1 Added support for SRU scan.
3 Added support for the use of the older versions or Extended Service
4 Update in ZOOM. To faciliate this, an option "updateVersion" may be
5 set to the version , 1=first, 2=second, 3=third. The third version is
6 what ZOOM C has used so far. And that, obviously, is the default.
8 Added support for CCL queries in Z39.50 queries sent to the GFS (and
9 therefore in Zebra and in SimpleServer-based applications). The new
10 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
11 qualifier file used to transform incoming CCL queries into Type-1 RPN,
12 which is passed into the back-end search callback function.
16 Fixed bug #1208: SSL appears to be broken in ZOOM.
18 Fixed bug #1206: Libxml2 include path weirdness.
20 Added oid_name_to_dotstring.
22 Allow elementSetName to be specified for ZOOM C record update.
24 Allow waitAction to be specified for ZOOM C based for Extended Services.
26 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
27 syntax OID. Bug introduced in YAZ 3 series.
29 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
33 Fixed bug #1157: yaz-client does not read .yazclientrc from current
34 directory. yaz-client now reads commands from file given by option -f
35 if specified; then tries to read .yazclientrc in current directory.
36 Failing that, it reads .yazclientrc from user's home directory.
38 Added support for correlationInfo Note and ID for Record Update via
41 Added yaz-client command querycharset which specifies character set for
42 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
43 (termListAndStartPoint).
45 Charset ISO5428:1984 is an alias for ISO5428-1984.
47 Implemented a way to perform scan in a result set using Z39.50. This
48 is achieved by attaching the result set name in the characterInfo
49 (type InternationalString) of OtherInformation in the Scan Request PDU.
50 The result set is identified in the otherinformation by the new OID:
51 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
52 This allows for scan in result set and faceted search . Zebra did some
53 of this in the APT term using attribute type 8 and value being result
54 set. Using the OtherInformation approach for this is cleaner and easier
55 to work with in proxies and the like. This facility can be used in
56 yaz-client using new command setscan which takes a result set as first
57 argument, start position (APT) as second.
59 Changed decoding of SRU XML packed records to deal with servers that
60 have recordData with XML data with multiple root nodes. Also make
61 comparison for recordPacking case insensitive. Again, one server
62 returns "XML" where others return "xml".
64 For SRU responses allow Content-Type application/xml as well as text/xml.
68 Fixed bug in character set conversion of BER strings. Bug introduced
73 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
75 For OID class, use oid_class consistently.
77 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
80 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
81 character set for bibliographic information interchange". By Giannis Kosmas.
83 Added documentation on new OID API.
87 Changes to generic frontend server interface: added new member
88 'query_charset' for bend_initrequest structure. A backend init handler
89 should set this member to its native character set for query terms.
90 When defined, the frontend server logic will announce this character set
91 to a client if the negotiationModel bit is set by the client. All server
92 implementors are encouraged to specify this. If a backend server does not
93 specify this a warning is issued using yaz_log(YLOG_WARN,..).
95 Added CCL utility to remove terms (stop words) from resulting RPN
96 tree. This is handled by functions with prefix ccl_stop_words_ .
98 New ZOOM C option, "rpnCharset", which allows client-side conversion of
101 Clean-up the CCL API. Moved some internal structures from ccl.h to
102 private header cclp.h. Changed ccl_parser_create so that a Bibset must
103 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
104 This is replaced by ccl_parser_find_str which takes a string instead.
106 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
107 libyaz.la is the core of YAZ except the generic frontend server and
108 does not depend on POSIX threads anymore. libyaz_server.la is the
109 generic frontend server facilities and uses POSIX thread functionality
110 if available. The libyaz.la no longer depends on POSIX threads because
111 the number of global structures is limited. NMEM no longer re-uses blocks
112 between threads ; it simply free's memory immediately but allocates in
113 "large" chunks as usual. We don't expect any performance penalties
114 because of this. The yaz_log system is still using a global log_level so
115 caution must be taken when modifying it with yaz_log_init_.. +
116 yaz_log_mask_str. This, however, should not cause any trouble because
117 these functions are called during initialization of application code
118 anyway. `yaz-config --libs server` returns libs for server applications;
119 `yaz-config --libs` returns libs for non-server applications.
121 New OID database - with public definitions in oid_db.h. Removed old OID
122 database including the head oid.h and definitions such as enum oid_value
123 and struct oident. The new OID database uses the same string names as
124 before but the 'protocol' is gone. There are now only two representations
125 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
126 converts from string to OID; functions with prefix yaz_oid_to_string
127 converts the other way.
129 Change to emit_term() in CQL-to-PQF query translation: when a term has
130 the /regexp relation modifier, do not process it for leading and
131 trailing "^" and "*", which have quite different meanings in regular
134 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
135 write handlers no longer carries a 'last' parameter. This will make
136 yaz_iconv flush "less" characters. A flush is performed by call to
137 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
139 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
140 removed, because function yaz_query_to_wrbuf does the same.
142 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
143 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
145 Deprecated MARC utility functions removed.
147 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
150 Branch split: YAZ_2_1_55_branch
152 --- 2.1.54 2007/03/16
154 Fix to ZOOM-C so that transparent reconnection is properly handled on
155 connections that are in asynchronous mode.
157 Fixed compilation on OpenBSD 4.0.
159 Large strings in GRS-1 records are now properly displayed in yaz-client.
161 Added character conversion support for "advancegreek"; based on patch from
164 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
165 sequence is met. Before the error was not set so it would be unknown.
167 Adjust yaz-marcdump MARC reader so that it skips until record separator
170 --- 2.1.52 2007/03/07
172 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
173 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
174 fd_set structure used as a bitmask for the FDs to be selected on.
176 Using ACX_PTHREAD macro to check for POSIX threads.
178 Fixed have-vsnprintf check.
180 --- 2.1.50 2007/02/23
182 Fixes for configure on BSD. Bug #900.
184 Added snprintf/vsnprintf wrappers for systems that don't have
185 limits (heavens forbid).
187 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
188 created before all previous tasks were completed and removed from the
189 task queue, the new task could be removed by a mistake.
191 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
193 Implemented pass-through CQL-to-PQF conversions. Bug #861.
195 Fixed bug #832: Problem with MARC/charset in yaz-client.
197 Fixed bug #668: save command line history for yaz-client.
199 Fixed bug #830: pkg-config support.
201 --- 2.1.48 2007/01/23
203 Extended ZOOM result set options with two options that may be read by
204 a client: resultSetStatus and presentStatus with values as specified for
206 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
208 Fixed bug #827: Using SSL fails on Debian etch.
210 Fixed bug #826: Weird looking chars for set of MARC records.
212 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
213 that is treated as an ItemOrder with itemRequest being an XML document
214 external. The value of "doc" is the content.
216 Extended the GFS search facility. New member of bend_search_rr
217 'estimated_hit_count' signals that hits is known to be an estmate
218 (higher or lower than real hit count). New member 'partial_resultset'
219 signals that the search was partial (hit count is lower or equal than
220 real hit count). For Z39.50, the information is stored in resultSetStatus
221 member of SearchResponse APDU. For SRU, the information is signalled
222 via SRU diagnostic 59: "Result set created with valid partial results
225 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
227 --- 2.1.46 2007/01/13
229 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
231 Added ZOOM_connection_peek_event.
233 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
234 the following new functions:
235 ZOOM_event_nonblock, ZOOM_connection_process,
236 ZOOM_connection_get_{socket,mask,timeout},
237 ZOOM_connection_fire_event_{timeout,socket}.
238 The existing blocking event handler, ZOOM_event, is a wrapper for the
239 + blocking ZOOM_event_sys_{poll,select}.
241 Implemented function ccl_xml_config which parses XML version of CCL
242 configuration (bug #798).
244 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
246 Added timings utility (yaz/timing.h)
248 --- 2.1.44 2007/01/03
250 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
253 Fixed bug #779: Rotation of apdu.log fails.
255 Fixed for character set conversions:
256 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
257 Honor G1 set in MARC-8 decoding.
259 --- 2.1.42 2006/12/17
261 Fixed bug #775: char conversion does not handle Alternative UTF-8
264 Implemented function yaz_marc_read_line which parses MARC line format
265 records. There is a wealth of formats out there. So far, this function
266 reads line records produced by yaz_marc_write_line.
268 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
269 more generic and easier to remember(!) options: -i format and -o format
270 which specifies input format and output format respectively - where
271 format is one of "marc", "marcxml", "line", "marcxchange".
273 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
274 does not print anything except warnings for records.
276 For yaz-marcdump, added support for MARC split into files (-s) with a given
279 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
280 spec, at http://www.loc.gov/standards/sru/record-update/
281 This has changed the binary layout of the following structs:
282 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
283 bend_update_rr . Patch by Ko van der Sloot.
285 Added GFS utility function bend_assoc_is_alive which returns 1 if
286 association is still alive (client is connected); 0 otherwise (client
287 closed connection). This allows busy servers to stop working for
290 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
291 been a separate piece of software. This version of ziffy has been modified
292 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
294 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
296 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
297 Client code may now interrogate options such as "init_opt_sort" to
298 find out whether the server claims to support various options.
300 --- 2.1.40 2006/11/27
302 Added utilities yaz_{set,get}_esn to set/get element set name from
305 Removed the build of libyazthread.la. The libyaz.so is the threaded version
306 of YAZ and has been so since YAZ 2.1.10.
308 Implemented ZOOM_record_error which returns error information for
309 record (surrogate diagnostic).
311 --- 2.1.38 2006/10/31
313 Updates for SRU Update by Ko van der Sloot:
314 1. Changed name from "operation" to "action"
315 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
316 versions in the code, marked as 'backward compatible'.
317 3. Added diagnostics for SRU Update.
319 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
321 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
323 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
325 For GFS, fixed problem with SRU diagnostic 'First record position out of
326 range' being issued for 0 hits.
328 zoomtst10 part of Windows Build.
330 --- 2.1.36 2006/10/13
332 Implemented yaz_filepath_comp which splits a path into file path
333 components (required by Zebra 2.0.3+).
335 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
336 BSD inspired license until now so this should not have any real impact on
337 anybody. See http://www.opensource.org/licenses/bsd-license.php
339 Fixed bug #687: Missing log lines.
341 Fixed bug #678: CQL to PQF translation does not preserve double-quote
344 Fixed bug #689: SRU diagnostics to be added.
346 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
347 whether a connection is idle (no more work do do).
349 --- 2.1.34 2006/10/04
351 Change type of optval from long to int for invocation of setsockopt with
352 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
354 Added support for specifying the max log file size for the Generic
355 Frontend Server. The size is given with option -r.
357 --- 2.1.32 2006/09/21
359 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
361 --- 2.1.30 2006/09/17
363 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
366 Fixed bug in Generic Frontend Server that could cause a server to stop
367 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
369 For the generic frontend server, the maximum record size is used as maximum
370 size of incoming packages (SRU + Z39.50). The value until was previously
371 only used in Z39.50 Init negotiation and, later, in a session controlled
372 sizes of records returned. This is controlled using -k option. It can be
373 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
375 --- 2.1.28 2006/09/04
377 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
380 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
382 New option for yaz-marcdump -lpos=value which allows setting a portion
383 of MARC header to a certain value.
385 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
387 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
388 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
390 --- 2.1.26 2006/08/15
392 Fixed problem with SRU mode type (soap, get, post) for yaz-client
395 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
397 --- 2.1.24 2006/08/08
399 Fixed MARC ISO2709 encoding routines to deal with character set
402 Minor changes to GFS logging. Database included in search request log
405 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
406 cached/multiple records.
408 Shared libraries are built by default on Unix+configure.
410 Changed cql2pqf transformation to use a different evaluation order. The
411 new order is: always, relation, structure, position, truncation, index
412 and relationModifier. Old order was: always, relation, relationModifier,
413 structure, index, position, truncation. Note that the the latter ones
414 override former ones for identical attributes.. The new scheme means that
415 it is possible to override any existing attribute with a relationModifier.
416 And also that it is possible to override everything for the index rule
417 (except the ones listed in relationModifier). No order is perfect but this
418 one, we believe, covers more real cases.. The "always" should have been
419 called "default", since the attributes there can be overridden with all
422 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
423 compilation phase, but also for yaz-config --cflags output. This allows
424 us to have public headers with Libxml2 stuff in them . It should also,
425 eventually, make Libxml2 checks redundant in packages using YAZ, such
428 --- 2.1.22 2006/06/15
430 Changed SRU update structure bend_update_rr so that SRU diagnostics are
431 stored in uri, message and details.. Previously diagnostics were stored
432 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
433 compatibility.. but he's probably the only one affected, so.
435 Added support for CCL, compiled on the client side, in ZOOM-C. This
436 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
437 input; the resulting query objects can be used for for searching with
438 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
440 YAZ' configure searches for OpenSSL by default.
442 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
443 SL_CTX_use_certificate_file. See
444 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
445 for more info. Thanks to Ko van der Sloot.
447 --- 2.1.20 2006/06/02
449 Bug #600: SRU GET, POST support for yaz-client. Introduced
450 command 'sru' which selects method SOAP/GET/POST.
452 Allow missingValueAction to be specified for the sortspec string -
453 function yaz_sort_spec. By default, the missing value action is null.
454 Use ! to specify "abort". Use = followed by stringvalue to specify default
457 Ensured that Present-handler (if defined) is called in GFS before any call to
458 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
459 searchRetrieve requests.
461 Documentation for YAZ is now based on the Docbook XML/XSLT using
462 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
463 is no longer depending on jade/openjade or docbook-to-man scripts.
464 PDF is no longer part of the distribution - but can optionally be
465 made using DSSSL/jadetex or FOP.
467 Added retrieval handling support in Generic Frontend Server to support
468 conversion between MARC/XML as well as XSLTtransforms. See
469 etc/yazgfs.xml for an example.
471 Added Authentication support to Generic Frontend Server in SRU
472 mode. Authentication using HTTP Basic is supported, as is the use
473 of 'x-username' and 'x-password' parameters in the request itself.
475 Added support for a new character set MARC8s identical to MARC8 except
476 that it converts combined characters to single Unicode characters in the
477 Latin-1 range (when possible).
479 --- 2.1.18 2006/04/24
481 ASN.1 compiler 0.4: generates brief Doxygen file header for
482 generated .h/.c files.
484 Utility yaz_iconv now supports conversion to MARC-8.
486 New facilities for the MARC module. The reading - and writing of
487 content are separate methods for the yaz_marc_t handle. The following
488 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
489 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
490 format). Write functions have prefix yaz_marc_write_.. The existing
491 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
492 available. Removed support for OAI-MARC and simplexml (not the
493 simplexml from PHP5).
495 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
496 to be returned for this connection.
498 --- 2.1.16 2006/03/31
500 Allow multiple languages and charsets to be specified with
501 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
502 negcharset iso-8859-1,utf-8
504 Translation of proximity nodes from CQL into PQF now works.
506 Moved to automake 1.8, 1.9.
508 Added function yaz_log_set_handler which allows a log handler to be
509 installed. This handler will be called for all log messages. Output
510 to file is also produced; but that can be disabled by passing NULL
511 fname to yaz_log_init_file.
513 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
515 For SRW (including GFS), accept application/soap+xml as content-type
518 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
519 produces NO stylesheet reference even if a default stylesheet is specified
522 --- 2.1.14 2006/03/14
524 Updated Windows package to include yazd.dll + yazd.lib for the
525 Development component.
527 If the environment variable YAZ_LOG is set, then it is used as a
528 string indicating the default level of logging to use if not
529 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
530 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
531 used as before. So, for example, to omit warnings from YAZ logging,
534 cql_transform() now map structure and other attributes before indexes,
535 so that index-specific structures and other attributes can override
536 defaults. So now a combination of mapping specifications such as:
538 index.dc.date = 1=date-modified 4=5
539 does the right thing.
541 cql_transform() now also respects the "always" mapping specification,
542 which establishes an initial set of attributes to be used for all
543 terms except where overridden by more specific attributes associated
544 with the index, relation or modifier.
546 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
547 which mode to use; one of "post", "get" or "soap" (SRW, default).
549 Fixes for yaz_iconv routines: changed trie-based character set conversions
550 to use only non-negative values for bit fields due to Sun's C compiler not
551 supporting negative values.
553 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
554 sequences where not read correctly. Fix by Rustam Usmanov.
556 Updated win/makefile to use options, settings which makes things
557 compile with VS C 2005.
559 --- 2.1.12 2006/02/01
561 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
563 In ZOOM socket code, use select instead of poll on MacOSX.
565 ZOOM-C now support client-side compilation of CQL into RPN that is
566 sent to the server, enabling CQL to be used against all Z39.50
567 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
568 ZOOM_query object, and submit it using ZOOM_connection_search().
569 The CQL-to-RPN translation uses a configuration file, the name of
570 which must be specified in the Connection's "cqlfile" option.
572 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
573 function, which takes as its start-term parameter a ZOOM_query object
574 (which may have had either CQL or RPN set into it).
577 --- 2.1.10 2005/11/29
579 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
580 GFS to support this as well. Backend handler, bend_srw_update, does the
581 update work. Code contributed by Ko van der Sloot.
583 Allow retrieval of Search Result-1 information in ZOOM by the use of
584 options that are attached to a result set. ZOOM documentation updated
587 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
588 UTF-8 conversion. Patch by Raj Patel.
590 Added option -m to GFS to control formatting of timestamps in log file.
592 Added 'exit' as synonym for 'quit' in yaz-client
594 Added support for specifying SRW resultSetId + resultSetIdleTime in a
595 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
596 for the new members. Patch by Ko van der Sloot.
598 Added support for SRU POST. It is supported for content-type
599 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
601 Do not build the separate Multi-threaded (MT) library libyazthread.la.
602 Instead make the library libyaz.la multi-threaded. Threading as a whole
603 can still be disabled by configure option --disable-threads. Previosly,
604 with older GLIBCs there were problems with MT libs under Apache. This
605 has now been fixed a long time ago.
607 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
610 CQL module modified to be case insensitive for relations/indexes/operations.
612 Fixed bug in CQL transform code: incorrect value relationModifieder
615 Added 'show all' command for yaz-client which retrieves all results
618 Added new yaz-client, xmles, which takes a (private) OID and
619 a document to be sent as an extended service request.
621 Describe new yaz-client commands wait_response and set_auto_wait.
623 Increase TCP/IP listener backlog from 3 (which I am guessing was
624 copied from the SunOS manual entry way back when) so SOMAXCONN, so
625 that the socket will queue as many incoming connections as it's able
626 to handle ongoing connections. In other words, it will never now
627 refuse a connection that it would be able to handle merely because
628 it's not got around to accepting() enough of the pending connections
629 yet. This is the behaviour anyway under Linux, where the listen()
630 argument is ignored; but not under BSD and on systems such as
631 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
632 YAZ-based servers should now be uniform across operating systems in
635 yaz-marcdump uses 64-bit file access on some systems. This is enabled
636 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
637 This allows yaz-marcdump to read large MARC batches (>2 GB).
639 Modified all YAZ source files - except the source which is auto-generated
640 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
643 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
644 corresponding to the existing *_setl() function. These allow option
645 values containing arbitrary valuues.
647 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
648 ZOOM_resultset_sort() in new applications. Its behaviour is identical
649 except that it returns an indicator of whether or not the sort
650 criterion was accepted (0 for OK, -1 for invalid).
654 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
655 MARC output rather than returning "new" buffer.
657 yaz-client warns about unknown init options.
659 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
663 Added support for SRW sort in Generic Frontend Server. Patch
664 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
665 sortKeys - or NULL if none is provided.
667 Fixed bug #307: It was impossible to specify indefinite/no timeout
668 for ZOOM_event. Special timeout value -1 now means indefinite timeout
671 Added support for multiple languages and charsets to be specified in
672 ZOOM. Each charset/language is separated by a blank. If negotiation is
673 in effect in init-response, Option
674 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
675 Code based on patch by Vasiliy Osadchuk.
677 Fixed bug #306: infinite recursion that occurred when calling
678 yaz_log_level_init as the first call (before other log level or
681 Fixed bug in scan handling in front end server: if preferred-Position-In-
682 Response was non-present, a NULL pointer referece was performed.
686 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
687 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
688 now defined for all those error codes. So instead of putting 109 in
689 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
690 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
692 Modified the yaz-marcdump utility to skip garbage bytes between MARC
695 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
697 Program yaz-client now exits and produces an error message if multiple
698 Z39.50 servers are specified on the command line (none or one allowed
701 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
706 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
708 Fixed bug #272: Preserve spacing for CCL terms.
712 Added support for virtual hosts and multiple backend servers for
713 the YAZ frontend server. The configution is XML based and
714 support specificition of CQL to RPN mappings and explain information.
715 See section "Virtual Hosts" in the YAZ manual.
717 Extended OPAC display utility. OPAC display utility renders
718 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
719 to supplement yaz_marc_decode_wrbuf.
721 Fixed a bug in MARC decoder that could caused it to crash for some
722 invalid MARC records. More diagnostics and warnings where added in
723 XML output (warnings, etc are stored in comments).
725 --- 2.0.34 2005/02/08
727 Fixes for UNIX domain sockets. Bug #261.
729 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
731 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
732 Added yaz_marc_subfield_str which defines subfield lead string which is
733 used in YAZ_MARC_LINE format. Default string is blank+$. Added
734 yaz_marc_endline_str which defines end of fields string used in
735 YAZ_MARC_LINE format. Default string is newline.
737 Experimental support for MarcXChange. This format can be produced
738 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
739 http://www.bs.dk/standards/MarcXchange.xsd
741 Added yaz-client commands scansize that sets maximum number of
742 entries to be returned by scan.
744 --- 2.0.32 2005/01/11
746 Added support for SRW scan in yaz-client and Generic Frontend Server.
748 * Added whereInList member to SRW Scan Term.
750 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
752 Fixed NMEM system to return aligned blocks on the smallest boundaries
753 that are suitably aligned for all possible types on the particular
754 architecture YAZ is being built for.
756 --- 2.0.30 2005/01/04
758 Fixed numerious warnings that was issued with newer versions of GCC.
760 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
761 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
764 Make YAZ Generic Frontend Server slightly faster.
766 Enhance (and reduce) logging for Generic Frontend Server.
768 Revert YAZ log system so that it flushes every write operation
769 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
771 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
772 instead of LOG_, due to name clash with syslog(3). LOG_ are still
773 present. New applications should define YAZ_USE_NEW_LOG=1 - this
774 will effectively disable old definitions.
776 --- 2.0.28 2004/11/09
778 Added yaz_log_time_format which specifies log format using
781 Added yaz_log_module_level which returns mask for a module. Value
782 is non-zero mask a if module is enabled; zero if disabled.
784 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
785 in include/yaz/cql.h.
787 Fixed bug #176: Dont throw diagnostics on empty SRU args.
789 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
791 Fixed bug #172: RPM builds does not enable SSL.
793 Doxyfile.in part of dist. Doxyfile generated by configure.
795 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
796 are given and the corresponding component does not exist.
798 Extend CCL documentation in YAZ reference. Describe r=r.
800 --- 2.0.26 2004/10/01
802 Fixed MARC->MARCXML conversion to properly deal with
803 fields, subfields, indicators having non-ASCII characters.
805 Fixed MARC->MARCXML conversion so that ASCII control characters
806 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
809 Added YAZ GFS support for conversion from Z39.50 surrogate
810 diagnostics to SRW surrogate diagnostics.
812 Bug fix: YAZ GFS did not return schema in explainResponse.
814 --- 2.0.25 2004/09/30
816 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
817 now converts recordSchema to elementSetName as well as schema URI.
819 Fixed bug in COMSTACK that prevented HTTP request packages from being
822 --- 2.0.24 2004/09/29
824 Added CCL facility r=r "range" which is similar to r=o "ordered" but
825 does not require white-space before and after the dash in a range, e.g.
826 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
829 Fixed a few AC_TRY_LINK configure tests that did not operate properly
830 due to new GCC removing "redundant" code.
832 Added yaz-client commands scanpos and scanstep that sets preferred
833 position and step-size for scan.
835 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
837 Added CCL utility ccl_qual_buf which parses one or more CCL
838 spec lines in a buffer.
840 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
841 of name and value - ignoring empty lines and comments.
843 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
845 Added odr_get_element_path which returns current element path for an
846 ODR handle. This utility is useful in error handling or user-defined
849 Added ODR_PRINT utility odr_set_stream which is is a more generic
850 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
851 to a write function and pointer to close function. The close function - if
852 non-NULL - will be called during odr_destroy.
854 Fixed bug in CCL parser where truncation char was not removed from
855 right side when truncation=both was in effect.
857 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
860 --- 2.0.23 2004/08/11
862 Fix buffer overrun in CQL parser when dealing with proximity (%).
864 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
865 to UTF-8/UCS conversion is now only based on codetables.xml.
867 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
869 --- 2.0.22 2004/08/06
871 Add support for more "commit changes" in ZOOM (uses Extended Services).
873 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
876 Yet another small fix for configure of SSL.
878 --- 2.0.21 2004/05/14
880 Fix SSL libs for configure when --with-openssl=DIR is given.
882 --- 2.0.20 2004/05/10
884 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
886 SSL comstack now uses yaz.pem certificate file on server side
887 by default. Certificate filename can be configured by calling
888 comstack function cs_set_ssl_certificate_file before cs_bind is used.
890 Fix bug regarding multiple calls to ZOOM_connection_connect.
892 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
894 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
895 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
897 ZOOM now allows inspection of X509 peer certificate for verification.
898 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
900 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
901 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
902 as "modular" but it simplifies things.
904 Added cs_get_peer_certificate to that returns peer X509 PEM.
906 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
907 NULL if SSL is unavailable.
909 Documentation about MARC decoding tools.
911 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
913 --- 2.0.19 2004/03/30
915 Rename CHANGELOG to NEWS to follow GNU style packing.
917 Fix bug with missing initialization of member in init_diagnostics.
918 This bug affects threaded version of GFS server.
920 --- 2.0.18 2004/03/20
922 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
925 Ensure zlib.dll is packed with Windows install.
927 --- 2.0.17 2004/03/17
929 Fix encoding of xsd:string to use text instead of CDATA.
931 Fix endless loop in CQL parser with unbalanced ".
933 Use a more compact way to store MARC-8 conversion tables.
935 --- 2.0.16 2004/03/16 Debian only
937 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
940 Update CQL parser to use new CQL 1.1 modifiers for booleans and
945 --- 2.0.15 2004/03/01
947 Another fix for decoding of XML packed records.
949 --- 2.0.14 2004/02/25
951 Fixes for Chunked encoding. White space not ignored after length spec.
953 Update NS and use default NS for SRW diagnostic elements.
955 --- 2.0.13 2004/02/23
957 Implement ZOOM_resultset_cache_reset which resets record cache.
959 Implement ZOOM_resultset_sort which sorts a result set.
961 Implement chunked HTTP transfer.
963 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
965 --- 2.0.12 2004/02/16
967 Added member 'schema' to bend_explain_rr structure so that backend
968 can specify explain record identifier. Defaults to Zeerex 2.0.
970 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
972 --- 2.0.11 2004/02/16
974 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
977 Added init command for yaz-client which sends "extra" init request.
979 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
980 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
982 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
984 Make ZOOM error code for "invalid query".
986 Fixed compilation for SSL which wasn't properly enabled for all platforms.
988 --- 2.0.10 2004/02/05
990 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
993 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
995 Added option -p <file> to make Generic Frontend Server to write PID file.
997 Added option -D to put Generic Frontend Server in background on its own.
999 Make ZOOM C recognize option "password". If unset, "pass" is used
1000 (for backwards compatibility).
1002 Fixed a bug in Generic Frontend Server that could make it crash if a
1003 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1006 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1007 Must be issued before open, in order to be in effect.
1009 --- 2.0.9-6 2004/01/12 Debian/Windows
1011 Make the SRU server more picky WRT unknown params, etc.
1013 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1015 New YAZ client command, options, that sets Z39.50 options.
1017 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1018 options from a string of tokens (one token for each option bit).
1020 Update SRW diagnostic code messages.
1022 --- 2.0.9-5 2004/01/07 Debian/Windows
1024 Handle user defined stylesheet for SRW/SRU.
1026 --- 2.0.9-4 2004/01/06 Debian/Windows
1028 Fix bug in decoding of Content-Length.
1030 --- 2.0.9-3 2004/01/06 Debian/Windows
1032 Fix a bug with decoding of XML packed records.
1034 --- 2.0.9-2 2004/01/05 Debian only
1036 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1038 Fix bug in SRW/SRU diagnostics decoding.
1040 --- 2.0.9 2004/01/05
1042 Fixed bug in Generic Frontend Server which could drop records exceeding
1043 preferred message size. Reported and fixed by Irina Dijour.
1045 Fixed calculation of package size for structured records in Generic
1046 Frontend Server. Reported and fixed by Irina Dijour.
1048 Fixed namespace for SRW/SRU diagnostics.
1050 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1052 --- 2.0.8 2003/12/22
1054 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1055 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1058 CQL changes to reflect recent changes to the specification:
1059 * Documentation talks about context sets instead of index sets.
1060 * Documentation talks about indexes instead of qualifiers.
1061 * The CQL-to-PQF transformer's configuration file now uses
1062 "index.set.name = <attributes>" instead of the old form
1063 "qualifier.set.name = <attributes>". (Both forms are still
1064 understood but the latter is deprecated.)
1065 * CQL terms with no explicit index specified are now interpreted as
1066 cql.serverChoice instead of srw.serverChoice (which of course
1067 behaves exactly the same.)
1069 --- 2.0.7 2003/12/16
1071 MARC conversion can now generate ISO2709 output in another
1072 character set. yaz-marcdump uses this facility if you invoke it
1075 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1076 functions from there can be used from C++.
1078 --- 2.0.6 2003/12/04
1080 Frontend server now transfers memory from decoded packages to stream
1083 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1084 references to show up.
1086 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1087 the ZOOM Abstract API. The older names for the same options are still
1088 also supported for the benefit of old applications.
1090 ZOOM-C supports "implementationId" and "implementationVersion" options
1091 to go along with "implementationName". These allow the user code to
1092 specify identification strings to be sent to servers.
1093 Add OID for the new ExtLite attribute set.
1095 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1096 as requested/supplid by Ere Maijala <ere@atp.fi>
1098 For generic frontend server, reverse the order of
1099 "toolkit-supplied / application-supplied" strings sent as implementationId,
1100 Name and Version. Also, remove the spaces around the slash. This brings
1101 the GFS in line with the behaviour of ZOOM-C on the client side.
1103 Add function ZOOM_scanset_display_term.
1105 yaz-client shows scan displayTerm if present.
1107 Utility yaz-iconv is now installed by default along with the man page
1110 Extend configure check for OpenSSL to use pkg-config where available (such
1113 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1114 server to specify uid/gid/mask for socket using the format
1115 unix:[user=uid,][group=gid,][umask=mask,]file=path
1116 If file= is omitted the existing format is assumed, e.g.
1118 in which case the mask is 0666 (rw for everybody).
1120 Major restructure of YAZ source. All source in libyaz is in src directory.
1121 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1122 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1124 Added man page for utility yaz-marcdump (used to be called marcdump).
1125 yaz-marcdump is installed by 'make install'.
1127 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1128 of incoming package failed.
1130 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1132 Change prototype of odr_perror: add const to message string.
1134 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1136 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1137 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1138 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1139 DNS lookup. There should not be any compatibility problems with this
1140 assuming that blocking=1 or 0 is used.
1142 Fix bad reference in UNIX comstack in function cs_addrstr.
1144 Fix for compilation on AIX.
1146 The generic front-end server (server/seshigh.c) now supports returning
1147 Init diagnostics to the client in User-information-field, in
1148 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1151 --- 2.0.4 2003/09/04
1153 Allow any CQL relation (not just all,any,exact,scr).
1155 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1156 that features the same UI.
1158 Implemented command update0 in YAZ client which is equivalent to
1159 update but uses old of Ext Update ASN.1.
1161 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1162 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1163 Previously no OID was used for this info.
1165 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1166 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1167 returns 'malformed search term' otherwise.
1169 SortResponse member resultCount now set to NULL in sort handler of
1172 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1175 Add three new utility functions for translating OIDs between various
1176 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1177 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1178 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1179 char *oid_to_dotstring(const int *oid, char *oidbuf);
1180 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1182 Reverted modifications for ES Update definition for z_IU0Update
1183 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1184 is back to YAZ 2.0.2.
1186 String value attributes for CCL parser.
1188 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1189 which their FirstSearch server returns in Init responses, sometimes
1190 carrying useful diagnostic information when Init fails. This has the
1191 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1192 "z39.50/oclcui.asn", where its definition is somewhat different from
1193 what OCLC document on their web-site, as required to interoperate with
1196 Support for anonymous authentication in yaz-client. Use the command
1199 * Fix the OID of the Index Data-local "admin" Extended Service from
1200 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1201 the 1000, which indicates a locally-defined OID, was a mistake.
1203 --- 2.0.3 2003/06/20
1205 Fix CCL directive @case handling so that it affects string match for
1206 both CCL keywords and qualifiers.
1208 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1209 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1210 Decoder has been updated with ASN.1 changes as listed in
1211 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1212 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1213 z_IUUpdate, remains unchanged.
1215 ZOOM_record_get may now return a record in a specific character set.
1216 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1217 "from" is the character set of record as returned by target. "to" is
1218 the character set to be returned. If omitted, "to" is UTF-8.
1220 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1222 New ODR utility, odr_getelement, which returns name of element for
1223 which encoding/decoding failed.
1225 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1226 in cases where a required element was omitted.
1228 Bug fix: some MARC8 sequences were not converted.
1230 New ZOOM option "step" which specifies number of records to be
1231 retrieved in one chunk. Used in conjunction with "start" and "count".
1233 SRW support for yaz-client. Use scheme http: to use it, e.g.
1236 yaz-client no longer does (un)intelligent character set conversions
1237 by default. Can be enabled with charset and marc_charset commands.
1239 xmalloc trace fix for 64-bit systems such as DEC alpha.
1241 Solaris 2.6 compile fix.
1243 New function, cql_strerror() translates SRW error codes, as returned
1244 by cql_transform_error(), into human-readable English strings. Used
1245 in yaz-client diagnostics when appropriate.
1247 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1248 converts it into a type-1 query which is sent to the server. This
1249 makes CQL available for use with all Z-servers, as opposed to the tiny
1250 minority that can handle CQL queries themselves.
1252 --- 2.0.2 2003/04/28
1254 New Debian package layout similar to the Redhat Package layout.
1256 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1257 and search result respectively.
1259 --- 2.0.1 2003/04/25
1261 Redhat package is now several packages: libyaz (runtime libraries),
1262 libyaz-devel (development and documentation, and yaz (utility programs).
1263 Package spec file by Morten Bøgeskov.
1265 New member 'schema' in struct bend_fetch_rr which the name of requested
1266 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1267 handler MAY set this to reflect the schema of the returned record.
1269 New member 'display_term' in struct scan_entry. GFS now sets member entries
1270 and allocates scan entries to be filled by user scan handler. In previous
1271 version, entries member was allocated by the scan handler. That still works,
1272 but the GFS will ignore member display_term - assuming it was NOT set by
1273 the handler. The fact that the GFS now allocates the entries both allows
1274 for new members and makes a scan handler easier to write.
1276 Fix CQL lex buffer overflow.
1278 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1279 SRU default recordPacking is string.
1281 SRU protocol support for frontend server.
1283 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1285 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1287 Added scan for the ZOOM shell (zoomsh).
1291 * String Identifers for Schemas (Amendment 5).
1292 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1293 Old definition for schema
1294 Odr_oid *schema; /* OPT */
1299 Z_InternationalString *uri;
1300 #define Z_Schema_oid 1
1301 #define Z_Schema_uri 2
1304 * resultCount parameter to Sort Response (Amendment 1).
1305 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1307 Support for SRW 1.0 over HTTP. This is an optional feature and
1308 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1311 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1312 on the same port. SRW SearchRetrieveRequests are mapped
1313 to bend_init,bend_search,bend_fetch,bend_close.
1315 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1317 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1318 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1320 ZOOM connections are SRW based if schem http is used for hostname
1321 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1322 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1324 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1325 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1326 distance=n, order=true/false, relation=le, prox unit=word. If
1327 n is omitted, distance 1 is used.
1329 Fixed problem with C compiler include path in wrong order.
1331 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1332 on Solaris. Patch from Ko van der Sloot.
1334 New MARC decode API. All new functions operate on a yaz_marc_t
1335 handle. The most important new functions are: yaz_marc_create,
1336 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1337 decode and destroy respectively. Decoder can produce formats
1338 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1339 include/yaz/marcdisp.h.
1341 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1342 to UTF-8, UCS-32, wchar_t or Latin-1.
1344 * Prototypes for yaz_iconv_-functions moved to separate header
1345 include/yaz/yaz-iconv.h.
1347 Make a few private functions 'static' in unix.c. This prevents
1348 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1350 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1351 are set when Init Response is received.
1353 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1354 but returns diagnostic set as well.
1356 New function yaz_strerror which is a portable wrapper for
1357 strerror/strerror_r/GetLastMessage.
1359 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1360 is returned for MARC. If type is "oai", then OAI MARC is returned.
1362 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1365 --- 1.9.2 2002/11/26
1367 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1369 Fix bad race conditions on SIGTERM and terminate gracefully in
1372 Move retrieval (data1) module to Zebra since nobody seems to be
1375 Add GRS-1 render for ZOOM using same format as yaz-client.
1377 --- 1.9.1 2002/10/05
1379 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1381 Fix broken ESpec handling in data1 module.
1383 SGML reader parses comments and makes them part of the data1 tree.
1385 Added several type casts so that YAZ compiles as C++ code.
1387 ZOOM didn't handle PDU encoding failures properly.
1389 Added more Bib-1 diagnostics (approved extensions).
1391 GNU configure: better check for iconv.
1393 More portable use of accept, getpeername. Check for socklen_t. Use
1394 int/size_t if socklen_t is not defined.
1398 PQF parser rejects bad queries - including those with extra
1399 characters in them. PQF parser used to silently ignore that.
1400 Cleaner API for PQF added, which allows you to get detailed
1401 error information for bad queries (see yaz/pquery.h).
1403 Fixed bug in ZOOM_record_get for type "database".
1405 Implemented mini iconv library supporting conversions between
1406 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1408 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1410 --- 1.8.9 2002/08/20
1412 Fixed ZOOM C record cache so that preferredRecordSyntax and
1413 elementSetName is used to check for already fetched records.
1415 --- 1.8.8 2002/08/02
1417 Added three members in bend_initrequest structure to facilitate
1418 character set negotiation.
1420 Fixed a bug in frontend server that could cause indefinite
1421 loops under rare conditions.
1423 Revised character set utilities (charneg.h) so that encoding
1424 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1426 For PQF, directive @term <type> sets term type for Scan/Search.
1427 Here <type> is general, string, numeric, null. The term type
1428 is inherited - just like @attr.
1430 New call odr_set_charset that sets character set conversion for
1431 international-strings on a ODR stream. Prototype is:
1432 int odr_set_charset(ODR o, const char *to, const char *from);
1433 The InternationalString is still represented as C string in YAZ
1434 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1435 won't). On the protocol level, you can use any encoding.
1437 Support for UNIX sockets in ZOOM.
1439 Solaris recv sometimes returns errno == ENOENT. It is treated as
1440 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1442 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1443 both client and server. Code by Morten Bøgeskov.
1445 --- 1.8.7 2002/05/22
1447 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1448 that they can be used directly from Visual Basic. You must recompile
1449 your windows APP if you're using ZOOM.
1451 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1452 Commands "lang" and "charset" sets language and character set respectively.
1453 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1454 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1456 Attributes from multiple CCL fields may be OR'ed rather than merged
1457 using directive "@field or". Fields are still merged by default -
1458 equivalent to "@field merge".
1460 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1463 Fixed bug in zget for parameter ExtendedServicesResponse.
1467 --- 1.8.6 2002/03/25
1469 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1471 Client displays USR.1:SearchResult-1 (hits per term).
1473 Additional Search Info for search in Generic Frontend Server.
1475 Fixed CCL parsing of "field=s".
1477 WIN32 installer - using the excellent NSIS software from nullsoft.
1479 Fixed CCL parsing of "field = - <number>".
1481 Added function yaz_marc_decode that decodes MARC for line mode
1482 display or XML (similar to that used by JZKit).
1484 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1485 Z39.50. But ISO/ILL was, however.
1487 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1488 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1490 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1491 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1493 --- 1.8.5 2002/02/03
1495 New YAZ client features: Command completion and new commands:
1496 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1497 Code provided by Jacob Poulsen.
1499 New call oid_trav, that visits all registered OIDs via callback.
1501 Function ZOOM_record_get now returns const char pointer rather than
1502 void pointer. It saves a lot of type casts.
1504 For YAZ client, command "auth" now allows you to set authentication
1505 in IdPass style. It is enabled when three tokens are given - order
1506 is user, group and password.
1508 Fix memory leaks in MARC record handling for ZOOM.
1510 New option for YAZ client, -k <kilobytes> that sets
1511 maximum record size. Similar to -k option for generic frontend
1512 server and yaz-ztest.
1514 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1516 Prefix query parser reports "fail" when bad attribute set is given.
1518 Fix in MARC decoder. Proximity logging. Fix for attribute set
1519 in scan handler for server. Patches by Shigeru Ishida.
1521 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1524 Configure option --with-openssl=<dir> now works when a directory is
1525 specified. Patch provided by Morten Bøgeskov.
1527 New option for YAZ client, -u <auth>, that sets authentication.
1529 ZOOM fix: error information was sometimes "missing", since error
1530 was cleared/reset too when it shouldn't.
1532 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1534 --- 1.8.4 2002/01/04
1536 Scan for ZOOM API. New object ZOOM_scanset. New functions
1537 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1538 ZOOM_scanset_destroy.
1540 New ZOOM function, ZOOM_connection_last_event, that returns type
1541 of last event (such as "receive data", "send data", "apdu received",
1544 New ZOOM option, schema, that specifies schema for retrieval.
1546 New CCL feature. Qualifiers can be aliases for one or more
1547 other qualifiers (if more than one is given, OR is used).
1549 ZOOM uses named result sets if target supports it.
1551 Two new YAZ client commands: . (dot, which sources a script of YAZ
1552 client commands), and ! (to execute shell command.). Implemented
1555 Working on Debian packages.
1557 --- 1.8.3 2001/11/19
1559 YAZ client enables named result sets only if target supports it.
1561 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1563 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1564 with key="host" to get same result.
1566 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1567 Function Z3950_resultset_record(s) returns references to records
1568 "owned" by resultset. To become owner use Z3950_record_clone.
1570 Function z_ext_record handles Extended Services. Thanks to
1573 --- 1.8.2 2001/11/12
1575 CCL Parser fix: ignore token comma when dealing with and-lists.
1577 Documentation updates for COMSTACK.
1579 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1580 Changed prototype Z3950_records. For some functions, int parameters
1581 were changed to size_t.
1583 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1586 New MARC decode/display function, marc_display_exl, which properly rejects
1587 non-ISO2709 records. YAZ client uses it.
1589 --- 1.8.1 2001/10/29
1591 Fix bug: local attribute set wasn't set correctly in PQF strings.
1595 * Old Z39.50 codecs no longer supported.
1597 Added ZOOM C binding. See http://zoom.z3950.org/
1599 Renamed states for COMSTACKs to avoid confusion with events.
1601 Implemented cs_look and proper cs_rcvconnect.
1603 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1605 Configure detects POSIX threads on OpenBSD.
1607 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1608 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1610 When error is returned from present handler, non-surrogate diagnostic
1611 is returned in present response (and fetch handler is no longer called).
1613 * Minor adjustments to pquery parser (PQF). Token characters may be
1614 escaped by using backslash (C-style).
1616 PQF parser allows string attribute values to be specified. For @attr,
1617 non-numeric characters after the equal-sign are treated as strings
1618 (e.g. @attr 9=title).
1620 CCL trunction character may be defined (@truncation in file)
1622 * function zget_ExtendedServicesRequest sets waitAction to
1623 waitIfPossible (was wait).
1625 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1628 CCL operator names may be set in field definition files (CCL_bibset).
1629 See ccl/bib1 for an example.
1631 Fixes in ASN.1 compiler for C++ compatibility.
1633 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1634 and "op_or" to avoid conflict with C++.
1636 Fixed problem with GNU readline detection on Redhat 7.0.
1638 Added step-size for Scan backend handler.
1640 Fixed bug that made the frontend server crash when no attribute
1641 set was specified for scan.
1643 Front-end server automatically switches to original working directory
1644 when installed as an NT service. Previously -w had to be specified to
1647 Added extended attributes for retrieval module (data1), so that data1
1648 records carry d1_readXML/SGML attributes. d1_read also supports
1649 null-data rules ( <tag/>)
1651 On UNIX when POSIX threads are available, a separate library libyazthread
1652 is created. Programmers should link with that library and the yaz library
1653 when using threads. The reason for the split was that some applications
1654 on Linux, such as Apache, doesn't work well when using shared objects that
1657 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1658 (or any frontend server) in SSL mode by specifying ssl: followed by
1659 address. Only tested on UNIX.
1661 Added feature for CCL module. Virtual structure s=al or s=ol generates
1662 and-list and or-list respectively instead of phrase search.
1666 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1667 log_mask_str. This was done to avoid name conflicts with other libraries
1668 (such as other PHP extensions).
1670 Added raw OID member for preferred record syntax (request_format_raw)
1671 and returned record syntax (output_format_raw) for backend fetch method.
1673 Config file yaz-config now accepts options so that it returns specific
1674 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1676 Shared library support for UNIX using GNU libtool.
1678 * Modified backend interface. Request/Response struct's replaced by
1679 one read/write C struct. For example bend_fetchrequest and
1680 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1681 Every handler - even search has to be registered in bend_init
1682 handler. This means that the YAZ library no longer refers to
1683 external functions and it makes it possible to make the whole
1684 thing a single DLL/SO.
1686 Added Segment handler for backend server.
1688 Added Zmbol/Zebra administrative functions to YAZ client.
1690 Threaded frontend server on UNIX (when POSIX Threads are available).
1691 Starting the server with option -T enables multi-threading.
1695 Added configure option --enable-comp/disable-comp to control use
1696 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1697 located in sub directory asn.
1699 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1700 in ${exec_prefix}/bin along with the other programs yaz-client and
1703 GNU automake used to maintain makefiles.
1705 Added several OID's.
1707 Changed retrieval module so that we can load records with no abstract
1708 syntax defined. Tagpaths in these records are fully composed of string
1711 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1715 On UNIX, the generated makefile now supports a proper 'make install'.
1716 The prefix can be set via GNU configure to set the install location
1717 (default is /usr/local).
1719 * YAZ programs client and ztest were renamed to yaz-client and
1720 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1721 locations, such as /usr/bin,/usr/local/bin,etc.
1723 * YAZ Header files were moved from include to include/yaz. YAZ Header
1724 files are referred to as include <yaz/log.h> rather than <log.h>.
1725 The YAZ include path (-I ..) is therefore the same as before. Programmers
1726 should update their #include statements or use -Ipath/include/yaz
1727 instead. The main motivation for doing this change is that YAZ header files
1728 can be installed in "standard" locations /usr/include,/usr/local/include
1729 without introducing conflicts, since ALL YAZ header files are stored
1730 in subdirectory yaz (under /usr/include for example).
1732 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1733 rather than project/workspace files. We switched because project files
1734 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1737 Changed name of logging function, logf, to yaz_log, to prevent name
1738 clash with some math-log functions. The YAZ header log.h defines logf
1739 to yaz_log (#define) so there should be no incompatibilities by this
1742 Added bend_start/bend_stop handlers for server. These handler are
1743 called on start/stop of server. For windows they are called whenever
1744 a service is started/stopped.
1746 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1747 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1748 in util/yc.tcl. The auto-generated C code structures are, in a few
1749 cases, incompatible with the old decoders. There are differences in the
1750 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1751 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1752 The preprocessor variable ASN_COMPILED is defined when the compiled
1753 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1754 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1755 wish to use the old encoders/decoders you can specify --disable-yc
1758 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1759 version so that it supports both new - and old version of DB Update
1761 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1762 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1763 change. The name parameter can be set to 0 in which no name is specified
1764 for the construction. The macros odr_implicit and odr_explicit sets name
1765 parameter to zero for the construction involved. New macros
1766 odr_implicit_tag and odr_explicit_tag are similar to the others,
1767 except that a name parameter is added. For programmers' that don't use
1768 ODR they probably only need to change the call to z_APDU and z_External.
1770 Added access control facility by interfacing the TCP wrapper library.
1771 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1772 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1773 name of the daemon and enables the access control as specified in
1774 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1776 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1777 den Dool <H.M.vdnDool@kub.nl>.
1779 Added reference ID parameter to most functions in server API - refer
1780 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1782 Changed name of ccl library to libccl.a (was ccl.a).
1784 Fixed bug in decoder for Explain (Category TargetInfo).
1786 Added support for GNU readline in client. Thanks to Jacob Poulsen
1787 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1789 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1790 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1791 IMPLEMENTATION! This change was made to the development version before
1792 the ZIG decided to retract the amendment. If any users MUST be
1793 compatible with the original Update definition, PLEASE CONTACT US, and
1794 we will include a separate definition corresponding to the old Update
1795 ES. Note that because of the change to the ASN.1 of the
1796 TaskPackageRecordStructure we cannot define a single structure that
1797 will support both versions.
1799 * Added const modifier to buffer parameter for some ODR/BER encoding
1800 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1801 completeWAIS, odr_dumpBER.
1803 Fixed bug in client.c which caused a crash when a scanResponse didn't
1804 contain positionOfTerm.
1806 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1807 * will cause an error in a client if a non-YAZ target sends both a
1808 * list of Scan entries and non-surrogate diagnostics.
1810 Retrieval module enhancements. Tag sets may be typed in the reference
1811 to it. From the .abs-file the "tagset" directive takes a third optional
1812 integer type for the tag set referenced. From a .tag-file the "include"
1813 directive takes a third optional type as well. The old "type" directive
1814 in the tag set itself is still recognized but acts as the default type
1817 Backend interface change. Individual Scan terms returned from bend_scan
1818 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1819 in include/backend.h.
1821 Retrieval module enhancements. Multiple tag sets and attribute sets may
1822 be specified in abstract syntax specs. Revised the error/warning for
1823 logging messages reported by the retrieval module when reading the
1826 Object Identifier system (oid_..) changed. The API is backwards
1827 compatible but the oid-routines now allocates new OID's when needed.
1828 Raw OID's may be specified in oid_getvalbyname.
1830 YAZ now uses GNU configure to generate Makefile(s).
1832 * Minor changes in some of the member names of DeleteResultSetRequest and
1833 DeleteResultSetResponse. See include/proto.h.
1835 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1836 and added member 'languages' in TargetInfo (which was missing).
1838 Changed the way attribute sets are handled in the retrieval
1839 module. These are now cached, just like the abstract syntaxes
1842 Changed YAZ so that it links with compiled ASN.1.
1844 Added Explain-schema definitions and mapping routines. The following
1845 Explain categories have been implemented: AttributeDetails,
1846 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1848 Fixed minor bug in Windows version of Server Library.
1850 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1852 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1854 Added EXTERNAL: UNIverse Resource Report (non-standard).
1856 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1857 ENUMERATED and SET OF.
1859 * Added 'const' to some of the char pointer arguments for the
1860 functions, data1_read_node, data1_getelementbytagname,
1861 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1864 Fixed bug in data1_insert_taggeddata - the last_child member of
1865 parent wasn't initialised.
1867 * Changed data1_read_record and data1_read_node so that the supplied
1868 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1869 doesn't refer to any parts of the "SGML"-buffer.
1871 Fixed bug in server library (Windows version of statserv_remove).
1873 * Changed code so that it compiles as C++. The type definition
1874 of Odr_fun which is a member of Odr_arm was changed. The result is,
1875 that an explicit typecast is needed for the fun pointer when
1876 using Odr_arm - as in:
1877 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1879 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1881 Implemented the new structured date and time definition as approved
1882 by the ZIG. Added schemaId element to the specificTag in Espec-1
1883 (also approved at the last ZIG). Thanks to RVDM.
1885 Added some Object identifiers (RVDM).
1887 Changed the Update Extended Service (RVDM).
1889 Added command "refid" to client which specifies referenceId for
1890 the following requests.
1892 Implemented extended service handling for server. See ztest.c
1893 for an example as well as backend.h. New handlers are registerd
1894 in the Init handler.
1896 * Changed interface for sort in server.
1898 Added new members to statserv_options_block. It allows a server
1899 to read options from another source than just the command line. Thanks
1900 to Charles Woodfield.
1902 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1903 renamed to zboolean. Some C++ compilers complained about the name.
1905 Minor changes to gils.abs. Added index 's' (sort) on title
1906 and date/time-last-modified.
1908 --- 1.4pl2 1998/1/30
1910 Fixed bug in server library regarding inetd mode (-i). This bug
1911 was introduced by release 1.4.
1913 --- 1.4pl1 1998/1/29
1915 Added sort facility in client and backend server interface.
1917 Fixed problem with dependencies in Makefile(s).
1919 Fixed bugs for encoders/decoders of extended services and
1922 Implemented sub-tree feature for schemas. Sub-trees are
1923 referenced in *.abs-files. See explain.abs for an example
1924 of the use of this feature.
1926 Modified bib1.att; local attributes for ANY didn't include
1927 ANY itself (only affects use of the retrieval module).
1929 Fixed bug in plain SGML reader in function data1_read_node:
1930 tags with prefix "var" was incorrectly interpreted as variants.
1932 Added feature "sub-schemas" to enable references to - and definitions
1933 of - group of elements.
1935 * Removed member parent from type data1_element (in data1.h).
1937 Implemented function odr_nullval() that returns the value of
1940 * Removed member num_children from data1_node (in data1.h).
1942 Made NT service interface part of the server library. The
1943 function statserv_main uses the NT service when required and
1944 calls the statserv_start / statserv_close routines.
1946 Routine zget_SearchRequest and zget_PresentRequest fills
1947 resultSetName/Id member with "default" instead of "Default".
1949 Fixed memory leak in server. Request queue member wasn't freed.
1951 Fixed nmem_exit so that memory is freed.
1955 Revised the CCL parser utility to be thread safe.
1957 Added function, oid_ent_to_oid, to replace the function
1958 oid_getoidbyent, which is not thread safe.
1960 * Added nmem_init and nmem_exit to initialize and release
1961 NMEM resources. Function nmem_init should be called once in the
1962 initial thread before NMEM/ODR is used. statserv.c and client.c
1963 have been changed accordingly. The change was necessary to make
1964 NMEM thread safe. The NMEM memory pool is shared amongst threads
1965 in a process. Unix-based applications will still work fine without
1968 Added NT Services interface for the the Z39.50 (statserv) Server.
1969 Refer to the ztest.c source on the usage.
1971 Windows 95/NT port using MSVC5.0. Project files are included in the
1974 * Defined new 'global' handle for the retrieval (data1) system. The
1975 new handled, data1_handle, describes the state of the data1 system.
1976 This handle is passed as first argument to virtually all
1977 data1 related routines. The functions data1_create and data1_destroy
1978 creates and destroys a data1 handle respectively.
1980 Added ODR encode stream member to all backend request structures
1981 init, search, scan etc. This stream should be used to allocate all
1982 memory used for the response when thread safe operation is needed.
1984 Changed the comstack utility, cs_addstr, to be thread safe. The
1985 returned hostname string returned by the function is now part the
1988 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1989 function. The cs_straddr takes a COMSTACK handle as argument, so this
1990 function must be used after cs_create and before bind/connect.
1991 This function is thread safe.
1993 Moved test server to 'ztest' directory - generic server code still
1994 in 'server' directory.
1996 Made prefix query (pquery.c) utility thread safe.
1998 Added new function modifier YAZ_EXPORT to 'export' public DLL
1999 functions when using windows (see include/yconfig.h).
2001 Added definitions to the OID database (util/oid.c) (RVDM).
2003 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2005 Added call to ccl_rpn_delete in client program.
2007 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2008 release of RPN structure.
2010 Added support for C++, headers uses extern "C" for public definitions.
2011 With input from RVDM.
2013 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2014 Thanks to Ronald van der Meer (RVDM).
2016 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2018 Added support for private extensions to the OID database
2019 (oid_setprivateoids()). Thanks to RVDM.
2021 Added optional, physical ANY (key replication)
2023 Fixed null-reference problem in GRS-1 output filter.
2025 Proximity operator added to Prefix Query Format (PQF).
2027 In test client command "base" accepts multiple databases.
2029 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2033 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2035 Smallish bug-fixes in the new encoders/decoders (explain).
2037 Bug fixed in DeleteRequest.
2039 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2041 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2043 Added SOIF syntax (using private OID for now) to retrieval module and client.
2045 Added Update extended service.
2047 Added SearchResult-1 additional info structure.
2049 Added optional CCL (ISO8777) interpreter as separate module. Available
2052 --- 1.2 1996/6/10 (1st anniversary release)
2054 Added Summary record syntax. Lightly tested.
2056 Added OPAC record syntax. Untested.
2058 Added ResourceReport service encoders/decoders. Untested.
2060 Fixed bug in z_Unit - wrong tagging on unitSystem.
2062 Fixed bug in the DiagRecs decoder.
2064 Added options for max PDU size and session timeout to frontend-server.
2066 Added documentation of query-language parsers and other supporting utilities.
2068 [frontend-server] Added Attribute set to the bend_scanrequest API.
2070 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2071 surrogate diagnostics were generated.
2073 [retrieval] Allow multiple local values for attribute.
2075 [retrieval] Allow multiple attributes per element in .abs files. index type.
2077 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2079 --- 1.1pl2 1996/4/10
2081 Minor changes, mostly specific to Zebra's requirements (retrieval)
2085 Repaired bug in frontend server when running multiple listening
2086 endpoints in dynamic mode.
2088 z_External() now won't break if a known, ASN.1 value comes encapsulated
2089 in an octet-string. The value will pass through unmodified in an Odr_oct.
2091 Added a bit of code to the demo client to decode & display
2092 ASN.1-structured records represented in the octet-aligned branch of
2093 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2095 Added z_ext_getentbyref() to the ASN module. Doc updated.
2097 * Completed the SCAN definition in the ASN module. This may break SCAN
2098 code based on older YAZ-versions at compile-time. The fix is easy -
2101 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2102 under the SCAN definition. Remember to initialize this, server-people.
2104 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2105 that this does not extend to ODR and ASN.
2107 Comstack allows insertion of established socket (primarily for
2108 inetd-operation of servers). Doc updated.
2110 Front-end server can now start from the inetd in TCP mode. Doc
2113 --- 1.0pl4 1996/1/24
2117 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2118 the rank and record number.
2120 Adjustments to the frontend server.
2122 Fixed diagnostic BER dumper. It ignored the file argument.
2126 Various changes to retrieval module.
2128 Changed the union discriminators of the protocol files from enums to
2129 ints paired with #defines.
2131 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2134 *Changed operator in the RPN structure to 'roperator', again to avoid a
2137 Fixed problems in Explain decoders/encoders.
2139 --- 1.0pl2 1995/12/6
2141 Memory bug in log module fixed.
2143 --- 1.0pl1 1995/12/5
2145 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2147 Bug in Explain DatabaseInfo module fixed.
2149 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2153 The shift to v1.0 signals that we now consider the *core* functionality
2154 of YAZ reasonably stable (the core being more or less equivalent to
2155 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2156 tested (Explain not at all - though that will happen soonish).
2158 Minor changes to code to support Windows port.
2160 Various minor changes after we're getting to use GRS-1 & co. more.
2162 Added Espec-1 format.
2164 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2165 of the protocol and it cannot be selected when encoding (maps into 'string'
2166 when decoding). Needed to talk to some servers.
2168 Demo client can request simple element set names.
2170 Added Diagnostic Format encoders/decoders.
2172 Added simple Close handling to frontend server (no hooks for resource
2173 reporting yet), and demonstration client.
2175 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2177 --- 1.0b3 1995/08/24
2179 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2180 handled incorrectly when records were requested in the searchResponse. This
2181 will only affect you if you use the frontend-server.
2183 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2184 Test-client will ask for and print GRS1. Ztest will return dummy records
2187 Added Explain encoders/decoders to the service-level API. Untested.
2189 Added Extended Services: Item Order encoders and decoders to the Service-
2190 level API. Untested. We could use a recent copy of the pertinent bits
2191 of the ILL protocol to add those bits.
2193 Added diagnostic format 1 encoders/decoders to the service-level API.
2196 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2197 odr_cons.c, which causes a more correct output.
2199 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2200 was always set to 0 when no records were requested in the searchRequest.
2202 * Added better external-handling. This shouldn't harm old code that
2203 *encodes* externals. It can break code that looks for a
2204 'single-ASN1-type' representation, since those types that are known
2205 are now decoded immediately. Look at the SUTRS sample code in
2206 seshigh.c and client.c. Documentation updated.
2208 Handling of structured records in bend_fetchresponse. Length -1 marks
2209 structured record, type is deduced from format field.
2211 --- 1.0b2 1995/06/27
2212 Fairly quick maintenance release to add SUTRS support.
2214 Fixed handling of SUTRS records in the demonstration client.
2216 * Added format field to the bend_fetchrequest and bend_fetchresponce
2217 structures of the backend API (frontend server). When the record is
2218 returned, the value of the format field is mapped to an OID. The
2219 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2220 of the record. The special value VAL_NONE in the bend_request means
2221 that no specific format was requested by the client. Documentation
2222 updated accordingly. Test server (ztest) will return a fixed dummy
2223 SUTRS record if your client requests SUTRS.
2225 Documentation updated accordingly.
2227 You can now set external libraries and RANLIB support in the top-level
2231 First public release.
