3 SRU: add methods for handling DADS SRU-proxy facets.
5 Separate OPAC record character set for ZOOM_record. yaz_record_render
6 allows a character set given as charset=from/opacfrom,to where 'from' is
7 the character set of a bibliographic record, 'opacfrom' is character set
8 of OPAC record and 'to' is the target character set.
12 yaz-client: show may XML format records. Command show followed by 'format'
13 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
16 src/stemmer.c: Avoid using unnamed union. It is not supported by some
19 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
22 Update yaz.spec to operate on both SLES11 / Centos 5.5.
24 RPM: Release includes 'indexdata' name. Use indexdata in release name so
25 this package can be distinguished from other vendors.
27 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
28 as determined by configure
30 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
32 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
33 returns no error and no record, the present request is considered
34 partial (only a subset of the records could be returned by backend), and
35 so it is appropriate to set Present Status to partial-4.
39 Move yaz-config man pages to section 1.
41 More documentation about SOLR.
43 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
44 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
45 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
46 peers on some Linux systems. However, in general that does not work
47 so YAZ can not rely on that to work. Debian changed behavior in this
48 respect from Debian lenny to Debian squeeze (still testing as of Oct
50 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
52 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
56 Fix yaz-config output: echo_source not set correctly by configure.
60 SOLR WebService support for yaz-client and ZOOM.
62 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
66 Z39.50 facet support. Facet specifications are passed for search in
67 other-information with ASN.1 as defined in facet.asn and OID
68 .10.1000.81.5 . Facets are expressed as an Attribute list as known
69 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
70 3 is limit (number of entries to get in response). yaz-ztest returns
71 dummy facets if a client asks for them.
75 CCL fixes: bug 2895 and bug 3539.
77 GR1-display: add comma in display - was removed by mistake in
80 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
82 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
86 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
87 result set from a connection. The result set will be on its own
88 thereafter; no operations on it will perform retrievals from a target.
89 Only cached copies are returned.
91 ZOOM C:fix case for HTTP servers responding with Connection:close.
92 Ensure that if there is a current task it is resumed (like fetching
93 more records in a result set) . Bug #3484.
95 PQF parser: use odr_atoi for Odr_int (not atoi)
97 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
98 values that contain any non-digits are treated as string attributes
99 (previously decoding only checked for leading character ([0-9]). PQF
100 encoding: attribute string values are not surrounded by double-quotes.
104 New utility for managing threads - thread_create.h.
106 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
107 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
108 but YAZ' implementation do.
110 Fixes for yaz_cond-functions on Windows 7.
112 DLL export more symbols.
114 zoomsh: show record do NOT render opac.
116 Remove *.la files from Debian and RPM packages.
120 Debian package libyaz-dev depends on libgnutls-dev again (was
121 removed in YAZ 4.0.6, but due to Libtool it is still needed
122 even though yaz-config do not list libgnutls libs).
124 ZOOM: Use only one WRBUF for returning string results for
125 ZOOM_resultset. Reduces memory usage for ZOOM in general.
127 ZOOM: ZOOM_connection do not use a shared pointer to
128 ZOOM_resultset after ZOOM_resultset is destructed by
129 user. Reverts to YAZ 4.0.4 behavior.
133 record-conv: fix problem with at least one XSL conversion -
134 due to probably incorrect usage of XML XSL documents.
138 Fix yaz-config for static mode and the use of SSL (gnutls).
142 Forward decl timeval struct in mutex.h and gettimeofday.h.
144 yaz-config: fix 'static' mode linking.
148 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
149 are wrappers for pthreads or Windows. For Windows these are put in
150 a separate DLL: yaz_cond4.
152 libyaz.la (whole source) is compiled with thread. If thread support
153 is enabled enabled, all source of YAZ is compiled with treading support.
154 This allows core utilities such as yaz_log to use thread facilities.
155 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
156 thread utilities. This commit moves mutex utilities (mutex.c) from
157 libyaz_server.la to libyaz.la.
159 yaz-json-parse displays leading text until error.
163 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
164 patch from Giannis Kosmas.
166 SRU: no longer URL encode SRU database. The URL for an SRU server is
167 a URL and such is alreeady encoded - at least when given with leading
168 http:// or https://. This reverts behavior to YAZ 3.0.50.
170 Support for new MARC XML notation TurboMARC which like MARCXML is a
171 complete representation of MARC/ISO2709.. This one, however, is more
172 compact and allows for faster processing with XSLT. TurboMARC can be
173 used in the marcdisp.h API, from the yaz-marcdump utility and from
176 yaz-ztest can be configured - via the database - to perform certain
177 delays when it performs operations search, present and single record
178 fetch. This allows testers to make yaz-ztest act as a real or even slow
179 Z39.50 server. Refer to the yaz-ztest man pages for details.
183 wrbuf_destroy allows NULL WRBUF passed to it.
185 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
187 Add ZOOM_connection_close.
189 No fixed size buffers for ZOOM shell - bug #3257.
191 tstodr: make it work on s390 platform.
193 New icu iterator-functions. The new icu_iter-functions makes it possible
194 to use ICU chains from many threads.
196 yaz-client: better syntax check for show command.
200 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
203 New simple local-file XML include facility which allows file glob-patterns.
204 Refer to yaz/xml_include.h.
206 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
209 ZOOM_record_get supports new parameter "format" which makes it format XML
212 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
213 JSONText in ECMA-262) is JSONValue, not JSONObject.
217 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
218 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
220 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
221 POSIX/Unix builds .so with major version 4.
223 Remove old LOG_-defines from log.h. They have been obsolete and
224 undefined by default for the last 5 years.
226 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
228 GFS: Remove socket (int *fd) from search_rr handler. The socket
229 descriptor ptr is a facility that allowed a search handler to supply
230 a socket which would serve as a callback - when search was complete.
231 This facility has now been in use for years.
233 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
234 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
235 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
236 returns 'const char *' rather than 'char *. The returned string is
237 read-only and should not be modified by applications. COMSTACK cs_close is
238 now a void function - it no longer returns int. No applications check for
239 the value and the implementations has always returned 0.
241 ZOOM: use size_t for scan hit counts and str size. Functions
242 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
243 occ (hit count) and len (string length) are now of type size_t pointer
244 rather than int pointer. This is to be able to represent large hit counts
245 and to also just to use the proper type for string length (strlen result).
247 New JSON parser. Refer to include/yaz/json.h .
249 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
250 Used to be int in some cases. Many wrbuf_-functions used to return an int
251 indicating some length.. These return values were never used. And so they
254 ODR: odr_malloc, odr_total now takes size_t for size.
256 clone_z_type: fix leak; occurred for encoding failures.
258 --- 3.0.52 2009/12/03
260 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
261 bug was introduced in 3.0.51.
263 --- 3.0.51 2009/12/02
265 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
267 tcpip comstack: fix leak for getaddrinfo.
269 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
270 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
271 Decoding of SRU "path" database is performed by private function
272 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
273 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
275 yaz-client: honor base command for SRU. Change when database setting
276 is applied for SRU and ensure it is kept when a connection is reset.
277 Change also the way errors are displayed or SRU (decoding of packages).
279 --- 3.0.50 2009/11/02
281 Add support for extra request / response data for SRU codecs and GFS.
282 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
283 for extra data response buffer and length. For the GFS, both request
284 and response data (XML) is carried in extra_args and extra_response_data
285 for the search handler. Patch by Ko van der Sloot.
287 ZOOM: For queries that cannot be converted to the specified rpnCharset,
288 ZOOM now returns a diagnostic on the client-side ('invalid query' /
289 10010). This fixes bug #2113.
291 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
292 cmdfile included a 'quit' command that would result in a memory violation.
294 --- 3.0.49 2009/10/01
296 Make a number of functions defined in xmlquery.c static. These have
297 never been declared in a public header file (yaz/xmlquery.h) and was
298 made public by mistake.
300 Improve speed of character conversions (iconv utilities). This makes
301 conversions from MARC-8 faster.
303 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
304 unless type desired is "raw". This will prevent type "xml" from
305 returning ISO2709 .. Which obviously can not be XML parsed.
307 Fix memory leak in ZOOM that would occur if option apdulog was used
308 on a re-used connection.
310 Frontend server logs HTTP requests.
312 Frontend server now sends Z39.50 close when it times out (sesssion has
313 been idle for too long). Versions 2.0.30 and earlier also sent close.
314 But due to a mistake this was disabled in all versions after that, i.e.
315 the server would just close the socket immediately.
317 yaz-client emits a better message when receiving an unrecognised
318 userInformationField.
320 Skip zero-length subfields when decoding ISO2709. This rare case happens
321 if a record has two FS characters in a sequence. Without this patch
322 there would be a reference beyond char array in using_code_len fragments
325 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
327 --- 3.0.48 2009/08/28
329 The show command offered by the zoomsh command now takes a 3d optional
330 parameter type which is what is passed to ZOOM_record. If the type
331 argument is omitted, "render" is used.
333 RPN to CQL conv may use USE string attributes (bug #2978).
335 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
337 --- 3.0.47 2009/07/08
339 Function yaz_xml2query allows a diagnostic element in the PQF XML
340 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
341 code and additional info respectively.
343 The BER BOOLEAN is now the integral type Odr_bool which still happens
344 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
345 typedef'd to Odr_int. This is still an integral 'int', but it may be
346 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
347 ASN-1 compiler as well as programs has been updated to use the new types.
349 --- 3.0.46 2009/06/08
351 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
352 only the bibliographic record was rendered. For type=opac, an OPAC
353 record is only returned if it is present.
355 iconv: small fix for encoding of advancegreek.
357 yaz-client: avoid double display of SRU/SRW records (bug #2798).
359 yaz-client: option auto_reconnect=on really reconnects.
361 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
363 server: avoid null ptr ref for for yaz_poll errors.
365 build: fix RPM build for RHEL 5.3.
367 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
369 --- 3.0.45 2009/03/31
371 Fixed bug #2709: TCP connect returns Invalid argument.
373 Fixed compilation for mingw.
375 Honor charset for raw records (ZOOM_record_get).
377 Fixed use of errno for threaded mode that was seen on Solaris 10.
379 Fixed argument passing with blanks in value for Windows Service.
381 Disable YAZ' own log rotate by default (no 1 GB limit).
382 The variable l_max_size which specifies the log file limit is set to 0
383 (DISABLED): This is due to the fact that YAZ is most often deployed using
384 logrotate. Also YAZ can not perform log rotate because of unsufficient
385 permissions (setuid).
387 --- 3.0.44 2009/02/17
389 List supported encodings in man page for yaz-iconv.
391 Fixed missing SSL libs for --libs output
393 Re-established OID record syntax application-xml. Nobody should use it
394 but we don't want to change soname because of this symbol being absent.
396 --- 3.0.42 2009/02/02
398 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
400 Added member named_result_sets for init handler struct for the GFS. This
401 allows a server to disable named result sets.
403 Removed OID record syntax application-xml.
405 Added support for rule-based transliterator for ICU wrapper of YAZ.
407 Fixed bug #1902: yaz-icu XML output.
409 Make YAZ checks Emacs friendly.
411 BITSTRING value shows value. Bug #2346.
413 ISO2709 decoding: skip control characters from indicator data.
415 Omit sort key by default in yaz-icu's output.
417 Allow combined single char options (again) for YAZ' options function.
419 Utility yaz-marcdump got option to display YAZ version (-V).
421 Allow YAZ to use ICU 3.4.
423 Added new ICU test case which illustrates removal of diacritics.
425 --- 3.0.41 2008/12/29
427 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
429 --- 3.0.40 2008/12/29
431 For configure, using option --without-xml2 also disables Libxslt/Libexslt
434 Fixed bug #2352: yaz-marcdump crashes for certain record.
436 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
438 Added support for Danmarc2 to UTF-8 conversion.
440 Added support for ISO5426 to UTF-8 conversion.
442 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
443 implementation version.
445 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
447 --- 3.0.38 2008/11/10
449 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
450 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
452 ZOOM C now interprets databaseName option for ZOOM connection as path
455 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
457 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
459 Dummy Libxml2 types no longer defined in headers of YAZ'.
461 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
464 --- 3.0.36 2008/09/26
466 Various ODR chapter fixes.
468 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
470 Added missing source for Windows compilation, mutex.c.
472 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
474 For SRU connections in ZOOM all records up to "count" are now fetched.
476 Fixed crash in generic frontend server (and yaz-ztest) which occurred
477 in Windows due to bad error handling for Libxml2.
479 Added facility for sending arbitrary records (ASN.1 any) using
480 ZOOM C's Extended service update. Patch by Sam Reynolds.
482 New options for ZOOM C's connection, logapdu which makes ZOOM log
485 --- 3.0.34 2008/06/18
487 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
489 --- 3.0.32 2008/06/12
491 Fixed memory violation that could occur when decoding UTF-8. This bug
492 was only present in 3.0.30 of YAZ.
494 --- 3.0.30 2008/06/06
496 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
497 GNU TLS is used by default (if found).
499 yaz-ztest returns OPAC records if a client asks for OPAC.
501 Improved speed of MARC-8 encoding.
503 Added support for lossy and loss-less MARC-8 encoding.
505 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
507 Added new Windows Service wrapper (sc).
509 yaz-client's itemorder command may now send a file.
511 Fixed yaz-marcdump to allow the use of NS prefix for record element.
513 Added new function yaz_log_xml_errors.
515 Allow (but warn) unknown XML attributes in MARCXML parsing.
517 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
519 The UTF-8 to MARC-8 conversion now uses a different set of characters
520 for Greek symbols. Bug #2120.
522 --- 3.0.26 2008/02/21
524 Added yaz_daemon (daemon.h).
526 Fixed bug #2068: pkg-config trouble
528 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
530 --- 3.0.24 2008/01/28
532 Document --with-xml2 option.
534 Added OPAC XML XSD (etc/opacxml.xsd).
536 Allow glob mask for name attribute in retrieval element for the
537 generic frontend server's retrieval facility.
539 Changed yaz_poll_poll to return yaz_poll_except for all returned events
540 except POLLIN/POLLOUT.
542 Fixed error handling in cs_listen. Bug #2037.
544 --- 3.0.22 2008/01/20
546 Fixed version in yaz/yaz-version.h.
548 Fixed bug #2027: Crash when closing connection.
550 Changed configure so that ICU support is only enabled if only ICU
551 and Libxml2 is available (because the ICU chain is XML based).
553 --- 3.0.20 2008/01/15
555 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
556 is built. Only this DLL depends on the ICU runtime.
558 yaz-ziffy is no longer part of YAZ. It is distributed separately by
559 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
561 Changed license of CCL module to 'Revised BSD'. After consultation with
562 remaining members of the original EUROPAGATE consortium, we are re-issuing
563 the CCL module without a separate license. The software was developed by
564 Index Data as part of a research project. The special license was included
565 to help feed usage information back to the project consortium to support
566 project evaluation. At this time, the project consortium has long-since
567 disbanded, and the majority of the original principals have retired. At the
568 same time, we have significantly modified the software during the following
569 years, to the point where very practically no original code remains. To
570 simplify re-use of the software, we have contacted those members of the
571 consortium who could be reached, and agreed to re-issue the module as a
572 proper part of the YAZ package.
574 Tcl scripts uses /usr/bin/tclsh as preferred shell.
576 CQL closer to being version 1.2 compliant. CQL also allows free-form
577 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
580 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
581 bug could make Extended services handling crash in the ZOOM layer. This
582 bug was only present in YAZ 3.0.18.
584 --- 3.0.18 2007/12/19
586 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
589 yaz-marcdump reads and writes collection wrapped records.
591 Handle OPAC for record conversion module.
593 Fixes for ICU wrapper.
595 Allow ICU libs to be controlled with --with-icu .
597 --- 3.0.16 2007/11/12
599 Added yaz_poll which is a wrapper for select/poll. When poll is available
600 and non-buggy, it is used, by yaz_poll . This allows more than 1024
601 sockets to be in use.
603 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
604 functionality through an XML based configuration (ICU chain). This system
605 is useful for search facilities such as Pazpar2 and Zebra that needs to
606 perform tokenization of indexed material. The ICU code in a separate
607 library libyaz3_icu.a.
609 Added HTTP tunnel facility for COMSTACK, bug #1752.
610 This is a facility that allows a Web proxy, such as squid, to tunnel
611 Z39.50 traffic. This facility is "transparent" to must applications
612 using YAZ. It's enabled by using pseudo transport connect: followed by
613 the proxy address, followed by command, then follwed by he regular
614 "virtual" addresss. For example,
615 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
617 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
619 --- 3.0.14 2007/09/21
621 Fixed bad memory reference in ZOOM_record - cuased by member not being
622 initialized. This was a problem only in YAZ 3.0.12.
624 Fixed bug in conversion from MARC to XML: Non-XML characters in control
625 fields were not removed.
627 Changed the way C code is generated from codetables.xml. Made a MARC-8
628 conversion trie for each characterSet section rather than codeTable.
629 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
630 of codetables.xml from Larry Dixson, LOC. Bug #1464.
632 --- 3.0.12 2007/09/12
634 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
635 from ZOOM_record_error).
637 ZOOM C function ZOOM_record_get returns record schema for type="schema".
639 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
641 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
643 Better SRW-to-Bib-1 diagnostic mapping.
645 ZOOM C and yaz-client announces SRU version 1.2 by default.
647 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
650 Fixed in yaz_sru_decode to allow other version than 1.1.
652 --- 3.0.10 2007/08/22
654 Added support for SRU scan for ZOOM.
656 Added support for the use of the older versions or Extended Service
657 Update in ZOOM. To faciliate this, an option "updateVersion" may be
658 set to the version , 1=first, 2=second, 3=third. The third version is
659 what ZOOM C has used so far. And that, obviously, is the default.
661 Added support for CCL queries in Z39.50 queries sent to the GFS (and
662 therefore in Zebra and in SimpleServer-based applications). The new
663 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
664 qualifier file used to transform incoming CCL queries into Type-1 RPN,
665 which is passed into the back-end search callback function.
667 Added support for HTTP Basic authentication in clients: the SRU/W
668 codec encodes the username/password elements of the PDU structure
669 appropriately, and these may be set using the "user" and "password"
670 options in ZOOM-C applications (the same options that are used for
671 Z39.50 authentication).
675 Fixed bug #1208: SSL appears to be broken in ZOOM.
677 Fixed bug #1206: Libxml2 include path weirdness.
679 Added oid_name_to_dotstring.
681 Allow elementSetName to be specified for ZOOM C record update.
683 Allow waitAction to be specified for ZOOM C based for Extended Services.
685 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
686 syntax OID. Bug introduced in YAZ 3 series.
688 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
692 Fixed bug #1157: yaz-client does not read .yazclientrc from current
693 directory. yaz-client now reads commands from file given by option -f
694 if specified; then tries to read .yazclientrc in current directory.
695 Failing that, it reads .yazclientrc from user's home directory.
697 Added support for correlationInfo Note and ID for Record Update via
700 Added yaz-client command querycharset which specifies character set for
701 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
702 (termListAndStartPoint).
704 Charset ISO5428:1984 is an alias for ISO5428-1984.
706 Implemented a way to perform scan in a result set using Z39.50. This
707 is achieved by attaching the result set name in the characterInfo
708 (type InternationalString) of OtherInformation in the Scan Request PDU.
709 The result set is identified in the otherinformation by the new OID:
710 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
711 This allows for scan in result set and faceted search . Zebra did some
712 of this in the APT term using attribute type 8 and value being result
713 set. Using the OtherInformation approach for this is cleaner and easier
714 to work with in proxies and the like. This facility can be used in
715 yaz-client using new command setscan which takes a result set as first
716 argument, start position (APT) as second.
718 Changed decoding of SRU XML packed records to deal with servers that
719 have recordData with XML data with multiple root nodes. Also make
720 comparison for recordPacking case insensitive. Again, one server
721 returns "XML" where others return "xml".
723 For SRU responses allow Content-Type application/xml as well as text/xml.
727 Fixed bug in character set conversion of BER strings. Bug introduced
732 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
734 For OID class, use oid_class consistently.
736 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
739 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
740 character set for bibliographic information interchange". By Giannis Kosmas.
742 Added documentation on new OID API.
746 Changes to generic frontend server interface: added new member
747 'query_charset' for bend_initrequest structure. A backend init handler
748 should set this member to its native character set for query terms.
749 When defined, the frontend server logic will announce this character set
750 to a client if the negotiationModel bit is set by the client. All server
751 implementors are encouraged to specify this. If a backend server does not
752 specify this a warning is issued using yaz_log(YLOG_WARN,..).
754 Added CCL utility to remove terms (stop words) from resulting RPN
755 tree. This is handled by functions with prefix ccl_stop_words_ .
757 New ZOOM C option, "rpnCharset", which allows client-side conversion of
758 terms in RPN queries.
760 Clean-up the CCL API. Moved some internal structures from ccl.h to
761 private header cclp.h. Changed ccl_parser_create so that a Bibset must
762 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
763 This is replaced by ccl_parser_find_str which takes a string instead.
765 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
766 libyaz.la is the core of YAZ except the generic frontend server and
767 does not depend on POSIX threads anymore. libyaz_server.la is the
768 generic frontend server facilities and uses POSIX thread functionality
769 if available. The libyaz.la no longer depends on POSIX threads because
770 the number of global structures is limited. NMEM no longer re-uses blocks
771 between threads ; it simply free's memory immediately but allocates in
772 "large" chunks as usual. We don't expect any performance penalties
773 because of this. The yaz_log system is still using a global log_level so
774 caution must be taken when modifying it with yaz_log_init_.. +
775 yaz_log_mask_str. This, however, should not cause any trouble because
776 these functions are called during initialization of application code
777 anyway. `yaz-config --libs server` returns libs for server applications;
778 `yaz-config --libs` returns libs for non-server applications.
780 New OID database - with public definitions in oid_db.h. Removed old OID
781 database including the head oid.h and definitions such as enum oid_value
782 and struct oident. The new OID database uses the same string names as
783 before but the 'protocol' is gone. There are now only two representations
784 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
785 converts from string to OID; functions with prefix yaz_oid_to_string
786 converts the other way.
788 Change to emit_term() in CQL-to-PQF query translation: when a term has
789 the /regexp relation modifier, do not process it for leading and
790 trailing "^" and "*", which have quite different meanings in regular
793 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
794 write handlers no longer carries a 'last' parameter. This will make
795 yaz_iconv flush "less" characters. A flush is performed by call to
796 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
798 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
799 removed, because function yaz_query_to_wrbuf does the same.
801 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
802 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
804 Deprecated MARC utility functions removed.
806 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
809 Branch split: YAZ_2_1_55_branch
811 --- 2.1.54 2007/03/16
813 Fix to ZOOM-C so that transparent reconnection is properly handled on
814 connections that are in asynchronous mode.
816 Fixed compilation on OpenBSD 4.0.
818 Large strings in GRS-1 records are now properly displayed in yaz-client.
820 Added character conversion support for "advancegreek"; based on patch from
823 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
824 sequence is met. Before the error was not set so it would be unknown.
826 Adjust yaz-marcdump MARC reader so that it skips until record separator
829 --- 2.1.52 2007/03/07
831 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
832 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
833 fd_set structure used as a bitmask for the FDs to be selected on.
835 Using ACX_PTHREAD macro to check for POSIX threads.
837 Fixed have-vsnprintf check.
839 --- 2.1.50 2007/02/23
841 Fixes for configure on BSD. Bug #900.
843 Added snprintf/vsnprintf wrappers for systems that don't have
844 limits (heavens forbid).
846 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
847 created before all previous tasks were completed and removed from the
848 task queue, the new task could be removed by a mistake.
850 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
852 Implemented pass-through CQL-to-PQF conversions. Bug #861.
854 Fixed bug #832: Problem with MARC/charset in yaz-client.
856 Fixed bug #668: save command line history for yaz-client.
858 Fixed bug #830: pkg-config support.
860 --- 2.1.48 2007/01/23
862 Extended ZOOM result set options with two options that may be read by
863 a client: resultSetStatus and presentStatus with values as specified for
865 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
867 Fixed bug #827: Using SSL fails on Debian etch.
869 Fixed bug #826: Weird looking chars for set of MARC records.
871 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
872 that is treated as an ItemOrder with itemRequest being an XML document
873 external. The value of "doc" is the content.
875 Extended the GFS search facility. New member of bend_search_rr
876 'estimated_hit_count' signals that hits is known to be an estmate
877 (higher or lower than real hit count). New member 'partial_resultset'
878 signals that the search was partial (hit count is lower or equal than
879 real hit count). For Z39.50, the information is stored in resultSetStatus
880 member of SearchResponse APDU. For SRU, the information is signalled
881 via SRU diagnostic 59: "Result set created with valid partial results
884 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
886 --- 2.1.46 2007/01/13
888 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
890 Added ZOOM_connection_peek_event.
892 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
893 the following new functions:
894 ZOOM_event_nonblock, ZOOM_connection_process,
895 ZOOM_connection_get_{socket,mask,timeout},
896 ZOOM_connection_fire_event_{timeout,socket}.
897 The existing blocking event handler, ZOOM_event, is a wrapper for the
898 + blocking ZOOM_event_sys_{poll,select}.
900 Implemented function ccl_xml_config which parses XML version of CCL
901 configuration (bug #798).
903 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
905 Added timings utility (yaz/timing.h)
907 --- 2.1.44 2007/01/03
909 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
912 Fixed bug #779: Rotation of apdu.log fails.
914 Fixed for character set conversions:
915 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
916 Honor G1 set in MARC-8 decoding.
918 --- 2.1.42 2006/12/17
920 Fixed bug #775: char conversion does not handle Alternative UTF-8
923 Implemented function yaz_marc_read_line which parses MARC line format
924 records. There is a wealth of formats out there. So far, this function
925 reads line records produced by yaz_marc_write_line.
927 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
928 more generic and easier to remember(!) options: -i format and -o format
929 which specifies input format and output format respectively - where
930 format is one of "marc", "marcxml", "line", "marcxchange".
932 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
933 does not print anything except warnings for records.
935 For yaz-marcdump, added support for MARC split into files (-s) with a given
938 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
939 spec, at http://www.loc.gov/standards/sru/record-update/
940 This has changed the binary layout of the following structs:
941 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
942 bend_update_rr . Patch by Ko van der Sloot.
944 Added GFS utility function bend_assoc_is_alive which returns 1 if
945 association is still alive (client is connected); 0 otherwise (client
946 closed connection). This allows busy servers to stop working for
949 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
950 been a separate piece of software. This version of ziffy has been modified
951 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
953 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
955 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
956 Client code may now interrogate options such as "init_opt_sort" to
957 find out whether the server claims to support various options.
959 --- 2.1.40 2006/11/27
961 Added utilities yaz_{set,get}_esn to set/get element set name from
964 Removed the build of libyazthread.la. The libyaz.so is the threaded version
965 of YAZ and has been so since YAZ 2.1.10.
967 Implemented ZOOM_record_error which returns error information for
968 record (surrogate diagnostic).
970 --- 2.1.38 2006/10/31
972 Updates for SRU Update by Ko van der Sloot:
973 1. Changed name from "operation" to "action"
974 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
975 versions in the code, marked as 'backward compatible'.
976 3. Added diagnostics for SRU Update.
978 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
980 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
982 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
984 For GFS, fixed problem with SRU diagnostic 'First record position out of
985 range' being issued for 0 hits.
987 zoomtst10 part of Windows Build.
989 --- 2.1.36 2006/10/13
991 Implemented yaz_filepath_comp which splits a path into file path
992 components (required by Zebra 2.0.3+).
994 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
995 BSD inspired license until now so this should not have any real impact on
996 anybody. See http://www.opensource.org/licenses/bsd-license.php
998 Fixed bug #687: Missing log lines.
1000 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1003 Fixed bug #689: SRU diagnostics to be added.
1005 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1006 whether a connection is idle (no more work do do).
1008 --- 2.1.34 2006/10/04
1010 Change type of optval from long to int for invocation of setsockopt with
1011 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1013 Added support for specifying the max log file size for the Generic
1014 Frontend Server. The size is given with option -r.
1016 --- 2.1.32 2006/09/21
1018 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1020 --- 2.1.30 2006/09/17
1022 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1025 Fixed bug in Generic Frontend Server that could cause a server to stop
1026 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1028 For the generic frontend server, the maximum record size is used as maximum
1029 size of incoming packages (SRU + Z39.50). The value until was previously
1030 only used in Z39.50 Init negotiation and, later, in a session controlled
1031 sizes of records returned. This is controlled using -k option. It can be
1032 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1034 --- 2.1.28 2006/09/04
1036 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1039 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1041 New option for yaz-marcdump -lpos=value which allows setting a portion
1042 of MARC header to a certain value.
1044 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1046 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1047 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1049 --- 2.1.26 2006/08/15
1051 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1054 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1056 --- 2.1.24 2006/08/08
1058 Fixed MARC ISO2709 encoding routines to deal with character set
1061 Minor changes to GFS logging. Database included in search request log
1064 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1065 cached/multiple records.
1067 Shared libraries are built by default on Unix+configure.
1069 Changed cql2pqf transformation to use a different evaluation order. The
1070 new order is: always, relation, structure, position, truncation, index
1071 and relationModifier. Old order was: always, relation, relationModifier,
1072 structure, index, position, truncation. Note that the the latter ones
1073 override former ones for identical attributes.. The new scheme means that
1074 it is possible to override any existing attribute with a relationModifier.
1075 And also that it is possible to override everything for the index rule
1076 (except the ones listed in relationModifier). No order is perfect but this
1077 one, we believe, covers more real cases.. The "always" should have been
1078 called "default", since the attributes there can be overridden with all
1081 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1082 compilation phase, but also for yaz-config --cflags output. This allows
1083 us to have public headers with Libxml2 stuff in them . It should also,
1084 eventually, make Libxml2 checks redundant in packages using YAZ, such
1087 --- 2.1.22 2006/06/15
1089 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1090 stored in uri, message and details.. Previously diagnostics were stored
1091 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1092 compatibility.. but he's probably the only one affected, so.
1094 Added support for CCL, compiled on the client side, in ZOOM-C. This
1095 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1096 input; the resulting query objects can be used for for searching with
1097 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1099 YAZ' configure searches for OpenSSL by default.
1101 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1102 SL_CTX_use_certificate_file. See
1103 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1104 for more info. Thanks to Ko van der Sloot.
1106 --- 2.1.20 2006/06/02
1108 Bug #600: SRU GET, POST support for yaz-client. Introduced
1109 command 'sru' which selects method SOAP/GET/POST.
1111 Allow missingValueAction to be specified for the sortspec string -
1112 function yaz_sort_spec. By default, the missing value action is null.
1113 Use ! to specify "abort". Use = followed by stringvalue to specify default
1116 Ensured that Present-handler (if defined) is called in GFS before any call to
1117 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1118 searchRetrieve requests.
1120 Documentation for YAZ is now based on the Docbook XML/XSLT using
1121 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1122 is no longer depending on jade/openjade or docbook-to-man scripts.
1123 PDF is no longer part of the distribution - but can optionally be
1124 made using DSSSL/jadetex or FOP.
1126 Added retrieval handling support in Generic Frontend Server to support
1127 conversion between MARC/XML as well as XSLTtransforms. See
1128 etc/yazgfs.xml for an example.
1130 Added Authentication support to Generic Frontend Server in SRU
1131 mode. Authentication using HTTP Basic is supported, as is the use
1132 of 'x-username' and 'x-password' parameters in the request itself.
1134 Added support for a new character set MARC8s identical to MARC8 except
1135 that it converts combined characters to single Unicode characters in the
1136 Latin-1 range (when possible).
1138 --- 2.1.18 2006/04/24
1140 ASN.1 compiler 0.4: generates brief Doxygen file header for
1141 generated .h/.c files.
1143 Utility yaz_iconv now supports conversion to MARC-8.
1145 New facilities for the MARC module. The reading - and writing of
1146 content are separate methods for the yaz_marc_t handle. The following
1147 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1148 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1149 format). Write functions have prefix yaz_marc_write_.. The existing
1150 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1151 available. Removed support for OAI-MARC and simplexml (not the
1152 simplexml from PHP5).
1154 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1155 to be returned for this connection.
1157 --- 2.1.16 2006/03/31
1159 Allow multiple languages and charsets to be specified with
1160 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1161 negcharset iso-8859-1,utf-8
1163 Translation of proximity nodes from CQL into PQF now works.
1165 Moved to automake 1.8, 1.9.
1167 Added function yaz_log_set_handler which allows a log handler to be
1168 installed. This handler will be called for all log messages. Output
1169 to file is also produced; but that can be disabled by passing NULL
1170 fname to yaz_log_init_file.
1172 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1174 For SRW (including GFS), accept application/soap+xml as content-type
1177 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1178 produces NO stylesheet reference even if a default stylesheet is specified
1181 --- 2.1.14 2006/03/14
1183 Updated Windows package to include yazd.dll + yazd.lib for the
1184 Development component.
1186 If the environment variable YAZ_LOG is set, then it is used as a
1187 string indicating the default level of logging to use if not
1188 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1189 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1190 used as before. So, for example, to omit warnings from YAZ logging,
1191 export YAZ_LOG=-warn
1193 cql_transform() now map structure and other attributes before indexes,
1194 so that index-specific structures and other attributes can override
1195 defaults. So now a combination of mapping specifications such as:
1197 index.dc.date = 1=date-modified 4=5
1198 does the right thing.
1200 cql_transform() now also respects the "always" mapping specification,
1201 which establishes an initial set of attributes to be used for all
1202 terms except where overridden by more specific attributes associated
1203 with the index, relation or modifier.
1205 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1206 which mode to use; one of "post", "get" or "soap" (SRW, default).
1208 Fixes for yaz_iconv routines: changed trie-based character set conversions
1209 to use only non-negative values for bit fields due to Sun's C compiler not
1210 supporting negative values.
1212 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1213 sequences where not read correctly. Fix by Rustam Usmanov.
1215 Updated win/makefile to use options, settings which makes things
1216 compile with VS C 2005.
1218 --- 2.1.12 2006/02/01
1220 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1222 In ZOOM socket code, use select instead of poll on MacOSX.
1224 ZOOM-C now support client-side compilation of CQL into RPN that is
1225 sent to the server, enabling CQL to be used against all Z39.50
1226 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1227 ZOOM_query object, and submit it using ZOOM_connection_search().
1228 The CQL-to-RPN translation uses a configuration file, the name of
1229 which must be specified in the Connection's "cqlfile" option.
1231 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1232 function, which takes as its start-term parameter a ZOOM_query object
1233 (which may have had either CQL or RPN set into it).
1236 --- 2.1.10 2005/11/29
1238 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1239 GFS to support this as well. Backend handler, bend_srw_update, does the
1240 update work. Code contributed by Ko van der Sloot.
1242 Allow retrieval of Search Result-1 information in ZOOM by the use of
1243 options that are attached to a result set. ZOOM documentation updated
1246 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1247 UTF-8 conversion. Patch by Raj Patel.
1249 Added option -m to GFS to control formatting of timestamps in log file.
1251 Added 'exit' as synonym for 'quit' in yaz-client
1253 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1254 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1255 for the new members. Patch by Ko van der Sloot.
1257 Added support for SRU POST. It is supported for content-type
1258 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1260 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1261 Instead make the library libyaz.la multi-threaded. Threading as a whole
1262 can still be disabled by configure option --disable-threads. Previosly,
1263 with older GLIBCs there were problems with MT libs under Apache. This
1264 has now been fixed a long time ago.
1266 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1269 CQL module modified to be case insensitive for relations/indexes/operations.
1271 Fixed bug in CQL transform code: incorrect value relationModifieder
1274 Added 'show all' command for yaz-client which retrieves all results
1277 Added new yaz-client, xmles, which takes a (private) OID and
1278 a document to be sent as an extended service request.
1280 Describe new yaz-client commands wait_response and set_auto_wait.
1282 Increase TCP/IP listener backlog from 3 (which I am guessing was
1283 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1284 that the socket will queue as many incoming connections as it's able
1285 to handle ongoing connections. In other words, it will never now
1286 refuse a connection that it would be able to handle merely because
1287 it's not got around to accepting() enough of the pending connections
1288 yet. This is the behaviour anyway under Linux, where the listen()
1289 argument is ignored; but not under BSD and on systems such as
1290 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1291 YAZ-based servers should now be uniform across operating systems in
1294 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1295 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1296 This allows yaz-marcdump to read large MARC batches (>2 GB).
1298 Modified all YAZ source files - except the source which is auto-generated
1299 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1302 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1303 corresponding to the existing *_setl() function. These allow option
1304 values containing arbitrary valuues.
1306 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1307 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1308 except that it returns an indicator of whether or not the sort
1309 criterion was accepted (0 for OK, -1 for invalid).
1311 --- 2.1.8 2005/06/07
1313 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1314 MARC output rather than returning "new" buffer.
1316 yaz-client warns about unknown init options.
1318 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1320 --- 2.1.6 2005/05/24
1322 Added support for SRW sort in Generic Frontend Server. Patch
1323 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1324 sortKeys - or NULL if none is provided.
1326 Fixed bug #307: It was impossible to specify indefinite/no timeout
1327 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1330 Added support for multiple languages and charsets to be specified in
1331 ZOOM. Each charset/language is separated by a blank. If negotiation is
1332 in effect in init-response, Option
1333 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1334 Code based on patch by Vasiliy Osadchuk.
1336 Fixed bug #306: infinite recursion that occurred when calling
1337 yaz_log_level_init as the first call (before other log level or
1340 Fixed bug in scan handling in front end server: if preferred-Position-In-
1341 Response was non-present, a NULL pointer referece was performed.
1343 --- 2.1.4 2005/04/26
1345 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1346 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1347 now defined for all those error codes. So instead of putting 109 in
1348 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1349 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1351 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1354 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1356 Program yaz-client now exits and produces an error message if multiple
1357 Z39.50 servers are specified on the command line (none or one allowed
1360 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1363 --- 2.1.2 2005/03/16
1365 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1367 Fixed bug #272: Preserve spacing for CCL terms.
1369 --- 2.1.0 2005/03/14
1371 Added support for virtual hosts and multiple backend servers for
1372 the YAZ frontend server. The configution is XML based and
1373 support specificition of CQL to RPN mappings and explain information.
1374 See section "Virtual Hosts" in the YAZ manual.
1376 Extended OPAC display utility. OPAC display utility renders
1377 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1378 to supplement yaz_marc_decode_wrbuf.
1380 Fixed a bug in MARC decoder that could caused it to crash for some
1381 invalid MARC records. More diagnostics and warnings where added in
1382 XML output (warnings, etc are stored in comments).
1384 --- 2.0.34 2005/02/08
1386 Fixes for UNIX domain sockets. Bug #261.
1388 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1390 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1391 Added yaz_marc_subfield_str which defines subfield lead string which is
1392 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1393 yaz_marc_endline_str which defines end of fields string used in
1394 YAZ_MARC_LINE format. Default string is newline.
1396 Experimental support for MarcXChange. This format can be produced
1397 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1398 http://www.bs.dk/standards/MarcXchange.xsd
1400 Added yaz-client commands scansize that sets maximum number of
1401 entries to be returned by scan.
1403 --- 2.0.32 2005/01/11
1405 Added support for SRW scan in yaz-client and Generic Frontend Server.
1407 * Added whereInList member to SRW Scan Term.
1409 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1411 Fixed NMEM system to return aligned blocks on the smallest boundaries
1412 that are suitably aligned for all possible types on the particular
1413 architecture YAZ is being built for.
1415 --- 2.0.30 2005/01/04
1417 Fixed numerious warnings that was issued with newer versions of GCC.
1419 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1420 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1423 Make YAZ Generic Frontend Server slightly faster.
1425 Enhance (and reduce) logging for Generic Frontend Server.
1427 Revert YAZ log system so that it flushes every write operation
1428 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1430 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1431 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1432 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1433 will effectively disable old definitions.
1435 --- 2.0.28 2004/11/09
1437 Added yaz_log_time_format which specifies log format using
1440 Added yaz_log_module_level which returns mask for a module. Value
1441 is non-zero mask a if module is enabled; zero if disabled.
1443 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1444 in include/yaz/cql.h.
1446 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1448 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1450 Fixed bug #172: RPM builds does not enable SSL.
1452 Doxyfile.in part of dist. Doxyfile generated by configure.
1454 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1455 are given and the corresponding component does not exist.
1457 Extend CCL documentation in YAZ reference. Describe r=r.
1459 --- 2.0.26 2004/10/01
1461 Fixed MARC->MARCXML conversion to properly deal with
1462 fields, subfields, indicators having non-ASCII characters.
1464 Fixed MARC->MARCXML conversion so that ASCII control characters
1465 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1468 Added YAZ GFS support for conversion from Z39.50 surrogate
1469 diagnostics to SRW surrogate diagnostics.
1471 Bug fix: YAZ GFS did not return schema in explainResponse.
1473 --- 2.0.25 2004/09/30
1475 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1476 now converts recordSchema to elementSetName as well as schema URI.
1478 Fixed bug in COMSTACK that prevented HTTP request packages from being
1481 --- 2.0.24 2004/09/29
1483 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1484 does not require white-space before and after the dash in a range, e.g.
1485 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1488 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1489 due to new GCC removing "redundant" code.
1491 Added yaz-client commands scanpos and scanstep that sets preferred
1492 position and step-size for scan.
1494 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1496 Added CCL utility ccl_qual_buf which parses one or more CCL
1497 spec lines in a buffer.
1499 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1500 of name and value - ignoring empty lines and comments.
1502 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1504 Added odr_get_element_path which returns current element path for an
1505 ODR handle. This utility is useful in error handling or user-defined
1508 Added ODR_PRINT utility odr_set_stream which is is a more generic
1509 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1510 to a write function and pointer to close function. The close function - if
1511 non-NULL - will be called during odr_destroy.
1513 Fixed bug in CCL parser where truncation char was not removed from
1514 right side when truncation=both was in effect.
1516 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1519 --- 2.0.23 2004/08/11
1521 Fix buffer overrun in CQL parser when dealing with proximity (%).
1523 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1524 to UTF-8/UCS conversion is now only based on codetables.xml.
1526 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1528 --- 2.0.22 2004/08/06
1530 Add support for more "commit changes" in ZOOM (uses Extended Services).
1532 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1535 Yet another small fix for configure of SSL.
1537 --- 2.0.21 2004/05/14
1539 Fix SSL libs for configure when --with-openssl=DIR is given.
1541 --- 2.0.20 2004/05/10
1543 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1545 SSL comstack now uses yaz.pem certificate file on server side
1546 by default. Certificate filename can be configured by calling
1547 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1549 Fix bug regarding multiple calls to ZOOM_connection_connect.
1551 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1553 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1554 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1556 ZOOM now allows inspection of X509 peer certificate for verification.
1557 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1559 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1560 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1561 as "modular" but it simplifies things.
1563 Added cs_get_peer_certificate to that returns peer X509 PEM.
1565 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1566 NULL if SSL is unavailable.
1568 Documentation about MARC decoding tools.
1570 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1572 --- 2.0.19 2004/03/30
1574 Rename CHANGELOG to NEWS to follow GNU style packing.
1576 Fix bug with missing initialization of member in init_diagnostics.
1577 This bug affects threaded version of GFS server.
1579 --- 2.0.18 2004/03/20
1581 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1584 Ensure zlib.dll is packed with Windows install.
1586 --- 2.0.17 2004/03/17
1588 Fix encoding of xsd:string to use text instead of CDATA.
1590 Fix endless loop in CQL parser with unbalanced ".
1592 Use a more compact way to store MARC-8 conversion tables.
1594 --- 2.0.16 2004/03/16 Debian only
1596 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1599 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1604 --- 2.0.15 2004/03/01
1606 Another fix for decoding of XML packed records.
1608 --- 2.0.14 2004/02/25
1610 Fixes for Chunked encoding. White space not ignored after length spec.
1612 Update NS and use default NS for SRW diagnostic elements.
1614 --- 2.0.13 2004/02/23
1616 Implement ZOOM_resultset_cache_reset which resets record cache.
1618 Implement ZOOM_resultset_sort which sorts a result set.
1620 Implement chunked HTTP transfer.
1622 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1624 --- 2.0.12 2004/02/16
1626 Added member 'schema' to bend_explain_rr structure so that backend
1627 can specify explain record identifier. Defaults to Zeerex 2.0.
1629 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1631 --- 2.0.11 2004/02/16
1633 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1636 Added init command for yaz-client which sends "extra" init request.
1638 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1639 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1641 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1643 Make ZOOM error code for "invalid query".
1645 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1647 --- 2.0.10 2004/02/05
1649 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1652 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1654 Added option -p <file> to make Generic Frontend Server to write PID file.
1656 Added option -D to put Generic Frontend Server in background on its own.
1658 Make ZOOM C recognize option "password". If unset, "pass" is used
1659 (for backwards compatibility).
1661 Fixed a bug in Generic Frontend Server that could make it crash if a
1662 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1665 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1666 Must be issued before open, in order to be in effect.
1668 --- 2.0.9-6 2004/01/12 Debian/Windows
1670 Make the SRU server more picky WRT unknown params, etc.
1672 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1674 New YAZ client command, options, that sets Z39.50 options.
1676 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1677 options from a string of tokens (one token for each option bit).
1679 Update SRW diagnostic code messages.
1681 --- 2.0.9-5 2004/01/07 Debian/Windows
1683 Handle user defined stylesheet for SRW/SRU.
1685 --- 2.0.9-4 2004/01/06 Debian/Windows
1687 Fix bug in decoding of Content-Length.
1689 --- 2.0.9-3 2004/01/06 Debian/Windows
1691 Fix a bug with decoding of XML packed records.
1693 --- 2.0.9-2 2004/01/05 Debian only
1695 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1697 Fix bug in SRW/SRU diagnostics decoding.
1699 --- 2.0.9 2004/01/05
1701 Fixed bug in Generic Frontend Server which could drop records exceeding
1702 preferred message size. Reported and fixed by Irina Dijour.
1704 Fixed calculation of package size for structured records in Generic
1705 Frontend Server. Reported and fixed by Irina Dijour.
1707 Fixed namespace for SRW/SRU diagnostics.
1709 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1711 --- 2.0.8 2003/12/22
1713 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1714 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1717 CQL changes to reflect recent changes to the specification:
1718 * Documentation talks about context sets instead of index sets.
1719 * Documentation talks about indexes instead of qualifiers.
1720 * The CQL-to-PQF transformer's configuration file now uses
1721 "index.set.name = <attributes>" instead of the old form
1722 "qualifier.set.name = <attributes>". (Both forms are still
1723 understood but the latter is deprecated.)
1724 * CQL terms with no explicit index specified are now interpreted as
1725 cql.serverChoice instead of srw.serverChoice (which of course
1726 behaves exactly the same.)
1728 --- 2.0.7 2003/12/16
1730 MARC conversion can now generate ISO2709 output in another
1731 character set. yaz-marcdump uses this facility if you invoke it
1734 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1735 functions from there can be used from C++.
1737 --- 2.0.6 2003/12/04
1739 Frontend server now transfers memory from decoded packages to stream
1742 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1743 references to show up.
1745 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1746 the ZOOM Abstract API. The older names for the same options are still
1747 also supported for the benefit of old applications.
1749 ZOOM-C supports "implementationId" and "implementationVersion" options
1750 to go along with "implementationName". These allow the user code to
1751 specify identification strings to be sent to servers.
1752 Add OID for the new ExtLite attribute set.
1754 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1755 as requested/supplid by Ere Maijala <ere@atp.fi>
1757 For generic frontend server, reverse the order of
1758 "toolkit-supplied / application-supplied" strings sent as implementationId,
1759 Name and Version. Also, remove the spaces around the slash. This brings
1760 the GFS in line with the behaviour of ZOOM-C on the client side.
1762 Add function ZOOM_scanset_display_term.
1764 yaz-client shows scan displayTerm if present.
1766 Utility yaz-iconv is now installed by default along with the man page
1769 Extend configure check for OpenSSL to use pkg-config where available (such
1772 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1773 server to specify uid/gid/mask for socket using the format
1774 unix:[user=uid,][group=gid,][umask=mask,]file=path
1775 If file= is omitted the existing format is assumed, e.g.
1777 in which case the mask is 0666 (rw for everybody).
1779 Major restructure of YAZ source. All source in libyaz is in src directory.
1780 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1781 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1783 Added man page for utility yaz-marcdump (used to be called marcdump).
1784 yaz-marcdump is installed by 'make install'.
1786 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1787 of incoming package failed.
1789 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1791 Change prototype of odr_perror: add const to message string.
1793 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1795 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1796 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1797 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1798 DNS lookup. There should not be any compatibility problems with this
1799 assuming that blocking=1 or 0 is used.
1801 Fix bad reference in UNIX comstack in function cs_addrstr.
1803 Fix for compilation on AIX.
1805 The generic front-end server (server/seshigh.c) now supports returning
1806 Init diagnostics to the client in User-information-field, in
1807 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1810 --- 2.0.4 2003/09/04
1812 Allow any CQL relation (not just all,any,exact,scr).
1814 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1815 that features the same UI.
1817 Implemented command update0 in YAZ client which is equivalent to
1818 update but uses old of Ext Update ASN.1.
1820 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1821 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1822 Previously no OID was used for this info.
1824 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1825 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1826 returns 'malformed search term' otherwise.
1828 SortResponse member resultCount now set to NULL in sort handler of
1831 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1834 Add three new utility functions for translating OIDs between various
1835 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1836 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1837 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1838 char *oid_to_dotstring(const int *oid, char *oidbuf);
1839 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1841 Reverted modifications for ES Update definition for z_IU0Update
1842 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1843 is back to YAZ 2.0.2.
1845 String value attributes for CCL parser.
1847 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1848 which their FirstSearch server returns in Init responses, sometimes
1849 carrying useful diagnostic information when Init fails. This has the
1850 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1851 "z39.50/oclcui.asn", where its definition is somewhat different from
1852 what OCLC document on their web-site, as required to interoperate with
1855 Support for anonymous authentication in yaz-client. Use the command
1858 * Fix the OID of the Index Data-local "admin" Extended Service from
1859 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1860 the 1000, which indicates a locally-defined OID, was a mistake.
1862 --- 2.0.3 2003/06/20
1864 Fix CCL directive @case handling so that it affects string match for
1865 both CCL keywords and qualifiers.
1867 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1868 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1869 Decoder has been updated with ASN.1 changes as listed in
1870 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1871 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1872 z_IUUpdate, remains unchanged.
1874 ZOOM_record_get may now return a record in a specific character set.
1875 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1876 "from" is the character set of record as returned by target. "to" is
1877 the character set to be returned. If omitted, "to" is UTF-8.
1879 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1881 New ODR utility, odr_getelement, which returns name of element for
1882 which encoding/decoding failed.
1884 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1885 in cases where a required element was omitted.
1887 Bug fix: some MARC8 sequences were not converted.
1889 New ZOOM option "step" which specifies number of records to be
1890 retrieved in one chunk. Used in conjunction with "start" and "count".
1892 SRW support for yaz-client. Use scheme http: to use it, e.g.
1895 yaz-client no longer does (un)intelligent character set conversions
1896 by default. Can be enabled with charset and marc_charset commands.
1898 xmalloc trace fix for 64-bit systems such as DEC alpha.
1900 Solaris 2.6 compile fix.
1902 New function, cql_strerror() translates SRW error codes, as returned
1903 by cql_transform_error(), into human-readable English strings. Used
1904 in yaz-client diagnostics when appropriate.
1906 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1907 converts it into a type-1 query which is sent to the server. This
1908 makes CQL available for use with all Z-servers, as opposed to the tiny
1909 minority that can handle CQL queries themselves.
1911 --- 2.0.2 2003/04/28
1913 New Debian package layout similar to the Redhat Package layout.
1915 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1916 and search result respectively.
1918 --- 2.0.1 2003/04/25
1920 Redhat package is now several packages: libyaz (runtime libraries),
1921 libyaz-devel (development and documentation, and yaz (utility programs).
1922 Package spec file by Morten Bogeskov.
1924 New member 'schema' in struct bend_fetch_rr which the name of requested
1925 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1926 handler MAY set this to reflect the schema of the returned record.
1928 New member 'display_term' in struct scan_entry. GFS now sets member entries
1929 and allocates scan entries to be filled by user scan handler. In previous
1930 version, entries member was allocated by the scan handler. That still works,
1931 but the GFS will ignore member display_term - assuming it was NOT set by
1932 the handler. The fact that the GFS now allocates the entries both allows
1933 for new members and makes a scan handler easier to write.
1935 Fix CQL lex buffer overflow.
1937 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1938 SRU default recordPacking is string.
1940 SRU protocol support for frontend server.
1942 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1944 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1946 Added scan for the ZOOM shell (zoomsh).
1950 * String Identifers for Schemas (Amendment 5).
1951 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1952 Old definition for schema
1953 Odr_oid *schema; /* OPT */
1958 Z_InternationalString *uri;
1959 #define Z_Schema_oid 1
1960 #define Z_Schema_uri 2
1963 * resultCount parameter to Sort Response (Amendment 1).
1964 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1966 Support for SRW 1.0 over HTTP. This is an optional feature and
1967 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1970 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1971 on the same port. SRW SearchRetrieveRequests are mapped
1972 to bend_init,bend_search,bend_fetch,bend_close.
1974 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1976 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1977 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1979 ZOOM connections are SRW based if schem http is used for hostname
1980 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1981 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1983 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1984 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1985 distance=n, order=true/false, relation=le, prox unit=word. If
1986 n is omitted, distance 1 is used.
1988 Fixed problem with C compiler include path in wrong order.
1990 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1991 on Solaris. Patch from Ko van der Sloot.
1993 New MARC decode API. All new functions operate on a yaz_marc_t
1994 handle. The most important new functions are: yaz_marc_create,
1995 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1996 decode and destroy respectively. Decoder can produce formats
1997 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1998 include/yaz/marcdisp.h.
2000 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2001 to UTF-8, UCS-32, wchar_t or Latin-1.
2003 * Prototypes for yaz_iconv_-functions moved to separate header
2004 include/yaz/yaz-iconv.h.
2006 Make a few private functions 'static' in unix.c. This prevents
2007 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2009 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2010 are set when Init Response is received.
2012 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2013 but returns diagnostic set as well.
2015 New function yaz_strerror which is a portable wrapper for
2016 strerror/strerror_r/GetLastMessage.
2018 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2019 is returned for MARC. If type is "oai", then OAI MARC is returned.
2021 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2024 --- 1.9.2 2002/11/26
2026 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2028 Fix bad race conditions on SIGTERM and terminate gracefully in
2031 Move retrieval (data1) module to Zebra since nobody seems to be
2034 Add GRS-1 render for ZOOM using same format as yaz-client.
2036 --- 1.9.1 2002/10/05
2038 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2040 Fix broken ESpec handling in data1 module.
2042 SGML reader parses comments and makes them part of the data1 tree.
2044 Added several type casts so that YAZ compiles as C++ code.
2046 ZOOM didn't handle PDU encoding failures properly.
2048 Added more Bib-1 diagnostics (approved extensions).
2050 GNU configure: better check for iconv.
2052 More portable use of accept, getpeername. Check for socklen_t. Use
2053 int/size_t if socklen_t is not defined.
2057 PQF parser rejects bad queries - including those with extra
2058 characters in them. PQF parser used to silently ignore that.
2059 Cleaner API for PQF added, which allows you to get detailed
2060 error information for bad queries (see yaz/pquery.h).
2062 Fixed bug in ZOOM_record_get for type "database".
2064 Implemented mini iconv library supporting conversions between
2065 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2067 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2069 --- 1.8.9 2002/08/20
2071 Fixed ZOOM C record cache so that preferredRecordSyntax and
2072 elementSetName is used to check for already fetched records.
2074 --- 1.8.8 2002/08/02
2076 Added three members in bend_initrequest structure to facilitate
2077 character set negotiation.
2079 Fixed a bug in frontend server that could cause indefinite
2080 loops under rare conditions.
2082 Revised character set utilities (charneg.h) so that encoding
2083 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2085 For PQF, directive @term <type> sets term type for Scan/Search.
2086 Here <type> is general, string, numeric, null. The term type
2087 is inherited - just like @attr.
2089 New call odr_set_charset that sets character set conversion for
2090 international-strings on a ODR stream. Prototype is:
2091 int odr_set_charset(ODR o, const char *to, const char *from);
2092 The InternationalString is still represented as C string in YAZ
2093 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2094 won't). On the protocol level, you can use any encoding.
2096 Support for UNIX sockets in ZOOM.
2098 Solaris recv sometimes returns errno == ENOENT. It is treated as
2099 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2101 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2102 both client and server. Code by Morten Bogeskov.
2104 --- 1.8.7 2002/05/22
2106 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2107 that they can be used directly from Visual Basic. You must recompile
2108 your windows APP if you're using ZOOM.
2110 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2111 Commands "lang" and "charset" sets language and character set respectively.
2112 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2113 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2115 Attributes from multiple CCL fields may be OR'ed rather than merged
2116 using directive "@field or". Fields are still merged by default -
2117 equivalent to "@field merge".
2119 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2122 Fixed bug in zget for parameter ExtendedServicesResponse.
2126 --- 1.8.6 2002/03/25
2128 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2130 Client displays USR.1:SearchResult-1 (hits per term).
2132 Additional Search Info for search in Generic Frontend Server.
2134 Fixed CCL parsing of "field=s".
2136 WIN32 installer - using the excellent NSIS software from nullsoft.
2138 Fixed CCL parsing of "field = - <number>".
2140 Added function yaz_marc_decode that decodes MARC for line mode
2141 display or XML (similar to that used by JZKit).
2143 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2144 Z39.50. But ISO/ILL was, however.
2146 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2147 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2149 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2150 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2152 --- 1.8.5 2002/02/03
2154 New YAZ client features: Command completion and new commands:
2155 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2156 Code provided by Jacob Poulsen.
2158 New call oid_trav, that visits all registered OIDs via callback.
2160 Function ZOOM_record_get now returns const char pointer rather than
2161 void pointer. It saves a lot of type casts.
2163 For YAZ client, command "auth" now allows you to set authentication
2164 in IdPass style. It is enabled when three tokens are given - order
2165 is user, group and password.
2167 Fix memory leaks in MARC record handling for ZOOM.
2169 New option for YAZ client, -k <kilobytes> that sets
2170 maximum record size. Similar to -k option for generic frontend
2171 server and yaz-ztest.
2173 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2175 Prefix query parser reports "fail" when bad attribute set is given.
2177 Fix in MARC decoder. Proximity logging. Fix for attribute set
2178 in scan handler for server. Patches by Shigeru Ishida.
2180 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2183 Configure option --with-openssl=<dir> now works when a directory is
2184 specified. Patch provided by Morten Bogeskov.
2186 New option for YAZ client, -u <auth>, that sets authentication.
2188 ZOOM fix: error information was sometimes "missing", since error
2189 was cleared/reset too when it shouldn't.
2191 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2193 --- 1.8.4 2002/01/04
2195 Scan for ZOOM API. New object ZOOM_scanset. New functions
2196 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2197 ZOOM_scanset_destroy.
2199 New ZOOM function, ZOOM_connection_last_event, that returns type
2200 of last event (such as "receive data", "send data", "apdu received",
2203 New ZOOM option, schema, that specifies schema for retrieval.
2205 New CCL feature. Qualifiers can be aliases for one or more
2206 other qualifiers (if more than one is given, OR is used).
2208 ZOOM uses named result sets if target supports it.
2210 Two new YAZ client commands: . (dot, which sources a script of YAZ
2211 client commands), and ! (to execute shell command.). Implemented
2214 Working on Debian packages.
2216 --- 1.8.3 2001/11/19
2218 YAZ client enables named result sets only if target supports it.
2220 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2222 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2223 with key="host" to get same result.
2225 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2226 Function Z3950_resultset_record(s) returns references to records
2227 "owned" by resultset. To become owner use Z3950_record_clone.
2229 Function z_ext_record handles Extended Services. Thanks to
2232 --- 1.8.2 2001/11/12
2234 CCL Parser fix: ignore token comma when dealing with and-lists.
2236 Documentation updates for COMSTACK.
2238 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2239 Changed prototype Z3950_records. For some functions, int parameters
2240 were changed to size_t.
2242 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2245 New MARC decode/display function, marc_display_exl, which properly rejects
2246 non-ISO2709 records. YAZ client uses it.
2248 --- 1.8.1 2001/10/29
2250 Fix bug: local attribute set wasn't set correctly in PQF strings.
2254 * Old Z39.50 codecs no longer supported.
2256 Added ZOOM C binding. See http://zoom.z3950.org/
2258 Renamed states for COMSTACKs to avoid confusion with events.
2260 Implemented cs_look and proper cs_rcvconnect.
2262 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2264 Configure detects POSIX threads on OpenBSD.
2266 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2267 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2269 When error is returned from present handler, non-surrogate diagnostic
2270 is returned in present response (and fetch handler is no longer called).
2272 * Minor adjustments to pquery parser (PQF). Token characters may be
2273 escaped by using backslash (C-style).
2275 PQF parser allows string attribute values to be specified. For @attr,
2276 non-numeric characters after the equal-sign are treated as strings
2277 (e.g. @attr 9=title).
2279 CCL trunction character may be defined (@truncation in file)
2281 * function zget_ExtendedServicesRequest sets waitAction to
2282 waitIfPossible (was wait).
2284 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2287 CCL operator names may be set in field definition files (CCL_bibset).
2288 See ccl/bib1 for an example.
2290 Fixes in ASN.1 compiler for C++ compatibility.
2292 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2293 and "op_or" to avoid conflict with C++.
2295 Fixed problem with GNU readline detection on Redhat 7.0.
2297 Added step-size for Scan backend handler.
2299 Fixed bug that made the frontend server crash when no attribute
2300 set was specified for scan.
2302 Front-end server automatically switches to original working directory
2303 when installed as an NT service. Previously -w had to be specified to
2306 Added extended attributes for retrieval module (data1), so that data1
2307 records carry d1_readXML/SGML attributes. d1_read also supports
2308 null-data rules ( <tag/>)
2310 On UNIX when POSIX threads are available, a separate library libyazthread
2311 is created. Programmers should link with that library and the yaz library
2312 when using threads. The reason for the split was that some applications
2313 on Linux, such as Apache, doesn't work well when using shared objects that
2316 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2317 (or any frontend server) in SSL mode by specifying ssl: followed by
2318 address. Only tested on UNIX.
2320 Added feature for CCL module. Virtual structure s=al or s=ol generates
2321 and-list and or-list respectively instead of phrase search.
2325 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2326 log_mask_str. This was done to avoid name conflicts with other libraries
2327 (such as other PHP extensions).
2329 Added raw OID member for preferred record syntax (request_format_raw)
2330 and returned record syntax (output_format_raw) for backend fetch method.
2332 Config file yaz-config now accepts options so that it returns specific
2333 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2335 Shared library support for UNIX using GNU libtool.
2337 * Modified backend interface. Request/Response struct's replaced by
2338 one read/write C struct. For example bend_fetchrequest and
2339 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2340 Every handler - even search has to be registered in bend_init
2341 handler. This means that the YAZ library no longer refers to
2342 external functions and it makes it possible to make the whole
2343 thing a single DLL/SO.
2345 Added Segment handler for backend server.
2347 Added Zmbol/Zebra administrative functions to YAZ client.
2349 Threaded frontend server on UNIX (when POSIX Threads are available).
2350 Starting the server with option -T enables multi-threading.
2354 Added configure option --enable-comp/disable-comp to control use
2355 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2356 located in sub directory asn.
2358 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2359 in ${exec_prefix}/bin along with the other programs yaz-client and
2362 GNU automake used to maintain makefiles.
2364 Added several OID's.
2366 Changed retrieval module so that we can load records with no abstract
2367 syntax defined. Tagpaths in these records are fully composed of string
2370 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2374 On UNIX, the generated makefile now supports a proper 'make install'.
2375 The prefix can be set via GNU configure to set the install location
2376 (default is /usr/local).
2378 * YAZ programs client and ztest were renamed to yaz-client and
2379 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2380 locations, such as /usr/bin,/usr/local/bin,etc.
2382 * YAZ Header files were moved from include to include/yaz. YAZ Header
2383 files are referred to as include <yaz/log.h> rather than <log.h>.
2384 The YAZ include path (-I ..) is therefore the same as before. Programmers
2385 should update their #include statements or use -Ipath/include/yaz
2386 instead. The main motivation for doing this change is that YAZ header files
2387 can be installed in "standard" locations /usr/include,/usr/local/include
2388 without introducing conflicts, since ALL YAZ header files are stored
2389 in subdirectory yaz (under /usr/include for example).
2391 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2392 rather than project/workspace files. We switched because project files
2393 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2396 Changed name of logging function, logf, to yaz_log, to prevent name
2397 clash with some math-log functions. The YAZ header log.h defines logf
2398 to yaz_log (#define) so there should be no incompatibilities by this
2401 Added bend_start/bend_stop handlers for server. These handler are
2402 called on start/stop of server. For windows they are called whenever
2403 a service is started/stopped.
2405 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2406 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2407 in util/yc.tcl. The auto-generated C code structures are, in a few
2408 cases, incompatible with the old decoders. There are differences in the
2409 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2410 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2411 The preprocessor variable ASN_COMPILED is defined when the compiled
2412 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2413 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2414 wish to use the old encoders/decoders you can specify --disable-yc
2417 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2418 version so that it supports both new - and old version of DB Update
2420 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2421 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2422 change. The name parameter can be set to 0 in which no name is specified
2423 for the construction. The macros odr_implicit and odr_explicit sets name
2424 parameter to zero for the construction involved. New macros
2425 odr_implicit_tag and odr_explicit_tag are similar to the others,
2426 except that a name parameter is added. For programmers' that don't use
2427 ODR they probably only need to change the call to z_APDU and z_External.
2429 Added access control facility by interfacing the TCP wrapper library.
2430 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2431 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2432 name of the daemon and enables the access control as specified in
2433 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2435 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2436 den Dool <H.M.vdnDool@kub.nl>.
2438 Added reference ID parameter to most functions in server API - refer
2439 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2441 Changed name of ccl library to libccl.a (was ccl.a).
2443 Fixed bug in decoder for Explain (Category TargetInfo).
2445 Added support for GNU readline in client. Thanks to Jacob Poulsen
2446 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2448 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2449 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2450 IMPLEMENTATION! This change was made to the development version before
2451 the ZIG decided to retract the amendment. If any users MUST be
2452 compatible with the original Update definition, PLEASE CONTACT US, and
2453 we will include a separate definition corresponding to the old Update
2454 ES. Note that because of the change to the ASN.1 of the
2455 TaskPackageRecordStructure we cannot define a single structure that
2456 will support both versions.
2458 * Added const modifier to buffer parameter for some ODR/BER encoding
2459 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2460 completeWAIS, odr_dumpBER.
2462 Fixed bug in client.c which caused a crash when a scanResponse didn't
2463 contain positionOfTerm.
2465 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2466 * will cause an error in a client if a non-YAZ target sends both a
2467 * list of Scan entries and non-surrogate diagnostics.
2469 Retrieval module enhancements. Tag sets may be typed in the reference
2470 to it. From the .abs-file the "tagset" directive takes a third optional
2471 integer type for the tag set referenced. From a .tag-file the "include"
2472 directive takes a third optional type as well. The old "type" directive
2473 in the tag set itself is still recognized but acts as the default type
2476 Backend interface change. Individual Scan terms returned from bend_scan
2477 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2478 in include/backend.h.
2480 Retrieval module enhancements. Multiple tag sets and attribute sets may
2481 be specified in abstract syntax specs. Revised the error/warning for
2482 logging messages reported by the retrieval module when reading the
2485 Object Identifier system (oid_..) changed. The API is backwards
2486 compatible but the oid-routines now allocates new OID's when needed.
2487 Raw OID's may be specified in oid_getvalbyname.
2489 YAZ now uses GNU configure to generate Makefile(s).
2491 * Minor changes in some of the member names of DeleteResultSetRequest and
2492 DeleteResultSetResponse. See include/proto.h.
2494 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2495 and added member 'languages' in TargetInfo (which was missing).
2497 Changed the way attribute sets are handled in the retrieval
2498 module. These are now cached, just like the abstract syntaxes
2501 Changed YAZ so that it links with compiled ASN.1.
2503 Added Explain-schema definitions and mapping routines. The following
2504 Explain categories have been implemented: AttributeDetails,
2505 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2507 Fixed minor bug in Windows version of Server Library.
2509 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2511 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2513 Added EXTERNAL: UNIverse Resource Report (non-standard).
2515 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2516 ENUMERATED and SET OF.
2518 * Added 'const' to some of the char pointer arguments for the
2519 functions, data1_read_node, data1_getelementbytagname,
2520 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2523 Fixed bug in data1_insert_taggeddata - the last_child member of
2524 parent wasn't initialised.
2526 * Changed data1_read_record and data1_read_node so that the supplied
2527 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2528 doesn't refer to any parts of the "SGML"-buffer.
2530 Fixed bug in server library (Windows version of statserv_remove).
2532 * Changed code so that it compiles as C++. The type definition
2533 of Odr_fun which is a member of Odr_arm was changed. The result is,
2534 that an explicit typecast is needed for the fun pointer when
2535 using Odr_arm - as in:
2536 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2538 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2540 Implemented the new structured date and time definition as approved
2541 by the ZIG. Added schemaId element to the specificTag in Espec-1
2542 (also approved at the last ZIG). Thanks to RVDM.
2544 Added some Object identifiers (RVDM).
2546 Changed the Update Extended Service (RVDM).
2548 Added command "refid" to client which specifies referenceId for
2549 the following requests.
2551 Implemented extended service handling for server. See ztest.c
2552 for an example as well as backend.h. New handlers are registerd
2553 in the Init handler.
2555 * Changed interface for sort in server.
2557 Added new members to statserv_options_block. It allows a server
2558 to read options from another source than just the command line. Thanks
2559 to Charles Woodfield.
2561 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2562 renamed to zboolean. Some C++ compilers complained about the name.
2564 Minor changes to gils.abs. Added index 's' (sort) on title
2565 and date/time-last-modified.
2567 --- 1.4pl2 1998/1/30
2569 Fixed bug in server library regarding inetd mode (-i). This bug
2570 was introduced by release 1.4.
2572 --- 1.4pl1 1998/1/29
2574 Added sort facility in client and backend server interface.
2576 Fixed problem with dependencies in Makefile(s).
2578 Fixed bugs for encoders/decoders of extended services and
2581 Implemented sub-tree feature for schemas. Sub-trees are
2582 referenced in *.abs-files. See explain.abs for an example
2583 of the use of this feature.
2585 Modified bib1.att; local attributes for ANY didn't include
2586 ANY itself (only affects use of the retrieval module).
2588 Fixed bug in plain SGML reader in function data1_read_node:
2589 tags with prefix "var" was incorrectly interpreted as variants.
2591 Added feature "sub-schemas" to enable references to - and definitions
2592 of - group of elements.
2594 * Removed member parent from type data1_element (in data1.h).
2596 Implemented function odr_nullval() that returns the value of
2599 * Removed member num_children from data1_node (in data1.h).
2601 Made NT service interface part of the server library. The
2602 function statserv_main uses the NT service when required and
2603 calls the statserv_start / statserv_close routines.
2605 Routine zget_SearchRequest and zget_PresentRequest fills
2606 resultSetName/Id member with "default" instead of "Default".
2608 Fixed memory leak in server. Request queue member wasn't freed.
2610 Fixed nmem_exit so that memory is freed.
2614 Revised the CCL parser utility to be thread safe.
2616 Added function, oid_ent_to_oid, to replace the function
2617 oid_getoidbyent, which is not thread safe.
2619 * Added nmem_init and nmem_exit to initialize and release
2620 NMEM resources. Function nmem_init should be called once in the
2621 initial thread before NMEM/ODR is used. statserv.c and client.c
2622 have been changed accordingly. The change was necessary to make
2623 NMEM thread safe. The NMEM memory pool is shared amongst threads
2624 in a process. Unix-based applications will still work fine without
2627 Added NT Services interface for the the Z39.50 (statserv) Server.
2628 Refer to the ztest.c source on the usage.
2630 Windows 95/NT port using MSVC5.0. Project files are included in the
2633 * Defined new 'global' handle for the retrieval (data1) system. The
2634 new handled, data1_handle, describes the state of the data1 system.
2635 This handle is passed as first argument to virtually all
2636 data1 related routines. The functions data1_create and data1_destroy
2637 creates and destroys a data1 handle respectively.
2639 Added ODR encode stream member to all backend request structures
2640 init, search, scan etc. This stream should be used to allocate all
2641 memory used for the response when thread safe operation is needed.
2643 Changed the comstack utility, cs_addstr, to be thread safe. The
2644 returned hostname string returned by the function is now part the
2647 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2648 function. The cs_straddr takes a COMSTACK handle as argument, so this
2649 function must be used after cs_create and before bind/connect.
2650 This function is thread safe.
2652 Moved test server to 'ztest' directory - generic server code still
2653 in 'server' directory.
2655 Made prefix query (pquery.c) utility thread safe.
2657 Added new function modifier YAZ_EXPORT to 'export' public DLL
2658 functions when using windows (see include/yconfig.h).
2660 Added definitions to the OID database (util/oid.c) (RVDM).
2662 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2664 Added call to ccl_rpn_delete in client program.
2666 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2667 release of RPN structure.
2669 Added support for C++, headers uses extern "C" for public definitions.
2670 With input from RVDM.
2672 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2673 Thanks to Ronald van der Meer (RVDM).
2675 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2677 Added support for private extensions to the OID database
2678 (oid_setprivateoids()). Thanks to RVDM.
2680 Added optional, physical ANY (key replication)
2682 Fixed null-reference problem in GRS-1 output filter.
2684 Proximity operator added to Prefix Query Format (PQF).
2686 In test client command "base" accepts multiple databases.
2688 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2692 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2694 Smallish bug-fixes in the new encoders/decoders (explain).
2696 Bug fixed in DeleteRequest.
2698 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2700 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2702 Added SOIF syntax (using private OID for now) to retrieval module and client.
2704 Added Update extended service.
2706 Added SearchResult-1 additional info structure.
2708 Added optional CCL (ISO8777) interpreter as separate module. Available
2711 --- 1.2 1996/6/10 (1st anniversary release)
2713 Added Summary record syntax. Lightly tested.
2715 Added OPAC record syntax. Untested.
2717 Added ResourceReport service encoders/decoders. Untested.
2719 Fixed bug in z_Unit - wrong tagging on unitSystem.
2721 Fixed bug in the DiagRecs decoder.
2723 Added options for max PDU size and session timeout to frontend-server.
2725 Added documentation of query-language parsers and other supporting utilities.
2727 [frontend-server] Added Attribute set to the bend_scanrequest API.
2729 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2730 surrogate diagnostics were generated.
2732 [retrieval] Allow multiple local values for attribute.
2734 [retrieval] Allow multiple attributes per element in .abs files. index type.
2736 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2738 --- 1.1pl2 1996/4/10
2740 Minor changes, mostly specific to Zebra's requirements (retrieval)
2744 Repaired bug in frontend server when running multiple listening
2745 endpoints in dynamic mode.
2747 z_External() now won't break if a known, ASN.1 value comes encapsulated
2748 in an octet-string. The value will pass through unmodified in an Odr_oct.
2750 Added a bit of code to the demo client to decode & display
2751 ASN.1-structured records represented in the octet-aligned branch of
2752 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2754 Added z_ext_getentbyref() to the ASN module. Doc updated.
2756 * Completed the SCAN definition in the ASN module. This may break SCAN
2757 code based on older YAZ-versions at compile-time. The fix is easy -
2760 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2761 under the SCAN definition. Remember to initialize this, server-people.
2763 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2764 that this does not extend to ODR and ASN.
2766 Comstack allows insertion of established socket (primarily for
2767 inetd-operation of servers). Doc updated.
2769 Front-end server can now start from the inetd in TCP mode. Doc
2772 --- 1.0pl4 1996/1/24
2776 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2777 the rank and record number.
2779 Adjustments to the frontend server.
2781 Fixed diagnostic BER dumper. It ignored the file argument.
2785 Various changes to retrieval module.
2787 Changed the union discriminators of the protocol files from enums to
2788 ints paired with #defines.
2790 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2793 *Changed operator in the RPN structure to 'roperator', again to avoid a
2796 Fixed problems in Explain decoders/encoders.
2798 --- 1.0pl2 1995/12/6
2800 Memory bug in log module fixed.
2802 --- 1.0pl1 1995/12/5
2804 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2806 Bug in Explain DatabaseInfo module fixed.
2808 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2812 The shift to v1.0 signals that we now consider the *core* functionality
2813 of YAZ reasonably stable (the core being more or less equivalent to
2814 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2815 tested (Explain not at all - though that will happen soonish).
2817 Minor changes to code to support Windows port.
2819 Various minor changes after we're getting to use GRS-1 & co. more.
2821 Added Espec-1 format.
2823 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2824 of the protocol and it cannot be selected when encoding (maps into 'string'
2825 when decoding). Needed to talk to some servers.
2827 Demo client can request simple element set names.
2829 Added Diagnostic Format encoders/decoders.
2831 Added simple Close handling to frontend server (no hooks for resource
2832 reporting yet), and demonstration client.
2834 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2836 --- 1.0b3 1995/08/24
2838 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2839 handled incorrectly when records were requested in the searchResponse. This
2840 will only affect you if you use the frontend-server.
2842 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2843 Test-client will ask for and print GRS1. Ztest will return dummy records
2846 Added Explain encoders/decoders to the service-level API. Untested.
2848 Added Extended Services: Item Order encoders and decoders to the Service-
2849 level API. Untested. We could use a recent copy of the pertinent bits
2850 of the ILL protocol to add those bits.
2852 Added diagnostic format 1 encoders/decoders to the service-level API.
2855 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2856 odr_cons.c, which causes a more correct output.
2858 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2859 was always set to 0 when no records were requested in the searchRequest.
2861 * Added better external-handling. This shouldn't harm old code that
2862 *encodes* externals. It can break code that looks for a
2863 'single-ASN1-type' representation, since those types that are known
2864 are now decoded immediately. Look at the SUTRS sample code in
2865 seshigh.c and client.c. Documentation updated.
2867 Handling of structured records in bend_fetchresponse. Length -1 marks
2868 structured record, type is deduced from format field.
2870 --- 1.0b2 1995/06/27
2871 Fairly quick maintenance release to add SUTRS support.
2873 Fixed handling of SUTRS records in the demonstration client.
2875 * Added format field to the bend_fetchrequest and bend_fetchresponce
2876 structures of the backend API (frontend server). When the record is
2877 returned, the value of the format field is mapped to an OID. The
2878 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2879 of the record. The special value VAL_NONE in the bend_request means
2880 that no specific format was requested by the client. Documentation
2881 updated accordingly. Test server (ztest) will return a fixed dummy
2882 SUTRS record if your client requests SUTRS.
2884 Documentation updated accordingly.
2886 You can now set external libraries and RANLIB support in the top-level
2890 First public release.
