3 fix problem with record_render: records were converted (character set
4 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
8 SRU: add methods for handling DADS SRU-proxy facets.
10 Separate OPAC record character set for ZOOM_record. yaz_record_render
11 allows a character set given as charset=from/opacfrom,to where 'from' is
12 the character set of a bibliographic record, 'opacfrom' is character set
13 of OPAC record and 'to' is the target character set.
17 yaz-client: show may XML format records. Command show followed by 'format'
18 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
21 src/stemmer.c: Avoid using unnamed union. It is not supported by some
24 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
27 Update yaz.spec to operate on both SLES11 / Centos 5.5.
29 RPM: Release includes 'indexdata' name. Use indexdata in release name so
30 this package can be distinguished from other vendors.
32 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
33 as determined by configure
35 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
37 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
38 returns no error and no record, the present request is considered
39 partial (only a subset of the records could be returned by backend), and
40 so it is appropriate to set Present Status to partial-4.
44 Move yaz-config man pages to section 1.
46 More documentation about SOLR.
48 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
49 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
50 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
51 peers on some Linux systems. However, in general that does not work
52 so YAZ can not rely on that to work. Debian changed behavior in this
53 respect from Debian lenny to Debian squeeze (still testing as of Oct
55 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
57 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
61 Fix yaz-config output: echo_source not set correctly by configure.
65 SOLR WebService support for yaz-client and ZOOM.
67 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
71 Z39.50 facet support. Facet specifications are passed for search in
72 other-information with ASN.1 as defined in facet.asn and OID
73 .10.1000.81.5 . Facets are expressed as an Attribute list as known
74 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
75 3 is limit (number of entries to get in response). yaz-ztest returns
76 dummy facets if a client asks for them.
80 CCL fixes: bug 2895 and bug 3539.
82 GR1-display: add comma in display - was removed by mistake in
85 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
87 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
91 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
92 result set from a connection. The result set will be on its own
93 thereafter; no operations on it will perform retrievals from a target.
94 Only cached copies are returned.
96 ZOOM C:fix case for HTTP servers responding with Connection:close.
97 Ensure that if there is a current task it is resumed (like fetching
98 more records in a result set) . Bug #3484.
100 PQF parser: use odr_atoi for Odr_int (not atoi)
102 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
103 values that contain any non-digits are treated as string attributes
104 (previously decoding only checked for leading character ([0-9]). PQF
105 encoding: attribute string values are not surrounded by double-quotes.
109 New utility for managing threads - thread_create.h.
111 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
112 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
113 but YAZ' implementation do.
115 Fixes for yaz_cond-functions on Windows 7.
117 DLL export more symbols.
119 zoomsh: show record do NOT render opac.
121 Remove *.la files from Debian and RPM packages.
125 Debian package libyaz-dev depends on libgnutls-dev again (was
126 removed in YAZ 4.0.6, but due to Libtool it is still needed
127 even though yaz-config do not list libgnutls libs).
129 ZOOM: Use only one WRBUF for returning string results for
130 ZOOM_resultset. Reduces memory usage for ZOOM in general.
132 ZOOM: ZOOM_connection do not use a shared pointer to
133 ZOOM_resultset after ZOOM_resultset is destructed by
134 user. Reverts to YAZ 4.0.4 behavior.
138 record-conv: fix problem with at least one XSL conversion -
139 due to probably incorrect usage of XML XSL documents.
143 Fix yaz-config for static mode and the use of SSL (gnutls).
147 Forward decl timeval struct in mutex.h and gettimeofday.h.
149 yaz-config: fix 'static' mode linking.
153 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
154 are wrappers for pthreads or Windows. For Windows these are put in
155 a separate DLL: yaz_cond4.
157 libyaz.la (whole source) is compiled with thread. If thread support
158 is enabled enabled, all source of YAZ is compiled with treading support.
159 This allows core utilities such as yaz_log to use thread facilities.
160 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
161 thread utilities. This commit moves mutex utilities (mutex.c) from
162 libyaz_server.la to libyaz.la.
164 yaz-json-parse displays leading text until error.
168 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
169 patch from Giannis Kosmas.
171 SRU: no longer URL encode SRU database. The URL for an SRU server is
172 a URL and such is alreeady encoded - at least when given with leading
173 http:// or https://. This reverts behavior to YAZ 3.0.50.
175 Support for new MARC XML notation TurboMARC which like MARCXML is a
176 complete representation of MARC/ISO2709.. This one, however, is more
177 compact and allows for faster processing with XSLT. TurboMARC can be
178 used in the marcdisp.h API, from the yaz-marcdump utility and from
181 yaz-ztest can be configured - via the database - to perform certain
182 delays when it performs operations search, present and single record
183 fetch. This allows testers to make yaz-ztest act as a real or even slow
184 Z39.50 server. Refer to the yaz-ztest man pages for details.
188 wrbuf_destroy allows NULL WRBUF passed to it.
190 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
192 Add ZOOM_connection_close.
194 No fixed size buffers for ZOOM shell - bug #3257.
196 tstodr: make it work on s390 platform.
198 New icu iterator-functions. The new icu_iter-functions makes it possible
199 to use ICU chains from many threads.
201 yaz-client: better syntax check for show command.
205 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
208 New simple local-file XML include facility which allows file glob-patterns.
209 Refer to yaz/xml_include.h.
211 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
214 ZOOM_record_get supports new parameter "format" which makes it format XML
217 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
218 JSONText in ECMA-262) is JSONValue, not JSONObject.
222 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
223 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
225 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
226 POSIX/Unix builds .so with major version 4.
228 Remove old LOG_-defines from log.h. They have been obsolete and
229 undefined by default for the last 5 years.
231 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
233 GFS: Remove socket (int *fd) from search_rr handler. The socket
234 descriptor ptr is a facility that allowed a search handler to supply
235 a socket which would serve as a callback - when search was complete.
236 This facility has now been in use for years.
238 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
239 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
240 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
241 returns 'const char *' rather than 'char *. The returned string is
242 read-only and should not be modified by applications. COMSTACK cs_close is
243 now a void function - it no longer returns int. No applications check for
244 the value and the implementations has always returned 0.
246 ZOOM: use size_t for scan hit counts and str size. Functions
247 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
248 occ (hit count) and len (string length) are now of type size_t pointer
249 rather than int pointer. This is to be able to represent large hit counts
250 and to also just to use the proper type for string length (strlen result).
252 New JSON parser. Refer to include/yaz/json.h .
254 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
255 Used to be int in some cases. Many wrbuf_-functions used to return an int
256 indicating some length.. These return values were never used. And so they
259 ODR: odr_malloc, odr_total now takes size_t for size.
261 clone_z_type: fix leak; occurred for encoding failures.
263 --- 3.0.52 2009/12/03
265 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
266 bug was introduced in 3.0.51.
268 --- 3.0.51 2009/12/02
270 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
272 tcpip comstack: fix leak for getaddrinfo.
274 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
275 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
276 Decoding of SRU "path" database is performed by private function
277 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
278 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
280 yaz-client: honor base command for SRU. Change when database setting
281 is applied for SRU and ensure it is kept when a connection is reset.
282 Change also the way errors are displayed or SRU (decoding of packages).
284 --- 3.0.50 2009/11/02
286 Add support for extra request / response data for SRU codecs and GFS.
287 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
288 for extra data response buffer and length. For the GFS, both request
289 and response data (XML) is carried in extra_args and extra_response_data
290 for the search handler. Patch by Ko van der Sloot.
292 ZOOM: For queries that cannot be converted to the specified rpnCharset,
293 ZOOM now returns a diagnostic on the client-side ('invalid query' /
294 10010). This fixes bug #2113.
296 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
297 cmdfile included a 'quit' command that would result in a memory violation.
299 --- 3.0.49 2009/10/01
301 Make a number of functions defined in xmlquery.c static. These have
302 never been declared in a public header file (yaz/xmlquery.h) and was
303 made public by mistake.
305 Improve speed of character conversions (iconv utilities). This makes
306 conversions from MARC-8 faster.
308 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
309 unless type desired is "raw". This will prevent type "xml" from
310 returning ISO2709 .. Which obviously can not be XML parsed.
312 Fix memory leak in ZOOM that would occur if option apdulog was used
313 on a re-used connection.
315 Frontend server logs HTTP requests.
317 Frontend server now sends Z39.50 close when it times out (sesssion has
318 been idle for too long). Versions 2.0.30 and earlier also sent close.
319 But due to a mistake this was disabled in all versions after that, i.e.
320 the server would just close the socket immediately.
322 yaz-client emits a better message when receiving an unrecognised
323 userInformationField.
325 Skip zero-length subfields when decoding ISO2709. This rare case happens
326 if a record has two FS characters in a sequence. Without this patch
327 there would be a reference beyond char array in using_code_len fragments
330 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
332 --- 3.0.48 2009/08/28
334 The show command offered by the zoomsh command now takes a 3d optional
335 parameter type which is what is passed to ZOOM_record. If the type
336 argument is omitted, "render" is used.
338 RPN to CQL conv may use USE string attributes (bug #2978).
340 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
342 --- 3.0.47 2009/07/08
344 Function yaz_xml2query allows a diagnostic element in the PQF XML
345 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
346 code and additional info respectively.
348 The BER BOOLEAN is now the integral type Odr_bool which still happens
349 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
350 typedef'd to Odr_int. This is still an integral 'int', but it may be
351 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
352 ASN-1 compiler as well as programs has been updated to use the new types.
354 --- 3.0.46 2009/06/08
356 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
357 only the bibliographic record was rendered. For type=opac, an OPAC
358 record is only returned if it is present.
360 iconv: small fix for encoding of advancegreek.
362 yaz-client: avoid double display of SRU/SRW records (bug #2798).
364 yaz-client: option auto_reconnect=on really reconnects.
366 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
368 server: avoid null ptr ref for for yaz_poll errors.
370 build: fix RPM build for RHEL 5.3.
372 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
374 --- 3.0.45 2009/03/31
376 Fixed bug #2709: TCP connect returns Invalid argument.
378 Fixed compilation for mingw.
380 Honor charset for raw records (ZOOM_record_get).
382 Fixed use of errno for threaded mode that was seen on Solaris 10.
384 Fixed argument passing with blanks in value for Windows Service.
386 Disable YAZ' own log rotate by default (no 1 GB limit).
387 The variable l_max_size which specifies the log file limit is set to 0
388 (DISABLED): This is due to the fact that YAZ is most often deployed using
389 logrotate. Also YAZ can not perform log rotate because of unsufficient
390 permissions (setuid).
392 --- 3.0.44 2009/02/17
394 List supported encodings in man page for yaz-iconv.
396 Fixed missing SSL libs for --libs output
398 Re-established OID record syntax application-xml. Nobody should use it
399 but we don't want to change soname because of this symbol being absent.
401 --- 3.0.42 2009/02/02
403 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
405 Added member named_result_sets for init handler struct for the GFS. This
406 allows a server to disable named result sets.
408 Removed OID record syntax application-xml.
410 Added support for rule-based transliterator for ICU wrapper of YAZ.
412 Fixed bug #1902: yaz-icu XML output.
414 Make YAZ checks Emacs friendly.
416 BITSTRING value shows value. Bug #2346.
418 ISO2709 decoding: skip control characters from indicator data.
420 Omit sort key by default in yaz-icu's output.
422 Allow combined single char options (again) for YAZ' options function.
424 Utility yaz-marcdump got option to display YAZ version (-V).
426 Allow YAZ to use ICU 3.4.
428 Added new ICU test case which illustrates removal of diacritics.
430 --- 3.0.41 2008/12/29
432 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
434 --- 3.0.40 2008/12/29
436 For configure, using option --without-xml2 also disables Libxslt/Libexslt
439 Fixed bug #2352: yaz-marcdump crashes for certain record.
441 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
443 Added support for Danmarc2 to UTF-8 conversion.
445 Added support for ISO5426 to UTF-8 conversion.
447 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
448 implementation version.
450 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
452 --- 3.0.38 2008/11/10
454 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
455 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
457 ZOOM C now interprets databaseName option for ZOOM connection as path
460 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
462 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
464 Dummy Libxml2 types no longer defined in headers of YAZ'.
466 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
469 --- 3.0.36 2008/09/26
471 Various ODR chapter fixes.
473 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
475 Added missing source for Windows compilation, mutex.c.
477 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
479 For SRU connections in ZOOM all records up to "count" are now fetched.
481 Fixed crash in generic frontend server (and yaz-ztest) which occurred
482 in Windows due to bad error handling for Libxml2.
484 Added facility for sending arbitrary records (ASN.1 any) using
485 ZOOM C's Extended service update. Patch by Sam Reynolds.
487 New options for ZOOM C's connection, logapdu which makes ZOOM log
490 --- 3.0.34 2008/06/18
492 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
494 --- 3.0.32 2008/06/12
496 Fixed memory violation that could occur when decoding UTF-8. This bug
497 was only present in 3.0.30 of YAZ.
499 --- 3.0.30 2008/06/06
501 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
502 GNU TLS is used by default (if found).
504 yaz-ztest returns OPAC records if a client asks for OPAC.
506 Improved speed of MARC-8 encoding.
508 Added support for lossy and loss-less MARC-8 encoding.
510 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
512 Added new Windows Service wrapper (sc).
514 yaz-client's itemorder command may now send a file.
516 Fixed yaz-marcdump to allow the use of NS prefix for record element.
518 Added new function yaz_log_xml_errors.
520 Allow (but warn) unknown XML attributes in MARCXML parsing.
522 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
524 The UTF-8 to MARC-8 conversion now uses a different set of characters
525 for Greek symbols. Bug #2120.
527 --- 3.0.26 2008/02/21
529 Added yaz_daemon (daemon.h).
531 Fixed bug #2068: pkg-config trouble
533 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
535 --- 3.0.24 2008/01/28
537 Document --with-xml2 option.
539 Added OPAC XML XSD (etc/opacxml.xsd).
541 Allow glob mask for name attribute in retrieval element for the
542 generic frontend server's retrieval facility.
544 Changed yaz_poll_poll to return yaz_poll_except for all returned events
545 except POLLIN/POLLOUT.
547 Fixed error handling in cs_listen. Bug #2037.
549 --- 3.0.22 2008/01/20
551 Fixed version in yaz/yaz-version.h.
553 Fixed bug #2027: Crash when closing connection.
555 Changed configure so that ICU support is only enabled if only ICU
556 and Libxml2 is available (because the ICU chain is XML based).
558 --- 3.0.20 2008/01/15
560 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
561 is built. Only this DLL depends on the ICU runtime.
563 yaz-ziffy is no longer part of YAZ. It is distributed separately by
564 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
566 Changed license of CCL module to 'Revised BSD'. After consultation with
567 remaining members of the original EUROPAGATE consortium, we are re-issuing
568 the CCL module without a separate license. The software was developed by
569 Index Data as part of a research project. The special license was included
570 to help feed usage information back to the project consortium to support
571 project evaluation. At this time, the project consortium has long-since
572 disbanded, and the majority of the original principals have retired. At the
573 same time, we have significantly modified the software during the following
574 years, to the point where very practically no original code remains. To
575 simplify re-use of the software, we have contacted those members of the
576 consortium who could be reached, and agreed to re-issue the module as a
577 proper part of the YAZ package.
579 Tcl scripts uses /usr/bin/tclsh as preferred shell.
581 CQL closer to being version 1.2 compliant. CQL also allows free-form
582 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
585 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
586 bug could make Extended services handling crash in the ZOOM layer. This
587 bug was only present in YAZ 3.0.18.
589 --- 3.0.18 2007/12/19
591 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
594 yaz-marcdump reads and writes collection wrapped records.
596 Handle OPAC for record conversion module.
598 Fixes for ICU wrapper.
600 Allow ICU libs to be controlled with --with-icu .
602 --- 3.0.16 2007/11/12
604 Added yaz_poll which is a wrapper for select/poll. When poll is available
605 and non-buggy, it is used, by yaz_poll . This allows more than 1024
606 sockets to be in use.
608 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
609 functionality through an XML based configuration (ICU chain). This system
610 is useful for search facilities such as Pazpar2 and Zebra that needs to
611 perform tokenization of indexed material. The ICU code in a separate
612 library libyaz3_icu.a.
614 Added HTTP tunnel facility for COMSTACK, bug #1752.
615 This is a facility that allows a Web proxy, such as squid, to tunnel
616 Z39.50 traffic. This facility is "transparent" to must applications
617 using YAZ. It's enabled by using pseudo transport connect: followed by
618 the proxy address, followed by command, then follwed by he regular
619 "virtual" addresss. For example,
620 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
622 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
624 --- 3.0.14 2007/09/21
626 Fixed bad memory reference in ZOOM_record - cuased by member not being
627 initialized. This was a problem only in YAZ 3.0.12.
629 Fixed bug in conversion from MARC to XML: Non-XML characters in control
630 fields were not removed.
632 Changed the way C code is generated from codetables.xml. Made a MARC-8
633 conversion trie for each characterSet section rather than codeTable.
634 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
635 of codetables.xml from Larry Dixson, LOC. Bug #1464.
637 --- 3.0.12 2007/09/12
639 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
640 from ZOOM_record_error).
642 ZOOM C function ZOOM_record_get returns record schema for type="schema".
644 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
646 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
648 Better SRW-to-Bib-1 diagnostic mapping.
650 ZOOM C and yaz-client announces SRU version 1.2 by default.
652 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
655 Fixed in yaz_sru_decode to allow other version than 1.1.
657 --- 3.0.10 2007/08/22
659 Added support for SRU scan for ZOOM.
661 Added support for the use of the older versions or Extended Service
662 Update in ZOOM. To faciliate this, an option "updateVersion" may be
663 set to the version , 1=first, 2=second, 3=third. The third version is
664 what ZOOM C has used so far. And that, obviously, is the default.
666 Added support for CCL queries in Z39.50 queries sent to the GFS (and
667 therefore in Zebra and in SimpleServer-based applications). The new
668 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
669 qualifier file used to transform incoming CCL queries into Type-1 RPN,
670 which is passed into the back-end search callback function.
672 Added support for HTTP Basic authentication in clients: the SRU/W
673 codec encodes the username/password elements of the PDU structure
674 appropriately, and these may be set using the "user" and "password"
675 options in ZOOM-C applications (the same options that are used for
676 Z39.50 authentication).
680 Fixed bug #1208: SSL appears to be broken in ZOOM.
682 Fixed bug #1206: Libxml2 include path weirdness.
684 Added oid_name_to_dotstring.
686 Allow elementSetName to be specified for ZOOM C record update.
688 Allow waitAction to be specified for ZOOM C based for Extended Services.
690 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
691 syntax OID. Bug introduced in YAZ 3 series.
693 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
697 Fixed bug #1157: yaz-client does not read .yazclientrc from current
698 directory. yaz-client now reads commands from file given by option -f
699 if specified; then tries to read .yazclientrc in current directory.
700 Failing that, it reads .yazclientrc from user's home directory.
702 Added support for correlationInfo Note and ID for Record Update via
705 Added yaz-client command querycharset which specifies character set for
706 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
707 (termListAndStartPoint).
709 Charset ISO5428:1984 is an alias for ISO5428-1984.
711 Implemented a way to perform scan in a result set using Z39.50. This
712 is achieved by attaching the result set name in the characterInfo
713 (type InternationalString) of OtherInformation in the Scan Request PDU.
714 The result set is identified in the otherinformation by the new OID:
715 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
716 This allows for scan in result set and faceted search . Zebra did some
717 of this in the APT term using attribute type 8 and value being result
718 set. Using the OtherInformation approach for this is cleaner and easier
719 to work with in proxies and the like. This facility can be used in
720 yaz-client using new command setscan which takes a result set as first
721 argument, start position (APT) as second.
723 Changed decoding of SRU XML packed records to deal with servers that
724 have recordData with XML data with multiple root nodes. Also make
725 comparison for recordPacking case insensitive. Again, one server
726 returns "XML" where others return "xml".
728 For SRU responses allow Content-Type application/xml as well as text/xml.
732 Fixed bug in character set conversion of BER strings. Bug introduced
737 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
739 For OID class, use oid_class consistently.
741 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
744 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
745 character set for bibliographic information interchange". By Giannis Kosmas.
747 Added documentation on new OID API.
751 Changes to generic frontend server interface: added new member
752 'query_charset' for bend_initrequest structure. A backend init handler
753 should set this member to its native character set for query terms.
754 When defined, the frontend server logic will announce this character set
755 to a client if the negotiationModel bit is set by the client. All server
756 implementors are encouraged to specify this. If a backend server does not
757 specify this a warning is issued using yaz_log(YLOG_WARN,..).
759 Added CCL utility to remove terms (stop words) from resulting RPN
760 tree. This is handled by functions with prefix ccl_stop_words_ .
762 New ZOOM C option, "rpnCharset", which allows client-side conversion of
763 terms in RPN queries.
765 Clean-up the CCL API. Moved some internal structures from ccl.h to
766 private header cclp.h. Changed ccl_parser_create so that a Bibset must
767 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
768 This is replaced by ccl_parser_find_str which takes a string instead.
770 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
771 libyaz.la is the core of YAZ except the generic frontend server and
772 does not depend on POSIX threads anymore. libyaz_server.la is the
773 generic frontend server facilities and uses POSIX thread functionality
774 if available. The libyaz.la no longer depends on POSIX threads because
775 the number of global structures is limited. NMEM no longer re-uses blocks
776 between threads ; it simply free's memory immediately but allocates in
777 "large" chunks as usual. We don't expect any performance penalties
778 because of this. The yaz_log system is still using a global log_level so
779 caution must be taken when modifying it with yaz_log_init_.. +
780 yaz_log_mask_str. This, however, should not cause any trouble because
781 these functions are called during initialization of application code
782 anyway. `yaz-config --libs server` returns libs for server applications;
783 `yaz-config --libs` returns libs for non-server applications.
785 New OID database - with public definitions in oid_db.h. Removed old OID
786 database including the head oid.h and definitions such as enum oid_value
787 and struct oident. The new OID database uses the same string names as
788 before but the 'protocol' is gone. There are now only two representations
789 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
790 converts from string to OID; functions with prefix yaz_oid_to_string
791 converts the other way.
793 Change to emit_term() in CQL-to-PQF query translation: when a term has
794 the /regexp relation modifier, do not process it for leading and
795 trailing "^" and "*", which have quite different meanings in regular
798 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
799 write handlers no longer carries a 'last' parameter. This will make
800 yaz_iconv flush "less" characters. A flush is performed by call to
801 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
803 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
804 removed, because function yaz_query_to_wrbuf does the same.
806 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
807 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
809 Deprecated MARC utility functions removed.
811 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
814 Branch split: YAZ_2_1_55_branch
816 --- 2.1.54 2007/03/16
818 Fix to ZOOM-C so that transparent reconnection is properly handled on
819 connections that are in asynchronous mode.
821 Fixed compilation on OpenBSD 4.0.
823 Large strings in GRS-1 records are now properly displayed in yaz-client.
825 Added character conversion support for "advancegreek"; based on patch from
828 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
829 sequence is met. Before the error was not set so it would be unknown.
831 Adjust yaz-marcdump MARC reader so that it skips until record separator
834 --- 2.1.52 2007/03/07
836 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
837 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
838 fd_set structure used as a bitmask for the FDs to be selected on.
840 Using ACX_PTHREAD macro to check for POSIX threads.
842 Fixed have-vsnprintf check.
844 --- 2.1.50 2007/02/23
846 Fixes for configure on BSD. Bug #900.
848 Added snprintf/vsnprintf wrappers for systems that don't have
849 limits (heavens forbid).
851 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
852 created before all previous tasks were completed and removed from the
853 task queue, the new task could be removed by a mistake.
855 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
857 Implemented pass-through CQL-to-PQF conversions. Bug #861.
859 Fixed bug #832: Problem with MARC/charset in yaz-client.
861 Fixed bug #668: save command line history for yaz-client.
863 Fixed bug #830: pkg-config support.
865 --- 2.1.48 2007/01/23
867 Extended ZOOM result set options with two options that may be read by
868 a client: resultSetStatus and presentStatus with values as specified for
870 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
872 Fixed bug #827: Using SSL fails on Debian etch.
874 Fixed bug #826: Weird looking chars for set of MARC records.
876 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
877 that is treated as an ItemOrder with itemRequest being an XML document
878 external. The value of "doc" is the content.
880 Extended the GFS search facility. New member of bend_search_rr
881 'estimated_hit_count' signals that hits is known to be an estmate
882 (higher or lower than real hit count). New member 'partial_resultset'
883 signals that the search was partial (hit count is lower or equal than
884 real hit count). For Z39.50, the information is stored in resultSetStatus
885 member of SearchResponse APDU. For SRU, the information is signalled
886 via SRU diagnostic 59: "Result set created with valid partial results
889 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
891 --- 2.1.46 2007/01/13
893 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
895 Added ZOOM_connection_peek_event.
897 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
898 the following new functions:
899 ZOOM_event_nonblock, ZOOM_connection_process,
900 ZOOM_connection_get_{socket,mask,timeout},
901 ZOOM_connection_fire_event_{timeout,socket}.
902 The existing blocking event handler, ZOOM_event, is a wrapper for the
903 + blocking ZOOM_event_sys_{poll,select}.
905 Implemented function ccl_xml_config which parses XML version of CCL
906 configuration (bug #798).
908 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
910 Added timings utility (yaz/timing.h)
912 --- 2.1.44 2007/01/03
914 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
917 Fixed bug #779: Rotation of apdu.log fails.
919 Fixed for character set conversions:
920 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
921 Honor G1 set in MARC-8 decoding.
923 --- 2.1.42 2006/12/17
925 Fixed bug #775: char conversion does not handle Alternative UTF-8
928 Implemented function yaz_marc_read_line which parses MARC line format
929 records. There is a wealth of formats out there. So far, this function
930 reads line records produced by yaz_marc_write_line.
932 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
933 more generic and easier to remember(!) options: -i format and -o format
934 which specifies input format and output format respectively - where
935 format is one of "marc", "marcxml", "line", "marcxchange".
937 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
938 does not print anything except warnings for records.
940 For yaz-marcdump, added support for MARC split into files (-s) with a given
943 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
944 spec, at http://www.loc.gov/standards/sru/record-update/
945 This has changed the binary layout of the following structs:
946 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
947 bend_update_rr . Patch by Ko van der Sloot.
949 Added GFS utility function bend_assoc_is_alive which returns 1 if
950 association is still alive (client is connected); 0 otherwise (client
951 closed connection). This allows busy servers to stop working for
954 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
955 been a separate piece of software. This version of ziffy has been modified
956 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
958 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
960 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
961 Client code may now interrogate options such as "init_opt_sort" to
962 find out whether the server claims to support various options.
964 --- 2.1.40 2006/11/27
966 Added utilities yaz_{set,get}_esn to set/get element set name from
969 Removed the build of libyazthread.la. The libyaz.so is the threaded version
970 of YAZ and has been so since YAZ 2.1.10.
972 Implemented ZOOM_record_error which returns error information for
973 record (surrogate diagnostic).
975 --- 2.1.38 2006/10/31
977 Updates for SRU Update by Ko van der Sloot:
978 1. Changed name from "operation" to "action"
979 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
980 versions in the code, marked as 'backward compatible'.
981 3. Added diagnostics for SRU Update.
983 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
985 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
987 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
989 For GFS, fixed problem with SRU diagnostic 'First record position out of
990 range' being issued for 0 hits.
992 zoomtst10 part of Windows Build.
994 --- 2.1.36 2006/10/13
996 Implemented yaz_filepath_comp which splits a path into file path
997 components (required by Zebra 2.0.3+).
999 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1000 BSD inspired license until now so this should not have any real impact on
1001 anybody. See http://www.opensource.org/licenses/bsd-license.php
1003 Fixed bug #687: Missing log lines.
1005 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1008 Fixed bug #689: SRU diagnostics to be added.
1010 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1011 whether a connection is idle (no more work do do).
1013 --- 2.1.34 2006/10/04
1015 Change type of optval from long to int for invocation of setsockopt with
1016 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1018 Added support for specifying the max log file size for the Generic
1019 Frontend Server. The size is given with option -r.
1021 --- 2.1.32 2006/09/21
1023 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1025 --- 2.1.30 2006/09/17
1027 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1030 Fixed bug in Generic Frontend Server that could cause a server to stop
1031 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1033 For the generic frontend server, the maximum record size is used as maximum
1034 size of incoming packages (SRU + Z39.50). The value until was previously
1035 only used in Z39.50 Init negotiation and, later, in a session controlled
1036 sizes of records returned. This is controlled using -k option. It can be
1037 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1039 --- 2.1.28 2006/09/04
1041 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1044 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1046 New option for yaz-marcdump -lpos=value which allows setting a portion
1047 of MARC header to a certain value.
1049 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1051 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1052 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1054 --- 2.1.26 2006/08/15
1056 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1059 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1061 --- 2.1.24 2006/08/08
1063 Fixed MARC ISO2709 encoding routines to deal with character set
1066 Minor changes to GFS logging. Database included in search request log
1069 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1070 cached/multiple records.
1072 Shared libraries are built by default on Unix+configure.
1074 Changed cql2pqf transformation to use a different evaluation order. The
1075 new order is: always, relation, structure, position, truncation, index
1076 and relationModifier. Old order was: always, relation, relationModifier,
1077 structure, index, position, truncation. Note that the the latter ones
1078 override former ones for identical attributes.. The new scheme means that
1079 it is possible to override any existing attribute with a relationModifier.
1080 And also that it is possible to override everything for the index rule
1081 (except the ones listed in relationModifier). No order is perfect but this
1082 one, we believe, covers more real cases.. The "always" should have been
1083 called "default", since the attributes there can be overridden with all
1086 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1087 compilation phase, but also for yaz-config --cflags output. This allows
1088 us to have public headers with Libxml2 stuff in them . It should also,
1089 eventually, make Libxml2 checks redundant in packages using YAZ, such
1092 --- 2.1.22 2006/06/15
1094 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1095 stored in uri, message and details.. Previously diagnostics were stored
1096 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1097 compatibility.. but he's probably the only one affected, so.
1099 Added support for CCL, compiled on the client side, in ZOOM-C. This
1100 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1101 input; the resulting query objects can be used for for searching with
1102 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1104 YAZ' configure searches for OpenSSL by default.
1106 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1107 SL_CTX_use_certificate_file. See
1108 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1109 for more info. Thanks to Ko van der Sloot.
1111 --- 2.1.20 2006/06/02
1113 Bug #600: SRU GET, POST support for yaz-client. Introduced
1114 command 'sru' which selects method SOAP/GET/POST.
1116 Allow missingValueAction to be specified for the sortspec string -
1117 function yaz_sort_spec. By default, the missing value action is null.
1118 Use ! to specify "abort". Use = followed by stringvalue to specify default
1121 Ensured that Present-handler (if defined) is called in GFS before any call to
1122 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1123 searchRetrieve requests.
1125 Documentation for YAZ is now based on the Docbook XML/XSLT using
1126 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1127 is no longer depending on jade/openjade or docbook-to-man scripts.
1128 PDF is no longer part of the distribution - but can optionally be
1129 made using DSSSL/jadetex or FOP.
1131 Added retrieval handling support in Generic Frontend Server to support
1132 conversion between MARC/XML as well as XSLTtransforms. See
1133 etc/yazgfs.xml for an example.
1135 Added Authentication support to Generic Frontend Server in SRU
1136 mode. Authentication using HTTP Basic is supported, as is the use
1137 of 'x-username' and 'x-password' parameters in the request itself.
1139 Added support for a new character set MARC8s identical to MARC8 except
1140 that it converts combined characters to single Unicode characters in the
1141 Latin-1 range (when possible).
1143 --- 2.1.18 2006/04/24
1145 ASN.1 compiler 0.4: generates brief Doxygen file header for
1146 generated .h/.c files.
1148 Utility yaz_iconv now supports conversion to MARC-8.
1150 New facilities for the MARC module. The reading - and writing of
1151 content are separate methods for the yaz_marc_t handle. The following
1152 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1153 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1154 format). Write functions have prefix yaz_marc_write_.. The existing
1155 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1156 available. Removed support for OAI-MARC and simplexml (not the
1157 simplexml from PHP5).
1159 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1160 to be returned for this connection.
1162 --- 2.1.16 2006/03/31
1164 Allow multiple languages and charsets to be specified with
1165 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1166 negcharset iso-8859-1,utf-8
1168 Translation of proximity nodes from CQL into PQF now works.
1170 Moved to automake 1.8, 1.9.
1172 Added function yaz_log_set_handler which allows a log handler to be
1173 installed. This handler will be called for all log messages. Output
1174 to file is also produced; but that can be disabled by passing NULL
1175 fname to yaz_log_init_file.
1177 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1179 For SRW (including GFS), accept application/soap+xml as content-type
1182 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1183 produces NO stylesheet reference even if a default stylesheet is specified
1186 --- 2.1.14 2006/03/14
1188 Updated Windows package to include yazd.dll + yazd.lib for the
1189 Development component.
1191 If the environment variable YAZ_LOG is set, then it is used as a
1192 string indicating the default level of logging to use if not
1193 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1194 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1195 used as before. So, for example, to omit warnings from YAZ logging,
1196 export YAZ_LOG=-warn
1198 cql_transform() now map structure and other attributes before indexes,
1199 so that index-specific structures and other attributes can override
1200 defaults. So now a combination of mapping specifications such as:
1202 index.dc.date = 1=date-modified 4=5
1203 does the right thing.
1205 cql_transform() now also respects the "always" mapping specification,
1206 which establishes an initial set of attributes to be used for all
1207 terms except where overridden by more specific attributes associated
1208 with the index, relation or modifier.
1210 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1211 which mode to use; one of "post", "get" or "soap" (SRW, default).
1213 Fixes for yaz_iconv routines: changed trie-based character set conversions
1214 to use only non-negative values for bit fields due to Sun's C compiler not
1215 supporting negative values.
1217 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1218 sequences where not read correctly. Fix by Rustam Usmanov.
1220 Updated win/makefile to use options, settings which makes things
1221 compile with VS C 2005.
1223 --- 2.1.12 2006/02/01
1225 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1227 In ZOOM socket code, use select instead of poll on MacOSX.
1229 ZOOM-C now support client-side compilation of CQL into RPN that is
1230 sent to the server, enabling CQL to be used against all Z39.50
1231 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1232 ZOOM_query object, and submit it using ZOOM_connection_search().
1233 The CQL-to-RPN translation uses a configuration file, the name of
1234 which must be specified in the Connection's "cqlfile" option.
1236 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1237 function, which takes as its start-term parameter a ZOOM_query object
1238 (which may have had either CQL or RPN set into it).
1241 --- 2.1.10 2005/11/29
1243 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1244 GFS to support this as well. Backend handler, bend_srw_update, does the
1245 update work. Code contributed by Ko van der Sloot.
1247 Allow retrieval of Search Result-1 information in ZOOM by the use of
1248 options that are attached to a result set. ZOOM documentation updated
1251 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1252 UTF-8 conversion. Patch by Raj Patel.
1254 Added option -m to GFS to control formatting of timestamps in log file.
1256 Added 'exit' as synonym for 'quit' in yaz-client
1258 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1259 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1260 for the new members. Patch by Ko van der Sloot.
1262 Added support for SRU POST. It is supported for content-type
1263 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1265 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1266 Instead make the library libyaz.la multi-threaded. Threading as a whole
1267 can still be disabled by configure option --disable-threads. Previosly,
1268 with older GLIBCs there were problems with MT libs under Apache. This
1269 has now been fixed a long time ago.
1271 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1274 CQL module modified to be case insensitive for relations/indexes/operations.
1276 Fixed bug in CQL transform code: incorrect value relationModifieder
1279 Added 'show all' command for yaz-client which retrieves all results
1282 Added new yaz-client, xmles, which takes a (private) OID and
1283 a document to be sent as an extended service request.
1285 Describe new yaz-client commands wait_response and set_auto_wait.
1287 Increase TCP/IP listener backlog from 3 (which I am guessing was
1288 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1289 that the socket will queue as many incoming connections as it's able
1290 to handle ongoing connections. In other words, it will never now
1291 refuse a connection that it would be able to handle merely because
1292 it's not got around to accepting() enough of the pending connections
1293 yet. This is the behaviour anyway under Linux, where the listen()
1294 argument is ignored; but not under BSD and on systems such as
1295 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1296 YAZ-based servers should now be uniform across operating systems in
1299 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1300 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1301 This allows yaz-marcdump to read large MARC batches (>2 GB).
1303 Modified all YAZ source files - except the source which is auto-generated
1304 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1307 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1308 corresponding to the existing *_setl() function. These allow option
1309 values containing arbitrary valuues.
1311 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1312 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1313 except that it returns an indicator of whether or not the sort
1314 criterion was accepted (0 for OK, -1 for invalid).
1316 --- 2.1.8 2005/06/07
1318 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1319 MARC output rather than returning "new" buffer.
1321 yaz-client warns about unknown init options.
1323 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1325 --- 2.1.6 2005/05/24
1327 Added support for SRW sort in Generic Frontend Server. Patch
1328 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1329 sortKeys - or NULL if none is provided.
1331 Fixed bug #307: It was impossible to specify indefinite/no timeout
1332 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1335 Added support for multiple languages and charsets to be specified in
1336 ZOOM. Each charset/language is separated by a blank. If negotiation is
1337 in effect in init-response, Option
1338 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1339 Code based on patch by Vasiliy Osadchuk.
1341 Fixed bug #306: infinite recursion that occurred when calling
1342 yaz_log_level_init as the first call (before other log level or
1345 Fixed bug in scan handling in front end server: if preferred-Position-In-
1346 Response was non-present, a NULL pointer referece was performed.
1348 --- 2.1.4 2005/04/26
1350 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1351 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1352 now defined for all those error codes. So instead of putting 109 in
1353 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1354 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1356 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1359 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1361 Program yaz-client now exits and produces an error message if multiple
1362 Z39.50 servers are specified on the command line (none or one allowed
1365 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1368 --- 2.1.2 2005/03/16
1370 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1372 Fixed bug #272: Preserve spacing for CCL terms.
1374 --- 2.1.0 2005/03/14
1376 Added support for virtual hosts and multiple backend servers for
1377 the YAZ frontend server. The configution is XML based and
1378 support specificition of CQL to RPN mappings and explain information.
1379 See section "Virtual Hosts" in the YAZ manual.
1381 Extended OPAC display utility. OPAC display utility renders
1382 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1383 to supplement yaz_marc_decode_wrbuf.
1385 Fixed a bug in MARC decoder that could caused it to crash for some
1386 invalid MARC records. More diagnostics and warnings where added in
1387 XML output (warnings, etc are stored in comments).
1389 --- 2.0.34 2005/02/08
1391 Fixes for UNIX domain sockets. Bug #261.
1393 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1395 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1396 Added yaz_marc_subfield_str which defines subfield lead string which is
1397 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1398 yaz_marc_endline_str which defines end of fields string used in
1399 YAZ_MARC_LINE format. Default string is newline.
1401 Experimental support for MarcXChange. This format can be produced
1402 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1403 http://www.bs.dk/standards/MarcXchange.xsd
1405 Added yaz-client commands scansize that sets maximum number of
1406 entries to be returned by scan.
1408 --- 2.0.32 2005/01/11
1410 Added support for SRW scan in yaz-client and Generic Frontend Server.
1412 * Added whereInList member to SRW Scan Term.
1414 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1416 Fixed NMEM system to return aligned blocks on the smallest boundaries
1417 that are suitably aligned for all possible types on the particular
1418 architecture YAZ is being built for.
1420 --- 2.0.30 2005/01/04
1422 Fixed numerious warnings that was issued with newer versions of GCC.
1424 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1425 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1428 Make YAZ Generic Frontend Server slightly faster.
1430 Enhance (and reduce) logging for Generic Frontend Server.
1432 Revert YAZ log system so that it flushes every write operation
1433 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1435 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1436 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1437 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1438 will effectively disable old definitions.
1440 --- 2.0.28 2004/11/09
1442 Added yaz_log_time_format which specifies log format using
1445 Added yaz_log_module_level which returns mask for a module. Value
1446 is non-zero mask a if module is enabled; zero if disabled.
1448 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1449 in include/yaz/cql.h.
1451 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1453 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1455 Fixed bug #172: RPM builds does not enable SSL.
1457 Doxyfile.in part of dist. Doxyfile generated by configure.
1459 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1460 are given and the corresponding component does not exist.
1462 Extend CCL documentation in YAZ reference. Describe r=r.
1464 --- 2.0.26 2004/10/01
1466 Fixed MARC->MARCXML conversion to properly deal with
1467 fields, subfields, indicators having non-ASCII characters.
1469 Fixed MARC->MARCXML conversion so that ASCII control characters
1470 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1473 Added YAZ GFS support for conversion from Z39.50 surrogate
1474 diagnostics to SRW surrogate diagnostics.
1476 Bug fix: YAZ GFS did not return schema in explainResponse.
1478 --- 2.0.25 2004/09/30
1480 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1481 now converts recordSchema to elementSetName as well as schema URI.
1483 Fixed bug in COMSTACK that prevented HTTP request packages from being
1486 --- 2.0.24 2004/09/29
1488 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1489 does not require white-space before and after the dash in a range, e.g.
1490 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1493 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1494 due to new GCC removing "redundant" code.
1496 Added yaz-client commands scanpos and scanstep that sets preferred
1497 position and step-size for scan.
1499 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1501 Added CCL utility ccl_qual_buf which parses one or more CCL
1502 spec lines in a buffer.
1504 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1505 of name and value - ignoring empty lines and comments.
1507 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1509 Added odr_get_element_path which returns current element path for an
1510 ODR handle. This utility is useful in error handling or user-defined
1513 Added ODR_PRINT utility odr_set_stream which is is a more generic
1514 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1515 to a write function and pointer to close function. The close function - if
1516 non-NULL - will be called during odr_destroy.
1518 Fixed bug in CCL parser where truncation char was not removed from
1519 right side when truncation=both was in effect.
1521 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1524 --- 2.0.23 2004/08/11
1526 Fix buffer overrun in CQL parser when dealing with proximity (%).
1528 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1529 to UTF-8/UCS conversion is now only based on codetables.xml.
1531 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1533 --- 2.0.22 2004/08/06
1535 Add support for more "commit changes" in ZOOM (uses Extended Services).
1537 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1540 Yet another small fix for configure of SSL.
1542 --- 2.0.21 2004/05/14
1544 Fix SSL libs for configure when --with-openssl=DIR is given.
1546 --- 2.0.20 2004/05/10
1548 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1550 SSL comstack now uses yaz.pem certificate file on server side
1551 by default. Certificate filename can be configured by calling
1552 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1554 Fix bug regarding multiple calls to ZOOM_connection_connect.
1556 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1558 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1559 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1561 ZOOM now allows inspection of X509 peer certificate for verification.
1562 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1564 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1565 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1566 as "modular" but it simplifies things.
1568 Added cs_get_peer_certificate to that returns peer X509 PEM.
1570 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1571 NULL if SSL is unavailable.
1573 Documentation about MARC decoding tools.
1575 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1577 --- 2.0.19 2004/03/30
1579 Rename CHANGELOG to NEWS to follow GNU style packing.
1581 Fix bug with missing initialization of member in init_diagnostics.
1582 This bug affects threaded version of GFS server.
1584 --- 2.0.18 2004/03/20
1586 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1589 Ensure zlib.dll is packed with Windows install.
1591 --- 2.0.17 2004/03/17
1593 Fix encoding of xsd:string to use text instead of CDATA.
1595 Fix endless loop in CQL parser with unbalanced ".
1597 Use a more compact way to store MARC-8 conversion tables.
1599 --- 2.0.16 2004/03/16 Debian only
1601 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1604 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1609 --- 2.0.15 2004/03/01
1611 Another fix for decoding of XML packed records.
1613 --- 2.0.14 2004/02/25
1615 Fixes for Chunked encoding. White space not ignored after length spec.
1617 Update NS and use default NS for SRW diagnostic elements.
1619 --- 2.0.13 2004/02/23
1621 Implement ZOOM_resultset_cache_reset which resets record cache.
1623 Implement ZOOM_resultset_sort which sorts a result set.
1625 Implement chunked HTTP transfer.
1627 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1629 --- 2.0.12 2004/02/16
1631 Added member 'schema' to bend_explain_rr structure so that backend
1632 can specify explain record identifier. Defaults to Zeerex 2.0.
1634 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1636 --- 2.0.11 2004/02/16
1638 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1641 Added init command for yaz-client which sends "extra" init request.
1643 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1644 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1646 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1648 Make ZOOM error code for "invalid query".
1650 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1652 --- 2.0.10 2004/02/05
1654 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1657 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1659 Added option -p <file> to make Generic Frontend Server to write PID file.
1661 Added option -D to put Generic Frontend Server in background on its own.
1663 Make ZOOM C recognize option "password". If unset, "pass" is used
1664 (for backwards compatibility).
1666 Fixed a bug in Generic Frontend Server that could make it crash if a
1667 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1670 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1671 Must be issued before open, in order to be in effect.
1673 --- 2.0.9-6 2004/01/12 Debian/Windows
1675 Make the SRU server more picky WRT unknown params, etc.
1677 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1679 New YAZ client command, options, that sets Z39.50 options.
1681 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1682 options from a string of tokens (one token for each option bit).
1684 Update SRW diagnostic code messages.
1686 --- 2.0.9-5 2004/01/07 Debian/Windows
1688 Handle user defined stylesheet for SRW/SRU.
1690 --- 2.0.9-4 2004/01/06 Debian/Windows
1692 Fix bug in decoding of Content-Length.
1694 --- 2.0.9-3 2004/01/06 Debian/Windows
1696 Fix a bug with decoding of XML packed records.
1698 --- 2.0.9-2 2004/01/05 Debian only
1700 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1702 Fix bug in SRW/SRU diagnostics decoding.
1704 --- 2.0.9 2004/01/05
1706 Fixed bug in Generic Frontend Server which could drop records exceeding
1707 preferred message size. Reported and fixed by Irina Dijour.
1709 Fixed calculation of package size for structured records in Generic
1710 Frontend Server. Reported and fixed by Irina Dijour.
1712 Fixed namespace for SRW/SRU diagnostics.
1714 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1716 --- 2.0.8 2003/12/22
1718 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1719 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1722 CQL changes to reflect recent changes to the specification:
1723 * Documentation talks about context sets instead of index sets.
1724 * Documentation talks about indexes instead of qualifiers.
1725 * The CQL-to-PQF transformer's configuration file now uses
1726 "index.set.name = <attributes>" instead of the old form
1727 "qualifier.set.name = <attributes>". (Both forms are still
1728 understood but the latter is deprecated.)
1729 * CQL terms with no explicit index specified are now interpreted as
1730 cql.serverChoice instead of srw.serverChoice (which of course
1731 behaves exactly the same.)
1733 --- 2.0.7 2003/12/16
1735 MARC conversion can now generate ISO2709 output in another
1736 character set. yaz-marcdump uses this facility if you invoke it
1739 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1740 functions from there can be used from C++.
1742 --- 2.0.6 2003/12/04
1744 Frontend server now transfers memory from decoded packages to stream
1747 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1748 references to show up.
1750 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1751 the ZOOM Abstract API. The older names for the same options are still
1752 also supported for the benefit of old applications.
1754 ZOOM-C supports "implementationId" and "implementationVersion" options
1755 to go along with "implementationName". These allow the user code to
1756 specify identification strings to be sent to servers.
1757 Add OID for the new ExtLite attribute set.
1759 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1760 as requested/supplid by Ere Maijala <ere@atp.fi>
1762 For generic frontend server, reverse the order of
1763 "toolkit-supplied / application-supplied" strings sent as implementationId,
1764 Name and Version. Also, remove the spaces around the slash. This brings
1765 the GFS in line with the behaviour of ZOOM-C on the client side.
1767 Add function ZOOM_scanset_display_term.
1769 yaz-client shows scan displayTerm if present.
1771 Utility yaz-iconv is now installed by default along with the man page
1774 Extend configure check for OpenSSL to use pkg-config where available (such
1777 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1778 server to specify uid/gid/mask for socket using the format
1779 unix:[user=uid,][group=gid,][umask=mask,]file=path
1780 If file= is omitted the existing format is assumed, e.g.
1782 in which case the mask is 0666 (rw for everybody).
1784 Major restructure of YAZ source. All source in libyaz is in src directory.
1785 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1786 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1788 Added man page for utility yaz-marcdump (used to be called marcdump).
1789 yaz-marcdump is installed by 'make install'.
1791 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1792 of incoming package failed.
1794 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1796 Change prototype of odr_perror: add const to message string.
1798 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1800 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1801 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1802 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1803 DNS lookup. There should not be any compatibility problems with this
1804 assuming that blocking=1 or 0 is used.
1806 Fix bad reference in UNIX comstack in function cs_addrstr.
1808 Fix for compilation on AIX.
1810 The generic front-end server (server/seshigh.c) now supports returning
1811 Init diagnostics to the client in User-information-field, in
1812 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1815 --- 2.0.4 2003/09/04
1817 Allow any CQL relation (not just all,any,exact,scr).
1819 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1820 that features the same UI.
1822 Implemented command update0 in YAZ client which is equivalent to
1823 update but uses old of Ext Update ASN.1.
1825 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1826 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1827 Previously no OID was used for this info.
1829 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1830 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1831 returns 'malformed search term' otherwise.
1833 SortResponse member resultCount now set to NULL in sort handler of
1836 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1839 Add three new utility functions for translating OIDs between various
1840 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1841 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1842 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1843 char *oid_to_dotstring(const int *oid, char *oidbuf);
1844 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1846 Reverted modifications for ES Update definition for z_IU0Update
1847 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1848 is back to YAZ 2.0.2.
1850 String value attributes for CCL parser.
1852 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1853 which their FirstSearch server returns in Init responses, sometimes
1854 carrying useful diagnostic information when Init fails. This has the
1855 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1856 "z39.50/oclcui.asn", where its definition is somewhat different from
1857 what OCLC document on their web-site, as required to interoperate with
1860 Support for anonymous authentication in yaz-client. Use the command
1863 * Fix the OID of the Index Data-local "admin" Extended Service from
1864 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1865 the 1000, which indicates a locally-defined OID, was a mistake.
1867 --- 2.0.3 2003/06/20
1869 Fix CCL directive @case handling so that it affects string match for
1870 both CCL keywords and qualifiers.
1872 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1873 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1874 Decoder has been updated with ASN.1 changes as listed in
1875 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1876 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1877 z_IUUpdate, remains unchanged.
1879 ZOOM_record_get may now return a record in a specific character set.
1880 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1881 "from" is the character set of record as returned by target. "to" is
1882 the character set to be returned. If omitted, "to" is UTF-8.
1884 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1886 New ODR utility, odr_getelement, which returns name of element for
1887 which encoding/decoding failed.
1889 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1890 in cases where a required element was omitted.
1892 Bug fix: some MARC8 sequences were not converted.
1894 New ZOOM option "step" which specifies number of records to be
1895 retrieved in one chunk. Used in conjunction with "start" and "count".
1897 SRW support for yaz-client. Use scheme http: to use it, e.g.
1900 yaz-client no longer does (un)intelligent character set conversions
1901 by default. Can be enabled with charset and marc_charset commands.
1903 xmalloc trace fix for 64-bit systems such as DEC alpha.
1905 Solaris 2.6 compile fix.
1907 New function, cql_strerror() translates SRW error codes, as returned
1908 by cql_transform_error(), into human-readable English strings. Used
1909 in yaz-client diagnostics when appropriate.
1911 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1912 converts it into a type-1 query which is sent to the server. This
1913 makes CQL available for use with all Z-servers, as opposed to the tiny
1914 minority that can handle CQL queries themselves.
1916 --- 2.0.2 2003/04/28
1918 New Debian package layout similar to the Redhat Package layout.
1920 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1921 and search result respectively.
1923 --- 2.0.1 2003/04/25
1925 Redhat package is now several packages: libyaz (runtime libraries),
1926 libyaz-devel (development and documentation, and yaz (utility programs).
1927 Package spec file by Morten Bogeskov.
1929 New member 'schema' in struct bend_fetch_rr which the name of requested
1930 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1931 handler MAY set this to reflect the schema of the returned record.
1933 New member 'display_term' in struct scan_entry. GFS now sets member entries
1934 and allocates scan entries to be filled by user scan handler. In previous
1935 version, entries member was allocated by the scan handler. That still works,
1936 but the GFS will ignore member display_term - assuming it was NOT set by
1937 the handler. The fact that the GFS now allocates the entries both allows
1938 for new members and makes a scan handler easier to write.
1940 Fix CQL lex buffer overflow.
1942 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1943 SRU default recordPacking is string.
1945 SRU protocol support for frontend server.
1947 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1949 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1951 Added scan for the ZOOM shell (zoomsh).
1955 * String Identifers for Schemas (Amendment 5).
1956 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1957 Old definition for schema
1958 Odr_oid *schema; /* OPT */
1963 Z_InternationalString *uri;
1964 #define Z_Schema_oid 1
1965 #define Z_Schema_uri 2
1968 * resultCount parameter to Sort Response (Amendment 1).
1969 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1971 Support for SRW 1.0 over HTTP. This is an optional feature and
1972 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1975 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1976 on the same port. SRW SearchRetrieveRequests are mapped
1977 to bend_init,bend_search,bend_fetch,bend_close.
1979 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1981 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1982 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1984 ZOOM connections are SRW based if schem http is used for hostname
1985 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1986 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1988 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1989 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1990 distance=n, order=true/false, relation=le, prox unit=word. If
1991 n is omitted, distance 1 is used.
1993 Fixed problem with C compiler include path in wrong order.
1995 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1996 on Solaris. Patch from Ko van der Sloot.
1998 New MARC decode API. All new functions operate on a yaz_marc_t
1999 handle. The most important new functions are: yaz_marc_create,
2000 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2001 decode and destroy respectively. Decoder can produce formats
2002 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2003 include/yaz/marcdisp.h.
2005 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2006 to UTF-8, UCS-32, wchar_t or Latin-1.
2008 * Prototypes for yaz_iconv_-functions moved to separate header
2009 include/yaz/yaz-iconv.h.
2011 Make a few private functions 'static' in unix.c. This prevents
2012 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2014 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2015 are set when Init Response is received.
2017 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2018 but returns diagnostic set as well.
2020 New function yaz_strerror which is a portable wrapper for
2021 strerror/strerror_r/GetLastMessage.
2023 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2024 is returned for MARC. If type is "oai", then OAI MARC is returned.
2026 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2029 --- 1.9.2 2002/11/26
2031 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2033 Fix bad race conditions on SIGTERM and terminate gracefully in
2036 Move retrieval (data1) module to Zebra since nobody seems to be
2039 Add GRS-1 render for ZOOM using same format as yaz-client.
2041 --- 1.9.1 2002/10/05
2043 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2045 Fix broken ESpec handling in data1 module.
2047 SGML reader parses comments and makes them part of the data1 tree.
2049 Added several type casts so that YAZ compiles as C++ code.
2051 ZOOM didn't handle PDU encoding failures properly.
2053 Added more Bib-1 diagnostics (approved extensions).
2055 GNU configure: better check for iconv.
2057 More portable use of accept, getpeername. Check for socklen_t. Use
2058 int/size_t if socklen_t is not defined.
2062 PQF parser rejects bad queries - including those with extra
2063 characters in them. PQF parser used to silently ignore that.
2064 Cleaner API for PQF added, which allows you to get detailed
2065 error information for bad queries (see yaz/pquery.h).
2067 Fixed bug in ZOOM_record_get for type "database".
2069 Implemented mini iconv library supporting conversions between
2070 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2072 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2074 --- 1.8.9 2002/08/20
2076 Fixed ZOOM C record cache so that preferredRecordSyntax and
2077 elementSetName is used to check for already fetched records.
2079 --- 1.8.8 2002/08/02
2081 Added three members in bend_initrequest structure to facilitate
2082 character set negotiation.
2084 Fixed a bug in frontend server that could cause indefinite
2085 loops under rare conditions.
2087 Revised character set utilities (charneg.h) so that encoding
2088 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2090 For PQF, directive @term <type> sets term type for Scan/Search.
2091 Here <type> is general, string, numeric, null. The term type
2092 is inherited - just like @attr.
2094 New call odr_set_charset that sets character set conversion for
2095 international-strings on a ODR stream. Prototype is:
2096 int odr_set_charset(ODR o, const char *to, const char *from);
2097 The InternationalString is still represented as C string in YAZ
2098 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2099 won't). On the protocol level, you can use any encoding.
2101 Support for UNIX sockets in ZOOM.
2103 Solaris recv sometimes returns errno == ENOENT. It is treated as
2104 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2106 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2107 both client and server. Code by Morten Bogeskov.
2109 --- 1.8.7 2002/05/22
2111 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2112 that they can be used directly from Visual Basic. You must recompile
2113 your windows APP if you're using ZOOM.
2115 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2116 Commands "lang" and "charset" sets language and character set respectively.
2117 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2118 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2120 Attributes from multiple CCL fields may be OR'ed rather than merged
2121 using directive "@field or". Fields are still merged by default -
2122 equivalent to "@field merge".
2124 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2127 Fixed bug in zget for parameter ExtendedServicesResponse.
2131 --- 1.8.6 2002/03/25
2133 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2135 Client displays USR.1:SearchResult-1 (hits per term).
2137 Additional Search Info for search in Generic Frontend Server.
2139 Fixed CCL parsing of "field=s".
2141 WIN32 installer - using the excellent NSIS software from nullsoft.
2143 Fixed CCL parsing of "field = - <number>".
2145 Added function yaz_marc_decode that decodes MARC for line mode
2146 display or XML (similar to that used by JZKit).
2148 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2149 Z39.50. But ISO/ILL was, however.
2151 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2152 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2154 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2155 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2157 --- 1.8.5 2002/02/03
2159 New YAZ client features: Command completion and new commands:
2160 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2161 Code provided by Jacob Poulsen.
2163 New call oid_trav, that visits all registered OIDs via callback.
2165 Function ZOOM_record_get now returns const char pointer rather than
2166 void pointer. It saves a lot of type casts.
2168 For YAZ client, command "auth" now allows you to set authentication
2169 in IdPass style. It is enabled when three tokens are given - order
2170 is user, group and password.
2172 Fix memory leaks in MARC record handling for ZOOM.
2174 New option for YAZ client, -k <kilobytes> that sets
2175 maximum record size. Similar to -k option for generic frontend
2176 server and yaz-ztest.
2178 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2180 Prefix query parser reports "fail" when bad attribute set is given.
2182 Fix in MARC decoder. Proximity logging. Fix for attribute set
2183 in scan handler for server. Patches by Shigeru Ishida.
2185 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2188 Configure option --with-openssl=<dir> now works when a directory is
2189 specified. Patch provided by Morten Bogeskov.
2191 New option for YAZ client, -u <auth>, that sets authentication.
2193 ZOOM fix: error information was sometimes "missing", since error
2194 was cleared/reset too when it shouldn't.
2196 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2198 --- 1.8.4 2002/01/04
2200 Scan for ZOOM API. New object ZOOM_scanset. New functions
2201 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2202 ZOOM_scanset_destroy.
2204 New ZOOM function, ZOOM_connection_last_event, that returns type
2205 of last event (such as "receive data", "send data", "apdu received",
2208 New ZOOM option, schema, that specifies schema for retrieval.
2210 New CCL feature. Qualifiers can be aliases for one or more
2211 other qualifiers (if more than one is given, OR is used).
2213 ZOOM uses named result sets if target supports it.
2215 Two new YAZ client commands: . (dot, which sources a script of YAZ
2216 client commands), and ! (to execute shell command.). Implemented
2219 Working on Debian packages.
2221 --- 1.8.3 2001/11/19
2223 YAZ client enables named result sets only if target supports it.
2225 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2227 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2228 with key="host" to get same result.
2230 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2231 Function Z3950_resultset_record(s) returns references to records
2232 "owned" by resultset. To become owner use Z3950_record_clone.
2234 Function z_ext_record handles Extended Services. Thanks to
2237 --- 1.8.2 2001/11/12
2239 CCL Parser fix: ignore token comma when dealing with and-lists.
2241 Documentation updates for COMSTACK.
2243 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2244 Changed prototype Z3950_records. For some functions, int parameters
2245 were changed to size_t.
2247 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2250 New MARC decode/display function, marc_display_exl, which properly rejects
2251 non-ISO2709 records. YAZ client uses it.
2253 --- 1.8.1 2001/10/29
2255 Fix bug: local attribute set wasn't set correctly in PQF strings.
2259 * Old Z39.50 codecs no longer supported.
2261 Added ZOOM C binding. See http://zoom.z3950.org/
2263 Renamed states for COMSTACKs to avoid confusion with events.
2265 Implemented cs_look and proper cs_rcvconnect.
2267 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2269 Configure detects POSIX threads on OpenBSD.
2271 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2272 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2274 When error is returned from present handler, non-surrogate diagnostic
2275 is returned in present response (and fetch handler is no longer called).
2277 * Minor adjustments to pquery parser (PQF). Token characters may be
2278 escaped by using backslash (C-style).
2280 PQF parser allows string attribute values to be specified. For @attr,
2281 non-numeric characters after the equal-sign are treated as strings
2282 (e.g. @attr 9=title).
2284 CCL trunction character may be defined (@truncation in file)
2286 * function zget_ExtendedServicesRequest sets waitAction to
2287 waitIfPossible (was wait).
2289 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2292 CCL operator names may be set in field definition files (CCL_bibset).
2293 See ccl/bib1 for an example.
2295 Fixes in ASN.1 compiler for C++ compatibility.
2297 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2298 and "op_or" to avoid conflict with C++.
2300 Fixed problem with GNU readline detection on Redhat 7.0.
2302 Added step-size for Scan backend handler.
2304 Fixed bug that made the frontend server crash when no attribute
2305 set was specified for scan.
2307 Front-end server automatically switches to original working directory
2308 when installed as an NT service. Previously -w had to be specified to
2311 Added extended attributes for retrieval module (data1), so that data1
2312 records carry d1_readXML/SGML attributes. d1_read also supports
2313 null-data rules ( <tag/>)
2315 On UNIX when POSIX threads are available, a separate library libyazthread
2316 is created. Programmers should link with that library and the yaz library
2317 when using threads. The reason for the split was that some applications
2318 on Linux, such as Apache, doesn't work well when using shared objects that
2321 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2322 (or any frontend server) in SSL mode by specifying ssl: followed by
2323 address. Only tested on UNIX.
2325 Added feature for CCL module. Virtual structure s=al or s=ol generates
2326 and-list and or-list respectively instead of phrase search.
2330 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2331 log_mask_str. This was done to avoid name conflicts with other libraries
2332 (such as other PHP extensions).
2334 Added raw OID member for preferred record syntax (request_format_raw)
2335 and returned record syntax (output_format_raw) for backend fetch method.
2337 Config file yaz-config now accepts options so that it returns specific
2338 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2340 Shared library support for UNIX using GNU libtool.
2342 * Modified backend interface. Request/Response struct's replaced by
2343 one read/write C struct. For example bend_fetchrequest and
2344 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2345 Every handler - even search has to be registered in bend_init
2346 handler. This means that the YAZ library no longer refers to
2347 external functions and it makes it possible to make the whole
2348 thing a single DLL/SO.
2350 Added Segment handler for backend server.
2352 Added Zmbol/Zebra administrative functions to YAZ client.
2354 Threaded frontend server on UNIX (when POSIX Threads are available).
2355 Starting the server with option -T enables multi-threading.
2359 Added configure option --enable-comp/disable-comp to control use
2360 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2361 located in sub directory asn.
2363 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2364 in ${exec_prefix}/bin along with the other programs yaz-client and
2367 GNU automake used to maintain makefiles.
2369 Added several OID's.
2371 Changed retrieval module so that we can load records with no abstract
2372 syntax defined. Tagpaths in these records are fully composed of string
2375 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2379 On UNIX, the generated makefile now supports a proper 'make install'.
2380 The prefix can be set via GNU configure to set the install location
2381 (default is /usr/local).
2383 * YAZ programs client and ztest were renamed to yaz-client and
2384 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2385 locations, such as /usr/bin,/usr/local/bin,etc.
2387 * YAZ Header files were moved from include to include/yaz. YAZ Header
2388 files are referred to as include <yaz/log.h> rather than <log.h>.
2389 The YAZ include path (-I ..) is therefore the same as before. Programmers
2390 should update their #include statements or use -Ipath/include/yaz
2391 instead. The main motivation for doing this change is that YAZ header files
2392 can be installed in "standard" locations /usr/include,/usr/local/include
2393 without introducing conflicts, since ALL YAZ header files are stored
2394 in subdirectory yaz (under /usr/include for example).
2396 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2397 rather than project/workspace files. We switched because project files
2398 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2401 Changed name of logging function, logf, to yaz_log, to prevent name
2402 clash with some math-log functions. The YAZ header log.h defines logf
2403 to yaz_log (#define) so there should be no incompatibilities by this
2406 Added bend_start/bend_stop handlers for server. These handler are
2407 called on start/stop of server. For windows they are called whenever
2408 a service is started/stopped.
2410 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2411 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2412 in util/yc.tcl. The auto-generated C code structures are, in a few
2413 cases, incompatible with the old decoders. There are differences in the
2414 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2415 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2416 The preprocessor variable ASN_COMPILED is defined when the compiled
2417 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2418 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2419 wish to use the old encoders/decoders you can specify --disable-yc
2422 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2423 version so that it supports both new - and old version of DB Update
2425 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2426 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2427 change. The name parameter can be set to 0 in which no name is specified
2428 for the construction. The macros odr_implicit and odr_explicit sets name
2429 parameter to zero for the construction involved. New macros
2430 odr_implicit_tag and odr_explicit_tag are similar to the others,
2431 except that a name parameter is added. For programmers' that don't use
2432 ODR they probably only need to change the call to z_APDU and z_External.
2434 Added access control facility by interfacing the TCP wrapper library.
2435 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2436 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2437 name of the daemon and enables the access control as specified in
2438 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2440 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2441 den Dool <H.M.vdnDool@kub.nl>.
2443 Added reference ID parameter to most functions in server API - refer
2444 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2446 Changed name of ccl library to libccl.a (was ccl.a).
2448 Fixed bug in decoder for Explain (Category TargetInfo).
2450 Added support for GNU readline in client. Thanks to Jacob Poulsen
2451 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2453 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2454 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2455 IMPLEMENTATION! This change was made to the development version before
2456 the ZIG decided to retract the amendment. If any users MUST be
2457 compatible with the original Update definition, PLEASE CONTACT US, and
2458 we will include a separate definition corresponding to the old Update
2459 ES. Note that because of the change to the ASN.1 of the
2460 TaskPackageRecordStructure we cannot define a single structure that
2461 will support both versions.
2463 * Added const modifier to buffer parameter for some ODR/BER encoding
2464 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2465 completeWAIS, odr_dumpBER.
2467 Fixed bug in client.c which caused a crash when a scanResponse didn't
2468 contain positionOfTerm.
2470 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2471 * will cause an error in a client if a non-YAZ target sends both a
2472 * list of Scan entries and non-surrogate diagnostics.
2474 Retrieval module enhancements. Tag sets may be typed in the reference
2475 to it. From the .abs-file the "tagset" directive takes a third optional
2476 integer type for the tag set referenced. From a .tag-file the "include"
2477 directive takes a third optional type as well. The old "type" directive
2478 in the tag set itself is still recognized but acts as the default type
2481 Backend interface change. Individual Scan terms returned from bend_scan
2482 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2483 in include/backend.h.
2485 Retrieval module enhancements. Multiple tag sets and attribute sets may
2486 be specified in abstract syntax specs. Revised the error/warning for
2487 logging messages reported by the retrieval module when reading the
2490 Object Identifier system (oid_..) changed. The API is backwards
2491 compatible but the oid-routines now allocates new OID's when needed.
2492 Raw OID's may be specified in oid_getvalbyname.
2494 YAZ now uses GNU configure to generate Makefile(s).
2496 * Minor changes in some of the member names of DeleteResultSetRequest and
2497 DeleteResultSetResponse. See include/proto.h.
2499 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2500 and added member 'languages' in TargetInfo (which was missing).
2502 Changed the way attribute sets are handled in the retrieval
2503 module. These are now cached, just like the abstract syntaxes
2506 Changed YAZ so that it links with compiled ASN.1.
2508 Added Explain-schema definitions and mapping routines. The following
2509 Explain categories have been implemented: AttributeDetails,
2510 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2512 Fixed minor bug in Windows version of Server Library.
2514 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2516 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2518 Added EXTERNAL: UNIverse Resource Report (non-standard).
2520 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2521 ENUMERATED and SET OF.
2523 * Added 'const' to some of the char pointer arguments for the
2524 functions, data1_read_node, data1_getelementbytagname,
2525 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2528 Fixed bug in data1_insert_taggeddata - the last_child member of
2529 parent wasn't initialised.
2531 * Changed data1_read_record and data1_read_node so that the supplied
2532 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2533 doesn't refer to any parts of the "SGML"-buffer.
2535 Fixed bug in server library (Windows version of statserv_remove).
2537 * Changed code so that it compiles as C++. The type definition
2538 of Odr_fun which is a member of Odr_arm was changed. The result is,
2539 that an explicit typecast is needed for the fun pointer when
2540 using Odr_arm - as in:
2541 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2543 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2545 Implemented the new structured date and time definition as approved
2546 by the ZIG. Added schemaId element to the specificTag in Espec-1
2547 (also approved at the last ZIG). Thanks to RVDM.
2549 Added some Object identifiers (RVDM).
2551 Changed the Update Extended Service (RVDM).
2553 Added command "refid" to client which specifies referenceId for
2554 the following requests.
2556 Implemented extended service handling for server. See ztest.c
2557 for an example as well as backend.h. New handlers are registerd
2558 in the Init handler.
2560 * Changed interface for sort in server.
2562 Added new members to statserv_options_block. It allows a server
2563 to read options from another source than just the command line. Thanks
2564 to Charles Woodfield.
2566 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2567 renamed to zboolean. Some C++ compilers complained about the name.
2569 Minor changes to gils.abs. Added index 's' (sort) on title
2570 and date/time-last-modified.
2572 --- 1.4pl2 1998/1/30
2574 Fixed bug in server library regarding inetd mode (-i). This bug
2575 was introduced by release 1.4.
2577 --- 1.4pl1 1998/1/29
2579 Added sort facility in client and backend server interface.
2581 Fixed problem with dependencies in Makefile(s).
2583 Fixed bugs for encoders/decoders of extended services and
2586 Implemented sub-tree feature for schemas. Sub-trees are
2587 referenced in *.abs-files. See explain.abs for an example
2588 of the use of this feature.
2590 Modified bib1.att; local attributes for ANY didn't include
2591 ANY itself (only affects use of the retrieval module).
2593 Fixed bug in plain SGML reader in function data1_read_node:
2594 tags with prefix "var" was incorrectly interpreted as variants.
2596 Added feature "sub-schemas" to enable references to - and definitions
2597 of - group of elements.
2599 * Removed member parent from type data1_element (in data1.h).
2601 Implemented function odr_nullval() that returns the value of
2604 * Removed member num_children from data1_node (in data1.h).
2606 Made NT service interface part of the server library. The
2607 function statserv_main uses the NT service when required and
2608 calls the statserv_start / statserv_close routines.
2610 Routine zget_SearchRequest and zget_PresentRequest fills
2611 resultSetName/Id member with "default" instead of "Default".
2613 Fixed memory leak in server. Request queue member wasn't freed.
2615 Fixed nmem_exit so that memory is freed.
2619 Revised the CCL parser utility to be thread safe.
2621 Added function, oid_ent_to_oid, to replace the function
2622 oid_getoidbyent, which is not thread safe.
2624 * Added nmem_init and nmem_exit to initialize and release
2625 NMEM resources. Function nmem_init should be called once in the
2626 initial thread before NMEM/ODR is used. statserv.c and client.c
2627 have been changed accordingly. The change was necessary to make
2628 NMEM thread safe. The NMEM memory pool is shared amongst threads
2629 in a process. Unix-based applications will still work fine without
2632 Added NT Services interface for the the Z39.50 (statserv) Server.
2633 Refer to the ztest.c source on the usage.
2635 Windows 95/NT port using MSVC5.0. Project files are included in the
2638 * Defined new 'global' handle for the retrieval (data1) system. The
2639 new handled, data1_handle, describes the state of the data1 system.
2640 This handle is passed as first argument to virtually all
2641 data1 related routines. The functions data1_create and data1_destroy
2642 creates and destroys a data1 handle respectively.
2644 Added ODR encode stream member to all backend request structures
2645 init, search, scan etc. This stream should be used to allocate all
2646 memory used for the response when thread safe operation is needed.
2648 Changed the comstack utility, cs_addstr, to be thread safe. The
2649 returned hostname string returned by the function is now part the
2652 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2653 function. The cs_straddr takes a COMSTACK handle as argument, so this
2654 function must be used after cs_create and before bind/connect.
2655 This function is thread safe.
2657 Moved test server to 'ztest' directory - generic server code still
2658 in 'server' directory.
2660 Made prefix query (pquery.c) utility thread safe.
2662 Added new function modifier YAZ_EXPORT to 'export' public DLL
2663 functions when using windows (see include/yconfig.h).
2665 Added definitions to the OID database (util/oid.c) (RVDM).
2667 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2669 Added call to ccl_rpn_delete in client program.
2671 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2672 release of RPN structure.
2674 Added support for C++, headers uses extern "C" for public definitions.
2675 With input from RVDM.
2677 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2678 Thanks to Ronald van der Meer (RVDM).
2680 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2682 Added support for private extensions to the OID database
2683 (oid_setprivateoids()). Thanks to RVDM.
2685 Added optional, physical ANY (key replication)
2687 Fixed null-reference problem in GRS-1 output filter.
2689 Proximity operator added to Prefix Query Format (PQF).
2691 In test client command "base" accepts multiple databases.
2693 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2697 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2699 Smallish bug-fixes in the new encoders/decoders (explain).
2701 Bug fixed in DeleteRequest.
2703 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2705 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2707 Added SOIF syntax (using private OID for now) to retrieval module and client.
2709 Added Update extended service.
2711 Added SearchResult-1 additional info structure.
2713 Added optional CCL (ISO8777) interpreter as separate module. Available
2716 --- 1.2 1996/6/10 (1st anniversary release)
2718 Added Summary record syntax. Lightly tested.
2720 Added OPAC record syntax. Untested.
2722 Added ResourceReport service encoders/decoders. Untested.
2724 Fixed bug in z_Unit - wrong tagging on unitSystem.
2726 Fixed bug in the DiagRecs decoder.
2728 Added options for max PDU size and session timeout to frontend-server.
2730 Added documentation of query-language parsers and other supporting utilities.
2732 [frontend-server] Added Attribute set to the bend_scanrequest API.
2734 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2735 surrogate diagnostics were generated.
2737 [retrieval] Allow multiple local values for attribute.
2739 [retrieval] Allow multiple attributes per element in .abs files. index type.
2741 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2743 --- 1.1pl2 1996/4/10
2745 Minor changes, mostly specific to Zebra's requirements (retrieval)
2749 Repaired bug in frontend server when running multiple listening
2750 endpoints in dynamic mode.
2752 z_External() now won't break if a known, ASN.1 value comes encapsulated
2753 in an octet-string. The value will pass through unmodified in an Odr_oct.
2755 Added a bit of code to the demo client to decode & display
2756 ASN.1-structured records represented in the octet-aligned branch of
2757 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2759 Added z_ext_getentbyref() to the ASN module. Doc updated.
2761 * Completed the SCAN definition in the ASN module. This may break SCAN
2762 code based on older YAZ-versions at compile-time. The fix is easy -
2765 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2766 under the SCAN definition. Remember to initialize this, server-people.
2768 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2769 that this does not extend to ODR and ASN.
2771 Comstack allows insertion of established socket (primarily for
2772 inetd-operation of servers). Doc updated.
2774 Front-end server can now start from the inetd in TCP mode. Doc
2777 --- 1.0pl4 1996/1/24
2781 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2782 the rank and record number.
2784 Adjustments to the frontend server.
2786 Fixed diagnostic BER dumper. It ignored the file argument.
2790 Various changes to retrieval module.
2792 Changed the union discriminators of the protocol files from enums to
2793 ints paired with #defines.
2795 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2798 *Changed operator in the RPN structure to 'roperator', again to avoid a
2801 Fixed problems in Explain decoders/encoders.
2803 --- 1.0pl2 1995/12/6
2805 Memory bug in log module fixed.
2807 --- 1.0pl1 1995/12/5
2809 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2811 Bug in Explain DatabaseInfo module fixed.
2813 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2817 The shift to v1.0 signals that we now consider the *core* functionality
2818 of YAZ reasonably stable (the core being more or less equivalent to
2819 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2820 tested (Explain not at all - though that will happen soonish).
2822 Minor changes to code to support Windows port.
2824 Various minor changes after we're getting to use GRS-1 & co. more.
2826 Added Espec-1 format.
2828 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2829 of the protocol and it cannot be selected when encoding (maps into 'string'
2830 when decoding). Needed to talk to some servers.
2832 Demo client can request simple element set names.
2834 Added Diagnostic Format encoders/decoders.
2836 Added simple Close handling to frontend server (no hooks for resource
2837 reporting yet), and demonstration client.
2839 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2841 --- 1.0b3 1995/08/24
2843 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2844 handled incorrectly when records were requested in the searchResponse. This
2845 will only affect you if you use the frontend-server.
2847 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2848 Test-client will ask for and print GRS1. Ztest will return dummy records
2851 Added Explain encoders/decoders to the service-level API. Untested.
2853 Added Extended Services: Item Order encoders and decoders to the Service-
2854 level API. Untested. We could use a recent copy of the pertinent bits
2855 of the ILL protocol to add those bits.
2857 Added diagnostic format 1 encoders/decoders to the service-level API.
2860 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2861 odr_cons.c, which causes a more correct output.
2863 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2864 was always set to 0 when no records were requested in the searchRequest.
2866 * Added better external-handling. This shouldn't harm old code that
2867 *encodes* externals. It can break code that looks for a
2868 'single-ASN1-type' representation, since those types that are known
2869 are now decoded immediately. Look at the SUTRS sample code in
2870 seshigh.c and client.c. Documentation updated.
2872 Handling of structured records in bend_fetchresponse. Length -1 marks
2873 structured record, type is deduced from format field.
2875 --- 1.0b2 1995/06/27
2876 Fairly quick maintenance release to add SUTRS support.
2878 Fixed handling of SUTRS records in the demonstration client.
2880 * Added format field to the bend_fetchrequest and bend_fetchresponce
2881 structures of the backend API (frontend server). When the record is
2882 returned, the value of the format field is mapped to an OID. The
2883 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2884 of the record. The special value VAL_NONE in the bend_request means
2885 that no specific format was requested by the client. Documentation
2886 updated accordingly. Test server (ztest) will return a fixed dummy
2887 SUTRS record if your client requests SUTRS.
2889 Documentation updated accordingly.
2891 You can now set external libraries and RANLIB support in the top-level
2895 First public release.
