3 Update yaz.spec to operate on both SLES11 / Centos 5.5.
5 RPM: Release includes 'indexdata' name. Use indexdata in release name so
6 this package can be distinguished from other vendors.
8 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
9 as determined by configure
11 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
13 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
14 returns no error and no record, the present request is considered
15 partial (only a subset of the records could be returned by backend), and
16 so it is appropriate to set Present Status to partial-4.
20 Move yaz-config man pages to section 1.
22 More documentation about SOLR.
24 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
25 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
26 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
27 peers on some Linux systems. However, in general that does not work
28 so YAZ can not rely on that to work. Debian changed behavior in this
29 respect from Debian lenny to Debian squeeze (still testing as of Oct
31 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
33 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
37 Fix yaz-config output: echo_source not set correctly by configure.
41 SOLR WebService support for yaz-client and ZOOM.
43 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
47 Z39.50 facet support. Facet specifications are passed for search in
48 other-information with ASN.1 as defined in facet.asn and OID
49 .10.1000.81.5 . Facets are expressed as an Attribute list as known
50 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
51 3 is limit (number of entries to get in response). yaz-ztest returns
52 dummy facets if a client asks for them.
56 CCL fixes: bug 2895 and bug 3539.
58 GR1-display: add comma in display - was removed by mistake in
61 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
63 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
67 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
68 result set from a connection. The result set will be on its own
69 thereafter; no operations on it will perform retrievals from a target.
70 Only cached copies are returned.
72 ZOOM C:fix case for HTTP servers responding with Connection:close.
73 Ensure that if there is a current task it is resumed (like fetching
74 more records in a result set) . Bug #3484.
76 PQF parser: use odr_atoi for Odr_int (not atoi)
78 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
79 values that contain any non-digits are treated as string attributes
80 (previously decoding only checked for leading character ([0-9]). PQF
81 encoding: attribute string values are not surrounded by double-quotes.
85 New utility for managing threads - thread_create.h.
87 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
88 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
89 but YAZ' implementation do.
91 Fixes for yaz_cond-functions on Windows 7.
93 DLL export more symbols.
95 zoomsh: show record do NOT render opac.
97 Remove *.la files from Debian and RPM packages.
101 Debian package libyaz-dev depends on libgnutls-dev again (was
102 removed in YAZ 4.0.6, but due to Libtool it is still needed
103 even though yaz-config do not list libgnutls libs).
105 ZOOM: Use only one WRBUF for returning string results for
106 ZOOM_resultset. Reduces memory usage for ZOOM in general.
108 ZOOM: ZOOM_connection do not use a shared pointer to
109 ZOOM_resultset after ZOOM_resultset is destructed by
110 user. Reverts to YAZ 4.0.4 behavior.
114 record-conv: fix problem with at least one XSL conversion -
115 due to probably incorrect usage of XML XSL documents.
119 Fix yaz-config for static mode and the use of SSL (gnutls).
123 Forward decl timeval struct in mutex.h and gettimeofday.h.
125 yaz-config: fix 'static' mode linking.
129 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
130 are wrappers for pthreads or Windows. For Windows these are put in
131 a separate DLL: yaz_cond4.
133 libyaz.la (whole source) is compiled with thread. If thread support
134 is enabled enabled, all source of YAZ is compiled with treading support.
135 This allows core utilities such as yaz_log to use thread facilities.
136 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
137 thread utilities. This commit moves mutex utilities (mutex.c) from
138 libyaz_server.la to libyaz.la.
140 yaz-json-parse displays leading text until error.
144 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
145 patch from Giannis Kosmas.
147 SRU: no longer URL encode SRU database. The URL for an SRU server is
148 a URL and such is alreeady encoded - at least when given with leading
149 http:// or https://. This reverts behavior to YAZ 3.0.50.
151 Support for new MARC XML notation TurboMARC which like MARCXML is a
152 complete representation of MARC/ISO2709.. This one, however, is more
153 compact and allows for faster processing with XSLT. TurboMARC can be
154 used in the marcdisp.h API, from the yaz-marcdump utility and from
157 yaz-ztest can be configured - via the database - to perform certain
158 delays when it performs operations search, present and single record
159 fetch. This allows testers to make yaz-ztest act as a real or even slow
160 Z39.50 server. Refer to the yaz-ztest man pages for details.
164 wrbuf_destroy allows NULL WRBUF passed to it.
166 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
168 Add ZOOM_connection_close.
170 No fixed size buffers for ZOOM shell - bug #3257.
172 tstodr: make it work on s390 platform.
174 New icu iterator-functions. The new icu_iter-functions makes it possible
175 to use ICU chains from many threads.
177 yaz-client: better syntax check for show command.
181 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
184 New simple local-file XML include facility which allows file glob-patterns.
185 Refer to yaz/xml_include.h.
187 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
190 ZOOM_record_get supports new parameter "format" which makes it format XML
193 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
194 JSONText in ECMA-262) is JSONValue, not JSONObject.
198 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
199 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
201 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
202 POSIX/Unix builds .so with major version 4.
204 Remove old LOG_-defines from log.h. They have been obsolete and
205 undefined by default for the last 5 years.
207 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
209 GFS: Remove socket (int *fd) from search_rr handler. The socket
210 descriptor ptr is a facility that allowed a search handler to supply
211 a socket which would serve as a callback - when search was complete.
212 This facility has now been in use for years.
214 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
215 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
216 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
217 returns 'const char *' rather than 'char *. The returned string is
218 read-only and should not be modified by applications. COMSTACK cs_close is
219 now a void function - it no longer returns int. No applications check for
220 the value and the implementations has always returned 0.
222 ZOOM: use size_t for scan hit counts and str size. Functions
223 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
224 occ (hit count) and len (string length) are now of type size_t pointer
225 rather than int pointer. This is to be able to represent large hit counts
226 and to also just to use the proper type for string length (strlen result).
228 New JSON parser. Refer to include/yaz/json.h .
230 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
231 Used to be int in some cases. Many wrbuf_-functions used to return an int
232 indicating some length.. These return values were never used. And so they
235 ODR: odr_malloc, odr_total now takes size_t for size.
237 clone_z_type: fix leak; occurred for encoding failures.
239 --- 3.0.52 2009/12/03
241 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
242 bug was introduced in 3.0.51.
244 --- 3.0.51 2009/12/02
246 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
248 tcpip comstack: fix leak for getaddrinfo.
250 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
251 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
252 Decoding of SRU "path" database is performed by private function
253 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
254 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
256 yaz-client: honor base command for SRU. Change when database setting
257 is applied for SRU and ensure it is kept when a connection is reset.
258 Change also the way errors are displayed or SRU (decoding of packages).
260 --- 3.0.50 2009/11/02
262 Add support for extra request / response data for SRU codecs and GFS.
263 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
264 for extra data response buffer and length. For the GFS, both request
265 and response data (XML) is carried in extra_args and extra_response_data
266 for the search handler. Patch by Ko van der Sloot.
268 ZOOM: For queries that cannot be converted to the specified rpnCharset,
269 ZOOM now returns a diagnostic on the client-side ('invalid query' /
270 10010). This fixes bug #2113.
272 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
273 cmdfile included a 'quit' command that would result in a memory violation.
275 --- 3.0.49 2009/10/01
277 Make a number of functions defined in xmlquery.c static. These have
278 never been declared in a public header file (yaz/xmlquery.h) and was
279 made public by mistake.
281 Improve speed of character conversions (iconv utilities). This makes
282 conversions from MARC-8 faster.
284 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
285 unless type desired is "raw". This will prevent type "xml" from
286 returning ISO2709 .. Which obviously can not be XML parsed.
288 Fix memory leak in ZOOM that would occur if option apdulog was used
289 on a re-used connection.
291 Frontend server logs HTTP requests.
293 Frontend server now sends Z39.50 close when it times out (sesssion has
294 been idle for too long). Versions 2.0.30 and earlier also sent close.
295 But due to a mistake this was disabled in all versions after that, i.e.
296 the server would just close the socket immediately.
298 yaz-client emits a better message when receiving an unrecognised
299 userInformationField.
301 Skip zero-length subfields when decoding ISO2709. This rare case happens
302 if a record has two FS characters in a sequence. Without this patch
303 there would be a reference beyond char array in using_code_len fragments
306 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
308 --- 3.0.48 2009/08/28
310 The show command offered by the zoomsh command now takes a 3d optional
311 parameter type which is what is passed to ZOOM_record. If the type
312 argument is omitted, "render" is used.
314 RPN to CQL conv may use USE string attributes (bug #2978).
316 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
318 --- 3.0.47 2009/07/08
320 Function yaz_xml2query allows a diagnostic element in the PQF XML
321 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
322 code and additional info respectively.
324 The BER BOOLEAN is now the integral type Odr_bool which still happens
325 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
326 typedef'd to Odr_int. This is still an integral 'int', but it may be
327 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
328 ASN-1 compiler as well as programs has been updated to use the new types.
330 --- 3.0.46 2009/06/08
332 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
333 only the bibliographic record was rendered. For type=opac, an OPAC
334 record is only returned if it is present.
336 iconv: small fix for encoding of advancegreek.
338 yaz-client: avoid double display of SRU/SRW records (bug #2798).
340 yaz-client: option auto_reconnect=on really reconnects.
342 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
344 server: avoid null ptr ref for for yaz_poll errors.
346 build: fix RPM build for RHEL 5.3.
348 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
350 --- 3.0.45 2009/03/31
352 Fixed bug #2709: TCP connect returns Invalid argument.
354 Fixed compilation for mingw.
356 Honor charset for raw records (ZOOM_record_get).
358 Fixed use of errno for threaded mode that was seen on Solaris 10.
360 Fixed argument passing with blanks in value for Windows Service.
362 Disable YAZ' own log rotate by default (no 1 GB limit).
363 The variable l_max_size which specifies the log file limit is set to 0
364 (DISABLED): This is due to the fact that YAZ is most often deployed using
365 logrotate. Also YAZ can not perform log rotate because of unsufficient
366 permissions (setuid).
368 --- 3.0.44 2009/02/17
370 List supported encodings in man page for yaz-iconv.
372 Fixed missing SSL libs for --libs output
374 Re-established OID record syntax application-xml. Nobody should use it
375 but we don't want to change soname because of this symbol being absent.
377 --- 3.0.42 2009/02/02
379 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
381 Added member named_result_sets for init handler struct for the GFS. This
382 allows a server to disable named result sets.
384 Removed OID record syntax application-xml.
386 Added support for rule-based transliterator for ICU wrapper of YAZ.
388 Fixed bug #1902: yaz-icu XML output.
390 Make YAZ checks Emacs friendly.
392 BITSTRING value shows value. Bug #2346.
394 ISO2709 decoding: skip control characters from indicator data.
396 Omit sort key by default in yaz-icu's output.
398 Allow combined single char options (again) for YAZ' options function.
400 Utility yaz-marcdump got option to display YAZ version (-V).
402 Allow YAZ to use ICU 3.4.
404 Added new ICU test case which illustrates removal of diacritics.
406 --- 3.0.41 2008/12/29
408 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
410 --- 3.0.40 2008/12/29
412 For configure, using option --without-xml2 also disables Libxslt/Libexslt
415 Fixed bug #2352: yaz-marcdump crashes for certain record.
417 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
419 Added support for Danmarc2 to UTF-8 conversion.
421 Added support for ISO5426 to UTF-8 conversion.
423 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
424 implementation version.
426 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
428 --- 3.0.38 2008/11/10
430 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
431 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
433 ZOOM C now interprets databaseName option for ZOOM connection as path
436 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
438 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
440 Dummy Libxml2 types no longer defined in headers of YAZ'.
442 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
445 --- 3.0.36 2008/09/26
447 Various ODR chapter fixes.
449 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
451 Added missing source for Windows compilation, mutex.c.
453 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
455 For SRU connections in ZOOM all records up to "count" are now fetched.
457 Fixed crash in generic frontend server (and yaz-ztest) which occurred
458 in Windows due to bad error handling for Libxml2.
460 Added facility for sending arbitrary records (ASN.1 any) using
461 ZOOM C's Extended service update. Patch by Sam Reynolds.
463 New options for ZOOM C's connection, logapdu which makes ZOOM log
466 --- 3.0.34 2008/06/18
468 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
470 --- 3.0.32 2008/06/12
472 Fixed memory violation that could occur when decoding UTF-8. This bug
473 was only present in 3.0.30 of YAZ.
475 --- 3.0.30 2008/06/06
477 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
478 GNU TLS is used by default (if found).
480 yaz-ztest returns OPAC records if a client asks for OPAC.
482 Improved speed of MARC-8 encoding.
484 Added support for lossy and loss-less MARC-8 encoding.
486 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
488 Added new Windows Service wrapper (sc).
490 yaz-client's itemorder command may now send a file.
492 Fixed yaz-marcdump to allow the use of NS prefix for record element.
494 Added new function yaz_log_xml_errors.
496 Allow (but warn) unknown XML attributes in MARCXML parsing.
498 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
500 The UTF-8 to MARC-8 conversion now uses a different set of characters
501 for Greek symbols. Bug #2120.
503 --- 3.0.26 2008/02/21
505 Added yaz_daemon (daemon.h).
507 Fixed bug #2068: pkg-config trouble
509 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
511 --- 3.0.24 2008/01/28
513 Document --with-xml2 option.
515 Added OPAC XML XSD (etc/opacxml.xsd).
517 Allow glob mask for name attribute in retrieval element for the
518 generic frontend server's retrieval facility.
520 Changed yaz_poll_poll to return yaz_poll_except for all returned events
521 except POLLIN/POLLOUT.
523 Fixed error handling in cs_listen. Bug #2037.
525 --- 3.0.22 2008/01/20
527 Fixed version in yaz/yaz-version.h.
529 Fixed bug #2027: Crash when closing connection.
531 Changed configure so that ICU support is only enabled if only ICU
532 and Libxml2 is available (because the ICU chain is XML based).
534 --- 3.0.20 2008/01/15
536 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
537 is built. Only this DLL depends on the ICU runtime.
539 yaz-ziffy is no longer part of YAZ. It is distributed separately by
540 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
542 Changed license of CCL module to 'Revised BSD'. After consultation with
543 remaining members of the original EUROPAGATE consortium, we are re-issuing
544 the CCL module without a separate license. The software was developed by
545 Index Data as part of a research project. The special license was included
546 to help feed usage information back to the project consortium to support
547 project evaluation. At this time, the project consortium has long-since
548 disbanded, and the majority of the original principals have retired. At the
549 same time, we have significantly modified the software during the following
550 years, to the point where very practically no original code remains. To
551 simplify re-use of the software, we have contacted those members of the
552 consortium who could be reached, and agreed to re-issue the module as a
553 proper part of the YAZ package.
555 Tcl scripts uses /usr/bin/tclsh as preferred shell.
557 CQL closer to being version 1.2 compliant. CQL also allows free-form
558 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
561 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
562 bug could make Extended services handling crash in the ZOOM layer. This
563 bug was only present in YAZ 3.0.18.
565 --- 3.0.18 2007/12/19
567 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
570 yaz-marcdump reads and writes collection wrapped records.
572 Handle OPAC for record conversion module.
574 Fixes for ICU wrapper.
576 Allow ICU libs to be controlled with --with-icu .
578 --- 3.0.16 2007/11/12
580 Added yaz_poll which is a wrapper for select/poll. When poll is available
581 and non-buggy, it is used, by yaz_poll . This allows more than 1024
582 sockets to be in use.
584 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
585 functionality through an XML based configuration (ICU chain). This system
586 is useful for search facilities such as Pazpar2 and Zebra that needs to
587 perform tokenization of indexed material. The ICU code in a separate
588 library libyaz3_icu.a.
590 Added HTTP tunnel facility for COMSTACK, bug #1752.
591 This is a facility that allows a Web proxy, such as squid, to tunnel
592 Z39.50 traffic. This facility is "transparent" to must applications
593 using YAZ. It's enabled by using pseudo transport connect: followed by
594 the proxy address, followed by command, then follwed by he regular
595 "virtual" addresss. For example,
596 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
598 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
600 --- 3.0.14 2007/09/21
602 Fixed bad memory reference in ZOOM_record - cuased by member not being
603 initialized. This was a problem only in YAZ 3.0.12.
605 Fixed bug in conversion from MARC to XML: Non-XML characters in control
606 fields were not removed.
608 Changed the way C code is generated from codetables.xml. Made a MARC-8
609 conversion trie for each characterSet section rather than codeTable.
610 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
611 of codetables.xml from Larry Dixson, LOC. Bug #1464.
613 --- 3.0.12 2007/09/12
615 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
616 from ZOOM_record_error).
618 ZOOM C function ZOOM_record_get returns record schema for type="schema".
620 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
622 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
624 Better SRW-to-Bib-1 diagnostic mapping.
626 ZOOM C and yaz-client announces SRU version 1.2 by default.
628 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
631 Fixed in yaz_sru_decode to allow other version than 1.1.
633 --- 3.0.10 2007/08/22
635 Added support for SRU scan for ZOOM.
637 Added support for the use of the older versions or Extended Service
638 Update in ZOOM. To faciliate this, an option "updateVersion" may be
639 set to the version , 1=first, 2=second, 3=third. The third version is
640 what ZOOM C has used so far. And that, obviously, is the default.
642 Added support for CCL queries in Z39.50 queries sent to the GFS (and
643 therefore in Zebra and in SimpleServer-based applications). The new
644 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
645 qualifier file used to transform incoming CCL queries into Type-1 RPN,
646 which is passed into the back-end search callback function.
648 Added support for HTTP Basic authentication in clients: the SRU/W
649 codec encodes the username/password elements of the PDU structure
650 appropriately, and these may be set using the "user" and "password"
651 options in ZOOM-C applications (the same options that are used for
652 Z39.50 authentication).
656 Fixed bug #1208: SSL appears to be broken in ZOOM.
658 Fixed bug #1206: Libxml2 include path weirdness.
660 Added oid_name_to_dotstring.
662 Allow elementSetName to be specified for ZOOM C record update.
664 Allow waitAction to be specified for ZOOM C based for Extended Services.
666 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
667 syntax OID. Bug introduced in YAZ 3 series.
669 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
673 Fixed bug #1157: yaz-client does not read .yazclientrc from current
674 directory. yaz-client now reads commands from file given by option -f
675 if specified; then tries to read .yazclientrc in current directory.
676 Failing that, it reads .yazclientrc from user's home directory.
678 Added support for correlationInfo Note and ID for Record Update via
681 Added yaz-client command querycharset which specifies character set for
682 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
683 (termListAndStartPoint).
685 Charset ISO5428:1984 is an alias for ISO5428-1984.
687 Implemented a way to perform scan in a result set using Z39.50. This
688 is achieved by attaching the result set name in the characterInfo
689 (type InternationalString) of OtherInformation in the Scan Request PDU.
690 The result set is identified in the otherinformation by the new OID:
691 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
692 This allows for scan in result set and faceted search . Zebra did some
693 of this in the APT term using attribute type 8 and value being result
694 set. Using the OtherInformation approach for this is cleaner and easier
695 to work with in proxies and the like. This facility can be used in
696 yaz-client using new command setscan which takes a result set as first
697 argument, start position (APT) as second.
699 Changed decoding of SRU XML packed records to deal with servers that
700 have recordData with XML data with multiple root nodes. Also make
701 comparison for recordPacking case insensitive. Again, one server
702 returns "XML" where others return "xml".
704 For SRU responses allow Content-Type application/xml as well as text/xml.
708 Fixed bug in character set conversion of BER strings. Bug introduced
713 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
715 For OID class, use oid_class consistently.
717 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
720 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
721 character set for bibliographic information interchange". By Giannis Kosmas.
723 Added documentation on new OID API.
727 Changes to generic frontend server interface: added new member
728 'query_charset' for bend_initrequest structure. A backend init handler
729 should set this member to its native character set for query terms.
730 When defined, the frontend server logic will announce this character set
731 to a client if the negotiationModel bit is set by the client. All server
732 implementors are encouraged to specify this. If a backend server does not
733 specify this a warning is issued using yaz_log(YLOG_WARN,..).
735 Added CCL utility to remove terms (stop words) from resulting RPN
736 tree. This is handled by functions with prefix ccl_stop_words_ .
738 New ZOOM C option, "rpnCharset", which allows client-side conversion of
739 terms in RPN queries.
741 Clean-up the CCL API. Moved some internal structures from ccl.h to
742 private header cclp.h. Changed ccl_parser_create so that a Bibset must
743 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
744 This is replaced by ccl_parser_find_str which takes a string instead.
746 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
747 libyaz.la is the core of YAZ except the generic frontend server and
748 does not depend on POSIX threads anymore. libyaz_server.la is the
749 generic frontend server facilities and uses POSIX thread functionality
750 if available. The libyaz.la no longer depends on POSIX threads because
751 the number of global structures is limited. NMEM no longer re-uses blocks
752 between threads ; it simply free's memory immediately but allocates in
753 "large" chunks as usual. We don't expect any performance penalties
754 because of this. The yaz_log system is still using a global log_level so
755 caution must be taken when modifying it with yaz_log_init_.. +
756 yaz_log_mask_str. This, however, should not cause any trouble because
757 these functions are called during initialization of application code
758 anyway. `yaz-config --libs server` returns libs for server applications;
759 `yaz-config --libs` returns libs for non-server applications.
761 New OID database - with public definitions in oid_db.h. Removed old OID
762 database including the head oid.h and definitions such as enum oid_value
763 and struct oident. The new OID database uses the same string names as
764 before but the 'protocol' is gone. There are now only two representations
765 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
766 converts from string to OID; functions with prefix yaz_oid_to_string
767 converts the other way.
769 Change to emit_term() in CQL-to-PQF query translation: when a term has
770 the /regexp relation modifier, do not process it for leading and
771 trailing "^" and "*", which have quite different meanings in regular
774 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
775 write handlers no longer carries a 'last' parameter. This will make
776 yaz_iconv flush "less" characters. A flush is performed by call to
777 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
779 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
780 removed, because function yaz_query_to_wrbuf does the same.
782 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
783 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
785 Deprecated MARC utility functions removed.
787 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
790 Branch split: YAZ_2_1_55_branch
792 --- 2.1.54 2007/03/16
794 Fix to ZOOM-C so that transparent reconnection is properly handled on
795 connections that are in asynchronous mode.
797 Fixed compilation on OpenBSD 4.0.
799 Large strings in GRS-1 records are now properly displayed in yaz-client.
801 Added character conversion support for "advancegreek"; based on patch from
804 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
805 sequence is met. Before the error was not set so it would be unknown.
807 Adjust yaz-marcdump MARC reader so that it skips until record separator
810 --- 2.1.52 2007/03/07
812 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
813 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
814 fd_set structure used as a bitmask for the FDs to be selected on.
816 Using ACX_PTHREAD macro to check for POSIX threads.
818 Fixed have-vsnprintf check.
820 --- 2.1.50 2007/02/23
822 Fixes for configure on BSD. Bug #900.
824 Added snprintf/vsnprintf wrappers for systems that don't have
825 limits (heavens forbid).
827 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
828 created before all previous tasks were completed and removed from the
829 task queue, the new task could be removed by a mistake.
831 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
833 Implemented pass-through CQL-to-PQF conversions. Bug #861.
835 Fixed bug #832: Problem with MARC/charset in yaz-client.
837 Fixed bug #668: save command line history for yaz-client.
839 Fixed bug #830: pkg-config support.
841 --- 2.1.48 2007/01/23
843 Extended ZOOM result set options with two options that may be read by
844 a client: resultSetStatus and presentStatus with values as specified for
846 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
848 Fixed bug #827: Using SSL fails on Debian etch.
850 Fixed bug #826: Weird looking chars for set of MARC records.
852 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
853 that is treated as an ItemOrder with itemRequest being an XML document
854 external. The value of "doc" is the content.
856 Extended the GFS search facility. New member of bend_search_rr
857 'estimated_hit_count' signals that hits is known to be an estmate
858 (higher or lower than real hit count). New member 'partial_resultset'
859 signals that the search was partial (hit count is lower or equal than
860 real hit count). For Z39.50, the information is stored in resultSetStatus
861 member of SearchResponse APDU. For SRU, the information is signalled
862 via SRU diagnostic 59: "Result set created with valid partial results
865 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
867 --- 2.1.46 2007/01/13
869 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
871 Added ZOOM_connection_peek_event.
873 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
874 the following new functions:
875 ZOOM_event_nonblock, ZOOM_connection_process,
876 ZOOM_connection_get_{socket,mask,timeout},
877 ZOOM_connection_fire_event_{timeout,socket}.
878 The existing blocking event handler, ZOOM_event, is a wrapper for the
879 + blocking ZOOM_event_sys_{poll,select}.
881 Implemented function ccl_xml_config which parses XML version of CCL
882 configuration (bug #798).
884 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
886 Added timings utility (yaz/timing.h)
888 --- 2.1.44 2007/01/03
890 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
893 Fixed bug #779: Rotation of apdu.log fails.
895 Fixed for character set conversions:
896 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
897 Honor G1 set in MARC-8 decoding.
899 --- 2.1.42 2006/12/17
901 Fixed bug #775: char conversion does not handle Alternative UTF-8
904 Implemented function yaz_marc_read_line which parses MARC line format
905 records. There is a wealth of formats out there. So far, this function
906 reads line records produced by yaz_marc_write_line.
908 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
909 more generic and easier to remember(!) options: -i format and -o format
910 which specifies input format and output format respectively - where
911 format is one of "marc", "marcxml", "line", "marcxchange".
913 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
914 does not print anything except warnings for records.
916 For yaz-marcdump, added support for MARC split into files (-s) with a given
919 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
920 spec, at http://www.loc.gov/standards/sru/record-update/
921 This has changed the binary layout of the following structs:
922 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
923 bend_update_rr . Patch by Ko van der Sloot.
925 Added GFS utility function bend_assoc_is_alive which returns 1 if
926 association is still alive (client is connected); 0 otherwise (client
927 closed connection). This allows busy servers to stop working for
930 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
931 been a separate piece of software. This version of ziffy has been modified
932 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
934 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
936 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
937 Client code may now interrogate options such as "init_opt_sort" to
938 find out whether the server claims to support various options.
940 --- 2.1.40 2006/11/27
942 Added utilities yaz_{set,get}_esn to set/get element set name from
945 Removed the build of libyazthread.la. The libyaz.so is the threaded version
946 of YAZ and has been so since YAZ 2.1.10.
948 Implemented ZOOM_record_error which returns error information for
949 record (surrogate diagnostic).
951 --- 2.1.38 2006/10/31
953 Updates for SRU Update by Ko van der Sloot:
954 1. Changed name from "operation" to "action"
955 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
956 versions in the code, marked as 'backward compatible'.
957 3. Added diagnostics for SRU Update.
959 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
961 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
963 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
965 For GFS, fixed problem with SRU diagnostic 'First record position out of
966 range' being issued for 0 hits.
968 zoomtst10 part of Windows Build.
970 --- 2.1.36 2006/10/13
972 Implemented yaz_filepath_comp which splits a path into file path
973 components (required by Zebra 2.0.3+).
975 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
976 BSD inspired license until now so this should not have any real impact on
977 anybody. See http://www.opensource.org/licenses/bsd-license.php
979 Fixed bug #687: Missing log lines.
981 Fixed bug #678: CQL to PQF translation does not preserve double-quote
984 Fixed bug #689: SRU diagnostics to be added.
986 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
987 whether a connection is idle (no more work do do).
989 --- 2.1.34 2006/10/04
991 Change type of optval from long to int for invocation of setsockopt with
992 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
994 Added support for specifying the max log file size for the Generic
995 Frontend Server. The size is given with option -r.
997 --- 2.1.32 2006/09/21
999 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1001 --- 2.1.30 2006/09/17
1003 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1006 Fixed bug in Generic Frontend Server that could cause a server to stop
1007 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1009 For the generic frontend server, the maximum record size is used as maximum
1010 size of incoming packages (SRU + Z39.50). The value until was previously
1011 only used in Z39.50 Init negotiation and, later, in a session controlled
1012 sizes of records returned. This is controlled using -k option. It can be
1013 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1015 --- 2.1.28 2006/09/04
1017 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1020 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1022 New option for yaz-marcdump -lpos=value which allows setting a portion
1023 of MARC header to a certain value.
1025 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1027 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1028 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1030 --- 2.1.26 2006/08/15
1032 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1035 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1037 --- 2.1.24 2006/08/08
1039 Fixed MARC ISO2709 encoding routines to deal with character set
1042 Minor changes to GFS logging. Database included in search request log
1045 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1046 cached/multiple records.
1048 Shared libraries are built by default on Unix+configure.
1050 Changed cql2pqf transformation to use a different evaluation order. The
1051 new order is: always, relation, structure, position, truncation, index
1052 and relationModifier. Old order was: always, relation, relationModifier,
1053 structure, index, position, truncation. Note that the the latter ones
1054 override former ones for identical attributes.. The new scheme means that
1055 it is possible to override any existing attribute with a relationModifier.
1056 And also that it is possible to override everything for the index rule
1057 (except the ones listed in relationModifier). No order is perfect but this
1058 one, we believe, covers more real cases.. The "always" should have been
1059 called "default", since the attributes there can be overridden with all
1062 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1063 compilation phase, but also for yaz-config --cflags output. This allows
1064 us to have public headers with Libxml2 stuff in them . It should also,
1065 eventually, make Libxml2 checks redundant in packages using YAZ, such
1068 --- 2.1.22 2006/06/15
1070 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1071 stored in uri, message and details.. Previously diagnostics were stored
1072 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1073 compatibility.. but he's probably the only one affected, so.
1075 Added support for CCL, compiled on the client side, in ZOOM-C. This
1076 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1077 input; the resulting query objects can be used for for searching with
1078 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1080 YAZ' configure searches for OpenSSL by default.
1082 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1083 SL_CTX_use_certificate_file. See
1084 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1085 for more info. Thanks to Ko van der Sloot.
1087 --- 2.1.20 2006/06/02
1089 Bug #600: SRU GET, POST support for yaz-client. Introduced
1090 command 'sru' which selects method SOAP/GET/POST.
1092 Allow missingValueAction to be specified for the sortspec string -
1093 function yaz_sort_spec. By default, the missing value action is null.
1094 Use ! to specify "abort". Use = followed by stringvalue to specify default
1097 Ensured that Present-handler (if defined) is called in GFS before any call to
1098 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1099 searchRetrieve requests.
1101 Documentation for YAZ is now based on the Docbook XML/XSLT using
1102 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1103 is no longer depending on jade/openjade or docbook-to-man scripts.
1104 PDF is no longer part of the distribution - but can optionally be
1105 made using DSSSL/jadetex or FOP.
1107 Added retrieval handling support in Generic Frontend Server to support
1108 conversion between MARC/XML as well as XSLTtransforms. See
1109 etc/yazgfs.xml for an example.
1111 Added Authentication support to Generic Frontend Server in SRU
1112 mode. Authentication using HTTP Basic is supported, as is the use
1113 of 'x-username' and 'x-password' parameters in the request itself.
1115 Added support for a new character set MARC8s identical to MARC8 except
1116 that it converts combined characters to single Unicode characters in the
1117 Latin-1 range (when possible).
1119 --- 2.1.18 2006/04/24
1121 ASN.1 compiler 0.4: generates brief Doxygen file header for
1122 generated .h/.c files.
1124 Utility yaz_iconv now supports conversion to MARC-8.
1126 New facilities for the MARC module. The reading - and writing of
1127 content are separate methods for the yaz_marc_t handle. The following
1128 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1129 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1130 format). Write functions have prefix yaz_marc_write_.. The existing
1131 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1132 available. Removed support for OAI-MARC and simplexml (not the
1133 simplexml from PHP5).
1135 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1136 to be returned for this connection.
1138 --- 2.1.16 2006/03/31
1140 Allow multiple languages and charsets to be specified with
1141 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1142 negcharset iso-8859-1,utf-8
1144 Translation of proximity nodes from CQL into PQF now works.
1146 Moved to automake 1.8, 1.9.
1148 Added function yaz_log_set_handler which allows a log handler to be
1149 installed. This handler will be called for all log messages. Output
1150 to file is also produced; but that can be disabled by passing NULL
1151 fname to yaz_log_init_file.
1153 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1155 For SRW (including GFS), accept application/soap+xml as content-type
1158 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1159 produces NO stylesheet reference even if a default stylesheet is specified
1162 --- 2.1.14 2006/03/14
1164 Updated Windows package to include yazd.dll + yazd.lib for the
1165 Development component.
1167 If the environment variable YAZ_LOG is set, then it is used as a
1168 string indicating the default level of logging to use if not
1169 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1170 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1171 used as before. So, for example, to omit warnings from YAZ logging,
1172 export YAZ_LOG=-warn
1174 cql_transform() now map structure and other attributes before indexes,
1175 so that index-specific structures and other attributes can override
1176 defaults. So now a combination of mapping specifications such as:
1178 index.dc.date = 1=date-modified 4=5
1179 does the right thing.
1181 cql_transform() now also respects the "always" mapping specification,
1182 which establishes an initial set of attributes to be used for all
1183 terms except where overridden by more specific attributes associated
1184 with the index, relation or modifier.
1186 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1187 which mode to use; one of "post", "get" or "soap" (SRW, default).
1189 Fixes for yaz_iconv routines: changed trie-based character set conversions
1190 to use only non-negative values for bit fields due to Sun's C compiler not
1191 supporting negative values.
1193 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1194 sequences where not read correctly. Fix by Rustam Usmanov.
1196 Updated win/makefile to use options, settings which makes things
1197 compile with VS C 2005.
1199 --- 2.1.12 2006/02/01
1201 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1203 In ZOOM socket code, use select instead of poll on MacOSX.
1205 ZOOM-C now support client-side compilation of CQL into RPN that is
1206 sent to the server, enabling CQL to be used against all Z39.50
1207 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1208 ZOOM_query object, and submit it using ZOOM_connection_search().
1209 The CQL-to-RPN translation uses a configuration file, the name of
1210 which must be specified in the Connection's "cqlfile" option.
1212 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1213 function, which takes as its start-term parameter a ZOOM_query object
1214 (which may have had either CQL or RPN set into it).
1217 --- 2.1.10 2005/11/29
1219 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1220 GFS to support this as well. Backend handler, bend_srw_update, does the
1221 update work. Code contributed by Ko van der Sloot.
1223 Allow retrieval of Search Result-1 information in ZOOM by the use of
1224 options that are attached to a result set. ZOOM documentation updated
1227 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1228 UTF-8 conversion. Patch by Raj Patel.
1230 Added option -m to GFS to control formatting of timestamps in log file.
1232 Added 'exit' as synonym for 'quit' in yaz-client
1234 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1235 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1236 for the new members. Patch by Ko van der Sloot.
1238 Added support for SRU POST. It is supported for content-type
1239 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1241 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1242 Instead make the library libyaz.la multi-threaded. Threading as a whole
1243 can still be disabled by configure option --disable-threads. Previosly,
1244 with older GLIBCs there were problems with MT libs under Apache. This
1245 has now been fixed a long time ago.
1247 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1250 CQL module modified to be case insensitive for relations/indexes/operations.
1252 Fixed bug in CQL transform code: incorrect value relationModifieder
1255 Added 'show all' command for yaz-client which retrieves all results
1258 Added new yaz-client, xmles, which takes a (private) OID and
1259 a document to be sent as an extended service request.
1261 Describe new yaz-client commands wait_response and set_auto_wait.
1263 Increase TCP/IP listener backlog from 3 (which I am guessing was
1264 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1265 that the socket will queue as many incoming connections as it's able
1266 to handle ongoing connections. In other words, it will never now
1267 refuse a connection that it would be able to handle merely because
1268 it's not got around to accepting() enough of the pending connections
1269 yet. This is the behaviour anyway under Linux, where the listen()
1270 argument is ignored; but not under BSD and on systems such as
1271 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1272 YAZ-based servers should now be uniform across operating systems in
1275 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1276 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1277 This allows yaz-marcdump to read large MARC batches (>2 GB).
1279 Modified all YAZ source files - except the source which is auto-generated
1280 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1283 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1284 corresponding to the existing *_setl() function. These allow option
1285 values containing arbitrary valuues.
1287 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1288 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1289 except that it returns an indicator of whether or not the sort
1290 criterion was accepted (0 for OK, -1 for invalid).
1292 --- 2.1.8 2005/06/07
1294 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1295 MARC output rather than returning "new" buffer.
1297 yaz-client warns about unknown init options.
1299 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1301 --- 2.1.6 2005/05/24
1303 Added support for SRW sort in Generic Frontend Server. Patch
1304 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1305 sortKeys - or NULL if none is provided.
1307 Fixed bug #307: It was impossible to specify indefinite/no timeout
1308 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1311 Added support for multiple languages and charsets to be specified in
1312 ZOOM. Each charset/language is separated by a blank. If negotiation is
1313 in effect in init-response, Option
1314 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1315 Code based on patch by Vasiliy Osadchuk.
1317 Fixed bug #306: infinite recursion that occurred when calling
1318 yaz_log_level_init as the first call (before other log level or
1321 Fixed bug in scan handling in front end server: if preferred-Position-In-
1322 Response was non-present, a NULL pointer referece was performed.
1324 --- 2.1.4 2005/04/26
1326 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1327 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1328 now defined for all those error codes. So instead of putting 109 in
1329 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1330 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1332 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1335 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1337 Program yaz-client now exits and produces an error message if multiple
1338 Z39.50 servers are specified on the command line (none or one allowed
1341 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1344 --- 2.1.2 2005/03/16
1346 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1348 Fixed bug #272: Preserve spacing for CCL terms.
1350 --- 2.1.0 2005/03/14
1352 Added support for virtual hosts and multiple backend servers for
1353 the YAZ frontend server. The configution is XML based and
1354 support specificition of CQL to RPN mappings and explain information.
1355 See section "Virtual Hosts" in the YAZ manual.
1357 Extended OPAC display utility. OPAC display utility renders
1358 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1359 to supplement yaz_marc_decode_wrbuf.
1361 Fixed a bug in MARC decoder that could caused it to crash for some
1362 invalid MARC records. More diagnostics and warnings where added in
1363 XML output (warnings, etc are stored in comments).
1365 --- 2.0.34 2005/02/08
1367 Fixes for UNIX domain sockets. Bug #261.
1369 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1371 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1372 Added yaz_marc_subfield_str which defines subfield lead string which is
1373 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1374 yaz_marc_endline_str which defines end of fields string used in
1375 YAZ_MARC_LINE format. Default string is newline.
1377 Experimental support for MarcXChange. This format can be produced
1378 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1379 http://www.bs.dk/standards/MarcXchange.xsd
1381 Added yaz-client commands scansize that sets maximum number of
1382 entries to be returned by scan.
1384 --- 2.0.32 2005/01/11
1386 Added support for SRW scan in yaz-client and Generic Frontend Server.
1388 * Added whereInList member to SRW Scan Term.
1390 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1392 Fixed NMEM system to return aligned blocks on the smallest boundaries
1393 that are suitably aligned for all possible types on the particular
1394 architecture YAZ is being built for.
1396 --- 2.0.30 2005/01/04
1398 Fixed numerious warnings that was issued with newer versions of GCC.
1400 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1401 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1404 Make YAZ Generic Frontend Server slightly faster.
1406 Enhance (and reduce) logging for Generic Frontend Server.
1408 Revert YAZ log system so that it flushes every write operation
1409 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1411 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1412 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1413 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1414 will effectively disable old definitions.
1416 --- 2.0.28 2004/11/09
1418 Added yaz_log_time_format which specifies log format using
1421 Added yaz_log_module_level which returns mask for a module. Value
1422 is non-zero mask a if module is enabled; zero if disabled.
1424 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1425 in include/yaz/cql.h.
1427 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1429 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1431 Fixed bug #172: RPM builds does not enable SSL.
1433 Doxyfile.in part of dist. Doxyfile generated by configure.
1435 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1436 are given and the corresponding component does not exist.
1438 Extend CCL documentation in YAZ reference. Describe r=r.
1440 --- 2.0.26 2004/10/01
1442 Fixed MARC->MARCXML conversion to properly deal with
1443 fields, subfields, indicators having non-ASCII characters.
1445 Fixed MARC->MARCXML conversion so that ASCII control characters
1446 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1449 Added YAZ GFS support for conversion from Z39.50 surrogate
1450 diagnostics to SRW surrogate diagnostics.
1452 Bug fix: YAZ GFS did not return schema in explainResponse.
1454 --- 2.0.25 2004/09/30
1456 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1457 now converts recordSchema to elementSetName as well as schema URI.
1459 Fixed bug in COMSTACK that prevented HTTP request packages from being
1462 --- 2.0.24 2004/09/29
1464 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1465 does not require white-space before and after the dash in a range, e.g.
1466 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1469 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1470 due to new GCC removing "redundant" code.
1472 Added yaz-client commands scanpos and scanstep that sets preferred
1473 position and step-size for scan.
1475 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1477 Added CCL utility ccl_qual_buf which parses one or more CCL
1478 spec lines in a buffer.
1480 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1481 of name and value - ignoring empty lines and comments.
1483 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1485 Added odr_get_element_path which returns current element path for an
1486 ODR handle. This utility is useful in error handling or user-defined
1489 Added ODR_PRINT utility odr_set_stream which is is a more generic
1490 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1491 to a write function and pointer to close function. The close function - if
1492 non-NULL - will be called during odr_destroy.
1494 Fixed bug in CCL parser where truncation char was not removed from
1495 right side when truncation=both was in effect.
1497 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1500 --- 2.0.23 2004/08/11
1502 Fix buffer overrun in CQL parser when dealing with proximity (%).
1504 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1505 to UTF-8/UCS conversion is now only based on codetables.xml.
1507 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1509 --- 2.0.22 2004/08/06
1511 Add support for more "commit changes" in ZOOM (uses Extended Services).
1513 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1516 Yet another small fix for configure of SSL.
1518 --- 2.0.21 2004/05/14
1520 Fix SSL libs for configure when --with-openssl=DIR is given.
1522 --- 2.0.20 2004/05/10
1524 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1526 SSL comstack now uses yaz.pem certificate file on server side
1527 by default. Certificate filename can be configured by calling
1528 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1530 Fix bug regarding multiple calls to ZOOM_connection_connect.
1532 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1534 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1535 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1537 ZOOM now allows inspection of X509 peer certificate for verification.
1538 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1540 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1541 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1542 as "modular" but it simplifies things.
1544 Added cs_get_peer_certificate to that returns peer X509 PEM.
1546 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1547 NULL if SSL is unavailable.
1549 Documentation about MARC decoding tools.
1551 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1553 --- 2.0.19 2004/03/30
1555 Rename CHANGELOG to NEWS to follow GNU style packing.
1557 Fix bug with missing initialization of member in init_diagnostics.
1558 This bug affects threaded version of GFS server.
1560 --- 2.0.18 2004/03/20
1562 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1565 Ensure zlib.dll is packed with Windows install.
1567 --- 2.0.17 2004/03/17
1569 Fix encoding of xsd:string to use text instead of CDATA.
1571 Fix endless loop in CQL parser with unbalanced ".
1573 Use a more compact way to store MARC-8 conversion tables.
1575 --- 2.0.16 2004/03/16 Debian only
1577 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1580 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1585 --- 2.0.15 2004/03/01
1587 Another fix for decoding of XML packed records.
1589 --- 2.0.14 2004/02/25
1591 Fixes for Chunked encoding. White space not ignored after length spec.
1593 Update NS and use default NS for SRW diagnostic elements.
1595 --- 2.0.13 2004/02/23
1597 Implement ZOOM_resultset_cache_reset which resets record cache.
1599 Implement ZOOM_resultset_sort which sorts a result set.
1601 Implement chunked HTTP transfer.
1603 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1605 --- 2.0.12 2004/02/16
1607 Added member 'schema' to bend_explain_rr structure so that backend
1608 can specify explain record identifier. Defaults to Zeerex 2.0.
1610 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1612 --- 2.0.11 2004/02/16
1614 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1617 Added init command for yaz-client which sends "extra" init request.
1619 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1620 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1622 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1624 Make ZOOM error code for "invalid query".
1626 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1628 --- 2.0.10 2004/02/05
1630 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1633 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1635 Added option -p <file> to make Generic Frontend Server to write PID file.
1637 Added option -D to put Generic Frontend Server in background on its own.
1639 Make ZOOM C recognize option "password". If unset, "pass" is used
1640 (for backwards compatibility).
1642 Fixed a bug in Generic Frontend Server that could make it crash if a
1643 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1646 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1647 Must be issued before open, in order to be in effect.
1649 --- 2.0.9-6 2004/01/12 Debian/Windows
1651 Make the SRU server more picky WRT unknown params, etc.
1653 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1655 New YAZ client command, options, that sets Z39.50 options.
1657 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1658 options from a string of tokens (one token for each option bit).
1660 Update SRW diagnostic code messages.
1662 --- 2.0.9-5 2004/01/07 Debian/Windows
1664 Handle user defined stylesheet for SRW/SRU.
1666 --- 2.0.9-4 2004/01/06 Debian/Windows
1668 Fix bug in decoding of Content-Length.
1670 --- 2.0.9-3 2004/01/06 Debian/Windows
1672 Fix a bug with decoding of XML packed records.
1674 --- 2.0.9-2 2004/01/05 Debian only
1676 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1678 Fix bug in SRW/SRU diagnostics decoding.
1680 --- 2.0.9 2004/01/05
1682 Fixed bug in Generic Frontend Server which could drop records exceeding
1683 preferred message size. Reported and fixed by Irina Dijour.
1685 Fixed calculation of package size for structured records in Generic
1686 Frontend Server. Reported and fixed by Irina Dijour.
1688 Fixed namespace for SRW/SRU diagnostics.
1690 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1692 --- 2.0.8 2003/12/22
1694 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1695 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1698 CQL changes to reflect recent changes to the specification:
1699 * Documentation talks about context sets instead of index sets.
1700 * Documentation talks about indexes instead of qualifiers.
1701 * The CQL-to-PQF transformer's configuration file now uses
1702 "index.set.name = <attributes>" instead of the old form
1703 "qualifier.set.name = <attributes>". (Both forms are still
1704 understood but the latter is deprecated.)
1705 * CQL terms with no explicit index specified are now interpreted as
1706 cql.serverChoice instead of srw.serverChoice (which of course
1707 behaves exactly the same.)
1709 --- 2.0.7 2003/12/16
1711 MARC conversion can now generate ISO2709 output in another
1712 character set. yaz-marcdump uses this facility if you invoke it
1715 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1716 functions from there can be used from C++.
1718 --- 2.0.6 2003/12/04
1720 Frontend server now transfers memory from decoded packages to stream
1723 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1724 references to show up.
1726 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1727 the ZOOM Abstract API. The older names for the same options are still
1728 also supported for the benefit of old applications.
1730 ZOOM-C supports "implementationId" and "implementationVersion" options
1731 to go along with "implementationName". These allow the user code to
1732 specify identification strings to be sent to servers.
1733 Add OID for the new ExtLite attribute set.
1735 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1736 as requested/supplid by Ere Maijala <ere@atp.fi>
1738 For generic frontend server, reverse the order of
1739 "toolkit-supplied / application-supplied" strings sent as implementationId,
1740 Name and Version. Also, remove the spaces around the slash. This brings
1741 the GFS in line with the behaviour of ZOOM-C on the client side.
1743 Add function ZOOM_scanset_display_term.
1745 yaz-client shows scan displayTerm if present.
1747 Utility yaz-iconv is now installed by default along with the man page
1750 Extend configure check for OpenSSL to use pkg-config where available (such
1753 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1754 server to specify uid/gid/mask for socket using the format
1755 unix:[user=uid,][group=gid,][umask=mask,]file=path
1756 If file= is omitted the existing format is assumed, e.g.
1758 in which case the mask is 0666 (rw for everybody).
1760 Major restructure of YAZ source. All source in libyaz is in src directory.
1761 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1762 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1764 Added man page for utility yaz-marcdump (used to be called marcdump).
1765 yaz-marcdump is installed by 'make install'.
1767 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1768 of incoming package failed.
1770 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1772 Change prototype of odr_perror: add const to message string.
1774 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1776 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1777 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1778 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1779 DNS lookup. There should not be any compatibility problems with this
1780 assuming that blocking=1 or 0 is used.
1782 Fix bad reference in UNIX comstack in function cs_addrstr.
1784 Fix for compilation on AIX.
1786 The generic front-end server (server/seshigh.c) now supports returning
1787 Init diagnostics to the client in User-information-field, in
1788 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1791 --- 2.0.4 2003/09/04
1793 Allow any CQL relation (not just all,any,exact,scr).
1795 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1796 that features the same UI.
1798 Implemented command update0 in YAZ client which is equivalent to
1799 update but uses old of Ext Update ASN.1.
1801 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1802 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1803 Previously no OID was used for this info.
1805 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1806 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1807 returns 'malformed search term' otherwise.
1809 SortResponse member resultCount now set to NULL in sort handler of
1812 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1815 Add three new utility functions for translating OIDs between various
1816 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1817 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1818 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1819 char *oid_to_dotstring(const int *oid, char *oidbuf);
1820 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1822 Reverted modifications for ES Update definition for z_IU0Update
1823 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1824 is back to YAZ 2.0.2.
1826 String value attributes for CCL parser.
1828 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1829 which their FirstSearch server returns in Init responses, sometimes
1830 carrying useful diagnostic information when Init fails. This has the
1831 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1832 "z39.50/oclcui.asn", where its definition is somewhat different from
1833 what OCLC document on their web-site, as required to interoperate with
1836 Support for anonymous authentication in yaz-client. Use the command
1839 * Fix the OID of the Index Data-local "admin" Extended Service from
1840 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1841 the 1000, which indicates a locally-defined OID, was a mistake.
1843 --- 2.0.3 2003/06/20
1845 Fix CCL directive @case handling so that it affects string match for
1846 both CCL keywords and qualifiers.
1848 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1849 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1850 Decoder has been updated with ASN.1 changes as listed in
1851 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1852 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1853 z_IUUpdate, remains unchanged.
1855 ZOOM_record_get may now return a record in a specific character set.
1856 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1857 "from" is the character set of record as returned by target. "to" is
1858 the character set to be returned. If omitted, "to" is UTF-8.
1860 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1862 New ODR utility, odr_getelement, which returns name of element for
1863 which encoding/decoding failed.
1865 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1866 in cases where a required element was omitted.
1868 Bug fix: some MARC8 sequences were not converted.
1870 New ZOOM option "step" which specifies number of records to be
1871 retrieved in one chunk. Used in conjunction with "start" and "count".
1873 SRW support for yaz-client. Use scheme http: to use it, e.g.
1876 yaz-client no longer does (un)intelligent character set conversions
1877 by default. Can be enabled with charset and marc_charset commands.
1879 xmalloc trace fix for 64-bit systems such as DEC alpha.
1881 Solaris 2.6 compile fix.
1883 New function, cql_strerror() translates SRW error codes, as returned
1884 by cql_transform_error(), into human-readable English strings. Used
1885 in yaz-client diagnostics when appropriate.
1887 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1888 converts it into a type-1 query which is sent to the server. This
1889 makes CQL available for use with all Z-servers, as opposed to the tiny
1890 minority that can handle CQL queries themselves.
1892 --- 2.0.2 2003/04/28
1894 New Debian package layout similar to the Redhat Package layout.
1896 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1897 and search result respectively.
1899 --- 2.0.1 2003/04/25
1901 Redhat package is now several packages: libyaz (runtime libraries),
1902 libyaz-devel (development and documentation, and yaz (utility programs).
1903 Package spec file by Morten Bogeskov.
1905 New member 'schema' in struct bend_fetch_rr which the name of requested
1906 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1907 handler MAY set this to reflect the schema of the returned record.
1909 New member 'display_term' in struct scan_entry. GFS now sets member entries
1910 and allocates scan entries to be filled by user scan handler. In previous
1911 version, entries member was allocated by the scan handler. That still works,
1912 but the GFS will ignore member display_term - assuming it was NOT set by
1913 the handler. The fact that the GFS now allocates the entries both allows
1914 for new members and makes a scan handler easier to write.
1916 Fix CQL lex buffer overflow.
1918 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1919 SRU default recordPacking is string.
1921 SRU protocol support for frontend server.
1923 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1925 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1927 Added scan for the ZOOM shell (zoomsh).
1931 * String Identifers for Schemas (Amendment 5).
1932 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1933 Old definition for schema
1934 Odr_oid *schema; /* OPT */
1939 Z_InternationalString *uri;
1940 #define Z_Schema_oid 1
1941 #define Z_Schema_uri 2
1944 * resultCount parameter to Sort Response (Amendment 1).
1945 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1947 Support for SRW 1.0 over HTTP. This is an optional feature and
1948 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1951 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1952 on the same port. SRW SearchRetrieveRequests are mapped
1953 to bend_init,bend_search,bend_fetch,bend_close.
1955 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1957 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1958 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1960 ZOOM connections are SRW based if schem http is used for hostname
1961 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1962 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1964 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1965 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1966 distance=n, order=true/false, relation=le, prox unit=word. If
1967 n is omitted, distance 1 is used.
1969 Fixed problem with C compiler include path in wrong order.
1971 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1972 on Solaris. Patch from Ko van der Sloot.
1974 New MARC decode API. All new functions operate on a yaz_marc_t
1975 handle. The most important new functions are: yaz_marc_create,
1976 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1977 decode and destroy respectively. Decoder can produce formats
1978 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1979 include/yaz/marcdisp.h.
1981 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1982 to UTF-8, UCS-32, wchar_t or Latin-1.
1984 * Prototypes for yaz_iconv_-functions moved to separate header
1985 include/yaz/yaz-iconv.h.
1987 Make a few private functions 'static' in unix.c. This prevents
1988 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1990 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1991 are set when Init Response is received.
1993 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1994 but returns diagnostic set as well.
1996 New function yaz_strerror which is a portable wrapper for
1997 strerror/strerror_r/GetLastMessage.
1999 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2000 is returned for MARC. If type is "oai", then OAI MARC is returned.
2002 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2005 --- 1.9.2 2002/11/26
2007 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2009 Fix bad race conditions on SIGTERM and terminate gracefully in
2012 Move retrieval (data1) module to Zebra since nobody seems to be
2015 Add GRS-1 render for ZOOM using same format as yaz-client.
2017 --- 1.9.1 2002/10/05
2019 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2021 Fix broken ESpec handling in data1 module.
2023 SGML reader parses comments and makes them part of the data1 tree.
2025 Added several type casts so that YAZ compiles as C++ code.
2027 ZOOM didn't handle PDU encoding failures properly.
2029 Added more Bib-1 diagnostics (approved extensions).
2031 GNU configure: better check for iconv.
2033 More portable use of accept, getpeername. Check for socklen_t. Use
2034 int/size_t if socklen_t is not defined.
2038 PQF parser rejects bad queries - including those with extra
2039 characters in them. PQF parser used to silently ignore that.
2040 Cleaner API for PQF added, which allows you to get detailed
2041 error information for bad queries (see yaz/pquery.h).
2043 Fixed bug in ZOOM_record_get for type "database".
2045 Implemented mini iconv library supporting conversions between
2046 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2048 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2050 --- 1.8.9 2002/08/20
2052 Fixed ZOOM C record cache so that preferredRecordSyntax and
2053 elementSetName is used to check for already fetched records.
2055 --- 1.8.8 2002/08/02
2057 Added three members in bend_initrequest structure to facilitate
2058 character set negotiation.
2060 Fixed a bug in frontend server that could cause indefinite
2061 loops under rare conditions.
2063 Revised character set utilities (charneg.h) so that encoding
2064 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2066 For PQF, directive @term <type> sets term type for Scan/Search.
2067 Here <type> is general, string, numeric, null. The term type
2068 is inherited - just like @attr.
2070 New call odr_set_charset that sets character set conversion for
2071 international-strings on a ODR stream. Prototype is:
2072 int odr_set_charset(ODR o, const char *to, const char *from);
2073 The InternationalString is still represented as C string in YAZ
2074 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2075 won't). On the protocol level, you can use any encoding.
2077 Support for UNIX sockets in ZOOM.
2079 Solaris recv sometimes returns errno == ENOENT. It is treated as
2080 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2082 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2083 both client and server. Code by Morten Bogeskov.
2085 --- 1.8.7 2002/05/22
2087 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2088 that they can be used directly from Visual Basic. You must recompile
2089 your windows APP if you're using ZOOM.
2091 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2092 Commands "lang" and "charset" sets language and character set respectively.
2093 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2094 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2096 Attributes from multiple CCL fields may be OR'ed rather than merged
2097 using directive "@field or". Fields are still merged by default -
2098 equivalent to "@field merge".
2100 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2103 Fixed bug in zget for parameter ExtendedServicesResponse.
2107 --- 1.8.6 2002/03/25
2109 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2111 Client displays USR.1:SearchResult-1 (hits per term).
2113 Additional Search Info for search in Generic Frontend Server.
2115 Fixed CCL parsing of "field=s".
2117 WIN32 installer - using the excellent NSIS software from nullsoft.
2119 Fixed CCL parsing of "field = - <number>".
2121 Added function yaz_marc_decode that decodes MARC for line mode
2122 display or XML (similar to that used by JZKit).
2124 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2125 Z39.50. But ISO/ILL was, however.
2127 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2128 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2130 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2131 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2133 --- 1.8.5 2002/02/03
2135 New YAZ client features: Command completion and new commands:
2136 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2137 Code provided by Jacob Poulsen.
2139 New call oid_trav, that visits all registered OIDs via callback.
2141 Function ZOOM_record_get now returns const char pointer rather than
2142 void pointer. It saves a lot of type casts.
2144 For YAZ client, command "auth" now allows you to set authentication
2145 in IdPass style. It is enabled when three tokens are given - order
2146 is user, group and password.
2148 Fix memory leaks in MARC record handling for ZOOM.
2150 New option for YAZ client, -k <kilobytes> that sets
2151 maximum record size. Similar to -k option for generic frontend
2152 server and yaz-ztest.
2154 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2156 Prefix query parser reports "fail" when bad attribute set is given.
2158 Fix in MARC decoder. Proximity logging. Fix for attribute set
2159 in scan handler for server. Patches by Shigeru Ishida.
2161 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2164 Configure option --with-openssl=<dir> now works when a directory is
2165 specified. Patch provided by Morten Bogeskov.
2167 New option for YAZ client, -u <auth>, that sets authentication.
2169 ZOOM fix: error information was sometimes "missing", since error
2170 was cleared/reset too when it shouldn't.
2172 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2174 --- 1.8.4 2002/01/04
2176 Scan for ZOOM API. New object ZOOM_scanset. New functions
2177 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2178 ZOOM_scanset_destroy.
2180 New ZOOM function, ZOOM_connection_last_event, that returns type
2181 of last event (such as "receive data", "send data", "apdu received",
2184 New ZOOM option, schema, that specifies schema for retrieval.
2186 New CCL feature. Qualifiers can be aliases for one or more
2187 other qualifiers (if more than one is given, OR is used).
2189 ZOOM uses named result sets if target supports it.
2191 Two new YAZ client commands: . (dot, which sources a script of YAZ
2192 client commands), and ! (to execute shell command.). Implemented
2195 Working on Debian packages.
2197 --- 1.8.3 2001/11/19
2199 YAZ client enables named result sets only if target supports it.
2201 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2203 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2204 with key="host" to get same result.
2206 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2207 Function Z3950_resultset_record(s) returns references to records
2208 "owned" by resultset. To become owner use Z3950_record_clone.
2210 Function z_ext_record handles Extended Services. Thanks to
2213 --- 1.8.2 2001/11/12
2215 CCL Parser fix: ignore token comma when dealing with and-lists.
2217 Documentation updates for COMSTACK.
2219 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2220 Changed prototype Z3950_records. For some functions, int parameters
2221 were changed to size_t.
2223 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2226 New MARC decode/display function, marc_display_exl, which properly rejects
2227 non-ISO2709 records. YAZ client uses it.
2229 --- 1.8.1 2001/10/29
2231 Fix bug: local attribute set wasn't set correctly in PQF strings.
2235 * Old Z39.50 codecs no longer supported.
2237 Added ZOOM C binding. See http://zoom.z3950.org/
2239 Renamed states for COMSTACKs to avoid confusion with events.
2241 Implemented cs_look and proper cs_rcvconnect.
2243 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2245 Configure detects POSIX threads on OpenBSD.
2247 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2248 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2250 When error is returned from present handler, non-surrogate diagnostic
2251 is returned in present response (and fetch handler is no longer called).
2253 * Minor adjustments to pquery parser (PQF). Token characters may be
2254 escaped by using backslash (C-style).
2256 PQF parser allows string attribute values to be specified. For @attr,
2257 non-numeric characters after the equal-sign are treated as strings
2258 (e.g. @attr 9=title).
2260 CCL trunction character may be defined (@truncation in file)
2262 * function zget_ExtendedServicesRequest sets waitAction to
2263 waitIfPossible (was wait).
2265 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2268 CCL operator names may be set in field definition files (CCL_bibset).
2269 See ccl/bib1 for an example.
2271 Fixes in ASN.1 compiler for C++ compatibility.
2273 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2274 and "op_or" to avoid conflict with C++.
2276 Fixed problem with GNU readline detection on Redhat 7.0.
2278 Added step-size for Scan backend handler.
2280 Fixed bug that made the frontend server crash when no attribute
2281 set was specified for scan.
2283 Front-end server automatically switches to original working directory
2284 when installed as an NT service. Previously -w had to be specified to
2287 Added extended attributes for retrieval module (data1), so that data1
2288 records carry d1_readXML/SGML attributes. d1_read also supports
2289 null-data rules ( <tag/>)
2291 On UNIX when POSIX threads are available, a separate library libyazthread
2292 is created. Programmers should link with that library and the yaz library
2293 when using threads. The reason for the split was that some applications
2294 on Linux, such as Apache, doesn't work well when using shared objects that
2297 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2298 (or any frontend server) in SSL mode by specifying ssl: followed by
2299 address. Only tested on UNIX.
2301 Added feature for CCL module. Virtual structure s=al or s=ol generates
2302 and-list and or-list respectively instead of phrase search.
2306 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2307 log_mask_str. This was done to avoid name conflicts with other libraries
2308 (such as other PHP extensions).
2310 Added raw OID member for preferred record syntax (request_format_raw)
2311 and returned record syntax (output_format_raw) for backend fetch method.
2313 Config file yaz-config now accepts options so that it returns specific
2314 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2316 Shared library support for UNIX using GNU libtool.
2318 * Modified backend interface. Request/Response struct's replaced by
2319 one read/write C struct. For example bend_fetchrequest and
2320 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2321 Every handler - even search has to be registered in bend_init
2322 handler. This means that the YAZ library no longer refers to
2323 external functions and it makes it possible to make the whole
2324 thing a single DLL/SO.
2326 Added Segment handler for backend server.
2328 Added Zmbol/Zebra administrative functions to YAZ client.
2330 Threaded frontend server on UNIX (when POSIX Threads are available).
2331 Starting the server with option -T enables multi-threading.
2335 Added configure option --enable-comp/disable-comp to control use
2336 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2337 located in sub directory asn.
2339 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2340 in ${exec_prefix}/bin along with the other programs yaz-client and
2343 GNU automake used to maintain makefiles.
2345 Added several OID's.
2347 Changed retrieval module so that we can load records with no abstract
2348 syntax defined. Tagpaths in these records are fully composed of string
2351 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2355 On UNIX, the generated makefile now supports a proper 'make install'.
2356 The prefix can be set via GNU configure to set the install location
2357 (default is /usr/local).
2359 * YAZ programs client and ztest were renamed to yaz-client and
2360 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2361 locations, such as /usr/bin,/usr/local/bin,etc.
2363 * YAZ Header files were moved from include to include/yaz. YAZ Header
2364 files are referred to as include <yaz/log.h> rather than <log.h>.
2365 The YAZ include path (-I ..) is therefore the same as before. Programmers
2366 should update their #include statements or use -Ipath/include/yaz
2367 instead. The main motivation for doing this change is that YAZ header files
2368 can be installed in "standard" locations /usr/include,/usr/local/include
2369 without introducing conflicts, since ALL YAZ header files are stored
2370 in subdirectory yaz (under /usr/include for example).
2372 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2373 rather than project/workspace files. We switched because project files
2374 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2377 Changed name of logging function, logf, to yaz_log, to prevent name
2378 clash with some math-log functions. The YAZ header log.h defines logf
2379 to yaz_log (#define) so there should be no incompatibilities by this
2382 Added bend_start/bend_stop handlers for server. These handler are
2383 called on start/stop of server. For windows they are called whenever
2384 a service is started/stopped.
2386 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2387 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2388 in util/yc.tcl. The auto-generated C code structures are, in a few
2389 cases, incompatible with the old decoders. There are differences in the
2390 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2391 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2392 The preprocessor variable ASN_COMPILED is defined when the compiled
2393 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2394 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2395 wish to use the old encoders/decoders you can specify --disable-yc
2398 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2399 version so that it supports both new - and old version of DB Update
2401 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2402 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2403 change. The name parameter can be set to 0 in which no name is specified
2404 for the construction. The macros odr_implicit and odr_explicit sets name
2405 parameter to zero for the construction involved. New macros
2406 odr_implicit_tag and odr_explicit_tag are similar to the others,
2407 except that a name parameter is added. For programmers' that don't use
2408 ODR they probably only need to change the call to z_APDU and z_External.
2410 Added access control facility by interfacing the TCP wrapper library.
2411 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2412 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2413 name of the daemon and enables the access control as specified in
2414 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2416 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2417 den Dool <H.M.vdnDool@kub.nl>.
2419 Added reference ID parameter to most functions in server API - refer
2420 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2422 Changed name of ccl library to libccl.a (was ccl.a).
2424 Fixed bug in decoder for Explain (Category TargetInfo).
2426 Added support for GNU readline in client. Thanks to Jacob Poulsen
2427 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2429 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2430 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2431 IMPLEMENTATION! This change was made to the development version before
2432 the ZIG decided to retract the amendment. If any users MUST be
2433 compatible with the original Update definition, PLEASE CONTACT US, and
2434 we will include a separate definition corresponding to the old Update
2435 ES. Note that because of the change to the ASN.1 of the
2436 TaskPackageRecordStructure we cannot define a single structure that
2437 will support both versions.
2439 * Added const modifier to buffer parameter for some ODR/BER encoding
2440 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2441 completeWAIS, odr_dumpBER.
2443 Fixed bug in client.c which caused a crash when a scanResponse didn't
2444 contain positionOfTerm.
2446 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2447 * will cause an error in a client if a non-YAZ target sends both a
2448 * list of Scan entries and non-surrogate diagnostics.
2450 Retrieval module enhancements. Tag sets may be typed in the reference
2451 to it. From the .abs-file the "tagset" directive takes a third optional
2452 integer type for the tag set referenced. From a .tag-file the "include"
2453 directive takes a third optional type as well. The old "type" directive
2454 in the tag set itself is still recognized but acts as the default type
2457 Backend interface change. Individual Scan terms returned from bend_scan
2458 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2459 in include/backend.h.
2461 Retrieval module enhancements. Multiple tag sets and attribute sets may
2462 be specified in abstract syntax specs. Revised the error/warning for
2463 logging messages reported by the retrieval module when reading the
2466 Object Identifier system (oid_..) changed. The API is backwards
2467 compatible but the oid-routines now allocates new OID's when needed.
2468 Raw OID's may be specified in oid_getvalbyname.
2470 YAZ now uses GNU configure to generate Makefile(s).
2472 * Minor changes in some of the member names of DeleteResultSetRequest and
2473 DeleteResultSetResponse. See include/proto.h.
2475 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2476 and added member 'languages' in TargetInfo (which was missing).
2478 Changed the way attribute sets are handled in the retrieval
2479 module. These are now cached, just like the abstract syntaxes
2482 Changed YAZ so that it links with compiled ASN.1.
2484 Added Explain-schema definitions and mapping routines. The following
2485 Explain categories have been implemented: AttributeDetails,
2486 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2488 Fixed minor bug in Windows version of Server Library.
2490 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2492 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2494 Added EXTERNAL: UNIverse Resource Report (non-standard).
2496 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2497 ENUMERATED and SET OF.
2499 * Added 'const' to some of the char pointer arguments for the
2500 functions, data1_read_node, data1_getelementbytagname,
2501 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2504 Fixed bug in data1_insert_taggeddata - the last_child member of
2505 parent wasn't initialised.
2507 * Changed data1_read_record and data1_read_node so that the supplied
2508 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2509 doesn't refer to any parts of the "SGML"-buffer.
2511 Fixed bug in server library (Windows version of statserv_remove).
2513 * Changed code so that it compiles as C++. The type definition
2514 of Odr_fun which is a member of Odr_arm was changed. The result is,
2515 that an explicit typecast is needed for the fun pointer when
2516 using Odr_arm - as in:
2517 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2519 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2521 Implemented the new structured date and time definition as approved
2522 by the ZIG. Added schemaId element to the specificTag in Espec-1
2523 (also approved at the last ZIG). Thanks to RVDM.
2525 Added some Object identifiers (RVDM).
2527 Changed the Update Extended Service (RVDM).
2529 Added command "refid" to client which specifies referenceId for
2530 the following requests.
2532 Implemented extended service handling for server. See ztest.c
2533 for an example as well as backend.h. New handlers are registerd
2534 in the Init handler.
2536 * Changed interface for sort in server.
2538 Added new members to statserv_options_block. It allows a server
2539 to read options from another source than just the command line. Thanks
2540 to Charles Woodfield.
2542 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2543 renamed to zboolean. Some C++ compilers complained about the name.
2545 Minor changes to gils.abs. Added index 's' (sort) on title
2546 and date/time-last-modified.
2548 --- 1.4pl2 1998/1/30
2550 Fixed bug in server library regarding inetd mode (-i). This bug
2551 was introduced by release 1.4.
2553 --- 1.4pl1 1998/1/29
2555 Added sort facility in client and backend server interface.
2557 Fixed problem with dependencies in Makefile(s).
2559 Fixed bugs for encoders/decoders of extended services and
2562 Implemented sub-tree feature for schemas. Sub-trees are
2563 referenced in *.abs-files. See explain.abs for an example
2564 of the use of this feature.
2566 Modified bib1.att; local attributes for ANY didn't include
2567 ANY itself (only affects use of the retrieval module).
2569 Fixed bug in plain SGML reader in function data1_read_node:
2570 tags with prefix "var" was incorrectly interpreted as variants.
2572 Added feature "sub-schemas" to enable references to - and definitions
2573 of - group of elements.
2575 * Removed member parent from type data1_element (in data1.h).
2577 Implemented function odr_nullval() that returns the value of
2580 * Removed member num_children from data1_node (in data1.h).
2582 Made NT service interface part of the server library. The
2583 function statserv_main uses the NT service when required and
2584 calls the statserv_start / statserv_close routines.
2586 Routine zget_SearchRequest and zget_PresentRequest fills
2587 resultSetName/Id member with "default" instead of "Default".
2589 Fixed memory leak in server. Request queue member wasn't freed.
2591 Fixed nmem_exit so that memory is freed.
2595 Revised the CCL parser utility to be thread safe.
2597 Added function, oid_ent_to_oid, to replace the function
2598 oid_getoidbyent, which is not thread safe.
2600 * Added nmem_init and nmem_exit to initialize and release
2601 NMEM resources. Function nmem_init should be called once in the
2602 initial thread before NMEM/ODR is used. statserv.c and client.c
2603 have been changed accordingly. The change was necessary to make
2604 NMEM thread safe. The NMEM memory pool is shared amongst threads
2605 in a process. Unix-based applications will still work fine without
2608 Added NT Services interface for the the Z39.50 (statserv) Server.
2609 Refer to the ztest.c source on the usage.
2611 Windows 95/NT port using MSVC5.0. Project files are included in the
2614 * Defined new 'global' handle for the retrieval (data1) system. The
2615 new handled, data1_handle, describes the state of the data1 system.
2616 This handle is passed as first argument to virtually all
2617 data1 related routines. The functions data1_create and data1_destroy
2618 creates and destroys a data1 handle respectively.
2620 Added ODR encode stream member to all backend request structures
2621 init, search, scan etc. This stream should be used to allocate all
2622 memory used for the response when thread safe operation is needed.
2624 Changed the comstack utility, cs_addstr, to be thread safe. The
2625 returned hostname string returned by the function is now part the
2628 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2629 function. The cs_straddr takes a COMSTACK handle as argument, so this
2630 function must be used after cs_create and before bind/connect.
2631 This function is thread safe.
2633 Moved test server to 'ztest' directory - generic server code still
2634 in 'server' directory.
2636 Made prefix query (pquery.c) utility thread safe.
2638 Added new function modifier YAZ_EXPORT to 'export' public DLL
2639 functions when using windows (see include/yconfig.h).
2641 Added definitions to the OID database (util/oid.c) (RVDM).
2643 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2645 Added call to ccl_rpn_delete in client program.
2647 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2648 release of RPN structure.
2650 Added support for C++, headers uses extern "C" for public definitions.
2651 With input from RVDM.
2653 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2654 Thanks to Ronald van der Meer (RVDM).
2656 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2658 Added support for private extensions to the OID database
2659 (oid_setprivateoids()). Thanks to RVDM.
2661 Added optional, physical ANY (key replication)
2663 Fixed null-reference problem in GRS-1 output filter.
2665 Proximity operator added to Prefix Query Format (PQF).
2667 In test client command "base" accepts multiple databases.
2669 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2673 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2675 Smallish bug-fixes in the new encoders/decoders (explain).
2677 Bug fixed in DeleteRequest.
2679 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2681 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2683 Added SOIF syntax (using private OID for now) to retrieval module and client.
2685 Added Update extended service.
2687 Added SearchResult-1 additional info structure.
2689 Added optional CCL (ISO8777) interpreter as separate module. Available
2692 --- 1.2 1996/6/10 (1st anniversary release)
2694 Added Summary record syntax. Lightly tested.
2696 Added OPAC record syntax. Untested.
2698 Added ResourceReport service encoders/decoders. Untested.
2700 Fixed bug in z_Unit - wrong tagging on unitSystem.
2702 Fixed bug in the DiagRecs decoder.
2704 Added options for max PDU size and session timeout to frontend-server.
2706 Added documentation of query-language parsers and other supporting utilities.
2708 [frontend-server] Added Attribute set to the bend_scanrequest API.
2710 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2711 surrogate diagnostics were generated.
2713 [retrieval] Allow multiple local values for attribute.
2715 [retrieval] Allow multiple attributes per element in .abs files. index type.
2717 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2719 --- 1.1pl2 1996/4/10
2721 Minor changes, mostly specific to Zebra's requirements (retrieval)
2725 Repaired bug in frontend server when running multiple listening
2726 endpoints in dynamic mode.
2728 z_External() now won't break if a known, ASN.1 value comes encapsulated
2729 in an octet-string. The value will pass through unmodified in an Odr_oct.
2731 Added a bit of code to the demo client to decode & display
2732 ASN.1-structured records represented in the octet-aligned branch of
2733 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2735 Added z_ext_getentbyref() to the ASN module. Doc updated.
2737 * Completed the SCAN definition in the ASN module. This may break SCAN
2738 code based on older YAZ-versions at compile-time. The fix is easy -
2741 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2742 under the SCAN definition. Remember to initialize this, server-people.
2744 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2745 that this does not extend to ODR and ASN.
2747 Comstack allows insertion of established socket (primarily for
2748 inetd-operation of servers). Doc updated.
2750 Front-end server can now start from the inetd in TCP mode. Doc
2753 --- 1.0pl4 1996/1/24
2757 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2758 the rank and record number.
2760 Adjustments to the frontend server.
2762 Fixed diagnostic BER dumper. It ignored the file argument.
2766 Various changes to retrieval module.
2768 Changed the union discriminators of the protocol files from enums to
2769 ints paired with #defines.
2771 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2774 *Changed operator in the RPN structure to 'roperator', again to avoid a
2777 Fixed problems in Explain decoders/encoders.
2779 --- 1.0pl2 1995/12/6
2781 Memory bug in log module fixed.
2783 --- 1.0pl1 1995/12/5
2785 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2787 Bug in Explain DatabaseInfo module fixed.
2789 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2793 The shift to v1.0 signals that we now consider the *core* functionality
2794 of YAZ reasonably stable (the core being more or less equivalent to
2795 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2796 tested (Explain not at all - though that will happen soonish).
2798 Minor changes to code to support Windows port.
2800 Various minor changes after we're getting to use GRS-1 & co. more.
2802 Added Espec-1 format.
2804 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2805 of the protocol and it cannot be selected when encoding (maps into 'string'
2806 when decoding). Needed to talk to some servers.
2808 Demo client can request simple element set names.
2810 Added Diagnostic Format encoders/decoders.
2812 Added simple Close handling to frontend server (no hooks for resource
2813 reporting yet), and demonstration client.
2815 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2817 --- 1.0b3 1995/08/24
2819 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2820 handled incorrectly when records were requested in the searchResponse. This
2821 will only affect you if you use the frontend-server.
2823 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2824 Test-client will ask for and print GRS1. Ztest will return dummy records
2827 Added Explain encoders/decoders to the service-level API. Untested.
2829 Added Extended Services: Item Order encoders and decoders to the Service-
2830 level API. Untested. We could use a recent copy of the pertinent bits
2831 of the ILL protocol to add those bits.
2833 Added diagnostic format 1 encoders/decoders to the service-level API.
2836 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2837 odr_cons.c, which causes a more correct output.
2839 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2840 was always set to 0 when no records were requested in the searchRequest.
2842 * Added better external-handling. This shouldn't harm old code that
2843 *encodes* externals. It can break code that looks for a
2844 'single-ASN1-type' representation, since those types that are known
2845 are now decoded immediately. Look at the SUTRS sample code in
2846 seshigh.c and client.c. Documentation updated.
2848 Handling of structured records in bend_fetchresponse. Length -1 marks
2849 structured record, type is deduced from format field.
2851 --- 1.0b2 1995/06/27
2852 Fairly quick maintenance release to add SUTRS support.
2854 Fixed handling of SUTRS records in the demonstration client.
2856 * Added format field to the bend_fetchrequest and bend_fetchresponce
2857 structures of the backend API (frontend server). When the record is
2858 returned, the value of the format field is mapped to an OID. The
2859 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2860 of the record. The special value VAL_NONE in the bend_request means
2861 that no specific format was requested by the client. Documentation
2862 updated accordingly. Test server (ztest) will return a fixed dummy
2863 SUTRS record if your client requests SUTRS.
2865 Documentation updated accordingly.
2867 You can now set external libraries and RANLIB support in the top-level
2871 First public release.
