3 yaz-client: show may XML format records. Command show followed by 'format'
4 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
7 src/stemmer.c: Avoid using unnamed union. It is not supported by some
10 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
13 Update yaz.spec to operate on both SLES11 / Centos 5.5.
15 RPM: Release includes 'indexdata' name. Use indexdata in release name so
16 this package can be distinguished from other vendors.
18 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
19 as determined by configure
21 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
23 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
24 returns no error and no record, the present request is considered
25 partial (only a subset of the records could be returned by backend), and
26 so it is appropriate to set Present Status to partial-4.
30 Move yaz-config man pages to section 1.
32 More documentation about SOLR.
34 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
35 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
36 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
37 peers on some Linux systems. However, in general that does not work
38 so YAZ can not rely on that to work. Debian changed behavior in this
39 respect from Debian lenny to Debian squeeze (still testing as of Oct
41 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
43 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
47 Fix yaz-config output: echo_source not set correctly by configure.
51 SOLR WebService support for yaz-client and ZOOM.
53 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
57 Z39.50 facet support. Facet specifications are passed for search in
58 other-information with ASN.1 as defined in facet.asn and OID
59 .10.1000.81.5 . Facets are expressed as an Attribute list as known
60 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
61 3 is limit (number of entries to get in response). yaz-ztest returns
62 dummy facets if a client asks for them.
66 CCL fixes: bug 2895 and bug 3539.
68 GR1-display: add comma in display - was removed by mistake in
71 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
73 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
77 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
78 result set from a connection. The result set will be on its own
79 thereafter; no operations on it will perform retrievals from a target.
80 Only cached copies are returned.
82 ZOOM C:fix case for HTTP servers responding with Connection:close.
83 Ensure that if there is a current task it is resumed (like fetching
84 more records in a result set) . Bug #3484.
86 PQF parser: use odr_atoi for Odr_int (not atoi)
88 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
89 values that contain any non-digits are treated as string attributes
90 (previously decoding only checked for leading character ([0-9]). PQF
91 encoding: attribute string values are not surrounded by double-quotes.
95 New utility for managing threads - thread_create.h.
97 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
98 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
99 but YAZ' implementation do.
101 Fixes for yaz_cond-functions on Windows 7.
103 DLL export more symbols.
105 zoomsh: show record do NOT render opac.
107 Remove *.la files from Debian and RPM packages.
111 Debian package libyaz-dev depends on libgnutls-dev again (was
112 removed in YAZ 4.0.6, but due to Libtool it is still needed
113 even though yaz-config do not list libgnutls libs).
115 ZOOM: Use only one WRBUF for returning string results for
116 ZOOM_resultset. Reduces memory usage for ZOOM in general.
118 ZOOM: ZOOM_connection do not use a shared pointer to
119 ZOOM_resultset after ZOOM_resultset is destructed by
120 user. Reverts to YAZ 4.0.4 behavior.
124 record-conv: fix problem with at least one XSL conversion -
125 due to probably incorrect usage of XML XSL documents.
129 Fix yaz-config for static mode and the use of SSL (gnutls).
133 Forward decl timeval struct in mutex.h and gettimeofday.h.
135 yaz-config: fix 'static' mode linking.
139 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
140 are wrappers for pthreads or Windows. For Windows these are put in
141 a separate DLL: yaz_cond4.
143 libyaz.la (whole source) is compiled with thread. If thread support
144 is enabled enabled, all source of YAZ is compiled with treading support.
145 This allows core utilities such as yaz_log to use thread facilities.
146 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
147 thread utilities. This commit moves mutex utilities (mutex.c) from
148 libyaz_server.la to libyaz.la.
150 yaz-json-parse displays leading text until error.
154 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
155 patch from Giannis Kosmas.
157 SRU: no longer URL encode SRU database. The URL for an SRU server is
158 a URL and such is alreeady encoded - at least when given with leading
159 http:// or https://. This reverts behavior to YAZ 3.0.50.
161 Support for new MARC XML notation TurboMARC which like MARCXML is a
162 complete representation of MARC/ISO2709.. This one, however, is more
163 compact and allows for faster processing with XSLT. TurboMARC can be
164 used in the marcdisp.h API, from the yaz-marcdump utility and from
167 yaz-ztest can be configured - via the database - to perform certain
168 delays when it performs operations search, present and single record
169 fetch. This allows testers to make yaz-ztest act as a real or even slow
170 Z39.50 server. Refer to the yaz-ztest man pages for details.
174 wrbuf_destroy allows NULL WRBUF passed to it.
176 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
178 Add ZOOM_connection_close.
180 No fixed size buffers for ZOOM shell - bug #3257.
182 tstodr: make it work on s390 platform.
184 New icu iterator-functions. The new icu_iter-functions makes it possible
185 to use ICU chains from many threads.
187 yaz-client: better syntax check for show command.
191 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
194 New simple local-file XML include facility which allows file glob-patterns.
195 Refer to yaz/xml_include.h.
197 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
200 ZOOM_record_get supports new parameter "format" which makes it format XML
203 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
204 JSONText in ECMA-262) is JSONValue, not JSONObject.
208 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
209 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
211 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
212 POSIX/Unix builds .so with major version 4.
214 Remove old LOG_-defines from log.h. They have been obsolete and
215 undefined by default for the last 5 years.
217 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
219 GFS: Remove socket (int *fd) from search_rr handler. The socket
220 descriptor ptr is a facility that allowed a search handler to supply
221 a socket which would serve as a callback - when search was complete.
222 This facility has now been in use for years.
224 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
225 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
226 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
227 returns 'const char *' rather than 'char *. The returned string is
228 read-only and should not be modified by applications. COMSTACK cs_close is
229 now a void function - it no longer returns int. No applications check for
230 the value and the implementations has always returned 0.
232 ZOOM: use size_t for scan hit counts and str size. Functions
233 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
234 occ (hit count) and len (string length) are now of type size_t pointer
235 rather than int pointer. This is to be able to represent large hit counts
236 and to also just to use the proper type for string length (strlen result).
238 New JSON parser. Refer to include/yaz/json.h .
240 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
241 Used to be int in some cases. Many wrbuf_-functions used to return an int
242 indicating some length.. These return values were never used. And so they
245 ODR: odr_malloc, odr_total now takes size_t for size.
247 clone_z_type: fix leak; occurred for encoding failures.
249 --- 3.0.52 2009/12/03
251 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
252 bug was introduced in 3.0.51.
254 --- 3.0.51 2009/12/02
256 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
258 tcpip comstack: fix leak for getaddrinfo.
260 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
261 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
262 Decoding of SRU "path" database is performed by private function
263 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
264 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
266 yaz-client: honor base command for SRU. Change when database setting
267 is applied for SRU and ensure it is kept when a connection is reset.
268 Change also the way errors are displayed or SRU (decoding of packages).
270 --- 3.0.50 2009/11/02
272 Add support for extra request / response data for SRU codecs and GFS.
273 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
274 for extra data response buffer and length. For the GFS, both request
275 and response data (XML) is carried in extra_args and extra_response_data
276 for the search handler. Patch by Ko van der Sloot.
278 ZOOM: For queries that cannot be converted to the specified rpnCharset,
279 ZOOM now returns a diagnostic on the client-side ('invalid query' /
280 10010). This fixes bug #2113.
282 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
283 cmdfile included a 'quit' command that would result in a memory violation.
285 --- 3.0.49 2009/10/01
287 Make a number of functions defined in xmlquery.c static. These have
288 never been declared in a public header file (yaz/xmlquery.h) and was
289 made public by mistake.
291 Improve speed of character conversions (iconv utilities). This makes
292 conversions from MARC-8 faster.
294 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
295 unless type desired is "raw". This will prevent type "xml" from
296 returning ISO2709 .. Which obviously can not be XML parsed.
298 Fix memory leak in ZOOM that would occur if option apdulog was used
299 on a re-used connection.
301 Frontend server logs HTTP requests.
303 Frontend server now sends Z39.50 close when it times out (sesssion has
304 been idle for too long). Versions 2.0.30 and earlier also sent close.
305 But due to a mistake this was disabled in all versions after that, i.e.
306 the server would just close the socket immediately.
308 yaz-client emits a better message when receiving an unrecognised
309 userInformationField.
311 Skip zero-length subfields when decoding ISO2709. This rare case happens
312 if a record has two FS characters in a sequence. Without this patch
313 there would be a reference beyond char array in using_code_len fragments
316 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
318 --- 3.0.48 2009/08/28
320 The show command offered by the zoomsh command now takes a 3d optional
321 parameter type which is what is passed to ZOOM_record. If the type
322 argument is omitted, "render" is used.
324 RPN to CQL conv may use USE string attributes (bug #2978).
326 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
328 --- 3.0.47 2009/07/08
330 Function yaz_xml2query allows a diagnostic element in the PQF XML
331 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
332 code and additional info respectively.
334 The BER BOOLEAN is now the integral type Odr_bool which still happens
335 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
336 typedef'd to Odr_int. This is still an integral 'int', but it may be
337 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
338 ASN-1 compiler as well as programs has been updated to use the new types.
340 --- 3.0.46 2009/06/08
342 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
343 only the bibliographic record was rendered. For type=opac, an OPAC
344 record is only returned if it is present.
346 iconv: small fix for encoding of advancegreek.
348 yaz-client: avoid double display of SRU/SRW records (bug #2798).
350 yaz-client: option auto_reconnect=on really reconnects.
352 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
354 server: avoid null ptr ref for for yaz_poll errors.
356 build: fix RPM build for RHEL 5.3.
358 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
360 --- 3.0.45 2009/03/31
362 Fixed bug #2709: TCP connect returns Invalid argument.
364 Fixed compilation for mingw.
366 Honor charset for raw records (ZOOM_record_get).
368 Fixed use of errno for threaded mode that was seen on Solaris 10.
370 Fixed argument passing with blanks in value for Windows Service.
372 Disable YAZ' own log rotate by default (no 1 GB limit).
373 The variable l_max_size which specifies the log file limit is set to 0
374 (DISABLED): This is due to the fact that YAZ is most often deployed using
375 logrotate. Also YAZ can not perform log rotate because of unsufficient
376 permissions (setuid).
378 --- 3.0.44 2009/02/17
380 List supported encodings in man page for yaz-iconv.
382 Fixed missing SSL libs for --libs output
384 Re-established OID record syntax application-xml. Nobody should use it
385 but we don't want to change soname because of this symbol being absent.
387 --- 3.0.42 2009/02/02
389 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
391 Added member named_result_sets for init handler struct for the GFS. This
392 allows a server to disable named result sets.
394 Removed OID record syntax application-xml.
396 Added support for rule-based transliterator for ICU wrapper of YAZ.
398 Fixed bug #1902: yaz-icu XML output.
400 Make YAZ checks Emacs friendly.
402 BITSTRING value shows value. Bug #2346.
404 ISO2709 decoding: skip control characters from indicator data.
406 Omit sort key by default in yaz-icu's output.
408 Allow combined single char options (again) for YAZ' options function.
410 Utility yaz-marcdump got option to display YAZ version (-V).
412 Allow YAZ to use ICU 3.4.
414 Added new ICU test case which illustrates removal of diacritics.
416 --- 3.0.41 2008/12/29
418 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
420 --- 3.0.40 2008/12/29
422 For configure, using option --without-xml2 also disables Libxslt/Libexslt
425 Fixed bug #2352: yaz-marcdump crashes for certain record.
427 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
429 Added support for Danmarc2 to UTF-8 conversion.
431 Added support for ISO5426 to UTF-8 conversion.
433 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
434 implementation version.
436 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
438 --- 3.0.38 2008/11/10
440 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
441 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
443 ZOOM C now interprets databaseName option for ZOOM connection as path
446 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
448 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
450 Dummy Libxml2 types no longer defined in headers of YAZ'.
452 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
455 --- 3.0.36 2008/09/26
457 Various ODR chapter fixes.
459 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
461 Added missing source for Windows compilation, mutex.c.
463 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
465 For SRU connections in ZOOM all records up to "count" are now fetched.
467 Fixed crash in generic frontend server (and yaz-ztest) which occurred
468 in Windows due to bad error handling for Libxml2.
470 Added facility for sending arbitrary records (ASN.1 any) using
471 ZOOM C's Extended service update. Patch by Sam Reynolds.
473 New options for ZOOM C's connection, logapdu which makes ZOOM log
476 --- 3.0.34 2008/06/18
478 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
480 --- 3.0.32 2008/06/12
482 Fixed memory violation that could occur when decoding UTF-8. This bug
483 was only present in 3.0.30 of YAZ.
485 --- 3.0.30 2008/06/06
487 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
488 GNU TLS is used by default (if found).
490 yaz-ztest returns OPAC records if a client asks for OPAC.
492 Improved speed of MARC-8 encoding.
494 Added support for lossy and loss-less MARC-8 encoding.
496 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
498 Added new Windows Service wrapper (sc).
500 yaz-client's itemorder command may now send a file.
502 Fixed yaz-marcdump to allow the use of NS prefix for record element.
504 Added new function yaz_log_xml_errors.
506 Allow (but warn) unknown XML attributes in MARCXML parsing.
508 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
510 The UTF-8 to MARC-8 conversion now uses a different set of characters
511 for Greek symbols. Bug #2120.
513 --- 3.0.26 2008/02/21
515 Added yaz_daemon (daemon.h).
517 Fixed bug #2068: pkg-config trouble
519 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
521 --- 3.0.24 2008/01/28
523 Document --with-xml2 option.
525 Added OPAC XML XSD (etc/opacxml.xsd).
527 Allow glob mask for name attribute in retrieval element for the
528 generic frontend server's retrieval facility.
530 Changed yaz_poll_poll to return yaz_poll_except for all returned events
531 except POLLIN/POLLOUT.
533 Fixed error handling in cs_listen. Bug #2037.
535 --- 3.0.22 2008/01/20
537 Fixed version in yaz/yaz-version.h.
539 Fixed bug #2027: Crash when closing connection.
541 Changed configure so that ICU support is only enabled if only ICU
542 and Libxml2 is available (because the ICU chain is XML based).
544 --- 3.0.20 2008/01/15
546 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
547 is built. Only this DLL depends on the ICU runtime.
549 yaz-ziffy is no longer part of YAZ. It is distributed separately by
550 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
552 Changed license of CCL module to 'Revised BSD'. After consultation with
553 remaining members of the original EUROPAGATE consortium, we are re-issuing
554 the CCL module without a separate license. The software was developed by
555 Index Data as part of a research project. The special license was included
556 to help feed usage information back to the project consortium to support
557 project evaluation. At this time, the project consortium has long-since
558 disbanded, and the majority of the original principals have retired. At the
559 same time, we have significantly modified the software during the following
560 years, to the point where very practically no original code remains. To
561 simplify re-use of the software, we have contacted those members of the
562 consortium who could be reached, and agreed to re-issue the module as a
563 proper part of the YAZ package.
565 Tcl scripts uses /usr/bin/tclsh as preferred shell.
567 CQL closer to being version 1.2 compliant. CQL also allows free-form
568 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
571 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
572 bug could make Extended services handling crash in the ZOOM layer. This
573 bug was only present in YAZ 3.0.18.
575 --- 3.0.18 2007/12/19
577 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
580 yaz-marcdump reads and writes collection wrapped records.
582 Handle OPAC for record conversion module.
584 Fixes for ICU wrapper.
586 Allow ICU libs to be controlled with --with-icu .
588 --- 3.0.16 2007/11/12
590 Added yaz_poll which is a wrapper for select/poll. When poll is available
591 and non-buggy, it is used, by yaz_poll . This allows more than 1024
592 sockets to be in use.
594 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
595 functionality through an XML based configuration (ICU chain). This system
596 is useful for search facilities such as Pazpar2 and Zebra that needs to
597 perform tokenization of indexed material. The ICU code in a separate
598 library libyaz3_icu.a.
600 Added HTTP tunnel facility for COMSTACK, bug #1752.
601 This is a facility that allows a Web proxy, such as squid, to tunnel
602 Z39.50 traffic. This facility is "transparent" to must applications
603 using YAZ. It's enabled by using pseudo transport connect: followed by
604 the proxy address, followed by command, then follwed by he regular
605 "virtual" addresss. For example,
606 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
608 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
610 --- 3.0.14 2007/09/21
612 Fixed bad memory reference in ZOOM_record - cuased by member not being
613 initialized. This was a problem only in YAZ 3.0.12.
615 Fixed bug in conversion from MARC to XML: Non-XML characters in control
616 fields were not removed.
618 Changed the way C code is generated from codetables.xml. Made a MARC-8
619 conversion trie for each characterSet section rather than codeTable.
620 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
621 of codetables.xml from Larry Dixson, LOC. Bug #1464.
623 --- 3.0.12 2007/09/12
625 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
626 from ZOOM_record_error).
628 ZOOM C function ZOOM_record_get returns record schema for type="schema".
630 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
632 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
634 Better SRW-to-Bib-1 diagnostic mapping.
636 ZOOM C and yaz-client announces SRU version 1.2 by default.
638 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
641 Fixed in yaz_sru_decode to allow other version than 1.1.
643 --- 3.0.10 2007/08/22
645 Added support for SRU scan for ZOOM.
647 Added support for the use of the older versions or Extended Service
648 Update in ZOOM. To faciliate this, an option "updateVersion" may be
649 set to the version , 1=first, 2=second, 3=third. The third version is
650 what ZOOM C has used so far. And that, obviously, is the default.
652 Added support for CCL queries in Z39.50 queries sent to the GFS (and
653 therefore in Zebra and in SimpleServer-based applications). The new
654 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
655 qualifier file used to transform incoming CCL queries into Type-1 RPN,
656 which is passed into the back-end search callback function.
658 Added support for HTTP Basic authentication in clients: the SRU/W
659 codec encodes the username/password elements of the PDU structure
660 appropriately, and these may be set using the "user" and "password"
661 options in ZOOM-C applications (the same options that are used for
662 Z39.50 authentication).
666 Fixed bug #1208: SSL appears to be broken in ZOOM.
668 Fixed bug #1206: Libxml2 include path weirdness.
670 Added oid_name_to_dotstring.
672 Allow elementSetName to be specified for ZOOM C record update.
674 Allow waitAction to be specified for ZOOM C based for Extended Services.
676 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
677 syntax OID. Bug introduced in YAZ 3 series.
679 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
683 Fixed bug #1157: yaz-client does not read .yazclientrc from current
684 directory. yaz-client now reads commands from file given by option -f
685 if specified; then tries to read .yazclientrc in current directory.
686 Failing that, it reads .yazclientrc from user's home directory.
688 Added support for correlationInfo Note and ID for Record Update via
691 Added yaz-client command querycharset which specifies character set for
692 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
693 (termListAndStartPoint).
695 Charset ISO5428:1984 is an alias for ISO5428-1984.
697 Implemented a way to perform scan in a result set using Z39.50. This
698 is achieved by attaching the result set name in the characterInfo
699 (type InternationalString) of OtherInformation in the Scan Request PDU.
700 The result set is identified in the otherinformation by the new OID:
701 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
702 This allows for scan in result set and faceted search . Zebra did some
703 of this in the APT term using attribute type 8 and value being result
704 set. Using the OtherInformation approach for this is cleaner and easier
705 to work with in proxies and the like. This facility can be used in
706 yaz-client using new command setscan which takes a result set as first
707 argument, start position (APT) as second.
709 Changed decoding of SRU XML packed records to deal with servers that
710 have recordData with XML data with multiple root nodes. Also make
711 comparison for recordPacking case insensitive. Again, one server
712 returns "XML" where others return "xml".
714 For SRU responses allow Content-Type application/xml as well as text/xml.
718 Fixed bug in character set conversion of BER strings. Bug introduced
723 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
725 For OID class, use oid_class consistently.
727 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
730 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
731 character set for bibliographic information interchange". By Giannis Kosmas.
733 Added documentation on new OID API.
737 Changes to generic frontend server interface: added new member
738 'query_charset' for bend_initrequest structure. A backend init handler
739 should set this member to its native character set for query terms.
740 When defined, the frontend server logic will announce this character set
741 to a client if the negotiationModel bit is set by the client. All server
742 implementors are encouraged to specify this. If a backend server does not
743 specify this a warning is issued using yaz_log(YLOG_WARN,..).
745 Added CCL utility to remove terms (stop words) from resulting RPN
746 tree. This is handled by functions with prefix ccl_stop_words_ .
748 New ZOOM C option, "rpnCharset", which allows client-side conversion of
749 terms in RPN queries.
751 Clean-up the CCL API. Moved some internal structures from ccl.h to
752 private header cclp.h. Changed ccl_parser_create so that a Bibset must
753 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
754 This is replaced by ccl_parser_find_str which takes a string instead.
756 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
757 libyaz.la is the core of YAZ except the generic frontend server and
758 does not depend on POSIX threads anymore. libyaz_server.la is the
759 generic frontend server facilities and uses POSIX thread functionality
760 if available. The libyaz.la no longer depends on POSIX threads because
761 the number of global structures is limited. NMEM no longer re-uses blocks
762 between threads ; it simply free's memory immediately but allocates in
763 "large" chunks as usual. We don't expect any performance penalties
764 because of this. The yaz_log system is still using a global log_level so
765 caution must be taken when modifying it with yaz_log_init_.. +
766 yaz_log_mask_str. This, however, should not cause any trouble because
767 these functions are called during initialization of application code
768 anyway. `yaz-config --libs server` returns libs for server applications;
769 `yaz-config --libs` returns libs for non-server applications.
771 New OID database - with public definitions in oid_db.h. Removed old OID
772 database including the head oid.h and definitions such as enum oid_value
773 and struct oident. The new OID database uses the same string names as
774 before but the 'protocol' is gone. There are now only two representations
775 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
776 converts from string to OID; functions with prefix yaz_oid_to_string
777 converts the other way.
779 Change to emit_term() in CQL-to-PQF query translation: when a term has
780 the /regexp relation modifier, do not process it for leading and
781 trailing "^" and "*", which have quite different meanings in regular
784 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
785 write handlers no longer carries a 'last' parameter. This will make
786 yaz_iconv flush "less" characters. A flush is performed by call to
787 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
789 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
790 removed, because function yaz_query_to_wrbuf does the same.
792 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
793 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
795 Deprecated MARC utility functions removed.
797 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
800 Branch split: YAZ_2_1_55_branch
802 --- 2.1.54 2007/03/16
804 Fix to ZOOM-C so that transparent reconnection is properly handled on
805 connections that are in asynchronous mode.
807 Fixed compilation on OpenBSD 4.0.
809 Large strings in GRS-1 records are now properly displayed in yaz-client.
811 Added character conversion support for "advancegreek"; based on patch from
814 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
815 sequence is met. Before the error was not set so it would be unknown.
817 Adjust yaz-marcdump MARC reader so that it skips until record separator
820 --- 2.1.52 2007/03/07
822 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
823 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
824 fd_set structure used as a bitmask for the FDs to be selected on.
826 Using ACX_PTHREAD macro to check for POSIX threads.
828 Fixed have-vsnprintf check.
830 --- 2.1.50 2007/02/23
832 Fixes for configure on BSD. Bug #900.
834 Added snprintf/vsnprintf wrappers for systems that don't have
835 limits (heavens forbid).
837 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
838 created before all previous tasks were completed and removed from the
839 task queue, the new task could be removed by a mistake.
841 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
843 Implemented pass-through CQL-to-PQF conversions. Bug #861.
845 Fixed bug #832: Problem with MARC/charset in yaz-client.
847 Fixed bug #668: save command line history for yaz-client.
849 Fixed bug #830: pkg-config support.
851 --- 2.1.48 2007/01/23
853 Extended ZOOM result set options with two options that may be read by
854 a client: resultSetStatus and presentStatus with values as specified for
856 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
858 Fixed bug #827: Using SSL fails on Debian etch.
860 Fixed bug #826: Weird looking chars for set of MARC records.
862 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
863 that is treated as an ItemOrder with itemRequest being an XML document
864 external. The value of "doc" is the content.
866 Extended the GFS search facility. New member of bend_search_rr
867 'estimated_hit_count' signals that hits is known to be an estmate
868 (higher or lower than real hit count). New member 'partial_resultset'
869 signals that the search was partial (hit count is lower or equal than
870 real hit count). For Z39.50, the information is stored in resultSetStatus
871 member of SearchResponse APDU. For SRU, the information is signalled
872 via SRU diagnostic 59: "Result set created with valid partial results
875 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
877 --- 2.1.46 2007/01/13
879 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
881 Added ZOOM_connection_peek_event.
883 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
884 the following new functions:
885 ZOOM_event_nonblock, ZOOM_connection_process,
886 ZOOM_connection_get_{socket,mask,timeout},
887 ZOOM_connection_fire_event_{timeout,socket}.
888 The existing blocking event handler, ZOOM_event, is a wrapper for the
889 + blocking ZOOM_event_sys_{poll,select}.
891 Implemented function ccl_xml_config which parses XML version of CCL
892 configuration (bug #798).
894 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
896 Added timings utility (yaz/timing.h)
898 --- 2.1.44 2007/01/03
900 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
903 Fixed bug #779: Rotation of apdu.log fails.
905 Fixed for character set conversions:
906 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
907 Honor G1 set in MARC-8 decoding.
909 --- 2.1.42 2006/12/17
911 Fixed bug #775: char conversion does not handle Alternative UTF-8
914 Implemented function yaz_marc_read_line which parses MARC line format
915 records. There is a wealth of formats out there. So far, this function
916 reads line records produced by yaz_marc_write_line.
918 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
919 more generic and easier to remember(!) options: -i format and -o format
920 which specifies input format and output format respectively - where
921 format is one of "marc", "marcxml", "line", "marcxchange".
923 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
924 does not print anything except warnings for records.
926 For yaz-marcdump, added support for MARC split into files (-s) with a given
929 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
930 spec, at http://www.loc.gov/standards/sru/record-update/
931 This has changed the binary layout of the following structs:
932 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
933 bend_update_rr . Patch by Ko van der Sloot.
935 Added GFS utility function bend_assoc_is_alive which returns 1 if
936 association is still alive (client is connected); 0 otherwise (client
937 closed connection). This allows busy servers to stop working for
940 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
941 been a separate piece of software. This version of ziffy has been modified
942 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
944 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
946 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
947 Client code may now interrogate options such as "init_opt_sort" to
948 find out whether the server claims to support various options.
950 --- 2.1.40 2006/11/27
952 Added utilities yaz_{set,get}_esn to set/get element set name from
955 Removed the build of libyazthread.la. The libyaz.so is the threaded version
956 of YAZ and has been so since YAZ 2.1.10.
958 Implemented ZOOM_record_error which returns error information for
959 record (surrogate diagnostic).
961 --- 2.1.38 2006/10/31
963 Updates for SRU Update by Ko van der Sloot:
964 1. Changed name from "operation" to "action"
965 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
966 versions in the code, marked as 'backward compatible'.
967 3. Added diagnostics for SRU Update.
969 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
971 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
973 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
975 For GFS, fixed problem with SRU diagnostic 'First record position out of
976 range' being issued for 0 hits.
978 zoomtst10 part of Windows Build.
980 --- 2.1.36 2006/10/13
982 Implemented yaz_filepath_comp which splits a path into file path
983 components (required by Zebra 2.0.3+).
985 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
986 BSD inspired license until now so this should not have any real impact on
987 anybody. See http://www.opensource.org/licenses/bsd-license.php
989 Fixed bug #687: Missing log lines.
991 Fixed bug #678: CQL to PQF translation does not preserve double-quote
994 Fixed bug #689: SRU diagnostics to be added.
996 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
997 whether a connection is idle (no more work do do).
999 --- 2.1.34 2006/10/04
1001 Change type of optval from long to int for invocation of setsockopt with
1002 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1004 Added support for specifying the max log file size for the Generic
1005 Frontend Server. The size is given with option -r.
1007 --- 2.1.32 2006/09/21
1009 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1011 --- 2.1.30 2006/09/17
1013 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1016 Fixed bug in Generic Frontend Server that could cause a server to stop
1017 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1019 For the generic frontend server, the maximum record size is used as maximum
1020 size of incoming packages (SRU + Z39.50). The value until was previously
1021 only used in Z39.50 Init negotiation and, later, in a session controlled
1022 sizes of records returned. This is controlled using -k option. It can be
1023 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1025 --- 2.1.28 2006/09/04
1027 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1030 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1032 New option for yaz-marcdump -lpos=value which allows setting a portion
1033 of MARC header to a certain value.
1035 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1037 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1038 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1040 --- 2.1.26 2006/08/15
1042 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1045 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1047 --- 2.1.24 2006/08/08
1049 Fixed MARC ISO2709 encoding routines to deal with character set
1052 Minor changes to GFS logging. Database included in search request log
1055 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1056 cached/multiple records.
1058 Shared libraries are built by default on Unix+configure.
1060 Changed cql2pqf transformation to use a different evaluation order. The
1061 new order is: always, relation, structure, position, truncation, index
1062 and relationModifier. Old order was: always, relation, relationModifier,
1063 structure, index, position, truncation. Note that the the latter ones
1064 override former ones for identical attributes.. The new scheme means that
1065 it is possible to override any existing attribute with a relationModifier.
1066 And also that it is possible to override everything for the index rule
1067 (except the ones listed in relationModifier). No order is perfect but this
1068 one, we believe, covers more real cases.. The "always" should have been
1069 called "default", since the attributes there can be overridden with all
1072 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1073 compilation phase, but also for yaz-config --cflags output. This allows
1074 us to have public headers with Libxml2 stuff in them . It should also,
1075 eventually, make Libxml2 checks redundant in packages using YAZ, such
1078 --- 2.1.22 2006/06/15
1080 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1081 stored in uri, message and details.. Previously diagnostics were stored
1082 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1083 compatibility.. but he's probably the only one affected, so.
1085 Added support for CCL, compiled on the client side, in ZOOM-C. This
1086 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1087 input; the resulting query objects can be used for for searching with
1088 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1090 YAZ' configure searches for OpenSSL by default.
1092 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1093 SL_CTX_use_certificate_file. See
1094 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1095 for more info. Thanks to Ko van der Sloot.
1097 --- 2.1.20 2006/06/02
1099 Bug #600: SRU GET, POST support for yaz-client. Introduced
1100 command 'sru' which selects method SOAP/GET/POST.
1102 Allow missingValueAction to be specified for the sortspec string -
1103 function yaz_sort_spec. By default, the missing value action is null.
1104 Use ! to specify "abort". Use = followed by stringvalue to specify default
1107 Ensured that Present-handler (if defined) is called in GFS before any call to
1108 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1109 searchRetrieve requests.
1111 Documentation for YAZ is now based on the Docbook XML/XSLT using
1112 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1113 is no longer depending on jade/openjade or docbook-to-man scripts.
1114 PDF is no longer part of the distribution - but can optionally be
1115 made using DSSSL/jadetex or FOP.
1117 Added retrieval handling support in Generic Frontend Server to support
1118 conversion between MARC/XML as well as XSLTtransforms. See
1119 etc/yazgfs.xml for an example.
1121 Added Authentication support to Generic Frontend Server in SRU
1122 mode. Authentication using HTTP Basic is supported, as is the use
1123 of 'x-username' and 'x-password' parameters in the request itself.
1125 Added support for a new character set MARC8s identical to MARC8 except
1126 that it converts combined characters to single Unicode characters in the
1127 Latin-1 range (when possible).
1129 --- 2.1.18 2006/04/24
1131 ASN.1 compiler 0.4: generates brief Doxygen file header for
1132 generated .h/.c files.
1134 Utility yaz_iconv now supports conversion to MARC-8.
1136 New facilities for the MARC module. The reading - and writing of
1137 content are separate methods for the yaz_marc_t handle. The following
1138 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1139 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1140 format). Write functions have prefix yaz_marc_write_.. The existing
1141 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1142 available. Removed support for OAI-MARC and simplexml (not the
1143 simplexml from PHP5).
1145 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1146 to be returned for this connection.
1148 --- 2.1.16 2006/03/31
1150 Allow multiple languages and charsets to be specified with
1151 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1152 negcharset iso-8859-1,utf-8
1154 Translation of proximity nodes from CQL into PQF now works.
1156 Moved to automake 1.8, 1.9.
1158 Added function yaz_log_set_handler which allows a log handler to be
1159 installed. This handler will be called for all log messages. Output
1160 to file is also produced; but that can be disabled by passing NULL
1161 fname to yaz_log_init_file.
1163 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1165 For SRW (including GFS), accept application/soap+xml as content-type
1168 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1169 produces NO stylesheet reference even if a default stylesheet is specified
1172 --- 2.1.14 2006/03/14
1174 Updated Windows package to include yazd.dll + yazd.lib for the
1175 Development component.
1177 If the environment variable YAZ_LOG is set, then it is used as a
1178 string indicating the default level of logging to use if not
1179 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1180 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1181 used as before. So, for example, to omit warnings from YAZ logging,
1182 export YAZ_LOG=-warn
1184 cql_transform() now map structure and other attributes before indexes,
1185 so that index-specific structures and other attributes can override
1186 defaults. So now a combination of mapping specifications such as:
1188 index.dc.date = 1=date-modified 4=5
1189 does the right thing.
1191 cql_transform() now also respects the "always" mapping specification,
1192 which establishes an initial set of attributes to be used for all
1193 terms except where overridden by more specific attributes associated
1194 with the index, relation or modifier.
1196 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1197 which mode to use; one of "post", "get" or "soap" (SRW, default).
1199 Fixes for yaz_iconv routines: changed trie-based character set conversions
1200 to use only non-negative values for bit fields due to Sun's C compiler not
1201 supporting negative values.
1203 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1204 sequences where not read correctly. Fix by Rustam Usmanov.
1206 Updated win/makefile to use options, settings which makes things
1207 compile with VS C 2005.
1209 --- 2.1.12 2006/02/01
1211 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1213 In ZOOM socket code, use select instead of poll on MacOSX.
1215 ZOOM-C now support client-side compilation of CQL into RPN that is
1216 sent to the server, enabling CQL to be used against all Z39.50
1217 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1218 ZOOM_query object, and submit it using ZOOM_connection_search().
1219 The CQL-to-RPN translation uses a configuration file, the name of
1220 which must be specified in the Connection's "cqlfile" option.
1222 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1223 function, which takes as its start-term parameter a ZOOM_query object
1224 (which may have had either CQL or RPN set into it).
1227 --- 2.1.10 2005/11/29
1229 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1230 GFS to support this as well. Backend handler, bend_srw_update, does the
1231 update work. Code contributed by Ko van der Sloot.
1233 Allow retrieval of Search Result-1 information in ZOOM by the use of
1234 options that are attached to a result set. ZOOM documentation updated
1237 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1238 UTF-8 conversion. Patch by Raj Patel.
1240 Added option -m to GFS to control formatting of timestamps in log file.
1242 Added 'exit' as synonym for 'quit' in yaz-client
1244 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1245 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1246 for the new members. Patch by Ko van der Sloot.
1248 Added support for SRU POST. It is supported for content-type
1249 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1251 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1252 Instead make the library libyaz.la multi-threaded. Threading as a whole
1253 can still be disabled by configure option --disable-threads. Previosly,
1254 with older GLIBCs there were problems with MT libs under Apache. This
1255 has now been fixed a long time ago.
1257 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1260 CQL module modified to be case insensitive for relations/indexes/operations.
1262 Fixed bug in CQL transform code: incorrect value relationModifieder
1265 Added 'show all' command for yaz-client which retrieves all results
1268 Added new yaz-client, xmles, which takes a (private) OID and
1269 a document to be sent as an extended service request.
1271 Describe new yaz-client commands wait_response and set_auto_wait.
1273 Increase TCP/IP listener backlog from 3 (which I am guessing was
1274 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1275 that the socket will queue as many incoming connections as it's able
1276 to handle ongoing connections. In other words, it will never now
1277 refuse a connection that it would be able to handle merely because
1278 it's not got around to accepting() enough of the pending connections
1279 yet. This is the behaviour anyway under Linux, where the listen()
1280 argument is ignored; but not under BSD and on systems such as
1281 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1282 YAZ-based servers should now be uniform across operating systems in
1285 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1286 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1287 This allows yaz-marcdump to read large MARC batches (>2 GB).
1289 Modified all YAZ source files - except the source which is auto-generated
1290 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1293 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1294 corresponding to the existing *_setl() function. These allow option
1295 values containing arbitrary valuues.
1297 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1298 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1299 except that it returns an indicator of whether or not the sort
1300 criterion was accepted (0 for OK, -1 for invalid).
1302 --- 2.1.8 2005/06/07
1304 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1305 MARC output rather than returning "new" buffer.
1307 yaz-client warns about unknown init options.
1309 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1311 --- 2.1.6 2005/05/24
1313 Added support for SRW sort in Generic Frontend Server. Patch
1314 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1315 sortKeys - or NULL if none is provided.
1317 Fixed bug #307: It was impossible to specify indefinite/no timeout
1318 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1321 Added support for multiple languages and charsets to be specified in
1322 ZOOM. Each charset/language is separated by a blank. If negotiation is
1323 in effect in init-response, Option
1324 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1325 Code based on patch by Vasiliy Osadchuk.
1327 Fixed bug #306: infinite recursion that occurred when calling
1328 yaz_log_level_init as the first call (before other log level or
1331 Fixed bug in scan handling in front end server: if preferred-Position-In-
1332 Response was non-present, a NULL pointer referece was performed.
1334 --- 2.1.4 2005/04/26
1336 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1337 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1338 now defined for all those error codes. So instead of putting 109 in
1339 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1340 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1342 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1345 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1347 Program yaz-client now exits and produces an error message if multiple
1348 Z39.50 servers are specified on the command line (none or one allowed
1351 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1354 --- 2.1.2 2005/03/16
1356 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1358 Fixed bug #272: Preserve spacing for CCL terms.
1360 --- 2.1.0 2005/03/14
1362 Added support for virtual hosts and multiple backend servers for
1363 the YAZ frontend server. The configution is XML based and
1364 support specificition of CQL to RPN mappings and explain information.
1365 See section "Virtual Hosts" in the YAZ manual.
1367 Extended OPAC display utility. OPAC display utility renders
1368 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1369 to supplement yaz_marc_decode_wrbuf.
1371 Fixed a bug in MARC decoder that could caused it to crash for some
1372 invalid MARC records. More diagnostics and warnings where added in
1373 XML output (warnings, etc are stored in comments).
1375 --- 2.0.34 2005/02/08
1377 Fixes for UNIX domain sockets. Bug #261.
1379 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1381 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1382 Added yaz_marc_subfield_str which defines subfield lead string which is
1383 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1384 yaz_marc_endline_str which defines end of fields string used in
1385 YAZ_MARC_LINE format. Default string is newline.
1387 Experimental support for MarcXChange. This format can be produced
1388 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1389 http://www.bs.dk/standards/MarcXchange.xsd
1391 Added yaz-client commands scansize that sets maximum number of
1392 entries to be returned by scan.
1394 --- 2.0.32 2005/01/11
1396 Added support for SRW scan in yaz-client and Generic Frontend Server.
1398 * Added whereInList member to SRW Scan Term.
1400 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1402 Fixed NMEM system to return aligned blocks on the smallest boundaries
1403 that are suitably aligned for all possible types on the particular
1404 architecture YAZ is being built for.
1406 --- 2.0.30 2005/01/04
1408 Fixed numerious warnings that was issued with newer versions of GCC.
1410 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1411 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1414 Make YAZ Generic Frontend Server slightly faster.
1416 Enhance (and reduce) logging for Generic Frontend Server.
1418 Revert YAZ log system so that it flushes every write operation
1419 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1421 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1422 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1423 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1424 will effectively disable old definitions.
1426 --- 2.0.28 2004/11/09
1428 Added yaz_log_time_format which specifies log format using
1431 Added yaz_log_module_level which returns mask for a module. Value
1432 is non-zero mask a if module is enabled; zero if disabled.
1434 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1435 in include/yaz/cql.h.
1437 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1439 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1441 Fixed bug #172: RPM builds does not enable SSL.
1443 Doxyfile.in part of dist. Doxyfile generated by configure.
1445 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1446 are given and the corresponding component does not exist.
1448 Extend CCL documentation in YAZ reference. Describe r=r.
1450 --- 2.0.26 2004/10/01
1452 Fixed MARC->MARCXML conversion to properly deal with
1453 fields, subfields, indicators having non-ASCII characters.
1455 Fixed MARC->MARCXML conversion so that ASCII control characters
1456 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1459 Added YAZ GFS support for conversion from Z39.50 surrogate
1460 diagnostics to SRW surrogate diagnostics.
1462 Bug fix: YAZ GFS did not return schema in explainResponse.
1464 --- 2.0.25 2004/09/30
1466 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1467 now converts recordSchema to elementSetName as well as schema URI.
1469 Fixed bug in COMSTACK that prevented HTTP request packages from being
1472 --- 2.0.24 2004/09/29
1474 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1475 does not require white-space before and after the dash in a range, e.g.
1476 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1479 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1480 due to new GCC removing "redundant" code.
1482 Added yaz-client commands scanpos and scanstep that sets preferred
1483 position and step-size for scan.
1485 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1487 Added CCL utility ccl_qual_buf which parses one or more CCL
1488 spec lines in a buffer.
1490 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1491 of name and value - ignoring empty lines and comments.
1493 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1495 Added odr_get_element_path which returns current element path for an
1496 ODR handle. This utility is useful in error handling or user-defined
1499 Added ODR_PRINT utility odr_set_stream which is is a more generic
1500 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1501 to a write function and pointer to close function. The close function - if
1502 non-NULL - will be called during odr_destroy.
1504 Fixed bug in CCL parser where truncation char was not removed from
1505 right side when truncation=both was in effect.
1507 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1510 --- 2.0.23 2004/08/11
1512 Fix buffer overrun in CQL parser when dealing with proximity (%).
1514 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1515 to UTF-8/UCS conversion is now only based on codetables.xml.
1517 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1519 --- 2.0.22 2004/08/06
1521 Add support for more "commit changes" in ZOOM (uses Extended Services).
1523 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1526 Yet another small fix for configure of SSL.
1528 --- 2.0.21 2004/05/14
1530 Fix SSL libs for configure when --with-openssl=DIR is given.
1532 --- 2.0.20 2004/05/10
1534 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1536 SSL comstack now uses yaz.pem certificate file on server side
1537 by default. Certificate filename can be configured by calling
1538 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1540 Fix bug regarding multiple calls to ZOOM_connection_connect.
1542 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1544 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1545 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1547 ZOOM now allows inspection of X509 peer certificate for verification.
1548 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1550 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1551 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1552 as "modular" but it simplifies things.
1554 Added cs_get_peer_certificate to that returns peer X509 PEM.
1556 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1557 NULL if SSL is unavailable.
1559 Documentation about MARC decoding tools.
1561 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1563 --- 2.0.19 2004/03/30
1565 Rename CHANGELOG to NEWS to follow GNU style packing.
1567 Fix bug with missing initialization of member in init_diagnostics.
1568 This bug affects threaded version of GFS server.
1570 --- 2.0.18 2004/03/20
1572 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1575 Ensure zlib.dll is packed with Windows install.
1577 --- 2.0.17 2004/03/17
1579 Fix encoding of xsd:string to use text instead of CDATA.
1581 Fix endless loop in CQL parser with unbalanced ".
1583 Use a more compact way to store MARC-8 conversion tables.
1585 --- 2.0.16 2004/03/16 Debian only
1587 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1590 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1595 --- 2.0.15 2004/03/01
1597 Another fix for decoding of XML packed records.
1599 --- 2.0.14 2004/02/25
1601 Fixes for Chunked encoding. White space not ignored after length spec.
1603 Update NS and use default NS for SRW diagnostic elements.
1605 --- 2.0.13 2004/02/23
1607 Implement ZOOM_resultset_cache_reset which resets record cache.
1609 Implement ZOOM_resultset_sort which sorts a result set.
1611 Implement chunked HTTP transfer.
1613 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1615 --- 2.0.12 2004/02/16
1617 Added member 'schema' to bend_explain_rr structure so that backend
1618 can specify explain record identifier. Defaults to Zeerex 2.0.
1620 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1622 --- 2.0.11 2004/02/16
1624 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1627 Added init command for yaz-client which sends "extra" init request.
1629 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1630 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1632 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1634 Make ZOOM error code for "invalid query".
1636 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1638 --- 2.0.10 2004/02/05
1640 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1643 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1645 Added option -p <file> to make Generic Frontend Server to write PID file.
1647 Added option -D to put Generic Frontend Server in background on its own.
1649 Make ZOOM C recognize option "password". If unset, "pass" is used
1650 (for backwards compatibility).
1652 Fixed a bug in Generic Frontend Server that could make it crash if a
1653 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1656 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1657 Must be issued before open, in order to be in effect.
1659 --- 2.0.9-6 2004/01/12 Debian/Windows
1661 Make the SRU server more picky WRT unknown params, etc.
1663 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1665 New YAZ client command, options, that sets Z39.50 options.
1667 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1668 options from a string of tokens (one token for each option bit).
1670 Update SRW diagnostic code messages.
1672 --- 2.0.9-5 2004/01/07 Debian/Windows
1674 Handle user defined stylesheet for SRW/SRU.
1676 --- 2.0.9-4 2004/01/06 Debian/Windows
1678 Fix bug in decoding of Content-Length.
1680 --- 2.0.9-3 2004/01/06 Debian/Windows
1682 Fix a bug with decoding of XML packed records.
1684 --- 2.0.9-2 2004/01/05 Debian only
1686 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1688 Fix bug in SRW/SRU diagnostics decoding.
1690 --- 2.0.9 2004/01/05
1692 Fixed bug in Generic Frontend Server which could drop records exceeding
1693 preferred message size. Reported and fixed by Irina Dijour.
1695 Fixed calculation of package size for structured records in Generic
1696 Frontend Server. Reported and fixed by Irina Dijour.
1698 Fixed namespace for SRW/SRU diagnostics.
1700 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1702 --- 2.0.8 2003/12/22
1704 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1705 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1708 CQL changes to reflect recent changes to the specification:
1709 * Documentation talks about context sets instead of index sets.
1710 * Documentation talks about indexes instead of qualifiers.
1711 * The CQL-to-PQF transformer's configuration file now uses
1712 "index.set.name = <attributes>" instead of the old form
1713 "qualifier.set.name = <attributes>". (Both forms are still
1714 understood but the latter is deprecated.)
1715 * CQL terms with no explicit index specified are now interpreted as
1716 cql.serverChoice instead of srw.serverChoice (which of course
1717 behaves exactly the same.)
1719 --- 2.0.7 2003/12/16
1721 MARC conversion can now generate ISO2709 output in another
1722 character set. yaz-marcdump uses this facility if you invoke it
1725 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1726 functions from there can be used from C++.
1728 --- 2.0.6 2003/12/04
1730 Frontend server now transfers memory from decoded packages to stream
1733 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1734 references to show up.
1736 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1737 the ZOOM Abstract API. The older names for the same options are still
1738 also supported for the benefit of old applications.
1740 ZOOM-C supports "implementationId" and "implementationVersion" options
1741 to go along with "implementationName". These allow the user code to
1742 specify identification strings to be sent to servers.
1743 Add OID for the new ExtLite attribute set.
1745 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1746 as requested/supplid by Ere Maijala <ere@atp.fi>
1748 For generic frontend server, reverse the order of
1749 "toolkit-supplied / application-supplied" strings sent as implementationId,
1750 Name and Version. Also, remove the spaces around the slash. This brings
1751 the GFS in line with the behaviour of ZOOM-C on the client side.
1753 Add function ZOOM_scanset_display_term.
1755 yaz-client shows scan displayTerm if present.
1757 Utility yaz-iconv is now installed by default along with the man page
1760 Extend configure check for OpenSSL to use pkg-config where available (such
1763 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1764 server to specify uid/gid/mask for socket using the format
1765 unix:[user=uid,][group=gid,][umask=mask,]file=path
1766 If file= is omitted the existing format is assumed, e.g.
1768 in which case the mask is 0666 (rw for everybody).
1770 Major restructure of YAZ source. All source in libyaz is in src directory.
1771 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1772 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1774 Added man page for utility yaz-marcdump (used to be called marcdump).
1775 yaz-marcdump is installed by 'make install'.
1777 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1778 of incoming package failed.
1780 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1782 Change prototype of odr_perror: add const to message string.
1784 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1786 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1787 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1788 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1789 DNS lookup. There should not be any compatibility problems with this
1790 assuming that blocking=1 or 0 is used.
1792 Fix bad reference in UNIX comstack in function cs_addrstr.
1794 Fix for compilation on AIX.
1796 The generic front-end server (server/seshigh.c) now supports returning
1797 Init diagnostics to the client in User-information-field, in
1798 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1801 --- 2.0.4 2003/09/04
1803 Allow any CQL relation (not just all,any,exact,scr).
1805 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1806 that features the same UI.
1808 Implemented command update0 in YAZ client which is equivalent to
1809 update but uses old of Ext Update ASN.1.
1811 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1812 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1813 Previously no OID was used for this info.
1815 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1816 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1817 returns 'malformed search term' otherwise.
1819 SortResponse member resultCount now set to NULL in sort handler of
1822 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1825 Add three new utility functions for translating OIDs between various
1826 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1827 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1828 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1829 char *oid_to_dotstring(const int *oid, char *oidbuf);
1830 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1832 Reverted modifications for ES Update definition for z_IU0Update
1833 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1834 is back to YAZ 2.0.2.
1836 String value attributes for CCL parser.
1838 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1839 which their FirstSearch server returns in Init responses, sometimes
1840 carrying useful diagnostic information when Init fails. This has the
1841 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1842 "z39.50/oclcui.asn", where its definition is somewhat different from
1843 what OCLC document on their web-site, as required to interoperate with
1846 Support for anonymous authentication in yaz-client. Use the command
1849 * Fix the OID of the Index Data-local "admin" Extended Service from
1850 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1851 the 1000, which indicates a locally-defined OID, was a mistake.
1853 --- 2.0.3 2003/06/20
1855 Fix CCL directive @case handling so that it affects string match for
1856 both CCL keywords and qualifiers.
1858 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1859 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1860 Decoder has been updated with ASN.1 changes as listed in
1861 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1862 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1863 z_IUUpdate, remains unchanged.
1865 ZOOM_record_get may now return a record in a specific character set.
1866 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1867 "from" is the character set of record as returned by target. "to" is
1868 the character set to be returned. If omitted, "to" is UTF-8.
1870 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1872 New ODR utility, odr_getelement, which returns name of element for
1873 which encoding/decoding failed.
1875 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1876 in cases where a required element was omitted.
1878 Bug fix: some MARC8 sequences were not converted.
1880 New ZOOM option "step" which specifies number of records to be
1881 retrieved in one chunk. Used in conjunction with "start" and "count".
1883 SRW support for yaz-client. Use scheme http: to use it, e.g.
1886 yaz-client no longer does (un)intelligent character set conversions
1887 by default. Can be enabled with charset and marc_charset commands.
1889 xmalloc trace fix for 64-bit systems such as DEC alpha.
1891 Solaris 2.6 compile fix.
1893 New function, cql_strerror() translates SRW error codes, as returned
1894 by cql_transform_error(), into human-readable English strings. Used
1895 in yaz-client diagnostics when appropriate.
1897 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1898 converts it into a type-1 query which is sent to the server. This
1899 makes CQL available for use with all Z-servers, as opposed to the tiny
1900 minority that can handle CQL queries themselves.
1902 --- 2.0.2 2003/04/28
1904 New Debian package layout similar to the Redhat Package layout.
1906 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1907 and search result respectively.
1909 --- 2.0.1 2003/04/25
1911 Redhat package is now several packages: libyaz (runtime libraries),
1912 libyaz-devel (development and documentation, and yaz (utility programs).
1913 Package spec file by Morten Bogeskov.
1915 New member 'schema' in struct bend_fetch_rr which the name of requested
1916 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1917 handler MAY set this to reflect the schema of the returned record.
1919 New member 'display_term' in struct scan_entry. GFS now sets member entries
1920 and allocates scan entries to be filled by user scan handler. In previous
1921 version, entries member was allocated by the scan handler. That still works,
1922 but the GFS will ignore member display_term - assuming it was NOT set by
1923 the handler. The fact that the GFS now allocates the entries both allows
1924 for new members and makes a scan handler easier to write.
1926 Fix CQL lex buffer overflow.
1928 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1929 SRU default recordPacking is string.
1931 SRU protocol support for frontend server.
1933 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1935 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1937 Added scan for the ZOOM shell (zoomsh).
1941 * String Identifers for Schemas (Amendment 5).
1942 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1943 Old definition for schema
1944 Odr_oid *schema; /* OPT */
1949 Z_InternationalString *uri;
1950 #define Z_Schema_oid 1
1951 #define Z_Schema_uri 2
1954 * resultCount parameter to Sort Response (Amendment 1).
1955 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1957 Support for SRW 1.0 over HTTP. This is an optional feature and
1958 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1961 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1962 on the same port. SRW SearchRetrieveRequests are mapped
1963 to bend_init,bend_search,bend_fetch,bend_close.
1965 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1967 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1968 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1970 ZOOM connections are SRW based if schem http is used for hostname
1971 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1972 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1974 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1975 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1976 distance=n, order=true/false, relation=le, prox unit=word. If
1977 n is omitted, distance 1 is used.
1979 Fixed problem with C compiler include path in wrong order.
1981 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1982 on Solaris. Patch from Ko van der Sloot.
1984 New MARC decode API. All new functions operate on a yaz_marc_t
1985 handle. The most important new functions are: yaz_marc_create,
1986 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1987 decode and destroy respectively. Decoder can produce formats
1988 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1989 include/yaz/marcdisp.h.
1991 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1992 to UTF-8, UCS-32, wchar_t or Latin-1.
1994 * Prototypes for yaz_iconv_-functions moved to separate header
1995 include/yaz/yaz-iconv.h.
1997 Make a few private functions 'static' in unix.c. This prevents
1998 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2000 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2001 are set when Init Response is received.
2003 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2004 but returns diagnostic set as well.
2006 New function yaz_strerror which is a portable wrapper for
2007 strerror/strerror_r/GetLastMessage.
2009 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2010 is returned for MARC. If type is "oai", then OAI MARC is returned.
2012 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2015 --- 1.9.2 2002/11/26
2017 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2019 Fix bad race conditions on SIGTERM and terminate gracefully in
2022 Move retrieval (data1) module to Zebra since nobody seems to be
2025 Add GRS-1 render for ZOOM using same format as yaz-client.
2027 --- 1.9.1 2002/10/05
2029 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2031 Fix broken ESpec handling in data1 module.
2033 SGML reader parses comments and makes them part of the data1 tree.
2035 Added several type casts so that YAZ compiles as C++ code.
2037 ZOOM didn't handle PDU encoding failures properly.
2039 Added more Bib-1 diagnostics (approved extensions).
2041 GNU configure: better check for iconv.
2043 More portable use of accept, getpeername. Check for socklen_t. Use
2044 int/size_t if socklen_t is not defined.
2048 PQF parser rejects bad queries - including those with extra
2049 characters in them. PQF parser used to silently ignore that.
2050 Cleaner API for PQF added, which allows you to get detailed
2051 error information for bad queries (see yaz/pquery.h).
2053 Fixed bug in ZOOM_record_get for type "database".
2055 Implemented mini iconv library supporting conversions between
2056 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2058 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2060 --- 1.8.9 2002/08/20
2062 Fixed ZOOM C record cache so that preferredRecordSyntax and
2063 elementSetName is used to check for already fetched records.
2065 --- 1.8.8 2002/08/02
2067 Added three members in bend_initrequest structure to facilitate
2068 character set negotiation.
2070 Fixed a bug in frontend server that could cause indefinite
2071 loops under rare conditions.
2073 Revised character set utilities (charneg.h) so that encoding
2074 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2076 For PQF, directive @term <type> sets term type for Scan/Search.
2077 Here <type> is general, string, numeric, null. The term type
2078 is inherited - just like @attr.
2080 New call odr_set_charset that sets character set conversion for
2081 international-strings on a ODR stream. Prototype is:
2082 int odr_set_charset(ODR o, const char *to, const char *from);
2083 The InternationalString is still represented as C string in YAZ
2084 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2085 won't). On the protocol level, you can use any encoding.
2087 Support for UNIX sockets in ZOOM.
2089 Solaris recv sometimes returns errno == ENOENT. It is treated as
2090 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2092 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2093 both client and server. Code by Morten Bogeskov.
2095 --- 1.8.7 2002/05/22
2097 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2098 that they can be used directly from Visual Basic. You must recompile
2099 your windows APP if you're using ZOOM.
2101 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2102 Commands "lang" and "charset" sets language and character set respectively.
2103 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2104 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2106 Attributes from multiple CCL fields may be OR'ed rather than merged
2107 using directive "@field or". Fields are still merged by default -
2108 equivalent to "@field merge".
2110 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2113 Fixed bug in zget for parameter ExtendedServicesResponse.
2117 --- 1.8.6 2002/03/25
2119 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2121 Client displays USR.1:SearchResult-1 (hits per term).
2123 Additional Search Info for search in Generic Frontend Server.
2125 Fixed CCL parsing of "field=s".
2127 WIN32 installer - using the excellent NSIS software from nullsoft.
2129 Fixed CCL parsing of "field = - <number>".
2131 Added function yaz_marc_decode that decodes MARC for line mode
2132 display or XML (similar to that used by JZKit).
2134 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2135 Z39.50. But ISO/ILL was, however.
2137 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2138 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2140 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2141 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2143 --- 1.8.5 2002/02/03
2145 New YAZ client features: Command completion and new commands:
2146 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2147 Code provided by Jacob Poulsen.
2149 New call oid_trav, that visits all registered OIDs via callback.
2151 Function ZOOM_record_get now returns const char pointer rather than
2152 void pointer. It saves a lot of type casts.
2154 For YAZ client, command "auth" now allows you to set authentication
2155 in IdPass style. It is enabled when three tokens are given - order
2156 is user, group and password.
2158 Fix memory leaks in MARC record handling for ZOOM.
2160 New option for YAZ client, -k <kilobytes> that sets
2161 maximum record size. Similar to -k option for generic frontend
2162 server and yaz-ztest.
2164 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2166 Prefix query parser reports "fail" when bad attribute set is given.
2168 Fix in MARC decoder. Proximity logging. Fix for attribute set
2169 in scan handler for server. Patches by Shigeru Ishida.
2171 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2174 Configure option --with-openssl=<dir> now works when a directory is
2175 specified. Patch provided by Morten Bogeskov.
2177 New option for YAZ client, -u <auth>, that sets authentication.
2179 ZOOM fix: error information was sometimes "missing", since error
2180 was cleared/reset too when it shouldn't.
2182 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2184 --- 1.8.4 2002/01/04
2186 Scan for ZOOM API. New object ZOOM_scanset. New functions
2187 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2188 ZOOM_scanset_destroy.
2190 New ZOOM function, ZOOM_connection_last_event, that returns type
2191 of last event (such as "receive data", "send data", "apdu received",
2194 New ZOOM option, schema, that specifies schema for retrieval.
2196 New CCL feature. Qualifiers can be aliases for one or more
2197 other qualifiers (if more than one is given, OR is used).
2199 ZOOM uses named result sets if target supports it.
2201 Two new YAZ client commands: . (dot, which sources a script of YAZ
2202 client commands), and ! (to execute shell command.). Implemented
2205 Working on Debian packages.
2207 --- 1.8.3 2001/11/19
2209 YAZ client enables named result sets only if target supports it.
2211 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2213 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2214 with key="host" to get same result.
2216 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2217 Function Z3950_resultset_record(s) returns references to records
2218 "owned" by resultset. To become owner use Z3950_record_clone.
2220 Function z_ext_record handles Extended Services. Thanks to
2223 --- 1.8.2 2001/11/12
2225 CCL Parser fix: ignore token comma when dealing with and-lists.
2227 Documentation updates for COMSTACK.
2229 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2230 Changed prototype Z3950_records. For some functions, int parameters
2231 were changed to size_t.
2233 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2236 New MARC decode/display function, marc_display_exl, which properly rejects
2237 non-ISO2709 records. YAZ client uses it.
2239 --- 1.8.1 2001/10/29
2241 Fix bug: local attribute set wasn't set correctly in PQF strings.
2245 * Old Z39.50 codecs no longer supported.
2247 Added ZOOM C binding. See http://zoom.z3950.org/
2249 Renamed states for COMSTACKs to avoid confusion with events.
2251 Implemented cs_look and proper cs_rcvconnect.
2253 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2255 Configure detects POSIX threads on OpenBSD.
2257 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2258 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2260 When error is returned from present handler, non-surrogate diagnostic
2261 is returned in present response (and fetch handler is no longer called).
2263 * Minor adjustments to pquery parser (PQF). Token characters may be
2264 escaped by using backslash (C-style).
2266 PQF parser allows string attribute values to be specified. For @attr,
2267 non-numeric characters after the equal-sign are treated as strings
2268 (e.g. @attr 9=title).
2270 CCL trunction character may be defined (@truncation in file)
2272 * function zget_ExtendedServicesRequest sets waitAction to
2273 waitIfPossible (was wait).
2275 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2278 CCL operator names may be set in field definition files (CCL_bibset).
2279 See ccl/bib1 for an example.
2281 Fixes in ASN.1 compiler for C++ compatibility.
2283 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2284 and "op_or" to avoid conflict with C++.
2286 Fixed problem with GNU readline detection on Redhat 7.0.
2288 Added step-size for Scan backend handler.
2290 Fixed bug that made the frontend server crash when no attribute
2291 set was specified for scan.
2293 Front-end server automatically switches to original working directory
2294 when installed as an NT service. Previously -w had to be specified to
2297 Added extended attributes for retrieval module (data1), so that data1
2298 records carry d1_readXML/SGML attributes. d1_read also supports
2299 null-data rules ( <tag/>)
2301 On UNIX when POSIX threads are available, a separate library libyazthread
2302 is created. Programmers should link with that library and the yaz library
2303 when using threads. The reason for the split was that some applications
2304 on Linux, such as Apache, doesn't work well when using shared objects that
2307 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2308 (or any frontend server) in SSL mode by specifying ssl: followed by
2309 address. Only tested on UNIX.
2311 Added feature for CCL module. Virtual structure s=al or s=ol generates
2312 and-list and or-list respectively instead of phrase search.
2316 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2317 log_mask_str. This was done to avoid name conflicts with other libraries
2318 (such as other PHP extensions).
2320 Added raw OID member for preferred record syntax (request_format_raw)
2321 and returned record syntax (output_format_raw) for backend fetch method.
2323 Config file yaz-config now accepts options so that it returns specific
2324 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2326 Shared library support for UNIX using GNU libtool.
2328 * Modified backend interface. Request/Response struct's replaced by
2329 one read/write C struct. For example bend_fetchrequest and
2330 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2331 Every handler - even search has to be registered in bend_init
2332 handler. This means that the YAZ library no longer refers to
2333 external functions and it makes it possible to make the whole
2334 thing a single DLL/SO.
2336 Added Segment handler for backend server.
2338 Added Zmbol/Zebra administrative functions to YAZ client.
2340 Threaded frontend server on UNIX (when POSIX Threads are available).
2341 Starting the server with option -T enables multi-threading.
2345 Added configure option --enable-comp/disable-comp to control use
2346 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2347 located in sub directory asn.
2349 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2350 in ${exec_prefix}/bin along with the other programs yaz-client and
2353 GNU automake used to maintain makefiles.
2355 Added several OID's.
2357 Changed retrieval module so that we can load records with no abstract
2358 syntax defined. Tagpaths in these records are fully composed of string
2361 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2365 On UNIX, the generated makefile now supports a proper 'make install'.
2366 The prefix can be set via GNU configure to set the install location
2367 (default is /usr/local).
2369 * YAZ programs client and ztest were renamed to yaz-client and
2370 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2371 locations, such as /usr/bin,/usr/local/bin,etc.
2373 * YAZ Header files were moved from include to include/yaz. YAZ Header
2374 files are referred to as include <yaz/log.h> rather than <log.h>.
2375 The YAZ include path (-I ..) is therefore the same as before. Programmers
2376 should update their #include statements or use -Ipath/include/yaz
2377 instead. The main motivation for doing this change is that YAZ header files
2378 can be installed in "standard" locations /usr/include,/usr/local/include
2379 without introducing conflicts, since ALL YAZ header files are stored
2380 in subdirectory yaz (under /usr/include for example).
2382 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2383 rather than project/workspace files. We switched because project files
2384 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2387 Changed name of logging function, logf, to yaz_log, to prevent name
2388 clash with some math-log functions. The YAZ header log.h defines logf
2389 to yaz_log (#define) so there should be no incompatibilities by this
2392 Added bend_start/bend_stop handlers for server. These handler are
2393 called on start/stop of server. For windows they are called whenever
2394 a service is started/stopped.
2396 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2397 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2398 in util/yc.tcl. The auto-generated C code structures are, in a few
2399 cases, incompatible with the old decoders. There are differences in the
2400 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2401 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2402 The preprocessor variable ASN_COMPILED is defined when the compiled
2403 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2404 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2405 wish to use the old encoders/decoders you can specify --disable-yc
2408 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2409 version so that it supports both new - and old version of DB Update
2411 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2412 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2413 change. The name parameter can be set to 0 in which no name is specified
2414 for the construction. The macros odr_implicit and odr_explicit sets name
2415 parameter to zero for the construction involved. New macros
2416 odr_implicit_tag and odr_explicit_tag are similar to the others,
2417 except that a name parameter is added. For programmers' that don't use
2418 ODR they probably only need to change the call to z_APDU and z_External.
2420 Added access control facility by interfacing the TCP wrapper library.
2421 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2422 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2423 name of the daemon and enables the access control as specified in
2424 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2426 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2427 den Dool <H.M.vdnDool@kub.nl>.
2429 Added reference ID parameter to most functions in server API - refer
2430 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2432 Changed name of ccl library to libccl.a (was ccl.a).
2434 Fixed bug in decoder for Explain (Category TargetInfo).
2436 Added support for GNU readline in client. Thanks to Jacob Poulsen
2437 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2439 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2440 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2441 IMPLEMENTATION! This change was made to the development version before
2442 the ZIG decided to retract the amendment. If any users MUST be
2443 compatible with the original Update definition, PLEASE CONTACT US, and
2444 we will include a separate definition corresponding to the old Update
2445 ES. Note that because of the change to the ASN.1 of the
2446 TaskPackageRecordStructure we cannot define a single structure that
2447 will support both versions.
2449 * Added const modifier to buffer parameter for some ODR/BER encoding
2450 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2451 completeWAIS, odr_dumpBER.
2453 Fixed bug in client.c which caused a crash when a scanResponse didn't
2454 contain positionOfTerm.
2456 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2457 * will cause an error in a client if a non-YAZ target sends both a
2458 * list of Scan entries and non-surrogate diagnostics.
2460 Retrieval module enhancements. Tag sets may be typed in the reference
2461 to it. From the .abs-file the "tagset" directive takes a third optional
2462 integer type for the tag set referenced. From a .tag-file the "include"
2463 directive takes a third optional type as well. The old "type" directive
2464 in the tag set itself is still recognized but acts as the default type
2467 Backend interface change. Individual Scan terms returned from bend_scan
2468 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2469 in include/backend.h.
2471 Retrieval module enhancements. Multiple tag sets and attribute sets may
2472 be specified in abstract syntax specs. Revised the error/warning for
2473 logging messages reported by the retrieval module when reading the
2476 Object Identifier system (oid_..) changed. The API is backwards
2477 compatible but the oid-routines now allocates new OID's when needed.
2478 Raw OID's may be specified in oid_getvalbyname.
2480 YAZ now uses GNU configure to generate Makefile(s).
2482 * Minor changes in some of the member names of DeleteResultSetRequest and
2483 DeleteResultSetResponse. See include/proto.h.
2485 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2486 and added member 'languages' in TargetInfo (which was missing).
2488 Changed the way attribute sets are handled in the retrieval
2489 module. These are now cached, just like the abstract syntaxes
2492 Changed YAZ so that it links with compiled ASN.1.
2494 Added Explain-schema definitions and mapping routines. The following
2495 Explain categories have been implemented: AttributeDetails,
2496 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2498 Fixed minor bug in Windows version of Server Library.
2500 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2502 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2504 Added EXTERNAL: UNIverse Resource Report (non-standard).
2506 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2507 ENUMERATED and SET OF.
2509 * Added 'const' to some of the char pointer arguments for the
2510 functions, data1_read_node, data1_getelementbytagname,
2511 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2514 Fixed bug in data1_insert_taggeddata - the last_child member of
2515 parent wasn't initialised.
2517 * Changed data1_read_record and data1_read_node so that the supplied
2518 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2519 doesn't refer to any parts of the "SGML"-buffer.
2521 Fixed bug in server library (Windows version of statserv_remove).
2523 * Changed code so that it compiles as C++. The type definition
2524 of Odr_fun which is a member of Odr_arm was changed. The result is,
2525 that an explicit typecast is needed for the fun pointer when
2526 using Odr_arm - as in:
2527 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2529 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2531 Implemented the new structured date and time definition as approved
2532 by the ZIG. Added schemaId element to the specificTag in Espec-1
2533 (also approved at the last ZIG). Thanks to RVDM.
2535 Added some Object identifiers (RVDM).
2537 Changed the Update Extended Service (RVDM).
2539 Added command "refid" to client which specifies referenceId for
2540 the following requests.
2542 Implemented extended service handling for server. See ztest.c
2543 for an example as well as backend.h. New handlers are registerd
2544 in the Init handler.
2546 * Changed interface for sort in server.
2548 Added new members to statserv_options_block. It allows a server
2549 to read options from another source than just the command line. Thanks
2550 to Charles Woodfield.
2552 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2553 renamed to zboolean. Some C++ compilers complained about the name.
2555 Minor changes to gils.abs. Added index 's' (sort) on title
2556 and date/time-last-modified.
2558 --- 1.4pl2 1998/1/30
2560 Fixed bug in server library regarding inetd mode (-i). This bug
2561 was introduced by release 1.4.
2563 --- 1.4pl1 1998/1/29
2565 Added sort facility in client and backend server interface.
2567 Fixed problem with dependencies in Makefile(s).
2569 Fixed bugs for encoders/decoders of extended services and
2572 Implemented sub-tree feature for schemas. Sub-trees are
2573 referenced in *.abs-files. See explain.abs for an example
2574 of the use of this feature.
2576 Modified bib1.att; local attributes for ANY didn't include
2577 ANY itself (only affects use of the retrieval module).
2579 Fixed bug in plain SGML reader in function data1_read_node:
2580 tags with prefix "var" was incorrectly interpreted as variants.
2582 Added feature "sub-schemas" to enable references to - and definitions
2583 of - group of elements.
2585 * Removed member parent from type data1_element (in data1.h).
2587 Implemented function odr_nullval() that returns the value of
2590 * Removed member num_children from data1_node (in data1.h).
2592 Made NT service interface part of the server library. The
2593 function statserv_main uses the NT service when required and
2594 calls the statserv_start / statserv_close routines.
2596 Routine zget_SearchRequest and zget_PresentRequest fills
2597 resultSetName/Id member with "default" instead of "Default".
2599 Fixed memory leak in server. Request queue member wasn't freed.
2601 Fixed nmem_exit so that memory is freed.
2605 Revised the CCL parser utility to be thread safe.
2607 Added function, oid_ent_to_oid, to replace the function
2608 oid_getoidbyent, which is not thread safe.
2610 * Added nmem_init and nmem_exit to initialize and release
2611 NMEM resources. Function nmem_init should be called once in the
2612 initial thread before NMEM/ODR is used. statserv.c and client.c
2613 have been changed accordingly. The change was necessary to make
2614 NMEM thread safe. The NMEM memory pool is shared amongst threads
2615 in a process. Unix-based applications will still work fine without
2618 Added NT Services interface for the the Z39.50 (statserv) Server.
2619 Refer to the ztest.c source on the usage.
2621 Windows 95/NT port using MSVC5.0. Project files are included in the
2624 * Defined new 'global' handle for the retrieval (data1) system. The
2625 new handled, data1_handle, describes the state of the data1 system.
2626 This handle is passed as first argument to virtually all
2627 data1 related routines. The functions data1_create and data1_destroy
2628 creates and destroys a data1 handle respectively.
2630 Added ODR encode stream member to all backend request structures
2631 init, search, scan etc. This stream should be used to allocate all
2632 memory used for the response when thread safe operation is needed.
2634 Changed the comstack utility, cs_addstr, to be thread safe. The
2635 returned hostname string returned by the function is now part the
2638 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2639 function. The cs_straddr takes a COMSTACK handle as argument, so this
2640 function must be used after cs_create and before bind/connect.
2641 This function is thread safe.
2643 Moved test server to 'ztest' directory - generic server code still
2644 in 'server' directory.
2646 Made prefix query (pquery.c) utility thread safe.
2648 Added new function modifier YAZ_EXPORT to 'export' public DLL
2649 functions when using windows (see include/yconfig.h).
2651 Added definitions to the OID database (util/oid.c) (RVDM).
2653 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2655 Added call to ccl_rpn_delete in client program.
2657 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2658 release of RPN structure.
2660 Added support for C++, headers uses extern "C" for public definitions.
2661 With input from RVDM.
2663 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2664 Thanks to Ronald van der Meer (RVDM).
2666 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2668 Added support for private extensions to the OID database
2669 (oid_setprivateoids()). Thanks to RVDM.
2671 Added optional, physical ANY (key replication)
2673 Fixed null-reference problem in GRS-1 output filter.
2675 Proximity operator added to Prefix Query Format (PQF).
2677 In test client command "base" accepts multiple databases.
2679 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2683 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2685 Smallish bug-fixes in the new encoders/decoders (explain).
2687 Bug fixed in DeleteRequest.
2689 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2691 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2693 Added SOIF syntax (using private OID for now) to retrieval module and client.
2695 Added Update extended service.
2697 Added SearchResult-1 additional info structure.
2699 Added optional CCL (ISO8777) interpreter as separate module. Available
2702 --- 1.2 1996/6/10 (1st anniversary release)
2704 Added Summary record syntax. Lightly tested.
2706 Added OPAC record syntax. Untested.
2708 Added ResourceReport service encoders/decoders. Untested.
2710 Fixed bug in z_Unit - wrong tagging on unitSystem.
2712 Fixed bug in the DiagRecs decoder.
2714 Added options for max PDU size and session timeout to frontend-server.
2716 Added documentation of query-language parsers and other supporting utilities.
2718 [frontend-server] Added Attribute set to the bend_scanrequest API.
2720 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2721 surrogate diagnostics were generated.
2723 [retrieval] Allow multiple local values for attribute.
2725 [retrieval] Allow multiple attributes per element in .abs files. index type.
2727 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2729 --- 1.1pl2 1996/4/10
2731 Minor changes, mostly specific to Zebra's requirements (retrieval)
2735 Repaired bug in frontend server when running multiple listening
2736 endpoints in dynamic mode.
2738 z_External() now won't break if a known, ASN.1 value comes encapsulated
2739 in an octet-string. The value will pass through unmodified in an Odr_oct.
2741 Added a bit of code to the demo client to decode & display
2742 ASN.1-structured records represented in the octet-aligned branch of
2743 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2745 Added z_ext_getentbyref() to the ASN module. Doc updated.
2747 * Completed the SCAN definition in the ASN module. This may break SCAN
2748 code based on older YAZ-versions at compile-time. The fix is easy -
2751 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2752 under the SCAN definition. Remember to initialize this, server-people.
2754 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2755 that this does not extend to ODR and ASN.
2757 Comstack allows insertion of established socket (primarily for
2758 inetd-operation of servers). Doc updated.
2760 Front-end server can now start from the inetd in TCP mode. Doc
2763 --- 1.0pl4 1996/1/24
2767 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2768 the rank and record number.
2770 Adjustments to the frontend server.
2772 Fixed diagnostic BER dumper. It ignored the file argument.
2776 Various changes to retrieval module.
2778 Changed the union discriminators of the protocol files from enums to
2779 ints paired with #defines.
2781 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2784 *Changed operator in the RPN structure to 'roperator', again to avoid a
2787 Fixed problems in Explain decoders/encoders.
2789 --- 1.0pl2 1995/12/6
2791 Memory bug in log module fixed.
2793 --- 1.0pl1 1995/12/5
2795 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2797 Bug in Explain DatabaseInfo module fixed.
2799 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2803 The shift to v1.0 signals that we now consider the *core* functionality
2804 of YAZ reasonably stable (the core being more or less equivalent to
2805 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2806 tested (Explain not at all - though that will happen soonish).
2808 Minor changes to code to support Windows port.
2810 Various minor changes after we're getting to use GRS-1 & co. more.
2812 Added Espec-1 format.
2814 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2815 of the protocol and it cannot be selected when encoding (maps into 'string'
2816 when decoding). Needed to talk to some servers.
2818 Demo client can request simple element set names.
2820 Added Diagnostic Format encoders/decoders.
2822 Added simple Close handling to frontend server (no hooks for resource
2823 reporting yet), and demonstration client.
2825 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2827 --- 1.0b3 1995/08/24
2829 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2830 handled incorrectly when records were requested in the searchResponse. This
2831 will only affect you if you use the frontend-server.
2833 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2834 Test-client will ask for and print GRS1. Ztest will return dummy records
2837 Added Explain encoders/decoders to the service-level API. Untested.
2839 Added Extended Services: Item Order encoders and decoders to the Service-
2840 level API. Untested. We could use a recent copy of the pertinent bits
2841 of the ILL protocol to add those bits.
2843 Added diagnostic format 1 encoders/decoders to the service-level API.
2846 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2847 odr_cons.c, which causes a more correct output.
2849 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2850 was always set to 0 when no records were requested in the searchRequest.
2852 * Added better external-handling. This shouldn't harm old code that
2853 *encodes* externals. It can break code that looks for a
2854 'single-ASN1-type' representation, since those types that are known
2855 are now decoded immediately. Look at the SUTRS sample code in
2856 seshigh.c and client.c. Documentation updated.
2858 Handling of structured records in bend_fetchresponse. Length -1 marks
2859 structured record, type is deduced from format field.
2861 --- 1.0b2 1995/06/27
2862 Fairly quick maintenance release to add SUTRS support.
2864 Fixed handling of SUTRS records in the demonstration client.
2866 * Added format field to the bend_fetchrequest and bend_fetchresponce
2867 structures of the backend API (frontend server). When the record is
2868 returned, the value of the format field is mapped to an OID. The
2869 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2870 of the record. The special value VAL_NONE in the bend_request means
2871 that no specific format was requested by the client. Documentation
2872 updated accordingly. Test server (ztest) will return a fixed dummy
2873 SUTRS record if your client requests SUTRS.
2875 Documentation updated accordingly.
2877 You can now set external libraries and RANLIB support in the top-level
2881 First public release.
