1 yaz-ziffy is no longer part of YAZ. It is distributed separately by
2 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
4 Changed license of CCL module to 'Revised BSD'. After consultation with
5 remaining members of the original EUROPAGATE consortium, we are re-issuing
6 the CCL module without a separate license. The software was developed by
7 Index Data as part of a research project. The special license was included
8 to help feed usage information back to the project consortium to support
9 project evaluation. At this time, the project consortium has long-since
10 disbanded, and the majority of the original principals have retired. At the
11 same time, we have significantly modified the software during the following
12 years, to the point where very practically no original code remains. To
13 simplify re-use of the software, we have contacted those members of the
14 consortium who could be reached, and agreed to re-issue the module as a
15 proper part of the YAZ package.
17 Tcl scripts uses /usr/bin/tclsh as preferred shell.
21 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
24 yaz-marcdump reads and writes collection wrapped records.
26 Handle OPAC for record conversion module.
28 Fixes for ICU wrapper.
30 Allow ICU libs to be controlled with --with-icu .
34 Added yaz_poll which is a wrapper for select/poll. When poll is available
35 and non-buggy, it is used, by yaz_poll . This allows more than 1024
38 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
39 functionality through an XML based configuration (ICU chain). This system
40 is useful for search facilities such as Pazpar2 and Zebra that needs to
41 perform tokenization of indexed material. The ICU code in a separate
42 library libyaz3_icu.a.
44 Added HTTP tunnel facility for COMSTACK, bug #1752.
45 This is a facility that allows a Web proxy, such as squid, to tunnel
46 Z39.50 traffic. This facility is "transparent" to must applications
47 using YAZ. It's enabled by using pseudo transport connect: followed by
48 the proxy address, followed by command, then follwed by he regular
49 "virtual" addresss. For example,
50 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
52 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
56 Fixed bad memory reference in ZOOM_record - cuased by member not being
57 initialized. This was a problem only in YAZ 3.0.12.
59 Fixed bug in conversion from MARC to XML: Non-XML characters in control
60 fields were not removed.
62 Changed the way C code is generated from codetables.xml. Made a MARC-8
63 conversion trie for each characterSet section rather than codeTable.
64 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
65 of codetables.xml from Larry Dixson, LOC. Bug #1464.
69 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
70 from ZOOM_record_error).
72 ZOOM C function ZOOM_record_get returns record schema for type="schema".
74 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
76 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
78 Better SRW-to-Bib-1 diagnostic mapping.
80 ZOOM C and yaz-client announces SRU version 1.2 by default.
82 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
85 Fixed in yaz_sru_decode to allow other version than 1.1.
89 Added support for SRU scan for ZOOM.
91 Added support for the use of the older versions or Extended Service
92 Update in ZOOM. To faciliate this, an option "updateVersion" may be
93 set to the version , 1=first, 2=second, 3=third. The third version is
94 what ZOOM C has used so far. And that, obviously, is the default.
96 Added support for CCL queries in Z39.50 queries sent to the GFS (and
97 therefore in Zebra and in SimpleServer-based applications). The new
98 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
99 qualifier file used to transform incoming CCL queries into Type-1 RPN,
100 which is passed into the back-end search callback function.
102 Added support for HTTP Basic authentication in clients: the SRU/W
103 codec encodes the username/password elements of the PDU structure
104 appropriately, and these may be set using the "user" and "password"
105 options in ZOOM-C applications (the same options that are used for
106 Z39.50 authentication).
110 Fixed bug #1208: SSL appears to be broken in ZOOM.
112 Fixed bug #1206: Libxml2 include path weirdness.
114 Added oid_name_to_dotstring.
116 Allow elementSetName to be specified for ZOOM C record update.
118 Allow waitAction to be specified for ZOOM C based for Extended Services.
120 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
121 syntax OID. Bug introduced in YAZ 3 series.
123 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
127 Fixed bug #1157: yaz-client does not read .yazclientrc from current
128 directory. yaz-client now reads commands from file given by option -f
129 if specified; then tries to read .yazclientrc in current directory.
130 Failing that, it reads .yazclientrc from user's home directory.
132 Added support for correlationInfo Note and ID for Record Update via
135 Added yaz-client command querycharset which specifies character set for
136 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
137 (termListAndStartPoint).
139 Charset ISO5428:1984 is an alias for ISO5428-1984.
141 Implemented a way to perform scan in a result set using Z39.50. This
142 is achieved by attaching the result set name in the characterInfo
143 (type InternationalString) of OtherInformation in the Scan Request PDU.
144 The result set is identified in the otherinformation by the new OID:
145 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
146 This allows for scan in result set and faceted search . Zebra did some
147 of this in the APT term using attribute type 8 and value being result
148 set. Using the OtherInformation approach for this is cleaner and easier
149 to work with in proxies and the like. This facility can be used in
150 yaz-client using new command setscan which takes a result set as first
151 argument, start position (APT) as second.
153 Changed decoding of SRU XML packed records to deal with servers that
154 have recordData with XML data with multiple root nodes. Also make
155 comparison for recordPacking case insensitive. Again, one server
156 returns "XML" where others return "xml".
158 For SRU responses allow Content-Type application/xml as well as text/xml.
162 Fixed bug in character set conversion of BER strings. Bug introduced
167 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
169 For OID class, use oid_class consistently.
171 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
174 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
175 character set for bibliographic information interchange". By Giannis Kosmas.
177 Added documentation on new OID API.
181 Changes to generic frontend server interface: added new member
182 'query_charset' for bend_initrequest structure. A backend init handler
183 should set this member to its native character set for query terms.
184 When defined, the frontend server logic will announce this character set
185 to a client if the negotiationModel bit is set by the client. All server
186 implementors are encouraged to specify this. If a backend server does not
187 specify this a warning is issued using yaz_log(YLOG_WARN,..).
189 Added CCL utility to remove terms (stop words) from resulting RPN
190 tree. This is handled by functions with prefix ccl_stop_words_ .
192 New ZOOM C option, "rpnCharset", which allows client-side conversion of
193 terms in RPN queries.
195 Clean-up the CCL API. Moved some internal structures from ccl.h to
196 private header cclp.h. Changed ccl_parser_create so that a Bibset must
197 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
198 This is replaced by ccl_parser_find_str which takes a string instead.
200 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
201 libyaz.la is the core of YAZ except the generic frontend server and
202 does not depend on POSIX threads anymore. libyaz_server.la is the
203 generic frontend server facilities and uses POSIX thread functionality
204 if available. The libyaz.la no longer depends on POSIX threads because
205 the number of global structures is limited. NMEM no longer re-uses blocks
206 between threads ; it simply free's memory immediately but allocates in
207 "large" chunks as usual. We don't expect any performance penalties
208 because of this. The yaz_log system is still using a global log_level so
209 caution must be taken when modifying it with yaz_log_init_.. +
210 yaz_log_mask_str. This, however, should not cause any trouble because
211 these functions are called during initialization of application code
212 anyway. `yaz-config --libs server` returns libs for server applications;
213 `yaz-config --libs` returns libs for non-server applications.
215 New OID database - with public definitions in oid_db.h. Removed old OID
216 database including the head oid.h and definitions such as enum oid_value
217 and struct oident. The new OID database uses the same string names as
218 before but the 'protocol' is gone. There are now only two representations
219 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
220 converts from string to OID; functions with prefix yaz_oid_to_string
221 converts the other way.
223 Change to emit_term() in CQL-to-PQF query translation: when a term has
224 the /regexp relation modifier, do not process it for leading and
225 trailing "^" and "*", which have quite different meanings in regular
228 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
229 write handlers no longer carries a 'last' parameter. This will make
230 yaz_iconv flush "less" characters. A flush is performed by call to
231 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
233 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
234 removed, because function yaz_query_to_wrbuf does the same.
236 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
237 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
239 Deprecated MARC utility functions removed.
241 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
244 Branch split: YAZ_2_1_55_branch
246 --- 2.1.54 2007/03/16
248 Fix to ZOOM-C so that transparent reconnection is properly handled on
249 connections that are in asynchronous mode.
251 Fixed compilation on OpenBSD 4.0.
253 Large strings in GRS-1 records are now properly displayed in yaz-client.
255 Added character conversion support for "advancegreek"; based on patch from
258 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
259 sequence is met. Before the error was not set so it would be unknown.
261 Adjust yaz-marcdump MARC reader so that it skips until record separator
264 --- 2.1.52 2007/03/07
266 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
267 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
268 fd_set structure used as a bitmask for the FDs to be selected on.
270 Using ACX_PTHREAD macro to check for POSIX threads.
272 Fixed have-vsnprintf check.
274 --- 2.1.50 2007/02/23
276 Fixes for configure on BSD. Bug #900.
278 Added snprintf/vsnprintf wrappers for systems that don't have
279 limits (heavens forbid).
281 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
282 created before all previous tasks were completed and removed from the
283 task queue, the new task could be removed by a mistake.
285 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
287 Implemented pass-through CQL-to-PQF conversions. Bug #861.
289 Fixed bug #832: Problem with MARC/charset in yaz-client.
291 Fixed bug #668: save command line history for yaz-client.
293 Fixed bug #830: pkg-config support.
295 --- 2.1.48 2007/01/23
297 Extended ZOOM result set options with two options that may be read by
298 a client: resultSetStatus and presentStatus with values as specified for
300 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
302 Fixed bug #827: Using SSL fails on Debian etch.
304 Fixed bug #826: Weird looking chars for set of MARC records.
306 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
307 that is treated as an ItemOrder with itemRequest being an XML document
308 external. The value of "doc" is the content.
310 Extended the GFS search facility. New member of bend_search_rr
311 'estimated_hit_count' signals that hits is known to be an estmate
312 (higher or lower than real hit count). New member 'partial_resultset'
313 signals that the search was partial (hit count is lower or equal than
314 real hit count). For Z39.50, the information is stored in resultSetStatus
315 member of SearchResponse APDU. For SRU, the information is signalled
316 via SRU diagnostic 59: "Result set created with valid partial results
319 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
321 --- 2.1.46 2007/01/13
323 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
325 Added ZOOM_connection_peek_event.
327 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
328 the following new functions:
329 ZOOM_event_nonblock, ZOOM_connection_process,
330 ZOOM_connection_get_{socket,mask,timeout},
331 ZOOM_connection_fire_event_{timeout,socket}.
332 The existing blocking event handler, ZOOM_event, is a wrapper for the
333 + blocking ZOOM_event_sys_{poll,select}.
335 Implemented function ccl_xml_config which parses XML version of CCL
336 configuration (bug #798).
338 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
340 Added timings utility (yaz/timing.h)
342 --- 2.1.44 2007/01/03
344 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
347 Fixed bug #779: Rotation of apdu.log fails.
349 Fixed for character set conversions:
350 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
351 Honor G1 set in MARC-8 decoding.
353 --- 2.1.42 2006/12/17
355 Fixed bug #775: char conversion does not handle Alternative UTF-8
358 Implemented function yaz_marc_read_line which parses MARC line format
359 records. There is a wealth of formats out there. So far, this function
360 reads line records produced by yaz_marc_write_line.
362 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
363 more generic and easier to remember(!) options: -i format and -o format
364 which specifies input format and output format respectively - where
365 format is one of "marc", "marcxml", "line", "marcxchange".
367 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
368 does not print anything except warnings for records.
370 For yaz-marcdump, added support for MARC split into files (-s) with a given
373 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
374 spec, at http://www.loc.gov/standards/sru/record-update/
375 This has changed the binary layout of the following structs:
376 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
377 bend_update_rr . Patch by Ko van der Sloot.
379 Added GFS utility function bend_assoc_is_alive which returns 1 if
380 association is still alive (client is connected); 0 otherwise (client
381 closed connection). This allows busy servers to stop working for
384 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
385 been a separate piece of software. This version of ziffy has been modified
386 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
388 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
390 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
391 Client code may now interrogate options such as "init_opt_sort" to
392 find out whether the server claims to support various options.
394 --- 2.1.40 2006/11/27
396 Added utilities yaz_{set,get}_esn to set/get element set name from
399 Removed the build of libyazthread.la. The libyaz.so is the threaded version
400 of YAZ and has been so since YAZ 2.1.10.
402 Implemented ZOOM_record_error which returns error information for
403 record (surrogate diagnostic).
405 --- 2.1.38 2006/10/31
407 Updates for SRU Update by Ko van der Sloot:
408 1. Changed name from "operation" to "action"
409 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
410 versions in the code, marked as 'backward compatible'.
411 3. Added diagnostics for SRU Update.
413 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
415 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
417 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
419 For GFS, fixed problem with SRU diagnostic 'First record position out of
420 range' being issued for 0 hits.
422 zoomtst10 part of Windows Build.
424 --- 2.1.36 2006/10/13
426 Implemented yaz_filepath_comp which splits a path into file path
427 components (required by Zebra 2.0.3+).
429 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
430 BSD inspired license until now so this should not have any real impact on
431 anybody. See http://www.opensource.org/licenses/bsd-license.php
433 Fixed bug #687: Missing log lines.
435 Fixed bug #678: CQL to PQF translation does not preserve double-quote
438 Fixed bug #689: SRU diagnostics to be added.
440 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
441 whether a connection is idle (no more work do do).
443 --- 2.1.34 2006/10/04
445 Change type of optval from long to int for invocation of setsockopt with
446 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
448 Added support for specifying the max log file size for the Generic
449 Frontend Server. The size is given with option -r.
451 --- 2.1.32 2006/09/21
453 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
455 --- 2.1.30 2006/09/17
457 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
460 Fixed bug in Generic Frontend Server that could cause a server to stop
461 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
463 For the generic frontend server, the maximum record size is used as maximum
464 size of incoming packages (SRU + Z39.50). The value until was previously
465 only used in Z39.50 Init negotiation and, later, in a session controlled
466 sizes of records returned. This is controlled using -k option. It can be
467 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
469 --- 2.1.28 2006/09/04
471 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
474 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
476 New option for yaz-marcdump -lpos=value which allows setting a portion
477 of MARC header to a certain value.
479 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
481 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
482 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
484 --- 2.1.26 2006/08/15
486 Fixed problem with SRU mode type (soap, get, post) for yaz-client
489 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
491 --- 2.1.24 2006/08/08
493 Fixed MARC ISO2709 encoding routines to deal with character set
496 Minor changes to GFS logging. Database included in search request log
499 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
500 cached/multiple records.
502 Shared libraries are built by default on Unix+configure.
504 Changed cql2pqf transformation to use a different evaluation order. The
505 new order is: always, relation, structure, position, truncation, index
506 and relationModifier. Old order was: always, relation, relationModifier,
507 structure, index, position, truncation. Note that the the latter ones
508 override former ones for identical attributes.. The new scheme means that
509 it is possible to override any existing attribute with a relationModifier.
510 And also that it is possible to override everything for the index rule
511 (except the ones listed in relationModifier). No order is perfect but this
512 one, we believe, covers more real cases.. The "always" should have been
513 called "default", since the attributes there can be overridden with all
516 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
517 compilation phase, but also for yaz-config --cflags output. This allows
518 us to have public headers with Libxml2 stuff in them . It should also,
519 eventually, make Libxml2 checks redundant in packages using YAZ, such
522 --- 2.1.22 2006/06/15
524 Changed SRU update structure bend_update_rr so that SRU diagnostics are
525 stored in uri, message and details.. Previously diagnostics were stored
526 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
527 compatibility.. but he's probably the only one affected, so.
529 Added support for CCL, compiled on the client side, in ZOOM-C. This
530 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
531 input; the resulting query objects can be used for for searching with
532 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
534 YAZ' configure searches for OpenSSL by default.
536 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
537 SL_CTX_use_certificate_file. See
538 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
539 for more info. Thanks to Ko van der Sloot.
541 --- 2.1.20 2006/06/02
543 Bug #600: SRU GET, POST support for yaz-client. Introduced
544 command 'sru' which selects method SOAP/GET/POST.
546 Allow missingValueAction to be specified for the sortspec string -
547 function yaz_sort_spec. By default, the missing value action is null.
548 Use ! to specify "abort". Use = followed by stringvalue to specify default
551 Ensured that Present-handler (if defined) is called in GFS before any call to
552 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
553 searchRetrieve requests.
555 Documentation for YAZ is now based on the Docbook XML/XSLT using
556 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
557 is no longer depending on jade/openjade or docbook-to-man scripts.
558 PDF is no longer part of the distribution - but can optionally be
559 made using DSSSL/jadetex or FOP.
561 Added retrieval handling support in Generic Frontend Server to support
562 conversion between MARC/XML as well as XSLTtransforms. See
563 etc/yazgfs.xml for an example.
565 Added Authentication support to Generic Frontend Server in SRU
566 mode. Authentication using HTTP Basic is supported, as is the use
567 of 'x-username' and 'x-password' parameters in the request itself.
569 Added support for a new character set MARC8s identical to MARC8 except
570 that it converts combined characters to single Unicode characters in the
571 Latin-1 range (when possible).
573 --- 2.1.18 2006/04/24
575 ASN.1 compiler 0.4: generates brief Doxygen file header for
576 generated .h/.c files.
578 Utility yaz_iconv now supports conversion to MARC-8.
580 New facilities for the MARC module. The reading - and writing of
581 content are separate methods for the yaz_marc_t handle. The following
582 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
583 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
584 format). Write functions have prefix yaz_marc_write_.. The existing
585 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
586 available. Removed support for OAI-MARC and simplexml (not the
587 simplexml from PHP5).
589 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
590 to be returned for this connection.
592 --- 2.1.16 2006/03/31
594 Allow multiple languages and charsets to be specified with
595 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
596 negcharset iso-8859-1,utf-8
598 Translation of proximity nodes from CQL into PQF now works.
600 Moved to automake 1.8, 1.9.
602 Added function yaz_log_set_handler which allows a log handler to be
603 installed. This handler will be called for all log messages. Output
604 to file is also produced; but that can be disabled by passing NULL
605 fname to yaz_log_init_file.
607 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
609 For SRW (including GFS), accept application/soap+xml as content-type
612 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
613 produces NO stylesheet reference even if a default stylesheet is specified
616 --- 2.1.14 2006/03/14
618 Updated Windows package to include yazd.dll + yazd.lib for the
619 Development component.
621 If the environment variable YAZ_LOG is set, then it is used as a
622 string indicating the default level of logging to use if not
623 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
624 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
625 used as before. So, for example, to omit warnings from YAZ logging,
628 cql_transform() now map structure and other attributes before indexes,
629 so that index-specific structures and other attributes can override
630 defaults. So now a combination of mapping specifications such as:
632 index.dc.date = 1=date-modified 4=5
633 does the right thing.
635 cql_transform() now also respects the "always" mapping specification,
636 which establishes an initial set of attributes to be used for all
637 terms except where overridden by more specific attributes associated
638 with the index, relation or modifier.
640 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
641 which mode to use; one of "post", "get" or "soap" (SRW, default).
643 Fixes for yaz_iconv routines: changed trie-based character set conversions
644 to use only non-negative values for bit fields due to Sun's C compiler not
645 supporting negative values.
647 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
648 sequences where not read correctly. Fix by Rustam Usmanov.
650 Updated win/makefile to use options, settings which makes things
651 compile with VS C 2005.
653 --- 2.1.12 2006/02/01
655 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
657 In ZOOM socket code, use select instead of poll on MacOSX.
659 ZOOM-C now support client-side compilation of CQL into RPN that is
660 sent to the server, enabling CQL to be used against all Z39.50
661 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
662 ZOOM_query object, and submit it using ZOOM_connection_search().
663 The CQL-to-RPN translation uses a configuration file, the name of
664 which must be specified in the Connection's "cqlfile" option.
666 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
667 function, which takes as its start-term parameter a ZOOM_query object
668 (which may have had either CQL or RPN set into it).
671 --- 2.1.10 2005/11/29
673 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
674 GFS to support this as well. Backend handler, bend_srw_update, does the
675 update work. Code contributed by Ko van der Sloot.
677 Allow retrieval of Search Result-1 information in ZOOM by the use of
678 options that are attached to a result set. ZOOM documentation updated
681 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
682 UTF-8 conversion. Patch by Raj Patel.
684 Added option -m to GFS to control formatting of timestamps in log file.
686 Added 'exit' as synonym for 'quit' in yaz-client
688 Added support for specifying SRW resultSetId + resultSetIdleTime in a
689 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
690 for the new members. Patch by Ko van der Sloot.
692 Added support for SRU POST. It is supported for content-type
693 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
695 Do not build the separate Multi-threaded (MT) library libyazthread.la.
696 Instead make the library libyaz.la multi-threaded. Threading as a whole
697 can still be disabled by configure option --disable-threads. Previosly,
698 with older GLIBCs there were problems with MT libs under Apache. This
699 has now been fixed a long time ago.
701 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
704 CQL module modified to be case insensitive for relations/indexes/operations.
706 Fixed bug in CQL transform code: incorrect value relationModifieder
709 Added 'show all' command for yaz-client which retrieves all results
712 Added new yaz-client, xmles, which takes a (private) OID and
713 a document to be sent as an extended service request.
715 Describe new yaz-client commands wait_response and set_auto_wait.
717 Increase TCP/IP listener backlog from 3 (which I am guessing was
718 copied from the SunOS manual entry way back when) so SOMAXCONN, so
719 that the socket will queue as many incoming connections as it's able
720 to handle ongoing connections. In other words, it will never now
721 refuse a connection that it would be able to handle merely because
722 it's not got around to accepting() enough of the pending connections
723 yet. This is the behaviour anyway under Linux, where the listen()
724 argument is ignored; but not under BSD and on systems such as
725 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
726 YAZ-based servers should now be uniform across operating systems in
729 yaz-marcdump uses 64-bit file access on some systems. This is enabled
730 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
731 This allows yaz-marcdump to read large MARC batches (>2 GB).
733 Modified all YAZ source files - except the source which is auto-generated
734 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
737 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
738 corresponding to the existing *_setl() function. These allow option
739 values containing arbitrary valuues.
741 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
742 ZOOM_resultset_sort() in new applications. Its behaviour is identical
743 except that it returns an indicator of whether or not the sort
744 criterion was accepted (0 for OK, -1 for invalid).
748 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
749 MARC output rather than returning "new" buffer.
751 yaz-client warns about unknown init options.
753 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
757 Added support for SRW sort in Generic Frontend Server. Patch
758 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
759 sortKeys - or NULL if none is provided.
761 Fixed bug #307: It was impossible to specify indefinite/no timeout
762 for ZOOM_event. Special timeout value -1 now means indefinite timeout
765 Added support for multiple languages and charsets to be specified in
766 ZOOM. Each charset/language is separated by a blank. If negotiation is
767 in effect in init-response, Option
768 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
769 Code based on patch by Vasiliy Osadchuk.
771 Fixed bug #306: infinite recursion that occurred when calling
772 yaz_log_level_init as the first call (before other log level or
775 Fixed bug in scan handling in front end server: if preferred-Position-In-
776 Response was non-present, a NULL pointer referece was performed.
780 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
781 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
782 now defined for all those error codes. So instead of putting 109 in
783 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
784 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
786 Modified the yaz-marcdump utility to skip garbage bytes between MARC
789 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
791 Program yaz-client now exits and produces an error message if multiple
792 Z39.50 servers are specified on the command line (none or one allowed
795 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
800 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
802 Fixed bug #272: Preserve spacing for CCL terms.
806 Added support for virtual hosts and multiple backend servers for
807 the YAZ frontend server. The configution is XML based and
808 support specificition of CQL to RPN mappings and explain information.
809 See section "Virtual Hosts" in the YAZ manual.
811 Extended OPAC display utility. OPAC display utility renders
812 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
813 to supplement yaz_marc_decode_wrbuf.
815 Fixed a bug in MARC decoder that could caused it to crash for some
816 invalid MARC records. More diagnostics and warnings where added in
817 XML output (warnings, etc are stored in comments).
819 --- 2.0.34 2005/02/08
821 Fixes for UNIX domain sockets. Bug #261.
823 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
825 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
826 Added yaz_marc_subfield_str which defines subfield lead string which is
827 used in YAZ_MARC_LINE format. Default string is blank+$. Added
828 yaz_marc_endline_str which defines end of fields string used in
829 YAZ_MARC_LINE format. Default string is newline.
831 Experimental support for MarcXChange. This format can be produced
832 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
833 http://www.bs.dk/standards/MarcXchange.xsd
835 Added yaz-client commands scansize that sets maximum number of
836 entries to be returned by scan.
838 --- 2.0.32 2005/01/11
840 Added support for SRW scan in yaz-client and Generic Frontend Server.
842 * Added whereInList member to SRW Scan Term.
844 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
846 Fixed NMEM system to return aligned blocks on the smallest boundaries
847 that are suitably aligned for all possible types on the particular
848 architecture YAZ is being built for.
850 --- 2.0.30 2005/01/04
852 Fixed numerious warnings that was issued with newer versions of GCC.
854 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
855 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
858 Make YAZ Generic Frontend Server slightly faster.
860 Enhance (and reduce) logging for Generic Frontend Server.
862 Revert YAZ log system so that it flushes every write operation
863 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
865 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
866 instead of LOG_, due to name clash with syslog(3). LOG_ are still
867 present. New applications should define YAZ_USE_NEW_LOG=1 - this
868 will effectively disable old definitions.
870 --- 2.0.28 2004/11/09
872 Added yaz_log_time_format which specifies log format using
875 Added yaz_log_module_level which returns mask for a module. Value
876 is non-zero mask a if module is enabled; zero if disabled.
878 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
879 in include/yaz/cql.h.
881 Fixed bug #176: Dont throw diagnostics on empty SRU args.
883 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
885 Fixed bug #172: RPM builds does not enable SSL.
887 Doxyfile.in part of dist. Doxyfile generated by configure.
889 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
890 are given and the corresponding component does not exist.
892 Extend CCL documentation in YAZ reference. Describe r=r.
894 --- 2.0.26 2004/10/01
896 Fixed MARC->MARCXML conversion to properly deal with
897 fields, subfields, indicators having non-ASCII characters.
899 Fixed MARC->MARCXML conversion so that ASCII control characters
900 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
903 Added YAZ GFS support for conversion from Z39.50 surrogate
904 diagnostics to SRW surrogate diagnostics.
906 Bug fix: YAZ GFS did not return schema in explainResponse.
908 --- 2.0.25 2004/09/30
910 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
911 now converts recordSchema to elementSetName as well as schema URI.
913 Fixed bug in COMSTACK that prevented HTTP request packages from being
916 --- 2.0.24 2004/09/29
918 Added CCL facility r=r "range" which is similar to r=o "ordered" but
919 does not require white-space before and after the dash in a range, e.g.
920 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
923 Fixed a few AC_TRY_LINK configure tests that did not operate properly
924 due to new GCC removing "redundant" code.
926 Added yaz-client commands scanpos and scanstep that sets preferred
927 position and step-size for scan.
929 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
931 Added CCL utility ccl_qual_buf which parses one or more CCL
932 spec lines in a buffer.
934 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
935 of name and value - ignoring empty lines and comments.
937 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
939 Added odr_get_element_path which returns current element path for an
940 ODR handle. This utility is useful in error handling or user-defined
943 Added ODR_PRINT utility odr_set_stream which is is a more generic
944 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
945 to a write function and pointer to close function. The close function - if
946 non-NULL - will be called during odr_destroy.
948 Fixed bug in CCL parser where truncation char was not removed from
949 right side when truncation=both was in effect.
951 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
954 --- 2.0.23 2004/08/11
956 Fix buffer overrun in CQL parser when dealing with proximity (%).
958 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
959 to UTF-8/UCS conversion is now only based on codetables.xml.
961 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
963 --- 2.0.22 2004/08/06
965 Add support for more "commit changes" in ZOOM (uses Extended Services).
967 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
970 Yet another small fix for configure of SSL.
972 --- 2.0.21 2004/05/14
974 Fix SSL libs for configure when --with-openssl=DIR is given.
976 --- 2.0.20 2004/05/10
978 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
980 SSL comstack now uses yaz.pem certificate file on server side
981 by default. Certificate filename can be configured by calling
982 comstack function cs_set_ssl_certificate_file before cs_bind is used.
984 Fix bug regarding multiple calls to ZOOM_connection_connect.
986 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
988 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
989 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
991 ZOOM now allows inspection of X509 peer certificate for verification.
992 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
994 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
995 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
996 as "modular" but it simplifies things.
998 Added cs_get_peer_certificate to that returns peer X509 PEM.
1000 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1001 NULL if SSL is unavailable.
1003 Documentation about MARC decoding tools.
1005 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1007 --- 2.0.19 2004/03/30
1009 Rename CHANGELOG to NEWS to follow GNU style packing.
1011 Fix bug with missing initialization of member in init_diagnostics.
1012 This bug affects threaded version of GFS server.
1014 --- 2.0.18 2004/03/20
1016 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1019 Ensure zlib.dll is packed with Windows install.
1021 --- 2.0.17 2004/03/17
1023 Fix encoding of xsd:string to use text instead of CDATA.
1025 Fix endless loop in CQL parser with unbalanced ".
1027 Use a more compact way to store MARC-8 conversion tables.
1029 --- 2.0.16 2004/03/16 Debian only
1031 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1034 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1039 --- 2.0.15 2004/03/01
1041 Another fix for decoding of XML packed records.
1043 --- 2.0.14 2004/02/25
1045 Fixes for Chunked encoding. White space not ignored after length spec.
1047 Update NS and use default NS for SRW diagnostic elements.
1049 --- 2.0.13 2004/02/23
1051 Implement ZOOM_resultset_cache_reset which resets record cache.
1053 Implement ZOOM_resultset_sort which sorts a result set.
1055 Implement chunked HTTP transfer.
1057 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1059 --- 2.0.12 2004/02/16
1061 Added member 'schema' to bend_explain_rr structure so that backend
1062 can specify explain record identifier. Defaults to Zeerex 2.0.
1064 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1066 --- 2.0.11 2004/02/16
1068 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1071 Added init command for yaz-client which sends "extra" init request.
1073 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1074 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1076 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1078 Make ZOOM error code for "invalid query".
1080 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1082 --- 2.0.10 2004/02/05
1084 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1087 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1089 Added option -p <file> to make Generic Frontend Server to write PID file.
1091 Added option -D to put Generic Frontend Server in background on its own.
1093 Make ZOOM C recognize option "password". If unset, "pass" is used
1094 (for backwards compatibility).
1096 Fixed a bug in Generic Frontend Server that could make it crash if a
1097 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1100 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1101 Must be issued before open, in order to be in effect.
1103 --- 2.0.9-6 2004/01/12 Debian/Windows
1105 Make the SRU server more picky WRT unknown params, etc.
1107 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1109 New YAZ client command, options, that sets Z39.50 options.
1111 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1112 options from a string of tokens (one token for each option bit).
1114 Update SRW diagnostic code messages.
1116 --- 2.0.9-5 2004/01/07 Debian/Windows
1118 Handle user defined stylesheet for SRW/SRU.
1120 --- 2.0.9-4 2004/01/06 Debian/Windows
1122 Fix bug in decoding of Content-Length.
1124 --- 2.0.9-3 2004/01/06 Debian/Windows
1126 Fix a bug with decoding of XML packed records.
1128 --- 2.0.9-2 2004/01/05 Debian only
1130 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1132 Fix bug in SRW/SRU diagnostics decoding.
1134 --- 2.0.9 2004/01/05
1136 Fixed bug in Generic Frontend Server which could drop records exceeding
1137 preferred message size. Reported and fixed by Irina Dijour.
1139 Fixed calculation of package size for structured records in Generic
1140 Frontend Server. Reported and fixed by Irina Dijour.
1142 Fixed namespace for SRW/SRU diagnostics.
1144 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1146 --- 2.0.8 2003/12/22
1148 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1149 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1152 CQL changes to reflect recent changes to the specification:
1153 * Documentation talks about context sets instead of index sets.
1154 * Documentation talks about indexes instead of qualifiers.
1155 * The CQL-to-PQF transformer's configuration file now uses
1156 "index.set.name = <attributes>" instead of the old form
1157 "qualifier.set.name = <attributes>". (Both forms are still
1158 understood but the latter is deprecated.)
1159 * CQL terms with no explicit index specified are now interpreted as
1160 cql.serverChoice instead of srw.serverChoice (which of course
1161 behaves exactly the same.)
1163 --- 2.0.7 2003/12/16
1165 MARC conversion can now generate ISO2709 output in another
1166 character set. yaz-marcdump uses this facility if you invoke it
1169 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1170 functions from there can be used from C++.
1172 --- 2.0.6 2003/12/04
1174 Frontend server now transfers memory from decoded packages to stream
1177 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1178 references to show up.
1180 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1181 the ZOOM Abstract API. The older names for the same options are still
1182 also supported for the benefit of old applications.
1184 ZOOM-C supports "implementationId" and "implementationVersion" options
1185 to go along with "implementationName". These allow the user code to
1186 specify identification strings to be sent to servers.
1187 Add OID for the new ExtLite attribute set.
1189 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1190 as requested/supplid by Ere Maijala <ere@atp.fi>
1192 For generic frontend server, reverse the order of
1193 "toolkit-supplied / application-supplied" strings sent as implementationId,
1194 Name and Version. Also, remove the spaces around the slash. This brings
1195 the GFS in line with the behaviour of ZOOM-C on the client side.
1197 Add function ZOOM_scanset_display_term.
1199 yaz-client shows scan displayTerm if present.
1201 Utility yaz-iconv is now installed by default along with the man page
1204 Extend configure check for OpenSSL to use pkg-config where available (such
1207 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1208 server to specify uid/gid/mask for socket using the format
1209 unix:[user=uid,][group=gid,][umask=mask,]file=path
1210 If file= is omitted the existing format is assumed, e.g.
1212 in which case the mask is 0666 (rw for everybody).
1214 Major restructure of YAZ source. All source in libyaz is in src directory.
1215 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1216 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1218 Added man page for utility yaz-marcdump (used to be called marcdump).
1219 yaz-marcdump is installed by 'make install'.
1221 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1222 of incoming package failed.
1224 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1226 Change prototype of odr_perror: add const to message string.
1228 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1230 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1231 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1232 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1233 DNS lookup. There should not be any compatibility problems with this
1234 assuming that blocking=1 or 0 is used.
1236 Fix bad reference in UNIX comstack in function cs_addrstr.
1238 Fix for compilation on AIX.
1240 The generic front-end server (server/seshigh.c) now supports returning
1241 Init diagnostics to the client in User-information-field, in
1242 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1245 --- 2.0.4 2003/09/04
1247 Allow any CQL relation (not just all,any,exact,scr).
1249 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1250 that features the same UI.
1252 Implemented command update0 in YAZ client which is equivalent to
1253 update but uses old of Ext Update ASN.1.
1255 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1256 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1257 Previously no OID was used for this info.
1259 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1260 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1261 returns 'malformed search term' otherwise.
1263 SortResponse member resultCount now set to NULL in sort handler of
1266 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1269 Add three new utility functions for translating OIDs between various
1270 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1271 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1272 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1273 char *oid_to_dotstring(const int *oid, char *oidbuf);
1274 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1276 Reverted modifications for ES Update definition for z_IU0Update
1277 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1278 is back to YAZ 2.0.2.
1280 String value attributes for CCL parser.
1282 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1283 which their FirstSearch server returns in Init responses, sometimes
1284 carrying useful diagnostic information when Init fails. This has the
1285 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1286 "z39.50/oclcui.asn", where its definition is somewhat different from
1287 what OCLC document on their web-site, as required to interoperate with
1290 Support for anonymous authentication in yaz-client. Use the command
1293 * Fix the OID of the Index Data-local "admin" Extended Service from
1294 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1295 the 1000, which indicates a locally-defined OID, was a mistake.
1297 --- 2.0.3 2003/06/20
1299 Fix CCL directive @case handling so that it affects string match for
1300 both CCL keywords and qualifiers.
1302 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1303 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1304 Decoder has been updated with ASN.1 changes as listed in
1305 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1306 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1307 z_IUUpdate, remains unchanged.
1309 ZOOM_record_get may now return a record in a specific character set.
1310 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1311 "from" is the character set of record as returned by target. "to" is
1312 the character set to be returned. If omitted, "to" is UTF-8.
1314 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1316 New ODR utility, odr_getelement, which returns name of element for
1317 which encoding/decoding failed.
1319 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1320 in cases where a required element was omitted.
1322 Bug fix: some MARC8 sequences were not converted.
1324 New ZOOM option "step" which specifies number of records to be
1325 retrieved in one chunk. Used in conjunction with "start" and "count".
1327 SRW support for yaz-client. Use scheme http: to use it, e.g.
1330 yaz-client no longer does (un)intelligent character set conversions
1331 by default. Can be enabled with charset and marc_charset commands.
1333 xmalloc trace fix for 64-bit systems such as DEC alpha.
1335 Solaris 2.6 compile fix.
1337 New function, cql_strerror() translates SRW error codes, as returned
1338 by cql_transform_error(), into human-readable English strings. Used
1339 in yaz-client diagnostics when appropriate.
1341 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1342 converts it into a type-1 query which is sent to the server. This
1343 makes CQL available for use with all Z-servers, as opposed to the tiny
1344 minority that can handle CQL queries themselves.
1346 --- 2.0.2 2003/04/28
1348 New Debian package layout similar to the Redhat Package layout.
1350 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1351 and search result respectively.
1353 --- 2.0.1 2003/04/25
1355 Redhat package is now several packages: libyaz (runtime libraries),
1356 libyaz-devel (development and documentation, and yaz (utility programs).
1357 Package spec file by Morten Bøgeskov.
1359 New member 'schema' in struct bend_fetch_rr which the name of requested
1360 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1361 handler MAY set this to reflect the schema of the returned record.
1363 New member 'display_term' in struct scan_entry. GFS now sets member entries
1364 and allocates scan entries to be filled by user scan handler. In previous
1365 version, entries member was allocated by the scan handler. That still works,
1366 but the GFS will ignore member display_term - assuming it was NOT set by
1367 the handler. The fact that the GFS now allocates the entries both allows
1368 for new members and makes a scan handler easier to write.
1370 Fix CQL lex buffer overflow.
1372 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1373 SRU default recordPacking is string.
1375 SRU protocol support for frontend server.
1377 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1379 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1381 Added scan for the ZOOM shell (zoomsh).
1385 * String Identifers for Schemas (Amendment 5).
1386 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1387 Old definition for schema
1388 Odr_oid *schema; /* OPT */
1393 Z_InternationalString *uri;
1394 #define Z_Schema_oid 1
1395 #define Z_Schema_uri 2
1398 * resultCount parameter to Sort Response (Amendment 1).
1399 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1401 Support for SRW 1.0 over HTTP. This is an optional feature and
1402 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1405 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1406 on the same port. SRW SearchRetrieveRequests are mapped
1407 to bend_init,bend_search,bend_fetch,bend_close.
1409 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1411 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1412 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1414 ZOOM connections are SRW based if schem http is used for hostname
1415 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1416 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1418 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1419 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1420 distance=n, order=true/false, relation=le, prox unit=word. If
1421 n is omitted, distance 1 is used.
1423 Fixed problem with C compiler include path in wrong order.
1425 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1426 on Solaris. Patch from Ko van der Sloot.
1428 New MARC decode API. All new functions operate on a yaz_marc_t
1429 handle. The most important new functions are: yaz_marc_create,
1430 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1431 decode and destroy respectively. Decoder can produce formats
1432 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1433 include/yaz/marcdisp.h.
1435 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1436 to UTF-8, UCS-32, wchar_t or Latin-1.
1438 * Prototypes for yaz_iconv_-functions moved to separate header
1439 include/yaz/yaz-iconv.h.
1441 Make a few private functions 'static' in unix.c. This prevents
1442 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1444 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1445 are set when Init Response is received.
1447 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1448 but returns diagnostic set as well.
1450 New function yaz_strerror which is a portable wrapper for
1451 strerror/strerror_r/GetLastMessage.
1453 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1454 is returned for MARC. If type is "oai", then OAI MARC is returned.
1456 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1459 --- 1.9.2 2002/11/26
1461 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1463 Fix bad race conditions on SIGTERM and terminate gracefully in
1466 Move retrieval (data1) module to Zebra since nobody seems to be
1469 Add GRS-1 render for ZOOM using same format as yaz-client.
1471 --- 1.9.1 2002/10/05
1473 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1475 Fix broken ESpec handling in data1 module.
1477 SGML reader parses comments and makes them part of the data1 tree.
1479 Added several type casts so that YAZ compiles as C++ code.
1481 ZOOM didn't handle PDU encoding failures properly.
1483 Added more Bib-1 diagnostics (approved extensions).
1485 GNU configure: better check for iconv.
1487 More portable use of accept, getpeername. Check for socklen_t. Use
1488 int/size_t if socklen_t is not defined.
1492 PQF parser rejects bad queries - including those with extra
1493 characters in them. PQF parser used to silently ignore that.
1494 Cleaner API for PQF added, which allows you to get detailed
1495 error information for bad queries (see yaz/pquery.h).
1497 Fixed bug in ZOOM_record_get for type "database".
1499 Implemented mini iconv library supporting conversions between
1500 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1502 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1504 --- 1.8.9 2002/08/20
1506 Fixed ZOOM C record cache so that preferredRecordSyntax and
1507 elementSetName is used to check for already fetched records.
1509 --- 1.8.8 2002/08/02
1511 Added three members in bend_initrequest structure to facilitate
1512 character set negotiation.
1514 Fixed a bug in frontend server that could cause indefinite
1515 loops under rare conditions.
1517 Revised character set utilities (charneg.h) so that encoding
1518 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1520 For PQF, directive @term <type> sets term type for Scan/Search.
1521 Here <type> is general, string, numeric, null. The term type
1522 is inherited - just like @attr.
1524 New call odr_set_charset that sets character set conversion for
1525 international-strings on a ODR stream. Prototype is:
1526 int odr_set_charset(ODR o, const char *to, const char *from);
1527 The InternationalString is still represented as C string in YAZ
1528 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1529 won't). On the protocol level, you can use any encoding.
1531 Support for UNIX sockets in ZOOM.
1533 Solaris recv sometimes returns errno == ENOENT. It is treated as
1534 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1536 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1537 both client and server. Code by Morten Bøgeskov.
1539 --- 1.8.7 2002/05/22
1541 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1542 that they can be used directly from Visual Basic. You must recompile
1543 your windows APP if you're using ZOOM.
1545 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1546 Commands "lang" and "charset" sets language and character set respectively.
1547 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1548 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1550 Attributes from multiple CCL fields may be OR'ed rather than merged
1551 using directive "@field or". Fields are still merged by default -
1552 equivalent to "@field merge".
1554 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1557 Fixed bug in zget for parameter ExtendedServicesResponse.
1561 --- 1.8.6 2002/03/25
1563 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1565 Client displays USR.1:SearchResult-1 (hits per term).
1567 Additional Search Info for search in Generic Frontend Server.
1569 Fixed CCL parsing of "field=s".
1571 WIN32 installer - using the excellent NSIS software from nullsoft.
1573 Fixed CCL parsing of "field = - <number>".
1575 Added function yaz_marc_decode that decodes MARC for line mode
1576 display or XML (similar to that used by JZKit).
1578 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1579 Z39.50. But ISO/ILL was, however.
1581 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1582 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1584 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1585 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1587 --- 1.8.5 2002/02/03
1589 New YAZ client features: Command completion and new commands:
1590 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1591 Code provided by Jacob Poulsen.
1593 New call oid_trav, that visits all registered OIDs via callback.
1595 Function ZOOM_record_get now returns const char pointer rather than
1596 void pointer. It saves a lot of type casts.
1598 For YAZ client, command "auth" now allows you to set authentication
1599 in IdPass style. It is enabled when three tokens are given - order
1600 is user, group and password.
1602 Fix memory leaks in MARC record handling for ZOOM.
1604 New option for YAZ client, -k <kilobytes> that sets
1605 maximum record size. Similar to -k option for generic frontend
1606 server and yaz-ztest.
1608 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1610 Prefix query parser reports "fail" when bad attribute set is given.
1612 Fix in MARC decoder. Proximity logging. Fix for attribute set
1613 in scan handler for server. Patches by Shigeru Ishida.
1615 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1618 Configure option --with-openssl=<dir> now works when a directory is
1619 specified. Patch provided by Morten Bøgeskov.
1621 New option for YAZ client, -u <auth>, that sets authentication.
1623 ZOOM fix: error information was sometimes "missing", since error
1624 was cleared/reset too when it shouldn't.
1626 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1628 --- 1.8.4 2002/01/04
1630 Scan for ZOOM API. New object ZOOM_scanset. New functions
1631 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1632 ZOOM_scanset_destroy.
1634 New ZOOM function, ZOOM_connection_last_event, that returns type
1635 of last event (such as "receive data", "send data", "apdu received",
1638 New ZOOM option, schema, that specifies schema for retrieval.
1640 New CCL feature. Qualifiers can be aliases for one or more
1641 other qualifiers (if more than one is given, OR is used).
1643 ZOOM uses named result sets if target supports it.
1645 Two new YAZ client commands: . (dot, which sources a script of YAZ
1646 client commands), and ! (to execute shell command.). Implemented
1649 Working on Debian packages.
1651 --- 1.8.3 2001/11/19
1653 YAZ client enables named result sets only if target supports it.
1655 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1657 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1658 with key="host" to get same result.
1660 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1661 Function Z3950_resultset_record(s) returns references to records
1662 "owned" by resultset. To become owner use Z3950_record_clone.
1664 Function z_ext_record handles Extended Services. Thanks to
1667 --- 1.8.2 2001/11/12
1669 CCL Parser fix: ignore token comma when dealing with and-lists.
1671 Documentation updates for COMSTACK.
1673 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1674 Changed prototype Z3950_records. For some functions, int parameters
1675 were changed to size_t.
1677 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1680 New MARC decode/display function, marc_display_exl, which properly rejects
1681 non-ISO2709 records. YAZ client uses it.
1683 --- 1.8.1 2001/10/29
1685 Fix bug: local attribute set wasn't set correctly in PQF strings.
1689 * Old Z39.50 codecs no longer supported.
1691 Added ZOOM C binding. See http://zoom.z3950.org/
1693 Renamed states for COMSTACKs to avoid confusion with events.
1695 Implemented cs_look and proper cs_rcvconnect.
1697 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1699 Configure detects POSIX threads on OpenBSD.
1701 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1702 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1704 When error is returned from present handler, non-surrogate diagnostic
1705 is returned in present response (and fetch handler is no longer called).
1707 * Minor adjustments to pquery parser (PQF). Token characters may be
1708 escaped by using backslash (C-style).
1710 PQF parser allows string attribute values to be specified. For @attr,
1711 non-numeric characters after the equal-sign are treated as strings
1712 (e.g. @attr 9=title).
1714 CCL trunction character may be defined (@truncation in file)
1716 * function zget_ExtendedServicesRequest sets waitAction to
1717 waitIfPossible (was wait).
1719 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1722 CCL operator names may be set in field definition files (CCL_bibset).
1723 See ccl/bib1 for an example.
1725 Fixes in ASN.1 compiler for C++ compatibility.
1727 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1728 and "op_or" to avoid conflict with C++.
1730 Fixed problem with GNU readline detection on Redhat 7.0.
1732 Added step-size for Scan backend handler.
1734 Fixed bug that made the frontend server crash when no attribute
1735 set was specified for scan.
1737 Front-end server automatically switches to original working directory
1738 when installed as an NT service. Previously -w had to be specified to
1741 Added extended attributes for retrieval module (data1), so that data1
1742 records carry d1_readXML/SGML attributes. d1_read also supports
1743 null-data rules ( <tag/>)
1745 On UNIX when POSIX threads are available, a separate library libyazthread
1746 is created. Programmers should link with that library and the yaz library
1747 when using threads. The reason for the split was that some applications
1748 on Linux, such as Apache, doesn't work well when using shared objects that
1751 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1752 (or any frontend server) in SSL mode by specifying ssl: followed by
1753 address. Only tested on UNIX.
1755 Added feature for CCL module. Virtual structure s=al or s=ol generates
1756 and-list and or-list respectively instead of phrase search.
1760 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1761 log_mask_str. This was done to avoid name conflicts with other libraries
1762 (such as other PHP extensions).
1764 Added raw OID member for preferred record syntax (request_format_raw)
1765 and returned record syntax (output_format_raw) for backend fetch method.
1767 Config file yaz-config now accepts options so that it returns specific
1768 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1770 Shared library support for UNIX using GNU libtool.
1772 * Modified backend interface. Request/Response struct's replaced by
1773 one read/write C struct. For example bend_fetchrequest and
1774 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1775 Every handler - even search has to be registered in bend_init
1776 handler. This means that the YAZ library no longer refers to
1777 external functions and it makes it possible to make the whole
1778 thing a single DLL/SO.
1780 Added Segment handler for backend server.
1782 Added Zmbol/Zebra administrative functions to YAZ client.
1784 Threaded frontend server on UNIX (when POSIX Threads are available).
1785 Starting the server with option -T enables multi-threading.
1789 Added configure option --enable-comp/disable-comp to control use
1790 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1791 located in sub directory asn.
1793 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1794 in ${exec_prefix}/bin along with the other programs yaz-client and
1797 GNU automake used to maintain makefiles.
1799 Added several OID's.
1801 Changed retrieval module so that we can load records with no abstract
1802 syntax defined. Tagpaths in these records are fully composed of string
1805 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1809 On UNIX, the generated makefile now supports a proper 'make install'.
1810 The prefix can be set via GNU configure to set the install location
1811 (default is /usr/local).
1813 * YAZ programs client and ztest were renamed to yaz-client and
1814 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1815 locations, such as /usr/bin,/usr/local/bin,etc.
1817 * YAZ Header files were moved from include to include/yaz. YAZ Header
1818 files are referred to as include <yaz/log.h> rather than <log.h>.
1819 The YAZ include path (-I ..) is therefore the same as before. Programmers
1820 should update their #include statements or use -Ipath/include/yaz
1821 instead. The main motivation for doing this change is that YAZ header files
1822 can be installed in "standard" locations /usr/include,/usr/local/include
1823 without introducing conflicts, since ALL YAZ header files are stored
1824 in subdirectory yaz (under /usr/include for example).
1826 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1827 rather than project/workspace files. We switched because project files
1828 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1831 Changed name of logging function, logf, to yaz_log, to prevent name
1832 clash with some math-log functions. The YAZ header log.h defines logf
1833 to yaz_log (#define) so there should be no incompatibilities by this
1836 Added bend_start/bend_stop handlers for server. These handler are
1837 called on start/stop of server. For windows they are called whenever
1838 a service is started/stopped.
1840 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1841 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1842 in util/yc.tcl. The auto-generated C code structures are, in a few
1843 cases, incompatible with the old decoders. There are differences in the
1844 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1845 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1846 The preprocessor variable ASN_COMPILED is defined when the compiled
1847 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1848 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1849 wish to use the old encoders/decoders you can specify --disable-yc
1852 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1853 version so that it supports both new - and old version of DB Update
1855 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1856 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1857 change. The name parameter can be set to 0 in which no name is specified
1858 for the construction. The macros odr_implicit and odr_explicit sets name
1859 parameter to zero for the construction involved. New macros
1860 odr_implicit_tag and odr_explicit_tag are similar to the others,
1861 except that a name parameter is added. For programmers' that don't use
1862 ODR they probably only need to change the call to z_APDU and z_External.
1864 Added access control facility by interfacing the TCP wrapper library.
1865 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1866 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1867 name of the daemon and enables the access control as specified in
1868 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1870 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1871 den Dool <H.M.vdnDool@kub.nl>.
1873 Added reference ID parameter to most functions in server API - refer
1874 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1876 Changed name of ccl library to libccl.a (was ccl.a).
1878 Fixed bug in decoder for Explain (Category TargetInfo).
1880 Added support for GNU readline in client. Thanks to Jacob Poulsen
1881 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1883 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1884 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1885 IMPLEMENTATION! This change was made to the development version before
1886 the ZIG decided to retract the amendment. If any users MUST be
1887 compatible with the original Update definition, PLEASE CONTACT US, and
1888 we will include a separate definition corresponding to the old Update
1889 ES. Note that because of the change to the ASN.1 of the
1890 TaskPackageRecordStructure we cannot define a single structure that
1891 will support both versions.
1893 * Added const modifier to buffer parameter for some ODR/BER encoding
1894 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1895 completeWAIS, odr_dumpBER.
1897 Fixed bug in client.c which caused a crash when a scanResponse didn't
1898 contain positionOfTerm.
1900 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1901 * will cause an error in a client if a non-YAZ target sends both a
1902 * list of Scan entries and non-surrogate diagnostics.
1904 Retrieval module enhancements. Tag sets may be typed in the reference
1905 to it. From the .abs-file the "tagset" directive takes a third optional
1906 integer type for the tag set referenced. From a .tag-file the "include"
1907 directive takes a third optional type as well. The old "type" directive
1908 in the tag set itself is still recognized but acts as the default type
1911 Backend interface change. Individual Scan terms returned from bend_scan
1912 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1913 in include/backend.h.
1915 Retrieval module enhancements. Multiple tag sets and attribute sets may
1916 be specified in abstract syntax specs. Revised the error/warning for
1917 logging messages reported by the retrieval module when reading the
1920 Object Identifier system (oid_..) changed. The API is backwards
1921 compatible but the oid-routines now allocates new OID's when needed.
1922 Raw OID's may be specified in oid_getvalbyname.
1924 YAZ now uses GNU configure to generate Makefile(s).
1926 * Minor changes in some of the member names of DeleteResultSetRequest and
1927 DeleteResultSetResponse. See include/proto.h.
1929 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1930 and added member 'languages' in TargetInfo (which was missing).
1932 Changed the way attribute sets are handled in the retrieval
1933 module. These are now cached, just like the abstract syntaxes
1936 Changed YAZ so that it links with compiled ASN.1.
1938 Added Explain-schema definitions and mapping routines. The following
1939 Explain categories have been implemented: AttributeDetails,
1940 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1942 Fixed minor bug in Windows version of Server Library.
1944 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1946 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1948 Added EXTERNAL: UNIverse Resource Report (non-standard).
1950 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1951 ENUMERATED and SET OF.
1953 * Added 'const' to some of the char pointer arguments for the
1954 functions, data1_read_node, data1_getelementbytagname,
1955 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1958 Fixed bug in data1_insert_taggeddata - the last_child member of
1959 parent wasn't initialised.
1961 * Changed data1_read_record and data1_read_node so that the supplied
1962 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1963 doesn't refer to any parts of the "SGML"-buffer.
1965 Fixed bug in server library (Windows version of statserv_remove).
1967 * Changed code so that it compiles as C++. The type definition
1968 of Odr_fun which is a member of Odr_arm was changed. The result is,
1969 that an explicit typecast is needed for the fun pointer when
1970 using Odr_arm - as in:
1971 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1973 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1975 Implemented the new structured date and time definition as approved
1976 by the ZIG. Added schemaId element to the specificTag in Espec-1
1977 (also approved at the last ZIG). Thanks to RVDM.
1979 Added some Object identifiers (RVDM).
1981 Changed the Update Extended Service (RVDM).
1983 Added command "refid" to client which specifies referenceId for
1984 the following requests.
1986 Implemented extended service handling for server. See ztest.c
1987 for an example as well as backend.h. New handlers are registerd
1988 in the Init handler.
1990 * Changed interface for sort in server.
1992 Added new members to statserv_options_block. It allows a server
1993 to read options from another source than just the command line. Thanks
1994 to Charles Woodfield.
1996 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1997 renamed to zboolean. Some C++ compilers complained about the name.
1999 Minor changes to gils.abs. Added index 's' (sort) on title
2000 and date/time-last-modified.
2002 --- 1.4pl2 1998/1/30
2004 Fixed bug in server library regarding inetd mode (-i). This bug
2005 was introduced by release 1.4.
2007 --- 1.4pl1 1998/1/29
2009 Added sort facility in client and backend server interface.
2011 Fixed problem with dependencies in Makefile(s).
2013 Fixed bugs for encoders/decoders of extended services and
2016 Implemented sub-tree feature for schemas. Sub-trees are
2017 referenced in *.abs-files. See explain.abs for an example
2018 of the use of this feature.
2020 Modified bib1.att; local attributes for ANY didn't include
2021 ANY itself (only affects use of the retrieval module).
2023 Fixed bug in plain SGML reader in function data1_read_node:
2024 tags with prefix "var" was incorrectly interpreted as variants.
2026 Added feature "sub-schemas" to enable references to - and definitions
2027 of - group of elements.
2029 * Removed member parent from type data1_element (in data1.h).
2031 Implemented function odr_nullval() that returns the value of
2034 * Removed member num_children from data1_node (in data1.h).
2036 Made NT service interface part of the server library. The
2037 function statserv_main uses the NT service when required and
2038 calls the statserv_start / statserv_close routines.
2040 Routine zget_SearchRequest and zget_PresentRequest fills
2041 resultSetName/Id member with "default" instead of "Default".
2043 Fixed memory leak in server. Request queue member wasn't freed.
2045 Fixed nmem_exit so that memory is freed.
2049 Revised the CCL parser utility to be thread safe.
2051 Added function, oid_ent_to_oid, to replace the function
2052 oid_getoidbyent, which is not thread safe.
2054 * Added nmem_init and nmem_exit to initialize and release
2055 NMEM resources. Function nmem_init should be called once in the
2056 initial thread before NMEM/ODR is used. statserv.c and client.c
2057 have been changed accordingly. The change was necessary to make
2058 NMEM thread safe. The NMEM memory pool is shared amongst threads
2059 in a process. Unix-based applications will still work fine without
2062 Added NT Services interface for the the Z39.50 (statserv) Server.
2063 Refer to the ztest.c source on the usage.
2065 Windows 95/NT port using MSVC5.0. Project files are included in the
2068 * Defined new 'global' handle for the retrieval (data1) system. The
2069 new handled, data1_handle, describes the state of the data1 system.
2070 This handle is passed as first argument to virtually all
2071 data1 related routines. The functions data1_create and data1_destroy
2072 creates and destroys a data1 handle respectively.
2074 Added ODR encode stream member to all backend request structures
2075 init, search, scan etc. This stream should be used to allocate all
2076 memory used for the response when thread safe operation is needed.
2078 Changed the comstack utility, cs_addstr, to be thread safe. The
2079 returned hostname string returned by the function is now part the
2082 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2083 function. The cs_straddr takes a COMSTACK handle as argument, so this
2084 function must be used after cs_create and before bind/connect.
2085 This function is thread safe.
2087 Moved test server to 'ztest' directory - generic server code still
2088 in 'server' directory.
2090 Made prefix query (pquery.c) utility thread safe.
2092 Added new function modifier YAZ_EXPORT to 'export' public DLL
2093 functions when using windows (see include/yconfig.h).
2095 Added definitions to the OID database (util/oid.c) (RVDM).
2097 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2099 Added call to ccl_rpn_delete in client program.
2101 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2102 release of RPN structure.
2104 Added support for C++, headers uses extern "C" for public definitions.
2105 With input from RVDM.
2107 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2108 Thanks to Ronald van der Meer (RVDM).
2110 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2112 Added support for private extensions to the OID database
2113 (oid_setprivateoids()). Thanks to RVDM.
2115 Added optional, physical ANY (key replication)
2117 Fixed null-reference problem in GRS-1 output filter.
2119 Proximity operator added to Prefix Query Format (PQF).
2121 In test client command "base" accepts multiple databases.
2123 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2127 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2129 Smallish bug-fixes in the new encoders/decoders (explain).
2131 Bug fixed in DeleteRequest.
2133 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2135 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2137 Added SOIF syntax (using private OID for now) to retrieval module and client.
2139 Added Update extended service.
2141 Added SearchResult-1 additional info structure.
2143 Added optional CCL (ISO8777) interpreter as separate module. Available
2146 --- 1.2 1996/6/10 (1st anniversary release)
2148 Added Summary record syntax. Lightly tested.
2150 Added OPAC record syntax. Untested.
2152 Added ResourceReport service encoders/decoders. Untested.
2154 Fixed bug in z_Unit - wrong tagging on unitSystem.
2156 Fixed bug in the DiagRecs decoder.
2158 Added options for max PDU size and session timeout to frontend-server.
2160 Added documentation of query-language parsers and other supporting utilities.
2162 [frontend-server] Added Attribute set to the bend_scanrequest API.
2164 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2165 surrogate diagnostics were generated.
2167 [retrieval] Allow multiple local values for attribute.
2169 [retrieval] Allow multiple attributes per element in .abs files. index type.
2171 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2173 --- 1.1pl2 1996/4/10
2175 Minor changes, mostly specific to Zebra's requirements (retrieval)
2179 Repaired bug in frontend server when running multiple listening
2180 endpoints in dynamic mode.
2182 z_External() now won't break if a known, ASN.1 value comes encapsulated
2183 in an octet-string. The value will pass through unmodified in an Odr_oct.
2185 Added a bit of code to the demo client to decode & display
2186 ASN.1-structured records represented in the octet-aligned branch of
2187 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2189 Added z_ext_getentbyref() to the ASN module. Doc updated.
2191 * Completed the SCAN definition in the ASN module. This may break SCAN
2192 code based on older YAZ-versions at compile-time. The fix is easy -
2195 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2196 under the SCAN definition. Remember to initialize this, server-people.
2198 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2199 that this does not extend to ODR and ASN.
2201 Comstack allows insertion of established socket (primarily for
2202 inetd-operation of servers). Doc updated.
2204 Front-end server can now start from the inetd in TCP mode. Doc
2207 --- 1.0pl4 1996/1/24
2211 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2212 the rank and record number.
2214 Adjustments to the frontend server.
2216 Fixed diagnostic BER dumper. It ignored the file argument.
2220 Various changes to retrieval module.
2222 Changed the union discriminators of the protocol files from enums to
2223 ints paired with #defines.
2225 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2228 *Changed operator in the RPN structure to 'roperator', again to avoid a
2231 Fixed problems in Explain decoders/encoders.
2233 --- 1.0pl2 1995/12/6
2235 Memory bug in log module fixed.
2237 --- 1.0pl1 1995/12/5
2239 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2241 Bug in Explain DatabaseInfo module fixed.
2243 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2247 The shift to v1.0 signals that we now consider the *core* functionality
2248 of YAZ reasonably stable (the core being more or less equivalent to
2249 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2250 tested (Explain not at all - though that will happen soonish).
2252 Minor changes to code to support Windows port.
2254 Various minor changes after we're getting to use GRS-1 & co. more.
2256 Added Espec-1 format.
2258 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2259 of the protocol and it cannot be selected when encoding (maps into 'string'
2260 when decoding). Needed to talk to some servers.
2262 Demo client can request simple element set names.
2264 Added Diagnostic Format encoders/decoders.
2266 Added simple Close handling to frontend server (no hooks for resource
2267 reporting yet), and demonstration client.
2269 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2271 --- 1.0b3 1995/08/24
2273 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2274 handled incorrectly when records were requested in the searchResponse. This
2275 will only affect you if you use the frontend-server.
2277 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2278 Test-client will ask for and print GRS1. Ztest will return dummy records
2281 Added Explain encoders/decoders to the service-level API. Untested.
2283 Added Extended Services: Item Order encoders and decoders to the Service-
2284 level API. Untested. We could use a recent copy of the pertinent bits
2285 of the ILL protocol to add those bits.
2287 Added diagnostic format 1 encoders/decoders to the service-level API.
2290 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2291 odr_cons.c, which causes a more correct output.
2293 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2294 was always set to 0 when no records were requested in the searchRequest.
2296 * Added better external-handling. This shouldn't harm old code that
2297 *encodes* externals. It can break code that looks for a
2298 'single-ASN1-type' representation, since those types that are known
2299 are now decoded immediately. Look at the SUTRS sample code in
2300 seshigh.c and client.c. Documentation updated.
2302 Handling of structured records in bend_fetchresponse. Length -1 marks
2303 structured record, type is deduced from format field.
2305 --- 1.0b2 1995/06/27
2306 Fairly quick maintenance release to add SUTRS support.
2308 Fixed handling of SUTRS records in the demonstration client.
2310 * Added format field to the bend_fetchrequest and bend_fetchresponce
2311 structures of the backend API (frontend server). When the record is
2312 returned, the value of the format field is mapped to an OID. The
2313 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2314 of the record. The special value VAL_NONE in the bend_request means
2315 that no specific format was requested by the client. Documentation
2316 updated accordingly. Test server (ztest) will return a fixed dummy
2317 SUTRS record if your client requests SUTRS.
2319 Documentation updated accordingly.
2321 You can now set external libraries and RANLIB support in the top-level
2325 First public release.
