3 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
4 result set from a connection. The result set will be on its own
5 thereafter; no operations on it will perform retrievals from a target.
6 Only cached copies are returned.
8 ZOOM C:fix case for HTTP servers responding with Connection:close.
9 Ensure that if there is a current task it is resumed (like fetching
10 more records in a result set) . Bug #3484.
12 PQF parser: use odr_atoi for Odr_int (not atoi)
14 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
15 values that contain any non-digits are treated as string attributes
16 (previously decoding only checked for leading character ([0-9]). PQF
17 encoding: attribute string values are not surrounded by double-quotes.
21 New utility for managing threads - thread_create.h.
23 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
24 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
25 but YAZ' implementation do.
27 Fixes for yaz_cond-functions on Windows 7.
29 DLL export more symbols.
31 zoomsh: show record do NOT render opac.
33 Remove *.la files from Debian and RPM packages.
37 Debian package libyaz-dev depends on libgnutls-dev again (was
38 removed in YAZ 4.0.6, but due to Libtool it is still needed
39 even though yaz-config do not list libgnutls libs).
41 ZOOM: Use only one WRBUF for returning string results for
42 ZOOM_resultset. Reduces memory usage for ZOOM in general.
44 ZOOM: ZOOM_connection do not use a shared pointer to
45 ZOOM_resultset after ZOOM_resultset is destructed by
46 user. Reverts to YAZ 4.0.4 behavior.
50 record-conv: fix problem with at least one XSL conversion -
51 due to probably incorrect usage of XML XSL documents.
55 Fix yaz-config for static mode and the use of SSL (gnutls).
59 Forward decl timeval struct in mutex.h and gettimeofday.h.
61 yaz-config: fix 'static' mode linking.
65 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
66 are wrappers for pthreads or Windows. For Windows these are put in
67 a separate DLL: yaz_cond4.
69 libyaz.la (whole source) is compiled with thread. If thread support
70 is enabled enabled, all source of YAZ is compiled with treading support.
71 This allows core utilities such as yaz_log to use thread facilities.
72 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
73 thread utilities. This commit moves mutex utilities (mutex.c) from
74 libyaz_server.la to libyaz.la.
76 yaz-json-parse displays leading text until error.
80 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
81 patch from Giannis Kosmas.
83 SRU: no longer URL encode SRU database. The URL for an SRU server is
84 a URL and such is alreeady encoded - at least when given with leading
85 http:// or https://. This reverts behavior to YAZ 3.0.50.
87 Support for new MARC XML notation TurboMARC which like MARCXML is a
88 complete representation of MARC/ISO2709.. This one, however, is more
89 compact and allows for faster processing with XSLT. TurboMARC can be
90 used in the marcdisp.h API, from the yaz-marcdump utility and from
93 yaz-ztest can be configured - via the database - to perform certain
94 delays when it performs operations search, present and single record
95 fetch. This allows testers to make yaz-ztest act as a real or even slow
96 Z39.50 server. Refer to the yaz-ztest man pages for details.
100 wrbuf_destroy allows NULL WRBUF passed to it.
102 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
104 Add ZOOM_connection_close.
106 No fixed size buffers for ZOOM shell - bug #3257.
108 tstodr: make it work on s390 platform.
110 New icu iterator-functions. The new icu_iter-functions makes it possible
111 to use ICU chains from many threads.
113 yaz-client: better syntax check for show command.
117 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
120 New simple local-file XML include facility which allows file glob-patterns.
121 Refer to yaz/xml_include.h.
123 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
126 ZOOM_record_get supports new parameter "format" which makes it format XML
129 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
130 JSONText in ECMA-262) is JSONValue, not JSONObject.
134 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
135 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
137 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
138 POSIX/Unix builds .so with major version 4.
140 Remove old LOG_-defines from log.h. They have been obsolete and
141 undefined by default for the last 5 years.
143 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
145 GFS: Remove socket (int *fd) from search_rr handler. The socket
146 descriptor ptr is a facility that allowed a search handler to supply
147 a socket which would serve as a callback - when search was complete.
148 This facility has now been in use for years.
150 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
151 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
152 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
153 returns 'const char *' rather than 'char *. The returned string is
154 read-only and should not be modified by applications. COMSTACK cs_close is
155 now a void function - it no longer returns int. No applications check for
156 the value and the implementations has always returned 0.
158 ZOOM: use size_t for scan hit counts and str size. Functions
159 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
160 occ (hit count) and len (string length) are now of type size_t pointer
161 rather than int pointer. This is to be able to represent large hit counts
162 and to also just to use the proper type for string length (strlen result).
164 New JSON parser. Refer to include/yaz/json.h .
166 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
167 Used to be int in some cases. Many wrbuf_-functions used to return an int
168 indicating some length.. These return values were never used. And so they
171 ODR: odr_malloc, odr_total now takes size_t for size.
173 clone_z_type: fix leak; occurred for encoding failures.
175 --- 3.0.52 2009/12/03
177 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
178 bug was introduced in 3.0.51.
180 --- 3.0.51 2009/12/02
182 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
184 tcpip comstack: fix leak for getaddrinfo.
186 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
187 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
188 Decoding of SRU "path" database is performed by private function
189 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
190 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
192 yaz-client: honor base command for SRU. Change when database setting
193 is applied for SRU and ensure it is kept when a connection is reset.
194 Change also the way errors are displayed or SRU (decoding of packages).
196 --- 3.0.50 2009/11/02
198 Add support for extra request / response data for SRU codecs and GFS.
199 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
200 for extra data response buffer and length. For the GFS, both request
201 and response data (XML) is carried in extra_args and extra_response_data
202 for the search handler. Patch by Ko van der Sloot.
204 ZOOM: For queries that cannot be converted to the specified rpnCharset,
205 ZOOM now returns a diagnostic on the client-side ('invalid query' /
206 10010). This fixes bug #2113.
208 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
209 cmdfile included a 'quit' command that would result in a memory violation.
211 --- 3.0.49 2009/10/01
213 Make a number of functions defined in xmlquery.c static. These have
214 never been declared in a public header file (yaz/xmlquery.h) and was
215 made public by mistake.
217 Improve speed of character conversions (iconv utilities). This makes
218 conversions from MARC-8 faster.
220 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
221 unless type desired is "raw". This will prevent type "xml" from
222 returning ISO2709 .. Which obviously can not be XML parsed.
224 Fix memory leak in ZOOM that would occur if option apdulog was used
225 on a re-used connection.
227 Frontend server logs HTTP requests.
229 Frontend server now sends Z39.50 close when it times out (sesssion has
230 been idle for too long). Versions 2.0.30 and earlier also sent close.
231 But due to a mistake this was disabled in all versions after that, i.e.
232 the server would just close the socket immediately.
234 yaz-client emits a better message when receiving an unrecognised
235 userInformationField.
237 Skip zero-length subfields when decoding ISO2709. This rare case happens
238 if a record has two FS characters in a sequence. Without this patch
239 there would be a reference beyond char array in using_code_len fragments
242 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
244 --- 3.0.48 2009/08/28
246 The show command offered by the zoomsh command now takes a 3d optional
247 parameter type which is what is passed to ZOOM_record. If the type
248 argument is omitted, "render" is used.
250 RPN to CQL conv may use USE string attributes (bug #2978).
252 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
254 --- 3.0.47 2009/07/08
256 Function yaz_xml2query allows a diagnostic element in the PQF XML
257 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
258 code and additional info respectively.
260 The BER BOOLEAN is now the integral type Odr_bool which still happens
261 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
262 typedef'd to Odr_int. This is still an integral 'int', but it may be
263 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
264 ASN-1 compiler as well as programs has been updated to use the new types.
266 --- 3.0.46 2009/06/08
268 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
269 only the bibliographic record was rendered. For type=opac, an OPAC
270 record is only returned if it is present.
272 iconv: small fix for encoding of advancegreek.
274 yaz-client: avoid double display of SRU/SRW records (bug #2798).
276 yaz-client: option auto_reconnect=on really reconnects.
278 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
280 server: avoid null ptr ref for for yaz_poll errors.
282 build: fix RPM build for RHEL 5.3.
284 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
286 --- 3.0.45 2009/03/31
288 Fixed bug #2709: TCP connect returns Invalid argument.
290 Fixed compilation for mingw.
292 Honor charset for raw records (ZOOM_record_get).
294 Fixed use of errno for threaded mode that was seen on Solaris 10.
296 Fixed argument passing with blanks in value for Windows Service.
298 Disable YAZ' own log rotate by default (no 1 GB limit).
299 The variable l_max_size which specifies the log file limit is set to 0
300 (DISABLED): This is due to the fact that YAZ is most often deployed using
301 logrotate. Also YAZ can not perform log rotate because of unsufficient
302 permissions (setuid).
304 --- 3.0.44 2009/02/17
306 List supported encodings in man page for yaz-iconv.
308 Fixed missing SSL libs for --libs output
310 Re-established OID record syntax application-xml. Nobody should use it
311 but we don't want to change soname because of this symbol being absent.
313 --- 3.0.42 2009/02/02
315 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
317 Added member named_result_sets for init handler struct for the GFS. This
318 allows a server to disable named result sets.
320 Removed OID record syntax application-xml.
322 Added support for rule-based transliterator for ICU wrapper of YAZ.
324 Fixed bug #1902: yaz-icu XML output.
326 Make YAZ checks Emacs friendly.
328 BITSTRING value shows value. Bug #2346.
330 ISO2709 decoding: skip control characters from indicator data.
332 Omit sort key by default in yaz-icu's output.
334 Allow combined single char options (again) for YAZ' options function.
336 Utility yaz-marcdump got option to display YAZ version (-V).
338 Allow YAZ to use ICU 3.4.
340 Added new ICU test case which illustrates removal of diacritics.
342 --- 3.0.41 2008/12/29
344 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
346 --- 3.0.40 2008/12/29
348 For configure, using option --without-xml2 also disables Libxslt/Libexslt
351 Fixed bug #2352: yaz-marcdump crashes for certain record.
353 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
355 Added support for Danmarc2 to UTF-8 conversion.
357 Added support for ISO5426 to UTF-8 conversion.
359 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
360 implementation version.
362 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
364 --- 3.0.38 2008/11/10
366 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
367 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
369 ZOOM C now interprets databaseName option for ZOOM connection as path
372 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
374 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
376 Dummy Libxml2 types no longer defined in headers of YAZ'.
378 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
381 --- 3.0.36 2008/09/26
383 Various ODR chapter fixes.
385 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
387 Added missing source for Windows compilation, mutex.c.
389 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
391 For SRU connections in ZOOM all records up to "count" are now fetched.
393 Fixed crash in generic frontend server (and yaz-ztest) which occurred
394 in Windows due to bad error handling for Libxml2.
396 Added facility for sending arbitrary records (ASN.1 any) using
397 ZOOM C's Extended service update. Patch by Sam Reynolds.
399 New options for ZOOM C's connection, logapdu which makes ZOOM log
402 --- 3.0.34 2008/06/18
404 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
406 --- 3.0.32 2008/06/12
408 Fixed memory violation that could occur when decoding UTF-8. This bug
409 was only present in 3.0.30 of YAZ.
411 --- 3.0.30 2008/06/06
413 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
414 GNU TLS is used by default (if found).
416 yaz-ztest returns OPAC records if a client asks for OPAC.
418 Improved speed of MARC-8 encoding.
420 Added support for lossy and loss-less MARC-8 encoding.
422 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
424 Added new Windows Service wrapper (sc).
426 yaz-client's itemorder command may now send a file.
428 Fixed yaz-marcdump to allow the use of NS prefix for record element.
430 Added new function yaz_log_xml_errors.
432 Allow (but warn) unknown XML attributes in MARCXML parsing.
434 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
436 The UTF-8 to MARC-8 conversion now uses a different set of characters
437 for Greek symbols. Bug #2120.
439 --- 3.0.26 2008/02/21
441 Added yaz_daemon (daemon.h).
443 Fixed bug #2068: pkg-config trouble
445 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
447 --- 3.0.24 2008/01/28
449 Document --with-xml2 option.
451 Added OPAC XML XSD (etc/opacxml.xsd).
453 Allow glob mask for name attribute in retrieval element for the
454 generic frontend server's retrieval facility.
456 Changed yaz_poll_poll to return yaz_poll_except for all returned events
457 except POLLIN/POLLOUT.
459 Fixed error handling in cs_listen. Bug #2037.
461 --- 3.0.22 2008/01/20
463 Fixed version in yaz/yaz-version.h.
465 Fixed bug #2027: Crash when closing connection.
467 Changed configure so that ICU support is only enabled if only ICU
468 and Libxml2 is available (because the ICU chain is XML based).
470 --- 3.0.20 2008/01/15
472 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
473 is built. Only this DLL depends on the ICU runtime.
475 yaz-ziffy is no longer part of YAZ. It is distributed separately by
476 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
478 Changed license of CCL module to 'Revised BSD'. After consultation with
479 remaining members of the original EUROPAGATE consortium, we are re-issuing
480 the CCL module without a separate license. The software was developed by
481 Index Data as part of a research project. The special license was included
482 to help feed usage information back to the project consortium to support
483 project evaluation. At this time, the project consortium has long-since
484 disbanded, and the majority of the original principals have retired. At the
485 same time, we have significantly modified the software during the following
486 years, to the point where very practically no original code remains. To
487 simplify re-use of the software, we have contacted those members of the
488 consortium who could be reached, and agreed to re-issue the module as a
489 proper part of the YAZ package.
491 Tcl scripts uses /usr/bin/tclsh as preferred shell.
493 CQL closer to being version 1.2 compliant. CQL also allows free-form
494 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
497 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
498 bug could make Extended services handling crash in the ZOOM layer. This
499 bug was only present in YAZ 3.0.18.
501 --- 3.0.18 2007/12/19
503 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
506 yaz-marcdump reads and writes collection wrapped records.
508 Handle OPAC for record conversion module.
510 Fixes for ICU wrapper.
512 Allow ICU libs to be controlled with --with-icu .
514 --- 3.0.16 2007/11/12
516 Added yaz_poll which is a wrapper for select/poll. When poll is available
517 and non-buggy, it is used, by yaz_poll . This allows more than 1024
518 sockets to be in use.
520 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
521 functionality through an XML based configuration (ICU chain). This system
522 is useful for search facilities such as Pazpar2 and Zebra that needs to
523 perform tokenization of indexed material. The ICU code in a separate
524 library libyaz3_icu.a.
526 Added HTTP tunnel facility for COMSTACK, bug #1752.
527 This is a facility that allows a Web proxy, such as squid, to tunnel
528 Z39.50 traffic. This facility is "transparent" to must applications
529 using YAZ. It's enabled by using pseudo transport connect: followed by
530 the proxy address, followed by command, then follwed by he regular
531 "virtual" addresss. For example,
532 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
534 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
536 --- 3.0.14 2007/09/21
538 Fixed bad memory reference in ZOOM_record - cuased by member not being
539 initialized. This was a problem only in YAZ 3.0.12.
541 Fixed bug in conversion from MARC to XML: Non-XML characters in control
542 fields were not removed.
544 Changed the way C code is generated from codetables.xml. Made a MARC-8
545 conversion trie for each characterSet section rather than codeTable.
546 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
547 of codetables.xml from Larry Dixson, LOC. Bug #1464.
549 --- 3.0.12 2007/09/12
551 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
552 from ZOOM_record_error).
554 ZOOM C function ZOOM_record_get returns record schema for type="schema".
556 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
558 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
560 Better SRW-to-Bib-1 diagnostic mapping.
562 ZOOM C and yaz-client announces SRU version 1.2 by default.
564 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
567 Fixed in yaz_sru_decode to allow other version than 1.1.
569 --- 3.0.10 2007/08/22
571 Added support for SRU scan for ZOOM.
573 Added support for the use of the older versions or Extended Service
574 Update in ZOOM. To faciliate this, an option "updateVersion" may be
575 set to the version , 1=first, 2=second, 3=third. The third version is
576 what ZOOM C has used so far. And that, obviously, is the default.
578 Added support for CCL queries in Z39.50 queries sent to the GFS (and
579 therefore in Zebra and in SimpleServer-based applications). The new
580 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
581 qualifier file used to transform incoming CCL queries into Type-1 RPN,
582 which is passed into the back-end search callback function.
584 Added support for HTTP Basic authentication in clients: the SRU/W
585 codec encodes the username/password elements of the PDU structure
586 appropriately, and these may be set using the "user" and "password"
587 options in ZOOM-C applications (the same options that are used for
588 Z39.50 authentication).
592 Fixed bug #1208: SSL appears to be broken in ZOOM.
594 Fixed bug #1206: Libxml2 include path weirdness.
596 Added oid_name_to_dotstring.
598 Allow elementSetName to be specified for ZOOM C record update.
600 Allow waitAction to be specified for ZOOM C based for Extended Services.
602 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
603 syntax OID. Bug introduced in YAZ 3 series.
605 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
609 Fixed bug #1157: yaz-client does not read .yazclientrc from current
610 directory. yaz-client now reads commands from file given by option -f
611 if specified; then tries to read .yazclientrc in current directory.
612 Failing that, it reads .yazclientrc from user's home directory.
614 Added support for correlationInfo Note and ID for Record Update via
617 Added yaz-client command querycharset which specifies character set for
618 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
619 (termListAndStartPoint).
621 Charset ISO5428:1984 is an alias for ISO5428-1984.
623 Implemented a way to perform scan in a result set using Z39.50. This
624 is achieved by attaching the result set name in the characterInfo
625 (type InternationalString) of OtherInformation in the Scan Request PDU.
626 The result set is identified in the otherinformation by the new OID:
627 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
628 This allows for scan in result set and faceted search . Zebra did some
629 of this in the APT term using attribute type 8 and value being result
630 set. Using the OtherInformation approach for this is cleaner and easier
631 to work with in proxies and the like. This facility can be used in
632 yaz-client using new command setscan which takes a result set as first
633 argument, start position (APT) as second.
635 Changed decoding of SRU XML packed records to deal with servers that
636 have recordData with XML data with multiple root nodes. Also make
637 comparison for recordPacking case insensitive. Again, one server
638 returns "XML" where others return "xml".
640 For SRU responses allow Content-Type application/xml as well as text/xml.
644 Fixed bug in character set conversion of BER strings. Bug introduced
649 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
651 For OID class, use oid_class consistently.
653 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
656 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
657 character set for bibliographic information interchange". By Giannis Kosmas.
659 Added documentation on new OID API.
663 Changes to generic frontend server interface: added new member
664 'query_charset' for bend_initrequest structure. A backend init handler
665 should set this member to its native character set for query terms.
666 When defined, the frontend server logic will announce this character set
667 to a client if the negotiationModel bit is set by the client. All server
668 implementors are encouraged to specify this. If a backend server does not
669 specify this a warning is issued using yaz_log(YLOG_WARN,..).
671 Added CCL utility to remove terms (stop words) from resulting RPN
672 tree. This is handled by functions with prefix ccl_stop_words_ .
674 New ZOOM C option, "rpnCharset", which allows client-side conversion of
675 terms in RPN queries.
677 Clean-up the CCL API. Moved some internal structures from ccl.h to
678 private header cclp.h. Changed ccl_parser_create so that a Bibset must
679 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
680 This is replaced by ccl_parser_find_str which takes a string instead.
682 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
683 libyaz.la is the core of YAZ except the generic frontend server and
684 does not depend on POSIX threads anymore. libyaz_server.la is the
685 generic frontend server facilities and uses POSIX thread functionality
686 if available. The libyaz.la no longer depends on POSIX threads because
687 the number of global structures is limited. NMEM no longer re-uses blocks
688 between threads ; it simply free's memory immediately but allocates in
689 "large" chunks as usual. We don't expect any performance penalties
690 because of this. The yaz_log system is still using a global log_level so
691 caution must be taken when modifying it with yaz_log_init_.. +
692 yaz_log_mask_str. This, however, should not cause any trouble because
693 these functions are called during initialization of application code
694 anyway. `yaz-config --libs server` returns libs for server applications;
695 `yaz-config --libs` returns libs for non-server applications.
697 New OID database - with public definitions in oid_db.h. Removed old OID
698 database including the head oid.h and definitions such as enum oid_value
699 and struct oident. The new OID database uses the same string names as
700 before but the 'protocol' is gone. There are now only two representations
701 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
702 converts from string to OID; functions with prefix yaz_oid_to_string
703 converts the other way.
705 Change to emit_term() in CQL-to-PQF query translation: when a term has
706 the /regexp relation modifier, do not process it for leading and
707 trailing "^" and "*", which have quite different meanings in regular
710 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
711 write handlers no longer carries a 'last' parameter. This will make
712 yaz_iconv flush "less" characters. A flush is performed by call to
713 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
715 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
716 removed, because function yaz_query_to_wrbuf does the same.
718 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
719 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
721 Deprecated MARC utility functions removed.
723 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
726 Branch split: YAZ_2_1_55_branch
728 --- 2.1.54 2007/03/16
730 Fix to ZOOM-C so that transparent reconnection is properly handled on
731 connections that are in asynchronous mode.
733 Fixed compilation on OpenBSD 4.0.
735 Large strings in GRS-1 records are now properly displayed in yaz-client.
737 Added character conversion support for "advancegreek"; based on patch from
740 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
741 sequence is met. Before the error was not set so it would be unknown.
743 Adjust yaz-marcdump MARC reader so that it skips until record separator
746 --- 2.1.52 2007/03/07
748 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
749 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
750 fd_set structure used as a bitmask for the FDs to be selected on.
752 Using ACX_PTHREAD macro to check for POSIX threads.
754 Fixed have-vsnprintf check.
756 --- 2.1.50 2007/02/23
758 Fixes for configure on BSD. Bug #900.
760 Added snprintf/vsnprintf wrappers for systems that don't have
761 limits (heavens forbid).
763 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
764 created before all previous tasks were completed and removed from the
765 task queue, the new task could be removed by a mistake.
767 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
769 Implemented pass-through CQL-to-PQF conversions. Bug #861.
771 Fixed bug #832: Problem with MARC/charset in yaz-client.
773 Fixed bug #668: save command line history for yaz-client.
775 Fixed bug #830: pkg-config support.
777 --- 2.1.48 2007/01/23
779 Extended ZOOM result set options with two options that may be read by
780 a client: resultSetStatus and presentStatus with values as specified for
782 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
784 Fixed bug #827: Using SSL fails on Debian etch.
786 Fixed bug #826: Weird looking chars for set of MARC records.
788 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
789 that is treated as an ItemOrder with itemRequest being an XML document
790 external. The value of "doc" is the content.
792 Extended the GFS search facility. New member of bend_search_rr
793 'estimated_hit_count' signals that hits is known to be an estmate
794 (higher or lower than real hit count). New member 'partial_resultset'
795 signals that the search was partial (hit count is lower or equal than
796 real hit count). For Z39.50, the information is stored in resultSetStatus
797 member of SearchResponse APDU. For SRU, the information is signalled
798 via SRU diagnostic 59: "Result set created with valid partial results
801 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
803 --- 2.1.46 2007/01/13
805 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
807 Added ZOOM_connection_peek_event.
809 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
810 the following new functions:
811 ZOOM_event_nonblock, ZOOM_connection_process,
812 ZOOM_connection_get_{socket,mask,timeout},
813 ZOOM_connection_fire_event_{timeout,socket}.
814 The existing blocking event handler, ZOOM_event, is a wrapper for the
815 + blocking ZOOM_event_sys_{poll,select}.
817 Implemented function ccl_xml_config which parses XML version of CCL
818 configuration (bug #798).
820 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
822 Added timings utility (yaz/timing.h)
824 --- 2.1.44 2007/01/03
826 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
829 Fixed bug #779: Rotation of apdu.log fails.
831 Fixed for character set conversions:
832 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
833 Honor G1 set in MARC-8 decoding.
835 --- 2.1.42 2006/12/17
837 Fixed bug #775: char conversion does not handle Alternative UTF-8
840 Implemented function yaz_marc_read_line which parses MARC line format
841 records. There is a wealth of formats out there. So far, this function
842 reads line records produced by yaz_marc_write_line.
844 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
845 more generic and easier to remember(!) options: -i format and -o format
846 which specifies input format and output format respectively - where
847 format is one of "marc", "marcxml", "line", "marcxchange".
849 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
850 does not print anything except warnings for records.
852 For yaz-marcdump, added support for MARC split into files (-s) with a given
855 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
856 spec, at http://www.loc.gov/standards/sru/record-update/
857 This has changed the binary layout of the following structs:
858 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
859 bend_update_rr . Patch by Ko van der Sloot.
861 Added GFS utility function bend_assoc_is_alive which returns 1 if
862 association is still alive (client is connected); 0 otherwise (client
863 closed connection). This allows busy servers to stop working for
866 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
867 been a separate piece of software. This version of ziffy has been modified
868 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
870 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
872 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
873 Client code may now interrogate options such as "init_opt_sort" to
874 find out whether the server claims to support various options.
876 --- 2.1.40 2006/11/27
878 Added utilities yaz_{set,get}_esn to set/get element set name from
881 Removed the build of libyazthread.la. The libyaz.so is the threaded version
882 of YAZ and has been so since YAZ 2.1.10.
884 Implemented ZOOM_record_error which returns error information for
885 record (surrogate diagnostic).
887 --- 2.1.38 2006/10/31
889 Updates for SRU Update by Ko van der Sloot:
890 1. Changed name from "operation" to "action"
891 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
892 versions in the code, marked as 'backward compatible'.
893 3. Added diagnostics for SRU Update.
895 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
897 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
899 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
901 For GFS, fixed problem with SRU diagnostic 'First record position out of
902 range' being issued for 0 hits.
904 zoomtst10 part of Windows Build.
906 --- 2.1.36 2006/10/13
908 Implemented yaz_filepath_comp which splits a path into file path
909 components (required by Zebra 2.0.3+).
911 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
912 BSD inspired license until now so this should not have any real impact on
913 anybody. See http://www.opensource.org/licenses/bsd-license.php
915 Fixed bug #687: Missing log lines.
917 Fixed bug #678: CQL to PQF translation does not preserve double-quote
920 Fixed bug #689: SRU diagnostics to be added.
922 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
923 whether a connection is idle (no more work do do).
925 --- 2.1.34 2006/10/04
927 Change type of optval from long to int for invocation of setsockopt with
928 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
930 Added support for specifying the max log file size for the Generic
931 Frontend Server. The size is given with option -r.
933 --- 2.1.32 2006/09/21
935 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
937 --- 2.1.30 2006/09/17
939 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
942 Fixed bug in Generic Frontend Server that could cause a server to stop
943 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
945 For the generic frontend server, the maximum record size is used as maximum
946 size of incoming packages (SRU + Z39.50). The value until was previously
947 only used in Z39.50 Init negotiation and, later, in a session controlled
948 sizes of records returned. This is controlled using -k option. It can be
949 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
951 --- 2.1.28 2006/09/04
953 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
956 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
958 New option for yaz-marcdump -lpos=value which allows setting a portion
959 of MARC header to a certain value.
961 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
963 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
964 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
966 --- 2.1.26 2006/08/15
968 Fixed problem with SRU mode type (soap, get, post) for yaz-client
971 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
973 --- 2.1.24 2006/08/08
975 Fixed MARC ISO2709 encoding routines to deal with character set
978 Minor changes to GFS logging. Database included in search request log
981 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
982 cached/multiple records.
984 Shared libraries are built by default on Unix+configure.
986 Changed cql2pqf transformation to use a different evaluation order. The
987 new order is: always, relation, structure, position, truncation, index
988 and relationModifier. Old order was: always, relation, relationModifier,
989 structure, index, position, truncation. Note that the the latter ones
990 override former ones for identical attributes.. The new scheme means that
991 it is possible to override any existing attribute with a relationModifier.
992 And also that it is possible to override everything for the index rule
993 (except the ones listed in relationModifier). No order is perfect but this
994 one, we believe, covers more real cases.. The "always" should have been
995 called "default", since the attributes there can be overridden with all
998 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
999 compilation phase, but also for yaz-config --cflags output. This allows
1000 us to have public headers with Libxml2 stuff in them . It should also,
1001 eventually, make Libxml2 checks redundant in packages using YAZ, such
1004 --- 2.1.22 2006/06/15
1006 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1007 stored in uri, message and details.. Previously diagnostics were stored
1008 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1009 compatibility.. but he's probably the only one affected, so.
1011 Added support for CCL, compiled on the client side, in ZOOM-C. This
1012 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1013 input; the resulting query objects can be used for for searching with
1014 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1016 YAZ' configure searches for OpenSSL by default.
1018 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1019 SL_CTX_use_certificate_file. See
1020 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1021 for more info. Thanks to Ko van der Sloot.
1023 --- 2.1.20 2006/06/02
1025 Bug #600: SRU GET, POST support for yaz-client. Introduced
1026 command 'sru' which selects method SOAP/GET/POST.
1028 Allow missingValueAction to be specified for the sortspec string -
1029 function yaz_sort_spec. By default, the missing value action is null.
1030 Use ! to specify "abort". Use = followed by stringvalue to specify default
1033 Ensured that Present-handler (if defined) is called in GFS before any call to
1034 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1035 searchRetrieve requests.
1037 Documentation for YAZ is now based on the Docbook XML/XSLT using
1038 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1039 is no longer depending on jade/openjade or docbook-to-man scripts.
1040 PDF is no longer part of the distribution - but can optionally be
1041 made using DSSSL/jadetex or FOP.
1043 Added retrieval handling support in Generic Frontend Server to support
1044 conversion between MARC/XML as well as XSLTtransforms. See
1045 etc/yazgfs.xml for an example.
1047 Added Authentication support to Generic Frontend Server in SRU
1048 mode. Authentication using HTTP Basic is supported, as is the use
1049 of 'x-username' and 'x-password' parameters in the request itself.
1051 Added support for a new character set MARC8s identical to MARC8 except
1052 that it converts combined characters to single Unicode characters in the
1053 Latin-1 range (when possible).
1055 --- 2.1.18 2006/04/24
1057 ASN.1 compiler 0.4: generates brief Doxygen file header for
1058 generated .h/.c files.
1060 Utility yaz_iconv now supports conversion to MARC-8.
1062 New facilities for the MARC module. The reading - and writing of
1063 content are separate methods for the yaz_marc_t handle. The following
1064 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1065 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1066 format). Write functions have prefix yaz_marc_write_.. The existing
1067 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1068 available. Removed support for OAI-MARC and simplexml (not the
1069 simplexml from PHP5).
1071 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1072 to be returned for this connection.
1074 --- 2.1.16 2006/03/31
1076 Allow multiple languages and charsets to be specified with
1077 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1078 negcharset iso-8859-1,utf-8
1080 Translation of proximity nodes from CQL into PQF now works.
1082 Moved to automake 1.8, 1.9.
1084 Added function yaz_log_set_handler which allows a log handler to be
1085 installed. This handler will be called for all log messages. Output
1086 to file is also produced; but that can be disabled by passing NULL
1087 fname to yaz_log_init_file.
1089 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1091 For SRW (including GFS), accept application/soap+xml as content-type
1094 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1095 produces NO stylesheet reference even if a default stylesheet is specified
1098 --- 2.1.14 2006/03/14
1100 Updated Windows package to include yazd.dll + yazd.lib for the
1101 Development component.
1103 If the environment variable YAZ_LOG is set, then it is used as a
1104 string indicating the default level of logging to use if not
1105 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1106 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1107 used as before. So, for example, to omit warnings from YAZ logging,
1108 export YAZ_LOG=-warn
1110 cql_transform() now map structure and other attributes before indexes,
1111 so that index-specific structures and other attributes can override
1112 defaults. So now a combination of mapping specifications such as:
1114 index.dc.date = 1=date-modified 4=5
1115 does the right thing.
1117 cql_transform() now also respects the "always" mapping specification,
1118 which establishes an initial set of attributes to be used for all
1119 terms except where overridden by more specific attributes associated
1120 with the index, relation or modifier.
1122 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1123 which mode to use; one of "post", "get" or "soap" (SRW, default).
1125 Fixes for yaz_iconv routines: changed trie-based character set conversions
1126 to use only non-negative values for bit fields due to Sun's C compiler not
1127 supporting negative values.
1129 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1130 sequences where not read correctly. Fix by Rustam Usmanov.
1132 Updated win/makefile to use options, settings which makes things
1133 compile with VS C 2005.
1135 --- 2.1.12 2006/02/01
1137 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1139 In ZOOM socket code, use select instead of poll on MacOSX.
1141 ZOOM-C now support client-side compilation of CQL into RPN that is
1142 sent to the server, enabling CQL to be used against all Z39.50
1143 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1144 ZOOM_query object, and submit it using ZOOM_connection_search().
1145 The CQL-to-RPN translation uses a configuration file, the name of
1146 which must be specified in the Connection's "cqlfile" option.
1148 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1149 function, which takes as its start-term parameter a ZOOM_query object
1150 (which may have had either CQL or RPN set into it).
1153 --- 2.1.10 2005/11/29
1155 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1156 GFS to support this as well. Backend handler, bend_srw_update, does the
1157 update work. Code contributed by Ko van der Sloot.
1159 Allow retrieval of Search Result-1 information in ZOOM by the use of
1160 options that are attached to a result set. ZOOM documentation updated
1163 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1164 UTF-8 conversion. Patch by Raj Patel.
1166 Added option -m to GFS to control formatting of timestamps in log file.
1168 Added 'exit' as synonym for 'quit' in yaz-client
1170 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1171 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1172 for the new members. Patch by Ko van der Sloot.
1174 Added support for SRU POST. It is supported for content-type
1175 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1177 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1178 Instead make the library libyaz.la multi-threaded. Threading as a whole
1179 can still be disabled by configure option --disable-threads. Previosly,
1180 with older GLIBCs there were problems with MT libs under Apache. This
1181 has now been fixed a long time ago.
1183 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1186 CQL module modified to be case insensitive for relations/indexes/operations.
1188 Fixed bug in CQL transform code: incorrect value relationModifieder
1191 Added 'show all' command for yaz-client which retrieves all results
1194 Added new yaz-client, xmles, which takes a (private) OID and
1195 a document to be sent as an extended service request.
1197 Describe new yaz-client commands wait_response and set_auto_wait.
1199 Increase TCP/IP listener backlog from 3 (which I am guessing was
1200 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1201 that the socket will queue as many incoming connections as it's able
1202 to handle ongoing connections. In other words, it will never now
1203 refuse a connection that it would be able to handle merely because
1204 it's not got around to accepting() enough of the pending connections
1205 yet. This is the behaviour anyway under Linux, where the listen()
1206 argument is ignored; but not under BSD and on systems such as
1207 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1208 YAZ-based servers should now be uniform across operating systems in
1211 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1212 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1213 This allows yaz-marcdump to read large MARC batches (>2 GB).
1215 Modified all YAZ source files - except the source which is auto-generated
1216 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1219 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1220 corresponding to the existing *_setl() function. These allow option
1221 values containing arbitrary valuues.
1223 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1224 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1225 except that it returns an indicator of whether or not the sort
1226 criterion was accepted (0 for OK, -1 for invalid).
1228 --- 2.1.8 2005/06/07
1230 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1231 MARC output rather than returning "new" buffer.
1233 yaz-client warns about unknown init options.
1235 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1237 --- 2.1.6 2005/05/24
1239 Added support for SRW sort in Generic Frontend Server. Patch
1240 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1241 sortKeys - or NULL if none is provided.
1243 Fixed bug #307: It was impossible to specify indefinite/no timeout
1244 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1247 Added support for multiple languages and charsets to be specified in
1248 ZOOM. Each charset/language is separated by a blank. If negotiation is
1249 in effect in init-response, Option
1250 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1251 Code based on patch by Vasiliy Osadchuk.
1253 Fixed bug #306: infinite recursion that occurred when calling
1254 yaz_log_level_init as the first call (before other log level or
1257 Fixed bug in scan handling in front end server: if preferred-Position-In-
1258 Response was non-present, a NULL pointer referece was performed.
1260 --- 2.1.4 2005/04/26
1262 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1263 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1264 now defined for all those error codes. So instead of putting 109 in
1265 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1266 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1268 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1271 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1273 Program yaz-client now exits and produces an error message if multiple
1274 Z39.50 servers are specified on the command line (none or one allowed
1277 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1280 --- 2.1.2 2005/03/16
1282 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1284 Fixed bug #272: Preserve spacing for CCL terms.
1286 --- 2.1.0 2005/03/14
1288 Added support for virtual hosts and multiple backend servers for
1289 the YAZ frontend server. The configution is XML based and
1290 support specificition of CQL to RPN mappings and explain information.
1291 See section "Virtual Hosts" in the YAZ manual.
1293 Extended OPAC display utility. OPAC display utility renders
1294 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1295 to supplement yaz_marc_decode_wrbuf.
1297 Fixed a bug in MARC decoder that could caused it to crash for some
1298 invalid MARC records. More diagnostics and warnings where added in
1299 XML output (warnings, etc are stored in comments).
1301 --- 2.0.34 2005/02/08
1303 Fixes for UNIX domain sockets. Bug #261.
1305 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1307 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1308 Added yaz_marc_subfield_str which defines subfield lead string which is
1309 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1310 yaz_marc_endline_str which defines end of fields string used in
1311 YAZ_MARC_LINE format. Default string is newline.
1313 Experimental support for MarcXChange. This format can be produced
1314 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1315 http://www.bs.dk/standards/MarcXchange.xsd
1317 Added yaz-client commands scansize that sets maximum number of
1318 entries to be returned by scan.
1320 --- 2.0.32 2005/01/11
1322 Added support for SRW scan in yaz-client and Generic Frontend Server.
1324 * Added whereInList member to SRW Scan Term.
1326 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1328 Fixed NMEM system to return aligned blocks on the smallest boundaries
1329 that are suitably aligned for all possible types on the particular
1330 architecture YAZ is being built for.
1332 --- 2.0.30 2005/01/04
1334 Fixed numerious warnings that was issued with newer versions of GCC.
1336 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1337 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1340 Make YAZ Generic Frontend Server slightly faster.
1342 Enhance (and reduce) logging for Generic Frontend Server.
1344 Revert YAZ log system so that it flushes every write operation
1345 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1347 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1348 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1349 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1350 will effectively disable old definitions.
1352 --- 2.0.28 2004/11/09
1354 Added yaz_log_time_format which specifies log format using
1357 Added yaz_log_module_level which returns mask for a module. Value
1358 is non-zero mask a if module is enabled; zero if disabled.
1360 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1361 in include/yaz/cql.h.
1363 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1365 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1367 Fixed bug #172: RPM builds does not enable SSL.
1369 Doxyfile.in part of dist. Doxyfile generated by configure.
1371 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1372 are given and the corresponding component does not exist.
1374 Extend CCL documentation in YAZ reference. Describe r=r.
1376 --- 2.0.26 2004/10/01
1378 Fixed MARC->MARCXML conversion to properly deal with
1379 fields, subfields, indicators having non-ASCII characters.
1381 Fixed MARC->MARCXML conversion so that ASCII control characters
1382 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1385 Added YAZ GFS support for conversion from Z39.50 surrogate
1386 diagnostics to SRW surrogate diagnostics.
1388 Bug fix: YAZ GFS did not return schema in explainResponse.
1390 --- 2.0.25 2004/09/30
1392 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1393 now converts recordSchema to elementSetName as well as schema URI.
1395 Fixed bug in COMSTACK that prevented HTTP request packages from being
1398 --- 2.0.24 2004/09/29
1400 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1401 does not require white-space before and after the dash in a range, e.g.
1402 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1405 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1406 due to new GCC removing "redundant" code.
1408 Added yaz-client commands scanpos and scanstep that sets preferred
1409 position and step-size for scan.
1411 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1413 Added CCL utility ccl_qual_buf which parses one or more CCL
1414 spec lines in a buffer.
1416 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1417 of name and value - ignoring empty lines and comments.
1419 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1421 Added odr_get_element_path which returns current element path for an
1422 ODR handle. This utility is useful in error handling or user-defined
1425 Added ODR_PRINT utility odr_set_stream which is is a more generic
1426 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1427 to a write function and pointer to close function. The close function - if
1428 non-NULL - will be called during odr_destroy.
1430 Fixed bug in CCL parser where truncation char was not removed from
1431 right side when truncation=both was in effect.
1433 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1436 --- 2.0.23 2004/08/11
1438 Fix buffer overrun in CQL parser when dealing with proximity (%).
1440 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1441 to UTF-8/UCS conversion is now only based on codetables.xml.
1443 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1445 --- 2.0.22 2004/08/06
1447 Add support for more "commit changes" in ZOOM (uses Extended Services).
1449 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1452 Yet another small fix for configure of SSL.
1454 --- 2.0.21 2004/05/14
1456 Fix SSL libs for configure when --with-openssl=DIR is given.
1458 --- 2.0.20 2004/05/10
1460 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1462 SSL comstack now uses yaz.pem certificate file on server side
1463 by default. Certificate filename can be configured by calling
1464 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1466 Fix bug regarding multiple calls to ZOOM_connection_connect.
1468 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1470 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1471 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1473 ZOOM now allows inspection of X509 peer certificate for verification.
1474 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1476 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1477 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1478 as "modular" but it simplifies things.
1480 Added cs_get_peer_certificate to that returns peer X509 PEM.
1482 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1483 NULL if SSL is unavailable.
1485 Documentation about MARC decoding tools.
1487 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1489 --- 2.0.19 2004/03/30
1491 Rename CHANGELOG to NEWS to follow GNU style packing.
1493 Fix bug with missing initialization of member in init_diagnostics.
1494 This bug affects threaded version of GFS server.
1496 --- 2.0.18 2004/03/20
1498 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1501 Ensure zlib.dll is packed with Windows install.
1503 --- 2.0.17 2004/03/17
1505 Fix encoding of xsd:string to use text instead of CDATA.
1507 Fix endless loop in CQL parser with unbalanced ".
1509 Use a more compact way to store MARC-8 conversion tables.
1511 --- 2.0.16 2004/03/16 Debian only
1513 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1516 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1521 --- 2.0.15 2004/03/01
1523 Another fix for decoding of XML packed records.
1525 --- 2.0.14 2004/02/25
1527 Fixes for Chunked encoding. White space not ignored after length spec.
1529 Update NS and use default NS for SRW diagnostic elements.
1531 --- 2.0.13 2004/02/23
1533 Implement ZOOM_resultset_cache_reset which resets record cache.
1535 Implement ZOOM_resultset_sort which sorts a result set.
1537 Implement chunked HTTP transfer.
1539 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1541 --- 2.0.12 2004/02/16
1543 Added member 'schema' to bend_explain_rr structure so that backend
1544 can specify explain record identifier. Defaults to Zeerex 2.0.
1546 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1548 --- 2.0.11 2004/02/16
1550 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1553 Added init command for yaz-client which sends "extra" init request.
1555 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1556 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1558 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1560 Make ZOOM error code for "invalid query".
1562 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1564 --- 2.0.10 2004/02/05
1566 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1569 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1571 Added option -p <file> to make Generic Frontend Server to write PID file.
1573 Added option -D to put Generic Frontend Server in background on its own.
1575 Make ZOOM C recognize option "password". If unset, "pass" is used
1576 (for backwards compatibility).
1578 Fixed a bug in Generic Frontend Server that could make it crash if a
1579 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1582 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1583 Must be issued before open, in order to be in effect.
1585 --- 2.0.9-6 2004/01/12 Debian/Windows
1587 Make the SRU server more picky WRT unknown params, etc.
1589 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1591 New YAZ client command, options, that sets Z39.50 options.
1593 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1594 options from a string of tokens (one token for each option bit).
1596 Update SRW diagnostic code messages.
1598 --- 2.0.9-5 2004/01/07 Debian/Windows
1600 Handle user defined stylesheet for SRW/SRU.
1602 --- 2.0.9-4 2004/01/06 Debian/Windows
1604 Fix bug in decoding of Content-Length.
1606 --- 2.0.9-3 2004/01/06 Debian/Windows
1608 Fix a bug with decoding of XML packed records.
1610 --- 2.0.9-2 2004/01/05 Debian only
1612 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1614 Fix bug in SRW/SRU diagnostics decoding.
1616 --- 2.0.9 2004/01/05
1618 Fixed bug in Generic Frontend Server which could drop records exceeding
1619 preferred message size. Reported and fixed by Irina Dijour.
1621 Fixed calculation of package size for structured records in Generic
1622 Frontend Server. Reported and fixed by Irina Dijour.
1624 Fixed namespace for SRW/SRU diagnostics.
1626 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1628 --- 2.0.8 2003/12/22
1630 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1631 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1634 CQL changes to reflect recent changes to the specification:
1635 * Documentation talks about context sets instead of index sets.
1636 * Documentation talks about indexes instead of qualifiers.
1637 * The CQL-to-PQF transformer's configuration file now uses
1638 "index.set.name = <attributes>" instead of the old form
1639 "qualifier.set.name = <attributes>". (Both forms are still
1640 understood but the latter is deprecated.)
1641 * CQL terms with no explicit index specified are now interpreted as
1642 cql.serverChoice instead of srw.serverChoice (which of course
1643 behaves exactly the same.)
1645 --- 2.0.7 2003/12/16
1647 MARC conversion can now generate ISO2709 output in another
1648 character set. yaz-marcdump uses this facility if you invoke it
1651 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1652 functions from there can be used from C++.
1654 --- 2.0.6 2003/12/04
1656 Frontend server now transfers memory from decoded packages to stream
1659 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1660 references to show up.
1662 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1663 the ZOOM Abstract API. The older names for the same options are still
1664 also supported for the benefit of old applications.
1666 ZOOM-C supports "implementationId" and "implementationVersion" options
1667 to go along with "implementationName". These allow the user code to
1668 specify identification strings to be sent to servers.
1669 Add OID for the new ExtLite attribute set.
1671 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1672 as requested/supplid by Ere Maijala <ere@atp.fi>
1674 For generic frontend server, reverse the order of
1675 "toolkit-supplied / application-supplied" strings sent as implementationId,
1676 Name and Version. Also, remove the spaces around the slash. This brings
1677 the GFS in line with the behaviour of ZOOM-C on the client side.
1679 Add function ZOOM_scanset_display_term.
1681 yaz-client shows scan displayTerm if present.
1683 Utility yaz-iconv is now installed by default along with the man page
1686 Extend configure check for OpenSSL to use pkg-config where available (such
1689 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1690 server to specify uid/gid/mask for socket using the format
1691 unix:[user=uid,][group=gid,][umask=mask,]file=path
1692 If file= is omitted the existing format is assumed, e.g.
1694 in which case the mask is 0666 (rw for everybody).
1696 Major restructure of YAZ source. All source in libyaz is in src directory.
1697 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1698 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1700 Added man page for utility yaz-marcdump (used to be called marcdump).
1701 yaz-marcdump is installed by 'make install'.
1703 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1704 of incoming package failed.
1706 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1708 Change prototype of odr_perror: add const to message string.
1710 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1712 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1713 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1714 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1715 DNS lookup. There should not be any compatibility problems with this
1716 assuming that blocking=1 or 0 is used.
1718 Fix bad reference in UNIX comstack in function cs_addrstr.
1720 Fix for compilation on AIX.
1722 The generic front-end server (server/seshigh.c) now supports returning
1723 Init diagnostics to the client in User-information-field, in
1724 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1727 --- 2.0.4 2003/09/04
1729 Allow any CQL relation (not just all,any,exact,scr).
1731 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1732 that features the same UI.
1734 Implemented command update0 in YAZ client which is equivalent to
1735 update but uses old of Ext Update ASN.1.
1737 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1738 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1739 Previously no OID was used for this info.
1741 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1742 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1743 returns 'malformed search term' otherwise.
1745 SortResponse member resultCount now set to NULL in sort handler of
1748 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1751 Add three new utility functions for translating OIDs between various
1752 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1753 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1754 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1755 char *oid_to_dotstring(const int *oid, char *oidbuf);
1756 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1758 Reverted modifications for ES Update definition for z_IU0Update
1759 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1760 is back to YAZ 2.0.2.
1762 String value attributes for CCL parser.
1764 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1765 which their FirstSearch server returns in Init responses, sometimes
1766 carrying useful diagnostic information when Init fails. This has the
1767 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1768 "z39.50/oclcui.asn", where its definition is somewhat different from
1769 what OCLC document on their web-site, as required to interoperate with
1772 Support for anonymous authentication in yaz-client. Use the command
1775 * Fix the OID of the Index Data-local "admin" Extended Service from
1776 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1777 the 1000, which indicates a locally-defined OID, was a mistake.
1779 --- 2.0.3 2003/06/20
1781 Fix CCL directive @case handling so that it affects string match for
1782 both CCL keywords and qualifiers.
1784 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1785 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1786 Decoder has been updated with ASN.1 changes as listed in
1787 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1788 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1789 z_IUUpdate, remains unchanged.
1791 ZOOM_record_get may now return a record in a specific character set.
1792 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1793 "from" is the character set of record as returned by target. "to" is
1794 the character set to be returned. If omitted, "to" is UTF-8.
1796 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1798 New ODR utility, odr_getelement, which returns name of element for
1799 which encoding/decoding failed.
1801 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1802 in cases where a required element was omitted.
1804 Bug fix: some MARC8 sequences were not converted.
1806 New ZOOM option "step" which specifies number of records to be
1807 retrieved in one chunk. Used in conjunction with "start" and "count".
1809 SRW support for yaz-client. Use scheme http: to use it, e.g.
1812 yaz-client no longer does (un)intelligent character set conversions
1813 by default. Can be enabled with charset and marc_charset commands.
1815 xmalloc trace fix for 64-bit systems such as DEC alpha.
1817 Solaris 2.6 compile fix.
1819 New function, cql_strerror() translates SRW error codes, as returned
1820 by cql_transform_error(), into human-readable English strings. Used
1821 in yaz-client diagnostics when appropriate.
1823 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1824 converts it into a type-1 query which is sent to the server. This
1825 makes CQL available for use with all Z-servers, as opposed to the tiny
1826 minority that can handle CQL queries themselves.
1828 --- 2.0.2 2003/04/28
1830 New Debian package layout similar to the Redhat Package layout.
1832 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1833 and search result respectively.
1835 --- 2.0.1 2003/04/25
1837 Redhat package is now several packages: libyaz (runtime libraries),
1838 libyaz-devel (development and documentation, and yaz (utility programs).
1839 Package spec file by Morten Bogeskov.
1841 New member 'schema' in struct bend_fetch_rr which the name of requested
1842 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1843 handler MAY set this to reflect the schema of the returned record.
1845 New member 'display_term' in struct scan_entry. GFS now sets member entries
1846 and allocates scan entries to be filled by user scan handler. In previous
1847 version, entries member was allocated by the scan handler. That still works,
1848 but the GFS will ignore member display_term - assuming it was NOT set by
1849 the handler. The fact that the GFS now allocates the entries both allows
1850 for new members and makes a scan handler easier to write.
1852 Fix CQL lex buffer overflow.
1854 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1855 SRU default recordPacking is string.
1857 SRU protocol support for frontend server.
1859 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1861 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1863 Added scan for the ZOOM shell (zoomsh).
1867 * String Identifers for Schemas (Amendment 5).
1868 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1869 Old definition for schema
1870 Odr_oid *schema; /* OPT */
1875 Z_InternationalString *uri;
1876 #define Z_Schema_oid 1
1877 #define Z_Schema_uri 2
1880 * resultCount parameter to Sort Response (Amendment 1).
1881 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1883 Support for SRW 1.0 over HTTP. This is an optional feature and
1884 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1887 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1888 on the same port. SRW SearchRetrieveRequests are mapped
1889 to bend_init,bend_search,bend_fetch,bend_close.
1891 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1893 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1894 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1896 ZOOM connections are SRW based if schem http is used for hostname
1897 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1898 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1900 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1901 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1902 distance=n, order=true/false, relation=le, prox unit=word. If
1903 n is omitted, distance 1 is used.
1905 Fixed problem with C compiler include path in wrong order.
1907 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1908 on Solaris. Patch from Ko van der Sloot.
1910 New MARC decode API. All new functions operate on a yaz_marc_t
1911 handle. The most important new functions are: yaz_marc_create,
1912 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1913 decode and destroy respectively. Decoder can produce formats
1914 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1915 include/yaz/marcdisp.h.
1917 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1918 to UTF-8, UCS-32, wchar_t or Latin-1.
1920 * Prototypes for yaz_iconv_-functions moved to separate header
1921 include/yaz/yaz-iconv.h.
1923 Make a few private functions 'static' in unix.c. This prevents
1924 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1926 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1927 are set when Init Response is received.
1929 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1930 but returns diagnostic set as well.
1932 New function yaz_strerror which is a portable wrapper for
1933 strerror/strerror_r/GetLastMessage.
1935 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1936 is returned for MARC. If type is "oai", then OAI MARC is returned.
1938 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1941 --- 1.9.2 2002/11/26
1943 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1945 Fix bad race conditions on SIGTERM and terminate gracefully in
1948 Move retrieval (data1) module to Zebra since nobody seems to be
1951 Add GRS-1 render for ZOOM using same format as yaz-client.
1953 --- 1.9.1 2002/10/05
1955 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1957 Fix broken ESpec handling in data1 module.
1959 SGML reader parses comments and makes them part of the data1 tree.
1961 Added several type casts so that YAZ compiles as C++ code.
1963 ZOOM didn't handle PDU encoding failures properly.
1965 Added more Bib-1 diagnostics (approved extensions).
1967 GNU configure: better check for iconv.
1969 More portable use of accept, getpeername. Check for socklen_t. Use
1970 int/size_t if socklen_t is not defined.
1974 PQF parser rejects bad queries - including those with extra
1975 characters in them. PQF parser used to silently ignore that.
1976 Cleaner API for PQF added, which allows you to get detailed
1977 error information for bad queries (see yaz/pquery.h).
1979 Fixed bug in ZOOM_record_get for type "database".
1981 Implemented mini iconv library supporting conversions between
1982 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1984 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1986 --- 1.8.9 2002/08/20
1988 Fixed ZOOM C record cache so that preferredRecordSyntax and
1989 elementSetName is used to check for already fetched records.
1991 --- 1.8.8 2002/08/02
1993 Added three members in bend_initrequest structure to facilitate
1994 character set negotiation.
1996 Fixed a bug in frontend server that could cause indefinite
1997 loops under rare conditions.
1999 Revised character set utilities (charneg.h) so that encoding
2000 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2002 For PQF, directive @term <type> sets term type for Scan/Search.
2003 Here <type> is general, string, numeric, null. The term type
2004 is inherited - just like @attr.
2006 New call odr_set_charset that sets character set conversion for
2007 international-strings on a ODR stream. Prototype is:
2008 int odr_set_charset(ODR o, const char *to, const char *from);
2009 The InternationalString is still represented as C string in YAZ
2010 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2011 won't). On the protocol level, you can use any encoding.
2013 Support for UNIX sockets in ZOOM.
2015 Solaris recv sometimes returns errno == ENOENT. It is treated as
2016 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2018 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2019 both client and server. Code by Morten Bogeskov.
2021 --- 1.8.7 2002/05/22
2023 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2024 that they can be used directly from Visual Basic. You must recompile
2025 your windows APP if you're using ZOOM.
2027 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2028 Commands "lang" and "charset" sets language and character set respectively.
2029 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2030 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2032 Attributes from multiple CCL fields may be OR'ed rather than merged
2033 using directive "@field or". Fields are still merged by default -
2034 equivalent to "@field merge".
2036 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2039 Fixed bug in zget for parameter ExtendedServicesResponse.
2043 --- 1.8.6 2002/03/25
2045 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2047 Client displays USR.1:SearchResult-1 (hits per term).
2049 Additional Search Info for search in Generic Frontend Server.
2051 Fixed CCL parsing of "field=s".
2053 WIN32 installer - using the excellent NSIS software from nullsoft.
2055 Fixed CCL parsing of "field = - <number>".
2057 Added function yaz_marc_decode that decodes MARC for line mode
2058 display or XML (similar to that used by JZKit).
2060 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2061 Z39.50. But ISO/ILL was, however.
2063 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2064 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2066 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2067 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2069 --- 1.8.5 2002/02/03
2071 New YAZ client features: Command completion and new commands:
2072 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2073 Code provided by Jacob Poulsen.
2075 New call oid_trav, that visits all registered OIDs via callback.
2077 Function ZOOM_record_get now returns const char pointer rather than
2078 void pointer. It saves a lot of type casts.
2080 For YAZ client, command "auth" now allows you to set authentication
2081 in IdPass style. It is enabled when three tokens are given - order
2082 is user, group and password.
2084 Fix memory leaks in MARC record handling for ZOOM.
2086 New option for YAZ client, -k <kilobytes> that sets
2087 maximum record size. Similar to -k option for generic frontend
2088 server and yaz-ztest.
2090 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2092 Prefix query parser reports "fail" when bad attribute set is given.
2094 Fix in MARC decoder. Proximity logging. Fix for attribute set
2095 in scan handler for server. Patches by Shigeru Ishida.
2097 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2100 Configure option --with-openssl=<dir> now works when a directory is
2101 specified. Patch provided by Morten Bogeskov.
2103 New option for YAZ client, -u <auth>, that sets authentication.
2105 ZOOM fix: error information was sometimes "missing", since error
2106 was cleared/reset too when it shouldn't.
2108 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2110 --- 1.8.4 2002/01/04
2112 Scan for ZOOM API. New object ZOOM_scanset. New functions
2113 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2114 ZOOM_scanset_destroy.
2116 New ZOOM function, ZOOM_connection_last_event, that returns type
2117 of last event (such as "receive data", "send data", "apdu received",
2120 New ZOOM option, schema, that specifies schema for retrieval.
2122 New CCL feature. Qualifiers can be aliases for one or more
2123 other qualifiers (if more than one is given, OR is used).
2125 ZOOM uses named result sets if target supports it.
2127 Two new YAZ client commands: . (dot, which sources a script of YAZ
2128 client commands), and ! (to execute shell command.). Implemented
2131 Working on Debian packages.
2133 --- 1.8.3 2001/11/19
2135 YAZ client enables named result sets only if target supports it.
2137 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2139 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2140 with key="host" to get same result.
2142 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2143 Function Z3950_resultset_record(s) returns references to records
2144 "owned" by resultset. To become owner use Z3950_record_clone.
2146 Function z_ext_record handles Extended Services. Thanks to
2149 --- 1.8.2 2001/11/12
2151 CCL Parser fix: ignore token comma when dealing with and-lists.
2153 Documentation updates for COMSTACK.
2155 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2156 Changed prototype Z3950_records. For some functions, int parameters
2157 were changed to size_t.
2159 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2162 New MARC decode/display function, marc_display_exl, which properly rejects
2163 non-ISO2709 records. YAZ client uses it.
2165 --- 1.8.1 2001/10/29
2167 Fix bug: local attribute set wasn't set correctly in PQF strings.
2171 * Old Z39.50 codecs no longer supported.
2173 Added ZOOM C binding. See http://zoom.z3950.org/
2175 Renamed states for COMSTACKs to avoid confusion with events.
2177 Implemented cs_look and proper cs_rcvconnect.
2179 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2181 Configure detects POSIX threads on OpenBSD.
2183 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2184 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2186 When error is returned from present handler, non-surrogate diagnostic
2187 is returned in present response (and fetch handler is no longer called).
2189 * Minor adjustments to pquery parser (PQF). Token characters may be
2190 escaped by using backslash (C-style).
2192 PQF parser allows string attribute values to be specified. For @attr,
2193 non-numeric characters after the equal-sign are treated as strings
2194 (e.g. @attr 9=title).
2196 CCL trunction character may be defined (@truncation in file)
2198 * function zget_ExtendedServicesRequest sets waitAction to
2199 waitIfPossible (was wait).
2201 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2204 CCL operator names may be set in field definition files (CCL_bibset).
2205 See ccl/bib1 for an example.
2207 Fixes in ASN.1 compiler for C++ compatibility.
2209 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2210 and "op_or" to avoid conflict with C++.
2212 Fixed problem with GNU readline detection on Redhat 7.0.
2214 Added step-size for Scan backend handler.
2216 Fixed bug that made the frontend server crash when no attribute
2217 set was specified for scan.
2219 Front-end server automatically switches to original working directory
2220 when installed as an NT service. Previously -w had to be specified to
2223 Added extended attributes for retrieval module (data1), so that data1
2224 records carry d1_readXML/SGML attributes. d1_read also supports
2225 null-data rules ( <tag/>)
2227 On UNIX when POSIX threads are available, a separate library libyazthread
2228 is created. Programmers should link with that library and the yaz library
2229 when using threads. The reason for the split was that some applications
2230 on Linux, such as Apache, doesn't work well when using shared objects that
2233 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2234 (or any frontend server) in SSL mode by specifying ssl: followed by
2235 address. Only tested on UNIX.
2237 Added feature for CCL module. Virtual structure s=al or s=ol generates
2238 and-list and or-list respectively instead of phrase search.
2242 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2243 log_mask_str. This was done to avoid name conflicts with other libraries
2244 (such as other PHP extensions).
2246 Added raw OID member for preferred record syntax (request_format_raw)
2247 and returned record syntax (output_format_raw) for backend fetch method.
2249 Config file yaz-config now accepts options so that it returns specific
2250 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2252 Shared library support for UNIX using GNU libtool.
2254 * Modified backend interface. Request/Response struct's replaced by
2255 one read/write C struct. For example bend_fetchrequest and
2256 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2257 Every handler - even search has to be registered in bend_init
2258 handler. This means that the YAZ library no longer refers to
2259 external functions and it makes it possible to make the whole
2260 thing a single DLL/SO.
2262 Added Segment handler for backend server.
2264 Added Zmbol/Zebra administrative functions to YAZ client.
2266 Threaded frontend server on UNIX (when POSIX Threads are available).
2267 Starting the server with option -T enables multi-threading.
2271 Added configure option --enable-comp/disable-comp to control use
2272 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2273 located in sub directory asn.
2275 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2276 in ${exec_prefix}/bin along with the other programs yaz-client and
2279 GNU automake used to maintain makefiles.
2281 Added several OID's.
2283 Changed retrieval module so that we can load records with no abstract
2284 syntax defined. Tagpaths in these records are fully composed of string
2287 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2291 On UNIX, the generated makefile now supports a proper 'make install'.
2292 The prefix can be set via GNU configure to set the install location
2293 (default is /usr/local).
2295 * YAZ programs client and ztest were renamed to yaz-client and
2296 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2297 locations, such as /usr/bin,/usr/local/bin,etc.
2299 * YAZ Header files were moved from include to include/yaz. YAZ Header
2300 files are referred to as include <yaz/log.h> rather than <log.h>.
2301 The YAZ include path (-I ..) is therefore the same as before. Programmers
2302 should update their #include statements or use -Ipath/include/yaz
2303 instead. The main motivation for doing this change is that YAZ header files
2304 can be installed in "standard" locations /usr/include,/usr/local/include
2305 without introducing conflicts, since ALL YAZ header files are stored
2306 in subdirectory yaz (under /usr/include for example).
2308 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2309 rather than project/workspace files. We switched because project files
2310 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2313 Changed name of logging function, logf, to yaz_log, to prevent name
2314 clash with some math-log functions. The YAZ header log.h defines logf
2315 to yaz_log (#define) so there should be no incompatibilities by this
2318 Added bend_start/bend_stop handlers for server. These handler are
2319 called on start/stop of server. For windows they are called whenever
2320 a service is started/stopped.
2322 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2323 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2324 in util/yc.tcl. The auto-generated C code structures are, in a few
2325 cases, incompatible with the old decoders. There are differences in the
2326 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2327 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2328 The preprocessor variable ASN_COMPILED is defined when the compiled
2329 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2330 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2331 wish to use the old encoders/decoders you can specify --disable-yc
2334 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2335 version so that it supports both new - and old version of DB Update
2337 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2338 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2339 change. The name parameter can be set to 0 in which no name is specified
2340 for the construction. The macros odr_implicit and odr_explicit sets name
2341 parameter to zero for the construction involved. New macros
2342 odr_implicit_tag and odr_explicit_tag are similar to the others,
2343 except that a name parameter is added. For programmers' that don't use
2344 ODR they probably only need to change the call to z_APDU and z_External.
2346 Added access control facility by interfacing the TCP wrapper library.
2347 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2348 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2349 name of the daemon and enables the access control as specified in
2350 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2352 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2353 den Dool <H.M.vdnDool@kub.nl>.
2355 Added reference ID parameter to most functions in server API - refer
2356 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2358 Changed name of ccl library to libccl.a (was ccl.a).
2360 Fixed bug in decoder for Explain (Category TargetInfo).
2362 Added support for GNU readline in client. Thanks to Jacob Poulsen
2363 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2365 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2366 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2367 IMPLEMENTATION! This change was made to the development version before
2368 the ZIG decided to retract the amendment. If any users MUST be
2369 compatible with the original Update definition, PLEASE CONTACT US, and
2370 we will include a separate definition corresponding to the old Update
2371 ES. Note that because of the change to the ASN.1 of the
2372 TaskPackageRecordStructure we cannot define a single structure that
2373 will support both versions.
2375 * Added const modifier to buffer parameter for some ODR/BER encoding
2376 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2377 completeWAIS, odr_dumpBER.
2379 Fixed bug in client.c which caused a crash when a scanResponse didn't
2380 contain positionOfTerm.
2382 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2383 * will cause an error in a client if a non-YAZ target sends both a
2384 * list of Scan entries and non-surrogate diagnostics.
2386 Retrieval module enhancements. Tag sets may be typed in the reference
2387 to it. From the .abs-file the "tagset" directive takes a third optional
2388 integer type for the tag set referenced. From a .tag-file the "include"
2389 directive takes a third optional type as well. The old "type" directive
2390 in the tag set itself is still recognized but acts as the default type
2393 Backend interface change. Individual Scan terms returned from bend_scan
2394 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2395 in include/backend.h.
2397 Retrieval module enhancements. Multiple tag sets and attribute sets may
2398 be specified in abstract syntax specs. Revised the error/warning for
2399 logging messages reported by the retrieval module when reading the
2402 Object Identifier system (oid_..) changed. The API is backwards
2403 compatible but the oid-routines now allocates new OID's when needed.
2404 Raw OID's may be specified in oid_getvalbyname.
2406 YAZ now uses GNU configure to generate Makefile(s).
2408 * Minor changes in some of the member names of DeleteResultSetRequest and
2409 DeleteResultSetResponse. See include/proto.h.
2411 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2412 and added member 'languages' in TargetInfo (which was missing).
2414 Changed the way attribute sets are handled in the retrieval
2415 module. These are now cached, just like the abstract syntaxes
2418 Changed YAZ so that it links with compiled ASN.1.
2420 Added Explain-schema definitions and mapping routines. The following
2421 Explain categories have been implemented: AttributeDetails,
2422 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2424 Fixed minor bug in Windows version of Server Library.
2426 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2428 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2430 Added EXTERNAL: UNIverse Resource Report (non-standard).
2432 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2433 ENUMERATED and SET OF.
2435 * Added 'const' to some of the char pointer arguments for the
2436 functions, data1_read_node, data1_getelementbytagname,
2437 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2440 Fixed bug in data1_insert_taggeddata - the last_child member of
2441 parent wasn't initialised.
2443 * Changed data1_read_record and data1_read_node so that the supplied
2444 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2445 doesn't refer to any parts of the "SGML"-buffer.
2447 Fixed bug in server library (Windows version of statserv_remove).
2449 * Changed code so that it compiles as C++. The type definition
2450 of Odr_fun which is a member of Odr_arm was changed. The result is,
2451 that an explicit typecast is needed for the fun pointer when
2452 using Odr_arm - as in:
2453 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2455 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2457 Implemented the new structured date and time definition as approved
2458 by the ZIG. Added schemaId element to the specificTag in Espec-1
2459 (also approved at the last ZIG). Thanks to RVDM.
2461 Added some Object identifiers (RVDM).
2463 Changed the Update Extended Service (RVDM).
2465 Added command "refid" to client which specifies referenceId for
2466 the following requests.
2468 Implemented extended service handling for server. See ztest.c
2469 for an example as well as backend.h. New handlers are registerd
2470 in the Init handler.
2472 * Changed interface for sort in server.
2474 Added new members to statserv_options_block. It allows a server
2475 to read options from another source than just the command line. Thanks
2476 to Charles Woodfield.
2478 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2479 renamed to zboolean. Some C++ compilers complained about the name.
2481 Minor changes to gils.abs. Added index 's' (sort) on title
2482 and date/time-last-modified.
2484 --- 1.4pl2 1998/1/30
2486 Fixed bug in server library regarding inetd mode (-i). This bug
2487 was introduced by release 1.4.
2489 --- 1.4pl1 1998/1/29
2491 Added sort facility in client and backend server interface.
2493 Fixed problem with dependencies in Makefile(s).
2495 Fixed bugs for encoders/decoders of extended services and
2498 Implemented sub-tree feature for schemas. Sub-trees are
2499 referenced in *.abs-files. See explain.abs for an example
2500 of the use of this feature.
2502 Modified bib1.att; local attributes for ANY didn't include
2503 ANY itself (only affects use of the retrieval module).
2505 Fixed bug in plain SGML reader in function data1_read_node:
2506 tags with prefix "var" was incorrectly interpreted as variants.
2508 Added feature "sub-schemas" to enable references to - and definitions
2509 of - group of elements.
2511 * Removed member parent from type data1_element (in data1.h).
2513 Implemented function odr_nullval() that returns the value of
2516 * Removed member num_children from data1_node (in data1.h).
2518 Made NT service interface part of the server library. The
2519 function statserv_main uses the NT service when required and
2520 calls the statserv_start / statserv_close routines.
2522 Routine zget_SearchRequest and zget_PresentRequest fills
2523 resultSetName/Id member with "default" instead of "Default".
2525 Fixed memory leak in server. Request queue member wasn't freed.
2527 Fixed nmem_exit so that memory is freed.
2531 Revised the CCL parser utility to be thread safe.
2533 Added function, oid_ent_to_oid, to replace the function
2534 oid_getoidbyent, which is not thread safe.
2536 * Added nmem_init and nmem_exit to initialize and release
2537 NMEM resources. Function nmem_init should be called once in the
2538 initial thread before NMEM/ODR is used. statserv.c and client.c
2539 have been changed accordingly. The change was necessary to make
2540 NMEM thread safe. The NMEM memory pool is shared amongst threads
2541 in a process. Unix-based applications will still work fine without
2544 Added NT Services interface for the the Z39.50 (statserv) Server.
2545 Refer to the ztest.c source on the usage.
2547 Windows 95/NT port using MSVC5.0. Project files are included in the
2550 * Defined new 'global' handle for the retrieval (data1) system. The
2551 new handled, data1_handle, describes the state of the data1 system.
2552 This handle is passed as first argument to virtually all
2553 data1 related routines. The functions data1_create and data1_destroy
2554 creates and destroys a data1 handle respectively.
2556 Added ODR encode stream member to all backend request structures
2557 init, search, scan etc. This stream should be used to allocate all
2558 memory used for the response when thread safe operation is needed.
2560 Changed the comstack utility, cs_addstr, to be thread safe. The
2561 returned hostname string returned by the function is now part the
2564 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2565 function. The cs_straddr takes a COMSTACK handle as argument, so this
2566 function must be used after cs_create and before bind/connect.
2567 This function is thread safe.
2569 Moved test server to 'ztest' directory - generic server code still
2570 in 'server' directory.
2572 Made prefix query (pquery.c) utility thread safe.
2574 Added new function modifier YAZ_EXPORT to 'export' public DLL
2575 functions when using windows (see include/yconfig.h).
2577 Added definitions to the OID database (util/oid.c) (RVDM).
2579 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2581 Added call to ccl_rpn_delete in client program.
2583 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2584 release of RPN structure.
2586 Added support for C++, headers uses extern "C" for public definitions.
2587 With input from RVDM.
2589 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2590 Thanks to Ronald van der Meer (RVDM).
2592 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2594 Added support for private extensions to the OID database
2595 (oid_setprivateoids()). Thanks to RVDM.
2597 Added optional, physical ANY (key replication)
2599 Fixed null-reference problem in GRS-1 output filter.
2601 Proximity operator added to Prefix Query Format (PQF).
2603 In test client command "base" accepts multiple databases.
2605 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2609 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2611 Smallish bug-fixes in the new encoders/decoders (explain).
2613 Bug fixed in DeleteRequest.
2615 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2617 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2619 Added SOIF syntax (using private OID for now) to retrieval module and client.
2621 Added Update extended service.
2623 Added SearchResult-1 additional info structure.
2625 Added optional CCL (ISO8777) interpreter as separate module. Available
2628 --- 1.2 1996/6/10 (1st anniversary release)
2630 Added Summary record syntax. Lightly tested.
2632 Added OPAC record syntax. Untested.
2634 Added ResourceReport service encoders/decoders. Untested.
2636 Fixed bug in z_Unit - wrong tagging on unitSystem.
2638 Fixed bug in the DiagRecs decoder.
2640 Added options for max PDU size and session timeout to frontend-server.
2642 Added documentation of query-language parsers and other supporting utilities.
2644 [frontend-server] Added Attribute set to the bend_scanrequest API.
2646 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2647 surrogate diagnostics were generated.
2649 [retrieval] Allow multiple local values for attribute.
2651 [retrieval] Allow multiple attributes per element in .abs files. index type.
2653 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2655 --- 1.1pl2 1996/4/10
2657 Minor changes, mostly specific to Zebra's requirements (retrieval)
2661 Repaired bug in frontend server when running multiple listening
2662 endpoints in dynamic mode.
2664 z_External() now won't break if a known, ASN.1 value comes encapsulated
2665 in an octet-string. The value will pass through unmodified in an Odr_oct.
2667 Added a bit of code to the demo client to decode & display
2668 ASN.1-structured records represented in the octet-aligned branch of
2669 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2671 Added z_ext_getentbyref() to the ASN module. Doc updated.
2673 * Completed the SCAN definition in the ASN module. This may break SCAN
2674 code based on older YAZ-versions at compile-time. The fix is easy -
2677 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2678 under the SCAN definition. Remember to initialize this, server-people.
2680 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2681 that this does not extend to ODR and ASN.
2683 Comstack allows insertion of established socket (primarily for
2684 inetd-operation of servers). Doc updated.
2686 Front-end server can now start from the inetd in TCP mode. Doc
2689 --- 1.0pl4 1996/1/24
2693 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2694 the rank and record number.
2696 Adjustments to the frontend server.
2698 Fixed diagnostic BER dumper. It ignored the file argument.
2702 Various changes to retrieval module.
2704 Changed the union discriminators of the protocol files from enums to
2705 ints paired with #defines.
2707 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2710 *Changed operator in the RPN structure to 'roperator', again to avoid a
2713 Fixed problems in Explain decoders/encoders.
2715 --- 1.0pl2 1995/12/6
2717 Memory bug in log module fixed.
2719 --- 1.0pl1 1995/12/5
2721 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2723 Bug in Explain DatabaseInfo module fixed.
2725 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2729 The shift to v1.0 signals that we now consider the *core* functionality
2730 of YAZ reasonably stable (the core being more or less equivalent to
2731 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2732 tested (Explain not at all - though that will happen soonish).
2734 Minor changes to code to support Windows port.
2736 Various minor changes after we're getting to use GRS-1 & co. more.
2738 Added Espec-1 format.
2740 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2741 of the protocol and it cannot be selected when encoding (maps into 'string'
2742 when decoding). Needed to talk to some servers.
2744 Demo client can request simple element set names.
2746 Added Diagnostic Format encoders/decoders.
2748 Added simple Close handling to frontend server (no hooks for resource
2749 reporting yet), and demonstration client.
2751 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2753 --- 1.0b3 1995/08/24
2755 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2756 handled incorrectly when records were requested in the searchResponse. This
2757 will only affect you if you use the frontend-server.
2759 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2760 Test-client will ask for and print GRS1. Ztest will return dummy records
2763 Added Explain encoders/decoders to the service-level API. Untested.
2765 Added Extended Services: Item Order encoders and decoders to the Service-
2766 level API. Untested. We could use a recent copy of the pertinent bits
2767 of the ILL protocol to add those bits.
2769 Added diagnostic format 1 encoders/decoders to the service-level API.
2772 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2773 odr_cons.c, which causes a more correct output.
2775 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2776 was always set to 0 when no records were requested in the searchRequest.
2778 * Added better external-handling. This shouldn't harm old code that
2779 *encodes* externals. It can break code that looks for a
2780 'single-ASN1-type' representation, since those types that are known
2781 are now decoded immediately. Look at the SUTRS sample code in
2782 seshigh.c and client.c. Documentation updated.
2784 Handling of structured records in bend_fetchresponse. Length -1 marks
2785 structured record, type is deduced from format field.
2787 --- 1.0b2 1995/06/27
2788 Fairly quick maintenance release to add SUTRS support.
2790 Fixed handling of SUTRS records in the demonstration client.
2792 * Added format field to the bend_fetchrequest and bend_fetchresponce
2793 structures of the backend API (frontend server). When the record is
2794 returned, the value of the format field is mapped to an OID. The
2795 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2796 of the record. The special value VAL_NONE in the bend_request means
2797 that no specific format was requested by the client. Documentation
2798 updated accordingly. Test server (ztest) will return a fixed dummy
2799 SUTRS record if your client requests SUTRS.
2801 Documentation updated accordingly.
2803 You can now set external libraries and RANLIB support in the top-level
2807 First public release.
