1 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2 libyaz.la is the core of YAZ except the generic frontend server and
3 does not depend on POSIX threads anymore. libyaz_server.la is the
4 generic frontend server facilities and uses POSIX thread functionality
5 if available. The libyaz.la no longer depends on POSIX threads because
6 the number of global structures is limited. NMEM no longer re-uses blocks
7 between threads ; it simply free's memory immediately but allocates in
8 "large" chunks as usual. We don't expect any performance penalties
9 because of this. The yaz_log system is still using a global log_level so
10 caution must be taken when modifying it with yaz_log_init_.. +
11 yaz_log_mask_str. This, however, should not cause any trouble because
12 these functions are called during initialization of application code
13 anyway. `yaz-config --libs server` returns libs for server applications;
14 `yaz-config --libs` returns libs for non-server applications.
16 New OID database - with public definitions in oid_db.h. Removed old OID
17 database including the head oid.h and definitions such as enum oid_value
18 and struct oident. The new OID database uses the same string names as
19 before but the 'protocol' is gone. There are now only two representations
20 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
21 converts from string to OID; functions with prefix yaz_oid_to_string
22 converts the other way.
24 Change to emit_term() in CQL-to-PQF query translation: when a term has
25 the /regexp relation modifier, do not process it for leading and
26 trailing "^" and "*", which have quite different meanings in regular
29 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
30 write handlers no longer carries a 'last' parameter. This will make
31 yaz_iconv flush "less" characters. A flush is performed by call to
32 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
34 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
35 removed, because function yaz_query_to_wrbuf does the same.
37 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
38 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
40 Deprecated MARC utility functions removed.
42 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
45 Branch split: YAZ_2_1_55_branch
49 Fix to ZOOM-C so that transparent reconnection is properly handled on
50 connections that are in asynchronous mode.
52 Fixed compilation on OpenBSD 4.0.
54 Large strings in GRS-1 records are now properly displayed in yaz-client.
56 Added character conversion support for "advancegreek"; based on patch from
59 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
60 sequence is met. Before the error was not set so it would be unknown.
62 Adjust yaz-marcdump MARC reader so that it skips until record separator
67 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
68 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
69 fd_set structure used as a bitmask for the FDs to be selected on.
71 Using ACX_PTHREAD macro to check for POSIX threads.
73 Fixed have-vsnprintf check.
77 Fixes for configure on BSD. Bug #900.
79 Added snprintf/vsnprintf wrappers for systems that don't have
80 limits (heavens forbid).
82 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
83 created before all previous tasks were completed and removed from the
84 task queue, the new task could be removed by a mistake.
86 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
88 Implemented pass-through CQL-to-PQF conversions. Bug #861.
90 Fixed bug #832: Problem with MARC/charset in yaz-client.
92 Fixed bug #668: save command line history for yaz-client.
94 Fixed bug #830: pkg-config support.
98 Extended ZOOM result set options with two options that may be read by
99 a client: resultSetStatus and presentStatus with values as specified for
101 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
103 Fixed bug #827: Using SSL fails on Debian etch.
105 Fixed bug #826: Weird looking chars for set of MARC records.
107 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
108 that is treated as an ItemOrder with itemRequest being an XML document
109 external. The value of "doc" is the content.
111 Extended the GFS search facility. New member of bend_search_rr
112 'estimated_hit_count' signals that hits is known to be an estmate
113 (higher or lower than real hit count). New member 'partial_resultset'
114 signals that the search was partial (hit count is lower or equal than
115 real hit count). For Z39.50, the information is stored in resultSetStatus
116 member of SearchResponse APDU. For SRU, the information is signalled
117 via SRU diagnostic 59: "Result set created with valid partial results
120 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
122 --- 2.1.46 2007/01/13
124 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
126 Added ZOOM_connection_peek_event.
128 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
129 the following new functions:
130 ZOOM_event_nonblock, ZOOM_connection_process,
131 ZOOM_connection_get_{socket,mask,timeout},
132 ZOOM_connection_fire_event_{timeout,socket}.
133 The existing blocking event handler, ZOOM_event, is a wrapper for the
134 + blocking ZOOM_event_sys_{poll,select}.
136 Implemented function ccl_xml_config which parses XML version of CCL
137 configuration (bug #798).
139 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
141 Added timings utility (yaz/timing.h)
143 --- 2.1.44 2007/01/03
145 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
148 Fixed bug #779: Rotation of apdu.log fails.
150 Fixed for character set conversions:
151 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
152 Honor G1 set in MARC-8 decoding.
154 --- 2.1.42 2006/12/17
156 Fixed bug #775: char conversion does not handle Alternative UTF-8
159 Implemented function yaz_marc_read_line which parses MARC line format
160 records. There is a wealth of formats out there. So far, this function
161 reads line records produced by yaz_marc_write_line.
163 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
164 more generic and easier to remember(!) options: -i format and -o format
165 which specifies input format and output format respectively - where
166 format is one of "marc", "marcxml", "line", "marcxchange".
168 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
169 does not print anything except warnings for records.
171 For yaz-marcdump, added support for MARC split into files (-s) with a given
174 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
175 spec, at http://www.loc.gov/standards/sru/record-update/
176 This has changed the binary layout of the following structs:
177 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
178 bend_update_rr . Patch by Ko van der Sloot.
180 Added GFS utility function bend_assoc_is_alive which returns 1 if
181 association is still alive (client is connected); 0 otherwise (client
182 closed connection). This allows busy servers to stop working for
185 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
186 been a separate piece of software. This version of ziffy has been modified
187 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
189 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
191 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
192 Client code may now interrogate options such as "init_opt_sort" to
193 find out whether the server claims to support various options.
195 --- 2.1.40 2006/11/27
197 Added utilities yaz_{set,get}_esn to set/get element set name from
200 Removed the build of libyazthread.la. The libyaz.so is the threaded version
201 of YAZ and has been so since YAZ 2.1.10.
203 Implemented ZOOM_record_error which returns error information for
204 record (surrogate diagnostic).
206 --- 2.1.38 2006/10/31
208 Updates for SRU Update by Ko van der Sloot:
209 1. Changed name from "operation" to "action"
210 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
211 versions in the code, marked as 'backward compatible'.
212 3. Added diagnostics for SRU Update.
214 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
216 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
218 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
220 For GFS, fixed problem with SRU diagnostic 'First record position out of
221 range' being issued for 0 hits.
223 zoomtst10 part of Windows Build.
225 --- 2.1.36 2006/10/13
227 Implemented yaz_filepath_comp which splits a path into file path
228 components (required by Zebra 2.0.3+).
230 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
231 BSD inspired license until now so this should not have any real impact on
232 anybody. See http://www.opensource.org/licenses/bsd-license.php
234 Fixed bug #687: Missing log lines.
236 Fixed bug #678: CQL to PQF translation does not preserve double-quote
239 Fixed bug #689: SRU diagnostics to be added.
241 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
242 whether a connection is idle (no more work do do).
244 --- 2.1.34 2006/10/04
246 Change type of optval from long to int for invocation of setsockopt with
247 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
249 Added support for specifying the max log file size for the Generic
250 Frontend Server. The size is given with option -r.
252 --- 2.1.32 2006/09/21
254 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
256 --- 2.1.30 2006/09/17
258 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
261 Fixed bug in Generic Frontend Server that could cause a server to stop
262 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
264 For the generic frontend server, the maximum record size is used as maximum
265 size of incoming packages (SRU + Z39.50). The value until was previously
266 only used in Z39.50 Init negotiation and, later, in a session controlled
267 sizes of records returned. This is controlled using -k option. It can be
268 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
270 --- 2.1.28 2006/09/04
272 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
275 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
277 New option for yaz-marcdump -lpos=value which allows setting a portion
278 of MARC header to a certain value.
280 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
282 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
283 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
285 --- 2.1.26 2006/08/15
287 Fixed problem with SRU mode type (soap, get, post) for yaz-client
290 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
292 --- 2.1.24 2006/08/08
294 Fixed MARC ISO2709 encoding routines to deal with character set
297 Minor changes to GFS logging. Database included in search request log
300 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
301 cached/multiple records.
303 Shared libraries are built by default on Unix+configure.
305 Changed cql2pqf transformation to use a different evaluation order. The
306 new order is: always, relation, structure, position, truncation, index
307 and relationModifier. Old order was: always, relation, relationModifier,
308 structure, index, position, truncation. Note that the the latter ones
309 override former ones for identical attributes.. The new scheme means that
310 it is possible to override any existing attribute with a relationModifier.
311 And also that it is possible to override everything for the index rule
312 (except the ones listed in relationModifier). No order is perfect but this
313 one, we believe, covers more real cases.. The "always" should have been
314 called "default", since the attributes there can be overridden with all
317 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
318 compilation phase, but also for yaz-config --cflags output. This allows
319 us to have public headers with Libxml2 stuff in them . It should also,
320 eventually, make Libxml2 checks redundant in packages using YAZ, such
323 --- 2.1.22 2006/06/15
325 Changed SRU update structure bend_update_rr so that SRU diagnostics are
326 stored in uri, message and details.. Previously diagnostics were stored
327 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
328 compatibility.. but he's probably the only one affected, so.
330 Added support for CCL, compiled on the client side, in ZOOM-C. This
331 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
332 input; the resulting query objects can be used for for searching with
333 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
335 YAZ' configure searches for OpenSSL by default.
337 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
338 SL_CTX_use_certificate_file. See
339 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
340 for more info. Thanks to Ko van der Sloot.
342 --- 2.1.20 2006/06/02
344 Bug #600: SRU GET, POST support for yaz-client. Introduced
345 command 'sru' which selects method SOAP/GET/POST.
347 Allow missingValueAction to be specified for the sortspec string -
348 function yaz_sort_spec. By default, the missing value action is null.
349 Use ! to specify "abort". Use = followed by stringvalue to specify default
352 Ensured that Present-handler (if defined) is called in GFS before any call to
353 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
354 searchRetrieve requests.
356 Documentation for YAZ is now based on the Docbook XML/XSLT using
357 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
358 is no longer depending on jade/openjade or docbook-to-man scripts.
359 PDF is no longer part of the distribution - but can optionally be
360 made using DSSSL/jadetex or FOP.
362 Added retrieval handling support in Generic Frontend Server to support
363 conversion between MARC/XML as well as XSLTtransforms. See
364 etc/yazgfs.xml for an example.
366 Added Authentication support to Generic Frontend Server in SRU
367 mode. Authentication using HTTP Basic is supported, as is the use
368 of 'x-username' and 'x-password' parameters in the request itself.
370 Added support for a new character set MARC8s identical to MARC8 except
371 that it converts combined characters to single Unicode characters in the
372 Latin-1 range (when possible).
374 --- 2.1.18 2006/04/24
376 ASN.1 compiler 0.4: generates brief Doxygen file header for
377 generated .h/.c files.
379 Utility yaz_iconv now supports conversion to MARC-8.
381 New facilities for the MARC module. The reading - and writing of
382 content are separate methods for the yaz_marc_t handle. The following
383 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
384 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
385 format). Write functions have prefix yaz_marc_write_.. The existing
386 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
387 available. Removed support for OAI-MARC and simplexml (not the
388 simplexml from PHP5).
390 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
391 to be returned for this connection.
393 --- 2.1.16 2006/03/31
395 Allow multiple languages and charsets to be specified with
396 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
397 negcharset iso-8859-1,utf-8
399 Translation of proximity nodes from CQL into PQF now works.
401 Moved to automake 1.8, 1.9.
403 Added function yaz_log_set_handler which allows a log handler to be
404 installed. This handler will be called for all log messages. Output
405 to file is also produced; but that can be disabled by passing NULL
406 fname to yaz_log_init_file.
408 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
410 For SRW (including GFS), accept application/soap+xml as content-type
413 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
414 produces NO stylesheet reference even if a default stylesheet is specified
417 --- 2.1.14 2006/03/14
419 Updated Windows package to include yazd.dll + yazd.lib for the
420 Development component.
422 If the environment variable YAZ_LOG is set, then it is used as a
423 string indicating the default level of logging to use if not
424 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
425 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
426 used as before. So, for example, to omit warnings from YAZ logging,
429 cql_transform() now map structure and other attributes before indexes,
430 so that index-specific structures and other attributes can override
431 defaults. So now a combination of mapping specifications such as:
433 index.dc.date = 1=date-modified 4=5
434 does the right thing.
436 cql_transform() now also respects the "always" mapping specification,
437 which establishes an initial set of attributes to be used for all
438 terms except where overridden by more specific attributes associated
439 with the index, relation or modifier.
441 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
442 which mode to use; one of "post", "get" or "soap" (SRW, default).
444 Fixes for yaz_iconv routines: changed trie-based character set conversions
445 to use only non-negative values for bit fields due to Sun's C compiler not
446 supporting negative values.
448 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
449 sequences where not read correctly. Fix by Rustam Usmanov.
451 Updated win/makefile to use options, settings which makes things
452 compile with VS C 2005.
454 --- 2.1.12 2006/02/01
456 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
458 In ZOOM socket code, use select instead of poll on MacOSX.
460 ZOOM-C now support client-side compilation of CQL into RPN that is
461 sent to the server, enabling CQL to be used against all Z39.50
462 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
463 ZOOM_query object, and submit it using ZOOM_connection_search().
464 The CQL-to-RPN translation uses a configuration file, the name of
465 which must be specified in the Connection's "cqlfile" option.
467 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
468 function, which takes as its start-term parameter a ZOOM_query object
469 (which may have had either CQL or RPN set into it).
472 --- 2.1.10 2005/11/29
474 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
475 GFS to support this as well. Backend handler, bend_srw_update, does the
476 update work. Code contributed by Ko van der Sloot.
478 Allow retrieval of Search Result-1 information in ZOOM by the use of
479 options that are attached to a result set. ZOOM documentation updated
482 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
483 UTF-8 conversion. Patch by Raj Patel.
485 Added option -m to GFS to control formatting of timestamps in log file.
487 Added 'exit' as synonym for 'quit' in yaz-client
489 Added support for specifying SRW resultSetId + resultSetIdleTime in a
490 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
491 for the new members. Patch by Ko van der Sloot.
493 Added support for SRU POST. It is supported for content-type
494 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
496 Do not build the separate Multi-threaded (MT) library libyazthread.la.
497 Instead make the library libyaz.la multi-threaded. Threading as a whole
498 can still be disabled by configure option --disable-threads. Previosly,
499 with older GLIBCs there were problems with MT libs under Apache. This
500 has now been fixed a long time ago.
502 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
505 CQL module modified to be case insensitive for relations/indexes/operations.
507 Fixed bug in CQL transform code: incorrect value relationModifieder
510 Added 'show all' command for yaz-client which retrieves all results
513 Added new yaz-client, xmles, which takes a (private) OID and
514 a document to be sent as an extended service request.
516 Describe new yaz-client commands wait_response and set_auto_wait.
518 Increase TCP/IP listener backlog from 3 (which I am guessing was
519 copied from the SunOS manual entry way back when) so SOMAXCONN, so
520 that the socket will queue as many incoming connections as it's able
521 to handle ongoing connections. In other words, it will never now
522 refuse a connection that it would be able to handle merely because
523 it's not got around to accepting() enough of the pending connections
524 yet. This is the behaviour anyway under Linux, where the listen()
525 argument is ignored; but not under BSD and on systems such as
526 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
527 YAZ-based servers should now be uniform across operating systems in
530 yaz-marcdump uses 64-bit file access on some systems. This is enabled
531 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
532 This allows yaz-marcdump to read large MARC batches (>2 GB).
534 Modified all YAZ source files - except the source which is auto-generated
535 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
538 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
539 corresponding to the existing *_setl() function. These allow option
540 values containing arbitrary valuues.
542 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
543 ZOOM_resultset_sort() in new applications. Its behaviour is identical
544 except that it returns an indicator of whether or not the sort
545 criterion was accepted (0 for OK, -1 for invalid).
549 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
550 MARC output rather than returning "new" buffer.
552 yaz-client warns about unknown init options.
554 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
558 Added support for SRW sort in Generic Frontend Server. Patch
559 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
560 sortKeys - or NULL if none is provided.
562 Fixed bug #307: It was impossible to specify indefinite/no timeout
563 for ZOOM_event. Special timeout value -1 now means indefinite timeout
566 Added support for multiple languages and charsets to be specified in
567 ZOOM. Each charset/language is separated by a blank. If negotiation is
568 in effect in init-response, Option
569 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
570 Code based on patch by Vasiliy Osadchuk.
572 Fixed bug #306: infinite recursion that occurred when calling
573 yaz_log_level_init as the first call (before other log level or
576 Fixed bug in scan handling in front end server: if preferred-Position-In-
577 Response was non-present, a NULL pointer referece was performed.
581 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
582 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
583 now defined for all those error codes. So instead of putting 109 in
584 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
585 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
587 Modified the yaz-marcdump utility to skip garbage bytes between MARC
590 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
592 Program yaz-client now exits and produces an error message if multiple
593 Z39.50 servers are specified on the command line (none or one allowed
596 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
601 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
603 Fixed bug #272: Preserve spacing for CCL terms.
607 Added support for virtual hosts and multiple backend servers for
608 the YAZ frontend server. The configution is XML based and
609 support specificition of CQL to RPN mappings and explain information.
610 See section "Virtual Hosts" in the YAZ manual.
612 Extended OPAC display utility. OPAC display utility renders
613 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
614 to supplement yaz_marc_decode_wrbuf.
616 Fixed a bug in MARC decoder that could caused it to crash for some
617 invalid MARC records. More diagnostics and warnings where added in
618 XML output (warnings, etc are stored in comments).
620 --- 2.0.34 2005/02/08
622 Fixes for UNIX domain sockets. Bug #261.
624 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
626 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
627 Added yaz_marc_subfield_str which defines subfield lead string which is
628 used in YAZ_MARC_LINE format. Default string is blank+$. Added
629 yaz_marc_endline_str which defines end of fields string used in
630 YAZ_MARC_LINE format. Default string is newline.
632 Experimental support for MarcXChange. This format can be produced
633 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
634 http://www.bs.dk/standards/MarcXchange.xsd
636 Added yaz-client commands scansize that sets maximum number of
637 entries to be returned by scan.
639 --- 2.0.32 2005/01/11
641 Added support for SRW scan in yaz-client and Generic Frontend Server.
643 * Added whereInList member to SRW Scan Term.
645 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
647 Fixed NMEM system to return aligned blocks on the smallest boundaries
648 that are suitably aligned for all possible types on the particular
649 architecture YAZ is being built for.
651 --- 2.0.30 2005/01/04
653 Fixed numerious warnings that was issued with newer versions of GCC.
655 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
656 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
659 Make YAZ Generic Frontend Server slightly faster.
661 Enhance (and reduce) logging for Generic Frontend Server.
663 Revert YAZ log system so that it flushes every write operation
664 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
666 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
667 instead of LOG_, due to name clash with syslog(3). LOG_ are still
668 present. New applications should define YAZ_USE_NEW_LOG=1 - this
669 will effectively disable old definitions.
671 --- 2.0.28 2004/11/09
673 Added yaz_log_time_format which specifies log format using
676 Added yaz_log_module_level which returns mask for a module. Value
677 is non-zero mask a if module is enabled; zero if disabled.
679 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
680 in include/yaz/cql.h.
682 Fixed bug #176: Dont throw diagnostics on empty SRU args.
684 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
686 Fixed bug #172: RPM builds does not enable SSL.
688 Doxyfile.in part of dist. Doxyfile generated by configure.
690 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
691 are given and the corresponding component does not exist.
693 Extend CCL documentation in YAZ reference. Describe r=r.
695 --- 2.0.26 2004/10/01
697 Fixed MARC->MARCXML conversion to properly deal with
698 fields, subfields, indicators having non-ASCII characters.
700 Fixed MARC->MARCXML conversion so that ASCII control characters
701 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
704 Added YAZ GFS support for conversion from Z39.50 surrogate
705 diagnostics to SRW surrogate diagnostics.
707 Bug fix: YAZ GFS did not return schema in explainResponse.
709 --- 2.0.25 2004/09/30
711 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
712 now converts recordSchema to elementSetName as well as schema URI.
714 Fixed bug in COMSTACK that prevented HTTP request packages from being
717 --- 2.0.24 2004/09/29
719 Added CCL facility r=r "range" which is similar to r=o "ordered" but
720 does not require white-space before and after the dash in a range, e.g.
721 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
724 Fixed a few AC_TRY_LINK configure tests that did not operate properly
725 due to new GCC removing "redundant" code.
727 Added yaz-client commands scanpos and scanstep that sets preferred
728 position and step-size for scan.
730 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
732 Added CCL utility ccl_qual_buf which parses one or more CCL
733 spec lines in a buffer.
735 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
736 of name and value - ignoring empty lines and comments.
738 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
740 Added odr_get_element_path which returns current element path for an
741 ODR handle. This utility is useful in error handling or user-defined
744 Added ODR_PRINT utility odr_set_stream which is is a more generic
745 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
746 to a write function and pointer to close function. The close function - if
747 non-NULL - will be called during odr_destroy.
749 Fixed bug in CCL parser where truncation char was not removed from
750 right side when truncation=both was in effect.
752 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
755 --- 2.0.23 2004/08/11
757 Fix buffer overrun in CQL parser when dealing with proximity (%).
759 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
760 to UTF-8/UCS conversion is now only based on codetables.xml.
762 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
764 --- 2.0.22 2004/08/06
766 Add support for more "commit changes" in ZOOM (uses Extended Services).
768 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
771 Yet another small fix for configure of SSL.
773 --- 2.0.21 2004/05/14
775 Fix SSL libs for configure when --with-openssl=DIR is given.
777 --- 2.0.20 2004/05/10
779 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
781 SSL comstack now uses yaz.pem certificate file on server side
782 by default. Certificate filename can be configured by calling
783 comstack function cs_set_ssl_certificate_file before cs_bind is used.
785 Fix bug regarding multiple calls to ZOOM_connection_connect.
787 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
789 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
790 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
792 ZOOM now allows inspection of X509 peer certificate for verification.
793 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
795 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
796 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
797 as "modular" but it simplifies things.
799 Added cs_get_peer_certificate to that returns peer X509 PEM.
801 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
802 NULL if SSL is unavailable.
804 Documentation about MARC decoding tools.
806 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
808 --- 2.0.19 2004/03/30
810 Rename CHANGELOG to NEWS to follow GNU style packing.
812 Fix bug with missing initialization of member in init_diagnostics.
813 This bug affects threaded version of GFS server.
815 --- 2.0.18 2004/03/20
817 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
820 Ensure zlib.dll is packed with Windows install.
822 --- 2.0.17 2004/03/17
824 Fix encoding of xsd:string to use text instead of CDATA.
826 Fix endless loop in CQL parser with unbalanced ".
828 Use a more compact way to store MARC-8 conversion tables.
830 --- 2.0.16 2004/03/16 Debian only
832 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
835 Update CQL parser to use new CQL 1.1 modifiers for booleans and
840 --- 2.0.15 2004/03/01
842 Another fix for decoding of XML packed records.
844 --- 2.0.14 2004/02/25
846 Fixes for Chunked encoding. White space not ignored after length spec.
848 Update NS and use default NS for SRW diagnostic elements.
850 --- 2.0.13 2004/02/23
852 Implement ZOOM_resultset_cache_reset which resets record cache.
854 Implement ZOOM_resultset_sort which sorts a result set.
856 Implement chunked HTTP transfer.
858 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
860 --- 2.0.12 2004/02/16
862 Added member 'schema' to bend_explain_rr structure so that backend
863 can specify explain record identifier. Defaults to Zeerex 2.0.
865 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
867 --- 2.0.11 2004/02/16
869 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
872 Added init command for yaz-client which sends "extra" init request.
874 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
875 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
877 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
879 Make ZOOM error code for "invalid query".
881 Fixed compilation for SSL which wasn't properly enabled for all platforms.
883 --- 2.0.10 2004/02/05
885 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
888 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
890 Added option -p <file> to make Generic Frontend Server to write PID file.
892 Added option -D to put Generic Frontend Server in background on its own.
894 Make ZOOM C recognize option "password". If unset, "pass" is used
895 (for backwards compatibility).
897 Fixed a bug in Generic Frontend Server that could make it crash if a
898 client sets characterSetNegotation bit, but didn't pass negotiation stuff
901 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
902 Must be issued before open, in order to be in effect.
904 --- 2.0.9-6 2004/01/12 Debian/Windows
906 Make the SRU server more picky WRT unknown params, etc.
908 Bug fix: ZOOM scan response didn't return displayTerm - when present.
910 New YAZ client command, options, that sets Z39.50 options.
912 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
913 options from a string of tokens (one token for each option bit).
915 Update SRW diagnostic code messages.
917 --- 2.0.9-5 2004/01/07 Debian/Windows
919 Handle user defined stylesheet for SRW/SRU.
921 --- 2.0.9-4 2004/01/06 Debian/Windows
923 Fix bug in decoding of Content-Length.
925 --- 2.0.9-3 2004/01/06 Debian/Windows
927 Fix a bug with decoding of XML packed records.
929 --- 2.0.9-2 2004/01/05 Debian only
931 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
933 Fix bug in SRW/SRU diagnostics decoding.
937 Fixed bug in Generic Frontend Server which could drop records exceeding
938 preferred message size. Reported and fixed by Irina Dijour.
940 Fixed calculation of package size for structured records in Generic
941 Frontend Server. Reported and fixed by Irina Dijour.
943 Fixed namespace for SRW/SRU diagnostics.
945 Fixed SEGV in yaz-client that occured for HTTP connection errors.
949 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
950 this version is incompatible with version 1.0 and older YAZ SRW/SRU
953 CQL changes to reflect recent changes to the specification:
954 * Documentation talks about context sets instead of index sets.
955 * Documentation talks about indexes instead of qualifiers.
956 * The CQL-to-PQF transformer's configuration file now uses
957 "index.set.name = <attributes>" instead of the old form
958 "qualifier.set.name = <attributes>". (Both forms are still
959 understood but the latter is deprecated.)
960 * CQL terms with no explicit index specified are now interpreted as
961 cql.serverChoice instead of srw.serverChoice (which of course
962 behaves exactly the same.)
966 MARC conversion can now generate ISO2709 output in another
967 character set. yaz-marcdump uses this facility if you invoke it
970 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
971 functions from there can be used from C++.
975 Frontend server now transfers memory from decoded packages to stream
978 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
979 references to show up.
981 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
982 the ZOOM Abstract API. The older names for the same options are still
983 also supported for the benefit of old applications.
985 ZOOM-C supports "implementationId" and "implementationVersion" options
986 to go along with "implementationName". These allow the user code to
987 specify identification strings to be sent to servers.
988 Add OID for the new ExtLite attribute set.
990 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
991 as requested/supplid by Ere Maijala <ere@atp.fi>
993 For generic frontend server, reverse the order of
994 "toolkit-supplied / application-supplied" strings sent as implementationId,
995 Name and Version. Also, remove the spaces around the slash. This brings
996 the GFS in line with the behaviour of ZOOM-C on the client side.
998 Add function ZOOM_scanset_display_term.
1000 yaz-client shows scan displayTerm if present.
1002 Utility yaz-iconv is now installed by default along with the man page
1005 Extend configure check for OpenSSL to use pkg-config where available (such
1008 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1009 server to specify uid/gid/mask for socket using the format
1010 unix:[user=uid,][group=gid,][umask=mask,]file=path
1011 If file= is omitted the existing format is assumed, e.g.
1013 in which case the mask is 0666 (rw for everybody).
1015 Major restructure of YAZ source. All source in libyaz is in src directory.
1016 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1017 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1019 Added man page for utility yaz-marcdump (used to be called marcdump).
1020 yaz-marcdump is installed by 'make install'.
1022 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1023 of incoming package failed.
1025 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1027 Change prototype of odr_perror: add const to message string.
1029 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1031 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1032 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1033 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1034 DNS lookup. There should not be any compatibility problems with this
1035 assuming that blocking=1 or 0 is used.
1037 Fix bad reference in UNIX comstack in function cs_addrstr.
1039 Fix for compilation on AIX.
1041 The generic front-end server (server/seshigh.c) now supports returning
1042 Init diagnostics to the client in User-information-field, in
1043 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1046 --- 2.0.4 2003/09/04
1048 Allow any CQL relation (not just all,any,exact,scr).
1050 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1051 that features the same UI.
1053 Implemented command update0 in YAZ client which is equivalent to
1054 update but uses old of Ext Update ASN.1.
1056 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1057 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1058 Previously no OID was used for this info.
1060 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1061 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1062 returns 'malformed search term' otherwise.
1064 SortResponse member resultCount now set to NULL in sort handler of
1067 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1070 Add three new utility functions for translating OIDs between various
1071 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1072 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1073 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1074 char *oid_to_dotstring(const int *oid, char *oidbuf);
1075 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1077 Reverted modifications for ES Update definition for z_IU0Update
1078 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1079 is back to YAZ 2.0.2.
1081 String value attributes for CCL parser.
1083 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1084 which their FirstSearch server returns in Init responses, sometimes
1085 carrying useful diagnostic information when Init fails. This has the
1086 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1087 "z39.50/oclcui.asn", where its definition is somewhat different from
1088 what OCLC document on their web-site, as required to interoperate with
1091 Support for anonymous authentication in yaz-client. Use the command
1094 * Fix the OID of the Index Data-local "admin" Extended Service from
1095 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1096 the 1000, which indicates a locally-defined OID, was a mistake.
1098 --- 2.0.3 2003/06/20
1100 Fix CCL directive @case handling so that it affects string match for
1101 both CCL keywords and qualifiers.
1103 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1104 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1105 Decoder has been updated with ASN.1 changes as listed in
1106 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1107 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1108 z_IUUpdate, remains unchanged.
1110 ZOOM_record_get may now return a record in a specific character set.
1111 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1112 "from" is the character set of record as returned by target. "to" is
1113 the character set to be returned. If omitted, "to" is UTF-8.
1115 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1117 New ODR utility, odr_getelement, which returns name of element for
1118 which encoding/decoding failed.
1120 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1121 in cases where a required element was omitted.
1123 Bug fix: some MARC8 sequences were not converted.
1125 New ZOOM option "step" which specifies number of records to be
1126 retrieved in one chunk. Used in conjunction with "start" and "count".
1128 SRW support for yaz-client. Use scheme http: to use it, e.g.
1131 yaz-client no longer does (un)intelligent character set conversions
1132 by default. Can be enabled with charset and marc_charset commands.
1134 xmalloc trace fix for 64-bit systems such as DEC alpha.
1136 Solaris 2.6 compile fix.
1138 New function, cql_strerror() translates SRW error codes, as returned
1139 by cql_transform_error(), into human-readable English strings. Used
1140 in yaz-client diagnostics when appropriate.
1142 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1143 converts it into a type-1 query which is sent to the server. This
1144 makes CQL available for use with all Z-servers, as opposed to the tiny
1145 minority that can handle CQL queries themselves.
1147 --- 2.0.2 2003/04/28
1149 New Debian package layout similar to the Redhat Package layout.
1151 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1152 and search result respectively.
1154 --- 2.0.1 2003/04/25
1156 Redhat package is now several packages: libyaz (runtime libraries),
1157 libyaz-devel (development and documentation, and yaz (utility programs).
1158 Package spec file by Morten Bøgeskov.
1160 New member 'schema' in struct bend_fetch_rr which the name of requested
1161 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1162 handler MAY set this to reflect the schema of the returned record.
1164 New member 'display_term' in struct scan_entry. GFS now sets member entries
1165 and allocates scan entries to be filled by user scan handler. In previous
1166 version, entries member was allocated by the scan handler. That still works,
1167 but the GFS will ignore member display_term - assuming it was NOT set by
1168 the handler. The fact that the GFS now allocates the entries both allows
1169 for new members and makes a scan handler easier to write.
1171 Fix CQL lex buffer overflow.
1173 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1174 SRU default recordPacking is string.
1176 SRU protocol support for frontend server.
1178 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1180 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1182 Added scan for the ZOOM shell (zoomsh).
1186 * String Identifers for Schemas (Amendment 5).
1187 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1188 Old definition for schema
1189 Odr_oid *schema; /* OPT */
1194 Z_InternationalString *uri;
1195 #define Z_Schema_oid 1
1196 #define Z_Schema_uri 2
1199 * resultCount parameter to Sort Response (Amendment 1).
1200 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1202 Support for SRW 1.0 over HTTP. This is an optional feature and
1203 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1206 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1207 on the same port. SRW SearchRetrieveRequests are mapped
1208 to bend_init,bend_search,bend_fetch,bend_close.
1210 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1212 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1213 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1215 ZOOM connections are SRW based if schem http is used for hostname
1216 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1217 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1219 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1220 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1221 distance=n, order=true/false, relation=le, prox unit=word. If
1222 n is omitted, distance 1 is used.
1224 Fixed problem with C compiler include path in wrong order.
1226 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1227 on Solaris. Patch from Ko van der Sloot.
1229 New MARC decode API. All new functions operate on a yaz_marc_t
1230 handle. The most important new functions are: yaz_marc_create,
1231 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1232 decode and destroy respectively. Decoder can produce formats
1233 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1234 include/yaz/marcdisp.h.
1236 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1237 to UTF-8, UCS-32, wchar_t or Latin-1.
1239 * Prototypes for yaz_iconv_-functions moved to separate header
1240 include/yaz/yaz-iconv.h.
1242 Make a few private functions 'static' in unix.c. This prevents
1243 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1245 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1246 are set when Init Response is received.
1248 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1249 but returns diagnostic set as well.
1251 New function yaz_strerror which is a portable wrapper for
1252 strerror/strerror_r/GetLastMessage.
1254 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1255 is returned for MARC. If type is "oai", then OAI MARC is returned.
1257 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1260 --- 1.9.2 2002/11/26
1262 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1264 Fix bad race conditions on SIGTERM and terminate gracefully in
1267 Move retrieval (data1) module to Zebra since nobody seems to be
1270 Add GRS-1 render for ZOOM using same format as yaz-client.
1272 --- 1.9.1 2002/10/05
1274 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1276 Fix broken ESpec handling in data1 module.
1278 SGML reader parses comments and makes them part of the data1 tree.
1280 Added several type casts so that YAZ compiles as C++ code.
1282 ZOOM didn't handle PDU encoding failures properly.
1284 Added more Bib-1 diagnostics (approved extensions).
1286 GNU configure: better check for iconv.
1288 More portable use of accept, getpeername. Check for socklen_t. Use
1289 int/size_t if socklen_t is not defined.
1293 PQF parser rejects bad queries - including those with extra
1294 characters in them. PQF parser used to silently ignore that.
1295 Cleaner API for PQF added, which allows you to get detailed
1296 error information for bad queries (see yaz/pquery.h).
1298 Fixed bug in ZOOM_record_get for type "database".
1300 Implemented mini iconv library supporting conversions between
1301 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1303 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1305 --- 1.8.9 2002/08/20
1307 Fixed ZOOM C record cache so that preferredRecordSyntax and
1308 elementSetName is used to check for already fetched records.
1310 --- 1.8.8 2002/08/02
1312 Added three members in bend_initrequest structure to facilitate
1313 character set negotiation.
1315 Fixed a bug in frontend server that could cause indefinite
1316 loops under rare conditions.
1318 Revised character set utilities (charneg.h) so that encoding
1319 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1321 For PQF, directive @term <type> sets term type for Scan/Search.
1322 Here <type> is general, string, numeric, null. The term type
1323 is inherited - just like @attr.
1325 New call odr_set_charset that sets character set conversion for
1326 international-strings on a ODR stream. Prototype is:
1327 int odr_set_charset(ODR o, const char *to, const char *from);
1328 The InternationalString is still represented as C string in YAZ
1329 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1330 won't). On the protocol level, you can use any encoding.
1332 Support for UNIX sockets in ZOOM.
1334 Solaris recv sometimes returns errno == ENOENT. It is treated as
1335 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1337 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1338 both client and server. Code by Morten Bøgeskov.
1340 --- 1.8.7 2002/05/22
1342 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1343 that they can be used directly from Visual Basic. You must recompile
1344 your windows APP if you're using ZOOM.
1346 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1347 Commands "lang" and "charset" sets language and character set respectively.
1348 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1349 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1351 Attributes from multiple CCL fields may be OR'ed rather than merged
1352 using directive "@field or". Fields are still merged by default -
1353 equivalent to "@field merge".
1355 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1358 Fixed bug in zget for parameter ExtendedServicesResponse.
1362 --- 1.8.6 2002/03/25
1364 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1366 Client displays USR.1:SearchResult-1 (hits per term).
1368 Additional Search Info for search in Generic Frontend Server.
1370 Fixed CCL parsing of "field=s".
1372 WIN32 installer - using the excellent NSIS software from nullsoft.
1374 Fixed CCL parsing of "field = - <number>".
1376 Added function yaz_marc_decode that decodes MARC for line mode
1377 display or XML (similar to that used by JZKit).
1379 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1380 Z39.50. But ISO/ILL was, however.
1382 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1383 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1385 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1386 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1388 --- 1.8.5 2002/02/03
1390 New YAZ client features: Command completion and new commands:
1391 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1392 Code provided by Jacob Poulsen.
1394 New call oid_trav, that visits all registered OIDs via callback.
1396 Function ZOOM_record_get now returns const char pointer rather than
1397 void pointer. It saves a lot of type casts.
1399 For YAZ client, command "auth" now allows you to set authentication
1400 in IdPass style. It is enabled when three tokens are given - order
1401 is user, group and password.
1403 Fix memory leaks in MARC record handling for ZOOM.
1405 New option for YAZ client, -k <kilobytes> that sets
1406 maximum record size. Similar to -k option for generic frontend
1407 server and yaz-ztest.
1409 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1411 Prefix query parser reports "fail" when bad attribute set is given.
1413 Fix in MARC decoder. Proximity logging. Fix for attribute set
1414 in scan handler for server. Patches by Shigeru Ishida.
1416 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1419 Configure option --with-openssl=<dir> now works when a directory is
1420 specified. Patch provided by Morten Bøgeskov.
1422 New option for YAZ client, -u <auth>, that sets authentication.
1424 ZOOM fix: error information was sometimes "missing", since error
1425 was cleared/reset too when it shouldn't.
1427 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1429 --- 1.8.4 2002/01/04
1431 Scan for ZOOM API. New object ZOOM_scanset. New functions
1432 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1433 ZOOM_scanset_destroy.
1435 New ZOOM function, ZOOM_connection_last_event, that returns type
1436 of last event (such as "receive data", "send data", "apdu received",
1439 New ZOOM option, schema, that specifies schema for retrieval.
1441 New CCL feature. Qualifiers can be aliases for one or more
1442 other qualifiers (if more than one is given, OR is used).
1444 ZOOM uses named result sets if target supports it.
1446 Two new YAZ client commands: . (dot, which sources a script of YAZ
1447 client commands), and ! (to execute shell command.). Implemented
1450 Working on Debian packages.
1452 --- 1.8.3 2001/11/19
1454 YAZ client enables named result sets only if target supports it.
1456 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1458 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1459 with key="host" to get same result.
1461 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1462 Function Z3950_resultset_record(s) returns references to records
1463 "owned" by resultset. To become owner use Z3950_record_clone.
1465 Function z_ext_record handles Extended Services. Thanks to
1468 --- 1.8.2 2001/11/12
1470 CCL Parser fix: ignore token comma when dealing with and-lists.
1472 Documentation updates for COMSTACK.
1474 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1475 Changed prototype Z3950_records. For some functions, int parameters
1476 were changed to size_t.
1478 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1481 New MARC decode/display function, marc_display_exl, which properly rejects
1482 non-ISO2709 records. YAZ client uses it.
1484 --- 1.8.1 2001/10/29
1486 Fix bug: local attribute set wasn't set correctly in PQF strings.
1490 * Old Z39.50 codecs no longer supported.
1492 Added ZOOM C binding. See http://zoom.z3950.org/
1494 Renamed states for COMSTACKs to avoid confusion with events.
1496 Implemented cs_look and proper cs_rcvconnect.
1498 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1500 Configure detects POSIX threads on OpenBSD.
1502 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1503 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1505 When error is returned from present handler, non-surrogate diagnostic
1506 is returned in present response (and fetch handler is no longer called).
1508 * Minor adjustments to pquery parser (PQF). Token characters may be
1509 escaped by using backslash (C-style).
1511 PQF parser allows string attribute values to be specified. For @attr,
1512 non-numeric characters after the equal-sign are treated as strings
1513 (e.g. @attr 9=title).
1515 CCL trunction character may be defined (@truncation in file)
1517 * function zget_ExtendedServicesRequest sets waitAction to
1518 waitIfPossible (was wait).
1520 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1523 CCL operator names may be set in field definition files (CCL_bibset).
1524 See ccl/bib1 for an example.
1526 Fixes in ASN.1 compiler for C++ compatibility.
1528 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1529 and "op_or" to avoid conflict with C++.
1531 Fixed problem with GNU readline detection on Redhat 7.0.
1533 Added step-size for Scan backend handler.
1535 Fixed bug that made the frontend server crash when no attribute
1536 set was specified for scan.
1538 Front-end server automatically switches to original working directory
1539 when installed as an NT service. Previously -w had to be specified to
1542 Added extended attributes for retrieval module (data1), so that data1
1543 records carry d1_readXML/SGML attributes. d1_read also supports
1544 null-data rules ( <tag/>)
1546 On UNIX when POSIX threads are available, a separate library libyazthread
1547 is created. Programmers should link with that library and the yaz library
1548 when using threads. The reason for the split was that some applications
1549 on Linux, such as Apache, doesn't work well when using shared objects that
1552 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1553 (or any frontend server) in SSL mode by specifying ssl: followed by
1554 address. Only tested on UNIX.
1556 Added feature for CCL module. Virtual structure s=al or s=ol generates
1557 and-list and or-list respectively instead of phrase search.
1561 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1562 log_mask_str. This was done to avoid name conflicts with other libraries
1563 (such as other PHP extensions).
1565 Added raw OID member for preferred record syntax (request_format_raw)
1566 and returned record syntax (output_format_raw) for backend fetch method.
1568 Config file yaz-config now accepts options so that it returns specific
1569 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1571 Shared library support for UNIX using GNU libtool.
1573 * Modified backend interface. Request/Response struct's replaced by
1574 one read/write C struct. For example bend_fetchrequest and
1575 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1576 Every handler - even search has to be registered in bend_init
1577 handler. This means that the YAZ library no longer refers to
1578 external functions and it makes it possible to make the whole
1579 thing a single DLL/SO.
1581 Added Segment handler for backend server.
1583 Added Zmbol/Zebra administrative functions to YAZ client.
1585 Threaded frontend server on UNIX (when POSIX Threads are available).
1586 Starting the server with option -T enables multi-threading.
1590 Added configure option --enable-comp/disable-comp to control use
1591 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1592 located in sub directory asn.
1594 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1595 in ${exec_prefix}/bin along with the other programs yaz-client and
1598 GNU automake used to maintain makefiles.
1600 Added several OID's.
1602 Changed retrieval module so that we can load records with no abstract
1603 syntax defined. Tagpaths in these records are fully composed of string
1606 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1610 On UNIX, the generated makefile now supports a proper 'make install'.
1611 The prefix can be set via GNU configure to set the install location
1612 (default is /usr/local).
1614 * YAZ programs client and ztest were renamed to yaz-client and
1615 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1616 locations, such as /usr/bin,/usr/local/bin,etc.
1618 * YAZ Header files were moved from include to include/yaz. YAZ Header
1619 files are referred to as include <yaz/log.h> rather than <log.h>.
1620 The YAZ include path (-I ..) is therefore the same as before. Programmers
1621 should update their #include statements or use -Ipath/include/yaz
1622 instead. The main motivation for doing this change is that YAZ header files
1623 can be installed in "standard" locations /usr/include,/usr/local/include
1624 without introducing conflicts, since ALL YAZ header files are stored
1625 in subdirectory yaz (under /usr/include for example).
1627 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1628 rather than project/workspace files. We switched because project files
1629 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1632 Changed name of logging function, logf, to yaz_log, to prevent name
1633 clash with some math-log functions. The YAZ header log.h defines logf
1634 to yaz_log (#define) so there should be no incompatibilities by this
1637 Added bend_start/bend_stop handlers for server. These handler are
1638 called on start/stop of server. For windows they are called whenever
1639 a service is started/stopped.
1641 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1642 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1643 in util/yc.tcl. The auto-generated C code structures are, in a few
1644 cases, incompatible with the old decoders. There are differences in the
1645 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1646 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1647 The preprocessor variable ASN_COMPILED is defined when the compiled
1648 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1649 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1650 wish to use the old encoders/decoders you can specify --disable-yc
1653 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1654 version so that it supports both new - and old version of DB Update
1656 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1657 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1658 change. The name parameter can be set to 0 in which no name is specified
1659 for the construction. The macros odr_implicit and odr_explicit sets name
1660 parameter to zero for the construction involved. New macros
1661 odr_implicit_tag and odr_explicit_tag are similar to the others,
1662 except that a name parameter is added. For programmers' that don't use
1663 ODR they probably only need to change the call to z_APDU and z_External.
1665 Added access control facility by interfacing the TCP wrapper library.
1666 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1667 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1668 name of the daemon and enables the access control as specified in
1669 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1671 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1672 den Dool <H.M.vdnDool@kub.nl>.
1674 Added reference ID parameter to most functions in server API - refer
1675 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1677 Changed name of ccl library to libccl.a (was ccl.a).
1679 Fixed bug in decoder for Explain (Category TargetInfo).
1681 Added support for GNU readline in client. Thanks to Jacob Poulsen
1682 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1684 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1685 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1686 IMPLEMENTATION! This change was made to the development version before
1687 the ZIG decided to retract the amendment. If any users MUST be
1688 compatible with the original Update definition, PLEASE CONTACT US, and
1689 we will include a separate definition corresponding to the old Update
1690 ES. Note that because of the change to the ASN.1 of the
1691 TaskPackageRecordStructure we cannot define a single structure that
1692 will support both versions.
1694 * Added const modifier to buffer parameter for some ODR/BER encoding
1695 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1696 completeWAIS, odr_dumpBER.
1698 Fixed bug in client.c which caused a crash when a scanResponse didn't
1699 contain positionOfTerm.
1701 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1702 * will cause an error in a client if a non-YAZ target sends both a
1703 * list of Scan entries and non-surrogate diagnostics.
1705 Retrieval module enhancements. Tag sets may be typed in the reference
1706 to it. From the .abs-file the "tagset" directive takes a third optional
1707 integer type for the tag set referenced. From a .tag-file the "include"
1708 directive takes a third optional type as well. The old "type" directive
1709 in the tag set itself is still recognized but acts as the default type
1712 Backend interface change. Individual Scan terms returned from bend_scan
1713 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1714 in include/backend.h.
1716 Retrieval module enhancements. Multiple tag sets and attribute sets may
1717 be specified in abstract syntax specs. Revised the error/warning for
1718 logging messages reported by the retrieval module when reading the
1721 Object Identifier system (oid_..) changed. The API is backwards
1722 compatible but the oid-routines now allocates new OID's when needed.
1723 Raw OID's may be specified in oid_getvalbyname.
1725 YAZ now uses GNU configure to generate Makefile(s).
1727 * Minor changes in some of the member names of DeleteResultSetRequest and
1728 DeleteResultSetResponse. See include/proto.h.
1730 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1731 and added member 'languages' in TargetInfo (which was missing).
1733 Changed the way attribute sets are handled in the retrieval
1734 module. These are now cached, just like the abstract syntaxes
1737 Changed YAZ so that it links with compiled ASN.1.
1739 Added Explain-schema definitions and mapping routines. The following
1740 Explain categories have been implemented: AttributeDetails,
1741 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1743 Fixed minor bug in Windows version of Server Library.
1745 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1747 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1749 Added EXTERNAL: UNIverse Resource Report (non-standard).
1751 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1752 ENUMERATED and SET OF.
1754 * Added 'const' to some of the char pointer arguments for the
1755 functions, data1_read_node, data1_getelementbytagname,
1756 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1759 Fixed bug in data1_insert_taggeddata - the last_child member of
1760 parent wasn't initialised.
1762 * Changed data1_read_record and data1_read_node so that the supplied
1763 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1764 doesn't refer to any parts of the "SGML"-buffer.
1766 Fixed bug in server library (Windows version of statserv_remove).
1768 * Changed code so that it compiles as C++. The type definition
1769 of Odr_fun which is a member of Odr_arm was changed. The result is,
1770 that an explicit typecast is needed for the fun pointer when
1771 using Odr_arm - as in:
1772 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1774 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1776 Implemented the new structured date and time definition as approved
1777 by the ZIG. Added schemaId element to the specificTag in Espec-1
1778 (also approved at the last ZIG). Thanks to RVDM.
1780 Added some Object identifiers (RVDM).
1782 Changed the Update Extended Service (RVDM).
1784 Added command "refid" to client which specifies referenceId for
1785 the following requests.
1787 Implemented extended service handling for server. See ztest.c
1788 for an example as well as backend.h. New handlers are registerd
1789 in the Init handler.
1791 * Changed interface for sort in server.
1793 Added new members to statserv_options_block. It allows a server
1794 to read options from another source than just the command line. Thanks
1795 to Charles Woodfield.
1797 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1798 renamed to zboolean. Some C++ compilers complained about the name.
1800 Minor changes to gils.abs. Added index 's' (sort) on title
1801 and date/time-last-modified.
1803 --- 1.4pl2 1998/1/30
1805 Fixed bug in server library regarding inetd mode (-i). This bug
1806 was introduced by release 1.4.
1808 --- 1.4pl1 1998/1/29
1810 Added sort facility in client and backend server interface.
1812 Fixed problem with dependencies in Makefile(s).
1814 Fixed bugs for encoders/decoders of extended services and
1817 Implemented sub-tree feature for schemas. Sub-trees are
1818 referenced in *.abs-files. See explain.abs for an example
1819 of the use of this feature.
1821 Modified bib1.att; local attributes for ANY didn't include
1822 ANY itself (only affects use of the retrieval module).
1824 Fixed bug in plain SGML reader in function data1_read_node:
1825 tags with prefix "var" was incorrectly interpreted as variants.
1827 Added feature "sub-schemas" to enable references to - and definitions
1828 of - group of elements.
1830 * Removed member parent from type data1_element (in data1.h).
1832 Implemented function odr_nullval() that returns the value of
1835 * Removed member num_children from data1_node (in data1.h).
1837 Made NT service interface part of the server library. The
1838 function statserv_main uses the NT service when required and
1839 calls the statserv_start / statserv_close routines.
1841 Routine zget_SearchRequest and zget_PresentRequest fills
1842 resultSetName/Id member with "default" instead of "Default".
1844 Fixed memory leak in server. Request queue member wasn't freed.
1846 Fixed nmem_exit so that memory is freed.
1850 Revised the CCL parser utility to be thread safe.
1852 Added function, oid_ent_to_oid, to replace the function
1853 oid_getoidbyent, which is not thread safe.
1855 * Added nmem_init and nmem_exit to initialize and release
1856 NMEM resources. Function nmem_init should be called once in the
1857 initial thread before NMEM/ODR is used. statserv.c and client.c
1858 have been changed accordingly. The change was necessary to make
1859 NMEM thread safe. The NMEM memory pool is shared amongst threads
1860 in a process. Unix-based applications will still work fine without
1863 Added NT Services interface for the the Z39.50 (statserv) Server.
1864 Refer to the ztest.c source on the usage.
1866 Windows 95/NT port using MSVC5.0. Project files are included in the
1869 * Defined new 'global' handle for the retrieval (data1) system. The
1870 new handled, data1_handle, describes the state of the data1 system.
1871 This handle is passed as first argument to virtually all
1872 data1 related routines. The functions data1_create and data1_destroy
1873 creates and destroys a data1 handle respectively.
1875 Added ODR encode stream member to all backend request structures
1876 init, search, scan etc. This stream should be used to allocate all
1877 memory used for the response when thread safe operation is needed.
1879 Changed the comstack utility, cs_addstr, to be thread safe. The
1880 returned hostname string returned by the function is now part the
1883 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1884 function. The cs_straddr takes a COMSTACK handle as argument, so this
1885 function must be used after cs_create and before bind/connect.
1886 This function is thread safe.
1888 Moved test server to 'ztest' directory - generic server code still
1889 in 'server' directory.
1891 Made prefix query (pquery.c) utility thread safe.
1893 Added new function modifier YAZ_EXPORT to 'export' public DLL
1894 functions when using windows (see include/yconfig.h).
1896 Added definitions to the OID database (util/oid.c) (RVDM).
1898 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1900 Added call to ccl_rpn_delete in client program.
1902 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1903 release of RPN structure.
1905 Added support for C++, headers uses extern "C" for public definitions.
1906 With input from RVDM.
1908 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1909 Thanks to Ronald van der Meer (RVDM).
1911 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1913 Added support for private extensions to the OID database
1914 (oid_setprivateoids()). Thanks to RVDM.
1916 Added optional, physical ANY (key replication)
1918 Fixed null-reference problem in GRS-1 output filter.
1920 Proximity operator added to Prefix Query Format (PQF).
1922 In test client command "base" accepts multiple databases.
1924 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1928 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1930 Smallish bug-fixes in the new encoders/decoders (explain).
1932 Bug fixed in DeleteRequest.
1934 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1936 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1938 Added SOIF syntax (using private OID for now) to retrieval module and client.
1940 Added Update extended service.
1942 Added SearchResult-1 additional info structure.
1944 Added optional CCL (ISO8777) interpreter as separate module. Available
1947 --- 1.2 1996/6/10 (1st anniversary release)
1949 Added Summary record syntax. Lightly tested.
1951 Added OPAC record syntax. Untested.
1953 Added ResourceReport service encoders/decoders. Untested.
1955 Fixed bug in z_Unit - wrong tagging on unitSystem.
1957 Fixed bug in the DiagRecs decoder.
1959 Added options for max PDU size and session timeout to frontend-server.
1961 Added documentation of query-language parsers and other supporting utilities.
1963 [frontend-server] Added Attribute set to the bend_scanrequest API.
1965 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1966 surrogate diagnostics were generated.
1968 [retrieval] Allow multiple local values for attribute.
1970 [retrieval] Allow multiple attributes per element in .abs files. index type.
1972 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1974 --- 1.1pl2 1996/4/10
1976 Minor changes, mostly specific to Zebra's requirements (retrieval)
1980 Repaired bug in frontend server when running multiple listening
1981 endpoints in dynamic mode.
1983 z_External() now won't break if a known, ASN.1 value comes encapsulated
1984 in an octet-string. The value will pass through unmodified in an Odr_oct.
1986 Added a bit of code to the demo client to decode & display
1987 ASN.1-structured records represented in the octet-aligned branch of
1988 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1990 Added z_ext_getentbyref() to the ASN module. Doc updated.
1992 * Completed the SCAN definition in the ASN module. This may break SCAN
1993 code based on older YAZ-versions at compile-time. The fix is easy -
1996 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1997 under the SCAN definition. Remember to initialize this, server-people.
1999 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2000 that this does not extend to ODR and ASN.
2002 Comstack allows insertion of established socket (primarily for
2003 inetd-operation of servers). Doc updated.
2005 Front-end server can now start from the inetd in TCP mode. Doc
2008 --- 1.0pl4 1996/1/24
2012 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2013 the rank and record number.
2015 Adjustments to the frontend server.
2017 Fixed diagnostic BER dumper. It ignored the file argument.
2021 Various changes to retrieval module.
2023 Changed the union discriminators of the protocol files from enums to
2024 ints paired with #defines.
2026 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2029 *Changed operator in the RPN structure to 'roperator', again to avoid a
2032 Fixed problems in Explain decoders/encoders.
2034 --- 1.0pl2 1995/12/6
2036 Memory bug in log module fixed.
2038 --- 1.0pl1 1995/12/5
2040 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2042 Bug in Explain DatabaseInfo module fixed.
2044 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2048 The shift to v1.0 signals that we now consider the *core* functionality
2049 of YAZ reasonably stable (the core being more or less equivalent to
2050 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2051 tested (Explain not at all - though that will happen soonish).
2053 Minor changes to code to support Windows port.
2055 Various minor changes after we're getting to use GRS-1 & co. more.
2057 Added Espec-1 format.
2059 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2060 of the protocol and it cannot be selected when encoding (maps into 'string'
2061 when decoding). Needed to talk to some servers.
2063 Demo client can request simple element set names.
2065 Added Diagnostic Format encoders/decoders.
2067 Added simple Close handling to frontend server (no hooks for resource
2068 reporting yet), and demonstration client.
2070 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2072 --- 1.0b3 1995/08/24
2074 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2075 handled incorrectly when records were requested in the searchResponse. This
2076 will only affect you if you use the frontend-server.
2078 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2079 Test-client will ask for and print GRS1. Ztest will return dummy records
2082 Added Explain encoders/decoders to the service-level API. Untested.
2084 Added Extended Services: Item Order encoders and decoders to the Service-
2085 level API. Untested. We could use a recent copy of the pertinent bits
2086 of the ILL protocol to add those bits.
2088 Added diagnostic format 1 encoders/decoders to the service-level API.
2091 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2092 odr_cons.c, which causes a more correct output.
2094 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2095 was always set to 0 when no records were requested in the searchRequest.
2097 * Added better external-handling. This shouldn't harm old code that
2098 *encodes* externals. It can break code that looks for a
2099 'single-ASN1-type' representation, since those types that are known
2100 are now decoded immediately. Look at the SUTRS sample code in
2101 seshigh.c and client.c. Documentation updated.
2103 Handling of structured records in bend_fetchresponse. Length -1 marks
2104 structured record, type is deduced from format field.
2106 --- 1.0b2 1995/06/27
2107 Fairly quick maintenance release to add SUTRS support.
2109 Fixed handling of SUTRS records in the demonstration client.
2111 * Added format field to the bend_fetchrequest and bend_fetchresponce
2112 structures of the backend API (frontend server). When the record is
2113 returned, the value of the format field is mapped to an OID. The
2114 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2115 of the record. The special value VAL_NONE in the bend_request means
2116 that no specific format was requested by the client. Documentation
2117 updated accordingly. Test server (ztest) will return a fixed dummy
2118 SUTRS record if your client requests SUTRS.
2120 Documentation updated accordingly.
2122 You can now set external libraries and RANLIB support in the top-level
2126 First public release.
