3 Fixed bug #1157: yaz-client does not read .yazclientrc from current
4 directory. yaz-client now reads commands from file given by option -f
5 if specified; then tries to read .yazclientrc in current directory.
6 Failing that, it reads .yazclientrc from user's home directory.
8 Added support for correlationInfo Note and ID for Record Update via
11 Added yaz-client command querycharset which specifies character set for
12 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
13 (termListAndStartPoint).
15 Charset ISO5428:1984 is an alias for ISO5428-1984.
17 Implemented a way to perform scan in a result set using Z39.50. This
18 is achieved by attaching the result set name in the characterInfo
19 (type InternationalString) of OtherInformation in the Scan Request PDU.
20 The result set is identified in the otherinformation by the new OID:
21 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
22 This allows for scan in result set and faceted search . Zebra did some
23 of this in the APT term using attribute type 8 and value being result
24 set. Using the OtherInformation approach for this is cleaner and easier
25 to work with in proxies and the like. This facility can be used in
26 yaz-client using new command setscan which takes a result set as first
27 argument, start position (APT) as second.
29 Changed decoding of SRU XML packed records to deal with servers that
30 have recordData with XML data with multiple root nodes. Also make
31 comparison for recordPacking case insensitive. Again, one server
32 returns "XML" where others return "xml".
34 For SRU responses allow Content-Type application/xml as well as text/xml.
38 Fixed bug in character set conversion of BER strings. Bug introduced
43 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
45 For OID class, use oid_class consistently.
47 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
50 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
51 character set for bibliographic information interchange". By Giannis Kosmas.
53 Added documentation on new OID API.
57 Changes to generic frontend server interface: added new member
58 'query_charset' for bend_initrequest structure. A backend init handler
59 should set this member to its native character set for query terms.
60 When defined, the frontend server logic will announce this character set
61 to a client if the negotiationModel bit is set by the client. All server
62 implementors are encouraged to specify this. If a backend server does not
63 specify this a warning is issued using yaz_log(YLOG_WARN,..).
65 Added CCL utility to remove terms (stop words) from resulting RPN
66 tree. This is handled by functions with prefix ccl_stop_words_ .
68 New ZOOM C option, "rpnCharset", which allows client-side conversion of
71 Clean-up the CCL API. Moved some internal structures from ccl.h to
72 private header cclp.h. Changed ccl_parser_create so that a Bibset must
73 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
74 This is replaced by ccl_parser_find_str which takes a string instead.
76 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
77 libyaz.la is the core of YAZ except the generic frontend server and
78 does not depend on POSIX threads anymore. libyaz_server.la is the
79 generic frontend server facilities and uses POSIX thread functionality
80 if available. The libyaz.la no longer depends on POSIX threads because
81 the number of global structures is limited. NMEM no longer re-uses blocks
82 between threads ; it simply free's memory immediately but allocates in
83 "large" chunks as usual. We don't expect any performance penalties
84 because of this. The yaz_log system is still using a global log_level so
85 caution must be taken when modifying it with yaz_log_init_.. +
86 yaz_log_mask_str. This, however, should not cause any trouble because
87 these functions are called during initialization of application code
88 anyway. `yaz-config --libs server` returns libs for server applications;
89 `yaz-config --libs` returns libs for non-server applications.
91 New OID database - with public definitions in oid_db.h. Removed old OID
92 database including the head oid.h and definitions such as enum oid_value
93 and struct oident. The new OID database uses the same string names as
94 before but the 'protocol' is gone. There are now only two representations
95 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
96 converts from string to OID; functions with prefix yaz_oid_to_string
97 converts the other way.
99 Change to emit_term() in CQL-to-PQF query translation: when a term has
100 the /regexp relation modifier, do not process it for leading and
101 trailing "^" and "*", which have quite different meanings in regular
104 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
105 write handlers no longer carries a 'last' parameter. This will make
106 yaz_iconv flush "less" characters. A flush is performed by call to
107 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
109 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
110 removed, because function yaz_query_to_wrbuf does the same.
112 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
113 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
115 Deprecated MARC utility functions removed.
117 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
120 Branch split: YAZ_2_1_55_branch
122 --- 2.1.54 2007/03/16
124 Fix to ZOOM-C so that transparent reconnection is properly handled on
125 connections that are in asynchronous mode.
127 Fixed compilation on OpenBSD 4.0.
129 Large strings in GRS-1 records are now properly displayed in yaz-client.
131 Added character conversion support for "advancegreek"; based on patch from
134 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
135 sequence is met. Before the error was not set so it would be unknown.
137 Adjust yaz-marcdump MARC reader so that it skips until record separator
140 --- 2.1.52 2007/03/07
142 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
143 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
144 fd_set structure used as a bitmask for the FDs to be selected on.
146 Using ACX_PTHREAD macro to check for POSIX threads.
148 Fixed have-vsnprintf check.
150 --- 2.1.50 2007/02/23
152 Fixes for configure on BSD. Bug #900.
154 Added snprintf/vsnprintf wrappers for systems that don't have
155 limits (heavens forbid).
157 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
158 created before all previous tasks were completed and removed from the
159 task queue, the new task could be removed by a mistake.
161 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
163 Implemented pass-through CQL-to-PQF conversions. Bug #861.
165 Fixed bug #832: Problem with MARC/charset in yaz-client.
167 Fixed bug #668: save command line history for yaz-client.
169 Fixed bug #830: pkg-config support.
171 --- 2.1.48 2007/01/23
173 Extended ZOOM result set options with two options that may be read by
174 a client: resultSetStatus and presentStatus with values as specified for
176 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
178 Fixed bug #827: Using SSL fails on Debian etch.
180 Fixed bug #826: Weird looking chars for set of MARC records.
182 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
183 that is treated as an ItemOrder with itemRequest being an XML document
184 external. The value of "doc" is the content.
186 Extended the GFS search facility. New member of bend_search_rr
187 'estimated_hit_count' signals that hits is known to be an estmate
188 (higher or lower than real hit count). New member 'partial_resultset'
189 signals that the search was partial (hit count is lower or equal than
190 real hit count). For Z39.50, the information is stored in resultSetStatus
191 member of SearchResponse APDU. For SRU, the information is signalled
192 via SRU diagnostic 59: "Result set created with valid partial results
195 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
197 --- 2.1.46 2007/01/13
199 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
201 Added ZOOM_connection_peek_event.
203 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
204 the following new functions:
205 ZOOM_event_nonblock, ZOOM_connection_process,
206 ZOOM_connection_get_{socket,mask,timeout},
207 ZOOM_connection_fire_event_{timeout,socket}.
208 The existing blocking event handler, ZOOM_event, is a wrapper for the
209 + blocking ZOOM_event_sys_{poll,select}.
211 Implemented function ccl_xml_config which parses XML version of CCL
212 configuration (bug #798).
214 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
216 Added timings utility (yaz/timing.h)
218 --- 2.1.44 2007/01/03
220 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
223 Fixed bug #779: Rotation of apdu.log fails.
225 Fixed for character set conversions:
226 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
227 Honor G1 set in MARC-8 decoding.
229 --- 2.1.42 2006/12/17
231 Fixed bug #775: char conversion does not handle Alternative UTF-8
234 Implemented function yaz_marc_read_line which parses MARC line format
235 records. There is a wealth of formats out there. So far, this function
236 reads line records produced by yaz_marc_write_line.
238 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
239 more generic and easier to remember(!) options: -i format and -o format
240 which specifies input format and output format respectively - where
241 format is one of "marc", "marcxml", "line", "marcxchange".
243 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
244 does not print anything except warnings for records.
246 For yaz-marcdump, added support for MARC split into files (-s) with a given
249 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
250 spec, at http://www.loc.gov/standards/sru/record-update/
251 This has changed the binary layout of the following structs:
252 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
253 bend_update_rr . Patch by Ko van der Sloot.
255 Added GFS utility function bend_assoc_is_alive which returns 1 if
256 association is still alive (client is connected); 0 otherwise (client
257 closed connection). This allows busy servers to stop working for
260 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
261 been a separate piece of software. This version of ziffy has been modified
262 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
264 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
266 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
267 Client code may now interrogate options such as "init_opt_sort" to
268 find out whether the server claims to support various options.
270 --- 2.1.40 2006/11/27
272 Added utilities yaz_{set,get}_esn to set/get element set name from
275 Removed the build of libyazthread.la. The libyaz.so is the threaded version
276 of YAZ and has been so since YAZ 2.1.10.
278 Implemented ZOOM_record_error which returns error information for
279 record (surrogate diagnostic).
281 --- 2.1.38 2006/10/31
283 Updates for SRU Update by Ko van der Sloot:
284 1. Changed name from "operation" to "action"
285 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
286 versions in the code, marked as 'backward compatible'.
287 3. Added diagnostics for SRU Update.
289 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
291 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
293 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
295 For GFS, fixed problem with SRU diagnostic 'First record position out of
296 range' being issued for 0 hits.
298 zoomtst10 part of Windows Build.
300 --- 2.1.36 2006/10/13
302 Implemented yaz_filepath_comp which splits a path into file path
303 components (required by Zebra 2.0.3+).
305 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
306 BSD inspired license until now so this should not have any real impact on
307 anybody. See http://www.opensource.org/licenses/bsd-license.php
309 Fixed bug #687: Missing log lines.
311 Fixed bug #678: CQL to PQF translation does not preserve double-quote
314 Fixed bug #689: SRU diagnostics to be added.
316 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
317 whether a connection is idle (no more work do do).
319 --- 2.1.34 2006/10/04
321 Change type of optval from long to int for invocation of setsockopt with
322 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
324 Added support for specifying the max log file size for the Generic
325 Frontend Server. The size is given with option -r.
327 --- 2.1.32 2006/09/21
329 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
331 --- 2.1.30 2006/09/17
333 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
336 Fixed bug in Generic Frontend Server that could cause a server to stop
337 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
339 For the generic frontend server, the maximum record size is used as maximum
340 size of incoming packages (SRU + Z39.50). The value until was previously
341 only used in Z39.50 Init negotiation and, later, in a session controlled
342 sizes of records returned. This is controlled using -k option. It can be
343 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
345 --- 2.1.28 2006/09/04
347 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
350 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
352 New option for yaz-marcdump -lpos=value which allows setting a portion
353 of MARC header to a certain value.
355 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
357 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
358 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
360 --- 2.1.26 2006/08/15
362 Fixed problem with SRU mode type (soap, get, post) for yaz-client
365 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
367 --- 2.1.24 2006/08/08
369 Fixed MARC ISO2709 encoding routines to deal with character set
372 Minor changes to GFS logging. Database included in search request log
375 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
376 cached/multiple records.
378 Shared libraries are built by default on Unix+configure.
380 Changed cql2pqf transformation to use a different evaluation order. The
381 new order is: always, relation, structure, position, truncation, index
382 and relationModifier. Old order was: always, relation, relationModifier,
383 structure, index, position, truncation. Note that the the latter ones
384 override former ones for identical attributes.. The new scheme means that
385 it is possible to override any existing attribute with a relationModifier.
386 And also that it is possible to override everything for the index rule
387 (except the ones listed in relationModifier). No order is perfect but this
388 one, we believe, covers more real cases.. The "always" should have been
389 called "default", since the attributes there can be overridden with all
392 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
393 compilation phase, but also for yaz-config --cflags output. This allows
394 us to have public headers with Libxml2 stuff in them . It should also,
395 eventually, make Libxml2 checks redundant in packages using YAZ, such
398 --- 2.1.22 2006/06/15
400 Changed SRU update structure bend_update_rr so that SRU diagnostics are
401 stored in uri, message and details.. Previously diagnostics were stored
402 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
403 compatibility.. but he's probably the only one affected, so.
405 Added support for CCL, compiled on the client side, in ZOOM-C. This
406 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
407 input; the resulting query objects can be used for for searching with
408 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
410 YAZ' configure searches for OpenSSL by default.
412 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
413 SL_CTX_use_certificate_file. See
414 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
415 for more info. Thanks to Ko van der Sloot.
417 --- 2.1.20 2006/06/02
419 Bug #600: SRU GET, POST support for yaz-client. Introduced
420 command 'sru' which selects method SOAP/GET/POST.
422 Allow missingValueAction to be specified for the sortspec string -
423 function yaz_sort_spec. By default, the missing value action is null.
424 Use ! to specify "abort". Use = followed by stringvalue to specify default
427 Ensured that Present-handler (if defined) is called in GFS before any call to
428 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
429 searchRetrieve requests.
431 Documentation for YAZ is now based on the Docbook XML/XSLT using
432 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
433 is no longer depending on jade/openjade or docbook-to-man scripts.
434 PDF is no longer part of the distribution - but can optionally be
435 made using DSSSL/jadetex or FOP.
437 Added retrieval handling support in Generic Frontend Server to support
438 conversion between MARC/XML as well as XSLTtransforms. See
439 etc/yazgfs.xml for an example.
441 Added Authentication support to Generic Frontend Server in SRU
442 mode. Authentication using HTTP Basic is supported, as is the use
443 of 'x-username' and 'x-password' parameters in the request itself.
445 Added support for a new character set MARC8s identical to MARC8 except
446 that it converts combined characters to single Unicode characters in the
447 Latin-1 range (when possible).
449 --- 2.1.18 2006/04/24
451 ASN.1 compiler 0.4: generates brief Doxygen file header for
452 generated .h/.c files.
454 Utility yaz_iconv now supports conversion to MARC-8.
456 New facilities for the MARC module. The reading - and writing of
457 content are separate methods for the yaz_marc_t handle. The following
458 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
459 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
460 format). Write functions have prefix yaz_marc_write_.. The existing
461 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
462 available. Removed support for OAI-MARC and simplexml (not the
463 simplexml from PHP5).
465 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
466 to be returned for this connection.
468 --- 2.1.16 2006/03/31
470 Allow multiple languages and charsets to be specified with
471 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
472 negcharset iso-8859-1,utf-8
474 Translation of proximity nodes from CQL into PQF now works.
476 Moved to automake 1.8, 1.9.
478 Added function yaz_log_set_handler which allows a log handler to be
479 installed. This handler will be called for all log messages. Output
480 to file is also produced; but that can be disabled by passing NULL
481 fname to yaz_log_init_file.
483 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
485 For SRW (including GFS), accept application/soap+xml as content-type
488 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
489 produces NO stylesheet reference even if a default stylesheet is specified
492 --- 2.1.14 2006/03/14
494 Updated Windows package to include yazd.dll + yazd.lib for the
495 Development component.
497 If the environment variable YAZ_LOG is set, then it is used as a
498 string indicating the default level of logging to use if not
499 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
500 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
501 used as before. So, for example, to omit warnings from YAZ logging,
504 cql_transform() now map structure and other attributes before indexes,
505 so that index-specific structures and other attributes can override
506 defaults. So now a combination of mapping specifications such as:
508 index.dc.date = 1=date-modified 4=5
509 does the right thing.
511 cql_transform() now also respects the "always" mapping specification,
512 which establishes an initial set of attributes to be used for all
513 terms except where overridden by more specific attributes associated
514 with the index, relation or modifier.
516 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
517 which mode to use; one of "post", "get" or "soap" (SRW, default).
519 Fixes for yaz_iconv routines: changed trie-based character set conversions
520 to use only non-negative values for bit fields due to Sun's C compiler not
521 supporting negative values.
523 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
524 sequences where not read correctly. Fix by Rustam Usmanov.
526 Updated win/makefile to use options, settings which makes things
527 compile with VS C 2005.
529 --- 2.1.12 2006/02/01
531 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
533 In ZOOM socket code, use select instead of poll on MacOSX.
535 ZOOM-C now support client-side compilation of CQL into RPN that is
536 sent to the server, enabling CQL to be used against all Z39.50
537 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
538 ZOOM_query object, and submit it using ZOOM_connection_search().
539 The CQL-to-RPN translation uses a configuration file, the name of
540 which must be specified in the Connection's "cqlfile" option.
542 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
543 function, which takes as its start-term parameter a ZOOM_query object
544 (which may have had either CQL or RPN set into it).
547 --- 2.1.10 2005/11/29
549 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
550 GFS to support this as well. Backend handler, bend_srw_update, does the
551 update work. Code contributed by Ko van der Sloot.
553 Allow retrieval of Search Result-1 information in ZOOM by the use of
554 options that are attached to a result set. ZOOM documentation updated
557 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
558 UTF-8 conversion. Patch by Raj Patel.
560 Added option -m to GFS to control formatting of timestamps in log file.
562 Added 'exit' as synonym for 'quit' in yaz-client
564 Added support for specifying SRW resultSetId + resultSetIdleTime in a
565 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
566 for the new members. Patch by Ko van der Sloot.
568 Added support for SRU POST. It is supported for content-type
569 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
571 Do not build the separate Multi-threaded (MT) library libyazthread.la.
572 Instead make the library libyaz.la multi-threaded. Threading as a whole
573 can still be disabled by configure option --disable-threads. Previosly,
574 with older GLIBCs there were problems with MT libs under Apache. This
575 has now been fixed a long time ago.
577 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
580 CQL module modified to be case insensitive for relations/indexes/operations.
582 Fixed bug in CQL transform code: incorrect value relationModifieder
585 Added 'show all' command for yaz-client which retrieves all results
588 Added new yaz-client, xmles, which takes a (private) OID and
589 a document to be sent as an extended service request.
591 Describe new yaz-client commands wait_response and set_auto_wait.
593 Increase TCP/IP listener backlog from 3 (which I am guessing was
594 copied from the SunOS manual entry way back when) so SOMAXCONN, so
595 that the socket will queue as many incoming connections as it's able
596 to handle ongoing connections. In other words, it will never now
597 refuse a connection that it would be able to handle merely because
598 it's not got around to accepting() enough of the pending connections
599 yet. This is the behaviour anyway under Linux, where the listen()
600 argument is ignored; but not under BSD and on systems such as
601 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
602 YAZ-based servers should now be uniform across operating systems in
605 yaz-marcdump uses 64-bit file access on some systems. This is enabled
606 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
607 This allows yaz-marcdump to read large MARC batches (>2 GB).
609 Modified all YAZ source files - except the source which is auto-generated
610 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
613 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
614 corresponding to the existing *_setl() function. These allow option
615 values containing arbitrary valuues.
617 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
618 ZOOM_resultset_sort() in new applications. Its behaviour is identical
619 except that it returns an indicator of whether or not the sort
620 criterion was accepted (0 for OK, -1 for invalid).
624 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
625 MARC output rather than returning "new" buffer.
627 yaz-client warns about unknown init options.
629 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
633 Added support for SRW sort in Generic Frontend Server. Patch
634 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
635 sortKeys - or NULL if none is provided.
637 Fixed bug #307: It was impossible to specify indefinite/no timeout
638 for ZOOM_event. Special timeout value -1 now means indefinite timeout
641 Added support for multiple languages and charsets to be specified in
642 ZOOM. Each charset/language is separated by a blank. If negotiation is
643 in effect in init-response, Option
644 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
645 Code based on patch by Vasiliy Osadchuk.
647 Fixed bug #306: infinite recursion that occurred when calling
648 yaz_log_level_init as the first call (before other log level or
651 Fixed bug in scan handling in front end server: if preferred-Position-In-
652 Response was non-present, a NULL pointer referece was performed.
656 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
657 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
658 now defined for all those error codes. So instead of putting 109 in
659 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
660 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
662 Modified the yaz-marcdump utility to skip garbage bytes between MARC
665 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
667 Program yaz-client now exits and produces an error message if multiple
668 Z39.50 servers are specified on the command line (none or one allowed
671 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
676 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
678 Fixed bug #272: Preserve spacing for CCL terms.
682 Added support for virtual hosts and multiple backend servers for
683 the YAZ frontend server. The configution is XML based and
684 support specificition of CQL to RPN mappings and explain information.
685 See section "Virtual Hosts" in the YAZ manual.
687 Extended OPAC display utility. OPAC display utility renders
688 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
689 to supplement yaz_marc_decode_wrbuf.
691 Fixed a bug in MARC decoder that could caused it to crash for some
692 invalid MARC records. More diagnostics and warnings where added in
693 XML output (warnings, etc are stored in comments).
695 --- 2.0.34 2005/02/08
697 Fixes for UNIX domain sockets. Bug #261.
699 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
701 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
702 Added yaz_marc_subfield_str which defines subfield lead string which is
703 used in YAZ_MARC_LINE format. Default string is blank+$. Added
704 yaz_marc_endline_str which defines end of fields string used in
705 YAZ_MARC_LINE format. Default string is newline.
707 Experimental support for MarcXChange. This format can be produced
708 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
709 http://www.bs.dk/standards/MarcXchange.xsd
711 Added yaz-client commands scansize that sets maximum number of
712 entries to be returned by scan.
714 --- 2.0.32 2005/01/11
716 Added support for SRW scan in yaz-client and Generic Frontend Server.
718 * Added whereInList member to SRW Scan Term.
720 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
722 Fixed NMEM system to return aligned blocks on the smallest boundaries
723 that are suitably aligned for all possible types on the particular
724 architecture YAZ is being built for.
726 --- 2.0.30 2005/01/04
728 Fixed numerious warnings that was issued with newer versions of GCC.
730 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
731 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
734 Make YAZ Generic Frontend Server slightly faster.
736 Enhance (and reduce) logging for Generic Frontend Server.
738 Revert YAZ log system so that it flushes every write operation
739 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
741 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
742 instead of LOG_, due to name clash with syslog(3). LOG_ are still
743 present. New applications should define YAZ_USE_NEW_LOG=1 - this
744 will effectively disable old definitions.
746 --- 2.0.28 2004/11/09
748 Added yaz_log_time_format which specifies log format using
751 Added yaz_log_module_level which returns mask for a module. Value
752 is non-zero mask a if module is enabled; zero if disabled.
754 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
755 in include/yaz/cql.h.
757 Fixed bug #176: Dont throw diagnostics on empty SRU args.
759 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
761 Fixed bug #172: RPM builds does not enable SSL.
763 Doxyfile.in part of dist. Doxyfile generated by configure.
765 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
766 are given and the corresponding component does not exist.
768 Extend CCL documentation in YAZ reference. Describe r=r.
770 --- 2.0.26 2004/10/01
772 Fixed MARC->MARCXML conversion to properly deal with
773 fields, subfields, indicators having non-ASCII characters.
775 Fixed MARC->MARCXML conversion so that ASCII control characters
776 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
779 Added YAZ GFS support for conversion from Z39.50 surrogate
780 diagnostics to SRW surrogate diagnostics.
782 Bug fix: YAZ GFS did not return schema in explainResponse.
784 --- 2.0.25 2004/09/30
786 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
787 now converts recordSchema to elementSetName as well as schema URI.
789 Fixed bug in COMSTACK that prevented HTTP request packages from being
792 --- 2.0.24 2004/09/29
794 Added CCL facility r=r "range" which is similar to r=o "ordered" but
795 does not require white-space before and after the dash in a range, e.g.
796 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
799 Fixed a few AC_TRY_LINK configure tests that did not operate properly
800 due to new GCC removing "redundant" code.
802 Added yaz-client commands scanpos and scanstep that sets preferred
803 position and step-size for scan.
805 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
807 Added CCL utility ccl_qual_buf which parses one or more CCL
808 spec lines in a buffer.
810 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
811 of name and value - ignoring empty lines and comments.
813 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
815 Added odr_get_element_path which returns current element path for an
816 ODR handle. This utility is useful in error handling or user-defined
819 Added ODR_PRINT utility odr_set_stream which is is a more generic
820 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
821 to a write function and pointer to close function. The close function - if
822 non-NULL - will be called during odr_destroy.
824 Fixed bug in CCL parser where truncation char was not removed from
825 right side when truncation=both was in effect.
827 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
830 --- 2.0.23 2004/08/11
832 Fix buffer overrun in CQL parser when dealing with proximity (%).
834 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
835 to UTF-8/UCS conversion is now only based on codetables.xml.
837 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
839 --- 2.0.22 2004/08/06
841 Add support for more "commit changes" in ZOOM (uses Extended Services).
843 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
846 Yet another small fix for configure of SSL.
848 --- 2.0.21 2004/05/14
850 Fix SSL libs for configure when --with-openssl=DIR is given.
852 --- 2.0.20 2004/05/10
854 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
856 SSL comstack now uses yaz.pem certificate file on server side
857 by default. Certificate filename can be configured by calling
858 comstack function cs_set_ssl_certificate_file before cs_bind is used.
860 Fix bug regarding multiple calls to ZOOM_connection_connect.
862 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
864 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
865 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
867 ZOOM now allows inspection of X509 peer certificate for verification.
868 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
870 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
871 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
872 as "modular" but it simplifies things.
874 Added cs_get_peer_certificate to that returns peer X509 PEM.
876 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
877 NULL if SSL is unavailable.
879 Documentation about MARC decoding tools.
881 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
883 --- 2.0.19 2004/03/30
885 Rename CHANGELOG to NEWS to follow GNU style packing.
887 Fix bug with missing initialization of member in init_diagnostics.
888 This bug affects threaded version of GFS server.
890 --- 2.0.18 2004/03/20
892 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
895 Ensure zlib.dll is packed with Windows install.
897 --- 2.0.17 2004/03/17
899 Fix encoding of xsd:string to use text instead of CDATA.
901 Fix endless loop in CQL parser with unbalanced ".
903 Use a more compact way to store MARC-8 conversion tables.
905 --- 2.0.16 2004/03/16 Debian only
907 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
910 Update CQL parser to use new CQL 1.1 modifiers for booleans and
915 --- 2.0.15 2004/03/01
917 Another fix for decoding of XML packed records.
919 --- 2.0.14 2004/02/25
921 Fixes for Chunked encoding. White space not ignored after length spec.
923 Update NS and use default NS for SRW diagnostic elements.
925 --- 2.0.13 2004/02/23
927 Implement ZOOM_resultset_cache_reset which resets record cache.
929 Implement ZOOM_resultset_sort which sorts a result set.
931 Implement chunked HTTP transfer.
933 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
935 --- 2.0.12 2004/02/16
937 Added member 'schema' to bend_explain_rr structure so that backend
938 can specify explain record identifier. Defaults to Zeerex 2.0.
940 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
942 --- 2.0.11 2004/02/16
944 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
947 Added init command for yaz-client which sends "extra" init request.
949 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
950 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
952 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
954 Make ZOOM error code for "invalid query".
956 Fixed compilation for SSL which wasn't properly enabled for all platforms.
958 --- 2.0.10 2004/02/05
960 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
963 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
965 Added option -p <file> to make Generic Frontend Server to write PID file.
967 Added option -D to put Generic Frontend Server in background on its own.
969 Make ZOOM C recognize option "password". If unset, "pass" is used
970 (for backwards compatibility).
972 Fixed a bug in Generic Frontend Server that could make it crash if a
973 client sets characterSetNegotation bit, but didn't pass negotiation stuff
976 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
977 Must be issued before open, in order to be in effect.
979 --- 2.0.9-6 2004/01/12 Debian/Windows
981 Make the SRU server more picky WRT unknown params, etc.
983 Bug fix: ZOOM scan response didn't return displayTerm - when present.
985 New YAZ client command, options, that sets Z39.50 options.
987 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
988 options from a string of tokens (one token for each option bit).
990 Update SRW diagnostic code messages.
992 --- 2.0.9-5 2004/01/07 Debian/Windows
994 Handle user defined stylesheet for SRW/SRU.
996 --- 2.0.9-4 2004/01/06 Debian/Windows
998 Fix bug in decoding of Content-Length.
1000 --- 2.0.9-3 2004/01/06 Debian/Windows
1002 Fix a bug with decoding of XML packed records.
1004 --- 2.0.9-2 2004/01/05 Debian only
1006 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1008 Fix bug in SRW/SRU diagnostics decoding.
1010 --- 2.0.9 2004/01/05
1012 Fixed bug in Generic Frontend Server which could drop records exceeding
1013 preferred message size. Reported and fixed by Irina Dijour.
1015 Fixed calculation of package size for structured records in Generic
1016 Frontend Server. Reported and fixed by Irina Dijour.
1018 Fixed namespace for SRW/SRU diagnostics.
1020 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1022 --- 2.0.8 2003/12/22
1024 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1025 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1028 CQL changes to reflect recent changes to the specification:
1029 * Documentation talks about context sets instead of index sets.
1030 * Documentation talks about indexes instead of qualifiers.
1031 * The CQL-to-PQF transformer's configuration file now uses
1032 "index.set.name = <attributes>" instead of the old form
1033 "qualifier.set.name = <attributes>". (Both forms are still
1034 understood but the latter is deprecated.)
1035 * CQL terms with no explicit index specified are now interpreted as
1036 cql.serverChoice instead of srw.serverChoice (which of course
1037 behaves exactly the same.)
1039 --- 2.0.7 2003/12/16
1041 MARC conversion can now generate ISO2709 output in another
1042 character set. yaz-marcdump uses this facility if you invoke it
1045 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1046 functions from there can be used from C++.
1048 --- 2.0.6 2003/12/04
1050 Frontend server now transfers memory from decoded packages to stream
1053 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1054 references to show up.
1056 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1057 the ZOOM Abstract API. The older names for the same options are still
1058 also supported for the benefit of old applications.
1060 ZOOM-C supports "implementationId" and "implementationVersion" options
1061 to go along with "implementationName". These allow the user code to
1062 specify identification strings to be sent to servers.
1063 Add OID for the new ExtLite attribute set.
1065 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1066 as requested/supplid by Ere Maijala <ere@atp.fi>
1068 For generic frontend server, reverse the order of
1069 "toolkit-supplied / application-supplied" strings sent as implementationId,
1070 Name and Version. Also, remove the spaces around the slash. This brings
1071 the GFS in line with the behaviour of ZOOM-C on the client side.
1073 Add function ZOOM_scanset_display_term.
1075 yaz-client shows scan displayTerm if present.
1077 Utility yaz-iconv is now installed by default along with the man page
1080 Extend configure check for OpenSSL to use pkg-config where available (such
1083 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1084 server to specify uid/gid/mask for socket using the format
1085 unix:[user=uid,][group=gid,][umask=mask,]file=path
1086 If file= is omitted the existing format is assumed, e.g.
1088 in which case the mask is 0666 (rw for everybody).
1090 Major restructure of YAZ source. All source in libyaz is in src directory.
1091 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1092 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1094 Added man page for utility yaz-marcdump (used to be called marcdump).
1095 yaz-marcdump is installed by 'make install'.
1097 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1098 of incoming package failed.
1100 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1102 Change prototype of odr_perror: add const to message string.
1104 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1106 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1107 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1108 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1109 DNS lookup. There should not be any compatibility problems with this
1110 assuming that blocking=1 or 0 is used.
1112 Fix bad reference in UNIX comstack in function cs_addrstr.
1114 Fix for compilation on AIX.
1116 The generic front-end server (server/seshigh.c) now supports returning
1117 Init diagnostics to the client in User-information-field, in
1118 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1121 --- 2.0.4 2003/09/04
1123 Allow any CQL relation (not just all,any,exact,scr).
1125 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1126 that features the same UI.
1128 Implemented command update0 in YAZ client which is equivalent to
1129 update but uses old of Ext Update ASN.1.
1131 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1132 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1133 Previously no OID was used for this info.
1135 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1136 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1137 returns 'malformed search term' otherwise.
1139 SortResponse member resultCount now set to NULL in sort handler of
1142 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1145 Add three new utility functions for translating OIDs between various
1146 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1147 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1148 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1149 char *oid_to_dotstring(const int *oid, char *oidbuf);
1150 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1152 Reverted modifications for ES Update definition for z_IU0Update
1153 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1154 is back to YAZ 2.0.2.
1156 String value attributes for CCL parser.
1158 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1159 which their FirstSearch server returns in Init responses, sometimes
1160 carrying useful diagnostic information when Init fails. This has the
1161 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1162 "z39.50/oclcui.asn", where its definition is somewhat different from
1163 what OCLC document on their web-site, as required to interoperate with
1166 Support for anonymous authentication in yaz-client. Use the command
1169 * Fix the OID of the Index Data-local "admin" Extended Service from
1170 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1171 the 1000, which indicates a locally-defined OID, was a mistake.
1173 --- 2.0.3 2003/06/20
1175 Fix CCL directive @case handling so that it affects string match for
1176 both CCL keywords and qualifiers.
1178 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1179 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1180 Decoder has been updated with ASN.1 changes as listed in
1181 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1182 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1183 z_IUUpdate, remains unchanged.
1185 ZOOM_record_get may now return a record in a specific character set.
1186 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1187 "from" is the character set of record as returned by target. "to" is
1188 the character set to be returned. If omitted, "to" is UTF-8.
1190 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1192 New ODR utility, odr_getelement, which returns name of element for
1193 which encoding/decoding failed.
1195 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1196 in cases where a required element was omitted.
1198 Bug fix: some MARC8 sequences were not converted.
1200 New ZOOM option "step" which specifies number of records to be
1201 retrieved in one chunk. Used in conjunction with "start" and "count".
1203 SRW support for yaz-client. Use scheme http: to use it, e.g.
1206 yaz-client no longer does (un)intelligent character set conversions
1207 by default. Can be enabled with charset and marc_charset commands.
1209 xmalloc trace fix for 64-bit systems such as DEC alpha.
1211 Solaris 2.6 compile fix.
1213 New function, cql_strerror() translates SRW error codes, as returned
1214 by cql_transform_error(), into human-readable English strings. Used
1215 in yaz-client diagnostics when appropriate.
1217 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1218 converts it into a type-1 query which is sent to the server. This
1219 makes CQL available for use with all Z-servers, as opposed to the tiny
1220 minority that can handle CQL queries themselves.
1222 --- 2.0.2 2003/04/28
1224 New Debian package layout similar to the Redhat Package layout.
1226 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1227 and search result respectively.
1229 --- 2.0.1 2003/04/25
1231 Redhat package is now several packages: libyaz (runtime libraries),
1232 libyaz-devel (development and documentation, and yaz (utility programs).
1233 Package spec file by Morten Bøgeskov.
1235 New member 'schema' in struct bend_fetch_rr which the name of requested
1236 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1237 handler MAY set this to reflect the schema of the returned record.
1239 New member 'display_term' in struct scan_entry. GFS now sets member entries
1240 and allocates scan entries to be filled by user scan handler. In previous
1241 version, entries member was allocated by the scan handler. That still works,
1242 but the GFS will ignore member display_term - assuming it was NOT set by
1243 the handler. The fact that the GFS now allocates the entries both allows
1244 for new members and makes a scan handler easier to write.
1246 Fix CQL lex buffer overflow.
1248 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1249 SRU default recordPacking is string.
1251 SRU protocol support for frontend server.
1253 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1255 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1257 Added scan for the ZOOM shell (zoomsh).
1261 * String Identifers for Schemas (Amendment 5).
1262 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1263 Old definition for schema
1264 Odr_oid *schema; /* OPT */
1269 Z_InternationalString *uri;
1270 #define Z_Schema_oid 1
1271 #define Z_Schema_uri 2
1274 * resultCount parameter to Sort Response (Amendment 1).
1275 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1277 Support for SRW 1.0 over HTTP. This is an optional feature and
1278 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1281 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1282 on the same port. SRW SearchRetrieveRequests are mapped
1283 to bend_init,bend_search,bend_fetch,bend_close.
1285 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1287 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1288 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1290 ZOOM connections are SRW based if schem http is used for hostname
1291 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1292 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1294 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1295 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1296 distance=n, order=true/false, relation=le, prox unit=word. If
1297 n is omitted, distance 1 is used.
1299 Fixed problem with C compiler include path in wrong order.
1301 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1302 on Solaris. Patch from Ko van der Sloot.
1304 New MARC decode API. All new functions operate on a yaz_marc_t
1305 handle. The most important new functions are: yaz_marc_create,
1306 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1307 decode and destroy respectively. Decoder can produce formats
1308 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1309 include/yaz/marcdisp.h.
1311 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1312 to UTF-8, UCS-32, wchar_t or Latin-1.
1314 * Prototypes for yaz_iconv_-functions moved to separate header
1315 include/yaz/yaz-iconv.h.
1317 Make a few private functions 'static' in unix.c. This prevents
1318 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1320 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1321 are set when Init Response is received.
1323 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1324 but returns diagnostic set as well.
1326 New function yaz_strerror which is a portable wrapper for
1327 strerror/strerror_r/GetLastMessage.
1329 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1330 is returned for MARC. If type is "oai", then OAI MARC is returned.
1332 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1335 --- 1.9.2 2002/11/26
1337 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1339 Fix bad race conditions on SIGTERM and terminate gracefully in
1342 Move retrieval (data1) module to Zebra since nobody seems to be
1345 Add GRS-1 render for ZOOM using same format as yaz-client.
1347 --- 1.9.1 2002/10/05
1349 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1351 Fix broken ESpec handling in data1 module.
1353 SGML reader parses comments and makes them part of the data1 tree.
1355 Added several type casts so that YAZ compiles as C++ code.
1357 ZOOM didn't handle PDU encoding failures properly.
1359 Added more Bib-1 diagnostics (approved extensions).
1361 GNU configure: better check for iconv.
1363 More portable use of accept, getpeername. Check for socklen_t. Use
1364 int/size_t if socklen_t is not defined.
1368 PQF parser rejects bad queries - including those with extra
1369 characters in them. PQF parser used to silently ignore that.
1370 Cleaner API for PQF added, which allows you to get detailed
1371 error information for bad queries (see yaz/pquery.h).
1373 Fixed bug in ZOOM_record_get for type "database".
1375 Implemented mini iconv library supporting conversions between
1376 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1378 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1380 --- 1.8.9 2002/08/20
1382 Fixed ZOOM C record cache so that preferredRecordSyntax and
1383 elementSetName is used to check for already fetched records.
1385 --- 1.8.8 2002/08/02
1387 Added three members in bend_initrequest structure to facilitate
1388 character set negotiation.
1390 Fixed a bug in frontend server that could cause indefinite
1391 loops under rare conditions.
1393 Revised character set utilities (charneg.h) so that encoding
1394 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1396 For PQF, directive @term <type> sets term type for Scan/Search.
1397 Here <type> is general, string, numeric, null. The term type
1398 is inherited - just like @attr.
1400 New call odr_set_charset that sets character set conversion for
1401 international-strings on a ODR stream. Prototype is:
1402 int odr_set_charset(ODR o, const char *to, const char *from);
1403 The InternationalString is still represented as C string in YAZ
1404 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1405 won't). On the protocol level, you can use any encoding.
1407 Support for UNIX sockets in ZOOM.
1409 Solaris recv sometimes returns errno == ENOENT. It is treated as
1410 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1412 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1413 both client and server. Code by Morten Bøgeskov.
1415 --- 1.8.7 2002/05/22
1417 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1418 that they can be used directly from Visual Basic. You must recompile
1419 your windows APP if you're using ZOOM.
1421 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1422 Commands "lang" and "charset" sets language and character set respectively.
1423 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1424 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1426 Attributes from multiple CCL fields may be OR'ed rather than merged
1427 using directive "@field or". Fields are still merged by default -
1428 equivalent to "@field merge".
1430 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1433 Fixed bug in zget for parameter ExtendedServicesResponse.
1437 --- 1.8.6 2002/03/25
1439 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1441 Client displays USR.1:SearchResult-1 (hits per term).
1443 Additional Search Info for search in Generic Frontend Server.
1445 Fixed CCL parsing of "field=s".
1447 WIN32 installer - using the excellent NSIS software from nullsoft.
1449 Fixed CCL parsing of "field = - <number>".
1451 Added function yaz_marc_decode that decodes MARC for line mode
1452 display or XML (similar to that used by JZKit).
1454 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1455 Z39.50. But ISO/ILL was, however.
1457 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1458 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1460 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1461 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1463 --- 1.8.5 2002/02/03
1465 New YAZ client features: Command completion and new commands:
1466 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1467 Code provided by Jacob Poulsen.
1469 New call oid_trav, that visits all registered OIDs via callback.
1471 Function ZOOM_record_get now returns const char pointer rather than
1472 void pointer. It saves a lot of type casts.
1474 For YAZ client, command "auth" now allows you to set authentication
1475 in IdPass style. It is enabled when three tokens are given - order
1476 is user, group and password.
1478 Fix memory leaks in MARC record handling for ZOOM.
1480 New option for YAZ client, -k <kilobytes> that sets
1481 maximum record size. Similar to -k option for generic frontend
1482 server and yaz-ztest.
1484 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1486 Prefix query parser reports "fail" when bad attribute set is given.
1488 Fix in MARC decoder. Proximity logging. Fix for attribute set
1489 in scan handler for server. Patches by Shigeru Ishida.
1491 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1494 Configure option --with-openssl=<dir> now works when a directory is
1495 specified. Patch provided by Morten Bøgeskov.
1497 New option for YAZ client, -u <auth>, that sets authentication.
1499 ZOOM fix: error information was sometimes "missing", since error
1500 was cleared/reset too when it shouldn't.
1502 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1504 --- 1.8.4 2002/01/04
1506 Scan for ZOOM API. New object ZOOM_scanset. New functions
1507 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1508 ZOOM_scanset_destroy.
1510 New ZOOM function, ZOOM_connection_last_event, that returns type
1511 of last event (such as "receive data", "send data", "apdu received",
1514 New ZOOM option, schema, that specifies schema for retrieval.
1516 New CCL feature. Qualifiers can be aliases for one or more
1517 other qualifiers (if more than one is given, OR is used).
1519 ZOOM uses named result sets if target supports it.
1521 Two new YAZ client commands: . (dot, which sources a script of YAZ
1522 client commands), and ! (to execute shell command.). Implemented
1525 Working on Debian packages.
1527 --- 1.8.3 2001/11/19
1529 YAZ client enables named result sets only if target supports it.
1531 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1533 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1534 with key="host" to get same result.
1536 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1537 Function Z3950_resultset_record(s) returns references to records
1538 "owned" by resultset. To become owner use Z3950_record_clone.
1540 Function z_ext_record handles Extended Services. Thanks to
1543 --- 1.8.2 2001/11/12
1545 CCL Parser fix: ignore token comma when dealing with and-lists.
1547 Documentation updates for COMSTACK.
1549 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1550 Changed prototype Z3950_records. For some functions, int parameters
1551 were changed to size_t.
1553 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1556 New MARC decode/display function, marc_display_exl, which properly rejects
1557 non-ISO2709 records. YAZ client uses it.
1559 --- 1.8.1 2001/10/29
1561 Fix bug: local attribute set wasn't set correctly in PQF strings.
1565 * Old Z39.50 codecs no longer supported.
1567 Added ZOOM C binding. See http://zoom.z3950.org/
1569 Renamed states for COMSTACKs to avoid confusion with events.
1571 Implemented cs_look and proper cs_rcvconnect.
1573 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1575 Configure detects POSIX threads on OpenBSD.
1577 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1578 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1580 When error is returned from present handler, non-surrogate diagnostic
1581 is returned in present response (and fetch handler is no longer called).
1583 * Minor adjustments to pquery parser (PQF). Token characters may be
1584 escaped by using backslash (C-style).
1586 PQF parser allows string attribute values to be specified. For @attr,
1587 non-numeric characters after the equal-sign are treated as strings
1588 (e.g. @attr 9=title).
1590 CCL trunction character may be defined (@truncation in file)
1592 * function zget_ExtendedServicesRequest sets waitAction to
1593 waitIfPossible (was wait).
1595 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1598 CCL operator names may be set in field definition files (CCL_bibset).
1599 See ccl/bib1 for an example.
1601 Fixes in ASN.1 compiler for C++ compatibility.
1603 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1604 and "op_or" to avoid conflict with C++.
1606 Fixed problem with GNU readline detection on Redhat 7.0.
1608 Added step-size for Scan backend handler.
1610 Fixed bug that made the frontend server crash when no attribute
1611 set was specified for scan.
1613 Front-end server automatically switches to original working directory
1614 when installed as an NT service. Previously -w had to be specified to
1617 Added extended attributes for retrieval module (data1), so that data1
1618 records carry d1_readXML/SGML attributes. d1_read also supports
1619 null-data rules ( <tag/>)
1621 On UNIX when POSIX threads are available, a separate library libyazthread
1622 is created. Programmers should link with that library and the yaz library
1623 when using threads. The reason for the split was that some applications
1624 on Linux, such as Apache, doesn't work well when using shared objects that
1627 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1628 (or any frontend server) in SSL mode by specifying ssl: followed by
1629 address. Only tested on UNIX.
1631 Added feature for CCL module. Virtual structure s=al or s=ol generates
1632 and-list and or-list respectively instead of phrase search.
1636 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1637 log_mask_str. This was done to avoid name conflicts with other libraries
1638 (such as other PHP extensions).
1640 Added raw OID member for preferred record syntax (request_format_raw)
1641 and returned record syntax (output_format_raw) for backend fetch method.
1643 Config file yaz-config now accepts options so that it returns specific
1644 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1646 Shared library support for UNIX using GNU libtool.
1648 * Modified backend interface. Request/Response struct's replaced by
1649 one read/write C struct. For example bend_fetchrequest and
1650 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1651 Every handler - even search has to be registered in bend_init
1652 handler. This means that the YAZ library no longer refers to
1653 external functions and it makes it possible to make the whole
1654 thing a single DLL/SO.
1656 Added Segment handler for backend server.
1658 Added Zmbol/Zebra administrative functions to YAZ client.
1660 Threaded frontend server on UNIX (when POSIX Threads are available).
1661 Starting the server with option -T enables multi-threading.
1665 Added configure option --enable-comp/disable-comp to control use
1666 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1667 located in sub directory asn.
1669 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1670 in ${exec_prefix}/bin along with the other programs yaz-client and
1673 GNU automake used to maintain makefiles.
1675 Added several OID's.
1677 Changed retrieval module so that we can load records with no abstract
1678 syntax defined. Tagpaths in these records are fully composed of string
1681 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1685 On UNIX, the generated makefile now supports a proper 'make install'.
1686 The prefix can be set via GNU configure to set the install location
1687 (default is /usr/local).
1689 * YAZ programs client and ztest were renamed to yaz-client and
1690 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1691 locations, such as /usr/bin,/usr/local/bin,etc.
1693 * YAZ Header files were moved from include to include/yaz. YAZ Header
1694 files are referred to as include <yaz/log.h> rather than <log.h>.
1695 The YAZ include path (-I ..) is therefore the same as before. Programmers
1696 should update their #include statements or use -Ipath/include/yaz
1697 instead. The main motivation for doing this change is that YAZ header files
1698 can be installed in "standard" locations /usr/include,/usr/local/include
1699 without introducing conflicts, since ALL YAZ header files are stored
1700 in subdirectory yaz (under /usr/include for example).
1702 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1703 rather than project/workspace files. We switched because project files
1704 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1707 Changed name of logging function, logf, to yaz_log, to prevent name
1708 clash with some math-log functions. The YAZ header log.h defines logf
1709 to yaz_log (#define) so there should be no incompatibilities by this
1712 Added bend_start/bend_stop handlers for server. These handler are
1713 called on start/stop of server. For windows they are called whenever
1714 a service is started/stopped.
1716 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1717 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1718 in util/yc.tcl. The auto-generated C code structures are, in a few
1719 cases, incompatible with the old decoders. There are differences in the
1720 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1721 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1722 The preprocessor variable ASN_COMPILED is defined when the compiled
1723 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1724 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1725 wish to use the old encoders/decoders you can specify --disable-yc
1728 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1729 version so that it supports both new - and old version of DB Update
1731 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1732 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1733 change. The name parameter can be set to 0 in which no name is specified
1734 for the construction. The macros odr_implicit and odr_explicit sets name
1735 parameter to zero for the construction involved. New macros
1736 odr_implicit_tag and odr_explicit_tag are similar to the others,
1737 except that a name parameter is added. For programmers' that don't use
1738 ODR they probably only need to change the call to z_APDU and z_External.
1740 Added access control facility by interfacing the TCP wrapper library.
1741 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1742 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1743 name of the daemon and enables the access control as specified in
1744 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1746 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1747 den Dool <H.M.vdnDool@kub.nl>.
1749 Added reference ID parameter to most functions in server API - refer
1750 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1752 Changed name of ccl library to libccl.a (was ccl.a).
1754 Fixed bug in decoder for Explain (Category TargetInfo).
1756 Added support for GNU readline in client. Thanks to Jacob Poulsen
1757 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1759 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1760 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1761 IMPLEMENTATION! This change was made to the development version before
1762 the ZIG decided to retract the amendment. If any users MUST be
1763 compatible with the original Update definition, PLEASE CONTACT US, and
1764 we will include a separate definition corresponding to the old Update
1765 ES. Note that because of the change to the ASN.1 of the
1766 TaskPackageRecordStructure we cannot define a single structure that
1767 will support both versions.
1769 * Added const modifier to buffer parameter for some ODR/BER encoding
1770 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1771 completeWAIS, odr_dumpBER.
1773 Fixed bug in client.c which caused a crash when a scanResponse didn't
1774 contain positionOfTerm.
1776 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1777 * will cause an error in a client if a non-YAZ target sends both a
1778 * list of Scan entries and non-surrogate diagnostics.
1780 Retrieval module enhancements. Tag sets may be typed in the reference
1781 to it. From the .abs-file the "tagset" directive takes a third optional
1782 integer type for the tag set referenced. From a .tag-file the "include"
1783 directive takes a third optional type as well. The old "type" directive
1784 in the tag set itself is still recognized but acts as the default type
1787 Backend interface change. Individual Scan terms returned from bend_scan
1788 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1789 in include/backend.h.
1791 Retrieval module enhancements. Multiple tag sets and attribute sets may
1792 be specified in abstract syntax specs. Revised the error/warning for
1793 logging messages reported by the retrieval module when reading the
1796 Object Identifier system (oid_..) changed. The API is backwards
1797 compatible but the oid-routines now allocates new OID's when needed.
1798 Raw OID's may be specified in oid_getvalbyname.
1800 YAZ now uses GNU configure to generate Makefile(s).
1802 * Minor changes in some of the member names of DeleteResultSetRequest and
1803 DeleteResultSetResponse. See include/proto.h.
1805 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1806 and added member 'languages' in TargetInfo (which was missing).
1808 Changed the way attribute sets are handled in the retrieval
1809 module. These are now cached, just like the abstract syntaxes
1812 Changed YAZ so that it links with compiled ASN.1.
1814 Added Explain-schema definitions and mapping routines. The following
1815 Explain categories have been implemented: AttributeDetails,
1816 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1818 Fixed minor bug in Windows version of Server Library.
1820 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1822 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1824 Added EXTERNAL: UNIverse Resource Report (non-standard).
1826 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1827 ENUMERATED and SET OF.
1829 * Added 'const' to some of the char pointer arguments for the
1830 functions, data1_read_node, data1_getelementbytagname,
1831 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1834 Fixed bug in data1_insert_taggeddata - the last_child member of
1835 parent wasn't initialised.
1837 * Changed data1_read_record and data1_read_node so that the supplied
1838 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1839 doesn't refer to any parts of the "SGML"-buffer.
1841 Fixed bug in server library (Windows version of statserv_remove).
1843 * Changed code so that it compiles as C++. The type definition
1844 of Odr_fun which is a member of Odr_arm was changed. The result is,
1845 that an explicit typecast is needed for the fun pointer when
1846 using Odr_arm - as in:
1847 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1849 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1851 Implemented the new structured date and time definition as approved
1852 by the ZIG. Added schemaId element to the specificTag in Espec-1
1853 (also approved at the last ZIG). Thanks to RVDM.
1855 Added some Object identifiers (RVDM).
1857 Changed the Update Extended Service (RVDM).
1859 Added command "refid" to client which specifies referenceId for
1860 the following requests.
1862 Implemented extended service handling for server. See ztest.c
1863 for an example as well as backend.h. New handlers are registerd
1864 in the Init handler.
1866 * Changed interface for sort in server.
1868 Added new members to statserv_options_block. It allows a server
1869 to read options from another source than just the command line. Thanks
1870 to Charles Woodfield.
1872 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1873 renamed to zboolean. Some C++ compilers complained about the name.
1875 Minor changes to gils.abs. Added index 's' (sort) on title
1876 and date/time-last-modified.
1878 --- 1.4pl2 1998/1/30
1880 Fixed bug in server library regarding inetd mode (-i). This bug
1881 was introduced by release 1.4.
1883 --- 1.4pl1 1998/1/29
1885 Added sort facility in client and backend server interface.
1887 Fixed problem with dependencies in Makefile(s).
1889 Fixed bugs for encoders/decoders of extended services and
1892 Implemented sub-tree feature for schemas. Sub-trees are
1893 referenced in *.abs-files. See explain.abs for an example
1894 of the use of this feature.
1896 Modified bib1.att; local attributes for ANY didn't include
1897 ANY itself (only affects use of the retrieval module).
1899 Fixed bug in plain SGML reader in function data1_read_node:
1900 tags with prefix "var" was incorrectly interpreted as variants.
1902 Added feature "sub-schemas" to enable references to - and definitions
1903 of - group of elements.
1905 * Removed member parent from type data1_element (in data1.h).
1907 Implemented function odr_nullval() that returns the value of
1910 * Removed member num_children from data1_node (in data1.h).
1912 Made NT service interface part of the server library. The
1913 function statserv_main uses the NT service when required and
1914 calls the statserv_start / statserv_close routines.
1916 Routine zget_SearchRequest and zget_PresentRequest fills
1917 resultSetName/Id member with "default" instead of "Default".
1919 Fixed memory leak in server. Request queue member wasn't freed.
1921 Fixed nmem_exit so that memory is freed.
1925 Revised the CCL parser utility to be thread safe.
1927 Added function, oid_ent_to_oid, to replace the function
1928 oid_getoidbyent, which is not thread safe.
1930 * Added nmem_init and nmem_exit to initialize and release
1931 NMEM resources. Function nmem_init should be called once in the
1932 initial thread before NMEM/ODR is used. statserv.c and client.c
1933 have been changed accordingly. The change was necessary to make
1934 NMEM thread safe. The NMEM memory pool is shared amongst threads
1935 in a process. Unix-based applications will still work fine without
1938 Added NT Services interface for the the Z39.50 (statserv) Server.
1939 Refer to the ztest.c source on the usage.
1941 Windows 95/NT port using MSVC5.0. Project files are included in the
1944 * Defined new 'global' handle for the retrieval (data1) system. The
1945 new handled, data1_handle, describes the state of the data1 system.
1946 This handle is passed as first argument to virtually all
1947 data1 related routines. The functions data1_create and data1_destroy
1948 creates and destroys a data1 handle respectively.
1950 Added ODR encode stream member to all backend request structures
1951 init, search, scan etc. This stream should be used to allocate all
1952 memory used for the response when thread safe operation is needed.
1954 Changed the comstack utility, cs_addstr, to be thread safe. The
1955 returned hostname string returned by the function is now part the
1958 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1959 function. The cs_straddr takes a COMSTACK handle as argument, so this
1960 function must be used after cs_create and before bind/connect.
1961 This function is thread safe.
1963 Moved test server to 'ztest' directory - generic server code still
1964 in 'server' directory.
1966 Made prefix query (pquery.c) utility thread safe.
1968 Added new function modifier YAZ_EXPORT to 'export' public DLL
1969 functions when using windows (see include/yconfig.h).
1971 Added definitions to the OID database (util/oid.c) (RVDM).
1973 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1975 Added call to ccl_rpn_delete in client program.
1977 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1978 release of RPN structure.
1980 Added support for C++, headers uses extern "C" for public definitions.
1981 With input from RVDM.
1983 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1984 Thanks to Ronald van der Meer (RVDM).
1986 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1988 Added support for private extensions to the OID database
1989 (oid_setprivateoids()). Thanks to RVDM.
1991 Added optional, physical ANY (key replication)
1993 Fixed null-reference problem in GRS-1 output filter.
1995 Proximity operator added to Prefix Query Format (PQF).
1997 In test client command "base" accepts multiple databases.
1999 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2003 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2005 Smallish bug-fixes in the new encoders/decoders (explain).
2007 Bug fixed in DeleteRequest.
2009 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2011 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2013 Added SOIF syntax (using private OID for now) to retrieval module and client.
2015 Added Update extended service.
2017 Added SearchResult-1 additional info structure.
2019 Added optional CCL (ISO8777) interpreter as separate module. Available
2022 --- 1.2 1996/6/10 (1st anniversary release)
2024 Added Summary record syntax. Lightly tested.
2026 Added OPAC record syntax. Untested.
2028 Added ResourceReport service encoders/decoders. Untested.
2030 Fixed bug in z_Unit - wrong tagging on unitSystem.
2032 Fixed bug in the DiagRecs decoder.
2034 Added options for max PDU size and session timeout to frontend-server.
2036 Added documentation of query-language parsers and other supporting utilities.
2038 [frontend-server] Added Attribute set to the bend_scanrequest API.
2040 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2041 surrogate diagnostics were generated.
2043 [retrieval] Allow multiple local values for attribute.
2045 [retrieval] Allow multiple attributes per element in .abs files. index type.
2047 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2049 --- 1.1pl2 1996/4/10
2051 Minor changes, mostly specific to Zebra's requirements (retrieval)
2055 Repaired bug in frontend server when running multiple listening
2056 endpoints in dynamic mode.
2058 z_External() now won't break if a known, ASN.1 value comes encapsulated
2059 in an octet-string. The value will pass through unmodified in an Odr_oct.
2061 Added a bit of code to the demo client to decode & display
2062 ASN.1-structured records represented in the octet-aligned branch of
2063 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2065 Added z_ext_getentbyref() to the ASN module. Doc updated.
2067 * Completed the SCAN definition in the ASN module. This may break SCAN
2068 code based on older YAZ-versions at compile-time. The fix is easy -
2071 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2072 under the SCAN definition. Remember to initialize this, server-people.
2074 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2075 that this does not extend to ODR and ASN.
2077 Comstack allows insertion of established socket (primarily for
2078 inetd-operation of servers). Doc updated.
2080 Front-end server can now start from the inetd in TCP mode. Doc
2083 --- 1.0pl4 1996/1/24
2087 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2088 the rank and record number.
2090 Adjustments to the frontend server.
2092 Fixed diagnostic BER dumper. It ignored the file argument.
2096 Various changes to retrieval module.
2098 Changed the union discriminators of the protocol files from enums to
2099 ints paired with #defines.
2101 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2104 *Changed operator in the RPN structure to 'roperator', again to avoid a
2107 Fixed problems in Explain decoders/encoders.
2109 --- 1.0pl2 1995/12/6
2111 Memory bug in log module fixed.
2113 --- 1.0pl1 1995/12/5
2115 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2117 Bug in Explain DatabaseInfo module fixed.
2119 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2123 The shift to v1.0 signals that we now consider the *core* functionality
2124 of YAZ reasonably stable (the core being more or less equivalent to
2125 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2126 tested (Explain not at all - though that will happen soonish).
2128 Minor changes to code to support Windows port.
2130 Various minor changes after we're getting to use GRS-1 & co. more.
2132 Added Espec-1 format.
2134 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2135 of the protocol and it cannot be selected when encoding (maps into 'string'
2136 when decoding). Needed to talk to some servers.
2138 Demo client can request simple element set names.
2140 Added Diagnostic Format encoders/decoders.
2142 Added simple Close handling to frontend server (no hooks for resource
2143 reporting yet), and demonstration client.
2145 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2147 --- 1.0b3 1995/08/24
2149 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2150 handled incorrectly when records were requested in the searchResponse. This
2151 will only affect you if you use the frontend-server.
2153 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2154 Test-client will ask for and print GRS1. Ztest will return dummy records
2157 Added Explain encoders/decoders to the service-level API. Untested.
2159 Added Extended Services: Item Order encoders and decoders to the Service-
2160 level API. Untested. We could use a recent copy of the pertinent bits
2161 of the ILL protocol to add those bits.
2163 Added diagnostic format 1 encoders/decoders to the service-level API.
2166 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2167 odr_cons.c, which causes a more correct output.
2169 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2170 was always set to 0 when no records were requested in the searchRequest.
2172 * Added better external-handling. This shouldn't harm old code that
2173 *encodes* externals. It can break code that looks for a
2174 'single-ASN1-type' representation, since those types that are known
2175 are now decoded immediately. Look at the SUTRS sample code in
2176 seshigh.c and client.c. Documentation updated.
2178 Handling of structured records in bend_fetchresponse. Length -1 marks
2179 structured record, type is deduced from format field.
2181 --- 1.0b2 1995/06/27
2182 Fairly quick maintenance release to add SUTRS support.
2184 Fixed handling of SUTRS records in the demonstration client.
2186 * Added format field to the bend_fetchrequest and bend_fetchresponce
2187 structures of the backend API (frontend server). When the record is
2188 returned, the value of the format field is mapped to an OID. The
2189 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2190 of the record. The special value VAL_NONE in the bend_request means
2191 that no specific format was requested by the client. Documentation
2192 updated accordingly. Test server (ztest) will return a fixed dummy
2193 SUTRS record if your client requests SUTRS.
2195 Documentation updated accordingly.
2197 You can now set external libraries and RANLIB support in the top-level
2201 First public release.
