3 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
6 yaz-marcdump reads and writes collection wrapped records.
8 Handle OPAC for record conversion module.
10 Fixes for ICU wrapper.
12 Allow ICU libs to be controlled with --with-icu .
16 Added yaz_poll which is a wrapper for select/poll. When poll is available
17 and non-buggy, it is used, by yaz_poll . This allows more than 1024
20 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
21 functionality through an XML based configuration (ICU chain). This system
22 is useful for search facilities such as Pazpar2 and Zebra that needs to
23 perform tokenization of indexed material. The ICU code in a separate
24 library libyaz3_icu.a.
26 Added HTTP tunnel facility for COMSTACK, bug #1752.
27 This is a facility that allows a Web proxy, such as squid, to tunnel
28 Z39.50 traffic. This facility is "transparent" to must applications
29 using YAZ. It's enabled by using pseudo transport connect: followed by
30 the proxy address, followed by command, then follwed by he regular
31 "virtual" addresss. For example,
32 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
34 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
38 Fixed bad memory reference in ZOOM_record - cuased by member not being
39 initialized. This was a problem only in YAZ 3.0.12.
41 Fixed bug in conversion from MARC to XML: Non-XML characters in control
42 fields were not removed.
44 Changed the way C code is generated from codetables.xml. Made a MARC-8
45 conversion trie for each characterSet section rather than codeTable.
46 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
47 of codetables.xml from Larry Dixson, LOC. Bug #1464.
51 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
52 from ZOOM_record_error).
54 ZOOM C function ZOOM_record_get returns record schema for type="schema".
56 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
58 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
60 Better SRW-to-Bib-1 diagnostic mapping.
62 ZOOM C and yaz-client announces SRU version 1.2 by default.
64 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
67 Fixed in yaz_sru_decode to allow other version than 1.1.
71 Added support for SRU scan for ZOOM.
73 Added support for the use of the older versions or Extended Service
74 Update in ZOOM. To faciliate this, an option "updateVersion" may be
75 set to the version , 1=first, 2=second, 3=third. The third version is
76 what ZOOM C has used so far. And that, obviously, is the default.
78 Added support for CCL queries in Z39.50 queries sent to the GFS (and
79 therefore in Zebra and in SimpleServer-based applications). The new
80 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
81 qualifier file used to transform incoming CCL queries into Type-1 RPN,
82 which is passed into the back-end search callback function.
84 Added support for HTTP Basic authentication in clients: the SRU/W
85 codec encodes the username/password elements of the PDU structure
86 appropriately, and these may be set using the "user" and "password"
87 options in ZOOM-C applications (the same options that are used for
88 Z39.50 authentication).
92 Fixed bug #1208: SSL appears to be broken in ZOOM.
94 Fixed bug #1206: Libxml2 include path weirdness.
96 Added oid_name_to_dotstring.
98 Allow elementSetName to be specified for ZOOM C record update.
100 Allow waitAction to be specified for ZOOM C based for Extended Services.
102 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
103 syntax OID. Bug introduced in YAZ 3 series.
105 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
109 Fixed bug #1157: yaz-client does not read .yazclientrc from current
110 directory. yaz-client now reads commands from file given by option -f
111 if specified; then tries to read .yazclientrc in current directory.
112 Failing that, it reads .yazclientrc from user's home directory.
114 Added support for correlationInfo Note and ID for Record Update via
117 Added yaz-client command querycharset which specifies character set for
118 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
119 (termListAndStartPoint).
121 Charset ISO5428:1984 is an alias for ISO5428-1984.
123 Implemented a way to perform scan in a result set using Z39.50. This
124 is achieved by attaching the result set name in the characterInfo
125 (type InternationalString) of OtherInformation in the Scan Request PDU.
126 The result set is identified in the otherinformation by the new OID:
127 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
128 This allows for scan in result set and faceted search . Zebra did some
129 of this in the APT term using attribute type 8 and value being result
130 set. Using the OtherInformation approach for this is cleaner and easier
131 to work with in proxies and the like. This facility can be used in
132 yaz-client using new command setscan which takes a result set as first
133 argument, start position (APT) as second.
135 Changed decoding of SRU XML packed records to deal with servers that
136 have recordData with XML data with multiple root nodes. Also make
137 comparison for recordPacking case insensitive. Again, one server
138 returns "XML" where others return "xml".
140 For SRU responses allow Content-Type application/xml as well as text/xml.
144 Fixed bug in character set conversion of BER strings. Bug introduced
149 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
151 For OID class, use oid_class consistently.
153 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
156 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
157 character set for bibliographic information interchange". By Giannis Kosmas.
159 Added documentation on new OID API.
163 Changes to generic frontend server interface: added new member
164 'query_charset' for bend_initrequest structure. A backend init handler
165 should set this member to its native character set for query terms.
166 When defined, the frontend server logic will announce this character set
167 to a client if the negotiationModel bit is set by the client. All server
168 implementors are encouraged to specify this. If a backend server does not
169 specify this a warning is issued using yaz_log(YLOG_WARN,..).
171 Added CCL utility to remove terms (stop words) from resulting RPN
172 tree. This is handled by functions with prefix ccl_stop_words_ .
174 New ZOOM C option, "rpnCharset", which allows client-side conversion of
175 terms in RPN queries.
177 Clean-up the CCL API. Moved some internal structures from ccl.h to
178 private header cclp.h. Changed ccl_parser_create so that a Bibset must
179 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
180 This is replaced by ccl_parser_find_str which takes a string instead.
182 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
183 libyaz.la is the core of YAZ except the generic frontend server and
184 does not depend on POSIX threads anymore. libyaz_server.la is the
185 generic frontend server facilities and uses POSIX thread functionality
186 if available. The libyaz.la no longer depends on POSIX threads because
187 the number of global structures is limited. NMEM no longer re-uses blocks
188 between threads ; it simply free's memory immediately but allocates in
189 "large" chunks as usual. We don't expect any performance penalties
190 because of this. The yaz_log system is still using a global log_level so
191 caution must be taken when modifying it with yaz_log_init_.. +
192 yaz_log_mask_str. This, however, should not cause any trouble because
193 these functions are called during initialization of application code
194 anyway. `yaz-config --libs server` returns libs for server applications;
195 `yaz-config --libs` returns libs for non-server applications.
197 New OID database - with public definitions in oid_db.h. Removed old OID
198 database including the head oid.h and definitions such as enum oid_value
199 and struct oident. The new OID database uses the same string names as
200 before but the 'protocol' is gone. There are now only two representations
201 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
202 converts from string to OID; functions with prefix yaz_oid_to_string
203 converts the other way.
205 Change to emit_term() in CQL-to-PQF query translation: when a term has
206 the /regexp relation modifier, do not process it for leading and
207 trailing "^" and "*", which have quite different meanings in regular
210 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
211 write handlers no longer carries a 'last' parameter. This will make
212 yaz_iconv flush "less" characters. A flush is performed by call to
213 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
215 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
216 removed, because function yaz_query_to_wrbuf does the same.
218 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
219 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
221 Deprecated MARC utility functions removed.
223 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
226 Branch split: YAZ_2_1_55_branch
228 --- 2.1.54 2007/03/16
230 Fix to ZOOM-C so that transparent reconnection is properly handled on
231 connections that are in asynchronous mode.
233 Fixed compilation on OpenBSD 4.0.
235 Large strings in GRS-1 records are now properly displayed in yaz-client.
237 Added character conversion support for "advancegreek"; based on patch from
240 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
241 sequence is met. Before the error was not set so it would be unknown.
243 Adjust yaz-marcdump MARC reader so that it skips until record separator
246 --- 2.1.52 2007/03/07
248 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
249 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
250 fd_set structure used as a bitmask for the FDs to be selected on.
252 Using ACX_PTHREAD macro to check for POSIX threads.
254 Fixed have-vsnprintf check.
256 --- 2.1.50 2007/02/23
258 Fixes for configure on BSD. Bug #900.
260 Added snprintf/vsnprintf wrappers for systems that don't have
261 limits (heavens forbid).
263 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
264 created before all previous tasks were completed and removed from the
265 task queue, the new task could be removed by a mistake.
267 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
269 Implemented pass-through CQL-to-PQF conversions. Bug #861.
271 Fixed bug #832: Problem with MARC/charset in yaz-client.
273 Fixed bug #668: save command line history for yaz-client.
275 Fixed bug #830: pkg-config support.
277 --- 2.1.48 2007/01/23
279 Extended ZOOM result set options with two options that may be read by
280 a client: resultSetStatus and presentStatus with values as specified for
282 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
284 Fixed bug #827: Using SSL fails on Debian etch.
286 Fixed bug #826: Weird looking chars for set of MARC records.
288 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
289 that is treated as an ItemOrder with itemRequest being an XML document
290 external. The value of "doc" is the content.
292 Extended the GFS search facility. New member of bend_search_rr
293 'estimated_hit_count' signals that hits is known to be an estmate
294 (higher or lower than real hit count). New member 'partial_resultset'
295 signals that the search was partial (hit count is lower or equal than
296 real hit count). For Z39.50, the information is stored in resultSetStatus
297 member of SearchResponse APDU. For SRU, the information is signalled
298 via SRU diagnostic 59: "Result set created with valid partial results
301 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
303 --- 2.1.46 2007/01/13
305 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
307 Added ZOOM_connection_peek_event.
309 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
310 the following new functions:
311 ZOOM_event_nonblock, ZOOM_connection_process,
312 ZOOM_connection_get_{socket,mask,timeout},
313 ZOOM_connection_fire_event_{timeout,socket}.
314 The existing blocking event handler, ZOOM_event, is a wrapper for the
315 + blocking ZOOM_event_sys_{poll,select}.
317 Implemented function ccl_xml_config which parses XML version of CCL
318 configuration (bug #798).
320 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
322 Added timings utility (yaz/timing.h)
324 --- 2.1.44 2007/01/03
326 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
329 Fixed bug #779: Rotation of apdu.log fails.
331 Fixed for character set conversions:
332 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
333 Honor G1 set in MARC-8 decoding.
335 --- 2.1.42 2006/12/17
337 Fixed bug #775: char conversion does not handle Alternative UTF-8
340 Implemented function yaz_marc_read_line which parses MARC line format
341 records. There is a wealth of formats out there. So far, this function
342 reads line records produced by yaz_marc_write_line.
344 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
345 more generic and easier to remember(!) options: -i format and -o format
346 which specifies input format and output format respectively - where
347 format is one of "marc", "marcxml", "line", "marcxchange".
349 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
350 does not print anything except warnings for records.
352 For yaz-marcdump, added support for MARC split into files (-s) with a given
355 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
356 spec, at http://www.loc.gov/standards/sru/record-update/
357 This has changed the binary layout of the following structs:
358 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
359 bend_update_rr . Patch by Ko van der Sloot.
361 Added GFS utility function bend_assoc_is_alive which returns 1 if
362 association is still alive (client is connected); 0 otherwise (client
363 closed connection). This allows busy servers to stop working for
366 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
367 been a separate piece of software. This version of ziffy has been modified
368 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
370 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
372 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
373 Client code may now interrogate options such as "init_opt_sort" to
374 find out whether the server claims to support various options.
376 --- 2.1.40 2006/11/27
378 Added utilities yaz_{set,get}_esn to set/get element set name from
381 Removed the build of libyazthread.la. The libyaz.so is the threaded version
382 of YAZ and has been so since YAZ 2.1.10.
384 Implemented ZOOM_record_error which returns error information for
385 record (surrogate diagnostic).
387 --- 2.1.38 2006/10/31
389 Updates for SRU Update by Ko van der Sloot:
390 1. Changed name from "operation" to "action"
391 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
392 versions in the code, marked as 'backward compatible'.
393 3. Added diagnostics for SRU Update.
395 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
397 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
399 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
401 For GFS, fixed problem with SRU diagnostic 'First record position out of
402 range' being issued for 0 hits.
404 zoomtst10 part of Windows Build.
406 --- 2.1.36 2006/10/13
408 Implemented yaz_filepath_comp which splits a path into file path
409 components (required by Zebra 2.0.3+).
411 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
412 BSD inspired license until now so this should not have any real impact on
413 anybody. See http://www.opensource.org/licenses/bsd-license.php
415 Fixed bug #687: Missing log lines.
417 Fixed bug #678: CQL to PQF translation does not preserve double-quote
420 Fixed bug #689: SRU diagnostics to be added.
422 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
423 whether a connection is idle (no more work do do).
425 --- 2.1.34 2006/10/04
427 Change type of optval from long to int for invocation of setsockopt with
428 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
430 Added support for specifying the max log file size for the Generic
431 Frontend Server. The size is given with option -r.
433 --- 2.1.32 2006/09/21
435 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
437 --- 2.1.30 2006/09/17
439 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
442 Fixed bug in Generic Frontend Server that could cause a server to stop
443 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
445 For the generic frontend server, the maximum record size is used as maximum
446 size of incoming packages (SRU + Z39.50). The value until was previously
447 only used in Z39.50 Init negotiation and, later, in a session controlled
448 sizes of records returned. This is controlled using -k option. It can be
449 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
451 --- 2.1.28 2006/09/04
453 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
456 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
458 New option for yaz-marcdump -lpos=value which allows setting a portion
459 of MARC header to a certain value.
461 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
463 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
464 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
466 --- 2.1.26 2006/08/15
468 Fixed problem with SRU mode type (soap, get, post) for yaz-client
471 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
473 --- 2.1.24 2006/08/08
475 Fixed MARC ISO2709 encoding routines to deal with character set
478 Minor changes to GFS logging. Database included in search request log
481 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
482 cached/multiple records.
484 Shared libraries are built by default on Unix+configure.
486 Changed cql2pqf transformation to use a different evaluation order. The
487 new order is: always, relation, structure, position, truncation, index
488 and relationModifier. Old order was: always, relation, relationModifier,
489 structure, index, position, truncation. Note that the the latter ones
490 override former ones for identical attributes.. The new scheme means that
491 it is possible to override any existing attribute with a relationModifier.
492 And also that it is possible to override everything for the index rule
493 (except the ones listed in relationModifier). No order is perfect but this
494 one, we believe, covers more real cases.. The "always" should have been
495 called "default", since the attributes there can be overridden with all
498 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
499 compilation phase, but also for yaz-config --cflags output. This allows
500 us to have public headers with Libxml2 stuff in them . It should also,
501 eventually, make Libxml2 checks redundant in packages using YAZ, such
504 --- 2.1.22 2006/06/15
506 Changed SRU update structure bend_update_rr so that SRU diagnostics are
507 stored in uri, message and details.. Previously diagnostics were stored
508 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
509 compatibility.. but he's probably the only one affected, so.
511 Added support for CCL, compiled on the client side, in ZOOM-C. This
512 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
513 input; the resulting query objects can be used for for searching with
514 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
516 YAZ' configure searches for OpenSSL by default.
518 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
519 SL_CTX_use_certificate_file. See
520 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
521 for more info. Thanks to Ko van der Sloot.
523 --- 2.1.20 2006/06/02
525 Bug #600: SRU GET, POST support for yaz-client. Introduced
526 command 'sru' which selects method SOAP/GET/POST.
528 Allow missingValueAction to be specified for the sortspec string -
529 function yaz_sort_spec. By default, the missing value action is null.
530 Use ! to specify "abort". Use = followed by stringvalue to specify default
533 Ensured that Present-handler (if defined) is called in GFS before any call to
534 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
535 searchRetrieve requests.
537 Documentation for YAZ is now based on the Docbook XML/XSLT using
538 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
539 is no longer depending on jade/openjade or docbook-to-man scripts.
540 PDF is no longer part of the distribution - but can optionally be
541 made using DSSSL/jadetex or FOP.
543 Added retrieval handling support in Generic Frontend Server to support
544 conversion between MARC/XML as well as XSLTtransforms. See
545 etc/yazgfs.xml for an example.
547 Added Authentication support to Generic Frontend Server in SRU
548 mode. Authentication using HTTP Basic is supported, as is the use
549 of 'x-username' and 'x-password' parameters in the request itself.
551 Added support for a new character set MARC8s identical to MARC8 except
552 that it converts combined characters to single Unicode characters in the
553 Latin-1 range (when possible).
555 --- 2.1.18 2006/04/24
557 ASN.1 compiler 0.4: generates brief Doxygen file header for
558 generated .h/.c files.
560 Utility yaz_iconv now supports conversion to MARC-8.
562 New facilities for the MARC module. The reading - and writing of
563 content are separate methods for the yaz_marc_t handle. The following
564 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
565 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
566 format). Write functions have prefix yaz_marc_write_.. The existing
567 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
568 available. Removed support for OAI-MARC and simplexml (not the
569 simplexml from PHP5).
571 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
572 to be returned for this connection.
574 --- 2.1.16 2006/03/31
576 Allow multiple languages and charsets to be specified with
577 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
578 negcharset iso-8859-1,utf-8
580 Translation of proximity nodes from CQL into PQF now works.
582 Moved to automake 1.8, 1.9.
584 Added function yaz_log_set_handler which allows a log handler to be
585 installed. This handler will be called for all log messages. Output
586 to file is also produced; but that can be disabled by passing NULL
587 fname to yaz_log_init_file.
589 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
591 For SRW (including GFS), accept application/soap+xml as content-type
594 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
595 produces NO stylesheet reference even if a default stylesheet is specified
598 --- 2.1.14 2006/03/14
600 Updated Windows package to include yazd.dll + yazd.lib for the
601 Development component.
603 If the environment variable YAZ_LOG is set, then it is used as a
604 string indicating the default level of logging to use if not
605 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
606 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
607 used as before. So, for example, to omit warnings from YAZ logging,
610 cql_transform() now map structure and other attributes before indexes,
611 so that index-specific structures and other attributes can override
612 defaults. So now a combination of mapping specifications such as:
614 index.dc.date = 1=date-modified 4=5
615 does the right thing.
617 cql_transform() now also respects the "always" mapping specification,
618 which establishes an initial set of attributes to be used for all
619 terms except where overridden by more specific attributes associated
620 with the index, relation or modifier.
622 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
623 which mode to use; one of "post", "get" or "soap" (SRW, default).
625 Fixes for yaz_iconv routines: changed trie-based character set conversions
626 to use only non-negative values for bit fields due to Sun's C compiler not
627 supporting negative values.
629 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
630 sequences where not read correctly. Fix by Rustam Usmanov.
632 Updated win/makefile to use options, settings which makes things
633 compile with VS C 2005.
635 --- 2.1.12 2006/02/01
637 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
639 In ZOOM socket code, use select instead of poll on MacOSX.
641 ZOOM-C now support client-side compilation of CQL into RPN that is
642 sent to the server, enabling CQL to be used against all Z39.50
643 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
644 ZOOM_query object, and submit it using ZOOM_connection_search().
645 The CQL-to-RPN translation uses a configuration file, the name of
646 which must be specified in the Connection's "cqlfile" option.
648 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
649 function, which takes as its start-term parameter a ZOOM_query object
650 (which may have had either CQL or RPN set into it).
653 --- 2.1.10 2005/11/29
655 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
656 GFS to support this as well. Backend handler, bend_srw_update, does the
657 update work. Code contributed by Ko van der Sloot.
659 Allow retrieval of Search Result-1 information in ZOOM by the use of
660 options that are attached to a result set. ZOOM documentation updated
663 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
664 UTF-8 conversion. Patch by Raj Patel.
666 Added option -m to GFS to control formatting of timestamps in log file.
668 Added 'exit' as synonym for 'quit' in yaz-client
670 Added support for specifying SRW resultSetId + resultSetIdleTime in a
671 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
672 for the new members. Patch by Ko van der Sloot.
674 Added support for SRU POST. It is supported for content-type
675 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
677 Do not build the separate Multi-threaded (MT) library libyazthread.la.
678 Instead make the library libyaz.la multi-threaded. Threading as a whole
679 can still be disabled by configure option --disable-threads. Previosly,
680 with older GLIBCs there were problems with MT libs under Apache. This
681 has now been fixed a long time ago.
683 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
686 CQL module modified to be case insensitive for relations/indexes/operations.
688 Fixed bug in CQL transform code: incorrect value relationModifieder
691 Added 'show all' command for yaz-client which retrieves all results
694 Added new yaz-client, xmles, which takes a (private) OID and
695 a document to be sent as an extended service request.
697 Describe new yaz-client commands wait_response and set_auto_wait.
699 Increase TCP/IP listener backlog from 3 (which I am guessing was
700 copied from the SunOS manual entry way back when) so SOMAXCONN, so
701 that the socket will queue as many incoming connections as it's able
702 to handle ongoing connections. In other words, it will never now
703 refuse a connection that it would be able to handle merely because
704 it's not got around to accepting() enough of the pending connections
705 yet. This is the behaviour anyway under Linux, where the listen()
706 argument is ignored; but not under BSD and on systems such as
707 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
708 YAZ-based servers should now be uniform across operating systems in
711 yaz-marcdump uses 64-bit file access on some systems. This is enabled
712 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
713 This allows yaz-marcdump to read large MARC batches (>2 GB).
715 Modified all YAZ source files - except the source which is auto-generated
716 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
719 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
720 corresponding to the existing *_setl() function. These allow option
721 values containing arbitrary valuues.
723 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
724 ZOOM_resultset_sort() in new applications. Its behaviour is identical
725 except that it returns an indicator of whether or not the sort
726 criterion was accepted (0 for OK, -1 for invalid).
730 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
731 MARC output rather than returning "new" buffer.
733 yaz-client warns about unknown init options.
735 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
739 Added support for SRW sort in Generic Frontend Server. Patch
740 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
741 sortKeys - or NULL if none is provided.
743 Fixed bug #307: It was impossible to specify indefinite/no timeout
744 for ZOOM_event. Special timeout value -1 now means indefinite timeout
747 Added support for multiple languages and charsets to be specified in
748 ZOOM. Each charset/language is separated by a blank. If negotiation is
749 in effect in init-response, Option
750 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
751 Code based on patch by Vasiliy Osadchuk.
753 Fixed bug #306: infinite recursion that occurred when calling
754 yaz_log_level_init as the first call (before other log level or
757 Fixed bug in scan handling in front end server: if preferred-Position-In-
758 Response was non-present, a NULL pointer referece was performed.
762 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
763 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
764 now defined for all those error codes. So instead of putting 109 in
765 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
766 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
768 Modified the yaz-marcdump utility to skip garbage bytes between MARC
771 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
773 Program yaz-client now exits and produces an error message if multiple
774 Z39.50 servers are specified on the command line (none or one allowed
777 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
782 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
784 Fixed bug #272: Preserve spacing for CCL terms.
788 Added support for virtual hosts and multiple backend servers for
789 the YAZ frontend server. The configution is XML based and
790 support specificition of CQL to RPN mappings and explain information.
791 See section "Virtual Hosts" in the YAZ manual.
793 Extended OPAC display utility. OPAC display utility renders
794 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
795 to supplement yaz_marc_decode_wrbuf.
797 Fixed a bug in MARC decoder that could caused it to crash for some
798 invalid MARC records. More diagnostics and warnings where added in
799 XML output (warnings, etc are stored in comments).
801 --- 2.0.34 2005/02/08
803 Fixes for UNIX domain sockets. Bug #261.
805 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
807 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
808 Added yaz_marc_subfield_str which defines subfield lead string which is
809 used in YAZ_MARC_LINE format. Default string is blank+$. Added
810 yaz_marc_endline_str which defines end of fields string used in
811 YAZ_MARC_LINE format. Default string is newline.
813 Experimental support for MarcXChange. This format can be produced
814 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
815 http://www.bs.dk/standards/MarcXchange.xsd
817 Added yaz-client commands scansize that sets maximum number of
818 entries to be returned by scan.
820 --- 2.0.32 2005/01/11
822 Added support for SRW scan in yaz-client and Generic Frontend Server.
824 * Added whereInList member to SRW Scan Term.
826 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
828 Fixed NMEM system to return aligned blocks on the smallest boundaries
829 that are suitably aligned for all possible types on the particular
830 architecture YAZ is being built for.
832 --- 2.0.30 2005/01/04
834 Fixed numerious warnings that was issued with newer versions of GCC.
836 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
837 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
840 Make YAZ Generic Frontend Server slightly faster.
842 Enhance (and reduce) logging for Generic Frontend Server.
844 Revert YAZ log system so that it flushes every write operation
845 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
847 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
848 instead of LOG_, due to name clash with syslog(3). LOG_ are still
849 present. New applications should define YAZ_USE_NEW_LOG=1 - this
850 will effectively disable old definitions.
852 --- 2.0.28 2004/11/09
854 Added yaz_log_time_format which specifies log format using
857 Added yaz_log_module_level which returns mask for a module. Value
858 is non-zero mask a if module is enabled; zero if disabled.
860 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
861 in include/yaz/cql.h.
863 Fixed bug #176: Dont throw diagnostics on empty SRU args.
865 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
867 Fixed bug #172: RPM builds does not enable SSL.
869 Doxyfile.in part of dist. Doxyfile generated by configure.
871 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
872 are given and the corresponding component does not exist.
874 Extend CCL documentation in YAZ reference. Describe r=r.
876 --- 2.0.26 2004/10/01
878 Fixed MARC->MARCXML conversion to properly deal with
879 fields, subfields, indicators having non-ASCII characters.
881 Fixed MARC->MARCXML conversion so that ASCII control characters
882 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
885 Added YAZ GFS support for conversion from Z39.50 surrogate
886 diagnostics to SRW surrogate diagnostics.
888 Bug fix: YAZ GFS did not return schema in explainResponse.
890 --- 2.0.25 2004/09/30
892 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
893 now converts recordSchema to elementSetName as well as schema URI.
895 Fixed bug in COMSTACK that prevented HTTP request packages from being
898 --- 2.0.24 2004/09/29
900 Added CCL facility r=r "range" which is similar to r=o "ordered" but
901 does not require white-space before and after the dash in a range, e.g.
902 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
905 Fixed a few AC_TRY_LINK configure tests that did not operate properly
906 due to new GCC removing "redundant" code.
908 Added yaz-client commands scanpos and scanstep that sets preferred
909 position and step-size for scan.
911 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
913 Added CCL utility ccl_qual_buf which parses one or more CCL
914 spec lines in a buffer.
916 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
917 of name and value - ignoring empty lines and comments.
919 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
921 Added odr_get_element_path which returns current element path for an
922 ODR handle. This utility is useful in error handling or user-defined
925 Added ODR_PRINT utility odr_set_stream which is is a more generic
926 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
927 to a write function and pointer to close function. The close function - if
928 non-NULL - will be called during odr_destroy.
930 Fixed bug in CCL parser where truncation char was not removed from
931 right side when truncation=both was in effect.
933 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
936 --- 2.0.23 2004/08/11
938 Fix buffer overrun in CQL parser when dealing with proximity (%).
940 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
941 to UTF-8/UCS conversion is now only based on codetables.xml.
943 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
945 --- 2.0.22 2004/08/06
947 Add support for more "commit changes" in ZOOM (uses Extended Services).
949 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
952 Yet another small fix for configure of SSL.
954 --- 2.0.21 2004/05/14
956 Fix SSL libs for configure when --with-openssl=DIR is given.
958 --- 2.0.20 2004/05/10
960 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
962 SSL comstack now uses yaz.pem certificate file on server side
963 by default. Certificate filename can be configured by calling
964 comstack function cs_set_ssl_certificate_file before cs_bind is used.
966 Fix bug regarding multiple calls to ZOOM_connection_connect.
968 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
970 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
971 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
973 ZOOM now allows inspection of X509 peer certificate for verification.
974 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
976 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
977 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
978 as "modular" but it simplifies things.
980 Added cs_get_peer_certificate to that returns peer X509 PEM.
982 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
983 NULL if SSL is unavailable.
985 Documentation about MARC decoding tools.
987 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
989 --- 2.0.19 2004/03/30
991 Rename CHANGELOG to NEWS to follow GNU style packing.
993 Fix bug with missing initialization of member in init_diagnostics.
994 This bug affects threaded version of GFS server.
996 --- 2.0.18 2004/03/20
998 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1001 Ensure zlib.dll is packed with Windows install.
1003 --- 2.0.17 2004/03/17
1005 Fix encoding of xsd:string to use text instead of CDATA.
1007 Fix endless loop in CQL parser with unbalanced ".
1009 Use a more compact way to store MARC-8 conversion tables.
1011 --- 2.0.16 2004/03/16 Debian only
1013 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1016 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1021 --- 2.0.15 2004/03/01
1023 Another fix for decoding of XML packed records.
1025 --- 2.0.14 2004/02/25
1027 Fixes for Chunked encoding. White space not ignored after length spec.
1029 Update NS and use default NS for SRW diagnostic elements.
1031 --- 2.0.13 2004/02/23
1033 Implement ZOOM_resultset_cache_reset which resets record cache.
1035 Implement ZOOM_resultset_sort which sorts a result set.
1037 Implement chunked HTTP transfer.
1039 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1041 --- 2.0.12 2004/02/16
1043 Added member 'schema' to bend_explain_rr structure so that backend
1044 can specify explain record identifier. Defaults to Zeerex 2.0.
1046 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1048 --- 2.0.11 2004/02/16
1050 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1053 Added init command for yaz-client which sends "extra" init request.
1055 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1056 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1058 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1060 Make ZOOM error code for "invalid query".
1062 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1064 --- 2.0.10 2004/02/05
1066 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1069 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1071 Added option -p <file> to make Generic Frontend Server to write PID file.
1073 Added option -D to put Generic Frontend Server in background on its own.
1075 Make ZOOM C recognize option "password". If unset, "pass" is used
1076 (for backwards compatibility).
1078 Fixed a bug in Generic Frontend Server that could make it crash if a
1079 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1082 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1083 Must be issued before open, in order to be in effect.
1085 --- 2.0.9-6 2004/01/12 Debian/Windows
1087 Make the SRU server more picky WRT unknown params, etc.
1089 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1091 New YAZ client command, options, that sets Z39.50 options.
1093 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1094 options from a string of tokens (one token for each option bit).
1096 Update SRW diagnostic code messages.
1098 --- 2.0.9-5 2004/01/07 Debian/Windows
1100 Handle user defined stylesheet for SRW/SRU.
1102 --- 2.0.9-4 2004/01/06 Debian/Windows
1104 Fix bug in decoding of Content-Length.
1106 --- 2.0.9-3 2004/01/06 Debian/Windows
1108 Fix a bug with decoding of XML packed records.
1110 --- 2.0.9-2 2004/01/05 Debian only
1112 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1114 Fix bug in SRW/SRU diagnostics decoding.
1116 --- 2.0.9 2004/01/05
1118 Fixed bug in Generic Frontend Server which could drop records exceeding
1119 preferred message size. Reported and fixed by Irina Dijour.
1121 Fixed calculation of package size for structured records in Generic
1122 Frontend Server. Reported and fixed by Irina Dijour.
1124 Fixed namespace for SRW/SRU diagnostics.
1126 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1128 --- 2.0.8 2003/12/22
1130 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1131 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1134 CQL changes to reflect recent changes to the specification:
1135 * Documentation talks about context sets instead of index sets.
1136 * Documentation talks about indexes instead of qualifiers.
1137 * The CQL-to-PQF transformer's configuration file now uses
1138 "index.set.name = <attributes>" instead of the old form
1139 "qualifier.set.name = <attributes>". (Both forms are still
1140 understood but the latter is deprecated.)
1141 * CQL terms with no explicit index specified are now interpreted as
1142 cql.serverChoice instead of srw.serverChoice (which of course
1143 behaves exactly the same.)
1145 --- 2.0.7 2003/12/16
1147 MARC conversion can now generate ISO2709 output in another
1148 character set. yaz-marcdump uses this facility if you invoke it
1151 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1152 functions from there can be used from C++.
1154 --- 2.0.6 2003/12/04
1156 Frontend server now transfers memory from decoded packages to stream
1159 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1160 references to show up.
1162 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1163 the ZOOM Abstract API. The older names for the same options are still
1164 also supported for the benefit of old applications.
1166 ZOOM-C supports "implementationId" and "implementationVersion" options
1167 to go along with "implementationName". These allow the user code to
1168 specify identification strings to be sent to servers.
1169 Add OID for the new ExtLite attribute set.
1171 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1172 as requested/supplid by Ere Maijala <ere@atp.fi>
1174 For generic frontend server, reverse the order of
1175 "toolkit-supplied / application-supplied" strings sent as implementationId,
1176 Name and Version. Also, remove the spaces around the slash. This brings
1177 the GFS in line with the behaviour of ZOOM-C on the client side.
1179 Add function ZOOM_scanset_display_term.
1181 yaz-client shows scan displayTerm if present.
1183 Utility yaz-iconv is now installed by default along with the man page
1186 Extend configure check for OpenSSL to use pkg-config where available (such
1189 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1190 server to specify uid/gid/mask for socket using the format
1191 unix:[user=uid,][group=gid,][umask=mask,]file=path
1192 If file= is omitted the existing format is assumed, e.g.
1194 in which case the mask is 0666 (rw for everybody).
1196 Major restructure of YAZ source. All source in libyaz is in src directory.
1197 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1198 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1200 Added man page for utility yaz-marcdump (used to be called marcdump).
1201 yaz-marcdump is installed by 'make install'.
1203 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1204 of incoming package failed.
1206 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1208 Change prototype of odr_perror: add const to message string.
1210 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1212 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1213 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1214 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1215 DNS lookup. There should not be any compatibility problems with this
1216 assuming that blocking=1 or 0 is used.
1218 Fix bad reference in UNIX comstack in function cs_addrstr.
1220 Fix for compilation on AIX.
1222 The generic front-end server (server/seshigh.c) now supports returning
1223 Init diagnostics to the client in User-information-field, in
1224 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1227 --- 2.0.4 2003/09/04
1229 Allow any CQL relation (not just all,any,exact,scr).
1231 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1232 that features the same UI.
1234 Implemented command update0 in YAZ client which is equivalent to
1235 update but uses old of Ext Update ASN.1.
1237 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1238 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1239 Previously no OID was used for this info.
1241 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1242 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1243 returns 'malformed search term' otherwise.
1245 SortResponse member resultCount now set to NULL in sort handler of
1248 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1251 Add three new utility functions for translating OIDs between various
1252 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1253 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1254 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1255 char *oid_to_dotstring(const int *oid, char *oidbuf);
1256 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1258 Reverted modifications for ES Update definition for z_IU0Update
1259 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1260 is back to YAZ 2.0.2.
1262 String value attributes for CCL parser.
1264 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1265 which their FirstSearch server returns in Init responses, sometimes
1266 carrying useful diagnostic information when Init fails. This has the
1267 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1268 "z39.50/oclcui.asn", where its definition is somewhat different from
1269 what OCLC document on their web-site, as required to interoperate with
1272 Support for anonymous authentication in yaz-client. Use the command
1275 * Fix the OID of the Index Data-local "admin" Extended Service from
1276 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1277 the 1000, which indicates a locally-defined OID, was a mistake.
1279 --- 2.0.3 2003/06/20
1281 Fix CCL directive @case handling so that it affects string match for
1282 both CCL keywords and qualifiers.
1284 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1285 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1286 Decoder has been updated with ASN.1 changes as listed in
1287 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1288 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1289 z_IUUpdate, remains unchanged.
1291 ZOOM_record_get may now return a record in a specific character set.
1292 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1293 "from" is the character set of record as returned by target. "to" is
1294 the character set to be returned. If omitted, "to" is UTF-8.
1296 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1298 New ODR utility, odr_getelement, which returns name of element for
1299 which encoding/decoding failed.
1301 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1302 in cases where a required element was omitted.
1304 Bug fix: some MARC8 sequences were not converted.
1306 New ZOOM option "step" which specifies number of records to be
1307 retrieved in one chunk. Used in conjunction with "start" and "count".
1309 SRW support for yaz-client. Use scheme http: to use it, e.g.
1312 yaz-client no longer does (un)intelligent character set conversions
1313 by default. Can be enabled with charset and marc_charset commands.
1315 xmalloc trace fix for 64-bit systems such as DEC alpha.
1317 Solaris 2.6 compile fix.
1319 New function, cql_strerror() translates SRW error codes, as returned
1320 by cql_transform_error(), into human-readable English strings. Used
1321 in yaz-client diagnostics when appropriate.
1323 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1324 converts it into a type-1 query which is sent to the server. This
1325 makes CQL available for use with all Z-servers, as opposed to the tiny
1326 minority that can handle CQL queries themselves.
1328 --- 2.0.2 2003/04/28
1330 New Debian package layout similar to the Redhat Package layout.
1332 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1333 and search result respectively.
1335 --- 2.0.1 2003/04/25
1337 Redhat package is now several packages: libyaz (runtime libraries),
1338 libyaz-devel (development and documentation, and yaz (utility programs).
1339 Package spec file by Morten Bøgeskov.
1341 New member 'schema' in struct bend_fetch_rr which the name of requested
1342 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1343 handler MAY set this to reflect the schema of the returned record.
1345 New member 'display_term' in struct scan_entry. GFS now sets member entries
1346 and allocates scan entries to be filled by user scan handler. In previous
1347 version, entries member was allocated by the scan handler. That still works,
1348 but the GFS will ignore member display_term - assuming it was NOT set by
1349 the handler. The fact that the GFS now allocates the entries both allows
1350 for new members and makes a scan handler easier to write.
1352 Fix CQL lex buffer overflow.
1354 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1355 SRU default recordPacking is string.
1357 SRU protocol support for frontend server.
1359 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1361 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1363 Added scan for the ZOOM shell (zoomsh).
1367 * String Identifers for Schemas (Amendment 5).
1368 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1369 Old definition for schema
1370 Odr_oid *schema; /* OPT */
1375 Z_InternationalString *uri;
1376 #define Z_Schema_oid 1
1377 #define Z_Schema_uri 2
1380 * resultCount parameter to Sort Response (Amendment 1).
1381 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1383 Support for SRW 1.0 over HTTP. This is an optional feature and
1384 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1387 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1388 on the same port. SRW SearchRetrieveRequests are mapped
1389 to bend_init,bend_search,bend_fetch,bend_close.
1391 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1393 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1394 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1396 ZOOM connections are SRW based if schem http is used for hostname
1397 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1398 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1400 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1401 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1402 distance=n, order=true/false, relation=le, prox unit=word. If
1403 n is omitted, distance 1 is used.
1405 Fixed problem with C compiler include path in wrong order.
1407 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1408 on Solaris. Patch from Ko van der Sloot.
1410 New MARC decode API. All new functions operate on a yaz_marc_t
1411 handle. The most important new functions are: yaz_marc_create,
1412 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1413 decode and destroy respectively. Decoder can produce formats
1414 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1415 include/yaz/marcdisp.h.
1417 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1418 to UTF-8, UCS-32, wchar_t or Latin-1.
1420 * Prototypes for yaz_iconv_-functions moved to separate header
1421 include/yaz/yaz-iconv.h.
1423 Make a few private functions 'static' in unix.c. This prevents
1424 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1426 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1427 are set when Init Response is received.
1429 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1430 but returns diagnostic set as well.
1432 New function yaz_strerror which is a portable wrapper for
1433 strerror/strerror_r/GetLastMessage.
1435 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1436 is returned for MARC. If type is "oai", then OAI MARC is returned.
1438 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1441 --- 1.9.2 2002/11/26
1443 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1445 Fix bad race conditions on SIGTERM and terminate gracefully in
1448 Move retrieval (data1) module to Zebra since nobody seems to be
1451 Add GRS-1 render for ZOOM using same format as yaz-client.
1453 --- 1.9.1 2002/10/05
1455 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1457 Fix broken ESpec handling in data1 module.
1459 SGML reader parses comments and makes them part of the data1 tree.
1461 Added several type casts so that YAZ compiles as C++ code.
1463 ZOOM didn't handle PDU encoding failures properly.
1465 Added more Bib-1 diagnostics (approved extensions).
1467 GNU configure: better check for iconv.
1469 More portable use of accept, getpeername. Check for socklen_t. Use
1470 int/size_t if socklen_t is not defined.
1474 PQF parser rejects bad queries - including those with extra
1475 characters in them. PQF parser used to silently ignore that.
1476 Cleaner API for PQF added, which allows you to get detailed
1477 error information for bad queries (see yaz/pquery.h).
1479 Fixed bug in ZOOM_record_get for type "database".
1481 Implemented mini iconv library supporting conversions between
1482 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1484 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1486 --- 1.8.9 2002/08/20
1488 Fixed ZOOM C record cache so that preferredRecordSyntax and
1489 elementSetName is used to check for already fetched records.
1491 --- 1.8.8 2002/08/02
1493 Added three members in bend_initrequest structure to facilitate
1494 character set negotiation.
1496 Fixed a bug in frontend server that could cause indefinite
1497 loops under rare conditions.
1499 Revised character set utilities (charneg.h) so that encoding
1500 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1502 For PQF, directive @term <type> sets term type for Scan/Search.
1503 Here <type> is general, string, numeric, null. The term type
1504 is inherited - just like @attr.
1506 New call odr_set_charset that sets character set conversion for
1507 international-strings on a ODR stream. Prototype is:
1508 int odr_set_charset(ODR o, const char *to, const char *from);
1509 The InternationalString is still represented as C string in YAZ
1510 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1511 won't). On the protocol level, you can use any encoding.
1513 Support for UNIX sockets in ZOOM.
1515 Solaris recv sometimes returns errno == ENOENT. It is treated as
1516 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1518 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1519 both client and server. Code by Morten Bøgeskov.
1521 --- 1.8.7 2002/05/22
1523 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1524 that they can be used directly from Visual Basic. You must recompile
1525 your windows APP if you're using ZOOM.
1527 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1528 Commands "lang" and "charset" sets language and character set respectively.
1529 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1530 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1532 Attributes from multiple CCL fields may be OR'ed rather than merged
1533 using directive "@field or". Fields are still merged by default -
1534 equivalent to "@field merge".
1536 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1539 Fixed bug in zget for parameter ExtendedServicesResponse.
1543 --- 1.8.6 2002/03/25
1545 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1547 Client displays USR.1:SearchResult-1 (hits per term).
1549 Additional Search Info for search in Generic Frontend Server.
1551 Fixed CCL parsing of "field=s".
1553 WIN32 installer - using the excellent NSIS software from nullsoft.
1555 Fixed CCL parsing of "field = - <number>".
1557 Added function yaz_marc_decode that decodes MARC for line mode
1558 display or XML (similar to that used by JZKit).
1560 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1561 Z39.50. But ISO/ILL was, however.
1563 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1564 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1566 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1567 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1569 --- 1.8.5 2002/02/03
1571 New YAZ client features: Command completion and new commands:
1572 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1573 Code provided by Jacob Poulsen.
1575 New call oid_trav, that visits all registered OIDs via callback.
1577 Function ZOOM_record_get now returns const char pointer rather than
1578 void pointer. It saves a lot of type casts.
1580 For YAZ client, command "auth" now allows you to set authentication
1581 in IdPass style. It is enabled when three tokens are given - order
1582 is user, group and password.
1584 Fix memory leaks in MARC record handling for ZOOM.
1586 New option for YAZ client, -k <kilobytes> that sets
1587 maximum record size. Similar to -k option for generic frontend
1588 server and yaz-ztest.
1590 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1592 Prefix query parser reports "fail" when bad attribute set is given.
1594 Fix in MARC decoder. Proximity logging. Fix for attribute set
1595 in scan handler for server. Patches by Shigeru Ishida.
1597 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1600 Configure option --with-openssl=<dir> now works when a directory is
1601 specified. Patch provided by Morten Bøgeskov.
1603 New option for YAZ client, -u <auth>, that sets authentication.
1605 ZOOM fix: error information was sometimes "missing", since error
1606 was cleared/reset too when it shouldn't.
1608 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1610 --- 1.8.4 2002/01/04
1612 Scan for ZOOM API. New object ZOOM_scanset. New functions
1613 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1614 ZOOM_scanset_destroy.
1616 New ZOOM function, ZOOM_connection_last_event, that returns type
1617 of last event (such as "receive data", "send data", "apdu received",
1620 New ZOOM option, schema, that specifies schema for retrieval.
1622 New CCL feature. Qualifiers can be aliases for one or more
1623 other qualifiers (if more than one is given, OR is used).
1625 ZOOM uses named result sets if target supports it.
1627 Two new YAZ client commands: . (dot, which sources a script of YAZ
1628 client commands), and ! (to execute shell command.). Implemented
1631 Working on Debian packages.
1633 --- 1.8.3 2001/11/19
1635 YAZ client enables named result sets only if target supports it.
1637 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1639 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1640 with key="host" to get same result.
1642 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1643 Function Z3950_resultset_record(s) returns references to records
1644 "owned" by resultset. To become owner use Z3950_record_clone.
1646 Function z_ext_record handles Extended Services. Thanks to
1649 --- 1.8.2 2001/11/12
1651 CCL Parser fix: ignore token comma when dealing with and-lists.
1653 Documentation updates for COMSTACK.
1655 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1656 Changed prototype Z3950_records. For some functions, int parameters
1657 were changed to size_t.
1659 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1662 New MARC decode/display function, marc_display_exl, which properly rejects
1663 non-ISO2709 records. YAZ client uses it.
1665 --- 1.8.1 2001/10/29
1667 Fix bug: local attribute set wasn't set correctly in PQF strings.
1671 * Old Z39.50 codecs no longer supported.
1673 Added ZOOM C binding. See http://zoom.z3950.org/
1675 Renamed states for COMSTACKs to avoid confusion with events.
1677 Implemented cs_look and proper cs_rcvconnect.
1679 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1681 Configure detects POSIX threads on OpenBSD.
1683 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1684 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1686 When error is returned from present handler, non-surrogate diagnostic
1687 is returned in present response (and fetch handler is no longer called).
1689 * Minor adjustments to pquery parser (PQF). Token characters may be
1690 escaped by using backslash (C-style).
1692 PQF parser allows string attribute values to be specified. For @attr,
1693 non-numeric characters after the equal-sign are treated as strings
1694 (e.g. @attr 9=title).
1696 CCL trunction character may be defined (@truncation in file)
1698 * function zget_ExtendedServicesRequest sets waitAction to
1699 waitIfPossible (was wait).
1701 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1704 CCL operator names may be set in field definition files (CCL_bibset).
1705 See ccl/bib1 for an example.
1707 Fixes in ASN.1 compiler for C++ compatibility.
1709 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1710 and "op_or" to avoid conflict with C++.
1712 Fixed problem with GNU readline detection on Redhat 7.0.
1714 Added step-size for Scan backend handler.
1716 Fixed bug that made the frontend server crash when no attribute
1717 set was specified for scan.
1719 Front-end server automatically switches to original working directory
1720 when installed as an NT service. Previously -w had to be specified to
1723 Added extended attributes for retrieval module (data1), so that data1
1724 records carry d1_readXML/SGML attributes. d1_read also supports
1725 null-data rules ( <tag/>)
1727 On UNIX when POSIX threads are available, a separate library libyazthread
1728 is created. Programmers should link with that library and the yaz library
1729 when using threads. The reason for the split was that some applications
1730 on Linux, such as Apache, doesn't work well when using shared objects that
1733 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1734 (or any frontend server) in SSL mode by specifying ssl: followed by
1735 address. Only tested on UNIX.
1737 Added feature for CCL module. Virtual structure s=al or s=ol generates
1738 and-list and or-list respectively instead of phrase search.
1742 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1743 log_mask_str. This was done to avoid name conflicts with other libraries
1744 (such as other PHP extensions).
1746 Added raw OID member for preferred record syntax (request_format_raw)
1747 and returned record syntax (output_format_raw) for backend fetch method.
1749 Config file yaz-config now accepts options so that it returns specific
1750 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1752 Shared library support for UNIX using GNU libtool.
1754 * Modified backend interface. Request/Response struct's replaced by
1755 one read/write C struct. For example bend_fetchrequest and
1756 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1757 Every handler - even search has to be registered in bend_init
1758 handler. This means that the YAZ library no longer refers to
1759 external functions and it makes it possible to make the whole
1760 thing a single DLL/SO.
1762 Added Segment handler for backend server.
1764 Added Zmbol/Zebra administrative functions to YAZ client.
1766 Threaded frontend server on UNIX (when POSIX Threads are available).
1767 Starting the server with option -T enables multi-threading.
1771 Added configure option --enable-comp/disable-comp to control use
1772 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1773 located in sub directory asn.
1775 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1776 in ${exec_prefix}/bin along with the other programs yaz-client and
1779 GNU automake used to maintain makefiles.
1781 Added several OID's.
1783 Changed retrieval module so that we can load records with no abstract
1784 syntax defined. Tagpaths in these records are fully composed of string
1787 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1791 On UNIX, the generated makefile now supports a proper 'make install'.
1792 The prefix can be set via GNU configure to set the install location
1793 (default is /usr/local).
1795 * YAZ programs client and ztest were renamed to yaz-client and
1796 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1797 locations, such as /usr/bin,/usr/local/bin,etc.
1799 * YAZ Header files were moved from include to include/yaz. YAZ Header
1800 files are referred to as include <yaz/log.h> rather than <log.h>.
1801 The YAZ include path (-I ..) is therefore the same as before. Programmers
1802 should update their #include statements or use -Ipath/include/yaz
1803 instead. The main motivation for doing this change is that YAZ header files
1804 can be installed in "standard" locations /usr/include,/usr/local/include
1805 without introducing conflicts, since ALL YAZ header files are stored
1806 in subdirectory yaz (under /usr/include for example).
1808 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1809 rather than project/workspace files. We switched because project files
1810 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1813 Changed name of logging function, logf, to yaz_log, to prevent name
1814 clash with some math-log functions. The YAZ header log.h defines logf
1815 to yaz_log (#define) so there should be no incompatibilities by this
1818 Added bend_start/bend_stop handlers for server. These handler are
1819 called on start/stop of server. For windows they are called whenever
1820 a service is started/stopped.
1822 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1823 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1824 in util/yc.tcl. The auto-generated C code structures are, in a few
1825 cases, incompatible with the old decoders. There are differences in the
1826 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1827 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1828 The preprocessor variable ASN_COMPILED is defined when the compiled
1829 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1830 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1831 wish to use the old encoders/decoders you can specify --disable-yc
1834 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1835 version so that it supports both new - and old version of DB Update
1837 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1838 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1839 change. The name parameter can be set to 0 in which no name is specified
1840 for the construction. The macros odr_implicit and odr_explicit sets name
1841 parameter to zero for the construction involved. New macros
1842 odr_implicit_tag and odr_explicit_tag are similar to the others,
1843 except that a name parameter is added. For programmers' that don't use
1844 ODR they probably only need to change the call to z_APDU and z_External.
1846 Added access control facility by interfacing the TCP wrapper library.
1847 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1848 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1849 name of the daemon and enables the access control as specified in
1850 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1852 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1853 den Dool <H.M.vdnDool@kub.nl>.
1855 Added reference ID parameter to most functions in server API - refer
1856 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1858 Changed name of ccl library to libccl.a (was ccl.a).
1860 Fixed bug in decoder for Explain (Category TargetInfo).
1862 Added support for GNU readline in client. Thanks to Jacob Poulsen
1863 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1865 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1866 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1867 IMPLEMENTATION! This change was made to the development version before
1868 the ZIG decided to retract the amendment. If any users MUST be
1869 compatible with the original Update definition, PLEASE CONTACT US, and
1870 we will include a separate definition corresponding to the old Update
1871 ES. Note that because of the change to the ASN.1 of the
1872 TaskPackageRecordStructure we cannot define a single structure that
1873 will support both versions.
1875 * Added const modifier to buffer parameter for some ODR/BER encoding
1876 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1877 completeWAIS, odr_dumpBER.
1879 Fixed bug in client.c which caused a crash when a scanResponse didn't
1880 contain positionOfTerm.
1882 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1883 * will cause an error in a client if a non-YAZ target sends both a
1884 * list of Scan entries and non-surrogate diagnostics.
1886 Retrieval module enhancements. Tag sets may be typed in the reference
1887 to it. From the .abs-file the "tagset" directive takes a third optional
1888 integer type for the tag set referenced. From a .tag-file the "include"
1889 directive takes a third optional type as well. The old "type" directive
1890 in the tag set itself is still recognized but acts as the default type
1893 Backend interface change. Individual Scan terms returned from bend_scan
1894 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1895 in include/backend.h.
1897 Retrieval module enhancements. Multiple tag sets and attribute sets may
1898 be specified in abstract syntax specs. Revised the error/warning for
1899 logging messages reported by the retrieval module when reading the
1902 Object Identifier system (oid_..) changed. The API is backwards
1903 compatible but the oid-routines now allocates new OID's when needed.
1904 Raw OID's may be specified in oid_getvalbyname.
1906 YAZ now uses GNU configure to generate Makefile(s).
1908 * Minor changes in some of the member names of DeleteResultSetRequest and
1909 DeleteResultSetResponse. See include/proto.h.
1911 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1912 and added member 'languages' in TargetInfo (which was missing).
1914 Changed the way attribute sets are handled in the retrieval
1915 module. These are now cached, just like the abstract syntaxes
1918 Changed YAZ so that it links with compiled ASN.1.
1920 Added Explain-schema definitions and mapping routines. The following
1921 Explain categories have been implemented: AttributeDetails,
1922 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1924 Fixed minor bug in Windows version of Server Library.
1926 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1928 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1930 Added EXTERNAL: UNIverse Resource Report (non-standard).
1932 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1933 ENUMERATED and SET OF.
1935 * Added 'const' to some of the char pointer arguments for the
1936 functions, data1_read_node, data1_getelementbytagname,
1937 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1940 Fixed bug in data1_insert_taggeddata - the last_child member of
1941 parent wasn't initialised.
1943 * Changed data1_read_record and data1_read_node so that the supplied
1944 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1945 doesn't refer to any parts of the "SGML"-buffer.
1947 Fixed bug in server library (Windows version of statserv_remove).
1949 * Changed code so that it compiles as C++. The type definition
1950 of Odr_fun which is a member of Odr_arm was changed. The result is,
1951 that an explicit typecast is needed for the fun pointer when
1952 using Odr_arm - as in:
1953 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1955 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1957 Implemented the new structured date and time definition as approved
1958 by the ZIG. Added schemaId element to the specificTag in Espec-1
1959 (also approved at the last ZIG). Thanks to RVDM.
1961 Added some Object identifiers (RVDM).
1963 Changed the Update Extended Service (RVDM).
1965 Added command "refid" to client which specifies referenceId for
1966 the following requests.
1968 Implemented extended service handling for server. See ztest.c
1969 for an example as well as backend.h. New handlers are registerd
1970 in the Init handler.
1972 * Changed interface for sort in server.
1974 Added new members to statserv_options_block. It allows a server
1975 to read options from another source than just the command line. Thanks
1976 to Charles Woodfield.
1978 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1979 renamed to zboolean. Some C++ compilers complained about the name.
1981 Minor changes to gils.abs. Added index 's' (sort) on title
1982 and date/time-last-modified.
1984 --- 1.4pl2 1998/1/30
1986 Fixed bug in server library regarding inetd mode (-i). This bug
1987 was introduced by release 1.4.
1989 --- 1.4pl1 1998/1/29
1991 Added sort facility in client and backend server interface.
1993 Fixed problem with dependencies in Makefile(s).
1995 Fixed bugs for encoders/decoders of extended services and
1998 Implemented sub-tree feature for schemas. Sub-trees are
1999 referenced in *.abs-files. See explain.abs for an example
2000 of the use of this feature.
2002 Modified bib1.att; local attributes for ANY didn't include
2003 ANY itself (only affects use of the retrieval module).
2005 Fixed bug in plain SGML reader in function data1_read_node:
2006 tags with prefix "var" was incorrectly interpreted as variants.
2008 Added feature "sub-schemas" to enable references to - and definitions
2009 of - group of elements.
2011 * Removed member parent from type data1_element (in data1.h).
2013 Implemented function odr_nullval() that returns the value of
2016 * Removed member num_children from data1_node (in data1.h).
2018 Made NT service interface part of the server library. The
2019 function statserv_main uses the NT service when required and
2020 calls the statserv_start / statserv_close routines.
2022 Routine zget_SearchRequest and zget_PresentRequest fills
2023 resultSetName/Id member with "default" instead of "Default".
2025 Fixed memory leak in server. Request queue member wasn't freed.
2027 Fixed nmem_exit so that memory is freed.
2031 Revised the CCL parser utility to be thread safe.
2033 Added function, oid_ent_to_oid, to replace the function
2034 oid_getoidbyent, which is not thread safe.
2036 * Added nmem_init and nmem_exit to initialize and release
2037 NMEM resources. Function nmem_init should be called once in the
2038 initial thread before NMEM/ODR is used. statserv.c and client.c
2039 have been changed accordingly. The change was necessary to make
2040 NMEM thread safe. The NMEM memory pool is shared amongst threads
2041 in a process. Unix-based applications will still work fine without
2044 Added NT Services interface for the the Z39.50 (statserv) Server.
2045 Refer to the ztest.c source on the usage.
2047 Windows 95/NT port using MSVC5.0. Project files are included in the
2050 * Defined new 'global' handle for the retrieval (data1) system. The
2051 new handled, data1_handle, describes the state of the data1 system.
2052 This handle is passed as first argument to virtually all
2053 data1 related routines. The functions data1_create and data1_destroy
2054 creates and destroys a data1 handle respectively.
2056 Added ODR encode stream member to all backend request structures
2057 init, search, scan etc. This stream should be used to allocate all
2058 memory used for the response when thread safe operation is needed.
2060 Changed the comstack utility, cs_addstr, to be thread safe. The
2061 returned hostname string returned by the function is now part the
2064 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2065 function. The cs_straddr takes a COMSTACK handle as argument, so this
2066 function must be used after cs_create and before bind/connect.
2067 This function is thread safe.
2069 Moved test server to 'ztest' directory - generic server code still
2070 in 'server' directory.
2072 Made prefix query (pquery.c) utility thread safe.
2074 Added new function modifier YAZ_EXPORT to 'export' public DLL
2075 functions when using windows (see include/yconfig.h).
2077 Added definitions to the OID database (util/oid.c) (RVDM).
2079 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2081 Added call to ccl_rpn_delete in client program.
2083 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2084 release of RPN structure.
2086 Added support for C++, headers uses extern "C" for public definitions.
2087 With input from RVDM.
2089 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2090 Thanks to Ronald van der Meer (RVDM).
2092 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2094 Added support for private extensions to the OID database
2095 (oid_setprivateoids()). Thanks to RVDM.
2097 Added optional, physical ANY (key replication)
2099 Fixed null-reference problem in GRS-1 output filter.
2101 Proximity operator added to Prefix Query Format (PQF).
2103 In test client command "base" accepts multiple databases.
2105 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2109 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2111 Smallish bug-fixes in the new encoders/decoders (explain).
2113 Bug fixed in DeleteRequest.
2115 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2117 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2119 Added SOIF syntax (using private OID for now) to retrieval module and client.
2121 Added Update extended service.
2123 Added SearchResult-1 additional info structure.
2125 Added optional CCL (ISO8777) interpreter as separate module. Available
2128 --- 1.2 1996/6/10 (1st anniversary release)
2130 Added Summary record syntax. Lightly tested.
2132 Added OPAC record syntax. Untested.
2134 Added ResourceReport service encoders/decoders. Untested.
2136 Fixed bug in z_Unit - wrong tagging on unitSystem.
2138 Fixed bug in the DiagRecs decoder.
2140 Added options for max PDU size and session timeout to frontend-server.
2142 Added documentation of query-language parsers and other supporting utilities.
2144 [frontend-server] Added Attribute set to the bend_scanrequest API.
2146 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2147 surrogate diagnostics were generated.
2149 [retrieval] Allow multiple local values for attribute.
2151 [retrieval] Allow multiple attributes per element in .abs files. index type.
2153 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2155 --- 1.1pl2 1996/4/10
2157 Minor changes, mostly specific to Zebra's requirements (retrieval)
2161 Repaired bug in frontend server when running multiple listening
2162 endpoints in dynamic mode.
2164 z_External() now won't break if a known, ASN.1 value comes encapsulated
2165 in an octet-string. The value will pass through unmodified in an Odr_oct.
2167 Added a bit of code to the demo client to decode & display
2168 ASN.1-structured records represented in the octet-aligned branch of
2169 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2171 Added z_ext_getentbyref() to the ASN module. Doc updated.
2173 * Completed the SCAN definition in the ASN module. This may break SCAN
2174 code based on older YAZ-versions at compile-time. The fix is easy -
2177 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2178 under the SCAN definition. Remember to initialize this, server-people.
2180 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2181 that this does not extend to ODR and ASN.
2183 Comstack allows insertion of established socket (primarily for
2184 inetd-operation of servers). Doc updated.
2186 Front-end server can now start from the inetd in TCP mode. Doc
2189 --- 1.0pl4 1996/1/24
2193 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2194 the rank and record number.
2196 Adjustments to the frontend server.
2198 Fixed diagnostic BER dumper. It ignored the file argument.
2202 Various changes to retrieval module.
2204 Changed the union discriminators of the protocol files from enums to
2205 ints paired with #defines.
2207 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2210 *Changed operator in the RPN structure to 'roperator', again to avoid a
2213 Fixed problems in Explain decoders/encoders.
2215 --- 1.0pl2 1995/12/6
2217 Memory bug in log module fixed.
2219 --- 1.0pl1 1995/12/5
2221 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2223 Bug in Explain DatabaseInfo module fixed.
2225 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2229 The shift to v1.0 signals that we now consider the *core* functionality
2230 of YAZ reasonably stable (the core being more or less equivalent to
2231 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2232 tested (Explain not at all - though that will happen soonish).
2234 Minor changes to code to support Windows port.
2236 Various minor changes after we're getting to use GRS-1 & co. more.
2238 Added Espec-1 format.
2240 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2241 of the protocol and it cannot be selected when encoding (maps into 'string'
2242 when decoding). Needed to talk to some servers.
2244 Demo client can request simple element set names.
2246 Added Diagnostic Format encoders/decoders.
2248 Added simple Close handling to frontend server (no hooks for resource
2249 reporting yet), and demonstration client.
2251 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2253 --- 1.0b3 1995/08/24
2255 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2256 handled incorrectly when records were requested in the searchResponse. This
2257 will only affect you if you use the frontend-server.
2259 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2260 Test-client will ask for and print GRS1. Ztest will return dummy records
2263 Added Explain encoders/decoders to the service-level API. Untested.
2265 Added Extended Services: Item Order encoders and decoders to the Service-
2266 level API. Untested. We could use a recent copy of the pertinent bits
2267 of the ILL protocol to add those bits.
2269 Added diagnostic format 1 encoders/decoders to the service-level API.
2272 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2273 odr_cons.c, which causes a more correct output.
2275 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2276 was always set to 0 when no records were requested in the searchRequest.
2278 * Added better external-handling. This shouldn't harm old code that
2279 *encodes* externals. It can break code that looks for a
2280 'single-ASN1-type' representation, since those types that are known
2281 are now decoded immediately. Look at the SUTRS sample code in
2282 seshigh.c and client.c. Documentation updated.
2284 Handling of structured records in bend_fetchresponse. Length -1 marks
2285 structured record, type is deduced from format field.
2287 --- 1.0b2 1995/06/27
2288 Fairly quick maintenance release to add SUTRS support.
2290 Fixed handling of SUTRS records in the demonstration client.
2292 * Added format field to the bend_fetchrequest and bend_fetchresponce
2293 structures of the backend API (frontend server). When the record is
2294 returned, the value of the format field is mapped to an OID. The
2295 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2296 of the record. The special value VAL_NONE in the bend_request means
2297 that no specific format was requested by the client. Documentation
2298 updated accordingly. Test server (ztest) will return a fixed dummy
2299 SUTRS record if your client requests SUTRS.
2301 Documentation updated accordingly.
2303 You can now set external libraries and RANLIB support in the top-level
2307 First public release.
