3 Fix yaz-config for static mode and the use of SSL (gnutls).
7 Forward decl timeval struct in mutex.h and gettimeofday.h.
9 yaz-config: fix 'static' mode linking.
13 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
14 are wrappers for pthreads or Windows. For Windows these are put in
15 a separate DLL: yaz_cond4.
17 libyaz.la (whole source) is compiled with thread. If thread support
18 is enabled enabled, all source of YAZ is compiled with treading support.
19 This allows core utilities such as yaz_log to use thread facilities.
20 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
21 thread utilities. This commit moves mutex utilities (mutex.c) from
22 libyaz_server.la to libyaz.la.
24 yaz-json-parse displays leading text until error.
28 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
29 patch from Giannis Kosmas.
31 SRU: no longer URL encode SRU database. The URL for an SRU server is
32 a URL and such is alreeady encoded - at least when given with leading
33 http:// or https://. This reverts behavior to YAZ 3.0.50.
35 Support for new MARC XML notation TurboMARC which like MARCXML is a
36 complete representation of MARC/ISO2709.. This one, however, is more
37 compact and allows for faster processing with XSLT. TurboMARC can be
38 used in the marcdisp.h API, from the yaz-marcdump utility and from
41 yaz-ztest can be configured - via the database - to perform certain
42 delays when it performs operations search, present and single record
43 fetch. This allows testers to make yaz-ztest act as a real or even slow
44 Z39.50 server. Refer to the yaz-ztest man pages for details.
48 wrbuf_destroy allows NULL WRBUF passed to it.
50 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
52 Add ZOOM_connection_close.
54 No fixed size buffers for ZOOM shell - bug #3257.
56 tstodr: make it work on s390 platform.
58 New icu iterator-functions. The new icu_iter-functions makes it possible
59 to use ICU chains from many threads.
61 yaz-client: better syntax check for show command.
65 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
68 New simple local-file XML include facility which allows file glob-patterns.
69 Refer to yaz/xml_include.h.
71 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
74 ZOOM_record_get supports new parameter "format" which makes it format XML
77 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
78 JSONText in ECMA-262) is JSONValue, not JSONObject.
82 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
83 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
85 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
86 POSIX/Unix builds .so with major version 4.
88 Remove old LOG_-defines from log.h. They have been obsolete and
89 undefined by default for the last 5 years.
91 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
93 GFS: Remove socket (int *fd) from search_rr handler. The socket
94 descriptor ptr is a facility that allowed a search handler to supply
95 a socket which would serve as a callback - when search was complete.
96 This facility has now been in use for years.
98 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
99 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
100 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
101 returns 'const char *' rather than 'char *. The returned string is
102 read-only and should not be modified by applications. COMSTACK cs_close is
103 now a void function - it no longer returns int. No applications check for
104 the value and the implementations has always returned 0.
106 ZOOM: use size_t for scan hit counts and str size. Functions
107 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
108 occ (hit count) and len (string length) are now of type size_t pointer
109 rather than int pointer. This is to be able to represent large hit counts
110 and to also just to use the proper type for string length (strlen result).
112 New JSON parser. Refer to include/yaz/json.h .
114 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
115 Used to be int in some cases. Many wrbuf_-functions used to return an int
116 indicating some length.. These return values were never used. And so they
119 ODR: odr_malloc, odr_total now takes size_t for size.
121 clone_z_type: fix leak; occurred for encoding failures.
123 --- 3.0.52 2009/12/03
125 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
126 bug was introduced in 3.0.51.
128 --- 3.0.51 2009/12/02
130 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
132 tcpip comstack: fix leak for getaddrinfo.
134 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
135 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
136 Decoding of SRU "path" database is performed by private function
137 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
138 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
140 yaz-client: honor base command for SRU. Change when database setting
141 is applied for SRU and ensure it is kept when a connection is reset.
142 Change also the way errors are displayed or SRU (decoding of packages).
144 --- 3.0.50 2009/11/02
146 Add support for extra request / response data for SRU codecs and GFS.
147 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
148 for extra data response buffer and length. For the GFS, both request
149 and response data (XML) is carried in extra_args and extra_response_data
150 for the search handler. Patch by Ko van der Sloot.
152 ZOOM: For queries that cannot be converted to the specified rpnCharset,
153 ZOOM now returns a diagnostic on the client-side ('invalid query' /
154 10010). This fixes bug #2113.
156 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
157 cmdfile included a 'quit' command that would result in a memory violation.
159 --- 3.0.49 2009/10/01
161 Make a number of functions defined in xmlquery.c static. These have
162 never been declared in a public header file (yaz/xmlquery.h) and was
163 made public by mistake.
165 Improve speed of character conversions (iconv utilities). This makes
166 conversions from MARC-8 faster.
168 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
169 unless type desired is "raw". This will prevent type "xml" from
170 returning ISO2709 .. Which obviously can not be XML parsed.
172 Fix memory leak in ZOOM that would occur if option apdulog was used
173 on a re-used connection.
175 Frontend server logs HTTP requests.
177 Frontend server now sends Z39.50 close when it times out (sesssion has
178 been idle for too long). Versions 2.0.30 and earlier also sent close.
179 But due to a mistake this was disabled in all versions after that, i.e.
180 the server would just close the socket immediately.
182 yaz-client emits a better message when receiving an unrecognised
183 userInformationField.
185 Skip zero-length subfields when decoding ISO2709. This rare case happens
186 if a record has two FS characters in a sequence. Without this patch
187 there would be a reference beyond char array in using_code_len fragments
190 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
192 --- 3.0.48 2009/08/28
194 The show command offered by the zoomsh command now takes a 3d optional
195 parameter type which is what is passed to ZOOM_record. If the type
196 argument is omitted, "render" is used.
198 RPN to CQL conv may use USE string attributes (bug #2978).
200 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
202 --- 3.0.47 2009/07/08
204 Function yaz_xml2query allows a diagnostic element in the PQF XML
205 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
206 code and additional info respectively.
208 The BER BOOLEAN is now the integral type Odr_bool which still happens
209 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
210 typedef'd to Odr_int. This is still an integral 'int', but it may be
211 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
212 ASN-1 compiler as well as programs has been updated to use the new types.
214 --- 3.0.46 2009/06/08
216 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
217 only the bibliographic record was rendered. For type=opac, an OPAC
218 record is only returned if it is present.
220 iconv: small fix for encoding of advancegreek.
222 yaz-client: avoid double display of SRU/SRW records (bug #2798).
224 yaz-client: option auto_reconnect=on really reconnects.
226 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
228 server: avoid null ptr ref for for yaz_poll errors.
230 build: fix RPM build for RHEL 5.3.
232 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
234 --- 3.0.45 2009/03/31
236 Fixed bug #2709: TCP connect returns Invalid argument.
238 Fixed compilation for mingw.
240 Honor charset for raw records (ZOOM_record_get).
242 Fixed use of errno for threaded mode that was seen on Solaris 10.
244 Fixed argument passing with blanks in value for Windows Service.
246 Disable YAZ' own log rotate by default (no 1 GB limit).
247 The variable l_max_size which specifies the log file limit is set to 0
248 (DISABLED): This is due to the fact that YAZ is most often deployed using
249 logrotate. Also YAZ can not perform log rotate because of unsufficient
250 permissions (setuid).
252 --- 3.0.44 2009/02/17
254 List supported encodings in man page for yaz-iconv.
256 Fixed missing SSL libs for --libs output
258 Re-established OID record syntax application-xml. Nobody should use it
259 but we don't want to change soname because of this symbol being absent.
261 --- 3.0.42 2009/02/02
263 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
265 Added member named_result_sets for init handler struct for the GFS. This
266 allows a server to disable named result sets.
268 Removed OID record syntax application-xml.
270 Added support for rule-based transliterator for ICU wrapper of YAZ.
272 Fixed bug #1902: yaz-icu XML output.
274 Make YAZ checks Emacs friendly.
276 BITSTRING value shows value. Bug #2346.
278 ISO2709 decoding: skip control characters from indicator data.
280 Omit sort key by default in yaz-icu's output.
282 Allow combined single char options (again) for YAZ' options function.
284 Utility yaz-marcdump got option to display YAZ version (-V).
286 Allow YAZ to use ICU 3.4.
288 Added new ICU test case which illustrates removal of diacritics.
290 --- 3.0.41 2008/12/29
292 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
294 --- 3.0.40 2008/12/29
296 For configure, using option --without-xml2 also disables Libxslt/Libexslt
299 Fixed bug #2352: yaz-marcdump crashes for certain record.
301 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
303 Added support for Danmarc2 to UTF-8 conversion.
305 Added support for ISO5426 to UTF-8 conversion.
307 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
308 implementation version.
310 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
312 --- 3.0.38 2008/11/10
314 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
315 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
317 ZOOM C now interprets databaseName option for ZOOM connection as path
320 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
322 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
324 Dummy Libxml2 types no longer defined in headers of YAZ'.
326 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
329 --- 3.0.36 2008/09/26
331 Various ODR chapter fixes.
333 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
335 Added missing source for Windows compilation, mutex.c.
337 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
339 For SRU connections in ZOOM all records up to "count" are now fetched.
341 Fixed crash in generic frontend server (and yaz-ztest) which occurred
342 in Windows due to bad error handling for Libxml2.
344 Added facility for sending arbitrary records (ASN.1 any) using
345 ZOOM C's Extended service update. Patch by Sam Reynolds.
347 New options for ZOOM C's connection, logapdu which makes ZOOM log
350 --- 3.0.34 2008/06/18
352 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
354 --- 3.0.32 2008/06/12
356 Fixed memory violation that could occur when decoding UTF-8. This bug
357 was only present in 3.0.30 of YAZ.
359 --- 3.0.30 2008/06/06
361 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
362 GNU TLS is used by default (if found).
364 yaz-ztest returns OPAC records if a client asks for OPAC.
366 Improved speed of MARC-8 encoding.
368 Added support for lossy and loss-less MARC-8 encoding.
370 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
372 Added new Windows Service wrapper (sc).
374 yaz-client's itemorder command may now send a file.
376 Fixed yaz-marcdump to allow the use of NS prefix for record element.
378 Added new function yaz_log_xml_errors.
380 Allow (but warn) unknown XML attributes in MARCXML parsing.
382 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
384 The UTF-8 to MARC-8 conversion now uses a different set of characters
385 for Greek symbols. Bug #2120.
387 --- 3.0.26 2008/02/21
389 Added yaz_daemon (daemon.h).
391 Fixed bug #2068: pkg-config trouble
393 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
395 --- 3.0.24 2008/01/28
397 Document --with-xml2 option.
399 Added OPAC XML XSD (etc/opacxml.xsd).
401 Allow glob mask for name attribute in retrieval element for the
402 generic frontend server's retrieval facility.
404 Changed yaz_poll_poll to return yaz_poll_except for all returned events
405 except POLLIN/POLLOUT.
407 Fixed error handling in cs_listen. Bug #2037.
409 --- 3.0.22 2008/01/20
411 Fixed version in yaz/yaz-version.h.
413 Fixed bug #2027: Crash when closing connection.
415 Changed configure so that ICU support is only enabled if only ICU
416 and Libxml2 is available (because the ICU chain is XML based).
418 --- 3.0.20 2008/01/15
420 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
421 is built. Only this DLL depends on the ICU runtime.
423 yaz-ziffy is no longer part of YAZ. It is distributed separately by
424 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
426 Changed license of CCL module to 'Revised BSD'. After consultation with
427 remaining members of the original EUROPAGATE consortium, we are re-issuing
428 the CCL module without a separate license. The software was developed by
429 Index Data as part of a research project. The special license was included
430 to help feed usage information back to the project consortium to support
431 project evaluation. At this time, the project consortium has long-since
432 disbanded, and the majority of the original principals have retired. At the
433 same time, we have significantly modified the software during the following
434 years, to the point where very practically no original code remains. To
435 simplify re-use of the software, we have contacted those members of the
436 consortium who could be reached, and agreed to re-issue the module as a
437 proper part of the YAZ package.
439 Tcl scripts uses /usr/bin/tclsh as preferred shell.
441 CQL closer to being version 1.2 compliant. CQL also allows free-form
442 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
445 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
446 bug could make Extended services handling crash in the ZOOM layer. This
447 bug was only present in YAZ 3.0.18.
449 --- 3.0.18 2007/12/19
451 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
454 yaz-marcdump reads and writes collection wrapped records.
456 Handle OPAC for record conversion module.
458 Fixes for ICU wrapper.
460 Allow ICU libs to be controlled with --with-icu .
462 --- 3.0.16 2007/11/12
464 Added yaz_poll which is a wrapper for select/poll. When poll is available
465 and non-buggy, it is used, by yaz_poll . This allows more than 1024
466 sockets to be in use.
468 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
469 functionality through an XML based configuration (ICU chain). This system
470 is useful for search facilities such as Pazpar2 and Zebra that needs to
471 perform tokenization of indexed material. The ICU code in a separate
472 library libyaz3_icu.a.
474 Added HTTP tunnel facility for COMSTACK, bug #1752.
475 This is a facility that allows a Web proxy, such as squid, to tunnel
476 Z39.50 traffic. This facility is "transparent" to must applications
477 using YAZ. It's enabled by using pseudo transport connect: followed by
478 the proxy address, followed by command, then follwed by he regular
479 "virtual" addresss. For example,
480 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
482 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
484 --- 3.0.14 2007/09/21
486 Fixed bad memory reference in ZOOM_record - cuased by member not being
487 initialized. This was a problem only in YAZ 3.0.12.
489 Fixed bug in conversion from MARC to XML: Non-XML characters in control
490 fields were not removed.
492 Changed the way C code is generated from codetables.xml. Made a MARC-8
493 conversion trie for each characterSet section rather than codeTable.
494 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
495 of codetables.xml from Larry Dixson, LOC. Bug #1464.
497 --- 3.0.12 2007/09/12
499 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
500 from ZOOM_record_error).
502 ZOOM C function ZOOM_record_get returns record schema for type="schema".
504 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
506 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
508 Better SRW-to-Bib-1 diagnostic mapping.
510 ZOOM C and yaz-client announces SRU version 1.2 by default.
512 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
515 Fixed in yaz_sru_decode to allow other version than 1.1.
517 --- 3.0.10 2007/08/22
519 Added support for SRU scan for ZOOM.
521 Added support for the use of the older versions or Extended Service
522 Update in ZOOM. To faciliate this, an option "updateVersion" may be
523 set to the version , 1=first, 2=second, 3=third. The third version is
524 what ZOOM C has used so far. And that, obviously, is the default.
526 Added support for CCL queries in Z39.50 queries sent to the GFS (and
527 therefore in Zebra and in SimpleServer-based applications). The new
528 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
529 qualifier file used to transform incoming CCL queries into Type-1 RPN,
530 which is passed into the back-end search callback function.
532 Added support for HTTP Basic authentication in clients: the SRU/W
533 codec encodes the username/password elements of the PDU structure
534 appropriately, and these may be set using the "user" and "password"
535 options in ZOOM-C applications (the same options that are used for
536 Z39.50 authentication).
540 Fixed bug #1208: SSL appears to be broken in ZOOM.
542 Fixed bug #1206: Libxml2 include path weirdness.
544 Added oid_name_to_dotstring.
546 Allow elementSetName to be specified for ZOOM C record update.
548 Allow waitAction to be specified for ZOOM C based for Extended Services.
550 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
551 syntax OID. Bug introduced in YAZ 3 series.
553 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
557 Fixed bug #1157: yaz-client does not read .yazclientrc from current
558 directory. yaz-client now reads commands from file given by option -f
559 if specified; then tries to read .yazclientrc in current directory.
560 Failing that, it reads .yazclientrc from user's home directory.
562 Added support for correlationInfo Note and ID for Record Update via
565 Added yaz-client command querycharset which specifies character set for
566 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
567 (termListAndStartPoint).
569 Charset ISO5428:1984 is an alias for ISO5428-1984.
571 Implemented a way to perform scan in a result set using Z39.50. This
572 is achieved by attaching the result set name in the characterInfo
573 (type InternationalString) of OtherInformation in the Scan Request PDU.
574 The result set is identified in the otherinformation by the new OID:
575 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
576 This allows for scan in result set and faceted search . Zebra did some
577 of this in the APT term using attribute type 8 and value being result
578 set. Using the OtherInformation approach for this is cleaner and easier
579 to work with in proxies and the like. This facility can be used in
580 yaz-client using new command setscan which takes a result set as first
581 argument, start position (APT) as second.
583 Changed decoding of SRU XML packed records to deal with servers that
584 have recordData with XML data with multiple root nodes. Also make
585 comparison for recordPacking case insensitive. Again, one server
586 returns "XML" where others return "xml".
588 For SRU responses allow Content-Type application/xml as well as text/xml.
592 Fixed bug in character set conversion of BER strings. Bug introduced
597 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
599 For OID class, use oid_class consistently.
601 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
604 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
605 character set for bibliographic information interchange". By Giannis Kosmas.
607 Added documentation on new OID API.
611 Changes to generic frontend server interface: added new member
612 'query_charset' for bend_initrequest structure. A backend init handler
613 should set this member to its native character set for query terms.
614 When defined, the frontend server logic will announce this character set
615 to a client if the negotiationModel bit is set by the client. All server
616 implementors are encouraged to specify this. If a backend server does not
617 specify this a warning is issued using yaz_log(YLOG_WARN,..).
619 Added CCL utility to remove terms (stop words) from resulting RPN
620 tree. This is handled by functions with prefix ccl_stop_words_ .
622 New ZOOM C option, "rpnCharset", which allows client-side conversion of
623 terms in RPN queries.
625 Clean-up the CCL API. Moved some internal structures from ccl.h to
626 private header cclp.h. Changed ccl_parser_create so that a Bibset must
627 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
628 This is replaced by ccl_parser_find_str which takes a string instead.
630 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
631 libyaz.la is the core of YAZ except the generic frontend server and
632 does not depend on POSIX threads anymore. libyaz_server.la is the
633 generic frontend server facilities and uses POSIX thread functionality
634 if available. The libyaz.la no longer depends on POSIX threads because
635 the number of global structures is limited. NMEM no longer re-uses blocks
636 between threads ; it simply free's memory immediately but allocates in
637 "large" chunks as usual. We don't expect any performance penalties
638 because of this. The yaz_log system is still using a global log_level so
639 caution must be taken when modifying it with yaz_log_init_.. +
640 yaz_log_mask_str. This, however, should not cause any trouble because
641 these functions are called during initialization of application code
642 anyway. `yaz-config --libs server` returns libs for server applications;
643 `yaz-config --libs` returns libs for non-server applications.
645 New OID database - with public definitions in oid_db.h. Removed old OID
646 database including the head oid.h and definitions such as enum oid_value
647 and struct oident. The new OID database uses the same string names as
648 before but the 'protocol' is gone. There are now only two representations
649 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
650 converts from string to OID; functions with prefix yaz_oid_to_string
651 converts the other way.
653 Change to emit_term() in CQL-to-PQF query translation: when a term has
654 the /regexp relation modifier, do not process it for leading and
655 trailing "^" and "*", which have quite different meanings in regular
658 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
659 write handlers no longer carries a 'last' parameter. This will make
660 yaz_iconv flush "less" characters. A flush is performed by call to
661 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
663 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
664 removed, because function yaz_query_to_wrbuf does the same.
666 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
667 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
669 Deprecated MARC utility functions removed.
671 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
674 Branch split: YAZ_2_1_55_branch
676 --- 2.1.54 2007/03/16
678 Fix to ZOOM-C so that transparent reconnection is properly handled on
679 connections that are in asynchronous mode.
681 Fixed compilation on OpenBSD 4.0.
683 Large strings in GRS-1 records are now properly displayed in yaz-client.
685 Added character conversion support for "advancegreek"; based on patch from
688 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
689 sequence is met. Before the error was not set so it would be unknown.
691 Adjust yaz-marcdump MARC reader so that it skips until record separator
694 --- 2.1.52 2007/03/07
696 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
697 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
698 fd_set structure used as a bitmask for the FDs to be selected on.
700 Using ACX_PTHREAD macro to check for POSIX threads.
702 Fixed have-vsnprintf check.
704 --- 2.1.50 2007/02/23
706 Fixes for configure on BSD. Bug #900.
708 Added snprintf/vsnprintf wrappers for systems that don't have
709 limits (heavens forbid).
711 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
712 created before all previous tasks were completed and removed from the
713 task queue, the new task could be removed by a mistake.
715 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
717 Implemented pass-through CQL-to-PQF conversions. Bug #861.
719 Fixed bug #832: Problem with MARC/charset in yaz-client.
721 Fixed bug #668: save command line history for yaz-client.
723 Fixed bug #830: pkg-config support.
725 --- 2.1.48 2007/01/23
727 Extended ZOOM result set options with two options that may be read by
728 a client: resultSetStatus and presentStatus with values as specified for
730 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
732 Fixed bug #827: Using SSL fails on Debian etch.
734 Fixed bug #826: Weird looking chars for set of MARC records.
736 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
737 that is treated as an ItemOrder with itemRequest being an XML document
738 external. The value of "doc" is the content.
740 Extended the GFS search facility. New member of bend_search_rr
741 'estimated_hit_count' signals that hits is known to be an estmate
742 (higher or lower than real hit count). New member 'partial_resultset'
743 signals that the search was partial (hit count is lower or equal than
744 real hit count). For Z39.50, the information is stored in resultSetStatus
745 member of SearchResponse APDU. For SRU, the information is signalled
746 via SRU diagnostic 59: "Result set created with valid partial results
749 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
751 --- 2.1.46 2007/01/13
753 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
755 Added ZOOM_connection_peek_event.
757 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
758 the following new functions:
759 ZOOM_event_nonblock, ZOOM_connection_process,
760 ZOOM_connection_get_{socket,mask,timeout},
761 ZOOM_connection_fire_event_{timeout,socket}.
762 The existing blocking event handler, ZOOM_event, is a wrapper for the
763 + blocking ZOOM_event_sys_{poll,select}.
765 Implemented function ccl_xml_config which parses XML version of CCL
766 configuration (bug #798).
768 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
770 Added timings utility (yaz/timing.h)
772 --- 2.1.44 2007/01/03
774 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
777 Fixed bug #779: Rotation of apdu.log fails.
779 Fixed for character set conversions:
780 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
781 Honor G1 set in MARC-8 decoding.
783 --- 2.1.42 2006/12/17
785 Fixed bug #775: char conversion does not handle Alternative UTF-8
788 Implemented function yaz_marc_read_line which parses MARC line format
789 records. There is a wealth of formats out there. So far, this function
790 reads line records produced by yaz_marc_write_line.
792 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
793 more generic and easier to remember(!) options: -i format and -o format
794 which specifies input format and output format respectively - where
795 format is one of "marc", "marcxml", "line", "marcxchange".
797 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
798 does not print anything except warnings for records.
800 For yaz-marcdump, added support for MARC split into files (-s) with a given
803 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
804 spec, at http://www.loc.gov/standards/sru/record-update/
805 This has changed the binary layout of the following structs:
806 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
807 bend_update_rr . Patch by Ko van der Sloot.
809 Added GFS utility function bend_assoc_is_alive which returns 1 if
810 association is still alive (client is connected); 0 otherwise (client
811 closed connection). This allows busy servers to stop working for
814 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
815 been a separate piece of software. This version of ziffy has been modified
816 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
818 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
820 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
821 Client code may now interrogate options such as "init_opt_sort" to
822 find out whether the server claims to support various options.
824 --- 2.1.40 2006/11/27
826 Added utilities yaz_{set,get}_esn to set/get element set name from
829 Removed the build of libyazthread.la. The libyaz.so is the threaded version
830 of YAZ and has been so since YAZ 2.1.10.
832 Implemented ZOOM_record_error which returns error information for
833 record (surrogate diagnostic).
835 --- 2.1.38 2006/10/31
837 Updates for SRU Update by Ko van der Sloot:
838 1. Changed name from "operation" to "action"
839 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
840 versions in the code, marked as 'backward compatible'.
841 3. Added diagnostics for SRU Update.
843 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
845 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
847 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
849 For GFS, fixed problem with SRU diagnostic 'First record position out of
850 range' being issued for 0 hits.
852 zoomtst10 part of Windows Build.
854 --- 2.1.36 2006/10/13
856 Implemented yaz_filepath_comp which splits a path into file path
857 components (required by Zebra 2.0.3+).
859 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
860 BSD inspired license until now so this should not have any real impact on
861 anybody. See http://www.opensource.org/licenses/bsd-license.php
863 Fixed bug #687: Missing log lines.
865 Fixed bug #678: CQL to PQF translation does not preserve double-quote
868 Fixed bug #689: SRU diagnostics to be added.
870 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
871 whether a connection is idle (no more work do do).
873 --- 2.1.34 2006/10/04
875 Change type of optval from long to int for invocation of setsockopt with
876 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
878 Added support for specifying the max log file size for the Generic
879 Frontend Server. The size is given with option -r.
881 --- 2.1.32 2006/09/21
883 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
885 --- 2.1.30 2006/09/17
887 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
890 Fixed bug in Generic Frontend Server that could cause a server to stop
891 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
893 For the generic frontend server, the maximum record size is used as maximum
894 size of incoming packages (SRU + Z39.50). The value until was previously
895 only used in Z39.50 Init negotiation and, later, in a session controlled
896 sizes of records returned. This is controlled using -k option. It can be
897 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
899 --- 2.1.28 2006/09/04
901 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
904 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
906 New option for yaz-marcdump -lpos=value which allows setting a portion
907 of MARC header to a certain value.
909 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
911 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
912 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
914 --- 2.1.26 2006/08/15
916 Fixed problem with SRU mode type (soap, get, post) for yaz-client
919 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
921 --- 2.1.24 2006/08/08
923 Fixed MARC ISO2709 encoding routines to deal with character set
926 Minor changes to GFS logging. Database included in search request log
929 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
930 cached/multiple records.
932 Shared libraries are built by default on Unix+configure.
934 Changed cql2pqf transformation to use a different evaluation order. The
935 new order is: always, relation, structure, position, truncation, index
936 and relationModifier. Old order was: always, relation, relationModifier,
937 structure, index, position, truncation. Note that the the latter ones
938 override former ones for identical attributes.. The new scheme means that
939 it is possible to override any existing attribute with a relationModifier.
940 And also that it is possible to override everything for the index rule
941 (except the ones listed in relationModifier). No order is perfect but this
942 one, we believe, covers more real cases.. The "always" should have been
943 called "default", since the attributes there can be overridden with all
946 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
947 compilation phase, but also for yaz-config --cflags output. This allows
948 us to have public headers with Libxml2 stuff in them . It should also,
949 eventually, make Libxml2 checks redundant in packages using YAZ, such
952 --- 2.1.22 2006/06/15
954 Changed SRU update structure bend_update_rr so that SRU diagnostics are
955 stored in uri, message and details.. Previously diagnostics were stored
956 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
957 compatibility.. but he's probably the only one affected, so.
959 Added support for CCL, compiled on the client side, in ZOOM-C. This
960 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
961 input; the resulting query objects can be used for for searching with
962 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
964 YAZ' configure searches for OpenSSL by default.
966 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
967 SL_CTX_use_certificate_file. See
968 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
969 for more info. Thanks to Ko van der Sloot.
971 --- 2.1.20 2006/06/02
973 Bug #600: SRU GET, POST support for yaz-client. Introduced
974 command 'sru' which selects method SOAP/GET/POST.
976 Allow missingValueAction to be specified for the sortspec string -
977 function yaz_sort_spec. By default, the missing value action is null.
978 Use ! to specify "abort". Use = followed by stringvalue to specify default
981 Ensured that Present-handler (if defined) is called in GFS before any call to
982 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
983 searchRetrieve requests.
985 Documentation for YAZ is now based on the Docbook XML/XSLT using
986 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
987 is no longer depending on jade/openjade or docbook-to-man scripts.
988 PDF is no longer part of the distribution - but can optionally be
989 made using DSSSL/jadetex or FOP.
991 Added retrieval handling support in Generic Frontend Server to support
992 conversion between MARC/XML as well as XSLTtransforms. See
993 etc/yazgfs.xml for an example.
995 Added Authentication support to Generic Frontend Server in SRU
996 mode. Authentication using HTTP Basic is supported, as is the use
997 of 'x-username' and 'x-password' parameters in the request itself.
999 Added support for a new character set MARC8s identical to MARC8 except
1000 that it converts combined characters to single Unicode characters in the
1001 Latin-1 range (when possible).
1003 --- 2.1.18 2006/04/24
1005 ASN.1 compiler 0.4: generates brief Doxygen file header for
1006 generated .h/.c files.
1008 Utility yaz_iconv now supports conversion to MARC-8.
1010 New facilities for the MARC module. The reading - and writing of
1011 content are separate methods for the yaz_marc_t handle. The following
1012 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1013 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1014 format). Write functions have prefix yaz_marc_write_.. The existing
1015 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1016 available. Removed support for OAI-MARC and simplexml (not the
1017 simplexml from PHP5).
1019 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1020 to be returned for this connection.
1022 --- 2.1.16 2006/03/31
1024 Allow multiple languages and charsets to be specified with
1025 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1026 negcharset iso-8859-1,utf-8
1028 Translation of proximity nodes from CQL into PQF now works.
1030 Moved to automake 1.8, 1.9.
1032 Added function yaz_log_set_handler which allows a log handler to be
1033 installed. This handler will be called for all log messages. Output
1034 to file is also produced; but that can be disabled by passing NULL
1035 fname to yaz_log_init_file.
1037 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1039 For SRW (including GFS), accept application/soap+xml as content-type
1042 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1043 produces NO stylesheet reference even if a default stylesheet is specified
1046 --- 2.1.14 2006/03/14
1048 Updated Windows package to include yazd.dll + yazd.lib for the
1049 Development component.
1051 If the environment variable YAZ_LOG is set, then it is used as a
1052 string indicating the default level of logging to use if not
1053 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1054 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1055 used as before. So, for example, to omit warnings from YAZ logging,
1056 export YAZ_LOG=-warn
1058 cql_transform() now map structure and other attributes before indexes,
1059 so that index-specific structures and other attributes can override
1060 defaults. So now a combination of mapping specifications such as:
1062 index.dc.date = 1=date-modified 4=5
1063 does the right thing.
1065 cql_transform() now also respects the "always" mapping specification,
1066 which establishes an initial set of attributes to be used for all
1067 terms except where overridden by more specific attributes associated
1068 with the index, relation or modifier.
1070 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1071 which mode to use; one of "post", "get" or "soap" (SRW, default).
1073 Fixes for yaz_iconv routines: changed trie-based character set conversions
1074 to use only non-negative values for bit fields due to Sun's C compiler not
1075 supporting negative values.
1077 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1078 sequences where not read correctly. Fix by Rustam Usmanov.
1080 Updated win/makefile to use options, settings which makes things
1081 compile with VS C 2005.
1083 --- 2.1.12 2006/02/01
1085 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1087 In ZOOM socket code, use select instead of poll on MacOSX.
1089 ZOOM-C now support client-side compilation of CQL into RPN that is
1090 sent to the server, enabling CQL to be used against all Z39.50
1091 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1092 ZOOM_query object, and submit it using ZOOM_connection_search().
1093 The CQL-to-RPN translation uses a configuration file, the name of
1094 which must be specified in the Connection's "cqlfile" option.
1096 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1097 function, which takes as its start-term parameter a ZOOM_query object
1098 (which may have had either CQL or RPN set into it).
1101 --- 2.1.10 2005/11/29
1103 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1104 GFS to support this as well. Backend handler, bend_srw_update, does the
1105 update work. Code contributed by Ko van der Sloot.
1107 Allow retrieval of Search Result-1 information in ZOOM by the use of
1108 options that are attached to a result set. ZOOM documentation updated
1111 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1112 UTF-8 conversion. Patch by Raj Patel.
1114 Added option -m to GFS to control formatting of timestamps in log file.
1116 Added 'exit' as synonym for 'quit' in yaz-client
1118 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1119 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1120 for the new members. Patch by Ko van der Sloot.
1122 Added support for SRU POST. It is supported for content-type
1123 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1125 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1126 Instead make the library libyaz.la multi-threaded. Threading as a whole
1127 can still be disabled by configure option --disable-threads. Previosly,
1128 with older GLIBCs there were problems with MT libs under Apache. This
1129 has now been fixed a long time ago.
1131 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1134 CQL module modified to be case insensitive for relations/indexes/operations.
1136 Fixed bug in CQL transform code: incorrect value relationModifieder
1139 Added 'show all' command for yaz-client which retrieves all results
1142 Added new yaz-client, xmles, which takes a (private) OID and
1143 a document to be sent as an extended service request.
1145 Describe new yaz-client commands wait_response and set_auto_wait.
1147 Increase TCP/IP listener backlog from 3 (which I am guessing was
1148 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1149 that the socket will queue as many incoming connections as it's able
1150 to handle ongoing connections. In other words, it will never now
1151 refuse a connection that it would be able to handle merely because
1152 it's not got around to accepting() enough of the pending connections
1153 yet. This is the behaviour anyway under Linux, where the listen()
1154 argument is ignored; but not under BSD and on systems such as
1155 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1156 YAZ-based servers should now be uniform across operating systems in
1159 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1160 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1161 This allows yaz-marcdump to read large MARC batches (>2 GB).
1163 Modified all YAZ source files - except the source which is auto-generated
1164 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1167 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1168 corresponding to the existing *_setl() function. These allow option
1169 values containing arbitrary valuues.
1171 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1172 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1173 except that it returns an indicator of whether or not the sort
1174 criterion was accepted (0 for OK, -1 for invalid).
1176 --- 2.1.8 2005/06/07
1178 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1179 MARC output rather than returning "new" buffer.
1181 yaz-client warns about unknown init options.
1183 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1185 --- 2.1.6 2005/05/24
1187 Added support for SRW sort in Generic Frontend Server. Patch
1188 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1189 sortKeys - or NULL if none is provided.
1191 Fixed bug #307: It was impossible to specify indefinite/no timeout
1192 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1195 Added support for multiple languages and charsets to be specified in
1196 ZOOM. Each charset/language is separated by a blank. If negotiation is
1197 in effect in init-response, Option
1198 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1199 Code based on patch by Vasiliy Osadchuk.
1201 Fixed bug #306: infinite recursion that occurred when calling
1202 yaz_log_level_init as the first call (before other log level or
1205 Fixed bug in scan handling in front end server: if preferred-Position-In-
1206 Response was non-present, a NULL pointer referece was performed.
1208 --- 2.1.4 2005/04/26
1210 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1211 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1212 now defined for all those error codes. So instead of putting 109 in
1213 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1214 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1216 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1219 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1221 Program yaz-client now exits and produces an error message if multiple
1222 Z39.50 servers are specified on the command line (none or one allowed
1225 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1228 --- 2.1.2 2005/03/16
1230 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1232 Fixed bug #272: Preserve spacing for CCL terms.
1234 --- 2.1.0 2005/03/14
1236 Added support for virtual hosts and multiple backend servers for
1237 the YAZ frontend server. The configution is XML based and
1238 support specificition of CQL to RPN mappings and explain information.
1239 See section "Virtual Hosts" in the YAZ manual.
1241 Extended OPAC display utility. OPAC display utility renders
1242 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1243 to supplement yaz_marc_decode_wrbuf.
1245 Fixed a bug in MARC decoder that could caused it to crash for some
1246 invalid MARC records. More diagnostics and warnings where added in
1247 XML output (warnings, etc are stored in comments).
1249 --- 2.0.34 2005/02/08
1251 Fixes for UNIX domain sockets. Bug #261.
1253 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1255 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1256 Added yaz_marc_subfield_str which defines subfield lead string which is
1257 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1258 yaz_marc_endline_str which defines end of fields string used in
1259 YAZ_MARC_LINE format. Default string is newline.
1261 Experimental support for MarcXChange. This format can be produced
1262 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1263 http://www.bs.dk/standards/MarcXchange.xsd
1265 Added yaz-client commands scansize that sets maximum number of
1266 entries to be returned by scan.
1268 --- 2.0.32 2005/01/11
1270 Added support for SRW scan in yaz-client and Generic Frontend Server.
1272 * Added whereInList member to SRW Scan Term.
1274 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1276 Fixed NMEM system to return aligned blocks on the smallest boundaries
1277 that are suitably aligned for all possible types on the particular
1278 architecture YAZ is being built for.
1280 --- 2.0.30 2005/01/04
1282 Fixed numerious warnings that was issued with newer versions of GCC.
1284 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1285 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1288 Make YAZ Generic Frontend Server slightly faster.
1290 Enhance (and reduce) logging for Generic Frontend Server.
1292 Revert YAZ log system so that it flushes every write operation
1293 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1295 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1296 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1297 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1298 will effectively disable old definitions.
1300 --- 2.0.28 2004/11/09
1302 Added yaz_log_time_format which specifies log format using
1305 Added yaz_log_module_level which returns mask for a module. Value
1306 is non-zero mask a if module is enabled; zero if disabled.
1308 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1309 in include/yaz/cql.h.
1311 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1313 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1315 Fixed bug #172: RPM builds does not enable SSL.
1317 Doxyfile.in part of dist. Doxyfile generated by configure.
1319 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1320 are given and the corresponding component does not exist.
1322 Extend CCL documentation in YAZ reference. Describe r=r.
1324 --- 2.0.26 2004/10/01
1326 Fixed MARC->MARCXML conversion to properly deal with
1327 fields, subfields, indicators having non-ASCII characters.
1329 Fixed MARC->MARCXML conversion so that ASCII control characters
1330 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1333 Added YAZ GFS support for conversion from Z39.50 surrogate
1334 diagnostics to SRW surrogate diagnostics.
1336 Bug fix: YAZ GFS did not return schema in explainResponse.
1338 --- 2.0.25 2004/09/30
1340 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1341 now converts recordSchema to elementSetName as well as schema URI.
1343 Fixed bug in COMSTACK that prevented HTTP request packages from being
1346 --- 2.0.24 2004/09/29
1348 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1349 does not require white-space before and after the dash in a range, e.g.
1350 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1353 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1354 due to new GCC removing "redundant" code.
1356 Added yaz-client commands scanpos and scanstep that sets preferred
1357 position and step-size for scan.
1359 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1361 Added CCL utility ccl_qual_buf which parses one or more CCL
1362 spec lines in a buffer.
1364 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1365 of name and value - ignoring empty lines and comments.
1367 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1369 Added odr_get_element_path which returns current element path for an
1370 ODR handle. This utility is useful in error handling or user-defined
1373 Added ODR_PRINT utility odr_set_stream which is is a more generic
1374 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1375 to a write function and pointer to close function. The close function - if
1376 non-NULL - will be called during odr_destroy.
1378 Fixed bug in CCL parser where truncation char was not removed from
1379 right side when truncation=both was in effect.
1381 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1384 --- 2.0.23 2004/08/11
1386 Fix buffer overrun in CQL parser when dealing with proximity (%).
1388 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1389 to UTF-8/UCS conversion is now only based on codetables.xml.
1391 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1393 --- 2.0.22 2004/08/06
1395 Add support for more "commit changes" in ZOOM (uses Extended Services).
1397 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1400 Yet another small fix for configure of SSL.
1402 --- 2.0.21 2004/05/14
1404 Fix SSL libs for configure when --with-openssl=DIR is given.
1406 --- 2.0.20 2004/05/10
1408 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1410 SSL comstack now uses yaz.pem certificate file on server side
1411 by default. Certificate filename can be configured by calling
1412 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1414 Fix bug regarding multiple calls to ZOOM_connection_connect.
1416 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1418 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1419 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1421 ZOOM now allows inspection of X509 peer certificate for verification.
1422 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1424 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1425 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1426 as "modular" but it simplifies things.
1428 Added cs_get_peer_certificate to that returns peer X509 PEM.
1430 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1431 NULL if SSL is unavailable.
1433 Documentation about MARC decoding tools.
1435 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1437 --- 2.0.19 2004/03/30
1439 Rename CHANGELOG to NEWS to follow GNU style packing.
1441 Fix bug with missing initialization of member in init_diagnostics.
1442 This bug affects threaded version of GFS server.
1444 --- 2.0.18 2004/03/20
1446 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1449 Ensure zlib.dll is packed with Windows install.
1451 --- 2.0.17 2004/03/17
1453 Fix encoding of xsd:string to use text instead of CDATA.
1455 Fix endless loop in CQL parser with unbalanced ".
1457 Use a more compact way to store MARC-8 conversion tables.
1459 --- 2.0.16 2004/03/16 Debian only
1461 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1464 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1469 --- 2.0.15 2004/03/01
1471 Another fix for decoding of XML packed records.
1473 --- 2.0.14 2004/02/25
1475 Fixes for Chunked encoding. White space not ignored after length spec.
1477 Update NS and use default NS for SRW diagnostic elements.
1479 --- 2.0.13 2004/02/23
1481 Implement ZOOM_resultset_cache_reset which resets record cache.
1483 Implement ZOOM_resultset_sort which sorts a result set.
1485 Implement chunked HTTP transfer.
1487 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1489 --- 2.0.12 2004/02/16
1491 Added member 'schema' to bend_explain_rr structure so that backend
1492 can specify explain record identifier. Defaults to Zeerex 2.0.
1494 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1496 --- 2.0.11 2004/02/16
1498 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1501 Added init command for yaz-client which sends "extra" init request.
1503 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1504 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1506 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1508 Make ZOOM error code for "invalid query".
1510 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1512 --- 2.0.10 2004/02/05
1514 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1517 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1519 Added option -p <file> to make Generic Frontend Server to write PID file.
1521 Added option -D to put Generic Frontend Server in background on its own.
1523 Make ZOOM C recognize option "password". If unset, "pass" is used
1524 (for backwards compatibility).
1526 Fixed a bug in Generic Frontend Server that could make it crash if a
1527 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1530 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1531 Must be issued before open, in order to be in effect.
1533 --- 2.0.9-6 2004/01/12 Debian/Windows
1535 Make the SRU server more picky WRT unknown params, etc.
1537 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1539 New YAZ client command, options, that sets Z39.50 options.
1541 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1542 options from a string of tokens (one token for each option bit).
1544 Update SRW diagnostic code messages.
1546 --- 2.0.9-5 2004/01/07 Debian/Windows
1548 Handle user defined stylesheet for SRW/SRU.
1550 --- 2.0.9-4 2004/01/06 Debian/Windows
1552 Fix bug in decoding of Content-Length.
1554 --- 2.0.9-3 2004/01/06 Debian/Windows
1556 Fix a bug with decoding of XML packed records.
1558 --- 2.0.9-2 2004/01/05 Debian only
1560 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1562 Fix bug in SRW/SRU diagnostics decoding.
1564 --- 2.0.9 2004/01/05
1566 Fixed bug in Generic Frontend Server which could drop records exceeding
1567 preferred message size. Reported and fixed by Irina Dijour.
1569 Fixed calculation of package size for structured records in Generic
1570 Frontend Server. Reported and fixed by Irina Dijour.
1572 Fixed namespace for SRW/SRU diagnostics.
1574 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1576 --- 2.0.8 2003/12/22
1578 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1579 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1582 CQL changes to reflect recent changes to the specification:
1583 * Documentation talks about context sets instead of index sets.
1584 * Documentation talks about indexes instead of qualifiers.
1585 * The CQL-to-PQF transformer's configuration file now uses
1586 "index.set.name = <attributes>" instead of the old form
1587 "qualifier.set.name = <attributes>". (Both forms are still
1588 understood but the latter is deprecated.)
1589 * CQL terms with no explicit index specified are now interpreted as
1590 cql.serverChoice instead of srw.serverChoice (which of course
1591 behaves exactly the same.)
1593 --- 2.0.7 2003/12/16
1595 MARC conversion can now generate ISO2709 output in another
1596 character set. yaz-marcdump uses this facility if you invoke it
1599 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1600 functions from there can be used from C++.
1602 --- 2.0.6 2003/12/04
1604 Frontend server now transfers memory from decoded packages to stream
1607 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1608 references to show up.
1610 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1611 the ZOOM Abstract API. The older names for the same options are still
1612 also supported for the benefit of old applications.
1614 ZOOM-C supports "implementationId" and "implementationVersion" options
1615 to go along with "implementationName". These allow the user code to
1616 specify identification strings to be sent to servers.
1617 Add OID for the new ExtLite attribute set.
1619 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1620 as requested/supplid by Ere Maijala <ere@atp.fi>
1622 For generic frontend server, reverse the order of
1623 "toolkit-supplied / application-supplied" strings sent as implementationId,
1624 Name and Version. Also, remove the spaces around the slash. This brings
1625 the GFS in line with the behaviour of ZOOM-C on the client side.
1627 Add function ZOOM_scanset_display_term.
1629 yaz-client shows scan displayTerm if present.
1631 Utility yaz-iconv is now installed by default along with the man page
1634 Extend configure check for OpenSSL to use pkg-config where available (such
1637 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1638 server to specify uid/gid/mask for socket using the format
1639 unix:[user=uid,][group=gid,][umask=mask,]file=path
1640 If file= is omitted the existing format is assumed, e.g.
1642 in which case the mask is 0666 (rw for everybody).
1644 Major restructure of YAZ source. All source in libyaz is in src directory.
1645 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1646 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1648 Added man page for utility yaz-marcdump (used to be called marcdump).
1649 yaz-marcdump is installed by 'make install'.
1651 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1652 of incoming package failed.
1654 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1656 Change prototype of odr_perror: add const to message string.
1658 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1660 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1661 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1662 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1663 DNS lookup. There should not be any compatibility problems with this
1664 assuming that blocking=1 or 0 is used.
1666 Fix bad reference in UNIX comstack in function cs_addrstr.
1668 Fix for compilation on AIX.
1670 The generic front-end server (server/seshigh.c) now supports returning
1671 Init diagnostics to the client in User-information-field, in
1672 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1675 --- 2.0.4 2003/09/04
1677 Allow any CQL relation (not just all,any,exact,scr).
1679 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1680 that features the same UI.
1682 Implemented command update0 in YAZ client which is equivalent to
1683 update but uses old of Ext Update ASN.1.
1685 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1686 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1687 Previously no OID was used for this info.
1689 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1690 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1691 returns 'malformed search term' otherwise.
1693 SortResponse member resultCount now set to NULL in sort handler of
1696 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1699 Add three new utility functions for translating OIDs between various
1700 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1701 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1702 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1703 char *oid_to_dotstring(const int *oid, char *oidbuf);
1704 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1706 Reverted modifications for ES Update definition for z_IU0Update
1707 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1708 is back to YAZ 2.0.2.
1710 String value attributes for CCL parser.
1712 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1713 which their FirstSearch server returns in Init responses, sometimes
1714 carrying useful diagnostic information when Init fails. This has the
1715 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1716 "z39.50/oclcui.asn", where its definition is somewhat different from
1717 what OCLC document on their web-site, as required to interoperate with
1720 Support for anonymous authentication in yaz-client. Use the command
1723 * Fix the OID of the Index Data-local "admin" Extended Service from
1724 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1725 the 1000, which indicates a locally-defined OID, was a mistake.
1727 --- 2.0.3 2003/06/20
1729 Fix CCL directive @case handling so that it affects string match for
1730 both CCL keywords and qualifiers.
1732 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1733 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1734 Decoder has been updated with ASN.1 changes as listed in
1735 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1736 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1737 z_IUUpdate, remains unchanged.
1739 ZOOM_record_get may now return a record in a specific character set.
1740 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1741 "from" is the character set of record as returned by target. "to" is
1742 the character set to be returned. If omitted, "to" is UTF-8.
1744 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1746 New ODR utility, odr_getelement, which returns name of element for
1747 which encoding/decoding failed.
1749 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1750 in cases where a required element was omitted.
1752 Bug fix: some MARC8 sequences were not converted.
1754 New ZOOM option "step" which specifies number of records to be
1755 retrieved in one chunk. Used in conjunction with "start" and "count".
1757 SRW support for yaz-client. Use scheme http: to use it, e.g.
1760 yaz-client no longer does (un)intelligent character set conversions
1761 by default. Can be enabled with charset and marc_charset commands.
1763 xmalloc trace fix for 64-bit systems such as DEC alpha.
1765 Solaris 2.6 compile fix.
1767 New function, cql_strerror() translates SRW error codes, as returned
1768 by cql_transform_error(), into human-readable English strings. Used
1769 in yaz-client diagnostics when appropriate.
1771 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1772 converts it into a type-1 query which is sent to the server. This
1773 makes CQL available for use with all Z-servers, as opposed to the tiny
1774 minority that can handle CQL queries themselves.
1776 --- 2.0.2 2003/04/28
1778 New Debian package layout similar to the Redhat Package layout.
1780 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1781 and search result respectively.
1783 --- 2.0.1 2003/04/25
1785 Redhat package is now several packages: libyaz (runtime libraries),
1786 libyaz-devel (development and documentation, and yaz (utility programs).
1787 Package spec file by Morten Bogeskov.
1789 New member 'schema' in struct bend_fetch_rr which the name of requested
1790 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1791 handler MAY set this to reflect the schema of the returned record.
1793 New member 'display_term' in struct scan_entry. GFS now sets member entries
1794 and allocates scan entries to be filled by user scan handler. In previous
1795 version, entries member was allocated by the scan handler. That still works,
1796 but the GFS will ignore member display_term - assuming it was NOT set by
1797 the handler. The fact that the GFS now allocates the entries both allows
1798 for new members and makes a scan handler easier to write.
1800 Fix CQL lex buffer overflow.
1802 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1803 SRU default recordPacking is string.
1805 SRU protocol support for frontend server.
1807 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1809 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1811 Added scan for the ZOOM shell (zoomsh).
1815 * String Identifers for Schemas (Amendment 5).
1816 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1817 Old definition for schema
1818 Odr_oid *schema; /* OPT */
1823 Z_InternationalString *uri;
1824 #define Z_Schema_oid 1
1825 #define Z_Schema_uri 2
1828 * resultCount parameter to Sort Response (Amendment 1).
1829 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1831 Support for SRW 1.0 over HTTP. This is an optional feature and
1832 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1835 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1836 on the same port. SRW SearchRetrieveRequests are mapped
1837 to bend_init,bend_search,bend_fetch,bend_close.
1839 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1841 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1842 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1844 ZOOM connections are SRW based if schem http is used for hostname
1845 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1846 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1848 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1849 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1850 distance=n, order=true/false, relation=le, prox unit=word. If
1851 n is omitted, distance 1 is used.
1853 Fixed problem with C compiler include path in wrong order.
1855 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1856 on Solaris. Patch from Ko van der Sloot.
1858 New MARC decode API. All new functions operate on a yaz_marc_t
1859 handle. The most important new functions are: yaz_marc_create,
1860 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1861 decode and destroy respectively. Decoder can produce formats
1862 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1863 include/yaz/marcdisp.h.
1865 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1866 to UTF-8, UCS-32, wchar_t or Latin-1.
1868 * Prototypes for yaz_iconv_-functions moved to separate header
1869 include/yaz/yaz-iconv.h.
1871 Make a few private functions 'static' in unix.c. This prevents
1872 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1874 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1875 are set when Init Response is received.
1877 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1878 but returns diagnostic set as well.
1880 New function yaz_strerror which is a portable wrapper for
1881 strerror/strerror_r/GetLastMessage.
1883 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1884 is returned for MARC. If type is "oai", then OAI MARC is returned.
1886 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1889 --- 1.9.2 2002/11/26
1891 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1893 Fix bad race conditions on SIGTERM and terminate gracefully in
1896 Move retrieval (data1) module to Zebra since nobody seems to be
1899 Add GRS-1 render for ZOOM using same format as yaz-client.
1901 --- 1.9.1 2002/10/05
1903 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1905 Fix broken ESpec handling in data1 module.
1907 SGML reader parses comments and makes them part of the data1 tree.
1909 Added several type casts so that YAZ compiles as C++ code.
1911 ZOOM didn't handle PDU encoding failures properly.
1913 Added more Bib-1 diagnostics (approved extensions).
1915 GNU configure: better check for iconv.
1917 More portable use of accept, getpeername. Check for socklen_t. Use
1918 int/size_t if socklen_t is not defined.
1922 PQF parser rejects bad queries - including those with extra
1923 characters in them. PQF parser used to silently ignore that.
1924 Cleaner API for PQF added, which allows you to get detailed
1925 error information for bad queries (see yaz/pquery.h).
1927 Fixed bug in ZOOM_record_get for type "database".
1929 Implemented mini iconv library supporting conversions between
1930 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1932 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1934 --- 1.8.9 2002/08/20
1936 Fixed ZOOM C record cache so that preferredRecordSyntax and
1937 elementSetName is used to check for already fetched records.
1939 --- 1.8.8 2002/08/02
1941 Added three members in bend_initrequest structure to facilitate
1942 character set negotiation.
1944 Fixed a bug in frontend server that could cause indefinite
1945 loops under rare conditions.
1947 Revised character set utilities (charneg.h) so that encoding
1948 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1950 For PQF, directive @term <type> sets term type for Scan/Search.
1951 Here <type> is general, string, numeric, null. The term type
1952 is inherited - just like @attr.
1954 New call odr_set_charset that sets character set conversion for
1955 international-strings on a ODR stream. Prototype is:
1956 int odr_set_charset(ODR o, const char *to, const char *from);
1957 The InternationalString is still represented as C string in YAZ
1958 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1959 won't). On the protocol level, you can use any encoding.
1961 Support for UNIX sockets in ZOOM.
1963 Solaris recv sometimes returns errno == ENOENT. It is treated as
1964 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1966 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1967 both client and server. Code by Morten Bogeskov.
1969 --- 1.8.7 2002/05/22
1971 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1972 that they can be used directly from Visual Basic. You must recompile
1973 your windows APP if you're using ZOOM.
1975 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1976 Commands "lang" and "charset" sets language and character set respectively.
1977 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1978 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1980 Attributes from multiple CCL fields may be OR'ed rather than merged
1981 using directive "@field or". Fields are still merged by default -
1982 equivalent to "@field merge".
1984 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1987 Fixed bug in zget for parameter ExtendedServicesResponse.
1991 --- 1.8.6 2002/03/25
1993 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1995 Client displays USR.1:SearchResult-1 (hits per term).
1997 Additional Search Info for search in Generic Frontend Server.
1999 Fixed CCL parsing of "field=s".
2001 WIN32 installer - using the excellent NSIS software from nullsoft.
2003 Fixed CCL parsing of "field = - <number>".
2005 Added function yaz_marc_decode that decodes MARC for line mode
2006 display or XML (similar to that used by JZKit).
2008 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2009 Z39.50. But ISO/ILL was, however.
2011 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2012 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2014 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2015 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2017 --- 1.8.5 2002/02/03
2019 New YAZ client features: Command completion and new commands:
2020 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2021 Code provided by Jacob Poulsen.
2023 New call oid_trav, that visits all registered OIDs via callback.
2025 Function ZOOM_record_get now returns const char pointer rather than
2026 void pointer. It saves a lot of type casts.
2028 For YAZ client, command "auth" now allows you to set authentication
2029 in IdPass style. It is enabled when three tokens are given - order
2030 is user, group and password.
2032 Fix memory leaks in MARC record handling for ZOOM.
2034 New option for YAZ client, -k <kilobytes> that sets
2035 maximum record size. Similar to -k option for generic frontend
2036 server and yaz-ztest.
2038 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2040 Prefix query parser reports "fail" when bad attribute set is given.
2042 Fix in MARC decoder. Proximity logging. Fix for attribute set
2043 in scan handler for server. Patches by Shigeru Ishida.
2045 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2048 Configure option --with-openssl=<dir> now works when a directory is
2049 specified. Patch provided by Morten Bogeskov.
2051 New option for YAZ client, -u <auth>, that sets authentication.
2053 ZOOM fix: error information was sometimes "missing", since error
2054 was cleared/reset too when it shouldn't.
2056 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2058 --- 1.8.4 2002/01/04
2060 Scan for ZOOM API. New object ZOOM_scanset. New functions
2061 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2062 ZOOM_scanset_destroy.
2064 New ZOOM function, ZOOM_connection_last_event, that returns type
2065 of last event (such as "receive data", "send data", "apdu received",
2068 New ZOOM option, schema, that specifies schema for retrieval.
2070 New CCL feature. Qualifiers can be aliases for one or more
2071 other qualifiers (if more than one is given, OR is used).
2073 ZOOM uses named result sets if target supports it.
2075 Two new YAZ client commands: . (dot, which sources a script of YAZ
2076 client commands), and ! (to execute shell command.). Implemented
2079 Working on Debian packages.
2081 --- 1.8.3 2001/11/19
2083 YAZ client enables named result sets only if target supports it.
2085 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2087 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2088 with key="host" to get same result.
2090 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2091 Function Z3950_resultset_record(s) returns references to records
2092 "owned" by resultset. To become owner use Z3950_record_clone.
2094 Function z_ext_record handles Extended Services. Thanks to
2097 --- 1.8.2 2001/11/12
2099 CCL Parser fix: ignore token comma when dealing with and-lists.
2101 Documentation updates for COMSTACK.
2103 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2104 Changed prototype Z3950_records. For some functions, int parameters
2105 were changed to size_t.
2107 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2110 New MARC decode/display function, marc_display_exl, which properly rejects
2111 non-ISO2709 records. YAZ client uses it.
2113 --- 1.8.1 2001/10/29
2115 Fix bug: local attribute set wasn't set correctly in PQF strings.
2119 * Old Z39.50 codecs no longer supported.
2121 Added ZOOM C binding. See http://zoom.z3950.org/
2123 Renamed states for COMSTACKs to avoid confusion with events.
2125 Implemented cs_look and proper cs_rcvconnect.
2127 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2129 Configure detects POSIX threads on OpenBSD.
2131 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2132 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2134 When error is returned from present handler, non-surrogate diagnostic
2135 is returned in present response (and fetch handler is no longer called).
2137 * Minor adjustments to pquery parser (PQF). Token characters may be
2138 escaped by using backslash (C-style).
2140 PQF parser allows string attribute values to be specified. For @attr,
2141 non-numeric characters after the equal-sign are treated as strings
2142 (e.g. @attr 9=title).
2144 CCL trunction character may be defined (@truncation in file)
2146 * function zget_ExtendedServicesRequest sets waitAction to
2147 waitIfPossible (was wait).
2149 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2152 CCL operator names may be set in field definition files (CCL_bibset).
2153 See ccl/bib1 for an example.
2155 Fixes in ASN.1 compiler for C++ compatibility.
2157 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2158 and "op_or" to avoid conflict with C++.
2160 Fixed problem with GNU readline detection on Redhat 7.0.
2162 Added step-size for Scan backend handler.
2164 Fixed bug that made the frontend server crash when no attribute
2165 set was specified for scan.
2167 Front-end server automatically switches to original working directory
2168 when installed as an NT service. Previously -w had to be specified to
2171 Added extended attributes for retrieval module (data1), so that data1
2172 records carry d1_readXML/SGML attributes. d1_read also supports
2173 null-data rules ( <tag/>)
2175 On UNIX when POSIX threads are available, a separate library libyazthread
2176 is created. Programmers should link with that library and the yaz library
2177 when using threads. The reason for the split was that some applications
2178 on Linux, such as Apache, doesn't work well when using shared objects that
2181 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2182 (or any frontend server) in SSL mode by specifying ssl: followed by
2183 address. Only tested on UNIX.
2185 Added feature for CCL module. Virtual structure s=al or s=ol generates
2186 and-list and or-list respectively instead of phrase search.
2190 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2191 log_mask_str. This was done to avoid name conflicts with other libraries
2192 (such as other PHP extensions).
2194 Added raw OID member for preferred record syntax (request_format_raw)
2195 and returned record syntax (output_format_raw) for backend fetch method.
2197 Config file yaz-config now accepts options so that it returns specific
2198 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2200 Shared library support for UNIX using GNU libtool.
2202 * Modified backend interface. Request/Response struct's replaced by
2203 one read/write C struct. For example bend_fetchrequest and
2204 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2205 Every handler - even search has to be registered in bend_init
2206 handler. This means that the YAZ library no longer refers to
2207 external functions and it makes it possible to make the whole
2208 thing a single DLL/SO.
2210 Added Segment handler for backend server.
2212 Added Zmbol/Zebra administrative functions to YAZ client.
2214 Threaded frontend server on UNIX (when POSIX Threads are available).
2215 Starting the server with option -T enables multi-threading.
2219 Added configure option --enable-comp/disable-comp to control use
2220 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2221 located in sub directory asn.
2223 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2224 in ${exec_prefix}/bin along with the other programs yaz-client and
2227 GNU automake used to maintain makefiles.
2229 Added several OID's.
2231 Changed retrieval module so that we can load records with no abstract
2232 syntax defined. Tagpaths in these records are fully composed of string
2235 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2239 On UNIX, the generated makefile now supports a proper 'make install'.
2240 The prefix can be set via GNU configure to set the install location
2241 (default is /usr/local).
2243 * YAZ programs client and ztest were renamed to yaz-client and
2244 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2245 locations, such as /usr/bin,/usr/local/bin,etc.
2247 * YAZ Header files were moved from include to include/yaz. YAZ Header
2248 files are referred to as include <yaz/log.h> rather than <log.h>.
2249 The YAZ include path (-I ..) is therefore the same as before. Programmers
2250 should update their #include statements or use -Ipath/include/yaz
2251 instead. The main motivation for doing this change is that YAZ header files
2252 can be installed in "standard" locations /usr/include,/usr/local/include
2253 without introducing conflicts, since ALL YAZ header files are stored
2254 in subdirectory yaz (under /usr/include for example).
2256 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2257 rather than project/workspace files. We switched because project files
2258 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2261 Changed name of logging function, logf, to yaz_log, to prevent name
2262 clash with some math-log functions. The YAZ header log.h defines logf
2263 to yaz_log (#define) so there should be no incompatibilities by this
2266 Added bend_start/bend_stop handlers for server. These handler are
2267 called on start/stop of server. For windows they are called whenever
2268 a service is started/stopped.
2270 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2271 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2272 in util/yc.tcl. The auto-generated C code structures are, in a few
2273 cases, incompatible with the old decoders. There are differences in the
2274 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2275 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2276 The preprocessor variable ASN_COMPILED is defined when the compiled
2277 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2278 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2279 wish to use the old encoders/decoders you can specify --disable-yc
2282 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2283 version so that it supports both new - and old version of DB Update
2285 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2286 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2287 change. The name parameter can be set to 0 in which no name is specified
2288 for the construction. The macros odr_implicit and odr_explicit sets name
2289 parameter to zero for the construction involved. New macros
2290 odr_implicit_tag and odr_explicit_tag are similar to the others,
2291 except that a name parameter is added. For programmers' that don't use
2292 ODR they probably only need to change the call to z_APDU and z_External.
2294 Added access control facility by interfacing the TCP wrapper library.
2295 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2296 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2297 name of the daemon and enables the access control as specified in
2298 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2300 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2301 den Dool <H.M.vdnDool@kub.nl>.
2303 Added reference ID parameter to most functions in server API - refer
2304 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2306 Changed name of ccl library to libccl.a (was ccl.a).
2308 Fixed bug in decoder for Explain (Category TargetInfo).
2310 Added support for GNU readline in client. Thanks to Jacob Poulsen
2311 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2313 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2314 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2315 IMPLEMENTATION! This change was made to the development version before
2316 the ZIG decided to retract the amendment. If any users MUST be
2317 compatible with the original Update definition, PLEASE CONTACT US, and
2318 we will include a separate definition corresponding to the old Update
2319 ES. Note that because of the change to the ASN.1 of the
2320 TaskPackageRecordStructure we cannot define a single structure that
2321 will support both versions.
2323 * Added const modifier to buffer parameter for some ODR/BER encoding
2324 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2325 completeWAIS, odr_dumpBER.
2327 Fixed bug in client.c which caused a crash when a scanResponse didn't
2328 contain positionOfTerm.
2330 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2331 * will cause an error in a client if a non-YAZ target sends both a
2332 * list of Scan entries and non-surrogate diagnostics.
2334 Retrieval module enhancements. Tag sets may be typed in the reference
2335 to it. From the .abs-file the "tagset" directive takes a third optional
2336 integer type for the tag set referenced. From a .tag-file the "include"
2337 directive takes a third optional type as well. The old "type" directive
2338 in the tag set itself is still recognized but acts as the default type
2341 Backend interface change. Individual Scan terms returned from bend_scan
2342 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2343 in include/backend.h.
2345 Retrieval module enhancements. Multiple tag sets and attribute sets may
2346 be specified in abstract syntax specs. Revised the error/warning for
2347 logging messages reported by the retrieval module when reading the
2350 Object Identifier system (oid_..) changed. The API is backwards
2351 compatible but the oid-routines now allocates new OID's when needed.
2352 Raw OID's may be specified in oid_getvalbyname.
2354 YAZ now uses GNU configure to generate Makefile(s).
2356 * Minor changes in some of the member names of DeleteResultSetRequest and
2357 DeleteResultSetResponse. See include/proto.h.
2359 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2360 and added member 'languages' in TargetInfo (which was missing).
2362 Changed the way attribute sets are handled in the retrieval
2363 module. These are now cached, just like the abstract syntaxes
2366 Changed YAZ so that it links with compiled ASN.1.
2368 Added Explain-schema definitions and mapping routines. The following
2369 Explain categories have been implemented: AttributeDetails,
2370 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2372 Fixed minor bug in Windows version of Server Library.
2374 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2376 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2378 Added EXTERNAL: UNIverse Resource Report (non-standard).
2380 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2381 ENUMERATED and SET OF.
2383 * Added 'const' to some of the char pointer arguments for the
2384 functions, data1_read_node, data1_getelementbytagname,
2385 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2388 Fixed bug in data1_insert_taggeddata - the last_child member of
2389 parent wasn't initialised.
2391 * Changed data1_read_record and data1_read_node so that the supplied
2392 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2393 doesn't refer to any parts of the "SGML"-buffer.
2395 Fixed bug in server library (Windows version of statserv_remove).
2397 * Changed code so that it compiles as C++. The type definition
2398 of Odr_fun which is a member of Odr_arm was changed. The result is,
2399 that an explicit typecast is needed for the fun pointer when
2400 using Odr_arm - as in:
2401 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2403 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2405 Implemented the new structured date and time definition as approved
2406 by the ZIG. Added schemaId element to the specificTag in Espec-1
2407 (also approved at the last ZIG). Thanks to RVDM.
2409 Added some Object identifiers (RVDM).
2411 Changed the Update Extended Service (RVDM).
2413 Added command "refid" to client which specifies referenceId for
2414 the following requests.
2416 Implemented extended service handling for server. See ztest.c
2417 for an example as well as backend.h. New handlers are registerd
2418 in the Init handler.
2420 * Changed interface for sort in server.
2422 Added new members to statserv_options_block. It allows a server
2423 to read options from another source than just the command line. Thanks
2424 to Charles Woodfield.
2426 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2427 renamed to zboolean. Some C++ compilers complained about the name.
2429 Minor changes to gils.abs. Added index 's' (sort) on title
2430 and date/time-last-modified.
2432 --- 1.4pl2 1998/1/30
2434 Fixed bug in server library regarding inetd mode (-i). This bug
2435 was introduced by release 1.4.
2437 --- 1.4pl1 1998/1/29
2439 Added sort facility in client and backend server interface.
2441 Fixed problem with dependencies in Makefile(s).
2443 Fixed bugs for encoders/decoders of extended services and
2446 Implemented sub-tree feature for schemas. Sub-trees are
2447 referenced in *.abs-files. See explain.abs for an example
2448 of the use of this feature.
2450 Modified bib1.att; local attributes for ANY didn't include
2451 ANY itself (only affects use of the retrieval module).
2453 Fixed bug in plain SGML reader in function data1_read_node:
2454 tags with prefix "var" was incorrectly interpreted as variants.
2456 Added feature "sub-schemas" to enable references to - and definitions
2457 of - group of elements.
2459 * Removed member parent from type data1_element (in data1.h).
2461 Implemented function odr_nullval() that returns the value of
2464 * Removed member num_children from data1_node (in data1.h).
2466 Made NT service interface part of the server library. The
2467 function statserv_main uses the NT service when required and
2468 calls the statserv_start / statserv_close routines.
2470 Routine zget_SearchRequest and zget_PresentRequest fills
2471 resultSetName/Id member with "default" instead of "Default".
2473 Fixed memory leak in server. Request queue member wasn't freed.
2475 Fixed nmem_exit so that memory is freed.
2479 Revised the CCL parser utility to be thread safe.
2481 Added function, oid_ent_to_oid, to replace the function
2482 oid_getoidbyent, which is not thread safe.
2484 * Added nmem_init and nmem_exit to initialize and release
2485 NMEM resources. Function nmem_init should be called once in the
2486 initial thread before NMEM/ODR is used. statserv.c and client.c
2487 have been changed accordingly. The change was necessary to make
2488 NMEM thread safe. The NMEM memory pool is shared amongst threads
2489 in a process. Unix-based applications will still work fine without
2492 Added NT Services interface for the the Z39.50 (statserv) Server.
2493 Refer to the ztest.c source on the usage.
2495 Windows 95/NT port using MSVC5.0. Project files are included in the
2498 * Defined new 'global' handle for the retrieval (data1) system. The
2499 new handled, data1_handle, describes the state of the data1 system.
2500 This handle is passed as first argument to virtually all
2501 data1 related routines. The functions data1_create and data1_destroy
2502 creates and destroys a data1 handle respectively.
2504 Added ODR encode stream member to all backend request structures
2505 init, search, scan etc. This stream should be used to allocate all
2506 memory used for the response when thread safe operation is needed.
2508 Changed the comstack utility, cs_addstr, to be thread safe. The
2509 returned hostname string returned by the function is now part the
2512 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2513 function. The cs_straddr takes a COMSTACK handle as argument, so this
2514 function must be used after cs_create and before bind/connect.
2515 This function is thread safe.
2517 Moved test server to 'ztest' directory - generic server code still
2518 in 'server' directory.
2520 Made prefix query (pquery.c) utility thread safe.
2522 Added new function modifier YAZ_EXPORT to 'export' public DLL
2523 functions when using windows (see include/yconfig.h).
2525 Added definitions to the OID database (util/oid.c) (RVDM).
2527 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2529 Added call to ccl_rpn_delete in client program.
2531 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2532 release of RPN structure.
2534 Added support for C++, headers uses extern "C" for public definitions.
2535 With input from RVDM.
2537 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2538 Thanks to Ronald van der Meer (RVDM).
2540 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2542 Added support for private extensions to the OID database
2543 (oid_setprivateoids()). Thanks to RVDM.
2545 Added optional, physical ANY (key replication)
2547 Fixed null-reference problem in GRS-1 output filter.
2549 Proximity operator added to Prefix Query Format (PQF).
2551 In test client command "base" accepts multiple databases.
2553 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2557 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2559 Smallish bug-fixes in the new encoders/decoders (explain).
2561 Bug fixed in DeleteRequest.
2563 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2565 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2567 Added SOIF syntax (using private OID for now) to retrieval module and client.
2569 Added Update extended service.
2571 Added SearchResult-1 additional info structure.
2573 Added optional CCL (ISO8777) interpreter as separate module. Available
2576 --- 1.2 1996/6/10 (1st anniversary release)
2578 Added Summary record syntax. Lightly tested.
2580 Added OPAC record syntax. Untested.
2582 Added ResourceReport service encoders/decoders. Untested.
2584 Fixed bug in z_Unit - wrong tagging on unitSystem.
2586 Fixed bug in the DiagRecs decoder.
2588 Added options for max PDU size and session timeout to frontend-server.
2590 Added documentation of query-language parsers and other supporting utilities.
2592 [frontend-server] Added Attribute set to the bend_scanrequest API.
2594 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2595 surrogate diagnostics were generated.
2597 [retrieval] Allow multiple local values for attribute.
2599 [retrieval] Allow multiple attributes per element in .abs files. index type.
2601 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2603 --- 1.1pl2 1996/4/10
2605 Minor changes, mostly specific to Zebra's requirements (retrieval)
2609 Repaired bug in frontend server when running multiple listening
2610 endpoints in dynamic mode.
2612 z_External() now won't break if a known, ASN.1 value comes encapsulated
2613 in an octet-string. The value will pass through unmodified in an Odr_oct.
2615 Added a bit of code to the demo client to decode & display
2616 ASN.1-structured records represented in the octet-aligned branch of
2617 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2619 Added z_ext_getentbyref() to the ASN module. Doc updated.
2621 * Completed the SCAN definition in the ASN module. This may break SCAN
2622 code based on older YAZ-versions at compile-time. The fix is easy -
2625 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2626 under the SCAN definition. Remember to initialize this, server-people.
2628 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2629 that this does not extend to ODR and ASN.
2631 Comstack allows insertion of established socket (primarily for
2632 inetd-operation of servers). Doc updated.
2634 Front-end server can now start from the inetd in TCP mode. Doc
2637 --- 1.0pl4 1996/1/24
2641 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2642 the rank and record number.
2644 Adjustments to the frontend server.
2646 Fixed diagnostic BER dumper. It ignored the file argument.
2650 Various changes to retrieval module.
2652 Changed the union discriminators of the protocol files from enums to
2653 ints paired with #defines.
2655 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2658 *Changed operator in the RPN structure to 'roperator', again to avoid a
2661 Fixed problems in Explain decoders/encoders.
2663 --- 1.0pl2 1995/12/6
2665 Memory bug in log module fixed.
2667 --- 1.0pl1 1995/12/5
2669 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2671 Bug in Explain DatabaseInfo module fixed.
2673 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2677 The shift to v1.0 signals that we now consider the *core* functionality
2678 of YAZ reasonably stable (the core being more or less equivalent to
2679 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2680 tested (Explain not at all - though that will happen soonish).
2682 Minor changes to code to support Windows port.
2684 Various minor changes after we're getting to use GRS-1 & co. more.
2686 Added Espec-1 format.
2688 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2689 of the protocol and it cannot be selected when encoding (maps into 'string'
2690 when decoding). Needed to talk to some servers.
2692 Demo client can request simple element set names.
2694 Added Diagnostic Format encoders/decoders.
2696 Added simple Close handling to frontend server (no hooks for resource
2697 reporting yet), and demonstration client.
2699 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2701 --- 1.0b3 1995/08/24
2703 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2704 handled incorrectly when records were requested in the searchResponse. This
2705 will only affect you if you use the frontend-server.
2707 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2708 Test-client will ask for and print GRS1. Ztest will return dummy records
2711 Added Explain encoders/decoders to the service-level API. Untested.
2713 Added Extended Services: Item Order encoders and decoders to the Service-
2714 level API. Untested. We could use a recent copy of the pertinent bits
2715 of the ILL protocol to add those bits.
2717 Added diagnostic format 1 encoders/decoders to the service-level API.
2720 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2721 odr_cons.c, which causes a more correct output.
2723 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2724 was always set to 0 when no records were requested in the searchRequest.
2726 * Added better external-handling. This shouldn't harm old code that
2727 *encodes* externals. It can break code that looks for a
2728 'single-ASN1-type' representation, since those types that are known
2729 are now decoded immediately. Look at the SUTRS sample code in
2730 seshigh.c and client.c. Documentation updated.
2732 Handling of structured records in bend_fetchresponse. Length -1 marks
2733 structured record, type is deduced from format field.
2735 --- 1.0b2 1995/06/27
2736 Fairly quick maintenance release to add SUTRS support.
2738 Fixed handling of SUTRS records in the demonstration client.
2740 * Added format field to the bend_fetchrequest and bend_fetchresponce
2741 structures of the backend API (frontend server). When the record is
2742 returned, the value of the format field is mapped to an OID. The
2743 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2744 of the record. The special value VAL_NONE in the bend_request means
2745 that no specific format was requested by the client. Documentation
2746 updated accordingly. Test server (ztest) will return a fixed dummy
2747 SUTRS record if your client requests SUTRS.
2749 Documentation updated accordingly.
2751 You can now set external libraries and RANLIB support in the top-level
2755 First public release.
