1 Implemented a way to perform scan in a result set using Z39.50. This
2 is achieved by attaching the result set name in the characterInfo
3 (type InternationalString) of OtherInformation in the Scan Request PDU.
4 The result set is identified in the otherinformation by the new OID:
5 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
6 This allows for scan in result set and faceted search . Zebra did some
7 of this in the APT term using attribute type 8 and value being result
8 set. Using the OtherInformation approach for this is cleaner and easier
9 to work with in proxies and the like. This facility can be used in
10 yaz-client using new command setscan which takes a result set as first
11 argument, start position (APT) as second.
13 Changed decoding of SRU XML packed records to deal with servers that
14 have recordData with XML data with multiple root nodes. Also make
15 comparison for recordPacking case insensitive. Again, one server
16 returns "XML" where others return "xml".
18 For SRU responses allow Content-Type application/xml as well as text/xml.
22 Fixed bug in character set conversion of BER strings. Bug introduced
27 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
29 For OID class, use oid_class consistently.
31 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
34 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
35 character set for bibliographic information interchange". By Giannis Kosmas.
37 Added documentation on new OID API.
41 Changes to generic frontend server interface: added new member
42 'query_charset' for bend_initrequest structure. A backend init handler
43 should set this member to its native character set for query terms.
44 When defined, the frontend server logic will announce this character set
45 to a client if the negotiationModel bit is set by the client. All server
46 implementors are encouraged to specify this. If a backend server does not
47 specify this a warning is issued using yaz_log(YLOG_WARN,..).
49 Added CCL utility to remove terms (stop words) from resulting RPN
50 tree. This is handled by functions with prefix ccl_stop_words_ .
52 New ZOOM C option, "rpnCharset", which allows client-side conversion of
55 Clean-up the CCL API. Moved some internal structures from ccl.h to
56 private header cclp.h. Changed ccl_parser_create so that a Bibset must
57 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
58 This is replaced by ccl_parser_find_str which takes a string instead.
60 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
61 libyaz.la is the core of YAZ except the generic frontend server and
62 does not depend on POSIX threads anymore. libyaz_server.la is the
63 generic frontend server facilities and uses POSIX thread functionality
64 if available. The libyaz.la no longer depends on POSIX threads because
65 the number of global structures is limited. NMEM no longer re-uses blocks
66 between threads ; it simply free's memory immediately but allocates in
67 "large" chunks as usual. We don't expect any performance penalties
68 because of this. The yaz_log system is still using a global log_level so
69 caution must be taken when modifying it with yaz_log_init_.. +
70 yaz_log_mask_str. This, however, should not cause any trouble because
71 these functions are called during initialization of application code
72 anyway. `yaz-config --libs server` returns libs for server applications;
73 `yaz-config --libs` returns libs for non-server applications.
75 New OID database - with public definitions in oid_db.h. Removed old OID
76 database including the head oid.h and definitions such as enum oid_value
77 and struct oident. The new OID database uses the same string names as
78 before but the 'protocol' is gone. There are now only two representations
79 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
80 converts from string to OID; functions with prefix yaz_oid_to_string
81 converts the other way.
83 Change to emit_term() in CQL-to-PQF query translation: when a term has
84 the /regexp relation modifier, do not process it for leading and
85 trailing "^" and "*", which have quite different meanings in regular
88 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
89 write handlers no longer carries a 'last' parameter. This will make
90 yaz_iconv flush "less" characters. A flush is performed by call to
91 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
93 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
94 removed, because function yaz_query_to_wrbuf does the same.
96 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
97 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
99 Deprecated MARC utility functions removed.
101 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
104 Branch split: YAZ_2_1_55_branch
106 --- 2.1.54 2007/03/16
108 Fix to ZOOM-C so that transparent reconnection is properly handled on
109 connections that are in asynchronous mode.
111 Fixed compilation on OpenBSD 4.0.
113 Large strings in GRS-1 records are now properly displayed in yaz-client.
115 Added character conversion support for "advancegreek"; based on patch from
118 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
119 sequence is met. Before the error was not set so it would be unknown.
121 Adjust yaz-marcdump MARC reader so that it skips until record separator
124 --- 2.1.52 2007/03/07
126 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
127 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
128 fd_set structure used as a bitmask for the FDs to be selected on.
130 Using ACX_PTHREAD macro to check for POSIX threads.
132 Fixed have-vsnprintf check.
134 --- 2.1.50 2007/02/23
136 Fixes for configure on BSD. Bug #900.
138 Added snprintf/vsnprintf wrappers for systems that don't have
139 limits (heavens forbid).
141 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
142 created before all previous tasks were completed and removed from the
143 task queue, the new task could be removed by a mistake.
145 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
147 Implemented pass-through CQL-to-PQF conversions. Bug #861.
149 Fixed bug #832: Problem with MARC/charset in yaz-client.
151 Fixed bug #668: save command line history for yaz-client.
153 Fixed bug #830: pkg-config support.
155 --- 2.1.48 2007/01/23
157 Extended ZOOM result set options with two options that may be read by
158 a client: resultSetStatus and presentStatus with values as specified for
160 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
162 Fixed bug #827: Using SSL fails on Debian etch.
164 Fixed bug #826: Weird looking chars for set of MARC records.
166 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
167 that is treated as an ItemOrder with itemRequest being an XML document
168 external. The value of "doc" is the content.
170 Extended the GFS search facility. New member of bend_search_rr
171 'estimated_hit_count' signals that hits is known to be an estmate
172 (higher or lower than real hit count). New member 'partial_resultset'
173 signals that the search was partial (hit count is lower or equal than
174 real hit count). For Z39.50, the information is stored in resultSetStatus
175 member of SearchResponse APDU. For SRU, the information is signalled
176 via SRU diagnostic 59: "Result set created with valid partial results
179 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
181 --- 2.1.46 2007/01/13
183 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
185 Added ZOOM_connection_peek_event.
187 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
188 the following new functions:
189 ZOOM_event_nonblock, ZOOM_connection_process,
190 ZOOM_connection_get_{socket,mask,timeout},
191 ZOOM_connection_fire_event_{timeout,socket}.
192 The existing blocking event handler, ZOOM_event, is a wrapper for the
193 + blocking ZOOM_event_sys_{poll,select}.
195 Implemented function ccl_xml_config which parses XML version of CCL
196 configuration (bug #798).
198 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
200 Added timings utility (yaz/timing.h)
202 --- 2.1.44 2007/01/03
204 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
207 Fixed bug #779: Rotation of apdu.log fails.
209 Fixed for character set conversions:
210 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
211 Honor G1 set in MARC-8 decoding.
213 --- 2.1.42 2006/12/17
215 Fixed bug #775: char conversion does not handle Alternative UTF-8
218 Implemented function yaz_marc_read_line which parses MARC line format
219 records. There is a wealth of formats out there. So far, this function
220 reads line records produced by yaz_marc_write_line.
222 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
223 more generic and easier to remember(!) options: -i format and -o format
224 which specifies input format and output format respectively - where
225 format is one of "marc", "marcxml", "line", "marcxchange".
227 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
228 does not print anything except warnings for records.
230 For yaz-marcdump, added support for MARC split into files (-s) with a given
233 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
234 spec, at http://www.loc.gov/standards/sru/record-update/
235 This has changed the binary layout of the following structs:
236 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
237 bend_update_rr . Patch by Ko van der Sloot.
239 Added GFS utility function bend_assoc_is_alive which returns 1 if
240 association is still alive (client is connected); 0 otherwise (client
241 closed connection). This allows busy servers to stop working for
244 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
245 been a separate piece of software. This version of ziffy has been modified
246 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
248 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
250 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
251 Client code may now interrogate options such as "init_opt_sort" to
252 find out whether the server claims to support various options.
254 --- 2.1.40 2006/11/27
256 Added utilities yaz_{set,get}_esn to set/get element set name from
259 Removed the build of libyazthread.la. The libyaz.so is the threaded version
260 of YAZ and has been so since YAZ 2.1.10.
262 Implemented ZOOM_record_error which returns error information for
263 record (surrogate diagnostic).
265 --- 2.1.38 2006/10/31
267 Updates for SRU Update by Ko van der Sloot:
268 1. Changed name from "operation" to "action"
269 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
270 versions in the code, marked as 'backward compatible'.
271 3. Added diagnostics for SRU Update.
273 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
275 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
277 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
279 For GFS, fixed problem with SRU diagnostic 'First record position out of
280 range' being issued for 0 hits.
282 zoomtst10 part of Windows Build.
284 --- 2.1.36 2006/10/13
286 Implemented yaz_filepath_comp which splits a path into file path
287 components (required by Zebra 2.0.3+).
289 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
290 BSD inspired license until now so this should not have any real impact on
291 anybody. See http://www.opensource.org/licenses/bsd-license.php
293 Fixed bug #687: Missing log lines.
295 Fixed bug #678: CQL to PQF translation does not preserve double-quote
298 Fixed bug #689: SRU diagnostics to be added.
300 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
301 whether a connection is idle (no more work do do).
303 --- 2.1.34 2006/10/04
305 Change type of optval from long to int for invocation of setsockopt with
306 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
308 Added support for specifying the max log file size for the Generic
309 Frontend Server. The size is given with option -r.
311 --- 2.1.32 2006/09/21
313 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
315 --- 2.1.30 2006/09/17
317 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
320 Fixed bug in Generic Frontend Server that could cause a server to stop
321 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
323 For the generic frontend server, the maximum record size is used as maximum
324 size of incoming packages (SRU + Z39.50). The value until was previously
325 only used in Z39.50 Init negotiation and, later, in a session controlled
326 sizes of records returned. This is controlled using -k option. It can be
327 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
329 --- 2.1.28 2006/09/04
331 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
334 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
336 New option for yaz-marcdump -lpos=value which allows setting a portion
337 of MARC header to a certain value.
339 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
341 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
342 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
344 --- 2.1.26 2006/08/15
346 Fixed problem with SRU mode type (soap, get, post) for yaz-client
349 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
351 --- 2.1.24 2006/08/08
353 Fixed MARC ISO2709 encoding routines to deal with character set
356 Minor changes to GFS logging. Database included in search request log
359 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
360 cached/multiple records.
362 Shared libraries are built by default on Unix+configure.
364 Changed cql2pqf transformation to use a different evaluation order. The
365 new order is: always, relation, structure, position, truncation, index
366 and relationModifier. Old order was: always, relation, relationModifier,
367 structure, index, position, truncation. Note that the the latter ones
368 override former ones for identical attributes.. The new scheme means that
369 it is possible to override any existing attribute with a relationModifier.
370 And also that it is possible to override everything for the index rule
371 (except the ones listed in relationModifier). No order is perfect but this
372 one, we believe, covers more real cases.. The "always" should have been
373 called "default", since the attributes there can be overridden with all
376 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
377 compilation phase, but also for yaz-config --cflags output. This allows
378 us to have public headers with Libxml2 stuff in them . It should also,
379 eventually, make Libxml2 checks redundant in packages using YAZ, such
382 --- 2.1.22 2006/06/15
384 Changed SRU update structure bend_update_rr so that SRU diagnostics are
385 stored in uri, message and details.. Previously diagnostics were stored
386 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
387 compatibility.. but he's probably the only one affected, so.
389 Added support for CCL, compiled on the client side, in ZOOM-C. This
390 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
391 input; the resulting query objects can be used for for searching with
392 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
394 YAZ' configure searches for OpenSSL by default.
396 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
397 SL_CTX_use_certificate_file. See
398 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
399 for more info. Thanks to Ko van der Sloot.
401 --- 2.1.20 2006/06/02
403 Bug #600: SRU GET, POST support for yaz-client. Introduced
404 command 'sru' which selects method SOAP/GET/POST.
406 Allow missingValueAction to be specified for the sortspec string -
407 function yaz_sort_spec. By default, the missing value action is null.
408 Use ! to specify "abort". Use = followed by stringvalue to specify default
411 Ensured that Present-handler (if defined) is called in GFS before any call to
412 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
413 searchRetrieve requests.
415 Documentation for YAZ is now based on the Docbook XML/XSLT using
416 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
417 is no longer depending on jade/openjade or docbook-to-man scripts.
418 PDF is no longer part of the distribution - but can optionally be
419 made using DSSSL/jadetex or FOP.
421 Added retrieval handling support in Generic Frontend Server to support
422 conversion between MARC/XML as well as XSLTtransforms. See
423 etc/yazgfs.xml for an example.
425 Added Authentication support to Generic Frontend Server in SRU
426 mode. Authentication using HTTP Basic is supported, as is the use
427 of 'x-username' and 'x-password' parameters in the request itself.
429 Added support for a new character set MARC8s identical to MARC8 except
430 that it converts combined characters to single Unicode characters in the
431 Latin-1 range (when possible).
433 --- 2.1.18 2006/04/24
435 ASN.1 compiler 0.4: generates brief Doxygen file header for
436 generated .h/.c files.
438 Utility yaz_iconv now supports conversion to MARC-8.
440 New facilities for the MARC module. The reading - and writing of
441 content are separate methods for the yaz_marc_t handle. The following
442 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
443 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
444 format). Write functions have prefix yaz_marc_write_.. The existing
445 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
446 available. Removed support for OAI-MARC and simplexml (not the
447 simplexml from PHP5).
449 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
450 to be returned for this connection.
452 --- 2.1.16 2006/03/31
454 Allow multiple languages and charsets to be specified with
455 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
456 negcharset iso-8859-1,utf-8
458 Translation of proximity nodes from CQL into PQF now works.
460 Moved to automake 1.8, 1.9.
462 Added function yaz_log_set_handler which allows a log handler to be
463 installed. This handler will be called for all log messages. Output
464 to file is also produced; but that can be disabled by passing NULL
465 fname to yaz_log_init_file.
467 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
469 For SRW (including GFS), accept application/soap+xml as content-type
472 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
473 produces NO stylesheet reference even if a default stylesheet is specified
476 --- 2.1.14 2006/03/14
478 Updated Windows package to include yazd.dll + yazd.lib for the
479 Development component.
481 If the environment variable YAZ_LOG is set, then it is used as a
482 string indicating the default level of logging to use if not
483 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
484 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
485 used as before. So, for example, to omit warnings from YAZ logging,
488 cql_transform() now map structure and other attributes before indexes,
489 so that index-specific structures and other attributes can override
490 defaults. So now a combination of mapping specifications such as:
492 index.dc.date = 1=date-modified 4=5
493 does the right thing.
495 cql_transform() now also respects the "always" mapping specification,
496 which establishes an initial set of attributes to be used for all
497 terms except where overridden by more specific attributes associated
498 with the index, relation or modifier.
500 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
501 which mode to use; one of "post", "get" or "soap" (SRW, default).
503 Fixes for yaz_iconv routines: changed trie-based character set conversions
504 to use only non-negative values for bit fields due to Sun's C compiler not
505 supporting negative values.
507 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
508 sequences where not read correctly. Fix by Rustam Usmanov.
510 Updated win/makefile to use options, settings which makes things
511 compile with VS C 2005.
513 --- 2.1.12 2006/02/01
515 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
517 In ZOOM socket code, use select instead of poll on MacOSX.
519 ZOOM-C now support client-side compilation of CQL into RPN that is
520 sent to the server, enabling CQL to be used against all Z39.50
521 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
522 ZOOM_query object, and submit it using ZOOM_connection_search().
523 The CQL-to-RPN translation uses a configuration file, the name of
524 which must be specified in the Connection's "cqlfile" option.
526 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
527 function, which takes as its start-term parameter a ZOOM_query object
528 (which may have had either CQL or RPN set into it).
531 --- 2.1.10 2005/11/29
533 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
534 GFS to support this as well. Backend handler, bend_srw_update, does the
535 update work. Code contributed by Ko van der Sloot.
537 Allow retrieval of Search Result-1 information in ZOOM by the use of
538 options that are attached to a result set. ZOOM documentation updated
541 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
542 UTF-8 conversion. Patch by Raj Patel.
544 Added option -m to GFS to control formatting of timestamps in log file.
546 Added 'exit' as synonym for 'quit' in yaz-client
548 Added support for specifying SRW resultSetId + resultSetIdleTime in a
549 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
550 for the new members. Patch by Ko van der Sloot.
552 Added support for SRU POST. It is supported for content-type
553 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
555 Do not build the separate Multi-threaded (MT) library libyazthread.la.
556 Instead make the library libyaz.la multi-threaded. Threading as a whole
557 can still be disabled by configure option --disable-threads. Previosly,
558 with older GLIBCs there were problems with MT libs under Apache. This
559 has now been fixed a long time ago.
561 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
564 CQL module modified to be case insensitive for relations/indexes/operations.
566 Fixed bug in CQL transform code: incorrect value relationModifieder
569 Added 'show all' command for yaz-client which retrieves all results
572 Added new yaz-client, xmles, which takes a (private) OID and
573 a document to be sent as an extended service request.
575 Describe new yaz-client commands wait_response and set_auto_wait.
577 Increase TCP/IP listener backlog from 3 (which I am guessing was
578 copied from the SunOS manual entry way back when) so SOMAXCONN, so
579 that the socket will queue as many incoming connections as it's able
580 to handle ongoing connections. In other words, it will never now
581 refuse a connection that it would be able to handle merely because
582 it's not got around to accepting() enough of the pending connections
583 yet. This is the behaviour anyway under Linux, where the listen()
584 argument is ignored; but not under BSD and on systems such as
585 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
586 YAZ-based servers should now be uniform across operating systems in
589 yaz-marcdump uses 64-bit file access on some systems. This is enabled
590 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
591 This allows yaz-marcdump to read large MARC batches (>2 GB).
593 Modified all YAZ source files - except the source which is auto-generated
594 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
597 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
598 corresponding to the existing *_setl() function. These allow option
599 values containing arbitrary valuues.
601 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
602 ZOOM_resultset_sort() in new applications. Its behaviour is identical
603 except that it returns an indicator of whether or not the sort
604 criterion was accepted (0 for OK, -1 for invalid).
608 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
609 MARC output rather than returning "new" buffer.
611 yaz-client warns about unknown init options.
613 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
617 Added support for SRW sort in Generic Frontend Server. Patch
618 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
619 sortKeys - or NULL if none is provided.
621 Fixed bug #307: It was impossible to specify indefinite/no timeout
622 for ZOOM_event. Special timeout value -1 now means indefinite timeout
625 Added support for multiple languages and charsets to be specified in
626 ZOOM. Each charset/language is separated by a blank. If negotiation is
627 in effect in init-response, Option
628 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
629 Code based on patch by Vasiliy Osadchuk.
631 Fixed bug #306: infinite recursion that occurred when calling
632 yaz_log_level_init as the first call (before other log level or
635 Fixed bug in scan handling in front end server: if preferred-Position-In-
636 Response was non-present, a NULL pointer referece was performed.
640 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
641 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
642 now defined for all those error codes. So instead of putting 109 in
643 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
644 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
646 Modified the yaz-marcdump utility to skip garbage bytes between MARC
649 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
651 Program yaz-client now exits and produces an error message if multiple
652 Z39.50 servers are specified on the command line (none or one allowed
655 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
660 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
662 Fixed bug #272: Preserve spacing for CCL terms.
666 Added support for virtual hosts and multiple backend servers for
667 the YAZ frontend server. The configution is XML based and
668 support specificition of CQL to RPN mappings and explain information.
669 See section "Virtual Hosts" in the YAZ manual.
671 Extended OPAC display utility. OPAC display utility renders
672 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
673 to supplement yaz_marc_decode_wrbuf.
675 Fixed a bug in MARC decoder that could caused it to crash for some
676 invalid MARC records. More diagnostics and warnings where added in
677 XML output (warnings, etc are stored in comments).
679 --- 2.0.34 2005/02/08
681 Fixes for UNIX domain sockets. Bug #261.
683 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
685 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
686 Added yaz_marc_subfield_str which defines subfield lead string which is
687 used in YAZ_MARC_LINE format. Default string is blank+$. Added
688 yaz_marc_endline_str which defines end of fields string used in
689 YAZ_MARC_LINE format. Default string is newline.
691 Experimental support for MarcXChange. This format can be produced
692 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
693 http://www.bs.dk/standards/MarcXchange.xsd
695 Added yaz-client commands scansize that sets maximum number of
696 entries to be returned by scan.
698 --- 2.0.32 2005/01/11
700 Added support for SRW scan in yaz-client and Generic Frontend Server.
702 * Added whereInList member to SRW Scan Term.
704 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
706 Fixed NMEM system to return aligned blocks on the smallest boundaries
707 that are suitably aligned for all possible types on the particular
708 architecture YAZ is being built for.
710 --- 2.0.30 2005/01/04
712 Fixed numerious warnings that was issued with newer versions of GCC.
714 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
715 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
718 Make YAZ Generic Frontend Server slightly faster.
720 Enhance (and reduce) logging for Generic Frontend Server.
722 Revert YAZ log system so that it flushes every write operation
723 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
725 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
726 instead of LOG_, due to name clash with syslog(3). LOG_ are still
727 present. New applications should define YAZ_USE_NEW_LOG=1 - this
728 will effectively disable old definitions.
730 --- 2.0.28 2004/11/09
732 Added yaz_log_time_format which specifies log format using
735 Added yaz_log_module_level which returns mask for a module. Value
736 is non-zero mask a if module is enabled; zero if disabled.
738 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
739 in include/yaz/cql.h.
741 Fixed bug #176: Dont throw diagnostics on empty SRU args.
743 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
745 Fixed bug #172: RPM builds does not enable SSL.
747 Doxyfile.in part of dist. Doxyfile generated by configure.
749 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
750 are given and the corresponding component does not exist.
752 Extend CCL documentation in YAZ reference. Describe r=r.
754 --- 2.0.26 2004/10/01
756 Fixed MARC->MARCXML conversion to properly deal with
757 fields, subfields, indicators having non-ASCII characters.
759 Fixed MARC->MARCXML conversion so that ASCII control characters
760 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
763 Added YAZ GFS support for conversion from Z39.50 surrogate
764 diagnostics to SRW surrogate diagnostics.
766 Bug fix: YAZ GFS did not return schema in explainResponse.
768 --- 2.0.25 2004/09/30
770 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
771 now converts recordSchema to elementSetName as well as schema URI.
773 Fixed bug in COMSTACK that prevented HTTP request packages from being
776 --- 2.0.24 2004/09/29
778 Added CCL facility r=r "range" which is similar to r=o "ordered" but
779 does not require white-space before and after the dash in a range, e.g.
780 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
783 Fixed a few AC_TRY_LINK configure tests that did not operate properly
784 due to new GCC removing "redundant" code.
786 Added yaz-client commands scanpos and scanstep that sets preferred
787 position and step-size for scan.
789 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
791 Added CCL utility ccl_qual_buf which parses one or more CCL
792 spec lines in a buffer.
794 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
795 of name and value - ignoring empty lines and comments.
797 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
799 Added odr_get_element_path which returns current element path for an
800 ODR handle. This utility is useful in error handling or user-defined
803 Added ODR_PRINT utility odr_set_stream which is is a more generic
804 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
805 to a write function and pointer to close function. The close function - if
806 non-NULL - will be called during odr_destroy.
808 Fixed bug in CCL parser where truncation char was not removed from
809 right side when truncation=both was in effect.
811 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
814 --- 2.0.23 2004/08/11
816 Fix buffer overrun in CQL parser when dealing with proximity (%).
818 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
819 to UTF-8/UCS conversion is now only based on codetables.xml.
821 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
823 --- 2.0.22 2004/08/06
825 Add support for more "commit changes" in ZOOM (uses Extended Services).
827 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
830 Yet another small fix for configure of SSL.
832 --- 2.0.21 2004/05/14
834 Fix SSL libs for configure when --with-openssl=DIR is given.
836 --- 2.0.20 2004/05/10
838 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
840 SSL comstack now uses yaz.pem certificate file on server side
841 by default. Certificate filename can be configured by calling
842 comstack function cs_set_ssl_certificate_file before cs_bind is used.
844 Fix bug regarding multiple calls to ZOOM_connection_connect.
846 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
848 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
849 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
851 ZOOM now allows inspection of X509 peer certificate for verification.
852 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
854 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
855 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
856 as "modular" but it simplifies things.
858 Added cs_get_peer_certificate to that returns peer X509 PEM.
860 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
861 NULL if SSL is unavailable.
863 Documentation about MARC decoding tools.
865 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
867 --- 2.0.19 2004/03/30
869 Rename CHANGELOG to NEWS to follow GNU style packing.
871 Fix bug with missing initialization of member in init_diagnostics.
872 This bug affects threaded version of GFS server.
874 --- 2.0.18 2004/03/20
876 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
879 Ensure zlib.dll is packed with Windows install.
881 --- 2.0.17 2004/03/17
883 Fix encoding of xsd:string to use text instead of CDATA.
885 Fix endless loop in CQL parser with unbalanced ".
887 Use a more compact way to store MARC-8 conversion tables.
889 --- 2.0.16 2004/03/16 Debian only
891 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
894 Update CQL parser to use new CQL 1.1 modifiers for booleans and
899 --- 2.0.15 2004/03/01
901 Another fix for decoding of XML packed records.
903 --- 2.0.14 2004/02/25
905 Fixes for Chunked encoding. White space not ignored after length spec.
907 Update NS and use default NS for SRW diagnostic elements.
909 --- 2.0.13 2004/02/23
911 Implement ZOOM_resultset_cache_reset which resets record cache.
913 Implement ZOOM_resultset_sort which sorts a result set.
915 Implement chunked HTTP transfer.
917 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
919 --- 2.0.12 2004/02/16
921 Added member 'schema' to bend_explain_rr structure so that backend
922 can specify explain record identifier. Defaults to Zeerex 2.0.
924 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
926 --- 2.0.11 2004/02/16
928 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
931 Added init command for yaz-client which sends "extra" init request.
933 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
934 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
936 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
938 Make ZOOM error code for "invalid query".
940 Fixed compilation for SSL which wasn't properly enabled for all platforms.
942 --- 2.0.10 2004/02/05
944 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
947 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
949 Added option -p <file> to make Generic Frontend Server to write PID file.
951 Added option -D to put Generic Frontend Server in background on its own.
953 Make ZOOM C recognize option "password". If unset, "pass" is used
954 (for backwards compatibility).
956 Fixed a bug in Generic Frontend Server that could make it crash if a
957 client sets characterSetNegotation bit, but didn't pass negotiation stuff
960 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
961 Must be issued before open, in order to be in effect.
963 --- 2.0.9-6 2004/01/12 Debian/Windows
965 Make the SRU server more picky WRT unknown params, etc.
967 Bug fix: ZOOM scan response didn't return displayTerm - when present.
969 New YAZ client command, options, that sets Z39.50 options.
971 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
972 options from a string of tokens (one token for each option bit).
974 Update SRW diagnostic code messages.
976 --- 2.0.9-5 2004/01/07 Debian/Windows
978 Handle user defined stylesheet for SRW/SRU.
980 --- 2.0.9-4 2004/01/06 Debian/Windows
982 Fix bug in decoding of Content-Length.
984 --- 2.0.9-3 2004/01/06 Debian/Windows
986 Fix a bug with decoding of XML packed records.
988 --- 2.0.9-2 2004/01/05 Debian only
990 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
992 Fix bug in SRW/SRU diagnostics decoding.
996 Fixed bug in Generic Frontend Server which could drop records exceeding
997 preferred message size. Reported and fixed by Irina Dijour.
999 Fixed calculation of package size for structured records in Generic
1000 Frontend Server. Reported and fixed by Irina Dijour.
1002 Fixed namespace for SRW/SRU diagnostics.
1004 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1006 --- 2.0.8 2003/12/22
1008 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1009 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1012 CQL changes to reflect recent changes to the specification:
1013 * Documentation talks about context sets instead of index sets.
1014 * Documentation talks about indexes instead of qualifiers.
1015 * The CQL-to-PQF transformer's configuration file now uses
1016 "index.set.name = <attributes>" instead of the old form
1017 "qualifier.set.name = <attributes>". (Both forms are still
1018 understood but the latter is deprecated.)
1019 * CQL terms with no explicit index specified are now interpreted as
1020 cql.serverChoice instead of srw.serverChoice (which of course
1021 behaves exactly the same.)
1023 --- 2.0.7 2003/12/16
1025 MARC conversion can now generate ISO2709 output in another
1026 character set. yaz-marcdump uses this facility if you invoke it
1029 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1030 functions from there can be used from C++.
1032 --- 2.0.6 2003/12/04
1034 Frontend server now transfers memory from decoded packages to stream
1037 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1038 references to show up.
1040 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1041 the ZOOM Abstract API. The older names for the same options are still
1042 also supported for the benefit of old applications.
1044 ZOOM-C supports "implementationId" and "implementationVersion" options
1045 to go along with "implementationName". These allow the user code to
1046 specify identification strings to be sent to servers.
1047 Add OID for the new ExtLite attribute set.
1049 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1050 as requested/supplid by Ere Maijala <ere@atp.fi>
1052 For generic frontend server, reverse the order of
1053 "toolkit-supplied / application-supplied" strings sent as implementationId,
1054 Name and Version. Also, remove the spaces around the slash. This brings
1055 the GFS in line with the behaviour of ZOOM-C on the client side.
1057 Add function ZOOM_scanset_display_term.
1059 yaz-client shows scan displayTerm if present.
1061 Utility yaz-iconv is now installed by default along with the man page
1064 Extend configure check for OpenSSL to use pkg-config where available (such
1067 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1068 server to specify uid/gid/mask for socket using the format
1069 unix:[user=uid,][group=gid,][umask=mask,]file=path
1070 If file= is omitted the existing format is assumed, e.g.
1072 in which case the mask is 0666 (rw for everybody).
1074 Major restructure of YAZ source. All source in libyaz is in src directory.
1075 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1076 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1078 Added man page for utility yaz-marcdump (used to be called marcdump).
1079 yaz-marcdump is installed by 'make install'.
1081 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1082 of incoming package failed.
1084 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1086 Change prototype of odr_perror: add const to message string.
1088 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1090 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1091 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1092 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1093 DNS lookup. There should not be any compatibility problems with this
1094 assuming that blocking=1 or 0 is used.
1096 Fix bad reference in UNIX comstack in function cs_addrstr.
1098 Fix for compilation on AIX.
1100 The generic front-end server (server/seshigh.c) now supports returning
1101 Init diagnostics to the client in User-information-field, in
1102 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1105 --- 2.0.4 2003/09/04
1107 Allow any CQL relation (not just all,any,exact,scr).
1109 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1110 that features the same UI.
1112 Implemented command update0 in YAZ client which is equivalent to
1113 update but uses old of Ext Update ASN.1.
1115 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1116 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1117 Previously no OID was used for this info.
1119 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1120 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1121 returns 'malformed search term' otherwise.
1123 SortResponse member resultCount now set to NULL in sort handler of
1126 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1129 Add three new utility functions for translating OIDs between various
1130 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1131 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1132 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1133 char *oid_to_dotstring(const int *oid, char *oidbuf);
1134 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1136 Reverted modifications for ES Update definition for z_IU0Update
1137 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1138 is back to YAZ 2.0.2.
1140 String value attributes for CCL parser.
1142 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1143 which their FirstSearch server returns in Init responses, sometimes
1144 carrying useful diagnostic information when Init fails. This has the
1145 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1146 "z39.50/oclcui.asn", where its definition is somewhat different from
1147 what OCLC document on their web-site, as required to interoperate with
1150 Support for anonymous authentication in yaz-client. Use the command
1153 * Fix the OID of the Index Data-local "admin" Extended Service from
1154 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1155 the 1000, which indicates a locally-defined OID, was a mistake.
1157 --- 2.0.3 2003/06/20
1159 Fix CCL directive @case handling so that it affects string match for
1160 both CCL keywords and qualifiers.
1162 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1163 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1164 Decoder has been updated with ASN.1 changes as listed in
1165 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1166 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1167 z_IUUpdate, remains unchanged.
1169 ZOOM_record_get may now return a record in a specific character set.
1170 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1171 "from" is the character set of record as returned by target. "to" is
1172 the character set to be returned. If omitted, "to" is UTF-8.
1174 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1176 New ODR utility, odr_getelement, which returns name of element for
1177 which encoding/decoding failed.
1179 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1180 in cases where a required element was omitted.
1182 Bug fix: some MARC8 sequences were not converted.
1184 New ZOOM option "step" which specifies number of records to be
1185 retrieved in one chunk. Used in conjunction with "start" and "count".
1187 SRW support for yaz-client. Use scheme http: to use it, e.g.
1190 yaz-client no longer does (un)intelligent character set conversions
1191 by default. Can be enabled with charset and marc_charset commands.
1193 xmalloc trace fix for 64-bit systems such as DEC alpha.
1195 Solaris 2.6 compile fix.
1197 New function, cql_strerror() translates SRW error codes, as returned
1198 by cql_transform_error(), into human-readable English strings. Used
1199 in yaz-client diagnostics when appropriate.
1201 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1202 converts it into a type-1 query which is sent to the server. This
1203 makes CQL available for use with all Z-servers, as opposed to the tiny
1204 minority that can handle CQL queries themselves.
1206 --- 2.0.2 2003/04/28
1208 New Debian package layout similar to the Redhat Package layout.
1210 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1211 and search result respectively.
1213 --- 2.0.1 2003/04/25
1215 Redhat package is now several packages: libyaz (runtime libraries),
1216 libyaz-devel (development and documentation, and yaz (utility programs).
1217 Package spec file by Morten Bøgeskov.
1219 New member 'schema' in struct bend_fetch_rr which the name of requested
1220 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1221 handler MAY set this to reflect the schema of the returned record.
1223 New member 'display_term' in struct scan_entry. GFS now sets member entries
1224 and allocates scan entries to be filled by user scan handler. In previous
1225 version, entries member was allocated by the scan handler. That still works,
1226 but the GFS will ignore member display_term - assuming it was NOT set by
1227 the handler. The fact that the GFS now allocates the entries both allows
1228 for new members and makes a scan handler easier to write.
1230 Fix CQL lex buffer overflow.
1232 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1233 SRU default recordPacking is string.
1235 SRU protocol support for frontend server.
1237 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1239 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1241 Added scan for the ZOOM shell (zoomsh).
1245 * String Identifers for Schemas (Amendment 5).
1246 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1247 Old definition for schema
1248 Odr_oid *schema; /* OPT */
1253 Z_InternationalString *uri;
1254 #define Z_Schema_oid 1
1255 #define Z_Schema_uri 2
1258 * resultCount parameter to Sort Response (Amendment 1).
1259 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1261 Support for SRW 1.0 over HTTP. This is an optional feature and
1262 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1265 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1266 on the same port. SRW SearchRetrieveRequests are mapped
1267 to bend_init,bend_search,bend_fetch,bend_close.
1269 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1271 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1272 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1274 ZOOM connections are SRW based if schem http is used for hostname
1275 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1276 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1278 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1279 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1280 distance=n, order=true/false, relation=le, prox unit=word. If
1281 n is omitted, distance 1 is used.
1283 Fixed problem with C compiler include path in wrong order.
1285 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1286 on Solaris. Patch from Ko van der Sloot.
1288 New MARC decode API. All new functions operate on a yaz_marc_t
1289 handle. The most important new functions are: yaz_marc_create,
1290 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1291 decode and destroy respectively. Decoder can produce formats
1292 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1293 include/yaz/marcdisp.h.
1295 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1296 to UTF-8, UCS-32, wchar_t or Latin-1.
1298 * Prototypes for yaz_iconv_-functions moved to separate header
1299 include/yaz/yaz-iconv.h.
1301 Make a few private functions 'static' in unix.c. This prevents
1302 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1304 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1305 are set when Init Response is received.
1307 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1308 but returns diagnostic set as well.
1310 New function yaz_strerror which is a portable wrapper for
1311 strerror/strerror_r/GetLastMessage.
1313 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1314 is returned for MARC. If type is "oai", then OAI MARC is returned.
1316 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1319 --- 1.9.2 2002/11/26
1321 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1323 Fix bad race conditions on SIGTERM and terminate gracefully in
1326 Move retrieval (data1) module to Zebra since nobody seems to be
1329 Add GRS-1 render for ZOOM using same format as yaz-client.
1331 --- 1.9.1 2002/10/05
1333 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1335 Fix broken ESpec handling in data1 module.
1337 SGML reader parses comments and makes them part of the data1 tree.
1339 Added several type casts so that YAZ compiles as C++ code.
1341 ZOOM didn't handle PDU encoding failures properly.
1343 Added more Bib-1 diagnostics (approved extensions).
1345 GNU configure: better check for iconv.
1347 More portable use of accept, getpeername. Check for socklen_t. Use
1348 int/size_t if socklen_t is not defined.
1352 PQF parser rejects bad queries - including those with extra
1353 characters in them. PQF parser used to silently ignore that.
1354 Cleaner API for PQF added, which allows you to get detailed
1355 error information for bad queries (see yaz/pquery.h).
1357 Fixed bug in ZOOM_record_get for type "database".
1359 Implemented mini iconv library supporting conversions between
1360 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1362 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1364 --- 1.8.9 2002/08/20
1366 Fixed ZOOM C record cache so that preferredRecordSyntax and
1367 elementSetName is used to check for already fetched records.
1369 --- 1.8.8 2002/08/02
1371 Added three members in bend_initrequest structure to facilitate
1372 character set negotiation.
1374 Fixed a bug in frontend server that could cause indefinite
1375 loops under rare conditions.
1377 Revised character set utilities (charneg.h) so that encoding
1378 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1380 For PQF, directive @term <type> sets term type for Scan/Search.
1381 Here <type> is general, string, numeric, null. The term type
1382 is inherited - just like @attr.
1384 New call odr_set_charset that sets character set conversion for
1385 international-strings on a ODR stream. Prototype is:
1386 int odr_set_charset(ODR o, const char *to, const char *from);
1387 The InternationalString is still represented as C string in YAZ
1388 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1389 won't). On the protocol level, you can use any encoding.
1391 Support for UNIX sockets in ZOOM.
1393 Solaris recv sometimes returns errno == ENOENT. It is treated as
1394 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1396 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1397 both client and server. Code by Morten Bøgeskov.
1399 --- 1.8.7 2002/05/22
1401 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1402 that they can be used directly from Visual Basic. You must recompile
1403 your windows APP if you're using ZOOM.
1405 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1406 Commands "lang" and "charset" sets language and character set respectively.
1407 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1408 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1410 Attributes from multiple CCL fields may be OR'ed rather than merged
1411 using directive "@field or". Fields are still merged by default -
1412 equivalent to "@field merge".
1414 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1417 Fixed bug in zget for parameter ExtendedServicesResponse.
1421 --- 1.8.6 2002/03/25
1423 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1425 Client displays USR.1:SearchResult-1 (hits per term).
1427 Additional Search Info for search in Generic Frontend Server.
1429 Fixed CCL parsing of "field=s".
1431 WIN32 installer - using the excellent NSIS software from nullsoft.
1433 Fixed CCL parsing of "field = - <number>".
1435 Added function yaz_marc_decode that decodes MARC for line mode
1436 display or XML (similar to that used by JZKit).
1438 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1439 Z39.50. But ISO/ILL was, however.
1441 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1442 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1444 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1445 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1447 --- 1.8.5 2002/02/03
1449 New YAZ client features: Command completion and new commands:
1450 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1451 Code provided by Jacob Poulsen.
1453 New call oid_trav, that visits all registered OIDs via callback.
1455 Function ZOOM_record_get now returns const char pointer rather than
1456 void pointer. It saves a lot of type casts.
1458 For YAZ client, command "auth" now allows you to set authentication
1459 in IdPass style. It is enabled when three tokens are given - order
1460 is user, group and password.
1462 Fix memory leaks in MARC record handling for ZOOM.
1464 New option for YAZ client, -k <kilobytes> that sets
1465 maximum record size. Similar to -k option for generic frontend
1466 server and yaz-ztest.
1468 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1470 Prefix query parser reports "fail" when bad attribute set is given.
1472 Fix in MARC decoder. Proximity logging. Fix for attribute set
1473 in scan handler for server. Patches by Shigeru Ishida.
1475 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1478 Configure option --with-openssl=<dir> now works when a directory is
1479 specified. Patch provided by Morten Bøgeskov.
1481 New option for YAZ client, -u <auth>, that sets authentication.
1483 ZOOM fix: error information was sometimes "missing", since error
1484 was cleared/reset too when it shouldn't.
1486 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1488 --- 1.8.4 2002/01/04
1490 Scan for ZOOM API. New object ZOOM_scanset. New functions
1491 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1492 ZOOM_scanset_destroy.
1494 New ZOOM function, ZOOM_connection_last_event, that returns type
1495 of last event (such as "receive data", "send data", "apdu received",
1498 New ZOOM option, schema, that specifies schema for retrieval.
1500 New CCL feature. Qualifiers can be aliases for one or more
1501 other qualifiers (if more than one is given, OR is used).
1503 ZOOM uses named result sets if target supports it.
1505 Two new YAZ client commands: . (dot, which sources a script of YAZ
1506 client commands), and ! (to execute shell command.). Implemented
1509 Working on Debian packages.
1511 --- 1.8.3 2001/11/19
1513 YAZ client enables named result sets only if target supports it.
1515 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1517 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1518 with key="host" to get same result.
1520 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1521 Function Z3950_resultset_record(s) returns references to records
1522 "owned" by resultset. To become owner use Z3950_record_clone.
1524 Function z_ext_record handles Extended Services. Thanks to
1527 --- 1.8.2 2001/11/12
1529 CCL Parser fix: ignore token comma when dealing with and-lists.
1531 Documentation updates for COMSTACK.
1533 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1534 Changed prototype Z3950_records. For some functions, int parameters
1535 were changed to size_t.
1537 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1540 New MARC decode/display function, marc_display_exl, which properly rejects
1541 non-ISO2709 records. YAZ client uses it.
1543 --- 1.8.1 2001/10/29
1545 Fix bug: local attribute set wasn't set correctly in PQF strings.
1549 * Old Z39.50 codecs no longer supported.
1551 Added ZOOM C binding. See http://zoom.z3950.org/
1553 Renamed states for COMSTACKs to avoid confusion with events.
1555 Implemented cs_look and proper cs_rcvconnect.
1557 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1559 Configure detects POSIX threads on OpenBSD.
1561 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1562 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1564 When error is returned from present handler, non-surrogate diagnostic
1565 is returned in present response (and fetch handler is no longer called).
1567 * Minor adjustments to pquery parser (PQF). Token characters may be
1568 escaped by using backslash (C-style).
1570 PQF parser allows string attribute values to be specified. For @attr,
1571 non-numeric characters after the equal-sign are treated as strings
1572 (e.g. @attr 9=title).
1574 CCL trunction character may be defined (@truncation in file)
1576 * function zget_ExtendedServicesRequest sets waitAction to
1577 waitIfPossible (was wait).
1579 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1582 CCL operator names may be set in field definition files (CCL_bibset).
1583 See ccl/bib1 for an example.
1585 Fixes in ASN.1 compiler for C++ compatibility.
1587 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1588 and "op_or" to avoid conflict with C++.
1590 Fixed problem with GNU readline detection on Redhat 7.0.
1592 Added step-size for Scan backend handler.
1594 Fixed bug that made the frontend server crash when no attribute
1595 set was specified for scan.
1597 Front-end server automatically switches to original working directory
1598 when installed as an NT service. Previously -w had to be specified to
1601 Added extended attributes for retrieval module (data1), so that data1
1602 records carry d1_readXML/SGML attributes. d1_read also supports
1603 null-data rules ( <tag/>)
1605 On UNIX when POSIX threads are available, a separate library libyazthread
1606 is created. Programmers should link with that library and the yaz library
1607 when using threads. The reason for the split was that some applications
1608 on Linux, such as Apache, doesn't work well when using shared objects that
1611 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1612 (or any frontend server) in SSL mode by specifying ssl: followed by
1613 address. Only tested on UNIX.
1615 Added feature for CCL module. Virtual structure s=al or s=ol generates
1616 and-list and or-list respectively instead of phrase search.
1620 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1621 log_mask_str. This was done to avoid name conflicts with other libraries
1622 (such as other PHP extensions).
1624 Added raw OID member for preferred record syntax (request_format_raw)
1625 and returned record syntax (output_format_raw) for backend fetch method.
1627 Config file yaz-config now accepts options so that it returns specific
1628 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1630 Shared library support for UNIX using GNU libtool.
1632 * Modified backend interface. Request/Response struct's replaced by
1633 one read/write C struct. For example bend_fetchrequest and
1634 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1635 Every handler - even search has to be registered in bend_init
1636 handler. This means that the YAZ library no longer refers to
1637 external functions and it makes it possible to make the whole
1638 thing a single DLL/SO.
1640 Added Segment handler for backend server.
1642 Added Zmbol/Zebra administrative functions to YAZ client.
1644 Threaded frontend server on UNIX (when POSIX Threads are available).
1645 Starting the server with option -T enables multi-threading.
1649 Added configure option --enable-comp/disable-comp to control use
1650 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1651 located in sub directory asn.
1653 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1654 in ${exec_prefix}/bin along with the other programs yaz-client and
1657 GNU automake used to maintain makefiles.
1659 Added several OID's.
1661 Changed retrieval module so that we can load records with no abstract
1662 syntax defined. Tagpaths in these records are fully composed of string
1665 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1669 On UNIX, the generated makefile now supports a proper 'make install'.
1670 The prefix can be set via GNU configure to set the install location
1671 (default is /usr/local).
1673 * YAZ programs client and ztest were renamed to yaz-client and
1674 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1675 locations, such as /usr/bin,/usr/local/bin,etc.
1677 * YAZ Header files were moved from include to include/yaz. YAZ Header
1678 files are referred to as include <yaz/log.h> rather than <log.h>.
1679 The YAZ include path (-I ..) is therefore the same as before. Programmers
1680 should update their #include statements or use -Ipath/include/yaz
1681 instead. The main motivation for doing this change is that YAZ header files
1682 can be installed in "standard" locations /usr/include,/usr/local/include
1683 without introducing conflicts, since ALL YAZ header files are stored
1684 in subdirectory yaz (under /usr/include for example).
1686 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1687 rather than project/workspace files. We switched because project files
1688 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1691 Changed name of logging function, logf, to yaz_log, to prevent name
1692 clash with some math-log functions. The YAZ header log.h defines logf
1693 to yaz_log (#define) so there should be no incompatibilities by this
1696 Added bend_start/bend_stop handlers for server. These handler are
1697 called on start/stop of server. For windows they are called whenever
1698 a service is started/stopped.
1700 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1701 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1702 in util/yc.tcl. The auto-generated C code structures are, in a few
1703 cases, incompatible with the old decoders. There are differences in the
1704 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1705 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1706 The preprocessor variable ASN_COMPILED is defined when the compiled
1707 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1708 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1709 wish to use the old encoders/decoders you can specify --disable-yc
1712 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1713 version so that it supports both new - and old version of DB Update
1715 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1716 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1717 change. The name parameter can be set to 0 in which no name is specified
1718 for the construction. The macros odr_implicit and odr_explicit sets name
1719 parameter to zero for the construction involved. New macros
1720 odr_implicit_tag and odr_explicit_tag are similar to the others,
1721 except that a name parameter is added. For programmers' that don't use
1722 ODR they probably only need to change the call to z_APDU and z_External.
1724 Added access control facility by interfacing the TCP wrapper library.
1725 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1726 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1727 name of the daemon and enables the access control as specified in
1728 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1730 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1731 den Dool <H.M.vdnDool@kub.nl>.
1733 Added reference ID parameter to most functions in server API - refer
1734 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1736 Changed name of ccl library to libccl.a (was ccl.a).
1738 Fixed bug in decoder for Explain (Category TargetInfo).
1740 Added support for GNU readline in client. Thanks to Jacob Poulsen
1741 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1743 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1744 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1745 IMPLEMENTATION! This change was made to the development version before
1746 the ZIG decided to retract the amendment. If any users MUST be
1747 compatible with the original Update definition, PLEASE CONTACT US, and
1748 we will include a separate definition corresponding to the old Update
1749 ES. Note that because of the change to the ASN.1 of the
1750 TaskPackageRecordStructure we cannot define a single structure that
1751 will support both versions.
1753 * Added const modifier to buffer parameter for some ODR/BER encoding
1754 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1755 completeWAIS, odr_dumpBER.
1757 Fixed bug in client.c which caused a crash when a scanResponse didn't
1758 contain positionOfTerm.
1760 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1761 * will cause an error in a client if a non-YAZ target sends both a
1762 * list of Scan entries and non-surrogate diagnostics.
1764 Retrieval module enhancements. Tag sets may be typed in the reference
1765 to it. From the .abs-file the "tagset" directive takes a third optional
1766 integer type for the tag set referenced. From a .tag-file the "include"
1767 directive takes a third optional type as well. The old "type" directive
1768 in the tag set itself is still recognized but acts as the default type
1771 Backend interface change. Individual Scan terms returned from bend_scan
1772 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1773 in include/backend.h.
1775 Retrieval module enhancements. Multiple tag sets and attribute sets may
1776 be specified in abstract syntax specs. Revised the error/warning for
1777 logging messages reported by the retrieval module when reading the
1780 Object Identifier system (oid_..) changed. The API is backwards
1781 compatible but the oid-routines now allocates new OID's when needed.
1782 Raw OID's may be specified in oid_getvalbyname.
1784 YAZ now uses GNU configure to generate Makefile(s).
1786 * Minor changes in some of the member names of DeleteResultSetRequest and
1787 DeleteResultSetResponse. See include/proto.h.
1789 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1790 and added member 'languages' in TargetInfo (which was missing).
1792 Changed the way attribute sets are handled in the retrieval
1793 module. These are now cached, just like the abstract syntaxes
1796 Changed YAZ so that it links with compiled ASN.1.
1798 Added Explain-schema definitions and mapping routines. The following
1799 Explain categories have been implemented: AttributeDetails,
1800 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1802 Fixed minor bug in Windows version of Server Library.
1804 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1806 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1808 Added EXTERNAL: UNIverse Resource Report (non-standard).
1810 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1811 ENUMERATED and SET OF.
1813 * Added 'const' to some of the char pointer arguments for the
1814 functions, data1_read_node, data1_getelementbytagname,
1815 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1818 Fixed bug in data1_insert_taggeddata - the last_child member of
1819 parent wasn't initialised.
1821 * Changed data1_read_record and data1_read_node so that the supplied
1822 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1823 doesn't refer to any parts of the "SGML"-buffer.
1825 Fixed bug in server library (Windows version of statserv_remove).
1827 * Changed code so that it compiles as C++. The type definition
1828 of Odr_fun which is a member of Odr_arm was changed. The result is,
1829 that an explicit typecast is needed for the fun pointer when
1830 using Odr_arm - as in:
1831 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1833 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1835 Implemented the new structured date and time definition as approved
1836 by the ZIG. Added schemaId element to the specificTag in Espec-1
1837 (also approved at the last ZIG). Thanks to RVDM.
1839 Added some Object identifiers (RVDM).
1841 Changed the Update Extended Service (RVDM).
1843 Added command "refid" to client which specifies referenceId for
1844 the following requests.
1846 Implemented extended service handling for server. See ztest.c
1847 for an example as well as backend.h. New handlers are registerd
1848 in the Init handler.
1850 * Changed interface for sort in server.
1852 Added new members to statserv_options_block. It allows a server
1853 to read options from another source than just the command line. Thanks
1854 to Charles Woodfield.
1856 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1857 renamed to zboolean. Some C++ compilers complained about the name.
1859 Minor changes to gils.abs. Added index 's' (sort) on title
1860 and date/time-last-modified.
1862 --- 1.4pl2 1998/1/30
1864 Fixed bug in server library regarding inetd mode (-i). This bug
1865 was introduced by release 1.4.
1867 --- 1.4pl1 1998/1/29
1869 Added sort facility in client and backend server interface.
1871 Fixed problem with dependencies in Makefile(s).
1873 Fixed bugs for encoders/decoders of extended services and
1876 Implemented sub-tree feature for schemas. Sub-trees are
1877 referenced in *.abs-files. See explain.abs for an example
1878 of the use of this feature.
1880 Modified bib1.att; local attributes for ANY didn't include
1881 ANY itself (only affects use of the retrieval module).
1883 Fixed bug in plain SGML reader in function data1_read_node:
1884 tags with prefix "var" was incorrectly interpreted as variants.
1886 Added feature "sub-schemas" to enable references to - and definitions
1887 of - group of elements.
1889 * Removed member parent from type data1_element (in data1.h).
1891 Implemented function odr_nullval() that returns the value of
1894 * Removed member num_children from data1_node (in data1.h).
1896 Made NT service interface part of the server library. The
1897 function statserv_main uses the NT service when required and
1898 calls the statserv_start / statserv_close routines.
1900 Routine zget_SearchRequest and zget_PresentRequest fills
1901 resultSetName/Id member with "default" instead of "Default".
1903 Fixed memory leak in server. Request queue member wasn't freed.
1905 Fixed nmem_exit so that memory is freed.
1909 Revised the CCL parser utility to be thread safe.
1911 Added function, oid_ent_to_oid, to replace the function
1912 oid_getoidbyent, which is not thread safe.
1914 * Added nmem_init and nmem_exit to initialize and release
1915 NMEM resources. Function nmem_init should be called once in the
1916 initial thread before NMEM/ODR is used. statserv.c and client.c
1917 have been changed accordingly. The change was necessary to make
1918 NMEM thread safe. The NMEM memory pool is shared amongst threads
1919 in a process. Unix-based applications will still work fine without
1922 Added NT Services interface for the the Z39.50 (statserv) Server.
1923 Refer to the ztest.c source on the usage.
1925 Windows 95/NT port using MSVC5.0. Project files are included in the
1928 * Defined new 'global' handle for the retrieval (data1) system. The
1929 new handled, data1_handle, describes the state of the data1 system.
1930 This handle is passed as first argument to virtually all
1931 data1 related routines. The functions data1_create and data1_destroy
1932 creates and destroys a data1 handle respectively.
1934 Added ODR encode stream member to all backend request structures
1935 init, search, scan etc. This stream should be used to allocate all
1936 memory used for the response when thread safe operation is needed.
1938 Changed the comstack utility, cs_addstr, to be thread safe. The
1939 returned hostname string returned by the function is now part the
1942 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1943 function. The cs_straddr takes a COMSTACK handle as argument, so this
1944 function must be used after cs_create and before bind/connect.
1945 This function is thread safe.
1947 Moved test server to 'ztest' directory - generic server code still
1948 in 'server' directory.
1950 Made prefix query (pquery.c) utility thread safe.
1952 Added new function modifier YAZ_EXPORT to 'export' public DLL
1953 functions when using windows (see include/yconfig.h).
1955 Added definitions to the OID database (util/oid.c) (RVDM).
1957 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1959 Added call to ccl_rpn_delete in client program.
1961 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1962 release of RPN structure.
1964 Added support for C++, headers uses extern "C" for public definitions.
1965 With input from RVDM.
1967 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1968 Thanks to Ronald van der Meer (RVDM).
1970 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1972 Added support for private extensions to the OID database
1973 (oid_setprivateoids()). Thanks to RVDM.
1975 Added optional, physical ANY (key replication)
1977 Fixed null-reference problem in GRS-1 output filter.
1979 Proximity operator added to Prefix Query Format (PQF).
1981 In test client command "base" accepts multiple databases.
1983 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1987 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1989 Smallish bug-fixes in the new encoders/decoders (explain).
1991 Bug fixed in DeleteRequest.
1993 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1995 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1997 Added SOIF syntax (using private OID for now) to retrieval module and client.
1999 Added Update extended service.
2001 Added SearchResult-1 additional info structure.
2003 Added optional CCL (ISO8777) interpreter as separate module. Available
2006 --- 1.2 1996/6/10 (1st anniversary release)
2008 Added Summary record syntax. Lightly tested.
2010 Added OPAC record syntax. Untested.
2012 Added ResourceReport service encoders/decoders. Untested.
2014 Fixed bug in z_Unit - wrong tagging on unitSystem.
2016 Fixed bug in the DiagRecs decoder.
2018 Added options for max PDU size and session timeout to frontend-server.
2020 Added documentation of query-language parsers and other supporting utilities.
2022 [frontend-server] Added Attribute set to the bend_scanrequest API.
2024 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2025 surrogate diagnostics were generated.
2027 [retrieval] Allow multiple local values for attribute.
2029 [retrieval] Allow multiple attributes per element in .abs files. index type.
2031 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2033 --- 1.1pl2 1996/4/10
2035 Minor changes, mostly specific to Zebra's requirements (retrieval)
2039 Repaired bug in frontend server when running multiple listening
2040 endpoints in dynamic mode.
2042 z_External() now won't break if a known, ASN.1 value comes encapsulated
2043 in an octet-string. The value will pass through unmodified in an Odr_oct.
2045 Added a bit of code to the demo client to decode & display
2046 ASN.1-structured records represented in the octet-aligned branch of
2047 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2049 Added z_ext_getentbyref() to the ASN module. Doc updated.
2051 * Completed the SCAN definition in the ASN module. This may break SCAN
2052 code based on older YAZ-versions at compile-time. The fix is easy -
2055 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2056 under the SCAN definition. Remember to initialize this, server-people.
2058 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2059 that this does not extend to ODR and ASN.
2061 Comstack allows insertion of established socket (primarily for
2062 inetd-operation of servers). Doc updated.
2064 Front-end server can now start from the inetd in TCP mode. Doc
2067 --- 1.0pl4 1996/1/24
2071 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2072 the rank and record number.
2074 Adjustments to the frontend server.
2076 Fixed diagnostic BER dumper. It ignored the file argument.
2080 Various changes to retrieval module.
2082 Changed the union discriminators of the protocol files from enums to
2083 ints paired with #defines.
2085 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2088 *Changed operator in the RPN structure to 'roperator', again to avoid a
2091 Fixed problems in Explain decoders/encoders.
2093 --- 1.0pl2 1995/12/6
2095 Memory bug in log module fixed.
2097 --- 1.0pl1 1995/12/5
2099 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2101 Bug in Explain DatabaseInfo module fixed.
2103 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2107 The shift to v1.0 signals that we now consider the *core* functionality
2108 of YAZ reasonably stable (the core being more or less equivalent to
2109 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2110 tested (Explain not at all - though that will happen soonish).
2112 Minor changes to code to support Windows port.
2114 Various minor changes after we're getting to use GRS-1 & co. more.
2116 Added Espec-1 format.
2118 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2119 of the protocol and it cannot be selected when encoding (maps into 'string'
2120 when decoding). Needed to talk to some servers.
2122 Demo client can request simple element set names.
2124 Added Diagnostic Format encoders/decoders.
2126 Added simple Close handling to frontend server (no hooks for resource
2127 reporting yet), and demonstration client.
2129 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2131 --- 1.0b3 1995/08/24
2133 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2134 handled incorrectly when records were requested in the searchResponse. This
2135 will only affect you if you use the frontend-server.
2137 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2138 Test-client will ask for and print GRS1. Ztest will return dummy records
2141 Added Explain encoders/decoders to the service-level API. Untested.
2143 Added Extended Services: Item Order encoders and decoders to the Service-
2144 level API. Untested. We could use a recent copy of the pertinent bits
2145 of the ILL protocol to add those bits.
2147 Added diagnostic format 1 encoders/decoders to the service-level API.
2150 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2151 odr_cons.c, which causes a more correct output.
2153 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2154 was always set to 0 when no records were requested in the searchRequest.
2156 * Added better external-handling. This shouldn't harm old code that
2157 *encodes* externals. It can break code that looks for a
2158 'single-ASN1-type' representation, since those types that are known
2159 are now decoded immediately. Look at the SUTRS sample code in
2160 seshigh.c and client.c. Documentation updated.
2162 Handling of structured records in bend_fetchresponse. Length -1 marks
2163 structured record, type is deduced from format field.
2165 --- 1.0b2 1995/06/27
2166 Fairly quick maintenance release to add SUTRS support.
2168 Fixed handling of SUTRS records in the demonstration client.
2170 * Added format field to the bend_fetchrequest and bend_fetchresponce
2171 structures of the backend API (frontend server). When the record is
2172 returned, the value of the format field is mapped to an OID. The
2173 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2174 of the record. The special value VAL_NONE in the bend_request means
2175 that no specific format was requested by the client. Documentation
2176 updated accordingly. Test server (ztest) will return a fixed dummy
2177 SUTRS record if your client requests SUTRS.
2179 Documentation updated accordingly.
2181 You can now set external libraries and RANLIB support in the top-level
2185 First public release.
