1 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
5 Document --with-xml2 option.
7 Added OPAC XML XSD (etc/opacxml.xsd).
9 Allow glob mask for name attribute in retrieval element for the
10 generic frontend server's retrieval facility.
12 Changed yaz_poll_poll to return yaz_poll_except for all returned events
13 except POLLIN/POLLOUT.
15 Fixed error handling in cs_listen. Bug #2037.
19 Fixed version in yaz/yaz-version.h.
21 Fixed bug #2027: Crash when closing connection.
23 Changed configure so that ICU support is only enabled if only ICU
24 and Libxml2 is available (because the ICU chain is XML based).
28 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
29 is built. Only this DLL depends on the ICU runtime.
31 yaz-ziffy is no longer part of YAZ. It is distributed separately by
32 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
34 Changed license of CCL module to 'Revised BSD'. After consultation with
35 remaining members of the original EUROPAGATE consortium, we are re-issuing
36 the CCL module without a separate license. The software was developed by
37 Index Data as part of a research project. The special license was included
38 to help feed usage information back to the project consortium to support
39 project evaluation. At this time, the project consortium has long-since
40 disbanded, and the majority of the original principals have retired. At the
41 same time, we have significantly modified the software during the following
42 years, to the point where very practically no original code remains. To
43 simplify re-use of the software, we have contacted those members of the
44 consortium who could be reached, and agreed to re-issue the module as a
45 proper part of the YAZ package.
47 Tcl scripts uses /usr/bin/tclsh as preferred shell.
49 CQL closer to being version 1.2 compliant. CQL also allows free-form
50 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
53 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
54 bug could make Extended services handling crash in the ZOOM layer. This
55 bug was only present in YAZ 3.0.18.
59 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
62 yaz-marcdump reads and writes collection wrapped records.
64 Handle OPAC for record conversion module.
66 Fixes for ICU wrapper.
68 Allow ICU libs to be controlled with --with-icu .
72 Added yaz_poll which is a wrapper for select/poll. When poll is available
73 and non-buggy, it is used, by yaz_poll . This allows more than 1024
76 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
77 functionality through an XML based configuration (ICU chain). This system
78 is useful for search facilities such as Pazpar2 and Zebra that needs to
79 perform tokenization of indexed material. The ICU code in a separate
80 library libyaz3_icu.a.
82 Added HTTP tunnel facility for COMSTACK, bug #1752.
83 This is a facility that allows a Web proxy, such as squid, to tunnel
84 Z39.50 traffic. This facility is "transparent" to must applications
85 using YAZ. It's enabled by using pseudo transport connect: followed by
86 the proxy address, followed by command, then follwed by he regular
87 "virtual" addresss. For example,
88 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
90 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
94 Fixed bad memory reference in ZOOM_record - cuased by member not being
95 initialized. This was a problem only in YAZ 3.0.12.
97 Fixed bug in conversion from MARC to XML: Non-XML characters in control
98 fields were not removed.
100 Changed the way C code is generated from codetables.xml. Made a MARC-8
101 conversion trie for each characterSet section rather than codeTable.
102 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
103 of codetables.xml from Larry Dixson, LOC. Bug #1464.
105 --- 3.0.12 2007/09/12
107 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
108 from ZOOM_record_error).
110 ZOOM C function ZOOM_record_get returns record schema for type="schema".
112 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
114 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
116 Better SRW-to-Bib-1 diagnostic mapping.
118 ZOOM C and yaz-client announces SRU version 1.2 by default.
120 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
123 Fixed in yaz_sru_decode to allow other version than 1.1.
125 --- 3.0.10 2007/08/22
127 Added support for SRU scan for ZOOM.
129 Added support for the use of the older versions or Extended Service
130 Update in ZOOM. To faciliate this, an option "updateVersion" may be
131 set to the version , 1=first, 2=second, 3=third. The third version is
132 what ZOOM C has used so far. And that, obviously, is the default.
134 Added support for CCL queries in Z39.50 queries sent to the GFS (and
135 therefore in Zebra and in SimpleServer-based applications). The new
136 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
137 qualifier file used to transform incoming CCL queries into Type-1 RPN,
138 which is passed into the back-end search callback function.
140 Added support for HTTP Basic authentication in clients: the SRU/W
141 codec encodes the username/password elements of the PDU structure
142 appropriately, and these may be set using the "user" and "password"
143 options in ZOOM-C applications (the same options that are used for
144 Z39.50 authentication).
148 Fixed bug #1208: SSL appears to be broken in ZOOM.
150 Fixed bug #1206: Libxml2 include path weirdness.
152 Added oid_name_to_dotstring.
154 Allow elementSetName to be specified for ZOOM C record update.
156 Allow waitAction to be specified for ZOOM C based for Extended Services.
158 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
159 syntax OID. Bug introduced in YAZ 3 series.
161 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
165 Fixed bug #1157: yaz-client does not read .yazclientrc from current
166 directory. yaz-client now reads commands from file given by option -f
167 if specified; then tries to read .yazclientrc in current directory.
168 Failing that, it reads .yazclientrc from user's home directory.
170 Added support for correlationInfo Note and ID for Record Update via
173 Added yaz-client command querycharset which specifies character set for
174 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
175 (termListAndStartPoint).
177 Charset ISO5428:1984 is an alias for ISO5428-1984.
179 Implemented a way to perform scan in a result set using Z39.50. This
180 is achieved by attaching the result set name in the characterInfo
181 (type InternationalString) of OtherInformation in the Scan Request PDU.
182 The result set is identified in the otherinformation by the new OID:
183 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
184 This allows for scan in result set and faceted search . Zebra did some
185 of this in the APT term using attribute type 8 and value being result
186 set. Using the OtherInformation approach for this is cleaner and easier
187 to work with in proxies and the like. This facility can be used in
188 yaz-client using new command setscan which takes a result set as first
189 argument, start position (APT) as second.
191 Changed decoding of SRU XML packed records to deal with servers that
192 have recordData with XML data with multiple root nodes. Also make
193 comparison for recordPacking case insensitive. Again, one server
194 returns "XML" where others return "xml".
196 For SRU responses allow Content-Type application/xml as well as text/xml.
200 Fixed bug in character set conversion of BER strings. Bug introduced
205 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
207 For OID class, use oid_class consistently.
209 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
212 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
213 character set for bibliographic information interchange". By Giannis Kosmas.
215 Added documentation on new OID API.
219 Changes to generic frontend server interface: added new member
220 'query_charset' for bend_initrequest structure. A backend init handler
221 should set this member to its native character set for query terms.
222 When defined, the frontend server logic will announce this character set
223 to a client if the negotiationModel bit is set by the client. All server
224 implementors are encouraged to specify this. If a backend server does not
225 specify this a warning is issued using yaz_log(YLOG_WARN,..).
227 Added CCL utility to remove terms (stop words) from resulting RPN
228 tree. This is handled by functions with prefix ccl_stop_words_ .
230 New ZOOM C option, "rpnCharset", which allows client-side conversion of
231 terms in RPN queries.
233 Clean-up the CCL API. Moved some internal structures from ccl.h to
234 private header cclp.h. Changed ccl_parser_create so that a Bibset must
235 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
236 This is replaced by ccl_parser_find_str which takes a string instead.
238 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
239 libyaz.la is the core of YAZ except the generic frontend server and
240 does not depend on POSIX threads anymore. libyaz_server.la is the
241 generic frontend server facilities and uses POSIX thread functionality
242 if available. The libyaz.la no longer depends on POSIX threads because
243 the number of global structures is limited. NMEM no longer re-uses blocks
244 between threads ; it simply free's memory immediately but allocates in
245 "large" chunks as usual. We don't expect any performance penalties
246 because of this. The yaz_log system is still using a global log_level so
247 caution must be taken when modifying it with yaz_log_init_.. +
248 yaz_log_mask_str. This, however, should not cause any trouble because
249 these functions are called during initialization of application code
250 anyway. `yaz-config --libs server` returns libs for server applications;
251 `yaz-config --libs` returns libs for non-server applications.
253 New OID database - with public definitions in oid_db.h. Removed old OID
254 database including the head oid.h and definitions such as enum oid_value
255 and struct oident. The new OID database uses the same string names as
256 before but the 'protocol' is gone. There are now only two representations
257 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
258 converts from string to OID; functions with prefix yaz_oid_to_string
259 converts the other way.
261 Change to emit_term() in CQL-to-PQF query translation: when a term has
262 the /regexp relation modifier, do not process it for leading and
263 trailing "^" and "*", which have quite different meanings in regular
266 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
267 write handlers no longer carries a 'last' parameter. This will make
268 yaz_iconv flush "less" characters. A flush is performed by call to
269 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
271 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
272 removed, because function yaz_query_to_wrbuf does the same.
274 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
275 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
277 Deprecated MARC utility functions removed.
279 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
282 Branch split: YAZ_2_1_55_branch
284 --- 2.1.54 2007/03/16
286 Fix to ZOOM-C so that transparent reconnection is properly handled on
287 connections that are in asynchronous mode.
289 Fixed compilation on OpenBSD 4.0.
291 Large strings in GRS-1 records are now properly displayed in yaz-client.
293 Added character conversion support for "advancegreek"; based on patch from
296 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
297 sequence is met. Before the error was not set so it would be unknown.
299 Adjust yaz-marcdump MARC reader so that it skips until record separator
302 --- 2.1.52 2007/03/07
304 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
305 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
306 fd_set structure used as a bitmask for the FDs to be selected on.
308 Using ACX_PTHREAD macro to check for POSIX threads.
310 Fixed have-vsnprintf check.
312 --- 2.1.50 2007/02/23
314 Fixes for configure on BSD. Bug #900.
316 Added snprintf/vsnprintf wrappers for systems that don't have
317 limits (heavens forbid).
319 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
320 created before all previous tasks were completed and removed from the
321 task queue, the new task could be removed by a mistake.
323 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
325 Implemented pass-through CQL-to-PQF conversions. Bug #861.
327 Fixed bug #832: Problem with MARC/charset in yaz-client.
329 Fixed bug #668: save command line history for yaz-client.
331 Fixed bug #830: pkg-config support.
333 --- 2.1.48 2007/01/23
335 Extended ZOOM result set options with two options that may be read by
336 a client: resultSetStatus and presentStatus with values as specified for
338 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
340 Fixed bug #827: Using SSL fails on Debian etch.
342 Fixed bug #826: Weird looking chars for set of MARC records.
344 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
345 that is treated as an ItemOrder with itemRequest being an XML document
346 external. The value of "doc" is the content.
348 Extended the GFS search facility. New member of bend_search_rr
349 'estimated_hit_count' signals that hits is known to be an estmate
350 (higher or lower than real hit count). New member 'partial_resultset'
351 signals that the search was partial (hit count is lower or equal than
352 real hit count). For Z39.50, the information is stored in resultSetStatus
353 member of SearchResponse APDU. For SRU, the information is signalled
354 via SRU diagnostic 59: "Result set created with valid partial results
357 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
359 --- 2.1.46 2007/01/13
361 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
363 Added ZOOM_connection_peek_event.
365 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
366 the following new functions:
367 ZOOM_event_nonblock, ZOOM_connection_process,
368 ZOOM_connection_get_{socket,mask,timeout},
369 ZOOM_connection_fire_event_{timeout,socket}.
370 The existing blocking event handler, ZOOM_event, is a wrapper for the
371 + blocking ZOOM_event_sys_{poll,select}.
373 Implemented function ccl_xml_config which parses XML version of CCL
374 configuration (bug #798).
376 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
378 Added timings utility (yaz/timing.h)
380 --- 2.1.44 2007/01/03
382 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
385 Fixed bug #779: Rotation of apdu.log fails.
387 Fixed for character set conversions:
388 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
389 Honor G1 set in MARC-8 decoding.
391 --- 2.1.42 2006/12/17
393 Fixed bug #775: char conversion does not handle Alternative UTF-8
396 Implemented function yaz_marc_read_line which parses MARC line format
397 records. There is a wealth of formats out there. So far, this function
398 reads line records produced by yaz_marc_write_line.
400 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
401 more generic and easier to remember(!) options: -i format and -o format
402 which specifies input format and output format respectively - where
403 format is one of "marc", "marcxml", "line", "marcxchange".
405 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
406 does not print anything except warnings for records.
408 For yaz-marcdump, added support for MARC split into files (-s) with a given
411 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
412 spec, at http://www.loc.gov/standards/sru/record-update/
413 This has changed the binary layout of the following structs:
414 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
415 bend_update_rr . Patch by Ko van der Sloot.
417 Added GFS utility function bend_assoc_is_alive which returns 1 if
418 association is still alive (client is connected); 0 otherwise (client
419 closed connection). This allows busy servers to stop working for
422 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
423 been a separate piece of software. This version of ziffy has been modified
424 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
426 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
428 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
429 Client code may now interrogate options such as "init_opt_sort" to
430 find out whether the server claims to support various options.
432 --- 2.1.40 2006/11/27
434 Added utilities yaz_{set,get}_esn to set/get element set name from
437 Removed the build of libyazthread.la. The libyaz.so is the threaded version
438 of YAZ and has been so since YAZ 2.1.10.
440 Implemented ZOOM_record_error which returns error information for
441 record (surrogate diagnostic).
443 --- 2.1.38 2006/10/31
445 Updates for SRU Update by Ko van der Sloot:
446 1. Changed name from "operation" to "action"
447 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
448 versions in the code, marked as 'backward compatible'.
449 3. Added diagnostics for SRU Update.
451 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
453 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
455 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
457 For GFS, fixed problem with SRU diagnostic 'First record position out of
458 range' being issued for 0 hits.
460 zoomtst10 part of Windows Build.
462 --- 2.1.36 2006/10/13
464 Implemented yaz_filepath_comp which splits a path into file path
465 components (required by Zebra 2.0.3+).
467 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
468 BSD inspired license until now so this should not have any real impact on
469 anybody. See http://www.opensource.org/licenses/bsd-license.php
471 Fixed bug #687: Missing log lines.
473 Fixed bug #678: CQL to PQF translation does not preserve double-quote
476 Fixed bug #689: SRU diagnostics to be added.
478 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
479 whether a connection is idle (no more work do do).
481 --- 2.1.34 2006/10/04
483 Change type of optval from long to int for invocation of setsockopt with
484 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
486 Added support for specifying the max log file size for the Generic
487 Frontend Server. The size is given with option -r.
489 --- 2.1.32 2006/09/21
491 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
493 --- 2.1.30 2006/09/17
495 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
498 Fixed bug in Generic Frontend Server that could cause a server to stop
499 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
501 For the generic frontend server, the maximum record size is used as maximum
502 size of incoming packages (SRU + Z39.50). The value until was previously
503 only used in Z39.50 Init negotiation and, later, in a session controlled
504 sizes of records returned. This is controlled using -k option. It can be
505 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
507 --- 2.1.28 2006/09/04
509 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
512 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
514 New option for yaz-marcdump -lpos=value which allows setting a portion
515 of MARC header to a certain value.
517 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
519 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
520 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
522 --- 2.1.26 2006/08/15
524 Fixed problem with SRU mode type (soap, get, post) for yaz-client
527 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
529 --- 2.1.24 2006/08/08
531 Fixed MARC ISO2709 encoding routines to deal with character set
534 Minor changes to GFS logging. Database included in search request log
537 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
538 cached/multiple records.
540 Shared libraries are built by default on Unix+configure.
542 Changed cql2pqf transformation to use a different evaluation order. The
543 new order is: always, relation, structure, position, truncation, index
544 and relationModifier. Old order was: always, relation, relationModifier,
545 structure, index, position, truncation. Note that the the latter ones
546 override former ones for identical attributes.. The new scheme means that
547 it is possible to override any existing attribute with a relationModifier.
548 And also that it is possible to override everything for the index rule
549 (except the ones listed in relationModifier). No order is perfect but this
550 one, we believe, covers more real cases.. The "always" should have been
551 called "default", since the attributes there can be overridden with all
554 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
555 compilation phase, but also for yaz-config --cflags output. This allows
556 us to have public headers with Libxml2 stuff in them . It should also,
557 eventually, make Libxml2 checks redundant in packages using YAZ, such
560 --- 2.1.22 2006/06/15
562 Changed SRU update structure bend_update_rr so that SRU diagnostics are
563 stored in uri, message and details.. Previously diagnostics were stored
564 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
565 compatibility.. but he's probably the only one affected, so.
567 Added support for CCL, compiled on the client side, in ZOOM-C. This
568 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
569 input; the resulting query objects can be used for for searching with
570 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
572 YAZ' configure searches for OpenSSL by default.
574 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
575 SL_CTX_use_certificate_file. See
576 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
577 for more info. Thanks to Ko van der Sloot.
579 --- 2.1.20 2006/06/02
581 Bug #600: SRU GET, POST support for yaz-client. Introduced
582 command 'sru' which selects method SOAP/GET/POST.
584 Allow missingValueAction to be specified for the sortspec string -
585 function yaz_sort_spec. By default, the missing value action is null.
586 Use ! to specify "abort". Use = followed by stringvalue to specify default
589 Ensured that Present-handler (if defined) is called in GFS before any call to
590 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
591 searchRetrieve requests.
593 Documentation for YAZ is now based on the Docbook XML/XSLT using
594 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
595 is no longer depending on jade/openjade or docbook-to-man scripts.
596 PDF is no longer part of the distribution - but can optionally be
597 made using DSSSL/jadetex or FOP.
599 Added retrieval handling support in Generic Frontend Server to support
600 conversion between MARC/XML as well as XSLTtransforms. See
601 etc/yazgfs.xml for an example.
603 Added Authentication support to Generic Frontend Server in SRU
604 mode. Authentication using HTTP Basic is supported, as is the use
605 of 'x-username' and 'x-password' parameters in the request itself.
607 Added support for a new character set MARC8s identical to MARC8 except
608 that it converts combined characters to single Unicode characters in the
609 Latin-1 range (when possible).
611 --- 2.1.18 2006/04/24
613 ASN.1 compiler 0.4: generates brief Doxygen file header for
614 generated .h/.c files.
616 Utility yaz_iconv now supports conversion to MARC-8.
618 New facilities for the MARC module. The reading - and writing of
619 content are separate methods for the yaz_marc_t handle. The following
620 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
621 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
622 format). Write functions have prefix yaz_marc_write_.. The existing
623 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
624 available. Removed support for OAI-MARC and simplexml (not the
625 simplexml from PHP5).
627 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
628 to be returned for this connection.
630 --- 2.1.16 2006/03/31
632 Allow multiple languages and charsets to be specified with
633 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
634 negcharset iso-8859-1,utf-8
636 Translation of proximity nodes from CQL into PQF now works.
638 Moved to automake 1.8, 1.9.
640 Added function yaz_log_set_handler which allows a log handler to be
641 installed. This handler will be called for all log messages. Output
642 to file is also produced; but that can be disabled by passing NULL
643 fname to yaz_log_init_file.
645 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
647 For SRW (including GFS), accept application/soap+xml as content-type
650 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
651 produces NO stylesheet reference even if a default stylesheet is specified
654 --- 2.1.14 2006/03/14
656 Updated Windows package to include yazd.dll + yazd.lib for the
657 Development component.
659 If the environment variable YAZ_LOG is set, then it is used as a
660 string indicating the default level of logging to use if not
661 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
662 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
663 used as before. So, for example, to omit warnings from YAZ logging,
666 cql_transform() now map structure and other attributes before indexes,
667 so that index-specific structures and other attributes can override
668 defaults. So now a combination of mapping specifications such as:
670 index.dc.date = 1=date-modified 4=5
671 does the right thing.
673 cql_transform() now also respects the "always" mapping specification,
674 which establishes an initial set of attributes to be used for all
675 terms except where overridden by more specific attributes associated
676 with the index, relation or modifier.
678 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
679 which mode to use; one of "post", "get" or "soap" (SRW, default).
681 Fixes for yaz_iconv routines: changed trie-based character set conversions
682 to use only non-negative values for bit fields due to Sun's C compiler not
683 supporting negative values.
685 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
686 sequences where not read correctly. Fix by Rustam Usmanov.
688 Updated win/makefile to use options, settings which makes things
689 compile with VS C 2005.
691 --- 2.1.12 2006/02/01
693 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
695 In ZOOM socket code, use select instead of poll on MacOSX.
697 ZOOM-C now support client-side compilation of CQL into RPN that is
698 sent to the server, enabling CQL to be used against all Z39.50
699 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
700 ZOOM_query object, and submit it using ZOOM_connection_search().
701 The CQL-to-RPN translation uses a configuration file, the name of
702 which must be specified in the Connection's "cqlfile" option.
704 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
705 function, which takes as its start-term parameter a ZOOM_query object
706 (which may have had either CQL or RPN set into it).
709 --- 2.1.10 2005/11/29
711 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
712 GFS to support this as well. Backend handler, bend_srw_update, does the
713 update work. Code contributed by Ko van der Sloot.
715 Allow retrieval of Search Result-1 information in ZOOM by the use of
716 options that are attached to a result set. ZOOM documentation updated
719 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
720 UTF-8 conversion. Patch by Raj Patel.
722 Added option -m to GFS to control formatting of timestamps in log file.
724 Added 'exit' as synonym for 'quit' in yaz-client
726 Added support for specifying SRW resultSetId + resultSetIdleTime in a
727 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
728 for the new members. Patch by Ko van der Sloot.
730 Added support for SRU POST. It is supported for content-type
731 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
733 Do not build the separate Multi-threaded (MT) library libyazthread.la.
734 Instead make the library libyaz.la multi-threaded. Threading as a whole
735 can still be disabled by configure option --disable-threads. Previosly,
736 with older GLIBCs there were problems with MT libs under Apache. This
737 has now been fixed a long time ago.
739 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
742 CQL module modified to be case insensitive for relations/indexes/operations.
744 Fixed bug in CQL transform code: incorrect value relationModifieder
747 Added 'show all' command for yaz-client which retrieves all results
750 Added new yaz-client, xmles, which takes a (private) OID and
751 a document to be sent as an extended service request.
753 Describe new yaz-client commands wait_response and set_auto_wait.
755 Increase TCP/IP listener backlog from 3 (which I am guessing was
756 copied from the SunOS manual entry way back when) so SOMAXCONN, so
757 that the socket will queue as many incoming connections as it's able
758 to handle ongoing connections. In other words, it will never now
759 refuse a connection that it would be able to handle merely because
760 it's not got around to accepting() enough of the pending connections
761 yet. This is the behaviour anyway under Linux, where the listen()
762 argument is ignored; but not under BSD and on systems such as
763 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
764 YAZ-based servers should now be uniform across operating systems in
767 yaz-marcdump uses 64-bit file access on some systems. This is enabled
768 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
769 This allows yaz-marcdump to read large MARC batches (>2 GB).
771 Modified all YAZ source files - except the source which is auto-generated
772 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
775 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
776 corresponding to the existing *_setl() function. These allow option
777 values containing arbitrary valuues.
779 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
780 ZOOM_resultset_sort() in new applications. Its behaviour is identical
781 except that it returns an indicator of whether or not the sort
782 criterion was accepted (0 for OK, -1 for invalid).
786 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
787 MARC output rather than returning "new" buffer.
789 yaz-client warns about unknown init options.
791 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
795 Added support for SRW sort in Generic Frontend Server. Patch
796 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
797 sortKeys - or NULL if none is provided.
799 Fixed bug #307: It was impossible to specify indefinite/no timeout
800 for ZOOM_event. Special timeout value -1 now means indefinite timeout
803 Added support for multiple languages and charsets to be specified in
804 ZOOM. Each charset/language is separated by a blank. If negotiation is
805 in effect in init-response, Option
806 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
807 Code based on patch by Vasiliy Osadchuk.
809 Fixed bug #306: infinite recursion that occurred when calling
810 yaz_log_level_init as the first call (before other log level or
813 Fixed bug in scan handling in front end server: if preferred-Position-In-
814 Response was non-present, a NULL pointer referece was performed.
818 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
819 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
820 now defined for all those error codes. So instead of putting 109 in
821 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
822 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
824 Modified the yaz-marcdump utility to skip garbage bytes between MARC
827 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
829 Program yaz-client now exits and produces an error message if multiple
830 Z39.50 servers are specified on the command line (none or one allowed
833 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
838 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
840 Fixed bug #272: Preserve spacing for CCL terms.
844 Added support for virtual hosts and multiple backend servers for
845 the YAZ frontend server. The configution is XML based and
846 support specificition of CQL to RPN mappings and explain information.
847 See section "Virtual Hosts" in the YAZ manual.
849 Extended OPAC display utility. OPAC display utility renders
850 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
851 to supplement yaz_marc_decode_wrbuf.
853 Fixed a bug in MARC decoder that could caused it to crash for some
854 invalid MARC records. More diagnostics and warnings where added in
855 XML output (warnings, etc are stored in comments).
857 --- 2.0.34 2005/02/08
859 Fixes for UNIX domain sockets. Bug #261.
861 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
863 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
864 Added yaz_marc_subfield_str which defines subfield lead string which is
865 used in YAZ_MARC_LINE format. Default string is blank+$. Added
866 yaz_marc_endline_str which defines end of fields string used in
867 YAZ_MARC_LINE format. Default string is newline.
869 Experimental support for MarcXChange. This format can be produced
870 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
871 http://www.bs.dk/standards/MarcXchange.xsd
873 Added yaz-client commands scansize that sets maximum number of
874 entries to be returned by scan.
876 --- 2.0.32 2005/01/11
878 Added support for SRW scan in yaz-client and Generic Frontend Server.
880 * Added whereInList member to SRW Scan Term.
882 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
884 Fixed NMEM system to return aligned blocks on the smallest boundaries
885 that are suitably aligned for all possible types on the particular
886 architecture YAZ is being built for.
888 --- 2.0.30 2005/01/04
890 Fixed numerious warnings that was issued with newer versions of GCC.
892 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
893 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
896 Make YAZ Generic Frontend Server slightly faster.
898 Enhance (and reduce) logging for Generic Frontend Server.
900 Revert YAZ log system so that it flushes every write operation
901 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
903 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
904 instead of LOG_, due to name clash with syslog(3). LOG_ are still
905 present. New applications should define YAZ_USE_NEW_LOG=1 - this
906 will effectively disable old definitions.
908 --- 2.0.28 2004/11/09
910 Added yaz_log_time_format which specifies log format using
913 Added yaz_log_module_level which returns mask for a module. Value
914 is non-zero mask a if module is enabled; zero if disabled.
916 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
917 in include/yaz/cql.h.
919 Fixed bug #176: Dont throw diagnostics on empty SRU args.
921 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
923 Fixed bug #172: RPM builds does not enable SSL.
925 Doxyfile.in part of dist. Doxyfile generated by configure.
927 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
928 are given and the corresponding component does not exist.
930 Extend CCL documentation in YAZ reference. Describe r=r.
932 --- 2.0.26 2004/10/01
934 Fixed MARC->MARCXML conversion to properly deal with
935 fields, subfields, indicators having non-ASCII characters.
937 Fixed MARC->MARCXML conversion so that ASCII control characters
938 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
941 Added YAZ GFS support for conversion from Z39.50 surrogate
942 diagnostics to SRW surrogate diagnostics.
944 Bug fix: YAZ GFS did not return schema in explainResponse.
946 --- 2.0.25 2004/09/30
948 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
949 now converts recordSchema to elementSetName as well as schema URI.
951 Fixed bug in COMSTACK that prevented HTTP request packages from being
954 --- 2.0.24 2004/09/29
956 Added CCL facility r=r "range" which is similar to r=o "ordered" but
957 does not require white-space before and after the dash in a range, e.g.
958 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
961 Fixed a few AC_TRY_LINK configure tests that did not operate properly
962 due to new GCC removing "redundant" code.
964 Added yaz-client commands scanpos and scanstep that sets preferred
965 position and step-size for scan.
967 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
969 Added CCL utility ccl_qual_buf which parses one or more CCL
970 spec lines in a buffer.
972 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
973 of name and value - ignoring empty lines and comments.
975 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
977 Added odr_get_element_path which returns current element path for an
978 ODR handle. This utility is useful in error handling or user-defined
981 Added ODR_PRINT utility odr_set_stream which is is a more generic
982 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
983 to a write function and pointer to close function. The close function - if
984 non-NULL - will be called during odr_destroy.
986 Fixed bug in CCL parser where truncation char was not removed from
987 right side when truncation=both was in effect.
989 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
992 --- 2.0.23 2004/08/11
994 Fix buffer overrun in CQL parser when dealing with proximity (%).
996 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
997 to UTF-8/UCS conversion is now only based on codetables.xml.
999 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1001 --- 2.0.22 2004/08/06
1003 Add support for more "commit changes" in ZOOM (uses Extended Services).
1005 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1008 Yet another small fix for configure of SSL.
1010 --- 2.0.21 2004/05/14
1012 Fix SSL libs for configure when --with-openssl=DIR is given.
1014 --- 2.0.20 2004/05/10
1016 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1018 SSL comstack now uses yaz.pem certificate file on server side
1019 by default. Certificate filename can be configured by calling
1020 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1022 Fix bug regarding multiple calls to ZOOM_connection_connect.
1024 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1026 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1027 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1029 ZOOM now allows inspection of X509 peer certificate for verification.
1030 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1032 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1033 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1034 as "modular" but it simplifies things.
1036 Added cs_get_peer_certificate to that returns peer X509 PEM.
1038 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1039 NULL if SSL is unavailable.
1041 Documentation about MARC decoding tools.
1043 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1045 --- 2.0.19 2004/03/30
1047 Rename CHANGELOG to NEWS to follow GNU style packing.
1049 Fix bug with missing initialization of member in init_diagnostics.
1050 This bug affects threaded version of GFS server.
1052 --- 2.0.18 2004/03/20
1054 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1057 Ensure zlib.dll is packed with Windows install.
1059 --- 2.0.17 2004/03/17
1061 Fix encoding of xsd:string to use text instead of CDATA.
1063 Fix endless loop in CQL parser with unbalanced ".
1065 Use a more compact way to store MARC-8 conversion tables.
1067 --- 2.0.16 2004/03/16 Debian only
1069 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1072 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1077 --- 2.0.15 2004/03/01
1079 Another fix for decoding of XML packed records.
1081 --- 2.0.14 2004/02/25
1083 Fixes for Chunked encoding. White space not ignored after length spec.
1085 Update NS and use default NS for SRW diagnostic elements.
1087 --- 2.0.13 2004/02/23
1089 Implement ZOOM_resultset_cache_reset which resets record cache.
1091 Implement ZOOM_resultset_sort which sorts a result set.
1093 Implement chunked HTTP transfer.
1095 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1097 --- 2.0.12 2004/02/16
1099 Added member 'schema' to bend_explain_rr structure so that backend
1100 can specify explain record identifier. Defaults to Zeerex 2.0.
1102 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1104 --- 2.0.11 2004/02/16
1106 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1109 Added init command for yaz-client which sends "extra" init request.
1111 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1112 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1114 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1116 Make ZOOM error code for "invalid query".
1118 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1120 --- 2.0.10 2004/02/05
1122 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1125 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1127 Added option -p <file> to make Generic Frontend Server to write PID file.
1129 Added option -D to put Generic Frontend Server in background on its own.
1131 Make ZOOM C recognize option "password". If unset, "pass" is used
1132 (for backwards compatibility).
1134 Fixed a bug in Generic Frontend Server that could make it crash if a
1135 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1138 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1139 Must be issued before open, in order to be in effect.
1141 --- 2.0.9-6 2004/01/12 Debian/Windows
1143 Make the SRU server more picky WRT unknown params, etc.
1145 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1147 New YAZ client command, options, that sets Z39.50 options.
1149 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1150 options from a string of tokens (one token for each option bit).
1152 Update SRW diagnostic code messages.
1154 --- 2.0.9-5 2004/01/07 Debian/Windows
1156 Handle user defined stylesheet for SRW/SRU.
1158 --- 2.0.9-4 2004/01/06 Debian/Windows
1160 Fix bug in decoding of Content-Length.
1162 --- 2.0.9-3 2004/01/06 Debian/Windows
1164 Fix a bug with decoding of XML packed records.
1166 --- 2.0.9-2 2004/01/05 Debian only
1168 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1170 Fix bug in SRW/SRU diagnostics decoding.
1172 --- 2.0.9 2004/01/05
1174 Fixed bug in Generic Frontend Server which could drop records exceeding
1175 preferred message size. Reported and fixed by Irina Dijour.
1177 Fixed calculation of package size for structured records in Generic
1178 Frontend Server. Reported and fixed by Irina Dijour.
1180 Fixed namespace for SRW/SRU diagnostics.
1182 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1184 --- 2.0.8 2003/12/22
1186 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1187 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1190 CQL changes to reflect recent changes to the specification:
1191 * Documentation talks about context sets instead of index sets.
1192 * Documentation talks about indexes instead of qualifiers.
1193 * The CQL-to-PQF transformer's configuration file now uses
1194 "index.set.name = <attributes>" instead of the old form
1195 "qualifier.set.name = <attributes>". (Both forms are still
1196 understood but the latter is deprecated.)
1197 * CQL terms with no explicit index specified are now interpreted as
1198 cql.serverChoice instead of srw.serverChoice (which of course
1199 behaves exactly the same.)
1201 --- 2.0.7 2003/12/16
1203 MARC conversion can now generate ISO2709 output in another
1204 character set. yaz-marcdump uses this facility if you invoke it
1207 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1208 functions from there can be used from C++.
1210 --- 2.0.6 2003/12/04
1212 Frontend server now transfers memory from decoded packages to stream
1215 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1216 references to show up.
1218 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1219 the ZOOM Abstract API. The older names for the same options are still
1220 also supported for the benefit of old applications.
1222 ZOOM-C supports "implementationId" and "implementationVersion" options
1223 to go along with "implementationName". These allow the user code to
1224 specify identification strings to be sent to servers.
1225 Add OID for the new ExtLite attribute set.
1227 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1228 as requested/supplid by Ere Maijala <ere@atp.fi>
1230 For generic frontend server, reverse the order of
1231 "toolkit-supplied / application-supplied" strings sent as implementationId,
1232 Name and Version. Also, remove the spaces around the slash. This brings
1233 the GFS in line with the behaviour of ZOOM-C on the client side.
1235 Add function ZOOM_scanset_display_term.
1237 yaz-client shows scan displayTerm if present.
1239 Utility yaz-iconv is now installed by default along with the man page
1242 Extend configure check for OpenSSL to use pkg-config where available (such
1245 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1246 server to specify uid/gid/mask for socket using the format
1247 unix:[user=uid,][group=gid,][umask=mask,]file=path
1248 If file= is omitted the existing format is assumed, e.g.
1250 in which case the mask is 0666 (rw for everybody).
1252 Major restructure of YAZ source. All source in libyaz is in src directory.
1253 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1254 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1256 Added man page for utility yaz-marcdump (used to be called marcdump).
1257 yaz-marcdump is installed by 'make install'.
1259 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1260 of incoming package failed.
1262 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1264 Change prototype of odr_perror: add const to message string.
1266 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1268 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1269 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1270 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1271 DNS lookup. There should not be any compatibility problems with this
1272 assuming that blocking=1 or 0 is used.
1274 Fix bad reference in UNIX comstack in function cs_addrstr.
1276 Fix for compilation on AIX.
1278 The generic front-end server (server/seshigh.c) now supports returning
1279 Init diagnostics to the client in User-information-field, in
1280 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1283 --- 2.0.4 2003/09/04
1285 Allow any CQL relation (not just all,any,exact,scr).
1287 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1288 that features the same UI.
1290 Implemented command update0 in YAZ client which is equivalent to
1291 update but uses old of Ext Update ASN.1.
1293 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1294 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1295 Previously no OID was used for this info.
1297 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1298 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1299 returns 'malformed search term' otherwise.
1301 SortResponse member resultCount now set to NULL in sort handler of
1304 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1307 Add three new utility functions for translating OIDs between various
1308 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1309 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1310 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1311 char *oid_to_dotstring(const int *oid, char *oidbuf);
1312 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1314 Reverted modifications for ES Update definition for z_IU0Update
1315 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1316 is back to YAZ 2.0.2.
1318 String value attributes for CCL parser.
1320 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1321 which their FirstSearch server returns in Init responses, sometimes
1322 carrying useful diagnostic information when Init fails. This has the
1323 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1324 "z39.50/oclcui.asn", where its definition is somewhat different from
1325 what OCLC document on their web-site, as required to interoperate with
1328 Support for anonymous authentication in yaz-client. Use the command
1331 * Fix the OID of the Index Data-local "admin" Extended Service from
1332 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1333 the 1000, which indicates a locally-defined OID, was a mistake.
1335 --- 2.0.3 2003/06/20
1337 Fix CCL directive @case handling so that it affects string match for
1338 both CCL keywords and qualifiers.
1340 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1341 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1342 Decoder has been updated with ASN.1 changes as listed in
1343 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1344 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1345 z_IUUpdate, remains unchanged.
1347 ZOOM_record_get may now return a record in a specific character set.
1348 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1349 "from" is the character set of record as returned by target. "to" is
1350 the character set to be returned. If omitted, "to" is UTF-8.
1352 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1354 New ODR utility, odr_getelement, which returns name of element for
1355 which encoding/decoding failed.
1357 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1358 in cases where a required element was omitted.
1360 Bug fix: some MARC8 sequences were not converted.
1362 New ZOOM option "step" which specifies number of records to be
1363 retrieved in one chunk. Used in conjunction with "start" and "count".
1365 SRW support for yaz-client. Use scheme http: to use it, e.g.
1368 yaz-client no longer does (un)intelligent character set conversions
1369 by default. Can be enabled with charset and marc_charset commands.
1371 xmalloc trace fix for 64-bit systems such as DEC alpha.
1373 Solaris 2.6 compile fix.
1375 New function, cql_strerror() translates SRW error codes, as returned
1376 by cql_transform_error(), into human-readable English strings. Used
1377 in yaz-client diagnostics when appropriate.
1379 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1380 converts it into a type-1 query which is sent to the server. This
1381 makes CQL available for use with all Z-servers, as opposed to the tiny
1382 minority that can handle CQL queries themselves.
1384 --- 2.0.2 2003/04/28
1386 New Debian package layout similar to the Redhat Package layout.
1388 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1389 and search result respectively.
1391 --- 2.0.1 2003/04/25
1393 Redhat package is now several packages: libyaz (runtime libraries),
1394 libyaz-devel (development and documentation, and yaz (utility programs).
1395 Package spec file by Morten Bøgeskov.
1397 New member 'schema' in struct bend_fetch_rr which the name of requested
1398 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1399 handler MAY set this to reflect the schema of the returned record.
1401 New member 'display_term' in struct scan_entry. GFS now sets member entries
1402 and allocates scan entries to be filled by user scan handler. In previous
1403 version, entries member was allocated by the scan handler. That still works,
1404 but the GFS will ignore member display_term - assuming it was NOT set by
1405 the handler. The fact that the GFS now allocates the entries both allows
1406 for new members and makes a scan handler easier to write.
1408 Fix CQL lex buffer overflow.
1410 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1411 SRU default recordPacking is string.
1413 SRU protocol support for frontend server.
1415 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1417 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1419 Added scan for the ZOOM shell (zoomsh).
1423 * String Identifers for Schemas (Amendment 5).
1424 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1425 Old definition for schema
1426 Odr_oid *schema; /* OPT */
1431 Z_InternationalString *uri;
1432 #define Z_Schema_oid 1
1433 #define Z_Schema_uri 2
1436 * resultCount parameter to Sort Response (Amendment 1).
1437 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1439 Support for SRW 1.0 over HTTP. This is an optional feature and
1440 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1443 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1444 on the same port. SRW SearchRetrieveRequests are mapped
1445 to bend_init,bend_search,bend_fetch,bend_close.
1447 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1449 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1450 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1452 ZOOM connections are SRW based if schem http is used for hostname
1453 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1454 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1456 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1457 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1458 distance=n, order=true/false, relation=le, prox unit=word. If
1459 n is omitted, distance 1 is used.
1461 Fixed problem with C compiler include path in wrong order.
1463 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1464 on Solaris. Patch from Ko van der Sloot.
1466 New MARC decode API. All new functions operate on a yaz_marc_t
1467 handle. The most important new functions are: yaz_marc_create,
1468 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1469 decode and destroy respectively. Decoder can produce formats
1470 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1471 include/yaz/marcdisp.h.
1473 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1474 to UTF-8, UCS-32, wchar_t or Latin-1.
1476 * Prototypes for yaz_iconv_-functions moved to separate header
1477 include/yaz/yaz-iconv.h.
1479 Make a few private functions 'static' in unix.c. This prevents
1480 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1482 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1483 are set when Init Response is received.
1485 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1486 but returns diagnostic set as well.
1488 New function yaz_strerror which is a portable wrapper for
1489 strerror/strerror_r/GetLastMessage.
1491 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1492 is returned for MARC. If type is "oai", then OAI MARC is returned.
1494 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1497 --- 1.9.2 2002/11/26
1499 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1501 Fix bad race conditions on SIGTERM and terminate gracefully in
1504 Move retrieval (data1) module to Zebra since nobody seems to be
1507 Add GRS-1 render for ZOOM using same format as yaz-client.
1509 --- 1.9.1 2002/10/05
1511 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1513 Fix broken ESpec handling in data1 module.
1515 SGML reader parses comments and makes them part of the data1 tree.
1517 Added several type casts so that YAZ compiles as C++ code.
1519 ZOOM didn't handle PDU encoding failures properly.
1521 Added more Bib-1 diagnostics (approved extensions).
1523 GNU configure: better check for iconv.
1525 More portable use of accept, getpeername. Check for socklen_t. Use
1526 int/size_t if socklen_t is not defined.
1530 PQF parser rejects bad queries - including those with extra
1531 characters in them. PQF parser used to silently ignore that.
1532 Cleaner API for PQF added, which allows you to get detailed
1533 error information for bad queries (see yaz/pquery.h).
1535 Fixed bug in ZOOM_record_get for type "database".
1537 Implemented mini iconv library supporting conversions between
1538 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1540 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1542 --- 1.8.9 2002/08/20
1544 Fixed ZOOM C record cache so that preferredRecordSyntax and
1545 elementSetName is used to check for already fetched records.
1547 --- 1.8.8 2002/08/02
1549 Added three members in bend_initrequest structure to facilitate
1550 character set negotiation.
1552 Fixed a bug in frontend server that could cause indefinite
1553 loops under rare conditions.
1555 Revised character set utilities (charneg.h) so that encoding
1556 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1558 For PQF, directive @term <type> sets term type for Scan/Search.
1559 Here <type> is general, string, numeric, null. The term type
1560 is inherited - just like @attr.
1562 New call odr_set_charset that sets character set conversion for
1563 international-strings on a ODR stream. Prototype is:
1564 int odr_set_charset(ODR o, const char *to, const char *from);
1565 The InternationalString is still represented as C string in YAZ
1566 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1567 won't). On the protocol level, you can use any encoding.
1569 Support for UNIX sockets in ZOOM.
1571 Solaris recv sometimes returns errno == ENOENT. It is treated as
1572 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1574 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1575 both client and server. Code by Morten Bøgeskov.
1577 --- 1.8.7 2002/05/22
1579 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1580 that they can be used directly from Visual Basic. You must recompile
1581 your windows APP if you're using ZOOM.
1583 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1584 Commands "lang" and "charset" sets language and character set respectively.
1585 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1586 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1588 Attributes from multiple CCL fields may be OR'ed rather than merged
1589 using directive "@field or". Fields are still merged by default -
1590 equivalent to "@field merge".
1592 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1595 Fixed bug in zget for parameter ExtendedServicesResponse.
1599 --- 1.8.6 2002/03/25
1601 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1603 Client displays USR.1:SearchResult-1 (hits per term).
1605 Additional Search Info for search in Generic Frontend Server.
1607 Fixed CCL parsing of "field=s".
1609 WIN32 installer - using the excellent NSIS software from nullsoft.
1611 Fixed CCL parsing of "field = - <number>".
1613 Added function yaz_marc_decode that decodes MARC for line mode
1614 display or XML (similar to that used by JZKit).
1616 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1617 Z39.50. But ISO/ILL was, however.
1619 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1620 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1622 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1623 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1625 --- 1.8.5 2002/02/03
1627 New YAZ client features: Command completion and new commands:
1628 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1629 Code provided by Jacob Poulsen.
1631 New call oid_trav, that visits all registered OIDs via callback.
1633 Function ZOOM_record_get now returns const char pointer rather than
1634 void pointer. It saves a lot of type casts.
1636 For YAZ client, command "auth" now allows you to set authentication
1637 in IdPass style. It is enabled when three tokens are given - order
1638 is user, group and password.
1640 Fix memory leaks in MARC record handling for ZOOM.
1642 New option for YAZ client, -k <kilobytes> that sets
1643 maximum record size. Similar to -k option for generic frontend
1644 server and yaz-ztest.
1646 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1648 Prefix query parser reports "fail" when bad attribute set is given.
1650 Fix in MARC decoder. Proximity logging. Fix for attribute set
1651 in scan handler for server. Patches by Shigeru Ishida.
1653 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1656 Configure option --with-openssl=<dir> now works when a directory is
1657 specified. Patch provided by Morten Bøgeskov.
1659 New option for YAZ client, -u <auth>, that sets authentication.
1661 ZOOM fix: error information was sometimes "missing", since error
1662 was cleared/reset too when it shouldn't.
1664 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1666 --- 1.8.4 2002/01/04
1668 Scan for ZOOM API. New object ZOOM_scanset. New functions
1669 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1670 ZOOM_scanset_destroy.
1672 New ZOOM function, ZOOM_connection_last_event, that returns type
1673 of last event (such as "receive data", "send data", "apdu received",
1676 New ZOOM option, schema, that specifies schema for retrieval.
1678 New CCL feature. Qualifiers can be aliases for one or more
1679 other qualifiers (if more than one is given, OR is used).
1681 ZOOM uses named result sets if target supports it.
1683 Two new YAZ client commands: . (dot, which sources a script of YAZ
1684 client commands), and ! (to execute shell command.). Implemented
1687 Working on Debian packages.
1689 --- 1.8.3 2001/11/19
1691 YAZ client enables named result sets only if target supports it.
1693 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1695 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1696 with key="host" to get same result.
1698 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1699 Function Z3950_resultset_record(s) returns references to records
1700 "owned" by resultset. To become owner use Z3950_record_clone.
1702 Function z_ext_record handles Extended Services. Thanks to
1705 --- 1.8.2 2001/11/12
1707 CCL Parser fix: ignore token comma when dealing with and-lists.
1709 Documentation updates for COMSTACK.
1711 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1712 Changed prototype Z3950_records. For some functions, int parameters
1713 were changed to size_t.
1715 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1718 New MARC decode/display function, marc_display_exl, which properly rejects
1719 non-ISO2709 records. YAZ client uses it.
1721 --- 1.8.1 2001/10/29
1723 Fix bug: local attribute set wasn't set correctly in PQF strings.
1727 * Old Z39.50 codecs no longer supported.
1729 Added ZOOM C binding. See http://zoom.z3950.org/
1731 Renamed states for COMSTACKs to avoid confusion with events.
1733 Implemented cs_look and proper cs_rcvconnect.
1735 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1737 Configure detects POSIX threads on OpenBSD.
1739 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1740 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1742 When error is returned from present handler, non-surrogate diagnostic
1743 is returned in present response (and fetch handler is no longer called).
1745 * Minor adjustments to pquery parser (PQF). Token characters may be
1746 escaped by using backslash (C-style).
1748 PQF parser allows string attribute values to be specified. For @attr,
1749 non-numeric characters after the equal-sign are treated as strings
1750 (e.g. @attr 9=title).
1752 CCL trunction character may be defined (@truncation in file)
1754 * function zget_ExtendedServicesRequest sets waitAction to
1755 waitIfPossible (was wait).
1757 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1760 CCL operator names may be set in field definition files (CCL_bibset).
1761 See ccl/bib1 for an example.
1763 Fixes in ASN.1 compiler for C++ compatibility.
1765 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1766 and "op_or" to avoid conflict with C++.
1768 Fixed problem with GNU readline detection on Redhat 7.0.
1770 Added step-size for Scan backend handler.
1772 Fixed bug that made the frontend server crash when no attribute
1773 set was specified for scan.
1775 Front-end server automatically switches to original working directory
1776 when installed as an NT service. Previously -w had to be specified to
1779 Added extended attributes for retrieval module (data1), so that data1
1780 records carry d1_readXML/SGML attributes. d1_read also supports
1781 null-data rules ( <tag/>)
1783 On UNIX when POSIX threads are available, a separate library libyazthread
1784 is created. Programmers should link with that library and the yaz library
1785 when using threads. The reason for the split was that some applications
1786 on Linux, such as Apache, doesn't work well when using shared objects that
1789 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1790 (or any frontend server) in SSL mode by specifying ssl: followed by
1791 address. Only tested on UNIX.
1793 Added feature for CCL module. Virtual structure s=al or s=ol generates
1794 and-list and or-list respectively instead of phrase search.
1798 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1799 log_mask_str. This was done to avoid name conflicts with other libraries
1800 (such as other PHP extensions).
1802 Added raw OID member for preferred record syntax (request_format_raw)
1803 and returned record syntax (output_format_raw) for backend fetch method.
1805 Config file yaz-config now accepts options so that it returns specific
1806 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1808 Shared library support for UNIX using GNU libtool.
1810 * Modified backend interface. Request/Response struct's replaced by
1811 one read/write C struct. For example bend_fetchrequest and
1812 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1813 Every handler - even search has to be registered in bend_init
1814 handler. This means that the YAZ library no longer refers to
1815 external functions and it makes it possible to make the whole
1816 thing a single DLL/SO.
1818 Added Segment handler for backend server.
1820 Added Zmbol/Zebra administrative functions to YAZ client.
1822 Threaded frontend server on UNIX (when POSIX Threads are available).
1823 Starting the server with option -T enables multi-threading.
1827 Added configure option --enable-comp/disable-comp to control use
1828 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1829 located in sub directory asn.
1831 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1832 in ${exec_prefix}/bin along with the other programs yaz-client and
1835 GNU automake used to maintain makefiles.
1837 Added several OID's.
1839 Changed retrieval module so that we can load records with no abstract
1840 syntax defined. Tagpaths in these records are fully composed of string
1843 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1847 On UNIX, the generated makefile now supports a proper 'make install'.
1848 The prefix can be set via GNU configure to set the install location
1849 (default is /usr/local).
1851 * YAZ programs client and ztest were renamed to yaz-client and
1852 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1853 locations, such as /usr/bin,/usr/local/bin,etc.
1855 * YAZ Header files were moved from include to include/yaz. YAZ Header
1856 files are referred to as include <yaz/log.h> rather than <log.h>.
1857 The YAZ include path (-I ..) is therefore the same as before. Programmers
1858 should update their #include statements or use -Ipath/include/yaz
1859 instead. The main motivation for doing this change is that YAZ header files
1860 can be installed in "standard" locations /usr/include,/usr/local/include
1861 without introducing conflicts, since ALL YAZ header files are stored
1862 in subdirectory yaz (under /usr/include for example).
1864 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1865 rather than project/workspace files. We switched because project files
1866 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1869 Changed name of logging function, logf, to yaz_log, to prevent name
1870 clash with some math-log functions. The YAZ header log.h defines logf
1871 to yaz_log (#define) so there should be no incompatibilities by this
1874 Added bend_start/bend_stop handlers for server. These handler are
1875 called on start/stop of server. For windows they are called whenever
1876 a service is started/stopped.
1878 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1879 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1880 in util/yc.tcl. The auto-generated C code structures are, in a few
1881 cases, incompatible with the old decoders. There are differences in the
1882 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1883 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1884 The preprocessor variable ASN_COMPILED is defined when the compiled
1885 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1886 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1887 wish to use the old encoders/decoders you can specify --disable-yc
1890 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1891 version so that it supports both new - and old version of DB Update
1893 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1894 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1895 change. The name parameter can be set to 0 in which no name is specified
1896 for the construction. The macros odr_implicit and odr_explicit sets name
1897 parameter to zero for the construction involved. New macros
1898 odr_implicit_tag and odr_explicit_tag are similar to the others,
1899 except that a name parameter is added. For programmers' that don't use
1900 ODR they probably only need to change the call to z_APDU and z_External.
1902 Added access control facility by interfacing the TCP wrapper library.
1903 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1904 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1905 name of the daemon and enables the access control as specified in
1906 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1908 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1909 den Dool <H.M.vdnDool@kub.nl>.
1911 Added reference ID parameter to most functions in server API - refer
1912 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1914 Changed name of ccl library to libccl.a (was ccl.a).
1916 Fixed bug in decoder for Explain (Category TargetInfo).
1918 Added support for GNU readline in client. Thanks to Jacob Poulsen
1919 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1921 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1922 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1923 IMPLEMENTATION! This change was made to the development version before
1924 the ZIG decided to retract the amendment. If any users MUST be
1925 compatible with the original Update definition, PLEASE CONTACT US, and
1926 we will include a separate definition corresponding to the old Update
1927 ES. Note that because of the change to the ASN.1 of the
1928 TaskPackageRecordStructure we cannot define a single structure that
1929 will support both versions.
1931 * Added const modifier to buffer parameter for some ODR/BER encoding
1932 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1933 completeWAIS, odr_dumpBER.
1935 Fixed bug in client.c which caused a crash when a scanResponse didn't
1936 contain positionOfTerm.
1938 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1939 * will cause an error in a client if a non-YAZ target sends both a
1940 * list of Scan entries and non-surrogate diagnostics.
1942 Retrieval module enhancements. Tag sets may be typed in the reference
1943 to it. From the .abs-file the "tagset" directive takes a third optional
1944 integer type for the tag set referenced. From a .tag-file the "include"
1945 directive takes a third optional type as well. The old "type" directive
1946 in the tag set itself is still recognized but acts as the default type
1949 Backend interface change. Individual Scan terms returned from bend_scan
1950 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1951 in include/backend.h.
1953 Retrieval module enhancements. Multiple tag sets and attribute sets may
1954 be specified in abstract syntax specs. Revised the error/warning for
1955 logging messages reported by the retrieval module when reading the
1958 Object Identifier system (oid_..) changed. The API is backwards
1959 compatible but the oid-routines now allocates new OID's when needed.
1960 Raw OID's may be specified in oid_getvalbyname.
1962 YAZ now uses GNU configure to generate Makefile(s).
1964 * Minor changes in some of the member names of DeleteResultSetRequest and
1965 DeleteResultSetResponse. See include/proto.h.
1967 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1968 and added member 'languages' in TargetInfo (which was missing).
1970 Changed the way attribute sets are handled in the retrieval
1971 module. These are now cached, just like the abstract syntaxes
1974 Changed YAZ so that it links with compiled ASN.1.
1976 Added Explain-schema definitions and mapping routines. The following
1977 Explain categories have been implemented: AttributeDetails,
1978 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1980 Fixed minor bug in Windows version of Server Library.
1982 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1984 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1986 Added EXTERNAL: UNIverse Resource Report (non-standard).
1988 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1989 ENUMERATED and SET OF.
1991 * Added 'const' to some of the char pointer arguments for the
1992 functions, data1_read_node, data1_getelementbytagname,
1993 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1996 Fixed bug in data1_insert_taggeddata - the last_child member of
1997 parent wasn't initialised.
1999 * Changed data1_read_record and data1_read_node so that the supplied
2000 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2001 doesn't refer to any parts of the "SGML"-buffer.
2003 Fixed bug in server library (Windows version of statserv_remove).
2005 * Changed code so that it compiles as C++. The type definition
2006 of Odr_fun which is a member of Odr_arm was changed. The result is,
2007 that an explicit typecast is needed for the fun pointer when
2008 using Odr_arm - as in:
2009 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2011 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2013 Implemented the new structured date and time definition as approved
2014 by the ZIG. Added schemaId element to the specificTag in Espec-1
2015 (also approved at the last ZIG). Thanks to RVDM.
2017 Added some Object identifiers (RVDM).
2019 Changed the Update Extended Service (RVDM).
2021 Added command "refid" to client which specifies referenceId for
2022 the following requests.
2024 Implemented extended service handling for server. See ztest.c
2025 for an example as well as backend.h. New handlers are registerd
2026 in the Init handler.
2028 * Changed interface for sort in server.
2030 Added new members to statserv_options_block. It allows a server
2031 to read options from another source than just the command line. Thanks
2032 to Charles Woodfield.
2034 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2035 renamed to zboolean. Some C++ compilers complained about the name.
2037 Minor changes to gils.abs. Added index 's' (sort) on title
2038 and date/time-last-modified.
2040 --- 1.4pl2 1998/1/30
2042 Fixed bug in server library regarding inetd mode (-i). This bug
2043 was introduced by release 1.4.
2045 --- 1.4pl1 1998/1/29
2047 Added sort facility in client and backend server interface.
2049 Fixed problem with dependencies in Makefile(s).
2051 Fixed bugs for encoders/decoders of extended services and
2054 Implemented sub-tree feature for schemas. Sub-trees are
2055 referenced in *.abs-files. See explain.abs for an example
2056 of the use of this feature.
2058 Modified bib1.att; local attributes for ANY didn't include
2059 ANY itself (only affects use of the retrieval module).
2061 Fixed bug in plain SGML reader in function data1_read_node:
2062 tags with prefix "var" was incorrectly interpreted as variants.
2064 Added feature "sub-schemas" to enable references to - and definitions
2065 of - group of elements.
2067 * Removed member parent from type data1_element (in data1.h).
2069 Implemented function odr_nullval() that returns the value of
2072 * Removed member num_children from data1_node (in data1.h).
2074 Made NT service interface part of the server library. The
2075 function statserv_main uses the NT service when required and
2076 calls the statserv_start / statserv_close routines.
2078 Routine zget_SearchRequest and zget_PresentRequest fills
2079 resultSetName/Id member with "default" instead of "Default".
2081 Fixed memory leak in server. Request queue member wasn't freed.
2083 Fixed nmem_exit so that memory is freed.
2087 Revised the CCL parser utility to be thread safe.
2089 Added function, oid_ent_to_oid, to replace the function
2090 oid_getoidbyent, which is not thread safe.
2092 * Added nmem_init and nmem_exit to initialize and release
2093 NMEM resources. Function nmem_init should be called once in the
2094 initial thread before NMEM/ODR is used. statserv.c and client.c
2095 have been changed accordingly. The change was necessary to make
2096 NMEM thread safe. The NMEM memory pool is shared amongst threads
2097 in a process. Unix-based applications will still work fine without
2100 Added NT Services interface for the the Z39.50 (statserv) Server.
2101 Refer to the ztest.c source on the usage.
2103 Windows 95/NT port using MSVC5.0. Project files are included in the
2106 * Defined new 'global' handle for the retrieval (data1) system. The
2107 new handled, data1_handle, describes the state of the data1 system.
2108 This handle is passed as first argument to virtually all
2109 data1 related routines. The functions data1_create and data1_destroy
2110 creates and destroys a data1 handle respectively.
2112 Added ODR encode stream member to all backend request structures
2113 init, search, scan etc. This stream should be used to allocate all
2114 memory used for the response when thread safe operation is needed.
2116 Changed the comstack utility, cs_addstr, to be thread safe. The
2117 returned hostname string returned by the function is now part the
2120 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2121 function. The cs_straddr takes a COMSTACK handle as argument, so this
2122 function must be used after cs_create and before bind/connect.
2123 This function is thread safe.
2125 Moved test server to 'ztest' directory - generic server code still
2126 in 'server' directory.
2128 Made prefix query (pquery.c) utility thread safe.
2130 Added new function modifier YAZ_EXPORT to 'export' public DLL
2131 functions when using windows (see include/yconfig.h).
2133 Added definitions to the OID database (util/oid.c) (RVDM).
2135 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2137 Added call to ccl_rpn_delete in client program.
2139 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2140 release of RPN structure.
2142 Added support for C++, headers uses extern "C" for public definitions.
2143 With input from RVDM.
2145 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2146 Thanks to Ronald van der Meer (RVDM).
2148 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2150 Added support for private extensions to the OID database
2151 (oid_setprivateoids()). Thanks to RVDM.
2153 Added optional, physical ANY (key replication)
2155 Fixed null-reference problem in GRS-1 output filter.
2157 Proximity operator added to Prefix Query Format (PQF).
2159 In test client command "base" accepts multiple databases.
2161 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2165 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2167 Smallish bug-fixes in the new encoders/decoders (explain).
2169 Bug fixed in DeleteRequest.
2171 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2173 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2175 Added SOIF syntax (using private OID for now) to retrieval module and client.
2177 Added Update extended service.
2179 Added SearchResult-1 additional info structure.
2181 Added optional CCL (ISO8777) interpreter as separate module. Available
2184 --- 1.2 1996/6/10 (1st anniversary release)
2186 Added Summary record syntax. Lightly tested.
2188 Added OPAC record syntax. Untested.
2190 Added ResourceReport service encoders/decoders. Untested.
2192 Fixed bug in z_Unit - wrong tagging on unitSystem.
2194 Fixed bug in the DiagRecs decoder.
2196 Added options for max PDU size and session timeout to frontend-server.
2198 Added documentation of query-language parsers and other supporting utilities.
2200 [frontend-server] Added Attribute set to the bend_scanrequest API.
2202 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2203 surrogate diagnostics were generated.
2205 [retrieval] Allow multiple local values for attribute.
2207 [retrieval] Allow multiple attributes per element in .abs files. index type.
2209 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2211 --- 1.1pl2 1996/4/10
2213 Minor changes, mostly specific to Zebra's requirements (retrieval)
2217 Repaired bug in frontend server when running multiple listening
2218 endpoints in dynamic mode.
2220 z_External() now won't break if a known, ASN.1 value comes encapsulated
2221 in an octet-string. The value will pass through unmodified in an Odr_oct.
2223 Added a bit of code to the demo client to decode & display
2224 ASN.1-structured records represented in the octet-aligned branch of
2225 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2227 Added z_ext_getentbyref() to the ASN module. Doc updated.
2229 * Completed the SCAN definition in the ASN module. This may break SCAN
2230 code based on older YAZ-versions at compile-time. The fix is easy -
2233 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2234 under the SCAN definition. Remember to initialize this, server-people.
2236 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2237 that this does not extend to ODR and ASN.
2239 Comstack allows insertion of established socket (primarily for
2240 inetd-operation of servers). Doc updated.
2242 Front-end server can now start from the inetd in TCP mode. Doc
2245 --- 1.0pl4 1996/1/24
2249 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2250 the rank and record number.
2252 Adjustments to the frontend server.
2254 Fixed diagnostic BER dumper. It ignored the file argument.
2258 Various changes to retrieval module.
2260 Changed the union discriminators of the protocol files from enums to
2261 ints paired with #defines.
2263 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2266 *Changed operator in the RPN structure to 'roperator', again to avoid a
2269 Fixed problems in Explain decoders/encoders.
2271 --- 1.0pl2 1995/12/6
2273 Memory bug in log module fixed.
2275 --- 1.0pl1 1995/12/5
2277 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2279 Bug in Explain DatabaseInfo module fixed.
2281 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2285 The shift to v1.0 signals that we now consider the *core* functionality
2286 of YAZ reasonably stable (the core being more or less equivalent to
2287 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2288 tested (Explain not at all - though that will happen soonish).
2290 Minor changes to code to support Windows port.
2292 Various minor changes after we're getting to use GRS-1 & co. more.
2294 Added Espec-1 format.
2296 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2297 of the protocol and it cannot be selected when encoding (maps into 'string'
2298 when decoding). Needed to talk to some servers.
2300 Demo client can request simple element set names.
2302 Added Diagnostic Format encoders/decoders.
2304 Added simple Close handling to frontend server (no hooks for resource
2305 reporting yet), and demonstration client.
2307 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2309 --- 1.0b3 1995/08/24
2311 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2312 handled incorrectly when records were requested in the searchResponse. This
2313 will only affect you if you use the frontend-server.
2315 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2316 Test-client will ask for and print GRS1. Ztest will return dummy records
2319 Added Explain encoders/decoders to the service-level API. Untested.
2321 Added Extended Services: Item Order encoders and decoders to the Service-
2322 level API. Untested. We could use a recent copy of the pertinent bits
2323 of the ILL protocol to add those bits.
2325 Added diagnostic format 1 encoders/decoders to the service-level API.
2328 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2329 odr_cons.c, which causes a more correct output.
2331 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2332 was always set to 0 when no records were requested in the searchRequest.
2334 * Added better external-handling. This shouldn't harm old code that
2335 *encodes* externals. It can break code that looks for a
2336 'single-ASN1-type' representation, since those types that are known
2337 are now decoded immediately. Look at the SUTRS sample code in
2338 seshigh.c and client.c. Documentation updated.
2340 Handling of structured records in bend_fetchresponse. Length -1 marks
2341 structured record, type is deduced from format field.
2343 --- 1.0b2 1995/06/27
2344 Fairly quick maintenance release to add SUTRS support.
2346 Fixed handling of SUTRS records in the demonstration client.
2348 * Added format field to the bend_fetchrequest and bend_fetchresponce
2349 structures of the backend API (frontend server). When the record is
2350 returned, the value of the format field is mapped to an OID. The
2351 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2352 of the record. The special value VAL_NONE in the bend_request means
2353 that no specific format was requested by the client. Documentation
2354 updated accordingly. Test server (ztest) will return a fixed dummy
2355 SUTRS record if your client requests SUTRS.
2357 Documentation updated accordingly.
2359 You can now set external libraries and RANLIB support in the top-level
2363 First public release.
