3 Added yaz_poll which is a wrapper for select/poll. When poll is available
4 and non-buggy, it is used, by yaz_poll . This allows more than 1024
7 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
8 functionality through an XML based configuration (ICU chain). This system
9 is useful for search facilities such as Pazpar2 and Zebra that needs to
10 perform tokenization of indexed material. The ICU code in a separate
11 library libyaz3_icu.a.
13 Added HTTP tunnel facility for COMSTACK, bug #1752.
14 This is a facility that allows a Web proxy, such as squid, to tunnel
15 Z39.50 traffic. This facility is "transparent" to must applications
16 using YAZ. It's enabled by using pseudo transport connect: followed by
17 the proxy address, followed by command, then follwed by he regular
18 "virtual" addresss. For example,
19 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
21 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
25 Fixed bad memory reference in ZOOM_record - cuased by member not being
26 initialized. This was a problem only in YAZ 3.0.12.
28 Fixed bug in conversion from MARC to XML: Non-XML characters in control
29 fields were not removed.
31 Changed the way C code is generated from codetables.xml. Made a MARC-8
32 conversion trie for each characterSet section rather than codeTable.
33 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
34 of codetables.xml from Larry Dixson, LOC. Bug #1464.
38 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
39 from ZOOM_record_error).
41 ZOOM C function ZOOM_record_get returns record schema for type="schema".
43 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
45 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
47 Better SRW-to-Bib-1 diagnostic mapping.
49 ZOOM C and yaz-client announces SRU version 1.2 by default.
51 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
54 Fixed in yaz_sru_decode to allow other version than 1.1.
58 Added support for SRU scan for ZOOM.
60 Added support for the use of the older versions or Extended Service
61 Update in ZOOM. To faciliate this, an option "updateVersion" may be
62 set to the version , 1=first, 2=second, 3=third. The third version is
63 what ZOOM C has used so far. And that, obviously, is the default.
65 Added support for CCL queries in Z39.50 queries sent to the GFS (and
66 therefore in Zebra and in SimpleServer-based applications). The new
67 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
68 qualifier file used to transform incoming CCL queries into Type-1 RPN,
69 which is passed into the back-end search callback function.
71 Added support for HTTP Basic authentication in clients: the SRU/W
72 codec encodes the username/password elements of the PDU structure
73 appropriately, and these may be set using the "user" and "password"
74 options in ZOOM-C applications (the same options that are used for
75 Z39.50 authentication).
79 Fixed bug #1208: SSL appears to be broken in ZOOM.
81 Fixed bug #1206: Libxml2 include path weirdness.
83 Added oid_name_to_dotstring.
85 Allow elementSetName to be specified for ZOOM C record update.
87 Allow waitAction to be specified for ZOOM C based for Extended Services.
89 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
90 syntax OID. Bug introduced in YAZ 3 series.
92 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
96 Fixed bug #1157: yaz-client does not read .yazclientrc from current
97 directory. yaz-client now reads commands from file given by option -f
98 if specified; then tries to read .yazclientrc in current directory.
99 Failing that, it reads .yazclientrc from user's home directory.
101 Added support for correlationInfo Note and ID for Record Update via
104 Added yaz-client command querycharset which specifies character set for
105 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
106 (termListAndStartPoint).
108 Charset ISO5428:1984 is an alias for ISO5428-1984.
110 Implemented a way to perform scan in a result set using Z39.50. This
111 is achieved by attaching the result set name in the characterInfo
112 (type InternationalString) of OtherInformation in the Scan Request PDU.
113 The result set is identified in the otherinformation by the new OID:
114 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
115 This allows for scan in result set and faceted search . Zebra did some
116 of this in the APT term using attribute type 8 and value being result
117 set. Using the OtherInformation approach for this is cleaner and easier
118 to work with in proxies and the like. This facility can be used in
119 yaz-client using new command setscan which takes a result set as first
120 argument, start position (APT) as second.
122 Changed decoding of SRU XML packed records to deal with servers that
123 have recordData with XML data with multiple root nodes. Also make
124 comparison for recordPacking case insensitive. Again, one server
125 returns "XML" where others return "xml".
127 For SRU responses allow Content-Type application/xml as well as text/xml.
131 Fixed bug in character set conversion of BER strings. Bug introduced
136 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
138 For OID class, use oid_class consistently.
140 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
143 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
144 character set for bibliographic information interchange". By Giannis Kosmas.
146 Added documentation on new OID API.
150 Changes to generic frontend server interface: added new member
151 'query_charset' for bend_initrequest structure. A backend init handler
152 should set this member to its native character set for query terms.
153 When defined, the frontend server logic will announce this character set
154 to a client if the negotiationModel bit is set by the client. All server
155 implementors are encouraged to specify this. If a backend server does not
156 specify this a warning is issued using yaz_log(YLOG_WARN,..).
158 Added CCL utility to remove terms (stop words) from resulting RPN
159 tree. This is handled by functions with prefix ccl_stop_words_ .
161 New ZOOM C option, "rpnCharset", which allows client-side conversion of
162 terms in RPN queries.
164 Clean-up the CCL API. Moved some internal structures from ccl.h to
165 private header cclp.h. Changed ccl_parser_create so that a Bibset must
166 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
167 This is replaced by ccl_parser_find_str which takes a string instead.
169 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
170 libyaz.la is the core of YAZ except the generic frontend server and
171 does not depend on POSIX threads anymore. libyaz_server.la is the
172 generic frontend server facilities and uses POSIX thread functionality
173 if available. The libyaz.la no longer depends on POSIX threads because
174 the number of global structures is limited. NMEM no longer re-uses blocks
175 between threads ; it simply free's memory immediately but allocates in
176 "large" chunks as usual. We don't expect any performance penalties
177 because of this. The yaz_log system is still using a global log_level so
178 caution must be taken when modifying it with yaz_log_init_.. +
179 yaz_log_mask_str. This, however, should not cause any trouble because
180 these functions are called during initialization of application code
181 anyway. `yaz-config --libs server` returns libs for server applications;
182 `yaz-config --libs` returns libs for non-server applications.
184 New OID database - with public definitions in oid_db.h. Removed old OID
185 database including the head oid.h and definitions such as enum oid_value
186 and struct oident. The new OID database uses the same string names as
187 before but the 'protocol' is gone. There are now only two representations
188 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
189 converts from string to OID; functions with prefix yaz_oid_to_string
190 converts the other way.
192 Change to emit_term() in CQL-to-PQF query translation: when a term has
193 the /regexp relation modifier, do not process it for leading and
194 trailing "^" and "*", which have quite different meanings in regular
197 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
198 write handlers no longer carries a 'last' parameter. This will make
199 yaz_iconv flush "less" characters. A flush is performed by call to
200 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
202 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
203 removed, because function yaz_query_to_wrbuf does the same.
205 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
206 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
208 Deprecated MARC utility functions removed.
210 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
213 Branch split: YAZ_2_1_55_branch
215 --- 2.1.54 2007/03/16
217 Fix to ZOOM-C so that transparent reconnection is properly handled on
218 connections that are in asynchronous mode.
220 Fixed compilation on OpenBSD 4.0.
222 Large strings in GRS-1 records are now properly displayed in yaz-client.
224 Added character conversion support for "advancegreek"; based on patch from
227 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
228 sequence is met. Before the error was not set so it would be unknown.
230 Adjust yaz-marcdump MARC reader so that it skips until record separator
233 --- 2.1.52 2007/03/07
235 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
236 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
237 fd_set structure used as a bitmask for the FDs to be selected on.
239 Using ACX_PTHREAD macro to check for POSIX threads.
241 Fixed have-vsnprintf check.
243 --- 2.1.50 2007/02/23
245 Fixes for configure on BSD. Bug #900.
247 Added snprintf/vsnprintf wrappers for systems that don't have
248 limits (heavens forbid).
250 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
251 created before all previous tasks were completed and removed from the
252 task queue, the new task could be removed by a mistake.
254 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
256 Implemented pass-through CQL-to-PQF conversions. Bug #861.
258 Fixed bug #832: Problem with MARC/charset in yaz-client.
260 Fixed bug #668: save command line history for yaz-client.
262 Fixed bug #830: pkg-config support.
264 --- 2.1.48 2007/01/23
266 Extended ZOOM result set options with two options that may be read by
267 a client: resultSetStatus and presentStatus with values as specified for
269 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
271 Fixed bug #827: Using SSL fails on Debian etch.
273 Fixed bug #826: Weird looking chars for set of MARC records.
275 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
276 that is treated as an ItemOrder with itemRequest being an XML document
277 external. The value of "doc" is the content.
279 Extended the GFS search facility. New member of bend_search_rr
280 'estimated_hit_count' signals that hits is known to be an estmate
281 (higher or lower than real hit count). New member 'partial_resultset'
282 signals that the search was partial (hit count is lower or equal than
283 real hit count). For Z39.50, the information is stored in resultSetStatus
284 member of SearchResponse APDU. For SRU, the information is signalled
285 via SRU diagnostic 59: "Result set created with valid partial results
288 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
290 --- 2.1.46 2007/01/13
292 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
294 Added ZOOM_connection_peek_event.
296 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
297 the following new functions:
298 ZOOM_event_nonblock, ZOOM_connection_process,
299 ZOOM_connection_get_{socket,mask,timeout},
300 ZOOM_connection_fire_event_{timeout,socket}.
301 The existing blocking event handler, ZOOM_event, is a wrapper for the
302 + blocking ZOOM_event_sys_{poll,select}.
304 Implemented function ccl_xml_config which parses XML version of CCL
305 configuration (bug #798).
307 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
309 Added timings utility (yaz/timing.h)
311 --- 2.1.44 2007/01/03
313 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
316 Fixed bug #779: Rotation of apdu.log fails.
318 Fixed for character set conversions:
319 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
320 Honor G1 set in MARC-8 decoding.
322 --- 2.1.42 2006/12/17
324 Fixed bug #775: char conversion does not handle Alternative UTF-8
327 Implemented function yaz_marc_read_line which parses MARC line format
328 records. There is a wealth of formats out there. So far, this function
329 reads line records produced by yaz_marc_write_line.
331 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
332 more generic and easier to remember(!) options: -i format and -o format
333 which specifies input format and output format respectively - where
334 format is one of "marc", "marcxml", "line", "marcxchange".
336 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
337 does not print anything except warnings for records.
339 For yaz-marcdump, added support for MARC split into files (-s) with a given
342 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
343 spec, at http://www.loc.gov/standards/sru/record-update/
344 This has changed the binary layout of the following structs:
345 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
346 bend_update_rr . Patch by Ko van der Sloot.
348 Added GFS utility function bend_assoc_is_alive which returns 1 if
349 association is still alive (client is connected); 0 otherwise (client
350 closed connection). This allows busy servers to stop working for
353 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
354 been a separate piece of software. This version of ziffy has been modified
355 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
357 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
359 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
360 Client code may now interrogate options such as "init_opt_sort" to
361 find out whether the server claims to support various options.
363 --- 2.1.40 2006/11/27
365 Added utilities yaz_{set,get}_esn to set/get element set name from
368 Removed the build of libyazthread.la. The libyaz.so is the threaded version
369 of YAZ and has been so since YAZ 2.1.10.
371 Implemented ZOOM_record_error which returns error information for
372 record (surrogate diagnostic).
374 --- 2.1.38 2006/10/31
376 Updates for SRU Update by Ko van der Sloot:
377 1. Changed name from "operation" to "action"
378 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
379 versions in the code, marked as 'backward compatible'.
380 3. Added diagnostics for SRU Update.
382 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
384 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
386 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
388 For GFS, fixed problem with SRU diagnostic 'First record position out of
389 range' being issued for 0 hits.
391 zoomtst10 part of Windows Build.
393 --- 2.1.36 2006/10/13
395 Implemented yaz_filepath_comp which splits a path into file path
396 components (required by Zebra 2.0.3+).
398 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
399 BSD inspired license until now so this should not have any real impact on
400 anybody. See http://www.opensource.org/licenses/bsd-license.php
402 Fixed bug #687: Missing log lines.
404 Fixed bug #678: CQL to PQF translation does not preserve double-quote
407 Fixed bug #689: SRU diagnostics to be added.
409 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
410 whether a connection is idle (no more work do do).
412 --- 2.1.34 2006/10/04
414 Change type of optval from long to int for invocation of setsockopt with
415 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
417 Added support for specifying the max log file size for the Generic
418 Frontend Server. The size is given with option -r.
420 --- 2.1.32 2006/09/21
422 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
424 --- 2.1.30 2006/09/17
426 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
429 Fixed bug in Generic Frontend Server that could cause a server to stop
430 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
432 For the generic frontend server, the maximum record size is used as maximum
433 size of incoming packages (SRU + Z39.50). The value until was previously
434 only used in Z39.50 Init negotiation and, later, in a session controlled
435 sizes of records returned. This is controlled using -k option. It can be
436 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
438 --- 2.1.28 2006/09/04
440 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
443 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
445 New option for yaz-marcdump -lpos=value which allows setting a portion
446 of MARC header to a certain value.
448 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
450 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
451 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
453 --- 2.1.26 2006/08/15
455 Fixed problem with SRU mode type (soap, get, post) for yaz-client
458 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
460 --- 2.1.24 2006/08/08
462 Fixed MARC ISO2709 encoding routines to deal with character set
465 Minor changes to GFS logging. Database included in search request log
468 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
469 cached/multiple records.
471 Shared libraries are built by default on Unix+configure.
473 Changed cql2pqf transformation to use a different evaluation order. The
474 new order is: always, relation, structure, position, truncation, index
475 and relationModifier. Old order was: always, relation, relationModifier,
476 structure, index, position, truncation. Note that the the latter ones
477 override former ones for identical attributes.. The new scheme means that
478 it is possible to override any existing attribute with a relationModifier.
479 And also that it is possible to override everything for the index rule
480 (except the ones listed in relationModifier). No order is perfect but this
481 one, we believe, covers more real cases.. The "always" should have been
482 called "default", since the attributes there can be overridden with all
485 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
486 compilation phase, but also for yaz-config --cflags output. This allows
487 us to have public headers with Libxml2 stuff in them . It should also,
488 eventually, make Libxml2 checks redundant in packages using YAZ, such
491 --- 2.1.22 2006/06/15
493 Changed SRU update structure bend_update_rr so that SRU diagnostics are
494 stored in uri, message and details.. Previously diagnostics were stored
495 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
496 compatibility.. but he's probably the only one affected, so.
498 Added support for CCL, compiled on the client side, in ZOOM-C. This
499 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
500 input; the resulting query objects can be used for for searching with
501 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
503 YAZ' configure searches for OpenSSL by default.
505 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
506 SL_CTX_use_certificate_file. See
507 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
508 for more info. Thanks to Ko van der Sloot.
510 --- 2.1.20 2006/06/02
512 Bug #600: SRU GET, POST support for yaz-client. Introduced
513 command 'sru' which selects method SOAP/GET/POST.
515 Allow missingValueAction to be specified for the sortspec string -
516 function yaz_sort_spec. By default, the missing value action is null.
517 Use ! to specify "abort". Use = followed by stringvalue to specify default
520 Ensured that Present-handler (if defined) is called in GFS before any call to
521 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
522 searchRetrieve requests.
524 Documentation for YAZ is now based on the Docbook XML/XSLT using
525 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
526 is no longer depending on jade/openjade or docbook-to-man scripts.
527 PDF is no longer part of the distribution - but can optionally be
528 made using DSSSL/jadetex or FOP.
530 Added retrieval handling support in Generic Frontend Server to support
531 conversion between MARC/XML as well as XSLTtransforms. See
532 etc/yazgfs.xml for an example.
534 Added Authentication support to Generic Frontend Server in SRU
535 mode. Authentication using HTTP Basic is supported, as is the use
536 of 'x-username' and 'x-password' parameters in the request itself.
538 Added support for a new character set MARC8s identical to MARC8 except
539 that it converts combined characters to single Unicode characters in the
540 Latin-1 range (when possible).
542 --- 2.1.18 2006/04/24
544 ASN.1 compiler 0.4: generates brief Doxygen file header for
545 generated .h/.c files.
547 Utility yaz_iconv now supports conversion to MARC-8.
549 New facilities for the MARC module. The reading - and writing of
550 content are separate methods for the yaz_marc_t handle. The following
551 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
552 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
553 format). Write functions have prefix yaz_marc_write_.. The existing
554 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
555 available. Removed support for OAI-MARC and simplexml (not the
556 simplexml from PHP5).
558 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
559 to be returned for this connection.
561 --- 2.1.16 2006/03/31
563 Allow multiple languages and charsets to be specified with
564 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
565 negcharset iso-8859-1,utf-8
567 Translation of proximity nodes from CQL into PQF now works.
569 Moved to automake 1.8, 1.9.
571 Added function yaz_log_set_handler which allows a log handler to be
572 installed. This handler will be called for all log messages. Output
573 to file is also produced; but that can be disabled by passing NULL
574 fname to yaz_log_init_file.
576 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
578 For SRW (including GFS), accept application/soap+xml as content-type
581 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
582 produces NO stylesheet reference even if a default stylesheet is specified
585 --- 2.1.14 2006/03/14
587 Updated Windows package to include yazd.dll + yazd.lib for the
588 Development component.
590 If the environment variable YAZ_LOG is set, then it is used as a
591 string indicating the default level of logging to use if not
592 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
593 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
594 used as before. So, for example, to omit warnings from YAZ logging,
597 cql_transform() now map structure and other attributes before indexes,
598 so that index-specific structures and other attributes can override
599 defaults. So now a combination of mapping specifications such as:
601 index.dc.date = 1=date-modified 4=5
602 does the right thing.
604 cql_transform() now also respects the "always" mapping specification,
605 which establishes an initial set of attributes to be used for all
606 terms except where overridden by more specific attributes associated
607 with the index, relation or modifier.
609 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
610 which mode to use; one of "post", "get" or "soap" (SRW, default).
612 Fixes for yaz_iconv routines: changed trie-based character set conversions
613 to use only non-negative values for bit fields due to Sun's C compiler not
614 supporting negative values.
616 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
617 sequences where not read correctly. Fix by Rustam Usmanov.
619 Updated win/makefile to use options, settings which makes things
620 compile with VS C 2005.
622 --- 2.1.12 2006/02/01
624 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
626 In ZOOM socket code, use select instead of poll on MacOSX.
628 ZOOM-C now support client-side compilation of CQL into RPN that is
629 sent to the server, enabling CQL to be used against all Z39.50
630 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
631 ZOOM_query object, and submit it using ZOOM_connection_search().
632 The CQL-to-RPN translation uses a configuration file, the name of
633 which must be specified in the Connection's "cqlfile" option.
635 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
636 function, which takes as its start-term parameter a ZOOM_query object
637 (which may have had either CQL or RPN set into it).
640 --- 2.1.10 2005/11/29
642 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
643 GFS to support this as well. Backend handler, bend_srw_update, does the
644 update work. Code contributed by Ko van der Sloot.
646 Allow retrieval of Search Result-1 information in ZOOM by the use of
647 options that are attached to a result set. ZOOM documentation updated
650 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
651 UTF-8 conversion. Patch by Raj Patel.
653 Added option -m to GFS to control formatting of timestamps in log file.
655 Added 'exit' as synonym for 'quit' in yaz-client
657 Added support for specifying SRW resultSetId + resultSetIdleTime in a
658 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
659 for the new members. Patch by Ko van der Sloot.
661 Added support for SRU POST. It is supported for content-type
662 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
664 Do not build the separate Multi-threaded (MT) library libyazthread.la.
665 Instead make the library libyaz.la multi-threaded. Threading as a whole
666 can still be disabled by configure option --disable-threads. Previosly,
667 with older GLIBCs there were problems with MT libs under Apache. This
668 has now been fixed a long time ago.
670 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
673 CQL module modified to be case insensitive for relations/indexes/operations.
675 Fixed bug in CQL transform code: incorrect value relationModifieder
678 Added 'show all' command for yaz-client which retrieves all results
681 Added new yaz-client, xmles, which takes a (private) OID and
682 a document to be sent as an extended service request.
684 Describe new yaz-client commands wait_response and set_auto_wait.
686 Increase TCP/IP listener backlog from 3 (which I am guessing was
687 copied from the SunOS manual entry way back when) so SOMAXCONN, so
688 that the socket will queue as many incoming connections as it's able
689 to handle ongoing connections. In other words, it will never now
690 refuse a connection that it would be able to handle merely because
691 it's not got around to accepting() enough of the pending connections
692 yet. This is the behaviour anyway under Linux, where the listen()
693 argument is ignored; but not under BSD and on systems such as
694 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
695 YAZ-based servers should now be uniform across operating systems in
698 yaz-marcdump uses 64-bit file access on some systems. This is enabled
699 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
700 This allows yaz-marcdump to read large MARC batches (>2 GB).
702 Modified all YAZ source files - except the source which is auto-generated
703 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
706 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
707 corresponding to the existing *_setl() function. These allow option
708 values containing arbitrary valuues.
710 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
711 ZOOM_resultset_sort() in new applications. Its behaviour is identical
712 except that it returns an indicator of whether or not the sort
713 criterion was accepted (0 for OK, -1 for invalid).
717 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
718 MARC output rather than returning "new" buffer.
720 yaz-client warns about unknown init options.
722 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
726 Added support for SRW sort in Generic Frontend Server. Patch
727 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
728 sortKeys - or NULL if none is provided.
730 Fixed bug #307: It was impossible to specify indefinite/no timeout
731 for ZOOM_event. Special timeout value -1 now means indefinite timeout
734 Added support for multiple languages and charsets to be specified in
735 ZOOM. Each charset/language is separated by a blank. If negotiation is
736 in effect in init-response, Option
737 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
738 Code based on patch by Vasiliy Osadchuk.
740 Fixed bug #306: infinite recursion that occurred when calling
741 yaz_log_level_init as the first call (before other log level or
744 Fixed bug in scan handling in front end server: if preferred-Position-In-
745 Response was non-present, a NULL pointer referece was performed.
749 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
750 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
751 now defined for all those error codes. So instead of putting 109 in
752 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
753 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
755 Modified the yaz-marcdump utility to skip garbage bytes between MARC
758 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
760 Program yaz-client now exits and produces an error message if multiple
761 Z39.50 servers are specified on the command line (none or one allowed
764 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
769 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
771 Fixed bug #272: Preserve spacing for CCL terms.
775 Added support for virtual hosts and multiple backend servers for
776 the YAZ frontend server. The configution is XML based and
777 support specificition of CQL to RPN mappings and explain information.
778 See section "Virtual Hosts" in the YAZ manual.
780 Extended OPAC display utility. OPAC display utility renders
781 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
782 to supplement yaz_marc_decode_wrbuf.
784 Fixed a bug in MARC decoder that could caused it to crash for some
785 invalid MARC records. More diagnostics and warnings where added in
786 XML output (warnings, etc are stored in comments).
788 --- 2.0.34 2005/02/08
790 Fixes for UNIX domain sockets. Bug #261.
792 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
794 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
795 Added yaz_marc_subfield_str which defines subfield lead string which is
796 used in YAZ_MARC_LINE format. Default string is blank+$. Added
797 yaz_marc_endline_str which defines end of fields string used in
798 YAZ_MARC_LINE format. Default string is newline.
800 Experimental support for MarcXChange. This format can be produced
801 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
802 http://www.bs.dk/standards/MarcXchange.xsd
804 Added yaz-client commands scansize that sets maximum number of
805 entries to be returned by scan.
807 --- 2.0.32 2005/01/11
809 Added support for SRW scan in yaz-client and Generic Frontend Server.
811 * Added whereInList member to SRW Scan Term.
813 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
815 Fixed NMEM system to return aligned blocks on the smallest boundaries
816 that are suitably aligned for all possible types on the particular
817 architecture YAZ is being built for.
819 --- 2.0.30 2005/01/04
821 Fixed numerious warnings that was issued with newer versions of GCC.
823 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
824 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
827 Make YAZ Generic Frontend Server slightly faster.
829 Enhance (and reduce) logging for Generic Frontend Server.
831 Revert YAZ log system so that it flushes every write operation
832 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
834 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
835 instead of LOG_, due to name clash with syslog(3). LOG_ are still
836 present. New applications should define YAZ_USE_NEW_LOG=1 - this
837 will effectively disable old definitions.
839 --- 2.0.28 2004/11/09
841 Added yaz_log_time_format which specifies log format using
844 Added yaz_log_module_level which returns mask for a module. Value
845 is non-zero mask a if module is enabled; zero if disabled.
847 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
848 in include/yaz/cql.h.
850 Fixed bug #176: Dont throw diagnostics on empty SRU args.
852 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
854 Fixed bug #172: RPM builds does not enable SSL.
856 Doxyfile.in part of dist. Doxyfile generated by configure.
858 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
859 are given and the corresponding component does not exist.
861 Extend CCL documentation in YAZ reference. Describe r=r.
863 --- 2.0.26 2004/10/01
865 Fixed MARC->MARCXML conversion to properly deal with
866 fields, subfields, indicators having non-ASCII characters.
868 Fixed MARC->MARCXML conversion so that ASCII control characters
869 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
872 Added YAZ GFS support for conversion from Z39.50 surrogate
873 diagnostics to SRW surrogate diagnostics.
875 Bug fix: YAZ GFS did not return schema in explainResponse.
877 --- 2.0.25 2004/09/30
879 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
880 now converts recordSchema to elementSetName as well as schema URI.
882 Fixed bug in COMSTACK that prevented HTTP request packages from being
885 --- 2.0.24 2004/09/29
887 Added CCL facility r=r "range" which is similar to r=o "ordered" but
888 does not require white-space before and after the dash in a range, e.g.
889 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
892 Fixed a few AC_TRY_LINK configure tests that did not operate properly
893 due to new GCC removing "redundant" code.
895 Added yaz-client commands scanpos and scanstep that sets preferred
896 position and step-size for scan.
898 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
900 Added CCL utility ccl_qual_buf which parses one or more CCL
901 spec lines in a buffer.
903 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
904 of name and value - ignoring empty lines and comments.
906 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
908 Added odr_get_element_path which returns current element path for an
909 ODR handle. This utility is useful in error handling or user-defined
912 Added ODR_PRINT utility odr_set_stream which is is a more generic
913 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
914 to a write function and pointer to close function. The close function - if
915 non-NULL - will be called during odr_destroy.
917 Fixed bug in CCL parser where truncation char was not removed from
918 right side when truncation=both was in effect.
920 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
923 --- 2.0.23 2004/08/11
925 Fix buffer overrun in CQL parser when dealing with proximity (%).
927 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
928 to UTF-8/UCS conversion is now only based on codetables.xml.
930 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
932 --- 2.0.22 2004/08/06
934 Add support for more "commit changes" in ZOOM (uses Extended Services).
936 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
939 Yet another small fix for configure of SSL.
941 --- 2.0.21 2004/05/14
943 Fix SSL libs for configure when --with-openssl=DIR is given.
945 --- 2.0.20 2004/05/10
947 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
949 SSL comstack now uses yaz.pem certificate file on server side
950 by default. Certificate filename can be configured by calling
951 comstack function cs_set_ssl_certificate_file before cs_bind is used.
953 Fix bug regarding multiple calls to ZOOM_connection_connect.
955 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
957 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
958 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
960 ZOOM now allows inspection of X509 peer certificate for verification.
961 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
963 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
964 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
965 as "modular" but it simplifies things.
967 Added cs_get_peer_certificate to that returns peer X509 PEM.
969 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
970 NULL if SSL is unavailable.
972 Documentation about MARC decoding tools.
974 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
976 --- 2.0.19 2004/03/30
978 Rename CHANGELOG to NEWS to follow GNU style packing.
980 Fix bug with missing initialization of member in init_diagnostics.
981 This bug affects threaded version of GFS server.
983 --- 2.0.18 2004/03/20
985 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
988 Ensure zlib.dll is packed with Windows install.
990 --- 2.0.17 2004/03/17
992 Fix encoding of xsd:string to use text instead of CDATA.
994 Fix endless loop in CQL parser with unbalanced ".
996 Use a more compact way to store MARC-8 conversion tables.
998 --- 2.0.16 2004/03/16 Debian only
1000 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1003 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1008 --- 2.0.15 2004/03/01
1010 Another fix for decoding of XML packed records.
1012 --- 2.0.14 2004/02/25
1014 Fixes for Chunked encoding. White space not ignored after length spec.
1016 Update NS and use default NS for SRW diagnostic elements.
1018 --- 2.0.13 2004/02/23
1020 Implement ZOOM_resultset_cache_reset which resets record cache.
1022 Implement ZOOM_resultset_sort which sorts a result set.
1024 Implement chunked HTTP transfer.
1026 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1028 --- 2.0.12 2004/02/16
1030 Added member 'schema' to bend_explain_rr structure so that backend
1031 can specify explain record identifier. Defaults to Zeerex 2.0.
1033 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1035 --- 2.0.11 2004/02/16
1037 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1040 Added init command for yaz-client which sends "extra" init request.
1042 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1043 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1045 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1047 Make ZOOM error code for "invalid query".
1049 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1051 --- 2.0.10 2004/02/05
1053 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1056 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1058 Added option -p <file> to make Generic Frontend Server to write PID file.
1060 Added option -D to put Generic Frontend Server in background on its own.
1062 Make ZOOM C recognize option "password". If unset, "pass" is used
1063 (for backwards compatibility).
1065 Fixed a bug in Generic Frontend Server that could make it crash if a
1066 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1069 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1070 Must be issued before open, in order to be in effect.
1072 --- 2.0.9-6 2004/01/12 Debian/Windows
1074 Make the SRU server more picky WRT unknown params, etc.
1076 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1078 New YAZ client command, options, that sets Z39.50 options.
1080 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1081 options from a string of tokens (one token for each option bit).
1083 Update SRW diagnostic code messages.
1085 --- 2.0.9-5 2004/01/07 Debian/Windows
1087 Handle user defined stylesheet for SRW/SRU.
1089 --- 2.0.9-4 2004/01/06 Debian/Windows
1091 Fix bug in decoding of Content-Length.
1093 --- 2.0.9-3 2004/01/06 Debian/Windows
1095 Fix a bug with decoding of XML packed records.
1097 --- 2.0.9-2 2004/01/05 Debian only
1099 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1101 Fix bug in SRW/SRU diagnostics decoding.
1103 --- 2.0.9 2004/01/05
1105 Fixed bug in Generic Frontend Server which could drop records exceeding
1106 preferred message size. Reported and fixed by Irina Dijour.
1108 Fixed calculation of package size for structured records in Generic
1109 Frontend Server. Reported and fixed by Irina Dijour.
1111 Fixed namespace for SRW/SRU diagnostics.
1113 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1115 --- 2.0.8 2003/12/22
1117 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1118 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1121 CQL changes to reflect recent changes to the specification:
1122 * Documentation talks about context sets instead of index sets.
1123 * Documentation talks about indexes instead of qualifiers.
1124 * The CQL-to-PQF transformer's configuration file now uses
1125 "index.set.name = <attributes>" instead of the old form
1126 "qualifier.set.name = <attributes>". (Both forms are still
1127 understood but the latter is deprecated.)
1128 * CQL terms with no explicit index specified are now interpreted as
1129 cql.serverChoice instead of srw.serverChoice (which of course
1130 behaves exactly the same.)
1132 --- 2.0.7 2003/12/16
1134 MARC conversion can now generate ISO2709 output in another
1135 character set. yaz-marcdump uses this facility if you invoke it
1138 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1139 functions from there can be used from C++.
1141 --- 2.0.6 2003/12/04
1143 Frontend server now transfers memory from decoded packages to stream
1146 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1147 references to show up.
1149 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1150 the ZOOM Abstract API. The older names for the same options are still
1151 also supported for the benefit of old applications.
1153 ZOOM-C supports "implementationId" and "implementationVersion" options
1154 to go along with "implementationName". These allow the user code to
1155 specify identification strings to be sent to servers.
1156 Add OID for the new ExtLite attribute set.
1158 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1159 as requested/supplid by Ere Maijala <ere@atp.fi>
1161 For generic frontend server, reverse the order of
1162 "toolkit-supplied / application-supplied" strings sent as implementationId,
1163 Name and Version. Also, remove the spaces around the slash. This brings
1164 the GFS in line with the behaviour of ZOOM-C on the client side.
1166 Add function ZOOM_scanset_display_term.
1168 yaz-client shows scan displayTerm if present.
1170 Utility yaz-iconv is now installed by default along with the man page
1173 Extend configure check for OpenSSL to use pkg-config where available (such
1176 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1177 server to specify uid/gid/mask for socket using the format
1178 unix:[user=uid,][group=gid,][umask=mask,]file=path
1179 If file= is omitted the existing format is assumed, e.g.
1181 in which case the mask is 0666 (rw for everybody).
1183 Major restructure of YAZ source. All source in libyaz is in src directory.
1184 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1185 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1187 Added man page for utility yaz-marcdump (used to be called marcdump).
1188 yaz-marcdump is installed by 'make install'.
1190 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1191 of incoming package failed.
1193 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1195 Change prototype of odr_perror: add const to message string.
1197 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1199 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1200 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1201 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1202 DNS lookup. There should not be any compatibility problems with this
1203 assuming that blocking=1 or 0 is used.
1205 Fix bad reference in UNIX comstack in function cs_addrstr.
1207 Fix for compilation on AIX.
1209 The generic front-end server (server/seshigh.c) now supports returning
1210 Init diagnostics to the client in User-information-field, in
1211 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1214 --- 2.0.4 2003/09/04
1216 Allow any CQL relation (not just all,any,exact,scr).
1218 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1219 that features the same UI.
1221 Implemented command update0 in YAZ client which is equivalent to
1222 update but uses old of Ext Update ASN.1.
1224 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1225 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1226 Previously no OID was used for this info.
1228 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1229 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1230 returns 'malformed search term' otherwise.
1232 SortResponse member resultCount now set to NULL in sort handler of
1235 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1238 Add three new utility functions for translating OIDs between various
1239 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1240 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1241 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1242 char *oid_to_dotstring(const int *oid, char *oidbuf);
1243 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1245 Reverted modifications for ES Update definition for z_IU0Update
1246 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1247 is back to YAZ 2.0.2.
1249 String value attributes for CCL parser.
1251 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1252 which their FirstSearch server returns in Init responses, sometimes
1253 carrying useful diagnostic information when Init fails. This has the
1254 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1255 "z39.50/oclcui.asn", where its definition is somewhat different from
1256 what OCLC document on their web-site, as required to interoperate with
1259 Support for anonymous authentication in yaz-client. Use the command
1262 * Fix the OID of the Index Data-local "admin" Extended Service from
1263 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1264 the 1000, which indicates a locally-defined OID, was a mistake.
1266 --- 2.0.3 2003/06/20
1268 Fix CCL directive @case handling so that it affects string match for
1269 both CCL keywords and qualifiers.
1271 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1272 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1273 Decoder has been updated with ASN.1 changes as listed in
1274 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1275 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1276 z_IUUpdate, remains unchanged.
1278 ZOOM_record_get may now return a record in a specific character set.
1279 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1280 "from" is the character set of record as returned by target. "to" is
1281 the character set to be returned. If omitted, "to" is UTF-8.
1283 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1285 New ODR utility, odr_getelement, which returns name of element for
1286 which encoding/decoding failed.
1288 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1289 in cases where a required element was omitted.
1291 Bug fix: some MARC8 sequences were not converted.
1293 New ZOOM option "step" which specifies number of records to be
1294 retrieved in one chunk. Used in conjunction with "start" and "count".
1296 SRW support for yaz-client. Use scheme http: to use it, e.g.
1299 yaz-client no longer does (un)intelligent character set conversions
1300 by default. Can be enabled with charset and marc_charset commands.
1302 xmalloc trace fix for 64-bit systems such as DEC alpha.
1304 Solaris 2.6 compile fix.
1306 New function, cql_strerror() translates SRW error codes, as returned
1307 by cql_transform_error(), into human-readable English strings. Used
1308 in yaz-client diagnostics when appropriate.
1310 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1311 converts it into a type-1 query which is sent to the server. This
1312 makes CQL available for use with all Z-servers, as opposed to the tiny
1313 minority that can handle CQL queries themselves.
1315 --- 2.0.2 2003/04/28
1317 New Debian package layout similar to the Redhat Package layout.
1319 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1320 and search result respectively.
1322 --- 2.0.1 2003/04/25
1324 Redhat package is now several packages: libyaz (runtime libraries),
1325 libyaz-devel (development and documentation, and yaz (utility programs).
1326 Package spec file by Morten Bøgeskov.
1328 New member 'schema' in struct bend_fetch_rr which the name of requested
1329 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1330 handler MAY set this to reflect the schema of the returned record.
1332 New member 'display_term' in struct scan_entry. GFS now sets member entries
1333 and allocates scan entries to be filled by user scan handler. In previous
1334 version, entries member was allocated by the scan handler. That still works,
1335 but the GFS will ignore member display_term - assuming it was NOT set by
1336 the handler. The fact that the GFS now allocates the entries both allows
1337 for new members and makes a scan handler easier to write.
1339 Fix CQL lex buffer overflow.
1341 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1342 SRU default recordPacking is string.
1344 SRU protocol support for frontend server.
1346 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1348 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1350 Added scan for the ZOOM shell (zoomsh).
1354 * String Identifers for Schemas (Amendment 5).
1355 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1356 Old definition for schema
1357 Odr_oid *schema; /* OPT */
1362 Z_InternationalString *uri;
1363 #define Z_Schema_oid 1
1364 #define Z_Schema_uri 2
1367 * resultCount parameter to Sort Response (Amendment 1).
1368 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1370 Support for SRW 1.0 over HTTP. This is an optional feature and
1371 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1374 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1375 on the same port. SRW SearchRetrieveRequests are mapped
1376 to bend_init,bend_search,bend_fetch,bend_close.
1378 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1380 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1381 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1383 ZOOM connections are SRW based if schem http is used for hostname
1384 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1385 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1387 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1388 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1389 distance=n, order=true/false, relation=le, prox unit=word. If
1390 n is omitted, distance 1 is used.
1392 Fixed problem with C compiler include path in wrong order.
1394 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1395 on Solaris. Patch from Ko van der Sloot.
1397 New MARC decode API. All new functions operate on a yaz_marc_t
1398 handle. The most important new functions are: yaz_marc_create,
1399 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1400 decode and destroy respectively. Decoder can produce formats
1401 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1402 include/yaz/marcdisp.h.
1404 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1405 to UTF-8, UCS-32, wchar_t or Latin-1.
1407 * Prototypes for yaz_iconv_-functions moved to separate header
1408 include/yaz/yaz-iconv.h.
1410 Make a few private functions 'static' in unix.c. This prevents
1411 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1413 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1414 are set when Init Response is received.
1416 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1417 but returns diagnostic set as well.
1419 New function yaz_strerror which is a portable wrapper for
1420 strerror/strerror_r/GetLastMessage.
1422 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1423 is returned for MARC. If type is "oai", then OAI MARC is returned.
1425 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1428 --- 1.9.2 2002/11/26
1430 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1432 Fix bad race conditions on SIGTERM and terminate gracefully in
1435 Move retrieval (data1) module to Zebra since nobody seems to be
1438 Add GRS-1 render for ZOOM using same format as yaz-client.
1440 --- 1.9.1 2002/10/05
1442 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1444 Fix broken ESpec handling in data1 module.
1446 SGML reader parses comments and makes them part of the data1 tree.
1448 Added several type casts so that YAZ compiles as C++ code.
1450 ZOOM didn't handle PDU encoding failures properly.
1452 Added more Bib-1 diagnostics (approved extensions).
1454 GNU configure: better check for iconv.
1456 More portable use of accept, getpeername. Check for socklen_t. Use
1457 int/size_t if socklen_t is not defined.
1461 PQF parser rejects bad queries - including those with extra
1462 characters in them. PQF parser used to silently ignore that.
1463 Cleaner API for PQF added, which allows you to get detailed
1464 error information for bad queries (see yaz/pquery.h).
1466 Fixed bug in ZOOM_record_get for type "database".
1468 Implemented mini iconv library supporting conversions between
1469 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1471 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1473 --- 1.8.9 2002/08/20
1475 Fixed ZOOM C record cache so that preferredRecordSyntax and
1476 elementSetName is used to check for already fetched records.
1478 --- 1.8.8 2002/08/02
1480 Added three members in bend_initrequest structure to facilitate
1481 character set negotiation.
1483 Fixed a bug in frontend server that could cause indefinite
1484 loops under rare conditions.
1486 Revised character set utilities (charneg.h) so that encoding
1487 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1489 For PQF, directive @term <type> sets term type for Scan/Search.
1490 Here <type> is general, string, numeric, null. The term type
1491 is inherited - just like @attr.
1493 New call odr_set_charset that sets character set conversion for
1494 international-strings on a ODR stream. Prototype is:
1495 int odr_set_charset(ODR o, const char *to, const char *from);
1496 The InternationalString is still represented as C string in YAZ
1497 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1498 won't). On the protocol level, you can use any encoding.
1500 Support for UNIX sockets in ZOOM.
1502 Solaris recv sometimes returns errno == ENOENT. It is treated as
1503 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1505 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1506 both client and server. Code by Morten Bøgeskov.
1508 --- 1.8.7 2002/05/22
1510 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1511 that they can be used directly from Visual Basic. You must recompile
1512 your windows APP if you're using ZOOM.
1514 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1515 Commands "lang" and "charset" sets language and character set respectively.
1516 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1517 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1519 Attributes from multiple CCL fields may be OR'ed rather than merged
1520 using directive "@field or". Fields are still merged by default -
1521 equivalent to "@field merge".
1523 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1526 Fixed bug in zget for parameter ExtendedServicesResponse.
1530 --- 1.8.6 2002/03/25
1532 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1534 Client displays USR.1:SearchResult-1 (hits per term).
1536 Additional Search Info for search in Generic Frontend Server.
1538 Fixed CCL parsing of "field=s".
1540 WIN32 installer - using the excellent NSIS software from nullsoft.
1542 Fixed CCL parsing of "field = - <number>".
1544 Added function yaz_marc_decode that decodes MARC for line mode
1545 display or XML (similar to that used by JZKit).
1547 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1548 Z39.50. But ISO/ILL was, however.
1550 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1551 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1553 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1554 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1556 --- 1.8.5 2002/02/03
1558 New YAZ client features: Command completion and new commands:
1559 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1560 Code provided by Jacob Poulsen.
1562 New call oid_trav, that visits all registered OIDs via callback.
1564 Function ZOOM_record_get now returns const char pointer rather than
1565 void pointer. It saves a lot of type casts.
1567 For YAZ client, command "auth" now allows you to set authentication
1568 in IdPass style. It is enabled when three tokens are given - order
1569 is user, group and password.
1571 Fix memory leaks in MARC record handling for ZOOM.
1573 New option for YAZ client, -k <kilobytes> that sets
1574 maximum record size. Similar to -k option for generic frontend
1575 server and yaz-ztest.
1577 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1579 Prefix query parser reports "fail" when bad attribute set is given.
1581 Fix in MARC decoder. Proximity logging. Fix for attribute set
1582 in scan handler for server. Patches by Shigeru Ishida.
1584 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1587 Configure option --with-openssl=<dir> now works when a directory is
1588 specified. Patch provided by Morten Bøgeskov.
1590 New option for YAZ client, -u <auth>, that sets authentication.
1592 ZOOM fix: error information was sometimes "missing", since error
1593 was cleared/reset too when it shouldn't.
1595 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1597 --- 1.8.4 2002/01/04
1599 Scan for ZOOM API. New object ZOOM_scanset. New functions
1600 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1601 ZOOM_scanset_destroy.
1603 New ZOOM function, ZOOM_connection_last_event, that returns type
1604 of last event (such as "receive data", "send data", "apdu received",
1607 New ZOOM option, schema, that specifies schema for retrieval.
1609 New CCL feature. Qualifiers can be aliases for one or more
1610 other qualifiers (if more than one is given, OR is used).
1612 ZOOM uses named result sets if target supports it.
1614 Two new YAZ client commands: . (dot, which sources a script of YAZ
1615 client commands), and ! (to execute shell command.). Implemented
1618 Working on Debian packages.
1620 --- 1.8.3 2001/11/19
1622 YAZ client enables named result sets only if target supports it.
1624 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1626 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1627 with key="host" to get same result.
1629 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1630 Function Z3950_resultset_record(s) returns references to records
1631 "owned" by resultset. To become owner use Z3950_record_clone.
1633 Function z_ext_record handles Extended Services. Thanks to
1636 --- 1.8.2 2001/11/12
1638 CCL Parser fix: ignore token comma when dealing with and-lists.
1640 Documentation updates for COMSTACK.
1642 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1643 Changed prototype Z3950_records. For some functions, int parameters
1644 were changed to size_t.
1646 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1649 New MARC decode/display function, marc_display_exl, which properly rejects
1650 non-ISO2709 records. YAZ client uses it.
1652 --- 1.8.1 2001/10/29
1654 Fix bug: local attribute set wasn't set correctly in PQF strings.
1658 * Old Z39.50 codecs no longer supported.
1660 Added ZOOM C binding. See http://zoom.z3950.org/
1662 Renamed states for COMSTACKs to avoid confusion with events.
1664 Implemented cs_look and proper cs_rcvconnect.
1666 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1668 Configure detects POSIX threads on OpenBSD.
1670 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1671 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1673 When error is returned from present handler, non-surrogate diagnostic
1674 is returned in present response (and fetch handler is no longer called).
1676 * Minor adjustments to pquery parser (PQF). Token characters may be
1677 escaped by using backslash (C-style).
1679 PQF parser allows string attribute values to be specified. For @attr,
1680 non-numeric characters after the equal-sign are treated as strings
1681 (e.g. @attr 9=title).
1683 CCL trunction character may be defined (@truncation in file)
1685 * function zget_ExtendedServicesRequest sets waitAction to
1686 waitIfPossible (was wait).
1688 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1691 CCL operator names may be set in field definition files (CCL_bibset).
1692 See ccl/bib1 for an example.
1694 Fixes in ASN.1 compiler for C++ compatibility.
1696 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1697 and "op_or" to avoid conflict with C++.
1699 Fixed problem with GNU readline detection on Redhat 7.0.
1701 Added step-size for Scan backend handler.
1703 Fixed bug that made the frontend server crash when no attribute
1704 set was specified for scan.
1706 Front-end server automatically switches to original working directory
1707 when installed as an NT service. Previously -w had to be specified to
1710 Added extended attributes for retrieval module (data1), so that data1
1711 records carry d1_readXML/SGML attributes. d1_read also supports
1712 null-data rules ( <tag/>)
1714 On UNIX when POSIX threads are available, a separate library libyazthread
1715 is created. Programmers should link with that library and the yaz library
1716 when using threads. The reason for the split was that some applications
1717 on Linux, such as Apache, doesn't work well when using shared objects that
1720 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1721 (or any frontend server) in SSL mode by specifying ssl: followed by
1722 address. Only tested on UNIX.
1724 Added feature for CCL module. Virtual structure s=al or s=ol generates
1725 and-list and or-list respectively instead of phrase search.
1729 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1730 log_mask_str. This was done to avoid name conflicts with other libraries
1731 (such as other PHP extensions).
1733 Added raw OID member for preferred record syntax (request_format_raw)
1734 and returned record syntax (output_format_raw) for backend fetch method.
1736 Config file yaz-config now accepts options so that it returns specific
1737 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1739 Shared library support for UNIX using GNU libtool.
1741 * Modified backend interface. Request/Response struct's replaced by
1742 one read/write C struct. For example bend_fetchrequest and
1743 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1744 Every handler - even search has to be registered in bend_init
1745 handler. This means that the YAZ library no longer refers to
1746 external functions and it makes it possible to make the whole
1747 thing a single DLL/SO.
1749 Added Segment handler for backend server.
1751 Added Zmbol/Zebra administrative functions to YAZ client.
1753 Threaded frontend server on UNIX (when POSIX Threads are available).
1754 Starting the server with option -T enables multi-threading.
1758 Added configure option --enable-comp/disable-comp to control use
1759 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1760 located in sub directory asn.
1762 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1763 in ${exec_prefix}/bin along with the other programs yaz-client and
1766 GNU automake used to maintain makefiles.
1768 Added several OID's.
1770 Changed retrieval module so that we can load records with no abstract
1771 syntax defined. Tagpaths in these records are fully composed of string
1774 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1778 On UNIX, the generated makefile now supports a proper 'make install'.
1779 The prefix can be set via GNU configure to set the install location
1780 (default is /usr/local).
1782 * YAZ programs client and ztest were renamed to yaz-client and
1783 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1784 locations, such as /usr/bin,/usr/local/bin,etc.
1786 * YAZ Header files were moved from include to include/yaz. YAZ Header
1787 files are referred to as include <yaz/log.h> rather than <log.h>.
1788 The YAZ include path (-I ..) is therefore the same as before. Programmers
1789 should update their #include statements or use -Ipath/include/yaz
1790 instead. The main motivation for doing this change is that YAZ header files
1791 can be installed in "standard" locations /usr/include,/usr/local/include
1792 without introducing conflicts, since ALL YAZ header files are stored
1793 in subdirectory yaz (under /usr/include for example).
1795 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1796 rather than project/workspace files. We switched because project files
1797 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1800 Changed name of logging function, logf, to yaz_log, to prevent name
1801 clash with some math-log functions. The YAZ header log.h defines logf
1802 to yaz_log (#define) so there should be no incompatibilities by this
1805 Added bend_start/bend_stop handlers for server. These handler are
1806 called on start/stop of server. For windows they are called whenever
1807 a service is started/stopped.
1809 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1810 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1811 in util/yc.tcl. The auto-generated C code structures are, in a few
1812 cases, incompatible with the old decoders. There are differences in the
1813 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1814 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1815 The preprocessor variable ASN_COMPILED is defined when the compiled
1816 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1817 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1818 wish to use the old encoders/decoders you can specify --disable-yc
1821 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1822 version so that it supports both new - and old version of DB Update
1824 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1825 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1826 change. The name parameter can be set to 0 in which no name is specified
1827 for the construction. The macros odr_implicit and odr_explicit sets name
1828 parameter to zero for the construction involved. New macros
1829 odr_implicit_tag and odr_explicit_tag are similar to the others,
1830 except that a name parameter is added. For programmers' that don't use
1831 ODR they probably only need to change the call to z_APDU and z_External.
1833 Added access control facility by interfacing the TCP wrapper library.
1834 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1835 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1836 name of the daemon and enables the access control as specified in
1837 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1839 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1840 den Dool <H.M.vdnDool@kub.nl>.
1842 Added reference ID parameter to most functions in server API - refer
1843 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1845 Changed name of ccl library to libccl.a (was ccl.a).
1847 Fixed bug in decoder for Explain (Category TargetInfo).
1849 Added support for GNU readline in client. Thanks to Jacob Poulsen
1850 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1852 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1853 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1854 IMPLEMENTATION! This change was made to the development version before
1855 the ZIG decided to retract the amendment. If any users MUST be
1856 compatible with the original Update definition, PLEASE CONTACT US, and
1857 we will include a separate definition corresponding to the old Update
1858 ES. Note that because of the change to the ASN.1 of the
1859 TaskPackageRecordStructure we cannot define a single structure that
1860 will support both versions.
1862 * Added const modifier to buffer parameter for some ODR/BER encoding
1863 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1864 completeWAIS, odr_dumpBER.
1866 Fixed bug in client.c which caused a crash when a scanResponse didn't
1867 contain positionOfTerm.
1869 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1870 * will cause an error in a client if a non-YAZ target sends both a
1871 * list of Scan entries and non-surrogate diagnostics.
1873 Retrieval module enhancements. Tag sets may be typed in the reference
1874 to it. From the .abs-file the "tagset" directive takes a third optional
1875 integer type for the tag set referenced. From a .tag-file the "include"
1876 directive takes a third optional type as well. The old "type" directive
1877 in the tag set itself is still recognized but acts as the default type
1880 Backend interface change. Individual Scan terms returned from bend_scan
1881 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1882 in include/backend.h.
1884 Retrieval module enhancements. Multiple tag sets and attribute sets may
1885 be specified in abstract syntax specs. Revised the error/warning for
1886 logging messages reported by the retrieval module when reading the
1889 Object Identifier system (oid_..) changed. The API is backwards
1890 compatible but the oid-routines now allocates new OID's when needed.
1891 Raw OID's may be specified in oid_getvalbyname.
1893 YAZ now uses GNU configure to generate Makefile(s).
1895 * Minor changes in some of the member names of DeleteResultSetRequest and
1896 DeleteResultSetResponse. See include/proto.h.
1898 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1899 and added member 'languages' in TargetInfo (which was missing).
1901 Changed the way attribute sets are handled in the retrieval
1902 module. These are now cached, just like the abstract syntaxes
1905 Changed YAZ so that it links with compiled ASN.1.
1907 Added Explain-schema definitions and mapping routines. The following
1908 Explain categories have been implemented: AttributeDetails,
1909 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1911 Fixed minor bug in Windows version of Server Library.
1913 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1915 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1917 Added EXTERNAL: UNIverse Resource Report (non-standard).
1919 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1920 ENUMERATED and SET OF.
1922 * Added 'const' to some of the char pointer arguments for the
1923 functions, data1_read_node, data1_getelementbytagname,
1924 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1927 Fixed bug in data1_insert_taggeddata - the last_child member of
1928 parent wasn't initialised.
1930 * Changed data1_read_record and data1_read_node so that the supplied
1931 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1932 doesn't refer to any parts of the "SGML"-buffer.
1934 Fixed bug in server library (Windows version of statserv_remove).
1936 * Changed code so that it compiles as C++. The type definition
1937 of Odr_fun which is a member of Odr_arm was changed. The result is,
1938 that an explicit typecast is needed for the fun pointer when
1939 using Odr_arm - as in:
1940 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1942 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1944 Implemented the new structured date and time definition as approved
1945 by the ZIG. Added schemaId element to the specificTag in Espec-1
1946 (also approved at the last ZIG). Thanks to RVDM.
1948 Added some Object identifiers (RVDM).
1950 Changed the Update Extended Service (RVDM).
1952 Added command "refid" to client which specifies referenceId for
1953 the following requests.
1955 Implemented extended service handling for server. See ztest.c
1956 for an example as well as backend.h. New handlers are registerd
1957 in the Init handler.
1959 * Changed interface for sort in server.
1961 Added new members to statserv_options_block. It allows a server
1962 to read options from another source than just the command line. Thanks
1963 to Charles Woodfield.
1965 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1966 renamed to zboolean. Some C++ compilers complained about the name.
1968 Minor changes to gils.abs. Added index 's' (sort) on title
1969 and date/time-last-modified.
1971 --- 1.4pl2 1998/1/30
1973 Fixed bug in server library regarding inetd mode (-i). This bug
1974 was introduced by release 1.4.
1976 --- 1.4pl1 1998/1/29
1978 Added sort facility in client and backend server interface.
1980 Fixed problem with dependencies in Makefile(s).
1982 Fixed bugs for encoders/decoders of extended services and
1985 Implemented sub-tree feature for schemas. Sub-trees are
1986 referenced in *.abs-files. See explain.abs for an example
1987 of the use of this feature.
1989 Modified bib1.att; local attributes for ANY didn't include
1990 ANY itself (only affects use of the retrieval module).
1992 Fixed bug in plain SGML reader in function data1_read_node:
1993 tags with prefix "var" was incorrectly interpreted as variants.
1995 Added feature "sub-schemas" to enable references to - and definitions
1996 of - group of elements.
1998 * Removed member parent from type data1_element (in data1.h).
2000 Implemented function odr_nullval() that returns the value of
2003 * Removed member num_children from data1_node (in data1.h).
2005 Made NT service interface part of the server library. The
2006 function statserv_main uses the NT service when required and
2007 calls the statserv_start / statserv_close routines.
2009 Routine zget_SearchRequest and zget_PresentRequest fills
2010 resultSetName/Id member with "default" instead of "Default".
2012 Fixed memory leak in server. Request queue member wasn't freed.
2014 Fixed nmem_exit so that memory is freed.
2018 Revised the CCL parser utility to be thread safe.
2020 Added function, oid_ent_to_oid, to replace the function
2021 oid_getoidbyent, which is not thread safe.
2023 * Added nmem_init and nmem_exit to initialize and release
2024 NMEM resources. Function nmem_init should be called once in the
2025 initial thread before NMEM/ODR is used. statserv.c and client.c
2026 have been changed accordingly. The change was necessary to make
2027 NMEM thread safe. The NMEM memory pool is shared amongst threads
2028 in a process. Unix-based applications will still work fine without
2031 Added NT Services interface for the the Z39.50 (statserv) Server.
2032 Refer to the ztest.c source on the usage.
2034 Windows 95/NT port using MSVC5.0. Project files are included in the
2037 * Defined new 'global' handle for the retrieval (data1) system. The
2038 new handled, data1_handle, describes the state of the data1 system.
2039 This handle is passed as first argument to virtually all
2040 data1 related routines. The functions data1_create and data1_destroy
2041 creates and destroys a data1 handle respectively.
2043 Added ODR encode stream member to all backend request structures
2044 init, search, scan etc. This stream should be used to allocate all
2045 memory used for the response when thread safe operation is needed.
2047 Changed the comstack utility, cs_addstr, to be thread safe. The
2048 returned hostname string returned by the function is now part the
2051 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2052 function. The cs_straddr takes a COMSTACK handle as argument, so this
2053 function must be used after cs_create and before bind/connect.
2054 This function is thread safe.
2056 Moved test server to 'ztest' directory - generic server code still
2057 in 'server' directory.
2059 Made prefix query (pquery.c) utility thread safe.
2061 Added new function modifier YAZ_EXPORT to 'export' public DLL
2062 functions when using windows (see include/yconfig.h).
2064 Added definitions to the OID database (util/oid.c) (RVDM).
2066 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2068 Added call to ccl_rpn_delete in client program.
2070 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2071 release of RPN structure.
2073 Added support for C++, headers uses extern "C" for public definitions.
2074 With input from RVDM.
2076 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2077 Thanks to Ronald van der Meer (RVDM).
2079 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2081 Added support for private extensions to the OID database
2082 (oid_setprivateoids()). Thanks to RVDM.
2084 Added optional, physical ANY (key replication)
2086 Fixed null-reference problem in GRS-1 output filter.
2088 Proximity operator added to Prefix Query Format (PQF).
2090 In test client command "base" accepts multiple databases.
2092 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2096 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2098 Smallish bug-fixes in the new encoders/decoders (explain).
2100 Bug fixed in DeleteRequest.
2102 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2104 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2106 Added SOIF syntax (using private OID for now) to retrieval module and client.
2108 Added Update extended service.
2110 Added SearchResult-1 additional info structure.
2112 Added optional CCL (ISO8777) interpreter as separate module. Available
2115 --- 1.2 1996/6/10 (1st anniversary release)
2117 Added Summary record syntax. Lightly tested.
2119 Added OPAC record syntax. Untested.
2121 Added ResourceReport service encoders/decoders. Untested.
2123 Fixed bug in z_Unit - wrong tagging on unitSystem.
2125 Fixed bug in the DiagRecs decoder.
2127 Added options for max PDU size and session timeout to frontend-server.
2129 Added documentation of query-language parsers and other supporting utilities.
2131 [frontend-server] Added Attribute set to the bend_scanrequest API.
2133 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2134 surrogate diagnostics were generated.
2136 [retrieval] Allow multiple local values for attribute.
2138 [retrieval] Allow multiple attributes per element in .abs files. index type.
2140 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2142 --- 1.1pl2 1996/4/10
2144 Minor changes, mostly specific to Zebra's requirements (retrieval)
2148 Repaired bug in frontend server when running multiple listening
2149 endpoints in dynamic mode.
2151 z_External() now won't break if a known, ASN.1 value comes encapsulated
2152 in an octet-string. The value will pass through unmodified in an Odr_oct.
2154 Added a bit of code to the demo client to decode & display
2155 ASN.1-structured records represented in the octet-aligned branch of
2156 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2158 Added z_ext_getentbyref() to the ASN module. Doc updated.
2160 * Completed the SCAN definition in the ASN module. This may break SCAN
2161 code based on older YAZ-versions at compile-time. The fix is easy -
2164 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2165 under the SCAN definition. Remember to initialize this, server-people.
2167 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2168 that this does not extend to ODR and ASN.
2170 Comstack allows insertion of established socket (primarily for
2171 inetd-operation of servers). Doc updated.
2173 Front-end server can now start from the inetd in TCP mode. Doc
2176 --- 1.0pl4 1996/1/24
2180 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2181 the rank and record number.
2183 Adjustments to the frontend server.
2185 Fixed diagnostic BER dumper. It ignored the file argument.
2189 Various changes to retrieval module.
2191 Changed the union discriminators of the protocol files from enums to
2192 ints paired with #defines.
2194 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2197 *Changed operator in the RPN structure to 'roperator', again to avoid a
2200 Fixed problems in Explain decoders/encoders.
2202 --- 1.0pl2 1995/12/6
2204 Memory bug in log module fixed.
2206 --- 1.0pl1 1995/12/5
2208 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2210 Bug in Explain DatabaseInfo module fixed.
2212 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2216 The shift to v1.0 signals that we now consider the *core* functionality
2217 of YAZ reasonably stable (the core being more or less equivalent to
2218 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2219 tested (Explain not at all - though that will happen soonish).
2221 Minor changes to code to support Windows port.
2223 Various minor changes after we're getting to use GRS-1 & co. more.
2225 Added Espec-1 format.
2227 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2228 of the protocol and it cannot be selected when encoding (maps into 'string'
2229 when decoding). Needed to talk to some servers.
2231 Demo client can request simple element set names.
2233 Added Diagnostic Format encoders/decoders.
2235 Added simple Close handling to frontend server (no hooks for resource
2236 reporting yet), and demonstration client.
2238 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2240 --- 1.0b3 1995/08/24
2242 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2243 handled incorrectly when records were requested in the searchResponse. This
2244 will only affect you if you use the frontend-server.
2246 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2247 Test-client will ask for and print GRS1. Ztest will return dummy records
2250 Added Explain encoders/decoders to the service-level API. Untested.
2252 Added Extended Services: Item Order encoders and decoders to the Service-
2253 level API. Untested. We could use a recent copy of the pertinent bits
2254 of the ILL protocol to add those bits.
2256 Added diagnostic format 1 encoders/decoders to the service-level API.
2259 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2260 odr_cons.c, which causes a more correct output.
2262 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2263 was always set to 0 when no records were requested in the searchRequest.
2265 * Added better external-handling. This shouldn't harm old code that
2266 *encodes* externals. It can break code that looks for a
2267 'single-ASN1-type' representation, since those types that are known
2268 are now decoded immediately. Look at the SUTRS sample code in
2269 seshigh.c and client.c. Documentation updated.
2271 Handling of structured records in bend_fetchresponse. Length -1 marks
2272 structured record, type is deduced from format field.
2274 --- 1.0b2 1995/06/27
2275 Fairly quick maintenance release to add SUTRS support.
2277 Fixed handling of SUTRS records in the demonstration client.
2279 * Added format field to the bend_fetchrequest and bend_fetchresponce
2280 structures of the backend API (frontend server). When the record is
2281 returned, the value of the format field is mapped to an OID. The
2282 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2283 of the record. The special value VAL_NONE in the bend_request means
2284 that no specific format was requested by the client. Documentation
2285 updated accordingly. Test server (ztest) will return a fixed dummy
2286 SUTRS record if your client requests SUTRS.
2288 Documentation updated accordingly.
2290 You can now set external libraries and RANLIB support in the top-level
2294 First public release.
