3 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
7 Fixed memory violation that could occur when decoding UTF-8. This bug
8 was only present in 3.0.30 of YAZ.
12 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
13 GNU TLS is used by default (if found).
15 yaz-ztest returns OPAC records if a client asks for OPAC.
17 Improved speed of MARC-8 encoding.
19 Added support for lossy and loss-less MARC-8 encoding.
21 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
23 Added new Windows Service wrapper (sc).
25 yaz-client's itemorder command may now send a file.
27 Fixed yaz-marcdump to allow the use of NS prefix for record element.
29 Added new function yaz_log_xml_errors.
31 Allow (but warn) unknown XML attributes in MARCXML parsing.
33 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
35 The UTF-8 to MARC-8 conversion now uses a different set of characters
36 for Greek symbols. Bug #2120.
40 Added yaz_daemon (daemon.h).
42 Fixed bug #2068: pkg-config trouble
44 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
48 Document --with-xml2 option.
50 Added OPAC XML XSD (etc/opacxml.xsd).
52 Allow glob mask for name attribute in retrieval element for the
53 generic frontend server's retrieval facility.
55 Changed yaz_poll_poll to return yaz_poll_except for all returned events
56 except POLLIN/POLLOUT.
58 Fixed error handling in cs_listen. Bug #2037.
62 Fixed version in yaz/yaz-version.h.
64 Fixed bug #2027: Crash when closing connection.
66 Changed configure so that ICU support is only enabled if only ICU
67 and Libxml2 is available (because the ICU chain is XML based).
71 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
72 is built. Only this DLL depends on the ICU runtime.
74 yaz-ziffy is no longer part of YAZ. It is distributed separately by
75 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
77 Changed license of CCL module to 'Revised BSD'. After consultation with
78 remaining members of the original EUROPAGATE consortium, we are re-issuing
79 the CCL module without a separate license. The software was developed by
80 Index Data as part of a research project. The special license was included
81 to help feed usage information back to the project consortium to support
82 project evaluation. At this time, the project consortium has long-since
83 disbanded, and the majority of the original principals have retired. At the
84 same time, we have significantly modified the software during the following
85 years, to the point where very practically no original code remains. To
86 simplify re-use of the software, we have contacted those members of the
87 consortium who could be reached, and agreed to re-issue the module as a
88 proper part of the YAZ package.
90 Tcl scripts uses /usr/bin/tclsh as preferred shell.
92 CQL closer to being version 1.2 compliant. CQL also allows free-form
93 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
96 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
97 bug could make Extended services handling crash in the ZOOM layer. This
98 bug was only present in YAZ 3.0.18.
100 --- 3.0.18 2007/12/19
102 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
105 yaz-marcdump reads and writes collection wrapped records.
107 Handle OPAC for record conversion module.
109 Fixes for ICU wrapper.
111 Allow ICU libs to be controlled with --with-icu .
113 --- 3.0.16 2007/11/12
115 Added yaz_poll which is a wrapper for select/poll. When poll is available
116 and non-buggy, it is used, by yaz_poll . This allows more than 1024
117 sockets to be in use.
119 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
120 functionality through an XML based configuration (ICU chain). This system
121 is useful for search facilities such as Pazpar2 and Zebra that needs to
122 perform tokenization of indexed material. The ICU code in a separate
123 library libyaz3_icu.a.
125 Added HTTP tunnel facility for COMSTACK, bug #1752.
126 This is a facility that allows a Web proxy, such as squid, to tunnel
127 Z39.50 traffic. This facility is "transparent" to must applications
128 using YAZ. It's enabled by using pseudo transport connect: followed by
129 the proxy address, followed by command, then follwed by he regular
130 "virtual" addresss. For example,
131 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
133 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
135 --- 3.0.14 2007/09/21
137 Fixed bad memory reference in ZOOM_record - cuased by member not being
138 initialized. This was a problem only in YAZ 3.0.12.
140 Fixed bug in conversion from MARC to XML: Non-XML characters in control
141 fields were not removed.
143 Changed the way C code is generated from codetables.xml. Made a MARC-8
144 conversion trie for each characterSet section rather than codeTable.
145 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
146 of codetables.xml from Larry Dixson, LOC. Bug #1464.
148 --- 3.0.12 2007/09/12
150 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
151 from ZOOM_record_error).
153 ZOOM C function ZOOM_record_get returns record schema for type="schema".
155 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
157 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
159 Better SRW-to-Bib-1 diagnostic mapping.
161 ZOOM C and yaz-client announces SRU version 1.2 by default.
163 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
166 Fixed in yaz_sru_decode to allow other version than 1.1.
168 --- 3.0.10 2007/08/22
170 Added support for SRU scan for ZOOM.
172 Added support for the use of the older versions or Extended Service
173 Update in ZOOM. To faciliate this, an option "updateVersion" may be
174 set to the version , 1=first, 2=second, 3=third. The third version is
175 what ZOOM C has used so far. And that, obviously, is the default.
177 Added support for CCL queries in Z39.50 queries sent to the GFS (and
178 therefore in Zebra and in SimpleServer-based applications). The new
179 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
180 qualifier file used to transform incoming CCL queries into Type-1 RPN,
181 which is passed into the back-end search callback function.
183 Added support for HTTP Basic authentication in clients: the SRU/W
184 codec encodes the username/password elements of the PDU structure
185 appropriately, and these may be set using the "user" and "password"
186 options in ZOOM-C applications (the same options that are used for
187 Z39.50 authentication).
191 Fixed bug #1208: SSL appears to be broken in ZOOM.
193 Fixed bug #1206: Libxml2 include path weirdness.
195 Added oid_name_to_dotstring.
197 Allow elementSetName to be specified for ZOOM C record update.
199 Allow waitAction to be specified for ZOOM C based for Extended Services.
201 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
202 syntax OID. Bug introduced in YAZ 3 series.
204 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
208 Fixed bug #1157: yaz-client does not read .yazclientrc from current
209 directory. yaz-client now reads commands from file given by option -f
210 if specified; then tries to read .yazclientrc in current directory.
211 Failing that, it reads .yazclientrc from user's home directory.
213 Added support for correlationInfo Note and ID for Record Update via
216 Added yaz-client command querycharset which specifies character set for
217 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
218 (termListAndStartPoint).
220 Charset ISO5428:1984 is an alias for ISO5428-1984.
222 Implemented a way to perform scan in a result set using Z39.50. This
223 is achieved by attaching the result set name in the characterInfo
224 (type InternationalString) of OtherInformation in the Scan Request PDU.
225 The result set is identified in the otherinformation by the new OID:
226 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
227 This allows for scan in result set and faceted search . Zebra did some
228 of this in the APT term using attribute type 8 and value being result
229 set. Using the OtherInformation approach for this is cleaner and easier
230 to work with in proxies and the like. This facility can be used in
231 yaz-client using new command setscan which takes a result set as first
232 argument, start position (APT) as second.
234 Changed decoding of SRU XML packed records to deal with servers that
235 have recordData with XML data with multiple root nodes. Also make
236 comparison for recordPacking case insensitive. Again, one server
237 returns "XML" where others return "xml".
239 For SRU responses allow Content-Type application/xml as well as text/xml.
243 Fixed bug in character set conversion of BER strings. Bug introduced
248 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
250 For OID class, use oid_class consistently.
252 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
255 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
256 character set for bibliographic information interchange". By Giannis Kosmas.
258 Added documentation on new OID API.
262 Changes to generic frontend server interface: added new member
263 'query_charset' for bend_initrequest structure. A backend init handler
264 should set this member to its native character set for query terms.
265 When defined, the frontend server logic will announce this character set
266 to a client if the negotiationModel bit is set by the client. All server
267 implementors are encouraged to specify this. If a backend server does not
268 specify this a warning is issued using yaz_log(YLOG_WARN,..).
270 Added CCL utility to remove terms (stop words) from resulting RPN
271 tree. This is handled by functions with prefix ccl_stop_words_ .
273 New ZOOM C option, "rpnCharset", which allows client-side conversion of
274 terms in RPN queries.
276 Clean-up the CCL API. Moved some internal structures from ccl.h to
277 private header cclp.h. Changed ccl_parser_create so that a Bibset must
278 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
279 This is replaced by ccl_parser_find_str which takes a string instead.
281 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
282 libyaz.la is the core of YAZ except the generic frontend server and
283 does not depend on POSIX threads anymore. libyaz_server.la is the
284 generic frontend server facilities and uses POSIX thread functionality
285 if available. The libyaz.la no longer depends on POSIX threads because
286 the number of global structures is limited. NMEM no longer re-uses blocks
287 between threads ; it simply free's memory immediately but allocates in
288 "large" chunks as usual. We don't expect any performance penalties
289 because of this. The yaz_log system is still using a global log_level so
290 caution must be taken when modifying it with yaz_log_init_.. +
291 yaz_log_mask_str. This, however, should not cause any trouble because
292 these functions are called during initialization of application code
293 anyway. `yaz-config --libs server` returns libs for server applications;
294 `yaz-config --libs` returns libs for non-server applications.
296 New OID database - with public definitions in oid_db.h. Removed old OID
297 database including the head oid.h and definitions such as enum oid_value
298 and struct oident. The new OID database uses the same string names as
299 before but the 'protocol' is gone. There are now only two representations
300 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
301 converts from string to OID; functions with prefix yaz_oid_to_string
302 converts the other way.
304 Change to emit_term() in CQL-to-PQF query translation: when a term has
305 the /regexp relation modifier, do not process it for leading and
306 trailing "^" and "*", which have quite different meanings in regular
309 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
310 write handlers no longer carries a 'last' parameter. This will make
311 yaz_iconv flush "less" characters. A flush is performed by call to
312 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
314 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
315 removed, because function yaz_query_to_wrbuf does the same.
317 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
318 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
320 Deprecated MARC utility functions removed.
322 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
325 Branch split: YAZ_2_1_55_branch
327 --- 2.1.54 2007/03/16
329 Fix to ZOOM-C so that transparent reconnection is properly handled on
330 connections that are in asynchronous mode.
332 Fixed compilation on OpenBSD 4.0.
334 Large strings in GRS-1 records are now properly displayed in yaz-client.
336 Added character conversion support for "advancegreek"; based on patch from
339 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
340 sequence is met. Before the error was not set so it would be unknown.
342 Adjust yaz-marcdump MARC reader so that it skips until record separator
345 --- 2.1.52 2007/03/07
347 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
348 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
349 fd_set structure used as a bitmask for the FDs to be selected on.
351 Using ACX_PTHREAD macro to check for POSIX threads.
353 Fixed have-vsnprintf check.
355 --- 2.1.50 2007/02/23
357 Fixes for configure on BSD. Bug #900.
359 Added snprintf/vsnprintf wrappers for systems that don't have
360 limits (heavens forbid).
362 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
363 created before all previous tasks were completed and removed from the
364 task queue, the new task could be removed by a mistake.
366 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
368 Implemented pass-through CQL-to-PQF conversions. Bug #861.
370 Fixed bug #832: Problem with MARC/charset in yaz-client.
372 Fixed bug #668: save command line history for yaz-client.
374 Fixed bug #830: pkg-config support.
376 --- 2.1.48 2007/01/23
378 Extended ZOOM result set options with two options that may be read by
379 a client: resultSetStatus and presentStatus with values as specified for
381 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
383 Fixed bug #827: Using SSL fails on Debian etch.
385 Fixed bug #826: Weird looking chars for set of MARC records.
387 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
388 that is treated as an ItemOrder with itemRequest being an XML document
389 external. The value of "doc" is the content.
391 Extended the GFS search facility. New member of bend_search_rr
392 'estimated_hit_count' signals that hits is known to be an estmate
393 (higher or lower than real hit count). New member 'partial_resultset'
394 signals that the search was partial (hit count is lower or equal than
395 real hit count). For Z39.50, the information is stored in resultSetStatus
396 member of SearchResponse APDU. For SRU, the information is signalled
397 via SRU diagnostic 59: "Result set created with valid partial results
400 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
402 --- 2.1.46 2007/01/13
404 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
406 Added ZOOM_connection_peek_event.
408 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
409 the following new functions:
410 ZOOM_event_nonblock, ZOOM_connection_process,
411 ZOOM_connection_get_{socket,mask,timeout},
412 ZOOM_connection_fire_event_{timeout,socket}.
413 The existing blocking event handler, ZOOM_event, is a wrapper for the
414 + blocking ZOOM_event_sys_{poll,select}.
416 Implemented function ccl_xml_config which parses XML version of CCL
417 configuration (bug #798).
419 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
421 Added timings utility (yaz/timing.h)
423 --- 2.1.44 2007/01/03
425 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
428 Fixed bug #779: Rotation of apdu.log fails.
430 Fixed for character set conversions:
431 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
432 Honor G1 set in MARC-8 decoding.
434 --- 2.1.42 2006/12/17
436 Fixed bug #775: char conversion does not handle Alternative UTF-8
439 Implemented function yaz_marc_read_line which parses MARC line format
440 records. There is a wealth of formats out there. So far, this function
441 reads line records produced by yaz_marc_write_line.
443 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
444 more generic and easier to remember(!) options: -i format and -o format
445 which specifies input format and output format respectively - where
446 format is one of "marc", "marcxml", "line", "marcxchange".
448 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
449 does not print anything except warnings for records.
451 For yaz-marcdump, added support for MARC split into files (-s) with a given
454 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
455 spec, at http://www.loc.gov/standards/sru/record-update/
456 This has changed the binary layout of the following structs:
457 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
458 bend_update_rr . Patch by Ko van der Sloot.
460 Added GFS utility function bend_assoc_is_alive which returns 1 if
461 association is still alive (client is connected); 0 otherwise (client
462 closed connection). This allows busy servers to stop working for
465 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
466 been a separate piece of software. This version of ziffy has been modified
467 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
469 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
471 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
472 Client code may now interrogate options such as "init_opt_sort" to
473 find out whether the server claims to support various options.
475 --- 2.1.40 2006/11/27
477 Added utilities yaz_{set,get}_esn to set/get element set name from
480 Removed the build of libyazthread.la. The libyaz.so is the threaded version
481 of YAZ and has been so since YAZ 2.1.10.
483 Implemented ZOOM_record_error which returns error information for
484 record (surrogate diagnostic).
486 --- 2.1.38 2006/10/31
488 Updates for SRU Update by Ko van der Sloot:
489 1. Changed name from "operation" to "action"
490 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
491 versions in the code, marked as 'backward compatible'.
492 3. Added diagnostics for SRU Update.
494 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
496 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
498 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
500 For GFS, fixed problem with SRU diagnostic 'First record position out of
501 range' being issued for 0 hits.
503 zoomtst10 part of Windows Build.
505 --- 2.1.36 2006/10/13
507 Implemented yaz_filepath_comp which splits a path into file path
508 components (required by Zebra 2.0.3+).
510 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
511 BSD inspired license until now so this should not have any real impact on
512 anybody. See http://www.opensource.org/licenses/bsd-license.php
514 Fixed bug #687: Missing log lines.
516 Fixed bug #678: CQL to PQF translation does not preserve double-quote
519 Fixed bug #689: SRU diagnostics to be added.
521 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
522 whether a connection is idle (no more work do do).
524 --- 2.1.34 2006/10/04
526 Change type of optval from long to int for invocation of setsockopt with
527 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
529 Added support for specifying the max log file size for the Generic
530 Frontend Server. The size is given with option -r.
532 --- 2.1.32 2006/09/21
534 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
536 --- 2.1.30 2006/09/17
538 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
541 Fixed bug in Generic Frontend Server that could cause a server to stop
542 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
544 For the generic frontend server, the maximum record size is used as maximum
545 size of incoming packages (SRU + Z39.50). The value until was previously
546 only used in Z39.50 Init negotiation and, later, in a session controlled
547 sizes of records returned. This is controlled using -k option. It can be
548 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
550 --- 2.1.28 2006/09/04
552 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
555 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
557 New option for yaz-marcdump -lpos=value which allows setting a portion
558 of MARC header to a certain value.
560 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
562 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
563 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
565 --- 2.1.26 2006/08/15
567 Fixed problem with SRU mode type (soap, get, post) for yaz-client
570 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
572 --- 2.1.24 2006/08/08
574 Fixed MARC ISO2709 encoding routines to deal with character set
577 Minor changes to GFS logging. Database included in search request log
580 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
581 cached/multiple records.
583 Shared libraries are built by default on Unix+configure.
585 Changed cql2pqf transformation to use a different evaluation order. The
586 new order is: always, relation, structure, position, truncation, index
587 and relationModifier. Old order was: always, relation, relationModifier,
588 structure, index, position, truncation. Note that the the latter ones
589 override former ones for identical attributes.. The new scheme means that
590 it is possible to override any existing attribute with a relationModifier.
591 And also that it is possible to override everything for the index rule
592 (except the ones listed in relationModifier). No order is perfect but this
593 one, we believe, covers more real cases.. The "always" should have been
594 called "default", since the attributes there can be overridden with all
597 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
598 compilation phase, but also for yaz-config --cflags output. This allows
599 us to have public headers with Libxml2 stuff in them . It should also,
600 eventually, make Libxml2 checks redundant in packages using YAZ, such
603 --- 2.1.22 2006/06/15
605 Changed SRU update structure bend_update_rr so that SRU diagnostics are
606 stored in uri, message and details.. Previously diagnostics were stored
607 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
608 compatibility.. but he's probably the only one affected, so.
610 Added support for CCL, compiled on the client side, in ZOOM-C. This
611 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
612 input; the resulting query objects can be used for for searching with
613 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
615 YAZ' configure searches for OpenSSL by default.
617 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
618 SL_CTX_use_certificate_file. See
619 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
620 for more info. Thanks to Ko van der Sloot.
622 --- 2.1.20 2006/06/02
624 Bug #600: SRU GET, POST support for yaz-client. Introduced
625 command 'sru' which selects method SOAP/GET/POST.
627 Allow missingValueAction to be specified for the sortspec string -
628 function yaz_sort_spec. By default, the missing value action is null.
629 Use ! to specify "abort". Use = followed by stringvalue to specify default
632 Ensured that Present-handler (if defined) is called in GFS before any call to
633 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
634 searchRetrieve requests.
636 Documentation for YAZ is now based on the Docbook XML/XSLT using
637 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
638 is no longer depending on jade/openjade or docbook-to-man scripts.
639 PDF is no longer part of the distribution - but can optionally be
640 made using DSSSL/jadetex or FOP.
642 Added retrieval handling support in Generic Frontend Server to support
643 conversion between MARC/XML as well as XSLTtransforms. See
644 etc/yazgfs.xml for an example.
646 Added Authentication support to Generic Frontend Server in SRU
647 mode. Authentication using HTTP Basic is supported, as is the use
648 of 'x-username' and 'x-password' parameters in the request itself.
650 Added support for a new character set MARC8s identical to MARC8 except
651 that it converts combined characters to single Unicode characters in the
652 Latin-1 range (when possible).
654 --- 2.1.18 2006/04/24
656 ASN.1 compiler 0.4: generates brief Doxygen file header for
657 generated .h/.c files.
659 Utility yaz_iconv now supports conversion to MARC-8.
661 New facilities for the MARC module. The reading - and writing of
662 content are separate methods for the yaz_marc_t handle. The following
663 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
664 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
665 format). Write functions have prefix yaz_marc_write_.. The existing
666 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
667 available. Removed support for OAI-MARC and simplexml (not the
668 simplexml from PHP5).
670 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
671 to be returned for this connection.
673 --- 2.1.16 2006/03/31
675 Allow multiple languages and charsets to be specified with
676 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
677 negcharset iso-8859-1,utf-8
679 Translation of proximity nodes from CQL into PQF now works.
681 Moved to automake 1.8, 1.9.
683 Added function yaz_log_set_handler which allows a log handler to be
684 installed. This handler will be called for all log messages. Output
685 to file is also produced; but that can be disabled by passing NULL
686 fname to yaz_log_init_file.
688 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
690 For SRW (including GFS), accept application/soap+xml as content-type
693 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
694 produces NO stylesheet reference even if a default stylesheet is specified
697 --- 2.1.14 2006/03/14
699 Updated Windows package to include yazd.dll + yazd.lib for the
700 Development component.
702 If the environment variable YAZ_LOG is set, then it is used as a
703 string indicating the default level of logging to use if not
704 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
705 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
706 used as before. So, for example, to omit warnings from YAZ logging,
709 cql_transform() now map structure and other attributes before indexes,
710 so that index-specific structures and other attributes can override
711 defaults. So now a combination of mapping specifications such as:
713 index.dc.date = 1=date-modified 4=5
714 does the right thing.
716 cql_transform() now also respects the "always" mapping specification,
717 which establishes an initial set of attributes to be used for all
718 terms except where overridden by more specific attributes associated
719 with the index, relation or modifier.
721 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
722 which mode to use; one of "post", "get" or "soap" (SRW, default).
724 Fixes for yaz_iconv routines: changed trie-based character set conversions
725 to use only non-negative values for bit fields due to Sun's C compiler not
726 supporting negative values.
728 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
729 sequences where not read correctly. Fix by Rustam Usmanov.
731 Updated win/makefile to use options, settings which makes things
732 compile with VS C 2005.
734 --- 2.1.12 2006/02/01
736 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
738 In ZOOM socket code, use select instead of poll on MacOSX.
740 ZOOM-C now support client-side compilation of CQL into RPN that is
741 sent to the server, enabling CQL to be used against all Z39.50
742 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
743 ZOOM_query object, and submit it using ZOOM_connection_search().
744 The CQL-to-RPN translation uses a configuration file, the name of
745 which must be specified in the Connection's "cqlfile" option.
747 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
748 function, which takes as its start-term parameter a ZOOM_query object
749 (which may have had either CQL or RPN set into it).
752 --- 2.1.10 2005/11/29
754 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
755 GFS to support this as well. Backend handler, bend_srw_update, does the
756 update work. Code contributed by Ko van der Sloot.
758 Allow retrieval of Search Result-1 information in ZOOM by the use of
759 options that are attached to a result set. ZOOM documentation updated
762 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
763 UTF-8 conversion. Patch by Raj Patel.
765 Added option -m to GFS to control formatting of timestamps in log file.
767 Added 'exit' as synonym for 'quit' in yaz-client
769 Added support for specifying SRW resultSetId + resultSetIdleTime in a
770 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
771 for the new members. Patch by Ko van der Sloot.
773 Added support for SRU POST. It is supported for content-type
774 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
776 Do not build the separate Multi-threaded (MT) library libyazthread.la.
777 Instead make the library libyaz.la multi-threaded. Threading as a whole
778 can still be disabled by configure option --disable-threads. Previosly,
779 with older GLIBCs there were problems with MT libs under Apache. This
780 has now been fixed a long time ago.
782 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
785 CQL module modified to be case insensitive for relations/indexes/operations.
787 Fixed bug in CQL transform code: incorrect value relationModifieder
790 Added 'show all' command for yaz-client which retrieves all results
793 Added new yaz-client, xmles, which takes a (private) OID and
794 a document to be sent as an extended service request.
796 Describe new yaz-client commands wait_response and set_auto_wait.
798 Increase TCP/IP listener backlog from 3 (which I am guessing was
799 copied from the SunOS manual entry way back when) so SOMAXCONN, so
800 that the socket will queue as many incoming connections as it's able
801 to handle ongoing connections. In other words, it will never now
802 refuse a connection that it would be able to handle merely because
803 it's not got around to accepting() enough of the pending connections
804 yet. This is the behaviour anyway under Linux, where the listen()
805 argument is ignored; but not under BSD and on systems such as
806 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
807 YAZ-based servers should now be uniform across operating systems in
810 yaz-marcdump uses 64-bit file access on some systems. This is enabled
811 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
812 This allows yaz-marcdump to read large MARC batches (>2 GB).
814 Modified all YAZ source files - except the source which is auto-generated
815 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
818 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
819 corresponding to the existing *_setl() function. These allow option
820 values containing arbitrary valuues.
822 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
823 ZOOM_resultset_sort() in new applications. Its behaviour is identical
824 except that it returns an indicator of whether or not the sort
825 criterion was accepted (0 for OK, -1 for invalid).
829 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
830 MARC output rather than returning "new" buffer.
832 yaz-client warns about unknown init options.
834 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
838 Added support for SRW sort in Generic Frontend Server. Patch
839 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
840 sortKeys - or NULL if none is provided.
842 Fixed bug #307: It was impossible to specify indefinite/no timeout
843 for ZOOM_event. Special timeout value -1 now means indefinite timeout
846 Added support for multiple languages and charsets to be specified in
847 ZOOM. Each charset/language is separated by a blank. If negotiation is
848 in effect in init-response, Option
849 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
850 Code based on patch by Vasiliy Osadchuk.
852 Fixed bug #306: infinite recursion that occurred when calling
853 yaz_log_level_init as the first call (before other log level or
856 Fixed bug in scan handling in front end server: if preferred-Position-In-
857 Response was non-present, a NULL pointer referece was performed.
861 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
862 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
863 now defined for all those error codes. So instead of putting 109 in
864 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
865 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
867 Modified the yaz-marcdump utility to skip garbage bytes between MARC
870 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
872 Program yaz-client now exits and produces an error message if multiple
873 Z39.50 servers are specified on the command line (none or one allowed
876 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
881 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
883 Fixed bug #272: Preserve spacing for CCL terms.
887 Added support for virtual hosts and multiple backend servers for
888 the YAZ frontend server. The configution is XML based and
889 support specificition of CQL to RPN mappings and explain information.
890 See section "Virtual Hosts" in the YAZ manual.
892 Extended OPAC display utility. OPAC display utility renders
893 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
894 to supplement yaz_marc_decode_wrbuf.
896 Fixed a bug in MARC decoder that could caused it to crash for some
897 invalid MARC records. More diagnostics and warnings where added in
898 XML output (warnings, etc are stored in comments).
900 --- 2.0.34 2005/02/08
902 Fixes for UNIX domain sockets. Bug #261.
904 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
906 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
907 Added yaz_marc_subfield_str which defines subfield lead string which is
908 used in YAZ_MARC_LINE format. Default string is blank+$. Added
909 yaz_marc_endline_str which defines end of fields string used in
910 YAZ_MARC_LINE format. Default string is newline.
912 Experimental support for MarcXChange. This format can be produced
913 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
914 http://www.bs.dk/standards/MarcXchange.xsd
916 Added yaz-client commands scansize that sets maximum number of
917 entries to be returned by scan.
919 --- 2.0.32 2005/01/11
921 Added support for SRW scan in yaz-client and Generic Frontend Server.
923 * Added whereInList member to SRW Scan Term.
925 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
927 Fixed NMEM system to return aligned blocks on the smallest boundaries
928 that are suitably aligned for all possible types on the particular
929 architecture YAZ is being built for.
931 --- 2.0.30 2005/01/04
933 Fixed numerious warnings that was issued with newer versions of GCC.
935 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
936 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
939 Make YAZ Generic Frontend Server slightly faster.
941 Enhance (and reduce) logging for Generic Frontend Server.
943 Revert YAZ log system so that it flushes every write operation
944 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
946 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
947 instead of LOG_, due to name clash with syslog(3). LOG_ are still
948 present. New applications should define YAZ_USE_NEW_LOG=1 - this
949 will effectively disable old definitions.
951 --- 2.0.28 2004/11/09
953 Added yaz_log_time_format which specifies log format using
956 Added yaz_log_module_level which returns mask for a module. Value
957 is non-zero mask a if module is enabled; zero if disabled.
959 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
960 in include/yaz/cql.h.
962 Fixed bug #176: Dont throw diagnostics on empty SRU args.
964 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
966 Fixed bug #172: RPM builds does not enable SSL.
968 Doxyfile.in part of dist. Doxyfile generated by configure.
970 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
971 are given and the corresponding component does not exist.
973 Extend CCL documentation in YAZ reference. Describe r=r.
975 --- 2.0.26 2004/10/01
977 Fixed MARC->MARCXML conversion to properly deal with
978 fields, subfields, indicators having non-ASCII characters.
980 Fixed MARC->MARCXML conversion so that ASCII control characters
981 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
984 Added YAZ GFS support for conversion from Z39.50 surrogate
985 diagnostics to SRW surrogate diagnostics.
987 Bug fix: YAZ GFS did not return schema in explainResponse.
989 --- 2.0.25 2004/09/30
991 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
992 now converts recordSchema to elementSetName as well as schema URI.
994 Fixed bug in COMSTACK that prevented HTTP request packages from being
997 --- 2.0.24 2004/09/29
999 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1000 does not require white-space before and after the dash in a range, e.g.
1001 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1004 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1005 due to new GCC removing "redundant" code.
1007 Added yaz-client commands scanpos and scanstep that sets preferred
1008 position and step-size for scan.
1010 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1012 Added CCL utility ccl_qual_buf which parses one or more CCL
1013 spec lines in a buffer.
1015 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1016 of name and value - ignoring empty lines and comments.
1018 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1020 Added odr_get_element_path which returns current element path for an
1021 ODR handle. This utility is useful in error handling or user-defined
1024 Added ODR_PRINT utility odr_set_stream which is is a more generic
1025 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1026 to a write function and pointer to close function. The close function - if
1027 non-NULL - will be called during odr_destroy.
1029 Fixed bug in CCL parser where truncation char was not removed from
1030 right side when truncation=both was in effect.
1032 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1035 --- 2.0.23 2004/08/11
1037 Fix buffer overrun in CQL parser when dealing with proximity (%).
1039 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1040 to UTF-8/UCS conversion is now only based on codetables.xml.
1042 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1044 --- 2.0.22 2004/08/06
1046 Add support for more "commit changes" in ZOOM (uses Extended Services).
1048 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1051 Yet another small fix for configure of SSL.
1053 --- 2.0.21 2004/05/14
1055 Fix SSL libs for configure when --with-openssl=DIR is given.
1057 --- 2.0.20 2004/05/10
1059 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1061 SSL comstack now uses yaz.pem certificate file on server side
1062 by default. Certificate filename can be configured by calling
1063 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1065 Fix bug regarding multiple calls to ZOOM_connection_connect.
1067 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1069 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1070 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1072 ZOOM now allows inspection of X509 peer certificate for verification.
1073 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1075 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1076 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1077 as "modular" but it simplifies things.
1079 Added cs_get_peer_certificate to that returns peer X509 PEM.
1081 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1082 NULL if SSL is unavailable.
1084 Documentation about MARC decoding tools.
1086 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1088 --- 2.0.19 2004/03/30
1090 Rename CHANGELOG to NEWS to follow GNU style packing.
1092 Fix bug with missing initialization of member in init_diagnostics.
1093 This bug affects threaded version of GFS server.
1095 --- 2.0.18 2004/03/20
1097 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1100 Ensure zlib.dll is packed with Windows install.
1102 --- 2.0.17 2004/03/17
1104 Fix encoding of xsd:string to use text instead of CDATA.
1106 Fix endless loop in CQL parser with unbalanced ".
1108 Use a more compact way to store MARC-8 conversion tables.
1110 --- 2.0.16 2004/03/16 Debian only
1112 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1115 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1120 --- 2.0.15 2004/03/01
1122 Another fix for decoding of XML packed records.
1124 --- 2.0.14 2004/02/25
1126 Fixes for Chunked encoding. White space not ignored after length spec.
1128 Update NS and use default NS for SRW diagnostic elements.
1130 --- 2.0.13 2004/02/23
1132 Implement ZOOM_resultset_cache_reset which resets record cache.
1134 Implement ZOOM_resultset_sort which sorts a result set.
1136 Implement chunked HTTP transfer.
1138 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1140 --- 2.0.12 2004/02/16
1142 Added member 'schema' to bend_explain_rr structure so that backend
1143 can specify explain record identifier. Defaults to Zeerex 2.0.
1145 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1147 --- 2.0.11 2004/02/16
1149 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1152 Added init command for yaz-client which sends "extra" init request.
1154 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1155 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1157 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1159 Make ZOOM error code for "invalid query".
1161 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1163 --- 2.0.10 2004/02/05
1165 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1168 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1170 Added option -p <file> to make Generic Frontend Server to write PID file.
1172 Added option -D to put Generic Frontend Server in background on its own.
1174 Make ZOOM C recognize option "password". If unset, "pass" is used
1175 (for backwards compatibility).
1177 Fixed a bug in Generic Frontend Server that could make it crash if a
1178 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1181 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1182 Must be issued before open, in order to be in effect.
1184 --- 2.0.9-6 2004/01/12 Debian/Windows
1186 Make the SRU server more picky WRT unknown params, etc.
1188 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1190 New YAZ client command, options, that sets Z39.50 options.
1192 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1193 options from a string of tokens (one token for each option bit).
1195 Update SRW diagnostic code messages.
1197 --- 2.0.9-5 2004/01/07 Debian/Windows
1199 Handle user defined stylesheet for SRW/SRU.
1201 --- 2.0.9-4 2004/01/06 Debian/Windows
1203 Fix bug in decoding of Content-Length.
1205 --- 2.0.9-3 2004/01/06 Debian/Windows
1207 Fix a bug with decoding of XML packed records.
1209 --- 2.0.9-2 2004/01/05 Debian only
1211 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1213 Fix bug in SRW/SRU diagnostics decoding.
1215 --- 2.0.9 2004/01/05
1217 Fixed bug in Generic Frontend Server which could drop records exceeding
1218 preferred message size. Reported and fixed by Irina Dijour.
1220 Fixed calculation of package size for structured records in Generic
1221 Frontend Server. Reported and fixed by Irina Dijour.
1223 Fixed namespace for SRW/SRU diagnostics.
1225 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1227 --- 2.0.8 2003/12/22
1229 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1230 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1233 CQL changes to reflect recent changes to the specification:
1234 * Documentation talks about context sets instead of index sets.
1235 * Documentation talks about indexes instead of qualifiers.
1236 * The CQL-to-PQF transformer's configuration file now uses
1237 "index.set.name = <attributes>" instead of the old form
1238 "qualifier.set.name = <attributes>". (Both forms are still
1239 understood but the latter is deprecated.)
1240 * CQL terms with no explicit index specified are now interpreted as
1241 cql.serverChoice instead of srw.serverChoice (which of course
1242 behaves exactly the same.)
1244 --- 2.0.7 2003/12/16
1246 MARC conversion can now generate ISO2709 output in another
1247 character set. yaz-marcdump uses this facility if you invoke it
1250 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1251 functions from there can be used from C++.
1253 --- 2.0.6 2003/12/04
1255 Frontend server now transfers memory from decoded packages to stream
1258 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1259 references to show up.
1261 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1262 the ZOOM Abstract API. The older names for the same options are still
1263 also supported for the benefit of old applications.
1265 ZOOM-C supports "implementationId" and "implementationVersion" options
1266 to go along with "implementationName". These allow the user code to
1267 specify identification strings to be sent to servers.
1268 Add OID for the new ExtLite attribute set.
1270 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1271 as requested/supplid by Ere Maijala <ere@atp.fi>
1273 For generic frontend server, reverse the order of
1274 "toolkit-supplied / application-supplied" strings sent as implementationId,
1275 Name and Version. Also, remove the spaces around the slash. This brings
1276 the GFS in line with the behaviour of ZOOM-C on the client side.
1278 Add function ZOOM_scanset_display_term.
1280 yaz-client shows scan displayTerm if present.
1282 Utility yaz-iconv is now installed by default along with the man page
1285 Extend configure check for OpenSSL to use pkg-config where available (such
1288 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1289 server to specify uid/gid/mask for socket using the format
1290 unix:[user=uid,][group=gid,][umask=mask,]file=path
1291 If file= is omitted the existing format is assumed, e.g.
1293 in which case the mask is 0666 (rw for everybody).
1295 Major restructure of YAZ source. All source in libyaz is in src directory.
1296 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1297 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1299 Added man page for utility yaz-marcdump (used to be called marcdump).
1300 yaz-marcdump is installed by 'make install'.
1302 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1303 of incoming package failed.
1305 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1307 Change prototype of odr_perror: add const to message string.
1309 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1311 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1312 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1313 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1314 DNS lookup. There should not be any compatibility problems with this
1315 assuming that blocking=1 or 0 is used.
1317 Fix bad reference in UNIX comstack in function cs_addrstr.
1319 Fix for compilation on AIX.
1321 The generic front-end server (server/seshigh.c) now supports returning
1322 Init diagnostics to the client in User-information-field, in
1323 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1326 --- 2.0.4 2003/09/04
1328 Allow any CQL relation (not just all,any,exact,scr).
1330 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1331 that features the same UI.
1333 Implemented command update0 in YAZ client which is equivalent to
1334 update but uses old of Ext Update ASN.1.
1336 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1337 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1338 Previously no OID was used for this info.
1340 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1341 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1342 returns 'malformed search term' otherwise.
1344 SortResponse member resultCount now set to NULL in sort handler of
1347 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1350 Add three new utility functions for translating OIDs between various
1351 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1352 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1353 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1354 char *oid_to_dotstring(const int *oid, char *oidbuf);
1355 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1357 Reverted modifications for ES Update definition for z_IU0Update
1358 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1359 is back to YAZ 2.0.2.
1361 String value attributes for CCL parser.
1363 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1364 which their FirstSearch server returns in Init responses, sometimes
1365 carrying useful diagnostic information when Init fails. This has the
1366 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1367 "z39.50/oclcui.asn", where its definition is somewhat different from
1368 what OCLC document on their web-site, as required to interoperate with
1371 Support for anonymous authentication in yaz-client. Use the command
1374 * Fix the OID of the Index Data-local "admin" Extended Service from
1375 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1376 the 1000, which indicates a locally-defined OID, was a mistake.
1378 --- 2.0.3 2003/06/20
1380 Fix CCL directive @case handling so that it affects string match for
1381 both CCL keywords and qualifiers.
1383 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1384 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1385 Decoder has been updated with ASN.1 changes as listed in
1386 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1387 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1388 z_IUUpdate, remains unchanged.
1390 ZOOM_record_get may now return a record in a specific character set.
1391 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1392 "from" is the character set of record as returned by target. "to" is
1393 the character set to be returned. If omitted, "to" is UTF-8.
1395 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1397 New ODR utility, odr_getelement, which returns name of element for
1398 which encoding/decoding failed.
1400 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1401 in cases where a required element was omitted.
1403 Bug fix: some MARC8 sequences were not converted.
1405 New ZOOM option "step" which specifies number of records to be
1406 retrieved in one chunk. Used in conjunction with "start" and "count".
1408 SRW support for yaz-client. Use scheme http: to use it, e.g.
1411 yaz-client no longer does (un)intelligent character set conversions
1412 by default. Can be enabled with charset and marc_charset commands.
1414 xmalloc trace fix for 64-bit systems such as DEC alpha.
1416 Solaris 2.6 compile fix.
1418 New function, cql_strerror() translates SRW error codes, as returned
1419 by cql_transform_error(), into human-readable English strings. Used
1420 in yaz-client diagnostics when appropriate.
1422 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1423 converts it into a type-1 query which is sent to the server. This
1424 makes CQL available for use with all Z-servers, as opposed to the tiny
1425 minority that can handle CQL queries themselves.
1427 --- 2.0.2 2003/04/28
1429 New Debian package layout similar to the Redhat Package layout.
1431 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1432 and search result respectively.
1434 --- 2.0.1 2003/04/25
1436 Redhat package is now several packages: libyaz (runtime libraries),
1437 libyaz-devel (development and documentation, and yaz (utility programs).
1438 Package spec file by Morten Bogeskov.
1440 New member 'schema' in struct bend_fetch_rr which the name of requested
1441 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1442 handler MAY set this to reflect the schema of the returned record.
1444 New member 'display_term' in struct scan_entry. GFS now sets member entries
1445 and allocates scan entries to be filled by user scan handler. In previous
1446 version, entries member was allocated by the scan handler. That still works,
1447 but the GFS will ignore member display_term - assuming it was NOT set by
1448 the handler. The fact that the GFS now allocates the entries both allows
1449 for new members and makes a scan handler easier to write.
1451 Fix CQL lex buffer overflow.
1453 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1454 SRU default recordPacking is string.
1456 SRU protocol support for frontend server.
1458 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1460 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1462 Added scan for the ZOOM shell (zoomsh).
1466 * String Identifers for Schemas (Amendment 5).
1467 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1468 Old definition for schema
1469 Odr_oid *schema; /* OPT */
1474 Z_InternationalString *uri;
1475 #define Z_Schema_oid 1
1476 #define Z_Schema_uri 2
1479 * resultCount parameter to Sort Response (Amendment 1).
1480 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1482 Support for SRW 1.0 over HTTP. This is an optional feature and
1483 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1486 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1487 on the same port. SRW SearchRetrieveRequests are mapped
1488 to bend_init,bend_search,bend_fetch,bend_close.
1490 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1492 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1493 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1495 ZOOM connections are SRW based if schem http is used for hostname
1496 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1497 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1499 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1500 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1501 distance=n, order=true/false, relation=le, prox unit=word. If
1502 n is omitted, distance 1 is used.
1504 Fixed problem with C compiler include path in wrong order.
1506 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1507 on Solaris. Patch from Ko van der Sloot.
1509 New MARC decode API. All new functions operate on a yaz_marc_t
1510 handle. The most important new functions are: yaz_marc_create,
1511 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1512 decode and destroy respectively. Decoder can produce formats
1513 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1514 include/yaz/marcdisp.h.
1516 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1517 to UTF-8, UCS-32, wchar_t or Latin-1.
1519 * Prototypes for yaz_iconv_-functions moved to separate header
1520 include/yaz/yaz-iconv.h.
1522 Make a few private functions 'static' in unix.c. This prevents
1523 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1525 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1526 are set when Init Response is received.
1528 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1529 but returns diagnostic set as well.
1531 New function yaz_strerror which is a portable wrapper for
1532 strerror/strerror_r/GetLastMessage.
1534 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1535 is returned for MARC. If type is "oai", then OAI MARC is returned.
1537 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1540 --- 1.9.2 2002/11/26
1542 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1544 Fix bad race conditions on SIGTERM and terminate gracefully in
1547 Move retrieval (data1) module to Zebra since nobody seems to be
1550 Add GRS-1 render for ZOOM using same format as yaz-client.
1552 --- 1.9.1 2002/10/05
1554 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1556 Fix broken ESpec handling in data1 module.
1558 SGML reader parses comments and makes them part of the data1 tree.
1560 Added several type casts so that YAZ compiles as C++ code.
1562 ZOOM didn't handle PDU encoding failures properly.
1564 Added more Bib-1 diagnostics (approved extensions).
1566 GNU configure: better check for iconv.
1568 More portable use of accept, getpeername. Check for socklen_t. Use
1569 int/size_t if socklen_t is not defined.
1573 PQF parser rejects bad queries - including those with extra
1574 characters in them. PQF parser used to silently ignore that.
1575 Cleaner API for PQF added, which allows you to get detailed
1576 error information for bad queries (see yaz/pquery.h).
1578 Fixed bug in ZOOM_record_get for type "database".
1580 Implemented mini iconv library supporting conversions between
1581 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1583 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1585 --- 1.8.9 2002/08/20
1587 Fixed ZOOM C record cache so that preferredRecordSyntax and
1588 elementSetName is used to check for already fetched records.
1590 --- 1.8.8 2002/08/02
1592 Added three members in bend_initrequest structure to facilitate
1593 character set negotiation.
1595 Fixed a bug in frontend server that could cause indefinite
1596 loops under rare conditions.
1598 Revised character set utilities (charneg.h) so that encoding
1599 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1601 For PQF, directive @term <type> sets term type for Scan/Search.
1602 Here <type> is general, string, numeric, null. The term type
1603 is inherited - just like @attr.
1605 New call odr_set_charset that sets character set conversion for
1606 international-strings on a ODR stream. Prototype is:
1607 int odr_set_charset(ODR o, const char *to, const char *from);
1608 The InternationalString is still represented as C string in YAZ
1609 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1610 won't). On the protocol level, you can use any encoding.
1612 Support for UNIX sockets in ZOOM.
1614 Solaris recv sometimes returns errno == ENOENT. It is treated as
1615 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1617 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1618 both client and server. Code by Morten Bogeskov.
1620 --- 1.8.7 2002/05/22
1622 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1623 that they can be used directly from Visual Basic. You must recompile
1624 your windows APP if you're using ZOOM.
1626 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1627 Commands "lang" and "charset" sets language and character set respectively.
1628 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1629 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1631 Attributes from multiple CCL fields may be OR'ed rather than merged
1632 using directive "@field or". Fields are still merged by default -
1633 equivalent to "@field merge".
1635 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1638 Fixed bug in zget for parameter ExtendedServicesResponse.
1642 --- 1.8.6 2002/03/25
1644 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1646 Client displays USR.1:SearchResult-1 (hits per term).
1648 Additional Search Info for search in Generic Frontend Server.
1650 Fixed CCL parsing of "field=s".
1652 WIN32 installer - using the excellent NSIS software from nullsoft.
1654 Fixed CCL parsing of "field = - <number>".
1656 Added function yaz_marc_decode that decodes MARC for line mode
1657 display or XML (similar to that used by JZKit).
1659 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1660 Z39.50. But ISO/ILL was, however.
1662 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1663 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1665 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1666 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1668 --- 1.8.5 2002/02/03
1670 New YAZ client features: Command completion and new commands:
1671 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1672 Code provided by Jacob Poulsen.
1674 New call oid_trav, that visits all registered OIDs via callback.
1676 Function ZOOM_record_get now returns const char pointer rather than
1677 void pointer. It saves a lot of type casts.
1679 For YAZ client, command "auth" now allows you to set authentication
1680 in IdPass style. It is enabled when three tokens are given - order
1681 is user, group and password.
1683 Fix memory leaks in MARC record handling for ZOOM.
1685 New option for YAZ client, -k <kilobytes> that sets
1686 maximum record size. Similar to -k option for generic frontend
1687 server and yaz-ztest.
1689 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1691 Prefix query parser reports "fail" when bad attribute set is given.
1693 Fix in MARC decoder. Proximity logging. Fix for attribute set
1694 in scan handler for server. Patches by Shigeru Ishida.
1696 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1699 Configure option --with-openssl=<dir> now works when a directory is
1700 specified. Patch provided by Morten Bogeskov.
1702 New option for YAZ client, -u <auth>, that sets authentication.
1704 ZOOM fix: error information was sometimes "missing", since error
1705 was cleared/reset too when it shouldn't.
1707 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1709 --- 1.8.4 2002/01/04
1711 Scan for ZOOM API. New object ZOOM_scanset. New functions
1712 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1713 ZOOM_scanset_destroy.
1715 New ZOOM function, ZOOM_connection_last_event, that returns type
1716 of last event (such as "receive data", "send data", "apdu received",
1719 New ZOOM option, schema, that specifies schema for retrieval.
1721 New CCL feature. Qualifiers can be aliases for one or more
1722 other qualifiers (if more than one is given, OR is used).
1724 ZOOM uses named result sets if target supports it.
1726 Two new YAZ client commands: . (dot, which sources a script of YAZ
1727 client commands), and ! (to execute shell command.). Implemented
1730 Working on Debian packages.
1732 --- 1.8.3 2001/11/19
1734 YAZ client enables named result sets only if target supports it.
1736 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1738 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1739 with key="host" to get same result.
1741 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1742 Function Z3950_resultset_record(s) returns references to records
1743 "owned" by resultset. To become owner use Z3950_record_clone.
1745 Function z_ext_record handles Extended Services. Thanks to
1748 --- 1.8.2 2001/11/12
1750 CCL Parser fix: ignore token comma when dealing with and-lists.
1752 Documentation updates for COMSTACK.
1754 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1755 Changed prototype Z3950_records. For some functions, int parameters
1756 were changed to size_t.
1758 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1761 New MARC decode/display function, marc_display_exl, which properly rejects
1762 non-ISO2709 records. YAZ client uses it.
1764 --- 1.8.1 2001/10/29
1766 Fix bug: local attribute set wasn't set correctly in PQF strings.
1770 * Old Z39.50 codecs no longer supported.
1772 Added ZOOM C binding. See http://zoom.z3950.org/
1774 Renamed states for COMSTACKs to avoid confusion with events.
1776 Implemented cs_look and proper cs_rcvconnect.
1778 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1780 Configure detects POSIX threads on OpenBSD.
1782 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1783 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1785 When error is returned from present handler, non-surrogate diagnostic
1786 is returned in present response (and fetch handler is no longer called).
1788 * Minor adjustments to pquery parser (PQF). Token characters may be
1789 escaped by using backslash (C-style).
1791 PQF parser allows string attribute values to be specified. For @attr,
1792 non-numeric characters after the equal-sign are treated as strings
1793 (e.g. @attr 9=title).
1795 CCL trunction character may be defined (@truncation in file)
1797 * function zget_ExtendedServicesRequest sets waitAction to
1798 waitIfPossible (was wait).
1800 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1803 CCL operator names may be set in field definition files (CCL_bibset).
1804 See ccl/bib1 for an example.
1806 Fixes in ASN.1 compiler for C++ compatibility.
1808 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1809 and "op_or" to avoid conflict with C++.
1811 Fixed problem with GNU readline detection on Redhat 7.0.
1813 Added step-size for Scan backend handler.
1815 Fixed bug that made the frontend server crash when no attribute
1816 set was specified for scan.
1818 Front-end server automatically switches to original working directory
1819 when installed as an NT service. Previously -w had to be specified to
1822 Added extended attributes for retrieval module (data1), so that data1
1823 records carry d1_readXML/SGML attributes. d1_read also supports
1824 null-data rules ( <tag/>)
1826 On UNIX when POSIX threads are available, a separate library libyazthread
1827 is created. Programmers should link with that library and the yaz library
1828 when using threads. The reason for the split was that some applications
1829 on Linux, such as Apache, doesn't work well when using shared objects that
1832 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1833 (or any frontend server) in SSL mode by specifying ssl: followed by
1834 address. Only tested on UNIX.
1836 Added feature for CCL module. Virtual structure s=al or s=ol generates
1837 and-list and or-list respectively instead of phrase search.
1841 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1842 log_mask_str. This was done to avoid name conflicts with other libraries
1843 (such as other PHP extensions).
1845 Added raw OID member for preferred record syntax (request_format_raw)
1846 and returned record syntax (output_format_raw) for backend fetch method.
1848 Config file yaz-config now accepts options so that it returns specific
1849 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1851 Shared library support for UNIX using GNU libtool.
1853 * Modified backend interface. Request/Response struct's replaced by
1854 one read/write C struct. For example bend_fetchrequest and
1855 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1856 Every handler - even search has to be registered in bend_init
1857 handler. This means that the YAZ library no longer refers to
1858 external functions and it makes it possible to make the whole
1859 thing a single DLL/SO.
1861 Added Segment handler for backend server.
1863 Added Zmbol/Zebra administrative functions to YAZ client.
1865 Threaded frontend server on UNIX (when POSIX Threads are available).
1866 Starting the server with option -T enables multi-threading.
1870 Added configure option --enable-comp/disable-comp to control use
1871 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1872 located in sub directory asn.
1874 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1875 in ${exec_prefix}/bin along with the other programs yaz-client and
1878 GNU automake used to maintain makefiles.
1880 Added several OID's.
1882 Changed retrieval module so that we can load records with no abstract
1883 syntax defined. Tagpaths in these records are fully composed of string
1886 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1890 On UNIX, the generated makefile now supports a proper 'make install'.
1891 The prefix can be set via GNU configure to set the install location
1892 (default is /usr/local).
1894 * YAZ programs client and ztest were renamed to yaz-client and
1895 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1896 locations, such as /usr/bin,/usr/local/bin,etc.
1898 * YAZ Header files were moved from include to include/yaz. YAZ Header
1899 files are referred to as include <yaz/log.h> rather than <log.h>.
1900 The YAZ include path (-I ..) is therefore the same as before. Programmers
1901 should update their #include statements or use -Ipath/include/yaz
1902 instead. The main motivation for doing this change is that YAZ header files
1903 can be installed in "standard" locations /usr/include,/usr/local/include
1904 without introducing conflicts, since ALL YAZ header files are stored
1905 in subdirectory yaz (under /usr/include for example).
1907 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1908 rather than project/workspace files. We switched because project files
1909 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1912 Changed name of logging function, logf, to yaz_log, to prevent name
1913 clash with some math-log functions. The YAZ header log.h defines logf
1914 to yaz_log (#define) so there should be no incompatibilities by this
1917 Added bend_start/bend_stop handlers for server. These handler are
1918 called on start/stop of server. For windows they are called whenever
1919 a service is started/stopped.
1921 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1922 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1923 in util/yc.tcl. The auto-generated C code structures are, in a few
1924 cases, incompatible with the old decoders. There are differences in the
1925 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1926 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1927 The preprocessor variable ASN_COMPILED is defined when the compiled
1928 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1929 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1930 wish to use the old encoders/decoders you can specify --disable-yc
1933 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1934 version so that it supports both new - and old version of DB Update
1936 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1937 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1938 change. The name parameter can be set to 0 in which no name is specified
1939 for the construction. The macros odr_implicit and odr_explicit sets name
1940 parameter to zero for the construction involved. New macros
1941 odr_implicit_tag and odr_explicit_tag are similar to the others,
1942 except that a name parameter is added. For programmers' that don't use
1943 ODR they probably only need to change the call to z_APDU and z_External.
1945 Added access control facility by interfacing the TCP wrapper library.
1946 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1947 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1948 name of the daemon and enables the access control as specified in
1949 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1951 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1952 den Dool <H.M.vdnDool@kub.nl>.
1954 Added reference ID parameter to most functions in server API - refer
1955 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1957 Changed name of ccl library to libccl.a (was ccl.a).
1959 Fixed bug in decoder for Explain (Category TargetInfo).
1961 Added support for GNU readline in client. Thanks to Jacob Poulsen
1962 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1964 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1965 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1966 IMPLEMENTATION! This change was made to the development version before
1967 the ZIG decided to retract the amendment. If any users MUST be
1968 compatible with the original Update definition, PLEASE CONTACT US, and
1969 we will include a separate definition corresponding to the old Update
1970 ES. Note that because of the change to the ASN.1 of the
1971 TaskPackageRecordStructure we cannot define a single structure that
1972 will support both versions.
1974 * Added const modifier to buffer parameter for some ODR/BER encoding
1975 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1976 completeWAIS, odr_dumpBER.
1978 Fixed bug in client.c which caused a crash when a scanResponse didn't
1979 contain positionOfTerm.
1981 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1982 * will cause an error in a client if a non-YAZ target sends both a
1983 * list of Scan entries and non-surrogate diagnostics.
1985 Retrieval module enhancements. Tag sets may be typed in the reference
1986 to it. From the .abs-file the "tagset" directive takes a third optional
1987 integer type for the tag set referenced. From a .tag-file the "include"
1988 directive takes a third optional type as well. The old "type" directive
1989 in the tag set itself is still recognized but acts as the default type
1992 Backend interface change. Individual Scan terms returned from bend_scan
1993 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1994 in include/backend.h.
1996 Retrieval module enhancements. Multiple tag sets and attribute sets may
1997 be specified in abstract syntax specs. Revised the error/warning for
1998 logging messages reported by the retrieval module when reading the
2001 Object Identifier system (oid_..) changed. The API is backwards
2002 compatible but the oid-routines now allocates new OID's when needed.
2003 Raw OID's may be specified in oid_getvalbyname.
2005 YAZ now uses GNU configure to generate Makefile(s).
2007 * Minor changes in some of the member names of DeleteResultSetRequest and
2008 DeleteResultSetResponse. See include/proto.h.
2010 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2011 and added member 'languages' in TargetInfo (which was missing).
2013 Changed the way attribute sets are handled in the retrieval
2014 module. These are now cached, just like the abstract syntaxes
2017 Changed YAZ so that it links with compiled ASN.1.
2019 Added Explain-schema definitions and mapping routines. The following
2020 Explain categories have been implemented: AttributeDetails,
2021 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2023 Fixed minor bug in Windows version of Server Library.
2025 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2027 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2029 Added EXTERNAL: UNIverse Resource Report (non-standard).
2031 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2032 ENUMERATED and SET OF.
2034 * Added 'const' to some of the char pointer arguments for the
2035 functions, data1_read_node, data1_getelementbytagname,
2036 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2039 Fixed bug in data1_insert_taggeddata - the last_child member of
2040 parent wasn't initialised.
2042 * Changed data1_read_record and data1_read_node so that the supplied
2043 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2044 doesn't refer to any parts of the "SGML"-buffer.
2046 Fixed bug in server library (Windows version of statserv_remove).
2048 * Changed code so that it compiles as C++. The type definition
2049 of Odr_fun which is a member of Odr_arm was changed. The result is,
2050 that an explicit typecast is needed for the fun pointer when
2051 using Odr_arm - as in:
2052 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2054 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2056 Implemented the new structured date and time definition as approved
2057 by the ZIG. Added schemaId element to the specificTag in Espec-1
2058 (also approved at the last ZIG). Thanks to RVDM.
2060 Added some Object identifiers (RVDM).
2062 Changed the Update Extended Service (RVDM).
2064 Added command "refid" to client which specifies referenceId for
2065 the following requests.
2067 Implemented extended service handling for server. See ztest.c
2068 for an example as well as backend.h. New handlers are registerd
2069 in the Init handler.
2071 * Changed interface for sort in server.
2073 Added new members to statserv_options_block. It allows a server
2074 to read options from another source than just the command line. Thanks
2075 to Charles Woodfield.
2077 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2078 renamed to zboolean. Some C++ compilers complained about the name.
2080 Minor changes to gils.abs. Added index 's' (sort) on title
2081 and date/time-last-modified.
2083 --- 1.4pl2 1998/1/30
2085 Fixed bug in server library regarding inetd mode (-i). This bug
2086 was introduced by release 1.4.
2088 --- 1.4pl1 1998/1/29
2090 Added sort facility in client and backend server interface.
2092 Fixed problem with dependencies in Makefile(s).
2094 Fixed bugs for encoders/decoders of extended services and
2097 Implemented sub-tree feature for schemas. Sub-trees are
2098 referenced in *.abs-files. See explain.abs for an example
2099 of the use of this feature.
2101 Modified bib1.att; local attributes for ANY didn't include
2102 ANY itself (only affects use of the retrieval module).
2104 Fixed bug in plain SGML reader in function data1_read_node:
2105 tags with prefix "var" was incorrectly interpreted as variants.
2107 Added feature "sub-schemas" to enable references to - and definitions
2108 of - group of elements.
2110 * Removed member parent from type data1_element (in data1.h).
2112 Implemented function odr_nullval() that returns the value of
2115 * Removed member num_children from data1_node (in data1.h).
2117 Made NT service interface part of the server library. The
2118 function statserv_main uses the NT service when required and
2119 calls the statserv_start / statserv_close routines.
2121 Routine zget_SearchRequest and zget_PresentRequest fills
2122 resultSetName/Id member with "default" instead of "Default".
2124 Fixed memory leak in server. Request queue member wasn't freed.
2126 Fixed nmem_exit so that memory is freed.
2130 Revised the CCL parser utility to be thread safe.
2132 Added function, oid_ent_to_oid, to replace the function
2133 oid_getoidbyent, which is not thread safe.
2135 * Added nmem_init and nmem_exit to initialize and release
2136 NMEM resources. Function nmem_init should be called once in the
2137 initial thread before NMEM/ODR is used. statserv.c and client.c
2138 have been changed accordingly. The change was necessary to make
2139 NMEM thread safe. The NMEM memory pool is shared amongst threads
2140 in a process. Unix-based applications will still work fine without
2143 Added NT Services interface for the the Z39.50 (statserv) Server.
2144 Refer to the ztest.c source on the usage.
2146 Windows 95/NT port using MSVC5.0. Project files are included in the
2149 * Defined new 'global' handle for the retrieval (data1) system. The
2150 new handled, data1_handle, describes the state of the data1 system.
2151 This handle is passed as first argument to virtually all
2152 data1 related routines. The functions data1_create and data1_destroy
2153 creates and destroys a data1 handle respectively.
2155 Added ODR encode stream member to all backend request structures
2156 init, search, scan etc. This stream should be used to allocate all
2157 memory used for the response when thread safe operation is needed.
2159 Changed the comstack utility, cs_addstr, to be thread safe. The
2160 returned hostname string returned by the function is now part the
2163 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2164 function. The cs_straddr takes a COMSTACK handle as argument, so this
2165 function must be used after cs_create and before bind/connect.
2166 This function is thread safe.
2168 Moved test server to 'ztest' directory - generic server code still
2169 in 'server' directory.
2171 Made prefix query (pquery.c) utility thread safe.
2173 Added new function modifier YAZ_EXPORT to 'export' public DLL
2174 functions when using windows (see include/yconfig.h).
2176 Added definitions to the OID database (util/oid.c) (RVDM).
2178 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2180 Added call to ccl_rpn_delete in client program.
2182 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2183 release of RPN structure.
2185 Added support for C++, headers uses extern "C" for public definitions.
2186 With input from RVDM.
2188 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2189 Thanks to Ronald van der Meer (RVDM).
2191 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2193 Added support for private extensions to the OID database
2194 (oid_setprivateoids()). Thanks to RVDM.
2196 Added optional, physical ANY (key replication)
2198 Fixed null-reference problem in GRS-1 output filter.
2200 Proximity operator added to Prefix Query Format (PQF).
2202 In test client command "base" accepts multiple databases.
2204 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2208 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2210 Smallish bug-fixes in the new encoders/decoders (explain).
2212 Bug fixed in DeleteRequest.
2214 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2216 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2218 Added SOIF syntax (using private OID for now) to retrieval module and client.
2220 Added Update extended service.
2222 Added SearchResult-1 additional info structure.
2224 Added optional CCL (ISO8777) interpreter as separate module. Available
2227 --- 1.2 1996/6/10 (1st anniversary release)
2229 Added Summary record syntax. Lightly tested.
2231 Added OPAC record syntax. Untested.
2233 Added ResourceReport service encoders/decoders. Untested.
2235 Fixed bug in z_Unit - wrong tagging on unitSystem.
2237 Fixed bug in the DiagRecs decoder.
2239 Added options for max PDU size and session timeout to frontend-server.
2241 Added documentation of query-language parsers and other supporting utilities.
2243 [frontend-server] Added Attribute set to the bend_scanrequest API.
2245 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2246 surrogate diagnostics were generated.
2248 [retrieval] Allow multiple local values for attribute.
2250 [retrieval] Allow multiple attributes per element in .abs files. index type.
2252 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2254 --- 1.1pl2 1996/4/10
2256 Minor changes, mostly specific to Zebra's requirements (retrieval)
2260 Repaired bug in frontend server when running multiple listening
2261 endpoints in dynamic mode.
2263 z_External() now won't break if a known, ASN.1 value comes encapsulated
2264 in an octet-string. The value will pass through unmodified in an Odr_oct.
2266 Added a bit of code to the demo client to decode & display
2267 ASN.1-structured records represented in the octet-aligned branch of
2268 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2270 Added z_ext_getentbyref() to the ASN module. Doc updated.
2272 * Completed the SCAN definition in the ASN module. This may break SCAN
2273 code based on older YAZ-versions at compile-time. The fix is easy -
2276 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2277 under the SCAN definition. Remember to initialize this, server-people.
2279 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2280 that this does not extend to ODR and ASN.
2282 Comstack allows insertion of established socket (primarily for
2283 inetd-operation of servers). Doc updated.
2285 Front-end server can now start from the inetd in TCP mode. Doc
2288 --- 1.0pl4 1996/1/24
2292 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2293 the rank and record number.
2295 Adjustments to the frontend server.
2297 Fixed diagnostic BER dumper. It ignored the file argument.
2301 Various changes to retrieval module.
2303 Changed the union discriminators of the protocol files from enums to
2304 ints paired with #defines.
2306 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2309 *Changed operator in the RPN structure to 'roperator', again to avoid a
2312 Fixed problems in Explain decoders/encoders.
2314 --- 1.0pl2 1995/12/6
2316 Memory bug in log module fixed.
2318 --- 1.0pl1 1995/12/5
2320 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2322 Bug in Explain DatabaseInfo module fixed.
2324 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2328 The shift to v1.0 signals that we now consider the *core* functionality
2329 of YAZ reasonably stable (the core being more or less equivalent to
2330 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2331 tested (Explain not at all - though that will happen soonish).
2333 Minor changes to code to support Windows port.
2335 Various minor changes after we're getting to use GRS-1 & co. more.
2337 Added Espec-1 format.
2339 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2340 of the protocol and it cannot be selected when encoding (maps into 'string'
2341 when decoding). Needed to talk to some servers.
2343 Demo client can request simple element set names.
2345 Added Diagnostic Format encoders/decoders.
2347 Added simple Close handling to frontend server (no hooks for resource
2348 reporting yet), and demonstration client.
2350 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2352 --- 1.0b3 1995/08/24
2354 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2355 handled incorrectly when records were requested in the searchResponse. This
2356 will only affect you if you use the frontend-server.
2358 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2359 Test-client will ask for and print GRS1. Ztest will return dummy records
2362 Added Explain encoders/decoders to the service-level API. Untested.
2364 Added Extended Services: Item Order encoders and decoders to the Service-
2365 level API. Untested. We could use a recent copy of the pertinent bits
2366 of the ILL protocol to add those bits.
2368 Added diagnostic format 1 encoders/decoders to the service-level API.
2371 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2372 odr_cons.c, which causes a more correct output.
2374 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2375 was always set to 0 when no records were requested in the searchRequest.
2377 * Added better external-handling. This shouldn't harm old code that
2378 *encodes* externals. It can break code that looks for a
2379 'single-ASN1-type' representation, since those types that are known
2380 are now decoded immediately. Look at the SUTRS sample code in
2381 seshigh.c and client.c. Documentation updated.
2383 Handling of structured records in bend_fetchresponse. Length -1 marks
2384 structured record, type is deduced from format field.
2386 --- 1.0b2 1995/06/27
2387 Fairly quick maintenance release to add SUTRS support.
2389 Fixed handling of SUTRS records in the demonstration client.
2391 * Added format field to the bend_fetchrequest and bend_fetchresponce
2392 structures of the backend API (frontend server). When the record is
2393 returned, the value of the format field is mapped to an OID. The
2394 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2395 of the record. The special value VAL_NONE in the bend_request means
2396 that no specific format was requested by the client. Documentation
2397 updated accordingly. Test server (ztest) will return a fixed dummy
2398 SUTRS record if your client requests SUTRS.
2400 Documentation updated accordingly.
2402 You can now set external libraries and RANLIB support in the top-level
2406 First public release.
