1 New ZOOM C option, "rpnCharset", which allows client-side conversion of
4 Clean-up the CCL API. Moved some internal structures from ccl.h to
5 private header cclp.h. Changed ccl_parser_create so that a Bibset must
6 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
7 This is replaced by ccl_parser_find_str which takes a string instead.
9 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
10 libyaz.la is the core of YAZ except the generic frontend server and
11 does not depend on POSIX threads anymore. libyaz_server.la is the
12 generic frontend server facilities and uses POSIX thread functionality
13 if available. The libyaz.la no longer depends on POSIX threads because
14 the number of global structures is limited. NMEM no longer re-uses blocks
15 between threads ; it simply free's memory immediately but allocates in
16 "large" chunks as usual. We don't expect any performance penalties
17 because of this. The yaz_log system is still using a global log_level so
18 caution must be taken when modifying it with yaz_log_init_.. +
19 yaz_log_mask_str. This, however, should not cause any trouble because
20 these functions are called during initialization of application code
21 anyway. `yaz-config --libs server` returns libs for server applications;
22 `yaz-config --libs` returns libs for non-server applications.
24 New OID database - with public definitions in oid_db.h. Removed old OID
25 database including the head oid.h and definitions such as enum oid_value
26 and struct oident. The new OID database uses the same string names as
27 before but the 'protocol' is gone. There are now only two representations
28 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
29 converts from string to OID; functions with prefix yaz_oid_to_string
30 converts the other way.
32 Change to emit_term() in CQL-to-PQF query translation: when a term has
33 the /regexp relation modifier, do not process it for leading and
34 trailing "^" and "*", which have quite different meanings in regular
37 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
38 write handlers no longer carries a 'last' parameter. This will make
39 yaz_iconv flush "less" characters. A flush is performed by call to
40 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
42 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
43 removed, because function yaz_query_to_wrbuf does the same.
45 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
46 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
48 Deprecated MARC utility functions removed.
50 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
53 Branch split: YAZ_2_1_55_branch
57 Fix to ZOOM-C so that transparent reconnection is properly handled on
58 connections that are in asynchronous mode.
60 Fixed compilation on OpenBSD 4.0.
62 Large strings in GRS-1 records are now properly displayed in yaz-client.
64 Added character conversion support for "advancegreek"; based on patch from
67 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
68 sequence is met. Before the error was not set so it would be unknown.
70 Adjust yaz-marcdump MARC reader so that it skips until record separator
75 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
76 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
77 fd_set structure used as a bitmask for the FDs to be selected on.
79 Using ACX_PTHREAD macro to check for POSIX threads.
81 Fixed have-vsnprintf check.
85 Fixes for configure on BSD. Bug #900.
87 Added snprintf/vsnprintf wrappers for systems that don't have
88 limits (heavens forbid).
90 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
91 created before all previous tasks were completed and removed from the
92 task queue, the new task could be removed by a mistake.
94 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
96 Implemented pass-through CQL-to-PQF conversions. Bug #861.
98 Fixed bug #832: Problem with MARC/charset in yaz-client.
100 Fixed bug #668: save command line history for yaz-client.
102 Fixed bug #830: pkg-config support.
104 --- 2.1.48 2007/01/23
106 Extended ZOOM result set options with two options that may be read by
107 a client: resultSetStatus and presentStatus with values as specified for
109 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
111 Fixed bug #827: Using SSL fails on Debian etch.
113 Fixed bug #826: Weird looking chars for set of MARC records.
115 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
116 that is treated as an ItemOrder with itemRequest being an XML document
117 external. The value of "doc" is the content.
119 Extended the GFS search facility. New member of bend_search_rr
120 'estimated_hit_count' signals that hits is known to be an estmate
121 (higher or lower than real hit count). New member 'partial_resultset'
122 signals that the search was partial (hit count is lower or equal than
123 real hit count). For Z39.50, the information is stored in resultSetStatus
124 member of SearchResponse APDU. For SRU, the information is signalled
125 via SRU diagnostic 59: "Result set created with valid partial results
128 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
130 --- 2.1.46 2007/01/13
132 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
134 Added ZOOM_connection_peek_event.
136 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
137 the following new functions:
138 ZOOM_event_nonblock, ZOOM_connection_process,
139 ZOOM_connection_get_{socket,mask,timeout},
140 ZOOM_connection_fire_event_{timeout,socket}.
141 The existing blocking event handler, ZOOM_event, is a wrapper for the
142 + blocking ZOOM_event_sys_{poll,select}.
144 Implemented function ccl_xml_config which parses XML version of CCL
145 configuration (bug #798).
147 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
149 Added timings utility (yaz/timing.h)
151 --- 2.1.44 2007/01/03
153 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
156 Fixed bug #779: Rotation of apdu.log fails.
158 Fixed for character set conversions:
159 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
160 Honor G1 set in MARC-8 decoding.
162 --- 2.1.42 2006/12/17
164 Fixed bug #775: char conversion does not handle Alternative UTF-8
167 Implemented function yaz_marc_read_line which parses MARC line format
168 records. There is a wealth of formats out there. So far, this function
169 reads line records produced by yaz_marc_write_line.
171 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
172 more generic and easier to remember(!) options: -i format and -o format
173 which specifies input format and output format respectively - where
174 format is one of "marc", "marcxml", "line", "marcxchange".
176 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
177 does not print anything except warnings for records.
179 For yaz-marcdump, added support for MARC split into files (-s) with a given
182 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
183 spec, at http://www.loc.gov/standards/sru/record-update/
184 This has changed the binary layout of the following structs:
185 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
186 bend_update_rr . Patch by Ko van der Sloot.
188 Added GFS utility function bend_assoc_is_alive which returns 1 if
189 association is still alive (client is connected); 0 otherwise (client
190 closed connection). This allows busy servers to stop working for
193 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
194 been a separate piece of software. This version of ziffy has been modified
195 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
197 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
199 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
200 Client code may now interrogate options such as "init_opt_sort" to
201 find out whether the server claims to support various options.
203 --- 2.1.40 2006/11/27
205 Added utilities yaz_{set,get}_esn to set/get element set name from
208 Removed the build of libyazthread.la. The libyaz.so is the threaded version
209 of YAZ and has been so since YAZ 2.1.10.
211 Implemented ZOOM_record_error which returns error information for
212 record (surrogate diagnostic).
214 --- 2.1.38 2006/10/31
216 Updates for SRU Update by Ko van der Sloot:
217 1. Changed name from "operation" to "action"
218 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
219 versions in the code, marked as 'backward compatible'.
220 3. Added diagnostics for SRU Update.
222 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
224 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
226 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
228 For GFS, fixed problem with SRU diagnostic 'First record position out of
229 range' being issued for 0 hits.
231 zoomtst10 part of Windows Build.
233 --- 2.1.36 2006/10/13
235 Implemented yaz_filepath_comp which splits a path into file path
236 components (required by Zebra 2.0.3+).
238 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
239 BSD inspired license until now so this should not have any real impact on
240 anybody. See http://www.opensource.org/licenses/bsd-license.php
242 Fixed bug #687: Missing log lines.
244 Fixed bug #678: CQL to PQF translation does not preserve double-quote
247 Fixed bug #689: SRU diagnostics to be added.
249 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
250 whether a connection is idle (no more work do do).
252 --- 2.1.34 2006/10/04
254 Change type of optval from long to int for invocation of setsockopt with
255 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
257 Added support for specifying the max log file size for the Generic
258 Frontend Server. The size is given with option -r.
260 --- 2.1.32 2006/09/21
262 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
264 --- 2.1.30 2006/09/17
266 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
269 Fixed bug in Generic Frontend Server that could cause a server to stop
270 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
272 For the generic frontend server, the maximum record size is used as maximum
273 size of incoming packages (SRU + Z39.50). The value until was previously
274 only used in Z39.50 Init negotiation and, later, in a session controlled
275 sizes of records returned. This is controlled using -k option. It can be
276 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
278 --- 2.1.28 2006/09/04
280 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
283 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
285 New option for yaz-marcdump -lpos=value which allows setting a portion
286 of MARC header to a certain value.
288 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
290 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
291 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
293 --- 2.1.26 2006/08/15
295 Fixed problem with SRU mode type (soap, get, post) for yaz-client
298 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
300 --- 2.1.24 2006/08/08
302 Fixed MARC ISO2709 encoding routines to deal with character set
305 Minor changes to GFS logging. Database included in search request log
308 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
309 cached/multiple records.
311 Shared libraries are built by default on Unix+configure.
313 Changed cql2pqf transformation to use a different evaluation order. The
314 new order is: always, relation, structure, position, truncation, index
315 and relationModifier. Old order was: always, relation, relationModifier,
316 structure, index, position, truncation. Note that the the latter ones
317 override former ones for identical attributes.. The new scheme means that
318 it is possible to override any existing attribute with a relationModifier.
319 And also that it is possible to override everything for the index rule
320 (except the ones listed in relationModifier). No order is perfect but this
321 one, we believe, covers more real cases.. The "always" should have been
322 called "default", since the attributes there can be overridden with all
325 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
326 compilation phase, but also for yaz-config --cflags output. This allows
327 us to have public headers with Libxml2 stuff in them . It should also,
328 eventually, make Libxml2 checks redundant in packages using YAZ, such
331 --- 2.1.22 2006/06/15
333 Changed SRU update structure bend_update_rr so that SRU diagnostics are
334 stored in uri, message and details.. Previously diagnostics were stored
335 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
336 compatibility.. but he's probably the only one affected, so.
338 Added support for CCL, compiled on the client side, in ZOOM-C. This
339 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
340 input; the resulting query objects can be used for for searching with
341 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
343 YAZ' configure searches for OpenSSL by default.
345 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
346 SL_CTX_use_certificate_file. See
347 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
348 for more info. Thanks to Ko van der Sloot.
350 --- 2.1.20 2006/06/02
352 Bug #600: SRU GET, POST support for yaz-client. Introduced
353 command 'sru' which selects method SOAP/GET/POST.
355 Allow missingValueAction to be specified for the sortspec string -
356 function yaz_sort_spec. By default, the missing value action is null.
357 Use ! to specify "abort". Use = followed by stringvalue to specify default
360 Ensured that Present-handler (if defined) is called in GFS before any call to
361 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
362 searchRetrieve requests.
364 Documentation for YAZ is now based on the Docbook XML/XSLT using
365 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
366 is no longer depending on jade/openjade or docbook-to-man scripts.
367 PDF is no longer part of the distribution - but can optionally be
368 made using DSSSL/jadetex or FOP.
370 Added retrieval handling support in Generic Frontend Server to support
371 conversion between MARC/XML as well as XSLTtransforms. See
372 etc/yazgfs.xml for an example.
374 Added Authentication support to Generic Frontend Server in SRU
375 mode. Authentication using HTTP Basic is supported, as is the use
376 of 'x-username' and 'x-password' parameters in the request itself.
378 Added support for a new character set MARC8s identical to MARC8 except
379 that it converts combined characters to single Unicode characters in the
380 Latin-1 range (when possible).
382 --- 2.1.18 2006/04/24
384 ASN.1 compiler 0.4: generates brief Doxygen file header for
385 generated .h/.c files.
387 Utility yaz_iconv now supports conversion to MARC-8.
389 New facilities for the MARC module. The reading - and writing of
390 content are separate methods for the yaz_marc_t handle. The following
391 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
392 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
393 format). Write functions have prefix yaz_marc_write_.. The existing
394 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
395 available. Removed support for OAI-MARC and simplexml (not the
396 simplexml from PHP5).
398 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
399 to be returned for this connection.
401 --- 2.1.16 2006/03/31
403 Allow multiple languages and charsets to be specified with
404 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
405 negcharset iso-8859-1,utf-8
407 Translation of proximity nodes from CQL into PQF now works.
409 Moved to automake 1.8, 1.9.
411 Added function yaz_log_set_handler which allows a log handler to be
412 installed. This handler will be called for all log messages. Output
413 to file is also produced; but that can be disabled by passing NULL
414 fname to yaz_log_init_file.
416 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
418 For SRW (including GFS), accept application/soap+xml as content-type
421 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
422 produces NO stylesheet reference even if a default stylesheet is specified
425 --- 2.1.14 2006/03/14
427 Updated Windows package to include yazd.dll + yazd.lib for the
428 Development component.
430 If the environment variable YAZ_LOG is set, then it is used as a
431 string indicating the default level of logging to use if not
432 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
433 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
434 used as before. So, for example, to omit warnings from YAZ logging,
437 cql_transform() now map structure and other attributes before indexes,
438 so that index-specific structures and other attributes can override
439 defaults. So now a combination of mapping specifications such as:
441 index.dc.date = 1=date-modified 4=5
442 does the right thing.
444 cql_transform() now also respects the "always" mapping specification,
445 which establishes an initial set of attributes to be used for all
446 terms except where overridden by more specific attributes associated
447 with the index, relation or modifier.
449 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
450 which mode to use; one of "post", "get" or "soap" (SRW, default).
452 Fixes for yaz_iconv routines: changed trie-based character set conversions
453 to use only non-negative values for bit fields due to Sun's C compiler not
454 supporting negative values.
456 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
457 sequences where not read correctly. Fix by Rustam Usmanov.
459 Updated win/makefile to use options, settings which makes things
460 compile with VS C 2005.
462 --- 2.1.12 2006/02/01
464 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
466 In ZOOM socket code, use select instead of poll on MacOSX.
468 ZOOM-C now support client-side compilation of CQL into RPN that is
469 sent to the server, enabling CQL to be used against all Z39.50
470 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
471 ZOOM_query object, and submit it using ZOOM_connection_search().
472 The CQL-to-RPN translation uses a configuration file, the name of
473 which must be specified in the Connection's "cqlfile" option.
475 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
476 function, which takes as its start-term parameter a ZOOM_query object
477 (which may have had either CQL or RPN set into it).
480 --- 2.1.10 2005/11/29
482 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
483 GFS to support this as well. Backend handler, bend_srw_update, does the
484 update work. Code contributed by Ko van der Sloot.
486 Allow retrieval of Search Result-1 information in ZOOM by the use of
487 options that are attached to a result set. ZOOM documentation updated
490 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
491 UTF-8 conversion. Patch by Raj Patel.
493 Added option -m to GFS to control formatting of timestamps in log file.
495 Added 'exit' as synonym for 'quit' in yaz-client
497 Added support for specifying SRW resultSetId + resultSetIdleTime in a
498 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
499 for the new members. Patch by Ko van der Sloot.
501 Added support for SRU POST. It is supported for content-type
502 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
504 Do not build the separate Multi-threaded (MT) library libyazthread.la.
505 Instead make the library libyaz.la multi-threaded. Threading as a whole
506 can still be disabled by configure option --disable-threads. Previosly,
507 with older GLIBCs there were problems with MT libs under Apache. This
508 has now been fixed a long time ago.
510 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
513 CQL module modified to be case insensitive for relations/indexes/operations.
515 Fixed bug in CQL transform code: incorrect value relationModifieder
518 Added 'show all' command for yaz-client which retrieves all results
521 Added new yaz-client, xmles, which takes a (private) OID and
522 a document to be sent as an extended service request.
524 Describe new yaz-client commands wait_response and set_auto_wait.
526 Increase TCP/IP listener backlog from 3 (which I am guessing was
527 copied from the SunOS manual entry way back when) so SOMAXCONN, so
528 that the socket will queue as many incoming connections as it's able
529 to handle ongoing connections. In other words, it will never now
530 refuse a connection that it would be able to handle merely because
531 it's not got around to accepting() enough of the pending connections
532 yet. This is the behaviour anyway under Linux, where the listen()
533 argument is ignored; but not under BSD and on systems such as
534 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
535 YAZ-based servers should now be uniform across operating systems in
538 yaz-marcdump uses 64-bit file access on some systems. This is enabled
539 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
540 This allows yaz-marcdump to read large MARC batches (>2 GB).
542 Modified all YAZ source files - except the source which is auto-generated
543 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
546 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
547 corresponding to the existing *_setl() function. These allow option
548 values containing arbitrary valuues.
550 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
551 ZOOM_resultset_sort() in new applications. Its behaviour is identical
552 except that it returns an indicator of whether or not the sort
553 criterion was accepted (0 for OK, -1 for invalid).
557 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
558 MARC output rather than returning "new" buffer.
560 yaz-client warns about unknown init options.
562 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
566 Added support for SRW sort in Generic Frontend Server. Patch
567 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
568 sortKeys - or NULL if none is provided.
570 Fixed bug #307: It was impossible to specify indefinite/no timeout
571 for ZOOM_event. Special timeout value -1 now means indefinite timeout
574 Added support for multiple languages and charsets to be specified in
575 ZOOM. Each charset/language is separated by a blank. If negotiation is
576 in effect in init-response, Option
577 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
578 Code based on patch by Vasiliy Osadchuk.
580 Fixed bug #306: infinite recursion that occurred when calling
581 yaz_log_level_init as the first call (before other log level or
584 Fixed bug in scan handling in front end server: if preferred-Position-In-
585 Response was non-present, a NULL pointer referece was performed.
589 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
590 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
591 now defined for all those error codes. So instead of putting 109 in
592 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
593 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
595 Modified the yaz-marcdump utility to skip garbage bytes between MARC
598 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
600 Program yaz-client now exits and produces an error message if multiple
601 Z39.50 servers are specified on the command line (none or one allowed
604 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
609 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
611 Fixed bug #272: Preserve spacing for CCL terms.
615 Added support for virtual hosts and multiple backend servers for
616 the YAZ frontend server. The configution is XML based and
617 support specificition of CQL to RPN mappings and explain information.
618 See section "Virtual Hosts" in the YAZ manual.
620 Extended OPAC display utility. OPAC display utility renders
621 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
622 to supplement yaz_marc_decode_wrbuf.
624 Fixed a bug in MARC decoder that could caused it to crash for some
625 invalid MARC records. More diagnostics and warnings where added in
626 XML output (warnings, etc are stored in comments).
628 --- 2.0.34 2005/02/08
630 Fixes for UNIX domain sockets. Bug #261.
632 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
634 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
635 Added yaz_marc_subfield_str which defines subfield lead string which is
636 used in YAZ_MARC_LINE format. Default string is blank+$. Added
637 yaz_marc_endline_str which defines end of fields string used in
638 YAZ_MARC_LINE format. Default string is newline.
640 Experimental support for MarcXChange. This format can be produced
641 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
642 http://www.bs.dk/standards/MarcXchange.xsd
644 Added yaz-client commands scansize that sets maximum number of
645 entries to be returned by scan.
647 --- 2.0.32 2005/01/11
649 Added support for SRW scan in yaz-client and Generic Frontend Server.
651 * Added whereInList member to SRW Scan Term.
653 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
655 Fixed NMEM system to return aligned blocks on the smallest boundaries
656 that are suitably aligned for all possible types on the particular
657 architecture YAZ is being built for.
659 --- 2.0.30 2005/01/04
661 Fixed numerious warnings that was issued with newer versions of GCC.
663 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
664 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
667 Make YAZ Generic Frontend Server slightly faster.
669 Enhance (and reduce) logging for Generic Frontend Server.
671 Revert YAZ log system so that it flushes every write operation
672 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
674 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
675 instead of LOG_, due to name clash with syslog(3). LOG_ are still
676 present. New applications should define YAZ_USE_NEW_LOG=1 - this
677 will effectively disable old definitions.
679 --- 2.0.28 2004/11/09
681 Added yaz_log_time_format which specifies log format using
684 Added yaz_log_module_level which returns mask for a module. Value
685 is non-zero mask a if module is enabled; zero if disabled.
687 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
688 in include/yaz/cql.h.
690 Fixed bug #176: Dont throw diagnostics on empty SRU args.
692 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
694 Fixed bug #172: RPM builds does not enable SSL.
696 Doxyfile.in part of dist. Doxyfile generated by configure.
698 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
699 are given and the corresponding component does not exist.
701 Extend CCL documentation in YAZ reference. Describe r=r.
703 --- 2.0.26 2004/10/01
705 Fixed MARC->MARCXML conversion to properly deal with
706 fields, subfields, indicators having non-ASCII characters.
708 Fixed MARC->MARCXML conversion so that ASCII control characters
709 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
712 Added YAZ GFS support for conversion from Z39.50 surrogate
713 diagnostics to SRW surrogate diagnostics.
715 Bug fix: YAZ GFS did not return schema in explainResponse.
717 --- 2.0.25 2004/09/30
719 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
720 now converts recordSchema to elementSetName as well as schema URI.
722 Fixed bug in COMSTACK that prevented HTTP request packages from being
725 --- 2.0.24 2004/09/29
727 Added CCL facility r=r "range" which is similar to r=o "ordered" but
728 does not require white-space before and after the dash in a range, e.g.
729 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
732 Fixed a few AC_TRY_LINK configure tests that did not operate properly
733 due to new GCC removing "redundant" code.
735 Added yaz-client commands scanpos and scanstep that sets preferred
736 position and step-size for scan.
738 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
740 Added CCL utility ccl_qual_buf which parses one or more CCL
741 spec lines in a buffer.
743 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
744 of name and value - ignoring empty lines and comments.
746 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
748 Added odr_get_element_path which returns current element path for an
749 ODR handle. This utility is useful in error handling or user-defined
752 Added ODR_PRINT utility odr_set_stream which is is a more generic
753 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
754 to a write function and pointer to close function. The close function - if
755 non-NULL - will be called during odr_destroy.
757 Fixed bug in CCL parser where truncation char was not removed from
758 right side when truncation=both was in effect.
760 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
763 --- 2.0.23 2004/08/11
765 Fix buffer overrun in CQL parser when dealing with proximity (%).
767 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
768 to UTF-8/UCS conversion is now only based on codetables.xml.
770 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
772 --- 2.0.22 2004/08/06
774 Add support for more "commit changes" in ZOOM (uses Extended Services).
776 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
779 Yet another small fix for configure of SSL.
781 --- 2.0.21 2004/05/14
783 Fix SSL libs for configure when --with-openssl=DIR is given.
785 --- 2.0.20 2004/05/10
787 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
789 SSL comstack now uses yaz.pem certificate file on server side
790 by default. Certificate filename can be configured by calling
791 comstack function cs_set_ssl_certificate_file before cs_bind is used.
793 Fix bug regarding multiple calls to ZOOM_connection_connect.
795 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
797 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
798 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
800 ZOOM now allows inspection of X509 peer certificate for verification.
801 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
803 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
804 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
805 as "modular" but it simplifies things.
807 Added cs_get_peer_certificate to that returns peer X509 PEM.
809 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
810 NULL if SSL is unavailable.
812 Documentation about MARC decoding tools.
814 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
816 --- 2.0.19 2004/03/30
818 Rename CHANGELOG to NEWS to follow GNU style packing.
820 Fix bug with missing initialization of member in init_diagnostics.
821 This bug affects threaded version of GFS server.
823 --- 2.0.18 2004/03/20
825 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
828 Ensure zlib.dll is packed with Windows install.
830 --- 2.0.17 2004/03/17
832 Fix encoding of xsd:string to use text instead of CDATA.
834 Fix endless loop in CQL parser with unbalanced ".
836 Use a more compact way to store MARC-8 conversion tables.
838 --- 2.0.16 2004/03/16 Debian only
840 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
843 Update CQL parser to use new CQL 1.1 modifiers for booleans and
848 --- 2.0.15 2004/03/01
850 Another fix for decoding of XML packed records.
852 --- 2.0.14 2004/02/25
854 Fixes for Chunked encoding. White space not ignored after length spec.
856 Update NS and use default NS for SRW diagnostic elements.
858 --- 2.0.13 2004/02/23
860 Implement ZOOM_resultset_cache_reset which resets record cache.
862 Implement ZOOM_resultset_sort which sorts a result set.
864 Implement chunked HTTP transfer.
866 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
868 --- 2.0.12 2004/02/16
870 Added member 'schema' to bend_explain_rr structure so that backend
871 can specify explain record identifier. Defaults to Zeerex 2.0.
873 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
875 --- 2.0.11 2004/02/16
877 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
880 Added init command for yaz-client which sends "extra" init request.
882 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
883 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
885 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
887 Make ZOOM error code for "invalid query".
889 Fixed compilation for SSL which wasn't properly enabled for all platforms.
891 --- 2.0.10 2004/02/05
893 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
896 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
898 Added option -p <file> to make Generic Frontend Server to write PID file.
900 Added option -D to put Generic Frontend Server in background on its own.
902 Make ZOOM C recognize option "password". If unset, "pass" is used
903 (for backwards compatibility).
905 Fixed a bug in Generic Frontend Server that could make it crash if a
906 client sets characterSetNegotation bit, but didn't pass negotiation stuff
909 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
910 Must be issued before open, in order to be in effect.
912 --- 2.0.9-6 2004/01/12 Debian/Windows
914 Make the SRU server more picky WRT unknown params, etc.
916 Bug fix: ZOOM scan response didn't return displayTerm - when present.
918 New YAZ client command, options, that sets Z39.50 options.
920 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
921 options from a string of tokens (one token for each option bit).
923 Update SRW diagnostic code messages.
925 --- 2.0.9-5 2004/01/07 Debian/Windows
927 Handle user defined stylesheet for SRW/SRU.
929 --- 2.0.9-4 2004/01/06 Debian/Windows
931 Fix bug in decoding of Content-Length.
933 --- 2.0.9-3 2004/01/06 Debian/Windows
935 Fix a bug with decoding of XML packed records.
937 --- 2.0.9-2 2004/01/05 Debian only
939 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
941 Fix bug in SRW/SRU diagnostics decoding.
945 Fixed bug in Generic Frontend Server which could drop records exceeding
946 preferred message size. Reported and fixed by Irina Dijour.
948 Fixed calculation of package size for structured records in Generic
949 Frontend Server. Reported and fixed by Irina Dijour.
951 Fixed namespace for SRW/SRU diagnostics.
953 Fixed SEGV in yaz-client that occured for HTTP connection errors.
957 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
958 this version is incompatible with version 1.0 and older YAZ SRW/SRU
961 CQL changes to reflect recent changes to the specification:
962 * Documentation talks about context sets instead of index sets.
963 * Documentation talks about indexes instead of qualifiers.
964 * The CQL-to-PQF transformer's configuration file now uses
965 "index.set.name = <attributes>" instead of the old form
966 "qualifier.set.name = <attributes>". (Both forms are still
967 understood but the latter is deprecated.)
968 * CQL terms with no explicit index specified are now interpreted as
969 cql.serverChoice instead of srw.serverChoice (which of course
970 behaves exactly the same.)
974 MARC conversion can now generate ISO2709 output in another
975 character set. yaz-marcdump uses this facility if you invoke it
978 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
979 functions from there can be used from C++.
983 Frontend server now transfers memory from decoded packages to stream
986 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
987 references to show up.
989 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
990 the ZOOM Abstract API. The older names for the same options are still
991 also supported for the benefit of old applications.
993 ZOOM-C supports "implementationId" and "implementationVersion" options
994 to go along with "implementationName". These allow the user code to
995 specify identification strings to be sent to servers.
996 Add OID for the new ExtLite attribute set.
998 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
999 as requested/supplid by Ere Maijala <ere@atp.fi>
1001 For generic frontend server, reverse the order of
1002 "toolkit-supplied / application-supplied" strings sent as implementationId,
1003 Name and Version. Also, remove the spaces around the slash. This brings
1004 the GFS in line with the behaviour of ZOOM-C on the client side.
1006 Add function ZOOM_scanset_display_term.
1008 yaz-client shows scan displayTerm if present.
1010 Utility yaz-iconv is now installed by default along with the man page
1013 Extend configure check for OpenSSL to use pkg-config where available (such
1016 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1017 server to specify uid/gid/mask for socket using the format
1018 unix:[user=uid,][group=gid,][umask=mask,]file=path
1019 If file= is omitted the existing format is assumed, e.g.
1021 in which case the mask is 0666 (rw for everybody).
1023 Major restructure of YAZ source. All source in libyaz is in src directory.
1024 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1025 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1027 Added man page for utility yaz-marcdump (used to be called marcdump).
1028 yaz-marcdump is installed by 'make install'.
1030 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1031 of incoming package failed.
1033 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1035 Change prototype of odr_perror: add const to message string.
1037 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1039 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1040 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1041 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1042 DNS lookup. There should not be any compatibility problems with this
1043 assuming that blocking=1 or 0 is used.
1045 Fix bad reference in UNIX comstack in function cs_addrstr.
1047 Fix for compilation on AIX.
1049 The generic front-end server (server/seshigh.c) now supports returning
1050 Init diagnostics to the client in User-information-field, in
1051 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1054 --- 2.0.4 2003/09/04
1056 Allow any CQL relation (not just all,any,exact,scr).
1058 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1059 that features the same UI.
1061 Implemented command update0 in YAZ client which is equivalent to
1062 update but uses old of Ext Update ASN.1.
1064 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1065 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1066 Previously no OID was used for this info.
1068 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1069 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1070 returns 'malformed search term' otherwise.
1072 SortResponse member resultCount now set to NULL in sort handler of
1075 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1078 Add three new utility functions for translating OIDs between various
1079 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1080 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1081 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1082 char *oid_to_dotstring(const int *oid, char *oidbuf);
1083 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1085 Reverted modifications for ES Update definition for z_IU0Update
1086 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1087 is back to YAZ 2.0.2.
1089 String value attributes for CCL parser.
1091 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1092 which their FirstSearch server returns in Init responses, sometimes
1093 carrying useful diagnostic information when Init fails. This has the
1094 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1095 "z39.50/oclcui.asn", where its definition is somewhat different from
1096 what OCLC document on their web-site, as required to interoperate with
1099 Support for anonymous authentication in yaz-client. Use the command
1102 * Fix the OID of the Index Data-local "admin" Extended Service from
1103 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1104 the 1000, which indicates a locally-defined OID, was a mistake.
1106 --- 2.0.3 2003/06/20
1108 Fix CCL directive @case handling so that it affects string match for
1109 both CCL keywords and qualifiers.
1111 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1112 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1113 Decoder has been updated with ASN.1 changes as listed in
1114 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1115 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1116 z_IUUpdate, remains unchanged.
1118 ZOOM_record_get may now return a record in a specific character set.
1119 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1120 "from" is the character set of record as returned by target. "to" is
1121 the character set to be returned. If omitted, "to" is UTF-8.
1123 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1125 New ODR utility, odr_getelement, which returns name of element for
1126 which encoding/decoding failed.
1128 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1129 in cases where a required element was omitted.
1131 Bug fix: some MARC8 sequences were not converted.
1133 New ZOOM option "step" which specifies number of records to be
1134 retrieved in one chunk. Used in conjunction with "start" and "count".
1136 SRW support for yaz-client. Use scheme http: to use it, e.g.
1139 yaz-client no longer does (un)intelligent character set conversions
1140 by default. Can be enabled with charset and marc_charset commands.
1142 xmalloc trace fix for 64-bit systems such as DEC alpha.
1144 Solaris 2.6 compile fix.
1146 New function, cql_strerror() translates SRW error codes, as returned
1147 by cql_transform_error(), into human-readable English strings. Used
1148 in yaz-client diagnostics when appropriate.
1150 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1151 converts it into a type-1 query which is sent to the server. This
1152 makes CQL available for use with all Z-servers, as opposed to the tiny
1153 minority that can handle CQL queries themselves.
1155 --- 2.0.2 2003/04/28
1157 New Debian package layout similar to the Redhat Package layout.
1159 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1160 and search result respectively.
1162 --- 2.0.1 2003/04/25
1164 Redhat package is now several packages: libyaz (runtime libraries),
1165 libyaz-devel (development and documentation, and yaz (utility programs).
1166 Package spec file by Morten Bøgeskov.
1168 New member 'schema' in struct bend_fetch_rr which the name of requested
1169 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1170 handler MAY set this to reflect the schema of the returned record.
1172 New member 'display_term' in struct scan_entry. GFS now sets member entries
1173 and allocates scan entries to be filled by user scan handler. In previous
1174 version, entries member was allocated by the scan handler. That still works,
1175 but the GFS will ignore member display_term - assuming it was NOT set by
1176 the handler. The fact that the GFS now allocates the entries both allows
1177 for new members and makes a scan handler easier to write.
1179 Fix CQL lex buffer overflow.
1181 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1182 SRU default recordPacking is string.
1184 SRU protocol support for frontend server.
1186 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1188 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1190 Added scan for the ZOOM shell (zoomsh).
1194 * String Identifers for Schemas (Amendment 5).
1195 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1196 Old definition for schema
1197 Odr_oid *schema; /* OPT */
1202 Z_InternationalString *uri;
1203 #define Z_Schema_oid 1
1204 #define Z_Schema_uri 2
1207 * resultCount parameter to Sort Response (Amendment 1).
1208 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1210 Support for SRW 1.0 over HTTP. This is an optional feature and
1211 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1214 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1215 on the same port. SRW SearchRetrieveRequests are mapped
1216 to bend_init,bend_search,bend_fetch,bend_close.
1218 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1220 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1221 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1223 ZOOM connections are SRW based if schem http is used for hostname
1224 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1225 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1227 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1228 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1229 distance=n, order=true/false, relation=le, prox unit=word. If
1230 n is omitted, distance 1 is used.
1232 Fixed problem with C compiler include path in wrong order.
1234 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1235 on Solaris. Patch from Ko van der Sloot.
1237 New MARC decode API. All new functions operate on a yaz_marc_t
1238 handle. The most important new functions are: yaz_marc_create,
1239 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1240 decode and destroy respectively. Decoder can produce formats
1241 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1242 include/yaz/marcdisp.h.
1244 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1245 to UTF-8, UCS-32, wchar_t or Latin-1.
1247 * Prototypes for yaz_iconv_-functions moved to separate header
1248 include/yaz/yaz-iconv.h.
1250 Make a few private functions 'static' in unix.c. This prevents
1251 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1253 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1254 are set when Init Response is received.
1256 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1257 but returns diagnostic set as well.
1259 New function yaz_strerror which is a portable wrapper for
1260 strerror/strerror_r/GetLastMessage.
1262 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1263 is returned for MARC. If type is "oai", then OAI MARC is returned.
1265 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1268 --- 1.9.2 2002/11/26
1270 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1272 Fix bad race conditions on SIGTERM and terminate gracefully in
1275 Move retrieval (data1) module to Zebra since nobody seems to be
1278 Add GRS-1 render for ZOOM using same format as yaz-client.
1280 --- 1.9.1 2002/10/05
1282 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1284 Fix broken ESpec handling in data1 module.
1286 SGML reader parses comments and makes them part of the data1 tree.
1288 Added several type casts so that YAZ compiles as C++ code.
1290 ZOOM didn't handle PDU encoding failures properly.
1292 Added more Bib-1 diagnostics (approved extensions).
1294 GNU configure: better check for iconv.
1296 More portable use of accept, getpeername. Check for socklen_t. Use
1297 int/size_t if socklen_t is not defined.
1301 PQF parser rejects bad queries - including those with extra
1302 characters in them. PQF parser used to silently ignore that.
1303 Cleaner API for PQF added, which allows you to get detailed
1304 error information for bad queries (see yaz/pquery.h).
1306 Fixed bug in ZOOM_record_get for type "database".
1308 Implemented mini iconv library supporting conversions between
1309 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1311 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1313 --- 1.8.9 2002/08/20
1315 Fixed ZOOM C record cache so that preferredRecordSyntax and
1316 elementSetName is used to check for already fetched records.
1318 --- 1.8.8 2002/08/02
1320 Added three members in bend_initrequest structure to facilitate
1321 character set negotiation.
1323 Fixed a bug in frontend server that could cause indefinite
1324 loops under rare conditions.
1326 Revised character set utilities (charneg.h) so that encoding
1327 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1329 For PQF, directive @term <type> sets term type for Scan/Search.
1330 Here <type> is general, string, numeric, null. The term type
1331 is inherited - just like @attr.
1333 New call odr_set_charset that sets character set conversion for
1334 international-strings on a ODR stream. Prototype is:
1335 int odr_set_charset(ODR o, const char *to, const char *from);
1336 The InternationalString is still represented as C string in YAZ
1337 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1338 won't). On the protocol level, you can use any encoding.
1340 Support for UNIX sockets in ZOOM.
1342 Solaris recv sometimes returns errno == ENOENT. It is treated as
1343 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1345 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1346 both client and server. Code by Morten Bøgeskov.
1348 --- 1.8.7 2002/05/22
1350 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1351 that they can be used directly from Visual Basic. You must recompile
1352 your windows APP if you're using ZOOM.
1354 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1355 Commands "lang" and "charset" sets language and character set respectively.
1356 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1357 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1359 Attributes from multiple CCL fields may be OR'ed rather than merged
1360 using directive "@field or". Fields are still merged by default -
1361 equivalent to "@field merge".
1363 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1366 Fixed bug in zget for parameter ExtendedServicesResponse.
1370 --- 1.8.6 2002/03/25
1372 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1374 Client displays USR.1:SearchResult-1 (hits per term).
1376 Additional Search Info for search in Generic Frontend Server.
1378 Fixed CCL parsing of "field=s".
1380 WIN32 installer - using the excellent NSIS software from nullsoft.
1382 Fixed CCL parsing of "field = - <number>".
1384 Added function yaz_marc_decode that decodes MARC for line mode
1385 display or XML (similar to that used by JZKit).
1387 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1388 Z39.50. But ISO/ILL was, however.
1390 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1391 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1393 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1394 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1396 --- 1.8.5 2002/02/03
1398 New YAZ client features: Command completion and new commands:
1399 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1400 Code provided by Jacob Poulsen.
1402 New call oid_trav, that visits all registered OIDs via callback.
1404 Function ZOOM_record_get now returns const char pointer rather than
1405 void pointer. It saves a lot of type casts.
1407 For YAZ client, command "auth" now allows you to set authentication
1408 in IdPass style. It is enabled when three tokens are given - order
1409 is user, group and password.
1411 Fix memory leaks in MARC record handling for ZOOM.
1413 New option for YAZ client, -k <kilobytes> that sets
1414 maximum record size. Similar to -k option for generic frontend
1415 server and yaz-ztest.
1417 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1419 Prefix query parser reports "fail" when bad attribute set is given.
1421 Fix in MARC decoder. Proximity logging. Fix for attribute set
1422 in scan handler for server. Patches by Shigeru Ishida.
1424 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1427 Configure option --with-openssl=<dir> now works when a directory is
1428 specified. Patch provided by Morten Bøgeskov.
1430 New option for YAZ client, -u <auth>, that sets authentication.
1432 ZOOM fix: error information was sometimes "missing", since error
1433 was cleared/reset too when it shouldn't.
1435 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1437 --- 1.8.4 2002/01/04
1439 Scan for ZOOM API. New object ZOOM_scanset. New functions
1440 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1441 ZOOM_scanset_destroy.
1443 New ZOOM function, ZOOM_connection_last_event, that returns type
1444 of last event (such as "receive data", "send data", "apdu received",
1447 New ZOOM option, schema, that specifies schema for retrieval.
1449 New CCL feature. Qualifiers can be aliases for one or more
1450 other qualifiers (if more than one is given, OR is used).
1452 ZOOM uses named result sets if target supports it.
1454 Two new YAZ client commands: . (dot, which sources a script of YAZ
1455 client commands), and ! (to execute shell command.). Implemented
1458 Working on Debian packages.
1460 --- 1.8.3 2001/11/19
1462 YAZ client enables named result sets only if target supports it.
1464 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1466 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1467 with key="host" to get same result.
1469 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1470 Function Z3950_resultset_record(s) returns references to records
1471 "owned" by resultset. To become owner use Z3950_record_clone.
1473 Function z_ext_record handles Extended Services. Thanks to
1476 --- 1.8.2 2001/11/12
1478 CCL Parser fix: ignore token comma when dealing with and-lists.
1480 Documentation updates for COMSTACK.
1482 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1483 Changed prototype Z3950_records. For some functions, int parameters
1484 were changed to size_t.
1486 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1489 New MARC decode/display function, marc_display_exl, which properly rejects
1490 non-ISO2709 records. YAZ client uses it.
1492 --- 1.8.1 2001/10/29
1494 Fix bug: local attribute set wasn't set correctly in PQF strings.
1498 * Old Z39.50 codecs no longer supported.
1500 Added ZOOM C binding. See http://zoom.z3950.org/
1502 Renamed states for COMSTACKs to avoid confusion with events.
1504 Implemented cs_look and proper cs_rcvconnect.
1506 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1508 Configure detects POSIX threads on OpenBSD.
1510 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1511 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1513 When error is returned from present handler, non-surrogate diagnostic
1514 is returned in present response (and fetch handler is no longer called).
1516 * Minor adjustments to pquery parser (PQF). Token characters may be
1517 escaped by using backslash (C-style).
1519 PQF parser allows string attribute values to be specified. For @attr,
1520 non-numeric characters after the equal-sign are treated as strings
1521 (e.g. @attr 9=title).
1523 CCL trunction character may be defined (@truncation in file)
1525 * function zget_ExtendedServicesRequest sets waitAction to
1526 waitIfPossible (was wait).
1528 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1531 CCL operator names may be set in field definition files (CCL_bibset).
1532 See ccl/bib1 for an example.
1534 Fixes in ASN.1 compiler for C++ compatibility.
1536 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1537 and "op_or" to avoid conflict with C++.
1539 Fixed problem with GNU readline detection on Redhat 7.0.
1541 Added step-size for Scan backend handler.
1543 Fixed bug that made the frontend server crash when no attribute
1544 set was specified for scan.
1546 Front-end server automatically switches to original working directory
1547 when installed as an NT service. Previously -w had to be specified to
1550 Added extended attributes for retrieval module (data1), so that data1
1551 records carry d1_readXML/SGML attributes. d1_read also supports
1552 null-data rules ( <tag/>)
1554 On UNIX when POSIX threads are available, a separate library libyazthread
1555 is created. Programmers should link with that library and the yaz library
1556 when using threads. The reason for the split was that some applications
1557 on Linux, such as Apache, doesn't work well when using shared objects that
1560 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1561 (or any frontend server) in SSL mode by specifying ssl: followed by
1562 address. Only tested on UNIX.
1564 Added feature for CCL module. Virtual structure s=al or s=ol generates
1565 and-list and or-list respectively instead of phrase search.
1569 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1570 log_mask_str. This was done to avoid name conflicts with other libraries
1571 (such as other PHP extensions).
1573 Added raw OID member for preferred record syntax (request_format_raw)
1574 and returned record syntax (output_format_raw) for backend fetch method.
1576 Config file yaz-config now accepts options so that it returns specific
1577 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1579 Shared library support for UNIX using GNU libtool.
1581 * Modified backend interface. Request/Response struct's replaced by
1582 one read/write C struct. For example bend_fetchrequest and
1583 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1584 Every handler - even search has to be registered in bend_init
1585 handler. This means that the YAZ library no longer refers to
1586 external functions and it makes it possible to make the whole
1587 thing a single DLL/SO.
1589 Added Segment handler for backend server.
1591 Added Zmbol/Zebra administrative functions to YAZ client.
1593 Threaded frontend server on UNIX (when POSIX Threads are available).
1594 Starting the server with option -T enables multi-threading.
1598 Added configure option --enable-comp/disable-comp to control use
1599 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1600 located in sub directory asn.
1602 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1603 in ${exec_prefix}/bin along with the other programs yaz-client and
1606 GNU automake used to maintain makefiles.
1608 Added several OID's.
1610 Changed retrieval module so that we can load records with no abstract
1611 syntax defined. Tagpaths in these records are fully composed of string
1614 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1618 On UNIX, the generated makefile now supports a proper 'make install'.
1619 The prefix can be set via GNU configure to set the install location
1620 (default is /usr/local).
1622 * YAZ programs client and ztest were renamed to yaz-client and
1623 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1624 locations, such as /usr/bin,/usr/local/bin,etc.
1626 * YAZ Header files were moved from include to include/yaz. YAZ Header
1627 files are referred to as include <yaz/log.h> rather than <log.h>.
1628 The YAZ include path (-I ..) is therefore the same as before. Programmers
1629 should update their #include statements or use -Ipath/include/yaz
1630 instead. The main motivation for doing this change is that YAZ header files
1631 can be installed in "standard" locations /usr/include,/usr/local/include
1632 without introducing conflicts, since ALL YAZ header files are stored
1633 in subdirectory yaz (under /usr/include for example).
1635 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1636 rather than project/workspace files. We switched because project files
1637 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1640 Changed name of logging function, logf, to yaz_log, to prevent name
1641 clash with some math-log functions. The YAZ header log.h defines logf
1642 to yaz_log (#define) so there should be no incompatibilities by this
1645 Added bend_start/bend_stop handlers for server. These handler are
1646 called on start/stop of server. For windows they are called whenever
1647 a service is started/stopped.
1649 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1650 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1651 in util/yc.tcl. The auto-generated C code structures are, in a few
1652 cases, incompatible with the old decoders. There are differences in the
1653 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1654 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1655 The preprocessor variable ASN_COMPILED is defined when the compiled
1656 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1657 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1658 wish to use the old encoders/decoders you can specify --disable-yc
1661 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1662 version so that it supports both new - and old version of DB Update
1664 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1665 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1666 change. The name parameter can be set to 0 in which no name is specified
1667 for the construction. The macros odr_implicit and odr_explicit sets name
1668 parameter to zero for the construction involved. New macros
1669 odr_implicit_tag and odr_explicit_tag are similar to the others,
1670 except that a name parameter is added. For programmers' that don't use
1671 ODR they probably only need to change the call to z_APDU and z_External.
1673 Added access control facility by interfacing the TCP wrapper library.
1674 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1675 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1676 name of the daemon and enables the access control as specified in
1677 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1679 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1680 den Dool <H.M.vdnDool@kub.nl>.
1682 Added reference ID parameter to most functions in server API - refer
1683 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1685 Changed name of ccl library to libccl.a (was ccl.a).
1687 Fixed bug in decoder for Explain (Category TargetInfo).
1689 Added support for GNU readline in client. Thanks to Jacob Poulsen
1690 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1692 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1693 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1694 IMPLEMENTATION! This change was made to the development version before
1695 the ZIG decided to retract the amendment. If any users MUST be
1696 compatible with the original Update definition, PLEASE CONTACT US, and
1697 we will include a separate definition corresponding to the old Update
1698 ES. Note that because of the change to the ASN.1 of the
1699 TaskPackageRecordStructure we cannot define a single structure that
1700 will support both versions.
1702 * Added const modifier to buffer parameter for some ODR/BER encoding
1703 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1704 completeWAIS, odr_dumpBER.
1706 Fixed bug in client.c which caused a crash when a scanResponse didn't
1707 contain positionOfTerm.
1709 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1710 * will cause an error in a client if a non-YAZ target sends both a
1711 * list of Scan entries and non-surrogate diagnostics.
1713 Retrieval module enhancements. Tag sets may be typed in the reference
1714 to it. From the .abs-file the "tagset" directive takes a third optional
1715 integer type for the tag set referenced. From a .tag-file the "include"
1716 directive takes a third optional type as well. The old "type" directive
1717 in the tag set itself is still recognized but acts as the default type
1720 Backend interface change. Individual Scan terms returned from bend_scan
1721 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1722 in include/backend.h.
1724 Retrieval module enhancements. Multiple tag sets and attribute sets may
1725 be specified in abstract syntax specs. Revised the error/warning for
1726 logging messages reported by the retrieval module when reading the
1729 Object Identifier system (oid_..) changed. The API is backwards
1730 compatible but the oid-routines now allocates new OID's when needed.
1731 Raw OID's may be specified in oid_getvalbyname.
1733 YAZ now uses GNU configure to generate Makefile(s).
1735 * Minor changes in some of the member names of DeleteResultSetRequest and
1736 DeleteResultSetResponse. See include/proto.h.
1738 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1739 and added member 'languages' in TargetInfo (which was missing).
1741 Changed the way attribute sets are handled in the retrieval
1742 module. These are now cached, just like the abstract syntaxes
1745 Changed YAZ so that it links with compiled ASN.1.
1747 Added Explain-schema definitions and mapping routines. The following
1748 Explain categories have been implemented: AttributeDetails,
1749 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1751 Fixed minor bug in Windows version of Server Library.
1753 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1755 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1757 Added EXTERNAL: UNIverse Resource Report (non-standard).
1759 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1760 ENUMERATED and SET OF.
1762 * Added 'const' to some of the char pointer arguments for the
1763 functions, data1_read_node, data1_getelementbytagname,
1764 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1767 Fixed bug in data1_insert_taggeddata - the last_child member of
1768 parent wasn't initialised.
1770 * Changed data1_read_record and data1_read_node so that the supplied
1771 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1772 doesn't refer to any parts of the "SGML"-buffer.
1774 Fixed bug in server library (Windows version of statserv_remove).
1776 * Changed code so that it compiles as C++. The type definition
1777 of Odr_fun which is a member of Odr_arm was changed. The result is,
1778 that an explicit typecast is needed for the fun pointer when
1779 using Odr_arm - as in:
1780 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1782 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1784 Implemented the new structured date and time definition as approved
1785 by the ZIG. Added schemaId element to the specificTag in Espec-1
1786 (also approved at the last ZIG). Thanks to RVDM.
1788 Added some Object identifiers (RVDM).
1790 Changed the Update Extended Service (RVDM).
1792 Added command "refid" to client which specifies referenceId for
1793 the following requests.
1795 Implemented extended service handling for server. See ztest.c
1796 for an example as well as backend.h. New handlers are registerd
1797 in the Init handler.
1799 * Changed interface for sort in server.
1801 Added new members to statserv_options_block. It allows a server
1802 to read options from another source than just the command line. Thanks
1803 to Charles Woodfield.
1805 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1806 renamed to zboolean. Some C++ compilers complained about the name.
1808 Minor changes to gils.abs. Added index 's' (sort) on title
1809 and date/time-last-modified.
1811 --- 1.4pl2 1998/1/30
1813 Fixed bug in server library regarding inetd mode (-i). This bug
1814 was introduced by release 1.4.
1816 --- 1.4pl1 1998/1/29
1818 Added sort facility in client and backend server interface.
1820 Fixed problem with dependencies in Makefile(s).
1822 Fixed bugs for encoders/decoders of extended services and
1825 Implemented sub-tree feature for schemas. Sub-trees are
1826 referenced in *.abs-files. See explain.abs for an example
1827 of the use of this feature.
1829 Modified bib1.att; local attributes for ANY didn't include
1830 ANY itself (only affects use of the retrieval module).
1832 Fixed bug in plain SGML reader in function data1_read_node:
1833 tags with prefix "var" was incorrectly interpreted as variants.
1835 Added feature "sub-schemas" to enable references to - and definitions
1836 of - group of elements.
1838 * Removed member parent from type data1_element (in data1.h).
1840 Implemented function odr_nullval() that returns the value of
1843 * Removed member num_children from data1_node (in data1.h).
1845 Made NT service interface part of the server library. The
1846 function statserv_main uses the NT service when required and
1847 calls the statserv_start / statserv_close routines.
1849 Routine zget_SearchRequest and zget_PresentRequest fills
1850 resultSetName/Id member with "default" instead of "Default".
1852 Fixed memory leak in server. Request queue member wasn't freed.
1854 Fixed nmem_exit so that memory is freed.
1858 Revised the CCL parser utility to be thread safe.
1860 Added function, oid_ent_to_oid, to replace the function
1861 oid_getoidbyent, which is not thread safe.
1863 * Added nmem_init and nmem_exit to initialize and release
1864 NMEM resources. Function nmem_init should be called once in the
1865 initial thread before NMEM/ODR is used. statserv.c and client.c
1866 have been changed accordingly. The change was necessary to make
1867 NMEM thread safe. The NMEM memory pool is shared amongst threads
1868 in a process. Unix-based applications will still work fine without
1871 Added NT Services interface for the the Z39.50 (statserv) Server.
1872 Refer to the ztest.c source on the usage.
1874 Windows 95/NT port using MSVC5.0. Project files are included in the
1877 * Defined new 'global' handle for the retrieval (data1) system. The
1878 new handled, data1_handle, describes the state of the data1 system.
1879 This handle is passed as first argument to virtually all
1880 data1 related routines. The functions data1_create and data1_destroy
1881 creates and destroys a data1 handle respectively.
1883 Added ODR encode stream member to all backend request structures
1884 init, search, scan etc. This stream should be used to allocate all
1885 memory used for the response when thread safe operation is needed.
1887 Changed the comstack utility, cs_addstr, to be thread safe. The
1888 returned hostname string returned by the function is now part the
1891 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1892 function. The cs_straddr takes a COMSTACK handle as argument, so this
1893 function must be used after cs_create and before bind/connect.
1894 This function is thread safe.
1896 Moved test server to 'ztest' directory - generic server code still
1897 in 'server' directory.
1899 Made prefix query (pquery.c) utility thread safe.
1901 Added new function modifier YAZ_EXPORT to 'export' public DLL
1902 functions when using windows (see include/yconfig.h).
1904 Added definitions to the OID database (util/oid.c) (RVDM).
1906 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1908 Added call to ccl_rpn_delete in client program.
1910 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1911 release of RPN structure.
1913 Added support for C++, headers uses extern "C" for public definitions.
1914 With input from RVDM.
1916 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1917 Thanks to Ronald van der Meer (RVDM).
1919 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1921 Added support for private extensions to the OID database
1922 (oid_setprivateoids()). Thanks to RVDM.
1924 Added optional, physical ANY (key replication)
1926 Fixed null-reference problem in GRS-1 output filter.
1928 Proximity operator added to Prefix Query Format (PQF).
1930 In test client command "base" accepts multiple databases.
1932 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1936 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1938 Smallish bug-fixes in the new encoders/decoders (explain).
1940 Bug fixed in DeleteRequest.
1942 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1944 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1946 Added SOIF syntax (using private OID for now) to retrieval module and client.
1948 Added Update extended service.
1950 Added SearchResult-1 additional info structure.
1952 Added optional CCL (ISO8777) interpreter as separate module. Available
1955 --- 1.2 1996/6/10 (1st anniversary release)
1957 Added Summary record syntax. Lightly tested.
1959 Added OPAC record syntax. Untested.
1961 Added ResourceReport service encoders/decoders. Untested.
1963 Fixed bug in z_Unit - wrong tagging on unitSystem.
1965 Fixed bug in the DiagRecs decoder.
1967 Added options for max PDU size and session timeout to frontend-server.
1969 Added documentation of query-language parsers and other supporting utilities.
1971 [frontend-server] Added Attribute set to the bend_scanrequest API.
1973 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1974 surrogate diagnostics were generated.
1976 [retrieval] Allow multiple local values for attribute.
1978 [retrieval] Allow multiple attributes per element in .abs files. index type.
1980 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1982 --- 1.1pl2 1996/4/10
1984 Minor changes, mostly specific to Zebra's requirements (retrieval)
1988 Repaired bug in frontend server when running multiple listening
1989 endpoints in dynamic mode.
1991 z_External() now won't break if a known, ASN.1 value comes encapsulated
1992 in an octet-string. The value will pass through unmodified in an Odr_oct.
1994 Added a bit of code to the demo client to decode & display
1995 ASN.1-structured records represented in the octet-aligned branch of
1996 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1998 Added z_ext_getentbyref() to the ASN module. Doc updated.
2000 * Completed the SCAN definition in the ASN module. This may break SCAN
2001 code based on older YAZ-versions at compile-time. The fix is easy -
2004 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2005 under the SCAN definition. Remember to initialize this, server-people.
2007 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2008 that this does not extend to ODR and ASN.
2010 Comstack allows insertion of established socket (primarily for
2011 inetd-operation of servers). Doc updated.
2013 Front-end server can now start from the inetd in TCP mode. Doc
2016 --- 1.0pl4 1996/1/24
2020 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2021 the rank and record number.
2023 Adjustments to the frontend server.
2025 Fixed diagnostic BER dumper. It ignored the file argument.
2029 Various changes to retrieval module.
2031 Changed the union discriminators of the protocol files from enums to
2032 ints paired with #defines.
2034 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2037 *Changed operator in the RPN structure to 'roperator', again to avoid a
2040 Fixed problems in Explain decoders/encoders.
2042 --- 1.0pl2 1995/12/6
2044 Memory bug in log module fixed.
2046 --- 1.0pl1 1995/12/5
2048 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2050 Bug in Explain DatabaseInfo module fixed.
2052 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2056 The shift to v1.0 signals that we now consider the *core* functionality
2057 of YAZ reasonably stable (the core being more or less equivalent to
2058 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2059 tested (Explain not at all - though that will happen soonish).
2061 Minor changes to code to support Windows port.
2063 Various minor changes after we're getting to use GRS-1 & co. more.
2065 Added Espec-1 format.
2067 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2068 of the protocol and it cannot be selected when encoding (maps into 'string'
2069 when decoding). Needed to talk to some servers.
2071 Demo client can request simple element set names.
2073 Added Diagnostic Format encoders/decoders.
2075 Added simple Close handling to frontend server (no hooks for resource
2076 reporting yet), and demonstration client.
2078 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2080 --- 1.0b3 1995/08/24
2082 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2083 handled incorrectly when records were requested in the searchResponse. This
2084 will only affect you if you use the frontend-server.
2086 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2087 Test-client will ask for and print GRS1. Ztest will return dummy records
2090 Added Explain encoders/decoders to the service-level API. Untested.
2092 Added Extended Services: Item Order encoders and decoders to the Service-
2093 level API. Untested. We could use a recent copy of the pertinent bits
2094 of the ILL protocol to add those bits.
2096 Added diagnostic format 1 encoders/decoders to the service-level API.
2099 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2100 odr_cons.c, which causes a more correct output.
2102 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2103 was always set to 0 when no records were requested in the searchRequest.
2105 * Added better external-handling. This shouldn't harm old code that
2106 *encodes* externals. It can break code that looks for a
2107 'single-ASN1-type' representation, since those types that are known
2108 are now decoded immediately. Look at the SUTRS sample code in
2109 seshigh.c and client.c. Documentation updated.
2111 Handling of structured records in bend_fetchresponse. Length -1 marks
2112 structured record, type is deduced from format field.
2114 --- 1.0b2 1995/06/27
2115 Fairly quick maintenance release to add SUTRS support.
2117 Fixed handling of SUTRS records in the demonstration client.
2119 * Added format field to the bend_fetchrequest and bend_fetchresponce
2120 structures of the backend API (frontend server). When the record is
2121 returned, the value of the format field is mapped to an OID. The
2122 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2123 of the record. The special value VAL_NONE in the bend_request means
2124 that no specific format was requested by the client. Documentation
2125 updated accordingly. Test server (ztest) will return a fixed dummy
2126 SUTRS record if your client requests SUTRS.
2128 Documentation updated accordingly.
2130 You can now set external libraries and RANLIB support in the top-level
2134 First public release.
