3 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
4 patch from Giannis Kosmas.
6 SRU: no longer URL encode SRU database. The URL for an SRU server is
7 a URL and such is alreeady encoded - at least when given with leading
8 http:// or https://. This reverts behavior to YAZ 3.0.50.
10 Support for new MARC XML notation TurboMARC which like MARCXML is a
11 complete representation of MARC/ISO2709.. This one, however, is more
12 compact and allows for faster processing with XSLT. TurboMARC can be
13 used in the marcdisp.h API, from the yaz-marcdump utility and from
16 yaz-ztest can be configured - via the database - to perform certain
17 delays when it performs operations search, present and single record
18 fetch. This allows testers to make yaz-ztest act as a real or even slow
19 Z39.50 server. Refer to the yaz-ztest man pages for details.
23 wrbuf_destroy allows NULL WRBUF passed to it.
25 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
27 Add ZOOM_connection_close.
29 No fixed size buffers for ZOOM shell - bug #3257.
31 tstodr: make it work on s390 platform.
33 New icu iterator-functions. The new icu_iter-functions makes it possible
34 to use ICU chains from many threads.
36 yaz-client: better syntax check for show command.
40 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
43 New simple local-file XML include facility which allows file glob-patterns.
44 Refer to yaz/xml_include.h.
46 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
49 ZOOM_record_get supports new parameter "format" which makes it format XML
52 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
53 JSONText in ECMA-262) is JSONValue, not JSONObject.
57 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
58 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
60 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
61 POSIX/Unix builds .so with major version 4.
63 Remove old LOG_-defines from log.h. They have been obsolete and
64 undefined by default for the last 5 years.
66 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
68 GFS: Remove socket (int *fd) from search_rr handler. The socket
69 descriptor ptr is a facility that allowed a search handler to supply
70 a socket which would serve as a callback - when search was complete.
71 This facility has now been in use for years.
73 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
74 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
75 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
76 returns 'const char *' rather than 'char *. The returned string is
77 read-only and should not be modified by applications. COMSTACK cs_close is
78 now a void function - it no longer returns int. No applications check for
79 the value and the implementations has always returned 0.
81 ZOOM: use size_t for scan hit counts and str size. Functions
82 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
83 occ (hit count) and len (string length) are now of type size_t pointer
84 rather than int pointer. This is to be able to represent large hit counts
85 and to also just to use the proper type for string length (strlen result).
87 New JSON parser. Refer to include/yaz/json.h .
89 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
90 Used to be int in some cases. Many wrbuf_-functions used to return an int
91 indicating some length.. These return values were never used. And so they
94 ODR: odr_malloc, odr_total now takes size_t for size.
96 clone_z_type: fix leak; occurred for encoding failures.
100 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
101 bug was introduced in 3.0.51.
103 --- 3.0.51 2009/12/02
105 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
107 tcpip comstack: fix leak for getaddrinfo.
109 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
110 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
111 Decoding of SRU "path" database is performed by private function
112 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
113 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
115 yaz-client: honor base command for SRU. Change when database setting
116 is applied for SRU and ensure it is kept when a connection is reset.
117 Change also the way errors are displayed or SRU (decoding of packages).
119 --- 3.0.50 2009/11/02
121 Add support for extra request / response data for SRU codecs and GFS.
122 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
123 for extra data response buffer and length. For the GFS, both request
124 and response data (XML) is carried in extra_args and extra_response_data
125 for the search handler. Patch by Ko van der Sloot.
127 ZOOM: For queries that cannot be converted to the specified rpnCharset,
128 ZOOM now returns a diagnostic on the client-side ('invalid query' /
129 10010). This fixes bug #2113.
131 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
132 cmdfile included a 'quit' command that would result in a memory violation.
134 --- 3.0.49 2009/10/01
136 Make a number of functions defined in xmlquery.c static. These have
137 never been declared in a public header file (yaz/xmlquery.h) and was
138 made public by mistake.
140 Improve speed of character conversions (iconv utilities). This makes
141 conversions from MARC-8 faster.
143 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
144 unless type desired is "raw". This will prevent type "xml" from
145 returning ISO2709 .. Which obviously can not be XML parsed.
147 Fix memory leak in ZOOM that would occur if option apdulog was used
148 on a re-used connection.
150 Frontend server logs HTTP requests.
152 Frontend server now sends Z39.50 close when it times out (sesssion has
153 been idle for too long). Versions 2.0.30 and earlier also sent close.
154 But due to a mistake this was disabled in all versions after that, i.e.
155 the server would just close the socket immediately.
157 yaz-client emits a better message when receiving an unrecognised
158 userInformationField.
160 Skip zero-length subfields when decoding ISO2709. This rare case happens
161 if a record has two FS characters in a sequence. Without this patch
162 there would be a reference beyond char array in using_code_len fragments
165 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
167 --- 3.0.48 2009/08/28
169 The show command offered by the zoomsh command now takes a 3d optional
170 parameter type which is what is passed to ZOOM_record. If the type
171 argument is omitted, "render" is used.
173 RPN to CQL conv may use USE string attributes (bug #2978).
175 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
177 --- 3.0.47 2009/07/08
179 Function yaz_xml2query allows a diagnostic element in the PQF XML
180 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
181 code and additional info respectively.
183 The BER BOOLEAN is now the integral type Odr_bool which still happens
184 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
185 typedef'd to Odr_int. This is still an integral 'int', but it may be
186 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
187 ASN-1 compiler as well as programs has been updated to use the new types.
189 --- 3.0.46 2009/06/08
191 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
192 only the bibliographic record was rendered. For type=opac, an OPAC
193 record is only returned if it is present.
195 iconv: small fix for encoding of advancegreek.
197 yaz-client: avoid double display of SRU/SRW records (bug #2798).
199 yaz-client: option auto_reconnect=on really reconnects.
201 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
203 server: avoid null ptr ref for for yaz_poll errors.
205 build: fix RPM build for RHEL 5.3.
207 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
209 --- 3.0.45 2009/03/31
211 Fixed bug #2709: TCP connect returns Invalid argument.
213 Fixed compilation for mingw.
215 Honor charset for raw records (ZOOM_record_get).
217 Fixed use of errno for threaded mode that was seen on Solaris 10.
219 Fixed argument passing with blanks in value for Windows Service.
221 Disable YAZ' own log rotate by default (no 1 GB limit).
222 The variable l_max_size which specifies the log file limit is set to 0
223 (DISABLED): This is due to the fact that YAZ is most often deployed using
224 logrotate. Also YAZ can not perform log rotate because of unsufficient
225 permissions (setuid).
227 --- 3.0.44 2009/02/17
229 List supported encodings in man page for yaz-iconv.
231 Fixed missing SSL libs for --libs output
233 Re-established OID record syntax application-xml. Nobody should use it
234 but we don't want to change soname because of this symbol being absent.
236 --- 3.0.42 2009/02/02
238 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
240 Added member named_result_sets for init handler struct for the GFS. This
241 allows a server to disable named result sets.
243 Removed OID record syntax application-xml.
245 Added support for rule-based transliterator for ICU wrapper of YAZ.
247 Fixed bug #1902: yaz-icu XML output.
249 Make YAZ checks Emacs friendly.
251 BITSTRING value shows value. Bug #2346.
253 ISO2709 decoding: skip control characters from indicator data.
255 Omit sort key by default in yaz-icu's output.
257 Allow combined single char options (again) for YAZ' options function.
259 Utility yaz-marcdump got option to display YAZ version (-V).
261 Allow YAZ to use ICU 3.4.
263 Added new ICU test case which illustrates removal of diacritics.
265 --- 3.0.41 2008/12/29
267 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
269 --- 3.0.40 2008/12/29
271 For configure, using option --without-xml2 also disables Libxslt/Libexslt
274 Fixed bug #2352: yaz-marcdump crashes for certain record.
276 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
278 Added support for Danmarc2 to UTF-8 conversion.
280 Added support for ISO5426 to UTF-8 conversion.
282 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
283 implementation version.
285 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
287 --- 3.0.38 2008/11/10
289 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
290 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
292 ZOOM C now interprets databaseName option for ZOOM connection as path
295 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
297 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
299 Dummy Libxml2 types no longer defined in headers of YAZ'.
301 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
304 --- 3.0.36 2008/09/26
306 Various ODR chapter fixes.
308 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
310 Added missing source for Windows compilation, mutex.c.
312 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
314 For SRU connections in ZOOM all records up to "count" are now fetched.
316 Fixed crash in generic frontend server (and yaz-ztest) which occurred
317 in Windows due to bad error handling for Libxml2.
319 Added facility for sending arbitrary records (ASN.1 any) using
320 ZOOM C's Extended service update. Patch by Sam Reynolds.
322 New options for ZOOM C's connection, logapdu which makes ZOOM log
325 --- 3.0.34 2008/06/18
327 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
329 --- 3.0.32 2008/06/12
331 Fixed memory violation that could occur when decoding UTF-8. This bug
332 was only present in 3.0.30 of YAZ.
334 --- 3.0.30 2008/06/06
336 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
337 GNU TLS is used by default (if found).
339 yaz-ztest returns OPAC records if a client asks for OPAC.
341 Improved speed of MARC-8 encoding.
343 Added support for lossy and loss-less MARC-8 encoding.
345 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
347 Added new Windows Service wrapper (sc).
349 yaz-client's itemorder command may now send a file.
351 Fixed yaz-marcdump to allow the use of NS prefix for record element.
353 Added new function yaz_log_xml_errors.
355 Allow (but warn) unknown XML attributes in MARCXML parsing.
357 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
359 The UTF-8 to MARC-8 conversion now uses a different set of characters
360 for Greek symbols. Bug #2120.
362 --- 3.0.26 2008/02/21
364 Added yaz_daemon (daemon.h).
366 Fixed bug #2068: pkg-config trouble
368 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
370 --- 3.0.24 2008/01/28
372 Document --with-xml2 option.
374 Added OPAC XML XSD (etc/opacxml.xsd).
376 Allow glob mask for name attribute in retrieval element for the
377 generic frontend server's retrieval facility.
379 Changed yaz_poll_poll to return yaz_poll_except for all returned events
380 except POLLIN/POLLOUT.
382 Fixed error handling in cs_listen. Bug #2037.
384 --- 3.0.22 2008/01/20
386 Fixed version in yaz/yaz-version.h.
388 Fixed bug #2027: Crash when closing connection.
390 Changed configure so that ICU support is only enabled if only ICU
391 and Libxml2 is available (because the ICU chain is XML based).
393 --- 3.0.20 2008/01/15
395 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
396 is built. Only this DLL depends on the ICU runtime.
398 yaz-ziffy is no longer part of YAZ. It is distributed separately by
399 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
401 Changed license of CCL module to 'Revised BSD'. After consultation with
402 remaining members of the original EUROPAGATE consortium, we are re-issuing
403 the CCL module without a separate license. The software was developed by
404 Index Data as part of a research project. The special license was included
405 to help feed usage information back to the project consortium to support
406 project evaluation. At this time, the project consortium has long-since
407 disbanded, and the majority of the original principals have retired. At the
408 same time, we have significantly modified the software during the following
409 years, to the point where very practically no original code remains. To
410 simplify re-use of the software, we have contacted those members of the
411 consortium who could be reached, and agreed to re-issue the module as a
412 proper part of the YAZ package.
414 Tcl scripts uses /usr/bin/tclsh as preferred shell.
416 CQL closer to being version 1.2 compliant. CQL also allows free-form
417 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
420 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
421 bug could make Extended services handling crash in the ZOOM layer. This
422 bug was only present in YAZ 3.0.18.
424 --- 3.0.18 2007/12/19
426 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
429 yaz-marcdump reads and writes collection wrapped records.
431 Handle OPAC for record conversion module.
433 Fixes for ICU wrapper.
435 Allow ICU libs to be controlled with --with-icu .
437 --- 3.0.16 2007/11/12
439 Added yaz_poll which is a wrapper for select/poll. When poll is available
440 and non-buggy, it is used, by yaz_poll . This allows more than 1024
441 sockets to be in use.
443 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
444 functionality through an XML based configuration (ICU chain). This system
445 is useful for search facilities such as Pazpar2 and Zebra that needs to
446 perform tokenization of indexed material. The ICU code in a separate
447 library libyaz3_icu.a.
449 Added HTTP tunnel facility for COMSTACK, bug #1752.
450 This is a facility that allows a Web proxy, such as squid, to tunnel
451 Z39.50 traffic. This facility is "transparent" to must applications
452 using YAZ. It's enabled by using pseudo transport connect: followed by
453 the proxy address, followed by command, then follwed by he regular
454 "virtual" addresss. For example,
455 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
457 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
459 --- 3.0.14 2007/09/21
461 Fixed bad memory reference in ZOOM_record - cuased by member not being
462 initialized. This was a problem only in YAZ 3.0.12.
464 Fixed bug in conversion from MARC to XML: Non-XML characters in control
465 fields were not removed.
467 Changed the way C code is generated from codetables.xml. Made a MARC-8
468 conversion trie for each characterSet section rather than codeTable.
469 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
470 of codetables.xml from Larry Dixson, LOC. Bug #1464.
472 --- 3.0.12 2007/09/12
474 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
475 from ZOOM_record_error).
477 ZOOM C function ZOOM_record_get returns record schema for type="schema".
479 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
481 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
483 Better SRW-to-Bib-1 diagnostic mapping.
485 ZOOM C and yaz-client announces SRU version 1.2 by default.
487 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
490 Fixed in yaz_sru_decode to allow other version than 1.1.
492 --- 3.0.10 2007/08/22
494 Added support for SRU scan for ZOOM.
496 Added support for the use of the older versions or Extended Service
497 Update in ZOOM. To faciliate this, an option "updateVersion" may be
498 set to the version , 1=first, 2=second, 3=third. The third version is
499 what ZOOM C has used so far. And that, obviously, is the default.
501 Added support for CCL queries in Z39.50 queries sent to the GFS (and
502 therefore in Zebra and in SimpleServer-based applications). The new
503 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
504 qualifier file used to transform incoming CCL queries into Type-1 RPN,
505 which is passed into the back-end search callback function.
507 Added support for HTTP Basic authentication in clients: the SRU/W
508 codec encodes the username/password elements of the PDU structure
509 appropriately, and these may be set using the "user" and "password"
510 options in ZOOM-C applications (the same options that are used for
511 Z39.50 authentication).
515 Fixed bug #1208: SSL appears to be broken in ZOOM.
517 Fixed bug #1206: Libxml2 include path weirdness.
519 Added oid_name_to_dotstring.
521 Allow elementSetName to be specified for ZOOM C record update.
523 Allow waitAction to be specified for ZOOM C based for Extended Services.
525 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
526 syntax OID. Bug introduced in YAZ 3 series.
528 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
532 Fixed bug #1157: yaz-client does not read .yazclientrc from current
533 directory. yaz-client now reads commands from file given by option -f
534 if specified; then tries to read .yazclientrc in current directory.
535 Failing that, it reads .yazclientrc from user's home directory.
537 Added support for correlationInfo Note and ID for Record Update via
540 Added yaz-client command querycharset which specifies character set for
541 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
542 (termListAndStartPoint).
544 Charset ISO5428:1984 is an alias for ISO5428-1984.
546 Implemented a way to perform scan in a result set using Z39.50. This
547 is achieved by attaching the result set name in the characterInfo
548 (type InternationalString) of OtherInformation in the Scan Request PDU.
549 The result set is identified in the otherinformation by the new OID:
550 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
551 This allows for scan in result set and faceted search . Zebra did some
552 of this in the APT term using attribute type 8 and value being result
553 set. Using the OtherInformation approach for this is cleaner and easier
554 to work with in proxies and the like. This facility can be used in
555 yaz-client using new command setscan which takes a result set as first
556 argument, start position (APT) as second.
558 Changed decoding of SRU XML packed records to deal with servers that
559 have recordData with XML data with multiple root nodes. Also make
560 comparison for recordPacking case insensitive. Again, one server
561 returns "XML" where others return "xml".
563 For SRU responses allow Content-Type application/xml as well as text/xml.
567 Fixed bug in character set conversion of BER strings. Bug introduced
572 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
574 For OID class, use oid_class consistently.
576 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
579 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
580 character set for bibliographic information interchange". By Giannis Kosmas.
582 Added documentation on new OID API.
586 Changes to generic frontend server interface: added new member
587 'query_charset' for bend_initrequest structure. A backend init handler
588 should set this member to its native character set for query terms.
589 When defined, the frontend server logic will announce this character set
590 to a client if the negotiationModel bit is set by the client. All server
591 implementors are encouraged to specify this. If a backend server does not
592 specify this a warning is issued using yaz_log(YLOG_WARN,..).
594 Added CCL utility to remove terms (stop words) from resulting RPN
595 tree. This is handled by functions with prefix ccl_stop_words_ .
597 New ZOOM C option, "rpnCharset", which allows client-side conversion of
598 terms in RPN queries.
600 Clean-up the CCL API. Moved some internal structures from ccl.h to
601 private header cclp.h. Changed ccl_parser_create so that a Bibset must
602 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
603 This is replaced by ccl_parser_find_str which takes a string instead.
605 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
606 libyaz.la is the core of YAZ except the generic frontend server and
607 does not depend on POSIX threads anymore. libyaz_server.la is the
608 generic frontend server facilities and uses POSIX thread functionality
609 if available. The libyaz.la no longer depends on POSIX threads because
610 the number of global structures is limited. NMEM no longer re-uses blocks
611 between threads ; it simply free's memory immediately but allocates in
612 "large" chunks as usual. We don't expect any performance penalties
613 because of this. The yaz_log system is still using a global log_level so
614 caution must be taken when modifying it with yaz_log_init_.. +
615 yaz_log_mask_str. This, however, should not cause any trouble because
616 these functions are called during initialization of application code
617 anyway. `yaz-config --libs server` returns libs for server applications;
618 `yaz-config --libs` returns libs for non-server applications.
620 New OID database - with public definitions in oid_db.h. Removed old OID
621 database including the head oid.h and definitions such as enum oid_value
622 and struct oident. The new OID database uses the same string names as
623 before but the 'protocol' is gone. There are now only two representations
624 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
625 converts from string to OID; functions with prefix yaz_oid_to_string
626 converts the other way.
628 Change to emit_term() in CQL-to-PQF query translation: when a term has
629 the /regexp relation modifier, do not process it for leading and
630 trailing "^" and "*", which have quite different meanings in regular
633 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
634 write handlers no longer carries a 'last' parameter. This will make
635 yaz_iconv flush "less" characters. A flush is performed by call to
636 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
638 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
639 removed, because function yaz_query_to_wrbuf does the same.
641 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
642 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
644 Deprecated MARC utility functions removed.
646 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
649 Branch split: YAZ_2_1_55_branch
651 --- 2.1.54 2007/03/16
653 Fix to ZOOM-C so that transparent reconnection is properly handled on
654 connections that are in asynchronous mode.
656 Fixed compilation on OpenBSD 4.0.
658 Large strings in GRS-1 records are now properly displayed in yaz-client.
660 Added character conversion support for "advancegreek"; based on patch from
663 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
664 sequence is met. Before the error was not set so it would be unknown.
666 Adjust yaz-marcdump MARC reader so that it skips until record separator
669 --- 2.1.52 2007/03/07
671 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
672 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
673 fd_set structure used as a bitmask for the FDs to be selected on.
675 Using ACX_PTHREAD macro to check for POSIX threads.
677 Fixed have-vsnprintf check.
679 --- 2.1.50 2007/02/23
681 Fixes for configure on BSD. Bug #900.
683 Added snprintf/vsnprintf wrappers for systems that don't have
684 limits (heavens forbid).
686 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
687 created before all previous tasks were completed and removed from the
688 task queue, the new task could be removed by a mistake.
690 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
692 Implemented pass-through CQL-to-PQF conversions. Bug #861.
694 Fixed bug #832: Problem with MARC/charset in yaz-client.
696 Fixed bug #668: save command line history for yaz-client.
698 Fixed bug #830: pkg-config support.
700 --- 2.1.48 2007/01/23
702 Extended ZOOM result set options with two options that may be read by
703 a client: resultSetStatus and presentStatus with values as specified for
705 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
707 Fixed bug #827: Using SSL fails on Debian etch.
709 Fixed bug #826: Weird looking chars for set of MARC records.
711 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
712 that is treated as an ItemOrder with itemRequest being an XML document
713 external. The value of "doc" is the content.
715 Extended the GFS search facility. New member of bend_search_rr
716 'estimated_hit_count' signals that hits is known to be an estmate
717 (higher or lower than real hit count). New member 'partial_resultset'
718 signals that the search was partial (hit count is lower or equal than
719 real hit count). For Z39.50, the information is stored in resultSetStatus
720 member of SearchResponse APDU. For SRU, the information is signalled
721 via SRU diagnostic 59: "Result set created with valid partial results
724 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
726 --- 2.1.46 2007/01/13
728 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
730 Added ZOOM_connection_peek_event.
732 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
733 the following new functions:
734 ZOOM_event_nonblock, ZOOM_connection_process,
735 ZOOM_connection_get_{socket,mask,timeout},
736 ZOOM_connection_fire_event_{timeout,socket}.
737 The existing blocking event handler, ZOOM_event, is a wrapper for the
738 + blocking ZOOM_event_sys_{poll,select}.
740 Implemented function ccl_xml_config which parses XML version of CCL
741 configuration (bug #798).
743 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
745 Added timings utility (yaz/timing.h)
747 --- 2.1.44 2007/01/03
749 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
752 Fixed bug #779: Rotation of apdu.log fails.
754 Fixed for character set conversions:
755 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
756 Honor G1 set in MARC-8 decoding.
758 --- 2.1.42 2006/12/17
760 Fixed bug #775: char conversion does not handle Alternative UTF-8
763 Implemented function yaz_marc_read_line which parses MARC line format
764 records. There is a wealth of formats out there. So far, this function
765 reads line records produced by yaz_marc_write_line.
767 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
768 more generic and easier to remember(!) options: -i format and -o format
769 which specifies input format and output format respectively - where
770 format is one of "marc", "marcxml", "line", "marcxchange".
772 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
773 does not print anything except warnings for records.
775 For yaz-marcdump, added support for MARC split into files (-s) with a given
778 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
779 spec, at http://www.loc.gov/standards/sru/record-update/
780 This has changed the binary layout of the following structs:
781 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
782 bend_update_rr . Patch by Ko van der Sloot.
784 Added GFS utility function bend_assoc_is_alive which returns 1 if
785 association is still alive (client is connected); 0 otherwise (client
786 closed connection). This allows busy servers to stop working for
789 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
790 been a separate piece of software. This version of ziffy has been modified
791 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
793 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
795 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
796 Client code may now interrogate options such as "init_opt_sort" to
797 find out whether the server claims to support various options.
799 --- 2.1.40 2006/11/27
801 Added utilities yaz_{set,get}_esn to set/get element set name from
804 Removed the build of libyazthread.la. The libyaz.so is the threaded version
805 of YAZ and has been so since YAZ 2.1.10.
807 Implemented ZOOM_record_error which returns error information for
808 record (surrogate diagnostic).
810 --- 2.1.38 2006/10/31
812 Updates for SRU Update by Ko van der Sloot:
813 1. Changed name from "operation" to "action"
814 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
815 versions in the code, marked as 'backward compatible'.
816 3. Added diagnostics for SRU Update.
818 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
820 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
822 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
824 For GFS, fixed problem with SRU diagnostic 'First record position out of
825 range' being issued for 0 hits.
827 zoomtst10 part of Windows Build.
829 --- 2.1.36 2006/10/13
831 Implemented yaz_filepath_comp which splits a path into file path
832 components (required by Zebra 2.0.3+).
834 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
835 BSD inspired license until now so this should not have any real impact on
836 anybody. See http://www.opensource.org/licenses/bsd-license.php
838 Fixed bug #687: Missing log lines.
840 Fixed bug #678: CQL to PQF translation does not preserve double-quote
843 Fixed bug #689: SRU diagnostics to be added.
845 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
846 whether a connection is idle (no more work do do).
848 --- 2.1.34 2006/10/04
850 Change type of optval from long to int for invocation of setsockopt with
851 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
853 Added support for specifying the max log file size for the Generic
854 Frontend Server. The size is given with option -r.
856 --- 2.1.32 2006/09/21
858 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
860 --- 2.1.30 2006/09/17
862 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
865 Fixed bug in Generic Frontend Server that could cause a server to stop
866 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
868 For the generic frontend server, the maximum record size is used as maximum
869 size of incoming packages (SRU + Z39.50). The value until was previously
870 only used in Z39.50 Init negotiation and, later, in a session controlled
871 sizes of records returned. This is controlled using -k option. It can be
872 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
874 --- 2.1.28 2006/09/04
876 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
879 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
881 New option for yaz-marcdump -lpos=value which allows setting a portion
882 of MARC header to a certain value.
884 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
886 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
887 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
889 --- 2.1.26 2006/08/15
891 Fixed problem with SRU mode type (soap, get, post) for yaz-client
894 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
896 --- 2.1.24 2006/08/08
898 Fixed MARC ISO2709 encoding routines to deal with character set
901 Minor changes to GFS logging. Database included in search request log
904 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
905 cached/multiple records.
907 Shared libraries are built by default on Unix+configure.
909 Changed cql2pqf transformation to use a different evaluation order. The
910 new order is: always, relation, structure, position, truncation, index
911 and relationModifier. Old order was: always, relation, relationModifier,
912 structure, index, position, truncation. Note that the the latter ones
913 override former ones for identical attributes.. The new scheme means that
914 it is possible to override any existing attribute with a relationModifier.
915 And also that it is possible to override everything for the index rule
916 (except the ones listed in relationModifier). No order is perfect but this
917 one, we believe, covers more real cases.. The "always" should have been
918 called "default", since the attributes there can be overridden with all
921 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
922 compilation phase, but also for yaz-config --cflags output. This allows
923 us to have public headers with Libxml2 stuff in them . It should also,
924 eventually, make Libxml2 checks redundant in packages using YAZ, such
927 --- 2.1.22 2006/06/15
929 Changed SRU update structure bend_update_rr so that SRU diagnostics are
930 stored in uri, message and details.. Previously diagnostics were stored
931 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
932 compatibility.. but he's probably the only one affected, so.
934 Added support for CCL, compiled on the client side, in ZOOM-C. This
935 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
936 input; the resulting query objects can be used for for searching with
937 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
939 YAZ' configure searches for OpenSSL by default.
941 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
942 SL_CTX_use_certificate_file. See
943 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
944 for more info. Thanks to Ko van der Sloot.
946 --- 2.1.20 2006/06/02
948 Bug #600: SRU GET, POST support for yaz-client. Introduced
949 command 'sru' which selects method SOAP/GET/POST.
951 Allow missingValueAction to be specified for the sortspec string -
952 function yaz_sort_spec. By default, the missing value action is null.
953 Use ! to specify "abort". Use = followed by stringvalue to specify default
956 Ensured that Present-handler (if defined) is called in GFS before any call to
957 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
958 searchRetrieve requests.
960 Documentation for YAZ is now based on the Docbook XML/XSLT using
961 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
962 is no longer depending on jade/openjade or docbook-to-man scripts.
963 PDF is no longer part of the distribution - but can optionally be
964 made using DSSSL/jadetex or FOP.
966 Added retrieval handling support in Generic Frontend Server to support
967 conversion between MARC/XML as well as XSLTtransforms. See
968 etc/yazgfs.xml for an example.
970 Added Authentication support to Generic Frontend Server in SRU
971 mode. Authentication using HTTP Basic is supported, as is the use
972 of 'x-username' and 'x-password' parameters in the request itself.
974 Added support for a new character set MARC8s identical to MARC8 except
975 that it converts combined characters to single Unicode characters in the
976 Latin-1 range (when possible).
978 --- 2.1.18 2006/04/24
980 ASN.1 compiler 0.4: generates brief Doxygen file header for
981 generated .h/.c files.
983 Utility yaz_iconv now supports conversion to MARC-8.
985 New facilities for the MARC module. The reading - and writing of
986 content are separate methods for the yaz_marc_t handle. The following
987 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
988 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
989 format). Write functions have prefix yaz_marc_write_.. The existing
990 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
991 available. Removed support for OAI-MARC and simplexml (not the
992 simplexml from PHP5).
994 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
995 to be returned for this connection.
997 --- 2.1.16 2006/03/31
999 Allow multiple languages and charsets to be specified with
1000 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1001 negcharset iso-8859-1,utf-8
1003 Translation of proximity nodes from CQL into PQF now works.
1005 Moved to automake 1.8, 1.9.
1007 Added function yaz_log_set_handler which allows a log handler to be
1008 installed. This handler will be called for all log messages. Output
1009 to file is also produced; but that can be disabled by passing NULL
1010 fname to yaz_log_init_file.
1012 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1014 For SRW (including GFS), accept application/soap+xml as content-type
1017 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1018 produces NO stylesheet reference even if a default stylesheet is specified
1021 --- 2.1.14 2006/03/14
1023 Updated Windows package to include yazd.dll + yazd.lib for the
1024 Development component.
1026 If the environment variable YAZ_LOG is set, then it is used as a
1027 string indicating the default level of logging to use if not
1028 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1029 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1030 used as before. So, for example, to omit warnings from YAZ logging,
1031 export YAZ_LOG=-warn
1033 cql_transform() now map structure and other attributes before indexes,
1034 so that index-specific structures and other attributes can override
1035 defaults. So now a combination of mapping specifications such as:
1037 index.dc.date = 1=date-modified 4=5
1038 does the right thing.
1040 cql_transform() now also respects the "always" mapping specification,
1041 which establishes an initial set of attributes to be used for all
1042 terms except where overridden by more specific attributes associated
1043 with the index, relation or modifier.
1045 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1046 which mode to use; one of "post", "get" or "soap" (SRW, default).
1048 Fixes for yaz_iconv routines: changed trie-based character set conversions
1049 to use only non-negative values for bit fields due to Sun's C compiler not
1050 supporting negative values.
1052 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1053 sequences where not read correctly. Fix by Rustam Usmanov.
1055 Updated win/makefile to use options, settings which makes things
1056 compile with VS C 2005.
1058 --- 2.1.12 2006/02/01
1060 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1062 In ZOOM socket code, use select instead of poll on MacOSX.
1064 ZOOM-C now support client-side compilation of CQL into RPN that is
1065 sent to the server, enabling CQL to be used against all Z39.50
1066 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1067 ZOOM_query object, and submit it using ZOOM_connection_search().
1068 The CQL-to-RPN translation uses a configuration file, the name of
1069 which must be specified in the Connection's "cqlfile" option.
1071 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1072 function, which takes as its start-term parameter a ZOOM_query object
1073 (which may have had either CQL or RPN set into it).
1076 --- 2.1.10 2005/11/29
1078 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1079 GFS to support this as well. Backend handler, bend_srw_update, does the
1080 update work. Code contributed by Ko van der Sloot.
1082 Allow retrieval of Search Result-1 information in ZOOM by the use of
1083 options that are attached to a result set. ZOOM documentation updated
1086 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1087 UTF-8 conversion. Patch by Raj Patel.
1089 Added option -m to GFS to control formatting of timestamps in log file.
1091 Added 'exit' as synonym for 'quit' in yaz-client
1093 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1094 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1095 for the new members. Patch by Ko van der Sloot.
1097 Added support for SRU POST. It is supported for content-type
1098 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1100 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1101 Instead make the library libyaz.la multi-threaded. Threading as a whole
1102 can still be disabled by configure option --disable-threads. Previosly,
1103 with older GLIBCs there were problems with MT libs under Apache. This
1104 has now been fixed a long time ago.
1106 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1109 CQL module modified to be case insensitive for relations/indexes/operations.
1111 Fixed bug in CQL transform code: incorrect value relationModifieder
1114 Added 'show all' command for yaz-client which retrieves all results
1117 Added new yaz-client, xmles, which takes a (private) OID and
1118 a document to be sent as an extended service request.
1120 Describe new yaz-client commands wait_response and set_auto_wait.
1122 Increase TCP/IP listener backlog from 3 (which I am guessing was
1123 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1124 that the socket will queue as many incoming connections as it's able
1125 to handle ongoing connections. In other words, it will never now
1126 refuse a connection that it would be able to handle merely because
1127 it's not got around to accepting() enough of the pending connections
1128 yet. This is the behaviour anyway under Linux, where the listen()
1129 argument is ignored; but not under BSD and on systems such as
1130 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1131 YAZ-based servers should now be uniform across operating systems in
1134 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1135 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1136 This allows yaz-marcdump to read large MARC batches (>2 GB).
1138 Modified all YAZ source files - except the source which is auto-generated
1139 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1142 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1143 corresponding to the existing *_setl() function. These allow option
1144 values containing arbitrary valuues.
1146 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1147 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1148 except that it returns an indicator of whether or not the sort
1149 criterion was accepted (0 for OK, -1 for invalid).
1151 --- 2.1.8 2005/06/07
1153 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1154 MARC output rather than returning "new" buffer.
1156 yaz-client warns about unknown init options.
1158 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1160 --- 2.1.6 2005/05/24
1162 Added support for SRW sort in Generic Frontend Server. Patch
1163 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1164 sortKeys - or NULL if none is provided.
1166 Fixed bug #307: It was impossible to specify indefinite/no timeout
1167 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1170 Added support for multiple languages and charsets to be specified in
1171 ZOOM. Each charset/language is separated by a blank. If negotiation is
1172 in effect in init-response, Option
1173 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1174 Code based on patch by Vasiliy Osadchuk.
1176 Fixed bug #306: infinite recursion that occurred when calling
1177 yaz_log_level_init as the first call (before other log level or
1180 Fixed bug in scan handling in front end server: if preferred-Position-In-
1181 Response was non-present, a NULL pointer referece was performed.
1183 --- 2.1.4 2005/04/26
1185 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1186 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1187 now defined for all those error codes. So instead of putting 109 in
1188 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1189 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1191 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1194 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1196 Program yaz-client now exits and produces an error message if multiple
1197 Z39.50 servers are specified on the command line (none or one allowed
1200 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1203 --- 2.1.2 2005/03/16
1205 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1207 Fixed bug #272: Preserve spacing for CCL terms.
1209 --- 2.1.0 2005/03/14
1211 Added support for virtual hosts and multiple backend servers for
1212 the YAZ frontend server. The configution is XML based and
1213 support specificition of CQL to RPN mappings and explain information.
1214 See section "Virtual Hosts" in the YAZ manual.
1216 Extended OPAC display utility. OPAC display utility renders
1217 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1218 to supplement yaz_marc_decode_wrbuf.
1220 Fixed a bug in MARC decoder that could caused it to crash for some
1221 invalid MARC records. More diagnostics and warnings where added in
1222 XML output (warnings, etc are stored in comments).
1224 --- 2.0.34 2005/02/08
1226 Fixes for UNIX domain sockets. Bug #261.
1228 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1230 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1231 Added yaz_marc_subfield_str which defines subfield lead string which is
1232 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1233 yaz_marc_endline_str which defines end of fields string used in
1234 YAZ_MARC_LINE format. Default string is newline.
1236 Experimental support for MarcXChange. This format can be produced
1237 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1238 http://www.bs.dk/standards/MarcXchange.xsd
1240 Added yaz-client commands scansize that sets maximum number of
1241 entries to be returned by scan.
1243 --- 2.0.32 2005/01/11
1245 Added support for SRW scan in yaz-client and Generic Frontend Server.
1247 * Added whereInList member to SRW Scan Term.
1249 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1251 Fixed NMEM system to return aligned blocks on the smallest boundaries
1252 that are suitably aligned for all possible types on the particular
1253 architecture YAZ is being built for.
1255 --- 2.0.30 2005/01/04
1257 Fixed numerious warnings that was issued with newer versions of GCC.
1259 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1260 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1263 Make YAZ Generic Frontend Server slightly faster.
1265 Enhance (and reduce) logging for Generic Frontend Server.
1267 Revert YAZ log system so that it flushes every write operation
1268 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1270 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1271 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1272 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1273 will effectively disable old definitions.
1275 --- 2.0.28 2004/11/09
1277 Added yaz_log_time_format which specifies log format using
1280 Added yaz_log_module_level which returns mask for a module. Value
1281 is non-zero mask a if module is enabled; zero if disabled.
1283 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1284 in include/yaz/cql.h.
1286 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1288 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1290 Fixed bug #172: RPM builds does not enable SSL.
1292 Doxyfile.in part of dist. Doxyfile generated by configure.
1294 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1295 are given and the corresponding component does not exist.
1297 Extend CCL documentation in YAZ reference. Describe r=r.
1299 --- 2.0.26 2004/10/01
1301 Fixed MARC->MARCXML conversion to properly deal with
1302 fields, subfields, indicators having non-ASCII characters.
1304 Fixed MARC->MARCXML conversion so that ASCII control characters
1305 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1308 Added YAZ GFS support for conversion from Z39.50 surrogate
1309 diagnostics to SRW surrogate diagnostics.
1311 Bug fix: YAZ GFS did not return schema in explainResponse.
1313 --- 2.0.25 2004/09/30
1315 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1316 now converts recordSchema to elementSetName as well as schema URI.
1318 Fixed bug in COMSTACK that prevented HTTP request packages from being
1321 --- 2.0.24 2004/09/29
1323 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1324 does not require white-space before and after the dash in a range, e.g.
1325 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1328 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1329 due to new GCC removing "redundant" code.
1331 Added yaz-client commands scanpos and scanstep that sets preferred
1332 position and step-size for scan.
1334 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1336 Added CCL utility ccl_qual_buf which parses one or more CCL
1337 spec lines in a buffer.
1339 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1340 of name and value - ignoring empty lines and comments.
1342 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1344 Added odr_get_element_path which returns current element path for an
1345 ODR handle. This utility is useful in error handling or user-defined
1348 Added ODR_PRINT utility odr_set_stream which is is a more generic
1349 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1350 to a write function and pointer to close function. The close function - if
1351 non-NULL - will be called during odr_destroy.
1353 Fixed bug in CCL parser where truncation char was not removed from
1354 right side when truncation=both was in effect.
1356 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1359 --- 2.0.23 2004/08/11
1361 Fix buffer overrun in CQL parser when dealing with proximity (%).
1363 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1364 to UTF-8/UCS conversion is now only based on codetables.xml.
1366 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1368 --- 2.0.22 2004/08/06
1370 Add support for more "commit changes" in ZOOM (uses Extended Services).
1372 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1375 Yet another small fix for configure of SSL.
1377 --- 2.0.21 2004/05/14
1379 Fix SSL libs for configure when --with-openssl=DIR is given.
1381 --- 2.0.20 2004/05/10
1383 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1385 SSL comstack now uses yaz.pem certificate file on server side
1386 by default. Certificate filename can be configured by calling
1387 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1389 Fix bug regarding multiple calls to ZOOM_connection_connect.
1391 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1393 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1394 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1396 ZOOM now allows inspection of X509 peer certificate for verification.
1397 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1399 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1400 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1401 as "modular" but it simplifies things.
1403 Added cs_get_peer_certificate to that returns peer X509 PEM.
1405 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1406 NULL if SSL is unavailable.
1408 Documentation about MARC decoding tools.
1410 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1412 --- 2.0.19 2004/03/30
1414 Rename CHANGELOG to NEWS to follow GNU style packing.
1416 Fix bug with missing initialization of member in init_diagnostics.
1417 This bug affects threaded version of GFS server.
1419 --- 2.0.18 2004/03/20
1421 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1424 Ensure zlib.dll is packed with Windows install.
1426 --- 2.0.17 2004/03/17
1428 Fix encoding of xsd:string to use text instead of CDATA.
1430 Fix endless loop in CQL parser with unbalanced ".
1432 Use a more compact way to store MARC-8 conversion tables.
1434 --- 2.0.16 2004/03/16 Debian only
1436 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1439 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1444 --- 2.0.15 2004/03/01
1446 Another fix for decoding of XML packed records.
1448 --- 2.0.14 2004/02/25
1450 Fixes for Chunked encoding. White space not ignored after length spec.
1452 Update NS and use default NS for SRW diagnostic elements.
1454 --- 2.0.13 2004/02/23
1456 Implement ZOOM_resultset_cache_reset which resets record cache.
1458 Implement ZOOM_resultset_sort which sorts a result set.
1460 Implement chunked HTTP transfer.
1462 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1464 --- 2.0.12 2004/02/16
1466 Added member 'schema' to bend_explain_rr structure so that backend
1467 can specify explain record identifier. Defaults to Zeerex 2.0.
1469 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1471 --- 2.0.11 2004/02/16
1473 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1476 Added init command for yaz-client which sends "extra" init request.
1478 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1479 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1481 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1483 Make ZOOM error code for "invalid query".
1485 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1487 --- 2.0.10 2004/02/05
1489 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1492 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1494 Added option -p <file> to make Generic Frontend Server to write PID file.
1496 Added option -D to put Generic Frontend Server in background on its own.
1498 Make ZOOM C recognize option "password". If unset, "pass" is used
1499 (for backwards compatibility).
1501 Fixed a bug in Generic Frontend Server that could make it crash if a
1502 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1505 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1506 Must be issued before open, in order to be in effect.
1508 --- 2.0.9-6 2004/01/12 Debian/Windows
1510 Make the SRU server more picky WRT unknown params, etc.
1512 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1514 New YAZ client command, options, that sets Z39.50 options.
1516 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1517 options from a string of tokens (one token for each option bit).
1519 Update SRW diagnostic code messages.
1521 --- 2.0.9-5 2004/01/07 Debian/Windows
1523 Handle user defined stylesheet for SRW/SRU.
1525 --- 2.0.9-4 2004/01/06 Debian/Windows
1527 Fix bug in decoding of Content-Length.
1529 --- 2.0.9-3 2004/01/06 Debian/Windows
1531 Fix a bug with decoding of XML packed records.
1533 --- 2.0.9-2 2004/01/05 Debian only
1535 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1537 Fix bug in SRW/SRU diagnostics decoding.
1539 --- 2.0.9 2004/01/05
1541 Fixed bug in Generic Frontend Server which could drop records exceeding
1542 preferred message size. Reported and fixed by Irina Dijour.
1544 Fixed calculation of package size for structured records in Generic
1545 Frontend Server. Reported and fixed by Irina Dijour.
1547 Fixed namespace for SRW/SRU diagnostics.
1549 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1551 --- 2.0.8 2003/12/22
1553 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1554 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1557 CQL changes to reflect recent changes to the specification:
1558 * Documentation talks about context sets instead of index sets.
1559 * Documentation talks about indexes instead of qualifiers.
1560 * The CQL-to-PQF transformer's configuration file now uses
1561 "index.set.name = <attributes>" instead of the old form
1562 "qualifier.set.name = <attributes>". (Both forms are still
1563 understood but the latter is deprecated.)
1564 * CQL terms with no explicit index specified are now interpreted as
1565 cql.serverChoice instead of srw.serverChoice (which of course
1566 behaves exactly the same.)
1568 --- 2.0.7 2003/12/16
1570 MARC conversion can now generate ISO2709 output in another
1571 character set. yaz-marcdump uses this facility if you invoke it
1574 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1575 functions from there can be used from C++.
1577 --- 2.0.6 2003/12/04
1579 Frontend server now transfers memory from decoded packages to stream
1582 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1583 references to show up.
1585 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1586 the ZOOM Abstract API. The older names for the same options are still
1587 also supported for the benefit of old applications.
1589 ZOOM-C supports "implementationId" and "implementationVersion" options
1590 to go along with "implementationName". These allow the user code to
1591 specify identification strings to be sent to servers.
1592 Add OID for the new ExtLite attribute set.
1594 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1595 as requested/supplid by Ere Maijala <ere@atp.fi>
1597 For generic frontend server, reverse the order of
1598 "toolkit-supplied / application-supplied" strings sent as implementationId,
1599 Name and Version. Also, remove the spaces around the slash. This brings
1600 the GFS in line with the behaviour of ZOOM-C on the client side.
1602 Add function ZOOM_scanset_display_term.
1604 yaz-client shows scan displayTerm if present.
1606 Utility yaz-iconv is now installed by default along with the man page
1609 Extend configure check for OpenSSL to use pkg-config where available (such
1612 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1613 server to specify uid/gid/mask for socket using the format
1614 unix:[user=uid,][group=gid,][umask=mask,]file=path
1615 If file= is omitted the existing format is assumed, e.g.
1617 in which case the mask is 0666 (rw for everybody).
1619 Major restructure of YAZ source. All source in libyaz is in src directory.
1620 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1621 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1623 Added man page for utility yaz-marcdump (used to be called marcdump).
1624 yaz-marcdump is installed by 'make install'.
1626 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1627 of incoming package failed.
1629 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1631 Change prototype of odr_perror: add const to message string.
1633 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1635 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1636 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1637 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1638 DNS lookup. There should not be any compatibility problems with this
1639 assuming that blocking=1 or 0 is used.
1641 Fix bad reference in UNIX comstack in function cs_addrstr.
1643 Fix for compilation on AIX.
1645 The generic front-end server (server/seshigh.c) now supports returning
1646 Init diagnostics to the client in User-information-field, in
1647 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1650 --- 2.0.4 2003/09/04
1652 Allow any CQL relation (not just all,any,exact,scr).
1654 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1655 that features the same UI.
1657 Implemented command update0 in YAZ client which is equivalent to
1658 update but uses old of Ext Update ASN.1.
1660 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1661 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1662 Previously no OID was used for this info.
1664 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1665 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1666 returns 'malformed search term' otherwise.
1668 SortResponse member resultCount now set to NULL in sort handler of
1671 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1674 Add three new utility functions for translating OIDs between various
1675 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1676 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1677 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1678 char *oid_to_dotstring(const int *oid, char *oidbuf);
1679 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1681 Reverted modifications for ES Update definition for z_IU0Update
1682 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1683 is back to YAZ 2.0.2.
1685 String value attributes for CCL parser.
1687 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1688 which their FirstSearch server returns in Init responses, sometimes
1689 carrying useful diagnostic information when Init fails. This has the
1690 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1691 "z39.50/oclcui.asn", where its definition is somewhat different from
1692 what OCLC document on their web-site, as required to interoperate with
1695 Support for anonymous authentication in yaz-client. Use the command
1698 * Fix the OID of the Index Data-local "admin" Extended Service from
1699 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1700 the 1000, which indicates a locally-defined OID, was a mistake.
1702 --- 2.0.3 2003/06/20
1704 Fix CCL directive @case handling so that it affects string match for
1705 both CCL keywords and qualifiers.
1707 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1708 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1709 Decoder has been updated with ASN.1 changes as listed in
1710 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1711 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1712 z_IUUpdate, remains unchanged.
1714 ZOOM_record_get may now return a record in a specific character set.
1715 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1716 "from" is the character set of record as returned by target. "to" is
1717 the character set to be returned. If omitted, "to" is UTF-8.
1719 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1721 New ODR utility, odr_getelement, which returns name of element for
1722 which encoding/decoding failed.
1724 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1725 in cases where a required element was omitted.
1727 Bug fix: some MARC8 sequences were not converted.
1729 New ZOOM option "step" which specifies number of records to be
1730 retrieved in one chunk. Used in conjunction with "start" and "count".
1732 SRW support for yaz-client. Use scheme http: to use it, e.g.
1735 yaz-client no longer does (un)intelligent character set conversions
1736 by default. Can be enabled with charset and marc_charset commands.
1738 xmalloc trace fix for 64-bit systems such as DEC alpha.
1740 Solaris 2.6 compile fix.
1742 New function, cql_strerror() translates SRW error codes, as returned
1743 by cql_transform_error(), into human-readable English strings. Used
1744 in yaz-client diagnostics when appropriate.
1746 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1747 converts it into a type-1 query which is sent to the server. This
1748 makes CQL available for use with all Z-servers, as opposed to the tiny
1749 minority that can handle CQL queries themselves.
1751 --- 2.0.2 2003/04/28
1753 New Debian package layout similar to the Redhat Package layout.
1755 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1756 and search result respectively.
1758 --- 2.0.1 2003/04/25
1760 Redhat package is now several packages: libyaz (runtime libraries),
1761 libyaz-devel (development and documentation, and yaz (utility programs).
1762 Package spec file by Morten Bogeskov.
1764 New member 'schema' in struct bend_fetch_rr which the name of requested
1765 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1766 handler MAY set this to reflect the schema of the returned record.
1768 New member 'display_term' in struct scan_entry. GFS now sets member entries
1769 and allocates scan entries to be filled by user scan handler. In previous
1770 version, entries member was allocated by the scan handler. That still works,
1771 but the GFS will ignore member display_term - assuming it was NOT set by
1772 the handler. The fact that the GFS now allocates the entries both allows
1773 for new members and makes a scan handler easier to write.
1775 Fix CQL lex buffer overflow.
1777 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1778 SRU default recordPacking is string.
1780 SRU protocol support for frontend server.
1782 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1784 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1786 Added scan for the ZOOM shell (zoomsh).
1790 * String Identifers for Schemas (Amendment 5).
1791 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1792 Old definition for schema
1793 Odr_oid *schema; /* OPT */
1798 Z_InternationalString *uri;
1799 #define Z_Schema_oid 1
1800 #define Z_Schema_uri 2
1803 * resultCount parameter to Sort Response (Amendment 1).
1804 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1806 Support for SRW 1.0 over HTTP. This is an optional feature and
1807 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1810 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1811 on the same port. SRW SearchRetrieveRequests are mapped
1812 to bend_init,bend_search,bend_fetch,bend_close.
1814 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1816 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1817 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1819 ZOOM connections are SRW based if schem http is used for hostname
1820 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1821 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1823 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1824 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1825 distance=n, order=true/false, relation=le, prox unit=word. If
1826 n is omitted, distance 1 is used.
1828 Fixed problem with C compiler include path in wrong order.
1830 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1831 on Solaris. Patch from Ko van der Sloot.
1833 New MARC decode API. All new functions operate on a yaz_marc_t
1834 handle. The most important new functions are: yaz_marc_create,
1835 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1836 decode and destroy respectively. Decoder can produce formats
1837 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1838 include/yaz/marcdisp.h.
1840 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1841 to UTF-8, UCS-32, wchar_t or Latin-1.
1843 * Prototypes for yaz_iconv_-functions moved to separate header
1844 include/yaz/yaz-iconv.h.
1846 Make a few private functions 'static' in unix.c. This prevents
1847 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1849 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1850 are set when Init Response is received.
1852 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1853 but returns diagnostic set as well.
1855 New function yaz_strerror which is a portable wrapper for
1856 strerror/strerror_r/GetLastMessage.
1858 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1859 is returned for MARC. If type is "oai", then OAI MARC is returned.
1861 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1864 --- 1.9.2 2002/11/26
1866 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1868 Fix bad race conditions on SIGTERM and terminate gracefully in
1871 Move retrieval (data1) module to Zebra since nobody seems to be
1874 Add GRS-1 render for ZOOM using same format as yaz-client.
1876 --- 1.9.1 2002/10/05
1878 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1880 Fix broken ESpec handling in data1 module.
1882 SGML reader parses comments and makes them part of the data1 tree.
1884 Added several type casts so that YAZ compiles as C++ code.
1886 ZOOM didn't handle PDU encoding failures properly.
1888 Added more Bib-1 diagnostics (approved extensions).
1890 GNU configure: better check for iconv.
1892 More portable use of accept, getpeername. Check for socklen_t. Use
1893 int/size_t if socklen_t is not defined.
1897 PQF parser rejects bad queries - including those with extra
1898 characters in them. PQF parser used to silently ignore that.
1899 Cleaner API for PQF added, which allows you to get detailed
1900 error information for bad queries (see yaz/pquery.h).
1902 Fixed bug in ZOOM_record_get for type "database".
1904 Implemented mini iconv library supporting conversions between
1905 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1907 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1909 --- 1.8.9 2002/08/20
1911 Fixed ZOOM C record cache so that preferredRecordSyntax and
1912 elementSetName is used to check for already fetched records.
1914 --- 1.8.8 2002/08/02
1916 Added three members in bend_initrequest structure to facilitate
1917 character set negotiation.
1919 Fixed a bug in frontend server that could cause indefinite
1920 loops under rare conditions.
1922 Revised character set utilities (charneg.h) so that encoding
1923 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1925 For PQF, directive @term <type> sets term type for Scan/Search.
1926 Here <type> is general, string, numeric, null. The term type
1927 is inherited - just like @attr.
1929 New call odr_set_charset that sets character set conversion for
1930 international-strings on a ODR stream. Prototype is:
1931 int odr_set_charset(ODR o, const char *to, const char *from);
1932 The InternationalString is still represented as C string in YAZ
1933 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1934 won't). On the protocol level, you can use any encoding.
1936 Support for UNIX sockets in ZOOM.
1938 Solaris recv sometimes returns errno == ENOENT. It is treated as
1939 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1941 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1942 both client and server. Code by Morten Bogeskov.
1944 --- 1.8.7 2002/05/22
1946 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1947 that they can be used directly from Visual Basic. You must recompile
1948 your windows APP if you're using ZOOM.
1950 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1951 Commands "lang" and "charset" sets language and character set respectively.
1952 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1953 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1955 Attributes from multiple CCL fields may be OR'ed rather than merged
1956 using directive "@field or". Fields are still merged by default -
1957 equivalent to "@field merge".
1959 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1962 Fixed bug in zget for parameter ExtendedServicesResponse.
1966 --- 1.8.6 2002/03/25
1968 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1970 Client displays USR.1:SearchResult-1 (hits per term).
1972 Additional Search Info for search in Generic Frontend Server.
1974 Fixed CCL parsing of "field=s".
1976 WIN32 installer - using the excellent NSIS software from nullsoft.
1978 Fixed CCL parsing of "field = - <number>".
1980 Added function yaz_marc_decode that decodes MARC for line mode
1981 display or XML (similar to that used by JZKit).
1983 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1984 Z39.50. But ISO/ILL was, however.
1986 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1987 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1989 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1990 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1992 --- 1.8.5 2002/02/03
1994 New YAZ client features: Command completion and new commands:
1995 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1996 Code provided by Jacob Poulsen.
1998 New call oid_trav, that visits all registered OIDs via callback.
2000 Function ZOOM_record_get now returns const char pointer rather than
2001 void pointer. It saves a lot of type casts.
2003 For YAZ client, command "auth" now allows you to set authentication
2004 in IdPass style. It is enabled when three tokens are given - order
2005 is user, group and password.
2007 Fix memory leaks in MARC record handling for ZOOM.
2009 New option for YAZ client, -k <kilobytes> that sets
2010 maximum record size. Similar to -k option for generic frontend
2011 server and yaz-ztest.
2013 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2015 Prefix query parser reports "fail" when bad attribute set is given.
2017 Fix in MARC decoder. Proximity logging. Fix for attribute set
2018 in scan handler for server. Patches by Shigeru Ishida.
2020 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2023 Configure option --with-openssl=<dir> now works when a directory is
2024 specified. Patch provided by Morten Bogeskov.
2026 New option for YAZ client, -u <auth>, that sets authentication.
2028 ZOOM fix: error information was sometimes "missing", since error
2029 was cleared/reset too when it shouldn't.
2031 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2033 --- 1.8.4 2002/01/04
2035 Scan for ZOOM API. New object ZOOM_scanset. New functions
2036 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2037 ZOOM_scanset_destroy.
2039 New ZOOM function, ZOOM_connection_last_event, that returns type
2040 of last event (such as "receive data", "send data", "apdu received",
2043 New ZOOM option, schema, that specifies schema for retrieval.
2045 New CCL feature. Qualifiers can be aliases for one or more
2046 other qualifiers (if more than one is given, OR is used).
2048 ZOOM uses named result sets if target supports it.
2050 Two new YAZ client commands: . (dot, which sources a script of YAZ
2051 client commands), and ! (to execute shell command.). Implemented
2054 Working on Debian packages.
2056 --- 1.8.3 2001/11/19
2058 YAZ client enables named result sets only if target supports it.
2060 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2062 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2063 with key="host" to get same result.
2065 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2066 Function Z3950_resultset_record(s) returns references to records
2067 "owned" by resultset. To become owner use Z3950_record_clone.
2069 Function z_ext_record handles Extended Services. Thanks to
2072 --- 1.8.2 2001/11/12
2074 CCL Parser fix: ignore token comma when dealing with and-lists.
2076 Documentation updates for COMSTACK.
2078 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2079 Changed prototype Z3950_records. For some functions, int parameters
2080 were changed to size_t.
2082 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2085 New MARC decode/display function, marc_display_exl, which properly rejects
2086 non-ISO2709 records. YAZ client uses it.
2088 --- 1.8.1 2001/10/29
2090 Fix bug: local attribute set wasn't set correctly in PQF strings.
2094 * Old Z39.50 codecs no longer supported.
2096 Added ZOOM C binding. See http://zoom.z3950.org/
2098 Renamed states for COMSTACKs to avoid confusion with events.
2100 Implemented cs_look and proper cs_rcvconnect.
2102 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2104 Configure detects POSIX threads on OpenBSD.
2106 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2107 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2109 When error is returned from present handler, non-surrogate diagnostic
2110 is returned in present response (and fetch handler is no longer called).
2112 * Minor adjustments to pquery parser (PQF). Token characters may be
2113 escaped by using backslash (C-style).
2115 PQF parser allows string attribute values to be specified. For @attr,
2116 non-numeric characters after the equal-sign are treated as strings
2117 (e.g. @attr 9=title).
2119 CCL trunction character may be defined (@truncation in file)
2121 * function zget_ExtendedServicesRequest sets waitAction to
2122 waitIfPossible (was wait).
2124 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2127 CCL operator names may be set in field definition files (CCL_bibset).
2128 See ccl/bib1 for an example.
2130 Fixes in ASN.1 compiler for C++ compatibility.
2132 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2133 and "op_or" to avoid conflict with C++.
2135 Fixed problem with GNU readline detection on Redhat 7.0.
2137 Added step-size for Scan backend handler.
2139 Fixed bug that made the frontend server crash when no attribute
2140 set was specified for scan.
2142 Front-end server automatically switches to original working directory
2143 when installed as an NT service. Previously -w had to be specified to
2146 Added extended attributes for retrieval module (data1), so that data1
2147 records carry d1_readXML/SGML attributes. d1_read also supports
2148 null-data rules ( <tag/>)
2150 On UNIX when POSIX threads are available, a separate library libyazthread
2151 is created. Programmers should link with that library and the yaz library
2152 when using threads. The reason for the split was that some applications
2153 on Linux, such as Apache, doesn't work well when using shared objects that
2156 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2157 (or any frontend server) in SSL mode by specifying ssl: followed by
2158 address. Only tested on UNIX.
2160 Added feature for CCL module. Virtual structure s=al or s=ol generates
2161 and-list and or-list respectively instead of phrase search.
2165 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2166 log_mask_str. This was done to avoid name conflicts with other libraries
2167 (such as other PHP extensions).
2169 Added raw OID member for preferred record syntax (request_format_raw)
2170 and returned record syntax (output_format_raw) for backend fetch method.
2172 Config file yaz-config now accepts options so that it returns specific
2173 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2175 Shared library support for UNIX using GNU libtool.
2177 * Modified backend interface. Request/Response struct's replaced by
2178 one read/write C struct. For example bend_fetchrequest and
2179 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2180 Every handler - even search has to be registered in bend_init
2181 handler. This means that the YAZ library no longer refers to
2182 external functions and it makes it possible to make the whole
2183 thing a single DLL/SO.
2185 Added Segment handler for backend server.
2187 Added Zmbol/Zebra administrative functions to YAZ client.
2189 Threaded frontend server on UNIX (when POSIX Threads are available).
2190 Starting the server with option -T enables multi-threading.
2194 Added configure option --enable-comp/disable-comp to control use
2195 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2196 located in sub directory asn.
2198 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2199 in ${exec_prefix}/bin along with the other programs yaz-client and
2202 GNU automake used to maintain makefiles.
2204 Added several OID's.
2206 Changed retrieval module so that we can load records with no abstract
2207 syntax defined. Tagpaths in these records are fully composed of string
2210 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2214 On UNIX, the generated makefile now supports a proper 'make install'.
2215 The prefix can be set via GNU configure to set the install location
2216 (default is /usr/local).
2218 * YAZ programs client and ztest were renamed to yaz-client and
2219 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2220 locations, such as /usr/bin,/usr/local/bin,etc.
2222 * YAZ Header files were moved from include to include/yaz. YAZ Header
2223 files are referred to as include <yaz/log.h> rather than <log.h>.
2224 The YAZ include path (-I ..) is therefore the same as before. Programmers
2225 should update their #include statements or use -Ipath/include/yaz
2226 instead. The main motivation for doing this change is that YAZ header files
2227 can be installed in "standard" locations /usr/include,/usr/local/include
2228 without introducing conflicts, since ALL YAZ header files are stored
2229 in subdirectory yaz (under /usr/include for example).
2231 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2232 rather than project/workspace files. We switched because project files
2233 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2236 Changed name of logging function, logf, to yaz_log, to prevent name
2237 clash with some math-log functions. The YAZ header log.h defines logf
2238 to yaz_log (#define) so there should be no incompatibilities by this
2241 Added bend_start/bend_stop handlers for server. These handler are
2242 called on start/stop of server. For windows they are called whenever
2243 a service is started/stopped.
2245 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2246 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2247 in util/yc.tcl. The auto-generated C code structures are, in a few
2248 cases, incompatible with the old decoders. There are differences in the
2249 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2250 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2251 The preprocessor variable ASN_COMPILED is defined when the compiled
2252 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2253 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2254 wish to use the old encoders/decoders you can specify --disable-yc
2257 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2258 version so that it supports both new - and old version of DB Update
2260 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2261 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2262 change. The name parameter can be set to 0 in which no name is specified
2263 for the construction. The macros odr_implicit and odr_explicit sets name
2264 parameter to zero for the construction involved. New macros
2265 odr_implicit_tag and odr_explicit_tag are similar to the others,
2266 except that a name parameter is added. For programmers' that don't use
2267 ODR they probably only need to change the call to z_APDU and z_External.
2269 Added access control facility by interfacing the TCP wrapper library.
2270 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2271 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2272 name of the daemon and enables the access control as specified in
2273 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2275 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2276 den Dool <H.M.vdnDool@kub.nl>.
2278 Added reference ID parameter to most functions in server API - refer
2279 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2281 Changed name of ccl library to libccl.a (was ccl.a).
2283 Fixed bug in decoder for Explain (Category TargetInfo).
2285 Added support for GNU readline in client. Thanks to Jacob Poulsen
2286 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2288 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2289 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2290 IMPLEMENTATION! This change was made to the development version before
2291 the ZIG decided to retract the amendment. If any users MUST be
2292 compatible with the original Update definition, PLEASE CONTACT US, and
2293 we will include a separate definition corresponding to the old Update
2294 ES. Note that because of the change to the ASN.1 of the
2295 TaskPackageRecordStructure we cannot define a single structure that
2296 will support both versions.
2298 * Added const modifier to buffer parameter for some ODR/BER encoding
2299 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2300 completeWAIS, odr_dumpBER.
2302 Fixed bug in client.c which caused a crash when a scanResponse didn't
2303 contain positionOfTerm.
2305 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2306 * will cause an error in a client if a non-YAZ target sends both a
2307 * list of Scan entries and non-surrogate diagnostics.
2309 Retrieval module enhancements. Tag sets may be typed in the reference
2310 to it. From the .abs-file the "tagset" directive takes a third optional
2311 integer type for the tag set referenced. From a .tag-file the "include"
2312 directive takes a third optional type as well. The old "type" directive
2313 in the tag set itself is still recognized but acts as the default type
2316 Backend interface change. Individual Scan terms returned from bend_scan
2317 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2318 in include/backend.h.
2320 Retrieval module enhancements. Multiple tag sets and attribute sets may
2321 be specified in abstract syntax specs. Revised the error/warning for
2322 logging messages reported by the retrieval module when reading the
2325 Object Identifier system (oid_..) changed. The API is backwards
2326 compatible but the oid-routines now allocates new OID's when needed.
2327 Raw OID's may be specified in oid_getvalbyname.
2329 YAZ now uses GNU configure to generate Makefile(s).
2331 * Minor changes in some of the member names of DeleteResultSetRequest and
2332 DeleteResultSetResponse. See include/proto.h.
2334 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2335 and added member 'languages' in TargetInfo (which was missing).
2337 Changed the way attribute sets are handled in the retrieval
2338 module. These are now cached, just like the abstract syntaxes
2341 Changed YAZ so that it links with compiled ASN.1.
2343 Added Explain-schema definitions and mapping routines. The following
2344 Explain categories have been implemented: AttributeDetails,
2345 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2347 Fixed minor bug in Windows version of Server Library.
2349 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2351 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2353 Added EXTERNAL: UNIverse Resource Report (non-standard).
2355 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2356 ENUMERATED and SET OF.
2358 * Added 'const' to some of the char pointer arguments for the
2359 functions, data1_read_node, data1_getelementbytagname,
2360 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2363 Fixed bug in data1_insert_taggeddata - the last_child member of
2364 parent wasn't initialised.
2366 * Changed data1_read_record and data1_read_node so that the supplied
2367 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2368 doesn't refer to any parts of the "SGML"-buffer.
2370 Fixed bug in server library (Windows version of statserv_remove).
2372 * Changed code so that it compiles as C++. The type definition
2373 of Odr_fun which is a member of Odr_arm was changed. The result is,
2374 that an explicit typecast is needed for the fun pointer when
2375 using Odr_arm - as in:
2376 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2378 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2380 Implemented the new structured date and time definition as approved
2381 by the ZIG. Added schemaId element to the specificTag in Espec-1
2382 (also approved at the last ZIG). Thanks to RVDM.
2384 Added some Object identifiers (RVDM).
2386 Changed the Update Extended Service (RVDM).
2388 Added command "refid" to client which specifies referenceId for
2389 the following requests.
2391 Implemented extended service handling for server. See ztest.c
2392 for an example as well as backend.h. New handlers are registerd
2393 in the Init handler.
2395 * Changed interface for sort in server.
2397 Added new members to statserv_options_block. It allows a server
2398 to read options from another source than just the command line. Thanks
2399 to Charles Woodfield.
2401 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2402 renamed to zboolean. Some C++ compilers complained about the name.
2404 Minor changes to gils.abs. Added index 's' (sort) on title
2405 and date/time-last-modified.
2407 --- 1.4pl2 1998/1/30
2409 Fixed bug in server library regarding inetd mode (-i). This bug
2410 was introduced by release 1.4.
2412 --- 1.4pl1 1998/1/29
2414 Added sort facility in client and backend server interface.
2416 Fixed problem with dependencies in Makefile(s).
2418 Fixed bugs for encoders/decoders of extended services and
2421 Implemented sub-tree feature for schemas. Sub-trees are
2422 referenced in *.abs-files. See explain.abs for an example
2423 of the use of this feature.
2425 Modified bib1.att; local attributes for ANY didn't include
2426 ANY itself (only affects use of the retrieval module).
2428 Fixed bug in plain SGML reader in function data1_read_node:
2429 tags with prefix "var" was incorrectly interpreted as variants.
2431 Added feature "sub-schemas" to enable references to - and definitions
2432 of - group of elements.
2434 * Removed member parent from type data1_element (in data1.h).
2436 Implemented function odr_nullval() that returns the value of
2439 * Removed member num_children from data1_node (in data1.h).
2441 Made NT service interface part of the server library. The
2442 function statserv_main uses the NT service when required and
2443 calls the statserv_start / statserv_close routines.
2445 Routine zget_SearchRequest and zget_PresentRequest fills
2446 resultSetName/Id member with "default" instead of "Default".
2448 Fixed memory leak in server. Request queue member wasn't freed.
2450 Fixed nmem_exit so that memory is freed.
2454 Revised the CCL parser utility to be thread safe.
2456 Added function, oid_ent_to_oid, to replace the function
2457 oid_getoidbyent, which is not thread safe.
2459 * Added nmem_init and nmem_exit to initialize and release
2460 NMEM resources. Function nmem_init should be called once in the
2461 initial thread before NMEM/ODR is used. statserv.c and client.c
2462 have been changed accordingly. The change was necessary to make
2463 NMEM thread safe. The NMEM memory pool is shared amongst threads
2464 in a process. Unix-based applications will still work fine without
2467 Added NT Services interface for the the Z39.50 (statserv) Server.
2468 Refer to the ztest.c source on the usage.
2470 Windows 95/NT port using MSVC5.0. Project files are included in the
2473 * Defined new 'global' handle for the retrieval (data1) system. The
2474 new handled, data1_handle, describes the state of the data1 system.
2475 This handle is passed as first argument to virtually all
2476 data1 related routines. The functions data1_create and data1_destroy
2477 creates and destroys a data1 handle respectively.
2479 Added ODR encode stream member to all backend request structures
2480 init, search, scan etc. This stream should be used to allocate all
2481 memory used for the response when thread safe operation is needed.
2483 Changed the comstack utility, cs_addstr, to be thread safe. The
2484 returned hostname string returned by the function is now part the
2487 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2488 function. The cs_straddr takes a COMSTACK handle as argument, so this
2489 function must be used after cs_create and before bind/connect.
2490 This function is thread safe.
2492 Moved test server to 'ztest' directory - generic server code still
2493 in 'server' directory.
2495 Made prefix query (pquery.c) utility thread safe.
2497 Added new function modifier YAZ_EXPORT to 'export' public DLL
2498 functions when using windows (see include/yconfig.h).
2500 Added definitions to the OID database (util/oid.c) (RVDM).
2502 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2504 Added call to ccl_rpn_delete in client program.
2506 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2507 release of RPN structure.
2509 Added support for C++, headers uses extern "C" for public definitions.
2510 With input from RVDM.
2512 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2513 Thanks to Ronald van der Meer (RVDM).
2515 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2517 Added support for private extensions to the OID database
2518 (oid_setprivateoids()). Thanks to RVDM.
2520 Added optional, physical ANY (key replication)
2522 Fixed null-reference problem in GRS-1 output filter.
2524 Proximity operator added to Prefix Query Format (PQF).
2526 In test client command "base" accepts multiple databases.
2528 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2532 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2534 Smallish bug-fixes in the new encoders/decoders (explain).
2536 Bug fixed in DeleteRequest.
2538 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2540 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2542 Added SOIF syntax (using private OID for now) to retrieval module and client.
2544 Added Update extended service.
2546 Added SearchResult-1 additional info structure.
2548 Added optional CCL (ISO8777) interpreter as separate module. Available
2551 --- 1.2 1996/6/10 (1st anniversary release)
2553 Added Summary record syntax. Lightly tested.
2555 Added OPAC record syntax. Untested.
2557 Added ResourceReport service encoders/decoders. Untested.
2559 Fixed bug in z_Unit - wrong tagging on unitSystem.
2561 Fixed bug in the DiagRecs decoder.
2563 Added options for max PDU size and session timeout to frontend-server.
2565 Added documentation of query-language parsers and other supporting utilities.
2567 [frontend-server] Added Attribute set to the bend_scanrequest API.
2569 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2570 surrogate diagnostics were generated.
2572 [retrieval] Allow multiple local values for attribute.
2574 [retrieval] Allow multiple attributes per element in .abs files. index type.
2576 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2578 --- 1.1pl2 1996/4/10
2580 Minor changes, mostly specific to Zebra's requirements (retrieval)
2584 Repaired bug in frontend server when running multiple listening
2585 endpoints in dynamic mode.
2587 z_External() now won't break if a known, ASN.1 value comes encapsulated
2588 in an octet-string. The value will pass through unmodified in an Odr_oct.
2590 Added a bit of code to the demo client to decode & display
2591 ASN.1-structured records represented in the octet-aligned branch of
2592 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2594 Added z_ext_getentbyref() to the ASN module. Doc updated.
2596 * Completed the SCAN definition in the ASN module. This may break SCAN
2597 code based on older YAZ-versions at compile-time. The fix is easy -
2600 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2601 under the SCAN definition. Remember to initialize this, server-people.
2603 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2604 that this does not extend to ODR and ASN.
2606 Comstack allows insertion of established socket (primarily for
2607 inetd-operation of servers). Doc updated.
2609 Front-end server can now start from the inetd in TCP mode. Doc
2612 --- 1.0pl4 1996/1/24
2616 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2617 the rank and record number.
2619 Adjustments to the frontend server.
2621 Fixed diagnostic BER dumper. It ignored the file argument.
2625 Various changes to retrieval module.
2627 Changed the union discriminators of the protocol files from enums to
2628 ints paired with #defines.
2630 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2633 *Changed operator in the RPN structure to 'roperator', again to avoid a
2636 Fixed problems in Explain decoders/encoders.
2638 --- 1.0pl2 1995/12/6
2640 Memory bug in log module fixed.
2642 --- 1.0pl1 1995/12/5
2644 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2646 Bug in Explain DatabaseInfo module fixed.
2648 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2652 The shift to v1.0 signals that we now consider the *core* functionality
2653 of YAZ reasonably stable (the core being more or less equivalent to
2654 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2655 tested (Explain not at all - though that will happen soonish).
2657 Minor changes to code to support Windows port.
2659 Various minor changes after we're getting to use GRS-1 & co. more.
2661 Added Espec-1 format.
2663 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2664 of the protocol and it cannot be selected when encoding (maps into 'string'
2665 when decoding). Needed to talk to some servers.
2667 Demo client can request simple element set names.
2669 Added Diagnostic Format encoders/decoders.
2671 Added simple Close handling to frontend server (no hooks for resource
2672 reporting yet), and demonstration client.
2674 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2676 --- 1.0b3 1995/08/24
2678 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2679 handled incorrectly when records were requested in the searchResponse. This
2680 will only affect you if you use the frontend-server.
2682 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2683 Test-client will ask for and print GRS1. Ztest will return dummy records
2686 Added Explain encoders/decoders to the service-level API. Untested.
2688 Added Extended Services: Item Order encoders and decoders to the Service-
2689 level API. Untested. We could use a recent copy of the pertinent bits
2690 of the ILL protocol to add those bits.
2692 Added diagnostic format 1 encoders/decoders to the service-level API.
2695 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2696 odr_cons.c, which causes a more correct output.
2698 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2699 was always set to 0 when no records were requested in the searchRequest.
2701 * Added better external-handling. This shouldn't harm old code that
2702 *encodes* externals. It can break code that looks for a
2703 'single-ASN1-type' representation, since those types that are known
2704 are now decoded immediately. Look at the SUTRS sample code in
2705 seshigh.c and client.c. Documentation updated.
2707 Handling of structured records in bend_fetchresponse. Length -1 marks
2708 structured record, type is deduced from format field.
2710 --- 1.0b2 1995/06/27
2711 Fairly quick maintenance release to add SUTRS support.
2713 Fixed handling of SUTRS records in the demonstration client.
2715 * Added format field to the bend_fetchrequest and bend_fetchresponce
2716 structures of the backend API (frontend server). When the record is
2717 returned, the value of the format field is mapped to an OID. The
2718 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2719 of the record. The special value VAL_NONE in the bend_request means
2720 that no specific format was requested by the client. Documentation
2721 updated accordingly. Test server (ztest) will return a fixed dummy
2722 SUTRS record if your client requests SUTRS.
2724 Documentation updated accordingly.
2726 You can now set external libraries and RANLIB support in the top-level
2730 First public release.
