1 Changed license of CCL module to 'Revised BSD'. After consultation with
2 remaining members of the original EUROPAGATE consortium, we are re-issuing
3 the CCL module without a separate license. The software was developed by
4 Index Data as part of a research project. The special license was included
5 to help feed usage information back to the project consortium to support
6 project evaluation. At this time, the project consortium has long-since
7 disbanded, and the majority of the original principals have retired. At the
8 same time, we have significantly modified the software during the following
9 years, to the point where very practically no original code remains. To
10 simplify re-use of the software, we have contacted those members of the
11 consortium who could be reached, and agreed to re-issue the module as a
12 proper part of the YAZ package.
16 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
19 yaz-marcdump reads and writes collection wrapped records.
21 Handle OPAC for record conversion module.
23 Fixes for ICU wrapper.
25 Allow ICU libs to be controlled with --with-icu .
29 Added yaz_poll which is a wrapper for select/poll. When poll is available
30 and non-buggy, it is used, by yaz_poll . This allows more than 1024
33 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
34 functionality through an XML based configuration (ICU chain). This system
35 is useful for search facilities such as Pazpar2 and Zebra that needs to
36 perform tokenization of indexed material. The ICU code in a separate
37 library libyaz3_icu.a.
39 Added HTTP tunnel facility for COMSTACK, bug #1752.
40 This is a facility that allows a Web proxy, such as squid, to tunnel
41 Z39.50 traffic. This facility is "transparent" to must applications
42 using YAZ. It's enabled by using pseudo transport connect: followed by
43 the proxy address, followed by command, then follwed by he regular
44 "virtual" addresss. For example,
45 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
47 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
51 Fixed bad memory reference in ZOOM_record - cuased by member not being
52 initialized. This was a problem only in YAZ 3.0.12.
54 Fixed bug in conversion from MARC to XML: Non-XML characters in control
55 fields were not removed.
57 Changed the way C code is generated from codetables.xml. Made a MARC-8
58 conversion trie for each characterSet section rather than codeTable.
59 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
60 of codetables.xml from Larry Dixson, LOC. Bug #1464.
64 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
65 from ZOOM_record_error).
67 ZOOM C function ZOOM_record_get returns record schema for type="schema".
69 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
71 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
73 Better SRW-to-Bib-1 diagnostic mapping.
75 ZOOM C and yaz-client announces SRU version 1.2 by default.
77 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
80 Fixed in yaz_sru_decode to allow other version than 1.1.
84 Added support for SRU scan for ZOOM.
86 Added support for the use of the older versions or Extended Service
87 Update in ZOOM. To faciliate this, an option "updateVersion" may be
88 set to the version , 1=first, 2=second, 3=third. The third version is
89 what ZOOM C has used so far. And that, obviously, is the default.
91 Added support for CCL queries in Z39.50 queries sent to the GFS (and
92 therefore in Zebra and in SimpleServer-based applications). The new
93 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
94 qualifier file used to transform incoming CCL queries into Type-1 RPN,
95 which is passed into the back-end search callback function.
97 Added support for HTTP Basic authentication in clients: the SRU/W
98 codec encodes the username/password elements of the PDU structure
99 appropriately, and these may be set using the "user" and "password"
100 options in ZOOM-C applications (the same options that are used for
101 Z39.50 authentication).
105 Fixed bug #1208: SSL appears to be broken in ZOOM.
107 Fixed bug #1206: Libxml2 include path weirdness.
109 Added oid_name_to_dotstring.
111 Allow elementSetName to be specified for ZOOM C record update.
113 Allow waitAction to be specified for ZOOM C based for Extended Services.
115 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
116 syntax OID. Bug introduced in YAZ 3 series.
118 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
122 Fixed bug #1157: yaz-client does not read .yazclientrc from current
123 directory. yaz-client now reads commands from file given by option -f
124 if specified; then tries to read .yazclientrc in current directory.
125 Failing that, it reads .yazclientrc from user's home directory.
127 Added support for correlationInfo Note and ID for Record Update via
130 Added yaz-client command querycharset which specifies character set for
131 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
132 (termListAndStartPoint).
134 Charset ISO5428:1984 is an alias for ISO5428-1984.
136 Implemented a way to perform scan in a result set using Z39.50. This
137 is achieved by attaching the result set name in the characterInfo
138 (type InternationalString) of OtherInformation in the Scan Request PDU.
139 The result set is identified in the otherinformation by the new OID:
140 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
141 This allows for scan in result set and faceted search . Zebra did some
142 of this in the APT term using attribute type 8 and value being result
143 set. Using the OtherInformation approach for this is cleaner and easier
144 to work with in proxies and the like. This facility can be used in
145 yaz-client using new command setscan which takes a result set as first
146 argument, start position (APT) as second.
148 Changed decoding of SRU XML packed records to deal with servers that
149 have recordData with XML data with multiple root nodes. Also make
150 comparison for recordPacking case insensitive. Again, one server
151 returns "XML" where others return "xml".
153 For SRU responses allow Content-Type application/xml as well as text/xml.
157 Fixed bug in character set conversion of BER strings. Bug introduced
162 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
164 For OID class, use oid_class consistently.
166 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
169 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
170 character set for bibliographic information interchange". By Giannis Kosmas.
172 Added documentation on new OID API.
176 Changes to generic frontend server interface: added new member
177 'query_charset' for bend_initrequest structure. A backend init handler
178 should set this member to its native character set for query terms.
179 When defined, the frontend server logic will announce this character set
180 to a client if the negotiationModel bit is set by the client. All server
181 implementors are encouraged to specify this. If a backend server does not
182 specify this a warning is issued using yaz_log(YLOG_WARN,..).
184 Added CCL utility to remove terms (stop words) from resulting RPN
185 tree. This is handled by functions with prefix ccl_stop_words_ .
187 New ZOOM C option, "rpnCharset", which allows client-side conversion of
188 terms in RPN queries.
190 Clean-up the CCL API. Moved some internal structures from ccl.h to
191 private header cclp.h. Changed ccl_parser_create so that a Bibset must
192 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
193 This is replaced by ccl_parser_find_str which takes a string instead.
195 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
196 libyaz.la is the core of YAZ except the generic frontend server and
197 does not depend on POSIX threads anymore. libyaz_server.la is the
198 generic frontend server facilities and uses POSIX thread functionality
199 if available. The libyaz.la no longer depends on POSIX threads because
200 the number of global structures is limited. NMEM no longer re-uses blocks
201 between threads ; it simply free's memory immediately but allocates in
202 "large" chunks as usual. We don't expect any performance penalties
203 because of this. The yaz_log system is still using a global log_level so
204 caution must be taken when modifying it with yaz_log_init_.. +
205 yaz_log_mask_str. This, however, should not cause any trouble because
206 these functions are called during initialization of application code
207 anyway. `yaz-config --libs server` returns libs for server applications;
208 `yaz-config --libs` returns libs for non-server applications.
210 New OID database - with public definitions in oid_db.h. Removed old OID
211 database including the head oid.h and definitions such as enum oid_value
212 and struct oident. The new OID database uses the same string names as
213 before but the 'protocol' is gone. There are now only two representations
214 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
215 converts from string to OID; functions with prefix yaz_oid_to_string
216 converts the other way.
218 Change to emit_term() in CQL-to-PQF query translation: when a term has
219 the /regexp relation modifier, do not process it for leading and
220 trailing "^" and "*", which have quite different meanings in regular
223 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
224 write handlers no longer carries a 'last' parameter. This will make
225 yaz_iconv flush "less" characters. A flush is performed by call to
226 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
228 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
229 removed, because function yaz_query_to_wrbuf does the same.
231 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
232 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
234 Deprecated MARC utility functions removed.
236 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
239 Branch split: YAZ_2_1_55_branch
241 --- 2.1.54 2007/03/16
243 Fix to ZOOM-C so that transparent reconnection is properly handled on
244 connections that are in asynchronous mode.
246 Fixed compilation on OpenBSD 4.0.
248 Large strings in GRS-1 records are now properly displayed in yaz-client.
250 Added character conversion support for "advancegreek"; based on patch from
253 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
254 sequence is met. Before the error was not set so it would be unknown.
256 Adjust yaz-marcdump MARC reader so that it skips until record separator
259 --- 2.1.52 2007/03/07
261 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
262 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
263 fd_set structure used as a bitmask for the FDs to be selected on.
265 Using ACX_PTHREAD macro to check for POSIX threads.
267 Fixed have-vsnprintf check.
269 --- 2.1.50 2007/02/23
271 Fixes for configure on BSD. Bug #900.
273 Added snprintf/vsnprintf wrappers for systems that don't have
274 limits (heavens forbid).
276 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
277 created before all previous tasks were completed and removed from the
278 task queue, the new task could be removed by a mistake.
280 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
282 Implemented pass-through CQL-to-PQF conversions. Bug #861.
284 Fixed bug #832: Problem with MARC/charset in yaz-client.
286 Fixed bug #668: save command line history for yaz-client.
288 Fixed bug #830: pkg-config support.
290 --- 2.1.48 2007/01/23
292 Extended ZOOM result set options with two options that may be read by
293 a client: resultSetStatus and presentStatus with values as specified for
295 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
297 Fixed bug #827: Using SSL fails on Debian etch.
299 Fixed bug #826: Weird looking chars for set of MARC records.
301 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
302 that is treated as an ItemOrder with itemRequest being an XML document
303 external. The value of "doc" is the content.
305 Extended the GFS search facility. New member of bend_search_rr
306 'estimated_hit_count' signals that hits is known to be an estmate
307 (higher or lower than real hit count). New member 'partial_resultset'
308 signals that the search was partial (hit count is lower or equal than
309 real hit count). For Z39.50, the information is stored in resultSetStatus
310 member of SearchResponse APDU. For SRU, the information is signalled
311 via SRU diagnostic 59: "Result set created with valid partial results
314 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
316 --- 2.1.46 2007/01/13
318 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
320 Added ZOOM_connection_peek_event.
322 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
323 the following new functions:
324 ZOOM_event_nonblock, ZOOM_connection_process,
325 ZOOM_connection_get_{socket,mask,timeout},
326 ZOOM_connection_fire_event_{timeout,socket}.
327 The existing blocking event handler, ZOOM_event, is a wrapper for the
328 + blocking ZOOM_event_sys_{poll,select}.
330 Implemented function ccl_xml_config which parses XML version of CCL
331 configuration (bug #798).
333 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
335 Added timings utility (yaz/timing.h)
337 --- 2.1.44 2007/01/03
339 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
342 Fixed bug #779: Rotation of apdu.log fails.
344 Fixed for character set conversions:
345 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
346 Honor G1 set in MARC-8 decoding.
348 --- 2.1.42 2006/12/17
350 Fixed bug #775: char conversion does not handle Alternative UTF-8
353 Implemented function yaz_marc_read_line which parses MARC line format
354 records. There is a wealth of formats out there. So far, this function
355 reads line records produced by yaz_marc_write_line.
357 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
358 more generic and easier to remember(!) options: -i format and -o format
359 which specifies input format and output format respectively - where
360 format is one of "marc", "marcxml", "line", "marcxchange".
362 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
363 does not print anything except warnings for records.
365 For yaz-marcdump, added support for MARC split into files (-s) with a given
368 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
369 spec, at http://www.loc.gov/standards/sru/record-update/
370 This has changed the binary layout of the following structs:
371 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
372 bend_update_rr . Patch by Ko van der Sloot.
374 Added GFS utility function bend_assoc_is_alive which returns 1 if
375 association is still alive (client is connected); 0 otherwise (client
376 closed connection). This allows busy servers to stop working for
379 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
380 been a separate piece of software. This version of ziffy has been modified
381 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
383 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
385 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
386 Client code may now interrogate options such as "init_opt_sort" to
387 find out whether the server claims to support various options.
389 --- 2.1.40 2006/11/27
391 Added utilities yaz_{set,get}_esn to set/get element set name from
394 Removed the build of libyazthread.la. The libyaz.so is the threaded version
395 of YAZ and has been so since YAZ 2.1.10.
397 Implemented ZOOM_record_error which returns error information for
398 record (surrogate diagnostic).
400 --- 2.1.38 2006/10/31
402 Updates for SRU Update by Ko van der Sloot:
403 1. Changed name from "operation" to "action"
404 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
405 versions in the code, marked as 'backward compatible'.
406 3. Added diagnostics for SRU Update.
408 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
410 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
412 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
414 For GFS, fixed problem with SRU diagnostic 'First record position out of
415 range' being issued for 0 hits.
417 zoomtst10 part of Windows Build.
419 --- 2.1.36 2006/10/13
421 Implemented yaz_filepath_comp which splits a path into file path
422 components (required by Zebra 2.0.3+).
424 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
425 BSD inspired license until now so this should not have any real impact on
426 anybody. See http://www.opensource.org/licenses/bsd-license.php
428 Fixed bug #687: Missing log lines.
430 Fixed bug #678: CQL to PQF translation does not preserve double-quote
433 Fixed bug #689: SRU diagnostics to be added.
435 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
436 whether a connection is idle (no more work do do).
438 --- 2.1.34 2006/10/04
440 Change type of optval from long to int for invocation of setsockopt with
441 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
443 Added support for specifying the max log file size for the Generic
444 Frontend Server. The size is given with option -r.
446 --- 2.1.32 2006/09/21
448 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
450 --- 2.1.30 2006/09/17
452 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
455 Fixed bug in Generic Frontend Server that could cause a server to stop
456 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
458 For the generic frontend server, the maximum record size is used as maximum
459 size of incoming packages (SRU + Z39.50). The value until was previously
460 only used in Z39.50 Init negotiation and, later, in a session controlled
461 sizes of records returned. This is controlled using -k option. It can be
462 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
464 --- 2.1.28 2006/09/04
466 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
469 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
471 New option for yaz-marcdump -lpos=value which allows setting a portion
472 of MARC header to a certain value.
474 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
476 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
477 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
479 --- 2.1.26 2006/08/15
481 Fixed problem with SRU mode type (soap, get, post) for yaz-client
484 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
486 --- 2.1.24 2006/08/08
488 Fixed MARC ISO2709 encoding routines to deal with character set
491 Minor changes to GFS logging. Database included in search request log
494 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
495 cached/multiple records.
497 Shared libraries are built by default on Unix+configure.
499 Changed cql2pqf transformation to use a different evaluation order. The
500 new order is: always, relation, structure, position, truncation, index
501 and relationModifier. Old order was: always, relation, relationModifier,
502 structure, index, position, truncation. Note that the the latter ones
503 override former ones for identical attributes.. The new scheme means that
504 it is possible to override any existing attribute with a relationModifier.
505 And also that it is possible to override everything for the index rule
506 (except the ones listed in relationModifier). No order is perfect but this
507 one, we believe, covers more real cases.. The "always" should have been
508 called "default", since the attributes there can be overridden with all
511 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
512 compilation phase, but also for yaz-config --cflags output. This allows
513 us to have public headers with Libxml2 stuff in them . It should also,
514 eventually, make Libxml2 checks redundant in packages using YAZ, such
517 --- 2.1.22 2006/06/15
519 Changed SRU update structure bend_update_rr so that SRU diagnostics are
520 stored in uri, message and details.. Previously diagnostics were stored
521 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
522 compatibility.. but he's probably the only one affected, so.
524 Added support for CCL, compiled on the client side, in ZOOM-C. This
525 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
526 input; the resulting query objects can be used for for searching with
527 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
529 YAZ' configure searches for OpenSSL by default.
531 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
532 SL_CTX_use_certificate_file. See
533 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
534 for more info. Thanks to Ko van der Sloot.
536 --- 2.1.20 2006/06/02
538 Bug #600: SRU GET, POST support for yaz-client. Introduced
539 command 'sru' which selects method SOAP/GET/POST.
541 Allow missingValueAction to be specified for the sortspec string -
542 function yaz_sort_spec. By default, the missing value action is null.
543 Use ! to specify "abort". Use = followed by stringvalue to specify default
546 Ensured that Present-handler (if defined) is called in GFS before any call to
547 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
548 searchRetrieve requests.
550 Documentation for YAZ is now based on the Docbook XML/XSLT using
551 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
552 is no longer depending on jade/openjade or docbook-to-man scripts.
553 PDF is no longer part of the distribution - but can optionally be
554 made using DSSSL/jadetex or FOP.
556 Added retrieval handling support in Generic Frontend Server to support
557 conversion between MARC/XML as well as XSLTtransforms. See
558 etc/yazgfs.xml for an example.
560 Added Authentication support to Generic Frontend Server in SRU
561 mode. Authentication using HTTP Basic is supported, as is the use
562 of 'x-username' and 'x-password' parameters in the request itself.
564 Added support for a new character set MARC8s identical to MARC8 except
565 that it converts combined characters to single Unicode characters in the
566 Latin-1 range (when possible).
568 --- 2.1.18 2006/04/24
570 ASN.1 compiler 0.4: generates brief Doxygen file header for
571 generated .h/.c files.
573 Utility yaz_iconv now supports conversion to MARC-8.
575 New facilities for the MARC module. The reading - and writing of
576 content are separate methods for the yaz_marc_t handle. The following
577 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
578 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
579 format). Write functions have prefix yaz_marc_write_.. The existing
580 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
581 available. Removed support for OAI-MARC and simplexml (not the
582 simplexml from PHP5).
584 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
585 to be returned for this connection.
587 --- 2.1.16 2006/03/31
589 Allow multiple languages and charsets to be specified with
590 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
591 negcharset iso-8859-1,utf-8
593 Translation of proximity nodes from CQL into PQF now works.
595 Moved to automake 1.8, 1.9.
597 Added function yaz_log_set_handler which allows a log handler to be
598 installed. This handler will be called for all log messages. Output
599 to file is also produced; but that can be disabled by passing NULL
600 fname to yaz_log_init_file.
602 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
604 For SRW (including GFS), accept application/soap+xml as content-type
607 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
608 produces NO stylesheet reference even if a default stylesheet is specified
611 --- 2.1.14 2006/03/14
613 Updated Windows package to include yazd.dll + yazd.lib for the
614 Development component.
616 If the environment variable YAZ_LOG is set, then it is used as a
617 string indicating the default level of logging to use if not
618 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
619 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
620 used as before. So, for example, to omit warnings from YAZ logging,
623 cql_transform() now map structure and other attributes before indexes,
624 so that index-specific structures and other attributes can override
625 defaults. So now a combination of mapping specifications such as:
627 index.dc.date = 1=date-modified 4=5
628 does the right thing.
630 cql_transform() now also respects the "always" mapping specification,
631 which establishes an initial set of attributes to be used for all
632 terms except where overridden by more specific attributes associated
633 with the index, relation or modifier.
635 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
636 which mode to use; one of "post", "get" or "soap" (SRW, default).
638 Fixes for yaz_iconv routines: changed trie-based character set conversions
639 to use only non-negative values for bit fields due to Sun's C compiler not
640 supporting negative values.
642 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
643 sequences where not read correctly. Fix by Rustam Usmanov.
645 Updated win/makefile to use options, settings which makes things
646 compile with VS C 2005.
648 --- 2.1.12 2006/02/01
650 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
652 In ZOOM socket code, use select instead of poll on MacOSX.
654 ZOOM-C now support client-side compilation of CQL into RPN that is
655 sent to the server, enabling CQL to be used against all Z39.50
656 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
657 ZOOM_query object, and submit it using ZOOM_connection_search().
658 The CQL-to-RPN translation uses a configuration file, the name of
659 which must be specified in the Connection's "cqlfile" option.
661 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
662 function, which takes as its start-term parameter a ZOOM_query object
663 (which may have had either CQL or RPN set into it).
666 --- 2.1.10 2005/11/29
668 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
669 GFS to support this as well. Backend handler, bend_srw_update, does the
670 update work. Code contributed by Ko van der Sloot.
672 Allow retrieval of Search Result-1 information in ZOOM by the use of
673 options that are attached to a result set. ZOOM documentation updated
676 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
677 UTF-8 conversion. Patch by Raj Patel.
679 Added option -m to GFS to control formatting of timestamps in log file.
681 Added 'exit' as synonym for 'quit' in yaz-client
683 Added support for specifying SRW resultSetId + resultSetIdleTime in a
684 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
685 for the new members. Patch by Ko van der Sloot.
687 Added support for SRU POST. It is supported for content-type
688 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
690 Do not build the separate Multi-threaded (MT) library libyazthread.la.
691 Instead make the library libyaz.la multi-threaded. Threading as a whole
692 can still be disabled by configure option --disable-threads. Previosly,
693 with older GLIBCs there were problems with MT libs under Apache. This
694 has now been fixed a long time ago.
696 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
699 CQL module modified to be case insensitive for relations/indexes/operations.
701 Fixed bug in CQL transform code: incorrect value relationModifieder
704 Added 'show all' command for yaz-client which retrieves all results
707 Added new yaz-client, xmles, which takes a (private) OID and
708 a document to be sent as an extended service request.
710 Describe new yaz-client commands wait_response and set_auto_wait.
712 Increase TCP/IP listener backlog from 3 (which I am guessing was
713 copied from the SunOS manual entry way back when) so SOMAXCONN, so
714 that the socket will queue as many incoming connections as it's able
715 to handle ongoing connections. In other words, it will never now
716 refuse a connection that it would be able to handle merely because
717 it's not got around to accepting() enough of the pending connections
718 yet. This is the behaviour anyway under Linux, where the listen()
719 argument is ignored; but not under BSD and on systems such as
720 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
721 YAZ-based servers should now be uniform across operating systems in
724 yaz-marcdump uses 64-bit file access on some systems. This is enabled
725 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
726 This allows yaz-marcdump to read large MARC batches (>2 GB).
728 Modified all YAZ source files - except the source which is auto-generated
729 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
732 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
733 corresponding to the existing *_setl() function. These allow option
734 values containing arbitrary valuues.
736 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
737 ZOOM_resultset_sort() in new applications. Its behaviour is identical
738 except that it returns an indicator of whether or not the sort
739 criterion was accepted (0 for OK, -1 for invalid).
743 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
744 MARC output rather than returning "new" buffer.
746 yaz-client warns about unknown init options.
748 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
752 Added support for SRW sort in Generic Frontend Server. Patch
753 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
754 sortKeys - or NULL if none is provided.
756 Fixed bug #307: It was impossible to specify indefinite/no timeout
757 for ZOOM_event. Special timeout value -1 now means indefinite timeout
760 Added support for multiple languages and charsets to be specified in
761 ZOOM. Each charset/language is separated by a blank. If negotiation is
762 in effect in init-response, Option
763 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
764 Code based on patch by Vasiliy Osadchuk.
766 Fixed bug #306: infinite recursion that occurred when calling
767 yaz_log_level_init as the first call (before other log level or
770 Fixed bug in scan handling in front end server: if preferred-Position-In-
771 Response was non-present, a NULL pointer referece was performed.
775 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
776 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
777 now defined for all those error codes. So instead of putting 109 in
778 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
779 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
781 Modified the yaz-marcdump utility to skip garbage bytes between MARC
784 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
786 Program yaz-client now exits and produces an error message if multiple
787 Z39.50 servers are specified on the command line (none or one allowed
790 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
795 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
797 Fixed bug #272: Preserve spacing for CCL terms.
801 Added support for virtual hosts and multiple backend servers for
802 the YAZ frontend server. The configution is XML based and
803 support specificition of CQL to RPN mappings and explain information.
804 See section "Virtual Hosts" in the YAZ manual.
806 Extended OPAC display utility. OPAC display utility renders
807 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
808 to supplement yaz_marc_decode_wrbuf.
810 Fixed a bug in MARC decoder that could caused it to crash for some
811 invalid MARC records. More diagnostics and warnings where added in
812 XML output (warnings, etc are stored in comments).
814 --- 2.0.34 2005/02/08
816 Fixes for UNIX domain sockets. Bug #261.
818 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
820 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
821 Added yaz_marc_subfield_str which defines subfield lead string which is
822 used in YAZ_MARC_LINE format. Default string is blank+$. Added
823 yaz_marc_endline_str which defines end of fields string used in
824 YAZ_MARC_LINE format. Default string is newline.
826 Experimental support for MarcXChange. This format can be produced
827 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
828 http://www.bs.dk/standards/MarcXchange.xsd
830 Added yaz-client commands scansize that sets maximum number of
831 entries to be returned by scan.
833 --- 2.0.32 2005/01/11
835 Added support for SRW scan in yaz-client and Generic Frontend Server.
837 * Added whereInList member to SRW Scan Term.
839 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
841 Fixed NMEM system to return aligned blocks on the smallest boundaries
842 that are suitably aligned for all possible types on the particular
843 architecture YAZ is being built for.
845 --- 2.0.30 2005/01/04
847 Fixed numerious warnings that was issued with newer versions of GCC.
849 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
850 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
853 Make YAZ Generic Frontend Server slightly faster.
855 Enhance (and reduce) logging for Generic Frontend Server.
857 Revert YAZ log system so that it flushes every write operation
858 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
860 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
861 instead of LOG_, due to name clash with syslog(3). LOG_ are still
862 present. New applications should define YAZ_USE_NEW_LOG=1 - this
863 will effectively disable old definitions.
865 --- 2.0.28 2004/11/09
867 Added yaz_log_time_format which specifies log format using
870 Added yaz_log_module_level which returns mask for a module. Value
871 is non-zero mask a if module is enabled; zero if disabled.
873 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
874 in include/yaz/cql.h.
876 Fixed bug #176: Dont throw diagnostics on empty SRU args.
878 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
880 Fixed bug #172: RPM builds does not enable SSL.
882 Doxyfile.in part of dist. Doxyfile generated by configure.
884 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
885 are given and the corresponding component does not exist.
887 Extend CCL documentation in YAZ reference. Describe r=r.
889 --- 2.0.26 2004/10/01
891 Fixed MARC->MARCXML conversion to properly deal with
892 fields, subfields, indicators having non-ASCII characters.
894 Fixed MARC->MARCXML conversion so that ASCII control characters
895 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
898 Added YAZ GFS support for conversion from Z39.50 surrogate
899 diagnostics to SRW surrogate diagnostics.
901 Bug fix: YAZ GFS did not return schema in explainResponse.
903 --- 2.0.25 2004/09/30
905 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
906 now converts recordSchema to elementSetName as well as schema URI.
908 Fixed bug in COMSTACK that prevented HTTP request packages from being
911 --- 2.0.24 2004/09/29
913 Added CCL facility r=r "range" which is similar to r=o "ordered" but
914 does not require white-space before and after the dash in a range, e.g.
915 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
918 Fixed a few AC_TRY_LINK configure tests that did not operate properly
919 due to new GCC removing "redundant" code.
921 Added yaz-client commands scanpos and scanstep that sets preferred
922 position and step-size for scan.
924 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
926 Added CCL utility ccl_qual_buf which parses one or more CCL
927 spec lines in a buffer.
929 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
930 of name and value - ignoring empty lines and comments.
932 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
934 Added odr_get_element_path which returns current element path for an
935 ODR handle. This utility is useful in error handling or user-defined
938 Added ODR_PRINT utility odr_set_stream which is is a more generic
939 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
940 to a write function and pointer to close function. The close function - if
941 non-NULL - will be called during odr_destroy.
943 Fixed bug in CCL parser where truncation char was not removed from
944 right side when truncation=both was in effect.
946 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
949 --- 2.0.23 2004/08/11
951 Fix buffer overrun in CQL parser when dealing with proximity (%).
953 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
954 to UTF-8/UCS conversion is now only based on codetables.xml.
956 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
958 --- 2.0.22 2004/08/06
960 Add support for more "commit changes" in ZOOM (uses Extended Services).
962 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
965 Yet another small fix for configure of SSL.
967 --- 2.0.21 2004/05/14
969 Fix SSL libs for configure when --with-openssl=DIR is given.
971 --- 2.0.20 2004/05/10
973 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
975 SSL comstack now uses yaz.pem certificate file on server side
976 by default. Certificate filename can be configured by calling
977 comstack function cs_set_ssl_certificate_file before cs_bind is used.
979 Fix bug regarding multiple calls to ZOOM_connection_connect.
981 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
983 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
984 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
986 ZOOM now allows inspection of X509 peer certificate for verification.
987 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
989 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
990 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
991 as "modular" but it simplifies things.
993 Added cs_get_peer_certificate to that returns peer X509 PEM.
995 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
996 NULL if SSL is unavailable.
998 Documentation about MARC decoding tools.
1000 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1002 --- 2.0.19 2004/03/30
1004 Rename CHANGELOG to NEWS to follow GNU style packing.
1006 Fix bug with missing initialization of member in init_diagnostics.
1007 This bug affects threaded version of GFS server.
1009 --- 2.0.18 2004/03/20
1011 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1014 Ensure zlib.dll is packed with Windows install.
1016 --- 2.0.17 2004/03/17
1018 Fix encoding of xsd:string to use text instead of CDATA.
1020 Fix endless loop in CQL parser with unbalanced ".
1022 Use a more compact way to store MARC-8 conversion tables.
1024 --- 2.0.16 2004/03/16 Debian only
1026 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1029 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1034 --- 2.0.15 2004/03/01
1036 Another fix for decoding of XML packed records.
1038 --- 2.0.14 2004/02/25
1040 Fixes for Chunked encoding. White space not ignored after length spec.
1042 Update NS and use default NS for SRW diagnostic elements.
1044 --- 2.0.13 2004/02/23
1046 Implement ZOOM_resultset_cache_reset which resets record cache.
1048 Implement ZOOM_resultset_sort which sorts a result set.
1050 Implement chunked HTTP transfer.
1052 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1054 --- 2.0.12 2004/02/16
1056 Added member 'schema' to bend_explain_rr structure so that backend
1057 can specify explain record identifier. Defaults to Zeerex 2.0.
1059 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1061 --- 2.0.11 2004/02/16
1063 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1066 Added init command for yaz-client which sends "extra" init request.
1068 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1069 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1071 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1073 Make ZOOM error code for "invalid query".
1075 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1077 --- 2.0.10 2004/02/05
1079 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1082 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1084 Added option -p <file> to make Generic Frontend Server to write PID file.
1086 Added option -D to put Generic Frontend Server in background on its own.
1088 Make ZOOM C recognize option "password". If unset, "pass" is used
1089 (for backwards compatibility).
1091 Fixed a bug in Generic Frontend Server that could make it crash if a
1092 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1095 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1096 Must be issued before open, in order to be in effect.
1098 --- 2.0.9-6 2004/01/12 Debian/Windows
1100 Make the SRU server more picky WRT unknown params, etc.
1102 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1104 New YAZ client command, options, that sets Z39.50 options.
1106 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1107 options from a string of tokens (one token for each option bit).
1109 Update SRW diagnostic code messages.
1111 --- 2.0.9-5 2004/01/07 Debian/Windows
1113 Handle user defined stylesheet for SRW/SRU.
1115 --- 2.0.9-4 2004/01/06 Debian/Windows
1117 Fix bug in decoding of Content-Length.
1119 --- 2.0.9-3 2004/01/06 Debian/Windows
1121 Fix a bug with decoding of XML packed records.
1123 --- 2.0.9-2 2004/01/05 Debian only
1125 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1127 Fix bug in SRW/SRU diagnostics decoding.
1129 --- 2.0.9 2004/01/05
1131 Fixed bug in Generic Frontend Server which could drop records exceeding
1132 preferred message size. Reported and fixed by Irina Dijour.
1134 Fixed calculation of package size for structured records in Generic
1135 Frontend Server. Reported and fixed by Irina Dijour.
1137 Fixed namespace for SRW/SRU diagnostics.
1139 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1141 --- 2.0.8 2003/12/22
1143 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1144 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1147 CQL changes to reflect recent changes to the specification:
1148 * Documentation talks about context sets instead of index sets.
1149 * Documentation talks about indexes instead of qualifiers.
1150 * The CQL-to-PQF transformer's configuration file now uses
1151 "index.set.name = <attributes>" instead of the old form
1152 "qualifier.set.name = <attributes>". (Both forms are still
1153 understood but the latter is deprecated.)
1154 * CQL terms with no explicit index specified are now interpreted as
1155 cql.serverChoice instead of srw.serverChoice (which of course
1156 behaves exactly the same.)
1158 --- 2.0.7 2003/12/16
1160 MARC conversion can now generate ISO2709 output in another
1161 character set. yaz-marcdump uses this facility if you invoke it
1164 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1165 functions from there can be used from C++.
1167 --- 2.0.6 2003/12/04
1169 Frontend server now transfers memory from decoded packages to stream
1172 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1173 references to show up.
1175 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1176 the ZOOM Abstract API. The older names for the same options are still
1177 also supported for the benefit of old applications.
1179 ZOOM-C supports "implementationId" and "implementationVersion" options
1180 to go along with "implementationName". These allow the user code to
1181 specify identification strings to be sent to servers.
1182 Add OID for the new ExtLite attribute set.
1184 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1185 as requested/supplid by Ere Maijala <ere@atp.fi>
1187 For generic frontend server, reverse the order of
1188 "toolkit-supplied / application-supplied" strings sent as implementationId,
1189 Name and Version. Also, remove the spaces around the slash. This brings
1190 the GFS in line with the behaviour of ZOOM-C on the client side.
1192 Add function ZOOM_scanset_display_term.
1194 yaz-client shows scan displayTerm if present.
1196 Utility yaz-iconv is now installed by default along with the man page
1199 Extend configure check for OpenSSL to use pkg-config where available (such
1202 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1203 server to specify uid/gid/mask for socket using the format
1204 unix:[user=uid,][group=gid,][umask=mask,]file=path
1205 If file= is omitted the existing format is assumed, e.g.
1207 in which case the mask is 0666 (rw for everybody).
1209 Major restructure of YAZ source. All source in libyaz is in src directory.
1210 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1211 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1213 Added man page for utility yaz-marcdump (used to be called marcdump).
1214 yaz-marcdump is installed by 'make install'.
1216 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1217 of incoming package failed.
1219 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1221 Change prototype of odr_perror: add const to message string.
1223 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1225 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1226 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1227 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1228 DNS lookup. There should not be any compatibility problems with this
1229 assuming that blocking=1 or 0 is used.
1231 Fix bad reference in UNIX comstack in function cs_addrstr.
1233 Fix for compilation on AIX.
1235 The generic front-end server (server/seshigh.c) now supports returning
1236 Init diagnostics to the client in User-information-field, in
1237 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1240 --- 2.0.4 2003/09/04
1242 Allow any CQL relation (not just all,any,exact,scr).
1244 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1245 that features the same UI.
1247 Implemented command update0 in YAZ client which is equivalent to
1248 update but uses old of Ext Update ASN.1.
1250 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1251 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1252 Previously no OID was used for this info.
1254 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1255 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1256 returns 'malformed search term' otherwise.
1258 SortResponse member resultCount now set to NULL in sort handler of
1261 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1264 Add three new utility functions for translating OIDs between various
1265 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1266 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1267 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1268 char *oid_to_dotstring(const int *oid, char *oidbuf);
1269 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1271 Reverted modifications for ES Update definition for z_IU0Update
1272 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1273 is back to YAZ 2.0.2.
1275 String value attributes for CCL parser.
1277 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1278 which their FirstSearch server returns in Init responses, sometimes
1279 carrying useful diagnostic information when Init fails. This has the
1280 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1281 "z39.50/oclcui.asn", where its definition is somewhat different from
1282 what OCLC document on their web-site, as required to interoperate with
1285 Support for anonymous authentication in yaz-client. Use the command
1288 * Fix the OID of the Index Data-local "admin" Extended Service from
1289 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1290 the 1000, which indicates a locally-defined OID, was a mistake.
1292 --- 2.0.3 2003/06/20
1294 Fix CCL directive @case handling so that it affects string match for
1295 both CCL keywords and qualifiers.
1297 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1298 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1299 Decoder has been updated with ASN.1 changes as listed in
1300 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1301 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1302 z_IUUpdate, remains unchanged.
1304 ZOOM_record_get may now return a record in a specific character set.
1305 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1306 "from" is the character set of record as returned by target. "to" is
1307 the character set to be returned. If omitted, "to" is UTF-8.
1309 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1311 New ODR utility, odr_getelement, which returns name of element for
1312 which encoding/decoding failed.
1314 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1315 in cases where a required element was omitted.
1317 Bug fix: some MARC8 sequences were not converted.
1319 New ZOOM option "step" which specifies number of records to be
1320 retrieved in one chunk. Used in conjunction with "start" and "count".
1322 SRW support for yaz-client. Use scheme http: to use it, e.g.
1325 yaz-client no longer does (un)intelligent character set conversions
1326 by default. Can be enabled with charset and marc_charset commands.
1328 xmalloc trace fix for 64-bit systems such as DEC alpha.
1330 Solaris 2.6 compile fix.
1332 New function, cql_strerror() translates SRW error codes, as returned
1333 by cql_transform_error(), into human-readable English strings. Used
1334 in yaz-client diagnostics when appropriate.
1336 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1337 converts it into a type-1 query which is sent to the server. This
1338 makes CQL available for use with all Z-servers, as opposed to the tiny
1339 minority that can handle CQL queries themselves.
1341 --- 2.0.2 2003/04/28
1343 New Debian package layout similar to the Redhat Package layout.
1345 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1346 and search result respectively.
1348 --- 2.0.1 2003/04/25
1350 Redhat package is now several packages: libyaz (runtime libraries),
1351 libyaz-devel (development and documentation, and yaz (utility programs).
1352 Package spec file by Morten Bøgeskov.
1354 New member 'schema' in struct bend_fetch_rr which the name of requested
1355 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1356 handler MAY set this to reflect the schema of the returned record.
1358 New member 'display_term' in struct scan_entry. GFS now sets member entries
1359 and allocates scan entries to be filled by user scan handler. In previous
1360 version, entries member was allocated by the scan handler. That still works,
1361 but the GFS will ignore member display_term - assuming it was NOT set by
1362 the handler. The fact that the GFS now allocates the entries both allows
1363 for new members and makes a scan handler easier to write.
1365 Fix CQL lex buffer overflow.
1367 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1368 SRU default recordPacking is string.
1370 SRU protocol support for frontend server.
1372 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1374 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1376 Added scan for the ZOOM shell (zoomsh).
1380 * String Identifers for Schemas (Amendment 5).
1381 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1382 Old definition for schema
1383 Odr_oid *schema; /* OPT */
1388 Z_InternationalString *uri;
1389 #define Z_Schema_oid 1
1390 #define Z_Schema_uri 2
1393 * resultCount parameter to Sort Response (Amendment 1).
1394 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1396 Support for SRW 1.0 over HTTP. This is an optional feature and
1397 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1400 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1401 on the same port. SRW SearchRetrieveRequests are mapped
1402 to bend_init,bend_search,bend_fetch,bend_close.
1404 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1406 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1407 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1409 ZOOM connections are SRW based if schem http is used for hostname
1410 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1411 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1413 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1414 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1415 distance=n, order=true/false, relation=le, prox unit=word. If
1416 n is omitted, distance 1 is used.
1418 Fixed problem with C compiler include path in wrong order.
1420 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1421 on Solaris. Patch from Ko van der Sloot.
1423 New MARC decode API. All new functions operate on a yaz_marc_t
1424 handle. The most important new functions are: yaz_marc_create,
1425 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1426 decode and destroy respectively. Decoder can produce formats
1427 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1428 include/yaz/marcdisp.h.
1430 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1431 to UTF-8, UCS-32, wchar_t or Latin-1.
1433 * Prototypes for yaz_iconv_-functions moved to separate header
1434 include/yaz/yaz-iconv.h.
1436 Make a few private functions 'static' in unix.c. This prevents
1437 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1439 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1440 are set when Init Response is received.
1442 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1443 but returns diagnostic set as well.
1445 New function yaz_strerror which is a portable wrapper for
1446 strerror/strerror_r/GetLastMessage.
1448 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1449 is returned for MARC. If type is "oai", then OAI MARC is returned.
1451 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1454 --- 1.9.2 2002/11/26
1456 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1458 Fix bad race conditions on SIGTERM and terminate gracefully in
1461 Move retrieval (data1) module to Zebra since nobody seems to be
1464 Add GRS-1 render for ZOOM using same format as yaz-client.
1466 --- 1.9.1 2002/10/05
1468 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1470 Fix broken ESpec handling in data1 module.
1472 SGML reader parses comments and makes them part of the data1 tree.
1474 Added several type casts so that YAZ compiles as C++ code.
1476 ZOOM didn't handle PDU encoding failures properly.
1478 Added more Bib-1 diagnostics (approved extensions).
1480 GNU configure: better check for iconv.
1482 More portable use of accept, getpeername. Check for socklen_t. Use
1483 int/size_t if socklen_t is not defined.
1487 PQF parser rejects bad queries - including those with extra
1488 characters in them. PQF parser used to silently ignore that.
1489 Cleaner API for PQF added, which allows you to get detailed
1490 error information for bad queries (see yaz/pquery.h).
1492 Fixed bug in ZOOM_record_get for type "database".
1494 Implemented mini iconv library supporting conversions between
1495 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1497 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1499 --- 1.8.9 2002/08/20
1501 Fixed ZOOM C record cache so that preferredRecordSyntax and
1502 elementSetName is used to check for already fetched records.
1504 --- 1.8.8 2002/08/02
1506 Added three members in bend_initrequest structure to facilitate
1507 character set negotiation.
1509 Fixed a bug in frontend server that could cause indefinite
1510 loops under rare conditions.
1512 Revised character set utilities (charneg.h) so that encoding
1513 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1515 For PQF, directive @term <type> sets term type for Scan/Search.
1516 Here <type> is general, string, numeric, null. The term type
1517 is inherited - just like @attr.
1519 New call odr_set_charset that sets character set conversion for
1520 international-strings on a ODR stream. Prototype is:
1521 int odr_set_charset(ODR o, const char *to, const char *from);
1522 The InternationalString is still represented as C string in YAZ
1523 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1524 won't). On the protocol level, you can use any encoding.
1526 Support for UNIX sockets in ZOOM.
1528 Solaris recv sometimes returns errno == ENOENT. It is treated as
1529 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1531 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1532 both client and server. Code by Morten Bøgeskov.
1534 --- 1.8.7 2002/05/22
1536 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1537 that they can be used directly from Visual Basic. You must recompile
1538 your windows APP if you're using ZOOM.
1540 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1541 Commands "lang" and "charset" sets language and character set respectively.
1542 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1543 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1545 Attributes from multiple CCL fields may be OR'ed rather than merged
1546 using directive "@field or". Fields are still merged by default -
1547 equivalent to "@field merge".
1549 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1552 Fixed bug in zget for parameter ExtendedServicesResponse.
1556 --- 1.8.6 2002/03/25
1558 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1560 Client displays USR.1:SearchResult-1 (hits per term).
1562 Additional Search Info for search in Generic Frontend Server.
1564 Fixed CCL parsing of "field=s".
1566 WIN32 installer - using the excellent NSIS software from nullsoft.
1568 Fixed CCL parsing of "field = - <number>".
1570 Added function yaz_marc_decode that decodes MARC for line mode
1571 display or XML (similar to that used by JZKit).
1573 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1574 Z39.50. But ISO/ILL was, however.
1576 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1577 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1579 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1580 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1582 --- 1.8.5 2002/02/03
1584 New YAZ client features: Command completion and new commands:
1585 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1586 Code provided by Jacob Poulsen.
1588 New call oid_trav, that visits all registered OIDs via callback.
1590 Function ZOOM_record_get now returns const char pointer rather than
1591 void pointer. It saves a lot of type casts.
1593 For YAZ client, command "auth" now allows you to set authentication
1594 in IdPass style. It is enabled when three tokens are given - order
1595 is user, group and password.
1597 Fix memory leaks in MARC record handling for ZOOM.
1599 New option for YAZ client, -k <kilobytes> that sets
1600 maximum record size. Similar to -k option for generic frontend
1601 server and yaz-ztest.
1603 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1605 Prefix query parser reports "fail" when bad attribute set is given.
1607 Fix in MARC decoder. Proximity logging. Fix for attribute set
1608 in scan handler for server. Patches by Shigeru Ishida.
1610 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1613 Configure option --with-openssl=<dir> now works when a directory is
1614 specified. Patch provided by Morten Bøgeskov.
1616 New option for YAZ client, -u <auth>, that sets authentication.
1618 ZOOM fix: error information was sometimes "missing", since error
1619 was cleared/reset too when it shouldn't.
1621 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1623 --- 1.8.4 2002/01/04
1625 Scan for ZOOM API. New object ZOOM_scanset. New functions
1626 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1627 ZOOM_scanset_destroy.
1629 New ZOOM function, ZOOM_connection_last_event, that returns type
1630 of last event (such as "receive data", "send data", "apdu received",
1633 New ZOOM option, schema, that specifies schema for retrieval.
1635 New CCL feature. Qualifiers can be aliases for one or more
1636 other qualifiers (if more than one is given, OR is used).
1638 ZOOM uses named result sets if target supports it.
1640 Two new YAZ client commands: . (dot, which sources a script of YAZ
1641 client commands), and ! (to execute shell command.). Implemented
1644 Working on Debian packages.
1646 --- 1.8.3 2001/11/19
1648 YAZ client enables named result sets only if target supports it.
1650 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1652 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1653 with key="host" to get same result.
1655 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1656 Function Z3950_resultset_record(s) returns references to records
1657 "owned" by resultset. To become owner use Z3950_record_clone.
1659 Function z_ext_record handles Extended Services. Thanks to
1662 --- 1.8.2 2001/11/12
1664 CCL Parser fix: ignore token comma when dealing with and-lists.
1666 Documentation updates for COMSTACK.
1668 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1669 Changed prototype Z3950_records. For some functions, int parameters
1670 were changed to size_t.
1672 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1675 New MARC decode/display function, marc_display_exl, which properly rejects
1676 non-ISO2709 records. YAZ client uses it.
1678 --- 1.8.1 2001/10/29
1680 Fix bug: local attribute set wasn't set correctly in PQF strings.
1684 * Old Z39.50 codecs no longer supported.
1686 Added ZOOM C binding. See http://zoom.z3950.org/
1688 Renamed states for COMSTACKs to avoid confusion with events.
1690 Implemented cs_look and proper cs_rcvconnect.
1692 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1694 Configure detects POSIX threads on OpenBSD.
1696 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1697 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1699 When error is returned from present handler, non-surrogate diagnostic
1700 is returned in present response (and fetch handler is no longer called).
1702 * Minor adjustments to pquery parser (PQF). Token characters may be
1703 escaped by using backslash (C-style).
1705 PQF parser allows string attribute values to be specified. For @attr,
1706 non-numeric characters after the equal-sign are treated as strings
1707 (e.g. @attr 9=title).
1709 CCL trunction character may be defined (@truncation in file)
1711 * function zget_ExtendedServicesRequest sets waitAction to
1712 waitIfPossible (was wait).
1714 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1717 CCL operator names may be set in field definition files (CCL_bibset).
1718 See ccl/bib1 for an example.
1720 Fixes in ASN.1 compiler for C++ compatibility.
1722 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1723 and "op_or" to avoid conflict with C++.
1725 Fixed problem with GNU readline detection on Redhat 7.0.
1727 Added step-size for Scan backend handler.
1729 Fixed bug that made the frontend server crash when no attribute
1730 set was specified for scan.
1732 Front-end server automatically switches to original working directory
1733 when installed as an NT service. Previously -w had to be specified to
1736 Added extended attributes for retrieval module (data1), so that data1
1737 records carry d1_readXML/SGML attributes. d1_read also supports
1738 null-data rules ( <tag/>)
1740 On UNIX when POSIX threads are available, a separate library libyazthread
1741 is created. Programmers should link with that library and the yaz library
1742 when using threads. The reason for the split was that some applications
1743 on Linux, such as Apache, doesn't work well when using shared objects that
1746 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1747 (or any frontend server) in SSL mode by specifying ssl: followed by
1748 address. Only tested on UNIX.
1750 Added feature for CCL module. Virtual structure s=al or s=ol generates
1751 and-list and or-list respectively instead of phrase search.
1755 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1756 log_mask_str. This was done to avoid name conflicts with other libraries
1757 (such as other PHP extensions).
1759 Added raw OID member for preferred record syntax (request_format_raw)
1760 and returned record syntax (output_format_raw) for backend fetch method.
1762 Config file yaz-config now accepts options so that it returns specific
1763 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1765 Shared library support for UNIX using GNU libtool.
1767 * Modified backend interface. Request/Response struct's replaced by
1768 one read/write C struct. For example bend_fetchrequest and
1769 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1770 Every handler - even search has to be registered in bend_init
1771 handler. This means that the YAZ library no longer refers to
1772 external functions and it makes it possible to make the whole
1773 thing a single DLL/SO.
1775 Added Segment handler for backend server.
1777 Added Zmbol/Zebra administrative functions to YAZ client.
1779 Threaded frontend server on UNIX (when POSIX Threads are available).
1780 Starting the server with option -T enables multi-threading.
1784 Added configure option --enable-comp/disable-comp to control use
1785 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1786 located in sub directory asn.
1788 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1789 in ${exec_prefix}/bin along with the other programs yaz-client and
1792 GNU automake used to maintain makefiles.
1794 Added several OID's.
1796 Changed retrieval module so that we can load records with no abstract
1797 syntax defined. Tagpaths in these records are fully composed of string
1800 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1804 On UNIX, the generated makefile now supports a proper 'make install'.
1805 The prefix can be set via GNU configure to set the install location
1806 (default is /usr/local).
1808 * YAZ programs client and ztest were renamed to yaz-client and
1809 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1810 locations, such as /usr/bin,/usr/local/bin,etc.
1812 * YAZ Header files were moved from include to include/yaz. YAZ Header
1813 files are referred to as include <yaz/log.h> rather than <log.h>.
1814 The YAZ include path (-I ..) is therefore the same as before. Programmers
1815 should update their #include statements or use -Ipath/include/yaz
1816 instead. The main motivation for doing this change is that YAZ header files
1817 can be installed in "standard" locations /usr/include,/usr/local/include
1818 without introducing conflicts, since ALL YAZ header files are stored
1819 in subdirectory yaz (under /usr/include for example).
1821 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1822 rather than project/workspace files. We switched because project files
1823 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1826 Changed name of logging function, logf, to yaz_log, to prevent name
1827 clash with some math-log functions. The YAZ header log.h defines logf
1828 to yaz_log (#define) so there should be no incompatibilities by this
1831 Added bend_start/bend_stop handlers for server. These handler are
1832 called on start/stop of server. For windows they are called whenever
1833 a service is started/stopped.
1835 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1836 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1837 in util/yc.tcl. The auto-generated C code structures are, in a few
1838 cases, incompatible with the old decoders. There are differences in the
1839 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1840 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1841 The preprocessor variable ASN_COMPILED is defined when the compiled
1842 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1843 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1844 wish to use the old encoders/decoders you can specify --disable-yc
1847 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1848 version so that it supports both new - and old version of DB Update
1850 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1851 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1852 change. The name parameter can be set to 0 in which no name is specified
1853 for the construction. The macros odr_implicit and odr_explicit sets name
1854 parameter to zero for the construction involved. New macros
1855 odr_implicit_tag and odr_explicit_tag are similar to the others,
1856 except that a name parameter is added. For programmers' that don't use
1857 ODR they probably only need to change the call to z_APDU and z_External.
1859 Added access control facility by interfacing the TCP wrapper library.
1860 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1861 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1862 name of the daemon and enables the access control as specified in
1863 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1865 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1866 den Dool <H.M.vdnDool@kub.nl>.
1868 Added reference ID parameter to most functions in server API - refer
1869 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1871 Changed name of ccl library to libccl.a (was ccl.a).
1873 Fixed bug in decoder for Explain (Category TargetInfo).
1875 Added support for GNU readline in client. Thanks to Jacob Poulsen
1876 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1878 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1879 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1880 IMPLEMENTATION! This change was made to the development version before
1881 the ZIG decided to retract the amendment. If any users MUST be
1882 compatible with the original Update definition, PLEASE CONTACT US, and
1883 we will include a separate definition corresponding to the old Update
1884 ES. Note that because of the change to the ASN.1 of the
1885 TaskPackageRecordStructure we cannot define a single structure that
1886 will support both versions.
1888 * Added const modifier to buffer parameter for some ODR/BER encoding
1889 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1890 completeWAIS, odr_dumpBER.
1892 Fixed bug in client.c which caused a crash when a scanResponse didn't
1893 contain positionOfTerm.
1895 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1896 * will cause an error in a client if a non-YAZ target sends both a
1897 * list of Scan entries and non-surrogate diagnostics.
1899 Retrieval module enhancements. Tag sets may be typed in the reference
1900 to it. From the .abs-file the "tagset" directive takes a third optional
1901 integer type for the tag set referenced. From a .tag-file the "include"
1902 directive takes a third optional type as well. The old "type" directive
1903 in the tag set itself is still recognized but acts as the default type
1906 Backend interface change. Individual Scan terms returned from bend_scan
1907 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1908 in include/backend.h.
1910 Retrieval module enhancements. Multiple tag sets and attribute sets may
1911 be specified in abstract syntax specs. Revised the error/warning for
1912 logging messages reported by the retrieval module when reading the
1915 Object Identifier system (oid_..) changed. The API is backwards
1916 compatible but the oid-routines now allocates new OID's when needed.
1917 Raw OID's may be specified in oid_getvalbyname.
1919 YAZ now uses GNU configure to generate Makefile(s).
1921 * Minor changes in some of the member names of DeleteResultSetRequest and
1922 DeleteResultSetResponse. See include/proto.h.
1924 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1925 and added member 'languages' in TargetInfo (which was missing).
1927 Changed the way attribute sets are handled in the retrieval
1928 module. These are now cached, just like the abstract syntaxes
1931 Changed YAZ so that it links with compiled ASN.1.
1933 Added Explain-schema definitions and mapping routines. The following
1934 Explain categories have been implemented: AttributeDetails,
1935 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1937 Fixed minor bug in Windows version of Server Library.
1939 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1941 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1943 Added EXTERNAL: UNIverse Resource Report (non-standard).
1945 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1946 ENUMERATED and SET OF.
1948 * Added 'const' to some of the char pointer arguments for the
1949 functions, data1_read_node, data1_getelementbytagname,
1950 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1953 Fixed bug in data1_insert_taggeddata - the last_child member of
1954 parent wasn't initialised.
1956 * Changed data1_read_record and data1_read_node so that the supplied
1957 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1958 doesn't refer to any parts of the "SGML"-buffer.
1960 Fixed bug in server library (Windows version of statserv_remove).
1962 * Changed code so that it compiles as C++. The type definition
1963 of Odr_fun which is a member of Odr_arm was changed. The result is,
1964 that an explicit typecast is needed for the fun pointer when
1965 using Odr_arm - as in:
1966 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1968 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1970 Implemented the new structured date and time definition as approved
1971 by the ZIG. Added schemaId element to the specificTag in Espec-1
1972 (also approved at the last ZIG). Thanks to RVDM.
1974 Added some Object identifiers (RVDM).
1976 Changed the Update Extended Service (RVDM).
1978 Added command "refid" to client which specifies referenceId for
1979 the following requests.
1981 Implemented extended service handling for server. See ztest.c
1982 for an example as well as backend.h. New handlers are registerd
1983 in the Init handler.
1985 * Changed interface for sort in server.
1987 Added new members to statserv_options_block. It allows a server
1988 to read options from another source than just the command line. Thanks
1989 to Charles Woodfield.
1991 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1992 renamed to zboolean. Some C++ compilers complained about the name.
1994 Minor changes to gils.abs. Added index 's' (sort) on title
1995 and date/time-last-modified.
1997 --- 1.4pl2 1998/1/30
1999 Fixed bug in server library regarding inetd mode (-i). This bug
2000 was introduced by release 1.4.
2002 --- 1.4pl1 1998/1/29
2004 Added sort facility in client and backend server interface.
2006 Fixed problem with dependencies in Makefile(s).
2008 Fixed bugs for encoders/decoders of extended services and
2011 Implemented sub-tree feature for schemas. Sub-trees are
2012 referenced in *.abs-files. See explain.abs for an example
2013 of the use of this feature.
2015 Modified bib1.att; local attributes for ANY didn't include
2016 ANY itself (only affects use of the retrieval module).
2018 Fixed bug in plain SGML reader in function data1_read_node:
2019 tags with prefix "var" was incorrectly interpreted as variants.
2021 Added feature "sub-schemas" to enable references to - and definitions
2022 of - group of elements.
2024 * Removed member parent from type data1_element (in data1.h).
2026 Implemented function odr_nullval() that returns the value of
2029 * Removed member num_children from data1_node (in data1.h).
2031 Made NT service interface part of the server library. The
2032 function statserv_main uses the NT service when required and
2033 calls the statserv_start / statserv_close routines.
2035 Routine zget_SearchRequest and zget_PresentRequest fills
2036 resultSetName/Id member with "default" instead of "Default".
2038 Fixed memory leak in server. Request queue member wasn't freed.
2040 Fixed nmem_exit so that memory is freed.
2044 Revised the CCL parser utility to be thread safe.
2046 Added function, oid_ent_to_oid, to replace the function
2047 oid_getoidbyent, which is not thread safe.
2049 * Added nmem_init and nmem_exit to initialize and release
2050 NMEM resources. Function nmem_init should be called once in the
2051 initial thread before NMEM/ODR is used. statserv.c and client.c
2052 have been changed accordingly. The change was necessary to make
2053 NMEM thread safe. The NMEM memory pool is shared amongst threads
2054 in a process. Unix-based applications will still work fine without
2057 Added NT Services interface for the the Z39.50 (statserv) Server.
2058 Refer to the ztest.c source on the usage.
2060 Windows 95/NT port using MSVC5.0. Project files are included in the
2063 * Defined new 'global' handle for the retrieval (data1) system. The
2064 new handled, data1_handle, describes the state of the data1 system.
2065 This handle is passed as first argument to virtually all
2066 data1 related routines. The functions data1_create and data1_destroy
2067 creates and destroys a data1 handle respectively.
2069 Added ODR encode stream member to all backend request structures
2070 init, search, scan etc. This stream should be used to allocate all
2071 memory used for the response when thread safe operation is needed.
2073 Changed the comstack utility, cs_addstr, to be thread safe. The
2074 returned hostname string returned by the function is now part the
2077 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2078 function. The cs_straddr takes a COMSTACK handle as argument, so this
2079 function must be used after cs_create and before bind/connect.
2080 This function is thread safe.
2082 Moved test server to 'ztest' directory - generic server code still
2083 in 'server' directory.
2085 Made prefix query (pquery.c) utility thread safe.
2087 Added new function modifier YAZ_EXPORT to 'export' public DLL
2088 functions when using windows (see include/yconfig.h).
2090 Added definitions to the OID database (util/oid.c) (RVDM).
2092 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2094 Added call to ccl_rpn_delete in client program.
2096 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2097 release of RPN structure.
2099 Added support for C++, headers uses extern "C" for public definitions.
2100 With input from RVDM.
2102 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2103 Thanks to Ronald van der Meer (RVDM).
2105 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2107 Added support for private extensions to the OID database
2108 (oid_setprivateoids()). Thanks to RVDM.
2110 Added optional, physical ANY (key replication)
2112 Fixed null-reference problem in GRS-1 output filter.
2114 Proximity operator added to Prefix Query Format (PQF).
2116 In test client command "base" accepts multiple databases.
2118 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2122 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2124 Smallish bug-fixes in the new encoders/decoders (explain).
2126 Bug fixed in DeleteRequest.
2128 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2130 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2132 Added SOIF syntax (using private OID for now) to retrieval module and client.
2134 Added Update extended service.
2136 Added SearchResult-1 additional info structure.
2138 Added optional CCL (ISO8777) interpreter as separate module. Available
2141 --- 1.2 1996/6/10 (1st anniversary release)
2143 Added Summary record syntax. Lightly tested.
2145 Added OPAC record syntax. Untested.
2147 Added ResourceReport service encoders/decoders. Untested.
2149 Fixed bug in z_Unit - wrong tagging on unitSystem.
2151 Fixed bug in the DiagRecs decoder.
2153 Added options for max PDU size and session timeout to frontend-server.
2155 Added documentation of query-language parsers and other supporting utilities.
2157 [frontend-server] Added Attribute set to the bend_scanrequest API.
2159 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2160 surrogate diagnostics were generated.
2162 [retrieval] Allow multiple local values for attribute.
2164 [retrieval] Allow multiple attributes per element in .abs files. index type.
2166 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2168 --- 1.1pl2 1996/4/10
2170 Minor changes, mostly specific to Zebra's requirements (retrieval)
2174 Repaired bug in frontend server when running multiple listening
2175 endpoints in dynamic mode.
2177 z_External() now won't break if a known, ASN.1 value comes encapsulated
2178 in an octet-string. The value will pass through unmodified in an Odr_oct.
2180 Added a bit of code to the demo client to decode & display
2181 ASN.1-structured records represented in the octet-aligned branch of
2182 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2184 Added z_ext_getentbyref() to the ASN module. Doc updated.
2186 * Completed the SCAN definition in the ASN module. This may break SCAN
2187 code based on older YAZ-versions at compile-time. The fix is easy -
2190 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2191 under the SCAN definition. Remember to initialize this, server-people.
2193 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2194 that this does not extend to ODR and ASN.
2196 Comstack allows insertion of established socket (primarily for
2197 inetd-operation of servers). Doc updated.
2199 Front-end server can now start from the inetd in TCP mode. Doc
2202 --- 1.0pl4 1996/1/24
2206 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2207 the rank and record number.
2209 Adjustments to the frontend server.
2211 Fixed diagnostic BER dumper. It ignored the file argument.
2215 Various changes to retrieval module.
2217 Changed the union discriminators of the protocol files from enums to
2218 ints paired with #defines.
2220 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2223 *Changed operator in the RPN structure to 'roperator', again to avoid a
2226 Fixed problems in Explain decoders/encoders.
2228 --- 1.0pl2 1995/12/6
2230 Memory bug in log module fixed.
2232 --- 1.0pl1 1995/12/5
2234 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2236 Bug in Explain DatabaseInfo module fixed.
2238 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2242 The shift to v1.0 signals that we now consider the *core* functionality
2243 of YAZ reasonably stable (the core being more or less equivalent to
2244 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2245 tested (Explain not at all - though that will happen soonish).
2247 Minor changes to code to support Windows port.
2249 Various minor changes after we're getting to use GRS-1 & co. more.
2251 Added Espec-1 format.
2253 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2254 of the protocol and it cannot be selected when encoding (maps into 'string'
2255 when decoding). Needed to talk to some servers.
2257 Demo client can request simple element set names.
2259 Added Diagnostic Format encoders/decoders.
2261 Added simple Close handling to frontend server (no hooks for resource
2262 reporting yet), and demonstration client.
2264 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2266 --- 1.0b3 1995/08/24
2268 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2269 handled incorrectly when records were requested in the searchResponse. This
2270 will only affect you if you use the frontend-server.
2272 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2273 Test-client will ask for and print GRS1. Ztest will return dummy records
2276 Added Explain encoders/decoders to the service-level API. Untested.
2278 Added Extended Services: Item Order encoders and decoders to the Service-
2279 level API. Untested. We could use a recent copy of the pertinent bits
2280 of the ILL protocol to add those bits.
2282 Added diagnostic format 1 encoders/decoders to the service-level API.
2285 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2286 odr_cons.c, which causes a more correct output.
2288 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2289 was always set to 0 when no records were requested in the searchRequest.
2291 * Added better external-handling. This shouldn't harm old code that
2292 *encodes* externals. It can break code that looks for a
2293 'single-ASN1-type' representation, since those types that are known
2294 are now decoded immediately. Look at the SUTRS sample code in
2295 seshigh.c and client.c. Documentation updated.
2297 Handling of structured records in bend_fetchresponse. Length -1 marks
2298 structured record, type is deduced from format field.
2300 --- 1.0b2 1995/06/27
2301 Fairly quick maintenance release to add SUTRS support.
2303 Fixed handling of SUTRS records in the demonstration client.
2305 * Added format field to the bend_fetchrequest and bend_fetchresponce
2306 structures of the backend API (frontend server). When the record is
2307 returned, the value of the format field is mapped to an OID. The
2308 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2309 of the record. The special value VAL_NONE in the bend_request means
2310 that no specific format was requested by the client. Documentation
2311 updated accordingly. Test server (ztest) will return a fixed dummy
2312 SUTRS record if your client requests SUTRS.
2314 Documentation updated accordingly.
2316 You can now set external libraries and RANLIB support in the top-level
2320 First public release.
