3 Fixed bug #2027: Crash when closing connection.
5 Changed configure so that ICU support is only enabled if only ICU
6 and Libxml2 is available (because the ICU chain is XML based).
10 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
11 is built. Only this DLL depends on the ICU runtime.
13 yaz-ziffy is no longer part of YAZ. It is distributed separately by
14 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
16 Changed license of CCL module to 'Revised BSD'. After consultation with
17 remaining members of the original EUROPAGATE consortium, we are re-issuing
18 the CCL module without a separate license. The software was developed by
19 Index Data as part of a research project. The special license was included
20 to help feed usage information back to the project consortium to support
21 project evaluation. At this time, the project consortium has long-since
22 disbanded, and the majority of the original principals have retired. At the
23 same time, we have significantly modified the software during the following
24 years, to the point where very practically no original code remains. To
25 simplify re-use of the software, we have contacted those members of the
26 consortium who could be reached, and agreed to re-issue the module as a
27 proper part of the YAZ package.
29 Tcl scripts uses /usr/bin/tclsh as preferred shell.
31 CQL closer to being version 1.2 compliant. CQL also allows free-form
32 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
35 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
36 bug could make Extended services handling crash in the ZOOM layer. This
37 bug was only present in YAZ 3.0.18.
41 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
44 yaz-marcdump reads and writes collection wrapped records.
46 Handle OPAC for record conversion module.
48 Fixes for ICU wrapper.
50 Allow ICU libs to be controlled with --with-icu .
54 Added yaz_poll which is a wrapper for select/poll. When poll is available
55 and non-buggy, it is used, by yaz_poll . This allows more than 1024
58 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
59 functionality through an XML based configuration (ICU chain). This system
60 is useful for search facilities such as Pazpar2 and Zebra that needs to
61 perform tokenization of indexed material. The ICU code in a separate
62 library libyaz3_icu.a.
64 Added HTTP tunnel facility for COMSTACK, bug #1752.
65 This is a facility that allows a Web proxy, such as squid, to tunnel
66 Z39.50 traffic. This facility is "transparent" to must applications
67 using YAZ. It's enabled by using pseudo transport connect: followed by
68 the proxy address, followed by command, then follwed by he regular
69 "virtual" addresss. For example,
70 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
72 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
76 Fixed bad memory reference in ZOOM_record - cuased by member not being
77 initialized. This was a problem only in YAZ 3.0.12.
79 Fixed bug in conversion from MARC to XML: Non-XML characters in control
80 fields were not removed.
82 Changed the way C code is generated from codetables.xml. Made a MARC-8
83 conversion trie for each characterSet section rather than codeTable.
84 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
85 of codetables.xml from Larry Dixson, LOC. Bug #1464.
89 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
90 from ZOOM_record_error).
92 ZOOM C function ZOOM_record_get returns record schema for type="schema".
94 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
96 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
98 Better SRW-to-Bib-1 diagnostic mapping.
100 ZOOM C and yaz-client announces SRU version 1.2 by default.
102 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
105 Fixed in yaz_sru_decode to allow other version than 1.1.
107 --- 3.0.10 2007/08/22
109 Added support for SRU scan for ZOOM.
111 Added support for the use of the older versions or Extended Service
112 Update in ZOOM. To faciliate this, an option "updateVersion" may be
113 set to the version , 1=first, 2=second, 3=third. The third version is
114 what ZOOM C has used so far. And that, obviously, is the default.
116 Added support for CCL queries in Z39.50 queries sent to the GFS (and
117 therefore in Zebra and in SimpleServer-based applications). The new
118 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
119 qualifier file used to transform incoming CCL queries into Type-1 RPN,
120 which is passed into the back-end search callback function.
122 Added support for HTTP Basic authentication in clients: the SRU/W
123 codec encodes the username/password elements of the PDU structure
124 appropriately, and these may be set using the "user" and "password"
125 options in ZOOM-C applications (the same options that are used for
126 Z39.50 authentication).
130 Fixed bug #1208: SSL appears to be broken in ZOOM.
132 Fixed bug #1206: Libxml2 include path weirdness.
134 Added oid_name_to_dotstring.
136 Allow elementSetName to be specified for ZOOM C record update.
138 Allow waitAction to be specified for ZOOM C based for Extended Services.
140 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
141 syntax OID. Bug introduced in YAZ 3 series.
143 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
147 Fixed bug #1157: yaz-client does not read .yazclientrc from current
148 directory. yaz-client now reads commands from file given by option -f
149 if specified; then tries to read .yazclientrc in current directory.
150 Failing that, it reads .yazclientrc from user's home directory.
152 Added support for correlationInfo Note and ID for Record Update via
155 Added yaz-client command querycharset which specifies character set for
156 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
157 (termListAndStartPoint).
159 Charset ISO5428:1984 is an alias for ISO5428-1984.
161 Implemented a way to perform scan in a result set using Z39.50. This
162 is achieved by attaching the result set name in the characterInfo
163 (type InternationalString) of OtherInformation in the Scan Request PDU.
164 The result set is identified in the otherinformation by the new OID:
165 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
166 This allows for scan in result set and faceted search . Zebra did some
167 of this in the APT term using attribute type 8 and value being result
168 set. Using the OtherInformation approach for this is cleaner and easier
169 to work with in proxies and the like. This facility can be used in
170 yaz-client using new command setscan which takes a result set as first
171 argument, start position (APT) as second.
173 Changed decoding of SRU XML packed records to deal with servers that
174 have recordData with XML data with multiple root nodes. Also make
175 comparison for recordPacking case insensitive. Again, one server
176 returns "XML" where others return "xml".
178 For SRU responses allow Content-Type application/xml as well as text/xml.
182 Fixed bug in character set conversion of BER strings. Bug introduced
187 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
189 For OID class, use oid_class consistently.
191 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
194 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
195 character set for bibliographic information interchange". By Giannis Kosmas.
197 Added documentation on new OID API.
201 Changes to generic frontend server interface: added new member
202 'query_charset' for bend_initrequest structure. A backend init handler
203 should set this member to its native character set for query terms.
204 When defined, the frontend server logic will announce this character set
205 to a client if the negotiationModel bit is set by the client. All server
206 implementors are encouraged to specify this. If a backend server does not
207 specify this a warning is issued using yaz_log(YLOG_WARN,..).
209 Added CCL utility to remove terms (stop words) from resulting RPN
210 tree. This is handled by functions with prefix ccl_stop_words_ .
212 New ZOOM C option, "rpnCharset", which allows client-side conversion of
213 terms in RPN queries.
215 Clean-up the CCL API. Moved some internal structures from ccl.h to
216 private header cclp.h. Changed ccl_parser_create so that a Bibset must
217 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
218 This is replaced by ccl_parser_find_str which takes a string instead.
220 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
221 libyaz.la is the core of YAZ except the generic frontend server and
222 does not depend on POSIX threads anymore. libyaz_server.la is the
223 generic frontend server facilities and uses POSIX thread functionality
224 if available. The libyaz.la no longer depends on POSIX threads because
225 the number of global structures is limited. NMEM no longer re-uses blocks
226 between threads ; it simply free's memory immediately but allocates in
227 "large" chunks as usual. We don't expect any performance penalties
228 because of this. The yaz_log system is still using a global log_level so
229 caution must be taken when modifying it with yaz_log_init_.. +
230 yaz_log_mask_str. This, however, should not cause any trouble because
231 these functions are called during initialization of application code
232 anyway. `yaz-config --libs server` returns libs for server applications;
233 `yaz-config --libs` returns libs for non-server applications.
235 New OID database - with public definitions in oid_db.h. Removed old OID
236 database including the head oid.h and definitions such as enum oid_value
237 and struct oident. The new OID database uses the same string names as
238 before but the 'protocol' is gone. There are now only two representations
239 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
240 converts from string to OID; functions with prefix yaz_oid_to_string
241 converts the other way.
243 Change to emit_term() in CQL-to-PQF query translation: when a term has
244 the /regexp relation modifier, do not process it for leading and
245 trailing "^" and "*", which have quite different meanings in regular
248 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
249 write handlers no longer carries a 'last' parameter. This will make
250 yaz_iconv flush "less" characters. A flush is performed by call to
251 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
253 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
254 removed, because function yaz_query_to_wrbuf does the same.
256 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
257 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
259 Deprecated MARC utility functions removed.
261 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
264 Branch split: YAZ_2_1_55_branch
266 --- 2.1.54 2007/03/16
268 Fix to ZOOM-C so that transparent reconnection is properly handled on
269 connections that are in asynchronous mode.
271 Fixed compilation on OpenBSD 4.0.
273 Large strings in GRS-1 records are now properly displayed in yaz-client.
275 Added character conversion support for "advancegreek"; based on patch from
278 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
279 sequence is met. Before the error was not set so it would be unknown.
281 Adjust yaz-marcdump MARC reader so that it skips until record separator
284 --- 2.1.52 2007/03/07
286 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
287 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
288 fd_set structure used as a bitmask for the FDs to be selected on.
290 Using ACX_PTHREAD macro to check for POSIX threads.
292 Fixed have-vsnprintf check.
294 --- 2.1.50 2007/02/23
296 Fixes for configure on BSD. Bug #900.
298 Added snprintf/vsnprintf wrappers for systems that don't have
299 limits (heavens forbid).
301 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
302 created before all previous tasks were completed and removed from the
303 task queue, the new task could be removed by a mistake.
305 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
307 Implemented pass-through CQL-to-PQF conversions. Bug #861.
309 Fixed bug #832: Problem with MARC/charset in yaz-client.
311 Fixed bug #668: save command line history for yaz-client.
313 Fixed bug #830: pkg-config support.
315 --- 2.1.48 2007/01/23
317 Extended ZOOM result set options with two options that may be read by
318 a client: resultSetStatus and presentStatus with values as specified for
320 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
322 Fixed bug #827: Using SSL fails on Debian etch.
324 Fixed bug #826: Weird looking chars for set of MARC records.
326 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
327 that is treated as an ItemOrder with itemRequest being an XML document
328 external. The value of "doc" is the content.
330 Extended the GFS search facility. New member of bend_search_rr
331 'estimated_hit_count' signals that hits is known to be an estmate
332 (higher or lower than real hit count). New member 'partial_resultset'
333 signals that the search was partial (hit count is lower or equal than
334 real hit count). For Z39.50, the information is stored in resultSetStatus
335 member of SearchResponse APDU. For SRU, the information is signalled
336 via SRU diagnostic 59: "Result set created with valid partial results
339 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
341 --- 2.1.46 2007/01/13
343 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
345 Added ZOOM_connection_peek_event.
347 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
348 the following new functions:
349 ZOOM_event_nonblock, ZOOM_connection_process,
350 ZOOM_connection_get_{socket,mask,timeout},
351 ZOOM_connection_fire_event_{timeout,socket}.
352 The existing blocking event handler, ZOOM_event, is a wrapper for the
353 + blocking ZOOM_event_sys_{poll,select}.
355 Implemented function ccl_xml_config which parses XML version of CCL
356 configuration (bug #798).
358 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
360 Added timings utility (yaz/timing.h)
362 --- 2.1.44 2007/01/03
364 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
367 Fixed bug #779: Rotation of apdu.log fails.
369 Fixed for character set conversions:
370 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
371 Honor G1 set in MARC-8 decoding.
373 --- 2.1.42 2006/12/17
375 Fixed bug #775: char conversion does not handle Alternative UTF-8
378 Implemented function yaz_marc_read_line which parses MARC line format
379 records. There is a wealth of formats out there. So far, this function
380 reads line records produced by yaz_marc_write_line.
382 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
383 more generic and easier to remember(!) options: -i format and -o format
384 which specifies input format and output format respectively - where
385 format is one of "marc", "marcxml", "line", "marcxchange".
387 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
388 does not print anything except warnings for records.
390 For yaz-marcdump, added support for MARC split into files (-s) with a given
393 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
394 spec, at http://www.loc.gov/standards/sru/record-update/
395 This has changed the binary layout of the following structs:
396 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
397 bend_update_rr . Patch by Ko van der Sloot.
399 Added GFS utility function bend_assoc_is_alive which returns 1 if
400 association is still alive (client is connected); 0 otherwise (client
401 closed connection). This allows busy servers to stop working for
404 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
405 been a separate piece of software. This version of ziffy has been modified
406 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
408 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
410 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
411 Client code may now interrogate options such as "init_opt_sort" to
412 find out whether the server claims to support various options.
414 --- 2.1.40 2006/11/27
416 Added utilities yaz_{set,get}_esn to set/get element set name from
419 Removed the build of libyazthread.la. The libyaz.so is the threaded version
420 of YAZ and has been so since YAZ 2.1.10.
422 Implemented ZOOM_record_error which returns error information for
423 record (surrogate diagnostic).
425 --- 2.1.38 2006/10/31
427 Updates for SRU Update by Ko van der Sloot:
428 1. Changed name from "operation" to "action"
429 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
430 versions in the code, marked as 'backward compatible'.
431 3. Added diagnostics for SRU Update.
433 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
435 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
437 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
439 For GFS, fixed problem with SRU diagnostic 'First record position out of
440 range' being issued for 0 hits.
442 zoomtst10 part of Windows Build.
444 --- 2.1.36 2006/10/13
446 Implemented yaz_filepath_comp which splits a path into file path
447 components (required by Zebra 2.0.3+).
449 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
450 BSD inspired license until now so this should not have any real impact on
451 anybody. See http://www.opensource.org/licenses/bsd-license.php
453 Fixed bug #687: Missing log lines.
455 Fixed bug #678: CQL to PQF translation does not preserve double-quote
458 Fixed bug #689: SRU diagnostics to be added.
460 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
461 whether a connection is idle (no more work do do).
463 --- 2.1.34 2006/10/04
465 Change type of optval from long to int for invocation of setsockopt with
466 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
468 Added support for specifying the max log file size for the Generic
469 Frontend Server. The size is given with option -r.
471 --- 2.1.32 2006/09/21
473 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
475 --- 2.1.30 2006/09/17
477 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
480 Fixed bug in Generic Frontend Server that could cause a server to stop
481 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
483 For the generic frontend server, the maximum record size is used as maximum
484 size of incoming packages (SRU + Z39.50). The value until was previously
485 only used in Z39.50 Init negotiation and, later, in a session controlled
486 sizes of records returned. This is controlled using -k option. It can be
487 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
489 --- 2.1.28 2006/09/04
491 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
494 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
496 New option for yaz-marcdump -lpos=value which allows setting a portion
497 of MARC header to a certain value.
499 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
501 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
502 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
504 --- 2.1.26 2006/08/15
506 Fixed problem with SRU mode type (soap, get, post) for yaz-client
509 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
511 --- 2.1.24 2006/08/08
513 Fixed MARC ISO2709 encoding routines to deal with character set
516 Minor changes to GFS logging. Database included in search request log
519 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
520 cached/multiple records.
522 Shared libraries are built by default on Unix+configure.
524 Changed cql2pqf transformation to use a different evaluation order. The
525 new order is: always, relation, structure, position, truncation, index
526 and relationModifier. Old order was: always, relation, relationModifier,
527 structure, index, position, truncation. Note that the the latter ones
528 override former ones for identical attributes.. The new scheme means that
529 it is possible to override any existing attribute with a relationModifier.
530 And also that it is possible to override everything for the index rule
531 (except the ones listed in relationModifier). No order is perfect but this
532 one, we believe, covers more real cases.. The "always" should have been
533 called "default", since the attributes there can be overridden with all
536 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
537 compilation phase, but also for yaz-config --cflags output. This allows
538 us to have public headers with Libxml2 stuff in them . It should also,
539 eventually, make Libxml2 checks redundant in packages using YAZ, such
542 --- 2.1.22 2006/06/15
544 Changed SRU update structure bend_update_rr so that SRU diagnostics are
545 stored in uri, message and details.. Previously diagnostics were stored
546 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
547 compatibility.. but he's probably the only one affected, so.
549 Added support for CCL, compiled on the client side, in ZOOM-C. This
550 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
551 input; the resulting query objects can be used for for searching with
552 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
554 YAZ' configure searches for OpenSSL by default.
556 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
557 SL_CTX_use_certificate_file. See
558 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
559 for more info. Thanks to Ko van der Sloot.
561 --- 2.1.20 2006/06/02
563 Bug #600: SRU GET, POST support for yaz-client. Introduced
564 command 'sru' which selects method SOAP/GET/POST.
566 Allow missingValueAction to be specified for the sortspec string -
567 function yaz_sort_spec. By default, the missing value action is null.
568 Use ! to specify "abort". Use = followed by stringvalue to specify default
571 Ensured that Present-handler (if defined) is called in GFS before any call to
572 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
573 searchRetrieve requests.
575 Documentation for YAZ is now based on the Docbook XML/XSLT using
576 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
577 is no longer depending on jade/openjade or docbook-to-man scripts.
578 PDF is no longer part of the distribution - but can optionally be
579 made using DSSSL/jadetex or FOP.
581 Added retrieval handling support in Generic Frontend Server to support
582 conversion between MARC/XML as well as XSLTtransforms. See
583 etc/yazgfs.xml for an example.
585 Added Authentication support to Generic Frontend Server in SRU
586 mode. Authentication using HTTP Basic is supported, as is the use
587 of 'x-username' and 'x-password' parameters in the request itself.
589 Added support for a new character set MARC8s identical to MARC8 except
590 that it converts combined characters to single Unicode characters in the
591 Latin-1 range (when possible).
593 --- 2.1.18 2006/04/24
595 ASN.1 compiler 0.4: generates brief Doxygen file header for
596 generated .h/.c files.
598 Utility yaz_iconv now supports conversion to MARC-8.
600 New facilities for the MARC module. The reading - and writing of
601 content are separate methods for the yaz_marc_t handle. The following
602 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
603 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
604 format). Write functions have prefix yaz_marc_write_.. The existing
605 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
606 available. Removed support for OAI-MARC and simplexml (not the
607 simplexml from PHP5).
609 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
610 to be returned for this connection.
612 --- 2.1.16 2006/03/31
614 Allow multiple languages and charsets to be specified with
615 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
616 negcharset iso-8859-1,utf-8
618 Translation of proximity nodes from CQL into PQF now works.
620 Moved to automake 1.8, 1.9.
622 Added function yaz_log_set_handler which allows a log handler to be
623 installed. This handler will be called for all log messages. Output
624 to file is also produced; but that can be disabled by passing NULL
625 fname to yaz_log_init_file.
627 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
629 For SRW (including GFS), accept application/soap+xml as content-type
632 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
633 produces NO stylesheet reference even if a default stylesheet is specified
636 --- 2.1.14 2006/03/14
638 Updated Windows package to include yazd.dll + yazd.lib for the
639 Development component.
641 If the environment variable YAZ_LOG is set, then it is used as a
642 string indicating the default level of logging to use if not
643 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
644 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
645 used as before. So, for example, to omit warnings from YAZ logging,
648 cql_transform() now map structure and other attributes before indexes,
649 so that index-specific structures and other attributes can override
650 defaults. So now a combination of mapping specifications such as:
652 index.dc.date = 1=date-modified 4=5
653 does the right thing.
655 cql_transform() now also respects the "always" mapping specification,
656 which establishes an initial set of attributes to be used for all
657 terms except where overridden by more specific attributes associated
658 with the index, relation or modifier.
660 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
661 which mode to use; one of "post", "get" or "soap" (SRW, default).
663 Fixes for yaz_iconv routines: changed trie-based character set conversions
664 to use only non-negative values for bit fields due to Sun's C compiler not
665 supporting negative values.
667 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
668 sequences where not read correctly. Fix by Rustam Usmanov.
670 Updated win/makefile to use options, settings which makes things
671 compile with VS C 2005.
673 --- 2.1.12 2006/02/01
675 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
677 In ZOOM socket code, use select instead of poll on MacOSX.
679 ZOOM-C now support client-side compilation of CQL into RPN that is
680 sent to the server, enabling CQL to be used against all Z39.50
681 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
682 ZOOM_query object, and submit it using ZOOM_connection_search().
683 The CQL-to-RPN translation uses a configuration file, the name of
684 which must be specified in the Connection's "cqlfile" option.
686 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
687 function, which takes as its start-term parameter a ZOOM_query object
688 (which may have had either CQL or RPN set into it).
691 --- 2.1.10 2005/11/29
693 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
694 GFS to support this as well. Backend handler, bend_srw_update, does the
695 update work. Code contributed by Ko van der Sloot.
697 Allow retrieval of Search Result-1 information in ZOOM by the use of
698 options that are attached to a result set. ZOOM documentation updated
701 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
702 UTF-8 conversion. Patch by Raj Patel.
704 Added option -m to GFS to control formatting of timestamps in log file.
706 Added 'exit' as synonym for 'quit' in yaz-client
708 Added support for specifying SRW resultSetId + resultSetIdleTime in a
709 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
710 for the new members. Patch by Ko van der Sloot.
712 Added support for SRU POST. It is supported for content-type
713 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
715 Do not build the separate Multi-threaded (MT) library libyazthread.la.
716 Instead make the library libyaz.la multi-threaded. Threading as a whole
717 can still be disabled by configure option --disable-threads. Previosly,
718 with older GLIBCs there were problems with MT libs under Apache. This
719 has now been fixed a long time ago.
721 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
724 CQL module modified to be case insensitive for relations/indexes/operations.
726 Fixed bug in CQL transform code: incorrect value relationModifieder
729 Added 'show all' command for yaz-client which retrieves all results
732 Added new yaz-client, xmles, which takes a (private) OID and
733 a document to be sent as an extended service request.
735 Describe new yaz-client commands wait_response and set_auto_wait.
737 Increase TCP/IP listener backlog from 3 (which I am guessing was
738 copied from the SunOS manual entry way back when) so SOMAXCONN, so
739 that the socket will queue as many incoming connections as it's able
740 to handle ongoing connections. In other words, it will never now
741 refuse a connection that it would be able to handle merely because
742 it's not got around to accepting() enough of the pending connections
743 yet. This is the behaviour anyway under Linux, where the listen()
744 argument is ignored; but not under BSD and on systems such as
745 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
746 YAZ-based servers should now be uniform across operating systems in
749 yaz-marcdump uses 64-bit file access on some systems. This is enabled
750 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
751 This allows yaz-marcdump to read large MARC batches (>2 GB).
753 Modified all YAZ source files - except the source which is auto-generated
754 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
757 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
758 corresponding to the existing *_setl() function. These allow option
759 values containing arbitrary valuues.
761 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
762 ZOOM_resultset_sort() in new applications. Its behaviour is identical
763 except that it returns an indicator of whether or not the sort
764 criterion was accepted (0 for OK, -1 for invalid).
768 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
769 MARC output rather than returning "new" buffer.
771 yaz-client warns about unknown init options.
773 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
777 Added support for SRW sort in Generic Frontend Server. Patch
778 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
779 sortKeys - or NULL if none is provided.
781 Fixed bug #307: It was impossible to specify indefinite/no timeout
782 for ZOOM_event. Special timeout value -1 now means indefinite timeout
785 Added support for multiple languages and charsets to be specified in
786 ZOOM. Each charset/language is separated by a blank. If negotiation is
787 in effect in init-response, Option
788 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
789 Code based on patch by Vasiliy Osadchuk.
791 Fixed bug #306: infinite recursion that occurred when calling
792 yaz_log_level_init as the first call (before other log level or
795 Fixed bug in scan handling in front end server: if preferred-Position-In-
796 Response was non-present, a NULL pointer referece was performed.
800 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
801 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
802 now defined for all those error codes. So instead of putting 109 in
803 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
804 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
806 Modified the yaz-marcdump utility to skip garbage bytes between MARC
809 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
811 Program yaz-client now exits and produces an error message if multiple
812 Z39.50 servers are specified on the command line (none or one allowed
815 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
820 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
822 Fixed bug #272: Preserve spacing for CCL terms.
826 Added support for virtual hosts and multiple backend servers for
827 the YAZ frontend server. The configution is XML based and
828 support specificition of CQL to RPN mappings and explain information.
829 See section "Virtual Hosts" in the YAZ manual.
831 Extended OPAC display utility. OPAC display utility renders
832 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
833 to supplement yaz_marc_decode_wrbuf.
835 Fixed a bug in MARC decoder that could caused it to crash for some
836 invalid MARC records. More diagnostics and warnings where added in
837 XML output (warnings, etc are stored in comments).
839 --- 2.0.34 2005/02/08
841 Fixes for UNIX domain sockets. Bug #261.
843 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
845 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
846 Added yaz_marc_subfield_str which defines subfield lead string which is
847 used in YAZ_MARC_LINE format. Default string is blank+$. Added
848 yaz_marc_endline_str which defines end of fields string used in
849 YAZ_MARC_LINE format. Default string is newline.
851 Experimental support for MarcXChange. This format can be produced
852 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
853 http://www.bs.dk/standards/MarcXchange.xsd
855 Added yaz-client commands scansize that sets maximum number of
856 entries to be returned by scan.
858 --- 2.0.32 2005/01/11
860 Added support for SRW scan in yaz-client and Generic Frontend Server.
862 * Added whereInList member to SRW Scan Term.
864 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
866 Fixed NMEM system to return aligned blocks on the smallest boundaries
867 that are suitably aligned for all possible types on the particular
868 architecture YAZ is being built for.
870 --- 2.0.30 2005/01/04
872 Fixed numerious warnings that was issued with newer versions of GCC.
874 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
875 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
878 Make YAZ Generic Frontend Server slightly faster.
880 Enhance (and reduce) logging for Generic Frontend Server.
882 Revert YAZ log system so that it flushes every write operation
883 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
885 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
886 instead of LOG_, due to name clash with syslog(3). LOG_ are still
887 present. New applications should define YAZ_USE_NEW_LOG=1 - this
888 will effectively disable old definitions.
890 --- 2.0.28 2004/11/09
892 Added yaz_log_time_format which specifies log format using
895 Added yaz_log_module_level which returns mask for a module. Value
896 is non-zero mask a if module is enabled; zero if disabled.
898 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
899 in include/yaz/cql.h.
901 Fixed bug #176: Dont throw diagnostics on empty SRU args.
903 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
905 Fixed bug #172: RPM builds does not enable SSL.
907 Doxyfile.in part of dist. Doxyfile generated by configure.
909 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
910 are given and the corresponding component does not exist.
912 Extend CCL documentation in YAZ reference. Describe r=r.
914 --- 2.0.26 2004/10/01
916 Fixed MARC->MARCXML conversion to properly deal with
917 fields, subfields, indicators having non-ASCII characters.
919 Fixed MARC->MARCXML conversion so that ASCII control characters
920 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
923 Added YAZ GFS support for conversion from Z39.50 surrogate
924 diagnostics to SRW surrogate diagnostics.
926 Bug fix: YAZ GFS did not return schema in explainResponse.
928 --- 2.0.25 2004/09/30
930 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
931 now converts recordSchema to elementSetName as well as schema URI.
933 Fixed bug in COMSTACK that prevented HTTP request packages from being
936 --- 2.0.24 2004/09/29
938 Added CCL facility r=r "range" which is similar to r=o "ordered" but
939 does not require white-space before and after the dash in a range, e.g.
940 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
943 Fixed a few AC_TRY_LINK configure tests that did not operate properly
944 due to new GCC removing "redundant" code.
946 Added yaz-client commands scanpos and scanstep that sets preferred
947 position and step-size for scan.
949 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
951 Added CCL utility ccl_qual_buf which parses one or more CCL
952 spec lines in a buffer.
954 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
955 of name and value - ignoring empty lines and comments.
957 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
959 Added odr_get_element_path which returns current element path for an
960 ODR handle. This utility is useful in error handling or user-defined
963 Added ODR_PRINT utility odr_set_stream which is is a more generic
964 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
965 to a write function and pointer to close function. The close function - if
966 non-NULL - will be called during odr_destroy.
968 Fixed bug in CCL parser where truncation char was not removed from
969 right side when truncation=both was in effect.
971 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
974 --- 2.0.23 2004/08/11
976 Fix buffer overrun in CQL parser when dealing with proximity (%).
978 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
979 to UTF-8/UCS conversion is now only based on codetables.xml.
981 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
983 --- 2.0.22 2004/08/06
985 Add support for more "commit changes" in ZOOM (uses Extended Services).
987 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
990 Yet another small fix for configure of SSL.
992 --- 2.0.21 2004/05/14
994 Fix SSL libs for configure when --with-openssl=DIR is given.
996 --- 2.0.20 2004/05/10
998 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1000 SSL comstack now uses yaz.pem certificate file on server side
1001 by default. Certificate filename can be configured by calling
1002 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1004 Fix bug regarding multiple calls to ZOOM_connection_connect.
1006 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1008 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1009 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1011 ZOOM now allows inspection of X509 peer certificate for verification.
1012 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1014 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1015 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1016 as "modular" but it simplifies things.
1018 Added cs_get_peer_certificate to that returns peer X509 PEM.
1020 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1021 NULL if SSL is unavailable.
1023 Documentation about MARC decoding tools.
1025 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1027 --- 2.0.19 2004/03/30
1029 Rename CHANGELOG to NEWS to follow GNU style packing.
1031 Fix bug with missing initialization of member in init_diagnostics.
1032 This bug affects threaded version of GFS server.
1034 --- 2.0.18 2004/03/20
1036 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1039 Ensure zlib.dll is packed with Windows install.
1041 --- 2.0.17 2004/03/17
1043 Fix encoding of xsd:string to use text instead of CDATA.
1045 Fix endless loop in CQL parser with unbalanced ".
1047 Use a more compact way to store MARC-8 conversion tables.
1049 --- 2.0.16 2004/03/16 Debian only
1051 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1054 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1059 --- 2.0.15 2004/03/01
1061 Another fix for decoding of XML packed records.
1063 --- 2.0.14 2004/02/25
1065 Fixes for Chunked encoding. White space not ignored after length spec.
1067 Update NS and use default NS for SRW diagnostic elements.
1069 --- 2.0.13 2004/02/23
1071 Implement ZOOM_resultset_cache_reset which resets record cache.
1073 Implement ZOOM_resultset_sort which sorts a result set.
1075 Implement chunked HTTP transfer.
1077 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1079 --- 2.0.12 2004/02/16
1081 Added member 'schema' to bend_explain_rr structure so that backend
1082 can specify explain record identifier. Defaults to Zeerex 2.0.
1084 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1086 --- 2.0.11 2004/02/16
1088 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1091 Added init command for yaz-client which sends "extra" init request.
1093 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1094 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1096 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1098 Make ZOOM error code for "invalid query".
1100 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1102 --- 2.0.10 2004/02/05
1104 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1107 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1109 Added option -p <file> to make Generic Frontend Server to write PID file.
1111 Added option -D to put Generic Frontend Server in background on its own.
1113 Make ZOOM C recognize option "password". If unset, "pass" is used
1114 (for backwards compatibility).
1116 Fixed a bug in Generic Frontend Server that could make it crash if a
1117 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1120 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1121 Must be issued before open, in order to be in effect.
1123 --- 2.0.9-6 2004/01/12 Debian/Windows
1125 Make the SRU server more picky WRT unknown params, etc.
1127 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1129 New YAZ client command, options, that sets Z39.50 options.
1131 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1132 options from a string of tokens (one token for each option bit).
1134 Update SRW diagnostic code messages.
1136 --- 2.0.9-5 2004/01/07 Debian/Windows
1138 Handle user defined stylesheet for SRW/SRU.
1140 --- 2.0.9-4 2004/01/06 Debian/Windows
1142 Fix bug in decoding of Content-Length.
1144 --- 2.0.9-3 2004/01/06 Debian/Windows
1146 Fix a bug with decoding of XML packed records.
1148 --- 2.0.9-2 2004/01/05 Debian only
1150 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1152 Fix bug in SRW/SRU diagnostics decoding.
1154 --- 2.0.9 2004/01/05
1156 Fixed bug in Generic Frontend Server which could drop records exceeding
1157 preferred message size. Reported and fixed by Irina Dijour.
1159 Fixed calculation of package size for structured records in Generic
1160 Frontend Server. Reported and fixed by Irina Dijour.
1162 Fixed namespace for SRW/SRU diagnostics.
1164 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1166 --- 2.0.8 2003/12/22
1168 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1169 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1172 CQL changes to reflect recent changes to the specification:
1173 * Documentation talks about context sets instead of index sets.
1174 * Documentation talks about indexes instead of qualifiers.
1175 * The CQL-to-PQF transformer's configuration file now uses
1176 "index.set.name = <attributes>" instead of the old form
1177 "qualifier.set.name = <attributes>". (Both forms are still
1178 understood but the latter is deprecated.)
1179 * CQL terms with no explicit index specified are now interpreted as
1180 cql.serverChoice instead of srw.serverChoice (which of course
1181 behaves exactly the same.)
1183 --- 2.0.7 2003/12/16
1185 MARC conversion can now generate ISO2709 output in another
1186 character set. yaz-marcdump uses this facility if you invoke it
1189 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1190 functions from there can be used from C++.
1192 --- 2.0.6 2003/12/04
1194 Frontend server now transfers memory from decoded packages to stream
1197 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1198 references to show up.
1200 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1201 the ZOOM Abstract API. The older names for the same options are still
1202 also supported for the benefit of old applications.
1204 ZOOM-C supports "implementationId" and "implementationVersion" options
1205 to go along with "implementationName". These allow the user code to
1206 specify identification strings to be sent to servers.
1207 Add OID for the new ExtLite attribute set.
1209 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1210 as requested/supplid by Ere Maijala <ere@atp.fi>
1212 For generic frontend server, reverse the order of
1213 "toolkit-supplied / application-supplied" strings sent as implementationId,
1214 Name and Version. Also, remove the spaces around the slash. This brings
1215 the GFS in line with the behaviour of ZOOM-C on the client side.
1217 Add function ZOOM_scanset_display_term.
1219 yaz-client shows scan displayTerm if present.
1221 Utility yaz-iconv is now installed by default along with the man page
1224 Extend configure check for OpenSSL to use pkg-config where available (such
1227 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1228 server to specify uid/gid/mask for socket using the format
1229 unix:[user=uid,][group=gid,][umask=mask,]file=path
1230 If file= is omitted the existing format is assumed, e.g.
1232 in which case the mask is 0666 (rw for everybody).
1234 Major restructure of YAZ source. All source in libyaz is in src directory.
1235 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1236 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1238 Added man page for utility yaz-marcdump (used to be called marcdump).
1239 yaz-marcdump is installed by 'make install'.
1241 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1242 of incoming package failed.
1244 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1246 Change prototype of odr_perror: add const to message string.
1248 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1250 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1251 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1252 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1253 DNS lookup. There should not be any compatibility problems with this
1254 assuming that blocking=1 or 0 is used.
1256 Fix bad reference in UNIX comstack in function cs_addrstr.
1258 Fix for compilation on AIX.
1260 The generic front-end server (server/seshigh.c) now supports returning
1261 Init diagnostics to the client in User-information-field, in
1262 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1265 --- 2.0.4 2003/09/04
1267 Allow any CQL relation (not just all,any,exact,scr).
1269 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1270 that features the same UI.
1272 Implemented command update0 in YAZ client which is equivalent to
1273 update but uses old of Ext Update ASN.1.
1275 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1276 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1277 Previously no OID was used for this info.
1279 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1280 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1281 returns 'malformed search term' otherwise.
1283 SortResponse member resultCount now set to NULL in sort handler of
1286 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1289 Add three new utility functions for translating OIDs between various
1290 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1291 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1292 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1293 char *oid_to_dotstring(const int *oid, char *oidbuf);
1294 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1296 Reverted modifications for ES Update definition for z_IU0Update
1297 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1298 is back to YAZ 2.0.2.
1300 String value attributes for CCL parser.
1302 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1303 which their FirstSearch server returns in Init responses, sometimes
1304 carrying useful diagnostic information when Init fails. This has the
1305 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1306 "z39.50/oclcui.asn", where its definition is somewhat different from
1307 what OCLC document on their web-site, as required to interoperate with
1310 Support for anonymous authentication in yaz-client. Use the command
1313 * Fix the OID of the Index Data-local "admin" Extended Service from
1314 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1315 the 1000, which indicates a locally-defined OID, was a mistake.
1317 --- 2.0.3 2003/06/20
1319 Fix CCL directive @case handling so that it affects string match for
1320 both CCL keywords and qualifiers.
1322 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1323 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1324 Decoder has been updated with ASN.1 changes as listed in
1325 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1326 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1327 z_IUUpdate, remains unchanged.
1329 ZOOM_record_get may now return a record in a specific character set.
1330 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1331 "from" is the character set of record as returned by target. "to" is
1332 the character set to be returned. If omitted, "to" is UTF-8.
1334 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1336 New ODR utility, odr_getelement, which returns name of element for
1337 which encoding/decoding failed.
1339 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1340 in cases where a required element was omitted.
1342 Bug fix: some MARC8 sequences were not converted.
1344 New ZOOM option "step" which specifies number of records to be
1345 retrieved in one chunk. Used in conjunction with "start" and "count".
1347 SRW support for yaz-client. Use scheme http: to use it, e.g.
1350 yaz-client no longer does (un)intelligent character set conversions
1351 by default. Can be enabled with charset and marc_charset commands.
1353 xmalloc trace fix for 64-bit systems such as DEC alpha.
1355 Solaris 2.6 compile fix.
1357 New function, cql_strerror() translates SRW error codes, as returned
1358 by cql_transform_error(), into human-readable English strings. Used
1359 in yaz-client diagnostics when appropriate.
1361 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1362 converts it into a type-1 query which is sent to the server. This
1363 makes CQL available for use with all Z-servers, as opposed to the tiny
1364 minority that can handle CQL queries themselves.
1366 --- 2.0.2 2003/04/28
1368 New Debian package layout similar to the Redhat Package layout.
1370 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1371 and search result respectively.
1373 --- 2.0.1 2003/04/25
1375 Redhat package is now several packages: libyaz (runtime libraries),
1376 libyaz-devel (development and documentation, and yaz (utility programs).
1377 Package spec file by Morten Bøgeskov.
1379 New member 'schema' in struct bend_fetch_rr which the name of requested
1380 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1381 handler MAY set this to reflect the schema of the returned record.
1383 New member 'display_term' in struct scan_entry. GFS now sets member entries
1384 and allocates scan entries to be filled by user scan handler. In previous
1385 version, entries member was allocated by the scan handler. That still works,
1386 but the GFS will ignore member display_term - assuming it was NOT set by
1387 the handler. The fact that the GFS now allocates the entries both allows
1388 for new members and makes a scan handler easier to write.
1390 Fix CQL lex buffer overflow.
1392 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1393 SRU default recordPacking is string.
1395 SRU protocol support for frontend server.
1397 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1399 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1401 Added scan for the ZOOM shell (zoomsh).
1405 * String Identifers for Schemas (Amendment 5).
1406 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1407 Old definition for schema
1408 Odr_oid *schema; /* OPT */
1413 Z_InternationalString *uri;
1414 #define Z_Schema_oid 1
1415 #define Z_Schema_uri 2
1418 * resultCount parameter to Sort Response (Amendment 1).
1419 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1421 Support for SRW 1.0 over HTTP. This is an optional feature and
1422 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1425 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1426 on the same port. SRW SearchRetrieveRequests are mapped
1427 to bend_init,bend_search,bend_fetch,bend_close.
1429 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1431 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1432 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1434 ZOOM connections are SRW based if schem http is used for hostname
1435 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1436 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1438 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1439 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1440 distance=n, order=true/false, relation=le, prox unit=word. If
1441 n is omitted, distance 1 is used.
1443 Fixed problem with C compiler include path in wrong order.
1445 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1446 on Solaris. Patch from Ko van der Sloot.
1448 New MARC decode API. All new functions operate on a yaz_marc_t
1449 handle. The most important new functions are: yaz_marc_create,
1450 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1451 decode and destroy respectively. Decoder can produce formats
1452 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1453 include/yaz/marcdisp.h.
1455 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1456 to UTF-8, UCS-32, wchar_t or Latin-1.
1458 * Prototypes for yaz_iconv_-functions moved to separate header
1459 include/yaz/yaz-iconv.h.
1461 Make a few private functions 'static' in unix.c. This prevents
1462 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1464 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1465 are set when Init Response is received.
1467 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1468 but returns diagnostic set as well.
1470 New function yaz_strerror which is a portable wrapper for
1471 strerror/strerror_r/GetLastMessage.
1473 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1474 is returned for MARC. If type is "oai", then OAI MARC is returned.
1476 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1479 --- 1.9.2 2002/11/26
1481 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1483 Fix bad race conditions on SIGTERM and terminate gracefully in
1486 Move retrieval (data1) module to Zebra since nobody seems to be
1489 Add GRS-1 render for ZOOM using same format as yaz-client.
1491 --- 1.9.1 2002/10/05
1493 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1495 Fix broken ESpec handling in data1 module.
1497 SGML reader parses comments and makes them part of the data1 tree.
1499 Added several type casts so that YAZ compiles as C++ code.
1501 ZOOM didn't handle PDU encoding failures properly.
1503 Added more Bib-1 diagnostics (approved extensions).
1505 GNU configure: better check for iconv.
1507 More portable use of accept, getpeername. Check for socklen_t. Use
1508 int/size_t if socklen_t is not defined.
1512 PQF parser rejects bad queries - including those with extra
1513 characters in them. PQF parser used to silently ignore that.
1514 Cleaner API for PQF added, which allows you to get detailed
1515 error information for bad queries (see yaz/pquery.h).
1517 Fixed bug in ZOOM_record_get for type "database".
1519 Implemented mini iconv library supporting conversions between
1520 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1522 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1524 --- 1.8.9 2002/08/20
1526 Fixed ZOOM C record cache so that preferredRecordSyntax and
1527 elementSetName is used to check for already fetched records.
1529 --- 1.8.8 2002/08/02
1531 Added three members in bend_initrequest structure to facilitate
1532 character set negotiation.
1534 Fixed a bug in frontend server that could cause indefinite
1535 loops under rare conditions.
1537 Revised character set utilities (charneg.h) so that encoding
1538 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1540 For PQF, directive @term <type> sets term type for Scan/Search.
1541 Here <type> is general, string, numeric, null. The term type
1542 is inherited - just like @attr.
1544 New call odr_set_charset that sets character set conversion for
1545 international-strings on a ODR stream. Prototype is:
1546 int odr_set_charset(ODR o, const char *to, const char *from);
1547 The InternationalString is still represented as C string in YAZ
1548 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1549 won't). On the protocol level, you can use any encoding.
1551 Support for UNIX sockets in ZOOM.
1553 Solaris recv sometimes returns errno == ENOENT. It is treated as
1554 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1556 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1557 both client and server. Code by Morten Bøgeskov.
1559 --- 1.8.7 2002/05/22
1561 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1562 that they can be used directly from Visual Basic. You must recompile
1563 your windows APP if you're using ZOOM.
1565 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1566 Commands "lang" and "charset" sets language and character set respectively.
1567 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1568 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1570 Attributes from multiple CCL fields may be OR'ed rather than merged
1571 using directive "@field or". Fields are still merged by default -
1572 equivalent to "@field merge".
1574 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1577 Fixed bug in zget for parameter ExtendedServicesResponse.
1581 --- 1.8.6 2002/03/25
1583 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1585 Client displays USR.1:SearchResult-1 (hits per term).
1587 Additional Search Info for search in Generic Frontend Server.
1589 Fixed CCL parsing of "field=s".
1591 WIN32 installer - using the excellent NSIS software from nullsoft.
1593 Fixed CCL parsing of "field = - <number>".
1595 Added function yaz_marc_decode that decodes MARC for line mode
1596 display or XML (similar to that used by JZKit).
1598 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1599 Z39.50. But ISO/ILL was, however.
1601 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1602 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1604 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1605 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1607 --- 1.8.5 2002/02/03
1609 New YAZ client features: Command completion and new commands:
1610 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1611 Code provided by Jacob Poulsen.
1613 New call oid_trav, that visits all registered OIDs via callback.
1615 Function ZOOM_record_get now returns const char pointer rather than
1616 void pointer. It saves a lot of type casts.
1618 For YAZ client, command "auth" now allows you to set authentication
1619 in IdPass style. It is enabled when three tokens are given - order
1620 is user, group and password.
1622 Fix memory leaks in MARC record handling for ZOOM.
1624 New option for YAZ client, -k <kilobytes> that sets
1625 maximum record size. Similar to -k option for generic frontend
1626 server and yaz-ztest.
1628 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1630 Prefix query parser reports "fail" when bad attribute set is given.
1632 Fix in MARC decoder. Proximity logging. Fix for attribute set
1633 in scan handler for server. Patches by Shigeru Ishida.
1635 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1638 Configure option --with-openssl=<dir> now works when a directory is
1639 specified. Patch provided by Morten Bøgeskov.
1641 New option for YAZ client, -u <auth>, that sets authentication.
1643 ZOOM fix: error information was sometimes "missing", since error
1644 was cleared/reset too when it shouldn't.
1646 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1648 --- 1.8.4 2002/01/04
1650 Scan for ZOOM API. New object ZOOM_scanset. New functions
1651 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1652 ZOOM_scanset_destroy.
1654 New ZOOM function, ZOOM_connection_last_event, that returns type
1655 of last event (such as "receive data", "send data", "apdu received",
1658 New ZOOM option, schema, that specifies schema for retrieval.
1660 New CCL feature. Qualifiers can be aliases for one or more
1661 other qualifiers (if more than one is given, OR is used).
1663 ZOOM uses named result sets if target supports it.
1665 Two new YAZ client commands: . (dot, which sources a script of YAZ
1666 client commands), and ! (to execute shell command.). Implemented
1669 Working on Debian packages.
1671 --- 1.8.3 2001/11/19
1673 YAZ client enables named result sets only if target supports it.
1675 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1677 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1678 with key="host" to get same result.
1680 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1681 Function Z3950_resultset_record(s) returns references to records
1682 "owned" by resultset. To become owner use Z3950_record_clone.
1684 Function z_ext_record handles Extended Services. Thanks to
1687 --- 1.8.2 2001/11/12
1689 CCL Parser fix: ignore token comma when dealing with and-lists.
1691 Documentation updates for COMSTACK.
1693 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1694 Changed prototype Z3950_records. For some functions, int parameters
1695 were changed to size_t.
1697 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1700 New MARC decode/display function, marc_display_exl, which properly rejects
1701 non-ISO2709 records. YAZ client uses it.
1703 --- 1.8.1 2001/10/29
1705 Fix bug: local attribute set wasn't set correctly in PQF strings.
1709 * Old Z39.50 codecs no longer supported.
1711 Added ZOOM C binding. See http://zoom.z3950.org/
1713 Renamed states for COMSTACKs to avoid confusion with events.
1715 Implemented cs_look and proper cs_rcvconnect.
1717 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1719 Configure detects POSIX threads on OpenBSD.
1721 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1722 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1724 When error is returned from present handler, non-surrogate diagnostic
1725 is returned in present response (and fetch handler is no longer called).
1727 * Minor adjustments to pquery parser (PQF). Token characters may be
1728 escaped by using backslash (C-style).
1730 PQF parser allows string attribute values to be specified. For @attr,
1731 non-numeric characters after the equal-sign are treated as strings
1732 (e.g. @attr 9=title).
1734 CCL trunction character may be defined (@truncation in file)
1736 * function zget_ExtendedServicesRequest sets waitAction to
1737 waitIfPossible (was wait).
1739 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1742 CCL operator names may be set in field definition files (CCL_bibset).
1743 See ccl/bib1 for an example.
1745 Fixes in ASN.1 compiler for C++ compatibility.
1747 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1748 and "op_or" to avoid conflict with C++.
1750 Fixed problem with GNU readline detection on Redhat 7.0.
1752 Added step-size for Scan backend handler.
1754 Fixed bug that made the frontend server crash when no attribute
1755 set was specified for scan.
1757 Front-end server automatically switches to original working directory
1758 when installed as an NT service. Previously -w had to be specified to
1761 Added extended attributes for retrieval module (data1), so that data1
1762 records carry d1_readXML/SGML attributes. d1_read also supports
1763 null-data rules ( <tag/>)
1765 On UNIX when POSIX threads are available, a separate library libyazthread
1766 is created. Programmers should link with that library and the yaz library
1767 when using threads. The reason for the split was that some applications
1768 on Linux, such as Apache, doesn't work well when using shared objects that
1771 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1772 (or any frontend server) in SSL mode by specifying ssl: followed by
1773 address. Only tested on UNIX.
1775 Added feature for CCL module. Virtual structure s=al or s=ol generates
1776 and-list and or-list respectively instead of phrase search.
1780 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1781 log_mask_str. This was done to avoid name conflicts with other libraries
1782 (such as other PHP extensions).
1784 Added raw OID member for preferred record syntax (request_format_raw)
1785 and returned record syntax (output_format_raw) for backend fetch method.
1787 Config file yaz-config now accepts options so that it returns specific
1788 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1790 Shared library support for UNIX using GNU libtool.
1792 * Modified backend interface. Request/Response struct's replaced by
1793 one read/write C struct. For example bend_fetchrequest and
1794 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1795 Every handler - even search has to be registered in bend_init
1796 handler. This means that the YAZ library no longer refers to
1797 external functions and it makes it possible to make the whole
1798 thing a single DLL/SO.
1800 Added Segment handler for backend server.
1802 Added Zmbol/Zebra administrative functions to YAZ client.
1804 Threaded frontend server on UNIX (when POSIX Threads are available).
1805 Starting the server with option -T enables multi-threading.
1809 Added configure option --enable-comp/disable-comp to control use
1810 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1811 located in sub directory asn.
1813 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1814 in ${exec_prefix}/bin along with the other programs yaz-client and
1817 GNU automake used to maintain makefiles.
1819 Added several OID's.
1821 Changed retrieval module so that we can load records with no abstract
1822 syntax defined. Tagpaths in these records are fully composed of string
1825 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1829 On UNIX, the generated makefile now supports a proper 'make install'.
1830 The prefix can be set via GNU configure to set the install location
1831 (default is /usr/local).
1833 * YAZ programs client and ztest were renamed to yaz-client and
1834 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1835 locations, such as /usr/bin,/usr/local/bin,etc.
1837 * YAZ Header files were moved from include to include/yaz. YAZ Header
1838 files are referred to as include <yaz/log.h> rather than <log.h>.
1839 The YAZ include path (-I ..) is therefore the same as before. Programmers
1840 should update their #include statements or use -Ipath/include/yaz
1841 instead. The main motivation for doing this change is that YAZ header files
1842 can be installed in "standard" locations /usr/include,/usr/local/include
1843 without introducing conflicts, since ALL YAZ header files are stored
1844 in subdirectory yaz (under /usr/include for example).
1846 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1847 rather than project/workspace files. We switched because project files
1848 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1851 Changed name of logging function, logf, to yaz_log, to prevent name
1852 clash with some math-log functions. The YAZ header log.h defines logf
1853 to yaz_log (#define) so there should be no incompatibilities by this
1856 Added bend_start/bend_stop handlers for server. These handler are
1857 called on start/stop of server. For windows they are called whenever
1858 a service is started/stopped.
1860 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1861 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1862 in util/yc.tcl. The auto-generated C code structures are, in a few
1863 cases, incompatible with the old decoders. There are differences in the
1864 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1865 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1866 The preprocessor variable ASN_COMPILED is defined when the compiled
1867 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1868 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1869 wish to use the old encoders/decoders you can specify --disable-yc
1872 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1873 version so that it supports both new - and old version of DB Update
1875 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1876 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1877 change. The name parameter can be set to 0 in which no name is specified
1878 for the construction. The macros odr_implicit and odr_explicit sets name
1879 parameter to zero for the construction involved. New macros
1880 odr_implicit_tag and odr_explicit_tag are similar to the others,
1881 except that a name parameter is added. For programmers' that don't use
1882 ODR they probably only need to change the call to z_APDU and z_External.
1884 Added access control facility by interfacing the TCP wrapper library.
1885 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1886 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1887 name of the daemon and enables the access control as specified in
1888 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1890 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1891 den Dool <H.M.vdnDool@kub.nl>.
1893 Added reference ID parameter to most functions in server API - refer
1894 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1896 Changed name of ccl library to libccl.a (was ccl.a).
1898 Fixed bug in decoder for Explain (Category TargetInfo).
1900 Added support for GNU readline in client. Thanks to Jacob Poulsen
1901 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1903 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1904 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1905 IMPLEMENTATION! This change was made to the development version before
1906 the ZIG decided to retract the amendment. If any users MUST be
1907 compatible with the original Update definition, PLEASE CONTACT US, and
1908 we will include a separate definition corresponding to the old Update
1909 ES. Note that because of the change to the ASN.1 of the
1910 TaskPackageRecordStructure we cannot define a single structure that
1911 will support both versions.
1913 * Added const modifier to buffer parameter for some ODR/BER encoding
1914 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1915 completeWAIS, odr_dumpBER.
1917 Fixed bug in client.c which caused a crash when a scanResponse didn't
1918 contain positionOfTerm.
1920 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1921 * will cause an error in a client if a non-YAZ target sends both a
1922 * list of Scan entries and non-surrogate diagnostics.
1924 Retrieval module enhancements. Tag sets may be typed in the reference
1925 to it. From the .abs-file the "tagset" directive takes a third optional
1926 integer type for the tag set referenced. From a .tag-file the "include"
1927 directive takes a third optional type as well. The old "type" directive
1928 in the tag set itself is still recognized but acts as the default type
1931 Backend interface change. Individual Scan terms returned from bend_scan
1932 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1933 in include/backend.h.
1935 Retrieval module enhancements. Multiple tag sets and attribute sets may
1936 be specified in abstract syntax specs. Revised the error/warning for
1937 logging messages reported by the retrieval module when reading the
1940 Object Identifier system (oid_..) changed. The API is backwards
1941 compatible but the oid-routines now allocates new OID's when needed.
1942 Raw OID's may be specified in oid_getvalbyname.
1944 YAZ now uses GNU configure to generate Makefile(s).
1946 * Minor changes in some of the member names of DeleteResultSetRequest and
1947 DeleteResultSetResponse. See include/proto.h.
1949 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1950 and added member 'languages' in TargetInfo (which was missing).
1952 Changed the way attribute sets are handled in the retrieval
1953 module. These are now cached, just like the abstract syntaxes
1956 Changed YAZ so that it links with compiled ASN.1.
1958 Added Explain-schema definitions and mapping routines. The following
1959 Explain categories have been implemented: AttributeDetails,
1960 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1962 Fixed minor bug in Windows version of Server Library.
1964 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1966 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1968 Added EXTERNAL: UNIverse Resource Report (non-standard).
1970 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1971 ENUMERATED and SET OF.
1973 * Added 'const' to some of the char pointer arguments for the
1974 functions, data1_read_node, data1_getelementbytagname,
1975 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1978 Fixed bug in data1_insert_taggeddata - the last_child member of
1979 parent wasn't initialised.
1981 * Changed data1_read_record and data1_read_node so that the supplied
1982 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1983 doesn't refer to any parts of the "SGML"-buffer.
1985 Fixed bug in server library (Windows version of statserv_remove).
1987 * Changed code so that it compiles as C++. The type definition
1988 of Odr_fun which is a member of Odr_arm was changed. The result is,
1989 that an explicit typecast is needed for the fun pointer when
1990 using Odr_arm - as in:
1991 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1993 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1995 Implemented the new structured date and time definition as approved
1996 by the ZIG. Added schemaId element to the specificTag in Espec-1
1997 (also approved at the last ZIG). Thanks to RVDM.
1999 Added some Object identifiers (RVDM).
2001 Changed the Update Extended Service (RVDM).
2003 Added command "refid" to client which specifies referenceId for
2004 the following requests.
2006 Implemented extended service handling for server. See ztest.c
2007 for an example as well as backend.h. New handlers are registerd
2008 in the Init handler.
2010 * Changed interface for sort in server.
2012 Added new members to statserv_options_block. It allows a server
2013 to read options from another source than just the command line. Thanks
2014 to Charles Woodfield.
2016 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2017 renamed to zboolean. Some C++ compilers complained about the name.
2019 Minor changes to gils.abs. Added index 's' (sort) on title
2020 and date/time-last-modified.
2022 --- 1.4pl2 1998/1/30
2024 Fixed bug in server library regarding inetd mode (-i). This bug
2025 was introduced by release 1.4.
2027 --- 1.4pl1 1998/1/29
2029 Added sort facility in client and backend server interface.
2031 Fixed problem with dependencies in Makefile(s).
2033 Fixed bugs for encoders/decoders of extended services and
2036 Implemented sub-tree feature for schemas. Sub-trees are
2037 referenced in *.abs-files. See explain.abs for an example
2038 of the use of this feature.
2040 Modified bib1.att; local attributes for ANY didn't include
2041 ANY itself (only affects use of the retrieval module).
2043 Fixed bug in plain SGML reader in function data1_read_node:
2044 tags with prefix "var" was incorrectly interpreted as variants.
2046 Added feature "sub-schemas" to enable references to - and definitions
2047 of - group of elements.
2049 * Removed member parent from type data1_element (in data1.h).
2051 Implemented function odr_nullval() that returns the value of
2054 * Removed member num_children from data1_node (in data1.h).
2056 Made NT service interface part of the server library. The
2057 function statserv_main uses the NT service when required and
2058 calls the statserv_start / statserv_close routines.
2060 Routine zget_SearchRequest and zget_PresentRequest fills
2061 resultSetName/Id member with "default" instead of "Default".
2063 Fixed memory leak in server. Request queue member wasn't freed.
2065 Fixed nmem_exit so that memory is freed.
2069 Revised the CCL parser utility to be thread safe.
2071 Added function, oid_ent_to_oid, to replace the function
2072 oid_getoidbyent, which is not thread safe.
2074 * Added nmem_init and nmem_exit to initialize and release
2075 NMEM resources. Function nmem_init should be called once in the
2076 initial thread before NMEM/ODR is used. statserv.c and client.c
2077 have been changed accordingly. The change was necessary to make
2078 NMEM thread safe. The NMEM memory pool is shared amongst threads
2079 in a process. Unix-based applications will still work fine without
2082 Added NT Services interface for the the Z39.50 (statserv) Server.
2083 Refer to the ztest.c source on the usage.
2085 Windows 95/NT port using MSVC5.0. Project files are included in the
2088 * Defined new 'global' handle for the retrieval (data1) system. The
2089 new handled, data1_handle, describes the state of the data1 system.
2090 This handle is passed as first argument to virtually all
2091 data1 related routines. The functions data1_create and data1_destroy
2092 creates and destroys a data1 handle respectively.
2094 Added ODR encode stream member to all backend request structures
2095 init, search, scan etc. This stream should be used to allocate all
2096 memory used for the response when thread safe operation is needed.
2098 Changed the comstack utility, cs_addstr, to be thread safe. The
2099 returned hostname string returned by the function is now part the
2102 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2103 function. The cs_straddr takes a COMSTACK handle as argument, so this
2104 function must be used after cs_create and before bind/connect.
2105 This function is thread safe.
2107 Moved test server to 'ztest' directory - generic server code still
2108 in 'server' directory.
2110 Made prefix query (pquery.c) utility thread safe.
2112 Added new function modifier YAZ_EXPORT to 'export' public DLL
2113 functions when using windows (see include/yconfig.h).
2115 Added definitions to the OID database (util/oid.c) (RVDM).
2117 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2119 Added call to ccl_rpn_delete in client program.
2121 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2122 release of RPN structure.
2124 Added support for C++, headers uses extern "C" for public definitions.
2125 With input from RVDM.
2127 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2128 Thanks to Ronald van der Meer (RVDM).
2130 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2132 Added support for private extensions to the OID database
2133 (oid_setprivateoids()). Thanks to RVDM.
2135 Added optional, physical ANY (key replication)
2137 Fixed null-reference problem in GRS-1 output filter.
2139 Proximity operator added to Prefix Query Format (PQF).
2141 In test client command "base" accepts multiple databases.
2143 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2147 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2149 Smallish bug-fixes in the new encoders/decoders (explain).
2151 Bug fixed in DeleteRequest.
2153 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2155 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2157 Added SOIF syntax (using private OID for now) to retrieval module and client.
2159 Added Update extended service.
2161 Added SearchResult-1 additional info structure.
2163 Added optional CCL (ISO8777) interpreter as separate module. Available
2166 --- 1.2 1996/6/10 (1st anniversary release)
2168 Added Summary record syntax. Lightly tested.
2170 Added OPAC record syntax. Untested.
2172 Added ResourceReport service encoders/decoders. Untested.
2174 Fixed bug in z_Unit - wrong tagging on unitSystem.
2176 Fixed bug in the DiagRecs decoder.
2178 Added options for max PDU size and session timeout to frontend-server.
2180 Added documentation of query-language parsers and other supporting utilities.
2182 [frontend-server] Added Attribute set to the bend_scanrequest API.
2184 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2185 surrogate diagnostics were generated.
2187 [retrieval] Allow multiple local values for attribute.
2189 [retrieval] Allow multiple attributes per element in .abs files. index type.
2191 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2193 --- 1.1pl2 1996/4/10
2195 Minor changes, mostly specific to Zebra's requirements (retrieval)
2199 Repaired bug in frontend server when running multiple listening
2200 endpoints in dynamic mode.
2202 z_External() now won't break if a known, ASN.1 value comes encapsulated
2203 in an octet-string. The value will pass through unmodified in an Odr_oct.
2205 Added a bit of code to the demo client to decode & display
2206 ASN.1-structured records represented in the octet-aligned branch of
2207 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2209 Added z_ext_getentbyref() to the ASN module. Doc updated.
2211 * Completed the SCAN definition in the ASN module. This may break SCAN
2212 code based on older YAZ-versions at compile-time. The fix is easy -
2215 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2216 under the SCAN definition. Remember to initialize this, server-people.
2218 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2219 that this does not extend to ODR and ASN.
2221 Comstack allows insertion of established socket (primarily for
2222 inetd-operation of servers). Doc updated.
2224 Front-end server can now start from the inetd in TCP mode. Doc
2227 --- 1.0pl4 1996/1/24
2231 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2232 the rank and record number.
2234 Adjustments to the frontend server.
2236 Fixed diagnostic BER dumper. It ignored the file argument.
2240 Various changes to retrieval module.
2242 Changed the union discriminators of the protocol files from enums to
2243 ints paired with #defines.
2245 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2248 *Changed operator in the RPN structure to 'roperator', again to avoid a
2251 Fixed problems in Explain decoders/encoders.
2253 --- 1.0pl2 1995/12/6
2255 Memory bug in log module fixed.
2257 --- 1.0pl1 1995/12/5
2259 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2261 Bug in Explain DatabaseInfo module fixed.
2263 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2267 The shift to v1.0 signals that we now consider the *core* functionality
2268 of YAZ reasonably stable (the core being more or less equivalent to
2269 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2270 tested (Explain not at all - though that will happen soonish).
2272 Minor changes to code to support Windows port.
2274 Various minor changes after we're getting to use GRS-1 & co. more.
2276 Added Espec-1 format.
2278 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2279 of the protocol and it cannot be selected when encoding (maps into 'string'
2280 when decoding). Needed to talk to some servers.
2282 Demo client can request simple element set names.
2284 Added Diagnostic Format encoders/decoders.
2286 Added simple Close handling to frontend server (no hooks for resource
2287 reporting yet), and demonstration client.
2289 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2291 --- 1.0b3 1995/08/24
2293 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2294 handled incorrectly when records were requested in the searchResponse. This
2295 will only affect you if you use the frontend-server.
2297 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2298 Test-client will ask for and print GRS1. Ztest will return dummy records
2301 Added Explain encoders/decoders to the service-level API. Untested.
2303 Added Extended Services: Item Order encoders and decoders to the Service-
2304 level API. Untested. We could use a recent copy of the pertinent bits
2305 of the ILL protocol to add those bits.
2307 Added diagnostic format 1 encoders/decoders to the service-level API.
2310 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2311 odr_cons.c, which causes a more correct output.
2313 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2314 was always set to 0 when no records were requested in the searchRequest.
2316 * Added better external-handling. This shouldn't harm old code that
2317 *encodes* externals. It can break code that looks for a
2318 'single-ASN1-type' representation, since those types that are known
2319 are now decoded immediately. Look at the SUTRS sample code in
2320 seshigh.c and client.c. Documentation updated.
2322 Handling of structured records in bend_fetchresponse. Length -1 marks
2323 structured record, type is deduced from format field.
2325 --- 1.0b2 1995/06/27
2326 Fairly quick maintenance release to add SUTRS support.
2328 Fixed handling of SUTRS records in the demonstration client.
2330 * Added format field to the bend_fetchrequest and bend_fetchresponce
2331 structures of the backend API (frontend server). When the record is
2332 returned, the value of the format field is mapped to an OID. The
2333 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2334 of the record. The special value VAL_NONE in the bend_request means
2335 that no specific format was requested by the client. Documentation
2336 updated accordingly. Test server (ztest) will return a fixed dummy
2337 SUTRS record if your client requests SUTRS.
2339 Documentation updated accordingly.
2341 You can now set external libraries and RANLIB support in the top-level
2345 First public release.
