2 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
3 sequence is treated as one. For example, &&a=b&&&c& is identical to
8 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
9 APDUs for a connection to a WRBUF.
13 Fix cql_sortby_to_sortkeys. Completely broken before.
15 Make CCL's @truncation work again.
19 New ZOOM connection setting: tproxy. It's like proxy, but does not
20 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
21 to set resolved address + port for a connection outside ZOOM itself.
23 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
27 Fix uninitialized variable in Solr spell support (could cause SEGV
28 for SRU response decoding).
30 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
31 back-end's addinfo through into the ZOOM response addinfo.
33 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
34 they are separated by a colon and a space rather than simply
39 Add support for Solr spell-checking/suggestions through ZOOM.
40 If a Solr target has been configured correctly for spelling-checking
41 and suggestions, these will now be returned on the ResultSet option
42 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
46 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
47 with a flag whether to substitute escape sequences or not.
51 Fix nmem_strsplit_escape to substitute escape char properly.
53 New option for zoomsh -e , which makes it abort on first error and
54 return process exit code to indicate success/failure.
56 YAZ options utility supports special option -- which makes all it treat
57 all following arguments as non-options.
61 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
62 searched if absolute filename is given.
64 Fix conv_xslt() error-reporting when stylesheet is not found.
65 (The value of fullpath is meaningless in this situation.)
69 Fix problem in CQL sort node creation: un-initialized memory.
71 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
72 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
73 CQL sortby depending on whether Type-1 or CQL is actually sent to the
76 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
77 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
79 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
80 will make it possible to use both single-character mask (#) and wildcard (?)
81 in CCL . Throw diagnostic for left truncation because that is not supported
86 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
87 cases using escapes (\-sequences) and masking.
89 PQF parse fix: A trailing backslash followed by end-of-string (\0)
90 would result in a read one byte beyond string.
92 rpn2ccl may use Z39.50 masking for terms (t=z).
94 ICU check fix. Don't include library -lCrun on Solaris, unless present.
96 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
97 not --cppflags (which seeems like an error in icu-config).
99 --- 4.2.12 2011/08/27 RPM package only
101 cql2ccl: fix conversion of terms: operator characters were not
104 --- 4.2.11 2011/08/25 RPM package only
106 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
107 CCL parser will map both # and ? to their regular expression
108 quivalents (. and .*).
110 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
111 of reserved CQL characters.
113 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
114 is, so that they are passed through.
116 --- 4.2.10 2011/08/24
118 ZOOM SRU mode: more aggressive re-connect.
120 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
121 made available as a utility function, declared in <yaz/logrpn.h>
123 rpn2cql_structure() supports proximity nodes (except that the Type-1
124 proximity node's "exclusion" binary is ignored, as there is no way to
125 express that in CQL). Fixes bug #4564.
129 Fix SEGV that could occur if set command of zoomsh was given without
130 value (2nd argument).
132 Fix SEGV that could occur if unsupported transport was given for
133 COMSTACK - say https (when SSL was unavailable).
135 Build yaz-url on Windows too.
139 New utility to get web content. Header is url.h. A command line tool
140 yaz-url is part of the distribution and packages.
142 Fixes for SSL COMSTACK (when gnutls is in use).
144 New functions yaz_base64{encode,decode}. Header is base64.h.
148 ZOOM C includes HTTP response buffer as additional info if it fails
149 to decode the SRU response.
151 Make wrbuf_json_puts available.
155 zoom: throw diagnostic for invalid value for option "sru". Before a
156 bad SRU request was sent.
158 Adding new utility wrbuf_vp_puts.
160 Add cclxmlconfig.obj to win/makefile. It was missing completely.
164 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
165 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
166 redirect was used at the same time.
168 MARC line mode decoding: be less picky about length given - first
169 5 digits of header that is.
171 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
173 Changes to decoding of SRU records: a record with recordPacking=xml is
174 modified with a new root element <yaz_record> if the recordData contains
175 multiple children elements. This is to make the record XML parseable
178 RPN to SOLR conversion: encode special characters.
180 Generic Frontend Server: fix uinitialized member, stepSize.
184 Fix a bug in SRU decoding of records.. The database records stored
185 had un-initialized memory, but it would only be seen with yaz_record_render
186 and type_spec="ext" .
188 Fix a bug in ccl_qual_dup introduced in 4.2.3.
192 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
196 Add new utilities to convert from CQL to CCL . These utilities have
197 prefix cql_to_ccl defined in cql.h.
199 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
200 lead to memory heap corruptions when ICU utilities were in use.
204 Make compilation work without Libxml2.
206 yaz-client: remove redundant blanks in display of searchResult-1 term
211 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
212 resulting CQL node (tree) in a new node CQL_NODE_SORT.
214 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
215 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
216 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
217 Note that the CQL sortby spec is only converted when the GFS is already
218 converting from CQL to RPN (cql2rpn element).
220 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
221 specify whether to collapse delimitors or not. The existing nmem_strsplit
222 do collapse (collapse parameter = 1).
224 Windows installer: For NSIS, set InstallDir depending on x86/x64.
226 Rename internal func yaz_use_attribute_create. While non-static, this
227 function is not declared in a public header.
231 Add -lCrun when linking with ICU on Solaris.
233 More quicks character set conversions for OPAC records.
237 fix problem with record_render: records were converted (character set
238 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
242 SRU: add methods for handling DADS SRU-proxy facets.
244 Separate OPAC record character set for ZOOM_record. yaz_record_render
245 allows a character set given as charset=from/opacfrom,to where 'from' is
246 the character set of a bibliographic record, 'opacfrom' is character set
247 of OPAC record and 'to' is the target character set.
251 yaz-client: show may XML format records. Command show followed by 'format'
252 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
255 src/stemmer.c: Avoid using unnamed union. It is not supported by some
258 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
261 Update yaz.spec to operate on both SLES11 / Centos 5.5.
263 RPM: Release includes 'indexdata' name. Use indexdata in release name so
264 this package can be distinguished from other vendors.
266 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
267 as determined by configure
269 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
271 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
272 returns no error and no record, the present request is considered
273 partial (only a subset of the records could be returned by backend), and
274 so it is appropriate to set Present Status to partial-4.
278 Move yaz-config man pages to section 1.
280 More documentation about SOLR.
282 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
283 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
284 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
285 peers on some Linux systems. However, in general that does not work
286 so YAZ can not rely on that to work. Debian changed behavior in this
287 respect from Debian lenny to Debian squeeze (still testing as of Oct
289 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
291 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
295 Fix yaz-config output: echo_source not set correctly by configure.
299 SOLR WebService support for yaz-client and ZOOM.
301 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
303 --- 4.0.12 2010/08/17
305 Z39.50 facet support. Facet specifications are passed for search in
306 other-information with ASN.1 as defined in facet.asn and OID
307 .10.1000.81.5 . Facets are expressed as an Attribute list as known
308 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
309 3 is limit (number of entries to get in response). yaz-ztest returns
310 dummy facets if a client asks for them.
312 --- 4.0.11 2010/07/09
314 CCL fixes: bug 2895 and bug 3539.
316 GR1-display: add comma in display - was removed by mistake in
319 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
321 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
323 --- 4.0.10 2010/06/18
325 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
326 result set from a connection. The result set will be on its own
327 thereafter; no operations on it will perform retrievals from a target.
328 Only cached copies are returned.
330 ZOOM C:fix case for HTTP servers responding with Connection:close.
331 Ensure that if there is a current task it is resumed (like fetching
332 more records in a result set) . Bug #3484.
334 PQF parser: use odr_atoi for Odr_int (not atoi)
336 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
337 values that contain any non-digits are treated as string attributes
338 (previously decoding only checked for leading character ([0-9]). PQF
339 encoding: attribute string values are not surrounded by double-quotes.
343 New utility for managing threads - thread_create.h.
345 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
346 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
347 but YAZ' implementation do.
349 Fixes for yaz_cond-functions on Windows 7.
351 DLL export more symbols.
353 zoomsh: show record do NOT render opac.
355 Remove *.la files from Debian and RPM packages.
359 Debian package libyaz-dev depends on libgnutls-dev again (was
360 removed in YAZ 4.0.6, but due to Libtool it is still needed
361 even though yaz-config do not list libgnutls libs).
363 ZOOM: Use only one WRBUF for returning string results for
364 ZOOM_resultset. Reduces memory usage for ZOOM in general.
366 ZOOM: ZOOM_connection do not use a shared pointer to
367 ZOOM_resultset after ZOOM_resultset is destructed by
368 user. Reverts to YAZ 4.0.4 behavior.
372 record-conv: fix problem with at least one XSL conversion -
373 due to probably incorrect usage of XML XSL documents.
377 Fix yaz-config for static mode and the use of SSL (gnutls).
381 Forward decl timeval struct in mutex.h and gettimeofday.h.
383 yaz-config: fix 'static' mode linking.
387 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
388 are wrappers for pthreads or Windows. For Windows these are put in
389 a separate DLL: yaz_cond4.
391 libyaz.la (whole source) is compiled with thread. If thread support
392 is enabled enabled, all source of YAZ is compiled with treading support.
393 This allows core utilities such as yaz_log to use thread facilities.
394 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
395 thread utilities. This commit moves mutex utilities (mutex.c) from
396 libyaz_server.la to libyaz.la.
398 yaz-json-parse displays leading text until error.
402 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
403 patch from Giannis Kosmas.
405 SRU: no longer URL encode SRU database. The URL for an SRU server is
406 a URL and such is alreeady encoded - at least when given with leading
407 http:// or https://. This reverts behavior to YAZ 3.0.50.
409 Support for new MARC XML notation TurboMARC which like MARCXML is a
410 complete representation of MARC/ISO2709.. This one, however, is more
411 compact and allows for faster processing with XSLT. TurboMARC can be
412 used in the marcdisp.h API, from the yaz-marcdump utility and from
415 yaz-ztest can be configured - via the database - to perform certain
416 delays when it performs operations search, present and single record
417 fetch. This allows testers to make yaz-ztest act as a real or even slow
418 Z39.50 server. Refer to the yaz-ztest man pages for details.
422 wrbuf_destroy allows NULL WRBUF passed to it.
424 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
426 Add ZOOM_connection_close.
428 No fixed size buffers for ZOOM shell - bug #3257.
430 tstodr: make it work on s390 platform.
432 New icu iterator-functions. The new icu_iter-functions makes it possible
433 to use ICU chains from many threads.
435 yaz-client: better syntax check for show command.
439 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
442 New simple local-file XML include facility which allows file glob-patterns.
443 Refer to yaz/xml_include.h.
445 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
448 ZOOM_record_get supports new parameter "format" which makes it format XML
451 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
452 JSONText in ECMA-262) is JSONValue, not JSONObject.
456 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
457 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
459 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
460 POSIX/Unix builds .so with major version 4.
462 Remove old LOG_-defines from log.h. They have been obsolete and
463 undefined by default for the last 5 years.
465 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
467 GFS: Remove socket (int *fd) from search_rr handler. The socket
468 descriptor ptr is a facility that allowed a search handler to supply
469 a socket which would serve as a callback - when search was complete.
470 This facility has now been in use for years.
472 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
473 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
474 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
475 returns 'const char *' rather than 'char *. The returned string is
476 read-only and should not be modified by applications. COMSTACK cs_close is
477 now a void function - it no longer returns int. No applications check for
478 the value and the implementations has always returned 0.
480 ZOOM: use size_t for scan hit counts and str size. Functions
481 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
482 occ (hit count) and len (string length) are now of type size_t pointer
483 rather than int pointer. This is to be able to represent large hit counts
484 and to also just to use the proper type for string length (strlen result).
486 New JSON parser. Refer to include/yaz/json.h .
488 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
489 Used to be int in some cases. Many wrbuf_-functions used to return an int
490 indicating some length.. These return values were never used. And so they
493 ODR: odr_malloc, odr_total now takes size_t for size.
495 clone_z_type: fix leak; occurred for encoding failures.
497 --- 3.0.52 2009/12/03
499 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
500 bug was introduced in 3.0.51.
502 --- 3.0.51 2009/12/02
504 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
506 tcpip comstack: fix leak for getaddrinfo.
508 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
509 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
510 Decoding of SRU "path" database is performed by private function
511 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
512 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
514 yaz-client: honor base command for SRU. Change when database setting
515 is applied for SRU and ensure it is kept when a connection is reset.
516 Change also the way errors are displayed or SRU (decoding of packages).
518 --- 3.0.50 2009/11/02
520 Add support for extra request / response data for SRU codecs and GFS.
521 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
522 for extra data response buffer and length. For the GFS, both request
523 and response data (XML) is carried in extra_args and extra_response_data
524 for the search handler. Patch by Ko van der Sloot.
526 ZOOM: For queries that cannot be converted to the specified rpnCharset,
527 ZOOM now returns a diagnostic on the client-side ('invalid query' /
528 10010). This fixes bug #2113.
530 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
531 cmdfile included a 'quit' command that would result in a memory violation.
533 --- 3.0.49 2009/10/01
535 Make a number of functions defined in xmlquery.c static. These have
536 never been declared in a public header file (yaz/xmlquery.h) and was
537 made public by mistake.
539 Improve speed of character conversions (iconv utilities). This makes
540 conversions from MARC-8 faster.
542 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
543 unless type desired is "raw". This will prevent type "xml" from
544 returning ISO2709 .. Which obviously can not be XML parsed.
546 Fix memory leak in ZOOM that would occur if option apdulog was used
547 on a re-used connection.
549 Frontend server logs HTTP requests.
551 Frontend server now sends Z39.50 close when it times out (sesssion has
552 been idle for too long). Versions 2.0.30 and earlier also sent close.
553 But due to a mistake this was disabled in all versions after that, i.e.
554 the server would just close the socket immediately.
556 yaz-client emits a better message when receiving an unrecognised
557 userInformationField.
559 Skip zero-length subfields when decoding ISO2709. This rare case happens
560 if a record has two FS characters in a sequence. Without this patch
561 there would be a reference beyond char array in using_code_len fragments
564 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
566 --- 3.0.48 2009/08/28
568 The show command offered by the zoomsh command now takes a 3d optional
569 parameter type which is what is passed to ZOOM_record. If the type
570 argument is omitted, "render" is used.
572 RPN to CQL conv may use USE string attributes (bug #2978).
574 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
576 --- 3.0.47 2009/07/08
578 Function yaz_xml2query allows a diagnostic element in the PQF XML
579 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
580 code and additional info respectively.
582 The BER BOOLEAN is now the integral type Odr_bool which still happens
583 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
584 typedef'd to Odr_int. This is still an integral 'int', but it may be
585 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
586 ASN-1 compiler as well as programs has been updated to use the new types.
588 --- 3.0.46 2009/06/08
590 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
591 only the bibliographic record was rendered. For type=opac, an OPAC
592 record is only returned if it is present.
594 iconv: small fix for encoding of advancegreek.
596 yaz-client: avoid double display of SRU/SRW records (bug #2798).
598 yaz-client: option auto_reconnect=on really reconnects.
600 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
602 server: avoid null ptr ref for for yaz_poll errors.
604 build: fix RPM build for RHEL 5.3.
606 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
608 --- 3.0.45 2009/03/31
610 Fixed bug #2709: TCP connect returns Invalid argument.
612 Fixed compilation for mingw.
614 Honor charset for raw records (ZOOM_record_get).
616 Fixed use of errno for threaded mode that was seen on Solaris 10.
618 Fixed argument passing with blanks in value for Windows Service.
620 Disable YAZ' own log rotate by default (no 1 GB limit).
621 The variable l_max_size which specifies the log file limit is set to 0
622 (DISABLED): This is due to the fact that YAZ is most often deployed using
623 logrotate. Also YAZ can not perform log rotate because of unsufficient
624 permissions (setuid).
626 --- 3.0.44 2009/02/17
628 List supported encodings in man page for yaz-iconv.
630 Fixed missing SSL libs for --libs output
632 Re-established OID record syntax application-xml. Nobody should use it
633 but we don't want to change soname because of this symbol being absent.
635 --- 3.0.42 2009/02/02
637 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
639 Added member named_result_sets for init handler struct for the GFS. This
640 allows a server to disable named result sets.
642 Removed OID record syntax application-xml.
644 Added support for rule-based transliterator for ICU wrapper of YAZ.
646 Fixed bug #1902: yaz-icu XML output.
648 Make YAZ checks Emacs friendly.
650 BITSTRING value shows value. Bug #2346.
652 ISO2709 decoding: skip control characters from indicator data.
654 Omit sort key by default in yaz-icu's output.
656 Allow combined single char options (again) for YAZ' options function.
658 Utility yaz-marcdump got option to display YAZ version (-V).
660 Allow YAZ to use ICU 3.4.
662 Added new ICU test case which illustrates removal of diacritics.
664 --- 3.0.41 2008/12/29
666 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
668 --- 3.0.40 2008/12/29
670 For configure, using option --without-xml2 also disables Libxslt/Libexslt
673 Fixed bug #2352: yaz-marcdump crashes for certain record.
675 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
677 Added support for Danmarc2 to UTF-8 conversion.
679 Added support for ISO5426 to UTF-8 conversion.
681 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
682 implementation version.
684 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
686 --- 3.0.38 2008/11/10
688 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
689 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
691 ZOOM C now interprets databaseName option for ZOOM connection as path
694 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
696 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
698 Dummy Libxml2 types no longer defined in headers of YAZ'.
700 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
703 --- 3.0.36 2008/09/26
705 Various ODR chapter fixes.
707 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
709 Added missing source for Windows compilation, mutex.c.
711 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
713 For SRU connections in ZOOM all records up to "count" are now fetched.
715 Fixed crash in generic frontend server (and yaz-ztest) which occurred
716 in Windows due to bad error handling for Libxml2.
718 Added facility for sending arbitrary records (ASN.1 any) using
719 ZOOM C's Extended service update. Patch by Sam Reynolds.
721 New options for ZOOM C's connection, logapdu which makes ZOOM log
724 --- 3.0.34 2008/06/18
726 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
728 --- 3.0.32 2008/06/12
730 Fixed memory violation that could occur when decoding UTF-8. This bug
731 was only present in 3.0.30 of YAZ.
733 --- 3.0.30 2008/06/06
735 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
736 GNU TLS is used by default (if found).
738 yaz-ztest returns OPAC records if a client asks for OPAC.
740 Improved speed of MARC-8 encoding.
742 Added support for lossy and loss-less MARC-8 encoding.
744 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
746 Added new Windows Service wrapper (sc).
748 yaz-client's itemorder command may now send a file.
750 Fixed yaz-marcdump to allow the use of NS prefix for record element.
752 Added new function yaz_log_xml_errors.
754 Allow (but warn) unknown XML attributes in MARCXML parsing.
756 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
758 The UTF-8 to MARC-8 conversion now uses a different set of characters
759 for Greek symbols. Bug #2120.
761 --- 3.0.26 2008/02/21
763 Added yaz_daemon (daemon.h).
765 Fixed bug #2068: pkg-config trouble
767 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
769 --- 3.0.24 2008/01/28
771 Document --with-xml2 option.
773 Added OPAC XML XSD (etc/opacxml.xsd).
775 Allow glob mask for name attribute in retrieval element for the
776 generic frontend server's retrieval facility.
778 Changed yaz_poll_poll to return yaz_poll_except for all returned events
779 except POLLIN/POLLOUT.
781 Fixed error handling in cs_listen. Bug #2037.
783 --- 3.0.22 2008/01/20
785 Fixed version in yaz/yaz-version.h.
787 Fixed bug #2027: Crash when closing connection.
789 Changed configure so that ICU support is only enabled if only ICU
790 and Libxml2 is available (because the ICU chain is XML based).
792 --- 3.0.20 2008/01/15
794 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
795 is built. Only this DLL depends on the ICU runtime.
797 yaz-ziffy is no longer part of YAZ. It is distributed separately by
798 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
800 Changed license of CCL module to 'Revised BSD'. After consultation with
801 remaining members of the original EUROPAGATE consortium, we are re-issuing
802 the CCL module without a separate license. The software was developed by
803 Index Data as part of a research project. The special license was included
804 to help feed usage information back to the project consortium to support
805 project evaluation. At this time, the project consortium has long-since
806 disbanded, and the majority of the original principals have retired. At the
807 same time, we have significantly modified the software during the following
808 years, to the point where very practically no original code remains. To
809 simplify re-use of the software, we have contacted those members of the
810 consortium who could be reached, and agreed to re-issue the module as a
811 proper part of the YAZ package.
813 Tcl scripts uses /usr/bin/tclsh as preferred shell.
815 CQL closer to being version 1.2 compliant. CQL also allows free-form
816 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
819 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
820 bug could make Extended services handling crash in the ZOOM layer. This
821 bug was only present in YAZ 3.0.18.
823 --- 3.0.18 2007/12/19
825 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
828 yaz-marcdump reads and writes collection wrapped records.
830 Handle OPAC for record conversion module.
832 Fixes for ICU wrapper.
834 Allow ICU libs to be controlled with --with-icu .
836 --- 3.0.16 2007/11/12
838 Added yaz_poll which is a wrapper for select/poll. When poll is available
839 and non-buggy, it is used, by yaz_poll . This allows more than 1024
840 sockets to be in use.
842 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
843 functionality through an XML based configuration (ICU chain). This system
844 is useful for search facilities such as Pazpar2 and Zebra that needs to
845 perform tokenization of indexed material. The ICU code in a separate
846 library libyaz3_icu.a.
848 Added HTTP tunnel facility for COMSTACK, bug #1752.
849 This is a facility that allows a Web proxy, such as squid, to tunnel
850 Z39.50 traffic. This facility is "transparent" to must applications
851 using YAZ. It's enabled by using pseudo transport connect: followed by
852 the proxy address, followed by command, then follwed by he regular
853 "virtual" addresss. For example,
854 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
856 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
858 --- 3.0.14 2007/09/21
860 Fixed bad memory reference in ZOOM_record - cuased by member not being
861 initialized. This was a problem only in YAZ 3.0.12.
863 Fixed bug in conversion from MARC to XML: Non-XML characters in control
864 fields were not removed.
866 Changed the way C code is generated from codetables.xml. Made a MARC-8
867 conversion trie for each characterSet section rather than codeTable.
868 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
869 of codetables.xml from Larry Dixson, LOC. Bug #1464.
871 --- 3.0.12 2007/09/12
873 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
874 from ZOOM_record_error).
876 ZOOM C function ZOOM_record_get returns record schema for type="schema".
878 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
880 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
882 Better SRW-to-Bib-1 diagnostic mapping.
884 ZOOM C and yaz-client announces SRU version 1.2 by default.
886 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
889 Fixed in yaz_sru_decode to allow other version than 1.1.
891 --- 3.0.10 2007/08/22
893 Added support for SRU scan for ZOOM.
895 Added support for the use of the older versions or Extended Service
896 Update in ZOOM. To faciliate this, an option "updateVersion" may be
897 set to the version , 1=first, 2=second, 3=third. The third version is
898 what ZOOM C has used so far. And that, obviously, is the default.
900 Added support for CCL queries in Z39.50 queries sent to the GFS (and
901 therefore in Zebra and in SimpleServer-based applications). The new
902 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
903 qualifier file used to transform incoming CCL queries into Type-1 RPN,
904 which is passed into the back-end search callback function.
906 Added support for HTTP Basic authentication in clients: the SRU/W
907 codec encodes the username/password elements of the PDU structure
908 appropriately, and these may be set using the "user" and "password"
909 options in ZOOM-C applications (the same options that are used for
910 Z39.50 authentication).
914 Fixed bug #1208: SSL appears to be broken in ZOOM.
916 Fixed bug #1206: Libxml2 include path weirdness.
918 Added oid_name_to_dotstring.
920 Allow elementSetName to be specified for ZOOM C record update.
922 Allow waitAction to be specified for ZOOM C based for Extended Services.
924 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
925 syntax OID. Bug introduced in YAZ 3 series.
927 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
931 Fixed bug #1157: yaz-client does not read .yazclientrc from current
932 directory. yaz-client now reads commands from file given by option -f
933 if specified; then tries to read .yazclientrc in current directory.
934 Failing that, it reads .yazclientrc from user's home directory.
936 Added support for correlationInfo Note and ID for Record Update via
939 Added yaz-client command querycharset which specifies character set for
940 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
941 (termListAndStartPoint).
943 Charset ISO5428:1984 is an alias for ISO5428-1984.
945 Implemented a way to perform scan in a result set using Z39.50. This
946 is achieved by attaching the result set name in the characterInfo
947 (type InternationalString) of OtherInformation in the Scan Request PDU.
948 The result set is identified in the otherinformation by the new OID:
949 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
950 This allows for scan in result set and faceted search . Zebra did some
951 of this in the APT term using attribute type 8 and value being result
952 set. Using the OtherInformation approach for this is cleaner and easier
953 to work with in proxies and the like. This facility can be used in
954 yaz-client using new command setscan which takes a result set as first
955 argument, start position (APT) as second.
957 Changed decoding of SRU XML packed records to deal with servers that
958 have recordData with XML data with multiple root nodes. Also make
959 comparison for recordPacking case insensitive. Again, one server
960 returns "XML" where others return "xml".
962 For SRU responses allow Content-Type application/xml as well as text/xml.
966 Fixed bug in character set conversion of BER strings. Bug introduced
971 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
973 For OID class, use oid_class consistently.
975 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
978 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
979 character set for bibliographic information interchange". By Giannis Kosmas.
981 Added documentation on new OID API.
985 Changes to generic frontend server interface: added new member
986 'query_charset' for bend_initrequest structure. A backend init handler
987 should set this member to its native character set for query terms.
988 When defined, the frontend server logic will announce this character set
989 to a client if the negotiationModel bit is set by the client. All server
990 implementors are encouraged to specify this. If a backend server does not
991 specify this a warning is issued using yaz_log(YLOG_WARN,..).
993 Added CCL utility to remove terms (stop words) from resulting RPN
994 tree. This is handled by functions with prefix ccl_stop_words_ .
996 New ZOOM C option, "rpnCharset", which allows client-side conversion of
997 terms in RPN queries.
999 Clean-up the CCL API. Moved some internal structures from ccl.h to
1000 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1001 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1002 This is replaced by ccl_parser_find_str which takes a string instead.
1004 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1005 libyaz.la is the core of YAZ except the generic frontend server and
1006 does not depend on POSIX threads anymore. libyaz_server.la is the
1007 generic frontend server facilities and uses POSIX thread functionality
1008 if available. The libyaz.la no longer depends on POSIX threads because
1009 the number of global structures is limited. NMEM no longer re-uses blocks
1010 between threads ; it simply free's memory immediately but allocates in
1011 "large" chunks as usual. We don't expect any performance penalties
1012 because of this. The yaz_log system is still using a global log_level so
1013 caution must be taken when modifying it with yaz_log_init_.. +
1014 yaz_log_mask_str. This, however, should not cause any trouble because
1015 these functions are called during initialization of application code
1016 anyway. `yaz-config --libs server` returns libs for server applications;
1017 `yaz-config --libs` returns libs for non-server applications.
1019 New OID database - with public definitions in oid_db.h. Removed old OID
1020 database including the head oid.h and definitions such as enum oid_value
1021 and struct oident. The new OID database uses the same string names as
1022 before but the 'protocol' is gone. There are now only two representations
1023 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1024 converts from string to OID; functions with prefix yaz_oid_to_string
1025 converts the other way.
1027 Change to emit_term() in CQL-to-PQF query translation: when a term has
1028 the /regexp relation modifier, do not process it for leading and
1029 trailing "^" and "*", which have quite different meanings in regular
1032 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1033 write handlers no longer carries a 'last' parameter. This will make
1034 yaz_iconv flush "less" characters. A flush is performed by call to
1035 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1037 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1038 removed, because function yaz_query_to_wrbuf does the same.
1040 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1041 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1043 Deprecated MARC utility functions removed.
1045 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1048 Branch split: YAZ_2_1_55_branch
1050 --- 2.1.54 2007/03/16
1052 Fix to ZOOM-C so that transparent reconnection is properly handled on
1053 connections that are in asynchronous mode.
1055 Fixed compilation on OpenBSD 4.0.
1057 Large strings in GRS-1 records are now properly displayed in yaz-client.
1059 Added character conversion support for "advancegreek"; based on patch from
1062 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1063 sequence is met. Before the error was not set so it would be unknown.
1065 Adjust yaz-marcdump MARC reader so that it skips until record separator
1068 --- 2.1.52 2007/03/07
1070 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1071 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1072 fd_set structure used as a bitmask for the FDs to be selected on.
1074 Using ACX_PTHREAD macro to check for POSIX threads.
1076 Fixed have-vsnprintf check.
1078 --- 2.1.50 2007/02/23
1080 Fixes for configure on BSD. Bug #900.
1082 Added snprintf/vsnprintf wrappers for systems that don't have
1083 limits (heavens forbid).
1085 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1086 created before all previous tasks were completed and removed from the
1087 task queue, the new task could be removed by a mistake.
1089 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1091 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1093 Fixed bug #832: Problem with MARC/charset in yaz-client.
1095 Fixed bug #668: save command line history for yaz-client.
1097 Fixed bug #830: pkg-config support.
1099 --- 2.1.48 2007/01/23
1101 Extended ZOOM result set options with two options that may be read by
1102 a client: resultSetStatus and presentStatus with values as specified for
1104 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1106 Fixed bug #827: Using SSL fails on Debian etch.
1108 Fixed bug #826: Weird looking chars for set of MARC records.
1110 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1111 that is treated as an ItemOrder with itemRequest being an XML document
1112 external. The value of "doc" is the content.
1114 Extended the GFS search facility. New member of bend_search_rr
1115 'estimated_hit_count' signals that hits is known to be an estmate
1116 (higher or lower than real hit count). New member 'partial_resultset'
1117 signals that the search was partial (hit count is lower or equal than
1118 real hit count). For Z39.50, the information is stored in resultSetStatus
1119 member of SearchResponse APDU. For SRU, the information is signalled
1120 via SRU diagnostic 59: "Result set created with valid partial results
1123 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1125 --- 2.1.46 2007/01/13
1127 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1129 Added ZOOM_connection_peek_event.
1131 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1132 the following new functions:
1133 ZOOM_event_nonblock, ZOOM_connection_process,
1134 ZOOM_connection_get_{socket,mask,timeout},
1135 ZOOM_connection_fire_event_{timeout,socket}.
1136 The existing blocking event handler, ZOOM_event, is a wrapper for the
1137 + blocking ZOOM_event_sys_{poll,select}.
1139 Implemented function ccl_xml_config which parses XML version of CCL
1140 configuration (bug #798).
1142 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1144 Added timings utility (yaz/timing.h)
1146 --- 2.1.44 2007/01/03
1148 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1151 Fixed bug #779: Rotation of apdu.log fails.
1153 Fixed for character set conversions:
1154 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1155 Honor G1 set in MARC-8 decoding.
1157 --- 2.1.42 2006/12/17
1159 Fixed bug #775: char conversion does not handle Alternative UTF-8
1162 Implemented function yaz_marc_read_line which parses MARC line format
1163 records. There is a wealth of formats out there. So far, this function
1164 reads line records produced by yaz_marc_write_line.
1166 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1167 more generic and easier to remember(!) options: -i format and -o format
1168 which specifies input format and output format respectively - where
1169 format is one of "marc", "marcxml", "line", "marcxchange".
1171 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1172 does not print anything except warnings for records.
1174 For yaz-marcdump, added support for MARC split into files (-s) with a given
1177 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1178 spec, at http://www.loc.gov/standards/sru/record-update/
1179 This has changed the binary layout of the following structs:
1180 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1181 bend_update_rr . Patch by Ko van der Sloot.
1183 Added GFS utility function bend_assoc_is_alive which returns 1 if
1184 association is still alive (client is connected); 0 otherwise (client
1185 closed connection). This allows busy servers to stop working for
1188 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1189 been a separate piece of software. This version of ziffy has been modified
1190 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1192 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1194 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1195 Client code may now interrogate options such as "init_opt_sort" to
1196 find out whether the server claims to support various options.
1198 --- 2.1.40 2006/11/27
1200 Added utilities yaz_{set,get}_esn to set/get element set name from
1203 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1204 of YAZ and has been so since YAZ 2.1.10.
1206 Implemented ZOOM_record_error which returns error information for
1207 record (surrogate diagnostic).
1209 --- 2.1.38 2006/10/31
1211 Updates for SRU Update by Ko van der Sloot:
1212 1. Changed name from "operation" to "action"
1213 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1214 versions in the code, marked as 'backward compatible'.
1215 3. Added diagnostics for SRU Update.
1217 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1219 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1221 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1223 For GFS, fixed problem with SRU diagnostic 'First record position out of
1224 range' being issued for 0 hits.
1226 zoomtst10 part of Windows Build.
1228 --- 2.1.36 2006/10/13
1230 Implemented yaz_filepath_comp which splits a path into file path
1231 components (required by Zebra 2.0.3+).
1233 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1234 BSD inspired license until now so this should not have any real impact on
1235 anybody. See http://www.opensource.org/licenses/bsd-license.php
1237 Fixed bug #687: Missing log lines.
1239 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1242 Fixed bug #689: SRU diagnostics to be added.
1244 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1245 whether a connection is idle (no more work do do).
1247 --- 2.1.34 2006/10/04
1249 Change type of optval from long to int for invocation of setsockopt with
1250 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1252 Added support for specifying the max log file size for the Generic
1253 Frontend Server. The size is given with option -r.
1255 --- 2.1.32 2006/09/21
1257 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1259 --- 2.1.30 2006/09/17
1261 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1264 Fixed bug in Generic Frontend Server that could cause a server to stop
1265 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1267 For the generic frontend server, the maximum record size is used as maximum
1268 size of incoming packages (SRU + Z39.50). The value until was previously
1269 only used in Z39.50 Init negotiation and, later, in a session controlled
1270 sizes of records returned. This is controlled using -k option. It can be
1271 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1273 --- 2.1.28 2006/09/04
1275 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1278 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1280 New option for yaz-marcdump -lpos=value which allows setting a portion
1281 of MARC header to a certain value.
1283 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1285 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1286 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1288 --- 2.1.26 2006/08/15
1290 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1293 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1295 --- 2.1.24 2006/08/08
1297 Fixed MARC ISO2709 encoding routines to deal with character set
1300 Minor changes to GFS logging. Database included in search request log
1303 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1304 cached/multiple records.
1306 Shared libraries are built by default on Unix+configure.
1308 Changed cql2pqf transformation to use a different evaluation order. The
1309 new order is: always, relation, structure, position, truncation, index
1310 and relationModifier. Old order was: always, relation, relationModifier,
1311 structure, index, position, truncation. Note that the the latter ones
1312 override former ones for identical attributes.. The new scheme means that
1313 it is possible to override any existing attribute with a relationModifier.
1314 And also that it is possible to override everything for the index rule
1315 (except the ones listed in relationModifier). No order is perfect but this
1316 one, we believe, covers more real cases.. The "always" should have been
1317 called "default", since the attributes there can be overridden with all
1320 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1321 compilation phase, but also for yaz-config --cflags output. This allows
1322 us to have public headers with Libxml2 stuff in them . It should also,
1323 eventually, make Libxml2 checks redundant in packages using YAZ, such
1326 --- 2.1.22 2006/06/15
1328 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1329 stored in uri, message and details.. Previously diagnostics were stored
1330 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1331 compatibility.. but he's probably the only one affected, so.
1333 Added support for CCL, compiled on the client side, in ZOOM-C. This
1334 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1335 input; the resulting query objects can be used for for searching with
1336 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1338 YAZ' configure searches for OpenSSL by default.
1340 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1341 SL_CTX_use_certificate_file. See
1342 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1343 for more info. Thanks to Ko van der Sloot.
1345 --- 2.1.20 2006/06/02
1347 Bug #600: SRU GET, POST support for yaz-client. Introduced
1348 command 'sru' which selects method SOAP/GET/POST.
1350 Allow missingValueAction to be specified for the sortspec string -
1351 function yaz_sort_spec. By default, the missing value action is null.
1352 Use ! to specify "abort". Use = followed by stringvalue to specify default
1355 Ensured that Present-handler (if defined) is called in GFS before any call to
1356 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1357 searchRetrieve requests.
1359 Documentation for YAZ is now based on the Docbook XML/XSLT using
1360 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1361 is no longer depending on jade/openjade or docbook-to-man scripts.
1362 PDF is no longer part of the distribution - but can optionally be
1363 made using DSSSL/jadetex or FOP.
1365 Added retrieval handling support in Generic Frontend Server to support
1366 conversion between MARC/XML as well as XSLTtransforms. See
1367 etc/yazgfs.xml for an example.
1369 Added Authentication support to Generic Frontend Server in SRU
1370 mode. Authentication using HTTP Basic is supported, as is the use
1371 of 'x-username' and 'x-password' parameters in the request itself.
1373 Added support for a new character set MARC8s identical to MARC8 except
1374 that it converts combined characters to single Unicode characters in the
1375 Latin-1 range (when possible).
1377 --- 2.1.18 2006/04/24
1379 ASN.1 compiler 0.4: generates brief Doxygen file header for
1380 generated .h/.c files.
1382 Utility yaz_iconv now supports conversion to MARC-8.
1384 New facilities for the MARC module. The reading - and writing of
1385 content are separate methods for the yaz_marc_t handle. The following
1386 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1387 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1388 format). Write functions have prefix yaz_marc_write_.. The existing
1389 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1390 available. Removed support for OAI-MARC and simplexml (not the
1391 simplexml from PHP5).
1393 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1394 to be returned for this connection.
1396 --- 2.1.16 2006/03/31
1398 Allow multiple languages and charsets to be specified with
1399 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1400 negcharset iso-8859-1,utf-8
1402 Translation of proximity nodes from CQL into PQF now works.
1404 Moved to automake 1.8, 1.9.
1406 Added function yaz_log_set_handler which allows a log handler to be
1407 installed. This handler will be called for all log messages. Output
1408 to file is also produced; but that can be disabled by passing NULL
1409 fname to yaz_log_init_file.
1411 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1413 For SRW (including GFS), accept application/soap+xml as content-type
1416 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1417 produces NO stylesheet reference even if a default stylesheet is specified
1420 --- 2.1.14 2006/03/14
1422 Updated Windows package to include yazd.dll + yazd.lib for the
1423 Development component.
1425 If the environment variable YAZ_LOG is set, then it is used as a
1426 string indicating the default level of logging to use if not
1427 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1428 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1429 used as before. So, for example, to omit warnings from YAZ logging,
1430 export YAZ_LOG=-warn
1432 cql_transform() now map structure and other attributes before indexes,
1433 so that index-specific structures and other attributes can override
1434 defaults. So now a combination of mapping specifications such as:
1436 index.dc.date = 1=date-modified 4=5
1437 does the right thing.
1439 cql_transform() now also respects the "always" mapping specification,
1440 which establishes an initial set of attributes to be used for all
1441 terms except where overridden by more specific attributes associated
1442 with the index, relation or modifier.
1444 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1445 which mode to use; one of "post", "get" or "soap" (SRW, default).
1447 Fixes for yaz_iconv routines: changed trie-based character set conversions
1448 to use only non-negative values for bit fields due to Sun's C compiler not
1449 supporting negative values.
1451 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1452 sequences where not read correctly. Fix by Rustam Usmanov.
1454 Updated win/makefile to use options, settings which makes things
1455 compile with VS C 2005.
1457 --- 2.1.12 2006/02/01
1459 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1461 In ZOOM socket code, use select instead of poll on MacOSX.
1463 ZOOM-C now support client-side compilation of CQL into RPN that is
1464 sent to the server, enabling CQL to be used against all Z39.50
1465 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1466 ZOOM_query object, and submit it using ZOOM_connection_search().
1467 The CQL-to-RPN translation uses a configuration file, the name of
1468 which must be specified in the Connection's "cqlfile" option.
1470 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1471 function, which takes as its start-term parameter a ZOOM_query object
1472 (which may have had either CQL or RPN set into it).
1475 --- 2.1.10 2005/11/29
1477 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1478 GFS to support this as well. Backend handler, bend_srw_update, does the
1479 update work. Code contributed by Ko van der Sloot.
1481 Allow retrieval of Search Result-1 information in ZOOM by the use of
1482 options that are attached to a result set. ZOOM documentation updated
1485 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1486 UTF-8 conversion. Patch by Raj Patel.
1488 Added option -m to GFS to control formatting of timestamps in log file.
1490 Added 'exit' as synonym for 'quit' in yaz-client
1492 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1493 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1494 for the new members. Patch by Ko van der Sloot.
1496 Added support for SRU POST. It is supported for content-type
1497 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1499 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1500 Instead make the library libyaz.la multi-threaded. Threading as a whole
1501 can still be disabled by configure option --disable-threads. Previosly,
1502 with older GLIBCs there were problems with MT libs under Apache. This
1503 has now been fixed a long time ago.
1505 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1508 CQL module modified to be case insensitive for relations/indexes/operations.
1510 Fixed bug in CQL transform code: incorrect value relationModifieder
1513 Added 'show all' command for yaz-client which retrieves all results
1516 Added new yaz-client, xmles, which takes a (private) OID and
1517 a document to be sent as an extended service request.
1519 Describe new yaz-client commands wait_response and set_auto_wait.
1521 Increase TCP/IP listener backlog from 3 (which I am guessing was
1522 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1523 that the socket will queue as many incoming connections as it's able
1524 to handle ongoing connections. In other words, it will never now
1525 refuse a connection that it would be able to handle merely because
1526 it's not got around to accepting() enough of the pending connections
1527 yet. This is the behaviour anyway under Linux, where the listen()
1528 argument is ignored; but not under BSD and on systems such as
1529 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1530 YAZ-based servers should now be uniform across operating systems in
1533 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1534 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1535 This allows yaz-marcdump to read large MARC batches (>2 GB).
1537 Modified all YAZ source files - except the source which is auto-generated
1538 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1541 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1542 corresponding to the existing *_setl() function. These allow option
1543 values containing arbitrary valuues.
1545 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1546 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1547 except that it returns an indicator of whether or not the sort
1548 criterion was accepted (0 for OK, -1 for invalid).
1550 --- 2.1.8 2005/06/07
1552 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1553 MARC output rather than returning "new" buffer.
1555 yaz-client warns about unknown init options.
1557 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1559 --- 2.1.6 2005/05/24
1561 Added support for SRW sort in Generic Frontend Server. Patch
1562 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1563 sortKeys - or NULL if none is provided.
1565 Fixed bug #307: It was impossible to specify indefinite/no timeout
1566 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1569 Added support for multiple languages and charsets to be specified in
1570 ZOOM. Each charset/language is separated by a blank. If negotiation is
1571 in effect in init-response, Option
1572 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1573 Code based on patch by Vasiliy Osadchuk.
1575 Fixed bug #306: infinite recursion that occurred when calling
1576 yaz_log_level_init as the first call (before other log level or
1579 Fixed bug in scan handling in front end server: if preferred-Position-In-
1580 Response was non-present, a NULL pointer referece was performed.
1582 --- 2.1.4 2005/04/26
1584 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1585 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1586 now defined for all those error codes. So instead of putting 109 in
1587 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1588 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1590 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1593 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1595 Program yaz-client now exits and produces an error message if multiple
1596 Z39.50 servers are specified on the command line (none or one allowed
1599 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1602 --- 2.1.2 2005/03/16
1604 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1606 Fixed bug #272: Preserve spacing for CCL terms.
1608 --- 2.1.0 2005/03/14
1610 Added support for virtual hosts and multiple backend servers for
1611 the YAZ frontend server. The configution is XML based and
1612 support specificition of CQL to RPN mappings and explain information.
1613 See section "Virtual Hosts" in the YAZ manual.
1615 Extended OPAC display utility. OPAC display utility renders
1616 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1617 to supplement yaz_marc_decode_wrbuf.
1619 Fixed a bug in MARC decoder that could caused it to crash for some
1620 invalid MARC records. More diagnostics and warnings where added in
1621 XML output (warnings, etc are stored in comments).
1623 --- 2.0.34 2005/02/08
1625 Fixes for UNIX domain sockets. Bug #261.
1627 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1629 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1630 Added yaz_marc_subfield_str which defines subfield lead string which is
1631 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1632 yaz_marc_endline_str which defines end of fields string used in
1633 YAZ_MARC_LINE format. Default string is newline.
1635 Experimental support for MarcXChange. This format can be produced
1636 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1637 http://www.bs.dk/standards/MarcXchange.xsd
1639 Added yaz-client commands scansize that sets maximum number of
1640 entries to be returned by scan.
1642 --- 2.0.32 2005/01/11
1644 Added support for SRW scan in yaz-client and Generic Frontend Server.
1646 * Added whereInList member to SRW Scan Term.
1648 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1650 Fixed NMEM system to return aligned blocks on the smallest boundaries
1651 that are suitably aligned for all possible types on the particular
1652 architecture YAZ is being built for.
1654 --- 2.0.30 2005/01/04
1656 Fixed numerious warnings that was issued with newer versions of GCC.
1658 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1659 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1662 Make YAZ Generic Frontend Server slightly faster.
1664 Enhance (and reduce) logging for Generic Frontend Server.
1666 Revert YAZ log system so that it flushes every write operation
1667 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1669 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1670 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1671 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1672 will effectively disable old definitions.
1674 --- 2.0.28 2004/11/09
1676 Added yaz_log_time_format which specifies log format using
1679 Added yaz_log_module_level which returns mask for a module. Value
1680 is non-zero mask a if module is enabled; zero if disabled.
1682 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1683 in include/yaz/cql.h.
1685 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1687 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1689 Fixed bug #172: RPM builds does not enable SSL.
1691 Doxyfile.in part of dist. Doxyfile generated by configure.
1693 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1694 are given and the corresponding component does not exist.
1696 Extend CCL documentation in YAZ reference. Describe r=r.
1698 --- 2.0.26 2004/10/01
1700 Fixed MARC->MARCXML conversion to properly deal with
1701 fields, subfields, indicators having non-ASCII characters.
1703 Fixed MARC->MARCXML conversion so that ASCII control characters
1704 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1707 Added YAZ GFS support for conversion from Z39.50 surrogate
1708 diagnostics to SRW surrogate diagnostics.
1710 Bug fix: YAZ GFS did not return schema in explainResponse.
1712 --- 2.0.25 2004/09/30
1714 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1715 now converts recordSchema to elementSetName as well as schema URI.
1717 Fixed bug in COMSTACK that prevented HTTP request packages from being
1720 --- 2.0.24 2004/09/29
1722 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1723 does not require white-space before and after the dash in a range, e.g.
1724 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1727 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1728 due to new GCC removing "redundant" code.
1730 Added yaz-client commands scanpos and scanstep that sets preferred
1731 position and step-size for scan.
1733 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1735 Added CCL utility ccl_qual_buf which parses one or more CCL
1736 spec lines in a buffer.
1738 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1739 of name and value - ignoring empty lines and comments.
1741 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1743 Added odr_get_element_path which returns current element path for an
1744 ODR handle. This utility is useful in error handling or user-defined
1747 Added ODR_PRINT utility odr_set_stream which is is a more generic
1748 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1749 to a write function and pointer to close function. The close function - if
1750 non-NULL - will be called during odr_destroy.
1752 Fixed bug in CCL parser where truncation char was not removed from
1753 right side when truncation=both was in effect.
1755 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1758 --- 2.0.23 2004/08/11
1760 Fix buffer overrun in CQL parser when dealing with proximity (%).
1762 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1763 to UTF-8/UCS conversion is now only based on codetables.xml.
1765 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1767 --- 2.0.22 2004/08/06
1769 Add support for more "commit changes" in ZOOM (uses Extended Services).
1771 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1774 Yet another small fix for configure of SSL.
1776 --- 2.0.21 2004/05/14
1778 Fix SSL libs for configure when --with-openssl=DIR is given.
1780 --- 2.0.20 2004/05/10
1782 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1784 SSL comstack now uses yaz.pem certificate file on server side
1785 by default. Certificate filename can be configured by calling
1786 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1788 Fix bug regarding multiple calls to ZOOM_connection_connect.
1790 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1792 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1793 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1795 ZOOM now allows inspection of X509 peer certificate for verification.
1796 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1798 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1799 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1800 as "modular" but it simplifies things.
1802 Added cs_get_peer_certificate to that returns peer X509 PEM.
1804 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1805 NULL if SSL is unavailable.
1807 Documentation about MARC decoding tools.
1809 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1811 --- 2.0.19 2004/03/30
1813 Rename CHANGELOG to NEWS to follow GNU style packing.
1815 Fix bug with missing initialization of member in init_diagnostics.
1816 This bug affects threaded version of GFS server.
1818 --- 2.0.18 2004/03/20
1820 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1823 Ensure zlib.dll is packed with Windows install.
1825 --- 2.0.17 2004/03/17
1827 Fix encoding of xsd:string to use text instead of CDATA.
1829 Fix endless loop in CQL parser with unbalanced ".
1831 Use a more compact way to store MARC-8 conversion tables.
1833 --- 2.0.16 2004/03/16 Debian only
1835 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1838 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1843 --- 2.0.15 2004/03/01
1845 Another fix for decoding of XML packed records.
1847 --- 2.0.14 2004/02/25
1849 Fixes for Chunked encoding. White space not ignored after length spec.
1851 Update NS and use default NS for SRW diagnostic elements.
1853 --- 2.0.13 2004/02/23
1855 Implement ZOOM_resultset_cache_reset which resets record cache.
1857 Implement ZOOM_resultset_sort which sorts a result set.
1859 Implement chunked HTTP transfer.
1861 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1863 --- 2.0.12 2004/02/16
1865 Added member 'schema' to bend_explain_rr structure so that backend
1866 can specify explain record identifier. Defaults to Zeerex 2.0.
1868 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1870 --- 2.0.11 2004/02/16
1872 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1875 Added init command for yaz-client which sends "extra" init request.
1877 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1878 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1880 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1882 Make ZOOM error code for "invalid query".
1884 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1886 --- 2.0.10 2004/02/05
1888 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1891 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1893 Added option -p <file> to make Generic Frontend Server to write PID file.
1895 Added option -D to put Generic Frontend Server in background on its own.
1897 Make ZOOM C recognize option "password". If unset, "pass" is used
1898 (for backwards compatibility).
1900 Fixed a bug in Generic Frontend Server that could make it crash if a
1901 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1904 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1905 Must be issued before open, in order to be in effect.
1907 --- 2.0.9-6 2004/01/12 Debian/Windows
1909 Make the SRU server more picky WRT unknown params, etc.
1911 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1913 New YAZ client command, options, that sets Z39.50 options.
1915 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1916 options from a string of tokens (one token for each option bit).
1918 Update SRW diagnostic code messages.
1920 --- 2.0.9-5 2004/01/07 Debian/Windows
1922 Handle user defined stylesheet for SRW/SRU.
1924 --- 2.0.9-4 2004/01/06 Debian/Windows
1926 Fix bug in decoding of Content-Length.
1928 --- 2.0.9-3 2004/01/06 Debian/Windows
1930 Fix a bug with decoding of XML packed records.
1932 --- 2.0.9-2 2004/01/05 Debian only
1934 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1936 Fix bug in SRW/SRU diagnostics decoding.
1938 --- 2.0.9 2004/01/05
1940 Fixed bug in Generic Frontend Server which could drop records exceeding
1941 preferred message size. Reported and fixed by Irina Dijour.
1943 Fixed calculation of package size for structured records in Generic
1944 Frontend Server. Reported and fixed by Irina Dijour.
1946 Fixed namespace for SRW/SRU diagnostics.
1948 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1950 --- 2.0.8 2003/12/22
1952 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1953 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1956 CQL changes to reflect recent changes to the specification:
1957 * Documentation talks about context sets instead of index sets.
1958 * Documentation talks about indexes instead of qualifiers.
1959 * The CQL-to-PQF transformer's configuration file now uses
1960 "index.set.name = <attributes>" instead of the old form
1961 "qualifier.set.name = <attributes>". (Both forms are still
1962 understood but the latter is deprecated.)
1963 * CQL terms with no explicit index specified are now interpreted as
1964 cql.serverChoice instead of srw.serverChoice (which of course
1965 behaves exactly the same.)
1967 --- 2.0.7 2003/12/16
1969 MARC conversion can now generate ISO2709 output in another
1970 character set. yaz-marcdump uses this facility if you invoke it
1973 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1974 functions from there can be used from C++.
1976 --- 2.0.6 2003/12/04
1978 Frontend server now transfers memory from decoded packages to stream
1981 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1982 references to show up.
1984 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1985 the ZOOM Abstract API. The older names for the same options are still
1986 also supported for the benefit of old applications.
1988 ZOOM-C supports "implementationId" and "implementationVersion" options
1989 to go along with "implementationName". These allow the user code to
1990 specify identification strings to be sent to servers.
1991 Add OID for the new ExtLite attribute set.
1993 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1994 as requested/supplid by Ere Maijala <ere@atp.fi>
1996 For generic frontend server, reverse the order of
1997 "toolkit-supplied / application-supplied" strings sent as implementationId,
1998 Name and Version. Also, remove the spaces around the slash. This brings
1999 the GFS in line with the behaviour of ZOOM-C on the client side.
2001 Add function ZOOM_scanset_display_term.
2003 yaz-client shows scan displayTerm if present.
2005 Utility yaz-iconv is now installed by default along with the man page
2008 Extend configure check for OpenSSL to use pkg-config where available (such
2011 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2012 server to specify uid/gid/mask for socket using the format
2013 unix:[user=uid,][group=gid,][umask=mask,]file=path
2014 If file= is omitted the existing format is assumed, e.g.
2016 in which case the mask is 0666 (rw for everybody).
2018 Major restructure of YAZ source. All source in libyaz is in src directory.
2019 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2020 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2022 Added man page for utility yaz-marcdump (used to be called marcdump).
2023 yaz-marcdump is installed by 'make install'.
2025 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2026 of incoming package failed.
2028 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2030 Change prototype of odr_perror: add const to message string.
2032 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2034 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2035 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2036 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2037 DNS lookup. There should not be any compatibility problems with this
2038 assuming that blocking=1 or 0 is used.
2040 Fix bad reference in UNIX comstack in function cs_addrstr.
2042 Fix for compilation on AIX.
2044 The generic front-end server (server/seshigh.c) now supports returning
2045 Init diagnostics to the client in User-information-field, in
2046 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2049 --- 2.0.4 2003/09/04
2051 Allow any CQL relation (not just all,any,exact,scr).
2053 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2054 that features the same UI.
2056 Implemented command update0 in YAZ client which is equivalent to
2057 update but uses old of Ext Update ASN.1.
2059 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2060 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2061 Previously no OID was used for this info.
2063 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2064 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2065 returns 'malformed search term' otherwise.
2067 SortResponse member resultCount now set to NULL in sort handler of
2070 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2073 Add three new utility functions for translating OIDs between various
2074 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2075 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2076 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2077 char *oid_to_dotstring(const int *oid, char *oidbuf);
2078 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2080 Reverted modifications for ES Update definition for z_IU0Update
2081 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2082 is back to YAZ 2.0.2.
2084 String value attributes for CCL parser.
2086 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2087 which their FirstSearch server returns in Init responses, sometimes
2088 carrying useful diagnostic information when Init fails. This has the
2089 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2090 "z39.50/oclcui.asn", where its definition is somewhat different from
2091 what OCLC document on their web-site, as required to interoperate with
2094 Support for anonymous authentication in yaz-client. Use the command
2097 * Fix the OID of the Index Data-local "admin" Extended Service from
2098 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2099 the 1000, which indicates a locally-defined OID, was a mistake.
2101 --- 2.0.3 2003/06/20
2103 Fix CCL directive @case handling so that it affects string match for
2104 both CCL keywords and qualifiers.
2106 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2107 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2108 Decoder has been updated with ASN.1 changes as listed in
2109 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2110 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2111 z_IUUpdate, remains unchanged.
2113 ZOOM_record_get may now return a record in a specific character set.
2114 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2115 "from" is the character set of record as returned by target. "to" is
2116 the character set to be returned. If omitted, "to" is UTF-8.
2118 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2120 New ODR utility, odr_getelement, which returns name of element for
2121 which encoding/decoding failed.
2123 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2124 in cases where a required element was omitted.
2126 Bug fix: some MARC8 sequences were not converted.
2128 New ZOOM option "step" which specifies number of records to be
2129 retrieved in one chunk. Used in conjunction with "start" and "count".
2131 SRW support for yaz-client. Use scheme http: to use it, e.g.
2134 yaz-client no longer does (un)intelligent character set conversions
2135 by default. Can be enabled with charset and marc_charset commands.
2137 xmalloc trace fix for 64-bit systems such as DEC alpha.
2139 Solaris 2.6 compile fix.
2141 New function, cql_strerror() translates SRW error codes, as returned
2142 by cql_transform_error(), into human-readable English strings. Used
2143 in yaz-client diagnostics when appropriate.
2145 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2146 converts it into a type-1 query which is sent to the server. This
2147 makes CQL available for use with all Z-servers, as opposed to the tiny
2148 minority that can handle CQL queries themselves.
2150 --- 2.0.2 2003/04/28
2152 New Debian package layout similar to the Redhat Package layout.
2154 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2155 and search result respectively.
2157 --- 2.0.1 2003/04/25
2159 Redhat package is now several packages: libyaz (runtime libraries),
2160 libyaz-devel (development and documentation, and yaz (utility programs).
2161 Package spec file by Morten Bogeskov.
2163 New member 'schema' in struct bend_fetch_rr which the name of requested
2164 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2165 handler MAY set this to reflect the schema of the returned record.
2167 New member 'display_term' in struct scan_entry. GFS now sets member entries
2168 and allocates scan entries to be filled by user scan handler. In previous
2169 version, entries member was allocated by the scan handler. That still works,
2170 but the GFS will ignore member display_term - assuming it was NOT set by
2171 the handler. The fact that the GFS now allocates the entries both allows
2172 for new members and makes a scan handler easier to write.
2174 Fix CQL lex buffer overflow.
2176 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2177 SRU default recordPacking is string.
2179 SRU protocol support for frontend server.
2181 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2183 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2185 Added scan for the ZOOM shell (zoomsh).
2189 * String Identifers for Schemas (Amendment 5).
2190 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2191 Old definition for schema
2192 Odr_oid *schema; /* OPT */
2197 Z_InternationalString *uri;
2198 #define Z_Schema_oid 1
2199 #define Z_Schema_uri 2
2202 * resultCount parameter to Sort Response (Amendment 1).
2203 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2205 Support for SRW 1.0 over HTTP. This is an optional feature and
2206 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2209 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2210 on the same port. SRW SearchRetrieveRequests are mapped
2211 to bend_init,bend_search,bend_fetch,bend_close.
2213 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2215 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2216 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2218 ZOOM connections are SRW based if schem http is used for hostname
2219 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2220 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2222 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2223 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2224 distance=n, order=true/false, relation=le, prox unit=word. If
2225 n is omitted, distance 1 is used.
2227 Fixed problem with C compiler include path in wrong order.
2229 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2230 on Solaris. Patch from Ko van der Sloot.
2232 New MARC decode API. All new functions operate on a yaz_marc_t
2233 handle. The most important new functions are: yaz_marc_create,
2234 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2235 decode and destroy respectively. Decoder can produce formats
2236 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2237 include/yaz/marcdisp.h.
2239 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2240 to UTF-8, UCS-32, wchar_t or Latin-1.
2242 * Prototypes for yaz_iconv_-functions moved to separate header
2243 include/yaz/yaz-iconv.h.
2245 Make a few private functions 'static' in unix.c. This prevents
2246 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2248 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2249 are set when Init Response is received.
2251 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2252 but returns diagnostic set as well.
2254 New function yaz_strerror which is a portable wrapper for
2255 strerror/strerror_r/GetLastMessage.
2257 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2258 is returned for MARC. If type is "oai", then OAI MARC is returned.
2260 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2263 --- 1.9.2 2002/11/26
2265 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2267 Fix bad race conditions on SIGTERM and terminate gracefully in
2270 Move retrieval (data1) module to Zebra since nobody seems to be
2273 Add GRS-1 render for ZOOM using same format as yaz-client.
2275 --- 1.9.1 2002/10/05
2277 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2279 Fix broken ESpec handling in data1 module.
2281 SGML reader parses comments and makes them part of the data1 tree.
2283 Added several type casts so that YAZ compiles as C++ code.
2285 ZOOM didn't handle PDU encoding failures properly.
2287 Added more Bib-1 diagnostics (approved extensions).
2289 GNU configure: better check for iconv.
2291 More portable use of accept, getpeername. Check for socklen_t. Use
2292 int/size_t if socklen_t is not defined.
2296 PQF parser rejects bad queries - including those with extra
2297 characters in them. PQF parser used to silently ignore that.
2298 Cleaner API for PQF added, which allows you to get detailed
2299 error information for bad queries (see yaz/pquery.h).
2301 Fixed bug in ZOOM_record_get for type "database".
2303 Implemented mini iconv library supporting conversions between
2304 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2306 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2308 --- 1.8.9 2002/08/20
2310 Fixed ZOOM C record cache so that preferredRecordSyntax and
2311 elementSetName is used to check for already fetched records.
2313 --- 1.8.8 2002/08/02
2315 Added three members in bend_initrequest structure to facilitate
2316 character set negotiation.
2318 Fixed a bug in frontend server that could cause indefinite
2319 loops under rare conditions.
2321 Revised character set utilities (charneg.h) so that encoding
2322 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2324 For PQF, directive @term <type> sets term type for Scan/Search.
2325 Here <type> is general, string, numeric, null. The term type
2326 is inherited - just like @attr.
2328 New call odr_set_charset that sets character set conversion for
2329 international-strings on a ODR stream. Prototype is:
2330 int odr_set_charset(ODR o, const char *to, const char *from);
2331 The InternationalString is still represented as C string in YAZ
2332 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2333 won't). On the protocol level, you can use any encoding.
2335 Support for UNIX sockets in ZOOM.
2337 Solaris recv sometimes returns errno == ENOENT. It is treated as
2338 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2340 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2341 both client and server. Code by Morten Bogeskov.
2343 --- 1.8.7 2002/05/22
2345 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2346 that they can be used directly from Visual Basic. You must recompile
2347 your windows APP if you're using ZOOM.
2349 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2350 Commands "lang" and "charset" sets language and character set respectively.
2351 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2352 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2354 Attributes from multiple CCL fields may be OR'ed rather than merged
2355 using directive "@field or". Fields are still merged by default -
2356 equivalent to "@field merge".
2358 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2361 Fixed bug in zget for parameter ExtendedServicesResponse.
2365 --- 1.8.6 2002/03/25
2367 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2369 Client displays USR.1:SearchResult-1 (hits per term).
2371 Additional Search Info for search in Generic Frontend Server.
2373 Fixed CCL parsing of "field=s".
2375 WIN32 installer - using the excellent NSIS software from nullsoft.
2377 Fixed CCL parsing of "field = - <number>".
2379 Added function yaz_marc_decode that decodes MARC for line mode
2380 display or XML (similar to that used by JZKit).
2382 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2383 Z39.50. But ISO/ILL was, however.
2385 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2386 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2388 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2389 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2391 --- 1.8.5 2002/02/03
2393 New YAZ client features: Command completion and new commands:
2394 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2395 Code provided by Jacob Poulsen.
2397 New call oid_trav, that visits all registered OIDs via callback.
2399 Function ZOOM_record_get now returns const char pointer rather than
2400 void pointer. It saves a lot of type casts.
2402 For YAZ client, command "auth" now allows you to set authentication
2403 in IdPass style. It is enabled when three tokens are given - order
2404 is user, group and password.
2406 Fix memory leaks in MARC record handling for ZOOM.
2408 New option for YAZ client, -k <kilobytes> that sets
2409 maximum record size. Similar to -k option for generic frontend
2410 server and yaz-ztest.
2412 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2414 Prefix query parser reports "fail" when bad attribute set is given.
2416 Fix in MARC decoder. Proximity logging. Fix for attribute set
2417 in scan handler for server. Patches by Shigeru Ishida.
2419 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2422 Configure option --with-openssl=<dir> now works when a directory is
2423 specified. Patch provided by Morten Bogeskov.
2425 New option for YAZ client, -u <auth>, that sets authentication.
2427 ZOOM fix: error information was sometimes "missing", since error
2428 was cleared/reset too when it shouldn't.
2430 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2432 --- 1.8.4 2002/01/04
2434 Scan for ZOOM API. New object ZOOM_scanset. New functions
2435 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2436 ZOOM_scanset_destroy.
2438 New ZOOM function, ZOOM_connection_last_event, that returns type
2439 of last event (such as "receive data", "send data", "apdu received",
2442 New ZOOM option, schema, that specifies schema for retrieval.
2444 New CCL feature. Qualifiers can be aliases for one or more
2445 other qualifiers (if more than one is given, OR is used).
2447 ZOOM uses named result sets if target supports it.
2449 Two new YAZ client commands: . (dot, which sources a script of YAZ
2450 client commands), and ! (to execute shell command.). Implemented
2453 Working on Debian packages.
2455 --- 1.8.3 2001/11/19
2457 YAZ client enables named result sets only if target supports it.
2459 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2461 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2462 with key="host" to get same result.
2464 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2465 Function Z3950_resultset_record(s) returns references to records
2466 "owned" by resultset. To become owner use Z3950_record_clone.
2468 Function z_ext_record handles Extended Services. Thanks to
2471 --- 1.8.2 2001/11/12
2473 CCL Parser fix: ignore token comma when dealing with and-lists.
2475 Documentation updates for COMSTACK.
2477 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2478 Changed prototype Z3950_records. For some functions, int parameters
2479 were changed to size_t.
2481 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2484 New MARC decode/display function, marc_display_exl, which properly rejects
2485 non-ISO2709 records. YAZ client uses it.
2487 --- 1.8.1 2001/10/29
2489 Fix bug: local attribute set wasn't set correctly in PQF strings.
2493 * Old Z39.50 codecs no longer supported.
2495 Added ZOOM C binding. See http://zoom.z3950.org/
2497 Renamed states for COMSTACKs to avoid confusion with events.
2499 Implemented cs_look and proper cs_rcvconnect.
2501 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2503 Configure detects POSIX threads on OpenBSD.
2505 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2506 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2508 When error is returned from present handler, non-surrogate diagnostic
2509 is returned in present response (and fetch handler is no longer called).
2511 * Minor adjustments to pquery parser (PQF). Token characters may be
2512 escaped by using backslash (C-style).
2514 PQF parser allows string attribute values to be specified. For @attr,
2515 non-numeric characters after the equal-sign are treated as strings
2516 (e.g. @attr 9=title).
2518 CCL trunction character may be defined (@truncation in file)
2520 * function zget_ExtendedServicesRequest sets waitAction to
2521 waitIfPossible (was wait).
2523 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2526 CCL operator names may be set in field definition files (CCL_bibset).
2527 See ccl/bib1 for an example.
2529 Fixes in ASN.1 compiler for C++ compatibility.
2531 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2532 and "op_or" to avoid conflict with C++.
2534 Fixed problem with GNU readline detection on Redhat 7.0.
2536 Added step-size for Scan backend handler.
2538 Fixed bug that made the frontend server crash when no attribute
2539 set was specified for scan.
2541 Front-end server automatically switches to original working directory
2542 when installed as an NT service. Previously -w had to be specified to
2545 Added extended attributes for retrieval module (data1), so that data1
2546 records carry d1_readXML/SGML attributes. d1_read also supports
2547 null-data rules ( <tag/>)
2549 On UNIX when POSIX threads are available, a separate library libyazthread
2550 is created. Programmers should link with that library and the yaz library
2551 when using threads. The reason for the split was that some applications
2552 on Linux, such as Apache, doesn't work well when using shared objects that
2555 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2556 (or any frontend server) in SSL mode by specifying ssl: followed by
2557 address. Only tested on UNIX.
2559 Added feature for CCL module. Virtual structure s=al or s=ol generates
2560 and-list and or-list respectively instead of phrase search.
2564 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2565 log_mask_str. This was done to avoid name conflicts with other libraries
2566 (such as other PHP extensions).
2568 Added raw OID member for preferred record syntax (request_format_raw)
2569 and returned record syntax (output_format_raw) for backend fetch method.
2571 Config file yaz-config now accepts options so that it returns specific
2572 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2574 Shared library support for UNIX using GNU libtool.
2576 * Modified backend interface. Request/Response struct's replaced by
2577 one read/write C struct. For example bend_fetchrequest and
2578 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2579 Every handler - even search has to be registered in bend_init
2580 handler. This means that the YAZ library no longer refers to
2581 external functions and it makes it possible to make the whole
2582 thing a single DLL/SO.
2584 Added Segment handler for backend server.
2586 Added Zmbol/Zebra administrative functions to YAZ client.
2588 Threaded frontend server on UNIX (when POSIX Threads are available).
2589 Starting the server with option -T enables multi-threading.
2593 Added configure option --enable-comp/disable-comp to control use
2594 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2595 located in sub directory asn.
2597 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2598 in ${exec_prefix}/bin along with the other programs yaz-client and
2601 GNU automake used to maintain makefiles.
2603 Added several OID's.
2605 Changed retrieval module so that we can load records with no abstract
2606 syntax defined. Tagpaths in these records are fully composed of string
2609 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2613 On UNIX, the generated makefile now supports a proper 'make install'.
2614 The prefix can be set via GNU configure to set the install location
2615 (default is /usr/local).
2617 * YAZ programs client and ztest were renamed to yaz-client and
2618 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2619 locations, such as /usr/bin,/usr/local/bin,etc.
2621 * YAZ Header files were moved from include to include/yaz. YAZ Header
2622 files are referred to as include <yaz/log.h> rather than <log.h>.
2623 The YAZ include path (-I ..) is therefore the same as before. Programmers
2624 should update their #include statements or use -Ipath/include/yaz
2625 instead. The main motivation for doing this change is that YAZ header files
2626 can be installed in "standard" locations /usr/include,/usr/local/include
2627 without introducing conflicts, since ALL YAZ header files are stored
2628 in subdirectory yaz (under /usr/include for example).
2630 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2631 rather than project/workspace files. We switched because project files
2632 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2635 Changed name of logging function, logf, to yaz_log, to prevent name
2636 clash with some math-log functions. The YAZ header log.h defines logf
2637 to yaz_log (#define) so there should be no incompatibilities by this
2640 Added bend_start/bend_stop handlers for server. These handler are
2641 called on start/stop of server. For windows they are called whenever
2642 a service is started/stopped.
2644 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2645 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2646 in util/yc.tcl. The auto-generated C code structures are, in a few
2647 cases, incompatible with the old decoders. There are differences in the
2648 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2649 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2650 The preprocessor variable ASN_COMPILED is defined when the compiled
2651 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2652 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2653 wish to use the old encoders/decoders you can specify --disable-yc
2656 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2657 version so that it supports both new - and old version of DB Update
2659 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2660 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2661 change. The name parameter can be set to 0 in which no name is specified
2662 for the construction. The macros odr_implicit and odr_explicit sets name
2663 parameter to zero for the construction involved. New macros
2664 odr_implicit_tag and odr_explicit_tag are similar to the others,
2665 except that a name parameter is added. For programmers' that don't use
2666 ODR they probably only need to change the call to z_APDU and z_External.
2668 Added access control facility by interfacing the TCP wrapper library.
2669 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2670 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2671 name of the daemon and enables the access control as specified in
2672 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2674 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2675 den Dool <H.M.vdnDool@kub.nl>.
2677 Added reference ID parameter to most functions in server API - refer
2678 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2680 Changed name of ccl library to libccl.a (was ccl.a).
2682 Fixed bug in decoder for Explain (Category TargetInfo).
2684 Added support for GNU readline in client. Thanks to Jacob Poulsen
2685 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2687 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2688 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2689 IMPLEMENTATION! This change was made to the development version before
2690 the ZIG decided to retract the amendment. If any users MUST be
2691 compatible with the original Update definition, PLEASE CONTACT US, and
2692 we will include a separate definition corresponding to the old Update
2693 ES. Note that because of the change to the ASN.1 of the
2694 TaskPackageRecordStructure we cannot define a single structure that
2695 will support both versions.
2697 * Added const modifier to buffer parameter for some ODR/BER encoding
2698 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2699 completeWAIS, odr_dumpBER.
2701 Fixed bug in client.c which caused a crash when a scanResponse didn't
2702 contain positionOfTerm.
2704 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2705 * will cause an error in a client if a non-YAZ target sends both a
2706 * list of Scan entries and non-surrogate diagnostics.
2708 Retrieval module enhancements. Tag sets may be typed in the reference
2709 to it. From the .abs-file the "tagset" directive takes a third optional
2710 integer type for the tag set referenced. From a .tag-file the "include"
2711 directive takes a third optional type as well. The old "type" directive
2712 in the tag set itself is still recognized but acts as the default type
2715 Backend interface change. Individual Scan terms returned from bend_scan
2716 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2717 in include/backend.h.
2719 Retrieval module enhancements. Multiple tag sets and attribute sets may
2720 be specified in abstract syntax specs. Revised the error/warning for
2721 logging messages reported by the retrieval module when reading the
2724 Object Identifier system (oid_..) changed. The API is backwards
2725 compatible but the oid-routines now allocates new OID's when needed.
2726 Raw OID's may be specified in oid_getvalbyname.
2728 YAZ now uses GNU configure to generate Makefile(s).
2730 * Minor changes in some of the member names of DeleteResultSetRequest and
2731 DeleteResultSetResponse. See include/proto.h.
2733 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2734 and added member 'languages' in TargetInfo (which was missing).
2736 Changed the way attribute sets are handled in the retrieval
2737 module. These are now cached, just like the abstract syntaxes
2740 Changed YAZ so that it links with compiled ASN.1.
2742 Added Explain-schema definitions and mapping routines. The following
2743 Explain categories have been implemented: AttributeDetails,
2744 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2746 Fixed minor bug in Windows version of Server Library.
2748 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2750 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2752 Added EXTERNAL: UNIverse Resource Report (non-standard).
2754 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2755 ENUMERATED and SET OF.
2757 * Added 'const' to some of the char pointer arguments for the
2758 functions, data1_read_node, data1_getelementbytagname,
2759 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2762 Fixed bug in data1_insert_taggeddata - the last_child member of
2763 parent wasn't initialised.
2765 * Changed data1_read_record and data1_read_node so that the supplied
2766 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2767 doesn't refer to any parts of the "SGML"-buffer.
2769 Fixed bug in server library (Windows version of statserv_remove).
2771 * Changed code so that it compiles as C++. The type definition
2772 of Odr_fun which is a member of Odr_arm was changed. The result is,
2773 that an explicit typecast is needed for the fun pointer when
2774 using Odr_arm - as in:
2775 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2777 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2779 Implemented the new structured date and time definition as approved
2780 by the ZIG. Added schemaId element to the specificTag in Espec-1
2781 (also approved at the last ZIG). Thanks to RVDM.
2783 Added some Object identifiers (RVDM).
2785 Changed the Update Extended Service (RVDM).
2787 Added command "refid" to client which specifies referenceId for
2788 the following requests.
2790 Implemented extended service handling for server. See ztest.c
2791 for an example as well as backend.h. New handlers are registerd
2792 in the Init handler.
2794 * Changed interface for sort in server.
2796 Added new members to statserv_options_block. It allows a server
2797 to read options from another source than just the command line. Thanks
2798 to Charles Woodfield.
2800 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2801 renamed to zboolean. Some C++ compilers complained about the name.
2803 Minor changes to gils.abs. Added index 's' (sort) on title
2804 and date/time-last-modified.
2806 --- 1.4pl2 1998/1/30
2808 Fixed bug in server library regarding inetd mode (-i). This bug
2809 was introduced by release 1.4.
2811 --- 1.4pl1 1998/1/29
2813 Added sort facility in client and backend server interface.
2815 Fixed problem with dependencies in Makefile(s).
2817 Fixed bugs for encoders/decoders of extended services and
2820 Implemented sub-tree feature for schemas. Sub-trees are
2821 referenced in *.abs-files. See explain.abs for an example
2822 of the use of this feature.
2824 Modified bib1.att; local attributes for ANY didn't include
2825 ANY itself (only affects use of the retrieval module).
2827 Fixed bug in plain SGML reader in function data1_read_node:
2828 tags with prefix "var" was incorrectly interpreted as variants.
2830 Added feature "sub-schemas" to enable references to - and definitions
2831 of - group of elements.
2833 * Removed member parent from type data1_element (in data1.h).
2835 Implemented function odr_nullval() that returns the value of
2838 * Removed member num_children from data1_node (in data1.h).
2840 Made NT service interface part of the server library. The
2841 function statserv_main uses the NT service when required and
2842 calls the statserv_start / statserv_close routines.
2844 Routine zget_SearchRequest and zget_PresentRequest fills
2845 resultSetName/Id member with "default" instead of "Default".
2847 Fixed memory leak in server. Request queue member wasn't freed.
2849 Fixed nmem_exit so that memory is freed.
2853 Revised the CCL parser utility to be thread safe.
2855 Added function, oid_ent_to_oid, to replace the function
2856 oid_getoidbyent, which is not thread safe.
2858 * Added nmem_init and nmem_exit to initialize and release
2859 NMEM resources. Function nmem_init should be called once in the
2860 initial thread before NMEM/ODR is used. statserv.c and client.c
2861 have been changed accordingly. The change was necessary to make
2862 NMEM thread safe. The NMEM memory pool is shared amongst threads
2863 in a process. Unix-based applications will still work fine without
2866 Added NT Services interface for the the Z39.50 (statserv) Server.
2867 Refer to the ztest.c source on the usage.
2869 Windows 95/NT port using MSVC5.0. Project files are included in the
2872 * Defined new 'global' handle for the retrieval (data1) system. The
2873 new handled, data1_handle, describes the state of the data1 system.
2874 This handle is passed as first argument to virtually all
2875 data1 related routines. The functions data1_create and data1_destroy
2876 creates and destroys a data1 handle respectively.
2878 Added ODR encode stream member to all backend request structures
2879 init, search, scan etc. This stream should be used to allocate all
2880 memory used for the response when thread safe operation is needed.
2882 Changed the comstack utility, cs_addstr, to be thread safe. The
2883 returned hostname string returned by the function is now part the
2886 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2887 function. The cs_straddr takes a COMSTACK handle as argument, so this
2888 function must be used after cs_create and before bind/connect.
2889 This function is thread safe.
2891 Moved test server to 'ztest' directory - generic server code still
2892 in 'server' directory.
2894 Made prefix query (pquery.c) utility thread safe.
2896 Added new function modifier YAZ_EXPORT to 'export' public DLL
2897 functions when using windows (see include/yconfig.h).
2899 Added definitions to the OID database (util/oid.c) (RVDM).
2901 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2903 Added call to ccl_rpn_delete in client program.
2905 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2906 release of RPN structure.
2908 Added support for C++, headers uses extern "C" for public definitions.
2909 With input from RVDM.
2911 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2912 Thanks to Ronald van der Meer (RVDM).
2914 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2916 Added support for private extensions to the OID database
2917 (oid_setprivateoids()). Thanks to RVDM.
2919 Added optional, physical ANY (key replication)
2921 Fixed null-reference problem in GRS-1 output filter.
2923 Proximity operator added to Prefix Query Format (PQF).
2925 In test client command "base" accepts multiple databases.
2927 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2931 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2933 Smallish bug-fixes in the new encoders/decoders (explain).
2935 Bug fixed in DeleteRequest.
2937 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2939 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2941 Added SOIF syntax (using private OID for now) to retrieval module and client.
2943 Added Update extended service.
2945 Added SearchResult-1 additional info structure.
2947 Added optional CCL (ISO8777) interpreter as separate module. Available
2950 --- 1.2 1996/6/10 (1st anniversary release)
2952 Added Summary record syntax. Lightly tested.
2954 Added OPAC record syntax. Untested.
2956 Added ResourceReport service encoders/decoders. Untested.
2958 Fixed bug in z_Unit - wrong tagging on unitSystem.
2960 Fixed bug in the DiagRecs decoder.
2962 Added options for max PDU size and session timeout to frontend-server.
2964 Added documentation of query-language parsers and other supporting utilities.
2966 [frontend-server] Added Attribute set to the bend_scanrequest API.
2968 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2969 surrogate diagnostics were generated.
2971 [retrieval] Allow multiple local values for attribute.
2973 [retrieval] Allow multiple attributes per element in .abs files. index type.
2975 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2977 --- 1.1pl2 1996/4/10
2979 Minor changes, mostly specific to Zebra's requirements (retrieval)
2983 Repaired bug in frontend server when running multiple listening
2984 endpoints in dynamic mode.
2986 z_External() now won't break if a known, ASN.1 value comes encapsulated
2987 in an octet-string. The value will pass through unmodified in an Odr_oct.
2989 Added a bit of code to the demo client to decode & display
2990 ASN.1-structured records represented in the octet-aligned branch of
2991 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2993 Added z_ext_getentbyref() to the ASN module. Doc updated.
2995 * Completed the SCAN definition in the ASN module. This may break SCAN
2996 code based on older YAZ-versions at compile-time. The fix is easy -
2999 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3000 under the SCAN definition. Remember to initialize this, server-people.
3002 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3003 that this does not extend to ODR and ASN.
3005 Comstack allows insertion of established socket (primarily for
3006 inetd-operation of servers). Doc updated.
3008 Front-end server can now start from the inetd in TCP mode. Doc
3011 --- 1.0pl4 1996/1/24
3015 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3016 the rank and record number.
3018 Adjustments to the frontend server.
3020 Fixed diagnostic BER dumper. It ignored the file argument.
3024 Various changes to retrieval module.
3026 Changed the union discriminators of the protocol files from enums to
3027 ints paired with #defines.
3029 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3032 *Changed operator in the RPN structure to 'roperator', again to avoid a
3035 Fixed problems in Explain decoders/encoders.
3037 --- 1.0pl2 1995/12/6
3039 Memory bug in log module fixed.
3041 --- 1.0pl1 1995/12/5
3043 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3045 Bug in Explain DatabaseInfo module fixed.
3047 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3051 The shift to v1.0 signals that we now consider the *core* functionality
3052 of YAZ reasonably stable (the core being more or less equivalent to
3053 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3054 tested (Explain not at all - though that will happen soonish).
3056 Minor changes to code to support Windows port.
3058 Various minor changes after we're getting to use GRS-1 & co. more.
3060 Added Espec-1 format.
3062 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3063 of the protocol and it cannot be selected when encoding (maps into 'string'
3064 when decoding). Needed to talk to some servers.
3066 Demo client can request simple element set names.
3068 Added Diagnostic Format encoders/decoders.
3070 Added simple Close handling to frontend server (no hooks for resource
3071 reporting yet), and demonstration client.
3073 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3075 --- 1.0b3 1995/08/24
3077 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3078 handled incorrectly when records were requested in the searchResponse. This
3079 will only affect you if you use the frontend-server.
3081 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3082 Test-client will ask for and print GRS1. Ztest will return dummy records
3085 Added Explain encoders/decoders to the service-level API. Untested.
3087 Added Extended Services: Item Order encoders and decoders to the Service-
3088 level API. Untested. We could use a recent copy of the pertinent bits
3089 of the ILL protocol to add those bits.
3091 Added diagnostic format 1 encoders/decoders to the service-level API.
3094 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3095 odr_cons.c, which causes a more correct output.
3097 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3098 was always set to 0 when no records were requested in the searchRequest.
3100 * Added better external-handling. This shouldn't harm old code that
3101 *encodes* externals. It can break code that looks for a
3102 'single-ASN1-type' representation, since those types that are known
3103 are now decoded immediately. Look at the SUTRS sample code in
3104 seshigh.c and client.c. Documentation updated.
3106 Handling of structured records in bend_fetchresponse. Length -1 marks
3107 structured record, type is deduced from format field.
3109 --- 1.0b2 1995/06/27
3110 Fairly quick maintenance release to add SUTRS support.
3112 Fixed handling of SUTRS records in the demonstration client.
3114 * Added format field to the bend_fetchrequest and bend_fetchresponce
3115 structures of the backend API (frontend server). When the record is
