3 Document --with-xml2 option.
5 Added OPAC XML XSD (etc/opacxml.xsd).
7 Allow glob mask for name attribute in retrieval element for the
8 generic frontend server's retrieval facility.
10 Changed yaz_poll_poll to return yaz_poll_except for all returned events
11 except POLLIN/POLLOUT.
13 Fixed error handling in cs_listen. Bug #2037.
17 Fixed version in yaz/yaz-version.h.
19 Fixed bug #2027: Crash when closing connection.
21 Changed configure so that ICU support is only enabled if only ICU
22 and Libxml2 is available (because the ICU chain is XML based).
26 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
27 is built. Only this DLL depends on the ICU runtime.
29 yaz-ziffy is no longer part of YAZ. It is distributed separately by
30 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
32 Changed license of CCL module to 'Revised BSD'. After consultation with
33 remaining members of the original EUROPAGATE consortium, we are re-issuing
34 the CCL module without a separate license. The software was developed by
35 Index Data as part of a research project. The special license was included
36 to help feed usage information back to the project consortium to support
37 project evaluation. At this time, the project consortium has long-since
38 disbanded, and the majority of the original principals have retired. At the
39 same time, we have significantly modified the software during the following
40 years, to the point where very practically no original code remains. To
41 simplify re-use of the software, we have contacted those members of the
42 consortium who could be reached, and agreed to re-issue the module as a
43 proper part of the YAZ package.
45 Tcl scripts uses /usr/bin/tclsh as preferred shell.
47 CQL closer to being version 1.2 compliant. CQL also allows free-form
48 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
51 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
52 bug could make Extended services handling crash in the ZOOM layer. This
53 bug was only present in YAZ 3.0.18.
57 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
60 yaz-marcdump reads and writes collection wrapped records.
62 Handle OPAC for record conversion module.
64 Fixes for ICU wrapper.
66 Allow ICU libs to be controlled with --with-icu .
70 Added yaz_poll which is a wrapper for select/poll. When poll is available
71 and non-buggy, it is used, by yaz_poll . This allows more than 1024
74 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
75 functionality through an XML based configuration (ICU chain). This system
76 is useful for search facilities such as Pazpar2 and Zebra that needs to
77 perform tokenization of indexed material. The ICU code in a separate
78 library libyaz3_icu.a.
80 Added HTTP tunnel facility for COMSTACK, bug #1752.
81 This is a facility that allows a Web proxy, such as squid, to tunnel
82 Z39.50 traffic. This facility is "transparent" to must applications
83 using YAZ. It's enabled by using pseudo transport connect: followed by
84 the proxy address, followed by command, then follwed by he regular
85 "virtual" addresss. For example,
86 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
88 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
92 Fixed bad memory reference in ZOOM_record - cuased by member not being
93 initialized. This was a problem only in YAZ 3.0.12.
95 Fixed bug in conversion from MARC to XML: Non-XML characters in control
96 fields were not removed.
98 Changed the way C code is generated from codetables.xml. Made a MARC-8
99 conversion trie for each characterSet section rather than codeTable.
100 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
101 of codetables.xml from Larry Dixson, LOC. Bug #1464.
103 --- 3.0.12 2007/09/12
105 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
106 from ZOOM_record_error).
108 ZOOM C function ZOOM_record_get returns record schema for type="schema".
110 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
112 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
114 Better SRW-to-Bib-1 diagnostic mapping.
116 ZOOM C and yaz-client announces SRU version 1.2 by default.
118 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
121 Fixed in yaz_sru_decode to allow other version than 1.1.
123 --- 3.0.10 2007/08/22
125 Added support for SRU scan for ZOOM.
127 Added support for the use of the older versions or Extended Service
128 Update in ZOOM. To faciliate this, an option "updateVersion" may be
129 set to the version , 1=first, 2=second, 3=third. The third version is
130 what ZOOM C has used so far. And that, obviously, is the default.
132 Added support for CCL queries in Z39.50 queries sent to the GFS (and
133 therefore in Zebra and in SimpleServer-based applications). The new
134 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
135 qualifier file used to transform incoming CCL queries into Type-1 RPN,
136 which is passed into the back-end search callback function.
138 Added support for HTTP Basic authentication in clients: the SRU/W
139 codec encodes the username/password elements of the PDU structure
140 appropriately, and these may be set using the "user" and "password"
141 options in ZOOM-C applications (the same options that are used for
142 Z39.50 authentication).
146 Fixed bug #1208: SSL appears to be broken in ZOOM.
148 Fixed bug #1206: Libxml2 include path weirdness.
150 Added oid_name_to_dotstring.
152 Allow elementSetName to be specified for ZOOM C record update.
154 Allow waitAction to be specified for ZOOM C based for Extended Services.
156 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
157 syntax OID. Bug introduced in YAZ 3 series.
159 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
163 Fixed bug #1157: yaz-client does not read .yazclientrc from current
164 directory. yaz-client now reads commands from file given by option -f
165 if specified; then tries to read .yazclientrc in current directory.
166 Failing that, it reads .yazclientrc from user's home directory.
168 Added support for correlationInfo Note and ID for Record Update via
171 Added yaz-client command querycharset which specifies character set for
172 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
173 (termListAndStartPoint).
175 Charset ISO5428:1984 is an alias for ISO5428-1984.
177 Implemented a way to perform scan in a result set using Z39.50. This
178 is achieved by attaching the result set name in the characterInfo
179 (type InternationalString) of OtherInformation in the Scan Request PDU.
180 The result set is identified in the otherinformation by the new OID:
181 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
182 This allows for scan in result set and faceted search . Zebra did some
183 of this in the APT term using attribute type 8 and value being result
184 set. Using the OtherInformation approach for this is cleaner and easier
185 to work with in proxies and the like. This facility can be used in
186 yaz-client using new command setscan which takes a result set as first
187 argument, start position (APT) as second.
189 Changed decoding of SRU XML packed records to deal with servers that
190 have recordData with XML data with multiple root nodes. Also make
191 comparison for recordPacking case insensitive. Again, one server
192 returns "XML" where others return "xml".
194 For SRU responses allow Content-Type application/xml as well as text/xml.
198 Fixed bug in character set conversion of BER strings. Bug introduced
203 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
205 For OID class, use oid_class consistently.
207 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
210 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
211 character set for bibliographic information interchange". By Giannis Kosmas.
213 Added documentation on new OID API.
217 Changes to generic frontend server interface: added new member
218 'query_charset' for bend_initrequest structure. A backend init handler
219 should set this member to its native character set for query terms.
220 When defined, the frontend server logic will announce this character set
221 to a client if the negotiationModel bit is set by the client. All server
222 implementors are encouraged to specify this. If a backend server does not
223 specify this a warning is issued using yaz_log(YLOG_WARN,..).
225 Added CCL utility to remove terms (stop words) from resulting RPN
226 tree. This is handled by functions with prefix ccl_stop_words_ .
228 New ZOOM C option, "rpnCharset", which allows client-side conversion of
229 terms in RPN queries.
231 Clean-up the CCL API. Moved some internal structures from ccl.h to
232 private header cclp.h. Changed ccl_parser_create so that a Bibset must
233 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
234 This is replaced by ccl_parser_find_str which takes a string instead.
236 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
237 libyaz.la is the core of YAZ except the generic frontend server and
238 does not depend on POSIX threads anymore. libyaz_server.la is the
239 generic frontend server facilities and uses POSIX thread functionality
240 if available. The libyaz.la no longer depends on POSIX threads because
241 the number of global structures is limited. NMEM no longer re-uses blocks
242 between threads ; it simply free's memory immediately but allocates in
243 "large" chunks as usual. We don't expect any performance penalties
244 because of this. The yaz_log system is still using a global log_level so
245 caution must be taken when modifying it with yaz_log_init_.. +
246 yaz_log_mask_str. This, however, should not cause any trouble because
247 these functions are called during initialization of application code
248 anyway. `yaz-config --libs server` returns libs for server applications;
249 `yaz-config --libs` returns libs for non-server applications.
251 New OID database - with public definitions in oid_db.h. Removed old OID
252 database including the head oid.h and definitions such as enum oid_value
253 and struct oident. The new OID database uses the same string names as
254 before but the 'protocol' is gone. There are now only two representations
255 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
256 converts from string to OID; functions with prefix yaz_oid_to_string
257 converts the other way.
259 Change to emit_term() in CQL-to-PQF query translation: when a term has
260 the /regexp relation modifier, do not process it for leading and
261 trailing "^" and "*", which have quite different meanings in regular
264 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
265 write handlers no longer carries a 'last' parameter. This will make
266 yaz_iconv flush "less" characters. A flush is performed by call to
267 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
269 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
270 removed, because function yaz_query_to_wrbuf does the same.
272 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
273 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
275 Deprecated MARC utility functions removed.
277 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
280 Branch split: YAZ_2_1_55_branch
282 --- 2.1.54 2007/03/16
284 Fix to ZOOM-C so that transparent reconnection is properly handled on
285 connections that are in asynchronous mode.
287 Fixed compilation on OpenBSD 4.0.
289 Large strings in GRS-1 records are now properly displayed in yaz-client.
291 Added character conversion support for "advancegreek"; based on patch from
294 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
295 sequence is met. Before the error was not set so it would be unknown.
297 Adjust yaz-marcdump MARC reader so that it skips until record separator
300 --- 2.1.52 2007/03/07
302 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
303 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
304 fd_set structure used as a bitmask for the FDs to be selected on.
306 Using ACX_PTHREAD macro to check for POSIX threads.
308 Fixed have-vsnprintf check.
310 --- 2.1.50 2007/02/23
312 Fixes for configure on BSD. Bug #900.
314 Added snprintf/vsnprintf wrappers for systems that don't have
315 limits (heavens forbid).
317 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
318 created before all previous tasks were completed and removed from the
319 task queue, the new task could be removed by a mistake.
321 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
323 Implemented pass-through CQL-to-PQF conversions. Bug #861.
325 Fixed bug #832: Problem with MARC/charset in yaz-client.
327 Fixed bug #668: save command line history for yaz-client.
329 Fixed bug #830: pkg-config support.
331 --- 2.1.48 2007/01/23
333 Extended ZOOM result set options with two options that may be read by
334 a client: resultSetStatus and presentStatus with values as specified for
336 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
338 Fixed bug #827: Using SSL fails on Debian etch.
340 Fixed bug #826: Weird looking chars for set of MARC records.
342 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
343 that is treated as an ItemOrder with itemRequest being an XML document
344 external. The value of "doc" is the content.
346 Extended the GFS search facility. New member of bend_search_rr
347 'estimated_hit_count' signals that hits is known to be an estmate
348 (higher or lower than real hit count). New member 'partial_resultset'
349 signals that the search was partial (hit count is lower or equal than
350 real hit count). For Z39.50, the information is stored in resultSetStatus
351 member of SearchResponse APDU. For SRU, the information is signalled
352 via SRU diagnostic 59: "Result set created with valid partial results
355 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
357 --- 2.1.46 2007/01/13
359 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
361 Added ZOOM_connection_peek_event.
363 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
364 the following new functions:
365 ZOOM_event_nonblock, ZOOM_connection_process,
366 ZOOM_connection_get_{socket,mask,timeout},
367 ZOOM_connection_fire_event_{timeout,socket}.
368 The existing blocking event handler, ZOOM_event, is a wrapper for the
369 + blocking ZOOM_event_sys_{poll,select}.
371 Implemented function ccl_xml_config which parses XML version of CCL
372 configuration (bug #798).
374 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
376 Added timings utility (yaz/timing.h)
378 --- 2.1.44 2007/01/03
380 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
383 Fixed bug #779: Rotation of apdu.log fails.
385 Fixed for character set conversions:
386 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
387 Honor G1 set in MARC-8 decoding.
389 --- 2.1.42 2006/12/17
391 Fixed bug #775: char conversion does not handle Alternative UTF-8
394 Implemented function yaz_marc_read_line which parses MARC line format
395 records. There is a wealth of formats out there. So far, this function
396 reads line records produced by yaz_marc_write_line.
398 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
399 more generic and easier to remember(!) options: -i format and -o format
400 which specifies input format and output format respectively - where
401 format is one of "marc", "marcxml", "line", "marcxchange".
403 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
404 does not print anything except warnings for records.
406 For yaz-marcdump, added support for MARC split into files (-s) with a given
409 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
410 spec, at http://www.loc.gov/standards/sru/record-update/
411 This has changed the binary layout of the following structs:
412 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
413 bend_update_rr . Patch by Ko van der Sloot.
415 Added GFS utility function bend_assoc_is_alive which returns 1 if
416 association is still alive (client is connected); 0 otherwise (client
417 closed connection). This allows busy servers to stop working for
420 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
421 been a separate piece of software. This version of ziffy has been modified
422 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
424 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
426 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
427 Client code may now interrogate options such as "init_opt_sort" to
428 find out whether the server claims to support various options.
430 --- 2.1.40 2006/11/27
432 Added utilities yaz_{set,get}_esn to set/get element set name from
435 Removed the build of libyazthread.la. The libyaz.so is the threaded version
436 of YAZ and has been so since YAZ 2.1.10.
438 Implemented ZOOM_record_error which returns error information for
439 record (surrogate diagnostic).
441 --- 2.1.38 2006/10/31
443 Updates for SRU Update by Ko van der Sloot:
444 1. Changed name from "operation" to "action"
445 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
446 versions in the code, marked as 'backward compatible'.
447 3. Added diagnostics for SRU Update.
449 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
451 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
453 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
455 For GFS, fixed problem with SRU diagnostic 'First record position out of
456 range' being issued for 0 hits.
458 zoomtst10 part of Windows Build.
460 --- 2.1.36 2006/10/13
462 Implemented yaz_filepath_comp which splits a path into file path
463 components (required by Zebra 2.0.3+).
465 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
466 BSD inspired license until now so this should not have any real impact on
467 anybody. See http://www.opensource.org/licenses/bsd-license.php
469 Fixed bug #687: Missing log lines.
471 Fixed bug #678: CQL to PQF translation does not preserve double-quote
474 Fixed bug #689: SRU diagnostics to be added.
476 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
477 whether a connection is idle (no more work do do).
479 --- 2.1.34 2006/10/04
481 Change type of optval from long to int for invocation of setsockopt with
482 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
484 Added support for specifying the max log file size for the Generic
485 Frontend Server. The size is given with option -r.
487 --- 2.1.32 2006/09/21
489 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
491 --- 2.1.30 2006/09/17
493 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
496 Fixed bug in Generic Frontend Server that could cause a server to stop
497 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
499 For the generic frontend server, the maximum record size is used as maximum
500 size of incoming packages (SRU + Z39.50). The value until was previously
501 only used in Z39.50 Init negotiation and, later, in a session controlled
502 sizes of records returned. This is controlled using -k option. It can be
503 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
505 --- 2.1.28 2006/09/04
507 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
510 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
512 New option for yaz-marcdump -lpos=value which allows setting a portion
513 of MARC header to a certain value.
515 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
517 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
518 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
520 --- 2.1.26 2006/08/15
522 Fixed problem with SRU mode type (soap, get, post) for yaz-client
525 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
527 --- 2.1.24 2006/08/08
529 Fixed MARC ISO2709 encoding routines to deal with character set
532 Minor changes to GFS logging. Database included in search request log
535 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
536 cached/multiple records.
538 Shared libraries are built by default on Unix+configure.
540 Changed cql2pqf transformation to use a different evaluation order. The
541 new order is: always, relation, structure, position, truncation, index
542 and relationModifier. Old order was: always, relation, relationModifier,
543 structure, index, position, truncation. Note that the the latter ones
544 override former ones for identical attributes.. The new scheme means that
545 it is possible to override any existing attribute with a relationModifier.
546 And also that it is possible to override everything for the index rule
547 (except the ones listed in relationModifier). No order is perfect but this
548 one, we believe, covers more real cases.. The "always" should have been
549 called "default", since the attributes there can be overridden with all
552 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
553 compilation phase, but also for yaz-config --cflags output. This allows
554 us to have public headers with Libxml2 stuff in them . It should also,
555 eventually, make Libxml2 checks redundant in packages using YAZ, such
558 --- 2.1.22 2006/06/15
560 Changed SRU update structure bend_update_rr so that SRU diagnostics are
561 stored in uri, message and details.. Previously diagnostics were stored
562 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
563 compatibility.. but he's probably the only one affected, so.
565 Added support for CCL, compiled on the client side, in ZOOM-C. This
566 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
567 input; the resulting query objects can be used for for searching with
568 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
570 YAZ' configure searches for OpenSSL by default.
572 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
573 SL_CTX_use_certificate_file. See
574 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
575 for more info. Thanks to Ko van der Sloot.
577 --- 2.1.20 2006/06/02
579 Bug #600: SRU GET, POST support for yaz-client. Introduced
580 command 'sru' which selects method SOAP/GET/POST.
582 Allow missingValueAction to be specified for the sortspec string -
583 function yaz_sort_spec. By default, the missing value action is null.
584 Use ! to specify "abort". Use = followed by stringvalue to specify default
587 Ensured that Present-handler (if defined) is called in GFS before any call to
588 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
589 searchRetrieve requests.
591 Documentation for YAZ is now based on the Docbook XML/XSLT using
592 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
593 is no longer depending on jade/openjade or docbook-to-man scripts.
594 PDF is no longer part of the distribution - but can optionally be
595 made using DSSSL/jadetex or FOP.
597 Added retrieval handling support in Generic Frontend Server to support
598 conversion between MARC/XML as well as XSLTtransforms. See
599 etc/yazgfs.xml for an example.
601 Added Authentication support to Generic Frontend Server in SRU
602 mode. Authentication using HTTP Basic is supported, as is the use
603 of 'x-username' and 'x-password' parameters in the request itself.
605 Added support for a new character set MARC8s identical to MARC8 except
606 that it converts combined characters to single Unicode characters in the
607 Latin-1 range (when possible).
609 --- 2.1.18 2006/04/24
611 ASN.1 compiler 0.4: generates brief Doxygen file header for
612 generated .h/.c files.
614 Utility yaz_iconv now supports conversion to MARC-8.
616 New facilities for the MARC module. The reading - and writing of
617 content are separate methods for the yaz_marc_t handle. The following
618 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
619 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
620 format). Write functions have prefix yaz_marc_write_.. The existing
621 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
622 available. Removed support for OAI-MARC and simplexml (not the
623 simplexml from PHP5).
625 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
626 to be returned for this connection.
628 --- 2.1.16 2006/03/31
630 Allow multiple languages and charsets to be specified with
631 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
632 negcharset iso-8859-1,utf-8
634 Translation of proximity nodes from CQL into PQF now works.
636 Moved to automake 1.8, 1.9.
638 Added function yaz_log_set_handler which allows a log handler to be
639 installed. This handler will be called for all log messages. Output
640 to file is also produced; but that can be disabled by passing NULL
641 fname to yaz_log_init_file.
643 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
645 For SRW (including GFS), accept application/soap+xml as content-type
648 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
649 produces NO stylesheet reference even if a default stylesheet is specified
652 --- 2.1.14 2006/03/14
654 Updated Windows package to include yazd.dll + yazd.lib for the
655 Development component.
657 If the environment variable YAZ_LOG is set, then it is used as a
658 string indicating the default level of logging to use if not
659 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
660 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
661 used as before. So, for example, to omit warnings from YAZ logging,
664 cql_transform() now map structure and other attributes before indexes,
665 so that index-specific structures and other attributes can override
666 defaults. So now a combination of mapping specifications such as:
668 index.dc.date = 1=date-modified 4=5
669 does the right thing.
671 cql_transform() now also respects the "always" mapping specification,
672 which establishes an initial set of attributes to be used for all
673 terms except where overridden by more specific attributes associated
674 with the index, relation or modifier.
676 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
677 which mode to use; one of "post", "get" or "soap" (SRW, default).
679 Fixes for yaz_iconv routines: changed trie-based character set conversions
680 to use only non-negative values for bit fields due to Sun's C compiler not
681 supporting negative values.
683 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
684 sequences where not read correctly. Fix by Rustam Usmanov.
686 Updated win/makefile to use options, settings which makes things
687 compile with VS C 2005.
689 --- 2.1.12 2006/02/01
691 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
693 In ZOOM socket code, use select instead of poll on MacOSX.
695 ZOOM-C now support client-side compilation of CQL into RPN that is
696 sent to the server, enabling CQL to be used against all Z39.50
697 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
698 ZOOM_query object, and submit it using ZOOM_connection_search().
699 The CQL-to-RPN translation uses a configuration file, the name of
700 which must be specified in the Connection's "cqlfile" option.
702 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
703 function, which takes as its start-term parameter a ZOOM_query object
704 (which may have had either CQL or RPN set into it).
707 --- 2.1.10 2005/11/29
709 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
710 GFS to support this as well. Backend handler, bend_srw_update, does the
711 update work. Code contributed by Ko van der Sloot.
713 Allow retrieval of Search Result-1 information in ZOOM by the use of
714 options that are attached to a result set. ZOOM documentation updated
717 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
718 UTF-8 conversion. Patch by Raj Patel.
720 Added option -m to GFS to control formatting of timestamps in log file.
722 Added 'exit' as synonym for 'quit' in yaz-client
724 Added support for specifying SRW resultSetId + resultSetIdleTime in a
725 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
726 for the new members. Patch by Ko van der Sloot.
728 Added support for SRU POST. It is supported for content-type
729 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
731 Do not build the separate Multi-threaded (MT) library libyazthread.la.
732 Instead make the library libyaz.la multi-threaded. Threading as a whole
733 can still be disabled by configure option --disable-threads. Previosly,
734 with older GLIBCs there were problems with MT libs under Apache. This
735 has now been fixed a long time ago.
737 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
740 CQL module modified to be case insensitive for relations/indexes/operations.
742 Fixed bug in CQL transform code: incorrect value relationModifieder
745 Added 'show all' command for yaz-client which retrieves all results
748 Added new yaz-client, xmles, which takes a (private) OID and
749 a document to be sent as an extended service request.
751 Describe new yaz-client commands wait_response and set_auto_wait.
753 Increase TCP/IP listener backlog from 3 (which I am guessing was
754 copied from the SunOS manual entry way back when) so SOMAXCONN, so
755 that the socket will queue as many incoming connections as it's able
756 to handle ongoing connections. In other words, it will never now
757 refuse a connection that it would be able to handle merely because
758 it's not got around to accepting() enough of the pending connections
759 yet. This is the behaviour anyway under Linux, where the listen()
760 argument is ignored; but not under BSD and on systems such as
761 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
762 YAZ-based servers should now be uniform across operating systems in
765 yaz-marcdump uses 64-bit file access on some systems. This is enabled
766 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
767 This allows yaz-marcdump to read large MARC batches (>2 GB).
769 Modified all YAZ source files - except the source which is auto-generated
770 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
773 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
774 corresponding to the existing *_setl() function. These allow option
775 values containing arbitrary valuues.
777 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
778 ZOOM_resultset_sort() in new applications. Its behaviour is identical
779 except that it returns an indicator of whether or not the sort
780 criterion was accepted (0 for OK, -1 for invalid).
784 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
785 MARC output rather than returning "new" buffer.
787 yaz-client warns about unknown init options.
789 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
793 Added support for SRW sort in Generic Frontend Server. Patch
794 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
795 sortKeys - or NULL if none is provided.
797 Fixed bug #307: It was impossible to specify indefinite/no timeout
798 for ZOOM_event. Special timeout value -1 now means indefinite timeout
801 Added support for multiple languages and charsets to be specified in
802 ZOOM. Each charset/language is separated by a blank. If negotiation is
803 in effect in init-response, Option
804 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
805 Code based on patch by Vasiliy Osadchuk.
807 Fixed bug #306: infinite recursion that occurred when calling
808 yaz_log_level_init as the first call (before other log level or
811 Fixed bug in scan handling in front end server: if preferred-Position-In-
812 Response was non-present, a NULL pointer referece was performed.
816 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
817 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
818 now defined for all those error codes. So instead of putting 109 in
819 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
820 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
822 Modified the yaz-marcdump utility to skip garbage bytes between MARC
825 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
827 Program yaz-client now exits and produces an error message if multiple
828 Z39.50 servers are specified on the command line (none or one allowed
831 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
836 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
838 Fixed bug #272: Preserve spacing for CCL terms.
842 Added support for virtual hosts and multiple backend servers for
843 the YAZ frontend server. The configution is XML based and
844 support specificition of CQL to RPN mappings and explain information.
845 See section "Virtual Hosts" in the YAZ manual.
847 Extended OPAC display utility. OPAC display utility renders
848 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
849 to supplement yaz_marc_decode_wrbuf.
851 Fixed a bug in MARC decoder that could caused it to crash for some
852 invalid MARC records. More diagnostics and warnings where added in
853 XML output (warnings, etc are stored in comments).
855 --- 2.0.34 2005/02/08
857 Fixes for UNIX domain sockets. Bug #261.
859 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
861 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
862 Added yaz_marc_subfield_str which defines subfield lead string which is
863 used in YAZ_MARC_LINE format. Default string is blank+$. Added
864 yaz_marc_endline_str which defines end of fields string used in
865 YAZ_MARC_LINE format. Default string is newline.
867 Experimental support for MarcXChange. This format can be produced
868 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
869 http://www.bs.dk/standards/MarcXchange.xsd
871 Added yaz-client commands scansize that sets maximum number of
872 entries to be returned by scan.
874 --- 2.0.32 2005/01/11
876 Added support for SRW scan in yaz-client and Generic Frontend Server.
878 * Added whereInList member to SRW Scan Term.
880 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
882 Fixed NMEM system to return aligned blocks on the smallest boundaries
883 that are suitably aligned for all possible types on the particular
884 architecture YAZ is being built for.
886 --- 2.0.30 2005/01/04
888 Fixed numerious warnings that was issued with newer versions of GCC.
890 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
891 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
894 Make YAZ Generic Frontend Server slightly faster.
896 Enhance (and reduce) logging for Generic Frontend Server.
898 Revert YAZ log system so that it flushes every write operation
899 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
901 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
902 instead of LOG_, due to name clash with syslog(3). LOG_ are still
903 present. New applications should define YAZ_USE_NEW_LOG=1 - this
904 will effectively disable old definitions.
906 --- 2.0.28 2004/11/09
908 Added yaz_log_time_format which specifies log format using
911 Added yaz_log_module_level which returns mask for a module. Value
912 is non-zero mask a if module is enabled; zero if disabled.
914 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
915 in include/yaz/cql.h.
917 Fixed bug #176: Dont throw diagnostics on empty SRU args.
919 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
921 Fixed bug #172: RPM builds does not enable SSL.
923 Doxyfile.in part of dist. Doxyfile generated by configure.
925 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
926 are given and the corresponding component does not exist.
928 Extend CCL documentation in YAZ reference. Describe r=r.
930 --- 2.0.26 2004/10/01
932 Fixed MARC->MARCXML conversion to properly deal with
933 fields, subfields, indicators having non-ASCII characters.
935 Fixed MARC->MARCXML conversion so that ASCII control characters
936 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
939 Added YAZ GFS support for conversion from Z39.50 surrogate
940 diagnostics to SRW surrogate diagnostics.
942 Bug fix: YAZ GFS did not return schema in explainResponse.
944 --- 2.0.25 2004/09/30
946 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
947 now converts recordSchema to elementSetName as well as schema URI.
949 Fixed bug in COMSTACK that prevented HTTP request packages from being
952 --- 2.0.24 2004/09/29
954 Added CCL facility r=r "range" which is similar to r=o "ordered" but
955 does not require white-space before and after the dash in a range, e.g.
956 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
959 Fixed a few AC_TRY_LINK configure tests that did not operate properly
960 due to new GCC removing "redundant" code.
962 Added yaz-client commands scanpos and scanstep that sets preferred
963 position and step-size for scan.
965 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
967 Added CCL utility ccl_qual_buf which parses one or more CCL
968 spec lines in a buffer.
970 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
971 of name and value - ignoring empty lines and comments.
973 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
975 Added odr_get_element_path which returns current element path for an
976 ODR handle. This utility is useful in error handling or user-defined
979 Added ODR_PRINT utility odr_set_stream which is is a more generic
980 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
981 to a write function and pointer to close function. The close function - if
982 non-NULL - will be called during odr_destroy.
984 Fixed bug in CCL parser where truncation char was not removed from
985 right side when truncation=both was in effect.
987 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
990 --- 2.0.23 2004/08/11
992 Fix buffer overrun in CQL parser when dealing with proximity (%).
994 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
995 to UTF-8/UCS conversion is now only based on codetables.xml.
997 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
999 --- 2.0.22 2004/08/06
1001 Add support for more "commit changes" in ZOOM (uses Extended Services).
1003 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1006 Yet another small fix for configure of SSL.
1008 --- 2.0.21 2004/05/14
1010 Fix SSL libs for configure when --with-openssl=DIR is given.
1012 --- 2.0.20 2004/05/10
1014 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1016 SSL comstack now uses yaz.pem certificate file on server side
1017 by default. Certificate filename can be configured by calling
1018 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1020 Fix bug regarding multiple calls to ZOOM_connection_connect.
1022 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1024 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1025 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1027 ZOOM now allows inspection of X509 peer certificate for verification.
1028 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1030 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1031 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1032 as "modular" but it simplifies things.
1034 Added cs_get_peer_certificate to that returns peer X509 PEM.
1036 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1037 NULL if SSL is unavailable.
1039 Documentation about MARC decoding tools.
1041 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1043 --- 2.0.19 2004/03/30
1045 Rename CHANGELOG to NEWS to follow GNU style packing.
1047 Fix bug with missing initialization of member in init_diagnostics.
1048 This bug affects threaded version of GFS server.
1050 --- 2.0.18 2004/03/20
1052 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1055 Ensure zlib.dll is packed with Windows install.
1057 --- 2.0.17 2004/03/17
1059 Fix encoding of xsd:string to use text instead of CDATA.
1061 Fix endless loop in CQL parser with unbalanced ".
1063 Use a more compact way to store MARC-8 conversion tables.
1065 --- 2.0.16 2004/03/16 Debian only
1067 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1070 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1075 --- 2.0.15 2004/03/01
1077 Another fix for decoding of XML packed records.
1079 --- 2.0.14 2004/02/25
1081 Fixes for Chunked encoding. White space not ignored after length spec.
1083 Update NS and use default NS for SRW diagnostic elements.
1085 --- 2.0.13 2004/02/23
1087 Implement ZOOM_resultset_cache_reset which resets record cache.
1089 Implement ZOOM_resultset_sort which sorts a result set.
1091 Implement chunked HTTP transfer.
1093 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1095 --- 2.0.12 2004/02/16
1097 Added member 'schema' to bend_explain_rr structure so that backend
1098 can specify explain record identifier. Defaults to Zeerex 2.0.
1100 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1102 --- 2.0.11 2004/02/16
1104 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1107 Added init command for yaz-client which sends "extra" init request.
1109 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1110 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1112 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1114 Make ZOOM error code for "invalid query".
1116 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1118 --- 2.0.10 2004/02/05
1120 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1123 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1125 Added option -p <file> to make Generic Frontend Server to write PID file.
1127 Added option -D to put Generic Frontend Server in background on its own.
1129 Make ZOOM C recognize option "password". If unset, "pass" is used
1130 (for backwards compatibility).
1132 Fixed a bug in Generic Frontend Server that could make it crash if a
1133 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1136 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1137 Must be issued before open, in order to be in effect.
1139 --- 2.0.9-6 2004/01/12 Debian/Windows
1141 Make the SRU server more picky WRT unknown params, etc.
1143 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1145 New YAZ client command, options, that sets Z39.50 options.
1147 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1148 options from a string of tokens (one token for each option bit).
1150 Update SRW diagnostic code messages.
1152 --- 2.0.9-5 2004/01/07 Debian/Windows
1154 Handle user defined stylesheet for SRW/SRU.
1156 --- 2.0.9-4 2004/01/06 Debian/Windows
1158 Fix bug in decoding of Content-Length.
1160 --- 2.0.9-3 2004/01/06 Debian/Windows
1162 Fix a bug with decoding of XML packed records.
1164 --- 2.0.9-2 2004/01/05 Debian only
1166 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1168 Fix bug in SRW/SRU diagnostics decoding.
1170 --- 2.0.9 2004/01/05
1172 Fixed bug in Generic Frontend Server which could drop records exceeding
1173 preferred message size. Reported and fixed by Irina Dijour.
1175 Fixed calculation of package size for structured records in Generic
1176 Frontend Server. Reported and fixed by Irina Dijour.
1178 Fixed namespace for SRW/SRU diagnostics.
1180 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1182 --- 2.0.8 2003/12/22
1184 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1185 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1188 CQL changes to reflect recent changes to the specification:
1189 * Documentation talks about context sets instead of index sets.
1190 * Documentation talks about indexes instead of qualifiers.
1191 * The CQL-to-PQF transformer's configuration file now uses
1192 "index.set.name = <attributes>" instead of the old form
1193 "qualifier.set.name = <attributes>". (Both forms are still
1194 understood but the latter is deprecated.)
1195 * CQL terms with no explicit index specified are now interpreted as
1196 cql.serverChoice instead of srw.serverChoice (which of course
1197 behaves exactly the same.)
1199 --- 2.0.7 2003/12/16
1201 MARC conversion can now generate ISO2709 output in another
1202 character set. yaz-marcdump uses this facility if you invoke it
1205 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1206 functions from there can be used from C++.
1208 --- 2.0.6 2003/12/04
1210 Frontend server now transfers memory from decoded packages to stream
1213 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1214 references to show up.
1216 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1217 the ZOOM Abstract API. The older names for the same options are still
1218 also supported for the benefit of old applications.
1220 ZOOM-C supports "implementationId" and "implementationVersion" options
1221 to go along with "implementationName". These allow the user code to
1222 specify identification strings to be sent to servers.
1223 Add OID for the new ExtLite attribute set.
1225 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1226 as requested/supplid by Ere Maijala <ere@atp.fi>
1228 For generic frontend server, reverse the order of
1229 "toolkit-supplied / application-supplied" strings sent as implementationId,
1230 Name and Version. Also, remove the spaces around the slash. This brings
1231 the GFS in line with the behaviour of ZOOM-C on the client side.
1233 Add function ZOOM_scanset_display_term.
1235 yaz-client shows scan displayTerm if present.
1237 Utility yaz-iconv is now installed by default along with the man page
1240 Extend configure check for OpenSSL to use pkg-config where available (such
1243 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1244 server to specify uid/gid/mask for socket using the format
1245 unix:[user=uid,][group=gid,][umask=mask,]file=path
1246 If file= is omitted the existing format is assumed, e.g.
1248 in which case the mask is 0666 (rw for everybody).
1250 Major restructure of YAZ source. All source in libyaz is in src directory.
1251 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1252 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1254 Added man page for utility yaz-marcdump (used to be called marcdump).
1255 yaz-marcdump is installed by 'make install'.
1257 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1258 of incoming package failed.
1260 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1262 Change prototype of odr_perror: add const to message string.
1264 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1266 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1267 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1268 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1269 DNS lookup. There should not be any compatibility problems with this
1270 assuming that blocking=1 or 0 is used.
1272 Fix bad reference in UNIX comstack in function cs_addrstr.
1274 Fix for compilation on AIX.
1276 The generic front-end server (server/seshigh.c) now supports returning
1277 Init diagnostics to the client in User-information-field, in
1278 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1281 --- 2.0.4 2003/09/04
1283 Allow any CQL relation (not just all,any,exact,scr).
1285 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1286 that features the same UI.
1288 Implemented command update0 in YAZ client which is equivalent to
1289 update but uses old of Ext Update ASN.1.
1291 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1292 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1293 Previously no OID was used for this info.
1295 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1296 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1297 returns 'malformed search term' otherwise.
1299 SortResponse member resultCount now set to NULL in sort handler of
1302 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1305 Add three new utility functions for translating OIDs between various
1306 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1307 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1308 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1309 char *oid_to_dotstring(const int *oid, char *oidbuf);
1310 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1312 Reverted modifications for ES Update definition for z_IU0Update
1313 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1314 is back to YAZ 2.0.2.
1316 String value attributes for CCL parser.
1318 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1319 which their FirstSearch server returns in Init responses, sometimes
1320 carrying useful diagnostic information when Init fails. This has the
1321 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1322 "z39.50/oclcui.asn", where its definition is somewhat different from
1323 what OCLC document on their web-site, as required to interoperate with
1326 Support for anonymous authentication in yaz-client. Use the command
1329 * Fix the OID of the Index Data-local "admin" Extended Service from
1330 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1331 the 1000, which indicates a locally-defined OID, was a mistake.
1333 --- 2.0.3 2003/06/20
1335 Fix CCL directive @case handling so that it affects string match for
1336 both CCL keywords and qualifiers.
1338 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1339 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1340 Decoder has been updated with ASN.1 changes as listed in
1341 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1342 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1343 z_IUUpdate, remains unchanged.
1345 ZOOM_record_get may now return a record in a specific character set.
1346 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1347 "from" is the character set of record as returned by target. "to" is
1348 the character set to be returned. If omitted, "to" is UTF-8.
1350 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1352 New ODR utility, odr_getelement, which returns name of element for
1353 which encoding/decoding failed.
1355 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1356 in cases where a required element was omitted.
1358 Bug fix: some MARC8 sequences were not converted.
1360 New ZOOM option "step" which specifies number of records to be
1361 retrieved in one chunk. Used in conjunction with "start" and "count".
1363 SRW support for yaz-client. Use scheme http: to use it, e.g.
1366 yaz-client no longer does (un)intelligent character set conversions
1367 by default. Can be enabled with charset and marc_charset commands.
1369 xmalloc trace fix for 64-bit systems such as DEC alpha.
1371 Solaris 2.6 compile fix.
1373 New function, cql_strerror() translates SRW error codes, as returned
1374 by cql_transform_error(), into human-readable English strings. Used
1375 in yaz-client diagnostics when appropriate.
1377 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1378 converts it into a type-1 query which is sent to the server. This
1379 makes CQL available for use with all Z-servers, as opposed to the tiny
1380 minority that can handle CQL queries themselves.
1382 --- 2.0.2 2003/04/28
1384 New Debian package layout similar to the Redhat Package layout.
1386 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1387 and search result respectively.
1389 --- 2.0.1 2003/04/25
1391 Redhat package is now several packages: libyaz (runtime libraries),
1392 libyaz-devel (development and documentation, and yaz (utility programs).
1393 Package spec file by Morten Bøgeskov.
1395 New member 'schema' in struct bend_fetch_rr which the name of requested
1396 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1397 handler MAY set this to reflect the schema of the returned record.
1399 New member 'display_term' in struct scan_entry. GFS now sets member entries
1400 and allocates scan entries to be filled by user scan handler. In previous
1401 version, entries member was allocated by the scan handler. That still works,
1402 but the GFS will ignore member display_term - assuming it was NOT set by
1403 the handler. The fact that the GFS now allocates the entries both allows
1404 for new members and makes a scan handler easier to write.
1406 Fix CQL lex buffer overflow.
1408 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1409 SRU default recordPacking is string.
1411 SRU protocol support for frontend server.
1413 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1415 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1417 Added scan for the ZOOM shell (zoomsh).
1421 * String Identifers for Schemas (Amendment 5).
1422 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1423 Old definition for schema
1424 Odr_oid *schema; /* OPT */
1429 Z_InternationalString *uri;
1430 #define Z_Schema_oid 1
1431 #define Z_Schema_uri 2
1434 * resultCount parameter to Sort Response (Amendment 1).
1435 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1437 Support for SRW 1.0 over HTTP. This is an optional feature and
1438 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1441 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1442 on the same port. SRW SearchRetrieveRequests are mapped
1443 to bend_init,bend_search,bend_fetch,bend_close.
1445 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1447 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1448 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1450 ZOOM connections are SRW based if schem http is used for hostname
1451 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1452 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1454 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1455 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1456 distance=n, order=true/false, relation=le, prox unit=word. If
1457 n is omitted, distance 1 is used.
1459 Fixed problem with C compiler include path in wrong order.
1461 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1462 on Solaris. Patch from Ko van der Sloot.
1464 New MARC decode API. All new functions operate on a yaz_marc_t
1465 handle. The most important new functions are: yaz_marc_create,
1466 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1467 decode and destroy respectively. Decoder can produce formats
1468 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1469 include/yaz/marcdisp.h.
1471 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1472 to UTF-8, UCS-32, wchar_t or Latin-1.
1474 * Prototypes for yaz_iconv_-functions moved to separate header
1475 include/yaz/yaz-iconv.h.
1477 Make a few private functions 'static' in unix.c. This prevents
1478 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1480 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1481 are set when Init Response is received.
1483 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1484 but returns diagnostic set as well.
1486 New function yaz_strerror which is a portable wrapper for
1487 strerror/strerror_r/GetLastMessage.
1489 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1490 is returned for MARC. If type is "oai", then OAI MARC is returned.
1492 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1495 --- 1.9.2 2002/11/26
1497 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1499 Fix bad race conditions on SIGTERM and terminate gracefully in
1502 Move retrieval (data1) module to Zebra since nobody seems to be
1505 Add GRS-1 render for ZOOM using same format as yaz-client.
1507 --- 1.9.1 2002/10/05
1509 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1511 Fix broken ESpec handling in data1 module.
1513 SGML reader parses comments and makes them part of the data1 tree.
1515 Added several type casts so that YAZ compiles as C++ code.
1517 ZOOM didn't handle PDU encoding failures properly.
1519 Added more Bib-1 diagnostics (approved extensions).
1521 GNU configure: better check for iconv.
1523 More portable use of accept, getpeername. Check for socklen_t. Use
1524 int/size_t if socklen_t is not defined.
1528 PQF parser rejects bad queries - including those with extra
1529 characters in them. PQF parser used to silently ignore that.
1530 Cleaner API for PQF added, which allows you to get detailed
1531 error information for bad queries (see yaz/pquery.h).
1533 Fixed bug in ZOOM_record_get for type "database".
1535 Implemented mini iconv library supporting conversions between
1536 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1538 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1540 --- 1.8.9 2002/08/20
1542 Fixed ZOOM C record cache so that preferredRecordSyntax and
1543 elementSetName is used to check for already fetched records.
1545 --- 1.8.8 2002/08/02
1547 Added three members in bend_initrequest structure to facilitate
1548 character set negotiation.
1550 Fixed a bug in frontend server that could cause indefinite
1551 loops under rare conditions.
1553 Revised character set utilities (charneg.h) so that encoding
1554 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1556 For PQF, directive @term <type> sets term type for Scan/Search.
1557 Here <type> is general, string, numeric, null. The term type
1558 is inherited - just like @attr.
1560 New call odr_set_charset that sets character set conversion for
1561 international-strings on a ODR stream. Prototype is:
1562 int odr_set_charset(ODR o, const char *to, const char *from);
1563 The InternationalString is still represented as C string in YAZ
1564 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1565 won't). On the protocol level, you can use any encoding.
1567 Support for UNIX sockets in ZOOM.
1569 Solaris recv sometimes returns errno == ENOENT. It is treated as
1570 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1572 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1573 both client and server. Code by Morten Bøgeskov.
1575 --- 1.8.7 2002/05/22
1577 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1578 that they can be used directly from Visual Basic. You must recompile
1579 your windows APP if you're using ZOOM.
1581 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1582 Commands "lang" and "charset" sets language and character set respectively.
1583 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1584 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1586 Attributes from multiple CCL fields may be OR'ed rather than merged
1587 using directive "@field or". Fields are still merged by default -
1588 equivalent to "@field merge".
1590 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1593 Fixed bug in zget for parameter ExtendedServicesResponse.
1597 --- 1.8.6 2002/03/25
1599 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1601 Client displays USR.1:SearchResult-1 (hits per term).
1603 Additional Search Info for search in Generic Frontend Server.
1605 Fixed CCL parsing of "field=s".
1607 WIN32 installer - using the excellent NSIS software from nullsoft.
1609 Fixed CCL parsing of "field = - <number>".
1611 Added function yaz_marc_decode that decodes MARC for line mode
1612 display or XML (similar to that used by JZKit).
1614 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1615 Z39.50. But ISO/ILL was, however.
1617 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1618 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1620 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1621 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1623 --- 1.8.5 2002/02/03
1625 New YAZ client features: Command completion and new commands:
1626 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1627 Code provided by Jacob Poulsen.
1629 New call oid_trav, that visits all registered OIDs via callback.
1631 Function ZOOM_record_get now returns const char pointer rather than
1632 void pointer. It saves a lot of type casts.
1634 For YAZ client, command "auth" now allows you to set authentication
1635 in IdPass style. It is enabled when three tokens are given - order
1636 is user, group and password.
1638 Fix memory leaks in MARC record handling for ZOOM.
1640 New option for YAZ client, -k <kilobytes> that sets
1641 maximum record size. Similar to -k option for generic frontend
1642 server and yaz-ztest.
1644 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1646 Prefix query parser reports "fail" when bad attribute set is given.
1648 Fix in MARC decoder. Proximity logging. Fix for attribute set
1649 in scan handler for server. Patches by Shigeru Ishida.
1651 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1654 Configure option --with-openssl=<dir> now works when a directory is
1655 specified. Patch provided by Morten Bøgeskov.
1657 New option for YAZ client, -u <auth>, that sets authentication.
1659 ZOOM fix: error information was sometimes "missing", since error
1660 was cleared/reset too when it shouldn't.
1662 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1664 --- 1.8.4 2002/01/04
1666 Scan for ZOOM API. New object ZOOM_scanset. New functions
1667 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1668 ZOOM_scanset_destroy.
1670 New ZOOM function, ZOOM_connection_last_event, that returns type
1671 of last event (such as "receive data", "send data", "apdu received",
1674 New ZOOM option, schema, that specifies schema for retrieval.
1676 New CCL feature. Qualifiers can be aliases for one or more
1677 other qualifiers (if more than one is given, OR is used).
1679 ZOOM uses named result sets if target supports it.
1681 Two new YAZ client commands: . (dot, which sources a script of YAZ
1682 client commands), and ! (to execute shell command.). Implemented
1685 Working on Debian packages.
1687 --- 1.8.3 2001/11/19
1689 YAZ client enables named result sets only if target supports it.
1691 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1693 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1694 with key="host" to get same result.
1696 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1697 Function Z3950_resultset_record(s) returns references to records
1698 "owned" by resultset. To become owner use Z3950_record_clone.
1700 Function z_ext_record handles Extended Services. Thanks to
1703 --- 1.8.2 2001/11/12
1705 CCL Parser fix: ignore token comma when dealing with and-lists.
1707 Documentation updates for COMSTACK.
1709 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1710 Changed prototype Z3950_records. For some functions, int parameters
1711 were changed to size_t.
1713 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1716 New MARC decode/display function, marc_display_exl, which properly rejects
1717 non-ISO2709 records. YAZ client uses it.
1719 --- 1.8.1 2001/10/29
1721 Fix bug: local attribute set wasn't set correctly in PQF strings.
1725 * Old Z39.50 codecs no longer supported.
1727 Added ZOOM C binding. See http://zoom.z3950.org/
1729 Renamed states for COMSTACKs to avoid confusion with events.
1731 Implemented cs_look and proper cs_rcvconnect.
1733 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1735 Configure detects POSIX threads on OpenBSD.
1737 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1738 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1740 When error is returned from present handler, non-surrogate diagnostic
1741 is returned in present response (and fetch handler is no longer called).
1743 * Minor adjustments to pquery parser (PQF). Token characters may be
1744 escaped by using backslash (C-style).
1746 PQF parser allows string attribute values to be specified. For @attr,
1747 non-numeric characters after the equal-sign are treated as strings
1748 (e.g. @attr 9=title).
1750 CCL trunction character may be defined (@truncation in file)
1752 * function zget_ExtendedServicesRequest sets waitAction to
1753 waitIfPossible (was wait).
1755 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1758 CCL operator names may be set in field definition files (CCL_bibset).
1759 See ccl/bib1 for an example.
1761 Fixes in ASN.1 compiler for C++ compatibility.
1763 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1764 and "op_or" to avoid conflict with C++.
1766 Fixed problem with GNU readline detection on Redhat 7.0.
1768 Added step-size for Scan backend handler.
1770 Fixed bug that made the frontend server crash when no attribute
1771 set was specified for scan.
1773 Front-end server automatically switches to original working directory
1774 when installed as an NT service. Previously -w had to be specified to
1777 Added extended attributes for retrieval module (data1), so that data1
1778 records carry d1_readXML/SGML attributes. d1_read also supports
1779 null-data rules ( <tag/>)
1781 On UNIX when POSIX threads are available, a separate library libyazthread
1782 is created. Programmers should link with that library and the yaz library
1783 when using threads. The reason for the split was that some applications
1784 on Linux, such as Apache, doesn't work well when using shared objects that
1787 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1788 (or any frontend server) in SSL mode by specifying ssl: followed by
1789 address. Only tested on UNIX.
1791 Added feature for CCL module. Virtual structure s=al or s=ol generates
1792 and-list and or-list respectively instead of phrase search.
1796 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1797 log_mask_str. This was done to avoid name conflicts with other libraries
1798 (such as other PHP extensions).
1800 Added raw OID member for preferred record syntax (request_format_raw)
1801 and returned record syntax (output_format_raw) for backend fetch method.
1803 Config file yaz-config now accepts options so that it returns specific
1804 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1806 Shared library support for UNIX using GNU libtool.
1808 * Modified backend interface. Request/Response struct's replaced by
1809 one read/write C struct. For example bend_fetchrequest and
1810 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1811 Every handler - even search has to be registered in bend_init
1812 handler. This means that the YAZ library no longer refers to
1813 external functions and it makes it possible to make the whole
1814 thing a single DLL/SO.
1816 Added Segment handler for backend server.
1818 Added Zmbol/Zebra administrative functions to YAZ client.
1820 Threaded frontend server on UNIX (when POSIX Threads are available).
1821 Starting the server with option -T enables multi-threading.
1825 Added configure option --enable-comp/disable-comp to control use
1826 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1827 located in sub directory asn.
1829 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1830 in ${exec_prefix}/bin along with the other programs yaz-client and
1833 GNU automake used to maintain makefiles.
1835 Added several OID's.
1837 Changed retrieval module so that we can load records with no abstract
1838 syntax defined. Tagpaths in these records are fully composed of string
1841 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1845 On UNIX, the generated makefile now supports a proper 'make install'.
1846 The prefix can be set via GNU configure to set the install location
1847 (default is /usr/local).
1849 * YAZ programs client and ztest were renamed to yaz-client and
1850 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1851 locations, such as /usr/bin,/usr/local/bin,etc.
1853 * YAZ Header files were moved from include to include/yaz. YAZ Header
1854 files are referred to as include <yaz/log.h> rather than <log.h>.
1855 The YAZ include path (-I ..) is therefore the same as before. Programmers
1856 should update their #include statements or use -Ipath/include/yaz
1857 instead. The main motivation for doing this change is that YAZ header files
1858 can be installed in "standard" locations /usr/include,/usr/local/include
1859 without introducing conflicts, since ALL YAZ header files are stored
1860 in subdirectory yaz (under /usr/include for example).
1862 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1863 rather than project/workspace files. We switched because project files
1864 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1867 Changed name of logging function, logf, to yaz_log, to prevent name
1868 clash with some math-log functions. The YAZ header log.h defines logf
1869 to yaz_log (#define) so there should be no incompatibilities by this
1872 Added bend_start/bend_stop handlers for server. These handler are
1873 called on start/stop of server. For windows they are called whenever
1874 a service is started/stopped.
1876 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1877 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1878 in util/yc.tcl. The auto-generated C code structures are, in a few
1879 cases, incompatible with the old decoders. There are differences in the
1880 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1881 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1882 The preprocessor variable ASN_COMPILED is defined when the compiled
1883 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1884 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1885 wish to use the old encoders/decoders you can specify --disable-yc
1888 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1889 version so that it supports both new - and old version of DB Update
1891 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1892 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1893 change. The name parameter can be set to 0 in which no name is specified
1894 for the construction. The macros odr_implicit and odr_explicit sets name
1895 parameter to zero for the construction involved. New macros
1896 odr_implicit_tag and odr_explicit_tag are similar to the others,
1897 except that a name parameter is added. For programmers' that don't use
1898 ODR they probably only need to change the call to z_APDU and z_External.
1900 Added access control facility by interfacing the TCP wrapper library.
1901 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1902 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1903 name of the daemon and enables the access control as specified in
1904 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1906 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1907 den Dool <H.M.vdnDool@kub.nl>.
1909 Added reference ID parameter to most functions in server API - refer
1910 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1912 Changed name of ccl library to libccl.a (was ccl.a).
1914 Fixed bug in decoder for Explain (Category TargetInfo).
1916 Added support for GNU readline in client. Thanks to Jacob Poulsen
1917 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1919 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1920 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1921 IMPLEMENTATION! This change was made to the development version before
1922 the ZIG decided to retract the amendment. If any users MUST be
1923 compatible with the original Update definition, PLEASE CONTACT US, and
1924 we will include a separate definition corresponding to the old Update
1925 ES. Note that because of the change to the ASN.1 of the
1926 TaskPackageRecordStructure we cannot define a single structure that
1927 will support both versions.
1929 * Added const modifier to buffer parameter for some ODR/BER encoding
1930 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1931 completeWAIS, odr_dumpBER.
1933 Fixed bug in client.c which caused a crash when a scanResponse didn't
1934 contain positionOfTerm.
1936 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1937 * will cause an error in a client if a non-YAZ target sends both a
1938 * list of Scan entries and non-surrogate diagnostics.
1940 Retrieval module enhancements. Tag sets may be typed in the reference
1941 to it. From the .abs-file the "tagset" directive takes a third optional
1942 integer type for the tag set referenced. From a .tag-file the "include"
1943 directive takes a third optional type as well. The old "type" directive
1944 in the tag set itself is still recognized but acts as the default type
1947 Backend interface change. Individual Scan terms returned from bend_scan
1948 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1949 in include/backend.h.
1951 Retrieval module enhancements. Multiple tag sets and attribute sets may
1952 be specified in abstract syntax specs. Revised the error/warning for
1953 logging messages reported by the retrieval module when reading the
1956 Object Identifier system (oid_..) changed. The API is backwards
1957 compatible but the oid-routines now allocates new OID's when needed.
1958 Raw OID's may be specified in oid_getvalbyname.
1960 YAZ now uses GNU configure to generate Makefile(s).
1962 * Minor changes in some of the member names of DeleteResultSetRequest and
1963 DeleteResultSetResponse. See include/proto.h.
1965 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1966 and added member 'languages' in TargetInfo (which was missing).
1968 Changed the way attribute sets are handled in the retrieval
1969 module. These are now cached, just like the abstract syntaxes
1972 Changed YAZ so that it links with compiled ASN.1.
1974 Added Explain-schema definitions and mapping routines. The following
1975 Explain categories have been implemented: AttributeDetails,
1976 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1978 Fixed minor bug in Windows version of Server Library.
1980 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1982 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1984 Added EXTERNAL: UNIverse Resource Report (non-standard).
1986 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1987 ENUMERATED and SET OF.
1989 * Added 'const' to some of the char pointer arguments for the
1990 functions, data1_read_node, data1_getelementbytagname,
1991 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1994 Fixed bug in data1_insert_taggeddata - the last_child member of
1995 parent wasn't initialised.
1997 * Changed data1_read_record and data1_read_node so that the supplied
1998 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1999 doesn't refer to any parts of the "SGML"-buffer.
2001 Fixed bug in server library (Windows version of statserv_remove).
2003 * Changed code so that it compiles as C++. The type definition
2004 of Odr_fun which is a member of Odr_arm was changed. The result is,
2005 that an explicit typecast is needed for the fun pointer when
2006 using Odr_arm - as in:
2007 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2009 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2011 Implemented the new structured date and time definition as approved
2012 by the ZIG. Added schemaId element to the specificTag in Espec-1
2013 (also approved at the last ZIG). Thanks to RVDM.
2015 Added some Object identifiers (RVDM).
2017 Changed the Update Extended Service (RVDM).
2019 Added command "refid" to client which specifies referenceId for
2020 the following requests.
2022 Implemented extended service handling for server. See ztest.c
2023 for an example as well as backend.h. New handlers are registerd
2024 in the Init handler.
2026 * Changed interface for sort in server.
2028 Added new members to statserv_options_block. It allows a server
2029 to read options from another source than just the command line. Thanks
2030 to Charles Woodfield.
2032 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2033 renamed to zboolean. Some C++ compilers complained about the name.
2035 Minor changes to gils.abs. Added index 's' (sort) on title
2036 and date/time-last-modified.
2038 --- 1.4pl2 1998/1/30
2040 Fixed bug in server library regarding inetd mode (-i). This bug
2041 was introduced by release 1.4.
2043 --- 1.4pl1 1998/1/29
2045 Added sort facility in client and backend server interface.
2047 Fixed problem with dependencies in Makefile(s).
2049 Fixed bugs for encoders/decoders of extended services and
2052 Implemented sub-tree feature for schemas. Sub-trees are
2053 referenced in *.abs-files. See explain.abs for an example
2054 of the use of this feature.
2056 Modified bib1.att; local attributes for ANY didn't include
2057 ANY itself (only affects use of the retrieval module).
2059 Fixed bug in plain SGML reader in function data1_read_node:
2060 tags with prefix "var" was incorrectly interpreted as variants.
2062 Added feature "sub-schemas" to enable references to - and definitions
2063 of - group of elements.
2065 * Removed member parent from type data1_element (in data1.h).
2067 Implemented function odr_nullval() that returns the value of
2070 * Removed member num_children from data1_node (in data1.h).
2072 Made NT service interface part of the server library. The
2073 function statserv_main uses the NT service when required and
2074 calls the statserv_start / statserv_close routines.
2076 Routine zget_SearchRequest and zget_PresentRequest fills
2077 resultSetName/Id member with "default" instead of "Default".
2079 Fixed memory leak in server. Request queue member wasn't freed.
2081 Fixed nmem_exit so that memory is freed.
2085 Revised the CCL parser utility to be thread safe.
2087 Added function, oid_ent_to_oid, to replace the function
2088 oid_getoidbyent, which is not thread safe.
2090 * Added nmem_init and nmem_exit to initialize and release
2091 NMEM resources. Function nmem_init should be called once in the
2092 initial thread before NMEM/ODR is used. statserv.c and client.c
2093 have been changed accordingly. The change was necessary to make
2094 NMEM thread safe. The NMEM memory pool is shared amongst threads
2095 in a process. Unix-based applications will still work fine without
2098 Added NT Services interface for the the Z39.50 (statserv) Server.
2099 Refer to the ztest.c source on the usage.
2101 Windows 95/NT port using MSVC5.0. Project files are included in the
2104 * Defined new 'global' handle for the retrieval (data1) system. The
2105 new handled, data1_handle, describes the state of the data1 system.
2106 This handle is passed as first argument to virtually all
2107 data1 related routines. The functions data1_create and data1_destroy
2108 creates and destroys a data1 handle respectively.
2110 Added ODR encode stream member to all backend request structures
2111 init, search, scan etc. This stream should be used to allocate all
2112 memory used for the response when thread safe operation is needed.
2114 Changed the comstack utility, cs_addstr, to be thread safe. The
2115 returned hostname string returned by the function is now part the
2118 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2119 function. The cs_straddr takes a COMSTACK handle as argument, so this
2120 function must be used after cs_create and before bind/connect.
2121 This function is thread safe.
2123 Moved test server to 'ztest' directory - generic server code still
2124 in 'server' directory.
2126 Made prefix query (pquery.c) utility thread safe.
2128 Added new function modifier YAZ_EXPORT to 'export' public DLL
2129 functions when using windows (see include/yconfig.h).
2131 Added definitions to the OID database (util/oid.c) (RVDM).
2133 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2135 Added call to ccl_rpn_delete in client program.
2137 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2138 release of RPN structure.
2140 Added support for C++, headers uses extern "C" for public definitions.
2141 With input from RVDM.
2143 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2144 Thanks to Ronald van der Meer (RVDM).
2146 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2148 Added support for private extensions to the OID database
2149 (oid_setprivateoids()). Thanks to RVDM.
2151 Added optional, physical ANY (key replication)
2153 Fixed null-reference problem in GRS-1 output filter.
2155 Proximity operator added to Prefix Query Format (PQF).
2157 In test client command "base" accepts multiple databases.
2159 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2163 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2165 Smallish bug-fixes in the new encoders/decoders (explain).
2167 Bug fixed in DeleteRequest.
2169 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2171 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2173 Added SOIF syntax (using private OID for now) to retrieval module and client.
2175 Added Update extended service.
2177 Added SearchResult-1 additional info structure.
2179 Added optional CCL (ISO8777) interpreter as separate module. Available
2182 --- 1.2 1996/6/10 (1st anniversary release)
2184 Added Summary record syntax. Lightly tested.
2186 Added OPAC record syntax. Untested.
2188 Added ResourceReport service encoders/decoders. Untested.
2190 Fixed bug in z_Unit - wrong tagging on unitSystem.
2192 Fixed bug in the DiagRecs decoder.
2194 Added options for max PDU size and session timeout to frontend-server.
2196 Added documentation of query-language parsers and other supporting utilities.
2198 [frontend-server] Added Attribute set to the bend_scanrequest API.
2200 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2201 surrogate diagnostics were generated.
2203 [retrieval] Allow multiple local values for attribute.
2205 [retrieval] Allow multiple attributes per element in .abs files. index type.
2207 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2209 --- 1.1pl2 1996/4/10
2211 Minor changes, mostly specific to Zebra's requirements (retrieval)
2215 Repaired bug in frontend server when running multiple listening
2216 endpoints in dynamic mode.
2218 z_External() now won't break if a known, ASN.1 value comes encapsulated
2219 in an octet-string. The value will pass through unmodified in an Odr_oct.
2221 Added a bit of code to the demo client to decode & display
2222 ASN.1-structured records represented in the octet-aligned branch of
2223 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2225 Added z_ext_getentbyref() to the ASN module. Doc updated.
2227 * Completed the SCAN definition in the ASN module. This may break SCAN
2228 code based on older YAZ-versions at compile-time. The fix is easy -
2231 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2232 under the SCAN definition. Remember to initialize this, server-people.
2234 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2235 that this does not extend to ODR and ASN.
2237 Comstack allows insertion of established socket (primarily for
2238 inetd-operation of servers). Doc updated.
2240 Front-end server can now start from the inetd in TCP mode. Doc
2243 --- 1.0pl4 1996/1/24
2247 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2248 the rank and record number.
2250 Adjustments to the frontend server.
2252 Fixed diagnostic BER dumper. It ignored the file argument.
2256 Various changes to retrieval module.
2258 Changed the union discriminators of the protocol files from enums to
2259 ints paired with #defines.
2261 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2264 *Changed operator in the RPN structure to 'roperator', again to avoid a
2267 Fixed problems in Explain decoders/encoders.
2269 --- 1.0pl2 1995/12/6
2271 Memory bug in log module fixed.
2273 --- 1.0pl1 1995/12/5
2275 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2277 Bug in Explain DatabaseInfo module fixed.
2279 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2283 The shift to v1.0 signals that we now consider the *core* functionality
2284 of YAZ reasonably stable (the core being more or less equivalent to
2285 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2286 tested (Explain not at all - though that will happen soonish).
2288 Minor changes to code to support Windows port.
2290 Various minor changes after we're getting to use GRS-1 & co. more.
2292 Added Espec-1 format.
2294 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2295 of the protocol and it cannot be selected when encoding (maps into 'string'
2296 when decoding). Needed to talk to some servers.
2298 Demo client can request simple element set names.
2300 Added Diagnostic Format encoders/decoders.
2302 Added simple Close handling to frontend server (no hooks for resource
2303 reporting yet), and demonstration client.
2305 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2307 --- 1.0b3 1995/08/24
2309 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2310 handled incorrectly when records were requested in the searchResponse. This
2311 will only affect you if you use the frontend-server.
2313 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2314 Test-client will ask for and print GRS1. Ztest will return dummy records
2317 Added Explain encoders/decoders to the service-level API. Untested.
2319 Added Extended Services: Item Order encoders and decoders to the Service-
2320 level API. Untested. We could use a recent copy of the pertinent bits
2321 of the ILL protocol to add those bits.
2323 Added diagnostic format 1 encoders/decoders to the service-level API.
2326 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2327 odr_cons.c, which causes a more correct output.
2329 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2330 was always set to 0 when no records were requested in the searchRequest.
2332 * Added better external-handling. This shouldn't harm old code that
2333 *encodes* externals. It can break code that looks for a
2334 'single-ASN1-type' representation, since those types that are known
2335 are now decoded immediately. Look at the SUTRS sample code in
2336 seshigh.c and client.c. Documentation updated.
2338 Handling of structured records in bend_fetchresponse. Length -1 marks
2339 structured record, type is deduced from format field.
2341 --- 1.0b2 1995/06/27
2342 Fairly quick maintenance release to add SUTRS support.
2344 Fixed handling of SUTRS records in the demonstration client.
2346 * Added format field to the bend_fetchrequest and bend_fetchresponce
2347 structures of the backend API (frontend server). When the record is
2348 returned, the value of the format field is mapped to an OID. The
2349 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2350 of the record. The special value VAL_NONE in the bend_request means
2351 that no specific format was requested by the client. Documentation
2352 updated accordingly. Test server (ztest) will return a fixed dummy
2353 SUTRS record if your client requests SUTRS.
2355 Documentation updated accordingly.
2357 You can now set external libraries and RANLIB support in the top-level
2361 First public release.
