1 record_conv: modify new API for conversion types. The conversion types
2 may be passed in new functions yaz_record_conv_configure_t and
3 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
5 Avoid mixed statement/variable declare; fixes compilation with Visual
10 Add non-standard SRU diagnostic: 235: "Database does not exist".
11 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
12 Update SRU to Bib-1 diagnostic maps accordingly.
14 CCL: add two new diagnostics for unsupported masking. The new
15 diagnostics are: "Embedded truncation not supported" and
16 "Single charcacter mask not supported".
20 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
24 Build YAZ for Ubuntu Oneiric.
26 CCL: allow parantheses for proximity operands. For example CCL query
27 (a) % (b) is now allowed.
29 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
30 marked dead, rather then being destroyed. If not, the session memory is
31 being free'd before the search/scan handler is finished. Also destroy
32 'request' memory in request_release rather than in various places,
33 which resulted in leaks from time to time.
37 cql_sortby_to_sortkeys: honor sort prefix.
39 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
40 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
41 The rpn2cql family of functions now always returns quoted CQL terms.
43 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
47 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
48 sequence is treated as one. For example, &&a=b&&&c& is identical to
53 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
54 APDUs for a connection to a WRBUF.
58 Fix cql_sortby_to_sortkeys. Completely broken before.
60 Make CCL's @truncation work again.
64 New ZOOM connection setting: tproxy. It's like proxy, but does not
65 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
66 to set resolved address + port for a connection outside ZOOM itself.
68 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
72 Fix uninitialized variable in Solr spell support (could cause SEGV
73 for SRU response decoding).
75 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
76 back-end's addinfo through into the ZOOM response addinfo.
78 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
79 they are separated by a colon and a space rather than simply
84 Add support for Solr spell-checking/suggestions through ZOOM.
85 If a Solr target has been configured correctly for spelling-checking
86 and suggestions, these will now be returned on the ResultSet option
87 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
91 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
92 with a flag whether to substitute escape sequences or not.
96 Fix nmem_strsplit_escape to substitute escape char properly.
98 New option for zoomsh -e , which makes it abort on first error and
99 return process exit code to indicate success/failure.
101 YAZ options utility supports special option -- which makes all it treat
102 all following arguments as non-options.
104 --- 4.2.15 2011/09/16
106 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
107 searched if absolute filename is given.
109 Fix conv_xslt() error-reporting when stylesheet is not found.
110 (The value of fullpath is meaningless in this situation.)
112 --- 4.2.14 2011/09/07
114 Fix problem in CQL sort node creation: un-initialized memory.
116 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
117 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
118 CQL sortby depending on whether Type-1 or CQL is actually sent to the
121 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
122 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
124 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
125 will make it possible to use both single-character mask (#) and wildcard (?)
126 in CCL . Throw diagnostic for left truncation because that is not supported
129 --- 4.2.13 2011/09/01
131 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
132 cases using escapes (\-sequences) and masking.
134 PQF parse fix: A trailing backslash followed by end-of-string (\0)
135 would result in a read one byte beyond string.
137 rpn2ccl may use Z39.50 masking for terms (t=z).
139 ICU check fix. Don't include library -lCrun on Solaris, unless present.
141 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
142 not --cppflags (which seeems like an error in icu-config).
144 --- 4.2.12 2011/08/27 RPM package only
146 cql2ccl: fix conversion of terms: operator characters were not
149 --- 4.2.11 2011/08/25 RPM package only
151 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
152 CCL parser will map both # and ? to their regular expression
153 quivalents (. and .*).
155 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
156 of reserved CQL characters.
158 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
159 is, so that they are passed through.
161 --- 4.2.10 2011/08/24
163 ZOOM SRU mode: more aggressive re-connect.
165 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
166 made available as a utility function, declared in <yaz/logrpn.h>
168 rpn2cql_structure() supports proximity nodes (except that the Type-1
169 proximity node's "exclusion" binary is ignored, as there is no way to
170 express that in CQL). Fixes bug #4564.
174 Fix SEGV that could occur if set command of zoomsh was given without
175 value (2nd argument).
177 Fix SEGV that could occur if unsupported transport was given for
178 COMSTACK - say https (when SSL was unavailable).
180 Build yaz-url on Windows too.
184 New utility to get web content. Header is url.h. A command line tool
185 yaz-url is part of the distribution and packages.
187 Fixes for SSL COMSTACK (when gnutls is in use).
189 New functions yaz_base64{encode,decode}. Header is base64.h.
193 ZOOM C includes HTTP response buffer as additional info if it fails
194 to decode the SRU response.
196 Make wrbuf_json_puts available.
200 zoom: throw diagnostic for invalid value for option "sru". Before a
201 bad SRU request was sent.
203 Adding new utility wrbuf_vp_puts.
205 Add cclxmlconfig.obj to win/makefile. It was missing completely.
209 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
210 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
211 redirect was used at the same time.
213 MARC line mode decoding: be less picky about length given - first
214 5 digits of header that is.
216 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
218 Changes to decoding of SRU records: a record with recordPacking=xml is
219 modified with a new root element <yaz_record> if the recordData contains
220 multiple children elements. This is to make the record XML parseable
223 RPN to SOLR conversion: encode special characters.
225 Generic Frontend Server: fix uinitialized member, stepSize.
229 Fix a bug in SRU decoding of records.. The database records stored
230 had un-initialized memory, but it would only be seen with yaz_record_render
231 and type_spec="ext" .
233 Fix a bug in ccl_qual_dup introduced in 4.2.3.
237 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
241 Add new utilities to convert from CQL to CCL . These utilities have
242 prefix cql_to_ccl defined in cql.h.
244 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
245 lead to memory heap corruptions when ICU utilities were in use.
249 Make compilation work without Libxml2.
251 yaz-client: remove redundant blanks in display of searchResult-1 term
256 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
257 resulting CQL node (tree) in a new node CQL_NODE_SORT.
259 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
260 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
261 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
262 Note that the CQL sortby spec is only converted when the GFS is already
263 converting from CQL to RPN (cql2rpn element).
265 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
266 specify whether to collapse delimitors or not. The existing nmem_strsplit
267 do collapse (collapse parameter = 1).
269 Windows installer: For NSIS, set InstallDir depending on x86/x64.
271 Rename internal func yaz_use_attribute_create. While non-static, this
272 function is not declared in a public header.
276 Add -lCrun when linking with ICU on Solaris.
278 More quicks character set conversions for OPAC records.
282 fix problem with record_render: records were converted (character set
283 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
287 SRU: add methods for handling DADS SRU-proxy facets.
289 Separate OPAC record character set for ZOOM_record. yaz_record_render
290 allows a character set given as charset=from/opacfrom,to where 'from' is
291 the character set of a bibliographic record, 'opacfrom' is character set
292 of OPAC record and 'to' is the target character set.
296 yaz-client: show may XML format records. Command show followed by 'format'
297 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
300 src/stemmer.c: Avoid using unnamed union. It is not supported by some
303 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
306 Update yaz.spec to operate on both SLES11 / Centos 5.5.
308 RPM: Release includes 'indexdata' name. Use indexdata in release name so
309 this package can be distinguished from other vendors.
311 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
312 as determined by configure
314 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
316 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
317 returns no error and no record, the present request is considered
318 partial (only a subset of the records could be returned by backend), and
319 so it is appropriate to set Present Status to partial-4.
323 Move yaz-config man pages to section 1.
325 More documentation about SOLR.
327 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
328 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
329 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
330 peers on some Linux systems. However, in general that does not work
331 so YAZ can not rely on that to work. Debian changed behavior in this
332 respect from Debian lenny to Debian squeeze (still testing as of Oct
334 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
336 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
340 Fix yaz-config output: echo_source not set correctly by configure.
344 SOLR WebService support for yaz-client and ZOOM.
346 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
348 --- 4.0.12 2010/08/17
350 Z39.50 facet support. Facet specifications are passed for search in
351 other-information with ASN.1 as defined in facet.asn and OID
352 .10.1000.81.5 . Facets are expressed as an Attribute list as known
353 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
354 3 is limit (number of entries to get in response). yaz-ztest returns
355 dummy facets if a client asks for them.
357 --- 4.0.11 2010/07/09
359 CCL fixes: bug 2895 and bug 3539.
361 GR1-display: add comma in display - was removed by mistake in
364 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
366 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
368 --- 4.0.10 2010/06/18
370 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
371 result set from a connection. The result set will be on its own
372 thereafter; no operations on it will perform retrievals from a target.
373 Only cached copies are returned.
375 ZOOM C:fix case for HTTP servers responding with Connection:close.
376 Ensure that if there is a current task it is resumed (like fetching
377 more records in a result set) . Bug #3484.
379 PQF parser: use odr_atoi for Odr_int (not atoi)
381 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
382 values that contain any non-digits are treated as string attributes
383 (previously decoding only checked for leading character ([0-9]). PQF
384 encoding: attribute string values are not surrounded by double-quotes.
388 New utility for managing threads - thread_create.h.
390 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
391 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
392 but YAZ' implementation do.
394 Fixes for yaz_cond-functions on Windows 7.
396 DLL export more symbols.
398 zoomsh: show record do NOT render opac.
400 Remove *.la files from Debian and RPM packages.
404 Debian package libyaz-dev depends on libgnutls-dev again (was
405 removed in YAZ 4.0.6, but due to Libtool it is still needed
406 even though yaz-config do not list libgnutls libs).
408 ZOOM: Use only one WRBUF for returning string results for
409 ZOOM_resultset. Reduces memory usage for ZOOM in general.
411 ZOOM: ZOOM_connection do not use a shared pointer to
412 ZOOM_resultset after ZOOM_resultset is destructed by
413 user. Reverts to YAZ 4.0.4 behavior.
417 record-conv: fix problem with at least one XSL conversion -
418 due to probably incorrect usage of XML XSL documents.
422 Fix yaz-config for static mode and the use of SSL (gnutls).
426 Forward decl timeval struct in mutex.h and gettimeofday.h.
428 yaz-config: fix 'static' mode linking.
432 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
433 are wrappers for pthreads or Windows. For Windows these are put in
434 a separate DLL: yaz_cond4.
436 libyaz.la (whole source) is compiled with thread. If thread support
437 is enabled enabled, all source of YAZ is compiled with treading support.
438 This allows core utilities such as yaz_log to use thread facilities.
439 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
440 thread utilities. This commit moves mutex utilities (mutex.c) from
441 libyaz_server.la to libyaz.la.
443 yaz-json-parse displays leading text until error.
447 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
448 patch from Giannis Kosmas.
450 SRU: no longer URL encode SRU database. The URL for an SRU server is
451 a URL and such is alreeady encoded - at least when given with leading
452 http:// or https://. This reverts behavior to YAZ 3.0.50.
454 Support for new MARC XML notation TurboMARC which like MARCXML is a
455 complete representation of MARC/ISO2709.. This one, however, is more
456 compact and allows for faster processing with XSLT. TurboMARC can be
457 used in the marcdisp.h API, from the yaz-marcdump utility and from
460 yaz-ztest can be configured - via the database - to perform certain
461 delays when it performs operations search, present and single record
462 fetch. This allows testers to make yaz-ztest act as a real or even slow
463 Z39.50 server. Refer to the yaz-ztest man pages for details.
467 wrbuf_destroy allows NULL WRBUF passed to it.
469 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
471 Add ZOOM_connection_close.
473 No fixed size buffers for ZOOM shell - bug #3257.
475 tstodr: make it work on s390 platform.
477 New icu iterator-functions. The new icu_iter-functions makes it possible
478 to use ICU chains from many threads.
480 yaz-client: better syntax check for show command.
484 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
487 New simple local-file XML include facility which allows file glob-patterns.
488 Refer to yaz/xml_include.h.
490 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
493 ZOOM_record_get supports new parameter "format" which makes it format XML
496 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
497 JSONText in ECMA-262) is JSONValue, not JSONObject.
501 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
502 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
504 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
505 POSIX/Unix builds .so with major version 4.
507 Remove old LOG_-defines from log.h. They have been obsolete and
508 undefined by default for the last 5 years.
510 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
512 GFS: Remove socket (int *fd) from search_rr handler. The socket
513 descriptor ptr is a facility that allowed a search handler to supply
514 a socket which would serve as a callback - when search was complete.
515 This facility has now been in use for years.
517 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
518 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
519 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
520 returns 'const char *' rather than 'char *. The returned string is
521 read-only and should not be modified by applications. COMSTACK cs_close is
522 now a void function - it no longer returns int. No applications check for
523 the value and the implementations has always returned 0.
525 ZOOM: use size_t for scan hit counts and str size. Functions
526 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
527 occ (hit count) and len (string length) are now of type size_t pointer
528 rather than int pointer. This is to be able to represent large hit counts
529 and to also just to use the proper type for string length (strlen result).
531 New JSON parser. Refer to include/yaz/json.h .
533 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
534 Used to be int in some cases. Many wrbuf_-functions used to return an int
535 indicating some length.. These return values were never used. And so they
538 ODR: odr_malloc, odr_total now takes size_t for size.
540 clone_z_type: fix leak; occurred for encoding failures.
542 --- 3.0.52 2009/12/03
544 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
545 bug was introduced in 3.0.51.
547 --- 3.0.51 2009/12/02
549 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
551 tcpip comstack: fix leak for getaddrinfo.
553 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
554 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
555 Decoding of SRU "path" database is performed by private function
556 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
557 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
559 yaz-client: honor base command for SRU. Change when database setting
560 is applied for SRU and ensure it is kept when a connection is reset.
561 Change also the way errors are displayed or SRU (decoding of packages).
563 --- 3.0.50 2009/11/02
565 Add support for extra request / response data for SRU codecs and GFS.
566 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
567 for extra data response buffer and length. For the GFS, both request
568 and response data (XML) is carried in extra_args and extra_response_data
569 for the search handler. Patch by Ko van der Sloot.
571 ZOOM: For queries that cannot be converted to the specified rpnCharset,
572 ZOOM now returns a diagnostic on the client-side ('invalid query' /
573 10010). This fixes bug #2113.
575 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
576 cmdfile included a 'quit' command that would result in a memory violation.
578 --- 3.0.49 2009/10/01
580 Make a number of functions defined in xmlquery.c static. These have
581 never been declared in a public header file (yaz/xmlquery.h) and was
582 made public by mistake.
584 Improve speed of character conversions (iconv utilities). This makes
585 conversions from MARC-8 faster.
587 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
588 unless type desired is "raw". This will prevent type "xml" from
589 returning ISO2709 .. Which obviously can not be XML parsed.
591 Fix memory leak in ZOOM that would occur if option apdulog was used
592 on a re-used connection.
594 Frontend server logs HTTP requests.
596 Frontend server now sends Z39.50 close when it times out (sesssion has
597 been idle for too long). Versions 2.0.30 and earlier also sent close.
598 But due to a mistake this was disabled in all versions after that, i.e.
599 the server would just close the socket immediately.
601 yaz-client emits a better message when receiving an unrecognised
602 userInformationField.
604 Skip zero-length subfields when decoding ISO2709. This rare case happens
605 if a record has two FS characters in a sequence. Without this patch
606 there would be a reference beyond char array in using_code_len fragments
609 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
611 --- 3.0.48 2009/08/28
613 The show command offered by the zoomsh command now takes a 3d optional
614 parameter type which is what is passed to ZOOM_record. If the type
615 argument is omitted, "render" is used.
617 RPN to CQL conv may use USE string attributes (bug #2978).
619 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
621 --- 3.0.47 2009/07/08
623 Function yaz_xml2query allows a diagnostic element in the PQF XML
624 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
625 code and additional info respectively.
627 The BER BOOLEAN is now the integral type Odr_bool which still happens
628 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
629 typedef'd to Odr_int. This is still an integral 'int', but it may be
630 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
631 ASN-1 compiler as well as programs has been updated to use the new types.
633 --- 3.0.46 2009/06/08
635 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
636 only the bibliographic record was rendered. For type=opac, an OPAC
637 record is only returned if it is present.
639 iconv: small fix for encoding of advancegreek.
641 yaz-client: avoid double display of SRU/SRW records (bug #2798).
643 yaz-client: option auto_reconnect=on really reconnects.
645 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
647 server: avoid null ptr ref for for yaz_poll errors.
649 build: fix RPM build for RHEL 5.3.
651 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
653 --- 3.0.45 2009/03/31
655 Fixed bug #2709: TCP connect returns Invalid argument.
657 Fixed compilation for mingw.
659 Honor charset for raw records (ZOOM_record_get).
661 Fixed use of errno for threaded mode that was seen on Solaris 10.
663 Fixed argument passing with blanks in value for Windows Service.
665 Disable YAZ' own log rotate by default (no 1 GB limit).
666 The variable l_max_size which specifies the log file limit is set to 0
667 (DISABLED): This is due to the fact that YAZ is most often deployed using
668 logrotate. Also YAZ can not perform log rotate because of unsufficient
669 permissions (setuid).
671 --- 3.0.44 2009/02/17
673 List supported encodings in man page for yaz-iconv.
675 Fixed missing SSL libs for --libs output
677 Re-established OID record syntax application-xml. Nobody should use it
678 but we don't want to change soname because of this symbol being absent.
680 --- 3.0.42 2009/02/02
682 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
684 Added member named_result_sets for init handler struct for the GFS. This
685 allows a server to disable named result sets.

707 Added new ICU test case which illustrates removal of diacritics.
709 --- 3.0.41 2008/12/29
711 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
713 --- 3.0.40 2008/12/29
715 For configure, using option --without-xml2 also disables Libxslt/Libexslt
718 Fixed bug #2352: yaz-marcdump crashes for certain record.
720 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
722 Added support for Danmarc2 to UTF-8 conversion.
724 Added support for ISO5426 to UTF-8 conversion.
726 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
727 implementation version.
729 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
731 --- 3.0.38 2008/11/10
733 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
734 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
736 ZOOM C now interprets databaseName option for ZOOM connection as path
739 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
741 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
743 Dummy Libxml2 types no longer defined in headers of YAZ'.
745 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
748 --- 3.0.36 2008/09/26
750 Various ODR chapter fixes.
752 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
754 Added missing source for Windows compilation, mutex.c.
756 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
758 For SRU connections in ZOOM all records up to "count" are now fetched.
760 Fixed crash in generic frontend server (and yaz-ztest) which occurred
761 in Windows due to bad error handling for Libxml2.
763 Added facility for sending arbitrary records (ASN.1 any) using
764 ZOOM C's Extended service update. Patch by Sam Reynolds.
766 New options for ZOOM C's connection, logapdu which makes ZOOM log
769 --- 3.0.34 2008/06/18
771 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
773 --- 3.0.32 2008/06/12
775 Fixed memory violation that could occur when decoding UTF-8. This bug
776 was only present in 3.0.30 of YAZ.
778 --- 3.0.30 2008/06/06
780 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
781 GNU TLS is used by default (if found).
783 yaz-ztest returns OPAC records if a client asks for OPAC.
785 Improved speed of MARC-8 encoding.
787 Added support for lossy and loss-less MARC-8 encoding.
789 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
791 Added new Windows Service wrapper (sc).
793 yaz-client's itemorder command may now send a file.
795 Fixed yaz-marcdump to allow the use of NS prefix for record element.
797 Added new function yaz_log_xml_errors.
799 Allow (but warn) unknown XML attributes in MARCXML parsing.
801 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
803 The UTF-8 to MARC-8 conversion now uses a different set of characters
804 for Greek symbols. Bug #2120.
806 --- 3.0.26 2008/02/21
808 Added yaz_daemon (daemon.h).
810 Fixed bug #2068: pkg-config trouble
812 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
814 --- 3.0.24 2008/01/28
816 Document --with-xml2 option.
818 Added OPAC XML XSD (etc/opacxml.xsd).
820 Allow glob mask for name attribute in retrieval element for the
821 generic frontend server's retrieval facility.
823 Changed yaz_poll_poll to return yaz_poll_except for all returned events
824 except POLLIN/POLLOUT.
826 Fixed error handling in cs_listen. Bug #2037.
828 --- 3.0.22 2008/01/20
830 Fixed version in yaz/yaz-version.h.
832 Fixed bug #2027: Crash when closing connection.
834 Changed configure so that ICU support is only enabled if only ICU
835 and Libxml2 is available (because the ICU chain is XML based).
837 --- 3.0.20 2008/01/15
839 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
840 is built. Only this DLL depends on the ICU runtime.
842 yaz-ziffy is no longer part of YAZ. It is distributed separately by
843 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
845 Changed license of CCL module to 'Revised BSD'. After consultation with
846 remaining members of the original EUROPAGATE consortium, we are re-issuing
847 the CCL module without a separate license. The software was developed by
848 Index Data as part of a research project. The special license was included
849 to help feed usage information back to the project consortium to support
850 project evaluation. At this time, the project consortium has long-since
851 disbanded, and the majority of the original principals have retired. At the
852 same time, we have significantly modified the software during the following
853 years, to the point where very practically no original code remains. To
854 simplify re-use of the software, we have contacted those members of the
855 consortium who could be reached, and agreed to re-issue the module as a
856 proper part of the YAZ package.
858 Tcl scripts uses /usr/bin/tclsh as preferred shell.
860 CQL closer to being version 1.2 compliant. CQL also allows free-form
861 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
864 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
865 bug could make Extended services handling crash in the ZOOM layer. This
866 bug was only present in YAZ 3.0.18.
868 --- 3.0.18 2007/12/19
870 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
873 yaz-marcdump reads and writes collection wrapped records.
875 Handle OPAC for record conversion module.
877 Fixes for ICU wrapper.
879 Allow ICU libs to be controlled with --with-icu .
881 --- 3.0.16 2007/11/12
883 Added yaz_poll which is a wrapper for select/poll. When poll is available
884 and non-buggy, it is used, by yaz_poll . This allows more than 1024
885 sockets to be in use.
887 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
888 functionality through an XML based configuration (ICU chain). This system
889 is useful for search facilities such as Pazpar2 and Zebra that needs to
890 perform tokenization of indexed material. The ICU code in a separate
891 library libyaz3_icu.a.
893 Added HTTP tunnel facility for COMSTACK, bug #1752.
894 This is a facility that allows a Web proxy, such as squid, to tunnel
895 Z39.50 traffic. This facility is "transparent" to must applications
896 using YAZ. It's enabled by using pseudo transport connect: followed by
897 the proxy address, followed by command, then follwed by he regular
898 "virtual" addresss. For example,
899 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
901 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
903 --- 3.0.14 2007/09/21
905 Fixed bad memory reference in ZOOM_record - cuased by member not being
906 initialized. This was a problem only in YAZ 3.0.12.
908 Fixed bug in conversion from MARC to XML: Non-XML characters in control
909 fields were not removed.
911 Changed the way C code is generated from codetables.xml. Made a MARC-8
912 conversion trie for each characterSet section rather than codeTable.
913 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
914 of codetables.xml from Larry Dixson, LOC. Bug #1464.
916 --- 3.0.12 2007/09/12
918 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
919 from ZOOM_record_error).
921 ZOOM C function ZOOM_record_get returns record schema for type="schema".
923 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
925 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
927 Better SRW-to-Bib-1 diagnostic mapping.
929 ZOOM C and yaz-client announces SRU version 1.2 by default.
931 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
934 Fixed in yaz_sru_decode to allow other version than 1.1.
936 --- 3.0.10 2007/08/22
938 Added support for SRU scan for ZOOM.
940 Added support for the use of the older versions or Extended Service
941 Update in ZOOM. To faciliate this, an option "updateVersion" may be
942 set to the version , 1=first, 2=second, 3=third. The third version is
943 what ZOOM C has used so far. And that, obviously, is the default.
945 Added support for CCL queries in Z39.50 queries sent to the GFS (and
946 therefore in Zebra and in SimpleServer-based applications). The new
947 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
948 qualifier file used to transform incoming CCL queries into Type-1 RPN,
949 which is passed into the back-end search callback function.
951 Added support for HTTP Basic authentication in clients: the SRU/W
952 codec encodes the username/password elements of the PDU structure
953 appropriately, and these may be set using the "user" and "password"
954 options in ZOOM-C applications (the same options that are used for
955 Z39.50 authentication).
959 Fixed bug #1208: SSL appears to be broken in ZOOM.
961 Fixed bug #1206: Libxml2 include path weirdness.
963 Added oid_name_to_dotstring.
965 Allow elementSetName to be specified for ZOOM C record update.
967 Allow waitAction to be specified for ZOOM C based for Extended Services.
969 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
970 syntax OID. Bug introduced in YAZ 3 series.
972 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
976 Fixed bug #1157: yaz-client does not read .yazclientrc from current
977 directory. yaz-client now reads commands from file given by option -f
978 if specified; then tries to read .yazclientrc in current directory.
979 Failing that, it reads .yazclientrc from user's home directory.
981 Added support for correlationInfo Note and ID for Record Update via
984 Added yaz-client command querycharset which specifies character set for
985 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
986 (termListAndStartPoint).
988 Charset ISO5428:1984 is an alias for ISO5428-1984.
990 Implemented a way to perform scan in a result set using Z39.50. This
991 is achieved by attaching the result set name in the characterInfo
992 (type InternationalString) of OtherInformation in the Scan Request PDU.
993 The result set is identified in the otherinformation by the new OID:
994 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
995 This allows for scan in result set and faceted search . Zebra did some
996 of this in the APT term using attribute type 8 and value being result
997 set. Using the OtherInformation approach for this is cleaner and easier
998 to work with in proxies and the like. This facility can be used in
999 yaz-client using new command setscan which takes a result set as first
1000 argument, start position (APT) as second.
1002 Changed decoding of SRU XML packed records to deal with servers that
1003 have recordData with XML data with multiple root nodes. Also make
1004 comparison for recordPacking case insensitive. Again, one server
1005 returns "XML" where others return "xml".
1007 For SRU responses allow Content-Type application/xml as well as text/xml.
1009 --- 3.0.4 2007/05/21
1011 Fixed bug in character set conversion of BER strings. Bug introduced
1014 --- 3.0.2 2007/05/08
1016 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1018 For OID class, use oid_class consistently.
1020 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1023 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1024 character set for bibliographic information interchange". By Giannis Kosmas.
1026 Added documentation on new OID API.
1028 --- 3.0.0 2007/05/02
1030 Changes to generic frontend server interface: added new member
1031 'query_charset' for bend_initrequest structure. A backend init handler
1032 should set this member to its native character set for query terms.
1033 When defined, the frontend server logic will announce this character set
1034 to a client if the negotiationModel bit is set by the client. All server
1035 implementors are encouraged to specify this. If a backend server does not
1036 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1038 Added CCL utility to remove terms (stop words) from resulting RPN
1039 tree. This is handled by functions with prefix ccl_stop_words_ .
1041 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1042 terms in RPN queries.
1044 Clean-up the CCL API. Moved some internal structures from ccl.h to
1045 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1046 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1047 This is replaced by ccl_parser_find_str which takes a string instead.
1049 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1050 libyaz.la is the core of YAZ except the generic frontend server and
1051 does not depend on POSIX threads anymore. libyaz_server.la is the
1052 generic frontend server facilities and uses POSIX thread functionality
1053 if available. The libyaz.la no longer depends on POSIX threads because
1054 the number of global structures is limited. NMEM no longer re-uses blocks
1055 between threads ; it simply free's memory immediately but allocates in
1056 "large" chunks as usual. We don't expect any performance penalties
1057 because of this. The yaz_log system is still using a global log_level so
1058 caution must be taken when modifying it with yaz_log_init_.. +
1059 yaz_log_mask_str. This, however, should not cause any trouble because
1060 these functions are called during initialization of application code
1061 anyway. `yaz-config --libs server` returns libs for server applications;
1062 `yaz-config --libs` returns libs for non-server applications.
1064 New OID database - with public definitions in oid_db.h. Removed old OID
1065 database including the head oid.h and definitions such as enum oid_value
1066 and struct oident. The new OID database uses the same string names as
1067 before but the 'protocol' is gone. There are now only two representations
1068 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1069 converts from string to OID; functions with prefix yaz_oid_to_string
1070 converts the other way.
1072 Change to emit_term() in CQL-to-PQF query translation: when a term has
1073 the /regexp relation modifier, do not process it for leading and
1074 trailing "^" and "*", which have quite different meanings in regular
1077 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1078 write handlers no longer carries a 'last' parameter. This will make
1079 yaz_iconv flush "less" characters. A flush is performed by call to
1080 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1082 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1083 removed, because function yaz_query_to_wrbuf does the same.
1085 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1086 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1088 Deprecated MARC utility functions removed.
1090 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1093 Branch split: YAZ_2_1_55_branch
1095 --- 2.1.54 2007/03/16
1097 Fix to ZOOM-C so that transparent reconnection is properly handled on
1098 connections that are in asynchronous mode.
1100 Fixed compilation on OpenBSD 4.0.
1102 Large strings in GRS-1 records are now properly displayed in yaz-client.
1104 Added character conversion support for "advancegreek"; based on patch from
1107 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1108 sequence is met. Before the error was not set so it would be unknown.
1110 Adjust yaz-marcdump MARC reader so that it skips until record separator
1113 --- 2.1.52 2007/03/07
1115 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1116 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1117 fd_set structure used as a bitmask for the FDs to be selected on.
1119 Using ACX_PTHREAD macro to check for POSIX threads.
1121 Fixed have-vsnprintf check.
1123 --- 2.1.50 2007/02/23
1125 Fixes for configure on BSD. Bug #900.
1127 Added snprintf/vsnprintf wrappers for systems that don't have
1128 limits (heavens forbid).
1130 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1131 created before all previous tasks were completed and removed from the
1132 task queue, the new task could be removed by a mistake.
1134 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1136 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1138 Fixed bug #832: Problem with MARC/charset in yaz-client.
1140 Fixed bug #668: save command line history for yaz-client.
1142 Fixed bug #830: pkg-config support.
1144 --- 2.1.48 2007/01/23
1146 Extended ZOOM result set options with two options that may be read by
1147 a client: resultSetStatus and presentStatus with values as specified for
1149 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1151 Fixed bug #827: Using SSL fails on Debian etch.
1153 Fixed bug #826: Weird looking chars for set of MARC records.
1155 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1156 that is treated as an ItemOrder with itemRequest being an XML document
1157 external. The value of "doc" is the content.
1159 Extended the GFS search facility. New member of bend_search_rr
1160 'estimated_hit_count' signals that hits is known to be an estmate
1161 (higher or lower than real hit count). New member 'partial_resultset'
1162 signals that the search was partial (hit count is lower or equal than
1163 real hit count). For Z39.50, the information is stored in resultSetStatus
1164 member of SearchResponse APDU. For SRU, the information is signalled
1165 via SRU diagnostic 59: "Result set created with valid partial results
1168 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1170 --- 2.1.46 2007/01/13
1172 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1174 Added ZOOM_connection_peek_event.
1176 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1177 the following new functions:
1178 ZOOM_event_nonblock, ZOOM_connection_process,
1179 ZOOM_connection_get_{socket,mask,timeout},
1180 ZOOM_connection_fire_event_{timeout,socket}.
1181 The existing blocking event handler, ZOOM_event, is a wrapper for the
1182 + blocking ZOOM_event_sys_{poll,select}.
1184 Implemented function ccl_xml_config which parses XML version of CCL
1185 configuration (bug #798).
1187 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1189 Added timings utility (yaz/timing.h)
1191 --- 2.1.44 2007/01/03
1193 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1196 Fixed bug #779: Rotation of apdu.log fails.
1198 Fixed for character set conversions:
1199 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1200 Honor G1 set in MARC-8 decoding.
1202 --- 2.1.42 2006/12/17
1204 Fixed bug #775: char conversion does not handle Alternative UTF-8
1207 Implemented function yaz_marc_read_line which parses MARC line format
1208 records. There is a wealth of formats out there. So far, this function
1209 reads line records produced by yaz_marc_write_line.
1211 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1212 more generic and easier to remember(!) options: -i format and -o format
1213 which specifies input format and output format respectively - where
1214 format is one of "marc", "marcxml", "line", "marcxchange".
1216 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1217 does not print anything except warnings for records.
1219 For yaz-marcdump, added support for MARC split into files (-s) with a given
1222 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1223 spec, at http://www.loc.gov/standards/sru/record-update/
1224 This has changed the binary layout of the following structs:
1225 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1226 bend_update_rr . Patch by Ko van der Sloot.
1228 Added GFS utility function bend_assoc_is_alive which returns 1 if
1229 association is still alive (client is connected); 0 otherwise (client
1230 closed connection). This allows busy servers to stop working for
1233 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1234 been a separate piece of software. This version of ziffy has been modified
1235 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1237 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1239 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1240 Client code may now interrogate options such as "init_opt_sort" to
1241 find out whether the server claims to support various options.
1243 --- 2.1.40 2006/11/27
1245 Added utilities yaz_{set,get}_esn to set/get element set name from
1248 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1249 of YAZ and has been so since YAZ 2.1.10.
1251 Implemented ZOOM_record_error which returns error information for
1252 record (surrogate diagnostic).
1254 --- 2.1.38 2006/10/31
1256 Updates for SRU Update by Ko van der Sloot:
1257 1. Changed name from "operation" to "action"
1258 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1259 versions in the code, marked as 'backward compatible'.
1260 3. Added diagnostics for SRU Update.
1262 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1264 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1266 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1268 For GFS, fixed problem with SRU diagnostic 'First record position out of
1269 range' being issued for 0 hits.
1271 zoomtst10 part of Windows Build.
1273 --- 2.1.36 2006/10/13
1275 Implemented yaz_filepath_comp which splits a path into file path
1276 components (required by Zebra 2.0.3+).
1278 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1279 BSD inspired license until now so this should not have any real impact on
1280 anybody. See http://www.opensource.org/licenses/bsd-license.php
1282 Fixed bug #687: Missing log lines.
1284 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1287 Fixed bug #689: SRU diagnostics to be added.
1289 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1290 whether a connection is idle (no more work do do).
1292 --- 2.1.34 2006/10/04
1294 Change type of optval from long to int for invocation of setsockopt with
1295 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1297 Added support for specifying the max log file size for the Generic
1298 Frontend Server. The size is given with option -r.
1300 --- 2.1.32 2006/09/21
1302 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1304 --- 2.1.30 2006/09/17
1306 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1309 Fixed bug in Generic Frontend Server that could cause a server to stop
1310 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1312 For the generic frontend server, the maximum record size is used as maximum
1313 size of incoming packages (SRU + Z39.50). The value until was previously
1314 only used in Z39.50 Init negotiation and, later, in a session controlled
1315 sizes of records returned. This is controlled using -k option. It can be
1316 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1318 --- 2.1.28 2006/09/04
1320 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1323 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1325 New option for yaz-marcdump -lpos=value which allows setting a portion
1326 of MARC header to a certain value.
1328 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1330 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1331 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1333 --- 2.1.26 2006/08/15
1335 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1338 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1340 --- 2.1.24 2006/08/08
1342 Fixed MARC ISO2709 encoding routines to deal with character set
1345 Minor changes to GFS logging. Database included in search request log
1348 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1349 cached/multiple records.
1351 Shared libraries are built by default on Unix+configure.
1353 Changed cql2pqf transformation to use a different evaluation order. The
1354 new order is: always, relation, structure, position, truncation, index
1355 and relationModifier. Old order was: always, relation, relationModifier,
1356 structure, index, position, truncation. Note that the the latter ones
1357 override former ones for identical attributes.. The new scheme means that
1358 it is possible to override any existing attribute with a relationModifier.
1359 And also that it is possible to override everything for the index rule
1360 (except the ones listed in relationModifier). No order is perfect but this
1361 one, we believe, covers more real cases.. The "always" should have been
1362 called "default", since the attributes there can be overridden with all
1365 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1366 compilation phase, but also for yaz-config --cflags output. This allows
1367 us to have public headers with Libxml2 stuff in them . It should also,
1368 eventually, make Libxml2 checks redundant in packages using YAZ, such
1371 --- 2.1.22 2006/06/15
1373 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1374 stored in uri, message and details.. Previously diagnostics were stored
1375 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1376 compatibility.. but he's probably the only one affected, so.
1378 Added support for CCL, compiled on the client side, in ZOOM-C. This
1379 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1380 input; the resulting query objects can be used for for searching with
1381 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1383 YAZ' configure searches for OpenSSL by default.
1385 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1386 SL_CTX_use_certificate_file. See
1387 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1388 for more info. Thanks to Ko van der Sloot.
1390 --- 2.1.20 2006/06/02
1392 Bug #600: SRU GET, POST support for yaz-client. Introduced
1393 command 'sru' which selects method SOAP/GET/POST.
1395 Allow missingValueAction to be specified for the sortspec string -
1396 function yaz_sort_spec. By default, the missing value action is null.
1397 Use ! to specify "abort". Use = followed by stringvalue to specify default
1400 Ensured that Present-handler (if defined) is called in GFS before any call to
1401 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1402 searchRetrieve requests.
1404 Documentation for YAZ is now based on the Docbook XML/XSLT using
1405 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1406 is no longer depending on jade/openjade or docbook-to-man scripts.
1407 PDF is no longer part of the distribution - but can optionally be
1408 made using DSSSL/jadetex or FOP.
1410 Added retrieval handling support in Generic Frontend Server to support
1411 conversion between MARC/XML as well as XSLTtransforms. See
1412 etc/yazgfs.xml for an example.
1414 Added Authentication support to Generic Frontend Server in SRU
1415 mode. Authentication using HTTP Basic is supported, as is the use
1416 of 'x-username' and 'x-password' parameters in the request itself.
1418 Added support for a new character set MARC8s identical to MARC8 except
1419 that it converts combined characters to single Unicode characters in the
1420 Latin-1 range (when possible).
1422 --- 2.1.18 2006/04/24
1424 ASN.1 compiler 0.4: generates brief Doxygen file header for
1425 generated .h/.c files.
1427 Utility yaz_iconv now supports conversion to MARC-8.
1429 New facilities for the MARC module. The reading - and writing of
1430 content are separate methods for the yaz_marc_t handle. The following
1431 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1432 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1433 format). Write functions have prefix yaz_marc_write_.. The existing
1434 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1435 available. Removed support for OAI-MARC and simplexml (not the
1436 simplexml from PHP5).
1438 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1439 to be returned for this connection.
1441 --- 2.1.16 2006/03/31
1443 Allow multiple languages and charsets to be specified with
1444 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1445 negcharset iso-8859-1,utf-8
1447 Translation of proximity nodes from CQL into PQF now works.
1449 Moved to automake 1.8, 1.9.
1451 Added function yaz_log_set_handler which allows a log handler to be
1452 installed. This handler will be called for all log messages. Output
1453 to file is also produced; but that can be disabled by passing NULL
1454 fname to yaz_log_init_file.
1456 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1458 For SRW (including GFS), accept application/soap+xml as content-type
1461 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1462 produces NO stylesheet reference even if a default stylesheet is specified
1465 --- 2.1.14 2006/03/14
1467 Updated Windows package to include yazd.dll + yazd.lib for the
1468 Development component.
1470 If the environment variable YAZ_LOG is set, then it is used as a
1471 string indicating the default level of logging to use if not
1472 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1473 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1474 used as before. So, for example, to omit warnings from YAZ logging,
1475 export YAZ_LOG=-warn
1477 cql_transform() now map structure and other attributes before indexes,
1478 so that index-specific structures and other attributes can override
1479 defaults. So now a combination of mapping specifications such as:
1481 index.dc.date = 1=date-modified 4=5
1482 does the right thing.
1484 cql_transform() now also respects the "always" mapping specification,
1485 which establishes an initial set of attributes to be used for all
1486 terms except where overridden by more specific attributes associated
1487 with the index, relation or modifier.
1489 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1490 which mode to use; one of "post", "get" or "soap" (SRW, default).
1492 Fixes for yaz_iconv routines: changed trie-based character set conversions
1493 to use only non-negative values for bit fields due to Sun's C compiler not
1494 supporting negative values.
1496 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1497 sequences where not read correctly. Fix by Rustam Usmanov.
1499 Updated win/makefile to use options, settings which makes things
1500 compile with VS C 2005.
1502 --- 2.1.12 2006/02/01
1504 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1506 In ZOOM socket code, use select instead of poll on MacOSX.
1508 ZOOM-C now support client-side compilation of CQL into RPN that is
1509 sent to the server, enabling CQL to be used against all Z39.50
1510 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1511 ZOOM_query object, and submit it using ZOOM_connection_search().
1512 The CQL-to-RPN translation uses a configuration file, the name of
1513 which must be specified in the Connection's "cqlfile" option.
1515 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1516 function, which takes as its start-term parameter a ZOOM_query object
1517 (which may have had either CQL or RPN set into it).
1520 --- 2.1.10 2005/11/29
1522 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1523 GFS to support this as well. Backend handler, bend_srw_update, does the
1524 update work. Code contributed by Ko van der Sloot.
1526 Allow retrieval of Search Result-1 information in ZOOM by the use of
1527 options that are attached to a result set. ZOOM documentation updated
1530 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1531 UTF-8 conversion. Patch by Raj Patel.
1533 Added option -m to GFS to control formatting of timestamps in log file.
1535 Added 'exit' as synonym for 'quit' in yaz-client
1537 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1538 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1539 for the new members. Patch by Ko van der Sloot.
1541 Added support for SRU POST. It is supported for content-type
1542 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1544 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1545 Instead make the library libyaz.la multi-threaded. Threading as a whole
1546 can still be disabled by configure option --disable-threads. Previosly,
1547 with older GLIBCs there were problems with MT libs under Apache. This
1548 has now been fixed a long time ago.
1550 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1553 CQL module modified to be case insensitive for relations/indexes/operations.
1555 Fixed bug in CQL transform code: incorrect value relationModifieder
1558 Added 'show all' command for yaz-client which retrieves all results
1561 Added new yaz-client, xmles, which takes a (private) OID and
1562 a document to be sent as an extended service request.
1564 Describe new yaz-client commands wait_response and set_auto_wait.
1566 Increase TCP/IP listener backlog from 3 (which I am guessing was
1567 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1568 that the socket will queue as many incoming connections as it's able
1569 to handle ongoing connections. In other words, it will never now
1570 refuse a connection that it would be able to handle merely because
1571 it's not got around to accepting() enough of the pending connections
1572 yet. This is the behaviour anyway under Linux, where the listen()
1573 argument is ignored; but not under BSD and on systems such as
1574 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1575 YAZ-based servers should now be uniform across operating systems in
1578 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1579 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1580 This allows yaz-marcdump to read large MARC batches (>2 GB).
1582 Modified all YAZ source files - except the source which is auto-generated
1583 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1586 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1587 corresponding to the existing *_setl() function. These allow option
1588 values containing arbitrary valuues.
1590 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1591 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1592 except that it returns an indicator of whether or not the sort
1593 criterion was accepted (0 for OK, -1 for invalid).
1595 --- 2.1.8 2005/06/07
1597 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1598 MARC output rather than returning "new" buffer.
1600 yaz-client warns about unknown init options.
1602 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1604 --- 2.1.6 2005/05/24
1606 Added support for SRW sort in Generic Frontend Server. Patch
1607 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1608 sortKeys - or NULL if none is provided.
1610 Fixed bug #307: It was impossible to specify indefinite/no timeout
1611 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1614 Added support for multiple languages and charsets to be specified in
1615 ZOOM. Each charset/language is separated by a blank. If negotiation is
1616 in effect in init-response, Option
1617 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1618 Code based on patch by Vasiliy Osadchuk.
1620 Fixed bug #306: infinite recursion that occurred when calling
1621 yaz_log_level_init as the first call (before other log level or
1624 Fixed bug in scan handling in front end server: if preferred-Position-In-
1625 Response was non-present, a NULL pointer referece was performed.
1627 --- 2.1.4 2005/04/26
1629 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1630 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1631 now defined for all those error codes. So instead of putting 109 in
1632 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1633 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1635 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1638 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1640 Program yaz-client now exits and produces an error message if multiple
1641 Z39.50 servers are specified on the command line (none or one allowed
1644 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1647 --- 2.1.2 2005/03/16
1649 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1651 Fixed bug #272: Preserve spacing for CCL terms.
1653 --- 2.1.0 2005/03/14
1655 Added support for virtual hosts and multiple backend servers for
1656 the YAZ frontend server. The configution is XML based and
1657 support specificition of CQL to RPN mappings and explain information.
1658 See section "Virtual Hosts" in the YAZ manual.
1660 Extended OPAC display utility. OPAC display utility renders
1661 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1662 to supplement yaz_marc_decode_wrbuf.
1664 Fixed a bug in MARC decoder that could caused it to crash for some
1665 invalid MARC records. More diagnostics and warnings where added in
1666 XML output (warnings, etc are stored in comments).
1668 --- 2.0.34 2005/02/08
1670 Fixes for UNIX domain sockets. Bug #261.
1672 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1674 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1675 Added yaz_marc_subfield_str which defines subfield lead string which is
1676 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1677 yaz_marc_endline_str which defines end of fields string used in
1678 YAZ_MARC_LINE format. Default string is newline.
1680 Experimental support for MarcXChange. This format can be produced
1681 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1682 http://www.bs.dk/standards/MarcXchange.xsd
1684 Added yaz-client commands scansize that sets maximum number of
1685 entries to be returned by scan.
1687 --- 2.0.32 2005/01/11
1689 Added support for SRW scan in yaz-client and Generic Frontend Server.
1691 * Added whereInList member to SRW Scan Term.
1693 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1695 Fixed NMEM system to return aligned blocks on the smallest boundaries
1696 that are suitably aligned for all possible types on the particular
1697 architecture YAZ is being built for.
1699 --- 2.0.30 2005/01/04
1701 Fixed numerious warnings that was issued with newer versions of GCC.
1703 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1704 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1707 Make YAZ Generic Frontend Server slightly faster.
1709 Enhance (and reduce) logging for Generic Frontend Server.
1711 Revert YAZ log system so that it flushes every write operation
1712 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1714 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1715 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1716 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1717 will effectively disable old definitions.
1719 --- 2.0.28 2004/11/09
1721 Added yaz_log_time_format which specifies log format using
1724 Added yaz_log_module_level which returns mask for a module. Value
1725 is non-zero mask a if module is enabled; zero if disabled.
1727 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1728 in include/yaz/cql.h.
1730 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1732 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1734 Fixed bug #172: RPM builds does not enable SSL.
1736 Doxyfile.in part of dist. Doxyfile generated by configure.
1738 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1739 are given and the corresponding component does not exist.
1741 Extend CCL documentation in YAZ reference. Describe r=r.
1743 --- 2.0.26 2004/10/01
1745 Fixed MARC->MARCXML conversion to properly deal with
1746 fields, subfields, indicators having non-ASCII characters.
1748 Fixed MARC->MARCXML conversion so that ASCII control characters
1749 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1752 Added YAZ GFS support for conversion from Z39.50 surrogate
1753 diagnostics to SRW surrogate diagnostics.
1755 Bug fix: YAZ GFS did not return schema in explainResponse.
1757 --- 2.0.25 2004/09/30
1759 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1760 now converts recordSchema to elementSetName as well as schema URI.
1762 Fixed bug in COMSTACK that prevented HTTP request packages from being
1765 --- 2.0.24 2004/09/29
1767 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1768 does not require white-space before and after the dash in a range, e.g.
1769 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1772 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1773 due to new GCC removing "redundant" code.
1775 Added yaz-client commands scanpos and scanstep that sets preferred
1776 position and step-size for scan.
1778 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1780 Added CCL utility ccl_qual_buf which parses one or more CCL
1781 spec lines in a buffer.
1783 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1784 of name and value - ignoring empty lines and comments.
1786 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1788 Added odr_get_element_path which returns current element path for an
1789 ODR handle. This utility is useful in error handling or user-defined
1792 Added ODR_PRINT utility odr_set_stream which is is a more generic
1793 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1794 to a write function and pointer to close function. The close function - if
1795 non-NULL - will be called during odr_destroy.
1797 Fixed bug in CCL parser where truncation char was not removed from
1798 right side when truncation=both was in effect.
1800 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1803 --- 2.0.23 2004/08/11
1805 Fix buffer overrun in CQL parser when dealing with proximity (%).
1807 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1808 to UTF-8/UCS conversion is now only based on codetables.xml.
1810 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1812 --- 2.0.22 2004/08/06
1814 Add support for more "commit changes" in ZOOM (uses Extended Services).
1816 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1819 Yet another small fix for configure of SSL.
1821 --- 2.0.21 2004/05/14
1823 Fix SSL libs for configure when --with-openssl=DIR is given.
1825 --- 2.0.20 2004/05/10
1827 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1829 SSL comstack now uses yaz.pem certificate file on server side
1830 by default. Certificate filename can be configured by calling
1831 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1833 Fix bug regarding multiple calls to ZOOM_connection_connect.
1835 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1837 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1838 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1840 ZOOM now allows inspection of X509 peer certificate for verification.
1841 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1843 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1844 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1845 as "modular" but it simplifies things.
1847 Added cs_get_peer_certificate to that returns peer X509 PEM.
1849 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1850 NULL if SSL is unavailable.
1852 Documentation about MARC decoding tools.
1854 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1856 --- 2.0.19 2004/03/30
1858 Rename CHANGELOG to NEWS to follow GNU style packing.
1860 Fix bug with missing initialization of member in init_diagnostics.
1861 This bug affects threaded version of GFS server.
1863 --- 2.0.18 2004/03/20
1865 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1868 Ensure zlib.dll is packed with Windows install.
1870 --- 2.0.17 2004/03/17
1872 Fix encoding of xsd:string to use text instead of CDATA.
1874 Fix endless loop in CQL parser with unbalanced ".
1876 Use a more compact way to store MARC-8 conversion tables.
1878 --- 2.0.16 2004/03/16 Debian only
1880 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1883 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1888 --- 2.0.15 2004/03/01
1890 Another fix for decoding of XML packed records.
1892 --- 2.0.14 2004/02/25
1894 Fixes for Chunked encoding. White space not ignored after length spec.
1896 Update NS and use default NS for SRW diagnostic elements.
1898 --- 2.0.13 2004/02/23
1900 Implement ZOOM_resultset_cache_reset which resets record cache.
1902 Implement ZOOM_resultset_sort which sorts a result set.
1904 Implement chunked HTTP transfer.
1906 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1908 --- 2.0.12 2004/02/16
1910 Added member 'schema' to bend_explain_rr structure so that backend
1911 can specify explain record identifier. Defaults to Zeerex 2.0.
1913 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1915 --- 2.0.11 2004/02/16
1917 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1920 Added init command for yaz-client which sends "extra" init request.
1922 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1923 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1925 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1927 Make ZOOM error code for "invalid query".
1929 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1931 --- 2.0.10 2004/02/05
1933 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1936 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1938 Added option -p <file> to make Generic Frontend Server to write PID file.
1940 Added option -D to put Generic Frontend Server in background on its own.
1942 Make ZOOM C recognize option "password". If unset, "pass" is used
1943 (for backwards compatibility).
1945 Fixed a bug in Generic Frontend Server that could make it crash if a
1946 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1949 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1950 Must be issued before open, in order to be in effect.
1952 --- 2.0.9-6 2004/01/12 Debian/Windows
1954 Make the SRU server more picky WRT unknown params, etc.
1956 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1958 New YAZ client command, options, that sets Z39.50 options.
1960 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1961 options from a string of tokens (one token for each option bit).
1963 Update SRW diagnostic code messages.
1965 --- 2.0.9-5 2004/01/07 Debian/Windows
1967 Handle user defined stylesheet for SRW/SRU.
1969 --- 2.0.9-4 2004/01/06 Debian/Windows
1971 Fix bug in decoding of Content-Length.
1973 --- 2.0.9-3 2004/01/06 Debian/Windows
1975 Fix a bug with decoding of XML packed records.
1977 --- 2.0.9-2 2004/01/05 Debian only
1979 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1981 Fix bug in SRW/SRU diagnostics decoding.
1983 --- 2.0.9 2004/01/05
1985 Fixed bug in Generic Frontend Server which could drop records exceeding
1986 preferred message size. Reported and fixed by Irina Dijour.
1988 Fixed calculation of package size for structured records in Generic
1989 Frontend Server. Reported and fixed by Irina Dijour.
1991 Fixed namespace for SRW/SRU diagnostics.
1993 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1995 --- 2.0.8 2003/12/22
1997 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1998 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2001 CQL changes to reflect recent changes to the specification:
2002 * Documentation talks about context sets instead of index sets.
2003 * Documentation talks about indexes instead of qualifiers.
2004 * The CQL-to-PQF transformer's configuration file now uses
2005 "index.set.name = <attributes>" instead of the old form
2006 "qualifier.set.name = <attributes>". (Both forms are still
2007 understood but the latter is deprecated.)
2008 * CQL terms with no explicit index specified are now interpreted as
2009 cql.serverChoice instead of srw.serverChoice (which of course
2010 behaves exactly the same.)
2012 --- 2.0.7 2003/12/16
2014 MARC conversion can now generate ISO2709 output in another
2015 character set. yaz-marcdump uses this facility if you invoke it
2018 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2019 functions from there can be used from C++.
2021 --- 2.0.6 2003/12/04
2023 Frontend server now transfers memory from decoded packages to stream
2026 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2027 references to show up.
2029 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2030 the ZOOM Abstract API. The older names for the same options are still
2031 also supported for the benefit of old applications.
2033 ZOOM-C supports "implementationId" and "implementationVersion" options
2034 to go along with "implementationName". These allow the user code to
2035 specify identification strings to be sent to servers.
2036 Add OID for the new ExtLite attribute set.
2038 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2039 as requested/supplid by Ere Maijala <ere@atp.fi>
2041 For generic frontend server, reverse the order of
2042 "toolkit-supplied / application-supplied" strings sent as implementationId,
2043 Name and Version. Also, remove the spaces around the slash. This brings
2044 the GFS in line with the behaviour of ZOOM-C on the client side.
2046 Add function ZOOM_scanset_display_term.
2048 yaz-client shows scan displayTerm if present.
2050 Utility yaz-iconv is now installed by default along with the man page
2053 Extend configure check for OpenSSL to use pkg-config where available (such
2056 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2057 server to specify uid/gid/mask for socket using the format
2058 unix:[user=uid,][group=gid,][umask=mask,]file=path
2059 If file= is omitted the existing format is assumed, e.g.
2061 in which case the mask is 0666 (rw for everybody).
2063 Major restructure of YAZ source. All source in libyaz is in src directory.
2064 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2065 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2067 Added man page for utility yaz-marcdump (used to be called marcdump).
2068 yaz-marcdump is installed by 'make install'.
2070 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2071 of incoming package failed.
2073 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2075 Change prototype of odr_perror: add const to message string.
2077 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2079 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2080 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2081 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2082 DNS lookup. There should not be any compatibility problems with this
2083 assuming that blocking=1 or 0 is used.
2085 Fix bad reference in UNIX comstack in function cs_addrstr.
2087 Fix for compilation on AIX.
2089 The generic front-end server (server/seshigh.c) now supports returning
2090 Init diagnostics to the client in User-information-field, in
2091 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2094 --- 2.0.4 2003/09/04
2096 Allow any CQL relation (not just all,any,exact,scr).
2098 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2099 that features the same UI.
2101 Implemented command update0 in YAZ client which is equivalent to
2102 update but uses old of Ext Update ASN.1.
2104 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2105 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2106 Previously no OID was used for this info.
2108 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2109 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2110 returns 'malformed search term' otherwise.
2112 SortResponse member resultCount now set to NULL in sort handler of
2115 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2118 Add three new utility functions for translating OIDs between various
2119 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2120 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2121 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2122 char *oid_to_dotstring(const int *oid, char *oidbuf);
2123 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2125 Reverted modifications for ES Update definition for z_IU0Update
2126 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2127 is back to YAZ 2.0.2.
2129 String value attributes for CCL parser.
2131 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2132 which their FirstSearch server returns in Init responses, sometimes
2133 carrying useful diagnostic information when Init fails. This has the
2134 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2135 "z39.50/oclcui.asn", where its definition is somewhat different from
2136 what OCLC document on their web-site, as required to interoperate with
2139 Support for anonymous authentication in yaz-client. Use the command
2142 * Fix the OID of the Index Data-local "admin" Extended Service from
2143 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2144 the 1000, which indicates a locally-defined OID, was a mistake.
2146 --- 2.0.3 2003/06/20
2148 Fix CCL directive @case handling so that it affects string match for
2149 both CCL keywords and qualifiers.
2151 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2152 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2153 Decoder has been updated with ASN.1 changes as listed in
2154 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2155 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2156 z_IUUpdate, remains unchanged.
2158 ZOOM_record_get may now return a record in a specific character set.
2159 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2160 "from" is the character set of record as returned by target. "to" is
2161 the character set to be returned. If omitted, "to" is UTF-8.
2163 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2165 New ODR utility, odr_getelement, which returns name of element for
2166 which encoding/decoding failed.
2168 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2169 in cases where a required element was omitted.
2171 Bug fix: some MARC8 sequences were not converted.
2173 New ZOOM option "step" which specifies number of records to be
2174 retrieved in one chunk. Used in conjunction with "start" and "count".
2176 SRW support for yaz-client. Use scheme http: to use it, e.g.
2179 yaz-client no longer does (un)intelligent character set conversions
2180 by default. Can be enabled with charset and marc_charset commands.
2182 xmalloc trace fix for 64-bit systems such as DEC alpha.
2184 Solaris 2.6 compile fix.
2186 New function, cql_strerror() translates SRW error codes, as returned
2187 by cql_transform_error(), into human-readable English strings. Used
2188 in yaz-client diagnostics when appropriate.
2190 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2191 converts it into a type-1 query which is sent to the server. This
2192 makes CQL available for use with all Z-servers, as opposed to the tiny
2193 minority that can handle CQL queries themselves.
2195 --- 2.0.2 2003/04/28
2197 New Debian package layout similar to the Redhat Package layout.
2199 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2200 and search result respectively.
2202 --- 2.0.1 2003/04/25
2204 Redhat package is now several packages: libyaz (runtime libraries),
2205 libyaz-devel (development and documentation, and yaz (utility programs).
2206 Package spec file by Morten Bogeskov.
2208 New member 'schema' in struct bend_fetch_rr which the name of requested
2209 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2210 handler MAY set this to reflect the schema of the returned record.
2212 New member 'display_term' in struct scan_entry. GFS now sets member entries
2213 and allocates scan entries to be filled by user scan handler. In previous
2214 version, entries member was allocated by the scan handler. That still works,
2215 but the GFS will ignore member display_term - assuming it was NOT set by
2216 the handler. The fact that the GFS now allocates the entries both allows
2217 for new members and makes a scan handler easier to write.
2219 Fix CQL lex buffer overflow.
2221 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2222 SRU default recordPacking is string.
2224 SRU protocol support for frontend server.
2226 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2228 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2230 Added scan for the ZOOM shell (zoomsh).
2234 * String Identifers for Schemas (Amendment 5).
2235 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2236 Old definition for schema
2237 Odr_oid *schema; /* OPT */
2242 Z_InternationalString *uri;
2243 #define Z_Schema_oid 1
2244 #define Z_Schema_uri 2
2247 * resultCount parameter to Sort Response (Amendment 1).
2248 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2250 Support for SRW 1.0 over HTTP. This is an optional feature and
2251 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2254 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2255 on the same port. SRW SearchRetrieveRequests are mapped
2256 to bend_init,bend_search,bend_fetch,bend_close.
2258 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2260 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2261 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2263 ZOOM connections are SRW based if schem http is used for hostname
2264 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2265 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2267 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2268 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2269 distance=n, order=true/false, relation=le, prox unit=word. If
2270 n is omitted, distance 1 is used.
2272 Fixed problem with C compiler include path in wrong order.
2274 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2275 on Solaris. Patch from Ko van der Sloot.
2277 New MARC decode API. All new functions operate on a yaz_marc_t
2278 handle. The most important new functions are: yaz_marc_create,
2279 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2280 decode and destroy respectively. Decoder can produce formats
2281 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2282 include/yaz/marcdisp.h.
2284 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2285 to UTF-8, UCS-32, wchar_t or Latin-1.
2287 * Prototypes for yaz_iconv_-functions moved to separate header
2288 include/yaz/yaz-iconv.h.
2290 Make a few private functions 'static' in unix.c. This prevents
2291 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2293 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2294 are set when Init Response is received.
2296 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2297 but returns diagnostic set as well.
2299 New function yaz_strerror which is a portable wrapper for
2300 strerror/strerror_r/GetLastMessage.
2302 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2303 is returned for MARC. If type is "oai", then OAI MARC is returned.
2305 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2308 --- 1.9.2 2002/11/26
2310 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2312 Fix bad race conditions on SIGTERM and terminate gracefully in
2315 Move retrieval (data1) module to Zebra since nobody seems to be
2318 Add GRS-1 render for ZOOM using same format as yaz-client.
2320 --- 1.9.1 2002/10/05
2322 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2324 Fix broken ESpec handling in data1 module.
2326 SGML reader parses comments and makes them part of the data1 tree.
2328 Added several type casts so that YAZ compiles as C++ code.
2330 ZOOM didn't handle PDU encoding failures properly.
2332 Added more Bib-1 diagnostics (approved extensions).
2334 GNU configure: better check for iconv.
2336 More portable use of accept, getpeername. Check for socklen_t. Use
2337 int/size_t if socklen_t is not defined.
2341 PQF parser rejects bad queries - including those with extra
2342 characters in them. PQF parser used to silently ignore that.
2343 Cleaner API for PQF added, which allows you to get detailed
2344 error information for bad queries (see yaz/pquery.h).
2346 Fixed bug in ZOOM_record_get for type "database".
2348 Implemented mini iconv library supporting conversions between
2349 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2351 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2353 --- 1.8.9 2002/08/20
2355 Fixed ZOOM C record cache so that preferredRecordSyntax and
2356 elementSetName is used to check for already fetched records.
2358 --- 1.8.8 2002/08/02
2360 Added three members in bend_initrequest structure to facilitate
2361 character set negotiation.
2363 Fixed a bug in frontend server that could cause indefinite
2364 loops under rare conditions.
2366 Revised character set utilities (charneg.h) so that encoding
2367 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2369 For PQF, directive @term <type> sets term type for Scan/Search.
2370 Here <type> is general, string, numeric, null. The term type
2371 is inherited - just like @attr.
2373 New call odr_set_charset that sets character set conversion for
2374 international-strings on a ODR stream. Prototype is:
2375 int odr_set_charset(ODR o, const char *to, const char *from);
2376 The InternationalString is still represented as C string in YAZ
2377 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2378 won't). On the protocol level, you can use any encoding.
2380 Support for UNIX sockets in ZOOM.
2382 Solaris recv sometimes returns errno == ENOENT. It is treated as
2383 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2385 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2386 both client and server. Code by Morten Bogeskov.
2388 --- 1.8.7 2002/05/22
2390 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2391 that they can be used directly from Visual Basic. You must recompile
2392 your windows APP if you're using ZOOM.
2394 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2395 Commands "lang" and "charset" sets language and character set respectively.
2396 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2397 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2399 Attributes from multiple CCL fields may be OR'ed rather than merged
2400 using directive "@field or". Fields are still merged by default -
2401 equivalent to "@field merge".
2403 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2406 Fixed bug in zget for parameter ExtendedServicesResponse.
2410 --- 1.8.6 2002/03/25
2412 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2414 Client displays USR.1:SearchResult-1 (hits per term).
2416 Additional Search Info for search in Generic Frontend Server.
2418 Fixed CCL parsing of "field=s".
2420 WIN32 installer - using the excellent NSIS software from nullsoft.
2422 Fixed CCL parsing of "field = - <number>".
2424 Added function yaz_marc_decode that decodes MARC for line mode
2425 display or XML (similar to that used by JZKit).
2427 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2428 Z39.50. But ISO/ILL was, however.
2430 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2431 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2433 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2434 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2436 --- 1.8.5 2002/02/03
2438 New YAZ client features: Command completion and new commands:
2439 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2440 Code provided by Jacob Poulsen.
2442 New call oid_trav, that visits all registered OIDs via callback.
2444 Function ZOOM_record_get now returns const char pointer rather than
2445 void pointer. It saves a lot of type casts.
2447 For YAZ client, command "auth" now allows you to set authentication
2448 in IdPass style. It is enabled when three tokens are given - order
2449 is user, group and password.
2451 Fix memory leaks in MARC record handling for ZOOM.
2453 New option for YAZ client, -k <kilobytes> that sets
2454 maximum record size. Similar to -k option for generic frontend
2455 server and yaz-ztest.
2457 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2459 Prefix query parser reports "fail" when bad attribute set is given.
2461 Fix in MARC decoder. Proximity logging. Fix for attribute set
2462 in scan handler for server. Patches by Shigeru Ishida.
2464 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2467 Configure option --with-openssl=<dir> now works when a directory is
2468 specified. Patch provided by Morten Bogeskov.
2470 New option for YAZ client, -u <auth>, that sets authentication.
2472 ZOOM fix: error information was sometimes "missing", since error
2473 was cleared/reset too when it shouldn't.
2475 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2477 --- 1.8.4 2002/01/04
2479 Scan for ZOOM API. New object ZOOM_scanset. New functions
2480 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2481 ZOOM_scanset_destroy.
2483 New ZOOM function, ZOOM_connection_last_event, that returns type
2484 of last event (such as "receive data", "send data", "apdu received",
2487 New ZOOM option, schema, that specifies schema for retrieval.
2489 New CCL feature. Qualifiers can be aliases for one or more
2490 other qualifiers (if more than one is given, OR is used).
2492 ZOOM uses named result sets if target supports it.
2494 Two new YAZ client commands: . (dot, which sources a script of YAZ
2495 client commands), and ! (to execute shell command.). Implemented
2498 Working on Debian packages.
2500 --- 1.8.3 2001/11/19
2502 YAZ client enables named result sets only if target supports it.
2504 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2506 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2507 with key="host" to get same result.
2509 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2510 Function Z3950_resultset_record(s) returns references to records
2511 "owned" by resultset. To become owner use Z3950_record_clone.
2513 Function z_ext_record handles Extended Services. Thanks to
2516 --- 1.8.2 2001/11/12
2518 CCL Parser fix: ignore token comma when dealing with and-lists.
2520 Documentation updates for COMSTACK.
2522 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2523 Changed prototype Z3950_records. For some functions, int parameters
2524 were changed to size_t.
2526 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2529 New MARC decode/display function, marc_display_exl, which properly rejects
2530 non-ISO2709 records. YAZ client uses it.
2532 --- 1.8.1 2001/10/29
2534 Fix bug: local attribute set wasn't set correctly in PQF strings.
2538 * Old Z39.50 codecs no longer supported.
2540 Added ZOOM C binding. See http://zoom.z3950.org/
2542 Renamed states for COMSTACKs to avoid confusion with events.
2544 Implemented cs_look and proper cs_rcvconnect.
2546 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2548 Configure detects POSIX threads on OpenBSD.
2550 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2551 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2553 When error is returned from present handler, non-surrogate diagnostic
2554 is returned in present response (and fetch handler is no longer called).
2556 * Minor adjustments to pquery parser (PQF). Token characters may be
2557 escaped by using backslash (C-style).
2559 PQF parser allows string attribute values to be specified. For @attr,
2560 non-numeric characters after the equal-sign are treated as strings
2561 (e.g. @attr 9=title).
2563 CCL trunction character may be defined (@truncation in file)
2565 * function zget_ExtendedServicesRequest sets waitAction to
2566 waitIfPossible (was wait).
2568 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2571 CCL operator names may be set in field definition files (CCL_bibset).
2572 See ccl/bib1 for an example.
2574 Fixes in ASN.1 compiler for C++ compatibility.
2576 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2577 and "op_or" to avoid conflict with C++.
2579 Fixed problem with GNU readline detection on Redhat 7.0.
2581 Added step-size for Scan backend handler.
2583 Fixed bug that made the frontend server crash when no attribute
2584 set was specified for scan.
2586 Front-end server automatically switches to original working directory
2587 when installed as an NT service. Previously -w had to be specified to
2590 Added extended attributes for retrieval module (data1), so that data1
2591 records carry d1_readXML/SGML attributes. d1_read also supports
2592 null-data rules ( <tag/>)
2594 On UNIX when POSIX threads are available, a separate library libyazthread
2595 is created. Programmers should link with that library and the yaz library
2596 when using threads. The reason for the split was that some applications
2597 on Linux, such as Apache, doesn't work well when using shared objects that
2600 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2601 (or any frontend server) in SSL mode by specifying ssl: followed by
2602 address. Only tested on UNIX.
2604 Added feature for CCL module. Virtual structure s=al or s=ol generates
2605 and-list and or-list respectively instead of phrase search.
2609 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2610 log_mask_str. This was done to avoid name conflicts with other libraries
2611 (such as other PHP extensions).
2613 Added raw OID member for preferred record syntax (request_format_raw)
2614 and returned record syntax (output_format_raw) for backend fetch method.
2616 Config file yaz-config now accepts options so that it returns specific
2617 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2619 Shared library support for UNIX using GNU libtool.
2621 * Modified backend interface. Request/Response struct's replaced by
2622 one read/write C struct. For example bend_fetchrequest and
2623 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2624 Every handler - even search has to be registered in bend_init
2625 handler. This means that the YAZ library no longer refers to
2626 external functions and it makes it possible to make the whole
2627 thing a single DLL/SO.
2629 Added Segment handler for backend server.
2631 Added Zmbol/Zebra administrative functions to YAZ client.
2633 Threaded frontend server on UNIX (when POSIX Threads are available).
2634 Starting the server with option -T enables multi-threading.
2638 Added configure option --enable-comp/disable-comp to control use
2639 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2640 located in sub directory asn.
2642 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2643 in ${exec_prefix}/bin along with the other programs yaz-client and
2646 GNU automake used to maintain makefiles.
2648 Added several OID's.
2650 Changed retrieval module so that we can load records with no abstract
2651 syntax defined. Tagpaths in these records are fully composed of string
2654 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2658 On UNIX, the generated makefile now supports a proper 'make install'.
2659 The prefix can be set via GNU configure to set the install location
2660 (default is /usr/local).
2662 * YAZ programs client and ztest were renamed to yaz-client and
2663 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2664 locations, such as /usr/bin,/usr/local/bin,etc.
2666 * YAZ Header files were moved from include to include/yaz. YAZ Header
2667 files are referred to as include <yaz/log.h> rather than <log.h>.
2668 The YAZ include path (-I ..) is therefore the same as before. Programmers
2669 should update their #include statements or use -Ipath/include/yaz
2670 instead. The main motivation for doing this change is that YAZ header files
2671 can be installed in "standard" locations /usr/include,/usr/local/include
2672 without introducing conflicts, since ALL YAZ header files are stored
2673 in subdirectory yaz (under /usr/include for example).
2675 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2676 rather than project/workspace files. We switched because project files
2677 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2680 Changed name of logging function, logf, to yaz_log, to prevent name
2681 clash with some math-log functions. The YAZ header log.h defines logf
2682 to yaz_log (#define) so there should be no incompatibilities by this
2685 Added bend_start/bend_stop handlers for server. These handler are
2686 called on start/stop of server. For windows they are called whenever
2687 a service is started/stopped.
2689 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2690 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2691 in util/yc.tcl. The auto-generated C code structures are, in a few
2692 cases, incompatible with the old decoders. There are differences in the
2693 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2694 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2695 The preprocessor variable ASN_COMPILED is defined when the compiled
2696 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2697 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2698 wish to use the old encoders/decoders you can specify --disable-yc
2701 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2702 version so that it supports both new - and old version of DB Update
2704 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2705 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2706 change. The name parameter can be set to 0 in which no name is specified
2707 for the construction. The macros odr_implicit and odr_explicit sets name
2708 parameter to zero for the construction involved. New macros
2709 odr_implicit_tag and odr_explicit_tag are similar to the others,
2710 except that a name parameter is added. For programmers' that don't use
2711 ODR they probably only need to change the call to z_APDU and z_External.
2713 Added access control facility by interfacing the TCP wrapper library.
2714 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2715 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2716 name of the daemon and enables the access control as specified in
2717 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2719 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2720 den Dool <H.M.vdnDool@kub.nl>.
2722 Added reference ID parameter to most functions in server API - refer
2723 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2725 Changed name of ccl library to libccl.a (was ccl.a).
2727 Fixed bug in decoder for Explain (Category TargetInfo).
2729 Added support for GNU readline in client. Thanks to Jacob Poulsen
2730 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2732 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2733 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2734 IMPLEMENTATION! This change was made to the development version before
2735 the ZIG decided to retract the amendment. If any users MUST be
2736 compatible with the original Update definition, PLEASE CONTACT US, and
2737 we will include a separate definition corresponding to the old Update
2738 ES. Note that because of the change to the ASN.1 of the
2739 TaskPackageRecordStructure we cannot define a single structure that
2740 will support both versions.
2742 * Added const modifier to buffer parameter for some ODR/BER encoding
2743 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2744 completeWAIS, odr_dumpBER.
2746 Fixed bug in client.c which caused a crash when a scanResponse didn't
2747 contain positionOfTerm.
2749 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2750 * will cause an error in a client if a non-YAZ target sends both a
2751 * list of Scan entries and non-surrogate diagnostics.
2753 Retrieval module enhancements. Tag sets may be typed in the reference
2754 to it. From the .abs-file the "tagset" directive takes a third optional
2755 integer type for the tag set referenced. From a .tag-file the "include"
2756 directive takes a third optional type as well. The old "type" directive
2757 in the tag set itself is still recognized but acts as the default type
2760 Backend interface change. Individual Scan terms returned from bend_scan
2761 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2762 in include/backend.h.
2764 Retrieval module enhancements. Multiple tag sets and attribute sets may
2765 be specified in abstract syntax specs. Revised the error/warning for
2766 logging messages reported by the retrieval module when reading the
2769 Object Identifier system (oid_..) changed. The API is backwards
2770 compatible but the oid-routines now allocates new OID's when needed.
2771 Raw OID's may be specified in oid_getvalbyname.
2773 YAZ now uses GNU configure to generate Makefile(s).
2775 * Minor changes in some of the member names of DeleteResultSetRequest and
2776 DeleteResultSetResponse. See include/proto.h.
2778 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2779 and added member 'languages' in TargetInfo (which was missing).
2781 Changed the way attribute sets are handled in the retrieval
2782 module. These are now cached, just like the abstract syntaxes
2785 Changed YAZ so that it links with compiled ASN.1.
2787 Added Explain-schema definitions and mapping routines. The following
2788 Explain categories have been implemented: AttributeDetails,
2789 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2791 Fixed minor bug in Windows version of Server Library.
2793 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2795 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2797 Added EXTERNAL: UNIverse Resource Report (non-standard).
2799 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2800 ENUMERATED and SET OF.
2802 * Added 'const' to some of the char pointer arguments for the
2803 functions, data1_read_node, data1_getelementbytagname,
2804 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2807 Fixed bug in data1_insert_taggeddata - the last_child member of
2808 parent wasn't initialised.
2810 * Changed data1_read_record and data1_read_node so that the supplied
2811 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2812 doesn't refer to any parts of the "SGML"-buffer.
2814 Fixed bug in server library (Windows version of statserv_remove).
2816 * Changed code so that it compiles as C++. The type definition
2817 of Odr_fun which is a member of Odr_arm was changed. The result is,
2818 that an explicit typecast is needed for the fun pointer when
2819 using Odr_arm - as in:
2820 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2822 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2824 Implemented the new structured date and time definition as approved
2825 by the ZIG. Added schemaId element to the specificTag in Espec-1
2826 (also approved at the last ZIG). Thanks to RVDM.
2828 Added some Object identifiers (RVDM).
2830 Changed the Update Extended Service (RVDM).
2832 Added command "refid" to client which specifies referenceId for
2833 the following requests.
2835 Implemented extended service handling for server. See ztest.c
2836 for an example as well as backend.h. New handlers are registerd
2837 in the Init handler.
2839 * Changed interface for sort in server.
2841 Added new members to statserv_options_block. It allows a server
2842 to read options from another source than just the command line. Thanks
2843 to Charles Woodfield.
2845 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2846 renamed to zboolean. Some C++ compilers complained about the name.
2848 Minor changes to gils.abs. Added index 's' (sort) on title
2849 and date/time-last-modified.
2851 --- 1.4pl2 1998/1/30
2853 Fixed bug in server library regarding inetd mode (-i). This bug
2854 was introduced by release 1.4.
2856 --- 1.4pl1 1998/1/29
2858 Added sort facility in client and backend server interface.
2860 Fixed problem with dependencies in Makefile(s).
2862 Fixed bugs for encoders/decoders of extended services and
2865 Implemented sub-tree feature for schemas. Sub-trees are
2866 referenced in *.abs-files. See explain.abs for an example
2867 of the use of this feature.
2869 Modified bib1.att; local attributes for ANY didn't include
2870 ANY itself (only affects use of the retrieval module).
2872 Fixed bug in plain SGML reader in function data1_read_node:
2873 tags with prefix "var" was incorrectly interpreted as variants.
2875 Added feature "sub-schemas" to enable references to - and definitions
2876 of - group of elements.
2878 * Removed member parent from type data1_element (in data1.h).
2880 Implemented function odr_nullval() that returns the value of
2883 * Removed member num_children from data1_node (in data1.h).
2885 Made NT service interface part of the server library. The
2886 function statserv_main uses the NT service when required and
2887 calls the statserv_start / statserv_close routines.
2889 Routine zget_SearchRequest and zget_PresentRequest fills
2890 resultSetName/Id member with "default" instead of "Default".
2892 Fixed memory leak in server. Request queue member wasn't freed.
2894 Fixed nmem_exit so that memory is freed.
2898 Revised the CCL parser utility to be thread safe.
2900 Added function, oid_ent_to_oid, to replace the function
2901 oid_getoidbyent, which is not thread safe.
2903 * Added nmem_init and nmem_exit to initialize and release
2904 NMEM resources. Function nmem_init should be called once in the
2905 initial thread before NMEM/ODR is used. statserv.c and client.c
2906 have been changed accordingly. The change was necessary to make
2907 NMEM thread safe. The NMEM memory pool is shared amongst threads
2908 in a process. Unix-based applications will still work fine without
2911 Added NT Services interface for the the Z39.50 (statserv) Server.
2912 Refer to the ztest.c source on the usage.
2914 Windows 95/NT port using MSVC5.0. Project files are included in the
2917 * Defined new 'global' handle for the retrieval (data1) system. The
2918 new handled, data1_handle, describes the state of the data1 system.
2919 This handle is passed as first argument to virtually all
2920 data1 related routines. The functions data1_create and data1_destroy
2921 creates and destroys a data1 handle respectively.
2923 Added ODR encode stream member to all backend request structures
2924 init, search, scan etc. This stream should be used to allocate all
2925 memory used for the response when thread safe operation is needed.
2927 Changed the comstack utility, cs_addstr, to be thread safe. The
2928 returned hostname string returned by the function is now part the
2931 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2932 function. The cs_straddr takes a COMSTACK handle as argument, so this
2933 function must be used after cs_create and before bind/connect.
2934 This function is thread safe.
2936 Moved test server to 'ztest' directory - generic server code still
2937 in 'server' directory.
2939 Made prefix query (pquery.c) utility thread safe.
2941 Added new function modifier YAZ_EXPORT to 'export' public DLL
2942 functions when using windows (see include/yconfig.h).
2944 Added definitions to the OID database (util/oid.c) (RVDM).
2946 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2948 Added call to ccl_rpn_delete in client program.
2950 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2951 release of RPN structure.
2953 Added support for C++, headers uses extern "C" for public definitions.
2954 With input from RVDM.
2956 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2957 Thanks to Ronald van der Meer (RVDM).
2959 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2961 Added support for private extensions to the OID database
2962 (oid_setprivateoids()). Thanks to RVDM.
2964 Added optional, physical ANY (key replication)
2966 Fixed null-reference problem in GRS-1 output filter.
2968 Proximity operator added to Prefix Query Format (PQF).
2970 In test client command "base" accepts multiple databases.
2972 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2976 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2978 Smallish bug-fixes in the new encoders/decoders (explain).
2980 Bug fixed in DeleteRequest.
2982 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2984 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2986 Added SOIF syntax (using private OID for now) to retrieval module and client.
2988 Added Update extended service.
2990 Added SearchResult-1 additional info structure.
2992 Added optional CCL (ISO8777) interpreter as separate module. Available
2995 --- 1.2 1996/6/10 (1st anniversary release)
2997 Added Summary record syntax. Lightly tested.
2999 Added OPAC record syntax. Untested.
3001 Added ResourceReport service encoders/decoders. Untested.
3003 Fixed bug in z_Unit - wrong tagging on unitSystem.
3005 Fixed bug in the DiagRecs decoder.
3007 Added options for max PDU size and session timeout to frontend-server.
3009 Added documentation of query-language parsers and other supporting utilities.
3011 [frontend-server] Added Attribute set to the bend_scanrequest API.
3013 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3014 surrogate diagnostics were generated.
3016 [retrieval] Allow multiple local values for attribute.
3018 [retrieval] Allow multiple attributes per element in .abs files. index type.
3020 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3022 --- 1.1pl2 1996/4/10
3024 Minor changes, mostly specific to Zebra's requirements (retrieval)
3028 Repaired bug in frontend server when running multiple listening
3029 endpoints in dynamic mode.
3031 z_External() now won't break if a known, ASN.1 value comes encapsulated
3032 in an octet-string. The value will pass through unmodified in an Odr_oct.
3034 Added a bit of code to the demo client to decode & display
3035 ASN.1-structured records represented in the octet-aligned branch of
3036 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3038 Added z_ext_getentbyref() to the ASN module. Doc updated.
3040 * Completed the SCAN definition in the ASN module. This may break SCAN
3041 code based on older YAZ-versions at compile-time. The fix is easy -
3044 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3045 under the SCAN definition. Remember to initialize this, server-people.
3047 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3048 that this does not extend to ODR and ASN.
3050 Comstack allows insertion of established socket (primarily for
3051 inetd-operation of servers). Doc updated.
3053 Front-end server can now start from the inetd in TCP mode. Doc
3056 --- 1.0pl4 1996/1/24
3060 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3061 the rank and record number.
3063 Adjustments to the frontend server.
3065 Fixed diagnostic BER dumper. It ignored the file argument.
3069 Various changes to retrieval module.
3071 Changed the union discriminators of the protocol files from enums to
3072 ints paired with #defines.
3074 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3077 *Changed operator in the RPN structure to 'roperator', again to avoid a
3080 Fixed problems in Explain decoders/encoders.
3082 --- 1.0pl2 1995/12/6
3084 Memory bug in log module fixed.
3086 --- 1.0pl1 1995/12/5
3088 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3090 Bug in Explain DatabaseInfo module fixed.
3092 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3096 The shift to v1.0 signals that we now consider the *core* functionality
3097 of YAZ reasonably stable (the core being more or less equivalent to
3098 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3099 tested (Explain not at all - though that will happen soonish).
3101 Minor changes to code to support Windows port.
3103 Various minor changes after we're getting to use GRS-1 & co. more.
3105 Added Espec-1 format.
3107 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3108 of the protocol and it cannot be selected when encoding (maps into 'string'
3109 when decoding). Needed to talk to some servers.
3111 Demo client can request simple element set names.
3113 Added Diagnostic Format encoders/decoders.
3115 Added simple Close handling to frontend server (no hooks for resource
3116 reporting yet), and demonstration client.
3118 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3120 --- 1.0b3 1995/08/24
3122 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3123 handled incorrectly when records were requested in the searchResponse. This
3124 will only affect you if you use the frontend-server.
3126 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3127 Test-client will ask for and print GRS1. Ztest will return dummy records
3130 Added Explain encoders/decoders to the service-level API. Untested.
3132 Added Extended Services: Item Order encoders and decoders to the Service-
3133 level API. Untested. We could use a recent copy of the pertinent bits
3134 of the ILL protocol to add those bits.
3136 Added diagnostic format 1 encoders/decoders to the service-level API.
3139 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3140 odr_cons.c, which causes a more correct output.
3142 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3143 was always set to 0 when no records were requested in the searchRequest.
3145 * Added better external-handling. This shouldn't harm old code that
3146 *encodes* externals. It can break code that looks for a
3147 'single-ASN1-type' representation, since those types that are known
3148 are now decoded immediately. Look at the SUTRS sample code in
3149 seshigh.c and client.c. Documentation updated.
3151 Handling of structured records in bend_fetchresponse. Length -1 marks
3152 structured record, type is deduced from format field.
3154 --- 1.0b2 1995/06/27
3155 Fairly quick maintenance release to add SUTRS support.
3157 Fixed handling of SUTRS records in the demonstration client.
3159 * Added format field to the bend_fetchrequest and bend_fetchresponce
3160 structures of the backend API (frontend server). When the record is
3161 returned, the value of the format field is mapped to an OID. The
3162 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3163 of the record. The special value VAL_NONE in the bend_request means
3164 that no specific format was requested by the client. Documentation
3165 updated accordingly. Test server (ztest) will return a fixed dummy
3166 SUTRS record if your client requests SUTRS.
3168 Documentation updated accordingly.
3170 You can now set external libraries and RANLIB support in the top-level
3174 First public release.
