3 New ZOOM connection setting: tproxy. It's like proxy, but does not
4 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
5 to set resolved address + port for a connection outside ZOOM itself.
7 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
11 Fix uninitialized variable in Solr spell support (could cause SEGV
12 for SRU response decoding).
14 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
15 back-end's addinfo through into the ZOOM response addinfo.
17 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
18 they are separated by a colon and a space rather than simply
23 Add support for Solr spell-checking/suggestions through ZOOM.
24 If a Solr target has been configured correctly for spelling-checking
25 and suggestions, these will now be returned on the ResultSet option
26 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
30 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
31 with a flag whether to substitute escape sequences or not.
35 Fix nmem_strsplit_escape to substitute escape char properly.
37 New option for zoomsh -e , which makes it abort on first error and
38 return process exit code to indicate success/failure.
40 YAZ options utility supports special option -- which makes all it treat
41 all following arguments as non-options.
45 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
46 searched if absolute filename is given.
48 Fix conv_xslt() error-reporting when stylesheet is not found.
49 (The value of fullpath is meaningless in this situation.)
53 Fix problem in CQL sort node creation: un-initialized memory.
55 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
56 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
57 CQL sortby depending on whether Type-1 or CQL is actually sent to the
60 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
61 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
63 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
64 will make it possible to use both single-character mask (#) and wildcard (?)
65 in CCL . Throw diagnostic for left truncation because that is not supported
70 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
71 cases using escapes (\-sequences) and masking.
73 PQF parse fix: A trailing backslash followed by end-of-string (\0)
74 would result in a read one byte beyond string.
76 rpn2ccl may use Z39.50 masking for terms (t=z).
78 ICU check fix. Don't include library -lCrun on Solaris, unless present.
80 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
81 not --cppflags (which seeems like an error in icu-config).
83 -- 4.2.12 2011/08/27 RPM package only
85 cql2ccl: fix conversion of terms: operator characters were not
88 -- 4.2.11 2011/08/25 RPM package only
90 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
91 CCL parser will map both # and ? to their regular expression
92 quivalents (. and .*).
94 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
95 of reserved CQL characters.
97 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
98 is, so that they are passed through.
102 ZOOM SRU mode: more aggressive re-connect.
104 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
105 made available as a utility function, declared in <yaz/logrpn.h>
107 rpn2cql_structure() supports proximity nodes (except that the Type-1
108 proximity node's "exclusion" binary is ignored, as there is no way to
109 express that in CQL). Fixes bug #4564.
113 Fix SEGV that could occur if set command of zoomsh was given without
114 value (2nd argument).
116 Fix SEGV that could occur if unsupported transport was given for
117 COMSTACK - say https (when SSL was unavailable).
119 Build yaz-url on Windows too.
123 New utility to get web content. Header is url.h. A command line tool
124 yaz-url is part of the distribution and packages.
126 Fixes for SSL COMSTACK (when gnutls is in use).
128 New functions yaz_base64{encode,decode}. Header is base64.h.
132 ZOOM C includes HTTP response buffer as additional info if it fails
133 to decode the SRU response.
135 Make wrbuf_json_puts available.
139 zoom: throw diagnostic for invalid value for option "sru". Before a
140 bad SRU request was sent.
142 Adding new utility wrbuf_vp_puts.
144 Add cclxmlconfig.obj to win/makefile. It was missing completely.
148 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
149 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
150 redirect was used at the same time.
152 MARC line mode decoding: be less picky about length given - first
153 5 digits of header that is.
155 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
157 Changes to decoding of SRU records: a record with recordPacking=xml is
158 modified with a new root element <yaz_record> if the recordData contains
159 multiple children elements. This is to make the record XML parseable
162 RPN to SOLR conversion: encode special characters.
164 Generic Frontend Server: fix uinitialized member, stepSize.
168 Fix a bug in SRU decoding of records.. The database records stored
169 had un-initialized memory, but it would only be seen with yaz_record_render
170 and type_spec="ext" .
172 Fix a bug in ccl_qual_dup introduced in 4.2.3.
176 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
180 Add new utilities to convert from CQL to CCL . These utilities have
181 prefix cql_to_ccl defined in cql.h.
183 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
184 lead to memory heap corruptions when ICU utilities were in use.
188 Make compilation work without Libxml2.
190 yaz-client: remove redundant blanks in display of searchResult-1 term
195 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
196 resulting CQL node (tree) in a new node CQL_NODE_SORT.
198 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
199 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
200 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
201 Note that the CQL sortby spec is only converted when the GFS is already
202 converting from CQL to RPN (cql2rpn element).
204 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
205 specify whether to collapse delimitors or not. The existing nmem_strsplit
206 do collapse (collapse parameter = 1).
208 Windows installer: For NSIS, set InstallDir depending on x86/x64.
210 Rename internal func yaz_use_attribute_create. While non-static, this
211 function is not declared in a public header.
215 Add -lCrun when linking with ICU on Solaris.
217 More quicks character set conversions for OPAC records.
221 fix problem with record_render: records were converted (character set
222 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
226 SRU: add methods for handling DADS SRU-proxy facets.
228 Separate OPAC record character set for ZOOM_record. yaz_record_render
229 allows a character set given as charset=from/opacfrom,to where 'from' is
230 the character set of a bibliographic record, 'opacfrom' is character set
231 of OPAC record and 'to' is the target character set.
235 yaz-client: show may XML format records. Command show followed by 'format'
236 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
239 src/stemmer.c: Avoid using unnamed union. It is not supported by some
242 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
245 Update yaz.spec to operate on both SLES11 / Centos 5.5.
247 RPM: Release includes 'indexdata' name. Use indexdata in release name so
248 this package can be distinguished from other vendors.
250 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
251 as determined by configure
253 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
255 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
256 returns no error and no record, the present request is considered
257 partial (only a subset of the records could be returned by backend), and
258 so it is appropriate to set Present Status to partial-4.
262 Move yaz-config man pages to section 1.
264 More documentation about SOLR.
266 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
267 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
268 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
269 peers on some Linux systems. However, in general that does not work
270 so YAZ can not rely on that to work. Debian changed behavior in this
271 respect from Debian lenny to Debian squeeze (still testing as of Oct
273 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
275 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
279 Fix yaz-config output: echo_source not set correctly by configure.
283 SOLR WebService support for yaz-client and ZOOM.
285 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
287 --- 4.0.12 2010/08/17
289 Z39.50 facet support. Facet specifications are passed for search in
290 other-information with ASN.1 as defined in facet.asn and OID
291 .10.1000.81.5 . Facets are expressed as an Attribute list as known
292 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
293 3 is limit (number of entries to get in response). yaz-ztest returns
294 dummy facets if a client asks for them.
296 --- 4.0.11 2010/07/09
298 CCL fixes: bug 2895 and bug 3539.
300 GR1-display: add comma in display - was removed by mistake in
303 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
305 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
307 --- 4.0.10 2010/06/18
309 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
310 result set from a connection. The result set will be on its own
311 thereafter; no operations on it will perform retrievals from a target.
312 Only cached copies are returned.
314 ZOOM C:fix case for HTTP servers responding with Connection:close.
315 Ensure that if there is a current task it is resumed (like fetching
316 more records in a result set) . Bug #3484.
318 PQF parser: use odr_atoi for Odr_int (not atoi)
320 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
321 values that contain any non-digits are treated as string attributes
322 (previously decoding only checked for leading character ([0-9]). PQF
323 encoding: attribute string values are not surrounded by double-quotes.
327 New utility for managing threads - thread_create.h.
329 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
330 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
331 but YAZ' implementation do.
333 Fixes for yaz_cond-functions on Windows 7.
335 DLL export more symbols.
337 zoomsh: show record do NOT render opac.
339 Remove *.la files from Debian and RPM packages.
343 Debian package libyaz-dev depends on libgnutls-dev again (was
344 removed in YAZ 4.0.6, but due to Libtool it is still needed
345 even though yaz-config do not list libgnutls libs).
347 ZOOM: Use only one WRBUF for returning string results for
348 ZOOM_resultset. Reduces memory usage for ZOOM in general.
350 ZOOM: ZOOM_connection do not use a shared pointer to
351 ZOOM_resultset after ZOOM_resultset is destructed by
352 user. Reverts to YAZ 4.0.4 behavior.
356 record-conv: fix problem with at least one XSL conversion -
357 due to probably incorrect usage of XML XSL documents.
361 Fix yaz-config for static mode and the use of SSL (gnutls).
365 Forward decl timeval struct in mutex.h and gettimeofday.h.
367 yaz-config: fix 'static' mode linking.
371 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
372 are wrappers for pthreads or Windows. For Windows these are put in
373 a separate DLL: yaz_cond4.
375 libyaz.la (whole source) is compiled with thread. If thread support
376 is enabled enabled, all source of YAZ is compiled with treading support.
377 This allows core utilities such as yaz_log to use thread facilities.
378 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
379 thread utilities. This commit moves mutex utilities (mutex.c) from
380 libyaz_server.la to libyaz.la.
382 yaz-json-parse displays leading text until error.
386 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
387 patch from Giannis Kosmas.
389 SRU: no longer URL encode SRU database. The URL for an SRU server is
390 a URL and such is alreeady encoded - at least when given with leading
391 http:// or https://. This reverts behavior to YAZ 3.0.50.
393 Support for new MARC XML notation TurboMARC which like MARCXML is a
394 complete representation of MARC/ISO2709.. This one, however, is more
395 compact and allows for faster processing with XSLT. TurboMARC can be
396 used in the marcdisp.h API, from the yaz-marcdump utility and from
399 yaz-ztest can be configured - via the database - to perform certain
400 delays when it performs operations search, present and single record
401 fetch. This allows testers to make yaz-ztest act as a real or even slow
402 Z39.50 server. Refer to the yaz-ztest man pages for details.
406 wrbuf_destroy allows NULL WRBUF passed to it.
408 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
410 Add ZOOM_connection_close.
412 No fixed size buffers for ZOOM shell - bug #3257.
414 tstodr: make it work on s390 platform.
416 New icu iterator-functions. The new icu_iter-functions makes it possible
417 to use ICU chains from many threads.
419 yaz-client: better syntax check for show command.
423 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
426 New simple local-file XML include facility which allows file glob-patterns.
427 Refer to yaz/xml_include.h.
429 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
432 ZOOM_record_get supports new parameter "format" which makes it format XML
435 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
436 JSONText in ECMA-262) is JSONValue, not JSONObject.
440 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
441 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
443 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
444 POSIX/Unix builds .so with major version 4.
446 Remove old LOG_-defines from log.h. They have been obsolete and
447 undefined by default for the last 5 years.
449 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
451 GFS: Remove socket (int *fd) from search_rr handler. The socket
452 descriptor ptr is a facility that allowed a search handler to supply
453 a socket which would serve as a callback - when search was complete.
454 This facility has now been in use for years.
456 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
457 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
458 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
459 returns 'const char *' rather than 'char *. The returned string is
460 read-only and should not be modified by applications. COMSTACK cs_close is
461 now a void function - it no longer returns int. No applications check for
462 the value and the implementations has always returned 0.
464 ZOOM: use size_t for scan hit counts and str size. Functions
465 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
466 occ (hit count) and len (string length) are now of type size_t pointer
467 rather than int pointer. This is to be able to represent large hit counts
468 and to also just to use the proper type for string length (strlen result).
470 New JSON parser. Refer to include/yaz/json.h .
472 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
473 Used to be int in some cases. Many wrbuf_-functions used to return an int
474 indicating some length.. These return values were never used. And so they
477 ODR: odr_malloc, odr_total now takes size_t for size.
479 clone_z_type: fix leak; occurred for encoding failures.
481 --- 3.0.52 2009/12/03
483 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
484 bug was introduced in 3.0.51.
486 --- 3.0.51 2009/12/02
488 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
490 tcpip comstack: fix leak for getaddrinfo.
492 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
493 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
494 Decoding of SRU "path" database is performed by private function
495 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
496 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
498 yaz-client: honor base command for SRU. Change when database setting
499 is applied for SRU and ensure it is kept when a connection is reset.
500 Change also the way errors are displayed or SRU (decoding of packages).
502 --- 3.0.50 2009/11/02
504 Add support for extra request / response data for SRU codecs and GFS.
505 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
506 for extra data response buffer and length. For the GFS, both request
507 and response data (XML) is carried in extra_args and extra_response_data
508 for the search handler. Patch by Ko van der Sloot.
510 ZOOM: For queries that cannot be converted to the specified rpnCharset,
511 ZOOM now returns a diagnostic on the client-side ('invalid query' /
512 10010). This fixes bug #2113.
514 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
515 cmdfile included a 'quit' command that would result in a memory violation.
517 --- 3.0.49 2009/10/01
519 Make a number of functions defined in xmlquery.c static. These have
520 never been declared in a public header file (yaz/xmlquery.h) and was
521 made public by mistake.
523 Improve speed of character conversions (iconv utilities). This makes
524 conversions from MARC-8 faster.
526 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
527 unless type desired is "raw". This will prevent type "xml" from
528 returning ISO2709 .. Which obviously can not be XML parsed.
530 Fix memory leak in ZOOM that would occur if option apdulog was used
531 on a re-used connection.
533 Frontend server logs HTTP requests.
535 Frontend server now sends Z39.50 close when it times out (sesssion has
536 been idle for too long). Versions 2.0.30 and earlier also sent close.
537 But due to a mistake this was disabled in all versions after that, i.e.
538 the server would just close the socket immediately.
540 yaz-client emits a better message when receiving an unrecognised
541 userInformationField.
543 Skip zero-length subfields when decoding ISO2709. This rare case happens
544 if a record has two FS characters in a sequence. Without this patch
545 there would be a reference beyond char array in using_code_len fragments
548 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
550 --- 3.0.48 2009/08/28
552 The show command offered by the zoomsh command now takes a 3d optional
553 parameter type which is what is passed to ZOOM_record. If the type
554 argument is omitted, "render" is used.
556 RPN to CQL conv may use USE string attributes (bug #2978).
558 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
560 --- 3.0.47 2009/07/08
562 Function yaz_xml2query allows a diagnostic element in the PQF XML
563 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
564 code and additional info respectively.
566 The BER BOOLEAN is now the integral type Odr_bool which still happens
567 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
568 typedef'd to Odr_int. This is still an integral 'int', but it may be
569 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
570 ASN-1 compiler as well as programs has been updated to use the new types.
572 --- 3.0.46 2009/06/08
574 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
575 only the bibliographic record was rendered. For type=opac, an OPAC
576 record is only returned if it is present.
578 iconv: small fix for encoding of advancegreek.
580 yaz-client: avoid double display of SRU/SRW records (bug #2798).
582 yaz-client: option auto_reconnect=on really reconnects.
584 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
586 server: avoid null ptr ref for for yaz_poll errors.
588 build: fix RPM build for RHEL 5.3.
590 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
592 --- 3.0.45 2009/03/31
594 Fixed bug #2709: TCP connect returns Invalid argument.
596 Fixed compilation for mingw.
598 Honor charset for raw records (ZOOM_record_get).
600 Fixed use of errno for threaded mode that was seen on Solaris 10.
602 Fixed argument passing with blanks in value for Windows Service.
604 Disable YAZ' own log rotate by default (no 1 GB limit).
605 The variable l_max_size which specifies the log file limit is set to 0
606 (DISABLED): This is due to the fact that YAZ is most often deployed using
607 logrotate. Also YAZ can not perform log rotate because of unsufficient
608 permissions (setuid).
610 --- 3.0.44 2009/02/17
612 List supported encodings in man page for yaz-iconv.
614 Fixed missing SSL libs for --libs output
616 Re-established OID record syntax application-xml. Nobody should use it
617 but we don't want to change soname because of this symbol being absent.
619 --- 3.0.42 2009/02/02
621 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
623 Added member named_result_sets for init handler struct for the GFS. This
624 allows a server to disable named result sets.
626 Removed OID record syntax application-xml.
628 Added support for rule-based transliterator for ICU wrapper of YAZ.
630 Fixed bug #1902: yaz-icu XML output.
632 Make YAZ checks Emacs friendly.
634 BITSTRING value shows value. Bug #2346.
636 ISO2709 decoding: skip control characters from indicator data.
638 Omit sort key by default in yaz-icu's output.
640 Allow combined single char options (again) for YAZ' options function.
642 Utility yaz-marcdump got option to display YAZ version (-V).
644 Allow YAZ to use ICU 3.4.
646 Added new ICU test case which illustrates removal of diacritics.
648 --- 3.0.41 2008/12/29
650 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
652 --- 3.0.40 2008/12/29
654 For configure, using option --without-xml2 also disables Libxslt/Libexslt
657 Fixed bug #2352: yaz-marcdump crashes for certain record.
659 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
661 Added support for Danmarc2 to UTF-8 conversion.
663 Added support for ISO5426 to UTF-8 conversion.
665 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
666 implementation version.
668 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
670 --- 3.0.38 2008/11/10
672 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
673 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
675 ZOOM C now interprets databaseName option for ZOOM connection as path
678 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
680 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
682 Dummy Libxml2 types no longer defined in headers of YAZ'.
684 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
687 --- 3.0.36 2008/09/26
689 Various ODR chapter fixes.
691 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
693 Added missing source for Windows compilation, mutex.c.
695 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
697 For SRU connections in ZOOM all records up to "count" are now fetched.
699 Fixed crash in generic frontend server (and yaz-ztest) which occurred
700 in Windows due to bad error handling for Libxml2.
702 Added facility for sending arbitrary records (ASN.1 any) using
703 ZOOM C's Extended service update. Patch by Sam Reynolds.
705 New options for ZOOM C's connection, logapdu which makes ZOOM log
708 --- 3.0.34 2008/06/18
710 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
712 --- 3.0.32 2008/06/12
714 Fixed memory violation that could occur when decoding UTF-8. This bug
715 was only present in 3.0.30 of YAZ.
717 --- 3.0.30 2008/06/06
719 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
720 GNU TLS is used by default (if found).
722 yaz-ztest returns OPAC records if a client asks for OPAC.
724 Improved speed of MARC-8 encoding.
726 Added support for lossy and loss-less MARC-8 encoding.
728 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
730 Added new Windows Service wrapper (sc).
732 yaz-client's itemorder command may now send a file.
734 Fixed yaz-marcdump to allow the use of NS prefix for record element.
736 Added new function yaz_log_xml_errors.
738 Allow (but warn) unknown XML attributes in MARCXML parsing.
740 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
742 The UTF-8 to MARC-8 conversion now uses a different set of characters
743 for Greek symbols. Bug #2120.
745 --- 3.0.26 2008/02/21
747 Added yaz_daemon (daemon.h).
749 Fixed bug #2068: pkg-config trouble
751 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
753 --- 3.0.24 2008/01/28
755 Document --with-xml2 option.
757 Added OPAC XML XSD (etc/opacxml.xsd).
759 Allow glob mask for name attribute in retrieval element for the
760 generic frontend server's retrieval facility.
762 Changed yaz_poll_poll to return yaz_poll_except for all returned events
763 except POLLIN/POLLOUT.
765 Fixed error handling in cs_listen. Bug #2037.
767 --- 3.0.22 2008/01/20
769 Fixed version in yaz/yaz-version.h.
771 Fixed bug #2027: Crash when closing connection.
773 Changed configure so that ICU support is only enabled if only ICU
774 and Libxml2 is available (because the ICU chain is XML based).
776 --- 3.0.20 2008/01/15
778 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
779 is built. Only this DLL depends on the ICU runtime.
781 yaz-ziffy is no longer part of YAZ. It is distributed separately by
782 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
784 Changed license of CCL module to 'Revised BSD'. After consultation with
785 remaining members of the original EUROPAGATE consortium, we are re-issuing
786 the CCL module without a separate license. The software was developed by
787 Index Data as part of a research project. The special license was included
788 to help feed usage information back to the project consortium to support
789 project evaluation. At this time, the project consortium has long-since
790 disbanded, and the majority of the original principals have retired. At the
791 same time, we have significantly modified the software during the following
792 years, to the point where very practically no original code remains. To
793 simplify re-use of the software, we have contacted those members of the
794 consortium who could be reached, and agreed to re-issue the module as a
795 proper part of the YAZ package.
797 Tcl scripts uses /usr/bin/tclsh as preferred shell.
799 CQL closer to being version 1.2 compliant. CQL also allows free-form
800 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
803 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
804 bug could make Extended services handling crash in the ZOOM layer. This
805 bug was only present in YAZ 3.0.18.
807 --- 3.0.18 2007/12/19
809 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
812 yaz-marcdump reads and writes collection wrapped records.
814 Handle OPAC for record conversion module.
816 Fixes for ICU wrapper.
818 Allow ICU libs to be controlled with --with-icu .
820 --- 3.0.16 2007/11/12
822 Added yaz_poll which is a wrapper for select/poll. When poll is available
823 and non-buggy, it is used, by yaz_poll . This allows more than 1024
824 sockets to be in use.
826 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
827 functionality through an XML based configuration (ICU chain). This system
828 is useful for search facilities such as Pazpar2 and Zebra that needs to
829 perform tokenization of indexed material. The ICU code in a separate
830 library libyaz3_icu.a.
832 Added HTTP tunnel facility for COMSTACK, bug #1752.
833 This is a facility that allows a Web proxy, such as squid, to tunnel
834 Z39.50 traffic. This facility is "transparent" to must applications
835 using YAZ. It's enabled by using pseudo transport connect: followed by
836 the proxy address, followed by command, then follwed by he regular
837 "virtual" addresss. For example,
838 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
840 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
842 --- 3.0.14 2007/09/21
844 Fixed bad memory reference in ZOOM_record - cuased by member not being
845 initialized. This was a problem only in YAZ 3.0.12.
847 Fixed bug in conversion from MARC to XML: Non-XML characters in control
848 fields were not removed.
850 Changed the way C code is generated from codetables.xml. Made a MARC-8
851 conversion trie for each characterSet section rather than codeTable.
852 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
853 of codetables.xml from Larry Dixson, LOC. Bug #1464.
855 --- 3.0.12 2007/09/12
857 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
858 from ZOOM_record_error).
860 ZOOM C function ZOOM_record_get returns record schema for type="schema".
862 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
864 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
866 Better SRW-to-Bib-1 diagnostic mapping.
868 ZOOM C and yaz-client announces SRU version 1.2 by default.
870 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
873 Fixed in yaz_sru_decode to allow other version than 1.1.
875 --- 3.0.10 2007/08/22
877 Added support for SRU scan for ZOOM.
879 Added support for the use of the older versions or Extended Service
880 Update in ZOOM. To faciliate this, an option "updateVersion" may be
881 set to the version , 1=first, 2=second, 3=third. The third version is
882 what ZOOM C has used so far. And that, obviously, is the default.
884 Added support for CCL queries in Z39.50 queries sent to the GFS (and
885 therefore in Zebra and in SimpleServer-based applications). The new
886 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
887 qualifier file used to transform incoming CCL queries into Type-1 RPN,
888 which is passed into the back-end search callback function.
890 Added support for HTTP Basic authentication in clients: the SRU/W
891 codec encodes the username/password elements of the PDU structure
892 appropriately, and these may be set using the "user" and "password"
893 options in ZOOM-C applications (the same options that are used for
894 Z39.50 authentication).
898 Fixed bug #1208: SSL appears to be broken in ZOOM.
900 Fixed bug #1206: Libxml2 include path weirdness.
902 Added oid_name_to_dotstring.
904 Allow elementSetName to be specified for ZOOM C record update.
906 Allow waitAction to be specified for ZOOM C based for Extended Services.
908 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
909 syntax OID. Bug introduced in YAZ 3 series.
911 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
915 Fixed bug #1157: yaz-client does not read .yazclientrc from current
916 directory. yaz-client now reads commands from file given by option -f
917 if specified; then tries to read .yazclientrc in current directory.
918 Failing that, it reads .yazclientrc from user's home directory.
920 Added support for correlationInfo Note and ID for Record Update via
923 Added yaz-client command querycharset which specifies character set for
924 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
925 (termListAndStartPoint).
927 Charset ISO5428:1984 is an alias for ISO5428-1984.
929 Implemented a way to perform scan in a result set using Z39.50. This
930 is achieved by attaching the result set name in the characterInfo
931 (type InternationalString) of OtherInformation in the Scan Request PDU.
932 The result set is identified in the otherinformation by the new OID:
933 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
934 This allows for scan in result set and faceted search . Zebra did some
935 of this in the APT term using attribute type 8 and value being result
936 set. Using the OtherInformation approach for this is cleaner and easier
937 to work with in proxies and the like. This facility can be used in
938 yaz-client using new command setscan which takes a result set as first
939 argument, start position (APT) as second.
941 Changed decoding of SRU XML packed records to deal with servers that
942 have recordData with XML data with multiple root nodes. Also make
943 comparison for recordPacking case insensitive. Again, one server
944 returns "XML" where others return "xml".
946 For SRU responses allow Content-Type application/xml as well as text/xml.
950 Fixed bug in character set conversion of BER strings. Bug introduced
955 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
957 For OID class, use oid_class consistently.
959 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
962 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
963 character set for bibliographic information interchange". By Giannis Kosmas.
965 Added documentation on new OID API.
969 Changes to generic frontend server interface: added new member
970 'query_charset' for bend_initrequest structure. A backend init handler
971 should set this member to its native character set for query terms.
972 When defined, the frontend server logic will announce this character set
973 to a client if the negotiationModel bit is set by the client. All server
974 implementors are encouraged to specify this. If a backend server does not
975 specify this a warning is issued using yaz_log(YLOG_WARN,..).
977 Added CCL utility to remove terms (stop words) from resulting RPN
978 tree. This is handled by functions with prefix ccl_stop_words_ .
980 New ZOOM C option, "rpnCharset", which allows client-side conversion of
981 terms in RPN queries.
983 Clean-up the CCL API. Moved some internal structures from ccl.h to
984 private header cclp.h. Changed ccl_parser_create so that a Bibset must
985 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
986 This is replaced by ccl_parser_find_str which takes a string instead.
988 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
989 libyaz.la is the core of YAZ except the generic frontend server and
990 does not depend on POSIX threads anymore. libyaz_server.la is the
991 generic frontend server facilities and uses POSIX thread functionality
992 if available. The libyaz.la no longer depends on POSIX threads because
993 the number of global structures is limited. NMEM no longer re-uses blocks
994 between threads ; it simply free's memory immediately but allocates in
995 "large" chunks as usual. We don't expect any performance penalties
996 because of this. The yaz_log system is still using a global log_level so
997 caution must be taken when modifying it with yaz_log_init_.. +
998 yaz_log_mask_str. This, however, should not cause any trouble because
999 these functions are called during initialization of application code
1000 anyway. `yaz-config --libs server` returns libs for server applications;
1001 `yaz-config --libs` returns libs for non-server applications.
1003 New OID database - with public definitions in oid_db.h. Removed old OID
1004 database including the head oid.h and definitions such as enum oid_value
1005 and struct oident. The new OID database uses the same string names as
1006 before but the 'protocol' is gone. There are now only two representations
1007 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1008 converts from string to OID; functions with prefix yaz_oid_to_string
1009 converts the other way.
1011 Change to emit_term() in CQL-to-PQF query translation: when a term has
1012 the /regexp relation modifier, do not process it for leading and
1013 trailing "^" and "*", which have quite different meanings in regular
1016 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1017 write handlers no longer carries a 'last' parameter. This will make
1018 yaz_iconv flush "less" characters. A flush is performed by call to
1019 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1021 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1022 removed, because function yaz_query_to_wrbuf does the same.
1024 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1025 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1027 Deprecated MARC utility functions removed.
1029 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1032 Branch split: YAZ_2_1_55_branch
1034 --- 2.1.54 2007/03/16
1036 Fix to ZOOM-C so that transparent reconnection is properly handled on
1037 connections that are in asynchronous mode.
1039 Fixed compilation on OpenBSD 4.0.
1041 Large strings in GRS-1 records are now properly displayed in yaz-client.
1043 Added character conversion support for "advancegreek"; based on patch from
1046 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1047 sequence is met. Before the error was not set so it would be unknown.
1049 Adjust yaz-marcdump MARC reader so that it skips until record separator
1052 --- 2.1.52 2007/03/07
1054 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1055 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1056 fd_set structure used as a bitmask for the FDs to be selected on.
1058 Using ACX_PTHREAD macro to check for POSIX threads.
1060 Fixed have-vsnprintf check.
1062 --- 2.1.50 2007/02/23
1064 Fixes for configure on BSD. Bug #900.
1066 Added snprintf/vsnprintf wrappers for systems that don't have
1067 limits (heavens forbid).
1069 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1070 created before all previous tasks were completed and removed from the
1071 task queue, the new task could be removed by a mistake.
1073 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1075 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1077 Fixed bug #832: Problem with MARC/charset in yaz-client.
1079 Fixed bug #668: save command line history for yaz-client.
1081 Fixed bug #830: pkg-config support.
1083 --- 2.1.48 2007/01/23
1085 Extended ZOOM result set options with two options that may be read by
1086 a client: resultSetStatus and presentStatus with values as specified for
1088 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1090 Fixed bug #827: Using SSL fails on Debian etch.
1092 Fixed bug #826: Weird looking chars for set of MARC records.
1094 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1095 that is treated as an ItemOrder with itemRequest being an XML document
1096 external. The value of "doc" is the content.
1098 Extended the GFS search facility. New member of bend_search_rr
1099 'estimated_hit_count' signals that hits is known to be an estmate
1100 (higher or lower than real hit count). New member 'partial_resultset'
1101 signals that the search was partial (hit count is lower or equal than
1102 real hit count). For Z39.50, the information is stored in resultSetStatus
1103 member of SearchResponse APDU. For SRU, the information is signalled
1104 via SRU diagnostic 59: "Result set created with valid partial results
1107 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1109 --- 2.1.46 2007/01/13
1111 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1113 Added ZOOM_connection_peek_event.
1115 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1116 the following new functions:
1117 ZOOM_event_nonblock, ZOOM_connection_process,
1118 ZOOM_connection_get_{socket,mask,timeout},
1119 ZOOM_connection_fire_event_{timeout,socket}.
1120 The existing blocking event handler, ZOOM_event, is a wrapper for the
1121 + blocking ZOOM_event_sys_{poll,select}.
1123 Implemented function ccl_xml_config which parses XML version of CCL
1124 configuration (bug #798).
1126 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1128 Added timings utility (yaz/timing.h)
1130 --- 2.1.44 2007/01/03
1132 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1135 Fixed bug #779: Rotation of apdu.log fails.
1137 Fixed for character set conversions:
1138 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1139 Honor G1 set in MARC-8 decoding.
1141 --- 2.1.42 2006/12/17
1143 Fixed bug #775: char conversion does not handle Alternative UTF-8
1146 Implemented function yaz_marc_read_line which parses MARC line format
1147 records. There is a wealth of formats out there. So far, this function
1148 reads line records produced by yaz_marc_write_line.
1150 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1151 more generic and easier to remember(!) options: -i format and -o format
1152 which specifies input format and output format respectively - where
1153 format is one of "marc", "marcxml", "line", "marcxchange".
1155 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1156 does not print anything except warnings for records.
1158 For yaz-marcdump, added support for MARC split into files (-s) with a given
1161 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1162 spec, at http://www.loc.gov/standards/sru/record-update/
1163 This has changed the binary layout of the following structs:
1164 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1165 bend_update_rr . Patch by Ko van der Sloot.
1167 Added GFS utility function bend_assoc_is_alive which returns 1 if
1168 association is still alive (client is connected); 0 otherwise (client
1169 closed connection). This allows busy servers to stop working for
1172 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1173 been a separate piece of software. This version of ziffy has been modified
1174 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1176 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1178 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1179 Client code may now interrogate options such as "init_opt_sort" to
1180 find out whether the server claims to support various options.
1182 --- 2.1.40 2006/11/27
1184 Added utilities yaz_{set,get}_esn to set/get element set name from
1187 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1188 of YAZ and has been so since YAZ 2.1.10.
1190 Implemented ZOOM_record_error which returns error information for
1191 record (surrogate diagnostic).
1193 --- 2.1.38 2006/10/31
1195 Updates for SRU Update by Ko van der Sloot:
1196 1. Changed name from "operation" to "action"
1197 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1198 versions in the code, marked as 'backward compatible'.
1199 3. Added diagnostics for SRU Update.
1201 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1203 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1205 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1207 For GFS, fixed problem with SRU diagnostic 'First record position out of
1208 range' being issued for 0 hits.
1210 zoomtst10 part of Windows Build.
1212 --- 2.1.36 2006/10/13
1214 Implemented yaz_filepath_comp which splits a path into file path
1215 components (required by Zebra 2.0.3+).
1217 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1218 BSD inspired license until now so this should not have any real impact on
1219 anybody. See http://www.opensource.org/licenses/bsd-license.php
1221 Fixed bug #687: Missing log lines.
1223 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1226 Fixed bug #689: SRU diagnostics to be added.
1228 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1229 whether a connection is idle (no more work do do).
1231 --- 2.1.34 2006/10/04
1233 Change type of optval from long to int for invocation of setsockopt with
1234 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1236 Added support for specifying the max log file size for the Generic
1237 Frontend Server. The size is given with option -r.
1239 --- 2.1.32 2006/09/21
1241 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1243 --- 2.1.30 2006/09/17
1245 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1248 Fixed bug in Generic Frontend Server that could cause a server to stop
1249 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1251 For the generic frontend server, the maximum record size is used as maximum
1252 size of incoming packages (SRU + Z39.50). The value until was previously
1253 only used in Z39.50 Init negotiation and, later, in a session controlled
1254 sizes of records returned. This is controlled using -k option. It can be
1255 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1257 --- 2.1.28 2006/09/04
1259 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1262 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1264 New option for yaz-marcdump -lpos=value which allows setting a portion
1265 of MARC header to a certain value.
1267 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1269 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1270 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1272 --- 2.1.26 2006/08/15
1274 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1277 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1279 --- 2.1.24 2006/08/08
1281 Fixed MARC ISO2709 encoding routines to deal with character set
1284 Minor changes to GFS logging. Database included in search request log
1287 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1288 cached/multiple records.
1290 Shared libraries are built by default on Unix+configure.
1292 Changed cql2pqf transformation to use a different evaluation order. The
1293 new order is: always, relation, structure, position, truncation, index
1294 and relationModifier. Old order was: always, relation, relationModifier,
1295 structure, index, position, truncation. Note that the the latter ones
1296 override former ones for identical attributes.. The new scheme means that
1297 it is possible to override any existing attribute with a relationModifier.
1298 And also that it is possible to override everything for the index rule
1299 (except the ones listed in relationModifier). No order is perfect but this
1300 one, we believe, covers more real cases.. The "always" should have been
1301 called "default", since the attributes there can be overridden with all
1304 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1305 compilation phase, but also for yaz-config --cflags output. This allows
1306 us to have public headers with Libxml2 stuff in them . It should also,
1307 eventually, make Libxml2 checks redundant in packages using YAZ, such
1310 --- 2.1.22 2006/06/15
1312 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1313 stored in uri, message and details.. Previously diagnostics were stored
1314 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1315 compatibility.. but he's probably the only one affected, so.
1317 Added support for CCL, compiled on the client side, in ZOOM-C. This
1318 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1319 input; the resulting query objects can be used for for searching with
1320 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1322 YAZ' configure searches for OpenSSL by default.
1324 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1325 SL_CTX_use_certificate_file. See
1326 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1327 for more info. Thanks to Ko van der Sloot.
1329 --- 2.1.20 2006/06/02
1331 Bug #600: SRU GET, POST support for yaz-client. Introduced
1332 command 'sru' which selects method SOAP/GET/POST.
1334 Allow missingValueAction to be specified for the sortspec string -
1335 function yaz_sort_spec. By default, the missing value action is null.
1336 Use ! to specify "abort". Use = followed by stringvalue to specify default
1339 Ensured that Present-handler (if defined) is called in GFS before any call to
1340 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1341 searchRetrieve requests.
1343 Documentation for YAZ is now based on the Docbook XML/XSLT using
1344 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1345 is no longer depending on jade/openjade or docbook-to-man scripts.
1346 PDF is no longer part of the distribution - but can optionally be
1347 made using DSSSL/jadetex or FOP.
1349 Added retrieval handling support in Generic Frontend Server to support
1350 conversion between MARC/XML as well as XSLTtransforms. See
1351 etc/yazgfs.xml for an example.
1353 Added Authentication support to Generic Frontend Server in SRU
1354 mode. Authentication using HTTP Basic is supported, as is the use
1355 of 'x-username' and 'x-password' parameters in the request itself.
1357 Added support for a new character set MARC8s identical to MARC8 except
1358 that it converts combined characters to single Unicode characters in the
1359 Latin-1 range (when possible).
1361 --- 2.1.18 2006/04/24
1363 ASN.1 compiler 0.4: generates brief Doxygen file header for
1364 generated .h/.c files.
1366 Utility yaz_iconv now supports conversion to MARC-8.
1368 New facilities for the MARC module. The reading - and writing of
1369 content are separate methods for the yaz_marc_t handle. The following
1370 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1371 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1372 format). Write functions have prefix yaz_marc_write_.. The existing
1373 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1374 available. Removed support for OAI-MARC and simplexml (not the
1375 simplexml from PHP5).
1377 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1378 to be returned for this connection.
1380 --- 2.1.16 2006/03/31
1382 Allow multiple languages and charsets to be specified with
1383 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1384 negcharset iso-8859-1,utf-8
1386 Translation of proximity nodes from CQL into PQF now works.
1388 Moved to automake 1.8, 1.9.
1390 Added function yaz_log_set_handler which allows a log handler to be
1391 installed. This handler will be called for all log messages. Output
1392 to file is also produced; but that can be disabled by passing NULL
1393 fname to yaz_log_init_file.
1395 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1397 For SRW (including GFS), accept application/soap+xml as content-type
1400 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1401 produces NO stylesheet reference even if a default stylesheet is specified
1404 --- 2.1.14 2006/03/14
1406 Updated Windows package to include yazd.dll + yazd.lib for the
1407 Development component.
1409 If the environment variable YAZ_LOG is set, then it is used as a
1410 string indicating the default level of logging to use if not
1411 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1412 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1413 used as before. So, for example, to omit warnings from YAZ logging,
1414 export YAZ_LOG=-warn
1416 cql_transform() now map structure and other attributes before indexes,
1417 so that index-specific structures and other attributes can override
1418 defaults. So now a combination of mapping specifications such as:
1420 index.dc.date = 1=date-modified 4=5
1421 does the right thing.
1423 cql_transform() now also respects the "always" mapping specification,
1424 which establishes an initial set of attributes to be used for all
1425 terms except where overridden by more specific attributes associated
1426 with the index, relation or modifier.
1428 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1429 which mode to use; one of "post", "get" or "soap" (SRW, default).
1431 Fixes for yaz_iconv routines: changed trie-based character set conversions
1432 to use only non-negative values for bit fields due to Sun's C compiler not
1433 supporting negative values.
1435 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1436 sequences where not read correctly. Fix by Rustam Usmanov.
1438 Updated win/makefile to use options, settings which makes things
1439 compile with VS C 2005.
1441 --- 2.1.12 2006/02/01
1443 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1445 In ZOOM socket code, use select instead of poll on MacOSX.
1447 ZOOM-C now support client-side compilation of CQL into RPN that is
1448 sent to the server, enabling CQL to be used against all Z39.50
1449 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1450 ZOOM_query object, and submit it using ZOOM_connection_search().
1451 The CQL-to-RPN translation uses a configuration file, the name of
1452 which must be specified in the Connection's "cqlfile" option.
1454 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1455 function, which takes as its start-term parameter a ZOOM_query object
1456 (which may have had either CQL or RPN set into it).
1459 --- 2.1.10 2005/11/29
1461 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1462 GFS to support this as well. Backend handler, bend_srw_update, does the
1463 update work. Code contributed by Ko van der Sloot.
1465 Allow retrieval of Search Result-1 information in ZOOM by the use of
1466 options that are attached to a result set. ZOOM documentation updated
1469 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1470 UTF-8 conversion. Patch by Raj Patel.
1472 Added option -m to GFS to control formatting of timestamps in log file.
1474 Added 'exit' as synonym for 'quit' in yaz-client
1476 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1477 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1478 for the new members. Patch by Ko van der Sloot.
1480 Added support for SRU POST. It is supported for content-type
1481 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1483 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1484 Instead make the library libyaz.la multi-threaded. Threading as a whole
1485 can still be disabled by configure option --disable-threads. Previosly,
1486 with older GLIBCs there were problems with MT libs under Apache. This
1487 has now been fixed a long time ago.
1489 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1492 CQL module modified to be case insensitive for relations/indexes/operations.
1494 Fixed bug in CQL transform code: incorrect value relationModifieder
1497 Added 'show all' command for yaz-client which retrieves all results
1500 Added new yaz-client, xmles, which takes a (private) OID and
1501 a document to be sent as an extended service request.
1503 Describe new yaz-client commands wait_response and set_auto_wait.
1505 Increase TCP/IP listener backlog from 3 (which I am guessing was
1506 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1507 that the socket will queue as many incoming connections as it's able
1508 to handle ongoing connections. In other words, it will never now
1509 refuse a connection that it would be able to handle merely because
1510 it's not got around to accepting() enough of the pending connections
1511 yet. This is the behaviour anyway under Linux, where the listen()
1512 argument is ignored; but not under BSD and on systems such as
1513 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1514 YAZ-based servers should now be uniform across operating systems in
1517 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1518 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1519 This allows yaz-marcdump to read large MARC batches (>2 GB).
1521 Modified all YAZ source files - except the source which is auto-generated
1522 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1525 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1526 corresponding to the existing *_setl() function. These allow option
1527 values containing arbitrary valuues.
1529 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1530 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1531 except that it returns an indicator of whether or not the sort
1532 criterion was accepted (0 for OK, -1 for invalid).
1534 --- 2.1.8 2005/06/07
1536 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1537 MARC output rather than returning "new" buffer.
1539 yaz-client warns about unknown init options.
1541 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1543 --- 2.1.6 2005/05/24
1545 Added support for SRW sort in Generic Frontend Server. Patch
1546 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1547 sortKeys - or NULL if none is provided.
1549 Fixed bug #307: It was impossible to specify indefinite/no timeout
1550 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1553 Added support for multiple languages and charsets to be specified in
1554 ZOOM. Each charset/language is separated by a blank. If negotiation is
1555 in effect in init-response, Option
1556 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1557 Code based on patch by Vasiliy Osadchuk.
1559 Fixed bug #306: infinite recursion that occurred when calling
1560 yaz_log_level_init as the first call (before other log level or
1563 Fixed bug in scan handling in front end server: if preferred-Position-In-
1564 Response was non-present, a NULL pointer referece was performed.
1566 --- 2.1.4 2005/04/26
1568 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1569 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1570 now defined for all those error codes. So instead of putting 109 in
1571 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1572 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1574 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1577 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1579 Program yaz-client now exits and produces an error message if multiple
1580 Z39.50 servers are specified on the command line (none or one allowed
1583 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1586 --- 2.1.2 2005/03/16
1588 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1590 Fixed bug #272: Preserve spacing for CCL terms.
1592 --- 2.1.0 2005/03/14
1594 Added support for virtual hosts and multiple backend servers for
1595 the YAZ frontend server. The configution is XML based and
1596 support specificition of CQL to RPN mappings and explain information.
1597 See section "Virtual Hosts" in the YAZ manual.
1599 Extended OPAC display utility. OPAC display utility renders
1600 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1601 to supplement yaz_marc_decode_wrbuf.
1603 Fixed a bug in MARC decoder that could caused it to crash for some
1604 invalid MARC records. More diagnostics and warnings where added in
1605 XML output (warnings, etc are stored in comments).
1607 --- 2.0.34 2005/02/08
1609 Fixes for UNIX domain sockets. Bug #261.
1611 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1613 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1614 Added yaz_marc_subfield_str which defines subfield lead string which is
1615 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1616 yaz_marc_endline_str which defines end of fields string used in
1617 YAZ_MARC_LINE format. Default string is newline.
1619 Experimental support for MarcXChange. This format can be produced
1620 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1621 http://www.bs.dk/standards/MarcXchange.xsd
1623 Added yaz-client commands scansize that sets maximum number of
1624 entries to be returned by scan.
1626 --- 2.0.32 2005/01/11
1628 Added support for SRW scan in yaz-client and Generic Frontend Server.
1630 * Added whereInList member to SRW Scan Term.
1632 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1634 Fixed NMEM system to return aligned blocks on the smallest boundaries
1635 that are suitably aligned for all possible types on the particular
1636 architecture YAZ is being built for.
1638 --- 2.0.30 2005/01/04
1640 Fixed numerious warnings that was issued with newer versions of GCC.
1642 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1643 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1646 Make YAZ Generic Frontend Server slightly faster.
1648 Enhance (and reduce) logging for Generic Frontend Server.
1650 Revert YAZ log system so that it flushes every write operation
1651 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1653 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1654 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1655 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1656 will effectively disable old definitions.
1658 --- 2.0.28 2004/11/09
1660 Added yaz_log_time_format which specifies log format using
1663 Added yaz_log_module_level which returns mask for a module. Value
1664 is non-zero mask a if module is enabled; zero if disabled.
1666 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1667 in include/yaz/cql.h.
1669 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1671 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1673 Fixed bug #172: RPM builds does not enable SSL.
1675 Doxyfile.in part of dist. Doxyfile generated by configure.
1677 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1678 are given and the corresponding component does not exist.
1680 Extend CCL documentation in YAZ reference. Describe r=r.
1682 --- 2.0.26 2004/10/01
1684 Fixed MARC->MARCXML conversion to properly deal with
1685 fields, subfields, indicators having non-ASCII characters.
1687 Fixed MARC->MARCXML conversion so that ASCII control characters
1688 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1691 Added YAZ GFS support for conversion from Z39.50 surrogate
1692 diagnostics to SRW surrogate diagnostics.
1694 Bug fix: YAZ GFS did not return schema in explainResponse.
1696 --- 2.0.25 2004/09/30
1698 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1699 now converts recordSchema to elementSetName as well as schema URI.
1701 Fixed bug in COMSTACK that prevented HTTP request packages from being
1704 --- 2.0.24 2004/09/29
1706 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1707 does not require white-space before and after the dash in a range, e.g.
1708 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1711 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1712 due to new GCC removing "redundant" code.
1714 Added yaz-client commands scanpos and scanstep that sets preferred
1715 position and step-size for scan.
1717 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1719 Added CCL utility ccl_qual_buf which parses one or more CCL
1720 spec lines in a buffer.
1722 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1723 of name and value - ignoring empty lines and comments.
1725 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1727 Added odr_get_element_path which returns current element path for an
1728 ODR handle. This utility is useful in error handling or user-defined
1731 Added ODR_PRINT utility odr_set_stream which is is a more generic
1732 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1733 to a write function and pointer to close function. The close function - if
1734 non-NULL - will be called during odr_destroy.
1736 Fixed bug in CCL parser where truncation char was not removed from
1737 right side when truncation=both was in effect.
1739 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1742 --- 2.0.23 2004/08/11
1744 Fix buffer overrun in CQL parser when dealing with proximity (%).
1746 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1747 to UTF-8/UCS conversion is now only based on codetables.xml.
1749 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1751 --- 2.0.22 2004/08/06
1753 Add support for more "commit changes" in ZOOM (uses Extended Services).
1755 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1758 Yet another small fix for configure of SSL.
1760 --- 2.0.21 2004/05/14
1762 Fix SSL libs for configure when --with-openssl=DIR is given.
1764 --- 2.0.20 2004/05/10
1766 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1768 SSL comstack now uses yaz.pem certificate file on server side
1769 by default. Certificate filename can be configured by calling
1770 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1772 Fix bug regarding multiple calls to ZOOM_connection_connect.
1774 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1776 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1777 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1779 ZOOM now allows inspection of X509 peer certificate for verification.
1780 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1782 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1783 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1784 as "modular" but it simplifies things.
1786 Added cs_get_peer_certificate to that returns peer X509 PEM.
1788 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1789 NULL if SSL is unavailable.
1791 Documentation about MARC decoding tools.
1793 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1795 --- 2.0.19 2004/03/30
1797 Rename CHANGELOG to NEWS to follow GNU style packing.
1799 Fix bug with missing initialization of member in init_diagnostics.
1800 This bug affects threaded version of GFS server.
1802 --- 2.0.18 2004/03/20
1804 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1807 Ensure zlib.dll is packed with Windows install.
1809 --- 2.0.17 2004/03/17
1811 Fix encoding of xsd:string to use text instead of CDATA.
1813 Fix endless loop in CQL parser with unbalanced ".
1815 Use a more compact way to store MARC-8 conversion tables.
1817 --- 2.0.16 2004/03/16 Debian only
1819 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1822 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1827 --- 2.0.15 2004/03/01
1829 Another fix for decoding of XML packed records.
1831 --- 2.0.14 2004/02/25
1833 Fixes for Chunked encoding. White space not ignored after length spec.
1835 Update NS and use default NS for SRW diagnostic elements.
1837 --- 2.0.13 2004/02/23
1839 Implement ZOOM_resultset_cache_reset which resets record cache.
1841 Implement ZOOM_resultset_sort which sorts a result set.
1843 Implement chunked HTTP transfer.
1845 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1847 --- 2.0.12 2004/02/16
1849 Added member 'schema' to bend_explain_rr structure so that backend
1850 can specify explain record identifier. Defaults to Zeerex 2.0.
1852 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1854 --- 2.0.11 2004/02/16
1856 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1859 Added init command for yaz-client which sends "extra" init request.
1861 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1862 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1864 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1866 Make ZOOM error code for "invalid query".
1868 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1870 --- 2.0.10 2004/02/05
1872 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1875 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1877 Added option -p <file> to make Generic Frontend Server to write PID file.
1879 Added option -D to put Generic Frontend Server in background on its own.
1881 Make ZOOM C recognize option "password". If unset, "pass" is used
1882 (for backwards compatibility).
1884 Fixed a bug in Generic Frontend Server that could make it crash if a
1885 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1888 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1889 Must be issued before open, in order to be in effect.
1891 --- 2.0.9-6 2004/01/12 Debian/Windows
1893 Make the SRU server more picky WRT unknown params, etc.
1895 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1897 New YAZ client command, options, that sets Z39.50 options.
1899 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1900 options from a string of tokens (one token for each option bit).
1902 Update SRW diagnostic code messages.
1904 --- 2.0.9-5 2004/01/07 Debian/Windows
1906 Handle user defined stylesheet for SRW/SRU.
1908 --- 2.0.9-4 2004/01/06 Debian/Windows
1910 Fix bug in decoding of Content-Length.
1912 --- 2.0.9-3 2004/01/06 Debian/Windows
1914 Fix a bug with decoding of XML packed records.
1916 --- 2.0.9-2 2004/01/05 Debian only
1918 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1920 Fix bug in SRW/SRU diagnostics decoding.
1922 --- 2.0.9 2004/01/05
1924 Fixed bug in Generic Frontend Server which could drop records exceeding
1925 preferred message size. Reported and fixed by Irina Dijour.
1927 Fixed calculation of package size for structured records in Generic
1928 Frontend Server. Reported and fixed by Irina Dijour.
1930 Fixed namespace for SRW/SRU diagnostics.
1932 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1934 --- 2.0.8 2003/12/22
1936 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1937 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1940 CQL changes to reflect recent changes to the specification:
1941 * Documentation talks about context sets instead of index sets.
1942 * Documentation talks about indexes instead of qualifiers.
1943 * The CQL-to-PQF transformer's configuration file now uses
1944 "index.set.name = <attributes>" instead of the old form
1945 "qualifier.set.name = <attributes>". (Both forms are still
1946 understood but the latter is deprecated.)
1947 * CQL terms with no explicit index specified are now interpreted as
1948 cql.serverChoice instead of srw.serverChoice (which of course
1949 behaves exactly the same.)
1951 --- 2.0.7 2003/12/16
1953 MARC conversion can now generate ISO2709 output in another
1954 character set. yaz-marcdump uses this facility if you invoke it
1957 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1958 functions from there can be used from C++.
1960 --- 2.0.6 2003/12/04
1962 Frontend server now transfers memory from decoded packages to stream
1965 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1966 references to show up.
1968 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1969 the ZOOM Abstract API. The older names for the same options are still
1970 also supported for the benefit of old applications.
1972 ZOOM-C supports "implementationId" and "implementationVersion" options
1973 to go along with "implementationName". These allow the user code to
1974 specify identification strings to be sent to servers.
1975 Add OID for the new ExtLite attribute set.
1977 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1978 as requested/supplid by Ere Maijala <ere@atp.fi>
1980 For generic frontend server, reverse the order of
1981 "toolkit-supplied / application-supplied" strings sent as implementationId,
1982 Name and Version. Also, remove the spaces around the slash. This brings
1983 the GFS in line with the behaviour of ZOOM-C on the client side.
1985 Add function ZOOM_scanset_display_term.
1987 yaz-client shows scan displayTerm if present.
1989 Utility yaz-iconv is now installed by default along with the man page
1992 Extend configure check for OpenSSL to use pkg-config where available (such
1995 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1996 server to specify uid/gid/mask for socket using the format
1997 unix:[user=uid,][group=gid,][umask=mask,]file=path
1998 If file= is omitted the existing format is assumed, e.g.
2000 in which case the mask is 0666 (rw for everybody).
2002 Major restructure of YAZ source. All source in libyaz is in src directory.
2003 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2004 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2006 Added man page for utility yaz-marcdump (used to be called marcdump).
2007 yaz-marcdump is installed by 'make install'.
2009 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2010 of incoming package failed.
2012 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2014 Change prototype of odr_perror: add const to message string.
2016 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2018 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2019 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2020 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2021 DNS lookup. There should not be any compatibility problems with this
2022 assuming that blocking=1 or 0 is used.
2024 Fix bad reference in UNIX comstack in function cs_addrstr.
2026 Fix for compilation on AIX.
2028 The generic front-end server (server/seshigh.c) now supports returning
2029 Init diagnostics to the client in User-information-field, in
2030 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2033 --- 2.0.4 2003/09/04
2035 Allow any CQL relation (not just all,any,exact,scr).
2037 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2038 that features the same UI.
2040 Implemented command update0 in YAZ client which is equivalent to
2041 update but uses old of Ext Update ASN.1.
2043 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2044 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2045 Previously no OID was used for this info.
2047 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2048 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2049 returns 'malformed search term' otherwise.
2051 SortResponse member resultCount now set to NULL in sort handler of
2054 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2057 Add three new utility functions for translating OIDs between various
2058 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2059 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2060 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2061 char *oid_to_dotstring(const int *oid, char *oidbuf);
2062 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2064 Reverted modifications for ES Update definition for z_IU0Update
2065 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2066 is back to YAZ 2.0.2.
2068 String value attributes for CCL parser.
2070 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2071 which their FirstSearch server returns in Init responses, sometimes
2072 carrying useful diagnostic information when Init fails. This has the
2073 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2074 "z39.50/oclcui.asn", where its definition is somewhat different from
2075 what OCLC document on their web-site, as required to interoperate with
2078 Support for anonymous authentication in yaz-client. Use the command
2081 * Fix the OID of the Index Data-local "admin" Extended Service from
2082 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2083 the 1000, which indicates a locally-defined OID, was a mistake.
2085 --- 2.0.3 2003/06/20
2087 Fix CCL directive @case handling so that it affects string match for
2088 both CCL keywords and qualifiers.
2090 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2091 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2092 Decoder has been updated with ASN.1 changes as listed in
2093 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2094 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2095 z_IUUpdate, remains unchanged.
2097 ZOOM_record_get may now return a record in a specific character set.
2098 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2099 "from" is the character set of record as returned by target. "to" is
2100 the character set to be returned. If omitted, "to" is UTF-8.
2102 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2104 New ODR utility, odr_getelement, which returns name of element for
2105 which encoding/decoding failed.
2107 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2108 in cases where a required element was omitted.
2110 Bug fix: some MARC8 sequences were not converted.
2112 New ZOOM option "step" which specifies number of records to be
2113 retrieved in one chunk. Used in conjunction with "start" and "count".
2115 SRW support for yaz-client. Use scheme http: to use it, e.g.
2118 yaz-client no longer does (un)intelligent character set conversions
2119 by default. Can be enabled with charset and marc_charset commands.
2121 xmalloc trace fix for 64-bit systems such as DEC alpha.
2123 Solaris 2.6 compile fix.
2125 New function, cql_strerror() translates SRW error codes, as returned
2126 by cql_transform_error(), into human-readable English strings. Used
2127 in yaz-client diagnostics when appropriate.
2129 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2130 converts it into a type-1 query which is sent to the server. This
2131 makes CQL available for use with all Z-servers, as opposed to the tiny
2132 minority that can handle CQL queries themselves.
2134 --- 2.0.2 2003/04/28
2136 New Debian package layout similar to the Redhat Package layout.
2138 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2139 and search result respectively.
2141 --- 2.0.1 2003/04/25
2143 Redhat package is now several packages: libyaz (runtime libraries),
2144 libyaz-devel (development and documentation, and yaz (utility programs).
2145 Package spec file by Morten Bogeskov.
2147 New member 'schema' in struct bend_fetch_rr which the name of requested
2148 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2149 handler MAY set this to reflect the schema of the returned record.
2151 New member 'display_term' in struct scan_entry. GFS now sets member entries
2152 and allocates scan entries to be filled by user scan handler. In previous
2153 version, entries member was allocated by the scan handler. That still works,
2154 but the GFS will ignore member display_term - assuming it was NOT set by
2155 the handler. The fact that the GFS now allocates the entries both allows
2156 for new members and makes a scan handler easier to write.
2158 Fix CQL lex buffer overflow.
2160 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2161 SRU default recordPacking is string.
2163 SRU protocol support for frontend server.
2165 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2167 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2169 Added scan for the ZOOM shell (zoomsh).
2173 * String Identifers for Schemas (Amendment 5).
2174 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2175 Old definition for schema
2176 Odr_oid *schema; /* OPT */
2181 Z_InternationalString *uri;
2182 #define Z_Schema_oid 1
2183 #define Z_Schema_uri 2
2186 * resultCount parameter to Sort Response (Amendment 1).
2187 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2189 Support for SRW 1.0 over HTTP. This is an optional feature and
2190 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2193 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2194 on the same port. SRW SearchRetrieveRequests are mapped
2195 to bend_init,bend_search,bend_fetch,bend_close.
2197 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2199 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2200 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2202 ZOOM connections are SRW based if schem http is used for hostname
2203 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2204 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2206 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2207 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2208 distance=n, order=true/false, relation=le, prox unit=word. If
2209 n is omitted, distance 1 is used.
2211 Fixed problem with C compiler include path in wrong order.
2213 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2214 on Solaris. Patch from Ko van der Sloot.
2216 New MARC decode API. All new functions operate on a yaz_marc_t
2217 handle. The most important new functions are: yaz_marc_create,
2218 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2219 decode and destroy respectively. Decoder can produce formats
2220 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2221 include/yaz/marcdisp.h.
2223 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2224 to UTF-8, UCS-32, wchar_t or Latin-1.
2226 * Prototypes for yaz_iconv_-functions moved to separate header
2227 include/yaz/yaz-iconv.h.
2229 Make a few private functions 'static' in unix.c. This prevents
2230 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2232 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2233 are set when Init Response is received.
2235 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2236 but returns diagnostic set as well.
2238 New function yaz_strerror which is a portable wrapper for
2239 strerror/strerror_r/GetLastMessage.
2241 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2242 is returned for MARC. If type is "oai", then OAI MARC is returned.
2244 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2247 --- 1.9.2 2002/11/26
2249 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2251 Fix bad race conditions on SIGTERM and terminate gracefully in
2254 Move retrieval (data1) module to Zebra since nobody seems to be
2257 Add GRS-1 render for ZOOM using same format as yaz-client.
2259 --- 1.9.1 2002/10/05
2261 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2263 Fix broken ESpec handling in data1 module.
2265 SGML reader parses comments and makes them part of the data1 tree.
2267 Added several type casts so that YAZ compiles as C++ code.
2269 ZOOM didn't handle PDU encoding failures properly.
2271 Added more Bib-1 diagnostics (approved extensions).
2273 GNU configure: better check for iconv.
2275 More portable use of accept, getpeername. Check for socklen_t. Use
2276 int/size_t if socklen_t is not defined.
2280 PQF parser rejects bad queries - including those with extra
2281 characters in them. PQF parser used to silently ignore that.
2282 Cleaner API for PQF added, which allows you to get detailed
2283 error information for bad queries (see yaz/pquery.h).
2285 Fixed bug in ZOOM_record_get for type "database".
2287 Implemented mini iconv library supporting conversions between
2288 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2290 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2292 --- 1.8.9 2002/08/20
2294 Fixed ZOOM C record cache so that preferredRecordSyntax and
2295 elementSetName is used to check for already fetched records.
2297 --- 1.8.8 2002/08/02
2299 Added three members in bend_initrequest structure to facilitate
2300 character set negotiation.
2302 Fixed a bug in frontend server that could cause indefinite
2303 loops under rare conditions.
2305 Revised character set utilities (charneg.h) so that encoding
2306 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2308 For PQF, directive @term <type> sets term type for Scan/Search.
2309 Here <type> is general, string, numeric, null. The term type
2310 is inherited - just like @attr.
2312 New call odr_set_charset that sets character set conversion for
2313 international-strings on a ODR stream. Prototype is:
2314 int odr_set_charset(ODR o, const char *to, const char *from);
2315 The InternationalString is still represented as C string in YAZ
2316 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2317 won't). On the protocol level, you can use any encoding.
2319 Support for UNIX sockets in ZOOM.
2321 Solaris recv sometimes returns errno == ENOENT. It is treated as
2322 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2324 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2325 both client and server. Code by Morten Bogeskov.
2327 --- 1.8.7 2002/05/22
2329 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2330 that they can be used directly from Visual Basic. You must recompile
2331 your windows APP if you're using ZOOM.
2333 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2334 Commands "lang" and "charset" sets language and character set respectively.
2335 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2336 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2338 Attributes from multiple CCL fields may be OR'ed rather than merged
2339 using directive "@field or". Fields are still merged by default -
2340 equivalent to "@field merge".
2342 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2345 Fixed bug in zget for parameter ExtendedServicesResponse.
2349 --- 1.8.6 2002/03/25
2351 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2353 Client displays USR.1:SearchResult-1 (hits per term).
2355 Additional Search Info for search in Generic Frontend Server.
2357 Fixed CCL parsing of "field=s".
2359 WIN32 installer - using the excellent NSIS software from nullsoft.
2361 Fixed CCL parsing of "field = - <number>".
2363 Added function yaz_marc_decode that decodes MARC for line mode
2364 display or XML (similar to that used by JZKit).
2366 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2367 Z39.50. But ISO/ILL was, however.
2369 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2370 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2372 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2373 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2375 --- 1.8.5 2002/02/03
2377 New YAZ client features: Command completion and new commands:
2378 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2379 Code provided by Jacob Poulsen.
2381 New call oid_trav, that visits all registered OIDs via callback.
2383 Function ZOOM_record_get now returns const char pointer rather than
2384 void pointer. It saves a lot of type casts.
2386 For YAZ client, command "auth" now allows you to set authentication
2387 in IdPass style. It is enabled when three tokens are given - order
2388 is user, group and password.
2390 Fix memory leaks in MARC record handling for ZOOM.
2392 New option for YAZ client, -k <kilobytes> that sets
2393 maximum record size. Similar to -k option for generic frontend
2394 server and yaz-ztest.
2396 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2398 Prefix query parser reports "fail" when bad attribute set is given.
2400 Fix in MARC decoder. Proximity logging. Fix for attribute set
2401 in scan handler for server. Patches by Shigeru Ishida.
2403 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2406 Configure option --with-openssl=<dir> now works when a directory is
2407 specified. Patch provided by Morten Bogeskov.
2409 New option for YAZ client, -u <auth>, that sets authentication.
2411 ZOOM fix: error information was sometimes "missing", since error
2412 was cleared/reset too when it shouldn't.
2414 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2416 --- 1.8.4 2002/01/04
2418 Scan for ZOOM API. New object ZOOM_scanset. New functions
2419 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2420 ZOOM_scanset_destroy.
2422 New ZOOM function, ZOOM_connection_last_event, that returns type
2423 of last event (such as "receive data", "send data", "apdu received",
2426 New ZOOM option, schema, that specifies schema for retrieval.
2428 New CCL feature. Qualifiers can be aliases for one or more
2429 other qualifiers (if more than one is given, OR is used).
2431 ZOOM uses named result sets if target supports it.
2433 Two new YAZ client commands: . (dot, which sources a script of YAZ
2434 client commands), and ! (to execute shell command.). Implemented
2437 Working on Debian packages.
2439 --- 1.8.3 2001/11/19
2441 YAZ client enables named result sets only if target supports it.
2443 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2445 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2446 with key="host" to get same result.
2448 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2449 Function Z3950_resultset_record(s) returns references to records
2450 "owned" by resultset. To become owner use Z3950_record_clone.
2452 Function z_ext_record handles Extended Services. Thanks to
2455 --- 1.8.2 2001/11/12
2457 CCL Parser fix: ignore token comma when dealing with and-lists.
2459 Documentation updates for COMSTACK.
2461 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2462 Changed prototype Z3950_records. For some functions, int parameters
2463 were changed to size_t.
2465 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2468 New MARC decode/display function, marc_display_exl, which properly rejects
2469 non-ISO2709 records. YAZ client uses it.
2471 --- 1.8.1 2001/10/29
2473 Fix bug: local attribute set wasn't set correctly in PQF strings.
2477 * Old Z39.50 codecs no longer supported.
2479 Added ZOOM C binding. See http://zoom.z3950.org/
2481 Renamed states for COMSTACKs to avoid confusion with events.
2483 Implemented cs_look and proper cs_rcvconnect.
2485 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2487 Configure detects POSIX threads on OpenBSD.
2489 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2490 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2492 When error is returned from present handler, non-surrogate diagnostic
2493 is returned in present response (and fetch handler is no longer called).
2495 * Minor adjustments to pquery parser (PQF). Token characters may be
2496 escaped by using backslash (C-style).
2498 PQF parser allows string attribute values to be specified. For @attr,
2499 non-numeric characters after the equal-sign are treated as strings
2500 (e.g. @attr 9=title).
2502 CCL trunction character may be defined (@truncation in file)
2504 * function zget_ExtendedServicesRequest sets waitAction to
2505 waitIfPossible (was wait).
2507 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2510 CCL operator names may be set in field definition files (CCL_bibset).
2511 See ccl/bib1 for an example.
2513 Fixes in ASN.1 compiler for C++ compatibility.
2515 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2516 and "op_or" to avoid conflict with C++.
2518 Fixed problem with GNU readline detection on Redhat 7.0.
2520 Added step-size for Scan backend handler.
2522 Fixed bug that made the frontend server crash when no attribute
2523 set was specified for scan.
2525 Front-end server automatically switches to original working directory
2526 when installed as an NT service. Previously -w had to be specified to
2529 Added extended attributes for retrieval module (data1), so that data1
2530 records carry d1_readXML/SGML attributes. d1_read also supports
2531 null-data rules ( <tag/>)
2533 On UNIX when POSIX threads are available, a separate library libyazthread
2534 is created. Programmers should link with that library and the yaz library
2535 when using threads. The reason for the split was that some applications
2536 on Linux, such as Apache, doesn't work well when using shared objects that
2539 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2540 (or any frontend server) in SSL mode by specifying ssl: followed by
2541 address. Only tested on UNIX.
2543 Added feature for CCL module. Virtual structure s=al or s=ol generates
2544 and-list and or-list respectively instead of phrase search.
2548 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2549 log_mask_str. This was done to avoid name conflicts with other libraries
2550 (such as other PHP extensions).
2552 Added raw OID member for preferred record syntax (request_format_raw)
2553 and returned record syntax (output_format_raw) for backend fetch method.
2555 Config file yaz-config now accepts options so that it returns specific
2556 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2558 Shared library support for UNIX using GNU libtool.
2560 * Modified backend interface. Request/Response struct's replaced by
2561 one read/write C struct. For example bend_fetchrequest and
2562 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2563 Every handler - even search has to be registered in bend_init
2564 handler. This means that the YAZ library no longer refers to
2565 external functions and it makes it possible to make the whole
2566 thing a single DLL/SO.
2568 Added Segment handler for backend server.
2570 Added Zmbol/Zebra administrative functions to YAZ client.
2572 Threaded frontend server on UNIX (when POSIX Threads are available).
2573 Starting the server with option -T enables multi-threading.
2577 Added configure option --enable-comp/disable-comp to control use
2578 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2579 located in sub directory asn.
2581 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2582 in ${exec_prefix}/bin along with the other programs yaz-client and
2585 GNU automake used to maintain makefiles.
2587 Added several OID's.
2589 Changed retrieval module so that we can load records with no abstract
2590 syntax defined. Tagpaths in these records are fully composed of string
2593 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2597 On UNIX, the generated makefile now supports a proper 'make install'.
2598 The prefix can be set via GNU configure to set the install location
2599 (default is /usr/local).
2601 * YAZ programs client and ztest were renamed to yaz-client and
2602 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2603 locations, such as /usr/bin,/usr/local/bin,etc.
2605 * YAZ Header files were moved from include to include/yaz. YAZ Header
2606 files are referred to as include <yaz/log.h> rather than <log.h>.
2607 The YAZ include path (-I ..) is therefore the same as before. Programmers
2608 should update their #include statements or use -Ipath/include/yaz
2609 instead. The main motivation for doing this change is that YAZ header files
2610 can be installed in "standard" locations /usr/include,/usr/local/include
2611 without introducing conflicts, since ALL YAZ header files are stored
2612 in subdirectory yaz (under /usr/include for example).
2614 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2615 rather than project/workspace files. We switched because project files
2616 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2619 Changed name of logging function, logf, to yaz_log, to prevent name
2620 clash with some math-log functions. The YAZ header log.h defines logf
2621 to yaz_log (#define) so there should be no incompatibilities by this
2624 Added bend_start/bend_stop handlers for server. These handler are
2625 called on start/stop of server. For windows they are called whenever
2626 a service is started/stopped.
2628 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2629 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2630 in util/yc.tcl. The auto-generated C code structures are, in a few
2631 cases, incompatible with the old decoders. There are differences in the
2632 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2633 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2634 The preprocessor variable ASN_COMPILED is defined when the compiled
2635 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2636 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2637 wish to use the old encoders/decoders you can specify --disable-yc
2640 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2641 version so that it supports both new - and old version of DB Update
2643 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2644 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2645 change. The name parameter can be set to 0 in which no name is specified
2646 for the construction. The macros odr_implicit and odr_explicit sets name
2647 parameter to zero for the construction involved. New macros
2648 odr_implicit_tag and odr_explicit_tag are similar to the others,
2649 except that a name parameter is added. For programmers' that don't use
2650 ODR they probably only need to change the call to z_APDU and z_External.
2652 Added access control facility by interfacing the TCP wrapper library.
2653 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2654 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2655 name of the daemon and enables the access control as specified in
2656 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2658 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2659 den Dool <H.M.vdnDool@kub.nl>.
2661 Added reference ID parameter to most functions in server API - refer
2662 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2664 Changed name of ccl library to libccl.a (was ccl.a).
2666 Fixed bug in decoder for Explain (Category TargetInfo).
2668 Added support for GNU readline in client. Thanks to Jacob Poulsen
2669 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2671 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2672 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2673 IMPLEMENTATION! This change was made to the development version before
2674 the ZIG decided to retract the amendment. If any users MUST be
2675 compatible with the original Update definition, PLEASE CONTACT US, and
2676 we will include a separate definition corresponding to the old Update
2677 ES. Note that because of the change to the ASN.1 of the
2678 TaskPackageRecordStructure we cannot define a single structure that
2679 will support both versions.
2681 * Added const modifier to buffer parameter for some ODR/BER encoding
2682 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2683 completeWAIS, odr_dumpBER.
2685 Fixed bug in client.c which caused a crash when a scanResponse didn't
2686 contain positionOfTerm.
2688 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2689 * will cause an error in a client if a non-YAZ target sends both a
2690 * list of Scan entries and non-surrogate diagnostics.
2692 Retrieval module enhancements. Tag sets may be typed in the reference
2693 to it. From the .abs-file the "tagset" directive takes a third optional
2694 integer type for the tag set referenced. From a .tag-file the "include"
2695 directive takes a third optional type as well. The old "type" directive
2696 in the tag set itself is still recognized but acts as the default type
2699 Backend interface change. Individual Scan terms returned from bend_scan
2700 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2701 in include/backend.h.
2703 Retrieval module enhancements. Multiple tag sets and attribute sets may
2704 be specified in abstract syntax specs. Revised the error/warning for
2705 logging messages reported by the retrieval module when reading the
2708 Object Identifier system (oid_..) changed. The API is backwards
2709 compatible but the oid-routines now allocates new OID's when needed.
2710 Raw OID's may be specified in oid_getvalbyname.
2712 YAZ now uses GNU configure to generate Makefile(s).
2714 * Minor changes in some of the member names of DeleteResultSetRequest and
2715 DeleteResultSetResponse. See include/proto.h.
2717 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2718 and added member 'languages' in TargetInfo (which was missing).
2720 Changed the way attribute sets are handled in the retrieval
2721 module. These are now cached, just like the abstract syntaxes
2724 Changed YAZ so that it links with compiled ASN.1.
2726 Added Explain-schema definitions and mapping routines. The following
2727 Explain categories have been implemented: AttributeDetails,
2728 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2730 Fixed minor bug in Windows version of Server Library.
2732 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2734 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2736 Added EXTERNAL: UNIverse Resource Report (non-standard).
2738 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2739 ENUMERATED and SET OF.
2741 * Added 'const' to some of the char pointer arguments for the
2742 functions, data1_read_node, data1_getelementbytagname,
2743 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2746 Fixed bug in data1_insert_taggeddata - the last_child member of
2747 parent wasn't initialised.
2749 * Changed data1_read_record and data1_read_node so that the supplied
2750 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2751 doesn't refer to any parts of the "SGML"-buffer.
2753 Fixed bug in server library (Windows version of statserv_remove).
2755 * Changed code so that it compiles as C++. The type definition
2756 of Odr_fun which is a member of Odr_arm was changed. The result is,
2757 that an explicit typecast is needed for the fun pointer when
2758 using Odr_arm - as in:
2759 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2761 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2763 Implemented the new structured date and time definition as approved
2764 by the ZIG. Added schemaId element to the specificTag in Espec-1
2765 (also approved at the last ZIG). Thanks to RVDM.
2767 Added some Object identifiers (RVDM).
2769 Changed the Update Extended Service (RVDM).
2771 Added command "refid" to client which specifies referenceId for
2772 the following requests.
2774 Implemented extended service handling for server. See ztest.c
2775 for an example as well as backend.h. New handlers are registerd
2776 in the Init handler.
2778 * Changed interface for sort in server.
2780 Added new members to statserv_options_block. It allows a server
2781 to read options from another source than just the command line. Thanks
2782 to Charles Woodfield.
2784 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2785 renamed to zboolean. Some C++ compilers complained about the name.
2787 Minor changes to gils.abs. Added index 's' (sort) on title
2788 and date/time-last-modified.
2790 --- 1.4pl2 1998/1/30
2792 Fixed bug in server library regarding inetd mode (-i). This bug
2793 was introduced by release 1.4.
2795 --- 1.4pl1 1998/1/29
2797 Added sort facility in client and backend server interface.
2799 Fixed problem with dependencies in Makefile(s).
2801 Fixed bugs for encoders/decoders of extended services and
2804 Implemented sub-tree feature for schemas. Sub-trees are
2805 referenced in *.abs-files. See explain.abs for an example
2806 of the use of this feature.
2808 Modified bib1.att; local attributes for ANY didn't include
2809 ANY itself (only affects use of the retrieval module).
2811 Fixed bug in plain SGML reader in function data1_read_node:
2812 tags with prefix "var" was incorrectly interpreted as variants.
2814 Added feature "sub-schemas" to enable references to - and definitions
2815 of - group of elements.
2817 * Removed member parent from type data1_element (in data1.h).
2819 Implemented function odr_nullval() that returns the value of
2822 * Removed member num_children from data1_node (in data1.h).
2824 Made NT service interface part of the server library. The
2825 function statserv_main uses the NT service when required and
2826 calls the statserv_start / statserv_close routines.
2828 Routine zget_SearchRequest and zget_PresentRequest fills
2829 resultSetName/Id member with "default" instead of "Default".
2831 Fixed memory leak in server. Request queue member wasn't freed.
2833 Fixed nmem_exit so that memory is freed.
2837 Revised the CCL parser utility to be thread safe.
2839 Added function, oid_ent_to_oid, to replace the function
2840 oid_getoidbyent, which is not thread safe.
2842 * Added nmem_init and nmem_exit to initialize and release
2843 NMEM resources. Function nmem_init should be called once in the
2844 initial thread before NMEM/ODR is used. statserv.c and client.c
2845 have been changed accordingly. The change was necessary to make
2846 NMEM thread safe. The NMEM memory pool is shared amongst threads
2847 in a process. Unix-based applications will still work fine without
2850 Added NT Services interface for the the Z39.50 (statserv) Server.
2851 Refer to the ztest.c source on the usage.
2853 Windows 95/NT port using MSVC5.0. Project files are included in the
2856 * Defined new 'global' handle for the retrieval (data1) system. The
2857 new handled, data1_handle, describes the state of the data1 system.
2858 This handle is passed as first argument to virtually all
2859 data1 related routines. The functions data1_create and data1_destroy
2860 creates and destroys a data1 handle respectively.
2862 Added ODR encode stream member to all backend request structures
2863 init, search, scan etc. This stream should be used to allocate all
2864 memory used for the response when thread safe operation is needed.
2866 Changed the comstack utility, cs_addstr, to be thread safe. The
2867 returned hostname string returned by the function is now part the
2870 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2871 function. The cs_straddr takes a COMSTACK handle as argument, so this
2872 function must be used after cs_create and before bind/connect.
2873 This function is thread safe.
2875 Moved test server to 'ztest' directory - generic server code still
2876 in 'server' directory.
2878 Made prefix query (pquery.c) utility thread safe.
2880 Added new function modifier YAZ_EXPORT to 'export' public DLL
2881 functions when using windows (see include/yconfig.h).
2883 Added definitions to the OID database (util/oid.c) (RVDM).
2885 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2887 Added call to ccl_rpn_delete in client program.
2889 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2890 release of RPN structure.
2892 Added support for C++, headers uses extern "C" for public definitions.
2893 With input from RVDM.
2895 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2896 Thanks to Ronald van der Meer (RVDM).
2898 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2900 Added support for private extensions to the OID database
2901 (oid_setprivateoids()). Thanks to RVDM.
2903 Added optional, physical ANY (key replication)
2905 Fixed null-reference problem in GRS-1 output filter.
2907 Proximity operator added to Prefix Query Format (PQF).
2909 In test client command "base" accepts multiple databases.
2911 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2915 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2917 Smallish bug-fixes in the new encoders/decoders (explain).
2919 Bug fixed in DeleteRequest.
2921 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2923 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2925 Added SOIF syntax (using private OID for now) to retrieval module and client.
2927 Added Update extended service.
2929 Added SearchResult-1 additional info structure.
2931 Added optional CCL (ISO8777) interpreter as separate module. Available
2934 --- 1.2 1996/6/10 (1st anniversary release)
2936 Added Summary record syntax. Lightly tested.
2938 Added OPAC record syntax. Untested.
2940 Added ResourceReport service encoders/decoders. Untested.
2942 Fixed bug in z_Unit - wrong tagging on unitSystem.
2944 Fixed bug in the DiagRecs decoder.
2946 Added options for max PDU size and session timeout to frontend-server.
2948 Added documentation of query-language parsers and other supporting utilities.
2950 [frontend-server] Added Attribute set to the bend_scanrequest API.
2952 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2953 surrogate diagnostics were generated.
2955 [retrieval] Allow multiple local values for attribute.
2957 [retrieval] Allow multiple attributes per element in .abs files. index type.
2959 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2961 --- 1.1pl2 1996/4/10
2963 Minor changes, mostly specific to Zebra's requirements (retrieval)
2967 Repaired bug in frontend server when running multiple listening
2968 endpoints in dynamic mode.
2970 z_External() now won't break if a known, ASN.1 value comes encapsulated
2971 in an octet-string. The value will pass through unmodified in an Odr_oct.
2973 Added a bit of code to the demo client to decode & display
2974 ASN.1-structured records represented in the octet-aligned branch of
2975 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2977 Added z_ext_getentbyref() to the ASN module. Doc updated.
2979 * Completed the SCAN definition in the ASN module. This may break SCAN
2980 code based on older YAZ-versions at compile-time. The fix is easy -
2983 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2984 under the SCAN definition. Remember to initialize this, server-people.
2986 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2987 that this does not extend to ODR and ASN.
2989 Comstack allows insertion of established socket (primarily for
2990 inetd-operation of servers). Doc updated.
2992 Front-end server can now start from the inetd in TCP mode. Doc
2995 --- 1.0pl4 1996/1/24
2999 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3000 the rank and record number.
3002 Adjustments to the frontend server.
3004 Fixed diagnostic BER dumper. It ignored the file argument.
3008 Various changes to retrieval module.
3010 Changed the union discriminators of the protocol files from enums to
3011 ints paired with #defines.
3013 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3016 *Changed operator in the RPN structure to 'roperator', again to avoid a
3019 Fixed problems in Explain decoders/encoders.
3021 --- 1.0pl2 1995/12/6
3023 Memory bug in log module fixed.
3025 --- 1.0pl1 1995/12/5
3027 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3029 Bug in Explain DatabaseInfo module fixed.
3031 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3035 The shift to v1.0 signals that we now consider the *core* functionality
3036 of YAZ reasonably stable (the core being more or less equivalent to
3037 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3038 tested (Explain not at all - though that will happen soonish).
3040 Minor changes to code to support Windows port.
3042 Various minor changes after we're getting to use GRS-1 & co. more.
3044 Added Espec-1 format.
3046 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3047 of the protocol and it cannot be selected when encoding (maps into 'string'
3048 when decoding). Needed to talk to some servers.
3050 Demo client can request simple element set names.
3052 Added Diagnostic Format encoders/decoders.
3054 Added simple Close handling to frontend server (no hooks for resource
3055 reporting yet), and demonstration client.
3057 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3059 --- 1.0b3 1995/08/24
3061 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3062 handled incorrectly when records were requested in the searchResponse. This
3063 will only affect you if you use the frontend-server.
3065 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3066 Test-client will ask for and print GRS1. Ztest will return dummy records
3069 Added Explain encoders/decoders to the service-level API. Untested.
3071 Added Extended Services: Item Order encoders and decoders to the Service-
3072 level API. Untested. We could use a recent copy of the pertinent bits
3073 of the ILL protocol to add those bits.
3075 Added diagnostic format 1 encoders/decoders to the service-level API.
3078 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3079 odr_cons.c, which causes a more correct output.
3081 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3082 was always set to 0 when no records were requested in the searchRequest.
3084 * Added better external-handling. This shouldn't harm old code that
3085 *encodes* externals. It can break code that looks for a
3086 'single-ASN1-type' representation, since those types that are known
3087 are now decoded immediately. Look at the SUTRS sample code in
3088 seshigh.c and client.c. Documentation updated.
3090 Handling of structured records in bend_fetchresponse. Length -1 marks
3091 structured record, type is deduced from format field.
3093 --- 1.0b2 1995/06/27
3094 Fairly quick maintenance release to add SUTRS support.
3096 Fixed handling of SUTRS records in the demonstration client.
3098 * Added format field to the bend_fetchrequest and bend_fetchresponce
3099 structures of the backend API (frontend server). When the record is
3100 returned, the value of the format field is mapped to an OID. The
3101 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3102 of the record. The special value VAL_NONE in the bend_request means
3103 that no specific format was requested by the client. Documentation
3104 updated accordingly. Test server (ztest) will return a fixed dummy
3105 SUTRS record if your client requests SUTRS.
3107 Documentation updated accordingly.
3109 You can now set external libraries and RANLIB support in the top-level
3113 First public release.
