3 Fixed bad memory reference in ZOOM_record - cuased by member not being
4 initialized. This was a problem only in YAZ 3.0.12.
6 Fixed bug in conversion from MARC to XML: Non-XML characters in control
7 fields were not removed.
9 Changed the way C code is generated from codetables.xml. Made a MARC-8
10 conversion trie for each characterSet section rather than codeTable.
11 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
12 of codetables.xml from Larry Dixson, LOC. Bug #1464.
16 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
17 from ZOOM_record_error).
19 ZOOM C function ZOOM_record_get returns record schema for type="schema".
21 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
23 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
25 Better SRW-to-Bib-1 diagnostic mapping.
27 ZOOM C and yaz-client announces SRU version 1.2 by default.
29 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
32 Fixed in yaz_sru_decode to allow other version than 1.1.
36 Added support for SRU scan for ZOOM.
38 Added support for the use of the older versions or Extended Service
39 Update in ZOOM. To faciliate this, an option "updateVersion" may be
40 set to the version , 1=first, 2=second, 3=third. The third version is
41 what ZOOM C has used so far. And that, obviously, is the default.
43 Added support for CCL queries in Z39.50 queries sent to the GFS (and
44 therefore in Zebra and in SimpleServer-based applications). The new
45 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
46 qualifier file used to transform incoming CCL queries into Type-1 RPN,
47 which is passed into the back-end search callback function.
49 Added support for HTTP Basic authentication in clients: the SRU/W
50 codec encodes the username/password elements of the PDU structure
51 appropriately, and these may be set using the "user" and "password"
52 options in ZOOM-C applications (the same options that are used for
53 Z39.50 authentication).
57 Fixed bug #1208: SSL appears to be broken in ZOOM.
59 Fixed bug #1206: Libxml2 include path weirdness.
61 Added oid_name_to_dotstring.
63 Allow elementSetName to be specified for ZOOM C record update.
65 Allow waitAction to be specified for ZOOM C based for Extended Services.
67 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
68 syntax OID. Bug introduced in YAZ 3 series.
70 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
74 Fixed bug #1157: yaz-client does not read .yazclientrc from current
75 directory. yaz-client now reads commands from file given by option -f
76 if specified; then tries to read .yazclientrc in current directory.
77 Failing that, it reads .yazclientrc from user's home directory.
79 Added support for correlationInfo Note and ID for Record Update via
82 Added yaz-client command querycharset which specifies character set for
83 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
84 (termListAndStartPoint).
86 Charset ISO5428:1984 is an alias for ISO5428-1984.
88 Implemented a way to perform scan in a result set using Z39.50. This
89 is achieved by attaching the result set name in the characterInfo
90 (type InternationalString) of OtherInformation in the Scan Request PDU.
91 The result set is identified in the otherinformation by the new OID:
92 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
93 This allows for scan in result set and faceted search . Zebra did some
94 of this in the APT term using attribute type 8 and value being result
95 set. Using the OtherInformation approach for this is cleaner and easier
96 to work with in proxies and the like. This facility can be used in
97 yaz-client using new command setscan which takes a result set as first
98 argument, start position (APT) as second.
100 Changed decoding of SRU XML packed records to deal with servers that
101 have recordData with XML data with multiple root nodes. Also make
102 comparison for recordPacking case insensitive. Again, one server
103 returns "XML" where others return "xml".
105 For SRU responses allow Content-Type application/xml as well as text/xml.
109 Fixed bug in character set conversion of BER strings. Bug introduced
114 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
116 For OID class, use oid_class consistently.
118 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
121 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
122 character set for bibliographic information interchange". By Giannis Kosmas.
124 Added documentation on new OID API.
128 Changes to generic frontend server interface: added new member
129 'query_charset' for bend_initrequest structure. A backend init handler
130 should set this member to its native character set for query terms.
131 When defined, the frontend server logic will announce this character set
132 to a client if the negotiationModel bit is set by the client. All server
133 implementors are encouraged to specify this. If a backend server does not
134 specify this a warning is issued using yaz_log(YLOG_WARN,..).
136 Added CCL utility to remove terms (stop words) from resulting RPN
137 tree. This is handled by functions with prefix ccl_stop_words_ .
139 New ZOOM C option, "rpnCharset", which allows client-side conversion of
140 terms in RPN queries.
142 Clean-up the CCL API. Moved some internal structures from ccl.h to
143 private header cclp.h. Changed ccl_parser_create so that a Bibset must
144 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
145 This is replaced by ccl_parser_find_str which takes a string instead.
147 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
148 libyaz.la is the core of YAZ except the generic frontend server and
149 does not depend on POSIX threads anymore. libyaz_server.la is the
150 generic frontend server facilities and uses POSIX thread functionality
151 if available. The libyaz.la no longer depends on POSIX threads because
152 the number of global structures is limited. NMEM no longer re-uses blocks
153 between threads ; it simply free's memory immediately but allocates in
154 "large" chunks as usual. We don't expect any performance penalties
155 because of this. The yaz_log system is still using a global log_level so
156 caution must be taken when modifying it with yaz_log_init_.. +
157 yaz_log_mask_str. This, however, should not cause any trouble because
158 these functions are called during initialization of application code
159 anyway. `yaz-config --libs server` returns libs for server applications;
160 `yaz-config --libs` returns libs for non-server applications.
162 New OID database - with public definitions in oid_db.h. Removed old OID
163 database including the head oid.h and definitions such as enum oid_value
164 and struct oident. The new OID database uses the same string names as
165 before but the 'protocol' is gone. There are now only two representations
166 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
167 converts from string to OID; functions with prefix yaz_oid_to_string
168 converts the other way.
170 Change to emit_term() in CQL-to-PQF query translation: when a term has
171 the /regexp relation modifier, do not process it for leading and
172 trailing "^" and "*", which have quite different meanings in regular
175 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
176 write handlers no longer carries a 'last' parameter. This will make
177 yaz_iconv flush "less" characters. A flush is performed by call to
178 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
180 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
181 removed, because function yaz_query_to_wrbuf does the same.
183 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
184 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
186 Deprecated MARC utility functions removed.
188 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
191 Branch split: YAZ_2_1_55_branch
193 --- 2.1.54 2007/03/16
195 Fix to ZOOM-C so that transparent reconnection is properly handled on
196 connections that are in asynchronous mode.
198 Fixed compilation on OpenBSD 4.0.
200 Large strings in GRS-1 records are now properly displayed in yaz-client.
202 Added character conversion support for "advancegreek"; based on patch from
205 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
206 sequence is met. Before the error was not set so it would be unknown.
208 Adjust yaz-marcdump MARC reader so that it skips until record separator
211 --- 2.1.52 2007/03/07
213 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
214 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
215 fd_set structure used as a bitmask for the FDs to be selected on.
217 Using ACX_PTHREAD macro to check for POSIX threads.
219 Fixed have-vsnprintf check.
221 --- 2.1.50 2007/02/23
223 Fixes for configure on BSD. Bug #900.
225 Added snprintf/vsnprintf wrappers for systems that don't have
226 limits (heavens forbid).
228 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
229 created before all previous tasks were completed and removed from the
230 task queue, the new task could be removed by a mistake.
232 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
234 Implemented pass-through CQL-to-PQF conversions. Bug #861.
236 Fixed bug #832: Problem with MARC/charset in yaz-client.
238 Fixed bug #668: save command line history for yaz-client.
240 Fixed bug #830: pkg-config support.
242 --- 2.1.48 2007/01/23
244 Extended ZOOM result set options with two options that may be read by
245 a client: resultSetStatus and presentStatus with values as specified for
247 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
249 Fixed bug #827: Using SSL fails on Debian etch.
251 Fixed bug #826: Weird looking chars for set of MARC records.
253 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
254 that is treated as an ItemOrder with itemRequest being an XML document
255 external. The value of "doc" is the content.
257 Extended the GFS search facility. New member of bend_search_rr
258 'estimated_hit_count' signals that hits is known to be an estmate
259 (higher or lower than real hit count). New member 'partial_resultset'
260 signals that the search was partial (hit count is lower or equal than
261 real hit count). For Z39.50, the information is stored in resultSetStatus
262 member of SearchResponse APDU. For SRU, the information is signalled
263 via SRU diagnostic 59: "Result set created with valid partial results
266 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
268 --- 2.1.46 2007/01/13
270 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
272 Added ZOOM_connection_peek_event.
274 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
275 the following new functions:
276 ZOOM_event_nonblock, ZOOM_connection_process,
277 ZOOM_connection_get_{socket,mask,timeout},
278 ZOOM_connection_fire_event_{timeout,socket}.
279 The existing blocking event handler, ZOOM_event, is a wrapper for the
280 + blocking ZOOM_event_sys_{poll,select}.
282 Implemented function ccl_xml_config which parses XML version of CCL
283 configuration (bug #798).
285 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
287 Added timings utility (yaz/timing.h)
289 --- 2.1.44 2007/01/03
291 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
294 Fixed bug #779: Rotation of apdu.log fails.
296 Fixed for character set conversions:
297 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
298 Honor G1 set in MARC-8 decoding.
300 --- 2.1.42 2006/12/17
302 Fixed bug #775: char conversion does not handle Alternative UTF-8
305 Implemented function yaz_marc_read_line which parses MARC line format
306 records. There is a wealth of formats out there. So far, this function
307 reads line records produced by yaz_marc_write_line.
309 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
310 more generic and easier to remember(!) options: -i format and -o format
311 which specifies input format and output format respectively - where
312 format is one of "marc", "marcxml", "line", "marcxchange".
314 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
315 does not print anything except warnings for records.
317 For yaz-marcdump, added support for MARC split into files (-s) with a given
320 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
321 spec, at http://www.loc.gov/standards/sru/record-update/
322 This has changed the binary layout of the following structs:
323 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
324 bend_update_rr . Patch by Ko van der Sloot.
326 Added GFS utility function bend_assoc_is_alive which returns 1 if
327 association is still alive (client is connected); 0 otherwise (client
328 closed connection). This allows busy servers to stop working for
331 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
332 been a separate piece of software. This version of ziffy has been modified
333 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
335 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
337 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
338 Client code may now interrogate options such as "init_opt_sort" to
339 find out whether the server claims to support various options.
341 --- 2.1.40 2006/11/27
343 Added utilities yaz_{set,get}_esn to set/get element set name from
346 Removed the build of libyazthread.la. The libyaz.so is the threaded version
347 of YAZ and has been so since YAZ 2.1.10.
349 Implemented ZOOM_record_error which returns error information for
350 record (surrogate diagnostic).
352 --- 2.1.38 2006/10/31
354 Updates for SRU Update by Ko van der Sloot:
355 1. Changed name from "operation" to "action"
356 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
357 versions in the code, marked as 'backward compatible'.
358 3. Added diagnostics for SRU Update.
360 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
362 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
364 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
366 For GFS, fixed problem with SRU diagnostic 'First record position out of
367 range' being issued for 0 hits.
369 zoomtst10 part of Windows Build.
371 --- 2.1.36 2006/10/13
373 Implemented yaz_filepath_comp which splits a path into file path
374 components (required by Zebra 2.0.3+).
376 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
377 BSD inspired license until now so this should not have any real impact on
378 anybody. See http://www.opensource.org/licenses/bsd-license.php
380 Fixed bug #687: Missing log lines.
382 Fixed bug #678: CQL to PQF translation does not preserve double-quote
385 Fixed bug #689: SRU diagnostics to be added.
387 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
388 whether a connection is idle (no more work do do).
390 --- 2.1.34 2006/10/04
392 Change type of optval from long to int for invocation of setsockopt with
393 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
395 Added support for specifying the max log file size for the Generic
396 Frontend Server. The size is given with option -r.
398 --- 2.1.32 2006/09/21
400 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
402 --- 2.1.30 2006/09/17
404 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
407 Fixed bug in Generic Frontend Server that could cause a server to stop
408 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
410 For the generic frontend server, the maximum record size is used as maximum
411 size of incoming packages (SRU + Z39.50). The value until was previously
412 only used in Z39.50 Init negotiation and, later, in a session controlled
413 sizes of records returned. This is controlled using -k option. It can be
414 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
416 --- 2.1.28 2006/09/04
418 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
421 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
423 New option for yaz-marcdump -lpos=value which allows setting a portion
424 of MARC header to a certain value.
426 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
428 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
429 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
431 --- 2.1.26 2006/08/15
433 Fixed problem with SRU mode type (soap, get, post) for yaz-client
436 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
438 --- 2.1.24 2006/08/08
440 Fixed MARC ISO2709 encoding routines to deal with character set
443 Minor changes to GFS logging. Database included in search request log
446 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
447 cached/multiple records.
449 Shared libraries are built by default on Unix+configure.
451 Changed cql2pqf transformation to use a different evaluation order. The
452 new order is: always, relation, structure, position, truncation, index
453 and relationModifier. Old order was: always, relation, relationModifier,
454 structure, index, position, truncation. Note that the the latter ones
455 override former ones for identical attributes.. The new scheme means that
456 it is possible to override any existing attribute with a relationModifier.
457 And also that it is possible to override everything for the index rule
458 (except the ones listed in relationModifier). No order is perfect but this
459 one, we believe, covers more real cases.. The "always" should have been
460 called "default", since the attributes there can be overridden with all
463 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
464 compilation phase, but also for yaz-config --cflags output. This allows
465 us to have public headers with Libxml2 stuff in them . It should also,
466 eventually, make Libxml2 checks redundant in packages using YAZ, such
469 --- 2.1.22 2006/06/15
471 Changed SRU update structure bend_update_rr so that SRU diagnostics are
472 stored in uri, message and details.. Previously diagnostics were stored
473 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
474 compatibility.. but he's probably the only one affected, so.
476 Added support for CCL, compiled on the client side, in ZOOM-C. This
477 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
478 input; the resulting query objects can be used for for searching with
479 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
481 YAZ' configure searches for OpenSSL by default.
483 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
484 SL_CTX_use_certificate_file. See
485 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
486 for more info. Thanks to Ko van der Sloot.
488 --- 2.1.20 2006/06/02
490 Bug #600: SRU GET, POST support for yaz-client. Introduced
491 command 'sru' which selects method SOAP/GET/POST.
493 Allow missingValueAction to be specified for the sortspec string -
494 function yaz_sort_spec. By default, the missing value action is null.
495 Use ! to specify "abort". Use = followed by stringvalue to specify default
498 Ensured that Present-handler (if defined) is called in GFS before any call to
499 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
500 searchRetrieve requests.
502 Documentation for YAZ is now based on the Docbook XML/XSLT using
503 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
504 is no longer depending on jade/openjade or docbook-to-man scripts.
505 PDF is no longer part of the distribution - but can optionally be
506 made using DSSSL/jadetex or FOP.
508 Added retrieval handling support in Generic Frontend Server to support
509 conversion between MARC/XML as well as XSLTtransforms. See
510 etc/yazgfs.xml for an example.
512 Added Authentication support to Generic Frontend Server in SRU
513 mode. Authentication using HTTP Basic is supported, as is the use
514 of 'x-username' and 'x-password' parameters in the request itself.
516 Added support for a new character set MARC8s identical to MARC8 except
517 that it converts combined characters to single Unicode characters in the
518 Latin-1 range (when possible).
520 --- 2.1.18 2006/04/24
522 ASN.1 compiler 0.4: generates brief Doxygen file header for
523 generated .h/.c files.
525 Utility yaz_iconv now supports conversion to MARC-8.
527 New facilities for the MARC module. The reading - and writing of
528 content are separate methods for the yaz_marc_t handle. The following
529 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
530 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
531 format). Write functions have prefix yaz_marc_write_.. The existing
532 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
533 available. Removed support for OAI-MARC and simplexml (not the
534 simplexml from PHP5).
536 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
537 to be returned for this connection.
539 --- 2.1.16 2006/03/31
541 Allow multiple languages and charsets to be specified with
542 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
543 negcharset iso-8859-1,utf-8
545 Translation of proximity nodes from CQL into PQF now works.
547 Moved to automake 1.8, 1.9.
549 Added function yaz_log_set_handler which allows a log handler to be
550 installed. This handler will be called for all log messages. Output
551 to file is also produced; but that can be disabled by passing NULL
552 fname to yaz_log_init_file.
554 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
556 For SRW (including GFS), accept application/soap+xml as content-type
559 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
560 produces NO stylesheet reference even if a default stylesheet is specified
563 --- 2.1.14 2006/03/14
565 Updated Windows package to include yazd.dll + yazd.lib for the
566 Development component.
568 If the environment variable YAZ_LOG is set, then it is used as a
569 string indicating the default level of logging to use if not
570 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
571 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
572 used as before. So, for example, to omit warnings from YAZ logging,
575 cql_transform() now map structure and other attributes before indexes,
576 so that index-specific structures and other attributes can override
577 defaults. So now a combination of mapping specifications such as:
579 index.dc.date = 1=date-modified 4=5
580 does the right thing.
582 cql_transform() now also respects the "always" mapping specification,
583 which establishes an initial set of attributes to be used for all
584 terms except where overridden by more specific attributes associated
585 with the index, relation or modifier.
587 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
588 which mode to use; one of "post", "get" or "soap" (SRW, default).
590 Fixes for yaz_iconv routines: changed trie-based character set conversions
591 to use only non-negative values for bit fields due to Sun's C compiler not
592 supporting negative values.
594 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
595 sequences where not read correctly. Fix by Rustam Usmanov.
597 Updated win/makefile to use options, settings which makes things
598 compile with VS C 2005.
600 --- 2.1.12 2006/02/01
602 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
604 In ZOOM socket code, use select instead of poll on MacOSX.
606 ZOOM-C now support client-side compilation of CQL into RPN that is
607 sent to the server, enabling CQL to be used against all Z39.50
608 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
609 ZOOM_query object, and submit it using ZOOM_connection_search().
610 The CQL-to-RPN translation uses a configuration file, the name of
611 which must be specified in the Connection's "cqlfile" option.
613 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
614 function, which takes as its start-term parameter a ZOOM_query object
615 (which may have had either CQL or RPN set into it).
618 --- 2.1.10 2005/11/29
620 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
621 GFS to support this as well. Backend handler, bend_srw_update, does the
622 update work. Code contributed by Ko van der Sloot.
624 Allow retrieval of Search Result-1 information in ZOOM by the use of
625 options that are attached to a result set. ZOOM documentation updated
628 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
629 UTF-8 conversion. Patch by Raj Patel.
631 Added option -m to GFS to control formatting of timestamps in log file.
633 Added 'exit' as synonym for 'quit' in yaz-client
635 Added support for specifying SRW resultSetId + resultSetIdleTime in a
636 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
637 for the new members. Patch by Ko van der Sloot.
639 Added support for SRU POST. It is supported for content-type
640 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
642 Do not build the separate Multi-threaded (MT) library libyazthread.la.
643 Instead make the library libyaz.la multi-threaded. Threading as a whole
644 can still be disabled by configure option --disable-threads. Previosly,
645 with older GLIBCs there were problems with MT libs under Apache. This
646 has now been fixed a long time ago.
648 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
651 CQL module modified to be case insensitive for relations/indexes/operations.
653 Fixed bug in CQL transform code: incorrect value relationModifieder
656 Added 'show all' command for yaz-client which retrieves all results
659 Added new yaz-client, xmles, which takes a (private) OID and
660 a document to be sent as an extended service request.
662 Describe new yaz-client commands wait_response and set_auto_wait.
664 Increase TCP/IP listener backlog from 3 (which I am guessing was
665 copied from the SunOS manual entry way back when) so SOMAXCONN, so
666 that the socket will queue as many incoming connections as it's able
667 to handle ongoing connections. In other words, it will never now
668 refuse a connection that it would be able to handle merely because
669 it's not got around to accepting() enough of the pending connections
670 yet. This is the behaviour anyway under Linux, where the listen()
671 argument is ignored; but not under BSD and on systems such as
672 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
673 YAZ-based servers should now be uniform across operating systems in
676 yaz-marcdump uses 64-bit file access on some systems. This is enabled
677 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
678 This allows yaz-marcdump to read large MARC batches (>2 GB).
680 Modified all YAZ source files - except the source which is auto-generated
681 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
684 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
685 corresponding to the existing *_setl() function. These allow option
686 values containing arbitrary valuues.
688 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
689 ZOOM_resultset_sort() in new applications. Its behaviour is identical
690 except that it returns an indicator of whether or not the sort
691 criterion was accepted (0 for OK, -1 for invalid).
695 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
696 MARC output rather than returning "new" buffer.
698 yaz-client warns about unknown init options.
700 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
704 Added support for SRW sort in Generic Frontend Server. Patch
705 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
706 sortKeys - or NULL if none is provided.
708 Fixed bug #307: It was impossible to specify indefinite/no timeout
709 for ZOOM_event. Special timeout value -1 now means indefinite timeout
712 Added support for multiple languages and charsets to be specified in
713 ZOOM. Each charset/language is separated by a blank. If negotiation is
714 in effect in init-response, Option
715 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
716 Code based on patch by Vasiliy Osadchuk.
718 Fixed bug #306: infinite recursion that occurred when calling
719 yaz_log_level_init as the first call (before other log level or
722 Fixed bug in scan handling in front end server: if preferred-Position-In-
723 Response was non-present, a NULL pointer referece was performed.
727 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
728 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
729 now defined for all those error codes. So instead of putting 109 in
730 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
731 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
733 Modified the yaz-marcdump utility to skip garbage bytes between MARC
736 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
738 Program yaz-client now exits and produces an error message if multiple
739 Z39.50 servers are specified on the command line (none or one allowed
742 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
747 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
749 Fixed bug #272: Preserve spacing for CCL terms.
753 Added support for virtual hosts and multiple backend servers for
754 the YAZ frontend server. The configution is XML based and
755 support specificition of CQL to RPN mappings and explain information.
756 See section "Virtual Hosts" in the YAZ manual.
758 Extended OPAC display utility. OPAC display utility renders
759 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
760 to supplement yaz_marc_decode_wrbuf.
762 Fixed a bug in MARC decoder that could caused it to crash for some
763 invalid MARC records. More diagnostics and warnings where added in
764 XML output (warnings, etc are stored in comments).
766 --- 2.0.34 2005/02/08
768 Fixes for UNIX domain sockets. Bug #261.
770 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
772 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
773 Added yaz_marc_subfield_str which defines subfield lead string which is
774 used in YAZ_MARC_LINE format. Default string is blank+$. Added
775 yaz_marc_endline_str which defines end of fields string used in
776 YAZ_MARC_LINE format. Default string is newline.
778 Experimental support for MarcXChange. This format can be produced
779 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
780 http://www.bs.dk/standards/MarcXchange.xsd
782 Added yaz-client commands scansize that sets maximum number of
783 entries to be returned by scan.
785 --- 2.0.32 2005/01/11
787 Added support for SRW scan in yaz-client and Generic Frontend Server.
789 * Added whereInList member to SRW Scan Term.
791 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
793 Fixed NMEM system to return aligned blocks on the smallest boundaries
794 that are suitably aligned for all possible types on the particular
795 architecture YAZ is being built for.
797 --- 2.0.30 2005/01/04
799 Fixed numerious warnings that was issued with newer versions of GCC.
801 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
802 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
805 Make YAZ Generic Frontend Server slightly faster.
807 Enhance (and reduce) logging for Generic Frontend Server.
809 Revert YAZ log system so that it flushes every write operation
810 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
812 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
813 instead of LOG_, due to name clash with syslog(3). LOG_ are still
814 present. New applications should define YAZ_USE_NEW_LOG=1 - this
815 will effectively disable old definitions.
817 --- 2.0.28 2004/11/09
819 Added yaz_log_time_format which specifies log format using
822 Added yaz_log_module_level which returns mask for a module. Value
823 is non-zero mask a if module is enabled; zero if disabled.
825 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
826 in include/yaz/cql.h.
828 Fixed bug #176: Dont throw diagnostics on empty SRU args.
830 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
832 Fixed bug #172: RPM builds does not enable SSL.
834 Doxyfile.in part of dist. Doxyfile generated by configure.
836 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
837 are given and the corresponding component does not exist.
839 Extend CCL documentation in YAZ reference. Describe r=r.
841 --- 2.0.26 2004/10/01
843 Fixed MARC->MARCXML conversion to properly deal with
844 fields, subfields, indicators having non-ASCII characters.
846 Fixed MARC->MARCXML conversion so that ASCII control characters
847 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
850 Added YAZ GFS support for conversion from Z39.50 surrogate
851 diagnostics to SRW surrogate diagnostics.
853 Bug fix: YAZ GFS did not return schema in explainResponse.
855 --- 2.0.25 2004/09/30
857 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
858 now converts recordSchema to elementSetName as well as schema URI.
860 Fixed bug in COMSTACK that prevented HTTP request packages from being
863 --- 2.0.24 2004/09/29
865 Added CCL facility r=r "range" which is similar to r=o "ordered" but
866 does not require white-space before and after the dash in a range, e.g.
867 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
870 Fixed a few AC_TRY_LINK configure tests that did not operate properly
871 due to new GCC removing "redundant" code.
873 Added yaz-client commands scanpos and scanstep that sets preferred
874 position and step-size for scan.
876 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
878 Added CCL utility ccl_qual_buf which parses one or more CCL
879 spec lines in a buffer.
881 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
882 of name and value - ignoring empty lines and comments.
884 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
886 Added odr_get_element_path which returns current element path for an
887 ODR handle. This utility is useful in error handling or user-defined
890 Added ODR_PRINT utility odr_set_stream which is is a more generic
891 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
892 to a write function and pointer to close function. The close function - if
893 non-NULL - will be called during odr_destroy.
895 Fixed bug in CCL parser where truncation char was not removed from
896 right side when truncation=both was in effect.
898 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
901 --- 2.0.23 2004/08/11
903 Fix buffer overrun in CQL parser when dealing with proximity (%).
905 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
906 to UTF-8/UCS conversion is now only based on codetables.xml.
908 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
910 --- 2.0.22 2004/08/06
912 Add support for more "commit changes" in ZOOM (uses Extended Services).
914 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
917 Yet another small fix for configure of SSL.
919 --- 2.0.21 2004/05/14
921 Fix SSL libs for configure when --with-openssl=DIR is given.
923 --- 2.0.20 2004/05/10
925 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
927 SSL comstack now uses yaz.pem certificate file on server side
928 by default. Certificate filename can be configured by calling
929 comstack function cs_set_ssl_certificate_file before cs_bind is used.
931 Fix bug regarding multiple calls to ZOOM_connection_connect.
933 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
935 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
936 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
938 ZOOM now allows inspection of X509 peer certificate for verification.
939 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
941 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
942 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
943 as "modular" but it simplifies things.
945 Added cs_get_peer_certificate to that returns peer X509 PEM.
947 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
948 NULL if SSL is unavailable.
950 Documentation about MARC decoding tools.
952 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
954 --- 2.0.19 2004/03/30
956 Rename CHANGELOG to NEWS to follow GNU style packing.
958 Fix bug with missing initialization of member in init_diagnostics.
959 This bug affects threaded version of GFS server.
961 --- 2.0.18 2004/03/20
963 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
966 Ensure zlib.dll is packed with Windows install.
968 --- 2.0.17 2004/03/17
970 Fix encoding of xsd:string to use text instead of CDATA.
972 Fix endless loop in CQL parser with unbalanced ".
974 Use a more compact way to store MARC-8 conversion tables.
976 --- 2.0.16 2004/03/16 Debian only
978 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
981 Update CQL parser to use new CQL 1.1 modifiers for booleans and
986 --- 2.0.15 2004/03/01
988 Another fix for decoding of XML packed records.
990 --- 2.0.14 2004/02/25
992 Fixes for Chunked encoding. White space not ignored after length spec.
994 Update NS and use default NS for SRW diagnostic elements.
996 --- 2.0.13 2004/02/23
998 Implement ZOOM_resultset_cache_reset which resets record cache.
1000 Implement ZOOM_resultset_sort which sorts a result set.
1002 Implement chunked HTTP transfer.
1004 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1006 --- 2.0.12 2004/02/16
1008 Added member 'schema' to bend_explain_rr structure so that backend
1009 can specify explain record identifier. Defaults to Zeerex 2.0.
1011 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1013 --- 2.0.11 2004/02/16
1015 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1018 Added init command for yaz-client which sends "extra" init request.
1020 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1021 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1023 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1025 Make ZOOM error code for "invalid query".
1027 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1029 --- 2.0.10 2004/02/05
1031 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1034 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1036 Added option -p <file> to make Generic Frontend Server to write PID file.
1038 Added option -D to put Generic Frontend Server in background on its own.
1040 Make ZOOM C recognize option "password". If unset, "pass" is used
1041 (for backwards compatibility).
1043 Fixed a bug in Generic Frontend Server that could make it crash if a
1044 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1047 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1048 Must be issued before open, in order to be in effect.
1050 --- 2.0.9-6 2004/01/12 Debian/Windows
1052 Make the SRU server more picky WRT unknown params, etc.
1054 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1056 New YAZ client command, options, that sets Z39.50 options.
1058 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1059 options from a string of tokens (one token for each option bit).
1061 Update SRW diagnostic code messages.
1063 --- 2.0.9-5 2004/01/07 Debian/Windows
1065 Handle user defined stylesheet for SRW/SRU.
1067 --- 2.0.9-4 2004/01/06 Debian/Windows
1069 Fix bug in decoding of Content-Length.
1071 --- 2.0.9-3 2004/01/06 Debian/Windows
1073 Fix a bug with decoding of XML packed records.
1075 --- 2.0.9-2 2004/01/05 Debian only
1077 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1079 Fix bug in SRW/SRU diagnostics decoding.
1081 --- 2.0.9 2004/01/05
1083 Fixed bug in Generic Frontend Server which could drop records exceeding
1084 preferred message size. Reported and fixed by Irina Dijour.
1086 Fixed calculation of package size for structured records in Generic
1087 Frontend Server. Reported and fixed by Irina Dijour.
1089 Fixed namespace for SRW/SRU diagnostics.
1091 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1093 --- 2.0.8 2003/12/22
1095 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1096 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1099 CQL changes to reflect recent changes to the specification:
1100 * Documentation talks about context sets instead of index sets.
1101 * Documentation talks about indexes instead of qualifiers.
1102 * The CQL-to-PQF transformer's configuration file now uses
1103 "index.set.name = <attributes>" instead of the old form
1104 "qualifier.set.name = <attributes>". (Both forms are still
1105 understood but the latter is deprecated.)
1106 * CQL terms with no explicit index specified are now interpreted as
1107 cql.serverChoice instead of srw.serverChoice (which of course
1108 behaves exactly the same.)
1110 --- 2.0.7 2003/12/16
1112 MARC conversion can now generate ISO2709 output in another
1113 character set. yaz-marcdump uses this facility if you invoke it
1116 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1117 functions from there can be used from C++.
1119 --- 2.0.6 2003/12/04
1121 Frontend server now transfers memory from decoded packages to stream
1124 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1125 references to show up.
1127 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1128 the ZOOM Abstract API. The older names for the same options are still
1129 also supported for the benefit of old applications.
1131 ZOOM-C supports "implementationId" and "implementationVersion" options
1132 to go along with "implementationName". These allow the user code to
1133 specify identification strings to be sent to servers.
1134 Add OID for the new ExtLite attribute set.
1136 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1137 as requested/supplid by Ere Maijala <ere@atp.fi>
1139 For generic frontend server, reverse the order of
1140 "toolkit-supplied / application-supplied" strings sent as implementationId,
1141 Name and Version. Also, remove the spaces around the slash. This brings
1142 the GFS in line with the behaviour of ZOOM-C on the client side.
1144 Add function ZOOM_scanset_display_term.
1146 yaz-client shows scan displayTerm if present.
1148 Utility yaz-iconv is now installed by default along with the man page
1151 Extend configure check for OpenSSL to use pkg-config where available (such
1154 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1155 server to specify uid/gid/mask for socket using the format
1156 unix:[user=uid,][group=gid,][umask=mask,]file=path
1157 If file= is omitted the existing format is assumed, e.g.
1159 in which case the mask is 0666 (rw for everybody).
1161 Major restructure of YAZ source. All source in libyaz is in src directory.
1162 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1163 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1165 Added man page for utility yaz-marcdump (used to be called marcdump).
1166 yaz-marcdump is installed by 'make install'.
1168 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1169 of incoming package failed.
1171 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1173 Change prototype of odr_perror: add const to message string.
1175 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1177 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1178 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1179 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1180 DNS lookup. There should not be any compatibility problems with this
1181 assuming that blocking=1 or 0 is used.
1183 Fix bad reference in UNIX comstack in function cs_addrstr.
1185 Fix for compilation on AIX.
1187 The generic front-end server (server/seshigh.c) now supports returning
1188 Init diagnostics to the client in User-information-field, in
1189 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1192 --- 2.0.4 2003/09/04
1194 Allow any CQL relation (not just all,any,exact,scr).
1196 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1197 that features the same UI.
1199 Implemented command update0 in YAZ client which is equivalent to
1200 update but uses old of Ext Update ASN.1.
1202 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1203 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1204 Previously no OID was used for this info.
1206 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1207 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1208 returns 'malformed search term' otherwise.
1210 SortResponse member resultCount now set to NULL in sort handler of
1213 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1216 Add three new utility functions for translating OIDs between various
1217 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1218 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1219 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1220 char *oid_to_dotstring(const int *oid, char *oidbuf);
1221 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1223 Reverted modifications for ES Update definition for z_IU0Update
1224 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1225 is back to YAZ 2.0.2.
1227 String value attributes for CCL parser.
1229 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1230 which their FirstSearch server returns in Init responses, sometimes
1231 carrying useful diagnostic information when Init fails. This has the
1232 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1233 "z39.50/oclcui.asn", where its definition is somewhat different from
1234 what OCLC document on their web-site, as required to interoperate with
1237 Support for anonymous authentication in yaz-client. Use the command
1240 * Fix the OID of the Index Data-local "admin" Extended Service from
1241 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1242 the 1000, which indicates a locally-defined OID, was a mistake.
1244 --- 2.0.3 2003/06/20
1246 Fix CCL directive @case handling so that it affects string match for
1247 both CCL keywords and qualifiers.
1249 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1250 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1251 Decoder has been updated with ASN.1 changes as listed in
1252 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1253 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1254 z_IUUpdate, remains unchanged.
1256 ZOOM_record_get may now return a record in a specific character set.
1257 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1258 "from" is the character set of record as returned by target. "to" is
1259 the character set to be returned. If omitted, "to" is UTF-8.
1261 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1263 New ODR utility, odr_getelement, which returns name of element for
1264 which encoding/decoding failed.
1266 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1267 in cases where a required element was omitted.
1269 Bug fix: some MARC8 sequences were not converted.
1271 New ZOOM option "step" which specifies number of records to be
1272 retrieved in one chunk. Used in conjunction with "start" and "count".
1274 SRW support for yaz-client. Use scheme http: to use it, e.g.
1277 yaz-client no longer does (un)intelligent character set conversions
1278 by default. Can be enabled with charset and marc_charset commands.
1280 xmalloc trace fix for 64-bit systems such as DEC alpha.
1282 Solaris 2.6 compile fix.
1284 New function, cql_strerror() translates SRW error codes, as returned
1285 by cql_transform_error(), into human-readable English strings. Used
1286 in yaz-client diagnostics when appropriate.
1288 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1289 converts it into a type-1 query which is sent to the server. This
1290 makes CQL available for use with all Z-servers, as opposed to the tiny
1291 minority that can handle CQL queries themselves.
1293 --- 2.0.2 2003/04/28
1295 New Debian package layout similar to the Redhat Package layout.
1297 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1298 and search result respectively.
1300 --- 2.0.1 2003/04/25
1302 Redhat package is now several packages: libyaz (runtime libraries),
1303 libyaz-devel (development and documentation, and yaz (utility programs).
1304 Package spec file by Morten Bøgeskov.
1306 New member 'schema' in struct bend_fetch_rr which the name of requested
1307 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1308 handler MAY set this to reflect the schema of the returned record.
1310 New member 'display_term' in struct scan_entry. GFS now sets member entries
1311 and allocates scan entries to be filled by user scan handler. In previous
1312 version, entries member was allocated by the scan handler. That still works,
1313 but the GFS will ignore member display_term - assuming it was NOT set by
1314 the handler. The fact that the GFS now allocates the entries both allows
1315 for new members and makes a scan handler easier to write.
1317 Fix CQL lex buffer overflow.
1319 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1320 SRU default recordPacking is string.
1322 SRU protocol support for frontend server.
1324 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1326 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1328 Added scan for the ZOOM shell (zoomsh).
1332 * String Identifers for Schemas (Amendment 5).
1333 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1334 Old definition for schema
1335 Odr_oid *schema; /* OPT */
1340 Z_InternationalString *uri;
1341 #define Z_Schema_oid 1
1342 #define Z_Schema_uri 2
1345 * resultCount parameter to Sort Response (Amendment 1).
1346 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1348 Support for SRW 1.0 over HTTP. This is an optional feature and
1349 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1352 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1353 on the same port. SRW SearchRetrieveRequests are mapped
1354 to bend_init,bend_search,bend_fetch,bend_close.
1356 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1358 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1359 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1361 ZOOM connections are SRW based if schem http is used for hostname
1362 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1363 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1365 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1366 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1367 distance=n, order=true/false, relation=le, prox unit=word. If
1368 n is omitted, distance 1 is used.
1370 Fixed problem with C compiler include path in wrong order.
1372 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1373 on Solaris. Patch from Ko van der Sloot.
1375 New MARC decode API. All new functions operate on a yaz_marc_t
1376 handle. The most important new functions are: yaz_marc_create,
1377 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1378 decode and destroy respectively. Decoder can produce formats
1379 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1380 include/yaz/marcdisp.h.
1382 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1383 to UTF-8, UCS-32, wchar_t or Latin-1.
1385 * Prototypes for yaz_iconv_-functions moved to separate header
1386 include/yaz/yaz-iconv.h.
1388 Make a few private functions 'static' in unix.c. This prevents
1389 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1391 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1392 are set when Init Response is received.
1394 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1395 but returns diagnostic set as well.
1397 New function yaz_strerror which is a portable wrapper for
1398 strerror/strerror_r/GetLastMessage.
1400 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1401 is returned for MARC. If type is "oai", then OAI MARC is returned.
1403 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1406 --- 1.9.2 2002/11/26
1408 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1410 Fix bad race conditions on SIGTERM and terminate gracefully in
1413 Move retrieval (data1) module to Zebra since nobody seems to be
1416 Add GRS-1 render for ZOOM using same format as yaz-client.
1418 --- 1.9.1 2002/10/05
1420 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1422 Fix broken ESpec handling in data1 module.
1424 SGML reader parses comments and makes them part of the data1 tree.
1426 Added several type casts so that YAZ compiles as C++ code.
1428 ZOOM didn't handle PDU encoding failures properly.
1430 Added more Bib-1 diagnostics (approved extensions).
1432 GNU configure: better check for iconv.
1434 More portable use of accept, getpeername. Check for socklen_t. Use
1435 int/size_t if socklen_t is not defined.
1439 PQF parser rejects bad queries - including those with extra
1440 characters in them. PQF parser used to silently ignore that.
1441 Cleaner API for PQF added, which allows you to get detailed
1442 error information for bad queries (see yaz/pquery.h).
1444 Fixed bug in ZOOM_record_get for type "database".
1446 Implemented mini iconv library supporting conversions between
1447 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1449 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1451 --- 1.8.9 2002/08/20
1453 Fixed ZOOM C record cache so that preferredRecordSyntax and
1454 elementSetName is used to check for already fetched records.
1456 --- 1.8.8 2002/08/02
1458 Added three members in bend_initrequest structure to facilitate
1459 character set negotiation.
1461 Fixed a bug in frontend server that could cause indefinite
1462 loops under rare conditions.
1464 Revised character set utilities (charneg.h) so that encoding
1465 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1467 For PQF, directive @term <type> sets term type for Scan/Search.
1468 Here <type> is general, string, numeric, null. The term type
1469 is inherited - just like @attr.
1471 New call odr_set_charset that sets character set conversion for
1472 international-strings on a ODR stream. Prototype is:
1473 int odr_set_charset(ODR o, const char *to, const char *from);
1474 The InternationalString is still represented as C string in YAZ
1475 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1476 won't). On the protocol level, you can use any encoding.
1478 Support for UNIX sockets in ZOOM.
1480 Solaris recv sometimes returns errno == ENOENT. It is treated as
1481 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1483 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1484 both client and server. Code by Morten Bøgeskov.
1486 --- 1.8.7 2002/05/22
1488 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1489 that they can be used directly from Visual Basic. You must recompile
1490 your windows APP if you're using ZOOM.
1492 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1493 Commands "lang" and "charset" sets language and character set respectively.
1494 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1495 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1497 Attributes from multiple CCL fields may be OR'ed rather than merged
1498 using directive "@field or". Fields are still merged by default -
1499 equivalent to "@field merge".
1501 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1504 Fixed bug in zget for parameter ExtendedServicesResponse.
1508 --- 1.8.6 2002/03/25
1510 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1512 Client displays USR.1:SearchResult-1 (hits per term).
1514 Additional Search Info for search in Generic Frontend Server.
1516 Fixed CCL parsing of "field=s".
1518 WIN32 installer - using the excellent NSIS software from nullsoft.
1520 Fixed CCL parsing of "field = - <number>".
1522 Added function yaz_marc_decode that decodes MARC for line mode
1523 display or XML (similar to that used by JZKit).
1525 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1526 Z39.50. But ISO/ILL was, however.
1528 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1529 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1531 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1532 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1534 --- 1.8.5 2002/02/03
1536 New YAZ client features: Command completion and new commands:
1537 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1538 Code provided by Jacob Poulsen.
1540 New call oid_trav, that visits all registered OIDs via callback.
1542 Function ZOOM_record_get now returns const char pointer rather than
1543 void pointer. It saves a lot of type casts.
1545 For YAZ client, command "auth" now allows you to set authentication
1546 in IdPass style. It is enabled when three tokens are given - order
1547 is user, group and password.
1549 Fix memory leaks in MARC record handling for ZOOM.
1551 New option for YAZ client, -k <kilobytes> that sets
1552 maximum record size. Similar to -k option for generic frontend
1553 server and yaz-ztest.
1555 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1557 Prefix query parser reports "fail" when bad attribute set is given.
1559 Fix in MARC decoder. Proximity logging. Fix for attribute set
1560 in scan handler for server. Patches by Shigeru Ishida.
1562 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1565 Configure option --with-openssl=<dir> now works when a directory is
1566 specified. Patch provided by Morten Bøgeskov.
1568 New option for YAZ client, -u <auth>, that sets authentication.
1570 ZOOM fix: error information was sometimes "missing", since error
1571 was cleared/reset too when it shouldn't.
1573 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1575 --- 1.8.4 2002/01/04
1577 Scan for ZOOM API. New object ZOOM_scanset. New functions
1578 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1579 ZOOM_scanset_destroy.
1581 New ZOOM function, ZOOM_connection_last_event, that returns type
1582 of last event (such as "receive data", "send data", "apdu received",
1585 New ZOOM option, schema, that specifies schema for retrieval.
1587 New CCL feature. Qualifiers can be aliases for one or more
1588 other qualifiers (if more than one is given, OR is used).
1590 ZOOM uses named result sets if target supports it.
1592 Two new YAZ client commands: . (dot, which sources a script of YAZ
1593 client commands), and ! (to execute shell command.). Implemented
1596 Working on Debian packages.
1598 --- 1.8.3 2001/11/19
1600 YAZ client enables named result sets only if target supports it.
1602 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1604 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1605 with key="host" to get same result.
1607 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1608 Function Z3950_resultset_record(s) returns references to records
1609 "owned" by resultset. To become owner use Z3950_record_clone.
1611 Function z_ext_record handles Extended Services. Thanks to
1614 --- 1.8.2 2001/11/12
1616 CCL Parser fix: ignore token comma when dealing with and-lists.
1618 Documentation updates for COMSTACK.
1620 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1621 Changed prototype Z3950_records. For some functions, int parameters
1622 were changed to size_t.
1624 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1627 New MARC decode/display function, marc_display_exl, which properly rejects
1628 non-ISO2709 records. YAZ client uses it.
1630 --- 1.8.1 2001/10/29
1632 Fix bug: local attribute set wasn't set correctly in PQF strings.
1636 * Old Z39.50 codecs no longer supported.
1638 Added ZOOM C binding. See http://zoom.z3950.org/
1640 Renamed states for COMSTACKs to avoid confusion with events.
1642 Implemented cs_look and proper cs_rcvconnect.
1644 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1646 Configure detects POSIX threads on OpenBSD.
1648 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1649 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1651 When error is returned from present handler, non-surrogate diagnostic
1652 is returned in present response (and fetch handler is no longer called).
1654 * Minor adjustments to pquery parser (PQF). Token characters may be
1655 escaped by using backslash (C-style).
1657 PQF parser allows string attribute values to be specified. For @attr,
1658 non-numeric characters after the equal-sign are treated as strings
1659 (e.g. @attr 9=title).
1661 CCL trunction character may be defined (@truncation in file)
1663 * function zget_ExtendedServicesRequest sets waitAction to
1664 waitIfPossible (was wait).
1666 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1669 CCL operator names may be set in field definition files (CCL_bibset).
1670 See ccl/bib1 for an example.
1672 Fixes in ASN.1 compiler for C++ compatibility.
1674 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1675 and "op_or" to avoid conflict with C++.
1677 Fixed problem with GNU readline detection on Redhat 7.0.
1679 Added step-size for Scan backend handler.
1681 Fixed bug that made the frontend server crash when no attribute
1682 set was specified for scan.
1684 Front-end server automatically switches to original working directory
1685 when installed as an NT service. Previously -w had to be specified to
1688 Added extended attributes for retrieval module (data1), so that data1
1689 records carry d1_readXML/SGML attributes. d1_read also supports
1690 null-data rules ( <tag/>)
1692 On UNIX when POSIX threads are available, a separate library libyazthread
1693 is created. Programmers should link with that library and the yaz library
1694 when using threads. The reason for the split was that some applications
1695 on Linux, such as Apache, doesn't work well when using shared objects that
1698 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1699 (or any frontend server) in SSL mode by specifying ssl: followed by
1700 address. Only tested on UNIX.
1702 Added feature for CCL module. Virtual structure s=al or s=ol generates
1703 and-list and or-list respectively instead of phrase search.
1707 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1708 log_mask_str. This was done to avoid name conflicts with other libraries
1709 (such as other PHP extensions).
1711 Added raw OID member for preferred record syntax (request_format_raw)
1712 and returned record syntax (output_format_raw) for backend fetch method.
1714 Config file yaz-config now accepts options so that it returns specific
1715 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1717 Shared library support for UNIX using GNU libtool.
1719 * Modified backend interface. Request/Response struct's replaced by
1720 one read/write C struct. For example bend_fetchrequest and
1721 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1722 Every handler - even search has to be registered in bend_init
1723 handler. This means that the YAZ library no longer refers to
1724 external functions and it makes it possible to make the whole
1725 thing a single DLL/SO.
1727 Added Segment handler for backend server.
1729 Added Zmbol/Zebra administrative functions to YAZ client.
1731 Threaded frontend server on UNIX (when POSIX Threads are available).
1732 Starting the server with option -T enables multi-threading.
1736 Added configure option --enable-comp/disable-comp to control use
1737 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1738 located in sub directory asn.
1740 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1741 in ${exec_prefix}/bin along with the other programs yaz-client and
1744 GNU automake used to maintain makefiles.
1746 Added several OID's.
1748 Changed retrieval module so that we can load records with no abstract
1749 syntax defined. Tagpaths in these records are fully composed of string
1752 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1756 On UNIX, the generated makefile now supports a proper 'make install'.
1757 The prefix can be set via GNU configure to set the install location
1758 (default is /usr/local).
1760 * YAZ programs client and ztest were renamed to yaz-client and
1761 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1762 locations, such as /usr/bin,/usr/local/bin,etc.
1764 * YAZ Header files were moved from include to include/yaz. YAZ Header
1765 files are referred to as include <yaz/log.h> rather than <log.h>.
1766 The YAZ include path (-I ..) is therefore the same as before. Programmers
1767 should update their #include statements or use -Ipath/include/yaz
1768 instead. The main motivation for doing this change is that YAZ header files
1769 can be installed in "standard" locations /usr/include,/usr/local/include
1770 without introducing conflicts, since ALL YAZ header files are stored
1771 in subdirectory yaz (under /usr/include for example).
1773 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1774 rather than project/workspace files. We switched because project files
1775 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1778 Changed name of logging function, logf, to yaz_log, to prevent name
1779 clash with some math-log functions. The YAZ header log.h defines logf
1780 to yaz_log (#define) so there should be no incompatibilities by this
1783 Added bend_start/bend_stop handlers for server. These handler are
1784 called on start/stop of server. For windows they are called whenever
1785 a service is started/stopped.
1787 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1788 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1789 in util/yc.tcl. The auto-generated C code structures are, in a few
1790 cases, incompatible with the old decoders. There are differences in the
1791 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1792 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1793 The preprocessor variable ASN_COMPILED is defined when the compiled
1794 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1795 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1796 wish to use the old encoders/decoders you can specify --disable-yc
1799 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1800 version so that it supports both new - and old version of DB Update
1802 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1803 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1804 change. The name parameter can be set to 0 in which no name is specified
1805 for the construction. The macros odr_implicit and odr_explicit sets name
1806 parameter to zero for the construction involved. New macros
1807 odr_implicit_tag and odr_explicit_tag are similar to the others,
1808 except that a name parameter is added. For programmers' that don't use
1809 ODR they probably only need to change the call to z_APDU and z_External.
1811 Added access control facility by interfacing the TCP wrapper library.
1812 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1813 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1814 name of the daemon and enables the access control as specified in
1815 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1817 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1818 den Dool <H.M.vdnDool@kub.nl>.
1820 Added reference ID parameter to most functions in server API - refer
1821 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1823 Changed name of ccl library to libccl.a (was ccl.a).
1825 Fixed bug in decoder for Explain (Category TargetInfo).
1827 Added support for GNU readline in client. Thanks to Jacob Poulsen
1828 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1830 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1831 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1832 IMPLEMENTATION! This change was made to the development version before
1833 the ZIG decided to retract the amendment. If any users MUST be
1834 compatible with the original Update definition, PLEASE CONTACT US, and
1835 we will include a separate definition corresponding to the old Update
1836 ES. Note that because of the change to the ASN.1 of the
1837 TaskPackageRecordStructure we cannot define a single structure that
1838 will support both versions.
1840 * Added const modifier to buffer parameter for some ODR/BER encoding
1841 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1842 completeWAIS, odr_dumpBER.
1844 Fixed bug in client.c which caused a crash when a scanResponse didn't
1845 contain positionOfTerm.
1847 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1848 * will cause an error in a client if a non-YAZ target sends both a
1849 * list of Scan entries and non-surrogate diagnostics.
1851 Retrieval module enhancements. Tag sets may be typed in the reference
1852 to it. From the .abs-file the "tagset" directive takes a third optional
1853 integer type for the tag set referenced. From a .tag-file the "include"
1854 directive takes a third optional type as well. The old "type" directive
1855 in the tag set itself is still recognized but acts as the default type
1858 Backend interface change. Individual Scan terms returned from bend_scan
1859 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1860 in include/backend.h.
1862 Retrieval module enhancements. Multiple tag sets and attribute sets may
1863 be specified in abstract syntax specs. Revised the error/warning for
1864 logging messages reported by the retrieval module when reading the
1867 Object Identifier system (oid_..) changed. The API is backwards
1868 compatible but the oid-routines now allocates new OID's when needed.
1869 Raw OID's may be specified in oid_getvalbyname.
1871 YAZ now uses GNU configure to generate Makefile(s).
1873 * Minor changes in some of the member names of DeleteResultSetRequest and
1874 DeleteResultSetResponse. See include/proto.h.
1876 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1877 and added member 'languages' in TargetInfo (which was missing).
1879 Changed the way attribute sets are handled in the retrieval
1880 module. These are now cached, just like the abstract syntaxes
1883 Changed YAZ so that it links with compiled ASN.1.
1885 Added Explain-schema definitions and mapping routines. The following
1886 Explain categories have been implemented: AttributeDetails,
1887 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1889 Fixed minor bug in Windows version of Server Library.
1891 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1893 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1895 Added EXTERNAL: UNIverse Resource Report (non-standard).
1897 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1898 ENUMERATED and SET OF.
1900 * Added 'const' to some of the char pointer arguments for the
1901 functions, data1_read_node, data1_getelementbytagname,
1902 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1905 Fixed bug in data1_insert_taggeddata - the last_child member of
1906 parent wasn't initialised.
1908 * Changed data1_read_record and data1_read_node so that the supplied
1909 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1910 doesn't refer to any parts of the "SGML"-buffer.
1912 Fixed bug in server library (Windows version of statserv_remove).
1914 * Changed code so that it compiles as C++. The type definition
1915 of Odr_fun which is a member of Odr_arm was changed. The result is,
1916 that an explicit typecast is needed for the fun pointer when
1917 using Odr_arm - as in:
1918 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1920 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1922 Implemented the new structured date and time definition as approved
1923 by the ZIG. Added schemaId element to the specificTag in Espec-1
1924 (also approved at the last ZIG). Thanks to RVDM.
1926 Added some Object identifiers (RVDM).
1928 Changed the Update Extended Service (RVDM).
1930 Added command "refid" to client which specifies referenceId for
1931 the following requests.
1933 Implemented extended service handling for server. See ztest.c
1934 for an example as well as backend.h. New handlers are registerd
1935 in the Init handler.
1937 * Changed interface for sort in server.
1939 Added new members to statserv_options_block. It allows a server
1940 to read options from another source than just the command line. Thanks
1941 to Charles Woodfield.
1943 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1944 renamed to zboolean. Some C++ compilers complained about the name.
1946 Minor changes to gils.abs. Added index 's' (sort) on title
1947 and date/time-last-modified.
1949 --- 1.4pl2 1998/1/30
1951 Fixed bug in server library regarding inetd mode (-i). This bug
1952 was introduced by release 1.4.
1954 --- 1.4pl1 1998/1/29
1956 Added sort facility in client and backend server interface.
1958 Fixed problem with dependencies in Makefile(s).
1960 Fixed bugs for encoders/decoders of extended services and
1963 Implemented sub-tree feature for schemas. Sub-trees are
1964 referenced in *.abs-files. See explain.abs for an example
1965 of the use of this feature.
1967 Modified bib1.att; local attributes for ANY didn't include
1968 ANY itself (only affects use of the retrieval module).
1970 Fixed bug in plain SGML reader in function data1_read_node:
1971 tags with prefix "var" was incorrectly interpreted as variants.
1973 Added feature "sub-schemas" to enable references to - and definitions
1974 of - group of elements.
1976 * Removed member parent from type data1_element (in data1.h).
1978 Implemented function odr_nullval() that returns the value of
1981 * Removed member num_children from data1_node (in data1.h).
1983 Made NT service interface part of the server library. The
1984 function statserv_main uses the NT service when required and
1985 calls the statserv_start / statserv_close routines.
1987 Routine zget_SearchRequest and zget_PresentRequest fills
1988 resultSetName/Id member with "default" instead of "Default".
1990 Fixed memory leak in server. Request queue member wasn't freed.
1992 Fixed nmem_exit so that memory is freed.
1996 Revised the CCL parser utility to be thread safe.
1998 Added function, oid_ent_to_oid, to replace the function
1999 oid_getoidbyent, which is not thread safe.
2001 * Added nmem_init and nmem_exit to initialize and release
2002 NMEM resources. Function nmem_init should be called once in the
2003 initial thread before NMEM/ODR is used. statserv.c and client.c
2004 have been changed accordingly. The change was necessary to make
2005 NMEM thread safe. The NMEM memory pool is shared amongst threads
2006 in a process. Unix-based applications will still work fine without
2009 Added NT Services interface for the the Z39.50 (statserv) Server.
2010 Refer to the ztest.c source on the usage.
2012 Windows 95/NT port using MSVC5.0. Project files are included in the
2015 * Defined new 'global' handle for the retrieval (data1) system. The
2016 new handled, data1_handle, describes the state of the data1 system.
2017 This handle is passed as first argument to virtually all
2018 data1 related routines. The functions data1_create and data1_destroy
2019 creates and destroys a data1 handle respectively.
2021 Added ODR encode stream member to all backend request structures
2022 init, search, scan etc. This stream should be used to allocate all
2023 memory used for the response when thread safe operation is needed.
2025 Changed the comstack utility, cs_addstr, to be thread safe. The
2026 returned hostname string returned by the function is now part the
2029 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2030 function. The cs_straddr takes a COMSTACK handle as argument, so this
2031 function must be used after cs_create and before bind/connect.
2032 This function is thread safe.
2034 Moved test server to 'ztest' directory - generic server code still
2035 in 'server' directory.
2037 Made prefix query (pquery.c) utility thread safe.
2039 Added new function modifier YAZ_EXPORT to 'export' public DLL
2040 functions when using windows (see include/yconfig.h).
2042 Added definitions to the OID database (util/oid.c) (RVDM).
2044 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2046 Added call to ccl_rpn_delete in client program.
2048 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2049 release of RPN structure.
2051 Added support for C++, headers uses extern "C" for public definitions.
2052 With input from RVDM.
2054 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2055 Thanks to Ronald van der Meer (RVDM).
2057 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2059 Added support for private extensions to the OID database
2060 (oid_setprivateoids()). Thanks to RVDM.
2062 Added optional, physical ANY (key replication)
2064 Fixed null-reference problem in GRS-1 output filter.
2066 Proximity operator added to Prefix Query Format (PQF).
2068 In test client command "base" accepts multiple databases.
2070 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2074 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2076 Smallish bug-fixes in the new encoders/decoders (explain).
2078 Bug fixed in DeleteRequest.
2080 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2082 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2084 Added SOIF syntax (using private OID for now) to retrieval module and client.
2086 Added Update extended service.
2088 Added SearchResult-1 additional info structure.
2090 Added optional CCL (ISO8777) interpreter as separate module. Available
2093 --- 1.2 1996/6/10 (1st anniversary release)
2095 Added Summary record syntax. Lightly tested.
2097 Added OPAC record syntax. Untested.
2099 Added ResourceReport service encoders/decoders. Untested.
2101 Fixed bug in z_Unit - wrong tagging on unitSystem.
2103 Fixed bug in the DiagRecs decoder.
2105 Added options for max PDU size and session timeout to frontend-server.
2107 Added documentation of query-language parsers and other supporting utilities.
2109 [frontend-server] Added Attribute set to the bend_scanrequest API.
2111 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2112 surrogate diagnostics were generated.
2114 [retrieval] Allow multiple local values for attribute.
2116 [retrieval] Allow multiple attributes per element in .abs files. index type.
2118 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2120 --- 1.1pl2 1996/4/10
2122 Minor changes, mostly specific to Zebra's requirements (retrieval)
2126 Repaired bug in frontend server when running multiple listening
2127 endpoints in dynamic mode.
2129 z_External() now won't break if a known, ASN.1 value comes encapsulated
2130 in an octet-string. The value will pass through unmodified in an Odr_oct.
2132 Added a bit of code to the demo client to decode & display
2133 ASN.1-structured records represented in the octet-aligned branch of
2134 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2136 Added z_ext_getentbyref() to the ASN module. Doc updated.
2138 * Completed the SCAN definition in the ASN module. This may break SCAN
2139 code based on older YAZ-versions at compile-time. The fix is easy -
2142 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2143 under the SCAN definition. Remember to initialize this, server-people.
2145 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2146 that this does not extend to ODR and ASN.
2148 Comstack allows insertion of established socket (primarily for
2149 inetd-operation of servers). Doc updated.
2151 Front-end server can now start from the inetd in TCP mode. Doc
2154 --- 1.0pl4 1996/1/24
2158 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2159 the rank and record number.
2161 Adjustments to the frontend server.
2163 Fixed diagnostic BER dumper. It ignored the file argument.
2167 Various changes to retrieval module.
2169 Changed the union discriminators of the protocol files from enums to
2170 ints paired with #defines.
2172 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2175 *Changed operator in the RPN structure to 'roperator', again to avoid a
2178 Fixed problems in Explain decoders/encoders.
2180 --- 1.0pl2 1995/12/6
2182 Memory bug in log module fixed.
2184 --- 1.0pl1 1995/12/5
2186 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2188 Bug in Explain DatabaseInfo module fixed.
2190 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2194 The shift to v1.0 signals that we now consider the *core* functionality
2195 of YAZ reasonably stable (the core being more or less equivalent to
2196 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2197 tested (Explain not at all - though that will happen soonish).
2199 Minor changes to code to support Windows port.
2201 Various minor changes after we're getting to use GRS-1 & co. more.
2203 Added Espec-1 format.
2205 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2206 of the protocol and it cannot be selected when encoding (maps into 'string'
2207 when decoding). Needed to talk to some servers.
2209 Demo client can request simple element set names.
2211 Added Diagnostic Format encoders/decoders.
2213 Added simple Close handling to frontend server (no hooks for resource
2214 reporting yet), and demonstration client.
2216 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2218 --- 1.0b3 1995/08/24
2220 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2221 handled incorrectly when records were requested in the searchResponse. This
2222 will only affect you if you use the frontend-server.
2224 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2225 Test-client will ask for and print GRS1. Ztest will return dummy records
2228 Added Explain encoders/decoders to the service-level API. Untested.
2230 Added Extended Services: Item Order encoders and decoders to the Service-
2231 level API. Untested. We could use a recent copy of the pertinent bits
2232 of the ILL protocol to add those bits.
2234 Added diagnostic format 1 encoders/decoders to the service-level API.
2237 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2238 odr_cons.c, which causes a more correct output.
2240 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2241 was always set to 0 when no records were requested in the searchRequest.
2243 * Added better external-handling. This shouldn't harm old code that
2244 *encodes* externals. It can break code that looks for a
2245 'single-ASN1-type' representation, since those types that are known
2246 are now decoded immediately. Look at the SUTRS sample code in
2247 seshigh.c and client.c. Documentation updated.
2249 Handling of structured records in bend_fetchresponse. Length -1 marks
2250 structured record, type is deduced from format field.
2252 --- 1.0b2 1995/06/27
2253 Fairly quick maintenance release to add SUTRS support.
2255 Fixed handling of SUTRS records in the demonstration client.
2257 * Added format field to the bend_fetchrequest and bend_fetchresponce
2258 structures of the backend API (frontend server). When the record is
2259 returned, the value of the format field is mapped to an OID. The
2260 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2261 of the record. The special value VAL_NONE in the bend_request means
2262 that no specific format was requested by the client. Documentation
2263 updated accordingly. Test server (ztest) will return a fixed dummy
2264 SUTRS record if your client requests SUTRS.
2266 Documentation updated accordingly.
2268 You can now set external libraries and RANLIB support in the top-level
2272 First public release.
