3 Fix uninitialized variable in Solr spell support (could cause SEGV
4 for SRU response decoding).
6 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
7 back-end's addinfo through into the ZOOM response addinfo.
9 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
10 they are separated by a colon and a space rather than simply
15 Add support for Solr spell-checking/suggestions through ZOOM.
16 If a Solr target has been configured correctly for spelling-checking
17 and suggestions, these will now be returned on the ResultSet option
18 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
22 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
23 with a flag whether to substitute escape sequences or not.
27 Fix nmem_strsplit_escape to substitute escape char properly.
29 New option for zoomsh -e , which makes it abort on first error and
30 return process exit code to indicate success/failure.
32 YAZ options utility supports special option -- which makes all it treat
33 all following arguments as non-options.
37 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
38 searched if absolute filename is given.
40 Fix conv_xslt() error-reporting when stylesheet is not found.
41 (The value of fullpath is meaningless in this situation.)
45 Fix problem in CQL sort node creation: un-initialized memory.
47 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
48 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
49 CQL sortby depending on whether Type-1 or CQL is actually sent to the
52 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
53 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
55 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
56 will make it possible to use both single-character mask (#) and wildcard (?)
57 in CCL . Throw diagnostic for left truncation because that is not supported
62 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
63 cases using escapes (\-sequences) and masking.
65 PQF parse fix: A trailing backslash followed by end-of-string (\0)
66 would result in a read one byte beyond string.
68 rpn2ccl may use Z39.50 masking for terms (t=z).
70 ICU check fix. Don't include library -lCrun on Solaris, unless present.
72 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
73 not --cppflags (which seeems like an error in icu-config).
75 -- 4.2.12 2011/08/27 RPM package only
77 cql2ccl: fix conversion of terms: operator characters were not
80 -- 4.2.11 2011/08/25 RPM package only
82 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
83 CCL parser will map both # and ? to their regular expression
84 quivalents (. and .*).
86 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
87 of reserved CQL characters.
89 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
90 is, so that they are passed through.
94 ZOOM SRU mode: more aggressive re-connect.
96 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
97 made available as a utility function, declared in <yaz/logrpn.h>
99 rpn2cql_structure() supports proximity nodes (except that the Type-1
100 proximity node's "exclusion" binary is ignored, as there is no way to
101 express that in CQL). Fixes bug #4564.
105 Fix SEGV that could occur if set command of zoomsh was given without
106 value (2nd argument).
108 Fix SEGV that could occur if unsupported transport was given for
109 COMSTACK - say https (when SSL was unavailable).
111 Build yaz-url on Windows too.
115 New utility to get web content. Header is url.h. A command line tool
116 yaz-url is part of the distribution and packages.
118 Fixes for SSL COMSTACK (when gnutls is in use).
120 New functions yaz_base64{encode,decode}. Header is base64.h.
124 ZOOM C includes HTTP response buffer as additional info if it fails
125 to decode the SRU response.
127 Make wrbuf_json_puts available.
131 zoom: throw diagnostic for invalid value for option "sru". Before a
132 bad SRU request was sent.
134 Adding new utility wrbuf_vp_puts.
136 Add cclxmlconfig.obj to win/makefile. It was missing completely.
140 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
141 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
142 redirect was used at the same time.
144 MARC line mode decoding: be less picky about length given - first
145 5 digits of header that is.
147 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
149 Changes to decoding of SRU records: a record with recordPacking=xml is
150 modified with a new root element <yaz_record> if the recordData contains
151 multiple children elements. This is to make the record XML parseable
154 RPN to SOLR conversion: encode special characters.
156 Generic Frontend Server: fix uinitialized member, stepSize.
160 Fix a bug in SRU decoding of records.. The database records stored
161 had un-initialized memory, but it would only be seen with yaz_record_render
162 and type_spec="ext" .
164 Fix a bug in ccl_qual_dup introduced in 4.2.3.
168 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
172 Add new utilities to convert from CQL to CCL . These utilities have
173 prefix cql_to_ccl defined in cql.h.
175 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
176 lead to memory heap corruptions when ICU utilities were in use.
180 Make compilation work without Libxml2.
182 yaz-client: remove redundant blanks in display of searchResult-1 term
187 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
188 resulting CQL node (tree) in a new node CQL_NODE_SORT.
190 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
191 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
192 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
193 Note that the CQL sortby spec is only converted when the GFS is already
194 converting from CQL to RPN (cql2rpn element).
196 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
197 specify whether to collapse delimitors or not. The existing nmem_strsplit
198 do collapse (collapse parameter = 1).
200 Windows installer: For NSIS, set InstallDir depending on x86/x64.
202 Rename internal func yaz_use_attribute_create. While non-static, this
203 function is not declared in a public header.
207 Add -lCrun when linking with ICU on Solaris.
209 More quicks character set conversions for OPAC records.
213 fix problem with record_render: records were converted (character set
214 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
218 SRU: add methods for handling DADS SRU-proxy facets.
220 Separate OPAC record character set for ZOOM_record. yaz_record_render
221 allows a character set given as charset=from/opacfrom,to where 'from' is
222 the character set of a bibliographic record, 'opacfrom' is character set
223 of OPAC record and 'to' is the target character set.
227 yaz-client: show may XML format records. Command show followed by 'format'
228 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
231 src/stemmer.c: Avoid using unnamed union. It is not supported by some
234 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
237 Update yaz.spec to operate on both SLES11 / Centos 5.5.
239 RPM: Release includes 'indexdata' name. Use indexdata in release name so
240 this package can be distinguished from other vendors.
242 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
243 as determined by configure
245 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
247 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
248 returns no error and no record, the present request is considered
249 partial (only a subset of the records could be returned by backend), and
250 so it is appropriate to set Present Status to partial-4.
254 Move yaz-config man pages to section 1.
256 More documentation about SOLR.
258 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
259 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
260 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
261 peers on some Linux systems. However, in general that does not work
262 so YAZ can not rely on that to work. Debian changed behavior in this
263 respect from Debian lenny to Debian squeeze (still testing as of Oct
265 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
267 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
271 Fix yaz-config output: echo_source not set correctly by configure.
275 SOLR WebService support for yaz-client and ZOOM.
277 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
279 --- 4.0.12 2010/08/17
281 Z39.50 facet support. Facet specifications are passed for search in
282 other-information with ASN.1 as defined in facet.asn and OID
283 .10.1000.81.5 . Facets are expressed as an Attribute list as known
284 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
285 3 is limit (number of entries to get in response). yaz-ztest returns
286 dummy facets if a client asks for them.
288 --- 4.0.11 2010/07/09
290 CCL fixes: bug 2895 and bug 3539.
292 GR1-display: add comma in display - was removed by mistake in
295 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
297 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
299 --- 4.0.10 2010/06/18
301 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
302 result set from a connection. The result set will be on its own
303 thereafter; no operations on it will perform retrievals from a target.
304 Only cached copies are returned.
306 ZOOM C:fix case for HTTP servers responding with Connection:close.
307 Ensure that if there is a current task it is resumed (like fetching
308 more records in a result set) . Bug #3484.
310 PQF parser: use odr_atoi for Odr_int (not atoi)
312 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
313 values that contain any non-digits are treated as string attributes
314 (previously decoding only checked for leading character ([0-9]). PQF
315 encoding: attribute string values are not surrounded by double-quotes.
319 New utility for managing threads - thread_create.h.
321 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
322 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
323 but YAZ' implementation do.
325 Fixes for yaz_cond-functions on Windows 7.
327 DLL export more symbols.
329 zoomsh: show record do NOT render opac.
331 Remove *.la files from Debian and RPM packages.
335 Debian package libyaz-dev depends on libgnutls-dev again (was
336 removed in YAZ 4.0.6, but due to Libtool it is still needed
337 even though yaz-config do not list libgnutls libs).
339 ZOOM: Use only one WRBUF for returning string results for
340 ZOOM_resultset. Reduces memory usage for ZOOM in general.
342 ZOOM: ZOOM_connection do not use a shared pointer to
343 ZOOM_resultset after ZOOM_resultset is destructed by
344 user. Reverts to YAZ 4.0.4 behavior.
348 record-conv: fix problem with at least one XSL conversion -
349 due to probably incorrect usage of XML XSL documents.
353 Fix yaz-config for static mode and the use of SSL (gnutls).
357 Forward decl timeval struct in mutex.h and gettimeofday.h.
359 yaz-config: fix 'static' mode linking.
363 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
364 are wrappers for pthreads or Windows. For Windows these are put in
365 a separate DLL: yaz_cond4.
367 libyaz.la (whole source) is compiled with thread. If thread support
368 is enabled enabled, all source of YAZ is compiled with treading support.
369 This allows core utilities such as yaz_log to use thread facilities.
370 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
371 thread utilities. This commit moves mutex utilities (mutex.c) from
372 libyaz_server.la to libyaz.la.
374 yaz-json-parse displays leading text until error.
378 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
379 patch from Giannis Kosmas.
381 SRU: no longer URL encode SRU database. The URL for an SRU server is
382 a URL and such is alreeady encoded - at least when given with leading
383 http:// or https://. This reverts behavior to YAZ 3.0.50.
385 Support for new MARC XML notation TurboMARC which like MARCXML is a
386 complete representation of MARC/ISO2709.. This one, however, is more
387 compact and allows for faster processing with XSLT. TurboMARC can be
388 used in the marcdisp.h API, from the yaz-marcdump utility and from
391 yaz-ztest can be configured - via the database - to perform certain
392 delays when it performs operations search, present and single record
393 fetch. This allows testers to make yaz-ztest act as a real or even slow
394 Z39.50 server. Refer to the yaz-ztest man pages for details.
398 wrbuf_destroy allows NULL WRBUF passed to it.
400 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
402 Add ZOOM_connection_close.
404 No fixed size buffers for ZOOM shell - bug #3257.
406 tstodr: make it work on s390 platform.
408 New icu iterator-functions. The new icu_iter-functions makes it possible
409 to use ICU chains from many threads.
411 yaz-client: better syntax check for show command.
415 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
418 New simple local-file XML include facility which allows file glob-patterns.
419 Refer to yaz/xml_include.h.
421 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
424 ZOOM_record_get supports new parameter "format" which makes it format XML
427 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
428 JSONText in ECMA-262) is JSONValue, not JSONObject.
432 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
433 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
435 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
436 POSIX/Unix builds .so with major version 4.
438 Remove old LOG_-defines from log.h. They have been obsolete and
439 undefined by default for the last 5 years.
441 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
443 GFS: Remove socket (int *fd) from search_rr handler. The socket
444 descriptor ptr is a facility that allowed a search handler to supply
445 a socket which would serve as a callback - when search was complete.
446 This facility has now been in use for years.
448 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
449 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
450 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
451 returns 'const char *' rather than 'char *. The returned string is
452 read-only and should not be modified by applications. COMSTACK cs_close is
453 now a void function - it no longer returns int. No applications check for
454 the value and the implementations has always returned 0.
456 ZOOM: use size_t for scan hit counts and str size. Functions
457 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
458 occ (hit count) and len (string length) are now of type size_t pointer
459 rather than int pointer. This is to be able to represent large hit counts
460 and to also just to use the proper type for string length (strlen result).
462 New JSON parser. Refer to include/yaz/json.h .
464 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
465 Used to be int in some cases. Many wrbuf_-functions used to return an int
466 indicating some length.. These return values were never used. And so they
469 ODR: odr_malloc, odr_total now takes size_t for size.
471 clone_z_type: fix leak; occurred for encoding failures.
473 --- 3.0.52 2009/12/03
475 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
476 bug was introduced in 3.0.51.
478 --- 3.0.51 2009/12/02
480 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
482 tcpip comstack: fix leak for getaddrinfo.
484 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
485 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
486 Decoding of SRU "path" database is performed by private function
487 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
488 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
490 yaz-client: honor base command for SRU. Change when database setting
491 is applied for SRU and ensure it is kept when a connection is reset.
492 Change also the way errors are displayed or SRU (decoding of packages).
494 --- 3.0.50 2009/11/02
496 Add support for extra request / response data for SRU codecs and GFS.
497 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
498 for extra data response buffer and length. For the GFS, both request
499 and response data (XML) is carried in extra_args and extra_response_data
500 for the search handler. Patch by Ko van der Sloot.
502 ZOOM: For queries that cannot be converted to the specified rpnCharset,
503 ZOOM now returns a diagnostic on the client-side ('invalid query' /
504 10010). This fixes bug #2113.
506 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
507 cmdfile included a 'quit' command that would result in a memory violation.
509 --- 3.0.49 2009/10/01
511 Make a number of functions defined in xmlquery.c static. These have
512 never been declared in a public header file (yaz/xmlquery.h) and was
513 made public by mistake.
515 Improve speed of character conversions (iconv utilities). This makes
516 conversions from MARC-8 faster.
518 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
519 unless type desired is "raw". This will prevent type "xml" from
520 returning ISO2709 .. Which obviously can not be XML parsed.
522 Fix memory leak in ZOOM that would occur if option apdulog was used
523 on a re-used connection.
525 Frontend server logs HTTP requests.
527 Frontend server now sends Z39.50 close when it times out (sesssion has
528 been idle for too long). Versions 2.0.30 and earlier also sent close.
529 But due to a mistake this was disabled in all versions after that, i.e.
530 the server would just close the socket immediately.
532 yaz-client emits a better message when receiving an unrecognised
533 userInformationField.
535 Skip zero-length subfields when decoding ISO2709. This rare case happens
536 if a record has two FS characters in a sequence. Without this patch
537 there would be a reference beyond char array in using_code_len fragments
540 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
542 --- 3.0.48 2009/08/28
544 The show command offered by the zoomsh command now takes a 3d optional
545 parameter type which is what is passed to ZOOM_record. If the type
546 argument is omitted, "render" is used.
548 RPN to CQL conv may use USE string attributes (bug #2978).
550 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
552 --- 3.0.47 2009/07/08
554 Function yaz_xml2query allows a diagnostic element in the PQF XML
555 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
556 code and additional info respectively.
558 The BER BOOLEAN is now the integral type Odr_bool which still happens
559 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
560 typedef'd to Odr_int. This is still an integral 'int', but it may be
561 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
562 ASN-1 compiler as well as programs has been updated to use the new types.
564 --- 3.0.46 2009/06/08
566 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
567 only the bibliographic record was rendered. For type=opac, an OPAC
568 record is only returned if it is present.
570 iconv: small fix for encoding of advancegreek.
572 yaz-client: avoid double display of SRU/SRW records (bug #2798).
574 yaz-client: option auto_reconnect=on really reconnects.
576 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
578 server: avoid null ptr ref for for yaz_poll errors.
580 build: fix RPM build for RHEL 5.3.
582 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
584 --- 3.0.45 2009/03/31
586 Fixed bug #2709: TCP connect returns Invalid argument.
588 Fixed compilation for mingw.
590 Honor charset for raw records (ZOOM_record_get).
592 Fixed use of errno for threaded mode that was seen on Solaris 10.
594 Fixed argument passing with blanks in value for Windows Service.
596 Disable YAZ' own log rotate by default (no 1 GB limit).
597 The variable l_max_size which specifies the log file limit is set to 0
598 (DISABLED): This is due to the fact that YAZ is most often deployed using
599 logrotate. Also YAZ can not perform log rotate because of unsufficient
600 permissions (setuid).
602 --- 3.0.44 2009/02/17
604 List supported encodings in man page for yaz-iconv.
606 Fixed missing SSL libs for --libs output
608 Re-established OID record syntax application-xml. Nobody should use it
609 but we don't want to change soname because of this symbol being absent.
611 --- 3.0.42 2009/02/02
613 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
615 Added member named_result_sets for init handler struct for the GFS. This
616 allows a server to disable named result sets.
618 Removed OID record syntax application-xml.
620 Added support for rule-based transliterator for ICU wrapper of YAZ.
622 Fixed bug #1902: yaz-icu XML output.
624 Make YAZ checks Emacs friendly.
626 BITSTRING value shows value. Bug #2346.
628 ISO2709 decoding: skip control characters from indicator data.
630 Omit sort key by default in yaz-icu's output.
632 Allow combined single char options (again) for YAZ' options function.
634 Utility yaz-marcdump got option to display YAZ version (-V).
636 Allow YAZ to use ICU 3.4.
638 Added new ICU test case which illustrates removal of diacritics.
640 --- 3.0.41 2008/12/29
642 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
644 --- 3.0.40 2008/12/29
646 For configure, using option --without-xml2 also disables Libxslt/Libexslt
649 Fixed bug #2352: yaz-marcdump crashes for certain record.
651 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
653 Added support for Danmarc2 to UTF-8 conversion.
655 Added support for ISO5426 to UTF-8 conversion.
657 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
658 implementation version.
660 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
662 --- 3.0.38 2008/11/10
664 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
665 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
667 ZOOM C now interprets databaseName option for ZOOM connection as path
670 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
672 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
674 Dummy Libxml2 types no longer defined in headers of YAZ'.
676 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
679 --- 3.0.36 2008/09/26
681 Various ODR chapter fixes.
683 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
685 Added missing source for Windows compilation, mutex.c.
687 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
689 For SRU connections in ZOOM all records up to "count" are now fetched.
691 Fixed crash in generic frontend server (and yaz-ztest) which occurred
692 in Windows due to bad error handling for Libxml2.
694 Added facility for sending arbitrary records (ASN.1 any) using
695 ZOOM C's Extended service update. Patch by Sam Reynolds.
697 New options for ZOOM C's connection, logapdu which makes ZOOM log
700 --- 3.0.34 2008/06/18
702 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
704 --- 3.0.32 2008/06/12
706 Fixed memory violation that could occur when decoding UTF-8. This bug
707 was only present in 3.0.30 of YAZ.
709 --- 3.0.30 2008/06/06
711 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
712 GNU TLS is used by default (if found).
714 yaz-ztest returns OPAC records if a client asks for OPAC.
716 Improved speed of MARC-8 encoding.
718 Added support for lossy and loss-less MARC-8 encoding.
720 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
722 Added new Windows Service wrapper (sc).
724 yaz-client's itemorder command may now send a file.
726 Fixed yaz-marcdump to allow the use of NS prefix for record element.
728 Added new function yaz_log_xml_errors.
730 Allow (but warn) unknown XML attributes in MARCXML parsing.
732 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
734 The UTF-8 to MARC-8 conversion now uses a different set of characters
735 for Greek symbols. Bug #2120.
737 --- 3.0.26 2008/02/21
739 Added yaz_daemon (daemon.h).
741 Fixed bug #2068: pkg-config trouble
743 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
745 --- 3.0.24 2008/01/28
747 Document --with-xml2 option.
749 Added OPAC XML XSD (etc/opacxml.xsd).
751 Allow glob mask for name attribute in retrieval element for the
752 generic frontend server's retrieval facility.
754 Changed yaz_poll_poll to return yaz_poll_except for all returned events
755 except POLLIN/POLLOUT.
757 Fixed error handling in cs_listen. Bug #2037.
759 --- 3.0.22 2008/01/20
761 Fixed version in yaz/yaz-version.h.
763 Fixed bug #2027: Crash when closing connection.
765 Changed configure so that ICU support is only enabled if only ICU
766 and Libxml2 is available (because the ICU chain is XML based).
768 --- 3.0.20 2008/01/15
770 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
771 is built. Only this DLL depends on the ICU runtime.
773 yaz-ziffy is no longer part of YAZ. It is distributed separately by
774 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
776 Changed license of CCL module to 'Revised BSD'. After consultation with
777 remaining members of the original EUROPAGATE consortium, we are re-issuing
778 the CCL module without a separate license. The software was developed by
779 Index Data as part of a research project. The special license was included
780 to help feed usage information back to the project consortium to support
781 project evaluation. At this time, the project consortium has long-since
782 disbanded, and the majority of the original principals have retired. At the
783 same time, we have significantly modified the software during the following
784 years, to the point where very practically no original code remains. To
785 simplify re-use of the software, we have contacted those members of the
786 consortium who could be reached, and agreed to re-issue the module as a
787 proper part of the YAZ package.
789 Tcl scripts uses /usr/bin/tclsh as preferred shell.
791 CQL closer to being version 1.2 compliant. CQL also allows free-form
792 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
795 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
796 bug could make Extended services handling crash in the ZOOM layer. This
797 bug was only present in YAZ 3.0.18.
799 --- 3.0.18 2007/12/19
801 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
804 yaz-marcdump reads and writes collection wrapped records.
806 Handle OPAC for record conversion module.
808 Fixes for ICU wrapper.
810 Allow ICU libs to be controlled with --with-icu .
812 --- 3.0.16 2007/11/12
814 Added yaz_poll which is a wrapper for select/poll. When poll is available
815 and non-buggy, it is used, by yaz_poll . This allows more than 1024
816 sockets to be in use.
818 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
819 functionality through an XML based configuration (ICU chain). This system
820 is useful for search facilities such as Pazpar2 and Zebra that needs to
821 perform tokenization of indexed material. The ICU code in a separate
822 library libyaz3_icu.a.
824 Added HTTP tunnel facility for COMSTACK, bug #1752.
825 This is a facility that allows a Web proxy, such as squid, to tunnel
826 Z39.50 traffic. This facility is "transparent" to must applications
827 using YAZ. It's enabled by using pseudo transport connect: followed by
828 the proxy address, followed by command, then follwed by he regular
829 "virtual" addresss. For example,
830 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
832 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
834 --- 3.0.14 2007/09/21
836 Fixed bad memory reference in ZOOM_record - cuased by member not being
837 initialized. This was a problem only in YAZ 3.0.12.
839 Fixed bug in conversion from MARC to XML: Non-XML characters in control
840 fields were not removed.
842 Changed the way C code is generated from codetables.xml. Made a MARC-8
843 conversion trie for each characterSet section rather than codeTable.
844 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
845 of codetables.xml from Larry Dixson, LOC. Bug #1464.
847 --- 3.0.12 2007/09/12
849 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
850 from ZOOM_record_error).
852 ZOOM C function ZOOM_record_get returns record schema for type="schema".
854 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
856 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
858 Better SRW-to-Bib-1 diagnostic mapping.
860 ZOOM C and yaz-client announces SRU version 1.2 by default.
862 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
865 Fixed in yaz_sru_decode to allow other version than 1.1.
867 --- 3.0.10 2007/08/22
869 Added support for SRU scan for ZOOM.
871 Added support for the use of the older versions or Extended Service
872 Update in ZOOM. To faciliate this, an option "updateVersion" may be
873 set to the version , 1=first, 2=second, 3=third. The third version is
874 what ZOOM C has used so far. And that, obviously, is the default.
876 Added support for CCL queries in Z39.50 queries sent to the GFS (and
877 therefore in Zebra and in SimpleServer-based applications). The new
878 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
879 qualifier file used to transform incoming CCL queries into Type-1 RPN,
880 which is passed into the back-end search callback function.
882 Added support for HTTP Basic authentication in clients: the SRU/W
883 codec encodes the username/password elements of the PDU structure
884 appropriately, and these may be set using the "user" and "password"
885 options in ZOOM-C applications (the same options that are used for
886 Z39.50 authentication).
890 Fixed bug #1208: SSL appears to be broken in ZOOM.
892 Fixed bug #1206: Libxml2 include path weirdness.
894 Added oid_name_to_dotstring.
896 Allow elementSetName to be specified for ZOOM C record update.
898 Allow waitAction to be specified for ZOOM C based for Extended Services.
900 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
901 syntax OID. Bug introduced in YAZ 3 series.
903 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
907 Fixed bug #1157: yaz-client does not read .yazclientrc from current
908 directory. yaz-client now reads commands from file given by option -f
909 if specified; then tries to read .yazclientrc in current directory.
910 Failing that, it reads .yazclientrc from user's home directory.
912 Added support for correlationInfo Note and ID for Record Update via
915 Added yaz-client command querycharset which specifies character set for
916 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
917 (termListAndStartPoint).
919 Charset ISO5428:1984 is an alias for ISO5428-1984.
921 Implemented a way to perform scan in a result set using Z39.50. This
922 is achieved by attaching the result set name in the characterInfo
923 (type InternationalString) of OtherInformation in the Scan Request PDU.
924 The result set is identified in the otherinformation by the new OID:
925 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
926 This allows for scan in result set and faceted search . Zebra did some
927 of this in the APT term using attribute type 8 and value being result
928 set. Using the OtherInformation approach for this is cleaner and easier
929 to work with in proxies and the like. This facility can be used in
930 yaz-client using new command setscan which takes a result set as first
931 argument, start position (APT) as second.
933 Changed decoding of SRU XML packed records to deal with servers that
934 have recordData with XML data with multiple root nodes. Also make
935 comparison for recordPacking case insensitive. Again, one server
936 returns "XML" where others return "xml".
938 For SRU responses allow Content-Type application/xml as well as text/xml.
942 Fixed bug in character set conversion of BER strings. Bug introduced
947 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
949 For OID class, use oid_class consistently.
951 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
954 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
955 character set for bibliographic information interchange". By Giannis Kosmas.
957 Added documentation on new OID API.
961 Changes to generic frontend server interface: added new member
962 'query_charset' for bend_initrequest structure. A backend init handler
963 should set this member to its native character set for query terms.
964 When defined, the frontend server logic will announce this character set
965 to a client if the negotiationModel bit is set by the client. All server
966 implementors are encouraged to specify this. If a backend server does not
967 specify this a warning is issued using yaz_log(YLOG_WARN,..).
969 Added CCL utility to remove terms (stop words) from resulting RPN
970 tree. This is handled by functions with prefix ccl_stop_words_ .
972 New ZOOM C option, "rpnCharset", which allows client-side conversion of
973 terms in RPN queries.
975 Clean-up the CCL API. Moved some internal structures from ccl.h to
976 private header cclp.h. Changed ccl_parser_create so that a Bibset must
977 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
978 This is replaced by ccl_parser_find_str which takes a string instead.
980 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
981 libyaz.la is the core of YAZ except the generic frontend server and
982 does not depend on POSIX threads anymore. libyaz_server.la is the
983 generic frontend server facilities and uses POSIX thread functionality
984 if available. The libyaz.la no longer depends on POSIX threads because
985 the number of global structures is limited. NMEM no longer re-uses blocks
986 between threads ; it simply free's memory immediately but allocates in
987 "large" chunks as usual. We don't expect any performance penalties
988 because of this. The yaz_log system is still using a global log_level so
989 caution must be taken when modifying it with yaz_log_init_.. +
990 yaz_log_mask_str. This, however, should not cause any trouble because
991 these functions are called during initialization of application code
992 anyway. `yaz-config --libs server` returns libs for server applications;
993 `yaz-config --libs` returns libs for non-server applications.
995 New OID database - with public definitions in oid_db.h. Removed old OID
996 database including the head oid.h and definitions such as enum oid_value
997 and struct oident. The new OID database uses the same string names as
998 before but the 'protocol' is gone. There are now only two representations
999 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1000 converts from string to OID; functions with prefix yaz_oid_to_string
1001 converts the other way.
1003 Change to emit_term() in CQL-to-PQF query translation: when a term has
1004 the /regexp relation modifier, do not process it for leading and
1005 trailing "^" and "*", which have quite different meanings in regular
1008 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1009 write handlers no longer carries a 'last' parameter. This will make
1010 yaz_iconv flush "less" characters. A flush is performed by call to
1011 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1013 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1014 removed, because function yaz_query_to_wrbuf does the same.
1016 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1017 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1019 Deprecated MARC utility functions removed.
1021 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1024 Branch split: YAZ_2_1_55_branch
1026 --- 2.1.54 2007/03/16
1028 Fix to ZOOM-C so that transparent reconnection is properly handled on
1029 connections that are in asynchronous mode.
1031 Fixed compilation on OpenBSD 4.0.
1033 Large strings in GRS-1 records are now properly displayed in yaz-client.
1035 Added character conversion support for "advancegreek"; based on patch from
1038 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1039 sequence is met. Before the error was not set so it would be unknown.
1041 Adjust yaz-marcdump MARC reader so that it skips until record separator
1044 --- 2.1.52 2007/03/07
1046 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1047 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1048 fd_set structure used as a bitmask for the FDs to be selected on.
1050 Using ACX_PTHREAD macro to check for POSIX threads.
1052 Fixed have-vsnprintf check.
1054 --- 2.1.50 2007/02/23
1056 Fixes for configure on BSD. Bug #900.
1058 Added snprintf/vsnprintf wrappers for systems that don't have
1059 limits (heavens forbid).
1061 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1062 created before all previous tasks were completed and removed from the
1063 task queue, the new task could be removed by a mistake.
1065 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1067 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1069 Fixed bug #832: Problem with MARC/charset in yaz-client.
1071 Fixed bug #668: save command line history for yaz-client.
1073 Fixed bug #830: pkg-config support.
1075 --- 2.1.48 2007/01/23
1077 Extended ZOOM result set options with two options that may be read by
1078 a client: resultSetStatus and presentStatus with values as specified for
1080 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1082 Fixed bug #827: Using SSL fails on Debian etch.
1084 Fixed bug #826: Weird looking chars for set of MARC records.
1086 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1087 that is treated as an ItemOrder with itemRequest being an XML document
1088 external. The value of "doc" is the content.
1090 Extended the GFS search facility. New member of bend_search_rr
1091 'estimated_hit_count' signals that hits is known to be an estmate
1092 (higher or lower than real hit count). New member 'partial_resultset'
1093 signals that the search was partial (hit count is lower or equal than
1094 real hit count). For Z39.50, the information is stored in resultSetStatus
1095 member of SearchResponse APDU. For SRU, the information is signalled
1096 via SRU diagnostic 59: "Result set created with valid partial results
1099 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1101 --- 2.1.46 2007/01/13
1103 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1105 Added ZOOM_connection_peek_event.
1107 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1108 the following new functions:
1109 ZOOM_event_nonblock, ZOOM_connection_process,
1110 ZOOM_connection_get_{socket,mask,timeout},
1111 ZOOM_connection_fire_event_{timeout,socket}.
1112 The existing blocking event handler, ZOOM_event, is a wrapper for the
1113 + blocking ZOOM_event_sys_{poll,select}.
1115 Implemented function ccl_xml_config which parses XML version of CCL
1116 configuration (bug #798).
1118 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1120 Added timings utility (yaz/timing.h)
1122 --- 2.1.44 2007/01/03
1124 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1127 Fixed bug #779: Rotation of apdu.log fails.
1129 Fixed for character set conversions:
1130 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1131 Honor G1 set in MARC-8 decoding.
1133 --- 2.1.42 2006/12/17
1135 Fixed bug #775: char conversion does not handle Alternative UTF-8
1138 Implemented function yaz_marc_read_line which parses MARC line format
1139 records. There is a wealth of formats out there. So far, this function
1140 reads line records produced by yaz_marc_write_line.
1142 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1143 more generic and easier to remember(!) options: -i format and -o format
1144 which specifies input format and output format respectively - where
1145 format is one of "marc", "marcxml", "line", "marcxchange".
1147 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1148 does not print anything except warnings for records.
1150 For yaz-marcdump, added support for MARC split into files (-s) with a given
1153 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1154 spec, at http://www.loc.gov/standards/sru/record-update/
1155 This has changed the binary layout of the following structs:
1156 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1157 bend_update_rr . Patch by Ko van der Sloot.
1159 Added GFS utility function bend_assoc_is_alive which returns 1 if
1160 association is still alive (client is connected); 0 otherwise (client
1161 closed connection). This allows busy servers to stop working for
1164 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1165 been a separate piece of software. This version of ziffy has been modified
1166 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1168 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1170 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1171 Client code may now interrogate options such as "init_opt_sort" to
1172 find out whether the server claims to support various options.
1174 --- 2.1.40 2006/11/27
1176 Added utilities yaz_{set,get}_esn to set/get element set name from
1179 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1180 of YAZ and has been so since YAZ 2.1.10.
1182 Implemented ZOOM_record_error which returns error information for
1183 record (surrogate diagnostic).
1185 --- 2.1.38 2006/10/31
1187 Updates for SRU Update by Ko van der Sloot:
1188 1. Changed name from "operation" to "action"
1189 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1190 versions in the code, marked as 'backward compatible'.
1191 3. Added diagnostics for SRU Update.
1193 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1195 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1197 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1199 For GFS, fixed problem with SRU diagnostic 'First record position out of
1200 range' being issued for 0 hits.
1202 zoomtst10 part of Windows Build.
1204 --- 2.1.36 2006/10/13
1206 Implemented yaz_filepath_comp which splits a path into file path
1207 components (required by Zebra 2.0.3+).
1209 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1210 BSD inspired license until now so this should not have any real impact on
1211 anybody. See http://www.opensource.org/licenses/bsd-license.php
1213 Fixed bug #687: Missing log lines.
1215 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1218 Fixed bug #689: SRU diagnostics to be added.
1220 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1221 whether a connection is idle (no more work do do).
1223 --- 2.1.34 2006/10/04
1225 Change type of optval from long to int for invocation of setsockopt with
1226 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1228 Added support for specifying the max log file size for the Generic
1229 Frontend Server. The size is given with option -r.
1231 --- 2.1.32 2006/09/21
1233 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1235 --- 2.1.30 2006/09/17
1237 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1240 Fixed bug in Generic Frontend Server that could cause a server to stop
1241 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1243 For the generic frontend server, the maximum record size is used as maximum
1244 size of incoming packages (SRU + Z39.50). The value until was previously
1245 only used in Z39.50 Init negotiation and, later, in a session controlled
1246 sizes of records returned. This is controlled using -k option. It can be
1247 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1249 --- 2.1.28 2006/09/04
1251 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1254 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1256 New option for yaz-marcdump -lpos=value which allows setting a portion
1257 of MARC header to a certain value.
1259 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1261 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1262 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1264 --- 2.1.26 2006/08/15
1266 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1269 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1271 --- 2.1.24 2006/08/08
1273 Fixed MARC ISO2709 encoding routines to deal with character set
1276 Minor changes to GFS logging. Database included in search request log
1279 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1280 cached/multiple records.
1282 Shared libraries are built by default on Unix+configure.
1284 Changed cql2pqf transformation to use a different evaluation order. The
1285 new order is: always, relation, structure, position, truncation, index
1286 and relationModifier. Old order was: always, relation, relationModifier,
1287 structure, index, position, truncation. Note that the the latter ones
1288 override former ones for identical attributes.. The new scheme means that
1289 it is possible to override any existing attribute with a relationModifier.
1290 And also that it is possible to override everything for the index rule
1291 (except the ones listed in relationModifier). No order is perfect but this
1292 one, we believe, covers more real cases.. The "always" should have been
1293 called "default", since the attributes there can be overridden with all
1296 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1297 compilation phase, but also for yaz-config --cflags output. This allows
1298 us to have public headers with Libxml2 stuff in them . It should also,
1299 eventually, make Libxml2 checks redundant in packages using YAZ, such
1302 --- 2.1.22 2006/06/15
1304 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1305 stored in uri, message and details.. Previously diagnostics were stored
1306 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1307 compatibility.. but he's probably the only one affected, so.
1309 Added support for CCL, compiled on the client side, in ZOOM-C. This
1310 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1311 input; the resulting query objects can be used for for searching with
1312 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1314 YAZ' configure searches for OpenSSL by default.
1316 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1317 SL_CTX_use_certificate_file. See
1318 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1319 for more info. Thanks to Ko van der Sloot.
1321 --- 2.1.20 2006/06/02
1323 Bug #600: SRU GET, POST support for yaz-client. Introduced
1324 command 'sru' which selects method SOAP/GET/POST.
1326 Allow missingValueAction to be specified for the sortspec string -
1327 function yaz_sort_spec. By default, the missing value action is null.
1328 Use ! to specify "abort". Use = followed by stringvalue to specify default
1331 Ensured that Present-handler (if defined) is called in GFS before any call to
1332 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1333 searchRetrieve requests.
1335 Documentation for YAZ is now based on the Docbook XML/XSLT using
1336 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1337 is no longer depending on jade/openjade or docbook-to-man scripts.
1338 PDF is no longer part of the distribution - but can optionally be
1339 made using DSSSL/jadetex or FOP.
1341 Added retrieval handling support in Generic Frontend Server to support
1342 conversion between MARC/XML as well as XSLTtransforms. See
1343 etc/yazgfs.xml for an example.
1345 Added Authentication support to Generic Frontend Server in SRU
1346 mode. Authentication using HTTP Basic is supported, as is the use
1347 of 'x-username' and 'x-password' parameters in the request itself.
1349 Added support for a new character set MARC8s identical to MARC8 except
1350 that it converts combined characters to single Unicode characters in the
1351 Latin-1 range (when possible).
1353 --- 2.1.18 2006/04/24
1355 ASN.1 compiler 0.4: generates brief Doxygen file header for
1356 generated .h/.c files.
1358 Utility yaz_iconv now supports conversion to MARC-8.
1360 New facilities for the MARC module. The reading - and writing of
1361 content are separate methods for the yaz_marc_t handle. The following
1362 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1363 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1364 format). Write functions have prefix yaz_marc_write_.. The existing
1365 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1366 available. Removed support for OAI-MARC and simplexml (not the
1367 simplexml from PHP5).
1369 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1370 to be returned for this connection.
1372 --- 2.1.16 2006/03/31
1374 Allow multiple languages and charsets to be specified with
1375 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1376 negcharset iso-8859-1,utf-8
1378 Translation of proximity nodes from CQL into PQF now works.
1380 Moved to automake 1.8, 1.9.
1382 Added function yaz_log_set_handler which allows a log handler to be
1383 installed. This handler will be called for all log messages. Output
1384 to file is also produced; but that can be disabled by passing NULL
1385 fname to yaz_log_init_file.
1387 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1389 For SRW (including GFS), accept application/soap+xml as content-type
1392 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1393 produces NO stylesheet reference even if a default stylesheet is specified
1396 --- 2.1.14 2006/03/14
1398 Updated Windows package to include yazd.dll + yazd.lib for the
1399 Development component.
1401 If the environment variable YAZ_LOG is set, then it is used as a
1402 string indicating the default level of logging to use if not
1403 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1404 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1405 used as before. So, for example, to omit warnings from YAZ logging,
1406 export YAZ_LOG=-warn
1408 cql_transform() now map structure and other attributes before indexes,
1409 so that index-specific structures and other attributes can override
1410 defaults. So now a combination of mapping specifications such as:
1412 index.dc.date = 1=date-modified 4=5
1413 does the right thing.
1415 cql_transform() now also respects the "always" mapping specification,
1416 which establishes an initial set of attributes to be used for all
1417 terms except where overridden by more specific attributes associated
1418 with the index, relation or modifier.
1420 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1421 which mode to use; one of "post", "get" or "soap" (SRW, default).
1423 Fixes for yaz_iconv routines: changed trie-based character set conversions
1424 to use only non-negative values for bit fields due to Sun's C compiler not
1425 supporting negative values.
1427 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1428 sequences where not read correctly. Fix by Rustam Usmanov.
1430 Updated win/makefile to use options, settings which makes things
1431 compile with VS C 2005.
1433 --- 2.1.12 2006/02/01
1435 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1437 In ZOOM socket code, use select instead of poll on MacOSX.
1439 ZOOM-C now support client-side compilation of CQL into RPN that is
1440 sent to the server, enabling CQL to be used against all Z39.50
1441 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1442 ZOOM_query object, and submit it using ZOOM_connection_search().
1443 The CQL-to-RPN translation uses a configuration file, the name of
1444 which must be specified in the Connection's "cqlfile" option.
1446 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1447 function, which takes as its start-term parameter a ZOOM_query object
1448 (which may have had either CQL or RPN set into it).
1451 --- 2.1.10 2005/11/29
1453 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1454 GFS to support this as well. Backend handler, bend_srw_update, does the
1455 update work. Code contributed by Ko van der Sloot.
1457 Allow retrieval of Search Result-1 information in ZOOM by the use of
1458 options that are attached to a result set. ZOOM documentation updated
1461 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1462 UTF-8 conversion. Patch by Raj Patel.
1464 Added option -m to GFS to control formatting of timestamps in log file.
1466 Added 'exit' as synonym for 'quit' in yaz-client
1468 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1469 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1470 for the new members. Patch by Ko van der Sloot.
1472 Added support for SRU POST. It is supported for content-type
1473 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1475 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1476 Instead make the library libyaz.la multi-threaded. Threading as a whole
1477 can still be disabled by configure option --disable-threads. Previosly,
1478 with older GLIBCs there were problems with MT libs under Apache. This
1479 has now been fixed a long time ago.
1481 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1484 CQL module modified to be case insensitive for relations/indexes/operations.
1486 Fixed bug in CQL transform code: incorrect value relationModifieder
1489 Added 'show all' command for yaz-client which retrieves all results
1492 Added new yaz-client, xmles, which takes a (private) OID and
1493 a document to be sent as an extended service request.
1495 Describe new yaz-client commands wait_response and set_auto_wait.
1497 Increase TCP/IP listener backlog from 3 (which I am guessing was
1498 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1499 that the socket will queue as many incoming connections as it's able
1500 to handle ongoing connections. In other words, it will never now
1501 refuse a connection that it would be able to handle merely because
1502 it's not got around to accepting() enough of the pending connections
1503 yet. This is the behaviour anyway under Linux, where the listen()
1504 argument is ignored; but not under BSD and on systems such as
1505 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1506 YAZ-based servers should now be uniform across operating systems in
1509 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1510 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1511 This allows yaz-marcdump to read large MARC batches (>2 GB).
1513 Modified all YAZ source files - except the source which is auto-generated
1514 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1517 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1518 corresponding to the existing *_setl() function. These allow option
1519 values containing arbitrary valuues.
1521 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1522 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1523 except that it returns an indicator of whether or not the sort
1524 criterion was accepted (0 for OK, -1 for invalid).
1526 --- 2.1.8 2005/06/07
1528 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1529 MARC output rather than returning "new" buffer.
1531 yaz-client warns about unknown init options.
1533 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1535 --- 2.1.6 2005/05/24
1537 Added support for SRW sort in Generic Frontend Server. Patch
1538 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1539 sortKeys - or NULL if none is provided.
1541 Fixed bug #307: It was impossible to specify indefinite/no timeout
1542 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1545 Added support for multiple languages and charsets to be specified in
1546 ZOOM. Each charset/language is separated by a blank. If negotiation is
1547 in effect in init-response, Option
1548 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1549 Code based on patch by Vasiliy Osadchuk.
1551 Fixed bug #306: infinite recursion that occurred when calling
1552 yaz_log_level_init as the first call (before other log level or
1555 Fixed bug in scan handling in front end server: if preferred-Position-In-
1556 Response was non-present, a NULL pointer referece was performed.
1558 --- 2.1.4 2005/04/26
1560 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1561 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1562 now defined for all those error codes. So instead of putting 109 in
1563 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1564 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1566 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1569 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1571 Program yaz-client now exits and produces an error message if multiple
1572 Z39.50 servers are specified on the command line (none or one allowed
1575 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1578 --- 2.1.2 2005/03/16
1580 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1582 Fixed bug #272: Preserve spacing for CCL terms.
1584 --- 2.1.0 2005/03/14
1586 Added support for virtual hosts and multiple backend servers for
1587 the YAZ frontend server. The configution is XML based and
1588 support specificition of CQL to RPN mappings and explain information.
1589 See section "Virtual Hosts" in the YAZ manual.
1591 Extended OPAC display utility. OPAC display utility renders
1592 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1593 to supplement yaz_marc_decode_wrbuf.
1595 Fixed a bug in MARC decoder that could caused it to crash for some
1596 invalid MARC records. More diagnostics and warnings where added in
1597 XML output (warnings, etc are stored in comments).
1599 --- 2.0.34 2005/02/08
1601 Fixes for UNIX domain sockets. Bug #261.
1603 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1605 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1606 Added yaz_marc_subfield_str which defines subfield lead string which is
1607 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1608 yaz_marc_endline_str which defines end of fields string used in
1609 YAZ_MARC_LINE format. Default string is newline.
1611 Experimental support for MarcXChange. This format can be produced
1612 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1613 http://www.bs.dk/standards/MarcXchange.xsd
1615 Added yaz-client commands scansize that sets maximum number of
1616 entries to be returned by scan.
1618 --- 2.0.32 2005/01/11
1620 Added support for SRW scan in yaz-client and Generic Frontend Server.
1622 * Added whereInList member to SRW Scan Term.
1624 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1626 Fixed NMEM system to return aligned blocks on the smallest boundaries
1627 that are suitably aligned for all possible types on the particular
1628 architecture YAZ is being built for.
1630 --- 2.0.30 2005/01/04
1632 Fixed numerious warnings that was issued with newer versions of GCC.
1634 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1635 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1638 Make YAZ Generic Frontend Server slightly faster.
1640 Enhance (and reduce) logging for Generic Frontend Server.
1642 Revert YAZ log system so that it flushes every write operation
1643 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1645 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1646 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1647 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1648 will effectively disable old definitions.
1650 --- 2.0.28 2004/11/09
1652 Added yaz_log_time_format which specifies log format using
1655 Added yaz_log_module_level which returns mask for a module. Value
1656 is non-zero mask a if module is enabled; zero if disabled.
1658 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1659 in include/yaz/cql.h.
1661 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1663 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1665 Fixed bug #172: RPM builds does not enable SSL.
1667 Doxyfile.in part of dist. Doxyfile generated by configure.
1669 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1670 are given and the corresponding component does not exist.
1672 Extend CCL documentation in YAZ reference. Describe r=r.
1674 --- 2.0.26 2004/10/01
1676 Fixed MARC->MARCXML conversion to properly deal with
1677 fields, subfields, indicators having non-ASCII characters.
1679 Fixed MARC->MARCXML conversion so that ASCII control characters
1680 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1683 Added YAZ GFS support for conversion from Z39.50 surrogate
1684 diagnostics to SRW surrogate diagnostics.
1686 Bug fix: YAZ GFS did not return schema in explainResponse.
1688 --- 2.0.25 2004/09/30
1690 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1691 now converts recordSchema to elementSetName as well as schema URI.
1693 Fixed bug in COMSTACK that prevented HTTP request packages from being
1696 --- 2.0.24 2004/09/29
1698 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1699 does not require white-space before and after the dash in a range, e.g.
1700 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1703 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1704 due to new GCC removing "redundant" code.
1706 Added yaz-client commands scanpos and scanstep that sets preferred
1707 position and step-size for scan.
1709 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1711 Added CCL utility ccl_qual_buf which parses one or more CCL
1712 spec lines in a buffer.
1714 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1715 of name and value - ignoring empty lines and comments.
1717 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1719 Added odr_get_element_path which returns current element path for an
1720 ODR handle. This utility is useful in error handling or user-defined
1723 Added ODR_PRINT utility odr_set_stream which is is a more generic
1724 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1725 to a write function and pointer to close function. The close function - if
1726 non-NULL - will be called during odr_destroy.
1728 Fixed bug in CCL parser where truncation char was not removed from
1729 right side when truncation=both was in effect.
1731 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1734 --- 2.0.23 2004/08/11
1736 Fix buffer overrun in CQL parser when dealing with proximity (%).
1738 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1739 to UTF-8/UCS conversion is now only based on codetables.xml.
1741 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1743 --- 2.0.22 2004/08/06
1745 Add support for more "commit changes" in ZOOM (uses Extended Services).
1747 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1750 Yet another small fix for configure of SSL.
1752 --- 2.0.21 2004/05/14
1754 Fix SSL libs for configure when --with-openssl=DIR is given.
1756 --- 2.0.20 2004/05/10
1758 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1760 SSL comstack now uses yaz.pem certificate file on server side
1761 by default. Certificate filename can be configured by calling
1762 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1764 Fix bug regarding multiple calls to ZOOM_connection_connect.
1766 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1768 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1769 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1771 ZOOM now allows inspection of X509 peer certificate for verification.
1772 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1774 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1775 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1776 as "modular" but it simplifies things.
1778 Added cs_get_peer_certificate to that returns peer X509 PEM.
1780 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1781 NULL if SSL is unavailable.
1783 Documentation about MARC decoding tools.
1785 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1787 --- 2.0.19 2004/03/30
1789 Rename CHANGELOG to NEWS to follow GNU style packing.
1791 Fix bug with missing initialization of member in init_diagnostics.
1792 This bug affects threaded version of GFS server.
1794 --- 2.0.18 2004/03/20
1796 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1799 Ensure zlib.dll is packed with Windows install.
1801 --- 2.0.17 2004/03/17
1803 Fix encoding of xsd:string to use text instead of CDATA.
1805 Fix endless loop in CQL parser with unbalanced ".
1807 Use a more compact way to store MARC-8 conversion tables.
1809 --- 2.0.16 2004/03/16 Debian only
1811 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1814 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1819 --- 2.0.15 2004/03/01
1821 Another fix for decoding of XML packed records.
1823 --- 2.0.14 2004/02/25
1825 Fixes for Chunked encoding. White space not ignored after length spec.
1827 Update NS and use default NS for SRW diagnostic elements.
1829 --- 2.0.13 2004/02/23
1831 Implement ZOOM_resultset_cache_reset which resets record cache.
1833 Implement ZOOM_resultset_sort which sorts a result set.
1835 Implement chunked HTTP transfer.
1837 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1839 --- 2.0.12 2004/02/16
1841 Added member 'schema' to bend_explain_rr structure so that backend
1842 can specify explain record identifier. Defaults to Zeerex 2.0.
1844 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1846 --- 2.0.11 2004/02/16
1848 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1851 Added init command for yaz-client which sends "extra" init request.
1853 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1854 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1856 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1858 Make ZOOM error code for "invalid query".
1860 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1862 --- 2.0.10 2004/02/05
1864 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1867 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1869 Added option -p <file> to make Generic Frontend Server to write PID file.
1871 Added option -D to put Generic Frontend Server in background on its own.
1873 Make ZOOM C recognize option "password". If unset, "pass" is used
1874 (for backwards compatibility).
1876 Fixed a bug in Generic Frontend Server that could make it crash if a
1877 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1880 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1881 Must be issued before open, in order to be in effect.
1883 --- 2.0.9-6 2004/01/12 Debian/Windows
1885 Make the SRU server more picky WRT unknown params, etc.
1887 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1889 New YAZ client command, options, that sets Z39.50 options.
1891 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1892 options from a string of tokens (one token for each option bit).
1894 Update SRW diagnostic code messages.
1896 --- 2.0.9-5 2004/01/07 Debian/Windows
1898 Handle user defined stylesheet for SRW/SRU.
1900 --- 2.0.9-4 2004/01/06 Debian/Windows
1902 Fix bug in decoding of Content-Length.
1904 --- 2.0.9-3 2004/01/06 Debian/Windows
1906 Fix a bug with decoding of XML packed records.
1908 --- 2.0.9-2 2004/01/05 Debian only
1910 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1912 Fix bug in SRW/SRU diagnostics decoding.
1914 --- 2.0.9 2004/01/05
1916 Fixed bug in Generic Frontend Server which could drop records exceeding
1917 preferred message size. Reported and fixed by Irina Dijour.
1919 Fixed calculation of package size for structured records in Generic
1920 Frontend Server. Reported and fixed by Irina Dijour.
1922 Fixed namespace for SRW/SRU diagnostics.
1924 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1926 --- 2.0.8 2003/12/22
1928 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1929 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1932 CQL changes to reflect recent changes to the specification:
1933 * Documentation talks about context sets instead of index sets.
1934 * Documentation talks about indexes instead of qualifiers.
1935 * The CQL-to-PQF transformer's configuration file now uses
1936 "index.set.name = <attributes>" instead of the old form
1937 "qualifier.set.name = <attributes>". (Both forms are still
1938 understood but the latter is deprecated.)
1939 * CQL terms with no explicit index specified are now interpreted as
1940 cql.serverChoice instead of srw.serverChoice (which of course
1941 behaves exactly the same.)
1943 --- 2.0.7 2003/12/16
1945 MARC conversion can now generate ISO2709 output in another
1946 character set. yaz-marcdump uses this facility if you invoke it
1949 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1950 functions from there can be used from C++.
1952 --- 2.0.6 2003/12/04
1954 Frontend server now transfers memory from decoded packages to stream
1957 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1958 references to show up.
1960 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1961 the ZOOM Abstract API. The older names for the same options are still
1962 also supported for the benefit of old applications.
1964 ZOOM-C supports "implementationId" and "implementationVersion" options
1965 to go along with "implementationName". These allow the user code to
1966 specify identification strings to be sent to servers.
1967 Add OID for the new ExtLite attribute set.
1969 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1970 as requested/supplid by Ere Maijala <ere@atp.fi>
1972 For generic frontend server, reverse the order of
1973 "toolkit-supplied / application-supplied" strings sent as implementationId,
1974 Name and Version. Also, remove the spaces around the slash. This brings
1975 the GFS in line with the behaviour of ZOOM-C on the client side.
1977 Add function ZOOM_scanset_display_term.
1979 yaz-client shows scan displayTerm if present.
1981 Utility yaz-iconv is now installed by default along with the man page
1984 Extend configure check for OpenSSL to use pkg-config where available (such
1987 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1988 server to specify uid/gid/mask for socket using the format
1989 unix:[user=uid,][group=gid,][umask=mask,]file=path
1990 If file= is omitted the existing format is assumed, e.g.
1992 in which case the mask is 0666 (rw for everybody).
1994 Major restructure of YAZ source. All source in libyaz is in src directory.
1995 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1996 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1998 Added man page for utility yaz-marcdump (used to be called marcdump).
1999 yaz-marcdump is installed by 'make install'.
2001 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2002 of incoming package failed.
2004 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2006 Change prototype of odr_perror: add const to message string.
2008 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2010 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2011 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2012 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2013 DNS lookup. There should not be any compatibility problems with this
2014 assuming that blocking=1 or 0 is used.
2016 Fix bad reference in UNIX comstack in function cs_addrstr.
2018 Fix for compilation on AIX.
2020 The generic front-end server (server/seshigh.c) now supports returning
2021 Init diagnostics to the client in User-information-field, in
2022 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2025 --- 2.0.4 2003/09/04
2027 Allow any CQL relation (not just all,any,exact,scr).
2029 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2030 that features the same UI.
2032 Implemented command update0 in YAZ client which is equivalent to
2033 update but uses old of Ext Update ASN.1.
2035 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2036 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2037 Previously no OID was used for this info.
2039 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2040 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2041 returns 'malformed search term' otherwise.
2043 SortResponse member resultCount now set to NULL in sort handler of
2046 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2049 Add three new utility functions for translating OIDs between various
2050 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2051 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2052 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2053 char *oid_to_dotstring(const int *oid, char *oidbuf);
2054 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2056 Reverted modifications for ES Update definition for z_IU0Update
2057 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2058 is back to YAZ 2.0.2.
2060 String value attributes for CCL parser.
2062 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2063 which their FirstSearch server returns in Init responses, sometimes
2064 carrying useful diagnostic information when Init fails. This has the
2065 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2066 "z39.50/oclcui.asn", where its definition is somewhat different from
2067 what OCLC document on their web-site, as required to interoperate with
2070 Support for anonymous authentication in yaz-client. Use the command
2073 * Fix the OID of the Index Data-local "admin" Extended Service from
2074 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2075 the 1000, which indicates a locally-defined OID, was a mistake.
2077 --- 2.0.3 2003/06/20
2079 Fix CCL directive @case handling so that it affects string match for
2080 both CCL keywords and qualifiers.
2082 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2083 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2084 Decoder has been updated with ASN.1 changes as listed in
2085 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2086 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2087 z_IUUpdate, remains unchanged.
2089 ZOOM_record_get may now return a record in a specific character set.
2090 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2091 "from" is the character set of record as returned by target. "to" is
2092 the character set to be returned. If omitted, "to" is UTF-8.
2094 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2096 New ODR utility, odr_getelement, which returns name of element for
2097 which encoding/decoding failed.
2099 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2100 in cases where a required element was omitted.
2102 Bug fix: some MARC8 sequences were not converted.
2104 New ZOOM option "step" which specifies number of records to be
2105 retrieved in one chunk. Used in conjunction with "start" and "count".
2107 SRW support for yaz-client. Use scheme http: to use it, e.g.
2110 yaz-client no longer does (un)intelligent character set conversions
2111 by default. Can be enabled with charset and marc_charset commands.
2113 xmalloc trace fix for 64-bit systems such as DEC alpha.
2115 Solaris 2.6 compile fix.
2117 New function, cql_strerror() translates SRW error codes, as returned
2118 by cql_transform_error(), into human-readable English strings. Used
2119 in yaz-client diagnostics when appropriate.
2121 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2122 converts it into a type-1 query which is sent to the server. This
2123 makes CQL available for use with all Z-servers, as opposed to the tiny
2124 minority that can handle CQL queries themselves.
2126 --- 2.0.2 2003/04/28
2128 New Debian package layout similar to the Redhat Package layout.
2130 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2131 and search result respectively.
2133 --- 2.0.1 2003/04/25
2135 Redhat package is now several packages: libyaz (runtime libraries),
2136 libyaz-devel (development and documentation, and yaz (utility programs).
2137 Package spec file by Morten Bogeskov.
2139 New member 'schema' in struct bend_fetch_rr which the name of requested
2140 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2141 handler MAY set this to reflect the schema of the returned record.
2143 New member 'display_term' in struct scan_entry. GFS now sets member entries
2144 and allocates scan entries to be filled by user scan handler. In previous
2145 version, entries member was allocated by the scan handler. That still works,
2146 but the GFS will ignore member display_term - assuming it was NOT set by
2147 the handler. The fact that the GFS now allocates the entries both allows
2148 for new members and makes a scan handler easier to write.
2150 Fix CQL lex buffer overflow.
2152 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2153 SRU default recordPacking is string.
2155 SRU protocol support for frontend server.
2157 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2159 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2161 Added scan for the ZOOM shell (zoomsh).
2165 * String Identifers for Schemas (Amendment 5).
2166 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2167 Old definition for schema
2168 Odr_oid *schema; /* OPT */
2173 Z_InternationalString *uri;
2174 #define Z_Schema_oid 1
2175 #define Z_Schema_uri 2
2178 * resultCount parameter to Sort Response (Amendment 1).
2179 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2181 Support for SRW 1.0 over HTTP. This is an optional feature and
2182 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2185 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2186 on the same port. SRW SearchRetrieveRequests are mapped
2187 to bend_init,bend_search,bend_fetch,bend_close.
2189 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2191 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2192 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2194 ZOOM connections are SRW based if schem http is used for hostname
2195 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2196 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2198 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2199 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2200 distance=n, order=true/false, relation=le, prox unit=word. If
2201 n is omitted, distance 1 is used.
2203 Fixed problem with C compiler include path in wrong order.
2205 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2206 on Solaris. Patch from Ko van der Sloot.
2208 New MARC decode API. All new functions operate on a yaz_marc_t
2209 handle. The most important new functions are: yaz_marc_create,
2210 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2211 decode and destroy respectively. Decoder can produce formats
2212 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2213 include/yaz/marcdisp.h.
2215 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2216 to UTF-8, UCS-32, wchar_t or Latin-1.
2218 * Prototypes for yaz_iconv_-functions moved to separate header
2219 include/yaz/yaz-iconv.h.
2221 Make a few private functions 'static' in unix.c. This prevents
2222 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2224 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2225 are set when Init Response is received.
2227 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2228 but returns diagnostic set as well.
2230 New function yaz_strerror which is a portable wrapper for
2231 strerror/strerror_r/GetLastMessage.
2233 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2234 is returned for MARC. If type is "oai", then OAI MARC is returned.
2236 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2239 --- 1.9.2 2002/11/26
2241 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2243 Fix bad race conditions on SIGTERM and terminate gracefully in
2246 Move retrieval (data1) module to Zebra since nobody seems to be
2249 Add GRS-1 render for ZOOM using same format as yaz-client.
2251 --- 1.9.1 2002/10/05
2253 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2255 Fix broken ESpec handling in data1 module.
2257 SGML reader parses comments and makes them part of the data1 tree.
2259 Added several type casts so that YAZ compiles as C++ code.
2261 ZOOM didn't handle PDU encoding failures properly.
2263 Added more Bib-1 diagnostics (approved extensions).
2265 GNU configure: better check for iconv.
2267 More portable use of accept, getpeername. Check for socklen_t. Use
2268 int/size_t if socklen_t is not defined.
2272 PQF parser rejects bad queries - including those with extra
2273 characters in them. PQF parser used to silently ignore that.
2274 Cleaner API for PQF added, which allows you to get detailed
2275 error information for bad queries (see yaz/pquery.h).
2277 Fixed bug in ZOOM_record_get for type "database".
2279 Implemented mini iconv library supporting conversions between
2280 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2282 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2284 --- 1.8.9 2002/08/20
2286 Fixed ZOOM C record cache so that preferredRecordSyntax and
2287 elementSetName is used to check for already fetched records.
2289 --- 1.8.8 2002/08/02
2291 Added three members in bend_initrequest structure to facilitate
2292 character set negotiation.
2294 Fixed a bug in frontend server that could cause indefinite
2295 loops under rare conditions.
2297 Revised character set utilities (charneg.h) so that encoding
2298 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2300 For PQF, directive @term <type> sets term type for Scan/Search.
2301 Here <type> is general, string, numeric, null. The term type
2302 is inherited - just like @attr.
2304 New call odr_set_charset that sets character set conversion for
2305 international-strings on a ODR stream. Prototype is:
2306 int odr_set_charset(ODR o, const char *to, const char *from);
2307 The InternationalString is still represented as C string in YAZ
2308 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2309 won't). On the protocol level, you can use any encoding.
2311 Support for UNIX sockets in ZOOM.
2313 Solaris recv sometimes returns errno == ENOENT. It is treated as
2314 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2316 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2317 both client and server. Code by Morten Bogeskov.
2319 --- 1.8.7 2002/05/22
2321 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2322 that they can be used directly from Visual Basic. You must recompile
2323 your windows APP if you're using ZOOM.
2325 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2326 Commands "lang" and "charset" sets language and character set respectively.
2327 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2328 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2330 Attributes from multiple CCL fields may be OR'ed rather than merged
2331 using directive "@field or". Fields are still merged by default -
2332 equivalent to "@field merge".
2334 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2337 Fixed bug in zget for parameter ExtendedServicesResponse.
2341 --- 1.8.6 2002/03/25
2343 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2345 Client displays USR.1:SearchResult-1 (hits per term).
2347 Additional Search Info for search in Generic Frontend Server.
2349 Fixed CCL parsing of "field=s".
2351 WIN32 installer - using the excellent NSIS software from nullsoft.
2353 Fixed CCL parsing of "field = - <number>".
2355 Added function yaz_marc_decode that decodes MARC for line mode
2356 display or XML (similar to that used by JZKit).
2358 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2359 Z39.50. But ISO/ILL was, however.
2361 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2362 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2364 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2365 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2367 --- 1.8.5 2002/02/03
2369 New YAZ client features: Command completion and new commands:
2370 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2371 Code provided by Jacob Poulsen.
2373 New call oid_trav, that visits all registered OIDs via callback.
2375 Function ZOOM_record_get now returns const char pointer rather than
2376 void pointer. It saves a lot of type casts.
2378 For YAZ client, command "auth" now allows you to set authentication
2379 in IdPass style. It is enabled when three tokens are given - order
2380 is user, group and password.
2382 Fix memory leaks in MARC record handling for ZOOM.
2384 New option for YAZ client, -k <kilobytes> that sets
2385 maximum record size. Similar to -k option for generic frontend
2386 server and yaz-ztest.
2388 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2390 Prefix query parser reports "fail" when bad attribute set is given.
2392 Fix in MARC decoder. Proximity logging. Fix for attribute set
2393 in scan handler for server. Patches by Shigeru Ishida.
2395 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2398 Configure option --with-openssl=<dir> now works when a directory is
2399 specified. Patch provided by Morten Bogeskov.
2401 New option for YAZ client, -u <auth>, that sets authentication.
2403 ZOOM fix: error information was sometimes "missing", since error
2404 was cleared/reset too when it shouldn't.
2406 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2408 --- 1.8.4 2002/01/04
2410 Scan for ZOOM API. New object ZOOM_scanset. New functions
2411 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2412 ZOOM_scanset_destroy.
2414 New ZOOM function, ZOOM_connection_last_event, that returns type
2415 of last event (such as "receive data", "send data", "apdu received",
2418 New ZOOM option, schema, that specifies schema for retrieval.
2420 New CCL feature. Qualifiers can be aliases for one or more
2421 other qualifiers (if more than one is given, OR is used).
2423 ZOOM uses named result sets if target supports it.
2425 Two new YAZ client commands: . (dot, which sources a script of YAZ
2426 client commands), and ! (to execute shell command.). Implemented
2429 Working on Debian packages.
2431 --- 1.8.3 2001/11/19
2433 YAZ client enables named result sets only if target supports it.
2435 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2437 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2438 with key="host" to get same result.
2440 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2441 Function Z3950_resultset_record(s) returns references to records
2442 "owned" by resultset. To become owner use Z3950_record_clone.
2444 Function z_ext_record handles Extended Services. Thanks to
2447 --- 1.8.2 2001/11/12
2449 CCL Parser fix: ignore token comma when dealing with and-lists.
2451 Documentation updates for COMSTACK.
2453 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2454 Changed prototype Z3950_records. For some functions, int parameters
2455 were changed to size_t.
2457 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2460 New MARC decode/display function, marc_display_exl, which properly rejects
2461 non-ISO2709 records. YAZ client uses it.
2463 --- 1.8.1 2001/10/29
2465 Fix bug: local attribute set wasn't set correctly in PQF strings.
2469 * Old Z39.50 codecs no longer supported.
2471 Added ZOOM C binding. See http://zoom.z3950.org/
2473 Renamed states for COMSTACKs to avoid confusion with events.
2475 Implemented cs_look and proper cs_rcvconnect.
2477 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2479 Configure detects POSIX threads on OpenBSD.
2481 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2482 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2484 When error is returned from present handler, non-surrogate diagnostic
2485 is returned in present response (and fetch handler is no longer called).
2487 * Minor adjustments to pquery parser (PQF). Token characters may be
2488 escaped by using backslash (C-style).
2490 PQF parser allows string attribute values to be specified. For @attr,
2491 non-numeric characters after the equal-sign are treated as strings
2492 (e.g. @attr 9=title).
2494 CCL trunction character may be defined (@truncation in file)
2496 * function zget_ExtendedServicesRequest sets waitAction to
2497 waitIfPossible (was wait).
2499 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2502 CCL operator names may be set in field definition files (CCL_bibset).
2503 See ccl/bib1 for an example.
2505 Fixes in ASN.1 compiler for C++ compatibility.
2507 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2508 and "op_or" to avoid conflict with C++.
2510 Fixed problem with GNU readline detection on Redhat 7.0.
2512 Added step-size for Scan backend handler.
2514 Fixed bug that made the frontend server crash when no attribute
2515 set was specified for scan.
2517 Front-end server automatically switches to original working directory
2518 when installed as an NT service. Previously -w had to be specified to
2521 Added extended attributes for retrieval module (data1), so that data1
2522 records carry d1_readXML/SGML attributes. d1_read also supports
2523 null-data rules ( <tag/>)
2525 On UNIX when POSIX threads are available, a separate library libyazthread
2526 is created. Programmers should link with that library and the yaz library
2527 when using threads. The reason for the split was that some applications
2528 on Linux, such as Apache, doesn't work well when using shared objects that
2531 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2532 (or any frontend server) in SSL mode by specifying ssl: followed by
2533 address. Only tested on UNIX.
2535 Added feature for CCL module. Virtual structure s=al or s=ol generates
2536 and-list and or-list respectively instead of phrase search.
2540 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2541 log_mask_str. This was done to avoid name conflicts with other libraries
2542 (such as other PHP extensions).
2544 Added raw OID member for preferred record syntax (request_format_raw)
2545 and returned record syntax (output_format_raw) for backend fetch method.
2547 Config file yaz-config now accepts options so that it returns specific
2548 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2550 Shared library support for UNIX using GNU libtool.
2552 * Modified backend interface. Request/Response struct's replaced by
2553 one read/write C struct. For example bend_fetchrequest and
2554 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2555 Every handler - even search has to be registered in bend_init
2556 handler. This means that the YAZ library no longer refers to
2557 external functions and it makes it possible to make the whole
2558 thing a single DLL/SO.
2560 Added Segment handler for backend server.
2562 Added Zmbol/Zebra administrative functions to YAZ client.
2564 Threaded frontend server on UNIX (when POSIX Threads are available).
2565 Starting the server with option -T enables multi-threading.
2569 Added configure option --enable-comp/disable-comp to control use
2570 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2571 located in sub directory asn.
2573 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2574 in ${exec_prefix}/bin along with the other programs yaz-client and
2577 GNU automake used to maintain makefiles.
2579 Added several OID's.
2581 Changed retrieval module so that we can load records with no abstract
2582 syntax defined. Tagpaths in these records are fully composed of string
2585 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2589 On UNIX, the generated makefile now supports a proper 'make install'.
2590 The prefix can be set via GNU configure to set the install location
2591 (default is /usr/local).
2593 * YAZ programs client and ztest were renamed to yaz-client and
2594 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2595 locations, such as /usr/bin,/usr/local/bin,etc.
2597 * YAZ Header files were moved from include to include/yaz. YAZ Header
2598 files are referred to as include <yaz/log.h> rather than <log.h>.
2599 The YAZ include path (-I ..) is therefore the same as before. Programmers
2600 should update their #include statements or use -Ipath/include/yaz
2601 instead. The main motivation for doing this change is that YAZ header files
2602 can be installed in "standard" locations /usr/include,/usr/local/include
2603 without introducing conflicts, since ALL YAZ header files are stored
2604 in subdirectory yaz (under /usr/include for example).
2606 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2607 rather than project/workspace files. We switched because project files
2608 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2611 Changed name of logging function, logf, to yaz_log, to prevent name
2612 clash with some math-log functions. The YAZ header log.h defines logf
2613 to yaz_log (#define) so there should be no incompatibilities by this
2616 Added bend_start/bend_stop handlers for server. These handler are
2617 called on start/stop of server. For windows they are called whenever
2618 a service is started/stopped.
2620 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2621 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2622 in util/yc.tcl. The auto-generated C code structures are, in a few
2623 cases, incompatible with the old decoders. There are differences in the
2624 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2625 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2626 The preprocessor variable ASN_COMPILED is defined when the compiled
2627 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2628 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2629 wish to use the old encoders/decoders you can specify --disable-yc
2632 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2633 version so that it supports both new - and old version of DB Update
2635 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2636 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2637 change. The name parameter can be set to 0 in which no name is specified
2638 for the construction. The macros odr_implicit and odr_explicit sets name
2639 parameter to zero for the construction involved. New macros
2640 odr_implicit_tag and odr_explicit_tag are similar to the others,
2641 except that a name parameter is added. For programmers' that don't use
2642 ODR they probably only need to change the call to z_APDU and z_External.
2644 Added access control facility by interfacing the TCP wrapper library.
2645 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2646 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2647 name of the daemon and enables the access control as specified in
2648 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2650 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2651 den Dool <H.M.vdnDool@kub.nl>.
2653 Added reference ID parameter to most functions in server API - refer
2654 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2656 Changed name of ccl library to libccl.a (was ccl.a).
2658 Fixed bug in decoder for Explain (Category TargetInfo).
2660 Added support for GNU readline in client. Thanks to Jacob Poulsen
2661 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2663 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2664 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2665 IMPLEMENTATION! This change was made to the development version before
2666 the ZIG decided to retract the amendment. If any users MUST be
2667 compatible with the original Update definition, PLEASE CONTACT US, and
2668 we will include a separate definition corresponding to the old Update
2669 ES. Note that because of the change to the ASN.1 of the
2670 TaskPackageRecordStructure we cannot define a single structure that
2671 will support both versions.
2673 * Added const modifier to buffer parameter for some ODR/BER encoding
2674 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2675 completeWAIS, odr_dumpBER.
2677 Fixed bug in client.c which caused a crash when a scanResponse didn't
2678 contain positionOfTerm.
2680 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2681 * will cause an error in a client if a non-YAZ target sends both a
2682 * list of Scan entries and non-surrogate diagnostics.
2684 Retrieval module enhancements. Tag sets may be typed in the reference
2685 to it. From the .abs-file the "tagset" directive takes a third optional
2686 integer type for the tag set referenced. From a .tag-file the "include"
2687 directive takes a third optional type as well. The old "type" directive
2688 in the tag set itself is still recognized but acts as the default type
2691 Backend interface change. Individual Scan terms returned from bend_scan
2692 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2693 in include/backend.h.
2695 Retrieval module enhancements. Multiple tag sets and attribute sets may
2696 be specified in abstract syntax specs. Revised the error/warning for
2697 logging messages reported by the retrieval module when reading the
2700 Object Identifier system (oid_..) changed. The API is backwards
2701 compatible but the oid-routines now allocates new OID's when needed.
2702 Raw OID's may be specified in oid_getvalbyname.
2704 YAZ now uses GNU configure to generate Makefile(s).
2706 * Minor changes in some of the member names of DeleteResultSetRequest and
2707 DeleteResultSetResponse. See include/proto.h.
2709 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2710 and added member 'languages' in TargetInfo (which was missing).
2712 Changed the way attribute sets are handled in the retrieval
2713 module. These are now cached, just like the abstract syntaxes
2716 Changed YAZ so that it links with compiled ASN.1.
2718 Added Explain-schema definitions and mapping routines. The following
2719 Explain categories have been implemented: AttributeDetails,
2720 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2722 Fixed minor bug in Windows version of Server Library.
2724 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2726 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2728 Added EXTERNAL: UNIverse Resource Report (non-standard).
2730 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2731 ENUMERATED and SET OF.
2733 * Added 'const' to some of the char pointer arguments for the
2734 functions, data1_read_node, data1_getelementbytagname,
2735 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2738 Fixed bug in data1_insert_taggeddata - the last_child member of
2739 parent wasn't initialised.
2741 * Changed data1_read_record and data1_read_node so that the supplied
2742 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2743 doesn't refer to any parts of the "SGML"-buffer.
2745 Fixed bug in server library (Windows version of statserv_remove).
2747 * Changed code so that it compiles as C++. The type definition
2748 of Odr_fun which is a member of Odr_arm was changed. The result is,
2749 that an explicit typecast is needed for the fun pointer when
2750 using Odr_arm - as in:
2751 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2753 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2755 Implemented the new structured date and time definition as approved
2756 by the ZIG. Added schemaId element to the specificTag in Espec-1
2757 (also approved at the last ZIG). Thanks to RVDM.
2759 Added some Object identifiers (RVDM).
2761 Changed the Update Extended Service (RVDM).
2763 Added command "refid" to client which specifies referenceId for
2764 the following requests.
2766 Implemented extended service handling for server. See ztest.c
2767 for an example as well as backend.h. New handlers are registerd
2768 in the Init handler.
2770 * Changed interface for sort in server.
2772 Added new members to statserv_options_block. It allows a server
2773 to read options from another source than just the command line. Thanks
2774 to Charles Woodfield.
2776 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2777 renamed to zboolean. Some C++ compilers complained about the name.
2779 Minor changes to gils.abs. Added index 's' (sort) on title
2780 and date/time-last-modified.
2782 --- 1.4pl2 1998/1/30
2784 Fixed bug in server library regarding inetd mode (-i). This bug
2785 was introduced by release 1.4.
2787 --- 1.4pl1 1998/1/29
2789 Added sort facility in client and backend server interface.
2791 Fixed problem with dependencies in Makefile(s).
2793 Fixed bugs for encoders/decoders of extended services and
2796 Implemented sub-tree feature for schemas. Sub-trees are
2797 referenced in *.abs-files. See explain.abs for an example
2798 of the use of this feature.
2800 Modified bib1.att; local attributes for ANY didn't include
2801 ANY itself (only affects use of the retrieval module).
2803 Fixed bug in plain SGML reader in function data1_read_node:
2804 tags with prefix "var" was incorrectly interpreted as variants.
2806 Added feature "sub-schemas" to enable references to - and definitions
2807 of - group of elements.
2809 * Removed member parent from type data1_element (in data1.h).
2811 Implemented function odr_nullval() that returns the value of
2814 * Removed member num_children from data1_node (in data1.h).
2816 Made NT service interface part of the server library. The
2817 function statserv_main uses the NT service when required and
2818 calls the statserv_start / statserv_close routines.
2820 Routine zget_SearchRequest and zget_PresentRequest fills
2821 resultSetName/Id member with "default" instead of "Default".
2823 Fixed memory leak in server. Request queue member wasn't freed.
2825 Fixed nmem_exit so that memory is freed.
2829 Revised the CCL parser utility to be thread safe.
2831 Added function, oid_ent_to_oid, to replace the function
2832 oid_getoidbyent, which is not thread safe.
2834 * Added nmem_init and nmem_exit to initialize and release
2835 NMEM resources. Function nmem_init should be called once in the
2836 initial thread before NMEM/ODR is used. statserv.c and client.c
2837 have been changed accordingly. The change was necessary to make
2838 NMEM thread safe. The NMEM memory pool is shared amongst threads
2839 in a process. Unix-based applications will still work fine without
2842 Added NT Services interface for the the Z39.50 (statserv) Server.
2843 Refer to the ztest.c source on the usage.
2845 Windows 95/NT port using MSVC5.0. Project files are included in the
2848 * Defined new 'global' handle for the retrieval (data1) system. The
2849 new handled, data1_handle, describes the state of the data1 system.
2850 This handle is passed as first argument to virtually all
2851 data1 related routines. The functions data1_create and data1_destroy
2852 creates and destroys a data1 handle respectively.
2854 Added ODR encode stream member to all backend request structures
2855 init, search, scan etc. This stream should be used to allocate all
2856 memory used for the response when thread safe operation is needed.
2858 Changed the comstack utility, cs_addstr, to be thread safe. The
2859 returned hostname string returned by the function is now part the
2862 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2863 function. The cs_straddr takes a COMSTACK handle as argument, so this
2864 function must be used after cs_create and before bind/connect.
2865 This function is thread safe.
2867 Moved test server to 'ztest' directory - generic server code still
2868 in 'server' directory.
2870 Made prefix query (pquery.c) utility thread safe.
2872 Added new function modifier YAZ_EXPORT to 'export' public DLL
2873 functions when using windows (see include/yconfig.h).
2875 Added definitions to the OID database (util/oid.c) (RVDM).
2877 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2879 Added call to ccl_rpn_delete in client program.
2881 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2882 release of RPN structure.
2884 Added support for C++, headers uses extern "C" for public definitions.
2885 With input from RVDM.
2887 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2888 Thanks to Ronald van der Meer (RVDM).
2890 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2892 Added support for private extensions to the OID database
2893 (oid_setprivateoids()). Thanks to RVDM.
2895 Added optional, physical ANY (key replication)
2897 Fixed null-reference problem in GRS-1 output filter.
2899 Proximity operator added to Prefix Query Format (PQF).
2901 In test client command "base" accepts multiple databases.
2903 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2907 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2909 Smallish bug-fixes in the new encoders/decoders (explain).
2911 Bug fixed in DeleteRequest.
2913 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2915 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2917 Added SOIF syntax (using private OID for now) to retrieval module and client.
2919 Added Update extended service.
2921 Added SearchResult-1 additional info structure.
2923 Added optional CCL (ISO8777) interpreter as separate module. Available
2926 --- 1.2 1996/6/10 (1st anniversary release)
2928 Added Summary record syntax. Lightly tested.
2930 Added OPAC record syntax. Untested.
2932 Added ResourceReport service encoders/decoders. Untested.
2934 Fixed bug in z_Unit - wrong tagging on unitSystem.
2936 Fixed bug in the DiagRecs decoder.
2938 Added options for max PDU size and session timeout to frontend-server.
2940 Added documentation of query-language parsers and other supporting utilities.
2942 [frontend-server] Added Attribute set to the bend_scanrequest API.
2944 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2945 surrogate diagnostics were generated.
2947 [retrieval] Allow multiple local values for attribute.
2949 [retrieval] Allow multiple attributes per element in .abs files. index type.
2951 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2953 --- 1.1pl2 1996/4/10
2955 Minor changes, mostly specific to Zebra's requirements (retrieval)
2959 Repaired bug in frontend server when running multiple listening
2960 endpoints in dynamic mode.
2962 z_External() now won't break if a known, ASN.1 value comes encapsulated
2963 in an octet-string. The value will pass through unmodified in an Odr_oct.
2965 Added a bit of code to the demo client to decode & display
2966 ASN.1-structured records represented in the octet-aligned branch of
2967 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2969 Added z_ext_getentbyref() to the ASN module. Doc updated.
2971 * Completed the SCAN definition in the ASN module. This may break SCAN
2972 code based on older YAZ-versions at compile-time. The fix is easy -
2975 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2976 under the SCAN definition. Remember to initialize this, server-people.
2978 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2979 that this does not extend to ODR and ASN.
2981 Comstack allows insertion of established socket (primarily for
2982 inetd-operation of servers). Doc updated.
2984 Front-end server can now start from the inetd in TCP mode. Doc
2987 --- 1.0pl4 1996/1/24
2991 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2992 the rank and record number.
2994 Adjustments to the frontend server.
2996 Fixed diagnostic BER dumper. It ignored the file argument.
3000 Various changes to retrieval module.
3002 Changed the union discriminators of the protocol files from enums to
3003 ints paired with #defines.
3005 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3008 *Changed operator in the RPN structure to 'roperator', again to avoid a
3011 Fixed problems in Explain decoders/encoders.
3013 --- 1.0pl2 1995/12/6
3015 Memory bug in log module fixed.
3017 --- 1.0pl1 1995/12/5
3019 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3021 Bug in Explain DatabaseInfo module fixed.
3023 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3027 The shift to v1.0 signals that we now consider the *core* functionality
3028 of YAZ reasonably stable (the core being more or less equivalent to
3029 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3030 tested (Explain not at all - though that will happen soonish).
3032 Minor changes to code to support Windows port.
3034 Various minor changes after we're getting to use GRS-1 & co. more.
3036 Added Espec-1 format.
3038 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3039 of the protocol and it cannot be selected when encoding (maps into 'string'
3040 when decoding). Needed to talk to some servers.
3042 Demo client can request simple element set names.
3044 Added Diagnostic Format encoders/decoders.
3046 Added simple Close handling to frontend server (no hooks for resource
3047 reporting yet), and demonstration client.
3049 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3051 --- 1.0b3 1995/08/24
3053 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3054 handled incorrectly when records were requested in the searchResponse. This
3055 will only affect you if you use the frontend-server.
3057 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3058 Test-client will ask for and print GRS1. Ztest will return dummy records
3061 Added Explain encoders/decoders to the service-level API. Untested.
3063 Added Extended Services: Item Order encoders and decoders to the Service-
3064 level API. Untested. We could use a recent copy of the pertinent bits
3065 of the ILL protocol to add those bits.
3067 Added diagnostic format 1 encoders/decoders to the service-level API.
3070 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3071 odr_cons.c, which causes a more correct output.
3073 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3074 was always set to 0 when no records were requested in the searchRequest.
3076 * Added better external-handling. This shouldn't harm old code that
3077 *encodes* externals. It can break code that looks for a
3078 'single-ASN1-type' representation, since those types that are known
3079 are now decoded immediately. Look at the SUTRS sample code in
3080 seshigh.c and client.c. Documentation updated.
3082 Handling of structured records in bend_fetchresponse. Length -1 marks
3083 structured record, type is deduced from format field.
3085 --- 1.0b2 1995/06/27
3086 Fairly quick maintenance release to add SUTRS support.
3088 Fixed handling of SUTRS records in the demonstration client.
3090 * Added format field to the bend_fetchrequest and bend_fetchresponce
3091 structures of the backend API (frontend server). When the record is
3092 returned, the value of the format field is mapped to an OID. The
3093 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3094 of the record. The special value VAL_NONE in the bend_request means
3095 that no specific format was requested by the client. Documentation
3096 updated accordingly. Test server (ztest) will return a fixed dummy
3097 SUTRS record if your client requests SUTRS.
3099 Documentation updated accordingly.
3101 You can now set external libraries and RANLIB support in the top-level
3105 First public release.
