1 Allow waitAction to be specified for ZOOM C based for Extended Services.
5 Fixed bug #1157: yaz-client does not read .yazclientrc from current
6 directory. yaz-client now reads commands from file given by option -f
7 if specified; then tries to read .yazclientrc in current directory.
8 Failing that, it reads .yazclientrc from user's home directory.
10 Added support for correlationInfo Note and ID for Record Update via
13 Added yaz-client command querycharset which specifies character set for
14 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
15 (termListAndStartPoint).
17 Charset ISO5428:1984 is an alias for ISO5428-1984.
19 Implemented a way to perform scan in a result set using Z39.50. This
20 is achieved by attaching the result set name in the characterInfo
21 (type InternationalString) of OtherInformation in the Scan Request PDU.
22 The result set is identified in the otherinformation by the new OID:
23 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
24 This allows for scan in result set and faceted search . Zebra did some
25 of this in the APT term using attribute type 8 and value being result
26 set. Using the OtherInformation approach for this is cleaner and easier
27 to work with in proxies and the like. This facility can be used in
28 yaz-client using new command setscan which takes a result set as first
29 argument, start position (APT) as second.
31 Changed decoding of SRU XML packed records to deal with servers that
32 have recordData with XML data with multiple root nodes. Also make
33 comparison for recordPacking case insensitive. Again, one server
34 returns "XML" where others return "xml".
36 For SRU responses allow Content-Type application/xml as well as text/xml.
40 Fixed bug in character set conversion of BER strings. Bug introduced
45 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
47 For OID class, use oid_class consistently.
49 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
52 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
53 character set for bibliographic information interchange". By Giannis Kosmas.
55 Added documentation on new OID API.
59 Changes to generic frontend server interface: added new member
60 'query_charset' for bend_initrequest structure. A backend init handler
61 should set this member to its native character set for query terms.
62 When defined, the frontend server logic will announce this character set
63 to a client if the negotiationModel bit is set by the client. All server
64 implementors are encouraged to specify this. If a backend server does not
65 specify this a warning is issued using yaz_log(YLOG_WARN,..).
67 Added CCL utility to remove terms (stop words) from resulting RPN
68 tree. This is handled by functions with prefix ccl_stop_words_ .
70 New ZOOM C option, "rpnCharset", which allows client-side conversion of
73 Clean-up the CCL API. Moved some internal structures from ccl.h to
74 private header cclp.h. Changed ccl_parser_create so that a Bibset must
75 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
76 This is replaced by ccl_parser_find_str which takes a string instead.
78 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
79 libyaz.la is the core of YAZ except the generic frontend server and
80 does not depend on POSIX threads anymore. libyaz_server.la is the
81 generic frontend server facilities and uses POSIX thread functionality
82 if available. The libyaz.la no longer depends on POSIX threads because
83 the number of global structures is limited. NMEM no longer re-uses blocks
84 between threads ; it simply free's memory immediately but allocates in
85 "large" chunks as usual. We don't expect any performance penalties
86 because of this. The yaz_log system is still using a global log_level so
87 caution must be taken when modifying it with yaz_log_init_.. +
88 yaz_log_mask_str. This, however, should not cause any trouble because
89 these functions are called during initialization of application code
90 anyway. `yaz-config --libs server` returns libs for server applications;
91 `yaz-config --libs` returns libs for non-server applications.
93 New OID database - with public definitions in oid_db.h. Removed old OID
94 database including the head oid.h and definitions such as enum oid_value
95 and struct oident. The new OID database uses the same string names as
96 before but the 'protocol' is gone. There are now only two representations
97 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
98 converts from string to OID; functions with prefix yaz_oid_to_string
99 converts the other way.
101 Change to emit_term() in CQL-to-PQF query translation: when a term has
102 the /regexp relation modifier, do not process it for leading and
103 trailing "^" and "*", which have quite different meanings in regular
106 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
107 write handlers no longer carries a 'last' parameter. This will make
108 yaz_iconv flush "less" characters. A flush is performed by call to
109 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
111 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
112 removed, because function yaz_query_to_wrbuf does the same.
114 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
115 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
117 Deprecated MARC utility functions removed.
119 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
122 Branch split: YAZ_2_1_55_branch
124 --- 2.1.54 2007/03/16
126 Fix to ZOOM-C so that transparent reconnection is properly handled on
127 connections that are in asynchronous mode.
129 Fixed compilation on OpenBSD 4.0.
131 Large strings in GRS-1 records are now properly displayed in yaz-client.
133 Added character conversion support for "advancegreek"; based on patch from
136 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
137 sequence is met. Before the error was not set so it would be unknown.
139 Adjust yaz-marcdump MARC reader so that it skips until record separator
142 --- 2.1.52 2007/03/07
144 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
145 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
146 fd_set structure used as a bitmask for the FDs to be selected on.
148 Using ACX_PTHREAD macro to check for POSIX threads.
150 Fixed have-vsnprintf check.
152 --- 2.1.50 2007/02/23
154 Fixes for configure on BSD. Bug #900.
156 Added snprintf/vsnprintf wrappers for systems that don't have
157 limits (heavens forbid).
159 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
160 created before all previous tasks were completed and removed from the
161 task queue, the new task could be removed by a mistake.
163 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
165 Implemented pass-through CQL-to-PQF conversions. Bug #861.
167 Fixed bug #832: Problem with MARC/charset in yaz-client.
169 Fixed bug #668: save command line history for yaz-client.
171 Fixed bug #830: pkg-config support.
173 --- 2.1.48 2007/01/23
175 Extended ZOOM result set options with two options that may be read by
176 a client: resultSetStatus and presentStatus with values as specified for
178 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
180 Fixed bug #827: Using SSL fails on Debian etch.
182 Fixed bug #826: Weird looking chars for set of MARC records.
184 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
185 that is treated as an ItemOrder with itemRequest being an XML document
186 external. The value of "doc" is the content.
188 Extended the GFS search facility. New member of bend_search_rr
189 'estimated_hit_count' signals that hits is known to be an estmate
190 (higher or lower than real hit count). New member 'partial_resultset'
191 signals that the search was partial (hit count is lower or equal than
192 real hit count). For Z39.50, the information is stored in resultSetStatus
193 member of SearchResponse APDU. For SRU, the information is signalled
194 via SRU diagnostic 59: "Result set created with valid partial results
197 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
199 --- 2.1.46 2007/01/13
201 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
203 Added ZOOM_connection_peek_event.
205 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
206 the following new functions:
207 ZOOM_event_nonblock, ZOOM_connection_process,
208 ZOOM_connection_get_{socket,mask,timeout},
209 ZOOM_connection_fire_event_{timeout,socket}.
210 The existing blocking event handler, ZOOM_event, is a wrapper for the
211 + blocking ZOOM_event_sys_{poll,select}.
213 Implemented function ccl_xml_config which parses XML version of CCL
214 configuration (bug #798).
216 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
218 Added timings utility (yaz/timing.h)
220 --- 2.1.44 2007/01/03
222 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
225 Fixed bug #779: Rotation of apdu.log fails.
227 Fixed for character set conversions:
228 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
229 Honor G1 set in MARC-8 decoding.
231 --- 2.1.42 2006/12/17
233 Fixed bug #775: char conversion does not handle Alternative UTF-8
236 Implemented function yaz_marc_read_line which parses MARC line format
237 records. There is a wealth of formats out there. So far, this function
238 reads line records produced by yaz_marc_write_line.
240 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
241 more generic and easier to remember(!) options: -i format and -o format
242 which specifies input format and output format respectively - where
243 format is one of "marc", "marcxml", "line", "marcxchange".
245 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
246 does not print anything except warnings for records.
248 For yaz-marcdump, added support for MARC split into files (-s) with a given
251 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
252 spec, at http://www.loc.gov/standards/sru/record-update/
253 This has changed the binary layout of the following structs:
254 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
255 bend_update_rr . Patch by Ko van der Sloot.
257 Added GFS utility function bend_assoc_is_alive which returns 1 if
258 association is still alive (client is connected); 0 otherwise (client
259 closed connection). This allows busy servers to stop working for
262 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
263 been a separate piece of software. This version of ziffy has been modified
264 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
266 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
268 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
269 Client code may now interrogate options such as "init_opt_sort" to
270 find out whether the server claims to support various options.
272 --- 2.1.40 2006/11/27
274 Added utilities yaz_{set,get}_esn to set/get element set name from
277 Removed the build of libyazthread.la. The libyaz.so is the threaded version
278 of YAZ and has been so since YAZ 2.1.10.
280 Implemented ZOOM_record_error which returns error information for
281 record (surrogate diagnostic).
283 --- 2.1.38 2006/10/31
285 Updates for SRU Update by Ko van der Sloot:
286 1. Changed name from "operation" to "action"
287 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
288 versions in the code, marked as 'backward compatible'.
289 3. Added diagnostics for SRU Update.
291 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
293 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
295 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
297 For GFS, fixed problem with SRU diagnostic 'First record position out of
298 range' being issued for 0 hits.
300 zoomtst10 part of Windows Build.
302 --- 2.1.36 2006/10/13
304 Implemented yaz_filepath_comp which splits a path into file path
305 components (required by Zebra 2.0.3+).
307 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
308 BSD inspired license until now so this should not have any real impact on
309 anybody. See http://www.opensource.org/licenses/bsd-license.php
311 Fixed bug #687: Missing log lines.
313 Fixed bug #678: CQL to PQF translation does not preserve double-quote
316 Fixed bug #689: SRU diagnostics to be added.
318 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
319 whether a connection is idle (no more work do do).
321 --- 2.1.34 2006/10/04
323 Change type of optval from long to int for invocation of setsockopt with
324 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
326 Added support for specifying the max log file size for the Generic
327 Frontend Server. The size is given with option -r.
329 --- 2.1.32 2006/09/21
331 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
333 --- 2.1.30 2006/09/17
335 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
338 Fixed bug in Generic Frontend Server that could cause a server to stop
339 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
341 For the generic frontend server, the maximum record size is used as maximum
342 size of incoming packages (SRU + Z39.50). The value until was previously
343 only used in Z39.50 Init negotiation and, later, in a session controlled
344 sizes of records returned. This is controlled using -k option. It can be
345 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
347 --- 2.1.28 2006/09/04
349 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
352 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
354 New option for yaz-marcdump -lpos=value which allows setting a portion
355 of MARC header to a certain value.
357 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
359 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
360 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
362 --- 2.1.26 2006/08/15
364 Fixed problem with SRU mode type (soap, get, post) for yaz-client
367 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
369 --- 2.1.24 2006/08/08
371 Fixed MARC ISO2709 encoding routines to deal with character set
374 Minor changes to GFS logging. Database included in search request log
377 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
378 cached/multiple records.
380 Shared libraries are built by default on Unix+configure.
382 Changed cql2pqf transformation to use a different evaluation order. The
383 new order is: always, relation, structure, position, truncation, index
384 and relationModifier. Old order was: always, relation, relationModifier,
385 structure, index, position, truncation. Note that the the latter ones
386 override former ones for identical attributes.. The new scheme means that
387 it is possible to override any existing attribute with a relationModifier.
388 And also that it is possible to override everything for the index rule
389 (except the ones listed in relationModifier). No order is perfect but this
390 one, we believe, covers more real cases.. The "always" should have been
391 called "default", since the attributes there can be overridden with all
394 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
395 compilation phase, but also for yaz-config --cflags output. This allows
396 us to have public headers with Libxml2 stuff in them . It should also,
397 eventually, make Libxml2 checks redundant in packages using YAZ, such
400 --- 2.1.22 2006/06/15
402 Changed SRU update structure bend_update_rr so that SRU diagnostics are
403 stored in uri, message and details.. Previously diagnostics were stored
404 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
405 compatibility.. but he's probably the only one affected, so.
407 Added support for CCL, compiled on the client side, in ZOOM-C. This
408 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
409 input; the resulting query objects can be used for for searching with
410 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
412 YAZ' configure searches for OpenSSL by default.
414 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
415 SL_CTX_use_certificate_file. See
416 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
417 for more info. Thanks to Ko van der Sloot.
419 --- 2.1.20 2006/06/02
421 Bug #600: SRU GET, POST support for yaz-client. Introduced
422 command 'sru' which selects method SOAP/GET/POST.
424 Allow missingValueAction to be specified for the sortspec string -
425 function yaz_sort_spec. By default, the missing value action is null.
426 Use ! to specify "abort". Use = followed by stringvalue to specify default
429 Ensured that Present-handler (if defined) is called in GFS before any call to
430 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
431 searchRetrieve requests.
433 Documentation for YAZ is now based on the Docbook XML/XSLT using
434 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
435 is no longer depending on jade/openjade or docbook-to-man scripts.
436 PDF is no longer part of the distribution - but can optionally be
437 made using DSSSL/jadetex or FOP.
439 Added retrieval handling support in Generic Frontend Server to support
440 conversion between MARC/XML as well as XSLTtransforms. See
441 etc/yazgfs.xml for an example.
443 Added Authentication support to Generic Frontend Server in SRU
444 mode. Authentication using HTTP Basic is supported, as is the use
445 of 'x-username' and 'x-password' parameters in the request itself.
447 Added support for a new character set MARC8s identical to MARC8 except
448 that it converts combined characters to single Unicode characters in the
449 Latin-1 range (when possible).
451 --- 2.1.18 2006/04/24
453 ASN.1 compiler 0.4: generates brief Doxygen file header for
454 generated .h/.c files.
456 Utility yaz_iconv now supports conversion to MARC-8.
458 New facilities for the MARC module. The reading - and writing of
459 content are separate methods for the yaz_marc_t handle. The following
460 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
461 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
462 format). Write functions have prefix yaz_marc_write_.. The existing
463 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
464 available. Removed support for OAI-MARC and simplexml (not the
465 simplexml from PHP5).
467 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
468 to be returned for this connection.
470 --- 2.1.16 2006/03/31
472 Allow multiple languages and charsets to be specified with
473 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
474 negcharset iso-8859-1,utf-8
476 Translation of proximity nodes from CQL into PQF now works.
478 Moved to automake 1.8, 1.9.
480 Added function yaz_log_set_handler which allows a log handler to be
481 installed. This handler will be called for all log messages. Output
482 to file is also produced; but that can be disabled by passing NULL
483 fname to yaz_log_init_file.
485 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
487 For SRW (including GFS), accept application/soap+xml as content-type
490 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
491 produces NO stylesheet reference even if a default stylesheet is specified
494 --- 2.1.14 2006/03/14
496 Updated Windows package to include yazd.dll + yazd.lib for the
497 Development component.
499 If the environment variable YAZ_LOG is set, then it is used as a
500 string indicating the default level of logging to use if not
501 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
502 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
503 used as before. So, for example, to omit warnings from YAZ logging,
506 cql_transform() now map structure and other attributes before indexes,
507 so that index-specific structures and other attributes can override
508 defaults. So now a combination of mapping specifications such as:
510 index.dc.date = 1=date-modified 4=5
511 does the right thing.
513 cql_transform() now also respects the "always" mapping specification,
514 which establishes an initial set of attributes to be used for all
515 terms except where overridden by more specific attributes associated
516 with the index, relation or modifier.
518 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
519 which mode to use; one of "post", "get" or "soap" (SRW, default).
521 Fixes for yaz_iconv routines: changed trie-based character set conversions
522 to use only non-negative values for bit fields due to Sun's C compiler not
523 supporting negative values.
525 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
526 sequences where not read correctly. Fix by Rustam Usmanov.
528 Updated win/makefile to use options, settings which makes things
529 compile with VS C 2005.
531 --- 2.1.12 2006/02/01
533 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
535 In ZOOM socket code, use select instead of poll on MacOSX.
537 ZOOM-C now support client-side compilation of CQL into RPN that is
538 sent to the server, enabling CQL to be used against all Z39.50
539 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
540 ZOOM_query object, and submit it using ZOOM_connection_search().
541 The CQL-to-RPN translation uses a configuration file, the name of
542 which must be specified in the Connection's "cqlfile" option.
544 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
545 function, which takes as its start-term parameter a ZOOM_query object
546 (which may have had either CQL or RPN set into it).
549 --- 2.1.10 2005/11/29
551 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
552 GFS to support this as well. Backend handler, bend_srw_update, does the
553 update work. Code contributed by Ko van der Sloot.
555 Allow retrieval of Search Result-1 information in ZOOM by the use of
556 options that are attached to a result set. ZOOM documentation updated
559 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
560 UTF-8 conversion. Patch by Raj Patel.
562 Added option -m to GFS to control formatting of timestamps in log file.
564 Added 'exit' as synonym for 'quit' in yaz-client
566 Added support for specifying SRW resultSetId + resultSetIdleTime in a
567 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
568 for the new members. Patch by Ko van der Sloot.
570 Added support for SRU POST. It is supported for content-type
571 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
573 Do not build the separate Multi-threaded (MT) library libyazthread.la.
574 Instead make the library libyaz.la multi-threaded. Threading as a whole
575 can still be disabled by configure option --disable-threads. Previosly,
576 with older GLIBCs there were problems with MT libs under Apache. This
577 has now been fixed a long time ago.
579 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
582 CQL module modified to be case insensitive for relations/indexes/operations.
584 Fixed bug in CQL transform code: incorrect value relationModifieder
587 Added 'show all' command for yaz-client which retrieves all results
590 Added new yaz-client, xmles, which takes a (private) OID and
591 a document to be sent as an extended service request.
593 Describe new yaz-client commands wait_response and set_auto_wait.
595 Increase TCP/IP listener backlog from 3 (which I am guessing was
596 copied from the SunOS manual entry way back when) so SOMAXCONN, so
597 that the socket will queue as many incoming connections as it's able
598 to handle ongoing connections. In other words, it will never now
599 refuse a connection that it would be able to handle merely because
600 it's not got around to accepting() enough of the pending connections
601 yet. This is the behaviour anyway under Linux, where the listen()
602 argument is ignored; but not under BSD and on systems such as
603 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
604 YAZ-based servers should now be uniform across operating systems in
607 yaz-marcdump uses 64-bit file access on some systems. This is enabled
608 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
609 This allows yaz-marcdump to read large MARC batches (>2 GB).
611 Modified all YAZ source files - except the source which is auto-generated
612 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
615 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
616 corresponding to the existing *_setl() function. These allow option
617 values containing arbitrary valuues.
619 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
620 ZOOM_resultset_sort() in new applications. Its behaviour is identical
621 except that it returns an indicator of whether or not the sort
622 criterion was accepted (0 for OK, -1 for invalid).
626 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
627 MARC output rather than returning "new" buffer.
629 yaz-client warns about unknown init options.
631 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
635 Added support for SRW sort in Generic Frontend Server. Patch
636 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
637 sortKeys - or NULL if none is provided.
639 Fixed bug #307: It was impossible to specify indefinite/no timeout
640 for ZOOM_event. Special timeout value -1 now means indefinite timeout
643 Added support for multiple languages and charsets to be specified in
644 ZOOM. Each charset/language is separated by a blank. If negotiation is
645 in effect in init-response, Option
646 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
647 Code based on patch by Vasiliy Osadchuk.
649 Fixed bug #306: infinite recursion that occurred when calling
650 yaz_log_level_init as the first call (before other log level or
653 Fixed bug in scan handling in front end server: if preferred-Position-In-
654 Response was non-present, a NULL pointer referece was performed.
658 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
659 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
660 now defined for all those error codes. So instead of putting 109 in
661 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
662 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
664 Modified the yaz-marcdump utility to skip garbage bytes between MARC
667 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
669 Program yaz-client now exits and produces an error message if multiple
670 Z39.50 servers are specified on the command line (none or one allowed
673 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
678 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
680 Fixed bug #272: Preserve spacing for CCL terms.
684 Added support for virtual hosts and multiple backend servers for
685 the YAZ frontend server. The configution is XML based and
686 support specificition of CQL to RPN mappings and explain information.
687 See section "Virtual Hosts" in the YAZ manual.
689 Extended OPAC display utility. OPAC display utility renders
690 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
691 to supplement yaz_marc_decode_wrbuf.
693 Fixed a bug in MARC decoder that could caused it to crash for some
694 invalid MARC records. More diagnostics and warnings where added in
695 XML output (warnings, etc are stored in comments).
697 --- 2.0.34 2005/02/08
699 Fixes for UNIX domain sockets. Bug #261.
701 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
703 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
704 Added yaz_marc_subfield_str which defines subfield lead string which is
705 used in YAZ_MARC_LINE format. Default string is blank+$. Added
706 yaz_marc_endline_str which defines end of fields string used in
707 YAZ_MARC_LINE format. Default string is newline.
709 Experimental support for MarcXChange. This format can be produced
710 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
711 http://www.bs.dk/standards/MarcXchange.xsd
713 Added yaz-client commands scansize that sets maximum number of
714 entries to be returned by scan.
716 --- 2.0.32 2005/01/11
718 Added support for SRW scan in yaz-client and Generic Frontend Server.
720 * Added whereInList member to SRW Scan Term.
722 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
724 Fixed NMEM system to return aligned blocks on the smallest boundaries
725 that are suitably aligned for all possible types on the particular
726 architecture YAZ is being built for.
728 --- 2.0.30 2005/01/04
730 Fixed numerious warnings that was issued with newer versions of GCC.
732 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
733 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
736 Make YAZ Generic Frontend Server slightly faster.
738 Enhance (and reduce) logging for Generic Frontend Server.
740 Revert YAZ log system so that it flushes every write operation
741 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
743 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
744 instead of LOG_, due to name clash with syslog(3). LOG_ are still
745 present. New applications should define YAZ_USE_NEW_LOG=1 - this
746 will effectively disable old definitions.
748 --- 2.0.28 2004/11/09
750 Added yaz_log_time_format which specifies log format using
753 Added yaz_log_module_level which returns mask for a module. Value
754 is non-zero mask a if module is enabled; zero if disabled.
756 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
757 in include/yaz/cql.h.
759 Fixed bug #176: Dont throw diagnostics on empty SRU args.
761 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
763 Fixed bug #172: RPM builds does not enable SSL.
765 Doxyfile.in part of dist. Doxyfile generated by configure.
767 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
768 are given and the corresponding component does not exist.
770 Extend CCL documentation in YAZ reference. Describe r=r.
772 --- 2.0.26 2004/10/01
774 Fixed MARC->MARCXML conversion to properly deal with
775 fields, subfields, indicators having non-ASCII characters.
777 Fixed MARC->MARCXML conversion so that ASCII control characters
778 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
781 Added YAZ GFS support for conversion from Z39.50 surrogate
782 diagnostics to SRW surrogate diagnostics.
784 Bug fix: YAZ GFS did not return schema in explainResponse.
786 --- 2.0.25 2004/09/30
788 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
789 now converts recordSchema to elementSetName as well as schema URI.
791 Fixed bug in COMSTACK that prevented HTTP request packages from being
794 --- 2.0.24 2004/09/29
796 Added CCL facility r=r "range" which is similar to r=o "ordered" but
797 does not require white-space before and after the dash in a range, e.g.
798 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
801 Fixed a few AC_TRY_LINK configure tests that did not operate properly
802 due to new GCC removing "redundant" code.
804 Added yaz-client commands scanpos and scanstep that sets preferred
805 position and step-size for scan.
807 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
809 Added CCL utility ccl_qual_buf which parses one or more CCL
810 spec lines in a buffer.
812 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
813 of name and value - ignoring empty lines and comments.
815 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
817 Added odr_get_element_path which returns current element path for an
818 ODR handle. This utility is useful in error handling or user-defined
821 Added ODR_PRINT utility odr_set_stream which is is a more generic
822 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
823 to a write function and pointer to close function. The close function - if
824 non-NULL - will be called during odr_destroy.
826 Fixed bug in CCL parser where truncation char was not removed from
827 right side when truncation=both was in effect.
829 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
832 --- 2.0.23 2004/08/11
834 Fix buffer overrun in CQL parser when dealing with proximity (%).
836 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
837 to UTF-8/UCS conversion is now only based on codetables.xml.
839 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
841 --- 2.0.22 2004/08/06
843 Add support for more "commit changes" in ZOOM (uses Extended Services).
845 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
848 Yet another small fix for configure of SSL.
850 --- 2.0.21 2004/05/14
852 Fix SSL libs for configure when --with-openssl=DIR is given.
854 --- 2.0.20 2004/05/10
856 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
858 SSL comstack now uses yaz.pem certificate file on server side
859 by default. Certificate filename can be configured by calling
860 comstack function cs_set_ssl_certificate_file before cs_bind is used.
862 Fix bug regarding multiple calls to ZOOM_connection_connect.
864 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
866 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
867 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
869 ZOOM now allows inspection of X509 peer certificate for verification.
870 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
872 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
873 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
874 as "modular" but it simplifies things.
876 Added cs_get_peer_certificate to that returns peer X509 PEM.
878 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
879 NULL if SSL is unavailable.
881 Documentation about MARC decoding tools.
883 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
885 --- 2.0.19 2004/03/30
887 Rename CHANGELOG to NEWS to follow GNU style packing.
889 Fix bug with missing initialization of member in init_diagnostics.
890 This bug affects threaded version of GFS server.
892 --- 2.0.18 2004/03/20
894 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
897 Ensure zlib.dll is packed with Windows install.
899 --- 2.0.17 2004/03/17
901 Fix encoding of xsd:string to use text instead of CDATA.
903 Fix endless loop in CQL parser with unbalanced ".
905 Use a more compact way to store MARC-8 conversion tables.
907 --- 2.0.16 2004/03/16 Debian only
909 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
912 Update CQL parser to use new CQL 1.1 modifiers for booleans and
917 --- 2.0.15 2004/03/01
919 Another fix for decoding of XML packed records.
921 --- 2.0.14 2004/02/25
923 Fixes for Chunked encoding. White space not ignored after length spec.
925 Update NS and use default NS for SRW diagnostic elements.
927 --- 2.0.13 2004/02/23
929 Implement ZOOM_resultset_cache_reset which resets record cache.
931 Implement ZOOM_resultset_sort which sorts a result set.
933 Implement chunked HTTP transfer.
935 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
937 --- 2.0.12 2004/02/16
939 Added member 'schema' to bend_explain_rr structure so that backend
940 can specify explain record identifier. Defaults to Zeerex 2.0.
942 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
944 --- 2.0.11 2004/02/16
946 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
949 Added init command for yaz-client which sends "extra" init request.
951 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
952 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
954 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
956 Make ZOOM error code for "invalid query".
958 Fixed compilation for SSL which wasn't properly enabled for all platforms.
960 --- 2.0.10 2004/02/05
962 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
965 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
967 Added option -p <file> to make Generic Frontend Server to write PID file.
969 Added option -D to put Generic Frontend Server in background on its own.
971 Make ZOOM C recognize option "password". If unset, "pass" is used
972 (for backwards compatibility).
974 Fixed a bug in Generic Frontend Server that could make it crash if a
975 client sets characterSetNegotation bit, but didn't pass negotiation stuff
978 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
979 Must be issued before open, in order to be in effect.
981 --- 2.0.9-6 2004/01/12 Debian/Windows
983 Make the SRU server more picky WRT unknown params, etc.
985 Bug fix: ZOOM scan response didn't return displayTerm - when present.
987 New YAZ client command, options, that sets Z39.50 options.
989 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
990 options from a string of tokens (one token for each option bit).
992 Update SRW diagnostic code messages.
994 --- 2.0.9-5 2004/01/07 Debian/Windows
996 Handle user defined stylesheet for SRW/SRU.
998 --- 2.0.9-4 2004/01/06 Debian/Windows
1000 Fix bug in decoding of Content-Length.
1002 --- 2.0.9-3 2004/01/06 Debian/Windows
1004 Fix a bug with decoding of XML packed records.
1006 --- 2.0.9-2 2004/01/05 Debian only
1008 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1010 Fix bug in SRW/SRU diagnostics decoding.
1012 --- 2.0.9 2004/01/05
1014 Fixed bug in Generic Frontend Server which could drop records exceeding
1015 preferred message size. Reported and fixed by Irina Dijour.
1017 Fixed calculation of package size for structured records in Generic
1018 Frontend Server. Reported and fixed by Irina Dijour.
1020 Fixed namespace for SRW/SRU diagnostics.
1022 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1024 --- 2.0.8 2003/12/22
1026 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1027 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1030 CQL changes to reflect recent changes to the specification:
1031 * Documentation talks about context sets instead of index sets.
1032 * Documentation talks about indexes instead of qualifiers.
1033 * The CQL-to-PQF transformer's configuration file now uses
1034 "index.set.name = <attributes>" instead of the old form
1035 "qualifier.set.name = <attributes>". (Both forms are still
1036 understood but the latter is deprecated.)
1037 * CQL terms with no explicit index specified are now interpreted as
1038 cql.serverChoice instead of srw.serverChoice (which of course
1039 behaves exactly the same.)
1041 --- 2.0.7 2003/12/16
1043 MARC conversion can now generate ISO2709 output in another
1044 character set. yaz-marcdump uses this facility if you invoke it
1047 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1048 functions from there can be used from C++.
1050 --- 2.0.6 2003/12/04
1052 Frontend server now transfers memory from decoded packages to stream
1055 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1056 references to show up.
1058 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1059 the ZOOM Abstract API. The older names for the same options are still
1060 also supported for the benefit of old applications.
1062 ZOOM-C supports "implementationId" and "implementationVersion" options
1063 to go along with "implementationName". These allow the user code to
1064 specify identification strings to be sent to servers.
1065 Add OID for the new ExtLite attribute set.
1067 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1068 as requested/supplid by Ere Maijala <ere@atp.fi>
1070 For generic frontend server, reverse the order of
1071 "toolkit-supplied / application-supplied" strings sent as implementationId,
1072 Name and Version. Also, remove the spaces around the slash. This brings
1073 the GFS in line with the behaviour of ZOOM-C on the client side.
1075 Add function ZOOM_scanset_display_term.
1077 yaz-client shows scan displayTerm if present.
1079 Utility yaz-iconv is now installed by default along with the man page
1082 Extend configure check for OpenSSL to use pkg-config where available (such
1085 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1086 server to specify uid/gid/mask for socket using the format
1087 unix:[user=uid,][group=gid,][umask=mask,]file=path
1088 If file= is omitted the existing format is assumed, e.g.
1090 in which case the mask is 0666 (rw for everybody).
1092 Major restructure of YAZ source. All source in libyaz is in src directory.
1093 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1094 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1096 Added man page for utility yaz-marcdump (used to be called marcdump).
1097 yaz-marcdump is installed by 'make install'.
1099 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1100 of incoming package failed.
1102 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1104 Change prototype of odr_perror: add const to message string.
1106 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1108 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1109 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1110 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1111 DNS lookup. There should not be any compatibility problems with this
1112 assuming that blocking=1 or 0 is used.
1114 Fix bad reference in UNIX comstack in function cs_addrstr.
1116 Fix for compilation on AIX.
1118 The generic front-end server (server/seshigh.c) now supports returning
1119 Init diagnostics to the client in User-information-field, in
1120 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1123 --- 2.0.4 2003/09/04
1125 Allow any CQL relation (not just all,any,exact,scr).
1127 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1128 that features the same UI.
1130 Implemented command update0 in YAZ client which is equivalent to
1131 update but uses old of Ext Update ASN.1.
1133 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1134 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1135 Previously no OID was used for this info.
1137 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1138 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1139 returns 'malformed search term' otherwise.
1141 SortResponse member resultCount now set to NULL in sort handler of
1144 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1147 Add three new utility functions for translating OIDs between various
1148 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1149 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1150 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1151 char *oid_to_dotstring(const int *oid, char *oidbuf);
1152 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1154 Reverted modifications for ES Update definition for z_IU0Update
1155 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1156 is back to YAZ 2.0.2.
1158 String value attributes for CCL parser.
1160 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1161 which their FirstSearch server returns in Init responses, sometimes
1162 carrying useful diagnostic information when Init fails. This has the
1163 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1164 "z39.50/oclcui.asn", where its definition is somewhat different from
1165 what OCLC document on their web-site, as required to interoperate with
1168 Support for anonymous authentication in yaz-client. Use the command
1171 * Fix the OID of the Index Data-local "admin" Extended Service from
1172 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1173 the 1000, which indicates a locally-defined OID, was a mistake.
1175 --- 2.0.3 2003/06/20
1177 Fix CCL directive @case handling so that it affects string match for
1178 both CCL keywords and qualifiers.
1180 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1181 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1182 Decoder has been updated with ASN.1 changes as listed in
1183 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1184 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1185 z_IUUpdate, remains unchanged.
1187 ZOOM_record_get may now return a record in a specific character set.
1188 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1189 "from" is the character set of record as returned by target. "to" is
1190 the character set to be returned. If omitted, "to" is UTF-8.
1192 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1194 New ODR utility, odr_getelement, which returns name of element for
1195 which encoding/decoding failed.
1197 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1198 in cases where a required element was omitted.
1200 Bug fix: some MARC8 sequences were not converted.
1202 New ZOOM option "step" which specifies number of records to be
1203 retrieved in one chunk. Used in conjunction with "start" and "count".
1205 SRW support for yaz-client. Use scheme http: to use it, e.g.
1208 yaz-client no longer does (un)intelligent character set conversions
1209 by default. Can be enabled with charset and marc_charset commands.
1211 xmalloc trace fix for 64-bit systems such as DEC alpha.
1213 Solaris 2.6 compile fix.
1215 New function, cql_strerror() translates SRW error codes, as returned
1216 by cql_transform_error(), into human-readable English strings. Used
1217 in yaz-client diagnostics when appropriate.
1219 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1220 converts it into a type-1 query which is sent to the server. This
1221 makes CQL available for use with all Z-servers, as opposed to the tiny
1222 minority that can handle CQL queries themselves.
1224 --- 2.0.2 2003/04/28
1226 New Debian package layout similar to the Redhat Package layout.
1228 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1229 and search result respectively.
1231 --- 2.0.1 2003/04/25
1233 Redhat package is now several packages: libyaz (runtime libraries),
1234 libyaz-devel (development and documentation, and yaz (utility programs).
1235 Package spec file by Morten Bøgeskov.
1237 New member 'schema' in struct bend_fetch_rr which the name of requested
1238 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1239 handler MAY set this to reflect the schema of the returned record.
1241 New member 'display_term' in struct scan_entry. GFS now sets member entries
1242 and allocates scan entries to be filled by user scan handler. In previous
1243 version, entries member was allocated by the scan handler. That still works,
1244 but the GFS will ignore member display_term - assuming it was NOT set by
1245 the handler. The fact that the GFS now allocates the entries both allows
1246 for new members and makes a scan handler easier to write.
1248 Fix CQL lex buffer overflow.
1250 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1251 SRU default recordPacking is string.
1253 SRU protocol support for frontend server.
1255 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1257 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1259 Added scan for the ZOOM shell (zoomsh).
1263 * String Identifers for Schemas (Amendment 5).
1264 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1265 Old definition for schema
1266 Odr_oid *schema; /* OPT */
1271 Z_InternationalString *uri;
1272 #define Z_Schema_oid 1
1273 #define Z_Schema_uri 2
1276 * resultCount parameter to Sort Response (Amendment 1).
1277 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1279 Support for SRW 1.0 over HTTP. This is an optional feature and
1280 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1283 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1284 on the same port. SRW SearchRetrieveRequests are mapped
1285 to bend_init,bend_search,bend_fetch,bend_close.
1287 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1289 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1290 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1292 ZOOM connections are SRW based if schem http is used for hostname
1293 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1294 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1296 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1297 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1298 distance=n, order=true/false, relation=le, prox unit=word. If
1299 n is omitted, distance 1 is used.
1301 Fixed problem with C compiler include path in wrong order.
1303 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1304 on Solaris. Patch from Ko van der Sloot.
1306 New MARC decode API. All new functions operate on a yaz_marc_t
1307 handle. The most important new functions are: yaz_marc_create,
1308 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1309 decode and destroy respectively. Decoder can produce formats
1310 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1311 include/yaz/marcdisp.h.
1313 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1314 to UTF-8, UCS-32, wchar_t or Latin-1.
1316 * Prototypes for yaz_iconv_-functions moved to separate header
1317 include/yaz/yaz-iconv.h.
1319 Make a few private functions 'static' in unix.c. This prevents
1320 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1322 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1323 are set when Init Response is received.
1325 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1326 but returns diagnostic set as well.
1328 New function yaz_strerror which is a portable wrapper for
1329 strerror/strerror_r/GetLastMessage.
1331 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1332 is returned for MARC. If type is "oai", then OAI MARC is returned.
1334 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1337 --- 1.9.2 2002/11/26
1339 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1341 Fix bad race conditions on SIGTERM and terminate gracefully in
1344 Move retrieval (data1) module to Zebra since nobody seems to be
1347 Add GRS-1 render for ZOOM using same format as yaz-client.
1349 --- 1.9.1 2002/10/05
1351 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1353 Fix broken ESpec handling in data1 module.
1355 SGML reader parses comments and makes them part of the data1 tree.
1357 Added several type casts so that YAZ compiles as C++ code.
1359 ZOOM didn't handle PDU encoding failures properly.
1361 Added more Bib-1 diagnostics (approved extensions).
1363 GNU configure: better check for iconv.
1365 More portable use of accept, getpeername. Check for socklen_t. Use
1366 int/size_t if socklen_t is not defined.
1370 PQF parser rejects bad queries - including those with extra
1371 characters in them. PQF parser used to silently ignore that.
1372 Cleaner API for PQF added, which allows you to get detailed
1373 error information for bad queries (see yaz/pquery.h).
1375 Fixed bug in ZOOM_record_get for type "database".
1377 Implemented mini iconv library supporting conversions between
1378 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1380 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1382 --- 1.8.9 2002/08/20
1384 Fixed ZOOM C record cache so that preferredRecordSyntax and
1385 elementSetName is used to check for already fetched records.
1387 --- 1.8.8 2002/08/02
1389 Added three members in bend_initrequest structure to facilitate
1390 character set negotiation.
1392 Fixed a bug in frontend server that could cause indefinite
1393 loops under rare conditions.
1395 Revised character set utilities (charneg.h) so that encoding
1396 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1398 For PQF, directive @term <type> sets term type for Scan/Search.
1399 Here <type> is general, string, numeric, null. The term type
1400 is inherited - just like @attr.
1402 New call odr_set_charset that sets character set conversion for
1403 international-strings on a ODR stream. Prototype is:
1404 int odr_set_charset(ODR o, const char *to, const char *from);
1405 The InternationalString is still represented as C string in YAZ
1406 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1407 won't). On the protocol level, you can use any encoding.
1409 Support for UNIX sockets in ZOOM.
1411 Solaris recv sometimes returns errno == ENOENT. It is treated as
1412 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1414 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1415 both client and server. Code by Morten Bøgeskov.
1417 --- 1.8.7 2002/05/22
1419 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1420 that they can be used directly from Visual Basic. You must recompile
1421 your windows APP if you're using ZOOM.
1423 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1424 Commands "lang" and "charset" sets language and character set respectively.
1425 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1426 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1428 Attributes from multiple CCL fields may be OR'ed rather than merged
1429 using directive "@field or". Fields are still merged by default -
1430 equivalent to "@field merge".
1432 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1435 Fixed bug in zget for parameter ExtendedServicesResponse.
1439 --- 1.8.6 2002/03/25
1441 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1443 Client displays USR.1:SearchResult-1 (hits per term).
1445 Additional Search Info for search in Generic Frontend Server.
1447 Fixed CCL parsing of "field=s".
1449 WIN32 installer - using the excellent NSIS software from nullsoft.
1451 Fixed CCL parsing of "field = - <number>".
1453 Added function yaz_marc_decode that decodes MARC for line mode
1454 display or XML (similar to that used by JZKit).
1456 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1457 Z39.50. But ISO/ILL was, however.
1459 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1460 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1462 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1463 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1465 --- 1.8.5 2002/02/03
1467 New YAZ client features: Command completion and new commands:
1468 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1469 Code provided by Jacob Poulsen.
1471 New call oid_trav, that visits all registered OIDs via callback.
1473 Function ZOOM_record_get now returns const char pointer rather than
1474 void pointer. It saves a lot of type casts.
1476 For YAZ client, command "auth" now allows you to set authentication
1477 in IdPass style. It is enabled when three tokens are given - order
1478 is user, group and password.
1480 Fix memory leaks in MARC record handling for ZOOM.
1482 New option for YAZ client, -k <kilobytes> that sets
1483 maximum record size. Similar to -k option for generic frontend
1484 server and yaz-ztest.
1486 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1488 Prefix query parser reports "fail" when bad attribute set is given.
1490 Fix in MARC decoder. Proximity logging. Fix for attribute set
1491 in scan handler for server. Patches by Shigeru Ishida.
1493 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1496 Configure option --with-openssl=<dir> now works when a directory is
1497 specified. Patch provided by Morten Bøgeskov.
1499 New option for YAZ client, -u <auth>, that sets authentication.
1501 ZOOM fix: error information was sometimes "missing", since error
1502 was cleared/reset too when it shouldn't.
1504 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1506 --- 1.8.4 2002/01/04
1508 Scan for ZOOM API. New object ZOOM_scanset. New functions
1509 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1510 ZOOM_scanset_destroy.
1512 New ZOOM function, ZOOM_connection_last_event, that returns type
1513 of last event (such as "receive data", "send data", "apdu received",
1516 New ZOOM option, schema, that specifies schema for retrieval.
1518 New CCL feature. Qualifiers can be aliases for one or more
1519 other qualifiers (if more than one is given, OR is used).
1521 ZOOM uses named result sets if target supports it.
1523 Two new YAZ client commands: . (dot, which sources a script of YAZ
1524 client commands), and ! (to execute shell command.). Implemented
1527 Working on Debian packages.
1529 --- 1.8.3 2001/11/19
1531 YAZ client enables named result sets only if target supports it.
1533 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1535 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1536 with key="host" to get same result.
1538 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1539 Function Z3950_resultset_record(s) returns references to records
1540 "owned" by resultset. To become owner use Z3950_record_clone.
1542 Function z_ext_record handles Extended Services. Thanks to
1545 --- 1.8.2 2001/11/12
1547 CCL Parser fix: ignore token comma when dealing with and-lists.
1549 Documentation updates for COMSTACK.
1551 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1552 Changed prototype Z3950_records. For some functions, int parameters
1553 were changed to size_t.
1555 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1558 New MARC decode/display function, marc_display_exl, which properly rejects
1559 non-ISO2709 records. YAZ client uses it.
1561 --- 1.8.1 2001/10/29
1563 Fix bug: local attribute set wasn't set correctly in PQF strings.
1567 * Old Z39.50 codecs no longer supported.
1569 Added ZOOM C binding. See http://zoom.z3950.org/
1571 Renamed states for COMSTACKs to avoid confusion with events.
1573 Implemented cs_look and proper cs_rcvconnect.
1575 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1577 Configure detects POSIX threads on OpenBSD.
1579 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1580 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1582 When error is returned from present handler, non-surrogate diagnostic
1583 is returned in present response (and fetch handler is no longer called).
1585 * Minor adjustments to pquery parser (PQF). Token characters may be
1586 escaped by using backslash (C-style).
1588 PQF parser allows string attribute values to be specified. For @attr,
1589 non-numeric characters after the equal-sign are treated as strings
1590 (e.g. @attr 9=title).
1592 CCL trunction character may be defined (@truncation in file)
1594 * function zget_ExtendedServicesRequest sets waitAction to
1595 waitIfPossible (was wait).
1597 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1600 CCL operator names may be set in field definition files (CCL_bibset).
1601 See ccl/bib1 for an example.
1603 Fixes in ASN.1 compiler for C++ compatibility.
1605 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1606 and "op_or" to avoid conflict with C++.
1608 Fixed problem with GNU readline detection on Redhat 7.0.
1610 Added step-size for Scan backend handler.
1612 Fixed bug that made the frontend server crash when no attribute
1613 set was specified for scan.
1615 Front-end server automatically switches to original working directory
1616 when installed as an NT service. Previously -w had to be specified to
1619 Added extended attributes for retrieval module (data1), so that data1
1620 records carry d1_readXML/SGML attributes. d1_read also supports
1621 null-data rules ( <tag/>)
1623 On UNIX when POSIX threads are available, a separate library libyazthread
1624 is created. Programmers should link with that library and the yaz library
1625 when using threads. The reason for the split was that some applications
1626 on Linux, such as Apache, doesn't work well when using shared objects that
1629 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1630 (or any frontend server) in SSL mode by specifying ssl: followed by
1631 address. Only tested on UNIX.
1633 Added feature for CCL module. Virtual structure s=al or s=ol generates
1634 and-list and or-list respectively instead of phrase search.
1638 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1639 log_mask_str. This was done to avoid name conflicts with other libraries
1640 (such as other PHP extensions).
1642 Added raw OID member for preferred record syntax (request_format_raw)
1643 and returned record syntax (output_format_raw) for backend fetch method.
1645 Config file yaz-config now accepts options so that it returns specific
1646 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1648 Shared library support for UNIX using GNU libtool.
1650 * Modified backend interface. Request/Response struct's replaced by
1651 one read/write C struct. For example bend_fetchrequest and
1652 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1653 Every handler - even search has to be registered in bend_init
1654 handler. This means that the YAZ library no longer refers to
1655 external functions and it makes it possible to make the whole
1656 thing a single DLL/SO.
1658 Added Segment handler for backend server.
1660 Added Zmbol/Zebra administrative functions to YAZ client.
1662 Threaded frontend server on UNIX (when POSIX Threads are available).
1663 Starting the server with option -T enables multi-threading.
1667 Added configure option --enable-comp/disable-comp to control use
1668 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1669 located in sub directory asn.
1671 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1672 in ${exec_prefix}/bin along with the other programs yaz-client and
1675 GNU automake used to maintain makefiles.
1677 Added several OID's.
1679 Changed retrieval module so that we can load records with no abstract
1680 syntax defined. Tagpaths in these records are fully composed of string
1683 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1687 On UNIX, the generated makefile now supports a proper 'make install'.
1688 The prefix can be set via GNU configure to set the install location
1689 (default is /usr/local).
1691 * YAZ programs client and ztest were renamed to yaz-client and
1692 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1693 locations, such as /usr/bin,/usr/local/bin,etc.
1695 * YAZ Header files were moved from include to include/yaz. YAZ Header
1696 files are referred to as include <yaz/log.h> rather than <log.h>.
1697 The YAZ include path (-I ..) is therefore the same as before. Programmers
1698 should update their #include statements or use -Ipath/include/yaz
1699 instead. The main motivation for doing this change is that YAZ header files
1700 can be installed in "standard" locations /usr/include,/usr/local/include
1701 without introducing conflicts, since ALL YAZ header files are stored
1702 in subdirectory yaz (under /usr/include for example).
1704 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1705 rather than project/workspace files. We switched because project files
1706 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1709 Changed name of logging function, logf, to yaz_log, to prevent name
1710 clash with some math-log functions. The YAZ header log.h defines logf
1711 to yaz_log (#define) so there should be no incompatibilities by this
1714 Added bend_start/bend_stop handlers for server. These handler are
1715 called on start/stop of server. For windows they are called whenever
1716 a service is started/stopped.
1718 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1719 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1720 in util/yc.tcl. The auto-generated C code structures are, in a few
1721 cases, incompatible with the old decoders. There are differences in the
1722 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1723 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1724 The preprocessor variable ASN_COMPILED is defined when the compiled
1725 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1726 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1727 wish to use the old encoders/decoders you can specify --disable-yc
1730 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1731 version so that it supports both new - and old version of DB Update
1733 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1734 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1735 change. The name parameter can be set to 0 in which no name is specified
1736 for the construction. The macros odr_implicit and odr_explicit sets name
1737 parameter to zero for the construction involved. New macros
1738 odr_implicit_tag and odr_explicit_tag are similar to the others,
1739 except that a name parameter is added. For programmers' that don't use
1740 ODR they probably only need to change the call to z_APDU and z_External.
1742 Added access control facility by interfacing the TCP wrapper library.
1743 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1744 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1745 name of the daemon and enables the access control as specified in
1746 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1748 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1749 den Dool <H.M.vdnDool@kub.nl>.
1751 Added reference ID parameter to most functions in server API - refer
1752 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1754 Changed name of ccl library to libccl.a (was ccl.a).
1756 Fixed bug in decoder for Explain (Category TargetInfo).
1758 Added support for GNU readline in client. Thanks to Jacob Poulsen
1759 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1761 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1762 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1763 IMPLEMENTATION! This change was made to the development version before
1764 the ZIG decided to retract the amendment. If any users MUST be
1765 compatible with the original Update definition, PLEASE CONTACT US, and
1766 we will include a separate definition corresponding to the old Update
1767 ES. Note that because of the change to the ASN.1 of the
1768 TaskPackageRecordStructure we cannot define a single structure that
1769 will support both versions.
1771 * Added const modifier to buffer parameter for some ODR/BER encoding
1772 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1773 completeWAIS, odr_dumpBER.
1775 Fixed bug in client.c which caused a crash when a scanResponse didn't
1776 contain positionOfTerm.
1778 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1779 * will cause an error in a client if a non-YAZ target sends both a
1780 * list of Scan entries and non-surrogate diagnostics.
1782 Retrieval module enhancements. Tag sets may be typed in the reference
1783 to it. From the .abs-file the "tagset" directive takes a third optional
1784 integer type for the tag set referenced. From a .tag-file the "include"
1785 directive takes a third optional type as well. The old "type" directive
1786 in the tag set itself is still recognized but acts as the default type
1789 Backend interface change. Individual Scan terms returned from bend_scan
1790 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1791 in include/backend.h.
1793 Retrieval module enhancements. Multiple tag sets and attribute sets may
1794 be specified in abstract syntax specs. Revised the error/warning for
1795 logging messages reported by the retrieval module when reading the
1798 Object Identifier system (oid_..) changed. The API is backwards
1799 compatible but the oid-routines now allocates new OID's when needed.
1800 Raw OID's may be specified in oid_getvalbyname.
1802 YAZ now uses GNU configure to generate Makefile(s).
1804 * Minor changes in some of the member names of DeleteResultSetRequest and
1805 DeleteResultSetResponse. See include/proto.h.
1807 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1808 and added member 'languages' in TargetInfo (which was missing).
1810 Changed the way attribute sets are handled in the retrieval
1811 module. These are now cached, just like the abstract syntaxes
1814 Changed YAZ so that it links with compiled ASN.1.
1816 Added Explain-schema definitions and mapping routines. The following
1817 Explain categories have been implemented: AttributeDetails,
1818 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1820 Fixed minor bug in Windows version of Server Library.
1822 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1824 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1826 Added EXTERNAL: UNIverse Resource Report (non-standard).
1828 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1829 ENUMERATED and SET OF.
1831 * Added 'const' to some of the char pointer arguments for the
1832 functions, data1_read_node, data1_getelementbytagname,
1833 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1836 Fixed bug in data1_insert_taggeddata - the last_child member of
1837 parent wasn't initialised.
1839 * Changed data1_read_record and data1_read_node so that the supplied
1840 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1841 doesn't refer to any parts of the "SGML"-buffer.
1843 Fixed bug in server library (Windows version of statserv_remove).
1845 * Changed code so that it compiles as C++. The type definition
1846 of Odr_fun which is a member of Odr_arm was changed. The result is,
1847 that an explicit typecast is needed for the fun pointer when
1848 using Odr_arm - as in:
1849 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1851 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1853 Implemented the new structured date and time definition as approved
1854 by the ZIG. Added schemaId element to the specificTag in Espec-1
1855 (also approved at the last ZIG). Thanks to RVDM.
1857 Added some Object identifiers (RVDM).
1859 Changed the Update Extended Service (RVDM).
1861 Added command "refid" to client which specifies referenceId for
1862 the following requests.
1864 Implemented extended service handling for server. See ztest.c
1865 for an example as well as backend.h. New handlers are registerd
1866 in the Init handler.
1868 * Changed interface for sort in server.
1870 Added new members to statserv_options_block. It allows a server
1871 to read options from another source than just the command line. Thanks
1872 to Charles Woodfield.
1874 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1875 renamed to zboolean. Some C++ compilers complained about the name.
1877 Minor changes to gils.abs. Added index 's' (sort) on title
1878 and date/time-last-modified.
1880 --- 1.4pl2 1998/1/30
1882 Fixed bug in server library regarding inetd mode (-i). This bug
1883 was introduced by release 1.4.
1885 --- 1.4pl1 1998/1/29
1887 Added sort facility in client and backend server interface.
1889 Fixed problem with dependencies in Makefile(s).
1891 Fixed bugs for encoders/decoders of extended services and
1894 Implemented sub-tree feature for schemas. Sub-trees are
1895 referenced in *.abs-files. See explain.abs for an example
1896 of the use of this feature.
1898 Modified bib1.att; local attributes for ANY didn't include
1899 ANY itself (only affects use of the retrieval module).
1901 Fixed bug in plain SGML reader in function data1_read_node:
1902 tags with prefix "var" was incorrectly interpreted as variants.
1904 Added feature "sub-schemas" to enable references to - and definitions
1905 of - group of elements.
1907 * Removed member parent from type data1_element (in data1.h).
1909 Implemented function odr_nullval() that returns the value of
1912 * Removed member num_children from data1_node (in data1.h).
1914 Made NT service interface part of the server library. The
1915 function statserv_main uses the NT service when required and
1916 calls the statserv_start / statserv_close routines.
1918 Routine zget_SearchRequest and zget_PresentRequest fills
1919 resultSetName/Id member with "default" instead of "Default".
1921 Fixed memory leak in server. Request queue member wasn't freed.
1923 Fixed nmem_exit so that memory is freed.
1927 Revised the CCL parser utility to be thread safe.
1929 Added function, oid_ent_to_oid, to replace the function
1930 oid_getoidbyent, which is not thread safe.
1932 * Added nmem_init and nmem_exit to initialize and release
1933 NMEM resources. Function nmem_init should be called once in the
1934 initial thread before NMEM/ODR is used. statserv.c and client.c
1935 have been changed accordingly. The change was necessary to make
1936 NMEM thread safe. The NMEM memory pool is shared amongst threads
1937 in a process. Unix-based applications will still work fine without
1940 Added NT Services interface for the the Z39.50 (statserv) Server.
1941 Refer to the ztest.c source on the usage.
1943 Windows 95/NT port using MSVC5.0. Project files are included in the
1946 * Defined new 'global' handle for the retrieval (data1) system. The
1947 new handled, data1_handle, describes the state of the data1 system.
1948 This handle is passed as first argument to virtually all
1949 data1 related routines. The functions data1_create and data1_destroy
1950 creates and destroys a data1 handle respectively.
1952 Added ODR encode stream member to all backend request structures
1953 init, search, scan etc. This stream should be used to allocate all
1954 memory used for the response when thread safe operation is needed.
1956 Changed the comstack utility, cs_addstr, to be thread safe. The
1957 returned hostname string returned by the function is now part the
1960 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1961 function. The cs_straddr takes a COMSTACK handle as argument, so this
1962 function must be used after cs_create and before bind/connect.
1963 This function is thread safe.
1965 Moved test server to 'ztest' directory - generic server code still
1966 in 'server' directory.
1968 Made prefix query (pquery.c) utility thread safe.
1970 Added new function modifier YAZ_EXPORT to 'export' public DLL
1971 functions when using windows (see include/yconfig.h).
1973 Added definitions to the OID database (util/oid.c) (RVDM).
1975 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1977 Added call to ccl_rpn_delete in client program.
1979 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1980 release of RPN structure.
1982 Added support for C++, headers uses extern "C" for public definitions.
1983 With input from RVDM.
1985 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1986 Thanks to Ronald van der Meer (RVDM).
1988 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1990 Added support for private extensions to the OID database
1991 (oid_setprivateoids()). Thanks to RVDM.
1993 Added optional, physical ANY (key replication)
1995 Fixed null-reference problem in GRS-1 output filter.
1997 Proximity operator added to Prefix Query Format (PQF).
1999 In test client command "base" accepts multiple databases.
2001 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2005 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2007 Smallish bug-fixes in the new encoders/decoders (explain).
2009 Bug fixed in DeleteRequest.
2011 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2013 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2015 Added SOIF syntax (using private OID for now) to retrieval module and client.
2017 Added Update extended service.
2019 Added SearchResult-1 additional info structure.
2021 Added optional CCL (ISO8777) interpreter as separate module. Available
2024 --- 1.2 1996/6/10 (1st anniversary release)
2026 Added Summary record syntax. Lightly tested.
2028 Added OPAC record syntax. Untested.
2030 Added ResourceReport service encoders/decoders. Untested.
2032 Fixed bug in z_Unit - wrong tagging on unitSystem.
2034 Fixed bug in the DiagRecs decoder.
2036 Added options for max PDU size and session timeout to frontend-server.
2038 Added documentation of query-language parsers and other supporting utilities.
2040 [frontend-server] Added Attribute set to the bend_scanrequest API.
2042 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2043 surrogate diagnostics were generated.
2045 [retrieval] Allow multiple local values for attribute.
2047 [retrieval] Allow multiple attributes per element in .abs files. index type.
2049 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2051 --- 1.1pl2 1996/4/10
2053 Minor changes, mostly specific to Zebra's requirements (retrieval)
2057 Repaired bug in frontend server when running multiple listening
2058 endpoints in dynamic mode.
2060 z_External() now won't break if a known, ASN.1 value comes encapsulated
2061 in an octet-string. The value will pass through unmodified in an Odr_oct.
2063 Added a bit of code to the demo client to decode & display
2064 ASN.1-structured records represented in the octet-aligned branch of
2065 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2067 Added z_ext_getentbyref() to the ASN module. Doc updated.
2069 * Completed the SCAN definition in the ASN module. This may break SCAN
2070 code based on older YAZ-versions at compile-time. The fix is easy -
2073 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2074 under the SCAN definition. Remember to initialize this, server-people.
2076 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2077 that this does not extend to ODR and ASN.
2079 Comstack allows insertion of established socket (primarily for
2080 inetd-operation of servers). Doc updated.
2082 Front-end server can now start from the inetd in TCP mode. Doc
2085 --- 1.0pl4 1996/1/24
2089 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2090 the rank and record number.
2092 Adjustments to the frontend server.
2094 Fixed diagnostic BER dumper. It ignored the file argument.
2098 Various changes to retrieval module.
2100 Changed the union discriminators of the protocol files from enums to
2101 ints paired with #defines.
2103 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2106 *Changed operator in the RPN structure to 'roperator', again to avoid a
2109 Fixed problems in Explain decoders/encoders.
2111 --- 1.0pl2 1995/12/6
2113 Memory bug in log module fixed.
2115 --- 1.0pl1 1995/12/5
2117 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2119 Bug in Explain DatabaseInfo module fixed.
2121 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2125 The shift to v1.0 signals that we now consider the *core* functionality
2126 of YAZ reasonably stable (the core being more or less equivalent to
2127 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2128 tested (Explain not at all - though that will happen soonish).
2130 Minor changes to code to support Windows port.
2132 Various minor changes after we're getting to use GRS-1 & co. more.
2134 Added Espec-1 format.
2136 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2137 of the protocol and it cannot be selected when encoding (maps into 'string'
2138 when decoding). Needed to talk to some servers.
2140 Demo client can request simple element set names.
2142 Added Diagnostic Format encoders/decoders.
2144 Added simple Close handling to frontend server (no hooks for resource
2145 reporting yet), and demonstration client.
2147 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2149 --- 1.0b3 1995/08/24
2151 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2152 handled incorrectly when records were requested in the searchResponse. This
2153 will only affect you if you use the frontend-server.
2155 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2156 Test-client will ask for and print GRS1. Ztest will return dummy records
2159 Added Explain encoders/decoders to the service-level API. Untested.
2161 Added Extended Services: Item Order encoders and decoders to the Service-
2162 level API. Untested. We could use a recent copy of the pertinent bits
2163 of the ILL protocol to add those bits.
2165 Added diagnostic format 1 encoders/decoders to the service-level API.
2168 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2169 odr_cons.c, which causes a more correct output.
2171 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2172 was always set to 0 when no records were requested in the searchRequest.
2174 * Added better external-handling. This shouldn't harm old code that
2175 *encodes* externals. It can break code that looks for a
2176 'single-ASN1-type' representation, since those types that are known
2177 are now decoded immediately. Look at the SUTRS sample code in
2178 seshigh.c and client.c. Documentation updated.
2180 Handling of structured records in bend_fetchresponse. Length -1 marks
2181 structured record, type is deduced from format field.
2183 --- 1.0b2 1995/06/27
2184 Fairly quick maintenance release to add SUTRS support.
2186 Fixed handling of SUTRS records in the demonstration client.
2188 * Added format field to the bend_fetchrequest and bend_fetchresponce
2189 structures of the backend API (frontend server). When the record is
2190 returned, the value of the format field is mapped to an OID. The
2191 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2192 of the record. The special value VAL_NONE in the bend_request means
2193 that no specific format was requested by the client. Documentation
2194 updated accordingly. Test server (ztest) will return a fixed dummy
2195 SUTRS record if your client requests SUTRS.
2197 Documentation updated accordingly.
2199 You can now set external libraries and RANLIB support in the top-level
2203 First public release.
