3 Fixed bug #2027: Crash when closing connection.
7 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
8 is built. Only this DLL depends on the ICU runtime.
10 yaz-ziffy is no longer part of YAZ. It is distributed separately by
11 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
13 Changed license of CCL module to 'Revised BSD'. After consultation with
14 remaining members of the original EUROPAGATE consortium, we are re-issuing
15 the CCL module without a separate license. The software was developed by
16 Index Data as part of a research project. The special license was included
17 to help feed usage information back to the project consortium to support
18 project evaluation. At this time, the project consortium has long-since
19 disbanded, and the majority of the original principals have retired. At the
20 same time, we have significantly modified the software during the following
21 years, to the point where very practically no original code remains. To
22 simplify re-use of the software, we have contacted those members of the
23 consortium who could be reached, and agreed to re-issue the module as a
24 proper part of the YAZ package.
26 Tcl scripts uses /usr/bin/tclsh as preferred shell.
28 CQL closer to being version 1.2 compliant. CQL also allows free-form
29 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
32 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
33 bug could make Extended services handling crash in the ZOOM layer. This
34 bug was only present in YAZ 3.0.18.
38 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
41 yaz-marcdump reads and writes collection wrapped records.
43 Handle OPAC for record conversion module.
45 Fixes for ICU wrapper.
47 Allow ICU libs to be controlled with --with-icu .
51 Added yaz_poll which is a wrapper for select/poll. When poll is available
52 and non-buggy, it is used, by yaz_poll . This allows more than 1024
55 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
56 functionality through an XML based configuration (ICU chain). This system
57 is useful for search facilities such as Pazpar2 and Zebra that needs to
58 perform tokenization of indexed material. The ICU code in a separate
59 library libyaz3_icu.a.
61 Added HTTP tunnel facility for COMSTACK, bug #1752.
62 This is a facility that allows a Web proxy, such as squid, to tunnel
63 Z39.50 traffic. This facility is "transparent" to must applications
64 using YAZ. It's enabled by using pseudo transport connect: followed by
65 the proxy address, followed by command, then follwed by he regular
66 "virtual" addresss. For example,
67 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
69 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
73 Fixed bad memory reference in ZOOM_record - cuased by member not being
74 initialized. This was a problem only in YAZ 3.0.12.
76 Fixed bug in conversion from MARC to XML: Non-XML characters in control
77 fields were not removed.
79 Changed the way C code is generated from codetables.xml. Made a MARC-8
80 conversion trie for each characterSet section rather than codeTable.
81 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
82 of codetables.xml from Larry Dixson, LOC. Bug #1464.
86 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
87 from ZOOM_record_error).
89 ZOOM C function ZOOM_record_get returns record schema for type="schema".
91 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
93 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
95 Better SRW-to-Bib-1 diagnostic mapping.
97 ZOOM C and yaz-client announces SRU version 1.2 by default.
99 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
102 Fixed in yaz_sru_decode to allow other version than 1.1.
104 --- 3.0.10 2007/08/22
106 Added support for SRU scan for ZOOM.
108 Added support for the use of the older versions or Extended Service
109 Update in ZOOM. To faciliate this, an option "updateVersion" may be
110 set to the version , 1=first, 2=second, 3=third. The third version is
111 what ZOOM C has used so far. And that, obviously, is the default.
113 Added support for CCL queries in Z39.50 queries sent to the GFS (and
114 therefore in Zebra and in SimpleServer-based applications). The new
115 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
116 qualifier file used to transform incoming CCL queries into Type-1 RPN,
117 which is passed into the back-end search callback function.
119 Added support for HTTP Basic authentication in clients: the SRU/W
120 codec encodes the username/password elements of the PDU structure
121 appropriately, and these may be set using the "user" and "password"
122 options in ZOOM-C applications (the same options that are used for
123 Z39.50 authentication).
127 Fixed bug #1208: SSL appears to be broken in ZOOM.
129 Fixed bug #1206: Libxml2 include path weirdness.
131 Added oid_name_to_dotstring.
133 Allow elementSetName to be specified for ZOOM C record update.
135 Allow waitAction to be specified for ZOOM C based for Extended Services.
137 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
138 syntax OID. Bug introduced in YAZ 3 series.
140 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
144 Fixed bug #1157: yaz-client does not read .yazclientrc from current
145 directory. yaz-client now reads commands from file given by option -f
146 if specified; then tries to read .yazclientrc in current directory.
147 Failing that, it reads .yazclientrc from user's home directory.
149 Added support for correlationInfo Note and ID for Record Update via
152 Added yaz-client command querycharset which specifies character set for
153 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
154 (termListAndStartPoint).
156 Charset ISO5428:1984 is an alias for ISO5428-1984.
158 Implemented a way to perform scan in a result set using Z39.50. This
159 is achieved by attaching the result set name in the characterInfo
160 (type InternationalString) of OtherInformation in the Scan Request PDU.
161 The result set is identified in the otherinformation by the new OID:
162 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
163 This allows for scan in result set and faceted search . Zebra did some
164 of this in the APT term using attribute type 8 and value being result
165 set. Using the OtherInformation approach for this is cleaner and easier
166 to work with in proxies and the like. This facility can be used in
167 yaz-client using new command setscan which takes a result set as first
168 argument, start position (APT) as second.
170 Changed decoding of SRU XML packed records to deal with servers that
171 have recordData with XML data with multiple root nodes. Also make
172 comparison for recordPacking case insensitive. Again, one server
173 returns "XML" where others return "xml".
175 For SRU responses allow Content-Type application/xml as well as text/xml.
179 Fixed bug in character set conversion of BER strings. Bug introduced
184 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
186 For OID class, use oid_class consistently.
188 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
191 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
192 character set for bibliographic information interchange". By Giannis Kosmas.
194 Added documentation on new OID API.
198 Changes to generic frontend server interface: added new member
199 'query_charset' for bend_initrequest structure. A backend init handler
200 should set this member to its native character set for query terms.
201 When defined, the frontend server logic will announce this character set
202 to a client if the negotiationModel bit is set by the client. All server
203 implementors are encouraged to specify this. If a backend server does not
204 specify this a warning is issued using yaz_log(YLOG_WARN,..).
206 Added CCL utility to remove terms (stop words) from resulting RPN
207 tree. This is handled by functions with prefix ccl_stop_words_ .
209 New ZOOM C option, "rpnCharset", which allows client-side conversion of
210 terms in RPN queries.
212 Clean-up the CCL API. Moved some internal structures from ccl.h to
213 private header cclp.h. Changed ccl_parser_create so that a Bibset must
214 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
215 This is replaced by ccl_parser_find_str which takes a string instead.
217 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
218 libyaz.la is the core of YAZ except the generic frontend server and
219 does not depend on POSIX threads anymore. libyaz_server.la is the
220 generic frontend server facilities and uses POSIX thread functionality
221 if available. The libyaz.la no longer depends on POSIX threads because
222 the number of global structures is limited. NMEM no longer re-uses blocks
223 between threads ; it simply free's memory immediately but allocates in
224 "large" chunks as usual. We don't expect any performance penalties
225 because of this. The yaz_log system is still using a global log_level so
226 caution must be taken when modifying it with yaz_log_init_.. +
227 yaz_log_mask_str. This, however, should not cause any trouble because
228 these functions are called during initialization of application code
229 anyway. `yaz-config --libs server` returns libs for server applications;
230 `yaz-config --libs` returns libs for non-server applications.
232 New OID database - with public definitions in oid_db.h. Removed old OID
233 database including the head oid.h and definitions such as enum oid_value
234 and struct oident. The new OID database uses the same string names as
235 before but the 'protocol' is gone. There are now only two representations
236 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
237 converts from string to OID; functions with prefix yaz_oid_to_string
238 converts the other way.
240 Change to emit_term() in CQL-to-PQF query translation: when a term has
241 the /regexp relation modifier, do not process it for leading and
242 trailing "^" and "*", which have quite different meanings in regular
245 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
246 write handlers no longer carries a 'last' parameter. This will make
247 yaz_iconv flush "less" characters. A flush is performed by call to
248 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
250 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
251 removed, because function yaz_query_to_wrbuf does the same.
253 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
254 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
256 Deprecated MARC utility functions removed.
258 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
261 Branch split: YAZ_2_1_55_branch
263 --- 2.1.54 2007/03/16
265 Fix to ZOOM-C so that transparent reconnection is properly handled on
266 connections that are in asynchronous mode.
268 Fixed compilation on OpenBSD 4.0.
270 Large strings in GRS-1 records are now properly displayed in yaz-client.
272 Added character conversion support for "advancegreek"; based on patch from
275 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
276 sequence is met. Before the error was not set so it would be unknown.
278 Adjust yaz-marcdump MARC reader so that it skips until record separator
281 --- 2.1.52 2007/03/07
283 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
284 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
285 fd_set structure used as a bitmask for the FDs to be selected on.
287 Using ACX_PTHREAD macro to check for POSIX threads.
289 Fixed have-vsnprintf check.
291 --- 2.1.50 2007/02/23
293 Fixes for configure on BSD. Bug #900.
295 Added snprintf/vsnprintf wrappers for systems that don't have
296 limits (heavens forbid).
298 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
299 created before all previous tasks were completed and removed from the
300 task queue, the new task could be removed by a mistake.
302 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
304 Implemented pass-through CQL-to-PQF conversions. Bug #861.
306 Fixed bug #832: Problem with MARC/charset in yaz-client.
308 Fixed bug #668: save command line history for yaz-client.
310 Fixed bug #830: pkg-config support.
312 --- 2.1.48 2007/01/23
314 Extended ZOOM result set options with two options that may be read by
315 a client: resultSetStatus and presentStatus with values as specified for
317 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
319 Fixed bug #827: Using SSL fails on Debian etch.
321 Fixed bug #826: Weird looking chars for set of MARC records.
323 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
324 that is treated as an ItemOrder with itemRequest being an XML document
325 external. The value of "doc" is the content.
327 Extended the GFS search facility. New member of bend_search_rr
328 'estimated_hit_count' signals that hits is known to be an estmate
329 (higher or lower than real hit count). New member 'partial_resultset'
330 signals that the search was partial (hit count is lower or equal than
331 real hit count). For Z39.50, the information is stored in resultSetStatus
332 member of SearchResponse APDU. For SRU, the information is signalled
333 via SRU diagnostic 59: "Result set created with valid partial results
336 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
338 --- 2.1.46 2007/01/13
340 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
342 Added ZOOM_connection_peek_event.
344 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
345 the following new functions:
346 ZOOM_event_nonblock, ZOOM_connection_process,
347 ZOOM_connection_get_{socket,mask,timeout},
348 ZOOM_connection_fire_event_{timeout,socket}.
349 The existing blocking event handler, ZOOM_event, is a wrapper for the
350 + blocking ZOOM_event_sys_{poll,select}.
352 Implemented function ccl_xml_config which parses XML version of CCL
353 configuration (bug #798).
355 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
357 Added timings utility (yaz/timing.h)
359 --- 2.1.44 2007/01/03
361 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
364 Fixed bug #779: Rotation of apdu.log fails.
366 Fixed for character set conversions:
367 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
368 Honor G1 set in MARC-8 decoding.
370 --- 2.1.42 2006/12/17
372 Fixed bug #775: char conversion does not handle Alternative UTF-8
375 Implemented function yaz_marc_read_line which parses MARC line format
376 records. There is a wealth of formats out there. So far, this function
377 reads line records produced by yaz_marc_write_line.
379 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
380 more generic and easier to remember(!) options: -i format and -o format
381 which specifies input format and output format respectively - where
382 format is one of "marc", "marcxml", "line", "marcxchange".
384 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
385 does not print anything except warnings for records.
387 For yaz-marcdump, added support for MARC split into files (-s) with a given
390 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
391 spec, at http://www.loc.gov/standards/sru/record-update/
392 This has changed the binary layout of the following structs:
393 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
394 bend_update_rr . Patch by Ko van der Sloot.
396 Added GFS utility function bend_assoc_is_alive which returns 1 if
397 association is still alive (client is connected); 0 otherwise (client
398 closed connection). This allows busy servers to stop working for
401 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
402 been a separate piece of software. This version of ziffy has been modified
403 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
405 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
407 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
408 Client code may now interrogate options such as "init_opt_sort" to
409 find out whether the server claims to support various options.
411 --- 2.1.40 2006/11/27
413 Added utilities yaz_{set,get}_esn to set/get element set name from
416 Removed the build of libyazthread.la. The libyaz.so is the threaded version
417 of YAZ and has been so since YAZ 2.1.10.
419 Implemented ZOOM_record_error which returns error information for
420 record (surrogate diagnostic).
422 --- 2.1.38 2006/10/31
424 Updates for SRU Update by Ko van der Sloot:
425 1. Changed name from "operation" to "action"
426 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
427 versions in the code, marked as 'backward compatible'.
428 3. Added diagnostics for SRU Update.
430 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
432 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
434 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
436 For GFS, fixed problem with SRU diagnostic 'First record position out of
437 range' being issued for 0 hits.
439 zoomtst10 part of Windows Build.
441 --- 2.1.36 2006/10/13
443 Implemented yaz_filepath_comp which splits a path into file path
444 components (required by Zebra 2.0.3+).
446 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
447 BSD inspired license until now so this should not have any real impact on
448 anybody. See http://www.opensource.org/licenses/bsd-license.php
450 Fixed bug #687: Missing log lines.
452 Fixed bug #678: CQL to PQF translation does not preserve double-quote
455 Fixed bug #689: SRU diagnostics to be added.
457 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
458 whether a connection is idle (no more work do do).
460 --- 2.1.34 2006/10/04
462 Change type of optval from long to int for invocation of setsockopt with
463 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
465 Added support for specifying the max log file size for the Generic
466 Frontend Server. The size is given with option -r.
468 --- 2.1.32 2006/09/21
470 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
472 --- 2.1.30 2006/09/17
474 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
477 Fixed bug in Generic Frontend Server that could cause a server to stop
478 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
480 For the generic frontend server, the maximum record size is used as maximum
481 size of incoming packages (SRU + Z39.50). The value until was previously
482 only used in Z39.50 Init negotiation and, later, in a session controlled
483 sizes of records returned. This is controlled using -k option. It can be
484 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
486 --- 2.1.28 2006/09/04
488 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
491 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
493 New option for yaz-marcdump -lpos=value which allows setting a portion
494 of MARC header to a certain value.
496 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
498 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
499 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
501 --- 2.1.26 2006/08/15
503 Fixed problem with SRU mode type (soap, get, post) for yaz-client
506 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
508 --- 2.1.24 2006/08/08
510 Fixed MARC ISO2709 encoding routines to deal with character set
513 Minor changes to GFS logging. Database included in search request log
516 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
517 cached/multiple records.
519 Shared libraries are built by default on Unix+configure.
521 Changed cql2pqf transformation to use a different evaluation order. The
522 new order is: always, relation, structure, position, truncation, index
523 and relationModifier. Old order was: always, relation, relationModifier,
524 structure, index, position, truncation. Note that the the latter ones
525 override former ones for identical attributes.. The new scheme means that
526 it is possible to override any existing attribute with a relationModifier.
527 And also that it is possible to override everything for the index rule
528 (except the ones listed in relationModifier). No order is perfect but this
529 one, we believe, covers more real cases.. The "always" should have been
530 called "default", since the attributes there can be overridden with all
533 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
534 compilation phase, but also for yaz-config --cflags output. This allows
535 us to have public headers with Libxml2 stuff in them . It should also,
536 eventually, make Libxml2 checks redundant in packages using YAZ, such
539 --- 2.1.22 2006/06/15
541 Changed SRU update structure bend_update_rr so that SRU diagnostics are
542 stored in uri, message and details.. Previously diagnostics were stored
543 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
544 compatibility.. but he's probably the only one affected, so.
546 Added support for CCL, compiled on the client side, in ZOOM-C. This
547 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
548 input; the resulting query objects can be used for for searching with
549 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
551 YAZ' configure searches for OpenSSL by default.
553 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
554 SL_CTX_use_certificate_file. See
555 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
556 for more info. Thanks to Ko van der Sloot.
558 --- 2.1.20 2006/06/02
560 Bug #600: SRU GET, POST support for yaz-client. Introduced
561 command 'sru' which selects method SOAP/GET/POST.
563 Allow missingValueAction to be specified for the sortspec string -
564 function yaz_sort_spec. By default, the missing value action is null.
565 Use ! to specify "abort". Use = followed by stringvalue to specify default
568 Ensured that Present-handler (if defined) is called in GFS before any call to
569 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
570 searchRetrieve requests.
572 Documentation for YAZ is now based on the Docbook XML/XSLT using
573 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
574 is no longer depending on jade/openjade or docbook-to-man scripts.
575 PDF is no longer part of the distribution - but can optionally be
576 made using DSSSL/jadetex or FOP.
578 Added retrieval handling support in Generic Frontend Server to support
579 conversion between MARC/XML as well as XSLTtransforms. See
580 etc/yazgfs.xml for an example.
582 Added Authentication support to Generic Frontend Server in SRU
583 mode. Authentication using HTTP Basic is supported, as is the use
584 of 'x-username' and 'x-password' parameters in the request itself.
586 Added support for a new character set MARC8s identical to MARC8 except
587 that it converts combined characters to single Unicode characters in the
588 Latin-1 range (when possible).
590 --- 2.1.18 2006/04/24
592 ASN.1 compiler 0.4: generates brief Doxygen file header for
593 generated .h/.c files.
595 Utility yaz_iconv now supports conversion to MARC-8.
597 New facilities for the MARC module. The reading - and writing of
598 content are separate methods for the yaz_marc_t handle. The following
599 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
600 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
601 format). Write functions have prefix yaz_marc_write_.. The existing
602 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
603 available. Removed support for OAI-MARC and simplexml (not the
604 simplexml from PHP5).
606 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
607 to be returned for this connection.
609 --- 2.1.16 2006/03/31
611 Allow multiple languages and charsets to be specified with
612 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
613 negcharset iso-8859-1,utf-8
615 Translation of proximity nodes from CQL into PQF now works.
617 Moved to automake 1.8, 1.9.
619 Added function yaz_log_set_handler which allows a log handler to be
620 installed. This handler will be called for all log messages. Output
621 to file is also produced; but that can be disabled by passing NULL
622 fname to yaz_log_init_file.
624 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
626 For SRW (including GFS), accept application/soap+xml as content-type
629 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
630 produces NO stylesheet reference even if a default stylesheet is specified
633 --- 2.1.14 2006/03/14
635 Updated Windows package to include yazd.dll + yazd.lib for the
636 Development component.
638 If the environment variable YAZ_LOG is set, then it is used as a
639 string indicating the default level of logging to use if not
640 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
641 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
642 used as before. So, for example, to omit warnings from YAZ logging,
645 cql_transform() now map structure and other attributes before indexes,
646 so that index-specific structures and other attributes can override
647 defaults. So now a combination of mapping specifications such as:
649 index.dc.date = 1=date-modified 4=5
650 does the right thing.
652 cql_transform() now also respects the "always" mapping specification,
653 which establishes an initial set of attributes to be used for all
654 terms except where overridden by more specific attributes associated
655 with the index, relation or modifier.
657 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
658 which mode to use; one of "post", "get" or "soap" (SRW, default).
660 Fixes for yaz_iconv routines: changed trie-based character set conversions
661 to use only non-negative values for bit fields due to Sun's C compiler not
662 supporting negative values.
664 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
665 sequences where not read correctly. Fix by Rustam Usmanov.
667 Updated win/makefile to use options, settings which makes things
668 compile with VS C 2005.
670 --- 2.1.12 2006/02/01
672 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
674 In ZOOM socket code, use select instead of poll on MacOSX.
676 ZOOM-C now support client-side compilation of CQL into RPN that is
677 sent to the server, enabling CQL to be used against all Z39.50
678 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
679 ZOOM_query object, and submit it using ZOOM_connection_search().
680 The CQL-to-RPN translation uses a configuration file, the name of
681 which must be specified in the Connection's "cqlfile" option.
683 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
684 function, which takes as its start-term parameter a ZOOM_query object
685 (which may have had either CQL or RPN set into it).
688 --- 2.1.10 2005/11/29
690 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
691 GFS to support this as well. Backend handler, bend_srw_update, does the
692 update work. Code contributed by Ko van der Sloot.
694 Allow retrieval of Search Result-1 information in ZOOM by the use of
695 options that are attached to a result set. ZOOM documentation updated
698 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
699 UTF-8 conversion. Patch by Raj Patel.
701 Added option -m to GFS to control formatting of timestamps in log file.
703 Added 'exit' as synonym for 'quit' in yaz-client
705 Added support for specifying SRW resultSetId + resultSetIdleTime in a
706 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
707 for the new members. Patch by Ko van der Sloot.
709 Added support for SRU POST. It is supported for content-type
710 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
712 Do not build the separate Multi-threaded (MT) library libyazthread.la.
713 Instead make the library libyaz.la multi-threaded. Threading as a whole
714 can still be disabled by configure option --disable-threads. Previosly,
715 with older GLIBCs there were problems with MT libs under Apache. This
716 has now been fixed a long time ago.
718 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
721 CQL module modified to be case insensitive for relations/indexes/operations.
723 Fixed bug in CQL transform code: incorrect value relationModifieder
726 Added 'show all' command for yaz-client which retrieves all results
729 Added new yaz-client, xmles, which takes a (private) OID and
730 a document to be sent as an extended service request.
732 Describe new yaz-client commands wait_response and set_auto_wait.
734 Increase TCP/IP listener backlog from 3 (which I am guessing was
735 copied from the SunOS manual entry way back when) so SOMAXCONN, so
736 that the socket will queue as many incoming connections as it's able
737 to handle ongoing connections. In other words, it will never now
738 refuse a connection that it would be able to handle merely because
739 it's not got around to accepting() enough of the pending connections
740 yet. This is the behaviour anyway under Linux, where the listen()
741 argument is ignored; but not under BSD and on systems such as
742 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
743 YAZ-based servers should now be uniform across operating systems in
746 yaz-marcdump uses 64-bit file access on some systems. This is enabled
747 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
748 This allows yaz-marcdump to read large MARC batches (>2 GB).
750 Modified all YAZ source files - except the source which is auto-generated
751 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
754 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
755 corresponding to the existing *_setl() function. These allow option
756 values containing arbitrary valuues.
758 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
759 ZOOM_resultset_sort() in new applications. Its behaviour is identical
760 except that it returns an indicator of whether or not the sort
761 criterion was accepted (0 for OK, -1 for invalid).
765 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
766 MARC output rather than returning "new" buffer.
768 yaz-client warns about unknown init options.
770 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
774 Added support for SRW sort in Generic Frontend Server. Patch
775 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
776 sortKeys - or NULL if none is provided.
778 Fixed bug #307: It was impossible to specify indefinite/no timeout
779 for ZOOM_event. Special timeout value -1 now means indefinite timeout
782 Added support for multiple languages and charsets to be specified in
783 ZOOM. Each charset/language is separated by a blank. If negotiation is
784 in effect in init-response, Option
785 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
786 Code based on patch by Vasiliy Osadchuk.
788 Fixed bug #306: infinite recursion that occurred when calling
789 yaz_log_level_init as the first call (before other log level or
792 Fixed bug in scan handling in front end server: if preferred-Position-In-
793 Response was non-present, a NULL pointer referece was performed.
797 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
798 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
799 now defined for all those error codes. So instead of putting 109 in
800 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
801 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
803 Modified the yaz-marcdump utility to skip garbage bytes between MARC
806 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
808 Program yaz-client now exits and produces an error message if multiple
809 Z39.50 servers are specified on the command line (none or one allowed
812 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
817 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
819 Fixed bug #272: Preserve spacing for CCL terms.
823 Added support for virtual hosts and multiple backend servers for
824 the YAZ frontend server. The configution is XML based and
825 support specificition of CQL to RPN mappings and explain information.
826 See section "Virtual Hosts" in the YAZ manual.
828 Extended OPAC display utility. OPAC display utility renders
829 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
830 to supplement yaz_marc_decode_wrbuf.
832 Fixed a bug in MARC decoder that could caused it to crash for some
833 invalid MARC records. More diagnostics and warnings where added in
834 XML output (warnings, etc are stored in comments).
836 --- 2.0.34 2005/02/08
838 Fixes for UNIX domain sockets. Bug #261.
840 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
842 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
843 Added yaz_marc_subfield_str which defines subfield lead string which is
844 used in YAZ_MARC_LINE format. Default string is blank+$. Added
845 yaz_marc_endline_str which defines end of fields string used in
846 YAZ_MARC_LINE format. Default string is newline.
848 Experimental support for MarcXChange. This format can be produced
849 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
850 http://www.bs.dk/standards/MarcXchange.xsd
852 Added yaz-client commands scansize that sets maximum number of
853 entries to be returned by scan.
855 --- 2.0.32 2005/01/11
857 Added support for SRW scan in yaz-client and Generic Frontend Server.
859 * Added whereInList member to SRW Scan Term.
861 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
863 Fixed NMEM system to return aligned blocks on the smallest boundaries
864 that are suitably aligned for all possible types on the particular
865 architecture YAZ is being built for.
867 --- 2.0.30 2005/01/04
869 Fixed numerious warnings that was issued with newer versions of GCC.
871 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
872 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
875 Make YAZ Generic Frontend Server slightly faster.
877 Enhance (and reduce) logging for Generic Frontend Server.
879 Revert YAZ log system so that it flushes every write operation
880 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
882 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
883 instead of LOG_, due to name clash with syslog(3). LOG_ are still
884 present. New applications should define YAZ_USE_NEW_LOG=1 - this
885 will effectively disable old definitions.
887 --- 2.0.28 2004/11/09
889 Added yaz_log_time_format which specifies log format using
892 Added yaz_log_module_level which returns mask for a module. Value
893 is non-zero mask a if module is enabled; zero if disabled.
895 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
896 in include/yaz/cql.h.
898 Fixed bug #176: Dont throw diagnostics on empty SRU args.
900 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
902 Fixed bug #172: RPM builds does not enable SSL.
904 Doxyfile.in part of dist. Doxyfile generated by configure.
906 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
907 are given and the corresponding component does not exist.
909 Extend CCL documentation in YAZ reference. Describe r=r.
911 --- 2.0.26 2004/10/01
913 Fixed MARC->MARCXML conversion to properly deal with
914 fields, subfields, indicators having non-ASCII characters.
916 Fixed MARC->MARCXML conversion so that ASCII control characters
917 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
920 Added YAZ GFS support for conversion from Z39.50 surrogate
921 diagnostics to SRW surrogate diagnostics.
923 Bug fix: YAZ GFS did not return schema in explainResponse.
925 --- 2.0.25 2004/09/30
927 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
928 now converts recordSchema to elementSetName as well as schema URI.
930 Fixed bug in COMSTACK that prevented HTTP request packages from being
933 --- 2.0.24 2004/09/29
935 Added CCL facility r=r "range" which is similar to r=o "ordered" but
936 does not require white-space before and after the dash in a range, e.g.
937 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
940 Fixed a few AC_TRY_LINK configure tests that did not operate properly
941 due to new GCC removing "redundant" code.
943 Added yaz-client commands scanpos and scanstep that sets preferred
944 position and step-size for scan.
946 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
948 Added CCL utility ccl_qual_buf which parses one or more CCL
949 spec lines in a buffer.
951 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
952 of name and value - ignoring empty lines and comments.
954 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
956 Added odr_get_element_path which returns current element path for an
957 ODR handle. This utility is useful in error handling or user-defined
960 Added ODR_PRINT utility odr_set_stream which is is a more generic
961 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
962 to a write function and pointer to close function. The close function - if
963 non-NULL - will be called during odr_destroy.
965 Fixed bug in CCL parser where truncation char was not removed from
966 right side when truncation=both was in effect.
968 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
971 --- 2.0.23 2004/08/11
973 Fix buffer overrun in CQL parser when dealing with proximity (%).
975 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
976 to UTF-8/UCS conversion is now only based on codetables.xml.
978 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
980 --- 2.0.22 2004/08/06
982 Add support for more "commit changes" in ZOOM (uses Extended Services).
984 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
987 Yet another small fix for configure of SSL.
989 --- 2.0.21 2004/05/14
991 Fix SSL libs for configure when --with-openssl=DIR is given.
993 --- 2.0.20 2004/05/10
995 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
997 SSL comstack now uses yaz.pem certificate file on server side
998 by default. Certificate filename can be configured by calling
999 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1001 Fix bug regarding multiple calls to ZOOM_connection_connect.
1003 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1005 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1006 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1008 ZOOM now allows inspection of X509 peer certificate for verification.
1009 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1011 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1012 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1013 as "modular" but it simplifies things.
1015 Added cs_get_peer_certificate to that returns peer X509 PEM.
1017 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1018 NULL if SSL is unavailable.
1020 Documentation about MARC decoding tools.
1022 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1024 --- 2.0.19 2004/03/30
1026 Rename CHANGELOG to NEWS to follow GNU style packing.
1028 Fix bug with missing initialization of member in init_diagnostics.
1029 This bug affects threaded version of GFS server.
1031 --- 2.0.18 2004/03/20
1033 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1036 Ensure zlib.dll is packed with Windows install.
1038 --- 2.0.17 2004/03/17
1040 Fix encoding of xsd:string to use text instead of CDATA.
1042 Fix endless loop in CQL parser with unbalanced ".
1044 Use a more compact way to store MARC-8 conversion tables.
1046 --- 2.0.16 2004/03/16 Debian only
1048 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1051 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1056 --- 2.0.15 2004/03/01
1058 Another fix for decoding of XML packed records.
1060 --- 2.0.14 2004/02/25
1062 Fixes for Chunked encoding. White space not ignored after length spec.
1064 Update NS and use default NS for SRW diagnostic elements.
1066 --- 2.0.13 2004/02/23
1068 Implement ZOOM_resultset_cache_reset which resets record cache.
1070 Implement ZOOM_resultset_sort which sorts a result set.
1072 Implement chunked HTTP transfer.
1074 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1076 --- 2.0.12 2004/02/16
1078 Added member 'schema' to bend_explain_rr structure so that backend
1079 can specify explain record identifier. Defaults to Zeerex 2.0.
1081 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1083 --- 2.0.11 2004/02/16
1085 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1088 Added init command for yaz-client which sends "extra" init request.
1090 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1091 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1093 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1095 Make ZOOM error code for "invalid query".
1097 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1099 --- 2.0.10 2004/02/05
1101 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1104 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1106 Added option -p <file> to make Generic Frontend Server to write PID file.
1108 Added option -D to put Generic Frontend Server in background on its own.
1110 Make ZOOM C recognize option "password". If unset, "pass" is used
1111 (for backwards compatibility).
1113 Fixed a bug in Generic Frontend Server that could make it crash if a
1114 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1117 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1118 Must be issued before open, in order to be in effect.
1120 --- 2.0.9-6 2004/01/12 Debian/Windows
1122 Make the SRU server more picky WRT unknown params, etc.
1124 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1126 New YAZ client command, options, that sets Z39.50 options.
1128 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1129 options from a string of tokens (one token for each option bit).
1131 Update SRW diagnostic code messages.
1133 --- 2.0.9-5 2004/01/07 Debian/Windows
1135 Handle user defined stylesheet for SRW/SRU.
1137 --- 2.0.9-4 2004/01/06 Debian/Windows
1139 Fix bug in decoding of Content-Length.
1141 --- 2.0.9-3 2004/01/06 Debian/Windows
1143 Fix a bug with decoding of XML packed records.
1145 --- 2.0.9-2 2004/01/05 Debian only
1147 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1149 Fix bug in SRW/SRU diagnostics decoding.
1151 --- 2.0.9 2004/01/05
1153 Fixed bug in Generic Frontend Server which could drop records exceeding
1154 preferred message size. Reported and fixed by Irina Dijour.
1156 Fixed calculation of package size for structured records in Generic
1157 Frontend Server. Reported and fixed by Irina Dijour.
1159 Fixed namespace for SRW/SRU diagnostics.
1161 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1163 --- 2.0.8 2003/12/22
1165 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1166 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1169 CQL changes to reflect recent changes to the specification:
1170 * Documentation talks about context sets instead of index sets.
1171 * Documentation talks about indexes instead of qualifiers.
1172 * The CQL-to-PQF transformer's configuration file now uses
1173 "index.set.name = <attributes>" instead of the old form
1174 "qualifier.set.name = <attributes>". (Both forms are still
1175 understood but the latter is deprecated.)
1176 * CQL terms with no explicit index specified are now interpreted as
1177 cql.serverChoice instead of srw.serverChoice (which of course
1178 behaves exactly the same.)
1180 --- 2.0.7 2003/12/16
1182 MARC conversion can now generate ISO2709 output in another
1183 character set. yaz-marcdump uses this facility if you invoke it
1186 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1187 functions from there can be used from C++.
1189 --- 2.0.6 2003/12/04
1191 Frontend server now transfers memory from decoded packages to stream
1194 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1195 references to show up.
1197 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1198 the ZOOM Abstract API. The older names for the same options are still
1199 also supported for the benefit of old applications.
1201 ZOOM-C supports "implementationId" and "implementationVersion" options
1202 to go along with "implementationName". These allow the user code to
1203 specify identification strings to be sent to servers.
1204 Add OID for the new ExtLite attribute set.
1206 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1207 as requested/supplid by Ere Maijala <ere@atp.fi>
1209 For generic frontend server, reverse the order of
1210 "toolkit-supplied / application-supplied" strings sent as implementationId,
1211 Name and Version. Also, remove the spaces around the slash. This brings
1212 the GFS in line with the behaviour of ZOOM-C on the client side.
1214 Add function ZOOM_scanset_display_term.
1216 yaz-client shows scan displayTerm if present.
1218 Utility yaz-iconv is now installed by default along with the man page
1221 Extend configure check for OpenSSL to use pkg-config where available (such
1224 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1225 server to specify uid/gid/mask for socket using the format
1226 unix:[user=uid,][group=gid,][umask=mask,]file=path
1227 If file= is omitted the existing format is assumed, e.g.
1229 in which case the mask is 0666 (rw for everybody).
1231 Major restructure of YAZ source. All source in libyaz is in src directory.
1232 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1233 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1235 Added man page for utility yaz-marcdump (used to be called marcdump).
1236 yaz-marcdump is installed by 'make install'.
1238 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1239 of incoming package failed.
1241 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1243 Change prototype of odr_perror: add const to message string.
1245 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1247 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1248 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1249 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1250 DNS lookup. There should not be any compatibility problems with this
1251 assuming that blocking=1 or 0 is used.
1253 Fix bad reference in UNIX comstack in function cs_addrstr.
1255 Fix for compilation on AIX.
1257 The generic front-end server (server/seshigh.c) now supports returning
1258 Init diagnostics to the client in User-information-field, in
1259 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1262 --- 2.0.4 2003/09/04
1264 Allow any CQL relation (not just all,any,exact,scr).
1266 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1267 that features the same UI.
1269 Implemented command update0 in YAZ client which is equivalent to
1270 update but uses old of Ext Update ASN.1.
1272 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1273 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1274 Previously no OID was used for this info.
1276 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1277 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1278 returns 'malformed search term' otherwise.
1280 SortResponse member resultCount now set to NULL in sort handler of
1283 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1286 Add three new utility functions for translating OIDs between various
1287 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1288 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1289 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1290 char *oid_to_dotstring(const int *oid, char *oidbuf);
1291 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1293 Reverted modifications for ES Update definition for z_IU0Update
1294 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1295 is back to YAZ 2.0.2.
1297 String value attributes for CCL parser.
1299 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1300 which their FirstSearch server returns in Init responses, sometimes
1301 carrying useful diagnostic information when Init fails. This has the
1302 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1303 "z39.50/oclcui.asn", where its definition is somewhat different from
1304 what OCLC document on their web-site, as required to interoperate with
1307 Support for anonymous authentication in yaz-client. Use the command
1310 * Fix the OID of the Index Data-local "admin" Extended Service from
1311 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1312 the 1000, which indicates a locally-defined OID, was a mistake.
1314 --- 2.0.3 2003/06/20
1316 Fix CCL directive @case handling so that it affects string match for
1317 both CCL keywords and qualifiers.
1319 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1320 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1321 Decoder has been updated with ASN.1 changes as listed in
1322 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1323 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1324 z_IUUpdate, remains unchanged.
1326 ZOOM_record_get may now return a record in a specific character set.
1327 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1328 "from" is the character set of record as returned by target. "to" is
1329 the character set to be returned. If omitted, "to" is UTF-8.
1331 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1333 New ODR utility, odr_getelement, which returns name of element for
1334 which encoding/decoding failed.
1336 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1337 in cases where a required element was omitted.
1339 Bug fix: some MARC8 sequences were not converted.
1341 New ZOOM option "step" which specifies number of records to be
1342 retrieved in one chunk. Used in conjunction with "start" and "count".
1344 SRW support for yaz-client. Use scheme http: to use it, e.g.
1347 yaz-client no longer does (un)intelligent character set conversions
1348 by default. Can be enabled with charset and marc_charset commands.
1350 xmalloc trace fix for 64-bit systems such as DEC alpha.
1352 Solaris 2.6 compile fix.
1354 New function, cql_strerror() translates SRW error codes, as returned
1355 by cql_transform_error(), into human-readable English strings. Used
1356 in yaz-client diagnostics when appropriate.
1358 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1359 converts it into a type-1 query which is sent to the server. This
1360 makes CQL available for use with all Z-servers, as opposed to the tiny
1361 minority that can handle CQL queries themselves.
1363 --- 2.0.2 2003/04/28
1365 New Debian package layout similar to the Redhat Package layout.
1367 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1368 and search result respectively.
1370 --- 2.0.1 2003/04/25
1372 Redhat package is now several packages: libyaz (runtime libraries),
1373 libyaz-devel (development and documentation, and yaz (utility programs).
1374 Package spec file by Morten Bøgeskov.
1376 New member 'schema' in struct bend_fetch_rr which the name of requested
1377 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1378 handler MAY set this to reflect the schema of the returned record.
1380 New member 'display_term' in struct scan_entry. GFS now sets member entries
1381 and allocates scan entries to be filled by user scan handler. In previous
1382 version, entries member was allocated by the scan handler. That still works,
1383 but the GFS will ignore member display_term - assuming it was NOT set by
1384 the handler. The fact that the GFS now allocates the entries both allows
1385 for new members and makes a scan handler easier to write.
1387 Fix CQL lex buffer overflow.
1389 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1390 SRU default recordPacking is string.
1392 SRU protocol support for frontend server.
1394 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1396 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1398 Added scan for the ZOOM shell (zoomsh).
1402 * String Identifers for Schemas (Amendment 5).
1403 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1404 Old definition for schema
1405 Odr_oid *schema; /* OPT */
1410 Z_InternationalString *uri;
1411 #define Z_Schema_oid 1
1412 #define Z_Schema_uri 2
1415 * resultCount parameter to Sort Response (Amendment 1).
1416 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1418 Support for SRW 1.0 over HTTP. This is an optional feature and
1419 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1422 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1423 on the same port. SRW SearchRetrieveRequests are mapped
1424 to bend_init,bend_search,bend_fetch,bend_close.
1426 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1428 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1429 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1431 ZOOM connections are SRW based if schem http is used for hostname
1432 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1433 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1435 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1436 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1437 distance=n, order=true/false, relation=le, prox unit=word. If
1438 n is omitted, distance 1 is used.
1440 Fixed problem with C compiler include path in wrong order.
1442 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1443 on Solaris. Patch from Ko van der Sloot.
1445 New MARC decode API. All new functions operate on a yaz_marc_t
1446 handle. The most important new functions are: yaz_marc_create,
1447 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1448 decode and destroy respectively. Decoder can produce formats
1449 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1450 include/yaz/marcdisp.h.
1452 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1453 to UTF-8, UCS-32, wchar_t or Latin-1.
1455 * Prototypes for yaz_iconv_-functions moved to separate header
1456 include/yaz/yaz-iconv.h.
1458 Make a few private functions 'static' in unix.c. This prevents
1459 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1461 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1462 are set when Init Response is received.
1464 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1465 but returns diagnostic set as well.
1467 New function yaz_strerror which is a portable wrapper for
1468 strerror/strerror_r/GetLastMessage.
1470 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1471 is returned for MARC. If type is "oai", then OAI MARC is returned.
1473 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1476 --- 1.9.2 2002/11/26
1478 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1480 Fix bad race conditions on SIGTERM and terminate gracefully in
1483 Move retrieval (data1) module to Zebra since nobody seems to be
1486 Add GRS-1 render for ZOOM using same format as yaz-client.
1488 --- 1.9.1 2002/10/05
1490 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1492 Fix broken ESpec handling in data1 module.
1494 SGML reader parses comments and makes them part of the data1 tree.
1496 Added several type casts so that YAZ compiles as C++ code.
1498 ZOOM didn't handle PDU encoding failures properly.
1500 Added more Bib-1 diagnostics (approved extensions).
1502 GNU configure: better check for iconv.
1504 More portable use of accept, getpeername. Check for socklen_t. Use
1505 int/size_t if socklen_t is not defined.
1509 PQF parser rejects bad queries - including those with extra
1510 characters in them. PQF parser used to silently ignore that.
1511 Cleaner API for PQF added, which allows you to get detailed
1512 error information for bad queries (see yaz/pquery.h).
1514 Fixed bug in ZOOM_record_get for type "database".
1516 Implemented mini iconv library supporting conversions between
1517 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1519 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1521 --- 1.8.9 2002/08/20
1523 Fixed ZOOM C record cache so that preferredRecordSyntax and
1524 elementSetName is used to check for already fetched records.
1526 --- 1.8.8 2002/08/02
1528 Added three members in bend_initrequest structure to facilitate
1529 character set negotiation.
1531 Fixed a bug in frontend server that could cause indefinite
1532 loops under rare conditions.
1534 Revised character set utilities (charneg.h) so that encoding
1535 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1537 For PQF, directive @term <type> sets term type for Scan/Search.
1538 Here <type> is general, string, numeric, null. The term type
1539 is inherited - just like @attr.
1541 New call odr_set_charset that sets character set conversion for
1542 international-strings on a ODR stream. Prototype is:
1543 int odr_set_charset(ODR o, const char *to, const char *from);
1544 The InternationalString is still represented as C string in YAZ
1545 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1546 won't). On the protocol level, you can use any encoding.
1548 Support for UNIX sockets in ZOOM.
1550 Solaris recv sometimes returns errno == ENOENT. It is treated as
1551 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1553 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1554 both client and server. Code by Morten Bøgeskov.
1556 --- 1.8.7 2002/05/22
1558 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1559 that they can be used directly from Visual Basic. You must recompile
1560 your windows APP if you're using ZOOM.
1562 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1563 Commands "lang" and "charset" sets language and character set respectively.
1564 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1565 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1567 Attributes from multiple CCL fields may be OR'ed rather than merged
1568 using directive "@field or". Fields are still merged by default -
1569 equivalent to "@field merge".
1571 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1574 Fixed bug in zget for parameter ExtendedServicesResponse.
1578 --- 1.8.6 2002/03/25
1580 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1582 Client displays USR.1:SearchResult-1 (hits per term).
1584 Additional Search Info for search in Generic Frontend Server.
1586 Fixed CCL parsing of "field=s".
1588 WIN32 installer - using the excellent NSIS software from nullsoft.
1590 Fixed CCL parsing of "field = - <number>".
1592 Added function yaz_marc_decode that decodes MARC for line mode
1593 display or XML (similar to that used by JZKit).
1595 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1596 Z39.50. But ISO/ILL was, however.
1598 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1599 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1601 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1602 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1604 --- 1.8.5 2002/02/03
1606 New YAZ client features: Command completion and new commands:
1607 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1608 Code provided by Jacob Poulsen.
1610 New call oid_trav, that visits all registered OIDs via callback.
1612 Function ZOOM_record_get now returns const char pointer rather than
1613 void pointer. It saves a lot of type casts.
1615 For YAZ client, command "auth" now allows you to set authentication
1616 in IdPass style. It is enabled when three tokens are given - order
1617 is user, group and password.
1619 Fix memory leaks in MARC record handling for ZOOM.
1621 New option for YAZ client, -k <kilobytes> that sets
1622 maximum record size. Similar to -k option for generic frontend
1623 server and yaz-ztest.
1625 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1627 Prefix query parser reports "fail" when bad attribute set is given.
1629 Fix in MARC decoder. Proximity logging. Fix for attribute set
1630 in scan handler for server. Patches by Shigeru Ishida.
1632 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1635 Configure option --with-openssl=<dir> now works when a directory is
1636 specified. Patch provided by Morten Bøgeskov.
1638 New option for YAZ client, -u <auth>, that sets authentication.
1640 ZOOM fix: error information was sometimes "missing", since error
1641 was cleared/reset too when it shouldn't.
1643 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1645 --- 1.8.4 2002/01/04
1647 Scan for ZOOM API. New object ZOOM_scanset. New functions
1648 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1649 ZOOM_scanset_destroy.
1651 New ZOOM function, ZOOM_connection_last_event, that returns type
1652 of last event (such as "receive data", "send data", "apdu received",
1655 New ZOOM option, schema, that specifies schema for retrieval.
1657 New CCL feature. Qualifiers can be aliases for one or more
1658 other qualifiers (if more than one is given, OR is used).
1660 ZOOM uses named result sets if target supports it.
1662 Two new YAZ client commands: . (dot, which sources a script of YAZ
1663 client commands), and ! (to execute shell command.). Implemented
1666 Working on Debian packages.
1668 --- 1.8.3 2001/11/19
1670 YAZ client enables named result sets only if target supports it.
1672 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1674 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1675 with key="host" to get same result.
1677 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1678 Function Z3950_resultset_record(s) returns references to records
1679 "owned" by resultset. To become owner use Z3950_record_clone.
1681 Function z_ext_record handles Extended Services. Thanks to
1684 --- 1.8.2 2001/11/12
1686 CCL Parser fix: ignore token comma when dealing with and-lists.
1688 Documentation updates for COMSTACK.
1690 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1691 Changed prototype Z3950_records. For some functions, int parameters
1692 were changed to size_t.
1694 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1697 New MARC decode/display function, marc_display_exl, which properly rejects
1698 non-ISO2709 records. YAZ client uses it.
1700 --- 1.8.1 2001/10/29
1702 Fix bug: local attribute set wasn't set correctly in PQF strings.
1706 * Old Z39.50 codecs no longer supported.
1708 Added ZOOM C binding. See http://zoom.z3950.org/
1710 Renamed states for COMSTACKs to avoid confusion with events.
1712 Implemented cs_look and proper cs_rcvconnect.
1714 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1716 Configure detects POSIX threads on OpenBSD.
1718 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1719 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1721 When error is returned from present handler, non-surrogate diagnostic
1722 is returned in present response (and fetch handler is no longer called).
1724 * Minor adjustments to pquery parser (PQF). Token characters may be
1725 escaped by using backslash (C-style).
1727 PQF parser allows string attribute values to be specified. For @attr,
1728 non-numeric characters after the equal-sign are treated as strings
1729 (e.g. @attr 9=title).
1731 CCL trunction character may be defined (@truncation in file)
1733 * function zget_ExtendedServicesRequest sets waitAction to
1734 waitIfPossible (was wait).
1736 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1739 CCL operator names may be set in field definition files (CCL_bibset).
1740 See ccl/bib1 for an example.
1742 Fixes in ASN.1 compiler for C++ compatibility.
1744 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1745 and "op_or" to avoid conflict with C++.
1747 Fixed problem with GNU readline detection on Redhat 7.0.
1749 Added step-size for Scan backend handler.
1751 Fixed bug that made the frontend server crash when no attribute
1752 set was specified for scan.
1754 Front-end server automatically switches to original working directory
1755 when installed as an NT service. Previously -w had to be specified to
1758 Added extended attributes for retrieval module (data1), so that data1
1759 records carry d1_readXML/SGML attributes. d1_read also supports
1760 null-data rules ( <tag/>)
1762 On UNIX when POSIX threads are available, a separate library libyazthread
1763 is created. Programmers should link with that library and the yaz library
1764 when using threads. The reason for the split was that some applications
1765 on Linux, such as Apache, doesn't work well when using shared objects that
1768 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1769 (or any frontend server) in SSL mode by specifying ssl: followed by
1770 address. Only tested on UNIX.
1772 Added feature for CCL module. Virtual structure s=al or s=ol generates
1773 and-list and or-list respectively instead of phrase search.
1777 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1778 log_mask_str. This was done to avoid name conflicts with other libraries
1779 (such as other PHP extensions).
1781 Added raw OID member for preferred record syntax (request_format_raw)
1782 and returned record syntax (output_format_raw) for backend fetch method.
1784 Config file yaz-config now accepts options so that it returns specific
1785 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1787 Shared library support for UNIX using GNU libtool.
1789 * Modified backend interface. Request/Response struct's replaced by
1790 one read/write C struct. For example bend_fetchrequest and
1791 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1792 Every handler - even search has to be registered in bend_init
1793 handler. This means that the YAZ library no longer refers to
1794 external functions and it makes it possible to make the whole
1795 thing a single DLL/SO.
1797 Added Segment handler for backend server.
1799 Added Zmbol/Zebra administrative functions to YAZ client.
1801 Threaded frontend server on UNIX (when POSIX Threads are available).
1802 Starting the server with option -T enables multi-threading.
1806 Added configure option --enable-comp/disable-comp to control use
1807 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1808 located in sub directory asn.
1810 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1811 in ${exec_prefix}/bin along with the other programs yaz-client and
1814 GNU automake used to maintain makefiles.
1816 Added several OID's.
1818 Changed retrieval module so that we can load records with no abstract
1819 syntax defined. Tagpaths in these records are fully composed of string
1822 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1826 On UNIX, the generated makefile now supports a proper 'make install'.
1827 The prefix can be set via GNU configure to set the install location
1828 (default is /usr/local).
1830 * YAZ programs client and ztest were renamed to yaz-client and
1831 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1832 locations, such as /usr/bin,/usr/local/bin,etc.
1834 * YAZ Header files were moved from include to include/yaz. YAZ Header
1835 files are referred to as include <yaz/log.h> rather than <log.h>.
1836 The YAZ include path (-I ..) is therefore the same as before. Programmers
1837 should update their #include statements or use -Ipath/include/yaz
1838 instead. The main motivation for doing this change is that YAZ header files
1839 can be installed in "standard" locations /usr/include,/usr/local/include
1840 without introducing conflicts, since ALL YAZ header files are stored
1841 in subdirectory yaz (under /usr/include for example).
1843 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1844 rather than project/workspace files. We switched because project files
1845 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1848 Changed name of logging function, logf, to yaz_log, to prevent name
1849 clash with some math-log functions. The YAZ header log.h defines logf
1850 to yaz_log (#define) so there should be no incompatibilities by this
1853 Added bend_start/bend_stop handlers for server. These handler are
1854 called on start/stop of server. For windows they are called whenever
1855 a service is started/stopped.
1857 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1858 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1859 in util/yc.tcl. The auto-generated C code structures are, in a few
1860 cases, incompatible with the old decoders. There are differences in the
1861 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1862 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1863 The preprocessor variable ASN_COMPILED is defined when the compiled
1864 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1865 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1866 wish to use the old encoders/decoders you can specify --disable-yc
1869 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1870 version so that it supports both new - and old version of DB Update
1872 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1873 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1874 change. The name parameter can be set to 0 in which no name is specified
1875 for the construction. The macros odr_implicit and odr_explicit sets name
1876 parameter to zero for the construction involved. New macros
1877 odr_implicit_tag and odr_explicit_tag are similar to the others,
1878 except that a name parameter is added. For programmers' that don't use
1879 ODR they probably only need to change the call to z_APDU and z_External.
1881 Added access control facility by interfacing the TCP wrapper library.
1882 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1883 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1884 name of the daemon and enables the access control as specified in
1885 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1887 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1888 den Dool <H.M.vdnDool@kub.nl>.
1890 Added reference ID parameter to most functions in server API - refer
1891 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1893 Changed name of ccl library to libccl.a (was ccl.a).
1895 Fixed bug in decoder for Explain (Category TargetInfo).
1897 Added support for GNU readline in client. Thanks to Jacob Poulsen
1898 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1900 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1901 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1902 IMPLEMENTATION! This change was made to the development version before
1903 the ZIG decided to retract the amendment. If any users MUST be
1904 compatible with the original Update definition, PLEASE CONTACT US, and
1905 we will include a separate definition corresponding to the old Update
1906 ES. Note that because of the change to the ASN.1 of the
1907 TaskPackageRecordStructure we cannot define a single structure that
1908 will support both versions.
1910 * Added const modifier to buffer parameter for some ODR/BER encoding
1911 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1912 completeWAIS, odr_dumpBER.
1914 Fixed bug in client.c which caused a crash when a scanResponse didn't
1915 contain positionOfTerm.
1917 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1918 * will cause an error in a client if a non-YAZ target sends both a
1919 * list of Scan entries and non-surrogate diagnostics.
1921 Retrieval module enhancements. Tag sets may be typed in the reference
1922 to it. From the .abs-file the "tagset" directive takes a third optional
1923 integer type for the tag set referenced. From a .tag-file the "include"
1924 directive takes a third optional type as well. The old "type" directive
1925 in the tag set itself is still recognized but acts as the default type
1928 Backend interface change. Individual Scan terms returned from bend_scan
1929 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1930 in include/backend.h.
1932 Retrieval module enhancements. Multiple tag sets and attribute sets may
1933 be specified in abstract syntax specs. Revised the error/warning for
1934 logging messages reported by the retrieval module when reading the
1937 Object Identifier system (oid_..) changed. The API is backwards
1938 compatible but the oid-routines now allocates new OID's when needed.
1939 Raw OID's may be specified in oid_getvalbyname.
1941 YAZ now uses GNU configure to generate Makefile(s).
1943 * Minor changes in some of the member names of DeleteResultSetRequest and
1944 DeleteResultSetResponse. See include/proto.h.
1946 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1947 and added member 'languages' in TargetInfo (which was missing).
1949 Changed the way attribute sets are handled in the retrieval
1950 module. These are now cached, just like the abstract syntaxes
1953 Changed YAZ so that it links with compiled ASN.1.
1955 Added Explain-schema definitions and mapping routines. The following
1956 Explain categories have been implemented: AttributeDetails,
1957 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1959 Fixed minor bug in Windows version of Server Library.
1961 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1963 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1965 Added EXTERNAL: UNIverse Resource Report (non-standard).
1967 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1968 ENUMERATED and SET OF.
1970 * Added 'const' to some of the char pointer arguments for the
1971 functions, data1_read_node, data1_getelementbytagname,
1972 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1975 Fixed bug in data1_insert_taggeddata - the last_child member of
1976 parent wasn't initialised.
1978 * Changed data1_read_record and data1_read_node so that the supplied
1979 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1980 doesn't refer to any parts of the "SGML"-buffer.
1982 Fixed bug in server library (Windows version of statserv_remove).
1984 * Changed code so that it compiles as C++. The type definition
1985 of Odr_fun which is a member of Odr_arm was changed. The result is,
1986 that an explicit typecast is needed for the fun pointer when
1987 using Odr_arm - as in:
1988 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1990 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1992 Implemented the new structured date and time definition as approved
1993 by the ZIG. Added schemaId element to the specificTag in Espec-1
1994 (also approved at the last ZIG). Thanks to RVDM.
1996 Added some Object identifiers (RVDM).
1998 Changed the Update Extended Service (RVDM).
2000 Added command "refid" to client which specifies referenceId for
2001 the following requests.
2003 Implemented extended service handling for server. See ztest.c
2004 for an example as well as backend.h. New handlers are registerd
2005 in the Init handler.
2007 * Changed interface for sort in server.
2009 Added new members to statserv_options_block. It allows a server
2010 to read options from another source than just the command line. Thanks
2011 to Charles Woodfield.
2013 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2014 renamed to zboolean. Some C++ compilers complained about the name.
2016 Minor changes to gils.abs. Added index 's' (sort) on title
2017 and date/time-last-modified.
2019 --- 1.4pl2 1998/1/30
2021 Fixed bug in server library regarding inetd mode (-i). This bug
2022 was introduced by release 1.4.
2024 --- 1.4pl1 1998/1/29
2026 Added sort facility in client and backend server interface.
2028 Fixed problem with dependencies in Makefile(s).
2030 Fixed bugs for encoders/decoders of extended services and
2033 Implemented sub-tree feature for schemas. Sub-trees are
2034 referenced in *.abs-files. See explain.abs for an example
2035 of the use of this feature.
2037 Modified bib1.att; local attributes for ANY didn't include
2038 ANY itself (only affects use of the retrieval module).
2040 Fixed bug in plain SGML reader in function data1_read_node:
2041 tags with prefix "var" was incorrectly interpreted as variants.
2043 Added feature "sub-schemas" to enable references to - and definitions
2044 of - group of elements.
2046 * Removed member parent from type data1_element (in data1.h).
2048 Implemented function odr_nullval() that returns the value of
2051 * Removed member num_children from data1_node (in data1.h).
2053 Made NT service interface part of the server library. The
2054 function statserv_main uses the NT service when required and
2055 calls the statserv_start / statserv_close routines.
2057 Routine zget_SearchRequest and zget_PresentRequest fills
2058 resultSetName/Id member with "default" instead of "Default".
2060 Fixed memory leak in server. Request queue member wasn't freed.
2062 Fixed nmem_exit so that memory is freed.
2066 Revised the CCL parser utility to be thread safe.
2068 Added function, oid_ent_to_oid, to replace the function
2069 oid_getoidbyent, which is not thread safe.
2071 * Added nmem_init and nmem_exit to initialize and release
2072 NMEM resources. Function nmem_init should be called once in the
2073 initial thread before NMEM/ODR is used. statserv.c and client.c
2074 have been changed accordingly. The change was necessary to make
2075 NMEM thread safe. The NMEM memory pool is shared amongst threads
2076 in a process. Unix-based applications will still work fine without
2079 Added NT Services interface for the the Z39.50 (statserv) Server.
2080 Refer to the ztest.c source on the usage.
2082 Windows 95/NT port using MSVC5.0. Project files are included in the
2085 * Defined new 'global' handle for the retrieval (data1) system. The
2086 new handled, data1_handle, describes the state of the data1 system.
2087 This handle is passed as first argument to virtually all
2088 data1 related routines. The functions data1_create and data1_destroy
2089 creates and destroys a data1 handle respectively.
2091 Added ODR encode stream member to all backend request structures
2092 init, search, scan etc. This stream should be used to allocate all
2093 memory used for the response when thread safe operation is needed.
2095 Changed the comstack utility, cs_addstr, to be thread safe. The
2096 returned hostname string returned by the function is now part the
2099 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2100 function. The cs_straddr takes a COMSTACK handle as argument, so this
2101 function must be used after cs_create and before bind/connect.
2102 This function is thread safe.
2104 Moved test server to 'ztest' directory - generic server code still
2105 in 'server' directory.
2107 Made prefix query (pquery.c) utility thread safe.
2109 Added new function modifier YAZ_EXPORT to 'export' public DLL
2110 functions when using windows (see include/yconfig.h).
2112 Added definitions to the OID database (util/oid.c) (RVDM).
2114 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2116 Added call to ccl_rpn_delete in client program.
2118 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2119 release of RPN structure.
2121 Added support for C++, headers uses extern "C" for public definitions.
2122 With input from RVDM.
2124 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2125 Thanks to Ronald van der Meer (RVDM).
2127 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2129 Added support for private extensions to the OID database
2130 (oid_setprivateoids()). Thanks to RVDM.
2132 Added optional, physical ANY (key replication)
2134 Fixed null-reference problem in GRS-1 output filter.
2136 Proximity operator added to Prefix Query Format (PQF).
2138 In test client command "base" accepts multiple databases.
2140 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2144 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2146 Smallish bug-fixes in the new encoders/decoders (explain).
2148 Bug fixed in DeleteRequest.
2150 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2152 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2154 Added SOIF syntax (using private OID for now) to retrieval module and client.
2156 Added Update extended service.
2158 Added SearchResult-1 additional info structure.
2160 Added optional CCL (ISO8777) interpreter as separate module. Available
2163 --- 1.2 1996/6/10 (1st anniversary release)
2165 Added Summary record syntax. Lightly tested.
2167 Added OPAC record syntax. Untested.
2169 Added ResourceReport service encoders/decoders. Untested.
2171 Fixed bug in z_Unit - wrong tagging on unitSystem.
2173 Fixed bug in the DiagRecs decoder.
2175 Added options for max PDU size and session timeout to frontend-server.
2177 Added documentation of query-language parsers and other supporting utilities.
2179 [frontend-server] Added Attribute set to the bend_scanrequest API.
2181 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2182 surrogate diagnostics were generated.
2184 [retrieval] Allow multiple local values for attribute.
2186 [retrieval] Allow multiple attributes per element in .abs files. index type.
2188 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2190 --- 1.1pl2 1996/4/10
2192 Minor changes, mostly specific to Zebra's requirements (retrieval)
2196 Repaired bug in frontend server when running multiple listening
2197 endpoints in dynamic mode.
2199 z_External() now won't break if a known, ASN.1 value comes encapsulated
2200 in an octet-string. The value will pass through unmodified in an Odr_oct.
2202 Added a bit of code to the demo client to decode & display
2203 ASN.1-structured records represented in the octet-aligned branch of
2204 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2206 Added z_ext_getentbyref() to the ASN module. Doc updated.
2208 * Completed the SCAN definition in the ASN module. This may break SCAN
2209 code based on older YAZ-versions at compile-time. The fix is easy -
2212 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2213 under the SCAN definition. Remember to initialize this, server-people.
2215 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2216 that this does not extend to ODR and ASN.
2218 Comstack allows insertion of established socket (primarily for
2219 inetd-operation of servers). Doc updated.
2221 Front-end server can now start from the inetd in TCP mode. Doc
2224 --- 1.0pl4 1996/1/24
2228 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2229 the rank and record number.
2231 Adjustments to the frontend server.
2233 Fixed diagnostic BER dumper. It ignored the file argument.
2237 Various changes to retrieval module.
2239 Changed the union discriminators of the protocol files from enums to
2240 ints paired with #defines.
2242 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2245 *Changed operator in the RPN structure to 'roperator', again to avoid a
2248 Fixed problems in Explain decoders/encoders.
2250 --- 1.0pl2 1995/12/6
2252 Memory bug in log module fixed.
2254 --- 1.0pl1 1995/12/5
2256 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2258 Bug in Explain DatabaseInfo module fixed.
2260 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2264 The shift to v1.0 signals that we now consider the *core* functionality
2265 of YAZ reasonably stable (the core being more or less equivalent to
2266 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2267 tested (Explain not at all - though that will happen soonish).
2269 Minor changes to code to support Windows port.
2271 Various minor changes after we're getting to use GRS-1 & co. more.
2273 Added Espec-1 format.
2275 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2276 of the protocol and it cannot be selected when encoding (maps into 'string'
2277 when decoding). Needed to talk to some servers.
2279 Demo client can request simple element set names.
2281 Added Diagnostic Format encoders/decoders.
2283 Added simple Close handling to frontend server (no hooks for resource
2284 reporting yet), and demonstration client.
2286 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2288 --- 1.0b3 1995/08/24
2290 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2291 handled incorrectly when records were requested in the searchResponse. This
2292 will only affect you if you use the frontend-server.
2294 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2295 Test-client will ask for and print GRS1. Ztest will return dummy records
2298 Added Explain encoders/decoders to the service-level API. Untested.
2300 Added Extended Services: Item Order encoders and decoders to the Service-
2301 level API. Untested. We could use a recent copy of the pertinent bits
2302 of the ILL protocol to add those bits.
2304 Added diagnostic format 1 encoders/decoders to the service-level API.
2307 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2308 odr_cons.c, which causes a more correct output.
2310 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2311 was always set to 0 when no records were requested in the searchRequest.
2313 * Added better external-handling. This shouldn't harm old code that
2314 *encodes* externals. It can break code that looks for a
2315 'single-ASN1-type' representation, since those types that are known
2316 are now decoded immediately. Look at the SUTRS sample code in
2317 seshigh.c and client.c. Documentation updated.
2319 Handling of structured records in bend_fetchresponse. Length -1 marks
2320 structured record, type is deduced from format field.
2322 --- 1.0b2 1995/06/27
2323 Fairly quick maintenance release to add SUTRS support.
2325 Fixed handling of SUTRS records in the demonstration client.
2327 * Added format field to the bend_fetchrequest and bend_fetchresponce
2328 structures of the backend API (frontend server). When the record is
2329 returned, the value of the format field is mapped to an OID. The
2330 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2331 of the record. The special value VAL_NONE in the bend_request means
2332 that no specific format was requested by the client. Documentation
2333 updated accordingly. Test server (ztest) will return a fixed dummy
2334 SUTRS record if your client requests SUTRS.
2336 Documentation updated accordingly.
2338 You can now set external libraries and RANLIB support in the top-level
2342 First public release.
