1 Better SRW-to-Bib-1 diagnostic mapping.
5 Added support for SRU scan for ZOOM.
7 Added support for the use of the older versions or Extended Service
8 Update in ZOOM. To faciliate this, an option "updateVersion" may be
9 set to the version , 1=first, 2=second, 3=third. The third version is
10 what ZOOM C has used so far. And that, obviously, is the default.
12 Added support for CCL queries in Z39.50 queries sent to the GFS (and
13 therefore in Zebra and in SimpleServer-based applications). The new
14 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
15 qualifier file used to transform incoming CCL queries into Type-1 RPN,
16 which is passed into the back-end search callback function.
18 Added support for HTTP Basic authentication in clients: the SRU/W
19 codec encodes the username/password elements of the PDU structure
20 appropriately, and these may be set using the "user" and "password"
21 options in ZOOM-C applications (the same options that are used for
22 Z39.50 authentication).
26 Fixed bug #1208: SSL appears to be broken in ZOOM.
28 Fixed bug #1206: Libxml2 include path weirdness.
30 Added oid_name_to_dotstring.
32 Allow elementSetName to be specified for ZOOM C record update.
34 Allow waitAction to be specified for ZOOM C based for Extended Services.
36 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
37 syntax OID. Bug introduced in YAZ 3 series.
39 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
43 Fixed bug #1157: yaz-client does not read .yazclientrc from current
44 directory. yaz-client now reads commands from file given by option -f
45 if specified; then tries to read .yazclientrc in current directory.
46 Failing that, it reads .yazclientrc from user's home directory.
48 Added support for correlationInfo Note and ID for Record Update via
51 Added yaz-client command querycharset which specifies character set for
52 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
53 (termListAndStartPoint).
55 Charset ISO5428:1984 is an alias for ISO5428-1984.
57 Implemented a way to perform scan in a result set using Z39.50. This
58 is achieved by attaching the result set name in the characterInfo
59 (type InternationalString) of OtherInformation in the Scan Request PDU.
60 The result set is identified in the otherinformation by the new OID:
61 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
62 This allows for scan in result set and faceted search . Zebra did some
63 of this in the APT term using attribute type 8 and value being result
64 set. Using the OtherInformation approach for this is cleaner and easier
65 to work with in proxies and the like. This facility can be used in
66 yaz-client using new command setscan which takes a result set as first
67 argument, start position (APT) as second.
69 Changed decoding of SRU XML packed records to deal with servers that
70 have recordData with XML data with multiple root nodes. Also make
71 comparison for recordPacking case insensitive. Again, one server
72 returns "XML" where others return "xml".
74 For SRU responses allow Content-Type application/xml as well as text/xml.
78 Fixed bug in character set conversion of BER strings. Bug introduced
83 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
85 For OID class, use oid_class consistently.
87 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
90 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
91 character set for bibliographic information interchange". By Giannis Kosmas.
93 Added documentation on new OID API.
97 Changes to generic frontend server interface: added new member
98 'query_charset' for bend_initrequest structure. A backend init handler
99 should set this member to its native character set for query terms.
100 When defined, the frontend server logic will announce this character set
101 to a client if the negotiationModel bit is set by the client. All server
102 implementors are encouraged to specify this. If a backend server does not
103 specify this a warning is issued using yaz_log(YLOG_WARN,..).
105 Added CCL utility to remove terms (stop words) from resulting RPN
106 tree. This is handled by functions with prefix ccl_stop_words_ .
108 New ZOOM C option, "rpnCharset", which allows client-side conversion of
109 terms in RPN queries.
111 Clean-up the CCL API. Moved some internal structures from ccl.h to
112 private header cclp.h. Changed ccl_parser_create so that a Bibset must
113 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
114 This is replaced by ccl_parser_find_str which takes a string instead.
116 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
117 libyaz.la is the core of YAZ except the generic frontend server and
118 does not depend on POSIX threads anymore. libyaz_server.la is the
119 generic frontend server facilities and uses POSIX thread functionality
120 if available. The libyaz.la no longer depends on POSIX threads because
121 the number of global structures is limited. NMEM no longer re-uses blocks
122 between threads ; it simply free's memory immediately but allocates in
123 "large" chunks as usual. We don't expect any performance penalties
124 because of this. The yaz_log system is still using a global log_level so
125 caution must be taken when modifying it with yaz_log_init_.. +
126 yaz_log_mask_str. This, however, should not cause any trouble because
127 these functions are called during initialization of application code
128 anyway. `yaz-config --libs server` returns libs for server applications;
129 `yaz-config --libs` returns libs for non-server applications.
131 New OID database - with public definitions in oid_db.h. Removed old OID
132 database including the head oid.h and definitions such as enum oid_value
133 and struct oident. The new OID database uses the same string names as
134 before but the 'protocol' is gone. There are now only two representations
135 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
136 converts from string to OID; functions with prefix yaz_oid_to_string
137 converts the other way.
139 Change to emit_term() in CQL-to-PQF query translation: when a term has
140 the /regexp relation modifier, do not process it for leading and
141 trailing "^" and "*", which have quite different meanings in regular
144 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
145 write handlers no longer carries a 'last' parameter. This will make
146 yaz_iconv flush "less" characters. A flush is performed by call to
147 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
149 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
150 removed, because function yaz_query_to_wrbuf does the same.
152 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
153 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
155 Deprecated MARC utility functions removed.
157 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
160 Branch split: YAZ_2_1_55_branch
162 --- 2.1.54 2007/03/16
164 Fix to ZOOM-C so that transparent reconnection is properly handled on
165 connections that are in asynchronous mode.
167 Fixed compilation on OpenBSD 4.0.
169 Large strings in GRS-1 records are now properly displayed in yaz-client.
171 Added character conversion support for "advancegreek"; based on patch from
174 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
175 sequence is met. Before the error was not set so it would be unknown.
177 Adjust yaz-marcdump MARC reader so that it skips until record separator
180 --- 2.1.52 2007/03/07
182 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
183 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
184 fd_set structure used as a bitmask for the FDs to be selected on.
186 Using ACX_PTHREAD macro to check for POSIX threads.
188 Fixed have-vsnprintf check.
190 --- 2.1.50 2007/02/23
192 Fixes for configure on BSD. Bug #900.
194 Added snprintf/vsnprintf wrappers for systems that don't have
195 limits (heavens forbid).
197 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
198 created before all previous tasks were completed and removed from the
199 task queue, the new task could be removed by a mistake.
201 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
203 Implemented pass-through CQL-to-PQF conversions. Bug #861.
205 Fixed bug #832: Problem with MARC/charset in yaz-client.
207 Fixed bug #668: save command line history for yaz-client.
209 Fixed bug #830: pkg-config support.
211 --- 2.1.48 2007/01/23
213 Extended ZOOM result set options with two options that may be read by
214 a client: resultSetStatus and presentStatus with values as specified for
216 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
218 Fixed bug #827: Using SSL fails on Debian etch.
220 Fixed bug #826: Weird looking chars for set of MARC records.
222 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
223 that is treated as an ItemOrder with itemRequest being an XML document
224 external. The value of "doc" is the content.
226 Extended the GFS search facility. New member of bend_search_rr
227 'estimated_hit_count' signals that hits is known to be an estmate
228 (higher or lower than real hit count). New member 'partial_resultset'
229 signals that the search was partial (hit count is lower or equal than
230 real hit count). For Z39.50, the information is stored in resultSetStatus
231 member of SearchResponse APDU. For SRU, the information is signalled
232 via SRU diagnostic 59: "Result set created with valid partial results
235 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
237 --- 2.1.46 2007/01/13
239 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
241 Added ZOOM_connection_peek_event.
243 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
244 the following new functions:
245 ZOOM_event_nonblock, ZOOM_connection_process,
246 ZOOM_connection_get_{socket,mask,timeout},
247 ZOOM_connection_fire_event_{timeout,socket}.
248 The existing blocking event handler, ZOOM_event, is a wrapper for the
249 + blocking ZOOM_event_sys_{poll,select}.
251 Implemented function ccl_xml_config which parses XML version of CCL
252 configuration (bug #798).
254 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
256 Added timings utility (yaz/timing.h)
258 --- 2.1.44 2007/01/03
260 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
263 Fixed bug #779: Rotation of apdu.log fails.
265 Fixed for character set conversions:
266 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
267 Honor G1 set in MARC-8 decoding.
269 --- 2.1.42 2006/12/17
271 Fixed bug #775: char conversion does not handle Alternative UTF-8
274 Implemented function yaz_marc_read_line which parses MARC line format
275 records. There is a wealth of formats out there. So far, this function
276 reads line records produced by yaz_marc_write_line.
278 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
279 more generic and easier to remember(!) options: -i format and -o format
280 which specifies input format and output format respectively - where
281 format is one of "marc", "marcxml", "line", "marcxchange".
283 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
284 does not print anything except warnings for records.
286 For yaz-marcdump, added support for MARC split into files (-s) with a given
289 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
290 spec, at http://www.loc.gov/standards/sru/record-update/
291 This has changed the binary layout of the following structs:
292 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
293 bend_update_rr . Patch by Ko van der Sloot.
295 Added GFS utility function bend_assoc_is_alive which returns 1 if
296 association is still alive (client is connected); 0 otherwise (client
297 closed connection). This allows busy servers to stop working for
300 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
301 been a separate piece of software. This version of ziffy has been modified
302 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
304 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
306 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
307 Client code may now interrogate options such as "init_opt_sort" to
308 find out whether the server claims to support various options.
310 --- 2.1.40 2006/11/27
312 Added utilities yaz_{set,get}_esn to set/get element set name from
315 Removed the build of libyazthread.la. The libyaz.so is the threaded version
316 of YAZ and has been so since YAZ 2.1.10.
318 Implemented ZOOM_record_error which returns error information for
319 record (surrogate diagnostic).
321 --- 2.1.38 2006/10/31
323 Updates for SRU Update by Ko van der Sloot:
324 1. Changed name from "operation" to "action"
325 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
326 versions in the code, marked as 'backward compatible'.
327 3. Added diagnostics for SRU Update.
329 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
331 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
333 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
335 For GFS, fixed problem with SRU diagnostic 'First record position out of
336 range' being issued for 0 hits.
338 zoomtst10 part of Windows Build.
340 --- 2.1.36 2006/10/13
342 Implemented yaz_filepath_comp which splits a path into file path
343 components (required by Zebra 2.0.3+).
345 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
346 BSD inspired license until now so this should not have any real impact on
347 anybody. See http://www.opensource.org/licenses/bsd-license.php
349 Fixed bug #687: Missing log lines.
351 Fixed bug #678: CQL to PQF translation does not preserve double-quote
354 Fixed bug #689: SRU diagnostics to be added.
356 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
357 whether a connection is idle (no more work do do).
359 --- 2.1.34 2006/10/04
361 Change type of optval from long to int for invocation of setsockopt with
362 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
364 Added support for specifying the max log file size for the Generic
365 Frontend Server. The size is given with option -r.
367 --- 2.1.32 2006/09/21
369 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
371 --- 2.1.30 2006/09/17
373 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
376 Fixed bug in Generic Frontend Server that could cause a server to stop
377 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
379 For the generic frontend server, the maximum record size is used as maximum
380 size of incoming packages (SRU + Z39.50). The value until was previously
381 only used in Z39.50 Init negotiation and, later, in a session controlled
382 sizes of records returned. This is controlled using -k option. It can be
383 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
385 --- 2.1.28 2006/09/04
387 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
390 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
392 New option for yaz-marcdump -lpos=value which allows setting a portion
393 of MARC header to a certain value.
395 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
397 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
398 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
400 --- 2.1.26 2006/08/15
402 Fixed problem with SRU mode type (soap, get, post) for yaz-client
405 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
407 --- 2.1.24 2006/08/08
409 Fixed MARC ISO2709 encoding routines to deal with character set
412 Minor changes to GFS logging. Database included in search request log
415 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
416 cached/multiple records.
418 Shared libraries are built by default on Unix+configure.
420 Changed cql2pqf transformation to use a different evaluation order. The
421 new order is: always, relation, structure, position, truncation, index
422 and relationModifier. Old order was: always, relation, relationModifier,
423 structure, index, position, truncation. Note that the the latter ones
424 override former ones for identical attributes.. The new scheme means that
425 it is possible to override any existing attribute with a relationModifier.
426 And also that it is possible to override everything for the index rule
427 (except the ones listed in relationModifier). No order is perfect but this
428 one, we believe, covers more real cases.. The "always" should have been
429 called "default", since the attributes there can be overridden with all
432 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
433 compilation phase, but also for yaz-config --cflags output. This allows
434 us to have public headers with Libxml2 stuff in them . It should also,
435 eventually, make Libxml2 checks redundant in packages using YAZ, such
438 --- 2.1.22 2006/06/15
440 Changed SRU update structure bend_update_rr so that SRU diagnostics are
441 stored in uri, message and details.. Previously diagnostics were stored
442 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
443 compatibility.. but he's probably the only one affected, so.
445 Added support for CCL, compiled on the client side, in ZOOM-C. This
446 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
447 input; the resulting query objects can be used for for searching with
448 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
450 YAZ' configure searches for OpenSSL by default.
452 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
453 SL_CTX_use_certificate_file. See
454 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
455 for more info. Thanks to Ko van der Sloot.
457 --- 2.1.20 2006/06/02
459 Bug #600: SRU GET, POST support for yaz-client. Introduced
460 command 'sru' which selects method SOAP/GET/POST.
462 Allow missingValueAction to be specified for the sortspec string -
463 function yaz_sort_spec. By default, the missing value action is null.
464 Use ! to specify "abort". Use = followed by stringvalue to specify default
467 Ensured that Present-handler (if defined) is called in GFS before any call to
468 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
469 searchRetrieve requests.
471 Documentation for YAZ is now based on the Docbook XML/XSLT using
472 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
473 is no longer depending on jade/openjade or docbook-to-man scripts.
474 PDF is no longer part of the distribution - but can optionally be
475 made using DSSSL/jadetex or FOP.
477 Added retrieval handling support in Generic Frontend Server to support
478 conversion between MARC/XML as well as XSLTtransforms. See
479 etc/yazgfs.xml for an example.
481 Added Authentication support to Generic Frontend Server in SRU
482 mode. Authentication using HTTP Basic is supported, as is the use
483 of 'x-username' and 'x-password' parameters in the request itself.
485 Added support for a new character set MARC8s identical to MARC8 except
486 that it converts combined characters to single Unicode characters in the
487 Latin-1 range (when possible).
489 --- 2.1.18 2006/04/24
491 ASN.1 compiler 0.4: generates brief Doxygen file header for
492 generated .h/.c files.
494 Utility yaz_iconv now supports conversion to MARC-8.
496 New facilities for the MARC module. The reading - and writing of
497 content are separate methods for the yaz_marc_t handle. The following
498 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
499 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
500 format). Write functions have prefix yaz_marc_write_.. The existing
501 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
502 available. Removed support for OAI-MARC and simplexml (not the
503 simplexml from PHP5).
505 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
506 to be returned for this connection.
508 --- 2.1.16 2006/03/31
510 Allow multiple languages and charsets to be specified with
511 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
512 negcharset iso-8859-1,utf-8
514 Translation of proximity nodes from CQL into PQF now works.
516 Moved to automake 1.8, 1.9.
518 Added function yaz_log_set_handler which allows a log handler to be
519 installed. This handler will be called for all log messages. Output
520 to file is also produced; but that can be disabled by passing NULL
521 fname to yaz_log_init_file.
523 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
525 For SRW (including GFS), accept application/soap+xml as content-type
528 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
529 produces NO stylesheet reference even if a default stylesheet is specified
532 --- 2.1.14 2006/03/14
534 Updated Windows package to include yazd.dll + yazd.lib for the
535 Development component.
537 If the environment variable YAZ_LOG is set, then it is used as a
538 string indicating the default level of logging to use if not
539 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
540 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
541 used as before. So, for example, to omit warnings from YAZ logging,
544 cql_transform() now map structure and other attributes before indexes,
545 so that index-specific structures and other attributes can override
546 defaults. So now a combination of mapping specifications such as:
548 index.dc.date = 1=date-modified 4=5
549 does the right thing.
551 cql_transform() now also respects the "always" mapping specification,
552 which establishes an initial set of attributes to be used for all
553 terms except where overridden by more specific attributes associated
554 with the index, relation or modifier.
556 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
557 which mode to use; one of "post", "get" or "soap" (SRW, default).
559 Fixes for yaz_iconv routines: changed trie-based character set conversions
560 to use only non-negative values for bit fields due to Sun's C compiler not
561 supporting negative values.
563 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
564 sequences where not read correctly. Fix by Rustam Usmanov.
566 Updated win/makefile to use options, settings which makes things
567 compile with VS C 2005.
569 --- 2.1.12 2006/02/01
571 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
573 In ZOOM socket code, use select instead of poll on MacOSX.
575 ZOOM-C now support client-side compilation of CQL into RPN that is
576 sent to the server, enabling CQL to be used against all Z39.50
577 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
578 ZOOM_query object, and submit it using ZOOM_connection_search().
579 The CQL-to-RPN translation uses a configuration file, the name of
580 which must be specified in the Connection's "cqlfile" option.
582 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
583 function, which takes as its start-term parameter a ZOOM_query object
584 (which may have had either CQL or RPN set into it).
587 --- 2.1.10 2005/11/29
589 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
590 GFS to support this as well. Backend handler, bend_srw_update, does the
591 update work. Code contributed by Ko van der Sloot.
593 Allow retrieval of Search Result-1 information in ZOOM by the use of
594 options that are attached to a result set. ZOOM documentation updated
597 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
598 UTF-8 conversion. Patch by Raj Patel.
600 Added option -m to GFS to control formatting of timestamps in log file.
602 Added 'exit' as synonym for 'quit' in yaz-client
604 Added support for specifying SRW resultSetId + resultSetIdleTime in a
605 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
606 for the new members. Patch by Ko van der Sloot.
608 Added support for SRU POST. It is supported for content-type
609 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
611 Do not build the separate Multi-threaded (MT) library libyazthread.la.
612 Instead make the library libyaz.la multi-threaded. Threading as a whole
613 can still be disabled by configure option --disable-threads. Previosly,
614 with older GLIBCs there were problems with MT libs under Apache. This
615 has now been fixed a long time ago.
617 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
620 CQL module modified to be case insensitive for relations/indexes/operations.
622 Fixed bug in CQL transform code: incorrect value relationModifieder
625 Added 'show all' command for yaz-client which retrieves all results
628 Added new yaz-client, xmles, which takes a (private) OID and
629 a document to be sent as an extended service request.
631 Describe new yaz-client commands wait_response and set_auto_wait.
633 Increase TCP/IP listener backlog from 3 (which I am guessing was
634 copied from the SunOS manual entry way back when) so SOMAXCONN, so
635 that the socket will queue as many incoming connections as it's able
636 to handle ongoing connections. In other words, it will never now
637 refuse a connection that it would be able to handle merely because
638 it's not got around to accepting() enough of the pending connections
639 yet. This is the behaviour anyway under Linux, where the listen()
640 argument is ignored; but not under BSD and on systems such as
641 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
642 YAZ-based servers should now be uniform across operating systems in
645 yaz-marcdump uses 64-bit file access on some systems. This is enabled
646 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
647 This allows yaz-marcdump to read large MARC batches (>2 GB).
649 Modified all YAZ source files - except the source which is auto-generated
650 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
653 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
654 corresponding to the existing *_setl() function. These allow option
655 values containing arbitrary valuues.
657 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
658 ZOOM_resultset_sort() in new applications. Its behaviour is identical
659 except that it returns an indicator of whether or not the sort
660 criterion was accepted (0 for OK, -1 for invalid).
664 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
665 MARC output rather than returning "new" buffer.
667 yaz-client warns about unknown init options.
669 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
673 Added support for SRW sort in Generic Frontend Server. Patch
674 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
675 sortKeys - or NULL if none is provided.
677 Fixed bug #307: It was impossible to specify indefinite/no timeout
678 for ZOOM_event. Special timeout value -1 now means indefinite timeout
681 Added support for multiple languages and charsets to be specified in
682 ZOOM. Each charset/language is separated by a blank. If negotiation is
683 in effect in init-response, Option
684 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
685 Code based on patch by Vasiliy Osadchuk.
687 Fixed bug #306: infinite recursion that occurred when calling
688 yaz_log_level_init as the first call (before other log level or
691 Fixed bug in scan handling in front end server: if preferred-Position-In-
692 Response was non-present, a NULL pointer referece was performed.
696 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
697 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
698 now defined for all those error codes. So instead of putting 109 in
699 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
700 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
702 Modified the yaz-marcdump utility to skip garbage bytes between MARC
705 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
707 Program yaz-client now exits and produces an error message if multiple
708 Z39.50 servers are specified on the command line (none or one allowed
711 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
716 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
718 Fixed bug #272: Preserve spacing for CCL terms.
722 Added support for virtual hosts and multiple backend servers for
723 the YAZ frontend server. The configution is XML based and
724 support specificition of CQL to RPN mappings and explain information.
725 See section "Virtual Hosts" in the YAZ manual.
727 Extended OPAC display utility. OPAC display utility renders
728 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
729 to supplement yaz_marc_decode_wrbuf.
731 Fixed a bug in MARC decoder that could caused it to crash for some
732 invalid MARC records. More diagnostics and warnings where added in
733 XML output (warnings, etc are stored in comments).
735 --- 2.0.34 2005/02/08
737 Fixes for UNIX domain sockets. Bug #261.
739 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
741 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
742 Added yaz_marc_subfield_str which defines subfield lead string which is
743 used in YAZ_MARC_LINE format. Default string is blank+$. Added
744 yaz_marc_endline_str which defines end of fields string used in
745 YAZ_MARC_LINE format. Default string is newline.
747 Experimental support for MarcXChange. This format can be produced
748 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
749 http://www.bs.dk/standards/MarcXchange.xsd
751 Added yaz-client commands scansize that sets maximum number of
752 entries to be returned by scan.
754 --- 2.0.32 2005/01/11
756 Added support for SRW scan in yaz-client and Generic Frontend Server.
758 * Added whereInList member to SRW Scan Term.
760 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
762 Fixed NMEM system to return aligned blocks on the smallest boundaries
763 that are suitably aligned for all possible types on the particular
764 architecture YAZ is being built for.
766 --- 2.0.30 2005/01/04
768 Fixed numerious warnings that was issued with newer versions of GCC.
770 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
771 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
774 Make YAZ Generic Frontend Server slightly faster.
776 Enhance (and reduce) logging for Generic Frontend Server.
778 Revert YAZ log system so that it flushes every write operation
779 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
781 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
782 instead of LOG_, due to name clash with syslog(3). LOG_ are still
783 present. New applications should define YAZ_USE_NEW_LOG=1 - this
784 will effectively disable old definitions.
786 --- 2.0.28 2004/11/09
788 Added yaz_log_time_format which specifies log format using
791 Added yaz_log_module_level which returns mask for a module. Value
792 is non-zero mask a if module is enabled; zero if disabled.
794 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
795 in include/yaz/cql.h.
797 Fixed bug #176: Dont throw diagnostics on empty SRU args.
799 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
801 Fixed bug #172: RPM builds does not enable SSL.
803 Doxyfile.in part of dist. Doxyfile generated by configure.
805 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
806 are given and the corresponding component does not exist.
808 Extend CCL documentation in YAZ reference. Describe r=r.
810 --- 2.0.26 2004/10/01
812 Fixed MARC->MARCXML conversion to properly deal with
813 fields, subfields, indicators having non-ASCII characters.
815 Fixed MARC->MARCXML conversion so that ASCII control characters
816 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
819 Added YAZ GFS support for conversion from Z39.50 surrogate
820 diagnostics to SRW surrogate diagnostics.
822 Bug fix: YAZ GFS did not return schema in explainResponse.
824 --- 2.0.25 2004/09/30
826 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
827 now converts recordSchema to elementSetName as well as schema URI.
829 Fixed bug in COMSTACK that prevented HTTP request packages from being
832 --- 2.0.24 2004/09/29
834 Added CCL facility r=r "range" which is similar to r=o "ordered" but
835 does not require white-space before and after the dash in a range, e.g.
836 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
839 Fixed a few AC_TRY_LINK configure tests that did not operate properly
840 due to new GCC removing "redundant" code.
842 Added yaz-client commands scanpos and scanstep that sets preferred
843 position and step-size for scan.
845 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
847 Added CCL utility ccl_qual_buf which parses one or more CCL
848 spec lines in a buffer.
850 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
851 of name and value - ignoring empty lines and comments.
853 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
855 Added odr_get_element_path which returns current element path for an
856 ODR handle. This utility is useful in error handling or user-defined
859 Added ODR_PRINT utility odr_set_stream which is is a more generic
860 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
861 to a write function and pointer to close function. The close function - if
862 non-NULL - will be called during odr_destroy.
864 Fixed bug in CCL parser where truncation char was not removed from
865 right side when truncation=both was in effect.
867 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
870 --- 2.0.23 2004/08/11
872 Fix buffer overrun in CQL parser when dealing with proximity (%).
874 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
875 to UTF-8/UCS conversion is now only based on codetables.xml.
877 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
879 --- 2.0.22 2004/08/06
881 Add support for more "commit changes" in ZOOM (uses Extended Services).
883 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
886 Yet another small fix for configure of SSL.
888 --- 2.0.21 2004/05/14
890 Fix SSL libs for configure when --with-openssl=DIR is given.
892 --- 2.0.20 2004/05/10
894 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
896 SSL comstack now uses yaz.pem certificate file on server side
897 by default. Certificate filename can be configured by calling
898 comstack function cs_set_ssl_certificate_file before cs_bind is used.
900 Fix bug regarding multiple calls to ZOOM_connection_connect.
902 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
904 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
905 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
907 ZOOM now allows inspection of X509 peer certificate for verification.
908 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
910 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
911 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
912 as "modular" but it simplifies things.
914 Added cs_get_peer_certificate to that returns peer X509 PEM.
916 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
917 NULL if SSL is unavailable.
919 Documentation about MARC decoding tools.
921 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
923 --- 2.0.19 2004/03/30
925 Rename CHANGELOG to NEWS to follow GNU style packing.
927 Fix bug with missing initialization of member in init_diagnostics.
928 This bug affects threaded version of GFS server.
930 --- 2.0.18 2004/03/20
932 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
935 Ensure zlib.dll is packed with Windows install.
937 --- 2.0.17 2004/03/17
939 Fix encoding of xsd:string to use text instead of CDATA.
941 Fix endless loop in CQL parser with unbalanced ".
943 Use a more compact way to store MARC-8 conversion tables.
945 --- 2.0.16 2004/03/16 Debian only
947 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
950 Update CQL parser to use new CQL 1.1 modifiers for booleans and
955 --- 2.0.15 2004/03/01
957 Another fix for decoding of XML packed records.
959 --- 2.0.14 2004/02/25
961 Fixes for Chunked encoding. White space not ignored after length spec.
963 Update NS and use default NS for SRW diagnostic elements.
965 --- 2.0.13 2004/02/23
967 Implement ZOOM_resultset_cache_reset which resets record cache.
969 Implement ZOOM_resultset_sort which sorts a result set.
971 Implement chunked HTTP transfer.
973 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
975 --- 2.0.12 2004/02/16
977 Added member 'schema' to bend_explain_rr structure so that backend
978 can specify explain record identifier. Defaults to Zeerex 2.0.
980 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
982 --- 2.0.11 2004/02/16
984 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
987 Added init command for yaz-client which sends "extra" init request.
989 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
990 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
992 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
994 Make ZOOM error code for "invalid query".
996 Fixed compilation for SSL which wasn't properly enabled for all platforms.
998 --- 2.0.10 2004/02/05
1000 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1003 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1005 Added option -p <file> to make Generic Frontend Server to write PID file.
1007 Added option -D to put Generic Frontend Server in background on its own.
1009 Make ZOOM C recognize option "password". If unset, "pass" is used
1010 (for backwards compatibility).
1012 Fixed a bug in Generic Frontend Server that could make it crash if a
1013 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1016 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1017 Must be issued before open, in order to be in effect.
1019 --- 2.0.9-6 2004/01/12 Debian/Windows
1021 Make the SRU server more picky WRT unknown params, etc.
1023 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1025 New YAZ client command, options, that sets Z39.50 options.
1027 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1028 options from a string of tokens (one token for each option bit).
1030 Update SRW diagnostic code messages.
1032 --- 2.0.9-5 2004/01/07 Debian/Windows
1034 Handle user defined stylesheet for SRW/SRU.
1036 --- 2.0.9-4 2004/01/06 Debian/Windows
1038 Fix bug in decoding of Content-Length.
1040 --- 2.0.9-3 2004/01/06 Debian/Windows
1042 Fix a bug with decoding of XML packed records.
1044 --- 2.0.9-2 2004/01/05 Debian only
1046 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1048 Fix bug in SRW/SRU diagnostics decoding.
1050 --- 2.0.9 2004/01/05
1052 Fixed bug in Generic Frontend Server which could drop records exceeding
1053 preferred message size. Reported and fixed by Irina Dijour.
1055 Fixed calculation of package size for structured records in Generic
1056 Frontend Server. Reported and fixed by Irina Dijour.
1058 Fixed namespace for SRW/SRU diagnostics.
1060 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1062 --- 2.0.8 2003/12/22
1064 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1065 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1068 CQL changes to reflect recent changes to the specification:
1069 * Documentation talks about context sets instead of index sets.
1070 * Documentation talks about indexes instead of qualifiers.
1071 * The CQL-to-PQF transformer's configuration file now uses
1072 "index.set.name = <attributes>" instead of the old form
1073 "qualifier.set.name = <attributes>". (Both forms are still
1074 understood but the latter is deprecated.)
1075 * CQL terms with no explicit index specified are now interpreted as
1076 cql.serverChoice instead of srw.serverChoice (which of course
1077 behaves exactly the same.)
1079 --- 2.0.7 2003/12/16
1081 MARC conversion can now generate ISO2709 output in another
1082 character set. yaz-marcdump uses this facility if you invoke it
1085 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1086 functions from there can be used from C++.
1088 --- 2.0.6 2003/12/04
1090 Frontend server now transfers memory from decoded packages to stream
1093 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1094 references to show up.
1096 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1097 the ZOOM Abstract API. The older names for the same options are still
1098 also supported for the benefit of old applications.
1100 ZOOM-C supports "implementationId" and "implementationVersion" options
1101 to go along with "implementationName". These allow the user code to
1102 specify identification strings to be sent to servers.
1103 Add OID for the new ExtLite attribute set.
1105 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1106 as requested/supplid by Ere Maijala <ere@atp.fi>
1108 For generic frontend server, reverse the order of
1109 "toolkit-supplied / application-supplied" strings sent as implementationId,
1110 Name and Version. Also, remove the spaces around the slash. This brings
1111 the GFS in line with the behaviour of ZOOM-C on the client side.
1113 Add function ZOOM_scanset_display_term.
1115 yaz-client shows scan displayTerm if present.
1117 Utility yaz-iconv is now installed by default along with the man page
1120 Extend configure check for OpenSSL to use pkg-config where available (such
1123 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1124 server to specify uid/gid/mask for socket using the format
1125 unix:[user=uid,][group=gid,][umask=mask,]file=path
1126 If file= is omitted the existing format is assumed, e.g.
1128 in which case the mask is 0666 (rw for everybody).
1130 Major restructure of YAZ source. All source in libyaz is in src directory.
1131 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1132 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1134 Added man page for utility yaz-marcdump (used to be called marcdump).
1135 yaz-marcdump is installed by 'make install'.
1137 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1138 of incoming package failed.
1140 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1142 Change prototype of odr_perror: add const to message string.
1144 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1146 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1147 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1148 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1149 DNS lookup. There should not be any compatibility problems with this
1150 assuming that blocking=1 or 0 is used.
1152 Fix bad reference in UNIX comstack in function cs_addrstr.
1154 Fix for compilation on AIX.
1156 The generic front-end server (server/seshigh.c) now supports returning
1157 Init diagnostics to the client in User-information-field, in
1158 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1161 --- 2.0.4 2003/09/04
1163 Allow any CQL relation (not just all,any,exact,scr).
1165 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1166 that features the same UI.
1168 Implemented command update0 in YAZ client which is equivalent to
1169 update but uses old of Ext Update ASN.1.
1171 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1172 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1173 Previously no OID was used for this info.
1175 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1176 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1177 returns 'malformed search term' otherwise.
1179 SortResponse member resultCount now set to NULL in sort handler of
1182 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1185 Add three new utility functions for translating OIDs between various
1186 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1187 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1188 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1189 char *oid_to_dotstring(const int *oid, char *oidbuf);
1190 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1192 Reverted modifications for ES Update definition for z_IU0Update
1193 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1194 is back to YAZ 2.0.2.
1196 String value attributes for CCL parser.
1198 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1199 which their FirstSearch server returns in Init responses, sometimes
1200 carrying useful diagnostic information when Init fails. This has the
1201 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1202 "z39.50/oclcui.asn", where its definition is somewhat different from
1203 what OCLC document on their web-site, as required to interoperate with
1206 Support for anonymous authentication in yaz-client. Use the command
1209 * Fix the OID of the Index Data-local "admin" Extended Service from
1210 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1211 the 1000, which indicates a locally-defined OID, was a mistake.
1213 --- 2.0.3 2003/06/20
1215 Fix CCL directive @case handling so that it affects string match for
1216 both CCL keywords and qualifiers.
1218 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1219 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1220 Decoder has been updated with ASN.1 changes as listed in
1221 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1222 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1223 z_IUUpdate, remains unchanged.
1225 ZOOM_record_get may now return a record in a specific character set.
1226 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1227 "from" is the character set of record as returned by target. "to" is
1228 the character set to be returned. If omitted, "to" is UTF-8.
1230 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1232 New ODR utility, odr_getelement, which returns name of element for
1233 which encoding/decoding failed.
1235 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1236 in cases where a required element was omitted.
1238 Bug fix: some MARC8 sequences were not converted.
1240 New ZOOM option "step" which specifies number of records to be
1241 retrieved in one chunk. Used in conjunction with "start" and "count".
1243 SRW support for yaz-client. Use scheme http: to use it, e.g.
1246 yaz-client no longer does (un)intelligent character set conversions
1247 by default. Can be enabled with charset and marc_charset commands.
1249 xmalloc trace fix for 64-bit systems such as DEC alpha.
1251 Solaris 2.6 compile fix.
1253 New function, cql_strerror() translates SRW error codes, as returned
1254 by cql_transform_error(), into human-readable English strings. Used
1255 in yaz-client diagnostics when appropriate.
1257 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1258 converts it into a type-1 query which is sent to the server. This
1259 makes CQL available for use with all Z-servers, as opposed to the tiny
1260 minority that can handle CQL queries themselves.
1262 --- 2.0.2 2003/04/28
1264 New Debian package layout similar to the Redhat Package layout.
1266 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1267 and search result respectively.
1269 --- 2.0.1 2003/04/25
1271 Redhat package is now several packages: libyaz (runtime libraries),
1272 libyaz-devel (development and documentation, and yaz (utility programs).
1273 Package spec file by Morten Bøgeskov.
1275 New member 'schema' in struct bend_fetch_rr which the name of requested
1276 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1277 handler MAY set this to reflect the schema of the returned record.
1279 New member 'display_term' in struct scan_entry. GFS now sets member entries
1280 and allocates scan entries to be filled by user scan handler. In previous
1281 version, entries member was allocated by the scan handler. That still works,
1282 but the GFS will ignore member display_term - assuming it was NOT set by
1283 the handler. The fact that the GFS now allocates the entries both allows
1284 for new members and makes a scan handler easier to write.
1286 Fix CQL lex buffer overflow.
1288 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1289 SRU default recordPacking is string.
1291 SRU protocol support for frontend server.
1293 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1295 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1297 Added scan for the ZOOM shell (zoomsh).
1301 * String Identifers for Schemas (Amendment 5).
1302 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1303 Old definition for schema
1304 Odr_oid *schema; /* OPT */
1309 Z_InternationalString *uri;
1310 #define Z_Schema_oid 1
1311 #define Z_Schema_uri 2
1314 * resultCount parameter to Sort Response (Amendment 1).
1315 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1317 Support for SRW 1.0 over HTTP. This is an optional feature and
1318 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1321 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1322 on the same port. SRW SearchRetrieveRequests are mapped
1323 to bend_init,bend_search,bend_fetch,bend_close.
1325 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1327 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1328 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1330 ZOOM connections are SRW based if schem http is used for hostname
1331 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1332 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1334 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1335 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1336 distance=n, order=true/false, relation=le, prox unit=word. If
1337 n is omitted, distance 1 is used.
1339 Fixed problem with C compiler include path in wrong order.
1341 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1342 on Solaris. Patch from Ko van der Sloot.
1344 New MARC decode API. All new functions operate on a yaz_marc_t
1345 handle. The most important new functions are: yaz_marc_create,
1346 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1347 decode and destroy respectively. Decoder can produce formats
1348 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1349 include/yaz/marcdisp.h.
1351 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1352 to UTF-8, UCS-32, wchar_t or Latin-1.
1354 * Prototypes for yaz_iconv_-functions moved to separate header
1355 include/yaz/yaz-iconv.h.
1357 Make a few private functions 'static' in unix.c. This prevents
1358 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1360 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1361 are set when Init Response is received.
1363 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1364 but returns diagnostic set as well.
1366 New function yaz_strerror which is a portable wrapper for
1367 strerror/strerror_r/GetLastMessage.
1369 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1370 is returned for MARC. If type is "oai", then OAI MARC is returned.
1372 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1375 --- 1.9.2 2002/11/26
1377 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1379 Fix bad race conditions on SIGTERM and terminate gracefully in
1382 Move retrieval (data1) module to Zebra since nobody seems to be
1385 Add GRS-1 render for ZOOM using same format as yaz-client.
1387 --- 1.9.1 2002/10/05
1389 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1391 Fix broken ESpec handling in data1 module.
1393 SGML reader parses comments and makes them part of the data1 tree.
1395 Added several type casts so that YAZ compiles as C++ code.
1397 ZOOM didn't handle PDU encoding failures properly.
1399 Added more Bib-1 diagnostics (approved extensions).
1401 GNU configure: better check for iconv.
1403 More portable use of accept, getpeername. Check for socklen_t. Use
1404 int/size_t if socklen_t is not defined.
1408 PQF parser rejects bad queries - including those with extra
1409 characters in them. PQF parser used to silently ignore that.
1410 Cleaner API for PQF added, which allows you to get detailed
1411 error information for bad queries (see yaz/pquery.h).
1413 Fixed bug in ZOOM_record_get for type "database".
1415 Implemented mini iconv library supporting conversions between
1416 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1418 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1420 --- 1.8.9 2002/08/20
1422 Fixed ZOOM C record cache so that preferredRecordSyntax and
1423 elementSetName is used to check for already fetched records.
1425 --- 1.8.8 2002/08/02
1427 Added three members in bend_initrequest structure to facilitate
1428 character set negotiation.
1430 Fixed a bug in frontend server that could cause indefinite
1431 loops under rare conditions.
1433 Revised character set utilities (charneg.h) so that encoding
1434 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1436 For PQF, directive @term <type> sets term type for Scan/Search.
1437 Here <type> is general, string, numeric, null. The term type
1438 is inherited - just like @attr.
1440 New call odr_set_charset that sets character set conversion for
1441 international-strings on a ODR stream. Prototype is:
1442 int odr_set_charset(ODR o, const char *to, const char *from);
1443 The InternationalString is still represented as C string in YAZ
1444 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1445 won't). On the protocol level, you can use any encoding.
1447 Support for UNIX sockets in ZOOM.
1449 Solaris recv sometimes returns errno == ENOENT. It is treated as
1450 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1452 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1453 both client and server. Code by Morten Bøgeskov.
1455 --- 1.8.7 2002/05/22
1457 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1458 that they can be used directly from Visual Basic. You must recompile
1459 your windows APP if you're using ZOOM.
1461 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1462 Commands "lang" and "charset" sets language and character set respectively.
1463 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1464 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1466 Attributes from multiple CCL fields may be OR'ed rather than merged
1467 using directive "@field or". Fields are still merged by default -
1468 equivalent to "@field merge".
1470 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1473 Fixed bug in zget for parameter ExtendedServicesResponse.
1477 --- 1.8.6 2002/03/25
1479 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1481 Client displays USR.1:SearchResult-1 (hits per term).
1483 Additional Search Info for search in Generic Frontend Server.
1485 Fixed CCL parsing of "field=s".
1487 WIN32 installer - using the excellent NSIS software from nullsoft.
1489 Fixed CCL parsing of "field = - <number>".
1491 Added function yaz_marc_decode that decodes MARC for line mode
1492 display or XML (similar to that used by JZKit).
1494 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1495 Z39.50. But ISO/ILL was, however.
1497 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1498 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1500 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1501 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1503 --- 1.8.5 2002/02/03
1505 New YAZ client features: Command completion and new commands:
1506 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1507 Code provided by Jacob Poulsen.
1509 New call oid_trav, that visits all registered OIDs via callback.
1511 Function ZOOM_record_get now returns const char pointer rather than
1512 void pointer. It saves a lot of type casts.
1514 For YAZ client, command "auth" now allows you to set authentication
1515 in IdPass style. It is enabled when three tokens are given - order
1516 is user, group and password.
1518 Fix memory leaks in MARC record handling for ZOOM.
1520 New option for YAZ client, -k <kilobytes> that sets
1521 maximum record size. Similar to -k option for generic frontend
1522 server and yaz-ztest.
1524 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1526 Prefix query parser reports "fail" when bad attribute set is given.
1528 Fix in MARC decoder. Proximity logging. Fix for attribute set
1529 in scan handler for server. Patches by Shigeru Ishida.
1531 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1534 Configure option --with-openssl=<dir> now works when a directory is
1535 specified. Patch provided by Morten Bøgeskov.
1537 New option for YAZ client, -u <auth>, that sets authentication.
1539 ZOOM fix: error information was sometimes "missing", since error
1540 was cleared/reset too when it shouldn't.
1542 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1544 --- 1.8.4 2002/01/04
1546 Scan for ZOOM API. New object ZOOM_scanset. New functions
1547 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1548 ZOOM_scanset_destroy.
1550 New ZOOM function, ZOOM_connection_last_event, that returns type
1551 of last event (such as "receive data", "send data", "apdu received",
1554 New ZOOM option, schema, that specifies schema for retrieval.
1556 New CCL feature. Qualifiers can be aliases for one or more
1557 other qualifiers (if more than one is given, OR is used).
1559 ZOOM uses named result sets if target supports it.
1561 Two new YAZ client commands: . (dot, which sources a script of YAZ
1562 client commands), and ! (to execute shell command.). Implemented
1565 Working on Debian packages.
1567 --- 1.8.3 2001/11/19
1569 YAZ client enables named result sets only if target supports it.
1571 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1573 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1574 with key="host" to get same result.
1576 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1577 Function Z3950_resultset_record(s) returns references to records
1578 "owned" by resultset. To become owner use Z3950_record_clone.
1580 Function z_ext_record handles Extended Services. Thanks to
1583 --- 1.8.2 2001/11/12
1585 CCL Parser fix: ignore token comma when dealing with and-lists.
1587 Documentation updates for COMSTACK.
1589 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1590 Changed prototype Z3950_records. For some functions, int parameters
1591 were changed to size_t.
1593 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1596 New MARC decode/display function, marc_display_exl, which properly rejects
1597 non-ISO2709 records. YAZ client uses it.
1599 --- 1.8.1 2001/10/29
1601 Fix bug: local attribute set wasn't set correctly in PQF strings.
1605 * Old Z39.50 codecs no longer supported.
1607 Added ZOOM C binding. See http://zoom.z3950.org/
1609 Renamed states for COMSTACKs to avoid confusion with events.
1611 Implemented cs_look and proper cs_rcvconnect.
1613 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1615 Configure detects POSIX threads on OpenBSD.
1617 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1618 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1620 When error is returned from present handler, non-surrogate diagnostic
1621 is returned in present response (and fetch handler is no longer called).
1623 * Minor adjustments to pquery parser (PQF). Token characters may be
1624 escaped by using backslash (C-style).
1626 PQF parser allows string attribute values to be specified. For @attr,
1627 non-numeric characters after the equal-sign are treated as strings
1628 (e.g. @attr 9=title).
1630 CCL trunction character may be defined (@truncation in file)
1632 * function zget_ExtendedServicesRequest sets waitAction to
1633 waitIfPossible (was wait).
1635 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1638 CCL operator names may be set in field definition files (CCL_bibset).
1639 See ccl/bib1 for an example.
1641 Fixes in ASN.1 compiler for C++ compatibility.
1643 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1644 and "op_or" to avoid conflict with C++.
1646 Fixed problem with GNU readline detection on Redhat 7.0.
1648 Added step-size for Scan backend handler.
1650 Fixed bug that made the frontend server crash when no attribute
1651 set was specified for scan.
1653 Front-end server automatically switches to original working directory
1654 when installed as an NT service. Previously -w had to be specified to
1657 Added extended attributes for retrieval module (data1), so that data1
1658 records carry d1_readXML/SGML attributes. d1_read also supports
1659 null-data rules ( <tag/>)
1661 On UNIX when POSIX threads are available, a separate library libyazthread
1662 is created. Programmers should link with that library and the yaz library
1663 when using threads. The reason for the split was that some applications
1664 on Linux, such as Apache, doesn't work well when using shared objects that
1667 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1668 (or any frontend server) in SSL mode by specifying ssl: followed by
1669 address. Only tested on UNIX.
1671 Added feature for CCL module. Virtual structure s=al or s=ol generates
1672 and-list and or-list respectively instead of phrase search.
1676 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1677 log_mask_str. This was done to avoid name conflicts with other libraries
1678 (such as other PHP extensions).
1680 Added raw OID member for preferred record syntax (request_format_raw)
1681 and returned record syntax (output_format_raw) for backend fetch method.
1683 Config file yaz-config now accepts options so that it returns specific
1684 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1686 Shared library support for UNIX using GNU libtool.
1688 * Modified backend interface. Request/Response struct's replaced by
1689 one read/write C struct. For example bend_fetchrequest and
1690 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1691 Every handler - even search has to be registered in bend_init
1692 handler. This means that the YAZ library no longer refers to
1693 external functions and it makes it possible to make the whole
1694 thing a single DLL/SO.
1696 Added Segment handler for backend server.
1698 Added Zmbol/Zebra administrative functions to YAZ client.
1700 Threaded frontend server on UNIX (when POSIX Threads are available).
1701 Starting the server with option -T enables multi-threading.
1705 Added configure option --enable-comp/disable-comp to control use
1706 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1707 located in sub directory asn.
1709 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1710 in ${exec_prefix}/bin along with the other programs yaz-client and
1713 GNU automake used to maintain makefiles.
1715 Added several OID's.
1717 Changed retrieval module so that we can load records with no abstract
1718 syntax defined. Tagpaths in these records are fully composed of string
1721 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1725 On UNIX, the generated makefile now supports a proper 'make install'.
1726 The prefix can be set via GNU configure to set the install location
1727 (default is /usr/local).
1729 * YAZ programs client and ztest were renamed to yaz-client and
1730 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1731 locations, such as /usr/bin,/usr/local/bin,etc.
1733 * YAZ Header files were moved from include to include/yaz. YAZ Header
1734 files are referred to as include <yaz/log.h> rather than <log.h>.
1735 The YAZ include path (-I ..) is therefore the same as before. Programmers
1736 should update their #include statements or use -Ipath/include/yaz
1737 instead. The main motivation for doing this change is that YAZ header files
1738 can be installed in "standard" locations /usr/include,/usr/local/include
1739 without introducing conflicts, since ALL YAZ header files are stored
1740 in subdirectory yaz (under /usr/include for example).
1742 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1743 rather than project/workspace files. We switched because project files
1744 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1747 Changed name of logging function, logf, to yaz_log, to prevent name
1748 clash with some math-log functions. The YAZ header log.h defines logf
1749 to yaz_log (#define) so there should be no incompatibilities by this
1752 Added bend_start/bend_stop handlers for server. These handler are
1753 called on start/stop of server. For windows they are called whenever
1754 a service is started/stopped.
1756 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1757 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1758 in util/yc.tcl. The auto-generated C code structures are, in a few
1759 cases, incompatible with the old decoders. There are differences in the
1760 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1761 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1762 The preprocessor variable ASN_COMPILED is defined when the compiled
1763 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1764 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1765 wish to use the old encoders/decoders you can specify --disable-yc
1768 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1769 version so that it supports both new - and old version of DB Update
1771 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1772 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1773 change. The name parameter can be set to 0 in which no name is specified
1774 for the construction. The macros odr_implicit and odr_explicit sets name
1775 parameter to zero for the construction involved. New macros
1776 odr_implicit_tag and odr_explicit_tag are similar to the others,
1777 except that a name parameter is added. For programmers' that don't use
1778 ODR they probably only need to change the call to z_APDU and z_External.
1780 Added access control facility by interfacing the TCP wrapper library.
1781 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1782 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1783 name of the daemon and enables the access control as specified in
1784 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1786 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1787 den Dool <H.M.vdnDool@kub.nl>.
1789 Added reference ID parameter to most functions in server API - refer
1790 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1792 Changed name of ccl library to libccl.a (was ccl.a).
1794 Fixed bug in decoder for Explain (Category TargetInfo).
1796 Added support for GNU readline in client. Thanks to Jacob Poulsen
1797 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1799 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1800 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1801 IMPLEMENTATION! This change was made to the development version before
1802 the ZIG decided to retract the amendment. If any users MUST be
1803 compatible with the original Update definition, PLEASE CONTACT US, and
1804 we will include a separate definition corresponding to the old Update
1805 ES. Note that because of the change to the ASN.1 of the
1806 TaskPackageRecordStructure we cannot define a single structure that
1807 will support both versions.
1809 * Added const modifier to buffer parameter for some ODR/BER encoding
1810 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1811 completeWAIS, odr_dumpBER.
1813 Fixed bug in client.c which caused a crash when a scanResponse didn't
1814 contain positionOfTerm.
1816 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1817 * will cause an error in a client if a non-YAZ target sends both a
1818 * list of Scan entries and non-surrogate diagnostics.
1820 Retrieval module enhancements. Tag sets may be typed in the reference
1821 to it. From the .abs-file the "tagset" directive takes a third optional
1822 integer type for the tag set referenced. From a .tag-file the "include"
1823 directive takes a third optional type as well. The old "type" directive
1824 in the tag set itself is still recognized but acts as the default type
1827 Backend interface change. Individual Scan terms returned from bend_scan
1828 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1829 in include/backend.h.
1831 Retrieval module enhancements. Multiple tag sets and attribute sets may
1832 be specified in abstract syntax specs. Revised the error/warning for
1833 logging messages reported by the retrieval module when reading the
1836 Object Identifier system (oid_..) changed. The API is backwards
1837 compatible but the oid-routines now allocates new OID's when needed.
1838 Raw OID's may be specified in oid_getvalbyname.
1840 YAZ now uses GNU configure to generate Makefile(s).
1842 * Minor changes in some of the member names of DeleteResultSetRequest and
1843 DeleteResultSetResponse. See include/proto.h.
1845 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1846 and added member 'languages' in TargetInfo (which was missing).
1848 Changed the way attribute sets are handled in the retrieval
1849 module. These are now cached, just like the abstract syntaxes
1852 Changed YAZ so that it links with compiled ASN.1.
1854 Added Explain-schema definitions and mapping routines. The following
1855 Explain categories have been implemented: AttributeDetails,
1856 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1858 Fixed minor bug in Windows version of Server Library.
1860 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1862 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1864 Added EXTERNAL: UNIverse Resource Report (non-standard).
1866 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1867 ENUMERATED and SET OF.
1869 * Added 'const' to some of the char pointer arguments for the
1870 functions, data1_read_node, data1_getelementbytagname,
1871 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1874 Fixed bug in data1_insert_taggeddata - the last_child member of
1875 parent wasn't initialised.
1877 * Changed data1_read_record and data1_read_node so that the supplied
1878 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1879 doesn't refer to any parts of the "SGML"-buffer.
1881 Fixed bug in server library (Windows version of statserv_remove).
1883 * Changed code so that it compiles as C++. The type definition
1884 of Odr_fun which is a member of Odr_arm was changed. The result is,
1885 that an explicit typecast is needed for the fun pointer when
1886 using Odr_arm - as in:
1887 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1889 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1891 Implemented the new structured date and time definition as approved
1892 by the ZIG. Added schemaId element to the specificTag in Espec-1
1893 (also approved at the last ZIG). Thanks to RVDM.
1895 Added some Object identifiers (RVDM).
1897 Changed the Update Extended Service (RVDM).
1899 Added command "refid" to client which specifies referenceId for
1900 the following requests.
1902 Implemented extended service handling for server. See ztest.c
1903 for an example as well as backend.h. New handlers are registerd
1904 in the Init handler.
1906 * Changed interface for sort in server.
1908 Added new members to statserv_options_block. It allows a server
1909 to read options from another source than just the command line. Thanks
1910 to Charles Woodfield.
1912 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1913 renamed to zboolean. Some C++ compilers complained about the name.
1915 Minor changes to gils.abs. Added index 's' (sort) on title
1916 and date/time-last-modified.
1918 --- 1.4pl2 1998/1/30
1920 Fixed bug in server library regarding inetd mode (-i). This bug
1921 was introduced by release 1.4.
1923 --- 1.4pl1 1998/1/29
1925 Added sort facility in client and backend server interface.
1927 Fixed problem with dependencies in Makefile(s).
1929 Fixed bugs for encoders/decoders of extended services and
1932 Implemented sub-tree feature for schemas. Sub-trees are
1933 referenced in *.abs-files. See explain.abs for an example
1934 of the use of this feature.
1936 Modified bib1.att; local attributes for ANY didn't include
1937 ANY itself (only affects use of the retrieval module).
1939 Fixed bug in plain SGML reader in function data1_read_node:
1940 tags with prefix "var" was incorrectly interpreted as variants.
1942 Added feature "sub-schemas" to enable references to - and definitions
1943 of - group of elements.
1945 * Removed member parent from type data1_element (in data1.h).
1947 Implemented function odr_nullval() that returns the value of
1950 * Removed member num_children from data1_node (in data1.h).
1952 Made NT service interface part of the server library. The
1953 function statserv_main uses the NT service when required and
1954 calls the statserv_start / statserv_close routines.
1956 Routine zget_SearchRequest and zget_PresentRequest fills
1957 resultSetName/Id member with "default" instead of "Default".
1959 Fixed memory leak in server. Request queue member wasn't freed.
1961 Fixed nmem_exit so that memory is freed.
1965 Revised the CCL parser utility to be thread safe.
1967 Added function, oid_ent_to_oid, to replace the function
1968 oid_getoidbyent, which is not thread safe.
1970 * Added nmem_init and nmem_exit to initialize and release
1971 NMEM resources. Function nmem_init should be called once in the
1972 initial thread before NMEM/ODR is used. statserv.c and client.c
1973 have been changed accordingly. The change was necessary to make
1974 NMEM thread safe. The NMEM memory pool is shared amongst threads
1975 in a process. Unix-based applications will still work fine without
1978 Added NT Services interface for the the Z39.50 (statserv) Server.
1979 Refer to the ztest.c source on the usage.
1981 Windows 95/NT port using MSVC5.0. Project files are included in the
1984 * Defined new 'global' handle for the retrieval (data1) system. The
1985 new handled, data1_handle, describes the state of the data1 system.
1986 This handle is passed as first argument to virtually all
1987 data1 related routines. The functions data1_create and data1_destroy
1988 creates and destroys a data1 handle respectively.
1990 Added ODR encode stream member to all backend request structures
1991 init, search, scan etc. This stream should be used to allocate all
1992 memory used for the response when thread safe operation is needed.
1994 Changed the comstack utility, cs_addstr, to be thread safe. The
1995 returned hostname string returned by the function is now part the
1998 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1999 function. The cs_straddr takes a COMSTACK handle as argument, so this
2000 function must be used after cs_create and before bind/connect.
2001 This function is thread safe.
2003 Moved test server to 'ztest' directory - generic server code still
2004 in 'server' directory.
2006 Made prefix query (pquery.c) utility thread safe.
2008 Added new function modifier YAZ_EXPORT to 'export' public DLL
2009 functions when using windows (see include/yconfig.h).
2011 Added definitions to the OID database (util/oid.c) (RVDM).
2013 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2015 Added call to ccl_rpn_delete in client program.
2017 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2018 release of RPN structure.
2020 Added support for C++, headers uses extern "C" for public definitions.
2021 With input from RVDM.
2023 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2024 Thanks to Ronald van der Meer (RVDM).
2026 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2028 Added support for private extensions to the OID database
2029 (oid_setprivateoids()). Thanks to RVDM.
2031 Added optional, physical ANY (key replication)
2033 Fixed null-reference problem in GRS-1 output filter.
2035 Proximity operator added to Prefix Query Format (PQF).
2037 In test client command "base" accepts multiple databases.
2039 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2043 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2045 Smallish bug-fixes in the new encoders/decoders (explain).
2047 Bug fixed in DeleteRequest.
2049 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2051 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2053 Added SOIF syntax (using private OID for now) to retrieval module and client.
2055 Added Update extended service.
2057 Added SearchResult-1 additional info structure.
2059 Added optional CCL (ISO8777) interpreter as separate module. Available
2062 --- 1.2 1996/6/10 (1st anniversary release)
2064 Added Summary record syntax. Lightly tested.
2066 Added OPAC record syntax. Untested.
2068 Added ResourceReport service encoders/decoders. Untested.
2070 Fixed bug in z_Unit - wrong tagging on unitSystem.
2072 Fixed bug in the DiagRecs decoder.
2074 Added options for max PDU size and session timeout to frontend-server.
2076 Added documentation of query-language parsers and other supporting utilities.
2078 [frontend-server] Added Attribute set to the bend_scanrequest API.
2080 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2081 surrogate diagnostics were generated.
2083 [retrieval] Allow multiple local values for attribute.
2085 [retrieval] Allow multiple attributes per element in .abs files. index type.
2087 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2089 --- 1.1pl2 1996/4/10
2091 Minor changes, mostly specific to Zebra's requirements (retrieval)
2095 Repaired bug in frontend server when running multiple listening
2096 endpoints in dynamic mode.
2098 z_External() now won't break if a known, ASN.1 value comes encapsulated
2099 in an octet-string. The value will pass through unmodified in an Odr_oct.
2101 Added a bit of code to the demo client to decode & display
2102 ASN.1-structured records represented in the octet-aligned branch of
2103 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2105 Added z_ext_getentbyref() to the ASN module. Doc updated.
2107 * Completed the SCAN definition in the ASN module. This may break SCAN
2108 code based on older YAZ-versions at compile-time. The fix is easy -
2111 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2112 under the SCAN definition. Remember to initialize this, server-people.
2114 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2115 that this does not extend to ODR and ASN.
2117 Comstack allows insertion of established socket (primarily for
2118 inetd-operation of servers). Doc updated.
2120 Front-end server can now start from the inetd in TCP mode. Doc
2123 --- 1.0pl4 1996/1/24
2127 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2128 the rank and record number.
2130 Adjustments to the frontend server.
2132 Fixed diagnostic BER dumper. It ignored the file argument.
2136 Various changes to retrieval module.
2138 Changed the union discriminators of the protocol files from enums to
2139 ints paired with #defines.
2141 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2144 *Changed operator in the RPN structure to 'roperator', again to avoid a
2147 Fixed problems in Explain decoders/encoders.
2149 --- 1.0pl2 1995/12/6
2151 Memory bug in log module fixed.
2153 --- 1.0pl1 1995/12/5
2155 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2157 Bug in Explain DatabaseInfo module fixed.
2159 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2163 The shift to v1.0 signals that we now consider the *core* functionality
2164 of YAZ reasonably stable (the core being more or less equivalent to
2165 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2166 tested (Explain not at all - though that will happen soonish).
2168 Minor changes to code to support Windows port.
2170 Various minor changes after we're getting to use GRS-1 & co. more.
2172 Added Espec-1 format.
2174 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2175 of the protocol and it cannot be selected when encoding (maps into 'string'
2176 when decoding). Needed to talk to some servers.
2178 Demo client can request simple element set names.
2180 Added Diagnostic Format encoders/decoders.
2182 Added simple Close handling to frontend server (no hooks for resource
2183 reporting yet), and demonstration client.
2185 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2187 --- 1.0b3 1995/08/24
2189 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2190 handled incorrectly when records were requested in the searchResponse. This
2191 will only affect you if you use the frontend-server.
2193 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2194 Test-client will ask for and print GRS1. Ztest will return dummy records
2197 Added Explain encoders/decoders to the service-level API. Untested.
2199 Added Extended Services: Item Order encoders and decoders to the Service-
2200 level API. Untested. We could use a recent copy of the pertinent bits
2201 of the ILL protocol to add those bits.
2203 Added diagnostic format 1 encoders/decoders to the service-level API.
2206 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2207 odr_cons.c, which causes a more correct output.
2209 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2210 was always set to 0 when no records were requested in the searchRequest.
2212 * Added better external-handling. This shouldn't harm old code that
2213 *encodes* externals. It can break code that looks for a
2214 'single-ASN1-type' representation, since those types that are known
2215 are now decoded immediately. Look at the SUTRS sample code in
2216 seshigh.c and client.c. Documentation updated.
2218 Handling of structured records in bend_fetchresponse. Length -1 marks
2219 structured record, type is deduced from format field.
2221 --- 1.0b2 1995/06/27
2222 Fairly quick maintenance release to add SUTRS support.
2224 Fixed handling of SUTRS records in the demonstration client.
2226 * Added format field to the bend_fetchrequest and bend_fetchresponce
2227 structures of the backend API (frontend server). When the record is
2228 returned, the value of the format field is mapped to an OID. The
2229 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2230 of the record. The special value VAL_NONE in the bend_request means
2231 that no specific format was requested by the client. Documentation
2232 updated accordingly. Test server (ztest) will return a fixed dummy
2233 SUTRS record if your client requests SUTRS.
2235 Documentation updated accordingly.
2237 You can now set external libraries and RANLIB support in the top-level
2241 First public release.
