1 Added support for the use of the older versions or Extended Service
2 Update in ZOOM. To faciliate this, an option "updateVersion" may be
3 set to the version , 1=first, 2=second, 3=third. The third version is
4 what ZOOM C has used so far. And that, obviously, is the default.
8 Fixed bug #1208: SSL appears to be broken in ZOOM.
10 Fixed bug #1206: Libxml2 include path weirdness.
12 Added oid_name_to_dotstring.
14 Allow elementSetName to be specified for ZOOM C record update.
16 Allow waitAction to be specified for ZOOM C based for Extended Services.
18 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
19 syntax OID. Bug introduced in YAZ 3 series.
21 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
25 Fixed bug #1157: yaz-client does not read .yazclientrc from current
26 directory. yaz-client now reads commands from file given by option -f
27 if specified; then tries to read .yazclientrc in current directory.
28 Failing that, it reads .yazclientrc from user's home directory.
30 Added support for correlationInfo Note and ID for Record Update via
33 Added yaz-client command querycharset which specifies character set for
34 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
35 (termListAndStartPoint).
37 Charset ISO5428:1984 is an alias for ISO5428-1984.
39 Implemented a way to perform scan in a result set using Z39.50. This
40 is achieved by attaching the result set name in the characterInfo
41 (type InternationalString) of OtherInformation in the Scan Request PDU.
42 The result set is identified in the otherinformation by the new OID:
43 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
44 This allows for scan in result set and faceted search . Zebra did some
45 of this in the APT term using attribute type 8 and value being result
46 set. Using the OtherInformation approach for this is cleaner and easier
47 to work with in proxies and the like. This facility can be used in
48 yaz-client using new command setscan which takes a result set as first
49 argument, start position (APT) as second.
51 Changed decoding of SRU XML packed records to deal with servers that
52 have recordData with XML data with multiple root nodes. Also make
53 comparison for recordPacking case insensitive. Again, one server
54 returns "XML" where others return "xml".
56 For SRU responses allow Content-Type application/xml as well as text/xml.
60 Fixed bug in character set conversion of BER strings. Bug introduced
65 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
67 For OID class, use oid_class consistently.
69 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
72 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
73 character set for bibliographic information interchange". By Giannis Kosmas.
75 Added documentation on new OID API.
79 Changes to generic frontend server interface: added new member
80 'query_charset' for bend_initrequest structure. A backend init handler
81 should set this member to its native character set for query terms.
82 When defined, the frontend server logic will announce this character set
83 to a client if the negotiationModel bit is set by the client. All server
84 implementors are encouraged to specify this. If a backend server does not
85 specify this a warning is issued using yaz_log(YLOG_WARN,..).
87 Added CCL utility to remove terms (stop words) from resulting RPN
88 tree. This is handled by functions with prefix ccl_stop_words_ .
90 New ZOOM C option, "rpnCharset", which allows client-side conversion of
93 Clean-up the CCL API. Moved some internal structures from ccl.h to
94 private header cclp.h. Changed ccl_parser_create so that a Bibset must
95 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
96 This is replaced by ccl_parser_find_str which takes a string instead.
98 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
99 libyaz.la is the core of YAZ except the generic frontend server and
100 does not depend on POSIX threads anymore. libyaz_server.la is the
101 generic frontend server facilities and uses POSIX thread functionality
102 if available. The libyaz.la no longer depends on POSIX threads because
103 the number of global structures is limited. NMEM no longer re-uses blocks
104 between threads ; it simply free's memory immediately but allocates in
105 "large" chunks as usual. We don't expect any performance penalties
106 because of this. The yaz_log system is still using a global log_level so
107 caution must be taken when modifying it with yaz_log_init_.. +
108 yaz_log_mask_str. This, however, should not cause any trouble because
109 these functions are called during initialization of application code
110 anyway. `yaz-config --libs server` returns libs for server applications;
111 `yaz-config --libs` returns libs for non-server applications.
113 New OID database - with public definitions in oid_db.h. Removed old OID
114 database including the head oid.h and definitions such as enum oid_value
115 and struct oident. The new OID database uses the same string names as
116 before but the 'protocol' is gone. There are now only two representations
117 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
118 converts from string to OID; functions with prefix yaz_oid_to_string
119 converts the other way.
121 Change to emit_term() in CQL-to-PQF query translation: when a term has
122 the /regexp relation modifier, do not process it for leading and
123 trailing "^" and "*", which have quite different meanings in regular
126 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
127 write handlers no longer carries a 'last' parameter. This will make
128 yaz_iconv flush "less" characters. A flush is performed by call to
129 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
131 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
132 removed, because function yaz_query_to_wrbuf does the same.
134 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
135 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
137 Deprecated MARC utility functions removed.
139 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
142 Branch split: YAZ_2_1_55_branch
144 --- 2.1.54 2007/03/16
146 Fix to ZOOM-C so that transparent reconnection is properly handled on
147 connections that are in asynchronous mode.
149 Fixed compilation on OpenBSD 4.0.
151 Large strings in GRS-1 records are now properly displayed in yaz-client.
153 Added character conversion support for "advancegreek"; based on patch from
156 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
157 sequence is met. Before the error was not set so it would be unknown.
159 Adjust yaz-marcdump MARC reader so that it skips until record separator
162 --- 2.1.52 2007/03/07
164 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
165 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
166 fd_set structure used as a bitmask for the FDs to be selected on.
168 Using ACX_PTHREAD macro to check for POSIX threads.
170 Fixed have-vsnprintf check.
172 --- 2.1.50 2007/02/23
174 Fixes for configure on BSD. Bug #900.
176 Added snprintf/vsnprintf wrappers for systems that don't have
177 limits (heavens forbid).
179 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
180 created before all previous tasks were completed and removed from the
181 task queue, the new task could be removed by a mistake.
183 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
185 Implemented pass-through CQL-to-PQF conversions. Bug #861.
187 Fixed bug #832: Problem with MARC/charset in yaz-client.
189 Fixed bug #668: save command line history for yaz-client.
191 Fixed bug #830: pkg-config support.
193 --- 2.1.48 2007/01/23
195 Extended ZOOM result set options with two options that may be read by
196 a client: resultSetStatus and presentStatus with values as specified for
198 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
200 Fixed bug #827: Using SSL fails on Debian etch.
202 Fixed bug #826: Weird looking chars for set of MARC records.
204 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
205 that is treated as an ItemOrder with itemRequest being an XML document
206 external. The value of "doc" is the content.
208 Extended the GFS search facility. New member of bend_search_rr
209 'estimated_hit_count' signals that hits is known to be an estmate
210 (higher or lower than real hit count). New member 'partial_resultset'
211 signals that the search was partial (hit count is lower or equal than
212 real hit count). For Z39.50, the information is stored in resultSetStatus
213 member of SearchResponse APDU. For SRU, the information is signalled
214 via SRU diagnostic 59: "Result set created with valid partial results
217 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
219 --- 2.1.46 2007/01/13
221 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
223 Added ZOOM_connection_peek_event.
225 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
226 the following new functions:
227 ZOOM_event_nonblock, ZOOM_connection_process,
228 ZOOM_connection_get_{socket,mask,timeout},
229 ZOOM_connection_fire_event_{timeout,socket}.
230 The existing blocking event handler, ZOOM_event, is a wrapper for the
231 + blocking ZOOM_event_sys_{poll,select}.
233 Implemented function ccl_xml_config which parses XML version of CCL
234 configuration (bug #798).
236 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
238 Added timings utility (yaz/timing.h)
240 --- 2.1.44 2007/01/03
242 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
245 Fixed bug #779: Rotation of apdu.log fails.
247 Fixed for character set conversions:
248 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
249 Honor G1 set in MARC-8 decoding.
251 --- 2.1.42 2006/12/17
253 Fixed bug #775: char conversion does not handle Alternative UTF-8
256 Implemented function yaz_marc_read_line which parses MARC line format
257 records. There is a wealth of formats out there. So far, this function
258 reads line records produced by yaz_marc_write_line.
260 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
261 more generic and easier to remember(!) options: -i format and -o format
262 which specifies input format and output format respectively - where
263 format is one of "marc", "marcxml", "line", "marcxchange".
265 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
266 does not print anything except warnings for records.
268 For yaz-marcdump, added support for MARC split into files (-s) with a given
271 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
272 spec, at http://www.loc.gov/standards/sru/record-update/
273 This has changed the binary layout of the following structs:
274 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
275 bend_update_rr . Patch by Ko van der Sloot.
277 Added GFS utility function bend_assoc_is_alive which returns 1 if
278 association is still alive (client is connected); 0 otherwise (client
279 closed connection). This allows busy servers to stop working for
282 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
283 been a separate piece of software. This version of ziffy has been modified
284 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
286 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
288 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
289 Client code may now interrogate options such as "init_opt_sort" to
290 find out whether the server claims to support various options.
292 --- 2.1.40 2006/11/27
294 Added utilities yaz_{set,get}_esn to set/get element set name from
297 Removed the build of libyazthread.la. The libyaz.so is the threaded version
298 of YAZ and has been so since YAZ 2.1.10.
300 Implemented ZOOM_record_error which returns error information for
301 record (surrogate diagnostic).
303 --- 2.1.38 2006/10/31
305 Updates for SRU Update by Ko van der Sloot:
306 1. Changed name from "operation" to "action"
307 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
308 versions in the code, marked as 'backward compatible'.
309 3. Added diagnostics for SRU Update.
311 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
313 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
315 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
317 For GFS, fixed problem with SRU diagnostic 'First record position out of
318 range' being issued for 0 hits.
320 zoomtst10 part of Windows Build.
322 --- 2.1.36 2006/10/13
324 Implemented yaz_filepath_comp which splits a path into file path
325 components (required by Zebra 2.0.3+).
327 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
328 BSD inspired license until now so this should not have any real impact on
329 anybody. See http://www.opensource.org/licenses/bsd-license.php
331 Fixed bug #687: Missing log lines.
333 Fixed bug #678: CQL to PQF translation does not preserve double-quote
336 Fixed bug #689: SRU diagnostics to be added.
338 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
339 whether a connection is idle (no more work do do).
341 --- 2.1.34 2006/10/04
343 Change type of optval from long to int for invocation of setsockopt with
344 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
346 Added support for specifying the max log file size for the Generic
347 Frontend Server. The size is given with option -r.
349 --- 2.1.32 2006/09/21
351 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
353 --- 2.1.30 2006/09/17
355 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
358 Fixed bug in Generic Frontend Server that could cause a server to stop
359 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
361 For the generic frontend server, the maximum record size is used as maximum
362 size of incoming packages (SRU + Z39.50). The value until was previously
363 only used in Z39.50 Init negotiation and, later, in a session controlled
364 sizes of records returned. This is controlled using -k option. It can be
365 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
367 --- 2.1.28 2006/09/04
369 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
372 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
374 New option for yaz-marcdump -lpos=value which allows setting a portion
375 of MARC header to a certain value.
377 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
379 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
380 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
382 --- 2.1.26 2006/08/15
384 Fixed problem with SRU mode type (soap, get, post) for yaz-client
387 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
389 --- 2.1.24 2006/08/08
391 Fixed MARC ISO2709 encoding routines to deal with character set
394 Minor changes to GFS logging. Database included in search request log
397 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
398 cached/multiple records.
400 Shared libraries are built by default on Unix+configure.
402 Changed cql2pqf transformation to use a different evaluation order. The
403 new order is: always, relation, structure, position, truncation, index
404 and relationModifier. Old order was: always, relation, relationModifier,
405 structure, index, position, truncation. Note that the the latter ones
406 override former ones for identical attributes.. The new scheme means that
407 it is possible to override any existing attribute with a relationModifier.
408 And also that it is possible to override everything for the index rule
409 (except the ones listed in relationModifier). No order is perfect but this
410 one, we believe, covers more real cases.. The "always" should have been
411 called "default", since the attributes there can be overridden with all
414 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
415 compilation phase, but also for yaz-config --cflags output. This allows
416 us to have public headers with Libxml2 stuff in them . It should also,
417 eventually, make Libxml2 checks redundant in packages using YAZ, such
420 --- 2.1.22 2006/06/15
422 Changed SRU update structure bend_update_rr so that SRU diagnostics are
423 stored in uri, message and details.. Previously diagnostics were stored
424 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
425 compatibility.. but he's probably the only one affected, so.
427 Added support for CCL, compiled on the client side, in ZOOM-C. This
428 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
429 input; the resulting query objects can be used for for searching with
430 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
432 YAZ' configure searches for OpenSSL by default.
434 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
435 SL_CTX_use_certificate_file. See
436 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
437 for more info. Thanks to Ko van der Sloot.
439 --- 2.1.20 2006/06/02
441 Bug #600: SRU GET, POST support for yaz-client. Introduced
442 command 'sru' which selects method SOAP/GET/POST.
444 Allow missingValueAction to be specified for the sortspec string -
445 function yaz_sort_spec. By default, the missing value action is null.
446 Use ! to specify "abort". Use = followed by stringvalue to specify default
449 Ensured that Present-handler (if defined) is called in GFS before any call to
450 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
451 searchRetrieve requests.
453 Documentation for YAZ is now based on the Docbook XML/XSLT using
454 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
455 is no longer depending on jade/openjade or docbook-to-man scripts.
456 PDF is no longer part of the distribution - but can optionally be
457 made using DSSSL/jadetex or FOP.
459 Added retrieval handling support in Generic Frontend Server to support
460 conversion between MARC/XML as well as XSLTtransforms. See
461 etc/yazgfs.xml for an example.
463 Added Authentication support to Generic Frontend Server in SRU
464 mode. Authentication using HTTP Basic is supported, as is the use
465 of 'x-username' and 'x-password' parameters in the request itself.
467 Added support for a new character set MARC8s identical to MARC8 except
468 that it converts combined characters to single Unicode characters in the
469 Latin-1 range (when possible).
471 --- 2.1.18 2006/04/24
473 ASN.1 compiler 0.4: generates brief Doxygen file header for
474 generated .h/.c files.
476 Utility yaz_iconv now supports conversion to MARC-8.
478 New facilities for the MARC module. The reading - and writing of
479 content are separate methods for the yaz_marc_t handle. The following
480 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
481 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
482 format). Write functions have prefix yaz_marc_write_.. The existing
483 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
484 available. Removed support for OAI-MARC and simplexml (not the
485 simplexml from PHP5).
487 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
488 to be returned for this connection.
490 --- 2.1.16 2006/03/31
492 Allow multiple languages and charsets to be specified with
493 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
494 negcharset iso-8859-1,utf-8
496 Translation of proximity nodes from CQL into PQF now works.
498 Moved to automake 1.8, 1.9.
500 Added function yaz_log_set_handler which allows a log handler to be
501 installed. This handler will be called for all log messages. Output
502 to file is also produced; but that can be disabled by passing NULL
503 fname to yaz_log_init_file.
505 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
507 For SRW (including GFS), accept application/soap+xml as content-type
510 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
511 produces NO stylesheet reference even if a default stylesheet is specified
514 --- 2.1.14 2006/03/14
516 Updated Windows package to include yazd.dll + yazd.lib for the
517 Development component.
519 If the environment variable YAZ_LOG is set, then it is used as a
520 string indicating the default level of logging to use if not
521 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
522 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
523 used as before. So, for example, to omit warnings from YAZ logging,
526 cql_transform() now map structure and other attributes before indexes,
527 so that index-specific structures and other attributes can override
528 defaults. So now a combination of mapping specifications such as:
530 index.dc.date = 1=date-modified 4=5
531 does the right thing.
533 cql_transform() now also respects the "always" mapping specification,
534 which establishes an initial set of attributes to be used for all
535 terms except where overridden by more specific attributes associated
536 with the index, relation or modifier.
538 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
539 which mode to use; one of "post", "get" or "soap" (SRW, default).
541 Fixes for yaz_iconv routines: changed trie-based character set conversions
542 to use only non-negative values for bit fields due to Sun's C compiler not
543 supporting negative values.
545 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
546 sequences where not read correctly. Fix by Rustam Usmanov.
548 Updated win/makefile to use options, settings which makes things
549 compile with VS C 2005.
551 --- 2.1.12 2006/02/01
553 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
555 In ZOOM socket code, use select instead of poll on MacOSX.
557 ZOOM-C now support client-side compilation of CQL into RPN that is
558 sent to the server, enabling CQL to be used against all Z39.50
559 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
560 ZOOM_query object, and submit it using ZOOM_connection_search().
561 The CQL-to-RPN translation uses a configuration file, the name of
562 which must be specified in the Connection's "cqlfile" option.
564 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
565 function, which takes as its start-term parameter a ZOOM_query object
566 (which may have had either CQL or RPN set into it).
569 --- 2.1.10 2005/11/29
571 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
572 GFS to support this as well. Backend handler, bend_srw_update, does the
573 update work. Code contributed by Ko van der Sloot.
575 Allow retrieval of Search Result-1 information in ZOOM by the use of
576 options that are attached to a result set. ZOOM documentation updated
579 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
580 UTF-8 conversion. Patch by Raj Patel.
582 Added option -m to GFS to control formatting of timestamps in log file.
584 Added 'exit' as synonym for 'quit' in yaz-client
586 Added support for specifying SRW resultSetId + resultSetIdleTime in a
587 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
588 for the new members. Patch by Ko van der Sloot.
590 Added support for SRU POST. It is supported for content-type
591 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
593 Do not build the separate Multi-threaded (MT) library libyazthread.la.
594 Instead make the library libyaz.la multi-threaded. Threading as a whole
595 can still be disabled by configure option --disable-threads. Previosly,
596 with older GLIBCs there were problems with MT libs under Apache. This
597 has now been fixed a long time ago.
599 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
602 CQL module modified to be case insensitive for relations/indexes/operations.
604 Fixed bug in CQL transform code: incorrect value relationModifieder
607 Added 'show all' command for yaz-client which retrieves all results
610 Added new yaz-client, xmles, which takes a (private) OID and
611 a document to be sent as an extended service request.
613 Describe new yaz-client commands wait_response and set_auto_wait.
615 Increase TCP/IP listener backlog from 3 (which I am guessing was
616 copied from the SunOS manual entry way back when) so SOMAXCONN, so
617 that the socket will queue as many incoming connections as it's able
618 to handle ongoing connections. In other words, it will never now
619 refuse a connection that it would be able to handle merely because
620 it's not got around to accepting() enough of the pending connections
621 yet. This is the behaviour anyway under Linux, where the listen()
622 argument is ignored; but not under BSD and on systems such as
623 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
624 YAZ-based servers should now be uniform across operating systems in
627 yaz-marcdump uses 64-bit file access on some systems. This is enabled
628 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
629 This allows yaz-marcdump to read large MARC batches (>2 GB).
631 Modified all YAZ source files - except the source which is auto-generated
632 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
635 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
636 corresponding to the existing *_setl() function. These allow option
637 values containing arbitrary valuues.
639 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
640 ZOOM_resultset_sort() in new applications. Its behaviour is identical
641 except that it returns an indicator of whether or not the sort
642 criterion was accepted (0 for OK, -1 for invalid).
646 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
647 MARC output rather than returning "new" buffer.
649 yaz-client warns about unknown init options.
651 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
655 Added support for SRW sort in Generic Frontend Server. Patch
656 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
657 sortKeys - or NULL if none is provided.
659 Fixed bug #307: It was impossible to specify indefinite/no timeout
660 for ZOOM_event. Special timeout value -1 now means indefinite timeout
663 Added support for multiple languages and charsets to be specified in
664 ZOOM. Each charset/language is separated by a blank. If negotiation is
665 in effect in init-response, Option
666 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
667 Code based on patch by Vasiliy Osadchuk.
669 Fixed bug #306: infinite recursion that occurred when calling
670 yaz_log_level_init as the first call (before other log level or
673 Fixed bug in scan handling in front end server: if preferred-Position-In-
674 Response was non-present, a NULL pointer referece was performed.
678 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
679 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
680 now defined for all those error codes. So instead of putting 109 in
681 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
682 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
684 Modified the yaz-marcdump utility to skip garbage bytes between MARC
687 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
689 Program yaz-client now exits and produces an error message if multiple
690 Z39.50 servers are specified on the command line (none or one allowed
693 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
698 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
700 Fixed bug #272: Preserve spacing for CCL terms.
704 Added support for virtual hosts and multiple backend servers for
705 the YAZ frontend server. The configution is XML based and
706 support specificition of CQL to RPN mappings and explain information.
707 See section "Virtual Hosts" in the YAZ manual.
709 Extended OPAC display utility. OPAC display utility renders
710 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
711 to supplement yaz_marc_decode_wrbuf.
713 Fixed a bug in MARC decoder that could caused it to crash for some
714 invalid MARC records. More diagnostics and warnings where added in
715 XML output (warnings, etc are stored in comments).
717 --- 2.0.34 2005/02/08
719 Fixes for UNIX domain sockets. Bug #261.
721 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
723 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
724 Added yaz_marc_subfield_str which defines subfield lead string which is
725 used in YAZ_MARC_LINE format. Default string is blank+$. Added
726 yaz_marc_endline_str which defines end of fields string used in
727 YAZ_MARC_LINE format. Default string is newline.
729 Experimental support for MarcXChange. This format can be produced
730 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
731 http://www.bs.dk/standards/MarcXchange.xsd
733 Added yaz-client commands scansize that sets maximum number of
734 entries to be returned by scan.
736 --- 2.0.32 2005/01/11
738 Added support for SRW scan in yaz-client and Generic Frontend Server.
740 * Added whereInList member to SRW Scan Term.
742 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
744 Fixed NMEM system to return aligned blocks on the smallest boundaries
745 that are suitably aligned for all possible types on the particular
746 architecture YAZ is being built for.
748 --- 2.0.30 2005/01/04
750 Fixed numerious warnings that was issued with newer versions of GCC.
752 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
753 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
756 Make YAZ Generic Frontend Server slightly faster.
758 Enhance (and reduce) logging for Generic Frontend Server.
760 Revert YAZ log system so that it flushes every write operation
761 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
763 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
764 instead of LOG_, due to name clash with syslog(3). LOG_ are still
765 present. New applications should define YAZ_USE_NEW_LOG=1 - this
766 will effectively disable old definitions.
768 --- 2.0.28 2004/11/09
770 Added yaz_log_time_format which specifies log format using
773 Added yaz_log_module_level which returns mask for a module. Value
774 is non-zero mask a if module is enabled; zero if disabled.
776 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
777 in include/yaz/cql.h.
779 Fixed bug #176: Dont throw diagnostics on empty SRU args.
781 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
783 Fixed bug #172: RPM builds does not enable SSL.
785 Doxyfile.in part of dist. Doxyfile generated by configure.
787 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
788 are given and the corresponding component does not exist.
790 Extend CCL documentation in YAZ reference. Describe r=r.
792 --- 2.0.26 2004/10/01
794 Fixed MARC->MARCXML conversion to properly deal with
795 fields, subfields, indicators having non-ASCII characters.
797 Fixed MARC->MARCXML conversion so that ASCII control characters
798 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
801 Added YAZ GFS support for conversion from Z39.50 surrogate
802 diagnostics to SRW surrogate diagnostics.
804 Bug fix: YAZ GFS did not return schema in explainResponse.
806 --- 2.0.25 2004/09/30
808 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
809 now converts recordSchema to elementSetName as well as schema URI.
811 Fixed bug in COMSTACK that prevented HTTP request packages from being
814 --- 2.0.24 2004/09/29
816 Added CCL facility r=r "range" which is similar to r=o "ordered" but
817 does not require white-space before and after the dash in a range, e.g.
818 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
821 Fixed a few AC_TRY_LINK configure tests that did not operate properly
822 due to new GCC removing "redundant" code.
824 Added yaz-client commands scanpos and scanstep that sets preferred
825 position and step-size for scan.
827 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
829 Added CCL utility ccl_qual_buf which parses one or more CCL
830 spec lines in a buffer.
832 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
833 of name and value - ignoring empty lines and comments.
835 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
837 Added odr_get_element_path which returns current element path for an
838 ODR handle. This utility is useful in error handling or user-defined
841 Added ODR_PRINT utility odr_set_stream which is is a more generic
842 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
843 to a write function and pointer to close function. The close function - if
844 non-NULL - will be called during odr_destroy.
846 Fixed bug in CCL parser where truncation char was not removed from
847 right side when truncation=both was in effect.
849 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
852 --- 2.0.23 2004/08/11
854 Fix buffer overrun in CQL parser when dealing with proximity (%).
856 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
857 to UTF-8/UCS conversion is now only based on codetables.xml.
859 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
861 --- 2.0.22 2004/08/06
863 Add support for more "commit changes" in ZOOM (uses Extended Services).
865 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
868 Yet another small fix for configure of SSL.
870 --- 2.0.21 2004/05/14
872 Fix SSL libs for configure when --with-openssl=DIR is given.
874 --- 2.0.20 2004/05/10
876 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
878 SSL comstack now uses yaz.pem certificate file on server side
879 by default. Certificate filename can be configured by calling
880 comstack function cs_set_ssl_certificate_file before cs_bind is used.
882 Fix bug regarding multiple calls to ZOOM_connection_connect.
884 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
886 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
887 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
889 ZOOM now allows inspection of X509 peer certificate for verification.
890 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
892 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
893 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
894 as "modular" but it simplifies things.
896 Added cs_get_peer_certificate to that returns peer X509 PEM.
898 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
899 NULL if SSL is unavailable.
901 Documentation about MARC decoding tools.
903 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
905 --- 2.0.19 2004/03/30
907 Rename CHANGELOG to NEWS to follow GNU style packing.
909 Fix bug with missing initialization of member in init_diagnostics.
910 This bug affects threaded version of GFS server.
912 --- 2.0.18 2004/03/20
914 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
917 Ensure zlib.dll is packed with Windows install.
919 --- 2.0.17 2004/03/17
921 Fix encoding of xsd:string to use text instead of CDATA.
923 Fix endless loop in CQL parser with unbalanced ".
925 Use a more compact way to store MARC-8 conversion tables.
927 --- 2.0.16 2004/03/16 Debian only
929 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
932 Update CQL parser to use new CQL 1.1 modifiers for booleans and
937 --- 2.0.15 2004/03/01
939 Another fix for decoding of XML packed records.
941 --- 2.0.14 2004/02/25
943 Fixes for Chunked encoding. White space not ignored after length spec.
945 Update NS and use default NS for SRW diagnostic elements.
947 --- 2.0.13 2004/02/23
949 Implement ZOOM_resultset_cache_reset which resets record cache.
951 Implement ZOOM_resultset_sort which sorts a result set.
953 Implement chunked HTTP transfer.
955 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
957 --- 2.0.12 2004/02/16
959 Added member 'schema' to bend_explain_rr structure so that backend
960 can specify explain record identifier. Defaults to Zeerex 2.0.
962 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
964 --- 2.0.11 2004/02/16
966 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
969 Added init command for yaz-client which sends "extra" init request.
971 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
972 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
974 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
976 Make ZOOM error code for "invalid query".
978 Fixed compilation for SSL which wasn't properly enabled for all platforms.
980 --- 2.0.10 2004/02/05
982 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
985 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
987 Added option -p <file> to make Generic Frontend Server to write PID file.
989 Added option -D to put Generic Frontend Server in background on its own.
991 Make ZOOM C recognize option "password". If unset, "pass" is used
992 (for backwards compatibility).
994 Fixed a bug in Generic Frontend Server that could make it crash if a
995 client sets characterSetNegotation bit, but didn't pass negotiation stuff
998 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
999 Must be issued before open, in order to be in effect.
1001 --- 2.0.9-6 2004/01/12 Debian/Windows
1003 Make the SRU server more picky WRT unknown params, etc.
1005 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1007 New YAZ client command, options, that sets Z39.50 options.
1009 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1010 options from a string of tokens (one token for each option bit).
1012 Update SRW diagnostic code messages.
1014 --- 2.0.9-5 2004/01/07 Debian/Windows
1016 Handle user defined stylesheet for SRW/SRU.
1018 --- 2.0.9-4 2004/01/06 Debian/Windows
1020 Fix bug in decoding of Content-Length.
1022 --- 2.0.9-3 2004/01/06 Debian/Windows
1024 Fix a bug with decoding of XML packed records.
1026 --- 2.0.9-2 2004/01/05 Debian only
1028 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1030 Fix bug in SRW/SRU diagnostics decoding.
1032 --- 2.0.9 2004/01/05
1034 Fixed bug in Generic Frontend Server which could drop records exceeding
1035 preferred message size. Reported and fixed by Irina Dijour.
1037 Fixed calculation of package size for structured records in Generic
1038 Frontend Server. Reported and fixed by Irina Dijour.
1040 Fixed namespace for SRW/SRU diagnostics.
1042 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1044 --- 2.0.8 2003/12/22
1046 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1047 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1050 CQL changes to reflect recent changes to the specification:
1051 * Documentation talks about context sets instead of index sets.
1052 * Documentation talks about indexes instead of qualifiers.
1053 * The CQL-to-PQF transformer's configuration file now uses
1054 "index.set.name = <attributes>" instead of the old form
1055 "qualifier.set.name = <attributes>". (Both forms are still
1056 understood but the latter is deprecated.)
1057 * CQL terms with no explicit index specified are now interpreted as
1058 cql.serverChoice instead of srw.serverChoice (which of course
1059 behaves exactly the same.)
1061 --- 2.0.7 2003/12/16
1063 MARC conversion can now generate ISO2709 output in another
1064 character set. yaz-marcdump uses this facility if you invoke it
1067 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1068 functions from there can be used from C++.
1070 --- 2.0.6 2003/12/04
1072 Frontend server now transfers memory from decoded packages to stream
1075 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1076 references to show up.
1078 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1079 the ZOOM Abstract API. The older names for the same options are still
1080 also supported for the benefit of old applications.
1082 ZOOM-C supports "implementationId" and "implementationVersion" options
1083 to go along with "implementationName". These allow the user code to
1084 specify identification strings to be sent to servers.
1085 Add OID for the new ExtLite attribute set.
1087 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1088 as requested/supplid by Ere Maijala <ere@atp.fi>
1090 For generic frontend server, reverse the order of
1091 "toolkit-supplied / application-supplied" strings sent as implementationId,
1092 Name and Version. Also, remove the spaces around the slash. This brings
1093 the GFS in line with the behaviour of ZOOM-C on the client side.
1095 Add function ZOOM_scanset_display_term.
1097 yaz-client shows scan displayTerm if present.
1099 Utility yaz-iconv is now installed by default along with the man page
1102 Extend configure check for OpenSSL to use pkg-config where available (such
1105 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1106 server to specify uid/gid/mask for socket using the format
1107 unix:[user=uid,][group=gid,][umask=mask,]file=path
1108 If file= is omitted the existing format is assumed, e.g.
1110 in which case the mask is 0666 (rw for everybody).
1112 Major restructure of YAZ source. All source in libyaz is in src directory.
1113 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1114 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1116 Added man page for utility yaz-marcdump (used to be called marcdump).
1117 yaz-marcdump is installed by 'make install'.
1119 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1120 of incoming package failed.
1122 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1124 Change prototype of odr_perror: add const to message string.
1126 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1128 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1129 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1130 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1131 DNS lookup. There should not be any compatibility problems with this
1132 assuming that blocking=1 or 0 is used.
1134 Fix bad reference in UNIX comstack in function cs_addrstr.
1136 Fix for compilation on AIX.
1138 The generic front-end server (server/seshigh.c) now supports returning
1139 Init diagnostics to the client in User-information-field, in
1140 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1143 --- 2.0.4 2003/09/04
1145 Allow any CQL relation (not just all,any,exact,scr).
1147 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1148 that features the same UI.
1150 Implemented command update0 in YAZ client which is equivalent to
1151 update but uses old of Ext Update ASN.1.
1153 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1154 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1155 Previously no OID was used for this info.
1157 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1158 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1159 returns 'malformed search term' otherwise.
1161 SortResponse member resultCount now set to NULL in sort handler of
1164 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1167 Add three new utility functions for translating OIDs between various
1168 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1169 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1170 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1171 char *oid_to_dotstring(const int *oid, char *oidbuf);
1172 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1174 Reverted modifications for ES Update definition for z_IU0Update
1175 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1176 is back to YAZ 2.0.2.
1178 String value attributes for CCL parser.
1180 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1181 which their FirstSearch server returns in Init responses, sometimes
1182 carrying useful diagnostic information when Init fails. This has the
1183 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1184 "z39.50/oclcui.asn", where its definition is somewhat different from
1185 what OCLC document on their web-site, as required to interoperate with
1188 Support for anonymous authentication in yaz-client. Use the command
1191 * Fix the OID of the Index Data-local "admin" Extended Service from
1192 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1193 the 1000, which indicates a locally-defined OID, was a mistake.
1195 --- 2.0.3 2003/06/20
1197 Fix CCL directive @case handling so that it affects string match for
1198 both CCL keywords and qualifiers.
1200 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1201 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1202 Decoder has been updated with ASN.1 changes as listed in
1203 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1204 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1205 z_IUUpdate, remains unchanged.
1207 ZOOM_record_get may now return a record in a specific character set.
1208 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1209 "from" is the character set of record as returned by target. "to" is
1210 the character set to be returned. If omitted, "to" is UTF-8.
1212 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1214 New ODR utility, odr_getelement, which returns name of element for
1215 which encoding/decoding failed.
1217 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1218 in cases where a required element was omitted.
1220 Bug fix: some MARC8 sequences were not converted.
1222 New ZOOM option "step" which specifies number of records to be
1223 retrieved in one chunk. Used in conjunction with "start" and "count".
1225 SRW support for yaz-client. Use scheme http: to use it, e.g.
1228 yaz-client no longer does (un)intelligent character set conversions
1229 by default. Can be enabled with charset and marc_charset commands.
1231 xmalloc trace fix for 64-bit systems such as DEC alpha.
1233 Solaris 2.6 compile fix.
1235 New function, cql_strerror() translates SRW error codes, as returned
1236 by cql_transform_error(), into human-readable English strings. Used
1237 in yaz-client diagnostics when appropriate.
1239 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1240 converts it into a type-1 query which is sent to the server. This
1241 makes CQL available for use with all Z-servers, as opposed to the tiny
1242 minority that can handle CQL queries themselves.
1244 --- 2.0.2 2003/04/28
1246 New Debian package layout similar to the Redhat Package layout.
1248 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1249 and search result respectively.
1251 --- 2.0.1 2003/04/25
1253 Redhat package is now several packages: libyaz (runtime libraries),
1254 libyaz-devel (development and documentation, and yaz (utility programs).
1255 Package spec file by Morten Bøgeskov.
1257 New member 'schema' in struct bend_fetch_rr which the name of requested
1258 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1259 handler MAY set this to reflect the schema of the returned record.
1261 New member 'display_term' in struct scan_entry. GFS now sets member entries
1262 and allocates scan entries to be filled by user scan handler. In previous
1263 version, entries member was allocated by the scan handler. That still works,
1264 but the GFS will ignore member display_term - assuming it was NOT set by
1265 the handler. The fact that the GFS now allocates the entries both allows
1266 for new members and makes a scan handler easier to write.
1268 Fix CQL lex buffer overflow.
1270 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1271 SRU default recordPacking is string.
1273 SRU protocol support for frontend server.
1275 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1277 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1279 Added scan for the ZOOM shell (zoomsh).
1283 * String Identifers for Schemas (Amendment 5).
1284 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1285 Old definition for schema
1286 Odr_oid *schema; /* OPT */
1291 Z_InternationalString *uri;
1292 #define Z_Schema_oid 1
1293 #define Z_Schema_uri 2
1296 * resultCount parameter to Sort Response (Amendment 1).
1297 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1299 Support for SRW 1.0 over HTTP. This is an optional feature and
1300 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1303 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1304 on the same port. SRW SearchRetrieveRequests are mapped
1305 to bend_init,bend_search,bend_fetch,bend_close.
1307 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1309 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1310 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1312 ZOOM connections are SRW based if schem http is used for hostname
1313 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1314 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1316 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1317 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1318 distance=n, order=true/false, relation=le, prox unit=word. If
1319 n is omitted, distance 1 is used.
1321 Fixed problem with C compiler include path in wrong order.
1323 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1324 on Solaris. Patch from Ko van der Sloot.
1326 New MARC decode API. All new functions operate on a yaz_marc_t
1327 handle. The most important new functions are: yaz_marc_create,
1328 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1329 decode and destroy respectively. Decoder can produce formats
1330 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1331 include/yaz/marcdisp.h.
1333 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1334 to UTF-8, UCS-32, wchar_t or Latin-1.
1336 * Prototypes for yaz_iconv_-functions moved to separate header
1337 include/yaz/yaz-iconv.h.
1339 Make a few private functions 'static' in unix.c. This prevents
1340 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1342 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1343 are set when Init Response is received.
1345 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1346 but returns diagnostic set as well.
1348 New function yaz_strerror which is a portable wrapper for
1349 strerror/strerror_r/GetLastMessage.
1351 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1352 is returned for MARC. If type is "oai", then OAI MARC is returned.
1354 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1357 --- 1.9.2 2002/11/26
1359 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1361 Fix bad race conditions on SIGTERM and terminate gracefully in
1364 Move retrieval (data1) module to Zebra since nobody seems to be
1367 Add GRS-1 render for ZOOM using same format as yaz-client.
1369 --- 1.9.1 2002/10/05
1371 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1373 Fix broken ESpec handling in data1 module.
1375 SGML reader parses comments and makes them part of the data1 tree.
1377 Added several type casts so that YAZ compiles as C++ code.
1379 ZOOM didn't handle PDU encoding failures properly.
1381 Added more Bib-1 diagnostics (approved extensions).
1383 GNU configure: better check for iconv.
1385 More portable use of accept, getpeername. Check for socklen_t. Use
1386 int/size_t if socklen_t is not defined.
1390 PQF parser rejects bad queries - including those with extra
1391 characters in them. PQF parser used to silently ignore that.
1392 Cleaner API for PQF added, which allows you to get detailed
1393 error information for bad queries (see yaz/pquery.h).
1395 Fixed bug in ZOOM_record_get for type "database".
1397 Implemented mini iconv library supporting conversions between
1398 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1400 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1402 --- 1.8.9 2002/08/20
1404 Fixed ZOOM C record cache so that preferredRecordSyntax and
1405 elementSetName is used to check for already fetched records.
1407 --- 1.8.8 2002/08/02
1409 Added three members in bend_initrequest structure to facilitate
1410 character set negotiation.
1412 Fixed a bug in frontend server that could cause indefinite
1413 loops under rare conditions.
1415 Revised character set utilities (charneg.h) so that encoding
1416 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1418 For PQF, directive @term <type> sets term type for Scan/Search.
1419 Here <type> is general, string, numeric, null. The term type
1420 is inherited - just like @attr.
1422 New call odr_set_charset that sets character set conversion for
1423 international-strings on a ODR stream. Prototype is:
1424 int odr_set_charset(ODR o, const char *to, const char *from);
1425 The InternationalString is still represented as C string in YAZ
1426 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1427 won't). On the protocol level, you can use any encoding.
1429 Support for UNIX sockets in ZOOM.
1431 Solaris recv sometimes returns errno == ENOENT. It is treated as
1432 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1434 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1435 both client and server. Code by Morten Bøgeskov.
1437 --- 1.8.7 2002/05/22
1439 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1440 that they can be used directly from Visual Basic. You must recompile
1441 your windows APP if you're using ZOOM.
1443 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1444 Commands "lang" and "charset" sets language and character set respectively.
1445 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1446 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1448 Attributes from multiple CCL fields may be OR'ed rather than merged
1449 using directive "@field or". Fields are still merged by default -
1450 equivalent to "@field merge".
1452 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1455 Fixed bug in zget for parameter ExtendedServicesResponse.
1459 --- 1.8.6 2002/03/25
1461 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1463 Client displays USR.1:SearchResult-1 (hits per term).
1465 Additional Search Info for search in Generic Frontend Server.
1467 Fixed CCL parsing of "field=s".
1469 WIN32 installer - using the excellent NSIS software from nullsoft.
1471 Fixed CCL parsing of "field = - <number>".
1473 Added function yaz_marc_decode that decodes MARC for line mode
1474 display or XML (similar to that used by JZKit).
1476 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1477 Z39.50. But ISO/ILL was, however.
1479 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1480 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1482 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1483 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1485 --- 1.8.5 2002/02/03
1487 New YAZ client features: Command completion and new commands:
1488 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1489 Code provided by Jacob Poulsen.
1491 New call oid_trav, that visits all registered OIDs via callback.
1493 Function ZOOM_record_get now returns const char pointer rather than
1494 void pointer. It saves a lot of type casts.
1496 For YAZ client, command "auth" now allows you to set authentication
1497 in IdPass style. It is enabled when three tokens are given - order
1498 is user, group and password.
1500 Fix memory leaks in MARC record handling for ZOOM.
1502 New option for YAZ client, -k <kilobytes> that sets
1503 maximum record size. Similar to -k option for generic frontend
1504 server and yaz-ztest.
1506 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1508 Prefix query parser reports "fail" when bad attribute set is given.
1510 Fix in MARC decoder. Proximity logging. Fix for attribute set
1511 in scan handler for server. Patches by Shigeru Ishida.
1513 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1516 Configure option --with-openssl=<dir> now works when a directory is
1517 specified. Patch provided by Morten Bøgeskov.
1519 New option for YAZ client, -u <auth>, that sets authentication.
1521 ZOOM fix: error information was sometimes "missing", since error
1522 was cleared/reset too when it shouldn't.
1524 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1526 --- 1.8.4 2002/01/04
1528 Scan for ZOOM API. New object ZOOM_scanset. New functions
1529 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1530 ZOOM_scanset_destroy.
1532 New ZOOM function, ZOOM_connection_last_event, that returns type
1533 of last event (such as "receive data", "send data", "apdu received",
1536 New ZOOM option, schema, that specifies schema for retrieval.
1538 New CCL feature. Qualifiers can be aliases for one or more
1539 other qualifiers (if more than one is given, OR is used).
1541 ZOOM uses named result sets if target supports it.
1543 Two new YAZ client commands: . (dot, which sources a script of YAZ
1544 client commands), and ! (to execute shell command.). Implemented
1547 Working on Debian packages.
1549 --- 1.8.3 2001/11/19
1551 YAZ client enables named result sets only if target supports it.
1553 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1555 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1556 with key="host" to get same result.
1558 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1559 Function Z3950_resultset_record(s) returns references to records
1560 "owned" by resultset. To become owner use Z3950_record_clone.
1562 Function z_ext_record handles Extended Services. Thanks to
1565 --- 1.8.2 2001/11/12
1567 CCL Parser fix: ignore token comma when dealing with and-lists.
1569 Documentation updates for COMSTACK.
1571 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1572 Changed prototype Z3950_records. For some functions, int parameters
1573 were changed to size_t.
1575 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1578 New MARC decode/display function, marc_display_exl, which properly rejects
1579 non-ISO2709 records. YAZ client uses it.
1581 --- 1.8.1 2001/10/29
1583 Fix bug: local attribute set wasn't set correctly in PQF strings.
1587 * Old Z39.50 codecs no longer supported.
1589 Added ZOOM C binding. See http://zoom.z3950.org/
1591 Renamed states for COMSTACKs to avoid confusion with events.
1593 Implemented cs_look and proper cs_rcvconnect.
1595 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1597 Configure detects POSIX threads on OpenBSD.
1599 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1600 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1602 When error is returned from present handler, non-surrogate diagnostic
1603 is returned in present response (and fetch handler is no longer called).
1605 * Minor adjustments to pquery parser (PQF). Token characters may be
1606 escaped by using backslash (C-style).
1608 PQF parser allows string attribute values to be specified. For @attr,
1609 non-numeric characters after the equal-sign are treated as strings
1610 (e.g. @attr 9=title).
1612 CCL trunction character may be defined (@truncation in file)
1614 * function zget_ExtendedServicesRequest sets waitAction to
1615 waitIfPossible (was wait).
1617 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1620 CCL operator names may be set in field definition files (CCL_bibset).
1621 See ccl/bib1 for an example.
1623 Fixes in ASN.1 compiler for C++ compatibility.
1625 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1626 and "op_or" to avoid conflict with C++.
1628 Fixed problem with GNU readline detection on Redhat 7.0.
1630 Added step-size for Scan backend handler.
1632 Fixed bug that made the frontend server crash when no attribute
1633 set was specified for scan.
1635 Front-end server automatically switches to original working directory
1636 when installed as an NT service. Previously -w had to be specified to
1639 Added extended attributes for retrieval module (data1), so that data1
1640 records carry d1_readXML/SGML attributes. d1_read also supports
1641 null-data rules ( <tag/>)
1643 On UNIX when POSIX threads are available, a separate library libyazthread
1644 is created. Programmers should link with that library and the yaz library
1645 when using threads. The reason for the split was that some applications
1646 on Linux, such as Apache, doesn't work well when using shared objects that
1649 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1650 (or any frontend server) in SSL mode by specifying ssl: followed by
1651 address. Only tested on UNIX.
1653 Added feature for CCL module. Virtual structure s=al or s=ol generates
1654 and-list and or-list respectively instead of phrase search.
1658 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1659 log_mask_str. This was done to avoid name conflicts with other libraries
1660 (such as other PHP extensions).
1662 Added raw OID member for preferred record syntax (request_format_raw)
1663 and returned record syntax (output_format_raw) for backend fetch method.
1665 Config file yaz-config now accepts options so that it returns specific
1666 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1668 Shared library support for UNIX using GNU libtool.
1670 * Modified backend interface. Request/Response struct's replaced by
1671 one read/write C struct. For example bend_fetchrequest and
1672 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1673 Every handler - even search has to be registered in bend_init
1674 handler. This means that the YAZ library no longer refers to
1675 external functions and it makes it possible to make the whole
1676 thing a single DLL/SO.
1678 Added Segment handler for backend server.
1680 Added Zmbol/Zebra administrative functions to YAZ client.
1682 Threaded frontend server on UNIX (when POSIX Threads are available).
1683 Starting the server with option -T enables multi-threading.
1687 Added configure option --enable-comp/disable-comp to control use
1688 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1689 located in sub directory asn.
1691 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1692 in ${exec_prefix}/bin along with the other programs yaz-client and
1695 GNU automake used to maintain makefiles.
1697 Added several OID's.
1699 Changed retrieval module so that we can load records with no abstract
1700 syntax defined. Tagpaths in these records are fully composed of string
1703 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1707 On UNIX, the generated makefile now supports a proper 'make install'.
1708 The prefix can be set via GNU configure to set the install location
1709 (default is /usr/local).
1711 * YAZ programs client and ztest were renamed to yaz-client and
1712 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1713 locations, such as /usr/bin,/usr/local/bin,etc.
1715 * YAZ Header files were moved from include to include/yaz. YAZ Header
1716 files are referred to as include <yaz/log.h> rather than <log.h>.
1717 The YAZ include path (-I ..) is therefore the same as before. Programmers
1718 should update their #include statements or use -Ipath/include/yaz
1719 instead. The main motivation for doing this change is that YAZ header files
1720 can be installed in "standard" locations /usr/include,/usr/local/include
1721 without introducing conflicts, since ALL YAZ header files are stored
1722 in subdirectory yaz (under /usr/include for example).
1724 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1725 rather than project/workspace files. We switched because project files
1726 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1729 Changed name of logging function, logf, to yaz_log, to prevent name
1730 clash with some math-log functions. The YAZ header log.h defines logf
1731 to yaz_log (#define) so there should be no incompatibilities by this
1734 Added bend_start/bend_stop handlers for server. These handler are
1735 called on start/stop of server. For windows they are called whenever
1736 a service is started/stopped.
1738 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1739 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1740 in util/yc.tcl. The auto-generated C code structures are, in a few
1741 cases, incompatible with the old decoders. There are differences in the
1742 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1743 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1744 The preprocessor variable ASN_COMPILED is defined when the compiled
1745 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1746 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1747 wish to use the old encoders/decoders you can specify --disable-yc
1750 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1751 version so that it supports both new - and old version of DB Update
1753 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1754 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1755 change. The name parameter can be set to 0 in which no name is specified
1756 for the construction. The macros odr_implicit and odr_explicit sets name
1757 parameter to zero for the construction involved. New macros
1758 odr_implicit_tag and odr_explicit_tag are similar to the others,
1759 except that a name parameter is added. For programmers' that don't use
1760 ODR they probably only need to change the call to z_APDU and z_External.
1762 Added access control facility by interfacing the TCP wrapper library.
1763 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1764 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1765 name of the daemon and enables the access control as specified in
1766 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1768 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1769 den Dool <H.M.vdnDool@kub.nl>.
1771 Added reference ID parameter to most functions in server API - refer
1772 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1774 Changed name of ccl library to libccl.a (was ccl.a).
1776 Fixed bug in decoder for Explain (Category TargetInfo).
1778 Added support for GNU readline in client. Thanks to Jacob Poulsen
1779 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1781 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1782 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1783 IMPLEMENTATION! This change was made to the development version before
1784 the ZIG decided to retract the amendment. If any users MUST be
1785 compatible with the original Update definition, PLEASE CONTACT US, and
1786 we will include a separate definition corresponding to the old Update
1787 ES. Note that because of the change to the ASN.1 of the
1788 TaskPackageRecordStructure we cannot define a single structure that
1789 will support both versions.
1791 * Added const modifier to buffer parameter for some ODR/BER encoding
1792 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1793 completeWAIS, odr_dumpBER.
1795 Fixed bug in client.c which caused a crash when a scanResponse didn't
1796 contain positionOfTerm.
1798 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1799 * will cause an error in a client if a non-YAZ target sends both a
1800 * list of Scan entries and non-surrogate diagnostics.
1802 Retrieval module enhancements. Tag sets may be typed in the reference
1803 to it. From the .abs-file the "tagset" directive takes a third optional
1804 integer type for the tag set referenced. From a .tag-file the "include"
1805 directive takes a third optional type as well. The old "type" directive
1806 in the tag set itself is still recognized but acts as the default type
1809 Backend interface change. Individual Scan terms returned from bend_scan
1810 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1811 in include/backend.h.
1813 Retrieval module enhancements. Multiple tag sets and attribute sets may
1814 be specified in abstract syntax specs. Revised the error/warning for
1815 logging messages reported by the retrieval module when reading the
1818 Object Identifier system (oid_..) changed. The API is backwards
1819 compatible but the oid-routines now allocates new OID's when needed.
1820 Raw OID's may be specified in oid_getvalbyname.
1822 YAZ now uses GNU configure to generate Makefile(s).
1824 * Minor changes in some of the member names of DeleteResultSetRequest and
1825 DeleteResultSetResponse. See include/proto.h.
1827 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1828 and added member 'languages' in TargetInfo (which was missing).
1830 Changed the way attribute sets are handled in the retrieval
1831 module. These are now cached, just like the abstract syntaxes
1834 Changed YAZ so that it links with compiled ASN.1.
1836 Added Explain-schema definitions and mapping routines. The following
1837 Explain categories have been implemented: AttributeDetails,
1838 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1840 Fixed minor bug in Windows version of Server Library.
1842 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1844 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1846 Added EXTERNAL: UNIverse Resource Report (non-standard).
1848 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1849 ENUMERATED and SET OF.
1851 * Added 'const' to some of the char pointer arguments for the
1852 functions, data1_read_node, data1_getelementbytagname,
1853 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1856 Fixed bug in data1_insert_taggeddata - the last_child member of
1857 parent wasn't initialised.
1859 * Changed data1_read_record and data1_read_node so that the supplied
1860 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1861 doesn't refer to any parts of the "SGML"-buffer.
1863 Fixed bug in server library (Windows version of statserv_remove).
1865 * Changed code so that it compiles as C++. The type definition
1866 of Odr_fun which is a member of Odr_arm was changed. The result is,
1867 that an explicit typecast is needed for the fun pointer when
1868 using Odr_arm - as in:
1869 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1871 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1873 Implemented the new structured date and time definition as approved
1874 by the ZIG. Added schemaId element to the specificTag in Espec-1
1875 (also approved at the last ZIG). Thanks to RVDM.
1877 Added some Object identifiers (RVDM).
1879 Changed the Update Extended Service (RVDM).
1881 Added command "refid" to client which specifies referenceId for
1882 the following requests.
1884 Implemented extended service handling for server. See ztest.c
1885 for an example as well as backend.h. New handlers are registerd
1886 in the Init handler.
1888 * Changed interface for sort in server.
1890 Added new members to statserv_options_block. It allows a server
1891 to read options from another source than just the command line. Thanks
1892 to Charles Woodfield.
1894 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1895 renamed to zboolean. Some C++ compilers complained about the name.
1897 Minor changes to gils.abs. Added index 's' (sort) on title
1898 and date/time-last-modified.
1900 --- 1.4pl2 1998/1/30
1902 Fixed bug in server library regarding inetd mode (-i). This bug
1903 was introduced by release 1.4.
1905 --- 1.4pl1 1998/1/29
1907 Added sort facility in client and backend server interface.
1909 Fixed problem with dependencies in Makefile(s).
1911 Fixed bugs for encoders/decoders of extended services and
1914 Implemented sub-tree feature for schemas. Sub-trees are
1915 referenced in *.abs-files. See explain.abs for an example
1916 of the use of this feature.
1918 Modified bib1.att; local attributes for ANY didn't include
1919 ANY itself (only affects use of the retrieval module).
1921 Fixed bug in plain SGML reader in function data1_read_node:
1922 tags with prefix "var" was incorrectly interpreted as variants.
1924 Added feature "sub-schemas" to enable references to - and definitions
1925 of - group of elements.
1927 * Removed member parent from type data1_element (in data1.h).
1929 Implemented function odr_nullval() that returns the value of
1932 * Removed member num_children from data1_node (in data1.h).
1934 Made NT service interface part of the server library. The
1935 function statserv_main uses the NT service when required and
1936 calls the statserv_start / statserv_close routines.
1938 Routine zget_SearchRequest and zget_PresentRequest fills
1939 resultSetName/Id member with "default" instead of "Default".
1941 Fixed memory leak in server. Request queue member wasn't freed.
1943 Fixed nmem_exit so that memory is freed.
1947 Revised the CCL parser utility to be thread safe.
1949 Added function, oid_ent_to_oid, to replace the function
1950 oid_getoidbyent, which is not thread safe.
1952 * Added nmem_init and nmem_exit to initialize and release
1953 NMEM resources. Function nmem_init should be called once in the
1954 initial thread before NMEM/ODR is used. statserv.c and client.c
1955 have been changed accordingly. The change was necessary to make
1956 NMEM thread safe. The NMEM memory pool is shared amongst threads
1957 in a process. Unix-based applications will still work fine without
1960 Added NT Services interface for the the Z39.50 (statserv) Server.
1961 Refer to the ztest.c source on the usage.
1963 Windows 95/NT port using MSVC5.0. Project files are included in the
1966 * Defined new 'global' handle for the retrieval (data1) system. The
1967 new handled, data1_handle, describes the state of the data1 system.
1968 This handle is passed as first argument to virtually all
1969 data1 related routines. The functions data1_create and data1_destroy
1970 creates and destroys a data1 handle respectively.
1972 Added ODR encode stream member to all backend request structures
1973 init, search, scan etc. This stream should be used to allocate all
1974 memory used for the response when thread safe operation is needed.
1976 Changed the comstack utility, cs_addstr, to be thread safe. The
1977 returned hostname string returned by the function is now part the
1980 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1981 function. The cs_straddr takes a COMSTACK handle as argument, so this
1982 function must be used after cs_create and before bind/connect.
1983 This function is thread safe.
1985 Moved test server to 'ztest' directory - generic server code still
1986 in 'server' directory.
1988 Made prefix query (pquery.c) utility thread safe.
1990 Added new function modifier YAZ_EXPORT to 'export' public DLL
1991 functions when using windows (see include/yconfig.h).
1993 Added definitions to the OID database (util/oid.c) (RVDM).
1995 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1997 Added call to ccl_rpn_delete in client program.
1999 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2000 release of RPN structure.
2002 Added support for C++, headers uses extern "C" for public definitions.
2003 With input from RVDM.
2005 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2006 Thanks to Ronald van der Meer (RVDM).
2008 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2010 Added support for private extensions to the OID database
2011 (oid_setprivateoids()). Thanks to RVDM.
2013 Added optional, physical ANY (key replication)
2015 Fixed null-reference problem in GRS-1 output filter.
2017 Proximity operator added to Prefix Query Format (PQF).
2019 In test client command "base" accepts multiple databases.
2021 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2025 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2027 Smallish bug-fixes in the new encoders/decoders (explain).
2029 Bug fixed in DeleteRequest.
2031 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2033 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2035 Added SOIF syntax (using private OID for now) to retrieval module and client.
2037 Added Update extended service.
2039 Added SearchResult-1 additional info structure.
2041 Added optional CCL (ISO8777) interpreter as separate module. Available
2044 --- 1.2 1996/6/10 (1st anniversary release)
2046 Added Summary record syntax. Lightly tested.
2048 Added OPAC record syntax. Untested.
2050 Added ResourceReport service encoders/decoders. Untested.
2052 Fixed bug in z_Unit - wrong tagging on unitSystem.
2054 Fixed bug in the DiagRecs decoder.
2056 Added options for max PDU size and session timeout to frontend-server.
2058 Added documentation of query-language parsers and other supporting utilities.
2060 [frontend-server] Added Attribute set to the bend_scanrequest API.
2062 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2063 surrogate diagnostics were generated.
2065 [retrieval] Allow multiple local values for attribute.
2067 [retrieval] Allow multiple attributes per element in .abs files. index type.
2069 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2071 --- 1.1pl2 1996/4/10
2073 Minor changes, mostly specific to Zebra's requirements (retrieval)
2077 Repaired bug in frontend server when running multiple listening
2078 endpoints in dynamic mode.
2080 z_External() now won't break if a known, ASN.1 value comes encapsulated
2081 in an octet-string. The value will pass through unmodified in an Odr_oct.
2083 Added a bit of code to the demo client to decode & display
2084 ASN.1-structured records represented in the octet-aligned branch of
2085 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2087 Added z_ext_getentbyref() to the ASN module. Doc updated.
2089 * Completed the SCAN definition in the ASN module. This may break SCAN
2090 code based on older YAZ-versions at compile-time. The fix is easy -
2093 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2094 under the SCAN definition. Remember to initialize this, server-people.
2096 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2097 that this does not extend to ODR and ASN.
2099 Comstack allows insertion of established socket (primarily for
2100 inetd-operation of servers). Doc updated.
2102 Front-end server can now start from the inetd in TCP mode. Doc
2105 --- 1.0pl4 1996/1/24
2109 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2110 the rank and record number.
2112 Adjustments to the frontend server.
2114 Fixed diagnostic BER dumper. It ignored the file argument.
2118 Various changes to retrieval module.
2120 Changed the union discriminators of the protocol files from enums to
2121 ints paired with #defines.
2123 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2126 *Changed operator in the RPN structure to 'roperator', again to avoid a
2129 Fixed problems in Explain decoders/encoders.
2131 --- 1.0pl2 1995/12/6
2133 Memory bug in log module fixed.
2135 --- 1.0pl1 1995/12/5
2137 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2139 Bug in Explain DatabaseInfo module fixed.
2141 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2145 The shift to v1.0 signals that we now consider the *core* functionality
2146 of YAZ reasonably stable (the core being more or less equivalent to
2147 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2148 tested (Explain not at all - though that will happen soonish).
2150 Minor changes to code to support Windows port.
2152 Various minor changes after we're getting to use GRS-1 & co. more.
2154 Added Espec-1 format.
2156 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2157 of the protocol and it cannot be selected when encoding (maps into 'string'
2158 when decoding). Needed to talk to some servers.
2160 Demo client can request simple element set names.
2162 Added Diagnostic Format encoders/decoders.
2164 Added simple Close handling to frontend server (no hooks for resource
2165 reporting yet), and demonstration client.
2167 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2169 --- 1.0b3 1995/08/24
2171 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2172 handled incorrectly when records were requested in the searchResponse. This
2173 will only affect you if you use the frontend-server.
2175 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2176 Test-client will ask for and print GRS1. Ztest will return dummy records
2179 Added Explain encoders/decoders to the service-level API. Untested.
2181 Added Extended Services: Item Order encoders and decoders to the Service-
2182 level API. Untested. We could use a recent copy of the pertinent bits
2183 of the ILL protocol to add those bits.
2185 Added diagnostic format 1 encoders/decoders to the service-level API.
2188 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2189 odr_cons.c, which causes a more correct output.
2191 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2192 was always set to 0 when no records were requested in the searchRequest.
2194 * Added better external-handling. This shouldn't harm old code that
2195 *encodes* externals. It can break code that looks for a
2196 'single-ASN1-type' representation, since those types that are known
2197 are now decoded immediately. Look at the SUTRS sample code in
2198 seshigh.c and client.c. Documentation updated.
2200 Handling of structured records in bend_fetchresponse. Length -1 marks
2201 structured record, type is deduced from format field.
2203 --- 1.0b2 1995/06/27
2204 Fairly quick maintenance release to add SUTRS support.
2206 Fixed handling of SUTRS records in the demonstration client.
2208 * Added format field to the bend_fetchrequest and bend_fetchresponce
2209 structures of the backend API (frontend server). When the record is
2210 returned, the value of the format field is mapped to an OID. The
2211 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2212 of the record. The special value VAL_NONE in the bend_request means
2213 that no specific format was requested by the client. Documentation
2214 updated accordingly. Test server (ztest) will return a fixed dummy
2215 SUTRS record if your client requests SUTRS.
2217 Documentation updated accordingly.
2219 You can now set external libraries and RANLIB support in the top-level
2223 First public release.
