3 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
4 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
6 ZOOM C now interprets databaseName option for ZOOM connection as path
9 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
11 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
13 Dummy Libxml2 types no longer defined in headers of YAZ'.
15 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
20 Various ODR chapter fixes.
22 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
24 Added missing source for Windows compilation, mutex.c.
26 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
28 For SRU connections in ZOOM all records up to "count" are now fetched.
30 Fixed crash in generic frontend server (and yaz-ztest) which occurred
31 in Windows due to bad error handling for Libxml2.
33 Added facility for sending arbitrary records (ASN.1 any) using
34 ZOOM C's Extended service update. Patch by Sam Reynolds.
36 New options for ZOOM C's connection, logapdu which makes ZOOM log
41 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
45 Fixed memory violation that could occur when decoding UTF-8. This bug
46 was only present in 3.0.30 of YAZ.
50 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
51 GNU TLS is used by default (if found).
53 yaz-ztest returns OPAC records if a client asks for OPAC.
55 Improved speed of MARC-8 encoding.
57 Added support for lossy and loss-less MARC-8 encoding.
59 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
61 Added new Windows Service wrapper (sc).
63 yaz-client's itemorder command may now send a file.
65 Fixed yaz-marcdump to allow the use of NS prefix for record element.
67 Added new function yaz_log_xml_errors.
69 Allow (but warn) unknown XML attributes in MARCXML parsing.
71 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
73 The UTF-8 to MARC-8 conversion now uses a different set of characters
74 for Greek symbols. Bug #2120.
78 Added yaz_daemon (daemon.h).
80 Fixed bug #2068: pkg-config trouble
82 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
86 Document --with-xml2 option.
88 Added OPAC XML XSD (etc/opacxml.xsd).
90 Allow glob mask for name attribute in retrieval element for the
91 generic frontend server's retrieval facility.
93 Changed yaz_poll_poll to return yaz_poll_except for all returned events
94 except POLLIN/POLLOUT.
96 Fixed error handling in cs_listen. Bug #2037.
100 Fixed version in yaz/yaz-version.h.
102 Fixed bug #2027: Crash when closing connection.
104 Changed configure so that ICU support is only enabled if only ICU
105 and Libxml2 is available (because the ICU chain is XML based).
107 --- 3.0.20 2008/01/15
109 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
110 is built. Only this DLL depends on the ICU runtime.
112 yaz-ziffy is no longer part of YAZ. It is distributed separately by
113 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
115 Changed license of CCL module to 'Revised BSD'. After consultation with
116 remaining members of the original EUROPAGATE consortium, we are re-issuing
117 the CCL module without a separate license. The software was developed by
118 Index Data as part of a research project. The special license was included
119 to help feed usage information back to the project consortium to support
120 project evaluation. At this time, the project consortium has long-since
121 disbanded, and the majority of the original principals have retired. At the
122 same time, we have significantly modified the software during the following
123 years, to the point where very practically no original code remains. To
124 simplify re-use of the software, we have contacted those members of the
125 consortium who could be reached, and agreed to re-issue the module as a
126 proper part of the YAZ package.
128 Tcl scripts uses /usr/bin/tclsh as preferred shell.
130 CQL closer to being version 1.2 compliant. CQL also allows free-form
131 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
134 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
135 bug could make Extended services handling crash in the ZOOM layer. This
136 bug was only present in YAZ 3.0.18.
138 --- 3.0.18 2007/12/19
140 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
143 yaz-marcdump reads and writes collection wrapped records.
145 Handle OPAC for record conversion module.
147 Fixes for ICU wrapper.
149 Allow ICU libs to be controlled with --with-icu .
151 --- 3.0.16 2007/11/12
153 Added yaz_poll which is a wrapper for select/poll. When poll is available
154 and non-buggy, it is used, by yaz_poll . This allows more than 1024
155 sockets to be in use.
157 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
158 functionality through an XML based configuration (ICU chain). This system
159 is useful for search facilities such as Pazpar2 and Zebra that needs to
160 perform tokenization of indexed material. The ICU code in a separate
161 library libyaz3_icu.a.
163 Added HTTP tunnel facility for COMSTACK, bug #1752.
164 This is a facility that allows a Web proxy, such as squid, to tunnel
165 Z39.50 traffic. This facility is "transparent" to must applications
166 using YAZ. It's enabled by using pseudo transport connect: followed by
167 the proxy address, followed by command, then follwed by he regular
168 "virtual" addresss. For example,
169 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
171 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
173 --- 3.0.14 2007/09/21
175 Fixed bad memory reference in ZOOM_record - cuased by member not being
176 initialized. This was a problem only in YAZ 3.0.12.
178 Fixed bug in conversion from MARC to XML: Non-XML characters in control
179 fields were not removed.
181 Changed the way C code is generated from codetables.xml. Made a MARC-8
182 conversion trie for each characterSet section rather than codeTable.
183 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
184 of codetables.xml from Larry Dixson, LOC. Bug #1464.
186 --- 3.0.12 2007/09/12
188 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
189 from ZOOM_record_error).
191 ZOOM C function ZOOM_record_get returns record schema for type="schema".
193 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
195 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
197 Better SRW-to-Bib-1 diagnostic mapping.
199 ZOOM C and yaz-client announces SRU version 1.2 by default.
201 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
204 Fixed in yaz_sru_decode to allow other version than 1.1.
206 --- 3.0.10 2007/08/22
208 Added support for SRU scan for ZOOM.
210 Added support for the use of the older versions or Extended Service
211 Update in ZOOM. To faciliate this, an option "updateVersion" may be
212 set to the version , 1=first, 2=second, 3=third. The third version is
213 what ZOOM C has used so far. And that, obviously, is the default.
215 Added support for CCL queries in Z39.50 queries sent to the GFS (and
216 therefore in Zebra and in SimpleServer-based applications). The new
217 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
218 qualifier file used to transform incoming CCL queries into Type-1 RPN,
219 which is passed into the back-end search callback function.
221 Added support for HTTP Basic authentication in clients: the SRU/W
222 codec encodes the username/password elements of the PDU structure
223 appropriately, and these may be set using the "user" and "password"
224 options in ZOOM-C applications (the same options that are used for
225 Z39.50 authentication).
229 Fixed bug #1208: SSL appears to be broken in ZOOM.
231 Fixed bug #1206: Libxml2 include path weirdness.
233 Added oid_name_to_dotstring.
235 Allow elementSetName to be specified for ZOOM C record update.
237 Allow waitAction to be specified for ZOOM C based for Extended Services.
239 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
240 syntax OID. Bug introduced in YAZ 3 series.
242 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
246 Fixed bug #1157: yaz-client does not read .yazclientrc from current
247 directory. yaz-client now reads commands from file given by option -f
248 if specified; then tries to read .yazclientrc in current directory.
249 Failing that, it reads .yazclientrc from user's home directory.
251 Added support for correlationInfo Note and ID for Record Update via
254 Added yaz-client command querycharset which specifies character set for
255 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
256 (termListAndStartPoint).
258 Charset ISO5428:1984 is an alias for ISO5428-1984.
260 Implemented a way to perform scan in a result set using Z39.50. This
261 is achieved by attaching the result set name in the characterInfo
262 (type InternationalString) of OtherInformation in the Scan Request PDU.
263 The result set is identified in the otherinformation by the new OID:
264 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
265 This allows for scan in result set and faceted search . Zebra did some
266 of this in the APT term using attribute type 8 and value being result
267 set. Using the OtherInformation approach for this is cleaner and easier
268 to work with in proxies and the like. This facility can be used in
269 yaz-client using new command setscan which takes a result set as first
270 argument, start position (APT) as second.
272 Changed decoding of SRU XML packed records to deal with servers that
273 have recordData with XML data with multiple root nodes. Also make
274 comparison for recordPacking case insensitive. Again, one server
275 returns "XML" where others return "xml".
277 For SRU responses allow Content-Type application/xml as well as text/xml.
281 Fixed bug in character set conversion of BER strings. Bug introduced
286 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
288 For OID class, use oid_class consistently.
290 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
293 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
294 character set for bibliographic information interchange". By Giannis Kosmas.
296 Added documentation on new OID API.
300 Changes to generic frontend server interface: added new member
301 'query_charset' for bend_initrequest structure. A backend init handler
302 should set this member to its native character set for query terms.
303 When defined, the frontend server logic will announce this character set
304 to a client if the negotiationModel bit is set by the client. All server
305 implementors are encouraged to specify this. If a backend server does not
306 specify this a warning is issued using yaz_log(YLOG_WARN,..).
308 Added CCL utility to remove terms (stop words) from resulting RPN
309 tree. This is handled by functions with prefix ccl_stop_words_ .
311 New ZOOM C option, "rpnCharset", which allows client-side conversion of
312 terms in RPN queries.
314 Clean-up the CCL API. Moved some internal structures from ccl.h to
315 private header cclp.h. Changed ccl_parser_create so that a Bibset must
316 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
317 This is replaced by ccl_parser_find_str which takes a string instead.
319 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
320 libyaz.la is the core of YAZ except the generic frontend server and
321 does not depend on POSIX threads anymore. libyaz_server.la is the
322 generic frontend server facilities and uses POSIX thread functionality
323 if available. The libyaz.la no longer depends on POSIX threads because
324 the number of global structures is limited. NMEM no longer re-uses blocks
325 between threads ; it simply free's memory immediately but allocates in
326 "large" chunks as usual. We don't expect any performance penalties
327 because of this. The yaz_log system is still using a global log_level so
328 caution must be taken when modifying it with yaz_log_init_.. +
329 yaz_log_mask_str. This, however, should not cause any trouble because
330 these functions are called during initialization of application code
331 anyway. `yaz-config --libs server` returns libs for server applications;
332 `yaz-config --libs` returns libs for non-server applications.
334 New OID database - with public definitions in oid_db.h. Removed old OID
335 database including the head oid.h and definitions such as enum oid_value
336 and struct oident. The new OID database uses the same string names as
337 before but the 'protocol' is gone. There are now only two representations
338 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
339 converts from string to OID; functions with prefix yaz_oid_to_string
340 converts the other way.
342 Change to emit_term() in CQL-to-PQF query translation: when a term has
343 the /regexp relation modifier, do not process it for leading and
344 trailing "^" and "*", which have quite different meanings in regular
347 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
348 write handlers no longer carries a 'last' parameter. This will make
349 yaz_iconv flush "less" characters. A flush is performed by call to
350 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
352 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
353 removed, because function yaz_query_to_wrbuf does the same.
355 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
356 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
358 Deprecated MARC utility functions removed.
360 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
363 Branch split: YAZ_2_1_55_branch
365 --- 2.1.54 2007/03/16
367 Fix to ZOOM-C so that transparent reconnection is properly handled on
368 connections that are in asynchronous mode.
370 Fixed compilation on OpenBSD 4.0.
372 Large strings in GRS-1 records are now properly displayed in yaz-client.
374 Added character conversion support for "advancegreek"; based on patch from
377 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
378 sequence is met. Before the error was not set so it would be unknown.
380 Adjust yaz-marcdump MARC reader so that it skips until record separator
383 --- 2.1.52 2007/03/07
385 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
386 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
387 fd_set structure used as a bitmask for the FDs to be selected on.
389 Using ACX_PTHREAD macro to check for POSIX threads.
391 Fixed have-vsnprintf check.
393 --- 2.1.50 2007/02/23
395 Fixes for configure on BSD. Bug #900.
397 Added snprintf/vsnprintf wrappers for systems that don't have
398 limits (heavens forbid).
400 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
401 created before all previous tasks were completed and removed from the
402 task queue, the new task could be removed by a mistake.
404 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
406 Implemented pass-through CQL-to-PQF conversions. Bug #861.
408 Fixed bug #832: Problem with MARC/charset in yaz-client.
410 Fixed bug #668: save command line history for yaz-client.
412 Fixed bug #830: pkg-config support.
414 --- 2.1.48 2007/01/23
416 Extended ZOOM result set options with two options that may be read by
417 a client: resultSetStatus and presentStatus with values as specified for
419 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
421 Fixed bug #827: Using SSL fails on Debian etch.
423 Fixed bug #826: Weird looking chars for set of MARC records.
425 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
426 that is treated as an ItemOrder with itemRequest being an XML document
427 external. The value of "doc" is the content.
429 Extended the GFS search facility. New member of bend_search_rr
430 'estimated_hit_count' signals that hits is known to be an estmate
431 (higher or lower than real hit count). New member 'partial_resultset'
432 signals that the search was partial (hit count is lower or equal than
433 real hit count). For Z39.50, the information is stored in resultSetStatus
434 member of SearchResponse APDU. For SRU, the information is signalled
435 via SRU diagnostic 59: "Result set created with valid partial results
438 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
440 --- 2.1.46 2007/01/13
442 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
444 Added ZOOM_connection_peek_event.
446 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
447 the following new functions:
448 ZOOM_event_nonblock, ZOOM_connection_process,
449 ZOOM_connection_get_{socket,mask,timeout},
450 ZOOM_connection_fire_event_{timeout,socket}.
451 The existing blocking event handler, ZOOM_event, is a wrapper for the
452 + blocking ZOOM_event_sys_{poll,select}.
454 Implemented function ccl_xml_config which parses XML version of CCL
455 configuration (bug #798).
457 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
459 Added timings utility (yaz/timing.h)
461 --- 2.1.44 2007/01/03
463 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
466 Fixed bug #779: Rotation of apdu.log fails.
468 Fixed for character set conversions:
469 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
470 Honor G1 set in MARC-8 decoding.
472 --- 2.1.42 2006/12/17
474 Fixed bug #775: char conversion does not handle Alternative UTF-8
477 Implemented function yaz_marc_read_line which parses MARC line format
478 records. There is a wealth of formats out there. So far, this function
479 reads line records produced by yaz_marc_write_line.
481 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
482 more generic and easier to remember(!) options: -i format and -o format
483 which specifies input format and output format respectively - where
484 format is one of "marc", "marcxml", "line", "marcxchange".
486 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
487 does not print anything except warnings for records.
489 For yaz-marcdump, added support for MARC split into files (-s) with a given
492 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
493 spec, at http://www.loc.gov/standards/sru/record-update/
494 This has changed the binary layout of the following structs:
495 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
496 bend_update_rr . Patch by Ko van der Sloot.
498 Added GFS utility function bend_assoc_is_alive which returns 1 if
499 association is still alive (client is connected); 0 otherwise (client
500 closed connection). This allows busy servers to stop working for
503 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
504 been a separate piece of software. This version of ziffy has been modified
505 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
507 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
509 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
510 Client code may now interrogate options such as "init_opt_sort" to
511 find out whether the server claims to support various options.
513 --- 2.1.40 2006/11/27
515 Added utilities yaz_{set,get}_esn to set/get element set name from
518 Removed the build of libyazthread.la. The libyaz.so is the threaded version
519 of YAZ and has been so since YAZ 2.1.10.
521 Implemented ZOOM_record_error which returns error information for
522 record (surrogate diagnostic).
524 --- 2.1.38 2006/10/31
526 Updates for SRU Update by Ko van der Sloot:
527 1. Changed name from "operation" to "action"
528 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
529 versions in the code, marked as 'backward compatible'.
530 3. Added diagnostics for SRU Update.
532 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
534 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
536 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
538 For GFS, fixed problem with SRU diagnostic 'First record position out of
539 range' being issued for 0 hits.
541 zoomtst10 part of Windows Build.
543 --- 2.1.36 2006/10/13
545 Implemented yaz_filepath_comp which splits a path into file path
546 components (required by Zebra 2.0.3+).
548 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
549 BSD inspired license until now so this should not have any real impact on
550 anybody. See http://www.opensource.org/licenses/bsd-license.php
552 Fixed bug #687: Missing log lines.
554 Fixed bug #678: CQL to PQF translation does not preserve double-quote
557 Fixed bug #689: SRU diagnostics to be added.
559 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
560 whether a connection is idle (no more work do do).
562 --- 2.1.34 2006/10/04
564 Change type of optval from long to int for invocation of setsockopt with
565 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
567 Added support for specifying the max log file size for the Generic
568 Frontend Server. The size is given with option -r.
570 --- 2.1.32 2006/09/21
572 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
574 --- 2.1.30 2006/09/17
576 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
579 Fixed bug in Generic Frontend Server that could cause a server to stop
580 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
582 For the generic frontend server, the maximum record size is used as maximum
583 size of incoming packages (SRU + Z39.50). The value until was previously
584 only used in Z39.50 Init negotiation and, later, in a session controlled
585 sizes of records returned. This is controlled using -k option. It can be
586 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
588 --- 2.1.28 2006/09/04
590 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
593 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
595 New option for yaz-marcdump -lpos=value which allows setting a portion
596 of MARC header to a certain value.
598 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
600 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
601 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
603 --- 2.1.26 2006/08/15
605 Fixed problem with SRU mode type (soap, get, post) for yaz-client
608 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
610 --- 2.1.24 2006/08/08
612 Fixed MARC ISO2709 encoding routines to deal with character set
615 Minor changes to GFS logging. Database included in search request log
618 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
619 cached/multiple records.
621 Shared libraries are built by default on Unix+configure.
623 Changed cql2pqf transformation to use a different evaluation order. The
624 new order is: always, relation, structure, position, truncation, index
625 and relationModifier. Old order was: always, relation, relationModifier,
626 structure, index, position, truncation. Note that the the latter ones
627 override former ones for identical attributes.. The new scheme means that
628 it is possible to override any existing attribute with a relationModifier.
629 And also that it is possible to override everything for the index rule
630 (except the ones listed in relationModifier). No order is perfect but this
631 one, we believe, covers more real cases.. The "always" should have been
632 called "default", since the attributes there can be overridden with all
635 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
636 compilation phase, but also for yaz-config --cflags output. This allows
637 us to have public headers with Libxml2 stuff in them . It should also,
638 eventually, make Libxml2 checks redundant in packages using YAZ, such
641 --- 2.1.22 2006/06/15
643 Changed SRU update structure bend_update_rr so that SRU diagnostics are
644 stored in uri, message and details.. Previously diagnostics were stored
645 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
646 compatibility.. but he's probably the only one affected, so.
648 Added support for CCL, compiled on the client side, in ZOOM-C. This
649 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
650 input; the resulting query objects can be used for for searching with
651 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
653 YAZ' configure searches for OpenSSL by default.
655 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
656 SL_CTX_use_certificate_file. See
657 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
658 for more info. Thanks to Ko van der Sloot.
660 --- 2.1.20 2006/06/02
662 Bug #600: SRU GET, POST support for yaz-client. Introduced
663 command 'sru' which selects method SOAP/GET/POST.
665 Allow missingValueAction to be specified for the sortspec string -
666 function yaz_sort_spec. By default, the missing value action is null.
667 Use ! to specify "abort". Use = followed by stringvalue to specify default
670 Ensured that Present-handler (if defined) is called in GFS before any call to
671 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
672 searchRetrieve requests.
674 Documentation for YAZ is now based on the Docbook XML/XSLT using
675 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
676 is no longer depending on jade/openjade or docbook-to-man scripts.
677 PDF is no longer part of the distribution - but can optionally be
678 made using DSSSL/jadetex or FOP.
680 Added retrieval handling support in Generic Frontend Server to support
681 conversion between MARC/XML as well as XSLTtransforms. See
682 etc/yazgfs.xml for an example.
684 Added Authentication support to Generic Frontend Server in SRU
685 mode. Authentication using HTTP Basic is supported, as is the use
686 of 'x-username' and 'x-password' parameters in the request itself.
688 Added support for a new character set MARC8s identical to MARC8 except
689 that it converts combined characters to single Unicode characters in the
690 Latin-1 range (when possible).
692 --- 2.1.18 2006/04/24
694 ASN.1 compiler 0.4: generates brief Doxygen file header for
695 generated .h/.c files.
697 Utility yaz_iconv now supports conversion to MARC-8.
699 New facilities for the MARC module. The reading - and writing of
700 content are separate methods for the yaz_marc_t handle. The following
701 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
702 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
703 format). Write functions have prefix yaz_marc_write_.. The existing
704 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
705 available. Removed support for OAI-MARC and simplexml (not the
706 simplexml from PHP5).
708 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
709 to be returned for this connection.
711 --- 2.1.16 2006/03/31
713 Allow multiple languages and charsets to be specified with
714 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
715 negcharset iso-8859-1,utf-8
717 Translation of proximity nodes from CQL into PQF now works.
719 Moved to automake 1.8, 1.9.
721 Added function yaz_log_set_handler which allows a log handler to be
722 installed. This handler will be called for all log messages. Output
723 to file is also produced; but that can be disabled by passing NULL
724 fname to yaz_log_init_file.
726 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
728 For SRW (including GFS), accept application/soap+xml as content-type
731 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
732 produces NO stylesheet reference even if a default stylesheet is specified
735 --- 2.1.14 2006/03/14
737 Updated Windows package to include yazd.dll + yazd.lib for the
738 Development component.
740 If the environment variable YAZ_LOG is set, then it is used as a
741 string indicating the default level of logging to use if not
742 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
743 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
744 used as before. So, for example, to omit warnings from YAZ logging,
747 cql_transform() now map structure and other attributes before indexes,
748 so that index-specific structures and other attributes can override
749 defaults. So now a combination of mapping specifications such as:
751 index.dc.date = 1=date-modified 4=5
752 does the right thing.
754 cql_transform() now also respects the "always" mapping specification,
755 which establishes an initial set of attributes to be used for all
756 terms except where overridden by more specific attributes associated
757 with the index, relation or modifier.
759 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
760 which mode to use; one of "post", "get" or "soap" (SRW, default).
762 Fixes for yaz_iconv routines: changed trie-based character set conversions
763 to use only non-negative values for bit fields due to Sun's C compiler not
764 supporting negative values.
766 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
767 sequences where not read correctly. Fix by Rustam Usmanov.
769 Updated win/makefile to use options, settings which makes things
770 compile with VS C 2005.
772 --- 2.1.12 2006/02/01
774 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
776 In ZOOM socket code, use select instead of poll on MacOSX.
778 ZOOM-C now support client-side compilation of CQL into RPN that is
779 sent to the server, enabling CQL to be used against all Z39.50
780 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
781 ZOOM_query object, and submit it using ZOOM_connection_search().
782 The CQL-to-RPN translation uses a configuration file, the name of
783 which must be specified in the Connection's "cqlfile" option.
785 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
786 function, which takes as its start-term parameter a ZOOM_query object
787 (which may have had either CQL or RPN set into it).
790 --- 2.1.10 2005/11/29
792 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
793 GFS to support this as well. Backend handler, bend_srw_update, does the
794 update work. Code contributed by Ko van der Sloot.
796 Allow retrieval of Search Result-1 information in ZOOM by the use of
797 options that are attached to a result set. ZOOM documentation updated
800 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
801 UTF-8 conversion. Patch by Raj Patel.
803 Added option -m to GFS to control formatting of timestamps in log file.
805 Added 'exit' as synonym for 'quit' in yaz-client
807 Added support for specifying SRW resultSetId + resultSetIdleTime in a
808 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
809 for the new members. Patch by Ko van der Sloot.
811 Added support for SRU POST. It is supported for content-type
812 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
814 Do not build the separate Multi-threaded (MT) library libyazthread.la.
815 Instead make the library libyaz.la multi-threaded. Threading as a whole
816 can still be disabled by configure option --disable-threads. Previosly,
817 with older GLIBCs there were problems with MT libs under Apache. This
818 has now been fixed a long time ago.
820 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
823 CQL module modified to be case insensitive for relations/indexes/operations.
825 Fixed bug in CQL transform code: incorrect value relationModifieder
828 Added 'show all' command for yaz-client which retrieves all results
831 Added new yaz-client, xmles, which takes a (private) OID and
832 a document to be sent as an extended service request.
834 Describe new yaz-client commands wait_response and set_auto_wait.
836 Increase TCP/IP listener backlog from 3 (which I am guessing was
837 copied from the SunOS manual entry way back when) so SOMAXCONN, so
838 that the socket will queue as many incoming connections as it's able
839 to handle ongoing connections. In other words, it will never now
840 refuse a connection that it would be able to handle merely because
841 it's not got around to accepting() enough of the pending connections
842 yet. This is the behaviour anyway under Linux, where the listen()
843 argument is ignored; but not under BSD and on systems such as
844 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
845 YAZ-based servers should now be uniform across operating systems in
848 yaz-marcdump uses 64-bit file access on some systems. This is enabled
849 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
850 This allows yaz-marcdump to read large MARC batches (>2 GB).
852 Modified all YAZ source files - except the source which is auto-generated
853 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
856 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
857 corresponding to the existing *_setl() function. These allow option
858 values containing arbitrary valuues.
860 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
861 ZOOM_resultset_sort() in new applications. Its behaviour is identical
862 except that it returns an indicator of whether or not the sort
863 criterion was accepted (0 for OK, -1 for invalid).
867 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
868 MARC output rather than returning "new" buffer.
870 yaz-client warns about unknown init options.
872 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
876 Added support for SRW sort in Generic Frontend Server. Patch
877 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
878 sortKeys - or NULL if none is provided.
880 Fixed bug #307: It was impossible to specify indefinite/no timeout
881 for ZOOM_event. Special timeout value -1 now means indefinite timeout
884 Added support for multiple languages and charsets to be specified in
885 ZOOM. Each charset/language is separated by a blank. If negotiation is
886 in effect in init-response, Option
887 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
888 Code based on patch by Vasiliy Osadchuk.
890 Fixed bug #306: infinite recursion that occurred when calling
891 yaz_log_level_init as the first call (before other log level or
894 Fixed bug in scan handling in front end server: if preferred-Position-In-
895 Response was non-present, a NULL pointer referece was performed.
899 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
900 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
901 now defined for all those error codes. So instead of putting 109 in
902 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
903 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
905 Modified the yaz-marcdump utility to skip garbage bytes between MARC
908 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
910 Program yaz-client now exits and produces an error message if multiple
911 Z39.50 servers are specified on the command line (none or one allowed
914 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
919 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
921 Fixed bug #272: Preserve spacing for CCL terms.
925 Added support for virtual hosts and multiple backend servers for
926 the YAZ frontend server. The configution is XML based and
927 support specificition of CQL to RPN mappings and explain information.
928 See section "Virtual Hosts" in the YAZ manual.
930 Extended OPAC display utility. OPAC display utility renders
931 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
932 to supplement yaz_marc_decode_wrbuf.
934 Fixed a bug in MARC decoder that could caused it to crash for some
935 invalid MARC records. More diagnostics and warnings where added in
936 XML output (warnings, etc are stored in comments).
938 --- 2.0.34 2005/02/08
940 Fixes for UNIX domain sockets. Bug #261.
942 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
944 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
945 Added yaz_marc_subfield_str which defines subfield lead string which is
946 used in YAZ_MARC_LINE format. Default string is blank+$. Added
947 yaz_marc_endline_str which defines end of fields string used in
948 YAZ_MARC_LINE format. Default string is newline.
950 Experimental support for MarcXChange. This format can be produced
951 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
952 http://www.bs.dk/standards/MarcXchange.xsd
954 Added yaz-client commands scansize that sets maximum number of
955 entries to be returned by scan.
957 --- 2.0.32 2005/01/11
959 Added support for SRW scan in yaz-client and Generic Frontend Server.
961 * Added whereInList member to SRW Scan Term.
963 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
965 Fixed NMEM system to return aligned blocks on the smallest boundaries
966 that are suitably aligned for all possible types on the particular
967 architecture YAZ is being built for.
969 --- 2.0.30 2005/01/04
971 Fixed numerious warnings that was issued with newer versions of GCC.
973 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
974 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
977 Make YAZ Generic Frontend Server slightly faster.
979 Enhance (and reduce) logging for Generic Frontend Server.
981 Revert YAZ log system so that it flushes every write operation
982 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
984 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
985 instead of LOG_, due to name clash with syslog(3). LOG_ are still
986 present. New applications should define YAZ_USE_NEW_LOG=1 - this
987 will effectively disable old definitions.
989 --- 2.0.28 2004/11/09
991 Added yaz_log_time_format which specifies log format using
994 Added yaz_log_module_level which returns mask for a module. Value
995 is non-zero mask a if module is enabled; zero if disabled.
997 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
998 in include/yaz/cql.h.
1000 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1002 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1004 Fixed bug #172: RPM builds does not enable SSL.
1006 Doxyfile.in part of dist. Doxyfile generated by configure.
1008 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1009 are given and the corresponding component does not exist.
1011 Extend CCL documentation in YAZ reference. Describe r=r.
1013 --- 2.0.26 2004/10/01
1015 Fixed MARC->MARCXML conversion to properly deal with
1016 fields, subfields, indicators having non-ASCII characters.
1018 Fixed MARC->MARCXML conversion so that ASCII control characters
1019 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1022 Added YAZ GFS support for conversion from Z39.50 surrogate
1023 diagnostics to SRW surrogate diagnostics.
1025 Bug fix: YAZ GFS did not return schema in explainResponse.
1027 --- 2.0.25 2004/09/30
1029 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1030 now converts recordSchema to elementSetName as well as schema URI.
1032 Fixed bug in COMSTACK that prevented HTTP request packages from being
1035 --- 2.0.24 2004/09/29
1037 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1038 does not require white-space before and after the dash in a range, e.g.
1039 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1042 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1043 due to new GCC removing "redundant" code.
1045 Added yaz-client commands scanpos and scanstep that sets preferred
1046 position and step-size for scan.
1048 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1050 Added CCL utility ccl_qual_buf which parses one or more CCL
1051 spec lines in a buffer.
1053 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1054 of name and value - ignoring empty lines and comments.
1056 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1058 Added odr_get_element_path which returns current element path for an
1059 ODR handle. This utility is useful in error handling or user-defined
1062 Added ODR_PRINT utility odr_set_stream which is is a more generic
1063 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1064 to a write function and pointer to close function. The close function - if
1065 non-NULL - will be called during odr_destroy.
1067 Fixed bug in CCL parser where truncation char was not removed from
1068 right side when truncation=both was in effect.
1070 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1073 --- 2.0.23 2004/08/11
1075 Fix buffer overrun in CQL parser when dealing with proximity (%).
1077 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1078 to UTF-8/UCS conversion is now only based on codetables.xml.
1080 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1082 --- 2.0.22 2004/08/06
1084 Add support for more "commit changes" in ZOOM (uses Extended Services).
1086 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1089 Yet another small fix for configure of SSL.
1091 --- 2.0.21 2004/05/14
1093 Fix SSL libs for configure when --with-openssl=DIR is given.
1095 --- 2.0.20 2004/05/10
1097 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1099 SSL comstack now uses yaz.pem certificate file on server side
1100 by default. Certificate filename can be configured by calling
1101 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1103 Fix bug regarding multiple calls to ZOOM_connection_connect.
1105 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1107 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1108 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1110 ZOOM now allows inspection of X509 peer certificate for verification.
1111 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1113 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1114 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1115 as "modular" but it simplifies things.
1117 Added cs_get_peer_certificate to that returns peer X509 PEM.
1119 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1120 NULL if SSL is unavailable.
1122 Documentation about MARC decoding tools.
1124 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1126 --- 2.0.19 2004/03/30
1128 Rename CHANGELOG to NEWS to follow GNU style packing.
1130 Fix bug with missing initialization of member in init_diagnostics.
1131 This bug affects threaded version of GFS server.
1133 --- 2.0.18 2004/03/20
1135 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1138 Ensure zlib.dll is packed with Windows install.
1140 --- 2.0.17 2004/03/17
1142 Fix encoding of xsd:string to use text instead of CDATA.
1144 Fix endless loop in CQL parser with unbalanced ".
1146 Use a more compact way to store MARC-8 conversion tables.
1148 --- 2.0.16 2004/03/16 Debian only
1150 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1153 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1158 --- 2.0.15 2004/03/01
1160 Another fix for decoding of XML packed records.
1162 --- 2.0.14 2004/02/25
1164 Fixes for Chunked encoding. White space not ignored after length spec.
1166 Update NS and use default NS for SRW diagnostic elements.
1168 --- 2.0.13 2004/02/23
1170 Implement ZOOM_resultset_cache_reset which resets record cache.
1172 Implement ZOOM_resultset_sort which sorts a result set.
1174 Implement chunked HTTP transfer.
1176 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1178 --- 2.0.12 2004/02/16
1180 Added member 'schema' to bend_explain_rr structure so that backend
1181 can specify explain record identifier. Defaults to Zeerex 2.0.
1183 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1185 --- 2.0.11 2004/02/16
1187 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1190 Added init command for yaz-client which sends "extra" init request.
1192 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1193 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1195 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1197 Make ZOOM error code for "invalid query".
1199 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1201 --- 2.0.10 2004/02/05
1203 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1206 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1208 Added option -p <file> to make Generic Frontend Server to write PID file.
1210 Added option -D to put Generic Frontend Server in background on its own.
1212 Make ZOOM C recognize option "password". If unset, "pass" is used
1213 (for backwards compatibility).
1215 Fixed a bug in Generic Frontend Server that could make it crash if a
1216 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1219 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1220 Must be issued before open, in order to be in effect.
1222 --- 2.0.9-6 2004/01/12 Debian/Windows
1224 Make the SRU server more picky WRT unknown params, etc.
1226 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1228 New YAZ client command, options, that sets Z39.50 options.
1230 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1231 options from a string of tokens (one token for each option bit).
1233 Update SRW diagnostic code messages.
1235 --- 2.0.9-5 2004/01/07 Debian/Windows
1237 Handle user defined stylesheet for SRW/SRU.
1239 --- 2.0.9-4 2004/01/06 Debian/Windows
1241 Fix bug in decoding of Content-Length.
1243 --- 2.0.9-3 2004/01/06 Debian/Windows
1245 Fix a bug with decoding of XML packed records.
1247 --- 2.0.9-2 2004/01/05 Debian only
1249 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1251 Fix bug in SRW/SRU diagnostics decoding.
1253 --- 2.0.9 2004/01/05
1255 Fixed bug in Generic Frontend Server which could drop records exceeding
1256 preferred message size. Reported and fixed by Irina Dijour.
1258 Fixed calculation of package size for structured records in Generic
1259 Frontend Server. Reported and fixed by Irina Dijour.
1261 Fixed namespace for SRW/SRU diagnostics.
1263 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1265 --- 2.0.8 2003/12/22
1267 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1268 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1271 CQL changes to reflect recent changes to the specification:
1272 * Documentation talks about context sets instead of index sets.
1273 * Documentation talks about indexes instead of qualifiers.
1274 * The CQL-to-PQF transformer's configuration file now uses
1275 "index.set.name = <attributes>" instead of the old form
1276 "qualifier.set.name = <attributes>". (Both forms are still
1277 understood but the latter is deprecated.)
1278 * CQL terms with no explicit index specified are now interpreted as
1279 cql.serverChoice instead of srw.serverChoice (which of course
1280 behaves exactly the same.)
1282 --- 2.0.7 2003/12/16
1284 MARC conversion can now generate ISO2709 output in another
1285 character set. yaz-marcdump uses this facility if you invoke it
1288 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1289 functions from there can be used from C++.
1291 --- 2.0.6 2003/12/04
1293 Frontend server now transfers memory from decoded packages to stream
1296 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1297 references to show up.
1299 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1300 the ZOOM Abstract API. The older names for the same options are still
1301 also supported for the benefit of old applications.
1303 ZOOM-C supports "implementationId" and "implementationVersion" options
1304 to go along with "implementationName". These allow the user code to
1305 specify identification strings to be sent to servers.
1306 Add OID for the new ExtLite attribute set.
1308 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1309 as requested/supplid by Ere Maijala <ere@atp.fi>
1311 For generic frontend server, reverse the order of
1312 "toolkit-supplied / application-supplied" strings sent as implementationId,
1313 Name and Version. Also, remove the spaces around the slash. This brings
1314 the GFS in line with the behaviour of ZOOM-C on the client side.
1316 Add function ZOOM_scanset_display_term.
1318 yaz-client shows scan displayTerm if present.
1320 Utility yaz-iconv is now installed by default along with the man page
1323 Extend configure check for OpenSSL to use pkg-config where available (such
1326 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1327 server to specify uid/gid/mask for socket using the format
1328 unix:[user=uid,][group=gid,][umask=mask,]file=path
1329 If file= is omitted the existing format is assumed, e.g.
1331 in which case the mask is 0666 (rw for everybody).
1333 Major restructure of YAZ source. All source in libyaz is in src directory.
1334 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1335 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1337 Added man page for utility yaz-marcdump (used to be called marcdump).
1338 yaz-marcdump is installed by 'make install'.
1340 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1341 of incoming package failed.
1343 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1345 Change prototype of odr_perror: add const to message string.
1347 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1349 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1350 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1351 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1352 DNS lookup. There should not be any compatibility problems with this
1353 assuming that blocking=1 or 0 is used.
1355 Fix bad reference in UNIX comstack in function cs_addrstr.
1357 Fix for compilation on AIX.
1359 The generic front-end server (server/seshigh.c) now supports returning
1360 Init diagnostics to the client in User-information-field, in
1361 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1364 --- 2.0.4 2003/09/04
1366 Allow any CQL relation (not just all,any,exact,scr).
1368 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1369 that features the same UI.
1371 Implemented command update0 in YAZ client which is equivalent to
1372 update but uses old of Ext Update ASN.1.
1374 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1375 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1376 Previously no OID was used for this info.
1378 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1379 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1380 returns 'malformed search term' otherwise.
1382 SortResponse member resultCount now set to NULL in sort handler of
1385 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1388 Add three new utility functions for translating OIDs between various
1389 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1390 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1391 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1392 char *oid_to_dotstring(const int *oid, char *oidbuf);
1393 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1395 Reverted modifications for ES Update definition for z_IU0Update
1396 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1397 is back to YAZ 2.0.2.
1399 String value attributes for CCL parser.
1401 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1402 which their FirstSearch server returns in Init responses, sometimes
1403 carrying useful diagnostic information when Init fails. This has the
1404 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1405 "z39.50/oclcui.asn", where its definition is somewhat different from
1406 what OCLC document on their web-site, as required to interoperate with
1409 Support for anonymous authentication in yaz-client. Use the command
1412 * Fix the OID of the Index Data-local "admin" Extended Service from
1413 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1414 the 1000, which indicates a locally-defined OID, was a mistake.
1416 --- 2.0.3 2003/06/20
1418 Fix CCL directive @case handling so that it affects string match for
1419 both CCL keywords and qualifiers.
1421 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1422 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1423 Decoder has been updated with ASN.1 changes as listed in
1424 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1425 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1426 z_IUUpdate, remains unchanged.
1428 ZOOM_record_get may now return a record in a specific character set.
1429 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1430 "from" is the character set of record as returned by target. "to" is
1431 the character set to be returned. If omitted, "to" is UTF-8.
1433 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1435 New ODR utility, odr_getelement, which returns name of element for
1436 which encoding/decoding failed.
1438 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1439 in cases where a required element was omitted.
1441 Bug fix: some MARC8 sequences were not converted.
1443 New ZOOM option "step" which specifies number of records to be
1444 retrieved in one chunk. Used in conjunction with "start" and "count".
1446 SRW support for yaz-client. Use scheme http: to use it, e.g.
1449 yaz-client no longer does (un)intelligent character set conversions
1450 by default. Can be enabled with charset and marc_charset commands.
1452 xmalloc trace fix for 64-bit systems such as DEC alpha.
1454 Solaris 2.6 compile fix.
1456 New function, cql_strerror() translates SRW error codes, as returned
1457 by cql_transform_error(), into human-readable English strings. Used
1458 in yaz-client diagnostics when appropriate.
1460 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1461 converts it into a type-1 query which is sent to the server. This
1462 makes CQL available for use with all Z-servers, as opposed to the tiny
1463 minority that can handle CQL queries themselves.
1465 --- 2.0.2 2003/04/28
1467 New Debian package layout similar to the Redhat Package layout.
1469 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1470 and search result respectively.
1472 --- 2.0.1 2003/04/25
1474 Redhat package is now several packages: libyaz (runtime libraries),
1475 libyaz-devel (development and documentation, and yaz (utility programs).
1476 Package spec file by Morten Bogeskov.
1478 New member 'schema' in struct bend_fetch_rr which the name of requested
1479 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1480 handler MAY set this to reflect the schema of the returned record.
1482 New member 'display_term' in struct scan_entry. GFS now sets member entries
1483 and allocates scan entries to be filled by user scan handler. In previous
1484 version, entries member was allocated by the scan handler. That still works,
1485 but the GFS will ignore member display_term - assuming it was NOT set by
1486 the handler. The fact that the GFS now allocates the entries both allows
1487 for new members and makes a scan handler easier to write.
1489 Fix CQL lex buffer overflow.
1491 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1492 SRU default recordPacking is string.
1494 SRU protocol support for frontend server.
1496 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1498 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1500 Added scan for the ZOOM shell (zoomsh).
1504 * String Identifers for Schemas (Amendment 5).
1505 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1506 Old definition for schema
1507 Odr_oid *schema; /* OPT */
1512 Z_InternationalString *uri;
1513 #define Z_Schema_oid 1
1514 #define Z_Schema_uri 2
1517 * resultCount parameter to Sort Response (Amendment 1).
1518 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1520 Support for SRW 1.0 over HTTP. This is an optional feature and
1521 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1524 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1525 on the same port. SRW SearchRetrieveRequests are mapped
1526 to bend_init,bend_search,bend_fetch,bend_close.
1528 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1530 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1531 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1533 ZOOM connections are SRW based if schem http is used for hostname
1534 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1535 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1537 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1538 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1539 distance=n, order=true/false, relation=le, prox unit=word. If
1540 n is omitted, distance 1 is used.
1542 Fixed problem with C compiler include path in wrong order.
1544 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1545 on Solaris. Patch from Ko van der Sloot.
1547 New MARC decode API. All new functions operate on a yaz_marc_t
1548 handle. The most important new functions are: yaz_marc_create,
1549 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1550 decode and destroy respectively. Decoder can produce formats
1551 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1552 include/yaz/marcdisp.h.
1554 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1555 to UTF-8, UCS-32, wchar_t or Latin-1.
1557 * Prototypes for yaz_iconv_-functions moved to separate header
1558 include/yaz/yaz-iconv.h.
1560 Make a few private functions 'static' in unix.c. This prevents
1561 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1563 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1564 are set when Init Response is received.
1566 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1567 but returns diagnostic set as well.
1569 New function yaz_strerror which is a portable wrapper for
1570 strerror/strerror_r/GetLastMessage.
1572 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1573 is returned for MARC. If type is "oai", then OAI MARC is returned.
1575 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1578 --- 1.9.2 2002/11/26
1580 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1582 Fix bad race conditions on SIGTERM and terminate gracefully in
1585 Move retrieval (data1) module to Zebra since nobody seems to be
1588 Add GRS-1 render for ZOOM using same format as yaz-client.
1590 --- 1.9.1 2002/10/05
1592 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1594 Fix broken ESpec handling in data1 module.
1596 SGML reader parses comments and makes them part of the data1 tree.
1598 Added several type casts so that YAZ compiles as C++ code.
1600 ZOOM didn't handle PDU encoding failures properly.
1602 Added more Bib-1 diagnostics (approved extensions).
1604 GNU configure: better check for iconv.
1606 More portable use of accept, getpeername. Check for socklen_t. Use
1607 int/size_t if socklen_t is not defined.
1611 PQF parser rejects bad queries - including those with extra
1612 characters in them. PQF parser used to silently ignore that.
1613 Cleaner API for PQF added, which allows you to get detailed
1614 error information for bad queries (see yaz/pquery.h).
1616 Fixed bug in ZOOM_record_get for type "database".
1618 Implemented mini iconv library supporting conversions between
1619 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1621 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1623 --- 1.8.9 2002/08/20
1625 Fixed ZOOM C record cache so that preferredRecordSyntax and
1626 elementSetName is used to check for already fetched records.
1628 --- 1.8.8 2002/08/02
1630 Added three members in bend_initrequest structure to facilitate
1631 character set negotiation.
1633 Fixed a bug in frontend server that could cause indefinite
1634 loops under rare conditions.
1636 Revised character set utilities (charneg.h) so that encoding
1637 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1639 For PQF, directive @term <type> sets term type for Scan/Search.
1640 Here <type> is general, string, numeric, null. The term type
1641 is inherited - just like @attr.
1643 New call odr_set_charset that sets character set conversion for
1644 international-strings on a ODR stream. Prototype is:
1645 int odr_set_charset(ODR o, const char *to, const char *from);
1646 The InternationalString is still represented as C string in YAZ
1647 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1648 won't). On the protocol level, you can use any encoding.
1650 Support for UNIX sockets in ZOOM.
1652 Solaris recv sometimes returns errno == ENOENT. It is treated as
1653 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1655 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1656 both client and server. Code by Morten Bogeskov.
1658 --- 1.8.7 2002/05/22
1660 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1661 that they can be used directly from Visual Basic. You must recompile
1662 your windows APP if you're using ZOOM.
1664 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1665 Commands "lang" and "charset" sets language and character set respectively.
1666 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1667 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1669 Attributes from multiple CCL fields may be OR'ed rather than merged
1670 using directive "@field or". Fields are still merged by default -
1671 equivalent to "@field merge".
1673 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1676 Fixed bug in zget for parameter ExtendedServicesResponse.
1680 --- 1.8.6 2002/03/25
1682 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1684 Client displays USR.1:SearchResult-1 (hits per term).
1686 Additional Search Info for search in Generic Frontend Server.
1688 Fixed CCL parsing of "field=s".
1690 WIN32 installer - using the excellent NSIS software from nullsoft.
1692 Fixed CCL parsing of "field = - <number>".
1694 Added function yaz_marc_decode that decodes MARC for line mode
1695 display or XML (similar to that used by JZKit).
1697 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1698 Z39.50. But ISO/ILL was, however.
1700 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1701 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1703 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1704 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1706 --- 1.8.5 2002/02/03
1708 New YAZ client features: Command completion and new commands:
1709 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1710 Code provided by Jacob Poulsen.
1712 New call oid_trav, that visits all registered OIDs via callback.
1714 Function ZOOM_record_get now returns const char pointer rather than
1715 void pointer. It saves a lot of type casts.
1717 For YAZ client, command "auth" now allows you to set authentication
1718 in IdPass style. It is enabled when three tokens are given - order
1719 is user, group and password.
1721 Fix memory leaks in MARC record handling for ZOOM.
1723 New option for YAZ client, -k <kilobytes> that sets
1724 maximum record size. Similar to -k option for generic frontend
1725 server and yaz-ztest.
1727 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1729 Prefix query parser reports "fail" when bad attribute set is given.
1731 Fix in MARC decoder. Proximity logging. Fix for attribute set
1732 in scan handler for server. Patches by Shigeru Ishida.
1734 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1737 Configure option --with-openssl=<dir> now works when a directory is
1738 specified. Patch provided by Morten Bogeskov.
1740 New option for YAZ client, -u <auth>, that sets authentication.
1742 ZOOM fix: error information was sometimes "missing", since error
1743 was cleared/reset too when it shouldn't.
1745 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1747 --- 1.8.4 2002/01/04
1749 Scan for ZOOM API. New object ZOOM_scanset. New functions
1750 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1751 ZOOM_scanset_destroy.
1753 New ZOOM function, ZOOM_connection_last_event, that returns type
1754 of last event (such as "receive data", "send data", "apdu received",
1757 New ZOOM option, schema, that specifies schema for retrieval.
1759 New CCL feature. Qualifiers can be aliases for one or more
1760 other qualifiers (if more than one is given, OR is used).
1762 ZOOM uses named result sets if target supports it.
1764 Two new YAZ client commands: . (dot, which sources a script of YAZ
1765 client commands), and ! (to execute shell command.). Implemented
1768 Working on Debian packages.
1770 --- 1.8.3 2001/11/19
1772 YAZ client enables named result sets only if target supports it.
1774 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1776 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1777 with key="host" to get same result.
1779 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1780 Function Z3950_resultset_record(s) returns references to records
1781 "owned" by resultset. To become owner use Z3950_record_clone.
1783 Function z_ext_record handles Extended Services. Thanks to
1786 --- 1.8.2 2001/11/12
1788 CCL Parser fix: ignore token comma when dealing with and-lists.
1790 Documentation updates for COMSTACK.
1792 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1793 Changed prototype Z3950_records. For some functions, int parameters
1794 were changed to size_t.
1796 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1799 New MARC decode/display function, marc_display_exl, which properly rejects
1800 non-ISO2709 records. YAZ client uses it.
1802 --- 1.8.1 2001/10/29
1804 Fix bug: local attribute set wasn't set correctly in PQF strings.
1808 * Old Z39.50 codecs no longer supported.
1810 Added ZOOM C binding. See http://zoom.z3950.org/
1812 Renamed states for COMSTACKs to avoid confusion with events.
1814 Implemented cs_look and proper cs_rcvconnect.
1816 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1818 Configure detects POSIX threads on OpenBSD.
1820 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1821 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1823 When error is returned from present handler, non-surrogate diagnostic
1824 is returned in present response (and fetch handler is no longer called).
1826 * Minor adjustments to pquery parser (PQF). Token characters may be
1827 escaped by using backslash (C-style).
1829 PQF parser allows string attribute values to be specified. For @attr,
1830 non-numeric characters after the equal-sign are treated as strings
1831 (e.g. @attr 9=title).
1833 CCL trunction character may be defined (@truncation in file)
1835 * function zget_ExtendedServicesRequest sets waitAction to
1836 waitIfPossible (was wait).
1838 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1841 CCL operator names may be set in field definition files (CCL_bibset).
1842 See ccl/bib1 for an example.
1844 Fixes in ASN.1 compiler for C++ compatibility.
1846 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1847 and "op_or" to avoid conflict with C++.
1849 Fixed problem with GNU readline detection on Redhat 7.0.
1851 Added step-size for Scan backend handler.
1853 Fixed bug that made the frontend server crash when no attribute
1854 set was specified for scan.
1856 Front-end server automatically switches to original working directory
1857 when installed as an NT service. Previously -w had to be specified to
1860 Added extended attributes for retrieval module (data1), so that data1
1861 records carry d1_readXML/SGML attributes. d1_read also supports
1862 null-data rules ( <tag/>)
1864 On UNIX when POSIX threads are available, a separate library libyazthread
1865 is created. Programmers should link with that library and the yaz library
1866 when using threads. The reason for the split was that some applications
1867 on Linux, such as Apache, doesn't work well when using shared objects that
1870 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1871 (or any frontend server) in SSL mode by specifying ssl: followed by
1872 address. Only tested on UNIX.
1874 Added feature for CCL module. Virtual structure s=al or s=ol generates
1875 and-list and or-list respectively instead of phrase search.
1879 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1880 log_mask_str. This was done to avoid name conflicts with other libraries
1881 (such as other PHP extensions).
1883 Added raw OID member for preferred record syntax (request_format_raw)
1884 and returned record syntax (output_format_raw) for backend fetch method.
1886 Config file yaz-config now accepts options so that it returns specific
1887 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1889 Shared library support for UNIX using GNU libtool.
1891 * Modified backend interface. Request/Response struct's replaced by
1892 one read/write C struct. For example bend_fetchrequest and
1893 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1894 Every handler - even search has to be registered in bend_init
1895 handler. This means that the YAZ library no longer refers to
1896 external functions and it makes it possible to make the whole
1897 thing a single DLL/SO.
1899 Added Segment handler for backend server.
1901 Added Zmbol/Zebra administrative functions to YAZ client.
1903 Threaded frontend server on UNIX (when POSIX Threads are available).
1904 Starting the server with option -T enables multi-threading.
1908 Added configure option --enable-comp/disable-comp to control use
1909 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1910 located in sub directory asn.
1912 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1913 in ${exec_prefix}/bin along with the other programs yaz-client and
1916 GNU automake used to maintain makefiles.
1918 Added several OID's.
1920 Changed retrieval module so that we can load records with no abstract
1921 syntax defined. Tagpaths in these records are fully composed of string
1924 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1928 On UNIX, the generated makefile now supports a proper 'make install'.
1929 The prefix can be set via GNU configure to set the install location
1930 (default is /usr/local).
1932 * YAZ programs client and ztest were renamed to yaz-client and
1933 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1934 locations, such as /usr/bin,/usr/local/bin,etc.
1936 * YAZ Header files were moved from include to include/yaz. YAZ Header
1937 files are referred to as include <yaz/log.h> rather than <log.h>.
1938 The YAZ include path (-I ..) is therefore the same as before. Programmers
1939 should update their #include statements or use -Ipath/include/yaz
1940 instead. The main motivation for doing this change is that YAZ header files
1941 can be installed in "standard" locations /usr/include,/usr/local/include
1942 without introducing conflicts, since ALL YAZ header files are stored
1943 in subdirectory yaz (under /usr/include for example).
1945 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1946 rather than project/workspace files. We switched because project files
1947 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1950 Changed name of logging function, logf, to yaz_log, to prevent name
1951 clash with some math-log functions. The YAZ header log.h defines logf
1952 to yaz_log (#define) so there should be no incompatibilities by this
1955 Added bend_start/bend_stop handlers for server. These handler are
1956 called on start/stop of server. For windows they are called whenever
1957 a service is started/stopped.
1959 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1960 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1961 in util/yc.tcl. The auto-generated C code structures are, in a few
1962 cases, incompatible with the old decoders. There are differences in the
1963 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1964 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1965 The preprocessor variable ASN_COMPILED is defined when the compiled
1966 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1967 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1968 wish to use the old encoders/decoders you can specify --disable-yc
1971 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1972 version so that it supports both new - and old version of DB Update
1974 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1975 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1976 change. The name parameter can be set to 0 in which no name is specified
1977 for the construction. The macros odr_implicit and odr_explicit sets name
1978 parameter to zero for the construction involved. New macros
1979 odr_implicit_tag and odr_explicit_tag are similar to the others,
1980 except that a name parameter is added. For programmers' that don't use
1981 ODR they probably only need to change the call to z_APDU and z_External.
1983 Added access control facility by interfacing the TCP wrapper library.
1984 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1985 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1986 name of the daemon and enables the access control as specified in
1987 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1989 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1990 den Dool <H.M.vdnDool@kub.nl>.
1992 Added reference ID parameter to most functions in server API - refer
1993 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1995 Changed name of ccl library to libccl.a (was ccl.a).
1997 Fixed bug in decoder for Explain (Category TargetInfo).
1999 Added support for GNU readline in client. Thanks to Jacob Poulsen
2000 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2002 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2003 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2004 IMPLEMENTATION! This change was made to the development version before
2005 the ZIG decided to retract the amendment. If any users MUST be
2006 compatible with the original Update definition, PLEASE CONTACT US, and
2007 we will include a separate definition corresponding to the old Update
2008 ES. Note that because of the change to the ASN.1 of the
2009 TaskPackageRecordStructure we cannot define a single structure that
2010 will support both versions.
2012 * Added const modifier to buffer parameter for some ODR/BER encoding
2013 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2014 completeWAIS, odr_dumpBER.
2016 Fixed bug in client.c which caused a crash when a scanResponse didn't
2017 contain positionOfTerm.
2019 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2020 * will cause an error in a client if a non-YAZ target sends both a
2021 * list of Scan entries and non-surrogate diagnostics.
2023 Retrieval module enhancements. Tag sets may be typed in the reference
2024 to it. From the .abs-file the "tagset" directive takes a third optional
2025 integer type for the tag set referenced. From a .tag-file the "include"
2026 directive takes a third optional type as well. The old "type" directive
2027 in the tag set itself is still recognized but acts as the default type
2030 Backend interface change. Individual Scan terms returned from bend_scan
2031 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2032 in include/backend.h.
2034 Retrieval module enhancements. Multiple tag sets and attribute sets may
2035 be specified in abstract syntax specs. Revised the error/warning for
2036 logging messages reported by the retrieval module when reading the
2039 Object Identifier system (oid_..) changed. The API is backwards
2040 compatible but the oid-routines now allocates new OID's when needed.
2041 Raw OID's may be specified in oid_getvalbyname.
2043 YAZ now uses GNU configure to generate Makefile(s).
2045 * Minor changes in some of the member names of DeleteResultSetRequest and
2046 DeleteResultSetResponse. See include/proto.h.
2048 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2049 and added member 'languages' in TargetInfo (which was missing).
2051 Changed the way attribute sets are handled in the retrieval
2052 module. These are now cached, just like the abstract syntaxes
2055 Changed YAZ so that it links with compiled ASN.1.
2057 Added Explain-schema definitions and mapping routines. The following
2058 Explain categories have been implemented: AttributeDetails,
2059 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2061 Fixed minor bug in Windows version of Server Library.
2063 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2065 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2067 Added EXTERNAL: UNIverse Resource Report (non-standard).
2069 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2070 ENUMERATED and SET OF.
2072 * Added 'const' to some of the char pointer arguments for the
2073 functions, data1_read_node, data1_getelementbytagname,
2074 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2077 Fixed bug in data1_insert_taggeddata - the last_child member of
2078 parent wasn't initialised.
2080 * Changed data1_read_record and data1_read_node so that the supplied
2081 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2082 doesn't refer to any parts of the "SGML"-buffer.
2084 Fixed bug in server library (Windows version of statserv_remove).
2086 * Changed code so that it compiles as C++. The type definition
2087 of Odr_fun which is a member of Odr_arm was changed. The result is,
2088 that an explicit typecast is needed for the fun pointer when
2089 using Odr_arm - as in:
2090 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2092 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2094 Implemented the new structured date and time definition as approved
2095 by the ZIG. Added schemaId element to the specificTag in Espec-1
2096 (also approved at the last ZIG). Thanks to RVDM.
2098 Added some Object identifiers (RVDM).
2100 Changed the Update Extended Service (RVDM).
2102 Added command "refid" to client which specifies referenceId for
2103 the following requests.
2105 Implemented extended service handling for server. See ztest.c
2106 for an example as well as backend.h. New handlers are registerd
2107 in the Init handler.
2109 * Changed interface for sort in server.
2111 Added new members to statserv_options_block. It allows a server
2112 to read options from another source than just the command line. Thanks
2113 to Charles Woodfield.
2115 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2116 renamed to zboolean. Some C++ compilers complained about the name.
2118 Minor changes to gils.abs. Added index 's' (sort) on title
2119 and date/time-last-modified.
2121 --- 1.4pl2 1998/1/30
2123 Fixed bug in server library regarding inetd mode (-i). This bug
2124 was introduced by release 1.4.
2126 --- 1.4pl1 1998/1/29
2128 Added sort facility in client and backend server interface.
2130 Fixed problem with dependencies in Makefile(s).
2132 Fixed bugs for encoders/decoders of extended services and
2135 Implemented sub-tree feature for schemas. Sub-trees are
2136 referenced in *.abs-files. See explain.abs for an example
2137 of the use of this feature.
2139 Modified bib1.att; local attributes for ANY didn't include
2140 ANY itself (only affects use of the retrieval module).
2142 Fixed bug in plain SGML reader in function data1_read_node:
2143 tags with prefix "var" was incorrectly interpreted as variants.
2145 Added feature "sub-schemas" to enable references to - and definitions
2146 of - group of elements.
2148 * Removed member parent from type data1_element (in data1.h).
2150 Implemented function odr_nullval() that returns the value of
2153 * Removed member num_children from data1_node (in data1.h).
2155 Made NT service interface part of the server library. The
2156 function statserv_main uses the NT service when required and
2157 calls the statserv_start / statserv_close routines.
2159 Routine zget_SearchRequest and zget_PresentRequest fills
2160 resultSetName/Id member with "default" instead of "Default".
2162 Fixed memory leak in server. Request queue member wasn't freed.
2164 Fixed nmem_exit so that memory is freed.
2168 Revised the CCL parser utility to be thread safe.
2170 Added function, oid_ent_to_oid, to replace the function
2171 oid_getoidbyent, which is not thread safe.
2173 * Added nmem_init and nmem_exit to initialize and release
2174 NMEM resources. Function nmem_init should be called once in the
2175 initial thread before NMEM/ODR is used. statserv.c and client.c
2176 have been changed accordingly. The change was necessary to make
2177 NMEM thread safe. The NMEM memory pool is shared amongst threads
2178 in a process. Unix-based applications will still work fine without
2181 Added NT Services interface for the the Z39.50 (statserv) Server.
2182 Refer to the ztest.c source on the usage.
2184 Windows 95/NT port using MSVC5.0. Project files are included in the
2187 * Defined new 'global' handle for the retrieval (data1) system. The
2188 new handled, data1_handle, describes the state of the data1 system.
2189 This handle is passed as first argument to virtually all
2190 data1 related routines. The functions data1_create and data1_destroy
2191 creates and destroys a data1 handle respectively.
2193 Added ODR encode stream member to all backend request structures
2194 init, search, scan etc. This stream should be used to allocate all
2195 memory used for the response when thread safe operation is needed.
2197 Changed the comstack utility, cs_addstr, to be thread safe. The
2198 returned hostname string returned by the function is now part the
2201 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2202 function. The cs_straddr takes a COMSTACK handle as argument, so this
2203 function must be used after cs_create and before bind/connect.
2204 This function is thread safe.
2206 Moved test server to 'ztest' directory - generic server code still
2207 in 'server' directory.
2209 Made prefix query (pquery.c) utility thread safe.
2211 Added new function modifier YAZ_EXPORT to 'export' public DLL
2212 functions when using windows (see include/yconfig.h).
2214 Added definitions to the OID database (util/oid.c) (RVDM).
2216 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2218 Added call to ccl_rpn_delete in client program.
2220 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2221 release of RPN structure.
2223 Added support for C++, headers uses extern "C" for public definitions.
2224 With input from RVDM.
2226 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2227 Thanks to Ronald van der Meer (RVDM).
2229 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2231 Added support for private extensions to the OID database
2232 (oid_setprivateoids()). Thanks to RVDM.
2234 Added optional, physical ANY (key replication)
2236 Fixed null-reference problem in GRS-1 output filter.
2238 Proximity operator added to Prefix Query Format (PQF).
2240 In test client command "base" accepts multiple databases.
2242 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2246 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2248 Smallish bug-fixes in the new encoders/decoders (explain).
2250 Bug fixed in DeleteRequest.
2252 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2254 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2256 Added SOIF syntax (using private OID for now) to retrieval module and client.
2258 Added Update extended service.
2260 Added SearchResult-1 additional info structure.
2262 Added optional CCL (ISO8777) interpreter as separate module. Available
2265 --- 1.2 1996/6/10 (1st anniversary release)
2267 Added Summary record syntax. Lightly tested.
2269 Added OPAC record syntax. Untested.
2271 Added ResourceReport service encoders/decoders. Untested.
2273 Fixed bug in z_Unit - wrong tagging on unitSystem.
2275 Fixed bug in the DiagRecs decoder.
2277 Added options for max PDU size and session timeout to frontend-server.
2279 Added documentation of query-language parsers and other supporting utilities.
2281 [frontend-server] Added Attribute set to the bend_scanrequest API.
2283 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2284 surrogate diagnostics were generated.
2286 [retrieval] Allow multiple local values for attribute.
2288 [retrieval] Allow multiple attributes per element in .abs files. index type.
2290 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2292 --- 1.1pl2 1996/4/10
2294 Minor changes, mostly specific to Zebra's requirements (retrieval)
2298 Repaired bug in frontend server when running multiple listening
2299 endpoints in dynamic mode.
2301 z_External() now won't break if a known, ASN.1 value comes encapsulated
2302 in an octet-string. The value will pass through unmodified in an Odr_oct.
2304 Added a bit of code to the demo client to decode & display
2305 ASN.1-structured records represented in the octet-aligned branch of
2306 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2308 Added z_ext_getentbyref() to the ASN module. Doc updated.
2310 * Completed the SCAN definition in the ASN module. This may break SCAN
2311 code based on older YAZ-versions at compile-time. The fix is easy -
2314 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2315 under the SCAN definition. Remember to initialize this, server-people.
2317 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2318 that this does not extend to ODR and ASN.
2320 Comstack allows insertion of established socket (primarily for
2321 inetd-operation of servers). Doc updated.
2323 Front-end server can now start from the inetd in TCP mode. Doc
2326 --- 1.0pl4 1996/1/24
2330 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2331 the rank and record number.
2333 Adjustments to the frontend server.
2335 Fixed diagnostic BER dumper. It ignored the file argument.
2339 Various changes to retrieval module.
2341 Changed the union discriminators of the protocol files from enums to
2342 ints paired with #defines.
2344 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2347 *Changed operator in the RPN structure to 'roperator', again to avoid a
2350 Fixed problems in Explain decoders/encoders.
2352 --- 1.0pl2 1995/12/6
2354 Memory bug in log module fixed.
2356 --- 1.0pl1 1995/12/5
2358 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2360 Bug in Explain DatabaseInfo module fixed.
2362 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2366 The shift to v1.0 signals that we now consider the *core* functionality
2367 of YAZ reasonably stable (the core being more or less equivalent to
2368 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2369 tested (Explain not at all - though that will happen soonish).
2371 Minor changes to code to support Windows port.
2373 Various minor changes after we're getting to use GRS-1 & co. more.
2375 Added Espec-1 format.
2377 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2378 of the protocol and it cannot be selected when encoding (maps into 'string'
2379 when decoding). Needed to talk to some servers.
2381 Demo client can request simple element set names.
2383 Added Diagnostic Format encoders/decoders.
2385 Added simple Close handling to frontend server (no hooks for resource
2386 reporting yet), and demonstration client.
2388 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2390 --- 1.0b3 1995/08/24
2392 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2393 handled incorrectly when records were requested in the searchResponse. This
2394 will only affect you if you use the frontend-server.
2396 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2397 Test-client will ask for and print GRS1. Ztest will return dummy records
2400 Added Explain encoders/decoders to the service-level API. Untested.
2402 Added Extended Services: Item Order encoders and decoders to the Service-
2403 level API. Untested. We could use a recent copy of the pertinent bits
2404 of the ILL protocol to add those bits.
2406 Added diagnostic format 1 encoders/decoders to the service-level API.
2409 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2410 odr_cons.c, which causes a more correct output.
2412 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2413 was always set to 0 when no records were requested in the searchRequest.
2415 * Added better external-handling. This shouldn't harm old code that
2416 *encodes* externals. It can break code that looks for a
2417 'single-ASN1-type' representation, since those types that are known
2418 are now decoded immediately. Look at the SUTRS sample code in
2419 seshigh.c and client.c. Documentation updated.
2421 Handling of structured records in bend_fetchresponse. Length -1 marks
2422 structured record, type is deduced from format field.
2424 --- 1.0b2 1995/06/27
2425 Fairly quick maintenance release to add SUTRS support.
2427 Fixed handling of SUTRS records in the demonstration client.
2429 * Added format field to the bend_fetchrequest and bend_fetchresponce
2430 structures of the backend API (frontend server). When the record is
2431 returned, the value of the format field is mapped to an OID. The
2432 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2433 of the record. The special value VAL_NONE in the bend_request means
2434 that no specific format was requested by the client. Documentation
2435 updated accordingly. Test server (ztest) will return a fixed dummy
2436 SUTRS record if your client requests SUTRS.
2438 Documentation updated accordingly.
2440 You can now set external libraries and RANLIB support in the top-level
2444 First public release.
