-8859-1,utf-8
1426 Translation of proximity nodes from CQL into PQF now works.
1428 Moved to automake 1.8, 1.9.
1430 Added function yaz_log_set_handler which allows a log handler to be
1431 installed. This handler will be called for all log messages. Output
1432 to file is also produced; but that can be disabled by passing NULL
1433 fname to yaz_log_init_file.
1435 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1437 For SRW (including GFS), accept application/soap+xml as content-type
1440 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1441 produces NO stylesheet reference even if a default stylesheet is specified
1444 --- 2.1.14 2006/03/14
1446 Updated Windows package to include yazd.dll + yazd.lib for the
1447 Development component.
1449 If the environment variable YAZ_LOG is set, then it is used as a
1450 string indicating the default level of logging to use if not
1451 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1452 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1453 used as before. So, for example, to omit warnings from YAZ logging,
1454 export YAZ_LOG=-warn
1456 cql_transform() now map structure and other attributes before indexes,
1457 so that index-specific structures and other attributes can override
1458 defaults. So now a combination of mapping specifications such as:
1460 index.dc.date = 1=date-modified 4=5
1461 does the right thing.
1463 cql_transform() now also respects the "always" mapping specification,
1464 which establishes an initial set of attributes to be used for all
1465 terms except where overridden by more specific attributes associated
1466 with the index, relation or modifier.
1468 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1469 which mode to use; one of "post", "get" or "soap" (SRW, default).
1471 Fixes for yaz_iconv routines: changed trie-based character set conversions
1472 to use only non-negative values for bit fields due to Sun's C compiler not
1473 supporting negative values.
1475 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1476 sequences where not read correctly. Fix by Rustam Usmanov.
1478 Updated win/makefile to use options, settings which makes things
1479 compile with VS C 2005.
1481 --- 2.1.12 2006/02/01
1483 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1485 In ZOOM socket code, use select instead of poll on MacOSX.
1487 ZOOM-C now support client-side compilation of CQL into RPN that is
1488 sent to the server, enabling CQL to be used against all Z39.50
1489 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1490 ZOOM_query object, and submit it using ZOOM_connection_search().
1491 The CQL-to-RPN translation uses a configuration file, the name of
1492 which must be specified in the Connection's "cqlfile" option.
1494 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1495 function, which takes as its start-term parameter a ZOOM_query object
1496 (which may have had either CQL or RPN set into it).
1499 --- 2.1.10 2005/11/29
1501 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1502 GFS to support this as well. Backend handler, bend_srw_update, does the
1503 update work. Code contributed by Ko van der Sloot.
1505 Allow retrieval of Search Result-1 information in ZOOM by the use of
1506 options that are attached to a result set. ZOOM documentation updated
1509 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1510 UTF-8 conversion. Patch by Raj Patel.
1512 Added option -m to GFS to control formatting of timestamps in log file.
1514 Added 'exit' as synonym for 'quit' in yaz-client
1516 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1517 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1518 for the new members. Patch by Ko van der Sloot.
1520 Added support for SRU POST. It is supported for content-type
1521 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1523 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1524 Instead make the library libyaz.la multi-threaded. Threading as a whole
1525 can still be disabled by configure option --disable-threads. Previosly,
1526 with older GLIBCs there were problems with MT libs under Apache. This
1527 has now been fixed a long time ago.
1529 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1532 CQL module modified to be case insensitive for relations/indexes/operations.
1534 Fixed bug in CQL transform code: incorrect value relationModifieder
1537 Added 'show all' command for yaz-client which retrieves all results
1540 Added new yaz-client, xmles, which takes a (private) OID and
1541 a document to be sent as an extended service request.
1543 Describe new yaz-client commands wait_response and set_auto_wait.
1545 Increase TCP/IP listener backlog from 3 (which I am guessing was
1546 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1547 that the socket will queue as many incoming connections as it's able
1548 to handle ongoing connections. In other words, it will never now
1549 refuse a connection that it would be able to handle merely because
1550 it's not got around to accepting() enough of the pending connections
1551 yet. This is the behaviour anyway under Linux, where the listen()
1552 argument is ignored; but not under BSD and on systems such as
1553 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1554 YAZ-based servers should now be uniform across operating systems in
1557 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1558 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1559 This allows yaz-marcdump to read large MARC batches (>2 GB).
1561 Modified all YAZ source files - except the source which is auto-generated
1562 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1565 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1566 corresponding to the existing *_setl() function. These allow option
1567 values containing arbitrary valuues.
1569 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1570 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1571 except that it returns an indicator of whether or not the sort
1572 criterion was accepted (0 for OK, -1 for invalid).
1574 --- 2.1.8 2005/06/07
1576 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1577 MARC output rather than returning "new" buffer.
1579 yaz-client warns about unknown init options.
1581 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1583 --- 2.1.6 2005/05/24
1585 Added support for SRW sort in Generic Frontend Server. Patch
1586 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1587 sortKeys - or NULL if none is provided.
1589 Fixed bug #307: It was impossible to specify indefinite/no timeout
1590 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1593 Added support for multiple languages and charsets to be specified in
1594 ZOOM. Each charset/language is separated by a blank. If negotiation is
1595 in effect in init-response, Option
1596 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1597 Code based on patch by Vasiliy Osadchuk.
1599 Fixed bug #306: infinite recursion that occurred when calling
1600 yaz_log_level_init as the first call (before other log level or
1603 Fixed bug in scan handling in front end server: if preferred-Position-In-
1604 Response was non-present, a NULL pointer referece was performed.
1606 --- 2.1.4 2005/04/26
1608 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1609 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1610 now defined for all those error codes. So instead of putting 109 in
1611 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1612 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1614 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1617 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1619 Program yaz-client now exits and produces an error message if multiple
1620 Z39.50 servers are specified on the command line (none or one allowed
1623 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1626 --- 2.1.2 2005/03/16
1628 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1630 Fixed bug #272: Preserve spacing for CCL terms.
1632 --- 2.1.0 2005/03/14
1634 Added support for virtual hosts and multiple backend servers for
1635 the YAZ frontend server. The configution is XML based and
1636 support specificition of CQL to RPN mappings and explain information.
1637 See section "Virtual Hosts" in the YAZ manual.
1639 Extended OPAC display utility. OPAC display utility renders
1640 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1641 to supplement yaz_marc_decode_wrbuf.
1643 Fixed a bug in MARC decoder that could caused it to crash for some
1644 invalid MARC records. More diagnostics and warnings where added in
1645 XML output (warnings, etc are stored in comments).
1647 --- 2.0.34 2005/02/08
1649 Fixes for UNIX domain sockets. Bug #261.
1651 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1653 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1654 Added yaz_marc_subfield_str which defines subfield lead string which is
1655 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1656 yaz_marc_endline_str which defines end of fields string used in
1657 YAZ_MARC_LINE format. Default string is newline.
1659 Experimental support for MarcXChange. This format can be produced
1660 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1661 http://www.bs.dk/standards/MarcXchange.xsd
1663 Added yaz-client commands scansize that sets maximum number of
1664 entries to be returned by scan.
1666 --- 2.0.32 2005/01/11
1668 Added support for SRW scan in yaz-client and Generic Frontend Server.
1670 * Added whereInList member to SRW Scan Term.
1672 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1674 Fixed NMEM system to return aligned blocks on the smallest boundaries
1675 that are suitably aligned for all possible types on the particular
1676 architecture YAZ is being built for.
1678 --- 2.0.30 2005/01/04
1680 Fixed numerious warnings that was issued with newer versions of GCC.
1682 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1683 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1686 Make YAZ Generic Frontend Server slightly faster.
1688 Enhance (and reduce) logging for Generic Frontend Server.
1690 Revert YAZ log system so that it flushes every write operation
1691 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1693 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1694 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1695 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1696 will effectively disable old definitions.
1698 --- 2.0.28 2004/11/09
1700 Added yaz_log_time_format which specifies log format using
1703 Added yaz_log_module_level which returns mask for a module. Value
1704 is non-zero mask a if module is enabled; zero if disabled.
1706 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1707 in include/yaz/cql.h.
1709 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1711 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1713 Fixed bug #172: RPM builds does not enable SSL.
1715 Doxyfile.in part of dist. Doxyfile generated by configure.
1717 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1718 are given and the corresponding component does not exist.
1720 Extend CCL documentation in YAZ reference. Describe r=r.
1722 --- 2.0.26 2004/10/01
1724 Fixed MARC->MARCXML conversion to properly deal with
1725 fields, subfields, indicators having non-ASCII characters.
1727 Fixed MARC->MARCXML conversion so that ASCII control characters
1728 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1731 Added YAZ GFS support for conversion from Z39.50 surrogate
1732 diagnostics to SRW surrogate diagnostics.
1734 Bug fix: YAZ GFS did not return schema in explainResponse.
1736 --- 2.0.25 2004/09/30
1738 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1739 now converts recordSchema to elementSetName as well as schema URI.
1741 Fixed bug in COMSTACK that prevented HTTP request packages from being
1744 --- 2.0.24 2004/09/29
1746 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1747 does not require white-space before and after the dash in a range, e.g.
1748 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1751 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1752 due to new GCC removing "redundant" code.
1754 Added yaz-client commands scanpos and scanstep that sets preferred
1755 position and step-size for scan.
1757 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1759 Added CCL utility ccl_qual_buf which parses one or more CCL
1760 spec lines in a buffer.
1762 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1763 of name and value - ignoring empty lines and comments.
1765 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1767 Added odr_get_element_path which returns current element path for an
1768 ODR handle. This utility is useful in error handling or user-defined
1771 Added ODR_PRINT utility odr_set_stream which is is a more generic
1772 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1773 to a write function and pointer to close function. The close function - if
1774 non-NULL - will be called during odr_destroy.
1776 Fixed bug in CCL parser where truncation char was not removed from
1777 right side when truncation=both was in effect.
1779 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1782 --- 2.0.23 2004/08/11
1784 Fix buffer overrun in CQL parser when dealing with proximity (%).
1786 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1787 to UTF-8/UCS conversion is now only based on codetables.xml.
1789 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1791 --- 2.0.22 2004/08/06
1793 Add support for more "commit changes" in ZOOM (uses Extended Services).
1795 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1798 Yet another small fix for configure of SSL.
1800 --- 2.0.21 2004/05/14
1802 Fix SSL libs for configure when --with-openssl=DIR is given.
1804 --- 2.0.20 2004/05/10
1806 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1808 SSL comstack now uses yaz.pem certificate file on server side
1809 by default. Certificate filename can be configured by calling
1810 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1812 Fix bug regarding multiple calls to ZOOM_connection_connect.
1814 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1816 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1817 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1819 ZOOM now allows inspection of X509 peer certificate for verification.
1820 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1822 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1823 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1824 as "modular" but it simplifies things.
1826 Added cs_get_peer_certificate to that returns peer X509 PEM.
1828 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1829 NULL if SSL is unavailable.
1831 Documentation about MARC decoding tools.
1833 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1835 --- 2.0.19 2004/03/30
1837 Rename CHANGELOG to NEWS to follow GNU style packing.
1839 Fix bug with missing initialization of member in init_diagnostics.
1840 This bug affects threaded version of GFS server.
1842 --- 2.0.18 2004/03/20
1844 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1847 Ensure zlib.dll is packed with Windows install.
1849 --- 2.0.17 2004/03/17
1851 Fix encoding of xsd:string to use text instead of CDATA.
1853 Fix endless loop in CQL parser with unbalanced ".
1855 Use a more compact way to store MARC-8 conversion tables.
1857 --- 2.0.16 2004/03/16 Debian only
1859 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1862 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1867 --- 2.0.15 2004/03/01
1869 Another fix for decoding of XML packed records.
1871 --- 2.0.14 2004/02/25
1873 Fixes for Chunked encoding. White space not ignored after length spec.
1875 Update NS and use default NS for SRW diagnostic elements.
1877 --- 2.0.13 2004/02/23
1879 Implement ZOOM_resultset_cache_reset which resets record cache.
1881 Implement ZOOM_resultset_sort which sorts a result set.
1883 Implement chunked HTTP transfer.
1885 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1887 --- 2.0.12 2004/02/16
1889 Added member 'schema' to bend_explain_rr structure so that backend
1890 can specify explain record identifier. Defaults to Zeerex 2.0.
1892 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1894 --- 2.0.11 2004/02/16
1896 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1899 Added init command for yaz-client which sends "extra" init request.
1901 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1902 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1904 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1906 Make ZOOM error code for "invalid query".
1908 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1910 --- 2.0.10 2004/02/05
1912 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1915 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1917 Added option -p <file> to make Generic Frontend Server to write PID file.
1919 Added option -D to put Generic Frontend Server in background on its own.
1921 Make ZOOM C recognize option "password". If unset, "pass" is used
1922 (for backwards compatibility).
1924 Fixed a bug in Generic Frontend Server that could make it crash if a
1925 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1928 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1929 Must be issued before open, in order to be in effect.
1931 --- 2.0.9-6 2004/01/12 Debian/Windows
1933 Make the SRU server more picky WRT unknown params, etc.
1935 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1937 New YAZ client command, options, that sets Z39.50 options.
1939 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1940 options from a string of tokens (one token for each option bit).
1942 Update SRW diagnostic code messages.
1944 --- 2.0.9-5 2004/01/07 Debian/Windows
1946 Handle user defined stylesheet for SRW/SRU.
1948 --- 2.0.9-4 2004/01/06 Debian/Windows
1950 Fix bug in decoding of Content-Length.
1952 --- 2.0.9-3 2004/01/06 Debian/Windows
1954 Fix a bug with decoding of XML packed records.
1956 --- 2.0.9-2 2004/01/05 Debian only
1958 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1960 Fix bug in SRW/SRU diagnostics decoding.
1962 --- 2.0.9 2004/01/05
1964 Fixed bug in Generic Frontend Server which could drop records exceeding
1965 preferred message size. Reported and fixed by Irina Dijour.
1967 Fixed calculation of package size for structured records in Generic
1968 Frontend Server. Reported and fixed by Irina Dijour.
1970 Fixed namespace for SRW/SRU diagnostics.
1972 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1974 --- 2.0.8 2003/12/22
1976 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1977 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1980 CQL changes to reflect recent changes to the specification:
1981 * Documentation talks about context sets instead of index sets.
1982 * Documentation talks about indexes instead of qualifiers.
1983 * The CQL-to-PQF transformer's configuration file now uses
1984 "index.set.name = <attributes>" instead of the old form
1985 "qualifier.set.name = <attributes>". (Both forms are still
1986 understood but the latter is deprecated.)
1987 * CQL terms with no explicit index specified are now interpreted as
1988 cql.serverChoice instead of srw.serverChoice (which of course
1989 behaves exactly the same.)
1991 --- 2.0.7 2003/12/16
1993 MARC conversion can now generate ISO2709 output in another
1994 character set. yaz-marcdump uses this facility if you invoke it
1997 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1998 functions from there can be used from C++.
2000 --- 2.0.6 2003/12/04
2002 Frontend server now transfers memory from decoded packages to stream
2005 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2006 references to show up.
2008 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2009 the ZOOM Abstract API. The older names for the same options are still
2010 also supported for the benefit of old applications.
2012 ZOOM-C supports "implementationId" and "implementationVersion" options
2013 to go along with "implementationName". These allow the user code to
2014 specify identification strings to be sent to servers.
2015 Add OID for the new ExtLite attribute set.
2017 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2018 as requested/supplid by Ere Maijala <ere@atp.fi>
2020 For generic frontend server, reverse the order of
2021 "toolkit-supplied / application-supplied" strings sent as implementationId,
2022 Name and Version. Also, remove the spaces around the slash. This brings
2023 the GFS in line with the behaviour of ZOOM-C on the client side.
2025 Add function ZOOM_scanset_display_term.
2027 yaz-client shows scan displayTerm if present.
2029 Utility yaz-iconv is now installed by default along with the man page
2032 Extend configure check for OpenSSL to use pkg-config where available (such
2035 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2036 server to specify uid/gid/mask for socket using the format
2037 unix:[user=uid,][group=gid,][umask=mask,]file=path
2038 If file= is omitted the existing format is assumed, e.g.
2040 in which case the mask is 0666 (rw for everybody).
2042 Major restructure of YAZ source. All source in libyaz is in src directory.
2043 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2044 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2046 Added man page for utility yaz-marcdump (used to be called marcdump).
2047 yaz-marcdump is installed by 'make install'.
2049 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2050 of incoming package failed.
2052 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2054 Change prototype of odr_perror: add const to message string.
2056 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2058 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2059 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2060 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2061 DNS lookup. There should not be any compatibility problems with this
2062 assuming that blocking=1 or 0 is used.
2064 Fix bad reference in UNIX comstack in function cs_addrstr.
2066 Fix for compilation on AIX.
2068 The generic front-end server (server/seshigh.c) now supports returning
2069 Init diagnostics to the client in User-information-field, in
2070 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2073 --- 2.0.4 2003/09/04
2075 Allow any CQL relation (not just all,any,exact,scr).
2077 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2078 that features the same UI.
2080 Implemented command update0 in YAZ client which is equivalent to
2081 update but uses old of Ext Update ASN.1.
2083 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2084 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2085 Previously no OID was used for this info.
2087 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2088 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2089 returns 'malformed search term' otherwise.
2091 SortResponse member resultCount now set to NULL in sort handler of
2094 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2097 Add three new utility functions for translating OIDs between various
2098 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2099 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2100 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2101 char *oid_to_dotstring(const int *oid, char *oidbuf);
2102 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2104 Reverted modifications for ES Update definition for z_IU0Update
2105 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2106 is back to YAZ 2.0.2.
2108 String value attributes for CCL parser.
2110 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2111 which their FirstSearch server returns in Init responses, sometimes
2112 carrying useful diagnostic information when Init fails. This has the
2113 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2114 "z39.50/oclcui.asn", where its definition is somewhat different from
2115 what OCLC document on their web-site, as required to interoperate with
2118 Support for anonymous authentication in yaz-client. Use the command
2121 * Fix the OID of the Index Data-local "admin" Extended Service from
2122 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2123 the 1000, which indicates a locally-defined OID, was a mistake.
2125 --- 2.0.3 2003/06/20
2127 Fix CCL directive @case handling so that it affects string match for
2128 both CCL keywords and qualifiers.
2130 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2131 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2132 Decoder has been updated with ASN.1 changes as listed in
2133 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2134 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2135 z_IUUpdate, remains unchanged.
2137 ZOOM_record_get may now return a record in a specific character set.
2138 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2139 "from" is the character set of record as returned by target. "to" is
2140 the character set to be returned. If omitted, "to" is UTF-8.
2142 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2144 New ODR utility, odr_getelement, which returns name of element for
2145 which encoding/decoding failed.
2147 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2148 in cases where a required element was omitted.
2150 Bug fix: some MARC8 sequences were not converted.
2152 New ZOOM option "step" which specifies number of records to be
2153 retrieved in one chunk. Used in conjunction with "start" and "count".
2155 SRW support for yaz-client. Use scheme http: to use it, e.g.
2158 yaz-client no longer does (un)intelligent character set conversions
2159 by default. Can be enabled with charset and marc_charset commands.
2161 xmalloc trace fix for 64-bit systems such as DEC alpha.
2163 Solaris 2.6 compile fix.
2165 New function, cql_strerror() translates SRW error codes, as returned
2166 by cql_transform_error(), into human-readable English strings. Used
2167 in yaz-client diagnostics when appropriate.
2169 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2170 converts it into a type-1 query which is sent to the server. This
2171 makes CQL available for use with all Z-servers, as opposed to the tiny
2172 minority that can handle CQL queries themselves.
2174 --- 2.0.2 2003/04/28
2176 New Debian package layout similar to the Redhat Package layout.
2178 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2179 and search result respectively.
2181 --- 2.0.1 2003/04/25
2183 Redhat package is now several packages: libyaz (runtime libraries),
2184 libyaz-devel (development and documentation, and yaz (utility programs).
2185 Package spec file by Morten Bogeskov.
2187 New member 'schema' in struct bend_fetch_rr which the name of requested
2188 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2189 handler MAY set this to reflect the schema of the returned record.
2191 New member 'display_term' in struct scan_entry. GFS now sets member entries
2192 and allocates scan entries to be filled by user scan handler. In previous
2193 version, entries member was allocated by the scan handler. That still works,
2194 but the GFS will ignore member display_term - assuming it was NOT set by
2195 the handler. The fact that the GFS now allocates the entries both allows
2196 for new members and makes a scan handler easier to write.
2198 Fix CQL lex buffer overflow.
2200 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2201 SRU default recordPacking is string.
2203 SRU protocol support for frontend server.
2205 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2207 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2209 Added scan for the ZOOM shell (zoomsh).
2213 * String Identifers for Schemas (Amendment 5).
2214 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2215 Old definition for schema
2216 Odr_oid *schema; /* OPT */
2221 Z_InternationalString *uri;
2222 #define Z_Schema_oid 1
2223 #define Z_Schema_uri 2
2226 * resultCount parameter to Sort Response (Amendment 1).
2227 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2229 Support for SRW 1.0 over HTTP. This is an optional feature and
2230 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2233 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2234 on the same port. SRW SearchRetrieveRequests are mapped
2235 to bend_init,bend_search,bend_fetch,bend_close.
2237 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2239 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2240 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2242 ZOOM connections are SRW based if schem http is used for hostname
2243 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2244 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2246 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2247 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2248 distance=n, order=true/false, relation=le, prox unit=word. If
2249 n is omitted, distance 1 is used.
2251 Fixed problem with C compiler include path in wrong order.
2253 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2254 on Solaris. Patch from Ko van der Sloot.
2256 New MARC decode API. All new functions operate on a yaz_marc_t
2257 handle. The most important new functions are: yaz_marc_create,
2258 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2259 decode and destroy respectively. Decoder can produce formats
2260 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2261 include/yaz/marcdisp.h.
2263 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2264 to UTF-8, UCS-32, wchar_t or Latin-1.
2266 * Prototypes for yaz_iconv_-functions moved to separate header
2267 include/yaz/yaz-iconv.h.
2269 Make a few private functions 'static' in unix.c. This prevents
2270 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2272 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2273 are set when Init Response is received.
2275 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2276 but returns diagnostic set as well.
2278 New function yaz_strerror which is a portable wrapper for
2279 strerror/strerror_r/GetLastMessage.
2281 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2282 is returned for MARC. If type is "oai", then OAI MARC is returned.
2284 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2287 --- 1.9.2 2002/11/26
2289 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2291 Fix bad race conditions on SIGTERM and terminate gracefully in
2294 Move retrieval (data1) module to Zebra since nobody seems to be
2297 Add GRS-1 render for ZOOM using same format as yaz-client.
2299 --- 1.9.1 2002/10/05
2301 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2303 Fix broken ESpec handling in data1 module.
2305 SGML reader parses comments and makes them part of the data1 tree.
2307 Added several type casts so that YAZ compiles as C++ code.
2309 ZOOM didn't handle PDU encoding failures properly.
2311 Added more Bib-1 diagnostics (approved extensions).
2313 GNU configure: better check for iconv.
2315 More portable use of accept, getpeername. Check for socklen_t. Use
2316 int/size_t if socklen_t is not defined.
2320 PQF parser rejects bad queries - including those with extra
2321 characters in them. PQF parser used to silently ignore that.
2322 Cleaner API for PQF added, which allows you to get detailed
2323 error information for bad queries (see yaz/pquery.h).
2325 Fixed bug in ZOOM_record_get for type "database".
2327 Implemented mini iconv library supporting conversions between
2328 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2330 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2332 --- 1.8.9 2002/08/20
2334 Fixed ZOOM C record cache so that preferredRecordSyntax and
2335 elementSetName is used to check for already fetched records.
2337 --- 1.8.8 2002/08/02
2339 Added three members in bend_initrequest structure to facilitate
2340 character set negotiation.
2342 Fixed a bug in frontend server that could cause indefinite
2343 loops under rare conditions.
2345 Revised character set utilities (charneg.h) so that encoding
2346 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2348 For PQF, directive @term <type> sets term type for Scan/Search.
2349 Here <type> is general, string, numeric, null. The term type
2350 is inherited - just like @attr.
2352 New call odr_set_charset that sets character set conversion for
2353 international-strings on a ODR stream. Prototype is:
2354 int odr_set_charset(ODR o, const char *to, const char *from);
2355 The InternationalString is still represented as C string in YAZ
2356 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2357 won't). On the protocol level, you can use any encoding.
2359 Support for UNIX sockets in ZOOM.
2361 Solaris recv sometimes returns errno == ENOENT. It is treated as
2362 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2364 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2365 both client and server. Code by Morten Bogeskov.
2367 --- 1.8.7 2002/05/22
2369 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2370 that they can be used directly from Visual Basic. You must recompile
2371 your windows APP if you're using ZOOM.
2373 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2374 Commands "lang" and "charset" sets language and character set respectively.
2375 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2376 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2378 Attributes from multiple CCL fields may be OR'ed rather than merged
2379 using directive "@field or". Fields are still merged by default -
2380 equivalent to "@field merge".
2382 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2385 Fixed bug in zget for parameter ExtendedServicesResponse.
2389 --- 1.8.6 2002/03/25
2391 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2393 Client displays USR.1:SearchResult-1 (hits per term).
2395 Additional Search Info for search in Generic Frontend Server.
2397 Fixed CCL parsing of "field=s".
2399 WIN32 installer - using the excellent NSIS software from nullsoft.
2401 Fixed CCL parsing of "field = - <number>".
2403 Added function yaz_marc_decode that decodes MARC for line mode
2404 display or XML (similar to that used by JZKit).
2406 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2407 Z39.50. But ISO/ILL was, however.
2409 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2410 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2412 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2413 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2415 --- 1.8.5 2002/02/03
2417 New YAZ client features: Command completion and new commands:
2418 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2419 Code provided by Jacob Poulsen.
2421 New call oid_trav, that visits all registered OIDs via callback.
2423 Function ZOOM_record_get now returns const char pointer rather than
2424 void pointer. It saves a lot of type casts.
2426 For YAZ client, command "auth" now allows you to set authentication
2427 in IdPass style. It is enabled when three tokens are given - order
2428 is user, group and password.
2430 Fix memory leaks in MARC record handling for ZOOM.
2432 New option for YAZ client, -k <kilobytes> that sets
2433 maximum record size. Similar to -k option for generic frontend
2434 server and yaz-ztest.
2436 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2438 Prefix query parser reports "fail" when bad attribute set is given.
2440 Fix in MARC decoder. Proximity logging. Fix for attribute set
2441 in scan handler for server. Patches by Shigeru Ishida.
2443 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2446 Configure option --with-openssl=<dir> now works when a directory is
2447 specified. Patch provided by Morten Bogeskov.
2449 New option for YAZ client, -u <auth>, that sets authentication.
2451 ZOOM fix: error information was sometimes "missing", since error
2452 was cleared/reset too when it shouldn't.
2454 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2456 --- 1.8.4 2002/01/04
2458 Scan for ZOOM API. New object ZOOM_scanset. New functions
2459 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2460 ZOOM_scanset_destroy.
2462 New ZOOM function, ZOOM_connection_last_event, that returns type
2463 of last event (such as "receive data", "send data", "apdu received",
2466 New ZOOM option, schema, that specifies schema for retrieval.
2468 New CCL feature. Qualifiers can be aliases for one or more
2469 other qualifiers (if more than one is given, OR is used).
2471 ZOOM uses named result sets if target supports it.
2473 Two new YAZ client commands: . (dot, which sources a script of YAZ
2474 client commands), and ! (to execute shell command.). Implemented
2477 Working on Debian packages.
2479 --- 1.8.3 2001/11/19
2481 YAZ client enables named result sets only if target supports it.
2483 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2485 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2486 with key="host" to get same result.
2488 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2489 Function Z3950_resultset_record(s) returns references to records
2490 "owned" by resultset. To become owner use Z3950_record_clone.
2492 Function z_ext_record handles Extended Services. Thanks to
2495 --- 1.8.2 2001/11/12
2497 CCL Parser fix: ignore token comma when dealing with and-lists.
2499 Documentation updates for COMSTACK.
2501 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2502 Changed prototype Z3950_records. For some functions, int parameters
2503 were changed to size_t.
2505 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2508 New MARC decode/display function, marc_display_exl, which properly rejects
2509 non-ISO2709 records. YAZ client uses it.
2511 --- 1.8.1 2001/10/29
2513 Fix bug: local attribute set wasn't set correctly in PQF strings.
2517 * Old Z39.50 codecs no longer supported.
2519 Added ZOOM C binding. See http://zoom.z3950.org/
2521 Renamed states for COMSTACKs to avoid confusion with events.
2523 Implemented cs_look and proper cs_rcvconnect.
2525 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2527 Configure detects POSIX threads on OpenBSD.
2529 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2530 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2532 When error is returned from present handler, non-surrogate diagnostic
2533 is returned in present response (and fetch handler is no longer called).
2535 * Minor adjustments to pquery parser (PQF). Token characters may be
2536 escaped by using backslash (C-style).
2538 PQF parser allows string attribute values to be specified. For @attr,
2539 non-numeric characters after the equal-sign are treated as strings
2540 (e.g. @attr 9=title).
2542 CCL trunction character may be defined (@truncation in file)
2544 * function zget_ExtendedServicesRequest sets waitAction to
2545 waitIfPossible (was wait).
2547 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2550 CCL operator names may be set in field definition files (CCL_bibset).
2551 See ccl/bib1 for an example.
2553 Fixes in ASN.1 compiler for C++ compatibility.
2555 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2556 and "op_or" to avoid conflict with C++.
2558 Fixed problem with GNU readline detection on Redhat 7.0.
2560 Added step-size for Scan backend handler.
2562 Fixed bug that made the frontend server crash when no attribute
2563 set was specified for scan.
2565 Front-end server automatically switches to original working directory
2566 when installed as an NT service. Previously -w had to be specified to
2569 Added extended attributes for retrieval module (data1), so that data1
2570 records carry d1_readXML/SGML attributes. d1_read also supports
2571 null-data rules ( <tag/>)
2573 On UNIX when POSIX threads are available, a separate library libyazthread
2574 is created. Programmers should link with that library and the yaz library
2575 when using threads. The reason for the split was that some applications
2576 on Linux, such as Apache, doesn't work well when using shared objects that
2579 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2580 (or any frontend server) in SSL mode by specifying ssl: followed by
2581 address. Only tested on UNIX.
2583 Added feature for CCL module. Virtual structure s=al or s=ol generates
2584 and-list and or-list respectively instead of phrase search.
2588 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2589 log_mask_str. This was done to avoid name conflicts with other libraries
2590 (such as other PHP extensions).
2592 Added raw OID member for preferred record syntax (request_format_raw)
2593 and returned record syntax (output_format_raw) for backend fetch method.
2595 Config file yaz-config now accepts options so that it returns specific
2596 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2598 Shared library support for UNIX using GNU libtool.
2600 * Modified backend interface. Request/Response struct's replaced by
2601 one read/write C struct. For example bend_fetchrequest and
2602 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2603 Every handler - even search has to be registered in bend_init
2604 handler. This means that the YAZ library no longer refers to
2605 external functions and it makes it possible to make the whole
2606 thing a single DLL/SO.
2608 Added Segment handler for backend server.
2610 Added Zmbol/Zebra administrative functions to YAZ client.
2612 Threaded frontend server on UNIX (when POSIX Threads are available).
2613 Starting the server with option -T enables multi-threading.
2617 Added configure option --enable-comp/disable-comp to control use
2618 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2619 located in sub directory asn.
2621 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2622 in ${exec_prefix}/bin along with the other programs yaz-client and
2625 GNU automake used to maintain makefiles.
2627 Added several OID's.
2629 Changed retrieval module so that we can load records with no abstract
2630 syntax defined. Tagpaths in these records are fully composed of string
2633 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2637 On UNIX, the generated makefile now supports a proper 'make install'.
2638 The prefix can be set via GNU configure to set the install location
2639 (default is /usr/local).
2641 * YAZ programs client and ztest were renamed to yaz-client and
2642 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2643 locations, such as /usr/bin,/usr/local/bin,etc.
2645 * YAZ Header files were moved from include to include/yaz. YAZ Header
2646 files are referred to as include <yaz/log.h> rather than <log.h>.
2647 The YAZ include path (-I ..) is therefore the same as before. Programmers
2648 should update their #include statements or use -Ipath/include/yaz
2649 instead. The main motivation for doing this change is that YAZ header files
2650 can be installed in "standard" locations /usr/include,/usr/local/include
2651 without introducing conflicts, since ALL YAZ header files are stored
2652 in subdirectory yaz (under /usr/include for example).
2654 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2655 rather than project/workspace files. We switched because project files
2656 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2659 Changed name of logging function, logf, to yaz_log, to prevent name
2660 clash with some math-log functions. The YAZ header log.h defines logf
2661 to yaz_log (#define) so there should be no incompatibilities by this
2664 Added bend_start/bend_stop handlers for server. These handler are
2665 called on start/stop of server. For windows they are called whenever
2666 a service is started/stopped.
2668 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2669 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2670 in util/yc.tcl. The auto-generated C code structures are, in a few
2671 cases, incompatible with the old decoders. There are differences in the
2672 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2673 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2674 The preprocessor variable ASN_COMPILED is defined when the compiled
2675 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2676 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2677 wish to use the old encoders/decoders you can specify --disable-yc
2680 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2681 version so that it supports both new - and old version of DB Update
2683 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2684 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2685 change. The name parameter can be set to 0 in which no name is specified
2686 for the construction. The macros odr_implicit and odr_explicit sets name
2687 parameter to zero for the construction involved. New macros
2688 odr_implicit_tag and odr_explicit_tag are similar to the others,
2689 except that a name parameter is added. For programmers' that don't use
2690 ODR they probably only need to change the call to z_APDU and z_External.
2692 Added access control facility by interfacing the TCP wrapper library.
2693 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2694 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2695 name of the daemon and enables the access control as specified in
2696 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2698 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2699 den Dool <H.M.vdnDool@kub.nl>.
2701 Added reference ID parameter to most functions in server API - refer
2702 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2704 Changed name of ccl library to libccl.a (was ccl.a).
2706 Fixed bug in decoder for Explain (Category TargetInfo).
2708 Added support for GNU readline in client. Thanks to Jacob Poulsen
2709 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2711 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2712 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2713 IMPLEMENTATION! This change was made to the development version before
2714 the ZIG decided to retract the amendment. If any users MUST be
2715 compatible with the original Update definition, PLEASE CONTACT US, and
2716 we will include a separate definition corresponding to the old Update
2717 ES. Note that because of the change to the ASN.1 of the
2718 TaskPackageRecordStructure we cannot define a single structure that
2719 will support both versions.
2721 * Added const modifier to buffer parameter for some ODR/BER encoding
2722 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2723 completeWAIS, odr_dumpBER.
2725 Fixed bug in client.c which caused a crash when a scanResponse didn't
2726 contain positionOfTerm.
2728 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2729 * will cause an error in a client if a non-YAZ target sends both a
2730 * list of Scan entries and non-surrogate diagnostics.
2732 Retrieval module enhancements. Tag sets may be typed in the reference
2733 to it. From the .abs-file the "tagset" directive takes a third optional
2734 integer type for the tag set referenced. From a .tag-file the "include"
2735 directive takes a third optional type as well. The old "type" directive
2736 in the tag set itself is still recognized but acts as the default type
2739 Backend interface change. Individual Scan terms returned from bend_scan
2740 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2741 in include/backend.h.
2743 Retrieval module enhancements. Multiple tag sets and attribute sets may
2744 be specified in abstract syntax specs. Revised the error/warning for
2745 logging messages reported by the retrieval module when reading the
2748 Object Identifier system (oid_..) changed. The API is backwards
2749 compatible but the oid-routines now allocates new OID's when needed.
2750 Raw OID's may be specified in oid_getvalbyname.
2752 YAZ now uses GNU configure to generate Makefile(s).
2754 * Minor changes in some of the member names of DeleteResultSetRequest and
2755 DeleteResultSetResponse. See include/proto.h.
2757 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2758 and added member 'languages' in TargetInfo (which was missing).
2760 Changed the way attribute sets are handled in the retrieval
2761 module. These are now cached, just like the abstract syntaxes
2764 Changed YAZ so that it links with compiled ASN.1.
2766 Added Explain-schema definitions and mapping routines. The following
2767 Explain categories have been implemented: AttributeDetails,
2768 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2770 Fixed minor bug in Windows version of Server Library.
2772 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2774 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2776 Added EXTERNAL: UNIverse Resource Report (non-standard).
2778 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2779 ENUMERATED and SET OF.
2781 * Added 'const' to some of the char pointer arguments for the
2782 functions, data1_read_node, data1_getelementbytagname,
2783 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2786 Fixed bug in data1_insert_taggeddata - the last_child member of
2787 parent wasn't initialised.
2789 * Changed data1_read_record and data1_read_node so that the supplied
2790 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2791 doesn't refer to any parts of the "SGML"-buffer.
2793 Fixed bug in server library (Windows version of statserv_remove).
2795 * Changed code so that it compiles as C++. The type definition
2796 of Odr_fun which is a member of Odr_arm was changed. The result is,
2797 that an explicit typecast is needed for the fun pointer when
2798 using Odr_arm - as in:
2799 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2801 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2803 Implemented the new structured date and time definition as approved
2804 by the ZIG. Added schemaId element to the specificTag in Espec-1
2805 (also approved at the last ZIG). Thanks to RVDM.
2807 Added some Object identifiers (RVDM).
2809 Changed the Update Extended Service (RVDM).
2811 Added command "refid" to client which specifies referenceId for
2812 the following requests.
2814 Implemented extended service handling for server. See ztest.c
2815 for an example as well as backend.h. New handlers are registerd
2816 in the Init handler.
2818 * Changed interface for sort in server.
2820 Added new members to statserv_options_block. It allows a server
2821 to read options from another source than just the command line. Thanks
2822 to Charles Woodfield.
2824 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2825 renamed to zboolean. Some C++ compilers complained about the name.
2827 Minor changes to gils.abs. Added index 's' (sort) on title
2828 and date/time-last-modified.
2830 --- 1.4pl2 1998/1/30
2832 Fixed bug in server library regarding inetd mode (-i). This bug
2833 was introduced by release 1.4.
2835 --- 1.4pl1 1998/1/29
2837 Added sort facility in client and backend server interface.
2839 Fixed problem with dependencies in Makefile(s).
2841 Fixed bugs for encoders/decoders of extended services and
2844 Implemented sub-tree feature for schemas. Sub-trees are
2845 referenced in *.abs-files. See explain.abs for an example
2846 of the use of this feature.
2848 Modified bib1.att; local attributes for ANY didn't include
2849 ANY itself (only affects use of the retrieval module).
2851 Fixed bug in plain SGML reader in function data1_read_node:
2852 tags with prefix "var" was incorrectly interpreted as variants.
2854 Added feature "sub-schemas" to enable references to - and definitions
2855 of - group of elements.
2857 * Removed member parent from type data1_element (in data1.h).
2859 Implemented function odr_nullval() that returns the value of
2862 * Removed member num_children from data1_node (in data1.h).
2864 Made NT service interface part of the server library. The
2865 function statserv_main uses the NT service when required and
2866 calls the statserv_start / statserv_close routines.
2868 Routine zget_SearchRequest and zget_PresentRequest fills
2869 resultSetName/Id member with "default" instead of "Default".
2871 Fixed memory leak in server. Request queue member wasn't freed.
2873 Fixed nmem_exit so that memory is freed.
2877 Revised the CCL parser utility to be thread safe.
2879 Added function, oid_ent_to_oid, to replace the function
2880 oid_getoidbyent, which is not thread safe.
2882 * Added nmem_init and nmem_exit to initialize and release
2883 NMEM resources. Function nmem_init should be called once in the
2884 initial thread before NMEM/ODR is used. statserv.c and client.c
2885 have been changed accordingly. The change was necessary to make
2886 NMEM thread safe. The NMEM memory pool is shared amongst threads
2887 in a process. Unix-based applications will still work fine without
2890 Added NT Services interface for the the Z39.50 (statserv) Server.
2891 Refer to the ztest.c source on the usage.
2893 Windows 95/NT port using MSVC5.0. Project files are included in the
2896 * Defined new 'global' handle for the retrieval (data1) system. The
2897 new handled, data1_handle, describes the state of the data1 system.
2898 This handle is passed as first argument to virtually all
2899 data1 related routines. The functions data1_create and data1_destroy
2900 creates and destroys a data1 handle respectively.
2902 Added ODR encode stream member to all backend request structures
2903 init, search, scan etc. This stream should be used to allocate all
2904 memory used for the response when thread safe operation is needed.
2906 Changed the comstack utility, cs_addstr, to be thread safe. The
2907 returned hostname string returned by the function is now part the
2910 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2911 function. The cs_straddr takes a COMSTACK handle as argument, so this
2912 function must be used after cs_create and before bind/connect.
2913 This function is thread safe.
2915 Moved test server to 'ztest' directory - generic server code still
2916 in 'server' directory.
2918 Made prefix query (pquery.c) utility thread safe.
2920 Added new function modifier YAZ_EXPORT to 'export' public DLL
2921 functions when using windows (see include/yconfig.h).
2923 Added definitions to the OID database (util/oid.c) (RVDM).
2925 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2927 Added call to ccl_rpn_delete in client program.
2929 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2930 release of RPN structure.
2932 Added support for C++, headers uses extern "C" for public definitions.
2933 With input from RVDM.
2935 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2936 Thanks to Ronald van der Meer (RVDM).
2938 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2940 Added support for private extensions to the OID database
2941 (oid_setprivateoids()). Thanks to RVDM.
2943 Added optional, physical ANY (key replication)
2945 Fixed null-reference problem in GRS-1 output filter.
2947 Proximity operator added to Prefix Query Format (PQF).
2949 In test client command "base" accepts multiple databases.
2951 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2955 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2957 Smallish bug-fixes in the new encoders/decoders (explain).
2959 Bug fixed in DeleteRequest.
2961 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2963 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2965 Added SOIF syntax (using private OID for now) to retrieval module and client.
2967 Added Update extended service.
2969 Added SearchResult-1 additional info structure.
2971 Added optional CCL (ISO8777) interpreter as separate module. Available
2974 --- 1.2 1996/6/10 (1st anniversary release)
2976 Added Summary record syntax. Lightly tested.
2978 Added OPAC record syntax. Untested.
2980 Added ResourceReport service encoders/decoders. Untested.
2982 Fixed bug in z_Unit - wrong tagging on unitSystem.
2984 Fixed bug in the DiagRecs decoder.
2986 Added options for max PDU size and session timeout to frontend-server.
2988 Added documentation of query-language parsers and other supporting utilities.
2990 [frontend-server] Added Attribute set to the bend_scanrequest API.
2992 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2993 surrogate diagnostics were generated.
2995 [retrieval] Allow multiple local values for attribute.
2997 [retrieval] Allow multiple attributes per element in .abs files. index type.
2999 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3001 --- 1.1pl2 1996/4/10
3003 Minor changes, mostly specific to Zebra's requirements (retrieval)
3007 Repaired bug in frontend server when running multiple listening
3008 endpoints in dynamic mode.
3010 z_External() now won't break if a known, ASN.1 value comes encapsulated
3011 in an octet-string. The value will pass through unmodified in an Odr_oct.
3013 Added a bit of code to the demo client to decode & display
3014 ASN.1-structured records represented in the octet-aligned branch of
3015 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3017 Added z_ext_getentbyref() to the ASN module. Doc updated.
3019 * Completed the SCAN definition in the ASN module. This may break SCAN
3020 code based on older YAZ-versions at compile-time. The fix is easy -
3023 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3024 under the SCAN definition. Remember to initialize this, server-people.
3026 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3027 that this does not extend to ODR and ASN.
3029 Comstack allows insertion of established socket (primarily for
3030 inetd-operation of servers). Doc updated.
3032 Front-end server can now start from the inetd in TCP mode. Doc
3035 --- 1.0pl4 1996/1/24
3039 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3040 the rank and record number.
3042 Adjustments to the frontend server.
3044 Fixed diagnostic BER dumper. It ignored the file argument.
3048 Various changes to retrieval module.
3050 Changed the union discriminators of the protocol files from enums to
3051 ints paired with #defines.
3053 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3056 *Changed operator in the RPN structure to 'roperator', again to avoid a
3059 Fixed problems in Explain decoders/encoders.
3061 --- 1.0pl2 1995/12/6
3063 Memory bug in log module fixed.
3065 --- 1.0pl1 1995/12/5
3067 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3069 Bug in Explain DatabaseInfo module fixed.
3071 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3075 The shift to v1.0 signals that we now consider the *core* functionality
3076 of YAZ reasonably stable (the core being more or less equivalent to
3077 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3078 tested (Explain not at all - though that will happen soonish).
3080 Minor changes to code to support Windows port.
3082 Various minor changes after we're getting to use GRS-1 & co. more.
3084 Added Espec-1 format.
3086 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3087 of the protocol and it cannot be selected when encoding (maps into 'string'
3088 when decoding). Needed to talk to some servers.
3090 Demo client can request simple element set names.
3092 Added Diagnostic Format encoders/decoders.
3094 Added simple Close handling to frontend server (no hooks for resource
3095 reporting yet), and demonstration client.
3097 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3099 --- 1.0b3 1995/08/24
3101 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3102 handled incorrectly when records were requested in the searchResponse. This
3103 will only affect you if you use the frontend-server.
3105 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3106 Test-client will ask for and print GRS1. Ztest will return dummy records
3109 Added Explain encoders/decoders to the service-level API. Untested.
3111 Added Extended Services: Item Order encoders and decoders to the Service-
3112 level API. Untested. We could use a recent copy of the pertinent bits
3113 of the ILL protocol to add those bits.
3115 Added diagnostic format 1 encoders/decoders to the service-level API.
3118 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3119 odr_cons.c, which causes a more correct output.
3121 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3122 was always set to 0 when no records were requested in the searchRequest.
3124 * Added better external-handling. This shouldn't harm old code that
3125 *encodes* externals. It can break code that looks for a
3126 'single-ASN1-type' representation, since those types that are known
3127 are now decoded immediately. Look at the SUTRS sample code in
3128 seshigh.c and client.c. Documentation updated.
3130 Handling of structured records in bend_fetchresponse. Length -1 marks
3131 structured record, type is deduced from format field.
3133 --- 1.0b2 1995/06/27
3134 Fairly quick maintenance release to add SUTRS support.
3136 Fixed handling of SUTRS records in the demonstration client.
3138 * Added format field to the bend_fetchrequest and bend_fetchresponce
3139 structures of the backend API (frontend server). When the record is
3140 returned, the value of the format field is mapped to an OID. The
3141 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3142 of the record. The special value VAL_NONE in the bend_request means
3143 that no specific format was requested by the client. Documentation
3144 updated accordingly. Test server (ztest) will return a fixed dummy
3145 SUTRS record if your client requests SUTRS.
3147 Documentation updated accordingly.
3149 You can now set external libraries and RANLIB support in the top-level
3153 First public release.
