3 Add two new SRU diagnostics:
4 236: Access to specified database denied
5 1015: Init/AC: Maximum number of simultaneous sessions for Userid
7 Document the very useful ZOOM-C option "apdulog".
9 CQL to RPN: term may be passed through verbatim. This is enabled with
10 truncation.cql . The assumption being that the term is already CQL.
14 record_conv: leader spec may be given for marc element.
15 The leader spec is given as attribute leaderspec for element marc.
16 For example to convert a MARC21 record from MARC-8 to UTF-8:
17 <marc inputformat="marc" outputformat="marc"
18 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
20 record_conv: allow user-XSLT params. For example:
21 <xslt stylesheet="MARC21slim2DC.xsl">
22 <param name="myparameter" value="myvalue"/>
23 <param name="otherparameter" value="othervalue"/>
26 record_conv: fix error handling for missing marc charsets.
28 CQL: fix extra terms in wrong order.
32 record_conv: modify new API for conversion types. The conversion types
33 may be passed in new functions yaz_record_conv_configure_t and
34 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
36 Avoid mixed statement/variable declare; fixes compilation with Visual
41 Add non-standard SRU diagnostic: 235: "Database does not exist".
42 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
43 Update SRU to Bib-1 diagnostic maps accordingly.
45 CCL: add two new diagnostics for unsupported masking. The new
46 diagnostics are: "Embedded truncation not supported" and
47 "Single charcacter mask not supported".
51 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
55 Build YAZ for Ubuntu Oneiric.
57 CCL: allow parantheses for proximity operands. For example CCL query
58 (a) % (b) is now allowed.
60 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
61 marked dead, rather then being destroyed. If not, the session memory is
62 being free'd before the search/scan handler is finished. Also destroy
63 'request' memory in request_release rather than in various places,
64 which resulted in leaks from time to time.
68 cql_sortby_to_sortkeys: honor sort prefix.
70 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
71 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
72 The rpn2cql family of functions now always returns quoted CQL terms.
74 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
78 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
79 sequence is treated as one. For example, &&a=b&&&c& is identical to
84 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
85 APDUs for a connection to a WRBUF.
89 Fix cql_sortby_to_sortkeys. Completely broken before.
91 Make CCL's @truncation work again.
95 New ZOOM connection setting: tproxy. It's like proxy, but does not
96 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
97 to set resolved address + port for a connection outside ZOOM itself.
99 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
101 --- 4.2.19 2011/11/07
103 Fix uninitialized variable in Solr spell support (could cause SEGV
104 for SRU response decoding).
106 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
107 back-end's addinfo through into the ZOOM response addinfo.
109 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
110 they are separated by a colon and a space rather than simply
113 --- 4.2.18 2011/10/28
115 Add support for Solr spell-checking/suggestions through ZOOM.
116 If a Solr target has been configured correctly for spelling-checking
117 and suggestions, these will now be returned on the ResultSet option
118 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
120 --- 4.2.17 2011/09/28
122 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
123 with a flag whether to substitute escape sequences or not.
125 --- 4.2.16 2011/09/22
127 Fix nmem_strsplit_escape to substitute escape char properly.
129 New option for zoomsh -e , which makes it abort on first error and
130 return process exit code to indicate success/failure.
132 YAZ options utility supports special option -- which makes all it treat
133 all following arguments as non-options.
135 --- 4.2.15 2011/09/16
137 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
138 searched if absolute filename is given.
140 Fix conv_xslt() error-reporting when stylesheet is not found.
141 (The value of fullpath is meaningless in this situation.)
143 --- 4.2.14 2011/09/07
145 Fix problem in CQL sort node creation: un-initialized memory.
147 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
148 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
149 CQL sortby depending on whether Type-1 or CQL is actually sent to the
152 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
153 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
155 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
156 will make it possible to use both single-character mask (#) and wildcard (?)
157 in CCL . Throw diagnostic for left truncation because that is not supported
160 --- 4.2.13 2011/09/01
162 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
163 cases using escapes (\-sequences) and masking.
165 PQF parse fix: A trailing backslash followed by end-of-string (\0)
166 would result in a read one byte beyond string.
168 rpn2ccl may use Z39.50 masking for terms (t=z).
170 ICU check fix. Don't include library -lCrun on Solaris, unless present.
172 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
173 not --cppflags (which seeems like an error in icu-config).
175 --- 4.2.12 2011/08/27 RPM package only
177 cql2ccl: fix conversion of terms: operator characters were not
180 --- 4.2.11 2011/08/25 RPM package only
182 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
183 CCL parser will map both # and ? to their regular expression
184 quivalents (. and .*).
186 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
187 of reserved CQL characters.
189 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
190 is, so that they are passed through.
192 --- 4.2.10 2011/08/24
194 ZOOM SRU mode: more aggressive re-connect.
196 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
197 made available as a utility function, declared in <yaz/logrpn.h>
199 rpn2cql_structure() supports proximity nodes (except that the Type-1
200 proximity node's "exclusion" binary is ignored, as there is no way to
201 express that in CQL). Fixes bug #4564.
205 Fix SEGV that could occur if set command of zoomsh was given without
206 value (2nd argument).
208 Fix SEGV that could occur if unsupported transport was given for
209 COMSTACK - say https (when SSL was unavailable).
211 Build yaz-url on Windows too.
215 New utility to get web content. Header is url.h. A command line tool
216 yaz-url is part of the distribution and packages.
218 Fixes for SSL COMSTACK (when gnutls is in use).
220 New functions yaz_base64{encode,decode}. Header is base64.h.
224 ZOOM C includes HTTP response buffer as additional info if it fails
225 to decode the SRU response.
227 Make wrbuf_json_puts available.
231 zoom: throw diagnostic for invalid value for option "sru". Before a
232 bad SRU request was sent.
234 Adding new utility wrbuf_vp_puts.
236 Add cclxmlconfig.obj to win/makefile. It was missing completely.
240 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
241 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
242 redirect was used at the same time.
244 MARC line mode decoding: be less picky about length given - first
245 5 digits of header that is.
247 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
249 Changes to decoding of SRU records: a record with recordPacking=xml is
250 modified with a new root element <yaz_record> if the recordData contains
251 multiple children elements. This is to make the record XML parseable
254 RPN to SOLR conversion: encode special characters.
256 Generic Frontend Server: fix uinitialized member, stepSize.
260 Fix a bug in SRU decoding of records.. The database records stored
261 had un-initialized memory, but it would only be seen with yaz_record_render
262 and type_spec="ext" .
264 Fix a bug in ccl_qual_dup introduced in 4.2.3.
268 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
272 Add new utilities to convert from CQL to CCL . These utilities have
273 prefix cql_to_ccl defined in cql.h.
275 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
276 lead to memory heap corruptions when ICU utilities were in use.
280 Make compilation work without Libxml2.
282 yaz-client: remove redundant blanks in display of searchResult-1 term
287 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
288 resulting CQL node (tree) in a new node CQL_NODE_SORT.
290 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
291 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
292 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
293 Note that the CQL sortby spec is only converted when the GFS is already
294 converting from CQL to RPN (cql2rpn element).
296 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
297 specify whether to collapse delimitors or not. The existing nmem_strsplit
298 do collapse (collapse parameter = 1).
300 Windows installer: For NSIS, set InstallDir depending on x86/x64.
302 Rename internal func yaz_use_attribute_create. While non-static, this
303 function is not declared in a public header.
307 Add -lCrun when linking with ICU on Solaris.
309 More quicks character set conversions for OPAC records.
313 fix problem with record_render: records were converted (character set
314 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
318 SRU: add methods for handling DADS SRU-proxy facets.
320 Separate OPAC record character set for ZOOM_record. yaz_record_render
321 allows a character set given as charset=from/opacfrom,to where 'from' is
322 the character set of a bibliographic record, 'opacfrom' is character set
323 of OPAC record and 'to' is the target character set.
327 yaz-client: show may XML format records. Command show followed by 'format'
328 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
331 src/stemmer.c: Avoid using unnamed union. It is not supported by some
334 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
337 Update yaz.spec to operate on both SLES11 / Centos 5.5.
339 RPM: Release includes 'indexdata' name. Use indexdata in release name so
340 this package can be distinguished from other vendors.
342 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
343 as determined by configure
345 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
347 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
348 returns no error and no record, the present request is considered
349 partial (only a subset of the records could be returned by backend), and
350 so it is appropriate to set Present Status to partial-4.
354 Move yaz-config man pages to section 1.
356 More documentation about SOLR.
358 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
359 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
360 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
361 peers on some Linux systems. However, in general that does not work
362 so YAZ can not rely on that to work. Debian changed behavior in this
363 respect from Debian lenny to Debian squeeze (still testing as of Oct
365 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
367 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
371 Fix yaz-config output: echo_source not set correctly by configure.
375 SOLR WebService support for yaz-client and ZOOM.
377 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
379 --- 4.0.12 2010/08/17
381 Z39.50 facet support. Facet specifications are passed for search in
382 other-information with ASN.1 as defined in facet.asn and OID
383 .10.1000.81.5 . Facets are expressed as an Attribute list as known
384 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
385 3 is limit (number of entries to get in response). yaz-ztest returns
386 dummy facets if a client asks for them.
388 --- 4.0.11 2010/07/09
390 CCL fixes: bug 2895 and bug 3539.
392 GR1-display: add comma in display - was removed by mistake in
395 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
397 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
399 --- 4.0.10 2010/06/18
401 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
402 result set from a connection. The result set will be on its own
403 thereafter; no operations on it will perform retrievals from a target.
404 Only cached copies are returned.
406 ZOOM C:fix case for HTTP servers responding with Connection:close.
407 Ensure that if there is a current task it is resumed (like fetching
408 more records in a result set) . Bug #3484.
410 PQF parser: use odr_atoi for Odr_int (not atoi)
412 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
413 values that contain any non-digits are treated as string attributes
414 (previously decoding only checked for leading character ([0-9]). PQF
415 encoding: attribute string values are not surrounded by double-quotes.
419 New utility for managing threads - thread_create.h.
421 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
422 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
423 but YAZ' implementation do.
425 Fixes for yaz_cond-functions on Windows 7.
427 DLL export more symbols.
429 zoomsh: show record do NOT render opac.
431 Remove *.la files from Debian and RPM packages.
435 Debian package libyaz-dev depends on libgnutls-dev again (was
436 removed in YAZ 4.0.6, but due to Libtool it is still needed
437 even though yaz-config do not list libgnutls libs).
439 ZOOM: Use only one WRBUF for returning string results for
440 ZOOM_resultset. Reduces memory usage for ZOOM in general.
442 ZOOM: ZOOM_connection do not use a shared pointer to
443 ZOOM_resultset after ZOOM_resultset is destructed by
444 user. Reverts to YAZ 4.0.4 behavior.
448 record-conv: fix problem with at least one XSL conversion -
449 due to probably incorrect usage of XML XSL documents.
453 Fix yaz-config for static mode and the use of SSL (gnutls).
457 Forward decl timeval struct in mutex.h and gettimeofday.h.
459 yaz-config: fix 'static' mode linking.
463 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
464 are wrappers for pthreads or Windows. For Windows these are put in
465 a separate DLL: yaz_cond4.
467 libyaz.la (whole source) is compiled with thread. If thread support
468 is enabled enabled, all source of YAZ is compiled with treading support.
469 This allows core utilities such as yaz_log to use thread facilities.
470 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
471 thread utilities. This commit moves mutex utilities (mutex.c) from
472 libyaz_server.la to libyaz.la.
474 yaz-json-parse displays leading text until error.
478 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
479 patch from Giannis Kosmas.
481 SRU: no longer URL encode SRU database. The URL for an SRU server is
482 a URL and such is alreeady encoded - at least when given with leading
483 http:// or https://. This reverts behavior to YAZ 3.0.50.
485 Support for new MARC XML notation TurboMARC which like MARCXML is a
486 complete representation of MARC/ISO2709.. This one, however, is more
487 compact and allows for faster processing with XSLT. TurboMARC can be
488 used in the marcdisp.h API, from the yaz-marcdump utility and from
491 yaz-ztest can be configured - via the database - to perform certain
492 delays when it performs operations search, present and single record
493 fetch. This allows testers to make yaz-ztest act as a real or even slow
494 Z39.50 server. Refer to the yaz-ztest man pages for details.
498 wrbuf_destroy allows NULL WRBUF passed to it.
500 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
502 Add ZOOM_connection_close.
504 No fixed size buffers for ZOOM shell - bug #3257.
506 tstodr: make it work on s390 platform.
508 New icu iterator-functions. The new icu_iter-functions makes it possible
509 to use ICU chains from many threads.
511 yaz-client: better syntax check for show command.
515 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
518 New simple local-file XML include facility which allows file glob-patterns.
519 Refer to yaz/xml_include.h.
521 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
524 ZOOM_record_get supports new parameter "format" which makes it format XML
527 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
528 JSONText in ECMA-262) is JSONValue, not JSONObject.
532 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
533 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
535 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
536 POSIX/Unix builds .so with major version 4.
538 Remove old LOG_-defines from log.h. They have been obsolete and
539 undefined by default for the last 5 years.
541 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
543 GFS: Remove socket (int *fd) from search_rr handler. The socket
544 descriptor ptr is a facility that allowed a search handler to supply
545 a socket which would serve as a callback - when search was complete.
546 This facility has now been in use for years.
548 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
549 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
550 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
551 returns 'const char *' rather than 'char *. The returned string is
552 read-only and should not be modified by applications. COMSTACK cs_close is
553 now a void function - it no longer returns int. No applications check for
554 the value and the implementations has always returned 0.
556 ZOOM: use size_t for scan hit counts and str size. Functions
557 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
558 occ (hit count) and len (string length) are now of type size_t pointer
559 rather than int pointer. This is to be able to represent large hit counts
560 and to also just to use the proper type for string length (strlen result).
562 New JSON parser. Refer to include/yaz/json.h .
564 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
565 Used to be int in some cases. Many wrbuf_-functions used to return an int
566 indicating some length.. These return values were never used. And so they
569 ODR: odr_malloc, odr_total now takes size_t for size.
571 clone_z_type: fix leak; occurred for encoding failures.
573 --- 3.0.52 2009/12/03
575 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
576 bug was introduced in 3.0.51.
578 --- 3.0.51 2009/12/02
580 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
582 tcpip comstack: fix leak for getaddrinfo.
584 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
585 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
586 Decoding of SRU "path" database is performed by private function
587 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
588 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
590 yaz-client: honor base command for SRU. Change when database setting
591 is applied for SRU and ensure it is kept when a connection is reset.
592 Change also the way errors are displayed or SRU (decoding of packages).
594 --- 3.0.50 2009/11/02
596 Add support for extra request / response data for SRU codecs and GFS.
597 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
598 for extra data response buffer and length. For the GFS, both request
599 and response data (XML) is carried in extra_args and extra_response_data
600 for the search handler. Patch by Ko van der Sloot.
602 ZOOM: For queries that cannot be converted to the specified rpnCharset,
603 ZOOM now returns a diagnostic on the client-side ('invalid query' /
604 10010). This fixes bug #2113.
606 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
607 cmdfile included a 'quit' command that would result in a memory violation.
609 --- 3.0.49 2009/10/01
611 Make a number of functions defined in xmlquery.c static. These have
612 never been declared in a public header file (yaz/xmlquery.h) and was
613 made public by mistake.
615 Improve speed of character conversions (iconv utilities). This makes
616 conversions from MARC-8 faster.
618 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
619 unless type desired is "raw". This will prevent type "xml" from
620 returning ISO2709 .. Which obviously can not be XML parsed.
622 Fix memory leak in ZOOM that would occur if option apdulog was used
623 on a re-used connection.
625 Frontend server logs HTTP requests.
627 Frontend server now sends Z39.50 close when it times out (sesssion has
628 been idle for too long). Versions 2.0.30 and earlier also sent close.
629 But due to a mistake this was disabled in all versions after that, i.e.
630 the server would just close the socket immediately.
632 yaz-client emits a better message when receiving an unrecognised
633 userInformationField.
635 Skip zero-length subfields when decoding ISO2709. This rare case happens
636 if a record has two FS characters in a sequence. Without this patch
637 there would be a reference beyond char array in using_code_len fragments
640 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
642 --- 3.0.48 2009/08/28
644 The show command offered by the zoomsh command now takes a 3d optional
645 parameter type which is what is passed to ZOOM_record. If the type
646 argument is omitted, "render" is used.
648 RPN to CQL conv may use USE string attributes (bug #2978).
650 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
652 --- 3.0.47 2009/07/08
654 Function yaz_xml2query allows a diagnostic element in the PQF XML
655 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
656 code and additional info respectively.
658 The BER BOOLEAN is now the integral type Odr_bool which still happens
659 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
660 typedef'd to Odr_int. This is still an integral 'int', but it may be
661 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
662 ASN-1 compiler as well as programs has been updated to use the new types.
664 --- 3.0.46 2009/06/08
666 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
667 only the bibliographic record was rendered. For type=opac, an OPAC
668 record is only returned if it is present.
670 iconv: small fix for encoding of advancegreek.
672 yaz-client: avoid double display of SRU/SRW records (bug #2798).
674 yaz-client: option auto_reconnect=on really reconnects.
676 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
678 server: avoid null ptr ref for for yaz_poll errors.
680 build: fix RPM build for RHEL 5.3.
682 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
684 --- 3.0.45 2009/03/31
686 Fixed bug #2709: TCP connect returns Invalid argument.
688 Fixed compilation for mingw.
690 Honor charset for raw records (ZOOM_record_get).
692 Fixed use of errno for threaded mode that was seen on Solaris 10.
694 Fixed argument passing with blanks in value for Windows Service.
696 Disable YAZ' own log rotate by default (no 1 GB limit).
697 The variable l_max_size which specifies the log file limit is set to 0
698 (DISABLED): This is due to the fact that YAZ is most often deployed using
699 logrotate. Also YAZ can not perform log rotate because of unsufficient
700 permissions (setuid).
702 --- 3.0.44 2009/02/17
704 List supported encodings in man page for yaz-iconv.
706 Fixed missing SSL libs for --libs output
708 Re-established OID record syntax application-xml. Nobody should use it
709 but we don't want to change soname because of this symbol being absent.
711 --- 3.0.42 2009/02/02
713 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
715 Added member named_result_sets for init handler struct for the GFS. This
716 allows a server to disable named result sets.
718 Removed OID record syntax application-xml.
720 Added support for rule-based transliterator for ICU wrapper of YAZ.
722 Fixed bug #1902: yaz-icu XML output.
724 Make YAZ checks Emacs friendly.
726 BITSTRING value shows value. Bug #2346.
728 ISO2709 decoding: skip control characters from indicator data.
730 Omit sort key by default in yaz-icu's output.
732 Allow combined single char options (again) for YAZ' options function.
734 Utility yaz-marcdump got option to display YAZ version (-V).
736 Allow YAZ to use ICU 3.4.
738 Added new ICU test case which illustrates removal of diacritics.
740 --- 3.0.41 2008/12/29
742 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
744 --- 3.0.40 2008/12/29
746 For configure, using option --without-xml2 also disables Libxslt/Libexslt
749 Fixed bug #2352: yaz-marcdump crashes for certain record.
751 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
753 Added support for Danmarc2 to UTF-8 conversion.
755 Added support for ISO5426 to UTF-8 conversion.
757 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
758 implementation version.
760 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
762 --- 3.0.38 2008/11/10
764 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
765 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
767 ZOOM C now interprets databaseName option for ZOOM connection as path
770 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
772 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
774 Dummy Libxml2 types no longer defined in headers of YAZ'.
776 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
779 --- 3.0.36 2008/09/26
781 Various ODR chapter fixes.
783 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
785 Added missing source for Windows compilation, mutex.c.
787 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
789 For SRU connections in ZOOM all records up to "count" are now fetched.
791 Fixed crash in generic frontend server (and yaz-ztest) which occurred
792 in Windows due to bad error handling for Libxml2.
794 Added facility for sending arbitrary records (ASN.1 any) using
795 ZOOM C's Extended service update. Patch by Sam Reynolds.
797 New options for ZOOM C's connection, logapdu which makes ZOOM log
800 --- 3.0.34 2008/06/18
802 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
804 --- 3.0.32 2008/06/12
806 Fixed memory violation that could occur when decoding UTF-8. This bug
807 was only present in 3.0.30 of YAZ.
809 --- 3.0.30 2008/06/06
811 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
812 GNU TLS is used by default (if found).
814 yaz-ztest returns OPAC records if a client asks for OPAC.
816 Improved speed of MARC-8 encoding.
818 Added support for lossy and loss-less MARC-8 encoding.
820 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
822 Added new Windows Service wrapper (sc).
824 yaz-client's itemorder command may now send a file.
826 Fixed yaz-marcdump to allow the use of NS prefix for record element.
828 Added new function yaz_log_xml_errors.
830 Allow (but warn) unknown XML attributes in MARCXML parsing.
832 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
834 The UTF-8 to MARC-8 conversion now uses a different set of characters
835 for Greek symbols. Bug #2120.
837 --- 3.0.26 2008/02/21
839 Added yaz_daemon (daemon.h).
841 Fixed bug #2068: pkg-config trouble
843 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
845 --- 3.0.24 2008/01/28
847 Document --with-xml2 option.
849 Added OPAC XML XSD (etc/opacxml.xsd).
851 Allow glob mask for name attribute in retrieval element for the
852 generic frontend server's retrieval facility.
854 Changed yaz_poll_poll to return yaz_poll_except for all returned events
855 except POLLIN/POLLOUT.
857 Fixed error handling in cs_listen. Bug #2037.
859 --- 3.0.22 2008/01/20
861 Fixed version in yaz/yaz-version.h.
863 Fixed bug #2027: Crash when closing connection.
865 Changed configure so that ICU support is only enabled if only ICU
866 and Libxml2 is available (because the ICU chain is XML based).
868 --- 3.0.20 2008/01/15
870 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
871 is built. Only this DLL depends on the ICU runtime.
873 yaz-ziffy is no longer part of YAZ. It is distributed separately by
874 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
876 Changed license of CCL module to 'Revised BSD'. After consultation with
877 remaining members of the original EUROPAGATE consortium, we are re-issuing
878 the CCL module without a separate license. The software was developed by
879 Index Data as part of a research project. The special license was included
880 to help feed usage information back to the project consortium to support
881 project evaluation. At this time, the project consortium has long-since
882 disbanded, and the majority of the original principals have retired. At the
883 same time, we have significantly modified the software during the following
884 years, to the point where very practically no original code remains. To
885 simplify re-use of the software, we have contacted those members of the
886 consortium who could be reached, and agreed to re-issue the module as a
887 proper part of the YAZ package.
889 Tcl scripts uses /usr/bin/tclsh as preferred shell.
891 CQL closer to being version 1.2 compliant. CQL also allows free-form
892 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
895 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
896 bug could make Extended services handling crash in the ZOOM layer. This
897 bug was only present in YAZ 3.0.18.
899 --- 3.0.18 2007/12/19
901 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
904 yaz-marcdump reads and writes collection wrapped records.
906 Handle OPAC for record conversion module.
908 Fixes for ICU wrapper.
910 Allow ICU libs to be controlled with --with-icu .
912 --- 3.0.16 2007/11/12
914 Added yaz_poll which is a wrapper for select/poll. When poll is available
915 and non-buggy, it is used, by yaz_poll . This allows more than 1024
916 sockets to be in use.
918 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
919 functionality through an XML based configuration (ICU chain). This system
920 is useful for search facilities such as Pazpar2 and Zebra that needs to
921 perform tokenization of indexed material. The ICU code in a separate
922 library libyaz3_icu.a.
924 Added HTTP tunnel facility for COMSTACK, bug #1752.
925 This is a facility that allows a Web proxy, such as squid, to tunnel
926 Z39.50 traffic. This facility is "transparent" to must applications
927 using YAZ. It's enabled by using pseudo transport connect: followed by
928 the proxy address, followed by command, then follwed by he regular
929 "virtual" addresss. For example,
930 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
932 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
934 --- 3.0.14 2007/09/21
936 Fixed bad memory reference in ZOOM_record - cuased by member not being
937 initialized. This was a problem only in YAZ 3.0.12.
939 Fixed bug in conversion from MARC to XML: Non-XML characters in control
940 fields were not removed.
942 Changed the way C code is generated from codetables.xml. Made a MARC-8
943 conversion trie for each characterSet section rather than codeTable.
944 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
945 of codetables.xml from Larry Dixson, LOC. Bug #1464.
947 --- 3.0.12 2007/09/12
949 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
950 from ZOOM_record_error).
952 ZOOM C function ZOOM_record_get returns record schema for type="schema".
954 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
956 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
958 Better SRW-to-Bib-1 diagnostic mapping.
960 ZOOM C and yaz-client announces SRU version 1.2 by default.
962 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
965 Fixed in yaz_sru_decode to allow other version than 1.1.
967 --- 3.0.10 2007/08/22
969 Added support for SRU scan for ZOOM.
971 Added support for the use of the older versions or Extended Service
972 Update in ZOOM. To faciliate this, an option "updateVersion" may be
973 set to the version , 1=first, 2=second, 3=third. The third version is
974 what ZOOM C has used so far. And that, obviously, is the default.
976 Added support for CCL queries in Z39.50 queries sent to the GFS (and
977 therefore in Zebra and in SimpleServer-based applications). The new
978 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
979 qualifier file used to transform incoming CCL queries into Type-1 RPN,
980 which is passed into the back-end search callback function.
982 Added support for HTTP Basic authentication in clients: the SRU/W
983 codec encodes the username/password elements of the PDU structure
984 appropriately, and these may be set using the "user" and "password"
985 options in ZOOM-C applications (the same options that are used for
986 Z39.50 authentication).
990 Fixed bug #1208: SSL appears to be broken in ZOOM.
992 Fixed bug #1206: Libxml2 include path weirdness.
994 Added oid_name_to_dotstring.
996 Allow elementSetName to be specified for ZOOM C record update.
998 Allow waitAction to be specified for ZOOM C based for Extended Services.
1000 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1001 syntax OID. Bug introduced in YAZ 3 series.
1003 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1005 --- 3.0.6 2007/06/06
1007 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1008 directory. yaz-client now reads commands from file given by option -f
1009 if specified; then tries to read .yazclientrc in current directory.
1010 Failing that, it reads .yazclientrc from user's home directory.
1012 Added support for correlationInfo Note and ID for Record Update via
1015 Added yaz-client command querycharset which specifies character set for
1016 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1017 (termListAndStartPoint).
1019 Charset ISO5428:1984 is an alias for ISO5428-1984.
1021 Implemented a way to perform scan in a result set using Z39.50. This
1022 is achieved by attaching the result set name in the characterInfo
1023 (type InternationalString) of OtherInformation in the Scan Request PDU.
1024 The result set is identified in the otherinformation by the new OID:
1025 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1026 This allows for scan in result set and faceted search . Zebra did some
1027 of this in the APT term using attribute type 8 and value being result
1028 set. Using the OtherInformation approach for this is cleaner and easier
1029 to work with in proxies and the like. This facility can be used in
1030 yaz-client using new command setscan which takes a result set as first
1031 argument, start position (APT) as second.
1033 Changed decoding of SRU XML packed records to deal with servers that
1034 have recordData with XML data with multiple root nodes. Also make
1035 comparison for recordPacking case insensitive. Again, one server
1036 returns "XML" where others return "xml".
1038 For SRU responses allow Content-Type application/xml as well as text/xml.
1040 --- 3.0.4 2007/05/21
1042 Fixed bug in character set conversion of BER strings. Bug introduced
1045 --- 3.0.2 2007/05/08
1047 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1049 For OID class, use oid_class consistently.
1051 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1054 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1055 character set for bibliographic information interchange". By Giannis Kosmas.
1057 Added documentation on new OID API.
1059 --- 3.0.0 2007/05/02
1061 Changes to generic frontend server interface: added new member
1062 'query_charset' for bend_initrequest structure. A backend init handler
1063 should set this member to its native character set for query terms.
1064 When defined, the frontend server logic will announce this character set
1065 to a client if the negotiationModel bit is set by the client. All server
1066 implementors are encouraged to specify this. If a backend server does not
1067 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1069 Added CCL utility to remove terms (stop words) from resulting RPN
1070 tree. This is handled by functions with prefix ccl_stop_words_ .
1072 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1073 terms in RPN queries.
1075 Clean-up the CCL API. Moved some internal structures from ccl.h to
1076 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1077 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1078 This is replaced by ccl_parser_find_str which takes a string instead.
1080 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1081 libyaz.la is the core of YAZ except the generic frontend server and
1082 does not depend on POSIX threads anymore. libyaz_server.la is the
1083 generic frontend server facilities and uses POSIX thread functionality
1084 if available. The libyaz.la no longer depends on POSIX threads because
1085 the number of global structures is limited. NMEM no longer re-uses blocks
1086 between threads ; it simply free's memory immediately but allocates in
1087 "large" chunks as usual. We don't expect any performance penalties
1088 because of this. The yaz_log system is still using a global log_level so
1089 caution must be taken when modifying it with yaz_log_init_.. +
1090 yaz_log_mask_str. This, however, should not cause any trouble because
1091 these functions are called during initialization of application code
1092 anyway. `yaz-config --libs server` returns libs for server applications;
1093 `yaz-config --libs` returns libs for non-server applications.
1095 New OID database - with public definitions in oid_db.h. Removed old OID
1096 database including the head oid.h and definitions such as enum oid_value
1097 and struct oident. The new OID database uses the same string names as
1098 before but the 'protocol' is gone. There are now only two representations
1099 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1100 converts from string to OID; functions with prefix yaz_oid_to_string
1101 converts the other way.
1103 Change to emit_term() in CQL-to-PQF query translation: when a term has
1104 the /regexp relation modifier, do not process it for leading and
1105 trailing "^" and "*", which have quite different meanings in regular
1108 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1109 write handlers no longer carries a 'last' parameter. This will make
1110 yaz_iconv flush "less" characters. A flush is performed by call to
1111 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1113 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1114 removed, because function yaz_query_to_wrbuf does the same.
1116 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1117 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1119 Deprecated MARC utility functions removed.
1121 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1124 Branch split: YAZ_2_1_55_branch
1126 --- 2.1.54 2007/03/16
1128 Fix to ZOOM-C so that transparent reconnection is properly handled on
1129 connections that are in asynchronous mode.
1131 Fixed compilation on OpenBSD 4.0.
1133 Large strings in GRS-1 records are now properly displayed in yaz-client.
1135 Added character conversion support for "advancegreek"; based on patch from
1138 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1139 sequence is met. Before the error was not set so it would be unknown.
1141 Adjust yaz-marcdump MARC reader so that it skips until record separator
1144 --- 2.1.52 2007/03/07
1146 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1147 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1148 fd_set structure used as a bitmask for the FDs to be selected on.
1150 Using ACX_PTHREAD macro to check for POSIX threads.
1152 Fixed have-vsnprintf check.
1154 --- 2.1.50 2007/02/23
1156 Fixes for configure on BSD. Bug #900.
1158 Added snprintf/vsnprintf wrappers for systems that don't have
1159 limits (heavens forbid).
1161 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1162 created before all previous tasks were completed and removed from the
1163 task queue, the new task could be removed by a mistake.
1165 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1167 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1169 Fixed bug #832: Problem with MARC/charset in yaz-client.
1171 Fixed bug #668: save command line history for yaz-client.
1173 Fixed bug #830: pkg-config support.
1175 --- 2.1.48 2007/01/23
1177 Extended ZOOM result set options with two options that may be read by
1178 a client: resultSetStatus and presentStatus with values as specified for
1180 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1182 Fixed bug #827: Using SSL fails on Debian etch.
1184 Fixed bug #826: Weird looking chars for set of MARC records.
1186 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1187 that is treated as an ItemOrder with itemRequest being an XML document
1188 external. The value of "doc" is the content.
1190 Extended the GFS search facility. New member of bend_search_rr
1191 'estimated_hit_count' signals that hits is known to be an estmate
1192 (higher or lower than real hit count). New member 'partial_resultset'
1193 signals that the search was partial (hit count is lower or equal than
1194 real hit count). For Z39.50, the information is stored in resultSetStatus
1195 member of SearchResponse APDU. For SRU, the information is signalled
1196 via SRU diagnostic 59: "Result set created with valid partial results
1199 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1201 --- 2.1.46 2007/01/13
1203 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1205 Added ZOOM_connection_peek_event.
1207 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1208 the following new functions:
1209 ZOOM_event_nonblock, ZOOM_connection_process,
1210 ZOOM_connection_get_{socket,mask,timeout},
1211 ZOOM_connection_fire_event_{timeout,socket}.
1212 The existing blocking event handler, ZOOM_event, is a wrapper for the
1213 + blocking ZOOM_event_sys_{poll,select}.
1215 Implemented function ccl_xml_config which parses XML version of CCL
1216 configuration (bug #798).
1218 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1220 Added timings utility (yaz/timing.h)
1222 --- 2.1.44 2007/01/03
1224 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1227 Fixed bug #779: Rotation of apdu.log fails.
1229 Fixed for character set conversions:
1230 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1231 Honor G1 set in MARC-8 decoding.
1233 --- 2.1.42 2006/12/17
1235 Fixed bug #775: char conversion does not handle Alternative UTF-8
1238 Implemented function yaz_marc_read_line which parses MARC line format
1239 records. There is a wealth of formats out there. So far, this function
1240 reads line records produced by yaz_marc_write_line.
1242 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1243 more generic and easier to remember(!) options: -i format and -o format
1244 which specifies input format and output format respectively - where
1245 format is one of "marc", "marcxml", "line", "marcxchange".
1247 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1248 does not print anything except warnings for records.
1250 For yaz-marcdump, added support for MARC split into files (-s) with a given
1253 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1254 spec, at http://www.loc.gov/standards/sru/record-update/
1255 This has changed the binary layout of the following structs:
1256 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1257 bend_update_rr . Patch by Ko van der Sloot.
1259 Added GFS utility function bend_assoc_is_alive which returns 1 if
1260 association is still alive (client is connected); 0 otherwise (client
1261 closed connection). This allows busy servers to stop working for
1264 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1265 been a separate piece of software. This version of ziffy has been modified
1266 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1268 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1270 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1271 Client code may now interrogate options such as "init_opt_sort" to
1272 find out whether the server claims to support various options.
1274 --- 2.1.40 2006/11/27
1276 Added utilities yaz_{set,get}_esn to set/get element set name from
1279 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1280 of YAZ and has been so since YAZ 2.1.10.
1282 Implemented ZOOM_record_error which returns error information for
1283 record (surrogate diagnostic).
1285 --- 2.1.38 2006/10/31
1287 Updates for SRU Update by Ko van der Sloot:
1288 1. Changed name from "operation" to "action"
1289 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1290 versions in the code, marked as 'backward compatible'.
1291 3. Added diagnostics for SRU Update.
1293 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1295 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1297 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1299 For GFS, fixed problem with SRU diagnostic 'First record position out of
1300 range' being issued for 0 hits.
1302 zoomtst10 part of Windows Build.
1304 --- 2.1.36 2006/10/13
1306 Implemented yaz_filepath_comp which splits a path into file path
1307 components (required by Zebra 2.0.3+).
1309 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1310 BSD inspired license until now so this should not have any real impact on
1311 anybody. See http://www.opensource.org/licenses/bsd-license.php
1313 Fixed bug #687: Missing log lines.
1315 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1318 Fixed bug #689: SRU diagnostics to be added.
1320 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1321 whether a connection is idle (no more work do do).
1323 --- 2.1.34 2006/10/04
1325 Change type of optval from long to int for invocation of setsockopt with
1326 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1328 Added support for specifying the max log file size for the Generic
1329 Frontend Server. The size is given with option -r.
1331 --- 2.1.32 2006/09/21
1333 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1335 --- 2.1.30 2006/09/17
1337 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1340 Fixed bug in Generic Frontend Server that could cause a server to stop
1341 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1343 For the generic frontend server, the maximum record size is used as maximum
1344 size of incoming packages (SRU + Z39.50). The value until was previously
1345 only used in Z39.50 Init negotiation and, later, in a session controlled
1346 sizes of records returned. This is controlled using -k option. It can be
1347 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1349 --- 2.1.28 2006/09/04
1351 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1354 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1356 New option for yaz-marcdump -lpos=value which allows setting a portion
1357 of MARC header to a certain value.
1359 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1361 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1362 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1364 --- 2.1.26 2006/08/15
1366 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1369 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1371 --- 2.1.24 2006/08/08
1373 Fixed MARC ISO2709 encoding routines to deal with character set
1376 Minor changes to GFS logging. Database included in search request log
1379 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1380 cached/multiple records.
1382 Shared libraries are built by default on Unix+configure.
1384 Changed cql2pqf transformation to use a different evaluation order. The
1385 new order is: always, relation, structure, position, truncation, index
1386 and relationModifier. Old order was: always, relation, relationModifier,
1387 structure, index, position, truncation. Note that the the latter ones
1388 override former ones for identical attributes.. The new scheme means that
1389 it is possible to override any existing attribute with a relationModifier.
1390 And also that it is possible to override everything for the index rule
1391 (except the ones listed in relationModifier). No order is perfect but this
1392 one, we believe, covers more real cases.. The "always" should have been
1393 called "default", since the attributes there can be overridden with all
1396 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1397 compilation phase, but also for yaz-config --cflags output. This allows
1398 us to have public headers with Libxml2 stuff in them . It should also,
1399 eventually, make Libxml2 checks redundant in packages using YAZ, such
1402 --- 2.1.22 2006/06/15
1404 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1405 stored in uri, message and details.. Previously diagnostics were stored
1406 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1407 compatibility.. but he's probably the only one affected, so.
1409 Added support for CCL, compiled on the client side, in ZOOM-C. This
1410 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1411 input; the resulting query objects can be used for for searching with
1412 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1414 YAZ' configure searches for OpenSSL by default.
1416 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1417 SL_CTX_use_certificate_file. See
1418 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1419 for more info. Thanks to Ko van der Sloot.
1421 --- 2.1.20 2006/06/02
1423 Bug #600: SRU GET, POST support for yaz-client. Introduced
1424 command 'sru' which selects method SOAP/GET/POST.
1426 Allow missingValueAction to be specified for the sortspec string -
1427 function yaz_sort_spec. By default, the missing value action is null.
1428 Use ! to specify "abort". Use = followed by stringvalue to specify default
1431 Ensured that Present-handler (if defined) is called in GFS before any call to
1432 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1433 searchRetrieve requests.
1435 Documentation for YAZ is now based on the Docbook XML/XSLT using
1436 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1437 is no longer depending on jade/openjade or docbook-to-man scripts.
1438 PDF is no longer part of the distribution - but can optionally be
1439 made using DSSSL/jadetex or FOP.
1441 Added retrieval handling support in Generic Frontend Server to support
1442 conversion between MARC/XML as well as XSLTtransforms. See
1443 etc/yazgfs.xml for an example.
1445 Added Authentication support to Generic Frontend Server in SRU
1446 mode. Authentication using HTTP Basic is supported, as is the use
1447 of 'x-username' and 'x-password' parameters in the request itself.
1449 Added support for a new character set MARC8s identical to MARC8 except
1450 that it converts combined characters to single Unicode characters in the
1451 Latin-1 range (when possible).
1453 --- 2.1.18 2006/04/24
1455 ASN.1 compiler 0.4: generates brief Doxygen file header for
1456 generated .h/.c files.
1458 Utility yaz_iconv now supports conversion to MARC-8.
1460 New facilities for the MARC module. The reading - and writing of
1461 content are separate methods for the yaz_marc_t handle. The following
1462 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1463 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1464 format). Write functions have prefix yaz_marc_write_.. The existing
1465 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1466 available. Removed support for OAI-MARC and simplexml (not the
1467 simplexml from PHP5).
1469 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1470 to be returned for this connection.
1472 --- 2.1.16 2006/03/31
1474 Allow multiple languages and charsets to be specified with
1475 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1476 negcharset iso-8859-1,utf-8
1478 Translation of proximity nodes from CQL into PQF now works.
1480 Moved to automake 1.8, 1.9.
1482 Added function yaz_log_set_handler which allows a log handler to be
1483 installed. This handler will be called for all log messages. Output
1484 to file is also produced; but that can be disabled by passing NULL
1485 fname to yaz_log_init_file.
1487 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1489 For SRW (including GFS), accept application/soap+xml as content-type
1492 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1493 produces NO stylesheet reference even if a default stylesheet is specified
1496 --- 2.1.14 2006/03/14
1498 Updated Windows package to include yazd.dll + yazd.lib for the
1499 Development component.
1501 If the environment variable YAZ_LOG is set, then it is used as a
1502 string indicating the default level of logging to use if not
1503 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1504 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1505 used as before. So, for example, to omit warnings from YAZ logging,
1506 export YAZ_LOG=-warn
1508 cql_transform() now map structure and other attributes before indexes,
1509 so that index-specific structures and other attributes can override
1510 defaults. So now a combination of mapping specifications such as:
1512 index.dc.date = 1=date-modified 4=5
1513 does the right thing.
1515 cql_transform() now also respects the "always" mapping specification,
1516 which establishes an initial set of attributes to be used for all
1517 terms except where overridden by more specific attributes associated
1518 with the index, relation or modifier.
1520 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1521 which mode to use; one of "post", "get" or "soap" (SRW, default).
1523 Fixes for yaz_iconv routines: changed trie-based character set conversions
1524 to use only non-negative values for bit fields due to Sun's C compiler not
1525 supporting negative values.
1527 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1528 sequences where not read correctly. Fix by Rustam Usmanov.
1530 Updated win/makefile to use options, settings which makes things
1531 compile with VS C 2005.
1533 --- 2.1.12 2006/02/01
1535 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1537 In ZOOM socket code, use select instead of poll on MacOSX.
1539 ZOOM-C now support client-side compilation of CQL into RPN that is
1540 sent to the server, enabling CQL to be used against all Z39.50
1541 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1542 ZOOM_query object, and submit it using ZOOM_connection_search().
1543 The CQL-to-RPN translation uses a configuration file, the name of
1544 which must be specified in the Connection's "cqlfile" option.
1546 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1547 function, which takes as its start-term parameter a ZOOM_query object
1548 (which may have had either CQL or RPN set into it).
1551 --- 2.1.10 2005/11/29
1553 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1554 GFS to support this as well. Backend handler, bend_srw_update, does the
1555 update work. Code contributed by Ko van der Sloot.
1557 Allow retrieval of Search Result-1 information in ZOOM by the use of
1558 options that are attached to a result set. ZOOM documentation updated
1561 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1562 UTF-8 conversion. Patch by Raj Patel.
1564 Added option -m to GFS to control formatting of timestamps in log file.
1566 Added 'exit' as synonym for 'quit' in yaz-client
1568 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1569 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1570 for the new members. Patch by Ko van der Sloot.
1572 Added support for SRU POST. It is supported for content-type
1573 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1575 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1576 Instead make the library libyaz.la multi-threaded. Threading as a whole
1577 can still be disabled by configure option --disable-threads. Previosly,
1578 with older GLIBCs there were problems with MT libs under Apache. This
1579 has now been fixed a long time ago.
1581 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1584 CQL module modified to be case insensitive for relations/indexes/operations.
1586 Fixed bug in CQL transform code: incorrect value relationModifieder
1589 Added 'show all' command for yaz-client which retrieves all results
1592 Added new yaz-client, xmles, which takes a (private) OID and
1593 a document to be sent as an extended service request.
1595 Describe new yaz-client commands wait_response and set_auto_wait.
1597 Increase TCP/IP listener backlog from 3 (which I am guessing was
1598 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1599 that the socket will queue as many incoming connections as it's able
1600 to handle ongoing connections. In other words, it will never now
1601 refuse a connection that it would be able to handle merely because
1602 it's not got around to accepting() enough of the pending connections
1603 yet. This is the behaviour anyway under Linux, where the listen()
1604 argument is ignored; but not under BSD and on systems such as
1605 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1606 YAZ-based servers should now be uniform across operating systems in
1609 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1610 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1611 This allows yaz-marcdump to read large MARC batches (>2 GB).
1613 Modified all YAZ source files - except the source which is auto-generated
1614 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1617 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1618 corresponding to the existing *_setl() function. These allow option
1619 values containing arbitrary valuues.
1621 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1622 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1623 except that it returns an indicator of whether or not the sort
1624 criterion was accepted (0 for OK, -1 for invalid).
1626 --- 2.1.8 2005/06/07
1628 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1629 MARC output rather than returning "new" buffer.
1631 yaz-client warns about unknown init options.
1633 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1635 --- 2.1.6 2005/05/24
1637 Added support for SRW sort in Generic Frontend Server. Patch
1638 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1639 sortKeys - or NULL if none is provided.
1641 Fixed bug #307: It was impossible to specify indefinite/no timeout
1642 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1645 Added support for multiple languages and charsets to be specified in
1646 ZOOM. Each charset/language is separated by a blank. If negotiation is
1647 in effect in init-response, Option
1648 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1649 Code based on patch by Vasiliy Osadchuk.
1651 Fixed bug #306: infinite recursion that occurred when calling
1652 yaz_log_level_init as the first call (before other log level or
1655 Fixed bug in scan handling in front end server: if preferred-Position-In-
1656 Response was non-present, a NULL pointer referece was performed.
1658 --- 2.1.4 2005/04/26
1660 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1661 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1662 now defined for all those error codes. So instead of putting 109 in
1663 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1664 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1666 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1669 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1671 Program yaz-client now exits and produces an error message if multiple
1672 Z39.50 servers are specified on the command line (none or one allowed
1675 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1678 --- 2.1.2 2005/03/16
1680 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1682 Fixed bug #272: Preserve spacing for CCL terms.
1684 --- 2.1.0 2005/03/14
1686 Added support for virtual hosts and multiple backend servers for
1687 the YAZ frontend server. The configution is XML based and
1688 support specificition of CQL to RPN mappings and explain information.
1689 See section "Virtual Hosts" in the YAZ manual.
1691 Extended OPAC display utility. OPAC display utility renders
1692 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1693 to supplement yaz_marc_decode_wrbuf.
1695 Fixed a bug in MARC decoder that could caused it to crash for some
1696 invalid MARC records. More diagnostics and warnings where added in
1697 XML output (warnings, etc are stored in comments).
1699 --- 2.0.34 2005/02/08
1701 Fixes for UNIX domain sockets. Bug #261.
1703 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1705 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1706 Added yaz_marc_subfield_str which defines subfield lead string which is
1707 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1708 yaz_marc_endline_str which defines end of fields string used in
1709 YAZ_MARC_LINE format. Default string is newline.
1711 Experimental support for MarcXChange. This format can be produced
1712 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1713 http://www.bs.dk/standards/MarcXchange.xsd
1715 Added yaz-client commands scansize that sets maximum number of
1716 entries to be returned by scan.
1718 --- 2.0.32 2005/01/11
1720 Added support for SRW scan in yaz-client and Generic Frontend Server.
1722 * Added whereInList member to SRW Scan Term.
1724 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1726 Fixed NMEM system to return aligned blocks on the smallest boundaries
1727 that are suitably aligned for all possible types on the particular
1728 architecture YAZ is being built for.
1730 --- 2.0.30 2005/01/04
1732 Fixed numerious warnings that was issued with newer versions of GCC.
1734 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1735 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1738 Make YAZ Generic Frontend Server slightly faster.
1740 Enhance (and reduce) logging for Generic Frontend Server.
1742 Revert YAZ log system so that it flushes every write operation
1743 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1745 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1746 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1747 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1748 will effectively disable old definitions.
1750 --- 2.0.28 2004/11/09
1752 Added yaz_log_time_format which specifies log format using
1755 Added yaz_log_module_level which returns mask for a module. Value
1756 is non-zero mask a if module is enabled; zero if disabled.
1758 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1759 in include/yaz/cql.h.
1761 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1763 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1765 Fixed bug #172: RPM builds does not enable SSL.
1767 Doxyfile.in part of dist. Doxyfile generated by configure.
1769 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1770 are given and the corresponding component does not exist.
1772 Extend CCL documentation in YAZ reference. Describe r=r.
1774 --- 2.0.26 2004/10/01
1776 Fixed MARC->MARCXML conversion to properly deal with
1777 fields, subfields, indicators having non-ASCII characters.
1779 Fixed MARC->MARCXML conversion so that ASCII control characters
1780 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1783 Added YAZ GFS support for conversion from Z39.50 surrogate
1784 diagnostics to SRW surrogate diagnostics.
1786 Bug fix: YAZ GFS did not return schema in explainResponse.
1788 --- 2.0.25 2004/09/30
1790 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1791 now converts recordSchema to elementSetName as well as schema URI.
1793 Fixed bug in COMSTACK that prevented HTTP request packages from being
1796 --- 2.0.24 2004/09/29
1798 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1799 does not require white-space before and after the dash in a range, e.g.
1800 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1803 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1804 due to new GCC removing "redundant" code.
1806 Added yaz-client commands scanpos and scanstep that sets preferred
1807 position and step-size for scan.
1809 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1811 Added CCL utility ccl_qual_buf which parses one or more CCL
1812 spec lines in a buffer.
1814 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1815 of name and value - ignoring empty lines and comments.
1817 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1819 Added odr_get_element_path which returns current element path for an
1820 ODR handle. This utility is useful in error handling or user-defined
1823 Added ODR_PRINT utility odr_set_stream which is is a more generic
1824 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1825 to a write function and pointer to close function. The close function - if
1826 non-NULL - will be called during odr_destroy.
1828 Fixed bug in CCL parser where truncation char was not removed from
1829 right side when truncation=both was in effect.
1831 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1834 --- 2.0.23 2004/08/11
1836 Fix buffer overrun in CQL parser when dealing with proximity (%).
1838 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1839 to UTF-8/UCS conversion is now only based on codetables.xml.
1841 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1843 --- 2.0.22 2004/08/06
1845 Add support for more "commit changes" in ZOOM (uses Extended Services).
1847 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1850 Yet another small fix for configure of SSL.
1852 --- 2.0.21 2004/05/14
1854 Fix SSL libs for configure when --with-openssl=DIR is given.
1856 --- 2.0.20 2004/05/10
1858 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1860 SSL comstack now uses yaz.pem certificate file on server side
1861 by default. Certificate filename can be configured by calling
1862 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1864 Fix bug regarding multiple calls to ZOOM_connection_connect.
1866 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1868 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1869 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1871 ZOOM now allows inspection of X509 peer certificate for verification.
1872 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1874 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1875 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1876 as "modular" but it simplifies things.
1878 Added cs_get_peer_certificate to that returns peer X509 PEM.
1880 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1881 NULL if SSL is unavailable.
1883 Documentation about MARC decoding tools.
1885 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1887 --- 2.0.19 2004/03/30
1889 Rename CHANGELOG to NEWS to follow GNU style packing.
1891 Fix bug with missing initialization of member in init_diagnostics.
1892 This bug affects threaded version of GFS server.
1894 --- 2.0.18 2004/03/20
1896 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1899 Ensure zlib.dll is packed with Windows install.
1901 --- 2.0.17 2004/03/17
1903 Fix encoding of xsd:string to use text instead of CDATA.
1905 Fix endless loop in CQL parser with unbalanced ".
1907 Use a more compact way to store MARC-8 conversion tables.
1909 --- 2.0.16 2004/03/16 Debian only
1911 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1914 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1919 --- 2.0.15 2004/03/01
1921 Another fix for decoding of XML packed records.
1923 --- 2.0.14 2004/02/25
1925 Fixes for Chunked encoding. White space not ignored after length spec.
1927 Update NS and use default NS for SRW diagnostic elements.
1929 --- 2.0.13 2004/02/23
1931 Implement ZOOM_resultset_cache_reset which resets record cache.
1933 Implement ZOOM_resultset_sort which sorts a result set.
1935 Implement chunked HTTP transfer.
1937 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1939 --- 2.0.12 2004/02/16
1941 Added member 'schema' to bend_explain_rr structure so that backend
1942 can specify explain record identifier. Defaults to Zeerex 2.0.
1944 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1946 --- 2.0.11 2004/02/16
1948 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1951 Added init command for yaz-client which sends "extra" init request.
1953 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1954 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1956 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1958 Make ZOOM error code for "invalid query".
1960 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1962 --- 2.0.10 2004/02/05
1964 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1967 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1969 Added option -p <file> to make Generic Frontend Server to write PID file.
1971 Added option -D to put Generic Frontend Server in background on its own.
1973 Make ZOOM C recognize option "password". If unset, "pass" is used
1974 (for backwards compatibility).
1976 Fixed a bug in Generic Frontend Server that could make it crash if a
1977 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1980 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1981 Must be issued before open, in order to be in effect.
1983 --- 2.0.9-6 2004/01/12 Debian/Windows
1985 Make the SRU server more picky WRT unknown params, etc.
1987 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1989 New YAZ client command, options, that sets Z39.50 options.
1991 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1992 options from a string of tokens (one token for each option bit).
1994 Update SRW diagnostic code messages.
1996 --- 2.0.9-5 2004/01/07 Debian/Windows
1998 Handle user defined stylesheet for SRW/SRU.
2000 --- 2.0.9-4 2004/01/06 Debian/Windows
2002 Fix bug in decoding of Content-Length.
2004 --- 2.0.9-3 2004/01/06 Debian/Windows
2006 Fix a bug with decoding of XML packed records.
2008 --- 2.0.9-2 2004/01/05 Debian only
2010 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2012 Fix bug in SRW/SRU diagnostics decoding.
2014 --- 2.0.9 2004/01/05
2016 Fixed bug in Generic Frontend Server which could drop records exceeding
2017 preferred message size. Reported and fixed by Irina Dijour.
2019 Fixed calculation of package size for structured records in Generic
2020 Frontend Server. Reported and fixed by Irina Dijour.
2022 Fixed namespace for SRW/SRU diagnostics.
2024 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2026 --- 2.0.8 2003/12/22
2028 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2029 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2032 CQL changes to reflect recent changes to the specification:
2033 * Documentation talks about context sets instead of index sets.
2034 * Documentation talks about indexes instead of qualifiers.
2035 * The CQL-to-PQF transformer's configuration file now uses
2036 "index.set.name = <attributes>" instead of the old form
2037 "qualifier.set.name = <attributes>". (Both forms are still
2038 understood but the latter is deprecated.)
2039 * CQL terms with no explicit index specified are now interpreted as
2040 cql.serverChoice instead of srw.serverChoice (which of course
2041 behaves exactly the same.)
2043 --- 2.0.7 2003/12/16
2045 MARC conversion can now generate ISO2709 output in another
2046 character set. yaz-marcdump uses this facility if you invoke it
2049 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2050 functions from there can be used from C++.
2052 --- 2.0.6 2003/12/04
2054 Frontend server now transfers memory from decoded packages to stream
2057 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2058 references to show up.
2060 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2061 the ZOOM Abstract API. The older names for the same options are still
2062 also supported for the benefit of old applications.
2064 ZOOM-C supports "implementationId" and "implementationVersion" options
2065 to go along with "implementationName". These allow the user code to
2066 specify identification strings to be sent to servers.
2067 Add OID for the new ExtLite attribute set.
2069 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2070 as requested/supplid by Ere Maijala <ere@atp.fi>
2072 For generic frontend server, reverse the order of
2073 "toolkit-supplied / application-supplied" strings sent as implementationId,
2074 Name and Version. Also, remove the spaces around the slash. This brings
2075 the GFS in line with the behaviour of ZOOM-C on the client side.
2077 Add function ZOOM_scanset_display_term.
2079 yaz-client shows scan displayTerm if present.
2081 Utility yaz-iconv is now installed by default along with the man page
2084 Extend configure check for OpenSSL to use pkg-config where available (such
2087 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2088 server to specify uid/gid/mask for socket using the format
2089 unix:[user=uid,][group=gid,][umask=mask,]file=path
2090 If file= is omitted the existing format is assumed, e.g.
2092 in which case the mask is 0666 (rw for everybody).
2094 Major restructure of YAZ source. All source in libyaz is in src directory.
2095 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2096 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2098 Added man page for utility yaz-marcdump (used to be called marcdump).
2099 yaz-marcdump is installed by 'make install'.
2101 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2102 of incoming package failed.
2104 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2106 Change prototype of odr_perror: add const to message string.
2108 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2110 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2111 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2112 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2113 DNS lookup. There should not be any compatibility problems with this
2114 assuming that blocking=1 or 0 is used.
2116 Fix bad reference in UNIX comstack in function cs_addrstr.
2118 Fix for compilation on AIX.
2120 The generic front-end server (server/seshigh.c) now supports returning
2121 Init diagnostics to the client in User-information-field, in
2122 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2125 --- 2.0.4 2003/09/04
2127 Allow any CQL relation (not just all,any,exact,scr).
2129 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2130 that features the same UI.
2132 Implemented command update0 in YAZ client which is equivalent to
2133 update but uses old of Ext Update ASN.1.
2135 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2136 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2137 Previously no OID was used for this info.
2139 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2140 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2141 returns 'malformed search term' otherwise.
2143 SortResponse member resultCount now set to NULL in sort handler of
2146 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2149 Add three new utility functions for translating OIDs between various
2150 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2151 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2152 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2153 char *oid_to_dotstring(const int *oid, char *oidbuf);
2154 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2156 Reverted modifications for ES Update definition for z_IU0Update
2157 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2158 is back to YAZ 2.0.2.
2160 String value attributes for CCL parser.
2162 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2163 which their FirstSearch server returns in Init responses, sometimes
2164 carrying useful diagnostic information when Init fails. This has the
2165 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2166 "z39.50/oclcui.asn", where its definition is somewhat different from
2167 what OCLC document on their web-site, as required to interoperate with
2170 Support for anonymous authentication in yaz-client. Use the command
2173 * Fix the OID of the Index Data-local "admin" Extended Service from
2174 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2175 the 1000, which indicates a locally-defined OID, was a mistake.
2177 --- 2.0.3 2003/06/20
2179 Fix CCL directive @case handling so that it affects string match for
2180 both CCL keywords and qualifiers.
2182 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2183 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2184 Decoder has been updated with ASN.1 changes as listed in
2185 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2186 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2187 z_IUUpdate, remains unchanged.
2189 ZOOM_record_get may now return a record in a specific character set.
2190 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2191 "from" is the character set of record as returned by target. "to" is
2192 the character set to be returned. If omitted, "to" is UTF-8.
2194 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2196 New ODR utility, odr_getelement, which returns name of element for
2197 which encoding/decoding failed.
2199 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2200 in cases where a required element was omitted.
2202 Bug fix: some MARC8 sequences were not converted.
2204 New ZOOM option "step" which specifies number of records to be
2205 retrieved in one chunk. Used in conjunction with "start" and "count".
2207 SRW support for yaz-client. Use scheme http: to use it, e.g.
2210 yaz-client no longer does (un)intelligent character set conversions
2211 by default. Can be enabled with charset and marc_charset commands.
2213 xmalloc trace fix for 64-bit systems such as DEC alpha.
2215 Solaris 2.6 compile fix.
2217 New function, cql_strerror() translates SRW error codes, as returned
2218 by cql_transform_error(), into human-readable English strings. Used
2219 in yaz-client diagnostics when appropriate.
2221 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2222 converts it into a type-1 query which is sent to the server. This
2223 makes CQL available for use with all Z-servers, as opposed to the tiny
2224 minority that can handle CQL queries themselves.
2226 --- 2.0.2 2003/04/28
2228 New Debian package layout similar to the Redhat Package layout.
2230 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2231 and search result respectively.
2233 --- 2.0.1 2003/04/25
2235 Redhat package is now several packages: libyaz (runtime libraries),
2236 libyaz-devel (development and documentation, and yaz (utility programs).
2237 Package spec file by Morten Bogeskov.
2239 New member 'schema' in struct bend_fetch_rr which the name of requested
2240 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2241 handler MAY set this to reflect the schema of the returned record.
2243 New member 'display_term' in struct scan_entry. GFS now sets member entries
2244 and allocates scan entries to be filled by user scan handler. In previous
2245 version, entries member was allocated by the scan handler. That still works,
2246 but the GFS will ignore member display_term - assuming it was NOT set by
2247 the handler. The fact that the GFS now allocates the entries both allows
2248 for new members and makes a scan handler easier to write.
2250 Fix CQL lex buffer overflow.
2252 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2253 SRU default recordPacking is string.
2255 SRU protocol support for frontend server.
2257 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2259 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2261 Added scan for the ZOOM shell (zoomsh).
2265 * String Identifers for Schemas (Amendment 5).
2266 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2267 Old definition for schema
2268 Odr_oid *schema; /* OPT */
2273 Z_InternationalString *uri;
2274 #define Z_Schema_oid 1
2275 #define Z_Schema_uri 2
2278 * resultCount parameter to Sort Response (Amendment 1).
2279 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2281 Support for SRW 1.0 over HTTP. This is an optional feature and
2282 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2285 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2286 on the same port. SRW SearchRetrieveRequests are mapped
2287 to bend_init,bend_search,bend_fetch,bend_close.
2289 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2291 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2292 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2294 ZOOM connections are SRW based if schem http is used for hostname
2295 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2296 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2298 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2299 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2300 distance=n, order=true/false, relation=le, prox unit=word. If
2301 n is omitted, distance 1 is used.
2303 Fixed problem with C compiler include path in wrong order.
2305 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2306 on Solaris. Patch from Ko van der Sloot.
2308 New MARC decode API. All new functions operate on a yaz_marc_t
2309 handle. The most important new functions are: yaz_marc_create,
2310 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2311 decode and destroy respectively. Decoder can produce formats
2312 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2313 include/yaz/marcdisp.h.
2315 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2316 to UTF-8, UCS-32, wchar_t or Latin-1.
2318 * Prototypes for yaz_iconv_-functions moved to separate header
2319 include/yaz/yaz-iconv.h.
2321 Make a few private functions 'static' in unix.c. This prevents
2322 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2324 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2325 are set when Init Response is received.
2327 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2328 but returns diagnostic set as well.
2330 New function yaz_strerror which is a portable wrapper for
2331 strerror/strerror_r/GetLastMessage.
2333 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2334 is returned for MARC. If type is "oai", then OAI MARC is returned.
2336 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2339 --- 1.9.2 2002/11/26
2341 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2343 Fix bad race conditions on SIGTERM and terminate gracefully in
2346 Move retrieval (data1) module to Zebra since nobody seems to be
2349 Add GRS-1 render for ZOOM using same format as yaz-client.
2351 --- 1.9.1 2002/10/05
2353 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2355 Fix broken ESpec handling in data1 module.
2357 SGML reader parses comments and makes them part of the data1 tree.
2359 Added several type casts so that YAZ compiles as C++ code.
2361 ZOOM didn't handle PDU encoding failures properly.
2363 Added more Bib-1 diagnostics (approved extensions).
2365 GNU configure: better check for iconv.
2367 More portable use of accept, getpeername. Check for socklen_t. Use
2368 int/size_t if socklen_t is not defined.
2372 PQF parser rejects bad queries - including those with extra
2373 characters in them. PQF parser used to silently ignore that.
2374 Cleaner API for PQF added, which allows you to get detailed
2375 error information for bad queries (see yaz/pquery.h).
2377 Fixed bug in ZOOM_record_get for type "database".
2379 Implemented mini iconv library supporting conversions between
2380 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2382 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2384 --- 1.8.9 2002/08/20
2386 Fixed ZOOM C record cache so that preferredRecordSyntax and
2387 elementSetName is used to check for already fetched records.
2389 --- 1.8.8 2002/08/02
2391 Added three members in bend_initrequest structure to facilitate
2392 character set negotiation.
2394 Fixed a bug in frontend server that could cause indefinite
2395 loops under rare conditions.
2397 Revised character set utilities (charneg.h) so that encoding
2398 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2400 For PQF, directive @term <type> sets term type for Scan/Search.
2401 Here <type> is general, string, numeric, null. The term type
2402 is inherited - just like @attr.
2404 New call odr_set_charset that sets character set conversion for
2405 international-strings on a ODR stream. Prototype is:
2406 int odr_set_charset(ODR o, const char *to, const char *from);
2407 The InternationalString is still represented as C string in YAZ
2408 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2409 won't). On the protocol level, you can use any encoding.
2411 Support for UNIX sockets in ZOOM.
2413 Solaris recv sometimes returns errno == ENOENT. It is treated as
2414 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2416 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2417 both client and server. Code by Morten Bogeskov.
2419 --- 1.8.7 2002/05/22
2421 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2422 that they can be used directly from Visual Basic. You must recompile
2423 your windows APP if you're using ZOOM.
2425 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2426 Commands "lang" and "charset" sets language and character set respectively.
2427 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2428 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2430 Attributes from multiple CCL fields may be OR'ed rather than merged
2431 using directive "@field or". Fields are still merged by default -
2432 equivalent to "@field merge".
2434 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2437 Fixed bug in zget for parameter ExtendedServicesResponse.
2441 --- 1.8.6 2002/03/25
2443 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2445 Client displays USR.1:SearchResult-1 (hits per term).
2447 Additional Search Info for search in Generic Frontend Server.
2449 Fixed CCL parsing of "field=s".
2451 WIN32 installer - using the excellent NSIS software from nullsoft.
2453 Fixed CCL parsing of "field = - <number>".
2455 Added function yaz_marc_decode that decodes MARC for line mode
2456 display or XML (similar to that used by JZKit).
2458 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2459 Z39.50. But ISO/ILL was, however.
2461 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2462 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2467 --- 1.8.5 2002/02/03
2469 New YAZ client features: Command completion and new commands:
2470 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2471 Code provided by Jacob Poulsen.
2473 New call oid_trav, that visits all registered OIDs via callback.
2475 Function ZOOM_record_get now returns const char pointer rather than
2476 void pointer. It saves a lot of type casts.
2478 For YAZ client, command "auth" now allows you to set authentication
2479 in IdPass style. It is enabled when three tokens are given - order
2480 is user, group and password.
2482 Fix memory leaks in MARC record handling for ZOOM.
2484 New option for YAZ client, -k <kilobytes> that sets
2485 maximum record size. Similar to -k option for generic frontend
2486 server and yaz-ztest.
2488 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2490 Prefix query parser reports "fail" when bad attribute set is given.
2492 Fix in MARC decoder. Proximity logging. Fix for attribute set
2493 in scan handler for server. Patches by Shigeru Ishida.
2495 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2498 Configure option --with-openssl=<dir> now works when a directory is
2499 specified. Patch provided by Morten Bogeskov.
2501 New option for YAZ client, -u <auth>, that sets authentication.
2503 ZOOM fix: error information was sometimes "missing", since error
2504 was cleared/reset too when it shouldn't.
2506 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2508 --- 1.8.4 2002/01/04
2510 Scan for ZOOM API. New object ZOOM_scanset. New functions
2511 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2512 ZOOM_scanset_destroy.
2514 New ZOOM function, ZOOM_connection_last_event, that returns type
2515 of last event (such as "receive data", "send data", "apdu received",
2518 New ZOOM option, schema, that specifies schema for retrieval.
2520 New CCL feature. Qualifiers can be aliases for one or more
2521 other qualifiers (if more than one is given, OR is used).
2523 ZOOM uses named result sets if target supports it.
2525 Two new YAZ client commands: . (dot, which sources a script of YAZ
2526 client commands), and ! (to execute shell command.). Implemented
2529 Working on Debian packages.
2531 --- 1.8.3 2001/11/19
2533 YAZ client enables named result sets only if target supports it.
2535 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2537 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2538 with key="host" to get same result.
2540 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2541 Function Z3950_resultset_record(s) returns references to records
2542 "owned" by resultset. To become owner use Z3950_record_clone.
2544 Function z_ext_record handles Extended Services. Thanks to
2547 --- 1.8.2 2001/11/12
2549 CCL Parser fix: ignore token comma when dealing with and-lists.
2551 Documentation updates for COMSTACK.
2553 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2554 Changed prototype Z3950_records. For some functions, int parameters
2555 were changed to size_t.
2557 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2560 New MARC decode/display function, marc_display_exl, which properly rejects
2561 non-ISO2709 records. YAZ client uses it.
2563 --- 1.8.1 2001/10/29
2565 Fix bug: local attribute set wasn't set correctly in PQF strings.
2569 * Old Z39.50 codecs no longer supported.
2571 Added ZOOM C binding. See http://zoom.z3950.org/
2573 Renamed states for COMSTACKs to avoid confusion with events.
2575 Implemented cs_look and proper cs_rcvconnect.
2577 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2579 Configure detects POSIX threads on OpenBSD.
2581 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2582 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2584 When error is returned from present handler, non-surrogate diagnostic
2585 is returned in present response (and fetch handler is no longer called).
2587 * Minor adjustments to pquery parser (PQF). Token characters may be
2588 escaped by using backslash (C-style).
2590 PQF parser allows string attribute values to be specified. For @attr,
2591 non-numeric characters after the equal-sign are treated as strings
2592 (e.g. @attr 9=title).
2594 CCL trunction character may be defined (@truncation in file)
2596 * function zget_ExtendedServicesRequest sets waitAction to
2597 waitIfPossible (was wait).
2599 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2602 CCL operator names may be set in field definition files (CCL_bibset).
2603 See ccl/bib1 for an example.
2605 Fixes in ASN.1 compiler for C++ compatibility.
2607 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2608 and "op_or" to avoid conflict with C++.
2610 Fixed problem with GNU readline detection on Redhat 7.0.
2612 Added step-size for Scan backend handler.
2614 Fixed bug that made the frontend server crash when no attribute
2615 set was specified for scan.
2617 Front-end server automatically switches to original working directory
2618 when installed as an NT service. Previously -w had to be specified to
2621 Added extended attributes for retrieval module (data1), so that data1
2622 records carry d1_readXML/SGML attributes. d1_read also supports
2623 null-data rules ( <tag/>)
2625 On UNIX when POSIX threads are available, a separate library libyazthread
2626 is created. Programmers should link with that library and the yaz library
2627 when using threads. The reason for the split was that some applications
2628 on Linux, such as Apache, doesn't work well when using shared objects that
2631 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2632 (or any frontend server) in SSL mode by specifying ssl: followed by
2633 address. Only tested on UNIX.
2635 Added feature for CCL module. Virtual structure s=al or s=ol generates
2636 and-list and or-list respectively instead of phrase search.
2640 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2641 log_mask_str. This was done to avoid name conflicts with other libraries
2642 (such as other PHP extensions).
2644 Added raw OID member for preferred record syntax (request_format_raw)
2645 and returned record syntax (output_format_raw) for backend fetch method.
2647 Config file yaz-config now accepts options so that it returns specific
2648 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2650 Shared library support for UNIX using GNU libtool.
2652 * Modified backend interface. Request/Response struct's replaced by
2653 one read/write C struct. For example bend_fetchrequest and
2654 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2655 Every handler - even search has to be registered in bend_init
2656 handler. This means that the YAZ library no longer refers to
2657 external functions and it makes it possible to make the whole
2658 thing a single DLL/SO.
2660 Added Segment handler for backend server.
2662 Added Zmbol/Zebra administrative functions to YAZ client.
2664 Threaded frontend server on UNIX (when POSIX Threads are available).
2665 Starting the server with option -T enables multi-threading.
2669 Added configure option --enable-comp/disable-comp to control use
2670 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2671 located in sub directory asn.
2673 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2674 in ${exec_prefix}/bin along with the other programs yaz-client and
2677 GNU automake used to maintain makefiles.
2679 Added several OID's.
2681 Changed retrieval module so that we can load records with no abstract
2682 syntax defined. Tagpaths in these records are fully composed of string
2685 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2689 On UNIX, the generated makefile now supports a proper 'make install'.
2690 The prefix can be set via GNU configure to set the install location
2691 (default is /usr/local).
2693 * YAZ programs client and ztest were renamed to yaz-client and
2694 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2695 locations, such as /usr/bin,/usr/local/bin,etc.
2697 * YAZ Header files were moved from include to include/yaz. YAZ Header
2698 files are referred to as include <yaz/log.h> rather than <log.h>.
2699 The YAZ include path (-I ..) is therefore the same as before. Programmers
2700 should update their #include statements or use -Ipath/include/yaz
2701 instead. The main motivation for doing this change is that YAZ header files
2702 can be installed in "standard" locations /usr/include,/usr/local/include
2703 without introducing conflicts, since ALL YAZ header files are stored
2704 in subdirectory yaz (under /usr/include for example).
2706 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2707 rather than project/workspace files. We switched because project files
2708 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2711 Changed name of logging function, logf, to yaz_log, to prevent name
2712 clash with some math-log functions. The YAZ header log.h defines logf
2713 to yaz_log (#define) so there should be no incompatibilities by this
2716 Added bend_start/bend_stop handlers for server. These handler are
2717 called on start/stop of server. For windows they are called whenever
2718 a service is started/stopped.
2720 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2721 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2722 in util/yc.tcl. The auto-generated C code structures are, in a few
2723 cases, incompatible with the old decoders. There are differences in the
2724 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2725 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2726 The preprocessor variable ASN_COMPILED is defined when the compiled
2727 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2728 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2729 wish to use the old encoders/decoders you can specify --disable-yc
2732 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2733 version so that it supports both new - and old version of DB Update
2735 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2736 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2737 change. The name parameter can be set to 0 in which no name is specified
2738 for the construction. The macros odr_implicit and odr_explicit sets name
2739 parameter to zero for the construction involved. New macros
2740 odr_implicit_tag and odr_explicit_tag are similar to the others,
2741 except that a name parameter is added. For programmers' that don't use
2742 ODR they probably only need to change the call to z_APDU and z_External.
2744 Added access control facility by interfacing the TCP wrapper library.
2745 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2746 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2747 name of the daemon and enables the access control as specified in
2748 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2750 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2751 den Dool <H.M.vdnDool@kub.nl>.
2753 Added reference ID parameter to most functions in server API - refer
2754 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2756 Changed name of ccl library to libccl.a (was ccl.a).
2758 Fixed bug in decoder for Explain (Category TargetInfo).
2760 Added support for GNU readline in client. Thanks to Jacob Poulsen
2761 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2763 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2764 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2765 IMPLEMENTATION! This change was made to the development version before
2766 the ZIG decided to retract the amendment. If any users MUST be
2767 compatible with the original Update definition, PLEASE CONTACT US, and
2768 we will include a separate definition corresponding to the old Update
2769 ES. Note that because of the change to the ASN.1 of the
2770 TaskPackageRecordStructure we cannot define a single structure that
2771 will support both versions.
2773 * Added const modifier to buffer parameter for some ODR/BER encoding
2774 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2775 completeWAIS, odr_dumpBER.
2777 Fixed bug in client.c which caused a crash when a scanResponse didn't
2778 contain positionOfTerm.
2780 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2781 * will cause an error in a client if a non-YAZ target sends both a
2782 * list of Scan entries and non-surrogate diagnostics.
2784 Retrieval module enhancements. Tag sets may be typed in the reference
2785 to it. From the .abs-file the "tagset" directive takes a third optional
2786 integer type for the tag set referenced. From a .tag-file the "include"
2787 directive takes a third optional type as well. The old "type" directive
2788 in the tag set itself is still recognized but acts as the default type
2791 Backend interface change. Individual Scan terms returned from bend_scan
2792 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2793 in include/backend.h.
2795 Retrieval module enhancements. Multiple tag sets and attribute sets may
2796 be specified in abstract syntax specs. Revised the error/warning for
2797 logging messages reported by the retrieval module when reading the
2800 Object Identifier system (oid_..) changed. The API is backwards
2801 compatible but the oid-routines now allocates new OID's when needed.
2802 Raw OID's may be specified in oid_getvalbyname.
2804 YAZ now uses GNU configure to generate Makefile(s).
2806 * Minor changes in some of the member names of DeleteResultSetRequest and
2807 DeleteResultSetResponse. See include/proto.h.
2809 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2810 and added member 'languages' in TargetInfo (which was missing).
2812 Changed the way attribute sets are handled in the retrieval
2813 module. These are now cached, just like the abstract syntaxes
2816 Changed YAZ so that it links with compiled ASN.1.
2818 Added Explain-schema definitions and mapping routines. The following
2819 Explain categories have been implemented: AttributeDetails,
2820 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2822 Fixed minor bug in Windows version of Server Library.
2824 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2826 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2828 Added EXTERNAL: UNIverse Resource Report (non-standard).
2830 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2831 ENUMERATED and SET OF.
2833 * Added 'const' to some of the char pointer arguments for the
2834 functions, data1_read_node, data1_getelementbytagname,
2835 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2838 Fixed bug in data1_insert_taggeddata - the last_child member of
2839 parent wasn't initialised.
2841 * Changed data1_read_record and data1_read_node so that the supplied
2842 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2843 doesn't refer to any parts of the "SGML"-buffer.
2845 Fixed bug in server library (Windows version of statserv_remove).
2847 * Changed code so that it compiles as C++. The type definition
2848 of Odr_fun which is a member of Odr_arm was changed. The result is,
2849 that an explicit typecast is needed for the fun pointer when
2850 using Odr_arm - as in:
2851 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2853 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2855 Implemented the new structured date and time definition as approved
2856 by the ZIG. Added schemaId element to the specificTag in Espec-1
2857 (also approved at the last ZIG). Thanks to RVDM.
2859 Added some Object identifiers (RVDM).
2861 Changed the Update Extended Service (RVDM).
2863 Added command "refid" to client which specifies referenceId for
2864 the following requests.
2866 Implemented extended service handling for server. See ztest.c
2867 for an example as well as backend.h. New handlers are registerd
2868 in the Init handler.
2870 * Changed interface for sort in server.
2872 Added new members to statserv_options_block. It allows a server
2873 to read options from another source than just the command line. Thanks
2874 to Charles Woodfield.
2876 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2877 renamed to zboolean. Some C++ compilers complained about the name.
2879 Minor changes to gils.abs. Added index 's' (sort) on title
2880 and date/time-last-modified.
2882 --- 1.4pl2 1998/1/30
2884 Fixed bug in server library regarding inetd mode (-i). This bug
2885 was introduced by release 1.4.
2887 --- 1.4pl1 1998/1/29
2889 Added sort facility in client and backend server interface.
2891 Fixed problem with dependencies in Makefile(s).
2893 Fixed bugs for encoders/decoders of extended services and
2896 Implemented sub-tree feature for schemas. Sub-trees are
2897 referenced in *.abs-files. See explain.abs for an example
2898 of the use of this feature.
2900 Modified bib1.att; local attributes for ANY didn't include
2901 ANY itself (only affects use of the retrieval module).
2903 Fixed bug in plain SGML reader in function data1_read_node:
2904 tags with prefix "var" was incorrectly interpreted as variants.
2906 Added feature "sub-schemas" to enable references to - and definitions
2907 of - group of elements.
2909 * Removed member parent from type data1_element (in data1.h).
2911 Implemented function odr_nullval() that returns the value of
2914 * Removed member num_children from data1_node (in data1.h).
2916 Made NT service interface part of the server library. The
2917 function statserv_main uses the NT service when required and
2918 calls the statserv_start / statserv_close routines.
2920 Routine zget_SearchRequest and zget_PresentRequest fills
2921 resultSetName/Id member with "default" instead of "Default".
2923 Fixed memory leak in server. Request queue member wasn't freed.
2925 Fixed nmem_exit so that memory is freed.
2929 Revised the CCL parser utility to be thread safe.
2931 Added function, oid_ent_to_oid, to replace the function
2932 oid_getoidbyent, which is not thread safe.
2934 * Added nmem_init and nmem_exit to initialize and release
2935 NMEM resources. Function nmem_init should be called once in the
2936 initial thread before NMEM/ODR is used. statserv.c and client.c
2937 have been changed accordingly. The change was necessary to make
2938 NMEM thread safe. The NMEM memory pool is shared amongst threads
2939 in a process. Unix-based applications will still work fine without
2942 Added NT Services interface for the the Z39.50 (statserv) Server.
2943 Refer to the ztest.c source on the usage.
2945 Windows 95/NT port using MSVC5.0. Project files are included in the
2948 * Defined new 'global' handle for the retrieval (data1) system. The
2949 new handled, data1_handle, describes the state of the data1 system.
2950 This handle is passed as first argument to virtually all
2951 data1 related routines. The functions data1_create and data1_destroy
2952 creates and destroys a data1 handle respectively.
2954 Added ODR encode stream member to all backend request structures
2955 init, search, scan etc. This stream should be used to allocate all
2956 memory used for the response when thread safe operation is needed.
2958 Changed the comstack utility, cs_addstr, to be thread safe. The
2959 returned hostname string returned by the function is now part the
2962 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2963 function. The cs_straddr takes a COMSTACK handle as argument, so this
2964 function must be used after cs_create and before bind/connect.
2965 This function is thread safe.
2967 Moved test server to 'ztest' directory - generic server code still
2968 in 'server' directory.
2970 Made prefix query (pquery.c) utility thread safe.
2972 Added new function modifier YAZ_EXPORT to 'export' public DLL
2973 functions when using windows (see include/yconfig.h).
2975 Added definitions to the OID database (util/oid.c) (RVDM).
2977 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2979 Added call to ccl_rpn_delete in client program.
2981 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2982 release of RPN structure.
2984 Added support for C++, headers uses extern "C" for public definitions.
2985 With input from RVDM.
2987 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2988 Thanks to Ronald van der Meer (RVDM).
2990 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2992 Added support for private extensions to the OID database
2993 (oid_setprivateoids()). Thanks to RVDM.
2995 Added optional, physical ANY (key replication)
2997 Fixed null-reference problem in GRS-1 output filter.
2999 Proximity operator added to Prefix Query Format (PQF).
3001 In test client command "base" accepts multiple databases.
3003 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3007 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3009 Smallish bug-fixes in the new encoders/decoders (explain).
3011 Bug fixed in DeleteRequest.
3013 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3015 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3017 Added SOIF syntax (using private OID for now) to retrieval module and client.
3019 Added Update extended service.
3021 Added SearchResult-1 additional info structure.
3023 Added optional CCL (ISO8777) interpreter as separate module. Available
3026 --- 1.2 1996/6/10 (1st anniversary release)
3028 Added Summary record syntax. Lightly tested.
3030 Added OPAC record syntax. Untested.
3032 Added ResourceReport service encoders/decoders. Untested.
3034 Fixed bug in z_Unit - wrong tagging on unitSystem.
3036 Fixed bug in the DiagRecs decoder.
3038 Added options for max PDU size and session timeout to frontend-server.
3040 Added documentation of query-language parsers and other supporting utilities.
3042 [frontend-server] Added Attribute set to the bend_scanrequest API.
3044 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3045 surrogate diagnostics were generated.
3047 [retrieval] Allow multiple local values for attribute.
3049 [retrieval] Allow multiple attributes per element in .abs files. index type.
3051 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3053 --- 1.1pl2 1996/4/10
3055 Minor changes, mostly specific to Zebra's requirements (retrieval)
3059 Repaired bug in frontend server when running multiple listening
3060 endpoints in dynamic mode.
3062 z_External() now won't break if a known, ASN.1 value comes encapsulated
3063 in an octet-string. The value will pass through unmodified in an Odr_oct.
3065 Added a bit of code to the demo client to decode & display
3066 ASN.1-structured records represented in the octet-aligned branch of
3067 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3069 Added z_ext_getentbyref() to the ASN module. Doc updated.
3071 * Completed the SCAN definition in the ASN module. This may break SCAN
3072 code based on older YAZ-versions at compile-time. The fix is easy -
3075 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3076 under the SCAN definition. Remember to initialize this, server-people.
3078 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3079 that this does not extend to ODR and ASN.
3081 Comstack allows insertion of established socket (primarily for
3082 inetd-operation of servers). Doc updated.
3084 Front-end server can now start from the inetd in TCP mode. Doc
3087 --- 1.0pl4 1996/1/24
3091 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3092 the rank and record number.
3094 Adjustments to the frontend server.
3096 Fixed diagnostic BER dumper. It ignored the file argument.
3100 Various changes to retrieval module.
3102 Changed the union discriminators of the protocol files from enums to
3103 ints paired with #defines.
3105 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3108 *Changed operator in the RPN structure to 'roperator', again to avoid a
3111 Fixed problems in Explain decoders/encoders.
3113 --- 1.0pl2 1995/12/6
3115 Memory bug in log module fixed.
3117 --- 1.0pl1 1995/12/5
3119 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3121 Bug in Explain DatabaseInfo module fixed.
3123 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3127 The shift to v1.0 signals that we now consider the *core* functionality
3128 of YAZ reasonably stable (the core being more or less equivalent to
3129 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3130 tested (Explain not at all - though that will happen soonish).
3132 Minor changes to code to support Windows port.
3134 Various minor changes after we're getting to use GRS-1 & co. more.
3136 Added Espec-1 format.
3138 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3139 of the protocol and it cannot be selected when encoding (maps into 'string'
3140 when decoding). Needed to talk to some servers.
3142 Demo client can request simple element set names.
3144 Added Diagnostic Format encoders/decoders.
3146 Added simple Close handling to frontend server (no hooks for resource
3147 reporting yet), and demonstration client.
3149 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3151 --- 1.0b3 1995/08/24
3153 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3154 handled incorrectly when records were requested in the searchResponse. This
3155 will only affect you if you use the frontend-server.
3157 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3158 Test-client will ask for and print GRS1. Ztest will return dummy records
3161 Added Explain encoders/decoders to the service-level API. Untested.
3163 Added Extended Services: Item Order encoders and decoders to the Service-
3164 level API. Untested. We could use a recent copy of the pertinent bits
3165 of the ILL protocol to add those bits.
3167 Added diagnostic format 1 encoders/decoders to the service-level API.
3170 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3171 odr_cons.c, which causes a more correct output.
3173 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3174 was always set to 0 when no records were requested in the searchRequest.
3176 * Added better external-handling. This shouldn't harm old code that
3177 *encodes* externals. It can break code that looks for a
3178 'single-ASN1-type' representation, since those types that are known
3179 are now decoded immediately. Look at the SUTRS sample code in
3180 seshigh.c and client.c. Documentation updated.
3182 Handling of structured records in bend_fetchresponse. Length -1 marks
3183 structured record, type is deduced from format field.
3185 --- 1.0b2 1995/06/27
3186 Fairly quick maintenance release to add SUTRS support.
3188 Fixed handling of SUTRS records in the demonstration client.
3190 * Added format field to the bend_fetchrequest and bend_fetchresponce
3191 structures of the backend API (frontend server). When the record is
3192 returned, the value of the format field is mapped to an OID. The
3193 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3194 of the record. The special value VAL_NONE in the bend_request means
3195 that no specific format was requested by the client. Documentation
3196 updated accordingly. Test server (ztest) will return a fixed dummy
3197 SUTRS record if your client requests SUTRS.
3199 Documentation updated accordingly.
3201 You can now set external libraries and RANLIB support in the top-level
3205 First public release.
