3 Fix yaz-config output: echo_source not set correctly by configure.
7 SOLR WebService support for yaz-client and ZOOM.
9 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
13 Z39.50 facet support. Facet specifications are passed for search in
14 other-information with ASN.1 as defined in facet.asn and OID
15 .10.1000.81.5 . Facets are expressed as an Attribute list as known
16 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
17 3 is limit (number of entries to get in response). yaz-ztest returns
18 dummy facets if a client asks for them.
22 CCL fixes: bug 2895 and bug 3539.
24 GR1-display: add comma in display - was removed by mistake in
27 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
29 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
33 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
34 result set from a connection. The result set will be on its own
35 thereafter; no operations on it will perform retrievals from a target.
36 Only cached copies are returned.
38 ZOOM C:fix case for HTTP servers responding with Connection:close.
39 Ensure that if there is a current task it is resumed (like fetching
40 more records in a result set) . Bug #3484.
42 PQF parser: use odr_atoi for Odr_int (not atoi)
44 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
45 values that contain any non-digits are treated as string attributes
46 (previously decoding only checked for leading character ([0-9]). PQF
47 encoding: attribute string values are not surrounded by double-quotes.
51 New utility for managing threads - thread_create.h.
53 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
54 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
55 but YAZ' implementation do.
57 Fixes for yaz_cond-functions on Windows 7.
59 DLL export more symbols.
61 zoomsh: show record do NOT render opac.
63 Remove *.la files from Debian and RPM packages.
67 Debian package libyaz-dev depends on libgnutls-dev again (was
68 removed in YAZ 4.0.6, but due to Libtool it is still needed
69 even though yaz-config do not list libgnutls libs).
71 ZOOM: Use only one WRBUF for returning string results for
72 ZOOM_resultset. Reduces memory usage for ZOOM in general.
74 ZOOM: ZOOM_connection do not use a shared pointer to
75 ZOOM_resultset after ZOOM_resultset is destructed by
76 user. Reverts to YAZ 4.0.4 behavior.
80 record-conv: fix problem with at least one XSL conversion -
81 due to probably incorrect usage of XML XSL documents.
85 Fix yaz-config for static mode and the use of SSL (gnutls).
89 Forward decl timeval struct in mutex.h and gettimeofday.h.
91 yaz-config: fix 'static' mode linking.
95 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
96 are wrappers for pthreads or Windows. For Windows these are put in
97 a separate DLL: yaz_cond4.
99 libyaz.la (whole source) is compiled with thread. If thread support
100 is enabled enabled, all source of YAZ is compiled with treading support.
101 This allows core utilities such as yaz_log to use thread facilities.
102 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
103 thread utilities. This commit moves mutex utilities (mutex.c) from
104 libyaz_server.la to libyaz.la.
106 yaz-json-parse displays leading text until error.
110 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
111 patch from Giannis Kosmas.
113 SRU: no longer URL encode SRU database. The URL for an SRU server is
114 a URL and such is alreeady encoded - at least when given with leading
115 http:// or https://. This reverts behavior to YAZ 3.0.50.
117 Support for new MARC XML notation TurboMARC which like MARCXML is a
118 complete representation of MARC/ISO2709.. This one, however, is more
119 compact and allows for faster processing with XSLT. TurboMARC can be
120 used in the marcdisp.h API, from the yaz-marcdump utility and from
123 yaz-ztest can be configured - via the database - to perform certain
124 delays when it performs operations search, present and single record
125 fetch. This allows testers to make yaz-ztest act as a real or even slow
126 Z39.50 server. Refer to the yaz-ztest man pages for details.
130 wrbuf_destroy allows NULL WRBUF passed to it.
132 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
134 Add ZOOM_connection_close.
136 No fixed size buffers for ZOOM shell - bug #3257.
138 tstodr: make it work on s390 platform.
140 New icu iterator-functions. The new icu_iter-functions makes it possible
141 to use ICU chains from many threads.
143 yaz-client: better syntax check for show command.
147 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
150 New simple local-file XML include facility which allows file glob-patterns.
151 Refer to yaz/xml_include.h.
153 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
156 ZOOM_record_get supports new parameter "format" which makes it format XML
159 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
160 JSONText in ECMA-262) is JSONValue, not JSONObject.
164 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
165 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
167 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
168 POSIX/Unix builds .so with major version 4.
170 Remove old LOG_-defines from log.h. They have been obsolete and
171 undefined by default for the last 5 years.
173 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
175 GFS: Remove socket (int *fd) from search_rr handler. The socket
176 descriptor ptr is a facility that allowed a search handler to supply
177 a socket which would serve as a callback - when search was complete.
178 This facility has now been in use for years.
180 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
181 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
182 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
183 returns 'const char *' rather than 'char *. The returned string is
184 read-only and should not be modified by applications. COMSTACK cs_close is
185 now a void function - it no longer returns int. No applications check for
186 the value and the implementations has always returned 0.
188 ZOOM: use size_t for scan hit counts and str size. Functions
189 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
190 occ (hit count) and len (string length) are now of type size_t pointer
191 rather than int pointer. This is to be able to represent large hit counts
192 and to also just to use the proper type for string length (strlen result).
194 New JSON parser. Refer to include/yaz/json.h .
196 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
197 Used to be int in some cases. Many wrbuf_-functions used to return an int
198 indicating some length.. These return values were never used. And so they
201 ODR: odr_malloc, odr_total now takes size_t for size.
203 clone_z_type: fix leak; occurred for encoding failures.
205 --- 3.0.52 2009/12/03
207 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
208 bug was introduced in 3.0.51.
210 --- 3.0.51 2009/12/02
212 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
214 tcpip comstack: fix leak for getaddrinfo.
216 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
217 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
218 Decoding of SRU "path" database is performed by private function
219 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
220 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
222 yaz-client: honor base command for SRU. Change when database setting
223 is applied for SRU and ensure it is kept when a connection is reset.
224 Change also the way errors are displayed or SRU (decoding of packages).
226 --- 3.0.50 2009/11/02
228 Add support for extra request / response data for SRU codecs and GFS.
229 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
230 for extra data response buffer and length. For the GFS, both request
231 and response data (XML) is carried in extra_args and extra_response_data
232 for the search handler. Patch by Ko van der Sloot.
234 ZOOM: For queries that cannot be converted to the specified rpnCharset,
235 ZOOM now returns a diagnostic on the client-side ('invalid query' /
236 10010). This fixes bug #2113.
238 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
239 cmdfile included a 'quit' command that would result in a memory violation.
241 --- 3.0.49 2009/10/01
243 Make a number of functions defined in xmlquery.c static. These have
244 never been declared in a public header file (yaz/xmlquery.h) and was
245 made public by mistake.
247 Improve speed of character conversions (iconv utilities). This makes
248 conversions from MARC-8 faster.
250 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
251 unless type desired is "raw". This will prevent type "xml" from
252 returning ISO2709 .. Which obviously can not be XML parsed.
254 Fix memory leak in ZOOM that would occur if option apdulog was used
255 on a re-used connection.
257 Frontend server logs HTTP requests.
259 Frontend server now sends Z39.50 close when it times out (sesssion has
260 been idle for too long). Versions 2.0.30 and earlier also sent close.
261 But due to a mistake this was disabled in all versions after that, i.e.
262 the server would just close the socket immediately.
264 yaz-client emits a better message when receiving an unrecognised
265 userInformationField.
267 Skip zero-length subfields when decoding ISO2709. This rare case happens
268 if a record has two FS characters in a sequence. Without this patch
269 there would be a reference beyond char array in using_code_len fragments
272 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
274 --- 3.0.48 2009/08/28
276 The show command offered by the zoomsh command now takes a 3d optional
277 parameter type which is what is passed to ZOOM_record. If the type
278 argument is omitted, "render" is used.
280 RPN to CQL conv may use USE string attributes (bug #2978).
282 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
284 --- 3.0.47 2009/07/08
286 Function yaz_xml2query allows a diagnostic element in the PQF XML
287 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
288 code and additional info respectively.
290 The BER BOOLEAN is now the integral type Odr_bool which still happens
291 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
292 typedef'd to Odr_int. This is still an integral 'int', but it may be
293 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
294 ASN-1 compiler as well as programs has been updated to use the new types.
296 --- 3.0.46 2009/06/08
298 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
299 only the bibliographic record was rendered. For type=opac, an OPAC
300 record is only returned if it is present.
302 iconv: small fix for encoding of advancegreek.
304 yaz-client: avoid double display of SRU/SRW records (bug #2798).
306 yaz-client: option auto_reconnect=on really reconnects.
308 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
310 server: avoid null ptr ref for for yaz_poll errors.
312 build: fix RPM build for RHEL 5.3.
314 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
316 --- 3.0.45 2009/03/31
318 Fixed bug #2709: TCP connect returns Invalid argument.
320 Fixed compilation for mingw.
322 Honor charset for raw records (ZOOM_record_get).
324 Fixed use of errno for threaded mode that was seen on Solaris 10.
326 Fixed argument passing with blanks in value for Windows Service.
328 Disable YAZ' own log rotate by default (no 1 GB limit).
329 The variable l_max_size which specifies the log file limit is set to 0
330 (DISABLED): This is due to the fact that YAZ is most often deployed using
331 logrotate. Also YAZ can not perform log rotate because of unsufficient
332 permissions (setuid).
334 --- 3.0.44 2009/02/17
336 List supported encodings in man page for yaz-iconv.
338 Fixed missing SSL libs for --libs output
340 Re-established OID record syntax application-xml. Nobody should use it
341 but we don't want to change soname because of this symbol being absent.
343 --- 3.0.42 2009/02/02
345 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
347 Added member named_result_sets for init handler struct for the GFS. This
348 allows a server to disable named result sets.
350 Removed OID record syntax application-xml.
352 Added support for rule-based transliterator for ICU wrapper of YAZ.
354 Fixed bug #1902: yaz-icu XML output.
356 Make YAZ checks Emacs friendly.
358 BITSTRING value shows value. Bug #2346.
360 ISO2709 decoding: skip control characters from indicator data.
362 Omit sort key by default in yaz-icu's output.
364 Allow combined single char options (again) for YAZ' options function.
366 Utility yaz-marcdump got option to display YAZ version (-V).
368 Allow YAZ to use ICU 3.4.
370 Added new ICU test case which illustrates removal of diacritics.
372 --- 3.0.41 2008/12/29
374 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
376 --- 3.0.40 2008/12/29
378 For configure, using option --without-xml2 also disables Libxslt/Libexslt
381 Fixed bug #2352: yaz-marcdump crashes for certain record.
383 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
385 Added support for Danmarc2 to UTF-8 conversion.
387 Added support for ISO5426 to UTF-8 conversion.
389 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
390 implementation version.
392 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
394 --- 3.0.38 2008/11/10
396 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
397 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
399 ZOOM C now interprets databaseName option for ZOOM connection as path
402 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
404 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
406 Dummy Libxml2 types no longer defined in headers of YAZ'.
408 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
411 --- 3.0.36 2008/09/26
413 Various ODR chapter fixes.
415 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
417 Added missing source for Windows compilation, mutex.c.
419 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
421 For SRU connections in ZOOM all records up to "count" are now fetched.
423 Fixed crash in generic frontend server (and yaz-ztest) which occurred
424 in Windows due to bad error handling for Libxml2.
426 Added facility for sending arbitrary records (ASN.1 any) using
427 ZOOM C's Extended service update. Patch by Sam Reynolds.
429 New options for ZOOM C's connection, logapdu which makes ZOOM log
432 --- 3.0.34 2008/06/18
434 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
436 --- 3.0.32 2008/06/12
438 Fixed memory violation that could occur when decoding UTF-8. This bug
439 was only present in 3.0.30 of YAZ.
441 --- 3.0.30 2008/06/06
443 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
444 GNU TLS is used by default (if found).
446 yaz-ztest returns OPAC records if a client asks for OPAC.
448 Improved speed of MARC-8 encoding.
450 Added support for lossy and loss-less MARC-8 encoding.
452 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
454 Added new Windows Service wrapper (sc).
456 yaz-client's itemorder command may now send a file.
458 Fixed yaz-marcdump to allow the use of NS prefix for record element.
460 Added new function yaz_log_xml_errors.
462 Allow (but warn) unknown XML attributes in MARCXML parsing.
464 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
466 The UTF-8 to MARC-8 conversion now uses a different set of characters
467 for Greek symbols. Bug #2120.
469 --- 3.0.26 2008/02/21
471 Added yaz_daemon (daemon.h).
473 Fixed bug #2068: pkg-config trouble
475 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
477 --- 3.0.24 2008/01/28
479 Document --with-xml2 option.
481 Added OPAC XML XSD (etc/opacxml.xsd).
483 Allow glob mask for name attribute in retrieval element for the
484 generic frontend server's retrieval facility.
486 Changed yaz_poll_poll to return yaz_poll_except for all returned events
487 except POLLIN/POLLOUT.
489 Fixed error handling in cs_listen. Bug #2037.
491 --- 3.0.22 2008/01/20
493 Fixed version in yaz/yaz-version.h.
495 Fixed bug #2027: Crash when closing connection.
497 Changed configure so that ICU support is only enabled if only ICU
498 and Libxml2 is available (because the ICU chain is XML based).
500 --- 3.0.20 2008/01/15
502 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
503 is built. Only this DLL depends on the ICU runtime.
505 yaz-ziffy is no longer part of YAZ. It is distributed separately by
506 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
508 Changed license of CCL module to 'Revised BSD'. After consultation with
509 remaining members of the original EUROPAGATE consortium, we are re-issuing
510 the CCL module without a separate license. The software was developed by
511 Index Data as part of a research project. The special license was included
512 to help feed usage information back to the project consortium to support
513 project evaluation. At this time, the project consortium has long-since
514 disbanded, and the majority of the original principals have retired. At the
515 same time, we have significantly modified the software during the following
516 years, to the point where very practically no original code remains. To
517 simplify re-use of the software, we have contacted those members of the
518 consortium who could be reached, and agreed to re-issue the module as a
519 proper part of the YAZ package.
521 Tcl scripts uses /usr/bin/tclsh as preferred shell.
523 CQL closer to being version 1.2 compliant. CQL also allows free-form
524 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
527 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
528 bug could make Extended services handling crash in the ZOOM layer. This
529 bug was only present in YAZ 3.0.18.
531 --- 3.0.18 2007/12/19
533 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
536 yaz-marcdump reads and writes collection wrapped records.
538 Handle OPAC for record conversion module.
540 Fixes for ICU wrapper.
542 Allow ICU libs to be controlled with --with-icu .
544 --- 3.0.16 2007/11/12
546 Added yaz_poll which is a wrapper for select/poll. When poll is available
547 and non-buggy, it is used, by yaz_poll . This allows more than 1024
548 sockets to be in use.
550 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
551 functionality through an XML based configuration (ICU chain). This system
552 is useful for search facilities such as Pazpar2 and Zebra that needs to
553 perform tokenization of indexed material. The ICU code in a separate
554 library libyaz3_icu.a.
556 Added HTTP tunnel facility for COMSTACK, bug #1752.
557 This is a facility that allows a Web proxy, such as squid, to tunnel
558 Z39.50 traffic. This facility is "transparent" to must applications
559 using YAZ. It's enabled by using pseudo transport connect: followed by
560 the proxy address, followed by command, then follwed by he regular
561 "virtual" addresss. For example,
562 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
564 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
566 --- 3.0.14 2007/09/21
568 Fixed bad memory reference in ZOOM_record - cuased by member not being
569 initialized. This was a problem only in YAZ 3.0.12.
571 Fixed bug in conversion from MARC to XML: Non-XML characters in control
572 fields were not removed.
574 Changed the way C code is generated from codetables.xml. Made a MARC-8
575 conversion trie for each characterSet section rather than codeTable.
576 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
577 of codetables.xml from Larry Dixson, LOC. Bug #1464.
579 --- 3.0.12 2007/09/12
581 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
582 from ZOOM_record_error).
584 ZOOM C function ZOOM_record_get returns record schema for type="schema".
586 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
588 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
590 Better SRW-to-Bib-1 diagnostic mapping.
592 ZOOM C and yaz-client announces SRU version 1.2 by default.
594 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
597 Fixed in yaz_sru_decode to allow other version than 1.1.
599 --- 3.0.10 2007/08/22
601 Added support for SRU scan for ZOOM.
603 Added support for the use of the older versions or Extended Service
604 Update in ZOOM. To faciliate this, an option "updateVersion" may be
605 set to the version , 1=first, 2=second, 3=third. The third version is
606 what ZOOM C has used so far. And that, obviously, is the default.
608 Added support for CCL queries in Z39.50 queries sent to the GFS (and
609 therefore in Zebra and in SimpleServer-based applications). The new
610 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
611 qualifier file used to transform incoming CCL queries into Type-1 RPN,
612 which is passed into the back-end search callback function.
614 Added support for HTTP Basic authentication in clients: the SRU/W
615 codec encodes the username/password elements of the PDU structure
616 appropriately, and these may be set using the "user" and "password"
617 options in ZOOM-C applications (the same options that are used for
618 Z39.50 authentication).
622 Fixed bug #1208: SSL appears to be broken in ZOOM.
624 Fixed bug #1206: Libxml2 include path weirdness.
626 Added oid_name_to_dotstring.
628 Allow elementSetName to be specified for ZOOM C record update.
630 Allow waitAction to be specified for ZOOM C based for Extended Services.
632 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
633 syntax OID. Bug introduced in YAZ 3 series.
635 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
639 Fixed bug #1157: yaz-client does not read .yazclientrc from current
640 directory. yaz-client now reads commands from file given by option -f
641 if specified; then tries to read .yazclientrc in current directory.
642 Failing that, it reads .yazclientrc from user's home directory.
644 Added support for correlationInfo Note and ID for Record Update via
647 Added yaz-client command querycharset which specifies character set for
648 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
649 (termListAndStartPoint).
651 Charset ISO5428:1984 is an alias for ISO5428-1984.
653 Implemented a way to perform scan in a result set using Z39.50. This
654 is achieved by attaching the result set name in the characterInfo
655 (type InternationalString) of OtherInformation in the Scan Request PDU.
656 The result set is identified in the otherinformation by the new OID:
657 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
658 This allows for scan in result set and faceted search . Zebra did some
659 of this in the APT term using attribute type 8 and value being result
660 set. Using the OtherInformation approach for this is cleaner and easier
661 to work with in proxies and the like. This facility can be used in
662 yaz-client using new command setscan which takes a result set as first
663 argument, start position (APT) as second.
665 Changed decoding of SRU XML packed records to deal with servers that
666 have recordData with XML data with multiple root nodes. Also make
667 comparison for recordPacking case insensitive. Again, one server
668 returns "XML" where others return "xml".
670 For SRU responses allow Content-Type application/xml as well as text/xml.
674 Fixed bug in character set conversion of BER strings. Bug introduced
679 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
681 For OID class, use oid_class consistently.
683 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
686 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
687 character set for bibliographic information interchange". By Giannis Kosmas.
689 Added documentation on new OID API.
693 Changes to generic frontend server interface: added new member
694 'query_charset' for bend_initrequest structure. A backend init handler
695 should set this member to its native character set for query terms.
696 When defined, the frontend server logic will announce this character set
697 to a client if the negotiationModel bit is set by the client. All server
698 implementors are encouraged to specify this. If a backend server does not
699 specify this a warning is issued using yaz_log(YLOG_WARN,..).
701 Added CCL utility to remove terms (stop words) from resulting RPN
702 tree. This is handled by functions with prefix ccl_stop_words_ .
704 New ZOOM C option, "rpnCharset", which allows client-side conversion of
705 terms in RPN queries.
707 Clean-up the CCL API. Moved some internal structures from ccl.h to
708 private header cclp.h. Changed ccl_parser_create so that a Bibset must
709 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
710 This is replaced by ccl_parser_find_str which takes a string instead.
712 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
713 libyaz.la is the core of YAZ except the generic frontend server and
714 does not depend on POSIX threads anymore. libyaz_server.la is the
715 generic frontend server facilities and uses POSIX thread functionality
716 if available. The libyaz.la no longer depends on POSIX threads because
717 the number of global structures is limited. NMEM no longer re-uses blocks
718 between threads ; it simply free's memory immediately but allocates in
719 "large" chunks as usual. We don't expect any performance penalties
720 because of this. The yaz_log system is still using a global log_level so
721 caution must be taken when modifying it with yaz_log_init_.. +
722 yaz_log_mask_str. This, however, should not cause any trouble because
723 these functions are called during initialization of application code
724 anyway. `yaz-config --libs server` returns libs for server applications;
725 `yaz-config --libs` returns libs for non-server applications.
727 New OID database - with public definitions in oid_db.h. Removed old OID
728 database including the head oid.h and definitions such as enum oid_value
729 and struct oident. The new OID database uses the same string names as
730 before but the 'protocol' is gone. There are now only two representations
731 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
732 converts from string to OID; functions with prefix yaz_oid_to_string
733 converts the other way.
735 Change to emit_term() in CQL-to-PQF query translation: when a term has
736 the /regexp relation modifier, do not process it for leading and
737 trailing "^" and "*", which have quite different meanings in regular
740 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
741 write handlers no longer carries a 'last' parameter. This will make
742 yaz_iconv flush "less" characters. A flush is performed by call to
743 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
745 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
746 removed, because function yaz_query_to_wrbuf does the same.
748 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
749 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
751 Deprecated MARC utility functions removed.
753 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
756 Branch split: YAZ_2_1_55_branch
758 --- 2.1.54 2007/03/16
760 Fix to ZOOM-C so that transparent reconnection is properly handled on
761 connections that are in asynchronous mode.
763 Fixed compilation on OpenBSD 4.0.
765 Large strings in GRS-1 records are now properly displayed in yaz-client.
767 Added character conversion support for "advancegreek"; based on patch from
770 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
771 sequence is met. Before the error was not set so it would be unknown.
773 Adjust yaz-marcdump MARC reader so that it skips until record separator
776 --- 2.1.52 2007/03/07
778 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
779 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
780 fd_set structure used as a bitmask for the FDs to be selected on.
782 Using ACX_PTHREAD macro to check for POSIX threads.
784 Fixed have-vsnprintf check.
786 --- 2.1.50 2007/02/23
788 Fixes for configure on BSD. Bug #900.
790 Added snprintf/vsnprintf wrappers for systems that don't have
791 limits (heavens forbid).
793 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
794 created before all previous tasks were completed and removed from the
795 task queue, the new task could be removed by a mistake.
797 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
799 Implemented pass-through CQL-to-PQF conversions. Bug #861.
801 Fixed bug #832: Problem with MARC/charset in yaz-client.
803 Fixed bug #668: save command line history for yaz-client.
805 Fixed bug #830: pkg-config support.
807 --- 2.1.48 2007/01/23
809 Extended ZOOM result set options with two options that may be read by
810 a client: resultSetStatus and presentStatus with values as specified for
812 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
814 Fixed bug #827: Using SSL fails on Debian etch.
816 Fixed bug #826: Weird looking chars for set of MARC records.
818 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
819 that is treated as an ItemOrder with itemRequest being an XML document
820 external. The value of "doc" is the content.
822 Extended the GFS search facility. New member of bend_search_rr
823 'estimated_hit_count' signals that hits is known to be an estmate
824 (higher or lower than real hit count). New member 'partial_resultset'
825 signals that the search was partial (hit count is lower or equal than
826 real hit count). For Z39.50, the information is stored in resultSetStatus
827 member of SearchResponse APDU. For SRU, the information is signalled
828 via SRU diagnostic 59: "Result set created with valid partial results
831 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
833 --- 2.1.46 2007/01/13
835 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
837 Added ZOOM_connection_peek_event.
839 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
840 the following new functions:
841 ZOOM_event_nonblock, ZOOM_connection_process,
842 ZOOM_connection_get_{socket,mask,timeout},
843 ZOOM_connection_fire_event_{timeout,socket}.
844 The existing blocking event handler, ZOOM_event, is a wrapper for the
845 + blocking ZOOM_event_sys_{poll,select}.
847 Implemented function ccl_xml_config which parses XML version of CCL
848 configuration (bug #798).
850 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
852 Added timings utility (yaz/timing.h)
854 --- 2.1.44 2007/01/03
856 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
859 Fixed bug #779: Rotation of apdu.log fails.
861 Fixed for character set conversions:
862 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
863 Honor G1 set in MARC-8 decoding.
865 --- 2.1.42 2006/12/17
867 Fixed bug #775: char conversion does not handle Alternative UTF-8
870 Implemented function yaz_marc_read_line which parses MARC line format
871 records. There is a wealth of formats out there. So far, this function
872 reads line records produced by yaz_marc_write_line.
874 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
875 more generic and easier to remember(!) options: -i format and -o format
876 which specifies input format and output format respectively - where
877 format is one of "marc", "marcxml", "line", "marcxchange".
879 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
880 does not print anything except warnings for records.
882 For yaz-marcdump, added support for MARC split into files (-s) with a given
885 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
886 spec, at http://www.loc.gov/standards/sru/record-update/
887 This has changed the binary layout of the following structs:
888 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
889 bend_update_rr . Patch by Ko van der Sloot.
891 Added GFS utility function bend_assoc_is_alive which returns 1 if
892 association is still alive (client is connected); 0 otherwise (client
893 closed connection). This allows busy servers to stop working for
896 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
897 been a separate piece of software. This version of ziffy has been modified
898 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
900 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
902 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
903 Client code may now interrogate options such as "init_opt_sort" to
904 find out whether the server claims to support various options.
906 --- 2.1.40 2006/11/27
908 Added utilities yaz_{set,get}_esn to set/get element set name from
911 Removed the build of libyazthread.la. The libyaz.so is the threaded version
912 of YAZ and has been so since YAZ 2.1.10.
914 Implemented ZOOM_record_error which returns error information for
915 record (surrogate diagnostic).
917 --- 2.1.38 2006/10/31
919 Updates for SRU Update by Ko van der Sloot:
920 1. Changed name from "operation" to "action"
921 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
922 versions in the code, marked as 'backward compatible'.
923 3. Added diagnostics for SRU Update.
925 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
927 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
929 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
931 For GFS, fixed problem with SRU diagnostic 'First record position out of
932 range' being issued for 0 hits.
934 zoomtst10 part of Windows Build.
936 --- 2.1.36 2006/10/13
938 Implemented yaz_filepath_comp which splits a path into file path
939 components (required by Zebra 2.0.3+).
941 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
942 BSD inspired license until now so this should not have any real impact on
943 anybody. See http://www.opensource.org/licenses/bsd-license.php
945 Fixed bug #687: Missing log lines.
947 Fixed bug #678: CQL to PQF translation does not preserve double-quote
950 Fixed bug #689: SRU diagnostics to be added.
952 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
953 whether a connection is idle (no more work do do).
955 --- 2.1.34 2006/10/04
957 Change type of optval from long to int for invocation of setsockopt with
958 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
960 Added support for specifying the max log file size for the Generic
961 Frontend Server. The size is given with option -r.
963 --- 2.1.32 2006/09/21
965 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
967 --- 2.1.30 2006/09/17
969 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
972 Fixed bug in Generic Frontend Server that could cause a server to stop
973 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
975 For the generic frontend server, the maximum record size is used as maximum
976 size of incoming packages (SRU + Z39.50). The value until was previously
977 only used in Z39.50 Init negotiation and, later, in a session controlled
978 sizes of records returned. This is controlled using -k option. It can be
979 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
981 --- 2.1.28 2006/09/04
983 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
986 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
988 New option for yaz-marcdump -lpos=value which allows setting a portion
989 of MARC header to a certain value.
991 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
993 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
994 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
996 --- 2.1.26 2006/08/15
998 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1001 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1003 --- 2.1.24 2006/08/08
1005 Fixed MARC ISO2709 encoding routines to deal with character set
1008 Minor changes to GFS logging. Database included in search request log
1011 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1012 cached/multiple records.
1014 Shared libraries are built by default on Unix+configure.
1016 Changed cql2pqf transformation to use a different evaluation order. The
1017 new order is: always, relation, structure, position, truncation, index
1018 and relationModifier. Old order was: always, relation, relationModifier,
1019 structure, index, position, truncation. Note that the the latter ones
1020 override former ones for identical attributes.. The new scheme means that
1021 it is possible to override any existing attribute with a relationModifier.
1022 And also that it is possible to override everything for the index rule
1023 (except the ones listed in relationModifier). No order is perfect but this
1024 one, we believe, covers more real cases.. The "always" should have been
1025 called "default", since the attributes there can be overridden with all
1028 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1029 compilation phase, but also for yaz-config --cflags output. This allows
1030 us to have public headers with Libxml2 stuff in them . It should also,
1031 eventually, make Libxml2 checks redundant in packages using YAZ, such
1034 --- 2.1.22 2006/06/15
1036 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1037 stored in uri, message and details.. Previously diagnostics were stored
1038 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1039 compatibility.. but he's probably the only one affected, so.
1041 Added support for CCL, compiled on the client side, in ZOOM-C. This
1042 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1043 input; the resulting query objects can be used for for searching with
1044 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1046 YAZ' configure searches for OpenSSL by default.
1048 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1049 SL_CTX_use_certificate_file. See
1050 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1051 for more info. Thanks to Ko van der Sloot.
1053 --- 2.1.20 2006/06/02
1055 Bug #600: SRU GET, POST support for yaz-client. Introduced
1056 command 'sru' which selects method SOAP/GET/POST.
1058 Allow missingValueAction to be specified for the sortspec string -
1059 function yaz_sort_spec. By default, the missing value action is null.
1060 Use ! to specify "abort". Use = followed by stringvalue to specify default
1063 Ensured that Present-handler (if defined) is called in GFS before any call to
1064 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1065 searchRetrieve requests.
1067 Documentation for YAZ is now based on the Docbook XML/XSLT using
1068 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1069 is no longer depending on jade/openjade or docbook-to-man scripts.
1070 PDF is no longer part of the distribution - but can optionally be
1071 made using DSSSL/jadetex or FOP.
1073 Added retrieval handling support in Generic Frontend Server to support
1074 conversion between MARC/XML as well as XSLTtransforms. See
1075 etc/yazgfs.xml for an example.
1077 Added Authentication support to Generic Frontend Server in SRU
1078 mode. Authentication using HTTP Basic is supported, as is the use
1079 of 'x-username' and 'x-password' parameters in the request itself.
1081 Added support for a new character set MARC8s identical to MARC8 except
1082 that it converts combined characters to single Unicode characters in the
1083 Latin-1 range (when possible).
1085 --- 2.1.18 2006/04/24
1087 ASN.1 compiler 0.4: generates brief Doxygen file header for
1088 generated .h/.c files.
1090 Utility yaz_iconv now supports conversion to MARC-8.
1092 New facilities for the MARC module. The reading - and writing of
1093 content are separate methods for the yaz_marc_t handle. The following
1094 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1095 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1096 format). Write functions have prefix yaz_marc_write_.. The existing
1097 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1098 available. Removed support for OAI-MARC and simplexml (not the
1099 simplexml from PHP5).
1101 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1102 to be returned for this connection.
1104 --- 2.1.16 2006/03/31
1106 Allow multiple languages and charsets to be specified with
1107 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1108 negcharset iso-8859-1,utf-8
1110 Translation of proximity nodes from CQL into PQF now works.
1112 Moved to automake 1.8, 1.9.
1114 Added function yaz_log_set_handler which allows a log handler to be
1115 installed. This handler will be called for all log messages. Output
1116 to file is also produced; but that can be disabled by passing NULL
1117 fname to yaz_log_init_file.
1119 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1121 For SRW (including GFS), accept application/soap+xml as content-type
1124 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1125 produces NO stylesheet reference even if a default stylesheet is specified
1128 --- 2.1.14 2006/03/14
1130 Updated Windows package to include yazd.dll + yazd.lib for the
1131 Development component.
1133 If the environment variable YAZ_LOG is set, then it is used as a
1134 string indicating the default level of logging to use if not
1135 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1136 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1137 used as before. So, for example, to omit warnings from YAZ logging,
1138 export YAZ_LOG=-warn
1140 cql_transform() now map structure and other attributes before indexes,
1141 so that index-specific structures and other attributes can override
1142 defaults. So now a combination of mapping specifications such as:
1144 index.dc.date = 1=date-modified 4=5
1145 does the right thing.
1147 cql_transform() now also respects the "always" mapping specification,
1148 which establishes an initial set of attributes to be used for all
1149 terms except where overridden by more specific attributes associated
1150 with the index, relation or modifier.
1152 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1153 which mode to use; one of "post", "get" or "soap" (SRW, default).
1155 Fixes for yaz_iconv routines: changed trie-based character set conversions
1156 to use only non-negative values for bit fields due to Sun's C compiler not
1157 supporting negative values.
1159 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1160 sequences where not read correctly. Fix by Rustam Usmanov.
1162 Updated win/makefile to use options, settings which makes things
1163 compile with VS C 2005.
1165 --- 2.1.12 2006/02/01
1167 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1169 In ZOOM socket code, use select instead of poll on MacOSX.
1171 ZOOM-C now support client-side compilation of CQL into RPN that is
1172 sent to the server, enabling CQL to be used against all Z39.50
1173 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1174 ZOOM_query object, and submit it using ZOOM_connection_search().
1175 The CQL-to-RPN translation uses a configuration file, the name of
1176 which must be specified in the Connection's "cqlfile" option.
1178 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1179 function, which takes as its start-term parameter a ZOOM_query object
1180 (which may have had either CQL or RPN set into it).
1183 --- 2.1.10 2005/11/29
1185 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1186 GFS to support this as well. Backend handler, bend_srw_update, does the
1187 update work. Code contributed by Ko van der Sloot.
1189 Allow retrieval of Search Result-1 information in ZOOM by the use of
1190 options that are attached to a result set. ZOOM documentation updated
1193 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1194 UTF-8 conversion. Patch by Raj Patel.
1196 Added option -m to GFS to control formatting of timestamps in log file.
1198 Added 'exit' as synonym for 'quit' in yaz-client
1200 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1201 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1202 for the new members. Patch by Ko van der Sloot.
1204 Added support for SRU POST. It is supported for content-type
1205 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1207 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1208 Instead make the library libyaz.la multi-threaded. Threading as a whole
1209 can still be disabled by configure option --disable-threads. Previosly,
1210 with older GLIBCs there were problems with MT libs under Apache. This
1211 has now been fixed a long time ago.
1213 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1216 CQL module modified to be case insensitive for relations/indexes/operations.
1218 Fixed bug in CQL transform code: incorrect value relationModifieder
1221 Added 'show all' command for yaz-client which retrieves all results
1224 Added new yaz-client, xmles, which takes a (private) OID and
1225 a document to be sent as an extended service request.
1227 Describe new yaz-client commands wait_response and set_auto_wait.
1229 Increase TCP/IP listener backlog from 3 (which I am guessing was
1230 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1231 that the socket will queue as many incoming connections as it's able
1232 to handle ongoing connections. In other words, it will never now
1233 refuse a connection that it would be able to handle merely because
1234 it's not got around to accepting() enough of the pending connections
1235 yet. This is the behaviour anyway under Linux, where the listen()
1236 argument is ignored; but not under BSD and on systems such as
1237 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1238 YAZ-based servers should now be uniform across operating systems in
1241 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1242 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1243 This allows yaz-marcdump to read large MARC batches (>2 GB).
1245 Modified all YAZ source files - except the source which is auto-generated
1246 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1249 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1250 corresponding to the existing *_setl() function. These allow option
1251 values containing arbitrary valuues.
1253 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1254 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1255 except that it returns an indicator of whether or not the sort
1256 criterion was accepted (0 for OK, -1 for invalid).
1258 --- 2.1.8 2005/06/07
1260 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1261 MARC output rather than returning "new" buffer.
1263 yaz-client warns about unknown init options.
1265 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1267 --- 2.1.6 2005/05/24
1269 Added support for SRW sort in Generic Frontend Server. Patch
1270 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1271 sortKeys - or NULL if none is provided.
1273 Fixed bug #307: It was impossible to specify indefinite/no timeout
1274 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1277 Added support for multiple languages and charsets to be specified in
1278 ZOOM. Each charset/language is separated by a blank. If negotiation is
1279 in effect in init-response, Option
1280 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1281 Code based on patch by Vasiliy Osadchuk.
1283 Fixed bug #306: infinite recursion that occurred when calling
1284 yaz_log_level_init as the first call (before other log level or
1287 Fixed bug in scan handling in front end server: if preferred-Position-In-
1288 Response was non-present, a NULL pointer referece was performed.
1290 --- 2.1.4 2005/04/26
1292 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1293 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1294 now defined for all those error codes. So instead of putting 109 in
1295 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1296 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1298 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1301 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1303 Program yaz-client now exits and produces an error message if multiple
1304 Z39.50 servers are specified on the command line (none or one allowed
1307 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1310 --- 2.1.2 2005/03/16
1312 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1314 Fixed bug #272: Preserve spacing for CCL terms.
1316 --- 2.1.0 2005/03/14
1318 Added support for virtual hosts and multiple backend servers for
1319 the YAZ frontend server. The configution is XML based and
1320 support specificition of CQL to RPN mappings and explain information.
1321 See section "Virtual Hosts" in the YAZ manual.
1323 Extended OPAC display utility. OPAC display utility renders
1324 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1325 to supplement yaz_marc_decode_wrbuf.
1327 Fixed a bug in MARC decoder that could caused it to crash for some
1328 invalid MARC records. More diagnostics and warnings where added in
1329 XML output (warnings, etc are stored in comments).
1331 --- 2.0.34 2005/02/08
1333 Fixes for UNIX domain sockets. Bug #261.
1335 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1337 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1338 Added yaz_marc_subfield_str which defines subfield lead string which is
1339 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1340 yaz_marc_endline_str which defines end of fields string used in
1341 YAZ_MARC_LINE format. Default string is newline.
1343 Experimental support for MarcXChange. This format can be produced
1344 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1345 http://www.bs.dk/standards/MarcXchange.xsd
1347 Added yaz-client commands scansize that sets maximum number of
1348 entries to be returned by scan.
1350 --- 2.0.32 2005/01/11
1352 Added support for SRW scan in yaz-client and Generic Frontend Server.
1354 * Added whereInList member to SRW Scan Term.
1356 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1358 Fixed NMEM system to return aligned blocks on the smallest boundaries
1359 that are suitably aligned for all possible types on the particular
1360 architecture YAZ is being built for.
1362 --- 2.0.30 2005/01/04
1364 Fixed numerious warnings that was issued with newer versions of GCC.
1366 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1367 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1370 Make YAZ Generic Frontend Server slightly faster.
1372 Enhance (and reduce) logging for Generic Frontend Server.
1374 Revert YAZ log system so that it flushes every write operation
1375 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1377 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1378 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1379 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1380 will effectively disable old definitions.
1382 --- 2.0.28 2004/11/09
1384 Added yaz_log_time_format which specifies log format using
1387 Added yaz_log_module_level which returns mask for a module. Value
1388 is non-zero mask a if module is enabled; zero if disabled.
1390 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1391 in include/yaz/cql.h.
1393 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1395 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1397 Fixed bug #172: RPM builds does not enable SSL.
1399 Doxyfile.in part of dist. Doxyfile generated by configure.
1401 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1402 are given and the corresponding component does not exist.
1404 Extend CCL documentation in YAZ reference. Describe r=r.
1406 --- 2.0.26 2004/10/01
1408 Fixed MARC->MARCXML conversion to properly deal with
1409 fields, subfields, indicators having non-ASCII characters.
1411 Fixed MARC->MARCXML conversion so that ASCII control characters
1412 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1415 Added YAZ GFS support for conversion from Z39.50 surrogate
1416 diagnostics to SRW surrogate diagnostics.
1418 Bug fix: YAZ GFS did not return schema in explainResponse.
1420 --- 2.0.25 2004/09/30
1422 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1423 now converts recordSchema to elementSetName as well as schema URI.
1425 Fixed bug in COMSTACK that prevented HTTP request packages from being
1428 --- 2.0.24 2004/09/29
1430 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1431 does not require white-space before and after the dash in a range, e.g.
1432 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1435 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1436 due to new GCC removing "redundant" code.
1438 Added yaz-client commands scanpos and scanstep that sets preferred
1439 position and step-size for scan.
1441 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1443 Added CCL utility ccl_qual_buf which parses one or more CCL
1444 spec lines in a buffer.
1446 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1447 of name and value - ignoring empty lines and comments.
1449 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1451 Added odr_get_element_path which returns current element path for an
1452 ODR handle. This utility is useful in error handling or user-defined
1455 Added ODR_PRINT utility odr_set_stream which is is a more generic
1456 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1457 to a write function and pointer to close function. The close function - if
1458 non-NULL - will be called during odr_destroy.
1460 Fixed bug in CCL parser where truncation char was not removed from
1461 right side when truncation=both was in effect.
1463 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1466 --- 2.0.23 2004/08/11
1468 Fix buffer overrun in CQL parser when dealing with proximity (%).
1470 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1471 to UTF-8/UCS conversion is now only based on codetables.xml.
1473 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1475 --- 2.0.22 2004/08/06
1477 Add support for more "commit changes" in ZOOM (uses Extended Services).
1479 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1482 Yet another small fix for configure of SSL.
1484 --- 2.0.21 2004/05/14
1486 Fix SSL libs for configure when --with-openssl=DIR is given.
1488 --- 2.0.20 2004/05/10
1490 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1492 SSL comstack now uses yaz.pem certificate file on server side
1493 by default. Certificate filename can be configured by calling
1494 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1496 Fix bug regarding multiple calls to ZOOM_connection_connect.
1498 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1500 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1501 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1503 ZOOM now allows inspection of X509 peer certificate for verification.
1504 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1506 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1507 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1508 as "modular" but it simplifies things.
1510 Added cs_get_peer_certificate to that returns peer X509 PEM.
1512 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1513 NULL if SSL is unavailable.
1515 Documentation about MARC decoding tools.
1517 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1519 --- 2.0.19 2004/03/30
1521 Rename CHANGELOG to NEWS to follow GNU style packing.
1523 Fix bug with missing initialization of member in init_diagnostics.
1524 This bug affects threaded version of GFS server.
1526 --- 2.0.18 2004/03/20
1528 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1531 Ensure zlib.dll is packed with Windows install.
1533 --- 2.0.17 2004/03/17
1535 Fix encoding of xsd:string to use text instead of CDATA.
1537 Fix endless loop in CQL parser with unbalanced ".
1539 Use a more compact way to store MARC-8 conversion tables.
1541 --- 2.0.16 2004/03/16 Debian only
1543 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1546 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1551 --- 2.0.15 2004/03/01
1553 Another fix for decoding of XML packed records.
1555 --- 2.0.14 2004/02/25
1557 Fixes for Chunked encoding. White space not ignored after length spec.
1559 Update NS and use default NS for SRW diagnostic elements.
1561 --- 2.0.13 2004/02/23
1563 Implement ZOOM_resultset_cache_reset which resets record cache.
1565 Implement ZOOM_resultset_sort which sorts a result set.
1567 Implement chunked HTTP transfer.
1569 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1571 --- 2.0.12 2004/02/16
1573 Added member 'schema' to bend_explain_rr structure so that backend
1574 can specify explain record identifier. Defaults to Zeerex 2.0.
1576 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1578 --- 2.0.11 2004/02/16
1580 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1583 Added init command for yaz-client which sends "extra" init request.
1585 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1586 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1588 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1590 Make ZOOM error code for "invalid query".
1592 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1594 --- 2.0.10 2004/02/05
1596 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1599 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1601 Added option -p <file> to make Generic Frontend Server to write PID file.
1603 Added option -D to put Generic Frontend Server in background on its own.
1605 Make ZOOM C recognize option "password". If unset, "pass" is used
1606 (for backwards compatibility).
1608 Fixed a bug in Generic Frontend Server that could make it crash if a
1609 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1612 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1613 Must be issued before open, in order to be in effect.
1615 --- 2.0.9-6 2004/01/12 Debian/Windows
1617 Make the SRU server more picky WRT unknown params, etc.
1619 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1621 New YAZ client command, options, that sets Z39.50 options.
1623 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1624 options from a string of tokens (one token for each option bit).
1626 Update SRW diagnostic code messages.
1628 --- 2.0.9-5 2004/01/07 Debian/Windows
1630 Handle user defined stylesheet for SRW/SRU.
1632 --- 2.0.9-4 2004/01/06 Debian/Windows
1634 Fix bug in decoding of Content-Length.
1636 --- 2.0.9-3 2004/01/06 Debian/Windows
1638 Fix a bug with decoding of XML packed records.
1640 --- 2.0.9-2 2004/01/05 Debian only
1642 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1644 Fix bug in SRW/SRU diagnostics decoding.
1646 --- 2.0.9 2004/01/05
1648 Fixed bug in Generic Frontend Server which could drop records exceeding
1649 preferred message size. Reported and fixed by Irina Dijour.
1651 Fixed calculation of package size for structured records in Generic
1652 Frontend Server. Reported and fixed by Irina Dijour.
1654 Fixed namespace for SRW/SRU diagnostics.
1656 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1658 --- 2.0.8 2003/12/22
1660 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1661 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1664 CQL changes to reflect recent changes to the specification:
1665 * Documentation talks about context sets instead of index sets.
1666 * Documentation talks about indexes instead of qualifiers.
1667 * The CQL-to-PQF transformer's configuration file now uses
1668 "index.set.name = <attributes>" instead of the old form
1669 "qualifier.set.name = <attributes>". (Both forms are still
1670 understood but the latter is deprecated.)
1671 * CQL terms with no explicit index specified are now interpreted as
1672 cql.serverChoice instead of srw.serverChoice (which of course
1673 behaves exactly the same.)
1675 --- 2.0.7 2003/12/16
1677 MARC conversion can now generate ISO2709 output in another
1678 character set. yaz-marcdump uses this facility if you invoke it
1681 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1682 functions from there can be used from C++.
1684 --- 2.0.6 2003/12/04
1686 Frontend server now transfers memory from decoded packages to stream
1689 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1690 references to show up.
1692 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1693 the ZOOM Abstract API. The older names for the same options are still
1694 also supported for the benefit of old applications.
1696 ZOOM-C supports "implementationId" and "implementationVersion" options
1697 to go along with "implementationName". These allow the user code to
1698 specify identification strings to be sent to servers.
1699 Add OID for the new ExtLite attribute set.
1701 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1702 as requested/supplid by Ere Maijala <ere@atp.fi>
1704 For generic frontend server, reverse the order of
1705 "toolkit-supplied / application-supplied" strings sent as implementationId,
1706 Name and Version. Also, remove the spaces around the slash. This brings
1707 the GFS in line with the behaviour of ZOOM-C on the client side.
1709 Add function ZOOM_scanset_display_term.
1711 yaz-client shows scan displayTerm if present.
1713 Utility yaz-iconv is now installed by default along with the man page
1716 Extend configure check for OpenSSL to use pkg-config where available (such
1719 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1720 server to specify uid/gid/mask for socket using the format
1721 unix:[user=uid,][group=gid,][umask=mask,]file=path
1722 If file= is omitted the existing format is assumed, e.g.
1724 in which case the mask is 0666 (rw for everybody).
1726 Major restructure of YAZ source. All source in libyaz is in src directory.
1727 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1728 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1730 Added man page for utility yaz-marcdump (used to be called marcdump).
1731 yaz-marcdump is installed by 'make install'.
1733 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1734 of incoming package failed.
1736 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1738 Change prototype of odr_perror: add const to message string.
1740 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1742 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1743 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1744 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1745 DNS lookup. There should not be any compatibility problems with this
1746 assuming that blocking=1 or 0 is used.
1748 Fix bad reference in UNIX comstack in function cs_addrstr.
1750 Fix for compilation on AIX.
1752 The generic front-end server (server/seshigh.c) now supports returning
1753 Init diagnostics to the client in User-information-field, in
1754 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1757 --- 2.0.4 2003/09/04
1759 Allow any CQL relation (not just all,any,exact,scr).
1761 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1762 that features the same UI.
1764 Implemented command update0 in YAZ client which is equivalent to
1765 update but uses old of Ext Update ASN.1.
1767 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1768 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1769 Previously no OID was used for this info.
1771 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1772 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1773 returns 'malformed search term' otherwise.
1775 SortResponse member resultCount now set to NULL in sort handler of
1778 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1781 Add three new utility functions for translating OIDs between various
1782 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1783 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1784 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1785 char *oid_to_dotstring(const int *oid, char *oidbuf);
1786 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1788 Reverted modifications for ES Update definition for z_IU0Update
1789 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1790 is back to YAZ 2.0.2.
1792 String value attributes for CCL parser.
1794 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1795 which their FirstSearch server returns in Init responses, sometimes
1796 carrying useful diagnostic information when Init fails. This has the
1797 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1798 "z39.50/oclcui.asn", where its definition is somewhat different from
1799 what OCLC document on their web-site, as required to interoperate with
1802 Support for anonymous authentication in yaz-client. Use the command
1805 * Fix the OID of the Index Data-local "admin" Extended Service from
1806 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1807 the 1000, which indicates a locally-defined OID, was a mistake.
1809 --- 2.0.3 2003/06/20
1811 Fix CCL directive @case handling so that it affects string match for
1812 both CCL keywords and qualifiers.
1814 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1815 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1816 Decoder has been updated with ASN.1 changes as listed in
1817 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1818 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1819 z_IUUpdate, remains unchanged.
1821 ZOOM_record_get may now return a record in a specific character set.
1822 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1823 "from" is the character set of record as returned by target. "to" is
1824 the character set to be returned. If omitted, "to" is UTF-8.
1826 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1828 New ODR utility, odr_getelement, which returns name of element for
1829 which encoding/decoding failed.
1831 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1832 in cases where a required element was omitted.
1834 Bug fix: some MARC8 sequences were not converted.
1836 New ZOOM option "step" which specifies number of records to be
1837 retrieved in one chunk. Used in conjunction with "start" and "count".
1839 SRW support for yaz-client. Use scheme http: to use it, e.g.
1842 yaz-client no longer does (un)intelligent character set conversions
1843 by default. Can be enabled with charset and marc_charset commands.
1845 xmalloc trace fix for 64-bit systems such as DEC alpha.
1847 Solaris 2.6 compile fix.
1849 New function, cql_strerror() translates SRW error codes, as returned
1850 by cql_transform_error(), into human-readable English strings. Used
1851 in yaz-client diagnostics when appropriate.
1853 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1854 converts it into a type-1 query which is sent to the server. This
1855 makes CQL available for use with all Z-servers, as opposed to the tiny
1856 minority that can handle CQL queries themselves.
1858 --- 2.0.2 2003/04/28
1860 New Debian package layout similar to the Redhat Package layout.
1862 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1863 and search result respectively.
1865 --- 2.0.1 2003/04/25
1867 Redhat package is now several packages: libyaz (runtime libraries),
1868 libyaz-devel (development and documentation, and yaz (utility programs).
1869 Package spec file by Morten Bogeskov.
1871 New member 'schema' in struct bend_fetch_rr which the name of requested
1872 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1873 handler MAY set this to reflect the schema of the returned record.
1875 New member 'display_term' in struct scan_entry. GFS now sets member entries
1876 and allocates scan entries to be filled by user scan handler. In previous
1877 version, entries member was allocated by the scan handler. That still works,
1878 but the GFS will ignore member display_term - assuming it was NOT set by
1879 the handler. The fact that the GFS now allocates the entries both allows
1880 for new members and makes a scan handler easier to write.
1882 Fix CQL lex buffer overflow.
1884 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1885 SRU default recordPacking is string.
1887 SRU protocol support for frontend server.
1889 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1891 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1893 Added scan for the ZOOM shell (zoomsh).
1897 * String Identifers for Schemas (Amendment 5).
1898 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1899 Old definition for schema
1900 Odr_oid *schema; /* OPT */
1905 Z_InternationalString *uri;
1906 #define Z_Schema_oid 1
1907 #define Z_Schema_uri 2
1910 * resultCount parameter to Sort Response (Amendment 1).
1911 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1913 Support for SRW 1.0 over HTTP. This is an optional feature and
1914 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1917 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1918 on the same port. SRW SearchRetrieveRequests are mapped
1919 to bend_init,bend_search,bend_fetch,bend_close.
1921 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1923 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1924 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1926 ZOOM connections are SRW based if schem http is used for hostname
1927 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1928 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1930 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1931 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1932 distance=n, order=true/false, relation=le, prox unit=word. If
1933 n is omitted, distance 1 is used.
1935 Fixed problem with C compiler include path in wrong order.
1937 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1938 on Solaris. Patch from Ko van der Sloot.
1940 New MARC decode API. All new functions operate on a yaz_marc_t
1941 handle. The most important new functions are: yaz_marc_create,
1942 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1943 decode and destroy respectively. Decoder can produce formats
1944 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1945 include/yaz/marcdisp.h.
1947 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1948 to UTF-8, UCS-32, wchar_t or Latin-1.
1950 * Prototypes for yaz_iconv_-functions moved to separate header
1951 include/yaz/yaz-iconv.h.
1953 Make a few private functions 'static' in unix.c. This prevents
1954 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1956 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1957 are set when Init Response is received.
1959 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1960 but returns diagnostic set as well.
1962 New function yaz_strerror which is a portable wrapper for
1963 strerror/strerror_r/GetLastMessage.
1965 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1966 is returned for MARC. If type is "oai", then OAI MARC is returned.
1968 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1971 --- 1.9.2 2002/11/26
1973 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1975 Fix bad race conditions on SIGTERM and terminate gracefully in
1978 Move retrieval (data1) module to Zebra since nobody seems to be
1981 Add GRS-1 render for ZOOM using same format as yaz-client.
1983 --- 1.9.1 2002/10/05
1985 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1987 Fix broken ESpec handling in data1 module.
1989 SGML reader parses comments and makes them part of the data1 tree.
1991 Added several type casts so that YAZ compiles as C++ code.
1993 ZOOM didn't handle PDU encoding failures properly.
1995 Added more Bib-1 diagnostics (approved extensions).
1997 GNU configure: better check for iconv.
1999 More portable use of accept, getpeername. Check for socklen_t. Use
2000 int/size_t if socklen_t is not defined.
2004 PQF parser rejects bad queries - including those with extra
2005 characters in them. PQF parser used to silently ignore that.
2006 Cleaner API for PQF added, which allows you to get detailed
2007 error information for bad queries (see yaz/pquery.h).
2009 Fixed bug in ZOOM_record_get for type "database".
2011 Implemented mini iconv library supporting conversions between
2012 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2014 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2016 --- 1.8.9 2002/08/20
2018 Fixed ZOOM C record cache so that preferredRecordSyntax and
2019 elementSetName is used to check for already fetched records.
2021 --- 1.8.8 2002/08/02
2023 Added three members in bend_initrequest structure to facilitate
2024 character set negotiation.
2026 Fixed a bug in frontend server that could cause indefinite
2027 loops under rare conditions.
2029 Revised character set utilities (charneg.h) so that encoding
2030 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2032 For PQF, directive @term <type> sets term type for Scan/Search.
2033 Here <type> is general, string, numeric, null. The term type
2034 is inherited - just like @attr.
2036 New call odr_set_charset that sets character set conversion for
2037 international-strings on a ODR stream. Prototype is:
2038 int odr_set_charset(ODR o, const char *to, const char *from);
2039 The InternationalString is still represented as C string in YAZ
2040 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2041 won't). On the protocol level, you can use any encoding.
2043 Support for UNIX sockets in ZOOM.
2045 Solaris recv sometimes returns errno == ENOENT. It is treated as
2046 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2048 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2049 both client and server. Code by Morten Bogeskov.
2051 --- 1.8.7 2002/05/22
2053 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2054 that they can be used directly from Visual Basic. You must recompile
2055 your windows APP if you're using ZOOM.
2057 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2058 Commands "lang" and "charset" sets language and character set respectively.
2059 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2060 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2062 Attributes from multiple CCL fields may be OR'ed rather than merged
2063 using directive "@field or". Fields are still merged by default -
2064 equivalent to "@field merge".
2066 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2069 Fixed bug in zget for parameter ExtendedServicesResponse.
2073 --- 1.8.6 2002/03/25
2075 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2077 Client displays USR.1:SearchResult-1 (hits per term).
2079 Additional Search Info for search in Generic Frontend Server.
2081 Fixed CCL parsing of "field=s".
2083 WIN32 installer - using the excellent NSIS software from nullsoft.
2085 Fixed CCL parsing of "field = - <number>".
2087 Added function yaz_marc_decode that decodes MARC for line mode
2088 display or XML (similar to that used by JZKit).
2090 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2091 Z39.50. But ISO/ILL was, however.
2093 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2094 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2096 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2097 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2099 --- 1.8.5 2002/02/03
2101 New YAZ client features: Command completion and new commands:
2102 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2103 Code provided by Jacob Poulsen.
2105 New call oid_trav, that visits all registered OIDs via callback.
2107 Function ZOOM_record_get now returns const char pointer rather than
2108 void pointer. It saves a lot of type casts.
2110 For YAZ client, command "auth" now allows you to set authentication
2111 in IdPass style. It is enabled when three tokens are given - order
2112 is user, group and password.
2114 Fix memory leaks in MARC record handling for ZOOM.
2116 New option for YAZ client, -k <kilobytes> that sets
2117 maximum record size. Similar to -k option for generic frontend
2118 server and yaz-ztest.
2120 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2122 Prefix query parser reports "fail" when bad attribute set is given.
2124 Fix in MARC decoder. Proximity logging. Fix for attribute set
2125 in scan handler for server. Patches by Shigeru Ishida.
2127 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2130 Configure option --with-openssl=<dir> now works when a directory is
2131 specified. Patch provided by Morten Bogeskov.
2133 New option for YAZ client, -u <auth>, that sets authentication.
2135 ZOOM fix: error information was sometimes "missing", since error
2136 was cleared/reset too when it shouldn't.
2138 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2140 --- 1.8.4 2002/01/04
2142 Scan for ZOOM API. New object ZOOM_scanset. New functions
2143 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2144 ZOOM_scanset_destroy.
2146 New ZOOM function, ZOOM_connection_last_event, that returns type
2147 of last event (such as "receive data", "send data", "apdu received",
2150 New ZOOM option, schema, that specifies schema for retrieval.
2152 New CCL feature. Qualifiers can be aliases for one or more
2153 other qualifiers (if more than one is given, OR is used).
2155 ZOOM uses named result sets if target supports it.
2157 Two new YAZ client commands: . (dot, which sources a script of YAZ
2158 client commands), and ! (to execute shell command.). Implemented
2161 Working on Debian packages.
2163 --- 1.8.3 2001/11/19
2165 YAZ client enables named result sets only if target supports it.
2167 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2169 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2170 with key="host" to get same result.
2172 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2173 Function Z3950_resultset_record(s) returns references to records
2174 "owned" by resultset. To become owner use Z3950_record_clone.
2176 Function z_ext_record handles Extended Services. Thanks to
2179 --- 1.8.2 2001/11/12
2181 CCL Parser fix: ignore token comma when dealing with and-lists.
2183 Documentation updates for COMSTACK.
2185 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2186 Changed prototype Z3950_records. For some functions, int parameters
2187 were changed to size_t.
2189 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2192 New MARC decode/display function, marc_display_exl, which properly rejects
2193 non-ISO2709 records. YAZ client uses it.
2195 --- 1.8.1 2001/10/29
2197 Fix bug: local attribute set wasn't set correctly in PQF strings.
2201 * Old Z39.50 codecs no longer supported.
2203 Added ZOOM C binding. See http://zoom.z3950.org/
2205 Renamed states for COMSTACKs to avoid confusion with events.
2207 Implemented cs_look and proper cs_rcvconnect.
2209 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2211 Configure detects POSIX threads on OpenBSD.
2213 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2214 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2216 When error is returned from present handler, non-surrogate diagnostic
2217 is returned in present response (and fetch handler is no longer called).
2219 * Minor adjustments to pquery parser (PQF). Token characters may be
2220 escaped by using backslash (C-style).
2222 PQF parser allows string attribute values to be specified. For @attr,
2223 non-numeric characters after the equal-sign are treated as strings
2224 (e.g. @attr 9=title).
2226 CCL trunction character may be defined (@truncation in file)
2228 * function zget_ExtendedServicesRequest sets waitAction to
2229 waitIfPossible (was wait).
2231 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2234 CCL operator names may be set in field definition files (CCL_bibset).
2235 See ccl/bib1 for an example.
2237 Fixes in ASN.1 compiler for C++ compatibility.
2239 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2240 and "op_or" to avoid conflict with C++.
2242 Fixed problem with GNU readline detection on Redhat 7.0.
2244 Added step-size for Scan backend handler.
2246 Fixed bug that made the frontend server crash when no attribute
2247 set was specified for scan.
2249 Front-end server automatically switches to original working directory
2250 when installed as an NT service. Previously -w had to be specified to
2253 Added extended attributes for retrieval module (data1), so that data1
2254 records carry d1_readXML/SGML attributes. d1_read also supports
2255 null-data rules ( <tag/>)
2257 On UNIX when POSIX threads are available, a separate library libyazthread
2258 is created. Programmers should link with that library and the yaz library
2259 when using threads. The reason for the split was that some applications
2260 on Linux, such as Apache, doesn't work well when using shared objects that
2263 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2264 (or any frontend server) in SSL mode by specifying ssl: followed by
2265 address. Only tested on UNIX.
2267 Added feature for CCL module. Virtual structure s=al or s=ol generates
2268 and-list and or-list respectively instead of phrase search.
2272 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2273 log_mask_str. This was done to avoid name conflicts with other libraries
2274 (such as other PHP extensions).
2276 Added raw OID member for preferred record syntax (request_format_raw)
2277 and returned record syntax (output_format_raw) for backend fetch method.
2279 Config file yaz-config now accepts options so that it returns specific
2280 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2282 Shared library support for UNIX using GNU libtool.
2284 * Modified backend interface. Request/Response struct's replaced by
2285 one read/write C struct. For example bend_fetchrequest and
2286 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2287 Every handler - even search has to be registered in bend_init
2288 handler. This means that the YAZ library no longer refers to
2289 external functions and it makes it possible to make the whole
2290 thing a single DLL/SO.
2292 Added Segment handler for backend server.
2294 Added Zmbol/Zebra administrative functions to YAZ client.
2296 Threaded frontend server on UNIX (when POSIX Threads are available).
2297 Starting the server with option -T enables multi-threading.
2301 Added configure option --enable-comp/disable-comp to control use
2302 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2303 located in sub directory asn.
2305 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2306 in ${exec_prefix}/bin along with the other programs yaz-client and
2309 GNU automake used to maintain makefiles.
2311 Added several OID's.
2313 Changed retrieval module so that we can load records with no abstract
2314 syntax defined. Tagpaths in these records are fully composed of string
2317 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2321 On UNIX, the generated makefile now supports a proper 'make install'.
2322 The prefix can be set via GNU configure to set the install location
2323 (default is /usr/local).
2325 * YAZ programs client and ztest were renamed to yaz-client and
2326 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2327 locations, such as /usr/bin,/usr/local/bin,etc.
2329 * YAZ Header files were moved from include to include/yaz. YAZ Header
2330 files are referred to as include <yaz/log.h> rather than <log.h>.
2331 The YAZ include path (-I ..) is therefore the same as before. Programmers
2332 should update their #include statements or use -Ipath/include/yaz
2333 instead. The main motivation for doing this change is that YAZ header files
2334 can be installed in "standard" locations /usr/include,/usr/local/include
2335 without introducing conflicts, since ALL YAZ header files are stored
2336 in subdirectory yaz (under /usr/include for example).
2338 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2339 rather than project/workspace files. We switched because project files
2340 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2343 Changed name of logging function, logf, to yaz_log, to prevent name
2344 clash with some math-log functions. The YAZ header log.h defines logf
2345 to yaz_log (#define) so there should be no incompatibilities by this
2348 Added bend_start/bend_stop handlers for server. These handler are
2349 called on start/stop of server. For windows they are called whenever
2350 a service is started/stopped.
2352 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2353 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2354 in util/yc.tcl. The auto-generated C code structures are, in a few
2355 cases, incompatible with the old decoders. There are differences in the
2356 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2357 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2358 The preprocessor variable ASN_COMPILED is defined when the compiled
2359 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2360 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2361 wish to use the old encoders/decoders you can specify --disable-yc
2364 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2365 version so that it supports both new - and old version of DB Update
2367 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2368 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2369 change. The name parameter can be set to 0 in which no name is specified
2370 for the construction. The macros odr_implicit and odr_explicit sets name
2371 parameter to zero for the construction involved. New macros
2372 odr_implicit_tag and odr_explicit_tag are similar to the others,
2373 except that a name parameter is added. For programmers' that don't use
2374 ODR they probably only need to change the call to z_APDU and z_External.
2376 Added access control facility by interfacing the TCP wrapper library.
2377 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2378 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2379 name of the daemon and enables the access control as specified in
2380 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2382 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2383 den Dool <H.M.vdnDool@kub.nl>.
2385 Added reference ID parameter to most functions in server API - refer
2386 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2388 Changed name of ccl library to libccl.a (was ccl.a).
2390 Fixed bug in decoder for Explain (Category TargetInfo).
2392 Added support for GNU readline in client. Thanks to Jacob Poulsen
2393 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2395 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2396 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2397 IMPLEMENTATION! This change was made to the development version before
2398 the ZIG decided to retract the amendment. If any users MUST be
2399 compatible with the original Update definition, PLEASE CONTACT US, and
2400 we will include a separate definition corresponding to the old Update
2401 ES. Note that because of the change to the ASN.1 of the
2402 TaskPackageRecordStructure we cannot define a single structure that
2403 will support both versions.
2405 * Added const modifier to buffer parameter for some ODR/BER encoding
2406 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2407 completeWAIS, odr_dumpBER.
2409 Fixed bug in client.c which caused a crash when a scanResponse didn't
2410 contain positionOfTerm.
2412 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2413 * will cause an error in a client if a non-YAZ target sends both a
2414 * list of Scan entries and non-surrogate diagnostics.
2416 Retrieval module enhancements. Tag sets may be typed in the reference
2417 to it. From the .abs-file the "tagset" directive takes a third optional
2418 integer type for the tag set referenced. From a .tag-file the "include"
2419 directive takes a third optional type as well. The old "type" directive
2420 in the tag set itself is still recognized but acts as the default type
2423 Backend interface change. Individual Scan terms returned from bend_scan
2424 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2425 in include/backend.h.
2427 Retrieval module enhancements. Multiple tag sets and attribute sets may
2428 be specified in abstract syntax specs. Revised the error/warning for
2429 logging messages reported by the retrieval module when reading the
2432 Object Identifier system (oid_..) changed. The API is backwards
2433 compatible but the oid-routines now allocates new OID's when needed.
2434 Raw OID's may be specified in oid_getvalbyname.
2436 YAZ now uses GNU configure to generate Makefile(s).
2438 * Minor changes in some of the member names of DeleteResultSetRequest and
2439 DeleteResultSetResponse. See include/proto.h.
2441 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2442 and added member 'languages' in TargetInfo (which was missing).
2444 Changed the way attribute sets are handled in the retrieval
2445 module. These are now cached, just like the abstract syntaxes
2448 Changed YAZ so that it links with compiled ASN.1.
2450 Added Explain-schema definitions and mapping routines. The following
2451 Explain categories have been implemented: AttributeDetails,
2452 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2454 Fixed minor bug in Windows version of Server Library.
2456 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2458 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2460 Added EXTERNAL: UNIverse Resource Report (non-standard).
2462 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2463 ENUMERATED and SET OF.
2465 * Added 'const' to some of the char pointer arguments for the
2466 functions, data1_read_node, data1_getelementbytagname,
2467 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2470 Fixed bug in data1_insert_taggeddata - the last_child member of
2471 parent wasn't initialised.
2473 * Changed data1_read_record and data1_read_node so that the supplied
2474 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2475 doesn't refer to any parts of the "SGML"-buffer.
2477 Fixed bug in server library (Windows version of statserv_remove).
2479 * Changed code so that it compiles as C++. The type definition
2480 of Odr_fun which is a member of Odr_arm was changed. The result is,
2481 that an explicit typecast is needed for the fun pointer when
2482 using Odr_arm - as in:
2483 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2485 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2487 Implemented the new structured date and time definition as approved
2488 by the ZIG. Added schemaId element to the specificTag in Espec-1
2489 (also approved at the last ZIG). Thanks to RVDM.
2491 Added some Object identifiers (RVDM).
2493 Changed the Update Extended Service (RVDM).
2495 Added command "refid" to client which specifies referenceId for
2496 the following requests.
2498 Implemented extended service handling for server. See ztest.c
2499 for an example as well as backend.h. New handlers are registerd
2500 in the Init handler.
2502 * Changed interface for sort in server.
2504 Added new members to statserv_options_block. It allows a server
2505 to read options from another source than just the command line. Thanks
2506 to Charles Woodfield.
2508 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2509 renamed to zboolean. Some C++ compilers complained about the name.
2511 Minor changes to gils.abs. Added index 's' (sort) on title
2512 and date/time-last-modified.
2514 --- 1.4pl2 1998/1/30
2516 Fixed bug in server library regarding inetd mode (-i). This bug
2517 was introduced by release 1.4.
2519 --- 1.4pl1 1998/1/29
2521 Added sort facility in client and backend server interface.
2523 Fixed problem with dependencies in Makefile(s).
2525 Fixed bugs for encoders/decoders of extended services and
2528 Implemented sub-tree feature for schemas. Sub-trees are
2529 referenced in *.abs-files. See explain.abs for an example
2530 of the use of this feature.
2532 Modified bib1.att; local attributes for ANY didn't include
2533 ANY itself (only affects use of the retrieval module).
2535 Fixed bug in plain SGML reader in function data1_read_node:
2536 tags with prefix "var" was incorrectly interpreted as variants.
2538 Added feature "sub-schemas" to enable references to - and definitions
2539 of - group of elements.
2541 * Removed member parent from type data1_element (in data1.h).
2543 Implemented function odr_nullval() that returns the value of
2546 * Removed member num_children from data1_node (in data1.h).
2548 Made NT service interface part of the server library. The
2549 function statserv_main uses the NT service when required and
2550 calls the statserv_start / statserv_close routines.
2552 Routine zget_SearchRequest and zget_PresentRequest fills
2553 resultSetName/Id member with "default" instead of "Default".
2555 Fixed memory leak in server. Request queue member wasn't freed.
2557 Fixed nmem_exit so that memory is freed.
2561 Revised the CCL parser utility to be thread safe.
2563 Added function, oid_ent_to_oid, to replace the function
2564 oid_getoidbyent, which is not thread safe.
2566 * Added nmem_init and nmem_exit to initialize and release
2567 NMEM resources. Function nmem_init should be called once in the
2568 initial thread before NMEM/ODR is used. statserv.c and client.c
2569 have been changed accordingly. The change was necessary to make
2570 NMEM thread safe. The NMEM memory pool is shared amongst threads
2571 in a process. Unix-based applications will still work fine without
2574 Added NT Services interface for the the Z39.50 (statserv) Server.
2575 Refer to the ztest.c source on the usage.
2577 Windows 95/NT port using MSVC5.0. Project files are included in the
2580 * Defined new 'global' handle for the retrieval (data1) system. The
2581 new handled, data1_handle, describes the state of the data1 system.
2582 This handle is passed as first argument to virtually all
2583 data1 related routines. The functions data1_create and data1_destroy
2584 creates and destroys a data1 handle respectively.
2586 Added ODR encode stream member to all backend request structures
2587 init, search, scan etc. This stream should be used to allocate all
2588 memory used for the response when thread safe operation is needed.
2590 Changed the comstack utility, cs_addstr, to be thread safe. The
2591 returned hostname string returned by the function is now part the
2594 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2595 function. The cs_straddr takes a COMSTACK handle as argument, so this
2596 function must be used after cs_create and before bind/connect.
2597 This function is thread safe.
2599 Moved test server to 'ztest' directory - generic server code still
2600 in 'server' directory.
2602 Made prefix query (pquery.c) utility thread safe.
2604 Added new function modifier YAZ_EXPORT to 'export' public DLL
2605 functions when using windows (see include/yconfig.h).
2607 Added definitions to the OID database (util/oid.c) (RVDM).
2609 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2611 Added call to ccl_rpn_delete in client program.
2613 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2614 release of RPN structure.
2616 Added support for C++, headers uses extern "C" for public definitions.
2617 With input from RVDM.
2619 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2620 Thanks to Ronald van der Meer (RVDM).
2622 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2624 Added support for private extensions to the OID database
2625 (oid_setprivateoids()). Thanks to RVDM.
2627 Added optional, physical ANY (key replication)
2629 Fixed null-reference problem in GRS-1 output filter.
2631 Proximity operator added to Prefix Query Format (PQF).
2633 In test client command "base" accepts multiple databases.
2635 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2639 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2641 Smallish bug-fixes in the new encoders/decoders (explain).
2643 Bug fixed in DeleteRequest.
2645 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2647 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2649 Added SOIF syntax (using private OID for now) to retrieval module and client.
2651 Added Update extended service.
2653 Added SearchResult-1 additional info structure.
2655 Added optional CCL (ISO8777) interpreter as separate module. Available
2658 --- 1.2 1996/6/10 (1st anniversary release)
2660 Added Summary record syntax. Lightly tested.
2662 Added OPAC record syntax. Untested.
2664 Added ResourceReport service encoders/decoders. Untested.
2666 Fixed bug in z_Unit - wrong tagging on unitSystem.
2668 Fixed bug in the DiagRecs decoder.
2670 Added options for max PDU size and session timeout to frontend-server.
2672 Added documentation of query-language parsers and other supporting utilities.
2674 [frontend-server] Added Attribute set to the bend_scanrequest API.
2676 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2677 surrogate diagnostics were generated.
2679 [retrieval] Allow multiple local values for attribute.
2681 [retrieval] Allow multiple attributes per element in .abs files. index type.
2683 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2685 --- 1.1pl2 1996/4/10
2687 Minor changes, mostly specific to Zebra's requirements (retrieval)
2691 Repaired bug in frontend server when running multiple listening
2692 endpoints in dynamic mode.
2694 z_External() now won't break if a known, ASN.1 value comes encapsulated
2695 in an octet-string. The value will pass through unmodified in an Odr_oct.
2697 Added a bit of code to the demo client to decode & display
2698 ASN.1-structured records represented in the octet-aligned branch of
2699 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2701 Added z_ext_getentbyref() to the ASN module. Doc updated.
2703 * Completed the SCAN definition in the ASN module. This may break SCAN
2704 code based on older YAZ-versions at compile-time. The fix is easy -
2707 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2708 under the SCAN definition. Remember to initialize this, server-people.
2710 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2711 that this does not extend to ODR and ASN.
2713 Comstack allows insertion of established socket (primarily for
2714 inetd-operation of servers). Doc updated.
2716 Front-end server can now start from the inetd in TCP mode. Doc
2719 --- 1.0pl4 1996/1/24
2723 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2724 the rank and record number.
2726 Adjustments to the frontend server.
2728 Fixed diagnostic BER dumper. It ignored the file argument.
2732 Various changes to retrieval module.
2734 Changed the union discriminators of the protocol files from enums to
2735 ints paired with #defines.
2737 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2740 *Changed operator in the RPN structure to 'roperator', again to avoid a
2743 Fixed problems in Explain decoders/encoders.
2745 --- 1.0pl2 1995/12/6
2747 Memory bug in log module fixed.
2749 --- 1.0pl1 1995/12/5
2751 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2753 Bug in Explain DatabaseInfo module fixed.
2755 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2759 The shift to v1.0 signals that we now consider the *core* functionality
2760 of YAZ reasonably stable (the core being more or less equivalent to
2761 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2762 tested (Explain not at all - though that will happen soonish).
2764 Minor changes to code to support Windows port.
2766 Various minor changes after we're getting to use GRS-1 & co. more.
2768 Added Espec-1 format.
2770 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2771 of the protocol and it cannot be selected when encoding (maps into 'string'
2772 when decoding). Needed to talk to some servers.
2774 Demo client can request simple element set names.
2776 Added Diagnostic Format encoders/decoders.
2778 Added simple Close handling to frontend server (no hooks for resource
2779 reporting yet), and demonstration client.
2781 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2783 --- 1.0b3 1995/08/24
2785 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2786 handled incorrectly when records were requested in the searchResponse. This
2787 will only affect you if you use the frontend-server.
2789 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2790 Test-client will ask for and print GRS1. Ztest will return dummy records
2793 Added Explain encoders/decoders to the service-level API. Untested.
2795 Added Extended Services: Item Order encoders and decoders to the Service-
2796 level API. Untested. We could use a recent copy of the pertinent bits
2797 of the ILL protocol to add those bits.
2799 Added diagnostic format 1 encoders/decoders to the service-level API.
2802 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2803 odr_cons.c, which causes a more correct output.
2805 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2806 was always set to 0 when no records were requested in the searchRequest.
2808 * Added better external-handling. This shouldn't harm old code that
2809 *encodes* externals. It can break code that looks for a
2810 'single-ASN1-type' representation, since those types that are known
2811 are now decoded immediately. Look at the SUTRS sample code in
2812 seshigh.c and client.c. Documentation updated.
2814 Handling of structured records in bend_fetchresponse. Length -1 marks
2815 structured record, type is deduced from format field.
2817 --- 1.0b2 1995/06/27
2818 Fairly quick maintenance release to add SUTRS support.
2820 Fixed handling of SUTRS records in the demonstration client.
2822 * Added format field to the bend_fetchrequest and bend_fetchresponce
2823 structures of the backend API (frontend server). When the record is
2824 returned, the value of the format field is mapped to an OID. The
2825 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2826 of the record. The special value VAL_NONE in the bend_request means
2827 that no specific format was requested by the client. Documentation
2828 updated accordingly. Test server (ztest) will return a fixed dummy
2829 SUTRS record if your client requests SUTRS.
2831 Documentation updated accordingly.
2833 You can now set external libraries and RANLIB support in the top-level
2837 First public release.
