1 New OID database - with public definitions in oid_db.h. Removed old OID
2 database including the head oid.h and definitions such as enum oid_value
3 and struct oident. The new OID database uses the same string names as
4 before but the 'protocol' is gone. There are now only two representations
5 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
6 converts from string to OID; functions with prefix yaz_oid_to_string
7 converts the other way.
9 Change to emit_term() in CQL-to-PQF query translation: when a term has
10 the /regexp relation modifier, do not process it for leading and
11 trailing "^" and "*", which have quite different meanings in regular
14 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
15 write handlers no longer carries a 'last' parameter. This will make
16 yaz_iconv flush "less" characters. A flush is performed by call to
17 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
19 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
20 removed, because function yaz_query_to_wrbuf does the same.
22 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
23 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
25 Deprecated MARC utility functions removed.
27 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
30 Branch split: YAZ_2_1_55_branch
34 Fix to ZOOM-C so that transparent reconnection is properly handled on
35 connections that are in asynchronous mode.
37 Fixed compilation on OpenBSD 4.0.
39 Large strings in GRS-1 records are now properly displayed in yaz-client.
41 Added character conversion support for "advancegreek"; based on patch from
44 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
45 sequence is met. Before the error was not set so it would be unknown.
47 Adjust yaz-marcdump MARC reader so that it skips until record separator
52 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
53 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
54 fd_set structure used as a bitmask for the FDs to be selected on.
56 Using ACX_PTHREAD macro to check for POSIX threads.
58 Fixed have-vsnprintf check.
62 Fixes for configure on BSD. Bug #900.
64 Added snprintf/vsnprintf wrappers for systems that don't have
65 limits (heavens forbid).
67 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
68 created before all previous tasks were completed and removed from the
69 task queue, the new task could be removed by a mistake.
71 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
73 Implemented pass-through CQL-to-PQF conversions. Bug #861.
75 Fixed bug #832: Problem with MARC/charset in yaz-client.
77 Fixed bug #668: save command line history for yaz-client.
79 Fixed bug #830: pkg-config support.
83 Extended ZOOM result set options with two options that may be read by
84 a client: resultSetStatus and presentStatus with values as specified for
86 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
88 Fixed bug #827: Using SSL fails on Debian etch.
90 Fixed bug #826: Weird looking chars for set of MARC records.
92 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
93 that is treated as an ItemOrder with itemRequest being an XML document
94 external. The value of "doc" is the content.
96 Extended the GFS search facility. New member of bend_search_rr
97 'estimated_hit_count' signals that hits is known to be an estmate
98 (higher or lower than real hit count). New member 'partial_resultset'
99 signals that the search was partial (hit count is lower or equal than
100 real hit count). For Z39.50, the information is stored in resultSetStatus
101 member of SearchResponse APDU. For SRU, the information is signalled
102 via SRU diagnostic 59: "Result set created with valid partial results
105 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
107 --- 2.1.46 2007/01/13
109 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
111 Added ZOOM_connection_peek_event.
113 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
114 the following new functions:
115 ZOOM_event_nonblock, ZOOM_connection_process,
116 ZOOM_connection_get_{socket,mask,timeout},
117 ZOOM_connection_fire_event_{timeout,socket}.
118 The existing blocking event handler, ZOOM_event, is a wrapper for the
119 + blocking ZOOM_event_sys_{poll,select}.
121 Implemented function ccl_xml_config which parses XML version of CCL
122 configuration (bug #798).
124 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
126 Added timings utility (yaz/timing.h)
128 --- 2.1.44 2007/01/03
130 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
133 Fixed bug #779: Rotation of apdu.log fails.
135 Fixed for character set conversions:
136 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
137 Honor G1 set in MARC-8 decoding.
139 --- 2.1.42 2006/12/17
141 Fixed bug #775: char conversion does not handle Alternative UTF-8
144 Implemented function yaz_marc_read_line which parses MARC line format
145 records. There is a wealth of formats out there. So far, this function
146 reads line records produced by yaz_marc_write_line.
148 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
149 more generic and easier to remember(!) options: -i format and -o format
150 which specifies input format and output format respectively - where
151 format is one of "marc", "marcxml", "line", "marcxchange".
153 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
154 does not print anything except warnings for records.
156 For yaz-marcdump, added support for MARC split into files (-s) with a given
159 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
160 spec, at http://www.loc.gov/standards/sru/record-update/
161 This has changed the binary layout of the following structs:
162 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
163 bend_update_rr . Patch by Ko van der Sloot.
165 Added GFS utility function bend_assoc_is_alive which returns 1 if
166 association is still alive (client is connected); 0 otherwise (client
167 closed connection). This allows busy servers to stop working for
170 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
171 been a separate piece of software. This version of ziffy has been modified
172 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
174 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
176 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
177 Client code may now interrogate options such as "init_opt_sort" to
178 find out whether the server claims to support various options.
180 --- 2.1.40 2006/11/27
182 Added utilities yaz_{set,get}_esn to set/get element set name from
185 Removed the build of libyazthread.la. The libyaz.so is the threaded version
186 of YAZ and has been so since YAZ 2.1.10.
188 Implemented ZOOM_record_error which returns error information for
189 record (surrogate diagnostic).
191 --- 2.1.38 2006/10/31
193 Updates for SRU Update by Ko van der Sloot:
194 1. Changed name from "operation" to "action"
195 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
196 versions in the code, marked as 'backward compatible'.
197 3. Added diagnostics for SRU Update.
199 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
201 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
203 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
205 For GFS, fixed problem with SRU diagnostic 'First record position out of
206 range' being issued for 0 hits.
208 zoomtst10 part of Windows Build.
210 --- 2.1.36 2006/10/13
212 Implemented yaz_filepath_comp which splits a path into file path
213 components (required by Zebra 2.0.3+).
215 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
216 BSD inspired license until now so this should not have any real impact on
217 anybody. See http://www.opensource.org/licenses/bsd-license.php
219 Fixed bug #687: Missing log lines.
221 Fixed bug #678: CQL to PQF translation does not preserve double-quote
224 Fixed bug #689: SRU diagnostics to be added.
226 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
227 whether a connection is idle (no more work do do).
229 --- 2.1.34 2006/10/04
231 Change type of optval from long to int for invocation of setsockopt with
232 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
234 Added support for specifying the max log file size for the Generic
235 Frontend Server. The size is given with option -r.
237 --- 2.1.32 2006/09/21
239 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
241 --- 2.1.30 2006/09/17
243 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
246 Fixed bug in Generic Frontend Server that could cause a server to stop
247 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
249 For the generic frontend server, the maximum record size is used as maximum
250 size of incoming packages (SRU + Z39.50). The value until was previously
251 only used in Z39.50 Init negotiation and, later, in a session controlled
252 sizes of records returned. This is controlled using -k option. It can be
253 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
255 --- 2.1.28 2006/09/04
257 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
260 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
262 New option for yaz-marcdump -lpos=value which allows setting a portion
263 of MARC header to a certain value.
265 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
267 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
268 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
270 --- 2.1.26 2006/08/15
272 Fixed problem with SRU mode type (soap, get, post) for yaz-client
275 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
277 --- 2.1.24 2006/08/08
279 Fixed MARC ISO2709 encoding routines to deal with character set
282 Minor changes to GFS logging. Database included in search request log
285 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
286 cached/multiple records.
288 Shared libraries are built by default on Unix+configure.
290 Changed cql2pqf transformation to use a different evaluation order. The
291 new order is: always, relation, structure, position, truncation, index
292 and relationModifier. Old order was: always, relation, relationModifier,
293 structure, index, position, truncation. Note that the the latter ones
294 override former ones for identical attributes.. The new scheme means that
295 it is possible to override any existing attribute with a relationModifier.
296 And also that it is possible to override everything for the index rule
297 (except the ones listed in relationModifier). No order is perfect but this
298 one, we believe, covers more real cases.. The "always" should have been
299 called "default", since the attributes there can be overridden with all
302 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
303 compilation phase, but also for yaz-config --cflags output. This allows
304 us to have public headers with Libxml2 stuff in them . It should also,
305 eventually, make Libxml2 checks redundant in packages using YAZ, such
308 --- 2.1.22 2006/06/15
310 Changed SRU update structure bend_update_rr so that SRU diagnostics are
311 stored in uri, message and details.. Previously diagnostics were stored
312 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
313 compatibility.. but he's probably the only one affected, so.
315 Added support for CCL, compiled on the client side, in ZOOM-C. This
316 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
317 input; the resulting query objects can be used for for searching with
318 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
320 YAZ' configure searches for OpenSSL by default.
322 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
323 SL_CTX_use_certificate_file. See
324 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
325 for more info. Thanks to Ko van der Sloot.
327 --- 2.1.20 2006/06/02
329 Bug #600: SRU GET, POST support for yaz-client. Introduced
330 command 'sru' which selects method SOAP/GET/POST.
332 Allow missingValueAction to be specified for the sortspec string -
333 function yaz_sort_spec. By default, the missing value action is null.
334 Use ! to specify "abort". Use = followed by stringvalue to specify default
337 Ensured that Present-handler (if defined) is called in GFS before any call to
338 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
339 searchRetrieve requests.
341 Documentation for YAZ is now based on the Docbook XML/XSLT using
342 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
343 is no longer depending on jade/openjade or docbook-to-man scripts.
344 PDF is no longer part of the distribution - but can optionally be
345 made using DSSSL/jadetex or FOP.
347 Added retrieval handling support in Generic Frontend Server to support
348 conversion between MARC/XML as well as XSLTtransforms. See
349 etc/yazgfs.xml for an example.
351 Added Authentication support to Generic Frontend Server in SRU
352 mode. Authentication using HTTP Basic is supported, as is the use
353 of 'x-username' and 'x-password' parameters in the request itself.
355 Added support for a new character set MARC8s identical to MARC8 except
356 that it converts combined characters to single Unicode characters in the
357 Latin-1 range (when possible).
359 --- 2.1.18 2006/04/24
361 ASN.1 compiler 0.4: generates brief Doxygen file header for
362 generated .h/.c files.
364 Utility yaz_iconv now supports conversion to MARC-8.
366 New facilities for the MARC module. The reading - and writing of
367 content are separate methods for the yaz_marc_t handle. The following
368 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
369 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
370 format). Write functions have prefix yaz_marc_write_.. The existing
371 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
372 available. Removed support for OAI-MARC and simplexml (not the
373 simplexml from PHP5).
375 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
376 to be returned for this connection.
378 --- 2.1.16 2006/03/31
380 Allow multiple languages and charsets to be specified with
381 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
382 negcharset iso-8859-1,utf-8
384 Translation of proximity nodes from CQL into PQF now works.
386 Moved to automake 1.8, 1.9.
388 Added function yaz_log_set_handler which allows a log handler to be
389 installed. This handler will be called for all log messages. Output
390 to file is also produced; but that can be disabled by passing NULL
391 fname to yaz_log_init_file.
393 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
395 For SRW (including GFS), accept application/soap+xml as content-type
398 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
399 produces NO stylesheet reference even if a default stylesheet is specified
402 --- 2.1.14 2006/03/14
404 Updated Windows package to include yazd.dll + yazd.lib for the
405 Development component.
407 If the environment variable YAZ_LOG is set, then it is used as a
408 string indicating the default level of logging to use if not
409 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
410 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
411 used as before. So, for example, to omit warnings from YAZ logging,
414 cql_transform() now map structure and other attributes before indexes,
415 so that index-specific structures and other attributes can override
416 defaults. So now a combination of mapping specifications such as:
418 index.dc.date = 1=date-modified 4=5
419 does the right thing.
421 cql_transform() now also respects the "always" mapping specification,
422 which establishes an initial set of attributes to be used for all
423 terms except where overridden by more specific attributes associated
424 with the index, relation or modifier.
426 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
427 which mode to use; one of "post", "get" or "soap" (SRW, default).
429 Fixes for yaz_iconv routines: changed trie-based character set conversions
430 to use only non-negative values for bit fields due to Sun's C compiler not
431 supporting negative values.
433 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
434 sequences where not read correctly. Fix by Rustam Usmanov.
436 Updated win/makefile to use options, settings which makes things
437 compile with VS C 2005.
439 --- 2.1.12 2006/02/01
441 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
443 In ZOOM socket code, use select instead of poll on MacOSX.
445 ZOOM-C now support client-side compilation of CQL into RPN that is
446 sent to the server, enabling CQL to be used against all Z39.50
447 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
448 ZOOM_query object, and submit it using ZOOM_connection_search().
449 The CQL-to-RPN translation uses a configuration file, the name of
450 which must be specified in the Connection's "cqlfile" option.
452 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
453 function, which takes as its start-term parameter a ZOOM_query object
454 (which may have had either CQL or RPN set into it).
457 --- 2.1.10 2005/11/29
459 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
460 GFS to support this as well. Backend handler, bend_srw_update, does the
461 update work. Code contributed by Ko van der Sloot.
463 Allow retrieval of Search Result-1 information in ZOOM by the use of
464 options that are attached to a result set. ZOOM documentation updated
467 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
468 UTF-8 conversion. Patch by Raj Patel.
470 Added option -m to GFS to control formatting of timestamps in log file.
472 Added 'exit' as synonym for 'quit' in yaz-client
474 Added support for specifying SRW resultSetId + resultSetIdleTime in a
475 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
476 for the new members. Patch by Ko van der Sloot.
478 Added support for SRU POST. It is supported for content-type
479 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
481 Do not build the separate Multi-threaded (MT) library libyazthread.la.
482 Instead make the library libyaz.la multi-threaded. Threading as a whole
483 can still be disabled by configure option --disable-threads. Previosly,
484 with older GLIBCs there were problems with MT libs under Apache. This
485 has now been fixed a long time ago.
487 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
490 CQL module modified to be case insensitive for relations/indexes/operations.
492 Fixed bug in CQL transform code: incorrect value relationModifieder
495 Added 'show all' command for yaz-client which retrieves all results
498 Added new yaz-client, xmles, which takes a (private) OID and
499 a document to be sent as an extended service request.
501 Describe new yaz-client commands wait_response and set_auto_wait.
503 Increase TCP/IP listener backlog from 3 (which I am guessing was
504 copied from the SunOS manual entry way back when) so SOMAXCONN, so
505 that the socket will queue as many incoming connections as it's able
506 to handle ongoing connections. In other words, it will never now
507 refuse a connection that it would be able to handle merely because
508 it's not got around to accepting() enough of the pending connections
509 yet. This is the behaviour anyway under Linux, where the listen()
510 argument is ignored; but not under BSD and on systems such as
511 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
512 YAZ-based servers should now be uniform across operating systems in
515 yaz-marcdump uses 64-bit file access on some systems. This is enabled
516 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
517 This allows yaz-marcdump to read large MARC batches (>2 GB).
519 Modified all YAZ source files - except the source which is auto-generated
520 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
523 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
524 corresponding to the existing *_setl() function. These allow option
525 values containing arbitrary valuues.
527 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
528 ZOOM_resultset_sort() in new applications. Its behaviour is identical
529 except that it returns an indicator of whether or not the sort
530 criterion was accepted (0 for OK, -1 for invalid).
534 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
535 MARC output rather than returning "new" buffer.
537 yaz-client warns about unknown init options.
539 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
543 Added support for SRW sort in Generic Frontend Server. Patch
544 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
545 sortKeys - or NULL if none is provided.
547 Fixed bug #307: It was impossible to specify indefinite/no timeout
548 for ZOOM_event. Special timeout value -1 now means indefinite timeout
551 Added support for multiple languages and charsets to be specified in
552 ZOOM. Each charset/language is separated by a blank. If negotiation is
553 in effect in init-response, Option
554 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
555 Code based on patch by Vasiliy Osadchuk.
557 Fixed bug #306: infinite recursion that occurred when calling
558 yaz_log_level_init as the first call (before other log level or
561 Fixed bug in scan handling in front end server: if preferred-Position-In-
562 Response was non-present, a NULL pointer referece was performed.
566 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
567 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
568 now defined for all those error codes. So instead of putting 109 in
569 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
570 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
572 Modified the yaz-marcdump utility to skip garbage bytes between MARC
575 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
577 Program yaz-client now exits and produces an error message if multiple
578 Z39.50 servers are specified on the command line (none or one allowed
581 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
586 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
588 Fixed bug #272: Preserve spacing for CCL terms.
592 Added support for virtual hosts and multiple backend servers for
593 the YAZ frontend server. The configution is XML based and
594 support specificition of CQL to RPN mappings and explain information.
595 See section "Virtual Hosts" in the YAZ manual.
597 Extended OPAC display utility. OPAC display utility renders
598 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
599 to supplement yaz_marc_decode_wrbuf.
601 Fixed a bug in MARC decoder that could caused it to crash for some
602 invalid MARC records. More diagnostics and warnings where added in
603 XML output (warnings, etc are stored in comments).
605 --- 2.0.34 2005/02/08
607 Fixes for UNIX domain sockets. Bug #261.
609 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
611 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
612 Added yaz_marc_subfield_str which defines subfield lead string which is
613 used in YAZ_MARC_LINE format. Default string is blank+$. Added
614 yaz_marc_endline_str which defines end of fields string used in
615 YAZ_MARC_LINE format. Default string is newline.
617 Experimental support for MarcXChange. This format can be produced
618 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
619 http://www.bs.dk/standards/MarcXchange.xsd
621 Added yaz-client commands scansize that sets maximum number of
622 entries to be returned by scan.
624 --- 2.0.32 2005/01/11
626 Added support for SRW scan in yaz-client and Generic Frontend Server.
628 * Added whereInList member to SRW Scan Term.
630 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
632 Fixed NMEM system to return aligned blocks on the smallest boundaries
633 that are suitably aligned for all possible types on the particular
634 architecture YAZ is being built for.
636 --- 2.0.30 2005/01/04
638 Fixed numerious warnings that was issued with newer versions of GCC.
640 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
641 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
644 Make YAZ Generic Frontend Server slightly faster.
646 Enhance (and reduce) logging for Generic Frontend Server.
648 Revert YAZ log system so that it flushes every write operation
649 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
651 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
652 instead of LOG_, due to name clash with syslog(3). LOG_ are still
653 present. New applications should define YAZ_USE_NEW_LOG=1 - this
654 will effectively disable old definitions.
656 --- 2.0.28 2004/11/09
658 Added yaz_log_time_format which specifies log format using
661 Added yaz_log_module_level which returns mask for a module. Value
662 is non-zero mask a if module is enabled; zero if disabled.
664 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
665 in include/yaz/cql.h.
667 Fixed bug #176: Dont throw diagnostics on empty SRU args.
669 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
671 Fixed bug #172: RPM builds does not enable SSL.
673 Doxyfile.in part of dist. Doxyfile generated by configure.
675 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
676 are given and the corresponding component does not exist.
678 Extend CCL documentation in YAZ reference. Describe r=r.
680 --- 2.0.26 2004/10/01
682 Fixed MARC->MARCXML conversion to properly deal with
683 fields, subfields, indicators having non-ASCII characters.
685 Fixed MARC->MARCXML conversion so that ASCII control characters
686 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
689 Added YAZ GFS support for conversion from Z39.50 surrogate
690 diagnostics to SRW surrogate diagnostics.
692 Bug fix: YAZ GFS did not return schema in explainResponse.
694 --- 2.0.25 2004/09/30
696 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
697 now converts recordSchema to elementSetName as well as schema URI.
699 Fixed bug in COMSTACK that prevented HTTP request packages from being
702 --- 2.0.24 2004/09/29
704 Added CCL facility r=r "range" which is similar to r=o "ordered" but
705 does not require white-space before and after the dash in a range, e.g.
706 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
709 Fixed a few AC_TRY_LINK configure tests that did not operate properly
710 due to new GCC removing "redundant" code.
712 Added yaz-client commands scanpos and scanstep that sets preferred
713 position and step-size for scan.
715 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
717 Added CCL utility ccl_qual_buf which parses one or more CCL
718 spec lines in a buffer.
720 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
721 of name and value - ignoring empty lines and comments.
723 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
725 Added odr_get_element_path which returns current element path for an
726 ODR handle. This utility is useful in error handling or user-defined
729 Added ODR_PRINT utility odr_set_stream which is is a more generic
730 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
731 to a write function and pointer to close function. The close function - if
732 non-NULL - will be called during odr_destroy.
734 Fixed bug in CCL parser where truncation char was not removed from
735 right side when truncation=both was in effect.
737 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
740 --- 2.0.23 2004/08/11
742 Fix buffer overrun in CQL parser when dealing with proximity (%).
744 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
745 to UTF-8/UCS conversion is now only based on codetables.xml.
747 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
749 --- 2.0.22 2004/08/06
751 Add support for more "commit changes" in ZOOM (uses Extended Services).
753 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
756 Yet another small fix for configure of SSL.
758 --- 2.0.21 2004/05/14
760 Fix SSL libs for configure when --with-openssl=DIR is given.
762 --- 2.0.20 2004/05/10
764 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
766 SSL comstack now uses yaz.pem certificate file on server side
767 by default. Certificate filename can be configured by calling
768 comstack function cs_set_ssl_certificate_file before cs_bind is used.
770 Fix bug regarding multiple calls to ZOOM_connection_connect.
772 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
774 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
775 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
777 ZOOM now allows inspection of X509 peer certificate for verification.
778 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
780 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
781 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
782 as "modular" but it simplifies things.
784 Added cs_get_peer_certificate to that returns peer X509 PEM.
786 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
787 NULL if SSL is unavailable.
789 Documentation about MARC decoding tools.
791 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
793 --- 2.0.19 2004/03/30
795 Rename CHANGELOG to NEWS to follow GNU style packing.
797 Fix bug with missing initialization of member in init_diagnostics.
798 This bug affects threaded version of GFS server.
800 --- 2.0.18 2004/03/20
802 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
805 Ensure zlib.dll is packed with Windows install.
807 --- 2.0.17 2004/03/17
809 Fix encoding of xsd:string to use text instead of CDATA.
811 Fix endless loop in CQL parser with unbalanced ".
813 Use a more compact way to store MARC-8 conversion tables.
815 --- 2.0.16 2004/03/16 Debian only
817 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
820 Update CQL parser to use new CQL 1.1 modifiers for booleans and
825 --- 2.0.15 2004/03/01
827 Another fix for decoding of XML packed records.
829 --- 2.0.14 2004/02/25
831 Fixes for Chunked encoding. White space not ignored after length spec.
833 Update NS and use default NS for SRW diagnostic elements.
835 --- 2.0.13 2004/02/23
837 Implement ZOOM_resultset_cache_reset which resets record cache.
839 Implement ZOOM_resultset_sort which sorts a result set.
841 Implement chunked HTTP transfer.
843 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
845 --- 2.0.12 2004/02/16
847 Added member 'schema' to bend_explain_rr structure so that backend
848 can specify explain record identifier. Defaults to Zeerex 2.0.
850 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
852 --- 2.0.11 2004/02/16
854 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
857 Added init command for yaz-client which sends "extra" init request.
859 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
860 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
862 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
864 Make ZOOM error code for "invalid query".
866 Fixed compilation for SSL which wasn't properly enabled for all platforms.
868 --- 2.0.10 2004/02/05
870 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
873 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
875 Added option -p <file> to make Generic Frontend Server to write PID file.
877 Added option -D to put Generic Frontend Server in background on its own.
879 Make ZOOM C recognize option "password". If unset, "pass" is used
880 (for backwards compatibility).
882 Fixed a bug in Generic Frontend Server that could make it crash if a
883 client sets characterSetNegotation bit, but didn't pass negotiation stuff
886 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
887 Must be issued before open, in order to be in effect.
889 --- 2.0.9-6 2004/01/12 Debian/Windows
891 Make the SRU server more picky WRT unknown params, etc.
893 Bug fix: ZOOM scan response didn't return displayTerm - when present.
895 New YAZ client command, options, that sets Z39.50 options.
897 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
898 options from a string of tokens (one token for each option bit).
900 Update SRW diagnostic code messages.
902 --- 2.0.9-5 2004/01/07 Debian/Windows
904 Handle user defined stylesheet for SRW/SRU.
906 --- 2.0.9-4 2004/01/06 Debian/Windows
908 Fix bug in decoding of Content-Length.
910 --- 2.0.9-3 2004/01/06 Debian/Windows
912 Fix a bug with decoding of XML packed records.
914 --- 2.0.9-2 2004/01/05 Debian only
916 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
918 Fix bug in SRW/SRU diagnostics decoding.
922 Fixed bug in Generic Frontend Server which could drop records exceeding
923 preferred message size. Reported and fixed by Irina Dijour.
925 Fixed calculation of package size for structured records in Generic
926 Frontend Server. Reported and fixed by Irina Dijour.
928 Fixed namespace for SRW/SRU diagnostics.
930 Fixed SEGV in yaz-client that occured for HTTP connection errors.
934 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
935 this version is incompatible with version 1.0 and older YAZ SRW/SRU
938 CQL changes to reflect recent changes to the specification:
939 * Documentation talks about context sets instead of index sets.
940 * Documentation talks about indexes instead of qualifiers.
941 * The CQL-to-PQF transformer's configuration file now uses
942 "index.set.name = <attributes>" instead of the old form
943 "qualifier.set.name = <attributes>". (Both forms are still
944 understood but the latter is deprecated.)
945 * CQL terms with no explicit index specified are now interpreted as
946 cql.serverChoice instead of srw.serverChoice (which of course
947 behaves exactly the same.)
951 MARC conversion can now generate ISO2709 output in another
952 character set. yaz-marcdump uses this facility if you invoke it
955 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
956 functions from there can be used from C++.
960 Frontend server now transfers memory from decoded packages to stream
963 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
964 references to show up.
966 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
967 the ZOOM Abstract API. The older names for the same options are still
968 also supported for the benefit of old applications.
970 ZOOM-C supports "implementationId" and "implementationVersion" options
971 to go along with "implementationName". These allow the user code to
972 specify identification strings to be sent to servers.
973 Add OID for the new ExtLite attribute set.
975 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
976 as requested/supplid by Ere Maijala <ere@atp.fi>
978 For generic frontend server, reverse the order of
979 "toolkit-supplied / application-supplied" strings sent as implementationId,
980 Name and Version. Also, remove the spaces around the slash. This brings
981 the GFS in line with the behaviour of ZOOM-C on the client side.
983 Add function ZOOM_scanset_display_term.
985 yaz-client shows scan displayTerm if present.
987 Utility yaz-iconv is now installed by default along with the man page
990 Extend configure check for OpenSSL to use pkg-config where available (such
993 Incorporate patch by Morten Bogeskov which allows a Unix file socket
994 server to specify uid/gid/mask for socket using the format
995 unix:[user=uid,][group=gid,][umask=mask,]file=path
996 If file= is omitted the existing format is assumed, e.g.
998 in which case the mask is 0666 (rw for everybody).
1000 Major restructure of YAZ source. All source in libyaz is in src directory.
1001 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1002 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1004 Added man page for utility yaz-marcdump (used to be called marcdump).
1005 yaz-marcdump is installed by 'make install'.
1007 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1008 of incoming package failed.
1010 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1012 Change prototype of odr_perror: add const to message string.
1014 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1016 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1017 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1018 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1019 DNS lookup. There should not be any compatibility problems with this
1020 assuming that blocking=1 or 0 is used.
1022 Fix bad reference in UNIX comstack in function cs_addrstr.
1024 Fix for compilation on AIX.
1026 The generic front-end server (server/seshigh.c) now supports returning
1027 Init diagnostics to the client in User-information-field, in
1028 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1031 --- 2.0.4 2003/09/04
1033 Allow any CQL relation (not just all,any,exact,scr).
1035 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1036 that features the same UI.
1038 Implemented command update0 in YAZ client which is equivalent to
1039 update but uses old of Ext Update ASN.1.
1041 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1042 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1043 Previously no OID was used for this info.
1045 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1046 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1047 returns 'malformed search term' otherwise.
1049 SortResponse member resultCount now set to NULL in sort handler of
1052 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1055 Add three new utility functions for translating OIDs between various
1056 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1057 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1058 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1059 char *oid_to_dotstring(const int *oid, char *oidbuf);
1060 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1062 Reverted modifications for ES Update definition for z_IU0Update
1063 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1064 is back to YAZ 2.0.2.
1066 String value attributes for CCL parser.
1068 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1069 which their FirstSearch server returns in Init responses, sometimes
1070 carrying useful diagnostic information when Init fails. This has the
1071 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1072 "z39.50/oclcui.asn", where its definition is somewhat different from
1073 what OCLC document on their web-site, as required to interoperate with
1076 Support for anonymous authentication in yaz-client. Use the command
1079 * Fix the OID of the Index Data-local "admin" Extended Service from
1080 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1081 the 1000, which indicates a locally-defined OID, was a mistake.
1083 --- 2.0.3 2003/06/20
1085 Fix CCL directive @case handling so that it affects string match for
1086 both CCL keywords and qualifiers.
1088 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1089 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1090 Decoder has been updated with ASN.1 changes as listed in
1091 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1092 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1093 z_IUUpdate, remains unchanged.
1095 ZOOM_record_get may now return a record in a specific character set.
1096 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1097 "from" is the character set of record as returned by target. "to" is
1098 the character set to be returned. If omitted, "to" is UTF-8.
1100 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1102 New ODR utility, odr_getelement, which returns name of element for
1103 which encoding/decoding failed.
1105 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1106 in cases where a required element was omitted.
1108 Bug fix: some MARC8 sequences were not converted.
1110 New ZOOM option "step" which specifies number of records to be
1111 retrieved in one chunk. Used in conjunction with "start" and "count".
1113 SRW support for yaz-client. Use scheme http: to use it, e.g.
1116 yaz-client no longer does (un)intelligent character set conversions
1117 by default. Can be enabled with charset and marc_charset commands.
1119 xmalloc trace fix for 64-bit systems such as DEC alpha.
1121 Solaris 2.6 compile fix.
1123 New function, cql_strerror() translates SRW error codes, as returned
1124 by cql_transform_error(), into human-readable English strings. Used
1125 in yaz-client diagnostics when appropriate.
1127 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1128 converts it into a type-1 query which is sent to the server. This
1129 makes CQL available for use with all Z-servers, as opposed to the tiny
1130 minority that can handle CQL queries themselves.
1132 --- 2.0.2 2003/04/28
1134 New Debian package layout similar to the Redhat Package layout.
1136 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1137 and search result respectively.
1139 --- 2.0.1 2003/04/25
1141 Redhat package is now several packages: libyaz (runtime libraries),
1142 libyaz-devel (development and documentation, and yaz (utility programs).
1143 Package spec file by Morten Bøgeskov.
1145 New member 'schema' in struct bend_fetch_rr which the name of requested
1146 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1147 handler MAY set this to reflect the schema of the returned record.
1149 New member 'display_term' in struct scan_entry. GFS now sets member entries
1150 and allocates scan entries to be filled by user scan handler. In previous
1151 version, entries member was allocated by the scan handler. That still works,
1152 but the GFS will ignore member display_term - assuming it was NOT set by
1153 the handler. The fact that the GFS now allocates the entries both allows
1154 for new members and makes a scan handler easier to write.
1156 Fix CQL lex buffer overflow.
1158 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1159 SRU default recordPacking is string.
1161 SRU protocol support for frontend server.
1163 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1165 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1167 Added scan for the ZOOM shell (zoomsh).
1171 * String Identifers for Schemas (Amendment 5).
1172 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1173 Old definition for schema
1174 Odr_oid *schema; /* OPT */
1179 Z_InternationalString *uri;
1180 #define Z_Schema_oid 1
1181 #define Z_Schema_uri 2
1184 * resultCount parameter to Sort Response (Amendment 1).
1185 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1187 Support for SRW 1.0 over HTTP. This is an optional feature and
1188 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1191 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1192 on the same port. SRW SearchRetrieveRequests are mapped
1193 to bend_init,bend_search,bend_fetch,bend_close.
1195 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1197 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1198 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1200 ZOOM connections are SRW based if schem http is used for hostname
1201 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1202 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1204 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1205 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1206 distance=n, order=true/false, relation=le, prox unit=word. If
1207 n is omitted, distance 1 is used.
1209 Fixed problem with C compiler include path in wrong order.
1211 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1212 on Solaris. Patch from Ko van der Sloot.
1214 New MARC decode API. All new functions operate on a yaz_marc_t
1215 handle. The most important new functions are: yaz_marc_create,
1216 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1217 decode and destroy respectively. Decoder can produce formats
1218 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1219 include/yaz/marcdisp.h.
1221 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1222 to UTF-8, UCS-32, wchar_t or Latin-1.
1224 * Prototypes for yaz_iconv_-functions moved to separate header
1225 include/yaz/yaz-iconv.h.
1227 Make a few private functions 'static' in unix.c. This prevents
1228 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1230 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1231 are set when Init Response is received.
1233 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1234 but returns diagnostic set as well.
1236 New function yaz_strerror which is a portable wrapper for
1237 strerror/strerror_r/GetLastMessage.
1239 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1240 is returned for MARC. If type is "oai", then OAI MARC is returned.
1242 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1245 --- 1.9.2 2002/11/26
1247 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1249 Fix bad race conditions on SIGTERM and terminate gracefully in
1252 Move retrieval (data1) module to Zebra since nobody seems to be
1255 Add GRS-1 render for ZOOM using same format as yaz-client.
1257 --- 1.9.1 2002/10/05
1259 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1261 Fix broken ESpec handling in data1 module.
1263 SGML reader parses comments and makes them part of the data1 tree.
1265 Added several type casts so that YAZ compiles as C++ code.
1267 ZOOM didn't handle PDU encoding failures properly.
1269 Added more Bib-1 diagnostics (approved extensions).
1271 GNU configure: better check for iconv.
1273 More portable use of accept, getpeername. Check for socklen_t. Use
1274 int/size_t if socklen_t is not defined.
1278 PQF parser rejects bad queries - including those with extra
1279 characters in them. PQF parser used to silently ignore that.
1280 Cleaner API for PQF added, which allows you to get detailed
1281 error information for bad queries (see yaz/pquery.h).
1283 Fixed bug in ZOOM_record_get for type "database".
1285 Implemented mini iconv library supporting conversions between
1286 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1288 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1290 --- 1.8.9 2002/08/20
1292 Fixed ZOOM C record cache so that preferredRecordSyntax and
1293 elementSetName is used to check for already fetched records.
1295 --- 1.8.8 2002/08/02
1297 Added three members in bend_initrequest structure to facilitate
1298 character set negotiation.
1300 Fixed a bug in frontend server that could cause indefinite
1301 loops under rare conditions.
1303 Revised character set utilities (charneg.h) so that encoding
1304 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1306 For PQF, directive @term <type> sets term type for Scan/Search.
1307 Here <type> is general, string, numeric, null. The term type
1308 is inherited - just like @attr.
1310 New call odr_set_charset that sets character set conversion for
1311 international-strings on a ODR stream. Prototype is:
1312 int odr_set_charset(ODR o, const char *to, const char *from);
1313 The InternationalString is still represented as C string in YAZ
1314 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1315 won't). On the protocol level, you can use any encoding.
1317 Support for UNIX sockets in ZOOM.
1319 Solaris recv sometimes returns errno == ENOENT. It is treated as
1320 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1322 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1323 both client and server. Code by Morten Bøgeskov.
1325 --- 1.8.7 2002/05/22
1327 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1328 that they can be used directly from Visual Basic. You must recompile
1329 your windows APP if you're using ZOOM.
1331 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1332 Commands "lang" and "charset" sets language and character set respectively.
1333 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1334 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1336 Attributes from multiple CCL fields may be OR'ed rather than merged
1337 using directive "@field or". Fields are still merged by default -
1338 equivalent to "@field merge".
1340 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1343 Fixed bug in zget for parameter ExtendedServicesResponse.
1347 --- 1.8.6 2002/03/25
1349 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1351 Client displays USR.1:SearchResult-1 (hits per term).
1353 Additional Search Info for search in Generic Frontend Server.
1355 Fixed CCL parsing of "field=s".
1357 WIN32 installer - using the excellent NSIS software from nullsoft.
1359 Fixed CCL parsing of "field = - <number>".
1361 Added function yaz_marc_decode that decodes MARC for line mode
1362 display or XML (similar to that used by JZKit).
1364 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1365 Z39.50. But ISO/ILL was, however.
1367 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1368 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1371 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1373 --- 1.8.5 2002/02/03
1375 New YAZ client features: Command completion and new commands:
1376 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1377 Code provided by Jacob Poulsen.
1379 New call oid_trav, that visits all registered OIDs via callback.
1381 Function ZOOM_record_get now returns const char pointer rather than
1382 void pointer. It saves a lot of type casts.
1384 For YAZ client, command "auth" now allows you to set authentication
1385 in IdPass style. It is enabled when three tokens are given - order
1386 is user, group and password.
1388 Fix memory leaks in MARC record handling for ZOOM.
1390 New option for YAZ client, -k <kilobytes> that sets
1391 maximum record size. Similar to -k option for generic frontend
1392 server and yaz-ztest.
1394 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1396 Prefix query parser reports "fail" when bad attribute set is given.
1398 Fix in MARC decoder. Proximity logging. Fix for attribute set
1399 in scan handler for server. Patches by Shigeru Ishida.
1401 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1404 Configure option --with-openssl=<dir> now works when a directory is
1405 specified. Patch provided by Morten Bøgeskov.
1407 New option for YAZ client, -u <auth>, that sets authentication.
1409 ZOOM fix: error information was sometimes "missing", since error
1410 was cleared/reset too when it shouldn't.
1412 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1414 --- 1.8.4 2002/01/04
1416 Scan for ZOOM API. New object ZOOM_scanset. New functions
1417 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1418 ZOOM_scanset_destroy.
1420 New ZOOM function, ZOOM_connection_last_event, that returns type
1421 of last event (such as "receive data", "send data", "apdu received",
1424 New ZOOM option, schema, that specifies schema for retrieval.
1426 New CCL feature. Qualifiers can be aliases for one or more
1427 other qualifiers (if more than one is given, OR is used).
1429 ZOOM uses named result sets if target supports it.
1431 Two new YAZ client commands: . (dot, which sources a script of YAZ
1432 client commands), and ! (to execute shell command.). Implemented
1435 Working on Debian packages.
1437 --- 1.8.3 2001/11/19
1439 YAZ client enables named result sets only if target supports it.
1441 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1443 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1444 with key="host" to get same result.
1446 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1447 Function Z3950_resultset_record(s) returns references to records
1448 "owned" by resultset. To become owner use Z3950_record_clone.
1450 Function z_ext_record handles Extended Services. Thanks to
1453 --- 1.8.2 2001/11/12
1455 CCL Parser fix: ignore token comma when dealing with and-lists.
1457 Documentation updates for COMSTACK.
1459 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1460 Changed prototype Z3950_records. For some functions, int parameters
1461 were changed to size_t.
1463 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1466 New MARC decode/display function, marc_display_exl, which properly rejects
1467 non-ISO2709 records. YAZ client uses it.
1469 --- 1.8.1 2001/10/29
1471 Fix bug: local attribute set wasn't set correctly in PQF strings.
1475 * Old Z39.50 codecs no longer supported.
1477 Added ZOOM C binding. See http://zoom.z3950.org/
1479 Renamed states for COMSTACKs to avoid confusion with events.
1481 Implemented cs_look and proper cs_rcvconnect.
1483 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1485 Configure detects POSIX threads on OpenBSD.
1487 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1488 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1490 When error is returned from present handler, non-surrogate diagnostic
1491 is returned in present response (and fetch handler is no longer called).
1493 * Minor adjustments to pquery parser (PQF). Token characters may be
1494 escaped by using backslash (C-style).
1496 PQF parser allows string attribute values to be specified. For @attr,
1497 non-numeric characters after the equal-sign are treated as strings
1498 (e.g. @attr 9=title).
1500 CCL trunction character may be defined (@truncation in file)
1502 * function zget_ExtendedServicesRequest sets waitAction to
1503 waitIfPossible (was wait).
1505 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1508 CCL operator names may be set in field definition files (CCL_bibset).
1509 See ccl/bib1 for an example.
1511 Fixes in ASN.1 compiler for C++ compatibility.
1513 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1514 and "op_or" to avoid conflict with C++.
1516 Fixed problem with GNU readline detection on Redhat 7.0.
1518 Added step-size for Scan backend handler.
1520 Fixed bug that made the frontend server crash when no attribute
1521 set was specified for scan.
1523 Front-end server automatically switches to original working directory
1524 when installed as an NT service. Previously -w had to be specified to
1527 Added extended attributes for retrieval module (data1), so that data1
1528 records carry d1_readXML/SGML attributes. d1_read also supports
1529 null-data rules ( <tag/>)
1531 On UNIX when POSIX threads are available, a separate library libyazthread
1532 is created. Programmers should link with that library and the yaz library
1533 when using threads. The reason for the split was that some applications
1534 on Linux, such as Apache, doesn't work well when using shared objects that
1537 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1538 (or any frontend server) in SSL mode by specifying ssl: followed by
1539 address. Only tested on UNIX.
1541 Added feature for CCL module. Virtual structure s=al or s=ol generates
1542 and-list and or-list respectively instead of phrase search.
1546 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1547 log_mask_str. This was done to avoid name conflicts with other libraries
1548 (such as other PHP extensions).
1550 Added raw OID member for preferred record syntax (request_format_raw)
1551 and returned record syntax (output_format_raw) for backend fetch method.
1553 Config file yaz-config now accepts options so that it returns specific
1554 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1556 Shared library support for UNIX using GNU libtool.
1558 * Modified backend interface. Request/Response struct's replaced by
1559 one read/write C struct. For example bend_fetchrequest and
1560 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1561 Every handler - even search has to be registered in bend_init
1562 handler. This means that the YAZ library no longer refers to
1563 external functions and it makes it possible to make the whole
1564 thing a single DLL/SO.
1566 Added Segment handler for backend server.
1568 Added Zmbol/Zebra administrative functions to YAZ client.
1570 Threaded frontend server on UNIX (when POSIX Threads are available).
1571 Starting the server with option -T enables multi-threading.
1575 Added configure option --enable-comp/disable-comp to control use
1576 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1577 located in sub directory asn.
1579 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1580 in ${exec_prefix}/bin along with the other programs yaz-client and
1583 GNU automake used to maintain makefiles.
1585 Added several OID's.
1587 Changed retrieval module so that we can load records with no abstract
1588 syntax defined. Tagpaths in these records are fully composed of string
1591 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1595 On UNIX, the generated makefile now supports a proper 'make install'.
1596 The prefix can be set via GNU configure to set the install location
1597 (default is /usr/local).
1599 * YAZ programs client and ztest were renamed to yaz-client and
1600 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1601 locations, such as /usr/bin,/usr/local/bin,etc.
1603 * YAZ Header files were moved from include to include/yaz. YAZ Header
1604 files are referred to as include <yaz/log.h> rather than <log.h>.
1605 The YAZ include path (-I ..) is therefore the same as before. Programmers
1606 should update their #include statements or use -Ipath/include/yaz
1607 instead. The main motivation for doing this change is that YAZ header files
1608 can be installed in "standard" locations /usr/include,/usr/local/include
1609 without introducing conflicts, since ALL YAZ header files are stored
1610 in subdirectory yaz (under /usr/include for example).
1612 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1613 rather than project/workspace files. We switched because project files
1614 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1617 Changed name of logging function, logf, to yaz_log, to prevent name
1618 clash with some math-log functions. The YAZ header log.h defines logf
1619 to yaz_log (#define) so there should be no incompatibilities by this
1622 Added bend_start/bend_stop handlers for server. These handler are
1623 called on start/stop of server. For windows they are called whenever
1624 a service is started/stopped.
1626 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1627 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1628 in util/yc.tcl. The auto-generated C code structures are, in a few
1629 cases, incompatible with the old decoders. There are differences in the
1630 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1631 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1632 The preprocessor variable ASN_COMPILED is defined when the compiled
1633 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1634 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1635 wish to use the old encoders/decoders you can specify --disable-yc
1638 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1639 version so that it supports both new - and old version of DB Update
1641 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1642 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1643 change. The name parameter can be set to 0 in which no name is specified
1644 for the construction. The macros odr_implicit and odr_explicit sets name
1645 parameter to zero for the construction involved. New macros
1646 odr_implicit_tag and odr_explicit_tag are similar to the others,
1647 except that a name parameter is added. For programmers' that don't use
1648 ODR they probably only need to change the call to z_APDU and z_External.
1650 Added access control facility by interfacing the TCP wrapper library.
1651 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1652 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1653 name of the daemon and enables the access control as specified in
1654 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1656 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1657 den Dool <H.M.vdnDool@kub.nl>.
1659 Added reference ID parameter to most functions in server API - refer
1660 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1662 Changed name of ccl library to libccl.a (was ccl.a).
1664 Fixed bug in decoder for Explain (Category TargetInfo).
1666 Added support for GNU readline in client. Thanks to Jacob Poulsen
1667 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1669 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1670 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1671 IMPLEMENTATION! This change was made to the development version before
1672 the ZIG decided to retract the amendment. If any users MUST be
1673 compatible with the original Update definition, PLEASE CONTACT US, and
1674 we will include a separate definition corresponding to the old Update
1675 ES. Note that because of the change to the ASN.1 of the
1676 TaskPackageRecordStructure we cannot define a single structure that
1677 will support both versions.
1679 * Added const modifier to buffer parameter for some ODR/BER encoding
1680 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1681 completeWAIS, odr_dumpBER.
1683 Fixed bug in client.c which caused a crash when a scanResponse didn't
1684 contain positionOfTerm.
1686 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1687 * will cause an error in a client if a non-YAZ target sends both a
1688 * list of Scan entries and non-surrogate diagnostics.
1690 Retrieval module enhancements. Tag sets may be typed in the reference
1691 to it. From the .abs-file the "tagset" directive takes a third optional
1692 integer type for the tag set referenced. From a .tag-file the "include"
1693 directive takes a third optional type as well. The old "type" directive
1694 in the tag set itself is still recognized but acts as the default type
1697 Backend interface change. Individual Scan terms returned from bend_scan
1698 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1699 in include/backend.h.
1701 Retrieval module enhancements. Multiple tag sets and attribute sets may
1702 be specified in abstract syntax specs. Revised the error/warning for
1703 logging messages reported by the retrieval module when reading the
1706 Object Identifier system (oid_..) changed. The API is backwards
1707 compatible but the oid-routines now allocates new OID's when needed.
1708 Raw OID's may be specified in oid_getvalbyname.
1710 YAZ now uses GNU configure to generate Makefile(s).
1712 * Minor changes in some of the member names of DeleteResultSetRequest and
1713 DeleteResultSetResponse. See include/proto.h.
1715 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1716 and added member 'languages' in TargetInfo (which was missing).
1718 Changed the way attribute sets are handled in the retrieval
1719 module. These are now cached, just like the abstract syntaxes
1722 Changed YAZ so that it links with compiled ASN.1.
1724 Added Explain-schema definitions and mapping routines. The following
1725 Explain categories have been implemented: AttributeDetails,
1726 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1728 Fixed minor bug in Windows version of Server Library.
1730 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1732 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1734 Added EXTERNAL: UNIverse Resource Report (non-standard).
1736 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1737 ENUMERATED and SET OF.
1739 * Added 'const' to some of the char pointer arguments for the
1740 functions, data1_read_node, data1_getelementbytagname,
1741 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1744 Fixed bug in data1_insert_taggeddata - the last_child member of
1745 parent wasn't initialised.
1747 * Changed data1_read_record and data1_read_node so that the supplied
1748 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1749 doesn't refer to any parts of the "SGML"-buffer.
1751 Fixed bug in server library (Windows version of statserv_remove).
1753 * Changed code so that it compiles as C++. The type definition
1754 of Odr_fun which is a member of Odr_arm was changed. The result is,
1755 that an explicit typecast is needed for the fun pointer when
1756 using Odr_arm - as in:
1757 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1759 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1761 Implemented the new structured date and time definition as approved
1762 by the ZIG. Added schemaId element to the specificTag in Espec-1
1763 (also approved at the last ZIG). Thanks to RVDM.
1765 Added some Object identifiers (RVDM).
1767 Changed the Update Extended Service (RVDM).
1769 Added command "refid" to client which specifies referenceId for
1770 the following requests.
1772 Implemented extended service handling for server. See ztest.c
1773 for an example as well as backend.h. New handlers are registerd
1774 in the Init handler.
1776 * Changed interface for sort in server.
1778 Added new members to statserv_options_block. It allows a server
1779 to read options from another source than just the command line. Thanks
1780 to Charles Woodfield.
1782 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1783 renamed to zboolean. Some C++ compilers complained about the name.
1785 Minor changes to gils.abs. Added index 's' (sort) on title
1786 and date/time-last-modified.
1788 --- 1.4pl2 1998/1/30
1790 Fixed bug in server library regarding inetd mode (-i). This bug
1791 was introduced by release 1.4.
1793 --- 1.4pl1 1998/1/29
1795 Added sort facility in client and backend server interface.
1797 Fixed problem with dependencies in Makefile(s).
1799 Fixed bugs for encoders/decoders of extended services and
1802 Implemented sub-tree feature for schemas. Sub-trees are
1803 referenced in *.abs-files. See explain.abs for an example
1804 of the use of this feature.
1806 Modified bib1.att; local attributes for ANY didn't include
1807 ANY itself (only affects use of the retrieval module).
1809 Fixed bug in plain SGML reader in function data1_read_node:
1810 tags with prefix "var" was incorrectly interpreted as variants.
1812 Added feature "sub-schemas" to enable references to - and definitions
1813 of - group of elements.
1815 * Removed member parent from type data1_element (in data1.h).
1817 Implemented function odr_nullval() that returns the value of
1820 * Removed member num_children from data1_node (in data1.h).
1822 Made NT service interface part of the server library. The
1823 function statserv_main uses the NT service when required and
1824 calls the statserv_start / statserv_close routines.
1826 Routine zget_SearchRequest and zget_PresentRequest fills
1827 resultSetName/Id member with "default" instead of "Default".
1829 Fixed memory leak in server. Request queue member wasn't freed.
1831 Fixed nmem_exit so that memory is freed.
1835 Revised the CCL parser utility to be thread safe.
1837 Added function, oid_ent_to_oid, to replace the function
1838 oid_getoidbyent, which is not thread safe.
1840 * Added nmem_init and nmem_exit to initialize and release
1841 NMEM resources. Function nmem_init should be called once in the
1842 initial thread before NMEM/ODR is used. statserv.c and client.c
1843 have been changed accordingly. The change was necessary to make
1844 NMEM thread safe. The NMEM memory pool is shared amongst threads
1845 in a process. Unix-based applications will still work fine without
1848 Added NT Services interface for the the Z39.50 (statserv) Server.
1849 Refer to the ztest.c source on the usage.
1851 Windows 95/NT port using MSVC5.0. Project files are included in the
1854 * Defined new 'global' handle for the retrieval (data1) system. The
1855 new handled, data1_handle, describes the state of the data1 system.
1856 This handle is passed as first argument to virtually all
1857 data1 related routines. The functions data1_create and data1_destroy
1858 creates and destroys a data1 handle respectively.
1860 Added ODR encode stream member to all backend request structures
1861 init, search, scan etc. This stream should be used to allocate all
1862 memory used for the response when thread safe operation is needed.
1864 Changed the comstack utility, cs_addstr, to be thread safe. The
1865 returned hostname string returned by the function is now part the
1868 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1869 function. The cs_straddr takes a COMSTACK handle as argument, so this
1870 function must be used after cs_create and before bind/connect.
1871 This function is thread safe.
1873 Moved test server to 'ztest' directory - generic server code still
1874 in 'server' directory.
1876 Made prefix query (pquery.c) utility thread safe.
1878 Added new function modifier YAZ_EXPORT to 'export' public DLL
1879 functions when using windows (see include/yconfig.h).
1881 Added definitions to the OID database (util/oid.c) (RVDM).
1883 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1885 Added call to ccl_rpn_delete in client program.
1887 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1888 release of RPN structure.
1890 Added support for C++, headers uses extern "C" for public definitions.
1891 With input from RVDM.
1893 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1894 Thanks to Ronald van der Meer (RVDM).
1896 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1898 Added support for private extensions to the OID database
1899 (oid_setprivateoids()). Thanks to RVDM.
1901 Added optional, physical ANY (key replication)
1903 Fixed null-reference problem in GRS-1 output filter.
1905 Proximity operator added to Prefix Query Format (PQF).
1907 In test client command "base" accepts multiple databases.
1909 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1913 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1915 Smallish bug-fixes in the new encoders/decoders (explain).
1917 Bug fixed in DeleteRequest.
1919 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1921 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1923 Added SOIF syntax (using private OID for now) to retrieval module and client.
1925 Added Update extended service.
1927 Added SearchResult-1 additional info structure.
1929 Added optional CCL (ISO8777) interpreter as separate module. Available
1932 --- 1.2 1996/6/10 (1st anniversary release)
1934 Added Summary record syntax. Lightly tested.
1936 Added OPAC record syntax. Untested.
1938 Added ResourceReport service encoders/decoders. Untested.
1940 Fixed bug in z_Unit - wrong tagging on unitSystem.
1942 Fixed bug in the DiagRecs decoder.
1944 Added options for max PDU size and session timeout to frontend-server.
1946 Added documentation of query-language parsers and other supporting utilities.
1948 [frontend-server] Added Attribute set to the bend_scanrequest API.
1950 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1951 surrogate diagnostics were generated.
1953 [retrieval] Allow multiple local values for attribute.
1955 [retrieval] Allow multiple attributes per element in .abs files. index type.
1957 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1959 --- 1.1pl2 1996/4/10
1961 Minor changes, mostly specific to Zebra's requirements (retrieval)
1965 Repaired bug in frontend server when running multiple listening
1966 endpoints in dynamic mode.
1968 z_External() now won't break if a known, ASN.1 value comes encapsulated
1969 in an octet-string. The value will pass through unmodified in an Odr_oct.
1971 Added a bit of code to the demo client to decode & display
1972 ASN.1-structured records represented in the octet-aligned branch of
1973 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1975 Added z_ext_getentbyref() to the ASN module. Doc updated.
1977 * Completed the SCAN definition in the ASN module. This may break SCAN
1978 code based on older YAZ-versions at compile-time. The fix is easy -
1981 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1982 under the SCAN definition. Remember to initialize this, server-people.
1984 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1985 that this does not extend to ODR and ASN.
1987 Comstack allows insertion of established socket (primarily for
1988 inetd-operation of servers). Doc updated.
1990 Front-end server can now start from the inetd in TCP mode. Doc
1993 --- 1.0pl4 1996/1/24
1997 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1998 the rank and record number.
2000 Adjustments to the frontend server.
2002 Fixed diagnostic BER dumper. It ignored the file argument.
2006 Various changes to retrieval module.
2008 Changed the union discriminators of the protocol files from enums to
2009 ints paired with #defines.
2011 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2014 *Changed operator in the RPN structure to 'roperator', again to avoid a
2017 Fixed problems in Explain decoders/encoders.
2019 --- 1.0pl2 1995/12/6
2021 Memory bug in log module fixed.
2023 --- 1.0pl1 1995/12/5
2025 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2027 Bug in Explain DatabaseInfo module fixed.
2029 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2033 The shift to v1.0 signals that we now consider the *core* functionality
2034 of YAZ reasonably stable (the core being more or less equivalent to
2035 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2036 tested (Explain not at all - though that will happen soonish).
2038 Minor changes to code to support Windows port.
2040 Various minor changes after we're getting to use GRS-1 & co. more.
2042 Added Espec-1 format.
2044 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2045 of the protocol and it cannot be selected when encoding (maps into 'string'
2046 when decoding). Needed to talk to some servers.
2048 Demo client can request simple element set names.
2050 Added Diagnostic Format encoders/decoders.
2052 Added simple Close handling to frontend server (no hooks for resource
2053 reporting yet), and demonstration client.
2055 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2057 --- 1.0b3 1995/08/24
2059 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2060 handled incorrectly when records were requested in the searchResponse. This
2061 will only affect you if you use the frontend-server.
2063 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2064 Test-client will ask for and print GRS1. Ztest will return dummy records
2067 Added Explain encoders/decoders to the service-level API. Untested.
2069 Added Extended Services: Item Order encoders and decoders to the Service-
2070 level API. Untested. We could use a recent copy of the pertinent bits
2071 of the ILL protocol to add those bits.
2073 Added diagnostic format 1 encoders/decoders to the service-level API.
2076 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2077 odr_cons.c, which causes a more correct output.
2079 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2080 was always set to 0 when no records were requested in the searchRequest.
2082 * Added better external-handling. This shouldn't harm old code that
2083 *encodes* externals. It can break code that looks for a
2084 'single-ASN1-type' representation, since those types that are known
2085 are now decoded immediately. Look at the SUTRS sample code in
2086 seshigh.c and client.c. Documentation updated.
2088 Handling of structured records in bend_fetchresponse. Length -1 marks
2089 structured record, type is deduced from format field.
2091 --- 1.0b2 1995/06/27
2092 Fairly quick maintenance release to add SUTRS support.
2094 Fixed handling of SUTRS records in the demonstration client.
2096 * Added format field to the bend_fetchrequest and bend_fetchresponce
2097 structures of the backend API (frontend server). When the record is
2098 returned, the value of the format field is mapped to an OID. The
2099 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2100 of the record. The special value VAL_NONE in the bend_request means
2101 that no specific format was requested by the client. Documentation
2102 updated accordingly. Test server (ztest) will return a fixed dummy
2103 SUTRS record if your client requests SUTRS.
2105 Documentation updated accordingly.
2107 You can now set external libraries and RANLIB support in the top-level
2111 First public release.
