3 Fixed memory violation that could occur when decoding UTF-8. This bug
4 was only present in 3.0.30 of YAZ.
8 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
9 GNU TLS is used by default (if found).
11 yaz-ztest returns OPAC records if a client asks for OPAC.
13 Improved speed of MARC-8 encoding.
15 Added support for lossy and loss-less MARC-8 encoding.
17 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
19 Added new Windows Service wrapper (sc).
21 yaz-client's itemorder command may now send a file.
23 Fixed yaz-marcdump to allow the use of NS prefix for record element.
25 Added new function yaz_log_xml_errors.
27 Allow (but warn) unknown XML attributes in MARCXML parsing.
29 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
31 The UTF-8 to MARC-8 conversion now uses a different set of characters
32 for Greek symbols. Bug #2120.
36 Added yaz_daemon (daemon.h).
38 Fixed bug #2068: pkg-config trouble
40 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
44 Document --with-xml2 option.
46 Added OPAC XML XSD (etc/opacxml.xsd).
48 Allow glob mask for name attribute in retrieval element for the
49 generic frontend server's retrieval facility.
51 Changed yaz_poll_poll to return yaz_poll_except for all returned events
52 except POLLIN/POLLOUT.
54 Fixed error handling in cs_listen. Bug #2037.
58 Fixed version in yaz/yaz-version.h.
60 Fixed bug #2027: Crash when closing connection.
62 Changed configure so that ICU support is only enabled if only ICU
63 and Libxml2 is available (because the ICU chain is XML based).
67 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
68 is built. Only this DLL depends on the ICU runtime.
70 yaz-ziffy is no longer part of YAZ. It is distributed separately by
71 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
73 Changed license of CCL module to 'Revised BSD'. After consultation with
74 remaining members of the original EUROPAGATE consortium, we are re-issuing
75 the CCL module without a separate license. The software was developed by
76 Index Data as part of a research project. The special license was included
77 to help feed usage information back to the project consortium to support
78 project evaluation. At this time, the project consortium has long-since
79 disbanded, and the majority of the original principals have retired. At the
80 same time, we have significantly modified the software during the following
81 years, to the point where very practically no original code remains. To
82 simplify re-use of the software, we have contacted those members of the
83 consortium who could be reached, and agreed to re-issue the module as a
84 proper part of the YAZ package.
86 Tcl scripts uses /usr/bin/tclsh as preferred shell.
88 CQL closer to being version 1.2 compliant. CQL also allows free-form
89 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
92 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
93 bug could make Extended services handling crash in the ZOOM layer. This
94 bug was only present in YAZ 3.0.18.
98 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
101 yaz-marcdump reads and writes collection wrapped records.
103 Handle OPAC for record conversion module.
105 Fixes for ICU wrapper.
107 Allow ICU libs to be controlled with --with-icu .
109 --- 3.0.16 2007/11/12
111 Added yaz_poll which is a wrapper for select/poll. When poll is available
112 and non-buggy, it is used, by yaz_poll . This allows more than 1024
113 sockets to be in use.
115 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
116 functionality through an XML based configuration (ICU chain). This system
117 is useful for search facilities such as Pazpar2 and Zebra that needs to
118 perform tokenization of indexed material. The ICU code in a separate
119 library libyaz3_icu.a.
121 Added HTTP tunnel facility for COMSTACK, bug #1752.
122 This is a facility that allows a Web proxy, such as squid, to tunnel
123 Z39.50 traffic. This facility is "transparent" to must applications
124 using YAZ. It's enabled by using pseudo transport connect: followed by
125 the proxy address, followed by command, then follwed by he regular
126 "virtual" addresss. For example,
127 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
129 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
131 --- 3.0.14 2007/09/21
133 Fixed bad memory reference in ZOOM_record - cuased by member not being
134 initialized. This was a problem only in YAZ 3.0.12.
136 Fixed bug in conversion from MARC to XML: Non-XML characters in control
137 fields were not removed.
139 Changed the way C code is generated from codetables.xml. Made a MARC-8
140 conversion trie for each characterSet section rather than codeTable.
141 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
142 of codetables.xml from Larry Dixson, LOC. Bug #1464.
144 --- 3.0.12 2007/09/12
146 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
147 from ZOOM_record_error).
149 ZOOM C function ZOOM_record_get returns record schema for type="schema".
151 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
153 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
155 Better SRW-to-Bib-1 diagnostic mapping.
157 ZOOM C and yaz-client announces SRU version 1.2 by default.
159 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
162 Fixed in yaz_sru_decode to allow other version than 1.1.
164 --- 3.0.10 2007/08/22
166 Added support for SRU scan for ZOOM.
168 Added support for the use of the older versions or Extended Service
169 Update in ZOOM. To faciliate this, an option "updateVersion" may be
170 set to the version , 1=first, 2=second, 3=third. The third version is
171 what ZOOM C has used so far. And that, obviously, is the default.
173 Added support for CCL queries in Z39.50 queries sent to the GFS (and
174 therefore in Zebra and in SimpleServer-based applications). The new
175 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
176 qualifier file used to transform incoming CCL queries into Type-1 RPN,
177 which is passed into the back-end search callback function.
179 Added support for HTTP Basic authentication in clients: the SRU/W
180 codec encodes the username/password elements of the PDU structure
181 appropriately, and these may be set using the "user" and "password"
182 options in ZOOM-C applications (the same options that are used for
183 Z39.50 authentication).
187 Fixed bug #1208: SSL appears to be broken in ZOOM.
189 Fixed bug #1206: Libxml2 include path weirdness.
191 Added oid_name_to_dotstring.
193 Allow elementSetName to be specified for ZOOM C record update.
195 Allow waitAction to be specified for ZOOM C based for Extended Services.
197 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
198 syntax OID. Bug introduced in YAZ 3 series.
200 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
204 Fixed bug #1157: yaz-client does not read .yazclientrc from current
205 directory. yaz-client now reads commands from file given by option -f
206 if specified; then tries to read .yazclientrc in current directory.
207 Failing that, it reads .yazclientrc from user's home directory.
209 Added support for correlationInfo Note and ID for Record Update via
212 Added yaz-client command querycharset which specifies character set for
213 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
214 (termListAndStartPoint).
216 Charset ISO5428:1984 is an alias for ISO5428-1984.
218 Implemented a way to perform scan in a result set using Z39.50. This
219 is achieved by attaching the result set name in the characterInfo
220 (type InternationalString) of OtherInformation in the Scan Request PDU.
221 The result set is identified in the otherinformation by the new OID:
222 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
223 This allows for scan in result set and faceted search . Zebra did some
224 of this in the APT term using attribute type 8 and value being result
225 set. Using the OtherInformation approach for this is cleaner and easier
226 to work with in proxies and the like. This facility can be used in
227 yaz-client using new command setscan which takes a result set as first
228 argument, start position (APT) as second.
230 Changed decoding of SRU XML packed records to deal with servers that
231 have recordData with XML data with multiple root nodes. Also make
232 comparison for recordPacking case insensitive. Again, one server
233 returns "XML" where others return "xml".
235 For SRU responses allow Content-Type application/xml as well as text/xml.
239 Fixed bug in character set conversion of BER strings. Bug introduced
244 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
246 For OID class, use oid_class consistently.
248 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
251 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
252 character set for bibliographic information interchange". By Giannis Kosmas.
254 Added documentation on new OID API.
258 Changes to generic frontend server interface: added new member
259 'query_charset' for bend_initrequest structure. A backend init handler
260 should set this member to its native character set for query terms.
261 When defined, the frontend server logic will announce this character set
262 to a client if the negotiationModel bit is set by the client. All server
263 implementors are encouraged to specify this. If a backend server does not
264 specify this a warning is issued using yaz_log(YLOG_WARN,..).
266 Added CCL utility to remove terms (stop words) from resulting RPN
267 tree. This is handled by functions with prefix ccl_stop_words_ .
269 New ZOOM C option, "rpnCharset", which allows client-side conversion of
270 terms in RPN queries.
272 Clean-up the CCL API. Moved some internal structures from ccl.h to
273 private header cclp.h. Changed ccl_parser_create so that a Bibset must
274 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
275 This is replaced by ccl_parser_find_str which takes a string instead.
277 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
278 libyaz.la is the core of YAZ except the generic frontend server and
279 does not depend on POSIX threads anymore. libyaz_server.la is the
280 generic frontend server facilities and uses POSIX thread functionality
281 if available. The libyaz.la no longer depends on POSIX threads because
282 the number of global structures is limited. NMEM no longer re-uses blocks
283 between threads ; it simply free's memory immediately but allocates in
284 "large" chunks as usual. We don't expect any performance penalties
285 because of this. The yaz_log system is still using a global log_level so
286 caution must be taken when modifying it with yaz_log_init_.. +
287 yaz_log_mask_str. This, however, should not cause any trouble because
288 these functions are called during initialization of application code
289 anyway. `yaz-config --libs server` returns libs for server applications;
290 `yaz-config --libs` returns libs for non-server applications.
292 New OID database - with public definitions in oid_db.h. Removed old OID
293 database including the head oid.h and definitions such as enum oid_value
294 and struct oident. The new OID database uses the same string names as
295 before but the 'protocol' is gone. There are now only two representations
296 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
297 converts from string to OID; functions with prefix yaz_oid_to_string
298 converts the other way.
300 Change to emit_term() in CQL-to-PQF query translation: when a term has
301 the /regexp relation modifier, do not process it for leading and
302 trailing "^" and "*", which have quite different meanings in regular
305 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
306 write handlers no longer carries a 'last' parameter. This will make
307 yaz_iconv flush "less" characters. A flush is performed by call to
308 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
310 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
311 removed, because function yaz_query_to_wrbuf does the same.
313 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
314 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
316 Deprecated MARC utility functions removed.
318 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
321 Branch split: YAZ_2_1_55_branch
323 --- 2.1.54 2007/03/16
325 Fix to ZOOM-C so that transparent reconnection is properly handled on
326 connections that are in asynchronous mode.
328 Fixed compilation on OpenBSD 4.0.
330 Large strings in GRS-1 records are now properly displayed in yaz-client.
332 Added character conversion support for "advancegreek"; based on patch from
335 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
336 sequence is met. Before the error was not set so it would be unknown.
338 Adjust yaz-marcdump MARC reader so that it skips until record separator
341 --- 2.1.52 2007/03/07
343 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
344 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
345 fd_set structure used as a bitmask for the FDs to be selected on.
347 Using ACX_PTHREAD macro to check for POSIX threads.
349 Fixed have-vsnprintf check.
351 --- 2.1.50 2007/02/23
353 Fixes for configure on BSD. Bug #900.
355 Added snprintf/vsnprintf wrappers for systems that don't have
356 limits (heavens forbid).
358 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
359 created before all previous tasks were completed and removed from the
360 task queue, the new task could be removed by a mistake.
362 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
364 Implemented pass-through CQL-to-PQF conversions. Bug #861.
366 Fixed bug #832: Problem with MARC/charset in yaz-client.
368 Fixed bug #668: save command line history for yaz-client.
370 Fixed bug #830: pkg-config support.
372 --- 2.1.48 2007/01/23
374 Extended ZOOM result set options with two options that may be read by
375 a client: resultSetStatus and presentStatus with values as specified for
377 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
379 Fixed bug #827: Using SSL fails on Debian etch.
381 Fixed bug #826: Weird looking chars for set of MARC records.
383 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
384 that is treated as an ItemOrder with itemRequest being an XML document
385 external. The value of "doc" is the content.
387 Extended the GFS search facility. New member of bend_search_rr
388 'estimated_hit_count' signals that hits is known to be an estmate
389 (higher or lower than real hit count). New member 'partial_resultset'
390 signals that the search was partial (hit count is lower or equal than
391 real hit count). For Z39.50, the information is stored in resultSetStatus
392 member of SearchResponse APDU. For SRU, the information is signalled
393 via SRU diagnostic 59: "Result set created with valid partial results
396 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
398 --- 2.1.46 2007/01/13
400 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
402 Added ZOOM_connection_peek_event.
404 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
405 the following new functions:
406 ZOOM_event_nonblock, ZOOM_connection_process,
407 ZOOM_connection_get_{socket,mask,timeout},
408 ZOOM_connection_fire_event_{timeout,socket}.
409 The existing blocking event handler, ZOOM_event, is a wrapper for the
410 + blocking ZOOM_event_sys_{poll,select}.
412 Implemented function ccl_xml_config which parses XML version of CCL
413 configuration (bug #798).
415 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
417 Added timings utility (yaz/timing.h)
419 --- 2.1.44 2007/01/03
421 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
424 Fixed bug #779: Rotation of apdu.log fails.
426 Fixed for character set conversions:
427 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
428 Honor G1 set in MARC-8 decoding.
430 --- 2.1.42 2006/12/17
432 Fixed bug #775: char conversion does not handle Alternative UTF-8
435 Implemented function yaz_marc_read_line which parses MARC line format
436 records. There is a wealth of formats out there. So far, this function
437 reads line records produced by yaz_marc_write_line.
439 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
440 more generic and easier to remember(!) options: -i format and -o format
441 which specifies input format and output format respectively - where
442 format is one of "marc", "marcxml", "line", "marcxchange".
444 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
445 does not print anything except warnings for records.
447 For yaz-marcdump, added support for MARC split into files (-s) with a given
450 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
451 spec, at http://www.loc.gov/standards/sru/record-update/
452 This has changed the binary layout of the following structs:
453 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
454 bend_update_rr . Patch by Ko van der Sloot.
456 Added GFS utility function bend_assoc_is_alive which returns 1 if
457 association is still alive (client is connected); 0 otherwise (client
458 closed connection). This allows busy servers to stop working for
461 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
462 been a separate piece of software. This version of ziffy has been modified
463 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
465 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
467 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
468 Client code may now interrogate options such as "init_opt_sort" to
469 find out whether the server claims to support various options.
471 --- 2.1.40 2006/11/27
473 Added utilities yaz_{set,get}_esn to set/get element set name from
476 Removed the build of libyazthread.la. The libyaz.so is the threaded version
477 of YAZ and has been so since YAZ 2.1.10.
479 Implemented ZOOM_record_error which returns error information for
480 record (surrogate diagnostic).
482 --- 2.1.38 2006/10/31
484 Updates for SRU Update by Ko van der Sloot:
485 1. Changed name from "operation" to "action"
486 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
487 versions in the code, marked as 'backward compatible'.
488 3. Added diagnostics for SRU Update.
490 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
492 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
494 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
496 For GFS, fixed problem with SRU diagnostic 'First record position out of
497 range' being issued for 0 hits.
499 zoomtst10 part of Windows Build.
501 --- 2.1.36 2006/10/13
503 Implemented yaz_filepath_comp which splits a path into file path
504 components (required by Zebra 2.0.3+).
506 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
507 BSD inspired license until now so this should not have any real impact on
508 anybody. See http://www.opensource.org/licenses/bsd-license.php
510 Fixed bug #687: Missing log lines.
512 Fixed bug #678: CQL to PQF translation does not preserve double-quote
515 Fixed bug #689: SRU diagnostics to be added.
517 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
518 whether a connection is idle (no more work do do).
520 --- 2.1.34 2006/10/04
522 Change type of optval from long to int for invocation of setsockopt with
523 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
525 Added support for specifying the max log file size for the Generic
526 Frontend Server. The size is given with option -r.
528 --- 2.1.32 2006/09/21
530 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
532 --- 2.1.30 2006/09/17
534 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
537 Fixed bug in Generic Frontend Server that could cause a server to stop
538 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
540 For the generic frontend server, the maximum record size is used as maximum
541 size of incoming packages (SRU + Z39.50). The value until was previously
542 only used in Z39.50 Init negotiation and, later, in a session controlled
543 sizes of records returned. This is controlled using -k option. It can be
544 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
546 --- 2.1.28 2006/09/04
548 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
551 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
553 New option for yaz-marcdump -lpos=value which allows setting a portion
554 of MARC header to a certain value.
556 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
558 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
559 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
561 --- 2.1.26 2006/08/15
563 Fixed problem with SRU mode type (soap, get, post) for yaz-client
566 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
568 --- 2.1.24 2006/08/08
570 Fixed MARC ISO2709 encoding routines to deal with character set
573 Minor changes to GFS logging. Database included in search request log
576 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
577 cached/multiple records.
579 Shared libraries are built by default on Unix+configure.
581 Changed cql2pqf transformation to use a different evaluation order. The
582 new order is: always, relation, structure, position, truncation, index
583 and relationModifier. Old order was: always, relation, relationModifier,
584 structure, index, position, truncation. Note that the the latter ones
585 override former ones for identical attributes.. The new scheme means that
586 it is possible to override any existing attribute with a relationModifier.
587 And also that it is possible to override everything for the index rule
588 (except the ones listed in relationModifier). No order is perfect but this
589 one, we believe, covers more real cases.. The "always" should have been
590 called "default", since the attributes there can be overridden with all
593 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
594 compilation phase, but also for yaz-config --cflags output. This allows
595 us to have public headers with Libxml2 stuff in them . It should also,
596 eventually, make Libxml2 checks redundant in packages using YAZ, such
599 --- 2.1.22 2006/06/15
601 Changed SRU update structure bend_update_rr so that SRU diagnostics are
602 stored in uri, message and details.. Previously diagnostics were stored
603 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
604 compatibility.. but he's probably the only one affected, so.
606 Added support for CCL, compiled on the client side, in ZOOM-C. This
607 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
608 input; the resulting query objects can be used for for searching with
609 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
611 YAZ' configure searches for OpenSSL by default.
613 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
614 SL_CTX_use_certificate_file. See
615 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
616 for more info. Thanks to Ko van der Sloot.
618 --- 2.1.20 2006/06/02
620 Bug #600: SRU GET, POST support for yaz-client. Introduced
621 command 'sru' which selects method SOAP/GET/POST.
623 Allow missingValueAction to be specified for the sortspec string -
624 function yaz_sort_spec. By default, the missing value action is null.
625 Use ! to specify "abort". Use = followed by stringvalue to specify default
628 Ensured that Present-handler (if defined) is called in GFS before any call to
629 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
630 searchRetrieve requests.
632 Documentation for YAZ is now based on the Docbook XML/XSLT using
633 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
634 is no longer depending on jade/openjade or docbook-to-man scripts.
635 PDF is no longer part of the distribution - but can optionally be
636 made using DSSSL/jadetex or FOP.
638 Added retrieval handling support in Generic Frontend Server to support
639 conversion between MARC/XML as well as XSLTtransforms. See
640 etc/yazgfs.xml for an example.
642 Added Authentication support to Generic Frontend Server in SRU
643 mode. Authentication using HTTP Basic is supported, as is the use
644 of 'x-username' and 'x-password' parameters in the request itself.
646 Added support for a new character set MARC8s identical to MARC8 except
647 that it converts combined characters to single Unicode characters in the
648 Latin-1 range (when possible).
650 --- 2.1.18 2006/04/24
652 ASN.1 compiler 0.4: generates brief Doxygen file header for
653 generated .h/.c files.
655 Utility yaz_iconv now supports conversion to MARC-8.
657 New facilities for the MARC module. The reading - and writing of
658 content are separate methods for the yaz_marc_t handle. The following
659 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
660 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
661 format). Write functions have prefix yaz_marc_write_.. The existing
662 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
663 available. Removed support for OAI-MARC and simplexml (not the
664 simplexml from PHP5).
666 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
667 to be returned for this connection.
669 --- 2.1.16 2006/03/31
671 Allow multiple languages and charsets to be specified with
672 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
673 negcharset iso-8859-1,utf-8
675 Translation of proximity nodes from CQL into PQF now works.
677 Moved to automake 1.8, 1.9.
679 Added function yaz_log_set_handler which allows a log handler to be
680 installed. This handler will be called for all log messages. Output
681 to file is also produced; but that can be disabled by passing NULL
682 fname to yaz_log_init_file.
684 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
686 For SRW (including GFS), accept application/soap+xml as content-type
689 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
690 produces NO stylesheet reference even if a default stylesheet is specified
693 --- 2.1.14 2006/03/14
695 Updated Windows package to include yazd.dll + yazd.lib for the
696 Development component.
698 If the environment variable YAZ_LOG is set, then it is used as a
699 string indicating the default level of logging to use if not
700 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
701 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
702 used as before. So, for example, to omit warnings from YAZ logging,
705 cql_transform() now map structure and other attributes before indexes,
706 so that index-specific structures and other attributes can override
707 defaults. So now a combination of mapping specifications such as:
709 index.dc.date = 1=date-modified 4=5
710 does the right thing.
712 cql_transform() now also respects the "always" mapping specification,
713 which establishes an initial set of attributes to be used for all
714 terms except where overridden by more specific attributes associated
715 with the index, relation or modifier.
717 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
718 which mode to use; one of "post", "get" or "soap" (SRW, default).
720 Fixes for yaz_iconv routines: changed trie-based character set conversions
721 to use only non-negative values for bit fields due to Sun's C compiler not
722 supporting negative values.
724 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
725 sequences where not read correctly. Fix by Rustam Usmanov.
727 Updated win/makefile to use options, settings which makes things
728 compile with VS C 2005.
730 --- 2.1.12 2006/02/01
732 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
734 In ZOOM socket code, use select instead of poll on MacOSX.
736 ZOOM-C now support client-side compilation of CQL into RPN that is
737 sent to the server, enabling CQL to be used against all Z39.50
738 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
739 ZOOM_query object, and submit it using ZOOM_connection_search().
740 The CQL-to-RPN translation uses a configuration file, the name of
741 which must be specified in the Connection's "cqlfile" option.
743 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
744 function, which takes as its start-term parameter a ZOOM_query object
745 (which may have had either CQL or RPN set into it).
748 --- 2.1.10 2005/11/29
750 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
751 GFS to support this as well. Backend handler, bend_srw_update, does the
752 update work. Code contributed by Ko van der Sloot.
754 Allow retrieval of Search Result-1 information in ZOOM by the use of
755 options that are attached to a result set. ZOOM documentation updated
758 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
759 UTF-8 conversion. Patch by Raj Patel.
761 Added option -m to GFS to control formatting of timestamps in log file.
763 Added 'exit' as synonym for 'quit' in yaz-client
765 Added support for specifying SRW resultSetId + resultSetIdleTime in a
766 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
767 for the new members. Patch by Ko van der Sloot.
769 Added support for SRU POST. It is supported for content-type
770 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
772 Do not build the separate Multi-threaded (MT) library libyazthread.la.
773 Instead make the library libyaz.la multi-threaded. Threading as a whole
774 can still be disabled by configure option --disable-threads. Previosly,
775 with older GLIBCs there were problems with MT libs under Apache. This
776 has now been fixed a long time ago.
778 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
781 CQL module modified to be case insensitive for relations/indexes/operations.
783 Fixed bug in CQL transform code: incorrect value relationModifieder
786 Added 'show all' command for yaz-client which retrieves all results
789 Added new yaz-client, xmles, which takes a (private) OID and
790 a document to be sent as an extended service request.
792 Describe new yaz-client commands wait_response and set_auto_wait.
794 Increase TCP/IP listener backlog from 3 (which I am guessing was
795 copied from the SunOS manual entry way back when) so SOMAXCONN, so
796 that the socket will queue as many incoming connections as it's able
797 to handle ongoing connections. In other words, it will never now
798 refuse a connection that it would be able to handle merely because
799 it's not got around to accepting() enough of the pending connections
800 yet. This is the behaviour anyway under Linux, where the listen()
801 argument is ignored; but not under BSD and on systems such as
802 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
803 YAZ-based servers should now be uniform across operating systems in
806 yaz-marcdump uses 64-bit file access on some systems. This is enabled
807 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
808 This allows yaz-marcdump to read large MARC batches (>2 GB).
810 Modified all YAZ source files - except the source which is auto-generated
811 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
814 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
815 corresponding to the existing *_setl() function. These allow option
816 values containing arbitrary valuues.
818 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
819 ZOOM_resultset_sort() in new applications. Its behaviour is identical
820 except that it returns an indicator of whether or not the sort
821 criterion was accepted (0 for OK, -1 for invalid).
825 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
826 MARC output rather than returning "new" buffer.
828 yaz-client warns about unknown init options.
830 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
834 Added support for SRW sort in Generic Frontend Server. Patch
835 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
836 sortKeys - or NULL if none is provided.
838 Fixed bug #307: It was impossible to specify indefinite/no timeout
839 for ZOOM_event. Special timeout value -1 now means indefinite timeout
842 Added support for multiple languages and charsets to be specified in
843 ZOOM. Each charset/language is separated by a blank. If negotiation is
844 in effect in init-response, Option
845 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
846 Code based on patch by Vasiliy Osadchuk.
848 Fixed bug #306: infinite recursion that occurred when calling
849 yaz_log_level_init as the first call (before other log level or
852 Fixed bug in scan handling in front end server: if preferred-Position-In-
853 Response was non-present, a NULL pointer referece was performed.
857 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
858 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
859 now defined for all those error codes. So instead of putting 109 in
860 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
861 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
863 Modified the yaz-marcdump utility to skip garbage bytes between MARC
866 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
868 Program yaz-client now exits and produces an error message if multiple
869 Z39.50 servers are specified on the command line (none or one allowed
872 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
877 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
879 Fixed bug #272: Preserve spacing for CCL terms.
883 Added support for virtual hosts and multiple backend servers for
884 the YAZ frontend server. The configution is XML based and
885 support specificition of CQL to RPN mappings and explain information.
886 See section "Virtual Hosts" in the YAZ manual.
888 Extended OPAC display utility. OPAC display utility renders
889 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
890 to supplement yaz_marc_decode_wrbuf.
892 Fixed a bug in MARC decoder that could caused it to crash for some
893 invalid MARC records. More diagnostics and warnings where added in
894 XML output (warnings, etc are stored in comments).
896 --- 2.0.34 2005/02/08
898 Fixes for UNIX domain sockets. Bug #261.
900 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
902 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
903 Added yaz_marc_subfield_str which defines subfield lead string which is
904 used in YAZ_MARC_LINE format. Default string is blank+$. Added
905 yaz_marc_endline_str which defines end of fields string used in
906 YAZ_MARC_LINE format. Default string is newline.
908 Experimental support for MarcXChange. This format can be produced
909 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
910 http://www.bs.dk/standards/MarcXchange.xsd
912 Added yaz-client commands scansize that sets maximum number of
913 entries to be returned by scan.
915 --- 2.0.32 2005/01/11
917 Added support for SRW scan in yaz-client and Generic Frontend Server.
919 * Added whereInList member to SRW Scan Term.
921 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
923 Fixed NMEM system to return aligned blocks on the smallest boundaries
924 that are suitably aligned for all possible types on the particular
925 architecture YAZ is being built for.
927 --- 2.0.30 2005/01/04
929 Fixed numerious warnings that was issued with newer versions of GCC.
931 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
932 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
935 Make YAZ Generic Frontend Server slightly faster.
937 Enhance (and reduce) logging for Generic Frontend Server.
939 Revert YAZ log system so that it flushes every write operation
940 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
942 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
943 instead of LOG_, due to name clash with syslog(3). LOG_ are still
944 present. New applications should define YAZ_USE_NEW_LOG=1 - this
945 will effectively disable old definitions.
947 --- 2.0.28 2004/11/09
949 Added yaz_log_time_format which specifies log format using
952 Added yaz_log_module_level which returns mask for a module. Value
953 is non-zero mask a if module is enabled; zero if disabled.
955 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
956 in include/yaz/cql.h.
958 Fixed bug #176: Dont throw diagnostics on empty SRU args.
960 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
962 Fixed bug #172: RPM builds does not enable SSL.
964 Doxyfile.in part of dist. Doxyfile generated by configure.
966 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
967 are given and the corresponding component does not exist.
969 Extend CCL documentation in YAZ reference. Describe r=r.
971 --- 2.0.26 2004/10/01
973 Fixed MARC->MARCXML conversion to properly deal with
974 fields, subfields, indicators having non-ASCII characters.
976 Fixed MARC->MARCXML conversion so that ASCII control characters
977 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
980 Added YAZ GFS support for conversion from Z39.50 surrogate
981 diagnostics to SRW surrogate diagnostics.
983 Bug fix: YAZ GFS did not return schema in explainResponse.
985 --- 2.0.25 2004/09/30
987 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
988 now converts recordSchema to elementSetName as well as schema URI.
990 Fixed bug in COMSTACK that prevented HTTP request packages from being
993 --- 2.0.24 2004/09/29
995 Added CCL facility r=r "range" which is similar to r=o "ordered" but
996 does not require white-space before and after the dash in a range, e.g.
997 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1000 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1001 due to new GCC removing "redundant" code.
1003 Added yaz-client commands scanpos and scanstep that sets preferred
1004 position and step-size for scan.
1006 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1008 Added CCL utility ccl_qual_buf which parses one or more CCL
1009 spec lines in a buffer.
1011 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1012 of name and value - ignoring empty lines and comments.
1014 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1016 Added odr_get_element_path which returns current element path for an
1017 ODR handle. This utility is useful in error handling or user-defined
1020 Added ODR_PRINT utility odr_set_stream which is is a more generic
1021 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1022 to a write function and pointer to close function. The close function - if
1023 non-NULL - will be called during odr_destroy.
1025 Fixed bug in CCL parser where truncation char was not removed from
1026 right side when truncation=both was in effect.
1028 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1031 --- 2.0.23 2004/08/11
1033 Fix buffer overrun in CQL parser when dealing with proximity (%).
1035 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1036 to UTF-8/UCS conversion is now only based on codetables.xml.
1038 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1040 --- 2.0.22 2004/08/06
1042 Add support for more "commit changes" in ZOOM (uses Extended Services).
1044 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1047 Yet another small fix for configure of SSL.
1049 --- 2.0.21 2004/05/14
1051 Fix SSL libs for configure when --with-openssl=DIR is given.
1053 --- 2.0.20 2004/05/10
1055 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1057 SSL comstack now uses yaz.pem certificate file on server side
1058 by default. Certificate filename can be configured by calling
1059 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1061 Fix bug regarding multiple calls to ZOOM_connection_connect.
1063 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1065 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1066 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1068 ZOOM now allows inspection of X509 peer certificate for verification.
1069 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1071 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1072 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1073 as "modular" but it simplifies things.
1075 Added cs_get_peer_certificate to that returns peer X509 PEM.
1077 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1078 NULL if SSL is unavailable.
1080 Documentation about MARC decoding tools.
1082 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1084 --- 2.0.19 2004/03/30
1086 Rename CHANGELOG to NEWS to follow GNU style packing.
1088 Fix bug with missing initialization of member in init_diagnostics.
1089 This bug affects threaded version of GFS server.
1091 --- 2.0.18 2004/03/20
1093 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1096 Ensure zlib.dll is packed with Windows install.
1098 --- 2.0.17 2004/03/17
1100 Fix encoding of xsd:string to use text instead of CDATA.
1102 Fix endless loop in CQL parser with unbalanced ".
1104 Use a more compact way to store MARC-8 conversion tables.
1106 --- 2.0.16 2004/03/16 Debian only
1108 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1111 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1116 --- 2.0.15 2004/03/01
1118 Another fix for decoding of XML packed records.
1120 --- 2.0.14 2004/02/25
1122 Fixes for Chunked encoding. White space not ignored after length spec.
1124 Update NS and use default NS for SRW diagnostic elements.
1126 --- 2.0.13 2004/02/23
1128 Implement ZOOM_resultset_cache_reset which resets record cache.
1130 Implement ZOOM_resultset_sort which sorts a result set.
1132 Implement chunked HTTP transfer.
1134 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1136 --- 2.0.12 2004/02/16
1138 Added member 'schema' to bend_explain_rr structure so that backend
1139 can specify explain record identifier. Defaults to Zeerex 2.0.
1141 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1143 --- 2.0.11 2004/02/16
1145 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1148 Added init command for yaz-client which sends "extra" init request.
1150 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1151 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1153 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1155 Make ZOOM error code for "invalid query".
1157 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1159 --- 2.0.10 2004/02/05
1161 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1164 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1166 Added option -p <file> to make Generic Frontend Server to write PID file.
1168 Added option -D to put Generic Frontend Server in background on its own.
1170 Make ZOOM C recognize option "password". If unset, "pass" is used
1171 (for backwards compatibility).
1173 Fixed a bug in Generic Frontend Server that could make it crash if a
1174 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1177 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1178 Must be issued before open, in order to be in effect.
1180 --- 2.0.9-6 2004/01/12 Debian/Windows
1182 Make the SRU server more picky WRT unknown params, etc.
1184 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1186 New YAZ client command, options, that sets Z39.50 options.
1188 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1189 options from a string of tokens (one token for each option bit).
1191 Update SRW diagnostic code messages.
1193 --- 2.0.9-5 2004/01/07 Debian/Windows
1195 Handle user defined stylesheet for SRW/SRU.
1197 --- 2.0.9-4 2004/01/06 Debian/Windows
1199 Fix bug in decoding of Content-Length.
1201 --- 2.0.9-3 2004/01/06 Debian/Windows
1203 Fix a bug with decoding of XML packed records.
1205 --- 2.0.9-2 2004/01/05 Debian only
1207 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1209 Fix bug in SRW/SRU diagnostics decoding.
1211 --- 2.0.9 2004/01/05
1213 Fixed bug in Generic Frontend Server which could drop records exceeding
1214 preferred message size. Reported and fixed by Irina Dijour.
1216 Fixed calculation of package size for structured records in Generic
1217 Frontend Server. Reported and fixed by Irina Dijour.
1219 Fixed namespace for SRW/SRU diagnostics.
1221 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1223 --- 2.0.8 2003/12/22
1225 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1226 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1229 CQL changes to reflect recent changes to the specification:
1230 * Documentation talks about context sets instead of index sets.
1231 * Documentation talks about indexes instead of qualifiers.
1232 * The CQL-to-PQF transformer's configuration file now uses
1233 "index.set.name = <attributes>" instead of the old form
1234 "qualifier.set.name = <attributes>". (Both forms are still
1235 understood but the latter is deprecated.)
1236 * CQL terms with no explicit index specified are now interpreted as
1237 cql.serverChoice instead of srw.serverChoice (which of course
1238 behaves exactly the same.)
1240 --- 2.0.7 2003/12/16
1242 MARC conversion can now generate ISO2709 output in another
1243 character set. yaz-marcdump uses this facility if you invoke it
1246 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1247 functions from there can be used from C++.
1249 --- 2.0.6 2003/12/04
1251 Frontend server now transfers memory from decoded packages to stream
1254 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1255 references to show up.
1257 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1258 the ZOOM Abstract API. The older names for the same options are still
1259 also supported for the benefit of old applications.
1261 ZOOM-C supports "implementationId" and "implementationVersion" options
1262 to go along with "implementationName". These allow the user code to
1263 specify identification strings to be sent to servers.
1264 Add OID for the new ExtLite attribute set.
1266 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1267 as requested/supplid by Ere Maijala <ere@atp.fi>
1269 For generic frontend server, reverse the order of
1270 "toolkit-supplied / application-supplied" strings sent as implementationId,
1271 Name and Version. Also, remove the spaces around the slash. This brings
1272 the GFS in line with the behaviour of ZOOM-C on the client side.
1274 Add function ZOOM_scanset_display_term.
1276 yaz-client shows scan displayTerm if present.
1278 Utility yaz-iconv is now installed by default along with the man page
1281 Extend configure check for OpenSSL to use pkg-config where available (such
1284 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1285 server to specify uid/gid/mask for socket using the format
1286 unix:[user=uid,][group=gid,][umask=mask,]file=path
1287 If file= is omitted the existing format is assumed, e.g.
1289 in which case the mask is 0666 (rw for everybody).
1291 Major restructure of YAZ source. All source in libyaz is in src directory.
1292 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1293 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1295 Added man page for utility yaz-marcdump (used to be called marcdump).
1296 yaz-marcdump is installed by 'make install'.
1298 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1299 of incoming package failed.
1301 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1303 Change prototype of odr_perror: add const to message string.
1305 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1307 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1308 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1309 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1310 DNS lookup. There should not be any compatibility problems with this
1311 assuming that blocking=1 or 0 is used.
1313 Fix bad reference in UNIX comstack in function cs_addrstr.
1315 Fix for compilation on AIX.
1317 The generic front-end server (server/seshigh.c) now supports returning
1318 Init diagnostics to the client in User-information-field, in
1319 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1322 --- 2.0.4 2003/09/04
1324 Allow any CQL relation (not just all,any,exact,scr).
1326 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1327 that features the same UI.
1329 Implemented command update0 in YAZ client which is equivalent to
1330 update but uses old of Ext Update ASN.1.
1332 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1333 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1334 Previously no OID was used for this info.
1336 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1337 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1338 returns 'malformed search term' otherwise.
1340 SortResponse member resultCount now set to NULL in sort handler of
1343 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1346 Add three new utility functions for translating OIDs between various
1347 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1348 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1349 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1350 char *oid_to_dotstring(const int *oid, char *oidbuf);
1351 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1353 Reverted modifications for ES Update definition for z_IU0Update
1354 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1355 is back to YAZ 2.0.2.
1357 String value attributes for CCL parser.
1359 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1360 which their FirstSearch server returns in Init responses, sometimes
1361 carrying useful diagnostic information when Init fails. This has the
1362 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1363 "z39.50/oclcui.asn", where its definition is somewhat different from
1364 what OCLC document on their web-site, as required to interoperate with
1367 Support for anonymous authentication in yaz-client. Use the command
1370 * Fix the OID of the Index Data-local "admin" Extended Service from
1371 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1372 the 1000, which indicates a locally-defined OID, was a mistake.
1374 --- 2.0.3 2003/06/20
1376 Fix CCL directive @case handling so that it affects string match for
1377 both CCL keywords and qualifiers.
1379 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1380 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1381 Decoder has been updated with ASN.1 changes as listed in
1382 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1383 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1384 z_IUUpdate, remains unchanged.
1386 ZOOM_record_get may now return a record in a specific character set.
1387 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1388 "from" is the character set of record as returned by target. "to" is
1389 the character set to be returned. If omitted, "to" is UTF-8.
1391 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1393 New ODR utility, odr_getelement, which returns name of element for
1394 which encoding/decoding failed.
1396 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1397 in cases where a required element was omitted.
1399 Bug fix: some MARC8 sequences were not converted.
1401 New ZOOM option "step" which specifies number of records to be
1402 retrieved in one chunk. Used in conjunction with "start" and "count".
1404 SRW support for yaz-client. Use scheme http: to use it, e.g.
1407 yaz-client no longer does (un)intelligent character set conversions
1408 by default. Can be enabled with charset and marc_charset commands.
1410 xmalloc trace fix for 64-bit systems such as DEC alpha.
1412 Solaris 2.6 compile fix.
1414 New function, cql_strerror() translates SRW error codes, as returned
1415 by cql_transform_error(), into human-readable English strings. Used
1416 in yaz-client diagnostics when appropriate.
1418 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1419 converts it into a type-1 query which is sent to the server. This
1420 makes CQL available for use with all Z-servers, as opposed to the tiny
1421 minority that can handle CQL queries themselves.
1423 --- 2.0.2 2003/04/28
1425 New Debian package layout similar to the Redhat Package layout.
1427 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1428 and search result respectively.
1430 --- 2.0.1 2003/04/25
1432 Redhat package is now several packages: libyaz (runtime libraries),
1433 libyaz-devel (development and documentation, and yaz (utility programs).
1434 Package spec file by Morten Bogeskov.
1436 New member 'schema' in struct bend_fetch_rr which the name of requested
1437 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1438 handler MAY set this to reflect the schema of the returned record.
1440 New member 'display_term' in struct scan_entry. GFS now sets member entries
1441 and allocates scan entries to be filled by user scan handler. In previous
1442 version, entries member was allocated by the scan handler. That still works,
1443 but the GFS will ignore member display_term - assuming it was NOT set by
1444 the handler. The fact that the GFS now allocates the entries both allows
1445 for new members and makes a scan handler easier to write.
1447 Fix CQL lex buffer overflow.
1449 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1450 SRU default recordPacking is string.
1452 SRU protocol support for frontend server.
1454 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1456 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1458 Added scan for the ZOOM shell (zoomsh).
1462 * String Identifers for Schemas (Amendment 5).
1463 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1464 Old definition for schema
1465 Odr_oid *schema; /* OPT */
1470 Z_InternationalString *uri;
1471 #define Z_Schema_oid 1
1472 #define Z_Schema_uri 2
1475 * resultCount parameter to Sort Response (Amendment 1).
1476 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1478 Support for SRW 1.0 over HTTP. This is an optional feature and
1479 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1482 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1483 on the same port. SRW SearchRetrieveRequests are mapped
1484 to bend_init,bend_search,bend_fetch,bend_close.
1486 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1488 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1489 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1491 ZOOM connections are SRW based if schem http is used for hostname
1492 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1493 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1495 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1496 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1497 distance=n, order=true/false, relation=le, prox unit=word. If
1498 n is omitted, distance 1 is used.
1500 Fixed problem with C compiler include path in wrong order.
1502 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1503 on Solaris. Patch from Ko van der Sloot.
1505 New MARC decode API. All new functions operate on a yaz_marc_t
1506 handle. The most important new functions are: yaz_marc_create,
1507 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1508 decode and destroy respectively. Decoder can produce formats
1509 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1510 include/yaz/marcdisp.h.
1512 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1513 to UTF-8, UCS-32, wchar_t or Latin-1.
1515 * Prototypes for yaz_iconv_-functions moved to separate header
1516 include/yaz/yaz-iconv.h.
1518 Make a few private functions 'static' in unix.c. This prevents
1519 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1521 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1522 are set when Init Response is received.
1524 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1525 but returns diagnostic set as well.
1527 New function yaz_strerror which is a portable wrapper for
1528 strerror/strerror_r/GetLastMessage.
1530 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1531 is returned for MARC. If type is "oai", then OAI MARC is returned.
1533 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1536 --- 1.9.2 2002/11/26
1538 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1540 Fix bad race conditions on SIGTERM and terminate gracefully in
1543 Move retrieval (data1) module to Zebra since nobody seems to be
1546 Add GRS-1 render for ZOOM using same format as yaz-client.
1548 --- 1.9.1 2002/10/05
1550 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1552 Fix broken ESpec handling in data1 module.
1554 SGML reader parses comments and makes them part of the data1 tree.
1556 Added several type casts so that YAZ compiles as C++ code.
1558 ZOOM didn't handle PDU encoding failures properly.
1560 Added more Bib-1 diagnostics (approved extensions).
1562 GNU configure: better check for iconv.
1564 More portable use of accept, getpeername. Check for socklen_t. Use
1565 int/size_t if socklen_t is not defined.
1569 PQF parser rejects bad queries - including those with extra
1570 characters in them. PQF parser used to silently ignore that.
1571 Cleaner API for PQF added, which allows you to get detailed
1572 error information for bad queries (see yaz/pquery.h).
1574 Fixed bug in ZOOM_record_get for type "database".
1576 Implemented mini iconv library supporting conversions between
1577 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1579 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1581 --- 1.8.9 2002/08/20
1583 Fixed ZOOM C record cache so that preferredRecordSyntax and
1584 elementSetName is used to check for already fetched records.
1586 --- 1.8.8 2002/08/02
1588 Added three members in bend_initrequest structure to facilitate
1589 character set negotiation.
1591 Fixed a bug in frontend server that could cause indefinite
1592 loops under rare conditions.
1594 Revised character set utilities (charneg.h) so that encoding
1595 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1597 For PQF, directive @term <type> sets term type for Scan/Search.
1598 Here <type> is general, string, numeric, null. The term type
1599 is inherited - just like @attr.
1601 New call odr_set_charset that sets character set conversion for
1602 international-strings on a ODR stream. Prototype is:
1603 int odr_set_charset(ODR o, const char *to, const char *from);
1604 The InternationalString is still represented as C string in YAZ
1605 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1606 won't). On the protocol level, you can use any encoding.
1608 Support for UNIX sockets in ZOOM.
1610 Solaris recv sometimes returns errno == ENOENT. It is treated as
1611 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1613 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1614 both client and server. Code by Morten Bogeskov.
1616 --- 1.8.7 2002/05/22
1618 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1619 that they can be used directly from Visual Basic. You must recompile
1620 your windows APP if you're using ZOOM.
1622 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1623 Commands "lang" and "charset" sets language and character set respectively.
1624 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1625 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1627 Attributes from multiple CCL fields may be OR'ed rather than merged
1628 using directive "@field or". Fields are still merged by default -
1629 equivalent to "@field merge".
1631 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1634 Fixed bug in zget for parameter ExtendedServicesResponse.
1638 --- 1.8.6 2002/03/25
1640 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1642 Client displays USR.1:SearchResult-1 (hits per term).
1644 Additional Search Info for search in Generic Frontend Server.
1646 Fixed CCL parsing of "field=s".
1648 WIN32 installer - using the excellent NSIS software from nullsoft.
1650 Fixed CCL parsing of "field = - <number>".
1652 Added function yaz_marc_decode that decodes MARC for line mode
1653 display or XML (similar to that used by JZKit).
1655 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1656 Z39.50. But ISO/ILL was, however.
1658 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1659 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1661 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1662 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1664 --- 1.8.5 2002/02/03
1666 New YAZ client features: Command completion and new commands:
1667 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1668 Code provided by Jacob Poulsen.
1670 New call oid_trav, that visits all registered OIDs via callback.
1672 Function ZOOM_record_get now returns const char pointer rather than
1673 void pointer. It saves a lot of type casts.
1675 For YAZ client, command "auth" now allows you to set authentication
1676 in IdPass style. It is enabled when three tokens are given - order
1677 is user, group and password.
1679 Fix memory leaks in MARC record handling for ZOOM.
1681 New option for YAZ client, -k <kilobytes> that sets
1682 maximum record size. Similar to -k option for generic frontend
1683 server and yaz-ztest.
1685 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1687 Prefix query parser reports "fail" when bad attribute set is given.
1689 Fix in MARC decoder. Proximity logging. Fix for attribute set
1690 in scan handler for server. Patches by Shigeru Ishida.
1692 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1695 Configure option --with-openssl=<dir> now works when a directory is
1696 specified. Patch provided by Morten Bogeskov.
1698 New option for YAZ client, -u <auth>, that sets authentication.
1700 ZOOM fix: error information was sometimes "missing", since error
1701 was cleared/reset too when it shouldn't.
1703 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1705 --- 1.8.4 2002/01/04
1707 Scan for ZOOM API. New object ZOOM_scanset. New functions
1708 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1709 ZOOM_scanset_destroy.
1711 New ZOOM function, ZOOM_connection_last_event, that returns type
1712 of last event (such as "receive data", "send data", "apdu received",
1715 New ZOOM option, schema, that specifies schema for retrieval.
1717 New CCL feature. Qualifiers can be aliases for one or more
1718 other qualifiers (if more than one is given, OR is used).
1720 ZOOM uses named result sets if target supports it.
1722 Two new YAZ client commands: . (dot, which sources a script of YAZ
1723 client commands), and ! (to execute shell command.). Implemented
1726 Working on Debian packages.
1728 --- 1.8.3 2001/11/19
1730 YAZ client enables named result sets only if target supports it.
1732 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1734 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1735 with key="host" to get same result.
1737 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1738 Function Z3950_resultset_record(s) returns references to records
1739 "owned" by resultset. To become owner use Z3950_record_clone.
1741 Function z_ext_record handles Extended Services. Thanks to
1744 --- 1.8.2 2001/11/12
1746 CCL Parser fix: ignore token comma when dealing with and-lists.
1748 Documentation updates for COMSTACK.
1750 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1751 Changed prototype Z3950_records. For some functions, int parameters
1752 were changed to size_t.
1754 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1757 New MARC decode/display function, marc_display_exl, which properly rejects
1758 non-ISO2709 records. YAZ client uses it.
1760 --- 1.8.1 2001/10/29
1762 Fix bug: local attribute set wasn't set correctly in PQF strings.
1766 * Old Z39.50 codecs no longer supported.
1768 Added ZOOM C binding. See http://zoom.z3950.org/
1770 Renamed states for COMSTACKs to avoid confusion with events.
1772 Implemented cs_look and proper cs_rcvconnect.
1774 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1776 Configure detects POSIX threads on OpenBSD.
1778 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1779 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1781 When error is returned from present handler, non-surrogate diagnostic
1782 is returned in present response (and fetch handler is no longer called).
1784 * Minor adjustments to pquery parser (PQF). Token characters may be
1785 escaped by using backslash (C-style).
1787 PQF parser allows string attribute values to be specified. For @attr,
1788 non-numeric characters after the equal-sign are treated as strings
1789 (e.g. @attr 9=title).
1791 CCL trunction character may be defined (@truncation in file)
1793 * function zget_ExtendedServicesRequest sets waitAction to
1794 waitIfPossible (was wait).
1796 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1799 CCL operator names may be set in field definition files (CCL_bibset).
1800 See ccl/bib1 for an example.
1802 Fixes in ASN.1 compiler for C++ compatibility.
1804 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1805 and "op_or" to avoid conflict with C++.
1807 Fixed problem with GNU readline detection on Redhat 7.0.
1809 Added step-size for Scan backend handler.
1811 Fixed bug that made the frontend server crash when no attribute
1812 set was specified for scan.
1814 Front-end server automatically switches to original working directory
1815 when installed as an NT service. Previously -w had to be specified to
1818 Added extended attributes for retrieval module (data1), so that data1
1819 records carry d1_readXML/SGML attributes. d1_read also supports
1820 null-data rules ( <tag/>)
1822 On UNIX when POSIX threads are available, a separate library libyazthread
1823 is created. Programmers should link with that library and the yaz library
1824 when using threads. The reason for the split was that some applications
1825 on Linux, such as Apache, doesn't work well when using shared objects that
1828 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1829 (or any frontend server) in SSL mode by specifying ssl: followed by
1830 address. Only tested on UNIX.
1832 Added feature for CCL module. Virtual structure s=al or s=ol generates
1833 and-list and or-list respectively instead of phrase search.
1837 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1838 log_mask_str. This was done to avoid name conflicts with other libraries
1839 (such as other PHP extensions).
1841 Added raw OID member for preferred record syntax (request_format_raw)
1842 and returned record syntax (output_format_raw) for backend fetch method.
1844 Config file yaz-config now accepts options so that it returns specific
1845 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1847 Shared library support for UNIX using GNU libtool.
1849 * Modified backend interface. Request/Response struct's replaced by
1850 one read/write C struct. For example bend_fetchrequest and
1851 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1852 Every handler - even search has to be registered in bend_init
1853 handler. This means that the YAZ library no longer refers to
1854 external functions and it makes it possible to make the whole
1855 thing a single DLL/SO.
1857 Added Segment handler for backend server.
1859 Added Zmbol/Zebra administrative functions to YAZ client.
1861 Threaded frontend server on UNIX (when POSIX Threads are available).
1862 Starting the server with option -T enables multi-threading.
1866 Added configure option --enable-comp/disable-comp to control use
1867 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1868 located in sub directory asn.
1870 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1871 in ${exec_prefix}/bin along with the other programs yaz-client and
1874 GNU automake used to maintain makefiles.
1876 Added several OID's.
1878 Changed retrieval module so that we can load records with no abstract
1879 syntax defined. Tagpaths in these records are fully composed of string
1882 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1886 On UNIX, the generated makefile now supports a proper 'make install'.
1887 The prefix can be set via GNU configure to set the install location
1888 (default is /usr/local).
1890 * YAZ programs client and ztest were renamed to yaz-client and
1891 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1892 locations, such as /usr/bin,/usr/local/bin,etc.
1894 * YAZ Header files were moved from include to include/yaz. YAZ Header
1895 files are referred to as include <yaz/log.h> rather than <log.h>.
1896 The YAZ include path (-I ..) is therefore the same as before. Programmers
1897 should update their #include statements or use -Ipath/include/yaz
1898 instead. The main motivation for doing this change is that YAZ header files
1899 can be installed in "standard" locations /usr/include,/usr/local/include
1900 without introducing conflicts, since ALL YAZ header files are stored
1901 in subdirectory yaz (under /usr/include for example).
1903 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1904 rather than project/workspace files. We switched because project files
1905 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1908 Changed name of logging function, logf, to yaz_log, to prevent name
1909 clash with some math-log functions. The YAZ header log.h defines logf
1910 to yaz_log (#define) so there should be no incompatibilities by this
1913 Added bend_start/bend_stop handlers for server. These handler are
1914 called on start/stop of server. For windows they are called whenever
1915 a service is started/stopped.
1917 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1918 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1919 in util/yc.tcl. The auto-generated C code structures are, in a few
1920 cases, incompatible with the old decoders. There are differences in the
1921 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1922 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1923 The preprocessor variable ASN_COMPILED is defined when the compiled
1924 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1925 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1926 wish to use the old encoders/decoders you can specify --disable-yc
1929 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1930 version so that it supports both new - and old version of DB Update
1932 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1933 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1934 change. The name parameter can be set to 0 in which no name is specified
1935 for the construction. The macros odr_implicit and odr_explicit sets name
1936 parameter to zero for the construction involved. New macros
1937 odr_implicit_tag and odr_explicit_tag are similar to the others,
1938 except that a name parameter is added. For programmers' that don't use
1939 ODR they probably only need to change the call to z_APDU and z_External.
1941 Added access control facility by interfacing the TCP wrapper library.
1942 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1943 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1944 name of the daemon and enables the access control as specified in
1945 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1947 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1948 den Dool <H.M.vdnDool@kub.nl>.
1950 Added reference ID parameter to most functions in server API - refer
1951 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1953 Changed name of ccl library to libccl.a (was ccl.a).
1955 Fixed bug in decoder for Explain (Category TargetInfo).
1957 Added support for GNU readline in client. Thanks to Jacob Poulsen
1958 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1960 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1961 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1962 IMPLEMENTATION! This change was made to the development version before
1963 the ZIG decided to retract the amendment. If any users MUST be
1964 compatible with the original Update definition, PLEASE CONTACT US, and
1965 we will include a separate definition corresponding to the old Update
1966 ES. Note that because of the change to the ASN.1 of the
1967 TaskPackageRecordStructure we cannot define a single structure that
1968 will support both versions.
1970 * Added const modifier to buffer parameter for some ODR/BER encoding
1971 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1972 completeWAIS, odr_dumpBER.
1974 Fixed bug in client.c which caused a crash when a scanResponse didn't
1975 contain positionOfTerm.
1977 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1978 * will cause an error in a client if a non-YAZ target sends both a
1979 * list of Scan entries and non-surrogate diagnostics.
1981 Retrieval module enhancements. Tag sets may be typed in the reference
1982 to it. From the .abs-file the "tagset" directive takes a third optional
1983 integer type for the tag set referenced. From a .tag-file the "include"
1984 directive takes a third optional type as well. The old "type" directive
1985 in the tag set itself is still recognized but acts as the default type
1988 Backend interface change. Individual Scan terms returned from bend_scan
1989 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1990 in include/backend.h.
1992 Retrieval module enhancements. Multiple tag sets and attribute sets may
1993 be specified in abstract syntax specs. Revised the error/warning for
1994 logging messages reported by the retrieval module when reading the
1997 Object Identifier system (oid_..) changed. The API is backwards
1998 compatible but the oid-routines now allocates new OID's when needed.
1999 Raw OID's may be specified in oid_getvalbyname.
2001 YAZ now uses GNU configure to generate Makefile(s).
2003 * Minor changes in some of the member names of DeleteResultSetRequest and
2004 DeleteResultSetResponse. See include/proto.h.
2006 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2007 and added member 'languages' in TargetInfo (which was missing).
2009 Changed the way attribute sets are handled in the retrieval
2010 module. These are now cached, just like the abstract syntaxes
2013 Changed YAZ so that it links with compiled ASN.1.
2015 Added Explain-schema definitions and mapping routines. The following
2016 Explain categories have been implemented: AttributeDetails,
2017 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2019 Fixed minor bug in Windows version of Server Library.
2021 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2023 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2025 Added EXTERNAL: UNIverse Resource Report (non-standard).
2027 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2028 ENUMERATED and SET OF.
2030 * Added 'const' to some of the char pointer arguments for the
2031 functions, data1_read_node, data1_getelementbytagname,
2032 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2035 Fixed bug in data1_insert_taggeddata - the last_child member of
2036 parent wasn't initialised.
2038 * Changed data1_read_record and data1_read_node so that the supplied
2039 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2040 doesn't refer to any parts of the "SGML"-buffer.
2042 Fixed bug in server library (Windows version of statserv_remove).
2044 * Changed code so that it compiles as C++. The type definition
2045 of Odr_fun which is a member of Odr_arm was changed. The result is,
2046 that an explicit typecast is needed for the fun pointer when
2047 using Odr_arm - as in:
2048 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2050 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2052 Implemented the new structured date and time definition as approved
2053 by the ZIG. Added schemaId element to the specificTag in Espec-1
2054 (also approved at the last ZIG). Thanks to RVDM.
2056 Added some Object identifiers (RVDM).
2058 Changed the Update Extended Service (RVDM).
2060 Added command "refid" to client which specifies referenceId for
2061 the following requests.
2063 Implemented extended service handling for server. See ztest.c
2064 for an example as well as backend.h. New handlers are registerd
2065 in the Init handler.
2067 * Changed interface for sort in server.
2069 Added new members to statserv_options_block. It allows a server
2070 to read options from another source than just the command line. Thanks
2071 to Charles Woodfield.
2073 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2074 renamed to zboolean. Some C++ compilers complained about the name.
2076 Minor changes to gils.abs. Added index 's' (sort) on title
2077 and date/time-last-modified.
2079 --- 1.4pl2 1998/1/30
2081 Fixed bug in server library regarding inetd mode (-i). This bug
2082 was introduced by release 1.4.
2084 --- 1.4pl1 1998/1/29
2086 Added sort facility in client and backend server interface.
2088 Fixed problem with dependencies in Makefile(s).
2090 Fixed bugs for encoders/decoders of extended services and
2093 Implemented sub-tree feature for schemas. Sub-trees are
2094 referenced in *.abs-files. See explain.abs for an example
2095 of the use of this feature.
2097 Modified bib1.att; local attributes for ANY didn't include
2098 ANY itself (only affects use of the retrieval module).
2100 Fixed bug in plain SGML reader in function data1_read_node:
2101 tags with prefix "var" was incorrectly interpreted as variants.
2103 Added feature "sub-schemas" to enable references to - and definitions
2104 of - group of elements.
2106 * Removed member parent from type data1_element (in data1.h).
2108 Implemented function odr_nullval() that returns the value of
2111 * Removed member num_children from data1_node (in data1.h).
2113 Made NT service interface part of the server library. The
2114 function statserv_main uses the NT service when required and
2115 calls the statserv_start / statserv_close routines.
2117 Routine zget_SearchRequest and zget_PresentRequest fills
2118 resultSetName/Id member with "default" instead of "Default".
2120 Fixed memory leak in server. Request queue member wasn't freed.
2122 Fixed nmem_exit so that memory is freed.
2126 Revised the CCL parser utility to be thread safe.
2128 Added function, oid_ent_to_oid, to replace the function
2129 oid_getoidbyent, which is not thread safe.
2131 * Added nmem_init and nmem_exit to initialize and release
2132 NMEM resources. Function nmem_init should be called once in the
2133 initial thread before NMEM/ODR is used. statserv.c and client.c
2134 have been changed accordingly. The change was necessary to make
2135 NMEM thread safe. The NMEM memory pool is shared amongst threads
2136 in a process. Unix-based applications will still work fine without
2139 Added NT Services interface for the the Z39.50 (statserv) Server.
2140 Refer to the ztest.c source on the usage.
2142 Windows 95/NT port using MSVC5.0. Project files are included in the
2145 * Defined new 'global' handle for the retrieval (data1) system. The
2146 new handled, data1_handle, describes the state of the data1 system.
2147 This handle is passed as first argument to virtually all
2148 data1 related routines. The functions data1_create and data1_destroy
2149 creates and destroys a data1 handle respectively.
2151 Added ODR encode stream member to all backend request structures
2152 init, search, scan etc. This stream should be used to allocate all
2153 memory used for the response when thread safe operation is needed.
2155 Changed the comstack utility, cs_addstr, to be thread safe. The
2156 returned hostname string returned by the function is now part the
2159 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2160 function. The cs_straddr takes a COMSTACK handle as argument, so this
2161 function must be used after cs_create and before bind/connect.
2162 This function is thread safe.
2164 Moved test server to 'ztest' directory - generic server code still
2165 in 'server' directory.
2167 Made prefix query (pquery.c) utility thread safe.
2169 Added new function modifier YAZ_EXPORT to 'export' public DLL
2170 functions when using windows (see include/yconfig.h).
2172 Added definitions to the OID database (util/oid.c) (RVDM).
2174 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2176 Added call to ccl_rpn_delete in client program.
2178 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2179 release of RPN structure.
2181 Added support for C++, headers uses extern "C" for public definitions.
2182 With input from RVDM.
2184 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2185 Thanks to Ronald van der Meer (RVDM).
2187 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2189 Added support for private extensions to the OID database
2190 (oid_setprivateoids()). Thanks to RVDM.
2192 Added optional, physical ANY (key replication)
2194 Fixed null-reference problem in GRS-1 output filter.
2196 Proximity operator added to Prefix Query Format (PQF).
2198 In test client command "base" accepts multiple databases.
2200 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2204 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2206 Smallish bug-fixes in the new encoders/decoders (explain).
2208 Bug fixed in DeleteRequest.
2210 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2212 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2214 Added SOIF syntax (using private OID for now) to retrieval module and client.
2216 Added Update extended service.
2218 Added SearchResult-1 additional info structure.
2220 Added optional CCL (ISO8777) interpreter as separate module. Available
2223 --- 1.2 1996/6/10 (1st anniversary release)
2225 Added Summary record syntax. Lightly tested.
2227 Added OPAC record syntax. Untested.
2229 Added ResourceReport service encoders/decoders. Untested.
2231 Fixed bug in z_Unit - wrong tagging on unitSystem.
2233 Fixed bug in the DiagRecs decoder.
2235 Added options for max PDU size and session timeout to frontend-server.
2237 Added documentation of query-language parsers and other supporting utilities.
2239 [frontend-server] Added Attribute set to the bend_scanrequest API.
2241 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2242 surrogate diagnostics were generated.
2244 [retrieval] Allow multiple local values for attribute.
2246 [retrieval] Allow multiple attributes per element in .abs files. index type.
2248 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2250 --- 1.1pl2 1996/4/10
2252 Minor changes, mostly specific to Zebra's requirements (retrieval)
2256 Repaired bug in frontend server when running multiple listening
2257 endpoints in dynamic mode.
2259 z_External() now won't break if a known, ASN.1 value comes encapsulated
2260 in an octet-string. The value will pass through unmodified in an Odr_oct.
2262 Added a bit of code to the demo client to decode & display
2263 ASN.1-structured records represented in the octet-aligned branch of
2264 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2266 Added z_ext_getentbyref() to the ASN module. Doc updated.
2268 * Completed the SCAN definition in the ASN module. This may break SCAN
2269 code based on older YAZ-versions at compile-time. The fix is easy -
2272 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2273 under the SCAN definition. Remember to initialize this, server-people.
2275 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2276 that this does not extend to ODR and ASN.
2278 Comstack allows insertion of established socket (primarily for
2279 inetd-operation of servers). Doc updated.
2281 Front-end server can now start from the inetd in TCP mode. Doc
2284 --- 1.0pl4 1996/1/24
2288 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2289 the rank and record number.
2291 Adjustments to the frontend server.
2293 Fixed diagnostic BER dumper. It ignored the file argument.
2297 Various changes to retrieval module.
2299 Changed the union discriminators of the protocol files from enums to
2300 ints paired with #defines.
2302 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2305 *Changed operator in the RPN structure to 'roperator', again to avoid a
2308 Fixed problems in Explain decoders/encoders.
2310 --- 1.0pl2 1995/12/6
2312 Memory bug in log module fixed.
2314 --- 1.0pl1 1995/12/5
2316 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2318 Bug in Explain DatabaseInfo module fixed.
2320 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2324 The shift to v1.0 signals that we now consider the *core* functionality
2325 of YAZ reasonably stable (the core being more or less equivalent to
2326 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2327 tested (Explain not at all - though that will happen soonish).
2329 Minor changes to code to support Windows port.
2331 Various minor changes after we're getting to use GRS-1 & co. more.
2333 Added Espec-1 format.
2335 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2336 of the protocol and it cannot be selected when encoding (maps into 'string'
2337 when decoding). Needed to talk to some servers.
2339 Demo client can request simple element set names.
2341 Added Diagnostic Format encoders/decoders.
2343 Added simple Close handling to frontend server (no hooks for resource
2344 reporting yet), and demonstration client.
2346 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2348 --- 1.0b3 1995/08/24
2350 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2351 handled incorrectly when records were requested in the searchResponse. This
2352 will only affect you if you use the frontend-server.
2354 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2355 Test-client will ask for and print GRS1. Ztest will return dummy records
2358 Added Explain encoders/decoders to the service-level API. Untested.
2360 Added Extended Services: Item Order encoders and decoders to the Service-
2361 level API. Untested. We could use a recent copy of the pertinent bits
2362 of the ILL protocol to add those bits.
2364 Added diagnostic format 1 encoders/decoders to the service-level API.
2367 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2368 odr_cons.c, which causes a more correct output.
2370 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2371 was always set to 0 when no records were requested in the searchRequest.
2373 * Added better external-handling. This shouldn't harm old code that
2374 *encodes* externals. It can break code that looks for a
2375 'single-ASN1-type' representation, since those types that are known
2376 are now decoded immediately. Look at the SUTRS sample code in
2377 seshigh.c and client.c. Documentation updated.
2379 Handling of structured records in bend_fetchresponse. Length -1 marks
2380 structured record, type is deduced from format field.
2382 --- 1.0b2 1995/06/27
2383 Fairly quick maintenance release to add SUTRS support.
2385 Fixed handling of SUTRS records in the demonstration client.
2387 * Added format field to the bend_fetchrequest and bend_fetchresponce
2388 structures of the backend API (frontend server). When the record is
2389 returned, the value of the format field is mapped to an OID. The
2390 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2391 of the record. The special value VAL_NONE in the bend_request means
2392 that no specific format was requested by the client. Documentation
2393 updated accordingly. Test server (ztest) will return a fixed dummy
2394 SUTRS record if your client requests SUTRS.
2396 Documentation updated accordingly.
2398 You can now set external libraries and RANLIB support in the top-level
2402 First public release.
