1 Allow elementSetName to be specified for ZOOM C record update.
3 Allow waitAction to be specified for ZOOM C based for Extended Services.
7 Fixed bug #1157: yaz-client does not read .yazclientrc from current
8 directory. yaz-client now reads commands from file given by option -f
9 if specified; then tries to read .yazclientrc in current directory.
10 Failing that, it reads .yazclientrc from user's home directory.
12 Added support for correlationInfo Note and ID for Record Update via
15 Added yaz-client command querycharset which specifies character set for
16 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
17 (termListAndStartPoint).
19 Charset ISO5428:1984 is an alias for ISO5428-1984.
21 Implemented a way to perform scan in a result set using Z39.50. This
22 is achieved by attaching the result set name in the characterInfo
23 (type InternationalString) of OtherInformation in the Scan Request PDU.
24 The result set is identified in the otherinformation by the new OID:
25 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
26 This allows for scan in result set and faceted search . Zebra did some
27 of this in the APT term using attribute type 8 and value being result
28 set. Using the OtherInformation approach for this is cleaner and easier
29 to work with in proxies and the like. This facility can be used in
30 yaz-client using new command setscan which takes a result set as first
31 argument, start position (APT) as second.
33 Changed decoding of SRU XML packed records to deal with servers that
34 have recordData with XML data with multiple root nodes. Also make
35 comparison for recordPacking case insensitive. Again, one server
36 returns "XML" where others return "xml".
38 For SRU responses allow Content-Type application/xml as well as text/xml.
42 Fixed bug in character set conversion of BER strings. Bug introduced
47 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
49 For OID class, use oid_class consistently.
51 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
54 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
55 character set for bibliographic information interchange". By Giannis Kosmas.
57 Added documentation on new OID API.
61 Changes to generic frontend server interface: added new member
62 'query_charset' for bend_initrequest structure. A backend init handler
63 should set this member to its native character set for query terms.
64 When defined, the frontend server logic will announce this character set
65 to a client if the negotiationModel bit is set by the client. All server
66 implementors are encouraged to specify this. If a backend server does not
67 specify this a warning is issued using yaz_log(YLOG_WARN,..).
69 Added CCL utility to remove terms (stop words) from resulting RPN
70 tree. This is handled by functions with prefix ccl_stop_words_ .
72 New ZOOM C option, "rpnCharset", which allows client-side conversion of
75 Clean-up the CCL API. Moved some internal structures from ccl.h to
76 private header cclp.h. Changed ccl_parser_create so that a Bibset must
77 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
78 This is replaced by ccl_parser_find_str which takes a string instead.
80 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
81 libyaz.la is the core of YAZ except the generic frontend server and
82 does not depend on POSIX threads anymore. libyaz_server.la is the
83 generic frontend server facilities and uses POSIX thread functionality
84 if available. The libyaz.la no longer depends on POSIX threads because
85 the number of global structures is limited. NMEM no longer re-uses blocks
86 between threads ; it simply free's memory immediately but allocates in
87 "large" chunks as usual. We don't expect any performance penalties
88 because of this. The yaz_log system is still using a global log_level so
89 caution must be taken when modifying it with yaz_log_init_.. +
90 yaz_log_mask_str. This, however, should not cause any trouble because
91 these functions are called during initialization of application code
92 anyway. `yaz-config --libs server` returns libs for server applications;
93 `yaz-config --libs` returns libs for non-server applications.
95 New OID database - with public definitions in oid_db.h. Removed old OID
96 database including the head oid.h and definitions such as enum oid_value
97 and struct oident. The new OID database uses the same string names as
98 before but the 'protocol' is gone. There are now only two representations
99 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
100 converts from string to OID; functions with prefix yaz_oid_to_string
101 converts the other way.
103 Change to emit_term() in CQL-to-PQF query translation: when a term has
104 the /regexp relation modifier, do not process it for leading and
105 trailing "^" and "*", which have quite different meanings in regular
108 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
109 write handlers no longer carries a 'last' parameter. This will make
110 yaz_iconv flush "less" characters. A flush is performed by call to
111 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
113 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
114 removed, because function yaz_query_to_wrbuf does the same.
116 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
117 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
119 Deprecated MARC utility functions removed.
121 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
124 Branch split: YAZ_2_1_55_branch
126 --- 2.1.54 2007/03/16
128 Fix to ZOOM-C so that transparent reconnection is properly handled on
129 connections that are in asynchronous mode.
131 Fixed compilation on OpenBSD 4.0.
133 Large strings in GRS-1 records are now properly displayed in yaz-client.
135 Added character conversion support for "advancegreek"; based on patch from
138 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
139 sequence is met. Before the error was not set so it would be unknown.
141 Adjust yaz-marcdump MARC reader so that it skips until record separator
144 --- 2.1.52 2007/03/07
146 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
147 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
148 fd_set structure used as a bitmask for the FDs to be selected on.
150 Using ACX_PTHREAD macro to check for POSIX threads.
152 Fixed have-vsnprintf check.
154 --- 2.1.50 2007/02/23
156 Fixes for configure on BSD. Bug #900.
158 Added snprintf/vsnprintf wrappers for systems that don't have
159 limits (heavens forbid).
161 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
162 created before all previous tasks were completed and removed from the
163 task queue, the new task could be removed by a mistake.
165 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
167 Implemented pass-through CQL-to-PQF conversions. Bug #861.
169 Fixed bug #832: Problem with MARC/charset in yaz-client.
171 Fixed bug #668: save command line history for yaz-client.
173 Fixed bug #830: pkg-config support.
175 --- 2.1.48 2007/01/23
177 Extended ZOOM result set options with two options that may be read by
178 a client: resultSetStatus and presentStatus with values as specified for
180 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
182 Fixed bug #827: Using SSL fails on Debian etch.
184 Fixed bug #826: Weird looking chars for set of MARC records.
186 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
187 that is treated as an ItemOrder with itemRequest being an XML document
188 external. The value of "doc" is the content.
190 Extended the GFS search facility. New member of bend_search_rr
191 'estimated_hit_count' signals that hits is known to be an estmate
192 (higher or lower than real hit count). New member 'partial_resultset'
193 signals that the search was partial (hit count is lower or equal than
194 real hit count). For Z39.50, the information is stored in resultSetStatus
195 member of SearchResponse APDU. For SRU, the information is signalled
196 via SRU diagnostic 59: "Result set created with valid partial results
199 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
201 --- 2.1.46 2007/01/13
203 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
205 Added ZOOM_connection_peek_event.
207 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
208 the following new functions:
209 ZOOM_event_nonblock, ZOOM_connection_process,
210 ZOOM_connection_get_{socket,mask,timeout},
211 ZOOM_connection_fire_event_{timeout,socket}.
212 The existing blocking event handler, ZOOM_event, is a wrapper for the
213 + blocking ZOOM_event_sys_{poll,select}.
215 Implemented function ccl_xml_config which parses XML version of CCL
216 configuration (bug #798).
218 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
220 Added timings utility (yaz/timing.h)
222 --- 2.1.44 2007/01/03
224 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
227 Fixed bug #779: Rotation of apdu.log fails.
229 Fixed for character set conversions:
230 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
231 Honor G1 set in MARC-8 decoding.
233 --- 2.1.42 2006/12/17
235 Fixed bug #775: char conversion does not handle Alternative UTF-8
238 Implemented function yaz_marc_read_line which parses MARC line format
239 records. There is a wealth of formats out there. So far, this function
240 reads line records produced by yaz_marc_write_line.
242 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
243 more generic and easier to remember(!) options: -i format and -o format
244 which specifies input format and output format respectively - where
245 format is one of "marc", "marcxml", "line", "marcxchange".
247 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
248 does not print anything except warnings for records.
250 For yaz-marcdump, added support for MARC split into files (-s) with a given
253 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
254 spec, at http://www.loc.gov/standards/sru/record-update/
255 This has changed the binary layout of the following structs:
256 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
257 bend_update_rr . Patch by Ko van der Sloot.
259 Added GFS utility function bend_assoc_is_alive which returns 1 if
260 association is still alive (client is connected); 0 otherwise (client
261 closed connection). This allows busy servers to stop working for
264 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
265 been a separate piece of software. This version of ziffy has been modified
266 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
268 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
270 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
271 Client code may now interrogate options such as "init_opt_sort" to
272 find out whether the server claims to support various options.
274 --- 2.1.40 2006/11/27
276 Added utilities yaz_{set,get}_esn to set/get element set name from
279 Removed the build of libyazthread.la. The libyaz.so is the threaded version
280 of YAZ and has been so since YAZ 2.1.10.
282 Implemented ZOOM_record_error which returns error information for
283 record (surrogate diagnostic).
285 --- 2.1.38 2006/10/31
287 Updates for SRU Update by Ko van der Sloot:
288 1. Changed name from "operation" to "action"
289 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
290 versions in the code, marked as 'backward compatible'.
291 3. Added diagnostics for SRU Update.
293 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
295 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
297 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
299 For GFS, fixed problem with SRU diagnostic 'First record position out of
300 range' being issued for 0 hits.
302 zoomtst10 part of Windows Build.
304 --- 2.1.36 2006/10/13
306 Implemented yaz_filepath_comp which splits a path into file path
307 components (required by Zebra 2.0.3+).
309 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
310 BSD inspired license until now so this should not have any real impact on
311 anybody. See http://www.opensource.org/licenses/bsd-license.php
313 Fixed bug #687: Missing log lines.
315 Fixed bug #678: CQL to PQF translation does not preserve double-quote
318 Fixed bug #689: SRU diagnostics to be added.
320 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
321 whether a connection is idle (no more work do do).
323 --- 2.1.34 2006/10/04
325 Change type of optval from long to int for invocation of setsockopt with
326 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
328 Added support for specifying the max log file size for the Generic
329 Frontend Server. The size is given with option -r.
331 --- 2.1.32 2006/09/21
333 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
335 --- 2.1.30 2006/09/17
337 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
340 Fixed bug in Generic Frontend Server that could cause a server to stop
341 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
343 For the generic frontend server, the maximum record size is used as maximum
344 size of incoming packages (SRU + Z39.50). The value until was previously
345 only used in Z39.50 Init negotiation and, later, in a session controlled
346 sizes of records returned. This is controlled using -k option. It can be
347 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
349 --- 2.1.28 2006/09/04
351 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
354 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
356 New option for yaz-marcdump -lpos=value which allows setting a portion
357 of MARC header to a certain value.
359 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
361 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
362 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
364 --- 2.1.26 2006/08/15
366 Fixed problem with SRU mode type (soap, get, post) for yaz-client
369 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
371 --- 2.1.24 2006/08/08
373 Fixed MARC ISO2709 encoding routines to deal with character set
376 Minor changes to GFS logging. Database included in search request log
379 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
380 cached/multiple records.
382 Shared libraries are built by default on Unix+configure.
384 Changed cql2pqf transformation to use a different evaluation order. The
385 new order is: always, relation, structure, position, truncation, index
386 and relationModifier. Old order was: always, relation, relationModifier,
387 structure, index, position, truncation. Note that the the latter ones
388 override former ones for identical attributes.. The new scheme means that
389 it is possible to override any existing attribute with a relationModifier.
390 And also that it is possible to override everything for the index rule
391 (except the ones listed in relationModifier). No order is perfect but this
392 one, we believe, covers more real cases.. The "always" should have been
393 called "default", since the attributes there can be overridden with all
396 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
397 compilation phase, but also for yaz-config --cflags output. This allows
398 us to have public headers with Libxml2 stuff in them . It should also,
399 eventually, make Libxml2 checks redundant in packages using YAZ, such
402 --- 2.1.22 2006/06/15
404 Changed SRU update structure bend_update_rr so that SRU diagnostics are
405 stored in uri, message and details.. Previously diagnostics were stored
406 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
407 compatibility.. but he's probably the only one affected, so.
409 Added support for CCL, compiled on the client side, in ZOOM-C. This
410 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
411 input; the resulting query objects can be used for for searching with
412 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
414 YAZ' configure searches for OpenSSL by default.
416 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
417 SL_CTX_use_certificate_file. See
418 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
419 for more info. Thanks to Ko van der Sloot.
421 --- 2.1.20 2006/06/02
423 Bug #600: SRU GET, POST support for yaz-client. Introduced
424 command 'sru' which selects method SOAP/GET/POST.
426 Allow missingValueAction to be specified for the sortspec string -
427 function yaz_sort_spec. By default, the missing value action is null.
428 Use ! to specify "abort". Use = followed by stringvalue to specify default
431 Ensured that Present-handler (if defined) is called in GFS before any call to
432 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
433 searchRetrieve requests.
435 Documentation for YAZ is now based on the Docbook XML/XSLT using
436 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
437 is no longer depending on jade/openjade or docbook-to-man scripts.
438 PDF is no longer part of the distribution - but can optionally be
439 made using DSSSL/jadetex or FOP.
441 Added retrieval handling support in Generic Frontend Server to support
442 conversion between MARC/XML as well as XSLTtransforms. See
443 etc/yazgfs.xml for an example.
445 Added Authentication support to Generic Frontend Server in SRU
446 mode. Authentication using HTTP Basic is supported, as is the use
447 of 'x-username' and 'x-password' parameters in the request itself.
449 Added support for a new character set MARC8s identical to MARC8 except
450 that it converts combined characters to single Unicode characters in the
451 Latin-1 range (when possible).
453 --- 2.1.18 2006/04/24
455 ASN.1 compiler 0.4: generates brief Doxygen file header for
456 generated .h/.c files.
458 Utility yaz_iconv now supports conversion to MARC-8.
460 New facilities for the MARC module. The reading - and writing of
461 content are separate methods for the yaz_marc_t handle. The following
462 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
463 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
464 format). Write functions have prefix yaz_marc_write_.. The existing
465 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
466 available. Removed support for OAI-MARC and simplexml (not the
467 simplexml from PHP5).
469 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
470 to be returned for this connection.
472 --- 2.1.16 2006/03/31
474 Allow multiple languages and charsets to be specified with
475 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
476 negcharset iso-8859-1,utf-8
478 Translation of proximity nodes from CQL into PQF now works.
480 Moved to automake 1.8, 1.9.
482 Added function yaz_log_set_handler which allows a log handler to be
483 installed. This handler will be called for all log messages. Output
484 to file is also produced; but that can be disabled by passing NULL
485 fname to yaz_log_init_file.
487 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
489 For SRW (including GFS), accept application/soap+xml as content-type
492 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
493 produces NO stylesheet reference even if a default stylesheet is specified
496 --- 2.1.14 2006/03/14
498 Updated Windows package to include yazd.dll + yazd.lib for the
499 Development component.
501 If the environment variable YAZ_LOG is set, then it is used as a
502 string indicating the default level of logging to use if not
503 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
504 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
505 used as before. So, for example, to omit warnings from YAZ logging,
508 cql_transform() now map structure and other attributes before indexes,
509 so that index-specific structures and other attributes can override
510 defaults. So now a combination of mapping specifications such as:
512 index.dc.date = 1=date-modified 4=5
513 does the right thing.
515 cql_transform() now also respects the "always" mapping specification,
516 which establishes an initial set of attributes to be used for all
517 terms except where overridden by more specific attributes associated
518 with the index, relation or modifier.
520 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
521 which mode to use; one of "post", "get" or "soap" (SRW, default).
523 Fixes for yaz_iconv routines: changed trie-based character set conversions
524 to use only non-negative values for bit fields due to Sun's C compiler not
525 supporting negative values.
527 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
528 sequences where not read correctly. Fix by Rustam Usmanov.
530 Updated win/makefile to use options, settings which makes things
531 compile with VS C 2005.
533 --- 2.1.12 2006/02/01
535 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
537 In ZOOM socket code, use select instead of poll on MacOSX.
539 ZOOM-C now support client-side compilation of CQL into RPN that is
540 sent to the server, enabling CQL to be used against all Z39.50
541 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
542 ZOOM_query object, and submit it using ZOOM_connection_search().
543 The CQL-to-RPN translation uses a configuration file, the name of
544 which must be specified in the Connection's "cqlfile" option.
546 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
547 function, which takes as its start-term parameter a ZOOM_query object
548 (which may have had either CQL or RPN set into it).
551 --- 2.1.10 2005/11/29
553 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
554 GFS to support this as well. Backend handler, bend_srw_update, does the
555 update work. Code contributed by Ko van der Sloot.
557 Allow retrieval of Search Result-1 information in ZOOM by the use of
558 options that are attached to a result set. ZOOM documentation updated
561 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
562 UTF-8 conversion. Patch by Raj Patel.
564 Added option -m to GFS to control formatting of timestamps in log file.
566 Added 'exit' as synonym for 'quit' in yaz-client
568 Added support for specifying SRW resultSetId + resultSetIdleTime in a
569 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
570 for the new members. Patch by Ko van der Sloot.
572 Added support for SRU POST. It is supported for content-type
573 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
575 Do not build the separate Multi-threaded (MT) library libyazthread.la.
576 Instead make the library libyaz.la multi-threaded. Threading as a whole
577 can still be disabled by configure option --disable-threads. Previosly,
578 with older GLIBCs there were problems with MT libs under Apache. This
579 has now been fixed a long time ago.
581 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
584 CQL module modified to be case insensitive for relations/indexes/operations.
586 Fixed bug in CQL transform code: incorrect value relationModifieder
589 Added 'show all' command for yaz-client which retrieves all results
592 Added new yaz-client, xmles, which takes a (private) OID and
593 a document to be sent as an extended service request.
595 Describe new yaz-client commands wait_response and set_auto_wait.
597 Increase TCP/IP listener backlog from 3 (which I am guessing was
598 copied from the SunOS manual entry way back when) so SOMAXCONN, so
599 that the socket will queue as many incoming connections as it's able
600 to handle ongoing connections. In other words, it will never now
601 refuse a connection that it would be able to handle merely because
602 it's not got around to accepting() enough of the pending connections
603 yet. This is the behaviour anyway under Linux, where the listen()
604 argument is ignored; but not under BSD and on systems such as
605 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
606 YAZ-based servers should now be uniform across operating systems in
609 yaz-marcdump uses 64-bit file access on some systems. This is enabled
610 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
611 This allows yaz-marcdump to read large MARC batches (>2 GB).
613 Modified all YAZ source files - except the source which is auto-generated
614 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
617 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
618 corresponding to the existing *_setl() function. These allow option
619 values containing arbitrary valuues.
621 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
622 ZOOM_resultset_sort() in new applications. Its behaviour is identical
623 except that it returns an indicator of whether or not the sort
624 criterion was accepted (0 for OK, -1 for invalid).
628 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
629 MARC output rather than returning "new" buffer.
631 yaz-client warns about unknown init options.
633 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
637 Added support for SRW sort in Generic Frontend Server. Patch
638 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
639 sortKeys - or NULL if none is provided.
641 Fixed bug #307: It was impossible to specify indefinite/no timeout
642 for ZOOM_event. Special timeout value -1 now means indefinite timeout
645 Added support for multiple languages and charsets to be specified in
646 ZOOM. Each charset/language is separated by a blank. If negotiation is
647 in effect in init-response, Option
648 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
649 Code based on patch by Vasiliy Osadchuk.
651 Fixed bug #306: infinite recursion that occurred when calling
652 yaz_log_level_init as the first call (before other log level or
655 Fixed bug in scan handling in front end server: if preferred-Position-In-
656 Response was non-present, a NULL pointer referece was performed.
660 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
661 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
662 now defined for all those error codes. So instead of putting 109 in
663 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
664 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
666 Modified the yaz-marcdump utility to skip garbage bytes between MARC
669 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
671 Program yaz-client now exits and produces an error message if multiple
672 Z39.50 servers are specified on the command line (none or one allowed
675 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
680 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
682 Fixed bug #272: Preserve spacing for CCL terms.
686 Added support for virtual hosts and multiple backend servers for
687 the YAZ frontend server. The configution is XML based and
688 support specificition of CQL to RPN mappings and explain information.
689 See section "Virtual Hosts" in the YAZ manual.
691 Extended OPAC display utility. OPAC display utility renders
692 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
693 to supplement yaz_marc_decode_wrbuf.
695 Fixed a bug in MARC decoder that could caused it to crash for some
696 invalid MARC records. More diagnostics and warnings where added in
697 XML output (warnings, etc are stored in comments).
699 --- 2.0.34 2005/02/08
701 Fixes for UNIX domain sockets. Bug #261.
703 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
705 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
706 Added yaz_marc_subfield_str which defines subfield lead string which is
707 used in YAZ_MARC_LINE format. Default string is blank+$. Added
708 yaz_marc_endline_str which defines end of fields string used in
709 YAZ_MARC_LINE format. Default string is newline.
711 Experimental support for MarcXChange. This format can be produced
712 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
713 http://www.bs.dk/standards/MarcXchange.xsd
715 Added yaz-client commands scansize that sets maximum number of
716 entries to be returned by scan.
718 --- 2.0.32 2005/01/11
720 Added support for SRW scan in yaz-client and Generic Frontend Server.
722 * Added whereInList member to SRW Scan Term.
724 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
726 Fixed NMEM system to return aligned blocks on the smallest boundaries
727 that are suitably aligned for all possible types on the particular
728 architecture YAZ is being built for.
730 --- 2.0.30 2005/01/04
732 Fixed numerious warnings that was issued with newer versions of GCC.
734 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
735 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
738 Make YAZ Generic Frontend Server slightly faster.
740 Enhance (and reduce) logging for Generic Frontend Server.
742 Revert YAZ log system so that it flushes every write operation
743 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
745 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
746 instead of LOG_, due to name clash with syslog(3). LOG_ are still
747 present. New applications should define YAZ_USE_NEW_LOG=1 - this
748 will effectively disable old definitions.
750 --- 2.0.28 2004/11/09
752 Added yaz_log_time_format which specifies log format using
755 Added yaz_log_module_level which returns mask for a module. Value
756 is non-zero mask a if module is enabled; zero if disabled.
758 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
759 in include/yaz/cql.h.
761 Fixed bug #176: Dont throw diagnostics on empty SRU args.
763 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
765 Fixed bug #172: RPM builds does not enable SSL.
767 Doxyfile.in part of dist. Doxyfile generated by configure.
769 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
770 are given and the corresponding component does not exist.
772 Extend CCL documentation in YAZ reference. Describe r=r.
774 --- 2.0.26 2004/10/01
776 Fixed MARC->MARCXML conversion to properly deal with
777 fields, subfields, indicators having non-ASCII characters.
779 Fixed MARC->MARCXML conversion so that ASCII control characters
780 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
783 Added YAZ GFS support for conversion from Z39.50 surrogate
784 diagnostics to SRW surrogate diagnostics.
786 Bug fix: YAZ GFS did not return schema in explainResponse.
788 --- 2.0.25 2004/09/30
790 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
791 now converts recordSchema to elementSetName as well as schema URI.
793 Fixed bug in COMSTACK that prevented HTTP request packages from being
796 --- 2.0.24 2004/09/29
798 Added CCL facility r=r "range" which is similar to r=o "ordered" but
799 does not require white-space before and after the dash in a range, e.g.
800 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
803 Fixed a few AC_TRY_LINK configure tests that did not operate properly
804 due to new GCC removing "redundant" code.
806 Added yaz-client commands scanpos and scanstep that sets preferred
807 position and step-size for scan.
809 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
811 Added CCL utility ccl_qual_buf which parses one or more CCL
812 spec lines in a buffer.
814 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
815 of name and value - ignoring empty lines and comments.
817 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
819 Added odr_get_element_path which returns current element path for an
820 ODR handle. This utility is useful in error handling or user-defined
823 Added ODR_PRINT utility odr_set_stream which is is a more generic
824 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
825 to a write function and pointer to close function. The close function - if
826 non-NULL - will be called during odr_destroy.
828 Fixed bug in CCL parser where truncation char was not removed from
829 right side when truncation=both was in effect.
831 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
834 --- 2.0.23 2004/08/11
836 Fix buffer overrun in CQL parser when dealing with proximity (%).
838 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
839 to UTF-8/UCS conversion is now only based on codetables.xml.
841 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
843 --- 2.0.22 2004/08/06
845 Add support for more "commit changes" in ZOOM (uses Extended Services).
847 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
850 Yet another small fix for configure of SSL.
852 --- 2.0.21 2004/05/14
854 Fix SSL libs for configure when --with-openssl=DIR is given.
856 --- 2.0.20 2004/05/10
858 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
860 SSL comstack now uses yaz.pem certificate file on server side
861 by default. Certificate filename can be configured by calling
862 comstack function cs_set_ssl_certificate_file before cs_bind is used.
864 Fix bug regarding multiple calls to ZOOM_connection_connect.
866 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
868 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
869 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
871 ZOOM now allows inspection of X509 peer certificate for verification.
872 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
874 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
875 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
876 as "modular" but it simplifies things.
878 Added cs_get_peer_certificate to that returns peer X509 PEM.
880 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
881 NULL if SSL is unavailable.
883 Documentation about MARC decoding tools.
885 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
887 --- 2.0.19 2004/03/30
889 Rename CHANGELOG to NEWS to follow GNU style packing.
891 Fix bug with missing initialization of member in init_diagnostics.
892 This bug affects threaded version of GFS server.
894 --- 2.0.18 2004/03/20
896 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
899 Ensure zlib.dll is packed with Windows install.
901 --- 2.0.17 2004/03/17
903 Fix encoding of xsd:string to use text instead of CDATA.
905 Fix endless loop in CQL parser with unbalanced ".
907 Use a more compact way to store MARC-8 conversion tables.
909 --- 2.0.16 2004/03/16 Debian only
911 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
914 Update CQL parser to use new CQL 1.1 modifiers for booleans and
919 --- 2.0.15 2004/03/01
921 Another fix for decoding of XML packed records.
923 --- 2.0.14 2004/02/25
925 Fixes for Chunked encoding. White space not ignored after length spec.
927 Update NS and use default NS for SRW diagnostic elements.
929 --- 2.0.13 2004/02/23
931 Implement ZOOM_resultset_cache_reset which resets record cache.
933 Implement ZOOM_resultset_sort which sorts a result set.
935 Implement chunked HTTP transfer.
937 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
939 --- 2.0.12 2004/02/16
941 Added member 'schema' to bend_explain_rr structure so that backend
942 can specify explain record identifier. Defaults to Zeerex 2.0.
944 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
946 --- 2.0.11 2004/02/16
948 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
951 Added init command for yaz-client which sends "extra" init request.
953 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
954 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
956 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
958 Make ZOOM error code for "invalid query".
960 Fixed compilation for SSL which wasn't properly enabled for all platforms.
962 --- 2.0.10 2004/02/05
964 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
967 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
969 Added option -p <file> to make Generic Frontend Server to write PID file.
971 Added option -D to put Generic Frontend Server in background on its own.
973 Make ZOOM C recognize option "password". If unset, "pass" is used
974 (for backwards compatibility).
976 Fixed a bug in Generic Frontend Server that could make it crash if a
977 client sets characterSetNegotation bit, but didn't pass negotiation stuff
980 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
981 Must be issued before open, in order to be in effect.
983 --- 2.0.9-6 2004/01/12 Debian/Windows
985 Make the SRU server more picky WRT unknown params, etc.
987 Bug fix: ZOOM scan response didn't return displayTerm - when present.
989 New YAZ client command, options, that sets Z39.50 options.
991 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
992 options from a string of tokens (one token for each option bit).
994 Update SRW diagnostic code messages.
996 --- 2.0.9-5 2004/01/07 Debian/Windows
998 Handle user defined stylesheet for SRW/SRU.
1000 --- 2.0.9-4 2004/01/06 Debian/Windows
1002 Fix bug in decoding of Content-Length.
1004 --- 2.0.9-3 2004/01/06 Debian/Windows
1006 Fix a bug with decoding of XML packed records.
1008 --- 2.0.9-2 2004/01/05 Debian only
1010 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1012 Fix bug in SRW/SRU diagnostics decoding.
1014 --- 2.0.9 2004/01/05
1016 Fixed bug in Generic Frontend Server which could drop records exceeding
1017 preferred message size. Reported and fixed by Irina Dijour.
1019 Fixed calculation of package size for structured records in Generic
1020 Frontend Server. Reported and fixed by Irina Dijour.
1022 Fixed namespace for SRW/SRU diagnostics.
1024 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1026 --- 2.0.8 2003/12/22
1028 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1029 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1032 CQL changes to reflect recent changes to the specification:
1033 * Documentation talks about context sets instead of index sets.
1034 * Documentation talks about indexes instead of qualifiers.
1035 * The CQL-to-PQF transformer's configuration file now uses
1036 "index.set.name = <attributes>" instead of the old form
1037 "qualifier.set.name = <attributes>". (Both forms are still
1038 understood but the latter is deprecated.)
1039 * CQL terms with no explicit index specified are now interpreted as
1040 cql.serverChoice instead of srw.serverChoice (which of course
1041 behaves exactly the same.)
1043 --- 2.0.7 2003/12/16
1045 MARC conversion can now generate ISO2709 output in another
1046 character set. yaz-marcdump uses this facility if you invoke it
1049 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1050 functions from there can be used from C++.
1052 --- 2.0.6 2003/12/04
1054 Frontend server now transfers memory from decoded packages to stream
1057 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1058 references to show up.
1060 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1061 the ZOOM Abstract API. The older names for the same options are still
1062 also supported for the benefit of old applications.
1064 ZOOM-C supports "implementationId" and "implementationVersion" options
1065 to go along with "implementationName". These allow the user code to
1066 specify identification strings to be sent to servers.
1067 Add OID for the new ExtLite attribute set.
1069 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1070 as requested/supplid by Ere Maijala <ere@atp.fi>
1072 For generic frontend server, reverse the order of
1073 "toolkit-supplied / application-supplied" strings sent as implementationId,
1074 Name and Version. Also, remove the spaces around the slash. This brings
1075 the GFS in line with the behaviour of ZOOM-C on the client side.
1077 Add function ZOOM_scanset_display_term.
1079 yaz-client shows scan displayTerm if present.
1081 Utility yaz-iconv is now installed by default along with the man page
1084 Extend configure check for OpenSSL to use pkg-config where available (such
1087 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1088 server to specify uid/gid/mask for socket using the format
1089 unix:[user=uid,][group=gid,][umask=mask,]file=path
1090 If file= is omitted the existing format is assumed, e.g.
1092 in which case the mask is 0666 (rw for everybody).
1094 Major restructure of YAZ source. All source in libyaz is in src directory.
1095 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1096 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1098 Added man page for utility yaz-marcdump (used to be called marcdump).
1099 yaz-marcdump is installed by 'make install'.
1101 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1102 of incoming package failed.
1104 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1106 Change prototype of odr_perror: add const to message string.
1108 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1110 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1111 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1112 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1113 DNS lookup. There should not be any compatibility problems with this
1114 assuming that blocking=1 or 0 is used.
1116 Fix bad reference in UNIX comstack in function cs_addrstr.
1118 Fix for compilation on AIX.
1120 The generic front-end server (server/seshigh.c) now supports returning
1121 Init diagnostics to the client in User-information-field, in
1122 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1125 --- 2.0.4 2003/09/04
1127 Allow any CQL relation (not just all,any,exact,scr).
1129 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1130 that features the same UI.
1132 Implemented command update0 in YAZ client which is equivalent to
1133 update but uses old of Ext Update ASN.1.
1135 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1136 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1137 Previously no OID was used for this info.
1139 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1140 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1141 returns 'malformed search term' otherwise.
1143 SortResponse member resultCount now set to NULL in sort handler of
1146 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1149 Add three new utility functions for translating OIDs between various
1150 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1151 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1152 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1153 char *oid_to_dotstring(const int *oid, char *oidbuf);
1154 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1156 Reverted modifications for ES Update definition for z_IU0Update
1157 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1158 is back to YAZ 2.0.2.
1160 String value attributes for CCL parser.
1162 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1163 which their FirstSearch server returns in Init responses, sometimes
1164 carrying useful diagnostic information when Init fails. This has the
1165 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1166 "z39.50/oclcui.asn", where its definition is somewhat different from
1167 what OCLC document on their web-site, as required to interoperate with
1170 Support for anonymous authentication in yaz-client. Use the command
1173 * Fix the OID of the Index Data-local "admin" Extended Service from
1174 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1175 the 1000, which indicates a locally-defined OID, was a mistake.
1177 --- 2.0.3 2003/06/20
1179 Fix CCL directive @case handling so that it affects string match for
1180 both CCL keywords and qualifiers.
1182 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1183 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1184 Decoder has been updated with ASN.1 changes as listed in
1185 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1186 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1187 z_IUUpdate, remains unchanged.
1189 ZOOM_record_get may now return a record in a specific character set.
1190 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1191 "from" is the character set of record as returned by target. "to" is
1192 the character set to be returned. If omitted, "to" is UTF-8.
1194 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1196 New ODR utility, odr_getelement, which returns name of element for
1197 which encoding/decoding failed.
1199 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1200 in cases where a required element was omitted.
1202 Bug fix: some MARC8 sequences were not converted.
1204 New ZOOM option "step" which specifies number of records to be
1205 retrieved in one chunk. Used in conjunction with "start" and "count".
1207 SRW support for yaz-client. Use scheme http: to use it, e.g.
1210 yaz-client no longer does (un)intelligent character set conversions
1211 by default. Can be enabled with charset and marc_charset commands.
1213 xmalloc trace fix for 64-bit systems such as DEC alpha.
1215 Solaris 2.6 compile fix.
1217 New function, cql_strerror() translates SRW error codes, as returned
1218 by cql_transform_error(), into human-readable English strings. Used
1219 in yaz-client diagnostics when appropriate.
1221 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1222 converts it into a type-1 query which is sent to the server. This
1223 makes CQL available for use with all Z-servers, as opposed to the tiny
1224 minority that can handle CQL queries themselves.
1226 --- 2.0.2 2003/04/28
1228 New Debian package layout similar to the Redhat Package layout.
1230 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1231 and search result respectively.
1233 --- 2.0.1 2003/04/25
1235 Redhat package is now several packages: libyaz (runtime libraries),
1236 libyaz-devel (development and documentation, and yaz (utility programs).
1237 Package spec file by Morten Bøgeskov.
1239 New member 'schema' in struct bend_fetch_rr which the name of requested
1240 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1241 handler MAY set this to reflect the schema of the returned record.
1243 New member 'display_term' in struct scan_entry. GFS now sets member entries
1244 and allocates scan entries to be filled by user scan handler. In previous
1245 version, entries member was allocated by the scan handler. That still works,
1246 but the GFS will ignore member display_term - assuming it was NOT set by
1247 the handler. The fact that the GFS now allocates the entries both allows
1248 for new members and makes a scan handler easier to write.
1250 Fix CQL lex buffer overflow.
1252 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1253 SRU default recordPacking is string.
1255 SRU protocol support for frontend server.
1257 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1259 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1261 Added scan for the ZOOM shell (zoomsh).
1265 * String Identifers for Schemas (Amendment 5).
1266 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1267 Old definition for schema
1268 Odr_oid *schema; /* OPT */
1273 Z_InternationalString *uri;
1274 #define Z_Schema_oid 1
1275 #define Z_Schema_uri 2
1278 * resultCount parameter to Sort Response (Amendment 1).
1279 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1281 Support for SRW 1.0 over HTTP. This is an optional feature and
1282 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1285 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1286 on the same port. SRW SearchRetrieveRequests are mapped
1287 to bend_init,bend_search,bend_fetch,bend_close.
1289 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1291 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1292 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1294 ZOOM connections are SRW based if schem http is used for hostname
1295 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1296 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1298 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1299 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1300 distance=n, order=true/false, relation=le, prox unit=word. If
1301 n is omitted, distance 1 is used.
1303 Fixed problem with C compiler include path in wrong order.
1305 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1306 on Solaris. Patch from Ko van der Sloot.
1308 New MARC decode API. All new functions operate on a yaz_marc_t
1309 handle. The most important new functions are: yaz_marc_create,
1310 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1311 decode and destroy respectively. Decoder can produce formats
1312 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1313 include/yaz/marcdisp.h.
1315 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1316 to UTF-8, UCS-32, wchar_t or Latin-1.
1318 * Prototypes for yaz_iconv_-functions moved to separate header
1319 include/yaz/yaz-iconv.h.
1321 Make a few private functions 'static' in unix.c. This prevents
1322 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1324 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1325 are set when Init Response is received.
1327 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1328 but returns diagnostic set as well.
1330 New function yaz_strerror which is a portable wrapper for
1331 strerror/strerror_r/GetLastMessage.
1333 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1334 is returned for MARC. If type is "oai", then OAI MARC is returned.
1336 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1339 --- 1.9.2 2002/11/26
1341 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1343 Fix bad race conditions on SIGTERM and terminate gracefully in
1346 Move retrieval (data1) module to Zebra since nobody seems to be
1349 Add GRS-1 render for ZOOM using same format as yaz-client.
1351 --- 1.9.1 2002/10/05
1353 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1355 Fix broken ESpec handling in data1 module.
1357 SGML reader parses comments and makes them part of the data1 tree.
1359 Added several type casts so that YAZ compiles as C++ code.
1361 ZOOM didn't handle PDU encoding failures properly.
1363 Added more Bib-1 diagnostics (approved extensions).
1365 GNU configure: better check for iconv.
1367 More portable use of accept, getpeername. Check for socklen_t. Use
1368 int/size_t if socklen_t is not defined.
1372 PQF parser rejects bad queries - including those with extra
1373 characters in them. PQF parser used to silently ignore that.
1374 Cleaner API for PQF added, which allows you to get detailed
1375 error information for bad queries (see yaz/pquery.h).
1377 Fixed bug in ZOOM_record_get for type "database".
1379 Implemented mini iconv library supporting conversions between
1380 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1382 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1384 --- 1.8.9 2002/08/20
1386 Fixed ZOOM C record cache so that preferredRecordSyntax and
1387 elementSetName is used to check for already fetched records.
1389 --- 1.8.8 2002/08/02
1391 Added three members in bend_initrequest structure to facilitate
1392 character set negotiation.
1394 Fixed a bug in frontend server that could cause indefinite
1395 loops under rare conditions.
1397 Revised character set utilities (charneg.h) so that encoding
1398 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1400 For PQF, directive @term <type> sets term type for Scan/Search.
1401 Here <type> is general, string, numeric, null. The term type
1402 is inherited - just like @attr.
1404 New call odr_set_charset that sets character set conversion for
1405 international-strings on a ODR stream. Prototype is:
1406 int odr_set_charset(ODR o, const char *to, const char *from);
1407 The InternationalString is still represented as C string in YAZ
1408 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1409 won't). On the protocol level, you can use any encoding.
1411 Support for UNIX sockets in ZOOM.
1413 Solaris recv sometimes returns errno == ENOENT. It is treated as
1414 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1416 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1417 both client and server. Code by Morten Bøgeskov.
1419 --- 1.8.7 2002/05/22
1421 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1422 that they can be used directly from Visual Basic. You must recompile
1423 your windows APP if you're using ZOOM.
1425 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1426 Commands "lang" and "charset" sets language and character set respectively.
1427 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1428 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1430 Attributes from multiple CCL fields may be OR'ed rather than merged
1431 using directive "@field or". Fields are still merged by default -
1432 equivalent to "@field merge".
1434 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1437 Fixed bug in zget for parameter ExtendedServicesResponse.
1441 --- 1.8.6 2002/03/25
1443 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1445 Client displays USR.1:SearchResult-1 (hits per term).
1447 Additional Search Info for search in Generic Frontend Server.
1449 Fixed CCL parsing of "field=s".
1451 WIN32 installer - using the excellent NSIS software from nullsoft.
1453 Fixed CCL parsing of "field = - <number>".
1455 Added function yaz_marc_decode that decodes MARC for line mode
1456 display or XML (similar to that used by JZKit).
1458 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1459 Z39.50. But ISO/ILL was, however.
1461 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1462 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1464 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1465 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1467 --- 1.8.5 2002/02/03
1469 New YAZ client features: Command completion and new commands:
1470 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1471 Code provided by Jacob Poulsen.
1473 New call oid_trav, that visits all registered OIDs via callback.
1475 Function ZOOM_record_get now returns const char pointer rather than
1476 void pointer. It saves a lot of type casts.
1478 For YAZ client, command "auth" now allows you to set authentication
1479 in IdPass style. It is enabled when three tokens are given - order
1480 is user, group and password.
1482 Fix memory leaks in MARC record handling for ZOOM.
1484 New option for YAZ client, -k <kilobytes> that sets
1485 maximum record size. Similar to -k option for generic frontend
1486 server and yaz-ztest.
1488 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1490 Prefix query parser reports "fail" when bad attribute set is given.
1492 Fix in MARC decoder. Proximity logging. Fix for attribute set
1493 in scan handler for server. Patches by Shigeru Ishida.
1495 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1498 Configure option --with-openssl=<dir> now works when a directory is
1499 specified. Patch provided by Morten Bøgeskov.
1501 New option for YAZ client, -u <auth>, that sets authentication.
1503 ZOOM fix: error information was sometimes "missing", since error
1504 was cleared/reset too when it shouldn't.
1506 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1508 --- 1.8.4 2002/01/04
1510 Scan for ZOOM API. New object ZOOM_scanset. New functions
1511 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1512 ZOOM_scanset_destroy.
1514 New ZOOM function, ZOOM_connection_last_event, that returns type
1515 of last event (such as "receive data", "send data", "apdu received",
1518 New ZOOM option, schema, that specifies schema for retrieval.
1520 New CCL feature. Qualifiers can be aliases for one or more
1521 other qualifiers (if more than one is given, OR is used).
1523 ZOOM uses named result sets if target supports it.
1525 Two new YAZ client commands: . (dot, which sources a script of YAZ
1526 client commands), and ! (to execute shell command.). Implemented
1529 Working on Debian packages.
1531 --- 1.8.3 2001/11/19
1533 YAZ client enables named result sets only if target supports it.
1535 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1537 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1538 with key="host" to get same result.
1540 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1541 Function Z3950_resultset_record(s) returns references to records
1542 "owned" by resultset. To become owner use Z3950_record_clone.
1544 Function z_ext_record handles Extended Services. Thanks to
1547 --- 1.8.2 2001/11/12
1549 CCL Parser fix: ignore token comma when dealing with and-lists.
1551 Documentation updates for COMSTACK.
1553 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1554 Changed prototype Z3950_records. For some functions, int parameters
1555 were changed to size_t.
1557 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1560 New MARC decode/display function, marc_display_exl, which properly rejects
1561 non-ISO2709 records. YAZ client uses it.
1563 --- 1.8.1 2001/10/29
1565 Fix bug: local attribute set wasn't set correctly in PQF strings.
1569 * Old Z39.50 codecs no longer supported.
1571 Added ZOOM C binding. See http://zoom.z3950.org/
1573 Renamed states for COMSTACKs to avoid confusion with events.
1575 Implemented cs_look and proper cs_rcvconnect.
1577 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1579 Configure detects POSIX threads on OpenBSD.
1581 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1582 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1584 When error is returned from present handler, non-surrogate diagnostic
1585 is returned in present response (and fetch handler is no longer called).
1587 * Minor adjustments to pquery parser (PQF). Token characters may be
1588 escaped by using backslash (C-style).
1590 PQF parser allows string attribute values to be specified. For @attr,
1591 non-numeric characters after the equal-sign are treated as strings
1592 (e.g. @attr 9=title).
1594 CCL trunction character may be defined (@truncation in file)
1596 * function zget_ExtendedServicesRequest sets waitAction to
1597 waitIfPossible (was wait).
1599 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1602 CCL operator names may be set in field definition files (CCL_bibset).
1603 See ccl/bib1 for an example.
1605 Fixes in ASN.1 compiler for C++ compatibility.
1607 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1608 and "op_or" to avoid conflict with C++.
1610 Fixed problem with GNU readline detection on Redhat 7.0.
1612 Added step-size for Scan backend handler.
1614 Fixed bug that made the frontend server crash when no attribute
1615 set was specified for scan.
1617 Front-end server automatically switches to original working directory
1618 when installed as an NT service. Previously -w had to be specified to
1621 Added extended attributes for retrieval module (data1), so that data1
1622 records carry d1_readXML/SGML attributes. d1_read also supports
1623 null-data rules ( <tag/>)
1625 On UNIX when POSIX threads are available, a separate library libyazthread
1626 is created. Programmers should link with that library and the yaz library
1627 when using threads. The reason for the split was that some applications
1628 on Linux, such as Apache, doesn't work well when using shared objects that
1631 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1632 (or any frontend server) in SSL mode by specifying ssl: followed by
1633 address. Only tested on UNIX.
1635 Added feature for CCL module. Virtual structure s=al or s=ol generates
1636 and-list and or-list respectively instead of phrase search.
1640 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1641 log_mask_str. This was done to avoid name conflicts with other libraries
1642 (such as other PHP extensions).
1644 Added raw OID member for preferred record syntax (request_format_raw)
1645 and returned record syntax (output_format_raw) for backend fetch method.
1647 Config file yaz-config now accepts options so that it returns specific
1648 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1650 Shared library support for UNIX using GNU libtool.
1652 * Modified backend interface. Request/Response struct's replaced by
1653 one read/write C struct. For example bend_fetchrequest and
1654 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1655 Every handler - even search has to be registered in bend_init
1656 handler. This means that the YAZ library no longer refers to
1657 external functions and it makes it possible to make the whole
1658 thing a single DLL/SO.
1660 Added Segment handler for backend server.
1662 Added Zmbol/Zebra administrative functions to YAZ client.
1664 Threaded frontend server on UNIX (when POSIX Threads are available).
1665 Starting the server with option -T enables multi-threading.
1669 Added configure option --enable-comp/disable-comp to control use
1670 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1671 located in sub directory asn.
1673 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1674 in ${exec_prefix}/bin along with the other programs yaz-client and
1677 GNU automake used to maintain makefiles.
1679 Added several OID's.
1681 Changed retrieval module so that we can load records with no abstract
1682 syntax defined. Tagpaths in these records are fully composed of string
1685 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1689 On UNIX, the generated makefile now supports a proper 'make install'.
1690 The prefix can be set via GNU configure to set the install location
1691 (default is /usr/local).
1693 * YAZ programs client and ztest were renamed to yaz-client and
1694 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1695 locations, such as /usr/bin,/usr/local/bin,etc.
1697 * YAZ Header files were moved from include to include/yaz. YAZ Header
1698 files are referred to as include <yaz/log.h> rather than <log.h>.
1699 The YAZ include path (-I ..) is therefore the same as before. Programmers
1700 should update their #include statements or use -Ipath/include/yaz
1701 instead. The main motivation for doing this change is that YAZ header files
1702 can be installed in "standard" locations /usr/include,/usr/local/include
1703 without introducing conflicts, since ALL YAZ header files are stored
1704 in subdirectory yaz (under /usr/include for example).
1706 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1707 rather than project/workspace files. We switched because project files
1708 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1711 Changed name of logging function, logf, to yaz_log, to prevent name
1712 clash with some math-log functions. The YAZ header log.h defines logf
1713 to yaz_log (#define) so there should be no incompatibilities by this
1716 Added bend_start/bend_stop handlers for server. These handler are
1717 called on start/stop of server. For windows they are called whenever
1718 a service is started/stopped.
1720 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1721 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1722 in util/yc.tcl. The auto-generated C code structures are, in a few
1723 cases, incompatible with the old decoders. There are differences in the
1724 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1725 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1726 The preprocessor variable ASN_COMPILED is defined when the compiled
1727 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1728 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1729 wish to use the old encoders/decoders you can specify --disable-yc
1732 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1733 version so that it supports both new - and old version of DB Update
1735 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1736 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1737 change. The name parameter can be set to 0 in which no name is specified
1738 for the construction. The macros odr_implicit and odr_explicit sets name
1739 parameter to zero for the construction involved. New macros
1740 odr_implicit_tag and odr_explicit_tag are similar to the others,
1741 except that a name parameter is added. For programmers' that don't use
1742 ODR they probably only need to change the call to z_APDU and z_External.
1744 Added access control facility by interfacing the TCP wrapper library.
1745 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1746 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1747 name of the daemon and enables the access control as specified in
1748 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1750 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1751 den Dool <H.M.vdnDool@kub.nl>.
1753 Added reference ID parameter to most functions in server API - refer
1754 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1756 Changed name of ccl library to libccl.a (was ccl.a).
1758 Fixed bug in decoder for Explain (Category TargetInfo).
1760 Added support for GNU readline in client. Thanks to Jacob Poulsen
1761 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1763 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1764 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1765 IMPLEMENTATION! This change was made to the development version before
1766 the ZIG decided to retract the amendment. If any users MUST be
1767 compatible with the original Update definition, PLEASE CONTACT US, and
1768 we will include a separate definition corresponding to the old Update
1769 ES. Note that because of the change to the ASN.1 of the
1770 TaskPackageRecordStructure we cannot define a single structure that
1771 will support both versions.
1773 * Added const modifier to buffer parameter for some ODR/BER encoding
1774 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1775 completeWAIS, odr_dumpBER.
1777 Fixed bug in client.c which caused a crash when a scanResponse didn't
1778 contain positionOfTerm.
1780 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1781 * will cause an error in a client if a non-YAZ target sends both a
1782 * list of Scan entries and non-surrogate diagnostics.
1784 Retrieval module enhancements. Tag sets may be typed in the reference
1785 to it. From the .abs-file the "tagset" directive takes a third optional
1786 integer type for the tag set referenced. From a .tag-file the "include"
1787 directive takes a third optional type as well. The old "type" directive
1788 in the tag set itself is still recognized but acts as the default type
1791 Backend interface change. Individual Scan terms returned from bend_scan
1792 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1793 in include/backend.h.
1795 Retrieval module enhancements. Multiple tag sets and attribute sets may
1796 be specified in abstract syntax specs. Revised the error/warning for
1797 logging messages reported by the retrieval module when reading the
1800 Object Identifier system (oid_..) changed. The API is backwards
1801 compatible but the oid-routines now allocates new OID's when needed.
1802 Raw OID's may be specified in oid_getvalbyname.
1804 YAZ now uses GNU configure to generate Makefile(s).
1806 * Minor changes in some of the member names of DeleteResultSetRequest and
1807 DeleteResultSetResponse. See include/proto.h.
1809 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1810 and added member 'languages' in TargetInfo (which was missing).
1812 Changed the way attribute sets are handled in the retrieval
1813 module. These are now cached, just like the abstract syntaxes
1816 Changed YAZ so that it links with compiled ASN.1.
1818 Added Explain-schema definitions and mapping routines. The following
1819 Explain categories have been implemented: AttributeDetails,
1820 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1822 Fixed minor bug in Windows version of Server Library.
1824 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1826 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1828 Added EXTERNAL: UNIverse Resource Report (non-standard).
1830 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1831 ENUMERATED and SET OF.
1833 * Added 'const' to some of the char pointer arguments for the
1834 functions, data1_read_node, data1_getelementbytagname,
1835 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1838 Fixed bug in data1_insert_taggeddata - the last_child member of
1839 parent wasn't initialised.
1841 * Changed data1_read_record and data1_read_node so that the supplied
1842 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1843 doesn't refer to any parts of the "SGML"-buffer.
1845 Fixed bug in server library (Windows version of statserv_remove).
1847 * Changed code so that it compiles as C++. The type definition
1848 of Odr_fun which is a member of Odr_arm was changed. The result is,
1849 that an explicit typecast is needed for the fun pointer when
1850 using Odr_arm - as in:
1851 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1853 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1855 Implemented the new structured date and time definition as approved
1856 by the ZIG. Added schemaId element to the specificTag in Espec-1
1857 (also approved at the last ZIG). Thanks to RVDM.
1859 Added some Object identifiers (RVDM).
1861 Changed the Update Extended Service (RVDM).
1863 Added command "refid" to client which specifies referenceId for
1864 the following requests.
1866 Implemented extended service handling for server. See ztest.c
1867 for an example as well as backend.h. New handlers are registerd
1868 in the Init handler.
1870 * Changed interface for sort in server.
1872 Added new members to statserv_options_block. It allows a server
1873 to read options from another source than just the command line. Thanks
1874 to Charles Woodfield.
1876 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1877 renamed to zboolean. Some C++ compilers complained about the name.
1879 Minor changes to gils.abs. Added index 's' (sort) on title
1880 and date/time-last-modified.
1882 --- 1.4pl2 1998/1/30
1884 Fixed bug in server library regarding inetd mode (-i). This bug
1885 was introduced by release 1.4.
1887 --- 1.4pl1 1998/1/29
1889 Added sort facility in client and backend server interface.
1891 Fixed problem with dependencies in Makefile(s).
1893 Fixed bugs for encoders/decoders of extended services and
1896 Implemented sub-tree feature for schemas. Sub-trees are
1897 referenced in *.abs-files. See explain.abs for an example
1898 of the use of this feature.
1900 Modified bib1.att; local attributes for ANY didn't include
1901 ANY itself (only affects use of the retrieval module).
1903 Fixed bug in plain SGML reader in function data1_read_node:
1904 tags with prefix "var" was incorrectly interpreted as variants.
1906 Added feature "sub-schemas" to enable references to - and definitions
1907 of - group of elements.
1909 * Removed member parent from type data1_element (in data1.h).
1911 Implemented function odr_nullval() that returns the value of
1914 * Removed member num_children from data1_node (in data1.h).
1916 Made NT service interface part of the server library. The
1917 function statserv_main uses the NT service when required and
1918 calls the statserv_start / statserv_close routines.
1920 Routine zget_SearchRequest and zget_PresentRequest fills
1921 resultSetName/Id member with "default" instead of "Default".
1923 Fixed memory leak in server. Request queue member wasn't freed.
1925 Fixed nmem_exit so that memory is freed.
1929 Revised the CCL parser utility to be thread safe.
1931 Added function, oid_ent_to_oid, to replace the function
1932 oid_getoidbyent, which is not thread safe.
1934 * Added nmem_init and nmem_exit to initialize and release
1935 NMEM resources. Function nmem_init should be called once in the
1936 initial thread before NMEM/ODR is used. statserv.c and client.c
1937 have been changed accordingly. The change was necessary to make
1938 NMEM thread safe. The NMEM memory pool is shared amongst threads
1939 in a process. Unix-based applications will still work fine without
1942 Added NT Services interface for the the Z39.50 (statserv) Server.
1943 Refer to the ztest.c source on the usage.
1945 Windows 95/NT port using MSVC5.0. Project files are included in the
1948 * Defined new 'global' handle for the retrieval (data1) system. The
1949 new handled, data1_handle, describes the state of the data1 system.
1950 This handle is passed as first argument to virtually all
1951 data1 related routines. The functions data1_create and data1_destroy
1952 creates and destroys a data1 handle respectively.
1954 Added ODR encode stream member to all backend request structures
1955 init, search, scan etc. This stream should be used to allocate all
1956 memory used for the response when thread safe operation is needed.
1958 Changed the comstack utility, cs_addstr, to be thread safe. The
1959 returned hostname string returned by the function is now part the
1962 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1963 function. The cs_straddr takes a COMSTACK handle as argument, so this
1964 function must be used after cs_create and before bind/connect.
1965 This function is thread safe.
1967 Moved test server to 'ztest' directory - generic server code still
1968 in 'server' directory.
1970 Made prefix query (pquery.c) utility thread safe.
1972 Added new function modifier YAZ_EXPORT to 'export' public DLL
1973 functions when using windows (see include/yconfig.h).
1975 Added definitions to the OID database (util/oid.c) (RVDM).
1977 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1979 Added call to ccl_rpn_delete in client program.
1981 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1982 release of RPN structure.
1984 Added support for C++, headers uses extern "C" for public definitions.
1985 With input from RVDM.
1987 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1988 Thanks to Ronald van der Meer (RVDM).
1990 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1992 Added support for private extensions to the OID database
1993 (oid_setprivateoids()). Thanks to RVDM.
1995 Added optional, physical ANY (key replication)
1997 Fixed null-reference problem in GRS-1 output filter.
1999 Proximity operator added to Prefix Query Format (PQF).
2001 In test client command "base" accepts multiple databases.
2003 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2007 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2009 Smallish bug-fixes in the new encoders/decoders (explain).
2011 Bug fixed in DeleteRequest.
2013 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2015 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2017 Added SOIF syntax (using private OID for now) to retrieval module and client.
2019 Added Update extended service.
2021 Added SearchResult-1 additional info structure.
2023 Added optional CCL (ISO8777) interpreter as separate module. Available
2026 --- 1.2 1996/6/10 (1st anniversary release)
2028 Added Summary record syntax. Lightly tested.
2030 Added OPAC record syntax. Untested.
2032 Added ResourceReport service encoders/decoders. Untested.
2034 Fixed bug in z_Unit - wrong tagging on unitSystem.
2036 Fixed bug in the DiagRecs decoder.
2038 Added options for max PDU size and session timeout to frontend-server.
2040 Added documentation of query-language parsers and other supporting utilities.
2042 [frontend-server] Added Attribute set to the bend_scanrequest API.
2044 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2045 surrogate diagnostics were generated.
2047 [retrieval] Allow multiple local values for attribute.
2049 [retrieval] Allow multiple attributes per element in .abs files. index type.
2051 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2053 --- 1.1pl2 1996/4/10
2055 Minor changes, mostly specific to Zebra's requirements (retrieval)
2059 Repaired bug in frontend server when running multiple listening
2060 endpoints in dynamic mode.
2062 z_External() now won't break if a known, ASN.1 value comes encapsulated
2063 in an octet-string. The value will pass through unmodified in an Odr_oct.
2065 Added a bit of code to the demo client to decode & display
2066 ASN.1-structured records represented in the octet-aligned branch of
2067 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2069 Added z_ext_getentbyref() to the ASN module. Doc updated.
2071 * Completed the SCAN definition in the ASN module. This may break SCAN
2072 code based on older YAZ-versions at compile-time. The fix is easy -
2075 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2076 under the SCAN definition. Remember to initialize this, server-people.
2078 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2079 that this does not extend to ODR and ASN.
2081 Comstack allows insertion of established socket (primarily for
2082 inetd-operation of servers). Doc updated.
2084 Front-end server can now start from the inetd in TCP mode. Doc
2087 --- 1.0pl4 1996/1/24
2091 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2092 the rank and record number.
2094 Adjustments to the frontend server.
2096 Fixed diagnostic BER dumper. It ignored the file argument.
2100 Various changes to retrieval module.
2102 Changed the union discriminators of the protocol files from enums to
2103 ints paired with #defines.
2105 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2108 *Changed operator in the RPN structure to 'roperator', again to avoid a
2111 Fixed problems in Explain decoders/encoders.
2113 --- 1.0pl2 1995/12/6
2115 Memory bug in log module fixed.
2117 --- 1.0pl1 1995/12/5
2119 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2121 Bug in Explain DatabaseInfo module fixed.
2123 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2127 The shift to v1.0 signals that we now consider the *core* functionality
2128 of YAZ reasonably stable (the core being more or less equivalent to
2129 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2130 tested (Explain not at all - though that will happen soonish).
2132 Minor changes to code to support Windows port.
2134 Various minor changes after we're getting to use GRS-1 & co. more.
2136 Added Espec-1 format.
2138 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2139 of the protocol and it cannot be selected when encoding (maps into 'string'
2140 when decoding). Needed to talk to some servers.
2142 Demo client can request simple element set names.
2144 Added Diagnostic Format encoders/decoders.
2146 Added simple Close handling to frontend server (no hooks for resource
2147 reporting yet), and demonstration client.
2149 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2151 --- 1.0b3 1995/08/24
2153 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2154 handled incorrectly when records were requested in the searchResponse. This
2155 will only affect you if you use the frontend-server.
2157 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2158 Test-client will ask for and print GRS1. Ztest will return dummy records
2161 Added Explain encoders/decoders to the service-level API. Untested.
2163 Added Extended Services: Item Order encoders and decoders to the Service-
2164 level API. Untested. We could use a recent copy of the pertinent bits
2165 of the ILL protocol to add those bits.
2167 Added diagnostic format 1 encoders/decoders to the service-level API.
2170 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2171 odr_cons.c, which causes a more correct output.
2173 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2174 was always set to 0 when no records were requested in the searchRequest.
2176 * Added better external-handling. This shouldn't harm old code that
2177 *encodes* externals. It can break code that looks for a
2178 'single-ASN1-type' representation, since those types that are known
2179 are now decoded immediately. Look at the SUTRS sample code in
2180 seshigh.c and client.c. Documentation updated.
2182 Handling of structured records in bend_fetchresponse. Length -1 marks
2183 structured record, type is deduced from format field.
2185 --- 1.0b2 1995/06/27
2186 Fairly quick maintenance release to add SUTRS support.
2188 Fixed handling of SUTRS records in the demonstration client.
2190 * Added format field to the bend_fetchrequest and bend_fetchresponce
2191 structures of the backend API (frontend server). When the record is
2192 returned, the value of the format field is mapped to an OID. The
2193 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2194 of the record. The special value VAL_NONE in the bend_request means
2195 that no specific format was requested by the client. Documentation
2196 updated accordingly. Test server (ztest) will return a fixed dummy
2197 SUTRS record if your client requests SUTRS.
2199 Documentation updated accordingly.
2201 You can now set external libraries and RANLIB support in the top-level
2205 First public release.
