3 Z39.50 facet support. Facet specifications are passed for search in
4 other-information with ASN.1 as defined in facet.asn and OID
5 .10.1000.81.5 . Facets are expressed as an Attribute list as known
6 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
7 3 is limit (number of entries to get in response). yaz-ztest returns
8 dummy facets if a client asks for them.
12 CCL fixes: bug 2895 and bug 3539.
14 GR1-display: add comma in display - was removed by mistake in
17 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
19 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
23 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
24 result set from a connection. The result set will be on its own
25 thereafter; no operations on it will perform retrievals from a target.
26 Only cached copies are returned.
28 ZOOM C:fix case for HTTP servers responding with Connection:close.
29 Ensure that if there is a current task it is resumed (like fetching
30 more records in a result set) . Bug #3484.
32 PQF parser: use odr_atoi for Odr_int (not atoi)
34 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
35 values that contain any non-digits are treated as string attributes
36 (previously decoding only checked for leading character ([0-9]). PQF
37 encoding: attribute string values are not surrounded by double-quotes.
41 New utility for managing threads - thread_create.h.
43 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
44 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
45 but YAZ' implementation do.
47 Fixes for yaz_cond-functions on Windows 7.
49 DLL export more symbols.
51 zoomsh: show record do NOT render opac.
53 Remove *.la files from Debian and RPM packages.
57 Debian package libyaz-dev depends on libgnutls-dev again (was
58 removed in YAZ 4.0.6, but due to Libtool it is still needed
59 even though yaz-config do not list libgnutls libs).
61 ZOOM: Use only one WRBUF for returning string results for
62 ZOOM_resultset. Reduces memory usage for ZOOM in general.
64 ZOOM: ZOOM_connection do not use a shared pointer to
65 ZOOM_resultset after ZOOM_resultset is destructed by
66 user. Reverts to YAZ 4.0.4 behavior.
70 record-conv: fix problem with at least one XSL conversion -
71 due to probably incorrect usage of XML XSL documents.
75 Fix yaz-config for static mode and the use of SSL (gnutls).
79 Forward decl timeval struct in mutex.h and gettimeofday.h.
81 yaz-config: fix 'static' mode linking.
85 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
86 are wrappers for pthreads or Windows. For Windows these are put in
87 a separate DLL: yaz_cond4.
89 libyaz.la (whole source) is compiled with thread. If thread support
90 is enabled enabled, all source of YAZ is compiled with treading support.
91 This allows core utilities such as yaz_log to use thread facilities.
92 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
93 thread utilities. This commit moves mutex utilities (mutex.c) from
94 libyaz_server.la to libyaz.la.
96 yaz-json-parse displays leading text until error.
100 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
101 patch from Giannis Kosmas.
103 SRU: no longer URL encode SRU database. The URL for an SRU server is
104 a URL and such is alreeady encoded - at least when given with leading
105 http:// or https://. This reverts behavior to YAZ 3.0.50.
107 Support for new MARC XML notation TurboMARC which like MARCXML is a
108 complete representation of MARC/ISO2709.. This one, however, is more
109 compact and allows for faster processing with XSLT. TurboMARC can be
110 used in the marcdisp.h API, from the yaz-marcdump utility and from
113 yaz-ztest can be configured - via the database - to perform certain
114 delays when it performs operations search, present and single record
115 fetch. This allows testers to make yaz-ztest act as a real or even slow
116 Z39.50 server. Refer to the yaz-ztest man pages for details.
120 wrbuf_destroy allows NULL WRBUF passed to it.
122 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
124 Add ZOOM_connection_close.
126 No fixed size buffers for ZOOM shell - bug #3257.
128 tstodr: make it work on s390 platform.
130 New icu iterator-functions. The new icu_iter-functions makes it possible
131 to use ICU chains from many threads.
133 yaz-client: better syntax check for show command.
137 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
140 New simple local-file XML include facility which allows file glob-patterns.
141 Refer to yaz/xml_include.h.
143 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
146 ZOOM_record_get supports new parameter "format" which makes it format XML
149 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
150 JSONText in ECMA-262) is JSONValue, not JSONObject.
154 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
155 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
157 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
158 POSIX/Unix builds .so with major version 4.
160 Remove old LOG_-defines from log.h. They have been obsolete and
161 undefined by default for the last 5 years.
163 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
165 GFS: Remove socket (int *fd) from search_rr handler. The socket
166 descriptor ptr is a facility that allowed a search handler to supply
167 a socket which would serve as a callback - when search was complete.
168 This facility has now been in use for years.
170 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
171 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
172 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
173 returns 'const char *' rather than 'char *. The returned string is
174 read-only and should not be modified by applications. COMSTACK cs_close is
175 now a void function - it no longer returns int. No applications check for
176 the value and the implementations has always returned 0.
178 ZOOM: use size_t for scan hit counts and str size. Functions
179 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
180 occ (hit count) and len (string length) are now of type size_t pointer
181 rather than int pointer. This is to be able to represent large hit counts
182 and to also just to use the proper type for string length (strlen result).
184 New JSON parser. Refer to include/yaz/json.h .
186 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
187 Used to be int in some cases. Many wrbuf_-functions used to return an int
188 indicating some length.. These return values were never used. And so they
191 ODR: odr_malloc, odr_total now takes size_t for size.
193 clone_z_type: fix leak; occurred for encoding failures.
195 --- 3.0.52 2009/12/03
197 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
198 bug was introduced in 3.0.51.
200 --- 3.0.51 2009/12/02
202 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
204 tcpip comstack: fix leak for getaddrinfo.
206 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
207 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
208 Decoding of SRU "path" database is performed by private function
209 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
210 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
212 yaz-client: honor base command for SRU. Change when database setting
213 is applied for SRU and ensure it is kept when a connection is reset.
214 Change also the way errors are displayed or SRU (decoding of packages).
216 --- 3.0.50 2009/11/02
218 Add support for extra request / response data for SRU codecs and GFS.
219 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
220 for extra data response buffer and length. For the GFS, both request
221 and response data (XML) is carried in extra_args and extra_response_data
222 for the search handler. Patch by Ko van der Sloot.
224 ZOOM: For queries that cannot be converted to the specified rpnCharset,
225 ZOOM now returns a diagnostic on the client-side ('invalid query' /
226 10010). This fixes bug #2113.
228 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
229 cmdfile included a 'quit' command that would result in a memory violation.
231 --- 3.0.49 2009/10/01
233 Make a number of functions defined in xmlquery.c static. These have
234 never been declared in a public header file (yaz/xmlquery.h) and was
235 made public by mistake.
237 Improve speed of character conversions (iconv utilities). This makes
238 conversions from MARC-8 faster.
240 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
241 unless type desired is "raw". This will prevent type "xml" from
242 returning ISO2709 .. Which obviously can not be XML parsed.
244 Fix memory leak in ZOOM that would occur if option apdulog was used
245 on a re-used connection.
247 Frontend server logs HTTP requests.
249 Frontend server now sends Z39.50 close when it times out (sesssion has
250 been idle for too long). Versions 2.0.30 and earlier also sent close.
251 But due to a mistake this was disabled in all versions after that, i.e.
252 the server would just close the socket immediately.
254 yaz-client emits a better message when receiving an unrecognised
255 userInformationField.
257 Skip zero-length subfields when decoding ISO2709. This rare case happens
258 if a record has two FS characters in a sequence. Without this patch
259 there would be a reference beyond char array in using_code_len fragments
262 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
264 --- 3.0.48 2009/08/28
266 The show command offered by the zoomsh command now takes a 3d optional
267 parameter type which is what is passed to ZOOM_record. If the type
268 argument is omitted, "render" is used.
270 RPN to CQL conv may use USE string attributes (bug #2978).
272 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
274 --- 3.0.47 2009/07/08
276 Function yaz_xml2query allows a diagnostic element in the PQF XML
277 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
278 code and additional info respectively.
280 The BER BOOLEAN is now the integral type Odr_bool which still happens
281 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
282 typedef'd to Odr_int. This is still an integral 'int', but it may be
283 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
284 ASN-1 compiler as well as programs has been updated to use the new types.
286 --- 3.0.46 2009/06/08
288 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
289 only the bibliographic record was rendered. For type=opac, an OPAC
290 record is only returned if it is present.
292 iconv: small fix for encoding of advancegreek.
294 yaz-client: avoid double display of SRU/SRW records (bug #2798).
296 yaz-client: option auto_reconnect=on really reconnects.
298 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
300 server: avoid null ptr ref for for yaz_poll errors.
302 build: fix RPM build for RHEL 5.3.
304 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
306 --- 3.0.45 2009/03/31
308 Fixed bug #2709: TCP connect returns Invalid argument.
310 Fixed compilation for mingw.
312 Honor charset for raw records (ZOOM_record_get).
314 Fixed use of errno for threaded mode that was seen on Solaris 10.
316 Fixed argument passing with blanks in value for Windows Service.
318 Disable YAZ' own log rotate by default (no 1 GB limit).
319 The variable l_max_size which specifies the log file limit is set to 0
320 (DISABLED): This is due to the fact that YAZ is most often deployed using
321 logrotate. Also YAZ can not perform log rotate because of unsufficient
322 permissions (setuid).
324 --- 3.0.44 2009/02/17
326 List supported encodings in man page for yaz-iconv.
328 Fixed missing SSL libs for --libs output
330 Re-established OID record syntax application-xml. Nobody should use it
331 but we don't want to change soname because of this symbol being absent.
333 --- 3.0.42 2009/02/02
335 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
337 Added member named_result_sets for init handler struct for the GFS. This
338 allows a server to disable named result sets.
340 Removed OID record syntax application-xml.
342 Added support for rule-based transliterator for ICU wrapper of YAZ.
344 Fixed bug #1902: yaz-icu XML output.
346 Make YAZ checks Emacs friendly.
348 BITSTRING value shows value. Bug #2346.
350 ISO2709 decoding: skip control characters from indicator data.
352 Omit sort key by default in yaz-icu's output.
354 Allow combined single char options (again) for YAZ' options function.
356 Utility yaz-marcdump got option to display YAZ version (-V).
358 Allow YAZ to use ICU 3.4.
360 Added new ICU test case which illustrates removal of diacritics.
362 --- 3.0.41 2008/12/29
364 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
366 --- 3.0.40 2008/12/29
368 For configure, using option --without-xml2 also disables Libxslt/Libexslt
371 Fixed bug #2352: yaz-marcdump crashes for certain record.
373 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
375 Added support for Danmarc2 to UTF-8 conversion.
377 Added support for ISO5426 to UTF-8 conversion.
379 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
380 implementation version.
382 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
384 --- 3.0.38 2008/11/10
386 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
387 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
389 ZOOM C now interprets databaseName option for ZOOM connection as path
392 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
394 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
396 Dummy Libxml2 types no longer defined in headers of YAZ'.
398 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
401 --- 3.0.36 2008/09/26
403 Various ODR chapter fixes.
405 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
407 Added missing source for Windows compilation, mutex.c.
409 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
411 For SRU connections in ZOOM all records up to "count" are now fetched.
413 Fixed crash in generic frontend server (and yaz-ztest) which occurred
414 in Windows due to bad error handling for Libxml2.
416 Added facility for sending arbitrary records (ASN.1 any) using
417 ZOOM C's Extended service update. Patch by Sam Reynolds.
419 New options for ZOOM C's connection, logapdu which makes ZOOM log
422 --- 3.0.34 2008/06/18
424 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
426 --- 3.0.32 2008/06/12
428 Fixed memory violation that could occur when decoding UTF-8. This bug
429 was only present in 3.0.30 of YAZ.
431 --- 3.0.30 2008/06/06
433 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
434 GNU TLS is used by default (if found).
436 yaz-ztest returns OPAC records if a client asks for OPAC.
438 Improved speed of MARC-8 encoding.
440 Added support for lossy and loss-less MARC-8 encoding.
442 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
444 Added new Windows Service wrapper (sc).
446 yaz-client's itemorder command may now send a file.
448 Fixed yaz-marcdump to allow the use of NS prefix for record element.
450 Added new function yaz_log_xml_errors.
452 Allow (but warn) unknown XML attributes in MARCXML parsing.
454 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
456 The UTF-8 to MARC-8 conversion now uses a different set of characters
457 for Greek symbols. Bug #2120.
459 --- 3.0.26 2008/02/21
461 Added yaz_daemon (daemon.h).
463 Fixed bug #2068: pkg-config trouble
465 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
467 --- 3.0.24 2008/01/28
469 Document --with-xml2 option.
471 Added OPAC XML XSD (etc/opacxml.xsd).
473 Allow glob mask for name attribute in retrieval element for the
474 generic frontend server's retrieval facility.
476 Changed yaz_poll_poll to return yaz_poll_except for all returned events
477 except POLLIN/POLLOUT.
479 Fixed error handling in cs_listen. Bug #2037.
481 --- 3.0.22 2008/01/20
483 Fixed version in yaz/yaz-version.h.
485 Fixed bug #2027: Crash when closing connection.
487 Changed configure so that ICU support is only enabled if only ICU
488 and Libxml2 is available (because the ICU chain is XML based).
490 --- 3.0.20 2008/01/15
492 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
493 is built. Only this DLL depends on the ICU runtime.
495 yaz-ziffy is no longer part of YAZ. It is distributed separately by
496 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
498 Changed license of CCL module to 'Revised BSD'. After consultation with
499 remaining members of the original EUROPAGATE consortium, we are re-issuing
500 the CCL module without a separate license. The software was developed by
501 Index Data as part of a research project. The special license was included
502 to help feed usage information back to the project consortium to support
503 project evaluation. At this time, the project consortium has long-since
504 disbanded, and the majority of the original principals have retired. At the
505 same time, we have significantly modified the software during the following
506 years, to the point where very practically no original code remains. To
507 simplify re-use of the software, we have contacted those members of the
508 consortium who could be reached, and agreed to re-issue the module as a
509 proper part of the YAZ package.
511 Tcl scripts uses /usr/bin/tclsh as preferred shell.
513 CQL closer to being version 1.2 compliant. CQL also allows free-form
514 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
517 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
518 bug could make Extended services handling crash in the ZOOM layer. This
519 bug was only present in YAZ 3.0.18.
521 --- 3.0.18 2007/12/19
523 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
526 yaz-marcdump reads and writes collection wrapped records.
528 Handle OPAC for record conversion module.
530 Fixes for ICU wrapper.
532 Allow ICU libs to be controlled with --with-icu .
534 --- 3.0.16 2007/11/12
536 Added yaz_poll which is a wrapper for select/poll. When poll is available
537 and non-buggy, it is used, by yaz_poll . This allows more than 1024
538 sockets to be in use.
540 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
541 functionality through an XML based configuration (ICU chain). This system
542 is useful for search facilities such as Pazpar2 and Zebra that needs to
543 perform tokenization of indexed material. The ICU code in a separate
544 library libyaz3_icu.a.
546 Added HTTP tunnel facility for COMSTACK, bug #1752.
547 This is a facility that allows a Web proxy, such as squid, to tunnel
548 Z39.50 traffic. This facility is "transparent" to must applications
549 using YAZ. It's enabled by using pseudo transport connect: followed by
550 the proxy address, followed by command, then follwed by he regular
551 "virtual" addresss. For example,
552 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
554 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
556 --- 3.0.14 2007/09/21
558 Fixed bad memory reference in ZOOM_record - cuased by member not being
559 initialized. This was a problem only in YAZ 3.0.12.
561 Fixed bug in conversion from MARC to XML: Non-XML characters in control
562 fields were not removed.
564 Changed the way C code is generated from codetables.xml. Made a MARC-8
565 conversion trie for each characterSet section rather than codeTable.
566 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
567 of codetables.xml from Larry Dixson, LOC. Bug #1464.
569 --- 3.0.12 2007/09/12
571 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
572 from ZOOM_record_error).
574 ZOOM C function ZOOM_record_get returns record schema for type="schema".
576 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
578 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
580 Better SRW-to-Bib-1 diagnostic mapping.
582 ZOOM C and yaz-client announces SRU version 1.2 by default.
584 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
587 Fixed in yaz_sru_decode to allow other version than 1.1.
589 --- 3.0.10 2007/08/22
591 Added support for SRU scan for ZOOM.
593 Added support for the use of the older versions or Extended Service
594 Update in ZOOM. To faciliate this, an option "updateVersion" may be
595 set to the version , 1=first, 2=second, 3=third. The third version is
596 what ZOOM C has used so far. And that, obviously, is the default.
598 Added support for CCL queries in Z39.50 queries sent to the GFS (and
599 therefore in Zebra and in SimpleServer-based applications). The new
600 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
601 qualifier file used to transform incoming CCL queries into Type-1 RPN,
602 which is passed into the back-end search callback function.
604 Added support for HTTP Basic authentication in clients: the SRU/W
605 codec encodes the username/password elements of the PDU structure
606 appropriately, and these may be set using the "user" and "password"
607 options in ZOOM-C applications (the same options that are used for
608 Z39.50 authentication).
612 Fixed bug #1208: SSL appears to be broken in ZOOM.
614 Fixed bug #1206: Libxml2 include path weirdness.
616 Added oid_name_to_dotstring.
618 Allow elementSetName to be specified for ZOOM C record update.
620 Allow waitAction to be specified for ZOOM C based for Extended Services.
622 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
623 syntax OID. Bug introduced in YAZ 3 series.
625 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
629 Fixed bug #1157: yaz-client does not read .yazclientrc from current
630 directory. yaz-client now reads commands from file given by option -f
631 if specified; then tries to read .yazclientrc in current directory.
632 Failing that, it reads .yazclientrc from user's home directory.
634 Added support for correlationInfo Note and ID for Record Update via
637 Added yaz-client command querycharset which specifies character set for
638 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
639 (termListAndStartPoint).
641 Charset ISO5428:1984 is an alias for ISO5428-1984.
643 Implemented a way to perform scan in a result set using Z39.50. This
644 is achieved by attaching the result set name in the characterInfo
645 (type InternationalString) of OtherInformation in the Scan Request PDU.
646 The result set is identified in the otherinformation by the new OID:
647 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
648 This allows for scan in result set and faceted search . Zebra did some
649 of this in the APT term using attribute type 8 and value being result
650 set. Using the OtherInformation approach for this is cleaner and easier
651 to work with in proxies and the like. This facility can be used in
652 yaz-client using new command setscan which takes a result set as first
653 argument, start position (APT) as second.
655 Changed decoding of SRU XML packed records to deal with servers that
656 have recordData with XML data with multiple root nodes. Also make
657 comparison for recordPacking case insensitive. Again, one server
658 returns "XML" where others return "xml".
660 For SRU responses allow Content-Type application/xml as well as text/xml.
664 Fixed bug in character set conversion of BER strings. Bug introduced
669 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
671 For OID class, use oid_class consistently.
673 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
676 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
677 character set for bibliographic information interchange". By Giannis Kosmas.
679 Added documentation on new OID API.
683 Changes to generic frontend server interface: added new member
684 'query_charset' for bend_initrequest structure. A backend init handler
685 should set this member to its native character set for query terms.
686 When defined, the frontend server logic will announce this character set
687 to a client if the negotiationModel bit is set by the client. All server
688 implementors are encouraged to specify this. If a backend server does not
689 specify this a warning is issued using yaz_log(YLOG_WARN,..).
691 Added CCL utility to remove terms (stop words) from resulting RPN
692 tree. This is handled by functions with prefix ccl_stop_words_ .
694 New ZOOM C option, "rpnCharset", which allows client-side conversion of
695 terms in RPN queries.
697 Clean-up the CCL API. Moved some internal structures from ccl.h to
698 private header cclp.h. Changed ccl_parser_create so that a Bibset must
699 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
700 This is replaced by ccl_parser_find_str which takes a string instead.
702 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
703 libyaz.la is the core of YAZ except the generic frontend server and
704 does not depend on POSIX threads anymore. libyaz_server.la is the
705 generic frontend server facilities and uses POSIX thread functionality
706 if available. The libyaz.la no longer depends on POSIX threads because
707 the number of global structures is limited. NMEM no longer re-uses blocks
708 between threads ; it simply free's memory immediately but allocates in
709 "large" chunks as usual. We don't expect any performance penalties
710 because of this. The yaz_log system is still using a global log_level so
711 caution must be taken when modifying it with yaz_log_init_.. +
712 yaz_log_mask_str. This, however, should not cause any trouble because
713 these functions are called during initialization of application code
714 anyway. `yaz-config --libs server` returns libs for server applications;
715 `yaz-config --libs` returns libs for non-server applications.
717 New OID database - with public definitions in oid_db.h. Removed old OID
718 database including the head oid.h and definitions such as enum oid_value
719 and struct oident. The new OID database uses the same string names as
720 before but the 'protocol' is gone. There are now only two representations
721 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
722 converts from string to OID; functions with prefix yaz_oid_to_string
723 converts the other way.
725 Change to emit_term() in CQL-to-PQF query translation: when a term has
726 the /regexp relation modifier, do not process it for leading and
727 trailing "^" and "*", which have quite different meanings in regular
730 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
731 write handlers no longer carries a 'last' parameter. This will make
732 yaz_iconv flush "less" characters. A flush is performed by call to
733 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
735 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
736 removed, because function yaz_query_to_wrbuf does the same.
738 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
739 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
741 Deprecated MARC utility functions removed.
743 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
746 Branch split: YAZ_2_1_55_branch
748 --- 2.1.54 2007/03/16
750 Fix to ZOOM-C so that transparent reconnection is properly handled on
751 connections that are in asynchronous mode.
753 Fixed compilation on OpenBSD 4.0.
755 Large strings in GRS-1 records are now properly displayed in yaz-client.
757 Added character conversion support for "advancegreek"; based on patch from
760 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
761 sequence is met. Before the error was not set so it would be unknown.
763 Adjust yaz-marcdump MARC reader so that it skips until record separator
766 --- 2.1.52 2007/03/07
768 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
769 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
770 fd_set structure used as a bitmask for the FDs to be selected on.
772 Using ACX_PTHREAD macro to check for POSIX threads.
774 Fixed have-vsnprintf check.
776 --- 2.1.50 2007/02/23
778 Fixes for configure on BSD. Bug #900.
780 Added snprintf/vsnprintf wrappers for systems that don't have
781 limits (heavens forbid).
783 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
784 created before all previous tasks were completed and removed from the
785 task queue, the new task could be removed by a mistake.
787 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
789 Implemented pass-through CQL-to-PQF conversions. Bug #861.
791 Fixed bug #832: Problem with MARC/charset in yaz-client.
793 Fixed bug #668: save command line history for yaz-client.
795 Fixed bug #830: pkg-config support.
797 --- 2.1.48 2007/01/23
799 Extended ZOOM result set options with two options that may be read by
800 a client: resultSetStatus and presentStatus with values as specified for
802 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
804 Fixed bug #827: Using SSL fails on Debian etch.
806 Fixed bug #826: Weird looking chars for set of MARC records.
808 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
809 that is treated as an ItemOrder with itemRequest being an XML document
810 external. The value of "doc" is the content.
812 Extended the GFS search facility. New member of bend_search_rr
813 'estimated_hit_count' signals that hits is known to be an estmate
814 (higher or lower than real hit count). New member 'partial_resultset'
815 signals that the search was partial (hit count is lower or equal than
816 real hit count). For Z39.50, the information is stored in resultSetStatus
817 member of SearchResponse APDU. For SRU, the information is signalled
818 via SRU diagnostic 59: "Result set created with valid partial results
821 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
823 --- 2.1.46 2007/01/13
825 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
827 Added ZOOM_connection_peek_event.
829 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
830 the following new functions:
831 ZOOM_event_nonblock, ZOOM_connection_process,
832 ZOOM_connection_get_{socket,mask,timeout},
833 ZOOM_connection_fire_event_{timeout,socket}.
834 The existing blocking event handler, ZOOM_event, is a wrapper for the
835 + blocking ZOOM_event_sys_{poll,select}.
837 Implemented function ccl_xml_config which parses XML version of CCL
838 configuration (bug #798).
840 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
842 Added timings utility (yaz/timing.h)
844 --- 2.1.44 2007/01/03
846 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
849 Fixed bug #779: Rotation of apdu.log fails.
851 Fixed for character set conversions:
852 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
853 Honor G1 set in MARC-8 decoding.
855 --- 2.1.42 2006/12/17
857 Fixed bug #775: char conversion does not handle Alternative UTF-8
860 Implemented function yaz_marc_read_line which parses MARC line format
861 records. There is a wealth of formats out there. So far, this function
862 reads line records produced by yaz_marc_write_line.
864 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
865 more generic and easier to remember(!) options: -i format and -o format
866 which specifies input format and output format respectively - where
867 format is one of "marc", "marcxml", "line", "marcxchange".
869 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
870 does not print anything except warnings for records.
872 For yaz-marcdump, added support for MARC split into files (-s) with a given
875 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
876 spec, at http://www.loc.gov/standards/sru/record-update/
877 This has changed the binary layout of the following structs:
878 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
879 bend_update_rr . Patch by Ko van der Sloot.
881 Added GFS utility function bend_assoc_is_alive which returns 1 if
882 association is still alive (client is connected); 0 otherwise (client
883 closed connection). This allows busy servers to stop working for
886 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
887 been a separate piece of software. This version of ziffy has been modified
888 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
890 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
892 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
893 Client code may now interrogate options such as "init_opt_sort" to
894 find out whether the server claims to support various options.
896 --- 2.1.40 2006/11/27
898 Added utilities yaz_{set,get}_esn to set/get element set name from
901 Removed the build of libyazthread.la. The libyaz.so is the threaded version
902 of YAZ and has been so since YAZ 2.1.10.
904 Implemented ZOOM_record_error which returns error information for
905 record (surrogate diagnostic).
907 --- 2.1.38 2006/10/31
909 Updates for SRU Update by Ko van der Sloot:
910 1. Changed name from "operation" to "action"
911 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
912 versions in the code, marked as 'backward compatible'.
913 3. Added diagnostics for SRU Update.
915 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
917 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
919 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
921 For GFS, fixed problem with SRU diagnostic 'First record position out of
922 range' being issued for 0 hits.
924 zoomtst10 part of Windows Build.
926 --- 2.1.36 2006/10/13
928 Implemented yaz_filepath_comp which splits a path into file path
929 components (required by Zebra 2.0.3+).
931 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
932 BSD inspired license until now so this should not have any real impact on
933 anybody. See http://www.opensource.org/licenses/bsd-license.php
935 Fixed bug #687: Missing log lines.
937 Fixed bug #678: CQL to PQF translation does not preserve double-quote
940 Fixed bug #689: SRU diagnostics to be added.
942 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
943 whether a connection is idle (no more work do do).
945 --- 2.1.34 2006/10/04
947 Change type of optval from long to int for invocation of setsockopt with
948 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
950 Added support for specifying the max log file size for the Generic
951 Frontend Server. The size is given with option -r.
953 --- 2.1.32 2006/09/21
955 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
957 --- 2.1.30 2006/09/17
959 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
962 Fixed bug in Generic Frontend Server that could cause a server to stop
963 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
965 For the generic frontend server, the maximum record size is used as maximum
966 size of incoming packages (SRU + Z39.50). The value until was previously
967 only used in Z39.50 Init negotiation and, later, in a session controlled
968 sizes of records returned. This is controlled using -k option. It can be
969 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
971 --- 2.1.28 2006/09/04
973 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
976 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
978 New option for yaz-marcdump -lpos=value which allows setting a portion
979 of MARC header to a certain value.
981 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
983 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
984 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
986 --- 2.1.26 2006/08/15
988 Fixed problem with SRU mode type (soap, get, post) for yaz-client
991 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
993 --- 2.1.24 2006/08/08
995 Fixed MARC ISO2709 encoding routines to deal with character set
998 Minor changes to GFS logging. Database included in search request log
1001 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1002 cached/multiple records.
1004 Shared libraries are built by default on Unix+configure.
1006 Changed cql2pqf transformation to use a different evaluation order. The
1007 new order is: always, relation, structure, position, truncation, index
1008 and relationModifier. Old order was: always, relation, relationModifier,
1009 structure, index, position, truncation. Note that the the latter ones
1010 override former ones for identical attributes.. The new scheme means that
1011 it is possible to override any existing attribute with a relationModifier.
1012 And also that it is possible to override everything for the index rule
1013 (except the ones listed in relationModifier). No order is perfect but this
1014 one, we believe, covers more real cases.. The "always" should have been
1015 called "default", since the attributes there can be overridden with all
1018 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1019 compilation phase, but also for yaz-config --cflags output. This allows
1020 us to have public headers with Libxml2 stuff in them . It should also,
1021 eventually, make Libxml2 checks redundant in packages using YAZ, such
1024 --- 2.1.22 2006/06/15
1026 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1027 stored in uri, message and details.. Previously diagnostics were stored
1028 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1029 compatibility.. but he's probably the only one affected, so.
1031 Added support for CCL, compiled on the client side, in ZOOM-C. This
1032 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1033 input; the resulting query objects can be used for for searching with
1034 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1036 YAZ' configure searches for OpenSSL by default.
1038 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1039 SL_CTX_use_certificate_file. See
1040 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1041 for more info. Thanks to Ko van der Sloot.
1043 --- 2.1.20 2006/06/02
1045 Bug #600: SRU GET, POST support for yaz-client. Introduced
1046 command 'sru' which selects method SOAP/GET/POST.
1048 Allow missingValueAction to be specified for the sortspec string -
1049 function yaz_sort_spec. By default, the missing value action is null.
1050 Use ! to specify "abort". Use = followed by stringvalue to specify default
1053 Ensured that Present-handler (if defined) is called in GFS before any call to
1054 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1055 searchRetrieve requests.
1057 Documentation for YAZ is now based on the Docbook XML/XSLT using
1058 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1059 is no longer depending on jade/openjade or docbook-to-man scripts.
1060 PDF is no longer part of the distribution - but can optionally be
1061 made using DSSSL/jadetex or FOP.
1063 Added retrieval handling support in Generic Frontend Server to support
1064 conversion between MARC/XML as well as XSLTtransforms. See
1065 etc/yazgfs.xml for an example.
1067 Added Authentication support to Generic Frontend Server in SRU
1068 mode. Authentication using HTTP Basic is supported, as is the use
1069 of 'x-username' and 'x-password' parameters in the request itself.
1071 Added support for a new character set MARC8s identical to MARC8 except
1072 that it converts combined characters to single Unicode characters in the
1073 Latin-1 range (when possible).
1075 --- 2.1.18 2006/04/24
1077 ASN.1 compiler 0.4: generates brief Doxygen file header for
1078 generated .h/.c files.
1080 Utility yaz_iconv now supports conversion to MARC-8.
1082 New facilities for the MARC module. The reading - and writing of
1083 content are separate methods for the yaz_marc_t handle. The following
1084 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1085 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1086 format). Write functions have prefix yaz_marc_write_.. The existing
1087 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1088 available. Removed support for OAI-MARC and simplexml (not the
1089 simplexml from PHP5).
1091 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1092 to be returned for this connection.
1094 --- 2.1.16 2006/03/31
1096 Allow multiple languages and charsets to be specified with
1097 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1098 negcharset iso-8859-1,utf-8
1100 Translation of proximity nodes from CQL into PQF now works.
1102 Moved to automake 1.8, 1.9.
1104 Added function yaz_log_set_handler which allows a log handler to be
1105 installed. This handler will be called for all log messages. Output
1106 to file is also produced; but that can be disabled by passing NULL
1107 fname to yaz_log_init_file.
1109 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1111 For SRW (including GFS), accept application/soap+xml as content-type
1114 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1115 produces NO stylesheet reference even if a default stylesheet is specified
1118 --- 2.1.14 2006/03/14
1120 Updated Windows package to include yazd.dll + yazd.lib for the
1121 Development component.
1123 If the environment variable YAZ_LOG is set, then it is used as a
1124 string indicating the default level of logging to use if not
1125 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1126 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1127 used as before. So, for example, to omit warnings from YAZ logging,
1128 export YAZ_LOG=-warn
1130 cql_transform() now map structure and other attributes before indexes,
1131 so that index-specific structures and other attributes can override
1132 defaults. So now a combination of mapping specifications such as:
1134 index.dc.date = 1=date-modified 4=5
1135 does the right thing.
1137 cql_transform() now also respects the "always" mapping specification,
1138 which establishes an initial set of attributes to be used for all
1139 terms except where overridden by more specific attributes associated
1140 with the index, relation or modifier.
1142 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1143 which mode to use; one of "post", "get" or "soap" (SRW, default).
1145 Fixes for yaz_iconv routines: changed trie-based character set conversions
1146 to use only non-negative values for bit fields due to Sun's C compiler not
1147 supporting negative values.
1149 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1150 sequences where not read correctly. Fix by Rustam Usmanov.
1152 Updated win/makefile to use options, settings which makes things
1153 compile with VS C 2005.
1155 --- 2.1.12 2006/02/01
1157 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1159 In ZOOM socket code, use select instead of poll on MacOSX.
1161 ZOOM-C now support client-side compilation of CQL into RPN that is
1162 sent to the server, enabling CQL to be used against all Z39.50
1163 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1164 ZOOM_query object, and submit it using ZOOM_connection_search().
1165 The CQL-to-RPN translation uses a configuration file, the name of
1166 which must be specified in the Connection's "cqlfile" option.
1168 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1169 function, which takes as its start-term parameter a ZOOM_query object
1170 (which may have had either CQL or RPN set into it).
1173 --- 2.1.10 2005/11/29
1175 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1176 GFS to support this as well. Backend handler, bend_srw_update, does the
1177 update work. Code contributed by Ko van der Sloot.
1179 Allow retrieval of Search Result-1 information in ZOOM by the use of
1180 options that are attached to a result set. ZOOM documentation updated
1183 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1184 UTF-8 conversion. Patch by Raj Patel.
1186 Added option -m to GFS to control formatting of timestamps in log file.
1188 Added 'exit' as synonym for 'quit' in yaz-client
1190 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1191 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1192 for the new members. Patch by Ko van der Sloot.
1194 Added support for SRU POST. It is supported for content-type
1195 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1197 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1198 Instead make the library libyaz.la multi-threaded. Threading as a whole
1199 can still be disabled by configure option --disable-threads. Previosly,
1200 with older GLIBCs there were problems with MT libs under Apache. This
1201 has now been fixed a long time ago.
1203 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1206 CQL module modified to be case insensitive for relations/indexes/operations.
1208 Fixed bug in CQL transform code: incorrect value relationModifieder
1211 Added 'show all' command for yaz-client which retrieves all results
1214 Added new yaz-client, xmles, which takes a (private) OID and
1215 a document to be sent as an extended service request.
1217 Describe new yaz-client commands wait_response and set_auto_wait.
1219 Increase TCP/IP listener backlog from 3 (which I am guessing was
1220 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1221 that the socket will queue as many incoming connections as it's able
1222 to handle ongoing connections. In other words, it will never now
1223 refuse a connection that it would be able to handle merely because
1224 it's not got around to accepting() enough of the pending connections
1225 yet. This is the behaviour anyway under Linux, where the listen()
1226 argument is ignored; but not under BSD and on systems such as
1227 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1228 YAZ-based servers should now be uniform across operating systems in
1231 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1232 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1233 This allows yaz-marcdump to read large MARC batches (>2 GB).
1235 Modified all YAZ source files - except the source which is auto-generated
1236 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1239 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1240 corresponding to the existing *_setl() function. These allow option
1241 values containing arbitrary valuues.
1243 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1244 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1245 except that it returns an indicator of whether or not the sort
1246 criterion was accepted (0 for OK, -1 for invalid).
1248 --- 2.1.8 2005/06/07
1250 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1251 MARC output rather than returning "new" buffer.
1253 yaz-client warns about unknown init options.
1255 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1257 --- 2.1.6 2005/05/24
1259 Added support for SRW sort in Generic Frontend Server. Patch
1260 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1261 sortKeys - or NULL if none is provided.
1263 Fixed bug #307: It was impossible to specify indefinite/no timeout
1264 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1267 Added support for multiple languages and charsets to be specified in
1268 ZOOM. Each charset/language is separated by a blank. If negotiation is
1269 in effect in init-response, Option
1270 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1271 Code based on patch by Vasiliy Osadchuk.
1273 Fixed bug #306: infinite recursion that occurred when calling
1274 yaz_log_level_init as the first call (before other log level or
1277 Fixed bug in scan handling in front end server: if preferred-Position-In-
1278 Response was non-present, a NULL pointer referece was performed.
1280 --- 2.1.4 2005/04/26
1282 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1283 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1284 now defined for all those error codes. So instead of putting 109 in
1285 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1286 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1288 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1291 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1293 Program yaz-client now exits and produces an error message if multiple
1294 Z39.50 servers are specified on the command line (none or one allowed
1297 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1300 --- 2.1.2 2005/03/16
1302 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1304 Fixed bug #272: Preserve spacing for CCL terms.
1306 --- 2.1.0 2005/03/14
1308 Added support for virtual hosts and multiple backend servers for
1309 the YAZ frontend server. The configution is XML based and
1310 support specificition of CQL to RPN mappings and explain information.
1311 See section "Virtual Hosts" in the YAZ manual.
1313 Extended OPAC display utility. OPAC display utility renders
1314 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1315 to supplement yaz_marc_decode_wrbuf.
1317 Fixed a bug in MARC decoder that could caused it to crash for some
1318 invalid MARC records. More diagnostics and warnings where added in
1319 XML output (warnings, etc are stored in comments).
1321 --- 2.0.34 2005/02/08
1323 Fixes for UNIX domain sockets. Bug #261.
1325 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1327 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1328 Added yaz_marc_subfield_str which defines subfield lead string which is
1329 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1330 yaz_marc_endline_str which defines end of fields string used in
1331 YAZ_MARC_LINE format. Default string is newline.
1333 Experimental support for MarcXChange. This format can be produced
1334 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1335 http://www.bs.dk/standards/MarcXchange.xsd
1337 Added yaz-client commands scansize that sets maximum number of
1338 entries to be returned by scan.
1340 --- 2.0.32 2005/01/11
1342 Added support for SRW scan in yaz-client and Generic Frontend Server.
1344 * Added whereInList member to SRW Scan Term.
1346 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1348 Fixed NMEM system to return aligned blocks on the smallest boundaries
1349 that are suitably aligned for all possible types on the particular
1350 architecture YAZ is being built for.
1352 --- 2.0.30 2005/01/04
1354 Fixed numerious warnings that was issued with newer versions of GCC.
1356 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1357 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1360 Make YAZ Generic Frontend Server slightly faster.
1362 Enhance (and reduce) logging for Generic Frontend Server.
1364 Revert YAZ log system so that it flushes every write operation
1365 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1367 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1368 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1369 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1370 will effectively disable old definitions.
1372 --- 2.0.28 2004/11/09
1374 Added yaz_log_time_format which specifies log format using
1377 Added yaz_log_module_level which returns mask for a module. Value
1378 is non-zero mask a if module is enabled; zero if disabled.
1380 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1381 in include/yaz/cql.h.
1383 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1385 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1387 Fixed bug #172: RPM builds does not enable SSL.
1389 Doxyfile.in part of dist. Doxyfile generated by configure.
1391 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1392 are given and the corresponding component does not exist.
1394 Extend CCL documentation in YAZ reference. Describe r=r.
1396 --- 2.0.26 2004/10/01
1398 Fixed MARC->MARCXML conversion to properly deal with
1399 fields, subfields, indicators having non-ASCII characters.
1401 Fixed MARC->MARCXML conversion so that ASCII control characters
1402 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1405 Added YAZ GFS support for conversion from Z39.50 surrogate
1406 diagnostics to SRW surrogate diagnostics.
1408 Bug fix: YAZ GFS did not return schema in explainResponse.
1410 --- 2.0.25 2004/09/30
1412 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1413 now converts recordSchema to elementSetName as well as schema URI.
1415 Fixed bug in COMSTACK that prevented HTTP request packages from being
1418 --- 2.0.24 2004/09/29
1420 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1421 does not require white-space before and after the dash in a range, e.g.
1422 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1425 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1426 due to new GCC removing "redundant" code.
1428 Added yaz-client commands scanpos and scanstep that sets preferred
1429 position and step-size for scan.
1431 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1433 Added CCL utility ccl_qual_buf which parses one or more CCL
1434 spec lines in a buffer.
1436 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1437 of name and value - ignoring empty lines and comments.
1439 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1441 Added odr_get_element_path which returns current element path for an
1442 ODR handle. This utility is useful in error handling or user-defined
1445 Added ODR_PRINT utility odr_set_stream which is is a more generic
1446 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1447 to a write function and pointer to close function. The close function - if
1448 non-NULL - will be called during odr_destroy.
1450 Fixed bug in CCL parser where truncation char was not removed from
1451 right side when truncation=both was in effect.
1453 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1456 --- 2.0.23 2004/08/11
1458 Fix buffer overrun in CQL parser when dealing with proximity (%).
1460 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1461 to UTF-8/UCS conversion is now only based on codetables.xml.
1463 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1465 --- 2.0.22 2004/08/06
1467 Add support for more "commit changes" in ZOOM (uses Extended Services).
1469 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1472 Yet another small fix for configure of SSL.
1474 --- 2.0.21 2004/05/14
1476 Fix SSL libs for configure when --with-openssl=DIR is given.
1478 --- 2.0.20 2004/05/10
1480 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1482 SSL comstack now uses yaz.pem certificate file on server side
1483 by default. Certificate filename can be configured by calling
1484 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1486 Fix bug regarding multiple calls to ZOOM_connection_connect.
1488 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1490 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1491 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1493 ZOOM now allows inspection of X509 peer certificate for verification.
1494 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1496 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1497 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1498 as "modular" but it simplifies things.
1500 Added cs_get_peer_certificate to that returns peer X509 PEM.
1502 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1503 NULL if SSL is unavailable.
1505 Documentation about MARC decoding tools.
1507 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1509 --- 2.0.19 2004/03/30
1511 Rename CHANGELOG to NEWS to follow GNU style packing.
1513 Fix bug with missing initialization of member in init_diagnostics.
1514 This bug affects threaded version of GFS server.
1516 --- 2.0.18 2004/03/20
1518 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1521 Ensure zlib.dll is packed with Windows install.
1523 --- 2.0.17 2004/03/17
1525 Fix encoding of xsd:string to use text instead of CDATA.
1527 Fix endless loop in CQL parser with unbalanced ".
1529 Use a more compact way to store MARC-8 conversion tables.
1531 --- 2.0.16 2004/03/16 Debian only
1533 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1536 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1541 --- 2.0.15 2004/03/01
1543 Another fix for decoding of XML packed records.
1545 --- 2.0.14 2004/02/25
1547 Fixes for Chunked encoding. White space not ignored after length spec.
1549 Update NS and use default NS for SRW diagnostic elements.
1551 --- 2.0.13 2004/02/23
1553 Implement ZOOM_resultset_cache_reset which resets record cache.
1555 Implement ZOOM_resultset_sort which sorts a result set.
1557 Implement chunked HTTP transfer.
1559 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1561 --- 2.0.12 2004/02/16
1563 Added member 'schema' to bend_explain_rr structure so that backend
1564 can specify explain record identifier. Defaults to Zeerex 2.0.
1566 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1568 --- 2.0.11 2004/02/16
1570 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1573 Added init command for yaz-client which sends "extra" init request.
1575 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1576 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1578 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1580 Make ZOOM error code for "invalid query".
1582 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1584 --- 2.0.10 2004/02/05
1586 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1589 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1591 Added option -p <file> to make Generic Frontend Server to write PID file.
1593 Added option -D to put Generic Frontend Server in background on its own.
1595 Make ZOOM C recognize option "password". If unset, "pass" is used
1596 (for backwards compatibility).
1598 Fixed a bug in Generic Frontend Server that could make it crash if a
1599 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1602 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1603 Must be issued before open, in order to be in effect.
1605 --- 2.0.9-6 2004/01/12 Debian/Windows
1607 Make the SRU server more picky WRT unknown params, etc.
1609 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1611 New YAZ client command, options, that sets Z39.50 options.
1613 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1614 options from a string of tokens (one token for each option bit).
1616 Update SRW diagnostic code messages.
1618 --- 2.0.9-5 2004/01/07 Debian/Windows
1620 Handle user defined stylesheet for SRW/SRU.
1622 --- 2.0.9-4 2004/01/06 Debian/Windows
1624 Fix bug in decoding of Content-Length.
1626 --- 2.0.9-3 2004/01/06 Debian/Windows
1628 Fix a bug with decoding of XML packed records.
1630 --- 2.0.9-2 2004/01/05 Debian only
1632 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1634 Fix bug in SRW/SRU diagnostics decoding.
1636 --- 2.0.9 2004/01/05
1638 Fixed bug in Generic Frontend Server which could drop records exceeding
1639 preferred message size. Reported and fixed by Irina Dijour.
1641 Fixed calculation of package size for structured records in Generic
1642 Frontend Server. Reported and fixed by Irina Dijour.
1644 Fixed namespace for SRW/SRU diagnostics.
1646 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1648 --- 2.0.8 2003/12/22
1650 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1651 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1654 CQL changes to reflect recent changes to the specification:
1655 * Documentation talks about context sets instead of index sets.
1656 * Documentation talks about indexes instead of qualifiers.
1657 * The CQL-to-PQF transformer's configuration file now uses
1658 "index.set.name = <attributes>" instead of the old form
1659 "qualifier.set.name = <attributes>". (Both forms are still
1660 understood but the latter is deprecated.)
1661 * CQL terms with no explicit index specified are now interpreted as
1662 cql.serverChoice instead of srw.serverChoice (which of course
1663 behaves exactly the same.)
1665 --- 2.0.7 2003/12/16
1667 MARC conversion can now generate ISO2709 output in another
1668 character set. yaz-marcdump uses this facility if you invoke it
1671 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1672 functions from there can be used from C++.
1674 --- 2.0.6 2003/12/04
1676 Frontend server now transfers memory from decoded packages to stream
1679 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1680 references to show up.
1682 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1683 the ZOOM Abstract API. The older names for the same options are still
1684 also supported for the benefit of old applications.
1686 ZOOM-C supports "implementationId" and "implementationVersion" options
1687 to go along with "implementationName". These allow the user code to
1688 specify identification strings to be sent to servers.
1689 Add OID for the new ExtLite attribute set.
1691 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1692 as requested/supplid by Ere Maijala <ere@atp.fi>
1694 For generic frontend server, reverse the order of
1695 "toolkit-supplied / application-supplied" strings sent as implementationId,
1696 Name and Version. Also, remove the spaces around the slash. This brings
1697 the GFS in line with the behaviour of ZOOM-C on the client side.
1699 Add function ZOOM_scanset_display_term.
1701 yaz-client shows scan displayTerm if present.
1703 Utility yaz-iconv is now installed by default along with the man page
1706 Extend configure check for OpenSSL to use pkg-config where available (such
1709 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1710 server to specify uid/gid/mask for socket using the format
1711 unix:[user=uid,][group=gid,][umask=mask,]file=path
1712 If file= is omitted the existing format is assumed, e.g.
1714 in which case the mask is 0666 (rw for everybody).
1716 Major restructure of YAZ source. All source in libyaz is in src directory.
1717 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1718 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1720 Added man page for utility yaz-marcdump (used to be called marcdump).
1721 yaz-marcdump is installed by 'make install'.
1723 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1724 of incoming package failed.
1726 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1728 Change prototype of odr_perror: add const to message string.
1730 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1732 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1733 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1734 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1735 DNS lookup. There should not be any compatibility problems with this
1736 assuming that blocking=1 or 0 is used.
1738 Fix bad reference in UNIX comstack in function cs_addrstr.
1740 Fix for compilation on AIX.
1742 The generic front-end server (server/seshigh.c) now supports returning
1743 Init diagnostics to the client in User-information-field, in
1744 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1747 --- 2.0.4 2003/09/04
1749 Allow any CQL relation (not just all,any,exact,scr).
1751 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1752 that features the same UI.
1754 Implemented command update0 in YAZ client which is equivalent to
1755 update but uses old of Ext Update ASN.1.
1757 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1758 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1759 Previously no OID was used for this info.
1761 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1762 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1763 returns 'malformed search term' otherwise.
1765 SortResponse member resultCount now set to NULL in sort handler of
1768 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1771 Add three new utility functions for translating OIDs between various
1772 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1773 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1774 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1775 char *oid_to_dotstring(const int *oid, char *oidbuf);
1776 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1778 Reverted modifications for ES Update definition for z_IU0Update
1779 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1780 is back to YAZ 2.0.2.
1782 String value attributes for CCL parser.
1784 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1785 which their FirstSearch server returns in Init responses, sometimes
1786 carrying useful diagnostic information when Init fails. This has the
1787 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1788 "z39.50/oclcui.asn", where its definition is somewhat different from
1789 what OCLC document on their web-site, as required to interoperate with
1792 Support for anonymous authentication in yaz-client. Use the command
1795 * Fix the OID of the Index Data-local "admin" Extended Service from
1796 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1797 the 1000, which indicates a locally-defined OID, was a mistake.
1799 --- 2.0.3 2003/06/20
1801 Fix CCL directive @case handling so that it affects string match for
1802 both CCL keywords and qualifiers.
1804 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1805 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1806 Decoder has been updated with ASN.1 changes as listed in
1807 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1808 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1809 z_IUUpdate, remains unchanged.
1811 ZOOM_record_get may now return a record in a specific character set.
1812 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1813 "from" is the character set of record as returned by target. "to" is
1814 the character set to be returned. If omitted, "to" is UTF-8.
1816 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1818 New ODR utility, odr_getelement, which returns name of element for
1819 which encoding/decoding failed.
1821 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1822 in cases where a required element was omitted.
1824 Bug fix: some MARC8 sequences were not converted.
1826 New ZOOM option "step" which specifies number of records to be
1827 retrieved in one chunk. Used in conjunction with "start" and "count".
1829 SRW support for yaz-client. Use scheme http: to use it, e.g.
1832 yaz-client no longer does (un)intelligent character set conversions
1833 by default. Can be enabled with charset and marc_charset commands.
1835 xmalloc trace fix for 64-bit systems such as DEC alpha.
1837 Solaris 2.6 compile fix.
1839 New function, cql_strerror() translates SRW error codes, as returned
1840 by cql_transform_error(), into human-readable English strings. Used
1841 in yaz-client diagnostics when appropriate.
1843 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1844 converts it into a type-1 query which is sent to the server. This
1845 makes CQL available for use with all Z-servers, as opposed to the tiny
1846 minority that can handle CQL queries themselves.
1848 --- 2.0.2 2003/04/28
1850 New Debian package layout similar to the Redhat Package layout.
1852 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1853 and search result respectively.
1855 --- 2.0.1 2003/04/25
1857 Redhat package is now several packages: libyaz (runtime libraries),
1858 libyaz-devel (development and documentation, and yaz (utility programs).
1859 Package spec file by Morten Bogeskov.
1861 New member 'schema' in struct bend_fetch_rr which the name of requested
1862 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1863 handler MAY set this to reflect the schema of the returned record.
1865 New member 'display_term' in struct scan_entry. GFS now sets member entries
1866 and allocates scan entries to be filled by user scan handler. In previous
1867 version, entries member was allocated by the scan handler. That still works,
1868 but the GFS will ignore member display_term - assuming it was NOT set by
1869 the handler. The fact that the GFS now allocates the entries both allows
1870 for new members and makes a scan handler easier to write.
1872 Fix CQL lex buffer overflow.
1874 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1875 SRU default recordPacking is string.
1877 SRU protocol support for frontend server.
1879 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1881 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1883 Added scan for the ZOOM shell (zoomsh).
1887 * String Identifers for Schemas (Amendment 5).
1888 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1889 Old definition for schema
1890 Odr_oid *schema; /* OPT */
1895 Z_InternationalString *uri;
1896 #define Z_Schema_oid 1
1897 #define Z_Schema_uri 2
1900 * resultCount parameter to Sort Response (Amendment 1).
1901 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1903 Support for SRW 1.0 over HTTP. This is an optional feature and
1904 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1907 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1908 on the same port. SRW SearchRetrieveRequests are mapped
1909 to bend_init,bend_search,bend_fetch,bend_close.
1911 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1913 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1914 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1916 ZOOM connections are SRW based if schem http is used for hostname
1917 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1918 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1920 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1921 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1922 distance=n, order=true/false, relation=le, prox unit=word. If
1923 n is omitted, distance 1 is used.
1925 Fixed problem with C compiler include path in wrong order.
1927 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1928 on Solaris. Patch from Ko van der Sloot.
1930 New MARC decode API. All new functions operate on a yaz_marc_t
1931 handle. The most important new functions are: yaz_marc_create,
1932 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1933 decode and destroy respectively. Decoder can produce formats
1934 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1935 include/yaz/marcdisp.h.
1937 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1938 to UTF-8, UCS-32, wchar_t or Latin-1.
1940 * Prototypes for yaz_iconv_-functions moved to separate header
1941 include/yaz/yaz-iconv.h.
1943 Make a few private functions 'static' in unix.c. This prevents
1944 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1946 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1947 are set when Init Response is received.
1949 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1950 but returns diagnostic set as well.
1952 New function yaz_strerror which is a portable wrapper for
1953 strerror/strerror_r/GetLastMessage.
1955 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1956 is returned for MARC. If type is "oai", then OAI MARC is returned.
1958 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1961 --- 1.9.2 2002/11/26
1963 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1965 Fix bad race conditions on SIGTERM and terminate gracefully in
1968 Move retrieval (data1) module to Zebra since nobody seems to be
1971 Add GRS-1 render for ZOOM using same format as yaz-client.
1973 --- 1.9.1 2002/10/05
1975 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1977 Fix broken ESpec handling in data1 module.
1979 SGML reader parses comments and makes them part of the data1 tree.
1981 Added several type casts so that YAZ compiles as C++ code.
1983 ZOOM didn't handle PDU encoding failures properly.
1985 Added more Bib-1 diagnostics (approved extensions).
1987 GNU configure: better check for iconv.
1989 More portable use of accept, getpeername. Check for socklen_t. Use
1990 int/size_t if socklen_t is not defined.
1994 PQF parser rejects bad queries - including those with extra
1995 characters in them. PQF parser used to silently ignore that.
1996 Cleaner API for PQF added, which allows you to get detailed
1997 error information for bad queries (see yaz/pquery.h).
1999 Fixed bug in ZOOM_record_get for type "database".
2001 Implemented mini iconv library supporting conversions between
2002 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2004 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2006 --- 1.8.9 2002/08/20
2008 Fixed ZOOM C record cache so that preferredRecordSyntax and
2009 elementSetName is used to check for already fetched records.
2011 --- 1.8.8 2002/08/02
2013 Added three members in bend_initrequest structure to facilitate
2014 character set negotiation.
2016 Fixed a bug in frontend server that could cause indefinite
2017 loops under rare conditions.
2019 Revised character set utilities (charneg.h) so that encoding
2020 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2022 For PQF, directive @term <type> sets term type for Scan/Search.
2023 Here <type> is general, string, numeric, null. The term type
2024 is inherited - just like @attr.
2026 New call odr_set_charset that sets character set conversion for
2027 international-strings on a ODR stream. Prototype is:
2028 int odr_set_charset(ODR o, const char *to, const char *from);
2029 The InternationalString is still represented as C string in YAZ
2030 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2031 won't). On the protocol level, you can use any encoding.
2033 Support for UNIX sockets in ZOOM.
2035 Solaris recv sometimes returns errno == ENOENT. It is treated as
2036 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2038 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2039 both client and server. Code by Morten Bogeskov.
2041 --- 1.8.7 2002/05/22
2043 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2044 that they can be used directly from Visual Basic. You must recompile
2045 your windows APP if you're using ZOOM.
2047 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2048 Commands "lang" and "charset" sets language and character set respectively.
2049 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2050 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2052 Attributes from multiple CCL fields may be OR'ed rather than merged
2053 using directive "@field or". Fields are still merged by default -
2054 equivalent to "@field merge".
2056 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2059 Fixed bug in zget for parameter ExtendedServicesResponse.
2063 --- 1.8.6 2002/03/25
2065 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2067 Client displays USR.1:SearchResult-1 (hits per term).
2069 Additional Search Info for search in Generic Frontend Server.
2071 Fixed CCL parsing of "field=s".
2073 WIN32 installer - using the excellent NSIS software from nullsoft.
2075 Fixed CCL parsing of "field = - <number>".
2077 Added function yaz_marc_decode that decodes MARC for line mode
2078 display or XML (similar to that used by JZKit).
2080 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2081 Z39.50. But ISO/ILL was, however.
2083 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2084 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2086 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2087 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2089 --- 1.8.5 2002/02/03
2091 New YAZ client features: Command completion and new commands:
2092 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2093 Code provided by Jacob Poulsen.
2095 New call oid_trav, that visits all registered OIDs via callback.
2097 Function ZOOM_record_get now returns const char pointer rather than
2098 void pointer. It saves a lot of type casts.
2100 For YAZ client, command "auth" now allows you to set authentication
2101 in IdPass style. It is enabled when three tokens are given - order
2102 is user, group and password.
2104 Fix memory leaks in MARC record handling for ZOOM.
2106 New option for YAZ client, -k <kilobytes> that sets
2107 maximum record size. Similar to -k option for generic frontend
2108 server and yaz-ztest.
2110 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2112 Prefix query parser reports "fail" when bad attribute set is given.
2114 Fix in MARC decoder. Proximity logging. Fix for attribute set
2115 in scan handler for server. Patches by Shigeru Ishida.
2117 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2120 Configure option --with-openssl=<dir> now works when a directory is
2121 specified. Patch provided by Morten Bogeskov.
2123 New option for YAZ client, -u <auth>, that sets authentication.
2125 ZOOM fix: error information was sometimes "missing", since error
2126 was cleared/reset too when it shouldn't.
2128 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2130 --- 1.8.4 2002/01/04
2132 Scan for ZOOM API. New object ZOOM_scanset. New functions
2133 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2134 ZOOM_scanset_destroy.
2136 New ZOOM function, ZOOM_connection_last_event, that returns type
2137 of last event (such as "receive data", "send data", "apdu received",
2140 New ZOOM option, schema, that specifies schema for retrieval.
2142 New CCL feature. Qualifiers can be aliases for one or more
2143 other qualifiers (if more than one is given, OR is used).
2145 ZOOM uses named result sets if target supports it.
2147 Two new YAZ client commands: . (dot, which sources a script of YAZ
2148 client commands), and ! (to execute shell command.). Implemented
2151 Working on Debian packages.
2153 --- 1.8.3 2001/11/19
2155 YAZ client enables named result sets only if target supports it.
2157 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2159 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2160 with key="host" to get same result.
2162 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2163 Function Z3950_resultset_record(s) returns references to records
2164 "owned" by resultset. To become owner use Z3950_record_clone.
2166 Function z_ext_record handles Extended Services. Thanks to
2169 --- 1.8.2 2001/11/12
2171 CCL Parser fix: ignore token comma when dealing with and-lists.
2173 Documentation updates for COMSTACK.
2175 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2176 Changed prototype Z3950_records. For some functions, int parameters
2177 were changed to size_t.
2179 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2182 New MARC decode/display function, marc_display_exl, which properly rejects
2183 non-ISO2709 records. YAZ client uses it.
2185 --- 1.8.1 2001/10/29
2187 Fix bug: local attribute set wasn't set correctly in PQF strings.
2191 * Old Z39.50 codecs no longer supported.
2193 Added ZOOM C binding. See http://zoom.z3950.org/
2195 Renamed states for COMSTACKs to avoid confusion with events.
2197 Implemented cs_look and proper cs_rcvconnect.
2199 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2201 Configure detects POSIX threads on OpenBSD.
2203 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2204 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2206 When error is returned from present handler, non-surrogate diagnostic
2207 is returned in present response (and fetch handler is no longer called).
2209 * Minor adjustments to pquery parser (PQF). Token characters may be
2210 escaped by using backslash (C-style).
2212 PQF parser allows string attribute values to be specified. For @attr,
2213 non-numeric characters after the equal-sign are treated as strings
2214 (e.g. @attr 9=title).
2216 CCL trunction character may be defined (@truncation in file)
2218 * function zget_ExtendedServicesRequest sets waitAction to
2219 waitIfPossible (was wait).
2221 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2224 CCL operator names may be set in field definition files (CCL_bibset).
2225 See ccl/bib1 for an example.
2227 Fixes in ASN.1 compiler for C++ compatibility.
2229 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2230 and "op_or" to avoid conflict with C++.
2232 Fixed problem with GNU readline detection on Redhat 7.0.
2234 Added step-size for Scan backend handler.
2236 Fixed bug that made the frontend server crash when no attribute
2237 set was specified for scan.
2239 Front-end server automatically switches to original working directory
2240 when installed as an NT service. Previously -w had to be specified to
2243 Added extended attributes for retrieval module (data1), so that data1
2244 records carry d1_readXML/SGML attributes. d1_read also supports
2245 null-data rules ( <tag/>)
2247 On UNIX when POSIX threads are available, a separate library libyazthread
2248 is created. Programmers should link with that library and the yaz library
2249 when using threads. The reason for the split was that some applications
2250 on Linux, such as Apache, doesn't work well when using shared objects that
2253 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2254 (or any frontend server) in SSL mode by specifying ssl: followed by
2255 address. Only tested on UNIX.
2257 Added feature for CCL module. Virtual structure s=al or s=ol generates
2258 and-list and or-list respectively instead of phrase search.
2262 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2263 log_mask_str. This was done to avoid name conflicts with other libraries
2264 (such as other PHP extensions).
2266 Added raw OID member for preferred record syntax (request_format_raw)
2267 and returned record syntax (output_format_raw) for backend fetch method.
2269 Config file yaz-config now accepts options so that it returns specific
2270 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2272 Shared library support for UNIX using GNU libtool.
2274 * Modified backend interface. Request/Response struct's replaced by
2275 one read/write C struct. For example bend_fetchrequest and
2276 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2277 Every handler - even search has to be registered in bend_init
2278 handler. This means that the YAZ library no longer refers to
2279 external functions and it makes it possible to make the whole
2280 thing a single DLL/SO.
2282 Added Segment handler for backend server.
2284 Added Zmbol/Zebra administrative functions to YAZ client.
2286 Threaded frontend server on UNIX (when POSIX Threads are available).
2287 Starting the server with option -T enables multi-threading.
2291 Added configure option --enable-comp/disable-comp to control use
2292 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2293 located in sub directory asn.
2295 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2296 in ${exec_prefix}/bin along with the other programs yaz-client and
2299 GNU automake used to maintain makefiles.
2301 Added several OID's.
2303 Changed retrieval module so that we can load records with no abstract
2304 syntax defined. Tagpaths in these records are fully composed of string
2307 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2311 On UNIX, the generated makefile now supports a proper 'make install'.
2312 The prefix can be set via GNU configure to set the install location
2313 (default is /usr/local).
2315 * YAZ programs client and ztest were renamed to yaz-client and
2316 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2317 locations, such as /usr/bin,/usr/local/bin,etc.
2319 * YAZ Header files were moved from include to include/yaz. YAZ Header
2320 files are referred to as include <yaz/log.h> rather than <log.h>.
2321 The YAZ include path (-I ..) is therefore the same as before. Programmers
2322 should update their #include statements or use -Ipath/include/yaz
2323 instead. The main motivation for doing this change is that YAZ header files
2324 can be installed in "standard" locations /usr/include,/usr/local/include
2325 without introducing conflicts, since ALL YAZ header files are stored
2326 in subdirectory yaz (under /usr/include for example).
2328 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2329 rather than project/workspace files. We switched because project files
2330 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2333 Changed name of logging function, logf, to yaz_log, to prevent name
2334 clash with some math-log functions. The YAZ header log.h defines logf
2335 to yaz_log (#define) so there should be no incompatibilities by this
2338 Added bend_start/bend_stop handlers for server. These handler are
2339 called on start/stop of server. For windows they are called whenever
2340 a service is started/stopped.
2342 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2343 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2344 in util/yc.tcl. The auto-generated C code structures are, in a few
2345 cases, incompatible with the old decoders. There are differences in the
2346 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2347 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2348 The preprocessor variable ASN_COMPILED is defined when the compiled
2349 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2350 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2351 wish to use the old encoders/decoders you can specify --disable-yc
2354 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2355 version so that it supports both new - and old version of DB Update
2357 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2358 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2359 change. The name parameter can be set to 0 in which no name is specified
2360 for the construction. The macros odr_implicit and odr_explicit sets name
2361 parameter to zero for the construction involved. New macros
2362 odr_implicit_tag and odr_explicit_tag are similar to the others,
2363 except that a name parameter is added. For programmers' that don't use
2364 ODR they probably only need to change the call to z_APDU and z_External.
2366 Added access control facility by interfacing the TCP wrapper library.
2367 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2368 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2369 name of the daemon and enables the access control as specified in
2370 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2372 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2373 den Dool <H.M.vdnDool@kub.nl>.
2375 Added reference ID parameter to most functions in server API - refer
2376 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2378 Changed name of ccl library to libccl.a (was ccl.a).
2380 Fixed bug in decoder for Explain (Category TargetInfo).
2382 Added support for GNU readline in client. Thanks to Jacob Poulsen
2383 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2385 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2386 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2387 IMPLEMENTATION! This change was made to the development version before
2388 the ZIG decided to retract the amendment. If any users MUST be
2389 compatible with the original Update definition, PLEASE CONTACT US, and
2390 we will include a separate definition corresponding to the old Update
2391 ES. Note that because of the change to the ASN.1 of the
2392 TaskPackageRecordStructure we cannot define a single structure that
2393 will support both versions.
2395 * Added const modifier to buffer parameter for some ODR/BER encoding
2396 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2397 completeWAIS, odr_dumpBER.
2399 Fixed bug in client.c which caused a crash when a scanResponse didn't
2400 contain positionOfTerm.
2402 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2403 * will cause an error in a client if a non-YAZ target sends both a
2404 * list of Scan entries and non-surrogate diagnostics.
2406 Retrieval module enhancements. Tag sets may be typed in the reference
2407 to it. From the .abs-file the "tagset" directive takes a third optional
2408 integer type for the tag set referenced. From a .tag-file the "include"
2409 directive takes a third optional type as well. The old "type" directive
2410 in the tag set itself is still recognized but acts as the default type
2413 Backend interface change. Individual Scan terms returned from bend_scan
2414 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2415 in include/backend.h.
2417 Retrieval module enhancements. Multiple tag sets and attribute sets may
2418 be specified in abstract syntax specs. Revised the error/warning for
2419 logging messages reported by the retrieval module when reading the
2422 Object Identifier system (oid_..) changed. The API is backwards
2423 compatible but the oid-routines now allocates new OID's when needed.
2424 Raw OID's may be specified in oid_getvalbyname.
2426 YAZ now uses GNU configure to generate Makefile(s).
2428 * Minor changes in some of the member names of DeleteResultSetRequest and
2429 DeleteResultSetResponse. See include/proto.h.
2431 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2432 and added member 'languages' in TargetInfo (which was missing).
2434 Changed the way attribute sets are handled in the retrieval
2435 module. These are now cached, just like the abstract syntaxes
2438 Changed YAZ so that it links with compiled ASN.1.
2440 Added Explain-schema definitions and mapping routines. The following
2441 Explain categories have been implemented: AttributeDetails,
2442 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2444 Fixed minor bug in Windows version of Server Library.
2446 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2448 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2450 Added EXTERNAL: UNIverse Resource Report (non-standard).
2452 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2453 ENUMERATED and SET OF.
2455 * Added 'const' to some of the char pointer arguments for the
2456 functions, data1_read_node, data1_getelementbytagname,
2457 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2460 Fixed bug in data1_insert_taggeddata - the last_child member of
2461 parent wasn't initialised.
2463 * Changed data1_read_record and data1_read_node so that the supplied
2464 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2465 doesn't refer to any parts of the "SGML"-buffer.
2467 Fixed bug in server library (Windows version of statserv_remove).
2469 * Changed code so that it compiles as C++. The type definition
2470 of Odr_fun which is a member of Odr_arm was changed. The result is,
2471 that an explicit typecast is needed for the fun pointer when
2472 using Odr_arm - as in:
2473 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2475 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2477 Implemented the new structured date and time definition as approved
2478 by the ZIG. Added schemaId element to the specificTag in Espec-1
2479 (also approved at the last ZIG). Thanks to RVDM.
2481 Added some Object identifiers (RVDM).
2483 Changed the Update Extended Service (RVDM).
2485 Added command "refid" to client which specifies referenceId for
2486 the following requests.
2488 Implemented extended service handling for server. See ztest.c
2489 for an example as well as backend.h. New handlers are registerd
2490 in the Init handler.
2492 * Changed interface for sort in server.
2494 Added new members to statserv_options_block. It allows a server
2495 to read options from another source than just the command line. Thanks
2496 to Charles Woodfield.
2498 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2499 renamed to zboolean. Some C++ compilers complained about the name.
2501 Minor changes to gils.abs. Added index 's' (sort) on title
2502 and date/time-last-modified.
2504 --- 1.4pl2 1998/1/30
2506 Fixed bug in server library regarding inetd mode (-i). This bug
2507 was introduced by release 1.4.
2509 --- 1.4pl1 1998/1/29
2511 Added sort facility in client and backend server interface.
2513 Fixed problem with dependencies in Makefile(s).
2515 Fixed bugs for encoders/decoders of extended services and
2518 Implemented sub-tree feature for schemas. Sub-trees are
2519 referenced in *.abs-files. See explain.abs for an example
2520 of the use of this feature.
2522 Modified bib1.att; local attributes for ANY didn't include
2523 ANY itself (only affects use of the retrieval module).
2525 Fixed bug in plain SGML reader in function data1_read_node:
2526 tags with prefix "var" was incorrectly interpreted as variants.
2528 Added feature "sub-schemas" to enable references to - and definitions
2529 of - group of elements.
2531 * Removed member parent from type data1_element (in data1.h).
2533 Implemented function odr_nullval() that returns the value of
2536 * Removed member num_children from data1_node (in data1.h).
2538 Made NT service interface part of the server library. The
2539 function statserv_main uses the NT service when required and
2540 calls the statserv_start / statserv_close routines.
2542 Routine zget_SearchRequest and zget_PresentRequest fills
2543 resultSetName/Id member with "default" instead of "Default".
2545 Fixed memory leak in server. Request queue member wasn't freed.
2547 Fixed nmem_exit so that memory is freed.
2551 Revised the CCL parser utility to be thread safe.
2553 Added function, oid_ent_to_oid, to replace the function
2554 oid_getoidbyent, which is not thread safe.
2556 * Added nmem_init and nmem_exit to initialize and release
2557 NMEM resources. Function nmem_init should be called once in the
2558 initial thread before NMEM/ODR is used. statserv.c and client.c
2559 have been changed accordingly. The change was necessary to make
2560 NMEM thread safe. The NMEM memory pool is shared amongst threads
2561 in a process. Unix-based applications will still work fine without
2564 Added NT Services interface for the the Z39.50 (statserv) Server.
2565 Refer to the ztest.c source on the usage.
2567 Windows 95/NT port using MSVC5.0. Project files are included in the
2570 * Defined new 'global' handle for the retrieval (data1) system. The
2571 new handled, data1_handle, describes the state of the data1 system.
2572 This handle is passed as first argument to virtually all
2573 data1 related routines. The functions data1_create and data1_destroy
2574 creates and destroys a data1 handle respectively.
2576 Added ODR encode stream member to all backend request structures
2577 init, search, scan etc. This stream should be used to allocate all
2578 memory used for the response when thread safe operation is needed.
2580 Changed the comstack utility, cs_addstr, to be thread safe. The
2581 returned hostname string returned by the function is now part the
2584 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2585 function. The cs_straddr takes a COMSTACK handle as argument, so this
2586 function must be used after cs_create and before bind/connect.
2587 This function is thread safe.
2589 Moved test server to 'ztest' directory - generic server code still
2590 in 'server' directory.
2592 Made prefix query (pquery.c) utility thread safe.
2594 Added new function modifier YAZ_EXPORT to 'export' public DLL
2595 functions when using windows (see include/yconfig.h).
2597 Added definitions to the OID database (util/oid.c) (RVDM).
2599 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2601 Added call to ccl_rpn_delete in client program.
2603 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2604 release of RPN structure.
2606 Added support for C++, headers uses extern "C" for public definitions.
2607 With input from RVDM.
2609 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2610 Thanks to Ronald van der Meer (RVDM).
2612 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2614 Added support for private extensions to the OID database
2615 (oid_setprivateoids()). Thanks to RVDM.
2617 Added optional, physical ANY (key replication)
2619 Fixed null-reference problem in GRS-1 output filter.
2621 Proximity operator added to Prefix Query Format (PQF).
2623 In test client command "base" accepts multiple databases.
2625 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2629 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2631 Smallish bug-fixes in the new encoders/decoders (explain).
2633 Bug fixed in DeleteRequest.
2635 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2637 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2639 Added SOIF syntax (using private OID for now) to retrieval module and client.
2641 Added Update extended service.
2643 Added SearchResult-1 additional info structure.
2645 Added optional CCL (ISO8777) interpreter as separate module. Available
2648 --- 1.2 1996/6/10 (1st anniversary release)
2650 Added Summary record syntax. Lightly tested.
2652 Added OPAC record syntax. Untested.
2654 Added ResourceReport service encoders/decoders. Untested.
2656 Fixed bug in z_Unit - wrong tagging on unitSystem.
2658 Fixed bug in the DiagRecs decoder.
2660 Added options for max PDU size and session timeout to frontend-server.
2662 Added documentation of query-language parsers and other supporting utilities.
2664 [frontend-server] Added Attribute set to the bend_scanrequest API.
2666 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2667 surrogate diagnostics were generated.
2669 [retrieval] Allow multiple local values for attribute.
2671 [retrieval] Allow multiple attributes per element in .abs files. index type.
2673 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2675 --- 1.1pl2 1996/4/10
2677 Minor changes, mostly specific to Zebra's requirements (retrieval)
2681 Repaired bug in frontend server when running multiple listening
2682 endpoints in dynamic mode.
2684 z_External() now won't break if a known, ASN.1 value comes encapsulated
2685 in an octet-string. The value will pass through unmodified in an Odr_oct.
2687 Added a bit of code to the demo client to decode & display
2688 ASN.1-structured records represented in the octet-aligned branch of
2689 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2691 Added z_ext_getentbyref() to the ASN module. Doc updated.
2693 * Completed the SCAN definition in the ASN module. This may break SCAN
2694 code based on older YAZ-versions at compile-time. The fix is easy -
2697 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2698 under the SCAN definition. Remember to initialize this, server-people.
2700 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2701 that this does not extend to ODR and ASN.
2703 Comstack allows insertion of established socket (primarily for
2704 inetd-operation of servers). Doc updated.
2706 Front-end server can now start from the inetd in TCP mode. Doc
2709 --- 1.0pl4 1996/1/24
2713 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2714 the rank and record number.
2716 Adjustments to the frontend server.
2718 Fixed diagnostic BER dumper. It ignored the file argument.
2722 Various changes to retrieval module.
2724 Changed the union discriminators of the protocol files from enums to
2725 ints paired with #defines.
2727 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2730 *Changed operator in the RPN structure to 'roperator', again to avoid a
2733 Fixed problems in Explain decoders/encoders.
2735 --- 1.0pl2 1995/12/6
2737 Memory bug in log module fixed.
2739 --- 1.0pl1 1995/12/5
2741 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2743 Bug in Explain DatabaseInfo module fixed.
2745 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2749 The shift to v1.0 signals that we now consider the *core* functionality
2750 of YAZ reasonably stable (the core being more or less equivalent to
2751 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2752 tested (Explain not at all - though that will happen soonish).
2754 Minor changes to code to support Windows port.
2756 Various minor changes after we're getting to use GRS-1 & co. more.
2758 Added Espec-1 format.
2760 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2761 of the protocol and it cannot be selected when encoding (maps into 'string'
2762 when decoding). Needed to talk to some servers.
2764 Demo client can request simple element set names.
2766 Added Diagnostic Format encoders/decoders.
2768 Added simple Close handling to frontend server (no hooks for resource
2769 reporting yet), and demonstration client.
2771 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2773 --- 1.0b3 1995/08/24
2775 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2776 handled incorrectly when records were requested in the searchResponse. This
2777 will only affect you if you use the frontend-server.
2779 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2780 Test-client will ask for and print GRS1. Ztest will return dummy records
2783 Added Explain encoders/decoders to the service-level API. Untested.
2785 Added Extended Services: Item Order encoders and decoders to the Service-
2786 level API. Untested. We could use a recent copy of the pertinent bits
2787 of the ILL protocol to add those bits.
2789 Added diagnostic format 1 encoders/decoders to the service-level API.
2792 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2793 odr_cons.c, which causes a more correct output.
2795 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2796 was always set to 0 when no records were requested in the searchRequest.
2798 * Added better external-handling. This shouldn't harm old code that
2799 *encodes* externals. It can break code that looks for a
2800 'single-ASN1-type' representation, since those types that are known
2801 are now decoded immediately. Look at the SUTRS sample code in
2802 seshigh.c and client.c. Documentation updated.
2804 Handling of structured records in bend_fetchresponse. Length -1 marks
2805 structured record, type is deduced from format field.
2807 --- 1.0b2 1995/06/27
2808 Fairly quick maintenance release to add SUTRS support.
2810 Fixed handling of SUTRS records in the demonstration client.
2812 * Added format field to the bend_fetchrequest and bend_fetchresponce
2813 structures of the backend API (frontend server). When the record is
2814 returned, the value of the format field is mapped to an OID. The
2815 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2816 of the record. The special value VAL_NONE in the bend_request means
2817 that no specific format was requested by the client. Documentation
2818 updated accordingly. Test server (ztest) will return a fixed dummy
2819 SUTRS record if your client requests SUTRS.
2821 Documentation updated accordingly.
2823 You can now set external libraries and RANLIB support in the top-level
2827 First public release.
