1 Improved speed of MARC-8 encoding.
3 Added support for lossy and loss-less MARC-8 encoding.
5 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
7 Added new Windows Service wrapper (sc).
9 yaz-client's itemorder command may now send a file.
11 Fixed yaz-marcdump to allow the use of NS prefix for record element.
13 Added new function yaz_log_xml_errors.
15 Allow (but warn) unknown XML attributes in MARCXML parsing.
17 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
19 The UTF-8 to MARC-8 conversion now uses a different set of characters
20 for Greek symbols. Bug #2120.
24 Added yaz_daemon (daemon.h).
26 Fixed bug #2068: pkg-config trouble
28 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
32 Document --with-xml2 option.
34 Added OPAC XML XSD (etc/opacxml.xsd).
36 Allow glob mask for name attribute in retrieval element for the
37 generic frontend server's retrieval facility.
39 Changed yaz_poll_poll to return yaz_poll_except for all returned events
40 except POLLIN/POLLOUT.
42 Fixed error handling in cs_listen. Bug #2037.
46 Fixed version in yaz/yaz-version.h.
48 Fixed bug #2027: Crash when closing connection.
50 Changed configure so that ICU support is only enabled if only ICU
51 and Libxml2 is available (because the ICU chain is XML based).
55 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
56 is built. Only this DLL depends on the ICU runtime.
58 yaz-ziffy is no longer part of YAZ. It is distributed separately by
59 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
61 Changed license of CCL module to 'Revised BSD'. After consultation with
62 remaining members of the original EUROPAGATE consortium, we are re-issuing
63 the CCL module without a separate license. The software was developed by
64 Index Data as part of a research project. The special license was included
65 to help feed usage information back to the project consortium to support
66 project evaluation. At this time, the project consortium has long-since
67 disbanded, and the majority of the original principals have retired. At the
68 same time, we have significantly modified the software during the following
69 years, to the point where very practically no original code remains. To
70 simplify re-use of the software, we have contacted those members of the
71 consortium who could be reached, and agreed to re-issue the module as a
72 proper part of the YAZ package.
74 Tcl scripts uses /usr/bin/tclsh as preferred shell.
76 CQL closer to being version 1.2 compliant. CQL also allows free-form
77 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
80 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
81 bug could make Extended services handling crash in the ZOOM layer. This
82 bug was only present in YAZ 3.0.18.
86 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
89 yaz-marcdump reads and writes collection wrapped records.
91 Handle OPAC for record conversion module.
93 Fixes for ICU wrapper.
95 Allow ICU libs to be controlled with --with-icu .
99 Added yaz_poll which is a wrapper for select/poll. When poll is available
100 and non-buggy, it is used, by yaz_poll . This allows more than 1024
101 sockets to be in use.
103 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
104 functionality through an XML based configuration (ICU chain). This system
105 is useful for search facilities such as Pazpar2 and Zebra that needs to
106 perform tokenization of indexed material. The ICU code in a separate
107 library libyaz3_icu.a.
109 Added HTTP tunnel facility for COMSTACK, bug #1752.
110 This is a facility that allows a Web proxy, such as squid, to tunnel
111 Z39.50 traffic. This facility is "transparent" to must applications
112 using YAZ. It's enabled by using pseudo transport connect: followed by
113 the proxy address, followed by command, then follwed by he regular
114 "virtual" addresss. For example,
115 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
117 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
119 --- 3.0.14 2007/09/21
121 Fixed bad memory reference in ZOOM_record - cuased by member not being
122 initialized. This was a problem only in YAZ 3.0.12.
124 Fixed bug in conversion from MARC to XML: Non-XML characters in control
125 fields were not removed.
127 Changed the way C code is generated from codetables.xml. Made a MARC-8
128 conversion trie for each characterSet section rather than codeTable.
129 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
130 of codetables.xml from Larry Dixson, LOC. Bug #1464.
132 --- 3.0.12 2007/09/12
134 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
135 from ZOOM_record_error).
137 ZOOM C function ZOOM_record_get returns record schema for type="schema".
139 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
141 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
143 Better SRW-to-Bib-1 diagnostic mapping.
145 ZOOM C and yaz-client announces SRU version 1.2 by default.
147 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
150 Fixed in yaz_sru_decode to allow other version than 1.1.
152 --- 3.0.10 2007/08/22
154 Added support for SRU scan for ZOOM.
156 Added support for the use of the older versions or Extended Service
157 Update in ZOOM. To faciliate this, an option "updateVersion" may be
158 set to the version , 1=first, 2=second, 3=third. The third version is
159 what ZOOM C has used so far. And that, obviously, is the default.
161 Added support for CCL queries in Z39.50 queries sent to the GFS (and
162 therefore in Zebra and in SimpleServer-based applications). The new
163 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
164 qualifier file used to transform incoming CCL queries into Type-1 RPN,
165 which is passed into the back-end search callback function.
167 Added support for HTTP Basic authentication in clients: the SRU/W
168 codec encodes the username/password elements of the PDU structure
169 appropriately, and these may be set using the "user" and "password"
170 options in ZOOM-C applications (the same options that are used for
171 Z39.50 authentication).
175 Fixed bug #1208: SSL appears to be broken in ZOOM.
177 Fixed bug #1206: Libxml2 include path weirdness.
179 Added oid_name_to_dotstring.
181 Allow elementSetName to be specified for ZOOM C record update.
183 Allow waitAction to be specified for ZOOM C based for Extended Services.
185 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
186 syntax OID. Bug introduced in YAZ 3 series.
188 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
192 Fixed bug #1157: yaz-client does not read .yazclientrc from current
193 directory. yaz-client now reads commands from file given by option -f
194 if specified; then tries to read .yazclientrc in current directory.
195 Failing that, it reads .yazclientrc from user's home directory.
197 Added support for correlationInfo Note and ID for Record Update via
200 Added yaz-client command querycharset which specifies character set for
201 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
202 (termListAndStartPoint).
204 Charset ISO5428:1984 is an alias for ISO5428-1984.
206 Implemented a way to perform scan in a result set using Z39.50. This
207 is achieved by attaching the result set name in the characterInfo
208 (type InternationalString) of OtherInformation in the Scan Request PDU.
209 The result set is identified in the otherinformation by the new OID:
210 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
211 This allows for scan in result set and faceted search . Zebra did some
212 of this in the APT term using attribute type 8 and value being result
213 set. Using the OtherInformation approach for this is cleaner and easier
214 to work with in proxies and the like. This facility can be used in
215 yaz-client using new command setscan which takes a result set as first
216 argument, start position (APT) as second.
218 Changed decoding of SRU XML packed records to deal with servers that
219 have recordData with XML data with multiple root nodes. Also make
220 comparison for recordPacking case insensitive. Again, one server
221 returns "XML" where others return "xml".
223 For SRU responses allow Content-Type application/xml as well as text/xml.
227 Fixed bug in character set conversion of BER strings. Bug introduced
232 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
234 For OID class, use oid_class consistently.
236 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
239 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
240 character set for bibliographic information interchange". By Giannis Kosmas.
242 Added documentation on new OID API.
246 Changes to generic frontend server interface: added new member
247 'query_charset' for bend_initrequest structure. A backend init handler
248 should set this member to its native character set for query terms.
249 When defined, the frontend server logic will announce this character set
250 to a client if the negotiationModel bit is set by the client. All server
251 implementors are encouraged to specify this. If a backend server does not
252 specify this a warning is issued using yaz_log(YLOG_WARN,..).
254 Added CCL utility to remove terms (stop words) from resulting RPN
255 tree. This is handled by functions with prefix ccl_stop_words_ .
257 New ZOOM C option, "rpnCharset", which allows client-side conversion of
258 terms in RPN queries.
260 Clean-up the CCL API. Moved some internal structures from ccl.h to
261 private header cclp.h. Changed ccl_parser_create so that a Bibset must
262 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
263 This is replaced by ccl_parser_find_str which takes a string instead.
265 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
266 libyaz.la is the core of YAZ except the generic frontend server and
267 does not depend on POSIX threads anymore. libyaz_server.la is the
268 generic frontend server facilities and uses POSIX thread functionality
269 if available. The libyaz.la no longer depends on POSIX threads because
270 the number of global structures is limited. NMEM no longer re-uses blocks
271 between threads ; it simply free's memory immediately but allocates in
272 "large" chunks as usual. We don't expect any performance penalties
273 because of this. The yaz_log system is still using a global log_level so
274 caution must be taken when modifying it with yaz_log_init_.. +
275 yaz_log_mask_str. This, however, should not cause any trouble because
276 these functions are called during initialization of application code
277 anyway. `yaz-config --libs server` returns libs for server applications;
278 `yaz-config --libs` returns libs for non-server applications.
280 New OID database - with public definitions in oid_db.h. Removed old OID
281 database including the head oid.h and definitions such as enum oid_value
282 and struct oident. The new OID database uses the same string names as
283 before but the 'protocol' is gone. There are now only two representations
284 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
285 converts from string to OID; functions with prefix yaz_oid_to_string
286 converts the other way.
288 Change to emit_term() in CQL-to-PQF query translation: when a term has
289 the /regexp relation modifier, do not process it for leading and
290 trailing "^" and "*", which have quite different meanings in regular
293 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
294 write handlers no longer carries a 'last' parameter. This will make
295 yaz_iconv flush "less" characters. A flush is performed by call to
296 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
298 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
299 removed, because function yaz_query_to_wrbuf does the same.
301 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
302 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
304 Deprecated MARC utility functions removed.
306 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
309 Branch split: YAZ_2_1_55_branch
311 --- 2.1.54 2007/03/16
313 Fix to ZOOM-C so that transparent reconnection is properly handled on
314 connections that are in asynchronous mode.
316 Fixed compilation on OpenBSD 4.0.
318 Large strings in GRS-1 records are now properly displayed in yaz-client.
320 Added character conversion support for "advancegreek"; based on patch from
323 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
324 sequence is met. Before the error was not set so it would be unknown.
326 Adjust yaz-marcdump MARC reader so that it skips until record separator
329 --- 2.1.52 2007/03/07
331 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
332 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
333 fd_set structure used as a bitmask for the FDs to be selected on.
335 Using ACX_PTHREAD macro to check for POSIX threads.
337 Fixed have-vsnprintf check.
339 --- 2.1.50 2007/02/23
341 Fixes for configure on BSD. Bug #900.
343 Added snprintf/vsnprintf wrappers for systems that don't have
344 limits (heavens forbid).
346 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
347 created before all previous tasks were completed and removed from the
348 task queue, the new task could be removed by a mistake.
350 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
352 Implemented pass-through CQL-to-PQF conversions. Bug #861.
354 Fixed bug #832: Problem with MARC/charset in yaz-client.
356 Fixed bug #668: save command line history for yaz-client.
358 Fixed bug #830: pkg-config support.
360 --- 2.1.48 2007/01/23
362 Extended ZOOM result set options with two options that may be read by
363 a client: resultSetStatus and presentStatus with values as specified for
365 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
367 Fixed bug #827: Using SSL fails on Debian etch.
369 Fixed bug #826: Weird looking chars for set of MARC records.
371 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
372 that is treated as an ItemOrder with itemRequest being an XML document
373 external. The value of "doc" is the content.
375 Extended the GFS search facility. New member of bend_search_rr
376 'estimated_hit_count' signals that hits is known to be an estmate
377 (higher or lower than real hit count). New member 'partial_resultset'
378 signals that the search was partial (hit count is lower or equal than
379 real hit count). For Z39.50, the information is stored in resultSetStatus
380 member of SearchResponse APDU. For SRU, the information is signalled
381 via SRU diagnostic 59: "Result set created with valid partial results
384 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
386 --- 2.1.46 2007/01/13
388 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
390 Added ZOOM_connection_peek_event.
392 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
393 the following new functions:
394 ZOOM_event_nonblock, ZOOM_connection_process,
395 ZOOM_connection_get_{socket,mask,timeout},
396 ZOOM_connection_fire_event_{timeout,socket}.
397 The existing blocking event handler, ZOOM_event, is a wrapper for the
398 + blocking ZOOM_event_sys_{poll,select}.
400 Implemented function ccl_xml_config which parses XML version of CCL
401 configuration (bug #798).
403 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
405 Added timings utility (yaz/timing.h)
407 --- 2.1.44 2007/01/03
409 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
412 Fixed bug #779: Rotation of apdu.log fails.
414 Fixed for character set conversions:
415 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
416 Honor G1 set in MARC-8 decoding.
418 --- 2.1.42 2006/12/17
420 Fixed bug #775: char conversion does not handle Alternative UTF-8
423 Implemented function yaz_marc_read_line which parses MARC line format
424 records. There is a wealth of formats out there. So far, this function
425 reads line records produced by yaz_marc_write_line.
427 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
428 more generic and easier to remember(!) options: -i format and -o format
429 which specifies input format and output format respectively - where
430 format is one of "marc", "marcxml", "line", "marcxchange".
432 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
433 does not print anything except warnings for records.
435 For yaz-marcdump, added support for MARC split into files (-s) with a given
438 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
439 spec, at http://www.loc.gov/standards/sru/record-update/
440 This has changed the binary layout of the following structs:
441 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
442 bend_update_rr . Patch by Ko van der Sloot.
444 Added GFS utility function bend_assoc_is_alive which returns 1 if
445 association is still alive (client is connected); 0 otherwise (client
446 closed connection). This allows busy servers to stop working for
449 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
450 been a separate piece of software. This version of ziffy has been modified
451 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
453 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
455 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
456 Client code may now interrogate options such as "init_opt_sort" to
457 find out whether the server claims to support various options.
459 --- 2.1.40 2006/11/27
461 Added utilities yaz_{set,get}_esn to set/get element set name from
464 Removed the build of libyazthread.la. The libyaz.so is the threaded version
465 of YAZ and has been so since YAZ 2.1.10.
467 Implemented ZOOM_record_error which returns error information for
468 record (surrogate diagnostic).
470 --- 2.1.38 2006/10/31
472 Updates for SRU Update by Ko van der Sloot:
473 1. Changed name from "operation" to "action"
474 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
475 versions in the code, marked as 'backward compatible'.
476 3. Added diagnostics for SRU Update.
478 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
480 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
482 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
484 For GFS, fixed problem with SRU diagnostic 'First record position out of
485 range' being issued for 0 hits.
487 zoomtst10 part of Windows Build.
489 --- 2.1.36 2006/10/13
491 Implemented yaz_filepath_comp which splits a path into file path
492 components (required by Zebra 2.0.3+).
494 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
495 BSD inspired license until now so this should not have any real impact on
496 anybody. See http://www.opensource.org/licenses/bsd-license.php
498 Fixed bug #687: Missing log lines.
500 Fixed bug #678: CQL to PQF translation does not preserve double-quote
503 Fixed bug #689: SRU diagnostics to be added.
505 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
506 whether a connection is idle (no more work do do).
508 --- 2.1.34 2006/10/04
510 Change type of optval from long to int for invocation of setsockopt with
511 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
513 Added support for specifying the max log file size for the Generic
514 Frontend Server. The size is given with option -r.
516 --- 2.1.32 2006/09/21
518 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
520 --- 2.1.30 2006/09/17
522 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
525 Fixed bug in Generic Frontend Server that could cause a server to stop
526 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
528 For the generic frontend server, the maximum record size is used as maximum
529 size of incoming packages (SRU + Z39.50). The value until was previously
530 only used in Z39.50 Init negotiation and, later, in a session controlled
531 sizes of records returned. This is controlled using -k option. It can be
532 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
534 --- 2.1.28 2006/09/04
536 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
539 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
541 New option for yaz-marcdump -lpos=value which allows setting a portion
542 of MARC header to a certain value.
544 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
546 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
547 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
549 --- 2.1.26 2006/08/15
551 Fixed problem with SRU mode type (soap, get, post) for yaz-client
554 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
556 --- 2.1.24 2006/08/08
558 Fixed MARC ISO2709 encoding routines to deal with character set
561 Minor changes to GFS logging. Database included in search request log
564 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
565 cached/multiple records.
567 Shared libraries are built by default on Unix+configure.
569 Changed cql2pqf transformation to use a different evaluation order. The
570 new order is: always, relation, structure, position, truncation, index
571 and relationModifier. Old order was: always, relation, relationModifier,
572 structure, index, position, truncation. Note that the the latter ones
573 override former ones for identical attributes.. The new scheme means that
574 it is possible to override any existing attribute with a relationModifier.
575 And also that it is possible to override everything for the index rule
576 (except the ones listed in relationModifier). No order is perfect but this
577 one, we believe, covers more real cases.. The "always" should have been
578 called "default", since the attributes there can be overridden with all
581 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
582 compilation phase, but also for yaz-config --cflags output. This allows
583 us to have public headers with Libxml2 stuff in them . It should also,
584 eventually, make Libxml2 checks redundant in packages using YAZ, such
587 --- 2.1.22 2006/06/15
589 Changed SRU update structure bend_update_rr so that SRU diagnostics are
590 stored in uri, message and details.. Previously diagnostics were stored
591 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
592 compatibility.. but he's probably the only one affected, so.
594 Added support for CCL, compiled on the client side, in ZOOM-C. This
595 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
596 input; the resulting query objects can be used for for searching with
597 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
599 YAZ' configure searches for OpenSSL by default.
601 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
602 SL_CTX_use_certificate_file. See
603 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
604 for more info. Thanks to Ko van der Sloot.
606 --- 2.1.20 2006/06/02
608 Bug #600: SRU GET, POST support for yaz-client. Introduced
609 command 'sru' which selects method SOAP/GET/POST.
611 Allow missingValueAction to be specified for the sortspec string -
612 function yaz_sort_spec. By default, the missing value action is null.
613 Use ! to specify "abort". Use = followed by stringvalue to specify default
616 Ensured that Present-handler (if defined) is called in GFS before any call to
617 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
618 searchRetrieve requests.
620 Documentation for YAZ is now based on the Docbook XML/XSLT using
621 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
622 is no longer depending on jade/openjade or docbook-to-man scripts.
623 PDF is no longer part of the distribution - but can optionally be
624 made using DSSSL/jadetex or FOP.
626 Added retrieval handling support in Generic Frontend Server to support
627 conversion between MARC/XML as well as XSLTtransforms. See
628 etc/yazgfs.xml for an example.
630 Added Authentication support to Generic Frontend Server in SRU
631 mode. Authentication using HTTP Basic is supported, as is the use
632 of 'x-username' and 'x-password' parameters in the request itself.
634 Added support for a new character set MARC8s identical to MARC8 except
635 that it converts combined characters to single Unicode characters in the
636 Latin-1 range (when possible).
638 --- 2.1.18 2006/04/24
640 ASN.1 compiler 0.4: generates brief Doxygen file header for
641 generated .h/.c files.
643 Utility yaz_iconv now supports conversion to MARC-8.
645 New facilities for the MARC module. The reading - and writing of
646 content are separate methods for the yaz_marc_t handle. The following
647 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
648 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
649 format). Write functions have prefix yaz_marc_write_.. The existing
650 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
651 available. Removed support for OAI-MARC and simplexml (not the
652 simplexml from PHP5).
654 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
655 to be returned for this connection.
657 --- 2.1.16 2006/03/31
659 Allow multiple languages and charsets to be specified with
660 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
661 negcharset iso-8859-1,utf-8
663 Translation of proximity nodes from CQL into PQF now works.
665 Moved to automake 1.8, 1.9.
667 Added function yaz_log_set_handler which allows a log handler to be
668 installed. This handler will be called for all log messages. Output
669 to file is also produced; but that can be disabled by passing NULL
670 fname to yaz_log_init_file.
672 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
674 For SRW (including GFS), accept application/soap+xml as content-type
677 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
678 produces NO stylesheet reference even if a default stylesheet is specified
681 --- 2.1.14 2006/03/14
683 Updated Windows package to include yazd.dll + yazd.lib for the
684 Development component.
686 If the environment variable YAZ_LOG is set, then it is used as a
687 string indicating the default level of logging to use if not
688 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
689 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
690 used as before. So, for example, to omit warnings from YAZ logging,
693 cql_transform() now map structure and other attributes before indexes,
694 so that index-specific structures and other attributes can override
695 defaults. So now a combination of mapping specifications such as:
697 index.dc.date = 1=date-modified 4=5
698 does the right thing.
700 cql_transform() now also respects the "always" mapping specification,
701 which establishes an initial set of attributes to be used for all
702 terms except where overridden by more specific attributes associated
703 with the index, relation or modifier.
705 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
706 which mode to use; one of "post", "get" or "soap" (SRW, default).
708 Fixes for yaz_iconv routines: changed trie-based character set conversions
709 to use only non-negative values for bit fields due to Sun's C compiler not
710 supporting negative values.
712 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
713 sequences where not read correctly. Fix by Rustam Usmanov.
715 Updated win/makefile to use options, settings which makes things
716 compile with VS C 2005.
718 --- 2.1.12 2006/02/01
720 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
722 In ZOOM socket code, use select instead of poll on MacOSX.
724 ZOOM-C now support client-side compilation of CQL into RPN that is
725 sent to the server, enabling CQL to be used against all Z39.50
726 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
727 ZOOM_query object, and submit it using ZOOM_connection_search().
728 The CQL-to-RPN translation uses a configuration file, the name of
729 which must be specified in the Connection's "cqlfile" option.
731 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
732 function, which takes as its start-term parameter a ZOOM_query object
733 (which may have had either CQL or RPN set into it).
736 --- 2.1.10 2005/11/29
738 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
739 GFS to support this as well. Backend handler, bend_srw_update, does the
740 update work. Code contributed by Ko van der Sloot.
742 Allow retrieval of Search Result-1 information in ZOOM by the use of
743 options that are attached to a result set. ZOOM documentation updated
746 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
747 UTF-8 conversion. Patch by Raj Patel.
749 Added option -m to GFS to control formatting of timestamps in log file.
751 Added 'exit' as synonym for 'quit' in yaz-client
753 Added support for specifying SRW resultSetId + resultSetIdleTime in a
754 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
755 for the new members. Patch by Ko van der Sloot.
757 Added support for SRU POST. It is supported for content-type
758 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
760 Do not build the separate Multi-threaded (MT) library libyazthread.la.
761 Instead make the library libyaz.la multi-threaded. Threading as a whole
762 can still be disabled by configure option --disable-threads. Previosly,
763 with older GLIBCs there were problems with MT libs under Apache. This
764 has now been fixed a long time ago.
766 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
769 CQL module modified to be case insensitive for relations/indexes/operations.
771 Fixed bug in CQL transform code: incorrect value relationModifieder
774 Added 'show all' command for yaz-client which retrieves all results
777 Added new yaz-client, xmles, which takes a (private) OID and
778 a document to be sent as an extended service request.
780 Describe new yaz-client commands wait_response and set_auto_wait.
782 Increase TCP/IP listener backlog from 3 (which I am guessing was
783 copied from the SunOS manual entry way back when) so SOMAXCONN, so
784 that the socket will queue as many incoming connections as it's able
785 to handle ongoing connections. In other words, it will never now
786 refuse a connection that it would be able to handle merely because
787 it's not got around to accepting() enough of the pending connections
788 yet. This is the behaviour anyway under Linux, where the listen()
789 argument is ignored; but not under BSD and on systems such as
790 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
791 YAZ-based servers should now be uniform across operating systems in
794 yaz-marcdump uses 64-bit file access on some systems. This is enabled
795 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
796 This allows yaz-marcdump to read large MARC batches (>2 GB).
798 Modified all YAZ source files - except the source which is auto-generated
799 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
802 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
803 corresponding to the existing *_setl() function. These allow option
804 values containing arbitrary valuues.
806 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
807 ZOOM_resultset_sort() in new applications. Its behaviour is identical
808 except that it returns an indicator of whether or not the sort
809 criterion was accepted (0 for OK, -1 for invalid).
813 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
814 MARC output rather than returning "new" buffer.
816 yaz-client warns about unknown init options.
818 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
822 Added support for SRW sort in Generic Frontend Server. Patch
823 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
824 sortKeys - or NULL if none is provided.
826 Fixed bug #307: It was impossible to specify indefinite/no timeout
827 for ZOOM_event. Special timeout value -1 now means indefinite timeout
830 Added support for multiple languages and charsets to be specified in
831 ZOOM. Each charset/language is separated by a blank. If negotiation is
832 in effect in init-response, Option
833 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
834 Code based on patch by Vasiliy Osadchuk.
836 Fixed bug #306: infinite recursion that occurred when calling
837 yaz_log_level_init as the first call (before other log level or
840 Fixed bug in scan handling in front end server: if preferred-Position-In-
841 Response was non-present, a NULL pointer referece was performed.
845 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
846 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
847 now defined for all those error codes. So instead of putting 109 in
848 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
849 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
851 Modified the yaz-marcdump utility to skip garbage bytes between MARC
854 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
856 Program yaz-client now exits and produces an error message if multiple
857 Z39.50 servers are specified on the command line (none or one allowed
860 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
865 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
867 Fixed bug #272: Preserve spacing for CCL terms.
871 Added support for virtual hosts and multiple backend servers for
872 the YAZ frontend server. The configution is XML based and
873 support specificition of CQL to RPN mappings and explain information.
874 See section "Virtual Hosts" in the YAZ manual.
876 Extended OPAC display utility. OPAC display utility renders
877 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
878 to supplement yaz_marc_decode_wrbuf.
880 Fixed a bug in MARC decoder that could caused it to crash for some
881 invalid MARC records. More diagnostics and warnings where added in
882 XML output (warnings, etc are stored in comments).
884 --- 2.0.34 2005/02/08
886 Fixes for UNIX domain sockets. Bug #261.
888 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
890 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
891 Added yaz_marc_subfield_str which defines subfield lead string which is
892 used in YAZ_MARC_LINE format. Default string is blank+$. Added
893 yaz_marc_endline_str which defines end of fields string used in
894 YAZ_MARC_LINE format. Default string is newline.
896 Experimental support for MarcXChange. This format can be produced
897 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
898 http://www.bs.dk/standards/MarcXchange.xsd
900 Added yaz-client commands scansize that sets maximum number of
901 entries to be returned by scan.
903 --- 2.0.32 2005/01/11
905 Added support for SRW scan in yaz-client and Generic Frontend Server.
907 * Added whereInList member to SRW Scan Term.
909 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
911 Fixed NMEM system to return aligned blocks on the smallest boundaries
912 that are suitably aligned for all possible types on the particular
913 architecture YAZ is being built for.
915 --- 2.0.30 2005/01/04
917 Fixed numerious warnings that was issued with newer versions of GCC.
919 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
920 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
923 Make YAZ Generic Frontend Server slightly faster.
925 Enhance (and reduce) logging for Generic Frontend Server.
927 Revert YAZ log system so that it flushes every write operation
928 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
930 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
931 instead of LOG_, due to name clash with syslog(3). LOG_ are still
932 present. New applications should define YAZ_USE_NEW_LOG=1 - this
933 will effectively disable old definitions.
935 --- 2.0.28 2004/11/09
937 Added yaz_log_time_format which specifies log format using
940 Added yaz_log_module_level which returns mask for a module. Value
941 is non-zero mask a if module is enabled; zero if disabled.
943 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
944 in include/yaz/cql.h.
946 Fixed bug #176: Dont throw diagnostics on empty SRU args.
948 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
950 Fixed bug #172: RPM builds does not enable SSL.
952 Doxyfile.in part of dist. Doxyfile generated by configure.
954 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
955 are given and the corresponding component does not exist.
957 Extend CCL documentation in YAZ reference. Describe r=r.
959 --- 2.0.26 2004/10/01
961 Fixed MARC->MARCXML conversion to properly deal with
962 fields, subfields, indicators having non-ASCII characters.
964 Fixed MARC->MARCXML conversion so that ASCII control characters
965 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
968 Added YAZ GFS support for conversion from Z39.50 surrogate
969 diagnostics to SRW surrogate diagnostics.
971 Bug fix: YAZ GFS did not return schema in explainResponse.
973 --- 2.0.25 2004/09/30
975 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
976 now converts recordSchema to elementSetName as well as schema URI.
978 Fixed bug in COMSTACK that prevented HTTP request packages from being
981 --- 2.0.24 2004/09/29
983 Added CCL facility r=r "range" which is similar to r=o "ordered" but
984 does not require white-space before and after the dash in a range, e.g.
985 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
988 Fixed a few AC_TRY_LINK configure tests that did not operate properly
989 due to new GCC removing "redundant" code.
991 Added yaz-client commands scanpos and scanstep that sets preferred
992 position and step-size for scan.
994 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
996 Added CCL utility ccl_qual_buf which parses one or more CCL
997 spec lines in a buffer.
999 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1000 of name and value - ignoring empty lines and comments.
1002 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1004 Added odr_get_element_path which returns current element path for an
1005 ODR handle. This utility is useful in error handling or user-defined
1008 Added ODR_PRINT utility odr_set_stream which is is a more generic
1009 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1010 to a write function and pointer to close function. The close function - if
1011 non-NULL - will be called during odr_destroy.
1013 Fixed bug in CCL parser where truncation char was not removed from
1014 right side when truncation=both was in effect.
1016 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1019 --- 2.0.23 2004/08/11
1021 Fix buffer overrun in CQL parser when dealing with proximity (%).
1023 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1024 to UTF-8/UCS conversion is now only based on codetables.xml.
1026 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1028 --- 2.0.22 2004/08/06
1030 Add support for more "commit changes" in ZOOM (uses Extended Services).
1032 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1035 Yet another small fix for configure of SSL.
1037 --- 2.0.21 2004/05/14
1039 Fix SSL libs for configure when --with-openssl=DIR is given.
1041 --- 2.0.20 2004/05/10
1043 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1045 SSL comstack now uses yaz.pem certificate file on server side
1046 by default. Certificate filename can be configured by calling
1047 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1049 Fix bug regarding multiple calls to ZOOM_connection_connect.
1051 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1053 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1054 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1056 ZOOM now allows inspection of X509 peer certificate for verification.
1057 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1059 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1060 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1061 as "modular" but it simplifies things.
1063 Added cs_get_peer_certificate to that returns peer X509 PEM.
1065 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1066 NULL if SSL is unavailable.
1068 Documentation about MARC decoding tools.
1070 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1072 --- 2.0.19 2004/03/30
1074 Rename CHANGELOG to NEWS to follow GNU style packing.
1076 Fix bug with missing initialization of member in init_diagnostics.
1077 This bug affects threaded version of GFS server.
1079 --- 2.0.18 2004/03/20
1081 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1084 Ensure zlib.dll is packed with Windows install.
1086 --- 2.0.17 2004/03/17
1088 Fix encoding of xsd:string to use text instead of CDATA.
1090 Fix endless loop in CQL parser with unbalanced ".
1092 Use a more compact way to store MARC-8 conversion tables.
1094 --- 2.0.16 2004/03/16 Debian only
1096 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1099 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1104 --- 2.0.15 2004/03/01
1106 Another fix for decoding of XML packed records.
1108 --- 2.0.14 2004/02/25
1110 Fixes for Chunked encoding. White space not ignored after length spec.
1112 Update NS and use default NS for SRW diagnostic elements.
1114 --- 2.0.13 2004/02/23
1116 Implement ZOOM_resultset_cache_reset which resets record cache.
1118 Implement ZOOM_resultset_sort which sorts a result set.
1120 Implement chunked HTTP transfer.
1122 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1124 --- 2.0.12 2004/02/16
1126 Added member 'schema' to bend_explain_rr structure so that backend
1127 can specify explain record identifier. Defaults to Zeerex 2.0.
1129 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1131 --- 2.0.11 2004/02/16
1133 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1136 Added init command for yaz-client which sends "extra" init request.
1138 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1139 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1141 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1143 Make ZOOM error code for "invalid query".
1145 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1147 --- 2.0.10 2004/02/05
1149 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1152 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1154 Added option -p <file> to make Generic Frontend Server to write PID file.
1156 Added option -D to put Generic Frontend Server in background on its own.
1158 Make ZOOM C recognize option "password". If unset, "pass" is used
1159 (for backwards compatibility).
1161 Fixed a bug in Generic Frontend Server that could make it crash if a
1162 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1165 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1166 Must be issued before open, in order to be in effect.
1168 --- 2.0.9-6 2004/01/12 Debian/Windows
1170 Make the SRU server more picky WRT unknown params, etc.
1172 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1174 New YAZ client command, options, that sets Z39.50 options.
1176 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1177 options from a string of tokens (one token for each option bit).
1179 Update SRW diagnostic code messages.
1181 --- 2.0.9-5 2004/01/07 Debian/Windows
1183 Handle user defined stylesheet for SRW/SRU.
1185 --- 2.0.9-4 2004/01/06 Debian/Windows
1187 Fix bug in decoding of Content-Length.
1189 --- 2.0.9-3 2004/01/06 Debian/Windows
1191 Fix a bug with decoding of XML packed records.
1193 --- 2.0.9-2 2004/01/05 Debian only
1195 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1197 Fix bug in SRW/SRU diagnostics decoding.
1199 --- 2.0.9 2004/01/05
1201 Fixed bug in Generic Frontend Server which could drop records exceeding
1202 preferred message size. Reported and fixed by Irina Dijour.
1204 Fixed calculation of package size for structured records in Generic
1205 Frontend Server. Reported and fixed by Irina Dijour.
1207 Fixed namespace for SRW/SRU diagnostics.
1209 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1211 --- 2.0.8 2003/12/22
1213 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1214 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1217 CQL changes to reflect recent changes to the specification:
1218 * Documentation talks about context sets instead of index sets.
1219 * Documentation talks about indexes instead of qualifiers.
1220 * The CQL-to-PQF transformer's configuration file now uses
1221 "index.set.name = <attributes>" instead of the old form
1222 "qualifier.set.name = <attributes>". (Both forms are still
1223 understood but the latter is deprecated.)
1224 * CQL terms with no explicit index specified are now interpreted as
1225 cql.serverChoice instead of srw.serverChoice (which of course
1226 behaves exactly the same.)
1228 --- 2.0.7 2003/12/16
1230 MARC conversion can now generate ISO2709 output in another
1231 character set. yaz-marcdump uses this facility if you invoke it
1234 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1235 functions from there can be used from C++.
1237 --- 2.0.6 2003/12/04
1239 Frontend server now transfers memory from decoded packages to stream
1242 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1243 references to show up.
1245 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1246 the ZOOM Abstract API. The older names for the same options are still
1247 also supported for the benefit of old applications.
1249 ZOOM-C supports "implementationId" and "implementationVersion" options
1250 to go along with "implementationName". These allow the user code to
1251 specify identification strings to be sent to servers.
1252 Add OID for the new ExtLite attribute set.
1254 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1255 as requested/supplid by Ere Maijala <ere@atp.fi>
1257 For generic frontend server, reverse the order of
1258 "toolkit-supplied / application-supplied" strings sent as implementationId,
1259 Name and Version. Also, remove the spaces around the slash. This brings
1260 the GFS in line with the behaviour of ZOOM-C on the client side.
1262 Add function ZOOM_scanset_display_term.
1264 yaz-client shows scan displayTerm if present.
1266 Utility yaz-iconv is now installed by default along with the man page
1269 Extend configure check for OpenSSL to use pkg-config where available (such
1272 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1273 server to specify uid/gid/mask for socket using the format
1274 unix:[user=uid,][group=gid,][umask=mask,]file=path
1275 If file= is omitted the existing format is assumed, e.g.
1277 in which case the mask is 0666 (rw for everybody).
1279 Major restructure of YAZ source. All source in libyaz is in src directory.
1280 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1281 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1283 Added man page for utility yaz-marcdump (used to be called marcdump).
1284 yaz-marcdump is installed by 'make install'.
1286 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1287 of incoming package failed.
1289 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1291 Change prototype of odr_perror: add const to message string.
1293 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1295 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1296 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1297 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1298 DNS lookup. There should not be any compatibility problems with this
1299 assuming that blocking=1 or 0 is used.
1301 Fix bad reference in UNIX comstack in function cs_addrstr.
1303 Fix for compilation on AIX.
1305 The generic front-end server (server/seshigh.c) now supports returning
1306 Init diagnostics to the client in User-information-field, in
1307 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1310 --- 2.0.4 2003/09/04
1312 Allow any CQL relation (not just all,any,exact,scr).
1314 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1315 that features the same UI.
1317 Implemented command update0 in YAZ client which is equivalent to
1318 update but uses old of Ext Update ASN.1.
1320 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1321 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1322 Previously no OID was used for this info.
1324 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1325 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1326 returns 'malformed search term' otherwise.
1328 SortResponse member resultCount now set to NULL in sort handler of
1331 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1334 Add three new utility functions for translating OIDs between various
1335 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1336 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1337 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1338 char *oid_to_dotstring(const int *oid, char *oidbuf);
1339 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1341 Reverted modifications for ES Update definition for z_IU0Update
1342 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1343 is back to YAZ 2.0.2.
1345 String value attributes for CCL parser.
1347 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1348 which their FirstSearch server returns in Init responses, sometimes
1349 carrying useful diagnostic information when Init fails. This has the
1350 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1351 "z39.50/oclcui.asn", where its definition is somewhat different from
1352 what OCLC document on their web-site, as required to interoperate with
1355 Support for anonymous authentication in yaz-client. Use the command
1358 * Fix the OID of the Index Data-local "admin" Extended Service from
1359 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1360 the 1000, which indicates a locally-defined OID, was a mistake.
1362 --- 2.0.3 2003/06/20
1364 Fix CCL directive @case handling so that it affects string match for
1365 both CCL keywords and qualifiers.
1367 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1368 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1369 Decoder has been updated with ASN.1 changes as listed in
1370 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1371 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1372 z_IUUpdate, remains unchanged.
1374 ZOOM_record_get may now return a record in a specific character set.
1375 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1376 "from" is the character set of record as returned by target. "to" is
1377 the character set to be returned. If omitted, "to" is UTF-8.
1379 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1381 New ODR utility, odr_getelement, which returns name of element for
1382 which encoding/decoding failed.
1384 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1385 in cases where a required element was omitted.
1387 Bug fix: some MARC8 sequences were not converted.
1389 New ZOOM option "step" which specifies number of records to be
1390 retrieved in one chunk. Used in conjunction with "start" and "count".
1392 SRW support for yaz-client. Use scheme http: to use it, e.g.
1395 yaz-client no longer does (un)intelligent character set conversions
1396 by default. Can be enabled with charset and marc_charset commands.
1398 xmalloc trace fix for 64-bit systems such as DEC alpha.
1400 Solaris 2.6 compile fix.
1402 New function, cql_strerror() translates SRW error codes, as returned
1403 by cql_transform_error(), into human-readable English strings. Used
1404 in yaz-client diagnostics when appropriate.
1406 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1407 converts it into a type-1 query which is sent to the server. This
1408 makes CQL available for use with all Z-servers, as opposed to the tiny
1409 minority that can handle CQL queries themselves.
1411 --- 2.0.2 2003/04/28
1413 New Debian package layout similar to the Redhat Package layout.
1415 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1416 and search result respectively.
1418 --- 2.0.1 2003/04/25
1420 Redhat package is now several packages: libyaz (runtime libraries),
1421 libyaz-devel (development and documentation, and yaz (utility programs).
1422 Package spec file by Morten Bøgeskov.
1424 New member 'schema' in struct bend_fetch_rr which the name of requested
1425 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1426 handler MAY set this to reflect the schema of the returned record.
1428 New member 'display_term' in struct scan_entry. GFS now sets member entries
1429 and allocates scan entries to be filled by user scan handler. In previous
1430 version, entries member was allocated by the scan handler. That still works,
1431 but the GFS will ignore member display_term - assuming it was NOT set by
1432 the handler. The fact that the GFS now allocates the entries both allows
1433 for new members and makes a scan handler easier to write.
1435 Fix CQL lex buffer overflow.
1437 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1438 SRU default recordPacking is string.
1440 SRU protocol support for frontend server.
1442 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1444 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1446 Added scan for the ZOOM shell (zoomsh).
1450 * String Identifers for Schemas (Amendment 5).
1451 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1452 Old definition for schema
1453 Odr_oid *schema; /* OPT */
1458 Z_InternationalString *uri;
1459 #define Z_Schema_oid 1
1460 #define Z_Schema_uri 2
1463 * resultCount parameter to Sort Response (Amendment 1).
1464 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1466 Support for SRW 1.0 over HTTP. This is an optional feature and
1467 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1470 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1471 on the same port. SRW SearchRetrieveRequests are mapped
1472 to bend_init,bend_search,bend_fetch,bend_close.
1474 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1476 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1477 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1479 ZOOM connections are SRW based if schem http is used for hostname
1480 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1481 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1483 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1484 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1485 distance=n, order=true/false, relation=le, prox unit=word. If
1486 n is omitted, distance 1 is used.
1488 Fixed problem with C compiler include path in wrong order.
1490 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1491 on Solaris. Patch from Ko van der Sloot.
1493 New MARC decode API. All new functions operate on a yaz_marc_t
1494 handle. The most important new functions are: yaz_marc_create,
1495 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1496 decode and destroy respectively. Decoder can produce formats
1497 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1498 include/yaz/marcdisp.h.
1500 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1501 to UTF-8, UCS-32, wchar_t or Latin-1.
1503 * Prototypes for yaz_iconv_-functions moved to separate header
1504 include/yaz/yaz-iconv.h.
1506 Make a few private functions 'static' in unix.c. This prevents
1507 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1509 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1510 are set when Init Response is received.
1512 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1513 but returns diagnostic set as well.
1515 New function yaz_strerror which is a portable wrapper for
1516 strerror/strerror_r/GetLastMessage.
1518 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1519 is returned for MARC. If type is "oai", then OAI MARC is returned.
1521 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1524 --- 1.9.2 2002/11/26
1526 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1528 Fix bad race conditions on SIGTERM and terminate gracefully in
1531 Move retrieval (data1) module to Zebra since nobody seems to be
1534 Add GRS-1 render for ZOOM using same format as yaz-client.
1536 --- 1.9.1 2002/10/05
1538 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1540 Fix broken ESpec handling in data1 module.
1542 SGML reader parses comments and makes them part of the data1 tree.
1544 Added several type casts so that YAZ compiles as C++ code.
1546 ZOOM didn't handle PDU encoding failures properly.
1548 Added more Bib-1 diagnostics (approved extensions).
1550 GNU configure: better check for iconv.
1552 More portable use of accept, getpeername. Check for socklen_t. Use
1553 int/size_t if socklen_t is not defined.
1557 PQF parser rejects bad queries - including those with extra
1558 characters in them. PQF parser used to silently ignore that.
1559 Cleaner API for PQF added, which allows you to get detailed
1560 error information for bad queries (see yaz/pquery.h).
1562 Fixed bug in ZOOM_record_get for type "database".
1564 Implemented mini iconv library supporting conversions between
1565 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1567 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1569 --- 1.8.9 2002/08/20
1571 Fixed ZOOM C record cache so that preferredRecordSyntax and
1572 elementSetName is used to check for already fetched records.
1574 --- 1.8.8 2002/08/02
1576 Added three members in bend_initrequest structure to facilitate
1577 character set negotiation.
1579 Fixed a bug in frontend server that could cause indefinite
1580 loops under rare conditions.
1582 Revised character set utilities (charneg.h) so that encoding
1583 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1585 For PQF, directive @term <type> sets term type for Scan/Search.
1586 Here <type> is general, string, numeric, null. The term type
1587 is inherited - just like @attr.
1589 New call odr_set_charset that sets character set conversion for
1590 international-strings on a ODR stream. Prototype is:
1591 int odr_set_charset(ODR o, const char *to, const char *from);
1592 The InternationalString is still represented as C string in YAZ
1593 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1594 won't). On the protocol level, you can use any encoding.
1596 Support for UNIX sockets in ZOOM.
1598 Solaris recv sometimes returns errno == ENOENT. It is treated as
1599 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1601 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1602 both client and server. Code by Morten Bøgeskov.
1604 --- 1.8.7 2002/05/22
1606 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1607 that they can be used directly from Visual Basic. You must recompile
1608 your windows APP if you're using ZOOM.
1610 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1611 Commands "lang" and "charset" sets language and character set respectively.
1612 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1613 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1615 Attributes from multiple CCL fields may be OR'ed rather than merged
1616 using directive "@field or". Fields are still merged by default -
1617 equivalent to "@field merge".
1619 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1622 Fixed bug in zget for parameter ExtendedServicesResponse.
1626 --- 1.8.6 2002/03/25
1628 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1630 Client displays USR.1:SearchResult-1 (hits per term).
1632 Additional Search Info for search in Generic Frontend Server.
1634 Fixed CCL parsing of "field=s".
1636 WIN32 installer - using the excellent NSIS software from nullsoft.
1638 Fixed CCL parsing of "field = - <number>".
1640 Added function yaz_marc_decode that decodes MARC for line mode
1641 display or XML (similar to that used by JZKit).
1643 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1644 Z39.50. But ISO/ILL was, however.
1646 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1647 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1649 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1650 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1652 --- 1.8.5 2002/02/03
1654 New YAZ client features: Command completion and new commands:
1655 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1656 Code provided by Jacob Poulsen.
1658 New call oid_trav, that visits all registered OIDs via callback.
1660 Function ZOOM_record_get now returns const char pointer rather than
1661 void pointer. It saves a lot of type casts.
1663 For YAZ client, command "auth" now allows you to set authentication
1664 in IdPass style. It is enabled when three tokens are given - order
1665 is user, group and password.
1667 Fix memory leaks in MARC record handling for ZOOM.
1669 New option for YAZ client, -k <kilobytes> that sets
1670 maximum record size. Similar to -k option for generic frontend
1671 server and yaz-ztest.
1673 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1675 Prefix query parser reports "fail" when bad attribute set is given.
1677 Fix in MARC decoder. Proximity logging. Fix for attribute set
1678 in scan handler for server. Patches by Shigeru Ishida.
1680 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1683 Configure option --with-openssl=<dir> now works when a directory is
1684 specified. Patch provided by Morten Bøgeskov.
1686 New option for YAZ client, -u <auth>, that sets authentication.
1688 ZOOM fix: error information was sometimes "missing", since error
1689 was cleared/reset too when it shouldn't.
1691 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1693 --- 1.8.4 2002/01/04
1695 Scan for ZOOM API. New object ZOOM_scanset. New functions
1696 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1697 ZOOM_scanset_destroy.
1699 New ZOOM function, ZOOM_connection_last_event, that returns type
1700 of last event (such as "receive data", "send data", "apdu received",
1703 New ZOOM option, schema, that specifies schema for retrieval.
1705 New CCL feature. Qualifiers can be aliases for one or more
1706 other qualifiers (if more than one is given, OR is used).
1708 ZOOM uses named result sets if target supports it.
1710 Two new YAZ client commands: . (dot, which sources a script of YAZ
1711 client commands), and ! (to execute shell command.). Implemented
1714 Working on Debian packages.
1716 --- 1.8.3 2001/11/19
1718 YAZ client enables named result sets only if target supports it.
1720 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1722 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1723 with key="host" to get same result.
1725 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1726 Function Z3950_resultset_record(s) returns references to records
1727 "owned" by resultset. To become owner use Z3950_record_clone.
1729 Function z_ext_record handles Extended Services. Thanks to
1732 --- 1.8.2 2001/11/12
1734 CCL Parser fix: ignore token comma when dealing with and-lists.
1736 Documentation updates for COMSTACK.
1738 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1739 Changed prototype Z3950_records. For some functions, int parameters
1740 were changed to size_t.
1742 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1745 New MARC decode/display function, marc_display_exl, which properly rejects
1746 non-ISO2709 records. YAZ client uses it.
1748 --- 1.8.1 2001/10/29
1750 Fix bug: local attribute set wasn't set correctly in PQF strings.
1754 * Old Z39.50 codecs no longer supported.
1756 Added ZOOM C binding. See http://zoom.z3950.org/
1758 Renamed states for COMSTACKs to avoid confusion with events.
1760 Implemented cs_look and proper cs_rcvconnect.
1762 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1764 Configure detects POSIX threads on OpenBSD.
1766 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1767 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1769 When error is returned from present handler, non-surrogate diagnostic
1770 is returned in present response (and fetch handler is no longer called).
1772 * Minor adjustments to pquery parser (PQF). Token characters may be
1773 escaped by using backslash (C-style).
1775 PQF parser allows string attribute values to be specified. For @attr,
1776 non-numeric characters after the equal-sign are treated as strings
1777 (e.g. @attr 9=title).
1779 CCL trunction character may be defined (@truncation in file)
1781 * function zget_ExtendedServicesRequest sets waitAction to
1782 waitIfPossible (was wait).
1784 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1787 CCL operator names may be set in field definition files (CCL_bibset).
1788 See ccl/bib1 for an example.
1790 Fixes in ASN.1 compiler for C++ compatibility.
1792 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1793 and "op_or" to avoid conflict with C++.
1795 Fixed problem with GNU readline detection on Redhat 7.0.
1797 Added step-size for Scan backend handler.
1799 Fixed bug that made the frontend server crash when no attribute
1800 set was specified for scan.
1802 Front-end server automatically switches to original working directory
1803 when installed as an NT service. Previously -w had to be specified to
1806 Added extended attributes for retrieval module (data1), so that data1
1807 records carry d1_readXML/SGML attributes. d1_read also supports
1808 null-data rules ( <tag/>)
1810 On UNIX when POSIX threads are available, a separate library libyazthread
1811 is created. Programmers should link with that library and the yaz library
1812 when using threads. The reason for the split was that some applications
1813 on Linux, such as Apache, doesn't work well when using shared objects that
1816 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1817 (or any frontend server) in SSL mode by specifying ssl: followed by
1818 address. Only tested on UNIX.
1820 Added feature for CCL module. Virtual structure s=al or s=ol generates
1821 and-list and or-list respectively instead of phrase search.
1825 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1826 log_mask_str. This was done to avoid name conflicts with other libraries
1827 (such as other PHP extensions).
1829 Added raw OID member for preferred record syntax (request_format_raw)
1830 and returned record syntax (output_format_raw) for backend fetch method.
1832 Config file yaz-config now accepts options so that it returns specific
1833 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1835 Shared library support for UNIX using GNU libtool.
1837 * Modified backend interface. Request/Response struct's replaced by
1838 one read/write C struct. For example bend_fetchrequest and
1839 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1840 Every handler - even search has to be registered in bend_init
1841 handler. This means that the YAZ library no longer refers to
1842 external functions and it makes it possible to make the whole
1843 thing a single DLL/SO.
1845 Added Segment handler for backend server.
1847 Added Zmbol/Zebra administrative functions to YAZ client.
1849 Threaded frontend server on UNIX (when POSIX Threads are available).
1850 Starting the server with option -T enables multi-threading.
1854 Added configure option --enable-comp/disable-comp to control use
1855 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1856 located in sub directory asn.
1858 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1859 in ${exec_prefix}/bin along with the other programs yaz-client and
1862 GNU automake used to maintain makefiles.
1864 Added several OID's.
1866 Changed retrieval module so that we can load records with no abstract
1867 syntax defined. Tagpaths in these records are fully composed of string
1870 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1874 On UNIX, the generated makefile now supports a proper 'make install'.
1875 The prefix can be set via GNU configure to set the install location
1876 (default is /usr/local).
1878 * YAZ programs client and ztest were renamed to yaz-client and
1879 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1880 locations, such as /usr/bin,/usr/local/bin,etc.
1882 * YAZ Header files were moved from include to include/yaz. YAZ Header
1883 files are referred to as include <yaz/log.h> rather than <log.h>.
1884 The YAZ include path (-I ..) is therefore the same as before. Programmers
1885 should update their #include statements or use -Ipath/include/yaz
1886 instead. The main motivation for doing this change is that YAZ header files
1887 can be installed in "standard" locations /usr/include,/usr/local/include
1888 without introducing conflicts, since ALL YAZ header files are stored
1889 in subdirectory yaz (under /usr/include for example).
1891 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1892 rather than project/workspace files. We switched because project files
1893 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1896 Changed name of logging function, logf, to yaz_log, to prevent name
1897 clash with some math-log functions. The YAZ header log.h defines logf
1898 to yaz_log (#define) so there should be no incompatibilities by this
1901 Added bend_start/bend_stop handlers for server. These handler are
1902 called on start/stop of server. For windows they are called whenever
1903 a service is started/stopped.
1905 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1906 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1907 in util/yc.tcl. The auto-generated C code structures are, in a few
1908 cases, incompatible with the old decoders. There are differences in the
1909 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1910 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1911 The preprocessor variable ASN_COMPILED is defined when the compiled
1912 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1913 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1914 wish to use the old encoders/decoders you can specify --disable-yc
1917 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1918 version so that it supports both new - and old version of DB Update
1920 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1921 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1922 change. The name parameter can be set to 0 in which no name is specified
1923 for the construction. The macros odr_implicit and odr_explicit sets name
1924 parameter to zero for the construction involved. New macros
1925 odr_implicit_tag and odr_explicit_tag are similar to the others,
1926 except that a name parameter is added. For programmers' that don't use
1927 ODR they probably only need to change the call to z_APDU and z_External.
1929 Added access control facility by interfacing the TCP wrapper library.
1930 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1931 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1932 name of the daemon and enables the access control as specified in
1933 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1935 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1936 den Dool <H.M.vdnDool@kub.nl>.
1938 Added reference ID parameter to most functions in server API - refer
1939 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1941 Changed name of ccl library to libccl.a (was ccl.a).
1943 Fixed bug in decoder for Explain (Category TargetInfo).
1945 Added support for GNU readline in client. Thanks to Jacob Poulsen
1946 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1948 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1949 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1950 IMPLEMENTATION! This change was made to the development version before
1951 the ZIG decided to retract the amendment. If any users MUST be
1952 compatible with the original Update definition, PLEASE CONTACT US, and
1953 we will include a separate definition corresponding to the old Update
1954 ES. Note that because of the change to the ASN.1 of the
1955 TaskPackageRecordStructure we cannot define a single structure that
1956 will support both versions.
1958 * Added const modifier to buffer parameter for some ODR/BER encoding
1959 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1960 completeWAIS, odr_dumpBER.
1962 Fixed bug in client.c which caused a crash when a scanResponse didn't
1963 contain positionOfTerm.
1965 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1966 * will cause an error in a client if a non-YAZ target sends both a
1967 * list of Scan entries and non-surrogate diagnostics.
1969 Retrieval module enhancements. Tag sets may be typed in the reference
1970 to it. From the .abs-file the "tagset" directive takes a third optional
1971 integer type for the tag set referenced. From a .tag-file the "include"
1972 directive takes a third optional type as well. The old "type" directive
1973 in the tag set itself is still recognized but acts as the default type
1976 Backend interface change. Individual Scan terms returned from bend_scan
1977 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1978 in include/backend.h.
1980 Retrieval module enhancements. Multiple tag sets and attribute sets may
1981 be specified in abstract syntax specs. Revised the error/warning for
1982 logging messages reported by the retrieval module when reading the
1985 Object Identifier system (oid_..) changed. The API is backwards
1986 compatible but the oid-routines now allocates new OID's when needed.
1987 Raw OID's may be specified in oid_getvalbyname.
1989 YAZ now uses GNU configure to generate Makefile(s).
1991 * Minor changes in some of the member names of DeleteResultSetRequest and
1992 DeleteResultSetResponse. See include/proto.h.
1994 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1995 and added member 'languages' in TargetInfo (which was missing).
1997 Changed the way attribute sets are handled in the retrieval
1998 module. These are now cached, just like the abstract syntaxes
2001 Changed YAZ so that it links with compiled ASN.1.
2003 Added Explain-schema definitions and mapping routines. The following
2004 Explain categories have been implemented: AttributeDetails,
2005 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2007 Fixed minor bug in Windows version of Server Library.
2009 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2011 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2013 Added EXTERNAL: UNIverse Resource Report (non-standard).
2015 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2016 ENUMERATED and SET OF.
2018 * Added 'const' to some of the char pointer arguments for the
2019 functions, data1_read_node, data1_getelementbytagname,
2020 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2023 Fixed bug in data1_insert_taggeddata - the last_child member of
2024 parent wasn't initialised.
2026 * Changed data1_read_record and data1_read_node so that the supplied
2027 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2028 doesn't refer to any parts of the "SGML"-buffer.
2030 Fixed bug in server library (Windows version of statserv_remove).
2032 * Changed code so that it compiles as C++. The type definition
2033 of Odr_fun which is a member of Odr_arm was changed. The result is,
2034 that an explicit typecast is needed for the fun pointer when
2035 using Odr_arm - as in:
2036 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2038 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2040 Implemented the new structured date and time definition as approved
2041 by the ZIG. Added schemaId element to the specificTag in Espec-1
2042 (also approved at the last ZIG). Thanks to RVDM.
2044 Added some Object identifiers (RVDM).
2046 Changed the Update Extended Service (RVDM).
2048 Added command "refid" to client which specifies referenceId for
2049 the following requests.
2051 Implemented extended service handling for server. See ztest.c
2052 for an example as well as backend.h. New handlers are registerd
2053 in the Init handler.
2055 * Changed interface for sort in server.
2057 Added new members to statserv_options_block. It allows a server
2058 to read options from another source than just the command line. Thanks
2059 to Charles Woodfield.
2061 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2062 renamed to zboolean. Some C++ compilers complained about the name.
2064 Minor changes to gils.abs. Added index 's' (sort) on title
2065 and date/time-last-modified.
2067 --- 1.4pl2 1998/1/30
2069 Fixed bug in server library regarding inetd mode (-i). This bug
2070 was introduced by release 1.4.
2072 --- 1.4pl1 1998/1/29
2074 Added sort facility in client and backend server interface.
2076 Fixed problem with dependencies in Makefile(s).
2078 Fixed bugs for encoders/decoders of extended services and
2081 Implemented sub-tree feature for schemas. Sub-trees are
2082 referenced in *.abs-files. See explain.abs for an example
2083 of the use of this feature.
2085 Modified bib1.att; local attributes for ANY didn't include
2086 ANY itself (only affects use of the retrieval module).
2088 Fixed bug in plain SGML reader in function data1_read_node:
2089 tags with prefix "var" was incorrectly interpreted as variants.
2091 Added feature "sub-schemas" to enable references to - and definitions
2092 of - group of elements.
2094 * Removed member parent from type data1_element (in data1.h).
2096 Implemented function odr_nullval() that returns the value of
2099 * Removed member num_children from data1_node (in data1.h).
2101 Made NT service interface part of the server library. The
2102 function statserv_main uses the NT service when required and
2103 calls the statserv_start / statserv_close routines.
2105 Routine zget_SearchRequest and zget_PresentRequest fills
2106 resultSetName/Id member with "default" instead of "Default".
2108 Fixed memory leak in server. Request queue member wasn't freed.
2110 Fixed nmem_exit so that memory is freed.
2114 Revised the CCL parser utility to be thread safe.
2116 Added function, oid_ent_to_oid, to replace the function
2117 oid_getoidbyent, which is not thread safe.
2119 * Added nmem_init and nmem_exit to initialize and release
2120 NMEM resources. Function nmem_init should be called once in the
2121 initial thread before NMEM/ODR is used. statserv.c and client.c
2122 have been changed accordingly. The change was necessary to make
2123 NMEM thread safe. The NMEM memory pool is shared amongst threads
2124 in a process. Unix-based applications will still work fine without
2127 Added NT Services interface for the the Z39.50 (statserv) Server.
2128 Refer to the ztest.c source on the usage.
2130 Windows 95/NT port using MSVC5.0. Project files are included in the
2133 * Defined new 'global' handle for the retrieval (data1) system. The
2134 new handled, data1_handle, describes the state of the data1 system.
2135 This handle is passed as first argument to virtually all
2136 data1 related routines. The functions data1_create and data1_destroy
2137 creates and destroys a data1 handle respectively.
2139 Added ODR encode stream member to all backend request structures
2140 init, search, scan etc. This stream should be used to allocate all
2141 memory used for the response when thread safe operation is needed.
2143 Changed the comstack utility, cs_addstr, to be thread safe. The
2144 returned hostname string returned by the function is now part the
2147 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2148 function. The cs_straddr takes a COMSTACK handle as argument, so this
2149 function must be used after cs_create and before bind/connect.
2150 This function is thread safe.
2152 Moved test server to 'ztest' directory - generic server code still
2153 in 'server' directory.
2155 Made prefix query (pquery.c) utility thread safe.
2157 Added new function modifier YAZ_EXPORT to 'export' public DLL
2158 functions when using windows (see include/yconfig.h).
2160 Added definitions to the OID database (util/oid.c) (RVDM).
2162 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2164 Added call to ccl_rpn_delete in client program.
2166 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2167 release of RPN structure.
2169 Added support for C++, headers uses extern "C" for public definitions.
2170 With input from RVDM.
2172 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2173 Thanks to Ronald van der Meer (RVDM).
2175 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2177 Added support for private extensions to the OID database
2178 (oid_setprivateoids()). Thanks to RVDM.
2180 Added optional, physical ANY (key replication)
2182 Fixed null-reference problem in GRS-1 output filter.
2184 Proximity operator added to Prefix Query Format (PQF).
2186 In test client command "base" accepts multiple databases.
2188 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2192 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2194 Smallish bug-fixes in the new encoders/decoders (explain).
2196 Bug fixed in DeleteRequest.
2198 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2200 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2202 Added SOIF syntax (using private OID for now) to retrieval module and client.
2204 Added Update extended service.
2206 Added SearchResult-1 additional info structure.
2208 Added optional CCL (ISO8777) interpreter as separate module. Available
2211 --- 1.2 1996/6/10 (1st anniversary release)
2213 Added Summary record syntax. Lightly tested.
2215 Added OPAC record syntax. Untested.
2217 Added ResourceReport service encoders/decoders. Untested.
2219 Fixed bug in z_Unit - wrong tagging on unitSystem.
2221 Fixed bug in the DiagRecs decoder.
2223 Added options for max PDU size and session timeout to frontend-server.
2225 Added documentation of query-language parsers and other supporting utilities.
2227 [frontend-server] Added Attribute set to the bend_scanrequest API.
2229 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2230 surrogate diagnostics were generated.
2232 [retrieval] Allow multiple local values for attribute.
2234 [retrieval] Allow multiple attributes per element in .abs files. index type.
2236 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2238 --- 1.1pl2 1996/4/10
2240 Minor changes, mostly specific to Zebra's requirements (retrieval)
2244 Repaired bug in frontend server when running multiple listening
2245 endpoints in dynamic mode.
2247 z_External() now won't break if a known, ASN.1 value comes encapsulated
2248 in an octet-string. The value will pass through unmodified in an Odr_oct.
2250 Added a bit of code to the demo client to decode & display
2251 ASN.1-structured records represented in the octet-aligned branch of
2252 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2254 Added z_ext_getentbyref() to the ASN module. Doc updated.
2256 * Completed the SCAN definition in the ASN module. This may break SCAN
2257 code based on older YAZ-versions at compile-time. The fix is easy -
2260 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2261 under the SCAN definition. Remember to initialize this, server-people.
2263 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2264 that this does not extend to ODR and ASN.
2266 Comstack allows insertion of established socket (primarily for
2267 inetd-operation of servers). Doc updated.
2269 Front-end server can now start from the inetd in TCP mode. Doc
2272 --- 1.0pl4 1996/1/24
2276 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2277 the rank and record number.
2279 Adjustments to the frontend server.
2281 Fixed diagnostic BER dumper. It ignored the file argument.
2285 Various changes to retrieval module.
2287 Changed the union discriminators of the protocol files from enums to
2288 ints paired with #defines.
2290 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2293 *Changed operator in the RPN structure to 'roperator', again to avoid a
2296 Fixed problems in Explain decoders/encoders.
2298 --- 1.0pl2 1995/12/6
2300 Memory bug in log module fixed.
2302 --- 1.0pl1 1995/12/5
2304 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2306 Bug in Explain DatabaseInfo module fixed.
2308 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2312 The shift to v1.0 signals that we now consider the *core* functionality
2313 of YAZ reasonably stable (the core being more or less equivalent to
2314 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2315 tested (Explain not at all - though that will happen soonish).
2317 Minor changes to code to support Windows port.
2319 Various minor changes after we're getting to use GRS-1 & co. more.
2321 Added Espec-1 format.
2323 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2324 of the protocol and it cannot be selected when encoding (maps into 'string'
2325 when decoding). Needed to talk to some servers.
2327 Demo client can request simple element set names.
2329 Added Diagnostic Format encoders/decoders.
2331 Added simple Close handling to frontend server (no hooks for resource
2332 reporting yet), and demonstration client.
2334 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2336 --- 1.0b3 1995/08/24
2338 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2339 handled incorrectly when records were requested in the searchResponse. This
2340 will only affect you if you use the frontend-server.
2342 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2343 Test-client will ask for and print GRS1. Ztest will return dummy records
2346 Added Explain encoders/decoders to the service-level API. Untested.
2348 Added Extended Services: Item Order encoders and decoders to the Service-
2349 level API. Untested. We could use a recent copy of the pertinent bits
2350 of the ILL protocol to add those bits.
2352 Added diagnostic format 1 encoders/decoders to the service-level API.
2355 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2356 odr_cons.c, which causes a more correct output.
2358 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2359 was always set to 0 when no records were requested in the searchRequest.
2361 * Added better external-handling. This shouldn't harm old code that
2362 *encodes* externals. It can break code that looks for a
2363 'single-ASN1-type' representation, since those types that are known
2364 are now decoded immediately. Look at the SUTRS sample code in
2365 seshigh.c and client.c. Documentation updated.
2367 Handling of structured records in bend_fetchresponse. Length -1 marks
2368 structured record, type is deduced from format field.
2370 --- 1.0b2 1995/06/27
2371 Fairly quick maintenance release to add SUTRS support.
2373 Fixed handling of SUTRS records in the demonstration client.
2375 * Added format field to the bend_fetchrequest and bend_fetchresponce
2376 structures of the backend API (frontend server). When the record is
2377 returned, the value of the format field is mapped to an OID. The
2378 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2379 of the record. The special value VAL_NONE in the bend_request means
2380 that no specific format was requested by the client. Documentation
2381 updated accordingly. Test server (ztest) will return a fixed dummy
2382 SUTRS record if your client requests SUTRS.
2384 Documentation updated accordingly.
2386 You can now set external libraries and RANLIB support in the top-level
2390 First public release.
