1 Tcl scripts uses /usr/bin/tclsh as preferred shell.
3 yaz-ziffy defines _BSD_SOURCE.
5 Changed license of CCL module to 'Revised BSD'. After consultation with
6 remaining members of the original EUROPAGATE consortium, we are re-issuing
7 the CCL module without a separate license. The software was developed by
8 Index Data as part of a research project. The special license was included
9 to help feed usage information back to the project consortium to support
10 project evaluation. At this time, the project consortium has long-since
11 disbanded, and the majority of the original principals have retired. At the
12 same time, we have significantly modified the software during the following
13 years, to the point where very practically no original code remains. To
14 simplify re-use of the software, we have contacted those members of the
15 consortium who could be reached, and agreed to re-issue the module as a
16 proper part of the YAZ package.
20 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
23 yaz-marcdump reads and writes collection wrapped records.
25 Handle OPAC for record conversion module.
27 Fixes for ICU wrapper.
29 Allow ICU libs to be controlled with --with-icu .
33 Added yaz_poll which is a wrapper for select/poll. When poll is available
34 and non-buggy, it is used, by yaz_poll . This allows more than 1024
37 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
38 functionality through an XML based configuration (ICU chain). This system
39 is useful for search facilities such as Pazpar2 and Zebra that needs to
40 perform tokenization of indexed material. The ICU code in a separate
41 library libyaz3_icu.a.
43 Added HTTP tunnel facility for COMSTACK, bug #1752.
44 This is a facility that allows a Web proxy, such as squid, to tunnel
45 Z39.50 traffic. This facility is "transparent" to must applications
46 using YAZ. It's enabled by using pseudo transport connect: followed by
47 the proxy address, followed by command, then follwed by he regular
48 "virtual" addresss. For example,
49 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
51 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
55 Fixed bad memory reference in ZOOM_record - cuased by member not being
56 initialized. This was a problem only in YAZ 3.0.12.
58 Fixed bug in conversion from MARC to XML: Non-XML characters in control
59 fields were not removed.
61 Changed the way C code is generated from codetables.xml. Made a MARC-8
62 conversion trie for each characterSet section rather than codeTable.
63 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
64 of codetables.xml from Larry Dixson, LOC. Bug #1464.
68 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
69 from ZOOM_record_error).
71 ZOOM C function ZOOM_record_get returns record schema for type="schema".
73 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
75 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
77 Better SRW-to-Bib-1 diagnostic mapping.
79 ZOOM C and yaz-client announces SRU version 1.2 by default.
81 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
84 Fixed in yaz_sru_decode to allow other version than 1.1.
88 Added support for SRU scan for ZOOM.
90 Added support for the use of the older versions or Extended Service
91 Update in ZOOM. To faciliate this, an option "updateVersion" may be
92 set to the version , 1=first, 2=second, 3=third. The third version is
93 what ZOOM C has used so far. And that, obviously, is the default.
95 Added support for CCL queries in Z39.50 queries sent to the GFS (and
96 therefore in Zebra and in SimpleServer-based applications). The new
97 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
98 qualifier file used to transform incoming CCL queries into Type-1 RPN,
99 which is passed into the back-end search callback function.
101 Added support for HTTP Basic authentication in clients: the SRU/W
102 codec encodes the username/password elements of the PDU structure
103 appropriately, and these may be set using the "user" and "password"
104 options in ZOOM-C applications (the same options that are used for
105 Z39.50 authentication).
109 Fixed bug #1208: SSL appears to be broken in ZOOM.
111 Fixed bug #1206: Libxml2 include path weirdness.
113 Added oid_name_to_dotstring.
115 Allow elementSetName to be specified for ZOOM C record update.
117 Allow waitAction to be specified for ZOOM C based for Extended Services.
119 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
120 syntax OID. Bug introduced in YAZ 3 series.
122 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
126 Fixed bug #1157: yaz-client does not read .yazclientrc from current
127 directory. yaz-client now reads commands from file given by option -f
128 if specified; then tries to read .yazclientrc in current directory.
129 Failing that, it reads .yazclientrc from user's home directory.
131 Added support for correlationInfo Note and ID for Record Update via
134 Added yaz-client command querycharset which specifies character set for
135 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
136 (termListAndStartPoint).
138 Charset ISO5428:1984 is an alias for ISO5428-1984.
140 Implemented a way to perform scan in a result set using Z39.50. This
141 is achieved by attaching the result set name in the characterInfo
142 (type InternationalString) of OtherInformation in the Scan Request PDU.
143 The result set is identified in the otherinformation by the new OID:
144 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
145 This allows for scan in result set and faceted search . Zebra did some
146 of this in the APT term using attribute type 8 and value being result
147 set. Using the OtherInformation approach for this is cleaner and easier
148 to work with in proxies and the like. This facility can be used in
149 yaz-client using new command setscan which takes a result set as first
150 argument, start position (APT) as second.
152 Changed decoding of SRU XML packed records to deal with servers that
153 have recordData with XML data with multiple root nodes. Also make
154 comparison for recordPacking case insensitive. Again, one server
155 returns "XML" where others return "xml".
157 For SRU responses allow Content-Type application/xml as well as text/xml.
161 Fixed bug in character set conversion of BER strings. Bug introduced
166 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
168 For OID class, use oid_class consistently.
170 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
173 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
174 character set for bibliographic information interchange". By Giannis Kosmas.
176 Added documentation on new OID API.
180 Changes to generic frontend server interface: added new member
181 'query_charset' for bend_initrequest structure. A backend init handler
182 should set this member to its native character set for query terms.
183 When defined, the frontend server logic will announce this character set
184 to a client if the negotiationModel bit is set by the client. All server
185 implementors are encouraged to specify this. If a backend server does not
186 specify this a warning is issued using yaz_log(YLOG_WARN,..).
188 Added CCL utility to remove terms (stop words) from resulting RPN
189 tree. This is handled by functions with prefix ccl_stop_words_ .
191 New ZOOM C option, "rpnCharset", which allows client-side conversion of
192 terms in RPN queries.
194 Clean-up the CCL API. Moved some internal structures from ccl.h to
195 private header cclp.h. Changed ccl_parser_create so that a Bibset must
196 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
197 This is replaced by ccl_parser_find_str which takes a string instead.
199 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
200 libyaz.la is the core of YAZ except the generic frontend server and
201 does not depend on POSIX threads anymore. libyaz_server.la is the
202 generic frontend server facilities and uses POSIX thread functionality
203 if available. The libyaz.la no longer depends on POSIX threads because
204 the number of global structures is limited. NMEM no longer re-uses blocks
205 between threads ; it simply free's memory immediately but allocates in
206 "large" chunks as usual. We don't expect any performance penalties
207 because of this. The yaz_log system is still using a global log_level so
208 caution must be taken when modifying it with yaz_log_init_.. +
209 yaz_log_mask_str. This, however, should not cause any trouble because
210 these functions are called during initialization of application code
211 anyway. `yaz-config --libs server` returns libs for server applications;
212 `yaz-config --libs` returns libs for non-server applications.
214 New OID database - with public definitions in oid_db.h. Removed old OID
215 database including the head oid.h and definitions such as enum oid_value
216 and struct oident. The new OID database uses the same string names as
217 before but the 'protocol' is gone. There are now only two representations
218 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
219 converts from string to OID; functions with prefix yaz_oid_to_string
220 converts the other way.
222 Change to emit_term() in CQL-to-PQF query translation: when a term has
223 the /regexp relation modifier, do not process it for leading and
224 trailing "^" and "*", which have quite different meanings in regular
227 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
228 write handlers no longer carries a 'last' parameter. This will make
229 yaz_iconv flush "less" characters. A flush is performed by call to
230 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
232 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
233 removed, because function yaz_query_to_wrbuf does the same.
235 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
236 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
238 Deprecated MARC utility functions removed.
240 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
243 Branch split: YAZ_2_1_55_branch
245 --- 2.1.54 2007/03/16
247 Fix to ZOOM-C so that transparent reconnection is properly handled on
248 connections that are in asynchronous mode.
250 Fixed compilation on OpenBSD 4.0.
252 Large strings in GRS-1 records are now properly displayed in yaz-client.
254 Added character conversion support for "advancegreek"; based on patch from
257 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
258 sequence is met. Before the error was not set so it would be unknown.
260 Adjust yaz-marcdump MARC reader so that it skips until record separator
263 --- 2.1.52 2007/03/07
265 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
266 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
267 fd_set structure used as a bitmask for the FDs to be selected on.
269 Using ACX_PTHREAD macro to check for POSIX threads.
271 Fixed have-vsnprintf check.
273 --- 2.1.50 2007/02/23
275 Fixes for configure on BSD. Bug #900.
277 Added snprintf/vsnprintf wrappers for systems that don't have
278 limits (heavens forbid).
280 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
281 created before all previous tasks were completed and removed from the
282 task queue, the new task could be removed by a mistake.
284 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
286 Implemented pass-through CQL-to-PQF conversions. Bug #861.
288 Fixed bug #832: Problem with MARC/charset in yaz-client.
290 Fixed bug #668: save command line history for yaz-client.
292 Fixed bug #830: pkg-config support.
294 --- 2.1.48 2007/01/23
296 Extended ZOOM result set options with two options that may be read by
297 a client: resultSetStatus and presentStatus with values as specified for
299 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
301 Fixed bug #827: Using SSL fails on Debian etch.
303 Fixed bug #826: Weird looking chars for set of MARC records.
305 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
306 that is treated as an ItemOrder with itemRequest being an XML document
307 external. The value of "doc" is the content.
309 Extended the GFS search facility. New member of bend_search_rr
310 'estimated_hit_count' signals that hits is known to be an estmate
311 (higher or lower than real hit count). New member 'partial_resultset'
312 signals that the search was partial (hit count is lower or equal than
313 real hit count). For Z39.50, the information is stored in resultSetStatus
314 member of SearchResponse APDU. For SRU, the information is signalled
315 via SRU diagnostic 59: "Result set created with valid partial results
318 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
320 --- 2.1.46 2007/01/13
322 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
324 Added ZOOM_connection_peek_event.
326 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
327 the following new functions:
328 ZOOM_event_nonblock, ZOOM_connection_process,
329 ZOOM_connection_get_{socket,mask,timeout},
330 ZOOM_connection_fire_event_{timeout,socket}.
331 The existing blocking event handler, ZOOM_event, is a wrapper for the
332 + blocking ZOOM_event_sys_{poll,select}.
334 Implemented function ccl_xml_config which parses XML version of CCL
335 configuration (bug #798).
337 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
339 Added timings utility (yaz/timing.h)
341 --- 2.1.44 2007/01/03
343 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
346 Fixed bug #779: Rotation of apdu.log fails.
348 Fixed for character set conversions:
349 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
350 Honor G1 set in MARC-8 decoding.
352 --- 2.1.42 2006/12/17
354 Fixed bug #775: char conversion does not handle Alternative UTF-8
357 Implemented function yaz_marc_read_line which parses MARC line format
358 records. There is a wealth of formats out there. So far, this function
359 reads line records produced by yaz_marc_write_line.
361 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
362 more generic and easier to remember(!) options: -i format and -o format
363 which specifies input format and output format respectively - where
364 format is one of "marc", "marcxml", "line", "marcxchange".
366 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
367 does not print anything except warnings for records.
369 For yaz-marcdump, added support for MARC split into files (-s) with a given
372 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
373 spec, at http://www.loc.gov/standards/sru/record-update/
374 This has changed the binary layout of the following structs:
375 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
376 bend_update_rr . Patch by Ko van der Sloot.
378 Added GFS utility function bend_assoc_is_alive which returns 1 if
379 association is still alive (client is connected); 0 otherwise (client
380 closed connection). This allows busy servers to stop working for
383 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
384 been a separate piece of software. This version of ziffy has been modified
385 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
387 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
389 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
390 Client code may now interrogate options such as "init_opt_sort" to
391 find out whether the server claims to support various options.
393 --- 2.1.40 2006/11/27
395 Added utilities yaz_{set,get}_esn to set/get element set name from
398 Removed the build of libyazthread.la. The libyaz.so is the threaded version
399 of YAZ and has been so since YAZ 2.1.10.
401 Implemented ZOOM_record_error which returns error information for
402 record (surrogate diagnostic).
404 --- 2.1.38 2006/10/31
406 Updates for SRU Update by Ko van der Sloot:
407 1. Changed name from "operation" to "action"
408 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
409 versions in the code, marked as 'backward compatible'.
410 3. Added diagnostics for SRU Update.
412 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
414 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
416 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
418 For GFS, fixed problem with SRU diagnostic 'First record position out of
419 range' being issued for 0 hits.
421 zoomtst10 part of Windows Build.
423 --- 2.1.36 2006/10/13
425 Implemented yaz_filepath_comp which splits a path into file path
426 components (required by Zebra 2.0.3+).
428 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
429 BSD inspired license until now so this should not have any real impact on
430 anybody. See http://www.opensource.org/licenses/bsd-license.php
432 Fixed bug #687: Missing log lines.
434 Fixed bug #678: CQL to PQF translation does not preserve double-quote
437 Fixed bug #689: SRU diagnostics to be added.
439 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
440 whether a connection is idle (no more work do do).
442 --- 2.1.34 2006/10/04
444 Change type of optval from long to int for invocation of setsockopt with
445 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
447 Added support for specifying the max log file size for the Generic
448 Frontend Server. The size is given with option -r.
450 --- 2.1.32 2006/09/21
452 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
454 --- 2.1.30 2006/09/17
456 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
459 Fixed bug in Generic Frontend Server that could cause a server to stop
460 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
462 For the generic frontend server, the maximum record size is used as maximum
463 size of incoming packages (SRU + Z39.50). The value until was previously
464 only used in Z39.50 Init negotiation and, later, in a session controlled
465 sizes of records returned. This is controlled using -k option. It can be
466 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
468 --- 2.1.28 2006/09/04
470 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
473 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
475 New option for yaz-marcdump -lpos=value which allows setting a portion
476 of MARC header to a certain value.
478 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
480 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
481 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
483 --- 2.1.26 2006/08/15
485 Fixed problem with SRU mode type (soap, get, post) for yaz-client
488 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
490 --- 2.1.24 2006/08/08
492 Fixed MARC ISO2709 encoding routines to deal with character set
495 Minor changes to GFS logging. Database included in search request log
498 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
499 cached/multiple records.
501 Shared libraries are built by default on Unix+configure.
503 Changed cql2pqf transformation to use a different evaluation order. The
504 new order is: always, relation, structure, position, truncation, index
505 and relationModifier. Old order was: always, relation, relationModifier,
506 structure, index, position, truncation. Note that the the latter ones
507 override former ones for identical attributes.. The new scheme means that
508 it is possible to override any existing attribute with a relationModifier.
509 And also that it is possible to override everything for the index rule
510 (except the ones listed in relationModifier). No order is perfect but this
511 one, we believe, covers more real cases.. The "always" should have been
512 called "default", since the attributes there can be overridden with all
515 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
516 compilation phase, but also for yaz-config --cflags output. This allows
517 us to have public headers with Libxml2 stuff in them . It should also,
518 eventually, make Libxml2 checks redundant in packages using YAZ, such
521 --- 2.1.22 2006/06/15
523 Changed SRU update structure bend_update_rr so that SRU diagnostics are
524 stored in uri, message and details.. Previously diagnostics were stored
525 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
526 compatibility.. but he's probably the only one affected, so.
528 Added support for CCL, compiled on the client side, in ZOOM-C. This
529 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
530 input; the resulting query objects can be used for for searching with
531 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
533 YAZ' configure searches for OpenSSL by default.
535 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
536 SL_CTX_use_certificate_file. See
537 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
538 for more info. Thanks to Ko van der Sloot.
540 --- 2.1.20 2006/06/02
542 Bug #600: SRU GET, POST support for yaz-client. Introduced
543 command 'sru' which selects method SOAP/GET/POST.
545 Allow missingValueAction to be specified for the sortspec string -
546 function yaz_sort_spec. By default, the missing value action is null.
547 Use ! to specify "abort". Use = followed by stringvalue to specify default
550 Ensured that Present-handler (if defined) is called in GFS before any call to
551 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
552 searchRetrieve requests.
554 Documentation for YAZ is now based on the Docbook XML/XSLT using
555 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
556 is no longer depending on jade/openjade or docbook-to-man scripts.
557 PDF is no longer part of the distribution - but can optionally be
558 made using DSSSL/jadetex or FOP.
560 Added retrieval handling support in Generic Frontend Server to support
561 conversion between MARC/XML as well as XSLTtransforms. See
562 etc/yazgfs.xml for an example.
564 Added Authentication support to Generic Frontend Server in SRU
565 mode. Authentication using HTTP Basic is supported, as is the use
566 of 'x-username' and 'x-password' parameters in the request itself.
568 Added support for a new character set MARC8s identical to MARC8 except
569 that it converts combined characters to single Unicode characters in the
570 Latin-1 range (when possible).
572 --- 2.1.18 2006/04/24
574 ASN.1 compiler 0.4: generates brief Doxygen file header for
575 generated .h/.c files.
577 Utility yaz_iconv now supports conversion to MARC-8.
579 New facilities for the MARC module. The reading - and writing of
580 content are separate methods for the yaz_marc_t handle. The following
581 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
582 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
583 format). Write functions have prefix yaz_marc_write_.. The existing
584 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
585 available. Removed support for OAI-MARC and simplexml (not the
586 simplexml from PHP5).
588 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
589 to be returned for this connection.
591 --- 2.1.16 2006/03/31
593 Allow multiple languages and charsets to be specified with
594 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
595 negcharset iso-8859-1,utf-8
597 Translation of proximity nodes from CQL into PQF now works.
599 Moved to automake 1.8, 1.9.
601 Added function yaz_log_set_handler which allows a log handler to be
602 installed. This handler will be called for all log messages. Output
603 to file is also produced; but that can be disabled by passing NULL
604 fname to yaz_log_init_file.
606 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
608 For SRW (including GFS), accept application/soap+xml as content-type
611 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
612 produces NO stylesheet reference even if a default stylesheet is specified
615 --- 2.1.14 2006/03/14
617 Updated Windows package to include yazd.dll + yazd.lib for the
618 Development component.
620 If the environment variable YAZ_LOG is set, then it is used as a
621 string indicating the default level of logging to use if not
622 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
623 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
624 used as before. So, for example, to omit warnings from YAZ logging,
627 cql_transform() now map structure and other attributes before indexes,
628 so that index-specific structures and other attributes can override
629 defaults. So now a combination of mapping specifications such as:
631 index.dc.date = 1=date-modified 4=5
632 does the right thing.
634 cql_transform() now also respects the "always" mapping specification,
635 which establishes an initial set of attributes to be used for all
636 terms except where overridden by more specific attributes associated
637 with the index, relation or modifier.
639 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
640 which mode to use; one of "post", "get" or "soap" (SRW, default).
642 Fixes for yaz_iconv routines: changed trie-based character set conversions
643 to use only non-negative values for bit fields due to Sun's C compiler not
644 supporting negative values.
646 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
647 sequences where not read correctly. Fix by Rustam Usmanov.
649 Updated win/makefile to use options, settings which makes things
650 compile with VS C 2005.
652 --- 2.1.12 2006/02/01
654 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
656 In ZOOM socket code, use select instead of poll on MacOSX.
658 ZOOM-C now support client-side compilation of CQL into RPN that is
659 sent to the server, enabling CQL to be used against all Z39.50
660 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
661 ZOOM_query object, and submit it using ZOOM_connection_search().
662 The CQL-to-RPN translation uses a configuration file, the name of
663 which must be specified in the Connection's "cqlfile" option.
665 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
666 function, which takes as its start-term parameter a ZOOM_query object
667 (which may have had either CQL or RPN set into it).
670 --- 2.1.10 2005/11/29
672 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
673 GFS to support this as well. Backend handler, bend_srw_update, does the
674 update work. Code contributed by Ko van der Sloot.
676 Allow retrieval of Search Result-1 information in ZOOM by the use of
677 options that are attached to a result set. ZOOM documentation updated
680 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
681 UTF-8 conversion. Patch by Raj Patel.
683 Added option -m to GFS to control formatting of timestamps in log file.
685 Added 'exit' as synonym for 'quit' in yaz-client
687 Added support for specifying SRW resultSetId + resultSetIdleTime in a
688 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
689 for the new members. Patch by Ko van der Sloot.
691 Added support for SRU POST. It is supported for content-type
692 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
694 Do not build the separate Multi-threaded (MT) library libyazthread.la.
695 Instead make the library libyaz.la multi-threaded. Threading as a whole
696 can still be disabled by configure option --disable-threads. Previosly,
697 with older GLIBCs there were problems with MT libs under Apache. This
698 has now been fixed a long time ago.
700 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
703 CQL module modified to be case insensitive for relations/indexes/operations.
705 Fixed bug in CQL transform code: incorrect value relationModifieder
708 Added 'show all' command for yaz-client which retrieves all results
711 Added new yaz-client, xmles, which takes a (private) OID and
712 a document to be sent as an extended service request.
714 Describe new yaz-client commands wait_response and set_auto_wait.
716 Increase TCP/IP listener backlog from 3 (which I am guessing was
717 copied from the SunOS manual entry way back when) so SOMAXCONN, so
718 that the socket will queue as many incoming connections as it's able
719 to handle ongoing connections. In other words, it will never now
720 refuse a connection that it would be able to handle merely because
721 it's not got around to accepting() enough of the pending connections
722 yet. This is the behaviour anyway under Linux, where the listen()
723 argument is ignored; but not under BSD and on systems such as
724 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
725 YAZ-based servers should now be uniform across operating systems in
728 yaz-marcdump uses 64-bit file access on some systems. This is enabled
729 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
730 This allows yaz-marcdump to read large MARC batches (>2 GB).
732 Modified all YAZ source files - except the source which is auto-generated
733 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
736 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
737 corresponding to the existing *_setl() function. These allow option
738 values containing arbitrary valuues.
740 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
741 ZOOM_resultset_sort() in new applications. Its behaviour is identical
742 except that it returns an indicator of whether or not the sort
743 criterion was accepted (0 for OK, -1 for invalid).
747 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
748 MARC output rather than returning "new" buffer.
750 yaz-client warns about unknown init options.
752 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
756 Added support for SRW sort in Generic Frontend Server. Patch
757 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
758 sortKeys - or NULL if none is provided.
760 Fixed bug #307: It was impossible to specify indefinite/no timeout
761 for ZOOM_event. Special timeout value -1 now means indefinite timeout
764 Added support for multiple languages and charsets to be specified in
765 ZOOM. Each charset/language is separated by a blank. If negotiation is
766 in effect in init-response, Option
767 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
768 Code based on patch by Vasiliy Osadchuk.
770 Fixed bug #306: infinite recursion that occurred when calling
771 yaz_log_level_init as the first call (before other log level or
774 Fixed bug in scan handling in front end server: if preferred-Position-In-
775 Response was non-present, a NULL pointer referece was performed.
779 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
780 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
781 now defined for all those error codes. So instead of putting 109 in
782 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
783 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
785 Modified the yaz-marcdump utility to skip garbage bytes between MARC
788 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
790 Program yaz-client now exits and produces an error message if multiple
791 Z39.50 servers are specified on the command line (none or one allowed
794 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
799 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
801 Fixed bug #272: Preserve spacing for CCL terms.
805 Added support for virtual hosts and multiple backend servers for
806 the YAZ frontend server. The configution is XML based and
807 support specificition of CQL to RPN mappings and explain information.
808 See section "Virtual Hosts" in the YAZ manual.
810 Extended OPAC display utility. OPAC display utility renders
811 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
812 to supplement yaz_marc_decode_wrbuf.
814 Fixed a bug in MARC decoder that could caused it to crash for some
815 invalid MARC records. More diagnostics and warnings where added in
816 XML output (warnings, etc are stored in comments).
818 --- 2.0.34 2005/02/08
820 Fixes for UNIX domain sockets. Bug #261.
822 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
824 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
825 Added yaz_marc_subfield_str which defines subfield lead string which is
826 used in YAZ_MARC_LINE format. Default string is blank+$. Added
827 yaz_marc_endline_str which defines end of fields string used in
828 YAZ_MARC_LINE format. Default string is newline.
830 Experimental support for MarcXChange. This format can be produced
831 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
832 http://www.bs.dk/standards/MarcXchange.xsd
834 Added yaz-client commands scansize that sets maximum number of
835 entries to be returned by scan.
837 --- 2.0.32 2005/01/11
839 Added support for SRW scan in yaz-client and Generic Frontend Server.
841 * Added whereInList member to SRW Scan Term.
843 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
845 Fixed NMEM system to return aligned blocks on the smallest boundaries
846 that are suitably aligned for all possible types on the particular
847 architecture YAZ is being built for.
849 --- 2.0.30 2005/01/04
851 Fixed numerious warnings that was issued with newer versions of GCC.
853 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
854 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
857 Make YAZ Generic Frontend Server slightly faster.
859 Enhance (and reduce) logging for Generic Frontend Server.
861 Revert YAZ log system so that it flushes every write operation
862 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
864 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
865 instead of LOG_, due to name clash with syslog(3). LOG_ are still
866 present. New applications should define YAZ_USE_NEW_LOG=1 - this
867 will effectively disable old definitions.
869 --- 2.0.28 2004/11/09
871 Added yaz_log_time_format which specifies log format using
874 Added yaz_log_module_level which returns mask for a module. Value
875 is non-zero mask a if module is enabled; zero if disabled.
877 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
878 in include/yaz/cql.h.
880 Fixed bug #176: Dont throw diagnostics on empty SRU args.
882 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
884 Fixed bug #172: RPM builds does not enable SSL.
886 Doxyfile.in part of dist. Doxyfile generated by configure.
888 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
889 are given and the corresponding component does not exist.
891 Extend CCL documentation in YAZ reference. Describe r=r.
893 --- 2.0.26 2004/10/01
895 Fixed MARC->MARCXML conversion to properly deal with
896 fields, subfields, indicators having non-ASCII characters.
898 Fixed MARC->MARCXML conversion so that ASCII control characters
899 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
902 Added YAZ GFS support for conversion from Z39.50 surrogate
903 diagnostics to SRW surrogate diagnostics.
905 Bug fix: YAZ GFS did not return schema in explainResponse.
907 --- 2.0.25 2004/09/30
909 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
910 now converts recordSchema to elementSetName as well as schema URI.
912 Fixed bug in COMSTACK that prevented HTTP request packages from being
915 --- 2.0.24 2004/09/29
917 Added CCL facility r=r "range" which is similar to r=o "ordered" but
918 does not require white-space before and after the dash in a range, e.g.
919 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
922 Fixed a few AC_TRY_LINK configure tests that did not operate properly
923 due to new GCC removing "redundant" code.
925 Added yaz-client commands scanpos and scanstep that sets preferred
926 position and step-size for scan.
928 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
930 Added CCL utility ccl_qual_buf which parses one or more CCL
931 spec lines in a buffer.
933 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
934 of name and value - ignoring empty lines and comments.
936 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
938 Added odr_get_element_path which returns current element path for an
939 ODR handle. This utility is useful in error handling or user-defined
942 Added ODR_PRINT utility odr_set_stream which is is a more generic
943 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
944 to a write function and pointer to close function. The close function - if
945 non-NULL - will be called during odr_destroy.
947 Fixed bug in CCL parser where truncation char was not removed from
948 right side when truncation=both was in effect.
950 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
953 --- 2.0.23 2004/08/11
955 Fix buffer overrun in CQL parser when dealing with proximity (%).
957 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
958 to UTF-8/UCS conversion is now only based on codetables.xml.
960 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
962 --- 2.0.22 2004/08/06
964 Add support for more "commit changes" in ZOOM (uses Extended Services).
966 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
969 Yet another small fix for configure of SSL.
971 --- 2.0.21 2004/05/14
973 Fix SSL libs for configure when --with-openssl=DIR is given.
975 --- 2.0.20 2004/05/10
977 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
979 SSL comstack now uses yaz.pem certificate file on server side
980 by default. Certificate filename can be configured by calling
981 comstack function cs_set_ssl_certificate_file before cs_bind is used.
983 Fix bug regarding multiple calls to ZOOM_connection_connect.
985 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
987 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
988 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
990 ZOOM now allows inspection of X509 peer certificate for verification.
991 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
993 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
994 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
995 as "modular" but it simplifies things.
997 Added cs_get_peer_certificate to that returns peer X509 PEM.
999 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1000 NULL if SSL is unavailable.
1002 Documentation about MARC decoding tools.
1004 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1006 --- 2.0.19 2004/03/30
1008 Rename CHANGELOG to NEWS to follow GNU style packing.
1010 Fix bug with missing initialization of member in init_diagnostics.
1011 This bug affects threaded version of GFS server.
1013 --- 2.0.18 2004/03/20
1015 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1018 Ensure zlib.dll is packed with Windows install.
1020 --- 2.0.17 2004/03/17
1022 Fix encoding of xsd:string to use text instead of CDATA.
1024 Fix endless loop in CQL parser with unbalanced ".
1026 Use a more compact way to store MARC-8 conversion tables.
1028 --- 2.0.16 2004/03/16 Debian only
1030 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1033 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1038 --- 2.0.15 2004/03/01
1040 Another fix for decoding of XML packed records.
1042 --- 2.0.14 2004/02/25
1044 Fixes for Chunked encoding. White space not ignored after length spec.
1046 Update NS and use default NS for SRW diagnostic elements.
1048 --- 2.0.13 2004/02/23
1050 Implement ZOOM_resultset_cache_reset which resets record cache.
1052 Implement ZOOM_resultset_sort which sorts a result set.
1054 Implement chunked HTTP transfer.
1056 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1058 --- 2.0.12 2004/02/16
1060 Added member 'schema' to bend_explain_rr structure so that backend
1061 can specify explain record identifier. Defaults to Zeerex 2.0.
1063 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1065 --- 2.0.11 2004/02/16
1067 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1070 Added init command for yaz-client which sends "extra" init request.
1072 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1073 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1075 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1077 Make ZOOM error code for "invalid query".
1079 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1081 --- 2.0.10 2004/02/05
1083 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1086 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1088 Added option -p <file> to make Generic Frontend Server to write PID file.
1090 Added option -D to put Generic Frontend Server in background on its own.
1092 Make ZOOM C recognize option "password". If unset, "pass" is used
1093 (for backwards compatibility).
1095 Fixed a bug in Generic Frontend Server that could make it crash if a
1096 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1099 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1100 Must be issued before open, in order to be in effect.
1102 --- 2.0.9-6 2004/01/12 Debian/Windows
1104 Make the SRU server more picky WRT unknown params, etc.
1106 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1108 New YAZ client command, options, that sets Z39.50 options.
1110 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1111 options from a string of tokens (one token for each option bit).
1113 Update SRW diagnostic code messages.
1115 --- 2.0.9-5 2004/01/07 Debian/Windows
1117 Handle user defined stylesheet for SRW/SRU.
1119 --- 2.0.9-4 2004/01/06 Debian/Windows
1121 Fix bug in decoding of Content-Length.
1123 --- 2.0.9-3 2004/01/06 Debian/Windows
1125 Fix a bug with decoding of XML packed records.
1127 --- 2.0.9-2 2004/01/05 Debian only
1129 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1131 Fix bug in SRW/SRU diagnostics decoding.
1133 --- 2.0.9 2004/01/05
1135 Fixed bug in Generic Frontend Server which could drop records exceeding
1136 preferred message size. Reported and fixed by Irina Dijour.
1138 Fixed calculation of package size for structured records in Generic
1139 Frontend Server. Reported and fixed by Irina Dijour.
1141 Fixed namespace for SRW/SRU diagnostics.
1143 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1145 --- 2.0.8 2003/12/22
1147 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1148 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1151 CQL changes to reflect recent changes to the specification:
1152 * Documentation talks about context sets instead of index sets.
1153 * Documentation talks about indexes instead of qualifiers.
1154 * The CQL-to-PQF transformer's configuration file now uses
1155 "index.set.name = <attributes>" instead of the old form
1156 "qualifier.set.name = <attributes>". (Both forms are still
1157 understood but the latter is deprecated.)
1158 * CQL terms with no explicit index specified are now interpreted as
1159 cql.serverChoice instead of srw.serverChoice (which of course
1160 behaves exactly the same.)
1162 --- 2.0.7 2003/12/16
1164 MARC conversion can now generate ISO2709 output in another
1165 character set. yaz-marcdump uses this facility if you invoke it
1168 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1169 functions from there can be used from C++.
1171 --- 2.0.6 2003/12/04
1173 Frontend server now transfers memory from decoded packages to stream
1176 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1177 references to show up.
1179 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1180 the ZOOM Abstract API. The older names for the same options are still
1181 also supported for the benefit of old applications.
1183 ZOOM-C supports "implementationId" and "implementationVersion" options
1184 to go along with "implementationName". These allow the user code to
1185 specify identification strings to be sent to servers.
1186 Add OID for the new ExtLite attribute set.
1188 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1189 as requested/supplid by Ere Maijala <ere@atp.fi>
1191 For generic frontend server, reverse the order of
1192 "toolkit-supplied / application-supplied" strings sent as implementationId,
1193 Name and Version. Also, remove the spaces around the slash. This brings
1194 the GFS in line with the behaviour of ZOOM-C on the client side.
1196 Add function ZOOM_scanset_display_term.
1198 yaz-client shows scan displayTerm if present.
1200 Utility yaz-iconv is now installed by default along with the man page
1203 Extend configure check for OpenSSL to use pkg-config where available (such
1206 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1207 server to specify uid/gid/mask for socket using the format
1208 unix:[user=uid,][group=gid,][umask=mask,]file=path
1209 If file= is omitted the existing format is assumed, e.g.
1211 in which case the mask is 0666 (rw for everybody).
1213 Major restructure of YAZ source. All source in libyaz is in src directory.
1214 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1215 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1217 Added man page for utility yaz-marcdump (used to be called marcdump).
1218 yaz-marcdump is installed by 'make install'.
1220 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1221 of incoming package failed.
1223 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1225 Change prototype of odr_perror: add const to message string.
1227 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1229 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1230 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1231 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1232 DNS lookup. There should not be any compatibility problems with this
1233 assuming that blocking=1 or 0 is used.
1235 Fix bad reference in UNIX comstack in function cs_addrstr.
1237 Fix for compilation on AIX.
1239 The generic front-end server (server/seshigh.c) now supports returning
1240 Init diagnostics to the client in User-information-field, in
1241 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1244 --- 2.0.4 2003/09/04
1246 Allow any CQL relation (not just all,any,exact,scr).
1248 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1249 that features the same UI.
1251 Implemented command update0 in YAZ client which is equivalent to
1252 update but uses old of Ext Update ASN.1.
1254 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1255 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1256 Previously no OID was used for this info.
1258 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1259 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1260 returns 'malformed search term' otherwise.
1262 SortResponse member resultCount now set to NULL in sort handler of
1265 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1268 Add three new utility functions for translating OIDs between various
1269 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1270 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1271 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1272 char *oid_to_dotstring(const int *oid, char *oidbuf);
1273 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1275 Reverted modifications for ES Update definition for z_IU0Update
1276 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1277 is back to YAZ 2.0.2.
1279 String value attributes for CCL parser.
1281 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1282 which their FirstSearch server returns in Init responses, sometimes
1283 carrying useful diagnostic information when Init fails. This has the
1284 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1285 "z39.50/oclcui.asn", where its definition is somewhat different from
1286 what OCLC document on their web-site, as required to interoperate with
1289 Support for anonymous authentication in yaz-client. Use the command
1292 * Fix the OID of the Index Data-local "admin" Extended Service from
1293 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1294 the 1000, which indicates a locally-defined OID, was a mistake.
1296 --- 2.0.3 2003/06/20
1298 Fix CCL directive @case handling so that it affects string match for
1299 both CCL keywords and qualifiers.
1301 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1302 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1303 Decoder has been updated with ASN.1 changes as listed in
1304 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1305 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1306 z_IUUpdate, remains unchanged.
1308 ZOOM_record_get may now return a record in a specific character set.
1309 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1310 "from" is the character set of record as returned by target. "to" is
1311 the character set to be returned. If omitted, "to" is UTF-8.
1313 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1315 New ODR utility, odr_getelement, which returns name of element for
1316 which encoding/decoding failed.
1318 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1319 in cases where a required element was omitted.
1321 Bug fix: some MARC8 sequences were not converted.
1323 New ZOOM option "step" which specifies number of records to be
1324 retrieved in one chunk. Used in conjunction with "start" and "count".
1326 SRW support for yaz-client. Use scheme http: to use it, e.g.
1329 yaz-client no longer does (un)intelligent character set conversions
1330 by default. Can be enabled with charset and marc_charset commands.
1332 xmalloc trace fix for 64-bit systems such as DEC alpha.
1334 Solaris 2.6 compile fix.
1336 New function, cql_strerror() translates SRW error codes, as returned
1337 by cql_transform_error(), into human-readable English strings. Used
1338 in yaz-client diagnostics when appropriate.
1340 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1341 converts it into a type-1 query which is sent to the server. This
1342 makes CQL available for use with all Z-servers, as opposed to the tiny
1343 minority that can handle CQL queries themselves.
1345 --- 2.0.2 2003/04/28
1347 New Debian package layout similar to the Redhat Package layout.
1349 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1350 and search result respectively.
1352 --- 2.0.1 2003/04/25
1354 Redhat package is now several packages: libyaz (runtime libraries),
1355 libyaz-devel (development and documentation, and yaz (utility programs).
1356 Package spec file by Morten Bøgeskov.
1358 New member 'schema' in struct bend_fetch_rr which the name of requested
1359 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1360 handler MAY set this to reflect the schema of the returned record.
1362 New member 'display_term' in struct scan_entry. GFS now sets member entries
1363 and allocates scan entries to be filled by user scan handler. In previous
1364 version, entries member was allocated by the scan handler. That still works,
1365 but the GFS will ignore member display_term - assuming it was NOT set by
1366 the handler. The fact that the GFS now allocates the entries both allows
1367 for new members and makes a scan handler easier to write.
1369 Fix CQL lex buffer overflow.
1371 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1372 SRU default recordPacking is string.
1374 SRU protocol support for frontend server.
1376 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1378 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1380 Added scan for the ZOOM shell (zoomsh).
1384 * String Identifers for Schemas (Amendment 5).
1385 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1386 Old definition for schema
1387 Odr_oid *schema; /* OPT */
1392 Z_InternationalString *uri;
1393 #define Z_Schema_oid 1
1394 #define Z_Schema_uri 2
1397 * resultCount parameter to Sort Response (Amendment 1).
1398 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1400 Support for SRW 1.0 over HTTP. This is an optional feature and
1401 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1404 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1405 on the same port. SRW SearchRetrieveRequests are mapped
1406 to bend_init,bend_search,bend_fetch,bend_close.
1408 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1410 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1411 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1413 ZOOM connections are SRW based if schem http is used for hostname
1414 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1415 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1417 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1418 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1419 distance=n, order=true/false, relation=le, prox unit=word. If
1420 n is omitted, distance 1 is used.
1422 Fixed problem with C compiler include path in wrong order.
1424 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1425 on Solaris. Patch from Ko van der Sloot.
1427 New MARC decode API. All new functions operate on a yaz_marc_t
1428 handle. The most important new functions are: yaz_marc_create,
1429 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1430 decode and destroy respectively. Decoder can produce formats
1431 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1432 include/yaz/marcdisp.h.
1434 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1435 to UTF-8, UCS-32, wchar_t or Latin-1.
1437 * Prototypes for yaz_iconv_-functions moved to separate header
1438 include/yaz/yaz-iconv.h.
1440 Make a few private functions 'static' in unix.c. This prevents
1441 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1443 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1444 are set when Init Response is received.
1446 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1447 but returns diagnostic set as well.
1449 New function yaz_strerror which is a portable wrapper for
1450 strerror/strerror_r/GetLastMessage.
1452 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1453 is returned for MARC. If type is "oai", then OAI MARC is returned.
1455 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1458 --- 1.9.2 2002/11/26
1460 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1462 Fix bad race conditions on SIGTERM and terminate gracefully in
1465 Move retrieval (data1) module to Zebra since nobody seems to be
1468 Add GRS-1 render for ZOOM using same format as yaz-client.
1470 --- 1.9.1 2002/10/05
1472 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1474 Fix broken ESpec handling in data1 module.
1476 SGML reader parses comments and makes them part of the data1 tree.
1478 Added several type casts so that YAZ compiles as C++ code.
1480 ZOOM didn't handle PDU encoding failures properly.
1482 Added more Bib-1 diagnostics (approved extensions).
1484 GNU configure: better check for iconv.
1486 More portable use of accept, getpeername. Check for socklen_t. Use
1487 int/size_t if socklen_t is not defined.
1491 PQF parser rejects bad queries - including those with extra
1492 characters in them. PQF parser used to silently ignore that.
1493 Cleaner API for PQF added, which allows you to get detailed
1494 error information for bad queries (see yaz/pquery.h).
1496 Fixed bug in ZOOM_record_get for type "database".
1498 Implemented mini iconv library supporting conversions between
1499 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1501 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1503 --- 1.8.9 2002/08/20
1505 Fixed ZOOM C record cache so that preferredRecordSyntax and
1506 elementSetName is used to check for already fetched records.
1508 --- 1.8.8 2002/08/02
1510 Added three members in bend_initrequest structure to facilitate
1511 character set negotiation.
1513 Fixed a bug in frontend server that could cause indefinite
1514 loops under rare conditions.
1516 Revised character set utilities (charneg.h) so that encoding
1517 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1519 For PQF, directive @term <type> sets term type for Scan/Search.
1520 Here <type> is general, string, numeric, null. The term type
1521 is inherited - just like @attr.
1523 New call odr_set_charset that sets character set conversion for
1524 international-strings on a ODR stream. Prototype is:
1525 int odr_set_charset(ODR o, const char *to, const char *from);
1526 The InternationalString is still represented as C string in YAZ
1527 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1528 won't). On the protocol level, you can use any encoding.
1530 Support for UNIX sockets in ZOOM.
1532 Solaris recv sometimes returns errno == ENOENT. It is treated as
1533 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1535 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1536 both client and server. Code by Morten Bøgeskov.
1538 --- 1.8.7 2002/05/22
1540 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1541 that they can be used directly from Visual Basic. You must recompile
1542 your windows APP if you're using ZOOM.
1544 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1545 Commands "lang" and "charset" sets language and character set respectively.
1546 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1547 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1549 Attributes from multiple CCL fields may be OR'ed rather than merged
1550 using directive "@field or". Fields are still merged by default -
1551 equivalent to "@field merge".
1553 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1556 Fixed bug in zget for parameter ExtendedServicesResponse.
1560 --- 1.8.6 2002/03/25
1562 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1564 Client displays USR.1:SearchResult-1 (hits per term).
1566 Additional Search Info for search in Generic Frontend Server.
1568 Fixed CCL parsing of "field=s".
1570 WIN32 installer - using the excellent NSIS software from nullsoft.
1572 Fixed CCL parsing of "field = - <number>".
1574 Added function yaz_marc_decode that decodes MARC for line mode
1575 display or XML (similar to that used by JZKit).
1577 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1578 Z39.50. But ISO/ILL was, however.
1580 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1581 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1583 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1584 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1586 --- 1.8.5 2002/02/03
1588 New YAZ client features: Command completion and new commands:
1589 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1590 Code provided by Jacob Poulsen.
1592 New call oid_trav, that visits all registered OIDs via callback.
1594 Function ZOOM_record_get now returns const char pointer rather than
1595 void pointer. It saves a lot of type casts.
1597 For YAZ client, command "auth" now allows you to set authentication
1598 in IdPass style. It is enabled when three tokens are given - order
1599 is user, group and password.
1601 Fix memory leaks in MARC record handling for ZOOM.
1603 New option for YAZ client, -k <kilobytes> that sets
1604 maximum record size. Similar to -k option for generic frontend
1605 server and yaz-ztest.
1607 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1609 Prefix query parser reports "fail" when bad attribute set is given.
1611 Fix in MARC decoder. Proximity logging. Fix for attribute set
1612 in scan handler for server. Patches by Shigeru Ishida.
1614 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1617 Configure option --with-openssl=<dir> now works when a directory is
1618 specified. Patch provided by Morten Bøgeskov.
1620 New option for YAZ client, -u <auth>, that sets authentication.
1622 ZOOM fix: error information was sometimes "missing", since error
1623 was cleared/reset too when it shouldn't.
1625 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1627 --- 1.8.4 2002/01/04
1629 Scan for ZOOM API. New object ZOOM_scanset. New functions
1630 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1631 ZOOM_scanset_destroy.
1633 New ZOOM function, ZOOM_connection_last_event, that returns type
1634 of last event (such as "receive data", "send data", "apdu received",
1637 New ZOOM option, schema, that specifies schema for retrieval.
1639 New CCL feature. Qualifiers can be aliases for one or more
1640 other qualifiers (if more than one is given, OR is used).
1642 ZOOM uses named result sets if target supports it.
1644 Two new YAZ client commands: . (dot, which sources a script of YAZ
1645 client commands), and ! (to execute shell command.). Implemented
1648 Working on Debian packages.
1650 --- 1.8.3 2001/11/19
1652 YAZ client enables named result sets only if target supports it.
1654 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1656 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1657 with key="host" to get same result.
1659 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1660 Function Z3950_resultset_record(s) returns references to records
1661 "owned" by resultset. To become owner use Z3950_record_clone.
1663 Function z_ext_record handles Extended Services. Thanks to
1666 --- 1.8.2 2001/11/12
1668 CCL Parser fix: ignore token comma when dealing with and-lists.
1670 Documentation updates for COMSTACK.
1672 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1673 Changed prototype Z3950_records. For some functions, int parameters
1674 were changed to size_t.
1676 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1679 New MARC decode/display function, marc_display_exl, which properly rejects
1680 non-ISO2709 records. YAZ client uses it.
1682 --- 1.8.1 2001/10/29
1684 Fix bug: local attribute set wasn't set correctly in PQF strings.
1688 * Old Z39.50 codecs no longer supported.
1690 Added ZOOM C binding. See http://zoom.z3950.org/
1692 Renamed states for COMSTACKs to avoid confusion with events.
1694 Implemented cs_look and proper cs_rcvconnect.
1696 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1698 Configure detects POSIX threads on OpenBSD.
1700 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1701 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1703 When error is returned from present handler, non-surrogate diagnostic
1704 is returned in present response (and fetch handler is no longer called).
1706 * Minor adjustments to pquery parser (PQF). Token characters may be
1707 escaped by using backslash (C-style).
1709 PQF parser allows string attribute values to be specified. For @attr,
1710 non-numeric characters after the equal-sign are treated as strings
1711 (e.g. @attr 9=title).
1713 CCL trunction character may be defined (@truncation in file)
1715 * function zget_ExtendedServicesRequest sets waitAction to
1716 waitIfPossible (was wait).
1718 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1721 CCL operator names may be set in field definition files (CCL_bibset).
1722 See ccl/bib1 for an example.
1724 Fixes in ASN.1 compiler for C++ compatibility.
1726 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1727 and "op_or" to avoid conflict with C++.
1729 Fixed problem with GNU readline detection on Redhat 7.0.
1731 Added step-size for Scan backend handler.
1733 Fixed bug that made the frontend server crash when no attribute
1734 set was specified for scan.
1736 Front-end server automatically switches to original working directory
1737 when installed as an NT service. Previously -w had to be specified to
1740 Added extended attributes for retrieval module (data1), so that data1
1741 records carry d1_readXML/SGML attributes. d1_read also supports
1742 null-data rules ( <tag/>)
1744 On UNIX when POSIX threads are available, a separate library libyazthread
1745 is created. Programmers should link with that library and the yaz library
1746 when using threads. The reason for the split was that some applications
1747 on Linux, such as Apache, doesn't work well when using shared objects that
1750 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1751 (or any frontend server) in SSL mode by specifying ssl: followed by
1752 address. Only tested on UNIX.
1754 Added feature for CCL module. Virtual structure s=al or s=ol generates
1755 and-list and or-list respectively instead of phrase search.
1759 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1760 log_mask_str. This was done to avoid name conflicts with other libraries
1761 (such as other PHP extensions).
1763 Added raw OID member for preferred record syntax (request_format_raw)
1764 and returned record syntax (output_format_raw) for backend fetch method.
1766 Config file yaz-config now accepts options so that it returns specific
1767 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1769 Shared library support for UNIX using GNU libtool.
1771 * Modified backend interface. Request/Response struct's replaced by
1772 one read/write C struct. For example bend_fetchrequest and
1773 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1774 Every handler - even search has to be registered in bend_init
1775 handler. This means that the YAZ library no longer refers to
1776 external functions and it makes it possible to make the whole
1777 thing a single DLL/SO.
1779 Added Segment handler for backend server.
1781 Added Zmbol/Zebra administrative functions to YAZ client.
1783 Threaded frontend server on UNIX (when POSIX Threads are available).
1784 Starting the server with option -T enables multi-threading.
1788 Added configure option --enable-comp/disable-comp to control use
1789 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1790 located in sub directory asn.
1792 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1793 in ${exec_prefix}/bin along with the other programs yaz-client and
1796 GNU automake used to maintain makefiles.
1798 Added several OID's.
1800 Changed retrieval module so that we can load records with no abstract
1801 syntax defined. Tagpaths in these records are fully composed of string
1804 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1808 On UNIX, the generated makefile now supports a proper 'make install'.
1809 The prefix can be set via GNU configure to set the install location
1810 (default is /usr/local).
1812 * YAZ programs client and ztest were renamed to yaz-client and
1813 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1814 locations, such as /usr/bin,/usr/local/bin,etc.
1816 * YAZ Header files were moved from include to include/yaz. YAZ Header
1817 files are referred to as include <yaz/log.h> rather than <log.h>.
1818 The YAZ include path (-I ..) is therefore the same as before. Programmers
1819 should update their #include statements or use -Ipath/include/yaz
1820 instead. The main motivation for doing this change is that YAZ header files
1821 can be installed in "standard" locations /usr/include,/usr/local/include
1822 without introducing conflicts, since ALL YAZ header files are stored
1823 in subdirectory yaz (under /usr/include for example).
1825 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1826 rather than project/workspace files. We switched because project files
1827 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1830 Changed name of logging function, logf, to yaz_log, to prevent name
1831 clash with some math-log functions. The YAZ header log.h defines logf
1832 to yaz_log (#define) so there should be no incompatibilities by this
1835 Added bend_start/bend_stop handlers for server. These handler are
1836 called on start/stop of server. For windows they are called whenever
1837 a service is started/stopped.
1839 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1840 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1841 in util/yc.tcl. The auto-generated C code structures are, in a few
1842 cases, incompatible with the old decoders. There are differences in the
1843 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1844 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1845 The preprocessor variable ASN_COMPILED is defined when the compiled
1846 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1847 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1848 wish to use the old encoders/decoders you can specify --disable-yc
1851 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1852 version so that it supports both new - and old version of DB Update
1854 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1855 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1856 change. The name parameter can be set to 0 in which no name is specified
1857 for the construction. The macros odr_implicit and odr_explicit sets name
1858 parameter to zero for the construction involved. New macros
1859 odr_implicit_tag and odr_explicit_tag are similar to the others,
1860 except that a name parameter is added. For programmers' that don't use
1861 ODR they probably only need to change the call to z_APDU and z_External.
1863 Added access control facility by interfacing the TCP wrapper library.
1864 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1865 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1866 name of the daemon and enables the access control as specified in
1867 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1869 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1870 den Dool <H.M.vdnDool@kub.nl>.
1872 Added reference ID parameter to most functions in server API - refer
1873 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1875 Changed name of ccl library to libccl.a (was ccl.a).
1877 Fixed bug in decoder for Explain (Category TargetInfo).
1879 Added support for GNU readline in client. Thanks to Jacob Poulsen
1880 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1882 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1883 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1884 IMPLEMENTATION! This change was made to the development version before
1885 the ZIG decided to retract the amendment. If any users MUST be
1886 compatible with the original Update definition, PLEASE CONTACT US, and
1887 we will include a separate definition corresponding to the old Update
1888 ES. Note that because of the change to the ASN.1 of the
1889 TaskPackageRecordStructure we cannot define a single structure that
1890 will support both versions.
1892 * Added const modifier to buffer parameter for some ODR/BER encoding
1893 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1894 completeWAIS, odr_dumpBER.
1896 Fixed bug in client.c which caused a crash when a scanResponse didn't
1897 contain positionOfTerm.
1899 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1900 * will cause an error in a client if a non-YAZ target sends both a
1901 * list of Scan entries and non-surrogate diagnostics.
1903 Retrieval module enhancements. Tag sets may be typed in the reference
1904 to it. From the .abs-file the "tagset" directive takes a third optional
1905 integer type for the tag set referenced. From a .tag-file the "include"
1906 directive takes a third optional type as well. The old "type" directive
1907 in the tag set itself is still recognized but acts as the default type
1910 Backend interface change. Individual Scan terms returned from bend_scan
1911 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1912 in include/backend.h.
1914 Retrieval module enhancements. Multiple tag sets and attribute sets may
1915 be specified in abstract syntax specs. Revised the error/warning for
1916 logging messages reported by the retrieval module when reading the
1919 Object Identifier system (oid_..) changed. The API is backwards
1920 compatible but the oid-routines now allocates new OID's when needed.
1921 Raw OID's may be specified in oid_getvalbyname.
1923 YAZ now uses GNU configure to generate Makefile(s).
1925 * Minor changes in some of the member names of DeleteResultSetRequest and
1926 DeleteResultSetResponse. See include/proto.h.
1928 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1929 and added member 'languages' in TargetInfo (which was missing).
1931 Changed the way attribute sets are handled in the retrieval
1932 module. These are now cached, just like the abstract syntaxes
1935 Changed YAZ so that it links with compiled ASN.1.
1937 Added Explain-schema definitions and mapping routines. The following
1938 Explain categories have been implemented: AttributeDetails,
1939 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1941 Fixed minor bug in Windows version of Server Library.
1943 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1945 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1947 Added EXTERNAL: UNIverse Resource Report (non-standard).
1949 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1950 ENUMERATED and SET OF.
1952 * Added 'const' to some of the char pointer arguments for the
1953 functions, data1_read_node, data1_getelementbytagname,
1954 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1957 Fixed bug in data1_insert_taggeddata - the last_child member of
1958 parent wasn't initialised.
1960 * Changed data1_read_record and data1_read_node so that the supplied
1961 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1962 doesn't refer to any parts of the "SGML"-buffer.
1964 Fixed bug in server library (Windows version of statserv_remove).
1966 * Changed code so that it compiles as C++. The type definition
1967 of Odr_fun which is a member of Odr_arm was changed. The result is,
1968 that an explicit typecast is needed for the fun pointer when
1969 using Odr_arm - as in:
1970 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1972 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1974 Implemented the new structured date and time definition as approved
1975 by the ZIG. Added schemaId element to the specificTag in Espec-1
1976 (also approved at the last ZIG). Thanks to RVDM.
1978 Added some Object identifiers (RVDM).
1980 Changed the Update Extended Service (RVDM).
1982 Added command "refid" to client which specifies referenceId for
1983 the following requests.
1985 Implemented extended service handling for server. See ztest.c
1986 for an example as well as backend.h. New handlers are registerd
1987 in the Init handler.
1989 * Changed interface for sort in server.
1991 Added new members to statserv_options_block. It allows a server
1992 to read options from another source than just the command line. Thanks
1993 to Charles Woodfield.
1995 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1996 renamed to zboolean. Some C++ compilers complained about the name.
1998 Minor changes to gils.abs. Added index 's' (sort) on title
1999 and date/time-last-modified.
2001 --- 1.4pl2 1998/1/30
2003 Fixed bug in server library regarding inetd mode (-i). This bug
2004 was introduced by release 1.4.
2006 --- 1.4pl1 1998/1/29
2008 Added sort facility in client and backend server interface.
2010 Fixed problem with dependencies in Makefile(s).
2012 Fixed bugs for encoders/decoders of extended services and
2015 Implemented sub-tree feature for schemas. Sub-trees are
2016 referenced in *.abs-files. See explain.abs for an example
2017 of the use of this feature.
2019 Modified bib1.att; local attributes for ANY didn't include
2020 ANY itself (only affects use of the retrieval module).
2022 Fixed bug in plain SGML reader in function data1_read_node:
2023 tags with prefix "var" was incorrectly interpreted as variants.
2025 Added feature "sub-schemas" to enable references to - and definitions
2026 of - group of elements.
2028 * Removed member parent from type data1_element (in data1.h).
2030 Implemented function odr_nullval() that returns the value of
2033 * Removed member num_children from data1_node (in data1.h).
2035 Made NT service interface part of the server library. The
2036 function statserv_main uses the NT service when required and
2037 calls the statserv_start / statserv_close routines.
2039 Routine zget_SearchRequest and zget_PresentRequest fills
2040 resultSetName/Id member with "default" instead of "Default".
2042 Fixed memory leak in server. Request queue member wasn't freed.
2044 Fixed nmem_exit so that memory is freed.
2048 Revised the CCL parser utility to be thread safe.
2050 Added function, oid_ent_to_oid, to replace the function
2051 oid_getoidbyent, which is not thread safe.
2053 * Added nmem_init and nmem_exit to initialize and release
2054 NMEM resources. Function nmem_init should be called once in the
2055 initial thread before NMEM/ODR is used. statserv.c and client.c
2056 have been changed accordingly. The change was necessary to make
2057 NMEM thread safe. The NMEM memory pool is shared amongst threads
2058 in a process. Unix-based applications will still work fine without
2061 Added NT Services interface for the the Z39.50 (statserv) Server.
2062 Refer to the ztest.c source on the usage.
2064 Windows 95/NT port using MSVC5.0. Project files are included in the
2067 * Defined new 'global' handle for the retrieval (data1) system. The
2068 new handled, data1_handle, describes the state of the data1 system.
2069 This handle is passed as first argument to virtually all
2070 data1 related routines. The functions data1_create and data1_destroy
2071 creates and destroys a data1 handle respectively.
2073 Added ODR encode stream member to all backend request structures
2074 init, search, scan etc. This stream should be used to allocate all
2075 memory used for the response when thread safe operation is needed.
2077 Changed the comstack utility, cs_addstr, to be thread safe. The
2078 returned hostname string returned by the function is now part the
2081 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2082 function. The cs_straddr takes a COMSTACK handle as argument, so this
2083 function must be used after cs_create and before bind/connect.
2084 This function is thread safe.
2086 Moved test server to 'ztest' directory - generic server code still
2087 in 'server' directory.
2089 Made prefix query (pquery.c) utility thread safe.
2091 Added new function modifier YAZ_EXPORT to 'export' public DLL
2092 functions when using windows (see include/yconfig.h).
2094 Added definitions to the OID database (util/oid.c) (RVDM).
2096 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2098 Added call to ccl_rpn_delete in client program.
2100 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2101 release of RPN structure.
2103 Added support for C++, headers uses extern "C" for public definitions.
2104 With input from RVDM.
2106 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2107 Thanks to Ronald van der Meer (RVDM).
2109 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2111 Added support for private extensions to the OID database
2112 (oid_setprivateoids()). Thanks to RVDM.
2114 Added optional, physical ANY (key replication)
2116 Fixed null-reference problem in GRS-1 output filter.
2118 Proximity operator added to Prefix Query Format (PQF).
2120 In test client command "base" accepts multiple databases.
2122 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2126 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2128 Smallish bug-fixes in the new encoders/decoders (explain).
2130 Bug fixed in DeleteRequest.
2132 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2134 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2136 Added SOIF syntax (using private OID for now) to retrieval module and client.
2138 Added Update extended service.
2140 Added SearchResult-1 additional info structure.
2142 Added optional CCL (ISO8777) interpreter as separate module. Available
2145 --- 1.2 1996/6/10 (1st anniversary release)
2147 Added Summary record syntax. Lightly tested.
2149 Added OPAC record syntax. Untested.
2151 Added ResourceReport service encoders/decoders. Untested.
2153 Fixed bug in z_Unit - wrong tagging on unitSystem.
2155 Fixed bug in the DiagRecs decoder.
2157 Added options for max PDU size and session timeout to frontend-server.
2159 Added documentation of query-language parsers and other supporting utilities.
2161 [frontend-server] Added Attribute set to the bend_scanrequest API.
2163 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2164 surrogate diagnostics were generated.
2166 [retrieval] Allow multiple local values for attribute.
2168 [retrieval] Allow multiple attributes per element in .abs files. index type.
2170 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2172 --- 1.1pl2 1996/4/10
2174 Minor changes, mostly specific to Zebra's requirements (retrieval)
2178 Repaired bug in frontend server when running multiple listening
2179 endpoints in dynamic mode.
2181 z_External() now won't break if a known, ASN.1 value comes encapsulated
2182 in an octet-string. The value will pass through unmodified in an Odr_oct.
2184 Added a bit of code to the demo client to decode & display
2185 ASN.1-structured records represented in the octet-aligned branch of
2186 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2188 Added z_ext_getentbyref() to the ASN module. Doc updated.
2190 * Completed the SCAN definition in the ASN module. This may break SCAN
2191 code based on older YAZ-versions at compile-time. The fix is easy -
2194 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2195 under the SCAN definition. Remember to initialize this, server-people.
2197 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2198 that this does not extend to ODR and ASN.
2200 Comstack allows insertion of established socket (primarily for
2201 inetd-operation of servers). Doc updated.
2203 Front-end server can now start from the inetd in TCP mode. Doc
2206 --- 1.0pl4 1996/1/24
2210 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2211 the rank and record number.
2213 Adjustments to the frontend server.
2215 Fixed diagnostic BER dumper. It ignored the file argument.
2219 Various changes to retrieval module.
2221 Changed the union discriminators of the protocol files from enums to
2222 ints paired with #defines.
2224 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2227 *Changed operator in the RPN structure to 'roperator', again to avoid a
2230 Fixed problems in Explain decoders/encoders.
2232 --- 1.0pl2 1995/12/6
2234 Memory bug in log module fixed.
2236 --- 1.0pl1 1995/12/5
2238 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2240 Bug in Explain DatabaseInfo module fixed.
2242 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2246 The shift to v1.0 signals that we now consider the *core* functionality
2247 of YAZ reasonably stable (the core being more or less equivalent to
2248 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2249 tested (Explain not at all - though that will happen soonish).
2251 Minor changes to code to support Windows port.
2253 Various minor changes after we're getting to use GRS-1 & co. more.
2255 Added Espec-1 format.
2257 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2258 of the protocol and it cannot be selected when encoding (maps into 'string'
2259 when decoding). Needed to talk to some servers.
2261 Demo client can request simple element set names.
2263 Added Diagnostic Format encoders/decoders.
2265 Added simple Close handling to frontend server (no hooks for resource
2266 reporting yet), and demonstration client.
2268 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2270 --- 1.0b3 1995/08/24
2272 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2273 handled incorrectly when records were requested in the searchResponse. This
2274 will only affect you if you use the frontend-server.
2276 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2277 Test-client will ask for and print GRS1. Ztest will return dummy records
2280 Added Explain encoders/decoders to the service-level API. Untested.
2282 Added Extended Services: Item Order encoders and decoders to the Service-
2283 level API. Untested. We could use a recent copy of the pertinent bits
2284 of the ILL protocol to add those bits.
2286 Added diagnostic format 1 encoders/decoders to the service-level API.
2289 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2290 odr_cons.c, which causes a more correct output.
2292 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2293 was always set to 0 when no records were requested in the searchRequest.
2295 * Added better external-handling. This shouldn't harm old code that
2296 *encodes* externals. It can break code that looks for a
2297 'single-ASN1-type' representation, since those types that are known
2298 are now decoded immediately. Look at the SUTRS sample code in
2299 seshigh.c and client.c. Documentation updated.
2301 Handling of structured records in bend_fetchresponse. Length -1 marks
2302 structured record, type is deduced from format field.
2304 --- 1.0b2 1995/06/27
2305 Fairly quick maintenance release to add SUTRS support.
2307 Fixed handling of SUTRS records in the demonstration client.
2309 * Added format field to the bend_fetchrequest and bend_fetchresponce
2310 structures of the backend API (frontend server). When the record is
2311 returned, the value of the format field is mapped to an OID. The
2312 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2313 of the record. The special value VAL_NONE in the bend_request means
2314 that no specific format was requested by the client. Documentation
2315 updated accordingly. Test server (ztest) will return a fixed dummy
2316 SUTRS record if your client requests SUTRS.
2318 Documentation updated accordingly.
2320 You can now set external libraries and RANLIB support in the top-level
2324 First public release.
